(b) The Administrative Agent shall give to each Lender prompt notice of the Administrative Agent’s receipt of a Notice of Borrowing and, if Eurodollar Rate Loans are properly requested in such Notice of Borrowing, the applicable interest rate determined pursuant to 2.13(a) (Determination of Interest Rate). Each Lender shall, (x) before 2:00 p.m. (New York time) on the date of the proposed Borrowing of Base Rate Loans and (y) before 11:00 a.m. (New York time) on the date of the

proposed Borrowing of Eurodollar Rate Loans, make available to the Administrative Agent at its address referred to in Section 10.8 (Notices), in immediately available funds, such Lender’s Ratable Portion of such proposed Borrowing. Upon fulfillment (or due waiver in accordance with Section 10.1) (i) on the Closing Date, of the applicable conditions set forth in Section 4.1 (Conditions to Effectiveness) and (ii) at any time (including the Closing Date), of the applicable conditions set forth in Section 4.2 (Conditions Precedent to Each Extension of Credit), and after the Administrative Agent’s receipt of such funds, the Administrative Agent shall make such funds available to the Borrower.

(c) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any proposed Borrowing that such Lender will not make available to the Administrative Agent such Lender’s Ratable Portion of such Borrowing (or any portion thereof), the Administrative Agent may assume that such Lender has made such Ratable Portion available to the Administrative Agent on the date of such Borrowing in accordance with this Section 2.2 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such Ratable Portion available to the Administrative Agent, such Lender and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to the Loans comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate for the first Business Day and thereafter at the interest rate applicable at the time to the Loans comprising such Borrowing. If such Lender shall repay to the Administrative Agent such corresponding amount, such corresponding amount so repaid shall constitute such Lender’s Loan as part of such Borrowing for purposes of this Agreement. If the Borrower shall repay to the Administrative Agent such corresponding amount, such payment shall not relieve such Lender of any obligation it may have hereunder to the Borrower.

(d) The failure of any Lender to make on the date specified any Loan or any payment required by it (such Lender being a “Non-Funding Lender”), including any payment in respect of its participation in Letter of Credit Obligations, shall not relieve any other Lender of its obligations to make such Loan or payment on such date but no such other Lender shall be responsible for the failure of any Non-Funding Lender to make a Loan or payment required under this Agreement.

None of the Lenders (other than the Issuers in their capacity as such) shall have any obligation to Issue any Letter of Credit.

(b) In no event shall the expiration date of any Letter of Credit (i) be more than one year after the date of issuance thereof or (ii) be less than five days prior to the Scheduled Termination Date; provided, however, that any Letter of Credit with a term less than or equal to one year may provide for the renewal thereof for additional periods less than or equal to one year, as long as (x) on or before the expiration of each such term and each such period, the Borrower and the Issuer of such Letter or Credit shall have the option to prevent such renewal and (y) neither the Issuer of such Letter of Credit nor the Borrower shall permit any such renewal to extend the expiration date of any Letter beyond the date set forth in clause (ii) above.

(c) In connection with the Issuance of each Letter of Credit, the Borrower shall give the relevant Issuer and the Administrative Agent at least two Business Days’ prior written notice, in substantially the form of Exhibit H (Form of Letter of Credit Request) (or in such other written or electronic form as is acceptable to the Issuer), of the requested Issuance of such Letter of Credit (a “Letter of Credit Request”). Such notice shall be irrevocable and shall specify the Issuer of such Letter of Credit and face amount of the Letter of Credit requested (which shall not be less than $1,000,000), the date of Issuance of such requested Letter of Credit, the date on which such Letter of Credit is to expire (which date shall be a Business Day) and, in the case of an issuance, the Person for whose benefit the requested Letter of Credit is to be issued. Such notice, to be effective, must be received by the relevant Issuer and the Administrative Agent not later than 11:00 a.m. (New York time) on the second Business Day prior to the requested Issuance of such Letter of Credit.

(d) Subject to the satisfaction of the conditions set forth in this Section 2.3, the relevant Issuer shall, on the requested date, Issue a Letter of Credit on behalf of the Borrower in accordance with such Issuer’s usual and customary business practices. No Issuer shall Issue any Letter of Credit in the period commencing on the first Business Day after it receives written notice from any Lender that one or more of the conditions precedent contained in Section 4.2 (Conditions Precedent to Each Extension of Credit) or clause (a) above (other than those conditions set forth in clauses (a)(i), (a)(vi)(B) and (C) above and, to the extent such clause relates to fees owing to the Issuer of such Letter of Credit and its Affiliates, clause (a)(vi)(A) above) are not on such date satisfied or duly waived and ending when such conditions are satisfied or duly waived. No Issuer shall otherwise be required to determine that, or take notice whether, the conditions precedent set forth in Section 4.2 (Conditions Precedent to Each Extension of Credit) have been satisfied in connection with the Issuance of any Letter of Credit.

(e) The Borrower agrees that, if requested by the Issuer of any Letter of Credit, it shall execute a Letter of Credit Reimbursement Agreement in respect to any Letter of Credit Issued hereunder. In the event of any conflict between the terms of any Letter of Credit Reimbursement Agreement and this Agreement or to the extent any Letter of Credit Reimbursement Agreement purports to add defaults or events of default or provide for the grant of security not contemplated by this Agreement, the terms of this Agreement shall govern.

(i) give the Administrative Agent written notice (or telephonic notice confirmed promptly thereafter in writing), which writing may be a telecopy or electronic mail, of the Issuance of any Letter of Credit Issued by it, of all drawings under any Letter of Credit Issued by it and of the payment (or the failure to pay when due) by the Borrower of any Reimbursement Obligation when due (which notice the Administrative Agent shall promptly transmit by telecopy, electronic mail or similar transmission to each Lender);

(ii) upon the request of any Lender, furnish to such Lender copies of any Letter of Credit Reimbursement Agreement to which such Issuer is a party and such other documentation as may reasonably be requested by such Lender; and

(iii) no later than 10 Business Days following the last day of each calendar month, provide to the Administrative Agent (and the Administrative Agent shall provide a copy to each Lender requesting the same) and the Borrower a schedule of Letters of Credit issued by it, in form and substance reasonably satisfactory to the Administrative Agent, setting forth the aggregate Letter of Credit Obligations, in each case outstanding at the end of each month, and any information requested by the Borrower or the Administrative Agent relating thereto.

(g) Immediately upon the issuance by an Issuer of a Letter of Credit in accordance with the terms and conditions of this Agreement, such Issuer shall be deemed to have sold and transferred to each Lender, and each Lender shall be deemed irrevocably and unconditionally to have purchased and received from such Issuer, without recourse or warranty, an undivided interest and participation, to the extent of such Lender’s Ratable Portion, in such Letter of Credit and the obligations of the Borrower with respect thereto (including all Letter of Credit Obligations with respect thereto) and any security therefor and guaranty pertaining thereto.

(h) The Borrower agrees to pay to the Issuer of any Letter of Credit the amount of all Reimbursement Obligations owing to such Issuer under any Letter of Credit issued for its account no later than the date that is the next succeeding Business Day after the Borrower receives written notice from such Issuer that payment has been made under such Letter of Credit (the “Reimbursement Date”),

irrespective of any claim, set-off, defense or other right that the Borrower may have at any time against such Issuer or any other Person. In the event that any Issuer makes any payment under any Letter of Credit and the Borrower shall not have repaid such amount to such Issuer pursuant to this clause (h) or any such payment by the Borrower is rescinded or set aside for any reason, such Reimbursement Obligation shall be payable on demand with interest thereon computed (i) from the date on which such Reimbursement Obligation arose to the Reimbursement Date, at the rate of interest applicable during such period to Revolving Loans that are Base Rate Loans and (ii) from the Reimbursement Date until the date of repayment in full, at the rate of interest applicable during such period to past due Revolving Loans that are Base Rate Loans, and such Issuer shall promptly notify the Administrative Agent, which shall promptly notify each Lender of such failure, and each Lender shall promptly and unconditionally pay to the Administrative Agent for the account of such Issuer the amount of such Lender’s Ratable Portion of such payment in immediately available Dollars. If the Administrative Agent so notifies such Lender prior to 11:00 a.m. (New York time) on any Business Day, such Lender shall make available to the Administrative Agent for the account of such Issuer its Ratable Portion of the amount of such payment on such Business Day in immediately available funds. Upon such payment by a Lender, such Lender shall, except during the continuance of a Default or Event of Default under Section 8.1(f) (Events of Default) and notwithstanding whether or not the conditions precedent set forth in Section 4.2 (Conditions Precedent to Each Extension of Credit) shall have been satisfied (which conditions precedent the Lenders hereby irrevocably waive), be deemed to have made a Revolving Loan to the Borrower in the principal amount of such payment. Whenever any Issuer receives from the Borrower a payment of a Reimbursement Obligation as to which the Administrative Agent has received for the account of such Issuer any payment from a Lender pursuant to this clause (h), such Issuer shall pay over to the Administrative Agent any amount received in excess of such Reimbursement Obligation and, upon receipt of such amount, the Administrative Agent shall promptly pay over to each Lender, in immediately available funds, an amount equal to such Revolving Credit Lender’s Ratable Portion of the amount of such payment adjusted, if necessary, to reflect the respective amounts the Revolving Credit Lenders have paid in respect of such Reimbursement Obligation.

(i) If and to the extent such Lender shall not have so made its Ratable Portion of the amount of the payment required by clause (h) above available to the Administrative Agent for the account of such Issuer, such Lender agrees to pay to the Administrative Agent for the account of such Issuer forthwith on demand any such unpaid amount together with interest thereon, for the first Business Day after payment was first due at the Federal Funds Rate and, thereafter, until such amount is repaid to the Administrative Agent for the account of such Issuer, at a rate per annum equal to the rate applicable to Base Rate Loans under the Facility.

(j) The Borrower’s obligation to pay each Reimbursement Obligation and the obligations of the Lenders to make payments to the Administrative Agent for the account of the Issuers with respect to Letters of Credit shall be absolute, unconditional and irrevocable and shall be performed strictly in accordance with the terms of this Agreement, under any and all circumstances whatsoever, including the occurrence of any Default or Event of Default, and irrespective of any of the following:

(i) any lack of validity or enforceability of any Letter of Credit or any Loan Document, or any term or provision therein;

(ii) any amendment or waiver of or any consent to departure from all or any of the provisions of any Letter of Credit or any Loan Document;

(iii) the existence of any claim, set off, defense or other right that the Borrower, any other Loan Party, any other party guaranteeing, or otherwise obligated with, the Borrower, any Subsidiary of a Loan Party or other Affiliate thereof or any other Person may at any time have

against the beneficiary under any Letter of Credit, any Issuer, the Administrative Agent or any Lender or any other Person, whether in connection with this Agreement, any other Loan Document or any other related or unrelated agreement or transaction;

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

(v) payment by the Issuer under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit; and

(vi) any other act or omission to act or delay of any kind of the Issuer, the Lenders, the Administrative Agent or any other Person or any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.3, constitute a legal or equitable discharge of the Borrower’s obligations hereunder.

Any action taken or omitted to be taken by the relevant Issuer under or in connection with any Letter of Credit, if taken or omitted in the absence of gross negligence or willful misconduct, shall not result in any liability of such Issuer to the Borrower or any Lender. In determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof, the Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary and, in making any payment under any Letter of Credit, the Issuer may rely exclusively on the documents presented to it under such Letter of Credit as to any and all matters set forth therein, including reliance on the amount of any draft presented under such Letter of Credit, whether or not the amount due to the beneficiary thereunder equals the amount of such draft and whether or not any document presented pursuant to such Letter of Credit proves to be insufficient in any respect, if such document on its face appears to be in order, and whether or not any other statement or any other document presented pursuant to such Letter of Credit proves to be forged or invalid or any statement therein proves to be inaccurate or untrue in any respect whatsoever, and any noncompliance in any immaterial respect of the documents presented under such Letter of Credit with the terms thereof shall, in each case, be deemed not to constitute willful misconduct or gross negligence of the Issuer.

2.4 Reduction and Termination of the Commitments. The Borrower may, upon at least three Business Days’ prior notice to the Administrative Agent, terminate in whole or reduce in part ratably the unused portions of the respective Revolving Credit Commitments of the Lenders; provided, however, that each partial reduction shall be in an aggregate amount of not less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof. In addition, all outstanding Revolving Credit Commitments shall terminate on the Revolving Credit Termination Date.

2.5 Repayment of Loans. The Borrower promises to repay the entire unpaid principal amount of the Revolving Loans on the Scheduled Termination Date, or earlier if otherwise required by the terms hereof.

