The Borrower may from time to time prepay, without penalty or premium, all outstanding Base Rate Advances, or any portion thereof in a minimum aggregate amount of $1,000,000 or any integral multiple of $500,000 in excess thereof, on any Business Day upon notice to the Agent by no later than 11:00 a.m. on the date of such prepayment. The Borrower may at any time prepay, without penalty or premium, all outstanding Swing Line Loans, or any portion thereof, on any Business Day upon notice to the Agent and the Swing Line Lender by 11:00 a.m. on the date of such repayment. The Borrower may from time to time prepay, subject to the payment of any amounts required by Section 3.4 but without penalty or premium, all outstanding Eurodollar Advances, or any portion thereof in a minimum aggregate amount of $5,000,000 or any integral multiple of $1,000,000 in excess thereof upon at least two (2) Business Days’ prior notice to the Agent (or such shorter period as may be acceptable to the Agent).

(d) in the case of a Eurodollar Advance, the Interest Period applicable thereto.

Not later than 1:00 p.m. on each Borrowing Date, each Lender (subject to the satisfaction of the applicable conditions precedent set forth in Article IV) shall make available its Revolving Loan or Revolving Loans in funds immediately available to the Agent at its address specified pursuant to Section 9.20. The Agent will promptly make the funds so received from the Lenders available to the Borrower at the Agent’s aforesaid address. If the Borrower requests a Eurodollar Advance but fails to specify an Interest Period therefor, such Eurodollar Advance will be deemed to have an Interest Period of one month.

Section 2.9. Conversion and Continuation of Outstanding Advances. Base Rate Advances shall continue as Base Rate Advances unless and until such Base Rate Advances are converted into Eurodollar Advances pursuant to this Section 2.9 or are repaid in accordance with Section 2.7. Each Eurodollar Advance shall continue as a Eurodollar Advance until the end of the then applicable Interest Period therefor, at which time such Eurodollar Advance shall be automatically converted into a Base Rate Advance unless (x) such Eurodollar Advance is or was repaid in accordance with Section 2.7 or (y) the Borrower shall have given the Agent a Conversion/Continuation Notice requesting that, at the end of such Interest Period, such Eurodollar Advance continue as a Eurodollar Advance for the same or another Interest Period. Subject to the terms of Section 2.6, the Borrower may elect from time to time to convert all or any part of a Base Rate Advance into a Eurodollar Advance. The Borrower shall give the Agent irrevocable notice (a “Conversion/Continuation Notice”) in accordance with Section 2.14, which, when in writing, shall be in substantially the form attached hereto as Exhibit H, of each conversion of a Base Rate Advance into a Eurodollar Advance or continuation of a Eurodollar Advance not later than 11:00 a.m. on the third Business Day prior to the date of the requested conversion or continuation, specifying:

(b) the aggregate amount and Type of the Advance which is to be converted or continued; and

If the Borrower requests a conversion to, or continuation of a Eurodollar Advance but fails to specify an Interest Period therefor, such Eurodollar Advance will be deemed to have an Interest Period of one month.

Section 2.10. Changes in Interest Rate, etc. Each Base Rate Advance shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Advance is made or is automatically converted from a Eurodollar Advance into a Base Rate Advance pursuant to Section 2.9, to but excluding the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.9, at a rate per annum equal to the Base Rate for such day. Each Swing Line Loan shall bear interest on the outstanding principal amount thereof, for each day from and including the day such Swing Line Loan is made to but excluding the date it is paid, at a rate per annum equal to the Swing Line Rate for such day. Changes in the rate of

interest on that portion of any Advance maintained as a Base Rate Advance or on a Swing Line Loan will take effect simultaneously with each change in the Alternate Base Rate or Eurodollar Rate, respectively. Each Eurodollar Advance shall bear interest on the outstanding principal amount thereof from and including the first day of the Interest Period applicable thereto to (but not including) the last day of such Interest Period at the Eurodollar Rate for such Interest Period, as determined by the Agent. No Interest Period may end after the Scheduled Revolving Credit Maturity Date. The Borrower shall select Interest Periods so that it is not necessary to repay any portion of a Eurodollar Advance prior to the last day of the applicable Interest Period in order to make a mandatory prepayment required pursuant to the last sentence of Section 2.2.

Section 2.11. Rates Applicable After Event of Default. Notwithstanding anything to the contrary contained in Section 2.8, 2.9 or 2.10, upon the occurrence and during the continuance of an Event of Default, the Required Lenders may, at their option, by notice to the Borrower, declare that no Advance may be made as, converted into or continued as a Eurodollar Advance. If all or a portion of (a) the principal amount of any Loan or any Reimbursement Obligation, (b) any interest payable thereon, or (c) any fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest, payable from time to time on demand, at a rate per annum equal to the Default Rate, in each case from the date of such non-payment until such amount is paid in full.

Section 2.12. Method of Payment. All payments of the Obligations hereunder shall be made, without setoff or counterclaim, in immediately available funds to the Agent at the Agent’s address specified pursuant to Section 9.20, or at any other Lending Installation of the Agent specified in writing by the Agent to the Borrower, by noon on the date when due and shall be applied ratably (except in the case of (a) Reimbursement Obligations for which an LC Issuer has not been fully indemnified by the Lenders, (b) Swing Line Loans or (c) as otherwise specifically required hereunder) by the Agent among the Lenders. Each payment delivered to the Agent for the account of any Lender shall be delivered promptly by the Agent to such Lender in the same type of funds that the Agent received at such Lender’s address specified pursuant to Section 9.20 or at any Lending Installation specified in a notice received by the Agent from such Lender.

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

(b) The Agent shall also maintain accounts in which it will record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period (in the case of a Eurodollar Advance) with respect thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder, (iii) the original face amount of each Facility LC and the amount of LC Obligations outstanding at any time, and (iv) the amount of any sum received by the Agent hereunder from the Borrower and each Lender’s share thereof.

(c) The entries maintained in the accounts maintained pursuant to paragraphs (a) and (b) above shall be prima facie evidence of the existence and amounts of the Obligations therein recorded absent manifest error; provided, that the failure of the Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

(d) Any Lender may request that its Loans be evidenced by a promissory note, or in the case of the Swing Line Lender, promissory notes representing its Revolving Loans and Swing Line Loans, respectively, in substantially the form of Exhibit D with applicable changes for notes evidencing Swing Line Loans (a “Note”). In such event, the Borrower shall prepare, execute and deliver to such Lender such Note payable to such Lender. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (prior to any assignment pursuant to Section 12.3) be represented by one or more Notes payable to the payee named therein, except to the extent that any such Lender subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in paragraphs (a) and (b) above.

Section 2.14. Telephonic Notices. The Borrower hereby authorizes the Lenders and the Agent to extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds based on telephonic notices (confirmed promptly in writing) made by any person or persons the Agent or any Lender in good faith believes to be acting on behalf of the Borrower. The Borrower agrees to deliver promptly to the Agent a written confirmation of each telephonic notice, signed by an Authorized Officer. If the written confirmation differs in any material respect from the action taken by the Agent and the Lenders, the records of the Agent and the Lenders shall govern absent manifest error.

Section 2.15. Interest Payment Dates; Interest and Fee Basis. Interest accrued on each Base Rate Advance and Swing Line Loan shall be payable in arrears on each Payment Date, commencing with the first such date to occur after the Closing Date, on any date on which the Base Rate Advance or Swing Line Loan is prepaid, whether due to acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance shall be payable on the last day of its applicable Interest Period, on any date on which the Eurodollar Advance is prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period. Interest on Base Rate Advances when the Alternate Base Rate is determined by the Prime Rate shall be calculated for actual days elapsed on the basis of a 365, or when appropriate 366, day year. All other computations of interest, LC Fees and all other fees shall be calculated for actual days elapsed on the basis of a 360-day year. Interest shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if payment is received prior to noon at the place of payment. If any payment of principal of or interest on an Advance, any fees or any other amounts payable to the Agent or any Lender hereunder shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest and fees in connection with such payment.

Section 2.16. Notification of Advances, Interest Rates, Prepayments and Commitment Reductions. Promptly after receipt thereof, the Agent will notify each Lender of the contents of each Aggregate Commitment reduction notice, Borrowing Notice, Swing Line Borrowing Notice, Conversion/Continuation Notice, and prepayment notice received by it hereunder. The applicable LC Issuer shall notify the Agent promptly after the issuance of a Facility LC, and the Agent will notify each Lender of such issuance. The Agent will notify the Borrower and each Lender of the interest rate applicable to each Eurodollar Advance promptly upon determination of such interest rate and will give the Borrower and each Lender prompt notice of each change in the Alternate Base Rate.

Section 2.17. Lending Installations. Each Lender may book its Loans and its participation in any LC Obligations and Swing Line Loans, and each LC Issuer may book its Facility LCs, at any Lending Installation selected by such Lender or LC Issuer, as applicable, and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Loans, Facility LCs, participations in LC Obligations and Swing Line Loans and any Notes issued hereunder shall be deemed held by each Lender or LC Issuer, as applicable, for the benefit of any such Lending Installation. Each Lender and LC Issuer may, by written notice to the Agent and the Borrower in accordance with Section 9.20, designate replacement or additional Lending Installations through which Loans will be made by it or Facility LCs will be issued by it and for whose account Loan payments or payments with respect to Facility LCs are to be made.

Section 2.18. Non-Receipt of Funds by the Agent. Unless the Borrower notifies the Agent prior to the time which it is scheduled to make payment to the Agent of a payment of principal, interest or fees to the Agent for the account of the Lenders, that it does not intend to make such payment, the Agent may assume that such payment has been made. The Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If the Borrower has not in fact made such payment to the Agent, the recipient of such payment shall, on demand by the Agent, repay to the Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate per annum equal to the interest rate applicable to the relevant Loan.

Section 2.19. Replacement of Lender. If (w) any Lender requests compensation under Section 3.1, or if the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.5 and, in each case, such Lender has declined or is unable to promptly designate a different Lending Installation in accordance with Section 3.7 which would eliminate any further claims for such indemnity, compensation or payment, (x) any Lender is a Defaulting Lender or a Non-Consenting Lender, (y) any Lender’s obligation to make or to convert or continue outstanding Loans or Advances as Eurodollar Loans or Eurodollar Advances has been suspended pursuant to Section 3.3, and, in each such case, such Lender has declined or is unable to promptly designate a different Lending Installation in accordance with Section 3.7 which would eliminate any further suspension or (z) in addition to the rights of the Borrower under Section 2.21, any Lender is a Non-Extending Lender and the Required Lenders have approved the related Extension Request, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Agent, require such Lender to assign and delegate (provided that the failure by any such Lender that is a Defaulting Lender to execute an Assignment and Assumption Agreement shall

not render such assignment invalid), without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 12.3), all of its interests, rights (other than its existing rights to payments pursuant to Section 3.1 or 3.5) and obligations under this Agreement and the related Loan Documents (other than, if such Lender is an LC Issuer that has issued any outstanding Facility LCs at such time, its rights and obligations as an LC Issuer with respect to such Facility LCs) to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that:

(a) the Borrower shall have received (i) the prior written consent of the Agent, the Swing Line Lender, and each LC Issuer with respect to any assignee that is not already a Lender or an affiliate of a Lender hereunder, which consent shall not unreasonably be withheld, conditioned or delayed, (ii) the consent of such assignee to the assignment, (iii) in the case of any assignment resulting from a Lender becoming a Non-Consenting Lender, the consent of the applicable assignee to the applicable amendment, waiver or consent and (iv) in the case of an assignment resulting from a Lender becoming a Non-Extending Lender, the consent of the applicable assignee to the applicable Extension Request;

(b) the Agent shall have received the assignment fee specified in Section 12.3(c) unless (i) waived by the Agent or (ii) the assignee is another Lender;

(c) such Lender shall have received payment of an amount equal to its funded and outstanding principal balance of its Outstanding Credit Exposure, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including (other than with respect to any Defaulting Lender) any amounts under Section 3.4) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

(d) in the case of any such assignment resulting from (i) a claim for compensation under Section 3.1 or payments required to be made pursuant to Section 3.5, such assignment will result in a reduction in such compensation or payments thereafter or (ii) a suspension under Section 3.3, such assignment shall be made to a Lender or Eligible Assignee which is not subject to such a suspension; and

A Lender shall not be required to make any such assignment if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment cease to apply.

