ARTICLE II

THE CREDITS

• SECTION 2.01. Commitments.

(a) Subject to the terms and conditions and relying upon the representations and warranties herein set forth, each Lender and each Fronting Bank (as applicable) agrees, severally and not jointly, as follows: (i) each Lender agrees to make Loans to the Borrower at any time and from time to time until the Commitment Termination Date up to the amount of such Lender’s Available Commitment, (ii) each Fronting Bank agrees to issue Letters of Credit for the account of the Borrower at any time and from time to time until the fifth Business Day preceding the Commitment Termination Date in an aggregate stated amount at any time outstanding not to exceed such Fronting Bank’s LC Fronting Bank Commitment, and (iii) each Lender agrees to purchase participations in such Letters of Credit as more fully set forth in Section 2.17.

16

Notwithstanding the foregoing, at no time shall (A) the aggregate amount of Outstanding Credits exceed the aggregate amount of the Lenders’ Commitments, (B) any Lender’s Outstanding Credits exceed the amount of such Lender’s Commitment and (C) any Fronting Bank make any Extension of Credit relating to a Letter of Credit if such Extension of Credit would cause (x) the aggregate amount of Outstanding Credits to exceed the aggregate amount of the Lenders’ Commitments or (y) the aggregate LC Outstandings relating to such Fronting Bank to exceed such Fronting Bank’s LC Fronting Bank Commitment.

(b) Within the foregoing limits, the Borrower may borrow, pay or prepay Loans and request new Extensions of Credit on and after the date hereof and prior to the Commitment Termination Date subject to the terms, conditions and limitations set forth herein.

SECTION 2.02. Loans.

(a) Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with their respective Commitments; provided, however , that the failure of any Lender to make any Loan shall not in itself relieve any other Lender of its obligation to lend hereunder (it being understood, however, that no Lender shall be responsible for the failure of any other Lender to make any Loan required to be made by such other Lender). The Loans comprising any Borrowing shall be in an aggregate principal amount that is an integral multiple of $5,000,000 and not less than $25,000,000 (or an aggregate principal amount equal to the remaining balance of the Available Commitments).

(b) Each Borrowing shall be comprised entirely of Eurodollar Loans or ABR Loans, as the Borrower may request pursuant to Section 2.03. Each Lender may at its option make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement. Borrowings of more than one Type may be outstanding at the same time.

(c) Subject to subsection (d) below, each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds to the Agent in New York, New York, not later than noon, New York City time, and the Agent shall by 2:00 p.m., New York City time, credit the amounts so received to the account or accounts specified from time to time in one or more notices delivered by the Borrower to the Agent or, if a Borrowing shall not occur on such date because any condition precedent herein specified shall not have been met, return the amounts so received to the respective Lenders. Loans shall be made by the Lenders pro rata in accordance with Section 2.12. Unless the Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make available to the Agent such Lender’s portion of such Borrowing, the Agent may assume that such Lender has made such portion available to the Agent on the date of such Borrowing in accordance with this subsection (c) and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have made such portion available to the Agent, such Lender and the Borrower (without waiving any claim against such Lender for such Lender’s failure to make such portion available) severally agree to repay to the Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the

17

Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to the Loans comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Effective Rate. If such Lender shall repay to the Agent such corresponding amount, such amount shall constitute such Lender’s Loan as part of such Borrowing for purposes of this Agreement.

(d) The Borrower may refinance all or any part of any Borrowing with a Borrowing of the same or a different Type, subject to the conditions and limitations set forth in this Agreement. Any Borrowing or part thereof so refinanced shall be deemed to be repaid or prepaid in accordance with Section 2.05 or 2.09, as applicable, with the proceeds of a new Borrowing, and the proceeds of the new Borrowing, to the extent they do not exceed the principal amount of the Borrowing being refinanced, shall not be paid by the Lenders to the Agent or by the Agent to the Borrower pursuant to subsection (c) above.

• SECTION 2.03. Borrowing Procedure.

