shall increase by an amount equal to the Utilization Fee set forth below (the “Utilization Fee”) during any period (and for only such period) in which more than 50% of the Commitments are utilized. Upon the occurrence and during the continuance of any Event of Default, the Applicable Margin shall increase by 2.0% per annum, and if any Advance is a Eurodollar Advance, it will convert to a Base Rate Advance at the end of the Interest Period then in effect for such Eurodollar Advance.

(b) No Lender shall be responsible for the failure or delay by any other Lender in its obligation to make Advances hereunder; provided, however, that the failure of any Lender to fulfill its obligations hereunder shall not relieve any other Lender of its obligations hereunder. Unless the Agent shall have been notified by any Lender prior to the date of any such Borrowing (in the case of a Eurodollar Borrowing) or the time of any such Borrowing (in the case of a Base Rate Borrowing) that such Lender does not intend to make available to the Agent its portion of the Borrowing to be made on such date, the Agent may assume that such Lender has made such amount available to the Agent on the date of such Borrowing, and the Agent in reliance upon such assumption, may (in its sole discretion but without any obligation to do so) make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Agent, the Agent shall be able to recover such corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Agent’s demand therefor, the Agent will promptly notify the Borrower, and the Borrower shall immediately pay such corresponding amount to the Agent. The Agent shall also be entitled to recover from the Lender or the Borrower, as the case may be, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Agent to the Borrower to the date such corresponding amount is recovered by the Agent at a per annum rate equal to, (i) if from the Borrower, the applicable rate for such Advance pursuant to the Notice of Borrowing and (ii) if from a Lender, the Federal Funds Rate.

comply with the terms hereof or any failure to request an extension of a Eurodollar Advance at the end of an Interest Period shall constitute a conversion to a Base Rate Advance on the last day of the applicable Interest Period. Each continuation or conversion must be requested by the Borrower no later than 11:00 a.m. (A) on the date for a requested conversion of a Eurodollar Advance to a Base Rate Advance or (B) three Business Days prior to the date for a requested continuation of a Eurodollar Advance or conversion of a Base Rate Advance to a Eurodollar Advance, in each case pursuant to a written Notice of Continuation/Conversion submitted to the Agent, which shall set forth (1) whether the Borrower wishes to continue or convert such Advances and (2) if the request is to continue a Eurodollar Advance or convert a Base Rate Advance to a Eurodollar Advance, the Interest Period applicable thereto.

For the purposes of this Section, all Eurodollar Borrowings with the same Interest Periods that begin and end on the same date shall be considered as one Eurodollar Borrowing, but Eurodollar Borrowings with different Interest Periods, even if they begin on the same date, shall be considered separate Eurodollar Borrowings.

SECTION 2.6. Reduction of the Commitments.

(a) Optional Reduction of Commitments. Upon at least five Business Days’ notice, the Borrower shall have the right to permanently terminate or reduce the aggregate unused amount of the Commitments at any time or from time to time; provided that each partial reduction shall be in an aggregate amount at least equal to $5,000,000 and in integral multiples of $1,000,000 above such amount and no reduction shall be made that would reduce the Commitments to an amount less than the then Outstanding Credits. Any reduction in (or termination of) the Commitments shall be permanent and may not be reinstated.

(b) Mandatory Reduction of Commitments. For so long as the Borrower has not obtained a Long-Term PSCW Approval, upon the repayment or prepayment of any Borrowing pursuant to Section 3.2 or Section 3.3, the Commitments shall automatically and permanently be reduced by an amount equal to the aggregate principal amount of the Borrowing so repaid or prepaid.

The Agent shall, after receiving the notifications from all of the Lenders or the expiration of such period, whichever is earlier, notify the Borrower and the Lenders of the results thereof. The Borrower may request no more than two extensions pursuant to this Section.

Each Request for Issuance shall specify (i) the date (which shall be a Business Day) of issuance of such Letter of Credit (or the date of effectiveness of such extension, modification or amendment) and the stated expiry date thereof (which shall be no later than one year following the date of such issuance), (ii) the proposed stated amount of such Letter of Credit, (iii) the name and address of the beneficiary of such Letter of Credit and (iv) a statement of drawing conditions applicable to such Letter of Credit, and if such Request for Issuance relates to an amendment or modification of a Letter of Credit, it shall be accompanied by the consent of the beneficiary of the Letter of Credit thereto. Each Request for Issuance shall be irrevocable unless modified or rescinded by the Borrower not less than two Business Days prior to the proposed date of issuance (or effectiveness) specified therein. Not later than 12:00 noon (New York City time) on the proposed date of issuance (or effectiveness) specified in such Request for Issuance, and upon fulfillment of the applicable conditions precedent and the other requirements set forth herein, the Fronting Bank shall issue (or extend, amend or modify) such Letter of Credit and provide notice and a copy thereof to the Agent, which shall promptly furnish copies thereof to the Lenders. The Fronting Bank shall provide to the Agent, on a monthly basis, a list of the amounts and expiration dates of all undrawn Letters of Credit, a copy of which list the Agent shall furnish to each Lender that requests such list.

(b) No Letter of Credit shall be requested or issued hereunder if, after the issuance thereof, (i) the Outstanding Credits would exceed the aggregate Commitments or (ii) the LC Outstandings would exceed the LC Commitment Amount.

(c) In the event that any Letter of Credit remains outstanding beyond the fifteenth day prior to the Maturity Date, the Borrower shall either (i) pay to the Agent an amount equal to 103% of the LC Outstandings on the later of such date and the date of issuance of such Letter of Credit, which amount the Agent shall hold in the Cash Collateral Account for the account of the Borrower, without interest, for the purpose of paying any draft presented, with the excess, if any, to be returned to the Borrower upon termination or expiration of such Letter of Credit and payment in full of all amounts due hereunder or (ii) deliver a back-up letter of credit to the Agent securing the Borrower’s reimbursement obligations with respect to such Letter of Credit in form and substance acceptable to the Fronting Bank and the Agent and from a creditworthy financial institution acceptable to the Agent. While any Letter of Credit is outstanding, the Agent may not release funds held in the Cash Collateral Account pursuant to this subsection (c) without the consent of all Lenders.

(d) Each Lender, upon issuance of a Letter of Credit, shall be deemed to have purchased without recourse a participation from the Fronting Bank in such Letter of Credit and the rights and obligations arising thereunder and any collateral relating thereto, in each case in an amount equal to such Lender’s Commitment Percentage of the obligations under such Letter of Credit, and shall absolutely, unconditionally and irrevocably assume, as primary obligor and not as surety, and be obligated to pay to the Fronting Bank therefor and discharge when due, such Lender’s Commitment Percentage of the obligations arising under such Letter of Credit. Without limiting the scope and nature of each Lender’s participation in any Letter of Credit, to the extent that the Fronting Bank has not been reimbursed as required hereunder or under any such Letter of Credit, each Lender shall pay to the Fronting Bank its Commitment Percentage of such unreimbursed drawing in same day funds on the day of notification by the Fronting Bank of an unreimbursed drawing pursuant to the provisions of subsection (e). The obligation of each Lender so to reimburse the Fronting Bank shall be absolute and unconditional and shall not be affected by the occurrence of a Default, an Event of Default or any other occurrence or event. Any such reimbursement shall not relieve or otherwise impair the obligation of the Borrower to reimburse the Fronting Bank under any Letter of Credit, together with interest as hereinafter provided.

