SECTION 2.03. Swingline Loans. (a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make loans to the Borrower (each such loan, a “Swingline Loan”) from time to time during the Revolving Credit Period in dollars, in an aggregate principal amount at any time outstanding that will not result in (i) the aggregate principal amount of outstanding Swingline Loans exceeding $100,000,000 or (ii) the Total Outstanding Amount exceeding the aggregate amount of the Commitments; provided that the Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan. Each Swingline Loan shall be in an aggregate principal amount that is an integral multiple of $1,000,000. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Swingline Loans.

(b) To request a Swingline Loan, the Borrower shall deliver a notice (a “Notice of Swingline Borrowing”) to the Administrative Agent by telephone or fax (and, in the case of telephonic notice, promptly confirmed by hand delivery or telecopy), not later than 2:00 P.M.

Each such notice shall be irrevocable and shall specify the requested date (which shall be a Domestic Business Day) and amount of the requested Swingline Loan and whether such Swingline Loan is to be a Base Rate Loan or a Money Market Rate Loan. The Administrative Agent will promptly advise the Swingline Lender of any such notice received from the Borrower. The Swingline Lender shall make each Swingline Loan available to the Borrower by means of a credit to the general deposit account of the Borrower with the Swingline Lender (or, in the case of a Swingline Loan made to finance the reimbursement of any amounts paid by any Issuing Bank upon any drawing under any Letter of Credit as provided in Section 2.04(c), by remittance to such Issuing Bank) by 3:00 P.M.

Any amounts received by the Swingline Lender from the Borrower (or other party on behalf of the Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Administrative Agent; any such amounts received by the Administrative Agent shall be promptly remitted by the Administrative Agent to the Lenders that shall have made their payments pursuant to this paragraph and to the Swingline Lender, as their interests may appear; provided, that any such payment so remitted shall be repaid to the Swingline Lender or to the Administrative 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 Swingline Loan pursuant to this paragraph shall not relieve the Borrower of any default in the payment thereof.

Upon receipt of a Notice of Issuance, the applicable Issuing Bank shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify each Lender of the contents thereof and of the amount of such Lender’s participation in such Letter of Credit.

(ii) The obligation of the applicable Issuing Bank to issue each Letter of Credit shall, in addition to the conditions precedent set forth in Section 3.02, be subject to the conditions precedent that such Letter of Credit shall be in such form and contain such terms as shall be reasonably satisfactory to such Issuing Bank and that the Borrower shall have executed and delivered such other customary instruments and agreements (which may include a letter of credit application) relating to such Letter of Credit as such Issuing Bank shall have reasonably requested. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the applicable Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control. The Borrower shall also pay to each Issuing Bank for its own account issuance, drawing, amendment, settlement and extension charges, if any, in the amounts and at the times as agreed between the Borrower and such Issuing Bank.

(iii) The extension or renewal of any Letter of Credit shall be deemed to be an issuance of such Letter of Credit, and if any Letter of Credit contains a provision pursuant to which it is deemed to be extended unless notice of termination is given by the Issuing Bank, the Issuing Bank shall timely give such notice of termination unless it has theretofore timely received a Notice of Issuance and the other conditions to issuance of a Letter of Credit have also theretofore been met with respect to such extension. Each Letter of Credit shall expire at or before the close of business on the date that is one year after such Letter of Credit is issued (or, in the case of any renewal or extension thereof, one year after such renewal or extension); provided that (i) a Letter of Credit may contain a provision pursuant to which it is deemed to be extended on an annual basis unless notice of termination is given by the Issuing Bank and (ii) in no event will a Letter of Credit expire (including pursuant to a renewal or extension thereof) on a date later than the Letter of Credit Termination Date.

(c) Payments; Reimbursement Obligations. (i) Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the applicable Issuing Bank shall notify the Administrative Agent and the Administrative Agent shall promptly notify the Borrower and each other Lender as to the amount to be paid as a result of such demand or drawing and the date such payment is to be made by the Issuing Bank (the

“Payment Date”). The Borrower shall be irrevocably and unconditionally obligated to reimburse the Issuing Bank for any amounts paid by the Issuing Bank upon any drawing under any Letter of Credit, without presentment, demand, protest or other formalities of any kind. Such reimbursement shall be made not later than 2:00 P.M. (New York City time) on the Payment Date, if the Borrower shall have received notice of its obligation to make such payment prior to 10:00 A.M.

(New York City time) on the day of receipt, or (B) the Domestic Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that if and to the extent any such reimbursement is not made by the Borrower in accordance with this clause (i) or clause (ii) below on the Payment Date, then (irrespective of when notice thereof is received by the Borrower), such reimbursement obligation shall bear interest, payable on demand, for each day from and including the Payment Date to but excluding the date such reimbursement obligation is paid in full at a rate per annum equal to the rate applicable to Base Rate Loans for such day.

(ii) If the Commitments are in effect on any Payment Date, all such amounts paid by the applicable Issuing Bank on such Payment Date and remaining unpaid by the Borrower after the date and time required by Section 2.04(c)(i) (a “Reimbursement Obligation”) shall, if and to the extent that the amount of such Reimbursement Obligation would be permitted as a Borrowing of Loans pursuant to Section 3.02, and unless the Borrower otherwise instructs the Administrative Agent by not less than one Domestic Business Day’s prior notice, convert automatically to Base Rate Loans on the date such Reimbursement Obligation arises. The Administrative Agent shall, on behalf of the Borrower (which hereby irrevocably directs the Administrative Agent so to act on its behalf), give notice no later than 12:00 Noon (New York City time) on such date requesting each Lender to make, and each Lender hereby agrees to make, a Base Rate Loan, in an amount equal to such Lender’s Percentage of the Reimbursement Obligation to which such notice relates. Each Lender shall make such Loan available to the Administrative Agent at its address referred to in Section 9.01 in immediately available funds, not later than 2:00 P.M. (New York City time), on the date specified in such notice. The Administrative Agent shall pay the proceeds of such Loans to the applicable Issuing Bank, which shall immediately apply such proceeds to repay the Reimbursement Obligation.

Domestic Business Days after the date of such demand and thereafter at a rate per annum equal to the Base Rate for each additional day. The Issuing Bank receives such payment as agent for and for the account of each Lender and will pay to each Lender ratably all amounts received from the Borrower for application in payment of its Reimbursement Obligations in respect of any Letter of Credit, but only to the extent such Lender has made payment to the Issuing Bank in respect of such Letter of Credit pursuant hereto; provided that in the event such payment received by the Issuing Bank is required to be returned, such Lender will return to the Issuing Bank any portion thereof previously distributed to it by the Issuing Bank.

(ii) None of the Lenders (including any Issuing Bank) or the Administrative Agent or any of their officers or directors or employees or agents shall be liable or responsible by reason of or in connection with the execution and delivery or transfer of or payment or failure to pay under any Letter of Credit, including any of the circumstances enumerated in subsection (d) above; provided that, notwithstanding Section 2.04(d), the Borrower shall have a claim for direct (but not indirect, consequential or punitive) damages suffered by it, to the extent finally determined by a court of competent jurisdiction to have been caused by (x) the Issuing Bank’s gross negligence or willful misconduct in determining whether documents presented under any Letter of Credit complied with the terms of such Letter of Credit or (y) the Issuing Bank’s failure to pay under any Letter of Credit after the presentation to it of documents strictly complying with the terms and conditions of the Letter of Credit. The parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(iii) Nothing in this subsection (e) is intended to limit the obligations of the Borrower under any other provision of this Agreement. To the extent the Borrower does not indemnify an Issuing Bank as required by this subsection, the Lenders agree to do so ratably in accordance with their Commitments.

(f) Stop Issuance Notice. If the Required Lenders reasonably determine at any time that the conditions set forth in Section 3.02 would not be satisfied in respect of the issuance of a Letter of Credit at such time, then the Required Lenders may request that the Administrative Agent issue a “Stop Issuance Notice”, and the Administrative Agent shall issue such notice to each Issuing Bank. Such Stop Issuance Notice shall be withdrawn upon a determination by the Required Lenders that the circumstances giving rise thereto no longer exist. No Letter of Credit shall be issued while a Stop Issuance Notice is in effect. The Required Lenders may request issuance of a Stop Issuance Notice only if there is a reasonable basis therefor, and shall consider reasonably and in good faith a request from the Borrower for withdrawal of the same on the basis that the conditions in Section 3.02 are satisfied, provided

that the Administrative Agent and the Issuing Banks may and shall conclusively rely upon any Stop Issuance Notice while it remains in effect.

(g) Termination of an Issuing Bank. The Borrower may terminate the status of any Issuing Bank as an “Issuing Bank” hereunder by providing a written notice thereof to such Issuing Bank, with a copy to the Administrative Agent. Any such termination shall become effective upon the earlier of (i) such Issuing Bank acknowledging receipt of such notice and (ii) the 10th Domestic Business Day following the date of the delivery thereof; provided that no such termination shall become effective until and unless the Letter of Credit Liabilities attributable to Letters of Credit issued by such Issuing Bank (or its affiliates) shall have been reduced to zero or cash collateralized (in an amount equal to 100% of such Letter of Credit Liabilities) in a manner approved in writing by such Issuing Bank, or other arrangements with respect to such Letter of Credit Liabilities approved in writing by such Issuing Bank shall have been made. At the time any such termination shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the terminated Issuing Bank pursuant to Section 2.10(b). Notwithstanding the effectiveness of any such termination, the terminated Issuing Bank shall remain a party hereto and shall continue to have all the rights of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such termination, but shall not issue any additional Letters of Credit.

