amount less than the sum of (A) the Maximum Drawing Amount of all Letters of Credit, and (B) all Loans then outstanding.

     (b) No reduction or termination of the Total Commitment once made may be revoked; the portion of the Total Commitment reduced or terminated may not be reinstated; and amounts in respect of such reduced or terminated portion may not be reborrowed.

Any such increase in the Total Commitment shall require, among other things, the satisfaction of such conditions precedent as the Administrative Agent may reasonably require, including, without limitation, the Administrative Agent’s receipt of evidence of applicable corporate authorization and other corporate documentation from the Borrower and the Guarantor and the legal opinion of counsel to the Borrower and the Guarantor, each in form and substance satisfactory to the Administrative Agent and such Banks as are participating in such increase.

     (a) The Borrower hereby unconditionally promises to pay (i) to the Administrative Agent for the pro rata account of the Banks, the then unpaid principal amount of the Syndicated Loans on the Maturity Date, (ii) to the Administrative Agent for the account of the applicable Bank, the then unpaid principal amount of such Bank’s Competitive Bid Loan on the last day of the Interest Period applicable to such Loan, and (iii) to the Swing Line Bank, for its account, the then unpaid principal amount of each Swing Line Loan on the earlier of the Maturity Date and the first date after such Swing Line Loan is made that is the 15^th or last day of a calendar month and is at least two Business Days after such Swing Line Loan is made; provided that on each date that a Syndicated Loan or Competitive Bid Loan is made, the Borrower shall repay all Swing Line Loans then outstanding.

     (b) Each Bank shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Bank resulting from

each Loan made by such Bank, including the amounts of principal and interest payable and paid to such Bank from time to time hereunder.

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

     (d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this §2.4 shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Bank or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

     (e) Any Bank may request that any Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Bank a promissory note payable to the order of such Bank (or, if requested by Bank, to such Bank and its registered assigns) and in a form approved by the Administrative Agent. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to §20) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

          §2.5. Interest on Loans.

     (a) The outstanding principal amount of the Syndicated Loans shall bear interest at the rate per annum equal to (i) the Applicable Base Rate on Base Rate Loans, (ii) the Applicable Eurodollar Rate on Eurodollar Loans and (iii) the Applicable Swing Line Rate on Swing Line Loans.

     (b) Interest shall be payable (i) quarterly in arrears on the first Business Day of each quarter, with the first such payment commencing October 1, 2006, on Base Rate Loans, (ii) on the last day of the applicable Interest Period, and if such Interest Period is longer than three months, also on the last day of each three month period following the commencement of such Interest Period, on Eurodollar Loans, and (iii) on the Maturity Date for all Loans.

          §2.6. Requests for Syndicated Loans.

     (a) The Borrower shall give to the Administrative Agent written notice in the form of Exhibit A hereto (or telephonic notice confirmed in writing or a facsimile in the form of Exhibit A hereto) of each Syndicated Loan requested hereunder (a “Syndicated Loan Request”) not later than (a) 11:00 a.m. (New York time) on the proposed Drawdown Date of any Base Rate Loan, or (b) 11:00 a.m. (New York time) three (3) Eurodollar Business Days prior to the proposed Drawdown Date of any Eurodollar Loan.

Each such Syndicated Loan Request shall specify (A) the principal amount of the Syndicated Loan requested, (B) the proposed Drawdown Date of such Syndicated Loan, (C) whether such Syndicated Loan requested is to be a Base Rate Loan or a Eurodollar Loan, and (D) the Interest Period for such Syndicated Loan, if a Eurodollar Loan. Each Syndicated Loan requested shall be in a minimum amount of $10,000,000. Each such Syndicated Loan Request shall reflect the Maximum Drawing Amount of all Letters of Credit outstanding and the amount of all Loans outstanding (including Competitive Bid Loans and Swing Line Loans). Syndicated Loan Requests made hereunder shall be irrevocable and binding on the Borrower, and shall obligate the Borrower to accept the Syndicated Loan requested from the Banks on the proposed Drawdown Date.

     (b) Each of the representations and warranties made by the Borrower to the Banks or the Administrative Agent in this Agreement or any other Loan Document shall be true and correct in all material respects when made and shall, for all purposes of this Agreement, be deemed to be repeated by the Borrower on and as of the date of the submission of a Syndicated Loan Request, Competitive Bid Quote Request, or Letter of Credit Application and on and as of the Drawdown Date of any Loan or the date of issuance of any Letter of Credit (except to the extent (i) of changes resulting from transactions contemplated or permitted by this Agreement and the other Loan Documents, (ii) of changes occurring in the ordinary course of business that either individually or in the aggregate do not result in a Material Adverse Effect, or (iii) that such representations and warranties expressly relate only to an earlier date).

     (c) The Administrative Agent shall promptly notify each Bank of each Syndicated Loan Request received by the Administrative Agent (i) on the proposed Drawdown Date of any Base Rate Loan, or (ii) three (3) Eurodollar Business Days prior to the proposed Drawdown Date of any Eurodollar Loan.

          §2.7. Election of Eurodollar Rate; Notice of Election; Interest Periods; Minimum Amounts.

     (a) At the Borrower’s option, so long as no Default or Event of Default has occurred and is then continuing, the Borrower may (i) elect to convert any Base Rate Loan or a portion thereof to a Eurodollar Loan, (ii) at the time of any Syndicated Loan Request, specify that such requested Loan shall be a Eurodollar Loan, or (iii) upon expiration of the applicable Interest Period, elect to maintain an existing Eurodollar Loan as such, provided that the Borrower give notice to the Administrative Agent pursuant to §2.7(b) hereof. Upon determining any Eurodollar Rate, the Administrative Agent shall forthwith provide notice thereof to the Borrower and the Banks, and each such notice to the Borrower shall be considered prima facie correct and binding, absent manifest error.

     (b) Three (3) Eurodollar Business Days prior to the making of any Eurodollar Loan or the conversion of any Base Rate Loan to a Eurodollar Loan, or, in the case of an outstanding Eurodollar Loan, the expiration date of the applicable Interest Period, the Borrower shall give written, telex or facsimile notice (or telephonic notice promptly confirmed in a writing or a facsimile) received by the Administrative Agent not later than 11:00 a.m. (New York time) of its election pursuant to §2.7(a). Each such notice

delivered to the Administrative Agent shall specify the aggregate principal amount of the Syndicated Loans to be borrowed or maintained as or converted to Eurodollar Loans and the requested duration of the Interest Period that will be applicable to such Eurodollar Loan, and shall be irrevocable and binding upon the Borrower. If the Borrower shall fail to give the Administrative Agent notice of its election hereunder together with all of the other information required by this §2.7(b) with respect to any Syndicated Loan, whether at the end of an Interest Period or otherwise, such Syndicated Loan shall be deemed a Base Rate Loan. The Administrative Agent shall promptly notify the Banks in writing (or by telephone confirmed in writing or by facsimile) of such election.

     (c) Notwithstanding anything herein to the contrary, the Borrower may not specify an Interest Period that would extend beyond the Maturity Date.

     (d) No conversion of Loans pursuant to this §2.7 may result in any Eurodollar Borrowing that is less than $5,000,000. In no event shall the Borrower have more than ten (10) different Interest Periods for Borrowings of Eurodollar Loans outstanding at any time.

     (e) Subject to the terms and conditions of §5.8 hereof, if any Affected Bank demands compensation under §5.5(c) or (d) with respect to any Eurodollar Loan, the Borrower may at any time, upon at least three (3) Business Days’ prior written notice to the applicable Administrative Agent, elect to convert such Eurodollar Loan into a Base Rate Loan (on which interest and principal shall be payable contemporaneously with the related Eurodollar Loans of the other Banks). Thereafter, and until such time as the Affected Bank notifies the Administrative Agent that the circumstances giving rise to the demand for compensation under §5.5(c) or (d) no longer exist, all requests for Eurodollar Loans from such Affected Bank shall be deemed to be requests for Base Rate Loans. Once the Affected Bank notifies the Administrative Agent that such circumstances no longer exist, the Borrower may elect that the principal amount of each such Loan converted hereunder shall again bear interest as Eurodollar Loans beginning on the first day of the next succeeding Interest Period applicable to the related Eurodollar Loans of the other Banks.