(e) In the event of any drawing under any Letter of Credit, the Fronting Bank will promptly notify the Borrower. Unless the Borrower shall immediately notify the Fronting Bank of its intent otherwise to reimburse the Fronting Bank for any drawing made prior to the Maturity Date, the Borrower shall be deemed to have requested a Base Rate Advance in the amount of such drawing as provided in subsection (f), the proceeds of which will be used to satisfy the reimbursement obligation of the Borrower with respect to such drawing. If, at any time on or after the Maturity Date, any drawing is made under any Letter of Credit, the Fronting Bank shall instruct the Agent to withdraw from the Cash Collateral Account funds in an amount equal to the amount of such drawing, which the Agent shall transfer to the Fronting Bank in order to reimburse the Fronting Bank for such drawing. In the case of any drawing made under any Letter of Credit prior to the Maturity Date, the Borrower shall reimburse the Fronting Bank on the day such drawing is paid either with the proceeds of an Advance obtained hereunder or otherwise in same day funds as provided herein. If the Borrower shall fail to reimburse the Fronting Bank as provided herein, the unreimbursed amount of such drawing shall bear interest at a per annum rate equal to the Base Rate plus two percent (2%) per annum. The Borrower’s reimbursement obligations hereunder shall be absolute and unconditional under all circumstances

irrespective of any rights of set-off, counterclaim or defense to payment that the applicable account party or the Borrower may claim or have against the Fronting Bank, the Lenders, the beneficiary of the Letter of Credit drawn upon or any other Person, including, without limitation, any defense based on any failure of the applicable account party or the Borrower to receive consideration or the legality, validity, regularity or unenforceability of the Letter of Credit. The Fronting Bank will promptly notify the Lenders of the amount of any unreimbursed drawing and each Lender shall promptly pay to the Fronting Bank, in immediately available funds, the amount of such Lender’s Commitment Percentage of such unreimbursed drawing. Such payment shall be made on the day such notice is received by such Lender from the Fronting Bank if such notice is received at or before 2:00 p.m., otherwise such payment shall be made at or before 12:00 noon on the Business Day next succeeding the day such notice is received. If such Lender does not pay such amount to the Fronting Bank in full upon such request, such Lender shall, on demand, pay to the Fronting Bank interest on the unpaid amount during the period from the date the Lender received the notice regarding the unreimbursed drawing until the Lender pays such amount to the Fronting Bank in full at a rate per annum equal to, if paid within two Business Days of the date of drawing, the Federal Funds Rate and thereafter at a rate equal to the Base Rate. Each Lender’s obligation to make such payment to the Fronting Bank, and the right of the Fronting Bank to receive the same, shall be absolute and unconditional, shall not be affected by any circumstance whatsoever and without regard to the termination of this Agreement or the Commitments, the existence of a Default or Event of Default or the acceleration of the obligations hereunder and shall be made without any offset, abatement, withholding or reduction whatsoever. Simultaneously with the making of each such payment by a Lender to the Fronting Bank, such Lender shall, automatically and without any further action on the part of the Fronting Bank or such Lender, acquire a participation in an amount equal to such payment (excluding the portion of such payment constituting interest owing to the Fronting Bank) in the related unreimbursed drawing portion of the LC Outstandings and in the interest thereon, and shall have a claim against the Borrower with respect thereto.

(f) On any day on which the Borrower shall have requested, or been deemed to have requested, a Borrowing to reimburse a drawing under a Letter of Credit, the Fronting Bank shall give notice to the Lenders that a Borrowing has been requested or deemed requested in connection with a drawing under a Letter of Credit, in which case an Advance comprised solely of Base Rate Advances (each such borrowing, a “Mandatory Borrowing”) shall be immediately made by all Lenders (without giving effect to any termination of the Commitments pursuant to Section 9.1) pro rata based on each Lender’s Commitment Percentage, and the proceeds thereof shall be paid directly to the Fronting Bank for application to the applicable LC Outstandings. Each Lender hereby irrevocably agrees to make such Base Rate Advances upon any such request or deemed request on account of each such Mandatory Borrowing in the amount and in the manner specified in the preceding sentence and on the same such date notwithstanding (i) the amount of Mandatory Borrowing may not comply with the minimum amount for Borrowings otherwise required hereunder, (ii) whether any conditions specified in Article III are then satisfied, (iii) whether a Default or Event of Default then exists, (iv) failure of any such request or deemed request for a Borrowing to be made by the time otherwise required hereunder, (v) the date of such Mandatory Borrowing, or (vi) any reduction in or any termination of the Commitments. Such funding of Borrowings shall be made on the day notice of such Mandatory Borrowing is received by each Lender from the Fronting Bank if such notice is received at or before 2:00 p.m., otherwise such payment shall be made at or before 12:00 noon on the Business

Day next succeeding the day such notice is received. In the event that any Mandatory Borrowing cannot for any reason be made on the date otherwise required above (including, without limitation, as a result of the commencement of a proceeding under any applicable bankruptcy law with respect to the Borrower), then each Lender hereby agrees that it shall forthwith fund (as of the date the Mandatory Borrowing would otherwise have occurred, but adjusted for any payments received from the Borrower on or after such date and prior to such purchase) its Commitment Percentage of the outstanding LC Outstandings; provided, further, that in the event any Lender shall fail to fund its Commitment Percentage on the day the Mandatory Borrowing would otherwise have occurred, then the amount of such Lender’s unfunded Commitment Percentage therein shall bear interest payable to the Fronting Bank upon demand, if paid within two Business Days of such date, at the Federal Funds Rate, and thereafter, at the Base Rate.

(g) The payment obligations of each Lender under subsection (d) and of the Borrower under this Agreement in respect of any payment under any Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances:

(i) any lack of validity or enforceability of any Credit Document or any other agreement or instrument relating thereto or to such Letter of Credit;

(ii) any amendment or waiver of, or any consent to departure from, the terms of any Credit Document or such Letter of Credit;

(iii) the existence of any claim, set-off, defense or other right that the Borrower may have at any time against any beneficiary, or any transferee, of such Letter of Credit (or any persons for whom any such beneficiary or any such transferee may be acting), the Fronting Bank, or any other person, whether in connection with any Credit Document, the transactions contemplated hereby or by such Letter of Credit, or any unrelated transaction;

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

(v) payment in good faith by the Fronting Bank under the Letter of Credit issued by the Fronting Bank against presentation of a draft or certificate that does not comply with the terms of such Letter of Credit; or

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

(h) The Borrower assumes all risks of the acts and omissions of any beneficiary or transferee of any Letter of Credit. Neither the Fronting Bank, the Lenders nor any of their respective officers, directors, employees, agents or Affiliates shall be liable or responsible for (i) the use that may be made of such Letter of Credit or any acts or omissions of any beneficiary or transferee thereof in connection therewith, (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged, (iii) payment by the Fronting Bank against

presentation of documents that do not comply with the terms of such Letter of Credit, including failure of any documents to bear any reference or adequate reference to such Letter of Credit, or (iv) any other circumstances whatsoever in making or failing to make payment under such Letter of Credit, except that, and notwithstanding subsection (f) and the foregoing clauses (i) through (iii), the Borrower and each Lender shall have the right to bring suit against the Fronting Bank, and the Fronting Bank shall be liable to the Borrower and any Lender, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower or such Lender that the Borrower or such Lender proves were caused by the Fronting Bank’s willful misconduct or gross negligence, including, in the case of the Borrower, the Fronting Bank’s willful failure to make timely payment under such Letter of Credit following the presentation to it by the beneficiary thereof of a draft and accompanying certificate(s) that strictly comply with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, the Fronting Bank may accept sight drafts and accompanying certificates presented under the Letter of Credit issued by the Fronting Bank that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and payment against such documents shall not constitute willful misconduct or gross negligence by the Fronting Bank. Notwithstanding the foregoing, no Lender shall be obligated to indemnify the Borrower for damages caused by the Fronting Bank’s willful misconduct or gross negligence.

