Item 1.01. Entry into a Material Definitive Agreement.

     On May 1, 2005, The Williams Companies, Inc. (“Williams”) entered into a Credit Agreement among Williams, Northwest Pipeline Corporation, Transcontinental Gas Pipe Line Corporation, and Williams Partners L.P. (collectively, the “Borrowers”), the lenders from time to time parties thereto, and Citibank, N.A., as administrative agent (the “Credit Agreement”).

     The Credit Agreement replaces the Amended and Restated Credit Agreement, dated May 20, 2005, by and among the Borrowers, the several lenders from time to time parties thereto, and Citicorp USA, Inc., as administrative agent and collateral agent (the “Old Credit Agreement”).

     The Credit Agreement consists of a $1.5 billion senior unsecured revolving line of credit. The Credit Agreement has a term of three years. Borrowings under the Credit Agreement bear interest at a variable interest rate based on either LIBOR or a base rate, in either case plus an applicable margin that varies depending upon the rating of the applicable borrower’s senior unsecured long-term debt.

     The Credit Agreement is guaranteed by Williams Gas Pipeline Company, LLC. The obligations of Williams Partners, L.P. are guaranteed by Williams.

     The Credit Agreement contains a number of restrictions on the Borrowers’ business, including, but not limited to, restrictions on certain of the Borrowers’ and certain of the Borrowers’ subsidiaries’ ability to grant liens on assets, merge, consolidate, or sell assets; incur indebtedness; engage in transactions with related parties; and make distributions on equity interests. In addition, Williams is at certain times subject to a minimum ratio of consolidated EBITDA to interest expense financial maintenance covenant. The Credit Agreement also contains affirmative covenants and events of default, including a cross acceleration to debt in a principal amount of $100 million or greater, and the occurrence of a change of control. Failure to comply with these covenants, or the occurrence of an event of default, could result in acceleration of the Borrowers’ debt and other financial obligations under the Credit Agreement.

     As of May 1, 2005, there are no outstanding borrowings under the Credit Agreement.

     The foregoing does not constitute a complete summary of the terms of the Credit Agreement, which is attached hereto as Exhibit 10.1. The description of the terms of the Credit Agreement is qualified in its entirety by reference to such exhibit.

     A copy of the press release announcing the Credit Agreement is furnished herewith as Exhibit 99.1.

Item 1.02. Termination of a Material Definitive Agreement.

     (a) Revolving Credit Advances. Each Bank severally agrees, on the terms and conditions hereinafter set forth, to make Revolving Credit Advances to each Borrower from time to time on any Business Day during the period from the Effective Date until the Termination Date; provided that in no event shall the sum of the aggregate amount of all Revolving Credit Advances owed to such Bank outstanding to such Borrower plus the aggregate amount of all Letter of Credit Liabilities held by such Bank for all Letters of Credit issued at the request of such Borrower exceed, at the time any Revolving Credit Advance is made by such Bank (and giving effect to such Revolving Credit Advance), such Bank’s Revolving Credit Commitment for such Borrower at such time; provided further that in no event shall the sum of the aggregate amount of all Revolving Credit Advances to all Borrowers owed to any Bank plus the aggregate amount of all Letter Credit Liabilities held by such Bank for all Letters of Credit exceed, at the time any Revolving Credit Advance is made by such Bank (and giving effect to such Revolving Credit Advance), the Revolving Credit Commitment of such Bank for TWC. Each Revolving Credit Borrowing to a Borrower shall be in an aggregate amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof and shall consist of Revolving Credit Advances of the same Type made to such Borrower on the same day by the Banks ratably according to their respective Revolving Credit Commitments for such Borrower and, if such Revolving Credit Advances are Eurodollar Rate Advances, having the same Interest Period. Within the limits of this Section 2.1(a), a Borrower may borrow under this Section 2.1(a), prepay pursuant to Section 2.5 and reborrow under this Section 2.1(a).

     (b) Letters of Credit. Each Issuing Bank agrees, on the terms and conditions hereinafter set forth, to issue letters of credit in Dollars at the request of any Borrower (such issuance, and any funding of a draw thereunder, are deemed made by the Issuing Banks in reliance on the agreements of the other Banks pursuant to Section 2.2) from time to time on any Business Day during the period from the Effective Date until the earlier of (A) the date of termination in whole of the Commitments pursuant to Section 2.4 or 6.1 or (B) the date that is 30 days prior to the date listed in clause (i) of the definition herein of “Termination Date” in an aggregate Available Amount such that, immediately after giving effect to the issuance of each Letter of Credit, the aggregate Letter of Credit Liabilities (i) in respect of all Letters of Credit issued by the Issuing Banks do not exceed at the time of any such issuance the aggregate of all Letter of Credit Commitments at such time, (ii) in respect of all Letters of Credit issued by any Issuing Bank do not exceed at the time of any such issuance the Letter of Credit Commitment of such Issuing Bank at such time, and (iii) in respect of all Letters of Credit outstanding at the time of any such issuance issued at the request of any Borrower do not exceed an amount equal to the Revolving Credit Commitments of the Banks for such Borrower at such time minus the aggregate amount of all Revolving Credit Advances outstanding to such Borrower at such time; provided that in no event shall the sum of the aggregate amount of all Revolving Credit Advances to all Borrowers owed to any Bank plus the aggregate amount of all Letter of Credit Liabilities held by such Bank for all Letters of Credit exceed the Revolving Credit Commitment of such Bank for TWC at the time of any such issuance; provided further that no Issuing Bank shall be under any obligation to issue a letter of credit if, in the reasonable opinion of such Issuing Bank, such letter of credit would violate or conflict with any regulatory or legal restriction applicable to such Issuing Bank, or an internal policy, procedure or guideline of such Issuing Bank generally applicable to the issuance of letters of credit. No Letter of Credit shall have an expiration date

(including all rights of a Borrower or the beneficiary to require renewals, but excluding automatic renewal provisions if the relevant Issuing Bank can, in its discretion, refuse to renew and thereby cause the expiration date to occur no later than 7 Business Days prior to the date set forth in clause (i) of the definition herein of Termination Date) later than 7 Business Days prior to the date set forth in clause (i) of the definition herein of Termination Date.

     (2) Additionally, if (i) an Issuing Bank has, at the request of a Borrower, issued a letter of credit in Dollars other than under this Agreement, (ii) such Borrower decides to add such letter of credit (an “Added Letter of Credit”) to this Agreement as a Letter of Credit and (iii) such Issuing Bank consents in writing (such consent, and any funding of a draw under such letter of credit, are deemed made by such Issuing Bank in reliance on the agreements of the other Banks pursuant to this Section 2.2) to such letter of credit becoming an Added Letter of Credit, then such Borrower shall give the Agent and such Issuing Bank at least three Business Days’ (or such shorter period as agreed to by the Agent and such Issuing Bank) prior notice that such Borrower requests that such letter of credit be so added by delivering a Notice of Letter of Credit specifying the Business Day such letter of credit is to be added to this Agreement and attaching thereto a copy of such letter of credit. On the Business Day so specified for such letter of credit, such letter of credit shall become an Added Letter of Credit and become a Letter of Credit deemed issued under this Agreement by the Issuing Bank specified in the relevant Notice of Letter of Credit (the date such letter of credit so becomes an Added Letter of Credit being the “Added L/C Effective Date” for such letter of credit), if immediately after giving effect to such letter of credit becoming a Letter of Credit (A) as to each Bank, the sum of the aggregate amount of all Revolving Credit Advances to all Borrowers owed to such Bank plus the aggregate amount of all Letter of Credit Liabilities held by such Bank for all Letters of Credit does not exceed the Revolving Credit Commitment of such Bank for TWC, (B) the aggregate Letter of Credit Liabilities (i) in respect of all Letters of Credit issued by the Issuing Banks do not exceed the aggregate of all Letter of Credit Commitments at such time, (ii) in respect of all Letters of Credit issued by such Issuing Bank do not exceed the Letter of Credit Commitment of such Issuing Bank at such time, and (iii) in respect of all Letters of Credit outstanding issued at the request of any Borrower do not exceed an amount equal to the Revolving Credit Commitments of the Banks for such Borrower at such time minus the aggregate amount of all Revolving Credit Advances outstanding to such Borrower at such time, (C) such letter of credit shall have an expiration date (including all rights of a Borrower or the beneficiary to require renewals, but excluding automatic renewal provisions if such Issuing Bank can, in its discretion, refuse to renew and thereby cause the expiration date to occur no later than 7 Business Days prior to the date set forth in clause (i) of the definition herein of Termination Date) no later than 7 Business Days prior to the date set forth in

clause (i) of the definition herein of Termination Date, and (D) such Issuing Bank notifies the Agent, on or before such Added L/C Effective Date, that such letter of credit is or will become, as of such Added L/C Effective Date, an Added Letter of Credit.

     (3) The Issuing Bank issuing any Letter of Credit may specify therein whether such Letter of Credit will be subject to the International Standby Practices, the Uniform Customs and Practices or other practices. A Letter of Credit will be deemed to be issued at the request of (i) NWP, if NWP gives the Notice of Letter of Credit in respect of such Letter of Credit; (ii) TGPL, if TGPL gives the Notice of Letter of Credit in respect of such Letter of Credit, (iii) MLP, if MLP gives the Notice of Letter of Credit in respect of such Letter of Credit and (iv) TWC, if neither NWP nor TGPL nor MLP gives the Notice of Letter of Credit in respect of such Letter of Credit.

     (b) Participations in Letters of Credit. On each day during the period commencing with the issuance by any Issuing Bank of any Letter of Credit at the request of any Borrower and until such Letter of Credit shall have expired or been terminated, the Letter of Credit Commitment of each Issuing Bank shall be deemed to be utilized for all purposes of this Agreement in an amount equal to the Available Amount of such Letter of Credit. Each Bank agrees that, upon the issuance of any Letter of Credit hereunder by any Issuing Bank, it shall automatically acquire a participation in such Issuing Bank’s liability under such Letter of Credit in an amount equal to such Bank’s LC Participation Percentage of such liability, and each Bank thereby shall absolutely, unconditionally and irrevocably assume, as primary obligor and not as surety, liability to pay such amount and shall be unconditionally obligated to such Issuing Bank to the extent provided in this Section 2.2.

     (c) Reimbursement Obligations; Notice of Drawings. Upon receipt from the beneficiary of any Letter of Credit of any demand for payment under such Letter of Credit, the Issuing Bank that issued such Letter of Credit shall promptly notify the applicable Borrower (through the Agent) of the amount to be paid by such Issuing Bank as a result of such demand and the date on which payment is to be made by such Issuing Bank to such beneficiary in respect of such demand, which shall be (unless same day payment is required by the terms of such Letter of Credit pursuant to a request of such Borrower) at least one Business Day after the date on which the Agent shall deliver such notice to the applicable Borrower pursuant to this sentence. Each Borrower hereby unconditionally agrees to pay and reimburse the Agent for the account of the Issuing Bank that issued a Letter of Credit at the request of such Borrower for the amount of each demand for payment under such Letter of Credit that is in substantial compliance with the provisions of such Letter of Credit at or prior to the date on which payment is to be made by such Issuing Bank to the beneficiary thereunder (or on the next Business Day, if same day payment is required by the terms of such Letter of Credit pursuant to a request of such Borrower and if the notice to such Borrower from such Issuing Bank in respect of such demand contemplated by the first sentence of this Section 2.2(c) is not given prior to 9:00 a.m. (New York City time) on such date), without presentment, demand, protest or other formalities of any kind, in each case together with interest thereon at a rate per annum equal to the Base Rate plus the Applicable Margin in effect from time to time for such Borrower as to Base Rate Advances, for the period from the date payment is made by such Issuing Bank to the beneficiary thereunder until the date of such reimbursement. Each Borrower’s obligations to reimburse each Issuing Bank as provided herein shall be absolute, unconditional and irrevocable under all circumstances whatsoever, including the following circumstances: (i) any lack of validity of this Agreement, the other Credit Documents or the other documents to be delivered under this Agreement; (ii) the existence of any claim, set-off, defense or other right that a Borrower may have at any time against the Agent, any Bank, any Issuing Bank or any other Person, whether in connection with the transactions contemplated by this Agreement or any unrelated transaction; (iii) any action or inaction taken or suffered by any Issuing Bank under a Letter of Credit if taken in good faith and in conformity with applicable law; (iv) the payment by any Issuing Bank under a Letter of Credit against presentation of a demand, statement or other document which in the sole discretion of such Issuing Bank substantially complies with the terms

of such Letter of Credit, including any demand, statement or other document which is forged, fraudulent, invalid or inaccurate in any respect; (v) any exchange, release or non-perfection of any collateral for, or any release or amendment or waiver of or consent to departure from any guarantee of, all or any of the Obligations in respect of any Letter of Credit; and (vi) any determination of invalidity or unenforceability with respect to any Letter of Credit after payment by an Issuing Bank thereunder.

