If, on the date such request is made, the Dollar Amount of the sum of the outstanding Revolving Advances and the Letter of Credit Exposure is equal to or less than 50% of the aggregate Revolving Commitments, then subject to the terms and conditions hereof, the applicable Foreign Swingline Lender will, not later than 2:00 p.m. (in the Applicable Time) on the borrowing date specified for such Swingline Advance, make the amount of such Swingline Advance available at the Borrower’s account with the Administrative Agent or such other accounts as may be designated by the Borrower. However, if on the date such request is made, the Dollar Amount of the sum of the outstanding Revolving Advances and the Letter of Credit Exposure is greater than 50% of the aggregate Revolving Commitments, then (A) promptly after receipt by the applicable Foreign Swingline Lender of any request for a Foreign Swingline Advance, the applicable Foreign Swingline Lender will confirm with the Administrative Agent that the Administrative Agent has also received such request and, if not, the applicable Foreign Swingline Lender will notify the Administrative Agent of the contents thereof, and (B) unless the applicable Foreign Swingline Lender has received notice in writing from the Administrative Agent (including at the request of any Lender) prior to 2:00 p.m. (in the Applicable Time) on the date of the proposed Swingline Advance directing the applicable Foreign Swingline Lender not to make such Swingline Advance as a result of the limitations set

forth in the first proviso of Section 2.1(b) above then, subject to the terms and conditions hereof, the applicable foreign Swingline Lender will, not later than 3:00 p.m. (in the Applicable Time) on the borrowing date specified for such Swingline Advance, make the amount of such Swingline Advance available at the Borrower’s account with the Administrative Agent or such other accounts as may be designated by the Borrower.

(iv) With respect to Swingline Advances denominated in Dollars, each Swingline Lender at any time in its sole and absolute discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes each Swingline Lender to so request on its behalf), that each Lender make an Adjusted Base Rate Advance in an amount equal to such Lender’s Pro Rata Share of such Swingline Advances in order to refinance such Swingline Advances. With respect to Foreign Swingline Advances, each Swingline Lender in its sole and absolute discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes each Swingline Lender to so request on its behalf), that each Lender make a Eurocurrency Rate Advance in the same Foreign Currency, in an amount equal to such Lender’s Pro Rata Share of such Swingline Advances and with Interest Period of one month. The applicable Swingline Lender shall give the Administrative Agent notice of such Mandatory Revolving Borrowing (A) by 12:00 p.m. (Houston, Texas time) on the date before the proposed Mandatory Revolving Borrowing is to be made in the case of an Adjusted Base Rate Advance and (B) by 12:00 p.m. (Houston, Texas time) on the fourth Business Day before the date of such proposed Mandatory Revolving Borrowing in the case of a Eurocurrency Rate Advance denominated in a Foreign Currency, which notice the Administrative Agent will promptly forward to each Lender. Each Lender shall make its Revolving Advance available to the Administrative Agent for the account of the applicable Swingline Lender in immediately available funds by 2:00 p.m. (Houston, Texas time) on the date requested, and the Borrower hereby irrevocably instructs the applicable Swingline Lender to apply the proceeds of such Mandatory Revolving Borrowing to the payment of the outstanding Swingline Advances.

(v) If for any reason any Swingline Advance cannot be refinanced by a Revolving Borrowing in accordance with clause (iv) above, the request for the Revolving Advances submitted by the applicable Swingline Lender as set forth therein shall be deemed to be a request by such Swingline Lender that each of the Lenders fund its risk participation in the relevant Swingline Advances and each Lender’s payment to the Administrative Agent for the account of the applicable Swingline Lender pursuant to clause (iv) above shall be deemed payment in respect of such participation.

(vi) If any Lender fails to make available to the Administrative Agent for the account of the applicable Swingline Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.1(b) by the time specified in this Section 2.1(b), such Swingline Lender shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to such Swingline Lender at a rate per annum equal to the applicable Overnight Rate from time to time in effect. A certificate of such Swingline Lender submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (vi) shall be conclusive absent manifest error.

(vii) Each Lender’s obligation to make the Revolving Advances or to purchase and fund risk participations in Swingline Advances pursuant to this Section 2.1(b) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against any

Swingline Lender, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, (C) whether or not the conditions precedent in Section 3.2 have been satisfied, (D) termination of the Revolving Commitments or acceleration of the Advances, and (E) any other occurrence, event or condition, whether or not similar to any of the foregoing. No such funding of risk participations shall relieve or otherwise impair the obligation of the Borrower to repay Swingline Advances, together with interest as provided herein.

(viii) At any time after any Lender has purchased and funded a risk participation in a Swingline Advance, if the applicable Swingline Lender receives any payment on account of such Swingline Advance, such Swingline Lender will distribute to such Lender its Pro Rata Share of such payment (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s risk participation was funded) in the same funds as those received by such Swingline Lender.

(ix) Each Swingline Lender shall be responsible for invoicing the Borrower for interest on the Swingline Advances made by such Swingline Lender. Until a Lender funds its Adjusted Base Rate Advance, Eurocurrency Rate Advance or risk participation pursuant to this Section 2.1(b) to refinance such Lender’s Pro Rata Share of any Swingline Advance, interest in respect of such Pro Rata Share shall be solely for the account of the applicable Swingline Lender.

(x) The Borrower shall make all payments of principal and interest in respect of any Swingline Advances directly to the applicable Swingline Lender.

(xi) For purposes of calculating outstandings under this Agreement (a) on each March 31, June 30, September 30 and December 31, commencing September 30, 2012, and (b) from time to time as the Administrative Agent may request, each Swingline Lender shall provide the Administrative Agent with a daily log, in form and detail reasonably acceptable to the Administrative Agent, setting forth the outstanding Dollar Amount of the Swingline Advances made by such Swingline Lender using the Exchange Rate as most recently determined by the Administrative Agent.

(a) Notice. Each Revolving Borrowing shall be made pursuant to a Notice of Borrowing and given:

(i) by the Borrower to the Administrative Agent not later than 12:00 p.m. (Houston, Texas time) on the fourth Business Day before the date of the proposed Borrowing in the case of a Eurocurrency Rate Advance denominated in a Foreign Currency,

(ii) by the Borrower to the Administrative Agent not later than 12:00 p.m. (Houston, Texas time) on the third Business Day before the date of the proposed Borrowing in the case of a Eurocurrency Rate Advance denominated in Dollars, and

The Administrative Agent shall give each Lender prompt notice on the day of receipt of timely Notice of Borrowing of such proposed Borrowing by facsimile. Each Notice of Borrowing shall be by telephone or facsimile, and if by telephone, confirmed promptly in writing (which confirmation may be provided by facsimile or with a “PDF” file delivered in an e-mail with a return acknowledgment requested), specifying the (i) requested date of such Borrowing (which shall be a Business Day), (ii) requested Type of Advances comprising such Borrowing, (iii) aggregate amount of such Borrowing, (iv) if such Borrowing is to be comprised of Eurocurrency Rate Advances, the Interest Period for each such Advance, and (v) the Designated Currency of such Borrowing. In the case of a proposed Borrowing comprised of Eurocurrency Rate Advances, the Administrative Agent shall promptly notify each Lender of the applicable interest rate under Section 2.6(b). Each Lender shall, before 3:00 p.m. (Houston, Texas time) on the date of the proposed Borrowing, make available for the account of its Lending Office to the Administrative Agent at its address referred to in Section 9.2, or such other location as the Administrative Agent may specify by notice to the Lenders, in same day funds, such Lender’s Pro Rata Share of such Borrowing. Promptly upon the Administrative Agent’s receipt of such funds (but in any event not later than 4:00 p.m. (Houston, Texas time) on the date of the proposed Borrowing) and provided that the applicable conditions set forth in Article III have been satisfied, the Administrative Agent will make such funds available to the Borrower at its account with the Administrative Agent.

(b) Conversions and Continuations. In order to elect to Convert or continue Advances comprising part of the same Revolving Borrowing under this Section, the Borrower shall deliver an irrevocable Notice of Conversion or Continuation to the Administrative Agent at the Administrative Agent’s office no later than 12:00 p.m. (Houston, Texas time) (i) at least one Business Day in advance of the proposed conversion date in the case of a Conversion of such Advances to Adjusted Base Rate Advances, (ii) at least three Business Days in advance of the proposed Conversion or continuation date in the case of a Conversion to, or a continuation of, Eurocurrency Rate Advances denominated in Dollars; and (iii) at least four Business Days in advance of the proposed Conversion or continuation date in the case of a Conversion to, or a continuation of, Eurocurrency Rate Advances denominated in Foreign Currencies. Each such Notice of Conversion or Continuation shall be by telephone or facsimile, and if by telephone, confirmed promptly in writing (which confirmation may be provided by facsimile or with a “PDF” file delivered in an e-mail with a return acknowledgment requested), specifying (A) the requested Conversion or continuation date (which shall be a Business Day), (B) the Borrowing amount and Type of the Advances to be Converted or continued, (C) whether a Conversion or continuation is requested, and if a Conversion, into what Type of Advances, and (D) in the case of a Conversion to, or a continuation of, Eurocurrency Rate Advances, the requested Interest Period. Promptly after receipt of a Notice of Conversion or Continuation under this paragraph, the Administrative Agent shall provide each Lender with a copy thereof and, in the case of a Conversion to or a continuation of Eurocurrency Rate Advances, notify each Lender of the applicable interest rate under Section 2.6(b). For purposes other than the conditions set forth in Section 3.2, the portion of Revolving Advances comprising part of the same Revolving Borrowing that are Converted to Revolving Advances of another Type shall constitute a new Revolving Borrowing.

(i) each Borrowing (other than a Borrowing of Swingline Advances) shall (A) in the case of Eurocurrency Rate Advances, be in an aggregate amount not less than $3,000,000 and greater multiples of $1,000,000 in excess thereof, (B) in the case of Adjusted Base Rate Advances, be in an aggregate amount not less than $500,000 and greater multiples of $100,000 in excess thereof, and (C) consist of Advances of the same Type made on the same day by the Lenders according to their Pro Rata Share;

(ii) at no time shall there be more than eight Interest Periods applicable to outstanding Eurocurrency Rate Advances;

(iii) no single Borrowing consisting of Eurocurrency Rate Advances may include Advances in different currencies;

(iv) the Borrower may not select Eurocurrency Rate Advances for any Borrowing to be made, Converted or continued if (A) the aggregate Dollar Amount of such Borrowing is less than $3,000,000 or (B) a Default or Event of Default has occurred and is continuing;

(v)(A) if any Lender shall, at any time prior to the making of any requested Borrowing comprised of Eurocurrency Rate Advances, notify the Administrative Agent that the introduction of or any change in or in the interpretation of any Legal Requirement makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful, for such Lender or its Lending Office to perform its obligations under this Agreement to make Eurocurrency Rate Advances or to fund or maintain Eurocurrency Rate Advances, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or take deposits of, Dollars or any Foreign Currency in the applicable interbank market, then (1) if the requested Borrowing was of Revolving Advances denominated in Dollars, such Lender’s Pro Rata Share of such Borrowing shall be made as an Adjusted Base Rate Advance of such Lender, (2) in any event, such Adjusted Base Rate Advance shall be considered part of the same Borrowing and interest on such Adjusted Base Rate Advance shall be due and payable at the same time that interest on the Eurocurrency Rate Advances comprising the remainder of such Borrowing shall be due and payable, and (3) any obligation of such Lender to make, continue, or Convert to, Eurocurrency Rate Advances in the affected currency or currencies, including in connection with such requested Borrowing, shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist; and (B) such Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to designate a different Lending Office if the making of such designation would avoid the effect of this paragraph and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender;