          §2.8. Funds for Syndicated Loans. Not later than 1:00 p.m. (New York time) on the proposed Drawdown Date of Syndicated Loans, each of the Banks will make available to the Administrative Agent at the Administrative Agent’s Account, in immediately available funds, the amount of its Commitment Percentage of the amount of the requested Loan. Upon receipt from each Bank of such amount, and upon receipt of the documents required by §10 and §11 and the satisfaction of the other conditions set forth therein, the Administrative Agent will make available to the Borrower the aggregate amount of such Syndicated Loans made available by the Banks. The failure or refusal of any Bank to make available to the Administrative Agent at the aforesaid time and place on any Drawdown Date the amount of its Commitment Percentage of the requested Syndicated Loan shall not relieve any other Bank from its several obligations hereunder to make available to the Administrative Agent the amount of such Bank’s Commitment Percentage of the requested Loan.

          §2.9. Maturity of the Loans and Reimbursement Obligations. The Borrower promises to pay on the Maturity Date, and there shall become absolutely due and payable on the Maturity Date, all of the Loans and unpaid Reimbursement Obligations outstanding on such date, together with any and all accrued and unpaid interest thereon and any fees and other amounts owing hereunder.

          §2.10. Optional Prepayments or Repayments of Loans. Subject to the terms and conditions of §5.8, the Borrower shall have the right, at its election, to repay or prepay the outstanding amount of the Loans, as a whole or in part, at any time without penalty or premium. The Borrower shall give the Administrative Agent no later than 11:00 a.m. (New York time) (a) on the proposed date of prepayment or repayment of Base Rate Loans, and (b) three (3) Eurodollar Business Day prior to the proposed date of prepayment or repayment of all other Loans, written notice (or telephonic notice confirmed in writing or by facsimile) of any proposed prepayment or repayment pursuant to this §2.10, specifying the proposed date of prepayment or repayment of Loans and the principal amount to be paid. Notwithstanding the foregoing, the Borrower may not prepay any Competitive Bid Loans without the consent of the applicable Bank. The Administrative Agent shall promptly notify each Bank by written notice (or telephonic notice confirmed in writing or by facsimile) of such notice of payment.

          §2.11. Swing Line Loans; Settlements.

     (a) Notwithstanding the notice and minimum amount requirements set forth in §2.6 but otherwise in accordance with the terms and conditions of this Agreement, and solely for ease of administration of the Syndicated Loans, the Swing Line Bank may, but shall not be required to, fund Base Rate Loans made in accordance with the provisions of this Agreement (“Swing Line Loans”).

     At the discretion of the Swing Line Bank, Swing Line Loans may be in amounts less than $10,000,000 provided that the outstanding amount of Swing Line Loans advanced by the Swing Line Bank hereunder shall not exceed $100,000,000 at any time. Each Bank shall remain severally and unconditionally liable to fund its pro rata share (based upon each Bank’s Commitment Percentage) of such Swing Line Loans on each Swing Line Settlement Date and, in the event the Swing Line Bank chooses not to fund any Swing Line Loans requested on any date, to fund its Commitment Percentage of the Base Rate Loans requested, subject to satisfaction of the provisions hereof relating to such Bank’s Commitment to make the Base Rate Loans. Prior to each Swing Line Settlement, all payments or repayments of the principal of, and interest on, Swing Line Loans shall be credited to the account of the Swing Line Bank.

     (b) The Banks shall effect Swing Line Settlements on (i) the Business Day immediately following any day which the Administrative Agent gives written notice to effect a Swing Line Settlement, (ii) the Business Day immediately following the Administrative Agent’s becoming aware of the existence of any Default or Event of Default and (iii) the Maturity Date (each such date, a “Swing Line Settlement Date”). One (1) Business Day prior to each such Swing Line Settlement Date, the Administrative Agent shall give telephonic notice (followed promptly by written confirmation) to the

Banks of (A) the respective outstanding amount of Syndicated Loans made by each Bank as at the close of business on the prior day, (B) the amount that any Bank, as applicable (a “Swing Line Settling Bank”), shall pay to effect a Swing Line Settlement (a “Swing Line Settlement Amount”) and (C) the portion (if any) of the aggregate Swing Line Settlement Amount to be paid to each Bank. A statement of the Administrative Agent submitted to the Banks with respect to any amounts owing hereunder shall be prima facie evidence of the amount due and owing. Each Swing Line Settling Bank shall, not later than 1:00 p.m. (New York time) on each Swing Line Settlement Date, effect a wire transfer of immediately available funds to the Administrative Agent at its Loan Office in the amount of such Bank’s Swing Line Settlement Amount. The Administrative Agent shall, as promptly as practicable during normal business hours on each Swing Line Settlement Date, effect a wire transfer of immediately available funds to each Bank of the Swing Line Settlement Amount to be paid to such Bank. All funds advanced by any Bank as a Swing Line Settling Bank pursuant to this §2.11 (b) shall for all purposes be treated as a Base Rate Loan made by such Swing Line Settling Bank to the Borrower, and all funds received by any Bank pursuant to this §2.11 (b) shall for all purposes be treated as repayment of amounts owed by the Borrower with respect to Base Rate Loans made by such Bank.

     (c) The Administrative Agent may (unless notified to the contrary by any Swing Line Settling Bank by 10:00 a.m. (New York time) on the Settlement Date) assume that each Swing Line Settling Bank has made available (or will make available by the time specified in §2.11(b)) to the Administrative Agent its Swing Line Settlement Amount, and the Administrative Agent may (but shall not be required to), in reliance upon such assumption, make available to each applicable Bank its share (if any) of the aggregate Swing Line Settlement Amount. If the Swing Line Settlement Amount of such Swing Line Settling Bank is made available to the Administrative Agent by such Swing Line Settling Bank on a date after such Swing Line Settlement Date, such Swing Line Settling Bank shall pay the Swing Line Bank on demand an amount equal to the product of (i) the average, computed for the period referred to in clause (iii) below, of the weighted average annual interest rate paid by the Swing Line Bank for federal funds acquired by the Swing Line Bank during each day included in such period times (ii) such Swing Line Settlement Amount times (iii) a fraction, the numerator of which is the number of days that elapse from and including such Swing Line Settlement Date to but not including the date on which such Swing Line Settlement Amount shall become immediately available to the Swing Line Bank, and the denominator of which is 365. Upon payment of such amount such Swing Line Settling Bank shall be deemed to have delivered its Swing Line Settlement Amount on the Swing Line Settlement Date and shall become entitled to interest payable by the Borrower with respect to such Swing Line Settling Bank’s Swing Line Settlement Amount as if such share were delivered on the Swing Line Settlement Date. If such Swing Line Settlement Amount is not in fact made available to the Swing Line Bank by such Swing Line Settling Bank within three (3) Business Days of such Swing Line Settlement Date, the Swing Line Bank shall be entitled to recover such amount from the Borrower, with interest thereon at the Applicable Base Rate.

     (d) After any Swing Line Settlement Date, any payment by the Borrower of Swing Line Loans hereunder shall be allocated among the Banks, in amounts determined so as to provide that after such application and the related Swing Line Settlement, the outstanding amount of Syndicated Loans of each Bank equals, as nearly as practicable, such Bank’s Commitment Percentage of the aggregate amount of Syndicated Loans.

§3. LETTERS OF CREDIT.

          §3.1. Letter of Credit Commitments.

     (a) Subject to the terms and conditions hereof and the receipt by the Administrative Agent of a written notice in the form of Exhibit B hereto (a “Letter of Credit Request”) reflecting the Maximum Drawing Amount of all Letters of Credit (including the requested Letter of Credit), and receipt by an Issuing Bank, with a copy to the Administrative Agent, of a Letter of Credit Application, such Issuing Bank, on behalf of the Banks and in reliance upon the representations and warranties of the Borrower contained herein and the agreement of the Banks contained in §3.1(c) hereof, agrees to issue standby Letters of Credit (including so-called “direct pay” standby Letters of Credit) for the account of the Borrower (which may, with such Issuing Bank’s consent, incorporate automatic renewals for periods of up to twelve (12) months), in such form as may be requested from time to time by the Borrower and agreed to by such Issuing Bank; provided, however, that, after giving effect to such request, the aggregate Maximum Drawing Amount of all Letters of Credit issued at any time shall not exceed the Total Commitment minus the aggregate outstanding amount of the Loans; provided further, that no Letter of Credit shall have an expiration date later than the earlier of (i) eighteen (18) months after the date of issuance (which may incorporate automatic renewals for periods of up to twelve (12) months), or (ii) five (5) Business Days prior to the Maturity Date; and provided further, that the aggregate face amount of all Letters of Credit issued by any one Issuing Bank shall not at any time exceed the amount set forth opposite the name of such Issuing Bank on Schedule 3.1 hereto, as such amount may be increased (in the sole discretion of such Issuing Bank) or decreased (if so agreed by such Issuing Bank and the Borrower) by the execution and delivery by such Issuing Bank, the Borrower, the Guarantor and the Administrative Agent of an instrument in substantially the form of Schedule 3.1.1 hereto. Each Issuing Bank will promptly confirm to the Administrative Agent the issuance of each Letter of Credit specifying the face amount thereof, and the Administrative Agent will transmit such information to the Banks.