(a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing Indebtedness of the Borrower to such Lender resulting from each Revolving Loan of such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement.

(b) (i) The Administrative Agent, acting as agent of the Borrower solely for this purpose and for tax purposes, shall establish and maintain at its address referred to in Section 10.8 (Notices) a record of ownership (the “Register”) in which the Administrative Agent agrees to register by book entry the Administrative Agent’s, each Lender’s and each Issuer’s interest in each Revolving Loan, each Letter of Credit and each Reimbursement Obligation and in the right to receive any payments hereunder and any assignment of any such interest or rights. In addition, the Administrative Agent, acting as agent of the Borrower solely for this purpose and for tax purposes, shall establish and maintain accounts in the Register in accordance with its usual practice in which it shall record (A) the names and addresses of the Lenders, (B) the Revolving Credit Commitments of each Lender from time to time, (C) the amount of each Revolving Loan made and, if a Eurodollar Rate Loan, the Interest Period applicable thereto, (D) the amount of any drawn Letters of Credit, (E) the amount of any principal or interest due and payable, and paid, by the Borrower to, or for the account of, each Lender hereunder, (F) the amount that is due and payable, and paid, by the Borrower to, or for the account of, each Issuer, including the amount of Letter Credit Obligations (specifying the amount of any Reimbursement Obligations) due and payable to an Issuer, and (G) the amount of any sum received by the Administrative Agent hereunder from the Borrower, whether such sum constitutes principal or interest (and the type of Revolving Loan to which it applies), fees, expenses or other amounts due under the Loan Documents and each Lender’s and Issuer’s, as the case may be, share thereof, if applicable.

(ii) Notwithstanding anything to the contrary contained in this Agreement, the Revolving Loans (including the Revolving Credit Notes evidencing such Revolving Loans) and the drawn Letters of Credit are registered obligations and the right, title, and interest of the Lenders and the Issuers and their assignees in and to such Revolving Loans or drawn Letters of Credit, as the case may be, shall be transferable only upon notation of such transfer in the Register. A Revolving Credit Note shall only evidence the Lender’s or a registered assignee’s right, title and interest in and to the related Revolving Loan, and in no event is any such Revolving Credit Note to be considered a bearer instrument or obligation. This Section 2.6(b) and Section 10.2 (Assignments and Participations) shall be construed so that the Revolving Loans and drawn Letters of Credit are at all times maintained in “registered form” within the meaning of Sections 163(f), 871(h)(2) and 881(c)(2) of the Code and any related regulations (or any successor provisions of the Code or such regulations).

(c) The entries made in the Register and in the accounts therein maintained pursuant to clauses (a) and (b) above shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations recorded therein; provided, however, 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 obligations of the Borrower to repay the Revolving Loans in accordance with their terms. In addition, the Loan Parties, the Administrative Agent, the Lenders and the Issuers shall treat each Person whose name is recorded in the Register as a Lender for all purposes of this Agreement. Information contained in the Register with respect to any Lender or Issuer shall be available for inspection by the Borrower, the Administrative Agent, such Lender or such Issuer at any reasonable time and from time to time upon reasonable prior notice.

(d) Notwithstanding any other provision of the Agreement, in the event that any Lender requests that the Borrower execute and deliver a promissory note or notes payable to such Lender in order to evidence the Indebtedness owing to such Lender by the Borrower hereunder, the Borrower shall promptly execute and deliver a Revolving Credit Note or Revolving Credit Notes to such Lender evidencing any Revolving Loans of such Lender, substantially in the form of Exhibit E (Form of Revolving Credit Note).

2.7 Optional Prepayments. The Borrower may prepay the outstanding principal amount of the Revolving Loans in whole or in part at any time; provided, however, that if any prepayment of any Eurodollar Rate Loan is made by the Borrower other than on the last day of an Interest Period for such Loan, the Borrower shall also pay any amount owing pursuant to Section 2.13(e) (Breakage Costs). Partial prepayments of Revolving Loans shall be in an aggregate principal amount of not less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof.

2.8 Mandatory Prepayments. If at any time, the aggregate principal amount of Revolving Credit Outstandings exceeds the aggregate Revolving Credit Commitments at such time, the Borrower shall forthwith prepay the Revolving Loans then outstanding in an amount equal to such excess. If any such excess remains after repayment in full of the aggregate outstanding Revolving Loans, the Borrower shall provide cash collateral for the then outstanding Letter of Credit Obligations in the manner set forth in Section 8.2 (Actions in Respect of Letters of Credit) in an amount equal to 105% of such excess.

(a) Rate of Interest. All Revolving Loans and the outstanding amount of all other Obligations shall bear interest, in the case of Revolving Loans, on the unpaid principal amount thereof from the date such Revolving Loans are made and, in the case of such other Obligations, from the date such other Obligations are due and payable until, in all cases, paid in full, except as otherwise provided in clause (c) below, as follows:

(i) if a Base Rate Loan or such other Obligation, at a rate per annum equal to the sum of (A) the Base Rate as in effect from time to time and (B) the Applicable Margin for Revolving Loans that are Base Rate Loans; and

(ii) if a Eurodollar Rate Loan, at a rate per annum equal to the sum of (A) the Eurodollar Rate determined for the applicable Interest Period and (B) the Applicable Margin in effect from time to time during such Eurodollar Interest Period.

(b) Interest Payments. (i) Interest accrued on each Base Rate Loan shall be payable in arrears (A) on the first Business Day of each calendar quarter, commencing on the first such day following the making of such Base Rate Loan, and (B) if not previously paid in full, at maturity (whether by acceleration or otherwise) of such Base Rate Loan, (ii) interest accrued on each Eurodollar Rate Loan shall be payable in arrears (A) on the last day of each Interest Period applicable to such Loan (and, if such Interest Period has a duration of more than three months, on each date during such Interest Period occurring every three months from the first day of such Interest Period), (B) upon the payment or prepayment thereof in full or in part and (C) if not previously paid in full, at maturity (whether by acceleration or otherwise) of such Eurodollar Rate Loan, and (iii) interest accrued on the amount of all other Obligations shall be payable on demand from and after the time such Obligation becomes due and payable (whether by acceleration or otherwise).

(c) Default Interest. Notwithstanding the rates of interest specified in clause (a) above or elsewhere herein, effective immediately upon the occurrence of an Event of Default specified in Section 8.1(a) and for as long thereafter as such Event of Default shall be continuing, the principal balance of all Loans and the amount of all other Obligations then due and payable shall bear interest at a rate that is 2% per annum in excess of the rate of interest applicable to such Loans or other Obligations from time to time. Such interest shall be payable on the date that would otherwise be applicable to such interest pursuant to clause (b) above or otherwise on demand.

(a) The Borrower may elect (i) at any time on any Business Day to convert Base Rate Loans or any portion thereof to Eurodollar Rate Loans and (ii) at the end of any applicable Interest Period, to convert Eurodollar Rate Loans or any portion thereof into Base Rate Loans or to continue such Eurodollar Rate Loans or any portion thereof for an additional Interest Period; provided, however, that the aggregate amount of the Eurodollar Loans for each Interest Period must be in the amount of at least $5,000,000 or an integral multiple of $1,000,000 in excess thereof. Each conversion or continuation shall be allocated among the Loans of each Lender in accordance with such Lender’s Ratable Portion. Each such election shall be in substantially the form of Exhibit F (a “Notice of Conversion or Continuation”) and shall be made by giving the Administrative Agent at least three Business Days’ prior written notice specifying (A) the amount and type of Loan being converted or continued, (B) in the case of a conversion to or a continuation of Eurodollar Rate Loans, the applicable Interest Period and (C) in the case of a conversion, the date of such conversion.

(b) The Administrative Agent shall promptly notify each Lender of its receipt of a Notice of Conversion or Continuation and of the options selected therein. Notwithstanding the foregoing, no conversion in whole or in part of Base Rate Loans to Eurodollar Rate Loans and no continuation in whole or in part of Eurodollar Rate Loans upon the expiration of any applicable Interest Period shall be permitted at any time at which (A) a Default or an Event of Default shall have occurred and be continuing or (B) the continuation of, or conversion into, a Eurodollar Rate Loan would violate any provision of 2.13 (Special Provisions Governing Eurodollar Rate Loans). If, within the time period required under the terms of this Section 2.10, the Administrative Agent does not receive a Notice of Conversion or Continuation from the Borrower containing a permitted election to continue any Eurodollar Rate Loans for an additional Interest Period or to convert any such Loans, then, upon the expiration of the applicable Interest Period, such Loans shall be automatically converted to Base Rate Loans. Each Notice of Conversion or Continuation shall be irrevocable.

(a) Facility Fee. The Borrower agrees to pay in immediately available Dollars to the Administrative Agent for the account of each Lender a fee (the “Facility Fee”) on the daily amount of such Lender’s Revolving Credit Commitment, whether used or unused, and when the Revolving Credit Commitment has been terminated, on the Revolving Credit Outstandings of such Lender, at the Applicable Facility Fee Rate from the date hereof through the later of (i) the Revolving Credit Termination Date and (ii) the date on which all outstanding Revolving Loans are paid in full and all Letter of Credit Obligations have been cash collateralized in an amount equal to 105% of such Letter of Credit Obligations in the manner set forth in Section 8.2 (Actions in Respect of Letters of Credit). All Facility Fees shall be payable in arrears (x) on the first Business Day of each calendar quarter, commencing on the first such Business Day following the Closing Date, (y) on the Revolving Credit Termination Date and (z) on the date on which all outstanding Revolving Loans are paid in full and all Letter of Credit Obligations have been cash collateralized in an amount equal to 105% of such Letter of Credit Obligations in the manner set forth in Section 8.2 (Actions in Respect of Letters of Credit).

(b) Utilization Fee. The Borrower agrees to pay in immediately available Dollars to the Administrative Agent for the account of each Lender a fee (the “Utilization Fee”) on such Lender’s Ratable Portion of the Revolving Credit Outstandings at the Utilization Fee Rate for each day on which the Revolving Credit Outstandings exceeds 50% of the aggregate Revolving Credit Commitments, during the period from the date hereof through the later of (i) the Revolving Credit Termination Date and (ii) the date on which all outstanding Revolving Loans are paid in full and all Letter of Credit Obligations have been cash collateralized in an amount equal to 105% of such Letter of Credit Obligations in the manner

set forth in Section 8.2 (Actions in Respect of Letters of Credit). All Utilization Fees shall be payable in arrears (x) on the first Business Day of each calendar quarter, commencing on the first such Business Day following the Closing Date, (y) on the Revolving Credit Termination Date and (z) on the date on which all outstanding Revolving Loans are paid in full and all Letter of Credit Obligations have been cash collateralized in an amount equal to 105% of such Letter of Credit Obligations in the manner set forth in Section 8.2 (Actions in Respect of Letters of Credit).

(c) Letter of Credit Fees. The Borrower agrees to pay the following amounts with respect to Letters of Credit issued by any Issuer:

(i) to the Administrative Agent for the account of each Issuer of a Letter of Credit, with respect to each Letter of Credit issued by such Issuer, an issuance fee equal to 0.10% per annum of the maximum undrawn face amount of such Letter of Credit, payable in arrears (A) on the first Business Day of each calendar quarter, commencing on the first such Business Day following the issuance of such Letter of Credit and (B) on the Revolving Credit Termination Date;

(ii) to the Administrative Agent for the ratable benefit of the Lenders, with respect to each Letter of Credit, a fee accruing in Dollars at a rate per annum equal to the Applicable Margin for Revolving Loans that are Eurodollar Rate Loans on the maximum undrawn face amount of such Letter of Credit, payable in arrears (A) on the first Business Day of each calendar quarter, commencing on the first such Business Day following the issuance of such Letter of Credit and (B) on the Revolving Credit Termination Date; provided, however, that during the continuance of an Event of Default, such fee shall be increased by two percent per annum (instead of, and not in addition to, any increase pursuant to Section 2.9(c) (Interest)) and shall be payable on demand; and

(iii) to the Issuer of any Letter of Credit, with respect to the issuance, amendment or transfer of each Letter of Credit and each drawing made thereunder, documentary and processing charges in accordance with such Issuer’s standard schedule for such charges in effect at the time of issuance, amendment, transfer or drawing, as the case may be.

(d) Additional Fees. The Borrower has agreed to pay to the Administrative Agent and the Arrangers additional fees, the amount and dates of payment of which are embodied in the Fee Letter.