(vi) if the Administrative Agent is unable to determine the Eurocurrency Rate for Eurocurrency Rate Advances comprising any requested Revolving Borrowing, the right of the Borrower to select Eurocurrency Rate Advances in the affected currency or currencies for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, and upon receipt by the Borrower of the notice of such suspension, the Borrower may revoke the pending request or, failing that, each Revolving Advance comprising such Borrowing shall be made as an Adjusted Base Rate Advance in the Dollar Amount of the originally requested Advance;

(vii) if the Majority Lenders shall, at least one Business Day before the date of any requested Borrowing, notify the Administrative Agent that (A) the Eurocurrency Rate for Eurocurrency Rate Advances comprising such Borrowing will not adequately reflect the cost to such Lenders of making or funding their respective Eurocurrency Rate Advances, or (B) deposits are not being offered to banks in the applicable offshore interbank market for such currency for the applicable amount and Interest Period of such Eurocurrency Rate Advance, the right of the Borrower to select Eurocurrency Rate Advances in the affected currency or currencies for such Borrowing or for any subsequent Revolving Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, and upon receipt by the Borrower of the notice of such suspension, the Borrower may revoke the pending request or, failing that, each Advance comprising such Borrowing shall be made as an Adjusted Base Rate Advance in the Dollar Amount of the originally requested Advance;

(viii) if any Lender shall, at any time prior to the making of any requested Borrowing comprised of Eurocurrency Rate Advances denominated in a Foreign Currency, notify the Administrative Agent that, as a result of internal banking policy limitations on fundings in such Foreign Currency, such Lender can not fund all or any portion of its Pro Rata Share of such Borrowing, then (A) such portion shall be made as an Adjusted Base Rate Advance of such Lender, and (B) in any event, such Adjusted Base Rate Advance shall be considered part of the same Borrowing and interest on such Adjusted Base Rate Advance shall be due and payable at the same time that interest on the Eurocurrency Rate Advances comprising the remainder of such Borrowing shall be due and payable;

(ix) if the Borrower shall fail to select the duration or continuation of any Interest Period for any Eurocurrency Rate Advance in accordance with the provisions contained in the definition of “Interest Period” in Section 1.1 and paragraph (a) or (b) above, the Administrative Agent will forthwith so notify the Borrower and the Lenders and (A) if denominated in Dollars, such affected Advances will be made available to the Borrower on the date of such Borrowing as Adjusted Base Rate Advances or, if such affected Advances are existing Advances, will be Converted into Adjusted Base Rate Advances or at the end of Interest Period then in effect, and (B) if denominated in a Foreign Currency, the Borrower shall be deemed to have specified an Interest Period of one month for such affected Advances or, if such affected Advances are existing Advances, such affected Advances will be continued as a Eurocurrency Rate Advance in the original Designated Currency with an Interest Period of one month;

(x) if the Borrower shall fail to specify a currency for any Eurocurrency Rate Advances, then the Eurocurrency Rate Advances as requested shall be made in Dollars;

(xi) Revolving Advances may only be Converted or continued as Revolving Advances;

(xiii) no Revolving Advance may be Converted or continued as a Revolving Advance in a different currency, but instead must be prepaid in the original Designated Currency of such Revolving Advance and reborrowed in such new Designated Currency.

(d) Notices Irrevocable. Each Notice of Borrowing and Notice of Conversion or Continuation shall be irrevocable and binding on the Borrower.

(e) Administrative Agent Reliance. Unless the Administrative Agent shall have received notice from a Lender before the date of any Revolving Borrowing or Mandatory Revolving Borrowing that such Lender will not make available to the Administrative Agent such Lender’s Pro Rata Share of such Borrowing, the Administrative Agent may assume that such Lender has made its Pro Rata Share of such Borrowing available to the Administrative Agent on the date of such Borrowing in accordance with paragraph (a) of this Section 2.2 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made its Pro Rata Share of such Borrowing available to the Administrative Agent, such Lender and the Borrower severally agree to immediately repay to the

Administrative Agent on demand such corresponding amount, together with interest on such amount, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable on such day to Advances comprising such Borrowing and (ii) in the case of such Lender, the Overnight Rate for such day. If such Lender shall repay to the Administrative Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement even though not made on the same day as the other Advances comprising such Borrowing.

(f) Lender Obligations Several. The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, to make its Advance on the date of such Borrowing. No Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing.

(i) The Advances made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by Administrative Agent and the Lenders shall be conclusive absent manifest error of the amount of the Advances made by such Lenders to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender to the Borrower made through the Administrative Agent, the Borrower shall execute and deliver to such Lender (through the Administrative Agent) the applicable Note or Notes which shall evidence such Lender’s Advances to the Borrower in addition to such accounts or records. Each Lender may attach schedules to such Notes and endorse thereon the date, Type (if applicable), amount, currency and maturity of its Advances and payments with respect thereto.

(ii) In addition to the accounts and records referred to in subsection (i) above, each Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit and Swingline Advances. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

(a) Commitment Fees. Subject to Section 2.20(a)(iii), the Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee (the “Commitment Fee”) equal to the Applicable Margin for Commitment Fees times the actual daily amount by which such Lender’s Revolving Commitment exceeds the sum of such Lender’s Revolving Advances plus such Lender’s Pro Rata Share of the Letter of Credit Exposure, for the period from the Closing Date until the Maturity Date (including at any time during which one or more of the conditions in Article III is not met). The Commitment Fees shall be due and payable quarterly in arrears on the tenth (10^th) day after the end of each March, June, September and December, commencing September 30, 2012, and on the Maturity Date. For the avoidance of doubt, Swingline Advances shall not reduce the amount of unused Revolving Commitment solely for purposes of calculating the Commitment Fee under this Section 2.3(a).

(b) Letter of Credit Fees. The Borrower agrees to pay to the Administrative Agent for the pro rata benefit of the Lenders letter of credit fees in respect of all Letters of Credit outstanding at a rate per annum equal to the Applicable Margin for Eurocurrency Rate Advances calculated on the maximum amount available from time to time to be drawn under such outstanding Letters of Credit. All such letter of credit fees shall be (i) calculated quarterly in arrears for the period ending on the last day of each March, June, September and December, commencing September 30, 2012 and due and payable on the immediately following 10^th Business Day, and (ii) calculated in arrears and ending on, and due and payable on, the Maturity Date. In addition, the Borrower agrees to pay to each Issuing Lender for its own account fronting fees in respect of all Letters of Credit outstanding and issued by such Issuing Lender equal to the greater of (A) one-eighth percent (1/8%) per annum of the maximum amount available from time to time to be drawn under such outstanding Letters of Credit and (B) $500, payable at issuance and on the earlier of each annual anniversary thereafter or the Maturity Date. The Borrower shall also pay to each Issuing Lender for its own account such documentary, processing and other charges in connection with the issuance, amendment, transfer, modification of and draws under Letters of Credit assessed or incurred by such Issuing Lender from time to time. For purposes of calculating the letter of credit fees, fronting fees and other fees under this Section 2.3(b), the face amount of each Letter of Credit made in a Foreign Currency shall be at any time the Dollar Amount of such Letter of Credit as determined on the most recent Computation Date with respect to such Letter of Credit.

(c) Fee Letters. The Borrower agrees to pay when due the fees set forth in the Fee Letters, in each case, pursuant to the terms thereof.

Section 2.4 Reduction of Revolving Commitments. The Borrower shall have the right, upon at least three Business Days’ irrevocable notice to the Administrative Agent and the Lenders, to terminate in whole or reduce ratably in part the unused portion of the Revolving Commitments; provided that, each partial reduction shall be in the aggregate amount of $3,000,000 or an integral multiple of $1,000,000 in excess thereof. Any reduction or termination of the Revolving Commitments pursuant to this Section 2.4 shall be permanent, with no obligation of the Lenders to reinstate such Revolving Commitments and the Commitment Fees provided for in Section 2.3(a) shall thereafter be computed on the basis of the Revolving Commitments, as so reduced.

(a) Revolving Advances. The Borrower shall repay the outstanding principal amount of each Revolving Advance on the Maturity Date and, for each Mandatory Revolving Borrowing made on or after the Maturity Date, on demand, and in any event, in the Designated Currency in which each such Advance was funded.

(b) Swingline Advances. The Borrower shall repay the outstanding principal amount of each Swingline Advance on the earlier of (i) the Swingline Due Date immediately following the date such Swingline Advance is made by the applicable Swingline Lender and (ii) the Maturity Date.

Section 2.6 Interest. The Borrower shall pay interest on the unpaid principal amount of each Advance from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum:

(a) Adjusted Base Rate Advances. If such Advance is an Adjusted Base Rate Advance, a rate per annum equal at all times to the lesser of (i) the Adjusted Base Rate in effect from time

to time plus the Applicable Margin for Adjusted Base Rate Advances and (ii) the Maximum Rate, payable in arrears on the last Business Day of each calendar quarter, commencing with the calendar quarter ending September 30, 2012, and on the date such Adjusted Base Rate Advance shall be paid in full, provided that if any payment of principal on any Advance is not made when due, such Advances shall bear interest from the date such payment was due until such Advances are paid in full, payable on demand, at a rate per annum equal at all times to the lesser of (A) the rate required to be paid on such Advance immediately prior to the date on which such amount becomes due plus two percent (2%) and (B) the Maximum Rate.

(b) Eurocurrency Rate Advances. If such Advance is a Eurocurrency Rate Advance, during the Interest Period for such Advance, a rate per annum equal at all times to the lesser of (i) the Eurocurrency Rate for such Interest Period plus the Applicable Margin for Eurocurrency Rate Advances plus (in the case of a Eurocurrency Rate Advance of any Lender which is lent from a Lending Office in the United Kingdom or a Participating Member State) the Mandatory Cost Rate and (ii) the Maximum Rate, payable in arrears on the last day of such Interest Period (provided that for Eurocurrency Rate Advance with six month Interest Periods, accrued but unpaid interest shall also be due on the day three months from the first day of such Interest Period), and on the date such Eurocurrency Rate Advance shall be paid in full; provided that if any payment of principal on any Advance is not made when due, such Advances shall bear interest from the date such payment was due until such Advances are paid in full, payable on demand, at a rate per annum equal at all times to the lesser of (A) the greater of (1) the Adjusted Base Rate in effect from time to time plus the Applicable Margin for Adjusted Base Rate Advances plus two percent (2%) and (2) the rate required to be paid on such Advance immediately prior to the date on which such amount became due (including the Applicable Margin and any Mandatory Cost Rate) plus two percent (2%) and (B) the Maximum Rate.

(c) Swingline Advances. If such Advance is a Swingline Advance, a rate per annum equal at all times to the lesser of (i) the Swingline Rate for such Swingline Advance and (ii) the Maximum Rate, payable quarterly in arrears on the last Business Day of each calendar quarter, commencing with the calendar quarter ending September 30, 2012, and on the Maturity Date; provided that if any payment of principal on any Advance is not made when due, such Advances shall bear interest from the date such payment was due until such Advances are paid in full, at a rate per annum equal at all times to the lesser of (A) the rate required to be paid on such Advance immediately prior to the date on which such amount becomes due plus two percent (2%) and (B) the Maximum Rate.