ARTICLE III

SECTION 3.1. Interest.

(a) Interest Rate.

(i) All Base Rate Advances shall accrue interest at the Base Rate.

(ii) All Eurodollar Advances shall accrue interest at the Eurodollar Rate applicable to such Eurodollar Advance.

(b) Interest Payments. Interest on Advances shall be due and payable in arrears on each Interest Payment Date.

SECTION 3.2. Prepayments.

(a) Optional Prepayments. The Borrower shall have the right to prepay Advances in whole or in part from time to time without premium or penalty; provided, however, that (i) Eurodollar Advances may be prepaid only on two Business Days’ prior written notice to the Agent, and any prepayment of Eurodollar Advances will be subject to Section 4.3, and (ii) each partial prepayment of Advances shall be in the minimum principal amount of $1,000,000 and in increments of $1,000,000 in excess thereof; provided that if less than $1,000,000 would remain outstanding after such prepayment, such prepayment shall be in the amount of the entire outstanding principal amount of the Advances. Amounts prepaid hereunder shall be applied as the Borrower may elect; provided that if the Borrower fails to specify an optional prepayment then such prepayment shall be applied first to Base Rate Advances, and then to Eurodollar Advances in direct order of Interest Period maturities.

(b) Mandatory Prepayments. If at any time the Outstanding Credits exceed the aggregate Commitments, the Borrower shall immediately make a principal payment to the Agent and/or deposit funds in the Cash Collateral Account in respect of LC Outstandings pursuant to Section 9.2(d) for the ratable accounts of the Lenders as shall be necessary in order that the Outstanding Credits (after giving effect to such prepayment) minus the amount held in the Cash Collateral Account after giving effect to such cash collateralization will be less than or equal to the aggregate Commitments. Any payments made under this subsection (b) shall be subject to Section 4.3 and, in the case of principal payments, shall be applied first to Base Rate Advances, and then to Eurodollar Advances in direct order of Interest Period maturities.

SECTION 3.3. Payment in full at Maturity.

On the Maturity Date, the entire outstanding principal balance of all Advances, together with accrued but unpaid interest and all other sums owing under this Agreement, shall be due and payable in full; provided, however, that until the Borrower obtains a Long-Term PSCW Approval (and provides the Agent with a copy thereof), the outstanding principal balance of each Advance, together with accrued but unpaid interest thereon, shall be due and payable in full on the earlier of (i) the date that is 364 days following the date on which such Advance is made and (ii) the Maturity Date.

SECTION 3.4. Fees.

(a) Facility Fee. In consideration of the Commitments being made available by the Lenders hereunder, the Borrower agrees to pay to the Agent, for the pro rata benefit of each Lender, a facility fee at a rate per annum equal to the Facility Fee Percentage in effect from time to time commencing on the date hereof, on the Commitment from time to time of such Lender (regardless of usage), quarterly in arrears, on the last day of each March, June, September and December, on the Maturity Date, and (if applicable) on the date after the Maturity Date on which all Advances and other amounts payable by the Borrower hereunder are paid in full (without regard to any termination of the Commitments on the Maturity Date).

(b) LC Fee. The Borrower agrees to pay the Agent for the account of the Fronting Bank an issuance fee (an “Issuance Fee”) and such other charges as are separately agreed upon with the Fronting Bank, and agrees to pay to the Agent for the account of the Lenders a fee (the “LC Fee”) on the face amount of each Letter of Credit issued by the Fronting Bank calculated at a rate per annum at all times equal to the Applicable Margin in effect for Eurodollar Rate Advances, in each case computed on the basis of the actual number of days that each Letter of Credit is outstanding over a year of 360 days, payable quarterly in arrears on each March 31, June 30, September 30 and December 31, and on the date that such Letter of Credit expires or is drawn in full.

SECTION 3.5. Place and Manner of Payments.

All payments of principal, interest, fees, expenses and other amounts to be made by the Borrower under this Agreement shall be received without setoff, deduction or counterclaim not

later than 2:00 p.m. on the date when due in Dollars and in immediately available funds by the Agent at its offices in New York, New York. The Borrower shall, at the time it makes any payment under this Agreement, specify to the Agent the Outstanding Credits, fees or other amounts payable by the Borrower hereunder to which such payment is to be applied (and in the event that it fails to specify, or if such application would be inconsistent with the terms hereof, the Agent shall distribute such payment to the Lenders in such manner as it reasonably determines in its sole discretion).

SECTION 3.6. Pro Rata Treatment.

Except to the extent otherwise provided herein, all Borrowings, each payment or prepayment of principal of any Advance, each payment of interest on the Advances, each payment of facility fees, LC Fees, each reduction of the Commitments, and each conversion or continuation of any Advance, shall be allocated pro rata among the Lenders in accordance with the respective Commitment Percentages; provided that, if any Lender shall have failed to fund its applicable pro rata share of any Borrowing, then any amount to which such Lender would otherwise be entitled pursuant to this Section 3.6 shall instead be payable to the Agent until the share of such Borrowing not funded by such Lender has been repaid; and provided, further, that in the event any amount paid to any Lender pursuant to this Section 3.6 is rescinded or must otherwise be returned by the Agent, each Lender shall, upon the request of the Agent, repay to the Agent the amount so paid to such Lender, with interest for the period commencing on the date such payment is returned by the Agent until the date the Agent receives such repayment at a rate per annum equal to, during the period to but excluding the date two Business Days after such request, the Federal Funds Rate, and thereafter, the Base Rate plus two percent per annum.

SECTION 3.7. Computations of Interest and Fees.

(a) Except for Base Rate Advances bearing interest determined under clause (i) of the definition of Base Rate, on which interest shall be computed on the basis of a 365 or 366 day year, as the case may be, all computations of interest and fees hereunder shall be made on the basis of the actual number of days elapsed over a year of 360 days.

(b) It is the intent of the Lenders and the Borrower to conform to and contract in strict compliance with applicable usury law from time to time in effect. All agreements between the Lenders and the Borrower are hereby limited by the provisions of this subsection, which shall override and control all such agreements, whether now existing or hereafter arising and whether written or oral. In no way, nor in any event or contingency (including but not limited to prepayment or acceleration of the maturity of any obligation), shall the interest taken, reserved, contracted for, charged, or received under this Agreement or otherwise exceed the maximum nonusurious amount permissible under applicable law. If, from any possible construction of any of the Credit Documents or any other document, interest would otherwise be payable in excess of the maximum nonusurious amount, any such construction shall be subject to the provisions of this subsection and such documents shall be automatically reduced to the maximum nonusurious amount permitted under applicable law, without the necessity of execution of any amendment or new document. If any Lender shall ever receive anything of value that is characterized as interest on the Advances under applicable law and that would, apart from this provision, be in excess of the maximum lawful amount, an amount equal to the amount that would have been

excessive interest shall, without penalty, be applied to the reduction of the principal amount owing on the Advances and not to the payment of interest, or refunded to the Borrower or the other payor thereof if and to the extent such amount that would have been excessive exceeds such unpaid principal amount of the Advances. The right to demand payment of the Advances or any other indebtedness evidenced by any of the Credit Documents does not include the right to receive any interest that has not otherwise accrued on the date of such demand, and the Lenders do not intend to charge or receive any unearned interest in the event of such demand. All interest paid or agreed to be paid to the Lenders with respect to the Advances shall, to the extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full stated term (including any renewal or extension) of the Advances so that the amount of interest on account of such indebtedness does not exceed the maximum nonusurious amount permitted by applicable law.

