The Commitments are not revolving; and amounts repaid may not be reborrowed.

(b) The failure of any Lender to make its Loan in connection with either the ▇▇▇▇-▇▇▇▇▇ Advance or the Western Gas Advance shall not relieve such Lender of its obligation hereunder to make its Loan in connection with the other of such advances, nor shall it relieve any other Lender of its obligation hereunder to make its Loan in connection with the ▇▇▇▇-▇▇▇▇▇ Advance and the Western Gas Advance, provided that the Commitments of the Lenders are several and no Lender shall be responsible for any other Lender’s failure to make any Loan as required.

Eurodollar Loans shall be made and maintained by each Lender at either its Eurodollar Lending Office or its Domestic Lending Office, at its option, provided that the exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement or create or increase any obligation of the Borrower not otherwise arising, or arising in such increased amount, under Section 2.14.

(f) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s obligation with respect to each resulting Loan.

(g) If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Loan prior to the end of the Interest Period applicable thereto, then, unless such Loan is repaid as provided herein, at the end of such Interest Period such Loan shall be continued as a Eurodollar Loan with an Interest Period having one month’s duration. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Majority Lenders, so notifies the Borrower, then, so long as such Event of Default is continuing (i) no outstanding Loan may be continued as a Eurodollar Loan, and (ii) unless repaid, each Eurodollar Loan shall be continued as an Alternate Base Rate Loan at the end of the Interest Period applicable thereto.

The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower designated by the Borrower in the Borrowing Request.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the Borrowing Date in connection with the ▇▇▇▇-▇▇▇▇▇ Advance or the Western Gas Advance, as the case may be, that such Lender will not make available to the Administrative Agent its Loan to be made in connection therewith, the Administrative Agent may assume that such Lender has made such Loan available on such date in accordance with Section 2.12(a) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its Loan in connection therewith, then each such Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the cost incurred by the Administrative Agent for making the proceeds of such Lender’s Loan available to the Borrower and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation, or (ii) in the case of the Borrower, the interest rate applicable to Alternate Base Rate Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan.

Section 2.13 Pro Rata Treatment and Payments.

(a) Each Loan and each payment (including each prepayment) by the Borrower on account of the principal of and interest on the Loans and any reduction of the Commitments of the Lenders shall be made pro rata according to each Lender’s Applicable Percentage, except that (i) payments or prepayments, and offsets against or reductions from the amount of payments and prepayments, in each case, specifically for the account of a particular

Lender under the terms of Section 2.14, Section 2.15, Section 2.16, Section 2.22, Section 9.03 or Section 9.13 shall be made for the account of such Lender, and (ii) if any Lender shall become a Defaulting Lender, from and after the date upon which such Lender shall have become a Defaulting Lender, any payment made on account of principal of or interest on the Loans or fees in respect of undrawn Commitments shall be applied, first for the account of the Lenders other than the Defaulting Lender, pro rata according to the Applicable Percentage of such non-defaulting Lenders, until the principal of and interest on the Loans and fees in respect of undrawn Commitments of such non-defaulting Lenders shall have been paid in full and, second for the account of such Defaulting Lender, provided that the failure to so pay such Defaulting Lenders shall not constitute an Event of Default or a Default, and no payment of principal of or interest on the Loans of such Defaulting Lender shall be considered to be overdue for purposes of Section 2.10(a), if, had such payments been applied without regard to this clause (ii), no such Event of Default or Default would have occurred and no such payment of principal of or interest on the Loans of such Defaulting Lender would have been overdue. All payments (including prepayments) to be made by the Borrower whether on account of principal, interest fees or otherwise shall be made in Dollars and in immediately available funds without setoff or counterclaim at or before 12:00 noon, New York City time on the day when due and shall be made to the Administrative Agent on behalf of the Lenders to the account of the Administrative Agent as notified to the Borrower from time to time at least five (5) Business Days before any change in such account. On the date of this Agreement, the account for payments of the Administrative Agent is 860050-524. The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received.

(b) If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant to the two preceding sentences, interest thereon shall be payable at the then applicable rate during such extension.

(c) Except as provided in Section 2.14, Section 2.15, Section 2.16, Section 2.22, Section 9.03, Section 9.13, and this Section 2.13, if any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of the Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of a Loan made by such Lender and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by such Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as

consideration for the assignment of or sale of a participation in any Loan made by such Lender to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the cost incurred by the Administrative Agent for making such distributed amount and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.12(b) or Section 2.13(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

Section 2.14 Increased Cost of Loans.

