To the Holders of Shares of Common Stock of
  Transco Energy Company:
 
                                  INTRODUCTION
 
  The Williams Companies, Inc. (the "Purchaser"), a Delaware corporation,
hereby offers to purchase up to 24,600,000 shares of Common Stock, par value
$0.50 per share (the "Shares"), of Transco Energy Company, a Delaware
corporation (the "Company"), together with the attached common share purchase
rights (the "Company Rights," and, unless the context otherwise requires,
deemed to be included in all references to "Shares"), at a price of $17.50 per
Share, net to the seller in cash, without interest thereon, upon the terms and
subject to the conditions set forth in this Offer to Purchase and in the
related Letter of Transmittal (which, as amended from time to time, together
constitute the "Offer"). The Company has agreed in the Merger Agreement (as
hereinafter defined), subject to the terms of the Merger Agreement, to effect a
redemption of the Company Rights for $.05 per Company Right immediately prior
to the Purchaser's acceptance for payment of Shares pursuant to the Offer, and
that the redemption price in respect of Company Rights attached to Shares
purchased pursuant to the Offer will be paid to and retained by the Purchaser.
 
  Tendering stockholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 of the Letter of
Transmittal, stock transfer taxes on the purchase of Shares pursuant to the
Offer. The Purchaser will pay all charges and expenses of Smith Barney Inc., as
Dealer Manager (in such capacity, the "Dealer Manager"), Chemical Bank, as
Depositary (the "Depositary"), and Morrow & Co., as Information Agent (the
"Information Agent"), incurred in connection with the Offer. See Section 16.
 
  THE BOARD OF DIRECTORS OF THE COMPANY (THE "COMPANY BOARD") HAS UNANIMOUSLY
DETERMINED (WITH ONE DIRECTOR ABSENT) THAT THE OFFER AND THE MERGER, TAKEN
TOGETHER, ARE FAIR TO AND IN THE BEST INTERESTS OF, THE STOCKHOLDERS OF THE
COMPANY AND RECOMMENDS THAT SUCH HOLDERS OF SHARES ACCEPT THE OFFER AND TENDER
THEIR SHARES PURSUANT TO THE OFFER.
 
  The Company has advised the Purchaser that Merrill Lynch, Pierce, Fenner, &
Smith Incorporated ("Merrill Lynch") has delivered to the Company Board its
opinion that, as of the date of the opinion, the consideration to be received
by the stockholders of the Company (other than the Purchaser and its
affiliates) pursuant to the Offer and the Merger, taken as a whole, is fair to
such stockholders from a financial point of view. A copy of the opinion of
Merrill Lynch, which sets forth the procedures followed, the factors considered
and the assumptions made by Merrill Lynch, is contained in the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9"),
which is being mailed to stockholders herewith.
 
  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, AT LEAST 20,900,000 SHARES
BEING VALIDLY TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER
(THE "MINIMUM CONDITION"). THE OFFER IS ALSO SUBJECT TO THE EXPIRATION OR
TERMINATION OF THE APPLICABLE WAITING PERIODS UNDER THE HSR ACT (AS HEREINAFTER
DEFINED) AND TO OTHER TERMS AND CONDITIONS CONTAINED IN THIS OFFER TO PURCHASE.
SEE SECTION 14.
 
  The Minimum Condition requires that at least 20,900,000 Shares be validly
tendered and not withdrawn before the expiration of the Offer. According to the
Company, as of December 9, 1994, there were 40,927,847 Shares outstanding
(including 216,900 Shares of restricted stock) and 3,321,628 Shares reserved
for issuance upon exercise of then outstanding options to acquire Shares or in
respect of outstanding restricted stock or deferred stock units under the
Company's stock option plans. In addition, according to the Company, as of the
same date, there were 2,979,900 shares of the Company's $4.75 series Cumulative
Convertible Preferred Stock, stated value $50 per share (the "Company $4.75
Preferred Stock"), and 2,500,000 shares of the Company's $3.50 series
Cumulative Convertible Preferred Stock, stated value $50 per share (the
"Company $3.50 Preferred Stock" and, together with the Company $4.75 Preferred
Stock, the "Company Preferred Stock"). According to the Company, each share of
Company $4.75 Preferred Stock is currently convertible into .894 of a Share,
and each share of Company $3.50 Preferred Stock is currently convertible into
2.5 Shares.
 
                                       3

  The Purchaser and the Company are filing with the Federal Trade Commission
(the "FTC") and the Antitrust Division of the Department of Justice (the
"Antitrust Division") Premerger Notification and Report Forms under the Hart-
Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"),
with respect to the Offer and the Stock Option Agreement (as hereinafter
defined). The waiting period under the HSR Act applicable to the Purchaser's
acquisition of Shares will expire at 11:59 p.m., New York City time, on the
fifteenth day following such filings, unless the waiting period is earlier
terminated by the FTC and the Antitrust Division or extended by a request from
the FTC or the Antitrust Division for additional information or documentary
material prior to the expiration of the waiting period. See Section 15 for
additional information regarding the HSR Act and other antitrust
considerations.
 
  Certain other conditions to consummation of the Offer are described in
Section 14. The Purchaser expressly reserves the right in its sole discretion
to waive any one or more of the conditions to the Offer, other than the Minimum
Condition. See Section 14.
 
  The Offer is being made pursuant to an Agreement and Plan of Merger, dated as
of December 12, 1994 (the "Merger Agreement"), by and among the Purchaser, WC
Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary of the
Purchaser ("Sub"), and the Company. The Merger Agreement provides, among other
things, that, as soon as practicable after the purchase of Shares pursuant to
the Offer, the approval of the Merger (as hereinafter defined) by the
stockholders of the Company, and the satisfaction of the other conditions set
forth in the Merger Agreement and described herein, Sub will be merged with and
into the Company (the "Merger") in accordance with the relevant provisions of
the General Corporation Law of the State of Delaware ("Delaware Law").
Following consummation of the Merger, the Company will continue as the
surviving corporation (the "Surviving Corporation") and a wholly-owned
subsidiary of the Purchaser.
 
  At the effective time of the Merger (the "Effective Time"), in the event that
24,600,000 Shares are purchased pursuant to the Offer, each Share that is
issued and outstanding immediately prior to the Effective Time (other than
Shares held in the treasury of the Company, Shares owned by the Purchaser or
any direct or indirect wholly-owned subsidiary of the Purchaser ("Retired
Shares"), or dissenting Shares (collectively, "Retired or Dissenting Shares"))
will be converted into the right to receive .625 of a share of Common Stock,
par value $1.00 per share, of the Purchaser (the "Purchaser Common Stock") and
.3125 attached preferred stock purchase rights (the "Purchaser Rights"). In the
event that less than 24,600,000 Shares, but at least 20,900,000 Shares, are
purchased pursuant to the Offer, each Share that is issued and outstanding
immediately prior to the Effective Time (other than Retired or Dissenting
Shares) will be converted into the right to receive (i) an amount in cash (the
"Per Share Cash Amount") equal to (x) the excess of (A) the product of (1)
$17.50 or such higher price as may be paid in the Offer (the "Offer Price"),
and (2) the excess of 24,600,000 over the number of Shares purchased pursuant
to the Offer, over (B) the aggregate amount paid in the redemption of Company
Rights not acquired pursuant to the Offer, divided by (y) the number of Shares
outstanding immediately prior to the Effective Time (other than Retired Shares)
and (ii) the fraction of a share of Purchaser Common Stock equal to (A) the
product of (1) .625 and (2) the excess of the Offer Price over the Per Share
Cash Amount, divided by (B) the Offer Price (such fractional amount of a share
of Purchaser Common Stock, the "Conversion Number"), together with a fraction
of attached Purchaser Rights equal to the Conversion Number divided by 2. See
Sections 10 and 11.
 
  In addition, also at the Effective Time, each issued and outstanding share of
Company $4.75 Preferred Stock and each issued and outstanding share of Company
$3.50 Preferred Stock (in each case other than shares that are owned by the
Company as treasury stock, or owned by the Purchaser or any wholly-owned
subsidiary of the Purchaser, or, to the extent appraisal rights are available
to such holders, dissenting shares) will be converted into the right to receive
one share of preferred stock of the Purchaser which, in the case of the Company
$4.75 Preferred Stock, will be designated the Purchaser's $4.75 Series
Cumulative Convertible Preferred Stock (the "Purchaser $4.75 Preferred Stock")
and, in the case of the Company $3.50 Preferred Stock, will be designated the
Purchaser's $3.50 Series Cumulative Convertible Preferred Stock (the "Purchaser
$3.50 Preferred Stock" and, together with the Purchaser $4.75 Preferred Stock,
collectively the
 
                                       4

"Purchaser New Preferred Stock"). The Purchaser $4.75 Preferred Stock will be
initially convertible into .5588 of a share of Purchaser Common Stock and the
Purchaser $3.50 Preferred Stock will be initially convertible into 1.5625
shares of Purchaser Common Stock. Each will have the designation, preferences
and rights set forth for such stock in the Merger Agreement.
 
  THE OFFER DOES NOT CONSTITUTE AN OFFER TO SELL OR A SOLICITATION OF AN OFFER
TO BUY ANY SECURITIES OF THE PURCHASER. SUCH AN OFFER MAY BE MADE ONLY PURSUANT
TO A PROSPECTUS.
 
  Pursuant to the Merger Agreement and subject to compliance with applicable
law and the receipt of any third party consents which may be necessary, the
Purchaser has reserved the right to acquire shares of Purchaser Common Stock
and of its existing preferred stock pursuant to its previously announced open
market purchase programs. See Section 10. In addition, although the Purchaser
has made no final determination in this regard, and subject to the receipt of
any third party consents which may be necessary, the Purchaser expects that it
will cause to be redeemed all of the shares of Purchaser $4.75 Preferred Stock
to be issued in the Merger prior to the end of 1995.
 
  The consummation of the Merger is subject to the satisfaction or waiver of
certain conditions, including the approval and adoption of the Merger Agreement
by the requisite vote of the stockholders of the Company. See Section 11. A
proxy or information statement (which will also constitute a prospectus for the
securities of the Purchaser issuable in the Merger as to which delivery of a
prospectus is required) containing detailed information concerning the Merger
will be furnished to holders of Shares in connection with a special meeting of
stockholders to be called by the Company to vote on the Merger. The Purchaser
will vote all Shares acquired pursuant to the Offer in favor of the Merger.
Under the Company's Second Restated Certificate of Incorporation and Delaware
Law, the affirmative vote of the holders of a majority of the outstanding
Shares is required to approve and adopt the Merger Agreement and the Merger. It
is expected that, if the Purchaser acquires 20,900,000 Shares, the minimum
number of Shares to be purchased in the Offer, it will own a majority of the
outstanding Shares and, accordingly, will have sufficient voting power to
approve and adopt the Merger Agreement and the Merger without the vote of any
other stockholder of the Company.
 
  Simultaneously with entering into the Merger Agreement, the Purchaser and the
Company entered into a Stock Option Agreement dated as of December 12, 1994
(the "Stock Option Agreement"), pursuant to which the Company granted to the
Purchaser an option to purchase, upon the terms and subject to the conditions
set forth therein, up to 7,500,000 previously unissued Shares at a price of
$17.50 per Share. Under the terms of the Stock Option Agreement, the Company
has the right, upon exercise of such option by the Purchaser, to deliver an
amount in cash (not in excess of $2.00 per option Share) in lieu of the
delivery of Shares. Based on the 40,927,847 Shares represented by the Company
to be outstanding at December 9, 1994, the Purchaser beneficially owns
approximately 15.5% of the Shares that would be outstanding assuming an
exercise in full by the Purchaser of the Stock Option Agreement and a delivery
of the related Shares by the Company thereunder. See Section 10.
 
  The Offer is not being made to (nor will tenders be accepted from) the
holders of shares of Company Preferred Stock. Accordingly, holders of shares of
Company Preferred Stock desiring to tender Shares issuable upon conversion
thereof must convert such shares into Shares in accordance with the terms
thereof and then tender the Shares issued upon such conversion pursuant to the
Offer. There can be no assurance that Shares issued upon such conversion will
be received in time to allow the holders thereof to tender such Shares pursuant
to the Offer. Based on the current conversion rates, the equivalent conversion
price for each share of Company $3.50 Preferred Stock is $20.00 and the
equivalent conversion price for each share of Company $4.75 Preferred Stock is
$55.93, each of which exceeds the Offer Price of $17.50. Neither the Purchaser
nor the Company is making any recommendation that holders of shares of Company
Preferred Stock so convert their shares.
 
  THIS OFFER TO PURCHASE AND THE LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.
 
                                       5

                                THE TENDER OFFER
 
  1. TERMS OF THE OFFER; PRORATION. Upon the terms and subject to the
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of any extension or amendment), the Purchaser will accept
for payment and pay for up to 24,600,000 Shares validly tendered prior to the
Expiration Date (as hereinafter defined) and not withdrawn in accordance with
Section 4. The term "Expiration Date" means 12:00 Midnight, New York City time,
on Tuesday, January 17, 1995, unless and until the Purchaser, in its sole
discretion (but subject to the terms and conditions of the Merger Agreement),
shall have extended the period of time during which the Offer is open, in which
event the term "Expiration Date" shall mean the latest time and date at which
the Offer, as so extended by the Purchaser, shall expire.
 
  Consummation of the Offer is conditioned upon, among other things,
satisfaction of the Minimum Condition and the expiration or termination of the
applicable waiting period under the HSR Act. If such conditions are not
satisfied or any or all of the other events set forth in Section 14 shall have
occurred or shall be determined by the Purchaser to have occurred prior to the
Expiration Date, the Purchaser reserves the right (but subject to the terms and
conditions of the Merger Agreement) to (i) decline to purchase any or all of
the Shares tendered and terminate the Offer, and return all tendered Shares to
tendering stockholders, (ii) waive or reduce the Minimum Condition or waive in
whole or in part any or all of the other conditions and, subject to complying
with applicable rules and regulations of the Securities and Exchange Commission
(the "Commission"), purchase all Shares validly tendered, or (iii) extend the
Offer and, subject to the right of stockholders to withdraw Shares until the
Expiration Date, retain the Shares which have been tendered during the period
or periods for which the Offer is extended. See Sections 10 and 14.
 
  Upon the terms and subject to the conditions of the Offer, if more than
24,600,000 Shares are validly tendered and not withdrawn prior to the
Expiration Date, the Purchaser will, upon the terms and subject to the
conditions of the Offer, purchase 24,600,000 Shares on a pro rata basis (with
adjustments to avoid purchases of fractional Shares) based upon the number of
Shares validly tendered and not withdrawn prior to the Expiration Date.
 
  Because of the difficulty of determining the precise number of Shares
properly tendered and not withdrawn, if proration is required, the Purchaser
does not expect to be able to announce the final proration factor until
approximately seven New York Stock Exchange, Inc. (the "NYSE") trading days
after the Expiration Date. Preliminary results of proration will be announced
by press release as promptly as practicable after the Expiration Date.
Stockholders may obtain such preliminary information from the Information Agent
and may be able to obtain such information from their brokers. The Purchaser
will not pay for any Shares accepted for payment pursuant to the Offer until
the final proration factor is known.
 
  The Purchaser expressly reserves the right, in its sole discretion (but
subject to the terms and conditions of the Merger Agreement), at any time and
from time to time, to extend for any reason the period of time during which the
Offer is open, including the occurrence of any of the events specified in
Section 14, by giving oral or written notice of such extension to the
Depositary. During any such extension, all Shares previously tendered and not
withdrawn will remain subject to the Offer, subject to the rights of a
tendering stockholder to withdraw its Shares. Pursuant to the terms of the
Merger Agreement, and subject to the proration and other terms of the Offer and
the Merger Agreement and the satisfaction of all the conditions referred to in
Section 14, the Purchaser has agreed to accept for payment and pay for all
Shares validly tendered and not withdrawn pursuant to the Offer as soon as
practicable after the Expiration Date. See Sections 4 and 10.
 
  Subject to the applicable regulations of the Commission, the Purchaser also
expressly reserves the right, in its sole discretion (but subject to the terms
and conditions of the Merger Agreement), at any time and from time to time, to
(i) increase the price per Share payable pursuant to the Offer, (ii) increase
on one occasion the number of Shares to be purchased in the Offer; provided,
that (x) any increase in the number of Shares to be purchased which requires an
extension of the Offer beyond its then applicable expiration date in accordance
with applicable law must provide for an increase of at least 4,000,000 Shares
and (y) any increase
 
                                       6

in the number of Shares sought at a time when the average closing sale prices
on the NYSE for shares of Purchaser Common Stock for the ten trading days
immediately preceding the date of public notice of the increase exceeds $28.00
may only be made with the consent of the Company, (iii) to terminate the Offer
and not accept for payment any Shares if any of the conditions referred to in
Section 14 has not been satisfied or upon the occurrence of any of the events
specified in Section 14 or (iv) to waive any condition (other than the Minimum
Condition) or otherwise amend the Offer in any respect by giving oral or
written notice of such delay, termination, waiver or amendment to the
Depositary and by making a public announcement thereof. Subject to the terms of
the Merger Agreement, the Purchaser has agreed, if such conditions have not
been satisfied as of the then applicable expiration date of the Offer, that the
Purchaser will extend the Offer from time to time until the earlier of the
consummation of the Offer or March 16, 1995. See Section 10.
 
  The Merger Agreement provides that, without the prior written consent of the
Company, the Purchaser will not (i) decrease the price per Share payable
pursuant to the Offer, (ii) decrease or (other than as described in the
immediately preceding paragraph) increase the number of Shares to be purchased
in the Offer, (iii) change the form of consideration payable in the Offer, (iv)
add to or change the conditions of the Offer, (v) change or waive the Minimum
Condition or (vi) make any other change in the terms or conditions of the Offer
which is adverse to the holders of Shares. The Purchaser acknowledges that (i)
Rule 14e-1(c) under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), requires the Purchaser to pay the consideration offered or
return the Shares tendered promptly after the termination or withdrawal of the
Offer, and (ii) the Purchaser may not delay acceptance for payment of, or
payment for, any Shares upon the occurrence of any of the events specified in
Section 14 without extending the period of time during which the Offer is open.
 
  Any such extension, delay, termination, waiver or amendment will be followed
as promptly as practicable by public announcement thereof, such announcement in
the case of an extension to be made no later than 9:00 a.m., New York City
time, on the next business day after the previously scheduled Expiration Date.
Subject to applicable law (including Rules 14d-4(c), 14d-6(d) and 14e-1 under
the Exchange Act, which require that material changes be promptly disseminated
to stockholders in a manner reasonably designed to inform them of such changes)
and without limiting the manner in which the Purchaser may choose to make any
public announcement, the Purchaser shall have no obligation to publish,
advertise or otherwise communicate any such public announcement other than by
issuing a press release to the Dow Jones News Service.
 
  If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer, or if it waives a material condition of the
Offer, the Purchaser will extend the Offer to the extent required by Rules 14d-
4(c), 14d-6(d) and 14e-1 under the Exchange Act. Subject to the conditions
described above, the Purchaser reserves the right (but subject to the terms and
conditions of the Merger Agreement) to accept for payment more than 24,600,000
Shares pursuant to the Offer. The Purchaser has no present intention of
exercising such right.
 
  Subject to the terms and conditions of the Merger Agreement, if, prior to the
Expiration Date, the Purchaser should decide to increase or decrease the number
of Shares being sought or to increase or decrease the consideration being
offered in the Offer, such increase or decrease in the number of Shares being
sought or such increase or decrease in the consideration being offered will be
applicable to all stockholders whose Shares are accepted for payment pursuant
to the Offer and, if at the time notice of any such increase or decrease in the
number of Shares being sought or such increase or decrease in the consideration
being offered is first published, sent or given to holders of such Shares, the
Offer is scheduled to expire at any time earlier than the period ending on the
tenth business day from and including the date that such notice is first so
published, sent or given, the Offer will be extended at least until the
expiration of such ten business day period. For purposes of the Offer a
"business day" means any day other than a Saturday, Sunday or federal holiday
and consists of the time period from 12:01 a.m. through 12:00 Midnight, New
York City time.
 
                                       7

  The Company has provided the Purchaser with the Company's stockholder list
and security position listings for the purpose of disseminating the Offer to
holders of Shares. This Offer to Purchase and the related Letter of Transmittal
will be mailed to record holders of Shares whose names appear on the Company's
stockholder list and will be furnished, for subsequent transmittal to
beneficial owners of Shares, to brokers, dealers, commercial banks, trust
companies and similar persons whose names, or the names of whose nominees,
appear on the stockholder list or, if applicable, who are listed as
participants in a clearing agency's security position listing.
 
  2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES. Upon the terms and subject
to the conditions of the Offer (including, if the Offer is extended or amended,
the terms and conditions of any such extension or amendment), the Purchaser
will purchase, by accepting for payment, and will pay for, up to 24,600,000
Shares validly tendered prior to the Expiration Date (and not properly
withdrawn in accordance with Section 4) as soon as practicable after the later
to occur of (i) the Expiration Date and (ii) the satisfaction or waiver of the
conditions set forth in Section 14. Any determination concerning the
satisfaction of such terms and conditions shall be within the reasonable
discretion of the Purchaser. See Section 14. Subject to the applicable rules of
the Commission, the Purchaser expressly reserves the right (but subject to the
terms and conditions of the Merger Agreement) to delay acceptance for payment
of, or payment for, Shares pending receipt of any regulatory approval specified
in Section 15 or in order to comply in whole or in part with any applicable
law.
 
  In all cases, payment for Shares purchased pursuant to the Offer will be made
only after timely receipt by the Depositary of (i) the certificates evidencing
such Shares (the "Share Certificates") or timely confirmation of a book-entry
transfer (a "Book-Entry Confirmation") of such Shares, if such procedure is
available, into the Depositary's account at The Depository Trust Company, the
Midwest Securities Trust Company or the Philadelphia Depository Trust Company
(each a "Book-Entry Transfer Facility" and, collectively, the "Book-Entry
Transfer Facilities") pursuant to the procedure set forth in Section 3, (ii)
the Letter of Transmittal (or facsimile thereof), properly completed and duly
executed, or an Agent's Message (as defined below) and (iii) any other
documents required by the Letter of Transmittal.
 
  The term "Agent's Message" means a message, transmitted by a Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that such Book-Entry Transfer Facility
has received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Shares, that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that the
Purchaser may enforce such agreement against the participant.
 
  Payment for the Shares accepted for payment pursuant to the Offer will be
delayed in the event of proration due to the difficulty of determining the
number of Shares validly tendered and not withdrawn. See Section 1.
 
  For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment (and thereby purchased) tendered Shares validly tendered and not
properly withdrawn if, as and when the Purchaser gives oral or written notice
to the Depositary of the Purchaser's acceptance of such Shares for payment.
Payment for Shares accepted pursuant to the Offer will be made by deposit of
the aggregate purchase price therefor with the Depositary, which will act as
agent for tendering stockholders for the purpose of receiving payment from the
Purchaser and transmitting payment to such tendering stockholders. Under no
circumstances will interest on the purchase price for Shares be paid by the
Purchaser by reason of any delay in making such payment. Upon the deposit of
funds with the Depositary for the purpose of making payments to tendering
stockholders, the Purchaser's obligation to make such payment shall be
satisfied and tendering stockholders must thereafter look solely to the
Depositary for payment of amounts owed to them by reason of the acceptance for
payment of Shares pursuant to the Offer. The Purchaser will pay any stock
transfer taxes incident to the transfer to it of validly tendered Shares,
except as otherwise provided in Instruction 6 of the Letter of Transmittal, as
well as any charges and expenses of the Depositary, the Dealer Manager and the
Information Agent.
 
                                       8

  If any tendered Shares are not accepted for payment for any reason pursuant
to the terms and conditions of the Offer (including proration due to tenders of
Shares pursuant to the Offer in excess of the maximum number of shares to be
purchased pursuant to the Offer), or if Share Certificates are submitted
evidencing more Shares than are tendered, Share Certificates evidencing
unpurchased Shares will be returned, without expense to the tendering
stockholder (or, in the case of Shares tendered by book-entry transfer into the
Depositary's account at a Book-Entry Transfer Facility pursuant to the
procedure set forth in Section 3, such Shares will be credited to an account
maintained at such Book-Entry Transfer Facility), as promptly as practicable
following the expiration or termination of the Offer.
 
  3. PROCEDURES FOR TENDERING SHARES.
 
  Valid Tender of Shares. In order for Shares to be validly tendered pursuant
to the Offer, the Letter of Transmittal or a facsimile thereof, properly
completed and duly executed, with any required signature guarantees, or an
Agent's Message in connection with a book-entry delivery of Shares, and any
other required documents, must be received by the Depositary at one of its
addresses set forth on the back cover page of this Offer to Purchase prior to
the Expiration Date and either (i) the Share Certificates evidencing tendered
Shares must be received by the Depositary along with the Letter of Transmittal,
or (ii) Shares must be tendered pursuant to the procedure for book-entry
transfer described below and a Book-Entry Confirmation must be received by the
Depositary, in each case prior to the Expiration Date, or (iii) the tendering
stockholder must comply with the guaranteed delivery procedures described
below.
 
  THE METHOD OF DELIVERY OF SHARE CERTIFICATES AND ALL OTHER REQUIRED
DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY TRANSFER FACILITY, IS AT
THE OPTION AND RISK OF THE TENDERING STOCKHOLDER, AND THE DELIVERY WILL BE
DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF DELIVERY IS BY
MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY
DELIVERY.
 
  Book-Entry Transfer. The Depositary will establish an account with respect to
the Shares at each Book-Entry Transfer Facility for purposes of the Offer
within two business days after the date of this Offer to Purchase, and any
financial institution that is a participant in any of the Book-Entry Transfer
Facilities' systems may make book-entry delivery of Shares by causing a Book-
Entry Transfer Facility to transfer such Shares into the Depositary's account
at a Book-Entry Transfer Facility in accordance with such Book-Entry Transfer
Facility's procedures for transfer. However, although delivery of Shares may be
effected through book-entry transfer at a Book-Entry Transfer Facility, the
Letter of Transmittal or facsimile thereof, with any required signature
guarantees, or an Agent's Message in connection with a book-entry delivery of
Shares, and any other required documents, must, in any case, be transmitted to
and received by the Depositary at one of its addresses set forth on the back
cover of this Offer to Purchase prior to the Expiration Date or the guaranteed
delivery procedures described below must be complied with.
 
  DELIVERY OF DOCUMENTS TO A BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE WITH
THE BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY TO
THE DEPOSITARY.
 
  Signature Guarantees. Signatures on all Letters of Transmittal must be
guaranteed by a member firm of a registered national securities exchange, a
member of the National Association of Securities Dealers, Inc. ("NASD") or a
commercial bank or trust company having an office or correspondent in the
United States (each of the foregoing being referred to as an "Eligible
Institution"), except in cases where Shares are tendered (i) by a registered
holder of Shares who has not completed either the box entitled "Special
Delivery Instructions" or the box entitled "Special Payment Instructions" on
the Letter of Transmittal, or (ii) for the account of an Eligible Institution.
See Instruction 1 of the Letter of Transmittal.
 
  If a Share Certificate is registered in the name of a person other than the
signer of the Letter of Transmittal, or if payment is to be made, or a Share
Certificate not accepted for payment or not tendered is to be returned, to a
person other than the registered holder(s), then the Share Certificate must be
endorsed or
 
                                       9

accompanied by appropriate stock powers, in either case signed exactly as the
name(s) of the registered holder(s) appear on the Share Certificate, with the
signature(s) on such Share Certificate or stock powers guaranteed as described
above. See Instructions 1 and 5 of the Letter of Transmittal.
 
  Guaranteed Delivery. If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's Share Certificates are not immediately
available or time will not permit all required documents to reach the
Depositary prior to the Expiration Date or the procedure for book-entry
transfer cannot be completed on a timely basis, such Shares may nevertheless be
tendered if all the following conditions are satisfied:
 
    (i) the tender is made by or through an Eligible Institution;
 
    (ii) a properly completed and duly executed Notice of Guaranteed
  Delivery, substantially in the form provided by the Purchaser herewith, is
  received by the Depositary as provided below prior to the Expiration Date;
  and
 
    (iii) in the case of a guarantee of Shares, the Share Certificates for
  all tendered Shares, in proper form for transfer, or a Book-Entry
  Confirmation, together with a properly completed and duly executed Letter
  of Transmittal (or manually signed facsimile thereof) with any required
  signature guarantee (or, in the case of a book-entry transfer, an Agent's
  Message) and any other documents required by such Letter of Transmittal,
  are received by the Depositary within five NYSE trading days after the date
  of execution of the Notice of Guaranteed Delivery.
 
  Any Notice of Guaranteed Delivery may be delivered by hand or transmitted by
telegram, facsimile transmission or mail to the Depositary and must include a
guarantee by an Eligible Institution in the form set forth in the Notice of
Guaranteed Delivery.
 
  Notwithstanding any other provision hereof, payment for Shares purchased
pursuant to the Offer will, in all cases, be made only after timely receipt by
the Depositary of (i) the Share Certificates evidencing such Shares, or a Book-
Entry Confirmation of the delivery of such Shares, if available, (ii) a
properly completed and duly executed Letter of Transmittal (or manually signed
facsimile thereof) (or, in the case of a book-entry transfer, an Agent's
Message) and (iii) any other documents required by the Letter of Transmittal.
 
  Backup Federal Withholding Tax. Unless an exemption applies under the
applicable law and regulations concerning "backup withholding" of federal
income tax, the Depositary will be required to withhold, and will withhold, 31%
of the gross proceeds otherwise payable to a stockholder or other payee with
respect to Shares purchased pursuant to the Offer if the stockholder does not
provide such stockholder's taxpayer identification number (social security
number or employer identification number) and certify that such number is
correct. Each tendering stockholder should complete and sign the main signature
form and the Substitute Form W-9 included as part of the Letter of Transmittal,
so as to provide the information and certification necessary to avoid backup
withholding, unless an applicable exemption exists and is proved in a manner
satisfactory to the Purchaser and the Depositary. See Instruction 10 of the
Letter of Transmittal.
 
  Appointment as Proxy. By executing a Letter of Transmittal as set forth
above, a tendering stockholder irrevocably appoints designees of the Purchaser
as such stockholder's attorneys-in-fact and proxies, in the manner set forth in
the Letter of Transmittal, each with full power of substitution, to the full
extent of such stockholder's rights with respect to the Shares tendered by such
stockholder and accepted for payment by the Purchaser (and any and all non-cash
dividends, distributions, rights, other Shares, or other securities issued or
issuable in respect of such Shares on or after the date of this Offer to
Purchase). All such proxies shall be considered coupled with an interest in the
tendered Shares. This appointment will be effective if, when, and only to the
extent that, the Purchaser accepts such Shares for payment pursuant to the
Offer. Upon such acceptance for payment, all prior proxies given by such
stockholder with respect to such Shares
 
                                       10

and other securities will, without further action, be revoked, and no
subsequent proxies may be given. The designees of the Purchaser will, with
respect to the Shares and other securities for which the appointment is
effective, be empowered to exercise all voting and other rights of such
stockholder as they in their sole discretion may deem proper at any annual,
special, adjourned or postponed meeting of the Company's stockholders, by
written consent or otherwise, and the Purchaser reserves the right to require
that, in order for Shares or other securities to be deemed validly tendered,
immediately upon the Purchaser's acceptance for payment of such Shares the
Purchaser must be able to exercise full voting rights with respect to such
Shares. See Section 15.
 
  Treatment of Company Rights. By executing a Letter of Transmittal as set
forth above, a tendering stockholder confirms such stockholder's agreement that
the amount paid by the Company in redemption of the Company Rights attached to
Shares of such stockholders acquired pursuant to the Offer will be paid to and
retained by the Purchaser. Amounts paid in redemption of Company Rights
attached to other Shares are not affected by the foregoing and will be paid to
holders of Company Rights in accordance with the terms of the Company's Rights
Agreement, dated as of January 13, 1986, as amended (the "Company Rights
Agreement").
 
  Determination of Validity. All questions as to the validity, form,
eligibility (including time of receipt) and acceptance for payment of any
tendered Shares pursuant to any of the procedures described above will be
determined by the Purchaser, in its sole discretion, whose determination will
be final and binding on all parties. The Purchaser reserves the absolute right
to reject any or all tenders of any Shares determined by it not to be in proper
form or if the acceptance for payment of, or payment for, such Shares may, in
the opinion of the Purchaser's counsel, be unlawful. The Purchaser also
reserves the absolute right, in its sole discretion, to waive any of the
conditions of the Offer or any defect or irregularity in any tender with
respect to Shares of any particular stockholder, whether or not similar defects
or irregularities are waived in the case of other stockholders. No tender of
Shares will be deemed to have been validly made until all defects and
irregularities have been cured or waived.
 
  The Purchaser's interpretation of the terms and conditions of the Offer
(including the Letter of Transmittal and the instructions thereto) will be
final and binding. None of the Purchaser, the Dealer Manager, the Depositary,
the Information Agent or any other person will be under any duty to give
notification of any defects or irregularities in tenders or will incur any
liability for failure to give any such notification.
 
  The Purchaser's acceptance for payment of Shares tendered pursuant to the
Offer will constitute a binding agreement between the tendering stockholder and
the Purchaser upon the terms and subject to the conditions of the Offer,
including such stockholder's agreement that such tender has been made in
compliance with Rule 14e-4 promulgated under the Exchange Act which requires in
substance that a tendering stockholder own all Shares tendered pursuant to the
Offer.
 
  4. WITHDRAWAL RIGHTS. Except as otherwise provided in this Section 4, tenders
of Shares made pursuant to the Offer are irrevocable. Shares tendered pursuant
to the Offer may be withdrawn at any time prior to the Expiration Date and,
unless theretofore accepted for payment by the Purchaser pursuant to the Offer,
may also be withdrawn at any time after February 13, 1995.
 
  If the Purchaser extends the Offer, is delayed in its acceptance for payment
of Shares or is unable to accept Shares for payment pursuant to the Offer for
any reason, then, without prejudice to the Purchaser's rights under the Offer,
the Depositary may, nevertheless, on behalf of the Purchaser, retain tendered
Shares, and such Shares may not be withdrawn except to the extent that
tendering stockholders are entitled to withdrawal rights as described in this
Section 4. Any such delay will be by an extension of the Offer to the extent
required by law.

                                       11

  For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase. Any
such notice of withdrawal must specify the name of the person who tendered the
Shares to be withdrawn, the number of Shares to be withdrawn and the name of
the registered holder, if different from that of the person who tendered such
Shares. If Share Certificates evidencing Shares to be withdrawn have been
delivered or otherwise identified to the Depositary, then, prior to the release
of such Share Certificates, the serial numbers shown on such Share Certificates
must be submitted to the Depositary and the signature(s) on the notice of
withdrawal must be guaranteed by an Eligible Institution, unless such Shares
have been tendered for the account of an Eligible Institution. If Shares have
been tendered pursuant to the procedure for book-entry transfer as set forth in
Section 3, any notice of withdrawal must also specify the name and number of
the account at the Book-Entry Transfer Facility to be credited with the
withdrawn Shares.
 
  All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser, in its sole
discretion, whose determination will be final and binding. None of the
Purchaser, the Dealer Manager, the Depositary, the Information Agent or any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure
to give any such notification.
 
  Any Shares properly withdrawn will thereafter be deemed to not have been
validly tendered for purposes of the Offer. However, withdrawn Shares may be
re-tendered at any time prior to the Expiration Date by following one of the
procedures described in Section 3.
 
  5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES. The following discussion is a
summary of the material federal income tax consequences of the Offer and the
Merger to holders of Shares who hold the Shares as capital assets. The
discussion set forth below is for general information only and may not apply to
particular categories of holders of Shares subject to special treatment under
the Internal Revenue Code of 1986, as amended (the "Code").
 
  Consequences of the Offer and the Proposed Merger Generally. The Offer and
the Merger will be taxable transactions for federal income tax purposes and may
be taxable transactions for foreign, state and local income and other tax
purposes as well. This will be the case whether a holder of Shares participates
only in the Offer or only in the Merger or partly in both transactions.
 
  In general, a stockholder of the Company who, pursuant to the Offer,
exchanges Shares for cash will recognize capital gain or loss on the date of
acceptance of Shares for payment in an amount equal to the difference between
the amount of cash received (exclusive of cash attributable to the redemption
price for Company Rights, as described below) and the stockholder's tax basis
in the Shares accepted. The gain or loss will be long-term capital gain or loss
if, as of such date, the holder thereof has held such Shares for more than one
year.
 
  In general, a stockholder of the Company who, pursuant to the Merger,
exchanges Shares for Purchaser Common Stock (which includes attached Purchaser
Rights) and cash (if any) will recognize capital gain or loss at the Effective
Time in an amount equal to the difference between the fair market value of the
Purchaser Common Stock (which includes attached Purchaser Rights) and cash (if
any) received and the stockholder's tax basis in the Shares surrendered. The
gain or loss will be long-term capital gain or loss if, as of such time, the
holder thereof has held such Shares for more than one year.
 
  The Company's redemption of the Company Rights will be a dividend taxable as
ordinary income (to the extent of the Company's current or accumulated earnings
and profits) to all holders of Shares, and the assignment of such redemption
proceeds by a tendering stockholder to the Purchaser pursuant to the Offer will
constitute an offset to the amount realized by the tendering stockholder
pursuant to the Offer for federal income tax purposes.
 
                                       12

  Withholding. Unless a stockholder complies with certain reporting and/or
certification procedures or is an exempt recipient under applicable provisions
of the Code and Treasury Regulations, such stockholder may be subject to
withholding tax of 31% with respect to payments received pursuant to the Offer
and the Merger. Stockholders should consult their brokers to ensure compliance
with such procedures. Foreign stockholders should consult with their own tax
advisors regarding withholding taxes in general.
 
  THE ABOVE DISCUSSION MAY NOT APPLY TO PARTICULAR CATEGORIES OF HOLDERS OF
SHARES SUBJECT TO SPECIAL TREATMENT UNDER THE CODE, SUCH AS FOREIGN HOLDERS,
QUALIFIED EMPLOYEE BENEFIT PLANS AND HOLDERS WHOSE SHARE WERE ACQUIRED PURSUANT
TO THE EXERCISE OF AN EMPLOYEE STOCK OPTION OR OTHERWISE AS COMPENSATION.
STOCKHOLDERS OF THE COMPANY ARE URGED TO CONSULT THEIR OWN TAX ADVISORS TO
DETERMINE THE SPECIFIC TAX CONSEQUENCES OF THE OFFER AND THE MERGER, INCLUDING
ANY STATE, LOCAL OR OTHER TAX CONSEQUENCES OF THE OFFER AND THE MERGER.
 
  Real Estate Transfer Taxes. The New York State Real Property Transfer Gains
Tax, the New York State Real Estate Transfer Tax and the New York City Real
Property Transfer Tax (collectively, the "Real Estate Transfer Taxes") are
imposed on the transfer or acquisition, directly or indirectly, of controlling
interests in an entity which owns interests in real property located in New
York State or New York City, as the case may be. The Offer and the Merger may
result in the taxable transfer of controlling interests in entities which own
New York State or New York City real property for purposes of the Real Estate
Transfer Taxes. Although any Real Estate Transfer Taxes could be imposed
directly on the stockholders of the Company, the Purchaser and the Company will
complete and file any necessary tax returns, and, as provided in the Merger
Agreement, the Purchaser will pay all Real Estate Transfer Taxes that are
imposed as a result of the Offer and the Merger. Upon receipt of the
consideration for either the Offer or the Merger, each stockholder of the
Company will be deemed to have agreed to be bound by the Real Estate Transfer
Tax returns filed by the Purchaser and the Company.

  7. CERTAIN INFORMATION CONCERNING THE COMPANY. The information concerning the
Company contained in this Offer to Purchase, including financial information,
has been furnished by the Company or has been taken from or based upon publicly
available documents and records on file with the Commission and other public
sources. Neither the Purchaser nor the Dealer Manager assumes any
responsibility for the accuracy or completeness of the information concerning
the Company contained in such documents and records or for any failure by the

marketing operations, natural gas liquids processing, natural gas gathering and
a nonoperating interest in a coalbed methane project in Alabama. The Company's
pipeline business is conducted through Transcontinental Gas Pipe Line
Corporation ("TGPL") and Texas Gas Transmission Corporation ("TXG"). These
companies, which are regulated by the Federal Energy Regulatory Commission (the

Company ("TGMC"). TGMC, through agency agreements, manages all jurisdictional
sales of TGPL and Texas Gas, except for the sale of gas purchased by Texas Gas
under certain contracts, which is auctioned monthly. Jurisdictional sales are
sales made to local distribution customers located, in the case of TGPL, in the
eastern United States and, in the case of Texas Gas, in the midwestern United
States. TGMC also manages all non-jurisdiction sales of Transco Energy
Marketing Company ("TEMCO") and TXG Gas Marketing Company ("TXG Marketing").
TEMCO buys, arranges transportation for, and sells natural gas, primarily in
the eastern and midwestern United States and Gulf Coast region. TXG Marketing
markets natural gas, primarily to customers in the midwestern United States.
The Company's coal business is conducted through Transco Coal Company ("TCC").

  Certain Projected Financial Information. In the course of its discussions
with the Purchaser described in Section 10, the Company provided the Purchaser
and its financial advisors with certain business and financial information
which the Purchaser and the Company believe was not publicly available. Such
information included, among other things, certain financial projections for
1994 through 1998 prepared by management of the Company as a long range plan,
a selected summary of which is set forth below. The Company does not as a
matter of course publicly disclose internal projections as to future revenues,
earnings or financial condition.
 
  The projections do not give effect to the Offer or the Merger and were
predicated on certain assumptions, including the following: (i) increases over
the period in total rate bases for TGPL and TXG from $1.51 billion and $525
million, respectively, for 1994 to $1.68 billion and $540 million,
respectively, for 1998; (ii) a FERC-allowed rate of return for TGPL of 14.81%
for 1994, 14.62% for 1995 and 14.25% for 1996 through 1998 and for TXG of
13.9% for 1994 and 14.25% for 1995 through 1998; (iii) a long-term borrowing
rate of 9% for 1994 through 1997 and 9.5% for 1998; (iv) a prime interest rate
of 7.5% in 1994 and 7.75% from 1995 through 1998; (v) an increase over the
period in nominal crude oil prices and Gulf Coast spot gas prices from $18.00
per barrel and $2.10 per dekatherm respectively, for 1994 to $21.50 per barrel
and $2.45 per dekatherm, respectively, for 1998; (vi) public offerings of
Shares of $150 million at $15.00 per Share and of $170 million at $17.00 per
Share in 1995 and 1997, respectively, with the proceeds being used to retire
debt; and (vii) capital expenditures and investments of $228 million in 1994,
$251 million in 1995, $234 million in 1996, $230 million in 1997 and $209
million in 1998 to be used, among other things, to maintain the existing
pipelines and fund certain pipeline expansion in the Southeast, the Northeast
and the Gulf Coast.

  Except for the Merger Agreement and the Stock Option Agreement and as
otherwise set forth in this Offer to Purchase, none of the Purchaser, or, to
the best knowledge of the Purchaser, any of the persons listed in Schedule I
hereto has any contract, arrangement, understanding or relationship with any

  Sub. Sub is a newly incorporated Delaware corporation organized in connection
with the Merger and has not carried on any activities other than in connection
with the Merger. Sub's principal offices are located at One Williams Center,
Tulsa, Oklahoma 74172. Until immediately prior to the Effective Time it is not
expected that Sub will have any significant assets or liabilities or engage in
activities other than those incident to its formation and capitalization and
the transactions contemplated by the Merger. Due to the fact that Sub is newly
formed and has minimal assets and capitalization, no meaningful financial
information regarding Sub is available.
 
  9. SOURCE AND AMOUNT OF FUNDS. The Purchaser estimates that the total amount
of funds required to acquire the Shares pursuant to the Offer and the Merger
and to pay related fees and expenses will be approximately $460 million. See
Section 16.
 
  The Purchaser plans to obtain the necessary funds from the proceeds of the
WNS Sale. See Section 8. However, since the completion of the WNS Sale could be
following consummation of the Offer, the Purchaser obtained commitments on
December 9, 1994, from Citibank, N.A. ("Citibank"), Bank of America National
Trust and Savings Association, Chemical Bank and Canadian Imperial Bank of
Commerce to implement a Senior Revolving Credit Facility (the "Purchaser Credit
Facility") for up to $1,200,000,000 to finance the acquisition of the Company,
refinance existing debt of the Purchaser, pay transaction costs and provide
working capital for the Purchaser. The term of the Purchaser Credit Facility
will extend to December 31, 1995.
 
  The Purchaser Credit Facility will provide for interest payable at the
Applicable Margin above Citibank's Base Rate or, at the Purchaser's option,
Citibank's Eurodollar Rate. Citibank's "Base Rate" is a fluctuating interest
rate equal to the highest from time to time of (i) the rate of interest
announced publicly by Citibank in New York as its base rate, (ii) 1/2 of 1% per
annum above the latest three-week moving average of secondary market morning
offering rates for three-month certificates of deposit of major U.S. money
market banks, as determined weekly by Citibank and adjusted for the cost of
reserves and estimated insurance assessments from the Federal Deposit Insurance
Corporation, and (iii) a rate equal to 1/2 of 1% per annum above the weighted
average of the rates on overnight Federal funds transactions with members of
the Federal Reserve System arranged by Federal funds brokers, as determined for
any day by Citibank. The "Applicable Margin" means 0% per annum for Base Rate
borrowings and a 0.625% per annum for Eurodollar Rate borrowings based on the
Purchaser's current public debt rating.
 
  All net cash proceeds from the WNS Sale (after payment of amounts then
payable under the U.S. $400,000,000 Credit Agreement dated as of September 2,
1994, between WTG Holdings, Inc., a subsidiary of the Purchaser, and Citibank)
will be applied to the permanent reduction of the Purchaser Credit Facility. No
final decisions have been made concerning the method the Purchaser will employ
to repay such indebtedness
 
                                       19

if the WNS Sale is not completed. Such decisions when made will be based on
the Purchaser's review from time to time of the advisability of particular
actions, as well as on prevailing interest rates and financial and other
economic conditions.
 