(d) Usury Recapture. As to each Lender, in the event the rate of interest chargeable under this Agreement or the Notes at any time is greater than the Maximum Rate, the unpaid principal amount of Obligations owing to such Lender shall bear interest at the Maximum Rate until the total amount of interest paid or accrued on such Obligations equals the amount of interest which would have been paid or accrued on such Obligations if the stated rates of interest set forth in this Agreement had at all times been in effect. In the event, upon payment in full of such Obligations, the total amount of interest paid or accrued under the terms of this Agreement and the Notes as to any Lender is less than the total amount of interest which would have been paid or accrued if the rates of interest set forth in this Agreement had, at all times, been in effect, then the Borrower shall, to the extent permitted by applicable Legal Requirements, pay the Administrative Agent for the account of such Lenders an amount equal to the difference between (i) the lesser of (A) the amount of interest which would have been charged on Obligations owing to such Lender if the Maximum Rate had, at all times, been in effect and (B) the amount of interest which would have accrued on such Obligations if the rates of interest set forth in this Agreement had at all times been in effect and (ii) the amount of interest actually paid or accrued under this Agreement on such Obligations. In the event any Lender ever receives, collects or applies as interest any sum in excess of the Maximum Rate, such excess amount shall, to the extent permitted by law, be applied to the reduction of the principal balance of the Obligations owing to it, and if no such principal is then outstanding, such excess or part thereof remaining shall be paid to the Borrower.

(e) Other Amounts Overdue. If any amount payable under this Agreement other than the Advances is not paid when due and payable, including accrued interest and fees, then such overdue amount shall accrue interest hereon due and payable on demand (i) if such amount is in Dollars, at a rate per annum equal to the lesser of (A) Adjusted Base Rate plus the Applicable Margin for Adjusted Base Rate Advances plus two percent (2%) and (B) the Maximum Rate, from the date such amount became due until the date such amount is paid in full, and (ii) if such amount is in a Foreign Currency, the lesser of (A) the greater of (1) the Adjusted Base Rate in effect from time to time plus the Applicable Margin for Adjusted Base Rate Advances plus two percent (2%) and (2) the overnight Eurocurrency Rate plus the Applicable Margin for Eurocurrency Rate Advances and any Mandatory Cost Rate for Eurocurrency Rate Advances plus two percent (2%) and (B) the Maximum Rate.

(a) Right to Prepay. The Borrower shall have no right to prepay any principal amount of any Advance except as provided in this Section 2.7.

(b) Optional Prepayments. The Borrower may elect to prepay any of the Advances, after giving notice thereof to the Administrative Agent and the Lenders by 12:00 p.m. (Houston, Texas) for Advances denominated in Dollars and by 12:00 p.m. in the Applicable Time for Revolving Advances denominated in Foreign Currencies and Swingline Advances made by Foreign Swingline Lenders (i) on the day of prepayment of any Swingline Advance, (ii) at least three Business Days’ prior to the day of prepayment of any Eurocurrency Rate Advances and (iii) the day prior to the prepayment of any Adjusted Base Rate Advance. Such notice shall be by telephone or facsimile, and if by telephone, confirmed promptly in writing, and must state the proposed date and aggregate principal amount of such prepayment, whether such prepayment should be applied to reduce outstanding Revolving Advances or Swingline Advances, and if applicable, the relevant Interest Period for the Advances to be prepaid. If any such notice is given, the Borrower shall prepay Advances comprising part of the same Borrowing in whole or ratably in part in an aggregate principal amount equal to the amount specified in such notice, and shall also pay accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date; provided, however, that (i) each partial prepayment of Eurocurrency Rate Advances shall be in an aggregate principal amount of not less than $3,000,000 and in integral multiples of $1,000,000 in excess thereof, (ii) each partial prepayment of Adjusted Base Rate Advances shall be in an aggregate principal amount of not less than $500,000 and in integral multiples of $100,000 in excess thereof, (iii) each partial prepayment of Swingline Advances shall be in an aggregate principal amount of not less than $500,000, and (iv) any prepayment of an Advance shall be made in the Designated Currency in which such Advance was funded. Each prepayment pursuant to this Section 2.7(b) shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date.

(c) Ratable Payments. Each payment of any Advance pursuant to this Section 2.7 or any other provision of this Agreement shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part.

(d) Effect of Notice. All notices given pursuant to this Section 2.7 shall be irrevocable and binding upon the Borrower.

Section 2.8 Breakage Costs. If (a) any payment of principal of any Eurocurrency Rate Advance is made other than on the last day of the Interest Period for such Advance as a result of any payment hereunder or the acceleration of the maturity of the Obligations pursuant to Article VIII or otherwise; (b) the Borrower fails to borrow, Convert, continue, repay or prepay any Eurocurrency Rate Advance on the date specified in any notice delivered pursuant hereto (other than default by a Lender), (c) the Borrower fails to make a principal or interest payment with respect to any Eurocurrency Rate Advance on the date such payment is due and payable, the Borrower shall, within 10 days of any written demand sent by any Lender to the Borrower (with a copy to the Administrative Agent), pay to the Administrative Agent for the account of such Lender any amounts (without duplication of any other amounts payable in respect of breakage costs) required to compensate such Lender for any additional losses, out-of-pocket costs or expenses which it may reasonably incur as a result of such payment or nonpayment, including any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance.

(i) 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 or participated in by, any Lender (other than any change by way of imposition or increase of reserve requirements included in the calculation of the Eurocurrency Rate but including any change or introduction which would result in the failure of the Mandatory Cost Rate, as calculated hereunder, to represent the cost to any Lender of complying with the requirements of the Bank of England and/or the Financial Services Authority or the European Central Bank in relation to its making, funding or maintaining Eurocurrency Rate Advances) or any Issuing Lender;

(ii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii) impose on any Lender or any Issuing Lender or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Advances made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, converting to, continuing or maintaining any Advance or of maintaining its obligation to make any such Advance, or to increase the cost to such Lender, such Issuing Lender or such other Recipient of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender, Issuing Lender or other Recipient hereunder (whether of principal, interest or any other amount) then, upon request of such Lender, Issuing Lender or other Recipient, the Borrower will pay to such Lender, Issuing Lender or other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender, Issuing Lender or other Recipient, as the case may be, for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender or Issuing Lender determines that any Change in Law affecting such Lender or Issuing Lender or any lending office of such Lender or such Lender’s or Issuing Lender’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender’s or Issuing Lender’s capital or on the capital of such Lender’s or Issuing Lender’s holding company, if any, as a consequence of this Agreement, the Revolving Commitments of such Lender or the Advances made by, or participations in Letters of Credit or Swingline Advances held by, such Lender, or the Letters of Credit issued by any Issuing Lender, to a level below that which such Lender or Issuing Lender or such Lender’s or Issuing Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or Issuing Lender’s policies and the policies of such Lender’s or Issuing Lender’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender or Issuing Lender or such Lender’s or Issuing Lender’s holding company for any such reduction suffered.

(c) Certificates for Reimbursement. A certificate of a Lender or Issuing Lender setting forth the amount or amounts necessary to compensate such Lender or Issuing Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section and delivered to the Borrower, shall be conclusive absent manifest error. The Borrower shall pay such Lender or Issuing Lender, as the case may be, the amount shown as due on any such certificate within 30 days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender or Issuing Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or Issuing Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or Issuing Lender pursuant to this Section for any increased costs incurred or reductions suffered more than 180 days prior to the date that such Lender or Issuing Lender, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions, and of such Lender’s or Issuing Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180 day period referred to above shall be extended to include the period of retroactive effect thereof).

(a) Payment Procedures. Except if otherwise set forth herein, the Borrower shall make each payment under this Agreement not later than 1:00 p.m. (Houston, Texas time) for payments due in Dollars and not later than 1:00 p.m. in the Applicable Time for payments due in Foreign Currencies (and payments due to Foreign Swingline Lenders related to Foreign Swingline Advances), on the day when due in the Designated Currency as to outstanding Advances and Reimbursement Obligations, and in Dollars as to all other amounts, to the Administrative Agent at its Lending Office (or such other location as the Administrative Agent shall designate in writing to the Borrower) in same day funds. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal, interest or fees ratably (other than amounts payable solely to the Administrative Agent, the Issuing Lenders, or a specific Lender pursuant to Section 2.1(b), 2.3(b), 2.3(c), 2.6(d), 2.6(e), 2.8, 2.9, 2.11, 2.12, 2.13(d), 9.4 or 9.7 but after taking into account payments effected pursuant to Section 7.6) to the Lenders in accordance with each Lender’s Pro Rata Share for the account of their respective Lending Offices, and like funds relating to the payment of any other amount payable to any Lender or any Issuing Lender to such Lender or such Issuing Lender for the account of its Lending Office, in each case to be applied in accordance with the terms of this Agreement.

(b) Computations. All computations of interest based on the Prime Rate, interest on Swingline Advances and interest on Eurocurrency Rate Advances denominated in Pounds Sterling shall be made by the Administrative Agent (or with respect to each Swingline Advance, by the applicable

Swingline Lender) on the basis of a year of 365 or 366 days, as the case may be. All computations of fees and interest based on the Eurocurrency Rate (other than as set forth in the immediately preceding sentence), Overnight Rate and the Federal Funds Rate shall be made by the Administrative Agent on the basis of a year of 360 days. In any case, such computations shall be made for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent (or with respect to each Swingline Advance, by the applicable Swingline Lender) of an interest rate shall be conclusive and binding for all purposes, absent manifest error.

(c) Non-Business Day Payments. Whenever any payment shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided, however, that if such extension would cause payment of interest on or principal of Eurocurrency Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

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

(e) Application of Payments. Whenever any payment received by the Administrative Agent under this Agreement is insufficient to pay in full all amounts then due and payable under this Agreement and Notes, such payment shall be distributed and applied by the Administrative Agent and the Lenders in the following order: first, to the payment of fees and expenses due and payable to the Administrative Agent under and in connection with this Agreement or any other Credit Document; second, to the payment of all amounts due and payable under Section 2.11(c), ratably among the Lenders in accordance with the aggregate amount of such payments owed to each such Lender; third, to the payment of fees due and payable pursuant to Section 2.3(b), ratably among the Issuing Lenders in accordance with the aggregate amount of such payments owed to each such Issuing Lender; fourth, to the payment of all other fees due and payable under Section 2.3 ratably among the Lenders in accordance with their applicable Revolving Commitments; and fifth, to the payment of the interest accrued on and the principal amount of all of the Advances, and the interest accrued on and the principal amount of all Reimbursement Obligations, regardless of whether any such amount is then due and payable, ratably among the Lenders in accordance with the aggregate accrued interest plus the aggregate principal amount owed to such Lender.

(a) Defined Terms. For purposes of this Section 2.11, the term “Lender” includes any Issuing Lender and the term “applicable law” includes FATCA

(b) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower under any Credit Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good

faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(c) Payment of Other Taxes by the Borrower. The Borrower shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes.

(d) Indemnification by the Borrower. The Borrower shall indemnify each Recipient, within 30 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e) Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within 30 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 9.6(e) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Credit Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Credit Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (e).

(f) Evidence of Payments. As soon as practicable after any payment of Taxes by the Borrower to a Governmental Authority pursuant to this Section 2.11, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Credit Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments

to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.11(g)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(A) any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable;

(1) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Credit Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Credit Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit G-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form W-8BEN; or

(4) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-2 or Exhibit G-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a

partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-4 on behalf of each such direct and indirect partner;

(C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and

(D) if a payment made to a Lender under any Credit Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so.

(h) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.11 (including by the payment of additional amounts pursuant to this Section 2.11), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(i) Survival. Each party’s obligations under this Section 2.11 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Revolving Commitments and the repayment, satisfaction or discharge of all obligations under any Credit Document.