(a) The Borrower shall make each payment hereunder (including fees and expenses) not later than 11:00 a.m. (New York time) on the day when due, in Dollars, to the Administrative Agent at its address referred to in Section 10.8 (Notices) in immediately available funds without set-off or counterclaim. The Administrative Agent shall promptly thereafter cause to be distributed in immediately available funds relating to the payment of principal, interest or fees to the Lenders, in accordance with the application of payments set forth in clause (f) for the account of their respective Applicable Lending Offices; provided, however, that amounts payable pursuant to Sections 2.14 (Capital Adequacy), 2.15 (Taxes) or 2.13(c) or (d) (Special Provisions Governing Eurodollar Rate Loans) shall be paid only to the affected Lender or Lenders. Payments received by the Administrative Agent after 11:00 a.m. (New York time) shall be deemed to be received on the next Business Day.

(b) All computations of interest in respect of interest at the Base Rate shall be made by the Administrative Agent on the basis of a 365/366-day year and actual days elapsed; all other

computations of interest and of fees shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest and fees are payable. Each determination by the Administrative Agent of a rate of interest hereunder shall be conclusive and binding for all purposes, absent manifest error.

(c) Each payment by the Borrower of any Loan, Reimbursement Obligation (including interest or fees in respect thereof) and each reimbursement of various costs, expenses or other Obligation shall be made in Dollars.

(d) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, the due date for such payment shall be extended to the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided, however, that if such extension would cause payment of interest on or principal of any Eurodollar Rate Loan to be made in the next calendar month, such payment shall be made on the immediately preceding Business Day. All repayments of any Revolving Loans shall be applied as follows: first, to repay such Loans outstanding as Base Rate Loans and then, to repay such Loans outstanding as Eurodollar Rate Loans, with those Eurodollar Rate Loans having earlier expiring Eurodollar Interest Periods being repaid prior to those having later expiring Eurodollar Interest Periods.

(e) Unless the Administrative Agent shall have received notice from the Borrower to the Lenders prior to the date on which any payment is due hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon (at the Federal Funds Rate for the first Business Day and thereafter, at the rate applicable to Base Rate Loans) for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent.

(f) Except for payments and other amounts received by the Administrative Agent and applied in accordance with the provisions of clause (g) below, all payments and any other amounts received by the Administrative Agent from or for the benefit of the Borrower shall be applied as follows: first, to pay principal of, and interest on, any portion of the Loans the Administrative Agent may have advanced pursuant to the express provisions of this Agreement on behalf of any Lender, for which the Administrative Agent has not then been reimbursed by such Lender or the Borrower, second, to pay all other Obligations then due and payable and third, as the Borrower so designates. Payments in respect of Revolving Loans received by the Administrative Agent shall be distributed to each Lender in accordance with such Lender’s Ratable Portion of the Revolving Credit Commitments and all payments of fees and all other payments in respect of any other Obligation shall be allocated among such of the Lenders as are entitled thereto and, for such payments allocated to the Lenders, in proportion to their respective Ratable Portions.

(g) The Borrower hereby irrevocably waives the right to direct the application of any and all payments in respect of the Obligations after the occurrence and during the continuance of an Event of Default and agrees that, notwithstanding the provisions of clause (f) above, the Administrative Agent may, and, upon either (A) the written direction of the Required Lenders or (B) the acceleration of the Obligations pursuant to Section 8.1, shall, apply all payments in respect of any Obligations in the following order:

(i) first, to pay interest on and then principal of any portion of the Revolving Loans that the Administrative Agent may have advanced on behalf of any Lender for which the Administrative Agent has not then been reimbursed by such Lender or the Borrower;

(ii) second, to pay Obligations in respect of any expense reimbursements or indemnities then due to the Administrative Agent;

(iii) third, to pay Obligations in respect of any expense reimbursements or indemnities then due to the Lenders and the Issuers;

(iv) fourth, to pay Obligations in respect of any fees then due to the Administrative Agent, the Lenders and the Issuers;

(v) fifth, to pay interest then due and payable in respect of the Revolving Loans and Reimbursement Obligations;

(vi) sixth, to pay or prepay principal amounts on the Revolving Loans and Reimbursement Obligations and to provide cash collateral for outstanding Letter of Credit Undrawn Amounts in the manner described in Section 8.2 (Actions in Respect of Letters of Credit), ratably to the aggregate principal amount of such Loans, Reimbursement Obligations and Letter of Credit Undrawn Amounts; and

provided, however, that if sufficient funds are not available to fund all payments to be made in respect of any Obligation described in any of clauses (i) through (vii) above, the available funds being applied with respect to any such Obligation (unless otherwise specified in such clause) shall be allocated to the payment of such Obligation ratably, based on the proportion of the Administrative Agent’s and each Lender’s or Issuer’s interest in the aggregate outstanding Obligations described in such clauses. The order of priority set forth in clauses (i) through (vii) above may at any time and from time to time be changed by the agreement of the Required Lenders without necessity of notice to or consent of or approval by the Borrower or by any other Person that is not a Lender or Issuer. The order of priority set forth in clauses (i) through (iv) above may be changed only with the prior written consent of the Administrative Agent in addition to that of the Required Lenders.

(h) At the option of the Administrative Agent, Reimbursement Obligations, interest, fees, expenses and other sums due and payable in respect of the Revolving Loans may be paid from the proceeds of Revolving Loans. The Borrower hereby authorizes the Lenders to make such Revolving Loans pursuant to Section 2.2(a) (Borrowing Procedures) from time to time in the amounts of any and all Reimbursement Obligations, interest, fees, expenses and other sums payable in respect of the Revolving Loans, and further authorizes the Administrative Agent to give the Lenders notice of any Borrowing with respect to such Revolving Loans and to distribute the proceeds of such Revolving Loans to pay such amounts. The Borrower agrees that all such Revolving Loans so made shall be deemed to have been requested by it (irrespective of the satisfaction of the conditions in Section 4.2 (Conditions Precedent to Each Extension of Credit), which conditions the Lenders irrevocably waive) and directs that all proceeds thereof shall be used to pay such amounts.

(a) Determination of Interest Rate. The Eurodollar Rate for each Interest Period for Eurodollar Rate Loans shall be determined by the Administrative Agent pursuant to the procedures set

forth in the definition of “Eurodollar Rate.” The Administrative Agent’s determination shall be presumed to be correct absent manifest error and shall be binding on the Borrower.

(b) Interest Rate Unascertainable, Inadequate or Unfair. In the event that (i) the Administrative Agent determines that adequate and fair means do not exist for ascertaining the applicable interest rates by reference to which the Eurodollar Rate then being determined is to be fixed or (ii) the Required Lenders notify the Administrative Agent that the Eurodollar Rate for any Interest Period will not adequately reflect the cost to the Lenders of making or maintaining such Loans for such Interest Period, the Administrative Agent shall forthwith so notify the Borrower and the Lenders, whereupon each Eurodollar Loan shall automatically, on the last day of the current Interest Period for such Loan, convert into a Base Rate Loan and the obligations of the Lenders to make Eurodollar Rate Loans or to convert Base Rate Loans into Eurodollar Rate Loans shall be suspended until the Administrative Agent shall notify the Borrower that the Required Lenders have determined that the circumstances causing such suspension no longer exist.

(c) Increased Costs. If at any time any Lender determines that the introduction of, or any change in or in the interpretation of, any law, treaty or governmental rule, regulation or order occurring after the date hereof (other than any change by way of imposition or increase of reserve requirements included in determining the Eurodollar Rate) or the compliance by such Lender with any guideline, request or directive from any central bank or other Governmental Authority issued after the date hereof (whether or not having the force of law), shall have the effect of increasing the cost to such Lender of agreeing to make or making, funding or maintaining any Eurodollar Rate Loans, then the Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender additional amounts sufficient to compensate such Lender for such increased cost. A certificate as to the amount of such increased cost, submitted to the Borrower and the Administrative Agent by such Lender, shall be conclusive and binding for all purposes, absent manifest error. The Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs incurred more than 90 days prior to the date that such Lender notifies the Borrower of the change in law giving rise to such increased costs and of such Lender’s intention to claim compensation therefor; provided, however, that if the change in law giving rise to such increased costs is retroactive, then the 90-day period referred to above shall be extended to include the period of retroactive effect thereof (to the extent that such period of retroactive effect is not already included in such 90-day period).

(d) Illegality. Notwithstanding any other provision of this Agreement, if any Lender determines that the introduction of, or any change in or in the interpretation of, any law, treaty or governmental rule, regulation or order after the date of this Agreement shall make it unlawful, or any central bank or other Governmental Authority shall assert that it is unlawful, for any Lender or its Eurodollar Lending Office to make Eurodollar Rate Loans or to continue to fund or maintain Eurodollar Rate Loans, then, on notice thereof and demand therefor by such Lender to the Borrower through the Administrative Agent, (i) the obligation of such Lender to make or to continue Eurodollar Rate Loans and to convert Base Rate Loans into Eurodollar Rate Loans shall be suspended, and each such Lender shall make a Base Rate Loan as part of any requested Borrowing of Eurodollar Rate Loans and (ii) if the affected Eurodollar Rate Loans are then outstanding, the Borrower shall immediately convert each such Loan into a Base Rate Loan. If, at any time after a Lender gives notice under this clause (d), such Lender determines that it may lawfully make Eurodollar Rate Loans, such Lender shall promptly give notice of that determination to the Borrower and the Administrative Agent, and the Administrative Agent shall promptly transmit the notice to each other Lender. The Borrower’s right to request, and such Lender’s obligation, if any, to make Eurodollar Rate Loans shall thereupon be restored.

(e) Breakage Costs. In addition to all amounts required to be paid by the Borrower pursuant to Section 2.9 (Interest), the Borrower shall compensate each Lender, upon demand, for all losses, expenses and liabilities (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund or maintain such Lender’s Eurodollar Rate Loans to the Borrower but excluding any loss of the Applicable Margin on the relevant Loans) that such Lender may sustain (i) if for any reason (other than solely by reason of such Lender being a Non-Funding Lender) a proposed Borrowing, conversion into or continuation of Eurodollar Rate Loans does not occur on a date specified therefor in a Notice of Borrowing or a Notice of Conversion or Continuation given by the Borrower or in a telephonic request by it for borrowing or conversion or continuation or a successive Interest Period does not commence after notice therefor is given pursuant to Section 2.10 (Conversion/Continuation Option), (ii) if for any reason any Eurodollar Rate Loan is prepaid (including mandatorily pursuant to Section 2.8) on a date that is not the last day of the applicable Interest Period, (iii) as a consequence of a required conversion of a Eurodollar Rate Loan to a Base Rate Loan as a result of any of the events indicated in clause (d) above or (iv) as a consequence of any failure by the Borrower to repay Eurodollar Rate Loans when required by the terms hereof. The Lender making demand for such compensation shall deliver to the Borrower concurrently with such demand a written statement as to such losses, expenses and liabilities, and this statement shall be prima facie evidence as to the amount of compensation due to such Lender, absent manifest error.

2.14 Capital Adequacy. If at any time any Lender determines that (a) the adoption of, or any change in or in the interpretation of, any law, treaty or governmental rule, regulation or order after the date of this Agreement regarding capital adequacy, (b) compliance with any such law, treaty, rule, regulation or order or (c) compliance with any guideline or request or directive from any central bank or other Governmental Authority issued after the date hereof (whether or not having the force of law) shall have the effect of reducing the rate of return on such Lender’s (or any corporation controlling such Lender’s) capital as a consequence of its obligations hereunder or under or in respect of any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such adoption, change, compliance or interpretation, then, upon demand from time to time by such Lender (with a copy of such demand to the Administrative Agent), the Borrower shall pay to the Administrative Agent for the account of such Lender, from time to time as specified by such Lender, additional amounts sufficient to compensate such Lender for such reduction. A certificate as to such amounts submitted to the Borrower and the Administrative Agent by such Lender shall be conclusive and binding for all purposes absent manifest error. The Borrower shall not be required to compensate a Lender pursuant to this Section for any reduced rate of return incurred more than 90 days prior to the date that such Lender notifies the Borrower of the change in law giving rise to such reduced rate of return and of such Lender’s intention to claim compensation therefor; provided, however, that if the change in law giving rise to such reduction is retroactive, then the 90-day period referred to above shall be extended to include the period of retroactive effect thereof (to the extent that such period of retroactive effect is not already included in such 90-day period).