  10. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY; THE MERGER AGREEMENT
AND THE STOCK OPTION AGREEMENT; OTHER MATTERS
 
BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY
 
  In July 1992, the Purchaser was contacted by representatives of the Company
to explore the Purchaser's interest in a potential acquisition of the Company.
The Purchaser requested additional business and financial information about
the Company and entered into a confidentiality agreement with respect to the
non-public information that was furnished to it. Following preliminary
discussions, the Purchaser determined not to pursue a transaction with the
Company at that time.
 
  On September 9, 1994, Keith E. Bailey, Chairman, President and Chief
Executive Officer of the Purchaser, at a social occasion with John P.
DesBarres, Chairman, President and Chief Executive Officer of the Company,
made a passing comment about the possibility of their considering a business
combination of their respective companies, the Company to which Mr. DesBarres
did not respond. At an informal meeting on September 30, 1994, Mr. Bailey
advised Mr. DesBarres of the Purchaser's interest in considering a business
coordinate with the Company and sought to determine the Company's interest in
pursuing such discussions. Mr. DesBarres advised Mr. Bailey that the Company
would be willing to consider pursuing discussions with the Purchaser.
 
  On October 10, 1994, the Purchaser and the Company executed a mutual
confidentiality agreement, pursuant to which they agreed to maintain the
confidentiality of non-public information that was received from the other
party. Over the next two months, each company's management and advisors
conducted due diligence investigations of the other party.
 
  At a meeting between Messrs. Bailey and DesBarres on November 23, 1994, Mr.
Bailey proposed that the Purchaser acquire 51% of the Shares for $17.00 per
Share in cash, with the remaining Shares acquired in a merger for (i) .55 of a
share of Purchaser Common Stock and (ii) a contingent value right which would
pay additional cash consideration of up to a maximum of $2.00 per right if the
Purchaser Common Stock did not reach specified trading levels during any
twenty consecutive trading days during a 12-18 month period. Mr. Bailey also
indicated that the Purchaser would require a stock option and certain
termination fees to be paid by the Company in connection with any transaction.
Mr. Bailey also indicated that he would like Mr. DesBarres to become President
and a Director of the Purchaser following the transaction. Mr. DesBarres
responded that he wanted to defer any discussions about his future employment
until after any transaction was finally agreed upon, and that in any event he
needed to consider personal and career issues before making any decision.
 
  On November 26, 1994, Mr. DesBarres, after consulting with the Company's
financial advisor, advised Mr. Bailey that the proposed consideration was
inadequate and that he was postponing the more extensive due diligence
investigations that had been planned to commence on November 27, 1994 until
the financial terms were more fully negotiated. After further discussions
during the following week between Messrs. Bailey and DesBarres and their
respective financial advisors, the Purchaser increased its proposal on
December 2, 1994 to $17.50 per Share in cash for up to 55% of the outstanding
Shares and .6 of a share of Purchaser Common Stock for each remaining Share
acquired in the merger. The Purchaser rejected proposals by the Company's
financial advisors for an adjustable exchange ratio in the merger within a
range or "collar". The Purchaser also continued to demand as part of its
proposal that the Company grant the Purchaser a stock option at $17.50 per
Share for approximately 18% of the outstanding Shares with a $5 per Share cap
on its value and a separate termination fee of $15 million. While Mr.
DesBarres, after informal consultations with other Board members, advised Mr.
Bailey that the proposal would require additional improvement, he agreed to
let the due diligence investigation commence. Later that day, following
further discussions with Mr. DesBarres, and based upon the relative prices of
the Shares and the Purchaser Common Stock on
 
                                      20

December 2, 1994, Mr. Bailey agreed to increase the exchange ratio to .625
assuming that negotiations were successfully completed. The Purchaser's
counsel delivered drafts of the agreements to representatives of the Company
on December 3, 1994.
 
  Over the next few days, the parties continued to negotiate the proposal and
the Purchaser agreed to increase the percentage of Shares acquired for cash to
approximately 60%. In addition, the Purchaser replaced its demand for a $15
million termination fee with a provision for the Company to reimburse the
Purchaser for its actual expenses (up to a maximum of $15 million) upon the
occurrence of certain events, including if the Company terminates the Merger
Agreement to accept a competing bid to acquire the Company.
 
  Representatives of the Purchaser and the Company continued to negotiate the
agreements over the next three days. On December 11, 1994, the Purchaser
agreed to reduce the cap on the value of its option to $2 per option Share and
agreed to the Company's request for the right to cancel the option following
any exercise by the Purchaser for a cash payment not to exceed such cap. On
December 11, 1994, the Boards of Directors of the Purchaser and the Company
approved the Merger Agreement and the Stock Option Agreement. On December 12,
1994, the Merger Agreement and the Stock Option Agreement were executed and
the parties issued a joint press release with respect thereto.
 
THE MERGER AGREEMENT
 
  The following is a summary of the Merger Agreement, a copy of which is filed
as an Exhibit to the Tender Offer Statement on Schedule 14D-1 (the "Schedule
14D-1") filed by the Purchaser with the Commission in connection with the
Offer. Such summary is qualified in its entirety by reference to the Merger
Agreement.
 
  The Offer. The Purchaser has agreed in the Merger Agreement to accept Shares
tendered pursuant to the Offer for payment on the earliest expiration date of
the offer on which the Minimum Condition and the other conditions that are
described in Section 14 hereof are satisfied. The Purchaser has also agreed,
if such conditions are not so satisfied as of any expiration date but subject
to its right under the circumstances described below to terminate the Offer
and the Merger Agreement, to extend such expiration date from time to time
until the earlier of the consummation of the Offer and 90 days following
commencement of the Offer.
 
  Under the Merger Agreement, the Purchaser has expressly reserved the right
to (i) increase the price per Share payable pursuant to the Offer or (ii)
increase on one occasion the number of Shares (and attached Rights) to be
purchased in the Offer; provided, that (x) any increase in the number of
Shares to be purchased which requires an extension of the Offer beyond its
then applicable expiration date in accordance with applicable law must provide
for an increase of at least 4,000,000 Shares and (y) any increase in the
number of Shares sought at a time when the average closing sale prices on the
NYSE for shares of Purchaser Common Stock for the ten trading days immediately
preceding the date of public notice of the increase exceeds $28 may only be
made with the consent of the Company. The Purchaser has agreed in the Merger
Agreement that, without the prior written consent of the Company, the
Purchaser will not (i) decrease the price per Share payable pursuant to the
Offer, (ii) decrease or (other than as described in the immediately preceding
sentence) increase the number of Shares to be purchased in the Offer, (iii)
change the form of consideration payable in the Offer, (iv) add to or change
the conditions of the Offer, (v) change or waive the Minimum Condition or (vi)
make any other change in the terms or conditions of the Offer which is adverse
to the holders of the Shares.
 
  Company Board Representation by the Purchaser Following the Offer. The
Company has agreed in the Merger Agreement that, effective upon payment by the
Purchaser for the Shares accepted for payment pursuant to the Offer, the
Purchaser will be entitled to designate two directors to the Company Board and
the Company will take all necessary action to cause the Purchaser's designees
to be elected or appointed to the Company Board including, without limitation,
increasing the number of directors or seeking and accepting resignations of
incumbent directors. In such connection, the Purchaser has agreed that (i) its
designees will abstain from any action taken by the Company to amend or
terminate the Merger Agreement or waive any action by the Purchaser, which
actions will be effective with the approval of a majority of the remaining
directors, and (ii) it will not effect any other changes to the Company Board
prior to the Effective Time.
 
                                      21

  The Merger. The Merger Agreement provides that, upon the terms and subject to
the conditions thereof, at the Effective Time, Sub will be merged with and into
the Company in accordance with Delaware Law. As a result of the Merger, the
separate corporate existence of Sub will cease and the Company will continue as
the Surviving Corporation.
 
  Upon consummation of the Merger each issued and then outstanding Share (other
than Retired or Dissenting Shares) will be converted into the right to receive
the Per Share Cash Amount, if any, and a fraction of a share of Purchaser
Common Stock equal to the Conversion Number, together with a number of attached
Purchaser Rights equal to the Conversion Number divided by 2.
 
  In addition, also at the Effective Time, each issued and outstanding share of
Company $4.75 Preferred Stock and each issued and outstanding share of Company
$3.50 Preferred Stock (in each case other than shares that are owned by the
Company as treasury stock, or owned by the Purchaser or any wholly-owned
subsidiary of the Purchaser, or, to the extent appraisal rights are available
to such holders, dissenting shares) will be converted into the right to receive
one share of Purchaser $4.75 Preferred Stock or Purchaser $3.50 Preferred
Stock, respectively.
 
  Pursuant to the Merger Agreement, the Company shall call and hold a meeting
of its stockholders (the "Stockholders' Meeting") as soon as practicable
following consummation of the Offer for the purpose of considering and taking
action on the Merger Agreement and the transactions contemplated thereby. The
Merger Agreement requires the Company, through its Board of Directors, to
recommend to its stockholders approval of the Merger and related matters;
provided, however, that nothing contained in the Merger Agreement will require
the Company Board to take any action or refrain from taking any action which
the Board determines in good faith with the advice of counsel could reasonably
be expected to result in a breach of its fiduciary duties under applicable law.
The Purchaser has agreed to cause all Shares acquired by it pursuant to the
Offer or the Stock Option Agreement to be represented at the Stockholders'
Meeting and to be voted in favor of approval and adoption of the Merger
Agreement and the Merger. If the Purchaser holds at least a majority of the
Shares outstanding on the record date for establishing holders of Shares
entitled to vote at the Stockholders' Meeting, the Purchaser will have
sufficient voting power to approve the Merger, even if no other stockholder of
the Company votes in favor of the Merger.
 
  The Merger Agreement provides that the Company and the Purchaser, will each
use its reasonable best efforts to take, or cause to be taken, all actions, and
to do, or cause to be done, in each case consistent with the fiduciary duties
of their respective Boards of Directors as advised by counsel, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by the Merger
Agreement and the Stock Option Agreement, including (i) the prompt preparation
and filing with the Commission of the Purchaser's registration statement on
Form S-4 (the "S-4") and the Company's proxy statement (the "Proxy Statement"),
(ii) such actions as may be required to have the S-4 declared effective under
the Securities Act and the Proxy Statement cleared by the Commission, in each
case as promptly as practicable, and (iii) such actions as may be required to
be taken under applicable state securities or blue sky laws in connection with
the issuance of shares of Purchaser Common Stock (and the attached Purchaser
Rights) and Purchaser New Preferred Stock pursuant to the Merger.
 
  Pursuant to the Merger Agreement, the Purchaser has agreed to use its
reasonable best efforts to list the Purchaser Common Stock (and attached
Purchaser Rights) to be issued in the Merger on the NYSE and the Purchaser
$4.75 Preferred Stock to be issued in the Merger to be listed on the NYSE or
quoted on the NASDAQ (as hereinafter defined) National Market System, in each
case not later than the Effective Time.
 
  The Merger Agreement provides that, at the Effective Time, the Second
Restated Certificate of Incorporation of the Company, as amended and restated
substantially in the form set forth in an exhibit to the Merger Agreement, will
be the Certificate of Incorporation of the Surviving Corporation. The Merger
Agreement also provides that the By-laws of Sub, as in effect immediately prior
to the Effective Time, will be the By-laws of the Surviving Corporation until
amended in accordance with applicable law.
 
                                       22

  Representations and Warranties. The Merger Agreement contains various
customary representations and warranties of the parties thereto including
representations by the Company and the Purchaser as to the absence of certain
changes or events concerning their respective businesses, compliance with law,
litigation and other matters.
 
  Certain Restrictions on Business Pending the Merger. The Company has agreed
that prior to the Effective Time, unless otherwise consented to in writing by
the Purchaser, the Company will, and will cause each of its subsidiaries to,
conduct its operations only in the ordinary and usual course of business
consistent with past practice and will use all reasonable efforts, and will
cause each of its subsidiaries to use all reasonable efforts, to preserve
intact its present business organization, keep available the services of its
present officers and employees and preserve its relationships with licensors,

dealings with it, in each case in all material respects. Without limiting the
generality of the foregoing, and except as otherwise expressly provided in the
Merger Agreement, the Company will not, and will not permit any of the

Company pursuant to collective bargaining agreements entered into in the
ordinary course of business consistent with past practice, and (d) the
consummation of the pending merger of the Company's Tran$tock Employee Stock

the compensation or fringe benefits payable or to become payable to its
directors, officers or employees
 
                                      23

required by any existing plan or arrangement (including, the granting of, or

or incorrect in any material respect.
 
  The Purchaser has agreed that it will not, and will not permit any of its
subsidiaries to, prior to the Effective Time, without the prior written consent
of the Company (which will not be unreasonably withheld): (i) adopt any
amendment to its certificate of incorporation or by-laws or comparable
organizational documents; (ii) except for issuances of capital stock of the
Purchaser's subsidiaries to the Purchaser or a wholly owned subsidiary of the

additional shares of capital stock of any class, or securities convertible into
capital stock of any class, or any rights, warrants or options to acquire any

(under which approximately $406.8 million and $6.4 million, respectively, of
purchases had been made as of December 12, 1994) and in connection with the

adjust, split, combine, subdivide, reclassify or redeem, purchase or otherwise

its capital stock; (v) except as set forth in the Merger Agreement, acquire,

agree in writing or otherwise
 
                                       24

to take any of the foregoing actions or any action which would make any
representation or warranty in the Merger Agreement untrue or incorrect in any
material respect.
 
  Acquisition Transactions. Under the Merger Agreement, the Company has agreed,
subject to the matters described in the immediately succeeding paragraph, that
it will not, nor will it permit its officers, directors, subsidiaries,
representatives or agents, directly or indirectly, to do any of the following:
(i) negotiate, undertake, authorize, propose or enter into, either as the
proposed surviving, merged, acquiring or acquired corporation, any transaction
(other than the Offer and the Merger) involving any disposition or other change
of ownership of a substantial portion of the Company's stock or assets (an
"Acquisition Transaction"); (ii) solicit or initiate the submission of a
proposal or offer in respect of, or engage in negotiations concerning, an
Acquisition Transaction; or (iii) furnish or cause to be furnished to any
corporation, partnership, person or other entity or group (other than the other
party and its representatives) (a "Person") any non-public information
concerning the business, operations, properties or assets of the Company in
connection with an Acquisition Transaction provided, nothing herein will
prohibit the Company Board from taking and disclosing to the Company's
stockholders a position with respect to a tender offer pursuant to Rules 14d-9
and 14e-2 promulgated under the Exchange Act. The Company has also agreed to
inform the Purchaser by telephone within two business days of its receipt of
any proposal or bid (including the terms thereof and the Person making such
proposal or bid) in respect of any Acquisition Transaction.
 
  Notwithstanding the restriction described in the immediately preceding
paragraph, the Company and its officers, directors, subsidiaries,
representatives and agents may engage in discussions or negotiations with, and
may furnish information to, a third party who, or representatives of a third
party who, makes a written proposal with respect to an Acquisition Transaction
if (i) the Company Board determines in good faith after consultation with its
financial advisors that such proposal may reasonably be expected to result in a
transaction that is financially superior to the transactions contemplated by
the Merger Agreement, or (ii) the Company Board determines in good faith with
advice of outside counsel that failure to do so could reasonably be expected to
result in a breach of its fiduciary duties under applicable law. If the Company
accepts a proposal for or otherwise engages in any Acquisition Transaction
(other than the Offer or the Merger), it will promptly pay to the Purchaser in
reimbursement for the Purchaser's expenses an amount in cash (not to exceed
$15,000,000) equal to the aggregate amount of the Purchaser's documented out-
of-pocket expenses incurred in connection with pursuing the transactions
contemplated by the Merger Agreement as certified in good faith by the
Purchaser and with reasonable detail.
 
  Indemnification and Directors' and Officers' Insurance. The Purchaser and the
Company have agreed in the Merger Agreement that the Certificate of
Incorporation of the Surviving Corporation or any successor by merger will
contain the provisions with respect to indemnification which are set forth in
the form of Third Restated Certificate of Incorporation of the Company included
as an exhibit to the Merger Agreement, which provisions will not be amended,
repealed or otherwise modified for a period of six years after the Effective
Time provided that, in the event any claim is asserted or made within such six-
year period, all rights to indemnification in respect of any such claim will
continue until disposition of any and all such claims. The Merger Agreement
further provides that, for a period of not less than six years after the
Effective Time, the Purchaser will, or will cause the Surviving Corporation to
provide, directors' and officers' liability insurance having substantially the
same terms and conditions and providing at least the same coverage and amounts
as the directors' and officers' liability insurance that is maintained by the
Company at the Effective Time for all directors and officers of the Company and
its subsidiaries who served as such at, or within one year prior to, the
Effective Time. However, the Purchaser will not be required to pay an annual
premium for such insurance in excess of the last annual premium paid by the
Company prior to December 12, 1994 (but in such case will purchase as much
coverage as possible for such amount).
 
  Redemption of Company Rights. Under the Merger Agreement, the Company has
agreed to redeem the Company Rights effective immediately prior to the
Purchaser's acceptance for payment of Shares pursuant to the Offer and will not
otherwise redeem the Company Rights, or amend or terminate the Company Rights
Agreement, unless in each such case the Company Board determines in good faith
with the
 
                                       25

advice of outside counsel that complying with such covenant could reasonably be
expected to result in a breach of its fiduciary duties under applicable law.
The Company has agreed that the Offer will provide, and require that tendering
stockholders confirm, that the Purchaser will be entitled to receive and retain
the amounts paid in redemption of all Company Rights attached to Shares
acquired pursuant to the Offer.
 
  Company Benefit Plans. The Merger Agreement provides that, except as
otherwise agreed with individual option holders, at the Effective Time, (i)
each then outstanding option to purchase Shares (a "Company Stock Option")
under the Company's stock incentive plans (the "Company Plans"), whether vested
or unvested, will become fully exercisable and vested, (ii) each Company Stock
Option which is then outstanding will be cancelled and (iii) in consideration
of such cancellation, at the election of the option holder, which may be
allocated to either or both elections, (a) the Company will pay to such holders
of Company Stock Options an amount in respect thereof equal to the product of
(x) the excess, if any, of the Offer Price over the respective exercise price
thereof and (y) the number of Shares subject thereto, respectively, or (b) the
Purchaser will issue an option as described below (a "Replacement Option").
 
  The Replacement Option with respect to each Company Stock Option, the
exercise price for which exceeds $35 per Share, will be an option to acquire,
on the same terms and conditions as were applicable under such Company Stock
Option (except that it will be subject to a vesting period ending on the first
anniversary of the Effective Time), (i) an amount in cash equal to the product
of $10.50 times the number of Shares purchasable under such Company Stock
Option immediately prior to the Effective Time and (ii) the number of shares of
Purchaser Common Stock equal to the product of .25 and the number of Shares
purchasable under such Company Stock Option immediately prior to the Effective
Time. The Purchaser will cause such options to continue to vest and to remain
exercisable following the termination of the option holder's employment with
the Purchaser and its affiliates in accordance with its past practice relative
to the Purchaser's current employees; provided, that with respect to any
employee of the Company or its subsidiaries at the Effective Time (a "Current
Employee") whose employment with the Purchaser or its affiliates is terminated
other than voluntarily by the employee or involuntarily for cause or as a
result of retirement, the Purchaser will cause such options to continue to vest
until the earlier of (i) six months following such termination and (ii) the end
of the term of such option, as in effect immediately before such termination.
All of the foregoing payments and issuances of shares in connection with such
cancellations will be made either net of applicable withholding taxes or upon
payment of required withholding taxes by the option holders.
 
  The Replacement Option with respect to each Company Stock Option, the
exercise price for which is less than or equal to $35 per Share, will be an
option to acquire, on the same terms and conditions as were applicable under
such Company Stock Option, the same number of shares of Purchaser Common Stock
as the holder of such Company Stock Option would have been entitled to receive
pursuant to the Merger had such holder exercised such option in full
immediately prior to the Effective Time (not taking into account whether or not
such option was in fact exercisable), at a price per share equal to (i) the
aggregate exercise price for the Shares deemed otherwise purchasable pursuant
to such Company Stock Option divided by (ii) the number of full shares of
Purchaser Common Stock deemed purchasable pursuant to such Company Stock
Option. All of the foregoing payments and issuances of shares in connection
with such cancellations will be made either net of applicable withholding taxes
or upon payment of required withholding taxes by the optionholders.
 
  The Merger Agreement provides that the Company Plans will generally terminate
as of the Effective Time and the provisions in any other plan, program or
arrangement, providing for the issuance or grant of any other interest in
respect of the capital stock of the Company or any of its subsidiaries will be
deleted as of the Effective Time. The Merger Agreement also provides that the
Company's other employee benefit plans, programs and policies other than salary
(collectively, the "Employee Benefit Plans") in effect at the date of the
Merger Agreement will, to the extent practicable, remain in effect until
otherwise determined after the Effective Time and, to the extent such Employee
Benefit Plans are not continued, the Purchaser will maintain Employee Benefit
Plans with respect to employees of the Company and its subsidiaries which are
no less favorable, in the aggregate, than the least favorable of: (i) those
Employee Benefit Plans covering employees
 
                                       26

of the Purchaser from time to time; (ii) those Employee Benefit Plans of the
Company and its Subsidiaries that are in effect on the date of this Agreement
other than the Tran$tock Plan; or (iii) Employee Benefit Plans that are
reasonably competitive with respect to the industry in which the employer of
the affected employees competes; provided, that in any event, until the first
anniversary of the Effective Time, the Surviving Corporation will provide
Current Employees with Employee Benefit Plans, other than a nonqualified,
unfunded plan maintained primarily to provide deferred compensation benefits to
a select group of "management or highly compensated employees" within the
meaning of Sections 201, 301, and 401 of ERISA, that are no less favorable in
the aggregate than those provided to Current Employees by the Company and for
its Subsidiaries immediately before the Effective Time. In the case of benefit
plans which are continued and under which the employees' interests are based
upon Company Common Stock, such interests will be based on Parent Common Stock
in an equitable manner.
 
  In the Merger Agreement the Purchaser has agreed to cause the Surviving
Corporation to (i) honor (a) in accordance with their terms all individual
employment, severance, termination and indemnification agreements which by
their express terms may not be unilaterally amended by the Company or any of
its subsidiaries and (b) without modification all other specified employee
severance plans, policies, employment and severance agreements and
indemnification arrangements of the Company or any of its subsidiaries as such
plans, policies, or agreements were in effect on the date of the Merger
Agreement through the later of (x) December 31, 1995, (y) the termination date
specified in such document or (z) the date agreed to by the Purchaser and the
Company, (ii) waive any limitations regarding pre-existing conditions of
Current Employees and their eligible dependents under any welfare or other
employee benefit plans of the Purchaser and its affiliates in which they
participate after the Effective Time (except to the extent that such
limitations would have applied under the analogous plan of the Company and its
subsidiaries immediately before the Effective Time), (iii) for all purposes
under the post-retirement welfare benefit plans and policies of the Purchaser
and its affiliates, treat Current Employees in the same manner as similarly
situated employees of the Purchaser who were hired by the Purchaser before
January 1, 1992 in accordance with the terms of such plans and policies as then
in effect, as any such plans and policies are modified by the Purchaser or such
affiliates from time to time, and (iv) for all other purposes under all
Employee Benefit Plans applicable to employees of the Company and its
subsidiaries, treat all service with the Company or any of its subsidiaries by
Current Employees before the Closing as service with the Purchaser and its
subsidiaries, except to the extent such treatment would result in duplication
of benefits or would violate applicable law.
 
  The Merger Agreement also provides that, except as otherwise agreed with
individual restricted stockholders, at the Effective Time, each Share which
immediately prior to the Effective Time was subject to restrictions on
transfer, whether vested or unvested, will become fully vested and freely
transferable and will be exchanged for unrestricted shares of Purchaser Common
Stock (with attached Purchaser Rights) pursuant to the Merger Agreement.
 
  Other Matters. In the Merger Agreement, the Company has agreed to declare a
dividend on each share of the Company Preferred Stock to holders of record of
such shares as of the close of the business day next preceding the Effective
Time in an amount equal to the product of (i) a fraction, (x) the numerator of
which equals the number of days between the payment date with respect to the
most recent regular dividend paid by the Company and the Effective Time and (y)
the denominator of which equals 91 and (ii) the amount of the regular quarterly
dividend paid by the Company on the relevant series of Company Preferred Stock.
The Company has also agreed (i) to promptly seek agreement, on terms reasonably
acceptable to the Purchaser, of the banks party to the Company's revolving
credit and letter of credit reimbursement agreements to (a) amend such
agreements to provide that the execution by the Company of the Merger Agreement
and the Stock Option Agreement and the purchase of Shares pursuant to the Offer
or the Stock Option Agreement do not constitute an event permitting the banks
which are parties thereto to accelerate the amounts outstanding under such
agreements or establish cash collateral accounts (the "Bank Consents"), (b)
amend such agreements to permit the consummation of the Merger, and (c) waive
the interest rate increase otherwise applicable by reason of such events, (ii)
to select the latest notice and repurchase dates permitted under the
 
                                       27

indenture governing the Company Notes in respect of the "change of control"
effected by consummation of the Offer and (iii) in the event that such
repurchase date occurs prior to the Merger, to cooperate with the Purchaser in
arranging financing on terms reasonably acceptable to the Purchaser to finance
any required repurchase of Company Notes.
 
  Conditions to the Merger. The obligations of Purchaser and the Company to
consummate the Merger are subject to the satisfaction or, where legally
permissible, waiver of various conditions, including that (i) the Purchaser has
accepted for purchase and paid for Shares pursuant to the Offer; provided, that
this condition will be deemed satisfied with respect to the Company if the
Purchaser fails to purchase Shares pursuant to the Offer in violation of the
terms of the Offer; (ii) the Merger Agreement (insofar as it relates to the
Merger) and the Merger have been approved and adopted by the affirmative vote
of the holders of Shares entitled to cast at least a majority of the total
number of votes entitled to be cast by holders of Shares; (iii) any waiting
period under the HSR Act applicable to the Merger has expired or been
terminated; (iv) the S-4 has become effective under the Securities Act and is
not the subject of any stop order or proceeding seeking a stop order and the
Purchaser has received all material state securities or blue sky permits and
other authorizations necessary to issue the shares of Purchaser Common Stock
(and attached Purchaser Rights) and Purchaser New Preferred Stock pursuant to
the Merger Agreement; (v) no temporary restraining order, preliminary or
permanent injunction or other order issued by any court of competent
jurisdiction or other legal restraint or prohibition preventing the
consummation of the Merger is in effect (each party agreeing to use all
reasonable efforts to have any such order reversed or injunction lifted); (vi)
the Purchaser Common Stock (and the attached Purchaser Rights) to be issued in
the Merger has been approved for listing on the NYSE, subject to official
notice of issuance; and (vii) no action, suit or proceeding by any governmental
entity before any court or governmental or regulatory authority is pending
against the Company, the Purchaser or Sub or any of their subsidiaries
challenging the validity or legality of the transactions contemplated by the
Merger Agreement other than actions, suits or proceedings as to which the
Purchaser had actual knowledge at the time of acceptance for payment of Shares
pursuant to the Offer or which, in the reasonable opinion of counsel to the
party asserting such condition, do not have a substantial likelihood of
resulting in a material adverse judgment.
 
  The obligations of the Purchaser and Sub to effect the Merger and the
transactions contemplated by the Merger Agreement are further subject to the
Company not having failed to perform its material obligations required to be
performed by it under the covenant described above relating to restrictions on
business pending the Merger at or prior to the closing date of the Merger,
other than any such failures to perform as to which the Purchaser had actual
knowledge at the time of acceptance for payment of Shares pursuant to the
Offer. The obligation of the Company to effect the Merger is subject to the
Purchaser and Sub not having failed to perform their material obligations
required to be performed by them under the covenant described above relating to
restrictions on business pending the Merger at or prior to the closing date of
the Merger, other than such failures to perform as to which the Company had
actual knowledge at the time of acceptance of Payment for Shares pursuant to
the Offer.
 
  Termination; Fees and Expenses. The Merger Agreement may be terminated at any
time prior to the Effective Time, whether before or after approval of the
Merger Agreement and the Merger by the stockholders of the Company; (i) by
mutual consent of the Purchaser and the Company by action of their respective
Boards of Directors (with any members of the Company Board who may hereafter be
designated by the Purchaser abstaining); (ii) by the Company if (a) the Offer
expires or is terminated without any Shares being purchased thereunder, or (b)
the Purchaser fails to purchase validly tendered Shares in violation of the
terms and conditions of the Offer or the Merger Agreement; (iii) by the
Purchaser if, due to an occurrence which has made it reasonably impracticable
to satisfy any of the conditions of the Offer set forth in Section 14 hereto at
any time prior to the 90th day following the commencement of the Offer, the
Purchaser (a) terminates the Offer or allows the Offer to expire without the
purchase of any Shares thereunder, unless such termination or expiration has
been caused by or resulted from the failure of the Purchaser to perform in any
material respect any of its covenants and agreements contained in the Merger
Agreement or the Offer, or (b) fails to pay for Shares pursuant to the Offer
within 90 days after the date hereof, unless such failure to pay for such
shares is caused by or results from the failure of the Purchaser to perform in
any material respect
 
                                       28

any of its covenants or agreements contained in the Merger Agreement or the
Offer; (iv) by either the Purchaser or the Company if the Merger is not
consummated before June 30, 1995 despite the good faith effort of such party to
effect such consummation (unless solely by reason of the conditions relating to
the absence of certain injunctions, restraining orders or litigation (in which
case, if such litigation, restraining order or litigation was in existence at
the time of consummation of the Offer, such date will be September 30, 1995) or
the failure to so consummate the Merger by such date is due to the action or
failure to act of the party seeking to terminate the Merger Agreement, which
action or failure to act constitutes a breach of the Merger Agreement); (v) by
either the Purchaser or the Company if any court of competent jurisdiction has
issued an injunction permanently restraining, enjoining or otherwise
prohibiting the consummation of the Offer or the Merger, which injunction has
become final and non-appealable; (vi) prior to the expiration of the Offer, by
the Purchaser if the Company rescinds its redemption of the Company Rights and
all other conditions to consummation of the Offer are satisfied, or the Company
Board withdraws, amends or modifies in a manner adverse to the Purchaser its
favorable recommendation of the Offer or the Merger or promulgates any
recommendation with respect to an Acquisition Transaction (including a
determination to take no position) other than a recommendation to reject such
Acquisition Transaction; or (vii) prior to the expiration of the Offer, by the
Company if (a) (x) any of the representations and warranties of the Purchaser
contained in the Merger Agreement were incorrect in any material respect when
made or have since become, and at the time of termination remain, incorrect in
any material respect, or (y) there has been a material breach on the part of
the Purchaser in the covenants of the Purchaser set forth herein, or any
failure on the part of the Purchaser to comply with its material obligations
hereunder, or any other events or circumstances have occurred, such that, in
any such case, the Purchaser could not satisfy on or prior to June 30, 1995,
any of the conditions to the Company's obligations to effect the Merger, or (b)
the Company receives a written offer with respect to an Acquisition Transaction
and the Company Board, after consulting with its outside counsel and financial
advisor, determines in good faith that such Acquisition Transaction is more
favorable to the Company's stockholders than the transactions contemplated by
the Merger Agreement and, not later than the time of such termination, the
Company has paid the expense reimbursement described above.
 
  In the event of termination of the Merger Agreement by either the Purchaser
or the Company, the Merger Agreement will become void and there will be no
liability or obligation on the part of the Purchaser, Sub or the Company or
their respective officers or directors other than under certain provisions of
the Merger Agreement relating to confidential treatment of non-public
information and the payment of fees and expenses, except to the extent such
termination results from the willful breach by a party of its covenants and
agreements in the Merger Agreement. Under the Merger Agreement, all costs and
expenses, including, without limitation, fees and disbursements of counsel,
financial advisors and accountants, incurred by the Purchaser and the Company
will be borne solely and entirely by the party which has incurred such costs
and expenses, other than as described above with respect to reimbursement by
the Company of expenses of the Purchaser under certain circumstances.
 
  Amendment and Waiver. Subject to applicable law, the Merger Agreement may be
amended by action taken by or on behalf of the respective Boards of Directors
of the Purchaser or the Company at any time prior to the Effective Time. After
approval of the Merger by the stockholders of the Company, no amendment which
under applicable law may not be made without the approval of the stockholders
of the Company, may be made without such approval. At any time prior to the
Effective Time, either the Company or the Purchaser may (i) extend the time for
the performance of any of the obligations or other acts of the other party,
(ii) waive any inaccuracies in the representation and warranties of the other
party contained in the Merger Agreement or in any document delivered pursuant
thereto and (iii) waive compliance by the other party with any of the
agreements or conditions contained therein, provided, that any representatives
of the Purchaser on the Company Board will abstain from any such action to be
taken by the Company.
 
THE STOCK OPTION AGREEMENT
 
  The following is a summary of the Stock Option Agreement. A copy of the Stock
Option Agreement is filed as an Exhibit to the Schedule l4D-1. Such summary is
qualified in its entirety by reference to the Stock Option Agreement.
 
                                       29

  The Option. Pursuant to the Stock Option Agreement, the Company granted to
the Purchaser the option (the "Option") to purchase, upon the terms and subject
to the conditions provided for therein, to 7,500,000 Shares (the "Option
Shares") at an exercise price of $17.50 per share (the "Option Purchase
Price"). If not sooner exercised, the Option will expire fifteen business days
following the termination of the Merger Agreement.
 
  Exercise of the Option. Purchaser may exercise the Option, in whole or in
part, at any time and from time to time following the occurrence of any of the
following events (each a "Triggering Event"): (i) if the Company accepts a
proposal for or otherwise engages in any Acquisition Transaction other than the
Offer or the Merger; (ii) if the Company Board withdraws, amends or modifies in
a manner adverse to the Purchaser its favorable recommendation of the Offer or
the Merger; or (iii) (a) if any person publicly proposes an Acquisition
Transaction and (b) the Offer has expired in accordance with its terms and the
Merger Agreement and the Minimum Condition fails to be satisfied; provided,
however, that no Triggering Event will occur if the Purchaser is in material
breach of the Merger Agreement. No Triggering Event has occurred as of the date
of this Offer to Purchase.
 
  In the event that the Purchaser acquires any Option Shares and within one
year following the date of purchase disposes of such shares (other than to a
wholly owned subsidiary of the Purchaser) through a sale, exchange, transfer,
merger or otherwise, for an amount per share which exceeds the Option Purchase
Price by more than $2.00 (the "Option Cap"), the Purchaser will promptly return
to the Company the amount of such excess and thereby effect an upward
adjustment to the Option Purchase Price. The Purchaser will not sell or
otherwise dispose of Option Shares except in compliance with the Securities Act
and any applicable state securities law.
 
  All payments made by the Purchaser to the Company in connection with the
Option may be made, at the option of the Purchaser, either (a) by wire transfer
or (b) by a certified or bank check or checks, in each case in immediately
available funds.
 
  Cancellation Rights. At any time the Option is exercisable, the Purchaser
will have the right, upon prior written notice (a "Purchaser Cash-out Notice")
to the Company specifying the date of the closing (the "Cancellation Closing")
thereof (which date will not be earlier than ten business days nor later than
twenty business days after the receipt by the Company of such Purchaser Cash-
out Notice), to cause the Company to pay to the Purchaser, in consideration for
the cancellation of all or that part of the Option to be cancelled, an
aggregate cash cancellation price (the "Cancellation Price") equal to the
product of (i) the number of Shares as to which the Option is to be cancelled,
multiplied by (ii) the excess (but in no event more than the Option Cap) of (x)
the Applicable Price (as defined below) over (y) the Option Purchase Price.
 
  At any time after the Company receives an Exercise Notice pursuant to the
Stock Option Agreement, the Company will have the right, upon prior written
notice (a "Company Cash-out Notice" and, together with any Purchaser Cash-out
Notice, a "Cash-out Notice") to the Purchaser not later than two business days
prior to the applicable closing, specifying the date of the Cancellation
Closing thereof (which will not be earlier than five business days nor later
than fifteen business days after the receipt by the Purchaser of the applicable
Company Cash-out Notice), to pay to the Purchaser in consideration for the
cancellation of all or that part of the Option subject to such Exercise Notice,
in lieu of delivering Option Shares, the Cancellation Price with respect to the
Option Shares subject to such Exercise Notice.
 
  The "Applicable Price" will mean the average of the high and low sales prices
(but in no event less than $17.50) of the Shares as quoted on the NYSE, or if
not so quoted on the NYSE, then the average of the high and low sales prices on
the principal national securities exchange is which the Shares are then listed,
and if not so listed on any national securities exchange, then the average of
the high and low bid prices per Share as quoted on the NASDAQ, on the day prior
to the date of the applicable Purchaser Cash-out Notice or the applicable
Exercise Notice, as the case may be (the "Measurement Date"); provided,
however, that if any person has entered into an agreement with the Company for
an Acquisition Transaction, or an Acquisition
 
                                       30

Transaction has otherwise been proposed, prior to the delivery of the
applicable Cash-out Notice, the Applicable Price shall mean the average
consideration proposed to be payable per outstanding Share pursuant to such
Acquisition Transaction (or, if there is more than one such Acquisition
Transaction, pursuant to the Acquisition Transaction which yields the greater
average consideration) valued as of the Measurement Date (with any non-
marketable securities included in such consideration being valued at the fair
market value per share of such securities with such fair market value to be
determined in good faith by an independent investment banking firm selected by
the Company and the Purchaser).
 
OTHER MATTERS
 
  Section 203 of the Delaware Law. As a Delaware corporation, the Company is
subject to Section 203 ("Section 203") of the Delaware Law. Section 203 would
prevent an "Interested Stockholder" (defined as a person beneficially owning
15% or more of a corporation's voting stock) from engaging in a "Business
Combination" (as defined in Section 203) with a Delaware corporation for three
years following the date such person became an Interested Stockholder unless:
(i) before such person became an Interested Stockholder, the board of directors
of the corporation approved the transaction in which such person became an
Interested Stockholder or approved the Business Combination, (ii) upon
consummation of the transaction which resulted in such person becoming an
Interested Stockholder, the Interested Stockholder owned at least 85% of the
voting stock of the corporation outstanding at the time the transaction
commenced (excluding stock held by directors who are also officers and employee
stock ownership plans that do not provide for confidential voting by plan
participants), or (iii) following the transaction in which such person became
an Interested Stockholder, the Business Combination is (x) approved by the
board of directors of the corporation and (y) authorized at a meeting of
stockholders by the affirmative vote of the holders of 66 2/3% of the
outstanding voting stock of the corporation not owned by the Interested
Stockholder. In accordance with the provisions of Section 203, the Company
Board has approved the transactions contemplated by the Merger Agreement and
the Stock Option Agreement, thereby exempting such transactions from such
provisions.
 
  Article Eighth of the Company's Restated Certificate of Incorporation. Under
Article Eighth of the Company's Second Restated Certificate of Incorporation,
certain extraordinary transactions require the prior approval of at least 80%
of the directors then in office or the vote of at least 80% of the outstanding
stock of the Company entitled to vote thereon or compliance with specified
procedural requirements. In accordance with Article Eighth, the Company Board
of Directors by a vote of not less than 80% of the directors then in office
approved the transactions contemplated by the Merger Agreement and the Stock
Option Agreement, thereby exempting such transactions from such provisions.
 
  Redemption by Holders of Company and Subsidiary Preferred Stock. The
Certificates of Designation, Preferences and Rights of the Company $4.75
Preferred Stock and the Company $3.50 Preferred Stock provide that in the event
(i) any person is or becomes the owner of 30% or more of the outstanding common
stock of the Company or (ii) individuals who constitute the Continuing
Directors (as defined therein) cease for any reason to constitute at least a
majority of the Company Board (each a "Change of Control"), each holder of such
preferred stock shall have the right, at the holder's option, to require the
Company to redeem all or any number of such holder's shares, unless such Change
of Control has been approved by the Continuing Directors prior to or within 21
days after the date on which such Change in Control shall have occurred. At its
meeting on December 11, 1994, the Company Board approved the transactions
contemplated by the Merger Agreement and the Stock Option Agreement such that
the redemption rights will not be triggered by such transactions.
 
  The Certificate of Designation, Preferences and Rights of TGPL's Cumulative
Preferred Stock, $8.75 Series provides that in the event (x) (i) any person is
or becomes the owner of 30% or more of the outstanding common stock or (ii)
individuals who constitute the Continuing Directors (as defined therein) cease
for any reason to constitute at least a majority of the Company Board (each a
"Change of Control") and (y) the prevailing credit ratings of TGPL's senior
debt securities is reduced below investment grade on any date within 90 days
following a Change in Control as a result thereof, each holder of such
preferred stock shall
 
                                       31

have the right, at the holder's option, to require TGPL to redeem all or any
number of such holder's shares of such preferred stock, unless such Change of
Control has been approved by the Continuing Directors prior to or within 21
days after the date on which such Change in Control has occurred. At its
meeting on December 11, 1994, the Company Board approved the transactions
contemplated by the Merger Agreement and the Stock Option Agreement, and the
Board of Directors of TGPL will act by written consent to approve such
transactions, such that the redemption rights will not be triggered by such
transactions.
 
  The Company Rights Agreement. At its meeting on December 11, 1994, the
Company Board approved the deferral of the Distribution Date, as defined in the
Rights Agreement, with the effect that none of the transactions contemplated by
the Merger Agreement or the Stock Option Agreement will result in a
Distribution Date, other than an exercise of the Stock Option Agreement
following which the Purchaser beneficially owns 20% or more of the outstanding
Shares. In addition, pursuant to the Merger Agreement, the Company has agreed
to redeem all outstanding Company Rights prior to the Purchaser's acceptance
for payment of Shares pursuant to the Offer, at a redemption price of $.05 per
Company Right, and will not otherwise redeem the Company Rights or amend or
terminate the Company Rights Agreement, unless in each such case the Company
Board determines in good faith with the advice of outside counsel that failure
to do so could reasonably be expected to result in a breach of its fiduciary
duties under applicable law. The Company agreed in the Merger Agreement that
the Offer will provide, and require that tendering stockholders confirm, that
the Purchaser will be entitled to receive and retain the amounts paid in
redemption of all Company Rights attached to Shares acquired pursuant to the
Offer.
 
  11. PURPOSE OF THE OFFER; PLANS FOR THE COMPANY AFTER THE OFFER AND THE
MERGER.
 
  Purpose of the Offer. The purpose of the Offer and the Merger is for the
Purchaser to acquire control of, and ultimately the entire equity interest in,
the Company. The purpose of the Merger is for the Purchaser to acquire all
Shares not purchased pursuant to the Offer. Upon consummation of the Merger,
the separate corporate existence of Sub shall cease, and the Company will
continue as the surviving corporation and a wholly-owned subsidiary of the
Purchaser. The Offer is being made pursuant to the Merger Agreement.
 
  Under Delaware Law, the approval of the Board and the affirmative vote of the
holders of a majority of the outstanding Shares is required to approve and
adopt the Merger Agreement and the transactions contemplated thereby, including
the Merger. The Company Board has unanimously (with one director absent)
approved and adopted the Merger Agreement and the transactions contemplated
thereby. Thus, the only remaining required corporate action of the Company is
the approval and adoption of the Merger Agreement and the transactions
contemplated thereby by the affirmative vote of the holders of a majority of
the Shares. Accordingly, if the Minimum Condition is satisfied, the Purchaser
expects that it will have sufficient voting power to cause the approval and
adoption of the Merger Agreement and the transactions contemplated thereby
without the affirmative vote of any other stockholder of the Company.
 
  In the Merger Agreement, the Company has agreed to convene a meeting of its
stockholders as promptly as practicable following consummation of the Offer for
the purpose of considering and taking action on the Merger Agreement and the
transactions contemplated thereby. The Purchaser has agreed that all Shares
acquired by it pursuant to the Offer or the Stock Option Agreement will be
voted in favor of the Merger Agreement and the transactions contemplated
thereby.
 
  Appraisal Rights and Other Matters. No appraisal rights are available to
holders of Shares in connection with the Offer and no appraisal rights will be
available to holders of Shares in the Merger unless a portion of the
consideration to be paid in the Merger is cash. See Section 10. The Commission
has adopted Rule 13e-3 under the Exchange Act which is applicable to certain
"going private" transactions and which may under certain circumstances be
applicable to the Merger following the purchase of Shares pursuant to the Offer
or the Stock Option Agreement. Rule 13e-3 requires, among other things, that
certain financial information concerning the Company and certain information
relating to the fairness of the proposed transaction and the
 
                                       32

consideration offered to minority stockholders in such transaction be filed
with the Commission and disclosed to stockholders prior to consummation of the
transaction.
 
  Plans for the Company. The Purchaser presently intends to maintain and expand
the existing business of the Company and to promptly pursue new business
opportunities made available as a result of the Merger. Due to its highly
leveraged capital structure, the Company has been unable to take full advantage
of numerous growth opportunities in its fast-growing markets which would enable
it to maintain and enhance its natural competitive edge. The Purchaser expects
to be able to finance, on reasonable terms, the capital investment necessary to
exploit these opportunities, as well as additional opportunities to access the
abundant and long-lived natural gas supplies connected to some of the
Purchaser's existing natural gas pipeline assets. The Purchaser also
anticipates that the Company or the Purchaser or both, through their respective
subsidiaries, will promptly expand non-regulated activities in the geographical
areas served by the Company's pipeline subsidiaries. It is expected that the
capital structures of the Company and its natural gas pipeline subsidiaries
will be restructured as soon as reasonably practicable so as, among other
things, to eliminate or modify some or all of the more onerous restrictions in
their financing agreements. One result of this capital restructuring is
expected to be somewhat greater ratemaking flexibility for the natural gas
pipeline subsidiaries, as well as an overall lower cost of capital. The
Purchaser intends to aggressively continue the Company's program of disposing
of non-core assets.
 
  The Merger Agreement provides that the officers of the Company will continue
to be the officers of the Surviving Corporation. While the Purchaser has no
firm plans to immediately replace the management of the Company or its
subsidiaries, it is expected that a realignment of functions resulting, among
other things, from the Company's becoming a wholly-owned subsidiary of the
Purchaser will occur following the Merger in order to realize operating
efficiencies and savings in general and administrative costs.
 