SECTION 3.8. Sharing of Payments.

Each Lender agrees that, in the event that any Lender shall obtain payment in respect of any Extension of Credit or any other obligation owing to such Lender under this Agreement through the exercise of a right of set-off, banker’s lien, counterclaim or otherwise (including, but not limited to, pursuant to the Bankruptcy Code) in excess of its pro rata share as provided for in this Agreement, such Lender shall promptly purchase from the other Lenders a participation in such Extension of Credit and other obligations, in such amounts and with such other adjustments from time to time, as shall be equitable in order that all Lenders share such payment in accordance with their respective ratable shares as provided for in this Agreement. Each Lender further agrees that if a payment to a Lender (which is obtained by such Lender through the exercise of a right of set-off, banker’s lien, counterclaim or otherwise) shall be rescinded or must otherwise be restored, each Lender that shall have shared the benefit of such payment shall, by repurchase of a participation theretofore sold, return its share of that benefit to each Lender whose payment shall have been rescinded or otherwise restored. The Borrower agrees that any Lender so purchasing such a participation may, to the fullest extent permitted by law, exercise all rights of payment, including set-off, banker’s lien or counterclaim, with respect to such participation as fully as if such Lender were a holder of such Advance or other obligation in the amount of such participation. Except as otherwise expressly provided in this Agreement, if any Lender shall fail to remit to the Agent or any other Lender an amount payable by such Lender to the Agent or such other Lender pursuant to this Agreement on the date when such amount is due, such payments shall accrue interest thereon, for each day from the date such amount is due until the day such amount is paid to the Agent or such other Lender, at a rate per annum equal to the Federal Funds Rate. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a setoff to which this Section 3.8 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders under this Section 3.8 to share in the benefits of any recovery on such secured claim.

SECTION 3.9. Additional Interest on Advances.

The Borrower agrees to pay to each Lender, so long as such Lender shall be required under regulations of the Board of Governors of the Federal Reserve System to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional

interest on the unpaid principal amount of each Eurodollar Advance of such Lender, from the date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance. Such additional interest shall be determined by such Lender and notified to the Borrower through the Agent, and such determination shall be conclusive and binding for all purposes, absent manifest error.

SECTION 3.10. Evidence of Debt.

(a) Each Lender shall maintain an account or accounts evidencing each Advance made by such Lender to the Borrower from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement. Each Lender will make reasonable efforts to maintain the accuracy of its account or accounts and to promptly update its account or accounts from time to time, as necessary.

(b) The Agent shall maintain the Register pursuant to Section 11.3(c), and a subaccount for each Lender, in which Register and subaccounts (taken together) shall be recorded (i) the amount, type and Interest Period of each such Advance hereunder, (ii) the amount of any principal or interest due and payable or to become due and payable to each Lender hereunder and (iii) the amount of any sum received by the Agent hereunder from or for the account of the Borrower and each Lender’s share thereof. The Agent will make reasonable efforts to maintain the accuracy of the subaccounts referred to in the preceding sentence and to promptly update such subaccounts from time to time, as necessary.

(c) The entries made in the accounts, Register and subaccounts maintained pursuant to subsection (b) (and, if consistent with the entries of the Agent, subsection (a)) shall be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of any Lender or the Agent to maintain any such account, such Register or such subaccount, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrower to repay the Advances made by such Lender in accordance with the terms hereof.

(d) Any Lender may request that its Advances be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note, in a form acceptable to the Agent, payable to the order of such Lender. Thereafter, the Advances evidenced by such promissory note and interest thereon shall at all times (including after any assignment pursuant to Section 11.3) be represented by one or more promissory notes payable to the order of the payee named therein or any assignee pursuant to Section 11.3, except to the extent that any such Lender or assignee subsequently returns any such promissory note for cancellation and requests that such Advances once again be evidenced as described in subsections (a) and (b) above.

ARTICLE IV

ADDITIONAL PROVISIONS REGARDING ADVANCES

SECTION 4.1. Eurodollar Borrowing Provisions.

(a) Unavailability. In the event that the Agent shall have determined in good faith (i) that Dollar deposits in the principal amounts requested with respect to a Eurodollar Borrowing are not generally available in the London interbank Eurodollar market or (ii) that reasonable means do not exist for ascertaining the Eurodollar Rate, the Agent shall, as soon as practicable thereafter, give notice of such determination to the Borrower and the Lenders. In the event of any such determination under clause (i) or (ii) above, until the Agent shall have advised the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (A) any request by the Borrower for Eurodollar Borrowings shall be deemed to be a request for Base Rate Borrowings, (B) any request by the Borrower for conversion into or continuation of Eurodollar Borrowings shall be deemed to be a request for conversion into or continuation of Base Rate Borrowings and (C) any Borrowings that were to be converted or continued as Eurodollar Borrowings on the first day of an Interest Period shall be converted to or continued as Base Rate Borrowings.

(b) Change in Legality. Notwithstanding any other provision herein, if any change, after the date hereof, in any law or regulation (including the introduction of any new law or regulation) or in the interpretation thereof by any Governmental Authority charged with the administration or interpretation thereof shall make it unlawful for any Lender to make or maintain any Eurodollar Advance or to give effect to its obligations as contemplated hereby with respect to any Eurodollar Advance, then, by written notice to the Borrower and to the Agent, such Lender may:

(i) declare that Eurodollar Advances, and conversions to or continuations of Eurodollar Advances, will not thereafter be made by such Lender hereunder, whereupon any request by the Borrower for, or for conversion into or continuation of, Eurodollar Borrowings shall, as to such Lender only, be deemed a request for, or for conversion into or continuation of, Base Rate Borrowings, unless such declaration shall be subsequently withdrawn; and

(ii) require that all outstanding Eurodollar Advances made by it be converted to Base Rate Advances in which event all such Eurodollar Advances shall be automatically converted to Base Rate Advances.

In the event any Lender shall exercise its rights under clause (i) or (ii) above, all payments and prepayments of principal that would otherwise have been applied to repay the Eurodollar Advances that would have been made by such Lender or the converted Eurodollar Advances of such Lender shall instead be applied to repay the Base Rate Advances made by such Lenders in lieu of, or resulting from the conversion of, such Eurodollar Advances.

(c) Requirements of Law. If at any time a Lender shall incur increased costs or reductions in the amounts received or receivable hereunder with respect to the making, the commitment to make or the maintaining of any Eurodollar Advance because of (i) any change,

after the date hereof, in any applicable law, governmental rule, regulation, guideline or order (or in the interpretation or administration thereof and including the introduction of any new law or governmental rule, regulation, guideline or such order) including, without limitation, the imposition, modification or deemed applicability of any reserves, deposits or similar requirements (such as, for example, but not limited to, a change in official reserve requirements, but, in all events, excluding reserves required under Regulation D to the extent included in the computation of additional interest under Section 3.9) or (ii) other circumstances affecting the London interbank Eurodollar market, then the Borrower shall pay to such Lender promptly upon written demand therefor, such additional amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as such Lender may determine in its sole discretion) as may be required to compensate such Lender for such increased costs or reductions in amounts receivable hereunder.