Section 2.12 Illegality. If any Lender shall notify the Administrative Agent and the Borrower that the introduction of or any change in or in the interpretation of any Legal Requirement makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful for such Lender or its Lending Office to perform its obligations under this Agreement to maintain any Eurocurrency Rate Advances of such Lender then outstanding hereunder or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or take deposits of, Dollars or any Foreign Currency in the applicable interbank market, then, notwithstanding anything herein to the contrary, the Borrower shall, if demanded by such Lender in its notice, no later than 12:00 p.m. (Houston, Texas time), (a) if not prohibited by any Legal Requirement to maintain such Eurocurrency Rate Advances for the duration of the Interest Period, on the last day of the Interest Period for each outstanding Eurocurrency Rate Advance of such Lender or (b) if prohibited by any Legal Requirement to maintain such Eurocurrency Rate Advances for the duration of the Interest Period, on the second Business Day following its receipt of such notice from such Lender, then (i) with respect to Revolving Advances denominated in a Foreign Currency, prepay such Eurocurrency Rate Advances of such Lender then outstanding and which are denominated in such affected currency or currencies together with all accrued interest on the amount so prepaid, and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date, and (ii) with respect to Revolving Advances denominated in Dollars, Convert all such Eurocurrency Rate Advances of such Lender then outstanding to Adjusted Base Rate Advances and pay accrued interest on the principal amount Converted to the date of such Conversion and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such Conversion being made on such date. Each Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to designate a different Lending Office if the making of such designation would avoid the effect of this paragraph and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

(a) Issuance of Letters of Credit. Each Issuing Lender, the Lenders and the Borrower agree that effective as of the Closing Date, the Existing Letters of Credit shall be deemed to have been issued and maintained under, and to be governed by the terms and conditions of, this Agreement as Letters of Credit. From time to time from the date of this Agreement until ten days before the Maturity Date, at the written request of the Borrower given to the applicable Issuing Lender and to the Administrative Agent not later than (i) 12:00 p.m. (Houston, Texas time) on the third Business Day before the date of the proposed issuance, amendment, or extension of a Letter of Credit denominated in a Foreign Currency and (ii) 12:00 p.m. (Houston, Texas time) on the second Business Day (or such later time and date as may be agreed to among the Borrower, the applicable Issuing Lender and the Administrative Agent) before the date of the proposed issuance, amendment, or extension of a Letter of Credit denominated in Dollars, the requested Issuing Lender shall, on any Business Day and on the terms and conditions hereinafter set forth (and, if applicable, subject to the terms of the applicable Letter of Credit), issue, increase, decrease, amend, or extend the expiration date of, Letters of Credit for the account of the Borrower (for its own benefit or for the benefit of any of its Subsidiaries). Promptly after receipt by the applicable Issuing Lender of such request, the applicable Issuing Lender will confirm with the Administrative Agent that the Administrative Agent has also received such request and, if not, the

applicable Issuing Lender will notify the Administrative Agent of the contents thereof. With respect to any issuance of or increase to a Letter of Credit, unless the applicable Issuing Lender has received notice in writing from the Administrative Agent (including at the request of any Lender) at least one Business Day prior to the requested date of the proposed issuance or increase, directing the applicable Issuing Lender not to issue or increase such Letter of Credit as a result of the limitations set forth clause 2.13(b)(i) below then, subject to the terms and conditions hereof, the applicable Issuing Lender will issue or increase such Letter of Credit as requested by the Borrower. Letters of Credit shall be denominated in any Agreed Currency.

(b) Limitations. No Letter of Credit will be issued (or deemed issued as to the Existing Letters of Credit), increased, or extended (i) if such issuance, increase, or extension would cause the sum of the Letter of Credit Exposure plus the aggregate Dollar Amount of all outstanding Revolving Advances and Swingline Advances at such time to exceed the aggregate Revolving Commitments; (ii) unless such Letter of Credit has an Expiration Date not later than the earlier of (A) sixty months after the date of issuance thereof and (B) twenty-four months after the Maturity Date; (iii) unless such Letter of Credit (or, if applicable, the amendment to a Letter of Credit) is in form and substance acceptable to the applicable Issuing Lender in its sole discretion; (iv) unless the Borrower has delivered to the applicable Issuing Lender a completed and executed letter of credit application on such Issuing Lender’s standard form, which shall contain terms no more restrictive than the terms of this Agreement; (v) unless such Letter of Credit is governed by the Uniform Customs and Practice for Documentary Credits (2007 Revision), International Chamber of Commerce Publication No. 600 (“UCP”), the International Standby Practices (ISP 98), International Chamber of Commerce Publication No. 590 (“ISP”) or any successor to the UCP or ISP and, to the extent not inconsistent therewith, the New York Uniform Commercial Code, as in effect from time to time; or (vi) if any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain an Issuing Lender from issuing or providing such Letter of Credit, or any Legal Requirements applicable to such Issuing Lender shall prohibit the issuance or provision of such type of Letter of Credit generally or such Letter of Credit in particular or shall impose upon such Issuing Lender with respect to such Letter of Credit any restriction, reserve or capital requirement (for which such Issuing Lender is not otherwise compensated hereunder) not in effect on the date hereof or shall impose upon such Issuing Lender any unreimbursable loss, cost or expense which was not applicable on the date hereof and which such Issuing Lender in good faith deems material. If the terms of any letter of credit application referred to in the foregoing clause (iv) conflicts with the terms of this Agreement, the terms of this Agreement shall control.

(c) Participations. With respect to each Letter of Credit described on Schedule 1.1(c) which is outstanding on the Closing Date, each Lender is deemed to have purchased a participation in the related Letter of Credit Exposure equal to such Lender’s Pro Rata Share of such Letter of Credit Exposure on the Closing Date. On the date of the issuance or increase of any Letter of Credit on or after the Closing Date, each Issuing Lender shall be deemed to have sold to each other Lender and each other Lender shall have been deemed to have purchased from such Issuing Lender a participation in the Letter of Credit Exposure related to the Letters of Credit issued by such Issuing Lender equal to such Lender’s Pro Rata Share at such date and such sale and purchase shall otherwise be in accordance with the terms of this Agreement. Each Issuing Lender shall promptly deliver to the Administrative Agent by telex, telephone, or facsimile (or by e-mail with a return receipt requested) which the Administrative Agent will promptly deliver to each such participant Lender, a notice of each Letter of Credit of such Issuing Lender issued, increased or decreased, and the Administrative Agent shall also notify each Lender of the actual amount of such Lender’s participation in such Letter of Credit. Each Lender’s obligation to purchase participating interests pursuant to this Section, to make a Mandatory Revolving Borrowing as set forth in clause (d) below, to reimburse such Issuing Lender for such Lender’s Pro Rata Share of any payment under a Letter of Credit by such Issuing Lender not reimbursed in full by the Borrower, and to fund its participation interests in Letters of Credit as set forth below, shall be absolute and unconditional and shall

not be affected by any circumstance, including (i) any of the circumstances described in paragraph (f) or (e) below, (ii) the occurrence and continuance of a Default, (iii) an adverse change in the financial condition of the Borrower, (iv) any deposit of cash or other securities as collateral or the provision of any other support for the Borrower’s reimbursement obligations related thereto, (v) any termination of this Agreement other than a termination in writing agreed to by each Issuing Lender which expressly provides for a termination of the Lenders’ reimbursement obligations owing to the Issuing Lenders hereunder, and (vi) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing; provided that, a Lender may have a claim against an Issuing Lender for any such circumstance, happening or event constituting or arising from gross negligence or willful misconduct on the part of the such Issuing Lender.

(d) Reimbursement. Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the applicable Issuing Lender shall notify the Borrower and the Administrative Agent thereof (which the Administrative Agent will promptly forward to the Lenders). No later than 11:00 a.m. on the date of any payment to be made by such Issuing Lender under a Letter of Credit, the Borrower agrees to pay to such Issuing Lender an amount equal to any amount paid or to be paid by such Issuing Lender on such date under or in respect of such Letter of Credit and in the currency paid or to be paid by such Issuing Lender. Notwithstanding the foregoing, if, after the issuance of any Letter of Credit denominated in a Foreign Currency, such currency ceases to be an Agreed Currency as provided in the definition of Agreed Currency, then all payments to be made by the Borrower hereunder in such currency shall instead be made when due (either directly by the Borrower or through a deemed borrowing under clause (i) below) in Dollars in an amount equal to the Dollar Amount (as of the date of repayment) of such payment due, it being the intention of the parties hereto that the Borrower take all risks of the imposition of any such currency control or exchange regulations. In the event an Issuing Lender makes a payment pursuant to a request for draw presented under a Letter of Credit and such payment is not promptly reimbursed by the Borrower as required herein, such Issuing Lender shall give notice of such payment to the Administrative Agent (which the Administrative Agent will promptly forward to the Lenders). In such event, the Borrower shall be deemed to have requested a Mandatory Revolving Borrowing consisting of (i) for unreimbursed drawings under Letters of Credit denominated in Dollars or in a Foreign Currency which ceased to be an Agreed Currency, Adjusted Base Rate Advances, and (ii) for unreimbursed drawings under Letters of Credit denominated in Foreign Currencies, Eurocurrency Rate Advances in such Agreed Currency and in the amount of such unreimbursed amount with an Interest Period of one month; provided that, if the Revolving Commitments have terminated or otherwise expired, such Eurocurrency Rate Advances shall bear interest at the overnight Eurocurrency Rate. The applicable Issuing Lender shall give the Administrative Agent notice of such deemed Borrowing (A) by 12:00 p.m. (Houston, Texas time) on the date before the proposed Borrowing is to be made in the case of an Adjusted Base Rate Advance or Eurocurrency Rate Advances bearing interest at the overnight Eurocurrency Rate and (B) by 12:00 p.m. (Houston, Texas time) on the fourth Business Day before the date of such proposed Borrowing in the case of a Eurocurrency Rate Advance denominated in a Foreign Currency with an Interest Period of one month (which notice the Administrative Agent shall promptly give to each Lender). Each Lender shall, no later than 1:00 p.m. on the Business Day specified in such notice, promptly make such funds available to the applicable Issuing Lender, in the applicable currency and in an amount equal to such Lender’s Pro Rata Share of the unreimbursed amount. The Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Administrative Agent and the Lenders to record and otherwise treat each payment under a Letter of Credit not immediately reimbursed by the Borrower as a Borrowing comprised of Adjusted Base Rate Advances or Eurocurrency Rate Advances, as applicable, to the Borrower. If for any reason such Mandatory Revolving Borrowing cannot be made by any Lender, the request for such Mandatory Revolving Borrowing submitted by the applicable Issuing Lender as set forth herein shall be deemed to be a request by such Issuing Lender that each of the Lenders fund its risk participation in the relevant Letter of Credit and each Lender’s payment to the Administrative Agent for the account of the applicable Issuing Lender

pursuant to this clause (d) shall be deemed payment in respect of such participation. If the funds are not made available by a Lender to the applicable Issuing Lender on the required date (either as the making of a Revolving Advance or the funding of its participation interest in such Letters of Credit), such Lender shall pay interest thereon to the applicable Issuing Lender at a rate per annum equal to the applicable Overnight Rate. At any time after any Lender has funded its participation in a Letter of Credit, if the applicable Issuing Lender receives any payment on the applicable Reimbursement Obligation from the Borrower, such Issuing Lender will distribute to such Lender its Pro Rata Share of such payment (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s participation was funded) in the same funds as those received by such Issuing Lender. All overdue Reimbursement Obligations of the Borrower shall bear interest as set forth in Section 2.6(e).