(a) If any change in any applicable law, treaty or governmental regulation after the date of this Agreement, or in the interpretation or application thereof after the date of this Agreement, or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made or issued after the date of this Agreement, which:

(i) does or shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, or deposits or other liabilities in or for the account of, advances or loans by, or other credit extended by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the Eurodollar Rate; or

(ii) does or shall impose on such Lender or the London interbank market any other condition affecting this Agreement, any Note or the Eurodollar Loans;

and the result of any of the foregoing is to increase the cost to such Lender of making, converting into, continuing or maintaining any Eurodollar Loan or to reduce any amount received or receivable by such Lender hereunder or under any Note (whether of principal, interest, or otherwise), then, in any such case, the Borrower shall pay such Lender, upon written demand

being made to the Borrower by such Lender, such additional amount or amounts which will compensate such Lender for such amounts as such Lender reasonably deems to be material with respect to this Agreement, the Notes or the Loans hereunder, provided, however, that if all or any such additional cost would not have been payable, or such reduction would not have occurred, but for such Lender’s decision to designate a new Eurodollar Lending Office or Domestic Lending Office or refusal to change to another Eurodollar Lending Office or Domestic Lending Office as provided below, the Borrower shall have no obligation under this Section 2.14 to compensate such Lender for such amount. Each Lender shall also give written notice to the Borrower and the Administrative Agent of any event occurring after the date of this Agreement which would entitle such Lender to compensation pursuant to this Section 2.14 as promptly as practicable after it obtains knowledge thereof and, upon the request of the Borrower, such Lender will designate a different Eurodollar Lending Office or a Domestic Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be disadvantageous to such Lender. Notwithstanding the foregoing, in the event that any Lender shall demand payment pursuant to this Section 2.14, the Borrower may, upon at least two (2) Business Days’ notice to the Administrative Agent and such Lender, convert in whole (but not in part) the Eurodollar Loans of such Lender into Alternate Base Rate Loans, in the case of Eurodollar Loans made to the Borrower, without regard to the requirements of Section 2.10.

(b) If any Lender shall have reasonably determined that the adoption after the date of this Agreement of any law, rule or regulation regarding capital adequacy, or any change therein or in the interpretation or application thereof after the date of this Agreement or compliance by any Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any central bank or Governmental Authority made or issued after the date of this Agreement, does or shall have the effect of reducing the rate of return on such Lender’s capital, or on the capital of such Lender’s holding company, if any, as a consequence of its obligations hereunder to a level below that which such Lender, or such Lender’s holding company, could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy) by an amount reasonably deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction from and after such date the Borrower receives the request; provided, however, that the foregoing shall not apply to any capital adequacy requirement imposed solely by reason of any business combination effected after the date hereof.

(c) A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company (describing in reasonable detail the basis for such demand), as the case may be, as specified in paragraph (a) or (b) of this Section 2.14 shall be delivered to the Borrower (with a copy to the Administrative Agent) together with any demand pursuant to such paragraphs and shall be prima facie evidence of the amount of such payment. The Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(d) Failure or delay on the part of any Lender to demand compensation pursuant to this Section 2.14 shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender pursuant to this Section 2.14 for any increased costs or reductions incurred more than 270 days prior to the date that such Lender notifies the Borrower of the change in law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor; provided further that, if the change in law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 2.15 Illegality. Notwithstanding anything herein contained, if any Lender shall make a good faith determination that a change in any applicable law or regulation after the date of this Agreement or in the interpretation thereof after the date of this Agreement by any authority charged with the administration thereof shall make it unlawful for such Lender to give effect to its obligations to make, convert, continue or maintain its Eurodollar Loans under this Agreement, the obligation of such Lender to make, convert, continue or maintain Eurodollar Loans hereunder shall be suspended for the duration of such illegality. Such Lender, by written notice to the Administrative Agent and to the Borrower, shall declare that such Lender’s obligation to make, convert, continue and/or maintain Eurodollar Loans shall be suspended, and the Borrower, on the last day of the then current Interest Period applicable to such Eurodollar Loans or portion thereof or, if such Lender so requests, on such earlier date as may be required by relevant law, shall convert such Eurodollar Loans or portion thereof into Alternate Base Rate Loans without regard to the requirements of Section 2.10. If and when such illegality ceases to exist, such suspension shall cease and such Lender shall notify the Borrower and the Administrative Agent and any Loans previously converted from Eurodollar Loans to Alternate Base Rate Loans pursuant to this Section 2.15 may be converted into Eurodollar Loans.

