As used herein, the following terms shall have the meanings specified below:

“ABR” shall mean for any day a fluctuating rate per annum equal to the highest of (a) the Federal Funds Effective Rate plus 1/2 of 1%, (b) the rate of interest in effect for such day as publicly announced from time to time by the Administrative Agent as its “prime rate” and (c) the LIBOR Rate for a one-month Interest Period on such day (or if such day is not a Business Day, the immediately preceding Business Day) plus 1.0%; provided that, for the avoidance of doubt, for purposes of calculating the LIBOR Rate pursuant to clause (c) above, the LIBOR Rate for any day shall be based on the rate per annum determined by the Administrative Agent at approximately 11:00 a.m. (London time) on such day by reference to the rate appearing on the Reuters Screen LIBOR01 Page (or any successor page or any successor service, or any substitute page or substitute for such service, providing rate quotations comparable to the Reuters Screen LIBOR01 Page, as determined by the Administrative Agent from time to time for purposes of providing quotations of interest rates applicable to dollar deposits in the London interbank market) for a period equal to one-month. The “prime rate” is a rate set by the Administrative Agent based upon various factors, including the Administrative Agent’s costs and desired return, general economic conditions and other factors, and is used as a reference point for pricing some loans, which may be priced at, above, or below such announced rate. Any change in the ABR due to a change in such rate announced by the Administrative Agent, in the Federal Funds Effective

Rate or in the one-month LIBOR Rate shall take effect at the opening of business on the day specified in the public announcement of such change.

“Acquired Business Representations” shall mean the representations and warranties made by the Seller with respect to the Acquired EP Business in the Purchase and Sale Agreement as are material to the interests of the Lenders, but only to the extent that EPE Acquisition, LLC (or one of its Affiliates) has the right to terminate the obligations of EPE Acquisition, LLC and its Affiliates under the Purchase and Sale Agreement as a result of a breach of such representations and warranties in the Purchase and Sale Agreement.

SECTION 2. Amount and Terms of Credit

2.1                               Commitments.

(a)                                 (i)                                     Subject to and upon the terms and conditions herein set forth, each Lender severally, but not jointly, agrees to make a loan or loans denominated in Dollars (each an “Initial Loan” and, collectively, the “Initial Loans”) to the Borrower, which Loans (i) shall be made at any time and from time to time on and after the Closing Date and prior to the Termination Date, (ii) may, at the option of the Borrower, be incurred and maintained as, and/or converted into, ABR Loans or LIBOR Loans; provided that all Loans made by each of the Lenders pursuant to the same Borrowing shall, unless otherwise specifically provided herein, consist entirely of Loans of the same Type, (iii) may be repaid and reborrowed in accordance with the provisions hereof, (iv) shall not, for any Lender at any time, after giving effect thereto and to the application of the proceeds thereof, result in such Lender’s Total Exposure at such time exceeding such Lender’s Commitment Percentage at such time of the Loan Limit and (v) shall not, after giving effect thereto and to the application of the proceeds thereof, result in the aggregate amount of all Lenders’ Total Exposures at such time exceeding the Loan Limit

(ii)                                  Each Lender may at its option make any LIBOR Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan, provided that (i) any exercise of such option shall not affect the obligation of the Borrower to repay such Loan and (ii) in exercising such option, such Lender shall use its reasonable efforts to minimize any increased costs to the Borrower resulting therefrom (which obligation of the Lender shall not require it to take, or refrain from taking, actions that it determines would result in increased costs for which it will not be compensated hereunder or that it determines would be otherwise disadvantageous to it and in the event of such request for costs for which compensation is provided under this Agreement, the provisions of Section 2.10 shall apply).

(b)                                      Subject to and upon the terms and conditions herein set forth, the Swingline Lender in its individual capacity agrees, at any time and from time to time on and after the Closing Date and prior to the Swingline Maturity Date, to make a loan or loans (each a “Swingline Loan” and, collectively, the “Swingline Loans”) to the Borrower in Dollars, which Swingline Loans (i) shall be ABR Loans, (ii) shall have the benefit of the provisions of Section 2.1(c), (iii) shall not exceed at any time outstanding the Swingline Commitment, (iv) shall not, after giving

60

effect thereto and to the application of the proceeds thereof, result at any time in the aggregate amount of the Lenders’ Total Exposure at such time exceeding the Total Commitment then in effect and (v) may be repaid and reborrowed in accordance with the provisions hereof. Each outstanding Swingline Loan shall be repaid in full on the earlier of (a) 15 Business Days after such Swingline Loan is initially borrowed and (b) the Swingline Maturity Date. The Swingline Lender shall not make any Swingline Loan after receiving a written notice from the Borrower, the Administrative Agent or any Lender stating that an Event of Default exists and is continuing until such time as the Swingline Lender shall have received written notice of (i) rescission of all such notices from the party or parties originally delivering such notice or (ii) the waiver of such Event of Default in accordance with the provisions of Section 13.1.

(c)                                  On any Business Day, the Swingline Lender may, in its sole discretion, give notice to each Lender that all then-outstanding Swingline Loans shall be funded with a Borrowing of Loans, in which case Loans constituting ABR Loans (each such Borrowing, a “Mandatory Borrowing”) shall be made on the immediately succeeding Business Day by each Lender pro rata based on each Lender’s Commitment Percentage, and the proceeds thereof shall be applied directly to the Swingline Lender to repay the Swingline Lender for such outstanding Swingline Loans. Each Lender hereby irrevocably agrees to make such Loans upon one Business Days’ notice pursuant to each Mandatory Borrowing in the amount and in the manner specified in the preceding sentence and on the date specified to it in writing by the Swingline Lender notwithstanding (i) that the amount of the Mandatory Borrowing may not comply with the minimum amount for each Borrowing specified in Section 2.2, (ii) whether any conditions specified in Section 7 are then satisfied, (iii) whether a Default or an Event of Default has occurred and is continuing, (iv) the date of such Mandatory Borrowing or (v) any reduction in the Total Commitment after any such Swingline Loans were made. In the event that, in the sole judgment of the Swingline Lender, any Mandatory Borrowing cannot for any reason be made on the date otherwise required above (including as a result of the commencement of a proceeding under the Bankruptcy Code in respect of the Borrower), each Lender hereby agrees that it shall forthwith purchase from the Swingline Lender (without recourse or warranty) such participation of the outstanding Swingline Loans as shall be necessary to cause the Lenders to share in such Swingline Loans ratably based upon their respective Commitment Percentages; provided that all principal and interest payable on such Swingline Loans shall be for the account of the Swingline Lender until the date the respective participation is purchased and, to the extent attributable to the purchased participation, shall be payable to such Lender purchasing same from and after such date of purchase.

2.2                               Minimum Amount of Each Borrowing; Maximum Number of Borrowings. The aggregate principal amount of each Borrowing shall be in a minimum amount of at least the Minimum Borrowing Amount for such Type of Loans and in a multiple of $100,000 in excess thereof and Swingline Loans shall be in a minimum amount of $100,000 and in a multiple of $10,000 in excess thereof (except that Mandatory Borrowings shall be made in the amounts required by Section 2.1(c) and Loans to reimburse the applicable Issuing Bank with respect to any Unpaid Drawing shall be made in the amounts required by Section 3.3 or Section 3.4, as applicable). More than one Borrowing may be incurred on any date; provided, that at no time shall there be outstanding more than ten Borrowings of LIBOR Loans under this Agreement.

61

2.3                               Notice of Borrowing.

(a)                                 Whenever the Borrower desires to incur Loans (other than Swingline Loans, Mandatory Borrowings or borrowings to repay Unpaid Drawings), the Borrower shall give the Administrative Agent at the Administrative Agent’s Office, (i) prior to 1:00 p.m. (New York City time) at least three Business Days’ prior written notice (or telephonic notice promptly confirmed in writing) of each Borrowing of Loans if such Loans are to be initially LIBOR Loans (or prior to 12:00 p.m. noon (New York City time) two Business Days’ prior written notice in the case of a Borrowing of Loans to be made on the Closing Date initially as LIBOR Loans) and (ii) written notice (or telephonic notice promptly confirmed in writing) prior to 11:00 a.m. (New York City time) on the date of each Borrowing of Loans that are to be ABR Loans. Such notice (together with each notice of a Borrowing of Swingline Loans pursuant to Section 2.3(b), a “Notice of Borrowing”) shall specify (A) the aggregate principal amount of the Loans to be made pursuant to such Borrowing, (B) the date of the Borrowing (which shall be a Business Day) and (C) whether the respective Borrowing shall consist of ABR Loans and/or LIBOR Loans and, if LIBOR Loans, the Interest Period to be initially applicable thereto (if no Interest Period is selected, the Borrower shall be deemed to have selected an Interest Period of one month’s duration). The Administrative Agent shall promptly give each Lender written notice (or telephonic notice promptly confirmed in writing) of each proposed Borrowing of Loans, of such Lender’s Commitment Percentage thereof and of the other matters covered by the related Notice of Borrowing.

(b)                                 Whenever the Borrower desires to incur Swingline Loans hereunder, it shall give the Administrative Agent written notice (or telephonic notice promptly confirmed in writing) of each Borrowing of Swingline Loans prior to 3:00 p.m. (New York City time) on the date of such Borrowing. Each such notice shall specify (i) the aggregate principal amount of the Swingline Loans to be made pursuant to such Borrowing and (ii) the date of Borrowing (which shall be a Business Day). The Administrative Agent shall promptly give the Swingline Lender written notice (or telephonic notice promptly confirmed in writing) of each proposed Borrowing of Swingline Loans and of the other matters covered by the related Notice of Borrowing.

(c)                                  Mandatory Borrowings shall be made upon the notice specified in Section 2.1(c), with the Borrower irrevocably agreeing, by its incurrence of any Swingline Loan, to the making of Mandatory Borrowings as set forth in such Section.

(d)                                 Borrowings to reimburse Unpaid Drawings shall be made upon the notice specified in Section 3.4(a).