(a) Issuance. Each LC Issuer hereby agrees, on the terms and conditions set forth in this Agreement, to issue standby letters of credit for any lawful purpose (each such letter of credit, a “Facility LC”) denominated in Dollars and to renew, extend, increase, decrease or otherwise modify each Facility LC (“Modify,” and each such action, a “Modification”), from time to time from and including the Closing Date and prior to the Revolving Credit Maturity Date upon the request of the Borrower; provided that immediately after each such Facility LC is issued or Modified, (i) the LC Obligations shall not exceed the LC Commitment, (ii) the

Aggregate Outstanding Credit Exposure shall not exceed the Aggregate Commitment and (iii) the aggregate amount of LC Obligations of any LC Issuer at any time shall not exceed such LC Issuer’s LC Issuer Sublimit, unless otherwise expressly agreed by such LC Issuer. On the Closing Date, the letter of credit heretofore issued by Bank of America, N.A. described on Schedule 1.1 shall automatically, and without any further action by any party, constitute a Facility LC issued pursuant to this Section 2.20, and Bank of America, N.A., solely for the purpose of maintaining such letter of credit, shall constitute an LC Issuer for so long as (and only for so long as) such letter of credit remains outstanding.

(b) Expiration of Facility LCs. In the event that the expiry date of a Facility LC is later than five (5) Business Days prior to the Scheduled Revolving Credit Maturity Date, prior to such date that is five (5) Business Days prior to the Scheduled Revolving Credit Maturity Date, the Borrower shall deliver to the Agent cash, to be held by the Agent, for the benefit of the LC Issuers and the Lenders, in the Cash Collateral Account as security for the LC Obligations in respect of subsequent drawings under such Facility LC in an amount equal to 100% of the face amount of such outstanding Facility LC plus related fees and expenses with respect to such outstanding Facility LC over its remaining term (which cash will be invested pursuant to the requirements of Section 2.20(j)), pursuant to documentation in form and substance reasonably satisfactory to the Agent and the applicable LC Issuer. Any Facility LC with a one-year tenor may provide for the renewal thereof for additional one-year periods. If any Facility LC contains a provision pursuant to which it is deemed to be automatically renewed unless notice of termination is given by the applicable LC Issuer with respect to such Facility LC, such LC Issuer shall timely give notice of termination if (A) as of the close of business on the seventeenth (17^th) day prior to the last day upon which such LC Issuer’s notice of termination may be given to the beneficiaries of such Facility LC, such LC Issuer has received a notice of termination from the Borrower or a notice from the Agent that the conditions to issuance of such Facility LC have not been satisfied or (B) the renewed Facility LC would extend beyond the date that is five (5) Business Days prior to the Scheduled Revolving Credit Maturity Date (unless such Facility LC is Cash Collateralized per the terms of this Section 2.20(b)).

(c) Participations. Upon (i) the issuance by the applicable LC Issuer of each Facility LC in accordance with this Section 2.20 and (ii) the Modification of each Facility LC increasing or decreasing the face amount thereof in accordance with this Section 2.20, the applicable LC Issuer shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably sold to each Lender, and each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from such LC Issuer, a participation in such Facility LC (and each Modification thereof) and the related LC Obligations in proportion to such Lender’s Pro Rata Share.

(d) Procedures for Issuing or Modifying a Facility LC. Subject to Section 2.20(a) and (b), (i) to request the issuance of a Facility LC, the Borrower shall deliver an LC Application to the applicable LC Issuer prior to 11:00 a.m. at least three (3) Business Days prior to the proposed date of issuance thereof and (ii) to request a Modification of a Facility LC, the Borrower shall deliver notice thereof to the applicable LC Issuer prior to 11:00 a.m. at least three (3) Business Days prior to the proposed date of Modification, identifying the Facility LC to be Modified and specifying the name and address of the beneficiary, the proposed date of Modification, the expiry date of such Modified Facility LC and such other information as shall

be reasonably requested by such LC Issuer to Modify such Facility LC, accompanied by the written consent of the beneficiary thereto to the extent such consent is required pursuant to the terms of such Facility LC. Upon the applicable LC Issuer’s receipt of an LC Application or a notice of Modification, such LC Issuer shall promptly notify the Agent, and, in the case of an issuance of a Facility LC only, the Agent shall then promptly notify each Lender of the contents thereof and of the amount of such Lender’s participation in such Facility LC. Subject to each LC Issuer’s agreements set forth herein, each Facility LC issued by such LC Issuer shall be in a form reasonably satisfactory to such LC Issuer. In the event of any conflict or inconsistency between the terms of this Agreement and the terms of any LC Application or any other agreement entered into by the Borrower with an LC Issuer relating to any Facility LC, the terms of this Agreement shall control.

(e) LC Fees. The Borrower shall pay to the Agent, for the account of the Lenders (subject, with respect to any Defaulting Lender, to the limitations set forth in Section 2.24(a)(iii)) ratably in accordance with their respective Pro Rata Shares, with respect to each Facility LC, a letter of credit fee at a per annum rate equal to the Applicable Margin for Eurodollar Loans in effect from time to time on the average daily undrawn face amount under such Facility LC, such fee to be payable in arrears on each Payment Date (the “LC Participation Fee”). The Borrower shall also pay to each LC Issuer for its own account (i) a fronting fee at a per annum rate equal to 0.15% on the average daily undrawn face amount under each Facility LC issued by such LC Issuer, such fee to be payable in arrears on each Payment Date, and (ii) normal and customary charges, costs and reasonable expenses incurred or charged by such LC Issuer in connection with the issuance or Modification of and draws under the Facility LCs issued by such LC Issuer in accordance with such LC Issuer’s standard schedule for such charges as in effect from time to time. Each fee described in this Section 2.20(e) shall constitute an “LC Fee”.

(f) Administration; Reimbursement by Lenders. Upon receipt from the beneficiary of any Facility LC of any demand for payment under such Facility LC, the applicable LC Issuer shall notify the Agent and the Agent shall promptly notify the Borrower and each other Lender as to the amount to be paid by the LC Issuer as a result of such demand and the proposed payment date (the “LC Payment Date”). The responsibility of each LC Issuer to the Borrower and each Lender shall be only to determine that the documents (including each demand for payment) delivered under each Facility LC in connection with such presentment shall be in strict conformity with the terms and conditions of such Facility LC. Each LC Issuer shall endeavor to exercise the same care in the issuance and administration of the Facility LCs as it does with respect to letters of credit in which no participations are granted, it being understood that each Lender shall be unconditionally and irrevocably liable without regard to the occurrence of any Event of Default or any condition precedent whatsoever, to reimburse such LC Issuer on demand without offset of any kind for (i) such Lender’s Pro Rata Share of the amount of each payment made by such LC Issuer under each Facility LC with respect to any drawing or other demand for payment made by a beneficiary thereunder prior to the Scheduled Revolving Credit Maturity Date (it being understood and agreed that no Lender shall have any obligation to reimburse any LC Issuer with respect to any drawing or other demand for payment under any Facility LC made after the Scheduled Revolving Credit Maturity Date, regardless of whether the Borrower has complied with any obligation to deliver Cash Collateral in respect of such Facility LC pursuant to the terms of this Agreement), to the extent such amount is not reimbursed by the

Borrower pursuant to Section 2.20(g) below, plus (ii) interest on the foregoing amount to be reimbursed by such Lender, from and including the date such payment is made by such LC Issuer to the date on which such Lender pays the amount to be reimbursed by it, at a rate of interest per annum equal to the Federal Funds Effective Rate for the first three (3) days and, thereafter, at a rate of interest equal to the rate applicable to Base Rate Advances.

(g) Reimbursement by Borrower. The Borrower shall be irrevocably and unconditionally obligated to reimburse each LC Issuer on the applicable LC Payment Date (if notified of such drawing prior to 1:00 p.m. on such date, otherwise on the next Business Day following receipt of such notice) for any amounts to be paid by such LC Issuer upon any drawing under any Facility LC, without presentment, demand (other than as set forth above), protest or other formalities of any kind; provided that to the extent the Borrower does not reimburse the applicable LC Issuer on the applicable LC Payment Date (or the next Business Day, as applicable), then the Borrower shall be deemed to have requested that the Swing Line Lender make a Swing Line Loan on such date; and provided further that neither the Borrower nor any Lender shall hereby be precluded from asserting any claim for direct (but not consequential, special, indirect or punitive) damages suffered by the Borrower or such Lender to the extent, but only to the extent, caused by (i) such LC Issuer’s gross negligence, bad faith or willful misconduct, as determined by a court of competent jurisdiction by final non-appealable judgment or (ii) such LC Issuer’s failure to pay under any Facility LC issued by it after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. Each LC Issuer will pay to each Lender (other than any Defaulting Lender to the extent such Defaulting Lender has not provided Cash Collateral for the LC Issuers’ Fronting Exposure in respect thereof) ratably in accordance with its Pro Rata Share all amounts received by it from the Borrower for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Facility LC issued by such LC Issuer, but only to the extent such Lender has made payment to such LC Issuer in respect of such Facility LC pursuant to Section 2.20(f). Subject to the terms and conditions of this Agreement (including the submission of a Borrowing Notice in compliance with Section 2.8 and the satisfaction of the applicable conditions precedent set forth in Article IV), the Borrower may request an Advance hereunder for the purpose of satisfying any Reimbursement Obligation.

(i) The Borrower’s obligations under this Section 2.20 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the Borrower may have or have had against any LC Issuer, any Lender or any beneficiary of a Facility LC.

(ii) The Borrower further agrees with the LC Issuers and the Lenders that the LC Issuers and the Lenders shall not be responsible for, and the Borrower’s Reimbursement Obligation in respect of any Facility LC shall not be affected by, among other things, (A) the validity or genuineness of documents, instruments or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, insufficient, fraudulent or forged, (B) any dispute between or among the Borrower, any of its Affiliates, the beneficiary of any Facility LC or any financing institution or other party to whom any Facility LC may be transferred or any claims or

defenses whatsoever of the Borrower or of any of its Affiliates against the beneficiary of any Facility LC or any such transferee, (C) the existence of any claims, set-off, defense or other right whatsoever of the Borrower against any beneficiary of such Facility LC or any such transferee, (D) any lack of validity or enforceability of any Facility LC or this Agreement, or any term of provision therein or herein, (E) payment by the LC Issuer under a Facility LC against presentation of a draft or other document that does not comply with the terms of such Facility LC, or (F) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder or under any Facility LC.

(iii) No LC Issuer shall be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Facility LC.

(iv) The Borrower agrees that any action taken or omitted by any LC Issuer or Lender under or in connection with each Facility LC and the related drafts and documents, if done without gross negligence, willful misconduct or bad faith, as determined by a final, non-appealable judgment of a court of competent jurisdiction, shall be binding upon the Borrower and shall not result in any liability of such LC Issuer or Lender to the Borrower.

(v) Nothing in this Section 2.20(h) is intended to limit the right of the Borrower to make a claim against the applicable LC Issuer for damages as contemplated by the second proviso to the first sentence of Section 2.20(g).

(i) Actions of the LC Issuers. Each LC Issuer shall be entitled to rely, and shall be fully protected in relying, upon any Facility LC, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document reasonably believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by such LC Issuer. In the absence of (x) willful misconduct, gross negligence or bad faith of the applicable LC Issuer (as determined by a final, non-appealable judgment of a court of competent jurisdiction) in determining whether a request presented under any Facility LC complied with the terms of such Facility LC or (y) the applicable LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC, such LC Issuer shall be fully (a) justified in failing or refusing to take any action under this Agreement unless it shall first have received such advice or concurrence of the Required Lenders as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action, and (b) protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Required Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Lenders and any future holders of a participation in any Facility LC.

(i) Establishment of Cash Collateral Account. If the Borrower is required to provide Cash Collateral under the terms of this Agreement, the Borrower and the Agent shall establish the Cash Collateral Account, and the Borrower shall execute any documents and agreements that the Agent reasonably requests in connection therewith to establish the Cash Collateral Account, including, if so requested, an assignment of deposit accounts in form and substance reasonably satisfactory to the Agent and the Borrower. The Borrower hereby pledges, assigns and grants to the Agent, on behalf of and for the ratable benefit of the Lenders (including the LC Issuers), and agrees to maintain, a first priority security interest in the Cash Collateral Account and all of the Borrower’s right, title and interest in and to all Cash Collateral which may from time to time be on deposit in the Cash Collateral Account, and all proceeds thereof, to secure the prompt and complete payment and performance of the Obligations. If at any time the Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Agent and the LC Issuers as herein provided, or that the total amount of such Cash Collateral is less than the amount required to be deposited under this Agreement, the Borrower will, promptly upon demand by the Agent, pay or provide to the Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by any Defaulting Lender).

(ii) Application of Funds. Moneys in the Cash Collateral Account held in respect of LC Obligations arising from a particular Facility LC shall be applied by the Agent to reimburse the LC Issuer that issued such Facility LC for Reimbursement Obligations that arise in connection with such Facility LC for which it has not been reimbursed and, to the extent not so applied, and subject to clause (iii) below, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the Fronting Exposure with respect to such Facility LC at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of the applicable LC Issuer), be applied to satisfy other Obligations of the Borrower.

