(ii) The Borrowers agree for the benefit of the Agent and each Lender that, notwithstanding any provision of any Application, the obligations of the Borrowers under this Section 2.2(d) and each applicable Application shall be absolute, unconditional and irrevocable (subject to Section 2.2(c)) and shall be performed strictly in accordance with the terms of this Agreement and each applicable Application under all circumstances whatsoever (other than the defense of payment in accordance with this Agreement or a defense based on the gross negligence or willful misconduct of the Agent or any Lender), including, without limitation, the following circumstances (subject in all cases to the defense of payment in accordance with this Agreement or a defense based on the gross negligence or willful misconduct of the Agent or any Lender): (1) any lack of validity or enforceability of any of the L/C Documents; (2) any amendment or waiver of or any consent to depart from all or any of the provisions of any of the L/C Documents; (3) the existence of any claim, setoff, defense or other right the Borrowers may have at any time against a beneficiary of a Letter of Credit or an Agent Letter of Credit (or any Person for whom a beneficiary may be acting), the 42 Agent, any Lender or any other Person, whether in connection with this Agreement, another L/C Document or any unrelated transaction; (4) any statement or any other document presented under a Letter of Credit or an Agent Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; (5) payment by the Agent under a Letter of Credit or an Agent Letter of Credit against presentation to the Agent of a draft or certificate that does not comply with the terms of the Letter of Credit or the Agent letter of Credit, provided that the Agent's determination that documents presented under the Letter of Credit or the Agent Letter of Credit comply with the terms thereof did not constitute gross negligence or willful misconduct of the Agent; or (6) any other act or omission to act or delay of any kind by the Agent, any Lender or any other Person or any other event or circumstance whatsoever that might, but for the provisions of this Section 2.2(d), constitute a legal or equitable discharge of the Borrowers' obligations hereunder or under any L/C Document, provided that such act or omission of the Agent did not constitute gross negligence or willful misconduct of the Agent. (d) The Participating Interests. Each Lender severally and not jointly --------------------------- agrees to purchase from the Agent, and the Agent hereby agrees to sell to each Lender, an undivided percentage participating interest, to the extent of its Percentage, in each Letter of Credit issued by, and Reimbursement Obligation owed to, the Agent in connection with a Letter of Credit. Upon any failure by the Borrowers to pay any Reimbursement Obligation in connection with a Letter of Credit at the time required in Sections 2.2(d) and 2.5(b), or if the Agent is required at any time to return to the Borrowers or to a trustee, receiver, liquidator, custodian or other Person any portion of any payment by the Borrowers of any Reimbursement Obligation in connection with a Letter of Credit, the Agent shall promptly give notice of same to each Lender, and the Agent shall have the right to require each Lender to fund its participation in such Reimbursement Obligation. Each Lender (except the Agent to the extent it is also a Lender) shall pay to the Agent an amount equal to each Lender's Percentage of such unpaid or recaptured Reimbursement Obligation not later than the Business Day it receives notice from the Agent to such effect, if such notice is received before 2:00 p.m., or not later than the following Business Day if such notice is received after such time. If a Lender fails to pay timely such amount to the Agent, it shall also pay to the Agent interest on such amount accrued from the date payment of such amount was made by the Agent to the date of such payment by the Lender at a rate per annum equal to the Base Rate in effect for each such day, and only after such payment shall such Lender be entitled to receive its Percentage of each payment received on the relevant Reimbursement Obligation and of interest paid thereon. If any such Lender fails to pay such amount to the Agent, any payments made by the Borrowers with respect to the relevant Reimbursement Obligation shall first be applied by the Agent to the unfunded participation in such Reimbursement Obligation before any other Lenders receive any payments or proceeds. The several obligations of the Lenders to the Agent under this Section 2.2(d) shall be absolute, 43 irrevocable and unconditional under any and all circumstances whatsoever and shall not be subject to any setoff, counterclaim or defense to payment any Lender may have or have had against the Borrowers, the Agent, any other Lender or any other Person whatsoever including, but not limited to, any defense based on the failure of the demand for payment under the Letter of Credit to conform to the terms of such Letter of Credit or the legality, validity, regularity or enforceability of such Letter of Credit and INCLUDING, BUT NOT LIMITED TO, THOSE RESULTING FROM THE AGENT'S OWN SIMPLE OR CONTRIBUTORY NEGLIGENCE. Without limiting the generality of the foregoing, such obligations shall not be affected by any Default or Event of Default or by any subsequent reduction or termination of any Commitment of a Lender, and each payment by a Lender under Section 2.2 shall be made without any offset, abatement, withholding or reduction whatsoever. Section 2.3. Borrowings of Term Loans. Subject to the terms and ------------------------ conditions hereof, each Lender severally and not jointly agrees to make one or more loans (each a "Term Loan") to the Borrowers from time to time before the Term Commitment Termination Date in an aggregate amount not to exceed at any time outstanding an amount equal to its Percentage of the Term Credit Commitment Amount (for each Lender, its "Term Credit Commitment"), subject to any reductions thereof pursuant to the terms of this Agreement. The Term Loans shall be made ratably from the Lenders in proportion to their respective Percentages. No Lender shall be permitted or required to make any Term Loan if, after giving effect thereto, the aggregate principal amount of all Term Loans (i) of all Lenders would exceed the Term Credit Commitment Amount, or (ii) of such Lender would exceed the Percentage of such Lender of the Term Credit Commitment Amount. Any portion of the Term Credit Commitments not borrowed on or before the Term Commitment Termination Date shall terminate and not be available for borrowing. Funding of the Term Loans shall be in Dollars. Section 2.4. Types of Loans and Minimum Borrowing Amounts. Borrowings of -------------------------------------------- both Revolving Loans, Term Loans and Agent Loans may be outstanding as either Base Rate Loans or Eurodollar Loans, as selected by the Borrowers pursuant to Section 2.5; provided, however, that any Revolving Loans funded in Pounds or Canadian Dollars may only be outstanding as Eurodollar Loans. All Borrowings advanced on the Initial Borrowing Date shall be advanced in Dollars and as Base Rate Loans. Each Borrowing of Base Rate Loans shall be in an amount of not less than $300,000 (except with respect to Agent Loans) and each Borrowing of Eurodollar Loans shall be in an amount of not less than $3,000,000 (except with respect to Agent Loans) (or the equivalent thereof in Pounds or Canadian Dollars as applicable and as determined in accordance with Section 10.19). Each Borrowing of an Agent Loan as a Base Rate Loan shall be in an amount of less than $300,000, and each Borrowing of an Agent Loan as a Eurodollar Loan shall be in an amount of less than $3,000,000. Section 2.5. Manner of Borrowing. (a) Notice to the Agent. The Borrowers ------------------- ------------------- shall give notice to the Agent by no later than 12:00 p.m. (i) at least three (3) Business Days before the date on which the Borrowers request the Lenders to advance a Borrowing of Eurodollar Loans to be funded in Dollars and at least four (4) Business Days before the date on which the Borrowers request the Lenders to advance a Borrowing of Eurodollar Loans in Canadian Dollars or Pounds, and (ii) on the date the Borrowers request the Lenders to advance a Borrowing of Base Rate Loans pursuant to a duly executed Borrowing Request in the form of Exhibit 2.5 (each 44 a "Borrowing Request"). The Borrowers may select multiple Interest Periods for the Term Loans, for the Agent Loans and for the Revolving Loans constituting any particular Borrowing, provided that at no time shall the number of different Interest Periods for outstanding Eurodollar Loans exceed eight (8) (it being understood for such purposes that (x) Interest Periods of the same duration, but commencing on different dates, shall be counted as different Interest Periods and (y) all Interest Periods commencing on the same date and of the same duration shall be counted as different Interest Periods if Revolving Loans, Agent Loans and Term Loans are involved. The Loans included in each Borrowing shall bear interest initially at the type of rate specified in such new Borrowing Request with respect to such Borrowing. Thereafter, the Borrowers may from time to time elect to change or continue the type of interest rate borne by each Borrowing or, subject to Section 2.4's minimum amount requirement for each outstanding Borrowing, a portion thereof, as follows: (i) if such Borrowing is of Eurodollar Loans, the Borrowers may continue part or all of such Borrowing as Eurodollar Loans for an Interest Period specified by the Borrowers or convert part or all of such Borrowing into Base Rate Loans on the last day of the Interest Period applicable thereto, or the Borrowers may earlier convert part or all of such Borrowing into Base Rate Loans so long as they pay the breakage fees and funding losses provided in Section 2.13, and (ii) if such Borrowing is of Base Rate Loans, the Borrowers may convert all or part of such Borrowing into Eurodollar Loans for an Interest Period specified by the Borrowers on any Business Day. Notices of the continuation of a Borrowing of Eurodollar Loans for an additional Interest Period or of the conversion of part or all of a Borrowing of Eurodollar Loans into Base Rate Loans or of Base Rate Loans into Eurodollar Loans must be given by no later than 12:00 p.m. at least three (3) Business Days with respect to Eurodollar Loans funded in Dollars and four (4) Business Days before such Borrowing with respect to Eurodollar Loans funded in Canadian Dollars or Pounds, before the date of the requested continuation or conversion. The Borrowers shall give such notices concerning the advance, continuation, or conversion of a Borrowing by telephone or facsimile (which notice shall be irrevocable once given and, if by telephone, shall be promptly confirmed in writing) pursuant to a Borrowing Request which shall specify the date of the requested advance, continuation or conversion (which shall be a Business Day), the amount and currency of the requested Borrowing, whether any portion the requested Borrowing shall be used for funding any acquisition pursuant to the provisions of Sections 5.5 and 6.13, the Credit under which the Borrowing is to be advanced, continued, or converted, the type of Loans to comprise such new, continued or converted Borrowing and, if such Borrowing is to be comprised of Eurodollar Loans, the Interest Period applicable thereto. The Borrowers agree that the Agent may rely on any such telephonic or facsimile notice given by any person it in good faith believes is an authorized representative of the Borrowers without the necessity of independent investigation and that, if any such notice by telephone conflicts with any written confirmation, such telephonic notice shall govern if the Agent has acted in reliance thereon. The Agent shall give prompt telephonic, telex or facsimile notice to each Lender of any notice received pursuant to Section 2.5(a) relating to a Borrowing under such Credit. (b) Borrowers' Failure to Notify. If the Borrowers fail to give notice ---------------------------- pursuant to Section 2.5(a) of (i) the continuation or conversion of any outstanding principal amount of a Borrowing of Eurodollar Loans or of (ii) a Borrowing of Loans to pay outstanding