effective at the Effective Time.

            1.8 EFFECT ON CAPITAL STOCK. (a) At the Effective Time, by
virtue of the Merger and without any action on the part of the holder
thereof, each share of Company Common Stock issued and outstanding
immediately prior to the Effective Time (other than shares of Company
Common Stock owned by Parent or Merger Sub or held by the Company, all of
which shall be canceled as provided in Section 1.8(c)), shall be converted
into 1.896 validly issued, fully paid and non-assessable Parent Ordinary
Shares (the "Common Exchange Ratio").

            (b) At the Effective Time, by virtue of the Merger and without
any action on the part of the holder thereof, each share of Company
Preferred Stock issued and outstanding immediately prior to the Effective
Time (other than shares of Company Preferred Stock owned by Parent or

            (c) As a result of the Merger and without any action on the
part of the holders thereof, at the Effective Time, all shares of Company
Common Stock and Company Preferred Stock shall cease to be outstanding and
shall be canceled and retired and shall cease to exist, and each holder of
a certificate which immediately prior to the Effective Time represented any
such shares of Company Common Stock or Company Preferred Stock (each a
"Certificate") shall thereafter cease to have any rights with respect to
such shares of Company Common Stock or Company Preferred Stock, as the case
may be, except as provided herein or by law.

            (d) Each share of Company Common Stock and each share of
Company Preferred Stock issued and owned by Parent or Merger Sub or held by
the Company at the Effective Time shall, by virtue of the Merger, cease to
be outstanding and shall be canceled and retired and no Ordinary Shares of
Parent or other consideration shall be delivered in exchange therefor.

            (e) At the Effective Time, by virtue of the Merger and without
any action on the part of the holder thereof, each share of common stock,
par value $1.00 per share, of Merger Sub issued and outstanding immediately
prior to the Effective Time, shall be converted into one validly issued,
fully paid and non-assessable share of common stock, par value $0.01 per
share, of the Surviving Corporation.

            1.9 CERTAIN ADJUSTMENTS. Other than in connection with the
Acambuco Contribution (as defined in Section 5.13), if, between the date of
this Agreement and the Effective Time, the outstanding Parent Ordinary
Shares, Company Common Stock or Company Preferred Stock shall have been
changed into a different number of shares or different class by reason of
any issuance, reclassification, recapitalization, stock split, split-up,
combination or exchange of shares or a stock dividend or dividend payable
in any other securities shall be declared with a record date within such
period, or any similar event shall have occurred, the Common Exchange Ratio
and the Preferred Exchange Ratio, as the case may be, shall be
appropriately adjusted to provide to the holders of Company Common Stock
and Company Preferred Stock, as the case may be, the same economic effect
as contemplated by this Agreement prior to such event.

            1.10 OPTION RESTRUCTURING. Prior to the Effective Time, the
Company shall take all necessary and desirable action such that immediately
prior to the Effective Time (i) all options, warrants, convertible
securities or other rights to acquire capital stock of the Company shall be
exercised or terminated and accordingly, no options, warrants, convertible
securities or other rights to acquire capital stock of the Company shall be
outstanding (the "Option Restructuring"). Any options, warrants,
convertible securities or other rights to acquire capital stock of the
Company outstanding immediately prior to the Effective Time shall terminate
upon the Effective Time. Schedule 1.10 sets forth a complete and accurate
list, as of the date hereof and as of immediately after the Option
Restructuring (but immediately prior to the Effective Time), of (i) the
stockholders of the Company and the number and class of shares of capital
stock of the Company owned by each such stockholder and (ii) the holders of
options, warrants, convertible securities or other rights to acquire
capital stock of the Company, the exercise price for such options,
warrants, convertible securities or other rights to acquire capital stock
of the Company, the class of capital stock of the Company such options,
warrants, convertible securities or other rights to acquire capital stock
are exercisable into and whether or not such options, warrants, convertible
securities or other rights to acquire capital stock of the Company are
exercisable. The Company has received from each holder of options,
warrants, convertible securities or other rights to acquire capital stock
of the Company an agreement (the "Option Exercise Agreement") that such
holder will exercise such options, warrants, convertible securities or
other rights to acquire capital stock of the Company prior to the Effective
Time and that to the extent such options, warrants, convertible securities
or other rights to acquire capital stock of the Company are not exercised
such options, warrants, convertible securities or other rights to acquire
capital stock of the Company shall terminate and be cancelled upon the
Effective Time. The Company has provided Parent a complete and accurate
copy of each Option Exercise Agreement. The Option Restructuring and all
actions taken in connection with implementing the Option Restructuring
shall be subject to the prior approval of Parent, such approval not to be
unreasonably withheld.

            1.11 DISSENTER'S RIGHTS. Notwithstanding anything in this
Agreement to the contrary, any shares of Company Common Stock or Company
Preferred Stock outstanding immediately prior to the Effective Time and
held by a holder who has not voted in favor of the Merger or consented
thereto in writing and who has delivered a written demand for appraisal of
such shares in accordance with Section 262 of the DGCL, if such Section 262
provides for appraisal rights for such shares in the Merger ("Dissenting
Shares"), shall not be converted into the right to receive the Merger
Consideration, unless and until such holder fails to perfect or effectively
withdraws or otherwise loses his right to appraisal and payment under the
DGCL. If, after the Effective Time, any such holder fails to perfect or
effectively withdraws or loses his right to appraisal, such Dissenting
Shares shall thereupon be treated as if they had been converted as of the
Effective Time into the right to receive the Merger Consideration to which
such holder is entitled, without interest or dividends thereon. Any amounts
paid to holders of Dissenting Shares in an appraisal proceeding will be
paid by the Surviving Corporation out of its own funds and will not be
paid, directly or indirectly, by Parent.


                                 ARTICLE II

                          EXCHANGE OF CERTIFICATES

            2.1 EXCHANGE FUND. Prior to the Effective Time, Parent shall
appoint Bank of New York (or one of its affiliates) to act as exchange
agent hereunder for the purpose of exchanging Certificates for the Merger
Consideration (the "Exchange Agent"). At or prior to the Effective Time,
Parent shall deposit with the Exchange Agent, in trust for the benefit of
holders of shares of Company Common Stock and Company Preferred Stock,
certificates representing the Parent Ordinary Shares issuable pursuant to
Section 1.8 in exchange for outstanding shares of Company Common Stock and
Company Preferred Stock. Parent agrees to make available to the Exchange
Agent from time to time as needed, cash sufficient to pay cash in lieu of
fractional shares pursuant to Section 2.5 and any dividends and other
distributions pursuant to Section 2.3. Any cash and certificates of Parent
Ordinary Shares deposited with the Exchange Agent shall hereinafter be
referred to as the "Exchange Fund."

            2.2 EXCHANGE PROCEDURES. Promptly after the Effective Time, the
Surviving Corporation shall cause the Exchange Agent to mail to each holder
of a Certificate (i) a letter of transmittal which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates
shall pass, only upon proper delivery of the Certificates to the Exchange
Agent, and which letter shall be in customary form and have such other
provisions as Parent may reasonably specify (such letter to be reasonably
acceptable to the Company prior to the Effective Time) and (ii)
instructions for effecting the surrender of such Certificates in exchange
for the applicable Merger Consideration. Upon surrender of a Certificate to
the Exchange Agent together with such letter of transmittal, duly executed
and completed in accordance with the instructions thereto, and such other
documents as may reasonably be required by the Exchange Agent, the holder
of such Certificate shall be entitled to receive in exchange therefor (A)
one or more Parent Ordinary Shares (which shall be in uncertificated
book-entry form unless a physical certificate is requested) representing,
in the aggregate, the whole number of shares that such holder has the right
to receive pursuant to Section 1.8 (after taking into account all shares of
Company Common Stock and Company Preferred Stock then held by such holder)
and (B) a check in the amount equal to the cash that such holder has the
right to receive pursuant to the provisions of this Article II, including
cash in lieu of any fractional Parent Ordinary Shares pursuant to Section
2.5 and dividends and other distributions pursuant to Section 2.3. No
interest will be paid or will accrue on any cash payable pursuant to
Section 2.3 or Section 2.5. 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, one or more Parent Ordinary Shares
evidencing, in the aggregate, the proper number of Parent Ordinary Shares,
a check in the proper amount of cash in lieu of any fractional Parent
Ordinary Shares pursuant to Section 2.5 and any dividends or other
distributions to which such holder is entitled pursuant to Section 2.3, may
be issued with respect to such Company Common Stock or Company Preferred
Stock to such a transferee if the Certificate representing such shares of
Company Common Stock or Company Preferred Stock is presented to the
Exchange Agent, accompanied by all documents required to evidence and
effect such transfer and to evidence that any applicable stock transfer
taxes have been paid.

            2.3 DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES. No
dividends or other distributions declared or made with respect to Parent
Ordinary Shares with a record date after the Effective Time shall be paid
to the holder of any unsurrendered Certificate with respect to the Parent
Ordinary Shares that such holder would be entitled to receive upon
surrender of such Certificate and no cash payment in lieu of fractional
Parent Ordinary Shares shall be paid to any such holder pursuant to Section
2.5 until such holder shall surrender such Certificate in accordance with
Section 2.2. Subject to the effect of applicable laws, following surrender
of any such Certificate, there shall be paid to such holder of Parent
Ordinary Shares issuable in exchange therefor, without interest, (a)
promptly after the time of such surrender, the amount of any cash payable
in lieu of fractional Parent Ordinary Shares to which such holder is
entitled pursuant to Section 2.5 and the amount of dividends or other
distributions with a record date after the Effective Time theretofore paid
with respect to such whole Parent Ordinary Shares, and (b) at the
appropriate payment date, the amount of dividends or other distributions
with a record date after the Effective Time but prior to such surrender and
a payment date subsequent to such surrender payable with respect to such
Parent Ordinary Shares.