(e) Obligations Unconditional. The obligations of the Borrower under this Agreement in respect of each Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, notwithstanding the following circumstances:

(ii) any amendment or waiver of or any consent to departure from any Letter of Credit Documents;

(iii) the existence of any claim, set-off, defense or other right which the Borrower or any Lender or any other Person may have at any time against any beneficiary or transferee of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), any Issuing Lender or any other Person or entity, whether in connection with this Agreement, the transactions contemplated in this Agreement or in any Letter of Credit Documents or any unrelated transaction;

(iv) any statement, draft or any other document presented under such 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 to the extent an Issuing Lender would not be liable therefor pursuant to the following paragraph (f);

(v) payment by an Issuing Lender under such Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit; or

(vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing;

provided, however, that nothing contained in this paragraph (e) shall be deemed to constitute a waiver of any remedies of the Borrower in connection with the Letters of Credit.

(f) Liability of Issuing Lenders. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. No Issuing Lender nor any of its officers or directors shall be liable or responsible for, and the Borrower’s obligations hereunder shall not be affected by:

(i) the use which may be made of any Letter of Credit, any transfer of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith;

(ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged;

(iii) payment by any Issuing Lender against presentation of documents which do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit;

(iv) any adverse change in the relevant exchange rates or in the availability of the relevant Agreed Currency to the Borrower or in the relevant currency markets generally; or

(v) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (INCLUDING ANY ISSUING LENDER’S OWN NEGLIGENCE),

except that the Borrower shall have a claim against such Issuing Lender, and such Issuing Lender shall be liable to, and shall promptly pay to, the Borrower, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower proves were caused by such Issuing Lender’s willful misconduct or gross negligence. In furtherance and not in limitation of the foregoing clause (f), the Issuing Lenders may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary and may refuse to accept documents that are not in strict conformity with the terms of the Letter of Credit, and any such acceptance or refusal shall not be deemed to constitute gross negligence or willful misconduct.

(g) Cash Collateral Account. The Borrower shall, (i) within 10 days prior to the Maturity Date and (ii) at any time, if an Event of Default has occurred and is continuing, on the Business Day the Borrower receives written notice from an Issuing Lender or the Administrative Agent that collateralization is being required pursuant to Section 7.2(b) or Section 7.3(b), either (A) provide Cash Collateral in an amount equal to the Letter of Credit Exposure as of such date or (B) cause to be issued an irrevocable standby letter of credit in favor of the applicable Issuing Lender and issued by a bank or other financial institution acceptable to such Issuing Lender and the Administrative Agent to support the full amount of the Letter of Credit Exposure as of such date. With respect to Letters of Credit issued in Foreign Currencies, if the Borrower elects to provide Cash Collateral pursuant to clause (A) above, then at the election of the Administrative Agent, the Borrower shall be required to either (1) deposit cash with the Administrative Agent in the Designated Currencies for the Letters of Credit or (2) deposit cash with the Administrative Agent in Dollars equal to the Dollar Amount of the Letter of Credit Exposure and, thereafter, deposit additional cash in Dollars at any time and from time to time as may be reasonably requested by the Administrative Agent in order to protect against the results of exchange rate fluctuations.

(h) Letters of Credit Issued for Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Subsidiary of the Borrower, the Borrower shall be obligated to reimburse the applicable Issuing Lender hereunder for any and all drawings under such Letter of Credit. The Borrower hereby acknowledges that the issuance of Letters of Credit for the account of Subsidiaries inures to the benefit of the Borrower, and that the Borrower’s business derives substantial benefits from the businesses of such Subsidiaries.

(i) Information to Administrative Agent from Issuing Lenders. For purposes of calculating outstandings and Letters of Credit issued under this Agreement (i) on each March 31, June 30, September 30 and December 31, commencing September 30, 2012, and (ii) from time to time as the Administrative Agent may request, each Issuing Lender shall provide the Administrative Agent with a daily log, in form and detail reasonably acceptable to the Administrative Agent, setting forth the Dollar Amount of all outstanding Letters of Credit issued by such Issuing Lender using the Exchange Rate as most recently determined by the Administrative Agent.

Section 2.14 Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off or otherwise) on account of its Advances or its share of Letter of Credit Obligations in excess of its Pro Rata Share of payments on account of the Advances or Letter of Credit Obligations obtained by all the Lenders, then such Lender shall notify the Administrative Agent and the other Lenders and forthwith purchase from the other Lenders, such participations in the Advances made by them or Letter of Credit Obligations held by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably in accordance with the requirements of this Agreement with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender’s ratable share (according to the proportion of (a) the amount of the participation sold by such Lender to the purchasing Lender as a result of such excess payment to (b) the total amount of such excess payment) of such recovery, together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to the purchasing Lender to (ii) the total amount of all such required repayments to the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.14 may, to the fullest extent permitted by law, unless and until rescinded as provided above, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

(a) At any time prior to the Maturity Date, the Borrower may effectuate no more than two increases in the aggregate Revolving Commitments by an aggregate amount not greater than $1,000,000,000 (any such increase, a “Commitment Increase”), by designating either one or more of the existing Lenders (each of which, in its sole discretion, may determine whether and to what degree to participate in such Commitment Increase) or one or more other banks or other financial institutions (reasonably acceptable to the Administrative Agent, the Issuing Lenders and the Swingline Lenders) that at the time agree, in the case of any such bank or financial institution that is an existing Lender to increase its Revolving Commitment as such Lender shall so select (an “Increasing Lender”) and, in the case of any other such bank or financial institution (an “Additional Lender”), to become a party to this Agreement; provided, however, that (i) the aggregate Revolving Commitments shall not at any time exceed $4,500,000,000 and (ii) the minimum amount of each such Commitment Increase shall not be less than $100,000,000. The sum of the increases in the Revolving Commitments of the Increasing Lenders plus the Revolving Commitments of the Additional Lenders upon giving effect to the Commitment Increase shall not in the aggregate exceed the amount of the Commitment Increase. The Borrower shall provide prompt notice of any proposed Commitment Increase pursuant to this Section 2.15 to the Administrative Agent and the Lenders.

(b) Any Commitment Increase shall become effective upon (i) the receipt by the Administrative Agent of (A) an agreement in form and substance satisfactory to the Administrative Agent signed by the Borrower, each Increasing Lender and each Additional Lender, setting forth the new Revolving Commitment of each such Lender and setting forth the agreement of each Additional Lender to become a party to this Agreement and to be bound by all the terms and provisions hereof binding upon each Lender, and (B) such evidence of appropriate authorization on the part of the Borrower with respect to the Commitment Increase and such opinions of counsel for the Borrower with respect to the Commitment Increase as the Administrative Agent may reasonably request, and (ii) receipt by the

Administrative Agent of a certificate (the statements contained in which shall be true) of a Responsible Officer of the Borrower stating that both before and after giving effect to such Commitment Increase (A) no Event of Default has occurred and is continuing, and (B) all representations and warranties made by the Borrower in this Agreement are true and correct in all material respects, unless such representation or warranty relates to an earlier date.

(c) The Borrower shall prepay any Advances outstanding on the effective date of such Commitment Increase to the extent necessary to keep the outstanding Revolving Advances ratable with any revised Pro Rata Share arising from any nonratable increases in the Revolving Commitments under this Section 2.15.

(d) Notwithstanding any provision contained herein to the contrary, from and after the date of any Commitment Increase, all calculations and payments of interest on the Advances shall take into account the actual Revolving Commitment of each Lender and the principal amount outstanding of each Advance made by such Lender during the relevant period of time.

Section 2.16 Mitigation Obligations; Lender Replacement; Termination of Defaulting Lender.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 2.9, or requires the Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.11, then such Lender shall (at the request of the Borrower) use reasonable efforts to designate a different lending office for funding or booking its Advances hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.9 or 2.11, as the case may be, in the future, and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designatifon or assignment.

(b) Right to Replace. The Borrower shall have the right to replace each Lender affected by a condition under Sections 2.2(c)(v), 2.2(c)(viii), 2.9, 2.11 or 2.12, each Lender that is a Defaulting Lender, a Non-Approving Lender or a Non-Consenting Lender and each Lender that is due interest based on the Mandatory Cost Rate (each such Lender, an “Affected Lender”) in accordance with the procedures in this Section 2.16 and provided that (i) no reduction of the total Revolving Commitments occurs as a result thereof, (ii) such Affected Lender has declined or is unable to designate a different lending office in accordance with Section 2.16(a) to remedy any such condition, (iii) the condition entitling the Borrower to require such replacement has not ceased to apply and (iv) such assignment does not conflict with applicable law.

(c) Procedure. Any assumptions of Revolving Commitments pursuant to this Section 2.16 shall be made by the purchasing Lender or Eligible Assignee and the selling Lender by entering into an Assignment and Assumption and by following the procedures in Section 9.6 for adding a Lender; provided that the Borrower or the assignee (if such assignee is not the Administrative Agent or its Affiliate) shall have paid to the Administrative Agent the assignment fee (if any) specified in Section 9.6(a), which may be waived by the Administrative Agent in its sole discretion. In connection with the increase of the Revolving Commitments of any Lender or the introduction of any Eligible Assignee pursuant to the foregoing paragraph (b), each Lender with an increased Revolving Commitment and each new Eligible Assignee shall purchase from the Affected Lenders at par such Lender’s or such new Lender’s ratable share of the outstanding Advances, funded participations, accrued interest thereon and accrued fees of the Affected Lenders (and provided that the Borrower shall be obligated to pay any other amounts payable to any such Affected Lender under the Credit Documents, including pursuant to Section 2.8 hereof) and shall be automatically deemed to have assumed such Lender’s or such new Lender’s ratable share of the Affected Lenders’ participations in Letter of Credit Exposure.

(i) Entire Revolving Commitment. At any time when a Lender is then a Defaulting Lender, the Borrower, at the Borrower’s election, may elect to terminate such Defaulting Lender’s Revolving Commitment hereunder; provided that (A) the Borrower must elect to terminate such Defaulting Lender’s entire Commitment, (B) the Borrower shall pay to the Administrative Agent all amounts owed by the Borrower to such Defaulting Lender in its capacity as a Lender under this Agreement and under the other Credit Documents (excluding any amounts owing under Section 2.8 as result of such payment) and shall, to the extent such Defaulting Lender’s ratable share of the Letter of Credit Exposure has not been, or has only partially been, reallocated pursuant to Section 2.20(a)(iv), deposit with the Administrative Agent into the Cash Collateral Account cash collateral in the amount equal to such Defaulting Lender’s Fronting Exposure (after giving effect to any partial reallocation pursuant to Section 2.20(a)(iv)), (C) a Defaulting Lender’s Revolving Commitment may be terminated by the Borrower under this Section 2.16(d) only if at such time, the Borrower has elected, or is then electing, to terminate the Revolving Commitments of all then existing Defaulting Lenders and (D) such termination shall not be permitted if a Default has occurred and is continuing. Upon written notice to the Defaulting Lender and the Administrative Agent of the Borrower’s election to terminate such Defaulting Lender’s Commitment pursuant to this clause (i) and the payment and deposit of amounts required to be made by the Borrower under clause (B) above, (1) such Defaulting Lender shall cease to be a “Lender” hereunder for all purposes except that such Lender’s rights and obligations as a Lender under Sections 2.9, 2.11, 8.5 and 9.7 shall continue with respect to events and occurrences occurring before or concurrently with its ceasing to be a “Lender” hereunder, (2) such Defaulting Lender’s Revolving Commitment shall be deemed terminated in whole and (3) such Defaulting Lender shall be relieved of its obligations hereunder as a “Lender” except as to its obligations under Section 8.5 with respect to events and occurrences occurring before or concurrently with its ceasing to be a “Lender” hereunder, provided that any such termination will not be deemed to be a waiver or release of any claim by the Borrower, the Administrative Agent, any Swing Line Lender, any Issuing Lender or any Lender against such Defaulting Lender.