Reimbursement Obligations, and has not notified the Agent by 12:00 p.m. at least three (3) Business Days before the last day of the Interest Period for such Borrowing of Eurodollar Loans 45 funded in Dollars or at least four (4) Business Days before the last day of the Interest Period for such Borrowing of Eurodollar Loans funded in Canadian Dollars or Pounds or the day such Reimbursement Obligation becomes due that it intends to repay such Borrowing or such Reimbursement Obligation with funds not borrowed hereunder, the Borrowers shall be deemed to have requested, as applicable, (x) the continuation of such Borrowing as a Eurodollar Loan with an Interest Period of one (1) month, (y) the advance of a new Borrowing of Base Rate Loans under the Revolving Credit (after converting, if necessary, the Reimbursement Obligation into Dollars as provided in Section 10.19) on such day in the amount of the Reimbursement Obligation then due, or (z) with respect to Agent Loans or Agent Letters of Credit, the advance of a new Borrowing of an Agent Loan as a Base Rate Loan under the Agent Swing Line on such day in the amount of the Agent Reimbursement Obligation then due, which Borrowing shall be deemed to have been funded on such day to pay the Reimbursement Obligation or Agent Reimbursement Obligation, as the case may be, then due, in each case so long as no Default or Event of Default shall have occurred and be continuing or would occur as a result of such Borrowing but otherwise disregarding the conditions to Borrowing set forth in Section 4.2. Upon the occurrence and during the continuance of any Event of Default, (i) each Eurodollar Loan will automatically, on the last day of the then existing Interest Period therefor, convert into a Base Rate Loan and (ii) the obligation of the Lenders to fund loans in Canadian Dollars or Pounds and make, continue or convert Loans into Eurodollar Loans shall be suspended. (c) Disbursement of Loans. Not later than 12:00 p.m. on the date of any --------------------- requested advance of a new Borrowing of Loans, each Lender under the relevant Credit, subject to all other provisions hereof, shall make available its Loan comprising its ratable share of such Borrowing in funds immediately available in New York, New York for the benefit of the Agent and according to the disbursement instructions of the Agent. The Agent shall make the proceeds of each such Borrowing available in immediately available funds to the Borrowers on such date. No Lender shall be responsible to the Borrowers for any failure by another Lender to fund its portion of a Borrowing, and no such failure by a Lender shall relieve any other Lender from its obligation, if any, to fund its portion of a Borrowing. (d) Agent Reliance on Lender Funding. Unless the Agent shall have been -------------------------------- notified by a Lender before the date on which such Lender is scheduled to make payment to the Agent of the proceeds of a Loan (which notice shall be effective upon receipt) that such Lender does not intend to make such payment, the Agent may assume that such Lender has made such payment when due and in reliance upon such assumption may (but shall not be required to) make available to the Borrowers the proceeds of the Loan to be made by such Lender and, if any Lender has not in fact made such payment to the Agent, such Lender shall, on demand, pay to the Agent the amount made available to the Borrowers attributable to such Lender together with interest thereon for each day during the period commencing on the date such amount was made available to the Borrowers and ending on (but excluding) the date such Lender pays such amount to the Agent at a rate per annum equal to the interest rate attributable to the relevant Loan. If such corresponding amount is not in fact made available to the Agent by such Lender on the date of the Borrowing, the Agent shall be entitled to recover such corresponding amount on demand from such Lender, together with interest at its cost of funds. If such amount is not received from such Lender by the Agent immediately upon demand, the Borrowers will, on demand, 46 repay to the Agent the proceeds of the Loan attributable to such Lender with interest thereon at a rate per annum equal to the interest rate applicable to the relevant Loan. Section 2.6. Interest Periods. As provided in Section 2.5(a), at the time ---------------- of each request for the advance or continuation of, or conversion into, a Borrowing of Eurodollar Loans, the Borrowers shall select an Interest Period applicable to such Loans from among the available options subject to the limitations in Section 2.5(a); provided, however, that: (i) the Borrowers may not select an Interest Period for a Borrowing of Revolving Loans or Agent Loans that extend beyond the applicable Maturity Date for Revolving Loans or Agent Loans, as the case may be; (ii) the Borrowers may not select an Interest Period for a Borrowing of Term Loans that would end after an Amortization Date if, as a result, the aggregate principal amount of Term Loans scheduled to be outstanding with Interest Periods ending after such Amortization Date would exceed the principal amount of Term Loans permitted to be outstanding after such Amortization Date; (iii) whenever the last day of any Interest Period would otherwise be a day that is not a Business Day, the last day of such Interest Period shall either be (i) extended to the next succeeding Business Day, or (ii) reduced to the immediately preceding Business Day if the next succeeding Business Day is in the next calendar month; and (iv) for purposes of determining an Interest Period, a month means a period starting on one day in a calendar month and ending on the numerically corresponding day in the next calendar month; provided, however, that if there is no such numerically corresponding day in the month in which an Interest Period is to end or if an Interest Period begins on the last Business Day of a calendar month, then such Interest Period shall end on the last Business Day of the calendar month in which such Interest Period is to end. Section 2.7. Maturity of Loans. (a) Revolving Loans. Each Revolving Loan ----------------- --------------- shall mature and become due and payable by the Borrowers on the applicable Maturity Date for Revolving Loans. Each Agent Loan shall mature and become due and payable by the Borrowers on the applicable Maturity Date for the Agent Loans. At least ninety (90) days prior to the fourth anniversary of the Effective Date, the Borrowers may provide the Agent with a written notice requesting the Lenders to extend the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans for an additional one (1) year period. If the Borrowers shall request the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans to be extended for an additional one (1) year period, then the Agent shall promptly notify each Lender of such request and each Lender shall notify the Agent, not fewer than thirty (30) days prior to the Revolving Commitment Termination Date and the Maturity Date for the Revolving Loans, whether, in the exercise of its sole discretion, it will extend the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans for an additional one (1) year period and, in the event such Lender commits to such extensions but only at a lower Commitment (each such Lender, a "Reduced Declining Lender"), such notice will specify a 47 proposed Total Commitment Amount and its proposed Designated Commitment. Any Lender which shall not timely notify the Agent whether it will extend the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans shall be deemed to not have agreed to such extensions. No Lender shall have any obligation whatsoever to extend the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans. (b) Extension of Maturity Date for Revolving Loans. If the Lenders notify ---------------------------------------------- the Agent pursuant to Section 2.7(a) of their agreement to extend the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans (each such Lender, an "Accepting Lender"), then the Agent shall so notify each Lender and the Borrowers, and such extensions shall be effective without other or further action by any party hereto for such additional one-year period. If any one or more of the Lenders shall notify or be deemed to have notified the Agent that it will not extend the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans at the then current Total Commitment Amount (each such Lender, a "Declining Lender"), then (i) the Agent shall promptly so notify the Borrowers and the Accepting Lenders; (ii) the Accepting Lenders shall, upon the Borrowers' election to extend the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans in accordance with clause (w), (x) or (y) below, extend the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans; and (iii) the Borrowers shall, pursuant to a notice (an "Election Notice") delivered to the Agent, the Accepting Lenders and the Declining Lenders not fewer than ten (10) Business Days prior to the Election Effective Date, either: (w) elect to extend the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans with respect to the Accepting Lenders and direct the Declining Lenders to terminate their Commitments, which termination shall become effective on the Election Effective Date. On such Election Effective Date (A) the Borrowers shall deliver notice of the effectiveness of such termination to the Declining Lenders and to the Agent, (B) the Borrowers shall pay in full in immediately available funds all Obligations of the Borrowers hereunder including, without limitation, all breakage fees provided for in Section 2.13 and all other costs, fees and expenses payable and owing to each such Declining Lender hereunder and otherwise cause the Declining Lenders no longer to have any liability or obligation under or with respect to any Letter of Credit issued hereunder, whether by termination, cancellation, expiration or amendment of all such Letters of Credit, replacement of such Letters of Credit or otherwise, and upon the events described in this clause (x), the Declining Lenders shall cease to be a "Lender" hereunder for all purposes, other than for purposes of Sections 2.13, 3.3, 8.3 and 10.13 and shall cease to have any obligations or any Commitment hereunder, other than to the Agent pursuant to Section 9.6 and to the Borrowers pursuant to Section 10.15, and the Agent shall promptly notify the Accepting Lenders and the Borrowers of the new Total Commitment Amount and the respective Percentages of each Accepting Lender. So long as (A) no Default or Event of Default has occurred and is continuing, and (B) the aggregate principal amount of the Revolving Loans of all Lenders and other Revolving Obligations outstanding of the Borrowers do not exceed the new Revolving Credit Commitment Amount, the Agent shall reallocate the Percentage of each Lender in the Letters of Credit issued hereunder at such time; or 48 (x) elect to extend the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans with respect to (x) the Accepting Lenders and (y) all of the Reduced Declining Lenders and direct any Declining Lenders to terminate their respective Commitments, which termination shall become effective on the Election Effective Date; provided that effective on the Election Effective Date, the Total Commitment Amount shall be reduced to the lower of (A) the lowest Total Commitment Amount proposed by a Reduced Declining Lender in the notice provided pursuant to Section 2.7(a) and (B) the aggregate of the Designated Commitments of all Accepting Lenders and all Reduced Declining Lenders and each remaining Lender's Percentage shall be adjusted to equal the quotient of (1) such Lender's Designated Commitment divided by (2) the reduced Total Commitment Amount. On such Election Effective Date, the Borrowers shall pay in full, in immediately available funds, all Obligations of the Borrowers hereunder including, without limitation, all breakage fees provided for in Section 2.13 and all other costs, fees and expenses payable to each Declining Lender hereunder and otherwise cause such Declining Lenders no longer to have any liability or obligation under or with respect to any Letter of Credit issued hereunder, whether by termination, cancellation, expiration or amendment of all such Letters of Credit, replacement of such Letters of Credit or otherwise and pay to the Reduced Declining