            2.4 NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK OR
COMPANY PREFERRED STOCK. All Parent Ordinary Shares issued and cash paid
upon conversion of shares of Company Common Stock and Company Preferred
Stock in accordance with the terms of Article I and this Article II
(including any cash paid pursuant to Section 2.3 or 2.5) shall be deemed to
have been issued or paid in full satisfaction of all rights pertaining to
the shares of Company Common Stock and Company Preferred Stock.

            2.5 NO FRACTIONAL PARENT ORDINARY SHARES. (a) No certificates
or scrip or Parent Ordinary Shares representing fractional Parent Ordinary
Shares or book-entry credit of the same shall be issued upon the surrender
for exchange of Certificates and such fractional share interests will not
entitle the owner thereof to vote or to have any rights of a shareholder of
Parent or a holder of Parent Ordinary Shares.

            (b) Notwithstanding any other provision of this Agreement, each
holder of shares of Company Common Stock and Company Preferred Stock
exchanged pursuant to the Merger who would otherwise have been entitled to
receive a fraction of a Parent Ordinary Share (after taking into account
all Certificates delivered by such holder) shall receive, in lieu thereof,
cash (without interest) in an amount equal to the product of (i) such
fractional part of a Parent Ordinary Share multiplied by (ii) the closing
price for a Parent Ordinary Share on the National Association of Securities
Dealers Automated Quotation System ("NASDAQ") on the date of the Effective
Time or, if such date is not a Business Day, the Business Day immediately
following the date on which the Effective Time occurs.

            (c) As promptly as practicable after the determination of the
amount of cash, if any, to be paid to holders of fractional interests, the
Exchange Agent shall so notify Parent, and Parent shall cause the Surviving
Corporation to deposit such amount with the Exchange Agent and shall cause
the Exchange Agent to forward payments to such holders of fractional
interests subject to and in accordance with the terms hereof.

            2.6 TERMINATION OF EXCHANGE FUND. Any portion of the Exchange
Fund which remains undistributed to the holders of Certificates for six
months after the Effective Time shall be delivered to Parent or otherwise
on the instruction of Parent, and any holders of the Certificates who have
not theretofore complied with this Article II shall thereafter look only to
Parent for the Merger Consideration with respect to the shares of Company
Common Stock and Company Preferred Stock formerly represented thereby to
which such holders are entitled pursuant to Section 1.8 and Section 2.2,
any cash in lieu of fractional Parent Ordinary Shares to which such holders
are entitled pursuant to Section 2.5 and any dividends or distributions
with respect to Parent Ordinary Shares to which such holders are entitled
pursuant to Section 2.3. Any such portion of the Exchange Fund remaining
unclaimed by holders of shares of Company Common Stock and Company
Preferred Stock five years after the Effective Time (or such earlier date
immediately prior to such time as such amounts would otherwise escheat to
or become property of any Governmental Entity (as defined in Section
3.1(c)(iii)) shall, to the extent permitted by law, become the property of
the Surviving Corporation free and clear of any claims or interest of any
Person previously entitled thereto.

            2.7 NO LIABILITY. None of Parent, Merger Sub, the Company, the
Surviving Corporation or the Exchange Agent shall be liable to any Person
in respect of any Merger Consideration from the Exchange Fund delivered to
a public official pursuant to any applicable abandoned property, escheat or
similar law.

            2.8 INVESTMENT OF THE EXCHANGE FUND. The Exchange Agent shall
invest any cash included in the Exchange Fund as directed by Parent on a
daily basis; provided, that no such gain or loss thereon shall affect the
amounts payable to the Company stockholders pursuant to Article I and the
other provisions of this Article II. Any interest and other income
resulting from such investments shall promptly be paid to Parent.

            2.9 LOST CERTIFICATES. If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the
Person claiming such Certificate to be lost, stolen or destroyed and, if
required by the Surviving Corporation, the posting by such Person of a bond
in such reasonable amount as the Surviving Corporation may direct as
indemnity against any claim that may be made against it with respect to
such Certificate, the Exchange Agent will deliver in exchange for such
lost, stolen or destroyed Certificate the applicable Merger Consideration
with respect to the shares of Company Common Stock and Company Preferred
Stock formerly represented thereby, any cash in lieu of fractional Parent
Ordinary Shares, and unpaid dividends and distributions on Parent Ordinary
Shares deliverable in respect thereof, pursuant to this Agreement.

            2.10 WITHHOLDING RIGHTS. Each of the Surviving Corporation and
Parent shall be entitled to deduct and withhold from the consideration
otherwise payable pursuant to this Agreement to any holder of shares of
Company Common Stock or Company Preferred Stock such amounts as it is
required to deduct and withhold with respect to the making of such payment
under the Code and the rules and regulations promulgated thereunder, or any
provision of state, local or foreign tax law. To the extent that amounts
are so withheld by the Surviving Corporation or Parent, as the case may be,
such withheld amounts shall 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 the Surviving Corporation or Parent, as the case may be.

            2.11 FURTHER ASSURANCES. At and after the Effective Time, the
officers and directors of the Surviving Corporation will be authorized to
execute and deliver, in the name and on behalf of the Company or Merger
Sub, any deeds, bills of sale, assignments or assurances and to take and
do, in the name and on behalf of the Company or Merger Sub, any other
actions and things to vest, perfect or confirm of record or otherwise in
the Surviving Corporation any and all right, title and interest in, to and
under any of the rights, properties or assets acquired or to be acquired by
the Surviving Corporation as a result of, or in connection with, the
Merger.

            2.12 STOCK TRANSFER BOOKS. The stock transfer books of the
Company shall be closed immediately upon the Effective Time and there shall
be no further registration of transfers of shares of Company Common Stock
or Company Preferred Stock thereafter on the records of the Company. On or
after the Effective Time, any Certificates presented to the Exchange Agent
or Parent for any reason shall be converted into the Merger Consideration
with respect to the shares of Company Common Stock or Company Preferred
Stock formerly represented thereby (including any cash in lieu of
fractional Parent Ordinary Shares to which the holders thereof are entitled
pursuant to Section 2.5) and any dividends or other distributions to which
the holders thereof are entitled pursuant to Section 2.3.


                                ARTICLE III

                       REPRESENTATIONS AND WARRANTIES

            3.1 REPRESENTATIONS AND WARRANTIES OF PARENT. Except as set
forth in the Parent disclosure schedule delivered by Parent to the Company
prior to the execution of this Agreement (the "Parent Disclosure Schedule")
(each section of which qualifies the correspondingly numbered
representation and warranty or covenant), Parent represents and warrants to
the Company as follows:

            (a)   Organization, Standing and Power; Subsidiaries.

            (i) Each of Parent and its Subsidiaries (as defined in Section
      8.11) is duly organized, validly existing and in good standing under
      the laws of its jurisdiction of organization, has the requisite power
      and authority to own, lease and operate its properties and to carry
      on its business as now being conducted, except where the failures to
      be so organized, existing and in good standing or to have such power
      and authority, individually or in the aggregate, would not reasonably
      be expected to have a Material Adverse Effect on Parent, and is duly
      qualified and in good standing to do business in each jurisdiction in
      which the nature of its business or the ownership or leasing of its
      properties makes such qualification necessary other than in such
      jurisdictions where the failures so to qualify or to be in good
      standing, individually or in the aggregate, would not reasonably be
      expected to have a Material Adverse Effect on Parent. The copies of
      the Memorandum of Association and Articles of Association of Parent
      which were previously furnished or made available to the Company are
      true, complete and correct copies of such documents as in effect on
      the date of this Agreement.

            (ii) The Parent Disclosure Schedule sets forth a complete and
      accurate list of Parent's Subsidiaries. All the outstanding shares of
      capital stock of, or other equity interests in, each such Subsidiary
      have been validly issued and are fully paid and non-assessable and
      are, except as set forth in the Parent Disclosure Schedule, owned
      directly or indirectly by Parent, free and clear of all pledges,
      claims, liens, charges, encumbrances and security interests of any
      kind or nature whatsoever (collectively "Liens") and free of any
      other restriction (including any restriction on the right to vote,
      sell or otherwise dispose of such capital stock or other ownership
      interests), except for restrictions imposed by applicable securities
      laws. Except as set forth in the Parent SEC Reports (as defined in
      Section 3.1(d)) filed prior to the date hereof or in the Parent
      Disclosure Schedule, neither Parent nor any of its Subsidiaries
      directly or indirectly owns any equity or similar interest in, or any
      interest convertible into or exchangeable or exercisable for, any
      corporation, partnership, joint venture or other business association
      or entity (other than Subsidiaries), that is or would reasonably be
      expected to be material to Parent.

            (b)   Capital Structure.

            (i) As of the date hereof, the authorized capital stock of
      Parent consisted of 15,000,000 Parent Ordinary Shares of which
      7,360,311 shares were issued and outstanding and no shares were held
      in the treasury of Parent. All issued and outstanding shares of the
      capital stock of Parent are, and when Parent Ordinary Shares are
      issued in the Merger will be, duly authorized, validly issued, fully
      paid and non-assessable and free of any preemptive rights. As of the
      date hereof, there are no outstanding options, warrants convertible
      securities or other rights to acquire capital stock of Parent. The
      Parent Disclosure Schedule sets forth a complete and accurate list of
      each Subsidiary of the Parent and the number of authorized, issued
      and outstanding shares of capital stock of each of such Subsidiary.

            (ii) No bonds, debentures, notes or other indebtedness of
      Parent having the right to vote on any matters on which holders of
      capital stock of Parent may vote are issued or outstanding.

            (iii) As of the date of this Agreement, there are no
      securities, options, warrants, calls, rights, commitments,
      agreements, arrangements or undertakings of any kind to which Parent
      or any of its Subsidiaries is a party or by which any of them is
      bound obligating Parent or any of its Subsidiaries to issue, deliver
      or sell, or cause to be issued, delivered or sold, shares of capital
      stock or other voting securities of Parent or any of its Subsidiaries
      or obligating Parent or any of its Subsidiaries to issue, grant,
      extend or enter into any such security, option, warrant, call, right,
      commitment, agreement, arrangement or undertaking. As of the date of
      this Agreement, there are no outstanding obligations of Parent or any
      of its Subsidiaries to repurchase, redeem or otherwise acquire any
      shares of capital stock of Parent or any of its Subsidiaries.