(h) Issuing Bank Reports to the Administrative Agent. Unless otherwise agreed by the Administrative Agent, each Issuing Bank shall, in addition to its notification obligations set forth elsewhere in this Section, report in writing to the Administrative Agent (i) periodic activity (for such period or recurrent periods as shall be reasonably requested by the Administrative Agent) in respect of Letters of Credit issued by such Issuing Bank, including all issuances, extensions, amendments and renewals, all expirations and cancelations and all disbursements and reimbursements, (ii) reasonably prior to the time that such Issuing Bank issues, amends, renews or extends any Letter of Credit, the date of such issuance, amendment, renewal or extension, and the stated amount of the Letters of Credit issued, amended, renewed or extended by it and outstanding after giving effect to such issuance, amendment, renewal or extension (and whether the amounts thereof shall have changed), (iii) on each day on which such Issuing Bank makes any payment under a Letter of Credit, the date and amount of such payment, (iv) on any Business Day on which the Borrower fails to reimburse any amount required to be reimbursed to such Issuing Bank on such day in respect of a drawing under a Letter of Credit, the date of such failure and the amount due but not paid and (v) on any other Business Day, such other information as the Administrative Agent shall reasonably request as to the Letters of Credit issued by such Issuing Bank.

SECTION 2.05. Notice to Lenders; Funding of Loans. (a) Promptly after receiving a Notice of Revolving Borrowing, the Administrative Agent shall notify each Lender of the contents thereof and of such Lender’s share of such Revolving Borrowing and such Notice of Revolving Borrowing shall not thereafter be revocable by the Borrower.

(b) Before the later of 12:00 Noon (New York City time) or three hours after the receipt of a Borrowing Request on the date of each Revolving Borrowing, each Lender participating therein shall make available its share of such Borrowing, in Federal or other funds immediately available in New York City, to the Administrative Agent at its address specified in

or pursuant to Section 9.01. Unless the Administrative Agent determines that any applicable condition specified in Article 3 has not been satisfied, the Administrative Agent will make the funds so received from the Lenders available to the Borrower at the Administrative Agent’s aforesaid address.

(c) Unless the Administrative Agent shall have received notice from a Lender before 12:00 Noon (New York City time) on the date of any Revolving Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of any such Borrowing, the Administrative Agent may assume that such Lender has made such share available to the Administrative Agent on the date of such Borrowing in accordance with Section 2.05(b) and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such share available to the Administrative Agent, such Lender and, if such Lender shall not have done so within five Domestic Business Days of demand therefor by the Administrative Agent, the Borrower, each agrees to pay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) if such amount is repaid by the Borrower, a rate per annum equal to the higher of the Federal Funds Rate and the interest rate applicable to such Borrowing pursuant to Section 2.08 and (ii) if such amount is repaid by such Lender, the Federal Funds Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, the Borrower shall not be required to repay such amount and the amount so repaid by such Lender shall constitute such Lender’s Revolving Loan included in such Borrowing for purposes of this Agreement. Nothing in this subsection (c) shall relieve any Lender of its obligation to make Loans in accordance with the terms and conditions of this Agreement or relieve any Lender from responsibility for default by it in such obligation.

SECTION 2.06. Registry; Notes. (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 Revolving Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

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

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

(d) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a

promissory note payable to such Lender and its registered assigns and in a form approved by the Administrative Agent. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 9.06(b)) be represented by one or more promissory notes in such form payable to the payee named therein and its registered assigns.

SECTION 2.07. Maturity of Loans. (a) Each Revolving Loan shall mature, and the principal amount thereof shall be due and payable (together with interest accrued thereon), on the Termination Date.

(b) Each Swingline Loan shall mature, and the principal amount thereof shall be due and payable (together with interest accrued thereon), on the earlier of the Termination Date and the first date after such Swingline Loan is made that is the 15th or last day of a calendar month and is at least two Domestic Business Days after such Swingline Loan is made; provided that on each date that a Revolving Borrowing is made, the Borrower shall repay all Swingline Loans that were outstanding on the date such Borrowing was requested.

SECTION 2.08. Interest Rates. (a) Each Base Rate Loan (including each Base Rate Swingline Loan) shall bear interest on the outstanding principal amount thereof, for each day from the date such Loan is made to but excluding the date it becomes due, at a rate per annum equal to the sum of the Base Rate Margin for such day plus the Base Rate for such day.

(b) Each Money Market Rate Loan shall bear interest on the outstanding principal amount thereof, for each day from the date such Loan is made to but excluding the date it becomes due, at a rate per annum equal to the Money Market Rate for such day.

(c) Each Euro-Dollar Loan shall bear interest on the outstanding principal amount thereof, for each day during each Interest Period applicable thereto, at a rate per annum equal to the sum of the Euro-Dollar Margin for such day plus the Adjusted London Interbank Offered Rate applicable to such Interest Period.

(d) Interest on each Base Rate Revolving Loan shall be payable quarterly in arrears on each Quarterly Payment Date and on the Termination Date. Interest on each Swingline Loan shall be payable in arrears on the date on which such Loan becomes due and payable. Interest on each Euro-Dollar Loan shall be payable for each Interest Period on the last day thereof and, if such Interest Period is longer than three months, at intervals of three months after the first day thereof and, with respect to the principal amount of any Euro-Dollar Loan that is prepaid or converted to a Base Rate Loan, on the date of such prepayment or conversion.

(e) Any overdue principal of and interest on any Loan shall bear interest, payable on demand, for each day from and including the date payment thereof was due to but excluding the date of actual payment, at a rate per annum equal to the sum of 2% plus the interest rate applicable to Base Rate Loans for such day.

(f) The Administrative Agent shall determine each interest rate applicable to the Loans hereunder in accordance with the terms hereof. The Administrative Agent shall promptly notify the Borrower and the participating Lenders of each rate of interest so determined, and its determination thereof shall be conclusive in the absence of manifest error.

SECTION 2.09. Method of Electing Interest Rates. (a) The Loans included in each Revolving Borrowing shall bear interest initially at the type of rate specified by the Borrower in the applicable Notice of Revolving Borrowing. Thereafter, the Borrower may from time to time elect to change or continue the type of interest rate borne by the Loans included in such Borrowing (subject to Section 2.09(d) and the provisions of Article 8) as follows:

(i) if such Loans are Base Rate Loans, the Borrower may elect to convert such Loans to Euro-Dollar Loans as of any Euro-Dollar Business Day; and

(ii) if such Loans are Euro-Dollar Loans, the Borrower may elect to convert such Loans to Base Rate Loans as of any Domestic Business Day, or may elect to continue such Loans as Euro-Dollar Loans, as of the end of any Interest Period applicable thereto, for an additional Interest Period, subject to Section 2.14 if any such conversion is effective on any day other than the last day of an Interest Period applicable to such Loans.

Each such election shall be made by delivering a notice (a “Notice of Interest Rate Election”) to the Administrative Agent by telephone or fax (and, in the case of telephonic notice, promptly confirmed by hand delivery or fax), not later than the time that a Notice of Revolving Borrowing would be required under Section 2.02 if the Borrower were requesting a Revolving Borrowing consisting of Loans of the Type resulting from such election to be made on the effective date of such election. A Notice of Interest Rate Election may, if it so specifies, apply to only a portion of the aggregate principal amount of the relevant Borrowing; provided that (i) such portion is allocated ratably among the Loans comprising such Borrowing and (ii) the portion to which such Notice applies, and the remaining portion to which it does not apply, are each at least $10,000,000 (unless such portion is comprised of Base Rate Loans). If no such notice is timely received before the end of an Interest Period for any Borrowing of Euro-Dollar Loans, the Borrower shall be deemed to have elected that the Loans included in such Borrowing be converted to Base Rate Loans at the end of such Interest Period.

(b) Each Notice of Interest Rate Election shall specify:

(i) the Borrowing (or portion thereof) to which such notice applies;

(ii) the date on which the conversion or continuation selected in such notice is to be effective, which shall comply with clause (i) or (ii) of Section 2.09(a), as applicable;

(iii) if the Loans comprising such Group are to be converted, the new Type of Loans and, if the Loans resulting from such conversion are to be Euro-Dollar Loans, the duration of the next succeeding Interest Period applicable thereto; and

(iv) if such Loans are to be continued as Euro-Dollar Loans for an additional Interest Period, the duration of such additional Interest Period.

Each Interest Period specified in a Notice of Interest Rate Election shall comply with the provisions of the definition of Interest Period.

(c) Promptly after receiving a Notice of Interest Rate Election from the Borrower pursuant to Section 2.09, the Administrative Agent shall notify each Lender of the contents thereof and such notice shall not thereafter be revocable by the Borrower.

(d) The Borrower shall not be entitled to elect to convert any Loans to, or continue any Loans for an additional Interest Period as, Euro-Dollar Loans if (i) the aggregate principal amount of any Euro-Dollar Loans created or continued as a result of such election would be less than $10,000,000 or (ii) an Event of Default shall have occurred and be continuing when the Borrower delivers notice of such election to the Administrative Agent and the Administrative Agent or the Required Lenders shall have notified the Borrower that Euro-Dollar Loans will not be available while such Event of Default continues.

SECTION 2.10. Fees. (a) Commitment Fee. The Borrower shall pay to the Administrative Agent, for the account of the Lenders ratably in proportion to their Commitments, a commitment fee calculated for each day at the Commitment Fee Rate for such day (determined in accordance with the Pricing Schedule) on the aggregate unused amount of the Commitments on such day. For purposes of computing commitment fees, a Commitment of a Lender shall be deemed to be used to the extent of the outstanding Revolving Loans and Letter of Credit Liabilities of such Lender and participations in outstanding Swingline Loans that have been funded by such Lender (but unfunded participations in Swingline Loans shall be disregarded for such purpose). Such commitment fee shall accrue for each day from and including the Effective Date to but excluding the day on which the Commitments are reduced to zero.

(b) Letter of Credit Fees. The Borrower shall pay (i) to the Administrative Agent for the account of the Lenders ratably a letter of credit fee accruing daily on the aggregate undrawn amount of all outstanding Letters of Credit at a rate per annum equal to the Euro-Dollar Margin for such day and (ii) to each Issuing Bank for its own account, a letter of credit fronting fee accruing daily on the aggregate amount then available for drawing under all Letters of Credit issued by such Issuing Bank at the rate per annum mutually agreed between the Borrower and such Issuing Bank from time to time.

(c) Payments. Fees accrued for the account of the Lenders under this Section shall be payable quarterly in arrears on each Quarterly Payment Date and on the day on which the Commitments terminate in their entirety (and, if later, on the day on which the Credit Exposures are reduced to zero).