  12. DIVIDENDS AND DISTRIBUTIONS. Except as contemplated by the Merger
Agreement (including, without limitation, the making of the Offer) and the
Stock Option Agreement, the Company has agreed that neither it nor any of its
subsidiaries will, between the date of the Merger Agreement and the Effective
Time, directly do any of the following without the prior written consent of the
Purchaser, which consent will not be unreasonably withheld: (a) except for
issuances of capital stock of the Company's subsidiaries to the Company or a
wholly-owned subsidiary of the Company, issue, reissue, sell or pledge or
authorize or propose the issuance, reissuance, sale or pledge of additional
shares of capital stock of any class, or securities convertible into capital
stock of any class, or any rights, warrants or options to acquire any
convertible securities or capital stock, other than the issuance of Shares (and
attached Company Rights) upon the exercise of stock options or vesting of
restricted or deferred stock unit awards outstanding on the date of the Merger
Agreement or upon conversion of Company Preferred Stock, in each case in
accordance with their present terms; (b) declare, set aside or pay any dividend
or other distribution (whether in cash, securities or property or any
combination thereof) in respect of any class or series of its capital stock,
except that (i) the Company may continue to pay regular dividends on the Shares
and shares of Company Preferred Stock consistent with past practice, (ii) TGPL
may continue to pay regular dividends and make annual sinking fund payments on
its cumulative first preferred stock consistent with past practice and (iii)
any wholly-owned subsidiary of the Company may pay dividends and make
distributions to the Company or any of the Company's wholly-owned subsidiaries;
or (c) adjust, split, combine, subdivide, reclassify or redeem, purchase or
otherwise acquire, or propose to redeem or purchase or otherwise acquire, any
shares of its capital stock, other than pursuant to certain specified
transactions or in connection with tax withholding features under certain of
the Company's employee incentive compensation.
 
  13. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; EXCHANGE LISTING AND
EXCHANGE ACT REGISTRATION. The purchase of Shares pursuant to the Offer will
reduce the number of Shares that might otherwise trade publicly and could
reduce the number of holders of Shares, which could adversely affect the
liquidity and market value of the remaining Shares held by the public.
 
                                       33

  According to the NYSE's published guidelines, the NYSE would consider
delisting the Shares if, among other things, the number of record holders of at
least 100 Shares should fall below 1,200, the number of publicly held Shares
(exclusive of holdings of officers, directors and their families and other
concentrated holdings of 10% or more ("NYSE Excluded Holdings")) should fall
below 600,000 or the aggregate market value of publicly held Shares (exclusive
of NYSE Excluded Holdings) should fall below $5,000,000. If, as a result of the
purchase of Shares pursuant to the Offer, the Stock Option Agreement or
otherwise, the Shares no longer meet the requirements of the NYSE for continued
listing and the listing of the Shares is discontinued, the market for the
Shares could be adversely affected.
 
  If the NYSE were to delist the Shares, it is possible that the Shares would
continue to trade on another securities exchange or in the over-the-counter
market and that price or other quotations would be reported by such exchange or
through the National Association of Securities Dealers Automated Quotation
System ("NASDAQ") or other sources. The extent of the public market therefor
and the availability of such quotations would depend, however, upon such
factors as the number of stockholders and/or the aggregate market value of such
securities remaining at such time, the interest in maintaining a market in the
Shares on the part of securities firms, the possible termination of
registration under the Exchange Act as described below, and other factors. The
Purchaser cannot predict whether the reduction in the number of Shares that
might otherwise trade publicly would have an adverse or beneficial effect on
the market price for or marketability of the Shares or whether it would cause
future market prices to be greater or less than the price paid to a holder of
the Shares pursuant to the Offer.
 
  The Shares are currently "margin securities", as such term is defined under
the rules of the Board of Governors of the Federal Reserve System (the "Federal
Reserve Board"), which has the effect, among other things, of allowing brokers
to extend credit on the collateral of such securities. Depending upon factors
similar to those described above regarding listing and market quotations,
following the Offer it is possible that the Shares might no longer constitute
"margin securities" for purposes of the margin regulations of the Federal
Reserve Board, in which event such Shares could no longer be used as collateral
for loans made by brokers.
 
  The Shares are currently registered under the Exchange Act. Such registration
may be terminated upon application of the Company to the Commission if the
Shares are not listed on a national securities exchange and there are fewer
than 300 record holders of the Shares. The termination of registration of the
Shares under the Exchange Act would substantially reduce the information
required to be furnished by the Company to holders of Shares and to the
Commission and would make certain provisions of the Exchange Act, such as the
short-swing profit recovery provisions of Section 16(b), the requirement of
furnishing a proxy statement in connection with stockholders' meetings pursuant
to Section 14(a), and the requirements of Rule 13e-3 under the Exchange Act
with respect to "going private" transactions, no longer applicable to the
Shares. In addition, "affiliates" of the Company and persons holding
"restricted securities" of the Company may be deprived of the ability to
dispose of such securities pursuant to Rule 144 promulgated under the
Securities Act of 1933.
 
  If registration of the Shares under the Exchange Act were terminated, the
Shares would no longer be "margin securities" or be eligible for NASDAQ
reporting.
 
  14. CERTAIN CONDITIONS OF THE OFFER. Notwithstanding any other provision of
the Offer, the Purchaser will not be required to accept for payment or, subject
to applicable rules and regulations of the Commission, including Rule 14e-1(c)
under the Exchange Act, to pay for any Shares tendered pursuant to the Offer,
and may, subject to the provisions of Section 1.1 of the Merger Agreement,
terminate the Offer or postpone the acceptance for payment of, Shares tendered,
if as of the expiration of the Offer (as the Offer may have been
 
                                       34

extended pursuant to Section 1.1 of the Merger Agreement) (i) the Minimum
Condition shall not have been satisfied, (ii) the waiting period under the HSR
Act applicable to the Offer and the Merger have not expired or been terminated
or (iii) at any time on or after December 12, 1994 and prior to the time of

below have occurred and be continuing:
 
    (a) there has been any action taken, or any statute, rule, regulation,
  judgment, order or injunction promulgated, enacted, entered or deemed
  applicable to the Offer or the Merger, by any state or United States
  federal governmental authority or by any domestic court that (i) makes the
  acceptance for payment of or payment for Shares illegal or otherwise
  prohibiting consummation of the Offer or the Merger, (ii) renders the
  Purchaser unable to accept for payment, pay for or purchase the Shares,
  (iii) imposes material limitations on the ability of the Purchaser to
  acquire or hold, transfer or dispose of, or effectively to exercise any of
  its material rights of ownership of, the Shares, including, without
  limitation, the right to vote the Shares purchased by it on all matters
  properly presented to the stockholders of the Company, (iv) as a result of
  the Offer or the Merger, requires the Purchaser, the Company, or any of
  their respective subsidiaries or affiliates to dispose of or hold separate
  all or any material portion of their respective businesses, assets or
  properties or imposing any material limitations on the ability of any such
  entities to conduct their respective businesses and own such assets and
  properties, or (v) as a result of the Offer or the Merger, imposes any
  limitations on the ability of the Purchaser or any of its subsidiaries
  effectively to control in any material respect the business or operations
  of the Company or any of its subsidiaries;
 
    (b) there has been instituted or are pending any action, proceeding or
  counterclaim by or before any U.S. federal or state court or governmental,
  administrative or regulatory agency or authority, or any other person, in
  each case that has a substantial likelihood of success, seeking to restrain
  or prohibit the making of the Offer or the Merger, seeking to obtain any
  damages material to the Purchaser and its subsidiaries taken as a whole as
  a result thereof or seeking to prohibit the ownership by the Purchaser or
  any of its subsidiaries of the Shares or of any material portion of their
  businesses or assets, or to compel the Purchaser, the Company or any of
  their affiliates to dispose of or hold separate all or a material portion
  of any of their business or assets, in each case as a result of the Offer
  or the Merger;
 
    (c) there has occurred (i) any general suspension of, or limitation on
  prices for, trading in securities on the NYSE, (ii) a decline of at least
  25% in either the Dow Jones Average of Industrial Stocks or the Standard &
  Poor's 500 Index from December 12, 1994, (iii) the declaration of a banking
  moratorium or any suspension of payments in respect of banks in the United
  States, (iv) any limitation by any governmental authority on, or any other
  event which could reasonably be expected to have a material adverse effect
  on, the extension of credit by banks or other lending institutions, which
  limitation or other event is reasonably likely to materially affect the
  ability of the Purchaser to pay for the Shares, or (v) in the case of any
  of the foregoing existing at the time of the commencement of the Offer, a
  material acceleration or worsening thereof;
 
    (d) any material adverse change has occurred since December 12, 1994 in
  the business, assets, results of operation or financial condition of the
  Company and its subsidiaries taken as a whole, other than changes arising
  from general economic or industry conditions, or a failure by the banks
  which are parties to the Company's revolving credit and letter of credit
  reimbursement agreements to have provided the Bank Consents;
 
    (e) the Company has breached or failed to perform in any material respect
  any of its material obligations under the Merger Agreement, including
  without limitation a failure to cause the Company Rights to be redeemed as
  provided for therein;
 
    (f) the representations and warranties of the Company contained in the
  Merger Agreement were not true and correct in all material respects when
  made or have since ceased to be true and correct in all material respects
  and remain incorrect at the expiration date of the Offer;
 
    (g) the Merger Agreement has been terminated in accordance with its
  terms; and
 
    (h) the Purchaser and the Company have agreed that the Purchaser will
  amend or terminate the Offer;
 
                                       35

which, in the reasonable judgment of the Purchaser with respect to each and
every matter referred to above and regardless of the circumstances (including
any action or inaction by the Purchaser) giving rise to any such condition,
makes it inadvisable to proceed with the Offer or with such acceptance for
payment or such payment.
 
  The foregoing conditions are for the benefit of the Purchaser and, except or
as otherwise provided in the Merger Agreement, may be waived by the Purchaser
in whole or in part at any time and from time to time in its reasonable
discretion. The failure by the Purchaser at any time to exercise any of the
foregoing rights will not be deemed a waiver of any right and each right will
be deemed an ongoing right which may be asserted by the Purchaser at any time
and from time to time.
 
  15. CERTAIN LEGAL MATTERS; REGULATORY APPROVALS.
 
  General. Based upon its examination of publicly available information with
respect to the Company and the review of certain information furnished by the
Company to the Purchaser and discussions of representatives of the Purchaser
with representatives of the Company during the Purchaser's investigation of the
Company, the Purchaser is not aware of any license or other regulatory permit
that appears to be material to the business of the Company and its
subsidiaries, taken as a whole, which might be adversely affected by the
acquisition of Shares by the Purchaser pursuant to the Offer or the Stock
Option Agreement or the Merger or, except as set forth below, of any approval
or other action by any domestic (federal or state) or foreign governmental,
administrative or regulatory authority or agency which would be required prior
to the acquisition of Shares by the Purchaser pursuant to the Offer or the
Stock Option Agreement or prior to the Merger. Should any such approval or
other action be required, it is the Purchaser's present intention to seek such
approval or action. The Purchaser does not currently intend, however, to delay
the purchase of Shares tendered pursuant to the Offer pending the outcome of
any such action or the receipt of any such approval. There can be no assurance
that any such approval or other action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to the
business of the Company or the Purchaser or that certain parts of the
businesses of the Company or the Purchaser might not have to be disposed of or
held separate or other substantial conditions complied with in order to obtain
such approval or other action or in the event that such approval was not
obtained or such other action was not taken. The Purchaser's obligation under
the Offer to accept for payment and pay for Shares is subject to certain
conditions, including conditions relating to the legal matters discussed in
this Section 15. See Section 14.
 
  Antitrust Compliance. Under the HSR Act and the rules that have been
promulgated thereunder by the FTC, certain acquisition transactions may not be
consummated unless certain information has been furnished to the Antitrust
Division and the FTC and certain waiting period requirements have been
satisfied. Pursuant to such requirements, the Purchaser and the Company are
making the initial filings under the HSR Act and the waiting period thereunder
will expire at 11:59 p.m., New York City time, on the fifteenth day following
such filings, unless earlier terminated. Prior to such time, the Antitrust
Division or the FTC may extend the waiting period by requesting additional
information or documentary material relevant to the acquisitions. If such a
request is made, the waiting period will be extended until 11:59 p.m., New York
City time, on the tenth day after substantial compliance by the Purchaser with
such request.
 
  The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the proposed acquisition of Shares
by the Purchaser pursuant to the Offer. At any time before or after the
purchase of Shares pursuant to the Offer by the Purchaser, the FTC or the
Antitrust Division could take such action under the antitrust laws as it deems
necessary or desirable in the public interest, including seeking to enjoin the
purchase of Shares pursuant to the Offer or seeking the divestiture of Shares
purchased by the Purchaser or the divestiture of substantial assets of the
Purchaser and the Company or their respective subsidiaries. Private parties and
state attorneys general may also bring legal action under federal or state
antitrust laws under certain circumstances. Based upon an examination of
information available to the Purchaser relating to the businesses in which the
Purchaser and the Company and their respective subsidiaries are engaged, the
Purchaser believes that the Offer will not violate the antitrust laws.
Nevertheless, there can be no assurance that a challenge to the Offer on
antitrust grounds will not be made or, if such a challenge is made, what the
result would be. See Section 14.
 
                                       36

  State Takeover Statutes. The Company is incorporated under the laws of the
State of Delaware. In general, Section 203 of the Delaware Law prevents an
"interested stockholder" (generally a person who owns or has the right to
acquire 15% or more of a corporation's outstanding voting stock, or an
affiliate or associate thereof) from engaging in a "business combination"
(defined to include mergers and certain other transactions) with a Delaware
corporation for a period of three years following the date such person became
an interested stockholder unless, among other things, prior to such date the
board of directors of the corporation approved either the business combination
or the transaction in which the interested stockholder became an interested
stockholder. On December 11, 1994, prior to the execution of the Merger
Agreement and the Stock Option Agreement, the Company Board by the unanimous
vote of all directors present at a meeting held on such date, approved the
Merger Agreement and the Stock Option Agreement and determined that the Offer
and the Merger, taken together, are fair to, and in the best interests of, the
stockholders of the Company. Accordingly, Section 203 is inapplicable to the
Offer and the Merger.
 
  A number of other states have adopted laws and regulations applicable to
attempts to acquire securities of corporations which are incorporated, or have
substantial assets, stockholders, principal executive offices or principal
places of business, or whose business operations otherwise have substantial
economic effects, in such states. In 1982, in Edgar v. MITE Corp., the Supreme
Court of the United States invalidated on constitutional grounds the Illinois
Business Takeover Statute, which, as a matter of state securities law, made
takeovers of corporations meeting certain requirements more difficult. However,
in 1987 in CTS Corp. v. Dynamics Corp. of America, the Supreme Court held that
the State of Indiana may, as a matter of corporate law, and, in particular,
with respect to those aspects of corporate law concerning corporate governance,
constitutionally disqualify a potential acquiror from voting on the affairs of
a target corporation without the prior approval of the remaining stockholders.
The state law before the Supreme Court was by its terms applicable only to
corporations that had a substantial number of stockholders in the state and
were incorporated there.
 
  The Company, directly or through subsidiaries, conducts business in a number
of states throughout the United States, some of which have enacted takeover
laws. The Purchaser does not know whether any of these laws will, by their
terms, apply to the Offer and has not complied with any such laws. Should any
person seek to apply any state takeover law, the Purchaser will take such
action as then appears desirable, which may include challenging the validity or
applicability of any such statute in appropriate court proceedings. In the
event it is asserted that one or more state takeover laws is applicable to the
Offer and the Merger, and an appropriate court does not determine that it is
inapplicable or invalid as applied to the Offer, the Purchaser might be
required to file certain information with, or receive approvals from, the
relevant state authorities. In addition, if enjoined, the Purchaser might be
unable to accept for payment any Shares tendered pursuant to the Offer, or be
delayed in continuing or consummating the Offer. In such case, the Purchaser
may not be obligated to accept for payment any Shares tendered. See Section 14.
 
  Federal Reserve Board Regulations. Federal Reserve Board Regulations G, T, U
and X (the "Margin Regulations") promulgated by the Federal Reserve Board place
restrictions on the amount of credit that may be extended for the purpose of
purchasing margin stock (including the Shares) if such credit is secured
directly or indirectly by margin stock. The Purchaser believes that the
financing of the acquisition of the Shares will be in compliance with the
Margin Regulations. A challenge to the financing arrangements in respect of the
Offer alleging a violation of the Margin Regulations could, if adversely
determined, impair the Purchaser's ability to obtain financing for the Offer
and the Merger.
 
  New Jersey Industrial Site Recovery Act. The New Jersey Industrial Site
Recovery Act ("ISRA"), P.L. 1993 c.139, requires that a "Negative Declaration"
or a "Remedial Action Workplan" be filed with and approved by the New Jersey
Department of Environmental Protection ("NJDEP") as a precondition to the
"transfer" of an "industrial establishment." Prerequisites for the approval of
a Negative Declaration or Remedial Action Workplan include the filing of
detailed information about environmental conditions at the "industrial
establishment." In certain cases, the NJDEP may require (i) soil and ground
water sampling, (ii) submission and implementation of a Remedial Action
Workplan for any contamination above a certain
 
                                       37

threshold level at the "industrial establishments," and (iii) a financial
guarantee, such as a remediation trust fund, environmental insurance policy,
line of credit, or self-guarantee, of the implementation of the Remedial Action
Workplan. The NJDEP, in circumstances deemed appropriate, has in the past
entered into "Remediation Agreements" with the owner or operator of an
"industrial establishment" subject to ISRA pursuant to which consummation of a
"transfer" of such "industrial establishment" was allowed prior to full
compliance with the requirements of ISRA, provided that the owner or operator
(i) agrees to a schedule for compliance and (ii) gives the NJDEP a financial
guarantee of such compliance.
 
  The Purchaser has been advised that the consummation of the Offer may
constitute a "transfer" as defined by ISRA. If the consummation of the Offer is
a covered "transfer" and if any of the Company's facilities in the State of New
Jersey are "industrial establishments" as defined by ISRA, the requirements of
ISRA would be applicable. If the Company determines that the consummation of
the Offer will trigger ISRA with respect to one or more of its facilities, the
Company intends to make timely filings in accordance with the requirements of
the law.
 
  Certain Litigation. On December 12, 1994, two purported class actions were
filed in the Delaware Court of Chancery captioned, Steiner v. DesBarres, et
al., Del. Ch., C.A. No. 13920 in which the Company, the Purchaser and eight
directors of the Company were named as defendants, and Alpern v. Transco Energy
Co., et al., Del. Ch., C.A. No. 13918 in which the Purchaser and seven
directors of the Company were named as defendants. On December 13, 1994, two
additional purported class actions were filed, captioned, Miller v. DesBarres
et al., Del. Ch., C.A. No. 13922 and Weiss v. DesBarres, et al., Del. Ch., C.A.
No. 13923, in which the Company and seven directors of the Company were named
as defendants. On December 14, 1994, two additional purported class actions
were filed in the Delaware Court of Chancery captioned, DeCesare v. DesBarres,
et al., Del. Ch. C.A. No. 13926 in which the Company, the Purchaser and eight
directors were named as defendants and Rand, et al. v. DesBarres et al., Del.
Ch. C.A. No. 13925, in which the Company and seven directors were named as
defendants. Among other things, all of the complaints allege: that the
directors of the Company breached their fiduciary duties in connection the
Merger Agreement, including the Option granted under the Stock Option
Agreement. The complaints further allege that the Purchaser has aided and
abetted the Company directors' alleged breaches of fiduciary duty. The
complaints seek, among other relief, an injunction against the Offer and the
Merger.
 
  The Purchaser believes that the lawsuits are without merit, and intends to
vigorously defend the actions.
 
  16. FEES AND EXPENSES. Except as set forth below, the Purchaser will not pay
any fees or commissions to any broker, dealer or other person for soliciting
tenders of Shares pursuant to the Offer.
 
  Smith Barney Inc. ("Smith Barney") is acting as the Dealer Manager in
connection with the Offer and as financial advisor to the Purchaser in
connection with its effort to acquire the Company. The Purchaser has agreed to
pay Smith Barney for its services the following fees: (i) a merger agreement
execution fee of $1,125,000, payable upon execution of the Merger Agreement;
(ii) a dealer manager fee of $1,125,000, payable at such time as the Purchaser
accepts for payment and purchases in excess of 50% of the outstanding Shares;
and (iii) a transaction fee of $4,500,000 (against which the prior fees, to the
extent previously paid, will be credited), payable promptly upon consummation
of certain specified transactions concerning the Company, including the
purchase of at least 50% of the outstanding Shares pursuant to the Offer. The
Purchaser has also agreed to reimburse Smith Barney for its reasonable out-of-
pocket expenses (including the reasonable fees and expenses of its legal
counsel) incurred in connection with its engagement, and to indemnify Smith
Barney and certain related persons against certain liabilities and expenses in
connection with its engagement, including certain liabilities under the federal
securities laws. Smith Barney has rendered various investment banking and other
advisory services to the Purchaser and its affiliates in the past and is
expected to continue to render such services, for which it has received and
will continue to receive customary compensation from the Purchaser and its
affiliates. In the ordinary course of business, Smith Barney may actively trade
the equity and debt securities of the Purchaser and the Company for its own
account or for the account of customers and, accordingly, may at any time hold
a long or short position in such securities.
 
                                       38

  The Purchaser has retained Morrow & Co. to act as the Information Agent in
connection with the Offer. The Information Agent may contact holders of Shares
by mail, telephone, facsimile, telegraph and personal interviews and may
request brokers, dealers and other nominee stockholders to forward materials
relating to the Offer to beneficial owners of Shares. The Information Agent
will receive reasonable and customary compensation for its services, will be
reimbursed for certain reasonable out-of-pocket expenses and will be
indemnified against certain liabilities and expenses in connection therewith,
including certain liabilities under the federal securities laws.
 
  In addition, Chemical Bank has been retained as the Depositary. The
Depositary has not been retained to make solicitations or recommendations in
its role as Depositary. The Depositary will receive reasonable and customary
compensation for its services, will be reimbursed for certain reasonable out-
of-pocket expenses and will be indemnified against certain liabilities and
expenses in connection therewith, including certain liabilities under the
federal securities laws. Brokers, dealers, commercial banks and trust companies
will be reimbursed by the Purchaser for customary mailing and handling expenses
incurred by them in forwarding offering material to their customers.
 
  17. MISCELLANEOUS. The Purchaser is not aware of any jurisdiction where the
making of the Offer is prohibited by any administrative or judicial action
pursuant to any valid state statute. If the Purchaser becomes aware of any
valid state statute prohibiting the making of the Offer or the acceptance of
the Shares pursuant thereto, Purchaser will make a good faith effort to comply
with such state statute. If, after such good faith effort, the Purchaser cannot
comply with any such state statute, the Offer will not be made to (nor will
tenders be accepted from or on behalf of) the holders of Shares in such state.
In any jurisdiction where the securities, blue sky or other laws require the
Offer to be made by a licensed broker or dealer, the Offer shall be deemed to
be made on behalf of the Purchaser by the Dealer Manager or one or more
registered brokers or dealers which are licensed under the laws of such
jurisdiction.
 
  NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF THE PURCHASER NOT CONTAINED IN THIS OFFER TO
PURCHASE OR IN THE LETTER OF TRANSMITTAL AND, IF GIVEN OR MADE, SUCH
INFORMATION OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN
AUTHORIZED.
 
  The Purchaser has filed with the Commission the Schedule 14D-1, together with
exhibits, pursuant to Rule 14d-3 of the General Rules and Regulations under the
Exchange Act, furnishing certain additional information with respect to the
Offer, and may file amendments thereto. The Schedule 14D-1 and any amendments
thereto, including exhibits, may be inspected at, and copies may be obtained
from, the same places and in the same manner as set forth in Section 7 (except
that they will not be available at the regional offices of the Commission).

Ladies and Gentlemen:
 
  The undersigned hereby tenders to The Williams Companies, Inc. (the
"Purchaser"), a Delaware corporation, the above described shares of common
stock, par value $.50 per share (the "Shares"), of Transco Energy Company, a
Delaware corporation (the "Company"), and attached common share purchase rights
(the "Company Rights" and, unless the context otherwise requires, deemed to be
included in all references to "Shares") pursuant to the Purchaser's offer to
purchase up to 24,600,000 Shares at a price of $17.50 per Share, net to the
seller in cash without interest upon the terms and subject to the conditions
set forth in the Offer to Purchase, dated December 16, 1994 (the "Offer to
Purchase"), receipt of which is hereby acknowledged, and in this Letter of
Transmittal (which, together with any amendments or supplements thereto,
constitute the "Offer"). The Offer is being made pursuant to an Agreement and
Plan of Merger (the "Merger Agreement"), dated as of December 12, 1994, between
the Purchaser, WC Acquisition Corp., a Delaware corporation and a wholly-owned
subsidiary of the Purchaser and the Company. The Purchaser reserves the right
to transfer or assign in whole or from time to time in part, to one or more of
its affiliates the right to purchase Shares tendered pursuant to the Offer.
 
  Subject to, and effective upon, acceptance for payment of the Shares tendered
herewith in accordance with the terms and subject to the conditions of the
Offer, the undersigned hereby sells, assigns, and transfers to, or upon the
order of, the Purchaser all right, title and interest in and to all the Shares
that are being tendered hereby (and any and all other Shares or other
securities issued or issuable in respect thereof on or after December 12, 1994)
and irrevocably constitutes and appoints the Depositary the true and lawful
agent and attorney-in-fact of the undersigned with respect to such Shares (and
any such other Shares or securities) with full power of substitution (such
power of attorney being deemed to be an irrevocable power coupled with an
interest), to (a) deliver certificates for such Shares (and any such other
Shares or securities), or transfer ownership of such Shares (and any such other
Shares or securities) on the account books maintained by a Book-Entry Transfer
Facility, together in either such case with all accompanying evidences of
transfer and authenticity, to or upon the order of the Purchaser upon receipt
by the Depositary, as the undersigned's agent, of the purchase price (adjusted,
if appropriate, as provided in the Offer to Purchase), (b) present such Shares
(and any such other Shares or securities) for transfer on the books of the
Company and (c) receive all benefits and otherwise exercise all rights of
beneficial ownership of such Shares (and any other such Shares or securities),
all in accordance with the terms of the Offer.
 
  If, on or after December 12, 1994, the Company should declare or pay, other
than as specifically permitted under the Merger Agreement, any cash or stock
dividend or other distribution on or issue any rights with respect to the
Shares, payable or distributable to stockholders of record on a date before the
transfer to the name of the Purchaser or its nominee or transferee on the
Company's stock transfer records of the Shares accepted for payment pursuant to
the Offer, then, subject to the provisions of Section 14 of the Offer to
Purchase, (i) the purchase price per Share payable by the Purchaser pursuant to
the Offer will be reduced by the amount of any such cash dividend or cash
distribution and (ii) the whole of any such non-cash dividend, distribution or
right will be received and held by the tendering stockholder for the account of
the Purchaser and shall be required to be promptly remitted and transferred by
each tendering stockholder to the Depositary for the account of the Purchaser,
accompanied by appropriate documentation of transfer. Pending such remittance,
the Purchaser will be entitled to all rights and privileges as owner of any
such non-cash dividend, distribution or right and may withhold the entire
purchase price or deduct from the purchase price the amount of value thereof,
as determined by the Purchaser in its sole discretion.
 
  By executing this Letter of Transmittal, the undersigned hereby confirms the
undersigned's agreement that the amount paid by the Company in redemption of
the Company Rights attached to Shares of such stockholder acquired pursuant to

                                       3

  The undersigned hereby irrevocably appoints J. Furman Lewis and David Higbee
and each of them or any other designees of the Purchaser, the attorneys-in-fact
and proxies of the undersigned, each with full power of substitution to the
full extent of such stockholder's rights with respect to tendered Shares (and
any and all other Shares or securities or rights issued or issuable in respect
thereof on or after December 12, 1994), to vote in such manner as each such
attorney and proxy or his substitute shall in his sole discretion deem proper,
and otherwise act (including without limitation pursuant to written consent)
with respect to all the Shares tendered hereby which have been accepted for
payment by the Purchaser prior to the time of such vote or action, which the
undersigned is entitled to vote at any meeting of stockholders (whether annual
or special and whether or not an adjourned meeting) of the Company, or
otherwise. This proxy is coupled with an interest in the Company and in the
Shares and is irrevocable and is granted in consideration of, and is effective
when, if and to the extent that the Purchaser accepts such Shares for payment
pursuant to the Offer. Such acceptance for payment shall revoke, without
further action, all prior proxies granted by the undersigned at any time with
respect to such Shares (and any such other Shares or other securities) and no
subsequent proxies will be given (and if given will be deemed not to be
effective) with respect thereto by the undersigned. The undersigned
acknowledges that in order for Shares to be deemed validly tendered,
immediately upon the acceptance for payment of such Shares, the Purchaser or
the Purchaser's designee must be able to exercise full voting and other rights
of a record and beneficial holder with respect to such Shares.
 
  The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Shares tendered
hereby (and any and all other Shares or other securities issued or issuable in
respect thereof on or after December 12, 1994), that the undersigned own(s) the
Shares tendered hereby within the meaning of Rule 14e-4 promulgated under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), that such
tender of shares complies with Rule 14e-4 under the Exchange Act, and that,
when the same are accepted for payment by the Purchaser, the Purchaser will
acquire good, marketable and unencumbered title thereto, free and clear of all
liens, restrictions, charges and encumbrances and the same will not be subject
to any adverse claim. The undersigned, upon request, will execute and deliver
any additional documents deemed by the Depositary or the Purchaser to be
necessary or desirable to complete or confirm the sale, assignment and transfer
of the Shares tendered hereby (and any and all such other Shares or other
securities).
 
  All authority herein conferred or agreed to be conferred in this Letter of
Transmittal shall not be affected by, and shall survive, the death or
incapacity of the undersigned, and any obligation of the undersigned hereunder
shall be binding upon the successors, assigns, heirs, executors,
administrators, trustees in bankruptcy and personal and legal representatives
of the undersigned. Except as stated in the Offer to Purchase, this tender is
irrevocable provided that Shares tendered pursuant to the Offer may be
withdrawn at any time prior to the Expiration Date.
 
  The undersigned understands that tenders of Shares pursuant to any one of the
procedures described in Section 3 of the Offer to Purchase and in the
instructions hereto will constitute a binding agreement between the undersigned
and the Purchaser upon the terms and subject to the conditions of the Offer.
The undersigned recognizes that under certain circumstances set forth in the
Offer to Purchase, Purchaser may not be required to accept for payment any of
the Shares tendered hereby.
 
  Unless otherwise indicated herein under "Special Payment Instructions,"
please issue the check for the purchase price and/or any certificates for
Shares not tendered or accepted for payment in the name(s) of the undersigned.
Similarly, unless otherwise indicated under "Special Delivery Instructions,"
please mail the check for the purchase price and/or return any certificates for
Shares not tendered or accepted for payment (and accompanying documents, as
appropriate) to the undersigned at the address shown below the undersigned's
signature. In the event that both the Special Delivery Instructions and the
Special Payment Instructions are completed, please issue the check for the
purchase price and/or any certificates for Shares not tendered or accepted for
payment in the name of, and deliver such check and/or return such certificates
to the person or persons so indicated. Stockholders delivering Shares by book-
entry transfer may request that
 
                                       4

any Shares not accepted for payment be returned by crediting such account
maintained at a Book-Entry Transfer Facility as such stockholder may designate
by making an appropriate entry under "Special Payment Instructions." The
undersigned recognizes that the Purchaser has no obligation pursuant to the
Special Payment Instructions to transfer any Shares from the name of the
registered holder thereof if the Purchaser does not accept for payment any of
the Shares so tendered.

                                  INSTRUCTIONS
 
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
  1. Guarantee of Signatures. No signature guarantee on this Letter of
Transmittal is required (i) if this Letter of Transmittal is signed by the
registered holder of the Shares (which term, for purposes of this document,
shall include any participant in a Book-Entry Transfer Facility whose name
appears on a security position listing as the owner of Shares) tendered
herewith, unless such holder has completed either the box entitled "Special
Delivery Instructions" or the box entitled "Special Payment Instructions" on
the reverse hereof, or (ii) if such Shares are tendered for the account of a
member firm of a registered national securities exchange, a member of the
National Association of Securities Dealers, Inc. or a commercial bank or trust
company having an office or correspondent in the United States (each of the
foregoing being referred to as an "Eligible Institution"). In all other cases,
all signatures on this Letter of Transmittal must be guaranteed by an Eligible
Institution. See Instruction 5.
 
  2. Delivery of Letter of Transmittal and Certificates. This Letter of
Transmittal is to be completed by stockholders either if certificates are to be
forwarded herewith or if tenders of Shares are to be made pursuant to the
procedures for delivery by book-entry transfer set forth in Section 3 of the
Offer to Purchase. Certificates for all physically tendered Shares, or any
Book-Entry Confirmation of Shares, as the case may be, as well as a properly
completed and duly executed Letter of Transmittal (or manually signed facsimile
thereof), with any required signature guarantees, and any other documents
required by this Letter of Transmittal, or an Agent's Message (as defined
below), in connection with a book-entry transfer, must be transmitted to and
received by the Depositary at one of its addresses set forth herein prior to
the Expiration Date (as defined in Section 1 of the Offer to Purchase). If a
stockholder's certificates for Shares are not immediately available or time
will not permit all required documents to reach the Depositary prior to the
Expiration Date or the procedure for book-entry transfer cannot be completed on
a timely basis, such stockholder's Shares may nevertheless be tendered by
properly completing and duly executing the Notice of Guaranteed Delivery
pursuant to the guaranteed delivery procedure set forth in Section 3 of the
Offer to Purchase. Pursuant to such procedure, (i) such tender must be made by
or through an Eligible Institution, (ii) a properly completed and duly executed
Notice of Guaranteed Delivery, substantially in the form provided by the
Purchaser, must be received by the Depositary prior to the Expiration Date, and
(iii) in the case of a guarantee of Shares, the certificates for all tendered
Shares, in proper form for transfer, or a Book-Entry Confirmation, together
with a properly completed and duly executed Letter of Transmittal (or manually
signed facsimile thereof) with any required signature guarantee (or, in the
case of a book-entry transfer, an Agent's Message) and any other documents
required by such Letter of Transmittal, are received by the Depositary within
five New York Stock Exchange, Inc. trading days after the date of execution of
the Notice of Guaranteed Delivery. The term "Agent's Message" means a message,
transmitted by a Book-Entry Transfer Facility to, and received by, the
Depositary and forming a part of a Book-Entry Confirmation, which states that
such Book-Entry Transfer Facility has received an express acknowledgement from
the participant in such Book-Entry Transfer Facility tendering the Shares, that
such participant has received and agrees to be bound by the terms of the Letter
of Transmittal and that the Purchaser may enforce such agreement against the
participant.
 
  THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, THE CERTIFICATE FOR
SHARES AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-
ENTRY TRANSFER FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING
STOCKHOLDER, AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED
BY THE DEPOSITARY. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY. EXCEPT AS OTHERWISE PROVIDED IN
THIS INSTRUCTION 2, THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY
RECEIVED BY THE DEPOSITARY.
 
  No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. All tendering stockholders, by execution
of this Letter of Transmittal (or a manually signed facsimile thereof), waive
any right to receive any notice of the acceptance of their Shares for payment.
 
                                       7

  3. Inadequate Space. If the space provided herein is inadequate, the
certificate numbers and/or the number of Shares should be listed on a separate
signed schedule attached hereto.
 
  4. Partial Tenders. (Not applicable to stockholders who tender by book-entry
transfer.) If fewer than all the Shares evidenced by any certificate submitted
are to be tendered, fill in the number of Shares which are to be tendered in
the box entitled "Description of Shares Tendered." In such case, new
certificate(s) for the remainder of the Shares that were evidenced by your old
certificate(s) will be sent to you, unless otherwise provided in the
appropriate box on this Letter of Transmittal, as soon as practicable after the
Expiration Date. All Shares represented by certificates delivered to the
Depositary will be deemed to have been tendered unless otherwise indicated.
 
  5. Signatures on Letter of Transmittal, Stock Powers and Endorsements. If
this Letter of Transmittal is signed by the registered holder(s) of the Shares
tendered hereby, the signature(s) must correspond exactly with the name(s) as
written on the face of the certificate(s) without alteration, enlargement or
any change whatsoever.
 
  If any of the Shares tendered hereby are owned of record by two or more joint
owners, all such owners must sign this Letter of Transmittal.
 
  If any tendered Shares are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations of
certificates.
 
  If this Letter of Transmittal or any certificates or stock powers are signed
by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and proper evidence satisfactory
to the Purchaser of such person's authority so to act must be submitted.
 
  When this Letter of Transmittal is signed by the registered owner(s) of the
Shares listed and transmitted hereby, no endorsement of certificates or
separate stock powers are required unless payment or certificates for Shares
not tendered or purchased are to be issued to a person other than the
registered owner(s). Signatures on such certificates or stock powers must be
guaranteed by an Eligible Institution.
 
  If this Letter of Transmittal is signed by a person other than the registered
owner(s) of the Shares listed, the certificates must be endorsed or accompanied
by appropriate stock powers, in either case signed exactly as the name(s) of
the registered holder(s) appear on the certificates. Signatures on such
certificates or stock powers must be guaranteed by an Eligible Institution.
 
  6. Stock Transfer Taxes. Except as set forth in this Instruction 6, the
Purchaser will pay or cause to be paid any stock transfer taxes with respect to
the transfer and sale of purchased Shares to it or its order pursuant to the
Offer. If payment of the purchase price is to be made, or if certificates for
Shares not tendered or purchased are to be registered in the name of, any
person other than the registered holder, or if tendered certificates are
registered in the name of any person other than the person(s) signing this
Letter of Transmittal, the amount of any stock transfer taxes (whether imposed
on the registered holder or such person) payable on account of the transfer to
such person will be deducted from the purchase price unless satisfactory
evidence of the payment of such taxes or exemption therefrom is submitted.
 
  EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF
TRANSMITTAL.
 
  7. Special Payment and Delivery Instructions. If a check and/or certificates
for unpurchased Shares are to be issued in the name of a person other than the
signer of this Letter of Transmittal or if a check is to be sent and/or such
certificates are to be returned to someone other than the signer of this Letter
of Transmittal or to an address other than that shown above, the appropriate
boxes on this Letter of Transmittal should be completed. Stockholders tendering
Shares by book-entry transfer may request that Shares not
 
                                       8

purchased be credited to such account maintained at a Book-Entry Transfer
Facility as such stockholder may designate hereon. If no such instructions are
given, such Shares not purchased will be returned by crediting the account at
the Book-Entry Transfer Facility designated above.
 
  8. Requests for Assistance or Additional Copies. Requests for assistance may
be directed to the Dealer Manager or the Information Agent at the addresses set
forth below. Additional copies of the Offer to Purchase, this Letter of
Transmittal, the Notice of Guaranteed Delivery and the Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 may be
obtained from the Dealer Manager or the Information Agent at the address set
forth below or from your broker, dealer, commercial bank or trust company.
 
  9. Waiver of Conditions. The conditions of the Offer may be waived, in whole
or in part, by the Purchaser, in its sole discretion, at any time and from time
to time, in the case of any Shares tendered.
 
  10. 31% Backup Withholding; Substitute Form W-9. Under federal income tax
laws, a stockholder whose tendered Shares are accepted for payment is required
to provide the Depositary with such stockholder's correct taxpayer
identification number ("TIN") on Substitute Form W-9 below and certify under
penalties of perjury that such number is correct and that such stockholder is
not subject to backup withholding. If the Depositary is not provided with the
correct TIN and certifications are not provided, the Internal Revenue Service
may subject the stockholder or other payee to a $50 penalty. In addition,
payments that are made to such stockholder or other payee with respect to
Shares purchased pursuant to the Offer may be subject to 31% backup
withholding.
 
  Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, the stockholder must submit a Form W-8, signed under penalties of
perjury, attesting to that individual's exempt status. A Form W-8 can be
obtained from the Depositary. See the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for more instructions.
 
  If backup withholding applies, the Depositary is required to withhold 31% of
any such payments made to the stockholder or other payee. Backup withholding is
not an additional tax. Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained from the Internal
Revenue Service.
 
  To prevent backup withholding on payments that are made to a stockholder with
respect to Shares purchased pursuant to the Offer, the stockholder is required
to notify the Depositary of such stockholder's correct TIN by completing a
Substitute Form W-9 certifying (a) that the TIN provided on Substitute Form W-9
is correct (or that such stockholder is awaiting a TIN), and (b) that (i) such
stockholder has not been notified by the Internal Revenue Service that such
stockholder is subject to backup withholding as a result of a failure to report
all interest or dividends or (ii) the Internal Revenue Service has notified
such stockholder that such stockholder is no longer subject to backup
withholding.
 
  The stockholder is required to give the Depositary the social security number
or employee identification number of the record holder of the Shares tendered
hereby. If the Shares are in more than one name or are not in the name of the
actual owner, consult the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional guidance on which
number to report. The tendering stockholder may write "applied for" on the box
in Part I of the Substitute Form W-9 if the tendering stockholder has not been
issued a TIN and has applied for a TIN or intends to apply for a TIN in the
near future. If "applied for" is written in the box in Part I, the stockholder
or other payee must also complete the Certification of the form in order to
avoid backup withholding. Notwithstanding that the
 
                                       9

tendering stockholder writes "applied for" in the box in Part I and completes
the Certification, the Depositary will retain 31% of all payments made prior to
the time a properly certified TIN is provided to the Depositary. The Depositary
will refund any amounts so retained if the Depositary receives a properly
certified TIN from the tendering stockholder within 60 days after the date of
the original Substitute Form W-9 (and such tendering stockholder was not
subject to backup withholding during that period).
 
  11. Lost, Destroyed or Stolen Certificates. If any certificate(s)
representing Shares has been lost, destroyed or stolen, the stockholder should
promptly notify the Depositary. The stockholder will then be instructed as to
the steps that must be taken in order to replace the certificate(s). This
Letter of Transmittal and related documents cannot be processed until the
procedures for replacing lost or destroyed certificates have been followed.
 
  IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE THEREOF), PROPERLY
COMPLETED AND DULY EXECUTED, TOGETHER WITH CERTIFICATES OR CONFIRMATION OF
BOOK-ENTRY TRANSFER AND ALL OTHER REQUIRED DOCUMENTS OR THE NOTICE OF
GUARANTEED DELIVERY, MUST BE RECEIVED BY THE DEPOSITARY AT ONE OF ITS ADDRESSES
SET FORTH HEREIN PRIOR TO THE EXPIRATION DATE.

  er, if after being notified by the IRS that you were subject to backup
  withholding you received another notification from the IRS that you are
  no longer subject to backup withholding, do not cross out item (2). (Also

To Our Clients:
 
  Enclosed for your consideration is an Offer to Purchase dated December 16,
1994 (the "Offer to Purchase") and a Letter of Transmittal (which, together
with any amendments or supplements thereto, constitute the "Offer") relating to
an offer by The Williams Companies, Inc., a Delaware corporation (the
"Purchaser"), to purchase up to 24,600,000 shares of Common Stock, par value
$0.50 per share (the "Shares"), of Transco Energy Company, a Delaware
corporation (the "Company"), and the attached common share purchase rights (the
"Company Rights" and, unless the context otherwise requires, deemed to be
included in all references to "Shares"), at a purchase price of $17.50 per
Share, net to the seller in cash without interest, upon the terms and subject
to the conditions set forth in the Offer. We are the holder of record of the
Shares held by us for your account. A TENDER FOR SUCH SHARES CAN BE MADE ONLY
BY US AS THE HOLDER OF RECORD AND PURSUANT TO YOUR INSTRUCTIONS. THE LETTER OF
TRANSMITTAL IS FURNISHED TO YOU FOR YOUR INFORMATION ONLY AND CANNOT BE USED BY
YOU TO TENDER SHARES HELD BY US FOR YOUR ACCOUNT.
 
  We request instructions as to whether you wish to tender any or all of such
Shares held by us for your account, pursuant to the terms and conditions set
forth in the Offer.
 
  Your attention is invited to the following:
 
    1. The tender price is $17.50 per Share, net to the seller in cash
       without interest. The redemption amount of $.05 per Company Right to
       be paid in redemption of the Company Rights attached to Shares
       acquired pursuant to the Offer will be paid to and retained by the
       Purchaser.
 
    2. The Offer, proration period and withdrawal rights will expire at
       12:00 midnight, New York City time, on Tuesday, January 17, 1995,
       unless the Offer is extended.
 
    3. The Offer is being made for up to 24,600,000 Shares. If more than
       24,600,000 Shares are validly tendered prior to the Expiration Date
       (as defined in the Offer to Purchase) and not withdrawn, the
       Purchaser will, upon the terms and subject to the conditions of the
       Offer, accept such Shares for payment on a pro rata basis, with
       adjustments to avoid purchases of fractional shares, based upon the
       number of Shares validly tendered prior to the Expiration Date and
       not withdrawn.
 
    4. The Offer is conditioned upon, among other things, there being
       validly tendered and not withdrawn prior to the expiration of the
       Offer at least 20,900,000 Shares (representing approximately 51% of
       the presently outstanding Shares) and the waiting period under the
       Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended,
       having expired or been terminated.

    5. Stockholders who tender Shares will not be obligated to pay
       brokerage commissions, solicitation fees or, except as set forth in
       Instruction 6 of the Letter of Transmittal, transfer taxes on the
       purchase of Shares by the Purchaser pursuant to the Offer.
 
  The Purchaser is not aware of any state where the making of the Offer is
prohibited by administrative or judicial action pursuant to any valid state
statute. If the Purchaser becomes aware of any valid state statute prohibiting
the making of the Offer or the acceptance of Shares pursuant thereto, the
Purchaser will make a good faith effort to comply with any such state statute.
If, after such good faith effort, the Purchaser cannot comply with any such
state statute, the Offer will not be made to (nor will tenders be accepted from
or on behalf of) the holders of Shares in such state. In any jurisdiction where
the securities, blue sky or other laws require the Offer to be made by a
licensed broker or dealer, the Offer will be deemed to be made on behalf of the
Purchaser by the Dealer Manager or one or more registered brokers or dealers
licensed under the laws of such jurisdiction.
 