            (c)   Authority; No Conflicts.

            (i) Parent has all requisite corporate power and authority to
      enter into this Agreement and to consummate the transactions
      contemplated hereby, subject to obtaining the requisite stockholder
      approval of: (i) the issuance of the Parent Ordinary Shares to be
      issued in the Merger (the "Share Issuance"), (ii) the Memorandum
      Amendment, and (iii) the Articles Amendment (collectively, the
      "Parent Stockholder Approval"). The execution and delivery of this
      Agreement and the consummation of the transactions contemplated
      hereby have been duly authorized by all necessary corporate action on
      the part of Parent, subject to obtaining the Parent Shareholder
      Approval. This Agreement has been duly executed and delivered by
      Parent and constitutes a valid and binding agreement of Parent,
      enforceable against it in accordance with its terms, except as such
      enforceability may be limited by bankruptcy, insolvency,
      reorganization, moratorium and similar laws relating to or affecting
      creditors generally or by general equity principles (regardless of
      whether such enforceability is considered in a proceeding in equity
      or at law).

            (ii) The execution and delivery of this Agreement by Parent
      does not, and the consummation by Parent of the Merger and the other
      transactions contemplated hereby will not, conflict with, or result
      in any violation of, or constitute a default (with or without notice
      or lapse of time, or both) under, or give rise to a right of, or
      result by its terms in the, termination, amendment, cancellation or
      acceleration of any obligation or the loss of a material benefit
      under, or the creation of a lien, pledge, security interest, charge
      or other encumbrance on, or the loss of, any assets (any such
      conflict, violation, default, right of termination, amendment,
      cancellation or acceleration, loss or creation, a "Violation")
      pursuant to: (A) any provision of the Memorandum of Association and
      Articles of Association of Parent or any similar governing documents
      of any material Subsidiary of Parent, or (B) except as, individually
      or in the aggregate, would not reasonably be expected to have a
      Material Adverse Effect on Parent, any loan or credit agreement,
      note, mortgage, bond, indenture, lease, benefit plan or other
      agreement, obligation, instrument, permit, concession, franchise,
      license, judgment, order, decree, statute, law, ordinance, rule or
      regulation applicable to Parent or any Subsidiary of Parent or their
      respective properties or assets.

            (iii) No consent, approval, order or authorization of, or
      registration, declaration or filing with, any supranational,
      national, state, municipal, local or foreign government, any
      instrumentality, subdivision, court, administrative agency or
      commission or other authority thereof, or any quasi-governmental or
      private body exercising any regulatory, taxing, importing or other
      governmental or quasi-governmental authority (a "Governmental
      Entity"), is required by or with respect to Parent or any Subsidiary
      of Parent in connection with the execution and delivery of this
      Agreement by Parent or the consummation of the Merger and the other
      transactions contemplated hereby, except for those required under or
      in relation to (A) state securities or "blue sky" laws (the "Blue Sky
      Laws"), (B) the Securities Act, (C) the Exchange Act, (D) the DGCL
      with respect to the filing of the Certificate of Merger, (E) rules
      and regulations of NASDAQ, (F) antitrust or other competition laws of
      jurisdictions other than the United States, and (G) such consents,
      approvals, orders, authorizations, registrations, declarations and
      filings the failures of which to make or obtain, individually or in
      the aggregate, would not reasonably be expected to have a Material
      Adverse Effect on Parent. Consents, approvals, orders,
      authorizations, registrations, declarations and filings required
      under or in relation to any of the foregoing clauses (A) through (F)
      are hereinafter referred to as "Necessary Consents."

            (d)   Reports and Financial Statements.

            (i) Parent has filed all required registration statements,
      prospectuses, reports, schedules, forms, statements and other
      documents required to be filed by it with the Securities Exchange
      Commission (the "SEC") since January 1, 1996 (collectively, including
      all exhibits thereto, the "Parent SEC Reports"). None of the Parent
      SEC Reports, as of their respective dates (and, if amended or
      superseded by a filing prior to the date of this Agreement or the
      Closing Date, then on the date of such filing), contained or will
      contain any untrue statement of a material fact or omitted or will
      omit to state a material fact required to be stated therein or
      necessary to make the statements therein, in light of the
      circumstances under which they were made, not misleading. Each of the
      financial statements (including the related notes) included in the
      Parent SEC Reports presents fairly, in all material respects, the
      consolidated financial position and consolidated results of
      operations and cash flows of Parent and its consolidated Subsidiaries
      as of the respective dates or for the respective periods set forth
      therein, all in conformity with United States generally accepted
      accounting principles ("GAAP") consistently applied during the
      periods involved except as otherwise noted therein, and subject, in
      the case of the unaudited interim financial statements, to the
      absence of notes and normal year-end adjustments that have not been
      and are not expected to be material in amount.

            (ii) Except as disclosed in the Parent SEC Reports filed prior
      to the date hereof, since December 31, 2000, Parent and its
      Subsidiaries have not incurred any liabilities that are of a nature
      that would be required to be disclosed on a balance sheet of Parent
      and its Subsidiaries or the footnotes thereto prepared in conformity
      with GAAP, other than (A) liabilities incurred in the ordinary course
      of business or (B) liabilities that, individually or in the
      aggregate, would not reasonably be expected to have a Material
      Adverse Effect on Parent.

            (e)   Information Supplied.

            (i) None of the information supplied or to be supplied by
      Parent for inclusion or incorporation by reference in (A) the Form
      S-4 (as defined in Section 5.1) will, at the time the Form S-4 is
      filed with the SEC, at any time it is amended or supplemented or at
      the time it becomes effective under the Securities Act, contain any
      untrue statement of a material fact or omit to state any material
      fact required to be stated therein or necessary to make the
      statements therein not misleading and (B) the Joint Proxy
      Statement/Prospectus (as defined in Section 5.1) will, on the date it
      is first mailed to Company stockholders or Parent shareholders or at
      the time of the Company Stockholders Meeting or the Parent
      Shareholders Meeting (each as defined in Section 5.1), contain any
      untrue statement of a material fact or omit to state any material
      fact required to be stated therein or necessary in order to make the
      statements therein, in light of the circumstances under which they
      were made, not misleading. The Form S-4 and the Joint Proxy
      Statement/Prospectus will comply as to form in all material respects
      with the requirements of the Exchange Act and the Securities Act and
      the rules and regulations of the SEC thereunder.

            (ii) Notwithstanding the foregoing provisions of this Section
      3.1(e), no representation or warranty is made by Parent with respect
      to statements made or incorporated by reference in the Form S-4 or
      the Joint Proxy Statement/Prospectus based on information supplied by
      the Company for inclusion or incorporation by reference therein.

            (f) Board Approval. The Board of Directors of Parent, by
resolutions duly adopted by unanimous vote at a meeting duly called and
held and not subsequently rescinded or modified in any way (the "Parent
Board Approval"), has duly (i) determined that this Agreement and the
Merger are advisable and are fair to and in the best interests of Parent
and its shareholders, (ii) approved this Agreement, the Merger, the
Memorandum Amendment, the Articles Amendment and the Share Issuance and
(iii) recommended that the shareholders of Parent approve the Share
Issuance, the Memorandum Amendment and the Articles Amendment and directed
that the Share Issuance, the Memorandum Amendment and the Articles
Amendment be submitted for consideration by Parent's shareholders at the
Parent Shareholders Meeting.

            (g) Vote Required. The affirmative vote by a majority of the
votes cast by holders of Parent Ordinary Shares is the only vote necessary
to approve the Share Issuance. The only votes necessary to approve the
Memorandum Amendment are an affirmative vote by special resolution of at
least two-thirds of the votes cast by the holders of Parent Ordinary Shares
at a general meeting. The affirmative vote by special resolution of at
least two-thirds of the votes cast by the holders of Parent Ordinary Shares
at a general meeting is the only vote necessary to approve the Articles
Amendment.

      (collectively "Actions") pending or, to the knowledge of Parent,
      threatened, against or affecting Parent or any Subsidiary of Parent,
      nor are there any judgments, decrees, injunctions, rules or orders of

      Schedule, neither Parent nor any of its Subsidiaries is in violation
      of, and Parent and its Subsidiaries have not received any notices of
      violations with respect to, any laws, ordinances or regulations of
      any Governmental Entity, except for violations which, individually or
      in the aggregate, would not reasonably be expected to have a Material
      Adverse Effect on Parent.

            (i) Absence of Certain Changes or Events. Except for

conducted their business only in the ordinary course and (ii) there has not
been any action taken by Parent or its Subsidiaries during the period from
December 31, 2000 through the date of this Agreement that, if taken during
the period from the date of this Agreement through the Effective Time,
would constitute a breach of Section 4.1. Except as disclosed in Parent SEC
Documents or as set forth in the Parent Disclosure Schedule, since December
31, 2000 there have not been any changes, circumstances, or events which
individually or in the aggregate have had, or would reasonably be expected
to have a Material Adverse Effect on the Parent.

            (j) Environmental Matters. Except as set forth in the Parent

      valid and binding obligation of Parent or its Subsidiaries, as the
      case may be, enforceable in accordance with its terms and will
      continue to be so on identical terms immediately following the
      consummation of the transactions contemplated by this Agreement, and
      Parent or its Subsidiaries, as the case may be, are not in default
      under any of such agreements, nor has any event or circumstance
      occurred that, with notice or lapse of time or both, would constitute
      any event of default by Parent or its Subsidiaries, as the case may
      be. No other party to any of the Parent Material Agreements (A) is,

in each case, that is sponsored, maintained or contributed to or required
to be contributed to by Parent or by any trade or business, whether or not
incorporated (a "Parent ERISA Affiliate"), that, together with Parent would
be deemed a "single employer" within the meaning of Section 4001(b) of
ERISA, or to which Parent or a Parent ERISA Affiliate is party, whether
written or oral, for the benefit of any employee or director or former
employee or director (or any of their respective beneficiaries), of Parent
or any of its Subsidiaries (the "Parent Benefit Plans").