SECTION 2.11. Termination or Reduction of Commitments. (a) The Borrower may, upon at least three Domestic Business Days’ notice to the Administrative Agent, (i) terminate the Commitments at any time or (ii) ratably reduce from time to time by an aggregate amount of $25,000,000 or any larger integral multiple of $1,000,000, the aggregate amount of the Commitments; provided that the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.12, the Total Outstanding Amount would exceed the aggregate amount of the Commitments as a result thereof. For the avoidance of doubt, any notice of termination of the Commitments may state that such notice is conditioned upon the effectiveness of other credit facilities or the closing of one or more securities offerings, in which case such notice may be

revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified date) if such condition is not satisfied. Promptly after receiving a notice pursuant to this subsection, the Administrative Agent shall notify each Lender of the contents thereof.

(b) Unless previously terminated, the Commitments shall terminate in their entirety on the Termination Date.

SECTION 2.12. Optional Prepayments. (a) Subject in the case of Euro-Dollar Loans to Section 2.14, the Borrower may (i) upon notice to the Administrative Agent on or prior to the date of prepayment, prepay any Base Rate Loans or (ii) upon at least three Euro-Dollar Business Days’ notice to the Administrative Agent, prepay any Euro-Dollar Loans, in each case in whole at any time, or from time to time in part in amounts that would be permitted in the case of the making of a Revolving Borrowing comprised of Loans of the same Type or a Swingline Loan, as applicable. Each such optional prepayment shall be applied to prepay ratably the Loans of the several Lenders included in such Borrowing. Prepayments shall be accompanied by interest to the extent required by Section 2.08.

(b) Promptly after receiving a notice of prepayment pursuant to this Section, the Administrative Agent shall notify each Lender of the contents thereof and of such Lender’s ratable share of such prepayment, and such notice shall not thereafter be revocable by the Borrower; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.11, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.11.

SECTION 2.13. General Provisions as to Payments. (a) The Borrower shall make each payment of principal of and interest on the Loans and of fees hereunder not later than 12:00 Noon (New York City time) on the date when due, in Federal or other funds immediately available in New York City, without reduction by reason of any set-off, counterclaim or deduction of any kind (except as provided in Section 8.05). All such payments shall be made to the Administrative Agent at its address specified in or pursuant to Section 9.01, except that payments to be made directly to an Issuing Bank or the Swingline Lender as expressly provided herein shall be made directly to such Issuing Bank or the Swingline Lender, as applicable, and payments pursuant to Sections 2.14, 8.03, 8.05 and 9.03 shall be made directly to the Persons entitled thereto. The Administrative Agent will distribute each such payment received by the Administrative Agent for the account of any other Person to the appropriate recipient promptly following receipt thereof. Whenever any payment of principal of, or interest on, the Base Rate Loans or of fees shall be due on a day which is not a Domestic Business Day, the date for payment thereof shall be extended to the next succeeding Domestic Business Day. Whenever any payment of principal of, or interest on, the Euro-Dollar Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day falls in another calendar month, in which case the date for payment thereof shall be the next preceding Euro-Dollar Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such extended time.

(b) Unless the Borrower notifies the Administrative Agent before the date on which any payment is due to the Lenders hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance on such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that such payment shall not have been so made by the Borrower, each Lender shall repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate.

SECTION 2.14. Funding Losses. If the Borrower makes any payment of principal with respect to any Euro-Dollar Loan or any Euro-Dollar Loan is converted to a different type of Loan (whether such payment or conversion is pursuant to Article 2, 6 or 8 or otherwise) on any day other than the last day of the Interest Period applicable thereto, or if the Borrower fails (other than as a result of the failure of a Lender to fund a Loan required to be funded hereunder) to borrow, prepay, convert or continue any Euro-Dollar Loan after notice has been given to any Lender in accordance with Section 2.05, 2.09 or 2.12, the Borrower shall reimburse each Lender within 30 days after demand for any resulting loss or expense incurred by it, including any loss incurred in obtaining, liquidating or employing deposits from third parties, but excluding loss of margin for the period after such payment or conversion or failure to borrow, prepay, convert or continue; provided that such Lender shall have delivered to the Borrower a certificate as to the amount of such loss or expense, including in reasonable detail a description of the basis for such compensation and a calculation of such amount, which certificate shall be conclusive in the absence of manifest error.

SECTION 2.15. Computation of Interest and Fees. Interest based on the Prime Rate hereunder shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and paid for the actual number of days elapsed (including the first day but excluding the last day). All other interest and fees shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day).

SECTION 2.16. Change of Control. If a Change of Control shall occur, the Borrower will, within ten days after the occurrence thereof, give the Administrative Agent notice thereof, and the Administrative Agent shall promptly notify each Lender thereof. Such notice shall describe in reasonable detail the facts and circumstances giving rise thereto and the date of such Change of Control and each Lender may, by notice to the Borrower and the Administrative Agent given not later than fifty days after the date of such Change of Control, terminate its Commitment and declare its Loans (together with accrued interest thereon) and any other amounts payable hereunder for its account to be due and payable, in which case its Commitment shall terminate, and such Loans and other amounts shall become due and payable, in each case on the sixtieth day after the date of such Change of Control (or if such day is not a Domestic Business Day, the next succeeding Domestic Business Day), without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower. In the event that, after giving effect to any termination of Commitments and repayment of Loans under this Section 2.16, the Total Outstanding Amount shall exceed the aggregate Commitments remaining in effect, the Borrower shall make additional prepayments of Loans or cash collateralize, in a

manner approved in writing by the Administrative Agent and the Issuing Banks, an amount of the Letter of Credit Liabilities equal to such excess.

For purposes of this Section, the following terms have the following meanings:

A “Change of Control” shall occur if (i) any “person” or “group” of persons shall have acquired “beneficial ownership” (within the meaning of Section 13(d) or 14(d) of the Securities Exchange Act of 1934, as amended, and the applicable rules and regulations thereunder), of shares of Voting Stock representing 35% or more of the Voting Power of the Borrower, (ii) during any period of twenty-five consecutive months, commencing before or after the date of this Agreement, individuals who at the beginning of such twenty-five month period were members of the board of directors of the Borrower (together with any replacement or additional directors whose election was recommended by incumbent management of the Borrower or whose election, nomination or appointment to the board of directors of the Borrower was approved by a majority of directors then in office) cease to constitute a majority of the board of directors of the Borrower, or (iii) any Person or group of related Persons shall acquire all or substantially all of the assets of the Borrower; provided, that a Change of Control shall not be deemed to have occurred pursuant to clause (iii) above if the Borrower shall have merged or consolidated with or transferred all or substantially all of its assets to another corporation in compliance with the provisions of Section 5.02 and the surviving or successor or transferee corporation is no more leveraged than was the Borrower immediately prior to such event. For purposes of this definition, the term “leveraged” when used with respect to any corporation shall mean the percentage represented by the total assets of that corporation divided by its stockholders’ equity, in each case determined and as would be shown in a consolidated balance sheet of such corporation prepared in accordance with generally accepted accounting principles in the United States of America.

“Voting Power” as applied to the stock of any corporation means the total voting power represented by all outstanding Voting Stock of such corporation.

“Voting Stock” as applied to the stock of any corporation means stock of any class or classes (however designated) having ordinary voting power for the election of the directors of such corporation, other than stock having such power only by reason of the happening of a contingency.

SECTION 2.17. Optional Increase in Commitments. The Borrower may from time to time, by written notice to the Administrative Agent, executed by the Borrower and one or more financial institutions (any such financial institution referred to in this Section being called an “Increasing Lender”), which may include any Lender (it being understood that no Lender shall have any obligation to become an Increasing Lender), cause the Commitments of the Increasing Lenders to be increased (or cause Commitments to be extended by the Increasing Lenders, as the case may be) in an amount for each Increasing Lender set forth in such notice; provided that (i) the amount of any such increase in the aggregate Commitments shall be not less than $25,000,000, (ii) the aggregate amount of increases in Commitments made pursuant to this Section shall not exceed $1,000,000,000 and (iii) each Increasing Lender, if not already a Lender hereunder, shall be subject to the approval of the Administrative Agent and each Issuing Bank

(which approval shall not be unreasonably withheld, conditioned or delayed) and shall execute all such documentation as the Administrative Agent and the Borrower shall specify to evidence the Commitment of such Increasing Lender and its status as a Lender hereunder. Such notice shall set forth the date (the “Increase Effective Date”) on which such increase is requested to become effective (which shall not be less than five Domestic Business Days or more than 45 days after the date of such notice). On the Increase Effective Date, (A) the aggregate principal amount of the Revolving Loans outstanding (the “Initial Loans”) immediately prior to giving effect to the commitment increase on the Increase Effective Date shall be deemed to be repaid, (B) after the effectiveness of the commitment increase, the Lenders shall be deemed to have made new Revolving Loans (the “Subsequent Borrowings”) of the types and in an aggregate principal amount equal to the aggregate principal amount of the Initial Loans and, in the case of Eurodollar Revolving Loans, for the Interest Periods equal to the remaining portions of the Interest Periods in effect prior to such deemed repayment, (C) each Lender shall pay to the Administrative Agent in same day funds an amount equal to the difference, if positive, between (x) such Lender’s Percentage (calculated after giving effect to the commitment increase) of the Subsequent Borrowings and (y) such Lender’s Percentage (calculated without giving effect to the commitment increase) of the Initial Loans, (D) after the Administrative Agent receives the funds specified in clause (C) above, the Administrative Agent shall pay to each Lender the portion of such funds that is equal to the difference, if positive, between (1) such Lender’s Percentage (calculated without giving effect to the commitment increase) of the Initial Loans and (2) such Lender’s Percentage (calculated after giving effect to the commitment increase) of the amount of the Subsequent Borrowings, (E) each Lender (including each Increasing Lender) shall be deemed to hold its Percentage of each Subsequent Borrowing (each calculated after giving effect to the commitment increase) and (F) the Borrower shall pay each Lender (other than any Increasing Lender that was not a Lender before giving effect to the Commitment increase) any and all accrued but unpaid interest on the Initial Loans. The deemed payments made pursuant to clause (A) above in respect of each Eurodollar Revolving Loan shall be subject to indemnification by the Borrower pursuant to the provisions of Section 2.14 if the Increase Effective Date occurs other than on the last day of the Interest Period relating thereto (it being agreed that Lenders will be entitled to break-funding compensation only with respect to the net amounts by which their Eurodollar Revolving Loans shall have been reduced as a result of the transactions provided for in the immediately preceding sentence). Notwithstanding the foregoing, no increase in the Commitments (or in any Commitment of any Lender) or addition of an Increasing Lender shall become effective under this Section unless (x) on the date of such increase, the conditions set forth in Section 3.02(b) and (c) shall be satisfied (with all references in such paragraphs to a Credit Event being deemed to be references to such increase) and the Administrative Agent shall have received a certificate to that effect dated such date and executed by a financial officer of the Borrower, and (y) the Administrative Agent shall have received (with sufficient copies for each of the Lenders) documents consistent with those delivered pursuant to Section 3.01(b) and (d) as to the corporate power and authority of the Borrower to borrow hereunder after giving effect to such increase.