(a) Except as otherwise provided in this Section 2.15, any and all payments by any Loan Party under each Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding (i) in the case of each Lender, each Issuer and the Administrative Agent (A) taxes measured by its net income, and franchise taxes imposed on it, and similar taxes imposed by the jurisdiction (or any political subdivision thereof) under the laws of which such Lender, such Issuer or the Administrative Agent (as the case may be) is organized or in which its principal office is located or, in the case of any Lender, in which its Applicable Lending Office is located and (B) any U.S. withholding taxes payable with respect to payments under the Loan Documents under laws (including any statute, treaty or

regulation) in effect on the Closing Date (or, in the case of (x) an Eligible Assignee, the date of the Assignment and Acceptance, (y) a successor Administrative Agent, the date of the appointment of such Administrative Agent, and (z) a successor Issuer, the date such Issuer becomes an Issuer) applicable to such Lender, such Issuer or the Administrative Agent, as the case may be, or is attributable to such Non-U.S. Lender’s failure to comply with Section 2.15(f), but not excluding any U.S. withholding taxes payable as a result of any change in such laws occurring after the Closing Date (or the date of such Assignment and Acceptance or the date of such appointment of such Administrative Agent or the date such Issuer becomes an Issuer) and (ii) in the case of each Lender or each Issuer, taxes measured by its net income, and franchise taxes imposed on it as a result of a present or former connection between such Lender or such Issuer (as the case may be) and the jurisdiction of the Governmental Authority imposing such tax or any taxing authority thereof or therein (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If any Taxes shall be required by law to be deducted from or in respect of any sum payable under any Loan Document to any Lender, any Issuer or the Administrative Agent (w) the sum payable shall be increased as may be necessary so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 2.15, such Lender, such Issuer or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (x) the relevant Loan Party shall make such deductions, (y) the relevant Loan Party shall pay the full amount deducted to the relevant taxing authority or other authority in accordance with applicable law and (z) the relevant Loan Party shall deliver to the Administrative Agent evidence of such payment.

(b) In addition, each Loan Party agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies of the United States or any political subdivision thereof or any applicable foreign jurisdiction, and all liabilities with respect thereto, in each case arising from any payment made under any Loan Document or from the execution, delivery or registration of, or otherwise with respect to, any Loan Document (collectively, “Other Taxes”).

(c) Each Loan Party shall, jointly and severally, indemnify each Lender, each Issuer and the Administrative Agent for the full amount of Taxes and Other Taxes (including any Taxes and Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.15) paid by such Lender, such Issuer or the Administrative Agent (as the case may be) and any liability (including for penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. This indemnification shall be made within 30 days from the date such Lender, such Issuer or the Administrative Agent (as the case may be) makes written demand therefor.

(d) Within 30 days after the date of any payment of Taxes or Other Taxes by any Loan Party, the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 10.8 (Notices), the original or a certified copy of a receipt evidencing payment thereof.

(e) Without prejudice to the survival of any other agreement of any Loan Party hereunder or under the Guaranty, the agreements and obligations of such Loan Party contained in this Section 2.15 shall survive the payment in full of the Obligations.

(f) Each Non-U.S. Lender that is entitled to an exemption from U.S. withholding tax, or that is subject to such tax at a reduced rate under an applicable tax treaty, shall (v) on or prior to the Closing Date in the case of each Non-U.S. Lender that is a signatory hereto, (w) on or prior to the date of the Assignment and Acceptance pursuant to which such Non-U.S. Lender becomes a Lender, on or prior to the date a successor Issuer becomes an Issuer or the date a successor Administrative Agent becomes the Administrative Agent hereunder, (x) on or prior to the date on which any such form or

certification expires or becomes obsolete, (y) after the occurrence of any event requiring a change in the most recent form or certification previously delivered by it to the Borrower and the Administrative Agent, and (z) from time to time thereafter if requested by the Borrower or the Administrative Agent, provide the Administrative Agent and the Borrower with two completed originals of each of the following, as applicable:

(i) (A) Form W-8ECI (claiming exemption from U.S. withholding tax because the income is effectively connected with a U.S. trade or business) or any successor form, (B) Form W-8BEN (claiming exemption from, or a reduction of, U.S. withholding tax under an income tax treaty) or any successor form, (C) in the case of a Non-U.S. Lender claiming exemption under Sections 871(h) or 881(c) of the Code, a Form W-8BEN (claiming exemption from U.S. withholding tax under the portfolio interest exemption) or any successor form or (D) any other applicable form, certificate or document prescribed by the IRS certifying as to such Non-U.S. Lender’s entitlement to such exemption from U.S. withholding tax or reduced rate with respect to all payments to be made to such Non-U.S. Lender under the Loan Documents. Unless the Borrower and the Administrative Agent have received forms or other documents satisfactory to them indicating that payments under any Loan Document to or for a Non-U.S. Lender are not subject to U.S. withholding tax or are subject to such tax at a rate reduced by an applicable tax treaty, the Loan Parties and the Administrative Agent shall withhold amounts required to be withheld by applicable Requirements of Law from such payments at the applicable statutory rate.

(ii) Each U.S. Lender shall (v) on or prior to the Closing Date in the case of each U.S. Lender that is a signatory hereto, (w) on or prior to the date of the Assignment and Acceptance pursuant to which such U.S. Lender becomes a Lender or an Issuer or on or prior to the date a successor Administrative Agent becomes the Administrative Agent hereunder, (x) on or prior to the date on which any such form or certification expires or becomes obsolete, (y) after the occurrence of any event requiring a change in the most recent form or certification previously delivered by it to the Borrower and the Administrative Agent, and (z) from time to time if requested by the Borrower or the Administrative Agent, provide the Administrative Agent and the Borrower with two completed originals of Form W-9 (certifying that such U.S. Lender is entitled to an exemption from U.S. backup withholding tax) or any successor form. Solely for purposes of this Section 2.15(f), a U.S. Lender shall not include a Lender, an Issuer or an Administrative Agent that may be treated as an exempt recipient based on the indicators described in Treasury Regulation section 1.6049-4(c)(1)(ii).

(g) Any Lender claiming any additional amounts payable pursuant to this Section 2.15 shall use its reasonable efforts (consistent with its internal policies and Requirements of Law) to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that would be payable or may thereafter accrue and would not, in the sole determination of such Lender, be otherwise disadvantageous to such Lender.

(h) If any Lender, Issuer or the Administrative Agent, as determined in its reasonable discretion, ever receives any refund of or credit with respect to any Taxes or Other Taxes as to which it has been indemnified by any Loan Party, or with respect to which any Loan Party has paid additional amounts pursuant to this Section 2.15, it shall pay over to such Loan Party an amount equal to such refund or credit (but only to the extent of indemnity payments made, or additional amounts paid, by any Loan Party under this Section 2.15 with respect to the Taxes or Other Taxes giving rise to such refund or credit), net of all out-of-pocket expenses of such Lender, Issuer or the Administrative Agent and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund or credit); provided that such Loan Party, upon the request of such Lender, Issuer or the Administrative

Agent, agrees to repay the amount paid over to the Loan Party, to such Lender, Issuer or the Administrative Agent in the event the Lender, Issuer or the Administrative Agent is required to repay such refund or credit to such Governmental Authority. This paragraph shall not be construed to require the Lender, Issuer or the Administrative Agent to make available its tax returns (or any other information relating to its taxes which it deems confidential) to any Loan Party or any other Person.

(a) In the event that (i)(A) any Lender makes a claim under Sections 2.13(c) (Increased Costs) or 2.14 (Capital Adequacy), (B) it becomes illegal for any Lender to continue to fund or make any Eurodollar Rate Loan and such Lender notifies the Borrower pursuant to Section 2.13(d) (Illegality), (C) any Loan Party is required to make any payment pursuant to Section 2.15 (Taxes) that is attributable to a particular Lender or (D) any Lender becomes a Non-Funding Lender, (ii) in the case of clause (i)(A) above, as a consequence of increased costs in respect of which such claim is made, the effective rate of interest payable to such Lender under this Agreement with respect to its Loans materially exceeds the effective average annual rate of interest payable to the Required Lenders under this Agreement and (iii) in the case of clause (i)(A),(B) and (C) above, Lenders holding at least 75% of the Commitments are not subject to such increased costs or illegality, payment or proceedings (any such Lender, an “Affected Lender”), the Borrower may substitute any Lender and, if reasonably acceptable to the Administrative Agent, any other Eligible Assignee (a “Substitute Institution”) for such Affected Lender hereunder, after delivery of a written notice (a “Substitution Notice”) by the Borrower to the Administrative Agent and the Affected Lender within a reasonable time (in any case not to exceed 90 days) following the occurrence of any of the events described in clause (i) above that the Borrower intends to make such substitution; provided, however, that, if more than one Lender claims increased costs, illegality or right to payment arising from the same act or condition and such claims are received by the Borrower within 30 days of each other, then the Borrower may substitute all, but not (except to the extent the Borrower has already substituted one of such Affected Lenders before the Borrower’s receipt of the other Affected Lenders’ claim) less than all, Lenders making such claims.

(b) If the Substitution Notice was properly issued under this Section 2.16, the Affected Lender shall sell, and the Substitute Institution shall purchase, all rights and claims of such Affected Lender under the Loan Documents and the Substitute Institution shall assume, and the Affected Lender shall be relieved of, the Affected Lender’s Revolving Credit Commitments and all other prior unperformed obligations of the Affected Lender under the Loan Documents (other than in respect of any damages (which pursuant to Section 10.5 (Limitation of Liability), do not include exemplary or punitive damages, to the extent permitted by applicable law) in respect of any such unperformed obligations). Such purchase and sale (and the corresponding assignment of all rights and claims hereunder) shall be recorded in the Register maintained by the Administrative Agent and shall be effective on (and not earlier than) the later of (i) the receipt by the Affected Lender of its Ratable Portion of the Revolving Credit Outstandings, together with any other Obligations owing to it, (ii) the receipt by the Administrative Agent of an agreement in form and substance satisfactory to it and the Borrower whereby the Substitute Institution shall agree to be bound by the terms hereof and (iii) the payment in full to the Affected Lender in cash of all fees, unreimbursed costs and expenses and indemnities accrued and unpaid through such effective date. Upon the effectiveness of such sale, purchase and assumption, the Substitute Institution shall become a “Lender” hereunder for all purposes of this Agreement having a Revolving Credit Commitment in the amount of such Affected Lender’s Revolving Credit Commitment assumed by it and such Revolving Credit Commitment of the Affected Lender shall be terminated; provided, however, that all indemnities under the Loan Documents shall continue in favor of such Affected Lender.

(c) Each Lender agrees that, if it becomes an Affected Lender and its rights and claims are assigned hereunder to a Substitute Institution pursuant to this Section 2.16, it shall execute and

deliver to the Administrative Agent an Assignment and Acceptance to evidence such assignment, together with any Revolving Credit Note (if such Loans are evidenced by a Revolving Credit Note) evidencing the Loans subject to such Assignment and Acceptance; provided, however, that the failure of any Affected Lender to execute an Assignment and Acceptance shall not render such assignment invalid.

To induce the Agents, the Lenders and the Issuers to enter into this Agreement and to make the Revolving Loans and Issue or participate in the Letters of Credit, the MLP and the Borrower hereby represent and warrant to each Agent, each Lender and each Issuer that:

3.1 Financial Condition. The audited consolidated balance sheets of (a) the Borrower and its Subsidiaries, (b) Texas Gas and (c) Gulf South, each as at December 31, 2004, and the related audited consolidated statements of income and of cash flows for the period ended on such date, reported on by and accompanied by an unqualified report from Deloitte & Touche LLP, present fairly the consolidated financial condition of the Borrower, Texas Gas and Gulf South, respectively, as at such date, and the consolidated results of its operations and its consolidated cash flows for the period then ended. The unaudited consolidated balance sheets of (x) the Borrower and its Subsidiaries, (y) Texas Gas and (z) Gulf South, each as at June 30, 2005, and the related unaudited consolidated statements of income and cash flows for the six-month period ended on such date, present fairly the consolidated financial condition of the Borrower, Texas Gas and Gulf South, respectively, as at such date, and the consolidated results of its operations and its consolidated cash flows for the six-month period then ended (subject to normal year-end audit adjustments and the absence of notes). All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved (except as approved by the aforementioned firm of accountants and disclosed therein).

3.2 No Change. Since December 31, 2004 there has been no development or event that has had or could reasonably be expected to have a Material Adverse Effect.

3.3 Corporate Existence; Compliance with Law. Each of the MLP, the Borrower and their respective Subsidiaries (a) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, (b) has the limited partnership, limited liability company, corporate or other power and authority, and the legal right, to own and operate its Property, to lease the Property it operates as lessee and to conduct the business in which it is currently engaged, (c) is duly qualified as a foreign limited partnership, limited liability company, corporation or other organization and in good standing under the laws of each jurisdiction where its ownership, lease or operation of Property or the conduct of its business requires such qualification and (d) is in compliance with all Requirements of Law except, in the case of clauses (c) and (d), to the extent that the failure to comply therewith could not, in the aggregate, reasonably be expected to have a Material Adverse Effect.