Each determination and calculation made by a Lender under this Section 4.1 shall, absent manifest error, be binding and conclusive on the parties hereto. Any conversions of Eurodollar Advances made pursuant to this Section 4.1 shall subject the Borrower to the payments required by Section 4.3. This Section shall survive termination of this Agreement and the other Credit Documents and payment of the Advances and all other amounts payable hereunder.

SECTION 4.2. Capital Adequacy.

If any Lender has determined that the adoption or effectiveness, after the date hereof, of any applicable law, rule or regulation regarding capital adequacy, or any change therein (after the date hereof), or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by such Lender (or its parent corporation) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Lender’s (or parent corporation’s) capital or assets as a consequence of its commitments or obligations hereunder to a level below that which such Lender (or its parent corporation) could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration such Lender’s (or parent corporation’s) policies with respect to capital adequacy), then, upon notice from such Lender, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction. Each determination by any such Lender of amounts owing under this Section 4.2 shall, absent manifest error, be conclusive and binding on the parties hereto. This Section shall survive termination of this Agreement and the other Credit Documents and payment of the Advances and all other amounts payable hereunder.

SECTION 4.3. Compensation.

The Borrower promises to indemnify each Lender and to hold each Lender harmless from any loss or expense that such Lender may sustain or incur as a consequence of (i) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Advances after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (ii) default by the Borrower in making any prepayment of a Eurodollar Advance after the Borrower has given a notice thereof in accordance with the provisions of this

Agreement, (iii) the making of a prepayment of Eurodollar Advances on a day that is not the last day of an Interest Period with respect thereto and (iv) the payment, continuation or conversion of a Eurodollar Advance on a day that is not the last day of the Interest Period applicable thereto or the failure to repay a Eurodollar Advance when required by the terms of this Agreement. Such indemnification may include such additional amount or amounts as will compensate such Lender for such loss or expense actually sustained or incurred by such Lender. The agreements in this Section shall survive the termination of this Agreement and the payment of the Advances and all other amounts payable hereunder.

SECTION 4.4. Taxes.

(a) Except as provided below in this Section 4.4, all payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any court or governmental body, agency or other official, excluding taxes measured by or imposed upon the net income of any Lender or its applicable lending office, or any branch or affiliate thereof, and all franchise taxes, branch taxes, taxes on doing business or taxes on the capital or net worth of any Lender or its applicable lending office, or any branch or affiliate thereof, in each case imposed in lieu of net income taxes (i) by the jurisdiction under the laws of which such Lender, applicable lending office, branch or affiliate is organized or is located, or in which its principal executive office is located, or any nation within which such jurisdiction is located or any political subdivision thereof or (ii) by reason of any connection between the jurisdiction imposing such tax and such Lender, applicable lending office, branch or affiliate other than a connection arising solely from such Lender having executed, delivered or performed its obligations, or received payment under or enforced, this Agreement. If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) are required to be withheld from any amounts payable to an Agent or any Lender hereunder, (A) the amounts so payable to the Agent or such Lender shall be increased to the extent necessary to yield to the Agent or such Lender (after payment of all Non-Excluded Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement and any promissory notes, provided, however, that the Borrower shall be entitled to deduct and withhold any Non-Excluded Taxes and shall not be required to increase any such amounts payable to any Lender that is not organized under the laws of the United States of America or a state thereof if such Lender fails to comply with the requirements of subsection (b) whenever any Non-Excluded Taxes are payable by the Borrower, and (B) as promptly as possible after requested, the Borrower shall send to the Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails to remit to the Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Agent and any Lender for any incremental Non-Excluded Taxes, interest or penalties that may become payable by the Agent or any Lender as a result of any such failure. The agreements in this Section shall survive the termination of this Agreement and the payment of the Borrowings and all other amounts payable hereunder.

(b) Each Lender that is not incorporated under the laws of the United States of America or a state thereof shall:

(i) (A) on or before the date of any payment by the Borrower under this Agreement to such Lender, deliver to the Borrower and the Agent (x) two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI, or successor applicable form, as the case may be, certifying that it is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes and (y) an Internal Revenue Service Form W-8 or W-9, or successor applicable form, as the case may be, certifying that it is entitled to an exemption from United States backup withholding tax; (B) deliver to the Borrower and the Agent two further copies of any such form or certification on or before the date that any such form or certification expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower; and (C) obtain such extensions of time for filing and complete such forms or certifications as may reasonably be requested by the Borrower or the Agent; or

(ii) in the case of any such Lender that is not a “bank” within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, (A) represent to the Borrower (for the benefit of the Borrower and the Agent) that it is not a bank within the meaning of Section 88l(c)(3)(A) of the Internal Revenue Code, (B) agree to furnish to the Borrower, on or before the date of any payment by the Borrower, with a copy to the Agent, two accurate and complete original signed copies of Internal Revenue Service Form W-8, or successor applicable form certifying to such Lender’s legal entitlement at the date of such certificate to an exemption from U.S. withholding tax under the provisions of Section 881(c) of the Internal Revenue Code with respect to payments to be made under this Agreement (and to deliver to the Borrower and the Agent two further copies of such form on or before the date it expires or becomes obsolete and after the occurrence of any event requiring a change in the most recently provided form and, if necessary, obtain any extensions of time reasonably requested by the Borrower or the Agent for filing and completing such forms), and (C) agree, to the extent legally entitled to do so, upon reasonable request by the Borrower, to provide to the Borrower (for the benefit of the Borrower and the Agent) such other forms as may be reasonably required in order to establish the legal entitlement of such Lender to an exemption from withholding with respect to payments under this Agreement.

Notwithstanding the above, if any change in treaty, law or regulation has occurred after the date such Person becomes a Lender hereunder which renders all such forms inapplicable or that would prevent such Lender from duly completing and delivering any such form with respect to it and such Lender so advises the Borrower and the Agent, then such Lender shall be exempt from such requirements. Each Person that shall become a Lender or a participant of a Lender pursuant to Section 11.3 shall, upon the effectiveness of the related transfer, be required to provide all of the forms, certifications and statements required pursuant to this subsection (b); provided that in the case of a participant of a Lender, the obligations of such participant of a Lender pursuant to this subsection (b) shall be determined as if the participant of a Lender were a Lender except that such participant of a Lender shall furnish all such required forms, certifications and statements to the Lender from which the related participation shall have been purchased.

SECTION 4.5. Replacement of Lenders.

The Agent and each Lender shall use reasonable efforts to avoid or mitigate any increased cost or suspension of the availability of an interest rate under Sections 4.1 through 4.4 above to the greatest extent practicable (including transferring the Advances to another lending office of Affiliate of a Lender) unless, in the opinion of the Agent or such Lender, such efforts would be likely to have an adverse effect upon it. In the event a Lender makes a request to the Borrower for additional payments in accordance with Section 4.1, 4.2 or 4.4, then, provided that no Default or Event of Default has occurred and is continuing at such time, the Borrower may, at its own expense (such expense to include any transfer fee payable to the Agent under Section 11.3(b) and any expense pursuant to Section 4) and in its sole discretion, require such Lender to transfer and assign in whole (but not in part), without recourse (in accordance with and subject to the terms and conditions of Section 11.3(b)), all of its interests, rights and obligations under this Agreement to an Eligible Assignee, which shall assume such assigned obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority and (ii) the Borrower or such assignee shall have paid to the assigning Lender in immediately available funds the principal of and interest accrued to the date of such payment on the portion of the Advances hereunder held by such assigning Lender and all other amounts owed to such assigning Lender hereunder, including amounts owed pursuant to Sections 4.1 through 4.4.