     (b) Each Letter of Credit shall be denominated in Dollars or, in accordance with and subject to the terms of §3.1(e) hereof, in Canadian Dollars.

     (c) Each Bank severally agrees that it shall be absolutely liable, without regard to the occurrence of any Default or Event of Default, the termination of the Total Commitment pursuant to §12.2, or any other condition precedent or circumstance whatsoever (other than as stated in the next sentence hereof), to the extent of such Bank’s Commitment Percentage to reimburse each Issuing Bank on demand for the amount of each draft paid by such Issuing Bank under each Letter of Credit issued by such Issuing

Bank to the extent that such amount is not reimbursed by the Borrower pursuant to §3.2 (such agreement of a Bank being called herein the “Letter of Credit Participation” of such Bank). Each Bank agrees that its obligation to reimburse each Issuing Bank pursuant to this §3.1(c) shall not be affected in any way by any circumstance whatsoever other than the gross negligence or willful misconduct of such Issuing Bank, provided that the making of a payment under a Letter of Credit against documents that appear on their face to substantially comply with the terms and conditions of such Letter of Credit shall not be deemed to be gross negligence or willful misconduct.

     (d) Each such reimbursement payment made by a Bank to an Issuing Bank shall be made to an account of such Issuing Bank in the United States of America and shall be treated as the purchase by such Bank of a participating interest in the applicable Reimbursement Obligation under §3.2 in an amount equal to such payment. Each Bank shall share in accordance with its participating interest in any interest which accrues pursuant to §3.2.

     (e) (i) The Borrower shall be entitled to request that one or more Letters of Credit be denominated in Canadian Dollars for the account of any Canadian Subsidiary of the Borrower (each a “Canadian Dollar Letter of Credit”); provided that (i) the aggregate undrawn face amount of all Canadian Dollar Letters of Credit may not exceed C$200,000,000 at any time and (ii) each Canadian Dollar Letter of Credit shall provide for payment of any drawing thereunder on a date not earlier than three Business Days after the relevant Issuing Bank determines that the documents submitted in connection with such drawing appear on their face to substantially comply with the terms and conditions of such Letter of Credit.

     (ii) The Letter of Credit Application in respect of each Canadian Dollar Letter of Credit shall be signed by the Borrower; provided that nothing therein shall be deemed to alter the obligations of the Borrower under this Agreement in respect of any drawing under any such Letter of Credit.

     (iii) If an Issuing Bank makes a payment in Canadian Dollars pursuant to a Canadian Dollar Letter of Credit, the amount of such payment shall, for all purposes of this Agreement (but without prejudice to the terms of such Letter of Credit), immediately be deemed converted into the U.S. Dollar Equivalent thereof and shall for all purposes hereof be deemed to have been made in U.S. Dollars in said amount.

     (f) As of the Effective Date, the Existing Letters of Credit shall automatically be deemed to be Letters of Credit for all purposes of this Agreement, having the respective face amounts specified in Schedule 3.1.2 hereof.

     (g) The parties acknowledge and agree that (a) certain of the Existing Letters of Credit have been issued by Affiliates of Issuing Banks identified in Schedule 3.1.2 hereof, and that (b) an Issuing Bank may hereafter comply with the provisions of §3.1 in respect of the issuance of Canadian Dollar Letters of Credit by arranging for an Affiliate of such Issuing Bank organized under the laws of Canada to issue such Canadian Dollar Letter of Credit (each Letter of Credit issued by an Affiliate of an Issuing Bank as

provided herein being herein referred to as a “Bank Affiliate Letter of Credit”), provided that such Issuing Bank shall, prior to such issuance, have notified the Administrative Agent and the Borrower of the identity of such Affiliate. The parties agree that (1) each Bank Affiliate Letter of Credit is and shall be a “Letter of Credit” for all purposes of this Agreement; (2) each reference in the definition of “Reimbursement Obligation” and in §3.2, §3.3 and §3.4 to an Issuing Bank shall be deemed to include the issuer of each such Bank Affiliate Letter of Credit; (3) notwithstanding the foregoing, the issuance, extension or renewal of each Letter of Credit shall remain subject to the conditions and requirements of §3.1 and §11, and each provision of this Agreement, including without limitation the last sentence of §3.1(a) and §3.5, requiring the giving of a notice hereunder by or to an Issuing Bank shall be deemed to refer to such Issuing Bank and not to such Affiliate; and (4) the obligations of the Banks, the Borrower and the Guarantor to each Issuing Bank shall, in the case of each Bank Affiliate Letter of Credit, inure to the benefit of the Affiliate issuing or having issued such Bank Affiliate Letter of Credit and be enforceable by such Affiliate and/or by such Issuing Bank on behalf of such Affiliate. Each Canadian Dollar Letter of Credit issued by a Canadian Affiliate of an Issuing Bank shall be issued on a Business Day which is not a day on which banking institutions in Toronto and Montreal, Canada are authorized by law to close.

          §3.2. Reimbursement Obligation of the Borrower. In order to induce the Issuing Banks to issue, extend and renew each Letter of Credit, the Borrower hereby agrees to reimburse or pay to each Issuing Bank, with respect to each Letter of Credit issued, extended or renewed by such Issuing Bank hereunder, as follows:

     (a) if any draft presented under any Letter of Credit is honored by such Issuing Bank or such Issuing Bank otherwise makes payment with respect thereto, the sum of (i) the amount paid by such Issuing Bank under or with respect to such Letter of Credit (except that in the case of a payment in Canadian Dollars, it shall reimburse or pay the U.S. Dollar Equivalent thereof), and (ii) the amount of any taxes, fees, charges or other costs and expenses whatsoever incurred by such Issuing Bank in connection with any payment made by such Issuing Bank under, or with respect to, such Letter of Credit; provided, however, if the Borrower does not reimburse such Issuing Bank on the Drawdown Date, such amount shall, provided that no Event of Default under §§12.1(g) or 12.1(h) has occurred, become automatically a Syndicated Loan which is a Base Rate Loan advanced hereunder in an amount equal to such sum; and

     (b) upon the Maturity Date or the acceleration of the Reimbursement Obligations with respect to all Letters of Credit in accordance with §12, an amount equal to the then Maximum Drawing Amount of all outstanding Letters of Credit shall be paid by the Borrower to the Administrative Agent to be held as cash collateral for the applicable Reimbursement Obligations, and the Borrower hereby grants to the Administrative Agent a security interest therein.

          §3.3. Obligations Absolute. The Borrower’s obligations under this §3 shall be absolute and unconditional under any and all circumstances and irrespective of the occurrence of any Default or Event of Default or any condition precedent whatsoever or any setoff, counterclaim or defense to payment which the Borrower may have or have had against any

Issuing Bank, any Bank or any beneficiary of a Letter of Credit, and the Borrower expressly waives any such rights that it may have with respect thereto. The Borrower further agrees with each Issuing Bank and the Banks that such Issuing Bank and the Banks (i) shall not be responsible for, and the Borrower’s Reimbursement Obligations under §3.2 shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged (unless due to the willful misconduct of such Issuing Bank or any other Bank), or any dispute between or among the Borrower and the beneficiary of any Letter of Credit or any financing institution or other party to which any Letter of Credit may be transferred or any claims or defenses whatsoever of the Borrower against the beneficiary of any Letter of Credit or any such transferee, and (ii) shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit except to the extent of their own willful misconduct. The Borrower agrees that any action taken or omitted by any Issuing Bank or any Bank in good faith under or in connection with any Letter of Credit and the related drafts and documents shall be binding upon the Borrower and shall not result in any liability on the part of such Issuing Bank or any Bank (or their respective affiliates) to the Borrower. Nothing herein shall constitute a waiver by the Borrower of any of its rights against any beneficiary of a Letter of Credit.

          §3.4. Reliance by the Issuing Banks. To the extent not inconsistent with §3.3, each Issuing Bank shall be entitled to rely, and shall be fully protected in relying, upon any Letter of Credit, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, facsimile, telex or teletype message, statement, order or other document believed by such Issuing Bank in good faith to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel, independent accountants and other experts selected by such Issuing Bank.