Lenders and the Accepting Lenders such amounts as are necessary to cause the amounts owing to the Reduced Declining Lenders and the Accepting Lenders to reflect their reduced Commitments and their new Percentages thereafter; each Declining Lender as is terminating its respective Commitments shall cease to be a "Lender" hereunder for all purposes, other than for purposes of Sections 2.13, 3.3, 8.3 and 10.13 and shall cease to have any obligations or any Commitment hereunder, other than to the Agent pursuant to Section 9.6 and to the Borrowers pursuant to Section 10.15; and the Agent shall promptly notify the Accepting Lenders, the Reduced Declining Lenders and the Borrowers of the new Total Commitment Amount and the respective Percentages of each Lender. So long as (A) no Default or Event of Default has occurred and is continuing, and (B) the aggregate principal amount of the Revolving Loans of all Lenders and other Revolving Obligations outstanding of the Borrowers do not exceed the new Revolving Credit Commitment Amount, the Agent shall reallocate the Percentage of each Lender in the Letters of Credit issued hereunder at such time; or (y) elect to extend the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans with respect to the Accepting Lenders and the Reduced Declining Lenders, and to replace one or more of the Reduced Declining Lenders or the Declining Lenders effective on the Election Effective Date, with one or more banks reasonably acceptable to the Agent; provided that (A) if one or more Lenders shall be a Reduced Declining Lender that is not being replaced, then effective on the Election Effective Date, the Total Commitment Amount shall be reduced to the lower of (1) the lowest Total Commitment Amount proposed by a Reduced Declining Lender that is not being replaced and (2) the aggregate of the Designated Commitments of all Accepting Lenders and the Reduced Declining Lenders that are not being replaced; (B) on such date the Borrowers shall pay in immediately available funds to such Reduced Declining Lenders that are not being replaced and to the Accepting Lenders such amounts as are necessary to cause amounts owing to such Reduced Declining Lenders and the 49 Accepting Lenders to reflect their reduced Commitments and their new Percentages thereafter; (C) the replacement banks shall purchase the Note or Notes of the Declining Lender or Lenders being replaced and such Declining Lender's or Lenders' rights hereunder, without recourse or expense to, or warranty by, such Declining Lender or Lenders being replaced for a purchase price equal to the sum of the aggregate outstanding principal amount of the Note or Notes payable to the Declining Lender or Lenders, such Declining Lender's or Lenders' respective Percentage of any outstanding Reimbursement Obligations, any accrued but unpaid interest on such Note or Notes and such Reimbursement Obligations, and any accrued but unpaid fees in respect of such Declining Lender's or Lenders' outstanding Borrowings and percentage of Commitments hereunder, and such replacement banks shall assume such Declining Lender's or Lenders' respective Percentage with respect to any outstanding Letters of Credit hereunder; (D) all Obligations of the Borrowers owing under or in connection with this Agreement and the Credit Documents to the Declining Lender or Lenders being replaced (including, without limitation, all breakage fees provided for in Section 2.13 and all other costs, fees and expenses payable to each Declining Lender hereunder) shall be paid by the Borrowers in full in immediately available funds to such Declining Lender or Lenders being replaced concurrently with such replacement; and (E) upon the payment of such amounts, the replacement banks shall each constitute a "Lender" hereunder and the Declining Lenders or Lenders being replaced shall no longer constitute a "Lender" hereunder (other than for purposes of Sections 2.13, 3.3, 8.3 and 10.13) and shall no longer have any obligations hereunder, other than to the Agent pursuant to Section 9.6 and to the Borrowers pursuant to Section 10.15. So long as (A) no Default or Event of Default has occurred and is continuing, and (B) the aggregate principal amount of the Revolving Loans of all Lenders and other Revolving Obligations outstanding of the Borrowers do not exceed the new Revolving Credit Commitment Amount, the Agent shall reallocate the Percentage of each Lender in the Letters of Credit issued hereunder at such time; or (z) elect to revoke and cancel the written notice requesting the Lenders to extend the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans for an additional one (1) year period by giving written notice of such revocation and cancellation to the Agent (which shall promptly notify the Lenders thereof) at least ten (10) Business Days prior to the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans. If the Borrowers fail to provide an Election Notice on or prior to the tenth (10th) Business Day preceding the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans, the Borrowers shall be deemed to have revoked and cancelled its written notice requesting the Lenders to extend the Revolving Commitment Termination Date and the Maturity Date for Revolving Loans for an additional one (1) year period. Upon the election by the Borrowers described in Section 2.7(c), the Borrowers shall give prompt notice to the Agent of such election. (c) Term Loans. The Borrowers shall repay a portion of the Term Loans on ---------- the last Business Day of each calendar quarter (except with respect to the last payment date which day 50 shall be the applicable Maturity Date for Term Loans), commencing on September 30, 1997 ("Amortization Date"), in the amount equal to the percentage set forth opposite such date on Schedule 2.7 multiplied by the outstanding amount of the Term Loan as of June 30, 1997 (or, if less, the aggregate principal amount of Term Loans then outstanding). The Borrowers shall repay in full the unpaid principal amount of the Term Loans on the applicable Maturity Date for Term Loans. Section 2.8. Applicable Interest Rates. (a) Base Rate Loans. Each Base ------------------------- --------------- Rate Loan shall bear interest (computed on the basis of a 360-day year and actual days elapsed excluding the date of repayment) on the unpaid principal amount thereof from the date such Loan is made until maturity (whether by acceleration or otherwise) or conversion to a Eurodollar Loan, at a rate per annum equal to the lesser of (i) the Highest Lawful Rate, or (ii) the Base Rate from time to time in effect, payable on each Interest Payment Date for such Loan and at maturity (whether by acceleration or otherwise). (b) Eurodollar Loans. Each Eurodollar Loan shall bear interest (computed ---------------- on the basis of a 360-day year and actual days elapsed, except with respect to Eurodollar Loans funded in Pounds, in which case interest will be computed on the basis of a 365-day year and actual days elapsed, in each case excluding the date of repayment) on the unpaid principal amount thereof from the date such Loan is made until maturity (whether by acceleration or otherwise) or conversion to a Base Rate Loan at a rate per annum equal to the lesser of (i) the Highest Lawful Rate, or (ii) the sum of Adjusted LIBOR plus the Applicable Margin, payable on each Interest Payment Date for such Loan and at maturity (whether by acceleration or otherwise) or conversion to a Base Rate Loan. (c) Rate Determinations. The Agent shall determine each interest rate ------------------- applicable to the Loans and Reimbursement Obligations hereunder and such determination shall be conclusive and binding except in the case of the Agent's manifest error or willful misconduct. The Agent shall give prompt telephonic, telex or facsimile notice to the Borrowers and each Lender of the interest rate applicable to each Loan or Reimbursement Obligation (but, if such notice is given by telephone, the Agent shall confirm such rate in writing) promptly after the Agent has made such determination. Section 2.9. Default Rate. If any payment of principal on any Loan is not ------------ made when due after the expiration of the grace period therefor provided in Section 7.1(a) (whether by acceleration or otherwise), such Loan shall bear interest (computed on the basis of a year of 360, 365 or 366 days, as applicable, and actual days elapsed) from the date such payment was due until such principal then due is paid in full, payable on demand, at a rate per annum equal to: (a) for any Base Rate Loan the lesser of (i) the Highest Lawful Rate, or (ii) the sum of two percent (2%) per annum plus the Base Rate from time to time in effect (but not less than the Base Rate in effect at maturity); (b) for any Eurodollar Loan the lesser of (i) the Highest Lawful Rate, or (ii) the sum of two percent (2%) per annum plus the rate of interest in effect thereon at the time of such default until the end of the Interest Period for such Loan and, thereafter, at a rate per annum 51 equal to the sum of two percent (2%) per annum plus the Base Rate from time to time in effect (but not less than the Base Rate in effect at maturity); and (c) for any unpaid Reimbursement Obligations with respect to Letters of Credit or Agent Letters of Credit, the lesser of (i) the Highest Lawful Rate, or (ii) the sum of two percent (2%) per annum plus the Base Rate from time to time in effect (but not less than the Base Rate in effect at maturity). It is the intention of the Agent and the Lenders to conform strictly to usury laws applicable to them. Accordingly, if the transactions contemplated hereby or the Loans would be usurious as to any of the Lenders or ABN AMRO under laws applicable to it (including the laws of the United States of America and the State of New York or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement, the Notes or any other Credit Document), then, in that event, notwithstanding anything to the contrary in this Agreement, the Notes or any other Credit Document, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under laws applicable to the Lender or ABN AMRO that is contracted for, taken, reserved, charged or received by such Lender under this Agreement, the Notes or any other Credit Document or otherwise shall under no circumstances exceed the Highest Lawful Rate, and any excess shall be credited by such Lender on the principal amount of the Notes or to the Reimbursement Obligations (or, if the principal amount of the Notes and all Reimbursement Obligations shall have been paid in full, refunded by such Lender or ABN AMRO to the Borrowers); and (ii) in the event that the maturity of the Notes is accelerated by reason of an election of the holder or holders thereof resulting from any Event of Default hereunder or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under laws applicable to the Lender may never include more than the Highest Lawful Rate, and excess interest, if any, provided for in this Agreement, the Notes, any other Credit Document or otherwise shall be automatically canceled by such Lender or ABN AMRO as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by the Lender or ABN AMRO on the principal amount of the Notes or to the Reimbursement Obligations (or if the principal amount of the Notes and all Reimbursement Obligations shall have been paid in full, refunded by such Lender or ABN AMRO to the Borrowers). To the extent that Article 5069-1.04 of the Texas Revised Civil Statutes is relevant to ABN AMRO or the Lenders for the purpose of determining the Highest Lawful Rate, ABN AMRO and the Lenders hereby elect to determine the applicable rate ceiling under such Article by the indicated (weekly) rate ceiling from time to time in effect, subject to their right subsequently to change such method in accordance with applicable law. In the event the Loans and all Reimbursement Obligations are paid in full by the Borrowers prior to the full stated term of the Loans and the interest received for the actual period of the existence of the Loans exceeds the Highest Lawful Rate, the Lenders or ABN AMRO shall refund to the Borrowers the amount of the excess or shall credit the amount of the excess against amounts owing under the Loans and none of ABN AMRO or the Lenders shall be subject to any of the penalties provided by law for contracting for, taking, reserving, charging or receiving interest in excess of the Highest Lawful Rate.

