Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by (a) the Issuing Bank's failure to exercise care

when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof or (b) the Issuing Bank's gross negligence or willful misconduct. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented that appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g)Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed electronically or by telecopy) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to any such LC Disbursement.

(h)Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Revolving Loans; provided that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.12(c) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i)Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.11(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

(j)Cash Collateralization. If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives notice from the Administrative Agent or the Lenders holding at least fifty percent (50%) of the Commitments (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposure representing greater than 25% of the total LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an

amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand, notice of acceleration, notice of intent to accelerate or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (h) or (i) of ARTICLE VII. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the Obligations. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent consistent with the Administrative Agent's usual practices and at the Borrower's risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Exposure representing greater than 25% of the total LC Exposure), be applied to satisfy other Obligations. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived.

(k)Existing Letter of Credit. The Existing Letter of Credit will be considered a Letter of Credit under this Credit Agreement for all purposes.

(a)Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 2:00 p.m., Houston time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders; provided that Swingline Loans shall be made as provided in Section 2.04. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent in Houston and designated by the Borrower in the applicable Borrowing Request; provided that ABR Revolving Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.05(e) shall be remitted by the Administrative Agent to the Issuing Bank.

(b)Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender's share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to such Borrowing (without any obligation to pay any break funding payment under Section 2.15 in connection with such payment). If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender's Loan included in such Borrowing. If the Borrower pays such amount to the Administrative Agent, it shall not relieve the defaulting Lender of its legal responsibility for its default.

(a)Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. This Section shall not apply to Swingline Borrowings, which may not be converted or continued.

(b)To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Revolving Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by telecopy or email to the Administrative Agent of a written Interest Election Request signed by the Borrower in the form of the Interest Election Request attached hereto as Exhibit 2.07.

(c)Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02:

(i)the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing);

(ii)the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii)whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

(iv)if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

(d)Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender's portion of each resulting Borrowing.

(e)If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted

to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

(a)Unless previously terminated, the Commitments shall terminate on the Maturity Date.

(b)The Borrower may at any time terminate, or from time to time reduce, the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000 and (ii) the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Revolving Loans in accordance with Section 2.10, the Credit Exposure would exceed the total Commitments.

(c)The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable. Any termination or reduction of the Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments.

(a)The Borrower hereby unconditionally promises to pay (i) to the Administrative Agent for the account of each Lender the then‑unpaid principal amount of each Revolving Loan on the Maturity Date and (ii) to the Swingline Lender the then unpaid principal amount of each Swingline Loan on the Maturity Date; provided that on each date that a Revolving Borrowing is made, the Borrower shall repay all Swingline Loans then outstanding.

(b)Each Lender shall maintain in accordance with its usual practice a record evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(c)The Administrative Agent shall maintain records in which it shall record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender's share thereof.

(d)The entries made in the records maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

(e)Any Lender may request that Loans made by it be evidenced by a Note. In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns). Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

Section 2.10 Prepayment of Loans.

  

(a)The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with paragraph (b) of this Section, in each case without premium or penalty other than as specified in Section 2.15.

(b)The Borrower shall notify the Administrative Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender) by telephone (confirmed in writing) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 11:00 a.m., Houston time, three Business Days before the date of prepayment, (ii) in the case of prepayment of an ABR Revolving Borrowing, not later than 11:00 a.m., Houston time, one Business Day before the date of prepayment or (iii) in the case of prepayment of a Swingline Loan, not later than 12:00 noon, Houston time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid. Promptly following receipt of any such notice relating to a Revolving Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Revolving Borrowing shall be in an amount that would be permitted in the case of an advance of a Revolving Borrowing of the same Type as provided in Section 2.02 (other than prepayments required under paragraph (c)). Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.12.

(c)If at any time the total Credit Exposures exceed the Total Commitments, the Borrower shall (i) prepay Revolving Borrowings in an aggregate principal amount equal to such excess, and (ii) if any excess remains after prepaying all of the Revolving Borrowings as a result of LC Exposure, pay to the Administrative Agent on behalf of the Lender an amount equal to such excess to be held as cash collateral as provided in Section 2.05(j).

Section 2.11 Fees.

