The issuance of each Letter of Credit shall confer upon each Lender the benefits and liabilities of a participation consisting of an undivided pro rata interest in the Letter of Credit to the extent of such Lender’s Commitment Percentage.

(ii) Request for Letter of Credit. Each request for a Letter of Credit shall be delivered to Agent (and to the Fronting Lender, if the Fronting Lender is a Lender other than Agent) by an Authorized Officer not later than 11:00 A.M. (Mountain time) three Business Days prior to the day upon which the Letter of Credit is to be issued. Each such request shall be in a form acceptable to Agent (and the Fronting Lender, if the Fronting Lender is a Lender other than Agent) and shall specify the face amount thereof, the account party, the beneficiary, the intended date of issuance, the expiry date thereof, the Alternate Currency if other than Dollars are requested, and the nature of the transaction to be supported thereby. Concurrently with each such request, Administrative Borrower, and any Credit Party for whose account the Letter of Credit is to be issued (which may be a Borrower or a Guarantor of Payment), shall execute and deliver to the Fronting Lender an appropriate application and agreement, being in the standard form of the Fronting Lender for such letters of credit, as amended to conform to the provisions of this Agreement if required by Agent. Agent shall give the Fronting Lender and each Lender notice of each such request for a Letter of Credit.

(iii) Letter of Credit Fees. With respect to each Letter of Credit and the drafts thereunder, if any, whether issued for the account of a Borrower or any other Credit Party, US Borrowers agree (and each Foreign Borrower agrees to pay, with respect to Letters of Credit issued for its own account) to (A) pay to Agent, for the pro rata benefit of the Lenders, a non-refundable commission based upon the face amount of such Letter of Credit, which shall be paid quarterly in arrears, on each Regularly Scheduled Payment Date, at the rate per annum of the Applicable Margin (in effect on such Regularly Scheduled Payment Date) multiplied by the face amount of such Letter of Credit; (B) pay to Agent, for the sole benefit of the Fronting Lender, an additional Letter of Credit fee, which shall be paid on each date that such Letter of Credit shall be issued, amended or renewed at the rate of one-eighth percent (1/8%) of the face amount of such Letter of Credit; and (C) pay to Agent, for the sole benefit of the Fronting Lender, such other issuance, amendment, negotiation, draw, acceptance, telex, courier, postage and similar transactional fees as are generally charged by the Fronting Lender under its fee schedule as in effect from time to time.

(iv) Refunding of Letters of Credit with Revolving Loans. Whenever a Letter of Credit shall be drawn, US Borrowers, and any Foreign Borrower for whose account such Letter of Credit was issued, shall immediately reimburse the Fronting Lender for the amount drawn. In the event that the amount drawn is not in an Alternate Currency and shall not have been reimbursed by such Borrowers, as applicable, within one Business Day of the drawing of such Letter of Credit, at the sole option of Agent (and the Fronting Lender, if the Fronting Lender is a Lender other than Agent), such Borrowers shall be deemed to have requested a Revolving Loan, subject to the provisions of subsection (a) of this Section 2.2 and Section 2.5 hereof (other than the requirement set forth in Section 2.5(d) hereof), in the amount drawn. Such Revolving Loan shall be evidenced by the Revolving Credit Notes. Each Lender agrees, subject to no conditions precedent whatsoever, to make a Revolving Loan on the date of receipt of notice from Agent of a request to make such Revolving Loan. Each Lender acknowledges and agrees that its obligation to make a Revolving Loan pursuant to subsection (a) of this Section 2.2 when required by this Section 2.2(b)(iv) shall be absolute and unconditional and shall not be affected by any circumstance whatsoever, including, without limitation, the occurrence and continuance of a Default or Event of Default, and that its payment to Agent, for the account of the Fronting Lender, of the proceeds of such Revolving Loan shall be made without any offset, abatement, recoupment, counterclaim, withholding or reduction whatsoever and whether or not such Lender’s Revolving Credit Commitment shall have been reduced or terminated. Borrowers irrevocably authorize and instruct Agent to apply the proceeds of any borrowing pursuant to this subsection (iv) to reimburse, in full (other than the Fronting Lender’s pro rata share of such borrowing), the Fronting Lender for the amount drawn on such Letter of Credit. Each such Revolving Loan shall be deemed to be a Base Rate Loan unless otherwise requested by and available to Borrowers hereunder. Each Lender is hereby authorized to record on its records relating to its Revolving Credit Note such Lender’s pro rata share of the amounts paid and not reimbursed on the Letters of Credit.

(v) Participation in Letters of Credit. If, for any reason, the Fronting Lender shall be unable to or, in the opinion of Agent, it shall be impracticable to, convert any Letter of Credit to a Revolving Loan pursuant to the preceding subsection or if the amount not reimbursed is a Letter of Credit drawn in an Alternate Currency, the Fronting Lender shall have the right to request that each Lender purchase a participation in the amount due with respect to such Letter of Credit, and Agent shall promptly notify each Lender thereof (by facsimile or telephone, confirmed in writing). Upon such notice, but without further action, the Fronting Lender hereby agrees to grant to each Lender, and each Lender hereby agrees to acquire from the Fronting Lender, an undivided participation interest in the amount due with respect to such Letter of Credit in an amount equal to such Lender’s Commitment Percentage of the principal amount due with respect to such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to Agent, for the account of the Fronting Lender, such Lender’s ratable share of the amount due with respect to such Letter of Credit (determined in accordance with such Lender’s Commitment Percentage). Each Lender acknowledges and agrees that its obligation to acquire participations in the amount due under any Letter of Credit that is drawn but not reimbursed by Borrowers pursuant to this subsection (v) shall be absolute and unconditional and shall not be affected by any circumstance whatsoever, including, without limitation, the occurrence and continuance of a Default or Event of Default, and that each such payment shall be made without any offset, abatement, recoupment, counterclaim, withholding or reduction whatsoever and whether or not such Lender’s Revolving Credit Commitment shall have been reduced or terminated. Each Lender shall comply with its obligation under this subsection (v) by wire transfer of immediately available funds in Dollars (except in the case of a Letter of Credit issued and drawn in an Alternate Currency, and, in such case, in such Alternate Currency), in the same manner as provided in Section 2.5 hereof with respect to Revolving Loans. Each Lender is hereby authorized to record on its records such Lender’s pro rata share of the amounts paid and not reimbursed on the Letters of Credit. In addition, each Lender agrees to risk participate in the Existing Letters of Credit as provided in subsection (vi) below.

(vi) Existing Letters of Credit. Schedule 2.2 hereto contains a description of all letters of credit outstanding on, and to continue in effect after, the Closing Date. Each such letter of credit issued by a bank that is or becomes a Lender under this Agreement on the Closing Date (each, an “Existing Letter of Credit”) shall constitute a “Letter of Credit” for all purposes of this Agreement, issued, for purposes of Section 2.2(b)(vi) hereof, on the Closing Date. Borrowers, Agent and the applicable Lenders hereby agree that, from and after such date, the terms of this Agreement shall apply to the Existing Letters of Credit, superseding any other agreement theretofore applicable to them to the extent inconsistent with the terms hereof. Notwithstanding anything to the contrary in any reimbursement agreement applicable to the Existing Letters of Credit, the fees payable in connection with each Existing Letter of Credit to be shared with the Lenders shall accrue from the Closing Date at the rate provided in Section 2.2(b)(iii) hereof.

(i) Generally. Subject to the terms and conditions of this Agreement, during the Commitment Period, the Swing Line Lender shall make a Swing Loan or Swing Loans to US Borrowers in such amount or amounts as Administrative Borrower, through an Authorized Officer, may from time to time request; provided that Administrative Borrower shall not request any Swing Loan if, after giving effect thereto, (A) the Revolving Credit Exposure would exceed the Total Commitment Amount, or (B) the Swing Line Exposure would exceed the Swing Line Commitment. Each Swing Loan shall be due and payable on the Swing Loan Maturity Date applicable thereto. US Borrowers shall not request that more than two Swing Loans be outstanding at any time. Each Swing Loan shall be made in Dollars.

(ii) Refunding of Swing Loans. If the Swing Line Lender so elects, by giving notice to Administrative Borrower and the Lenders, US Borrowers agree that the Swing Line Lender shall have the right, in its sole discretion, to require that any Swing Loan be refinanced as a Revolving Loan. Such Revolving Loan shall be a Base Rate Loan unless otherwise requested by and available to US Borrowers hereunder. Upon receipt of such notice by US Borrowers and the Lenders, US Borrowers shall be deemed, on such day, to have requested a Revolving Loan in the principal amount of the Swing Loan in accordance with subsection (a) of this Section 2.2 and Section 2.5 hereof (other than the requirement set forth in Section 2.5(d) hereof). Such Revolving Loan shall be evidenced by the Revolving Credit Notes. Each Lender agrees to make a Revolving Loan on the date of such notice, subject to no conditions precedent whatsoever. Each Lender acknowledges and agrees that such Lender’s obligation to make a Revolving Loan pursuant to subsection (a) of this Section when required by this subsection (ii) is absolute and unconditional and shall not be affected by any circumstance whatsoever, including, without limitation, the occurrence and continuance of a Default or Event of Default, and that its payment to Agent, for the account of the Swing Line Lender, of the proceeds of such Revolving Loan shall be made without any offset, abatement, recoupment, counterclaim, withholding or reduction whatsoever and whether or not such Lender’s Revolving Credit Commitment shall have been reduced or terminated. US Borrowers irrevocably authorize and instruct Agent to apply the proceeds of any borrowing pursuant to this subsection (ii) to repay in full such Swing Loan. Each Lender is hereby authorized to record on its records relating to its US Borrower Revolving Credit Note such Lender’s pro rata share of the amounts paid to refund such Swing Loan.

(iii) Participation in Swing Loans. If, for any reason, Agent is unable to or, in the opinion of Agent, it is impracticable to, convert any Swing Loan to a Revolving Loan pursuant to the preceding subsection (ii), then o n any day that a Swing Loan is outstanding (whether before or after the maturity thereof), Agent shall have the right to request that each Lender purchase a participation in such Swing Loan, and Agent shall promptly notify each Lender thereof (by facsimile or telephone, confirmed in writing). Upon such notice, but without further action, the Swing Line Lender hereby agrees to grant to each Lender, and each Lender hereby agrees to acquire from the Swing Line Lender, an undivided participation interest in such Swing Loan in an amount equal to

such Lender’s Commitment Percentage of the principal amount of such Swing Loan. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to Agent, for the benefit of the Swing Line Lender, such Lender’s ratable share of such Swing Loan (determined in accordance with such Lender’s Commitment Percentage). Each Lender acknowledges and agrees that its obligation to acquire participations in Swing Loans pursuant to this subsection (iii) is absolute and unconditional and shall not be affected by any circumstance whatsoever, including, without limitation, the occurrence and continuance of a Default or an Event of Default, and that each such payment shall be made without any offset, abatement, recoupment, counterclaim, withholding or reduction whatsoever and whether or not such Lender’s Revolving Credit Commitment shall have been reduced or terminated. Each Lender shall comply with its obligation under this subsection (iii) by wire transfer of immediately available funds, in the same manner as provided in Section 2.5 hereof with respect to Revolving Loans to be made by such Lender.

Section 2.3. Interest.

(a) Revolving Loans.

(i) Base Rate Loan. The appropriate Borrower or Borrowers shall pay interest on the unpaid principal amount of a Base Rate Loan outstanding from time to time from the date thereof until paid at the Base Rate from time to time in effect. Interest on such Base Rate Loan shall be payable, commencing February 28, 2005, and on each Regularly Scheduled Payment Date thereafter and at the maturity thereof.

(ii) LIBOR Fixed Rate Loans. The appropriate Borrower or Borrowers shall pay interest on the unpaid principal amount of each LIBOR Fixed Rate Loan outstanding from time to time, fixed in advance on the first day of the Interest Period applicable thereto through the last day of the Interest Period applicable thereto (but subject to changes in the Applicable Margin), at the Derived LIBOR Fixed Rate. Interest on such LIBOR Fixed Rate Loan shall be payable on each Interest Adjustment Date with respect to an Interest Period (provided that if an Interest Period shall exceed three months, the interest must be paid every three months, commencing three months from the beginning of such Interest Period).

(b) Swing Loans. US Borrowers shall pay interest to Agent, for the sole benefit of the Swing Line Lender (and any Lender that shall have purchased a participation in such Swing Loan), on the unpaid principal amount of each Swing Loan outstanding from time to time from the date thereof until paid at the Derived Swing Loan Rate applicable to such Swing Loan. Interest on each Swing Loan shall be payable on the Swing Loan Maturity Date applicable thereto. Each Swing Loan shall bear interest for a minimum of one day.

(c) Default Rate. Anything herein to the contrary notwithstanding, if an Event of Default shall occur hereunder and during the continuance thereof, upon the election of the Required Lenders (i) the principal of each Loan and the unpaid interest thereon shall bear

interest, until paid, at the Default Rate, (ii) the fee for the aggregate undrawn face amount of all issued and outstanding Letters of Credit shall be increased by two percent (2%) in excess of the rate otherwise applicable thereto, and (iii) in the case of any other amount due from Borrowers hereunder or under any other Loan Document, such amount shall bear interest at the Default Rate; provided that, during an Event of Default under Section 7.13 hereof, the applicable Default Rate shall apply without any election or action on the part of Agent or any Lender.

(d) Limitation on Interest. In no event shall the rate of interest hereunder exceed the maximum rate allowable by law. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”). If Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the applicable Borrower. In determining whether the interest contracted for, charged, or received by Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable law, (i) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations, so long as the foregoing does not adversely affect a Borrower.

Section 2.4. Evidence of Indebtedness.

(a) US Borrower Revolving Loans. The obligation of US Borrowers to repay the Base Rate Loans and LIBOR Fixed Rate Loans made by each Lender and to pay interest thereon shall be evidenced by a US Borrower Revolving Credit Note of US Borrowers in the form of the attached Exhibit A, payable to the order of such Lender in the principal amount of its Revolving Credit Commitment or, if less, the aggregate unpaid principal amount of Revolving Loans made by such Lender.

(b) Foreign Borrower Revolving Loans. The obligation of each Foreign Borrower to repay the Base Rate Loans and LIBOR Fixed Rate Loans made by each Lender and to pay interest thereon shall be evidenced by a Foreign Borrower Revolving Credit Note of such Foreign Borrower in the form of the attached Exhibit B, payable to the order of such Lender in the principal amount of its Revolving Credit Commitment or, if less, the aggregate unpaid principal amount of Revolving Loans made to such Foreign Borrower by such Lender.

(c) Swing Loan. The obligation of US Borrowers to repay the Swing Loans and to pay interest thereon shall be evidenced by a Swing Line Note of US Borrowers in the form of the attached Exhibit C, and payable to the order of the Swing Line Lender in the principal amount of the Swing Line Commitment, or, if less, the aggregate unpaid principal amount of Swing Loans made by the Swing Line Lender.

Section 2.5. Notice of Credit Event; Funding of Loans.

(a) Notice of Credit Event. Administrative Borrower, through an Authorized Officer, shall provide to Agent a Notice of Loan prior to (i) 11:00 A.M. (Mountain time) on the proposed date of borrowing or conversion of any Base Rate Loan, (ii) 11:00 A.M. (Mountain time) three Business Days prior to the proposed date of borrowing, conversion or continuation of any LIBOR Fixed Rate Loan, and (iii) 2:00 P.M. (Mountain time) on the proposed date of borrowing of any Swing Loan; provided, however, that an Authorized Officer of Administrative Borrower may verbally request a Loan, so long as a Notice of Loan is received by the end of the same Business Day, and, if Agent or any Lender provides funds or initiates funding based upon such verbal request, Administrative Borrower shall bear the risk with respect to any information regarding such funding that is later determined to have been incorrect.

(b) Funding of Loans. Agent shall notify each Lender of the date, amount, type of currency and Interest Period (if applicable) promptly upon the receipt of a Notice of Loan, and, in any event, by 2:00 P.M. (Mountain time) on the date such Notice of Loan is received. On the date that the Credit Event set forth in such Notice of Loan is to occur, each such Lender shall provide to Agent, not later than 3:00 P.M. (Mountain time), the amount in Dollars, or, with respect to an Alternate Currency, in the applicable Alternate Currency, in federal or other immediately available funds, required of it. If Agent shall elect to advance the proceeds of such Loan prior to receiving funds from such Lender, Agent shall have the right, upon prior notice to Administrative Borrower, to debit any account of any US Borrower or otherwise receive such amount from US Borrowers or the appropriate Foreign Borrower, on demand, in the event that such Lender shall fail to reimburse Agent in accordance with this subsection. Agent shall also have the right to receive interest from such Lender at the Federal Funds Effective Rate in the event that such Lender shall fail to provide its portion of the Loan on the date requested and Agent shall elect to provide such funds.

(c) Conversion of Loans. At the request of Administrative Borrower to Agent, subject to the notice and other provisions of this Section 2.5, the Lenders shall convert a Base Rate Loan to one or more Eurodollar Loans at any time and shall convert a Eurodollar Loan to a Base Rate Loan on any Interest Adjustment Date applicable thereto. Swing Loans may be converted by the Swing Line Lender to Revolving Loans in accordance with Section 2.2(c)(ii) hereof. No Alternate Currency Loan may be converted to a Base Rate Loan or Eurodollar Loan and no Base Rate Loan or Eurodollar Loan may be converted to an Alternate Currency Loan.

(d) Minimum Amount. Each request for:

(i) a Base Rate Loan shall be in an amount of not less than Three Million Dollars ($3,000,000), increased by increments of One Million Dollars ($1,000,000);

(ii) a LIBOR Fixed Rate Loan shall be in an amount (or, with respect to an Alternate Currency Loan, the Dollar Equivalent (or, in the discretion of Agent, such approximately comparable amount as shall result in a rounded number)) of not less than Three Million Dollars ($3,000,000), increased by increments of One Million Dollars ($1,000,000) (or, with respect to an Alternate Currency Loan, the Dollar Equivalent (or,

in the discretion of Agent, such approximately comparable amount as shall result in a rounded number)); and

(iii) a Swing Loan shall be in an amount of not less than Five Hundred Thousand Dollars ($500,000).

(e) Interest Periods. At no time shall Borrowers request that LIBOR Fixed Rate Loans be outstanding for more than twelve different Interest Periods.

Section 2.6. Payment on Loans and Other Obligations.

(a) Payments Generally. Each payment made hereunder by a Credit Party shall be made without any offset, abatement, recoupment, counterclaim, withholding or reduction whatsoever.

(b) Payments in Alternate Currency to Agent or Lenders. With respect to any Alternate Currency Loan or any Alternate Currency Letter of Credit, all payments (including prepayments) to any Lender of the principal of or interest on such Alternate Currency Loan or Alternate Currency Letter of Credit shall be made in the same Alternate Currency as the original Loan or Letter of Credit. All such payments shall be remitted by Borrowers to Agent, at the address of Agent for notices referred to in Section 10.4 hereof, (or at such other office or account as designated in writing by Agent to Administrative Borrower) for the account of the Lenders (or the Fronting Lender, as appropriate) not later than 11:00 A.M. (Mountain time) on the due date thereof in same day funds. Any payments received by Agent after 11:00 A.M. (Mountain time) shall be deemed to have been made and received on the next Business Day.

(c) Payments in Dollars to Agent or Lenders. With respect to (i) any Loan (other than an Alternate Currency Loan), or (ii) any other payment to Agent and the Lenders that shall not be covered by subsection (b) above, all such payments (including prepayments) to Agent of the principal of or interest on such Loan or other payment, including but not limited to principal, interest, fees or any other amount owed by any Borrower under this Agreement, shall be made in Dollars. All payments described in this subsection (c) shall be remitted to Agent, at the address of Agent for notices referred to in Section 10.4 hereof, for the account of the Lenders (or the Fronting Lender or the Swing Line Lender, as appropriate) not later than 11:00 A.M. (Mountain time) on the due date thereof in immediately available funds. Any such payments received by Agent after 11:00 A.M. (Mountain time) shall be deemed to have been made and received on the next Business Day.

(d) Payments to Lenders from Agent. Upon Agent’s receipt of payments hereunder, Agent shall immediately distribute to the Lenders (except with respect to Swing Loans, which shall be paid to the Swing Line Lender or, with respect to Letters of Credit, certain of which payments shall be made to the Fronting Lender) their respective ratable shares, if any, of the amount of principal, interest, and facility and other fees received by Agent for the account of such Lender. Payments received by Agent in Dollars shall be delivered to the Lenders in Dollars in immediately available funds. Payments received by Agent in any Alternate Currency shall be delivered to the Lenders in such Alternate Currency in same day funds. Each Lender shall

record any principal, interest or other payment, the principal amounts of Base Rate Loans, LIBOR Fixed Rate Loans, Swing Loans and Letters of Credit, the type of currency for each Loan, all prepayments and the applicable dates, including Interest Periods, with respect to the Loans made, and payments received by such Lender, by such method as such Lender may generally employ; provided, however, that failure to make any such entry shall in no way detract from the obligations of Borrowers under this Agreement or any Note. The aggregate unpaid amount of Loans, types of Loans, Interest Periods and similar information with respect to the Loans and Letters of Credit set forth on the records of Agent shall be rebuttably presumptive evidence with respect to such information, including the amounts of principal, interest and fees owing to each Lender.

(e) Timing of Payments. Whenever any payment to be made hereunder, including, without limitation, any payment to be made on any Loan, shall be stated to be due on a day that is not a Business Day, such payment shall be made on the next Business Day and such extension of time shall in each case be included in the computation of the interest payable on such Loan; provided, however, that, with respect to any LIBOR Fixed Rate Loan, if the next Business Day shall fall in the succeeding calendar month, such payment shall be made on the preceding Business Day and the relevant Interest Period shall be adjusted accordingly.

Section 2.7. Prepayment.

(a) Right to Prepay. Borrowers shall have the right at any time or from time to time to prepay, on a pro rata basis for all of the Lenders (except with respect to Swing Loans, which shall be paid to the Swing Line Lender), all or any part of the principal amount of the Loans, as designated by Borrowers. Such payment shall include interest accrued on the amount so prepaid to the date of such prepayment and any amount payable under Article III hereof with respect to the amount being prepaid. Prepayments of Base Rate Loans shall be without any premium or penalty, other than any prepayment fees, penalties or other charges that may be contained in any Hedge Agreement.

(b) Notice of Prepayment. Administrative Borrower shall give Agent notice of prepayment of a Base Rate Loan or Swing Loan not later than 1:00 P.M. (Mountain time) one Business Day before the Business Day on which such prepayment is to be made and written notice of the prepayment of any LIBOR Fixed Rate Loan not later than 1:00 P.M. (Mountain time) three Business Days before the Business Day on which such prepayment is to be made.

(c) Minimum Amount. Each prepayment of a LIBOR Fixed Rate Loan shall be in the principal amount of not less than One Million Dollars ($1,000,000), (or, with respect to an Alternate Currency Loan, the Dollar Equivalent (rounded to a comparable amount of such amount)) or, with respect to a Swing Loan, the principal balance of such Swing Loan, except in the case of a mandatory payment pursuant to Section 2.11 or Article III hereof.

Section 2.8. Facility and Other Fees.

(a) Facility Fee. US Borrowers shall pay to Agent, for the ratable account of the Lenders, as a consideration for the Commitment, a facility fee from the Closing Date to and

including the last day of the Commitment Period, payable quarterly, at a rate per annum equal to (i) the Applicable Facility Fee Rate in effect on the payment date, multiplied by (ii) the average daily Total Commitment Amount in effect during such quarter. The facility fee shall be payable quarterly in arrears, on February 28, 2005 and continuing on each Regularly Scheduled Payment Date thereafter, and on the last day of the Commitment Period.

(b) Agent Fee. US Borrowers shall pay to Agent, for its sole benefit, the fees set forth in the Agent Fee Letter.

Section 2.9. Modifications to Commitment.

(a) Optional Reduction of Commitment. Borrowers may at any time and from time to time permanently reduce in whole or ratably in part the Commitment hereunder to an amount not less than the then existing Revolving Credit Exposure, by Administrative Borrower giving Agent not fewer than three Business Days’ written notice of such reduction, provided that any such partial reduction shall be in an aggregate amount, for all of the Lenders, of not less than Five Million Dollars ($5,000,000), increased by increments of One Million Dollars ($1,000,000). Agent shall promptly notify each Lender of the date of each such reduction and such Lender’s proportionate share thereof. After each such reduction, the facility fees payable hereunder shall be calculated upon the Total Commitment Amount as so reduced. If Borrowers reduce in whole the Commitment on the effective date of such reduction (the appropriate Borrowers having prepaid in full the unpaid principal balance, if any, of the Loans, together with all interest and facility and other fees accrued and unpaid and provided that no Letter of Credit Exposure or Swing Line Exposure shall exist), all of the Notes shall be delivered to Agent marked “Canceled” and Agent shall redeliver such Notes to Administrative Borrower. Any partial reduction in the Total Commitment Amount shall be effective during the remainder of the Commitment Period.

(b) Increase in Commitment. At any time during the Commitment Increase Period, Administrative Borrower may request that Agent increase the Total Commitment Amount from the Closing Commitment Amount up to the Maximum Commitment Amount by either, at the option of Administrative Borrower, (i) increasing, for one or more Lenders, with their prior written consent, their respective Revolving Credit Commitments, or (ii) including one or more Additional Lenders, acceptable to Administrative Borrower, each with a new Revolving Credit Commitment, as a party to this Agreement (collectively, the “Additional Commitment”); provided, however, that existing Lenders shall be given the first opportunity to provide the Additional Commitments. During the Commitment Increase Period, the Lenders agree that Agent, in its sole discretion, may permit one or more Additional Commitments upon satisfaction of the following requirements: (A) each Additional Lender, if any, shall execute an Additional Lender Assumption Agreement, (B) Agent shall provide to each Lender a revised Schedule 1 to this Agreement, including revised Commitment Percentages for each of the Lenders, if appropriate, at least three Business Days prior to the effectiveness of such Additional Commitments (each an “Additional Lender Assumption Effective Date”), and (C) US Borrowers and, as appropriate, each Foreign Borrower shall execute and deliver to Agent and the Lenders such replacement or additional Revolving Credit Notes as shall be required by Agent. The Lenders hereby authorize Agent to execute each Additional Lender Assumption Agreement on

behalf of the Lenders. On each Additional Lender Assumption Effective Date, the Lenders shall make adjustments among themselves with respect to the Revolving Loans then outstanding and amounts of principal, interest, facility fees and other amounts paid or payable with respect thereto as shall be necessary, in the opinion of Agent, in order to reallocate among such Lenders such outstanding amounts, based on the revised Commitment Percentages and to otherwise carry out fully the intent and terms of this Section 2.9(b). Borrowers shall not request any increase in the Commitment pursuant to this Section 2.9(b) if a Default or an Event of Default shall then exist, or immediately after giving effect to any such increase would exist.

Section 2.10. Computation of Interest and Fees. With the exception of Base Rate Loans, interest on Loans and facility and other fees and charges hereunder shall be computed on the basis of a year having three hundred sixty (360) days and calculated for the actual number of days elapsed. With respect to Base Rate Loans, interest shall be computed on the basis of a year having three hundred sixty-five (365) days or three hundred sixty-six (366) days, as the case may be, and calculated for the actual number of days elapsed.

Section 2.11. Mandatory Payment.

(a) Revolving Credit Exposure. If, at any time, the Revolving Credit Exposure shall exceed the Total Commitment Amount as then in effect, US Borrowers (and the appropriate Foreign Borrowers) shall, as promptly as practicable, but in no event later than the next Business Day, prepay an aggregate principal amount of the Loans sufficient to bring the Revolving Credit Exposure within the Total Commitment Amount.

(b) Swing Line Exposure. If, at any time, the Swing Line Exposure shall exceed the Swing Line Commitment, US Borrowers shall, as promptly as practicable, but in no event later than the next Business Day, prepay an aggregate principal amount of the Swing Loans sufficient to bring the Swing Line Exposure within the Swing Line Commitment.

(c) Mandatory Payments Generally. Unless otherwise designated by Borrowers, each prepayment pursuant to Section 2.11(a) hereof shall be applied in the following order (i) first, to the outstanding Base Rate Loans, and (ii) second, to the outstanding LIBOR Fixed Rate Loans, provided that if the outstanding principal amount of any LIBOR Fixed Rate Loan shall be reduced to an amount less than the minimum amount set forth in Section 2.5(d) hereof as a result of such prepayment, then such LIBOR Fixed Rate Loan shall be converted into a Base Rate Loan on the date of such prepayment. Any prepayment of a LIBOR Fixed Rate Loan or Swing Loan pursuant to this Section 2.11 shall be subject to the prepayment provisions set forth in Article III hereof.

Section 2.12. Liability of Borrowers.

(a) Joint and Several Liability. Each US Borrower acknowledges and agrees that Agent and the Lenders are entering into this Agreement at the request of each US Borrower and with the understanding that each US Borrower is and shall remain fully liable, jointly and severally, for payment in full of the Obligations. Each US Borrower agrees that it is receiving or will receive a direct pecuniary benefit for each Loan made or Letter of Credit issued hereunder.

(b) Appointment of Administrative Borrower. Each Borrower hereby irrevocably appoints IHS as the borrowing agent and attorney-in- fact for all Borrowers (“Administrative Borrower”) which appointment shall remain in full force and effect unless and until Agent shall have received prior written notice signed by each Borrower that such appointment has been revoked and that another Borrower has been appointed Administrative Borrower. Each Borrower hereby irrevocably appoints and authorizes Administrative Borrower to (i) provide Agent with all notices with respect to Loans and Letters of Credit obtained for the benefit of any Borrower and all other notices and instructions under this Agreement, (ii) take such action as Administrative Borrower deems appropriate on its behalf to obtain Loans and Letters of Credit, and (iii) exercise such other powers as are reasonably incidental thereto to carry out the purposes of this Agreement.

(c) Maximum Liability of Each Borrower. Anything in this Agreement or any other Loan Document to the contrary notwithstanding, in no event shall the maximum liability of any Subsidiary Borrower exceed the maximum amount that (after giving effect to the incurring of the obligations hereunder and to any rights to contribution of such Subsidiary Borrower from other Affiliates of such Subsidiary Borrower) would not render the rights to payment of Agent and the Lenders hereunder void, voidable or avoidable under any applicable fraudulent transfer law.

(d) Waivers of Each Borrower. In the event that any obligation of any Borrower under this Agreement is deemed to be an agreement by such Borrower to answer for the debt or default of another Credit Party or as a hypothecation of property as security therefore, each Borrower represents and warrants that (i) no representation has been made to such Borrower as to the creditworthiness of such other Credit Party, and (ii) such Borrower has established adequate means of obtaining from such other Credit Party on a continuing basis, financial or other information pertaining to such other Credit Party’s financial condition. Each Borrower expressly waives, except as expressly required under this Agreement, diligence, demand, presentment, protest and notice of every kind and nature whatsoever, consents to the taking by Agent and the Lenders of any additional security, if any, of another Credit Party for the obligations secured hereby, or the alteration or release in any manner of any security, if any, of another Credit Party now or hereafter held in connection with the Obligations, and consents that Agent, the Lenders and any other Credit Party may deal with each other in connection with such obligations or otherwise, or alter any contracts now or hereafter existing between them, in any manner whatsoever, including without limitation the renewal, extension, acceleration or changes in time for payment of any such obligations or in the terms or conditions of any security held. Agent and the Lenders are hereby expressly given the right, at their option, to proceed in the enforcement of any of the Obligations independently of any other remedy or security they may at any time hold in connection with such obligations secured and it shall not be necessary for Agent and the Lenders to proceed upon or against or exhaust any other security or remedy before proceeding to enforce their rights against such Borrower. Each Borrower further subordinates any right of subrogation, reimbursement, exoneration, contribution, indemnification, setoff or other recourse in respect of sums paid to Agent and the Lenders by any other Credit Party.

(e) Liability of Foreign Borrowers. Anything herein to the contrary notwithstanding, no Foreign Borrower shall at any time be liable for the Indebtedness of US Borrowers under this Agreement.

Section 2.13. Addition of Foreign Borrowers or Foreign Guarantors.

(a) Addition of Foreign Borrower. At the request of Administrative Borrower, a Foreign Subsidiary of IHS that shall not then be a Foreign Borrower may become a Foreign Borrower hereunder, provided that all of the following requirements shall have been met to the satisfaction of Agent: (i) Administrative Borrower shall have provided to Agent a written request that such Foreign Subsidiary be designated as a Foreign Borrower pursuant to the terms of this Agreement, which request shall specify the amount of Revolving Loans and Letters of Credit requested to be made available to such Foreign Subsidiary (the “Requested Availability”); (ii) Agent shall have approved the amount of the Requested Availability or otherwise agreed with Administrative Borrower as to the revised amount of availability, and, upon such approval or reaching such agreement, Agent is hereby authorized to record such amount on Schedule 4 hereto as the “Additional Foreign Borrower Maximum Amount” with respect to such Foreign Subsidiary; (iii) such Foreign Subsidiary shall be a Wholly-Owned Subsidiary of IHS; (iv) IHS and each Domestic Guarantor of Payment shall have guaranteed the obligations of such Foreign Subsidiary under this Agreement pursuant to the terms of a Guaranty of Payment; (v) such Foreign Subsidiary shall have executed a Foreign Borrower Assumption Agreement and Foreign Borrower Revolving Credit Notes, and any other Foreign Subsidiary that Agent and Administrative Borrower agree shall become a Foreign Guarantor of Payment with respect to such Foreign Subsidiary, shall have executed a Guaranty of Payment with respect to the obligations of such Foreign Subsidiary (provided that there shall be no adverse tax consequences or adverse legal impact); and (vi) IHS and such Foreign Subsidiary that shall become a Foreign Guarantor of Payment shall have provided to Agent such corporate governance and authorization documents and an opinion of counsel and any other items as may be deemed necessary or advisable by Agent.

(b) Addition of Foreign Guarantor of Payment. At the request of Administrative Borrower, a Foreign Subsidiary of IHS that shall not then be a Foreign Guarantor of Payment may become a Foreign Guarantor of Payment hereunder, provided that all of the following requirements shall have been met to the satisfaction of Agent: (i) Administrative Borrower shall have provided to Agent a written request that such Foreign Subsidiary be designated as a Foreign Guarantor of Payment pursuant to the terms of this Agreement, which request shall specify the Requested Availability for such Foreign Subsidiary; (ii) Agent shall have approved the amount of the Requested Availability or otherwise agreed with Administrative Borrower as to the revised amount of availability, and, upon such approval or reaching such agreement, Agent is hereby authorized to record such amount on Schedule 4 hereto as the “Additional Foreign Guarantor Maximum Amount” with respect to such Foreign Subsidiary; (ii) such Foreign Subsidiary shall be a Wholly-Owned Subsidiary of IHS; (iii) such Foreign Subsidiary shall have executed a Guaranty of Payment with respect to the obligations of one or more Foreign Borrowers as may be required by Agent (provided that there shall be no adverse tax consequences or adverse legal impact); and (iii) such Foreign Subsidiary that shall become a Foreign Guarantor of Payment

shall have provided to Agent such corporate governance and authorization documents and an opinion of counsel and any other items as may be deemed necessary or advisable by Agent.

(c) Additional Credit Party Bound by Provisions. Upon satisfaction by Administrative Borrower and any such Foreign Subsidiary of the requirements set forth in subsections (a) and (b) above, Agent shall promptly notify Administrative Borrower and the Lenders, whereupon such Foreign Subsidiary shall be designated a “Foreign Borrower” or “Foreign Guarantor of Payment”, as applicable, pursuant to the terms and conditions of this Agreement, and such Foreign Subsidiary shall become bound by all representations, warranties, covenants, provisions and conditions of this Agreement and each other Loan Document applicable to the Foreign Borrowers or Foreign Guarantors of Payment, as the case may be, as if such Foreign Borrower or Foreign Guarantor had been the original party making such representations, warranties and covenants.

(d) Alternative Structures. Agent, the Lenders and Borrowers agree that if the addition of a Foreign Borrower or Foreign Guarantor of Payment pursuant to this Section would result in a requirement by such Foreign Borrower or Foreign Guarantor of Payment to pay to any Lenders additional amounts pursuant to Section 3.2 hereof, then Agent, the Lenders and Borrowers agree to use reasonable efforts to designate a different lending office or otherwise propose an alternate structure that would avoid the need for, or reduce the amount of, such additional amounts so long as the same would not, in the judgment of Agent and the Lenders, be otherwise disadvantageous to Agent and the Lenders.

Section 2.14. Extension of Commitment. Contemporaneously with the delivery of the financial statements required pursuant to Section 5.3(b) hereof (beginning with the financial statements for the fiscal year of IHS ending November 30, 2005), Borrowers may deliver a Request for Extension, requesting that the Lenders extend the maturity of the Commitment for an additional year. Each such extension shall require the unanimous written consent of all of the Lenders and shall be upon such terms and conditions as may be agreed to by Agent, Borrowers and the Lenders. Borrowers shall pay any attorneys’ fees or other expenses of Agent in connection with the documentation of any such extension, as well as such other fees as may be agreed upon between Borrowers and Agent.

ARTICLE III. ADDITIONAL PROVISIONS RELATING TO
LIBOR FIXED RATE LOANS; INCREASED CAPITAL; TAXES

Section 3.1. Requirements of Law.

(a) If, after the Closing Date, (i) the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or (ii) the compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority:

(A) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit or any LIBOR Fixed Rate Loan made by it, or

change the basis of taxation of payments to such Lender in respect thereof (except for Taxes and Excluded Taxes which are governed by Section 3.2 hereof);

(B) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the Eurodollar Rate or the Alternate Currency Rate; or

and the result of any of the foregoing is to increase the cost to such Lender of making, converting into, continuing or maintaining LIBOR Fixed Rate Loans or issuing or participating in Letters of Credit, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, US Borrowers (and any Foreign Borrower to which such Loan was made) shall pay to such Lender, promptly after receipt of a written request therefor, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this subsection (a), such Lender shall promptly notify Administrative Borrower (with a copy to Agent) of the event by reason of which it has become so entitled.

(b) If any Lender shall have determined that, after the Closing Date, the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority shall have the effect of reducing the rate of return on such Lender’s or such corporation’s capital as a consequence of its obligations hereunder, or under or in respect of any Letter of Credit, to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration the policies of such Lender or corporation with respect to capital adequacy), then from time to time, upon submission by such Lender to Administrative Borrower (with a copy to Agent) of a written request therefor (which shall include the method for calculating such amount), US Borrowers (and any Foreign Borrower to which such Loan was made) shall promptly pay or cause to be paid to such Lender such additional amount or amounts as will compensate such Lender for such reduction.

(c) A certificate as to any additional amounts payable pursuant to this Section 3.1 submitted by any Lender to Administrative Borrower (with a copy to Agent) shall be conclusive absent manifest error. In determining any such additional amounts, such Lender may use any method of averaging and attribution that it (in its sole discretion) shall deem applicable. The obligations of Borrowers pursuant to this Section 3.1 shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

Section 3.2. Taxes.

(a) All payments made by any Credit Party under any Loan Document shall be made free and clear of, and without deduction or withholding for or on account of any Taxes or Other Taxes. If any Taxes or Other Taxes are required to be deducted or withheld from any amounts payable to Agent or any Lender hereunder, the amounts so payable to Agent or such Lender shall be increased to the extent necessary to yield to Agent or such Lender (after deducting, withholding and payment of all Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in the Loan Documents.

(b) In addition, the Credit Parties shall pay Taxes and Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Whenever any Taxes or Other Taxes are required to be withheld and paid by a Credit Party, such Credit Party shall timely withhold and pay such taxes to the relevant Governmental Authorities. As promptly as possible thereafter, such Credit Party shall send to Agent for its own account or for the account of the relevant Lender, as the case may be, a certified copy of an original official receipt received by such Credit Party showing payment thereof. If such Credit Party shall fail to pay any Taxes or Other Taxes when due to the appropriate Governmental Authority or fails to remit to Agent the required receipts or other required documentary evidence, US Borrowers and such Credit Party shall indemnify Agent and the Lenders on demand for any incremental Taxes or Other Taxes paid or payable by Agent or such Lender as a result of any such failure.

(d) If any Lender shall be so indemnified by a Credit Party, such Lender shall use reasonable efforts to obtain the benefits of any refund, deduction or credit for any taxes or other amounts with respect to the amount paid by such Credit Party and shall reimburse such Credit Party to the extent, but only to the extent, that such Lender shall receive a refund with respect to the amount paid by such Credit Party or an effective net reduction in taxes or other governmental charges (including any taxes imposed on or measured by the total net income of such Lender) of the United States or any state or subdivision or any other Governmental Authority thereof by virtue of any such deduction or credit, after first giving effect to all other deductions and credits otherwise available to such Lender. If, at the time any audit of such Lender’s income tax return is completed, such Lender determines, based on such audit, that it shall not have been entitled to the full amount of any refund reimbursed to such Credit Party as aforesaid or that its net income taxes shall not have been reduced by a credit or deduction for the full amount reimbursed to such Credit Party as aforesaid, such Credit Party, upon request of such Lender, shall promptly pay to such Lender the amount so refunded to which such Lender shall not have been so entitled, or the amount by which the net income taxes of such Lender shall not have been so reduced, as the case may be.

(e) Each Lender that is not (i) a citizen or resident of the United States of America, (ii) a corporation, partnership or other entity created or organized in or under the laws of the United States of America (or any jurisdiction thereof), or (iii) an estate or trust that is subject to federal income taxation regardless of the source of its income (any such Person, a “Non-U.S. Lender”) shall deliver to Administrative Borrower and Agent two copies of either U.S. Internal

Revenue Service Form W-8BEN or Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest”, a statement with respect to such interest and a Form W-8BEN, or any subsequent versions thereof or successors thereto, properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by Credit Parties under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement or such other Loan Document. In addition, each Non-U.S. Lender shall deliver such forms or appropriate replacements promptly upon the obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender. Each Non-U.S. Lender shall promptly notify Administrative Borrower at any time it determines that such Lender is no longer in a position to provide any previously delivered certificate to Administrative Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose). Notwithstanding any other provision of this subsection (e), a Non-U.S. Lender shall not be required to deliver any form pursuant to this subsection (e) that such Non-U.S. Lender is not legally able to deliver.

(f) The agreements in this Section 3.2 shall survive the termination of the Loan Documents and the payment of the Loans and all other amounts payable hereunder.

Section 3.3. Funding Losses. US Borrowers (and any appropriate Foreign Borrower) agree to indemnify each Lender, promptly after receipt of a written request therefor, and to hold each Lender harmless from, any loss or expense that such Lender may sustain or incur as a consequence of (a) default by a Borrower in making a borrowing of, conversion into or continuation of LIBOR Fixed Rate Loans after such Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by a Borrower in making any prepayment of or conversion from LIBOR Fixed Rate Loans after such Borrower has given a notice thereof in accordance with the provisions of this Agreement, (c) the making of a prepayment of a LIBOR Fixed Rate Loan on a day that is not the last day of an Interest Period applicable thereto, (d) any conversion of a LIBOR Fixed Rate Loan to a Base Rate Loan on a day that is not the last day of an Interest Period applicable thereto. Such indemnification shall be in an amount equal to the excess, if any, of (i) the amount of interest that would have accrued on the amounts so prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount b y placing such amount on deposit for a comparable period with leading banks in the appropriate London interbank market, along with any administration fee charged by such Lender. A certificate as to any amounts payable pursuant to this Section 3.3 submitted to Borrower (with a copy to Agent) by any Lender shall be conclusive absent manifest error. The obligations of Administrative Borrower pursuant to this Section 3.3 shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

Section 3.4. Eurodollar Rate or Alternate Currency Rate Lending Unlawful; Inability to Determine Rate.

(a) If any Lender shall determine (which determination shall, upon notice thereof to Administrative Borrower and Agent, be conclusive and binding on Borrowers) that, after the Closing Date, (i) the introduction of or any change in or in the interpretation of any law makes it unlawful, or (ii) any Governmental Authority asserts that it is unlawful, for such Lender to make or continue any Loan as, or to convert (if permitted pursuant to this Agreement) any Loan into, a LIBOR Fixed Rate Loan, the obligations of such Lender to make, continue or convert any such LIBOR Fixed Rate Loan shall, upon such determination, be suspended until such Lender shall notify Agent that the circumstances causing such suspension no longer exist, and all outstanding LIBOR Fixed Rate Loans payable to such Lender shall automatically convert (if conversion is permitted under this Agreement) into a Base Rate Loan, or be repaid (if no conversion is permitted) at the end of the then current Interest Periods with respect thereto or sooner, if required by law or such assertion.

(b) If Agent or the Required Lenders determine that for any reason adequate and reasonable means do not exist for determining the Eurodollar Rate or Alternate Currency Rate for any requested Interest Period with respect to a proposed LIBOR Fixed Rate Loan, or that the Eurodollar Rate or Alternate Currency Rate for any requested Interest Period with respect to a proposed LIBOR Fixed Rate Loan does not adequately and fairly reflect the cost to the Lenders of funding such Loan, Agent will promptly so notify Administrative Borrower and each Lender. Thereafter, the obligation of the Lenders to make or maintain such LIBOR Fixed Rate Loan shall be suspended until Agent (upon the instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, Administrative Borrower may revoke any pending request for a borrowing of, conversion to or continuation of such LIBOR Fixed Rate Loan or, failing that, will be deemed to have converted such request into a request for a borrowing of a Base Rate Loan in the amount specified therein.

Notwithstanding any contrary provision or inference herein or elsewhere:

Section 8.1. Optional Defaults. If any Event of Default referred to in Section 7.1, 7.2, 7.3, 7.4, 7.5, 7.6, 7.7, 7.8, 7.9, 7.10, 7.11 or 7.12 hereof shall occur, Agent may, with the consent of the Required Lenders, and shall, at the written request of the Required Lenders, give written notice to Borrowers to:

(a) terminate the Commitment, if not previously terminated, and, immediately upon such election, the obligations of the Lenders, and each thereof, to make any further Loan and the obligation of the Fronting Lender to issue any Letter of Credit immediately shall be terminated; and/or

(b) accelerate the maturity of all of the Obligations (if the Obligations are not already due and payable), whereupon all of the Obligations shall become and thereafter be immediately due and payable in full without any presentment or demand and without any further or other notice of any kind, all of which are hereby waived by each Borrower.

Section 8.2. Automatic Defaults. If any Event of Default referred to in Section 7.13 hereof shall occur:

(a) all of the Commitment shall automatically and immediately terminate, if not previously terminated, and no Lender thereafter shall be under any obligation to grant any further Loan, nor shall the Fronting Lender be obligated to issue any Letter of Credit; and

(b) the principal of and interest then outstanding on all of the Loans, and all of the other Obligations, shall thereupon become and thereafter be immediately due and payable in full (if the Obligations are not already due and payable), all without any presentment, demand or notice of any kind, which are hereby waived by each Borrower.

Section 8.3. Letters of Credit. If the maturity of the Obligations shall be accelerated pursuant to Section 8.1 or 8.2 hereof, US Borrowers shall immediately deposit with Agent, as

security for the obligations of US Borrowers and any Domestic Guarantor of Payment to reimburse Agent and the Lenders for any then outstanding Letters of Credit, cash equal to the sum of the aggregate undrawn balance of any then outstanding Letters of Credit. Agent and the Lenders are hereby authorized, at their option, to deduct any and all such amounts from any deposit balances then owing by any Lender (or any affiliate of such Lender, wherever located) to or for the credit or account of any US Borrower or Domestic Guarantor of Payment, as security for the obligations of US Borrowers and any Domestic Guarantor of Payment to reimburse Agent and the Lenders for any then outstanding Letters of Credit.

Section 8.4. Offsets. If there shall occur or exist any Event of Default referred to in Section 7.13 hereof or if the maturity of the Obligations is accelerated pursuant to Section 8.1 or 8.2 hereof, each Lender shall have the right at any time to set off against, and to appropriate and apply toward the payment of, any and all of the Obligations then owing by a Borrower or Guarantor of Payment to such Lender (including, without limitation, any participation purchased or to be purchased pursuant to Section 2.2 or 8.5 hereof), whether or not the same shall then have matured, any and all deposit (general or special) balances and all other Indebtedness then held or owing by such Lender (including, without limitation, by branches and agencies or any affiliate of such Lender, wherever located) to or for the credit or account of such Borrower or Guarantor of Payment, all without notice to or demand upon such Borrower or any other Person, all such notices and demands being hereby expressly waived by each Borrower.

Section 8.5. Equalization Provision. Each Lender agrees with the other Lenders that if it, at any time, shall obtain any Advantage over the other Lenders or any thereof in respect of the Obligations (except as to Swing Loans and Letters of Credit prior to Agent’s giving of notice to participate and except under Article III hereof), it shall purchase from the other Lenders, for cash and at par, such additional participation in the Obligations as shall be necessary to nullify the Advantage. If any such Advantage resulting in the purchase of an additional participation as aforesaid shall be recovered in whole or in part from the Lender receiving the Advantage, each such purchase shall be rescinded, and the purchase price restored (but without interest unless the Lender receiving the Advantage is required to pay interest on the Advantage to the Person recovering the Advantage from such Lender) ratably to the extent of the recovery. Each Lender further agrees with the other Lenders that if it at any time shall receive any payment for or on behalf of any Borrower on any Indebtedness owing by any Borrower to that Lender (whether by voluntary payment, by realization upon security, by reason of offset of any deposit or other indebtedness, by counterclaim or cross-action, by the enforcement of any right under any Loan Document, or otherwise) it will apply such payment first to any and all Obligations owing by such Borrower to that Lender (including, without limitation, any participation purchased or to be purchased pursuant to this Section 8.5 or any other Section of this Agreement). Each Credit Party agrees that any Lender so purchasing a participation from the other Lenders or any thereof pursuant to this Section 8.5 may exercise all of its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were a direct creditor of such Credit Party in the amount of such participation.

Section 8.6. Other Remedies. The remedies in this Article VIII are in addition to, not in limitation of, any other right, power, privilege, or remedy, either in law, in equity, or otherwise, to which the Lenders may be entitled. Agent shall exercise the rights under this Article VIII and

all other collection efforts on behalf of the Lenders and no Lender shall act independently with respect thereto, except as otherwise specifically set forth in this Agreement.

Section 9.7. Action by Agent. Subject to the other terms and conditions hereof, so long as Agent shall be entitled, pursuant to Section 9.6 hereof, to assume that no Default or Event of Default shall have occurred and be continuing, Agent shall be entitled to use its discretion with respect to exercising or refraining from exercising any rights that may be vested in it by, or with respect to taking or refraining from taking any action or actions that it may be able to take under or in respect of, this Agreement.

ARTICLE X. MISCELLANEOUS

Section 10.1. Lenders’ Independent Investigation. Each Lender, by its signature to this Agreement, acknowledges and agrees that Agent has made no representation or warranty, express or implied, with respect to the creditworthiness, financial condition, or any other condition of any Company or with respect to the statements contained in any information memorandum furnished in connection herewith or in any other oral or written communication between Agent and such Lender. Each Lender represents that it has made and shall continue to make its own independent investigation of the creditworthiness, financial condition and affairs of the Companies in connection with the extension of credit hereunder, and agrees that Agent has no duty or responsibility, either initially or on a continuing basis, to provide any Lender with any credit or other information with respect thereto (other than such notices as may be expressly required to be given by Agent to the Lenders hereunder), whether coming into its possession before the first Credit Event hereunder or at any time or times thereafter. Each Lender further represents that it has reviewed each of the Loan Documents.

Section 10.2. No Waiver; Cumulative Remedies. No omission or course of dealing on the part of Agent, any Lender or the holder of any Note in exercising any right, power or remedy hereunder or under any of the Loan Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy hereunder or under any of the Loan Documents.

date of interest or scheduled principal thereunder, or the payment date of facility or other fees or amounts payable hereunder, (c) any reduction in the rate of interest on the Loans (provided that the institution of the Default Rate and a subsequent removal o f the Default Rate shall not constitute a decrease in interest rate of this Section 10.3), or in any amount of scheduled principal or interest due on any Loan, or the payment of facility or other fees hereunder or any change in the manner of pro rata application of any payments made by Borrowers to the Lenders hereunder, (d) any change in any percentage voting requirement, voting rights, or the Required Lenders definition in this Agreement, (e) the release of any Borrower or Guarantor of Payment, except as specifically permitted hereunder, or (f) any amendment to this Section 10.3 or Section 8.5 hereof.

Section 10.4. Notices. All notices, requests, demands and other communications provided for hereunder shall be in writing and, if to a Borrower, mailed or delivered to it, addressed to it at the address specified on the signature pages of this Agreement (including a courtesy notice to Stephen Green, Esq., mailed or delivered to him, addressed to him at 1350 Avenue of the Americas, Suite 840, New York, New York 10019, provided that a failure to give such courtesy notice shall have no legal effect hereunder), if to a Lender, mailed or delivered to it, addressed to the address of such Lender specified on the signature pages of this Agreement, or, as to each party, at such other address as shall be designated by such party in a written notice to each of the other parties.

Each US Borrower, and each Foreign Borrower to the extent relating to the Loans and other credit extensions to such Foreign Borrower, agrees to defend, indemnify and hold harmless Agent and the Lenders (and their respective affiliates, officers, directors, attorneys, agents and employees) from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses (including reasonable attorneys’ fees) or disbursements of any kind or nature whatsoever that may be imposed on, incurred by or asserted against Agent or any Lender in connection with any investigative, administrative or judicial proceeding (whether or not such Lender or Agent shall be designated a party thereto) or any other claim by any Person relating to or arising out of any Loan Document or any actual or proposed use of proceeds of the Loans or any o f the Obligations, or any activities of any Company or its Affiliates; provided that no Lender nor Agent shall have the right to be indemnified under this Section 10.6 for its own gross negligence or willful misconduct as determined by a court of competent jurisdiction. All obligations provided for in this Section 10.6 shall survive any termination of this Agreement.

Section 10.7. Obligations Several; No Fiduciary Obligations. The obligations of the Lenders hereunder are several and not joint. Nothing contained in this Agreement and no action taken by Agent or the Lenders pursuant hereto shall be deemed to constitute Agent or the Lenders a partnership, association, joint venture or other entity. No default by any Lender hereunder shall excuse the other Lenders from any obligation under this Agreement; but no Lender shall have or acquire any additional obligation of any kind by reason of such default. The relationship between Borrowers and the Lenders with respect to the Loan Documents and the Related Writings is and shall be solely that of debtors and creditors, respectively, and neither Agent nor any Lender shall have any fiduciary obligation toward any Credit Party with respect to any such documents or the transactions contemplated thereby.

Section 10.8. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts and by facsimile signature, each of which counterparts when so executed and delivered shall be deemed to be an original and all of which taken together shall constitute but one and the same agreement.

Anything herein to the contrary notwithstanding, any Lender may at any time make a collateral assignment of all or any portion of its rights under the Loan Documents to a Federal Reserve Bank, and no such assignment shall release such assigning Lender from its obligations hereunder.

(c) Minimum Amount. Each such assignment shall be in a minimum amount of the lesser of Ten Million Dollars ($10,000,000) of the assignor’s Commitment and interest herein, or the entire amount of the assignor’s Commitment and interest herein.

(d) Assignment Fee. Unless the assignment shall be to an affiliate of the assignor or the assignment shall be due to merger of the assignor or for regulatory purposes, either the assignor or the assignee shall remit to Agent, for its own account, an administrative fee of Three Thousand Five Hundred Dollars ($3,500).

(e) Assignment Agreement. Unless the assignment shall be due to merger of the assignor or a collateral assignment for regulatory purposes, the assignor shall (i) cause the assignee to execute and deliver to Administrative Borrower and Agent an Assignment Agreement, and (ii) execute and deliver, or cause the assignee to execute and deliver, as the case may be, to Agent such additional amendments, assurances and other writings as Agent may reasonably require.

(f) Non-U.S. Assignee. If the assignment is to be made to an assignee that is organized under the laws of any jurisdiction other than the United States or any state thereof, the assignor Lender shall cause such assignee, at least five Business Days prior to the effective date of such assignment, (i) to represent to the assignor Lender (for the benefit of the assignor Lender, Agent and Borrowers) that under applicable law and treaties no taxes will be required to be withheld by Agent, Borrowers or the assignor with respect to any payments to be made to such assignee in respect of the Loans hereunder, (ii) to furnish to the assignor Lender (and, in the case of any assignee registered in the Register (as defined below), Agent and Borrowers) either U.S. Internal Revenue Service Form W-8ECI or U.S. Internal Revenue Service Form W-8BEN, as applicable (wherein such assignee 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 assignor, Agent and Borrowers) to provide to the assignor Lender (and, in the case of any assignee registered in the Register, to Agent and Borrowers) a new Form W-8ECI or Form W-8BEN, as applicable, upon the expiration or obsolescence of any previously delivered form

and comparable statements in accordance with applicable U.S. laws and regulations and amendments duly executed and completed by such assignee, and to comply from time to time with all applicable U.S. laws and regulations with regard to such withholding tax exemption.

(g) Deliveries by Borrowers.

After delivery of the new Note or Notes, the assignor’s Note or Notes being replaced shall be returned to Borrowers marked “replaced”.

(h) Effect of Assignment. Upon satisfaction of all applicable requirements set forth in subsections (a) through (g) above, and any other condition contained in this Section 10.10, (i) the assignee shall become and thereafter be deemed to be a “Lender” for the purposes of this Agreement, (ii) the assignor shall be released from its obligations hereunder to the extent that its interest has been assigned, (iii) in the event that the assignor’s entire interest has been assigned, the assignor shall cease to be and thereafter shall no longer be deemed to be a “Lender” and (iv) the signature pages hereto and Schedule 1 hereto shall be automatically amended, without further action, to reflect the result of any such assignment.

(i) Agent to Maintain Register. Agent shall maintain at the address for notices referred to in Section 10.4 hereof a copy of each Assignment Agreement delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and Borrowers, Agent and the Lenders may treat each Person whose name is recorded in the Register as the owner of the Loan recorded therein for all purposes of this Agreement. The Register shall be available for inspection by Borrowers or any Lender at any reasonable time and from time to time upon reasonable prior notice.

Section 10.11. Sale of Participations. Any Lender may, in the ordinary course of its commercial banking business and in accordance with applicable law, at any time sell participations to one or more Eligible Transferees (each a “Participant”) in all or a portion of its rights or obligations under this Agreement and the other Loan Documents (including, without limitation, all or a portion of the Commitment and the Loans and participations owing to it and the Note held by it); provided that:

(a) any such Lender’s obligations under this Agreement and the other Loan Documents shall remain unchanged;

(b) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations;

(c) the parties hereto shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and each of the other Loan Documents;

(d) such Participant shall be bound by the provisions of Section 8.5 hereof, and the Lender selling such participation shall obtain from such Participant a written confirmation of its agreement to be so bound; and

(e) no Participant (unless such Participant is itself a Lender) shall be entitled to require such Lender to take or refrain from taking action under this Agreement or under any other Loan Document, except that such Lender may agree with such Participant that such Lender will not, without such Participant’s consent, take action of the type described as follows:

(i) increase the portion of the participation amount of any Participant over the amount thereof then in effect, or extend the Commitment Period, without the written consent of each Participant affected thereby; or

(ii) reduce the principal amount of or extend the time for any payment of principal of any Loan, or reduce the rate of interest or extend the time for payment of interest on any Loan, or reduce the facility fee, without the written consent of each Participant affected thereby.

Borrowers agree that any Lender that sells participations pursuant to this Section shall still be entitled to the benefits of Article III hereof, notwithstanding any such transfer; provided, however, that the obligations of Borrowers shall not increase as a result of such transfer and Borrowers shall have no obligation to any Participant.

Section 10.12. Patriot Act Notice. Each Lender and Agent (for itself and not on behalf of any other party) hereby notifies the Credit Parties that, pursuant to the requirements of the Patriot Act, such Lender and Agent are required to obtain, verify and record information that identifies the Credit Parties, which information includes the name and address of the Credit Parties and other information that will allow such Lender or Agent, as applicable, to identify the Credit Parties in accordance with the Patriot Act. Administrative Borrower shall provide, to the extent commercially reasonable, such information and take such actions as are reasonably requested by Agent or any Lenders in order to assist Agent and the Lender in maintaining compliance with the Patriot Act.

Section 10.13. Severability of Provisions; Captions; Attachments. Any provision of this Agreement that shall be 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 or affecting the validity or enforceability of such provision in any other jurisdiction. The several captions to Sections and subsections herein are inserted for convenience only and shall be ignored in interpreting the provisions of this Agreement. Each schedule or exhibit attached to this Agreement shall be incorporated herein and shall be deemed to be a part hereof.

Section 10.14. Entire Agreement. This Agreement, any Note and any other Loan Document or other agreement, document or instrument attached hereto or executed on or as of the Closing Date integrate all of the terms and conditions mentioned herein or incidental hereto and supersede all oral representations and negotiations and prior writings with respect to the subject matter hereof.

Section 10.15. Legal Representation of Parties. The Loan Documents were negotiated by the parties with the benefit of legal representation and any rule of construction or interpretation otherwise requiring this Agreement or any other Loan Document to be construed or interpreted against any party shall not apply to any construction or interpretation hereof or thereof.

Section 10.16. Currency.

(a) Currency Equivalent Generally. For the purposes of making valuations or computations under this Agreement (but not for the purposes of the preparation of any financial statements delivered pursuant hereto), unless expressly provided otherwise, where a reference is made to a dollar amount the amount is to be considered as the amount in Dollars and, therefor, each other currency shall be converted into the Dollar Equivalent.

(b) Judgment Currency. If Agent, on behalf of the Lenders, obtains a judgment or judgments against any Credit Party in an Alternate Currency, the obligations of such Credit Party in respect of any sum adjudged to be due to Agent or the Lenders hereunder or under the Notes (the “Judgment Amount”) shall be discharged only to the extent that, on the Business Day following receipt by Agent of the Judgment Amount in the Alternate Currency, Agent, in accordance with normal banking procedures, purchases Dollars with the Judgment Amount in such Alternate Currency.