(e)                                  Without in any way limiting the obligation of the Borrower to confirm in writing any notice it may give hereunder by telephone, the Administrative Agent may act prior to receipt of written confirmation without liability upon the basis of such telephonic notice believed by the Administrative Agent in good faith to be from an Authorized Officer of the Borrower.

2.4                               Disbursement of Funds.

(a)                                 No later than 1.00 p.m. (New York City time) on the date specified in each Notice of Borrowing (including Mandatory Borrowings), each Lender will make available its pro

62

rata portion of each Borrowing requested to be made on such date in the manner provided below; provided that on the Closing Date, such funds shall be made available by 10:00 a.m. (New York City time) or such earlier time as may be agreed among the Lenders, the Borrower and the Administrative Agent for the purpose of consummating the Transactions; provided, further, that all Swingline Loans shall be made available in the full amount thereof by the Swingline Lender no later than 3.30 p.m. (New York City time) on the date requested.

(b)                                 Each Lender shall make available all amounts it is to fund to the Borrower under any Borrowing in immediately available funds to the Administrative Agent at the Administrative Agent’s Office in Dollars, and the Administrative Agent will (except in the case of Mandatory Borrowings and Borrowings to repay Unpaid Drawings) make available to the Borrower, by depositing or wiring to an account as designated by the Borrower in the Borrowing Notice to the Administrative Agent the aggregate of the amounts so made available in Dollars. Unless the Administrative Agent shall have been notified by any Lender prior to the date of any such Borrowing (or, with respect to an ABR Loan, the date of such Borrowing prior to 1:00 p.m. (New York City time)) that such Lender does not intend to make available to the Administrative Agent its portion of the Borrowing or Borrowings to be made on such date, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date of Borrowing, and the Administrative Agent, in reliance upon such assumption, may (in its sole discretion and without any obligation to do so) make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Administrative Agent by such Lender and the Administrative Agent has made available such amount to the Borrower, the Administrative Agent shall be entitled to recover such corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor the Administrative Agent shall promptly notify the Borrower and the Borrower shall immediately pay such corresponding amount to the Administrative Agent in Dollars. The Administrative Agent shall also be entitled to recover from such Lender or the Borrower, as the case may be, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Administrative Agent to the Borrower to the date such corresponding amount is recovered by the Administrative Agent, at a rate per annum equal to (i) if paid by such Lender, the Overnight Rate or (ii) if paid by the Borrower, the then-applicable rate of interest or fees, calculated in accordance with Section 2.8, for the respective Loans.

(c)                                  Nothing in this Section 2.4 shall be deemed to relieve any Lender from its obligation to fulfill its commitments hereunder or to prejudice any rights that the Borrower may have against any Lender as a result of any default by such Lender hereunder (it being understood, however, that no Lender shall be responsible for the failure of any other Lender to fulfill its commitments hereunder).

2.5                               Repayment of Loans; Evidence of Debt.

(a)                                 The Borrower agrees to repay to the Administrative Agent, for the benefit of the applicable Lenders, (i) on the Initial Maturity Date, the then outstanding Initial Loans, (ii) on the relevant maturity date for any Extension Series of Extended Commitments, all then

63

outstanding Extended Loans in respect of such Extension Series and (iii) on the Swingline Maturity Date, the then outstanding Swingline Loans.

(b)                                 Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to the appropriate lending office of such Lender resulting from each Loan made by such lending office from time to time, including the amounts of principal and interest payable and paid to such lending office from time to time under this Agreement.

(c)                                  The Administrative Agent, on behalf of the Borrower, shall maintain the Register pursuant to Section 13.6(b), and a subaccount for each Lender, in which Register and subaccounts (taken together) shall be recorded (i) the amount of each Loan made hereunder (whether such Loan is an Initial Loan, an Extended Loan or Swingline Loan, as applicable), the Type of each Loan made and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender or the Swingline Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder from the Borrower and each Lender’s share thereof.

(d)                                 The entries made in the Register and accounts and subaccounts maintained pursuant to clauses (b) and (c) of this Section 2.5 shall, to the extent permitted by applicable Requirements of Law, be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of any Lender or the Administrative Agent to maintain such account, such Register or such subaccount, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrower to repay (with applicable interest) the Loans made to the Borrower by such Lender in accordance with the terms of this Agreement.

2.6                               Conversions and Continuations.

(a)                                 Subject to the penultimate sentence of this clause (a), (i) the Borrower shall have the option on any Business Day to convert all or a portion equal to at least the Minimum Borrowing Amount (and in multiples of $100,000 in excess thereof) of the outstanding principal amount of Loans of one Type into a Borrowing or Borrowings of another Type and (ii) the Borrower shall have the option on any Business Day to continue the outstanding principal amount of any LIBOR Loans as LIBOR Loans for an additional Interest Period; provided that (A) no partial conversion of LIBOR Loans shall reduce the outstanding principal amount of LIBOR Loans made pursuant to a single Borrowing to less than the Minimum Borrowing Amount, (B) ABR Loans may not be converted into LIBOR Loans if an Event of Default is in existence on the date of the conversion and the Administrative Agent has or the Majority Lenders have determined in its or their sole discretion not to permit such conversion, (C) LIBOR Loans may not be continued as LIBOR Loans for an additional Interest Period if an Event of Default is in existence on the date of the proposed continuation and the Administrative Agent has or the Majority Lenders have determined in its or their sole discretion not to permit such continuation, and (D) Borrowings resulting from conversions pursuant to this Section 2.6 shall be limited in number as provided in Section 2.2. Each such conversion or continuation shall be effected by the Borrower by giving the Administrative Agent at the Administrative Agent’s Office prior to 1:00 p.m. (New York City time) at least (1) three Business Days’, in the case of a continuation of

64

or conversion to LIBOR Loans or (2) the date of conversion, in the case of a conversion into ABR Loans, prior written notice (or telephonic notice promptly confirmed in writing) (each, a “Notice of Conversion or Continuation”) specifying the Loans to be so converted or continued, the Type of Loans to be converted into or continued and, if such Loans are to be converted into or continued as LIBOR Loans, the Interest Period to be initially applicable thereto (if no Interest Period is selected, the Borrower shall be deemed to have selected an Interest Period of one month’s duration). The Administrative Agent shall give each applicable Lender notice as promptly as practicable of any such proposed conversion or continuation affecting any of its Loans.

(b)                                 If any Event of Default is in existence at the time of any proposed continuation of any LIBOR Loans and the Administrative Agent has or the Majority Lenders have determined in its or their sole discretion not to permit such continuation, such LIBOR Loans shall be automatically converted on the last day of the current Interest Period into ABR Loans. If upon the expiration of any Interest Period in respect of LIBOR Loans, the Borrower has failed to elect a new Interest Period to be applicable thereto as provided in clause (a) above, the Borrower shall be deemed to have elected to convert such Borrowing of LIBOR Loans into a Borrowing of ABR Loans, effective as of the expiration date of such current Interest Period.

(c)                                  Notwithstanding anything to the contrary herein, the Borrower may deliver a Notice of Conversion or Continuation pursuant to which the Borrower elects to irrevocably continue the outstanding principal amount of any Loan subject to an interest rate Hedge Agreement as LIBOR Loans for each Interest Period until the expiration of the term of such applicable Hedge Agreement; provided that any Notice of Conversion or Continuation delivered pursuant to this Section 2.6(c) shall include a schedule attaching the relevant interest rate Hedge Agreement or related trade confirmation.

2.7                               Pro Rata Borrowings. Each Borrowing of Initial Loans under this Agreement shall be made by the Lenders pro rata on the basis of their then applicable Commitment Percentages with respect to the applicable Class. Each Borrowing of Extended Loans under this Agreement shall be granted by the Lenders of the relevant Extension Series thereof pro rata on the basis of their then-applicable Extended Commitments for the applicable Extension Series. It is understood that (a) no Lender shall be responsible for any default by any other Lender in its obligation to make Loans hereunder and that each Lender severally but not jointly shall be obligated to make the Loans provided to be made by it hereunder, regardless of the failure of any other Lender to fulfill its commitments hereunder and (b) failure by a Lender to perform any of its obligations under any of the Credit Documents shall not release any Person from performance of its obligation under any Credit Document.

65

2.8                               Interest.

(a)                                 The unpaid principal amount of each ABR Loan shall bear interest from the date of the Borrowing thereof until maturity (whether by acceleration or otherwise) at a rate per annum that shall at all times be the Applicable Margin plus the ABR, in each case, in effect from time to time.

(b)                                 The unpaid principal amount of each LIBOR Loan shall bear interest from the date of the Borrowing thereof until maturity thereof (whether by acceleration or otherwise) at a rate per annum that shall at all times be the Applicable Margin plus the relevant LIBOR Rate, in each case, in effect from time to time.

(c)                                  If all or a portion of (i) the principal amount of any Loan or (ii) any interest payable thereon shall not be paid when due (whether at stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum that is (the “Default Rate”) (A) in the case of overdue principal, the rate that would otherwise be applicable thereto plus 2% or (B) in the case of any overdue interest, to the extent permitted by applicable Requirements of Law, the rate described in Section 2.8(a) plus 2% from the date of such nonpayment to the date on which such amount is paid in full (after as well as before judgment).

(d)                                 Interest on each Loan shall accrue from and including the date of any Borrowing to but excluding the date of any repayment thereof and shall be payable in Dollars; provided that any Loan that is repaid on the same date on which it is made shall bear interest for one day. Except as provided below, interest shall be payable (i) in respect of each ABR Loan, quarterly in arrears on the last Business Day of each March, June, September and December, (ii) in respect of each LIBOR Loan, on the last day of each Interest Period applicable thereto and, in the case of an Interest Period in excess of three months, on each date occurring at three-month intervals after the first day of such Interest Period, (iii) in respect of each Loan, (A) on any prepayment (on the amount prepaid), (B) at maturity (whether by acceleration or otherwise) and (C) after such maturity, on demand.