  

(a)The Borrower agrees to pay to the Administrative Agent for the account of each Lender an unused fee, which shall accrue at the Unused Fee Rate described in the definition of “Applicable Margin” on the daily unutilized amount of the Commitment of such Lender during the period from and including the Effective Date to but excluding the date on which such Commitment terminates. Accrued unused fees shall be payable in arrears on the last day of March, June, September and December of each year and on the date on which the Commitments terminate, commencing on the first such date to occur after the Effective Date. All unused fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). For the purposes of calculating the unused Commitment of each Lender, LC Exposure shall count as usage, but Swingline Loans made by the Swingline Lender shall not count as usage unless and until the Lenders have acquired participations therein as contemplated by Section 2.04(c).

(b)The Borrower agrees to pay (i) to the Administrative Agent for the account of

each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Margin used to determine the interest rate applicable to Eurodollar Revolving Loans on the average daily amount of such Lender's LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender's Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, as well as the Issuing Bank's standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable in arrears on the third Business Day following such last day, commencing on the first such date to occur after the Effective Date; provided that all such fees shall be payable on the date on which the Commitments terminate and any such fees accruing after the date on which the Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(c)The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent.

(d)All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the case of unused fees and participation fees, to the Lenders. Fees paid shall not be refundable under any circumstances.

Section 2.12 Interest.

(a)The Loans comprising each ABR Borrowing (including each Swingline Loan) shall bear interest at the Alternate Base Rate plus the Applicable Margin.

(b)The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin.

(c)Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2.0% plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section or (ii) in the case of any other amount, 2.0% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section.

(d)Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Commitments; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Revolving Loan prior to the end of the Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Revolving Loan prior

to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(e)All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

Section 2.13 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(i)the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(ii)the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Revolving Borrowing to, or continuation of any Revolving Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) any request for a new Eurodollar Borrowing shall be made as an ABR Borrowing.

Section 2.14 Increased Costs.

(a)If any Change in Law shall:

(i)impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or the Issuing Bank; or

(ii)impose on any Lender or the Issuing Bank or the London interbank market any other condition affecting this Agreement or Eurodollar Loans 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 of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender or the Issuing Bank of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or the Issuing Bank hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank, as the case may be, on an after‑tax basis for such additional costs incurred or reduction suffered.

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

(c)A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within ten (10) days after receipt thereof.

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

Section 2.15 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.18, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. Such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest that would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest that would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the Eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

Section 2.16 Taxes.

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

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

(c)The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error.

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

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

(f)If the Administrative Agent or a Lender determines, in its sole discretion, that it has received a refund of any Taxes or other amounts as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 2.16, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.16 with respect to the Taxes or other amounts giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This Section shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower

or any other Person.

(g)In the case of a Lender that would be subject to withholding tax imposed by FATCA on payments made on the account of any obligation of the Borrower hereunder if such Lender fails to comply with the applicable requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall provide 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 Administrative Agent or the Borrower as may be necessary for the Borrower to comply with its obligations under FATCA, to determine that such Lender has complied with such Lender's obligations under FATCA or to determine the amount to deduct and withhold from any such payments.

  

(a)The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.14, Section 2.15 or Section 2.16, or otherwise) prior to 12:00 noon, Houston time, on the date when due, in immediately available funds, without set off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at 712 Main Street, Houston, Texas, except payments to be made directly to the Issuing Bank or Swingline Lender as expressly provided herein and except that payments pursuant to Section 2.14, Section 2.15 or Section 2.16 and Section 9.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars.

(b)If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties.

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

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

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

(e)If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.04(c), Section 2.05(d), Section 2.05(e), Section 2.06(b), Section 2.17(d), or Section 9.03(c) then the Administrative Agent may, in its discretion and notwithstanding any contrary provision hereof, (i) apply any amounts thereafter received by the Administrative Agent for the account of such Lender and for the benefit of the Administrative Agent, the Swingline Lender or the Issuing Bank to satisfy such Lender's obligations under such Sections until all such unsatisfied obligations are fully paid, and/or (ii) hold any such amounts in a segregated account as cash collateral for, and application to, any future funding obligations of such Lender under such Sections; in the case of each of (i) and (ii) above, in any order as determined by the Administrative Agent in its discretion.

Section 2.18 Mitigation Obligations; Replacement of Lenders.

  

(a)If any Lender requests compensation under Section 2.14, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.16, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans 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 2.14 or Section 2.16, 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 designation or assignment.