     (d) Payments by Banks to Issuing Banks. To the extent that a Borrower fails to make any payment to an Issuing Bank that such Borrower is required to make pursuant to Section 2.2(c), each Bank (other than such Issuing Bank) shall pay to the Agent, for the account of such Issuing Bank in Dollars and in immediately available funds, the amount of such Bank’s LC Participation Percentage of any payment under a Letter of Credit upon notice by such Issuing Bank (through the Agent) to such Bank requesting such payment and specifying such amount. Each such Bank’s obligation to make such payment to the Agent for the account of such Issuing Bank under this Section 2.2(d), and such Issuing Bank’s right to receive the same, shall be absolute and unconditional and shall not be affected by any circumstance whatsoever (other than the gross negligence or willful misconduct of such Issuing Bank in making payment under such Letter of Credit), including the failure of any other Bank to make its payment under this Section 2.2(d), the financial condition of a Borrower (or any other Person), the existence of any Default or Event of Default, the incorrectness of any representation or warranty, the existence of any claim, set-off, defense or other right, any amendment, extension or other modification of any Letter of Credit or the reduction or termination of the Letter of Credit Commitments or the Revolving Credit Commitments. If any Bank shall default in its obligation to make any such payment to the Agent for the account of an Issuing Bank, for so long as such default shall continue the Agent may, at the request of such Issuing Bank, withhold from any payments received by the Agent under this Agreement for the account of such Bank the amount so in default and, to the extent so withheld, pay the same to such Issuing Bank for application to such defaulted obligation.

     (e) Participations in Reimbursement Obligations. Upon the making of each payment by a Bank to an Issuing Bank pursuant to Section 2.2(d) in respect of any Letter of Credit, such Bank shall, automatically and without any further action on the part of the Agent, any Issuing Bank or such Bank, acquire (i) a funded participation in an amount equal to such payment in the Reimbursement Obligation owing to such Issuing Bank by the applicable Borrower hereunder and under the Letter of Credit Documents relating to such Letter of Credit and (ii) a participation in a percentage equal to such Bank’s LC Participation Percentage in any interest or other amounts payable by the applicable Borrower hereunder and under such Letter of Credit Documents in respect of such Reimbursement Obligation (other than the Fronting Fee contemplated by Section 2.11(b)(i)). Upon receipt by any Issuing Bank from or for the account of a Borrower of any payment in respect of any Reimbursement Obligation or any such interest or other amount (including by way of setoff or application of proceeds of any collateral security or the withdrawal and application of funds from an LC Cash Collateral Account in respect of such Borrower), such Issuing Bank shall promptly pay to the Agent, for the account of each Bank entitled thereto, such Bank’s LC Participation Percentage of such payment, each such payment by such Issuing Bank to be made in the same currency and funds in which received by such Issuing Bank. In the event any payment received by any Issuing Bank and so paid to the Banks hereunder is rescinded or must otherwise be returned by such Issuing Bank, each Bank shall, upon the request of such Issuing Bank (through the Agent), repay to such Issuing Bank (through the Agent) the portion of such payment paid to such Bank.

     (f) Information Provided by Issuing Banks to Banks. Promptly after the issuance of or amendment to any Letter of Credit, the Issuing Bank that issued such Letter of Credit will notify the Agent and the applicable Borrower in writing of such issuance or amendment and such notice shall be accompanied by a copy of such issued or amended Letter of Credit. Upon receipt of such notice, the Agent shall notify each Bank of such issuance or amendment and, if requested by a Bank, the Agent shall

provide such Bank with copies of such issued or amended Letter of Credit and any Letter of Credit Documents related thereto delivered to the Agent.

     (g) Conditions Precedent to Issuance, Modification and Addition. The obligation of any Issuing Bank to issue a Letter of Credit shall be subject to satisfaction of each of the conditions precedent set forth in Section 3.2, and shall further be subject to the conditions precedent that (i) such Letter of Credit shall be in such form and contain such terms as shall be reasonably satisfactory to such Issuing Bank consistent with its then current practices and procedures of general applicability with respect to letters of credit of the same type and (ii) the applicable Borrower shall have executed and delivered such applications, agreements and other instruments relating to such Letter of Credit as such Issuing Bank shall have reasonably requested consistent with its then current practices and procedures of general applicability with respect to letters of credit of the same type; provided that in the event of any conflict between any such application, agreement or other instrument and the provisions of this Agreement, the provisions of this Agreement shall control. The obligation of any Issuing Bank to make any amendment, modification or supplement to any Letter of Credit hereunder which increases the stated amount thereof shall be subject to the same conditions applicable under this Section 2.2 (including the conditions set forth in Section 3.2) to the issuance of new Letters of Credit, and no Issuing Bank shall be obligated to make any such amendment, modification or supplement unless the Letter of Credit affected thereby would have complied with such conditions had it originally been issued hereunder, on the date of such amendment, modification or supplement, in such amended, modified or supplemented form. The obligation of any Issuing Bank to add any letter of credit hereto as contemplated by Section 2.2(a)(2) shall be subject to the same conditions applicable under this Section 2.2 (including the conditions set forth in Section 3.2) to the issuance of new Letters of Credit, and no Issuing Bank shall be obligated to make any such addition unless the Added Letter of Credit would have complied with such conditions had it originally been issued hereunder on the date of such addition. In the event of any conflict between any application, agreement or other instrument relating to an Added Letter of Credit and the provisions of this Agreement, the provisions of this Agreement shall control.

     (h) Interest Payable to Issuing Banks by Banks. To the extent that any Bank shall fail to pay any amount required to be paid pursuant to Sections 2.2(d) or (e) on the due date therefor, such Bank shall pay interest to the Issuing Bank owed such amount (through the Agent) on such amount from and including such due date to but excluding the date such payment is made at a rate per annum equal to the Federal Funds Rate.

     (i) Indemnification of the Banks, Issuing Banks and Agent. The Borrowers hereby indemnify and hold harmless each Bank, each Issuing Bank and the Agent from and against any and all claims, damages, losses, liabilities, costs, fees and expenses that such Bank, such Issuing Bank or the Agent may incur (or that may be claimed against such Bank, such Issuing Bank or the Agent by any Person whatsoever) by reason of or in connection with the execution and delivery or transfer of or payment or refusal to pay by each Issuing Bank under any Letter of Credit (EXPRESSLY INCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, FEE OR EXPENSE ATTRIBUTABLE TO THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OF SUCH BANK, SUCH ISSUING BANK OR THE AGENT, AS THE CASE MAY BE, BUT EXCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, FEE OR EXPENSE ATTRIBUTABLE TO THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH BANK, SUCH ISSUING BANK OR THE AGENT, AS THE CASE MAY BE).

only to the extent, caused by (A) in the case of each Issuing Bank, the willful misconduct or gross negligence of such Issuing Bank in determining whether a request presented under any Letter of Credit complied with the terms of such Letter of Credit or (B) in the case of any Bank, such Bank’s failure to pay its Letter of Credit Liabilities pursuant to Sections 2.2(d), (e) and (h).

     (j) Existing Letters of Credit. For the avoidance of doubt, the parties hereto acknowledge and agree that all Existing Letters of Credit are deemed to be issued under this Agreement by the Issuing Bank party thereto at the request of TWC and shall constitute Letters of Credit hereunder for all purposes (including Section 2.2(b) and Section 2.2(d)), and no notice requesting issuance thereof shall be required hereunder. Each reference herein to the issuance of a Letter of Credit shall include any such deemed issuance. All fees accrued on the Existing Letters of Credit to but excluding the date hereof shall be for the account of the relevant “Issuing Bank” and the “Banks” (as those terms are used in the 2005 Credit Agreement) as provided in the 2005 Credit Agreement, and all fees accruing on the Existing Letters of Credit on and after the date hereof shall be for the account of the relevant Issuing Bank thereof and the Banks as provided herein.

     (k) Cash Collateral.

     (l) Applicability of ISP98 (ICC Publication No. 59). Unless otherwise expressly agreed by an Issuing Bank and a Borrower when a Letter of Credit is issued or except as otherwise specifically provided in respect of an Existing Letter of Credit or an Added Letter of Credit, the rules of the “International Standby Practices 1998” published by the Institute of International Banking Law & Practice, Inc. (or such later version thereof as may be in effect at the time of issuance) shall apply to each Letter of Credit.

     (m) Added Letters of Credit.

     SECTION 2.3. Making the Revolving Credit Advances.

     (a) Each Revolving Credit Borrowing shall be made on notice, given not later than 11:00 a.m. (New York City time) on the third Business Day prior to the date of the proposed Revolving Credit

Borrowing in the case of a Revolving Credit Borrowing consisting of Eurodollar Rate Advances, or 10:00 a.m. (New York City time) on the Business Day of the proposed Revolving Credit Borrowing in the case of a Revolving Credit Borrowing consisting of Base Rate Advances, by the Borrower requesting such Revolving Credit Borrowing to the Agent, which shall give to each Bank prompt notice thereof. Each such notice of a Revolving Credit Borrowing (a “Notice of Revolving Credit Borrowing”) shall be by telephone, confirmed immediately in writing, or telecopier in substantially the form of Exhibit D-2 hereto, specifying therein the requested (i) date of such Revolving Credit Borrowing, (ii) Type of Revolving Credit Advances, (iii) aggregate amount of such Revolving Credit Borrowing, and (iv) in the case of a Revolving Credit Borrowing consisting of Eurodollar Rate Advances, initial Interest Period for each such Revolving Credit Advance. Each Bank shall, before 12:00 p.m. (New York City time) on the date of such Revolving Credit Borrowing, make available for the account of its Applicable Lending Office to the Agent at its address referred to in Section 8.2 (excluding, for such purpose, any address to which copies are to be sent), in same day funds, such Bank’s ratable portion of such Revolving Credit Borrowing. After the Agent’s receipt of such funds, the Agent will make such funds available to the Borrower requesting such Revolving Credit Borrowing at such address; provided that the Agent shall not be required to make such funds available if the applicable conditions set forth in Section 3.2 have not been fulfilled.

     (b) Anything in Section 2.3(a) to the contrary notwithstanding, a Borrower may not select Eurodollar Rate Advances for any Revolving Credit Borrowing if the obligation of the Banks to make Eurodollar Rate Advances shall then be suspended pursuant to Sections 2.3(e), 2.14 or 2.16.

     (c) No Borrower may select Eurodollar Rate Advances for any Revolving Credit Borrowing if the aggregate amount of such Revolving Credit Borrowings is less than $5,000,000.

     (d) Each Notice of Revolving Credit Borrowing shall be irrevocable and binding on the Borrower delivering such notice. In the case of any Revolving Credit Borrowing that the related Notice of Revolving Credit Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower requesting such Borrowing shall indemnify each Bank against any loss, cost or expense incurred by such Bank as a result of any failure by such Borrower to fulfill on or before the date specified in such Notice of Revolving Credit Borrowing for such Revolving Credit Borrowing the applicable conditions set forth in Article III or as a result of a cancellation pursuant to Section 2.3(f), including any loss (excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Bank to fund the Revolving Credit Advance to be made by such Bank as part of such Revolving Credit Borrowing when such Revolving Credit Advance, as a result of such failure or cancellation, is not made on such date.