3.4 Limited Partnership Power; Authorization; Enforceable Obligations. Each of the Loan Parties has the limited partnership (or equivalent) power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and, with respect to the Borrower, to borrow hereunder. Each of the Loan Parties has taken all necessary limited partnership (or equivalent) or other necessary action to authorize the execution, delivery and performance of the Loan Documents to which it is a party and, with respect to the Borrower, to authorize the borrowings on the terms and conditions of this Agreement. No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the borrowings hereunder or the execution, delivery, validity or enforceability of this Agreement or any of the other Loan Documents, except consents, authorizations, filings and notices described in Schedule 3.4, which

consents, authorizations, filings and notices have been obtained or made and are in full force and effect. No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the performance of this Agreement or any of the other Loan Documents, except routine consents, authorizations, filings and notices required to be made in the ordinary course of business. Each Loan Document has been duly executed and delivered on behalf of each Loan Party that is a party thereto. This Agreement constitutes, and each other Loan Document that is an agreement or instrument upon execution will constitute, a legal, valid and binding obligation of each Loan Party that is a party thereto, enforceable against such Loan Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law).

3.5 No Legal Bar. The execution, delivery and performance of this Agreement and the other Loan Documents, the borrowings hereunder and the use of the proceeds thereof will not violate any Requirement of Law or any material Contractual Obligation of the MLP, the Borrower or their respective Subsidiaries and will not result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any such Contractual Obligation.

3.6 No Material Litigation. Except as set forth on Schedule 3.6, no litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of the Borrower, threatened by or against the Borrower or any Borrower Affiliate, or against any of its or their respective properties or revenues (a) with respect to any of the Loan Documents or any of the transactions contemplated hereby or thereby, or (b) that could reasonably be expected to have a Material Adverse Effect.

3.8 Ownership of Property; Liens. Each of the MLP, the Borrower and each of their respective Subsidiaries has title in fee simple to, or a valid leasehold interest in, or a right of way or easement in all real property used or necessary for, and material to, the conduct of its business, and good title to, or a valid leasehold interest in, all its other Property used or necessary for, and material to, the conduct of its business, and none of such Property is subject to any Lien except as permitted by Section 7.2.

3.9 Taxes. Each of the MLP, the Borrower and each of their respective Subsidiaries has filed or caused to be filed all Federal, state and other material tax returns that are required to be filed and has paid all taxes shown to be due and payable on said returns or on any assessments made against it or any of its Property and all other taxes, fees or other charges imposed on it or any of its Property by any Governmental Authority (other than any the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the MLP, the Borrower and their respective Subsidiaries or any amount the failure to pay could not reasonably be expected to have a Material Adverse Effect); and no tax Lien has been filed, and, to the knowledge of the Borrower, no claim is being asserted, with respect to any such tax, fee or other charge.

3.10 ERISA. Neither a Reportable Event nor an “accumulated funding deficiency” (within the meaning of Section 412 of the Code or Section 302 of ERISA) has occurred during the five year period prior to the date on which this representation is made or deemed made with respect to any Plan, and each Plan has complied in all respects with the applicable provisions of ERISA and the Code, except any such failures to comply that could not reasonably be expected to have a Material Adverse

Effect. No termination of a Single Employer Plan has occurred under Section 4041(c) or Section 4042 of ERISA, and no Lien in favor of the PBGC or a Plan has arisen, during such five-year period. The present value of all accrued benefits under each Single Employer Plan (based on those assumptions used to fund such Plans) did not, as of the last annual valuation date prior to the date on which this representation is made or deemed made, exceed the value of the assets of such Plan allocable to such accrued benefits by an amount that could reasonably be expected to have a Material Adverse Effect. Neither the Borrower nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan that has resulted or could reasonably be expected to result in a material liability under ERISA, and neither the Borrower nor any Commonly Controlled Entity would become subject to any liability that could reasonably be expected to have a Material Adverse Effect if the Borrower or any such Commonly Controlled Entity were to withdraw completely from all Multiemployer Plans as of the valuation date most closely preceding the date on which this representation is made or deemed made. No such Multiemployer Plan is in Reorganization or Insolvent.

3.11 Use of Proceeds. The proceeds of the Revolving Loans shall be used solely for (a) the repayment on or around Closing Date of an intercompany loan by Boardwalk Pipelines Holding Corp. in an aggregate principal amount of $43,000,000 and (b) general partnership purposes. The proceeds of the Letters of Credit shall be used solely for general partnership purposes.

3.12 Environmental Matters. Other than exceptions to any of the following that could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect:

(a) The MLP, the Borrower and each of their respective Subsidiaries: (i) is, and within the period of all applicable statutes of limitation has been, in compliance with all applicable Environmental Laws; (ii) holds all Environmental Permits (each of which is in full force and effect) required for any of its current or intended operations or for any property owned, leased, or otherwise operated by it; and (iii) is, and within the period of all applicable statutes of limitation has been, in compliance with all of its Environmental Permits.

(b) There is no judicial, administrative, or arbitral proceeding (including any notice of violation or alleged violation) under or relating to any Environmental Law to which the MLP, the Borrower or any of their respective Subsidiaries is, or to the knowledge of the Borrower will be, named as a party that is pending or, to the knowledge of the Borrower, threatened.

3.13 Accuracy of Information, etc. No statement or information (other than the projections and pro forma financial information referred to in the following sentence) contained in this Agreement, any other Loan Document or any other material document or certificate furnished to the Administrative Agent or the Lenders or any of them, by or on behalf of the MLP, the Borrower or any of their respective Subsidiaries for use in connection with the transactions contemplated by this Agreement or the other Loan Documents (as modified or supplemented by other information so furnished on or before the time this representation is made or deemed made with respect thereto), contained as of the date such statement, information, document or certificate was so furnished, any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements contained herein or therein not misleading. The projections and pro forma financial information contained in the materials referenced above are based upon good faith estimates and assumptions believed by management of the Borrower to be reasonable at the time made, it being recognized by the Lenders that such financial information as it relates to future events is not to be viewed as fact and that actual results during the period or periods covered by such financial information may differ from the projected results set forth therein by a material amount.

3.14 Solvency. Both before and after giving effect to (a) the Revolving Loans and Letter of Credit Obligations to be made or extended on the Closing Date or such other date as Revolving Loans and Letter of Credit Obligations requested hereunder are made or extended, (b) the disbursement of the proceeds of such Revolving Loans pursuant to the instructions of the Borrower, and (c) the payment and accrual of all transaction costs in connection with the foregoing, each Loan Party is Solvent.

3.15 Subsidiaries; Borrower Information. (a) Set forth on Schedule 3.15(a) is a complete and accurate list showing, as of the Closing Date, all Subsidiaries of the MLP and the Borrower. Schedule 3.15(a) sets forth as of the Closing Date the name and jurisdiction of organization of each such Subsidiary, and as to each such Subsidiary, the percentage of each class of Capital Stock owned by each Loan Party. As of the Closing Date, there are no outstanding subscriptions, options, warrants, calls, rights or other agreements or commitments (other than stock options granted to employees or directors and directors’ qualifying shares) of any nature relating to any Capital Stock of the MLP, the Borrower or any of their respective Subsidiaries, except as disclosed on Schedule 3.15(a).

(b) Schedule 3.15(b) sets forth as of the Closing Date the name, address of principal place of business and tax identification number of the Borrower.

3.16 Margin Regulations. The Borrower is not engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U of the Federal Reserve Board), and no proceeds of any Revolving Loan will be used to purchase or carry any such margin stock or to extend credit to others for the purpose of purchasing or carrying any such margin stock in contravention of Regulation T, U or X of the Federal Reserve Board.

3.17 Investment Company Act; Public Utility Holding Company Act. None of the MLP, the Borrower or any of their respective Subsidiaries is (a) an “investment company” or an “affiliated person” of, or “promoter” or “principal underwriter” for, an “investment company,” as such terms are defined in the Investment Company Act of 1940, as amended, or (b) at any time prior to February 8, 2006, a “holding company” or an “affiliate” of a “holding company” or a “subsidiary company” of a “holding company”, as each such term is defined and used in the Public Utility Holding Company Act of 1935, as amended.

3.18 Insurance. All policies of insurance of any kind or nature of the Borrower or any of its Subsidiaries, including policies of life, fire, theft, product liability, public liability, property damage, other casualty, employee fidelity, workers’ compensation and employee health and welfare insurance, are in full force and effect and are of a nature and provide such coverage as is customarily carried by businesses of the size and character of such Person.

(a) No proceeds of the Loans will be used, directly or indirectly, in violation of the Trading with the Enemy Act, as amended, or any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive order relating thereto.

(d) Any Loan Party shall default in the observance or performance of any other agreement contained in this Agreement to be performed by it or any other Loan Document (other than as provided in clauses (a) through (c) of this Section 8.1), and such default shall continue unremedied for a period of 30 days after the earlier of (i) the date on which a Responsible Officer of the MLP or the Borrower becomes aware of such failure and (ii) the date on which written notice thereof shall have been given to the Borrower by the Administrative Agent or any Lender; or

(e) (i) The Borrower or any Borrower Affiliate shall fail to make any payment on any Indebtedness of the Borrower or any such Borrower Affiliate (other than the Obligations) or any Guarantee Obligation in respect of Indebtedness of any other Person, and, in each case, such failure relates to Indebtedness having a principal amount of $25,000,000 or more, when the same becomes due and payable (whether by scheduled maturity, required prepayment, acceleration, demand or otherwise)

and such failure continues beyond any period of grace provided with respect thereto, (ii) any other event shall occur or condition shall exist under any agreement or instrument relating to any such Indebtedness, if the effect of such event or condition is to accelerate the maturity of such Indebtedness, (iii) any other event shall occur (other than default in the observance of reporting and notice covenants) or condition shall exist under any agreement or instrument relating to any such Indebtedness, if the effect of such event or condition is to permit the acceleration of the maturity of such Indebtedness or (iv) any such Indebtedness shall become or be declared to be due and payable, or be required to be prepaid or repurchased (other than by a regularly scheduled required prepayment), prior to the stated maturity thereof; or

(f) (i) The Borrower or any Borrower Affiliate shall commence any case, proceeding or other action (A) under any existing or future law of any jurisdiction, domestic or foreign, relating to bankruptcy, insolvency, reorganization or relief of debtors, seeking to have an order for relief entered with respect to it, or seeking to adjudicate it a bankrupt or insolvent, or seeking reorganization, arrangement, adjustment, winding up, liquidation, dissolution, composition or other relief with respect to it or its debts, or (B) seeking appointment of a receiver, trustee, custodian, conservator or other similar official for it or for all or any substantial part of its assets, or the Borrower or any Borrower Affiliate shall make a general assignment for the benefit of its creditors; or (ii) there shall be commenced against the Borrower or any Borrower Affiliate any case, proceeding or other action of a nature referred to in clause (i) above that (A) results in the entry of an order for relief or any such adjudication or appointment or (B) remains undismissed, undischarged or unbonded for a period of sixty (60) days; or (iii) there shall be commenced against the Borrower or any Borrower Affiliate any case, proceeding or other action seeking issuance of a warrant of attachment, execution, distraint or similar process against all or any substantial part of its assets that results in the entry of an order for any such relief that shall not have been vacated, discharged, or stayed or bonded pending appeal within sixty (60) days from the entry thereof; or (iv) the Borrower or any Borrower Affiliate shall take any action in furtherance of, or indicating its consent to, approval of, or acquiescence in, any of the acts set forth in clause (i), (ii), or (iii) above; or (v) the Borrower or any Borrower Affiliate shall generally not, or shall be unable to, or shall admit in writing its inability to, pay its debts as they become due; or

(h) One or more judgments or decrees shall be entered against the Borrower or any Borrower Affiliate involving for the Borrower and the Borrower Affiliates taken as a whole a liability (not paid or fully covered by insurance as to which the relevant insurance company has acknowledged coverage) of $25,000,000 or more (or in the case of a non-monetary judgment, having a Material Adverse

Effect), and all such judgments or decrees shall not have been vacated, discharged, stayed or bonded pending appeal within 30 days from the entry thereof; or

(j) Any material provision of any Loan Document after delivery thereof shall for any reason fail or cease to be valid and binding on, or enforceable against, any Loan Party party thereto, or any Loan Party shall so state in writing;

then, and in any such event, (A) if such event is an Event of Default specified in clause (i) or (ii) of paragraph (f) above, automatically the Revolving Credit Commitments shall immediately terminate and the Revolving Loans (with accrued interest thereon) and all other amounts owing under this Agreement and the other Loan Documents (including, without limitation, all amounts of Letter of Credit Obligations, whether or not the beneficiaries of the then outstanding Letters of Credit shall have presented the documents required thereunder) shall immediately become due and payable, and (B) if such event is any other Event of Default, either or both of the following actions may be taken: (i) with the consent of the Required Lenders, the Administrative Agent may, or upon the request of the Required Lenders, the Administrative Agent shall, by notice to the Borrower declare the Revolving Credit Commitments to be terminated forthwith, whereupon the Revolving Credit Commitments shall immediately terminate, and (ii) with the consent of the Required Lenders, the Administrative Agent may, or upon the request of the Required Lenders, the Administrative Agent shall, by notice to the Borrower, declare the Revolving Loans hereunder (with accrued interest thereon) and all other amounts owing under this Agreement and the other Loan Documents (including, without limitation, all amounts of Letter of Credit Obligations, whether or not the beneficiaries of the then outstanding Letters of Credit shall have presented the documents required thereunder) to be due and payable forthwith, whereupon the same shall immediately become due and payable.