(b)If any Lender requests compensation under Section 2.14, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.16, or if any Lender becomes a Defaulting Lender, or any Lender refuses to consent to an amendment, modification or waiver of this Agreement that requires consent of 100% of Lenders pursuant to Section 9.02 hereof, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse

(in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) if the proposed assignee is not at such time a Lender, the Borrower shall have received the prior written consent of the Administrative Agent (and, if a Commitment is being assigned, the Issuing Bank), which consent shall not unreasonably be withheld, delayed or conditioned, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements and Swingline Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.14 or payments required to be made pursuant to Section 2.16, such assignment will result in a reduction in such compensation or payments in the future. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

Section 2.19 Increase in the Commitments.

(a)If no Default shall have occurred and be continuing, the Borrower may at any time during the Availability Period request one or more increases of the Commitments by notice to the Administrative Agent in writing of the amount of such proposed increase (such notice, a “Commitment Increase Notice”); provided, however, that (i) the Commitment of any Lender may not be increased without such Lender's consent, (ii) the minimum amount of any such increase shall be $10,000,000 and (iii) the aggregate amount of the Lenders' Commitments, after giving effect to any such increase, shall not exceed $400,000,000.

(b)Following any Commitment Increase Notice, the Borrower may, in its sole discretion, but with the consent of the Administrative Agent as to any Person that is not at such time a Lender (which consent shall not be unreasonably withheld, delayed or conditioned), offer to any existing Lender or to one or more additional banks or financial institutions the opportunity to participate in all or a portion of the increased Commitments pursuant to paragraph (c) or (d) below, as applicable, by notifying the Administrative Agent. Promptly and in any event within five (5) Business Days after receipt of notice from the Borrower of its desire to offer such unsubscribed commitments to certain existing Lenders, to the additional banks or financial institutions identified therein or to such existing Lenders, additional banks or financial institutions as may be identified by the Administrative Agent and approved by the Borrower, the Administrative Agent shall notify such proposed lenders of the opportunity to participate in all or a portion of such unsubscribed portion of the increased Commitments.

(c)Any additional bank or financial institution that the Borrower selects to offer participation in the increased Commitments shall notify the Administrative Agent of its agreement to participate in the increased Commitments within five (5) Business Days of the date the Administrative Agent's notice described in (b) above is sent and shall execute and deliver to the Administrative Agent a New Lender Agreement setting forth its Commitment, and upon the effectiveness of such New Lender Agreement such bank or financial institution (a “New Lender”) shall become a Lender for all purposes and to the same extent as if originally a party hereto and shall be bound by and entitled to the benefits of this Agreement, and the signature pages hereof shall be deemed to be amended to add the name of such New Lender and Schedule 2.01 and the definition of Commitment in Section 1.01 hereof shall be deemed amended to increase the aggregate Commitments of the Lenders by the Commitment of such New Lender, provided that the Commitment of any New Lender shall be an amount not less than $10,000,000. Each New Lender Agreement shall be irrevocable and shall be effective upon notice thereof by the Administrative Agent at the same time as that of all other New Lenders or increasing Lenders.

(d)Any Lender that accepts an offer to it by the Borrower to increase its Commitment pursuant to this Section 2.19 shall, in each case, execute a Commitment Increase Agreement with the Borrower and the Administrative Agent, whereupon such Lender shall be bound by and entitled to the benefits of this Agreement with respect to the full amount of its Commitment as so increased, and Schedule 2.01 and the definition of Commitment in Section 1.01 hereof shall be deemed to be amended to reflect such increase. Any Commitment Increase Agreement shall be irrevocable and shall be effective upon notice thereof by the Administrative Agent at the same time as that of all other New Lenders and increasing Lenders.

(e)The effectiveness of any New Lender Agreement or Commitment Increase Agreement shall be contingent upon receipt by the Administrative Agent of corporate resolutions of the Borrower authorizing such increase. Once a New Lender Agreement or Commitment Increase Agreement becomes effective, the Administrative Agent shall reflect the increases in the Commitments effected by such agreements by appropriate entries in the Register.