          §3.5. Notice Regarding Letters of Credit. One (1) Business Day prior to the issuance of any Letter of Credit or any amendment, extension or termination thereof, the applicable Issuing Bank shall notify the Administrative Agent of the terms of such Letter of Credit, amendment, extension or termination. In the case of any such issuance, amendment or extension, the Administrative Agent will promptly notify such Issuing Bank whether such issuance, amendment or extension is permissible under the limitation set forth in the proviso to §2.1(a). On the day of any drawing under any Letter of Credit, such Issuing Bank shall notify the Administrative Agent of such drawing, specifying the amount thereof, and on the day of any payment under any Letter of Credit, such Issuing Bank shall notify the Administrative Agent of such payment, specifying the amount thereof and, in the case of a payment under a Canadian Dollar Letter of Credit, the U.S. Dollar Equivalent thereof.

          §3.6. Letter of Credit Fee; Issuance Fee. The Borrower shall pay a fee (the “Letter of Credit Fee”) equal to the Applicable L/C Rate on the Maximum Drawing Amount to the Administrative Agent for the account of the Banks, to be shared pro rata by the Banks in accordance with their respective Commitment Percentages. The Letter of Credit Fee shall be payable quarterly in arrears on the third Business Day of each calendar quarter for the quarter just ended, with the first such payment being due on October 4, 2006, and on the Maturity Date. In addition, an issuing fee (the “Issuance Fee”) with respect to each Letter of Credit to be agreed

upon annually between the Borrower and each Issuing Bank shall be payable by the Borrower to such Issuing Bank for its account.

§4. COMPETITIVE BID LOANS.

          §4.1. The Competitive Bid Option. In addition to the Syndicated Loans made pursuant to §2 hereof, the Borrower may request Competitive Bid Loans pursuant to the terms of this §4. The Banks may, but shall have no obligation to, make offers for Competitive Bid Loans and the Borrower may, but shall have no obligation to, accept such offers in the manner set forth in this §4. Notwithstanding any other provision herein to the contrary, at no time shall the aggregate principal amount of Competitive Bid Loans outstanding at any time exceed the Total Commitment minus the sum of (a) the aggregate outstanding principal amount of Syndicated Loans (including the Swing Loans) plus (b) the Maximum Drawing Amount of Letters of Credit, outstanding at such time.

          §4.2. Competitive Bid Loan Accounts; Competitive Bid Loans.

     (a) The obligation of the Borrower to repay the outstanding principal amount of any and all Competitive Bid Loans, plus interest at the applicable rate accrued thereon, shall be evidenced by this Agreement and by individual loan accounts (the “Competitive Bid Loan Accounts” and individually, a “Competitive Bid Loan Account”) maintained by the Administrative Agent on its books for each of the Banks, it being the intention of the parties hereto that, except as provided for in paragraph (b) of this §4.2, the Borrower’s obligations with respect to Competitive Bid Loans are to be evidenced only as stated herein and not by separate promissory notes.

     (b) Any Bank may at any time, and from time to time, request that any Competitive Bid Loans outstanding to such Bank be evidenced by a promissory note of the Borrower in the form approved by the Administrative Agent, dated as of the Effective Date and completed with appropriate insertions.

     (c) The Borrower irrevocably authorizes the Administrative Agent to make or cause to be made, in connection with a Drawdown Date of any Competitive Bid Loan or at the time of receipt of any payment of principal on the applicable Bank’s Competitive Bid Loan Account, an appropriate notation on the Administrative Agent’s records, reflecting the making of the Competitive Bid Loan, or the receipt of such payment (as the case may be). The outstanding amount of the Competitive Bid Loans set forth on the Administrative Agent’s records, shall be prima facie evidence of the principal amount thereof owing and unpaid to such Bank, but the failure to record, or any error in so recording, any such amount shall not limit or otherwise affect the obligations of the Borrower hereunder to make payments of principal of or interest on any Competitive Bid Loan when due.

          §4.3. Competitive Bid Quote Request; Invitation for Competitive Bid Quotes.

     (a) When the Borrower wishes to request offers to make Competitive Bid Loans under this §4, it shall transmit to the Administrative Agent by telex or facsimile a

Competitive Bid Quote Request substantially in the form of Exhibit E hereto (a “Competitive Bid Quote Request”) so as to be received no later than 1:00 p.m. (New York time) (x) five (5) Eurodollar Business Days prior to the requested Drawdown Date in the case of a Eurodollar Competitive Bid Loan or (y) one (1) Business Day prior to the requested Drawdown Date in the case of an Absolute Competitive Bid Loan, specifying:

     (i) the requested Drawdown Date (which must be a Eurodollar Business Day in the case of a Eurodollar Competitive Bid Loan or a Business Day in the case of an Absolute Competitive Bid Loan);

     (ii) the aggregate amount of such Competitive Bid Loans, which shall be $10,000,000 or larger multiple of $1,000,000;

     (iii) the duration of the Interest Period(s) applicable thereto, subject to the provisions of the definition of Interest Period; and

     (iv) whether the Competitive Bid Quotes requested are for Eurodollar Competitive Bid Loans or Absolute Competitive Bid Loans.

The Borrower may request offers to make Competitive Bid Loans for more than one Interest Period in a single Competitive Bid Quote Request. No new Competitive Bid Quote Request shall be given until the Borrower has notified the Administrative Agent of its acceptance or non-acceptance of the Competitive Bid Quotes relating to any outstanding Competitive Bid Quote Request.

     (b) Promptly upon receipt of a Competitive Bid Quote Request, the Administrative Agent shall send to the Banks by telecopy or facsimile transmission an Invitation for Competitive Bid Quotes substantially in the form of Exhibit F hereto, which shall constitute an invitation by the Borrower to each Bank to submit Competitive Bid Quotes in accordance with this §4.

          §4.4. Alternative Manner of Procedure. If, after receipt by the Administrative Agent and each of the Banks of a Competitive Bid Quote Request from the Borrower in accordance with §4.3, the Administrative Agent or any Bank shall be unable to complete any procedure of the auction process described in §§4.5 through 4.6 (inclusive) due to the inability of such Person to transmit or receive communications through the means specified therein, such Person may rely on telephonic notice for the transmission or receipt of such communications. In any case where such Person shall rely on telephone transmission or receipt, any communication made by telephone shall, as soon as possible thereafter, be followed by written confirmation thereof.

          §4.5. Submission and Contents of Competitive Bid Quotes.

     (a) Each Bank may, but shall be under no obligation to, submit a Competitive Bid Quote containing an offer or offers to make Competitive Bid Loans in response to any Competitive Bid Quote Request. Each Competitive Bid Quote must comply with the requirements of this §4.5 and must be submitted to the Administrative Agent by telex or facsimile transmission at its offices as specified in or pursuant to §22 not later than (x)

Subject to the provisions of §§10 and 11 hereof, any Competitive Bid Quote so made shall be irrevocable except with the written consent of the Administrative Agent given on the instructions of the Borrower.

     (b) Each Competitive Bid Quote shall be in substantially the form of Exhibit G hereto and shall in any case specify:

     (i) the proposed Drawdown Date;

     (ii) the principal amount of the Competitive Bid Loan for which each proposal is being made, which principal amount (w) may be greater than or less than the Commitment of the quoting Bank, (x) must be $5,000,000 or a larger multiple of $1,000,000, (y) may not exceed the aggregate principal amount of Competitive Bid Loans for which offers were requested and (z) may be subject to an aggregate limitation as to the principal amount of Competitive Bid Loans for which offers being made by such quoting Bank may be accepted;

     (iii) the Interest Period(s) for which Competitive Bid Quotes are being submitted;

     (iv) in the case of a Eurodollar Competitive Bid Loan, the margin above or below the applicable Eurodollar Rate (the “Competitive Bid Margin”) offered for each such Competitive Bid Loan, expressed as a percentage (specified to the nearest 1/10,000th of 1%) to be added to or subtracted from such Eurodollar Rate;

     (v) in the case of an Absolute Competitive Bid Loan, the rate of interest per annum (specified to the nearest 1/10,000th of 1%) (the “Competitive Bid Rate”) offered for each such Absolute Competitive Bid Loan; and

     (vi) the identity of the quoting Bank.

A Competitive Bid Quote may include up to five separate offers by the quoting Bank with respect to each Interest Period specified in the related Competitive Bid Quote Request.

     (c) Any Competitive Bid Quote shall be disregarded if it:

     (i) is not substantially in the form of Exhibit G hereto;

     (ii) contains qualifying, conditional or similar language;

     (iii) proposes terms other than or in addition to those set forth in the applicable Invitation for Competitive Bid Quotes; or

     (iv) arrives after the time set forth in §4.5(a) hereof.