     (e) If the Agent is unable to determine the Eurodollar Rate for Eurodollar Rate Advances, the obligation of the Banks to make, or to Convert Revolving Credit Advances into, Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrowers and the Banks that the circumstances causing such suspension no longer exist, and, except as provided in Section 2.3(f), each Revolving Credit Advance comprising any requested Revolving Credit Borrowing shall be a Base Rate Advance.

     (f) If a Borrower has requested a proposed Revolving Credit Borrowing consisting of Eurodollar Rate Advances and as a result of circumstances referred to in Section 2.3(e), Section 2.14(b) or Section 2.16 such Revolving Credit Borrowing would not consist of Eurodollar Rate Advances, such Borrower may, by notice given not later than 3:00 p.m. (New York City time) at least one Business Day prior to the date such proposed Revolving Credit Borrowing would otherwise be made, cancel such Revolving Credit Borrowing, in which case such Revolving Credit Borrowing shall be cancelled and no Revolving Credit Advances shall be made as a result of such requested Revolving Credit Borrowing, but

such Borrower shall indemnify the Banks in connection with such cancellation as contemplated by Section 2.3(d).

     (g) Unless the Agent shall have received notice from a Bank prior to the date of any Revolving Credit Borrowing that such Bank will not make available to the Agent such Bank’s ratable portion of such Revolving Credit Borrowing, the Agent may assume that such Bank has made such portion available to the Agent on the date of such Revolving Credit Borrowing in accordance with Section 2.3(a) and the Agent may, in reliance upon such assumption, make available to a Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have so made such ratable portion available to the Agent, such Bank and Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to such Borrower until the date such amount is repaid to the Agent, at (i) in the case of such Borrower, the interest rate applicable at the time to Revolving Credit Advances comprising such Revolving Credit Borrowing and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Bank’s Revolving Credit Advance as part of such Revolving Credit Borrowing for purposes of this Agreement and such Borrower shall be relieved of its obligations to repay on demand such amount under this Section 2.3(g).

     (h) The failure of any Bank to make the Revolving Credit Advance to be made by it as part of any Revolving Credit Borrowing shall not relieve any other Bank of its obligation, if any, hereunder to make its Revolving Credit Advance on the date of such Revolving Credit Borrowing, but no Bank shall be responsible for the failure of any other Bank to make any Revolving Credit Advance to be made by such other Bank.

     SECTION 2.4. Reduction of the Commitments. Each Borrower shall have the right, upon at least three Business Days notice to the Agent, to terminate in whole or reduce ratably in part (i) the Unused Revolving Credit Commitments for such Borrower and (ii) the unused portions of the Letter of Credit Commitments; provided that each partial reduction shall be in the aggregate amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof and shall be made ratably among the Banks or Issuing Banks, as the case may be, in accordance with their respective Revolving Credit Commitments for such Borrower or Letter of Credit Commitments, as the case may be, and provided further that the amount of the Letter of Credit Commitment of any Issuing Bank shall not be reduced to an amount which is less than the aggregate amount of all Letter of Credit Liabilities in respect of all Letters of Credit issued or deemed issued by such Issuing Bank; and provided further that the Revolving Credit Commitments for TWC shall not be reduced to an amount which is less than the greatest, for any Borrower, of the sum of (i) the aggregate outstanding principal amount of Revolving Credit Advances owed by such Borrower plus (ii) the aggregate amount of all Letter of Credit Liabilities in respect of Letters of Credit issued at the request of such Borrower; and provided further that the Revolving Credit Commitments for any Borrower shall not be reduced to an amount which is less than the sum of (i) the aggregate outstanding principal amount of Revolving Credit Advances owed by such Borrower plus (ii) the aggregate amount of all Letter of Credit Liabilities in respect of Letters of Credit issued at the request of such Borrower; and provided further that the Revolving Credit Commitments for TWC shall not be reduced to an amount which is less than the aggregate amount of the Letter of Credit Commitments. Each termination or reduction of any Commitment shall be permanent. Upon the termination of the Revolving Credit Commitments for MLP, the termination of all Letters of Credit issued at the request of MLP and the final repayment of all Obligations owing by MLP, the TWC Guaranty shall be deemed to be automatically released, subject, however, to reinstatement as contemplated by Section 4.02(b) of the Guaranty and except that the TWC Guaranty shall continue in full force and effect as to all agreements and obligations of MLP that by the terms hereof survive the payment in full of principal and interest.

     SECTION 2.5. Prepayments.

     (a) Each Borrower may, upon notice to the Agent, (i) before 10:00 a.m. (New York City time) for Base Rate Advances on the date of prepayment and (ii) upon at least two Business Days’ notice to the Agent for Eurodollar Rate Advances, stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given such Borrower shall, prepay the outstanding principal amount of the Revolving Credit Advances comprising part of the same Revolving Credit Borrowing in whole or ratably in part, together with accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 8.4(c) as a result of such prepayment; provided that each prepayment pursuant to this Section 2.5(a) shall be in an aggregate principal amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof.

     (b) Additionally, if at any date the sum of the aggregate amount of all Revolving Credit Advances owed to any Bank by any Borrower plus the aggregate amount of all Letter of Credit Liabilities held by such Bank for all Letters of Credit issued at the request of such Borrower exceeds such Bank’s Revolving Credit Commitment for such Borrower at such date, such Borrower shall, on such date, ratably repay the Revolving Credit Advances owed by such Borrower in a principal amount necessary so that (after giving effect to such repayment) the sum, for each Bank, of the aggregate amount of all Revolving Credit Advances owed to such Bank by such Borrower plus the aggregate amount of all Letter of Credit Liabilities held by such Bank for all Letters of Credit issued at the request of such Borrower does not exceed such Bank’s Revolving Credit Commitment for such Borrower at such date.

     (c) At the time of each payment pursuant to Section 2.5(b) by a Borrower, such Borrower shall also pay accrued interest to the date of such payment on the principal amount paid and amounts, if any, required to be paid pursuant to Section 8.4(c) as a result of such payment. To the extent that any amount would be required hereunder to be applied to Revolving Credit Advances owed by any Borrower but for the fact that no Revolving Credit Advances to such Borrower remain outstanding, such Borrower will cause such amount first, to be paid on any outstanding unreimbursed drawings under Letters of Credit issued at the request of such Borrower and, second to be deposited in an LC Cash Collateral Account in respect of such Borrower.

     (d) All amounts received by the Agent pursuant to any Security Document shall be applied first, to reimburse the Agent for all costs, fees, expenses and other amounts to the extent provided in such Security Document, second, to ratably pay the principal of and interest of the Revolving Credit Advances and unpaid drawings under Letters of Credit, third to ratably pay all other Obligations, and fourth to be deposited in one or more LC Cash Collateral Accounts to the extent any Letters of Credit are outstanding.

     SECTION 2.6. Increased Costs.

     (a) If any Bank or Issuing Bank determines that (i) the introduction of or any change in or in the interpretation, application or applicability of any law or regulation or (ii) the compliance with any guideline issued or request made by any central bank or other governmental or monetary authority (whether or not having the force of law), in each case introduced, changed, issued or made after the Effective Date (in the case of each Bank or Issuing Bank which was a party to this Agreement on the Effective Date) or after the effective date of the relevant document (a Transfer Agreement or this Agreement) pursuant to which a Person becomes a Bank or an Issuing Bank (in the case of each other Bank or Issuing Bank), affects or would affect the amount of capital required or expected to be maintained by such Bank or Issuing Bank, as the case may be, or any corporation controlling such Bank or Issuing Bank, as the case may be, and that the amount of such capital is increased by or based upon the existence of such Bank’s or such Issuing Bank’s, as the case may be, commitment to lend hereunder, issue Letters of Credit or purchase participations in Letters of Credit and other commitments of this type, then,

upon demand by such Bank or Issuing Bank, as the case may be (with a copy of such demand and related certificate (which certificate shall specify in reasonable detail the nature of such change in capital requirements, the proposed (or actual) compliance change to be adopted by the applicable Bank or Issuing Bank and the calculations upon which any compensation is claimed hereunder) to the Agent), the Borrowers shall pay to the Agent within five Business Days of receipt of such demand for the account of such Bank or Issuing Bank, as the case may be, from time to time as specified by such Bank or Issuing Bank, as the case may be, additional amounts sufficient to compensate such Bank or Issuing Bank, as the case may be, or such corporation in the light of such circumstances, to the extent that such Bank or Issuing Bank, as the case may be, reasonably determines such increase in capital to be allocable to the existence of such Bank’s or such Issuing Bank’s, as the case may be, commitment to lend, issue Letters of Credit or purchase participations in Letters of Credit hereunder. A certificate as to the amount of such additional amounts, submitted to the Borrower that is obligated to pay such amount and the Agent by such Bank or Issuing Bank, as the case may be, shall be prima facie evidence of the amount of such additional amounts absent manifest error. No Bank or Issuing Bank shall have any right to recover any additional amounts from a Borrower under this Section 2.6(a) for any period more than 90 days prior to the date such Bank or Issuing Bank, as the case may be, notifies such Borrower of any such introduction, change or compliance.

     (b) If, due to either (i) the introduction of or any change (other than any change by way of imposition or increase of reserve requirements included in the Eurodollar Rate Reserve Percentage) in or in the interpretation, application or applicability of any law or regulation or (ii) the compliance with any guideline issued or request made by any central bank or other governmental or monetary authority (whether or not having the force of law), in each case introduced, changed, issued or made after the Effective Date (in the case of each Bank which was a party to this Agreement on the Effective Date) or after the effective date of the relevant document (a Transfer Agreement or this Agreement) pursuant to which a Person becomes a Bank (in case of each other Bank), there shall be any increase in the cost to any Bank of agreeing to make or making, funding or maintaining Eurodollar Rate Advances to any Borrower, from that in effect at the Effective Date or at the date of such relevant document, as the case may be, then such Borrower shall from time to time, upon demand by such Bank (with a copy of such demand to the Agent), pay to the Agent for the account of such Bank additional amounts sufficient to compensate such Bank for such increased cost. A certificate as to the amount of such increased cost, submitted to such Borrower and the Agent by such Bank, shall be prima facie evidence of the amount of such increased cost absent manifest error. No Bank shall have the right to recover any such increased costs for any period more than 90 days prior to the date such Bank notifies such Borrower of any such introduction, change, compliance or proposed compliance.

     (c) In the event that any Bank (other than a Bank that is also an Issuing Bank) (i) makes a demand for payment under Section 2.8 or 2.17 or this Section 2.6, or (ii) does not agree to provide its consent or agree to any amendment or waiver pursuant to Section 8.1 where such consent or agreement to provide an amendment or waiver is required of all the Banks hereto, TWC may within 90 days of such demand or non-consent, if no Default or Event of Default then exists, replace such Bank with another commercial bank in accordance with all of the provisions of the second and third sentences of Section 8.5(a), and clauses (b) and (d) of Section 8.5 (including execution of an appropriate Transfer Agreement); provided that (v) all obligations of such Bank to lend hereunder or purchase participations in Letters of Credit shall be terminated and the Letter of Credit Interests held by such Bank and Notes payable to such Bank and all other obligations owed to such Bank hereunder shall be purchased in full without recourse at par plus accrued interest and fees at or prior to such replacement, (w) such replacement bank shall be an Eligible Assignee, (x) such replacement bank shall, from and after such replacement, be deemed for all purposes to be a “Bank” hereunder with a Revolving Credit Commitment for each Borrower and Letter of Credit Liabilities in the amount of the Revolving Credit Commitment for each Borrower and Letter of Credit Liabilities of such Bank being replaced, immediately prior to such replacement (plus, if such

replacement bank is already a Bank prior to such replacement the respective Revolving Credit Commitments for each Borrower and Letter of Credit Liabilities of such Bank prior to such replacement), as such amount may be changed from time to time pursuant hereto, and shall have all of the rights, duties and obligations hereunder of the Bank being replaced, including obligations under Section 2.2, (y) such other actions shall be taken by the Borrowers, such Bank and such replacement bank as may be appropriate to effect the replacement of such Bank with such replacement bank on terms such that such replacement bank has all of the rights, duties and obligations hereunder as such Bank (including specification of the information contemplated by Schedule I as to such replacement bank), and (z) no Bank or Issuing Bank shall be required to increase any Commitment it may have or to replace such Bank being replaced.

