(New York City time) on the date of such Borrowing in the case of a Borrowing consisting of Eurodollar Rate Advances, or 2:00 P.M. (New York City time) on the date of such Borrowing in the case of a Borrowing consisting of Base Rate Advances, make such funds available to such Borrower at the Administrative Agent’s address referred to in Section 8.02.

(b) Anything in subsection (a) above to the contrary notwithstanding, neither Borrower may select Eurodollar Rate Advances for any Borrowing if the obligation of the Lenders to make Eurodollar Rate Advances shall then be suspended pursuant to Section 2.07 or 2.11.

(c) In the case of any Borrowing that the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower that has requested such Advances shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III, including any loss (excluding

loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date.

(d) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s ratable portion of such Borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the date of such Borrowing in accordance with subsection (a) of this Section 2.02 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower that has requested such Advance on such date a corresponding amount. If and to the extent that such Lender shall not have so made such ratable portion available to the Administrative Agent, such Lender and such Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to such Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of such Borrower, the interest rate applicable at the time to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement.

(e) The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing.

SECTION 2.03 Fees. (a) Facility Fee. The Borrowers jointly and severally agree to pay to the Administrative Agent for the account of each Lender a facility fee, for each day (i) from the Effective Date, if such Lender shall be a party hereto on the Effective Date, or from the effective date specified in the Assignment and Acceptance pursuant to which it became a Lender or from the date it became a Lender pursuant to Section 2.16 or 2.17, if such Lender shall become a party hereto after the Effective Date, until the Commitment Termination Date, at the Facility Fee Rate for such date on the amount of such Lender’s Commitment for such date and (ii) from the Commitment Termination Date, if such Lender shall be a party hereto on the Commitment Termination Date, or from the effective date specified in the Assignment and Acceptance pursuant to which it became a Lender, if such Lender shall become a party hereto after the Commitment Termination Date, until the Maturity Date, at the Facility Fee Rate for such date on the aggregate outstanding principal amount of such Lender’s Advances for such date; in each case payable in arrears quarterly on the final day of each March, June, September and December, commencing September, 2002, and on the Commitment Termination Date and the Maturity Date, as the case may be.

(b) Administrative Agent’s Fees. The Borrowers jointly and severally agree to pay to the Administrative Agent for its own account such fees as may from time to time be agreed between the Borrowers and the Administrative Agent.

SECTION 2.04 Termination or Reduction of the Commitments. The Borrowers shall have the right, upon at least three Business Days’ notice signed by both Borrowers to the Administrative Agent, to terminate in whole or reduce ratably in part the unused portions of the respective Commitments of the Lenders, provided that each partial reduction shall be in the aggregate amount of $1,000,000 or an integral multiple of $1,000,000 in excess thereof.

SECTION 2.05 Repayment. Each Borrower shall repay on the Maturity Date to the Administrative Agent for the ratable account of the Lenders the aggregate principal amount of any Advances made to such Borrower and outstanding on the Commitment Termination Date.

SECTION 20.6 Interest. (a) Scheduled Interest. Each Borrower shall pay interest on the unpaid principal amount of each Advance made to such Borrower owing to each Lender from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum:

(i) Base Rate Advances. During such periods as such Advance is a Base Rate Advance, a rate per annum equal at all times to the Base Rate in effect from time to time, payable in arrears monthly on the final day of each month during such periods and on the date such Base Rate Advance shall be Converted or paid in full.

(ii) Eurodollar Rate Advances. During such periods as such Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during each Interest Period for such Advance to the sum of (A) the Eurodollar Rate for such Interest Period for such Advance plus (B) the Applicable Margin in effect from time to time, payable in arrears on the final day of such Interest Period and, if such Interest Period has a duration of more than three months, on each day that occurs during such Interest Period every three months from the first day of such Interest Period and on the date such Eurodollar Rate Advance shall be Converted or paid in full.

(b) Default Interest. Upon the occurrence and during the continuance of a Default under Section 6.01(a) as a consequence of any failure by either Borrower to pay when due hereunder any amount of principal, interest, fee or other amount payable hereunder, such Borrower shall pay interest (before and after judgment) on such amount of principal, interest, fee or other amount that is not paid when due, from the date such Default shall occur until such amount shall be paid in full, payable in arrears on the date such amount shall be paid in full and on demand, at a rate per annum equal at all times to the sum of the Base Rate in effect from time to time plus 2% per annum. Any interest payable pursuant to this Section 2.06(b) on any amount of principal of an Advance shall be in lieu of interest which would otherwise be payable on such amount of principal pursuant to Section 2.06(a).