(iii) Release of Funds. If no Event of Default has occurred and is continuing, within three Business Days of the Borrower’s written request, the Agent shall release to the Borrower any and all funds held in the Cash Collateral Account above the aggregate amounts then expressly required, if any, to be deposited and held as Cash Collateral under all relevant provisions of this Agreement. In addition, after all of the Obligations have been paid in full (other than contingent indemnification obligations), the Aggregate Commitment has been terminated and all Facility LCs have been terminated or expired, any funds remaining in the Cash Collateral Account shall be returned by the Agent to the Borrower or paid to whomever may be legally entitled thereto at such time.

(iv) Administration of Cash Collateral Account. The Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over the Cash Collateral Account. If and when required by the Borrower, the Agent shall invest and reinvest funds held in the Cash Collateral Account from time to time in cash equivalents specified from time to time by the Borrower and reasonably acceptable to the Agent. Interest or profits, if any, on such investments shall accumulate in such account. The Agent shall exercise reasonable care in the custody and preservation of any funds held in the Cash Collateral Account and shall be deemed to have exercised such care if

such funds are accorded treatment substantially equivalent to that which the Agent accords its own property, it being understood that the Agent shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds.

(k) Rights as a Lender. In its capacity as a Lender, each LC Issuer shall have the same rights and obligations as any other Lender.

(l) Replacement of an LC Issuer. Any LC Issuer may be replaced at any time by written agreement among the Borrower, the Agent, the replaced LC Issuer and the successor LC Issuer. The Agent shall notify the Lenders of any such replacement of an LC Issuer. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced LC Issuer pursuant to Section 2.20(e). From and after the effective date of any such replacement, (A) the successor LC Issuer shall have all the rights and obligations of an LC Issuer under this Agreement with respect to Facility LCs to be issued by it thereafter and (B) references herein to the term “LC Issuer” shall be deemed to refer to such successor or to any previous LC Issuer, or to such successor and all previous LC Issuers, as the context shall require. After the replacement of an LC Issuer hereunder, the replaced LC Issuer shall remain a party hereto and shall continue to have all the rights and obligations of an LC Issuer under this Agreement with respect to Facility LCs issued by it prior to such replacement, but shall not be required to issue additional Facility LCs.

(m) Defaulting Lenders. At any time that there shall exist a Defaulting Lender, within one (1) Business Day following the written request of the Agent or any LC Issuer (with a copy to the Agent) the Borrower shall Cash Collateralize the LC Issuers’ Fronting Exposure with respect to such Defaulting Lender (determined after giving effect to the reallocation provided in Section 2.24(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount equal to such Fronting Exposure or such higher amount agreed to by the Borrower.

(i) Defaulting Lender’s Grant of Security Interest. To the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to the Agent, for the benefit of the LC Issuers, and agrees to maintain, a first priority security interest in all such Cash Collateral as security for such Defaulting Lender’s obligation to fund participations in respect of LC Obligations, to be applied pursuant to clause (ii) below.

(ii) Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this Section 2.20(m) or Section 2.24 in respect of Facility LCs shall be applied to the satisfaction of the Defaulting Lender’s unreallocated obligation to fund participations in respect of LC Obligations (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(iii) Termination of Requirement. Cash Collateral (or the appropriate portion thereof) provided to reduce any LC Issuer’s Fronting Exposure shall no longer be required to be held as Cash Collateral pursuant to this Section 2.20(m) following (A) the

elimination of such Fronting Exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (B) the determination by the Agent and each LC Issuer that there exists Cash Collateral in excess of the amount required to be maintained pursuant to the terms of this Agreement, in which case, such Cash Collateral (in the case of clause (A) above) or excess amounts (in the case of clause (B) above), as applicable, shall be returned to the Borrower upon its request therefor to the extent such Cash Collateral was provided by the Borrower; provided that, subject to Section 2.24, the Person providing Cash Collateral may agree that Cash Collateral in excess of such Fronting Exposure at any time shall be held to support future anticipated Fronting Exposure or other Obligations.

(n) Independence. The Borrower acknowledges that the rights and obligations of each LC Issuer under each Facility LC are independent of the existence, performance or nonperformance of any contract or arrangement underlying such Facility LC, including contracts or arrangements between such LC Issuer and the Borrower and between the Borrower and the beneficiary of such Facility LC.

(a) Request of Extension. No later than thirty (30) days prior to the Scheduled Revolving Credit Maturity Date, the Borrower shall have the option to request (such request, an “Extension Request”) an extension of the Scheduled Revolving Credit Maturity Date for an additional one-year period; provided that no more than two (2) of such one-year extensions shall be permitted hereunder. Any election by a Lender to extend its Commitment will be at such Lender’s sole discretion and such Lender’s failure to respond to an Extension Request within fifteen (15) Business Days from the date of delivery of such Extension Request shall be deemed to be a refusal by such Lender to so extend its Scheduled Revolving Credit Maturity Date.

(b) Extension; Conditions Precedent. Subject to the Agent’s receipt of written consents to such Extension Request from the Required Lenders (each such consenting Lender, an “Extending Lender”), the Scheduled Revolving Credit Maturity Date shall be extended for an additional one-year period for each Extending Lender; provided that (i) each non-consenting Lender (together with its successors and assigns, each a “Non-Extending Lender”) shall be required only to complete its Commitment up to the previously effective Scheduled Revolving Credit Maturity Date (without giving effect to such Extension Request), (ii) the Commitment of each Extending Lender (including the Commitment of each Additional Lender (as defined below)) shall be on the same terms and conditions as the Commitment of each other Extending Lender and Additional Lender, (iii) on the date of any extension of the Scheduled Revolving Credit Maturity Date under this Section 2.21, the conditions set forth in Section 4.3 shall be satisfied and (iv) the Borrower shall deliver to the Agent a certificate dated as of the date of any extension, signed by an Authorized Officer certifying that (A) the conditions set forth in Section 4.3 shall be satisfied and (B) attaching certified copies of resolutions of the board of directors or other equivalent governing body of the General Partner approving such extension.

(c) Payments to Non-Extending Lenders; Reduction of Commitment. All Obligations and other amounts payable hereunder to each Non-Extending Lender shall become due and payable by the Borrower on the previously effective Scheduled Revolving Credit Maturity Date (without giving effect to such Extension Request) or the earlier replacement of such Non-Extending Lender pursuant to Section 2.19. The Aggregate Commitment shall be reduced by the total Commitments of all Non-Extending Lenders expiring on such previously effective Scheduled Revolving Credit Maturity Date (without giving effect to such Extension Request) unless and until one or more lenders (including other Lenders) shall have agreed to assume a, or increase its, Commitment hereunder (in which case such portion of the Aggregate Commitment shall be reinstated pursuant to this Section). Each Non-Extending Lender shall be required to maintain its original Commitment up to the previously effective Scheduled Revolving Credit Maturity Date (without giving effect to such Extension Request) that such Non-Extending Lender had previously agreed upon.

(d) Replacement of Lender. The Borrower shall have the right at any time to replace each Non-Extending Lender (i) with one or more financial institutions (each, an “Additional Lender”) (A) that are existing Lenders (and, if any such Additional Lender is already a Lender, its Commitment shall be in addition to such Lender’s Commitment hereunder on such date) or (B) that are not existing Lenders; provided that any financial institution that is not an existing Lender (x) must be an Eligible Assignee and (y) must become a Lender for all purposes under this Agreement pursuant to an Assignment and Assumption Agreement and (ii) on a non-pro rata basis with any such financial institution that is willing to grant the Extension Request, including at a higher or lower Commitment than such Non-Extending Lenders’ respective Commitments; provided that any replacement of one or more Non-Extending Lenders that results in a higher Aggregate Commitment than the Aggregate Commitment in effect prior to such Extension Request shall, to the extent of such excess, be effected pursuant to the requirements of Section 2.22.

(a) Request of Commitment Increase. At any time and from time to time prior to the Scheduled Revolving Credit Maturity Date, the Borrower shall have the right to request and effectuate increases in the Aggregate Commitment (each a “Commitment Increase”) without the consent of any Lender (other than a Lender that is increasing its Commitment in connection with such request) by adding to this Agreement pursuant to a Commitment Increase Agreement one or more financial institutions as Lenders (collectively, the “New Lenders”) or by allowing one or more existing Lenders to increase their respective Commitments (each an “Increasing Lender”); provided that:

(ii) unless the Agent otherwise consents, each Commitment Increase shall be in a minimum principal amount of $10,000,000 and in integral multiples of $5,000,000 in excess thereof or, if less, the remaining amount permitted pursuant to clause (iii) below;

(iii) in no event shall the aggregate amount of all Commitment Increases result in the Aggregate Commitment exceeding 150% of the Aggregate Commitment in effect on the Closing Date;

(v) on the effective date of any Increase (the “Increase Date”), the applicable conditions set forth in Section 4.3 shall be satisfied (or waived in accordance with Section 9.1); and

(vi) such increased Commitments shall be on the same terms as the existing Commitments (subject to the Borrower’s ability to extend any Commitment pursuant to Section 2.21).

(b) Deliverables for Commitment Increase. Each Commitment Increase must be requested by written notice from the Borrower to the Agent, specifying (x) the proposed Increase Date and (y) the amount of the requested Commitment Increase. To effect a Commitment Increase, the Borrower, the Agent, one or more New Lenders and/or Increasing Lenders (and, to the extent the consent of the LC Issuers and the Swing Line Lender is necessary under the terms of this Agreement, the LC Issuers and the Swing Line Lender) shall execute a Commitment Increase Agreement, and such Commitment Increase shall be effective on the Increase Date specified therein; provided that, as a condition to the effectiveness of any Commitment Increase, if requested by the Agent, the Borrower shall deliver to the Agent:

(i) a certificate dated as of the Increase Date, signed by an Authorized Officer certifying that (A) each of the conditions to such increase set forth in this Section 2.22 shall have occurred and been complied with and (B) attached thereto is a certified copy of resolutions of the board of directors or other equivalent governing body of the General Partner approving such Commitment Increase; and

(ii) a favorable customary opinion of counsel for the Borrower (which may be in-house counsel), in form and substance reasonably acceptable to the Agent, covering such matters relating to the Commitment Increase as the Agent may reasonable request.

(c) Notification of Commitment Increase; Reallocation of Credit Exposure. On each Increase Date, upon fulfillment of the conditions set forth in paragraph (b) above and Section 4.3, (i) the Agent shall notify the Lenders (including each New Lender) and the Borrower of the occurrence of the Commitment Increase effected on such Increase Date and shall record in the Register the relevant information with respect to each Increasing Lender and each New Lender, (ii) the Aggregate Outstanding Credit Exposure will be reallocated among the Lenders in accordance with their revised Pro Rata Shares (and the Lenders agree to make all payments and adjustments necessary to effect the reallocation and the Borrower shall pay any and all costs required pursuant to Section 3.4 in connection with such reallocation as if such reallocation were a repayment) and (iii) each New Lender that executes a Commitment Increase Agreement shall be a Lender for all purposes under this Agreement.

(a) Amount of Swing Line Loans. Upon (x) the satisfaction of the conditions precedent set forth in Section 4.2 and (y) if such Swing Line Loan is to be made on the date of the initial Advance hereunder, the satisfaction of the conditions precedent set forth in Section

4.1, from and including the Closing Date and prior to the Revolving Credit Maturity Date, the Borrower may request and the Swing Line Lender shall, on the terms and conditions set forth in this Agreement, make Swing Line Loans to the Borrower from time to time in an aggregate principal amount not to exceed the Swing Line Limit (it being agreed that the Swing Line Lender shall be obligated to make Swing Line Loans even if the aggregate principal amount of Swing Line Loans outstanding and/or requested by the Borrower at any time, when added to the aggregate principal amount of Revolving Loans made by the Swing Line Lender in its capacity as a Lender at such time and its LC Obligations at such time, would exceed the Swing Line Lender’s own Commitment as a Lender at such time); provided that at no time shall (i) the Aggregate Outstanding Credit Exposure at any time exceed the Aggregate Commitment or (ii) the sum of (A) the Swing Line Lender’s Pro Rata Share of the Swing Line Loans, plus (B) the outstanding Revolving Loans made by the Swing Line Lender pursuant to Section 2.1, plus (C) an amount equal to the Swing Line Lender’s ratable obligation to purchase participations in the LC Obligations at such time, exceed the Swing Line Lender’s Commitment at such time. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow Swing Line Loans at any time prior to the Revolving Credit Maturity Date. Subject to the terms and conditions of this Agreement (including the submission of a Borrowing Notice in compliance with Section 2.8 and the satisfaction of the applicable conditions precedent set forth in Article IV), the Borrower may request an Advance (other than a Swing Line Loan) hereunder for the purpose of repaying any Swing Line Loan.