  If you wish to have us tender any or all of your Shares, please complete,
sign and return to us the form set forth below. An envelope to return your
instructions to us is enclosed. Your instructions to us should be forwarded in
ample time to permit us to submit a tender on your behalf prior to the
expiration of the Offer. If you authorize the tender of your Shares, all such
Shares will be tendered unless otherwise specified on the instruction form set
forth below.

  GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION NUMBER ON SUBSTITUTE
                                    FORM W-9
 
SECTION REFERENCES ARE TO THE INTERNAL REVENUE CODE.
 
  Purpose of Form--A person who is required to file an information return with
the IRS must obtain your correct TIN to report income paid to you, real estate
transactions, mortgage interest you paid, the acquisition or abandonment of
secured property, or contributions you made to an IRA. Use Form W-9 to furnish
your correct TIN to the requester (the person asking you to furnish your TIN)
and, when applicable, (1) to certify that the TIN you are furnishing is correct
(or that you are waiting for a number to be issued), (2) to certify that you
are not subject to backup withholding, and (3) to claim exemption from backup
withholding if you are an exempt payee. Furnishing your correct TIN and making
the appropriate certifications will prevent certain payments from being subject
to backup withholding.
 
  Note: If a requester gives you a form other than W-9 to request your TIN, you
must use the requester's form.
 
  How To Obtain a TIN--If you do not have a TIN, apply for one immediately. To
apply, get Form SS-5, Application for a Social Security Card (for individuals),
from your local office of the Social Security Administration, or Form SS-4,
Application for Employer Identification Number (for businesses and all other
entities), from your local IRS office.
 
  To complete Form W-9 if you do not have a TIN, write "Applied for" in the
space for the TIN in Part I, sign and date the form, and give it to the
requester. Generally, you will then have 60 days to obtain a TIN and furnish it
to the requester. If the requester does not receive your TIN within 60 days,
backup withholding, if applicable, will begin and continue until you furnish
your TIN to the requester. For reportable interest or dividend payments, the
payer must exercise one of the following options concerning backup withholding
during this 60-day period. Under option (1), a payer must backup withhold on
any withdrawals you make from your account after 7 business days after the
requester receives this form back from you. Under option (2), the payer must
backup withhold on any reportable interest or dividend payments made to your
account, regardless of whether you make any withdrawals. The backup withholding
under option (2) must begin no later than 7 business days after the requester
receives this form back. Under option (2), the payer is required to refund the
amounts withheld if your certified TIN is received within the 60-day period and
you were not subject to backup withholding during that period.
 
  Note: Writing "Applied for" on the form means that you have already applied
for a TIN OR that you intend to apply for one in the near future.
 
  As soon as you receive your TIN, complete another Form W-9, include your TIN,
sign and date the form, and give it to the requester.
 
  What Is Backup Withholding?--persons making certain payments to you after
1992 are required to withhold and pay to the IRS 31% of such payments under
certain conditions. This is called "backup withholding". Payments that could be
subject to backup withholding include interest, dividends, broker and barter
exchange transactions, rents, royalties, nonemployee compensation, and certain
payments from fishing boat operators, but do not include real estate
transactions.
 
  If you give the requester your correct TIN, make the appropriate
certifications, and report all your taxable interest and dividends on your tax
return, your payments will not be subject to backup withholding. Payments you
receive will be subject to backup withholding if:
 
    1. You do not furnish your TIN to the requester, or
 
    2. The IRS notifies the requester that you furnished an incorrect TIN, or

    3. You are notified by the IRS that you are subject to backup withholding
  because you failed to report all your interest and dividends on your tax
  return (for reportable interest and dividends only), or
 
    4. You do not certify to the requester that you are not subject to backup
  withholding under 3 above (for reportable interest and dividend accounts
  opened after 1983 only), or
 
    5. You do not certify your TIN. This applies only to reportable interest,
  dividend, broker, or barter exchange accounts opened after 1983, or broker
  accounts considered inactive in 1983.
 
  Except as explained in 5 above, other reportable payments are subject to
backup withholding only if 1 or 2 above applies. Certain payees and payments
are exempt from backup withholding and information reporting. See Payees and
Payments Exempt From Backup Withholding, below, and Example Payees and Payments
under Specific Instructions, below, if you are an exempt payee.

Company announced today that they have entered into a merger agreement. Under 
the agreement, Williams will make a cash tender offer to acquire up to 24.6 
million shares, or 60 percent, of Transco's common stock and related common 
stock purchase rights for $17.50 per share and right. The cash tender offer will

directors and by Transco's board of directors.

The total value of the cash tender offer and merger, including the exchange of
new series of Williams convertible preferred stock for Transco's two outstanding

Transco's common stock on Friday Dec. 9, 1994.

Under the agreement, Williams will begin the cash tender offer on Friday, Dec. 
16, which will expire at midnight, Eastern Standard Time, On Jan. 17, 1995,

other customary conditions. Following completion of the tender offer, a newly 
formed subsidiary of Williams will be merged into Transco, with Transco

   Williams makes SEC filing to purchase up to 60 percent of Transco's stock

     TULSA -- The Williams Companies, Inc. today filed with the Securities and 
Exchange Commission definitive documents pursuant to which it is making a cash 
tender offer to acquire up to 24.6 million shares, or about 60 percent, of 
Transco Energy Company's common stock and common stock purchase rights for 
$17.50 per share and right.

     The tender offer, announced Monday, begins today and runs through midnight,
Eastern time, on Jan. 17, 1995, unless extended by Williams. Williams' 
obligation to purchase shares pursuant to the tender offer is subject to, among 
other things, the valid tender and non-withdrawal at the expiration date of the 
offer at least 20.9 million shares, or approximately 51 percent of Transco's 
common stock.

     The information agent for the tender offer is Morrow & Co., Inc., 
(800)566-9058. The dealer-manager is Smith Barney Inc. (212)698-3612.

     When successful, the tender offer will be followed by the merger of a 
subsidiary of Williams with Transco, with Transco ultimately becoming a wholly 
owned subsidiary of Williams.

     The boards of directors of both companies unanimously approved the 
transaction at separate meetings on Dec. 11. The merger could be completed as 
soon as the end of the first quarter of 1995. 

     "The offer documents are being mailed to Transco shareholders, and any 
Transco shareholder having questions about the offer or needing assistance is 
encouraged to contact Morrow & Co. or Smith Barney," said Keith E. Baily, 
chairman, president and chief executive officer of Williams. 

     Bailey noted there has been considerable discussion in the investment and 
natural gas communities about the pending acquisition by Williams, which 
operates three interstate natural gas

                                       1

pipelines, major natural gas gathering and processing facilities and other gas 
assets in America's West, of Transco, which operates two major interstate gas 
systems east of the Mississippi River that serve the Midwest, South, Southeast 
and Northeast.

     He also said both companies' initial limited ability to fully discuss 
details of why both boards enthusiastically supported the transaction has been 
partially eased due to today's filing, but is still somewhat restricted due to 
certain laws and regulations.

     "I can say that the strategic fit of the gas systems of these two companies
is outstanding," Bailey said. "The combined companies' pipeline systems have 
access to the premier natural gas supply areas in North America -- Oklahoma, 
Kansas, Texas, the Rockies, the San Juan Basin and western Canada and the Gulf 
Coast.

     "The combined companies would put most of the vital natural gas markets in
the country -- from California to New York -- within realistic reach of the 
longest-lived, lowest-cost gas supplies in America, "he said. "I really see this
as a case of 'one-plus-one equals three' for us, and for producers and 
consumers."

     The documents filed with the SEC today say that Williams plans to "maintain
and expand" the existing core natural gas businesses of Transco and to "promptly
pursue" new business opportunities made available as a result of the merger, 
which include expanding development of market projects in Transco's Northeast 
and Southeast market areas.

     "Due to Transco's highly leveraged balance sheet, it has been unable over 
the past several years to take advantage of numerous opportunities in the 
fast-growing markets it serves and to build on its competitive edge," Bailey 
said. "This is juxtaposed to Williams' demonstrated track record over the past 
several years in the West, where we have committed the talent and capital to 
fully and efficiently compete for all of the demand within reach."

     He noted that natural gas demand in the area of the country served by 
Transco's system is growing significantly faster than the national average.

     He said Williams expects to be able to support the capital investment 
necessary to aggressively pursue opportunities in the eastern U.S. as well as 
"opportunities to provide Transco's markets with access to the long-lived 
supplies attached to our existing systems."

     Bailey noted it has long been a stated strategic goal of Williams to gain 
effective access to the same markets served by Transco.

     "We would immediately begin seeking additional investment opportunities 
across Transco's service area in both regulated and unregulated areas, and are 
very optimistic that we will be able to add substantially to projects already 
identified by Transco," he said.

     Bailey said much of Williams' earnings growth is linked to the company's
ability to grow

                                      2 

 
its asset base.

     "We believe the capital opportunities resulting from this transaction can 
be fully exploited without impacting our existing capital programs, thus 
accelerating our rate of capital deployment. Further developing opportunity in 
Transco's service area should, in turn, stimulate additional investments across 
our existing natural gas businesses.

     "To best accomplish our objectives, we will also move to overhaul the 
capital structure of Transco and its pipelines as quickly as possible," Bailey 
said. "Among the many things we intend to accomplish is to eliminate or modify 
some or all of the more onerous restrictions in Transco's financing agreements. 
We would expect the cost of financing for the combined company to improve due to
Williams' investment-grade status.

     "This should result in rate-making flexibility in Tranco's pipeline 
operations," he said.

     Bailey also said both companies' possess active marketing, price risk 
management and information-based products and services that, when given the 
opportunity to compete for new business around an expanded platform of pipeline 
systems, "should add an additional element to the value of the transaction."

     Although specific decisions have not been made, he said Williams expects to
aggressively continue divesting non-core assets.

     The Williams Companies, listed on the New York Stock Exchange under the

                                      of
                            Transco Energy Company
                                      at
                             $17.50 Net Per Share

                         The Williams Companies, Inc.

     The Williams Companies, Inc., a Delaware corporation (the "Purchaser"), is
offering to purchase up to 24,600,000 shares of Common Stock, par value $0.50
per share (the "Shares"), of Transco Energy Company, a Delaware corporation (the
"Company"), together with the attached common share purchase rights (the
"Company Rights"), at a price of $17.50 per Share (and attached Company Right),
net to the seller in cash, upon the terms and subject to the conditions set
forth in the Offer to Purchase dated December 16, 1994 (the "Offer to Purchase")
and in the related Letter of Transmittal (together, the "Offer"). The Company
has agreed in the Merger Agreement (as defined below) to effect a redemption of
the Company Rights for $.05 per Company Right immediately prior to the
Purchaser's acceptance for payment of Shares pursuant to the Offer. The
redemption price in respect of Company Rights attached to Shares purchased
pursuant to the Offer will be paid to and retained by the Purchaser. Unless the
context otherwise requires, references herein to "Shares" shall be deemed to
include the attached "Company Rights." Following the Offer, the Purchaser
intends to effect the Merger described below.

- --------------------------------------------------------------------------------
THE OFFER, PRORATION PERIOD AND WITHDRAWAL RIGHTS WILL EXPIRE at 12:00 MIDNIGHT,
NEW YORK CITY TIME, ON TUESDAY, JANUARY 17, 1995, UNLESS  THE OFFER IS EXTENDED.
- --------------------------------------------------------------------------------

     The Offer is conditioned upon, among other things, at least 20,900,000
Shares (representing approximately 51% of the presently outstanding Shares)
being validly tendered and not withdrawn prior to the expiration of the Offer.

     The purpose of the Offer is to acquire 24,600,000 Shares as a first step in
acquiring the entire equity interest in the Company. The Offer is being made
pursuant to an Agreement and Plan of Merger, dated as of December 12, 1994 (the
"Merger Agreement"), among the Purchaser, WC Acquisition Corp., a Delaware
corporation and a wholly-owned subsidiary of the Purchaser ("Sub"), and the
Company. The Merger Agreement provides, among other things, that as soon as
practicable after the purchase of Shares pursuant to the Offer, the approval of
the stockholders of the Company and the satisfaction of certain other
conditions, Sub will be merged with and into the Company (the "Merger").
Following consummation of the Merger, the Company will continue as the surviving
corporation (the "Surviving Corporation") and as a subsidiary of the Purchaser.
At the effective time of the Merger (the "Effective Time"), each Share issued
and outstanding immediately prior to the Effective Time (other than Shares held
in the treasury of the Company, Shares owned by the Purchaser or any direct or
indirect wholly-owned subsidiary of the Purchaser, or dissenting Shares
(collectively, "Retired or Dissenting Shares")) will be converted into the right
to receive .625 shares of Common Stock, par value $1.00 per share, of the
Purchaser (the "Purchaser Common Stock"), including .3125 preferred stock
purchase rights attached thereto (the "Purchaser Rights"). In the event that
less than 24,600,000 Shares, but at least 20,900,000 Shares, are purchased
pursuant to the Offer, each Share that is issued and outstanding immediately
prior to the Effective Time (other than Retired or Dissenting Shares) will be
converted into the right to receive (i) an amount in cash (the "Per Share Cash
Amount") equal to (x) the excess of (A) the product of (1) $17.50 or such higher
amount as may be paid in the Offer (the "Per Share Amount") and (2) the excess
of 24,600,000 over the number of Shares purchased pursuant to the Offer, over
(B) the aggregate amount paid in the redemption of Company Rights not acquired
pursuant to the Offer, divided by (y) the number of Shares outstanding
immediately prior to the Effective Time (other than Retired or Dissenting
Shares) and (ii) the fraction of a share of Purchaser Common Stock equal to (A)
the product of (1) .625 and (2) the excess of the Per Share Amount over the Per
Share Cash Amount, divided by (B) the Per Share Amount (such fractional amount
of a share of Purchaser Common Stock, the "Conversion Number"), together with a
fraction of attached Purchaser Rights equal to the Conversion Number divided by
2. The Offer does not constitute an offer to sell or a solicitation of an offer
to buy any securities of the Purchaser. Such an offer may be made only pursuant
to a prospectus.

     The Board of Directors of the Company has unanimously (with one director
absent) determined that the Offer and the Merger, taken together, are fair to,
and in the best interests of, the stockholders of the Company, and recommends
that holders of Shares accept the Offer and tender their Shares pursuant to the
Offer.

     For purposes of the Offer, the Purchaser will be deemed to have accepted
for payment (and thereby purchased) Shares validly tendered and not properly
withdrawn as, if and when the Purchaser gives oral or written notice to Chemical
Bank (the "Depositary") of the Purchaser's acceptance for payment of such Shares
pursuant to the Offer. Upon the terms and subject to the conditions of the
Offer, payment of Shares accepted for payment pursuant to the Offer will be made
by deposit of the purchase price therefor with the Depositary, which will act as
agent for tendering stockholders for the purpose of receiving payments from the
Purchaser and transmitting such payments to tendering stockholders whose Shares
have been accepted for payment. Under no circumstances will interest on the
purchase price for Shares be paid, regardless of any delay in making such
payment. In all cases, payment for Shares tendered and accepted for payment
pursuant to the Offer will be made only after timely receipt by the Depositary
of (i) the certificates evidencing such Shares (the "Share Certificates") or
timely confirmation of a book-entry transfer of such Shares, if such procedure
is available, into the Depositary's account at one of the Book-Entry Transfer

Facilities (as defined in Section 2 of the Offer to Purchase) pursuant to the
procedure set forth in Section 3 of the Offer to Purchase, (ii) the Letter of
Transmittal (or facsimile thereof), properly completed and duly executed, with
any required signature guarantees, or an Agent's Message (as defined in Section
2 of the Offer to Purchase) and (iii) any other documents required under the
Letter of Transmittal.

     The Purchaser expressly reserves the right, in its sole discretion (but
subject to the terms and conditions of the Merger Agreement), at any time and
from time to time, to extend for any reason the period of time during which the
Offer is open, including the occurrence of any condition specified in Section 14
of the Offer to Purchase, by giving oral or written notice of such extension to
the Depositary. Any such extension will be followed as promptly as practicable
by public announcement thereof, such announcement to be made no later than 9:00
a.m., New York City time, on the next business day after the previously
scheduled expiration date of the Offer. During any such extension, all Shares
previously tendered and not withdrawn will remain subject to the Offer, subject
to the rights of a tendering stockholder to withdraw such stockholder's Shares.

     If more than 24,600,000 Shares are validly tendered prior to the Expiration
Date (as defined in the Offer to Purchase) and not withdrawn, the Purchaser
will, upon the terms and subject to the conditions of the Offer, accept such
Shares for payment on a pro rata basis, with adjustments to avoid purchases of
fractional Shares, based upon the number of Shares validly tendered prior to the
Expiration Date and not withdrawn.

     Tenders of Shares made pursuant to the Offer are irrevocable except that
such Shares may be withdrawn at any time prior to 12:00 Midnight, New York City
time, on Tuesday, January 17, 1995 (or the latest time and date at which the
Offer, if extended by the Purchaser, shall expire) and, unless theretofore
accepted for payment by the Purchaser pursuant to the Offer, may also be
withdrawn at any time after February 13, 1995. For a withdrawal to be effective,
a written, telegraphic or facsimile transmission notice of withdrawal must be
timely received by the Depositary at one of its addresses set forth on the back
cover of the Offer to Purchase. Any such notice of withdrawal must specify the
name of the person who tendered the Shares to be withdrawn, the number of Shares
to be withdrawn and the name of the registered holder of such Shares, if
different from that of the person who tendered such Shares. If Share
Certificates evidencing Shares to be withdrawn have been delivered or otherwise
identified to the Depositary, then, prior to the release of such Share
Certificates, the serial numbers shown on such Share Certificates must be
submitted to the Depositary and the signature(s) on the notice of withdrawal
must be guaranteed by an Eligible Institution (as defined in Section 3 of the
Offer to Purchase), unless such Shares have been tendered for the account of an
Eligible Institution. If Shares have been tendered pursuant to the procedure for
book-entry transfer as set forth in Section 3 of the Offer to Purchase, any
notice of withdrawal must specify the name and number of the account at the 
Book-Entry Transfer Facility to be credited with the withdrawn Shares. All 
questions as to the form and validity (including the time of receipt) of any 
notice of withdrawal will be determined by the Purchaser, in its sole
discretion, whose determination will be final and binding.

     The information required to be disclosed by Rule 14d-6(e)(1)(vii) of the
General Rules and Regulations under the Securities Exchange Act of 1934, as
amended, is contained in the Offer to Purchase and is incorporated herein by
reference.

     The Company has provided the Purchaser with the Company's stockholder list
and security position listings for the purpose of disseminating the Offer to
holders of Shares. The Offer to Purchase and the related Letter of Transmittal
will be mailed to record holders of Shares whose names appear on the Company's
stockholder list and will be furnished to brokers, dealers, commercial banks,
trust companies and similar persons whose names, or the names of whose nominees,
appear on the stockholder list or, if applicable, who are listed as participants
in a clearing agency's security position listing for subsequent transmittal to
beneficial owners of Shares.

     The Offer to Purchase and the related Letter of Transmittal contain
important information which should be read before any decision is made with
respect to the Offer.

     Questions and requests for assistance or for additional copies of the Offer
to Purchase and the related Letter of Transmittal and other tender offer
materials may be directed to the Information Agent or the Dealer Manager as set
forth below, and copies will be furnished promptly at the Purchaser's expense.
No fees or commissions will be paid to brokers, dealers or other persons (other
than the Information Agent and the Dealer Manager) for soliciting tenders of
Shares pursuant to the Offer.

Ladies and Gentlemen:

     Based on our discussions concerning the proposed acquisition of a publicly-
held Delaware corporation code-named "Green" (the "Company") by The Williams
                                                   -------                  
Companies, Inc., a Delaware corporation ("Williams") (the "Transaction"),

Citibank, N.A. ("Citibank"), Bank of America National Trust and Savings

Association ("BofA"), Chemical Bank ("Chemical") and Canadian Imperial Bank of
              ----                    --------                                
Commerce ("CIBC") are pleased to provide you with financing commitments for, and
           ----                                                                 
to agree to act as co-administrative agents (the "Administrative Agents") in
                                                  ---------------------     
connection with, the senior debt facility described below and on the attached
Annex (the "Senior Facility").
            ---------------   

     As the Administrative Agents understand the transaction, you will, pursuant
to a merger agreement to be entered into with the Company, offer to acquire
through a tender offer (the "Tender Offer") up to 60% of the shares of the

previously disclosed to us, but in any event for not fewer than sufficient
shares of Company Stock to enable Williams, voting without any other
shareholders of the Company, to approve a merger of a newly formed subsidiary of
Williams with the Company.  As promptly as practicable after the closing of the
Tender Offer, such subsidiary will consummate a merger (the "Merger") with the
                                                             ------           
Company in which the Company will be the surviving corporation (the "Surviving
                                                                     ---------

Tender Offer and the Merger shall not exceed 60% of such Stock, with the balance
of such Stock to be payable solely in common stock of Williams.

     You have asked that Citibank, BofA, Chemical and CIBC each provide you with
a commitment in the amount of $300,000,000, for aggregate commitments of
$1,200,000,000, representing the entire amount of the Senior Facility.

                                       2

     Subject to the satisfaction of the conditions contained in this Commitment
Letter and your acceptance hereof, Citibank, BofA, Chemical and CIBC each
commits to lend up to $300,000,000 of the financing for the Transaction, on the
terms and conditions referred to herein and in the attached Annex.

     Please note, however, that the terms and conditions of these commitments
are not limited to those set forth herein or in the attached Annex.  Those
matters that are not covered or made clear herein or in the attached Annex are
subject to mutual agreement of the parties.  The terms and conditions of these
commitments may be modified only in writing.  In addition, these commitments are

loan documentation, including a credit agreement incorporating substantially the
terms and conditions outlined herein and in the attached Annex, (b) the absence
of (i) a material adverse change in the business, condition (financial or
otherwise), operations, performance, properties or prospects of Williams, the
Company or any of their subsidiaries since December 31, 1993, provided that the
                                                              --------         
non-occurrence of the WilTel Sale (as defined in the attached Annex) shall not,
in and of itself, be deemed to constitute such a material adverse change, and
(ii) any material adverse change in loan syndication or financial or capital
market conditions generally from those currently in effect, and (c) the accuracy
and completeness of all representations that you make to us and all information
that you furnish to us in connection with these commitments.  The respective
commitments of Citibank, BofA, Chemical and CIBC set forth in this letter will
terminate on January 31, 1995 or such later date as may be agreed between the
Administrative Agents and the Borrower (provided that in no event shall the
commitments hereunder be extended beyond March 31, 1995), unless the initial
borrowing under the Senior Facility shall have occurred on or before such date.

     In addition to the fees described on the attached Annex, you agree to pay
the nonrefundable fees set forth in the fee letter dated the date hereof with
Citibank and Citicorp Securities, Inc., an affiliate of Citibank and the fee
letter dated the date hereof with Citibank, BofA, Chemical and CIBC,

                    -----------   

     Upon notice to you from the Arrangers (as defined under the paragraph
"Arrangers" in the attached Annex) of their intention to commence a general
- ----------                                                                 
syndication of the Senior Facility, the Arrangers will syndicate the financing
for the Transaction to additional Lenders with a corresponding reduction in the
commitments of the Administrative Agents.   Citicorp Securities will manage all
aspects of the syndication in consultation with the other Arrangers, including
the timing of all offers to potential Lenders and the acceptance of commitments,
the amounts offered and the compensation provided.

     You agree to take all action as the Arrangers may reasonably request to
assist it in forming a syndicate acceptable to them.  Your assistance in forming
such a syndicate shall include but not be limited to: (i) making senior
management and representatives of the

                                       3

Company available to participate in information meetings with potential Lenders
at such times and places as the Arrangers may reasonably request; (ii) using
your best efforts to ensure that the syndication efforts benefit from your
lending relationships; and (iii) providing the Arrangers with all information
reasonably deemed necessary by them to successfully complete the syndication,
including, without limitation, a summary of the operating prospects (including
financial projections) of the Company.

     Upon notice to you from the Arrangers of their intention to commence a
general syndication of the Senior Facility, to ensure an orderly and effective
syndication of the Senior Facility, you agree that until the termination of the
syndication (as evidenced by written notification received by you from the
Arrangers), you will not, and will not permit any of your affiliates to,
syndicate or issue, attempt to syndicate or issue, announce or authorize the
announcement of the syndication or issuance of, or engage in discussions
concerning the syndication or issuance of, any debt facility or debt security
(including any renewals thereof) in the commercial bank market, without the
prior written consent of the Arrangers; provided, however, that the foregoing
                                        --------  -------                    
shall not limit your ability to issue commercial paper, other short-term debt
programs currently in place, equity or public debt securities or incur debt
pursuant to the $100,000,000 production payment financing currently contemplated
with NationsBank, N.A. or in connection with the construction loan contemplated
to be borrowed from the First National Bank of Omaha for purposes of
constructing an ethanol plant.

     You agree that no additional agents, co-agents or arrangers will be
appointed, or other titles conferred, without the consent of the Arrangers.  You
agree that no Lender will receive any compensation of any kind for its
participation in the Senior Facility, except as expressly provided for in the
Commitment Letter or the Fee Letters.

     You agree to indemnify and hold harmless each Administrative Agent, each
Arranger, each Lender (as defined under the paragraph "Lenders" in the attached
                                                       -------                 
Annex) and each of their affiliates and their officers, directors, employees,
agents and advisors (each, an "Indemnified Party") from and against any and all
                               -----------------                               
claims, damages, losses, liabilities and expenses (including, without
limitation, reasonable fees and expenses of counsel) that may be incurred by or
asserted or awarded against any Indemnified Party, in each case arising out of
or in connection with or by reason of, or in connection with the preparation for
a defense of, any investigation, litigation or proceeding arising out of,
related to or in connection with the Transaction or any similar transaction and
any of the other transactions contemplated thereby or the Senior Facility and
any other financings or any use made or proposed to be made with the proceeds
thereof, whether or not such investigation, litigation or proceeding is brought
by you, your shareholders or creditors or an Indemnified Party or an Indemnified
Party is otherwise a party thereto and whether or not the Transaction is
consummated, except to the extent such claim, damage, loss, liability or expense
is found in a final, non-appealable judgment by a court of competent
jurisdiction to have resulted from such Indemnified Party's

                                       4

gross negligence or willful misconduct.  You also agree that no Indemnified
Party shall have any liability (whether direct or indirect, in contract or tort
or otherwise) to you or your security holders or creditors arising out of,
related to or in connection with the Transaction, except (a) to the extent that
such liability is found in a final non-appealable judgment by a court of
competent jurisdiction to have resulted from such Indemnified Party's gross
negligence or willful misconduct and (b) for direct, as opposed to
consequential, damages for breach of the obligations of the Administrative
Agents hereunder to negotiate in good faith definitive documentation for the
financing for the Transaction on the terms set forth herein and in the attached
Annex.

     You should be aware that the Administrative Agents or their respective
affiliates may be providing financing or other services to parties whose
interests may conflict with yours.   However, be assured that, consistent with
the longstanding policy of each of the Administrative Agents to hold in
confidence the affairs of their respective customers, the Administrative Agents
will not furnish confidential information obtained from you to any of their
respective other customers.  By the same token, the Administrative Agents will
not make available to you confidential information that any of them has obtained
or may obtain from any other customer.

     You agree that this Commitment Letter is for your confidential use only and
will not be disclosed by you to any person other than your accountants,
attorneys and other advisors, and then only in connection with the Transaction
and on a confidential basis, except that, following your acceptance hereof, you
may make public disclosure of the existence and amount of the commitments of the
Administrative Agents hereunder, you may file a copy of this Commitment Letter
in any public record in which it is required by law to be filed and you may make
such other public disclosures of the terms and conditions hereof as you are
required by law, in the opinion of your counsel, to make.

     In issuing their respective commitments, the Administrative Agents are
relying on the accuracy of the information furnished to them by you or on your
behalf.  The obligations of the Administrative Agents under this Commitment
Letter and of any Lender that issues a commitment for the Senior Facility are
made solely for your benefit and may not be relied upon or enforced by any other
person or entity.

     This Commitment Letter shall be governed by, and construed in accordance
with, the laws of the State of New York.  Delivery of an executed counterpart of
this Commitment Letter by telecopier shall be effective as delivery of a
manually executed counterpart of this Commitment Letter.  You and each of the
Administrative Agents hereby irrevocably waive all right to trial by jury in any
action, proceeding or counterclaim (whether based on contract, tort or
otherwise) arising out of or relating to this Commitment Letter, the
transactions contemplated hereby or the actions of any Administrative Agent in
the negotiation, performance or enforcement hereof.

                                       5

     Please evidence your acceptance of the provisions of this Commitment
Letter, the attached Annex and the other matters referred to above by signing
the enclosed copy of this Commitment Letter and returning it to the undersigned
at or before 10:00 A.M. (New York City time) on December 12, 1994, the time at
which the commitments of Citibank, BofA, Chemical and CIBC set forth above (if
not so accepted prior thereto) will expire.  By accepting this Commitment
Letter, you agree to pay that portion of the respective fees then payable under
the Fee Letters at or before 5:00 P.M. (New York City time) on December 12,
1994.

                    CAPITALIZED TERMS NOT OTHERWISE DEFINED
                   HEREIN HAVE THE MEANINGS SET FORTH IN THE
                    LETTER TO WHICH THIS ANNEX IS ATTACHED

                    manage all aspects of the syndication of the Senior

                    Lenders and the acceptance of commitments, the amounts
                    offered and the compensation provided.  If a syndication is

                    that the syndication of the Senior Facility has been
                    completed, no Lender may assign any part of its share
                    thereof to any other potential Lender.  Following receipt of
                    notice from the Arrangers that the syndication of the Senior
                    Facility has been completed, each Lender may assign all or

                    institutions that are Eligible Assignees (to be defined in
                    the loan documentation), and upon such assignment such
                    financial institutions shall become Lenders for all purposes
                    under the loan documentation.  The Borrower shall cooperate
                    with the Arrangers in the syndication of the Senior Facility
                    and shall provide and cause its

                    reduced at closing by the amount of the commitments to
                    remain outstanding after the closing under the $600,000,000

                    Telecommunications Group, Inc., a wholly owned subsidiary of

                    then payable under the U.S.$400,000,000 Credit Agreement
                    dated as of September 2, 1994 between WTG Holdings, Inc. and
                    Citibank) or from the sale of assets (other than the sale of
                    inventory in the ordinary course of business) in any
                    transaction or series of transactions in an amount exceeding
                    $25,000,000 shall be applied to the permanent reduction of
                    the Senior Facility.

                    Eurodollar Rate (adjusted for reserves).  Interest based on
                    the Base Rate shall be payable quarterly in arrears.

                    Interest based on the Eurodollar Rate shall be payable in

                    three-month certificates of deposit of major U.S. money
                    market banks, as determined weekly by Citibank and adjusted
                    for the cost of reserves and estimated insurance assessments
                    from the FDIC and (iii) a rate equal to 1/2 of 1% per annum
                    above the weighted average of the rates on overnight Federal
                    funds transactions with members of the Federal Reserve
                    System arranged by Federal funds brokers, as determined for
                    any day by Citibank.

                    The "Applicable Margin" means 0% per annum for Base Rate
                    borrowings and a percentage per annum for Eurodollar Rate
                    borrowings based on the Borrower's public debt rating as set
                    forth in the Existing Agreement.

                    per annum.

                    rating as set forth in the Existing Agreement, to be paid on
                    the unused portion of each Lender's commitment from the date
                    of acceptance of such Lender's commitment, payable on (a)
                    the closing of the Senior Facility and quarterly in arrears
                    thereafter and (b) the date (whether before or after the
                    closing) of termination of the commitments.

                         Corporation Law and any supermajority charter

                         shareholders tender their Company Stock pursuant to the

                         Lenders.

                    (e)  The Borrower shall have used its best efforts to cause
                         the existing credit facilities of the Borrower and the
                         Company to be amended to permit the Transaction and the
                         other transactions contemplated hereby on terms
                         satisfactory to the Lenders pursuant to documentation
                         satisfactory in form and substance to the Lenders, and
                         such existing credit facilities shall have been so

                    (f)  The Lenders shall be satisfied with the corporate and
                         legal structure and capitalization of the Borrower,

                                       6

                    (g)  There shall have occurred no material adverse change in
                         the business, condition (financial or otherwise),

                         Borrower, the Company or any of their subsidiaries,
                         provided that the non-occurrence of the WilTel Sale
                         shall not, in and of itself, be deemed to constitute
                         such a material adverse change, and all information
                         provided by or on behalf of the Borrower to the Lenders
                         prior to their commitment (the "Pre-Commitment

                         aspects.

                    (h)  There shall exist no action, suit, investigation,
                         litigation or proceeding pending or threatened in any
                         court or before any arbitrator or governmental
                         instrumentality that (i) would be reasonably likely to
                         have a material adverse effect on the business,
                         condition (financial or otherwise), operations,
                         performance, properties or prospects of the Borrower or
                         any of its subsidiaries other than the litigation
                         described in the Pre-Commitment Information (the
                         "Disclosed Litigation") (it being understood that no
                         determination has yet been made as to whether such
                         Disclosed Litigation would be reasonably likely to have
                         such a material adverse effect) or (ii) purports to
                         affect the Transaction or the Senior Facility, and
                         there shall have been no adverse change in the status,
                         or financial effect on the Borrower or any of its
                         subsidiaries, of the Disclosed Litigation from that
                         described in the Pre-Commitment Information).

                    (i)  All governmental and third party consents and approvals
                         necessary in connection with the Transaction and the
                         Senior Facility shall have been obtained (without the
                         imposition of any conditions that are not acceptable to
                         the Lenders) and shall remain in effect; all applicable
                         waiting periods shall have expired without any action
                         being taken by any competent authority; and no law or
                         regulation shall be applicable in the judgment of the
                         Lenders that restrains, prevents or imposes materially

          AGREEMENT AND PLAN OF MERGER, dated as of December 12, 1994 (this
"Agreement"), by and among The Williams Companies, Inc., a Delaware corporation
("Parent"), WC Acquisition Corp., a Delaware corporation and a wholly owned
subsidiary of Parent ("Sub"), and Transco Energy Company, a Delaware corporation
(the "Company").

          WHEREAS, the respective Boards of Directors of Parent and the Company
have determined that the acquisition of the Company by Parent would be
advantageous and beneficial to their respective corporations and stockholders,
and that such transaction is consistent with and in furtherance of such
entities' respective long-term business strategies;

          WHEREAS, in furtherance thereof, it is proposed that Parent will make
a cash tender (the "Offer") to acquire up to 24,600,000 shares of the Company's
common stock, par value $.50 per share (the "Company Common Stock"), together
with attached Company Rights (as defined in Section 4.2), for $17.50 per share
of Company Common Stock (and attached Right) (such amount, or any greater amount
per share pursuant to the Offer, being

hereinafter referred to as the "Per Share Amount"), net to the seller in cash,
in accordance with the terms and subject to the conditions provided herein and
in the Offer Documents (as defined in Section 1.1(b));

          WHEREAS, it is proposed that, following consummation of the Offer,
there be a merger of Sub with and into the Company (the "Merger") with the
Company surviving as a subsidiary of Parent (the "Surviving Corporation"); and

          WHEREAS, as a condition to the willingness of Parent to enter into
this Agreement, Parent has required that the Company agree, and in order to
induce Parent to enter into this Agreement, the Company has entered into
concurrently with the execution of this Agreement a Stock Option Agreement (the
"Stock Option Agreement") providing for a grant of an option to Parent to
purchase, at a per share price of $17.50 per share and otherwise upon the terms

                                   ARTICLE I

                               THE TENDER OFFER

          Section 1.1  The Offer.
                       --------- 

          (a)  Provided that this Agreement has not been terminated in
accordance with Section 8.1, Parent will commence the Offer as promptly as
practicable after the date hereof, but in no event later than December 16, 1994.
The obligation of Parent to accept for payment any shares of Company Common
Stock (and attached Company Rights) tendered pursuant to the Offer will be only

Parent expressly reserves the right to (i) increase the Per Share Amount or (ii)
increase on one occasion the number of shares of Company Common Stock (and
attached Company Rights) to be purchased in the Offer; provided, that (x) any
                                                       --------

the Offer beyond its then applicable expiration date in accordance with
applicable law must provide for an increase of at least 4,000,000 shares and (y)

preceding the date of public notice of the increase

                                       3

to the immediately preceding sentence, may be waived by Parent, in whole or in
part, at any time and from time to time in its discretion.  The Offer will be
made by means of an offer to purchase (the "Offer to Purchase") containing the
terms set forth in this Agreement and only the conditions set forth in Annex I
hereto.  Subject to the terms of the Offer and this Agreement and the
satisfaction of all the conditions of the Offer set forth in Annex I hereto as
of any expiration date, Parent will accept for payment and pay for all shares of

(including as an exhibit) or will incorporate by reference the Offer to Purchase
(or portions thereof) and forms of the related letter of transmittal and summary
advertisement (which Schedule 14D-1, Offer to Purchase and other documents,
together with any supplements or amendments thereto, are referred to herein
collectively as the "Offer Documents").  Parent will disseminate the Offer to
Purchase, related Letter of Transmittal and other related Offer Documents to
holders of shares of the Company Common Stock.  Each of Parent and the Company

                                       5

provided by it for use in the Offer Documents that becomes false or misleading
in any material respect and Parent will take all steps necessary to cause the
Schedule 14D-1 as so corrected to be filed with the SEC and the other Offer
Documents as so corrected to be disseminated to holders of shares of Company
Common Stock, in each case as and to the extent required by applicable law.
Parent will provide the Company and its counsel in writing with any comments
Parent or its counsel may receive from the SEC or its staff with respect to the
Offer Documents promptly after the receipt of such comments.  Parent and its
counsel will provide the Company and its counsel with a reasonable opportunity
to participate in all communications with the SEC and its staff, including any

will promptly correct any information provided by it for use in the Schedule
14D-9 that becomes false or misleading in any material respect, and the Company
will further take all steps necessary to cause the Schedule 14D-9 as so
corrected to be filed with the SEC and disseminated to holders of shares of
Company Common Stock, in each case as and to the extent required by applicable
law.  The Company will provide Parent and its counsel in writing with any

Company and its counsel will provide Parent and its counsel with a reasonable
opportunity to participate in all communications with the SEC and its staff,
including any meetings and telephone conferences relating to the Schedule 14D-9,
the Merger or this Agreement.

          (b)  The Company will (i) promptly furnish Parent with mailing labels
containing the names and addresses of all record holders of shares of Company

                                       7

after such date, together with copies of all security position listings and
computer files and all other information in the Company's control regarding the
beneficial owners of shares of Company Common Stock that Parent may reasonably
request and (ii) furnish to Parent such other assistance as Parent or its agents
may reasonably request in communicating the Offer to holders of shares of
Company Common Stock.

          (c)  Subject to the requirements of law, and except for such steps as
are necessary to disseminate the Offer Documents, Parent will, and will cause
each of its subsidiaries to, hold in confidence the information contained in any
of such labels and lists, use such information only in connection with the Offer
and, if this Agreement is terminated, deliver to the Company all copies of, and
extracts or summaries from, such information then in their possession.

          (d)  Effective upon payment by Parent for all shares of Company Common
Stock accepted for payment pursuant to the Offer, Parent will be entitled to
designate two directors on the Company's Board of Directors, and the Company
will take all action necessary to cause Parent's designees to be elected or
appointed to the Company's Board of Directors, including, without limita-

                                       8

tion, increasing the number of directors or seeking and accepting resignations
of incumbent directors.  Such designees will abstain from any action proposed to
be taken by the Company to amend or terminate this Agreement or waive any action
by Parent, which actions will be effective with the approval of a majority of
the remaining directors.  Parent agrees not to effect any other changes in the
Board of Directors of the Company prior to the Effective Time.

          Section 3.1  Conversion of Capital Stock.  As of the Effective Time,
                       ---------------------------                            
by virtue of the Merger and without any action on the part of the holder of any
shares of capital stock of the Company or the holder of any capital stock of
Sub:

          (a)  Each issued and outstanding share of the capital stock, par value
$.0l per share, of Sub will be converted into and become one fully paid and
nonassessable share of Common Stock, par value $.0l per share, of the Surviving
Corporation.

          (b)  All shares of capital stock of the Company that are owned by the

hereinafter defined) of Parent will be cancelled and retired and will cease to

exchange therefor.  As used in this Agreement, the word "Subsidiary" means, with
respect to any party, any corporation or other organization, whether
incorporated or unincorporated, of which (i) such party or any other

                                      12

          (c)  Subject to Section 3.2(e), each issued and outstanding share of
the $4.75 series Cumulative Convertible Preferred Stock, stated value $50 per
share (the "Company $4.75 Preferred Stock"), of the Company (other than shares
to be cancelled in accordance with Section 3.1(b) and Dissenting Shares (as
defined in Section 3.3)) and each issued and outstanding share of the $3.50
series Cumulative Convertible Preferred Stock, stated value $50 per share (the
"Company $3.50 Preferred Stock" and, together with the Company $4.75 Preferred

                                      13

Stock, the "Company Preferred Stock"), of the Company (other than shares to be
cancelled in accordance with Section 3.1(b) and Dissenting Shares) will be
converted into the right to receive (in accordance with Section 3.2(b)) one
share of preferred stock of Parent which, in the case of the Company $4.75
Preferred Stock, will be designated Parent's $4.75 Series Cumulative Convertible
Preferred Stock (the "Parent $4.75 Preferred Stock") and be convertible
initially into .5588 of a share of Parent Common Stock and otherwise have the
designation, preferences and rights set forth in the Form of Certificate of
Designation, Preferences and Rights of Parent $4.75 Preferred Stock attached
hereto as Exhibit 3.2(c)-1 (the "$4.75 Certificate of Designation") and, in the
case of the Company $3.50 Preferred Stock, will be designated Parent's $3.50
Series Cumulative Convertible Preferred Stock (the "Parent $3.50 Preferred
Stock" and, together with the Parent $4.75 Preferred Stock, collectively the
"Parent New Preferred Stock") and be initially convertible into 1.5625 shares of
Parent Common Stock and otherwise have the designation, preferences and rights
set forth in the Form of Certificate of Designation, Preferences and Rights of
Parent $3.50 Preferred Stock attached hereto as Exhibit 3.2(c)-2 (together with
the $4.75 Certificate of Designation, the "Certificates of Designa-

                                      14

tion").  All shares of Company Preferred Stock, when converted in accordance
with this Section 3.1(c), will no longer be outstanding and will automatically
be cancelled and retired and will cease to exist, and each holder of a
certificate representing any such shares will cease to have any rights with
respect thereto, except the right to receive the shares of Parent Preferred
Stock and any cash or other property to be issued or paid in consideration
therefor upon the surrender of such certificate in accordance with Section 3.2,
without interest, and the right to receive any dividend which such holder is
entitled to be paid pursuant to Section 6.17.

          (d)  Subject to Section 3.2(e), each issued and outstanding share of
Company Common Stock (other than shares to be cancelled in accordance with
Section 3.1(b) and Dissenting Shares) will be converted into the right to
receive (in accordance with Section 3.2(b)) (i) an amount in cash (the "Per
Share Cash Amount"), equal to (x) the excess, if any, of (A) the product of (1)
the Per Share Amount and (2) the excess, if any, of 24,600,000 over the number
of shares of Company Common Stock purchased pursuant to the Offer, over (B) the
aggregate amount paid in the redemption of Company Rights not acquired pursuant
to the Offer, divided by (y) the number of shares of Company Common Stock
outstanding

                                      15

immediately prior to the Effective Time (other than shares to be cancelled in
accordance with Section 3.1(b)) and (ii) (x) if the Per Share Cash Amount is
$0.00, .625 of a share of Common Stock, $1.00 par value per share (the "Parent
Common Stock"), of Parent or (y) if the Per Share Cash Amount exceeds $0.00, the
fraction of a share of Parent Common Stock equal to (A) the product of (1) .625
and (2) the excess of the Per Share Amount over the Per Share Cash Amount,
divided by (B) the Per Share Amount (such fractional amount of a share of Parent
Common Stock under clause (ii)(x) or (ii)(y), as the case may be, the
"Conversion Number"), in each case together with a number of attached Parent
Rights (as defined in Section 5.2)) equal to the Conversion Number divided by 2.
In the event that between the date of this Agreement and the Effective Time the
outstanding shares of Company Common Stock or Parent Common Stock are changed
into a different number of shares or a different class, by reason of any stock
dividend, subdivision, reclassification, recapitalization, split, combination or
exchange of shares, the Conversion Number (and number of attached Parent
Rights), the conversion rates applicable to the shares of Parent New Preferred
Stock issuable in the Merger, and the amount of cash payable in respect of
fractional shares pursuant to Section 3.2(e) will be

                                      16

correspondingly adjusted to reflect such stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange of shares.
All shares of Company Common Stock, when converted in accordance with this
Section 3.1(d), will no longer be outstanding and will automatically be
cancelled and retired and will cease to exist, and each holder of a certificate
representing any such shares will cease to have any rights with respect thereto,
except the right to receive any Per Share Cash Amount, the shares of Parent
Common Stock (and attached Parent Rights) and any cash or other property to be
issued or paid in consideration therefor upon the surrender of such certificate
in accordance with Section 3.2, without interest.