In order to request a Borrowing, the Borrower shall hand deliver or send via facsimile to the Agent a duly completed Borrowing Request (i) in the case of a Eurodollar Borrowing, not later than 11:00 a.m., New York City time, three Business Days before such Borrowing, and (ii) in the case of an ABR Borrowing, not later than 11:00 a.m., New York City time, one Business Day before such Borrowing. Such notice shall be irrevocable and shall in each case specify (A) whether the Borrowing then being requested is to be a Eurodollar Borrowing or an ABR Borrowing, (B) the date of such Borrowing (which shall be a Business Day) and the amount thereof, (C) if such Borrowing is to be a Eurodollar Borrowing, the Interest Period with respect thereto, which shall not end after the Commitment Termination Date, and (D) the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of this Agreement. If no election as to the Type of Borrowing is specified in any such notice, then the requested Borrowing shall be deemed an ABR Borrowing. If no Interest Period with respect to any Eurodollar Borrowing is specified in any such notice, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration (subject to the limitations set forth in the definition of "Interest Period"). If the Borrower shall not have given notice in accordance with this Section of its election to refinance a Borrowing prior to the end of the Interest Period in effect for such Borrowing, then the Borrower shall (unless such Borrowing is repaid at the end of such Interest Period) be deemed to have given notice of an election to refinance such Borrowing with an ABR Borrowing. Notwithstanding any other provision of this Agreement to the contrary, no Borrowing shall be requested if the Interest Period with respect thereto would end after the Commitment Termination Date. The Agent shall promptly advise the Lenders of any notice given pursuant to this Section and of each Lender’s portion of the requested Borrowing.

• SECTION 2.04. Fees.

(a) The Borrower agrees to pay to each Lender, through the Agent, on each March 31, June 30, September 30 and December 31 (with the first payment being due on March 31, 2007) and on each date on which the Commitment of such Lender shall be terminated or reduced as provided herein, a commitment fee (a " Commitment Fee "), at a rate per annum equal to the Commitment Fee Percentage on the unused portion of the Commitment of such Lender during the preceding quarter (or other period commencing on the date of this Agreement or ending on the Commitment Termination Date or any date on which the Commitment of such Lender shall be terminated).

18

(b) All Commitment Fees shall be computed on the basis of the actual number of days elapsed in a year of 360 days. The Commitment Fee due to each Lender shall commence to accrue on the date of this Agreement, and shall cease to accrue on the date of termination of the Commitment of such Lender as provided herein.

(c) The Borrower agrees to pay the Agent the fees from time to time payable to it in its capacity as Agent pursuant to the Letter Agreement (the " Administrative Fees ").

(d) The Borrower agrees to pay the Agent, for the account of the Fronting Bank that issued any Letter of Credit, a fronting fee equal to 0.125% of the stated amount of such Letter of Credit (a "Fronting Fee") and such other charges with respect to such Letter of Credit as are agreed upon with such Fronting Bank and as are customary. The Borrower 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 any Fronting Bank, calculated at a rate per annum equal to the Applicable Margin for Eurodollar Loans (regardless of whether any such Loans are then outstanding). All Fronting Fees and LC Fees shall be computed on the basis of the actual number of days that each such Letter of Credit is outstanding, assuming a year of 360 days, payable 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.

(e) The Borrower agrees to pay to each Lender, through the Agent, on the date of the initial Extension of Credit, a fee equal to .55% of the Commitment of such Lender as of the date hereof (the " Drawdown Fee ").

(f) All Fees shall be paid on the dates due, in immediately available funds, to the Agent for distribution, if and as appropriate, among the Lenders. Once paid, none of the Fees shall be refundable under any circumstances.

• SECTION 2.05. Repayment of Loans; Evidence of Indebtedness.

(a) The outstanding principal balance of each (i) Eurodollar Loan shall be due and payable on the last day of the Interest Period applicable thereto and on the Commitment Termination Date and (ii) ABR Loan shall be due and payable on the Commitment Termination Date.

(b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness to such Lender resulting from each Extension of Credit made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement.

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

19

(d) The entries made in the accounts maintained pursuant to subsections (b) and (c) above shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations therein recorded; provided, however , that the failure of any Lender or the Agent to maintain such accounts or any error therein shall not in any manner affect the obligations of the Borrower to repay the Outstanding Credits in accordance with their terms.

• SECTION 2.06. Interest on Loans.

(a) The Loans comprising each Eurodollar Borrowing shall bear interest (computed on the basis of the actual number of days elapsed over a year of 360 days) at a rate per annum equal to the LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin from time to time in effect for Eurodollar Borrowings.