(c) Additional Interest on Eurodollar Rate Advances. Each Borrower shall pay to each Lender, so long as and to the extent 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 Rate Advance of such Lender made to such Borrower, from the date of such Eurodollar Rate 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 then existing 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. Each Lender shall, as promptly as practicable after an authorized officer of such Lender having direct and ongoing involvement in the decisions made in respect of this Agreement obtains knowledge of such circumstances and the determination of such Lender to request additional interest from such Borrower pursuant to this Section 2.06(c), provide notice to the Administrative Agent and such Borrower of the circumstances entitling such Lender to such additional interest, which notice shall (A) specify the amount of any such additional interest incurred in connection with such Eurodollar Rate Advance made to such Borrower and/or to be incurred in connection with Eurodollar Rate Advances made by such Lender from time to time thereafter to such Borrower and (B) certify that such Lender’s claim for payment of such additional interest is not inconsistent with its treatment of other borrowers that, as a credit matter, are substantially similar to such Borrower and that are subject to comparable provisions in the loan or other credit documentation to which such borrowers are parties; provided, however, that no Lender shall be entitled to additional interest on any Eurodollar Rate Advance pursuant to this Section 2.06(c) for any Interest Period ending more than 120 days prior to the date that notice of such additional interest is first provided by such Lender to such Borrower. A notice delivered by any Lender to either Borrower pursuant to the terms of this Section 2.06(c) shall be conclusive and binding, absent manifest error. A Lender that delivers a notice under this Section 2.06(c) shall promptly notify the Administrative Agent and such Borrower if the circumstances that gave rise to such notice no longer exist.

SECTION 2.07 Interest Rate Determination. (a) The Administrative Agent shall give prompt notice to each Borrower and the Lenders of the applicable interest rate determined by the Administrative Agent for purposes of Section 2.06(a)(i) or (ii) or 2.06(b).

(b) If either Borrower shall fail to select the duration of any Interest Period for any Eurodollar Rate Advances to be made to such Borrower in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01, the Administrative Agent will forthwith so notify such Borrower and the Lenders and such Advances will automatically, on the final day of the then existing Interest Period therefor, Convert into Base Rate Advances.

(c) On the date on which the aggregate unpaid principal amount of Eurodollar Rate Advances having the same Interest Period shall be reduced, by payment or prepayment or otherwise, to less than $5,000,000, such Advances shall automatically Convert into Base Rate Advances.

(d) Upon the occurrence and during the continuance of any Event of Default, (i) each Eurodollar Rate Advance will automatically, on the final day of the then existing Interest Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended.

SECTION 2.08 Optional Conversion of Advances. Each Borrower may on any Business Day, upon notice given to the Administrative Agent not later than 12:00 A.M. (New York City time) on the third Business Day prior to the date of the proposed Conversion and subject to the provisions of Sections 2.07 and 2.11, Convert all Advances of one Type made

to such Borrower comprising the same Borrowing into Advances of the other Type; provided, however, that (a) any Conversion of Eurodollar Rate Advances into Base Rate Advances shall be made only on the final day of an Interest Period for such Eurodollar Rate Advances and (b) no Conversion of any Advances shall result in more separate Interest Periods with respect to Eurodollar Rate Advances made to such Borrower than permitted under the definition of the term “Interest Period” in Section 1.01. Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Advances to be Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the duration of the initial Interest Period for each such Advance.

SECTION 2.09 Optional Prepayments. Each Borrower may, upon at least three Business Days’ notice, or, in the case of Base Rate Advances, upon same day’s prior notice, to the Administrative Agent stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given such Borrower shall, prepay the outstanding principal amount of the Advances made to such Borrower comprising part of the same Borrowing in whole or ratably in part, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided, however, that (i) no such prepayment of any Eurodollar Rate Advance may be made on any day other than the final day of the Interest Period for such Advance and (ii) all such partial prepayments shall be in an aggregate minimum amount of $500,000 (or, in the case of Eurodollar Rate Advances, $1,000,000) and an integral multiple of $100,000. Each prepayment of any Advances made pursuant to this Section 2.09 shall be without premium or penalty.

SECTION 2.10 Increased Costs. If, due to either (a) the introduction of or any change after the date hereof in or in the interpretation of any law or regulation or (b) the compliance with any guideline or request promulgated after the date hereof from any central bank or other governmental authority (whether or not having the force of law), there shall be any increase in (i) the cost to any Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Advances (excluding for purposes of this Section 2.10 any such increased costs resulting from Taxes or Other Taxes or from changes in the basis or rate of taxation of net income or gross income by the United States or by the foreign jurisdiction or state under the laws of which such Lender is subject to tax as a result of a present or former connection between such Lender and such foreign jurisdiction or state) or (ii) the amount of capital required to be maintained by such Lender or any corporation controlling such Lender based on the existence of its Commitment hereunder, then the Borrowers jointly and severally agree from time to time, within five Business Days after receipt by both Borrowers of a written demand by such Lender (with a copy of such demand to the Administrative Agent), to pay to the Administrative Agent for the account of such Lender additional amounts as shall accrue from and after the date of demand by such Lender to compensate such Lender for such increased cost or such increase of capital; provided, however, that before making any such demand, each Lender agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to minimize such additional amounts and to designate a different Applicable Lending Office if the making of such a designation would avoid the need for, or reduce the amount of, such increased cost or such increase of capital and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender; and provided, further, that the Borrowers shall be required jointly and severally to pay to such Lender only such additional amounts as shall be required to compensate such Lender for such increased cost or such increase of capital as shall