     (d) Before making any demand under this Section 2.6, each Bank agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Applicable Lending Office if the making of such a designation would avoid the need for, or reduce the amount of, such increased cost and would not, in the reasonable judgment of such Bank, be otherwise disadvantageous to such Bank.

     SECTION 2.7. Payments and Computations.

     (a) Each Borrower shall make each payment hereunder to be made by it not later than 11:00 a.m. (New York City time) on the day when due in Dollars to the Agent at its address referred to in Section 8.2 (excluding, for such purpose, any address to which copies are to be sent), in each case in same day funds, without deduction, counterclaim or offset of any kind. The Agent will promptly thereafter cause to be distributed to the Banks like funds relating to the payment of principal, interest or any fees payable to the Banks for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Bank or Issuing Bank to such Bank or Issuing Bank, as the case may be, for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. In no event shall any Bank be entitled to share any fee paid to the Agent pursuant to Section 2.11(a), any other fee paid to the Agent, as such, any amount applied to reimburse the Agent as contemplated by Section 2.2(k), Section 2.5(d), Section 6.2 or any other provision of any Credit Document or any Fronting Fee, other fee, cost or charge paid to an Issuing Bank pursuant to Section 2.11(b)(i).

     (b) (i) All computations of interest based on clause (a) of the definition herein of “Base Rate” shall be made by the Agent on the basis of a year of 365 or 366 days, as the case may be, and (ii) all computations of Letter of Credit Fees, Commitment Fees, Fronting Fees and all other fees and of interest based on the Eurodollar Rate or the Federal Funds Rate and interest pursuant to Section 2.17 shall be made by the Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest, Letter of Credit Fees, Commitment Fees, Fronting Fees or other fees are payable. Each determination by the Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error.

     (c) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest, Commitment Fee, Letter of Credit Fee, Fronting Fee or any other fee hereunder, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

     (d) Unless the Agent shall have received notice from a Borrower prior to the date on which any payment is due by such Borrower to any Bank hereunder that such Borrower will not make such payment in full, the Agent may assume that such Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank hereunder. If and to the extent such Borrower shall not have so made such payment in full to the Agent, each Bank shall repay to the Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Agent, at the Federal Funds Rate.

     SECTION 2.8. Taxes.

     (a) Any and all payments by any Borrower hereunder shall be made, in accordance with Section 2.7, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings with respect thereto, and all liabilities with respect thereto, excluding in the case of each Bank, each Issuing Bank and the Agent, (i) taxes imposed on its net income or net profits, and franchise taxes imposed on it, by the jurisdiction under the laws of which such Bank, such Issuing Bank or the Agent (as the case may be) is organized or any political subdivision thereof and (ii) taxes imposed as a result of a present or former connection between such Bank, such Issuing Bank or the Agent, as the case may be, and the jurisdiction imposing such tax or any political subdivision thereof (other than any such connection arising solely from such Bank, such Issuing Bank or the Agent, as the case may be, having executed or delivered, or performed its obligations or received a payment under, or taken any other action related to any Credit Document) and, in the case of each Bank, taxes imposed on its net income or net profits, and franchise taxes imposed on it, by the jurisdiction of such Bank’s Applicable Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If any Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note to any Bank, any Issuing Bank or the Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions for Taxes (including deductions for Taxes applicable to additional sums payable under this Section 2.8), such Bank, such Issuing Bank or the Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions for Taxes been made, (ii) such Borrower shall make such deductions and (iii) such Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

     (b) In addition, each Borrower agrees to pay all present or future filing or recording fees, stamp or documentary taxes and all other excise or property taxes, charges or similar levies which arise from any payment made by such Borrower hereunder or from the execution, delivery, filing, recording or registration of, or otherwise with respect to, any Credit Document (herein referred to as “Other Taxes”).

     (c) Each Borrower will indemnify each Bank, each Issuing Bank and the Agent for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.8) owed and paid by such Bank, such Issuing Bank or the Agent, as the case may be, and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within 30 days from the date such Bank, such Issuing Bank or the Agent, as the case may be, makes written demand therefor; provided that such Borrower shall have no liability pursuant to this clause (c) of this Section 2.8 to indemnify a Bank, an Issuing Bank or the Agent for Taxes or Other Taxes which were paid by such Bank, such Issuing Bank or the Agent, as the case may be, more than ninety days prior to such written demand for indemnification.

     (d) In the event that a Bank, an Issuing Bank or the Agent receives a written communication from any governmental authority with respect to an assessment or proposed assessment of any Taxes, such Bank, such Issuing Bank or Agent, as the case may be, shall promptly notify TWC in writing and provide TWC with a copy of such communication. The Agent’s, an Issuing Bank’s or a Bank’s failure to provide a copy of such communication to TWC shall not relieve TWC of any of its obligations hereunder.

     (e) Promptly following payment of Taxes by or at the direction of any Borrower, such Borrower will furnish to the Agent, at its address referred to in Section 8.2, the original or a certified copy of a receipt evidencing payment thereof (or, if no such receipt is reasonably available, other evidence of payment reasonably acceptable to the Agent). Should any Bank, any Issuing Bank or the Agent ever receive any refund, credit or deduction from any taxing authority to which such Bank, such Issuing Bank or the Agent, as the case may be, would not be entitled but for the payment by such Borrower of Taxes or Other Taxes as required by this Section 2.8 (it being understood that the decision as to whether or not to claim, and if claimed, as to the amount of any such refund, credit or deduction shall be made by such Bank, such Issuing Bank or the Agent, as the case may be, in its reasonable judgment), such Bank, such Issuing Bank or the Agent, as the case may be, thereupon shall repay to such Borrower an amount with respect to such refund, credit or deduction equal to any net reduction in taxes actually obtained by such Bank, such Issuing Bank or the Agent, as the case may be, and determined by such Bank, such Issuing Bank or the Agent, as the case may be, to be attributable to such refund, credit or deduction.

     (f) Each Bank organized under the laws of a jurisdiction outside the United States shall on or prior to the date of its execution and delivery of this Agreement in the case of each Bank which is a party to this Agreement on the date this Agreement becomes effective and on the date the Transfer Agreement pursuant to which it becomes a Bank is first effective in the case of each other Bank, and from time to time thereafter as necessary or appropriate (but only so long thereafter as such Bank remains lawfully able to do so), provide the Agent and each Borrower with two original Internal Revenue Service Forms W-8BEN or W-8ECI (or, in the case of a Bank that has provided a certificate to the Agent that it is not (i) a “bank” as that term is used in Section 881(c)(3)(A) of the Code, (ii) a ten-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of such Borrower or (iii) a controlled foreign corporation related to such Borrower (within the meaning of Section 864(d)(4) of the Code), Internal Revenue Service Forms W-8BEN), or any successor or other form prescribed by the Internal Revenue Service, certifying that such Bank is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement or any other Credit Document or, in the case of a Bank that has certified that it is not a “bank” as described above, certifying that such Bank is a foreign corporation. If the forms provided by a Bank at the time such Bank first becomes a party to this Agreement indicate a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes unless and until such Bank provides the appropriate forms certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Taxes for periods governed by such forms.

     (g) For any period with respect to which a Bank has failed to provide any Borrower with the appropriate form, certificate or other document required by subsection (f) of this Section 2.8 (other than if such failure is due to a change in the applicable law, or in the interpretation or application thereof, occurring after the date on which a form, certificate or other document originally was required to be provided) such Bank shall not be entitled to indemnification under subsection (a) or (c) of this Section 2.8 with respect to Taxes imposed by the United States by reason of such failure; provided, however, that should a Bank become subject to Taxes because of its failure to deliver a form, certificate or other document required hereunder, the Borrowers shall take such steps as such Bank shall reasonably request (at such Bank’s expense) to assist such Bank in recovering such Taxes.

     (h) Any Bank claiming any additional amounts payable pursuant to this Section 2.8 agrees to use reasonable efforts to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of such Bank, be otherwise materially disadvantageous to such Bank.

     (i) If a Borrower determines in good faith that a reasonable basis exists for contesting a Tax, the relevant Bank, or the Agent, as applicable, shall provide reasonable cooperation to such Borrower in challenging such Tax at such Borrower’s expense and if requested by such Borrower in writing; provided, however, that no Bank nor the Agent, as applicable, shall be required to take any action hereunder which, in the reasonable discretion of such Bank or the Agent, as applicable, would cause such Bank or its Applicable Lending Office or the Agent, as applicable, to suffer a legal, regulatory or material economic disadvantage.

     (j) Without prejudice to the survival of any other agreement of the Borrowers hereunder, the agreements and obligations of the Borrowers contained in this Section 2.8 shall survive the payment in full of principal and interest hereunder and the Termination Date.

     (k) Notwithstanding any provision of this Agreement or the Notes to the contrary, this Section 2.8 shall be the sole provision governing indemnities for and claims for Taxes under this Agreement.

     (l) Notwithstanding any other provision in this Section 2.8, no additional amount shall be required to be paid by any Borrower under Section 2.8(a) or 2.8(c) to any Bank organized under the laws of a jurisdiction outside the United States in respect of Taxes or any liabilities (including penalties, interest and expenses arising therefrom or with respect thereto), except to the extent that any change after the Effective Date (in the case of each Bank which was a party to this Agreement on the Effective Date) or after the effective date of the relevant document (a Transfer Agreement or this Agreement) pursuant to which a Person becomes a Bank (in case of each other Bank) in any such requirement for a deduction, withholding or payment of Taxes described in this Section 2.8 shall result in an increase in the rate of such deduction, withholding or payment from that in effect at the Effective Date (in the case of each Bank which was a party to this Agreement on the Effective Date) or at the date of such relevant document (in the case of each other Bank). For avoidance of doubt, this Section 2.8(l) does not apply to Other Taxes.

     SECTION 2.9. Sharing of Payments, Etc. If any Bank shall obtain any payment (whether voluntary or involuntary, or through the exercise of any right of set-off or otherwise) on account of the Revolving Credit Advances owed to it or its Letter of Credit Interest (other than pursuant to Section 2.6, 2.8, 2.17, 8.4(b) or 8.4(c)) in excess of its ratable share of payments on account of all Revolving Credit Advances and Letter of Credit Interests obtained by all the Banks, such Bank shall forthwith purchase from the other Banks such participations in the Revolving Credit Advances and Letter of Credit Interests of such other Banks as shall be necessary to cause such purchasing Bank to share the excess payment ratably with each of them; provided that if all or any portion of such excess payment is thereafter recovered from such purchasing Bank, such purchase from each Bank shall be rescinded and such Bank shall repay to the purchasing Bank the purchase price to the extent of such Bank’s ratable share (according to the proportion of (i) the amount of the participation purchased from such Bank as a result of such excess payment to (ii) the total amount of such excess payment) of such recovery together with an amount equal to such Bank’s ratable share (according to the proportion of (i) the amount of such Bank’s required repayment to (ii) the total amount so recovered from the purchasing Bank) of any interest or other amount paid or payable by the purchasing Bank in respect of the total amount so recovered. Each Borrower agrees that any Bank so purchasing a participation from another Bank pursuant to this Section 2.9 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with

respect to such participation as fully as if such Bank were the direct creditor of such Borrower in the amount of such participation. For avoidance of doubt, in no event shall the Borrowers be liable for duplicative payments under this Section 2.9 in respect of any Obligations.