8.2 Actions in Respect of Letters of Credit. At any time (i) upon the Revolving Credit Termination Date, (ii) after the Revolving Credit Termination Date when the aggregate funds on deposit in the Cash Collateral Account shall be less than 105% of the Letter of Credit Obligations, and (iii) as may be required by Section 2.8 (Mandatory Prepayments), the Borrower shall pay to the Administrative Agent in immediately available funds at the Administrative Agent’s office referred to in Section 10.8 (Notices, Etc.), for deposit in the Cash Collateral Account, the amount required that, after such payment, the aggregate funds on deposit in the Cash Collateral Account equals or exceeds 105% of the sum of all outstanding Letter of Credit Obligations. The Administrative Agent may, from time to time after funds are deposited in the Cash Collateral Account, apply funds then held in the Cash Collateral Account to the payment of any amounts, in accordance with Section 2.12(f) (Payments and Computations), as shall have become or shall become due and payable by the Borrower to the Issuers or Lenders in respect of the Letter of Credit Obligations. The Administrative Agent shall promptly give written notice of any such application; provided, however, that the failure to give such written notice shall not invalidate any such application.

(a) Each Lender and each Issuer hereby appoints Citibank as the Administrative Agent hereunder and each Lender and each Issuer authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to the Administrative Agent under such agreements and to exercise such powers as are reasonably incidental thereto. Without limiting the foregoing, each Lender and each Issuer hereby

authorizes the Administrative Agent to execute and deliver, and to perform its obligations under, each of the Loan Documents to which the Administrative Agent is a party, to exercise all rights, powers and remedies that the Administrative Agent may have under such Loan Documents.

(b) As to any matters not expressly provided for by this Agreement and the other Loan Documents (including enforcement or collection), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Lenders, and such instructions shall be binding upon all Lenders and all Issuers; provided, however, that the Administrative Agent shall not be required to take any action that (i) the Administrative Agent in good faith believes exposes it to personal liability unless the Administrative Agent receives an indemnification satisfactory to it from the Lenders and the Issuers with respect to such action or (ii) is contrary to this Agreement or applicable law. The Administrative Agent agrees to give to each Lender and each Issuer prompt notice of each notice given to it by any Loan Party pursuant to the terms of this Agreement or the other Loan Documents.

(c) In performing its functions and duties hereunder and under the other Loan Documents, the Administrative Agent is acting solely on behalf of the Lenders and the Issuers except to the limited extent provided in 2.6(b), and its duties are entirely administrative in nature. The Administrative Agent does not assume and shall not be deemed to have assumed any obligation other than as expressly set forth herein and in the other Loan Documents or any other relationship as the agent, fiduciary or trustee of or for any Lender, Issuer or holder of any other Obligation. The Administrative Agent may perform any of its duties under any Loan Document by or through its agents or employees.

9.2 Administrative Agent’s Reliance, Etc. None of the Administrative Agent, any of its Affiliates or any of their respective directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it, him, her or them under or in connection with this Agreement or the other Loan Documents, except for its, his, her or their own gross negligence or willful misconduct. Without limiting the foregoing, the Administrative Agent (a) may treat the payee of any Revolving Credit Note as its holder until such Revolving Credit Note has been assigned in accordance with Section 10.2 (Assignments and Participations), (b) may rely on the Register to the extent set forth in Section 2.6 (Evidence of Debt), (c) may consult with legal counsel (including counsel to the Borrower or any other Loan Party), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts, (d) makes no warranty or representation to any Lender or Issuer and shall not be responsible to any Lender or Issuer for any statements, warranties or representations made by or on behalf of the MLP, the Borrower or any of the Borrower’s Subsidiaries in or in connection with this Agreement or any other Loan Document, (e) shall not have any duty to ascertain or to inquire either as to the performance or observance of any term, covenant or condition of this Agreement or any other Loan Document, as to the financial condition of any Loan Party or as to the existence or possible existence of any Default or Event of Default, (f) shall not be responsible to any Lender or Issuer for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the attachment, perfection or priority of any Lien created or purported to be created under or in connection with, this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto or thereto and (g) shall incur no liability under or in respect of this Agreement or any other Loan Document by acting upon any notice, consent, certificate or other instrument or writing (which writing may be a telecopy or electronic mail) or any telephone message believed by it to be genuine and signed or sent by the proper party or parties.

(a) Each of the Lenders, the Issuers, the Borrower and the MLP agree that the Administrative Agent may, but shall not be obligated to, make the Approved Electronic Communications available to the Lenders and the Issuers by posting such Approved Electronic Communications on IntraLinks™ or a substantially similar electronic platform chosen by the Administrative Agent to be its electronic transmission system (the “Approved Electronic Platform”).

(b) Although the Approved Electronic Platform and its primary web portal are secured with generally-applicable security procedures and policies implemented or modified by the Administrative Agent from time to time (including, as of the Closing Date, a dual firewall and a User ID/Password Authorization System) and the Approved Electronic Platform is secured through a single-user-per-deal authorization method whereby each user may access the Approved Electronic Platform only on a deal-by-deal basis, each of the Lenders, the Issuer, the Borrower and the MLP acknowledges and agrees that the distribution of material through an electronic medium is not necessarily secure and that there are confidentiality and other risks associated with such distribution. In consideration for the convenience and other benefits afforded by such distribution and for the other consideration provided hereunder, the receipt and sufficiency of which is hereby acknowledged, each of the Lenders, the Issuers, the Borrower and the MLP hereby approves distribution of the Approved Electronic Communications through the Approved Electronic Platform and understands and assumes the risks of such distribution.

(c) THE APPROVED ELECTRONIC PLATFORM AND THE APPROVED ELECTRONIC COMMUNICATIONS ARE PROVIDED “AS IS” AND “AS AVAILABLE”. NONE OF THE ADMINISTRATIVE AGENT OR ANY OF ITS AFFILIATES OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR REPRESENTATIVES (THE “AGENT AFFILIATES”) WARRANT THE ACCURACY, ADEQUACY OR COMPLETENESS OF THE APPROVED ELECTRONIC COMMUNICATIONS OR THE APPROVED ELECTRONIC PLATFORM AND EACH EXPRESSLY DISCLAIMS LIABILITY FOR ERRORS OR OMISSIONS IN THE APPROVED ELECTRONIC PLATFORM AND THE APPROVED ELECTRONIC COMMUNICATIONS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT AFFILIATES IN CONNECTION WITH THE APPROVED ELECTRONIC PLATFORM OR THE APPROVED ELECTRONIC COMMUNICATIONS.

(d) Each of the Lenders, the Issuers, the Borrower and the MLP agree that the Administrative Agent may, but (except as may be required by applicable law) shall not be obligated to, store the Approved Electronic Communications on the Approved Electronic Platform in accordance with the Administrative Agent’s generally-applicable document retention procedures and policies.

9.4 The Administrative Agent Individually. With respect to its Ratable Portion, Citibank shall have and may exercise the same rights and powers hereunder and is subject to the same obligations and liabilities as and to the extent set forth herein for any other Lender. The terms “Lenders”, “Required Lenders” and any similar terms shall, unless the context clearly otherwise indicates, include, without limitation, the Administrative Agent in its individual capacity as a Lender or as one of the Required Lenders. Citibank and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of banking, trust or other business with, any Loan Party as if Citibank were not acting as the Administrative Agent.

9.5 Lender Credit Decision. Each Lender and each Issuer acknowledges that it shall, independently and without reliance upon the Administrative Agent or any other Lender, conduct its own independent investigation of the financial condition and affairs of the Borrower and each other Loan Party

in connection with the making and continuance of the Loans and with the issuance of the Letters of Credit. Each Lender and each Issuer also acknowledges that it shall, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and other Loan Documents. Except for documents expressly required by any Loan Document to be transmitted by the Administrative Agent to the Lenders or the Issuers, the Administrative Agent shall not have any duty or responsibility to provide any Lender or any Issuer with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any Loan Party or any Affiliate of any Loan Party that may come into the possession of the Administrative Agent or any Affiliate thereof or any employee or agent of any of the foregoing.

9.6 Indemnification. Each Lender agrees to indemnify the Administrative Agent and each of its Affiliates, and each of their respective directors, officers, employees, agents and advisors (to the extent not reimbursed by the Borrower), from and against such Lender’s aggregate Ratable Portion of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements (including fees, expenses and disbursements of financial and legal advisors) of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against, the Administrative Agent or any of its Affiliates, directors, officers, employees, agents and advisors in any way relating to or arising out of this Agreement or the other Loan Documents or any action taken or omitted by the Administrative Agent under this Agreement or the other Loan Documents; provided, however, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s or such Affiliate’s gross negligence or willful misconduct. Without limiting the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including fees, expenses and disbursements of financial and legal advisors) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of its rights or responsibilities under, this Agreement or the other Loan Documents, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrower or another Loan Party.

9.7 Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, selected from among the Lenders. In either case, such appointment shall be subject to the prior written approval of the Borrower (which approval may not be unreasonably withheld and shall not be required upon the occurrence and during the continuance of an Event of Default). Upon the acceptance of any appointment as Administrative Agent by a successor Administrative Agent, such successor Administrative Agent 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 under this Agreement and the other Loan Documents. Prior to any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the retiring Administrative Agent shall take such action as may be reasonably necessary to assign to the successor Administrative Agent its rights as Administrative Agent under the Loan Documents. After such resignation, the retiring Administrative Agent shall continue to have the benefit of this Section 9 as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents.

9.8 The Arrangers; the Syndication Agent; the Co-Documentation Agents. None of the Arrangers, the Syndication Agent or the Co-Documentation Agents, in their respective capacities as such, shall have any duties or responsibilities, and shall incur no liability, under this Agreement and the other Loan Documents.

(a) No amendment or waiver of any provision of this Agreement or any other Loan Document nor consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be in writing and (x) in the case of any such waiver or consent, signed by the Required Lenders (or by the Administrative Agent with the consent of the Required Lenders) and (y) in the case of any other amendment, by the Required Lenders (or by the Administrative Agent with the consent of the Required Lenders) and the Borrower, and then any such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no amendment, waiver or consent shall, unless in writing and signed by each Lender directly affected thereby, in addition to the Required Lenders (or the Administrative Agent with the consent thereof), do any of the following:

(i) waive any condition specified in Section 4.1 (Conditions to Effectiveness) or Section 4.2 (Conditions Precedent to Each Extension of Credit), except with respect to a condition based upon another provision hereof, the waiver of which requires only the concurrence of the Required Lenders and, in the case of the conditions specified in Section 4.1 (Conditions to Effectiveness), subject to the provisions of Section 4.3 (Determination of Initial Borrowing Conditions);

(ii) increase the Revolving Credit Commitment of such Lender or subject such Lender to any additional obligation;

(iii) extend the scheduled final maturity of any Revolving Loan owing to such Lender, or waive, reduce or postpone any scheduled date fixed for the payment or reduction of principal or interest of any such Loan or fees owing to such Lender (it being understood that Section 2.8 (Mandatory Prepayments) does not provide for scheduled dates fixed for payment) or for the reduction of such Lender’s Revolving Credit Commitment;

(iv) reduce, or release the Borrower from its obligations to repay, the principal amount of any Revolving Loan or Reimbursement Obligation owing to such Lender (other than by the payment or prepayment thereof);

(v) reduce the rate of interest on any Revolving Loan or Reimbursement Obligation outstanding and owing to such Lender or any fee payable hereunder to such Lender;

(vi) postpone any scheduled date fixed for payment of interest or fees owing to such Lender or waive any such payment;

(vii) change the aggregate Ratable Portions of Lenders required for any or all Lenders to take any action hereunder;

(viii) release the Borrower from its payment obligation to such Lender under this Agreement or the Revolving Credit Notes owing to such Lender (if any) or release the MLP from its obligations under the Guaranty; or

(ix) amend Section 10.7 (Sharing of Payments, Etc.), this Section 10.1 or either definition of the terms “Required Lenders” or “Ratable Portion”;

and provided, further, that (x) no amendment, waiver or consent shall, unless in writing and signed by any Special Purpose Vehicle that has been granted an option pursuant to Section 10.2(e) (Assignments and Participations), affect the grant or nature of such option or the right or duties of such Special Purpose Vehicle hereunder, and (y) no amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent in addition to the Lenders required above to take such action, affect the rights or duties of the Administrative Agent under this Agreement or the other Loan Documents; and provided, further, that the Administrative Agent may, with the consent of the Borrower, amend, modify or supplement this Agreement to cure any ambiguity, omission, defect or inconsistency, so long as such amendment, modification or supplement does not adversely affect the rights of any Lender or Issuer; and provided, further, that the Borrower and the Administrative Agent may enter into any amendment necessary to implement the terms of a Revolving Credit Commitment Increase in accordance with the terms of this Agreement without the consent of any Lender; and provided, further, that the Borrower and the Administrative Agent may enter into any amendment contemplated by Section 7.10 without the consent of any Lender.