SECTION 2.18. Extension Option. The Borrower may, by written notice to the Administrative Agent (which shall promptly deliver a copy to each of the Lenders) not less than 30 days and not more than 90 days prior to any anniversary of the Effective Date (but on not more than two occasions during the term of this Agreement), request that the Lenders extend the Termination Date for an additional period of one year. Each Lender shall, by notice to the

Borrower and the Administrative Agent given not later than the 20th day after the date of the Administrative Agent’s receipt of the Borrower’s notice, advise the Borrower whether or not it agrees to the requested extension (each Lender agreeing to a requested extension being called a “Consenting Lender” and each Lender declining to agree to a requested extension being called a “Declining Lender”). Any Lender that has not so advised the Borrower and the Administrative Agent by such day shall be deemed to have declined to agree to such extension and shall be a Declining Lender. If Lenders constituting the Required Lenders shall have agreed to a Termination Date extension request, then the Termination Date shall, as to the Consenting Lenders, be extended to the first anniversary of the Termination Date theretofore in effect (the Termination Date in effect prior to such extension being called the “Existing Termination Date”). The decision of any Lender to agree or withhold agreement to any extension request shall be at the sole discretion of such Lender. The Commitment of any Declining Lender shall terminate on the Existing Termination Date. The principal amount of any outstanding Loans made by Declining Lenders, together with any accrued interest thereon and any accrued fees and other amounts payable to or for the accounts of such Declining Lenders hereunder, shall be due and payable on the Existing Termination Date, and on the Existing Termination Date the Borrower shall also make such other prepayments of the Loans as shall be required in order that, after giving effect to the termination of the Commitments of, and all payments to, Declining Lenders pursuant to this sentence, the Total Outstanding Amount shall not exceed the aggregate Commitments. Notwithstanding the foregoing provisions of this paragraph, the Borrower shall have the right, pursuant to Sections 8.06(b) (and subject to the consent of the Administrative Agent, each Issuing Bank and the Swingline Lender, which consent shall not be unreasonably withheld, conditioned or delayed), at any time prior to the Existing Termination Date, to replace a Declining Lender with a Lender or other financial institution that will agree to a Termination Date extension request, and any such replacement Lender shall for all purposes constitute a Consenting Lender. Notwithstanding the foregoing, no extension of the Termination Date pursuant to this paragraph shall become effective unless (i) the Administrative Agent shall have received documents consistent with those delivered under Section 3.01(d) as to the corporate power and authority of the Borrower to effect such extension and (ii) the Administrative Agent shall have received a certificate executed by a financial officer of the Borrower, dated as of the anniversary of the Effective Date that immediately follows the date on which the Borrower delivers the applicable Termination Date extension request, stating that (A) as of such date, no Default exists and (B) the representations and warranties of the Borrower contained in Article 4 of this Agreement are true in all material respects on and as of such date (except to the extent any such representations or warranties are limited to an earlier date, in which case such representations and warranties shall be true in all material respects as of such earlier date).

SECTION 2.19. Defaulting Lenders. Notwithstanding any provision herein to the contrary, if any Lender becomes a Defaulting Lender, then the provisions set forth in the following paragraphs (a) through (f) shall apply for so long as such Lender is a Defaulting Lender:

(a) commitment fees shall cease to accrue on the unused portion of the Commitment of such Defaulting Lender pursuant to Section 2.10(a);

(b) the Commitment and Credit Exposure of such Defaulting Lender shall not be included in determining whether all Lenders (or each Lender) or the Required Lenders have

taken or may take any action hereunder (including any consent to any amendment, waiver or other modification pursuant to Section 9.05); provided, that this clause (b) shall not apply to the vote of a Defaulting Lender in the case of an amendment, waiver or other modification providing for an increase in such Defaulting Lender’s Commitment, providing for an extension of such Defaulting Lender’s Commitment (other than in determining whether the Required Lenders have consented to the extension of the Termination Date under Section 2.18) or requiring the consent of each Lender affected thereby (including pursuant to Sections 9.05(a)(ii) and (iii)) if such Defaulting Lender is an affected Lender;

(c) if any Swingline Liabilities or Letter of Credit Liabilities exist at the time such Lender becomes a Defaulting Lender, then the following paragraphs (i) through (v) shall apply:

(i) all or any part of the Swingline Liabilities and Letter of Credit Liabilities of such Defaulting Lender shall be reallocated (effective as of the date such Lender becomes a Defaulting Lender) among the non-Defaulting Lenders in accordance with their respective Percentages (for the purposes of such reallocation, such Defaulting Lender’s Commitment shall be disregarded in determining the non-Defaulting Lenders’ respective Percentages), but only to the extent that (A) the sum of all non-Defaulting Lenders’ Outstanding Amounts plus such Defaulting Lender’s Swingline Liabilities and Letter of Credit Liabilities does not exceed the total of all non-Defaulting Lenders’ Commitments, and (B) after giving effect to any such reallocation, no non-Defaulting Lender’s Outstanding Amount shall exceed such non-Defaulting Lender’s Commitment;

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall, within three Business Days following the Borrower’s receipt of written notice from the Administrative Agent, (A) first, prepay such Defaulting Lender’s Swingline Liabilities and (B) second, cash collateralize, for the benefit of the applicable Issuing Banks only, the Borrower’s obligations corresponding to such Defaulting Lender’s Letter of Credit Liabilities remaining after giving effect to any partial reallocation pursuant to clause (i) above in a manner approved in writing by the Administrative Agent for so long as such Letter of Credit Liabilities are outstanding;

(iii) if the Borrower cash collateralizes any portion of such Defaulting Lender’s Letter of Credit Liabilities pursuant to clause (ii) above, the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.10(b) with respect to such portion of such Defaulting Lender’s Letter of Credit Liabilities during the period such Letter of Credit Liabilities are cash collateralized;

(iv) if all or any portion of such Defaulting Lender’s Letter of Credit Liabilities is reallocated pursuant to clause (i) above, then all Letter of Credit participation fees that otherwise would have been payable to such Defaulting Lender under Section 2.10(b) with respect to such Defaulting Lender’s reallocated Letter of Credit Liabilities shall be payable to the non-Defaulting Lenders in accordance with such non-Defaulting Lenders’ Percentages after giving effect to such reallocation; and

(v) if all or any portion of such Defaulting Lender’s Letter of Credit Liabilities is neither reallocated nor cash collateralized pursuant to clause (i) or (ii) above, then, without prejudice to any rights or remedies of any Issuing Bank or any other Lender hereunder, all Letter of Credit participation fees that otherwise would have been payable to such Defaulting Lender under Section 2.10(b) with respect to such Defaulting Lender’s unreallocated Letter of Credit Liabilities shall be payable to the Issuing Banks, ratably based on the portion of such Letter of Credit Liabilities attributable to Letters of Credit issued by each Issuing Bank, until and to the extent that such Letter of Credit Liabilities are reallocated and/or cash collateralized pursuant to clause (i) or (ii) above;

(d) so long as such Lender is a Defaulting Lender, the Swingline Lender shall not be required to fund any Swingline Loan and no Issuing Bank shall be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure and the Defaulting Lender’s then outstanding Letter of Credit Liabilities will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 2.19(c), and participating interests in any newly made Swingline Loan or any newly issued or increased Letter of Credit shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.19(c)(i) (and such Defaulting Lender shall not participate therein);

(e) in the event that the Administrative Agent, the Borrower, the Swingline Lender and each Issuing Bank agree that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the Swingline Liabilities and Letter of Credit Liabilities of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment, and on such date such Lender shall purchase at par such of the Revolving Loans and other funded credit exposures of the other Lenders as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans and funded exposures in accordance with its Percentage; and

(f) the rights and remedies against, and with respect to, a Defaulting Lender under this Section 2.19 are in addition to, and cumulative and not in limitation of, all other rights and remedies that the Borrower, the Administrative Agent, each Lender, each Issuing Bank or the Swingline Lender may at any time have against, or with respect to, such Defaulting Lender.

Any such funds held as collateral by the Administrative Agent shall be held for the satisfaction of the reimbursement obligations of the Borrower for the aggregate Letter of Credit Liabilities at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders having more than 50% of the Letter of Credit Liabilities), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Domestic Business Days after all Events of Default have been cured or waived.

Each Lender irrevocably appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with all such powers as are reasonably incidental thereto.

SECTION 7.02. Administrative Agent and Affiliates. The bank serving as the Administrative Agent shall have the same rights and powers under this Agreement in its capacity as a Lender as any other Lender and may exercise or refrain from exercising the same as though it were not the Administrative Agent. Such bank and its affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower or any Subsidiary or affiliate of the Borrower as if it were not the Administrative Agent hereunder.

SECTION 7.03. Action by Administrative Agent. The obligations of the Administrative Agent hereunder are only those expressly set forth herein. Without limiting the generality of the foregoing, the Administrative Agent shall not be required to take any action with respect to any Default, except as expressly provided in Article 6.

SECTION 7.04. Consultation with Experts. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or

omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts.