(f)If any bank or financial institution becomes a New Lender pursuant to Section 2.19(c) or any Lender's Commitment is increased pursuant to Section 2.19(d), additional Loans made on or after the effectiveness thereof (the “Re-Allocation Date”) shall be made pro rata based on their respective Commitments in effect on or after such Re-Allocation Date (except to the extent that any such pro rata borrowings would result in any Lender making an aggregate principal amount of Loans in excess of its Commitment, in which case such excess amount will be allocated to, and made by, such New Lender and/or Lenders with such increased Commitments to the extent of, and pro rata based on, their respective Commitments), and continuations of Loans outstanding on such Re-Allocation Date shall be effected by repayment of such Loans on the last day of the Interest Period applicable thereto or, in the case of ABR Loan, on the date of such increase, and the making of new Loans of the same Type pro rata based on the respective Commitments in effect on and after such Re-Allocation Date.

(g)If on any Re-Allocation Date there is an unpaid principal amount of Eurodollar Loans, such Eurodollar Loans shall remain outstanding with the respective holders thereof until the expiration of their respective Interest Periods (unless the Borrower elects to prepay any thereof in accordance with the applicable provisions of this Agreement), and interest on and repayments of such Eurodollar Loans will be paid thereon to the respective Lenders holding such Eurodollar Loans pro rata based on the respective principal amounts thereof outstanding.

(h)Upon the effectiveness of any Commitment Increase Agreement, Schedule 2.01 and other pertinent sections hereof shall be automatically and proportionately modified to reflect the increased Commitment, the exact figures to be agreed between the Borrower and the Administrative Agent, and all references to the Commitments shall be deemed amended mutatis mutandis.

Section 2.20 Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(a)fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender pursuant to Section 2.11(a);

(b)the Commitment and Credit Exposure of such Defaulting Lender shall not be included in determining whether all Lenders or the Required Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 9.02), provided that any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender which

affects such Defaulting Lender differently than other affected Lenders shall require the consent of such Defaulting Lender, unless the effect of same is to eliminate the Defaulting Lender's Commitment (which shall require only the consent of the Lenders that are not Defaulting Lenders);

(c)if any Swingline Exposure or LC Exposure exists at the time a Lender becomes a Defaulting Lender then:

(i)all or any part of such Swingline Exposure and LC Exposure shall be reallocated among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but only to the extent (x) the sum of all non-Defaulting Lenders' Credit Exposures plus such Defaulting Lender's Swingline Exposure and LC Exposure does not exceed the total of all non-Defaulting Lenders' Commitments and (y) the conditions set forth in Section 4.02 are satisfied at such time;

(ii)if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within one Business Day following notice by the Administrative Agent (x) first, prepay such Swingline Exposure and (y) second, cash collateralize such Defaulting Lender's LC Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.05(j) for so long as such LC Exposure is outstanding;

(iii)if the Borrower cash collateralizes any portion of such Defaulting Lender's LC Exposure pursuant to Section 2.20(c), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.11(b) with respect to such Defaulting Lender's LC Exposure during the period such Defaulting Lender's LC Exposure is cash collateralized;

(iv)if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to Section 2.20(c), then the fees payable to the Lenders pursuant to Section 2.11(a) and Section 2.11(b) shall be adjusted in accordance with such non-Defaulting Lenders' Applicable Percentages; and

(v)if any Defaulting Lender's LC Exposure is neither cash collateralized nor reallocated pursuant to Section 2.20(c), then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, all facility fees that otherwise would have been payable to such Defaulting Lender (solely with respect to the portion of such Defaulting Lender's Commitment that was utilized by such LC Exposure) and letter of credit fees payable under Section 2.11(b) with respect to such Defaulting Lender's LC Exposure shall be payable to the Issuing Bank until such LC Exposure is cash collateralized and/or reallocated; and

(d)so long as any Lender is a Defaulting Lender, the Swingline Lender shall not be required to fund any Swingline Loan and the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless it is reasonably satisfied that the related exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 2.20(c), and participating interests in any such newly issued or increased Letter of Credit or newly made Swingline Loan shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.20(c)(i) (and Defaulting Lenders shall not participate therein).

In the event that the Administrative Agent, the Borrower, the Issuing Bank and the Swingline Lender each agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the Swingline Exposure and LC Exposure of the Lenders

shall be readjusted to reflect the inclusion of such Lender's Commitment and on such date such Lender shall purchase at par such of the Loans of the other Lenders (other than Swingline Loans) as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Applicable Percentage.

The Borrower represents and warrants to the Lenders that:

Section 3.01 Organization; Powers.