SECTION 9.2. Acceleration; Remedies.

Upon the occurrence of an Event of Default, and at any time thereafter unless and until such Event of Default has been waived by the Required Lenders (or the Lenders as may be required hereunder) the Agent may, and shall, upon the request and direction of the Required Lenders, by written notice to the Borrower take any of the following actions without prejudice to the rights of the Agent or any Lender to enforce its claims against the Borrower, except as otherwise specifically provided for herein:

(a) Termination of the Commitments. Declare the Commitments terminated whereupon the Commitments shall be immediately terminated.

(b) Acceleration of Advances. Declare the unpaid amount of all Advances and all other amounts payable by the Borrower hereunder to be due whereupon the same shall be immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower.

(c) Enforcement of Rights. Enforce any and all rights and interests created and existing under the Credit Documents, including, without limitation, all rights of set-off.

(d) Cash Collateralization of LC Outstandings. Notwithstanding anything to the contrary contained herein, no notice given or declaration made by the Agent pursuant to this Article IX shall affect (i) the obligation of the Fronting Bank to make any payment under any Letter of Credit in accordance with the terms of such Letter of Credit or (ii) the obligations of each Lender in respect of each such Letter of Credit; provided, however, that if an Event of Default has occurred and is continuing, the Agent shall at the request, or may with the consent, of the Required Lenders, upon notice to the Borrower, require the Borrower to deposit with the Agent an amount in the cash collateral account (the “Cash Collateral Account”) described below equal to the LC Outstandings on such date. Such Cash Collateral Account shall at all times be free and clear of all rights or claims of third parties. The Cash Collateral Account shall be maintained with the Agent in the name of, and under the sole dominion and control of, the Agent, and amounts deposited in the Cash Collateral Account shall bear interest at a rate equal to the rate generally offered by the Agent for deposits equal to the amount deposited by the Borrower in the Cash Collateral Account, for a term to be determined by the Agent, in its sole discretion. The Borrower hereby grants to the Agent for the benefit of the Fronting Bank and the Lenders a Lien in and hereby assigns to the Agent for the benefit of the Fronting Bank and the Lenders all of its right, title and interest in, the Cash Collateral Account and all funds from time to time on deposit therein to secure its reimbursement obligations in respect of Letters of Credit. If any drawings then outstanding or thereafter made are not reimbursed in full immediately upon demand or, in the case of subsequent drawings, upon being made, then, in any such event, the Agent may apply the amounts then on deposit in the Cash Collateral Account, toward the payment in full of any of the obligations as and when such obligations shall become due and payable. Upon payment in full, after the termination of the Letters of Credit, of all such obligations, the Agent will repay and reassign to the Borrower any cash then in the Cash Collateral Account and the Lien of the Agent on the Cash Collateral Account and the funds therein shall automatically terminate. In addition, at any time the Borrower is required under Section 2.8(c) or 3.2(b) to cash collateralize any of the LC Outstandings, the Borrower shall deposit such amount in the Cash Collateral Account. If, at any time no Event of Default has occurred and is continuing and the cash on deposit in the Cash Collateral Account shall exceed the LC Outstandings, then the Agent will repay and reassign to the Borrower cash in an amount equal to such excess, and the Lien of the Agent on such cash shall automatically terminate.

(e) Notwithstanding the foregoing, if an Event of Default specified in Section 9.1(e) shall occur, then the Commitments shall automatically terminate and all Advances, all accrued interest in respect thereof, all accrued and unpaid fees and other indebtedness or obligations owing to the Lenders and the Agent hereunder shall immediately become due and payable without the giving of any notice or other action by the Agent or the Lenders.

(f) Notwithstanding the fact that enforcement powers reside primarily with the Agent, each Lender has, to the extent permitted by law, a separate right of payment and shall be considered a separate “creditor” holding a separate “claim” within the meaning of Section 101(5) of the Bankruptcy Code or any other insolvency statute.

SECTION 9.3. Allocation of Payments After Event of Default.

Notwithstanding any other provisions of this Agreement, after the occurrence of an Event of Default, all amounts collected or received by the Agent or any Lender on account of amounts outstanding under any of the Credit Documents shall be paid over or delivered as follows:

FIRST, to the payment of all reasonable out-of-pocket costs and expenses (including without limitation reasonable attorneys’ fees) of the Agent or any of the Lenders in connection with enforcing the rights of the Lenders under the Credit Documents, pro rata as set forth below;

SECOND, to payment of any fees owed to the Agent or any Lender, pro rata as set forth below;

THIRD, to the payment of all accrued interest payable to the Lenders hereunder, pro rata as set forth below;

FOURTH, to the payment or cash collateralization, as applicable, of the Outstanding Credits, pro rata as set forth below;

FIFTH, to all other obligations that shall have become due and payable under the Credit Documents and not repaid pursuant to clauses “FIRST” through “THIRD” above; and

SIXTH, to the payment of the surplus, if any, to whoever may be lawfully entitled to receive such surplus.

In carrying out the foregoing, (i) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category; and (ii) each of the Lenders shall receive an amount equal to its pro rata share (based on the proportion that the then Outstanding Credits held by such Lender bears to the aggregate then outstanding Advances of amounts available to be applied.

The Agent may deem and treat the Lenders as the owner of its interests hereunder for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Agent in accordance with Section 11.3(b). The Agent shall be fully justified in failing or refusing to take any action under this Agreement or under any of the other Credit Documents unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder or under any of the other Credit Documents in accordance with a request of the Required Lenders (or to the extent specifically provided in Section 11.6, all the Lenders) and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders (including their successors and assigns).

SECTION 10.5. Notice of Default.

The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Agent has received notice from a Lender or the Borrower referring to the Credit Document, describing such Default or Event of Default and stating that such notice is a “notice of default”.

The Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders.

SECTION 10.6. Non-Reliance on Agent and Other Lenders.

Each Lender and the Fronting Bank expressly acknowledges that neither the Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates has made any representations or warranties to it and that no act by the Agent or any affiliate thereof hereinafter taken, including any review of the affairs of the Borrower, shall be deemed to constitute any representation or warranty by the Agent to any Lender or the Fronting Bank. Each Lender and the Fronting Bank represents to the Agent that it has, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the Borrower and made its own decision to make its Extensions of Credit hereunder and enter into this Agreement. Each Lender and the Fronting Bank also represents that it will, independently and without reliance upon the 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 analysis, appraisals and decisions in taking or not taking action under this Agreement, and to make such investigation as it deems necessary to inform itself as to the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the Borrower. Except for notices, reports and other documents expressly required to be furnished to the Lenders and the Fronting Bank by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Lender or the Fronting Bank with any credit or other information concerning the business, operations,

assets, property, financial or other conditions, prospects or creditworthiness of the Borrower that may come into the possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

SECTION 10.7. Indemnification.