(b) Borrowing Notice. The Borrower shall deliver to the Agent and the Swing Line Lender irrevocable notice (a “Swing Line Borrowing Notice”) not later than 2:00 p.m. on the Borrowing Date of each Swing Line Loan, specifying (i) the applicable Borrowing Date (which date shall be a Business Day), and (ii) the aggregate amount of the requested Swing Line Loan which shall be an amount not less than $500,000 and in an integral multiple of $100,000 in excess thereof. The Swing Line Loans shall bear interest at the Swing Line Rate.

(c) Making of Swing Line Loans. Promptly after receipt of a Swing Line Borrowing Notice, the Agent shall notify each Lender by fax, or other similar form of transmission, of the requested Swing Line Loan. Not later than 4:00 p.m. on the applicable Borrowing Date, the Swing Line Lender shall make available the Swing Line Loan to the Borrower on the Borrowing Date at the Agent’s address specified pursuant to Section 9.20.

(i) Each Swing Line Loan shall be paid in full by the Borrower on or before the earlier of (A) the fourteenth (14th) Business Day after the Borrowing Date for such Swing Line Loan and (B) the Revolving Credit Maturity Date; provided, that such payment shall not be made by the proceeds of any other Swing Line Loans.

(ii) The Swing Line Lender may, by written notice given to the Agent not later than 10:00 a.m. on any Business Day, require the Lenders (including the Swing Line Lender) to acquire participations on such Business Day in all or a portion of the Swing Line Loans outstanding. Such notice shall specify the aggregate amount of Swing Line Loans in which Lenders will participate. Promptly upon receipt of such notice, the Agent will give notice thereof to each Lender, specifying in such notice such Lender’s

Pro Rata Share of such Swing Line Loan or Swing Line Loans. Each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Agent, for the account of the Swing Line Lender, such Lender’s Pro Rata Share of such Swing Line Loan or Swing Line Loans. Each Lender acknowledges and agrees that its obligation to acquire participations in Swing Line Loans pursuant to this paragraph is unconditional, continuing, irrevocable and absolute and shall not be affected by any circumstances, including (A) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against the Agent, the Swing Line Lender or any other Person, (B) the occurrence or continuance of a Default or Event of Default, (C) any adverse change in the condition (financial or otherwise) of the Borrower, or (D) any other circumstances, happening or event whatsoever. Each Lender shall comply with its obligation under this Section 2.23(d) by wire transfer of immediately available funds, in the same manner as provided in Section 2. 8 with respect to Revolving Loans made by such Lender (and Section 2.8 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Agent shall promptly pay to the Swing Line Lender the amounts so received from the Lenders. In the event that any Lender fails to make payment to the Agent of any amount due under this Section 2.23(d), the Agent shall be entitled to receive, retain and apply against such obligation the principal and interest otherwise payable to such Lender hereunder until the Agent receives such payment from such Lender or such obligation is otherwise fully satisfied. The Agent shall notify the Borrower of any participations in any Swing Line Loan acquired pursuant to this paragraph, and thereafter payments in respect of such Swing Line Loan shall be made to the Agent and not to the Swing Line Lender. Any amounts received by the Swing Line Lender from the Borrower (or other party on behalf of the Borrower) in respect of a Swing Line Loan after receipt by the Swing Line Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Agent. All of such amounts received by the Agent in payment of Swing Line Loans shall be promptly remitted by the Agent to the Lenders that shall have made their payments pursuant to this paragraph and to the Swing Line Lender, as their interests may appear; provided that any such payment so remitted shall be repaid to the Swing Line Lender or to the Agent, as applicable, if and to the extent such payment is required to be refunded to the Borrower for any reason. The purchase of participations in a Swing Line Loan pursuant to this paragraph shall not relieve the Borrower of any default in the payment thereof.

(iii) In addition, on the fourteenth (14^th) Business Day after the Borrowing Date of any Swing Line Loan, the Borrower shall be deemed to have automatically given notice to the Agent requesting that each Lender make a Revolving Loan in the amount of such Lender’s Pro Rata Share of such Swing Line Loan (including any interest accrued and unpaid thereon), for the purpose of repaying such Swing Line Loan, in which case each Lender hereby absolutely and unconditionally agrees to fund to the Agent, for the account of the Swing Line Lender, such Lender’s Revolving Loan deemed requested under this clause (iii) at the Agent’s address specified pursuant to Section 9.20, no later than 4:00 p.m. on the date such notice is received by the Lender from the Agent if such notice is received at or before 2:00 p.m. (and otherwise before 11:00 a.m. on the next Business Day). Revolving Loans made pursuant to this Section 2.23(d)(iii) shall initially be Base Rate Loans and thereafter may be continued as Base Rate Loans or converted into Eurodollar Loans in the manner provided in Section 2.9 and

subject to the other conditions and limitations set forth in this Article II. Unless a Lender shall have notified the Swing Line Lender, prior to its making any Swing Line Loan, that any applicable condition precedent set forth in Section 4.1 or 4.2 had not then been satisfied, such Lender’s obligation to make Revolving Loans pursuant to this Section 2.23(d)(iii) to repay Swing Line Loans shall be unconditional, continuing, irrevocable and absolute and shall not be affected by any circumstances, including (A) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against the Agent, the Swing Line Lender or any other Person, (B) the occurrence or continuance of a Default or Event of Default, (C) any adverse change in the condition (financial or otherwise) of the Borrower, or (D) any other circumstances, happening or event whatsoever.

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

(i) Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in Section 9.1(b).

(ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VIII or otherwise) or received by the Agent from a Defaulting Lender pursuant to Section 11.1 will not be paid or distributed to such Defaulting Lender, but will instead be retained by the Agent in a segregated account until (subject to Section 2.24(b)) the termination of the Commitments and payment in full of all obligations of the Borrower hereunder and shall be applied at such time or times as may be determined by the Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to any LC Issuer or the Swing Line Lender hereunder; third, to Cash Collateralize the LC Issuers’ Fronting Exposure with respect to such Defaulting Lender in accordance with Section 2.20(m); fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Agent; fifth, if so requested by the Borrower, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement and (y) Cash Collateralize the LC Issuers’ future Fronting Exposure with respect to such Defaulting Lender with respect to future Facility LCs issued under this Agreement, in accordance with Section 2.20(m); sixth, to the payment of any amounts owing to the Lenders, the LC Issuers or the Swing Line Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, any LC Issuer or the Swing Line Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Event of Default exists, to the payment of any amounts owing to

the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations to the Borrower under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or LC Obligations in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Facility LCs were issued at a time when the conditions set forth in Section 4.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and LC Obligations owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or LC Obligations owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in LC Obligations and Swing Line Loans are held by the Lenders pro rata in accordance with the Aggregate Commitments without giving effect to Section 2.24(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.24(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(A) Anything herein to the contrary notwithstanding, during such period as a Lender is a Defaulting Lender, such Defaulting Lender will not be entitled to any fees accruing during such period pursuant to Section 2.5 and Section 2.20(e) (without prejudice to the rights of the Non-Defaulting Lenders in respect of such fees) and the Borrower shall not be required to pay any fee that otherwise would not have been required to have been paid to that Defaulting Lender, provided, however that each Defaulting Lender shall be entitled to receive LC Participation Fees for any period during which that Lender is a Defaulting Lender to the extent (and only to the extent) allocable to its Pro Rata Share of the outstanding undrawn face amount of Facility LCs for which it has provided Cash Collateral pursuant to Section 2.20(m).

(B) With respect to any LC Participation Fees not required to be paid to any Defaulting Lender pursuant to clause (A) above, the Borrower shall (x) pay to each Non-Defaulting Lender that portion of any such LC Participation Fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in LC Obligations that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to each LC Issuer the amount of any such LC Participation Fee otherwise payable to such Defaulting Lender to the extent allocable to such LC Issuer’s unreallocated or non-Cash Collateralized Fronting Exposure to such Defaulting Lender, if any, and (z) not be required to pay the remaining amount of any such LC Participation Fee.

(iv) Reallocation of Participations to Reduce Fronting Exposure. All or any part of such Defaulting Lender’s Fronting Exposure shall be automatically reallocated (effective on the day such Lender becomes a Defaulting Lender) among the Non-Defaulting Lenders in accordance with their respective Pro Rata Shares (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that (x) the conditions set forth in Section 4.2 are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the Outstanding Credit Exposure of any Non-Defaulting Lender to exceed such Non-Defaulting Lender’s Commitment. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation.

(v) Cash Collateral, Repayment of Swing Line Loans. If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrower shall not later than two (2) Business Days after written demand by the Agent (at the direction of any LC Issuer and/or the Swing Line Lender, as the case may be), without prejudice to any right or remedy available to it hereunder or under law, first, prepay Swing Line Loans in an amount equal to the Swing Line Lender’s Fronting Exposure, and second, Cash Collateralize the LC Issuers’ Fronting Exposure in accordance with the procedures set forth in Section 2.20(m).

(b) Defaulting Lender Cure. If the Borrower, the Agent, the Swing Line Lender and each LC Issuer agree in writing that a Lender is no longer a Defaulting Lender, the Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), such Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders and take such other actions as the Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Facility LCs and Swing Line Loans to be held pro rata by the Lenders in accordance with the Aggregate Commitments (without giving effect to Section 2.24(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender (and the Pro Rata Shares of each Lender will automatically be adjusted on a prospective basis to reflect the foregoing); provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

(c) New Swing Line Loans/Facility LCs. So long as any Lender is a Defaulting Lender, (i) the Swing Line Lender shall not be required to fund any Swing Line Loans unless it is satisfied that it will have no Fronting Exposure with respect to such Defaulting Lender’s participation interest therein after giving effect to such Swing Line Loan and (ii) no LC Issuer shall be required to issue or Modify any Facility LC unless it is satisfied that it will have no Fronting Exposure with respect to such Defaulting Lender’s participation interest therein after

giving effect thereto, in each case, after giving effect to such issuance or Modification, and after giving effect to any Cash Collateral provided in respect of, or reallocation pursuant to Section 2.24(a)(iv) of, such LC Issuer’s or Swing Line Lender’s Fronting Exposure with respect to such Defaulting Lender.

(a) Funding by Lenders; Presumption by the Agent. Unless the Agent shall have received notice from a Lender prior to the proposed time of any borrowing that such Lender will not make available to the Agent such Lender’s share of such Advance, the Agent may assume that such Lender has made such share available on such date in accordance with the terms hereof and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable borrowing available to the Agent, then the applicable Lender and the Borrower severally agree to pay to the Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Agent, at (i) in the case of a payment to be made by such Lender, the greater of the daily average Federal Funds Effective Rate and a rate determined by the Agent in accordance with banking industry rules on interbank compensation and (ii) in the case of a payment to be made by the Borrower, the interest rate applicable to such Loans. If the Borrower and such Lender shall pay such interest to the Agent for the same or an overlapping period, the Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable Advance to the Agent, then the amount so paid shall constitute such Lender’s Loan included in such borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Agent.

(b) Nature of Obligations of Lenders Regarding Extensions of Credit. The obligations of the Lenders under this Agreement to make the Loans or participate in Facility LCs are several and are not joint or joint and several. The failure of any Lender to make available its Pro Rata Share of any Advance requested by the Borrower shall not relieve it or any other Lender of its obligation, if any, hereunder to make its Pro Rata Share of such Advance available on the Borrowing Date, but no Lender shall be responsible for the failure of any other Lender to make its Pro Rata Share of such Advance available on the Borrowing Date.

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender or any LC Issuer;

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

(iii) impose on any Lender, any LC Issuer or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or any Facility LC or participation therein;

and the result of any of the foregoing shall be to increase the cost to the Agent or such other Recipient of making, converting into, continuing or maintaining any Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Recipient of participating in, issuing or maintaining any Facility LC (or of maintaining its obligation to participate in or to issue any Facility LC), or to reduce the amount of any sum received or receivable by such Recipient hereunder (whether of principal, interest or any other amount) then, upon written request of such Recipient, the Borrower shall promptly pay to such Recipient such additional amount or amounts as will compensate such Recipient for such additional costs incurred or reduction suffered; provided that the Borrower shall not be required to pay any such amounts to any Recipient under and pursuant to this Section which are owing as a result of any Specified Change if and to the extent such Recipient is not at such time generally assessing such costs in a similar manner to other similarly situated borrowers with similar credit facilities.