(b) The Loans comprising each ABR Borrowing shall bear interest (computed on the basis of the actual number of days elapsed over a year of (i) 365 or 366 days, as the case may be, for periods during which the Alternate Base Rate is determined by reference to the Prime Rate and (ii) 360 days for other periods) at a rate per annum equal to the Alternate Base Rate plus the Applicable Margin from time to time in effect for ABR Borrowings.

(c) Interest on each Loan shall be payable on each Interest Payment Date applicable to such Loan except as otherwise provided in this Agreement. The applicable LIBO Rate or Alternate Base Rate for each Interest Period or day within an Interest Period, as the case may be, shall be determined by CS, and such determination shall be conclusive absent manifest error; provided that CS shall, upon request, provide to the Borrower a certificate setting forth in reasonable detail the basis for such determination.

• SECTION 2.07. Alternate Rate of Interest.

In the event, and on each occasion, that on the day two Business Days prior to the commencement of any Interest Period for a Eurodollar Borrowing the Agent shall have determined (i) that dollar deposits in the principal amounts of the Eurodollar Loans comprising such Borrowing are not generally available in the London interbank market or (ii) that reasonable means do not exist for ascertaining the LIBO Rate, the Agent shall, as soon as practicable thereafter, give facsimile 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, any request by the Borrower for a Eurodollar Borrowing pursuant to Section 2.03 shall be deemed to be a request for an ABR Borrowing. In the event the Required Lenders notify the Agent that the rates at which dollar deposits are being offered will not adequately and fairly reflect the cost to such Lenders of making or maintaining Eurodollar Loans during such Interest Period, the Agent shall notify the Borrower of such notice and until the Required Lenders shall have advised the Agent that the circumstances giving rise to such notice no longer exist, any request by the Borrower for a Eurodollar Borrowing shall be deemed a request for an ABR

20

Borrowing. Each determination by the Agent hereunder shall be made in good faith and shall be conclusive absent manifest error; provided that the Agent, shall, upon request, provide to the Borrower a certificate setting forth in reasonable detail the basis for such determination.

• SECTION 2.08. Termination and Reduction of Commitments.

(a) The Commitments shall terminate automatically on the Commitment Termination Date.

(b) Upon at least two Business Days’ prior irrevocable written notice to the Agent, the Borrower may, without premium or penalty, at any time in whole permanently terminate, or from time to time in part permanently reduce, the Commitments; provided, however, that (i) each partial reduction of the Commitments shall be in an integral multiple of $10,000,000 and in a minimum principal amount of $10,000,000 and (ii) no such termination or reduction shall be made that would reduce the Commitments to an amount less than (1) the aggregate amount of Outstanding Credits on the date of such termination or reduction (after giving effect to any prepayment made pursuant to Section 2.09) or (2) $50,000,000, unless the result of such termination or reduction referred to in this clause (2) is to reduce the Commitments to $0. The Agent shall advise the Lenders of any notice given pursuant to this subsection (b) and of each Lender’s portion of any such termination or reduction of the Commitments.

(c) The Commitments shall, on each date on which the Borrower prepays or redeems all or any portion of the Incremental Notes, automatically and permanently reduce by a principal amount that is the same percentage of the Total Commitment on the date hereof as the principal amount of the Incremental Notes prepaid or redeemed on such date is of the original principal amount of Incremental Notes, determined on a cumulative basis, until the Total Commitment has been reduced to $500,000,000.

(d) Upon any reduction of the "Commitments" (as such term is defined in the Existing Facility), the Total Commitment shall automatically and permanently reduce by an amount that is the same percentage of the Total Commitment as of the date hereof that the amount of such reduction of the "Commitments" under the Existing Facility is of the aggregate amount of the "Commitments" under the Existing Facility as of the date hereof.

(e) Each reduction in the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments. The Borrower shall pay to the Agent for the account of the Lenders, on the date of each termination or reduction of the Commitments, the Commitment Fee on the amount of the Commitments so terminated or reduced, in each case accrued through the date of such termination or reduction.

• SECTION 2.09. Prepayment.