Each Lender agrees to indemnify the Agent in its capacity as such (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so), ratably according to its Commitment Percentage, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (including without limitation at any time following the payment in full of the Advances and the other obligations of the Borrower hereunder) be imposed on, incurred by or asserted against the Agent in its capacity as such in any way relating to or arising out of this Agreement or the other Credit Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of the Agent. If any indemnity furnished to the Agent for any purpose shall, in the opinion of the Agent, be insufficient or become impaired, the Agent may call for additional indemnity and cease, or not commence, to do the acts indemnified against until such additional indemnity is furnished. The agreements in this Section 10.7 shall survive the payment of the Advances and all other amounts payable hereunder.

SECTION 10.8. Agent in Its Individual Capacity.

The Agent in its individual capacity and its Affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrower as though the Agent were not Agent hereunder.

SECTION 10.9. Successor Agent.

The Agent may, and at the request of the Required Lenders shall, resign as the Agent upon 30 days notice to the Lenders and the Fronting Bank. If the Agent resigns under this Agreement, the Required Lenders and the Fronting Bank shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall be approved by the Borrower so long as no Event of Default has occurred and is continuing. If no successor agent is appointed prior to the effective date of the resignation of the Agent, the Agent may appoint, after consulting with the Lenders and the Borrower, a successor agent from among the Lenders. Upon the acceptance of its appointment as successor agent hereunder, such successor agent shall succeed to all the rights, powers and duties of the retiring Agent, and the term “Agent” shall mean such successor agent and the retiring Agent’s appointment, powers and duties as Agent shall be terminated. After any retiring Agent’s resignation hereunder as Agent, the provisions of this

Section 10 and Section 11.5 shall inure to its benefit as to any actions taken or omitted to be taken, by it while it was the Agent under this Agreement. If no successor agent has accepted appointment as the Agent by the date that is 30 days following a retiring Agent’s notice of resignation, the retiring Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above.

The Borrower hereby agrees that any Person purchasing a participation in the Advances and the Commitments hereunder pursuant to Section 11.3(c) may exercise all rights of set-off with respect to its participation interest as fully as if such Person were a Lender hereunder.

Upon execution, delivery, and acceptance of such Assignment Agreement, the assignee thereunder shall be a party hereto and, to the extent of such assignment, have the obligations, rights, and benefits of a Lender hereunder and the assigning Lender shall, to the extent of such assignment, relinquish its rights and be released from its obligations under this Agreement. Upon the consummation of any assignment pursuant to this subsection (b), the assignor, the Agent and the Borrower shall make appropriate arrangements so that, if required, new promissory notes are issued to the assignor and the assignee.

observance by the Borrower of any of its obligations under this Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto; (C) such assignee represents and warrants that it is legally authorized to enter into such Assignment Agreement; (D) such assignee confirms that it has received a copy of this Agreement, the other Credit Documents and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment Agreement; (E) such assignee will independently and without reliance upon the Agent, such assigning Lender or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Credit Documents; (F) such assignee appoints and authorizes the Agent to take such action on its behalf and to exercise such powers under this Agreement or any other Credit Document as are delegated to the Agent by the terms hereof or thereof, together with such powers as are reasonably incidental thereto; and (G) such assignee agrees that it will perform in accordance with their terms all the obligations that by the terms of this Agreement and the other Credit Documents are required to be performed by it as a Lender.

(c) Register. The Agent shall maintain a copy of each Assignment Agreement delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Advances owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) Acceptance. Upon its receipt of an Assignment Agreement executed by the parties thereto, together with and payment of the processing fee, the Agent shall, if such Assignment Agreement has been completed and is in substantially the form of Exhibit D hereto, (i) accept such Assignment Agreement, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the parties thereto.

(e) Participations. Each Lender may sell participations to one or more Persons in all or a portion of its rights, obligations or rights and obligations under the Credit Documents (including all or a portion of its Commitment and its Advances); provided, however, 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, (iii) the participant shall be entitled to the benefit of the yield protection provisions contained in Sections 4.1 through 4.4, inclusive, and the right of set-off contained in Section 11.2, and (iv) the Borrower shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement, and such Lender shall retain the sole right to enforce the obligations of the Borrower relating to its Advances and to approve any amendment, modification, or waiver of any provision of this Agreement (other than amendments, modifications, or waivers decreasing the amount of principal of or the rate at which interest is payable on such Advances, extending any principal payment date or date fixed for the payment of interest on such Advances, or extending its Commitment).

(f) Nonrestricted Assignments. Notwithstanding any other provision set forth in this Agreement:

(i) any Lender may at any time, without the consent of the Borrower or the Agent, assign all or any portion of its rights under the Credit Documents to any Federal Reserve Bank as security. No such assignment shall release the assigning Lender from its obligations hereunder;

(ii) any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”) of such Granting Lender identified as such in writing from time to time by the Granting Lender to the Agent and the Borrower, the option to provide to the Borrower all or any part of any Extension of Credit that such Granting Lender would otherwise be obligated to make to such Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any such SPC to make any Extension of Credit, (ii) if such SPC elects not to exercise such option or otherwise fails to provide all or any part of such Extension of Credit, the Granting Lender shall be obligated to make such Extension of Credit pursuant to the terms hereof and (iii) no SPC or Granting Lender shall be entitled to receive any greater amount pursuant to Section 4.1(c) or 4.4 than the Granting Lender would have been entitled to receive had the Granting Lender not otherwise granted such SPC the option to provide any Extension of Credit to the Borrower. The making of an Extension of Credit by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Extension of Credit were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would otherwise be liable so long as, and to the extent that, the related Granting Lender provides such indemnity or makes such payment. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against or join any other person in instituting against such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. Notwithstanding the foregoing, the Granting Lender unconditionally agrees to indemnify the Borrower, the Agent, the Fronting Bank and each Lender against all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be incurred by or asserted against the Borrower, the Agent, the Fronting Bank or such Lender, as the case may be, in any way relating to or arising as a consequence of any such forbearance or delay in the initiation of any such proceeding against its SPC. Each party hereto hereby acknowledges and agrees that no SPC shall have the rights of a Lender hereunder, such rights being retained by the applicable Granting Lender. Accordingly, and without limiting the foregoing, each party hereby further acknowledges and agrees that no SPC shall have any voting rights hereunder and that the voting rights attributable to any Extension of Credit made by an SPC shall be exercised only by the relevant Granting Lender and that each Granting Lender shall serve as the administrative agent and attorney-in-fact for its SPC and shall on behalf of its SPC receive any and all payments made for the benefit of such SPC and take all actions hereunder to the extent, if any, such

SPC shall have any rights hereunder. In addition, notwithstanding anything to the contrary contained in this Agreement, any SPC may (i) with notice to, but without the prior written consent of any other party hereto, assign all or a portion of its interest in any Extension of Credit to the Granting Lender and (ii) disclose on a confidential basis any information relating to its Extensions of Credit to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This Section may not be amended without the prior written consent of each Granting Lender, all or any part of whose Extension of Credit is being funded by an SPC at the time of such amendment; and

(iii) any Lender at any time may assign all or any portion of its rights and obligations under this Agreement to any Affiliate or Approved Fund of such Lender, provided such assignment does not result in the incurrence of any increased payment obligations by any Borrower under Section 4.2 or 4.4. Upon execution, delivery, and acceptance of such Assignment Agreement, the assignee thereunder shall be a party hereto and, to the extent of such assignment, have the obligations, rights, and benefits of a Lender hereunder and the assigning Lender shall, to the extent of such assignment, relinquish its rights and be released from its obligations under this Agreement. If the assignee is not incorporated under the laws of the United States of America or a state thereof, it shall deliver to the Borrower and the Agent certification as to exemption from deduction or withholding of taxes in accordance with Section 4.4.