(e)                                  All computations of interest hereunder shall be made in accordance with Section 5.5.

(f)                                   The Administrative Agent, upon determining the interest rate for any Borrowing of LIBOR Loans, shall promptly notify the Borrower and the relevant Lenders thereof. Each such determination shall, absent clearly demonstrable error, be final and conclusive and binding on all parties hereto.

2.9                               Interest Periods. At the time the Borrower gives a Notice of Borrowing or Notice of Conversion or Continuation in respect of the making of, or conversion into or continuation as, a Borrowing of LIBOR Loans in accordance with Section 2.6(a), the Borrower shall give the Administrative Agent written notice (or telephonic notice promptly confirmed in writing) of the Interest Period applicable to such Borrowing, which Interest Period shall, at the option of the Borrower be (i) a one-, two-, three- or six- or (if available to all the Lenders making such LIBOR Loans as determined by such Lenders in good faith based on prevailing market conditions) a nine- or twelve-month period or (ii) any period shorter than one month (if available

66

to all the Lenders making such LIBOR Loans as determined by such Lenders in good faith based on prevailing market conditions) as requested by the Borrower.

Notwithstanding anything to the contrary contained above:

(a)                                 the initial Interest Period for any Borrowing of LIBOR Loans shall commence on the date of such Borrowing (including the date of any conversion from a Borrowing of ABR Loans) and each Interest Period occurring thereafter in respect of such Borrowing shall commence on the day on which the next preceding Interest Period expires;

(b)                                 if any Interest Period relating to a Borrowing of LIBOR Loans begins on the last Business Day of a calendar month or begins on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period, such Interest Period shall end on the last Business Day of the calendar month at the end of such Interest Period;

(c)                                  if any Interest Period would otherwise expire on a day that is not a Business Day, such Interest Period shall expire on the next succeeding Business Day; provided that, if any Interest Period in respect of a LIBOR Loan would otherwise expire on a day that is not a Business Day, but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall expire on the next preceding Business Day; and

(d)                                 the Borrower shall not be entitled to elect any Interest Period in respect of any LIBOR Loan if such Interest Period would extend beyond the Maturity Date.

2.10                        Increased Costs, Illegality, Etc.

(a)                                 In the event that (x) in the case of clause (i) below, the Majority Lenders or (y) in the case of clauses (ii) and (iii) below, any Lender, shall have reasonably determined (which determination shall, absent clearly demonstrable error, be final and conclusive and binding upon all parties hereto):

(i)                                     on any date for determining the LIBOR Rate for any Interest Period that (A) deposits in the principal amounts of the Loans comprising such LIBOR Borrowing are not generally available in the relevant market or (B) by reason of any changes arising on or after the Closing Date affecting the interbank LIBOR market, adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the definition of LIBOR Rate; or

(ii)                                  that, due to a Change in Law occurring at any time after the Closing Date, which Change in Law shall (A) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender, (B) subject any Lender to any Tax with respect to any Credit Document or any LIBOR Loan made by it (other than (i) Taxes indemnifiable under Section 5.4, or (ii) Excluded Taxes), or

67

(C) impose on any Lender or the London interbank market any other condition, cost or expense affecting this Agreement or LIBOR Loans made by such Lender, which results in the cost to such Lender of making, converting into, continuing or maintaining LIBOR Loans or participating in Letters of Credit (in each case hereunder) increasing by an amount which such Lender reasonably deems material or the amounts received or receivable by such Lender hereunder with respect to the foregoing shall be reduced; or

(iii)                               at any time, that the making or continuance of any LIBOR Loan has become unlawful as a result of compliance by such Lender in good faith with any Requirement of Law (or would conflict with any such Requirement of Law not having the force of law even though the failure to comply therewith would not be unlawful);

then, and in any such event, such Lenders (or the Administrative Agent, in the case of clause (i) above) shall within a reasonable time thereafter give notice (if by telephone, confirmed in writing) to the Borrower and to the Administrative Agent of such determination (which notice the Administrative Agent shall promptly transmit to each of the other Lenders). Thereafter (x) in the case of clause (i) above, LIBOR Loans shall no longer be available until such time as the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice by the Administrative Agent no longer exist (which notice the Administrative Agent agrees to give at such time when such circumstances no longer exist), and any Notice of Borrowing or Notice of Conversion given by the Borrower with respect to LIBOR Loans that have not yet been incurred shall be deemed rescinded by the Borrower, (y) in the case of clause (ii) above, the Borrower shall pay to such Lender, promptly (but no later than fifteen days) after receipt of written demand therefor such additional amounts as shall be required to compensate such Lender for such increased costs or reductions in amounts receivable hereunder (it being agreed that a written notice as to the additional amounts owed to such Lender, showing in reasonable detail the basis for the calculation thereof, submitted to the Borrower by such Lender shall, absent clearly demonstrable error, be final and conclusive and binding upon all parties hereto) and (z) in the case of clause (iii) above, the Borrower shall take one of the actions specified in Section 2.10(b) as promptly as possible and, in any event, within the time period required by applicable Requirements of Law.

(b)                                 At any time that any LIBOR Loan is affected by the circumstances described in Section 2.10(a)(ii) or (iii), the Borrower may (and in the case of a LIBOR Loan affected pursuant to Section 2.10(a)(iii) shall) either if the affected LIBOR Loan is then being made pursuant to a Borrowing, cancel such Borrowing by giving the Administrative Agent telephonic notice (confirmed promptly in writing) thereof on the same date that the Borrower was notified by a Lender pursuant to Section 2.10(a)(ii) or (iii) or if the affected LIBOR Loan is then outstanding, upon at least three Business Days’ notice to the Administrative Agent, require the affected Lender to convert each such LIBOR Loan into an ABR Loan; provided that if more than one Lender are affected at any time, then all affected Lenders must be treated in the same manner pursuant to this Section 2.10(b).

(c)                                  If, after the Closing Date, any Change in Law relating to capital adequacy or liquidity requirements of any Lender or compliance by any Lender or its parent with any Change in Law relating to capital adequacy or liquidity requirements occurring after the Closing

68

Date, has or would have the effect of reducing the rate of return on such Lender’s or its parent’s capital or assets as a consequence of such Lender’s commitments or obligations hereunder to a level below that which such Lender or its parent could have achieved but for such Change in Law (taking into consideration such Lender’s or its parent’s policies with respect to capital adequacy or liquidity requirements), then from time to time, promptly (but in any event no later than fifteen days) after written demand by such Lender (with a copy to the Administrative Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender or its parent for such reduction, it being understood and agreed, however, that a Lender shall not be entitled to such compensation as a result of such Lender’s compliance with, or pursuant to any request or directive to comply with, any applicable Requirement of Law as in effect on the Closing Date. Each Lender, upon determining in good faith that any additional amounts will be payable pursuant to this Section 2.10(c), will give prompt written notice thereof to the Borrower, which notice shall set forth in reasonable detail the basis of the calculation of such additional amounts, although the failure to give any such notice shall not, subject to Section 2.13, release or diminish the Borrower’s obligations to pay additional amounts pursuant to this Section 2.10(c) upon receipt of such notice.

2.11                        Compensation. If (a) any payment of principal of any LIBOR Loan is made by the Borrower to or for the account of a Lender other than on the last day of the Interest Period for such LIBOR Loan as a result of a payment or conversion pursuant to Section 2.5, 2.6, 2.10, 5.1, 5.2 or 13.7, as a result of acceleration of the maturity of the Loans pursuant to Section 11 or for any other reason, (b) any Borrowing of LIBOR Loans is not made on the date specified in a Notice of Borrowing, (c) any ABR Loan is not converted into a LIBOR Loan on the date specified in a Notice of Conversion or Continuation, (d) any LIBOR Loan is not continued as a LIBOR Loan on the date specified in a Notice of Conversion or Continuation or (e) any prepayment of principal of any LIBOR Loan is not made as a result of a withdrawn notice of prepayment pursuant to Section 5.1 or 5.2, the Borrower shall after the Borrower’s receipt of a written request by such Lender (which request shall set forth in reasonable detail the basis for requesting such amount), pay to the Administrative Agent (within fifteen days after such request) for the account of such Lender any amounts required to compensate such Lender for any additional losses, costs or expenses that such Lender may reasonably incur as a result of such payment, failure to convert, failure to continue or failure to prepay, including any loss, cost or expense (excluding loss of anticipated profits) actually incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such LIBOR Loan.

2.12                        Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.10(a)(ii), 2.10(a)(iii), 2.10(c), 3.5 or 5.4 with respect to such Lender, it will, if requested by the Borrower use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected by such event; provided that such designation does not cause such Lender or its lending office to suffer any economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of any such Section. Nothing in this Section 2.12 shall affect or postpone any of the obligations of the Borrower or the right of any Lender provided in Section 2.10, 3.5 or 5.4.

69

2.13                        Notice of Certain Costs. Notwithstanding anything in this Agreement to the contrary, to the extent any notice required by Section 2.10, 2.11, 3.5 or 5.4 is given by any Lender more than 180 days after such Lender has knowledge (or should have had knowledge) of the occurrence of the event giving rise to the additional cost, reduction in amounts, loss, tax or other additional amounts described in such Sections, such Lender shall not be entitled to compensation under Section 2.10, 2.11, 3.5 or 5.4, as the case may be, for any such amounts incurred or accruing prior to the 181st day prior to the giving of such notice to the Borrower; provided that if the circumstance giving rise to such claim is retroactive, then such 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

2.14                        Borrowing Base.

(a)                                 Initial Borrowing Base. For the period from and including the Closing Date to but excluding the first Redetermination Date, the amount of the Borrowing Base shall be $2,000,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from time to time pursuant to Section 2.14(e), (f), (g) and (h).