          Section 3.2  Exchange of Certificates and Cash.
                       --------------------------------- 

          (a)  Promptly following the Effective Time, Parent will deposit, or
will cause to be so deposited, with First Chicago Trust Company of New York or
another bank or trust company designated by Parent and reasonably acceptable to
the Company (the "Exchange Agent") for the benefit of the holders of shares of
Company Common Stock and Company Preferred Stock (other than any Dissenting
Shares), any Per Share Cash Amount for such shares and certificates evidencing
the shares of Parent Common Stock and Parent New Preferred Stock pay-

                                      17

able or issuable pursuant to Section 3.1 in exchange for outstanding shares of
Company Common Stock and Company Preferred Stock, as the case may be (such
certificates, together with any cash or other dividends or distributions
declared or made, and any other cash or other property paid or issued through
redemption, merger or otherwise, with respect thereto, being hereinafter
collectively referred to as the "Exchange Fund").  Subject to Section 3.2(g),
the Exchange Agent will deliver any Per Share Cash Amount and the shares of
Parent Common Stock (and attached Parent Rights) and Parent New Preferred Stock
to holders of shares of Company Common Stock and Company Preferred Stock, as the
case may be (other than any Dissenting Shares), in accordance with Section
3.2(b) and the Exchange Fund will not be used for any other purpose.  Except as
contemplated by Section 3.2(c), any interest, dividends or other income earned
on the investment of cash or other property held in the Exchange Fund will be
for the account of Parent.

          (b)  As soon as practicable after the Effective Time, Parent will
cause the Exchange Agent to mail to each holder of record of a certificate or
certificates which immediately prior to the Effective Time represented
outstanding shares of Company Common Stock  or Company Preferred Stock (the
"Certificates") whose

                                      18

shares were converted pursuant to Section 3.1 (i) a letter of transmittal (which
will be in such form and have such provisions as Parent and the Company may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for any Per Share Cash Amount and certificates
representing shares of Parent Common Stock (and attached Parent Rights) or
Parent New Preferred Stock, as the case may be.  Upon surrender of a Certificate
for cancellation to the Exchange Agent or to such other agent or agents as may
be appointed by Parent and Sub, together with such letter of transmittal, duly
executed, the holder of such Certificate will be entitled to receive in exchange
therefor (x) any Per Share Cash Amount payable in respect of such Certificate,
(y) a certificate representing that number of whole shares of Parent Common
Stock (and attached Parent Rights) or Parent New Preferred Stock, as the case
may be, which such holder has the right to receive pursuant to the provisions of
this Article III, and (z) cash in lieu of fractional shares of Parent Common
Stock (and attached Parent Rights) to which such holder is entitled pursuant to
Section 3.2(e) (any Per Share Cash Amount, the shares of Parent Common Stock
(and attached Parent Rights) and cash described in clauses (x), (y) and (z)
above being collectively referred to

                                      19

herein as the "Common Stock Merger Consideration", the shares of Parent New
Preferred Stock described in clause (y) above being collectively referred to
herein as the "Preferred Stock Merger Consideration" and the Common Stock Merger
Consideration and the Preferred Stock Merger Consideration being collectively
referred to herein as the "Merger Consideration") and the Certificate so
surrendered will forthwith be cancelled.  In the event of a transfer of
ownership of Company Common Stock or Company Preferred Stock which is not
registered in the transfer records of the Company, any Per Share Cash Amount and
the certificates representing the proper number of shares of Parent Common Stock
(and attached Parent Rights) or Parent New Preferred Stock may be paid or issued
to a transferee if the Certificate representing such Company Common Stock or
Company Preferred Stock is presented to the Exchange Agent, accompanied by all
documents required to evidence and effect such transfer, together with evidence
that any applicable stock transfer taxes have been paid and the payment of any
required transfer taxes.  Until surrendered as contemplated by this Section 3.2,
each Certificate will be deemed at any time after the Effective Time to
represent only the right to receive upon such surrender the relevant Merger
Consideration.

                                      20

          (c)  No dividends or other distributions declared or made, or any
other cash or other property paid or issued through redemption, merger or
otherwise, after the Effective Time with respect to shares of Parent Common
Stock or Parent New Preferred Stock with a record date after the Effective Time
will be paid to the holder of any unsurrendered Certificate with respect to the
shares of Parent Common Stock or Parent New Preferred Stock which such holder is
entitled to receive upon the surrender thereof in accordance with this Section
3.2.  Subject to the effect of applicable laws, following surrender of any such
Certificate, there will be paid to the record holder of the certificates
representing whole shares of Parent Common Stock or Parent New Preferred Stock
issued in exchange therefor, without interest, (i) the amount of dividends or
other distributions, or other cash or property paid or issued through
redemption, merger or otherwise, with a record date after the Effective Time
theretofore paid or issued with respect to such whole shares of Parent Common
Stock or Parent New Preferred Stock, and (ii) at the appropriate payment date,
the amount of dividends or other distributions, or other cash or property paid
or issued through redemption, merger or otherwise, with a record date after the
Effective Time but prior to such surrender and a payment date

                                      21

subsequent to surrender payable with respect to such whole shares of Parent
Common Stock or Parent New Preferred Stock.

          (d)  The Merger Consideration paid as provided above, together with
any dividends, other distributions or other property paid pursuant to Section
3.2(c), will be deemed to have been issued in full satisfaction of all rights
pertaining to such shares of Company Common Stock or Company Preferred Stock, as
the case may be, and there will be no further registration of transfers on the
stock transfer books of the Surviving Corporation of the shares of Company
Common Stock or Company Preferred Stock which were outstanding immediately prior
to the Effective Time.  If, after the Effective Time, Certificates are presented
to the Surviving Corporation for any reason, they will be cancelled and
exchanged as provided in this Article III.

          (e)  No certificate or scrip representing fractional shares of Parent
Common Stock will be issued upon the surrender for exchange of Certificates, and
such fractional share interests will not entitle the owner thereof to vote or to
any rights of a stockholder of Parent.  In lieu of the issuance of any
fractional shares of Parent Common Stock pursuant to Section 3.1(d), a cash
adjustment will be paid to any holder of Company Common

                                      22

Stock in respect of any such fractional shares that would otherwise be issuable
to such holder in an amount equal to (i) the product of (x) the fraction of a
share of Parent Common Stock to which such holder would otherwise be entitled to
receive pursuant to Section 3.1(d) (after taking into account all shares of

Amount, divided by (ii) .625.

          (f)  Neither Parent nor the Company will be liable to any holder of
shares of Company Common Stock, Company Preferred Stock, Parent Common Stock (or
attached Parent Rights) or Parent New Preferred Stock for any such shares (or
dividends or distributions with respect thereto) or cash delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.

          (g)  Any portion of the Exchange Fund that remains undistributed to
the holders of shares of Company Common Stock and Company Preferred Stock for
one year after the Effective Time will be delivered to Parent, upon demand, and
any holders of shares of Company Common Stock and Company Preferred Stock who
have not theretofore complied with this Article III will thereafter look only to
Parent for the Merger Consideration and any unpaid dividends and distributions
payable pursuant to

                                      23

Section 3.2(c) to which they are entitled pursuant to this Article III.

          (h) Parent or the Exchange Agent will be entitled to deduct and
withhold from the consideration otherwise payable pursuant to this Agreement to

amounts as Parent or the Exchange Agent is required to deduct and withhold with
respect to the making of such payment under the Internal Revenue Code of 1986,
as amended (the "Code"), or any provision of state, local or foreign tax law.
To the extent that amounts are so withheld by Parent or the Exchange Agent, such
withheld amounts will be treated for all purposes of this Agreement as having
been paid to the holder of the shares of Company Common Stock or Company
Preferred Stock in respect of which such deduction and withholding was made by
Parent or the Exchange Agent.

          Section 3.3  Dissenting Shares.  If required by the DGCL but only to

the extent required thereby, shares of Company Common Stock and Company
Preferred Stock which are issued and outstanding immediately prior to the
Effective Time and which are held by holders of such shares of Company Common
Stock and Company Preferred Stock, as the case may be, who have properly
exercised appraisal rights with respect thereto in accordance with

                                      24

Section 262 of the DGCL (the "Dissenting Shares") will not be converted into or
be exchangeable for the right to receive the relevant Merger Consideration, and
holders of such shares of Company Common Stock and Company Preferred Stock will
be entitled to receive payment of the appraised value of such shares of Company
Common Stock and Company Preferred Stock, as the case may be, in accordance with
the provisions of such Section 262 unless and until such holders fail to perfect
or effectively withdraw or lose their rights to appraisal and payment under the
DGCL.  If, after the Effective Time, any such holder fails to perfect or
effectively withdraws or loses such right, such shares of Company Common or
Company Preferred Stock will thereupon be treated as if they had been converted
into and to have become exchangeable for, at the Effective Time, the right to
receive the Merger Consideration and any unpaid dividends and distributions
payable pursuant to Section 3.2(c) to which the holder of such shares of Company
Common Stock or Company Preferred Stock is entitled, without any interest
thereon.  The Company will give Parent prompt notice of any demands received by
the Company for appraisal of shares of Company Common Stock or Company Preferred
Stock and, prior to the Effective Time, Parent will have the right to
participate in all negotiations and proceedings with respect to such de-

                                      25

mands.  Prior to the Effective Time, the Company will not, except with the prior
written consent of Parent, make any payment with respect to, or settle or offer
to settle, any such demands.

                                   ARTICLE IV

defined below) is a corporation or other legal entity duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation or organization and has all requisite corporate power and
authority to own, lease and operate its properties and to carry on its business
as now being conducted, except where the failure to be so organized, existing or
in good standing or to have such power and authority would not, individually or
in the aggregate, have a material adverse effect on the Company and its
Subsidiaries.  As used in this Agreement, any reference to any event, change or
effect being material or having a material adverse effect on or with respect to
an entity (or such entity and its subsidiaries) means such event,

                                      26

operations or financial condition of such entity (or, if with respect to such
entity and its subsidiaries, such group of entities taken as a whole).  The
Company and each Material Company Subsidiary is duly qualified or licensed to do
business and in good standing in each jurisdiction in which the property owned,
leased or operated by it or the nature of the business conducted by it makes
such qualification or licensing necessary, except where the failure to be so
duly qualified or licensed and in good standing would not, individually or in
the aggregate, have a material adverse effect on the Company and its
Subsidiaries.

comparable organizational documents, except for such violations that would not,
individually or in the aggregate, have a material adverse effect on the Company
and its Subsidiaries.

                       ----- 

               (a)  The Company and each of its Subsidiaries has duly filed all
federal, state, local and foreign income Tax Returns (as defined in Section
4.9(b)) required to be filed by it, and all other material Tax Returns required
to be filed by it, and all other material Tax Returns required to be filed by it
except in the case of such other Tax Returns where the failure to so file will
not have a material adverse effect on the

                                      44

Company and its Subsidiaries, and except as set forth in Section 4.9 of the
Company Disclosure Schedule the Company, in all material respects, has duly paid
or caused to be paid all Taxes (as defined in Section 4.9(b)) shown to be due on
such Tax Returns in respect of the periods covered by such returns and has made
adequate provision in the Company's financial statements for payment of all
Taxes anticipated to be payable in respect of all taxable periods or portions
thereof ending on or before the date hereof.  Section 4.9 of the Company
Disclosure Schedule lists the periods through which the Tax Returns required to
be filed by the Company have been examined by the Internal Revenue Service (the
"IRS") or other appropriate taxing authority, or the period during which any
assessments may be made by the IRS or other appropriate taxing authority has
expired.  Except as set forth on Section 4.9 of the Company Disclosure Schedule,
all material deficiencies and assessments asserted as a result of such
examinations or other audits by federal, state, local or foreign taxing
authorities have been paid, fully settled or adequately provided for in the
Company's financial statements, and no issue or claim has been asserted in
writing for Taxes by any taxing authority for any prior period, the adverse
determination of which would result in a deficiency which would have a material
adverse

                                      45

effect on the Company and its Subsidiaries, other than those heretofore paid or
provided for in the Company's Financial statements.  Except as set forth on
Section 4.9 of the Company Disclosure Schedule, there are no outstanding
agreements or waivers extending the statutory period of limitation applicable to
any Tax Return of the Company or its Subsidiaries.  Neither the Company nor any
of its Subsidiaries has filed a consent pursuant to Section 341(f) of the Code
or agreed to have Section 341(f)(2) of the Code apply to any disposition of a
subsection (f) asset (as such term is defined in Section 341(f)(2) of the Code)
owned by the Company or any of its Subsidiaries.  Except as set forth on Section
4.9 of the Company Disclosure Schedule, neither the Company nor any of its
Subsidiaries is a party to any agreement, contract or arrangement that could
result, separately or in the aggregate, in the payment of any "excess parachute
payments" within the meaning of Section 280G of the Code.  Except as set forth
on Section 4.9 of the Company Disclosure Schedule, neither the Company nor any
of its Subsidiaries (i) has been a member of a group filing consolidated returns
for federal income tax purposes, or (ii) is a party to a tax sharing or tax
indemnity agreement or any other agreement of a similar nature that remains in
effect.

                        ----------------------------                           
the opinion of Merrill Lynch & Co., its financial advisor, to the effect that,

Merger, taken as a whole, by the Company's stockholders is fair to the Company's
stockholders from a financial point of view.

          Section 4.11  Company Rights Agreement.  Assuming the accuracy of the

defined in

                                      47

outstanding shares of Company Common Stock.

representation contained in Section 5.10 (without giving effect to the knowledge
qualification thereof), the Board of Directors of the Company has approved the
transaction to be effected in accordance with this Agreement and the Stock
Option Agreement, which will result in Parent becoming an "interested
stockholder" within the meaning of paragraph (a)(1) of Section 203 of the DGCL.

          Section 4.13  Change in Control Provisions.  Other than as set forth
                        ----------------------------                          
on Section 4.13 of the Company Disclosure Schedule, the Board of Directors of
the Company has taken all actions necessary to render inoperative to the Offer,
the Merger and the other transactions contemplated by this Agreement and the
Stock Option Agreement the redemption rights afforded to the holders of the
Company Preferred Stock and the Subsidiary Preferred Stock or to the holders of
or trustees under indentures relating to indebtedness of the Company or any of
its subsidiaries in the event of a "change in control" as defined in the
respective Certificates of Designa-

tions, Preferences and Rights governing the Company Preferred Stock and the
Subsidiary Preferred Stock or in the related indentures or other debt
agreements, as the case may be.

majority of the outstanding shares of Company Common Stock entitled to vote with
respect to the Merger is the only vote of the holders of any class or series of
the Company's capital stock necessary to approve the Merger and the transactions
contemplated hereby or by the Stock Option Agreement.  Assuming the accuracy of
Parent's representations contained in Section 5.10 (without giving effect to the
knowledge qualification thereof), the Board of Directors of the Company has
taken all action necessary to render inoperative to the Offer, the Merger and
the other transactions contemplated by this Agreement and by the Stock Option
Agreement the voting requirements of Article EIGHTH of the Company's Restated
Certificate of Incorporation.

               (a)  Each of Parent and each Material Parent Subsidiary (as
defined below) is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation and has all
requisite corporate power and authority to own, lease and operate its properties
and to carry on its business as now being conducted, except where the failure to
be so organized, existing or in good standing or to have such power and
authority would not, individually or in the aggregate, have a material adverse
effect on Parent and its Subsidiaries taken as a whole. Parent and each Material
Parent Subsidiary is duly qualified or licensed to do business and in good
standing in each jurisdiction in which the property owned, leased or operated by
it or the nature of the business conducted by it makes such qualification or
licensing necessary, except where the failure to be so duly qualified or
licensed and in good standing would not, individually or in the aggregate, have
a material adverse effect on Parent and its Subsidiaries.

               (b)  Each of Northwest Pipeline Corporation, Williams Natural Gas

               (c)  Parent has heretofore made available to the Company a
complete and correct copy of the charter and by-laws or comparable
organizational documents, each as amended to date, of Parent and each Material
Parent Subsidiary. Such charters, by-laws and comparable organizational
documents are in full force and effect. Neither Parent nor any Material Parent
Subsidiary is in violation of any provision of its charter, by-laws or
comparable organizational documents, except for such violations that would not,
individually or in the aggregate, have a material adverse effect on Parent and
its Subsidiaries.

          Section 5.2  Capitalization.  As of the date of this Agreement, the
                       --------------                                        
authorized capital stock of Parent consists of (i) 240,000,000 shares of Parent
Common Stock of which, as of September 30, 1994, 100,904,625 shares were issued
and outstanding (excluding 3,442,189 shares then held by WTG Holdings, Inc., a
wholly-owned subsidiary of Parent), and (ii) 30,000,000 shares of preferred

Parent Common Stock upon exercise of then outstanding options or in respect of
then outstanding deferred stock awards under Parent's employee benefit plans

future purchases or awards under the Parent Plans, and (iii) shares of Parent
capital stock (which could include shares of Parent Common Stock, Parent

otherwise retired any shares of its capital stock, other than 406,112

respective terms thereof and the provisions of this Agreement, duly authorized,

shares of Parent Common Stock and Parent New Preferred Stock that may become
issuable pursuant to the Merger and, following the Merger, upon conversion of
the shares of Parent New Preferred Stock into Parent Common Stock, in each case
in accordance with conversion rates as in effect as of the

of its Subsidiaries is issued or outstanding.  As of the date of this Agreement,

its Subsidiaries to grant, extend or enter into any such option, warrant, call,
subscription or other right, agreement or commitment.  As of the date of this
Agreement, there are no outstanding contractual obligations of Parent or any of

Parent or by a Subsidiary of Parent are free and clear of

                                      54

Stock Option Agreement and to consummate the transactions contemplated hereby

the Merger and by Parent and Sub of the other transactions contemplated hereby
and thereby have been duly authorized by all necessary corporate action on the
part of Parent and Sub and no other corporate proceedings on the part of Parent
or Sub (including stockholder action) are necessary to authorize this Agreement
or the Stock Option Agreement or to consummate the transactions so contemplated,
other than the filing and recordation of the Certificate of Merger and

this Agreement and the Stock Option Agreement has been duly executed and
delivered by each of Parent and Sub and, assuming each of this Agreement and the
Stock Option Agreement, as the case may be, constitutes a valid and binding
obligation of the Company, constitutes a valid and binding obligation of each of
Parent and Sub, enforceable against them in accordance with its terms.

provision of the respective certificates of incorporation or by-laws or
comparable organizational documents of Parent or any Material Parent Subsidiary,

                                      56

(ii) require any filing with, or permit, authorization, consent or approval of,
any Governmental Entity (except where the failure to obtain such permits,
authorizations, consents or approvals or to make such filings would not prevent
consummation of the Merger in any material respect and would not, individually
or in the aggregate, have a material adverse effect on Parent and its
Subsidiaries), (iii) result in a violation or breach of, or constitute (with or
without due notice or lapse of time or both) a default (or give rise to any
right of termination, amendment, cancellation or acceleration) under, or result
in the creation of any lien or other encumbrance on any property or asset of
Parent or any of its Subsidiaries pursuant to, any of the terms, conditions or
provisions of any note, bond, mortgage, indenture, license, lease, contract,
agreement or other instrument or obligation to which Parent or any of its
Subsidiaries is a party or by which any of them or any of their properties or
assets may be bound or (iv) violate any order, writ, injunction, decree,
statute, rule or regulation applicable to Parent or any of its Subsidiaries or
by which any property or asset of Parent or any of its Subsidiaries is bound or
affected, except, in the case of clauses (iii) and (iv), for violations,
breaches, defaults or other occurrences which would not prevent

                                      57

consummation of the Merger in any material respect and would not, individually
or in the aggregate, have a material adverse effect on Parent and its
Subsidiaries.

bound or (ii) any note, bond, mortgage, indenture, lease, license, contract,
agreement or other instrument or obligation to which Parent or any of its
Subsidiaries is a party or by which any of them or any of their properties or
assets may be bound or affected, except in each case for any such defaults or
violations which have not had and are not likely to have a material adverse
effect on Parent and its Subsidiaries.

Parent SEC Documents filed prior to the date of this Agreement, Parent and its
Subsidiaries are in compliance with all applicable statutes, ordinances, rules

release, potential release, leakage, spillage or other actions by Parent or any
of its Subsidiaries or any third party for whom Parent or any of its
Subsidiaries is responsible with respect to hazardous waste, toxic substances,
hazardous substances or other pollutants or contaminants, except for any such
failures to comply or circumstances which have not had since December 31, 1993

except where the adverse consequences resulting from such change of control or
where the failure to obtain such consents or provide such notices would not,
individually or in the aggregate, have a material adverse effect on Parent and
its Subsidiaries; provided, however, that the foregoing exception will not be
applicable to any (i) note, bond, mortgage, indenture, contract, agree-

                                      64

ment or other instrument or obligation relating to indebtedness for borrowed
money of Parent or any of its Subsidiaries with an outstanding principal amount
of less than $5,000,000 or (ii) employment, compensation, termination or
severance agreement, contract or other obligation of Parent or any of its
Subsidiaries.

filed all federal, state, local and foreign income Tax Returns required to be
filed by it, and all other material Tax Returns required to be filed by it,
except in the case of such other Tax Returns where the failure to file will not
have a material adverse effect on Parent and its Subsidiaries, and Parent, in
all material respects, has duly paid or caused to be paid all Taxes shown to be
due on such Tax Returns in respect of the periods covered by such returns and
has made adequate provision in Parent's financial statements for payment of all
Taxes anticipated to be payable in respect of all taxable periods or portions
thereof ending on or before the date hereof.  Section 5.9 of the Disclosure
Schedule delivered by Parent to the Company pursuant to this Agreement (the
"Parent Disclosure Schedule") lists the taxable periods through which the income
Tax Returns required to be filed by Parent have been examined by the IRS or
other appropriate tax authority, or the period

                                      65

during which any assessments may be made by the IRS or other tax authority has
expired.  All material deficiencies and assessments asserted as a result of such
examinations or other audits by federal, state, local or foreign taxing
authorities have been paid, fully settled or adequately provided for in Parent's
financial statements and no issue or claim has been asserted in writing for
Taxes by any taxing authority for any prior period, the adverse determination of
which would result in a deficiency which would have a material adverse effect on
Parent and its Subsidiaries, other than those heretofore paid or provided for in
Parent's financial statements.  Except as set forth on Section 5.9 of the Parent
Disclosure Schedule, there are no outstanding agreements or waivers extending
the statutory period of limitation applicable to any income Tax Return of Parent
or its Subsidiaries.

          Section 6.3   Reasonable Best Efforts.  Subject to the terms and
                        -----------------------

advisable under applicable laws and regulations to consummate and make effective

the Company will use its reasonable best efforts to cause to be delivered to
Parent a letter of Arthur Andersen LLP, dated a date within two business days
before the date on which the S-4 will become effective and addressed to Parent,
in form and substance reasonably satisfactory to Parent and customary in scope
and substance for letters delivered by independent public accountants in
connection with registration statements

                                      77

similar to the S-4, which letter will be brought down to the Effective Time.

          Section 6.5  Letter of Parent's Accountants.  Following receipt by

delivered by independent public accountants in connection with registration

Effective Time.

          Section 6.6  Access to Information.  Upon reasonable notice, the
                       ---------------------                              
Company and Parent will each (and will cause each of their respective
Subsidiaries to) afford to the officers, employees, accountants, counsel and
other representatives of the other, access, during normal business hours during
the period prior to the Effective Time, to all its properties, facilities,
books, contracts, commitments and records and other information as reasonably
requested by such party and, during such period, each of the Company and Parent
will (and will

                                      78

cause each of their respective Subsidiaries to) furnish promptly to the other
(a) a copy of each report, schedule, registration statement and other document
filed or received by it during such period pursuant to the requirements of
United States federal securities laws or regulations, and (b) all other
information concerning its business, properties and personnel as such other
party may reasonably request.  The parties will hold any such information which
is nonpublic in confidence in accordance with the terms of the Confidentiality

meeting of its stockholders for the purpose of voting upon this Agreement
(insofar as it  relates to the Merger), the Merger and related matters and use
its reasonable best efforts to hold such meeting as soon as practicable
following consummation of the Offer.  The Company will, through its Board of
Directors, recommend to its stockholders approval of such matters; provided,
however, that nothing contained in this Section 6.7 will require the Board of
Directors of the Company to

                                      79

take any action or refrain from taking any action which the Board determines in
good faith with advice of counsel could reasonably be expected to result in a
breach of its fiduciary duties under applicable law.  Parent agrees to cause all
shares of Company Common Stock acquired by it pursuant to the Offer or pursuant
to the Stock Option Agreement or both to be represented at such meeting of the
Company's stockholders and to be voted at such meeting in favor of the approval

          Section 6.9  Company Plans.
                       ------------- 

          (a)  On or prior to the Effective Time, the Company and its Board of
Directors (or a committee thereof) will take all action necessary to implement
the provisions contained in Sections 6.9(b) and 6.9(c).

                                      80

          (b)  Except as otherwise agreed with individual option holders, at the
Effective Time, (i) each then outstanding option to purchase shares of Company
Common Stock (a "Company Stock Option") under the Company Plans, whether vested
or unvested, will become fully exercisable and vested, (ii) each Company Stock
Option which is then outstanding will be cancelled and (iii) in consideration of
such cancellation, at the election of the option holder, which may be allocated
to either or both elections, (x) the Company will pay to such holders of Company
Stock Options an amount in respect thereof equal to the product of (A) the
excess, if any, of the Per Share Amount over the respective exercise price
thereof and (B) the number of shares of Company Common Stock subject thereto,
respectively, or (y) Parent will issue an option described in Section 6.9(c) or
6.9(d), as applicable (a "Replacement Option").

          (c)  The Replacement Option with respect to each Company Stock Option,
the exercise price for which exceeds $35 per share, will be an option to
acquire, on the same terms and conditions as were applicable under such Company
Stock Option (except that it will be subject to a vesting period ending on the
first anniversary of the Effective Time), (A) an amount in cash equal to the
product of $10.50 times the number of shares

                                      81

of Company Common Stock purchasable under such Company Stock Option immediately
prior to the Effective Time and (B) the number of shares of Parent Common Stock
equal to the product of .25 and the number of shares of Company Common Stock
purchasable under such Company Stock Option immediately prior to the Effective
Time.  Parent will cause such options to continue to vest and to remain
exercisable following the termination of the option holder's employment with
Parent and its affiliates in accordance with its past practice relative to
Parent's current employees; provided, that with respect to any Current Employee
                            --------                                           
whose employment with Parent or its affiliates is terminated other than
voluntarily by the employee or involuntarily for cause or as a result of
retirement, Parent will cause such options to continue to vest until the earlier
of (i) six months following such termination and (ii) the end of the term of
such Option, as in effect immediately before such termination.  All of the
foregoing payments and issuances of shares in connection with such cancellations
will be made either net of applicable withholding taxes or upon payment of
required withholding taxes by the option holders.

          (d) The Replacement Option with respect to each Company Stock Option,
the exercise price for which is less than or equal to $35 per share, will be an

                                      82

option to acquire, on the same terms and conditions as were applicable under
such Company Stock Option, the same number of shares of Parent Common Stock as
the holder of such Company Stock Option would have been entitled to receive
pursuant to the Merger had such holder exercised such option in full immediately
prior to the Effective Time (not taking into account whether or not such option
was in fact exercisable), at a price per share equal to (A) the aggregate
exercise price for the shares of Company Common Stock deemed otherwise
purchasable pursuant to such Company Stock Option divided by (B) the number of
full shares of Parent Common Stock deemed purchasable pursuant to such Company
Stock Option.  All of the foregoing payments and issuances of shares in
connection with such cancellations will be made either net of applicable
withholding taxes or upon payment of required withholding taxes by the
optionholders.

          (e)  Except as provided herein or as otherwise agreed to by the
parties, and to the extent permitted by the Company Plans, (i) the Company Plans
will terminate as of the Effective Time and the provisions in any other plan,
program or arrangement, providing for the issuance or grant of any other
interest in respect of the capital stock of the Company or any of its
Subsidiaries will be deleted as of the Effective Time and

                                      83

(ii) the Company will use all reasonable efforts to ensure that following the
Effective Time no holder of Company Stock Options or any participant in the
Company Plans or any other plans, programs or arrangements will have any right
thereunder to acquire any equity securities of the Company, the Surviving
Corporation or any Subsidiary thereof.

          (f)  The Company will use reasonable efforts to obtain an agreement
substantially in the form attached to Section 6.9(f) of the Company Disclosure
Schedule on or prior to the date of commencement of the Offer with the employee
identified on such Schedule.

          Section 6.10  Other Employee Benefit Plans.
                        ---------------------------- 

          (a)  Except as otherwise contemplated by this Agreement, the employee
benefit plans (as defined in Section 3(3) of ERISA) and other employee plans,
programs and policies other than salary (collectively, the "Employee Benefit
Plans") of the Company and its Subsidiaries in effect at the date of this
Agreement will, to the extent practicable, remain in effect until otherwise
determined after the Effective Time and, to the extent such Employee Benefit
Plans are not continued, Parent will maintain Employee Benefit Plans with
respect to employees of the Company and its Subsidiaries which are no less
favorable, in the aggregate, than the least favor-

                                      84

able of:  (i) those Employee Benefit Plans covering employees of Parent from
time to time; (ii) those Employee Benefit Plans of the Company and its
Subsidiaries that are in effect on the date of this Agreement other than the
Tran$tock Plan; or (iii) Employee Benefit Plans that are reasonably competitive
with respect to the industry in which the employer of the affected employees
competes; provided, that in any event, until the first anniversary of the
          --------                                                       
Effective Time, the Surviving Corporation will provide individuals who are
employees of the Company and its Subsidiaries as of the Effective Time ("Current
Employees") with Employee Benefit Plans, other than a nonqualified, unfunded
plan maintained primarily to provide deferred compensation benefits to a select
group of "management or highly compensated employees" within the meaning of
Sections 201, 301, and 401 of ERISA, that are no less favorable in the aggregate
than those provided to Current Employees by the Company and for its Subsidiaries
immediately before the Closing Date.  In the case of benefit plans which are
continued and under which the employees' interests are based upon Company Common
Stock, such interests will be based on Parent Common Stock in an equitable
manner.

          (b)  Without limiting the generality of Section 6.10(a), Parent will
cause the Surviving Corpora-

                                      85

tion to (i) honor (A) in accordance with their terms all individual employment,
severance, termination and indemnification agreements which by their express
terms may not be unilaterally amended by the Company or any of its Subsidiaries
and (B) without modification all other employee severance plans, policies,
employment and severance agreements and indemnification arrangements of the
Company or any of its Subsidiaries that are set forth in Section 6.10(b)(i) of
the Company Disclosure Schedule as such plans, policies, or agreements are in
effect on the date of this Agreement through the later of (1) December 31, 1995,
(2) the termination date specified in such document or (3) the date specified in
Section 6.10(b)(i) of the Company Disclosure Schedule, (ii) waive any
limitations regarding pre-existing conditions of Current Employees and their
eligible dependents under any welfare or other employee benefit plans of Parent
and its affiliates in which they participate after the Effective Time (except to
the extent that such limitations would have applied under the analogous plan of
the Company and its subsidiaries immediately before the Effective Time), (iii)
for all purposes under the post-retirement welfare benefit plans and policies of
Parent and its affiliates, treat Current Employees in the same manner as
similarly situated employees of Parent who were hired by Parent

                                      86

before January 1, 1992 in accordance with the terms of such plans and policies
as then in effect, as any such plans and policies are modified by Parent or such
affiliates from time to time, and (iv) for all other purposes under all Employee
Benefit Plans applicable to employees of the Company and its subsidiaries, treat
all service with the Company or any of its subsidiaries by Current Employees
before the Closing as service with Parent and its Subsidiaries, except to the
extent such treatment would result in duplication of benefits or would violate
applicable law.

          (c)  Except as otherwise agreed with individual restricted
stockholders, at the Effective Time, each share of Company Common Stock which
immediately prior to the Effective Time was subject to restrictions on transfer,
whether vested or unvested, will become fully vested and freely transferable and
will be exchanged for unrestricted shares of Parent Common Stock (with attached
Parent Rights) pursuant to Section 3.1(d).

          (d)  Parent will cause the Surviving Corporation or its successor by
merger to continue in full force and effect for a period of not less than six
years from the Effective Time the indemnification provisions contained in
Article Eighth of the Third Restated Certificate of Incorporation attached as
Exhibit 2.4

                                      87

hereto provided that, in the event any claim is asserted or made within such
six-year period, all rights to indemnification in respect of any such claim will
continue until disposition of any and all such claims.  For a period of six
years after the Effective Time, Parent will, or will cause the Company to,
provide directors' and officers' liability insurance having substantially the
same terms and conditions and providing at least the same coverage and amounts
as the directors' and officers' liability insurance maintained by the Company at
the Effective Time for all directors and officers of the Company and its
Subsidiaries, who served as such at or within one year prior to the Effective
Time, provided that Parent will not be required to pay an annual premium for
such insurance in excess of the last annual premium paid prior to the date
hereof (but in such case will purchase as much coverage as possible for such
amount).

          Section 6.11  Exclusivity.
                        ----------- 

          (a)  Except as provided in Section 6.11(b), until the earlier of the
termination of this Agreement pursuant to Section 8.1 or the purchase of shares
of Company Common Stock pursuant to the Offer, the Company will not, nor will it
permit its officers, directors, Subsidiaries, representatives or agents,
directly or indirectly, to, do any of the following: (i)  nego-

                                      88

tiate, undertake, authorize, propose or enter into, either as the proposed
surviving, merged, acquiring or acquired corporation, any transaction (other
than the Offer and the Merger) involving any disposition or other change of
ownership of a substantial portion of the Company's stock or assets (an
"Acquisition Transaction"); (ii) solicit or initiate the submission of a
proposal or offer in respect of, or engage in negotiations concerning, an
Acquisition Transaction; or (iii) furnish or cause to be furnished to any
corporation, partnership, person or other entity or group (other than the other
party and its representatives) (a "Person") any non-public information
concerning the business, operations, properties or assets of the Company in
connection with an Acquisition Transaction; provided, nothing herein will
                                            --------                     
prohibit the Company's Board of Directors from taking and disclosing to the
Company's stockholders a position with respect to a tender offer pursuant to
Rules 14d-9 and 14e-2 promulgated under the Exchange Act.  The Company will
inform Parent by telephone within two business days of its receipt of any
proposal or bid (including the terms thereof and the Person making such proposal
or bid) in respect of any Acquisition Transaction.

          (b)  Notwithstanding anything else contained in this Section 6.11, the
Company and its offi-

                                      89

cers, directors, subsidiaries, representatives and agents may engage in
discussions or negotiations with, and may furnish information to, a third party
who, or representatives of a third party who, makes a written proposal with
respect to an Acquisition Transaction if (i) the Company's Board of Directors
determines in good faith after consultation with its financial advisors that
such proposal may reasonably be expected to result in a transaction that is
financially superior to the transactions contemplated by this Agreement, or (ii)
the Board of Directors of the Company determines in good faith with advice of
outside counsel that failure to do so could reasonably be expected to result in
a breach of its fiduciary duties under applicable law.  If the Company accepts a
proposal for or otherwise engages in any Acquisition Transaction (other than the
Offer or the Merger), it will promptly pay to Parent in reimbursement for
Parent's expenses an amount in cash (not to exceed $15,000,000) equal to the
aggregate amount of Parent's documented out-of-pocket expenses incurred in
connection with pursuing the transactions contemplated by this Agreement as
certified in good faith by Parent and with reasonable detail.

          Section 6.12  Fees and Expenses.  Whether or not the Merger is
                        -----------------                               
consummated, all costs and expenses in-

                                      90

curred in connection with this Agreement and the transactions contemplated
hereby will be paid by the party incurring such expenses.

          Section 6.13  Brokers or Finders.  Each of Parent and the Company
                        ------------------                                 
represents, as to itself, its Subsidiaries and its affiliates, that no agent,
broker, investment banker, financial advisor or other firm or person is or will
be entitled to any brokers' or finder's fee or any other commission or similar
fee in connection with any of the transactions contemplated by this Agreement or
the Stock Option Agreement except Merrill Lynch & Co., whose fees and expenses
will be paid by the Company in accordance with the Company's agreement with such
firm, a copy of which has been provided to Parent, and Smith Barney Inc., whose
fees and expenses will be paid by Parent in accordance with Parent's agreement
with such firm, a copy of which has been provided to the Company, and each of
Parent and the Company will indemnify and hold the other harmless from and
against any and all claims, liabilities or obligations with respect to any other
brokers' or finders' fees, commissions or expenses asserted by any person on the
basis of any act or statement alleged to have been made by such party or its
Subsidiary or affiliate.

                        ------------------------                              
Company Rights effective immediately prior to Parent's acceptance for payment of
shares of Company Common Stock pursuant to the Offer and will not otherwise
redeem the Company Rights, or amend or terminate the Company Rights Agreement,
unless in each such case the Board determines in good faith with the advice of
outside counsel that complying with any such covenant could reasonably be
expected to result in a breach of its fiduciary duties under applicable law. The
Company agrees that the Offer will provide, and require that tendering
stockholders confirm, that Parent will be entitled to receive and retain the
amounts paid in redemption of all Company Rights attached to shares of Company
Common Stock acquired pursuant to the Offer.

          Section 6.15  Rule 145.  The Company will use its reasonable best
                        --------                                           
efforts to cause all persons who, at the time of the meeting of the Company's
stockholders to approve the Merger, may be deemed to be affiliates of the
Company as that term is used in Rule 145 under the Securities Act and who will
become the beneficial owners of Parent Common Stock (and attached Parent Rights)
and Parent New Preferred Stock pursuant to the Merger to execute "affiliates'
letters" in customary form prior to the Effective Time.  Parent and the
Surviving Corporation

                                      92

will use their reasonable efforts to comply with the provisions of Rule 144(c)
under the Securities Act in order that such affiliates may resell such Parent
Common Stock (and attached Parent Rights) and Parent New Preferred Stock
pursuant to Rule 145(d) under the Securities Act.

          Section 6.16  Notification of Certain Matters.   The Company will give
                        -------------------------------                         
prompt notice to Parent, and Parent will give prompt notice to the Company, of
(a) the occurrence, or non-occurrence, of any event the occurrence, or non-
occurrence, of which would be likely to cause (i) any representation or warranty
contained in this Agreement to be untrue or inaccurate in any material respect
or (ii) any covenant, condition or agreement contained in this Agreement not to
be complied with or satisfied in any material respect and (b) any failure of the
Company or Parent, as the case may be, to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it hereunder in any
material respect; provided, however, that the delivery of any notice pursuant to
this Section 6.16 will not limit or otherwise affect the remedies available
hereunder to the party receiving such notice.

          Section 6.17  Interim Company Preferred Stock Dividend.  The Company
                        ----------------------------------------              
will declare a dividend on each

                                      93

share of the Company Preferred Stock to holders of record of such shares as of
the close of the business day next preceding the Effective Time in an amount
equal to the product of (i) a fraction, (x) the numerator of which equals the
number of days between the payment date with respect to the most recent regular
dividend paid by the Company and the Effective Time and (y) the denominator of
which equals 91 and (ii) the amount of the regular quarterly dividend paid by
the Company on the relevant series of Company Preferred Stock.

          Section 6.18  Company Debt Agreements.  The Company will (a) promptly
                        -----------------------                                
seek agreement, on terms reasonably acceptable to Parent, of the banks party to
the Company's revolving credit and letter of credit reimbursement agreements to
(i) amend such agreements to provide that the execution by the Company of this
Agreement and the Stock Option Agreement and the purchase of shares of Company
Common Stock pursuant to the Offer or the Stock Option Agreement do not
constitute an event permitting the banks which are parties thereto to accelerate
the amounts outstanding under such agreements or establish cash collateral
accounts, (ii) amend such agreements to permit the consummation of the Merger,
and (iii) waive the interest rate increase otherwise applicable by reason of
such events, (b) select the latest

                                      94

notice and repurchase dates permitted under the indenture governing the Company
Notes in respect of the "change of control" effected by consummation of the
Offer and (c) in the event that such repurchase date occurs prior to the Merger,
cooperate with Parent in arranging financing on terms reasonably acceptable to
Parent to finance any required repurchase of Company Notes.

subject to the satisfaction, on or prior to the Closing Date, of the following
conditions:

          (a)  Offer.  Parent has accepted for purchase and paid for shares of
Company Common Stock pursuant to the Offer; provided, that this condition will
be deemed satisfied with respect to Parent if Parent will have failed to
purchase shares of Company Common Stock pursuant to the Offer in violation of
the terms of the Offer.

          (b)  Stockholder Approval.  This Agreement (insofar as it relates to
the Merger) and the Merger have been approved and adopted by the affirmative
vote of the

                                      95

holders of Company Common Stock entitled to cast at least a majority of the
total number of votes entitled to be cast by holders of Company Common Stock.

          (c) HSR Approval.  Any waiting period under the HSR Act applicable to
the Merger has expired or been terminated.

          (d)  Registration Statement.  The S-4 has become effective under the

this Agreement.

          (e)  No Injunctions or Restraints.  No temporary restraining order,
preliminary or permanent injunction or other order issued by any court of
competent jurisdiction or other legal restraint or prohibition preventing the
consummation of the Merger is in effect (each party agreeing to use all
reasonable efforts to have any such order reversed or injunction lifted).

          (f)  Listing Matters.  The Parent Common Stock (and the attached
Parent Rights) has been approved for listing on the NYSE, subject to official
notice of issuance.

                                      96

          (g)  No Action.  No action, suit or proceeding by any Governmental
Entity before any court or governmental or regulatory authority is pending
against the Company, Parent or Sub or any of their Subsidiaries challenging the
validity or legality of the transactions contemplated by this Agreement other
than actions, suits or proceedings as to which Parent had actual knowledge at
the time of acceptance for payment of shares of Company Common Stock pursuant to
the Offer or which, in the reasonable opinion of counsel to the party asserting
such condition, do not have a substantial likelihood of resulting in a material
adverse judgment.

          Section 7.2  Conditions of Obligations of Parent and Sub.  The
                       -------------------------------------------      
obligations of Parent and Sub to effect the Merger are further subject to the
Company not  having failed to perform its material obligations required to be
performed by it under Section 6.1 at or prior to the Closing Date, other than
any such failures to perform as to which Parent had actual knowledge at the time
of acceptance for payment of shares of Company Common Stock pursuant to the
Offer.

                       ----------------------------------------

having failed to perform their material obligations required to

                                      97

be performed by them under Section 6.2 at or prior to the Closing Date, other
than any such failures to perform as to which the Company had actual knowledge
at the time of acceptance of payment for shares of Company Common Stock pursuant
to the Offer.

                       -----------                                          
time prior to the Effective Time, whether before or after approval of the
matters presented in connection with the Merger by the stockholders of the
Company:

          (a)  by mutual consent of Parent and the Company by action of their
respective Boards of Directors (with any members of the Board of Directors of
the Company who may hereafter be designated by Parent abstaining);

          (b)  by the Company if (i) Parent fails to commence the Offer as
provided in Section 1.1, (ii) the Offer expires or is terminated without any
shares of Company Common Stock being purchased thereunder, or (iii) Parent fails
to purchase validly tendered shares of Company Common Stock in violation of the
terms and conditions of the Offer or this Agreement;

                                      98

          (c)  by Parent if, due to an occurrence which has made it reasonably
impracticable to satisfy any of the conditions of the Offer set forth in Annex I
hereto at any time prior to the 90th day following the commencement of the
Offer, Parent (i) terminates the Offer or allows the Offer to expire without the
purchase of any shares of Company Common Stock thereunder, unless such
termination or expiration has been caused by or resulted from the failure of
Parent to perform in any material respect any of its covenants and agreements
contained in this Agreement or the Offer, or (ii) fails to pay for shares of
Company Common Stock pursuant to the Offer within 90 days after the date hereof,
unless such failure to pay for such shares is caused by or results from the
failure of Parent to perform in any material respect any of its covenants or
agreements contained in this Agreement or the Offer;

          (d)  by either Parent or the Company if the Merger is not consummated
before June 30, 1995 despite the good faith effort of such party to effect such
consummation (unless solely by reason of the conditions provided for in Section
7.1(e), and 7.1(g) (in which case such date will be September 30, 1995) or the
failure to so consummate the Merger by such date is due to the action or failure
to act of the party seeking to termi-

                                      99

nate this Agreement, which action or failure to act constitutes a breach of this
Agreement);

          (e)  by either Parent or the Company if any court of competent
jurisdiction has issued an injunction permanently restraining, enjoining or
otherwise prohibiting the consummation of the Offer or the Merger, which
injunction has become final and non-appealable;

          (f)  prior to the expiration of the Offer, by Parent if the Company
rescinds its redemption of the Company Rights and all other conditions to
consummation of the Offer are satisfied, or the Board of Directors of the
Company withdraws, amends or modifies in a manner adverse to Parent its
favorable recommendation of the Offer or the Merger or promulgates any
recommendation with respect to an Acquisition Transaction (including a
determination to take no position) other than a recommendation to reject such
Acquisition Transaction; or

          (g)  prior to the expiration of the Offer, by the Company if (i) (A)
any of the representations and warranties of Parent contained in this Agreement
were incorrect in any material respect when made or have since become, and at
the time of termination remain, incorrect in any material respect, or (B) there
has been a material breach on the part of Parent in the covenants of Parent set
forth herein, or any failure on the part of Parent to

                                      100

comply with its material obligations hereunder, or any other events or
circumstances have occurred, such that, in any such case, Parent could not
satisfy on or prior to June 30, 1995, any of the conditions to the Closing set
forth in Sections 7.1 or 7.3, or (ii) the Company receives a written offer with
respect to an Acquisition Transaction and the Board of Directors of the Company,
after consulting with its outside counsel and financial advisor, determines in
good faith that such Acquisition Transaction is more favorable to the Company's
stockholders than the transactions contemplated by this Agreement and, not later
than the time of such termination, the Company has paid the expense
reimbursement required by Section 6.11(b).