(k)one or more judgments for the payment of money in an aggregate amount in excess of $15,000,000 shall be rendered against the Borrower, any Subsidiary or any combination thereof and the same shall remain undischarged for a period of 30 consecutive days during which execution shall not be effectively stayed, or any action shall be legally taken by a judgment creditor to attach or levy upon any assets of the Borrower or any Subsidiary to enforce any such judgment;

(l)an ERISA Event shall have occurred that when taken together with all other ERISA Events that have occurred or are continuing, could reasonably be expected to result in a Material Adverse Effect; or

(m)a Change in Control shall occur;

then, and in every such event (other than an event with respect to the Borrower described in clause (h) or (i) of this Article), and at any time thereafter during the continuance of such event, the Administrative Agent may, and at the request of the Required Lenders shall, by notice to the Borrower, take either or both of the following actions, at the same or different times: (i) terminate the Commitments, and thereupon the Commitments shall terminate immediately, and (ii) declare the Loans then outstanding to be due and payable in whole (or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of the Loans so declared to be due and payable, together with accrued interest thereon and all fees and other obligations of the Borrower accrued hereunder, shall become due and payable immediately, without presentment, demand, protest, notice of acceleration, notice of intent to accelerate or other notice of any kind, all of which are hereby waived by the Borrower; and in case of any event with respect to the Borrower described in clause (h) or (i) of this Article, the Commitments shall automatically terminate and the principal of the Loans then outstanding, together with accrued interest thereon and all fees and other obligations of the Borrower accrued hereunder, shall automatically become due and payable, without presentment, demand, protest, notice of acceleration, notice of intent to accelerate or other notice of any kind, all of which are hereby waived by the Borrower, and (iii) take such other steps to collect the Loans and protect the interest of the Lenders as shall be allowed by law or in equity.

Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto.

The bank serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not the Administrative Agent hereunder.

The Administrative Agent shall not have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise

any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing as directed by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of the Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in ARTICLE IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrower. Upon any such resignation, the Required Lenders shall have the right, with, if no Default is then continuing, the consent of the Borrower (not to be unreasonably withheld, delayed or conditioned), to appoint a successor. If no successor shall have been so appointed by the Required Lenders (and, if applicable, consented to by the Borrower) and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which shall be a bank with an office in Houston, Texas, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall

be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent's resignation hereunder, the provisions of this Article and Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such 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 or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder.

(c)Any party hereto may change its address or telecopy number for notices and other communications hereunder by notice to the other parties hereto. All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have

Section 9.02 Waivers; Amendments; Release of Guarantors.

 

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

(b)Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender adversely affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.17(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) release any Guarantor or release all or substantially all of the collateral for the Loans without the consent of each Lender (other than Defaulting Lenders), (vi) change any provisions of Section 2.20 or the definition of “Defaulting Lender” without the consent of each Lender, or (vii) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, the Issuing Bank or the Swingline Lender hereunder without the prior written consent of the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case may be.

(c)Notwithstanding any contrary position in this Agreement or any other Loan Document, if (a) a Guarantor is no longer a Subsidiary and (b) at the time such Guarantor became a non-Subsidiary, no Event of Default then existed, then such Guarantor shall be automatically released from its obligations under the Guarantee Agreement to which it is a party, without need for any formal action by the Administrative Agent or any Lender; and the Administrative Agent will confirm such release by a notice to the Borrower upon receipt of a request therefor.

Section 9.03 Expenses; Indemnity; Damage Waiver.

  

(a)The Borrower shall pay (i) all reasonable out of pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein,

the preparation and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or in connection with the Loans made or Letters of Credit issued hereunder, including all such out-of pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

(b)The Borrower shall indemnify the Administrative Agent, the Issuing Bank and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee but, with respect to the expenses, fees, charges and disbursements described in subparagraphs (a)(i) and (a)(ii) of this Section, only to the extent reasonable, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (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 the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any Subsidiary, or any Environmental Liability related in any way to the Borrower or any Subsidiary, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee.

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

(d)To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, 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 agreement or instrument contemplated hereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

(e)All amounts due under this Section shall be payable promptly after written demand therefor.

(f)The indemnification and reimbursement provisions contained herein with respect to fees of counsel shall be limited to one counsel for all Indemnitees, unless a conflict of interest exists among Indemnitees in which case each Indemnitee affected by such conflict of interest shall have separate counsel, the fees of which shall be reimbursed by the Borrower (except to the extent resulting from the gross negligence or willful misconduct of an Indemnitee.