SECTION 7.05. Liability of Administrative Agent. None of the Administrative Agent, its affiliates or its directors, officers, agents or employees shall be liable for any action taken or not taken by it in connection herewith (i) with the consent or at the request of the Required Lenders (or such different number of Lenders as any provision hereof expressly requires for such consent or request) or (ii) in the absence of its own gross negligence or willful misconduct or a material breach by the Administrative Agent of the express terms of this Agreement, as determined by a final judgment of a court of competent jurisdiction; provided that the provisions of this sentence are for the sole benefit of the Administrative Agent and shall not release any Lender from liability it would otherwise have to the Borrower. None of the Administrative Agent, its affiliates or its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into or verify (i) any statement, warranty or representation made in connection with this Agreement or any borrowing or any issuance of a Letter of Credit hereunder; (ii) the performance or observance of any of the covenants or agreements of the Borrower; (iii) the satisfaction of any condition specified in Article 3 except receipt of items required to be delivered to the Administrative Agent; or (iv) the validity, effectiveness or genuineness of this Agreement or any other instrument or writing furnished in connection herewith. The Administrative Agent shall not incur any liability by acting in reliance upon any notice, consent, certificate, statement or other writing (which may be a bank wire, facsimile or similar writing) believed by it to be genuine or to be signed by the proper party or parties. Without limiting the generality of the foregoing, the use of the term “agent” in this Agreement with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom and is intended to create or reflect only an administrative relationship between independent contracting parties.

SECTION 7.06. Indemnification. The Lenders severally agree, ratably in proportion to their Credit Exposures, to indemnify the Administrative Agent and each Issuing Bank, their respective affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the Borrower) against any cost, expense (including counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct or a material breach by the Administrative Agent of the express terms of this Agreement, as determined by a final judgment of a court of competent jurisdiction) that such indemnitees may suffer or incur in connection with this Agreement or any Letter of Credit or any action taken or omitted by such indemnitees hereunder or thereunder.

SECTION 7.07. Credit Decision. Each Lender acknowledges that it has, independently and without reliance on the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance on the Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking any action under this Agreement.

SECTION 7.08. Successor Administrative Agent. The Administrative Agent may resign at any time by giving notice thereof to the Lenders and the Borrower. Upon any such resignation, the Borrower shall have the right to appoint a successor Administrative Agent from among the Lenders, subject to the approval of the Required Lenders, which shall not be unreasonably withheld. If no successor Administrative Agent shall have been so appointed by the Borrower and approved by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent gives notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be a commercial bank organized or licensed under the laws of the United States or of any State thereof and having a combined capital and surplus of at least $100,000,000. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. After any retiring Administrative Agent resigns as Administrative Agent hereunder, the provisions of this Article shall inure to its benefit as to actions taken or omitted to be taken by it while it was Administrative Agent.

SECTION 7.09. Administrative Agent’s Fee. The Borrower shall pay to the Administrative Agent for its own account fees in the amounts and at the times previously agreed upon by the Borrower and the Administrative Agent.

SECTION 7.10. Other Agents. None of the Documentation Agents and the Syndication Agent, in their capacities as such, shall have any duties or obligations of any kind under this Agreement.

ARTICLE 8

Change in Circumstances

SECTION 8.01. Basis for Determining Interest Rate Inadequate or Unfair. If on or before the first day of any Interest Period for any Euro-Dollar Borrowing:

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

(b) Lenders having at least 50% in aggregate amount of the Commitments advise the Administrative Agent that the London Interbank Offered Rate for such Interest Period as determined by the Administrative Agent will not adequately and fairly reflect the cost to such Lenders of funding their Euro-Dollar Loans for such Interest Period,

the Administrative Agent shall forthwith give notice thereof to the Borrower and the Lenders, whereupon until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such suspension no longer exist, (i) the obligations of the Lenders to make Euro-Dollar Loans, or to continue or convert outstanding Loans as or into Euro-Dollar

Loans, shall be suspended and (ii) each outstanding Euro-Dollar Loan shall be converted into a Base Rate Loan on the last day of the then current Interest Period applicable thereto. Unless the Borrower notifies the Administrative Agent at least two Domestic Business Days before the date of any affected Borrowing for which a Notice of Revolving Borrowing has previously been given that it elects not to borrow on such date, such Borrowing shall instead be made as a Base Rate Borrowing.

SECTION 8.02. Illegality. (a) If, on or after the date hereof, any Change in Law shall make it unlawful or impossible for any Lender (or its applicable lending office) to make, maintain or fund its Euro-Dollar Loans and such Lender shall so notify the Administrative Agent, the Administrative Agent shall forthwith give notice thereof to the other Lenders and the Borrower, whereupon until such Lender notifies the Borrower and the Administrative Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Lender to make Euro-Dollar Loans, or to convert outstanding Loans into Euro-Dollar Loans or continue outstanding Loans as Euro-Dollar Loans, shall be suspended. Before giving any notice to the Administrative Agent pursuant to this Section, such Lender shall designate a different lending office if such designation will avoid the need for giving such notice and will not, in the judgment of such Lender, be otherwise disadvantageous to such Lender.

(b) If such notice is given, each Euro-Dollar Loan of such Lender then outstanding shall be converted to a Base Rate Loan either (a) on the last day of the then current Interest Period applicable to such Euro-Dollar Loan if such Lender may lawfully continue to maintain and fund such Loan as a Euro-Dollar Loan to such day or (b) immediately if such Lender shall determine that it may not lawfully continue to maintain and fund such Loan as a Euro-Dollar Loan to such day. Interest and principal on any such Base Rate Loan shall be payable on the same dates as, and on a pro rata basis with, the interest and principal payable on the related Euro-Dollar Loans of the other Lenders.

SECTION 8.03. Increased Cost and Reduced Return. (a) If any Change in Law shall:

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

(ii) impose on any Lender or any Issuing Bank or the London interbank market any other condition (other than with respect to Taxes) affecting this Agreement or Euro-Dollar Loans made by such Lender or any Letter of Credit or participation therein; or

(iii) subject any Recipient to any Taxes on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto (other than (A) Indemnified Taxes, (B) Other Connection Taxes (x) imposed on (or measured by) gross or net income (however denominated), profits or revenue (including value-added or similar Taxes) or (y) that are franchise Taxes

or branch profits Taxes and (C) Excluded Taxes described in paragraphs (a) through (f) of the definition of Excluded Taxes);

and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, continuing, converting into or maintaining any Euro-Dollar Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender, such Issuing Bank or such other Recipient of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender, such Issuing Bank or such other Recipient hereunder (whether of principal, interest or otherwise), then subject to paragraphs (c) and (d) of this Section, the Borrower will pay to such Recipient such additional amount or amounts as will compensate such Recipient for such additional costs incurred or reduction suffered.

(b) If any Lender or any Issuing Bank determines in good faith that any Change in Law regarding capital or liquidity requirements has the effect of reducing the rate of return on such Lender’s or such Issuing Bank’s capital or on the capital of such Lender’s or such Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by such Issuing Bank, to a level below that which such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuing Bank’s policies and the policies of such Lender’s or such Issuing Bank’s holding company with respect to capital adequacy and liquidity), then from time to time, subject to paragraphs (c) and (d) of this Section, the Borrower will pay to such Lender or such Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company for any such reduction suffered; provided, that such Lender or such Issuing Bank is generally seeking, or intends generally to seek, compensation from similarly situated borrowers under similar credit facilities (to the extent such Lender or Issuing Bank has the right under such similar credit facilities to do so) with respect to such Change in Law regarding capital or liquidity requirements.

(c) A certificate of a Lender or an Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or such Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section, including in reasonable detail a description of the basis for such claim for compensation and an explanation of how such amount or amounts were determined, shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate within 30 days after receipt thereof.

(d) Failure or delay on the part of any Lender or any Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation; provided, that the Borrower shall not be required to compensate a Lender or an Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than 180 days prior to the date that such Lender or such Issuing Bank, as the case may be, notifies the Borrower in writing of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or such Issuing Bank’s intention to claim compensation therefor; provided further, that if the Change in Law giving rise to such

increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

SECTION 8.04. Base Rate Loans Substituted for Affected Euro-Dollar Loans. If (i) the obligation of any Lender to make, or to continue or convert outstanding Loans as or to, Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii) any Lender has demanded compensation under Section 8.03 with respect to its Euro-Dollar Loans and the Borrower shall, by at least five Euro-Dollar Business Days’ prior notice to such Lender through the Administrative Agent, have elected that the provisions of this Section shall apply to the Lender demanding such compensation, then, unless and until such Lender notifies the Borrower that the circumstances giving rise to such suspension or demand for compensation no longer exist, all Loans which would otherwise be made by such Lender as (or continued as or converted to) Euro-Dollar Loans shall instead be Base Rate Loans on which interest and principal shall be payable contemporaneously with the related Euro-Dollar Loans of the other Lenders. If such Lender notifies the Borrower that the circumstances giving rise to such suspension or demand for compensation no longer exist, the principal amount of each such Base Rate Loan shall, subject to Section 8.02, be converted into a Euro-Dollar Loan on the first day of the next succeeding Interest Period applicable to the related Euro-Dollar Loans of the other Lenders.

SECTION 8.05. Taxes. (a) Withholding of Taxes; Gross-Up. Each payment by the Borrower hereunder shall be made without withholding for any Taxes, unless such withholding is required by any law. If any Withholding Agent determines, in its sole discretion exercised in good faith, that it is so required to withhold Taxes from any such payment, then such Withholding Agent may so withhold and shall timely pay the full amount of withheld Taxes to the relevant Governmental Authority in accordance with applicable law. If such Taxes are Indemnified Taxes, then the amount payable by the Borrower shall be increased as necessary so that, net of such withholding (including such withholding for Indemnified Taxes applicable to additional amounts payable under this Section 8.05(a)), the applicable Recipient receives the amount it would have received had no such withholding for Indemnified Taxes been made.

(b) Payment of Other Taxes by the Borrower. The Borrower shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes by the Borrower to a Governmental Authority pursuant to this Section 8.05, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(d) Indemnification by the Borrower. The Borrower shall indemnify each Recipient for any Indemnified Taxes that are paid or payable (without duplication) by such Recipient in connection with this Agreement (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 8.05(d)) 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 that the Borrower shall not be required to indemnify a Recipient pursuant to this Section 8.05(d) for any

Indemnified Taxes unless such Recipient notifies the Borrower of the indemnification claim for such Indemnified Taxes no later than 180 days after the date on which such Recipient has made payment of such Indemnified Taxes. The indemnity under this Section 8.05(d) shall be paid within 20 days after the Recipient delivers to the Borrower a certificate stating the amount of any Indemnified Taxes so paid or payable by such Recipient and describing the basis for the indemnification claim (including how such amounts were determined). Such certificate shall be conclusive of the amount so paid or payable absent manifest error. Such Recipient shall deliver a copy of such certificate to the Administrative Agent.