          Section 8.2  Effect of Termination.  In the event of a termination of

obligation on the part of Parent, Sub or the Company or their respective
officers or directors, other than (a)(i) the provisions of the last sentence of
Section 6.11(b), which will survive for a period of one year from the date of
any such termination if and only if (A) Parent has not received the payment
pursuant to Section 6.11(b) and (B) such termination of this Agreement is

                                      101

pursuant to Section 8.1(b)(ii) by reason of the Minimum Condition having failed
to be satisfied, Section 8.1(c) by reason of the failure to satisfy the
conditions set forth in paragraph (e) or (f) of Annex I hereto, Section 8.1(f)
or Section 8.1(g)(ii), (ii) Sections 6.12 and 6.13, and (iii) the last sentence
of Section 6.6, and (b) to the extent that such termination results from the
willful breach by a party hereto of any of its covenants or agreements set forth
in this Agreement.

     exercised or done by the Corporation, subject, nevertheless, to the
     provisions of the GCL, this Restated Certificate of Incorporation, and any

in effect:

          (1)  Subject to Section 3 of this Article EIGHTH, the Corporation
     shall indemnify any person who was or is a party or is threatened to be
     made a party to any threatened, pending or completed action, suit or
     proceeding, whether civil, criminal, administrative or investigative (other
     than an action by or in the right of the Corporation) by reason of the fact
     that such person is or was a Director, officer, employee or agent of the
     Corporation, or is or was serving at the request of the Corporation as a
     director, officer, employee or agent of another corporation, partnership,
     joint

                                       3

     venture, trust or other enterprise, against expenses (including attorneys'
     fees), judgments, fines and amounts paid in settlement actually and
     reasonably incurred in connection with such action, suit or proceeding if
     such person acted in good faith and in a manner such person reasonably
     believed to be in or not opposed to the best interests of the Corporation,
     and, with respect to any criminal action or proceeding, had no reasonable
     cause to believe the conduct was unlawful.  The termination of any action,
     suit or proceeding by judgment, order, settlement, conviction or upon a
     plea of nolo contendere or its equivalent, shall not, of itself, create a
     presumption that the person did not act in good faith and in a manner which
     such person reasonably believed to be in or not opposed to the best
     interests of the Corporation, and, with respect to any criminal action or
     proceeding, had reasonable cause to believe that the conduct was unlawful.

          (2)  Subject to Section 3 of this Article EIGHTH, the Corporation
     shall indemnify any person who was or is a party or is threatened to be
     made a party to any threatened, pending or completed action or suit by or
     in the right of the Corporation to procure a judgment in its favor by
     reason of the fact that such person is or was a Director, officer, employee
     or agent of the Corporation, or is or was serving at the request of the
     Corporation as a director, officer, employee or agent of another
     corporation, partnership, joint venture, trust or other enterprise against
     expenses (including attorneys' fees) actually and reasonably incurred in
     connection with the defense or settlement of such action or suit if such
     person acted in good faith and in a manner such person reasonably believed
     to be in or not opposed to the best interests of the Corporation; except
     that no indemnification shall be made in respect to any claim, issue or
     matter as to which such person shall have been adjudged to be liable to the
     Corporation unless and only to the extent that the Court of Chancery of the
     State of Delaware or the court in which such action or suit was brought
     shall determine upon application that, despite the adjudication of
     liability but in view of all the circumstances of the case, such person is
     fairly and reasonably entitled to indemnity for such

                                       4

     expenses which the Court of Chancery of the State of Delaware or such other
     court shall deem proper.

          (3)  Any indemnification under this Article EIGHTH (unless ordered by
     a court) shall be made by the Corporation only as authorized in the
     specific case upon a determination that indemnification of the Director,
     officer, employee or agent is proper in the circumstances because such
     person has met the applicable standard of conduct set forth in Section 1 or
     Section 2 of this Article EIGHTH, as the case may be.  Such determination
     shall be made (i) by the Board of Directors by a majority vote of a quorum
     consisting of Directors who were not parties to such action, suit or
     proceeding, or (ii) if such a quorum is not obtainable, or, even if
     obtainable a quorum of disinterested Directors so directs, by independent
     legal counsel in a written opinion, or (iii) by the stockholders.  To the
     extent, however, that a Director, officer, employee or agent of the
     Corporation has been successful on the merits or otherwise in defense of
     any action, suit or proceeding described above, or in defense of any claim,
     issue or matter therein, such person shall be indemnified against expenses
     (including attorneys' fees) actually and reasonably incurred in connection
     therewith, without the necessity of authorization in the specific case.

          (4)  For purposes of any determination under Section 3 of this Article
     EIGHTH, a person shall be deemed to have acted in good faith and in a
     manner such person reasonably believed to be in or not opposed to the best
     interests of the Corporation, or, with respect to any criminal action or
     proceeding, to have had no reasonable cause to believe such person's
     conduct was unlawful, if such person's action is based on the records or
     books of account of the Corporation or another enterprise, or on
     information supplied to such person by the officers of the Corporation or
     another enterprise in the course of their duties, or on the advice of legal
     counsel for the Corporation or another enterprise or on information or
     records given or reports made to the Corporation or another enterprise by
     an independent certified public accountant by an appraiser or other expert
     selected with reasonable care by the

                                       5

     Corporation or another enterprise.  The term "another enterprise" as used
     in this Section 4 shall mean any other corporation or any partnership,
     joint venture, trust or other enterprise of which such person is or was
     serving at the request of the Corporation as a director, officer, employee
     or agent.  The provisions of this Section 4 shall not be deemed to be
     exclusive or to limit in any way the circumstances in which a person may be
     deemed to have met the applicable standard of conduct set forth in Section
     1 or 2 of this Article EIGHTH, as the case may be.

          (5)  Notwithstanding any contrary determination in the specific case
     under Section 3 of this Article EIGHTH, and notwithstanding the absence of
     any determination thereunder, any Director, officer, employee or agent may
     apply to any court of competent jurisdiction in the State of Delaware for
     indemnification to the extent otherwise permissible under Sections 1 and 2
     of this Article EIGHTH.  The basis of such indemnification by a court shall
     be a determination by such court that indemnification of the Director,
     officer, employee or agent is proper in the circumstances because such
     person has met the applicable standards of conduct set forth in Sections 1
     and 2 of this Article EIGHTH, as the case may be.  Notice of any
     application for indemnification pursuant to this Section 5 shall be given
     to the Corporation promptly upon the filing of such application.

          (6)  Expenses by an officer or Director incurred in defending a civil
     or criminal action, suit or proceeding may be paid by the Corporation in
     advance of the final disposition of such action, suit or proceeding upon
     receipt of an undertaking by or on behalf of the Director or officer to
     repay such amount if it shall ultimately be determined that such person is
     not entitled to be indemnified by the Corporation as authorized in this
     Article EIGHTH.

          Such expenses incurred by other employees and agents shall be so paid
     upon such terms and conditions, if any, as the Board of Directors deems
     appropriate.

                                       6

          (7)  The indemnification and advancement of expenses provided by or
     granted pursuant to this Article EIGHTH shall not be deemed exclusive of
     any other rights to which those seeking indemnification or advancement of
     expenses may be entitled under any By-law, agreement, contract, vote of
     stockholders or disinterested Directors or otherwise, both as to action in
     such person's official capacity and as to action in another capacity while
     holding such office, it being the policy of the Corporation that
     indemnification of the persons specified in Sections 1 and 2 of this
     Article EIGHTH shall be made to the fullest extent permitted by law. The
     provisions of this Article EIGHTH shall not be deemed to preclude the
     indemnification of any person who is not specified in Sections 1 or 2 of
     this Article EIGHTH but whom the Corporation has the power or obligation to
     indemnify under the provisions of the General Corporation Law of the State
     of Delaware or otherwise.

          (8)  The Corporation may purchase and maintain insurance on behalf of
     any person who is or was a Director, officer, employee or agent of the
     Corporation, or is or was serving at the request of the Corporation as a
     director, officer, employee or agent of another corporation, partnership,
     joint venture, trust or other enterprise against any liability asserted
     against such person and incurred by such person in any such capacity, or
     arising out of such person's status as such, whether or not the Corporation
     would have the power or the obligation to indemnify such person against
     such liability under the provisions of this Article EIGHTH.

          (9)   A.  For purposes of this Article EIGHTH, reference to "the
     Corporation" shall include, in addition to the resulting corporation, any
     constituent corporation (including any constituent of a constituent)
     absorbed in a consolidation or merger which, if its separate existence had
     continued, would have had power and authority to indemnify its directors,
     officers, employees or agents so that any person who is or was a director,
     officer, employee or agent of such constituent corporation, or is or was
     serving at the request of such constituent corporation as a director,
     officer, employee or agent of another corporation, partnership, joint

                                       7

     venture, trust or other enterprise, shall stand in the same position under
     the provisions of this Article EIGHTH with respect to the resulting or
     surviving corporation as such person would have with respect to such
     constituent corporation if its separate existence had continued.

               B.  For purposes of this Article EIGHTH, references to "other
     enterprises" shall include employee benefit plans; references to "fines"
     shall include any excise taxes assessed on a person with respect to an
     employee benefit plan; and references to "serving at the request of the
     Corporation" shall include any service as a Director, officer, employee or
     agent of the Corporation which imposes duties on, or involves services by,
     such Director, officer, employee or agent with respect to an employee
     benefit plan, its participants or beneficiaries; and a person who acted in
     good faith and in a manner such person reasonably believed to be in the
     interests of the participants and beneficiaries of an employee benefit plan
     shall be deemed to have acted in a manner "not opposed to the best
     interests of the Corporation" as referred to in this Article EIGHTH.

          (10)  The indemnification and advancement of expenses provided by, or
     granted pursuant to, this Article EIGHTH shall, unless otherwise provided
     when authorized or ratified, continue as to a person who has ceased to be a
     Director, officer, employee or agent and shall inure to the benefit of the
     heirs, executors and administrators of such a person.

                         Pursuant to Section 151 of the

                General Corporation Law of the State of Delaware

                          ____________________________

          The undersigned DOES HEREBY CERTIFY that the following resolution was
duly adopted on _________ __, 1995, by the Board of Directors (the "Board") of
The Williams Companies, Inc., a Delaware corporation (hereinafter called the
"Corporation"), in accordance with the provisions of Section 151 of the General
Corporation Law of the State of Delaware:

               RESOLVED that pursuant to authority expressly granted to and
     vested in the Board by provisions of the Restated Certificate of
     Incorporation of the Corporation (the "Certificate of Incorporation"), the
     issuance of a series of Preferred Stock, par value $1 per share (the
     "Preferred Stock"), which shall consist of up to 2,990,000 of the _________
     shares of Preferred Stock which the Corporation now has authority to issue,
     be, and the same hereby is, authorized, and the powers, designations,
     preferences and relative, participating, optional or other special

     rights, and the qualifications, limitations or restrictions  thereof, of
     the shares of such series (in addition to the powers, designations,
     preferences and relative, participating, optional or other special rights,
     and the qualifications, limitations or restrictions thereof, set forth in
     the Certificate of Incorporation which may be applicable to the Preferred
     Stock) are fixed as follows:

          (i)  The designation of such series of the Preferred Stock authorized
by this resolution shall be the $4.75 Cumulative Convertible Preferred Stock
(the "$4.75 Preferred Stock").  The total number of shares of the $4.75
Preferred Stock shall be 2,990,000.

          (ii)  Holders of shares of $4.75 Preferred Stock will be entitled to
receive, when and as declared by the Board out of assets of the Corporation
legally available for payment, an annual cash dividend of $4.75 per share,
payable in quarterly installments on February 1, May 1, August 1 and November 1,
commencing [the first such date following the Effective Time] (each a "dividend
payment date").  Dividends on the $4.75 Preferred Stock will be cumulative from
the date of initial issuance of shares of $4.75 Preferred Stock.  Dividends will
be payable to holders of record as they appear on the stock books of the
Corporation on such record dates, not more than 60 days nor less than 10 days
preceding the payment dates thereof, as shall be fixed by the Board.  When
dividends are not paid in full upon the $4.75 Preferred Stock and any other
Parity Preferred Stock (as defined in paragraph (ix)), all dividends declared
upon shares of Parity Preferred Stock will be declared pro rata so that in all
cases the amount of dividends declared per share on the $4.75 Preferred Stock
and such other Parity Preferred Stock shall bear to each other the same ratio
that accumulated and unpaid dividends per share on the shares of $4.75 Preferred
Stock and such other Parity Preferred Stock bear to each other.  Except as set
forth in the preceding sentence, unless full cumulative dividends on the $4.75
Preferred Stock have been paid, no dividends (other than in Common Stock of the
Corporation) may be paid or declared and set aside for payment or other
distribution made upon the Common Stock or on any other stock of the Corporation
ranking junior to or on a

                                       2

parity with the $4.75 Preferred Stock as to dividends, nor may any Common Stock
or any other stock of the Corporation ranking junior to or on a parity with the
$4.75 Preferred Stock as to dividends be redeemed, purchased or otherwise
acquired for any consideration  (or any payment made to or available for a
sinking fund for the redemption of any shares of such stock; provided, however,
                                                             --------  ------- 
that any moneys theretofore deposited in any sinking fund with respect to any
Preferred Stock of the Corporation in compliance with the provisions of such
sinking fund may thereafter be applied to the purchase or redemption of such
Preferred Stock in accordance with the terms of such sinking fund regardless of
whether at the time of such application full cumulative dividends upon shares of
the $4.75 Preferred Stock outstanding to the last dividend payment date shall
have been paid or declared and set apart for payment) by the Corporation (except
by conversion into or exchange for stock of the Corporation ranking junior to
the $4.75 Preferred Stock as to dividends).   Dividends payable on the $4.75
Preferred Stock for any period less than the full dividend period will be
computed on the basis of a 360-day year consisting of twelve 30-day months.

          (iii)  The shares of $4.75 Preferred Stock shall rank prior to the
shares of Common Stock and of any other class of stock of the Corporation
ranking junior to the $4.75 Preferred Stock upon liquidation, so that in the
event of any liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary, the holders of the $4.75 Preferred Stock shall be
entitled to receive out of the assets of the Corporation available for
distribution to its stockholders, whether from capital, surplus or earnings,
before any distribution is made to holders of shares of Common Stock or any
other such junior stock, (A) in the case of an involuntary liquidation,
dissolution or winding up, an amount equal to $50 per share or (B) in the case
of a voluntary liquidation, dissolution or winding up, the then applicable
Redemption Price (as defined in paragraph (iv) below) (as the case may be, the
"Liquidation Preference" of a share of $4.75 Preferred Stock), in each case plus
an amount equal to all dividends (whether or not earned or declared) accumulated
and unpaid on the shares of $4.75 Preferred Stock to the date of final
distribution.  After payment of the full amount of the Liquidation Preference
and such dividends, the holders of shares of

                                       3

$4.75 Preferred Stock will not be entitled to any further participation in any
distribution of assets by the Corporation.  If, upon any liquidation,
dissolution or winding up of the Corporation, the assets of the Corporation, or
proceeds thereof, distributable among the holders of shares of Parity Preferred
Stock shall be insufficient to pay in full the preferential amount aforesaid,
then such assets, or the proceeds thereof, shall be distributable among such
holders ratably in accordance with the respective amounts which would be payable
on such shares if all amounts payable thereon were payable in full.  For the
purposes hereof, neither a consolidation or merger of the Corporation with or
into any other corporation, nor a merger of any other corporation with or into
the Corporation, nor a sale or transfer of all or any part of the Corporation's
assets for cash or securities shall be considered a liquidation, dissolution or
winding up of the Corporation.

          (iv)  The $4.75 Preferred Stock will be redeemable, in whole at any
time or from time to time in part at the option of the Corporation, upon not
less than 30 nor more than 60 days' notice, at the following redemption prices
(the "Redemption Prices") per share if redeemed during the twelve-month period
ending November 1 of the year indicated below; plus, in each case, all dividends
accrued and unpaid on the $4.75 Preferred Stock up to the date fixed for
redemption:
 
                                                   Redemption
                                                      Price
     Year                                           Per Share
     ----                                           ---------

1995                                                 $ 50.475
After 1995                                             50.000

          In the event that the Corporation determines to redeem fewer than 
all of the outstanding shares of the $4.75 Preferred Stock, the shares to be 
redeemed shall be determined by lot or a substantially equivalent method.

          If a notice of redemption has been given pursuant to this paragraph
(iv) and if, on or before the date fixed for redemption, the funds necessary for
such redemption shall have been set aside by the Corporation, separate and apart
from its other funds, in trust for the pro rata benefit of the holders of the
shares so called

                                       4

for redemption, then, notwithstanding that any certificates for such shares have
not been surrendered for cancellation, on the redemption date dividends shall
cease to accrue on the shares of $4.75 Preferred Stock to be redeemed, and at
the close of business on the redemption date the holders of such shares shall
cease to be stockholders with respect to such shares and shall have no interest
in or claims against the Corporation by virtue thereof and shall have no voting
or other rights with respect to such shares, except the right to receive the
moneys payable upon such redemption, without interest thereon, upon surrender
(and endorsement, if required by the Corporation) of their certificates, and the
shares evidenced thereby shall no longer be outstanding.  Subject to applicable
escheat laws, any moneys so set aside by the Corporation and unclaimed at the
end of two years from the redemption date shall revert to the general funds of
the Corporation, after which reversion the holders of such shares so called for
redemption shall look only to the general funds of the Corporation for the
payment of the amounts payable upon such redemption.  Any interest accrued on
funds so deposited shall be paid to the Corporation from time to time.

          (v)  The holders of shares of $4.75 Preferred Stock shall have no
voting rights whatsoever, except for any voting rights to which they may be
entitled under the laws of the State of Delaware, and except as follows:

               (I)  If and whenever at any time or times dividends payable on
          the $4.75 Preferred Stock or on any other Preferred Stock shall have
          been in arrears and unpaid in an aggregate amount equal to or
          exceeding the amount of dividends payable thereon for six quarterly
          periods, then the holders of the Preferred Stock shall have, in
          addition to the other voting rights set forth herein, the exclusive
          right, voting separately as a class, to elect two directors of the
          Corporation, such directors to be in addition to the number of
          directors constituting the Board immediately prior to the accrual of
          such right, the remaining directors to be elected by the other class
          or classes of stock entitled to vote therefor at each meeting of
          stockholders held for the purpose of electing directors.  Such voting
          right shall

                                       5

          continue until such time as all cumulative dividends accumulated on
          all the Preferred Stock having cumulative dividends shall have been
          paid in full and until any noncumulative dividends payable on all the
          Preferred Stock having noncumulative dividends shall have been paid
          regularly for at least one year, at which time such voting right of
          the holders of the Preferred Stock shall terminate, subject to
          revesting at such time as there shall occur each and every subsequent
          event of default of the character indicated above.

               Whenever such voting right shall have vested, such right may be
          exercised initially either at a special meeting of the holders of the
          Preferred Stock, called as hereinafter provided, or at any annual
          meeting of stockholders held for the purpose of electing directors,
          and thereafter at each successive annual meeting.

               At such time when such voting right shall have vested in the
          holders of the Preferred Stock, and if such right shall not already
          have been initially exercised, a proper officer of the Corporation
          shall, upon the written request of the holders of record of 10 percent
          in number of shares of the Preferred Stock then outstanding, addressed
          to the Secretary of the Corporation, call a special meeting of the
          holders of the Preferred Stock and of any other class or classes of
          stock having voting power with respect thereto for the purpose of
          electing directors.  Such meeting shall be held at the earliest
          practicable date upon the notice required for annual meetings of
          stockholders at the place for holding of annual meetings of
          stockholders of the Corporation, or, if none, at a place designated by
          the Secretary of the Corporation.  If such meeting shall not be called
          by the proper officers of the Corporation within 30 days after the
          personal service of such written request upon the Secretary of the
          Corporation, or within 30 days after mailing the same within the
          United States of America, by registered mail,

                                       6

          addressed to the Secretary of the Corporation at its principal office
          (such mailing to be evidenced by the registry receipt issued by the
          postal authorities), then the holders of record of 10 percent in
          number of shares of the Preferred Stock then outstanding may designate
          in writing one of their number to call such meeting at the expense of
          the Corporation, and such meeting may be called by such person so
          designated upon the notice required for annual meetings of
          stockholders and shall be held at the same place as is elsewhere
          provided for in this subparagraph (I).  Any holder of the Preferred
          Stock shall have access to the stock books of the Corporation for the
          purpose of causing a meeting of stockholders to be called pursuant to
          the provisions of this paragraph.  Notwithstanding the provisions of
          this paragraph, however, no such special meeting shall be called
          during a period within 90 days immediately preceding the date fixed
          for the next annual meeting of stockholders.

               At any meeting held for the purpose of electing directors at
          which the holders of the Preferred Stock shall have the right to elect
          directors as provided herein, the presence in person or by proxy of
          the holders of 33-1/3 percent of the then outstanding shares of the
          Preferred Stock shall be required and be sufficient to constitute a
          quorum of the Preferred Stock for the election of directors by the
          Preferred Stock.  At any such meeting or adjournment thereof (A) the
          absence of a quorum of the holders of the Preferred Stock shall not
          prevent the election of directors other than those to be elected by
          the holders of the Preferred Stock and the absence of a quorum or
          quorums of the holders of other classes of capital stock entitled to
          elect such other directors shall not prevent the election of directors
          to be elected by the holders of the Preferred Stock and (B) in the
          absence of a quorum of the holders of any class of stock entitled to
          vote for the election of directors, a majority of the holders present
          in person or by proxy of such class shall have the power to

                                       7

          adjourn the meeting for the election of directors which the holders of
          such class are entitled to elect, from time to time, without notice
          other than announcement at the meeting, until a quorum shall be
          present.

               The directors elected pursuant to this subparagraph (I) shall
          serve until the next annual meeting or until their respective
          successors shall be elected and shall qualify; provided, however, that
                                                         --------  -------      
          when the right of the holders of the Preferred Stock to elect
          directors as herein provided shall terminate, the terms of office of
          all persons so elected by the holders of the Preferred Stock shall
          terminate, and the number of directors of the Corporation shall
          thereupon be such number as may be provided in the By-laws of the
          Corporation irrespective of any increase made pursuant to this
          subparagraph (I).

               So long as any shares of $4.75 Preferred Stock are outstanding,
          the By-laws of the Corporation shall contain provisions ensuring that
          the number of directors of the Corporation shall at all times be such
          that the exercise, by the holders of shares of $4.75 Preferred Stock
          and the holders of other Preferred Stock, of the right to elect
          directors under the circumstances provided in this subparagraph (I)
          will not contravene any provisions of the Corporation's Certificate of
          Incorporation or By-laws.

               (II)  So long as any shares of the $4.75 Preferred Stock remain
          outstanding, the Corporation will not, either directly or indirectly
          or through merger or consolidation with any other corporation, without
          the affirmative vote at a meeting or the written consent with or
          without a meeting of the holders of at least 66-2/3 percent in number
          of shares of the $4.75 Preferred Stock then outstanding, (A) create
          any class or classes of stock ranking prior to or on a parity with the
          $4.75 Preferred Stock either as to dividends or upon liquidation or
          increase the authorized

                                       8

          number of shares of any class or classes of stock ranking prior to or
          on a parity with the $4.75 Preferred Stock either as to dividends or
          upon liquidation, or create or authorize any obligation or security
          convertible into shares of stock of any class ranking prior to or on a
          parity with the Preferred Stock either as to dividends or upon
          liquidation, but may, without such consent, create or authorize
          obligations or securities convertible into shares of Preferred Stock
          or (B) amend, alter or repeal any of the provisions of the Certificate
          of Incorporation (including this resolution) so as to affect adversely
          the preferences, special rights or powers of the $4.75 Preferred Stock
          or of the holders thereof.

          (vi)  Except as provided in paragraph (v)(II), no consent of the
holders of the $4.75 Preferred Stock shall be required for (a) the creation of
any indebtedness of any kind of the Corporation, (b) the creation, or increase
or decrease in the amount, of any class or series of stock of the Corporation
not ranking prior to or on a parity with the $4.75 Preferred Stock or (c) any
increase or decrease in the amount of authorized Common Stock or any increase,
decrease or change in the par value thereof or in any other terms thereof.

          (vii)  Subject to the provisions of paragraph (iv) hereof, the Board
reserves the right by subsequent amendment of this resolution from time to time
to increase or decrease the number of shares which constitute the $4.75
Preferred Stock (but not below the number of shares thereof then outstanding)
and in other respects to amend this resolution within the limitations provided
by law, this resolution and the Certificate of Incorporation.

          (viii)  At the option of the holder thereof and upon surrender thereof
for conversion to the Corporation at the office of the Transfer Agent of the
Corporation's Common Stock in the Borough of Manhattan, the City of New York or
in the City of Tulsa, each share of $4.75 Preferred Stock will be convertible
(or if such share is called or surrendered for redemption, then in respect of
such share to and including, but not after, the redemption date) into fully paid
and nonassessable shares

                                       9

of Common Stock at the initial conversion rate of .5588 of a share of Common
Stock for each share of $4.75 Preferred Stock, the conversion rate being subject
to adjustment as hereinafter provided:

               (I)  In case the Corporation shall (A) pay a dividend in shares
          of its capital stock, (B) subdivide its outstanding shares of Common
          Stock into a greater number of shares, (C) combine its outstanding
          shares of Common Stock into a smaller number of shares, or (D) issue
          by reclassification of its shares of Common Stock any shares of its
          capital stock, the conversion rate in effect immediately prior thereto
          shall be adjusted so that the holder of a share of $4.75 Preferred
          Stock surrendered for conversion after the record date fixing
          stockholders to be affected by such event shall be entitled to receive
          upon conversion the number of such shares of Common Stock which he
          would have been entitled to receive after the happening of such event
          had such share of $4.75 Preferred Stock been converted immediately
          prior to such record date.  Such adjustment shall be made whenever any
          of such events shall happen, but shall also be effective retroactively
          as to shares of $4.75 Preferred Stock converted between such record
          date and the date of the happening of any such event.

               (II)  In case the Corporation shall issue rights or warrants to
          all holders of its Common Stock entitling them to subscribe for or
          purchase shares of Common Stock at a price per share less than the
          Current Market Price Per Share (as defined in subparagraph (IV) below)
          of Common Stock at the record date mentioned below, the number of
          shares of Common Stock into which each share of $4.75 Preferred Stock
          shall thereafter be convertible shall be determined by multiplying the
          number of shares of Common Stock into which such   share of $4.75
          Preferred Stock was theretofore convertible by a fraction, the
          numerator of which shall be the number of shares of Common Stock
          outstanding on the date of issuance of such rights or warrants plus
          the number of

                                      10

          additional shares of Common Stock offered for subscription or
          purchase, and the denominator of which shall be the number of the
          shares of Common Stock outstanding on the date of issuance of such
          rights or warrants plus the number of shares which the aggregate
          offering price of the total number of shares so offered would purchase
          at such Current Market Price Per Share.  Such adjustment shall be made
          whenever such rights or warrants are issued, but shall also be
          effected retroactively as to shares of $4.75 Preferred Stock converted
          between the record date for the determination of stockholders entitled
          to receive such rights or warrants and the date such rights or
          warrants are issued.

               (III) In case the Corporation shall distribute to all holders of
          its Common Stock evidences of its indebtedness or assets (excluding
          any cash dividend or distribution made out of current or retained
          earnings) or rights to subscribe other than as set forth in
          subparagraph (II) above, then in each such case the number of shares
          of Common Stock into which each share of $4.75 Preferred Stock shall
          thereafter be convertible shall be determined by multiplying the
          number of shares of Common Stock into which such share was theretofore
          convertible by a fraction, the numerator of which shall be the Current
          Market Price Per Share of the Common Stock on the record date fixed by
          the Board for such distribution, and the denominator of which shall be
          such Current Market Price Per Share of the Common Stock less the then
          fair market value (as determined by the Board, whose determination
          shall be conclusive) of the portion of the assets, evidences of
          indebtedness or subscription rights so distributed applicable to one
          share of the Common Stock.  Such adjustment shall be made whenever any
          such distribution is made, but shall also be effective retroactively
          as to shares of $4.75 Preferred Stock converted between the record
          date for the determination of stockholders entitled to receive such

                                      11

          distribution and the date such distribution is made.

               (IV)  For the purpose of any computation under subparagraphs (II)
          and (III) above and (VI) below, the "Current Market Price Per Share"
          of Common Stock at any date shall be deemed to be the average of the
          daily closing prices for the 15 consecutive trading days commencing 20
          trading days before the day in question.  The closing price for each
          day shall be reported on the New York Stock Exchange-Composite
          Transactions Tape or as reported by any successor central market
          system.

               (V)  No adjustment in the conversion rate shall be required
          unless such adjustment would require an increase or decrease of at
          least 1% in such rate; provided, however, that any adjustments which
          by reason of this subparagraph (V) are not required to be made shall
          be carried forward and taken into account in any subsequent
          adjustment.  All calculations under this paragraph (viii) shall be
          made to the nearest one-hundredth of a share.

               (VI) No fractional shares or scrip representing fractional shares
          of Common Stock shall be issued upon the conversion of any share of
          $4.75 Preferred Stock.  If the conversion thereof results in a
          fraction, an amount equal to such fraction multiplied by the Current
          Market Price Per Share of Common Stock (as defined in subparagraph
          (IV) above) as of the conversion date shall be paid to such holder in
          cash by the Corporation.

               (VII)  In case the Corporation shall enter into any
          consolidation, merger or other transaction in which the shares of
          Common Stock are exchanged for or changed into other stock or
          securities, cash and/or any other property, then in each such case
          each share of $4.75 Preferred Stock remaining outstanding at the time
          of consummation of such transaction shall thereafter be convertible
          into the kind and

                                      12

          amount of such stock or securities, cash and/or other property
          receivable upon consummation of such transaction by a holder of the
          number of shares of Common Stock into which such shares of $4.75
          Preferred Stock might have been converted immediately prior to
          consummation of such transaction, assuming in each case that such
          holder of Common Stock failed to exercise rights of election, if any,
          as to the kind or amount of securities, cash or other property
          receivable upon consummation of such transaction (provided that if the
          kind or amount of securities, cash or other property receivable upon
          consummation of such transaction is not the same for each non-electing
          share, then the kind and amount of securities, cash or other property
          receivable upon consummation of such transaction for each non-electing
          share shall be deemed to be the kind and amount as receivable per
          share by a plurality of the non-electing shares).

               (VIII)  In the event of any Change in Control (as hereinafter
          defined) of the Corporation, each holder of $4.75 Preferred Stock
          shall have the right, at the holder's option, to require the
          Corporation to redeem all or any number of such holder's shares of
          $4.75 Preferred Stock during the period (the "Exercise Period")
          beginning on the 30th day and ending on the 90th day after the date of
          such Change in Control at the Redemption Price, plus accrued and
          unpaid dividends to the date fixed for redemption; provided, however,
          that such redemption right shall not be applicable in the case of any
          Change in Control of the Corporation which shall have been duly
          approved by the Continuing Directors (as hereinafter defined) during
          the period (the "Approval Period") prior to or within 21 days after
          the date on which such Change in Control shall have occurred.  As used
          herein, (a) "Acquiring Person" means any Person who is or becomes the
          Beneficial Owner, directly or indirectly, of 10% or more of the
          outstanding Common Stock, (b) "Beneficial Owner" has the meaning
          ascribed to such term in Rule 13d-3 adopted pursuant to

                                      13

          the Securities Exchange Act of 1934, as amended, (c) a "Change in
          Control" of the Corporation shall be deemed to have occurred at such
          time as (i) any Person is or becomes the Beneficial Owner, directly or
          indirectly, of 30% or more of the outstanding Common Stock or (ii)
          individuals who constitute the Continuing Directors cease for any
          reason to constitute at least a majority of the Board, (d) "Continuing
          Director" means any member of the Board who is not affiliated with an
          Acquiring Person and who was a member of the Board immediately prior
          to the time that the Acquiring Person became an Acquiring Person and
          any successor to a Continuing Director who is not affiliated with the
          Acquiring Person and is recommended to succeed a Continuing Director
          by a majority of Continuing Directors who are then members of the
          Board, and (e) "Person" means any individual, corporation,
          partnership, limited partnership, association, joint-stock company,
          trust, unincorporated organization, syndicate or group (as such terms
          are used in Section 13d-3 adopted pursuant to the Securities Exchange
          Act of 1934, as amended) or government or political subdivision
          thereof.

               On or before the seventh day after the termination of the
          Approval Period, the Corporation shall mail to all holders of record
          of the $4.75 Preferred Stock as of the last day of the Approval
          Period, at their respective addresses as the same shall appear on the
          books of the Corporation as of such date, a notice disclosing (i) the
          Change in Control, (ii) whether or not the Continuing Directors have
          approved the Change in Control, and (iii) if the Continuing Directors
          have not approved the Change in Control, the respective dates on which
          the Exercise Period commences and ends, the redemption price per share
          of the $4.75 Preferred Stock applicable hereunder and the procedure
          which the holder must follow to exercise the redemption right provided
          above.  The Corporation shall cause a copy of such notice to be
          published in a newspaper of general circulation in the Borough of
          Manhattan, New

                                      14

          York.  To exercise such redemption right, a holder of the $4.75
          Preferred Stock must deliver during the Exercise Period written notice
          to the Corporation (or an agent designated by the Corporation for such
          purpose) of the holder's exercise of such redemption right, and, to be
          valid, any such notice of exercise must be accompanied by each
          certificate evidencing shares of the $4.75 Preferred Stock with
          respect to which the redemption right is being exercised, duly
          endorsed for transfer.  On or prior to the seventh day after the close
          of the Exercise Period, the Corporation shall accept for payment all
          shares of $4.75 Preferred Stock properly surrendered to the
          Corporation (or an agent designated by the Corporation for such
          purpose) during the Exercise Period for redemption in connection with
          the valid exercise of such redemption right and shall cause payment to
          be made in cash for such shares of $4.75 Preferred Stock.

          (ix)  For the purposes of this resolution, any stock of any class or
classes of the Corporation shall be deemed to rank:

                (a)  prior to shares of the $4.75 Preferred Stock, either as to
dividends or upon liquidation, if the holders of stock of such class or classes
shall be entitled by the terms thereof to the receipt of dividends or of amounts
distributable upon liquidation, dissolution or winding up, as the case may be,
in preference or priority to the holders of shares of the $4.75 Preferred Stock;
 
                (b)  on a parity with shares of the $4.75 Preferred Stock, 
either as to dividends or upon liquidation, whether or not the dividend rates,
dividend payment dates or redemption or liquidation prices per share thereof be
different from those of the $4.75 Preferred Stock, if the holders of stock of
such class or classes shall be entitled by the terms thereof to the receipt of
dividends or of amounts distributable upon liquidation, dissolution or winding
up, as the case may be, in proportion to their respective dividend rates or
liquidation prices, without preference or priority of one over the other as
between the holders of such stock and

                                      15

the holders of shares of $4.75 Preferred Stock (the term "Parity Preferred
Stock" being used to refer to any stock on a parity with the shares of $4.75
Preferred Stock, either as to dividends or upon liquidation as the context may
require); and

          (c)  junior to shares of the $4.75 Preferred Stock, either as to
dividends or upon liquidation, if such class shall be Common Stock or if the
holders of the $4.75 Preferred Stock shall be entitled to the receipt of
dividends or of amounts distributable upon liquidation, dissolution or winding
up, as the case may be, in preference or priority to the holders of stock of
such class or classes.

          (x) The $4.75 Preferred Stock shall rank on a parity with the $2.21
Cumulative Preferred Stock, par value $1 per share, of the Corporation and the
Cumulative Convertible Preferred Stock, $3.50 Series, par value $1 per share, of
the Corporation, in each case as to dividends and upon liquidation.  The $4.75
Preferred Stock shall rank prior to the Series A Junior Participating Preferred
Stock, par value $1 per share, and all other shares of capital stock of the
Corporation outstanding at the time of issuance of the $4.75 Preferred Stock.

                        Pursuant to Section 151 of the

               General Corporation Law of the State of Delaware

                         ----------------------------

          The undersigned DOES HEREBY CERTIFY that the following resolution was
duly adopted on _________ __, 1995, by the Board of Directors (the "Board") of
The Williams Companies, Inc., a Delaware corporation (hereinafter called the
"Corporation"), in accordance with the provisions of Section 151 of the General
Corporation Law of the State of Delaware:

               RESOLVED that pursuant to authority expressly granted to and
     vested in the Board by provisions of the Restated Certificate of
     Incorporation of the Corporation (the "Certificate of Incorporation"), the
     issuance of a series of Preferred Stock, par value $1 per share (the
     "Preferred Stock"), which shall consist of up to 2,500,000 of the _________
     shares of Preferred Stock which the Corporation now has authority to issue,
     be, and the same hereby is, authorized, and the powers, designations,
     preferences and relative, participating, optional or other special rights,
     and the qualifications, limitations or

     restrictions  thereof, of the shares of such series (in addition to the
     powers, designations, preferences and relative, participating, optional or
     other special rights, and the qualifications, limitations or restrictions
     thereof, set forth in the Certificate of Incorporation which may be
     applicable to the Preferred Stock) are fixed as follows:

          (i)  The designation of such series of the Preferred Stock authorized
by this resolution shall be the $3.50 Cumulative Convertible Preferred Stock
(the "$3.50 Preferred Stock").  The total number of shares of the $3.50
Preferred Stock shall be 2,500,000.

          (ii)  Holders of shares of $3.50 Preferred Stock will be entitled to
receive, when and as declared by the Board out of assets of the Corporation
legally available for payment, an annual cash dividend of $3.50 per share,
payable in quarterly installments on February 1, May 1, August 1 and November 1,
commencing [the first such date following the Effective Time] (each a "dividend
payment date").  Dividends on the $3.50 Preferred Stock will be cumulative from
the date of initial issuance of shares of $3.50 Preferred Stock.  Dividends will
be payable to holders of record as they appear on the stock books of the
Corporation on such record dates, not more than 60 days nor less than 10 days
preceding the payment dates thereof, as shall be fixed by the Board.  When
dividends are not paid in full upon the $3.50 Preferred Stock and any other
Parity Preferred Stock (as defined in paragraph (ix)), all dividends declared
upon shares of Parity Preferred Stock will be declared pro rata so that in all
cases the amount of dividends declared per share on the $3.50 Preferred Stock
and such other Parity Preferred Stock shall bear to each other the same ratio
that accumulated and unpaid dividends per share on the shares of $3.50 Preferred
Stock and such other Parity Preferred Stock bear to each other.  Except as set
forth in the preceding sentence, unless full cumulative dividends on the $3.50
Preferred Stock have been paid, no dividends (other than in Common Stock of the
Corporation) may be paid or declared and set aside for payment or other
distribution made upon the Common Stock or on any other stock of the Corporation
ranking junior to or on a parity with the $3.50 Preferred Stock as to dividends,

                                       2

nor may any Common Stock or any other stock of the Corporation ranking junior to
or on a parity with the $3.50 Preferred Stock as to dividends be redeemed,
purchased or otherwise acquired for any consideration  (or any payment made to
or available for a sinking fund for the redemption of any shares of such stock;
provided, however, that any moneys theretofore deposited in any sinking fund
- --------  -------                                                           
with respect to any Preferred Stock of the Corporation in compliance with the
provisions of such sinking fund may thereafter be applied to the purchase or
redemption of such Preferred Stock in accordance with the terms of such sinking
fund regardless of whether at the time of such application full cumulative
dividends upon shares of the $3.50 Preferred Stock outstanding to the last
dividend payment date shall have been paid or declared and set apart for
payment) by the Corporation (except by conversion into or exchange for stock of
the Corporation ranking junior to the $3.50 Preferred Stock as to dividends).
Dividends payable on the $3.50 Preferred Stock for any period less than the full
dividend period will be computed on the basis of a 360-day year consisting of
twelve 30-day months.

          (iii)  The shares of $3.50 Preferred Stock shall rank prior to the
shares of Common Stock and of any other class of stock of the Corporation
ranking junior to the $3.50 Preferred Stock upon liquidation, so that in the
event of any liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary, the holders of the $3.50 Preferred Stock shall be
entitled to receive out of the assets of the Corporation available for
distribution to its stockholders, whether from capital, surplus or earnings,
before any distribution is made to holders of shares of Common Stock or any
other such junior stock, an amount equal to $50 per share (the "Liquidation
Preference" of a share of $3.50 Preferred Stock) plus an amount equal to all
dividends (whether or not earned or declared) accumulated and unpaid on the
shares of $3.50 Preferred Stock to the date of final distribution.  After
payment of the full amount of the Liquidation Preference and such dividends, the
holders of shares of $3.50 Preferred Stock will not be entitled to any further
participation in any distribution of assets by the Corporation.  If, upon any
liquidation, dissolution or winding up of the Corporation, the assets of the
Corporation, or proceeds thereof, distributable among the holders of shares of
Parity Preferred Stock

                                       3

shall be insufficient to pay in full the preferential amount aforesaid, then
such assets, or the proceeds thereof, shall be distributable among such holders
ratably in accordance with the respective amounts which would be payable on such
shares if all amounts payable thereon were payable in full.  For the purposes
hereof, neither a consolidation or merger of the Corporation with or into any
other corporation, nor a merger of any other corporation with or into the
Corporation, nor a sale or transfer of all or any part of the Corporation's
assets for cash or securities shall be considered a liquidation, dissolution or
winding up of the Corporation.

          (iv)  The shares of the $3.50 Preferred Stock will not be redeemable
prior to November 1, 1999.  On and after November 1, 1999, the $3.50 Preferred
Stock will be redeemable, in whole at any time or from time to time in part at
the option of the Corporation, upon not less than 30 nor more than 60 days'
notice, at the following redemption prices (the "Redemption Prices") per share
if redeemed during the twelve-month period beginning November 1 of the year
indicated below; plus, in each case, all dividends accrued and unpaid on the
$3.50 Preferred Stock up to the date fixed for redemption:

 
                                   Redemption
                                      Price
     Year                           Per Share
     ----                           ---------

1999...............................   $51.40
2000...............................    51.05
2001...............................    50.70
2002...............................    50.35
2003 and thereafter................    50.00

          In the event that the Corporation determines to redeem fewer than all
of the outstanding shares of the $3.50 Preferred Stock, the shares to be
redeemed shall be determined by lot or a substantially equivalent method.

          If a notice of redemption has been given pursuant to this paragraph
(iv) and if, on or before the date fixed for redemption, the funds necessary for
such redemption shall have been set aside by the Corporation, separate and apart
from its other funds, in trust for the pro rata benefit of the holders of the
shares so called

                                       4

for redemption, then, notwithstanding that any certificates for such shares have
not been surrendered for cancellation, on the redemption date dividends shall
cease to accrue on the shares of $3.50 Preferred Stock to be redeemed, and at
the close of business on the redemption date the holders of such shares shall
cease to be stockholders with respect to such shares and shall have no interest
in or claims against the Corporation by virtue thereof and shall have no voting
or other rights with respect to such shares, except the right to receive the
moneys payable upon such redemption, without interest thereon, upon surrender
(and endorsement, if required by the Corporation) of their certificates, and the
shares evidenced thereby shall no longer be outstanding.  Subject to applicable
escheat laws, any moneys so set aside by the Corporation and unclaimed at the
end of two years from the redemption date shall revert to the general funds of
the Corporation, after which reversion the holders of such shares so called for
redemption shall look only to the general funds of the Corporation for the
payment of the amounts payable upon such redemption.  Any interest accrued on
funds so deposited shall be paid to the Corporation from time to time.

          (v) The holders of shares of $3.50 Preferred Stock shall have no
voting rights whatsoever, except for any voting rights to which they may be
entitled under the laws of the State of Delaware, and except as follows:

               (I) If and whenever at any time or times dividends payable on the
          $3.50 Preferred Stock or on any other Preferred Stock shall have been
          in arrears and unpaid in an aggregate amount equal to or exceeding the
          amount of dividends payable thereon for six quarterly periods, then
          the holders of the Preferred Stock shall have, in addition to the
          other voting rights set forth herein, the exclusive right, voting
          separately as a class, to elect two directors of the Corporation, such
          directors to be in addition to the number of directors constituting
          the Board immediately prior to the accrual of such right, the
          remaining directors to be elected by the other class or classes of
          stock entitled to vote therefor at each meeting of stockholders held
          for the purpose of electing directors.  Such voting right shall

                                       5

          continue until such time as all cumulative dividends accumulated on
          all the Preferred Stock having cumulative dividends shall have been
          paid in full and until any noncumulative dividends payable on all the
          Preferred Stock having noncumulative dividends shall have been paid
          regularly for at least one year, at which time such voting right of
          the holders of the Preferred Stock shall terminate, subject to
          revesting at such time as there shall occur each and every subsequent
          event of default of the character indicated above.

               Whenever such voting right shall have vested, such right may be
          exercised initially either at a special meeting of the holders of the
          Preferred Stock, called as hereinafter provided, or at any annual
          meeting of stockholders held for the purpose of electing directors,
          and thereafter at each successive annual meeting.

               At such time when such voting right shall have vested in the
          holders of the Preferred Stock, and if such right shall not already
          have been initially exercised, a proper officer of the Corporation
          shall, upon the written request of the holders of record of 10 percent
          in number of shares of the Preferred Stock then outstanding, addressed
          to the Secretary of the Corporation, call a special meeting of the
          holders of the Preferred Stock and of any other class or classes of
          stock having voting power with respect thereto for the purpose of
          electing directors.  Such meeting shall be held at the earliest
          practicable date upon the notice required for annual meetings of
          stockholders at the place for holding of annual meetings of
          stockholders of the Corporation, or, if none, at a place designated by
          the Secretary of the Corporation.  If such meeting shall not be called
          by the proper officers of the Corporation within 30 days after the
          personal service of such written request upon the Secretary of the
          Corporation, or within 30 days after mailing the same within the
          United States of America, by registered mail,

                                       6

          addressed to the Secretary of the Corporation at its principal office
          (such mailing to be evidenced by the registry receipt issued by the
          postal authorities), then the holders of record of 10 percent in
          number of shares of the Preferred Stock then outstanding may designate
          in writing one of their number to call such meeting at the expense of
          the Corporation, and such meeting may be called by such person so
          designated upon the notice required for annual meetings of
          stockholders and shall be held at the same place as is elsewhere
          provided for in this subparagraph (I).  Any holder of the Preferred
          Stock shall have access to the stock books of the Corporation for the
          purpose of causing a meeting of stockholders to be called pursuant to
          the provisions of this paragraph.  Notwithstanding the provisions of
          this paragraph, however, no such special meeting shall be called
          during a period within 90 days immediately preceding the date fixed
          for the next annual meeting of stockholders.