(b)                                 Scheduled and Interim Redeterminations. The Borrowing Base shall be redetermined semi-annually in accordance with this Section 2.14 (a “Scheduled Redetermination”), and, subject to Section 2.14(d), such redetermined Borrowing Base shall become effective and applicable to the Borrower, the Administrative Agent, the Issuing Banks and the Lenders on April 30th (or April 1, 2013 with respect to the first Scheduled Redetermination) and October 31st of each year (or as promptly as possible thereafter), commencing 2013. In addition, the Borrower may at any time (including prior to the first Scheduled Redetermination date of April 1, 2013), by notifying the Administrative Agent thereof not more than twice during any period of 12 consecutive calendar months, and the Administrative Agent, following the first Scheduled Redetermination date of April 1, 2013, may, at the direction of the Required Lenders, by notifying the Borrower thereof, one time during any period of 12 consecutive calendar months, in each case elect to cause the Borrowing Base to be redetermined between Scheduled Redeterminations (an “Interim Redetermination”) in accordance with this Section 2.14; provided that the Required Lenders may direct the Administrative Agent to initiate an Interim Redetermination prior to the first Scheduled Redetermination of April 1, 2013 in the event that the Hedging Condition is not satisfied (in which case, such Interim Redetermination shall not count against the first such Interim Redetermination otherwise permitted to be initiated pursuant to this Section 2.14(b) by the Administrative Agent). In addition to, and not including and/or limited by the annual Interim Redeterminations allowed above, the Borrower may, by notifying the Administrative Agent thereof, at any time between Scheduled Redeterminations, request additional Interim Redeterminations of the Borrowing Base in the event it acquires Oil and Gas Properties with Proved Reserves which are to be Borrowing Base Properties having a PV-10 (calculated at the time of acquisition) in excess of 5% of the Borrowing Base in effect immediately prior to such acquisition.

(c)                                  Scheduled and Interim Redetermination Procedure.

(i)                                     Each Scheduled Redetermination and each Interim Redetermination shall be effectuated as follows: Upon receipt by the Administrative Agent of (A) the Reserve Report and the Reserve Report Certificate, and (B) such other reports, data and supplemental information, including the information provided pursuant to

70

Section 9.14(c), as may, from time to time, be reasonably requested by the Required Lenders (the Reserve Report, such Reserve Report Certificate and such other reports, data and supplemental information being the “Engineering Reports”), the Administrative Agent shall evaluate the information contained in the Engineering Reports and shall in good faith propose a new Borrowing Base (the “Proposed Borrowing Base”) based upon such information and such other information (including the status of title information with respect to the Borrowing Base Properties as described in the Engineering Reports and the existence of any Hedge Agreements or any other Indebtedness) as the Administrative Agent deems appropriate in good faith in accordance with its usual and customary oil and gas lending criteria as they exist at the particular time.

(ii)                                  The Administrative Agent shall notify the Borrower and the Lenders of the Proposed Borrowing Base (the “Proposed Borrowing Base Notice”):

(A)                               in the case of a Scheduled Redetermination, (1) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Sections 9.14(a) and (c) in a timely manner, then on or before the April 15th and October 15th of such year following the date of delivery or (2) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Sections 9.14(a) and (c) in a timely manner, then promptly after the Administrative Agent has received complete Engineering Reports from the Borrower and has had a reasonable opportunity to determine the Proposed Borrowing Base in accordance with Section 2.14(c)(i); and

(B)                               in the case of an Interim Redetermination, promptly, and in any event, within 15 days after the Administrative Agent has received the required Engineering Reports.

(iii)                               Any Proposed Borrowing Base that would increase the Borrowing Base then in effect must be approved or deemed to have been approved by the Borrowing Base Required Lenders in each such Lender’s sole discretion and consistent with each such Lender’s normal and customary oil and gas lending criteria as they exist at the particular time as provided in this Section 2.14(c)(iii) and any Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect must be approved or be deemed to have been approved by Lenders constituting at least the Required Lenders in each such Lender’s sole discretion and consistent with each such Lender’s normal and customary oil and gas lending criteria as they exist at the particular time as provided in this Section 2.14(c)(iii). Upon receipt of the Proposed Borrowing Base Notice, each Lender shall have 15 days to agree with the Proposed Borrowing Base or disagree with the Proposed Borrowing Base by proposing an alternate Borrowing Base. If at the end of such 15-day period, any Lender has not communicated its approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be an approval of the Proposed Borrowing Base. If, at the end of such 15-day period, the Borrowing Base Required Lenders, in the case of a Proposed Borrowing Base that would increase the Borrowing Base then in effect, or the Required Lenders, in the case of a Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect, have approved

71

or deemed to have approved, as aforesaid, then the Proposed Borrowing Base shall become the new Borrowing Base, effective on the date specified in Section 2.14(d). If, however, at the end of such 15-day period, the Borrowing Base Required Lenders or the Required Lenders, as applicable, have not approved or deemed to have approved, as aforesaid, then the Administrative Agent shall promptly thereafter poll the Lenders to ascertain the highest Borrowing Base then acceptable to the Borrowing Base Required Lenders (in the case of any increase to the Borrowing Base) or a number of Lenders sufficient to constitute the Required Lenders (in any other case) and such amount shall be come the new Borrowing Base, effective on the date specified in Section 2.14(d).

(d)                                 Effectiveness of a Redetermined Borrowing Base. Subject to Section 2.14(h), after a redetermined Borrowing Base is approved or is deemed to have been approved by the Borrowing Base Required Lenders or the Required Lenders, as applicable, pursuant to Section 2.14(c)(iii), the Administrative Agent shall promptly thereafter notify the Borrower and the Lenders of the amount of the redetermined Borrowing Base (the “New Borrowing Base Notice”), and such amount shall become the new Borrowing Base, effective and applicable to the Borrower, the Administrative Agent, the Issuing Banks and the Lenders:

(i)                                in the case of a Scheduled Redetermination, (A) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Sections 9.14(a) and (c) in a timely and complete manner, on the April 30th or October 31st, as applicable, following such notice, or (B) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Sections 9.14(a) and (c) in a timely and complete manner, then on the Business Day next succeeding delivery of such New Borrowing Base Notice; and

(ii)                             in the case of an Interim Redetermination, on the Business Day next succeeding delivery of such New Borrowing Base Notice.

Subject to Section 2.14(h), such amount shall then become the Borrowing Base until the next Scheduled Redetermination Date, the next Interim Redetermination Date or the next adjustment to the Borrowing Base under Section 2.14(e), (f), (g) or (h), whichever occurs first. Notwithstanding the foregoing, no Scheduled Redetermination or Interim Redetermination shall become effective until the New Borrowing Base Notice related thereto is received by the Borrower.

(e)                                  Reduction of Borrowing Base Upon Incurrence of Permitted Additional Debt.

(i)                                     Upon the issuance or incurrence of any Permitted Additional Debt in accordance with Section 10.1(p) (other than (x) Permitted Additional Debt constituting Permitted Refinancing Indebtedness incurred to Refinance such Indebtedness, but only to the extent that the aggregate principal amount of Permitted Refinancing Indebtedness incurred to Refinance such Indebtedness does not result in an increase in the principal amount thereof above the principal amount originally incurred or issued up to the original principal amount of the Refinanced Indebtedness and (y) Permitted Additional Debt that is secured by a Junior Lien on the Collateral pursuant to Section 10.2(x) or (z)), the

72

Borrowing Base then in effect shall be reduced by an amount equal to the product of 0.25 multiplied by the stated principal amount of such Permitted Additional Debt (without regard to any original issue discount), and the Borrowing Base as so reduced shall become the new Borrowing Base immediately upon the date of such issuance or incurrence, effective and applicable to the Borrower, the Administrative Agent, the Issuing Banks and the Lenders on such date until the next redetermination or modification thereof hereunder.

(ii)                                  Upon the issuance or incurrence of any Indebtedness (including any Permitted Additional Debt) that is secured by Junior Liens on the Collateral pursuant to Section 10.2(x) or (z) (other than Indebtedness constituting Permitted Refinancing Indebtedness incurred to Refinance such Indebtedness, but only to the extent that the aggregate principal amount of Permitted Refinancing Indebtedness incurred to Refinance such Indebtedness does not result in an increase in the principal amount thereof above the principal amount originally incurred or issued up to the original principal amount of the Refinanced Indebtedness), the Borrowing Base then in effect shall be reduced by an amount equal to the product of 0.30 multiplied by the stated principal amount of such Indebtedness (without regard to any original issue discount), and the Borrowing Base as so reduced shall become the new Borrowing Base immediately upon the date of such issuance or incurrence, effective and applicable to the Borrower, the Administrative Agent, the Issuing Banks and the Lenders on such date until the next redetermination or modification thereof hereunder.

(f)                              Reduction of Borrowing Base Upon Termination of Hedge Positions. If the Borrower or any Restricted Subsidiary shall terminate or create any off-setting positions in respect of any commodity hedge positions (whether evidenced by a floor, put or Hedge Agreement) upon which (i) the Lenders relied in determining the Borrowing Base and (ii) the Borrowing Base Value of such terminated and/or offsetting positions (after taking into account any other Hedge Agreement, executed contemporaneously with the taking of such actions) exceeds 10% of the then-effective Borrowing Base, then, the Required Lenders shall have the right to adjust the Borrowing Base in an amount equal to the Borrowing Base Value, if any, attributable to such terminated or off-setting hedge positions in the calculation of the then-effective Borrowing Base and (if the Required Lenders in fact make any such adjustment) the Administrative Agent shall promptly notify the Borrower in writing of the Borrowing Base Value, if any, attributable to such hedge positions in the calculation of the then-effective Borrowing Base and upon receipt of such notice, the Borrowing Base shall be simultaneously reduced by such amount.