(a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing, in whole or in part, upon giving a written notice substantially in the form of Exhibit C (a " Prepayment Notice ") via facsimile (or telephone notice promptly confirmed by facsimile) to the Agent: (i) before 11:00 a.m., New York City time, three Business Days prior to prepayment, in the case of Eurodollar Loans, and (ii) before 11:00 a.m., New York City time, one Business Day prior to prepayment, in the case of ABR Loans; provided, however , that each

21

partial prepayment shall be in an amount which is an integral multiple of $10,000,000 and not less than $10,000,000. Each Prepayment Notice shall specify the prepayment date and the principal amount of each Borrowing (or portion thereof) to be prepaid, shall be irrevocable and shall commit the Borrower to prepay such Borrowing (or portion thereof) by the amount stated therein on the date stated therein. All prepayments under this Section shall be subject to Section 8.05 but otherwise without premium or penalty. All prepayments under this Section shall be accompanied by accrued interest on the principal amount being prepaid to the date of payment.

(b) On any date on which the Total Commitment shall be reduced pursuant to Section 2.08(c) or (d) above, the Borrower shall, with respect to outstanding Loans, prepay such Loans and/or, with respect to LC Outstandings, deliver cash collateral to be held by the Agent in the Cash Collateral Account to the extent and for the duration necessary to cause the Outstanding Credits minus the amount of cash held in the Cash Collateral Account to be no greater than the Total Commitment (after giving effect to any such reduction pursuant to Section 2.08(d) of (d)). At such time that cash is no longer required to be held by the Agent as collateral under this Section 2.09(b), the Agent will repay and reassign to the Borrower any such cash then on deposit in the Cash Collateral Account, and the Lien of the Agent on the Cash Collateral Account with respect to such cash shall automatically terminate.

• SECTION 2.10. Reserve Requirements; Change in Circumstances.

(a) Notwithstanding any other provision herein, if after the date of this Agreement any change in applicable law or regulation or in the interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof (whether or not having the force of law) shall change the basis of taxation of payments to any Lender or any Fronting Bank hereunder (except for changes in respect of taxes on the overall net income of such Lender or such Fronting Bank (as the case may be) or its lending office imposed by the jurisdiction in which such Lender’s or such Fronting Bank’s (as the case may be) principal executive office or lending office is located), or shall result in the imposition, modification or applicability of any reserve, special deposit or similar requirement against assets of, deposits with or for the account of or credit extended by any Lender or such Fronting Bank (as the case may be) or shall result in the imposition on any Lender, any Fronting Bank or the London interbank market of any other condition affecting this Agreement, such Lender’s Commitment or any Extension of Credit (other than an ABR Loan) made by such Lender or such Fronting Bank, and the result of any of the foregoing shall be to increase the cost to such Lender or such Fronting Bank (as the case may be) of making or maintaining any Outstanding Credit (other than an ABR Loan) or to reduce the amount of any sum received or receivable by such Lender or such Fronting Bank (as the case may be) hereunder (whether of principal, interest or otherwise) by an amount deemed by such Lender or such Fronting Bank (as the case may be) to be material, then the Borrower shall, upon receipt of the notice and certificate provided for in subsection (c) below promptly pay to such Lender or such Fronting Bank (as the case may be) such additional amount or amounts as will compensate such Lender or such Fronting Bank (as the case may be) for such additional costs incurred or reduction suffered.

(b) If any Lender or Fronting Bank shall have determined that the adoption of any law, rule, regulation or guideline arising out of the July 1988 report of the Basle Committee on

22

Banking Regulations and Supervisory Practices entitled "International Convergence of Capital Measurement and Capital Standards," or the adoption after the date hereof of any other law, rule, regulation or guideline regarding capital adequacy, or any change in any of the foregoing or in the interpretation or administration of any of the foregoing by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender or Fronting Bank (or any lending office of such Lender or such Fronting Bank) or any Lender’s or any Fronting Bank’s holding company 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 such Fronting Bank’s (as the case may be) capital or on the capital of such Lender’s or such Fronting Bank’s (as the case may be) holding company, if any, as a consequence of this Agreement, such Lender’s Commitment or the Extensions of Credit made by such Lender or such Fronting Bank (as the case may be) pursuant hereto to a level below that which such Lender or such Fronting Bank (as the case may be) or such Lender’s or such Fronting Bank’s (as the case may be) holding company could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such Fronting Bank’s (as the case may be) policies and the policies of such Lender’s or such Fronting Bank’s (as the case may be) holding company with respect to capital adequacy) by an amount deemed by such Lender or such Fronting Bank (as the case may be) to be material, then from time to time such additional amount or amounts as will compensate such Lender or such Fronting Bank (as the case may be) for any such reduction suffered will be paid to such Lender or such Fronting Bank (as the case may be) by the Borrower. It is acknowledged that this Agreement is being entered into by the Lenders and the Fronting Banks on the understanding that neither the Lenders nor the Fronting Banks will be required to maintain capital against their Commitments or agreements to issue Letters of Credit, as the case may be, under currently applicable laws, regulations and regulatory guidelines. In the event the Lenders or the Fronting Banks shall otherwise determine that such understanding is incorrect, it is agreed that the Lenders or the Fronting Banks, as the case may be, will be entitled to make claims under this subsection (b) based upon market requirements prevailing on the date hereof for commitments under comparable credit facilities against which capital is required to be maintained.