          §4.6. Notice to Borrower. The Administrative Agent shall promptly notify the Borrower of the terms (x) of any Competitive Bid Quote submitted by a Bank that is in accordance with §4.5 and (y) of any Competitive Bid Quote that amends, modifies or is otherwise inconsistent with a previous Competitive Bid Quote submitted by such Bank with respect to the same Competitive Bid Quote Request. Any such subsequent Competitive Bid Quote shall be disregarded by the Administrative Agent unless such subsequent Competitive Bid Quote is submitted solely to correct a manifest error in such former Competitive Bid Quote. The Administrative Agent’s notice to the Borrower shall specify (A) the aggregate principal amount of Competitive Bid Loans for which offers have been received for each Interest Period specified in the related Competitive Bid Quote Request, (B) the respective principal amounts and Competitive Bid Margins or Competitive Bid Rates, as the case may be, so offered, and the identity of the respective Banks submitting such offers, and (C) if applicable, limitations on the aggregate principal amount of Competitive Bid Loans for which offers in any single Competitive Bid Quote may be accepted.

          §4.7. Acceptance and Notice by Borrower and Administrative Agent. Not later than 11:00 a.m. (New York time) on (x) the third Eurodollar Business Day prior to the proposed Drawdown Date, in the case of a Eurodollar Competitive Bid Loan or (y) the proposed Drawdown Date, in the case of an Absolute Competitive Bid Loan, the Borrower shall notify the Administrative Agent of its acceptance or non-acceptance of each Competitive Bid Quote in substantially the form of Exhibit H hereto. The Borrower may accept any Competitive Bid Quote in whole or in part; provided that:

     (i) the aggregate principal amount of each Competitive Bid Loan may not exceed the applicable amount set forth in the related Competitive Bid Quote Request;

     (ii) acceptance of offers may only be made on the basis of ascending Competitive Bid Margins or Competitive Bid Rates, as the case may be, and

     (iii) the Borrower may not accept any offer that is described in subsection 4.5(c) or that otherwise fails to comply with the requirements of this Agreement.

The Administrative Agent shall promptly notify each Bank which submitted a Competitive Bid Quote of the Borrower’s acceptance or non-acceptance thereof. At the request of any Bank which submitted a Competitive Bid Quote and with the consent of the Borrower, the Administrative Agent will promptly notify all Banks which submitted Competitive Bid Quotes of (a) the aggregate principal amount of, and (b) the range of Competitive Bid Rates or Competitive Bid Margins of, the accepted Competitive Bid Loans for each requested Interest Period.

          §4.8. Allocation by Administrative Agent. If offers are made by two or more Banks with the same Competitive Bid Margin or Competitive Bid Rate, as the case may be, for a greater aggregate principal amount than the amount in respect of which offers are accepted for the related Interest Period, the principal amount of Competitive Bid Loans in respect of which such offers are accepted shall be allocated by the Administrative Agent among such Banks as nearly as possible (in such multiples, not less than $1,000,000, as the Administrative Agent may deem appropriate) in proportion to the aggregate principal amounts of such offers. Determination by the Administrative Agent of the amounts of Competitive Bid Loans shall be conclusive in the absence of manifest error.

          §4.9. Funding of Competitive Bid Loans. If, on or prior to the Drawdown Date of any Competitive Bid Loan, the Total Commitment has not terminated in full and if, on such Drawdown Date, the applicable conditions of §§10 and 11 hereof are satisfied, the Bank or Banks whose offers the Borrower has accepted will fund each Competitive Bid Loan so accepted. Such Bank or Banks will make such Competitive Bid Loans by crediting the Administrative Agent for further credit to the Borrower’s specified account with the Administrative Agent, in immediately available funds not later than 1:00 p.m. (New York time) on such Drawdown Date.

          §4.10. Funding Losses. If, after acceptance of any Competitive Bid Quote pursuant to §4, the Borrower (i) fails to borrow any Competitive Bid Loan so accepted on the date specified therefor, or (ii) repays the outstanding amount of the Competitive Bid Loan prior to the last day of the Interest Period relating thereto, the Borrower shall indemnify the Bank making such Competitive Bid Quote or funding such Competitive Bid Loan against any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Bank to fund or maintain such unborrowed Competitive Bid Loans, including, without limitation compensation as provided in §5.8.

          §4.11. Repayment of Competitive Bid Loans; Interest. The principal of each Competitive Bid Loan shall become absolutely due and payable by the Borrower on the last day of the Interest Period relating thereto, and the Borrower hereby absolutely and unconditionally promises to pay to the Administrative Agent for the account of the relevant Banks at or before 1:00 p.m. (New York time) on the last day of the Interest Periods relating thereto the principal amount of all such Competitive Bid Loans, plus interest thereon at the applicable rates. The Competitive Bid Loans shall bear interest at the rate per annum specified in the applicable Competitive Bid Quotes. Interest on the Competitive Bid Loans shall be payable (a) on the last day of the applicable Interest Periods, and if any such Interest Period is longer than three months, also on the last day of the third month following the commencement of such Interest Period, and (b) on the Maturity Date for all Loans. Subject to the terms of this Agreement, the Borrower may make Competitive Bid Quote Requests with respect to new Borrowings of any amounts so repaid prior to the Maturity Date.

§5. PROVISIONS RELATING TO ALL LOANS AND LETTERS OF CREDIT.

          §5.1. Payments.

     (a) All payments of principal, interest, Reimbursement Obligations, fees (other than the Issuance Fee) and any other amounts due hereunder or under any of the other Loan Documents shall be made to the Administrative Agent at the Administrative Agent’s Account in immediately available funds by 11:00 a.m. (New York time) on any due date. Subject to the provisions of §29, if a payment is received by the Administrative Agent at or before 1:00 p.m. (New York time) on any Business Day, the Administrative Agent shall on the same Business Day transfer in immediately available funds, as applicable, to (1) each of the Banks, their pro rata portion of such payment in accordance with their respective Commitment Percentages, in the case of payments with respect to Syndicated Loans and Letters of Credit, (2) the Swing Line Bank in the case of payments with respect to Swing Line Loans, and (3) the appropriate Bank(s), in the case of payments with respect to Competitive Bid Loans. If such payment is received by the Administrative Agent after 1:00 p.m. (New York time) on any Business Day, such transfer shall be made by the Administrative Agent to the applicable Bank(s) on the next Business Day.

     (b) All payments by the Borrower and the Guarantor hereunder and under any of the other Loan Documents shall be made without recoupment, setoff or counterclaim and free and clear of and without deduction for any taxes, levies, imposts, duties, charges, fees, deductions, withholdings, compulsory loans, restrictions or conditions of any nature now or hereafter imposed or levied by any jurisdiction or any political subdivision thereof or taxing or other authority therein unless the Borrower or the Guarantor is compelled by law to make such deduction or withholding. If any such obligation is imposed upon the Borrower or the Guarantor with respect to any amount payable by it hereunder or under any of the other Loan Documents, the Borrower or the Guarantor, as the case may be, will pay to the Administrative Agent, for the account of the Banks or (as the case may be) the Administrative Agent, on the date on which such amount is due and payable hereunder or under such other Loan Document, such additional amount in Dollars as shall be necessary to enable the Banks or the Administrative Agent to receive the same net amount which the Banks or the Administrative Agent would have received on such due date had no such obligation been imposed upon the Borrower or the Guarantor. The Borrower and the Guarantor will deliver promptly to the Administrative Agent certificates or other valid vouchers for all taxes or other charges deducted from or paid with respect to payments made by it hereunder or under such other Loan Document.

     (c) Each Bank that is not incorporated or organized under the laws of the United States of America or a state thereof or the District of Columbia (a “Non-U.S. Bank”) agrees that, prior to the first date on which any payment is due to it hereunder, it will deliver to the Borrower and the Administrative Agent two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI or successor applicable form, as the case may be, certifying in each case that such Non-U.S. Bank is entitled to receive payments under this Agreement, without deduction or withholding of any United States federal income taxes. Each Non-U.S. Bank that so delivers a Form W-8BEN or W-8ECI pursuant to the preceding sentence further undertakes to deliver to each of the Borrower and the Administrative Agent two further copies of Form W-8BEN or W-8ECI or successor applicable form, or other manner of certification, as the case may be, on or before the date that any such letter

or form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower, and such extensions or renewals thereof as may reasonably be requested by the Borrower, certifying in the case of a Form W-8BEN or W-8ECI that such Non-U.S. Bank is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, unless in any such case an event (including, without limitation, any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Non-U.S. Bank from duly completing and delivering any such form with respect to it and such Non-U.S. Bank advises the Borrower that it is not capable of receiving payments without any deduction or withholding of United States federal income tax.