(b) Capital Requirements. If any Lender or LC Issuer determines that any Change in Law affecting such Lender or LC Issuer or any Lending Installation of such Lender or such Lender’s or LC Issuer’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender’s or LC Issuer’s capital or on the capital of such Lender’s or LC Issuer’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Facility LCs or Swing Line Loans held by, such Lender, or the Facility LCs issued by any LC Issuer, to a level below that which such Lender or LC Issuer or such Lender’s or LC Issuer’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or LC Issuer’s policies and the policies of such Lender’s or LC Issuer’s holding company with respect to capital adequacy and liquidity), then from time to time the Borrower will pay to such Lender or LC Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or LC Issuer or such Lender’s or LC Issuer’s holding company for any such reduction suffered; provided that the Borrower shall not be required to pay any such amounts to any Lender under and pursuant to this Section which are owing as a result of any Specified Change if and to the extent such Lender is not at such time generally assessing such costs in a similar manner to other similarly situated borrowers with similar credit facilities.

(c) Delay in Requests. Failure or delay on the part of any Lender or LC Issuer to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or LC Issuer’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or LC Issuer pursuant to this Section for any increased costs incurred or reductions suffered more than ninety (90) days prior to the date that such Lender or LC Issuer, as the case may be, notifies the Borrower of the Change in Law giving rise to such

increased costs or reductions, and of such Lender’s or LC Issuer’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the ninety-day period referred to above shall be extended to include the period of retroactive effect thereof).

Section 3.2. Changed Circumstances Affecting Eurodollar Rate Availability. In connection with any request for a Eurodollar Advance or a Base Rate Advance or a conversion to or continuation thereof, if for any reason (a) the Agent shall determine (which determination shall be conclusive and binding absent manifest error) that Dollar deposits are not being offered to banks in the London interbank Eurodollar market for the applicable amount and Interest Period of such Advance, (b) the Agent shall determine (which determination shall be conclusive and binding absent manifest error) that reasonable and adequate means do not exist for ascertaining the Eurodollar Rate for such Advance or (c) the Required Lenders shall determine (which determination shall be conclusive and binding absent manifest error) that the Eurodollar Rate does not adequately and fairly reflect the cost to such Lenders of making or maintaining such Advance during such Interest Period, then the Agent shall promptly give notice thereof to the Borrower and the other Lenders. Thereafter, until the Agent notifies the Borrower and the other Lenders that such circumstances no longer exist, (i) the obligation of the Lenders to make Eurodollar Advances and the right of the Borrower to convert any Advance to or continue any Advance as a Eurodollar Advance shall be suspended, and the Borrower shall, at the Borrower’s option, either (A) repay in full (or cause to be repaid in full) the then outstanding principal amount of each such Eurodollar Advance together with accrued interest thereon (subject to Section 2.15), on the last day of the then current Interest Period applicable to such Eurodollar Advance; or (B) convert, without premium or penalty and without liability for any amounts payable pursuant to Section 3.4, the then outstanding principal amount of each such Eurodollar Advance to a Base Rate Advance as of the last day of such Interest Period; and (ii) the Alternate Base Rate shall be calculated without giving effect to clause (c) of such definition.

Section 3.3. Laws Affecting Eurodollar Rate Availability. If, after the date hereof, the introduction of, or any change in, any Applicable Law or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any of the Lenders (or any of their respective Lending Installations) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, shall make it unlawful or impossible for any of the Lenders (or any of their respective Lending Installations) to honor its obligations hereunder to make or maintain any Eurodollar Advance, such Lender shall promptly give notice thereof to the Agent and the Agent shall promptly give notice to the Borrower and the other Lenders. Thereafter, until the Agent notifies the Borrower and the other Lenders that such circumstances no longer exist, (i) the obligations of the Lenders to make Eurodollar Advances, and the right of the Borrower to convert any Advance or continue any Advance as a Eurodollar Advance shall be suspended and thereafter the Borrower may select only Base Rate Loans, (ii) if any of the Lenders may not lawfully continue to maintain a Eurodollar Advance to the end of the then current Interest Period applicable thereto, the applicable Loan shall immediately be converted to a Base Rate Loan for the remainder of such Interest Period and (iii) the Alternate Base Rate shall be calculated without giving effect to clause (c) of such definition.

Section 3.4. Funding Indemnification. If (i) any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, including pursuant to Section 9.19, (ii) a Eurodollar Advance is not made, continued or converted on the date specified by the Borrower in a Borrowing Notice or a Conversion/Continuation Notice for any reason other than default by the Lenders, (iii) a Eurodollar Advance is not prepaid on the date specified by the Borrower pursuant to Section 2.7 for any reason, or (iv) a Eurodollar Loan is assigned on a date which is not the last day of the applicable Interest Period as a result of a request by the Borrower pursuant to Section 2.19, then, except (a) as otherwise provided in this Agreement or (b) if arising in connection with a Lender becoming a Defaulting Lender or the replacement of such Lender pursuant to Section 2.19, for any such amounts that would be owing to such Lender, the Borrower will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance but excluding the Applicable Margin expected to be received by such Lender during the remainder of such Interest Period.

(a) LC Issuers. For purposes of this Section 3.5, the term “Lender” includes any LC Issuer.

(b) Payments Free of Taxes. Any and all payments to a Recipient by or on account of any obligation of the Borrower under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by Applicable Law. If any Applicable Law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with Applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding for Indemnified Tax been made.

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

(d) Indemnification by the Borrower. The Borrower shall indemnify each Recipient, within 30 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority; provided, however, the Borrower shall not be required to indemnify a Recipient pursuant to this Section 3.5(d) for any Indemnified Taxes unless such

Recipient makes written demand on the Borrower for indemnification for such Indemnified Taxes no later than one hundred twenty (120) days after the earlier of (i) the date on which the relevant Governmental Authority makes written demand upon such Recipient for payment of such Indemnified Taxes, and (ii) the date on which such Recipient has made payment of such Indemnified Taxes. A certificate satisfying the requirements of Section 3.6 as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Agent), or by the Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e) Indemnification by the Lenders. Each Lender shall severally indemnify the Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Agent for such Indemnified Taxes and without limiting the obligation of Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 12.2 relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Agent to the Lender from any other source against any amount due to the Agent under this Section 3.5(e).

(f) Evidence of Payments. As soon as practicable after any payment of Taxes by the Borrower to a Governmental Authority pursuant to this Section 3.5, the Borrower shall deliver to the Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Agent.

(i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Agent, at the time or times reasonably requested by the Borrower or the Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Agent as will enable the Borrower or the Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Sections 3.5(g)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in such applicable Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

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

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

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

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

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

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

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

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

(iii) To the extent the Agent is not acting as a Lender, the Agent shall comply with the requirements of this Section 3.5(g) to the same extent as if it were a Lender (whose obligations under this Section 3.5(g) shall be solely to the Borrower) since the date on which it became the Agent.

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

(h) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 3.5 (including by the payment of additional amounts pursuant to this Section 3.5), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this Section 3.5(h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 3.5(h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 3.5(h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(i) Survival. Each party’s obligations under this Section 3.5 shall survive the resignation or replacement of the Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

(j) Applicable Law. For purposes of this Section 3.5, the term “Applicable Law” includes FATCA.

Section 3.6. Lender Statements; Survival of Indemnity. Each Lender shall deliver a written statement of such Lender to the Borrower (with a copy to the Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth in reasonable detail the calculations upon which such Lender determined such amount and shall be final, conclusive and binding on the Borrower in the absence of manifest error. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the Eurodollar Rate applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement of any Lender shall (unless the subject of a good faith dispute by the Borrower) be payable within fifteen (15) days after demand and receipt by the Borrower of such written statement. The obligations of the Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive payment of the Obligations and termination of this Agreement.

Section 3.7. Alternative Lending Installation. If any Lender requests compensation under Section 3.1, or the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.5, or is unable to fund or maintain Eurodollar Advances or Eurodollar Loans, as applicable, as a result of the circumstances described in Section 3.3, then such Lender shall (at the request of the Borrower) use reasonable efforts to designate a different Lending Installation for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to

another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.1 or 3.5 or remedy the circumstances described in Section 3.3, as the case may be, in the future, and (ii) would not in the reasonable judgment of such Lender subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. A Lender shall not be required to make any such designation or assignment if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances requiring such designation or assignment cease to apply. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment, if and to the extent such Lender is at such time generally assessing such costs and expenses in a similar manner to other similarly situated borrowers with similar credit facilities.

Anything herein to the contrary notwithstanding, during such period as a Lender is a Defaulting Lender, to the fullest extent permitted by Applicable Law, such Lender will not be entitled to vote in respect of amendments and waivers hereunder and the Commitment and the outstanding Loans or other extensions of credit of such Lender hereunder will not be taken into account in determining whether the Required Lenders or all of the Lenders, as required, have approved any such amendment or waiver (and the definition of “Required Lenders” will automatically be deemed modified accordingly for the duration of such period); provided, that any such amendment or waiver that would increase or extend the term of the Commitment of such Defaulting Lender, extend the date fixed for the payment of principal or interest owing to such Defaulting Lender hereunder, reduce the principal amount of any obligation owing to such Defaulting Lender, reduce the amount of or the rate or amount of interest on any amount owing to such Defaulting Lender or of any fee payable to such Defaulting Lender hereunder, or alter the terms of this proviso, will require the consent of such Defaulting Lender.

Section 9.2. Survival of Representations. All representations and warranties of the Borrower contained in this Agreement shall survive the making of the Credit Extensions herein contemplated.

Section 9.3. Governmental Regulation. Anything contained in this Agreement to the contrary notwithstanding, no Lender or LC Issuer shall be obligated to extend credit to the Borrower in violation of any limitation or prohibition provided by any applicable statute or regulation.

Section 9.4. Headings. Section headings in the Loan Documents are for convenience of reference only, and shall not govern the interpretation of any of the provisions of the Loan Documents.

Section 9.5. Entire Agreement. The Loan Documents embody the entire agreement and understanding among the Borrower, the Agent and the Lenders and supersede all prior agreements and understandings among the Borrower, the Agent and the Lenders relating to the subject matter thereof.

Section 9.6. Several Obligations; Benefits of this Agreement. The respective obligations of the Lenders hereunder are several and not joint and no Lender shall be the partner or agent of any other (except to the extent to which the Agent is authorized to act as such). The failure of any Lender to perform any of its obligations hereunder shall not relieve any other Lender from any of its obligations hereunder. This Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and assigns; provided, that the parties hereto expressly agree that each Arranger shall enjoy the benefits of the provisions of Sections 9.7, 9.11 and 10.9 to the extent specifically set forth therein and shall have the right to enforce such provisions on its own behalf and in its own name to the same extent as if it were a party to this Agreement.

(a) Costs and Expenses. The Borrower shall reimburse the Agent and the Arrangers for all reasonable out-of-pocket costs and expenses (including the reasonable fees and expenses of Bracewell & Giuliani LLP, counsel to Citi in its capacity as Agent and an Arranger, and no other counsel of any other Lender or Arranger) paid or incurred by the Agent or the Arrangers in connection with the investigation, preparation, negotiation, documentation, execution, delivery, syndication, distribution (including via the internet), review, amendment, modification and administration of the Loan Documents. The Borrower also agrees to reimburse the Agent, the Syndication Agent, the Co-Documentation Agents, the Arrangers, the Lenders and the LC Issuers (each such Person being called a “Reimbursed Party” and collectively, the “Reimbursed Parties”) for all costs and out-of-pocket expenses (including, without limitation, the reasonable fees and disbursements of counsel, which shall be limited to a single firm of counsel for the Reimbursed Parties, taken as a whole, and, if reasonably necessary, a single firm of local or regulatory counsel in each appropriate jurisdiction and a single firm of special counsel for each relevant specialty, in each case for the Reimbursed Parties, taken as a whole and, solely in the case of an actual or perceived conflict of interest (as reasonably identified by a Reimbursed Party), where the Reimbursed Party affected by such conflict informs the Borrower of such conflict, one additional firm of counsel in each relevant jurisdiction for the affected Reimbursed Parties similarly situated, taken as a whole) paid or incurred by any Reimbursed Party in connection with the enforcement of any of their respective rights and remedies under the Loan Documents.