accrue from and after the date of demand by such Lender. In determining such additional amounts, such Lender will act reasonably and in good faith and will use averaging and attribution methods which are reasonable, provided that such Lender’s determination of compensation owing under this Section 2.10 shall be conclusive and binding, absent manifest error. Each Lender, upon determining that any additional amounts will be payable pursuant to this Section 2.10, will give prompt written notice thereof to the Borrowers, which notice shall show the basis for the calculation of such additional amounts. Notwithstanding anything herein to the contrary, either Borrower shall have the right to unilaterally terminate the Commitment of any Lender demanding additional amounts under this Section 2.10 sixty (60) days after providing to such Lender a notice of termination; provided that such termination shall not result in a reduction in amounts required to be paid pursuant to this Section 2.10. Each of the Borrowers shall, concurrent with such termination, pay or prepay, as the case may be, to such Lender the aggregate amount, if any at such time, of all Advances and other amounts payable by such Borrower to such Lender under this Agreement. Notwithstanding any provision of this Agreement to the contrary, Section 2.13 shall provide the exclusive remedy to the Lenders in respect of Taxes and Other Taxes.

SECTION 2.11 Illegality. Notwithstanding any other provision of this Agreement, if any Lender shall notify the Administrative Agent that the introduction of or any change after the date hereof in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority asserts after the date hereof that it is unlawful, for any Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, (i) each Eurodollar Rate Advance will automatically, upon such demand, Convert into a Base Rate Advance and (ii) the obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Administrative Agent shall notify the Borrower that has requested such Advance and the Lenders that the circumstances causing such suspension no longer exist; provided, however, that before making any such demand, each Lender agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Eurodollar Lending Office if the making of such a designation would allow such Lender or its Eurodollar Lending Office to continue to perform its obligations to make Eurodollar Rate Advances or to continue to fund or maintain Eurodollar Rate Advances and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

SECTION 2.12 Payments and Computations. (a) Each Borrower shall make each payment to be made by it hereunder and under the Notes not later than 11:00 A.M. (New York City time) on the day when due in U.S. dollars to the Administrative Agent at the Administrative Agent’s Account in same day funds and without set-off or counterclaim. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest ratably (other than amounts payable pursuant to Section 2.10, 2.13 or 8.04(c)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 8.07(d), from and after the effective date specified in such Assignment and Acceptance, the Administrative

Agent shall make all payments hereunder and under the Notes in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b) All computations of interest based on the Base Rate and of facility fees shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate or the Federal Funds Rate shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or facility fees are payable. Each determination by the Administrative Agent of an interest rate hereunder shall be conclusive and binding, absent manifest error.

(c) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or facility fee, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next succeeding calendar month, such payment shall be made on the next preceding Business Day.

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

SECTION 2.13 Taxes. (a) Any and all payments by each Borrower hereunder or under the Notes shall be made, in accordance with Section 2.12, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings imposed by the United States or by any political subdivision thereof or therein with respect to such payments, and all penalties and interest with respect, thereto, excluding, in the case of each Lender and the Administrative Agent, taxes imposed on or measured by its net income or net profit, and branch profit taxes, franchise taxes, taxes on doing business and taxes measured by or imposed upon its capital or net worth, in each case imposed as a result of a present or former connection between the Administrative Agent or such Lender and the jurisdiction imposing such tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from the Administrative Agent or such Lender having executed, delivered or performed its obligations or received a payment under, or enforced this Agreement or the Notes) (all such non-excluded taxes, levies, imposts, deductions, charges,

withholdings and liabilities in respect of payments hereunder or under the Notes being hereinafter referred to as “Taxes”). If either Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable by such Borrower hereunder or under any Note to any Lender or the Administrative Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.13) such Lender or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower shall make such deductions and (iii) such Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) In addition, the Borrowers jointly and severally agree to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from the execution, delivery or registration of this Agreement or the Notes (hereinafter referred to as “Other Taxes”); provided, however, that the Borrowers shall have no obligation to pay Other Taxes that may arise as a result of a participation referred to in Section 2.14 or 8.07.