(c) A certificate of each Lender or the applicable Fronting Bank setting forth such amount or amounts as shall be necessary to compensate such Lender or such Fronting Bank (as the case may be) or its holding company as specified in subsection (a) or (b) above, as the case may be, and containing an explanation in reasonable detail of the manner in which such amount or amounts shall have been determined, shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay each Lender or Fronting Bank (as the case may be) the amount shown as due on any such certificate delivered by it within 10 days after its receipt of the same. Each Lender and each Fronting Bank shall give prompt notice to the Borrower of any event of which it has knowledge, occurring after the date hereof, that it has determined will require compensation by the Borrower pursuant to this Section; provided , however , that failure by such Lender or such Fronting Bank to give such notice shall not constitute a waiver of such Lender’s or such Fronting Bank’s (as the case may be) right to demand compensation hereunder.

(d) Failure on the part of any Lender or Fronting Bank to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital

23

with respect to any period shall not constitute a waiver of such Lender’s or such Fronting Bank’s (as the case may be) right to demand compensation with respect to such period or any other period; provided, however , that no Lender or Fronting Bank shall be entitled to compensation under this Section for any costs incurred or reductions suffered with respect to any date unless it shall have notified the Borrower that it will demand compensation for such costs or reductions under subsection (c) above not more than 90 days after the later of (i) such date and (ii) the date on which it shall have become aware of such costs or reductions. The protection of this Section shall be available to each Lender and each Fronting Bank regardless of any possible contention of the invalidity or inapplicability of the law, rule, regulation, guideline or other change or condition which shall have occurred or been imposed.

(e) Each Lender and each Fronting Bank agrees that it will designate a different lending office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the reasonable judgment of such Lender or such Fronting Bank (as the case may be) be disadvantageous to such Lender or Fronting Bank (as the case may be).

• SECTION 2.11. Change in Legality.

(a) Notwithstanding any other provision herein, if any change in any 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 Loan or to give effect to its obligations as contemplated hereby with respect to any Eurodollar Loan, then, by written notice to the Borrower and to the Agent, such Lender may:

• (i) declare that Eurodollar Loans will not thereafter be made by such Lender hereunder, whereupon any request for a Eurodollar Borrowing shall, as to such Lender only, be deemed a request for an ABR Loan unless such declaration shall be subsequently withdrawn (any Lender delivering such a declaration hereby agreeing to withdraw such declaration promptly upon determining that such event of illegality no longer exists); and

  (ii) require that all outstanding Eurodollar Loans made by it be converted to ABR Loans, in which event all such Eurodollar Loans shall be automatically converted to ABR Loans as of the effective date of such notice as provided in subsection (b) below.

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

(b) For purposes of this Section, a notice by any Lender shall be effective as to each Eurodollar Loan, if lawful, on the last day of the Interest Period currently applicable to such Eurodollar Loan; in all other cases such notice shall be effective on the date of receipt.

• SECTION 2.12. Pro Rata Treatment.

Except as required under Sections 2.10 and 2.15, each Borrowing, each payment or prepayment of principal of any Borrowing, each payment of interest on the Loans, each payment

24

of a reimbursement obligation in respect of a drawn Letter of Credit, each payment of the Commitment Fees, each reduction of the Total Commitment and each refinancing or conversion of any Borrowing with a Borrowing of any Type, shall be allocated pro rata among the Lenders in accordance with their respective Commitments (or, if such Commitments shall have expired or been terminated, in accordance with the respective principal amounts of their Outstanding Credits). For purposes of determining the Available Commitments of the Lenders at any time, the LC Outstandings shall be deemed to have utilized the Commitments of the Lenders pro rata in accordance with their respective Commitments at such time. Each Lender agrees that in computing such Lender’s portion of any Borrowing to be made hereunder, the Agent may, in its discretion, round each Lender’s percentage of such Borrowing to the next higher or lower whole dollar amount.