(b) Indemnification. The Borrower hereby further agrees to indemnify the Agent, the Syndication Agent, the Co-Documentation Agents, each Arranger, each Lender, each LC Issuer and each of their respective Related Parties (each such Person being called an “Indemnitee”) from and against all losses, claims, damages, penalties, judgments, liabilities and

expenses (including, without limitation, all expenses of litigation or preparation therefor whether or not such Indemnitee is a party thereto, and all reasonable fees and disbursements of counsel, which shall be limited to a single firm of counsel for all Indemnitees, taken as a whole, and, if reasonably necessary, a single firm of local or regulatory counsel in each appropriate jurisdiction and a single firm of special counsel for each relevant specialty, in each case for all Indemnitees, taken as a whole and, solely in the case of an actual or perceived conflict of interest (as reasonably identified by an Indemnitee) where the Indemnitee affected by such conflict informs the Borrower of such conflict, one additional firm of counsel in each relevant jurisdiction for the affected Indemnitees similarly situated, taken as a whole) which any of them may pay or incur arising out of or relating to this Agreement, the other Loan Documents, the transactions contemplated hereby or the direct or indirect application or proposed application of the proceeds of any Credit Extension hereunder except to the extent such losses, claims, damages, penalties, judgments, liabilities or expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from (1) the gross negligence, bad faith or willful misconduct of such Indemnitee, (2) a material breach by such Indemnitee of its obligations under this Agreement or (3) claims of one or more Indemnitees against another Indemnitee (other than claims against the Agent or the Arrangers in their capacities as such) and not involving any act or omission of the Borrower or any of its Related Parties. In the case of an investigation, litigation or other proceeding to which the indemnity in this Section 9.7(b) applies, such indemnity will be effective whether or not such investigation, litigation or proceeding is brought by the Borrower, any of its directors, security holders or creditors, an Indemnitee or any other person or an Indemnitee is otherwise a party thereto and whether or not the transactions contemplated by this Agreement are consummated. The obligations of the Borrower under this Section 9.7(b) shall survive the termination of this Agreement. In no event shall this clause (b) operate to expand the obligations of the Borrower under the first sentence of clause (a) above to require the Borrower to reimburse or indemnify the Lenders, the LC Issuers, the Syndication Agent or the Co-Documentation Agents for any amounts of the type described therein. This Section 9.7(b) shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim.

Section 9.8. Numbers of Documents. All statements, notices, closing documents, and requests hereunder shall be furnished to the Agent with sufficient counterparts so that the Agent may furnish one to each Lender and LC Issuer to the extent that the Agent deems necessary.

Section 9.9. Accounting. Except as provided to the contrary herein, all accounting terms used in the calculation of any financial covenant or test shall be interpreted and all accounting determinations hereunder in the calculation of any financial covenant or test shall be made in accordance with Agreement Accounting Principles.

Section 9.10. Severability of Provisions. Any provision in any Loan Document that is held to be inoperative, unenforceable, or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining provisions in that jurisdiction or the operation, enforceability, or validity of that provision in any other jurisdiction, and to this end the provisions of all Loan Documents are declared to be severable.

Section 9.11. Nonliability; Waiver of Consequential Damages. The relationship between the Borrower on the one hand and the Lenders and the Agent on the other hand shall be solely that of borrower and lender. None of the Agent, the Arrangers, the LC Issuers nor the Lenders shall have any fiduciary responsibilities to the Borrower. None of the Agent, the Arrangers, the LC Issuers nor the Lenders undertakes any responsibility to the Borrower to review or inform the Borrower of any matter in connection with any phase of the Borrower’s business or operations. The Borrower agrees that none of the Agent, the Arrangers, the LC Issuers nor the Lenders shall have liability (whether direct or indirect, in contract, tort or otherwise) to the Borrower or any of its Affiliates or any of their respective security holders or creditors for losses suffered in connection with, arising out of, or in any way related to, the transactions contemplated and the relationship established by the Loan Documents, or any act, omission or event occurring in connection therewith, except to the extent such liability is determined in a final non-appealable judgment by a court of competent jurisdiction to have resulted from (i) the gross negligence, bad faith or willful misconduct of the party from which recovery is sought or (ii) a material breach by the party from which recovery is sought of its obligations under this Agreement. Each party hereto agrees that no other party hereto nor any of its Related Parties shall have any liability to any other party hereto (or its Related Parties) on any theory of liability for any special, indirect, consequential or punitive damages (including without limitation, any loss of profits, business or anticipated savings) in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby; provided that this waiver shall in no way limit the Borrower’s indemnification obligations in Section 9.7(b) to the extent of any third-party claim for any of the foregoing, including the Borrower’s obligation to indemnify Indemnitees for special, indirect, consequential or punitive damages awarded against an Indemnitee.

Section 9.12. Confidentiality. Each of the Agent, the LC Issuers and the Lenders agrees that any Information (as defined below) delivered or made available to it shall (i) be kept confidential, (ii) be used solely in connection with evaluating, approving, structuring, administering or enforcing the credit facility contemplated hereby and (iii) not be provided to any other Person; provided that nothing in clauses (i) and (iii) above shall prevent the Agent, any LC Issuer or any Lender from disclosing such information (a) to its Related Parties (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by, or required to be disclosed to, any rating agency, or regulatory or similar authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) in response to any order of any court or other governmental authority having jurisdiction over it or as may otherwise be required pursuant to any requirement of law or as requested by any self-regulatory body (in which case it shall (i) promptly notify the Borrower in advance of disclosure, to the extent permitted by law and to the extent practicable, and (ii) so furnish only that portion of such Information which it is legally required to disclose), (d) if legally compelled to do so in connection with any litigation or similar proceeding (in which case it shall (i) promptly notify the Borrower in advance of disclosure, to the extent permitted by law and to the extent practicable, and (ii) so furnish only that portion of such Information which it is legally required to disclose), (e) to any other party hereto, (f) in connection with the exercise of any remedies under this Agreement or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (g) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its

rights or obligations under this Agreement, or (ii) any actual or prospective party (or its managers, administrators, trustees, partners, directors, officers, employees, agents, advisors and other representatives) to any swap, derivative or other transaction under which payments are to be made by reference to the Borrower and its obligations, this Agreement or payments hereunder, (h) with the consent of the Borrower, (i) to Gold Sheets and other similar bank trade publications, such information to consist of deal terms and other information customarily found in such publications, or (j) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Agent, any LC Issuer or any Lender or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower or its Related Parties and which is not known to be subject to a duty of confidentiality to the Borrower or its Affiliates (unless and until such Person is made aware of the confidential nature of such information, if any) or (k) to governmental regulatory authorities in connection with any regulatory examination of the Agent, any LC Issuer or any Lender or in accordance with the Agent’s, any LC Issuer’s or any Lender’s regulatory compliance policy if the Agent or such LC Issuer or Lender deems necessary for the mitigation of claims by those authorities against the Agent, such LC Issuer or such Lender or any of its subsidiaries or affiliates. For purposes of this Section, “Information” means all information received from the Borrower or any of its Related Parties relating to the Borrower or any Affiliate thereof or any of their respective businesses, assets, properties, operations, products, results or condition (financial or otherwise) other than (i) any such information that is received by the Agent, any LC Issuer or any Lender from a source other than the Borrower and which is not known to be subject to a duty of confidentiality to the Borrower or its Affiliates (unless and until such Person is made aware of the confidential nature of such information, if any), (ii) information that is publicly available other than as a result of the breach of a duty of confidentiality by such Person or its Related Parties or by another Person known by any of the foregoing to be subject to such a duty of confidentiality, (iii) information already known to or, other than information described in clause (i) above, in the possession of the Agent, any LC Issuer or any Lender prior to its disclosure by the Borrower, or (iv) information that is independently developed, discovered or arrived at by the Agent, any LC Issuer or any Lender. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Section 9.13. Lenders Not Utilizing Plan Assets. Each Lender represents and warrants that none of the consideration used by such Lender to make its Loans constitutes for any purpose of ERISA or Section 4975 of the Code assets of any “plan” as defined in Section 3(3) of ERISA or Section 4975 of the Code and the rights and interests of such Lender in and under the Loan Documents shall not constitute such “plan assets” under ERISA.

Section 9.14. Nonreliance. Each Lender hereby represents that it is not relying on or looking to any margin stock (as defined in Regulation U) for the repayment of the Credit Extensions provided for herein.

Section 9.15. Disclosure. The Borrower and each Lender, including the LC Issuers, hereby acknowledge and agree that Citibank and/or its Affiliates from time to time may hold investments in, make other loans to or have other relationships with the Borrower and its Affiliates.

Section 9.16. USA Patriot Act. The Agent and each Lender hereby notifies the Borrower that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act.

Section 9.17. Excluded Subsidiaries. The Borrower shall have the right, at any time with prior written notice to the Agent, to (i) designate any Subsidiary as an Excluded Subsidiary in accordance with the requirements of such definition or (ii) remove any Subsidiary from being an Excluded Subsidiary; provided that with respect to any Subsidiary, after the second designation of such Subsidiary as a Non-Excluded Subsidiary from an Excluded Subsidiary, such Subsidiary may not be re-designated as an Excluded Subsidiary at a later date.

Section 9.18. Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one agreement, and any of the parties hereto may execute this Agreement by signing any such counterpart. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic method of transmission shall be effective as delivery of a manually executed original counterpart of this Agreement.

Section 9.19. Removal of Lender. Notwithstanding anything herein or in any other Loan Document to the contrary, the Borrower may, at any time in its sole discretion, remove any Lender upon 15 Business Days’ written notice to such Lender and the Agent (the contents of which notice shall be promptly communicated by the Agent to the LC Issuers and the Lenders), such removal to be effective at the expiration of such 15-day notice period; provided, however, that no Lender may be removed hereunder at a time when an Event of Default shall have occurred and be continuing; and provided, further, that if such Lender is an LC Issuer that has issued any outstanding Facility LCs at such time, its rights and obligations as an LC Issuer with respect to such Facility LCs shall continue in full force and effect, notwithstanding its removal as a Lender. Each notice by the Borrower under this Section 9.19 shall constitute a representation by the Borrower that the removal described in such notice is permitted under this Section 9.19. Concurrently with such removal and as a condition thereof, the Borrower shall pay to such removed Lender (or, if such Lender is a Defaulting Lender, to Agent) all amounts owing to such Lender hereunder (including any amounts arising under Section 3.4 as a consequence of such removal) and under any other Loan Document in immediately available funds. Upon full and final payment hereunder of all amounts owing to such removed Lender, such Lender shall make appropriate entries in its accounts evidencing payment of all Loans hereunder and releasing the Borrower from all obligations owing to the removed Lender in respect of the Loans hereunder and surrender to the Agent for return to the Borrower any Notes of the Borrower then held by it. Effective immediately upon such full and final payment, such removed Lender will not be considered to be a “Lender” for purposes of this Agreement, except for the purposes of any provision hereof that by its terms survives the termination of this Agreement and the payment of the amounts payable hereunder. Effective immediately upon such removal, the Commitment of such removed Lender shall immediately terminate. Such removal will not, however, affect the Commitments of any other Lenders hereunder.

(a) Notices. Except as otherwise permitted by Section 2.14, all notices, requests and other communications to any party hereunder shall be in writing (including electronic transmission, facsimile transmission or similar writing) and shall be given to such party: (x) in the case of the Borrower, the Lenders, the LC Issuers or the Agent, at its address or facsimile number set forth on the signature pages hereof or, (y) in the case of any party, at such other address or facsimile number as such party may hereafter specify for the purpose by notice to the Agent and the Borrower in accordance with the provisions of this Section 9.20. Each such notice, request or other communication shall be effective (i) if given by facsimile transmission, when transmitted to the facsimile number specified in this Section and confirmation of receipt is received, (ii) if given by mail, three (3) Business Days after such communication is deposited in the mail with first class postage prepaid, addressed as aforesaid, or (iii) if given by any other means, when delivered (or, in the case of electronic transmission, received) at the address specified in this Section; provided that, subject to Section 2.14, notices to the Agent under Article II shall not be effective until received.

(b) Electronic Communications. Notices and other communications to the Lenders and the LC Issuers hereunder may be delivered or furnished by electronic communication (including e-mail and Internet or intranet websites) pursuant to procedures approved by the Agent, provided that the foregoing shall not apply to notices to any Lender or LC Issuer pursuant to Section 2.16 if such Lender or LC Issuer, as applicable, has notified the Agent that it is incapable of receiving notices under such Section by electronic communication. The Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications.

(c) Change of Address. The Borrower, the Agent, any LC Issuer and any Lender may each change the address for service of notice upon it by a notice in writing to the other parties hereto.

Section 10.1. Appointment and Authority. Each of the Lenders and the LC Issuers hereby irrevocably designates and appoints Citibank to act on its behalf as the Agent hereunder and under the other Loan Documents and authorizes the Agent to take such actions on its behalf and to exercise such powers as are delegated to the Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Agent, the LC Issuers and the Lenders, and neither the Borrower nor any Subsidiary thereof shall have rights as a third party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other

Loan Documents (or any other similar term) with reference to the Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

Section 10.2. Rights as a Lender. The Person serving as the Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for, and generally engage in any kind of business with, the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Agent hereunder and without any duty to account therefor to the Lenders.

Section 10.3. Exculpatory Provisions. The Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Agent:

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether an Event of Default has occurred and is continuing;

(b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents); provided that the Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Agent to liability or that is contrary to any Loan Document or Applicable Law, including for the avoidance of doubt, any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and

(c) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Agent or any of its Affiliates in any capacity.

The Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 9.1) or (ii) in the absence of its own gross negligence, bad faith or willful misconduct as determined by a court of competent jurisdiction by a final and nonappealable judgment. The Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until notice describing such Default or Event of Default is given to the Agent in writing by the Borrower, a Lender or an LC Issuer.

The Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Agent.

Section 10.4. Reliance by the Agent. The Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) reasonably believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Agent also may rely upon any statement made to it orally or by telephone and reasonably believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance or Modification of a Facility LC, that by its terms must be fulfilled to the satisfaction of a Lender or an LC Issuer, the Agent may presume that such condition is satisfactory to such Lender or LC Issuer unless the Agent shall have received notice to the contrary from such Lender or LC Issuer prior to the making of such Loan or the issuance or Modification of such Facility LC. The Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 10.5. Delegation of Duties. The Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents selected and appointed by the Agent. The Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Agent and any such sub agent, and shall apply to their respective activities in connection with the syndication of the credit facility evidenced hereby as well as activities as Agent. The Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Agent acted with gross negligence, bad faith or willful misconduct in the selection of such sub-agents.

(a) The Agent may at any time give notice of its resignation to the Lenders, the LC Issuers and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower (and so long as no Event of Default shall have occurred and be continuing, subject to the approval of the Borrower, such approval not to be unreasonably withheld or delayed (it being understood and agreed that if such proposed successor Agent is unwilling or unable to be appointed as the successor Swing Line Lender or LC Issuer, as applicable, it shall not be unreasonable for the Borrower to withhold its

consent)), to appoint a successor from among the Lenders, which shall be a bank with an office in the United States having capital and retained earnings of at least $100,000,000, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Agent may (but shall not be obligated to), on behalf of the Lenders and the LC Issuers, appoint a successor Agent meeting the qualifications set forth above; provided that if the Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then all payments, communications and determinations provided to be made by, to or through the Agent shall instead be made by or to each Lender directly, until such time as the Required Lenders appoint a successor Agent as provided for above in this paragraph (with the approval of the Borrower to the extent required above). Whether or not a successor has been appointed, such resignation of the retiring Agent shall become effective in accordance with such notice on the Resignation Effective Date (except that in the case of any collateral security held by the retiring Agent on behalf of the Lenders, the Swing Line Lender or any LC Issuer under any of the Loan Documents, the retiring Agent shall continue to hold such collateral security until such time as a successor Agent is appointed and accepts such appointment).

(b) With effect from the Resignation Effective Date (1) the retiring Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents and (2) except for any indemnity payments owed to the retiring Agent, all payments, communications and determinations provided to be made by, to or through the Agent shall instead be made by or to each Lender and LC Issuer directly, until such time, if any, as the Required Lenders appoint a successor Agent as provided for above. Upon the acceptance of a successor’s appointment as Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring or retired Agent (other than any rights to indemnity payments owed to the retiring Agent), and the retiring Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents. The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article X and Section 9.7 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Agent was acting as Agent. In the event that there is a successor to the Agent by merger, or the Agent assigns its duties and obligations to an Affiliate pursuant to this Section 10.6, then the term “Prime Rate” as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent.

(c) Any resignation by Citibank as Agent pursuant to this Section shall, unless otherwise agreed, also constitute its resignation (as of the Resignation Effective Date) as an LC Issuer and Swing Line Lender (but, in the case of the LC Issuer, only with respect to any Facility LCs issued after such date of resignation). Upon the acceptance of a successor’s appointment as Agent hereunder (i) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring LC Issuer and Swing Line Lender, (ii) the retiring LC Issuer and Swing Line Lender shall be discharged from all of its duties and obligations in such capacities hereunder or under the other Loan Documents, and (iii) after such acceptance, the successor LC Issuer shall use commercially reasonable efforts to issue letters of credit in substitution for the Facility LCs issued by the retiring LC Issuer, if any, outstanding at the time of such succession.

Section 10.7. Non-Reliance on Agent and Other Lenders. Each Lender and LC Issuer acknowledges that it has, independently and without reliance upon the Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and LC Issuer also acknowledges that it will, independently and without reliance upon the Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Section 10.8. No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the Syndication Agent, the Co-Documentation Agents, or the Arrangers listed on the cover page or signature pages hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Agent, a Lender or an LC Issuer hereunder.

Section 10.9. Agent, Arrangers and Co-Documentation Agent Fees. The Borrower agrees to pay to the Agent, each Arranger and each Co-Documentation Agent, for their respective accounts, the fees agreed to by the Borrower pursuant to the applicable Fee Letters.

(a) The Lenders agree to reimburse and indemnify the Agent, the Syndication Agent, the Arrangers and the Co-Documentation Agents ratably in proportion to the Lenders’ Pro Rata Shares of the Aggregate Commitment (or, if the Aggregate Commitment has been terminated, of the Outstanding Credit Exposure) for any amounts not reimbursed by the Borrower (a) for which the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent is entitled to reimbursement by the Borrower under the Loan Documents, (b) for any other expenses incurred by the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent on behalf of the Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents and (b) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including for any such amounts incurred by or asserted against the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent in connection with any dispute between the Agent, the Syndication Agent, any Arranger any Co-Documentation Agent and any Lender or between two or more of the Lenders), or the enforcement of any of the terms of the Loan Documents or of any such other documents (collectively, the “Indemnified Costs”); provided that (i) no Lender shall be liable for any portion of the Indemnified Costs that are found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence, bad

faith or willful misconduct of the party seeking indemnification and (ii) any indemnification required pursuant to Section 3.4 shall, notwithstanding the provisions of this Section 10.9, be paid by the relevant Lender in accordance with the provisions thereof. The failure of any Lender to reimburse the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent, as the case may be, promptly upon demand for its Pro Rata Share of any amount required to be paid by the Lenders as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse the Agent, the Syndication Agent, any Arranger or any Co-Documentation Agent, as the case may be, for its Pro Rata Share of such amount, but no Lender shall be responsible for the failure of any other Lender to reimburse such Agent, Syndication Agent, Arranger or Co-Documentation Agent, as the case may be, for such other Lender’s Pro Rata Share of such amount. The obligations of the Lenders under this Section 10.9 shall survive payment of the Obligations and termination of this Agreement.

(b) Each Lender shall, ratably in accordance with its Pro Rata Share, indemnify the LC Issuers, and their respective Related Parties (to the extent not reimbursed by the Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except as result from such indemnitees’ gross negligence, bad faith or willful misconduct, as determined by a court of competent jurisdiction by final non-appealable judgment) that any such indemnitees may suffer or incur in connection with the Loan Documents or any action taken or omitted by such indemnitee under the Loan Documents.

Section 10.11. Agent May File Proofs of Claim. In case of the pendency of any proceeding under any Debtor Relief Law, the Lenders hereby agree that the Agent (irrespective of whether the principal of any Loan or LC Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Agent shall have made any demand on the Borrower) shall be entitled and empowered (but not obligated) by intervention in such proceeding or otherwise for and on behalf of the Lenders:

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, LC Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the LC Issuers and the Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the LC Issuers and the Agent and their respective agents and counsel and all other amounts due the Lenders and the Agent under Sections 2.5, 2.20(d), 9.7 and 10.9) allowed in such judicial proceeding; and

(b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender and LC Issuer to make such payments to the Agent and, in the event that the Agent shall consent to the making of such payments directly to the Lenders and the LC Issuers, to pay to the Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Agent and its agents and counsel, and any other amounts due the Agent under Sections 2.5, 2.20(d), 9.7 and 10.9.

Section 10.12. Trust Indenture Act. In the event that Citibank or any of its Affiliates shall be or become an indenture trustee under the Trust Indenture Act of 1939 (as amended, the “Trust Indenture Act”) in respect of any securities issued or guaranteed by the Borrower or any of its Subsidiaries, the parties hereto acknowledge and agree that any payment or property received in satisfaction of or in respect of any Obligation of the Borrower or any of its Subsidiaries hereunder or under any other Loan Document by or on behalf of Citibank in its capacity as the Agent for the benefit of any Lender under any Loan Document (other than Citibank or an Affiliate of Citibank) and which is applied in accordance with the Loan Documents shall be deemed to be exempt from the requirements of Section 311 of the Trust Indenture Act pursuant to Section 311(b)(3) of the Trust Indenture Act.

Section 11.1. Setoff. In addition to, and without limitation of, any rights of the Lenders under Applicable Law, from and after the date that the Obligations have been accelerated pursuant to Section 8.2(a) or Section 8.2(b) (and for so long as such acceleration has not been rescinded by the Required Lenders), each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by Applicable Law, to set-off and apply any and all deposits (including all account balances, whether general or special, time or demand, provisional or final and whether or not collected or available) at any time held, and any other Indebtedness or obligations (in whatever currency) at any time held or owing, by such Lender or any such Affiliate, to or for the credit or account of the Borrower against any and all of the Obligations of the Borrower now or hereafter existing under this Agreement or any other Loan Document to such Lender or its Affiliates, irrespective of whether or not such Lender or Affiliate shall have made any demand under this Agreement or any other Loan Document and although such Obligations of the Borrower may be contingent or unmatured or are owed to a branch, office or Affiliate of such Lender different from the branch, office or Affiliate holding such deposit or obligated on such indebtedness; provided that in the event that any Defaulting Lender exercises any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Agent for further application in accordance with the provisions of Section 2.24 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Agent, the LC Issuers, and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each Lender and its Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender or its Affiliates may have. Each Lender and LC Issuer agrees to notify the Borrower and the Agent promptly after any such setoff and application; provided that the failure to give such notice shall not affect the validity of such setoff and application.

Section 11.2. Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Outstanding Credit Exposure (other than (i) payments received pursuant to Section 3.1, 3.2, 3.4 or 3.5, (ii) payments in accordance with Section 2.21 to any Lender which has not extended its Commitment pursuant to such Section and (iii) payments to which the LC Issuers or the Swing Line Lender are entitled under Section 2.20(g) or 2.23(d), as

applicable) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a portion of the Aggregate Outstanding Credit Exposure held by the other Lenders so that after such purchase each Lender will hold its Pro Rata Share of the Aggregate Outstanding Credit Exposure. If any Lender, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their respective Pro Rata Shares of the Aggregate Outstanding Credit Exposure. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

Section 12.1. Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Borrower, the Agent and the Lenders and their respective successors and assigns permitted hereby, except that (a) the Borrower shall not have the right to assign its rights or obligations under the Loan Documents without the prior written consent of each Lender, (b) any assignment by any Lender must be made in compliance with Section 12.3, and (c) any transfer by participation must be made in compliance with Section 12.2. Any attempted assignment or transfer by any party not made in compliance with this Section 12.1 shall be null and void, unless such attempted assignment or transfer is treated as a participation in accordance with Section 12.3(c). The parties to this Agreement acknowledge that clause (b) of this Section 12.1 relates only to absolute assignments and this Section 12.1 does not prohibit assignments creating security interests, including any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank or any central bank having jurisdiction over such Lender; provided that no such pledge or assignment creating a security interest shall release the transferor Lender from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 12.3. The Agent may treat each Lender which made any Credit Extension or which holds any Note as the owner thereof for all purposes hereof unless and until such Lender complies with Section 12.3; provided that the Agent may in its discretion (but shall not be required to) follow instructions from the Lender which made any Credit Extension or which holds any Note to direct payments relating to such Credit Extension or Note to another Person. Any assignee of the rights to any Credit Extension or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Lender, who at the time of making such request or giving such authority or consent is the owner of the rights to any Credit Extension (whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any subsequent holder or assignee of the rights to such Credit Extension.

(a) Permitted Participants; Effect. Any Lender may at any time, without the consent of, or notice to, the Borrower, any LC Issuer, the Swing Line Lender or the Agent, sell participations to any Person (other than a natural Person, the Borrower or any of the Borrower’s

Affiliates or Subsidiaries or, unless an Event of Default has occurred and is continuing, (x) any competitor of the Borrower or any of its Subsidiaries or (y) any other company engaged in the business of selling or distributing energy products; provided that this clause (y) shall not apply to any financial institution solely as a result of such Person trading in commodity products) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement and the other Loan Documents, if any, shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the owner of its Outstanding Credit Exposure and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents and all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interest and (iv) the Borrower, the Agent, the LC Issuers and Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 10.10 with respect to any payments made by such Lender to its Participant(s).

(b) Voting Rights. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of this Agreement other than any amendment, modification or waiver with respect to any Credit Extension or Commitment in which such Participant has an interest which would require consent of all of the Lenders or all of the affected Lenders pursuant to the terms of Section 9.1.