(c) Each of the Borrowers shall indemnify each Lender and the Administrative Agent for and hold it harmless against the full amount of Taxes with respect to payments by such Borrower hereunder or under the Notes imposed on or paid by such Lender or the Administrative Agent (as the case may be) and any liability for penalties, interest and expenses arising therefrom or with respect thereto. The Borrowers shall jointly and severally indemnify each Lender and the Administrative Agent for and hold it harmless against the full amount of Other Taxes imposed on or paid by such Lender or the Administrative Agent (as the case may be) and any liability for penalties, interest and expenses arising therefrom or with respect thereto. Any indemnification under this Section 2.13(c) shall be made within 30 days from the date such Lender or the Administrative Agent (as the case may be) makes written demand therefor.

(d) Each Lender that is not a “United States person” within the meanings specified in Section 7701 of the Code, on or prior to the date of its execution and delivery of this Agreement or on the date of the Assignment and Acceptance pursuant to which it becomes a Lender, as the case may be, and from time to time thereafter as requested in writing by either Borrower (but only so long as such Lender remains lawfully able to do so), shall provide each of the Administrative Agent and such Borrower with (i) two accurate and complete original signed copies of Internal Revenue Service Form W-8BEN or W-8ECI, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying to such Lender’s entitlement to a complete exemption from United States withholding tax with respect to payments to be made under this Agreement or the Notes on account of such Lender being entitled to benefits under an income tax treaty or such payments being effectively connected with such Lender’s conduct of a United States trade or business or (ii) if the Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code and cannot deliver either Internal Revenue Service Form W-8BEN or W-8ECI pursuant to clause (i) above, (A) a certificate in form and substance satisfactory to the Administrative Agent and such Borrower stating that such Lender is not a “person” described in Section 871(h)(3) or Section 881(c)(3) of the Code (a “Foreign Lender Certificate”) and (B) two accurate and complete original signed copies of Internal Revenue

Service Form W-8BEN (or successor form) certifying to such Lender’s entitlement to a complete exemption from United States withholding tax with respect to payments to be made under this Agreement and under any Note. In addition, each Lender agrees that from time to time, when a lapse in time or change in circumstances renders the previous certification obsolete or inaccurate in any material respect, it will deliver to such Borrower and the Administrative Agent two new accurate and complete original signed copies of Internal Revenue Service Form W-8BEN or W-8ECI, or Form W-8BEN and a Foreign Lender Certificate, as the case may be, and such other forms as may be required in order to confirm or establish the entitlement of such Lender to a continued exemption from United States withholding tax with respect to payments under this Agreement and any Note or it shall immediately notify such Borrower and the Administrative Agent of its inability to deliver any such form or certificate, in which case such Lender shall not be required to deliver any such form or certificate pursuant to this Section 2.13(d) for so long as such payments may be made free from United States withholding tax. Notwithstanding the foregoing, no Lender shall be required to deliver any such form or certificate described in the immediately preceding sentence if a change in treaty, law or regulation has occurred prior to the date on which such delivery would otherwise be required that renders any such form or certificate inapplicable or would prevent the Lender from duly completing and delivering any such form or certificate with respect to it and such Lender so advises such Borrower.

(e) For any period with respect to which a Lender has failed to provide either Borrower with the appropriate form described in Section 2.13(d), such Lender shall not be entitled to indemnification under Section 2.13(a) or (c) with respect to Taxes or Other Taxes imposed by the United States by reason of such failure.

(f) Any Lender claiming additional amounts payable pursuant to this Section 2.13 agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to minimize such additional amounts and to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable determination of such Lender, be otherwise disadvantageous to such Lender.

(g) If a Lender changes its Applicable Lending Office (other than pursuant to subsection (f) above or Section 2.11 or 2.12 or otherwise at the request of either Borrower) and the effect of such change, as of the date of such change, would be to cause either Borrower to become obligated to pay any additional amounts under subsection 2.14, such Borrower shall not be obligated to pay such additional amounts.

(h) If either Borrower is required to pay any amounts pursuant to the provisions of this Section 2.13 to or for the account of any Lender or the Administrative Agent, and if thereafter such Lender or the Administrative Agent, as the case may be, shall receive a refund of any Taxes or Other Taxes paid by or on behalf of such Lender or the Administrative Agent, as the case may be, that such Lender or the Administrative Agent, as the case may be, reasonably determines to relate solely to the amounts so paid by such Borrower, such Lender or the Administrative Agent, as the case may be, shall to the extent that it can do so without prejudice to the retention of the amount of such refund, pay to such Borrower within twenty days after the date on which such Lender or the Administrative Agent, as the case may be, actually receives such refund in an amount which such Lender or the Administrative Agent, as the case

may be, determines to be the proportion of the refunded amount as will leave it, after such remittance, in no better or worse position than it would have been if the Taxes or Other Taxes had not been imposed and the corresponding additional amounts or indemnification payment not been made. Nothing in this Section 2.13(h) shall be construed as requiring any Lender or the Administrative Agent to conduct its business or to arrange or alter in any respect its tax or financial affairs so that it is entitled to receive such refund. Neither a Lender nor the Administrative Agent shall be obligated to disclose information regarding its tax affairs or computations to either Borrower in connection with this clause (h).