(b) The Administrative Agent may, but shall have no obligation to, with the written concurrence of any Lender, execute amendments, modifications, waivers or consents on behalf of such Lender. Any waiver or consent shall be effective only in the specific instance and for the specific purpose for which it was given. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances.

(a) Each Lender may sell, transfer, negotiate or assign to one or more Eligible Assignees all or a portion of its rights and obligations hereunder (including all of its rights and obligations with respect to the Revolving Loans and the Letters of Credit); provided, however, that (i) if any such assignment shall be of the assigning Lender’s Revolving Credit Outstandings and Revolving Credit Commitments, such assignment shall cover the same percentage of such Lender’s Revolving Credit Outstandings and Revolving Credit Commitments, (ii) the aggregate amount being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event (if less than the assignor’s entire interest) be less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof, except, in either case, (A) with the consent of the Borrower and the Administrative Agent or (B) if such assignment is being made to a Lender or an Affiliate or Approved Fund of such Lender, and (iii) if such Eligible Assignee is not, prior to the date of such assignment, a Lender or an Affiliate or Approved Fund of a Lender, such assignment shall be subject to the prior consent of the Administrative Agent and the Borrower (which consents shall not be unreasonably withheld or delayed); and provided, further, that, notwithstanding any other provision of this Section 10.2, the consent of the Borrower shall not be required for any assignment occurring when any Event of Default shall have occurred and be continuing.

(b) The parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with any Revolving Credit Note (if the assigning Lender’s Revolving Loans are evidenced by a Revolving Credit Note) subject to such assignment. Upon the execution, delivery, acceptance and

recording in the Register of any Assignment and Acceptance and, other than in respect of assignments made pursuant to Section 2.16 (Substitution of Lenders), the receipt by the Administrative Agent from the assignee of an assignment fee in the amount of $3,500 from and after the effective date specified in such Assignment and Acceptance, (i) the assignee thereunder shall become a party hereto and, to the extent that rights and obligations under the Loan Documents have been assigned to such assignee pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender and, if such Lender were an Issuer, of such Issuer hereunder and thereunder, and (ii) the Revolving Credit Notes (if any) corresponding to the Loans assigned thereby shall be transferred to such assignee by notation in the Register and (iii) the assignor thereunder shall, to the extent that rights and obligations under this Agreement have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights (except for those surviving the payment in full of the Obligations) and be released from its obligations under the Loan Documents, other than those relating to events or circumstances occurring prior to such assignment (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under the Loan Documents, such Lender shall cease to be a party hereto).

(c) The Administrative Agent shall maintain at its address referred to in Section 10.8 (Notices, Etc.) a copy of each Assignment and Acceptance delivered to and accepted by it and shall record in the Register the names and addresses of the Lenders and Issuers and the principal amount of the Revolving Loans or Reimbursement Obligation owing to each Lender from time to time and the Revolving Credit Commitments of each Lender. Any assignment pursuant to this Section 10.2 shall not be effective until such assignment is recorded in the Register.

(d) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an assignee, the Administrative Agent shall, if such Assignment and Acceptance has been completed, (i) accept such Assignment and Acceptance, (ii) record or cause to be recorded the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower. Within five Business Days after its receipt of such notice, the Borrower, at its own expense, shall, if requested by such assignee, execute and deliver to the Administrative Agent new Revolving Credit Notes to the order of such assignee in an amount equal to the Revolving Credit Commitments and Revolving Loans assumed by it pursuant to such Assignment and Acceptance and, if the assigning Lender has surrendered any Revolving Credit Note for exchange in connection with the assignment and has retained Commitments or Revolving Loans hereunder, new Revolving Credit Notes to the order of the assigning Lender in an amount equal to the Revolving Credit Commitments and Revolving Loans retained by it hereunder. Such new Revolving Credit Notes shall be dated the same date as the surrendered Revolving Credit Notes and be in substantially the form of Exhibit E (Form of Revolving Credit Note).

(e) In addition to the other assignment rights provided in this Section 10.2, each Lender may do each of the following:

(i) grant to a Special Purpose Vehicle the option to make all or any part of any Loan that such Lender would otherwise be required to make hereunder and the exercise of such option by any such Special Purpose Vehicle and the making of Loans pursuant thereto shall satisfy (once and to the extent that such Revolving Loans are made) the obligation of such Lender to make such Revolving Loans thereunder; provided, however, that (x) nothing herein shall constitute a commitment or an offer to commit by such a Special Purpose Vehicle to make Revolving Loans hereunder and no such Special Purpose Vehicle shall be liable for any indemnity or other Obligation (other than the making of Revolving Loans for which such Special Purpose Vehicle shall have exercised an option, and then only in accordance with the relevant option agreement) and (y) such Lender’s obligations under the Loan Documents shall remain unchanged, such Lender shall remain responsible to the other parties for the performance of its obligations under

the terms of this Agreement and shall remain the holder of the Obligations for all purposes hereunder; and

(ii) assign, as collateral or otherwise, any of its rights under this Agreement, whether now owned or hereafter acquired (including rights to payments of principal or interest on the Revolving Loans), to (A) without notice to or consent of the Administrative Agent or the Borrower, any Federal Reserve Bank (pursuant to Regulation A of the Federal Reserve Board) and (B) without consent of the Administrative Agent or the Borrower, (1) any holder of, or trustee for the benefit of, the holders of such Lender’s Securities and (2) any Special Purpose Vehicle to which such Lender has granted an option pursuant to clause (i) above;

provided, however, that no such assignment or grant shall release such Lender from any of its obligations hereunder except as expressly provided in clause (i) above. Each party hereto acknowledges and agrees that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior debt of any such Special Purpose Vehicle, such party shall not institute against, or join any other Person in instituting against, any Special Purpose Vehicle that has been granted an option pursuant to this clause (e) any bankruptcy, reorganization, insolvency or liquidation proceeding (such agreement shall survive the payment in full of the Obligations). The terms of the designation of, or assignment to, such Special Purpose Vehicle shall not restrict such Lender’s ability to, or grant such Special Purpose Vehicle the right to, consent to any amendment or waiver to this Agreement or any other Loan Document or to the departure by the Borrower from any provision of this Agreement or any other Loan Document without the consent of such Special Purpose Vehicle except, as long as the Administrative Agent, the Lenders and the Issuers shall continue to, and shall be entitled to continue to, deal solely and directly with such Lender in connection with such Lender’s obligations under this Agreement, to the extent any such consent would reduce the principal amount of, or the rate of interest on, any Obligations, amend this clause (e) or postpone any scheduled date of payment of such principal or interest. Each Special Purpose Vehicle shall be entitled to the benefits of Sections 2.14 (Capital Adequacy) and 2.15 (Taxes) as if it were such Lender; provided, however, that anything herein to the contrary notwithstanding, no Borrower shall, at any time, be obligated to make under 2.14 (Capital Adequacy) or 2.15 (Taxes) to any such Special Purpose Vehicle and any such Lender any payment in excess of the amount the Borrower would have been obligated to pay to such Lender in respect of such interest if such Special Purpose Vehicle had not been assigned the rights of such Lender hereunder; and provided, further, that such Special Purpose Vehicle shall have no direct right to enforce any of the terms of this Agreement against the Borrower, the Administrative Agent or the other Lenders.

(f) Each Lender may sell participations to one or more Persons in or to all or a portion of its rights and obligations under the Loan Documents (including all its rights and obligations with respect to the Revolving Loans and Letters of Credit). The terms of such participation shall not, in any event, require the participant’s consent to any amendments, waivers or other modifications of any provision of any Loan Documents, the consent to any departure by any Loan Party therefrom, or to the exercising or refraining from exercising any powers or rights such Lender may have under or in respect of the Loan Documents (including the right to enforce the obligations of the Loan Parties), except if any such amendment, waiver or other modification or consent would reduce the amount, or postpone any date fixed for, any amount (whether of principal, interest or fees) payable to such participant under the Loan Documents, to which such participant would otherwise be entitled under such participation. In the event of the sale of any participation by any Lender, (w) such Lender’s obligations under the Loan Documents shall remain unchanged, (x) such Lender shall remain solely responsible to the other parties for the performance of such obligations, (y) such Lender shall remain the holder of such Obligations for all purposes of this Agreement and (z) the Borrower, the Administrative Agent 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. Each participant shall be entitled to the benefits of Sections 2.14

(Capital Adequacy) and 2.15 (Taxes) as if it were a Lender; provided, however, that anything herein to the contrary notwithstanding, the Borrower shall not, at any time, be obligated to make under 2.14 (Capital Adequacy) or 2.15 (Taxes) to the participants in the rights and obligations of any Lender (together with such Lender) any payment in excess of the amount the Borrower would have been obligated to pay to such Lender in respect of such interest had such participation not been sold and provided, further, that such participant in the rights and obligations of such Lender shall have no direct right to enforce any of the terms of this Agreement against the Borrower, the Administrative Agent or the other Lenders.

(g) Any Issuer may at any time assign its rights and obligations hereunder to any other Lender by an instrument in form and substance satisfactory to the Borrower, the Administrative Agent, such Issuer and such Lender, subject to the provisions of Section 2.5(c) (Evidence of Debt) relating to notations of transfer in the Register; provided, however, that each such assignment shall be subject to the prior consent of the Borrower (which consent shall not be unreasonably withheld or delayed); and provided, further, that, notwithstanding the foregoing, the consent of the Borrower shall not be required for any assignment occurring when any Event of Default shall have occurred and be continuing. If any Issuer ceases to be a Lender hereunder by virtue of any assignment made pursuant to this Section 10.2, then, as of the effective date of such cessation, such Issuer’s obligations to Issue Letters of Credit pursuant to Section 2.3 (Letters of Credit) shall terminate and such Issuer shall be an Issuer hereunder only with respect to outstanding Letters of Credit issued prior to such date.

(a) The Borrower agrees upon demand to pay, or reimburse the Administrative Agent for, all of the Administrative Agent’s reasonable internal and external audit, legal, appraisal, valuation, filing, document duplication and reproduction and investigation expenses and for all other reasonable out-of-pocket costs and expenses of every type and nature (including the reasonable fees, expenses and disbursements of the Administrative Agent’s counsel, Weil, Gotshal & Manges LLP, local legal counsel, auditors, accountants, appraisers, printers, insurance and environmental advisors, and other consultants and agents) incurred by the Administrative Agent in connection with any of the following: (i) the Administrative Agent’s audit and investigation of the Borrower and its Subsidiaries in connection with the preparation, negotiation or execution of any Loan Document or the Administrative Agent’s periodic audits of the Borrower or any of its Subsidiaries, as the case may be, (ii) the preparation, negotiation, execution or interpretation of this Agreement (including, without limitation, the satisfaction or attempted satisfaction of any condition set forth in Section 4 (Conditions Precedent)), any Loan Document or any proposal letter or commitment letter issued in connection therewith, or the making of the Loans hereunder, (iii) the ongoing administration of this Agreement and the Loans, including consultation with attorneys in connection therewith and with respect to the Administrative Agent’s rights and responsibilities hereunder and under the other Loan Documents, (iv) the protection, collection or enforcement of any Obligation or the enforcement of any Loan Document, (v) the commencement, defense or intervention in any court proceeding relating in any way to the Obligations, any Loan Party, any of the Borrower’s Subsidiaries, this Agreement or any other Loan Document, (vi) the response to, and preparation for, any subpoena or request for document production with which the Administrative Agent is served or deposition or other proceeding in which the Administrative Agent is called to testify, in each case, relating in any way to the Obligations, any Loan Party, any of the Borrower’s Subsidiaries, this Agreement or any other Loan Document or (vii) any amendment, consent, waiver, assignment, restatement, or supplement to any Loan Document or the preparation, negotiation and execution of the same; provided, however, that the Borrower shall not have any liability under subclauses (v) and (vi) of this Section 10.3(a) with respect to any costs and expenses that has resulted from the gross negligence or willful misconduct of the Administrative Agent or the breach by the Administrative Agent of its obligations under this Agreement, as determined by a court of competent jurisdiction in a final non-appealable judgment or order.

