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.


Applicable Rating Level	▇▇▇▇▇ ▇		▇▇▇▇▇ ▇		▇▇▇▇▇ ▇		▇▇▇▇▇ ▇		▇▇▇▇▇ 5		▇▇▇▇▇ ▇		▇▇▇▇▇ ▇

ratings falls in Applicable Rating Level 5, 6 or 7, then the lower of the two ratings shall be used to determine the Applicable Rating Level.

THE COMMITMENTS AND THE BORROWINGS

SECTION 2.1. The Commitments.

Subject to the terms and conditions set forth herein, each Lender severally agrees to make Advances to the Borrower in Dollars, at any time and from time to time prior to the Maturity Date, in an amount not to exceed at any time such Lender’s Commitment, provided, however, that the aggregate principal amount of Borrowings outstanding shall not exceed the aggregate Commitments and with respect to each individual Lender, the aggregate principal amount of Advances outstanding to such Lender shall not exceed such Lender’s Commitment Percentage of the aggregate Commitments. Unless and until the Borrower has obtained a Long-Term PSCW Approval (and provided the Agent and, via the Agent, each Lender with a copy thereof), amounts borrowed and repaid hereunder may not be reborrowed; thereafter, subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow Advances.

SECTION 2.2. Method of Borrowing.

By no later than 11:00 a.m. (i) on the date of the requested Borrowing that will comprise Base Rate Advances or (ii) three Business Days prior to the date of the requested Borrowing that will comprise Eurodollar Advances, the Borrower shall submit to the Agent a written Notice of Borrowing setting forth (A) the amount requested, (B) whether such Advances shall accrue interest at the Base Rate or the Eurodollar Rate, (C) with respect to Borrowings that will be comprised of Eurodollar Advances, the Interest Period applicable thereto, and (D) certification that the Borrower has complied in all respects with Section 5.2.

SECTION 2.3. Funding of Borrowings.

(a) Upon receipt of a Notice of Borrowing, the Agent shall promptly inform the Lenders as to the terms thereof. Each such Lender shall make its Commitment Percentage of the requested Borrowing available to the Agent by 1:00 p.m. on the date specified in the Notice of Borrowing by deposit, in Dollars, of immediately available funds at the principal offices of the Agent in New York, New York or at such other address as the Agent may designate in writing. The amount of the requested Borrowing will then be made available to the Borrower by the Agent by crediting the account of the Borrower on the books of such office of the Agent, to the extent the amount of such Borrowing is made available to the Agent.

(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.

SECTION 2.4. Continuations and Conversions.

The Borrower shall have the option, on any Business Day, to continue existing Eurodollar Advances for a subsequent Interest Period, to convert Base Rate Advances into Eurodollar Advances or to convert Eurodollar Advances into Base Rate Advances; provided, however, that (i) each such continuation or conversion must be requested by the Borrower

pursuant to a written Notice of Continuation/Conversion in compliance with the terms set forth below, (ii) except as provided in Section 4.1, Eurodollar Advances may be continued or converted into Base Rate Advances only on the last day of the Interest Period applicable hereto, (iii) Eurodollar Advances may not be continued nor may Base Rate Advances be converted into Eurodollar Advances during the existence and continuation of a Default or Event of Default and (iv) any request to extend a Eurodollar Advance that fails to comply with the terms hereof or any failure to request an extension of a Eurodollar Advance that fails to 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.

SECTION 2.5. Minimum Amounts.

Each request for a Borrowing or a conversion or continuation hereunder shall be subject to the following requirements: (i) each Borrowing consisting of Eurodollar Advances shall be in a minimum of $5,000,000 (and in integral multiples of $1,000,000 in excess thereof); (ii) each Borrowing consisting of Base Rate Advances shall be in a minimum amount of the lesser of $1,000,000 (and in integral multiples of $500,000 in excess thereof) and the remaining amount available to be borrowed; and (iii) no more than ten Eurodollar Borrowings shall be outstanding hereunder at any one time. 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 $10,000,000 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 Borrowings. Any reduction in (or termination of) the Commitments shall be permanent and may not be reinstated.

(b) Mandatory Reduction of Commitments.

(i) The Commitments shall automatically terminate on the Maturity Date.

(ii) 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.

Each Lender shall notify the Agent by Requisite Notice by the date specified by the Agent (which date shall be a Business Day and shall not be less than 15 Business Days prior to, nor more than 30 days prior to, the then Maturity Date) that either (A) such Lender declines to consent to extending the Maturity Date or (B) such Lender consents to extending the Maturity Date. Any Lender not responding within the above time period shall be deemed not to have consented to extending the Maturity Date. 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.

(b) If any Lender declines, or is deemed to have declined, to consent to such request for extension (a “Declining Lender”), provided that no Default or Event of Default has occurred and is continuing at such time, the Borrower may elect to either (i) request the non-Declining Lenders to extend the Maturity Date, or (ii) 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 4.3) and in its sole discretion, require such Declining 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 (A) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority and (B) the assigning Declining Lender shall have received 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 Declining Lender and all other amounts owed to such assigning Declining Lender hereunder, including amounts owed pursuant to Sections 4.1 through 4.4.