SECTION 2.14 Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances owing to it (other than pursuant to Section 2.10, 2.13 or 8.04(c)) in excess of its ratable share of payments on account of the Advances obtained by all the Lenders, such Lender shall forthwith purchase from the other Lenders such participations in the Advances owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (a) the amount of such Lender’s required repayment to (b) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrowers agree that any Lender so purchasing a participation from another Lender pursuant to this Section 2.14 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of either Borrower in the amount of such participation.

SECTION 2.15 Use of Proceeds. Each Borrower shall use the proceeds of each Advance for general corporate or company purposes of such Borrower and its Subsidiaries.

SECTION 2.16 Extension of Commitment Termination Date. (a) Within 30 days prior to the then scheduled Commitment Termination Date (but no later than the twentieth day prior to the then scheduled Commitment Termination Date), the Borrowers may make a written request (an “Extension Request”) to the Administrative Agent who shall forward a copy to each Lender that the Commitment Termination Date be extended to the date that occurs exactly 364 days after the then scheduled Commitment Termination Date. Such Extension Request shall include a certification by a senior officer of each Borrower that no Default or Event of Default has occurred and is continuing and all representations and warranties contained herein are true and correct in all material aspects on and as of the date of the Extension Request (it being understood and agreed that any representation or warranty which expressly refers by its terms to a specified date shall be required to be true and correct in all material respects only as of such date). Each Lender that agrees to such Extension Request shall so notify the Administrative Agent and the Borrowers in writing on or prior to the date occurring 10 days after the Administrative Agent’s receipt of such Extension Request by indicating such agreement on counterparts of the Extension Request and delivering such counterpart to the Administrative Agent and the Borrowers; provided that any failure to so notify the Administrative Agent and the Borrowers shall be deemed to be a disapproval by such Lender of the Borrowers’ Extension

Request. The Commitment of any Lender which does not so agree shall terminate upon the Commitment Termination Date then in effect. No Lender shall be obligated to grant any extension pursuant to this Section 2.16 and any such extension shall be in the sole discretion of each Lender.

(b) If less than all of the Lender’s consent to an Extension Request (each Lender that has not so consented being a “Declining Lender”, and each other Lender being an “Extending Lender”), the Borrowers shall have the right to require any Declining Lender to assign in full its rights and obligations under this Agreement (i) to any one or more Extending Lenders designated by the Borrowers that have offered in their returned counterpart of the Extension Request to increase their respective Commitments in an aggregate amount at least equal to the amount of such Declining Lender’s Commitment (each such Extending Lender being an “Increasing Extending Lender”) and (ii) to the extent of any shortfall in the aggregate amount of extended Commitments, to any one or more Eligible Transferees designated by the Borrowers that agree to assume all of such rights and obligations (each such Eligible Transferees being a “Replacement Lender”), provided that (A) such Declining Lender shall have received payment of all amounts owing under its Note and this Agreement on the effective date of such assignment, (B) such assignment shall otherwise have occurred in compliance with Section 8.07 and (C) the effective date of such assignment shall be the date specified by the Borrowers and agreed to by the Replacement Lender or Increasing Extending Lender, as the case may be, which date shall be on or prior to the applicable Commitment Termination Date.

(c) If (and only if) the sum of (i) the Commitments of the Extending Lenders and the Replacement Lenders plus (ii) the additional Commitments of the Increasing Extending Lenders shall be greater than 50% of the aggregate amount of the Commitments in effect on the then scheduled Commitment Termination Date, then, effective as of the then scheduled Commitment Termination Date, the “Commitment Termination Date” shall be extended to the date occurring 364 days after the Commitment Termination Date then in effect (except that, if such date is not a Business Day, such Commitment Termination Date as so extended shall be the next preceding Business Day) and each Replacement Lender shall thereupon become a “Lender” for all purposes of this Agreement.