If the aggregate principal amount of outstanding Agent Loans and Agent L/C Obligations shall at any time for any reason exceed the Agent Commitment Amount then in effect, the Borrowers shall, immediately and without notice or demand, pay the amount of such excess to the Agent for the benefit of the Agent, as a prepayment of the Agent Loans and, if all Agent Loans have been paid, a pre-funding of Agent Letters of Credit. Any mandatory prepayment of Loans pursuant hereto shall not be limited by the notice provision for prepayments set forth in Section 2.10, but immediately upon determining the need to make any such prepayment, the Borrowers shall notify the Agent of such required prepayment. Each such prepayment shall be accompanied by a payment of all accrued and unpaid interest on the Loans prepaid and any applicable breakage fees and funding losses pursuant to Section 2.13.

Amounts prepaid under the Term Loans may not be reborrowed. After the Term Loans have been paid in full, the Borrowers shall not be required to make any further mandatory prepayments pursuant to this Section 2.11(b). (c) Beginning on September 30, 1997, and on each Amortization Date thereafter, if Holdings has a Total Funded Debt to Total Capital Ratio which is greater than 35% for the preceding fiscal quarter, the Borrowers shall make a mandatory prepayment of the Term Loans (which mandatory prepayment shall be applied in inverse order of maturity to the last four (4) scheduled Term Loan payments), in an amount equal to 50% of Excess Cash Flow of Holdings and its Subsidiaries for such preceding fiscal quarter.

Such record, whether shown on the books and records of a holder of a Note or on a schedule to its Note, shall be prima facie evidence as to all such matters; provided, however, that the failure of any holder to record any of the foregoing or any error in any such record shall not limit or otherwise affect the obligation of the Borrowers to repay all Loans outstanding to it hereunder together with accrued interest thereon. At the request of any holder of a Note and upon such holder tendering to the Borrowers the Note to be replaced, the Borrowers shall furnish a new Note to such holder to replace any outstanding Note and at such time the first notation appearing on the schedule on the reverse side of, or attached to, such new Note shall set forth the aggregate unpaid principal amount of all Loans, if any, then outstanding thereon. 54 Section 2.13.

If any Lender makes such a claim for compensation, it shall provide to the Borrowers a certificate executed by an officer of such Lender setting forth the amount of such loss, cost or expense in reasonable detail (including an explanation of the basis for and the computation of such loss, cost or expense), and the amounts shown on such certificate shall be conclusive and binding absent manifest error. Within ten (10) days of receipt of such certificate, the Borrowers shall pay directly to such Lender such amount as will compensate such Lender for such loss, cost or expense as provided herein. Section 2.14. Commitment Terminations. The Borrowers shall have the right ----------------------- at any time and from time to time, upon five (5) Business Days' prior and irrevocable written notice to the Agent, to terminate or reduce the Revolving Credit Commitments (including the Multicurrency Funding Limit) or the Term Credit Commitments without premium or penalty, in whole or in part, any partial termination to be (i) in an amount not less than $5,000,000 as determined by the Borrowers and in integral multiples of $5,000,000, and (ii) allocated ratably among the Lenders in proportion to their respective Revolving Credit Commitments and among the Lenders in proportion to their respective Term Credit Commitments, as applicable; provided that the Revolving Credit Commitment Amount may not be reduced to an amount less than the sum of the aggregate principal amount of outstanding Revolving Loans plus the aggregate undrawn face amount of outstanding Letters of Credit plus any unpaid Reimbursement Obligations with respect to Letters of Credit, the L/C Commitment Amount may not be reduced to an amount less than the aggregate undrawn face amount of outstanding Letters of Credit plus any unpaid Reimbursement Obligations with respect to Letters of Credit, and the Term Credit Commitment Amount may not be reduced to an amount less than the sum of the aggregate principal amount of outstanding Term Loans, in each case after converting, if necessary, any such outstanding Obligations to Dollars in accordance with Section 10.19 and after giving effect to payments on such proposed termination or reduction date, unless the Borrowers provide to the Agent cash collateral in an amount sufficient to cover such shortage or back to back letters of credit from a bank whose long-term senior unsecured debt rating is rated A or above from either S&P or Moody's or such other bank satisfactory to the Majority Lenders in an amount equal to the undrawn face amount of any applicable outstanding Letters of Credit with an expiration date of 55 at least five (5) days after the expiration date of any applicable Letter of Credit and which provide that the Agent may make a drawing thereunder in the event that it pays a drawing under such Letter of Credit.

Any change to the commitment fee as a result of a change in the Total Funded Debt to Total Capital Ratio shall be effective as of the date provided in the definition of Applicable Margin. (b) Letter of Credit Fees. Commencing upon the date of issuance or --------------------- extension of any Letter of Credit or Agent Letter of Credit, the Borrowers shall pay to the Agent quarterly in advance (pro rated, if necessary for any portion of such quarter) (i) for the ratable account of the Lenders and (ii) to the Agent for its own account, as the case may be, a non-refundable fee equal to the greater of (x) $500, or (y) the face amount of such Letter of Credit or Agent Letter of Credit times the Applicable Margin, calculated in each case on the basis of a 360-day year and actual days elapsed and based on the then scheduled expiration date of the Letter of Credit or the Agent Letter of Credit, as the case may be. Thereafter, such fees shall be payable by the Borrowers in advance on the last Business Day of each calendar quarter of each year commencing with the next succeeding calendar quarter, with the last such payment on the date any such Letter of Credit or Agent Letter of Credit expires.

Any payments received by the Agent from the Borrowers after 1:30 p.m. shall be deemed to have been received on the next Business Day. If the Borrowers do not, or are unable for any reason to, effect payment of a Revolving Loan or Reimbursement Obligation to the Lenders in the applicable currency or if the Borrowers shall default in the 57 payment when due of any payment in such currency, the Lenders may, at their option, require such payment to be made to the Lenders in the Dollar equivalent of such currency determined in accordance with Section 10.19. With respect to any amount due and payable in Pounds or Canadian Dollars, the Borrowers agree to hold the Lenders harmless from any losses incurred by the Lenders arising from any change in the value of Dollars in relation to such currency between the date such payment became due and the date of payment thereof. The Agent will, on the same day each payment is received, cause to be distributed like funds in like currency to each Lender owed an Obligation for which such payment was received, pro rata based on the respective amounts of such type of Obligation then owing to each Lender. (b) If any payment received by the Agent under any Credit Document (including from the proceeds of Collateral) is insufficient to pay in full all amounts then due and payable to the Agent and the Lenders under the Credit Documents, such payment shall be distributed by the Agent and applied by the Agent and the Lenders in the order set forth in Section 7.7. In calculating the amount of Obligations owing each Lender other than for principal and interest on Loans and Reimbursement Obligations and fees under Section 3.1, the Agent shall only be required to include such other Obligations that Lenders have certified to the Agent in writing are due to such Lenders. Section 3.3. Withholding Taxes. (a) Payments Free of Withholding. Except ----------------- ---------------------------- as otherwise required by law and subject to Section 3.3(b), each payment by the Borrowers or any Guarantor to the Agent or any Lender under this Agreement or any other Credit Document shall be made without withholding for or on account of any present or future taxes (other than overall net income taxes on the recipient) imposed by or within the jurisdiction in which such Borrowers or such Guarantor is domiciled, any jurisdiction from which such Borrowers or such Guarantor makes any payment, or (in each case) any political subdivision or taxing authority thereof or therein, excluding, in the case of each Lender and the Agent, taxes, assessments or other governmental charges (i) imposed on, based upon, or measured by its income, and branch profits, franchise and similar taxes imposed on it, by any jurisdiction in which the Agent or such Lender, as the case may be, is incorporated or maintains its principal place of business or Lending Office or which subjects the Agent or such Lender to tax by reason of a connection between the taxing jurisdiction and the Agent or such Lender (other than a connection resulting from the transactions contemplated by this Agreement); (ii) imposed as a result of a connection between the taxing jurisdiction and the Agent or such Lender, as the case may be, other than a connection resulting from the transactions contemplated by this Agreement; (iii) imposed as a result of the transfer by such Lender of its interest in this Agreement or any other Credit Document or a designation by such Lender (other than pursuant to Section 3.3(d) hereof) of a new Lending Office (other than taxes imposed as a result of any change in treaty, law or regulation after such transfer of the Lender's interest in this Agreement or any Credit Document or designation of a new Lending Office); 58 (iv) imposed by the United States of America upon a Lender organized under the laws of a jurisdiction outside of the United States, except to the extent that such tax is imposed or increased as a result of any change in applicable law, regulation or treaty (other than any addition of or change in any "anti-treaty shopping," "limitation of benefits," or similar provision applicable to a treaty) after the date hereof, in the case of each Lender originally a party hereto or, in the case of any Purchasing Lender (as defined in Section 10.10), after the date on which it becomes a Lender; (v) which would not have been imposed but for (a) the failure of the Agent or any Lender, as the case may be, to provide (x) an Internal Revenue Service Form 1001 or 4224, as the case may be, or any substitute or successor form prescribed by the Internal Revenue Service pursuant to Section 3.3(b) below, or (y) any other certification, documentation or proof which is reasonably requested by the Borrower, or (b) a determination by a taxing authority or a court of competent jurisdiction that a certification, documentation or other proof provided by such Lender or the Agent to establish an exemption from such tax, assessment or other governmental charge is false (all such non-excluded taxes, assessments or other governmental charges and liabilities being hereinafter referred to as "Indemnified Taxes"). If any such withholding is so required, such Borrower or Guarantor, as applicable, shall make the withholding, pay the amount withheld to the appropriate governmental authority before penalties attach thereto or interest accrues thereon and forthwith pay such additional amount as may be necessary to ensure that the net amount actually received by the Agent and each Lender is free and clear of such Indemnified Taxes (including Indemnified Taxes on such additional amount) and is equal to the amount that the Agent or such Lender (as the case may be) would have received had such withholding not been made. If the Agent or any Lender pays any amount in respect of any Indemnified Taxes, penalties or interest, such Borrower or Guarantor, as applicable, shall reimburse the Agent or that Lender for the payment on demand in the currency in which such payment was made. If such Borrower or Guarantor pays any Indemnified Taxes, penalties or interest, it shall deliver official tax receipts evidencing the payment or certified copies thereof, or other satisfactory evidence of payment if such tax receipts have not yet been received by such Borrower or such Guarantor (with such tax receipts to be promptly delivered when actually received), to the Agent or the Lender on whose account such withholding was made (with a copy to the Agent if not the recipient of the original) within fifteen (15) days of such payment. (b) U.S. Withholding Tax Exemptions. Each Lender that is not a United ------------------------------- States person (as such term is defined in Section 7701(a)(30) of the Code) shall submit to the Borrowers and the Agent on or before the Effective Date, two duly completed and signed copies of either Form 1001 (entitling such Lender to a complete exemption from withholding under the Code on all amounts to be received by such Lender, including fees, pursuant to the Credit Documents) or Form 4224 (relating to all amounts to be received by such Lender, including fees, pursuant to the Credit Documents) of the Internal Revenue Service. Thereafter and from time to time, each Lender shall submit to the Borrowers and the Agent such additional duly completed and signed copies of one or the other of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may be (i) notified by the Borrowers, directly or through the Agent, to such Lender, and (ii) required under then- current United States law or regulations to avoid United States withholding taxes on 59 payments in respect of all amounts to be received by such Lender, including fees, pursuant to the Credit Documents. Upon the request of the Borrowers, each Lender that is a United States person shall submit to the Borrowers a certificate to the effect that it is such a United States person. (c) Inability of Lender to Submit Forms. If any Lender determines, as a ----------------------------------- result of any change in applicable law, regulation or treaty, or in any official application or interpretation thereof, that it is unable to submit to the Borrowers or the Agent any form or certificate that such Lender is obligated to submit pursuant to Section 3.3(b) or that such Lender is required to withdraw or cancel any such form or certificate previously submitted or any such form or certificate otherwise becomes ineffective or inaccurate, such Lender shall promptly notify the Borrowers and the Agent of such fact and the Lender shall to that extent not be obligated to provide any such form or certificate and will be entitled to withdraw or cancel any affected form or certificate, as applicable. (d) Refund of Taxes. If any Lender or the Agent receives a refund of any --------------- Indemnified Tax or any tax referred to in Section 10.3 with respect to which any Borrower or any Guarantor has paid any amount pursuant to this Section 3.3 or Section 10.3, such Lender or the Agent shall pay the amount of such refund (including any interest received with respect thereto) to such Borrower or such Guarantor.

The Agent, after giving notice to the Borrowers pursuant to Section 7.1(c) or (d) or this Section 7.2, shall also promptly send a copy of such notice to the other Lenders, but the failure to do so shall not impair or annul the effect of such notice.

The Collateral Account shall be held in the name of and subject to the exclusive dominion and control of the Agent, for the benefit of the Agent and the Lenders, as pledgee hereunder. If and when requested by the Borrowers, the Agent shall invest and reinvest funds held in the Collateral Account from time to time in Cash Equivalents specified from time to time by the Borrowers, provided that the Agent is irrevocably authorized to sell investments held in the Collateral Account when and as required to make payments out of the Collateral Account for application to Collateralized 85 Obligations due and owing from the Borrowers to the Agent or Lenders.

SECTION 8. CHANGE IN CIRCUMSTANCES. Section 8.1. Change of Law. Notwithstanding any other provisions of this ------------- Agreement or any Note, if at any time any change in applicable law or regulation or in the interpretation thereof makes it unlawful for any Lender to make or continue to maintain Eurodollar Loans or to give effect to its obligations as contemplated hereby, such Lender shall promptly give notice thereof to the Borrowers and such Lender's obligations to fund loans in Canadian Dollars or Pounds and make, continue or convert Loans into Eurodollar Loans under this Agreement shall be suspended until it is no longer unlawful for such Lender to make or maintain Eurodollar Loans. The Borrowers shall prepay on demand the outstanding principal amount of any such affected Eurodollar Loans, together with all interest accrued thereon and all other amounts then due and payable to such Lender under this Agreement; provided, however, subject to all of the terms and conditions of this Agreement, the Borrowers may then elect to borrow the principal amount of the affected Eurodollar Loans from such Lender by means of Base Rate Loans from such Lender that shall not be made ratably by the Lenders but only by such affected Lender. Section 8.2. Unavailability of Deposits or Inability to Ascertain LIBOR ---------------------------------------------------------- Rate. If on or before the first day of any Interest Period for any Borrowing of - ---- Eurodollar Loans the Agent determines (after consultation with other Lenders) that, due to changes in circumstances since the date hereof, adequate and fair means do not exist for determining the Adjusted LIBOR Rate or such rate will not accurately reflect the cost to the Majority Lenders of funding Eurodollar 87 Loans for such Interest Period, the Agent shall give notice of such determination to the Borrowers and the Lenders, whereupon until the Agent notifies the Borrowers and Lenders that the circumstances giving rise to such suspension no longer exist, the obligations of the Lenders to fund loans in Canadian Dollars or Pounds and make, continue or convert Loans into Eurodollar Loans shall be suspended. Section 8.3. Increased Cost and Reduced Return. (a) If, on or after the --------------------------------- date hereof, the adoption of or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or its Lending Office), including the Agent in its capacity as the issuer of Letters of Credit, with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (i) subjects any Lender of that type (or its Lending Office) to any tax, duty or other charge related to any Eurodollar Loan, Letter of Credit, Agent Letter of Credit, or Reimbursement Obligation, or its participation in any thereof, or its obligation to advance or maintain Eurodollar Loans, issue Letters of Credit, issue Agent Letters of Credit or to participate therein, or shall change the basis of taxation of payments to any Lender (or its Lending Office) of the principal of or interest on its Eurodollar Loans, Letters of Credit, Agent Letters of Credit or participations therein, or any other amounts due under this Agreement related to its Eurodollar Loans, Letters of Credit, Agent Letters of Credit, Reimbursement Obligations, or participations therein, or its obligation to make Eurodollar Loans, issue Letters of Credit, issue Agent Letters of Credit or acquire participations therein (except for changes in the rate of tax on the overall net income of such Lender or its Lending Office imposed by the jurisdiction in which such Lender's principal executive office or Lending Office is located); or (ii) imposes, modifies or deems applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System) against assets of, deposits with or for the account of, or credit extended by, any Lender of that type (or its Lending Office) or imposes on any Lender of that type (or its Lending Office) or on the interbank market any other condition affecting its Eurodollar Loans, its Letters of Credit, its Agent Letters of Credit, any Reimbursement Obligation owed to it, or its participation in any thereof, or its obligation to advance or maintain Eurodollar Loans, issue Letters of Credit, issue Agent Letters of Credit or to participate in any thereof; and the result of any of the foregoing is to increase the cost to such Lender (or its Lending Office) of advancing or maintaining any Eurodollar Loan, issuing or maintaining a Letter of Credit or participation therein, or issuing or maintaining an Agent Letter of Credit, or to reduce the amount of any sum received or receivable by such Lender (or its Lending Office) in connection therewith under this Agreement or its Note(s), by an amount deemed by such Lender to be material, then, within fifteen (15) days after demand in reasonable detail by such Lender (with a copy to the Agent), the Borrowers shall be obligated to pay to such Lender such additional amount or amounts as will compensate such Lender for such increased cost or reduction. 88 (b) If, after the date hereof, the Agent or any Lender shall have determined that the adoption after the date hereof of any applicable law, rule or regulation regarding capital adequacy, or any change therein (including, without limitation, any revision in the Final Risk-Based Capital Guidelines of the Board of Governors of the Federal Reserve System (12 CFR Part 208, Appendix A; 12 CFR Part 225, Appendix A) or of the Office of the Comptroller of the Currency (12 CFR Part 3, Appendix A), or in any other applicable capital adequacy rules heretofore adopted and issued by any governmental authority), or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Agent or any Lender (or its Lending Office) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Lender's capital, or on the capital of any corporation controlling such Lender, as a consequence of its obligations hereunder to a level below that which such Lender could have achieved but for such adoption, change or compliance (taking into consideration such Lender's policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, within fifteen (15) days after demand in reasonable detail by such Lender (with a copy to the Agent), the Borrowers shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction. (c) The Agent and each Lender that determines to seek compensation under this Section 8.3 shall notify the Borrowers and, in the case of a Lender other than the Agent, the Agent of the circumstances that entitle the Agent or Lender to such compensation and will designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole judgment of such Lender, be otherwise disadvantageous to it; provided that, the foregoing shall not in any way affect the rights of any Lender or the obligations of the Borrowers under this Section 8.3, and provided further that no Lender shall be obligated to make its Eurodollar Loans hereunder at any office located in the United States. A certificate of any Lender claiming compensation under this Section 8.3 and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods. Section 8.4. Lending Offices. The Agent and each Lender may, at its --------------- option, elect to make its Loans hereunder at the Lending Office for each type of Loan available hereunder or at such other of its branches, offices or Affiliates as it may from time to time elect and designate in a written notice to the Borrowers and the Agent subject to Section 8.3(c). Section 8.5. Discretion of Lender as to Manner of Funding. -------------------------------------------- Notwithstanding any other provision of this Agreement, each Lender shall be entitled to fund and maintain its funding of all or any part of its Loans in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if each Lender had actually funded and maintained each Eurodollar Loan through the purchase of deposits in the eurodollar interbank market having a maturity corresponding to such Loan's Interest Period and bearing an interest rate equal to LIBOR for such Interest Period. 89 Section 8.6. Substitution of Lender. If (i) any Lender has demanded ---------------------- compensation or given notice of its intention to demand compensation under Section 8.3, or (ii) the Borrowers are required to pay any additional amount to any Lender under Section 2.13, the Borrowers shall have the right, with the assistance of the Agent, to seek a substitute lender or lenders reasonably satisfactory to the Agent (which may be one or more of the Lenders) to replace such Lender under this Agreement. The Lender to be so replaced shall cooperate with the Borrowers and substitute lender to accomplish such substitution on the terms of Section 10.10, as applicable, provided that all such Lender's Commitments are replaced and such Lender is paid any amounts which it is owed pursuant to Sections 2.13, 3.3, 7.6, 8.3 and 10.13. Any such replaced Lender shall retain the benefit of Sections 3.3 and 10.13. SECTION 9. THE AGENT. Section 9.1. Appointment and Authorization of Agent. Each Lender hereby -------------------------------------- appoints ABN AMRO Bank N.V. as the Agent and the Collateral Agent under the Credit Documents and hereby authorizes the Agent and the Collateral Agent to take such action as Agent or the Collateral Agent on its behalf and to exercise such powers under the Credit Documents as are delegated to the Agent and the Collateral Agent by the terms thereof, together with such powers as are reasonably incidental thereto. Section 9.2. Rights and Powers. The Agent and the Collateral Agent shall ----------------- have the same rights and powers under the Credit Documents as any other Lender and may exercise or refrain from exercising such rights and power as though it were not the Agent or the Collateral Agent, and the Agent, the Collateral Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of business with Holdings, any of the Borrowers or any of their Subsidiaries or Affiliates as if it were not the Agent or the Collateral Agent under the Credit Documents. The term Lender as used in all Credit Documents, unless the context otherwise clearly requires, includes the Agent and the Collateral Agent in its individual capacity as a Lender, including its capacity as a Lender under the Agent Swing Line. References herein to the Agent's and the Collateral Agent's Loans, or to the amount owing to the Agent and the Collateral Agent for which an interest rate is being determined, refer to the Agent and the Collateral Agent in its individual capacity as a Lender. Section 9.3. Action by Agent. The obligations of the Agent and the --------------- Collateral Agent under the Credit Documents are only those expressly set forth therein. Without limiting the generality of the foregoing, the Agent shall not be required to take any action concerning any Default or Event of Default, except as expressly provided in Sections 7.2 and 7.5. Upon the occurrence of an Event of Default, the Agent and the Collateral Agent shall take such action to enforce its Lien on the Collateral and to preserve and protect the Collateral as may be directed by the Majority Lenders. Unless and until the Majority Lenders give such direction, the Agent and the Collateral Agent may take or refrain from taking such actions as it deems appropriate and in the best interest of all the Lenders. In no event, however, shall the Agent and the Collateral Agent be required to take any action in violation of applicable law or of any provision of any Credit Document, and the Agent and the Collateral Agent shall in all cases be fully justified in failing or refusing to act hereunder or under any other Credit Document unless it first receives any further assurances of its indemnification from the Lenders that it may require, including prepayment of any related expenses and any other protection it requires against any 90 and all costs, expenses, and liabilities it may incur in taking or continuing to take any such action. The Agent and the Collateral Agent shall