On or prior to the Maturity Extension Decision Date, the Borrower shall deliver to the Agent, in form and substance satisfactory to the Agent and the Lenders (1) the corporate resolution of the Borrower authorizing such extension, certified as in effect as of the Maturity Extension Decision Date and the related incumbency certificate of the

Borrower, and (2) new or amended promissory notes, if requested by any new or affected Lender, evidencing such new or revised Commitment. The Agent shall distribute an amended Schedule 1.1. to Credit Agreement (which shall thereafter be incorporated into this Agreement), to reflect any changes in Lenders, the Commitment and each Lender’s pro rata share thereof.

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 Advance 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 Advance 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 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 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 an amount equal to (A) an amount of interest calculated at the Eurodollar Rate that would have accrued on the amount in question, for the period from the date of such prepayment or of such failure to borrow, convert, continue or repay to the last day of the applicable Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate

of interest for such Eurodollar Advances provided for herein minus (B) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank Eurocurrency market. 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 issued pursuant to Section 3.10, 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 4.4 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.

Each Lender 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 Advances hereunder and enter into this Agreement. Each Lender 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 by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Lender 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. With respect to the Advances made and all obligations of the Borrower owing to the Agent, the Agent in its individual capacity shall have the same rights and powers under this Agreement as any Lender and may exercise the same as though they were not Agent, and the terms “Lender” and “Lenders” shall include JPMorgan Chase in its individual capacity.

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. If the Agent resigns under this Agreement, the Required Lenders 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.

SECTION 11.2. Right of Set-Off.

In addition to any rights now or hereafter granted under applicable law or otherwise, and not by way of limitation of any such rights, upon the occurrence of an Event of Default and the commencement of remedies described in Section 9.2, each Lender is authorized at any time and from time to time, without presentment, demand, protest or other notice of any kind (all of which rights being hereby expressly waived), to set off and to appropriate and apply any and all deposits (general or special) and any other indebtedness at any time held or owing by such Lender (including, without limitation branches, agencies or Affiliates of such Lender wherever located) to or for the credit or the account of the Borrower against obligations and liabilities of the Borrower to the Lenders hereunder or under the other Credit Documents or otherwise, irrespective of whether the Agent or the Lenders shall have made any demand hereunder and although such obligations, liabilities or claims, or any of them, may be contingent or unmatured,

and any such set-off shall be deemed to have been made immediately upon the occurrence of an Event of Default even though such charge is made or entered on the books of such Lender subsequent thereto. 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.

SECTION 11.3. Benefit of Agreement.

(a) Generally. This Credit Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto; provided the Borrower may not assign and transfer any of its interests without the prior written consent of the Lenders and the Agent; and provided, further, that the rights of each Lender to transfer, assign or grant participations in its rights and/or obligations hereunder shall be limited as set forth below in this Section 11.3.

(b) Assignments. Each Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Advances and its Commitment); provided, however, that:

(i) each such assignment shall be to an Eligible Assignee;

(iii) each such assignment by a Lender shall be of a constant and not varying, percentage of all of its rights and obligations under this Agreement; and

(iv) the parties to such assignment shall execute and deliver to the Agent for its acceptance an Assignment Agreement together with a processing fee (other than in connection with any assignment to a Lender, an Approved Fund of any Lender or an Affiliate of such Lender) from the assignor of $3,500.

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 Credit 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 evidencing Advances are issued to the assignor and the assignee.

(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 (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 Advance 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 Advance, (ii) if such SPC elects not to exercise such option or otherwise fails to provide all or any part of such Advance, the Granting Lender shall be obligated to make such Advance 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 Advance to the Borrower. The making of an Advance by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Advance 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 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 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 Advance 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 Advance to the Granting Lender and (ii) disclose on a confidential basis any information relating to its Advances 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 Advance 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 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 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 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 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 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 and each of the Lenders) and (B) any bankruptcy or insolvency proceeding of the Borrower; and (iii) indemnify the Agent 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 Advance 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.

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 Agent in addition to the Required Lenders and the Borrower, affect the rights or duties of the Agent 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 Advances, 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 Credit 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. Disclosure.

Notwithstanding anything herein to the contrary, the Agent and each Lender (and each officer, director, employee, agent and advisor of each such Person) may disclose to any and all other Persons, without limitation of any kind, the “tax treatment” and “tax structure” (in each case within the meaning of Treasury Regulation Section 1.6011-4) of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to such Person relating to such “tax treatment” and “tax structure”. For the avoidance of doubt, no disclosure to any Person is permitted to the extent such exposure does not relate to such “tax treatment” or “tax structure”. The foregoing is intended to comply with the presumption set forth in Treasury Regulation Section 1.6011-4(b)(3)(iii) and should be interpreted in a manner consistent with such regulation.

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 Advances and the repayment of the Borrowings and other obligations and the termination of the Commitments hereunder.

SECTION 11.13. Waiver of Jury Trial; Waiver of Consequential Damages.

EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR

COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS CREDIT AGREEMENT, ANY OF THE OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY. THE BORROWER AGREES NOT TO ASSERT ANY CLAIM AGAINST THE AGENT, ANY LENDER, ANY OF THEIR SUBSIDIARIES, AFFILIATES, OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, ATTORNEYS OR AGENTS, ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES ARISING OUT OF OR OTHERWISE RELATING TO ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN.