(ii) Unused Commitment Termination. The Borrower may terminate the unused amount of the Revolving Commitment of any Lender that is a Defaulting Lender upon not less than 30 Business Days’ prior notice to the Administrative Agent (which shall promptly notify the Lenders thereof), and in such event the provisions of Section 2.20(a)(ii) will apply to all amounts thereafter paid by the Borrower for the account of such Defaulting Lender under this Agreement (whether on account of principal, interest, fees, indemnity or other amounts); provided that (i) no Event of Default shall have occurred and be continuing, (ii) such termination shall not be deemed to be a waiver or release of any claim the Borrower, the Administrative Agent, any Issuing Lender, the Swingline Lender or any Lender may have against such Defaulting Lender, and (iii) to the extent such Defaulting Lender’s ratable share of the Letter of Credit Exposure has not been, or has only partially been, reallocated pursuant to Section 2.20(a)(iv), the Borrower shall deposit with the Administrative Agent into the Cash Collateral Account cash collateral in the amount equal to such Defaulting Lender’s Fronting Exposure (after giving effect to any partial reallocation pursuant to Section 2.20(a)(iv)).

Section 2.17 Currency Fluctuations, Mandatory Prepayments and Deposits in the Cash Collateral Accounts.

(a) Not later than 1:00 p.m., Houston, Texas time, on each Computation Date, the Administrative Agent shall determine the Exchange Rate as of such Computation Date and give notice thereof to the Borrower, each Lender, Swingline Lender and Issuing Lender. The Exchange Rate so determined shall become effective on the first Business Day after such Computation Date and shall remain effective through the next succeeding Computation Date.

(b) If, on any Computation Date, the Dollar Amount of the sum of the outstanding principal amount of Revolving Advances plus the outstanding principal amount of Swingline Advances plus the Letter of Credit Exposure exceeds an amount equal to 102% of the aggregate Revolving Commitments then in effect, then the Administrative Agent shall give notice thereof to the Borrower and the Lenders, and the Borrower shall within five (5) Business Days thereafter prepay Advances, or if the Advances have been repaid or prepaid in full, make deposits into the Cash Collateral Account, such that after giving effect to such prepayment of Advances or deposits into the Cash Collateral Account, the Dollar Amount of the sum of the outstanding principal amount of Revolving Advances plus the outstanding principal amount of Swingline Advances plus the Letter of Credit Exposure does not exceed the aggregate Revolving Commitments then in effect.

(c) If any currency shall cease to be an Agreed Currency as provided in the last sentence of the definition of “Agreed Currency”, then promptly, but in any event within five (5) Business Days of receipt of the notice from the Administrative Agent provided for in such sentence, the Borrower shall repay all Advances funded and denominated in such affected currency or Convert such Advances into Advances in Dollars or another Agreed Currency, subject to the other terms set forth in Article II.

(d) Each prepayment pursuant to this Section 2.17 shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.8 as a result of such prepayment being made on such date.

(e) Each payment of any Advance pursuant to this Section 2.17 or any other provision of this Agreement shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part and each payment of an Advance shall be made in the Designated Currency in which such Advance was funded.

Section 2.18 Market Disruption. Notwithstanding the satisfaction of all conditions referred to herein with respect to any proposed Borrowing consisting of Eurocurrency Advances denominated in any Foreign Currencies, if there shall occur on or prior to the date of such Borrowing any change in national or international financial, political or economic conditions or currency exchange rates or exchange controls which would in the reasonable opinion of the Administrative Agent or the Majority Lenders, make it impracticable for such Borrowing to be denominated in the Agreed Currency designated by the Borrower, then the Administrative Agent shall forthwith give notice thereof to the Borrower and the Lenders, and such Advances shall not thereafter be denominated and funded in such Agreed Currency but shall, except as otherwise set forth in Article II, be made on such date in Dollars, in an aggregate principal amount equal to the Dollar Amount of the aggregate principal amount specified in the related Notice of Borrowing, as the case may be, as Adjusted Base Rate Advances to the Borrower, unless the Borrower notifies the Administrative Agent at least one Business Day before such date that it elects not to borrow on such date.

(a) Not earlier than 90 days prior to, nor later than 30 days prior to, each anniversary of the Closing Date, the Borrower may, upon notice to the Administrative Agent (which shall promptly notify the Lenders), request a one year extension of the Maturity Date then in effect (the “Present Maturity Date”). This option may be exercised only twice. Within 30 days of delivery of such notice, each Lender shall notify the Administrative Agent whether or not it consents to such extension (which consent may be given or withheld in such Lender’s sole and absolute discretion). Any Lender not responding within the above time period shall be deemed not to have consented to such extension. The Administrative Agent shall promptly notify the Borrower and the Lenders of the Lenders’ responses.

(b) The Maturity Date shall be extended only if the consenting Lenders (the “Consenting Lenders”) constitute Majority Lenders and only if the Revolving Commitments of the Consenting Lenders are at least equal to the Outstandings, after giving effect to the prepayment of Advances to Non-Consenting Lenders. If so extended, the Maturity Date, as to the Consenting Lenders, shall be extended to the same date in the following year, effective as of the Maturity Date then in effect (such extended Maturity Date being the “Extension Maturity Date”). All non consenting Lenders (“Non-Consenting Lenders”) shall continue to be subject to the Maturity Date in effect prior to the effectiveness of the Extension Maturity Date (such existing Maturity Date being the “Present Maturity Date”). The Administrative Agent and the Borrower shall promptly confirm to the Lenders such extension and the Extension Maturity Date. As a condition precedent to such extension, the Borrower shall pay or prepay all Advances, interest thereon and all other amounts due each Non-Consenting Lender on or before the Present Maturity Date, and shall deliver to the Administrative Agent a certificate of the Borrower (in sufficient copies for each Lender) signed by a Responsible Officer of the Borrower (i) certifying and attaching the resolutions adopted by the Borrower approving or consenting to such extension and (ii) certifying that, before and after giving effect to such extension, (A) the representations and warranties contained in Article IV and the other Credit Documents are true and correct in all material respects, except to the extent that such representations and warranties expressly relate solely to an earlier date, in which case they shall have been true and correct in all material respects as of such earlier date, and except that for purposes of this Section 2.19, the representations and warranties contained in Section 4.6 shall be deemed to refer to the most recent statements furnished pursuant to subsection (b) of Section 5.6, and (B) no Default exists. If the Maturity Date has been extended, each Consenting Lender shall automatically be deemed to have purchased participations in each Letter of Credit, the related Letter of Credit Exposure, and each Swingline Advance equal to such Consenting Lender’s Pro Rata Share thereof after giving effect to the departure of the Non-Consenting Lenders and the elimination of their Revolving Commitments.

(d) The Borrower shall prepay any Advances outstanding on the Present Maturity Date (and pay any additional amounts required pursuant to Section 2.8) or borrow additional amounts to the extent necessary to keep outstanding Revolving Advances ratable with any revised and new Revolving Commitment of all Consenting Lenders effective as of the Present Maturity Date.

(a) Defaulting Lender Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

(i) Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of Majority Lenders.

(ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VII or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 7.6 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 such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to any Issuing Lender or Swingline Lender hereunder; third, to Cash Collateralize, on a pro rata basis, the Issuing Lenders’ and the Swingline Lenders’ Fronting Exposure with respect to such Defaulting Lender in accordance with Section 2.20(b); fourth, as the Borrower may request (so long as no Default exists), to the funding of any Advance in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Advances under this Agreement and (y) Cash Collateralize the Issuing Lenders’ and the Swingline Lenders’ future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement and Swingline Advances made under this Agreement, in accordance with Section 2.20(b); sixth, to the payment of any amounts owing to the Lenders, the Issuing Lenders or Swingline Lenders as a result of any judgment of a court of competent jurisdiction obtained by any Lender, the Issuing Lenders or Swingline Lenders against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no 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 such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Advances or Letters of Credit in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Advances were made or the related Letters of Credit were issued at a time when the conditions set forth in Sections 3.2 and 3.3 were satisfied or waived, such payment shall be applied solely to pay the Advances of, and Letter of Credit Obligations owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Advances of, or Letter of Credit Obligations owed to, such Defaulting Lender until such time as all Advances and funded and unfunded participations in Letters of Credit and Swingline Advances are held by the Lenders pro rata in accordance with the Revolving Commitments without giving effect to Section 2.20(a)(iv). 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 this Section 2.20(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(A) No Defaulting Lender shall be entitled to receive any Commitment Fee for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(B) Each Defaulting Lender shall be entitled to receive fees set forth in Section 2.3(b) for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Pro Rata Share of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 2.20(b).

(C) With respect to any fee not required to be paid to any Defaulting Lender pursuant to clause (B) above, the Borrower shall (x) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in Letters of Credit that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to each Issuing Lender the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to such Issuing Lender’s Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such fee.

(iv) Reallocation of Participations to Reduce Fronting Exposure. All or any part of such Defaulting Lender’s participation in Letters of Credit and Swingline Advances shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Pro Rata Shares of the aggregate amount of the Revolving Commitment (calculated without regard to such Defaulting Lender’s Revolving Commitment) but only to the extent that (x) the conditions set forth in Sections 3.2 and 3.3 are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause any Non-Defaulting Lender’s Pro Rata Share of the Aggregate Exposure to exceed such Non-Defaulting Lender’s Revolving Commitment. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation.

(b) Cash Collateral; Prepayment of Swingline. At any time that there shall exist a Defaulting Lender, within one Business Day following the written request of the Administrative Agent or any Issuing Lender (with a copy to the Administrative Agent), the Borrower shall Cash Collateralize the Issuing Lenders’ Fronting Exposure, as requested, with respect to such Defaulting Lender (determined after giving effect to Section 2.20(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount not less than the applicable Minimum Collateral Amount. At any time that there shall exist a Defaulting Lender, within one Business Day following the written request of the Administrative Agent or any Swing Line Lender (with a copy to the Administrative Agent), the Borrower shall either (i) Cash Collateralize the Swingline Lenders’ Fronting Exposure, as requested, with respect to such Defaulting Lender (determined after giving effect to Section 2.20(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount not less than the applicable Minimum Collateral Amount or (ii) prepay Swingline Advances in an amount equal to the Swingline Lenders’ Fronting Exposure as to Swingline Advances.

(i) Grant of Security Interest. The Borrower, and to the extent provided by any Defaulting Lender, such Defaulting Lender to the extent not prohibited under applicable law, hereby grants to the Administrative Agent, for the benefit of the Issuing Lenders and the Swingline Lenders, and agrees to maintain, a first priority security interest in all such Cash Collateral as security for the Defaulting Lenders’ obligation to fund participations in respect of Letter of Credit Obligations and Swingline Advances, to be applied pursuant to clause (ii) below and the introductory paragraph of this Section 2.20(b). If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the

Administrative Agent, the Issuing Lenders, and the Swingline Lenders, or that the total amount of such Cash Collateral is less than the Minimum Collateral Amount, the Borrower will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by the Defaulting Lender).

(ii) Application. Notwithstanding anything to the contrary contained in this Agreement but subject to the introductory paragraph of this Section 2.20(b), (A) Cash Collateral provided under this Section 2.20(b) in respect of Letters of Credit shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of Letter of Credit Obligations (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein and (B) Cash Collateral provided under this Section 2.20(b) in respect of Swingline Advances shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of Swingline Advances (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(iii) Cash Collateral, Repayment of Swingline Advances. If the reallocation described in Section 2.20(a)(iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under law, (x) first prepay or Cash Collateralize the Swingline Advances as set forth above in this Section 2.20(b), and (y) second, Cash Collateralize the Issuing Lenders’ Fronting Exposure as set forth above in this Section 2.20(b).