(b) The Borrower further agrees to pay or reimburse the Administrative Agent and each of the Lenders and Issuers upon demand for all out-of-pocket costs and expenses, including reasonable attorneys’ fees (including allocated costs of internal counsel and costs of settlement), incurred by the Administrative Agent, such Lenders or such Issuers in connection with any of the following: (i) in enforcing any Loan Document or Obligation or exercising or enforcing any other right or remedy available by reason of an Event of Default, (ii) in connection with any refinancing or restructuring of the credit arrangements provided hereunder in the nature of a “work-out” or in any insolvency or bankruptcy proceeding, (iii) in commencing, defending or intervening in any litigation or in filing a petition, complaint, answer, motion or other pleadings in any legal proceeding relating to the Obligations, any Loan Party, any of the Borrower’s Subsidiaries and related to or arising out of the transactions contemplated hereby or by any other Loan Document or (iv) in taking any other action in or with respect to any suit or proceeding (bankruptcy or otherwise) described in clause (i), (ii) or (iii) above; provided, however, that the Borrower shall not have any liability under subclause (iii) of this Section 10.3(b) to the Administrative Agent, any Lender or any Issuer with respect to any costs and expenses that has resulted from the gross negligence or willful misconduct of the Administrative Agent, such Lender or such Issuer, as applicable, or the breach by the Administrative Agent, such Lender or such Issuer, as applicable, of its obligations under this Agreement, as determined by a court of competent jurisdiction in a final non-appealable judgment or order.

(a) The Borrower agrees to indemnify and hold harmless each Agent, each Arranger, each Lender, each Issuer and each of their respective Affiliates, and each of the directors, officers, employees, agents, trustees, representatives, attorneys, consultants and advisors of or to any of the foregoing (including those retained in connection with the satisfaction or attempted satisfaction of any condition set forth in Section 4 (Conditions Precedent)) (each such Person being an “Indemnitee”) from and against any and all claims, damages, liabilities, obligations, losses, penalties, actions, judgments, suits, costs, disbursements and expenses, joint or several, of any kind or nature (including fees, disbursements and expenses of financial and legal advisors to any such Indemnitee) that may be imposed on, incurred by or asserted against any such Indemnitee in connection with or arising out of any investigation, litigation or proceeding, whether or not such investigation, litigation or proceeding is brought by any such Indemnitee or any of its directors, security holders or creditors or any such Indemnitee, director, security holder or creditor is a party thereto, whether direct, indirect, or consequential and whether based on any federal, state or local law or other statutory regulation, securities or commercial law or regulation, or under common law or in equity, or on contract, tort or otherwise, in any manner relating to or arising out of this Agreement, any other Loan Document, any Obligation, any Letter of Credit, or any act, event or transaction related or attendant to any thereof, or the use or intended use of the proceeds of the Revolving Loans or Letters of Credit or in connection with any investigation of any potential matter covered hereby (collectively, the “Indemnified Matters”); provided, however, that the Borrower shall not have any liability under this Section 10.4 to an Indemnitee with respect to any Indemnified Matter that has resulted from the gross negligence or willful misconduct of such Indemnitee or the breach by such Indemnitee of its obligations under this Agreement, as determined by a court of competent jurisdiction in a final non-appealable judgment or order.

(b) The Borrower shall indemnify each Agent, each Arranger, each Lender and each Issuer for, and hold the Agents, the Arrangers, the Lenders and the Issuers harmless from and against, any and all claims for brokerage commissions, fees and other compensation made against the Agents, the Arrangers, the Lenders and the Issuers for any broker, finder or consultant with respect to any agreement, arrangement or understanding made by or on behalf of any Loan Party or any of the Borrower’s Subsidiaries in connection with the transactions contemplated by this Agreement.

(c) The Borrower, at the request of any Indemnitee, shall have the obligation to defend against any investigation, litigation or proceeding, in each case contemplated in clause (a) above, and the Borrower, in any event, may participate in the defense thereof with legal counsel of the Borrower’s choice. In the event that such indemnitee requests the Borrower to defend against such investigation, litigation or proceeding, the Borrower shall promptly do so and such Indemnitee shall have the right to have legal counsel of its choice participate in such defense. No action taken by legal counsel chosen by such Indemnitee in defending against any such investigation, litigation or proceeding shall vitiate or in any way impair the Borrower’s obligation and duty hereunder to indemnify and hold harmless such Indemnitee.

(d) The Borrower agrees that any indemnification or other protection provided to any Indemnitee pursuant to this Agreement (including pursuant to this Section 10.4) or any other Loan Document shall (i) survive payment in full of the Obligations and (ii) inure to the benefit of any Person that was at any time an Indemnitee under this Agreement or any other Loan Document.

(a) The Borrower agrees that no Indemnitee shall have any liability (whether in contract, tort or otherwise) to any Loan Party or any of their respective Subsidiaries or any of their respective equity holders or creditors for or in connection with the transactions contemplated hereby and in the other Loan Documents, except to the extent such liability is determined in a final non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnitee’s gross negligence or willful misconduct or the breach by such Indemnitee of its obligations under this Agreement. In no event, however, shall any Indemnitee be liable on any theory of liability for any special, indirect, consequential or punitive damages (including, without limitation, any loss of profits, business or anticipated savings). The Borrower hereby waives, releases and agrees (each for itself and on behalf of its Subsidiaries and the MLP) not to sue upon any such claim for any special, indirect, consequential or punitive damages, whether or not accrued and whether or not known or suspected to exist in its favor.

(b) IN NO EVENT SHALL ANY AGENT AFFILIATE HAVE ANY LIABILITY TO ANY LOAN PARTY, LENDER, ISSUER OR ANY OTHER PERSON FOR DAMAGES OF ANY KIND, INCLUDING DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT OR CONTRACT OR OTHERWISE) ARISING OUT OF ANY LOAN PARTY OR ANY AGENT AFFILIATE’S TRANSMISSION OF APPROVED ELECTRONIC COMMUNICATIONS THROUGH THE INTERNET OR ANY USE OF THE APPROVED ELECTRONIC PLATFORM, EXCEPT TO THE EXTENT SUCH LIABILITY OF ANY AGENT AFFILIATE IS FOUND IN A FINAL NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED PRIMARILY FORM SUCH AGENT AFFILIATE’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

10.6 Right of Set-off. Upon the occurrence and during the continuance of any Event of Default each Lender and each Affiliate of a Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other Indebtedness at any time owing by such Lender or its Affiliates to or for the credit or the account of the Borrower against any and all of the Obligations now or hereafter existing whether or not such Lender shall have made any demand under this Agreement or any other Loan Document and even though such Obligations may be unmatured. Each Lender agrees promptly to notify the Borrower after any such set-off and application made by such Lender or its Affiliates; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender under this Section 10.6 are in addition to the other rights and remedies (including other rights of set-off) that such Lender may have.

(a) If any Lender (directly or through an Affiliate thereof) obtains any payment (whether voluntary, involuntary, through the exercise of any right of set-off (including pursuant to Section 10.6 (Right of Set-off)) or otherwise) of the Loans owing to it, any interest thereon, fees in respect thereof or amounts due pursuant to Section 10.3 (Costs and Expenses) or 10.4 Indemnities) (other than payments pursuant to Section 2.13 (Special Provisions Governing Eurodollar Rate Loans), 2.14 (Capital Adequacy) or 2.15 (Taxes) (in each case, whether voluntary, involuntary, through the exercise of any right of set-off (including pursuant to Section 10.6 (Right of Set-off)) or otherwise) in excess of its Ratable Portion of all payments of such Obligations obtained by all the Lenders, such Lender (a “Purchasing Lender”) shall forthwith purchase from the other Lenders (each, a “Selling Lender”) such participations in their Loans or other Obligations as shall be necessary to cause such Purchasing Lender to share the excess payment ratably with each of them.

(b) If all or any portion of any payment received by a Purchasing Lender is thereafter recovered from such Purchasing Lender, such purchase from each Selling Lender shall be rescinded and such Selling Lender shall repay to the Purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Selling Lender’s ratable share (according to the proportion of (i) the amount of such Selling Lender’s required repayment in relation to (ii) the total amount so recovered from the Purchasing Lender) of any interest or other amount paid or payable by the Purchasing Lender in respect of the total amount so recovered.

(c) The Borrower agrees that any Purchasing Lender so purchasing a participation from a Selling Lender pursuant to this Section 10.7 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

(a) Addresses for Notices. All notices, demands, requests, consents and other communications provided for in this Agreement shall be given in writing, or by any telecommunication device capable of creating a written record (including electronic mail), and addressed to the party to be notified as follows:

(ii) if to any Lender, at its Domestic Lending Office specified opposite its name on Schedule II (Applicable Lending Offices) or on the signature page of any applicable Assignment and Acceptance;

(iii) if to any Issuer, at the address set forth under its name on Schedule II (Applicable Lending Offices) or on the signature page of any applicable Assignment and Acceptance; and

or at such other address as shall be notified in writing (x) in the case of the Borrower and the Administrative Agent, to the other parties and (y) in the case of all other parties, to the Borrower and the Administrative Agent.

(b) Effectiveness of Notices. All notices, demands, requests, consents and other communications described in Section 10.8(a) above shall be effective (i) if delivered by hand, including any overnight courier service, upon personal delivery, (ii) if delivered by mail, when deposited in the mails, (iii) if delivered by posting to an Approved Electronic Platform (to the extent permitted by Section 9.3 to be delivered thereunder), an Internet website or a similar telecommunication device requiring a user prior access to such Approved Electronic Platform, website or other device (to the extent permitted by Section 9.3 to be delivered thereunder), when such notice, demand, request, consent and other communication shall have been made generally available on such Approved Electronic Platform, Internet website or similar device to the class of Person being notified (regardless of whether any such Person must accomplish, and whether or not any such Person shall have accomplished, any action prior to obtaining access to such items, including registration, disclosure of contact information, compliance with a standard user agreement or undertaking a duty of confidentiality) and such Person has been notified that such communication has been posted to the Approved Electronic Platform and (iv) if delivered by electronic mail or any other telecommunications device, when transmitted to an electronic mail address

(or by another means of electronic delivery) as provided in clause 10.8 above; provided, however, that notices and communications to the Administrative Agent pursuant to Section 2 (Amount and Terms of Commitments) or Section 9 (The Agents) shall not be effective until received by the Administrative Agent.

(c) Use of Electronic Platform. Notwithstanding Section 10.8(a) and (b) above (unless the Administrative Agent requests that the provisions of Section 10.8(a) and (b) above be followed) and any other provision in this Agreement or any other Loan Document providing for the delivery of any Approved Electronic Communication by any other means the Loan Parties shall deliver all Approved Electronic Communications to the Administrative Agent by properly transmitting such Approved Electronic Communications in an electronic/soft medium in a format acceptable to the Administrative Agent to oploanswebadmin@citigroup.com or such other electronic mail address (or similar means of electronic delivery) as the Administrative Agent may notify the Borrower. Nothing in this clause (c) shall prejudice the right of the Administrative Agent, any Lender or any Issuer to deliver any Approved Electronic Communication to any Loan Party in any manner authorized in this Agreement or to request that the Borrower effect delivery in such manner.

10.9 No Waiver; Remedies. No failure on the part of any Lender, any Issuer or the Administrative Agent to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

10.10 Binding Effect. This Agreement shall become effective when it shall have been executed by the Borrower and the Administrative Agent and when the Administrative Agent shall have been notified by each Lender and Issuer that such Lender or Issuer has executed it and thereafter shall be binding upon and inure solely to the benefit of the Borrower, the Administrative Agent and each Lender and Issuer and, in each case, their respective successors and assigns; provided, however, that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lenders.

10.11 Governing Law. This Agreement and the rights and obligations of the parties hereto shall be governed by, and construed and interpreted in accordance with, the law of the State of New York.

The Borrower agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

10.13 Waiver of Jury Trial. EACH OF THE AGENTS, THE LENDERS, THE ISSUERS AND THE BORROWER IRREVOCABLY WAIVES TRIAL BY JURY IN ANY ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT.