WITHOUT LIMITING ANY PROVISION OF THIS AGREEMENT, IT IS THE EXPRESS INTENTION OF THE PARTIES HERETO THAT EACH PERSON TO BE INDEMNIFIED HEREUNDER SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES, CLAIMS AND DAMAGES ARISING OUT OF OR RESULTING FROM THE ORDINARY, SOLE AND CONTRIBUTORY NEGLIGENCE OF SUCH PERSON.

Section 9.04 Successors and Assigns.

(a)The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b)(i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld, delayed or conditioned) of:

(A)the Borrower, provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender or, if an Event of Default has occurred and is continuing, any other assignee, provided further that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five Business Days after having received written notice thereof;

(B)the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment to an assignee that is a Lender or an Affiliate of a Lender; and

(C)the Issuing Bank and Swingline Lender.

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

(A)except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender's Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment

(determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $10,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default under clause (a), (b), (h) or (i) of ARTICLE VII has occurred and is continuing;

(B)each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender's rights and obligations under this Agreement;

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

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

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement other than Section 9.12 (and, in the case of an Assignment and Assumption covering all of the assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 2.14, Section 2.15, Section 2.16 and Section 9.03; provided that such release shall not affect any legal responsibility for such Lender's actions and failures to act occurring before the effective date of such Assignment and Assumption). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

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

(vi) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee's completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant

to Section 2.04(c), Section 2.05(d), Section 2.05(e), Section 2.06(b), Section 2.17(d), or Section 9.03(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c)(i) Any Lender may, without the consent of the Borrower, the Administrative Agent, the Issuing Bank or the Swingline Lender, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender's rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender's obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (C) the Borrower, the Administrative Agent, the Issuing Bank 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 and (D) by its acceptance of such participation, such Participant shall be deemed to have consented to be bound by Section 9.12. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Section 2.14, Section 2.15 and Section 2.16 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.17(c) as though it were a Lender.

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

(d)Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Section 9.05 Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall

continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Section 2.14, Section 2.15, Section 2.16, Section 9.03, Section 9.12 and ARTICLE VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof.

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

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

Section 9.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, but excluding deposits held in a fiduciary capacity for a third party) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured; provided that any Lender or Affiliate thereof exercising rights under this Section shall use commercially reasonable efforts to notify the Borrower promptly after exercising such rights; provided, further that the failure to give such notice shall not affect such exercise of rights or any other rights of the Lenders and their Affiliates under this Section. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

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

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

(b)The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the District Courts of the State of Texas sitting in Houston, Harris County, Texas and of the United States District Court of the Southern District of Texas, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and

unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such Texas State or, to the extent permitted by law, in such Federal court.

(c)Each party hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

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

THIS GUARANTEE AGREEMENT (this “Guarantee”) dated as of September 23, 2011, made by each of the undersigned Subsidiaries of the Borrower (as defined below) (each, a “Guarantor,” and collectively, the “Guarantors”), in favor of JPMorgan Chase Bank, N.A. as Administrative Agent (the “Agent”) for the benefit of the Lenders pursuant to that certain Revolving Credit Agreement dated as of even date herewith (as amended, modified and supplemented from time to time, the “Credit Agreement”), by and among the Borrower, the Agent and the Lenders.

WHEREAS, pursuant to the Credit Agreement, the Lenders have agreed to make Loans and other extensions of credit to Rackspace Hosting, Inc., a Delaware corporation (the “Borrower”) in a manner and upon the terms and conditions set forth therein;

WHEREAS, in accordance with the Credit Agreement, the Agent requires that the Guarantors execute a guarantee agreement guaranteeing the obligations of the Borrower under the Credit Agreement;

NOW, THEREFORE, in consideration of the premises and agreements herein and in order to induce the Lenders to make the Loans and other extensions of credit pursuant to the Credit Agreement, the Guarantors hereby agree as follows:

Section 1.    Definitions. Capitalized terms used herein and not otherwise defined shall have the respective meanings assigned thereto in the Credit Agreement.