(g)                             Reduction of Borrowing Base Upon Asset Dispositions. If (i) the Borrower or one of the other Credit Parties Disposes of Oil and Gas Properties or Disposes of any Equity Interests in any Restricted Subsidiary or Minority Investment owning Oil and Gas Properties and none of the foregoing Dispositions is a Scheduled Disposition, (ii) such Disposition described in clause (i) involves Borrowing Base Properties included in the most recently delivered Reserve Report and (iii) the aggregate Borrowing Base Value of all such Borrowing Base Properties Disposed of (except in connection with a Scheduled Disposition) since the later of (A) the last Scheduled Redetermination Date and (B) the last adjustment of the Borrowing Base made pursuant to this Section 2.14(g) exceeds 10% of the then-effective Borrowing Base, then, after the Administrative Agent has received the notice required to be delivered by the Borrower

73

pursuant to Section 10.4(b), no later than two Business Days’ after the date of consummation of any such Disposition, the Required Lenders shall have the right to adjust the Borrowing Base in an amount equal to the Borrowing Base Value, if any, attributable to such Disposed of Borrowing Base Properties in the calculation of the then-effective Borrowing Base and, if the Required Lenders in fact make any such adjustment, the Administrative Agent shall promptly notify the Borrower in writing of the Borrowing Base Value, if any, attributable to such Disposed of Borrowing Base Properties in the calculation of the then-effective Borrowing Base and upon receipt of such notice, the Borrowing Base shall be simultaneously reduced by such amount.

(h)                            Borrower’s Right to Elect Reduced Borrowing Base. Within three Business Days of its receipt of a New Borrowing Base Notice, the Borrower may provide written notice to the Administrative Agent and the Lenders that specifies for the period from the effective date of the New Borrowing Base Notice until the next succeeding Scheduled Redetermination Date, the Borrowing Base will be a lesser amount than the amount set forth in such New Borrowing Base Notice, whereupon such specified lesser amount will become the new Borrowing Base. The Borrower’s notice under this Section 2.14(h) shall be irrevocable, but without prejudice to its rights to initiate Interim Redeterminations.

(i)                                Administrative Agent Data. The Administrative Agent hereby agrees to provide, promptly, and in any event within 3 Business Days, following its receipt of a request by the Borrower, an updated Bank Price Deck. In addition, the Administrative Agent and the Lenders agree, upon request, to meet with the Borrower to discuss their evaluation of the reservoir engineering of the Oil and Gas Properties included in the Reserve Report and their respective methodologies for valuing such properties and the other factors considered in calculating the Borrowing Base.

2.15                        Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(a)                                 Commitment Fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender pursuant to Section 4.1(a);

(b)                                 The Commitment and Total Exposure of such Defaulting Lender shall not be included in determining whether all Lenders, the Majority Lenders or the Required Lenders or Borrowing Base Required Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 13.1); provided that (i) any waiver, amendment or modification requiring the consent of all Lenders pursuant to Section 13.1 (other than Section 13.1(x)) or requiring the consent of each affected Lender pursuant to Section 13.1(i) or (ix) shall require the consent of such Defaulting Lender (which for the avoidance of doubt would include any change to the Maturity Date applicable to such Defaulting Lender, decreasing or forgiving any principal or interest due to such Defaulting Lender, any decrease of any interest rate applicable to Loans made by such Defaulting Lender (other than the waiving of post-default interest rates) and any increase in such Defaulting Lender’s Commitment) and (ii) any redetermination, whether an increase, decrease or affirmation, of the Borrowing Base shall occur without the participation of a Defaulting Lender, but the Commitment (i.e., the Commitment

74

Percentage of the Borrowing Base) of a Defaulting Lender may not be increased without the consent of such Defaulting Lender;

(c)                                  If any Swingline Exposure or Letter of Credit Exposure exists at the time a Lender becomes a Defaulting Lender, then all or any part of such Swingline Exposure and Letter of Credit Exposure of such Defaulting Lender will, subject to the limitation in the first proviso below, automatically be reallocated (effective on the day such Lender becomes a Defaulting Lender) among the Non-Defaulting Lenders pro rata in accordance with their respective Commitment Percentages; provided that (A) each Non-Defaulting Lender’s Total Exposure may not in any event exceed the Commitment Percentage of the Loan Limit of such Non-Defaulting Lender as in effect at the time of such reallocation and (B) neither such reallocation nor any payment by a Non-Defaulting Lender pursuant thereto will constitute a waiver or release of any claim the Borrower, the Administrative Agent, the Issuing Banks or any other Lender may have against such Defaulting Lender or cause such Defaulting Lender to be a Non-Defaulting Lender, to the extent that all or any portion (the “unreallocated portion”) of the Defaulting Lender’s Swingline Exposure or Letter of Credit Exposure cannot, or can only partially, be so reallocated to Non-Defaulting Lenders, whether by reason of the first proviso in Section 2.15(c)(i) or otherwise, the Borrower shall within two Business Days following notice by the Administrative Agent (x) first, prepay such Swingline Exposure and (y) second, Cash Collateralize for the benefit of the applicable Issuing Bank only the Borrower’s obligations corresponding to such Defaulting Lender’s Letter of Credit Exposure (after giving effect to any partial reallocation pursuant to clause (i) above), in accordance with the procedures set forth in Section 3.8 for so long as such Letter of Credit Exposure is outstanding, if the Borrower Cash Collateralizes any portion of such Defaulting Lender’s Letter of Credit Exposure pursuant to this Section 2.15(c), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 4.1(b) with respect to such Defaulting Lender’s Letter of Credit Exposure during the period such Defaulting Lender’s Letter of Credit Exposure is Cash Collateralized, if the Letter of Credit Exposure of the Non- Defaulting Lenders is reallocated pursuant to this Section 2.15(c), then the Letter of Credit Fees payable for the account of the Lenders pursuant to Section 4.1(b) shall be adjusted in accordance with such Non-Defaulting Lenders’ Commitment Percentages and the Borrower shall not be required to pay any Swingline Loan fees (if any) or Letter of Credit Fees to the Defaulting Lender pursuant to Section 4.1(b) with respect to such Defaulting Lender’s Letter of Credit Exposure during the period that such Defaulting Lender’s Letter of Credit Exposure is reallocated, or if any Defaulting Lender’s Letter of Credit Exposure is neither Cash Collateralized nor reallocated pursuant to this Section 2.15(c), then, without prejudice to any rights or remedies of any Issuing Bank or any Lender hereunder, all Letter of Credit Fees payable under Section 4.1(b) with respect to such Defaulting Lender’s Letter of Credit Exposure shall be payable to such Issuing Bank until such Letter of Credit Exposure is Cash Collateralized and/or reallocated;

(d)                                 So long as any Lender is a Defaulting Lender, the Swingline Lender shall not be required to fund any Swingline Loan and no Issuing Bank will be required to issue any new Letter of Credit or amend any outstanding Letter of Credit to increase the Stated Amount thereof, alter the drawing terms thereunder or extend the expiry date thereof,

75

unless each Issuing Bank is reasonably satisfied that any exposure that would result from the exposure to such Defaulting Lender is eliminated or fully covered by the Commitments of the Non-Defaulting Lenders or by Cash Collateralization or a combination thereof in accordance with clause (c) above or otherwise in a manner reasonably satisfactory to such Issuing Bank, and participating interests in any such newly issued or increased Letter of Credit or newly made Swingline Loan shall be allocated among Non-Defaulting Lenders in a manner consistent with Section 2.15(c)(i) (and Defaulting Lenders shall not participate therein); and

(e)                                  If the Borrower, the Administrative Agent, the Swingline Lender and each Issuing Bank agree in writing in their discretion that a Lender that is a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon, as of the effective date specified in such notice and subject to any conditions set forth therein, such Lender will cease to be a Defaulting Lender and will be a Non-Defaulting Lender and any applicable Cash Collateral shall be promptly returned to the Borrower and any Letter of Credit Exposure of such Lender reallocated pursuant to Section 2.15(c) shall be reallocated back to such Lender; provided that, except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender.

(f)                                   Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of that Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Section 11 or otherwise, and including any amounts made available to the Administrative Agent by that Defaulting Lender pursuant to Section 13.8), shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by that Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by that Defaulting Lender to each Issuing Bank and the Swingline Lender hereunder; third, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which that Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fourth, if so determined by the Administrative Agent and the Borrower, to be held in a non-interest bearing deposit account and released in order to satisfy obligations of that Defaulting Lender to fund Loans under this Agreement; fifth, to the payment of any amounts owing to the Lenders, each Issuing Bank or the Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, such Issuing Bank or the Swingline Lender against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; sixth, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; and seventh, to that Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if such payment is a payment of the principal amount of any Loans or Unpaid Drawings, such payment shall

76

be applied solely to pay the relevant Loans of, and Unpaid Drawings owed to, the relevant non-Defaulting Lenders on a pro rata basis prior to being applied in the manner set forth in this Section 2.15(f). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to Section 3.8 shall be deemed paid to and redirected by that Defaulting Lender, and each Lender irrevocably consents hereto.

2.16                        Increase of Total Commitment.

(a)                                 Subject to the conditions set forth in Section 2.16(b), the Borrower may increase the Total Commitment then in effect (any such increase an “Incremental Increase”) by increasing the Commitment of a Lender (an “Increasing Lender”) or by causing a Person that at such time is not a Lender to become a Lender (an “Additional Lender”).

(b)                                 Any increase in the Total Commitment shall be subject to the following additional conditions:

(i)                                     such increase shall not be less than $10,000,000 (and increments of $1,000,000 above that minimum) unless the Administrative Agent otherwise consents, and no such increase shall be permitted if after giving effect thereto the Total Commitment would exceed $4,000,000,000;

(ii)                                  no Event of Default shall have occurred and be continuing after giving effect to such increase;

(iii)                               no Lender’s Commitment may be increased without the consent of such Lender;

(iv)                              the Administrative Agent, the Swingline Lender and each Issuing Bank must consent to the increase in Commitments of an Increasing Lender and the addition of any Additional Lender, in each case, such consent not to be unreasonably withheld or delayed;

(v)                                 the maturity date of such increase shall be the same as the Maturity Date; and

(vi)                              the increase shall be on the exact same terms and pursuant to the exact same documentation applicable to this Agreement (other than with respect to any arrangement, structuring, upfront or other fees or discounts payable in connection with such Incremental Increase) (provided that the Applicable Margin of the Facility may be increased to be consistent with that for such Incremental Increases).