(iv) Termination of Requirement. Cash Collateral (or the appropriate portion thereof) provided to reduce any Issuing Lender’s or any Swingline Lender’s Fronting Exposure shall no longer be required to be held as Cash Collateral pursuant to this Section 2.20(b) following (i) the elimination of the applicable Fronting Exposure (including by the termination of Defaulting Lender status of the applicable Lender) with respect to Letters of Credit and Swingline Advances, or (ii) the determination by the Administrative Agent, each Swingline Lender and each Issuing Lender that there exists excess Cash Collateral; provided that, the Person providing Cash Collateral, the Issuing Lenders and the Swingline Lenders may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure or other obligations.

Section 8.1 Authorization and Action. Each Lender hereby appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement and the other Credit Documents as are delegated to the Administrative Agent by the terms

hereof and of the other Credit Documents, together with such powers as are reasonably incidental thereto. As to any matters not expressly provided for by this Agreement or any other Credit Document (including enforcement or collection of the Obligations), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority Lenders or all Lenders, and such instructions shall be binding upon all Lenders and all holders of the Obligations; provided, however, that Administrative Agent shall not be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, any other Credit Document, or applicable Legal Requirements. It is understood and agreed that the use of the term “agent” herein or in any other Credit Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

Section 8.2 Administrative Agent’s Reliance, Etc. Neither Administrative Agent nor any of its respective directors, officers, agents or employees shall be liable for any action taken or omitted to be taken (INCLUDING THE ADMINISTRATIVE AGENT’S OWN NEGLIGENCE) by it or them under or in connection with this Agreement or the other Credit Documents, except for its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Administrative Agent: (a) may treat the payee of any Note as the holder thereof until the Administrative Agent receives written notice of the assignment or transfer thereof signed by such payee and in form satisfactory to the Administrative Agent; (b) may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations made in or in connection with this Agreement or the other Credit Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement or any other Credit Document on the part of the Borrower or its Subsidiaries or to inspect the property (including the books and records) of the Borrower or its Subsidiaries; (e) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other Credit Document; and (f) shall incur no liability under or in respect of this Agreement or any other Credit Document by acting upon any notice, consent, certificate or other instrument or writing (which may be by facsimile, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper party or parties.

Section 8.3 The Administrative Agent and its Affiliates. With respect to its Revolving Commitments, the Advances made by it and the Letters of Credit issued by it, the Administrative Agent shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not an agent hereunder. The term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include the Administrative Agent in its individual capacity. Administrative Agent and its respective Affiliates may accept deposits from, lend money to, own securities of, act as trustee under indentures of, and generally engage in any kind of business with, the Borrower or any of its Subsidiaries, and any Person who may do business with or own securities of the Borrower or any such Subsidiary, all as if the Administrative Agent were not an agent hereunder and without any duty to account therefor to the Lenders.

Section 8.4 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, the Arrangers or any other Lender and based on the financial statements referred to in Section 4.6 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent, the Arrangers or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.

Section 8.5 Indemnification. The Lenders severally agree to indemnify the Administrative Agent, each Arranger, each Swingline Lender and each Issuing Lender (to the extent not reimbursed by the Borrower), according to their respective Pro Rata Shares from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including legal fees) which may be imposed on, incurred by, or asserted against the Administrative Agent, such Arranger or such Issuing Lender in any way relating to or arising out of this Agreement or any other Credit Document or any action taken or omitted by the Administrative Agent, such Arranger, such Swingline Lender or such Issuing Lender under this Agreement or any other Credit Document (INCLUDING THE ADMINISTRATIVE AGENT’S, THE ARRANGER’S, SUCH SWINGLINE LENDER’S OR SUCH ISSUING LENDER’S OWN NEGLIGENCE), provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements found by a final judgment by a court of competent jurisdiction to have resulted from the Administrative Agent’s, such Arranger’s, such Swingline Lender’s or such Issuing Lender’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to (a) reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, modification or amendment of this Agreement or any other Credit Document, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrower and (b) reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the administration or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement or any other Credit Document, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrower. All obligations of the Lenders provided in this Section 8.5 shall survive any termination of this Agreement and repayment in full of the Obligations. All amounts due under this Section 8.5 shall be payable not later than 30 days after demand therefor.

(a) Administrative Agent and any Issuing Lender may resign at any time by giving written notice thereof to the Lenders and the Borrower. The Administrative Agent and any Issuing Lender may be removed at any time with or without cause by the Majority Lenders upon receipt of written notice from such Majority Lenders to such effect. Any Issuing Lender designated in writing by the Borrower as provided in the definition of “Issuing Lender” may be removed at any time with or without cause by the Borrower. Upon receipt of notice of any such resignation or removal (other than a removal of an Issuing Lender by the Borrower), the applicable Majority Lenders shall have the right to appoint a successor Administrative Agent or Issuing Lender with, if an Event of Default has not occurred and is not continuing, the consent of the Borrower, which consent shall not be unreasonably withheld or delayed. If no successor Administrative Agent or Issuing Lender shall have been so appointed by the Majority Lenders, and shall have accepted such appointment, within 30 days after the retiring or removed Administrative Agent’s or Issuing Lender’s giving of notice of resignation or the Majority Lenders’ removal of the retiring Administrative Agent or Issuing Lender, then the retiring or removed Administrative Agent or Issuing Lender may, on behalf of the Lenders and the Borrower, appoint a successor Administrative Agent or Issuing Lender, which shall be a commercial bank meeting the financial requirements of an Eligible Assignee and, in the case of a Issuing Lender, a Lender. Upon the acceptance of any appointment as Administrative Agent or Issuing Lender by a successor Administrative Agent or Issuing Lender, such successor Administrative Agent or Issuing Lender shall thereupon succeed

to and become vested with all the rights, powers, privileges and duties of the retiring or removed Administrative Agent or Issuing Lender (other than any rights to indemnity payments owed to the retiring or removed Administrative Agent or Issuing Lender), and the retiring or removed Administrative Agent or Issuing Lender shall be discharged from its duties and obligations under this Agreement and the other Credit Documents, except that the retiring or removed Issuing Lender shall remain the Issuing Lender with respect to any Letters of Credit issued by such Issuing Lender and outstanding on the effective date of its resignation or removal and the provisions affecting such Issuing Lender with respect to such Letters of Credit shall inure to the benefit of the retiring or removed Issuing Lender until the termination of all such Letters of Credit and the payment of all outstanding Obligations owing to such Issuing Lender. After any retiring or removed Administrative Agent’s or Issuing Lender’s resignation or removal hereunder as Administrative Agent or Issuing Lender, the provisions of this Article VIII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent or Issuing Lender under this Agreement and the other Credit Documents (including rights to indemnity payments owed to the retiring or removed Administrative Agent or Issuing Lender).

After the resignation of such Swing Line Lender hereunder, the resigning Swing Line Lender shall remain a party hereto and shall continue to have all the rights and obligations of such Swing Line Lender under this Agreement and the other Loan Documents with respect to Swing Line Advances made by it prior to such resignation, but shall not be required to make any additional Swing Line Advances. Upon such notice of resignation, the Borrower shall have the right to designate any other Lender as a replacement Swing Line Lender with the consent of such Lender and the Administrative Agent.

Each Lender agrees (A) to notify, on or before the date such Lender becomes a party to this Agreement, the Administrative Agent in writing of such Lender’s e-mail address to which a Notice may be sent (and from time to time thereafter to ensure that the Administrative Agent have on record an effective e-mail address for such Lender) and (B) that any Notice may be sent to such e-mail address.

Section 9.3 No Waiver; Remedies. No failure on the part of any Lender, the Administrative Agent, or any Issuing Lender to exercise, and no delay in exercising, any right hereunder or under any other Credit Document shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies provided in this Agreement and the other Credit Documents are cumulative and not exclusive of any remedies provided by law.

Section 9.4 Costs and Expenses. The Borrower agrees to pay on demand (a) all out-of-pocket costs and expenses of the Administrative Agent in connection with the preparation, execution, delivery, modification and amendment of this Agreement, the Notes and the other Credit Documents, (b) all out-of-pocket costs and expenses of the Issuing Lenders and Swingline Lenders in connection with the administration of this Agreement, the Notes and the other Credit Documents, including the reasonable out-of-pocket expenses incurred by any Issuing Lender in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (c) all reasonable out-of-pocket costs and expenses, if any, of the Administrative Agent, each Arranger, each Issuing Lender, each Swingline Lender and each Lender (including reasonable counsel fees and expenses of the Administrative Agent, each Arranger, each Issuing Lender, each Swingline Lender and each Lender) in connection with the enforcement (whether through negotiations, legal proceedings or otherwise) of this Agreement and the other Credit Documents after an Event of Default has occurred and is continuing, and to the extent not included in the foregoing, the costs of any Uniform Commercial Code financing statement or continuation statement, and any related title or Uniform Commercial Code search conducted subsequent to such recordation, and other costs usual and customary in connection with the taking of a Lien.

Section 9.5 Binding Effect. This Agreement shall become effective when it shall have been executed by the Borrower and the Administrative Agent, and when the Administrative Agent shall have, as to each Lender, either received a counterpart hereof executed by such Lender or been notified by such Lender that such Lender has executed it and thereafter shall be binding upon and inure to the benefit of the Borrower, the Administrative Agent, each Arranger, each Issuing Lender, each Swingline Lender and each Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights or delegate its duties under this Agreement or any interest in this Agreement without the prior written consent of each Lender, each Swingline Lender, and each Issuing Lender.

(a) Assignments. Any Lender may assign to one or more banks or other entities all or any portion of its rights and obligations under this Agreement (including all or a portion of its Revolving Commitment, the Advances owing to it, the Notes held by it, if any, and the participation interest in the Letter of Credit Obligations held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all of such Lender’s rights and obligations under this Agreement as a Lender and shall involve a ratable assignment of such Lender’s Revolving Commitment and such Lender’s Revolving Advances and shall be in an amount not less than $5,000,000, (ii) the amount of the resulting Revolving Commitment and Revolving Advances of the assigning Lender (unless it is assigning all its Revolving Commitment) and the assignee Lender pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $10,000,000, (iii) each such assignment shall be to an Eligible Assignee, (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with the applicable Notes, if any, subject to such assignment, (v) each Eligible Assignee shall pay to the Administrative Agent a $4,000 administrative fee; and (vi) the Administrative Agent shall promptly deliver a copy of the fully executed Assignment and Acceptance to the Administrative Agent. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, which effective date shall be at least three Business Days after the execution thereof, (A) the assignee thereunder shall be a party hereto for all purposes and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (B) such Lender thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of such Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.8, 2.9, 2.11, 9.4, 9.7 and 9.16 with respect to facts and circumstances occurring prior to the effective date of such assignment. Notwithstanding anything herein to the contrary, any Lender may assign, as collateral or otherwise, any of its rights under the Credit Documents to any Federal Reserve Bank.

(b) Term of Assignments. By executing and delivering an Assignment and Acceptance, the Lender thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 4.6 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Administrative Agent, such Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

(c) The Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in the United States a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated interest) of the Advances owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Administrative Agent, the Issuing Lenders, and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. At any reasonable time and from time to time upon reasonable prior notice, the Register shall be available (i) for inspection by the Borrower, (ii) for inspection by each Lender as to its Revolving Commitment and principal amount of Advances owing to it, and (iii) for inspection by each Issuing Lender and each Swingline Lender for purposes of determining each Lender’s participation interest in Letters of Credit and Swingline Advances. The Borrower hereby agrees that the Administrative Agent acting as its agent solely for the purpose set forth above in this clause (c), shall not subject the Administrative Agent to any fiduciary or other implied duties, all of which are hereby waived by the Borrower.