Section 2.    Guarantee of Payment. Each Guarantor (not merely as a surety or guarantor of collection) hereby jointly, severally, unconditionally and irrevocably, guarantees the punctual payment and performance when due, whether at stated maturity, as an installment, by prepayment or by demand, acceleration or otherwise, of all Obligations of the Borrower heretofore or hereafter existing. If any or all of the Obligations become due and payable under the Credit Agreement, the Guarantors jointly and severally and unconditionally promise to pay such Obligations, on demand, together with any and all expenses (including reasonable counsel fees and expenses), which may be incurred by the Agent in collecting any of the Obligations and in connection with the protection, defense and enforcement of any rights under the Credit Agreement or under any other Loan Document (the “Expenses”). The Guarantors guarantee that the Obligations shall be paid strictly in accordance with the terms of the Credit Agreement. The Obligations include, without limitation, interest accruing after the commencement of a proceeding under bankruptcy, insolvency or similar laws of any jurisdiction at the rate or rates provided in the Credit Agreement. The Agent shall not be required to exhaust any right or remedy or take any action against the Borrower or any other Person or any collateral prior to any demand or other action hereunder against the Guarantors. The Guarantors agree that, as between the Guarantors and the Agent, the Obligations may be declared to be due and payable for the purposes of this Guarantee at any time when the Loans may be declared due under Article VII of the Credit Agreement, notwithstanding any stay, injunction or other prohibition which may prevent, delay or vitiate any declaration as regards the Borrower and that in the event of a declaration or attempted declaration, the Obligations shall immediately become due and payable by the Guarantors for the purposes of this Guarantee and each Guarantor shall forthwith pay the Obligations specified by the Agent to be paid as provided in the Credit Agreement without further notice or demand. Notwithstanding anything contained herein or in the Credit Agreement, any Loan Document or any other document or any other agreement, security document or instrument relating hereto or thereto to the contrary, the maximum liability of each Guarantor hereunder shall never exceed the maximum amount that said Guarantor could pay without having such payment set aside as a fraudulent transfer or fraudulent conveyance or similar action under the U.S. Bankruptcy Code or applicable state or foreign law.

Section 3.    Guarantee Absolute. The liability of each Guarantor under this Guarantee is absolute and unconditional irrespective of: (a) any change in the time, manner or place of payment of, or in any other term of, the

Credit Agreement or the Obligations, or any other amendment or waiver of or any consent to departure from any of the terms of the Credit Agreement or the Obligations, including any increase or decrease in the rate of interest thereon; (b) any release or amendment or waiver of, or consent to departure from, any other guarantee or support document, or any exchange, release or non‑perfection of any collateral, for the Credit Agreement or the Obligations; (c) any present or future law, regulation or order of any jurisdiction or of any agency thereof purporting to reduce, amend, restructure or otherwise affect any term of the Credit Agreement or the Obligations; (d) without being limited by the foregoing, any lack of validity or enforceability of the Credit Agreement or the Obligations; (e) any other setoff, defense or counterclaim whatsoever (in any case, whether based on contract, tort or any other theory) with respect to the Credit Agreement or the transactions contemplated thereby which might constitute a legal or equitable defense available to, or discharge of, the Borrower or other Guarantors and (f) any claim or assertion that any payment by any Guarantor hereunder should be set aside pursuant to Section 2 in connection with any stay, injunction or other prohibition or event, in which case each Guarantor shall be unconditionally required to pay all amounts demanded of it hereunder prior to any determination of the maximum liability of each Guarantor hereunder in accordance with Section 2 and the recipient of such payment, if so required by a final non-appealable court of competent jurisdiction by a final and non-appealable judgment, shall then be liable for the refund of any excess amounts. If any such rebate or refund is ever required, all other Guarantors shall be fully liable for the repayment thereof to the maximum extent allowed by applicable law.

Section 4.    Guarantee Irrevocable. This Guarantee is a continuing guarantee of the payment of all Obligations now or hereafter existing under the Credit Agreement and shall remain in full force and effect until payment in full of all Obligations and other amounts payable under this Guarantee and until all Commitments of the Lenders to make Loans under the Credit Agreement shall be terminated in accordance with the terms thereof and the Credit Agreement is no longer in effect.

Section 5.    Reinstatement. This Guarantee shall continue to be effective, or be automatically reinstated, as the case may be, if at any time any payment of any of the Obligations is rescinded or must otherwise be returned by the Agent on the insolvency, bankruptcy, dissolution, liquidation or reorganization of any of the Borrower, any Guarantor, or any Person that is a party to the Loan Documents, or upon or as a result of the appointment of a custodian, receiver, trustee or other officer with similar powers with respect to any of the Borrower, any Guarantor or any other Person that is a party to the Loan Documents, or otherwise, all as though the payment had not been made.