(c)                                  Any increase in the Total Commitment shall be implemented using customary documentation (any such documentation, an “Incremental Agreement”).

77

2.17                        Extension Offers.

(a)                                 The Borrower may at any time and from time to time request that all or a portion of the Commitments of any Class, existing at the time of such request (each, an “Existing Commitment” and any related revolving credit loans under any such facility, “Existing Loans”; each Existing Commitment and related Existing Loans together being referred to as an “Existing Class”) be converted to extend the termination date thereof and the scheduled maturity date(s) of any payment of principal with respect to all or a portion of any principal amount of Existing Loans related to such Existing Commitments (any such Existing Commitments which have been so Extended, “Extended Commitments” and any related revolving credit loans, “Extended Loans”) and to provide for other terms consistent with this Section 2.17. Prior to entering into any Extension Amendment with respect to any Extended Commitments, the Borrower shall provide a notice to the Administrative Agent (who shall provide a copy of such notice to each of the Lenders of the applicable Class of Existing Commitments and which such request shall be offered equally to all Lenders under such Class) (an “Extension Request”) setting forth the proposed terms of the Extended Commitments to be established thereunder, which terms shall be substantially similar to those applicable to the Existing Commitments from which they are to be Extended (the “Specified Existing Commitment Class”), except that (w) all or any of the final maturity dates of such Extended Commitments may be delayed to later dates than the final maturity dates of the Existing Commitments of the Specified Existing Commitment Class, (x)(A) the interest rates, interest margins, rate floors, upfront fees, funding discounts, original issue discounts and premiums with respect to the Extended Commitments may be different from those for the Existing Commitments of the Specified Existing Commitment Class and/or (B) additional fees and/or premiums may be payable to the Lenders providing such Extended Commitments in addition to or in lieu of any of the items contemplated by the preceding clause (A), (y)(1) the undrawn revolving credit commitment fee rate with respect to the Extended Commitments may be different from such rate for Existing Commitments of the Specified Existing Commitment Class and (2) the Extension Amendment may provide for other covenants and terms that apply to any period after the Latest Maturity Date in effect at such time; provided that, notwithstanding anything to the contrary in this Section 2.17 or otherwise, (1) the borrowing and repayment (other than in connection with a permanent repayment and termination of commitments (which shall be governed by clause (3) below)) of the Extended Loans under any Extended Commitments shall be made on a pro rata basis with any borrowings and repayments of the Existing Loans of the Specified Existing Commitment Class (the mechanics for which may be implemented through the applicable Extension Amendment and may include technical changes related to the borrowing and replacement procedures of the Specified Existing Commitment Class), (2) assignments and participations of Extended Commitments and Extended Loans shall be governed by the assignment and participation provisions set forth in Section 13.6 and (3) subject to the applicable limitations set forth in Section 4.2, permanent repayments of Extended Loans (and corresponding permanent reduction in the related Extended Commitments) shall be permitted as may be agreed upon between the Borrower and the Lenders thereof. No Lender shall have any obligation to agree to have any of its Loans or Commitments of any Existing Class converted into Extended Loans or Extended Commitments pursuant to any Extension Request. Any Extended Commitments of any Extension Series shall constitute a separate Class of revolving credit commitments from Existing Commitments of the Specified Existing Commitment Class and from any other Existing Commitments (together with any other Extended Commitments so established on such date).

78

(b)                                 The Borrower shall provide the applicable Extension Request at least five (5) Business Days (or such shorter period as the Administrative Agent may determine in its reasonable discretion) prior to the date on which Lenders under the Existing Class are requested to respond, and shall agree to such procedures, if any, as may be established by, or acceptable to, the Administrative Agent, in each case acting reasonably, to accomplish the purpose of this Section 2.17. Any Lender (an “Extending Lender”) wishing to have all or a portion of its Commitments (or any earlier Extended Commitments) of an Existing Class subject to such Extension Request converted into Extended Commitments shall notify the Administrative Agent (an “Extension Election”) on or prior to the date specified in such Extension Request of the amount of its Commitments (and/or any earlier Extended Commitments) which it has elected to convert into Extended Commitments (subject to any minimum denomination requirements imposed by the Extension Request). In the event that the aggregate amount of Commitments (and any earlier Extended Commitments) subject to Extension Elections exceeds the amount of Extended Commitments requested pursuant to the Extension Request, Commitments and (and any earlier Extended Commitments) subject to Extension Elections shall be converted to Extended Commitments on a pro rata basis based on the amount of Commitments (and any earlier Extended Commitments) included in each such Extension Election or as may be otherwise agreed to in the applicable Extension Amendment and in the event that the aggregate amount of Commitments (and any earlier Extended Commitments) subject to Extension Elections is less than the amount of Extended Commitments requested pursuant to the Extension Request, the Borrower may cause Additional Lenders to become Extending Lenders hereunder with Extended Commitments by executing an Extension Amendment on the terms specified in such Extension Request in an amount agreed to by such Additional Lenders (the “Additional Lender Extended Amount”) (and in such case the Borrower will either (i) reduce Commitments hereunder (other than Commitments that are subject to Extension Elections pursuant to such Extension Request) by an aggregate amount equal to the Additional Lender Extended Amount, (ii) increase Commitments hereunder by an amount equal to the Additional Lender Extended Amount (up to an aggregate amount not to exceed the amount that would be permitted in an Incremental Increase pursuant to Section 2.16 at such time) or (iii) implement a combination of Commitment reductions under the foregoing clause (i) and Commitment increases under the foregoing clause (ii) in an aggregate amount equal to Additional Lender Extended Amount. Notwithstanding the conversion of any Existing Commitment into an Extended Commitment, such Extended Commitment shall be treated identically to all Existing Commitments of the Specified Existing Commitment Class for purposes of the obligations of a Lender in respect of Swingline Loans under Section 2.1(c) and Letters of Credit under Section 3, except that the applicable Extension Amendment may provide that the Swingline Maturity Date and/or the last day for issuing Letters of Credit may be extended and the related obligations to make Swingline Loans and issue Letters of Credit may be continued (pursuant to mechanics to be specified in the applicable Extension Amendment) so long as the applicable Swingline Lender and/or the applicable Issuing Bank, as applicable, have consented to such extensions (it being understood that no consent of any other Lender shall be required in connection with any such extension).

(c)                                  Extended Commitments shall be established pursuant to an amendment (an “Extension Amendment”) to this Agreement (which, notwithstanding anything to the contrary set forth in Section 13.1, shall not require the consent of any Lender other than the Extending Lenders with respect to the Extended Commitments established thereby) executed by the Credit

79

Parties, the Administrative Agent and the Extending Lenders. It is understood and agreed that each Lender hereunder has consented, and shall at the effective time thereof be deemed to consent to each amendment to this Agreement and the other Credit Documents authorized by this Section 2.17 (and approved by the applicable Extending Lenders with respect to the Extended Commitments established thereby) and the arrangements described above in connection therewith. No Extension Amendment shall provide for any tranche of Extended Commitments in an aggregate principal amount that is less than $200,000,000 (or such lesser amount as the Administrative Agent may agree in its reasonable discretion). Notwithstanding anything to the contrary in this Section 2.17(c) and without limiting the generality or applicability of Section 13.1 to any Section 2.17 Additional Amendments (as defined below), any Extension Amendment may provide for additional terms and/or additional amendments other than those referred to or contemplated above (any such additional amendment, a “Section 2.17 Additional Amendment”) to this Agreement and the other Credit Documents; provided that such Section 2.17 Additional Amendments are within the requirements of Section 2.17(a) and do not become effective prior to the time that such Section 2.17 Additional Amendments have been consented to (including, without limitation, pursuant to consents applicable to holders of any Extended Loans provided for in any Extension Amendment) by such of the Lenders, Credit Parties and other parties (if any) as may be required in order for such Section 2.17 Additional Amendments to become effective in accordance with Section 13.1.

(d)                                 Notwithstanding anything to the contrary contained in this Agreement, (A) on any date on which any Class of Existing Commitments is converted to extend the related scheduled maturity date(s) in accordance with paragraph (a) above (an “Extension Date”), in the case of the Existing Commitments of each Extending Lender under any Specified Existing Commitment Class, the aggregate principal amount of such Existing Commitments shall be deemed reduced by an amount equal to the aggregate principal amount of Extended Commitments so converted by such Lender on such date, and such Extended Commitments shall be established as a separate Class of revolving credit commitments from the Specified Existing Commitment Class and from any other Existing Commitments (together with any other Extended Commitments so established on such date) and (B) if, on any Extension Date, any Existing Loans of any Extending Lender are outstanding under the Specified Existing Commitment Class, such Existing Loans (and any related participations) shall be deemed to be allocated as Extended Loans (and related participations) in the same proportion as such Extending Lender’s Specified Existing Commitments to Extended Commitments.

(e)                                  No exchange of Loans or Commitments pursuant to any Extension Amendment in accordance with this Section 2.17 shall constitute a voluntary or mandatory payment or prepayment for purposes of this Agreement.

SECTION 3.                            Letters of Credit

3.1                               Letters of Credit.

(a)                                 Subject to and upon the terms and conditions herein set forth, at any time and from time to time on and after the Closing Date and prior to the L/C Maturity Date, each Issuing Bank agrees, in reliance upon the agreements of the Lenders set forth in this Section 3, to issue upon the request of the Borrower and for the direct or indirect benefit of the Borrower and

80

the Restricted Subsidiaries, a letter of credit or letters of credit (the “Letters of Credit” and each, a “Letter of Credit”) in such form and with such Issuer Documents as may be approved by the applicable Issuing Bank in its reasonable discretion; provided that the Borrower shall be a co-applicant of, and jointly and severally liable with respect to, each Letter of Credit issued for the account of a Restricted Subsidiary.