(d) Procedures. Upon its receipt of an Assignment and Acceptance executed by a Lender and an Eligible Assignee, together with the Notes, if any, subject to such assignment, the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of the attached Exhibit A, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register, and (iii) give prompt notice thereof to the Borrower.

(e) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural Person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Advances owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and (iii) the Borrower, the Administrative Agent, the Issuing Lenders, the Swingline Lenders and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity and other obligations under Section 8.5 with respect to any payments made by such Lender to its Participant(s).

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that requires the approval of all affected Lenders in accordance with the terms of Section 9.1 that affects such Participant. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.8, 2.9 and 2.11 (subject to the requirements and limitations therein) (it being understood that the documentation required under Section 2.11(g) shall be delivered to the participating Lender and delivered to the Borrower as required under Section 2.11(g)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 9.6(a); provided that such Participant (A) agrees to be subject to the provisions of Section 2.16 as if it were an assignee under Section 9.6(a); and (B) shall not be entitled to receive any greater payment under Sections 2.9 or 2.11, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after

the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower’s request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 2.16 with respect to any Participant. To the extent permitted by Legal Requirement, each Participant also shall be entitled to the benefits of Section 7.6 as though it were a Lender; provided that such Participant agrees to be subject to Section 2.14 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Advances or other obligations under the Credit Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Credit Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register. The Borrower hereby agrees that each Lender acting as its agent solely for the purpose set forth above in this clause (e), shall not subject such Lender to any fiduciary or other implied duties, all of which are hereby waived by the Borrower

(f) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(g) Information. Any Lender may furnish any information concerning the Borrower or any of its Subsidiaries in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants), subject, however, to the provisions of Section 9.12.

(h) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Advances previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, each Issuing Lender, each Swingline Lender and each other Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Advances and participations in Letters of Credit and Swingline Advances in accordance with its Pro Rata Share. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs. Except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

Section 9.7 Indemnification. The Borrower shall indemnify the Administrative Agent, each Arranger, each Lender (including any lender which was a Lender hereunder prior to any full assignment of its Revolving Commitment), each Issuing Lender, each Swingline Lender and each affiliate thereof and their respective directors, officers, employees and agents from, and discharge, release, and hold each of them harmless against, any and all losses, liabilities, claims or damages to which any of them may become subject, insofar as such losses, liabilities, claims or damages arise out of or result from (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or any other transactions contemplated hereby, (ii) any actual or proposed use by the Borrower or any Affiliate of the Borrower of the proceeds of any Advance or Letter of Credit, (iii) any breach by the Borrower of any provision of this Agreement or any other Credit Document, (iv) any Environmental Claim or requirement of Environmental Laws concerning or relating to the present or previously-owned or operated properties, or the operations or business, of the Borrower or any of its Subsidiaries, and (v) any investigation, litigation or other proceeding (including any threatened investigation or proceeding) relating to the foregoing, and the Borrower shall reimburse the Administrative Agent, each Arranger, the Issuing Lender, each Swingline Lender and each Lender, and each affiliate thereof and their respective directors, officers, employees and agents, upon demand for any reasonable out-of-pocket expenses (including legal fees) incurred in connection with any such losses, liabilities, claims, damages, investigation, litigation, Environmental Claim or requirement, or other proceeding; and EXPRESSLY INCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES, OR EXPENSE INCURRED BY REASON OF THE PERSON BEING INDEMNIFIED’S OWN NEGLIGENCE, BUT EXCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES OR EXPENSES FOUND BY A FINAL JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PERSON TO BE INDEMNIFIED. All amounts due under this Section 9.7 shall be payable not later than 30 days after demand therefor.

Section 9.8 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

Section 9.9 Survival of Representations, etc. All representations and warranties contained in this Agreement or made in writing by or on behalf of the Borrower in connection herewith shall survive the execution and delivery of this Agreement and the Credit Documents, the making of the Advances and any investigation made by or on behalf of the Lenders, none of which investigations shall diminish any Lender’s right to rely on such representations and warranties. All obligations of the Borrower provided for in Sections 2.8, 2.9, 2.11, 9.4, 9.7 and 9.16 shall survive any termination of this Agreement and repayment in full of the Obligations.

Section 9.10 Severability. In case one or more provisions of this Agreement or the other Credit Documents shall be invalid, illegal or unenforceable in any respect under any applicable Legal Requirement, the validity, legality and enforceability of the remaining provisions contained herein or therein shall not be affected or impaired thereby.

Section 9.11 Usury Not Intended. It is the intent of the Borrower and each Lender in the execution and performance of this Agreement and the other Credit Documents to contract in strict compliance with applicable usury laws, including conflicts of law concepts, governing the Advances of each Lender including such applicable Legal Requirements of the State of Texas and the United States of America from time to time in effect. In furtherance thereof, each Lender and the Borrower stipulate and agree that none of the terms and provisions contained in this Agreement or the other Credit Documents shall ever be construed to create a contract to pay, as consideration for the use, forbearance or detention of

money, interest at a rate in excess of the Maximum Rate and that for purposes hereof “interest” shall include the aggregate of all charges which constitute interest under such laws that are contracted for, charged or received under this Agreement. In the event that the Obligations are accelerated by reason of any election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the Maximum Rate and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the applicable Obligations (or, if the applicable Obligations shall have been paid in full, refunded to the Borrower). The provisions of this Section shall control over all other provisions of this Agreement or the other Credit Documents which may be in apparent conflict herewith.

Section 9.12 Confidentiality. None of the Administrative Agent, Issuing Lenders or Lenders shall disclose any Confidential Information to any Person without the consent of the Borrower, other than (a) to the Administrative Agent’s, Issuing Lender’s or Lender’s Affiliates and their officers, directors, employees, agents and advisors, (b) to actual or prospective Eligible Assignees and participants and their officers, directors, employees, agents and advisors, (c) to any direct, indirect, actual or prospective counterparty (and its advisor) to any swap, derivative or securitization transaction related to the obligations under this Agreement, and then, in any event, only on a confidential basis, (d) as required by any law, rule or regulation or judicial process, (e) as requested or required by any state, Federal or foreign authority or examiner (including the National Association of Insurance Commissioners or any similar organization or quasi-regulatory authority) regulating such Issuing Lender, such Lender or Administrative Agent, or to insurers, insurance brokers or direct or indirect providers of credit protection when required by it, provided that, prior to any such disclosure, such Person shall undertake to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from such Issuing Lender, such Lender or Administrative Agent, (f) to any rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from such Issuing Lender, such Lender or Administrative Agent, (g) in connection with any litigation or proceeding to which Administrative Agent, such Issuing Lender or such Lender or any of its Affiliates may be a party or (h) in connection with the exercise of any right or remedy under this Agreement or any other Credit Document. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, nothing in this Agreement shall (a) restrict the Administrative Agent, any Issuing Lender or any Lender from providing information to any bank or other regulatory or governmental authorities, including the Federal Reserve Board and its supervisory staff; (b) require or permit the Administrative Agent, any Issuing Lender or any Lender to disclose to the Borrower that any information will be or was provided to the Federal Reserve Board or any of its supervisory staff; or (c) require or permit the Administrative Agent, any Issuing Lender or any Lender to inform the Borrower of a current or upcoming Federal Reserve Board examination or any nonpublic Federal Reserve Board supervisory initiative or action.

(a) This Agreement, the Notes and the other Credit Documents shall be governed by, and construed and enforced in accordance with, the laws of the State of New York (including Section 5-1401 and Section 5-1402 of the General Obligations Law of the State of New York), without reference to any other conflicts or choice of law principles thereof.

(b) Any legal action or proceeding with respect to this Agreement or any other Credit Document may be brought in the courts of the state of New York sitting in New York City or of the United States for the Southern District of such state, and by execution and delivery of this Agreement, the Borrower, the Administrative Agent, each Issuing Lender, each Swingline Lender and each Lender consents, for itself and in respect of its property, to the non-exclusive jurisdiction of those courts. The Borrower, the Administrative Agent, each Issuing Lender, each Swingline Lender and each Lender irrevocably waives any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens, which it may now or hereafter have to the bringing of any action or proceeding in such jurisdiction in respect of this Agreement or any other Credit Document or other document related thereto.

(c) The Borrower irrevocably consents to the service of any and all process in any such action or proceeding by the mailing of copies of such process to it at the address specified for it in this Agreement.

(d) Nothing in this Section 9.13 shall affect the right of the Administrative Agent, any Issuing Lender, any Swingline Lender or any other Lender to serve legal process in any other manner permitted by law or affect the right of the Administrative Agent, any Issuing Lender, any Swingline Lender or any other Lender to bring any action or proceeding against the Borrower in the courts of any other jurisdiction.

Section 9.14 Waiver of Jury Trial. THE BORROWER, THE ISSUING LENDERS, THE SWINGLINE LENDERS, THE LENDERS AND THE ADMINISTRATIVE AGENT HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING, DIRECTLY OR INDIRECTLY (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE), ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER CREDIT DOCUMENT, ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY, OR THE RELATIONSHIP ESTABLISHED HEREUNDER.

Section 9.15 WAIVER OF CONSEQUENTIAL DAMAGES. TO THE EXTENT PERMITTED BY APPLICABLE LAW, BORROWER SHALL NOT ASSERT, AND THE BORROWER HEREBY WAIVES, ANY CLAIM AGAINST ANY OTHER PARTY HERETO AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS, ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES (AS OPPOSED TO DIRECT OR ACTUAL DAMAGES) ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF, THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT, ANY ADVANCE OR LETTER OF CREDIT OR THE USE OF THE PROCEEDS THEREOF.

Section 9.16 Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due from the Borrower hereunder in the currency expressed to be payable herein (the “specified currency”) into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with usual and customary banking procedures the Administrative Agent could purchase the specified currency with such other currency at any of the Administrative Agent’s offices in the United States of America on the Business Day preceding that on which final, non-appealable judgment is given. The obligations of the Borrower in respect of any sum due to any Lender, any Issuing Lender or the Administrative Agent hereunder shall, notwithstanding any judgment in a currency other than the specified currency, be discharged only to the extent that on the Business Day following receipt by such Lender, such Issuing Lender or the Administrative Agent (as the case may be) of any sum adjudged to be so due in such other currency such Lender, such Issuing Lender or the Administrative Agent (as the case may be) may in accordance with normal, reasonable banking procedures purchase the specified currency with such other currency. If the amount of the specified currency so purchased is less than the sum originally due to such

Lender, such Issuing Lender or the Administrative Agent, as the case may be, in the specified currency, the Borrower agrees, to the fullest extent that it may effectively do so, as a separate obligation and notwithstanding any such judgment, to indemnify such Lender, such Issuing Lender or the Administrative Agent, as the case may be, against such loss, and if the amount of the specified currency so purchased exceeds (a) the sum originally due to any Lender, such Issuing Lender or the Administrative Agent, as the case may be, in the specified currency and (b) any amounts shared with other Lenders as a result of allocations of such excess as a disproportionate payment to such Lender under Section 2.14, each Lender, Issuing Lender or the Administrative Agent, as the case may be, agrees to promptly remit such excess to the Borrower. All obligations of the Borrower provided in this Section 9.16 shall survive any termination of this Agreement and repayment in full of the Obligations.

Section 9.17 Headings Descriptive. The headings of the several Sections and paragraphs of the Agreement are inserted for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

Section 9.18 Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Acceptance shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

Section 9.19 USA Patriot Act. Each Lender that is subject to the Act (as hereinafter defined) and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Act.

This written agreement and the Credit Documents, as defined in this Agreement, represent the final agreement among the parties and may not be contradicted by evidence of prior, contemporaneous, or subsequent oral agreements of the parties.