SECTION 2.17 Increase of Commitments. (a) The Borrowers may, at any time but in any event not more than one time during any period of six consecutive calendar months, make a written request (an “Increase Request”) to the Administrative Agent (who shall forward a copy to each Lender) that the Commitments of the Lenders be increased by an aggregate amount, together with the aggregate amount by which the Commitments of the Lenders were previously increased pursuant to this Section 2.17, not to exceed $100,000,000 in excess of the aggregate amount of the Commitments as of the date of this Agreement. Such Increase Request shall include a certification by a senior officer of each Borrower that no Default or Event of Default has occurred and is continuing and all representations and warranties contained herein are true and correct in all material respects on and as of the date of the Increase Request (it being understood and agreed that any representation or warranty which expressly refers by its terms to specified date shall be required to be true and correct in all material respects only as of such date). Any such increase in Commitments shall be effective as of a date (the “Increase Date”) specified in the related Increase Notice that is (i) prior to the Commitment Termination Date and (ii) at least 10 days after the date of such Increase Notice. Each Increase Notice shall specify the

date by which Lenders who wish to increase their Commitment must consent to such increase (the “Commitment Date”), which date shall be no later than five Business Days prior to the related Increase Date. Each Lender that is willing to increase its Commitment (each an “Increasing Lender”), shall notify the Administrative Agent on or prior to the Commitment Date of the amount by which it is willing to increase its Commitment, which amount shall not exceed the respective amount specified in the relevant Increase Notice. No Lender shall be obligated to increase its Commitment pursuant to this Section 2.17 and any such increase shall be in the sole discretion of each Lender. If the Lenders notify the Administrative Agent that they are willing to increase the amount of their respective Commitments by an aggregate amount that exceeds the amount of the requested increase, the requested increase shall be allocated among the Lenders willing to participate therein ratably in accordance with the amount by which they offered to increase their respective Commitments on the Commitment Date.

(b) Promptly following each Commitment Date, the Administrative Agent shall notify the Borrowers as to the amount, if any, by which the Lenders are willing to participate in the requested increase. If the aggregate amount by which the Lenders are willing to increase their Commitments on any such Commitment Date is less than the requested amount, then any one or more Eligible Transferees designated by the Borrowers that agree to provide Commitments for the shortfall may become party to this Agreement by executing and delivering, together with the Borrowers, an accession agreement pursuant to which such Eligible Transferee shall become a party to this Agreement and, to the extent provided therein, shall have the rights and obligations of a Lender hereunder.

(c) On each Increase Date, each Eligible Transferee that accepts an offer to participate in a requested Commitment increase in accordance with Section 2.17(b) shall become a Lender party to this Agreement as of such Increase Date and the Commitment of each Increasing Lender shall be increased as of such Increase Date by the amount set forth in its notice delivered to the Administrative Agent in accordance with Section 2.17(a) (or by the amount allocated to such Lender pursuant to the last sentence of Section 2.17(a)).

company, corporation or partnership, as the case may be, in each jurisdiction where the nature of its business requires such registration or qualification and (iii) holds all requisite governmental licenses, permits and other approvals to own and hold under lease its property and to conduct its business substantially as conducted by it, except where the failure to be so qualified or hold such licenses, permits and approvals, singly or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

Since December 31, 2001, there has been no Material Adverse Change.

(f) There is no pending or, to the knowledge of each Borrower, threatened litigation, action, proceedings or labor controversy affecting such Borrower or any Material Subsidiary or any of its respective properties, businesses, assets or revenues which may reasonably be expected to have a Material Adverse Effect or which purports to affect the legality, validity or enforceability of any Loan Document.

With respect to its Commitment, the Advances made by it and the Note or Notes issued to it, each Agent shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not an Agent; and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include each Agent in its individual capacity. Each Agent and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of, accept investment banking engagements from and generally engage in any kind of business with, the Borrowers, any of their Subsidiaries and any Person who may do business with or own securities of either Borrower or any such Subsidiaries, all as if such Agent was not an Agent and without any duty to account therefor to the Lenders.

SECTION 8.04 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender and based on the financial statements referred to in Section 4.01 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.

(collectively, the “Indemnified Costs”), provided that no Lender shall be liable for any portion of the Indemnified Costs resulting from the Administrative Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket fees and expenses (including counsel fees and expenses) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that the Administrative Agent is not reimbursed for such fees and expenses by the Borrowers. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 7.05 applies whether any such investigation, litigation or proceeding is brought by the Administrative Agent, any Lender or a third party.

SECTION 7.06 Successor. The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Borrowers and may be removed at any time with or without cause by the Required Lenders.

After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement.

$300 Million Credit Agreement

Ladies and Gentlemen:

This opinion is delivered to you pursuant to Section 3.01(d)(vii) of the Credit Agreement dated as of August 1, 2002 (the “Credit Agreement”), among Ambac Financial Group, Inc., a Delaware corporation (“Ambac Financial”), Ambac Assurance Corporation, a Wisconsin stock insurance corporation, each of you as Lenders, The Bank of New York, as Syndication Agent and The Bank of Nova Scotia, as Administrative Agent for the Lenders (the “Administrative Agent”). Unless otherwise defined herein, terms defined in the Credit Agreement are used herein as therein defined.

I am First Vice President, Assistant General Counsel and Secretary of Ambac Financial and have acted as counsel to Ambac Financial in connection with the preparation, execution and delivery of the Credit Agreement. In that connection, I have examined:

1)		the Credit Agreement;

2)		the Notes dated the date hereof, executed by Ambac Financial and payable to each of you as Lenders (the “Ambac Financial Notes”);

3)		the Amended and Restated Certificate of Incorporation of Ambac Financial and all amendments thereto (the “Charter”); and

4)		the By-laws of Ambac Financial and all amendments thereto (the “By-laws”).

I also have examined and am familiar with the originals, or copies certified or otherwise identified to my satisfaction, of such documents and corporate records of Ambac Financial, certificates of public officials and officers of Ambac Financial and agreements,

E-1

instruments and other documents, as I have deemed necessary as a basis for the opinions expressed below. As to questions of fact material to such opinions, I have, when relevant facts were not independently established by me, relied, to the extent I deemed appropriate, upon certificates of Ambac Financial or its officers, or of public officials. In addition, I have also assumed the genuineness of all signatures, the authenticity of all documents submitted to me as originals and the conformity with originals of all documents submitted to me as copies thereof. I have also assumed the due execution and delivery, pursuant to due authorization, of the Credit Agreement by each of the Lenders and the Administrative Agent.

I am qualified to practice law in the State of New York. I do not purport to express any opinion herein as to the laws of any jurisdiction other than the laws of the State of New York, the General Corporation Law of the State of Delaware and the Federal laws of the United States of America.

Based upon the foregoing and upon such investigation, as I have deemed necessary, I am of the following opinion:

(1) Ambac Financial is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware. Ambac Financial is duly

qualified to do business and is in good standing as a foreign corporation in each jurisdiction where the nature of its business requires such qualification, except where the failure to be so qualified, singly or in the aggregate, would not have a Material Adverse Effect.

(2) The execution, delivery and performance by Ambac Financial of the Credit Agreement and the Ambac Financial Notes are within Ambac Financial’s corporate powers, and have been duly authorized by all necessary corporate action on the part of Ambac Financial.

(3) There is no pending or, to my knowledge, threatened action, suit, investigation, litigation, proceeding or labor controversy affecting Ambac Financial before any court, governmental agency or arbitrator which (A) purports to affect the legality, validity or enforceability of the Credit Agreement or any of the Ambac Financial Notes or the consummation of the transactions contemplated thereby or (B) which could be reasonably likely to have a Material Adverse Effect.

(4) The execution, delivery and performance by Ambac Financial of the Credit Agreement and the Ambac Financial Notes do not (i) violate or contravene its Charter or By-laws, or any contractual restriction or law applicable to Ambac Financial or any rule or regulation applicable to Ambac Financial or (ii) result in, or require the creation or imposition of, any Lien on any of Ambac Financial’s properties.

(5) The execution, delivery and performance by Ambac Financial of the Credit Agreement and the Ambac Financial Notes do not conflict with or result in a breach of any of the terms or provisions of, or constitute a default under (i) any indenture, loan agreement, lease, guarantee, mortgage or other agreement or instrument, or (ii) any order, writ, judgment, award, injunction or decree known to me to which Ambac

E-2

Financial is a party or by which it is bound or to which any of its properties or assets are subject, except for such conflicts, breaches or defaults, which individually or in the aggregate, would not have any Material Adverse Effect and would not have a material adverse effect on the legality, validity, binding effect or enforceability of the Credit Agreement or the Ambac Financial Notes.

(6) No authorization, approval or other action by, and no notice to or filing with, any governmental authority or regulatory body is required for the due execution, delivery and performance by Ambac Financial of the Credit Agreement or any Ambac Financial Note.

(7) The Credit Agreement and the Ambac Financial Notes have been duly executed and delivered on behalf of Ambac Financial.

A copy of this opinion letter may be delivered by each of you to any Eligible Assignee in connection with and at the time of any assignment and delegation by either of you as a Lender to such Eligible Assignee of a portion of your Loans and Commitment in accordance with the provisions of the Credit Agreement, and such Eligible Assignee may rely on the opinions expressed above with respect to the Credit Agreement as if this opinion letter were addressed and delivered to such Eligible Assignee on the date hereof.

QUALIFICATIONS AND ASSUMPTIONS

OPINION

Based solely upon the foregoing and subject to the qualifications and assumptions stated above, in our opinion:

We have no reason to believe that any such term violates an important public policy of the State of Wisconsin.

(5) Assuming that the Credit Agreement and the Ambac Assurance Notes are legal, valid, binding and enforceable under the law of the State of New York, the Credit Agreement and the Ambac Assurance Notes constitute the legal, valid and binding obligations of Ambac Assurance, and are enforceable against Ambac Assurance in accordance with their respective terms.