     (d) The Borrower shall not be required to pay any additional amounts to any Non-U.S. Bank in respect of United States Federal withholding tax pursuant to §17 to the extent that (i) the obligation to withhold amounts with respect to United States Federal withholding tax existed on the date such Non-U.S. Bank became a party to this Agreement or, with respect to payments to a different lending office designated by the Non-U.S. Bank as its applicable lending office (a “New Lending Office”), the date such Non-U.S. Bank designated such New Lending Office with respect to a Loan; provided, however, that this clause (i) shall not apply to any transferee or New Lending Office as a result of an assignment, transfer or designation made at the request of the Borrower; and provided further, however, that this clause (i) shall not apply to the extent the indemnity payment or additional amounts any transferee, or Bank through a New Lending Office, would be entitled to receive without regard to this clause (i) do not exceed the indemnity payment or additional amounts that the Person making the assignment or transfer to such transferee, or Bank making the designation of such New Lending Office, would have been entitled to receive in the absence of such assignment, transfer or designation; or (ii) the obligation to pay such additional amounts would not have arisen but for a failure by such Non-U.S. Bank to comply with the provisions of paragraph (b) above.

     (e) Notwithstanding the foregoing, each Bank agrees to use reasonable efforts (consistent with legal and regulatory restrictions) to change its lending office to avoid or to minimize any amounts otherwise payable under §17 in each case solely if such change can be made in a manner so that such Bank, in its sole determination, suffers no legal, economic or regulatory disadvantage.

          §5.2. Mandatory Repayments of the Loans. If at any time (including without limitation by reason of fluctuation in the rate of exchange between the Canadian Dollar and the U.S. Dollar) the sum of the outstanding principal amount of the Loans plus the Maximum Drawing Amount of all outstanding Letters of Credit exceeds the Total Commitment, whether by reduction of the Total Commitment or otherwise, then the Borrower shall immediately pay the amount of such excess to the Administrative Agent, (i) for application to the Loans, first to Syndicated Loans, then to Competitive Bid Loans, subject to §5.8, or (ii) if no Loans shall be outstanding, to be held by the Administrative Agent for the benefit of the Banks as collateral security for such excess Maximum Drawing Amount and the Borrower hereby grants a security interest in such amount to the Administrative Agent for the benefit of the

Banks; provided, however, that if the amount of cash collateral held by the Administrative Agent pursuant to this §5.2(a) exceeds the Maximum Drawing Amount required to be collateralized from time to time, the Administrative Agent shall return such excess to the Borrower.

          §5.3. Computations. Except as otherwise expressly provided herein, all computations of interest, Facility Fees, Letter of Credit Fees or other fees shall be based on a 360-day year and paid for the actual number of days elapsed, except that computations based on the Base Rate shall be based on a 365 or 366, as applicable, day year and paid for the actual number of days elapsed. Whenever a payment hereunder or under any of the other Loan Documents becomes due on a day that is not a Business Day, the due date for such payment shall be extended to the next succeeding Business Day, and interest shall accrue during such extension; provided that for any Interest Period for any Eurodollar Loan if such next succeeding Business Day falls in the next succeeding calendar month or after the Maturity Date, it shall be deemed to end on the next preceding Business Day.

          §5.4. Illegality; Inability to Determine Eurodollar Rate. Notwithstanding any other provision of this Agreement (other than §5.10), if (a) the introduction of, any change in, or any change in the interpretation of, any law or regulation applicable to any Bank or the Administrative Agent shall make it unlawful, or any central bank or other governmental authority having jurisdiction thereof shall assert that it is unlawful, for any Bank or the Administrative Agent to perform its obligations in respect of any Eurodollar Loans, or (b) if the Majority Banks or the Administrative Agent, as applicable, shall reasonably determine with respect to Eurodollar Loans that (i) by reason of circumstances affecting any Eurodollar interbank market, adequate and reasonable methods do not exist for ascertaining the Eurodollar Rate which would otherwise be applicable during any Interest Period, or (ii) deposits of Dollars in the relevant amount for the relevant Interest Period are not available to such Banks or the Administrative Agent in any Eurodollar interbank market, or (iii) the Eurodollar Rate does not or will not accurately reflect the cost to such Banks or the Administrative Agent of obtaining or maintaining the Eurodollar Loans during any Interest Period, then such Banks (through the Administrative Agent) or the Administrative Agent shall promptly give telephonic, telex or cable notice of such determination to the Borrower (which notice shall be conclusive and binding upon the Borrower). Upon such notification, the obligation of the Banks and the Administrative Agent to make Eurodollar Loans shall be suspended until the Banks or the Administrative Agent, as the case may be, determine that such circumstances no longer exist, and to the extent permitted by law the outstanding Eurodollar Loans shall continue to bear interest at the applicable rate based on the Eurodollar Rate until the end of the applicable Interest Period, and thereafter shall be deemed converted to Base Rate Loans in equal principal amounts to such former Eurodollar Loans.

          §5.5. Additional Costs, Etc. If any present or future applicable law (which expression, as used herein, includes statutes, rules and regulations thereunder and interpretations thereof by any competent court or by any governmental or other regulatory body or official charged with the administration or the interpretation thereof and requests, directives, instructions and notices at any time or from time to time hereafter made upon or otherwise issued to any Bank by any central bank or other fiscal, monetary or other authority, whether or not having the force of law) shall:

     (a) subject such Bank to any tax, levy, impost, duty, charge, fee, deduction or withholding of any nature with respect to this Agreement, the other Loan Documents, such Bank’s Commitment or the Loans (other than taxes based upon or measured by the income or profits of such Bank imposed by the jurisdiction of its incorporation or organization, or the location of its lending office); or

     (b) materially change the basis of taxation (except for changes in taxes on income or profits of such Bank imposed by the jurisdiction of its incorporation or organization, or the location of its lending office) of payments to such Bank of the principal or of the interest on any Loans or any other amounts payable to such Bank under this Agreement or the other Loan Documents; or

     (c) except as provided in §5.6 or as otherwise reflected in the Base Rate, the Eurodollar Rate, or the applicable rate for Competitive Bid Loans, impose or increase or render applicable (other than to the extent specifically provided for elsewhere in this Agreement) any special deposit, reserve, assessment, liquidity, capital adequacy or other similar requirements (whether or not having the force of law) against assets held by, or deposits in or for the account of, or loans by, or commitments of, an office of any Bank with respect to this Agreement, the other Loan Documents, such Bank’s Commitment or the Loans; or

     (d) impose on such Bank any other conditions or requirements with respect to this Agreement, the other Loan Documents, the Loans, such Bank’s Commitment or any class of loans or commitments of which any of the Loans or such Bank’s Commitment forms a part, and the result of any of the foregoing is:

     (i) to increase the cost to such Bank of making, funding, issuing, renewing, extending or maintaining the Loans or such Bank’s Commitment or issuing or participating in Letters of Credit;

     (ii) to reduce the amount of principal, interest or other amount payable to such Bank hereunder on account of such Bank’s Commitment, the Loans or the Reimbursement Obligations; or

     (iii) to require such Bank to make any payment or to forego any interest or other sum payable hereunder, the amount of which payment or foregone interest or other sum is calculated by reference to the gross amount of any sum receivable or deemed received by such Bank from the Borrower hereunder,

then, and in each such case, the Borrower will, upon demand made by such Bank at any time and from time to time as often as the occasion therefor may arise (which demand shall be accompanied by a statement setting forth the basis of such demand which shall be conclusive absent manifest error), pay such reasonable additional amounts as will be sufficient to compensate such Bank for such additional costs, reduction, payment or foregone interest or other sum; provided that the determination and allocation of amounts, if any, claimed by any Bank under this Section 5.5 are made on a reasonable basis in a manner consistent with such Bank’s treatment of customers of such Bank that such Bank considers, in its reasonable

discretion, to be similar to the Borrower and having generally similar provisions in their agreements with such Bank.

          §5.6. Capital Adequacy. If any Bank shall have determined that, after the date hereof, (a) the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change in any such 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 any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, or (b) compliance by such Bank or the Administrative Agent or any corporation controlling such Bank or the Administrative Agent with any law, governmental rule, regulation, policy, guideline or directive (whether or not having the force of law) of any such entity regarding capital adequacy, has or would have the effect of reducing the rate of return on capital of such Bank (or any corporation controlling such Bank) as a consequence of such Bank’s obligations hereunder to a level below that which such Bank (or any corporation controlling such Bank) could have achieved but for such adoption, change, request or directive (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Bank to be material, then from time to time, within 15 days after demand by such Bank, the Borrower shall pay to such Bank such additional amount or amounts as will, in such Bank’s reasonable determination, fairly compensate such Bank (or any corporation controlling such Bank) for such reduction. Each Bank shall allocate such cost increases among its customers in good faith and on an equitable basis.