(e) Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent for (i) any Taxes (but, in the case of any Indemnified Taxes, only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so) attributable to such Lender and (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 9.06(g) relating to the maintenance of a Participant Register, in each case that are paid or payable by the Administrative Agent in connection with this Agreement 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. The indemnity under this Section 8.05(e) shall be paid within 10 days after the Administrative Agent delivers to the applicable Lender a certificate stating the amount of Taxes so paid or payable by the Administrative Agent. Such certificate shall be conclusive of the amount so paid or payable absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under this Agreement or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this Section 8.05(e) to the extent such amount shall not have been paid as provided herein.

(f) Status of Lenders. (i) Any Lender (which, solely for purposes of Section 8.05(f) and Section 8.05(g), shall include the Administrative Agent) that is entitled to an exemption from, or reduction of, withholding Tax with respect to any payments under this Agreement shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without, or at a reduced rate of, withholding. In addition, any Lender, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to any withholding (including backup withholding) or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 8.05(f)(ii)(A) through (E) and Section 8.05(g) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. Upon the reasonable request of the Borrower or the Administrative Agent, any Lender shall update any form or certification previously delivered pursuant to this Section 8.05(f) or Section 8.05(g). If any form or certification previously delivered pursuant to this Section 8.05(f) or Section 8.05(g) expires or becomes obsolete or

inaccurate in any respect with respect to a Lender, such Lender shall promptly (and in any event within 10 days after such expiration, obsolescence or inaccuracy) notify the Borrower and the Administrative Agent in writing of such expiration, obsolescence or inaccuracy and update the form or certification if it is legally eligible to do so.

(ii) Without limiting the generality of the foregoing, any Lender shall, if it is legally eligible to do so, deliver to the Borrower and the Administrative Agent (in such number of copies reasonably requested by the Borrower and the Administrative Agent) on or prior to the date on which such Lender becomes a party hereto (and from time to time therafter upon the reasonable request of the Borrower or the Administrative Agent), duly completed and executed originals of whichever of the following is applicable:

(A) in the case of a Lender that is a U.S. Person, IRS Form W-9 certifying that such Lender is exempt from U.S. Federal backup withholding tax;

(B) in the case of a Non-U.S. Lender claiming the benefits of an income tax treaty to which the United States is a party (1) with respect to payments of interest under this Agreement, 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 (2) with respect to any other applicable payments under this Agreement, 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;

(D) in the case of a Non-U.S. Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code both (1) IRS Form W-8BEN and (2) a certificate substantially in the form of Exhibit C (a “U.S. Tax Certificate”) to the effect that such Lender is neither (a) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (b) a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code or (c) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code;

(E) in the case of a Non-U.S. Lender that is not the beneficial owner of payments made under this Agreement (including a partnership or a participating Lender) (1) an IRS Form W-8IMY on behalf of itself and (2) the relevant forms prescribed in clauses (A), (B), (C), (D), (E) and (F) of this paragraph (f)(ii) that would be required of each such beneficial owner or partner of such partnership if such beneficial owner or partner were a Lender; provided, however, that if the Lender is a partnership and one or more of its direct or indirect partners are claiming the exemption for portfolio interest under Section 881(c) of the Code, such Lender may provide a U.S. Tax Certificate on behalf of such partners; or

(F) any other form prescribed by law as a basis for claiming exemption from, or a reduction of, U.S. Federal withholding Tax together with such supplementary documentation necessary to enable the Borrower or the Administrative Agent to determine the amount of Tax (if any) required by law to be withheld.

(g) FATCA. If a payment made to a Lender hereunder would be subject to U.S. Federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA, to determine that such Lender has or has not complied with such Lender’s obligations under FATCA and, as necessary, to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 8.05(g), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(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 8.05 (including by payment of additional amounts pursuant to this Section 8.05), it shall, within 45 days after receiving such refund, 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 any 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 to such indemnifying party pursuant to the previous sentence (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (h) the payment of which would place such indemnified party in a less favorable net after-Tax position than it would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This paragraph (h) shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes which it deems confidential) to the indemnifying party or any other Person.

(i) Issuing Bank. For purposes of this Section 8.05, the term “Lender” includes any Issuing Bank.

SECTION 8.06. Substitution of Lender. (a) Designation of a Different Lending Office. If any Lender requests compensation under Section 8.03, or the Borrower is or will be 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 8.05, then such Lender shall (at the request of the Borrower) use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the reasonable judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 8.03 or 8.05, as the case may be, in the future, and (ii) would not subject such Lender

to any material unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) If (i) the obligation of any Lender to make or to convert or continue outstanding Loans as or into Euro-Dollar Loans has been suspended pursuant to Section 8.02, (ii) any Lender has demanded compensation under Section 8.03 or the Borrower is or will be 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 8.05, (iii) any Lender has become a Defaulting Lender or a Declining Lender or (iv) any Lender refuses to consent to any proposed amendment, modification, waiver or consent with respect to any provision hereof that requires the unanimous approval of all Lenders, or the approval of each of the Lenders affected thereby (in each case in accordance with Section 9.05), and the consent of the Required Lenders shall have been obtained with respect to such amendment, modification, waiver or consent, then the Borrower shall have the right, upon notice to such Lender and the Administrative Agent, to designate a substitute financial institution or financial institutions (which may be one or more of the Lenders) to purchase for cash, pursuant to an Assignment and Assumption Agreement, the outstanding Revolving Loans and funded participations in Letter of Credit drawings and Swingline Loans of such Lender and assume the Commitment of such Lender, without recourse to or warranty by, or expense to, such Lender, for a purchase price equal to the principal amount of all of such Lender’s outstanding Revolving Loans and funded participations in Letter of Credit drawings and Swingline Loans plus any accrued but unpaid interest thereon and accrued but unpaid fees for the account of such Lender hereunder plus such amount, if any, as would be payable pursuant to Section 2.14 if the outstanding Revolving Loans of such Lender were prepaid in their entirety on the date of consummation of such assignment provided that the Borrower shall have received the prior written consent of the Administrative Agent with respect to any assignee that is not already a Lender hereunder (and if a Commitment is being assigned, each Issuing Bank), which consent shall not unreasonably be withheld, conditioned or delayed.

SECTION 8.07. Notice Mandatory. The Administrative Agent or the affected Lender, as the case may be, shall promptly give notice to the Borrower when circumstances which gave rise to a suspension of the obligations of the Lenders or a Lender to make or maintain Euro-Dollar Loans pursuant to Section 8.01 or 8.02, or to a demand for compensation under Section 8.03 or 8.05, no longer exist.

(b) The Borrower agrees to indemnify the Administrative Agent, each Issuing Bank, each Lender, their respective affiliates and the respective directors, officers, agents and employees of the foregoing (each an “Indemnitee”) and hold each Indemnitee harmless from and against any and all liabilities, losses, damages, costs and expenses of any kind, including reasonable fees and disbursements of counsel, which may be incurred by such Indemnitee in connection with any investigative, administrative or judicial proceeding (whether or not such Indemnitee shall be designated a party thereto) brought or threatened relating to or arising out of this Agreement or any actual or proposed use of proceeds of Loans or Letters of Credit hereunder; provided that (i) no Indemnitee shall have the right to be indemnified hereunder for its own gross negligence or willful misconduct or for its material breach of the express terms of this Agreement, in each case as determined by final judgment of a court of competent jurisdiction; (ii) the Borrower shall not, in connection with any such proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate law firm at any one time for the Indemnitees (which shall be selected by the Administrative Agent after consultation with the Borrower); provided, that in the case of a conflict of interest where the Indemnitee affected by such conflict informs the Borrower of such conflict, the Borrower shall be responsible for the reasonable fees and expenses of one firm of counsel for each such affected Indemnitee; (iii) each Indemnitee shall consult with the Borrower from time to time at the request of the Borrower regarding the conduct of the defense in any such proceeding; and (iv) the Borrower shall not be obligated to pay an amount of any settlement entered into without its consent (which shall not be unreasonably withheld.

(c) To the extent permitted by applicable law, no party hereto shall assert, and each party hereto hereby waives, any claim against any other party hereto, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, any Loan or Letter of Credit or the use of proceeds thereof; provided, that nothing in this paragraph shall limit the indemnification obligations of the Borrower under Section 9.03(b) with respect to any special, indirect, consequential or punitive damages that may be awarded against any Indemnitee in favor of any third party. The Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for any damages from the use by unintended recipients of information obtained by electronic means; provided that the foregoing shall not apply to the extent such damages are found by a final judgment of a court of competent jurisdiction to have arisen from the willful misconduct or gross negligence of such Indemnitee or the material breach by such Indemnitee of its agreements in Section 9.13.

SECTION 9.04. Sharing. Each Lender agrees that if it shall, by exercising any right of set-off or counterclaim or otherwise, receive payment of a proportion of the aggregate amount of principal and interest then due with respect to the Loans and Letter of Credit Liabilities held by it which is greater than the proportion received by any other Lender in respect of the aggregate amount of principal and interest then due with respect to the Loans and Letter of Credit Liabilities held by such other Lender, the Lender receiving such proportionately greater payment shall purchase such participations in the Loans and Letter of Credit Liabilities held by the other Lenders, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to the Loans and Letter of Credit Liabilities held by the Lenders shall be shared by the Lenders pro rata; provided that nothing in this Section shall impair the right of any Lender to exercise any right of set-off or counterclaim it may have and to apply the amount subject to such exercise to the payment of indebtedness of the Borrower other than its indebtedness hereunder.