(b)                                 Notwithstanding the foregoing, (i) no Letter of Credit shall be issued the Stated Amount of which, when added to the Letters of Credit Outstanding at such time, would exceed the Letter of Credit Commitment then in effect, (ii) no Letter of Credit shall be issued the Stated Amount of which would cause the aggregate amount of all Lenders’ Total Exposures at such time to exceed the Loan Limit then in effect, (iii) each Letter of Credit shall have an expiration date occurring no later than one year after the date of issuance or such longer period of time as may be agreed by the applicable Issuing Bank, unless otherwise agreed upon by the Administrative Agent and the applicable Issuing Bank or as provided under Section 3.2(b); provided that any Letter of Credit may provide for automatic renewal thereof for additional periods of up to 12 months or such longer period of time as may be agreed upon by the applicable Issuing Bank, subject to the provisions of Section 3.2(b); provided, further, that in no event shall such expiration date occur later than the L/C Maturity Date unless arrangements which are reasonably satisfactory to the applicable Issuing Bank to Cash Collateralize (or backstop) such Letter of Credit have been made, (iv) no Alternate Currency Letter of Credit shall be issued if, after giving effect thereto, the aggregate amount of the Letter of Credit Exposure with respect to all Alternate Currency Letters of Credit would exceed $37,500,000, (v) no Letter of Credit shall be issued if it would be illegal under any applicable Requirement of Law for the beneficiary of the Letter of Credit to have a Letter of Credit issued in its favor and (vi) no Letter of Credit shall be issued by an Issuing Bank after it has received a written notice from any Credit Party or the Administrative Agent or the Majority Lenders stating that a Default or Event of Default has occurred and is continuing until such time as such Issuing Bank shall have received a written notice (A) of rescission of such notice from the party or parties originally delivering such notice, (B) of the waiver of such Default or Event of Default in accordance with the provisions of Section 13.1 or (C) that such Default or Event of Default is no longer continuing.

(c)                                  Upon at least one Business Day’s prior written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent and the applicable Issuing Bank (which notice the Administrative Agent shall promptly transmit to each of the applicable Lenders), the Borrower shall have the right, on any day, permanently to terminate or reduce the Letter of Credit Commitment in whole or in part; provided that, after giving effect to such termination or reduction, the Letters of Credit Outstanding shall not exceed the Letter of Credit Commitment.

3.2                               Letter of Credit Applications.

(a)                                 Whenever the Borrower desires that a Letter of Credit be issued, amended or renewed for its account on its own behalf, or on behalf of its Restricted Subsidiaries, the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the applicable Issuing Bank) to the applicable Issuing Bank and the Administrative Agent a Letter of Credit application, amendment request or any such document as may be approved by the applicable Issuing Bank (each, a “Letter of Credit

81

Application”). Upon receipt of any Letter of Credit Application or amendment request, (i) in the case of Letters of Credit denominated in Dollars, (A) the applicable Issuing Bank will use its best efforts to process such Letter of Credit Application on the Business Day on which such Letter of Credit Application is received, provided that such Letter of Credit Application is received no later than 12:00 p.m. (New York City time) on such Business Day, or (B) otherwise, the first Business Day next succeeding receipt of such Letter of Credit Application, and (ii) in the case of Letters of Credit denominated in an Alternate Currency, (A) the applicable Issuing Bank will use its best efforts to process such Letter of Credit Application on the second Business Day after the day on which such Letter of Credit Application is received, or (B) otherwise, the fifth Business Day after the day on which such Letter of Credit Application is received. No Issuing Bank shall issue any Letters of Credit unless such Issuing Bank shall have received notice from the Administrative Agent that the conditions to such issuance have been met.

(b)                                 If the Borrower so requests in any applicable Letter of Credit Application, the applicable Issuing Bank may, in its sole and absolute discretion, agree to issue a Letter of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit such Issuing Bank to prevent any such extension at least once in each 12-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in each such 12-month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by the applicable Issuing Bank, the Borrower shall not be required to make a specific request to such Issuing Bank for any such extension. Once an Auto-Extension Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) the applicable Issuing Bank to permit the extension of such Letter of Credit at any time to an expiry date not later than the L/C Maturity Date; provided, however, that such Issuing Bank shall not permit any such extension if (i) such Issuing Bank has determined that it would not be permitted, or would have no obligation, at such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of clause (b) of Section 3.1 or otherwise), or (ii) it has received notice (which may be by telephone or in writing) on or before the day that is five Business Days before the Non-Extension Notice Date (A) from the Administrative Agent that the Majority Lenders have elected not to permit such extension or (B) from the Administrative Agent, any Lender or the Borrower that one or more of the applicable conditions specified in Section 7 are not then satisfied, and in each such case directing such Issuing Bank not to permit such extension.

(c)                                  Each Issuing Bank (other than the Administrative Agent or any of its Affiliates) shall, at least once each week, provide the Administrative Agent with a list of all Letters of Credit issued by it that are outstanding at such time; provided that, upon written request from the Administrative Agent, such Issuing Bank shall thereafter notify the Administrative Agent in writing on each Business Day of all Letters of Credit issued on the prior Business Day by such Issuing Bank; provided further that the notification requirements of this Section 3.2(c) shall not apply with respect to any Existing Letter of Credit.

(d)                                 The making of each Letter of Credit Request shall be deemed to be a representation and warranty by the Borrower that the Letter of Credit may be issued in accordance with, and will not violate the requirements of, Section 3.1(b).

82

3.3                               Letter of Credit Participations.

(a)                                 Immediately upon the issuance by an Issuing Bank of any Letter of Credit (and on the Closing Date, with respect to the Existing Letters of Credit), such Issuing Bank shall be deemed to have sold and transferred to each Lender (each such Lender, in its capacity under this Section 3.3, an “L/C Participant”), and each such L/C Participant shall be deemed irrevocably and unconditionally to have purchased and received from such Issuing Bank, without recourse or warranty, an undivided interest and participation (each an “L/C Participation”), to the extent of such L/C Participant’s Commitment Percentage, in each Letter of Credit, each substitute therefor, each drawing made thereunder and the obligations of the Borrower under this Agreement with respect thereto, and any security therefor or guaranty pertaining thereto.

(b)                                 In determining whether to pay under any Letter of Credit, the relevant Issuing Bank shall have no obligation relative to the L/C Participants other than to confirm that (i) any documents required to be delivered under such Letter of Credit have been delivered, (ii) such Issuing Bank has examined the documents with reasonable care and (iii) the documents appear to comply on their face with the requirements of such Letter of Credit. Any action taken or omitted to be taken by the relevant Issuing Bank under or in connection with any Letter of Credit issued by it, if taken or omitted in the absence of gross negligence or willful misconduct, shall not create for such Issuing Bank any resulting liability.

(c)                                  In the event that an Issuing Bank makes any payment under any Letter of Credit issued by it and the Borrower shall not have repaid such amount (calculated, in the case of Alternate Currency Letters of Credit, based on the Dollar Equivalent thereof) in full to such Issuing Bank pursuant to Section 3.4(a), such Issuing Bank shall promptly notify the Administrative Agent and each L/C Participant of such failure, and each such L/C Participant shall promptly and unconditionally pay to the Administrative Agent for the account of such Issuing Bank, the amount of such L/C Participant’s Commitment Percentage of such unreimbursed payment in Dollars and in immediately available funds; provided, however, that no L/C Participant shall be obligated to pay to the Administrative Agent for the account of such Issuing Bank its Commitment Percentage of such unreimbursed amount arising from any wrongful payment made by such Issuing Bank under any such Letter of Credit as a result of acts or omissions constituting willful misconduct or gross negligence on the part of such Issuing Bank. Each L/C Participant shall make available to the Administrative Agent for the account of the relevant Issuing Bank such L/C Participant’s Commitment Percentage of the amount of such payment no later than 1:00 p.m. (New York City time) on the first Business Day after the date notified by such Issuing Bank in immediately available funds. If and to the extent such L/C Participant shall not have so made its Commitment Percentage of the amount of such payment available to the Administrative Agent for the account of the relevant Issuing Bank, such L/C Participant agrees to pay to the Administrative Agent for the account of such Issuing Bank, forthwith on demand, such amount, together with interest thereon for each day from such date until the date such amount is paid to the Administrative Agent for the account of such Issuing Bank at a rate per annum equal to the Overnight Rate from time to time then in effect, plus any administrative, processing or similar fees customarily charged by such Issuing Bank in connection with the foregoing. The failure of any L/C Participant to make available to the Administrative Agent for the account of any Issuing Bank its Commitment Percentage of any payment under any Letter of Credit shall not relieve any

83

other L/C Participant of its obligation hereunder to make available to the Administrative Agent for the account of such Issuing Bank its Commitment Percentage of any payment under such Letter of Credit on the date required, as specified above, but no L/C Participant shall be responsible for the failure of any other L/C Participant to make available to the Administrative Agent such other L/C Participant’s Commitment Percentage of any such payment.

(d)                                 Whenever an Issuing Bank receives a payment in respect of an unpaid reimbursement obligation as to which the Administrative Agent has received for the account of such Issuing Bank any payments from the L/C Participants pursuant to clause (c) above, such Issuing Bank shall pay to the Administrative Agent and the Administrative Agent shall promptly pay to each L/C Participant that has paid its Commitment Percentage of such reimbursement obligation, in Dollars and in immediately available funds, an amount equal to such L/C Participant’s share (based upon the proportionate aggregate amount originally funded by such L/C Participant to the aggregate amount funded by all L/C Participants) of the principal amount so paid in respect of such reimbursement obligation and interest thereon accruing after the purchase of the respective L/C Participations at the Overnight Rate.