Section 6.    Subrogation. Each Guarantor hereby agrees that it shall not exercise any rights which it may acquire by way of subrogation, by any payment made under this Guarantee or otherwise, until all the Obligations have been paid in full and the Credit Agreement is no longer in effect. Any amounts paid to a Guarantor on account of subrogation rights under this Guarantee at any time when all the Obligations have not been paid in full, shall be held in trust for the benefit of the Agent and shall promptly be paid to the Agent to be credited and applied to the Obligations, whether matured or unmatured or absolute or contingent, in accordance with the terms of the Credit Agreement. If a Guarantor has made a payment to the Agent hereunder of all or any part of the Obligations and all the Obligations are paid in full (other than unasserted indemnity obligations) and the Commitments have been terminated, the Agent shall, at such Guarantor's request, execute and deliver to the Guarantor the appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to the Guarantor of an interest in the Obligations resulting from the payment.

Section 7.    Subordination. Any liabilities owed by the Borrower to the Guarantors in connection with any extension of credit or financial accommodation by the Guarantors to or for the account of the Borrower, including but not limited to interest accruing at the agreed contract rate after the commencement of a bankruptcy or similar proceeding, are hereby subordinated to the Obligations, and such liabilities of the Borrower to the Guarantors, if the Agent so requests, shall be collected, enforced and received by the Guarantors as trustee for the Agent and shall be paid over to the Agent on account of the Obligations.

Section 8.    Certain Taxes. The Guarantors further agree that all payments to be made hereunder shall be made without setoff or counterclaim and free and clear of, and without deduction for Indemnified Taxes or Other Taxes. If any Indemnified Taxes or Other Taxes are required to be withheld from any amounts payable to the Agent hereunder, the amounts so payable to the Agent shall be increased to the extent necessary to yield to the Agent (after payment of

all Indemnified Taxes or Other Taxes) the amounts payable hereunder in the full amounts so to be paid. Whenever any Indemnified Tax or Other Tax is paid by a Guarantor, as promptly as possible thereafter, such Guarantor shall send the Agent evidence of payment thereof, together with such additional documentary evidence as may be reasonably required from time to time by the Agent.

Section 9.    Representations and Warranties. Each of the Guarantors represents and warrants that: (a) this Guarantee (i) has been authorized by all necessary action; (ii) does not violate any agreement, instrument, law, regulation or order applicable to it; (iii) does not require the consent or approval of any Person, or any filing or registration of any kind; and (iv) is the legal, valid and binding obligation of such Guarantor enforceable against such Guarantor in accordance with its terms, except to the extent that enforcement may be limited by applicable bankruptcy, insolvency and other similar laws affecting creditors' rights generally; and (b) in executing and delivering this Guarantee, such Guarantor has not relied and will not rely upon any representations or warranties of the Agent not embodied herein or any acts heretofore or hereafter taken by the Agent (including but not limited to any review by the Agent of the affairs of the Borrower).

Section 12.    Formalities. Each Guarantor hereby waives promptness, diligence, notice of acceptance and any other notice with respect to any of the Obligations, the Credit Agreement and this Guarantee and any liability to which the Credit Agreement and this Guarantee applies or may apply, and waives presentment, demand of payment, notice of intent to accelerate, notice of acceleration, notice of dishonor or nonpayment, and any requirement that the Agent institute suit, collection proceedings or take any other action to collect the Obligations, including any requirement that the Agent protect, secure, perfect or insure any security interest or Lien against any property subject thereto or exhaust any right or take any action against the Borrower or any other Person (including the other Guarantors) or any collateral (it being the intention of the Agent and each Guarantor that the obligations of such Guarantor under this Guarantee are to be a guarantee of payment and not of collection) or that the Borrower or any other Person (including the other Guarantors) be joined in any action hereunder. Each Guarantor hereby waives marshaling of assets and liabilities, notice by the Agent of the creation of any Indebtedness or liability to which it applies or may apply, notice of disposition or substitution of collateral and of the creation, advancement, increase, existence, extension, renewal, rearrangement and/or modification of the Obligations.