Section 2.16 Taxes.

(a) Any and all payments by or on account of any obligation of the Borrower under each Loan Document shall be made free and clear of and without deduction or withholding for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct or withhold any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions or withholding (including deductions or withholding applicable to additional sums payable under this Section 2.16), the Administrative Agent or any Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions or withholding been made, (ii) the Borrower shall make such deductions or withholding, and (iii) the Borrower shall pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law.

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) The Borrower shall indemnify the Administrative Agent and each Lender, within ten (10) days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Lender on or with respect to any

payment by or on account of any obligation of the Borrower under each Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 2.16) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower (including, without limitation, Form W-8BEN or Form W-8ECI, as applicable) as will permit such payments to be made without withholding or at a reduced rate.

(f) For any period during which a Foreign Lender has failed to provide the Borrower with the appropriate documentation as required by Section 2.16(e), the Borrower shall not be obligated to pay, and such Foreign Lender shall not be entitled to secure additional amounts under this Section 2.16 with respect to Indemnified Taxes imposed by a Governmental Authority to the extent that such additional amounts would not have arisen but for such failure of such Foreign Lender.

(g) If the Administrative Agent or a Lender determines, in its sole discretion, that it has received a refund of any Indemnified Taxes or Other Taxes (or any other taxes owed by the Administrative Agent or a Lender under this Agreement and indemnified by the Borrower or paid by the Borrower on behalf of a Lender) as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 2.16, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.16 with respect to the Indemnified Taxes or Other Taxes (or any other taxes owed by the Administrative Agent or a Lender under this Agreement and indemnified by the Borrower or paid by the Borrower on behalf of a Lender) giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, however, that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to forthwith repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such

Governmental Authority. Nothing contained in this Section 2.16 shall require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

Section 2.17 Substitute Loan Basis. In the event that prior to the commencement of any Interest Period for any Eurodollar Loan the Majority Lenders shall reasonably determine (which determination shall be final and conclusive and binding upon the Borrower) that (a) by reason of changes affecting the London Interbank Eurodollar Market, adequate and fair means do not exist for ascertaining the Eurodollar Rate for such requested Interest Period, or (b) the Eurodollar Rate will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans for such Interest Period then, and in any such event, the Administrative Agent shall forthwith give notice to the Borrower and (i) any Loans that were to have been made or continued on the first day of such Interest Period as Eurodollar Loans shall be made or converted into Alternate Base Rate Loans on the date upon which such Loans were to have been made or continued, and (ii) any outstanding Eurodollar Loans shall be converted, on the last day of the Interest Period applicable thereto, into Alternate Base Rate Loans. The Administrative Agent shall give written notice to the Borrower of any event occurring after the giving of such notice which permits an adequate and fair means of ascertaining the Eurodollar Rate and until such notice by the Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the Borrower have the right to continue as Eurodollar Loans.

Section 2.18 Certain Prepayments or Continuations. If the Eurodollar Loans of any Lender are converted into Alternate Base Rate Loans pursuant to Section 2.14 or Section 2.15 (such Eurodollar Loans being herein called “Affected Loans”), unless and until such Lender gives written notice that the circumstances which gave rise to such conversion no longer exist (which such Lender agrees to do promptly upon such circumstances ceasing to exist) all Loans which would otherwise be made or converted by such Lender into Affected Loans shall be made instead as, or converted into Alternate Base Rate Loans (on which interest and principal shall be payable simultaneously with the related Affected Loans of the other Lenders).

Section 2.19 Certain Notices. Notices by the Borrower under each of Section 2.03, Section 2.06, Section 2.07, Section 2.10, Section 2.14 and Section 2.17, and under the definition of “Interest Period” in Section 1.01 (a) shall be given in writing, by telecopy or by telephone (confirmed promptly in writing), and (b) shall be effective only if received by the Administrative Agent and, in the case of Section 2.14, the Lender involved, not later than 10:30 A.M. (New York City time) on the day specified in the respective Section or definition as the latest day such notice may be given. Notices by the Borrower under each of Section 2.03, Section 2.06, Section 2.07, Section 2.09, Section 2.10, Section 2.14 and Section 2.17 shall be irrevocable.