(e)                                  The obligations of the L/C Participants to make payments to the Administrative Agent for the account of an Issuing Bank with respect to Letters of Credit shall be irrevocable and not subject to counterclaim, set-off or other defense or any other qualification or exception whatsoever and shall be made in accordance with the terms and conditions of this Agreement under all circumstances, including under any of the following circumstances:

(i)                                     any lack of validity or enforceability of this Agreement or any of the other Credit Documents;

(ii)                                  the existence of any claim, set-off, defense or other right that the Borrower may have at any time against a beneficiary named in a Letter of Credit, any transferee of any Letter of Credit (or any Person for whom any such transferee may be acting), the Administrative Agent, any Issuing Bank, any Lender or other Person, whether in connection with this Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated transactions (including any underlying transaction between the Borrower and the beneficiary named in any such Letter of Credit);

(iii)                               any draft, certificate or any other document presented under any Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

(iv)                              the surrender or impairment of any security for the performance or observance of any of the terms of any of the Credit Documents; or

(v)                                 the occurrence of any Default or Event of Default;

provided, however, that no L/C Participant shall be obligated to pay to the Administrative Agent for the account of any Issuing Bank its Commitment Percentage of any unreimbursed amount arising from any wrongful payment made by such Issuing Bank under a Letter of Credit as a

84

result of acts or omissions constituting willful misconduct, bad faith or gross negligence on the part of such Issuing Bank.

3.4                               Agreement to Repay Letter of Credit Drawings.

(a)                                 The Borrower hereby agrees to reimburse the relevant Issuing Bank by making payment in Dollars or, in the case of Alternate Currency Letters of Credit, in the applicable Alternate Currency to such Issuing Bank or to the Administrative Agent for the account of such Issuing Bank (whether with its own funds or with proceeds of the Loans) in immediately available funds, for any payment or disbursement made by such Issuing Bank under any Letter of Credit issued by it (each such amount so paid until reimbursed, an “Unpaid Drawing” (calculated, in the case of Alternate Currency Letters of Credit, based on the Dollar Equivalent thereof)) (i) within one Business Day of the date of such payment or disbursement if such Issuing Bank provides notice to the Borrower of such payment or disbursement prior to 11:00 a.m. (New York City time) on such next succeeding Business Day (from the date of such payment or disbursement or (ii) if such notice is received after such time, on the next Business Day following the date of receipt of such notice (such required date for reimbursement under clause (i) or (ii), as applicable, on such Business Day (the “Reimbursement Date”)), with interest on the amount so paid or disbursed by such Issuing Bank, from and including the date of such payment or disbursement to but excluding the Reimbursement Date, at the per annum rate for each day equal to the rate described in Section 2.8(a); provided that, notwithstanding anything contained in this Agreement to the contrary, with respect to any Letter of Credit, (i) unless the Borrower shall have notified the Administrative Agent and such Issuing Bank prior to 11:00 a.m. (New York City time) on the Reimbursement Date that the Borrower intends to reimburse such Issuing Bank for the amount of such drawing with funds other than the proceeds of Loans, the Borrower shall be deemed to have given a Notice of Borrowing requesting that the Lenders make Loans (which shall be ABR Loans) on the Reimbursement Date in an amount equal to the amount at such drawing (calculated, in the case of Alternate Currency Letters of Credit, based on the Dollar Equivalent thereof), and (ii) the Administrative Agent shall promptly notify each L/C Participant of such drawing and the amount of its Loan to be made in respect thereof, and each L/C Participant shall be irrevocably obligated to make a Loan to the Borrower in the manner deemed to have been requested in the amount of its Commitment Percentage of the applicable Unpaid Drawing by 12:00 noon (New York City time) on such Reimbursement Date by making the amount of such Loan available to the Administrative Agent. Such Loans made in respect of such Unpaid Drawing on such Reimbursement Date shall be made without regard to the Minimum Borrowing Amount and without regard to the satisfaction of the conditions set forth in Section 7. The Administrative Agent shall use the proceeds of such Loans solely for purpose of reimbursing the relevant Issuing Bank for the related Unpaid Drawing. In the event that the Borrower fails to Cash Collateralize any Letter of Credit that is outstanding on the L/C Maturity Date, the full amount of the Letters of Credit Outstanding in respect of such Letter of Credit shall be deemed to be an Unpaid Drawing subject to the provisions of this Section 3.4 except that such Issuing Bank shall hold the proceeds received from the Lenders as contemplated above as cash collateral for such Letter of Credit to reimburse any Drawing under such Letter of Credit and shall use such proceeds first, to reimburse itself for any Drawings made in respect of such Letter of Credit following the L/C Maturity Date, second, to the extent such Letter of Credit expires or is returned undrawn while any such cash collateral remains, to the repayment of obligations in

85

respect of any Loans that have not paid at such time and third, to the Borrower or as otherwise directed by a court of competent jurisdiction. Nothing in this Section 3.4(a) shall affect the Borrower’s obligation to repay all outstanding Loans when due in accordance with the terms of this Agreement.

(b)                                 The obligations of the Borrower under this Section 3.4 to reimburse the relevant Issuing Bank with respect to Unpaid Drawings (including, in each case, interest thereon) shall be absolute, unconditional and irrevocable under any and all circumstances and irrespective of any set-off, counterclaim or defense to payment that the Borrower or any other Person may have or have had against such Issuing Bank, the Administrative Agent or any Lender (including in its capacity as an L/C Participant), including any defense based upon (i) the failure of any drawing under a Letter of Credit (each a “Drawing”) to conform to the terms of the Letter of Credit, (ii) any non-application or misapplication by the beneficiary of the proceeds of such Drawing, (iii) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (iv) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect or (v) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder; provided that the foregoing shall not be construed to excuse the relevant Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to special, indirect, consequential or punitive damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by such Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The Borrower agrees that any action taken or omitted to be taken by an Issuing Bank under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence or willful misconduct (as finally determined by a court of competent jurisdiction), shall be binding on the Borrower and shall not result in any liability of such Issuing Bank to the Borrower; provided that the foregoing shall not be construed to excuse such Issuing Bank from liability to the Borrower to the extent of any direct damages suffered by the Borrower that are caused by such Issuing Bank’s failure to exercise care, when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. In furtherance of the foregoing, the parties hereto agree that, with respect to documents presented which appear on their face to be in compliance with the terms of a Letter of Credit, the Issuing Bank that issued such Letter of Credit may in its sole discretion, either accept or make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit (unless the Borrower shall consent to payment thereon not withstanding such lack of strict compliance).

3.5                               Increased Costs. If, after the Closing Date, the adoption of any Change in Law shall either (a) impose, modify or make applicable any reserve, deposit, capital adequacy or similar requirement against Letters of Credit issued by any Issuing Bank, or any L/C Participant’s L/C Participation therein, or (b) impose on any Issuing Bank or any L/C Participant any other conditions, costs or expenses affecting its obligations under this Agreement in respect of

86

Letters of Credit or L/C Participations therein or any Letter of Credit or such L/C Participant’s L/C Participation therein, and the result of any of the foregoing is to increase the cost to such Issuing Bank or such L/C Participant of issuing, maintaining or participating in any Letter of Credit, or to reduce the amount of any sum received or receivable by such Issuing Bank or such L/C Participant hereunder (other than (i) Taxes indemnifiable under Section 5.4, or (ii) Excluded Taxes) in respect of Letters of Credit or L/C Participations therein, then, promptly (and in any event no later than 15 days) after receipt of written demand to the Borrower by such Issuing Bank or such L/C Participant, as the case may be (a copy of which notice shall be sent by such Issuing Bank or such L/C Participant to the Administrative Agent), the Borrower shall pay to such Issuing Bank or such L/C Participant such additional amount or amounts as will compensate such Issuing Bank or such L/C Participant for such increased cost or reduction, it being understood and agreed, however, that no Issuing Bank or L/C Participant shall be entitled to such compensation as a result of such Person’s compliance with, or pursuant to any request or directive to comply with, any such Requirement of Law as in effect on the Closing Date. A certificate submitted to the Borrower by the relevant Issuing Bank or an L/C Participant, as the case may be (a copy of which certificate shall be sent by such Issuing Bank or such L/C Participant to the Administrative Agent), setting forth in reasonable detail the basis for the determination of such additional amount or amounts necessary to compensate such Issuing Bank or such L/C Participant as aforesaid shall be conclusive and binding on the Borrower absent clearly demonstrable error.

3.6                               New or Successor Issuing Bank.

(a)                                 Any Issuing Bank may resign as an Issuing Bank upon 30 days’ prior written notice to the Administrative Agent, the Lenders and the Borrower. The Borrower may replace any Issuing Bank for any reason upon written notice to such Issuing Bank and the Administrative Agent and may add Issuing Banks at any time upon notice to the Administrative Agent. If an Issuing Bank shall resign or be replaced, or if the Borrower shall decide to add a new Issuing Bank under this Agreement, then the Borrower may appoint from among the Lenders a successor issuer of Letters of Credit or a new Issuing Bank, as the case may be, or, with the consent of the Administrative Agent (such consent not to be unreasonably withheld) and such new Issuing Bank, another successor or new issuer of Letters of Credit, whereupon such successor issuer shall succeed to the rights, powers and duties of the replaced or resigning Issuing Bank under this Agreement and the other Credit Documents, or such new issuer of Letters of Credit shall be granted the rights, powers and duties of an Issuing Bank hereunder, and the term “Issuing Bank” shall mean such successor or such new issuer of Letters of Credit effective upon such appointment. The acceptance of any appointment as an Issuing Bank hereunder whether as a successor issuer or new issuer of Letters of Credit in accordance with this Agreement, shall be evidenced by an agreement entered into by such new or successor issuer of Letters of Credit, in a form reasonably satisfactory to the Borrower and the Administrative Agent and, from and after the effective date of such agreement, such new or successor issuer of Letters of Credit shall become an “Issuing Bank” hereunder. After the resignation or replacement of an Issuing Bank hereunder, the resigning or replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement and the other Credit Documents with respect to Letters of Credit issued by it prior to such resignation or replacement, but shall not be required to issue additional Letters of Credit. In connection with any resignation or