• SECTION 2.13. Sharing of Setoffs.

Each Lender agrees that if it shall, through the exercise of a right of banker’s lien, setoff or counterclaim, or pursuant to a secured claim under Section 506 of Title 11 of the United States Bankruptcy Code or other security or interest arising from, or in lieu of, such secured claim, received by such Lender under any applicable bankruptcy, insolvency or other similar law or otherwise, or by any other means, obtain payment (voluntary or involuntary) in respect of any Loans or LC Outstandings as a result of which the unpaid principal portion of its Loans and LC Outstandings shall be proportionately less than the unpaid principal portion of the Loans and LC Outstandings of any other Lender, it shall be deemed simultaneously to have purchased from such other Lender at face value, and shall promptly pay to such other Lender the purchase price for, a participation in the Loans or LC Outstandings of such other Lender, so that the aggregate unpaid principal amount of the Loans and LC Outstandings and participations in the Loans and LC Outstandings held by each Lender shall be in the same proportion to the aggregate unpaid principal amount of all Loans and LC Outstandings then outstanding as the principal amount of its Loans and LC Outstandings prior to such exercise of banker’s lien, setoff or counterclaim or other event was to the principal amount of all Loans and LC Outstandings outstanding prior to such exercise of banker’s lien, setoff or counterclaim or other event; provided, however , that, if any such purchase or purchases or adjustments shall be made pursuant to this Section and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored without interest. The Borrower expressly consents to the foregoing arrangements and agrees that any Lender holding a participation in a Loan or any LC Outstandings deemed to have been so purchased may exercise any and all rights of banker’s lien, setoff or counterclaim with respect to any and all moneys owing by the Borrower to such Lender by reason thereof as fully as if such Lender had made an Extension of Credit in the amount of such participation.

• SECTION 2.14. Payments.

(a) The Borrower shall make each payment (including principal of or interest on any Outstanding Credit or any Fees or other amounts) hereunder from an account in the United States not later than 12:00 noon, New York City time, on the date when due in dollars to the Agent at its offices at Two Penns Way, Suite 200, New Castle, Delaware 19720, Attention: Bank Loan Syndications, in immediately available funds. Each such payment shall be made without off-set,

25

deduction or counterclaim; provided , that the foregoing shall not constitute a relinquishment or waiver of the Borrower’s rights to any independent claim that the Borrower may have against the Agent, any Fronting Bank or any Lender.

(b) Whenever any payment (including principal of or interest on any Outstanding Credit or any Fees or other amounts) hereunder shall become due, or otherwise would occur, on a day that is not a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of interest or Fees, if applicable.

• SECTION 2.15. Taxes.

(a) Any and all payments of principal and interest on any of the Outstanding Credits or of any Fees or indemnity or expense reimbursements by the Borrower hereunder (" Borrower Payments ") shall be made, in accordance with Section 2.14, free and clear of and without deduction for any and all current or future United States Federal, state and local taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect to the Borrower Payments, but only to the extent reasonably attributable to the Borrower Payments, excluding (i) income taxes imposed on the net income of the Agent, any Fronting Bank or any Lender (or any transferee or assignee thereof, including a participation holder (any such entity a " Transferee ")) and (ii) franchise taxes imposed on the net income of the Agent, any Fronting Bank or any Lender (or Transferee), in each case by the jurisdiction under the laws of which the Agent, such Fronting Bank or such Lender (or Transferee) is organized or doing business through offices or branches located therein, or any political subdivision thereof (all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings and liabilities, collectively or individually, " Taxes "). If the Borrower shall be required to deduct any Taxes from or in respect of any sum payable hereunder to any Lender (or any Transferee) or the Agent, or any Fronting Bank (i) the sum payable shall be increased by the amount (an " additional amount ") necessary so that after making all required deductions (including deductions applicable to additional amounts payable under this Section) such Lender (or Transferee) or the Agent or such Fronting Bank (as the case may be) shall receive an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall
