On the terms and subject to the conditions hereof, either Borrower may from time to time borrow, prepay and reborrow Loans. SECTION 2.1.2. Lenders Not Permitted or Required To Make Loans. No Lender ----------------------------------------------- shall be permitted or required to make any Loan if, after giving effect thereto, the aggregate outstanding principal amount of all Loans to the Borrowers would exceed the Commitment Amount, or the aggregate principal amount of all Loans to the Borrowers of such Lender would exceed such Lender's Percentage of the Commitment Amount. The amount of each Lender's Percentage of the Commitment Amount on the date hereof is set forth below: -12- The Bank of Nova Scotia $50,000,000 Citibank, N.A. $50,000,000 The First National Bank of Chicago $50,000,000 SECTION 2.2. Optional Reduction of Commitment Amount. The Borrowers --------------------------------------- may, from time to time on any Business Day, voluntarily reduce the Commitment Amount; provided, however, that all such reductions shall require at least -------- ------- three Business Days' prior notice to the Administrative Agent and be permanent, and any partial reduction of the Commitment Amount shall be in a minimum amount of $1,000,000 and in an integral multiple of $1,000,000. SECTION 2.3. Borrowing Procedure. By delivering a Borrowing Request to ------------------- the Administrative Agent on or before 10:00 a.m., New York City time, on a Business Day, either Borrower may from time to time irrevocably request, on not less than three nor more than five Business Days' notice (or in the case of Base Rate Loans being requested, on the Business Day on which such Loans are to be made) that a Borrowing be made in a minimum amount of $1,000,000 and an integral multiple of $1,000,000, or in the unused amount of the Commitments. On the terms and subject to the conditions of this Agreement, each Borrowing shall be comprised of the same type of Loans, and shall be made on the Business Day, specified in such Borrowing Request. On or before 12:00 noon (New York City time) on such Business Day each Lender shall deposit with the Administrative Agent same day funds in an amount equal to such Lender's Percentage of the requested Borrowing. Such deposit will be made to an account which the Administrative Agent shall specify from time to time by notice to the Lenders. To the extent funds are received from the Lenders, the Administrative Agent shall make such funds available to such Borrower no later than 1:00 p.m. (New York City time) on the Business Day specified in the relevant Borrowing Request, by wire transfer to the accounts such Borrower shall have specified in its Borrowing Request. No Lender's obligation to make any Loan shall be affected by any other Lender's failure to make any Loan. SECTION 2.4. Continuation and Conversion Elections. By delivering a ------------------------------------- Continuation/Conversion Notice to the Administrative Agent on or before 10:00 a.m., New York City time, on a Business Day, the applicable Borrower may from time to time irrevocably elect, on not less than three nor more than five Business Days' notice (or to the extent Loans are being converted into Base Rate Loans, on the Business Day on which such conversion is to be made) that all, or any portion in an aggregate minimum amount of $1,000,000 and an integral multiple of $1,000,000, of any Loans to such Borrower be, in the case of Base Rate Loans to such -13- Borrower, converted into LIBO Rate Loans or, in the case of LIBO Rate Loans to such Borrower, be converted into a Base Rate Loan or continued as a LIBO Rate Loan (in the absence of delivery of a Continuation/Conversion Notice with respect to any LIBO Rate Loan at least three Business Days before the last day of the then current Interest Period with respect thereto, such LIBO Rate Loan shall, on such last day, automatically convert to a Base Rate Loan); provided, however, that (i) each such conversion or continuation shall - -------- ------- be pro-rated among the applicable outstanding Loans to such Borrower --------- of all Lenders, and (ii) no portion of the outstanding principal amount of any Loans may be continued as, or be converted into, LIBO Rate Loans when any Default has occurred and is continuing. SECTION 2.5. Funding. Each Lender may, if it so elects, fulfill ------- its obligation to make, continue or convert LIBO Rate Loans hereunder by causing one of its foreign branches or affiliates (or an international banking facility created by such Lender) to make or maintain such LIBO Rate Loan; provided, -------- however, that such LIBO Rate Loan shall nonetheless be deemed to have been made - ------- and to be held by such Lender, and the obligation of the applicable Borrower to repay such LIBO Rate Loan shall nevertheless be to such Lender for the account of such foreign branch, affiliate or international banking facility. In addition, each Borrower hereby consents and agrees that, for purposes of any determination to be made for purposes of Sections 4.1, 4.2, 4.3 or 4.4, ------------ --- --- --- it shall be conclusively assumed that each Lender elected to fund all LIBO Rate Loans to such Borrower by purchasing, as the case may be, Dollar certificates of deposit in the U.S. or Dollar deposits in its LIBOR Office's interbank eurodollar market. SECTION 2.6. Notes. Each Lender's Loans to a Borrower under its Commitment ----- shall be evidenced by a Note payable by such Borrower to the order of such Lender in a maximum principal amount equal to such Lender's Percentage of the Commitment Amount. Each Lender shall, and is hereby irrevocably authorized by each Borrower to, make (or cause to be made) appropriate notations on the grids attached to such Lender's Notes (or on any continuation of such grids), or otherwise to record in such Lender's internal records, appropriate notations, in each case evidencing, inter alia, the date of, the outstanding principal ----- ---- of, and the interest rate and Interest Period applicable to the Loans to such Borrower. The failure of any Lender to make any such notations shall not limit or otherwise affect any Obligations of the applicable Borrower. SECTION 2.7. Extension of Scheduled Commitment Termination Date. -------------------------------------------------- The Scheduled Commitment Termination Date is subject to extension pursuant to this Section 2.7. ----------- -14- SECTION 2.7.1. Request for Extension. Within 45 days prior to the then --------------------- Scheduled Commitment Termination Date (but no later than the thirtieth day prior to the then Scheduled Commitment Termination Date), the Borrowers may revocably request (in writing) the Lenders to extend the Scheduled Commitment Termination Date to the date that is exactly one year after the then Scheduled Commitment Termination Date; provided, however, that if such date is not a Business Day, -------- ------- the Borrowers shall request such extension to the Business Day immediately preceding the date that is exactly one year after the then Scheduled Commitment Termination Date. Such request shall be delivered to the Administrative Agent (such applicable requested date, the "Extension Date"). The Administrative Agent -------------- shall promptly notify the Lenders thereof. SECTION 2.7.2. Effectiveness of Extension. -------------------------- (a) Such extension shall become effective as of the then Scheduled Commitment Termination Date if all of the following conditions shall have been satisfied: (a) within 30 days of, but no later than the twentieth day prior to the then Scheduled Commitment Termination Date, Lenders with Commitments aggregating at least 66% of all Lenders' Commitments (the "Consenting Lenders") ------------------ shall have provided to the Administrative Agent their respective written agreement to such extension, (b) both before and after giving effect to such extension, on the Extension Date, (i) the representations and warranties set forth in Article VI shall be true and correct as if then made and (ii) no ---------- Default shall have then occurred and be continuing, and (c) the Borrowers shall have delivered to the Administrative Agent, a certificate, dated such Extension Date, of an Authorized Officer of each Borrower certifying that the conditions in clause (b) have been fully satisfied. If any Lender does not so notify the ---------- Administrative Agent of its decision within the period specified in Section ------- 2.7.2(a), such Lender shall be deemed not to have consented to such request of - -------- the Borrowers. (b) Each Lender that does not provide its consent to such extension (a "Non-Consenting Lender") hereby agrees that if, on or prior to the then - ---------------------- Scheduled Commitment Termination Date, any other Lender or other financial institution acceptable to the Borrowers and the Administrative Agent (the consent of the Administrative Agent not to be unreasonably withheld) offers to purchase such Non-Consenting Lender's Percentage of the Commitment Amount for a purchase price equal to the sum of all amounts then owing with respect to the Loans and all other amounts accrued for the account of such Non-Consenting Lender, such Non-Consenting Lender will assign, sell and transfer on the then Scheduled Commitment Termination Date all of its right, title, interest and obligations with respect to the foregoing to such other Lender or financial institution pursuant to the terms -15- of Section 10.11.1 and upon the effectiveness of such assignment, such Assignee --------------- Lender shall on such Scheduled Commitment Termination Date have a Commitment in the amount so assigned and be a Lender with a Commitment on and after the Extension Date. (c) If the Borrowers have requested an extension and there remains any Non- Consenting Lender which has not been replaced pursuant to Section 2.7.2(b), the ---------------- Borrowers, at least 15 days prior to the Scheduled Commitment Termination Date (without giving effect to the requested extension), may revoke the request for extension and the Scheduled Commitment Termination Date shall not be extended and the Stated Maturity Date shall remain unchanged for all Lenders. If no such notice of revocation is given by the Borrowers, on the date that would have been the Scheduled Commitment Termination Date had the Scheduled Commitment Termination Date not been extended pursuant to the terms of this Section, the outstanding Loans of any Non-Consenting Lender that were not purchased pursuant to Section 2.7.2(b) will mature and be due and payable on the then Scheduled ---------------- Commitment Termination Date, subject to the other terms hereof, and the Commitment of such Non-Consenting Lender will thereupon terminate on such Scheduled Commitment Termination Date. On such Scheduled Commitment Termination Date, the Commitment Amount will be automatically reduced by an amount equal to the product of (i) the sum of the Percentages of all Non-Consenting Lenders that were not purchased pursuant to Section 2.7.2(b), and (ii) the Commitment Amount ---------------- (whether used or unused) on such Scheduled Commitment Termination Date immediately prior to such calculation. (d) The Percentages of the Consenting Lenders and any assignees pursuant to Section 2.7.2(b) shall be adjusted accordingly by the Administrative Agent, - ---------------- based on such Lenders' pro rata share of the remaining Commitment Amount. --- ---- ARTICLE III REPAYMENTS, PREPAYMENTS, INTEREST AND FEES SECTION 3.1. Repayments and Prepayments . On the Stated Maturity Date, each -------------------------- Borrower shall repay in full the unpaid principal amount of each Loan that has been made to such Borrower. Prior thereto, (a) either Borrower may, from time to time on any Business Day, make a voluntary prepayment, in whole or in part, of the outstanding principal amount of any Loans made to such Borrower; provided, however, that (i) any such prepayment shall be made pro rata among - -------- ------- --- ---- such Loans of the same type and, if applicable, having the same Interest Period of all Lenders; (ii) no such prepayment of any LIBO Rate Loan may be made on any day other than the last day of the Interest Period for such Loan; -16- (iii) all such voluntary prepayments shall require at least three but no more than five Business Days' prior written notice (or in the case of prepayments of Base Rate Loans, same day's prior written notice) to the Administrative Agent; and (iv) all such voluntary partial prepayments shall be in an aggregate minimum amount of $500,000 (or in the case any partial prepayment of any LIBO Rate Loan, $1,000,000) and an integral multiple of $100,000; (b) each Borrower shall, on each date (other than on the Scheduled Commitment Termination Date) when any reduction in the Commitment Amount shall become effective, make a mandatory prepayment of each Loan that has been made to such Borrower in an aggregate amount for both Borrowers equal to the excess, if any, of the aggregate, outstanding principal amount of all Loans over the Commitment Amount as so reduced; and (c) each Borrower shall, immediately upon any acceleration of the maturity of any Loans pursuant to Section 8.2 or Section 8.3, repay each Loan ----------- ----------- that has been made to such Borrower, unless, pursuant to Section 8.3, only a ----------- portion of all Loans is so accelerated, in which case the Borrower shall repay the portion of the Loans made to such Borrower that have been so accelerated. Each prepayment of any Loans made pursuant to this Section shall be without premium or penalty, except as may be required by Section 4.4. No voluntary ----------- prepayment of principal of any Loans shall cause a reduction in the Commitment Amount. SECTION 3.2. Interest Provisions . Interest on the outstanding principal amount of Loans shall accrue and be payable in accordance with this Section 3.2. ----------- SECTION 3.2.1. Rates . Loans outstanding accrue interest at a rate per ----- annum: (a) on that portion maintained from time to time as a Base Rate Loan, equal to the Alternate Base Rate from time to time in effect; and (b) on that portion maintained as a LIBO Rate Loan, during each Interest Period applicable thereto, equal to the sum of the LIBO Rate (Reserve Adjusted) for such Interest Period plus a margin of 0.27 of 1% per annum. ---- The "LIBO Rate (Reserve Adjusted)" means, for any Interest Period, a rate ---------------------------- per annum (rounded upwards, if necessary, to the nearest 1/16 of 1%) determined pursuant to the following formula: LIBO Rate = LIBO Rate ------------------------------- (Reserve Adjusted) 1.00 - LIBOR Reserve Percentage The LIBO Rate (Reserve Adjusted) for any Interest Period for LIBO Rate Loans will be determined by the Administrative Agent on the basis of the LIBOR Reserve Percentage in effect on, and the applicable rates furnished to and received by the Administrative Agent from BNS, two Business Days before the first day of such Interest Period. -17- "LIBO Rate" means, relative to any Interest Period for LIBO Rate Loans, the --------- rate of interest equal to the average (rounded upwards, if necessary, to the nearest 1/16 of 1%) of the rates per annum at which Dollar deposits in immediately available funds are offered by BNS's LIBOR Office to prime banks in the London interbank market as at or about 11:00 a.m. London, England time, two Business Days prior to the beginning of such Interest Period for delivery on the first day of such Interest Period, and in an amount approximately equal to the amount of BNS's LIBO Rate Loan and for a period approximately equal to such Interest Period. "LIBOR Reserve Percentage" means, relative to any Interest Period for LIBO ------------------------ Rate Loans, the reserve percentage (expressed as a decimal) equal to the maximum aggregate reserve requirements (including all basic, emergency, supplemental, marginal and other reserves and taking into account any transitional adjustments or other scheduled changes in reserve requirements) specified under regulations issued from time to time by the F.R.S. Board and then applicable to assets or liabilities consisting of and including "Eurocurrency Liabilities", as defined from time to time in Regulation D of the F.R.S. Board, having a term approximately equal or comparable to such Interest Period. All LIBO Rate Loans shall bear interest from and including the first day of the applicable Interest Period to (but not including) the last day of such Interest Period at the interest rate determined as applicable to such LIBO Rate Loan. SECTION 3.2.2. Post-Maturity Rates . After the date any principal amount of ------------------- any Loan is due and payable (whether on the Stated Maturity Date, upon acceleration or otherwise), or after any other monetary Obligation of either Borrower shall have become due and payable, such Borrower shall pay, but only to the extent permitted by law, interest (after as well as before judgment) on such amounts at a rate per annum (in lieu of the rate per annum set forth in Section 3.2.1) equal to the Alternate Base Rate plus a margin of 2% per annum. - ------------- SECTION 3.2.3. Payment Dates . Interest accrued on each Loan shall be ------------- payable, without duplication: (a) on the Stated Maturity Date; (b) on the date of any payment or prepayment, in whole or in part, of principal outstanding on such Loan; (c) with respect to Base Rate Loans, on each Monthly Payment Date occurring after the date of the initial Borrowing hereunder; (d) with respect to LIBO Rate Loans, the last day of each applicable Interest Period; (e) with respect to any Base Rate Loans converted into LIBO Rate Loans on a day when interest would not otherwise have been payable pursuant to clause (c), ---------- on the date of such conversion; and (f) on that portion of any Loans the maturity of which is accelerated pursuant to Section 8.2 or Section 8.3, ----------- ----------- immediately upon such acceleration. Interest accrued on Loans or other -18- monetary Obligations arising under this Agreement or any other Loan Document after the date such amount is due and payable (whether on the Stated Maturity Date, upon acceleration or otherwise) shall be payable upon demand. SECTION 3.3. Fees . The Borrowers agree to pay the fees set forth in this ---- Section 3.3. - ----------- SECTION 3.3.1. Facility Fee . The Borrowers agree to pay to the ------------ Administrative Agent for the account of each Lender, for the period (including any portion thereof when its Commitment is suspended by reason of either Borrower's inability to satisfy any condition of Article V) commencing on (and --------- including) the Effective Date and continuing through the Commitment Termination Date, a non-refundable facility fee at the rate of .08 of 1% per annum on such Lender's Percentage of the Commitment Amount (regardless of usage). Such facility fees shall be payable by the Borrowers in arrears on each Quarterly Payment Date, commencing with the first such day following the Effective Date, and on the Commitment Termination Date. SECTION 3.3.2. Administration Fee . The Borrowers agree to pay to the ------------------ Administrative Agent for its own account, an administration fee agreed to in writing by the Administrative Agent and the Borrowers. ARTICLE IV CERTAIN, LIBO RATE AND OTHER PROVISIONS SECTION 4.1. LIBO Rate Lending Unlawful. If any Lender shall determine -------------------------- (which determination shall, upon notice thereof to the Borrowers and the Lenders, be conclusive and binding on the Borrowers) that the introduction of or any change in or in the interpretation of any law makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for such Lender to make, continue or maintain any Loan as, or to convert any Loan into, a LIBO Rate Loan, the obligations of all Lenders to make, continue, maintain or convert any such Loans shall, upon such determination, forthwith be suspended until such Lender shall notify the Administrative Agent that the circumstances causing such suspension no longer exist, and all LIBO Rate Loans shall automatically convert into Base Rate Loans at the end of the then current Interest Periods with respect thereto or sooner, if required by such law or assertion. SECTION 4.2. Deposits Unavailable . If the Administrative Agent shall have -------------------- determined that (a) Dollar deposits, as the case may be, in the relevant amount and for the relevant Interest Period are not available to BNS in its relevant market, or (b) by -19- reason of circumstances affecting BNS' relevant market, adequate means do not exist for ascertaining the interest rate applicable hereunder to LIBO Rate Loans, then, in either case, upon notice from the Administrative Agent to the Borrowers and the Lenders, the obligations of all Lenders under Section 2.3 and ----------- Section 2.4 to make or continue any Loans as, or to convert any Loans into, LIBO - ----------- Rate Loans shall forthwith be suspended until the Administrative Agent shall notify the Borrowers and the Lenders that the circumstances causing such suspension no longer exist. SECTION 4.3. Increased LIBO Rate Loan Costs, etc. Each Borrower agrees to ----------------------------------- reimburse each Lender for any increase in the cost to such Lender of, or any reduction in the amount of any sum receivable by such Lender in respect of, making, continuing or maintaining (or of its obligation to make, continue or maintain) any Loans to such Borrower as, or of converting (or of its obligation to convert) any such Loans into, LIBO Rate Loans. Such reimbursement obligation shall apply only to the extent such increased cost or reduced sum results from (a) any change in law or regulation (other than any such change which increases reserve costs, to the extent that such increase is included in the calculation of LIBO Rate (Reserve Adjusted) for the relevant Interest Periods) or in the interpretation of any law or regulation or (b) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law) promulgated after the date hereof. Such Lender shall promptly notify the Administrative Agent and the Borrowers in writing of the occurrence of any such event, such notice to state, in reasonable detail, the reasons therefor and the additional amount required fully to compensate such Lender for such increased cost or reduced amount. Such additional amounts shall be payable by the applicable Borrower directly to such Lender within five days of its receipt of such notice, and such notice shall, in the absence of manifest error, be conclusive and binding on the Borrowers. SECTION 4.4. Funding Losses . In the event any Lender shall incur any loss -------------- or expense (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to make, continue or maintain any portion of the principal amount of any Loan as, or to convert any portion of the principal amount of any Loan into, a LIBO Rate Loan) as a result of: (a) any conversion or repayment or prepayment of the principal amount of any LIBO Rate Loans on a date other than the scheduled last day of the Interest Period applicable thereto, whether pursuant to Section 3.1 or ----------- otherwise, (b) any Loans not being made as LIBO Rate Loans in accordance with the Borrowing Request therefor (other than as a result of the default by such Lender to make such Loans), or (c) any Loans not being continued as, or converted into, LIBO Rate Loans in accordance with the Continuation/ Conversion Notice therefor -20- (other than as a result of the default by such Lender to continue or convert such Loans), then, in each case, upon the written notice of such Lender to the relevant Borrower (with a copy to the Administrative Agent), such Borrower shall, within five days of its receipt thereof, pay directly to such Lender such amount as will (in the reasonable determination of such Lender) reimburse such Lender for such loss or expense. Such written notice (which shall include calculations in reasonable detail) shall, in the absence of manifest error, be conclusive and binding on such Borrower. SECTION 4.5. Increased Capital Costs . If any change in, or the ----------------------- introduction, adoption, effectiveness, interpretation, reinterpretation or phase-in after the date hereof of, any law or regulation, directive, guideline, decision or request (whether or not having the force of law) of any court, central bank, regulator or other governmental authority affects or would affect the amount of capital required or expected to be maintained by any Lender or any Person controlling such Lender, and such Lender determines (in its sole and absolute discretion) that the rate of return on its or such controlling Person's capital as a consequence of its Commitment or the Loans made by such Lender is reduced to a level below that which such Lender or such controlling Person could have achieved but for the occurrence of any such circumstance, then, in any such case upon notice from time to time by such Lender to the Borrowers, the Borrowers shall immediately pay directly to such Lender additional amounts sufficient to compensate such Lender or such controlling Person for such reduction in rate of return. A statement of such Lender as to any such additional amount or amounts (including calculations thereof in reasonable detail) shall, in the absence of manifest error, be conclusive and binding on the Borrowers. In determining such amount, such Lender may use any method of averaging and attribution that it (in its sole and absolute discretion) shall deem applicable. SECTION 4.6. Taxes . All payments by each Borrower of principal of, and ----- interest on, the Loans and all other amounts payable hereunder shall be made free and clear of and without deduction for any present or future income, excise, stamp or franchise taxes and other taxes, fees, duties, withholdings or other charges of any nature whatsoever imposed by any taxing authority, but excluding franchise taxes and taxes imposed on or measured by any Lender's net income or receipts (such non-excluded items being called "Taxes"). In the ----- event that any withholding or deduction from any payment to be made by either Borrower hereunder is required in respect of any Taxes pursuant to any applicable law, rule or regulation, then such Borrower will: (a) pay directly to the relevant authority the full amount required to be so withheld or deducted; (b) promptly forward to the Administrative Agent an official receipt or other -21- documentation satisfactory to the Administrative Agent evidencing such payment to such authority; and (c) pay to the Administrative Agent for the account of the Lenders such additional amount or amounts as is necessary to ensure that the net amount actually received by each Lender will equal the full amount such Lender would have received had no such withholding or deduction been required. Moreover, if any Taxes are directly asserted against the Administrative Agent or any Lender with respect to any payment received by the Administrative Agent or such Lender hereunder, the Administrative Agent or such Lender may pay such Taxes and the Borrowers will promptly pay such additional amounts (including any penalties, interest or expenses) as is necessary in order that the net amount received by such person after the payment of such Taxes (including any Taxes on such additional amount) shall equal the amount such person would have received had not such Taxes been asserted. If either Borrower fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent, for the account of the respective Lenders, the required receipts or other required documentary evidence, such Borrower shall indemnify the Lenders for any incremental Taxes, interest or penalties that may become payable by any Lender as a result of any such failure. For purposes of this Section 4.6, a distribution hereunder by the ----------- Administrative Agent or any Lender to or for the account of any Lender shall be deemed a payment by the applicable Borrower. Upon the request of either Borrower or the Administrative Agent, each Lender that is organized under the laws of a jurisdiction other than the United States shall, prior to the due date of any payments under the Notes, execute and deliver to such Borrower and the Administrative Agent, on or about the first scheduled payment date in each Fiscal Year, one or more (as such Borrower or the Administrative Agent may reasonably request) United States Internal Revenue Service Forms 4224 or Forms 1001 or such other forms or documents (or successor forms or documents), appropriately completed, as may be applicable to establish the extent, if any, to which a payment to such Lender is exempt from withholding or deduction of Taxes. SECTION 4.7. Payments, Computations, etc. Unless otherwise expressly --------------------------- provided, all payments by either Borrower pursuant to this Agreement, the Notes or any other Loan Document shall be made to the Administrative Agent for the pro --- rata account of the Lenders entitled to receive such payment. All such payments - ---- required to be made to the Administrative Agent shall be made, without setoff, deduction or counterclaim, not later than 11:00 a.m., New York City time, on the date due, in same day or immediately available funds, to such account as the Administrative Agent shall specify from time to time by notice to -22- the Borrowers. Funds received after that time shall be deemed to have been received by the Administrative Agent on the next succeeding Business Day. The Administrative Agent shall promptly remit in same day funds to each Lender its share, if any, of such payments received by the Administrative Agent for the account of such Lender. All interest and fees shall be computed on the basis of the actual number of days (including the first day but excluding the last day) occurring during the period for which such interest or fee is payable over a year comprised of 360 days (or, in the case of interest on a Base Rate Loan, 365 days or, if appropriate, 366 days). Whenever any payment to be made shall otherwise be due on a day which is not a Business Day, such payment shall (except as otherwise required by clause (c) of the definition of the term ---------- "Interest Period" with respect to LIBO Rate Loans) be made on the next --------------- succeeding Business Day and such extension of time shall be included in computing interest and fees, if any, in connection with such payment. SECTION 4.8. Sharing of Payments . If any Lender shall obtain any payment or ------------------- other recovery (whether voluntary, involuntary, by application of setoff or otherwise) on account of any Loan (other than pursuant to the terms of Sections -------- 4.3, 4.4, 4.5 and 4.6) in excess of its pro rata share of payments then or - --- --- --- --- --- ---- therewith obtained by all Lenders, such Lender shall purchase from the other Lenders such participations in Loans made by them as shall be necessary to cause such purchasing Lender to share the excess payment or other recovery ratably with each of them; provided, however, that if all or any portion of the excess -------- ------- payment or other recovery is thereafter recovered from such purchasing Lender, the purchase shall be rescinded and each Lender which has sold a participation to the purchasing Lender shall repay to the purchasing Lender the purchase price to the ratable extent of such recovery together with an amount equal to such selling Lender's ratable share (according to the proportion of (a) the amount of such selling Lender's required repayment to the purchasing Lender 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 may, to the fullest extent permitted by law, exercise all its rights of payment (including pursuant to Section 4.9) with respect to such participation as fully as if such Lender were - ----------- the direct creditor of the Borrowers in the amount of such participation. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a setoff to which this Section applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders entitled under this Section to share in the benefits of any recovery on such secured claim. -23- SECTION 4.9. Setoff . Each Lender shall, upon the occurrence of any Default ------ described in clauses (a) through (d) of Section 8.1.9 or any other Event of ----------- --- ------------- Default, and to the extent permitted by applicable law, have the right to appropriate and apply to the payment of the Obligations owing to it (whether or not then due) by either Borrower, any and all balances, credits, deposits, accounts or monies of such Borrower then or thereafter maintained with such Lender; provided, however, that any such appropriation and application shall -------- ------- be subject to the provisions of Section 4.8. Each Lender agrees promptly to ----------- notify the Borrowers and the Administrative Agent after any such setoff and application made by such Lender; provided, however, that the failure to give -------- ------- such notice shall not affect the validity of such setoff and application. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff under applicable law or otherwise) which such Lender may have. SECTION 4.10. Use of Proceeds . Each Borrower shall apply the proceeds of --------------- each Borrowing for general corporate purposes (including acquisitions of stock and assets). No proceeds of any Loan will be used to acquire any equity security of a class which is registered pursuant to Section 12 of the Securities Exchange Act of 1934, as amended, or to acquire or carry any "margin stock", as defined in F.R.S. Board Regulation U; provided, however, that Ambac Financial may use -------- ------- the proceeds of any Borrowing to purchase issued and outstanding shares of its common stock, par value of $.01 per share, for issuance to its employees and/or directors under its employee or director stock plans or to any of its Subsidiaries' employees under its employee stock plans or its Subsidiaries' employee stock plans.

If and to the extent that such Lender shall not have made such amount available to the Administrative Agent, such Lender and the Borrowers severally agree to repay the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date the Administrative Agent made such amount available to the applicable Borrower to the date such amount is repaid to the Administrative Agent, at the interest rate applicable at the time to Loans comprising such Borrowing. -38- SECTION 9.3. Exculpation. No Agent or any director, officer, employee ----------- or agent of any Agent shall be liable to any Lender for any action taken or omitted to be taken by it under any Loan Document, or in connection herewith or therewith, except for its own willful misconduct or gross negligence, nor responsible for any recitals or warranties herein or therein, nor for the effectiveness, enforceability, validity or due execution of any Loan Document, nor to make any inquiry respecting the performance by either Borrower of its obligations under any Loan Document. Any such inquiry which may be made by any Agent shall not obligate it to make any further inquiry or to take any action.

Each Lender also acknowledges that it will, independently of any Agent and each other Lender, and based on such other documents, information and investigations as it shall deem appropriate at any time, continue to make its own credit decisions as to exercising or not exercising from time to time any rights and privileges available to it under any Loan Document.

(d) With respect to submission to the jurisdiction of the federal courts of the United States, we note the limitation of 28 U.S.C. (S)1332 on federal court jurisdiction in cases where diversity of citizenship is lacking and we also note that such submission cannot supersede the court's discretion in determining whether to transfer an action from one federal court to another under 28 U.S.C.

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 Notes to which Ambac Assurance is a party are legal, valid, binding and enforceable under the law of the State of New York, the Credit Agreement and such Notes constitute the legal, valid and binding obligations of Ambac Assurance, and are enforceable against Ambac Assurance in accordance with their respective terms. -3- The opinions set forth above are subject to the following qualifications: (a) Our opinion in paragraph 5 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.

We have also assumed, without independent investigation, that (a) each Borrower (i) is a corporation duly organized and validly existing under the laws of the state of its incorporation and (ii) has full power and authority to enter into and perform its Obligations under each Loan Document to which it a party, (b) the execution, delivery and performance by each Borrower of the Loan Documents to which it is a party have been duly authorized by all necessary corporate action and do not violate or contravene any statutory law, rule or regulation applicable to such Borrower or any agreement, instrument or other document binding on or affecting such Borrower or any constituent document of such 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 Loan Documents to which it is a party, 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 the parties thereto and constitutes the legal, valid and binding obligation of the parties thereto (other than the Borrowers), and (e) the Credit Agreement and the Borrower Notes have been duly executed and delivered by each Borrower party thereto. As to factual matters, we have relied upon the representations and warranties contained in the Loan Documents and the certificates delivered in connection therewith. -2- Based upon the foregoing examination of documents and assumptions and upon such other investigation as we have deemed necessary, we are of the opinion that the Credit Agreement and the Borrower Notes constitute legal, valid and binding obligations of each Borrower that is a party thereto, enforceable against such Borrower in accordance with their respective terms. Our opinion set forth above is subject to the following qualifications: (a) Our opinion is limited to the laws of the State of New York and we do not express any opinion herein concerning any other law. (b) Our opinion is limited by (i) applicable bankruptcy, insolvency (including, without limitation all laws relating to fraudulent transfers), reorganization, moratorium and other similar laws affecting creditors' rights generally, and (ii) 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 at law or in equity). (c) We express no opinion as to the enforceability of the indemnification provisions set forth in Section 10.4 of the Credit Agreement to the extent enforcement thereof is contrary to public policy regarding the exculpation of criminal violations, intentional harm and acts of gross negligence or recklessness. (d) With respect to submission to the jurisdiction of the federal courts of the United States, we note the limitation of 28 U.S.C. (S)1332 on federal court jurisdiction in cases where diversity of citizenship is lacking and we also note that such submission cannot supersede the court's discretion in determining whether to transfer an action from one federal court to another under 28 U.S.C. (S)1404(a). We express no opinion with respect to waivers of objections that an action brought in a federal court of the United States was brought in an improper forum. (e) We express no opinion as to the effect of the law of any jurisdiction other than the State of New York wherein the Administrative Agent, or any Lender may be located or wherein enforcement of the Credit Agreement or the Notes may be sought which limits the rates of interest legally chargeable or collectible. -3- A copy of this opinion letter may be delivered by each of you to any Assignee Lender in connection with and at the time of any assignment and delegation by any of you as a Lender to such Assignee Lender of a portion of your Loans and Commitment in accordance with the provisions of the Credit Agreement, and such Assignee Lender may rely on the opinions expressed above with respect to the Credit Agreement as if this opinion letter were addressed and delivered to such Assignee Lender on the date hereof.