(g) Information. Any Lender may furnish any information concerning the Borrower in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants) or to any party that such Lender has engaged or proposes to engage in any swap, securitization or derivative transaction involving any of such Lender’s rights or obligations hereunder.

SECTION 11.4. No Waiver; Remedies Cumulative.

No failure or delay on the part of the Agent, the Fronting Bank or any Lender in exercising any right, power or privilege hereunder or under any other Credit Document and no course of dealing between the Borrower and the Agent, the Fronting Bank or any Lender shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Credit Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights and remedies provided herein are cumulative and not exclusive of any rights or remedies that the Agent, the Fronting Bank or any Lender would otherwise have. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Agent, the Fronting Bank or the Lenders to any other or further action in any circumstances without notice or demand.

SECTION 11.5. Payment of Expenses, etc.

The Borrower agrees to: (i) pay all reasonable out-of-pocket costs and expenses of the Agent in connection with (A) the negotiation, preparation, execution and delivery and

administration of this Agreement and the other Credit Documents and the documents and instruments referred to therein (including, without limitation, legal fees of the Agent) and (B) any amendment, waiver or consent relating hereto and thereto including, but not limited to, any such amendments, waivers or consents resulting from or related to any work-out, renegotiation or restructure relating to the performance by the Borrower under this Agreement; (ii) pay all reasonable out-of-pocket costs and expenses of the Agent, the Fronting Bank and the Lenders in connection with (A) enforcement of the Credit Documents and the documents and instruments referred to therein (including, without limitation, in connection with any such enforcement, the reasonable fees and disbursements of counsel for the Agent, the Fronting Bank and each of the Lenders) and (B) any bankruptcy or insolvency proceeding of the Borrower; and (iii) indemnify the Agent, the Fronting Bank and each Lender, its affiliates, officers, directors, employees, advisors and agents from and hold each of them harmless against any and all losses, liabilities, claims, damages or expenses incurred by any of them as a result of, or arising out of, or in any way related to, or by reason of, any investigation, litigation or other proceeding (whether or not the Agent or any Lender is a party thereto) related to the entering into and/or performance of any Credit Document or the use of proceeds of any Extension of Credit hereunder or the consummation of any other transactions contemplated in any Credit Document, including, without limitation, the reasonable fees and disbursements of counsel incurred in connection with any such investigation, litigation or other proceeding (but excluding any such losses, liabilities, claims, damages or expenses to the extent incurred by reason of gross negligence or willful misconduct on the part of the Person to be indemnified). Such expenses shall be reimbursed by the Borrower upon presentation of a statement of account, which statement shall be conclusive absent manifest error.

SECTION 11.6. Amendments, Waivers and Consents.

Neither this Agreement, nor any other Credit Document nor any of the terms hereof or thereof may be amended, changed, waived, discharged or terminated unless such amendment, change, waiver, discharge or termination is in writing and signed by the Required Lenders and the Borrower; provided that no amendment, waiver or consent shall, unless in writing and signed by the Fronting Bank in addition to the Required Lenders and the Borrower, affect the rights or duties of the Fronting Bank under this Agreement or any other Credit Document, and provided further, that no such amendment, change, waiver, discharge or termination shall without the consent of each Lender affected thereby:

(a) extend the Maturity Date, or postpone or extend the time for any payment or prepayment of principal, except as provided in Section 2.7;

(b) reduce the rate or extend the time of payment of interest (other than as a result of waiving the applicability of any post-default increase in interest rates) thereon or fees or other amounts payable hereunder;

(d) increase or extend the Commitment (it being understood and agreed that a waiver of any Default or Event of Default shall not constitute a change in the terms of any Commitment of any Lender);

(e) release the Borrower from its obligations under the Credit Documents;

(f) amend, modify or waive any provision of this Section 11.6 or Section 3.6, 3.8, 4.1, 4.2, 4.3, 4.4, 9.1(a), 11.2, 11.3 or 11.5;

(g) reduce any percentage specified in, or otherwise modify, the definition of Required Lenders; or

(h) consent to the assignment or transfer by the Borrower of any of its rights and obligations under (or in respect of) the Credit Documents.

Notwithstanding the foregoing, this Agreement may be amended and restated without the consent of any Lender or the Agent if, upon giving effect to such amendment and restatement, such Lender or the Agent, as the case may be, shall no longer be a party to this Agreement (as so amended and restated) or have any Commitment or other obligation hereunder and shall have been paid in full all amounts payable hereunder to such Lender or the Agent, as the case may be. No provision of Section 10 may be amended or modified without the consent of the Agent.

Notwithstanding the fact that the consent of all the Lenders is required in certain circumstances as set forth above, each Lender is entitled to vote as such Lender sees fit on any reorganization plan that affects the Extensions of Credit, and each Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy Code supersedes the unanimous consent provisions set forth herein.

SECTION 11.7. Counterparts/Telecopy.

This Agreement may be executed in any number of counterparts, each of which where so executed and delivered shall be an original, but all of which shall constitute one and the same instrument. Delivery of executed counterparts by telecopy shall be as effective as an original and shall constitute a representation that an original will be delivered.

SECTION 11.8. Headings.

The headings of the Sections and subsections hereof are provided for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

SECTION 11.9. Defaulting Lender.

Each Lender understands and agrees that if such Lender is a Defaulting Lender then it shall not be entitled to vote on any matter requiring the consent of the Required Lenders or to object to any matter requiring the consent of all the Lenders; provided, however, that all other benefits and obligations under the Credit Documents shall apply to such Defaulting Lender.

SECTION 11.10. Confidentiality.

Each of the Agent, each Lender and the Fronting Bank agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed by such Person (i) to its Affiliates and to its and its Affiliates’ respective partners, directors,

officers, employees, agents, advisors and other representatives (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), (ii) to the extent requested by any regulatory authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (iii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iv) to any other party hereto, (v) in connection with the exercise of any remedies hereunder or under any other Credit Document or any action or proceeding relating to this Agreement or any other Credit Document or the enforcement of rights hereunder or thereunder, (vi) subject to an agreement containing provisions substantially the same as those of this Section, to (A) any assignee of or participant, or any prospective assignee of or participant in, any of its rights or obligations under this Agreement or (B) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (vii) with the consent of the Borrower or (viii) to the extent such Information (A) becomes publicly available other than as a result of a breach of this Section or (B) becomes available to the Agent, any Lender, the Fronting Bank or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower. Notwithstanding anything in this Agreement to the contrary, the Borrower, the Agent, the Fronting Bank and each Lender (and each officer, director, employee, agent and advisor of each such Person) shall not be limited from disclosing the US tax treatment or the US tax structure of the transactions contemplated hereby. For 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 Subsidiaries or any of their respective businesses, other than any such information that is available to the Agent, any Lender or the Fronting Bank on a nonconfidential basis prior to disclosure by the Borrower or any of its Subsidiaries, provided that, in the case of information received from the Borrower or any of its Subsidiaries after the date hereof, such information is clearly identified at the time of delivery as confidential. 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 11.11. Survival of Indemnification and Representations and Warranties.

All indemnities set forth herein and all representations and warranties made herein shall survive the execution and delivery of this Agreement, the making of Extensions of Credit and the repayment of the Borrowings and other obligations and the termination of the Commitments hereunder.