               At any meeting held for the purpose of electing directors at
          which the holders of the Preferred Stock shall have the right to elect
          directors as provided herein, the presence in person or by proxy of
          the holders of 33-1/3 percent of the then outstanding shares of the
          Preferred Stock shall be required and be sufficient to constitute a
          quorum of the Preferred Stock for the election of directors by the
          Preferred Stock.  At any such meeting or adjournment thereof (A) the
          absence of a quorum of the holders of the Preferred Stock shall not
          prevent the election of directors other than those to be elected by
          the holders of the Preferred Stock and the absence of a quorum or
          quorums of the holders of other classes of capital stock entitled to
          elect such other directors shall not prevent the election of directors
          to be elected by the holders of the Preferred Stock and (B) in the
          absence of a quorum of the holders of any class of stock entitled to
          vote for the election of directors, a majority of the holders present
          in person or by proxy of such class shall have the power to

                                       7

          adjourn the meeting for the election of directors which the holders of
          such class are entitled to elect, from time to time, without notice
          other than announcement at the meeting, until a quorum shall be
          present.

               The directors elected pursuant to this subparagraph (I) shall
          serve until the next annual meeting or until their respective
          successors shall be elected and shall qualify; provided, however, that
                                                         --------  -------      
          when the right of the holders of the Preferred Stock to elect
          directors as herein provided shall terminate, the terms of office of
          all persons so elected by the holders of the Preferred Stock shall
          terminate, and the number of directors of the Corporation shall
          thereupon be such number as may be provided in the By-laws of the
          Corporation irrespective of any increase made pursuant to this
          subparagraph (I).

               So long as any shares of $3.50 Preferred Stock are outstanding,
          the By-laws of the Corporation shall contain provisions ensuring that
          the number of directors of the Corporation shall at all times be such
          that the exercise, by the holders of shares of $3.50 Preferred Stock
          and the holders of other Preferred Stock, of the right to elect
          directors under the circumstances provided in this subparagraph (I)
          will not contravene any provisions of the Corporation's Certificate of
          Incorporation or By-laws.

               (II)  So long as any shares of the $3.50 Preferred Stock remain
          outstanding, the Corporation will not, either directly or indirectly
          or through merger or consolidation with any other corporation, without
          the affirmative vote at a meeting or the written consent with or
          without a meeting of the holders of at least 66-2/3 percent in number
          of shares of the $3.50 Preferred Stock then outstanding, (A) create
          any class or classes of stock ranking prior to or on a parity with the
          $3.50 Preferred Stock either as to dividends or upon liquidation or
          increase the authorized

                                       8

          number of shares of any class or classes of stock ranking prior to or
          on a parity with the $3.50 Preferred Stock either as to dividends or
          upon liquidation, or create or authorize any obligation or security
          convertible into shares of stock of any class ranking prior to or on a
          parity with the Preferred Stock either as to dividends or upon
          liquidation, but may, without such consent, create or authorize
          obligations or securities convertible into shares of Preferred Stock,
          or (B) amend, alter or repeal any of the provisions of the Certificate
          of Incorporation (including this resolution) so as to affect adversely
          the preferences, special rights or powers of the $3.50 Preferred Stock
          or of the holders thereof.

          (vi) Except as provided in paragraph (v)(II), no consent of the
holders of the $3.50 Preferred Stock shall be required for (a) the creation of
any indebtedness of any kind of the Corporation, (b) the creation, or increase
or decrease in the amount, of any class or series of stock of the Corporation
not ranking prior to or on a parity with to the $3.50 Preferred Stock as to
dividends or upon liquidation or (c) any increase or decrease in the amount of
authorized Common Stock or any increase, decrease or change in the par value
thereof or in any other terms thereof.

          (vii)  Subject to the provisions of paragraph (iv) hereof, the Board
reserves the right by subsequent amendment of this resolution from time to time
to increase or decrease the number of shares which constitute the $3.50
Preferred Stock (but not below the number of shares thereof then outstanding)
and in other respects to amend this resolution within the limitations provided
by law, this resolution and the Certificate of Incorporation.

          (viii)  At the option of the holder thereof and upon surrender thereof
for conversion to the Corporation at the office of the Transfer Agent of the
Corporation's Common Stock in the Borough of Manhattan, the City of New York or
in the City of Tulsa, each share of $3.50 Preferred Stock will be convertible
(or if such share is called or surrendered for redemption, then in respect of
such share to and including, but not after,

                                       9

the redemption date) into fully paid and nonassessable shares of Common Stock at
the initial conversion rate of 1.5625 shares of Common Stock for each share of
$3.50 Preferred Stock, the conversion rate being subject to adjustment as
hereinafter provided:

                    (I)  In case the Corporation shall (A) pay a dividend in
               shares of its capital stock, (B) subdivide its outstanding shares
               of Common Stock into a greater number of shares, (C) combine its
               outstanding shares of Common Stock into a smaller number of
               shares, or (D) issue by reclassification of its shares of Common
               Stock any shares of its capital stock, the conversion rate in
               effect immediately prior thereto shall be adjusted so that the
               holder of a share of $3.50 Preferred Stock surrendered for
               conversion after the record date fixing stockholders to be
               affected by such event shall be entitled to receive upon
               conversion the number of such shares of Common Stock which he
               would have been entitled to receive after the happening of such
               event had such share of $3.50 Preferred Stock been converted
               immediately prior to such record date.  Such adjustment shall be
               made whenever any of such events shall happen, but shall also be
               effective retroactively as to shares of $3.50 Preferred Stock
               converted between such record date and the date of the happening
               of any such event.

                    (II)  In case the Corporation shall issue rights or warrants
               to all holders of its Common Stock entitling them to subscribe
               for or purchase shares of Common Stock at a price per share less
               than the Current Market Price Per Share (as defined in
               subparagraph (IV) below) of Common Stock at the record date
               mentioned below, the number of shares of Common Stock into which
               each share of $3.50 Preferred Stock shall thereafter be
               convertible shall be determined by multiplying the number of
               shares of Common Stock into which such

                                       10

               share of $3.50 Preferred Stock was theretofore convertible by a
               fraction, the numerator of which shall be the number of shares of
               Common Stock outstanding on the date of issuance of such rights
               or warrants plus the number of additional shares of Common Stock
               offered for subscription or purchase, and the denominator of
               which shall be the number of the shares of Common Stock
               outstanding on the date of issuance of such rights or warrants
               plus the number of shares which the aggregate offering price of
               the total number of shares so offered would purchase at such
               Current Market Price Per Share.  Such adjustment shall be made
               whenever such rights or warrants are issued, but shall also be
               effected retroactively as to shares of $3.50 Preferred Stock
               converted between the record date for the determination of
               stockholders entitled to receive such rights or warrants and the
               date such rights or warrants are issued.

                    (III) In case the Corporation shall distribute to all
               holders of its Common Stock evidences of its indebtedness or
               assets (excluding any cash dividend or distribution made out of
               current or retained earnings) or rights to subscribe other than
               as set forth in subparagraph (II) above, then in each such case
               the number of shares of Common Stock into which each share of
               $3.50 Preferred Stock shall thereafter be convertible shall be
               determined by multiplying the number of shares of Common Stock
               into which such share was theretofore convertible by a fraction,
               the numerator of which shall be the Current Market Price Per
               Share of the Common Stock on the record date fixed by the Board
               for such distribution, and the denominator of which shall be such
               Current Market Price Per Share of the Common Stock less the then
               fair market value (as determined by the Board, whose
               determination shall be conclusive) of the

                                       11

               portion of the assets, evidences of indebtedness or subscription
               rights so distributed applicable to one share of the Common
               Stock.  Such adjustment shall be made whenever any such
               distribution is made, but shall also be effective retroactively
               as to shares of $3.50 Preferred Stock converted between the
               record date for the determination of stockholders entitled to
               receive such distribution and the date such distribution is made.

                    (IV)  For the purpose of any computation under subparagraphs
               (II) and (III) above and (VI) below, the "Current Market Price
               Per Share of Common Stock at any date shall be deemed to be the
               average of the daily closing prices for the 15 consecutive
               trading days commencing 20 trading days before the day in
               question.  The closing price for each day shall be reported on
               the New York Stock Exchange-Composite Transactions Tape or as
               reported by any successor central market system.

                    (V)  No adjustment in the conversion rate shall be required
               unless such adjustment would require an increase or decrease of
               at least 1% in such rate; provided, however, that any adjustments
               which by reason of this subparagraph (V) are not required to be
               made shall be carried forward and taken into account in any
               subsequent adjustment.  All calculations under this paragraph
               (viii) shall be made to the nearest one-hundredth of a share.

                    (VI) No fractional shares or scrip representing fractional
               shares of Common Stock shall be issued upon the conversion of any
               share of $3.50 Preferred Stock.  If the conversion thereof
               results in a fraction, an amount equal to such fraction
               multiplied by the Current Market Price Per

                                       12

               Share of Common Stock (as defined in subparagraph (IV) above) as
               of the conversion date shall be paid to such holder in cash by
               the Corporation.

                    (VII)  In case the Corporation shall enter into any
               consolidation, merger or other transaction in which the shares of
               Common Stock are exchanged for or changed into other stock or
               securities, cash and/or any other property, then in each such
               case each share of $3.50 Preferred Stock remaining outstanding at
               the time of consummation of such transaction shall thereafter be
               convertible into the kind and amount of such stock or securities,
               cash and/or other property receivable upon consummation of such
               transaction by a holder of the number of shares of Common Stock
               into which such shares of $3.50 Preferred Stock might have been
               converted immediately prior to consummation of such transaction,
               assuming in each case that such holder of Common Stock failed to
               exercise rights of election, if any, as to the kind or amount of
               securities, cash or other property receivable upon consummation
               of such transaction (provided that if the kind or amount of
               securities, cash or other property receivable upon consummation
               of such transaction is not the same for each non-electing share,
               then the kind and amount of securities, cash or other property
               receivable upon consummation of such transaction for each non-
               electing share shall be deemed to be the kind and amount as
               receivable per share by a plurality of the non-electing shares).

                    (VIII)  In the event of any Change in Control (as
               hereinafter defined) of the Corporation, each holder of $3.50
               Preferred Stock shall have the right, at the holder's option, to
               require the Corporation to redeem all or any number of such
               holder's shares of $3.50 Preferred

                                       13

               Stock during the period (the "Exercise Period") beginning on the
               30th day and ending on the 90th day after the date of such Change
               in Control at the Redemption Price, plus accrued and unpaid
               dividends to the date fixed for redemption; provided, however,
               that such redemption right shall not be applicable in the case of
               any Change in Control of the Corporation which shall have been
               duly approved by the Continuing Directors (as hereinafter
               defined) during the period (the "Approval Period") prior to or
               within 21 days after the date on which such Change in Control
               shall have occurred.  As used herein, (a) "Acquiring Person"
               means any Person who is or becomes the Beneficial Owner, directly
               or indirectly, of 10% or more of the outstanding Common Stock,
               (b) "Beneficial Owner" has the meaning ascribed to such term in
               Rule 13d-3 adopted pursuant to the Securities Exchange Act of
               1934, as amended, (c) a "Change in Control" of the Corporation

or classes shall be entitled by the terms thereof to the receipt of dividends or
of amounts distributable upon liquidation, dissolution or winding up, as the
case may be, in proportion to their respective dividend rates or liquidation
prices, without preference or priority of one over the other as between the
holders of such stock and the holders of shares of $3.50 Preferred Stock (the
term "Parity Preferred Stock" being used to refer to any stock on a parity with
the shares of $3.50 Preferred Stock, either as to dividends or upon liquidation
as the context may require); and

          (c) junior to shares of the $3.50 Preferred Stock, either as to
dividends or upon liquidation, if such class shall be Common Stock or if the
holders of the $3.50 Preferred Stock shall be entitled to the receipt of
dividends or of amounts distributable upon liquidation, dissolution or winding
up, as the case may be, in preference or priority to the holders of stock of
such class or classes.

          (x) The $3.50 Preferred Stock shall rank on a parity with the $2.21

                             STOCK OPTION AGREEMENT

          STOCK OPTION AGREEMENT, dated as of December 12, 1994 (this
"Agreement"), by and between The Williams Companies, Inc., a Delaware
corporation ("Parent"), and Transco Energy Company, a Delaware corporation (the
"Company").

          WHEREAS, Parent, WC Acquisition Corp. (the "Purchaser") and the
Company propose to enter into an Agreement and Plan of Merger, dated as of the
date hereof (the "Merger Agreement"), which provides, among other things, that
Parent, on the terms and subject to the conditions thereof, will make a cash
tender offer (the "Offer") to acquire up to 24,600,000 shares of the Company's
common stock, par value $0.50 per share (the "Common Stock"), together with the
attached Company Rights (as defined in the Merger Agreement), and thereafter the
Purchaser will be merged with and into the Company (the "Merger"); and

          WHEREAS, as a condition to their willingness to enter into the Merger
Agreement, Parent and the Purchaser have required that the Company agree, and
the Company has agreed, to grant to Parent an option to purchase from the

Company up to 7,500,000 shares of Common Stock upon the terms and subject to the
conditions hereof.

          NOW, THEREFORE, to induce Parent and the Purchaser to enter into the
Merger Agreement, and in consideration of the mutual covenants and agreements
set forth therein and herein, the parties hereto agree as follows:

          1.  Grant of Option.  The Company hereby grants to Parent an
              ---------------                                         
irrevocable option (the "Option") to purchase up to 7,500,000 shares of Common
Stock (the "Option Shares") in the manner set forth below at a price of $17.50
per share (the "Purchase Price").

          2.  Exercise of Option.
              ------------------ 

          (a)  The Option may be exercised by Parent, in whole or in part, at
any time or from time to time following the occurrence of a Triggering Event (as
defined below) and prior to the fifteenth business day after termination of the
Merger Agreement (the "Expiration Date") provided that Parent or the Purchaser
are not in material breach of the Merger Agreement.

          (b)  In order to exercise the Option, Parent must send a written
notice (an "Exercise Notice") to the Company specifying the number of Option
Shares it will purchase and a date not earlier than five business days nor later
than fifteen business days from the date

                                       2

such notice is given for the closing of such purchase (an "Option Closing").
Upon receipt of an Exercise Notice, the Company will, subject to Section 5
hereof, be obligated to deliver Option Shares in accordance with Section 3 of
this Agreement, and Parent will be obligated to deliver the Purchase Price, on
the later of the date specified in the Exercise Notice or the first business day
thereafter on which the following conditions are satisfied:  (a) no preliminary
or permanent injunction or other order against the delivery of the Option Shares
issued by any federal or state court of competent jurisdiction in the United
States is in effect; and (b) any applicable waiting period under the Hart-Scott-
Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), and the
rules and regulations promulgated thereunder have expired or been terminated.
Each Option Closing will be held at the offices of Skadden, Arps, Slate, Meagher
& Flom, 919 Third Avenue, New York, New York  10022 on the date specified in the
Exercise Notice, unless another date or place is agreed to in writing by the
parties hereto.

          (c)  The term "Triggering Event" will mean the occurrence of any of
the following events:  (i) the Company accepts a proposal for or otherwise
engages in

                                       3

any Acquisition Transaction (as defined in the Merger Agreement) other than the
Offer or the Merger; (ii) the Board of Directors of the Company withdraws,
amends or modifies in a manner adverse to Parent its favorable recommendation of
the Offer or the Merger; or (iii) (x) any person publicly proposes an
Acquisition Transaction and (y) the Offer has expired in accordance with its
terms and the Merger Agreement and the Minimum Condition (as defined in the
Merger Agreement) fails to be satisfied; provided, however, that no Triggering
Event will occur if Parent or the Purchaser are in material breach of the Merger
Agreement.

          3.  Payment of Purchase Price and Delivery of Certificates.  At each
              ------------------------------------------------------          
Option Closing (a) against delivery of the Option Shares to be purchased free
and clear of all liens, claims, charges and encumbrances of any kind or nature
whatsoever, Parent will pay to the Company, by a certified or bank check payable
in immediately available funds to the Company or, at the Company's election, by
wire transfer of immediately available funds to an account specified by the
Company, an amount in cash equal to the product of the Purchase Price times the
number of the Option Shares purchased at such Option Closing, and (b) the
Company will deliver to Parent a

                                       4

certificate or certificates representing the number of Option Shares so
purchased in the denominations and in the name designated by Parent in its
Exercise Notice.  In the event that Parent acquires any Option Shares and within
one year following the date of purchase disposes of such shares (other than to a
wholly-owned subsidiary of Parent) through a sale, exchange, transfer, merger or
otherwise, for an amount per share which exceeds the Purchase Price by more than
$2.00 (the "Option Cap"), Parent will promptly return to the Company the amount
of such excess and thereby effect an upward adjustment to the Purchase Price.
Parent will not sell or otherwise dispose of Option Shares except in compliance
with the Securities Act and any applicable state securities law.

          4.  Registration Rights.  The Company will use its reasonable best
              -------------------                                           
efforts to effect, as promptly as possible after the request of Parent within
one year after the first Option Closing, the registration under the Securities
Act of 1933 (the "Securities Act") and any applicable states securities laws of
any part or all of the Option Shares, unless in the written opinion of counsel
to the Company, which opinion must reasonably be satisfactory to Parent,
registration under the Securities Act is not required for the sale and
distribution of such

                                       5

Option Shares at such time; provided, however, that Parent and its Affiliates
(as defined herein) will not be entitled to more than an aggregate of two
effective registration statements hereunder.  The registration effected under
this Section 4 will be effected at the Company's expense except for underwriting
commissions and the fees and expenses of counsel to Parent.  In the event of an
underwritten public offering, the Company will provide to the underwriters such
documentation (including certificates, opinions of counsel and "comfort" letters
from auditors) as are customary in connection with such offerings and as such
underwriters may reasonably require.  In connection with the registrations under
this Section 4, the parties will indemnify each other in the customary manner
and, in the case of an underwritten offering, the Company will indemnify Parent
and the underwriters, in the manner and to the extent as is customary in such
underwritten offerings.  The term "Affiliate" will have the meaning ascribed to
it in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), as in effect on the date hereof (the term "registrant" in said
Rule 12b-2 meaning in this case the Company).

          5.  Cancellation Rights.
              ------------------- 

                                       6

          (a)  Parent's Cancellation Right.  At any time the Option is
               ---------------------------                            
exercisable, Parent will have the right, upon prior written notice (a "Parent
Cash-out Notice") to the Company specifying the date of the closing (the
"Cancellation Closing") thereof (which date will not be earlier than ten
business days nor later than twenty business days after the receipt by the
Company of such Parent Cash-out Notice), to cause the Company to pay to Parent
in consideration for the cancellation of all or that part of the Option to be
cancelled, an aggregate cash cancellation price (the "Cancellation Price") equal
to the product of (i) the number of shares of Common Stock as to which the
Option is to be cancelled, multiplied by (ii) the excess (but in no event more
than the Option Cap) of (x) the Applicable Price (as defined below) over (y) the
Purchase Price.

          (b)  Company's Cancellation Right.  At any time after the Company
               ----------------------------                                
receives an Exercise Notice pursuant to Section 2(b), the Company will have the
right, upon prior written notice (a "Company Cash-out Notice" and, together with
any Parent Cash-out Notice, a "Cash-out Notice") to Parent not later than two
business days prior to the applicable Option Closing, specifying the date of the
Cancellation Closing thereof (which will not

                                       7

be earlier than five business days nor later than fifteen business days after
the receipt by Parent of the applicable Company Cash-out Notice), to pay to
Parent in consideration for the cancellation of all or that part of the Option
subject to such Exercise Notice, in lieu of delivering Option Shares, the
Cancellation Price with respect to the Option Shares subject to such Exercise
Notice.

          (c)  Cancellation Closing.  At any Cancellation Closing, the Company
               --------------------                                           
will pay to Parent the Cancellation Price for the number of Option Shares as to
which the Option is to be cancelled, by certified or bank check payable in
immediately available funds or, at Parent's election, by wire transfer of
immediately available funds to an account specified by Parent in exchange for
the cancellation of such portion of the Option.  The closing will be held at the
offices of Skadden, Arps, Slate, Meagher & Flom, 919 Third Avenue, New York, New
York  10022 on the date specified in the applicable Cash-out Notice, unless
another date or place is agreed to in writing by the parties hereto.

          (d)  Definition.  The "Applicable Price" will mean the average of the
               ----------                                                      
high and low sales prices (but in no event less than the Purchase Price) of the
shares of Common Stock as quoted on the New York Stock

                                       8

Exchange (the "NYSE"), or if not so quoted on the NYSE, then the average of the
high and low sales prices on the principal national securities exchange on which
such shares are listed, or if not so listed on any national securities exchange,
then the average of the high and low bid prices per share of Common Stock as
quoted on the National Association of Securities Dealers Automated Quotations
System, on the day prior to the date of the applicable Parent Cash-out Notice or
the applicable Exercise Notice, as the case may be (the "Measurement Date");
provided, however, that if any person has entered into an agreement with the
Company for an Acquisition Transaction, or an Acquisition Transaction has
otherwise been proposed, prior to the delivery of the applicable Cash-out
Notice, the Applicable Price shall mean the average consideration proposed to be
payable per outstanding share of Common Stock pursuant to such Acquisition
Transaction (or, if there is more than one such Acquisition Transaction,
pursuant to the Acquisition Transaction which yields the greater average
consideration) valued as of the Measurement Date (with any non-marketable
securities included in such consideration being valued at the fair market value
per share of such securities with such fair market value to be determined

                                       9

in good faith by an independent investment banking firm selected by the Company
and Parent).

          6.  Anti-Dilution Adjustments.  In the event of any change in the
              -------------------------                                    
number of issued and outstanding shares of Common Stock by reason of any stock
dividend, split-up, combination, recapitalization, merger or similar change in
the corporate or capital structure of the Company which would have the effect of
diluting the rights of Parent hereunder, the number and kind of Option Shares
subject to the Option, the Option Cap per share (but not the aggregate dollar
amount thereof) and the Purchase Price will be appropriately adjusted.

          7.  Filings and Consents.  Parent and the Company each will use its
              --------------------

Agreement.

          9.  Parties in Interest; Assignment.  No party to this Agreement may
              -------------------------------

written

                                       10

consent of the other parties hereto, except that the rights and obligations of
Parent hereunder may be assigned by Parent to any direct or indirect wholly-
owned subsidiary of Parent, but no such transfer will relieve Parent of its
obligations hereunder if such transferee does not perform such obligations.

          10.  Amendments.  This Agreement may not be modified, amended, altered
               ----------

               -------------

                              By:

                           CONFIDENTIALITY AGREEMENT
                           -------------------------

     THIS CONFIDENTIALITY AGREEMENT (this "Agreement"), entered into and made 
effective on the __ day of October, 1994, is by and between Transco Energy 
Company ("Transco") and The Williams Companies, Inc. ("Williams").

                             W I T N E S S E T H:

     WHEREAS, the parties hereto intend to enter into confidential discussions 
and may enter into negotiations with regard to the acquisition or combination of
certain stock or assets of Transco and/or Williams pursuant to terms and 
conditions mutually agreeable to Transco and Williams (the "Proposed 
Transaction");

     WHEREAS, it will be necessary for the parties or their Affiliates (as 
defined in Section 11)to release certain confidential information to each other 
for the sole purpose of enabling the parties to evaluate their interest in 
entering into the Proposed Transaction; and

     WHEREAS, the parties have entered into this Agreement in order to assure 
the confidentiality of all such information and to prevent the disclosure of 
same to third parties except as permitted herein and to address certain other 
matters.

     NOW, THEREFORE, in consideration of the mutual promises and covenants made 
herein, and with the intent to be legally bound hereby, Transco and Williams 
agree as follows:

     1.  Confidential Information.  The term "Confidential Information" as used 
         ------------------------
in this Agreement shall mean any and all written materials provided by a party 
or its Affiliates to the other or ascertained by the other through due diligence
investigation or discussions between employees or agents of the parties or their
Affiliates; such Confidential Information shall include but not be limited to, 
all marketing, technical, engineering, operational, economic or financial 
knowledge, information or data of any nature whatsoever relating to the future, 
present or past business, operations, plans or assets of the party, including 
any of its Affiliates, which is disclosed (either directly or through their 
agents) by such party or its Affiliates to the other in connection with the 
Proposed Transaction; such Confidential Information shall also include any 
analyses, compilations, data, studies or other documents prepared by a party or 
its Affiliates containing or based on, in whole or in part, Confidential 
Information relating to the other party, or reflecting a party's or its 
Affiliates' review of, or interest in, the other party or any of its Affiliates;
provided, however, that Confidential Information shall not include the 
following:

         (a)  information which at the time of disclosure by a party or its 
              Affiliates (the "Disclosing Party") is in the public domain, or
              information which later becomes part of the public domain through
              no act or omission of the recipient (the "Receiving Party");

         (b)  information which the Receiving Party can demonstrate was legally
              in its possession prior to disclosure by the Disclosing Party;

         (c)  information received by the Receiving Party from a third party 
              who, to the best of the Receiving Party's knowledge, did not
              acquire such information on a confidential basis either directly
              or indirectly from the Disclosing Party.

                                      -2-

     2.  Disclosure and Use of Confidential Information.  Each party agrees to 
         ----------------------------------------------
keep confidential all Confidential Information relating to the other party, and 
shall not, without the other party's prior written consent, disclose to any 
third party, firm, corporation or entity such Confidential Information.  Each 
party shall limit the disclosure of Confidential Information relating to the 
other party to only those directors, officers, employees and agents (including 
attorneys, accountants, investment bankers ("Financial Advisors") and similar 
consultants) of the party or its Affiliates reasonably necessary to evaluate the
Proposed Transaction.  In addition, each party shall inform such persons of the 
confidential nature of the Confidential Information and direct such persons to 
treat such information confidentially and to otherwise comply with the 
provisions of this Agreement, and each party shall be responsible for any breach
of this Agreement by any of such persons.  To the extent that any such persons 
are not employees of the party or its Affiliates, the party shall obtain a 
signed writing evidencing the acceptance by such persons of the terms of this
Agreement.  Each party shall use Confidential Information relating to the other
party only for the purpose of its internal evaluation of the Proposed 
Transaction, and shall not make any other use, in whole or in part, of any such 
Confidential Information without the prior written consent of the other.

     3.  Required Disclosure.  In the event that either Transco, Williams or any
         -------------------
of their respective Affiliates (as the case may be) are requested or required by
oral questions, interrogatories, requests for information or documents,
subpoena, civil investigative demand or similar process or by law or regulation
(1) to disclose any Confidential Information relating to the other or (2) to 
disclose the possibility of any Proposed Transaction or the discussions 
pertaining thereto, it is agreed that it will provide prompt notice of such 
potential disclosure so than an appropriate protective order may be sought 
and/or a waiver of compliance with the provisions of this Agreement may be 
granted.  If, in the absence of a protective order or the receipt of a waiver 
hereunder, Transco, Williams and/or any of their respective Affiliates (as the 
case may be) are nonetheless, in the written opinion of their respective 
counsel, legally required to disclose Confidential Information relating to the 
other or to disclose the possibility of any Proposed Transaction or the 
discussions pertaining thereto, then in such event Transco, Williams or the 
Affiliates (as the case may be) may disclose such information without liability
hereunder, provided that the other party has been given a reasonable opportunity
to review the text of such disclosure before it is made.

     4.  Return of Documents.  Upon written request from the Disclosing Party or
         -------------------
upon termination of the confidential discussions contemplated hereunder, Transco
and Williams shall each return any and all written Confidential Information
relating to the other as well as any other information disclosed to it by the
other party, including all originals, copies, translations, notes, or any other
form of said material. Notwithstanding the foregoing sentence, Transco or
Williams, as the case may be, may in lieu of returning the same to the
Disclosing Party destroy all documents, notes, memoranda, analyses or other
writings prepared by Transco or Williams, as the case may be, which are based on
or refer to any Confidential Information relating to the Disclosing Party and
certify such destruction in writing to the Disclosing Party.

     5.  Survival of Obligations.  The obligations and commitments established 
         -----------------------
by this Agreement shall remain in full force and effect for three (3) years from
the date of this Agreement or until such time as the parties have entered into 
an agreement providing otherwise.

     6.  Nature of Information.  Transco and Williams each hereby accepts the 
         ---------------------
representations of the other party that the other party's Confidential 
Information is of a special, unique, unusual, extraordinary, and intellectual 
character.  Transco and Williams each acknowledges that the Disclosing Party's
interests in such Confidential Information may be irreparably injured by 
disclosure of such Confidential Information.  Transco and Williams each 
acknowledges and agrees that money damages would not be a sufficient remedy for 
any breach of this Agreement by it and that in addition to all other remedies 
the other party shall be entitled to specific

                                      -3-
 
performance and injunctive or other equitable relief as a remedy for any such 
breach and each further agrees to waive any requirement for the securing or 
posting of any bond in connection with such remedy.

     7. Securities Laws. Each party hereby acknowledges that it is aware, and 
        ---------------
that it will advise its directors, officers, employees and agents who are 
informed as to the matters which are the subject of this Agreement, that the 
United States securities laws prohibit any person who has received from an 
issuer material, non-public information from purchasing or selling securities 
of such issuer or from communicating such information to any other person while 
such information is non-public under circumstances in which it is reasonably 
foreseeable that such person is likely to purchase or sell such securities.

     8. Other Transactions Excluded. Each party agrees that  until the 
        ---------------------------
expiration of three years from the date of this Agreement, neither it nor any of
its Affiliates (excluding the trustee or any  investment advisor of any of 
each party's pension plans) shall, directly or indirectly, alone or in concert 
with others, without the prior approval of the Board of Directors of the other 
party: (a) in any manner acquire, agree to acquire or make any proposal to 
acquire, directly or indirectly, any securities or property of the other party 
or any of its Affiliates (other than the acquisition of property in the 
ordinary course of business), (b) propose to enter into, directly or indirectly,
any merger or business combination involving the other party or any of its 
Affiliates, or to purchase, directly or indirectly, all or (other than in the 
ordinary course of business) any portion of the assets of the other party or 
any of its Affiliates, (c) make, or in any way participate, directly or 
indirectly, in any "solicitation" of "proxies" (as such terms are used in the 
proxy rules of the Securities and Exchange Commission) to vote, or seek to
advise or influence any person with respect to the voting of any voting
securities of the other party or any of its Affiliates, (d) form, join or in any
way participate in a "group" (within the meaning of Section 13(d) of the
Securities Exchange Act of 1934) with respect to any voting securities of the
other party or any of its Affiliates, (e) otherwise act, alone or in concert
with others, to seek to control or influence the management, Board of Directors
or policies of the other party, (f) disclose any intention, plan or arrangement
inconsistent with the foregoing or, (g) advise, assist or encourage any other
persons in connection with any of the foregoing, including arranging or in any
way participating, directly or indirectly, in the financing of the foregoing.
Each party also agrees during such period not to (i) request the other party (or
its directors, officers, employees or agents), directly or indirectly, to amend
or waive any provision of this Section 8 (including this sentence) or (ii) take
any action which might require the other party to make a public announcement
regarding the possibility of a business combination or merger.

     9. Contact by Parties. For a period of three years from the date of this 
        ------------------
Agreement, each party agrees not to initiate or maintain contact (except for 
those contacts made in the ordinary course of business) with any director, 
officer, employee or agent of the other party or its Affiliates regarding its 
business, operations, prospects or finances, except with the express written 
permission of the other party. It is understood that each party's Financial 
Advisors will arrange for appropriate contacts for due diligence purposes. It is
further understood that all (i) communications regarding the Proposed 
Transaction, (ii) requests for additional information, (iii) requests for 
facility tours or management meetings, and (iv) disclosures or questions 
regarding procedures, will be submitted or directed only to each party's 
Financial Advisors. Each party further agrees that for a period of one year from
the date hereof, without the prior written consent of the other party, which 
will not be unreasonably withheld, a party will not directly or indirectly 
knowingly or intentionally solicit for employment any person who is now employed
by the other party or its Affiliates, it being understood that an advertisement 
published in any newspaper, magazine or similar publication soliciting the 
employment of persons generally will not be deemed a solicitation prohibited by 
this sentence.

                                      -4-
 
    10.  Governing Law.  The validity and interpretation of this Agreement and 
         -------------
the legal relations of the parties to it shall be governed by the laws of the 
State of Delaware.  In the event that a court of competent jurisdiction 
determines that any portion of this Agreement is unreasonable because of its 
term or scope, or for any other reason, Transco and Williams agree that such 
court may reform such provision so that it is reasonable under the circumstances
and that such provision, as reformed, shall be enforceable.  We each hereby 
irrevocably and unconditionally consent to submit to the exclusive jurisdiction 
of the courts of the State of Delaware for any actions, suits or proceedings 
arising out of or relating to this Agreement and we each agree not to commence 
any action, suit or proceeding relating hereto except in such courts.  We 
further agree that service of any process, summons, notice or document by U.S. 
registered mail to our respective executive offices will be effective service of
process for any action, suit or proceeding brought in any such court.

    11.  Affiliate.  The term "Affiliate" shall mean any corporation, 
         ---------
partnership, or other entity or association that directly, or indirectly through
one or more intermediaries, controls, or is controlled by, or is under common 
control with, Transco or Williams (as the case may be).

    12.  No Other Agreement.  It is expressly understood that this Agreement is 
         ------------------
not and shall not be construed as any obligation or form of a letter of intent 
or agreement to enter into the Proposed Transaction.  Neither party may rely on 
this Agreement or the negotiations or exchange of Confidential Information or 
other documentation between the parties as a commitment to enter into binding 
definitive agreements.  Each party agrees that unless and until a definitive 
agreement between the parties hereto with respect to any Proposed Transaction 
has been executed and delivered, neither party will be under any obligation of 
any kind whatsoever with respect to a Proposed Transaction except for the 
matters specifically provided for in this Agreement.

    13.  No Representations or Warranties.  With respect to any information, 
         --------------------------------
including but not limited to Confidential Information, which either party 
furnishes or otherwise discloses to the other party for the purpose of 
evaluating any Proposed Transaction, it is understood and agreed that the party 
disclosing such information does not make any representations or warranties as 
to the accuracy, completeness or fitness for a particular purpose thereof.  It 
is further understood and agreed that neither party nor their representatives or
Affiliates shall have any liability or responsibility to the other party or to 
any other person or entity resulting from the use of any information so 
furnished or otherwise provided. 

    14.  Modification and Waiver.  The provisions of this Agreement may be 
         -----------------------
modified or waived only by a separate writing signed by Transco and Williams 
expressly so modifying or waiving the same.  No failure or delay by Transco or 
Williams in exercising any right, power or privilege hereunder shall operate as 
a waiver thereof, nor shall any partial exercise thereof preclude any other or 
further exercise thereof or of any other right, power or privilege.

    15.  Affiliates Bound.  Each of Transco or Williams agrees to cause its 
         ----------------
Affiliates to be bound hereby as if each were a party to this Agreement.

    16.  Severability.  If any provision of this Agreement is declared void, or 
         ------------
otherwise unenforceable and cannot be reformed as provided in Section 10 hereof,
such provision shall be deemed to have been severed from this Agreement, which 
shall otherwise remain in full force and effect.

                                     -5- 

     IN WITNESS WHEREOF, the parties hereto have entered into this Agreement on 
the day and year first herein above written.

                                   COMPLAINT
                                   ---------

     Plaintiff, by and through his attorneys, alleges as follows:

                                  THE PARTIES
                                  ----------- 

     1.  Plaintiff brings this action as a class action on behalf of himself and
all other shareholders of Transco Energy Company ("Transco") who are similarly 
situated to enjoin any and all efforts by the defendants to be acquired by 
Williams Companies Inc. ("Williams") by means of a coercive front-end loaded 
two-step tender offer/merger, to which Transco's directors have agreed in breach
of their fiduciary duties. Plaintiff further brings this action to enjoin any 
and all efforts by defendants to enforce any anti-takeover devices including the
lock-up option granted Williams described below. Plaintiff also seeks to 
recover damages from the director defendants for breach of fiduciary duty in 
connection with the proposed acquisition of Transco. Defendants' actions 
constitute a breach of fiduciary duty to inform themselves, to

 
maximize shareholder value, and to protect the interests of the public 
shareholders.  The director defendants are utilizing their fiduciary positions 
of control over Transco to agree to a coercive transaction when they should 
protect the public shareholders from such coercion.

     2.  Plaintiff is the owner of common stock of Transco.  

     3.  Defendant Transco is a Delaware corporation with its principal 
executive offices located at 2800 Post Oak Boulevard, P.O. Box 1396, Houston, TX
77251.  Transco transports and markets natural gas; develops and owns 
independent electric power generation facilities; mines, markets, and transports
coal; explores for oil and natural gas; and produces and sells natural gas 
liquids.

     4.  The following individual defendants (the "director defendants") 
constitute the entire Board of Directors of Transco; John P. Desbarres, Robert 
W. Fri, J. David Grissom, Benjamin F. Bailer, Gordon F. Ahalt, Frederick H. 
Schultz, and William H. Luers.

     5.  By reason of their relationships and offices, the director defendants 
are in a fiduciary relationship with plaintiff and other public shareholders of 
Transco and owe to them the highest obligations of good faith and fair dealing.

     6.  Defendant Williams is a Delaware corporation with subsidiaries that 
transport and sell natural gas and petroleum products; operate a digital fiber 
optic and microwave telecommunications system; and offer data, voice, and video 
related

                                       2

products and services. Williams is sued as an aider and abettor of the director
defendants' breaches of fiduciary duty described herein.

                           CLASS ACTION ALLEGATIONS
                           ------------------------   

     7.  Plaintiff brings this action on his own behalf and as a class action 
pursuant to Rule 23 of the rules of the Court of Chancery, on behalf of all 
common stockholders of Transco (except defendants herein and any person, firm, 
trust, corporation or other entity related to or affiliated with any of the 
defendants and except for all persons seeking to buy Transco as an entity, 
either by friendly or hostile means) who are being threatened with a coercive 
tender offer and deprived of the opportunity to maximize the value of their 
Transco stock by the wrongful acts of the defendants described herein (the 
"Class").

     8.  This action is properly maintainable as a class action for the 
following reasons:

         a.  The Class is so numerous that joinder of all Class members is 
impracticable. There are approximately 15,700 holders of shares of Transco 
common stock outstanding. Members of the Class are scattered throughout the 
United States. Furthermore, as the damage suffered by individual Class members 
may be small, the expense and burden of individual litigation makes it 
impossible for the Class members, individually, to redress wrongs done to them.

         b.  There are questions of law and fact which are common to the 
members of the Class and which predominate over any

                                       3

questions affecting only individual members, including whether the defendants 
have breached the fiduciary duties owed by them to plaintiff and members of the
Class by reason of:
 
              (i)  their agreement to a coercive two-step merger, which includes
a front-end loaded tender offer and a lock-up provision to prevent Transco
public shareholders from maximizing the value of their holdings;

             (ii)  engaging in plans and schemes unlawfully to thwart offers and
proposals from third parties; and

            (iii)  approving and causing Transco to agree to an onerous 
"lock-up" provision with Williams.

          c.  The claims of plaintiff are typical of the claims of the other 
members of the Class, and plaintiff has no interests that are adverse or 
antagonistic to the interests of the Class.

          d.  Plaintiff is a member of the Class, has sustained and will sustain
damages, is committed to the vigorous prosecution of this action and has 
retained competent counsel experienced in litigation of this nature. 
Accordingly, plaintiff is an adequate representative of the Class and will 
fairly and adequately protect the interests of the Class. There will be no 
difficulty in the management of this case as a class action.

          e.  The prosecution of separate actions by individual members of the 
Class would create a risk of inconsistent or varying adjudications with respect 
to individual members of the 

                                       4

Class that would establish incompatible standards of conduct for the party 
opposing the Class.

          f.  Defendants have acted and/or refused to act on grounds generally
applicable to the Class, thereby making appropriate final injunctive relief or 
corresponding declaratory relief with respect to the Class as a whole.

          g.  A class action is superior to the other available methods for 
adjudication of this controversy.

                            SUBSTANTIVE ALLEGATIONS
                            -----------------------
              
     9.  On or about December 12, 1994, defendants announced that Transco had 
agreed to be acquired by Williams in a two-step transaction. In the first step, 
Williams will make a tender offer for 60% of Transco's common shares at $17.50 
cash per share. Once Williams has control of Transco by means of the tender 
offer, the second step, "mop up" merger will go forward with the remaining 40% 
of Transco's common shares being exchanged for .625 of a share of Williams 
common stock for each remaining share of Transco stock. On December 9, 1994, the
last trading day before the announcement of the deal, Williams was trading at 
26-7/8 per share. Therefore, .625 of a Williams share had an unaffected market 
value of less than $16.80. Consequently, Transco shareholders will be coerced to
tender their shares in order to get the higher cash consideration in the tender 
offer for at least 60% of their shares rather than risk receiving the lower 
merger consideration for all of their shares in the merger if the coercive 
tender offer is successful.

                                       5

     10.  The gross unfairness of the merger consideration is clear. During the 
last 12 months, Transco has traded as high as 16 7/8 per share, higher than the 
offered second-step merger consideration. But because of the coercive nature of 
the transaction, Transco shareholders will be forced to tender regardless of 
whether they believe the price is unfair and inadequate. By agreeing to this 
structure, the director defendants have breached their fiduciary duties owed to 
plaintiff and the Class to protect them from such coercive, inadequate 
transactions. By proposing and agreeing to this structure, Williams knowingly 
participated in the director defendants' breach of fiduciary duties.
 
     11.  Also, as part of the transaction, the director defendants have agreed 
to a sweetheart "lock-up" deal with Williams, pursuant to which Williams may buy
up to 7.5 million additional Transco common shares at $17.50, representing over
15% of Transco stock. This lock-up option could be used to assure that Williams
gains control of Transco and can complete the second step merger even if the 
coercive tender offer is not completely effective. In addition, the lock-up is 
designed to discourage other bidders. Indeed, if Williams seeks to exercise the 
option, Transco would have to pay $2 per option share, $15 million total, in
cash to cancel the option.
 
     12.  If the coercive transaction and lock-up option are permitted to 
survive in the face of the director defendants' failure and refusal to pursue
the interests of the public 
 
                                       6

 
shareholders, the Company's shareholders who wish to avail themselves of bona  
                                                                         ----
fide offers to purchase their shares for fair value or who wish to reject the 
- ----
Williams transaction as unfair and inadequate would be deprived of the ability 
to do so.

     13.  By agreeing to the coercive transaction and to the lock-up option, the
director defendants, without shareholder approval, caused a fundamental shift of
power from Transco's shareholders to themselves. These actions permit the
directors to act as the prime negotiators of -- and, in effect, totally to
preclude -- any and all competing offers through their power to use the onerous
                    ---
lock-up option to discourage other bidders.

     14.  This fundamental shift of control of Transco's destiny from the hands 
of its shareholders to the hands of the director defendants results in a 
heightened fiduciary duty of the director defendants to consider, in good faith,
any third-party bid, and further requires the director defendants to pursue 
third party interest in acquiring Transco and to negotiate in good faith with 
bidders on behalf of Transco's shareholders.

     15.  The director defendants have breached their fiduciary duties by reason
of the acts and transactions complained of herein.

     16.  The lock-up option was not granted by an informed, disinterested board
motivated to encourage the bidding process and maximize value for the benefit of
the stockholders. The lock-up option was granted by the board to protect the 
coercive front-end
                                       7

loaded buyout, terminating any further opportunity for meaningful third-party 
bidding or meaningful stockholder choice.

     17.  Unless enjoined by this Court, the director defendants will continue 
to breach their fiduciary duties owed to plaintiff and the other members of the
Class to the irreparable harm of the Class, as aforesaid.

     18.  Williams knew or recklessly disregarded the facts set forth herein 
concerning the director defendants breaches of fiduciary duty. Nonetheless, 
Williams has participated in and advanced those breaches. Consequently, Williams
is liable as an aider and abettor of the breaches of fiduciary duty alleged 
herein.

     19.  Plaintiff and the Class have no adequate remedy at law.

  WHEREFORE, plaintiff demands judgment and  preliminary and permanent relief, 
including injunctive relief, in his favor and in favor of the Class and against 
defendants as follows:

  A.  Declaring that this action is properly maintainable as a class action.

  B.  Declaring that the director defendants and each of them have committed a 
gross abuse of trust and have breached their fiduciary duties to the Class.

  C.  Granting injunctive relief against the defendants' approval of the 
Williams transaction, against the completion of the coercive tender offer, 
against the enforcement of the lock-up option, and against any other actions 
that might be taken to, or have the effect of, diminishing shareholder value.

                                       8
  
     D.   Requiring the director defendants to fulfill their fiduciary duties to
maximize shareholder values by exploring third-party interest and accepting the
highest offer obtainable for the public shareholders or by permitting the
shareholders to make that decision free from any coercion.

     E.   Awarding plaintiff and the Class compensatory damages.

     F.   Awarding plaintiff the costs and disbursements of this action, 
including reasonable attorneys' and experts' fees.

     G.   Granting such other and further relief as this Court may deem just and
proper.

- ------------------------------------X

     Plaintiffs, by their attorneys, allege upon information and belief (said 
information and belief being based, in part, upon the investigation conducted by
and through their undersigned counsel), except with respect to their ownership
of Transco Energy Company ("Transco" or the "Company") common stock, which is
alleged upon their personal knowledge as follows:

                                  THE PARTIES
                                  -----------

     1.  Plaintiffs are the owners of shares of defendant Transco.

     2.  Defendant Transco is a corporation organized and existing under the 
laws of the State of Delaware. Transco maintains its principal offices at 2800 
Post Oak Boulevard, P.O. Box 1396, Houston, Texas. Transco

                                       1

 
transports natural gas through its two interstate pipeline systems, 10,500-mile 
Transcontinental Gas Pipe Line Corporation and 6,050-mile Texas Gas Transmission
Corporation, to markets in the eastern and midwestern United States, 
respectively.  Transco also buys, sells and arranges for the transportation of 
natural gas throughout the United States and Canada through its marketing 
subsidiary, Transco Gas Marketing Company.  Transco, through Interstate Coal 
Company, also mines coal in eastern Kentucky and Tennessee.

     3.  Defendant John P. Desbarres is the Chairman of the Board, President 
and Chief Executive Officer of Transco.

     4.  Defendants William H. Luers, Frederick H. Schultz, Gordon F. Ahalt,
Benjamin F. Bailar, Robert W. Fri and David J. Grissom are directors of 
Transco.

     5.  The foregoing individual defendants (collectively referred to herein as
the "Director Defendants") are in a fiduciary relationship with plaintiffs and 
the public stockholders of Transco, and owe plaintiffs and the other Transco 
public stockholders the highest obligations of good faith, fair dealing, due 
care, loyalty and full and candid disclosure.