          §5.7. Certificate. A certificate setting forth the additional amounts payable pursuant to §5.5 or §5.6 and a reasonable explanation of such amounts which are due, submitted by any Bank to the Borrower, shall be conclusive, absent manifest error, that such amounts are due and owing; provided that no Bank shall be entitled to additional amounts with respect to events or circumstances occurring more than one hundred and twenty (120) days prior to the delivery of such certificate.

          §5.8. Eurodollar and Competitive Bid Indemnity. The Borrower agrees to indemnify the Banks and the Administrative Agent and to hold them harmless from and against any reasonable loss, cost or expense that any such Bank and the Administrative Agent may sustain or incur as a consequence of (a) the default by the Borrower in payment of the principal amount of or any interest on any Eurodollar Loans or Competitive Bid Loans as and when due and payable, including any such loss or expense arising from interest or fees payable by any Bank or the Administrative Agent to lenders of funds obtained by it in order to maintain its Eurodollar Loans or Competitive Bid Loans, (b) the default by the Borrower in making a Borrowing of a Eurodollar Loan or Competitive Bid Loan or conversion of a Eurodollar Loan or a prepayment of a Eurodollar or Competitive Bid Loan after the Borrower has given (or is deemed to have given) a Syndicated Loan Request, a notice pursuant to §2.7 or a Notice of Acceptance/Rejection of Competitive Bid Quote(s), or a notice pursuant to §2.10, and (c) the making of any payment of a Eurodollar Loan or Competitive Bid Loan, or the making of any conversion of any Eurodollar Loan to a Base Rate Loan, on a day that is not the last day of the applicable Interest Period with respect thereto. Such loss, cost, or reasonable expense shall include an amount equal to the excess, if any, as reasonably determined by each Bank of (i) its cost of obtaining the funds for (A) the Eurodollar Loan being paid, prepaid,

converted, not converted, reallocated, or not borrowed, as the case may be (based on the Eurodollar Rate), or (B) the Competitive Bid Loan being paid, prepaid, or not borrowed, as the case may be (based on the applicable interest rate) for the period from the date of such payment, prepayment, conversion, or failure to borrow or convert, as the case may be, to the last day of the Interest Period for such Loan (or, in the case of a failure to borrow, the Interest Period for the Loan which would have commenced on the date of such failure to borrow) over (ii) the amount of interest (as reasonably determined by such Bank) that would be realized by such Bank in reemploying the funds so paid, prepaid, converted, or not borrowed, converted, or prepaid for such period or Interest Period, as the case may be, which determinations shall be conclusive absent manifest error.

          §5.9. Interest on Overdue Amounts. Overdue principal and (to the extent permitted by applicable law) interest on the Loans and all other overdue amounts payable hereunder or under any of the other Loan Documents shall bear interest compounded monthly and payable on demand at a rate per annum equal to the Applicable Base Rate plus 2% per annum, until such amount shall be paid in full (after as well as before judgment).

          §5.10. Interest Limitation. Notwithstanding any other term of this Agreement, any other Loan Document or any other document referred to herein or therein, the maximum amount of interest which may be charged to or collected from any Person liable hereunder by any Bank shall be absolutely limited to, and shall in no event exceed, the maximum amount of interest which could lawfully be charged or collected by such Bank under applicable laws (including, to the extent applicable, the provisions of §5197 of the Revised Statutes of the United States of America, as amended, and 12 U.S.C. §85, as amended, and without prejudice to the first sentence of §26 hereof).

          §5.11. Reasonable Efforts to Mitigate. Each Bank agrees that as promptly as practicable after it becomes aware of the occurrence of an event or the existence of a condition that would cause it to be affected under §§5.4, 5.5 or 5.6, such Bank will give notice thereof to the Borrower, with a copy to the Administrative Agent and, to the extent so requested by the Borrower and not inconsistent with such Bank’s internal policies, such Bank shall use reasonable efforts and take such actions as are reasonably appropriate if as a result thereof the additional moneys which would otherwise be required to be paid to such Bank pursuant to such sections would be materially reduced, or the illegality or other adverse circumstances which would otherwise require a conversion of such Loans or result in the inability to make such Loans pursuant to such sections would cease to exist, and in each case if, as determined by such Bank in its sole discretion, the taking of such actions would not adversely affect such Loans or such Bank or otherwise be disadvantageous to such Bank.

          §5.12. Replacement of Banks. If any Bank (an “Affected Bank”) (1) makes demand upon the Borrower for (or if the Borrower is otherwise required to pay) amounts pursuant to §§5.5 or 5.6, (ii) is unable to make or maintain Eurodollar Loans as a result of a condition described in §5.4 or (iii) defaults in its obligation to make Loans or to participate in Letters of Credit in accordance with the terms of this Agreement (such Bank being referred to as a “Defaulting Bank”), the Borrower may, within 90 days of receipt of such demand, notice (or the occurrence of such other event causing the Borrower to be required to pay such compensation or causing §5.4 to be applicable), or default, as the case may be, by

notice (a “Replacement Notice”) in writing to the Administrative Agent and such Affected Bank (A) request the Affected Bank to cooperate with the Borrower in obtaining a replacement bank satisfactory to the Administrative Agent and the Borrower (the “Replacement Bank”) as provided herein, but none of such Banks shall be under an obligation to find a Replacement Bank; (B) request the non-Affected Banks to acquire and assume all of the Affected Bank’s Loans and Commitment, and to participate in Letters of Credit as provided herein, but none of such Banks shall be under an obligation to do so; or (C) designate a Replacement Bank reasonably satisfactory to the Administrative Agent. If any satisfactory Replacement Bank shall be obtained, and/or any of the non-Affected Banks shall agree to acquire and assume all of the Affected Bank’s Loans and Commitment, and to participate in Letters of Credit, then such Affected Bank shall, so long as no Event of Default shall have occurred and be continuing, assign, in accordance with §20, all of its Commitment, Loans, and other rights and obligations under this Agreement and all other Loan Documents to such Replacement Bank or non-Affected Banks, as the case may be, in exchange for payment of the principal amount so assigned and all interest and fees accrued on the amount so assigned, plus all other Obligations then due and payable to the Affected Bank; provided, however, that (x) such assignment shall be without recourse, representation or warranty and shall be on terms and conditions reasonably satisfactory to such Affected Bank and such Replacement Bank and/or non-Affected Banks, as the case may be, and (y) prior to any such assignment, the Borrower shall have paid to such Affected Bank all amounts properly demanded and unreimbursed under §§5.5, 5.6 and 5.8. Upon the effective date of such assignment, such Replacement Bank shall become a “Bank” for all purposes under this Agreement and the other Loan Documents.

          §5.13. Advances by Administrative Agent. Unless the Administrative Agent shall have been notified in writing by any Bank prior to a borrowing hereunder that such Bank will not make the amount that would constitute its allocable share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Bank is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the borrowing date therefor, such Bank shall pay to the Administrative Agent, on demand, such amount with interest thereon at a rate equal to the daily average Federal Funds Rate for the period until such Bank makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Bank with respect to any amounts owing under this Section shall be conclusive in the absence of manifest error. If such Bank’s Commitment Percentage of such borrowing is not made available to the Administrative Agent by such Bank within three Business Days of such borrowing date, the Administrative Agent shall be entitled to recover such amount with interest thereon at the rate per annum applicable to such Loan hereunder, on demand, from the Borrower.

§6. REPRESENTATIONS AND WARRANTIES. The Borrower (and the Guarantor, where applicable) represents and warrants to the Banks that:

          §6.1. Corporate Authority.

- 42 -

     (a) Incorporation; Good Standing.

     (b) Authorization. The execution, delivery and performance of its Loan Documents and the transactions contemplated hereby and thereby (i) are within the corporate authority of the Borrower and the Guarantor, (ii) have been duly authorized by all necessary corporate proceedings on the part of each of the Borrower and the Guarantor, (iii) do not conflict with or result in any breach or contravention of any provision of law, statute, rule or regulation to which any of the Borrower or the Guarantor or any of their Subsidiaries is subject, (iv) do not contravene any judgment, order, writ, injunction, license or permit applicable to the Borrower, the Guarantor or any of their Subsidiaries so as to have a Material Adverse Effect, and (v) do not conflict with any provision of the corporate charter or bylaws of the Borrower, the Guarantor or any Significant Subsidiary or any agreement or other instrument binding upon the Borrower, the Guarantor or any of their Significant Subsidiaries, except for those conflicts with any such agreement or instrument which could not reasonably be expected to have a Material Adverse Effect.