be entitled to assume that no Default or Event of Default exists unless notified in writing to the contrary by a Lender or the Borrowers. In all cases in which the Credit Documents do not require the Agent or the Collateral Agent to take specific action, as applicable, the Agent and the Collateral Agent shall be fully justified in using its discretion in failing to take or in taking any action thereunder. Any instructions of the Majority Lenders, or of any other group of Lenders called for under specific provisions of the Credit Documents, shall be binding on all the Lenders and holders of Notes. Section 9.4. Consultation with Experts. The Agent and the Collateral ------------------------- Agent may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts. Section 9.5. Indemnification Provisions. Neither the Agent nor the -------------------------- Collateral Agent nor any of their directors, officers, agents, or employees shall be liable for any action taken or not taken by it in connection with the Credit Documents (i) with the consent or at the request of the Majority Lenders or (ii) in the absence of its own gross negligence or willful misconduct. Neither the Agent nor the Collateral Agent nor any of their directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into or verify (i) any statement, warranty or representation made in connection with this Agreement, any other Credit Document or any Borrowing; (ii) the performance or observance of any of the covenants or agreements of Holdings, any of the Borrowers or any Subsidiary contained herein or in any other Credit Document; (iii) the satisfaction of any condition specified in Section 4 hereof, except receipt of items required to be delivered to the Agent; or (iv) the validity, effectiveness, genuineness, enforceability, perfection, value, worth or collectability hereof or of any other Credit Document or of the Liens provided for by the Security Documents or of any other documents or writing furnished in connection with any Credit Document or of the Collateral; and the Agent and the Collateral Agent makes no representation of any kind or character with respect to any such matters mentioned in this sentence. The Agent and the Collateral Agent may execute any of its duties under any of the Credit Documents by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Lenders or any other Person for the default or misconduct of any such agents or attorneys-in-fact selected with reasonable care. The Agent and the Collateral Agent shall not incur any liability by acting in reliance upon any notice, consent, certificate, other document or statement (whether written or oral) believed by it to be genuine or to be sent by the proper party or parties. In particular and without limiting any of the foregoing, the Agent and the Collateral Agent shall have no responsibility for confirming the existence or worth of any Collateral or the accuracy of any Compliance Certificate or other document or instrument received by it under the Credit Documents. The Agent and the Collateral Agent may treat the payee of any Note as the holder thereof until written notice of transfer shall have been filed with the Agent and the Collateral Agent signed by such owner in form satisfactory to the Agent and the Collateral Agent. Each Lender acknowledges that it has independently and without reliance on the Agent and the Collateral Agent or any other Lender obtained such information and made such investigations and inquiries regarding Holdings, the Borrowers and their Subsidiaries as it deems important, and based upon such information, investigations and inquiries made its own credit analysis and decision to extend credit to the Borrowers in the manner set forth in the Credit Documents. It shall be the responsibility of each 91 Lender to keep itself informed about the creditworthiness and business properties, assets, liabilities, condition (financial or otherwise) and prospects of Holdings, the Borrowers and their Subsidiaries, the creditworthiness of all account debtors of Holdings, the Borrowers and their Subsidiaries, and the Agent and the Collateral Agent shall have no liability whatsoever to any Lender for such matters. The Agent and the Collateral Agent shall have no duty to disclose to the Lenders information that is not required by any Credit Document to be furnished by Holdings, the Borrowers or any Subsidiaries to the Agent and the Collateral Agent at such time, but is voluntarily furnished to the Agent and the Collateral Agent (either in its capacity as Agent or Collateral Agent or in its individual capacity). Section 9.6. Indemnity. The Lenders shall ratably, in accordance with --------- their Percentages, indemnify and hold the Agent and the Collateral Agent, and its directors, officers, employees, agents and representatives harmless from and against any liabilities, losses, costs or expenses suffered or incurred by it or by any security trustee under any Credit Document or in connection with the transactions contemplated thereby, regardless of when asserted or arising, except to the extent they are promptly reimbursed for the same by the Borrowers or out of the proceeds of the Collateral and except to the extent that any event giving rise to a claim was caused by the gross negligence or willful misconduct of the party seeking to be indemnified. The obligations of the Lenders under this Section 9.6 shall survive termination of this Agreement. Section 9.7. Resignation of Agent and Successor Agent. The Agent and the ---------------------------------------- Collateral Agent may resign at any time upon at least thirty (30) days' prior written notice to the Lenders and the Borrowers. Upon any such resignation of the Agent or the Collateral Agent, the Majority Lenders, with the consent of the Borrowers (which consent shall not be unreasonably withheld) shall have the right to appoint a successor Agent or Collateral Agent, as the case may be. If no successor Agent or Collateral Agent, as the case may be, shall have been so appointed by the Majority Lenders and shall have accepted such appointment within thirty (30) days after the retiring Agent's or Collateral Agent's giving of notice of resignation, then the retiring Agent or Collateral Agent, as the case may be, may, on behalf of the Lenders, appoint a successor Agent or Collateral Agent, as the case may be, which shall be any Lender hereunder or any commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $500,000,000. Upon the acceptance of its appointment as the Agent or the Collateral Agent hereunder, such successor Agent or Collateral Agent, as the case may be, shall thereupon succeed to and become vested with all the rights and duties of the retiring Agent or Collateral Agent, as the case may be, under the Credit Documents, and the retiring Agent or Collateral Agent, as the case may be, shall be discharged from its duties and obligations thereunder. After any retiring Agent's or Collateral Agent's resignation hereunder as Agent or Collateral Agent, as the case may be, the provisions of this Section 9 and all protective provisions of the other Credit Documents shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent or Collateral Agent, as the case may be. SECTION 10. MISCELLANEOUS. Section 10.1. No Waiver of Rights. No delay or failure on the part of the ------------------- Agent or any Lender, or on the part of the holder or holders of any Notes, in the exercise of any power, right 92 or remedy under any Credit Document shall operate as a waiver thereof or as an acquiescence in any default, nor shall any single or partial exercise thereof preclude any other or further exercise of any other power, right or remedy. To the fullest extent permitted by applicable law, the powers, rights and remedies under the Credit Documents of the Agent, the Collateral Agent, the Lenders and the holder or holders of any Notes are cumulative to, and not exclusive of, any rights or remedies any of them would otherwise have. Section 10.2. Non-Business Day. If any payment of principal or interest ---------------- on any Loan, Reimbursement Obligation or of any other Obligation shall fall due on a day which is not a Business Day, interest or fees (as applicable) at the rate, if any, such Loan or other Obligation bears for the period prior to maturity shall continue to accrue in the manner set forth herein on such Obligation from the stated due date thereof to and including the next succeeding Business Day, on which the same shall be payable. Section 10.3. Documentary Taxes. The Borrowers agree that they will pay ----------------- any documentary, stamp or similar taxes payable with respect to any Credit Document, including interest and penalties, in the event any such taxes are assessed irrespective of when such assessment is made and regardless whether any credit is then in use or available hereunder. Section 10.4. Survival of Representations. All representations and --------------------------- warranties made herein or in certificates given pursuant hereto shall survive the execution and delivery of this Agreement and the other Credit Documents, and shall continue in full force and effect with respect to the date as of which they were made as long as the Borrowers have any Obligation hereunder or any Commitment or Agent Credit Commitment hereunder is in effect. Section 10.5. Survival of Indemnities. All indemnities and all other ----------------------- provisions relative to reimbursement to the Lenders of amounts sufficient to protect the yield of the Lenders with respect to the Loans, including, but not limited to, Section 2.13, Section 3.3, Section 7.6, Section 8.3 and Section 10.13 hereof, shall survive the termination of this Agreement and the other Credit Documents and the payment of the Loans and all other Obligations for a period of one (1) year. Section 10.6. Setoff. In addition to any rights now or hereafter granted ------ under applicable law and not by way of limitation of any such rights, upon the occurrence of, and throughout the continuance of, any Default or Event of Default, each Lender and each subsequent holder of any Note is hereby authorized by the Borrowers at any time or from time to time, without notice to the Borrowers, to Holdings, to any Subsidiary Guarantor or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, Indebtedness evidenced by certificates of deposit, whether matured or unmatured, but not including trust accounts, and in whatever currency denominated) and any other Indebtedness at any time held or owing by that Lender or that subsequent holder to or for the credit or the account of any of the Borrowers, whether or not matured, against and on account of the obligations and liabilities of any of the Borrowers to that Lender or that subsequent holder under the Credit Documents, including, but not limited to, all claims of any nature or description arising out of or connected with the Credit Documents, irrespective of whether or not (i) that Lender or that subsequent holder shall have made any demand hereunder or (ii) the principal of or the interest on the Loans or Notes and 93 other amounts due hereunder shall have become due and payable hereunder and although said obligations and liabilities, or any of them, may be contingent or unmatured. Each Lender agrees with each other Lender a party hereto that if such Lender receives and retains any payment, whether by setoff or application of deposit balances or otherwise, on any of the Loans or L/C Obligations in excess of its ratable share of payments on all such Obligations then owed to the Lenders hereunder, then such Lender shall purchase for cash at face value, but without recourse, ratably from each of the other Lenders such amount of the Loans or L/C Obligations, or participations therein, held by each such other Lenders (or interest therein) as shall be necessary to cause such Lender to share such excess payment ratably with all the other Lenders; provided, however, that if any such purchase is made by any Lender, and if such excess payment or part thereof is thereafter recovered from such purchasing Lender, the related purchases from the other Lenders shall be rescinded ratably and the purchase price restored as to the portion of such excess payment so recovered, but without interest. Section 10.7. Notices. Except as otherwise specified herein, all notices ------- under the Credit Documents shall be in writing (including cable, telecopy or telex) and shall be given to a party hereunder at its address, telecopier number or telex numbers set forth below or such other address, telecopier number or telex as such party may hereafter specify by notice to the Agent and the Borrowers, given by courier, by United States certified or registered mail, by telegram or by other telecommunication device capable of creating a written record of such notice and its receipt.

This Agreement may be executed in any number ------------ of counterparts, and by the different parties on different counterpart signature pages, each of which when executed shall be deemed an original but all such counterparts taken together shall constitute one and the same Agreement. Section 10.9. Successors and Assigns. This Agreement shall be binding ---------------------- upon the Borrowers and their respective successors and assigns, and shall inure to the benefit of each of the Lenders and their respective successors and assigns, including any subsequent holder of any Note. Except as expressly permitted in Section 6.13, none of the Borrowers may assign any of its rights or obligations under any Credit Document without the written consent of all of the Lenders. Section 10.10. Sales and Transfers of Borrowings and Notes; Participations ----------------------------------------------------------- in Borrowings and Notes. - ----------------------- (a) Any Lender may at any time sell to one or more banks ("Participants"), participating interests in any Borrowing owing to such Lender, any Note held by such Lender, any Commitment or Agent Credit Commitment of such Lender or any other interest of such Lender hereunder, provided that no Lender may sell any participating interests in any such Borrowing, Note, Commitment, Agent Credit Commitment or other interest hereunder without also selling to such Participant the appropriate pro rata share of its Borrowings, Notes, Commitments, Agent Credit Commitments and other interests hereunder, and provided further that no Lender shall transfer, grant or assign any participation under which the Participant shall have rights to vote upon or consent to any matter to be decided by the Lender or the Majority Lenders hereunder or under any Credit Document or approve any amendment to or waiver of this Agreement or any other Credit Document except to the extent such amendment or waiver would (i) increase the amount of such Lender's Commitment or Agent Credit Commitment and such increase would affect such Participant, (ii) reduce the principal of, or interest on, any of such Lender's Borrowings, or any fees or other amounts payable to such Lender hereunder and such reduction would affect such Participant, (iii) postpone any date fixed for any scheduled payment of principal of, or interest on, any of such Lender's Borrowings, or any fees or other amounts payable to such Lender hereunder, or (iv) release all or substantially all collateral security for any Obligation (including, without limitation, the Parent Company Guaranty or any Limited Subsidiary Guaranty), except as otherwise specifically provided in any Credit Document. In the event of any such sale by a Lender of participating interests to a Participant, such Lender's obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Note for all purposes under this Agreement and the Borrowers and the Agent shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. The Borrowers agree that if amounts outstanding under this Agreement and the Notes are due and unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall be deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement and any Note to the same extent 95 as if the amount of its participating interest were owing directly to it as a Lender under this Agreement or any Note, provided that such right of setoff shall be subject to the obligation of such Participant to share with the Lenders, and the Lenders agree to share with such Participant, as provided in Section 10.6. The Borrowers also agree that each Participant shall be entitled to the benefits of Sections 2.13 and 8.3 with respect to its participation in the Commitments and the Borrowings outstanding from time to time, provided that no Participant shall be entitled to receive any greater amount pursuant to such Sections than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred. (b) Any Lender may at any time sell to any Lender or any Affiliate thereof, and, with the consent of the Agent and the Borrowers (which shall not be unreasonably withheld or delayed), to one or more banks (a "Purchasing Lender"), all or any part of its rights and obligations under this Agreement and the Notes, pursuant to an Assignment Agreement in the form attached as Exhibit 10.10 hereto, executed by such Purchasing Lender and such transferor Lender (and, in the case of a Purchasing Lender which is not then a Lender or an Affiliate thereof, by the Borrowers and the Agent) and delivered to the Agent; provided that, each such sale to a Purchasing Lender shall be in an amount of $10,000,000 or more, or if in a lesser amount, such sale shall be of all of the Lender's rights and obligations under this Agreement and all of the Notes payable to it to one eligible assignee. Notwithstanding the above, any Lender may sell to one or more eligible assignees all or any part of their rights and obligations under this Agreement and the Notes with only the consent of the Agent (which shall not be unreasonably withheld) if an Event of Default shall have occurred and be continuing. No Lender may sell any Loans to a Purchasing Lender without also selling to such Purchasing Lender the appropriate pro rata share of its Borrowings, Notes, Commitments and other interests hereunder, including participations in Letters of Credit hereunder; provided that, the Agent shall not be required to sell its Agent Revolving Obligations and its Agent Credit Commitment at such time as it may sell any other portion of its Borrowings, Notes, Commitments and other interests hereunder. Upon such execution, delivery, acceptance and recording, from and after the effective date of the transfer determined pursuant to such Assignment Agreement (x) the Purchasing Lender thereunder shall be a party hereto and, to the extent provided in such Assignment Agreement, have the rights and obligations of a Lender hereunder with a Commitment as set forth therein and (y) the transferor Lender thereunder shall, to the extent provided in such Assignment Agreement, be released from its obligations under this Agreement (and, in the case of an Assignment Agreement covering all or the remaining portion of a transferor Lender's rights and obligations under this Agreement, such transferor Lender shall cease to be a party hereto). Such Assignment Agreement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing Lender and the resulting adjustment of Commitments and Percentages arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement, the Notes and the other Credit Documents. On or prior to the effective date of the transfer determined pursuant to such Assignment Agreement, the Borrowers, at their own expense, shall execute and deliver to the Agent in exchange for any surrendered Notes, new Notes as appropriate to the order of such Purchasing Lender in an amount equal to the Commitments assumed by it pursuant to such Assignment Agreement, and, if the transferor Lender has retained a Commitment or Borrowing hereunder, new Notes to the order of the transferor Lender in an amount equal to the Commitments or Borrowings retained by it hereunder. Such new Notes shall be dated the Initial Borrowing Date and shall otherwise 96 be in the form of the Notes replaced thereby. The Notes surrendered by the transferor Lender shall be returned by the Agent to the Borrowers marked "cancelled." (c) Upon its receipt of an Assignment Agreement executed by a transferor Lender, a Purchasing Lender and the Agent (and, in the case of a Purchasing Lender that is not then a Lender or an Affiliate thereof, by the Borrowers), together with payment to the Agent hereunder of a registration and processing fee of $3,500, the Agent shall (i) promptly accept such Assignment Agreement, and (ii) on the effective date of the transfer determined pursuant thereto give notice of such acceptance and recordation to the Lenders and the Borrowers. (d) The provisions of the foregoing clauses (b) and (c) shall not apply to or restrict, or require the consent of or any notice to any Person to effectuate, the pledge or assignment by any Lender of its rights under this Agreement and its Notes to any Federal Reserve Bank. (e) If, pursuant to this Section 10.10 any interest in this Agreement or any Note is transferred to any transferee which is organized under the laws of any jurisdiction other than the United States of America or any State thereof, the transferor Lender shall cause such transferee, concurrently with the effectiveness of such transfer, (i) to represent to the transferor Lender (for the benefit of the transferor Lender, the Agent and the Borrowers) that under applicable law and treaties no taxes will be required to be withheld by the Agent, the Borrowers or the transferor Lender with respect to any payments to be made to such transferee in respect of the Loans or the L/C Obligations, (ii) to furnish to the transferor Lender (and, in the case of any Purchasing Lender, the Agent and the Borrowers) either U.S. Internal Revenue Service Form 4224 or U.S. Internal Revenue Service Form 1001 or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities (wherein such transferee claims entitlement to complete exemption from U.S. federal withholding tax on all interest payments hereunder), and (iii) to agree (for the benefit of the transferor Lender, the Agent and the Borrowers) to provide the transferor Lender (and, in the case of any Purchasing Lender, the Agent and the Borrowers) a new Form 4224 or Form 1001 upon the expiration or obsolescence of any previously delivered form and comparable statements in accordance with applicable U.S. laws and regulations and amendments dully executed and completed by such Transferee, and to comply from time to time with all applicable U.S. laws and regulations with regard to such withholding tax exemption. Section 10.11. Amendments. Any provision of the Credit Documents may be ---------- amended or waived if, but only if, such amendment or waiver is in writing and is signed by (a) the Borrowers, (b) the Majority Lenders, and (c) if the rights or duties of the Agent are affected thereby, the Agent; provided that: (i) no amendment or waiver shall (A) increase the Original Commitment Amount, the Revolving Credit Commitment Amount, the Term Credit Commitment Amount, the Total Commitment Amount or the Agent Commitment Amount without the consent of all Lenders or increase any Commitment of any Lender without the consent of such Lender, (B) postpone any Maturity Date without the consent of all Lenders (or ABN AMRO in the case of Agent Revolving Loans) or reduce the amount of or postpone the date for any scheduled payment of any principal of or interest on any Loan or Reimbursement Obligation or of any fee payable hereunder without the consent of each Lender owed such Obligation or (C) release any 97 Collateral, the Parent Company Guaranty or any Limited Subsidiary Guaranty without the consent of all the Lenders; and (ii) no amendment or waiver shall, unless signed by each Lender, change the provisions of this Section 10.11 or the definition of Majority Lenders or affect the number of Lenders required to take any action under any other provision of the Credit Documents. Section 10.12. Headings. Section headings used in this Agreement are for -------- reference only and shall not affect the construction of this Agreement. Section 10.13. Legal Fees, Other Costs and Indemnification. The Borrowers, ------------------------------------------- upon demand by the Agent, agree to pay the reasonable fees and disbursements of legal counsel to the Agent in connection with the preparation and execution of the Credit Documents, and any amendment, waiver or consent related thereto, whether or not the transactions contemplated therein are consummated (provided that the Borrowers shall be obligated hereunder to pay such fees and disbursements for only one (1) law firm and any local counsel), and all reasonable recording, filing, or other fees, costs and taxes incident to perfecting a Lien upon the Collateral described in the Security Documents. The Borrowers further agree to indemnify each Lender, the Agent, the Collateral Agent, the Syndication Agent, and their respective directors, officers, employees and attorneys (collectively, the "Indemnified Parties"), against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all reasonable attorneys' fees and other reasonable expenses of litigation or preparation therefor, whether or not the indemnified Person is a party thereto) which any of them may pay or incur arising out of or relating to (a) any Credit Document, the Loans or the application or proposed application by any of the Borrowers of the proceeds of any Loan, REGARDLESS OF WHETHER SUCH CLAIMS OR ACTIONS ARE FOUNDED IN WHOLE OR IN PART UPON THE ALLEGED SIMPLE OR CONTRIBUTORY NEGLIGENCE OF ANY OF THE INDEMNIFIED PARTIES AND/OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES OR ATTORNEYS, (b) any investigation of any third party or any governmental authority involving any Lender (as a lender hereunder), the Agent (in such capacity hereunder), the Collateral Agent (in such capacity hereunder), or the Syndication Agent (in such capacity hereunder) and related to any use made or proposed to be made by the Borrowers of the proceeds of the Borrowings, or any transaction financed or to be financed in whole or in part, directly or indirectly with the proceeds of any Borrowing, and (c) any investigation of any third party or any governmental authority, litigation or proceeding, related to any environmental cleanup, audit, compliance or other matter relating to any Environmental Law or the presence of any Hazardous Material (including, without limitation, any losses, liabilities, damages, injuries, costs, expenses or claims asserted or arising under any Environmental Law) with respect to any of the Borrowers, regardless of whether caused by, or within the control of, any of the Borrowers; provided, however, that the Borrowers shall not be obligated to indemnify any Indemnified Party for any of the foregoing arising out of such Indemnified Party's gross negligence or willful misconduct. The Borrowers, upon demand by the Agent, the Collateral Agent, the Syndication Agent or a Lender at any time, shall reimburse the Agent, the Collateral Agent, the Syndication Agent or such Lender for (i) any legal or other expenses incurred in connection with investigating or defending against any of the foregoing except if the same is excluded from indemnification pursuant to the provisions of the foregoing sentence and (ii) if an Event of Default has occurred and is continuing, reasonable fees of legal 98 counsel (including the allocated costs of in-house counsel) in connection with the Agent's, the Collateral Agent's, the Syndication Agent's or such Lender's enforcement of their rights and remedies in the Credit Documents. Section 10.14. Governing Law; Submission to Jurisdiction; Waiver of Jury --------------------------------------------------------- Trial. This Agreement and the other Credit Documents, and the rights and duties - ----- of the parties thereto, shall be construed in accordance with and governed by the internal laws of the State of New York. The Borrowers hereby submit to the nonexclusive jurisdiction of the United States District Court for the Southern District of New York and of any New York State court sitting in the City of New York for purposes of all legal proceedings arising out of or relating to this Agreement, any other Credit Document or the transactions contemplated thereby. The Borrowers irrevocably waive, to the fullest extent permitted by law, any objection they may now or hereafter have to the laying of the venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum. EACH PARTY TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY. Section 10.15. Confidentiality. Each Lender agrees it will not disclose --------------- without the Borrowers' consent (other than to its employees, auditors, counsel or other professional advisors, to its Affiliates or to another Lender) any information concerning Holdings, the Borrowers or any of its Subsidiaries furnished pursuant to any of the Credit Documents; provided that any Lender may disclose any such information (i) that has become generally available to the public other than through the Lenders, (ii) if required or appropriate in any examination or audit or any report, statement or testimony submitted to any federal or state regulatory body having or claiming to have jurisdiction over such Lender, (iii) if required or appropriate in response to any summons or subpoena or in connection with any litigation, (iv) in order to comply with any law, order, regulation or ruling applicable to such Lender, (v) to any prospective or actual permitted transferee in connection with any contemplated or actual permitted transfer of any of the Notes or any interest therein by such Lender, and (vi) in connection with the exercise of any remedies by the Agent or any Lender; provided that such actual or prospective transferee executes an agreement with such Lender containing provisions substantially identical to those contained in this Section 10.15 prior to such transferee's receipt of any such information. Section 10.16. Effectiveness. This Agreement shall become effective on the ------------- date (the "Effective Date") on which the Borrower, the Agent and each Lender has signed and delivered to the Agent a counterparty signature page hereto or, in the case of a Lender, the Agent has received telex or facsimile notice that such a counterpart has been signed and mailed to the Agent. Section 10.17. Severability. Any provision of this Agreement that is ------------ prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 99 Section 10.18. Currency Conversion. All payments of Obligations under this ------------------- Agreement, the Notes or any other Credit Document shall be made in Dollars, except for Revolving Loans funded, or Reimbursement Obligations with respect to Letters of Credit issued, in Pounds or Canadian Dollars, which shall be repaid, including interest thereon, in the applicable currency. If any payment of any Obligation, except for Revolving Loans funded in Pounds or Canadian Dollars or any Reimbursement Obligation with respect to Letters of Credit issued in Pounds or Canadian Dollars, whether through payment by the Borrowers, Holdings, any Subsidiary Guarantor or the proceeds of any Collateral, shall be made in a currency other than Dollars, such amount shall be converted into Dollars at the official rate for the purchase of Dollars with the applicable currency as quoted by the Agent in accordance with the methods customarily used by the Agent for such purposes as of the close of business on the date of determination. If for the purposes of obtaining any judgment or award it becomes necessary to convert from either Pounds or Canadian Dollars into Dollars any amount in connection with the Obligations, then the conversion shall be made as provided above on the Business Day before the day on which the judgment or award is given. In the event that there is a change in the rate of exchange prevailing between the Business Day before the day on which the judgment or award is given and the date of payment, the Borrowers will pay to the Agent such additional amounts (if any) as may be necessary, and the Agent will pay to the Borrowers such excess amounts (if any) as result from such change in the rate of exchange, to assure that the amount paid on such date is the amount in Pounds or Canadian Dollars, as applicable, which when converted at the rate of exchange described herein on the date of payment, is the amount then due in Dollars. Any amount due from the Borrowers under this Section 10.18 shall be due as a separate debt and shall not be affected by judgment or award being obtained for any other sum due. Section 10.19. Dollar Equivalent Combinations. Unless otherwise provided ------------------------------ herein, to the extent that the determination of compliance with any requirement of this Agreement requires the conversion to Dollars of foreign currency amounts, such Dollar amount shall be computed using the Dollar equivalent of the amount of such foreign currency at the time such item is to be calculated or is incurred, created, transferred or sold for purposes of this Agreement. The Dollar equivalent shall be determined by converting such currency involved in such computation into Dollars at the spot rate for the purchase of Dollars with the applicable currency as quoted by the Agent in accordance with the methods customarily used by the Agent for such purposes as of the close of business on the date of determination thereof specified herein or, if the date of determination thereof is not otherwise specified herein, on the date two (2) applicable Business Days prior to such determination. Section 10.20. Change in Accounting Principles or Tax Laws. If (i) any ------------------------------------------- change in accounting principles from those used in the preparation of the financial statements of the Borrowers referred to in Section 5.9 is hereafter occasioned by the promulgation of rules, regulations, pronouncements and opinions by or required by the Financial Accounting Standards Board or the American Institute of Certified Public Accounts (or successors thereto or agencies with similar functions) and such change materially affects the calculation of any component of any financial covenant, standard or term found in this Agreement, or (ii) there is a material change in federal or foreign tax laws which materially affects the Borrowers ability to comply with the financial covenants, standards or terms found in this Agreement, the Borrowers and the Majority Lenders agree to enter into negotiations in order to amend such provisions so as to equitably reflect such changes with the desired result that the criteria for evaluating any of 100 Holdings' and its Subsidiaries' consolidated financial condition shall be the same after such changes as if such changes had not been made. Unless and until such provisions have been so amended, the provisions of this Agreement shall govern. Section 10.21. Notice. The Credit Documents constitute the entire ------ understanding among the Borrowers, the Lenders, and the Agent and supersede all earlier or contemporaneous agreements, whether written or oral, concerning the subject matter of the Credit Documents.