                  (ii) With respect to each Parent Benefit Plan, Parent has
heretofore delivered or made available to the Company true and complete

satisfied in full, and no condition exists that presents a material risk to
Parent or any ERISA Affiliate of incurring any such liability, other than
liability for premiums due the Pension Benefit Guaranty Corporation
("PBGC") (which premiums have been paid when due).

                  (iv) No Parent Benefit Plan has, to the knowledge of
Parent, engaged in a "prohibited transaction" (as defined in Section 4975
of the Code or Section 406 of ERISA).

                  (v) With respect to each Parent Benefit Plan subject to
Title IV of ERISA (the "Title IV Parent Benefit Plans"), the present value
of accrued benefits under such plan, based upon the actuarial assumptions
used for funding purposes in the most recent actuarial report prepared by
such plan's actuary with respect to such plan did not exceed, as of its
latest valuation date, the then current value of the assets of such plan
allocable to such accrued benefits.

                  (vi) No Title IV Parent Benefit Plan or any trust
established thereunder has incurred any "accumulated funding deficiency"
(as defined in Section 302 of ERISA and Section 412 of the Code), whether

Title IV Parent Benefit Plan ended prior to the Closing Date nor has there

applicable law, including but not limited to ERISA and the Code, the rules
and regulations thereunder and all applicable collective bargaining
agreements and each Parent Benefit Plan intended to be "qualified" under
Section 401(a) of the Code has received a favorable determination letter
from the Internal Revenue Service to such effect. To the knowledge of
Parent, there is no fact, condition or set of circumstances existing that
could adversely affect such favorable determination. To the knowledge of
Parent, there are no investigations pending in respect of any Parent
Benefit Plan by any governmental entity.

                  (ix) No Parent Benefit Plan provides medical, surgical,
hospitalization, death or similar benefits (whether or not insured) for
employees or former employees (or their beneficiaries) of Parent or any of
its Subsidiaries for periods extending beyond their respective dates of
retirement or other termination of service, other than (A) coverage
mandated by applicable law, (B) death benefits under any "pension plan" or
(C) benefits the full cost of which is borne by the current or former
employee (or his beneficiary).

                  (x) Except as set forth in the Parent Disclosure
Schedule, no amounts payable or that could become payable under the Parent
Benefit Plans may fail to be deductible for Federal income tax purposes by
virtue of either Section 280G or 162(m) of the Code.

                  (xi) Except as set forth in the Parent Disclosure
Schedule, the consummation of the transactions contemplated by this
Agreement will not, either alone or in combination with another event, (A)
entitle any current or former employee, director or officer of Parent or
any of its Subsidiaries to severance pay, unemployment compensation or any
other payment, (B) accelerate the time of payment or vesting, or increase
the amount of compensation due any such employee, director or officer or
(C) require the immediate funding or financing of any compensation or
benefits.

                  (xii) Each Parent Benefit Plan that has been adopted or
maintained by Parent or any of its Subsidiaries, whether formally or
informally, for the benefit of employees of Parent or any of its
Subsidiaries outside of the United States (a "Parent Foreign Benefit Plan")
has been established, maintained and administered in material compliance
with its terms and conditions and with the requirements prescribed by any
and all regulatory laws that are applicable to such Parent Foreign Benefit
Plan. No Parent Foreign Benefit Plan has unfunded liabilities that,
individually or in the aggregate, would reasonably be expected to have a
Material Adverse Affect on Parent.

                  (xiii)There are no pending, threatened or anticipated
claims by or on behalf of any Parent Benefit Plan, by any employee or
beneficiary covered under any such Parent Benefit Plan, or otherwise
involving any such Parent Benefit Plan (other than routine claims for
benefits).

            (q) Labor Matters. Parent has complied, in all material
respects, with all applicable laws of the United States, or of any state or
local government or any subdivision thereof or of any foreign government
respecting employment and employment practices, terms and conditions of

Reform and Control Act, the Worker Adjustment and Retraining Notification
Act (the "WARN Act"), any laws respecting employment discrimination, sexual

Subsidiaries has Defensible Title to all of its Oil and Gas Interests.
Except as set forth in the Parent SEC Reports or the Parent Disclosure
Schedule, each Oil and Gas Interest included or reflected in the Parent
Ownership Interests entitles Parent to receive, directly or indirectly, not
less than the undivided interest set forth in (or derived from) the Parent
Ownership Interests of all Hydrocarbons produced, saved and sold from or
attributable to such Oil and Gas Interest, and the portion of the costs and
expenses of operation and development of such Parent Oil and Gas Interest
that is borne or to be borne, directly or indirectly, by Parent is not
greater than the undivided interest set forth in (or derived from) the
Parent Ownership Interests. Except for Permitted Encumbrances, Parent and
each of its Subsidiaries has Defensible Title to its material assets (other
than the Oil and Gas Interests of Parent). All leases pursuant to which
Parent or its Subsidiaries lease any material assets are in full force and
effect, and Parent has not received any notice of default under any such
lease. The Parent Disclosure Schedule sets forth a complete and accurate
list of all material real property, other than Oil and Gas Interests, that
is owned or leased by Parent or its Subsidiaries.

            (s) Parent Engineering Report. All information supplied to the
engineering firm preparing the applicable report by or on behalf of Parent
that was material to the evaluation of Parent's Oil and Gas Interests in
connection with the preparation of the Parent Engineering Report was (at
the time supplied or as modified or amended prior to the issuance of the
Parent Engineering Report) true and correct in all material respects.
Except for changes in classification or values of oil and gas reserves or
property interests that occurred in the ordinary course of business since
December 31, 1999 and except for changes (including changes in commodity
prices) generally affecting the oil and gas industry, there has been no
material adverse change with respect to the matters addressed in the Parent

      fact or omit to state any material fact required to be stated therein
      or necessary to make the statements therein not misleading, and (B)
      the Joint Proxy Statement/Prospectus will, on the date it is first

Title IV of ERISA (the "Title IV Company Benefit Plans"), the present value
of accrued benefits under such plan, based upon the actuarial assumptions
used for funding purposes in the most recent actuarial report prepared by

latest valuation date, the then current value of the assets of such plan

of retirement or other termination of service, other than (A) coverage
mandated by applicable law, (B) death benefits under any "pension plan" or

Plan") has been established, maintained and administered in material
compliance with its terms and conditions and with the requirements
prescribed by any and all regulatory laws that are applicable to such
Company Foreign Benefit Plan. No Company Foreign Benefit Plan has unfunded
liabilities that, individually or in the aggregate, would reasonably be
expected to have a Material Adverse Affect on the Company.

                  (xiii)There are no pending, threatened or anticipated
claims by or on behalf of any Company Benefit Plan, by any employee or
beneficiary covered under any such Company Benefit Plan, or otherwise
involving any such Company Benefit Plan (other than routine claims for

Proxy Statement/Prospectus so that any of such documents would not include
any misstatement of a material fact or omit to state any material fact
necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading, the party which discovers such
information shall promptly notify the other party hereto and, to the extent
required by law, rules or regulations, an appropriate amendment or
supplement describing such information shall be promptly filed with the SEC
and disseminated to the stockholders of Parent and the Company.

lawful action to solicit the approval of the Share Issuance, the Memorandum
Amendment and the Articles Amendment and the Board of Directors of Parent

hereto, by action taken or authorized by their respective Boards of
Directors, at any time before or after approval of the matters presented in

            8.5 ENTIRE AGREEMENT; NO THIRD PARTY BENEFICIARIES. (a) This

("CEO") of the Company. The number of directors on the Search Committee
shall be two, one of whom shall be a person designated by W-CO and the

within its control to cause the Board of Directors to elect C. John Miller
as non-executive Chairman of the Board of Directors of the Company. In the
event that C. John Miller shall for any reason cease to serve as
non-executive Chairman of the Board of Directors, the Board of Directors
shall nominate and elect a new Chairman of the Board of Directors to
replace him.

        (e) Until the New CEO is appointed by the Board of Directors C.
John Miller and a person designated by W-CO shall act as interim co-CEO's
of the Company reporting directly to the entire Board of Directors. In the
event that C. John Miller shall for any reason cease to serve as interim
co-CEO, the resulting vacancy shall be filled by an individual designated
by the G-CO Group. In the event that the person designated by W-CO shall
for any reason cease to serve as interim co-CEO, the resulting vacancy
shall be filled by an individual designated by W-CO.

        (f) As promptly as practicable after being appointed by the Board
of Directors, the New CEO, C. John Miller and a person designated by W-CO
shall conduct a search for a qualified Chief Financial Officer (the "CFO")
of the Company and shall recommend to the entire Board of Directors
potential qualified candidates for CFO of the Company. The Board of
Directors shall appoint, by a vote of a majority of the entire Board of
Directors, a new CFO of the Company from among the candidates recommended
by the New CEO, C. John Miller and the person designated by W-CO.

        3.  SHELF REGISTRATION.

        If the Company at any time during the Registration Period is
eligible to use Form S-3 and then for so long as the Company is so
eligible, the Company shall be subject to the provisions of this Section 3
as follows:

        (a) The Company shall prepare and, not later than 60 days prior to
expiration of the Lockup Period, shall file with the SEC, and thereafter
shall use its commercially reasonable efforts to cause to be declared
effective under the Securities Act on or prior to expiration of the Lockup
Period, a Shelf Registration Statement relating to the offer and sale by
W-CO and the Shareholders comprising the G-CO Group of all Registrable
Securities permitted to be registered on Form S-3 as part of such Shelf
Registration Statement in a manner selected by W-CO and the G-CO
Representative and set forth in such Shelf Registration Statement. No
securities other than Registrable Securities shall be included in any such
initial Shelf Registration Statement or any additional Shelf Registration
Statement with respect thereto without the consent of W-CO and the G-CO
Representative, which consent shall not be unreasonably withheld.

        (b) The Company shall use commercially reasonable efforts to keep
the Shelf Registration Statement continuously effective during the
Registration Period.