     SECTION 2.10. Evidence of Debt. (a) Each Bank and Issuing Bank shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of each Borrower to such Bank or Issuing Bank resulting from each Revolving Credit Advance or Letter of Credit Interest owing to such Bank or Issuing Bank, as the case may be, from time to time, including the amounts of principal and interest payable and paid to such Bank or Issuing Bank from time to time hereunder. Each Borrower agrees that upon notice by any Bank to such Borrower (with a copy of such notice to the Agent) to the effect that a promissory note or other evidence of indebtedness is required or appropriate in order for such Bank to evidence (whether for purposes of pledge, enforcement or otherwise) the Revolving Credit Advances to such Borrower owing to, or to be made by, such Bank, such Borrower shall promptly execute and deliver to such Bank, with a copy to the Agent, a Note in substantially the form of Exhibit G hereto payable to the order of such Bank. All references to Notes in the Credit Documents shall mean Notes, if any, to the extent issued hereunder.

     (a) In addition to the entries contemplated by Section 8.5(c), the Register maintained by the Agent shall set forth (i) the date and amount of each Letter of Credit and Revolving Credit Borrowing made hereunder, the Type of Revolving Credit Advances comprising such Revolving Credit Borrowing and, if appropriate, the Interest Period applicable thereto, and (ii) the amount of any interest due and payable from each Borrower to each Bank hereunder.

     (b) Entries made in good faith by the Agent in the Register pursuant to subsection (b) above, and by each Bank or Issuing Bank in its account or accounts pursuant to subsection (a) above, shall be prima facie evidence of the matters set forth therein, absent manifest error; provided, however that the failure of the Agent or such Bank or Issuing Bank to make an entry, or any finding that an entry is incorrect, in the Register or such account or accounts shall not limit or otherwise affect the obligations of any Credit Party under any Credit Document.

     SECTION 2.11. Fees.

     (a) Agent’s Fees. TWC agrees to pay to the Agent, for its sole account, such fees as may be separately agreed to in writing by TWC and the Agent.

     (b) Letter of Credit Fees.

          (i) Fronting Fee and Other Fees and Charges of Issuing Banks. Each Borrower agrees to pay to the Agent for the account of each Issuing Bank a fronting fee (a “Fronting Fee”) based on the Available Amount of each Letter of Credit issued at the request of such Borrower (for the stated duration thereof) issued by such Issuing Bank in an amount equal to 0.15% per annum. All Fronting Fees payable pursuant to this Section 2.11(b)(i) shall be payable in arrears for each Fiscal Quarter on the first Business Day following the end of such Fiscal Quarter, on the Termination Date and on demand from time to time during the continuance of an Event of Default. In addition, each Borrower shall pay directly to each Issuing Bank for its own account the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of such Issuing Bank relating to Letters of Credit issued at the request of such Borrower as from time to time in effect. Such customary fees and standard costs and charges are due and payable on demand and are nonrefundable.

          (ii) Participating Banks. Each Borrower agrees to pay to the Agent for the account of each Bank a letter of credit fee (a “Letter of Credit Fee”) based on such Bank’s LC Participation

Percentage of the average daily aggregate Available Amount of all Letters of Credit issued at the request of such Borrower outstanding from time to time at a rate per annum equal from time to time to the Applicable Margin for Eurodollar Rate Advances for such Borrower in effect from time to time (for the stated duration thereof).

All amounts payable pursuant to this Section 2.11(c) shall be paid in arrears on the last Business Day of each Fiscal Quarter and on the Termination Date.

     SECTION 2.12. Repayment of Revolving Credit Advances.

     SECTION 2.13. Interest.

     (a) Scheduled Interest. Each Borrower shall pay interest on the unpaid principal amount of each Revolving Credit Advance made to such Borrower from the date of such Revolving Credit Advance until such principal amount shall be paid in full, at the following rates per annum:

          (i) Base Rate Advances. During such periods as such Revolving Credit Advance is a Base Rate Advance, a rate per annum equal at all times to the sum of (x) the Base Rate in effect from time to time plus (y) the Applicable Margin in effect from time to time for such Borrower as to Base Rate Advances, payable in arrears quarterly on the last Business Day of each Fiscal Quarter during such periods and on the date such Base Rate Advance shall be Converted or paid in full.

     SECTION 2.14. Interest Rate Determination.

     (a) The Agent shall give prompt notice to the Borrowers and the Banks of the applicable interest rate determined by the Agent for purposes of Section 2.13(a)(i) or 2.13(a)(ii).

     (b) If, with respect to any Eurodollar Rate Advances, the Majority Banks notify the Agent that either (1) the Eurodollar Rate for any Interest Period for such Eurodollar Rate Advances will not adequately reflect the cost to such Majority Banks of making, funding or maintaining their respective Eurodollar Rate Advances for such Interest Period, or (2) Dollar deposits for the relevant amounts and Interest Period for their respective Eurodollar Rate Advances are not available to them in the London interbank market, the Agent shall forthwith so notify the Borrowers and the Banks, whereupon (i) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance, and (ii) the obligation of the Banks to make, or to Convert Revolving Credit Advances into, Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrowers and the Banks that the circumstances causing such suspension no longer exist.

     (c) If a Borrower shall fail to select the duration of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01, the Agent will forthwith so notify such Borrower and the Banks and such Revolving Credit Advances will automatically, on the last day of the then existing Interest Period therefor, Convert into Base Rate Advances.

     (d) On the date on which the aggregate unpaid principal amount of Eurodollar Rate Advances comprising any Revolving Credit Borrowing shall be reduced, by payment or prepayment or otherwise, to less than $5,000,000, such Revolving Credit Advances shall automatically Convert into Base Rate Advances and the applicable Borrower shall pay any amounts required to be paid pursuant Section 8.4(c) as a result of such Conversion.

     (e) If any Event of Default exists as to any Borrower, (i) each Eurodollar Rate Advance made to such Borrower will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the Banks to make Eurodollar Rate Advances to such Borrower, and to Convert Advances made to such Borrower into Eurodollar Rate Advances, shall be suspended.

     SECTION 2.15. Optional Conversion of Revolving Credit Advances. Any Borrower may on any Business Day, upon notice given to the Agent not later than 11:00 a.m. (New York City time) on the third Business Day prior to the date of the proposed Conversion and subject to the provisions of Sections 2.14 and 2.16, Convert all Revolving Credit Advances of one Type comprising the same Revolving Credit Borrowing made to such Borrower into Revolving Credit Advances of the other Type; provided, however, that any Conversion of Eurodollar Rate Advances into Base Rate Advances shall be made only on the last day of an Interest Period for such Eurodollar Rate Advances and any Conversion of Base Rate Advances into Eurodollar Rate Advances shall be in an amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof. Each such notice of a Conversion shall, within the restrictions specified above, specify (a) the date of such Conversion, (b) the Revolving Credit Advances to be Converted and (c) if such Conversion is into Eurodollar Rate Advances, the duration of the initial Interest Period for each

such Revolving Credit Advance. Each notice of Conversion shall be irrevocable and binding on such Borrower.

     SECTION 2.16. Illegality. Notwithstanding any other provision of this Agreement, if any Bank shall notify the Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority having relevant jurisdiction asserts that it is unlawful, for any Bank or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, (a) each Eurodollar Rate Advance will automatically, upon such demand, Convert into a Base Rate Advance and (b) the obligation of the Banks to make Eurodollar Rate Advances or to Convert Revolving Credit Advances into Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrowers and the Banks that the circumstances causing such suspension no longer exist.

     SECTION 2.17. Additional Interest on Eurodollar Rate Advances. Each Borrower shall pay to each Bank, so long as such Bank shall be required under regulations of the Federal Reserve Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Eurodollar Rate Advance of such Bank to such Borrower, from the date of such Revolving Credit Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (a) the Eurodollar Rate for the Interest Period for such Revolving Credit Advance from (b) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Bank for such Interest Period, payable on each date on which interest is payable on such Revolving Credit Advance. Such additional interest shall be determined by such Bank and notified to such Borrower through the Agent. A certificate as to the amount of such additional interest submitted to such Borrower and the Agent by such Bank shall be conclusive and binding for all purposes, absent manifest error. No Bank shall have the right to recover any additional interest pursuant to this Section 2.17 for any period more than 90 days prior to the date such Bank notifies such Borrower that additional interest may be charged pursuant to this Section 2.17.

     SECTION 2.18. Nature of Obligations. Notwithstanding anything in this Agreement to the contrary, the respective obligations of the Borrowers under the Credit Documents are several and not joint. For avoidance of doubt, and without limitation of the preceding sentence, it is agreed that (i) no Borrower shall be liable for the Revolving Credit Advances (or interest or fees with respect thereto) made to a different Borrower under Section 2.1(a), and no Borrower shall be liable for the Reimbursement Obligations (or related fees) with respect to Letters of Credit issued at the request of a different Borrower pursuant to Section 2.1(b), (ii) with respect to each Borrower, the obligations set forth in Section 2.6(a) shall only apply in respect of the commitment of any Bank or Issuing Bank to lend to, or to issue (or purchase participations in) Letters of Credit issued at the request of, such Borrower, (iii) with respect to the indemnification obligations set forth in subsection 2.8(c), each Borrower shall only be responsible for such obligations that result from Taxes or Other Taxes in connection with Revolving Credit Advances made to, or Letters of Credit issued at the request of, or that otherwise pertain to, such Borrower or any of its Subsidiaries, (iv) with respect to any representation and warranty made by a Borrower pursuant to Section 3.2, such representation and warranty shall only be made by such Borrower as provided in clause (v) of this Section 2.18, (v) with respect to the representations and warranties made in Article IV or, if applicable, any other Credit Document, each Borrower makes such representations and warranties only with respect to, and only to the extent applicable to, such Borrower and its Subsidiaries, and (vi) with respect to covenants set forth in Article V, each Borrower is only responsible for compliance with such covenants only with respect to, and only to the extent applicable to, such Borrower and its Subsidiaries; provided that this Section 2.18 shall not limit or impair any Guaranty, any security agreement or any pledge delivered in order to comply with Section 6.2 or any Security Document. Furthermore, without limitation of the foregoing and notwithstanding anything in this Agreement or implied by law to the

contrary, the MLP shall have no obligation to cause any other Credit Party to take any action pursuant to this Agreement and shall have no responsibility for, or liability as a result of, any action taken by any other Credit Party pursuant to this Agreement, including without limitation, the indemnification obligations set forth in subsection 8.4(b), with respect to which the MLP shall only be responsible for such obligations that result from matters pertaining to or otherwise relating to the MLP or any of its Subsidiaries.

For the avoidance of doubt, Existing Assets shall cease to be considered subject to an Existing Asset Transaction if (x) with respect to clauses (i) and (ii) above, such Existing Assets cease to secure Non-Recourse Debt and (y) with respect to clause (iii) above, such Existing Assets have been transferred back to TWC or a Subsidiary of TWC (other than a Non-Recourse Subsidiary). Notwithstanding the foregoing, if Existing Assets that are subject to Existing Asset Transactions are transferred in connection with a foreclosure or in lieu of foreclosure upon Non-Recourse Debt, then they will be deemed to continue being subject to Existing Asset Transactions.

     (p) MLP Ownership of Credit Parties. In the case of TWC, permit MLP or any Subsidiary of MLP to own any direct or indirect interest in any Equity Interest in, or Hybrid Security issued by, any Credit Party (other than MLP).

     (q) Sale and Leaseback Transactions. Enter into, or permit any of its Subsidiaries to enter into, any Sale and Leaseback Transaction, if after giving effect thereto the sum of (i) the aggregate amount of all Attributable Obligations of such Borrower and its Subsidiaries plus (ii) the aggregate amount of all obligations of such Borrower and its Subsidiaries secured by any Lien referred to in paragraph (r) of Schedule IX-2 would exceed 3.5% of the Consolidated Net Tangible Assets (as defined in such paragraph (r)) of such Borrower.

(l) A Change of Control Event shall occur;

     then, and in any such event, the Agent while such event exists (i) shall at the request, or may with the consent, of the Majority Banks, by notice to the Borrowers, declare the Commitments of each Bank and of each Issuing Bank and the obligations of each Issuing Bank to issue any Letter of Credit and each Bank to make Revolving Credit Advances to be terminated, whereupon each Commitment and each such obligation shall forthwith terminate, and (ii) shall at the request, or may with the consent, of the Majority Banks, by notice to the Borrower as to which an Event of Default exists, declare the principal of the Reimbursement Obligations and Revolving Credit Advances owed by such Borrower, all interest thereon and all other amounts payable by such Borrower under this Agreement and any other Credit Document to be forthwith due and payable, whereupon all such amounts shall become and be forthwith due and payable, without requirement of any presentment, demand, protest, notice of intent to accelerate, further notice of acceleration or other further notice of any kind (other than the notice expressly provided for above), all of which are hereby expressly waived by the Borrowers; provided, however, that in the event of any Event of Default described in Section 6.1(e), (A) the Commitments of each Bank and of each Issuing Bank and the obligations of each Issuing Bank to issue a Letter of Credit and each Bank to make Revolving Credit Advances shall automatically be terminated and (B) the principal of the Reimbursement Obligations and Revolving Credit Advances, all such interest and all such other amounts shall automatically become and be due and payable, without presentment, demand, protest, notice of intent to accelerate, notice of acceleration or any other notice of any kind, all of which are hereby expressly waived by the Borrowers.

     SECTION 6.2. LC Cash Collateral Accounts. Upon the occurrence and during the continuance of any Event of Default that exists as to any Borrower (if the Agent has declared all amounts owed by such Borrower hereunder to be due and payable), such Borrower agrees that it shall forthwith, without any demand or the taking of any other action by any Issuing Bank, the Agent, or any of the Banks, provide cover for the outstanding Letter of Credit Liabilities in respect of Letters of Credit issued at the request of such Borrower by paying to the Agent immediately available funds in the amount equal to the then aggregate Available Amounts of all outstanding Letters of Credit issued at the request of such Borrower, which funds shall be deposited into a blocked deposit account or accounts to be established and

maintained at the office of Citibank (or an affiliate thereof) in the name of the Agent as collateral security for any outstanding Letter of Credit Liabilities in respect of Letters of Credit issued at the request of such Borrower (the “LC Cash Collateral Accounts” in respect of such Borrower). Each Borrower hereby pledges, and grants to the Agent for the ratable benefit of each Issuing Bank and the Banks, a security interest in all funds held in the LC Cash Collateral Accounts in respect of such Borrower from time to time and all proceeds thereof, as security for the payment of all Letter of Credit Liabilities in respect of Letters of Credit issued at the request of such Borrower. The Agent may from time to time withdraw funds then held in the LC Cash Collateral Accounts in respect of any Borrower and apply such funds to reimburse the Agent for all costs, fees, expenses and other amounts to the extent provided in the relevant Credit Document and, second, to the payment of any Reimbursement Obligations owing by such Borrower to any Issuing Bank as shall have become or shall become due and payable by such Borrower to such Issuing Bank under this Agreement in connection with the Letters of Credit issued at the request of such Borrower. The Agent shall exercise reasonable care in the custody and preservation of any funds held in the LC Cash Collateral Accounts and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that which the Agent accords its own property, it being understood that the Agent shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds or for investing such funds. If at any time (a) no Event of Default exists and (b) the funds in the LC Cash Collateral Accounts in respect of any Borrower deposited pursuant to this Section 6.2 exceed the aggregate amount of all Letter of Credit Liabilities in respect of Letters of Credit issued at the request of such Borrower, the Agent shall, upon request of such Borrower, return such excess to such Borrower. LC Cash Collateral Accounts may also be created as contemplated by Section 2.5(c) whether or not an Event of Default exists.

THE AGENT AND ISSUING BANKS

     SECTION 7.1. Agent’s Authorization and Action. Each of the Banks and Issuing Banks hereby appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers under this Agreement and the other Credit Documents as are delegated to the Agent by the terms hereof and thereof, together with such powers as are reasonably incidental thereto. As to any matters not expressly provided for by the Credit Documents (including enforcement of the terms of this Agreement or collection of the Reimbursement Obligations or Notes, fees and any other amounts due and payable pursuant to this Agreement), the Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority Banks, and such instructions shall be binding upon all Banks and all holders of Notes; provided, however, that the Agent shall not be required to take any action which exposes the Agent to personal liability or which is contrary to the Credit Documents or applicable law. The Agent agrees to give to each Bank prompt notice of each notice given to it by any Borrower pursuant to the terms of this Agreement or any other Credit Document. The Agent will promptly furnish to each Bank all items furnished to the Agent pursuant to Section 5.1(b).

     SECTION 7.2. Agent’s Reliance, Etc. Neither the Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by them or under or in connection with this Agreement, except for its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Agent: (i) may consult with legal counsel (including counsel for any Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (ii) makes no warranty or representation to any Bank or Issuing Bank and shall not be responsible to any Bank or Issuing Bank for any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement or any other

Without limiting the generality of the foregoing, insofar as the Agent is concerned, for purposes of determining compliance with any Credit Document (including Section 3.2 of this Agreement) with respect to any Revolving Credit Advance, each Bank shall be deemed to have consented to, approved and accepted and to be satisfied with each matter required under any Credit Document (including Section 3.2 of this Agreement), unless the officer of the Agent responsible for the transactions contemplated by the Credit Documents shall have received written notice from such Bank prior to such Revolving Credit Advance specifying its objection thereto and such Bank shall not have made available to the Agent any portion of such Revolving Credit Advance; provided that this sentence is solely for the benefit of the Agent (and not any Credit Party) and shall not amend, waive or otherwise modify Section 3.2, Section 6.1(b) or any other provision applicable to any Credit Party, whether in respect of such Revolving Credit Advance or any other Revolving Credit Advance or matter.

     SECTION 7.3. Issuing Banks’ Reliance, Etc. Neither the Issuing Banks nor any directors, officers, agents or employees of the Issuing Banks shall be liable for any action taken or omitted to be taken by any of them under or in connection with this Agreement, except for its or their own gross negligence or willful misconduct. The Issuing Banks shall not have, by reason of this Agreement a fiduciary relationship in respect of any Bank; and nothing in this Agreement, expressed or implied, is intended or shall be so construed as to impose upon the Issuing Banks any obligations in respect of this Agreement except as expressly set forth herein. Without limitation of the generality of the foregoing, each of the Issuing Banks: (i) may consult with legal counsel (including counsel for any Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (ii) makes no warranty or representation to any Bank or Issuing Bank and shall not be responsible to any Bank or Issuing Bank for any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement or any other Credit Document; (iii) shall not have any duty to ascertain or to inquire as to the satisfaction, performance or observance of any of the terms, covenants or conditions of this Agreement or any other Credit Document on the part of any Credit Party or to inspect the property (including the books and records) of any Credit Party; (iv) shall not be responsible to any Bank or Issuing Bank for the perfection, priority, existence, sufficiency or value of any security, guaranty or insurance or for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other Credit Document or any other instrument or document furnished pursuant hereto or thereto; and (v) shall incur no liability under or in respect of any Credit Document by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopier, telegram, cable, telex or otherwise) believed by it in its reasonable judgment to be genuine and signed or sent by the proper party or parties. Without limiting the generality of the foregoing, insofar as each Issuing Bank is concerned, for purposes of determining compliance with any Credit Document (including Section 3.2 of this Agreement) with respect to any issuance or increase of any, or any addition of a letter

of credit to this Agreement as a, Letter of Credit, each Bank shall be deemed to have consented to, approved and accepted and to be satisfied with each matter required under any Credit Document (including Section 3.2 of this Agreement), unless the officer of such Issuing Bank responsible for the transactions contemplated by the Credit Documents shall have received written notice from such Bank prior to such issuance, increase or addition specifying its objection thereto and such Bank shall not have accepted after such issuance, increase or addition any Letter of Credit Fee associated with such increase or, in the case of an issuance of any, or any addition of a letter of credit to this Agreement as a, Letter of Credit, associated with such Letter of Credit; provided that this sentence is solely for the benefit of the Issuing Banks (and not any Credit Party) and shall not amend, waive or otherwise modify Section 3.2, Section 6.1(b) or any other provision applicable to any Credit Party, whether in respect of such Letter of Credit or any other Letter of Credit or matter.

     SECTION 7.4. Rights. With respect to its Commitments, the Revolving Credit Advances made by it and the Notes, if any, issued to it, or any Letter of Credit Interest held by it, Citibank shall have the same rights and powers under any such Note and the other Credit Documents as any other Bank and may exercise the same as though it was not the Agent. With respect to its Letter of Credit Commitments, the Reimbursement Obligations owed to it or any Letter of Credit Interest held by it, each of the Issuing Banks shall have the same rights and powers under this Agreement as any other Bank and may exercise the same as though it was not an Issuing Bank. Citibank, each Issuing Bank and the respective affiliates of each may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with, any Borrower, any Person who may do business with or own, directly or indirectly, securities of any Borrower and any other Person, all as if Citibank were not the Agent and each Issuing Bank were not an Issuing Bank, in each case without any duty to account therefor to the Banks or the Issuing Banks. In the event that Citibank or any of its affiliates shall be or become an indenture trustee under the Trust Indenture Act of 1939 (as amended, the “Trust Indenture Act”) in respect of any securities issued or guaranteed by any Credit Party, the parties hereto acknowledge and agree that any payment or property received in satisfaction of or in respect of any Obligation of such Credit Party hereunder or under any other Credit Document by or on behalf of Citibank in its capacity as the Agent for the benefit of any Bank of Issuing Bank under any Credit Document (other than Citibank or an affiliate of Citibank) and which is applied in accordance with the Credit Documents shall be deemed to be exempt from the requirements of Section 311 of the Trust Indenture Act pursuant to Section 311(b)(3) of the Trust Indenture Act.

     SECTION 7.5. Indemnification. (a) The Banks agree to indemnify the Agent (to the extent not reimbursed by the Borrowers), ratably according to the respective Letter of Credit Interests then held by each of the Banks plus the respective principal amounts of the Revolving Credit Advances owed to each of them (or if no Letter of Credit Interests or Revolving Credit Advances are at the time outstanding, ratably according to their respective Revolving Credit Commitments for TWC (or, if such Commitments have terminated, their respective Revolving Credit Commitments for TWC immediately prior to such termination)), from and against any and all claims, damages, losses, liabilities, costs, fees and expenses (including reasonable fees and disbursements of external counsel) of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Agent in any way relating to or arising out of this Agreement or any other Credit Document or any action taken or omitted by the Agent under this Agreement or any other Credit Document, including any of the foregoing incurred in connection with any action taken under Section 5.1(f) (EXPRESSLY INCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, FEE OR EXPENSE ATTRIBUTABLE TO THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OF THE AGENT, BUT EXCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, FEE OR EXPENSE ATTRIBUTABLE TO THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE AGENT). IT IS THE INTENT OF THE PARTIES HERETO THAT THE AGENT SHALL, TO THE EXTENT PROVIDED IN THIS SECTION 7.5, BE INDEMNIFIED FOR ITS OWN ORDINARY, SOLE OR

CONTRIBUTORY NEGLIGENCE. Without limitation of the foregoing, each Bank agrees to reimburse the Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including external counsel fees) incurred by the Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement or any other Credit Document to the extent that the Agent is not reimbursed for such expenses by the Borrowers.