                                       2

                           CLASS ACTION ALLEGATIONS

      6.  Plaintiffs bring this action on their own behalf and as a class action
on behalf of all shareholders of defendant Transco (except defendants herein
and any person, firm, trust, corporation or other entity related to or
affiliated with any of the defendants) or their successors in interest, who have
been or will be adversely affected by the conduct of defendants alleged herein.

      7.  This action is properly maintainable as a class action for the 
following reasons:

          (a)  the class of shareholders for whose benefit this action is 
brought is so numerous that joinder of all Class members is impracticable. As of
June 30, 1994, there were over 40 million shares of Transco common stock 
outstanding, owned by over 15,000 shareholders of record scattered throughout 
the United States.

          (b)  there are questions of law and fact which are common to members 
of the class and which include, inter alia, the following:
                                ----- ---- 

                (i)  whether the Director Defendants have breached their 
fiduciary duties owed by them to plaintiffs and members of the class and/or have
been aided and abetted in such breach;

                                       3

          (ii)  whether the Director Defendants have failed to fully disclose 
the true value of defendant Transco's assets and earnings power;

          (iii) whether the Director Defendants have wrongfully failed and 
refused to seek a purchaser of Transco and/or any and all of its various assets 
or divisions at the highest possible price; and

          (iv)  whether plaintiffs and the other members of the Class will be 
irreparably damaged by the Individual Defendants' failure to conduct an active 
auction of Transco.

     8.  Plaintiffs are committed to prosecuting this action and have retained 
competent counsel experienced in litigation of this nature. The claims of 
plaintiffs are typical of the claims of the other members of the Class and 
plaintiffs have the same interest as the other members of the Class. 
Accordingly, plaintiffs are adequate representatives of the Class and will 
fairly and adequately protect the interests of the Class.

                            SUBSTANTIVE ALLEGATIONS
                            -----------------------

     9.  On May 2, 1994 Smith Barney Shearson raised Transco to "buy" from 
"outperform."

    10.  On May 17, 1994, Desbarres stated at

                                       4

Transco's 46th Annual Meeting that Transco "is well on its way to achieving its 
vision of being the premier transporter and marketer in the eastern half of the 
United States." He further stated that, "Demand is growing in Transco's markets,
and we are not only keeping pace, but actually outdoing our competition in 
meeting customer needs. And I can not think of a better way for our company to 
achieve success."

     11.  On July 20, 1994, Transco announced its second quarter improved 
operating income which was the seventh consecutive quarter of improved operating
results.

     12.  On August 4, 1994, Transco announced organizational changes to better 
pursue development of new business and expand the reliance, quality services 
provided to its current customers. These changes refined the organization and 
increased the value of Transco.

     13.  On October 26, 1994, Transco announced its third quarter improved 
operating income. This was its eighth consecutive quarter of improved operating 
results.

     14.  Transco was on its way to becoming the premier transporter and 
marketer of natural gas in the eastern half of the United States before its 
public announcement on December 12, 1994.

     15.  On December 12, 1994, it was publicly

                                       5

announced that Transco has approved a merger between Transco and The Williams
Companies, Inc. ("Williams"). Under the terms of the merger agreement, Williams
will pay $17.50 cash a share for up to 24.6 million Transco shares or 60% of
Transco common stock and related common stock purchase rights in a first-step
tender offer. The tender offer will be conditioned on, among other things, the
tender of no fewer than 20.9 million shares, or 51% of Transco's common stock.
After the tender offer, a newly formed Williams unit will be merged into
Transco, with Transco continuing as a wholly owned subsidiary of Williams. The
outstanding shares of Transco $4.75 cumulative convertible preferred stock will
be converted into the right to receive an equal number of shares of a new series
of Williams $4.75 cumulative convertible preferred stock convertible into 0.5588
Williams common shares. The Transco $3.50 cumulative convertible preferred stock
will be converted into the right to receive an equal number of shares of a new
series of Williams $3.50 cumulative convertible preferred stock convertible into
1.5625 William common shares and otherwise having substantially equivalent
rights.
 
          16. In addition, Williams and Transco signed a stock option agreement
enabling Williams to buy up to 7.5 million additional Transco common shares at
$17.50 each. If Williams exercises the stock option, Transco has the right to
cancel the option for a cash payment not to exceed $2 per
 
                                       6

 
option share.
 
     17.  The total value of the cash tender offer and merger, including the 
exchange of new series of Williams convertible preferred stock for Transco's two
outstanding series of convertible preferred stock and including Transco's 
outstanding indebtedness, is approximately $3 billion. But because Transco 
shareholders do not know the value of the Williams securities to be paid on the 
"back-end" (particularly since the defendants have failed to establish a collar 
with respect to these securities), they will be coerced into tendering their 
shares on the front end of the offer for inadequate cash consideration.
 
     18.  Under the circumstances, the Director Defendants are obligated to 
explore all alternatives to maximize shareholder value. The Director Defendants 
will be in breach of their fiduciary duties owed to Transco's public
shareholders if they fail to fully explore bona fide offers by potential
                                           ---- ----                            
acquirors for the purchase of the Company.
 
     19.  The Williams proposal constitutes a change of control of Transco, its 
business and affairs.
 
     20.  Because of the announcement of the definitive merger agreement and the
structure of the transaction, no fair market check to determine the fair value 
of Transco's publicly held shares can be conducted. Moreover, defendants
 
                                       7

 
have set the price for the publicly held shares of Transco without taking 
adequate steps to determine the fair value of such securities.

     21.  The Director Defendants have violated fiduciary and other common law 
duties which they owe to plaintiffs and the other members of the Class in that 
they are not exercising informed independent business judgment, have acted and 
are acting to the detriment of the members of the Class in order to benefit 
themselves, and have participated in and substantially and knowingly aided and 
abetted the above breaches of fiduciary duty and the plan to effect a change of 
control of Transco on unfair and inadequate terms.

     22.  Because of their positions of control and authority as officers and 
directors of Transco, the Director Defendants were able to and did, directly or 
indirectly, control  the actions of Transco in agreeing to a merger on terms 
which are unfair to the shareholders of Transco. In violation of the fiduciary 
duties owed Transco's shareholders, the Director Defendants are causing, or are 
substantially and knowingly aiding and abetting in, the plan to enable Williams 
to acquire Transco to the detriment of plaintiffs and the plaintiff class.

     23.  Defendant Williams, without which the proposed transaction would not 
occur, and with knowledge of

                                       8

the individual defendants' breach of fiduciary duty, has aided and rendered 
substantial assistance to the individual defendants and stands to handsomely 
profit from the transaction.
 
          24.   Plaintiffs and the Class will suffer irreparable damage unless 
defendants are enjoined from breaching their fiduciary duties to maximize 
shareholder value.
 
          25.   Plaintiffs have no adequate remedy at law.  

WHEREFORE, plaintiffs demand judgment as follows:
 
          A.    Declaring this to be a proper class action;
 
          B.    Ordering defendants to carry out their fiduciary duties to 
plaintiffs and the other members of the Class by announcing their intention to:
 
                (i)  undertake an appropriate evaluation of alternatives 
designed to maximize value for Transco's public stockholders; and, 

                (ii) adequately ensure that no conflicts of interests exist 
between defendants' own interests and their fiduciary obligation to the public
stockholders or, if such conflicts exist, ensure that all such conflicts will be
resolved in the best interests of Transco's public stockholders.
 
                                       9

 
     C.  Enjoining consummation of the merger agreement;

     D. Directing that defendants pay to plaintiffs and the Class all damages
caused to them and account for all profits and any special benefits obtained as
a result of their unlawful conduct;

     E.  Awarding to plaintiffs the costs and disbursements of this action, 
including a reasonable allowance for the fees and expenses of plaintiffs' 
attorneys and expert; and

     F.  Granting such other and further relief as may be just and proper in the
premises.

                   Defendants.       :
- -------------------------------------X

     Plaintiff, by and through his attorneys, alleges as follows on information 
and belief, except for paragraph 1 which is alleged on knowledge:

                                    PARTIES
                                    -------

     1.  Plaintiff William Steiner is the owner of the common stock of Transco 
Energy Company ("Transco"), and has owned such stock at all relevant times.

     2.  Transco is a Delaware corporation based in Houston, Texas. It is a 
diversified energy company, owning and operating, through its subsidiaries, a 
natural gas pipeline in the United States. This pipeline system joins natural 
gas producing regions of the United States to markets in the Northeastern, 
Mid-Atlantic and Midwestern states. The Company also markets gas and mines for 
coal.

 
      3.  (a)  Defendant John P. DesBarres ("DesBarres") is and has been at all 
relevant times Chairman, President and Chief Executive Officer of the Company.

          (b) Defendants Gordon F. Ahalt, William H. Luers, Robert W. Fri,
Frederick H. Schultz, J. David Grissom, Benjamin F. Bailar, and Patricia L. 
Higgins are and have been at all relevant times directors of Transco.

      4.  Defendant The Williams Companies, Inc. ("Williams") also owns and 
operates natural gas and petroleum products pipelines. Williams transports 
natural gas through pipelines serving Louisiana and sixteen Western and
Midcontinent states, and transports petroleum products to eleven Midwestern 
states. Its principal executive offices are located in Tulsa, Oklahoma.

      5.  By virtue of the individual defendants' positions as directors and 
officers of Transco, said defendants were and are in a fiduciary relationship 
with plaintiff and the other public stockholders of the Company, and owe to 
plaintiff and the other members of the class the highest obligations of good 
faith and fair dealing.

                           CLASS ACTION ALLEGATIONS

      6.  Plaintiff brings this action for declaratory, injunctive and other 
relief on his own behalf and as a class action, pursuant to Rule 23 of the Rules
of the Court of Chancery on behalf of all common stockholders of Transco

                                     - 2 -

 
(except defendants herein and any person, firm, trust, corporation or other 
entity related to or affiliated with any of the defendants) or their successors
in interest, who are being deprived of the opportunity to maximize the value of 
their Transco shares by the wrongful acts of defendants as described herein.
 
      7.  This action is properly maintainable as a class action for the 
following reasons:
 
          (a)  The Class of stockholders for whose benefit this action is 
brought is so numerous that joinder of all Class members is impracticable. There
are approximately 40 million common shares of Transco outstanding, owned by over
thirty thousand stockholders. Members of the Class are scattered throughout the 
United States.
 
          (b)  There are questions of law and fact which are common to members 
of the Class, including whether the individual defendants have breached the 
fiduciary duties owed by them to plaintiff and members of the Class by reason of
the acts described herein, and whether Williams aided and abetted the commission
of such breaches.
 
          (c)  The claims of plaintiff are typical of the claims of the other 
members of the Class and plaintiff has no interests that are adverse or 
antagonistic to the interests of the Class.
 
          (d)  Plaintiff is committed to the vigorous prosecution of this action
and has retained competent counsel
 
                                     - 3 -

 

experienced in litigation of this nature. Accordingly, plaintiff is an adequate 
representative of the Class and will fairly and adequately protect the interests
of the Class.

     (e) The prosecution of separate actions by individual members of the Class
would create a risk of inconsistent or varying adjudications with respect to
individual members of the Class and establish incompatible standards of conduct 
for the party opposing the Class.
     
     (f)  Defendants have acted and are about to act on grounds generally 
applicable to the Class, thereby making appropriate final injunctive or 
corresponding declaratory relief with respect to the Class as a whole.
                                                            
                              FACTUAL BACKGROUND
                              ------------------     
     
     8.  On December 12, 1994, Transco and Williams announced that they had 
reached a definitive merger agreement pursuant to which Williams will acquire 
60% of the common stock of Transco through a cash tender offer of $17.50 per 
Transco share. The cash tender offer will be followed by a stock merger in which
shares of Transco common stock not purchased in the tender offer will be 
exchanged for 0.625 shares of Williams' common stock. The merger agreement has 
been approved by both Transco's and Williams' board of directors. The merger 
agreement constitutes a "change of control" requiring the individual defendants 
to maximize shareholder value.

                                     - 4 -

     9.  As part of the transaction, Williams and Transco also entered into a 
stock option agreement (the "lock-up option") providing for a grant of an option
to Williams to purchase, at $17.50 per share, up to 7.5 million additional 
shares of Transco common stock.

     10.  As reported by The Value Line Investment Survey, Transco's main 
pipeline subsidiary, Transcontinental Gas Pipeline Corp., is performing well, 
benefitting from a variety of factors including lower operating costs, reduced 
interest expense, and higher allowances on equity. The Company's gas marketing 
division's results are also improving, for which the net income has risen 
substantially on a year-over-year basis.

     11.  Expansion programs will play a major role in Transco's earnings growth
over the long haul. Currently, Transco is engaged in several pipeline and
storage projects that will increase the Company's service areas and
transportation capacity. Most of these programs are slated to be in operation by
1996. Finally, Transco's dividend yield is considered above average compared to
its industry peers, and its earnings potential remains strong.

     12.  By virtue of its due diligence negotiations with Transco and the 
merger agreement with the Company, Williams has been privy to material nonpublic
information concerning Transco's business and the desirability and value of 
same. Accordingly, Williams has positioned itself to 

                                    - 5 - 

purchase the outstanding shares of Transco at an unreasonably low and unfair
price to the detriment of plaintiff and the other public stockholders of the
Company. Such a merger between Transco and Williams would allow Williams,
without paying adequate consideration for Transco shares, to further strengthen
its position in the energy industry. 

          13. The transaction has been structured as a two-step transaction, the
first step being a tender offer for $17.50 per Transco share in cash, and the
second step being a merger for 0.625 shares of Williams stock per Transco
share. Since Transco shareholders do not know the value of the Williams
securities to be paid on the "back-end" (particularly since the defendants
have failed to establish a collar with respect to these securities), they will
be coerced into tendering their shares on the front end of the offer for
inadequate cash consideration.

          14.  Because of the announcement of the definitive merger agreement 
and the structure of the transaction, no fair market check to determine the fair
value of Transco's publicly held shares can be conducted.  Moreover, defendants 
have set the price for the publicly held shares of Transco without taking 
adequate steps to determine the fair value of such securities.

         15.   The actions taken by the individual defendants in entering into 
the merger agreement and the lock-up option are in gross disregard of the 
fiduciary duties owed to

                                     - 6 -

plaintiff and the other members of the Class, including their obligation to 
maximize shareholder value.
 
     16.  Defendant Williams, without which the proposed transaction would not 
occur, and with knowledge of the individual defendants' breach of fiduciary 
duty, has aided and rendered substantial assistance to the individual defendants
and stands to handsomely profit from the transaction.
 
     17.  Plaintiff and the other members of the Class will suffer irreparable 
injury unless the unlawful transactions complained of herein are enjoined.
 
     18.  Plaintiff and the Class have no adequate remedy at law.
 
     WHEREFORE, plaintiff demands judgment and preliminary and permanent relief,
including injunctive relief, in his favor and in favor of the Class and against
defendants as follows:
 
     A.  Declaring that this action is properly maintainable as a class action, 
and certifying plaintiff as class representative;
 
     B.  Declaring that the individual defendants and each of them have 
committed a gross abuse of trust and have breached their fiduciary duties to 
plaintiff and the other members of the Class;
 
     C.  Enjoining the tender offer and the merger;
 
                                     - 7 -

 
     D.  If the proposed transactions are consummated in whole or in part, 
rescinding the same or awarding rescissory damages to plaintiff and the Class;
 
     E.  Awarding plaintiff and the Class compensatory damages;
 
     F.  Awarding plaintiff the costs and disbursements of this action, 
including reasonable attorneys' and experts' fees; and
 
     G.  Granting such other and further relief as this Court may deem just and 
proper.

                   Defendants.       :
- -------------------------------------X
 
     Plaintiff, by his attorneys, alleges upon personal knowledge as to his own 
acts and upon information and belief as to all other matters, as follows:
 
     1.  Plaintiff brings this action individually and as a class action on 
behalf of all persons, other than defendants, who own the securities of Transco 
Energy Company ("Transco" or the "Company") and who are similarly situated (the 
"Class"), for injunctive and other relief. Plaintiff seeks, inter alia, to 
                                                            ----- ----         
enjoin consummation of a proposed transaction (the "transaction") announced on
December 12, 1994, pursuant to which The Williams Companies, Inc. ("Williams")
will make a cash tender offer to acquire up to 24.6 million shares, or 60%, of
Transco common stock and related common stock purchase rights for $17.50 per
share followed by a merger whereunder each remaining Transco share will be
exchanged for 0.625 shares of Williams common stock.
 
     2.  The proposed transaction and the acts of the individual defendants, as 
more particularly alleged herein,

 
constitute a breach of the individual defendants' fiduciary duties to plaintiff 
and the Class, aided and abetted by Williams.

     3.  The individual defendants' agreement to engage in the transaction was 
in breach of their fiduciary duties owed to Transco's stockholders to take all 
necessary steps to ensure that the stockholders will receive the maximum value 
realizable for their shares in any sale of control of the Company. In the 
context of this action, defendants were required to take all reasonable steps to
assure the maximization of stockholder value, including the implementation of a 
bidding mechanism to foster a fair auction of the Company to the highest bidder 
or the exploration of strategic alternatives that will return greater or 
equivalent value to plaintiff and the Class.

                                    Parties
                                    -------

     4.  Plaintiff is and, at all relevant times, has been the owner of shares 
of Transco common stock.

     5.  Transco is a corporation duly organized and existing under the laws of 
the State of Delaware. Transco is a holding company owning all the common shares
of Transcontinental Gas Pipe Line Corp., Texas Gas Transmission Corp., and 
several other companies engaged in natural gas transportation and gas related 
businesses. Transco maintains its principal executive offices at 2800 Post Oak 
Boulevard, Houston, Texas 77251. Transco has approximately 40.9 million shares 
of common stock outstanding and approximately 15,700 stockholders of record. 
Transco stock trades on the New York Stock Exchange.

                                       2

     6.  Defendant John P. DesBarres is Chief Executive Officer, President, and 
Chairman of the Board of Directors of Transco.  DesBarres' annual compensation 
is $888,662.

     7.   Defendants William H. Luers, Frederick H. Schultz, Gordon F. Ahalt, 
Benjamin F. Bailar, Robert W. Fri, and J. David Grissom are directors of 
Transco.

     8.   The defendants named in paragraphs 7 and 8 are hereinafter referred  
to as the "Individual Defendants."  

     9.   Because of their positions as officers/directors of the Company, the 
Individual Defendants owe fiduciary duties of loyalty and due care to plaintiff 
and the other members of the Class.

    10.   Each defendant herein is sued individually as a conspirator and aider 
and abettor, as well as in his capacity as an officer and/or director of the 
Company, and the liability of each arises from the fact that he has engaged in 
all or part of the unlawful acts, plans, schemes or transactions complained of 
herein.

                           CLASS ACTION ALLEGATIONS
                           ------------------------

    11.   Plaintiff brings this action in his own behalf and as a class action, 
pursuant to Rule 23 of the Rules of the Court of Chancery, on behalf of all 
stockholders of the Company, except defendants herein and any person, firm, 
trust, corporation, or other entity related to or affiliated with any of the 
defendants, who are and will be threatened with injury arising from defendants' 
actions as is described more fully below.

    12.   This action is properly maintainable as a class action.

                                       3

     13.  The Class is so numerous that joinder of all members is impracticable.
The Company has approximately 15,700 stockholders of record.
 
     14.  There are questions of law and fact common to the Class including, 
inter alia, whether: 
- ----- ----
 
          a.  the proposed transaction is grossly unfair to Transco's public 
stockholders;
 
          b.  defendants have engaged and are continuing to prevent plaintiff 
and the Class from receiving the maximum value per share that could be received 
in an unfettered market for control of Transco;
 
          c.  the individual defendants wrongfully failed or refused to obtain 
or attempt to obtain a purchaser for Transco for consideration more valuable
than the transaction contemplates;
 
          d.  defendants have breached or aided and abetted the breach of the 
fiduciary and other common law duties owed to plaintiff and the members of the
Class; and 
 
          e.  plaintiff and the other members of the Class would be irreparably 
damaged were the transaction complained of herein consummated;
 
     15.  Plaintiff is committed to prosecuting the action and has retained 
competent counsel experienced in litigation of this nature. Plaintiff's claims
are typical of the claims of the other members of the Class and plaintiff has
the same interests as the other members of the Class. Plaintiff is an adequate
representative of the Class.
 
     16.  The prosecution of separate actions by individual members of the Class
would create the risk of inconsistent or
 
                                       4

varying adjudications with respect to individual members of the Class which
would establish incompatible standards of conduct for defendants, or
adjudications with respect to individual members of the Class which would as a
practical matter be dispositive of the interest of the other members not parties
to the adjudications or substantially impair or impede their ability to protect
their interest.

     17.  The defendants have acted, or refused to act, on grounds 
generally applicable to, and causing injury to, the Class and, therefore, 
preliminary and final injunctive relief on behalf of the Class as a whole is 
appropriate.

                            SUBSTANTIVE ALLEGATIONS
                            -----------------------

     18.  By the acts, transactions, and courses of conduct alleged herein, 
defendants, individually and as part of a common plan and scheme and/or aiding 
and abetting one another are attempting to deprive plaintiff and the Class 
unfairly of the full value of their investment in Transco.

     19.  On December 12, 1994, the Dow Jones News Wire reported that Transco
                                    -------------------
has agreed to be acquired by Williams in a two-step merger transaction valued at
approximately $3 billion, which includes cash and the assumption of $2.3 billion
in debt and preferred stock.

     20.  Under the terms of the proposed Offer, during the first step of the 
two-step transaction, Transco stockholders will receive $17.50 per share of 
Transco stock they own.  Under the second-step, those shares not tendered will 
be exchanged for 0.625 of Williams common stock.

                                       5

     21.  Moreover, the outstanding shares of Transco $4.75 cumulative preferred
stock will be converted into the right to receive an equal number of shares of a
new series of Williams $4.75 cumulative preferred stock convertible into 0.5588 
Williams common shares.
 
     22.  Transco $3.50 cumulative convertible preferred stock will be converted
into the right to receive an equal number of shares of a new series of Williams 
$3.50 cumulative convertible preferred stock convertible into 1.5625 Williams 
common shares and otherwise having substantially equivalent rights.
 
     23.  At the conclusion of the tender offer, Williams will form a new unit 
that will merge into Transco, with Transco continuing as a wholly-owned 
subsidiary of Williams. Since Transco shareholders do not know the value of the 
Williams securities to be paid on the "back-end" (particularly since the 
defendants have failed to establish a collar with respect to these securities), 
they will be coerced into tendering their shares on the front end of the offer 
for inadequate cash consideration.
 
     24.  As part of the transaction, Transco signed a lock-up stock option with
Williams, providing Williams the right to purchase up to 7.5 million additional 
shares of Transco common stock at $17.50 per share. If, however, Williams 
exercises the stock option, Transco has the right to cancel the option for a 
cash payment not to exceed $2 per option.
 
     25.  Transco also agreed to pay to Williams a termination fee under certain
undisclosed circumstances, presumably which include the receipt or solicitation 
of other offers for the Company.
 
                                       6

 
     26.  Further, in an attempt to prevent others from making a bid for the 
Company, Williams will begin its tender for 60% of Transco's shares on Friday, 
December 16, 1994.
 
     27.  Because of the announcement of the definitive merger agreement and the
structure of the transaction, no fair market check to determine the fair value 
of Transco's publicly held shares can be conducted. Moreover, defendants have 
set the price for the publicly held shares of Transco without taking adequate 
steps to determine the fair value of such securities.
 
     28.  Defendants chose to pursue this transaction at a time when Transco is 
poised to significantly increase future earnings and when its value is believed 
to be far in excess of the consideration offered in the transaction.
 
     29. Indeed, on July 20, 1994, Transco announced improved results for the
second quarter ended June 30, 1994. For the quarter, Transco reported net income
of $2.5 million, or $0.6 per share, compared with $1.4 million, or $0.4 per
share, in the prior year. Transco attributed its improved second quarter results
to improved financial results of Transco Gas Marketing Co. and Transcontinental
Gas Pipe Line Corp. and lower financing costs. Commenting on the improved
quarterly results, defendant DesBarres stated, "We're pleased with our second
quarter results and particularly with the improved results from the gas
marketing segment... These results once again confirm our continuing progress
                     --------------------------------------------------------  
toward improving net income and returning the gas marketing segment to
- ----------------------------------------------------------------------         
profitability." [Emphasis added.]
- ---------------                                                                 
 
     30.  On October 26, 1994, Transco reported its results the quarter ended 
September 30, 1994. For the quarter, the Company
 
                                       7

 
reported a net loss of $4.6 million, or $0.11 per share, compared to a net loss
of $18.0 million, or $0.46 per share, in the same quarter during the prior year.
Excluding charges in both periods, Transco reported a net loss of $0.1 million,
or less than $0.01 per share, in the third quarter of 1994, compared with a net
loss of $2.3 million, or $0.06 per share, for the 1993 third quarter. Commenting
on the Company's third quarter results, defendant DesBarres stated, "We
attribute Transco's improved results over those of last year's third quarter
primarily to the continued strong performance or Transcontinental Gas Pipe Line
Corporation (TGPL), the improved financial performance of Transco Gas Marketing
Company (TGMC) and lower financing costs."
 
      31.  Defendant DesBarres also stated,
 
      Although marketing reported a loss, we're pleased with the continuing
      improvement in that business, particularly in view of the weak gas price
      environment during the quarter. The pipelines are continuing their solid
      performance, despite Texas Gas' lower earnings, which is due, in part, to
      the seasonality of the demand revenues under the provisions of our Order
      636 services. It is further attributed to an exceptionally strong third
      quarter in 1993 that reported a high level of interruptible transportation
      volumes on Texas Gas prior to implementation of Order 636. These
                                                                 -----          
      results once again confirm our continuing progress toward improved net
      ----------------------------------------------------------------------    
      income and returning marketing to profitability this year. [Emphasis
      ----------------------------------------------------------                
      added.]
 
      32. Defendants' knowledge and economic power and that of the investing
public is unequal because they are in possession of material non-public
information concerning the Company's assets, businesses, and future prospects.
This disparity makes it inherently unfair for the individual defendants to agree
to
 
                                       8

 
transfer ownership of Transco from its public stockholders to Williams at such 
an unfair and grossly inadequate consideration.
 
     33.  The consideration to be paid to the public shareholders in the 
transaction is grossly unfair, inadequate, and substantially below the fair or 
inherent value of the Company. The intrinsic value of the equity of Transco is 
materially greater than the consideration being offered, taking into account 
Transco's asset value, liquidation value, its expected growth, the strength of 
its business, and its revenues and cash flow and earnings power.
 
     34.  The individual defendants, in violation of their fiduciary obligations
to maximize stockholder value, have not considered seriously other potential 
purchasers of Transco or its stock in a manner designed to obtain the highest 
possible price for Transco public stockholders.
 
     35.  The proposed Offer is wrongful, unfair, and harmful to Transco public 
stockholders, and will deny Class members their right to share proportionately 
in the true value of Transco's valuable assets, profitable business, and future 
growth in profits and earnings.
 
     36.  Defendant Williams, without which the proposed transaction would not 
occur, and with knowledge of the individual defendants' breach of fiduciary 
duty, has aided and rendered substantial assistance to the individual defendants
and stands to handsomely profit from the transaction.
 
     37.  By reason of the foregoing, defendants herein have willfully 
participated in unfair dealing toward plaintiff and the other members of the 
Class and have engaged in and substantially
 
                                       9

 
assisted and aided and abetted each other in breach of the fiduciary duties 
owed to the Class.

     38.  Unless enjoined by this Court, defendants will continue to breach 
their fiduciary duties owed to plaintiff and the Class, and will succeed in 
their plan to deprive plaintiff and the Class of their fair proportionate share 
of Transco's valuable assets and businesses, all to the irreparable harm of the 
Class.

     39.  Plaintiff and the Class have no adequate remedy or law.

     WHEREFORE, plaintiff prays for judgment and relief as follows:

          a.  declaring that this lawsuit is properly maintainable as a class 
action and certifying plaintiff as representative of the Class;

          b.  declaring that the defendants and each of them have committed or 
aided and abetted a gross abuse of fiduciary duties owed to plaintiff and the 
other members of the Class;

          c.  preliminarily and permanently enjoining defendants and all persons
acting under, in concert with, or for them, from proceeding with, consummating 
or closing the transaction;

          d.  in the event the transaction is consummated, rescinding it and 
setting it aside;

          e.  awarding rescissory and/or compensatory damages against 
defendants, jointly and severally, in an amount to be determined at trial, 
together with prejudgment interest at the maximum rate allowable by law;

                                      10

          f.  awarding plaintiff and the Class their costs and disbursements and
reasonable allowances for plaintiff's counsel and experts' fees and expenses; 
and

          g.  granting such other and further relief as may be just and proper.

          Plaintiffs, by their attorneys, allege upon information and belief 
(said information and belief being based, in part, upon the investigation 
conducted by and through their undersigned counsel), except with respect to 
their ownership of Transco Energy Company ("Transco" or the "Company") common
stock, which is alleged upon their personal knowledge as follows:

                                  THE PARTIES
                                  -----------

          1.  Plaintiffs are the owners of shares of defendant Transco.

          2.  Defendant Transco is a corporation organized and existing under 
the laws of the State of Delaware.  Transco maintains its principal offices at
2800 Post Oak Boulevard,

                                       1

P.O. Box 1396, Houston, Texas. Transco transports natural gas through its two
interstate pipeline systems, 10,500-mile Transcontinental Gas Pipe Line
Corporation and 6,050-mile Texas Gas Transmission Corporation, to markets in
the eastern and midwestern United States, respectively. Transco also buys, sells
and arranges for the transportation of natural gas throughout the United States
and Canada through its marketing subsidiary, Transco Gas Marketing Company.
Transco, through Interstate Coal Company, also mines coal in eastern Kentucky
and Tennessee.

          3.  Defendant John P. Desbarres is the Chairman of the Board,
President and Chief Executive Officer of Transco.

          4.  Defendants William H. Luers, Frederick H. Schultz, Gordon F.
Ahalt, Benjamin F. Bailar, Robert W. Fri and David J. Grissom are directors of
Transco.

          5.  The foregoing individual defendants (collectively referred to
herein as the "Director Defendants") are in a fiduciary relationship with
plaintiffs and the public stockholders of Transco, and owe plaintiffs and the
other Transco public stockholders the highest obligations of good faith, fair
dealing, due care, loyalty and full and candid disclosure.

                                       2

                           CLASS ACTION ALLEGATIONS
                           ------------------------

          6.  Plaintiffs bring this action on their own behalf and as a class 
action on behalf of all shareholders of defendant Transco (except defendants 
herein and any person, firm, trust, corporation or other entity related to or 
affiliated with any of the defendants) or their successors in interest, who have
been or will be adversely affected by the conduct of defendants alleged herein.

          7.  This action is properly maintainable as a class action for the 
following reasons:

              (a)  the class of shareholders for whose benefit this action is 
brought is so numerous that joinder of all Class members is impracticable.  As 
of June 30, 1994, there were over 40 million shares of Transco common stock 
outstanding, owned by over 15,000 shareholders of record scattered throughout
the United States.

              (b)  there are questions of law and fact which are common to 
members of the class and Which include, inter alia, the following:
                                        ----- ----
                   (i)  whether the Director Defendants have breached their 
fiduciary duties owed by them to plaintiffs and members of the class and/or have
been aided and abetted in such breach;

                                       3

 
                     (ii) whether the Director Defendants have failed to fully 
disclose the true value of defendant Transco's assets and earnings power;

                    (iii) whether the Director Defendants have wrongfully failed
and refused to seek a purchaser of Transco and/or any and all of its various 
assets or divisions at the highest possible price; and

                     (iv) whether plaintiffs and the other members of the Class 
will be irreparably damaged by the Individual Defendants' failure to conduct an 
active auction of Transco.

          8.  Plaintiffs are committed to prosecuting this action and have 
retained competent counsel experienced in litigation of this nature. The claims 
of plaintiffs are typical of the claims of the other members of the Class and 
plaintiffs have the same interest as the other members of the Class. 
Accordingly, plaintiffs are adequate representatives of the Class and will 
fairly and adequately protect the interests of the Class.

                            SUBSTANTIVE ALLEGATIONS
                            -----------------------

          9.  On May 2, 1994 Smith Barney Shearson raised Transco to "buy" from 
"outperform."

                                       4

         10.  On May 17, 1994, Desbarres stated at Transco's 46th Annual Meeting
that Transco "is well on its way to achieving its vision of being the premier 
transporter and marketer in the eastern half of the United States."  He further 
stated that, "Demand is growing in Transco's markets, and we are not only 
keeping pace, but actually outdoing our competition in meeting customer needs.  
And I can not think of a better way for our company to achieve success."

         11.  On July 20, 1994, Transco announced its second quarter improved 
operating income which was the seventh consecutive quarter of improved operating
results.

         12.  On August 4, 1994, Transco announced organizational changes to 
better pursue development of new business and expand the reliance, quality 
services provided to its current customers.  These changes refined the 
organization and increased the value of Transco.

         13.  On October 26, 1994, Transco announced its third quarter improved 
operating income.  This was its eighth consecutive quarter of improved operating
results.

         14.  Transco was on its way to becoming the premier transporter and 
marketer of natural gas in the eastern half of the United States before its 
public announcement on December 12, 1994.

                                       5

         15.  On December 12, 1994, it was publicly announced that Transco had 
approved a merger between Transco and The Williams Companies, Inc. ("Williams").
Under the terms of the merger agreement, Williams will pay $17.50 cash a share 
for up to 24.6 million Transco shares or 60% of Transco common stock and related
common stock purchase rights in a first-step tender offer. The tender offer will
be conditioned on, among other things, the tender of no fewer than 20.9 million 
shares, or 51% of Transco's common stock. After the tender offer, a newly formed
Williams unit will be merged into Transco, with Transco continuing as a wholly 
owned subsidiary of Williams. The outstanding shares of Transco $4.75 cumulative
convertible preferred stock will be converted into the right to receive an equal
number of shares of a new series of Williams $4.75 cumulative convertible
preferred stock convertible into 0.5588 Williams common shares. The Transco
$3.50 cumulative convertible preferred stock will be converted into the right to
receive an equal number of shares of a new series of Williams $3.50 cumulative
convertible preferred stock convertible into 1.5625 Williams common shares and
otherwise having substantially equivalent rights.

         16.  In addition, Williams and Transco signed a stock option agreement 
enabling Williams to buy up to 7.5 million additional Transco common shares at 
$17.50 each. If Williams exercises the stock option, Transco has the right to

                                       6

cancel the option for a cash payment not to exceed $2 per option share.

         17.  The total value of the cash tender offer and  merger, including 
the exchange of new series of Williams convertible preferred stock for Transco's
two outstanding series of convertible preferred stock and including Transco's 
outstanding indebtedness, is approximately $3 billion. But because Transco 
shareholders do not know the value of the Williams securities to be paid on the 
"back-end" (particularly since the defendants have failed to establish a collar 
with respect to these securities), they will be coerced into tendering their 
shares on the front end of the offer for inadequate cash consideration.

         18. Under the circumstances, the Director Defendants are obligated to
explore all alternatives to maximize shareholder value.  The Director Defendants
will be in breach of their fiduciary duties owed to Transco's public 
shareholders if they fail to fully explore bona fide offers by potential 
                                           ---- ---- 
acquirors for the purchase of the Company.

         19.  The Williams proposal constitutes a change of control of Transco, 
its business and affairs.

         20.  Because of the announcement of the definitive merger agreement and
the structure of the transaction, no fair market check to determine the fair
value of Transco's publicly

                                       7

 
held shares can be conducted.  Moreover, defendants have set the price for the 
publicly held shares of Transco without taking adequate steps to determine the 
fair value of such securities.

         21.  The Director Defendants have violated fiduciary and other common 
law duties which they owe to plaintiffs and the other members of the Class in 
that they are not exercising informed independent business judgment, have acted 
and are acting to the detriment of the members of the Class in order to benefit 
themselves, and have participated in and substantially and knowingly aided and 
abetted the above breaches of fiduciary duty and the plan to effect a change of 
control of Transco on unfair and inadequate terms.

         22.  Because of their positions of control and authority as officers 
and directors of Transco, the Director Defendants were able to and did, directly
or indirectly, control the actions of Transco in agreeing to a merger on terms 
which are unfair to the shareholders of Transco. In violation of the fiduciary 
duties owed Transco's shareholders, the Director Defendants are causing, or are 
substantially and knowingly aiding and abetting in, the plan to enable Williams 
to acquire Transco to the detriment of plaintiffs and the plaintiff class.

         23.  Defendant Williams, without which the proposed transaction would 
not occur, and with knowledge of the 

                                       8

individual defendant's breach of fiduciary duty, has aided and rendered 
substantial assistance to the individual defendants and stands to handsomely 
profit from the transaction.

         24.  Plaintiffs and the Class will suffer irreparable damage unless 
defendants are enjoined from breaching their fiduciary duties to maximize 
shareholder value.

         25.  Plaintiffs have no adequate remedy at law.

         WHEREFORE, plaintiffs demand judgment as follows:

         A.   Declaring this to be a proper action;

         B.   Ordering defendants to carry out their fiduciary duties to 
plaintiffs and the other members of the Class by announcing their intention to:

              (i)  undertake an appropriate evaluation of alternatives designed 
to maximize value for Transco's public stockholders; and

              (ii) adequately ensure that no conflicts of interests exist 
between defendants' own interests and their fiduciary obligation to the public 
stockholders or, if such conflicts exist, ensure that all such conflicts will be
resolved in the best interests of Transco's public stockholders.

         C.   Enjoining consummation of the merger agreement;

                                       9

 
          D.  Directing that defendants pay to plaintiffs and the Class all 
damages caused to them and account for all profits and any special benefits 
obtained as a result of their unlawful conduct;

          E.  Awarding to plaintiffs the costs and disbursements of this action,
including a reasonable allowance for the fees and expenses of plaintiffs' 
attorneys and expert; and

          F.  Granting such other and further relief as may be just and proper 
in the premises.

                                                 CLASS ACTION 
     - v. -                                      COMPLAINT
                                                 ------------
JOHN P. DesBARRES, GORDON F. AHALT,

FREDERICK H. SCHULTZ, J. DAVID
GRISSOM, BENJAMIN F. BAILAR,
PATRICIA L. HIGGINS, TRANSCO ENERGY
COMPANY and THE WILLIAMS COMPANIES,
INC.,

               Defendants. 
- -------------------------------------------

          Plaintiff, by and through his attorneys, alleges as follows on
information and belief, except for paragraph 1 which is alleged on knowledge:

                                    PARTIES
                                    -------

          1.  Plaintiff is the owner of the common stock of Transco Energy
Company ("Transco"), and has owned such stock at all relevant times.

          2.  Transco is a Delaware corporation based in Houston, Texas. It is a
diversified energy company, owning and operating, through its subsidiaries, a
natural gas pipeline in the United States. This pipeline system joins natural
gas producing regions of the United States to markets

in the Northeastern, Mid-Atlantic and Midwestern states.  The Company also 
markets gas and mines for coal.

          3.  (a)  Defendant John P. DesBarres ("DesBarres") is and has been at 
all relevant times Chairman, President and Chief Executive Officer of the 
Company.

              (b)  Defendants Gordon F. Ahalt, William H. Luers, Robert W. Fri,
Frederick H. Schultz, J. David Grissom, Benjamin F. Bailar, and Patricia L. 
Higgins are and have been at all relevant times directors of Transco.

          4.  Defendant The Williams Companies, Inc. ("Williams") also owns and 
operates natural gas and petroleum products pipelines.  Williams transports 
natural gas through pipelines serving Louisiana and sixteen Western and 
Midcontinent states, and transports petroleum products to eleven Midwestern 
states.  Its principal executive offices are located in Tulsa, Oklahoma.

          5.  By virtue of the individual defendants' positions as directors and
officers of Transco, said defendants were and are in a fiduciary relationship 
with plaintiff and the other public stockholders of the Company, and owe to 
plaintiff and the other members of the class the highest obligations of good 
faith and fair dealing.

                           CLASS ACTION ALLEGATIONS
                           ------------------------

          6.  Plaintiff brings this action for declaratory, injunctive and other
relief on his own behalf and as a class

                                     - 2 -

action, pursuant to Rule 23 of the Rules of the Court of Chancery on behalf of 
all common stockholders of Transco (except defendants herein and any person, 
firm, trust, corporation or other entity related to or affiliated with any of 
the defendants) or their successors in interest, who are being deprived of the 
opportunity to maximize the value of their Transco shares by the wrongful acts 
of defendants as described herein.

          7.  This action is properly maintainable as a class action for the 
following reasons:

              (a)  The Class of stockholders for whose benefit this action is 
brought is so numerous that joinder of all Class members is impracticable. There
are approximately 40 million common shares of Transco outstanding, owned by over
thirty thousand stockholders. Members of the Class are scattered throughout the 
United States.

              (b)  There are questions of law and fact which are common to 
members of the Class, including whether the individual defendants have breached 
the fiduciary duties owed by them to plaintiff and members of the Class by 
reason of the acts described herein, and whether Williams aided and abetted the 
commission of such breaches.

              (c)  The claims of the plaintiff are typical of the claims of the 
other members of the Class and plaintiff has no interests that are adverse or 
antagonistic to the interests of the Class.

                                     - 3 -

              (d)  Plaintiff is committed to the vigorous prosecution of this 
action and has retained competent counsel experienced in litigation of this 
nature.  Accordingly, plaintiff is an adequate representative of the Class and 
will fairly and adequately protect the interests of the Class.

              (e)  The prosecution of separate actions by individual members of 
the Class would create a risk of inconsistent or varying adjudications with 
respect to individual members of the Class and establish incompatible standards 
of conduct for the party opposing the Class.

              (f)  Defendants have acted and are about to act on grounds 
generally applicable to the Class, thereby making appropriate final injunctive 
or corresponding declaratory relief with respect to the Class as a whole.

                              FACTUAL BACKGROUND
                              ------------------

          8.  On December 12, 1994, Transco and Williams announced that they had
reached a definitive merger agreement pursuant to which Williams will acquire 
60% of the common stock of Transco through a cash tender offer of $17.50 per 
Transco share.  The cash tender offer will be followed by a stock merger in 
which shares of Transco common stock not purchased in the tender offer will be 
exchanged for 0.625 shares of Williams' common stock.  The merger agreement has 
been approved by both Transco's and Williams' board of directors.  The merger 
agreement constitutes a "change of

                                     - 4 -

control" requiring the individual defendants to maximize shareholder value.

          9.  As part of the transaction, Williams and Transco also entered into
a stock option agreement (the "lock-up option") providing for a grant of an 
option to Williams to purchase, at $17.50 per share, up to 7.5 million 
additional shares of Transco common stock.

         10.  As reported by The Value Line Investment Survey, Transco's main 
pipeline subsidiary, Transcontinental Gas Pipeline Corp., is performing well, 
benefitting from a variety of factors including lower operating costs, reduced 
interest expense, and higher allowances on equity.  The Company's gas marketing 
division's results are also improving, for which the net income has risen 
substantially on a year-over-year basis.

         11.  Expansion programs will play a major role in Transco's earnings 
growth over the long haul.  Currently, Transco is engaged in several pipeline
and storage projects that will increase the Company's service areas and 
transportation capacity.  Most of these programs are slated to be in operation 
by 1996.  Finally, Transco's dividend yield is considered above average compared
to its industry peers, and its earnings potential remains strong.

         12.  By virtue of its due diligence negotiations with Transco and the 
merger agreement with the Company, Williams has been privy to material 
nonpublic information

                                     - 5 -

concerning Transco's business and the desirability and value of same.
Accordingly, Williams has positioned itself to purchase the outstanding shares
of Transco at an unreasonably low and unfair price to the detriment of plaintiff
and the other public stockholders of the Company. Such a merger between Transco
and Williams would allow Williams, without paying adequate consideration for
Transco shares, to further strengthen its position in the energy industry.

         13.  The transaction has been structured as a two-step transaction, the
first step being a tender offer for $17.50 per Transco share in cash, and the 
second step being a merger for 0.625 shares of Williams stock per Transco share.
Since Transco shareholders do not know the value of the Williams securities to 
be paid on the "back-end" (particularly since the defendants have failed to 
establish a collar with respect to these securities), they will be coerced into 
tendering their shares on the front end of the offer for inadequate cash 
consideration.

         14.  Because of the announcement of the definitive merger agreement and
the structure of the transaction, no fair market check to determine the fair 
value of Transco's publicly held shares can be conducted.  Moreover, defendants 
have set the price for the publicly held shares of Transco without taking 
adequate steps to determine the fair value of such securities.

                                     - 6 -

         15.  The actions taken by the individual defendants in entering into 
the merger agreement and the lock-up option are in gross disregard of the 
fiduciary duties owed to plaintiff and the other members of the Class, including
their obligation to maximize shareholder value.

         16.  Defendant Williams, without which the proposed transaction would 
not occur, and with knowledge of the individual defendants' breach of fiduciary 
duty, has aided and rendered substantial assistance to the individual defendants
and stands to handsomely profit from the transaction.

         17.  Plaintiff and the other members of the Class will suffer 
irreparable injury unless the unlawful transactions complained of herein are 
enjoined.

         18.  Plaintiff and the Class have no adequate remedy at law.

         WHEREFORE, plaintiff demands judgment and preliminary and permanent 
relief, including injunctive relief, in his favor and in favor of the Class and 
against defendants as follows:

     A.  Declaring that this action is properly maintainable as a class action, 
and certifying plaintiff as class representative;

     B.  Declaring that the individual defendants and each of them have 
committed a gross abuse of trust and have breached their fiduciary duties to 
plaintiff and the other members of the Class;

                                     - 7 -

     C.  Enjoining the tender offer and the merger;

     D.  If the proposed transactions are consummated in whole or in part, 
rescinding the same or awarding rescissory damages to plaintiff and the Class;

     E.  Awarding plaintiff and the Class compensatory damages;

     F.  Awarding plaintiff the costs and disbursements of this action, 
including reasonable attorneys' and experts' fees; and

     G.  Granting such other and further relief as this Court may deem just and 
proper.