        (c) Subject to Section 8 hereof, if the Shelf Registration
Statement ceases to be effective for any reason at any time during the
Registration Period, the Company shall use its commercially reasonable
efforts to obtain the prompt withdrawal of any order suspending the
effectiveness thereof, and shall (i) within 60 days of such cessation of
effectiveness, amend the Shelf Registration Statement in a manner
reasonably expected to obtain the withdrawal of the order suspending the
effectiveness thereof, or (ii) file an additional Shelf Registration
Statement subsequent to the expired or ineffective Shelf Registration
Statement covering the Registrable Securities. If any additional Shelf
Registration Statement is filed, the Company shall use its commercially
reasonable efforts to cause such Shelf Registration Statement to be
declared effective as soon as practicable after such filing and to keep
such Shelf Registration Statement continuously effective for the remainder
of the Registration Period.

        (d) Subject to Section 8 hereof, the Company shall supplement and
amend any Shelf Registration Statement if (i) required by the SEC or the
rules, regulations or instructions applicable to such Shelf Registration
Statement, (ii) otherwise required by the Securities Act or (iii)
reasonably requested by W-CO, the G-CO Representative (on behalf of
Shareholders comprising the G-CO Group) or by the managing underwriters
with respect to an underwritten offering of such Registrable Securities.

        (e) As soon as practicable after determining that Registrable
Securities permitted to be included on Form S-3 in a Shelf Registration
Statement have not been so included, the Company shall file a subsequent
Shelf Registration Statement covering all such unregistered Registrable
Securities that includes a combined Prospectus permitting the inclusion in
such Prospectus of all Registrable Securities eligible to be sold
thereunder, including Registrable Securities included in a previously filed
Registration Statement, provided that no such subsequent Shelf Registration
Statement need be filed for Registrable Securities representing less than
5% of the then outstanding Ordinary Shares unless W-CO or the G-CO
Representative inform the Company that W-CO or the Shareholders comprising
the G-CO Group currently intend to sell such Registrable Securities.

        (f) If at any time or from time to time W-CO or the Shareholders
comprising the G-CO Group desire to sell Registrable Securities in an
underwritten offering pursuant to a Shelf Registration Statement, the
managing underwriters shall be selected by W-CO and the G-CO
Representative; provided that such managing underwriters shall be
nationally recognized investment banking firms and shall be reasonably
satisfactory to the Company.

        4.  DEMAND REGISTRATIONS.

        If at any time during the Registration Period the Company is not
eligible to use Form S-3 then so long as the Company is not so eligible the
Company shall be subject to the provisions of this Section 4 as follows:

        (a) Right to Request Registration. Any time after the expiration of
the Lockup Period (as defined in Section 13), W-CO or the G-CO
Representative (on behalf of the Shareholders comprising the G-CO Group)
(each an "Initiating Holder") may request registration under the Securities
Act of all or part of a number of shares of Registrable Securities
representing at least 1,500,000 (such number to be appropriately adjusted
to reflect stock splits, reverse stock splits, stock dividends,
reclassifications, recapitalizations and similar transactions) shares of
Registrable Securities (any such registration pursuant to this Section 4(a)
referred to herein as a "Demand Registration").

        Within 10 days after receipt of any such request for Demand
Registration, the Company shall give written notice of such request to all
other Holders of Registrable Securities and shall, subject to the
provisions of Section 4(c) hereof, include in such registration all such
Registrable Securities with respect to which the Company has received
written requests for inclusion therein within 15 days after the receipt of
the Company's notice.

        (b) Number of Demand Registrations. Subject to the provisions of
Section 4(a), W-CO and the G-CO Group shall each be entitled to request two
(2) Demand Registrations. A registration shall not count as one of the
permitted Demand Registrations (i) until it has become effective, (ii) if
the Initiating Holder requesting such registration is not able to register
and sell at least 50% of the Registrable Securities requested by such
Initiating Holder to be included in such registration or (iii) in the case
of a Demand Registration that would be the last permitted Demand
Registration requested hereunder, if the Initiating Holder requesting such
registration is not able to register and sell all of the Registrable
Securities requested to be included by such Initiating Holder in such
registration.

        (c) Priority on Demand Registrations. The Company shall not include
in any Demand Registration any securities which are not Registrable
Securities without the written consent of the Holders of a majority of the
shares of Registrable Securities to be included in such registration, and,
if such Demand Registration is an underwritten offering, without the
written consent of the managing underwriters, such consents not to be
unreasonably withheld. If the managing underwriters of the requested Demand
Registration advise the Company in writing that in their opinion the number
of shares of Registrable Securities proposed to be included in any such
registration exceeds the number of securities which can be sold in such
offering, the Company shall include in such registration only the number of
shares of Registrable Securities which in the opinion of such managing
underwriters can be sold. If the number of shares which can be sold is less
than the number of shares of Registrable Securities proposed to be
registered, the amount of Registrable Securities to be so sold shall be
allocated first, to the shares of Registrable Securities requested to be
registered by the Initiating Holder and then pro rata among the other
Holders of Registrable Securities desiring to participate in such
registration on the basis of the amount of such Registrable Securities
initially proposed to be registered by such other Holders. If the number of
shares which can be sold exceeds the number of shares of Registrable
Securities proposed to be sold, such excess shall be allocated pro rata
among the other holders of securities, if any, desiring to participate in
such registration based on the amount of such securities initially
requested to be registered by such holders or as such holders may otherwise
agree.

        (d) Restrictions on Demand Registrations. The Company shall not be
obligated to effect any G-CO Demand Registration within twelve months after
the effective date of a previous G-CO Demand Registration. The Company
shall not be obligated to effect any W-CO Demand Registration within twelve
months after the effective date of a previous W-CO Demand Registration.

        (e) Selection of Underwriters. If any of the Registrable Securities
covered by a Demand Registration is to be sold in an underwritten offering,
the Initiating Holder shall have the right to select the managing
underwriters; provided that such managing underwriters shall be reasonably
satisfactory to the Company.

        (f) Other Registration Rights. The Company shall not grant to any
Person the right, other than as set forth herein and except to employees of
the Company with respect to registrations on Form S-8 (or any successor
forms thereto), to request the Company to register any securities of the
Company except such rights as are not more favorable than or inconsistent
with the rights granted to the Shareholders herein, without the written
consent of W-CO and the G-CO Representative.

        (g) Effective Period of Demand Registrations. After any Demand
Registration filed pursuant to this Agreement has become effective, the
Company shall use its commercially reasonable efforts to keep such Demand
Registration effective for a period equal to 180 days from the date on
which the SEC declares such Demand Registration effective (or if such
Demand Registration is not effective during any period within such 180
days, such 180-day period shall be extended by the number of days during
such period when such Demand Registration is not effective), or such
shorter period which shall terminate when all of the Registrable Securities
covered by such Demand Registration have been sold pursuant to such Demand
Registration.

        5.  PIGGYBACK REGISTRATIONS.

        If at any time during the Registration Period the Company is not
eligible to use Form S-3 then so long as the Company is not so eligible the
Company shall be subject to the provisions of this Section 5 as follows:

        (a) Right to Piggyback. Whenever the Company proposes to register
any of its common equity securities (other than Registrable Securities)
under the Securities Act (other than a registration statement on Form S-8
or on Form S-4 or any similar successor forms thereto), whether for its own
account or for the account of one or more securityholders of the Company,
and the registration form to be used may be used for any registration of
Registrable Securities (a "Piggyback Registration"), the Company shall give
prompt written notice to all Holders of its intention to effect such a
registration and, subject to Section 5(b), shall include in such
registration all Registrable Securities with respect to which the Company
has received written requests for inclusion therein within 15 days after
the receipt of the Company's notice. The Company may postpone or withdraw
the filing or the effectiveness of a Piggyback Registration at any time in
its sole discretion.

        (b) Priority on Primary Registrations. If a Piggyback Registration
is an underwritten primary registration on behalf of the Company, and the
managing underwriters advise the Company in writing that in their opinion
the number of securities requested to be included in such registration
exceeds the number which can be sold in such offering, the Company shall
include in such registration (i) first, the securities the Company proposes
to sell, (ii) second, the Registrable Securities requested to be included
therein by the Holders thereof, pro rata among the Holders of such
Registrable Securities on the basis of the number of shares requested to be
registered by such Holders, and (iii) third, other securities requested to
be included in such registration pro rata among the holders of such
securities on the basis of the number of shares requested to be registered
by such holders or as such holders may otherwise agree.

        (c) Priority on Secondary Registrations. If a Piggyback
Registration is an underwritten secondary registration on behalf of a
holder of the Company's securities other than Registrable Securities, and
the managing underwriters advise the Company in writing that in their
opinion the number of securities requested to be included in such
registration exceeds the number which can be sold in such offering, the
Company shall include in such registration (i) first, the securities
requested to be included therein by the holders requesting such
registration, (ii) second, the Registrable Securities requested to be
included in such registration, pro rata among the holders of such
securities on the basis of the number of shares requested to be registered
by such holders, and (iii) third, other securities requested to be included
in such registration pro rata among the holders of such securities on the
basis of the number of shares requested to be registered by such holders or
as such holders may otherwise agree.

        6.  HOLDBACK AGREEMENTS.

        Each Shareholder agrees, if so required by a managing underwriter,
not to sell, make any short sale of, loan, grant any option for the
purchase of, effect any public sale or distribution of, make any sale or
distribution pursuant to Rule 144 (or any successor provision) under the
Securities Act of or otherwise dispose of any securities of the Company,
for a period not to exceed 180 days after any underwritten registration
pursuant to this Agreement has become effective, except as part of such
underwritten registration, whether or not such Shareholder participates in
such registration. Each Shareholder agrees that the Company may instruct
its transfer agent to place stop transfer notations in its records to
enforce this Section 6.

        7.  REGISTRATION PROCEDURES.

        In connection with any Registration Statement the following
provisions shall apply:

        (a) The Company shall furnish to W-CO and the G-CO Representative,
prior to the filing thereof with the SEC, copies of any Registration
Statement (including any preliminary prospectus contained therein), and
each amendment thereto and each amendment or supplement, if any, to the
Prospectus included therein and shall reflect in each such document, when
so filed with the SEC, such comments as W-CO and the G-CO Representative
reasonably may propose.

        (b) The Company shall ensure that (i) any Registration Statement
and any amendment thereto and any Prospectus forming part thereof and any
amendment or supplement thereto complies as to form in all material
respects with the Securities Act (ii) any Registration Statement and any
amendment thereto does not, when it becomes effective, contain an untrue
statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein not
misleading and (iii) any Prospectus forming part of any Registration
Statement, and any amendment or supplement to such Prospectus, does not
include an untrue statement of a material fact or omit to state a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading other than, in the
case of clauses (ii) and (iii), any such untrue statement or omission made
therein in reliance upon and conformity with written information furnished
to the Company or its representatives or advisors by or on behalf of W-CO,
any Shareholder in the G-CO Group or the G-CO Representative specifically
for inclusion therein.

        (c) the Company shall promptly advise W-CO and the G-CO
Representative, and, if requested, promptly confirm such advice in writing:

               (i) when a Registration Statement and any amendment or
        supplement thereto has been filed with the SEC and when a
        Registration Statement or any post-effective amendment thereto has
        become effective;

               (ii) of any request by the SEC for amendments or supplements
        to any Registration Statement or the Prospectus included therein or
        for additional information in connection therewith;

               (iii) of the issuance by the SEC of any stop order
        suspending the effectiveness of any Registration Statement or the
        initiation of any actions or proceedings for that purpose;

               (iv) of the receipt by the Company of any notification with
        respect to the suspension of the qualification of the Registrable
        Securities included therein for sale in any jurisdiction or the
        initiation or threatening of any action or proceeding for such
        purpose; and

               (v) to the extent known to the Company, of the happening of
        any event that requires the making of any changes in any
        Registration Statement or Prospectus so that, as of the date of
        such event, the statements therein are not misleading and do not
        omit to state a material fact required to be stated therein or
        necessary to make the statements therein not misleading.

        (d) Subject to Section 8 hereof, the Company shall use its
commercially reasonable efforts to obtain the withdrawal of any order
suspending the effectiveness of any Registration Statement at the earliest
possible time.

        (e) The Company shall furnish to W-CO and the G-CO Representative,
without charge, three copies of each Registration Statement and any
post-effective amendment thereto, including financial statements and
schedules, and, if W-CO or the G-CO Representative so requests in writing,
all exhibits thereto (including those incorporated therein by reference).

        (f) The Company shall furnish W-CO and the G-CO Representative,
without charge, copies of any and all transmittal letters or other
correspondence with the SEC or any other governmental entity relating to a
Registration Statement or the public offering of the Company's securities
thereunder.

        (g) The Company shall, during the Registration Period, deliver to
W-CO and the G-CO Representative, without charge, as many copies of the
Prospectus (including each preliminary Prospectus) included in such
Registration Statement and any amendment or supplement thereto as such
Person may reasonably request; and subject to Section 8 below and W-CO's
and the G-CO Group's compliance with its obligations under Section 7(l),
the Company consents to the use of the Prospectus or any amendment or
supplement thereto by each such Person in connection with the offering and
sale of the Registrable Securities covered by the Prospectus or any
amendment or supplement thereto.

        (h) Prior to any offering of Registrable Securities pursuant to any
Registration Statement, the Company shall use its commercially reasonable
efforts to register or qualify or cooperate with W-CO and the G-CO Group
and their counsel in connection with the registration or qualification of
such Registrable Securities for offer and sale under the securities, blue
sky or similar laws of such jurisdictions as W-CO or the G-CO
Representative reasonably requests in writing and the Company shall use its
commercially reasonable efforts to do any and all other acts or things
necessary or advisable to enable the offer and sale in such jurisdictions
of the Registrable Securities covered by such Registration Statement;
provided, however, that the Company shall not be required to qualify
generally to do business in any jurisdiction where it is not then so
qualified or to take any action which would subject it to general service
of process or to taxation in any such jurisdiction where it is not then so
subject.

        (i) The Company shall cooperate with W-CO and the G-CO
Representative to facilitate the timely preparation and delivery of
certificates representing Registrable Securities to be sold pursuant to any
Registration Statement free of any restrictive legends and in such
denominations and registered in such names as requested prior to such
sales.

        (j) Subject to Section 8 hereof, upon the occurrence of any event
contemplated by paragraph (c)(v) above, the Company shall use its
commercially reasonable efforts to promptly prepare a post-effective
amendment to any Registration Statement or an amendment or supplement to
the related Prospectus or file any other required document so that, as
thereafter delivered to purchasers of the Securities included therein, the
Prospectus will not include an untrue statement of a material fact or omit
to state any material fact necessary to make the statements therein not
misleading, it being understood that the provisions of Section 10 shall
apply to any such statement or omission.

        (k) The Company shall comply in all material respects with all
applicable rules and regulations of the SEC.

        (l) Each holder of Registrable Securities that plans to participate
in a distribution pursuant to a Registration Statement (a "Participating
Holder") shall furnish to the Company such information regarding such
Person and its affiliates and the distribution of such Registrable
Securities as the Company may from time to time reasonably require for
inclusion in such Registration Statement. Each Participating Holder shall
ensure that such information at the time any Registration Statement and any
amendment thereto becomes effective, and at the time any Prospectus or
supplement thereto forming a part of any Registration Statement is
delivered in any offering of Registrable Securities, shall not contain any
untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein
not misleading. Each Participating Holder shall advise the Company and, if
requested by the Company, confirm such advice in writing in the event that
such Participating Holder becomes aware of the happening of any event that
requires the making of any changes in a Registration Statement or
Prospectus so that as of the date of such event the statements therein
provided by a Participating Holder specifically for inclusion therein are
not misleading and do not omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading.

        (m) Subject to Section 8 below, the Company shall, if requested,
promptly incorporate in a Prospectus supplement or post-effective amendment
to a Registration Statement, such information, if any, as the managing
underwriters, W-CO, the G-CO Representative and the Company reasonably
agree should be included therein and shall make all required filings of
such Prospectus supplement or post-effective amendment as soon as
practicable following notification of the matters to be incorporated in
such Prospectus supplement or post-effective amendment.

        (n) If requested by W-CO or the G-CO Representative in connection
with the offering and sale of Registrable Securities pursuant to a
Registration Statement, the Company shall enter into one or more
underwriting agreements with the managing underwriters selected in
accordance with the provisions of this Agreement. Any such underwriting
agreement shall contain such indemnities and other terms and agreements as
are then customarily included in underwriting agreements relating to
secondary public offerings; provided that in no event shall the
indemnification provisions and procedures in such underwriting agreements
be less favorable to the managing underwriters than those contained in
Section 10 hereof.

        (o) The Company shall (i) make, during normal business hours,
reasonably available for inspection by Participating Holder, and any
underwriter participating in any disposition pursuant to a Registration
Statement, and any attorney, accountant or other agent or representative
retained by any Participating Holder or any such underwriter all relevant
financial and other records, pertinent corporate documents and properties
of the Company and its subsidiaries; (ii) cause the Company's officers,
directors and employees to supply all relevant information reasonably
requested by any Participating Holder or any such underwriter, attorney,
accountant, agent or representative in connection with any such
Registration Statement as is customary for similar due diligence
examinations; provided, however, that all such information that is
designated in writing by the Company as confidential at the time of
delivery of such information shall be kept confidential by such
Participating Holder and any such underwriter, attorney, accountant, agent
or representative, unless and to the extent that (x) disclosure is, in the
opinion of counsel to the disclosing party, required to be made in
connection with a court proceeding or required by law or (y) such
information becomes available to the public generally or through a third
party without an accompanying obligation of confidentiality and other than
as a result of a breach of this confidentiality provision; (iii) make such
representations and warranties to the Participating Holders and the
underwriters, if any, in form, substance and scope as are then customarily
made by issuers to underwriters in underwritten secondary public offerings;
(iv) use its commercially reasonable efforts to obtain opinions of counsel
to the Company and updates thereof addressed to each Participating Holder
and the underwriters in customary form and covering such matters as are
then customarily covered in opinions requested in underwritten secondary
public offerings and such other matters as may be reasonably requested by
the underwriters; (v) use its commercially reasonable efforts to obtain
"cold comfort" letters and updates thereof from the independent certified
public accountants of the Company (and, if necessary, any other independent
certified public accountants of any subsidiary of the Company or of any
business acquired by the Company for which financial statements and
financial data are, or are required to be, included in a Registration
Statement), addressed to each Participating Holder and the underwriters, if
any, in customary form and covering matters of the type then customarily
covered in "cold comfort" letters in connection with underwritten secondary
public offerings; and (vi) deliver such documents and certificates as may
be reasonably requested by any Participating Holder and the managing
underwriters, if any. The foregoing actions set forth in clauses (iii),
(iv), (v) and (vi) of this Section 7(o) shall to the extent applicable be
performed at (A) the effectiveness of such Registration Statement and each
post-effective amendment thereto and (B) each closing under any
underwriting agreement as and to the extent required thereunder.