     (a) The Banks agree to indemnify each Issuing Bank (to the extent not reimbursed by the Borrowers), ratably according to the respective Letter of Credit Interests then held by each of the Banks plus the respective principal amounts of the Revolving Credit Advances owed to each of them (or if no Letter of Credit Interests or Revolving Credit Advances are at the time outstanding, ratably according to their respective Revolving Credit Commitments for TWC (or, if such Commitments have terminated, their respective Revolving Credit Commitments for TWC immediately prior to such termination)), from and against any and all claims, damages, losses, liabilities, costs, fees and expenses (including reasonable fees and disbursements of external counsel) of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against such Issuing Bank in any way relating to or arising out of this Agreement or any other Credit Document or any action taken or omitted by any Issuing Bank under this Agreement or any other Credit Document (EXPRESSLY INCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, FEE OR EXPENSE ATTRIBUTABLE TO THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OF ANY ISSUING BANK, BUT EXCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, FEE OR EXPENSE ATTRIBUTABLE TO THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH ISSUING BANK). IT IS THE INTENT OF THE PARTIES HERETO THAT AN ISSUING BANK SHALL, TO THE EXTENT PROVIDED IN THIS SECTION 7.5, BE INDEMNIFIED FOR ITS OWN ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE. Without limitation of the foregoing, each Bank agrees to reimburse each Issuing Bank promptly upon demand for its ratable share of any out-of-pocket expenses (including external counsel fees) incurred by such Issuing Bank in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement or any other Credit Document to the extent that such Issuing Bank is not reimbursed for such expenses by the Borrowers.

     SECTION 7.6. Successor Agent. The Agent may resign at any time as Agent under this Agreement by giving written notice thereof to the Banks and the Borrowers and may be removed at any time with or without cause by the Majority Banks. Upon any such resignation or removal, the Majority Banks shall have the right to appoint, with the consent of the Borrowers (which consent shall not be unreasonably withheld and shall not be required if an Event of Default under Section 6.1(a) or 6.1(e) exists), a successor Agent from among the Banks. If no successor Agent shall have been so appointed by the Majority Banks with such consent, and shall have accepted such appointment, within 30 days after the retiring Agent’s giving of notice of resignation or the Majority Banks’ removal of the retiring Agent, then the retiring Agent may, on behalf of the Banks, appoint a successor Agent, which shall be a Bank which is a commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as Agent under this Agreement by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent and shall function as the Agent under this Agreement, and the retiring Agent shall be discharged from its duties and obligations as Agent under this Agreement. After any retiring Agent’s resignation or removal hereunder as Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement.

     SECTION 7.7. Bank Decisions. Each of the Agent, the Banks and the Issuing Banks acknowledges that it has, independently and without reliance upon the Agent, the Syndication Agent, the Joint Lead Arrangers, the Issuing Banks or any other Bank and based on the financial statements referred to in Section 4.1(e) and such other documents and information as it has deemed appropriate, made its own credit analysis and its own decision to enter into this Agreement. Each of the Agent, the Banks and the Issuing Banks (in each case, both on its own behalf and on behalf of its affiliates, directors, officers, employees and agents that are Indemnified Parties) also acknowledges that it will, independently and without reliance upon the Agent, the Syndication Agent, the Joint Lead Arrangers, the Issuing Banks or any other Bank and based on such documents and information as it shall deem appropriate at the time, continue to make its own decisions in taking or not taking action under this Agreement and the other Credit Documents.

     SECTION 7.8. Certain Rights of the Agent. If the Agent shall request instructions from the Majority Banks with respect to any act or action (including failure to act) in connection with this Agreement or any other Credit Document, the Agent shall be entitled to refrain from such act or taking such action unless and until the Agent shall have received instructions from the Majority Banks; and it shall not incur liability to any Person by reason of so refraining. Without limiting the foregoing, no Bank nor any Issuing Bank nor any Indemnified Party shall have any right of action whatsoever against the Agent as a result of its acting or refraining from acting hereunder or under any other Credit Document in accordance with the instructions of the Majority Banks. Furthermore, except for action expressly required of the Agent hereunder, the Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall be specifically indemnified to its satisfaction by the Banks against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action.

     SECTION 7.9. Other Agents. The Syndication Agent, the Co-Documentation Agents and the Joint Lead Arrangers have no duties or obligations under any Credit Document. None of the Syndication Agent, the Co-Documentation Agents or the Joint Lead Arrangers shall have, by reason of this Agreement or the other Credit Documents, a fiduciary relationship in respect of any Bank or any Issuing Bank, and nothing in this Agreement or other Credit Documents, express or implied, is intended or shall be so construed to impose on any of the Syndication Agent, the Co-Documentation Agents or the Joint Lead Arrangers any obligation in respect of this Agreement or other Credit Documents.

THE AGENT PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS, OR THE ADEQUACY OF THE PLATFORM AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS OR OMISSIONS IN THE COMMUNICATIONS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT PARTIES IN CONNECTION WITH THE COMMUNICATIONS OR THE PLATFORM.

The Agent agrees that the receipt of the Communications by the Agent at its e-mail address set forth above shall constitute effective delivery of the Communications to the Agent for purposes of the Credit Documents. Each of the Banks and the Issuing Banks agrees that notice to it (as provided in the next sentence) specifying that the Communications have been posted to the Platform shall constitute effective delivery of the Communications to such Bank or Issuing Bank, as the case may be, for purposes of the Credit Documents. Each of the Banks and the Issuing Banks agrees (i) to notify the Agent in writing (including by electronic communication) from time to time of such Bank’s or such Issuing Bank’s, as the case may be, e-mail address to which the foregoing notice may be sent by electronic transmission and (ii) that the foregoing notice may be sent to such e-mail address.

No failure on the part of any Bank, any Issuing Bank or the Agent to exercise, and no delay in exercising, any right under this Agreement or any other Credit Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies provided in this Agreement are cumulative and not exclusive of any remedies provided by law.

IT IS THE INTENT OF THE PARTIES HERETO THAT EACH INDEMNIFIED

     (c) If any payment of principal of, or Conversion of, or purchase pursuant to Section 2.6(c) of, any portion of any Eurodollar Rate Advance owed by any Borrower to any Bank is made other than on the last day of the Interest Period for such Eurodollar Rate Advance, as a result of a payment, prepayment or Conversion pursuant to this Agreement or acceleration of the maturity of the Notes pursuant to Section 6.1 or such purchase or assignment, such Borrower shall, upon demand by such Bank (with a copy of such demand to the Agent), pay to the Agent for the account of such Bank any amounts required to compensate such Bank for any additional losses, costs or expenses that it may reasonably incur as a result of such payment, purchase, assignment or Conversion, including any loss (excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Bank to fund or maintain such Eurodollar Rate Advance.

     (d) Without prejudice to the survival of any other agreement of the Borrowers hereunder, the agreements and obligations of the Borrowers contained in Sections 2.2, 2.6 and 2.8 and this Section 8.4 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the Notes.

     SECTION 8.5. Binding Effect; Transfers.

     (a) This Agreement shall become effective when it shall have been executed by the Borrowers, the Agent and the Issuing Banks, and when each Bank listed on the signature pages hereof has delivered an executed counterpart hereof to the Agent, has sent to the Agent a facsimile copy of its signature hereon or of its signature on a signature page hereof or has notified the Agent that such Bank has executed this Agreement and thereafter shall be binding upon and inure to the benefit of the Borrowers, the Agent, the Issuing Banks and each Bank and their respective successors and assigns; provided that the Borrowers shall not have the right to assign any of their rights hereunder or any interest herein without the prior written consent of the Banks and the Issuing Banks. Each Bank may assign to one or more banks, financial institutions or other entities all or a portion of its rights and obligations under this Agreement (including all or a portion of its Revolving Credit Advances owing to such Bank, any Note or Notes held by such Bank, its Letter of Credit Interest and any or all of its Revolving Credit Commitments); provided, that (i) each such assignment shall be of a constant, and not a varying, percentage of all rights and obligations under this Agreement and the Notes, (ii) except in the case of an assignment of all of a Bank’s rights and obligations under this Agreement or an assignment to another Bank, the amount of the Revolving Credit Commitment for TWC of the assigning Bank being assigned pursuant to each such assignment (determined as of the date of the Transfer Agreement with respect to such assignment) shall be in an aggregate amount of $5,000,000 (or such lesser amount as may be consented to by the Agent and the Borrowers) and in an integral multiple of $1,000,000 (unless otherwise consented to by the Agent and the Borrowers), (iii) each such assignment shall be to an Eligible Assignee, (iv) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance and recording in the Register maintained by the Agent, a Transfer Agreement and a processing and recordation fee of $3,500 (which fee shall be paid by such Eligible Assignee) and (v) each such assignment of any Revolving Credit Commitment for any Borrower shall be made only if the same percentage of the Revolving Credit Commitments of such assigning Bank for each of the other Borrowers and the same percentage of the LC Participation Percentage of the assigning Bank are simultaneously assigned by the assigning Bank to the same Eligible Assignee pursuant to the same Transfer Agreement. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Transfer Agreement, (x) the assignee thereunder shall be a party hereto as a “Bank” and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Transfer Agreement, have the rights and obligations of a Bank hereunder (including obligations to the Issuing Banks and the

Agent pursuant to Section 7.5) and (y) the Bank assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Transfer Agreement, relinquish its rights and be released from its obligations under this Agreement, except for rights and obligations which continue after repayment of the Reimbursement Obligations and Revolving Credit Advances or termination of this Agreement pursuant to the express terms of this Agreement (and, in the case of a Transfer Agreement covering all of an assigning Bank’s rights and obligations under this Agreement, such Bank shall cease to be a party hereto, except as to such rights and obligations).

     (b) By executing and delivering a Transfer Agreement, the Bank assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Transfer Agreement, such assignor makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement, any other Credit Document or any other instrument or document furnished pursuant hereto or in connection herewith, the perfection, priority, existence, sufficiency or value of any security, guaranty or insurance or the execution, legality, validity, enforceability, genuineness, sufficiency or value of any Credit Document or any other instrument or document furnished pursuant hereto or in connection herewith, (ii) such assignor makes no representation or warranty and assumes no responsibility with respect to the financial condition of any Borrower or any other Person or the performance or observance by any Borrower or any other Person of any of its respective obligations under the Credit Documents or any other instrument or document furnished pursuant hereto or in connection herewith; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of such financial statements and such other documents and information as it has deemed appropriate to make its own credit analysis and its own decision to enter into such Transfer Agreement; (iv) such assignee will, independently and without reliance upon the Agent, any Issuing Bank, such assignor or any other Bank and based on such financial statements and such other documents and information as it shall deem appropriate at the time, continue to make its own credit analysis and its own decisions in taking or not taking action under this Agreement, any of the other Credit Documents or any other instrument or document; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to act as Agent on its behalf and to exercise such powers and discretion under this Agreement, any other Credit Document or any other document executed in connection herewith or therewith as are delegated to the Agent by the terms hereof or thereof, together with such powers and discretion as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Bank.

     (c) The Agent shall maintain a copy of each Transfer Agreement delivered to and accepted by it and a register for the recordation of the names and addresses of each Bank and each Issuing Bank together with its respective Revolving Credit Commitment for each Borrower, Letter of Credit Commitment, LC Participation Percentage, Letter of Credit Interest and the principal amount of the Revolving Credit Advances owing to each Bank by each Borrower from time to time (the “Register”). The entries in the Register made pursuant to this Section 8.5(c) shall be conclusive and binding for all purposes, absent manifest error, and the Borrowers, the Agent, the Issuing Banks and the Banks may treat as a Bank or Issuing Bank, as the case may be, each Person whose name is recorded in the Register as a Bank or Issuing Bank, as the case may be, hereunder for all purposes of this Agreement. The Register shall be available for inspection by any Borrower, any Issuing Bank or any Bank at any reasonable time and from time to time upon reasonable prior notice.

     (d) Upon its receipt of a Transfer Agreement executed and completed by an assigning Bank and an assignee representing that it is an Eligible Assignee (and consented to by the Agent, the Issuing Banks and, if required, by TWC), the Agent shall (i) accept such Transfer Agreement, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrowers. If

requested by the assigning or assignee Bank, each Borrower after its receipt of such notice, shall, at its own expense, execute and deliver to the Agent, any Notes requested pursuant to Section 2.10(a) (with any Notes being replaced thereby being promptly returned to such Borrower by the holder thereof). Such new Notes shall be dated the effective date of such Transfer Agreement and shall otherwise be in substantially the form of Exhibit G hereto.