SHEARMAN & STERLING

[Effective Date]

To each of the Lenders listed on

Schedule I hereto and

The Bank of Nova Scotia,

as Administrative Agent

Ambac Financial Group, Inc. and Ambac Assurance Corporation

Ladies and Gentlemen:

This opinion is furnished to you pursuant to Section 3.01(d)(x) of the Credit Agreement dated as of August 1, 2002 (the “Credit Agreement”), among Ambac Financial Group, Inc. and Ambac Assurance Corporation (the “Borrowers”), the Lenders parties thereto, The Bank of New York, as Syndication Agent, and The Bank of Nova Scotia, as Administrative Agent for said Lenders. Terms defined in the Credit Agreement are used herein as therein defined.

We have acted as special New York counsel for the Borrowers in connection with the preparation, execution and delivery of the Credit Agreement.

In that connection, we have examined:

(1) The Credit Agreement.

(2) The documents furnished by each Borrower pursuant to Article III of the Credit Agreement, including the Notes furnished by each Borrower thereunder on the date hereof (for purposes of this opinion letter, the “Notes”).

We have also examined the originals, or copies certified to our satisfaction, of such certificates of officers of each Borrower and agreements, instruments, other documents, as we have deemed necessary as a basis for the opinions expressed below. As to questions of fact material to such opinions, we have, when relevant facts were not independently established by us, relied upon certificates of each Borrower

In our examination of the documents, certificates and instruments referred to above, we have assumed the authenticity of all such documents, certificates and instruments submitted to us as originals, the genuineness of all signatures, the due authority of the parties executing such documents, certificates and instruments, and the conformity to the originals of all such documents, certificates or instruments submitted to us as copies. We have also assumed, without independent investigation, that (a) each Borrower (i) is a corporation duly formed and validly existing under the laws of the state of its formation and (ii) has full power and authority to enter into and perform its obligations under the Credit Agreement and the Notes, (b) the execution, delivery and performance by each Borrower of the Credit Agreement and the Notes

H-1

have been duly authorized by all necessary board, company, member, manager or officer action and do not violate or contravene any law, rule or regulation applicable to either Borrower or any agreement, instrument or other document binding on or affecting either Borrower or any constituent document of either Borrower, (c) no authorization, approval or other action by, and no notice to or filing with, any governmental authority or regulatory body or any other Person is required for the due execution, delivery or performance by either Borrower of the Credit Agreement or the Notes, or if any such authorization, approval, action, notice or filing is required therefor, it has been duly obtained or made and is in full force and effect, (d) the Credit Agreement has been duly executed and delivered, with all necessary power and authority (corporate and otherwise), by each of you, and (e) the Credit Agreement and the Notes have been duly executed and delivered on behalf of such Borrower.

Based upon the foregoing and upon such investigation as we have deemed necessary and subject to the qualifications set forth below, we are of the opinion that the Credit Agreement is, and if an Advance were made, each of the Notes evidencing such Advance would be, the legal, valid and binding obligations of each Borrower, enforceable against each Borrower in accordance with their respective terms.

Our opinion above is subject to the following qualifications:

(a) Our opinion is subject to the effect of any applicable bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar law affecting creditors’ rights generally.

(b) Our opinion is also subject to the effect of general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether considered in a proceeding in equity or at law).

(c) We express no opinion (i) as to the enforceability of the indemnification provisions set forth in Section 8.04(b) of the Credit Agreement to the extent enforcement thereof is contrary to the public policy regarding exculpation of criminal violations, intentional harm and acts of gross negligence or recklessness and (ii) as to the effect of the law of any jurisdiction other than the State of New York wherein any Lender may be located or wherein enforcement of the Credit Agreement or the Notes may be sought that limits the rates of interest legally chargeable or collectible.

Our opinion is limited to the law of the State of New York and the federal law of the United States, and we do not express any opinion herein concerning any other law.

A copy of this opinion letter may be delivered by each of you to any Eligible Assignee in connection with and at the time of any assignment and delegation by any of you as a Lender to such Eligible Assignee of a portion of your Advances and Commitment in accordance with the provisions of the Credit Agreement, and such Eligible Assignee may rely on the opinion expressed above with respect to the Credit Agreement as if this opinion letter were addressed and delivered to such Eligible Assignee on the date hereof.

This opinion letter speaks only as of the date hereof. We expressly disclaim any responsibility to advise any of you or any other Person who is permitted to rely on the opinion

H-2

expressed herein as specified in the next preceding paragraph of any development or circumstance of any kind including any change of law or fact that may occur after the date of this opinion letter even though such development, circumstance or change may affect the legal analysis, a legal conclusion or any other matter set forth in or relating to this opinion letter. Accordingly, any Lender relying on this opinion letter at any time should seek advice of its counsel as to the proper application of this opinion letter at such time.