Section 2.20 Reserved.

Section 2.21 Minimum Amounts of Eurodollar Loans. All Loans and continuations of Loans hereunder and all selections of Interest Periods hereunder shall be in such amounts and be made pursuant to such elections so that, after giving effect thereto, the aggregate principal amount of the Loans comprising each Eurodollar Loan shall be equal to $10,000,000 or a whole multiple of $5,000,000 in excess thereof.

Section 2.22 Break Funding Payments. In the event of the payment of any principal amount of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), the continuation of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, the failure to borrow, continue or prepay any Loan on the date specified in any notice delivered pursuant hereto, or the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Eurodollar Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the Eurodollar market. A certificate of any such Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 2.22 shall be delivered to the Borrower and the Administrative Agent and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof. Notwithstanding anything to the contrary contained herein no Lender shall be entitled to receive any amount or amounts pursuant to this Section if such amount or amounts are attributable solely to the merger or other consolidation of such Lender with another Lender.

ARTICLE III
REPRESENTATIONS AND WARRANTIES

Section 3.01 Representations of the Borrower. The Borrower represents and warrants to the Administrative Agent and the Lenders that:

(a) The Borrower (i) has been duly incorporated and is validly existing and in good standing under the laws of the State of Delaware, and (ii) is qualified to do business as a foreign corporation and is in good standing in each jurisdiction of the United States in which the ownership of its properties or the conduct of its business requires such qualification and where the failure to so qualify would constitute a Material Adverse Change.

(b) This Agreement and all other Loan Documents to which the Borrower is a party have been duly authorized, executed and delivered by the Borrower, and each of this Agreement, the Notes and the other Loan Documents to which it is a party constitutes a valid and binding agreement of the Borrower, enforceable in accordance with its respective terms, subject to the effect of applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally and equitable principles of general applicability. The Notes have been duly authorized by the Borrower and, when executed, issued and delivered pursuant hereto for value received, will constitute valid and binding obligations of the Borrower, enforceable in accordance with their terms, except as (i) may be limited by bankruptcy, insolvency or similar laws affecting creditors’ rights generally, and (ii) rights of acceleration and the availability of equitable

remedies may be limited by equitable principles of general applicability. There are no actions, suits or proceedings pending or, to the knowledge of the Borrower, threatened against the Borrower which purports to affect the legality, validity or enforceability of this Agreement, any other Loan Document or any of the Notes.

(c) The execution, delivery and performance of this Agreement by the Borrower and the execution, issuance, delivery and performance by the Borrower of the Notes will not violate or conflict with (A) the restated certificate of incorporation or bylaws of the Borrower, or (B) any indenture (including the Public Indenture), loan agreement or other similar agreement or instrument binding on the Borrower.

(d) To the knowledge of the Borrower, on the Effective Date there are no actions, suits, or proceedings pending or, to the knowledge of the Borrower, threatened against the Borrower before any Governmental Authority as to which, in the opinion of the Borrower, there is a reasonable possibility of an adverse determination and that, if adversely determined, could reasonably be expected, individually or in the aggregate, to constitute a Material Adverse Change.

(e) The consolidated balance sheets of the Borrower and its consolidated Subsidiaries as of December 31, 2004 and 2005, and the related consolidated statements of income, stockholders’ equity and cash flows for each of the years in the three-year period ended December 31, 2005, audited by KPMG LLP, present fairly, in all material respects, the consolidated financial position of the Borrower and its consolidated Subsidiaries as of December 31, 2004 and 2005, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2005, in conformity with GAAP applied on a consistent basis.

(f) Neither the Borrower nor any Subsidiary is an “investment company” as defined in, or subject to regulation under, the Investment Company Act of 1940.

(g) No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Change. The present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of all such underfunded Plans by an amount that could reasonably be expected to be a Material Adverse Change.

(h) Neither the Information Memorandum nor any of the other reports, financial statements, certificates or other information furnished by or on behalf of the Borrower to the Agents or any Lender in connection with the negotiation of this Agreement or delivered hereunder (as modified or supplemented by other information so furnished), taken as a whole, contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that other than the term sheet contained in the Information Memorandum, the information contained in the Information Memorandum is publicly available information and

has been provided therein for the convenience of the Lenders; and if there is a conflict between the information in the Information Memorandum and publicly available information, then the publicly available information will prevail; provided further that, the Borrower makes no representation or warranty concerning the statements, estimates and projections contained in the Information Memorandum with respect to the anticipated future performance of the Borrower, except that such statements, estimates and projections were made in good faith by the Borrower’s management, on the basis of assumptions believed by the Borrower’s management to be reasonable at the time and such statements, estimates and projections and the assumptions on which they are based may or may not prove to be correct.

(i) The Borrower’s “significant subsidiaries” (as defined in Regulation S-X of the Commission under the Securities and Exchange Act of 1934) as of the date immediately prior to the Effective Date are listed on Part A of Schedule II hereto.

(j) The Borrower has filed all United States Federal income tax returns and all other material tax returns and reports required to be filed (or obtained extensions with respect thereto) and has paid all taxes required to have been paid by it, except (i) taxes the validity of which are being contested in good faith by appropriate proceedings, and with respect to which the Borrower, to the extent required by GAAP, has set aside on its books adequate reserves or (ii) to the extent the failure to do so (individually or in the aggregate) would not reasonably be expected to result in a Material Adverse Change.

(k) No Event of Default has occurred and is continuing.

(l) The making of the Loans does not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority or any other third Person (including shareholders or any class of directors, whether interested or disinterested, of the Borrower or any other Person), nor is any such consent, approval, registration, filing or other action necessary for the validity or enforceability of any Loan Document, except such as have been obtained or made and are in full force and effect.

(c) Neither the execution and delivery of the Western Gas Acquisition Agreement by the Borrower and the Western Gas Merger Sub nor the consummation by each of the transactions contemplated thereby nor compliance by each with any of the provisions therein will (i) result in a violation or breach of or conflict with its respective certificate or articles of incorporation or bylaws, (ii) result in a violation or breach of or conflict with any provisions of, or constitute a default (or an event which, with notice or lapse of time or both, would constitute a default) under, or result in the termination, cancellation of, or give rise to a right of purchase under, or accelerate the performance required by, or result in a right of termination or acceleration under, or result in the creation of any Lien upon any of the properties or assets owned or operated by the Borrower or any Subsidiaries under, or result in being declared void, voidable, or without further binding effect, under any of the terms, conditions or provisions of any note, bond, mortgage, indenture, deed of trust, license, contract, lease, agreement or other instrument or obligation of any kind to which the Borrower or any of the Subsidiaries is a party or by which the Borrower or any of the Subsidiaries or any of their respective properties or assets is bound or (iii) subject to obtaining or making the consents, approvals, orders, authorizations, registrations, declarations and filings referred to in paragraph (d) below, violate any judgment, ruling order, writ, injunction, decree, statute, law (including common law), rule or regulation applicable to the Borrower or any of the Subsidiaries or any of their respective properties or assets, other than any such event described in items (ii) or (iii) which, individually or in the aggregate, has not had and would not reasonably be expected to have a Western Gas MAE.

(d) No consent, approval, order or authorization of, or registration, declaration or filing with, any Governmental Authority is necessary to be obtained or made by the Borrower or any of its Subsidiaries in connection with the Borrower’s or Western Gas Merger Sub’s execution, delivery and performance of the Western Gas Acquisition Agreement or the consummation by the Borrower and the Western Gas Merger Sub of the transactions contemplated thereby, except for (i) consents, approvals and governmental filings that have been made or obtained prior to such date, (ii) compliance with the DGCL, with respect to the filing of the Western Gas Certificate of Merger and (iii) such governmental or tribal consents, qualifications or filings as are customarily obtained or made following the transfer of interests in oil and gas properties, except in each case of clauses (ii) and (iii) where the failure to obtain or take such actions, individually or in the aggregate, has not had and would not reasonably be expected to have a Western Gas MAE.

(e) There is no preliminary injunction or other order, decree or ruling issued by a court of competent jurisdiction or by a Governmental Authority, nor any statute, rule,

regulation or executive order promulgated or enacted by any Governmental Authority, in effect that would make the Western Gas Merger illegal or otherwise prevent the consummation thereof.

(f) Immediately following the Western Gas Merger, the Borrower’s “significant subsidiaries” (as defined in Regulation S-X of the Commission under the Securities and Exchange Act of 1934) acquired in connection with the Western Gas Merger are listed on Part B of Schedule II hereto.

(g) To the Borrower’s knowledge, (i) Western Gas has the corporate power and authority to enter into the Western Gas Acquisition Agreement and to consummate the transactions contemplated thereby, (ii) neither Western Gas nor any of its Subsidiaries is an “investment company” as defined in, or subject to regulation under, the Investment Company Act of 1940 and (iii) Western Gas and each of its Subsidiaries is duly qualified and/or licensed, as may be required, to do business as a foreign corporation and is in good standing in each jurisdiction in which the nature of the business conducted by it or the character of the property owned, leased or used by it makes such qualification necessary, except in such jurisdictions where the failure to be so qualified and/or licensed, individually or in the aggregate, have not had or would not reasonably be expected to have a Western Gas MAE.

Neither any Agent nor any of their respective directors, officers, agents, employees or affiliates shall be (i) liable for any action taken or omitted to be taken by any of them hereunder or under any agreement executed and delivered pursuant to the terms hereof or in connection herewith or therewith except for their own gross negligence or willful misconduct, or (ii) responsible to the Lenders for any recitals, statements, warranties or representations herein or under any agreement, certificate or other document referred to or provide for in, or received by the Agents under or in connection with, this Agreement or any other Loan Document or for the value, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of the Borrower or any Subsidiary a party thereto to perform its obligations hereunder or thereunder. The Agents shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of the Borrower or any Subsidiary.

Section 8.03 Right to Indemnity. The Administrative Agent shall be fully justified in failing or refusing to take any action hereunder or under any agreement executed and delivered pursuant to the terms hereof unless it shall first be indemnified (upon requesting such indemnification) to its satisfaction by the Lenders against any and all liability and expense which it may incur by reason of taking or continuing to take any such action. The Lenders agree to indemnify the Administrative Agent in its capacity as such, to the extent not reimbursed by the Borrower under this Agreement, pro rata according to each Lender’s Applicable Percentage for any and all liabilities, obligations, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Administrative Agent as agent in any way relating to or arising out of this Agreement, the Notes, the Transactions or any other documents contemplated by or referred to herein (including the costs and expenses which the Borrower is obligated to pay under this

Agreement but excluding, unless an Event of Default has occurred and is continuing, normal administrative costs and expenses incident to the performance of its agency duties hereunder) or the enforcement of any of the terms hereof or thereof or of any such other documents; provided no such liability, obligation, damage, penalty, action, judgment, suit, cost, expense or disbursement results from the Administrative Agent’s gross negligence or willful misconduct; provided, further, that, in the event the Administrative Agent receives indemnification from the Lenders hereunder with respect to costs and expenses which the Borrower is obligated to pay under this Agreement, the Administrative Agent shall remit to the Lenders the amount of such costs and expenses to the extent subsequently paid by the Borrower, such remittance to be in accordance with the proportionate amount of the indemnification made by each respective Lender.

Section 8.04 Delegation of Duties. The Administrative Agent may employ agents and attorneys-in-fact and shall not be answerable, except as to money or securities received by them or their authorized agents, for the default or misconduct of any such agent or attorney-in-fact selected by it with reasonable care.

Section 8.05 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to the Borrower), independent accountants and other experts selected by the Administrative Agent or, in the case of counsel to or auditors of the accounts of the Borrower, the Borrower. The Administrative Agent may deem and treat the payee of any Note as the owner thereof for all purposes hereof unless and until a notice of the assignment or transfer thereof satisfactory to the Administrative Agent signed by such payee shall have been filed with the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Majority Lenders (or, if so specified by this Agreement, all Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Majority Lenders (or, if so specified by this Agreement, all Lenders), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans.

Section 8.06 Rights as a Lender. With respect to its Commitment and the Loans made by it, each Agent shall have the same rights and powers hereunder and under any agreement executed and delivered pursuant to the terms hereof as any Lender and may exercise the same as though it were not an Agent and the term “Lender” or “Lenders” shall, unless the context otherwise indicates, include each Agent in its capacity as a Lender hereunder and thereunder. Each Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of banking or trust business with the Borrower, the Subsidiaries and their respective Affiliates as if it were not an Agent.

Section 8.07 Non-Reliance on Agents or other Lenders. Each Lender agrees that it has, independently and without reliance on the Administrative Agent or on any other Lender, and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Borrower and decision to make each Loan to be made by such Lender hereunder and enter into this Agreement and that it will, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under this Agreement and the other Loan Documents. The Administrative Agent shall not be required to keep itself informed as to the performance or observance by the Borrower of this Agreement or any other document referred to or provided for herein or therein or to inspect the properties or books of the Borrower. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent shall have no duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of the Borrower or its Subsidiaries or which may at any time come into possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates.

Section 8.08 Events of Default. If the Administrative Agent receives actual knowledge of an Event of Default hereunder, it shall promptly inform the Lenders thereof. The Administrative Agent shall not be deemed to have actual knowledge of an Event of Default hereunder until it shall have received a written notice from the Borrower or any Lender referring to this Agreement, describing such Event of Default and stating that such notice is a “Notice of Default.”

Section 8.09 Successor Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders and the Borrower. Upon any such resignation, the Majority Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after such retiring Administrative Agent gives notice of its resignation, then such retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of such retiring Administrative Agent and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article VIII and Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as the Administrative Agent hereunder.

Section 8.10 Co-Advisors; Joint-Lead Arrangers and Co-Syndication Agents. Nothing contained in this Agreement shall be construed to impose any obligation or duty whatsoever on any Persons named on the cover of this Agreement or elsewhere in this Agreement as Co-Advisors, Joint-Lead Arrangers or Co-Syndication Agents, other than those applicable to all Lenders as such.

Section 9.02 Waivers; Amendments.

(a) No failure or delay by the Administrative Agent or any Lender in exercising any right or power hereunder or under the other Loan Documents shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent and the Lenders provided herein are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, to the fullest extent permitted by applicable law, the making of a Loan shall not be construed as a waiver of any Event of Default, regardless of whether the Administrative Agent or any Lender may have had notice or knowledge of such Event of Default at the time.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Majority Lenders or by the Borrower and the Administrative Agent with the consent of the Majority Lenders; provided that no such agreement shall (i) increase the

Commitment of any Lender without the written consent of such Lender, (ii) reduce or forgive any principal amount owing hereunder or reduce the rate of interest thereon or fee payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment or mandatory prepayment of any principal amount owing hereunder, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.13(a) or Section 2.13(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change Section 6.01, without the consent of each Lender, or (vi) change any of the provisions of this Section or the definition of “Majority Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent without the prior written consent of the Administrative Agent.

Section 9.03 Expenses; Indemnity; Damage Waiver.

(a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication (prior to the date hereof) of the credit facilities provided for herein, the preparation, execution, delivery and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions (including the Transactions) contemplated hereby or thereby shall be consummated) and (ii) all reasonable out-of-pocket expenses incurred by the Administrative Agent or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent or any Lender, in connection with the enforcement or protection of its rights under this Agreement and the other Loan Documents, including its rights under this Section, or in connection with the Loans made, including all such reasonable out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans. Notwithstanding anything to the contrary, the Borrower shall not have any obligation to pay the fees or expenses of any Lender or the Administrative Agent in connection with any assignment of, or the grant of any participation in, any rights of a Lender under or in connection with this Agreement; provided that the provisions of this sentence shall not apply to any Lender substituted for a Defaulting Lender pursuant to Section 9.13(b) and (c).

(b) The Borrower shall indemnify the Administrative Agent, each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery (but not the negotiation or preparation) of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or the use of the proceeds therefrom, (iii) any actual or alleged presence or release of hazardous materials on or from any property owned or operated by the Borrower or any Subsidiary, or any environmental

liability related in any way to the Borrower or any Subsidiary, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses either (i) did not result directly or indirectly from the action or inaction of the Borrower or any Subsidiary, or (ii) resulted from the gross negligence, unlawful conduct or willful misconduct of such Indemnitee.

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent under paragraph (a) or (b) of this Section 9.03, each Lender severally agrees to pay to the Administrative Agent such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such.

(d) All amounts due under this Section shall be payable promptly after written demand therefor together with a copy of the invoice(s) or other documentation setting forth in reasonable detail the amount demanded and the matter(s) to which it relates.

Section 9.04 Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder except as provided in Section 5.03 or with the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Each Lender may assign to one or more lenders or other entities (upon consultation with the Borrower) all or a portion of its rights and obligations under this Agreement and its Note subject to the conditions set forth in (b) below. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Related Parties of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement with the prior written consent (such consent not to be unreasonably withheld or delayed) of the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment of any Commitment to an assignee that is a Lender with a Commitment immediately prior to giving effect to such assignment or an Affiliate of a Lender.

(ii) Assignments shall be subject to the following additional conditions:

(A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s

Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $10,000,000 unless each of the Borrower and the Administrative Agent otherwise consent (such consent not to be unreasonably withheld or delayed), provided that no such consent of the Borrower shall be required if an Event of Default under Section 7.01(a), (b), (g), (h) or (i) has occurred and is continuing;

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement and, unless each of the Borrower and the Administrative Agent otherwise consent, shall result in the assigning Lender having no less than $10,000,000 in Commitments and Loans after giving effect to such assignment;

(C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(v) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 2.14, Section 2.16, Section 2.22 and Section 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in New York City or Stamford, Connecticut, a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be prima facie evidence of the existence and amounts of the obligations recorded therein, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b)(ii)(C) of this Section and any written consent to such assignment required by paragraph (b)(i) of this Section and upon satisfaction of the additional conditions set forth in paragraph (b)(ii) of this Section, the Administrative Agent shall accept such Assignment and Assumption and in the case of the Commitment, record the information contained therein in the Register maintained at the New York office of the Administrative Agent. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the applicable Register as provided in this paragraph.

(c) (i) Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Section 2.14, Section 2.16 and Section 2.22 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. Notwithstanding anything to the contrary, unless otherwise contractually agreed, no Participant shall be entitled to the benefits of Section 9.08 as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.14 or Section 2.16 than the Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.16 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.16(e) and Section 2.16(g) as though it were a Lender.

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System, and to a trustee for the benefit of holders of debt securities issued by such Lender, and this Section 9.04 shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or

assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Section 9.05 Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Event of Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any other amount payable under this Agreement is outstanding and unpaid. The provisions of Section 2.14, Section 2.16, Section 2.22, Section 9.03, this Section 9.05, and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans or the termination of this Agreement or any other provision hereof.

Section 9.06 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 6.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 9.07 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Section 9.08 Right of Setoff. If (a) an Event of Default shall have occurred and be continuing, and (b) the principal of the Loans has been accelerated each Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including

other rights of setoff) which such Lender may have. Upon the exercise by a Lender of its rights under this Section, such Lender shall notify the Administrative Agent and the Borrower thereof.

Section 9.09 Governing Law; Jurisdiction; Consent to Service of Process.

(a) This Agreement and the Notes shall be construed in accordance with and governed by the law of the State of New York.

(b) Each party hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the courts of the Supreme Court of the State of New York, sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from either thereof, in any action or proceeding arising out of or relating to this Agreement, the Notes, or the other Loan Documents, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State court or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall affect any right that the Administrative Agent, any of the other Agents or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against the Borrower or its properties in the courts of any jurisdiction. Each party to this Agreement hereby irrevocably waives any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens, which it may now or hereafter have to the bringing of any such action or proceeding in such respective jurisdictions.

(c) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

Section 9.10 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (a) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (b) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 9.11 Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

Section 9.12 Confidentiality. The Administrative Agent and each of the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors who have a reason to use such Information in connection with the administration of this Agreement (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential and will agree to use the Information solely for the purpose of such administration), (b) to the extent requested by any regulatory authority or any self-regulatory body having authority to regulate or oversee any aspect of any Lender’s (or any Affiliate of such Lender) business or property, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, or to any counterparty (or its advisor) to any swap, securitization, or derivative transaction referencing or involving any of its rights or obligations under this Agreement, (g) with the consent of the Borrower, or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent or any Lender on a non-confidential basis from a source other than the Borrower or any of its Affiliates. For the purposes of this Section, “Information” means all information received from the Borrower relating to the Borrower or its business, other than any such information that is available to the Administrative Agent or any Lender on a non-confidential basis prior to disclosure by the Borrower; provided that, in the case of information received from the Borrower after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Section 9.13 Termination and Substitution of Lender.

(a) If (i) the obligation of any Lender to make Eurodollar Loans or continue Loans as Eurodollar Loans has been suspended pursuant to Section 2.15, or (ii) any Lender has demanded compensation under Section 2.14 or Section 2.16, the Borrower may, upon three Business Days’ notice to such Lender through the Administrative Agent, prepay in full all of the outstanding Loans of such Lender, or its assignee, together with accrued interest thereon to the date of prepayment and all other amounts payable hereunder to such Lender accrued to the date of prepayment, and concurrently therewith terminate this Agreement with respect to such Lender by giving notice of such termination to the Administrative Agent and such Lender.