     (e) Each Bank or Issuing Bank may sell participations to one or more banks or other entities (other than the Borrowers or any of their Affiliates) in or to all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment, the Revolving Credit Advances owing to it, the Notes held by it and its Letter of Credit Interest); provided, that (i) such Bank’s or Issuing Bank’s, as the case may be, obligations under this Agreement shall remain unchanged, (ii) such Bank or Issuing Bank, as the case may be, shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Bank shall remain the holder of any such Note for all purposes of this Agreement, (iv) the Borrowers, the Agent, each other Issuing Bank and the other Banks shall continue to deal solely and directly with such Bank or Issuing Bank, as the case may be, in connection with such Bank’s or Issuing Bank’s, as the case may be, rights and obligations under this Agreement, (v) all amounts payable under this Agreement shall be calculated as if such Bank or Issuing Bank, as the case may be, had not sold such participation, and (vi) the terms of any such participation shall not restrict such Bank’s or Issuing Bank’s, as the case may be, ability to consent to any departure by any Borrower herefrom without the approval of the participant, except that the approval of the participant may be required to the extent that such amendment, waiver or consent would reduce the principal of, or interest on, the Reimbursement Obligations or Revolving Credit Advances or any fees or other amounts payable hereunder, in each case to the extent subject to such participation, or postpone any date fixed for any payment of principal of, or interest on, the Reimbursement Obligations or Revolving Credit Advances or any fees or other amounts payable hereunder, in each case to the extent subject to such participation.

     (f) Notwithstanding any other provisions set forth in this Agreement, any Bank or Issuing Bank may at any time create a security interest in all or any portion of its rights under this Agreement (including its Letter of Credit Interest) or any of its Notes in favor of any Federal Reserve Bank in accordance with Regulation A of the Federal Reserve Board without notice to or consent of the Borrowers, the Issuing Banks or the Agent. Furthermore, any Bank or Issuing Bank may assign, as collateral or otherwise, any of its rights (including rights to payments of principal of and/or interest on its Letter of Credit Interest or Revolving Credit Advances made by such Bank) under this Agreement, its Notes or any of its Letter of Credit Interest to any Federal Reserve Bank without notice to or consent of any Borrower, the Issuing Banks or the Agent.

     (g) Notwithstanding anything to the contrary contained herein, any Bank or Issuing Bank (a “Designating Bank”) with the consent of the Agent (and, if no Event of Default has occurred and is continuing, the Borrowers) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Designating Bank to the Agent and the Borrowers, the option to fund all or any part of any payment to any Issuing Bank or Revolving Credit Advance which the Designating Bank has agreed to make; provided that no Designating Bank shall have granted at any one time such option to more than one SPC; and provided further that (i) such Designating Bank’s obligations under this Agreement shall remain unchanged, (ii) such Designating Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the Borrowers, the Issuing Banks, the Agent and the other Banks shall continue to deal solely and directly with such Designating Bank in connection with such Designating Bank’s rights and obligations under this Agreement, (iv) any such option granted to an SPC shall not constitute a commitment by such SPC to fund any drawing under a Letter of Credit or to fund any Revolving Credit Advance, and (v) neither the grant nor the exercise of such option to an SPC shall increase the costs or expenses or otherwise increase or change the obligations of a Borrower under this Agreement (including its obligations under Section 2.6). The issuance of a

Letter of Credit or the making of a Revolving Credit Advance by an SPC hereunder shall utilize the Commitment of the Designating Bank to the same extent, and as if, such Revolving Credit Advance were made by or such Letter of Credit were issued by such Designating Bank. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement to the extent that any such indemnity or similar payment obligations shall have been paid by its Designating Bank. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States. In addition, notwithstanding anything to the contrary contained in this Section 8.5, an SPC may not assign its interest in any Letter of Credit Interests or Revolving Credit Advance except that, with notice to, but without the prior written consent of, the Borrowers and the Agent and without paying any processing fee therefor, such SPC may assign all or a portion of its interests in any Letter of Credit Interests or Revolving Credit Advance to the Designating Bank or to any financial institutions (consented to by the Borrowers, Issuing Banks and Agent), providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Letter of Credit Interests or Revolving Credit Advance. Each Designating Bank shall serve as the agent of its SPC and shall on behalf of its SPC: (i) receive any and all payments made for the benefit of such SPC and (ii) give and receive all communications and notices, and vote, approve or consent hereunder, and take all actions hereunder, including votes, approvals, waivers, consents and amendments under or relating to this Agreement, the Notes and the other Credit Documents. Any such notice, communication, vote, approval, waiver, consent or amendment shall be signed by the Designating Bank for the SPC and need not be signed by such SPC on its own behalf. The Borrowers, the Issuing Banks, the Agent and the Banks may rely thereon without any requirement that the SPC sign or acknowledge the same or that notice be delivered to the Borrowers or the SPC. This Section 8.5(g) may not be amended without the written consent of any SPC, which shall have been identified to the Agent and the Borrowers.

     SECTION 8.6. Governing Law. This Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York.

     SECTION 8.7. Interest. It is the intention of the parties hereto that the Agent, each Issuing Bank and each Bank shall conform strictly to usury laws applicable to it, if any. Accordingly, if the transactions with the Agent, any Issuing Bank or any Bank contemplated hereby would be usurious under applicable law, then, in that event, notwithstanding anything to the contrary in this Agreement, any Credit Document or any other agreement entered into in connection with or as security for this Agreement or any other Credit Document, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under applicable law that is contracted for, taken, reserved, charged or received by the Agent, such Issuing Bank or such Bank, as the case may be, under this Agreement or any other Credit Document or under any other agreement entered into in connection with or as security for this Agreement, the Notes or the other Credit Documents shall under no circumstances exceed the maximum amount allowed by such applicable law and any excess shall be canceled automatically and, if theretofore paid, shall at the option of the Agent, such Issuing Bank or such Bank, as the case may be, be credited by the Agent, such Issuing Bank or such Bank, as the case may be, on the principal amount of the obligations owed to the Agent, such Issuing Bank or such Bank, as the case may be, by the applicable Borrower or refunded by the Agent, such Issuing Bank or such Bank, as the case may be, to the applicable Borrower, and (ii) in the event that the maturity of any obligation payable to the Agent, such Issuing Bank or such Bank, as the case may be, is accelerated or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to the Agent, such Issuing Bank or such Bank, as the case may be, may never include more than the maximum amount allowed by such applicable law and excess interest, if any, to the Agent, such Issuing Bank or such Bank, as the case may be, provided for

in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall, at the option of the Agent, such Issuing Bank or such Bank, as the case may be, be credited by the Agent, such Issuing Bank or such Bank, as the case may be, on the principal amount of the obligations owed to the Agent, such Issuing Bank or such Bank, as the case may be, by the applicable Borrower or refunded by the Agent, such Issuing Bank or such Bank, as the case may be, to the applicable Borrower.

All warranties, representations and covenants made by any Borrower or any Authorized Officer of any Borrower herein or in any certificate or other document delivered in connection with this Agreement shall be considered to have been relied upon by the Banks and the Issuing Banks and shall survive the issuance of any Letters of Credit and the issuance and delivery of the Notes (if any) and the making of Revolving Credit Advances regardless of any investigation.

     SECTION 8.10. Confidentiality. Each Bank agrees that it will not disclose without the prior consent of TWC (other than to employees, auditors, accountants, counsel or other professional advisors of the Agent, any Issuing Bank or any Bank) any information with respect to the Borrowers, which is furnished pursuant to this Agreement; provided that any Bank and any Issuing Bank may disclose any such information (1) as has become generally available to the public, (2) as may be required or appropriate in any report, statement or testimony submitted to or required by any regulatory body having or claiming to have jurisdiction over such Bank or Issuing Bank or submitted to or required by the Federal Reserve Board or the Federal Deposit Insurance Corporation or similar organizations (whether in the United States or elsewhere) or their successors, (3) as may be required or appropriate in response to any summons or subpoena in connection with any litigation, (4) in order to comply with any law, order, regulation or ruling applicable to such Bank or Issuing Bank, (5) to the prospective transferee or grantee in connection with any contemplated transfer of any of the Commitments, Letter of Credit Interests or Revolving Credit Advances or any interest therein by such Bank or Issuing Bank or the grant of an option to an SPC to fund any drawing under a Letter of Credit or Revolving Credit Advance; provided that such prospective transferee executes an agreement with or for the benefit of the Borrowers containing provisions substantially identical to those contained in this Section 8.10; and provided further that if the contemplated transfer is a grant of an option to fund a drawing under a Letter of Credit or Revolving Credit Advance to an SPC pursuant to Section 8.5(g), such SPC may disclose, if prior notice of the delivery thereof is given to the Borrowers, such information as may be required by law or regulation to be delivered, (6) in connection with the exercise of any remedy by such Bank or Issuing Bank following an Event of Default, (7) in connection with any litigation involving such Bank pertaining to this Agreement, any of the Notes or any of the other Credit Documents or any other document delivered in connection herewith, (8) to any Bank, any Issuing Bank or the Agent or (9) to any affiliate of any Bank; provided that such affiliate has agreed with or for the benefit of the Borrowers to be bound by provisions substantially identical to those contained in this Section 8.10.

     SECTION 8.11. Waiver of Jury Trial. THE BORROWERS, THE AGENT, THE ISSUING BANKS AND THE BANKS HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OF THE NOTES, ANY LETTER OF CREDIT, ANY OTHER CREDIT DOCUMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

     SECTION 8.12. Severability. In the event any one or more of the provisions contained in this Agreement or in any other Credit Document should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby. The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

     SECTION 8.13. Forum Selection and Consent to Jurisdiction; Damages. ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, ANY CREDIT DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE AGENT, THE BANKS, ANY ISSUING BANK OR THE BORROWERS IN CONNECTION HEREWITH OR THEREWITH MAY BE BROUGHT AND MAINTAINED IN THE COURTS OF THE STATE OF NEW YORK SITTING IN THE COUNTY OF NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY SECURITY MAY BE BROUGHT, AT THE AGENT’S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH SECURITY MAY BE FOUND.

Williams Completes $1.5 Billion Unsecured Revolving Credit Facility
Company Removes Secured Debt Obligation

     TULSA, Okla. — Williams (NYSE:WMB) announced today that it has obtained a new unsecured, three-year, $1.5 billion revolving credit facility.

     The new facility was significantly over subscribed, which allowed Williams to upsize the facility from the offered $1.275 billion to $1.5 billion.

     Williams plans to use the new facility primarily for general corporate purposes and issuing letters of credit. It replaces a $1.275 billion credit facility that was secured with equity in Transcontinental Gas Pipe Line Corp.

     The new revolver removes the last secured debt from Williams’ credit portfolio, except for non-recourse project debt in its Venezuelan operations.

     “We’re very pleased that our bank group recognized the progress we’ve made to strengthen our balance sheet, grow earnings, increase cash flow and reduce risk,” said Don Chappel, Williams’ chief financial officer.

     “The new revolver gives Williams even greater resources and flexibility to continue to grow our core natural gas businesses, while improving the company’s credit quality at the same time,” Chappel added.

     With the addition of the new revolver, Williams has a total of $2.7 billion in unsecured credit facilities. Williams will update its available liquidity on May 4 when it releases first-quarter financial results.

     Citigroup Global Markets Inc. and Banc of America Securities LLC were the joint lead arrangers and co-book runners on the new revolver.

About Williams (NYSE:WMB)

Williams, through its subsidiaries, primarily finds, produces, gathers, processes and transports natural gas. The company also manages a wholesale power business. Williams’ operations are concentrated in the Pacific Northwest, Rocky Mountains, Gulf Coast, Southern California and Eastern Seaboard. More information is at www.williams.com.