SECTION 9.05. Amendments and Waivers. Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Borrower and the Required Lenders (and, if the rights or duties of any Issuing Bank or the Administrative Agent are affected thereby, by such Issuing Bank or the Administrative Agent, as applicable); provided that (subject to Section 2.19 with respect to any Defaulting Lender) no such amendment or waiver shall:

(a) unless signed by each affected Lender, (i) increase the Commitment of any Lender, (ii) reduce the principal of or interest on any Loan or the amount to be reimbursed in respect of any Letter of Credit or any interest thereon or any fees hereunder or (iii) postpone the date fixed for any payment of principal of or interest on any Loan or for reimbursement in respect of any Letter of Credit or any fees hereunder or for the termination of any Commitment or (except as expressly provided in Section 2.04) the expiry date of any Letter of Credit; or

(b) unless signed by all Lenders, (i) change the percentage of the Credit Exposures which shall be required for the Lenders or any of them to take any action under this Section or any other provision of this Agreement, (ii) change clause 9.05(a) or this clause 9.05(b) or (iii) change the pro rata distribution of payments to Lenders under this Agreement.

For avoidance of doubt, the operation of Section 2.17 or Section 2.18 in accordance with its terms is not an amendment subject to this Section 9.05.

SECTION 9.06. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section.

(b) Any Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that (i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender or an affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) subject to each such assignment (determined as of the date the Assignment and Assumption Agreement with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consent (each such consent not to be unreasonably withheld or delayed), (ii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement, (iii) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption Agreement, together with a processing and recordation fee of $3,500, (iv) the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire and (v) the assignee, if it shall not be a Lender, shall be required to execute and deliver the applicable forms to the extent required under Section 8.05(f) for any Lender, and no assignment shall be effective in connection herewith unless and until such forms are so delivered. Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits (and subject to the obligations) of Section 8.03, 8.05 and 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

(c) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in the State of Delaware or New York 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 amount (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 Administrative Agent and the Lenders shall 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 (as to its own interest hereunder), at any reasonable time and from time to time upon reasonable prior notice.

(d) Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (other than to the

Borrower or any of its affiliates) (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, Loans, Swingline Liabilities and/or Letter of Credit Liabilities owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in clause (i), (ii) or (iii) of Section 9.05(a) that affects such Participant. Subject to paragraph (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 8.03 and 8.05 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section (thereby becoming a Lender). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.04 as though it were a Lender, provided such Participant agrees to be subject to Section 9.04 as though it were a Lender. The Borrower shall be notified promptly by the applicable Lender of each participation sold by such Lender to a Participant pursuant to this paragraph.

(e) A Participant shall not be entitled to receive any greater payment under Section 8.03 or Section 8.05 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant shall not be entitled to the benefits of Section 8.05 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 8.05 (including Section 8.05(f) and 8.05(g)) and be subject to Section 8.06 as though it were a Lender.

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

(g) Each Lender that sells a participation shall, acting solely for this purpose as a nonfiduciary 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 this Agreement (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 rights and/or obligations under this Agreement (including all or a portion of its Commitment, Loans and/or Letter of Credit Liabilities or its other obligations under this Agreement) to any Person except to the extent that such disclosure is necessary to establish that such Commitment, Loans and/or Letter of Credit Liabilities or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the

Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

SECTION 9.07. Survival. All covenants, agreements, representations and warranties made by the Borrower herein shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, any Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or been terminated. The provisions of Sections 2.14, 8.03, 8.05 and 9.03 and Article 7 shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the termination of the Commitments.

SECTION 9.08. Governing Law; Submission to Jurisdiction. This Agreement shall be governed by and construed in accordance with the laws of the State of New York. Each party hereto hereby submits to the nonexclusive jurisdiction of the United States District Court for the Southern District of New York and of any New York State court sitting in New York County for purposes of all legal proceedings arising out of or relating to this Agreement or the transactions contemplated hereby. Each party hereto irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of the venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum.

SECTION 9.09. Counterparts; Integration. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement constitutes the entire agreement and understanding among the parties hereto and supersedes any and all prior agreements and understandings, oral or written, relating to the subject matter hereof.

SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

SECTION 9.11. USA Patriot Act. Each Lender hereby notifies the Borrower that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), 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 said Act.

SECTION 9.12. No Fiduciary Relationship. The Borrower, on behalf of itself and its affiliates, agrees that in connection with all aspects of the transactions contemplated hereby and any communications in connection therewith, the Borrower and its affiliates, on the one hand, and the Administrative Agent, the Lenders, the Issuing Banks and their affiliates, on the other hand, will have a business relationship that does not create, by implication or otherwise, any fiduciary duty on the part of the Administrative Agent, the Lenders, the Issuing Banks or their affiliates, and no such duty will be deemed to have arisen in connection with any such transactions or communications. The Administrative Agent, the Lenders, the Issuing Banks and their affiliates may be engaged, for their own accounts or the accounts of customers, in a broad range of transactions that involve interests that differ from those of the Borrower and its affiliates, and none of the Administrative Agent, the Lenders, the Issuing Banks or their affiliates has any obligation to disclose any of such interests to the Borrower or any of its affiliates. To the fullest extent permitted by law, the Borrower hereby waives and releases any claims that it or any of its affiliates may have against the Administrative Agent, the Lenders, the Issuing Banks and their affiliates with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby.

SECTION 9.13. Confidentiality. Each of the Administrative Agent, the Issuing Banks and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (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) upon the request or demand of any regulatory authority (including any self-regulatory authority) having jurisdiction over such Administrative Agent, Issuing Bank or Lender, as applicable, or its affiliates (in which case such Person shall, except with respect to any audit or examination conducted by bank accountants or any governmental bank regulatory authority exercising examination or regulatory authority (or any request by any governmental bank regulatory authority), (i) promptly notify the Borrower in advance of such disclosure, to the extent permitted by law, and (ii) so furnish only that portion of such information which the applicable Person is legally required to disclose), (c) to the extent required by any legal, judicial, administrative proceeding or other process or otherwise as required by applicable law or regulations (in which case such Administrative Agent, Issuing Bank or Lender, as applicable, shall (i) promptly notify the Borrower in advance of such disclosure, to the extent permitted by law, and (ii) so furnish only that portion of such information which the applicable Person is legally required to disclose), (d) to any other party to this Agreement, (e) to the CUSIP Service Bureau or any similar agency in connection with the issuance and monitoring of CUSIP numbers with respect to the Loans (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), (f) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (g) subject to an agreement containing provisions no less restrictive than those of this Section, to any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, (h) with the consent of the Borrower or (i) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, any Issuing Bank or any Lender on a nonconfidential basis from a source other than the Borrower or any of its Affiliates. For the

purposes of this Section, “Information” means all information received from the Borrower or any of its Subsidiaries relating to the Borrower or any of its Affiliates or their business, other than any such information that is available to the Administrative Agent, any Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Borrower or any of its Subsidiaries. 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 9.14. Non-Public Information. Each Lender acknowledges that all information, including requests for waivers and amendments, furnished by the Borrower or the Administrative Agent pursuant to or in connection with, or in the course of administering, this Agreement will be syndicate-level information, which may contain MNPI. Each Lender represents to the Borrower and the Administrative Agent that (i) it has developed compliance procedures regarding the use of MNPI and that it will handle MNPI in accordance with such procedures and applicable law, including Federal, state and foreign securities laws, and (ii) it has identified in its Administrative Questionnaire a credit contact who may receive information that may contain MNPI in accordance with its compliance procedures and applicable law, including Federal, state and foreign securities laws.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.

PRICING SCHEDULE

Each of “Commitment Fee Rate”, “Euro-Dollar Margin” and “Base Rate Margin” means, for any day, the rate per annum set forth in the table below (expressed in basis points per annum) in the column under such term and in the row corresponding to the Pricing Level applicable on such date:

	Applicable Ratings (Moody’s/S&P)	Commitment Fee	Euro-Dollar Margin	Base Rate Margin
Pricing Level 1	A2/A or higher	10.0	87.5	0.0
Pricing Level 2	A3/A-	12.5	112.5	12.5
Pricing Level 3	Baa1/BBB+	17.5	125.0	25.0
Pricing Level 4	Baa2/BBB	20.0	137.5	37.5
Pricing Level 5	Baa3/BBB- or lower	25.0	162.5	62.5

The applicable Pricing Level will be based on the Applicable Ratings (as defined below) from Moody’s and S&P. For purposes of the foregoing, (i) if either Moody’s or S&P shall not have in effect an Applicable Rating (other than by reason of the circumstances referred to in the next succeeding paragraph), then the applicable Pricing Level will be based on the single available Applicable Rating, (ii) if the Applicable Ratings established or deemed to have been established by Moody’s and S&P shall fall within different levels, the applicable Pricing Level shall be based on the higher of the two Applicable Ratings unless one of the two ratings is two or more levels lower than the other, in which case the applicable Pricing Level shall be determined by reference to the level one rating lower than the higher of the two Applicable Ratings, and (iii) if the Applicable Ratings established by Moody’s and S&P shall be changed (other than as a result of a change in the rating system of Moody’s or S&P), such change shall be effective as of the date on which it is first announced by the applicable rating agency, irrespective of when notice of such change shall have been furnished by the Borrower to the Administrative Agent and the Lenders. Each change in the applicable Pricing Level resulting from a change in the Applicable Ratings shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such change.

If the rating system of Moody’s or S&P shall change, or if either such rating agency shall cease to be in the business of rating corporate debt obligations, the Borrower and the Lenders shall negotiate in good faith to amend this definition to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Commitment Fee Rate, the Euro-Dollar Margin, and the Base Rate Margin shall be determined by reference to the rating most recently in effect from such rating agency prior to such change or cessation.

For any day when no Applicable Rating is in effect, the Commitment Fee Rate, the Euro-Dollar Margin, and the Base Rate Margin shall be the rates set forth opposite Pricing Level 5.

“Applicable Rating” shall mean, for each of Moody’s and S&P, (i) the rating assigned by such rating agency to the Borrower’s senior, unsecured long-term indebtedness for borrowed money that is not subject to any credit enhancement, or (ii) if such rating agency shall not have in effect a rating referred to in the preceding clause (i), then the rating assigned by such rating agency to the Loans, or (iii) if such rating agency shall not have in effect a rating referred to in either of the preceding clauses (i) or (ii), the “company” or “corporate credit” rating assigned by such rating agency to the Borrower.