(c) Benefit of Certain Provisions. The Borrower further agrees that each Participant shall be entitled to the benefits of Sections 3.1, 3.2, 3.4 and 3.5 (subject to the requirements and limitations therein, including the requirements under Section 3.5(g) (it being understood that the documentation required under Section 3.5(g) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.3; provided that such Participant (i) agrees to be subject to the provisions of Sections 2.19 and 3.7 as if it were an assignee under Section 12.3; and (ii) shall not be entitled to receive any greater payment under Section 3.1 or 3.5, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower’s request and expense, to use commercially reasonable efforts to require such Participant comply with the provisions of Sections 2.19 and 3.7 as if it were a Lender and to cooperate with the Borrower in enforcing such provisions against such Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.1 as though it were a Lender; provided that such Participant agrees to be subject to Section 11.2 as though it were a Lender.

(d) Participant Register. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the

“Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Agent (in its capacity as Agent) shall have no responsibility for maintaining a Participant Register.

(a) Permitted Assignments. Any Lender (excluding for purposes of this Section 12.3(a), the Swing Line Lender or the LC Issuers) may at any time assign to one or more Eligible Assignees (such an assignee, a “Purchaser”) all or any part of its rights and obligations under the Loan Documents. The parties to each assignment shall execute and deliver to the Agent an Assignment and Assumption Agreement. Each such assignment with respect to an Eligible Assignee which is not a Lender or an Affiliate of a Lender or an Approved Fund shall either be in an amount equal to the entire applicable Commitment and Outstanding Credit Exposure of the assigning Lender or (unless each of the Borrower and the Agent otherwise consents) be in an aggregate amount not less than $5,000,000. The amount of the assignment shall be based on the Commitment or Outstanding Credit Exposure (if the Commitment has been terminated) subject to the assignment, determined as of the date of such assignment or as of the “Trade Date,” if the “Trade Date” is specified in the assignment. Each partial assignment made by a Lender shall be made as an assignment of a proportionate part of all of such Lender’s rights and obligations under this Agreement with respect to the Loans and Commitments assigned.

(b) Consents. The consent of the Agent, the Swing Line Lender and the LC Issuers (each such consent not to be unreasonably withheld or delayed) shall be required prior to an assignment becoming effective; provided that the consent of the Agent shall not be required for any assignment to a Person that is a Lender, an Affiliate of such Lender or an Approved Fund with respect to such Lender. The consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required prior to an assignment becoming effective unless (i) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund or (ii) an Event of Default has occurred and is continuing; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Agent within fifteen (15) days after having received notice thereof. Any consent required under this Section 12.3(b) shall not be unreasonably withheld or delayed.

(c) Effect; Effective Date. Subject to acceptance and recording of the assignment by the Agent pursuant to Section 12.3(d), upon (i) delivery to the Agent of an Assignment and Assumption Agreement pursuant to Section 12.3(a), together with any consents required by Section 12.3(b), (ii) payment by the parties to the Assignment and Assumption Agreement (other than the Borrower) of a $3,500 fee to the Agent for processing such assignment (unless such fee is waived by the Agent) and (iii) delivery to the Borrower and the

Agent of the documents required by Section 3.5, such Assignment and Assumption Agreement shall become effective on the effective date specified in such Assignment and Assumption Agreement. The Assignment and Assumption Agreement shall contain a representation and warranty by the Purchaser to the effect that none of the funds, money, assets or other consideration used to make the purchase and assumption of the Commitment and Outstanding Credit Exposure under the applicable assignment agreement constitutes “plan assets” as defined under ERISA and that the rights, benefits and interests of the Purchaser in and under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to this Agreement and any other Loan Document executed by or on behalf of the Lenders and shall have all the rights, benefits and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party thereto, and the transferor Lender shall be released with respect to the Commitment and Outstanding Credit Exposure assigned to such Purchaser without any further consent or action by the Borrower, the Lenders or the Agent. In the case of an assignment covering all of the assigning Lender’s rights, benefits and obligations under this Agreement, such Lender shall cease to be a Lender hereunder but shall continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Documents which survive payment of the Obligations and termination of the Loan Documents with respect to facts and circumstances occurring prior to the effective date of such assignment; provided that no assignment by a Defaulting Lender will constitute or effect a waiver or release of any claim of any party arising from such Lender being a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.3 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 12.2. Upon the consummation of any assignment to a Purchaser pursuant to this Section 12.3(c), the transferor Lender, the Agent and the Borrower shall, if the transferor Lender or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so that, upon cancellation and surrender to the Borrower of the Notes (if any) held by the transferor Lender, new Notes or, as appropriate, replacement Notes are issued to such transferor Lender, if applicable, and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments (or if the Aggregate Commitment has been terminated, their respective Outstanding Credit Exposure), as adjusted pursuant to such assignment.

(d) Register. The Agent, acting solely for this purpose as a non-fiduciary agent of the Borrower (and the Borrower hereby designates the Agent to act in such capacity), shall maintain at one of its offices in the United States a copy of each Assignment and Assumption Agreement delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated interest) of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(e) No Assignment to Certain Persons. No such assignment shall be made to (i) the Borrower or any of the Borrower’s Affiliates or Subsidiaries, (ii) any Defaulting Lender or

any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (ii) or (iii) unless an Event of Default has occurred and is continuing, (x) any competitor of the Borrower or any of its Subsidiaries or (y) any other company engaged in the business of selling or distributing energy products; provided that this clause (y) shall not apply to any financial institution solely as a result of such Person trading in commodity products.

(f) No Assignment to Natural Persons. No such assignment shall be made to a natural Person.

(g) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment make such additional payments to the Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Agent, the applicable Pro Rata Share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Agent, each LC Issuer, the Swing Line Lender and each other Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Facility LCs and Swing Line Loans in accordance with its Pro Rata Share. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder becomes effective under Applicable Law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Section 12.4. Dissemination of Information. The Borrower authorizes each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee”) and any prospective Transferee any and all information in such Lender’s possession concerning the creditworthiness of the Borrower and its Subsidiaries; provided that each Transferee and prospective Transferee agrees to be bound by Section 9.12.

Section 12.5. Tax Certifications. If any interest in any Loan Document is transferred to any Transferee which is not incorporated under the laws of the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 3.5.

Section 12.6. No Liability of General Partner. It is hereby understood and agreed that the General Partner shall have no personal liability, as general partner or otherwise, for the payment of any amount owing or to be owing hereunder or under the other Loan Documents. The Agent and the Lenders agree for themselves and their respective successors and assigns that no claim arising against the Borrower under any Loan Document with respect to the Obligations shall be asserted against the General Partner (in its individual capacity).

Section 13.1. CHOICE OF LAW. UNLESS OTHERWISE EXPRESSLY SET FORTH THEREIN, THE LOAN DOCUMENTS SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

Section 13.2. CONSENT TO JURISDICTION. THE BORROWER, THE AGENT AND EACH LENDER HEREBY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY AND OF THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER, THE AGENT AND EACH LENDER HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE BORROWER IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY THE BORROWER AGAINST THE AGENT OR ANY LENDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN NEW YORK, NEW YORK.

Section 13.3. WAIVER OF JURY TRIAL. THE BORROWER, THE AGENT AND EACH LENDER HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER.

IN WITNESS WHEREOF, the Borrower, the Lenders and the Agent have executed this Agreement as of the date first above written.

“Designated Rating” means, with respect to S&P, Moody’s and Fitch (collectively, the “Rating Agencies” and each a “Rating Agency”), (i) the rating assigned by such Rating Agency to the Loans at any time such a rating is in effect, (ii) if and only if such Rating Agency does not have in effect a rating described in the preceding clause (i), the rating assigned by such Rating Agency to the 2013 Term Loan Facility at any time such a rating is in effect, (iii) if and only if such Rating Agency does not have in effect a rating described in the preceding clauses (i) or (ii), the Borrower’s long-term senior unsecured non-credit enhanced debt rating, or (iv) if and only if such Rating Agency does not have in effect a rating described in the preceding clauses (i), (ii) or (iii), the Borrower’s “company” or “corporate credit” rating (or its equivalent) assigned by such Rating Agency.

“Fitch Rating” means, at any time, the Designated Rating issued by Fitch and then in effect.

“Level I Status” exists at any date if, (a) with respect to the Leverage-Based Pricing Grid, on such date, the Borrower’s Consolidated Leverage Ratio is less than 2.5:1.0 and (b) with respect to the Ratings-Based Pricing Grid, on such date, the Borrower has the following Designated Ratings: a Moody’s Rating of Baa1 or better, a Fitch Rating of BBB+ or better and an S&P Rating of BBB+ or better, subject to the last paragraph of this Pricing Schedule.

“Level II Status” exists at any date if, (a) with respect to the Leverage-Based Pricing Grid, on such date, (i) the Borrower has not qualified for Level I Status and (ii) the Borrower’s Consolidated Leverage Ratio is greater than or equal to 2.5:1.0 but less than 3.0 to 1.0 and (b) with respect to the Ratings-Based Pricing Grid, on such date, (i) the Borrower has not qualified for Level I Status and (ii) the Borrower has the following Designated Ratings: a Moody’s Rating of Baa2 or better, a Fitch Rating of BBB or better and an S&P Rating of BBB or better, subject to the last paragraph of this Pricing Schedule.

“Level III Status” exists at any date if, (a) with respect to the Leverage-Based Pricing Grid, on such date, (i) the Borrower has not qualified for Level I Status or Level II Status and (ii) the Borrower’s Consolidated Leverage Ratio is greater than or equal to 3.0:1.0 but less than 3.5 to 1.0 and (b) with respect to the Ratings-Based Pricing Grid, on such date, (i) the Borrower has not qualified for Level I Status or Level II Status and (ii) the Borrower has the following Designated Ratings: a Moody’s Rating of Baa3 or better, a Fitch Rating of BBB- or better and an S&P Rating of BBB- or better, subject to the last paragraph of this Pricing Schedule.

“Level IV Status” exists at any date if, (a) with respect to the Leverage-Based Pricing Grid, on such date, (i) the Borrower has not qualified for Level I Status, Level II Status or Level III Status and (ii) the Borrower’s Consolidated Leverage Ratio is greater than or equal to 3.5:1.0 but less than 4.0 to 1.0 and (b) with respect to the Ratings-Based Pricing Grid, on such date, (i) the Borrower has not qualified for Level I Status, Level II Status or Level III Status and (ii) the Borrower has the following Designated Ratings: a Moody’s Rating of Ba1 or better, a Fitch Rating of BB+ or better and an S&P Rating of BB+ or better, subject to the last paragraph of this Pricing Schedule.

“Level V Status” exists at any date if, with respect to the Leverage-Based Pricing Grid and the Ratings-Based Pricing Grid, on such date, the Borrower has not qualified for Level I Status, Level II Status, Level III Status or Level IV Status.

“Moody’s Rating” means, at any time, the Designated Rating issued by Moody’s and then in effect.

“S&P Rating” means, at any time, the Designated Rating issued by S&P, and then in effect.

“Status” means Level I Status, Level II Status, Level III Status, Level IV Status or Level V Status.

The Applicable Margin and the Applicable Fee Rate shall be determined in accordance with the foregoing table based on the Borrower’s Status as determined from its then-current Moody’s Rating, Fitch Rating and S&P Rating. The credit rating in effect on any date for the purposes of this Pricing Schedule is that in effect at the close of business on such date. The Borrower shall at all times maintain a Designated Rating from at least one of Moody’s, Fitch and S&P. If at any time the Borrower does not have a Designated Rating from any of Moody’s, Fitch or S&P, Level V Status shall exist.

Notwithstanding the foregoing, (i) if the Designated Ratings are split and all three ratings fall in different levels, the Applicable Margin and the Applicable Fee Rate shall be based upon the level indicated by the middle rating; (ii) if the Designated Ratings are split and two of the ratings fall in the same level (the “Majority Level”) and the third rating is in a different level, the Applicable Margin and the Applicable Fee Rate shall be based upon the Majority Level; (iii) if only two of the three Rating Agencies issue a Designated Rating, the higher of such ratings shall apply, provided that if the higher rating is two or more levels above the lower rating, the rating next below the higher of the two shall apply; (iv) if only one of the three Rating Agencies issues a Designated Rating, such rating shall apply; and (v) if the Designated Rating established by S&P, Moody’s or Fitch shall be changed (other than as a result of a change in the rating system of S&P, Moody’s or Fitch), such change shall be effective as of the date on which it is first announced by the applicable Rating Agency. If the rating system of S&P, Moody’s or Fitch shall change, or if any of S&P, Moody’s or Fitch shall cease to be in the business of rating corporate debt obligations, the Borrower and the Agent shall negotiate in good faith if necessary to amend this provision to reflect such changed rating system or the unavailability of Designated Ratings from such Rating Agencies and, pending the effectiveness of any such amendment, the Applicable Margin and the Applicable Fee Rate shall be determined by reference to the Designated Rating of such Rating Agency most recently in effect prior to such change or cessation.