        8.  SUSPENSION OF OFFERINGS IN CERTAIN CIRCUMSTANCES.

        The Company shall be entitled for the period referred to below to
postpone the filing of any Registration Statement or the taking of any
other action otherwise required to be prepared, filed or taken by it
pursuant to Sections 3, 4 or 7 hereof and to direct the suspension of any
public offering, sale or distribution of Registrable Securities pursuant to
this Agreement if a majority of the Board of Directors determines in good
faith that any disclosure that would be required in connection therewith
would have a material adverse effect on the Company and its subsidiaries
taken as a whole or any financing, acquisition, disposition, merger,
business combination, corporate reorganization, or other transaction or
development involving the Company or any subsidiary of the Company (a
"Suspension Determination"). Such postponement or direction shall continue
until such time as a majority of the Board of Directors determines that the
preparation or filing of such Registration Statement or the taking of any
such action or such public offering, sale or distribution would no longer
have such a material adverse effect (a "Suspension Period"). During the
pendency of any Suspension Period, W-CO and the G-CO Representative (upon
behalf of the Shareholders comprising the G-CO Group) shall provide prompt
written notice to the Company whenever either has a present bona fide
intention to offer Registrable Securities hereunder (a "Bona Fide Notice").
During the pendency of any Suspension Period and during any period
thereafter during which the Company is prevented from making a Suspension
Determination, W-CO and the G-CO Representative (upon behalf of the
Shareholders comprising the G-CO Group) shall provide prompt written notice
to the Company whenever the applicable party ceases to have a present bona
fide intention to offer Registrable Securities (a "Cessation Notice"). Each
day commencing with the day on which a Bona Fide Notice is delivered and
ending on the day on which a Cessation Notice is delivered shall be
referred to as a "Blackout Day". Any particular Suspension Period shall not
continue for more than 90 Blackout Days and there shall not be more than
150 Blackout Days in any 365-day period. If a Shelf Registration Statement
is not in effect at and after the end of a Suspension Period and W-CO or
the Shareholders comprising the G-CO Group, having delivered a Bona Fide
Notice, was prevented from offering Registrable Securities hereunder
because of the pendency of such Suspension Period, the Company shall not
make another Suspension Determination until the earlier of the consummation
of the offering that was previously postponed because of such Suspension
Period or the delivery of a Cessation Notice. If a Shelf Registration
Statement is in effect at and after the end of a Suspension Period that
includes a Blackout Day, the Company shall not make another Suspension
Determination within 45 days of the expiration of such Suspension Period
unless W-CO and the G-CO Representative (upon behalf of the Shareholders
comprising the G-CO Group), as applicable, earlier delivers a Cessation
Notice. The Company shall, as promptly as practicable, give W-CO and the
G-CO Representative written notice of any Suspension Determination. W-CO
and the Shareholders comprising the G-CO Group shall be obligated to
suspend any public offering, sale or distribution of Registrable Securities
in accordance with the Company's directions and for the period provided in
this Section 8. If the Company shall suspend or otherwise withdraw any
Demand Registration pursuant to this Section 8 (a "Withdrawn Demand
Registration"), the Initiating Holder of the Registrable Securities
remaining unsold and originally covered by such Withdrawn Demand
Registration shall be entitled to a replacement Demand Registration which
(subject to the provisions of Section 4 hereof) the Company shall use its
commercially reasonable efforts to keep effective for a period commencing
on the effective date of such Demand Registration and ending on the earlier
to occur of the date (i) which is 180 days from the effective date of such
Demand Registration and (ii) on which all of the Registrable Securities
covered by such Demand Registration have been sold. Such additional Demand
Registration otherwise shall be subject to all of the provisions of this
Agreement.

        9.  REGISTRATION EXPENSES.

        (a) All expenses incident to the Company's performance of or
compliance with provisions of this Agreement relating to the registration
of Registrable Securities, including, without limitation, all registration
and filing fees, fees and expenses of compliance with securities or blue
sky laws, listing application fees, printing expenses, transfer agent's and
registrar's fees, cost of distributing prospectuses in preliminary and
final form as well as any supplements thereto, and fees and disbursements
of counsel for the Company and all independent certified public accountants
and other Persons retained by the Company (all such expenses being herein
called "Registration Expenses") (but not including any underwriting
discounts or commissions attributable to the sale of Registrable Securities
or fees and expenses of more than one counsel representing the Holders of
Registrable Securities), shall be borne by the Company. In addition, the
Company shall pay its internal expenses (including, without limitation, all
salaries and expenses of its officers and employees (and any agents,
consultants or other Persons acting in a similar capacity on behalf of the
Company) performing legal or accounting duties), the expense of any annual
audit or quarterly review, the expense of any liability insurance and the
expenses and fees for listing the securities to be registered on each
securities exchange on which they are to be listed.

        (b) In connection with each registration initiated hereunder
(whether a Shelf Registration, Demand Registration or a Piggyback
Registration), the Company shall reimburse the Holders covered by such
registration or sale for the reasonable fees and disbursements of one law
firm chosen by the Holders of a majority of the number of shares of
Registrable Securities included in such registration or sale.

        (c) The obligation of the Company to bear the expenses described in
Section 9(a) and to reimburse the Holders for the expenses described in
Section 9(b) shall apply irrespective of whether a registration becomes
effective, is withdrawn or suspended and irrespective of when any of the
foregoing shall occur; provided, however, that Registration Expenses for
any registration statement withdrawn solely at the request of a Holder of
Registrable Securities (unless withdrawn following postponement of filing
by the Company in accordance with Section 8) or any supplements or
amendments to a registration statement or prospectus resulting from a
misstatement furnished to the Company by a Holder shall be borne by such
Holder.

        10.  INDEMNIFICATION.

        (a) The Company agrees to indemnify, to the fullest extent
permitted by law, each Holder, its officers, directors and affiliates and
each Person who controls such Holder (within the meaning of the Securities
Act) against all losses, claims, damages, liabilities and expenses arising
out of or based upon any untrue or alleged untrue statement of material
fact contained in any Registration Statement, Prospectus or preliminary
prospectus or any amendment thereof or supplement thereto or any omission
or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as
the same are made in reliance on and in conformity with information
relating to such Holder furnished in writing to the Company by such Holder
expressly for use therein or caused by such Holder's failure to deliver to
such Holder's immediate purchaser a copy of the Registration Statement or
Prospectus or any amendments or supplements thereto (if the same was
required by applicable law to be so delivered) after the Company has
furnished such Holder with a sufficient number of copies of the same. In
connection with an underwritten offering, the Company shall indemnify such
underwriters, their officers and directors and each Person who controls
such underwriters (within the meaning of the Securities Act) to the same
extent as provided above with respect to the indemnification of the
Holders.

        (b) In connection with any Registration Statement in which a Holder
of Registrable Securities is participating, each such Holder shall furnish
to the Company in writing such information and affidavits as the Company
reasonably requests for use in connection with any such Registration
Statement or Prospectus and, to the fullest extent permitted by law, shall
indemnify the Company, its directors and officers and each Person who
controls the Company (within the meaning of the Securities Act) against all
losses, claims, damages, liabilities and expenses arising out of or based
upon any untrue or alleged untrue statement of material fact contained in
the Registration Statement, Prospectus or preliminary prospectus or any
amendment thereof or supplement thereto or any omission or alleged omission
of a material fact required to be stated therein or necessary to make the
statements therein not misleading, but only to the extent that such untrue
statement or omission is made in reliance on and in conformity with
information or affidavit so furnished in writing by such Holder expressly
for use in the Registration Statement; provided, however, that the
obligation to indemnify shall be several, not joint and several, among such
Holders and the liability of each such Holder shall be in proportion to and
limited to the net amount received by such Holder from the sale of
Registrable Securities pursuant to such Registration Statement.

        (c) Any Person entitled to indemnification hereunder shall (i) give
prompt written notice to the indemnifying party of any claim with respect
to which it seeks indemnification and (ii) unless in such indemnified
party's reasonable judgment a conflict of interest between such indemnified
and indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel
reasonably satisfactory to the indemnified party. If such defense is
assumed, the indemnifying party shall not be subject to any liability for
any settlement made by the indemnified party without its consent (but such
consent will not be unreasonably withheld). An indemnifying party who is
not entitled to, or elects not to, assume the defense of a claim shall not
be obligated to pay the fees and expenses of more than one counsel for all
parties indemnified by such indemnifying party with respect to such claim,
unless in the reasonable judgment of any indemnified party there may be one
or more legal or equitable defenses available to such indemnified party
which are in addition to or may conflict with those available to another
indemnified party with respect to such claim. Failure to give prompt
written notice shall not release the indemnifying party from its
obligations hereunder.

        (d) The indemnification provided for under this Agreement shall
remain in full force and effect regardless of any investigation made by or
on behalf of the indemnified party or any officer, director or controlling
Person of such indemnified party and shall survive the transfer of
securities.

        (e) If the indemnification provided for in or pursuant to this
Section 10 is due in accordance with the terms hereof, but is held by a
court to be unavailable or unenforceable in respect of any losses, claims,
damages, liabilities or expenses referred to herein, then each applicable
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified person as a
result of such losses, claims, damages, liabilities or expenses in such
proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the
other in connection with the statements or omissions which result in such
losses, claims, damages, liabilities or expenses as well as any other
relevant equitable considerations. The relative fault of the indemnifying
party on the one hand and of the indemnified person on the other shall be
determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party, and by such party's
relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. In no event shall the
liability of any selling Holder be greater in amount than the amount of net
proceeds received by such Holder upon such sale or the amount for which
such indemnifying party would have been obligated to pay by way of
indemnification if the indemnification provided for under Section 10(a) or
10(b) hereof had been available under the circumstances.

        11.  PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.

        No Person may participate in any registration hereunder which is
underwritten unless such Person (a) agrees to sell such Person's securities
on the basis provided in any underwriting arrangements approved by the
Person or Persons entitled hereunder to approve such arrangements and (b)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents required under the terms of
such underwriting arrangements.

        12.  THE G-CO REPRESENTATIVE.

        (a) Each Shareholder in the G-CO Group, by its acceptance of the
benefits under this Agreement, authorizes, directs and appoints the G-CO
Representative to act as its sole and exclusive agent, attorney-in-fact and
representative, and authorizes and directs the G-CO Representative to (i)
take any and all actions (including, without limitation, executing and
delivering any documents, incurring any costs and expenses for the account
of the G-CO Group and making any and all determinations) which may be
required or permitted by this Agreement to be taken by the G-CO
Representative or the G-CO Group, (ii) exercise such other rights, powers
and authority as are authorized, delegated or granted to the G-CO
Representative hereunder and (iii) exercise such rights, powers and
authority as are incidental to the foregoing. Any such actions taken,
exercises of rights, powers or authority, and any decision or determination
made by the G-CO Representative consistent therewith, shall be absolutely
and irrevocably binding on each Shareholder in the G-CO Group as if such
Shareholder personally had taken such action, exercised such rights, powers
or authority or made such decision or determination in such Shareholder's
individual capacity. Notwithstanding any other provision of this Agreement,
each Shareholder in the G-CO Group irrevocably relinquishes its right to
act independently and other than through the G-CO Representative, except as
expressly provided for under this Agreement. The G-CO Representative hereby
accepts the foregoing authorization and appointment and agrees to serve as
the G-CO Representative in accordance with this Agreement. In the event
that a G-CO Representative resigns or otherwise ceases to be a G-CO
Representative, the G-CO Group shall appoint a new G-CO Representative
within 15 Business Days of such Person ceasing to be a G-CO Representative.

        (b) The provisions of this Section 12 shall in no way impose any
obligations on the Company or W-CO. In particular, notwithstanding any
notice received by the Company or W-CO to the contrary, the Company and
W-CO (i) shall be fully protected in relying upon and shall be entitled to
rely upon, shall have no liability to any Shareholder in the G-CO Group
with respect to, any and all damages and losses arising out of actions,
decisions and determinations of the G-CO Representative and (ii) shall be
entitled to assume that all actions, decisions and determinations of the
G-CO Representative are fully authorized by the Shareholders in the G-CO
Group.

        13.  CERTAIN COVENANTS OF THE SHAREHOLDERS.

        (a) Lockup. Each Shareholder agrees not to, directly or indirectly,
transfer, sell, assign, exchange, pledge, hypothecate, grant a security
interest in, or otherwise dispose of or offer to transfer, sell, assign,
exchange, encumber or otherwise dispose of any Ordinary Shares until one
hundred and eighty (180) days after the date hereof (the "Lockup Period").

        (b) Notification of Dispositions, etc. Each Shareholder agrees to
notify in writing, the Company, W-CO and the G-CO Representative upon the
transfer, sale, assignment, exchange, pledge, hypothecation, granting of a
security interest in, or other disposition of any Ordinary Shares. Such
notification shall identify the number of Ordinary Shares involved in such
transaction and the number of Ordinary Shares Beneficially Owned by such
Shareholder immediately prior to and immediately following such
transaction. Upon the written request of W-CO or the Company, the G-CO
Representative will certify in writing the number of Ordinary Shares
Beneficially Owned by the G-CO Group as of the date of such written
request. Upon the written request of the G-CO Representative or the
Company, W-CO will certify in writing the number of Ordinary Shares
Beneficially Owned by W-CO as of the date of such written request.

        14.  TERMINATION.

        (a) This Agreement shall continue in full force and effect from the
date hereof through the earliest of the following dates, upon which this
Agreement will terminate in its entirety:

               (i) The first Business Day following the Company's 2003
Annual General Meeting of Shareholders.

               (ii) The day upon which the G-CO Group collectively ceases
to be the Beneficial Owners of at least 25% of the Ordinary Shares of the
Company Beneficially Owned by the G-CO Group on the Closing Date.

               (iii) The day upon which W-CO ceases to be a Beneficial
Owner of at least 25% of the Ordinary Shares of the Company Beneficially
Owned by W-CO on the Closing Date.

        (b) In determining whether or not this Agreement terminates under
Section 14(a)(ii) or Section 14(a)(iii), the calculation used to make such
a determination shall take into account and appropriately adjust for any
stock splits, reverse stock splits, stock dividends, reclassifications,
recapitalizations and similar transactions after the date hereof.

        (c) If at any time during the term of this Agreement a Shareholder
no longer Beneficially Owns any Ordinary Shares, this Agreement shall
terminate as to such Shareholder only (and not as to any other Shareholder)
and thereafter such Shareholder shall cease to have any rights or
obligations under this Agreement (other than such rights and obligations
under Section 10 above which shall survive such a termination).

                   WILLIAMS VOTING AND LOCK-UP AGREEMENT

            This Voting and Lock-Up Agreement (this "Agreement") is made
and entered into as of April 5, 2001 by and between Globex Energy, Inc., a
Delaware corporation ("G-Co"), and Williams Global Energy (Cayman) Limited,
a Cayman Islands corporation ("W-Co").

            WHEREAS, concurrently with the execution of this Agreement,
Apco Argentina, Inc., a Cayman Islands corporation (the "Company"), Apco
Delaware, Inc., a Delaware corporation and wholly-owned subsidiary of the
Company ("Merger Subsidiary"), and G-Co, have entered into an Agreement and
Plan of Merger dated as of April 5, 2001 (the "Merger Agreement"),
providing for the merger of Merger Subsidiary with and into G-Co (the
"Merger"), pursuant to which G-Co will become a wholly-owned subsidiary of
the Company;

            WHEREAS, W-Co is the sole record and beneficial owner of the
number of shares of capital stock, other equity interests and securities
convertible into capital stock or other equity interests in the Company as
is indicated on the applicable signature page of this Agreement (the
"Shares"); and

            WHEREAS, in consideration of and to induce the execution of the
Merger Agreement by G-Co, W-Co agrees to certain transfer restrictions and
voting requirements to facilitate consummation of the Merger as more fully
described below.

            NOW, THEREFORE, in consideration of the mutual promises and the
mutual covenants and agreements contained herein, the parties agree as
follows:

            1. Agreement to Retain Shares. Except as expressly contemplated
by the Merger Agreement, W-Co agrees not to transfer, assign, sell,
exchange, pledge, hypothecate, grant a security interest in or otherwise
dispose of, or offer to transfer, assign, sell, exchange, encumber or
otherwise dispose of, or grant any proxy or power of attorney, deposit any
Shares into a voting trust or enter into a voting agreement, understanding
or arrangement with respect to any of the Shares at any time prior to
consummation of the Merger or the Expiration Date, as defined herein. The
"Expiration Date" shall mean the date on which the Merger Agreement shall
have been terminated pursuant to Article VII of the Merger Agreement.

            2. Agreement to Vote Shares. At any meeting of the stockholders
of the Company called with respect to the Merger, the Merger Agreement and
any other transactions contemplated thereby, and at any adjournment or
adjournments thereof, and with respect to any consent or proxies solicited
with respect to the Merger, the Merger Agreement and any other transactions
contemplated thereby, W-Co shall vote the Shares (a) in favor of the
issuance of shares in the Merger and the approval of the amendments to the
Company's Articles of Association and Memorandum of Association as
contemplated by the Merger Agreement, including any amendments thereto, and
any matter which could reasonably be expected to facilitate the Merger and
(b) against any alternative transaction or any other matter which could
reasonably be expected to facilitate the consummation of an alternative
transaction. W-Co, as the holder of Shares, shall be present, in person or
by proxy, at all meetings of stockholders of the Company or at any
adjournment or adjournments thereof so that all Shares are counted for the
purpose of determining the presence of a quorum at such meetings.

            3. Additional Purchases. For purposes of this Agreement, the
term "Shares" shall include any shares of capital stock or other equity
interests of the Company which W-Co purchases or otherwise acquires after
the execution of this Agreement and prior to the Expiration Date,
including, without limitation, by exercise of options or warrants.

            4. Representations, Warranties and Covenants of W-Co. W-Co
hereby represents, warrants and covenants to G-Co that, except as
specifically described on Annex A to this Agreement, W-Co (i) is the sole
record and beneficial owner of the Shares, which at the date hereof and at
all times until the Expiration Date will be free and clear of any liens,
claims, options, charges or other encumbrances, (ii) does not own
beneficially or of record any shares of stock or other equity interest of
the Company other than the Shares and (iii) has full power and authority to
make, enter into, deliver and carry out the terms of this Agreement. W- Co
hereby further represents, warrants and covenants that (i) this Agreement
constitutes the legal, valid and binding obligation of W-Co, and (ii)
neither the execution of this Agreement by W-Co nor the consummation of the
transactions contemplated hereby will result in a breach or violation of
the terms of any agreement by which W-Co is bound or of any decree,
judgment, order, law or regulation now in effect of any court or other
governmental body applicable to W- Co.

            5. Representations, Warranties and Covenants of G-Co. G-Co
represents, warrants and covenants to W-Co that this Agreement (i) has been
authorized by all necessary corporate action on the part of G-Co and has
been duly executed by a duly authorized officer of G-Co and (ii)
constitutes the legal, valid and binding obligation of G-Co. Neither the
execution of this Agreement by G-Co nor the consummation of the
transactions contemplated hereby will result in a breach or violation of
the terms of any agreement by which G-Co is bound or of any decree,
judgment, order, law or regulation now in effect of any court or other
governmental body applicable to G-Co.

            6. Additional Documents. W-Co and G-Co hereby covenant and
agree to execute and deliver any additional documents necessary or
desirable, in the reasonable opinion of G-Co or W-Co, as the case may be,
to carry out the intent of this Agreement.

            7. Consent and Waiver. W-Co hereby gives any consent or waivers
that are reasonably required for the consummation of the Merger under the
terms of any agreement to which W-Co is a party or pursuant to any rights
W-Co may have.

            8.    Miscellaneous.

            (a) Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction
to be invalid, void or unenforceable, the remainder of the terms,
provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or
invalidated.

            (b) Binding Effect and Assignment. This Agreement and all of
the provisions hereof shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns, but,
except as otherwise specifically provided herein, neither this Agreement
nor any of the rights, interests or obligations of the parties hereto may
be assigned by any of the parties without the prior written consent of the
other.

            (c) Amendments and Modifications. This Agreement may not be
modified, amended, altered or supplemented except upon the execution and
delivery of a written agreement executed by the parties hereto.

            (d) Specific Performance; Injunctive Relief. The parties hereto
acknowledge that G-Co will be irreparably harmed and that there will be no
adequate remedy at law for a violation of any of the covenants or
agreements of W-Co set forth herein. Therefore, it is agreed that, in
addition to any other remedies which may be available to G-Co upon such
violation, G-Co shall have the right to enforce such covenants and