The Lenders party to the Credit Agreement referred to below as of the date hereof

RE: Marathon Oil Corporation

Ladies and Gentlemen:

This opinion is being delivered pursuant to Section 3.01(b)(ii) of the Credit Agreement dated as of April 5, 2012 (the “Credit Agreement”) by and among Marathon Oil Corporation, a Delaware corporation (the “Borrower”), the Lenders party thereto as listed on the signature pages thereof, The Royal Bank of Scotland plc, as Syndication Agent, Citibank, N.A., Morgan Stanley Senior Funding, Inc. and UBS Securities LLC, as Documentation Agents, and JPMorgan Chase Bank, N.A., as Administrative Agent. Capitalized terms used herein that are not otherwise defined shall have the meanings ascribed to them in the Credit Agreement.

As Assistant General Counsel, Corporate & Finance, and Assistant Secretary of the Borrower, I have examined, or caused to be examined, originals or copies, certified or otherwise identified to my satisfaction, of each of the documents identified on Exhibit A attached hereto (each a “Loan Document”, and collectively, the “Loan Documents”) and such other documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as I have deemed necessary or advisable for purposes of this opinion.

Based upon the foregoing and subject to the assumptions, limitations and qualifications hereinafter stated, I am of the opinion that:

1. The Borrower is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and has all corporate powers and all material governmental licenses, authorizations, consents and approvals required to conduct its business as now conducted.

2. The execution, delivery and performance by the Borrower of the Loan Documents are (i) within the Borrower’s corporate powers, (ii) have been duly authorized by all necessary corporate action, (iii) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force and effect (except for any reports required to be filed by the Borrower with the SEC pursuant to the Exchange Act), (iv) do not violate in any material respect any law or regulation or any order of any Governmental Authority, in each case, applicable to or binding upon the Borrower, (v) do not contravene or constitute a default under any indenture, agreement or other instrument binding upon the Borrower, except to the extent that a Material Adverse Effect would not reasonably be expected to result therefrom, (vi) will not result in the creation or imposition of any Mortgage on any asset of the Borrower or any of its Subsidiaries and (vii) do not violate the certificate of incorporation or bylaws, as amended or restated to the date hereof, of the Borrower.

3. Except as set forth in the Borrower’s 2011 Form 10-K, there is no action, suit, arbitration or other proceeding, inquiry or investigation, at law or in equity, or before or by any court, public board or body, arbitrator or arbitral body, pending against the Borrower or of which the Borrower has otherwise received official notice or which to my knowledge is threatened against the Borrower, wherein there is a reasonable possibility of an unfavorable decision, ruling or finding that would reasonably be expected to result in a Material Adverse Effect.

The opinions set forth above are subject to the following additional assumptions, limitations and qualifications:

(A) In the examination of all agreements and other instruments and documents in connection with the opinions expressed herein, I have assumed, without independent investigation, except to the extent expressly provided in the opinions, (i) the due execution and delivery on behalf of the parties (other than the Borrower) thereto of the Loan Documents, (ii) the genuineness of all signatures (other than signatures of officers and agents of the Borrower), (iii) the authenticity of all documents submitted to me as originals and the conformity to authentic original documents of all copies submitted to me as certified, conformed or photostatic copies and (iv) that each Loan Document constitutes a valid, binding and enforceable obligation of each party thereto. In connection with the opinions expressed herein, I have relied upon the representations and warranties in the Loan Documents, certificates of officers and other representatives of the Borrower and certificates of public officials with respect to the accuracy of the factual matters contained therein or covered thereby.

(B) The opinions set forth above that are stated “to my knowledge” are based upon reasonable inquiries of an officer or representative of the Borrower, but are given without any other independent investigation.

(C) I have not been called upon to, and accordingly do not, express any opinion as to (i) the effect of any state or federal securities laws or regulations insofar as they are applicable to or otherwise affect any party to any Loan Document, the transactions contemplated by the Loan Documents, or the exercise of any rights or remedies of any party to the Loan Documents or (ii) various state and federal laws and regulations applicable to banks, insurance companies or other institutions that extend credit or the business or lending transactions of the Administrative Agent, the Lenders or any assignee or participant of any such Person which may relate to the Loan Documents or the transactions contemplated thereby.

I am a member of the State Bars of Texas and Ohio. The opinions set forth herein are based upon and limited to the laws of the State of Texas, the federal laws of the United States of America and the Delaware General Corporation Law (without consideration of any judicial or administrative interpretations of the Delaware General Corporation Law).

This opinion letter is furnished to you solely for your benefit in connection with the transactions consummated on the date hereof pursuant to the Loan Documents. This opinion letter and the opinions expressed herein may not be used for any other purpose or relied upon by any Person, and may not be furnished or quoted to any other Person, without, in each instance, my prior written consent.

The Lenders party to the Credit Agreement referred to below as of the date hereof

RE: Marathon Oil Corporation

Ladies and Gentlemen:

This opinion is being delivered to you pursuant to Section 3.01(b)(i) of the Credit Agreement dated as of April 5, 2012 (the “Credit Agreement”) by and among Marathon Oil Corporation, a Delaware corporation (the “Borrower”), the Lenders party thereto as listed on the signature pages thereof, The Royal Bank of Scotland plc, as Syndication Agent, Citibank, N.A., Morgan Stanley Senior Funding, Inc. and UBS Securities LLC, as Documentation Agents, and JPMorgan Chase Bank, N.A., as Administrative Agent. Capitalized terms used but not defined herein have the meanings given to them in the Credit Agreement.

We have acted as special counsel, in connection with the transactions provided for in the Credit Agreement, for the Borrower.

In connection with this opinion letter, we have examined executed counterparts of the documents identified on Exhibit A hereto (each a “Loan Document,” and collectively, the “Loan Documents”). In addition, we have examined certificates of representatives of the Borrower and other documents as the basis for our opinions hereinafter set forth.

On the basis of the foregoing, and subject to the assumptions, qualifications and limitations set forth below, we are of the opinion that each Loan Document constitutes the legal, valid and binding obligation of the Borrower, enforceable against the Borrower in accordance with its terms.

The foregoing opinion is subject to the following assumptions, qualifications and limitations:

JPMorgan Chase Bank, N.A.

April 5, 2012

A. In rendering our opinion, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, and the conformity to authentic original documents of all documents submitted to us as copies, which assumptions we have not independently verified. We have relied on certificates of officers of the Borrower with respect to the accuracy of the factual matters contained in those certificates. In addition, we have assumed that (i) the Loan Documents have been duly executed and delivered by each party thereto, (ii) the Loan Documents constitute valid, binding and enforceable obligations of each party thereto (other than the Borrower) and (iii) the laws of any jurisdiction other than the laws that are the subject of this opinion letter do not affect the terms of the Loan Documents.

B. Our opinion is subject to the effect of (i) applicable bankruptcy, insolvency, reorganization, arrangement, fraudulent transfer or conveyance, moratorium, conservatorship and similar laws affecting creditors’ rights and remedies generally, (ii) general principles of equity (whether considered in a proceeding in equity or at law) including, without limitation, the possible unavailability of specific performance, injunctive relief or any other equitable remedy, and (iii) principles of materiality and reasonableness and implied covenants of good faith and fair dealing.

C. We express no opinion with respect to the validity or enforceability of the following provisions to the extent that they are contained in the Loan Documents: (i) provisions regarding indemnities or exculpation from liability to the extent prohibited by federal or state laws and the public policies underlying those laws or that might require indemnification or contribution for, or exculpation from liability on account of, negligence, willful misconduct, unlawful acts, fraud or illegality of an indemnified or exculpated party; (ii) provisions purporting to waive, subordinate or not give effect to rights to notice, demands, legal defenses or other rights or benefits that cannot be waived or subordinated, or are rendered ineffective, under applicable law; (iii) provisions relating to powers of attorney, severability or any right of set-off that purports to be more extensive than the right of set-off available under applicable law; (iv) provisions relating to service of process or provisions restricting access to courts or purporting to affect the jurisdiction or venue of courts; (v) provisions providing that decisions by a party are conclusive or may be made in its sole discretion; (vi) provisions purporting to permit cumulative remedies to the extent not permitted under applicable law; or (vii) requirements that all amendments, waivers and terminations be in writing.

D. In rendering our opinion, we have assumed that (i) the Borrower is a corporation validly existing and in good standing under the laws of the State of

JPMorgan Chase Bank, N.A.

April 5, 2012

Delaware, (ii) the Borrower has the requisite corporate power and authority to execute and deliver the Loan Documents and to perform its obligations thereunder and (iii) the execution and delivery of each Loan Document by the Borrower and the performance by the Borrower of its obligations thereunder have been duly authorized by all requisite corporate action on the part of the Borrower.

This opinion letter is limited to the laws of the State of New York and the federal laws of the United States of America as in effect on the date hereof, and no opinion is expressed herein as to the laws of any other jurisdiction. This opinion letter is furnished to you solely for your benefit in connection with the transactions consummated on the date hereof pursuant to the Loan Documents. This opinion letter and the opinions expressed herein may not be used for any other purpose or relied upon by any Person, and may not be furnished or quoted to any other Person, without, in each instance, our prior written consent. At your request, we hereby consent to reliance hereon by any future Lender under the Credit Agreement that becomes a party thereto (a) pursuant to an assignment that is made and consented to in accordance with the express provisions of Section 9.06 of the Credit Agreement or (b) pursuant to an increase in the Commitments effected in accordance with Section 2.17 of the Credit Agreement, in each case on the condition and understanding that (i) this opinion letter speaks only as of the date hereof, (ii) we have no responsibility or obligation to update this opinion letter, to consider its applicability or correctness to other than its addressees, or to take into account changes in law, facts or any other developments of which we may later become aware, and (iii) any such reliance by any such Person that becomes a Lender must be actual and reasonable under the circumstances existing at the time of its becoming a Lender, including any changes in law, or any other developments known to or reasonably knowable by such Person at such time. This opinion letter speaks as of its date, and we undertake no (and hereby disclaim any) obligation or responsibility to update or supplement this opinion letter in response to subsequent changes in law or future events affecting any of the transactions contemplated by any Loan Document.