     (c) Enforceability. The execution, delivery and performance of the Loan Documents by the Borrower and the Guarantor will result in valid and legally binding obligations of the Borrower and the Guarantor enforceable against them in accordance with the respective terms and provisions hereof and thereof, except as enforceability is limited by bankruptcy, insolvency, reorganization, moratorium or other laws relating to or affecting generally the enforcement of creditors’ rights generally and general principles of equity.

          §6.2. Governmental and Other Approvals. The execution, delivery and performance of the Loan Documents by the Borrower and the Guarantor and the consummation by the Borrower and the Guarantor of the transactions contemplated hereby and thereby do not require any approval or consent of, or filing with, any governmental agency or authority or other third party other than those already obtained and those required after the date hereof in connection with the Borrower’s performance of the covenants contained in §§7, 8 and 9 hereof.

          §6.3. Title to Properties; Leases. The Borrower and its Subsidiaries own all of the assets reflected in the consolidated balance sheet as at the Interim Balance Sheet Date or acquired since that date (except property and assets operated under Capital Leases or sold or otherwise disposed of in the ordinary course of business since that date), subject to no Liens except Permitted Liens.

          §6.4. Financial Statements; Solvency.

     (a) There have been furnished to the Banks consolidated balance sheets of the Borrower dated the Balance Sheet Date and consolidated statements of operations for the fiscal periods then ended, certified by the Accountants. In addition, there have been furnished to the Banks consolidated balance sheets of the Borrower and its Subsidiaries dated the Interim Balance Sheet Date and the related consolidated statements of operations for the fiscal quarter ending on the Interim Balance Sheet Date. All said balance sheets and statements of operations have been prepared in accordance with GAAP (but, in the case of any of such financial statements which are unaudited, only to the extent GAAP is applicable to interim unaudited reports), and fairly present, in all material respects, the financial condition of the Borrower on a consolidated basis as at the close of business on the dates thereof and the results of operations for the periods then ended, subject, in the case of unaudited interim financial statements, to changes resulting from audit and normal year-end adjustments and to the absence of complete footnotes. There are no contingent liabilities of the Borrower and its Subsidiaries involving material amounts, known to the officers of the Borrower or the Guarantor, which have not been disclosed in said balance sheets and the related notes thereto or otherwise in writing to the Banks.

     (b) The Borrower on a consolidated basis (both before and after giving effect to the transactions contemplated by this Agreement) is solvent (i.e., it has assets having a fair value in excess of the amount required to pay its probable liabilities on its existing debts as they become absolute and matured) and has, and expects to have, the ability to pay its debts from time to time incurred in connection therewith as such debts mature.

          §6.5. No Material Changes, Etc. Since the Balance Sheet Date, there have been no material adverse changes in the consolidated financial condition, business, assets or liabilities (contingent or otherwise) of the Borrower and its Subsidiaries, taken as a whole, other than changes in the ordinary course of business which have not had a Material Adverse Effect.

          §6.6. Franchises, Patents, Copyrights, Etc. The Borrower and each of its Subsidiaries possess all franchises, patents, copyrights, trademarks, trade names, licenses and permits, and rights in respect of the foregoing, adequate for the conduct of their business substantially as now conducted (other than those the absence of which would not have a Material Adverse Effect) without known conflict with any rights of others other than a conflict which would not have a Material Adverse Effect.

          §6.7. Litigation. Except as set forth on Schedule 6.7 or in the Disclosure Documents, there are no actions, suits, proceedings or investigations of any kind pending or, to the knowledge of the Borrower, threatened against the Borrower or any of its Subsidiaries before any court, tribunal or administrative agency or board which, either in any case or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

          §6.8. No Materially Adverse Contracts, Etc. Neither the Borrower nor any of its Subsidiaries is subject to any charter, corporate or other legal restriction, or any judgment, decree, order, rule or regulation which in the judgment of the Borrower’s or such Subsidiary’s

officers has or could reasonably be expected in the future to have a Material Adverse Effect. Neither the Borrower nor any of its Subsidiaries is a party to any contract or agreement which in the judgment of the Borrower’s or its Subsidiary’s officers has or could reasonably be expected to have any Material Adverse Effect, except as otherwise reflected in adequate reserves as required by GAAP.

          §6.9. Compliance With Other Instruments, Laws, Etc. Neither the Borrower nor any of its Subsidiaries is (a) violating any provision of its charter documents or bylaws or (b) violating any agreement or instrument to which any of them may be subject or by which any of them or any of their properties may be bound or any decree, order, judgment, or any statute, license, rule or regulation, in a manner which could (in the case of such agreements or such instruments) reasonably be expected to result in a Material Adverse Effect.

          §6.10. Tax Status. The Borrower and its Subsidiaries have filed all federal, state, provincial and territorial income and all other tax returns, reports and declarations (or obtained extensions with respect thereto) required by applicable law to be filed by them (unless and only to the extent that the Borrower or such Subsidiary has set aside on its books provisions reasonably adequate for the payment of all unpaid and unreported taxes as required by GAAP); and have paid all taxes and other governmental assessments and charges (other than taxes, assessments and other governmental charges imposed by jurisdictions other than the United States, Canada or any political subdivision thereof which in the aggregate are not material to the financial condition, business or assets of the Borrower or such Subsidiary on an individual basis or of the Borrower on a consolidated basis) that are material in amount, shown or determined to be due on such returns, reports and declarations, except those being contested in good faith; and, as required by GAAP, have set aside on their books provisions reasonably adequate for the payment of all taxes for periods subsequent to the periods to which such returns, reports or declarations apply. Except to the extent contested in the manner permitted in the preceding sentence, there are no unpaid taxes in any material amount claimed by the taxing authority of any jurisdiction to be due and owing by the Borrower or any Subsidiary, nor do the officers of the Borrower or any of its Subsidiaries know of any basis for any such claim.

          §6.11. No Event of Default. No Default or Event of Default has occurred hereunder and is continuing.

          §6.12. Investment Company Act. Neither the Borrower nor any of its Subsidiaries is a “registered investment company”, or an “affiliated company” or a “principal underwriter” of a “registered investment company”, as such terms are defined in the Investment Company Act of 1940.

          §6.13. Absence of Financing Statements, Etc. Except as permitted by §8.1 of this Agreement, there is no Indebtedness senior to the Obligations, and except for Permitted Liens, there are no Liens, or any effective financing statement, security agreement, chattel mortgage, real estate mortgage or other document filed or recorded with any filing records, registry, or other public office, which purports to cover, affect or give notice of any present or possible future Lien on any assets or property of the Borrower or any of its Subsidiaries or right thereunder.

          §6.14. Employee Benefit Plans.

          §6.14.1. In General. Each Employee Benefit Plan has been maintained and operated in compliance with the provisions of ERISA and, to the extent applicable, the Code, including but not limited to the provisions thereunder respecting prohibited transactions. Promptly upon the request of any Bank or the Administrative Agent, the Borrower will furnish to the Administrative Agent the most recently completed annual report, Form 5500, with all required attachments, and actuarial statement required to be submitted under §103(d) of ERISA, with respect to each Guaranteed Pension Plan.

          §6.14.2. Terminability of Welfare Plans. Under each Employee Benefit Plan which is an employee welfare benefit plan within the meaning of §3(1) or §3(2)(B) of ERISA, no benefits are due unless the event giving rise to the benefit entitlement occurs prior to plan termination (except as required by Title 1, Part 6 of ERISA). The Borrower or an ERISA Affiliate, as appropriate, may terminate each such Plan at any time (or at any time subsequent to the expiration of any applicable bargaining agreement) in the discretion of the Borrower or such ERISA Affiliate without material liability to any Person.

          §6.14.3. Guaranteed Pension Plans. Each contribution required to be made to a Guaranteed Pension Plan, whether required to be made to avoid the incurrence of an accumulated funding deficiency, the notice or lien provisions of §302(f) of ERISA, or otherwise, has been timely made. No waiver of an accumulated funding deficiency or extension of amortization periods has been received with respect to any Guaranteed Pension Plan. No liability to the PBGC (other than required insurance premiums, all of which have been paid) has been incurred by the Borrower or any ERISA Affiliate with respect to any Guaranteed Pension Plan (other than Terminated Plans) and there has not been any ERISA Reportable Event, or any other event or condition which presents a material risk of termination of any Guaranteed Pension Plan by the PBGC. Other than with respect to the Terminated Plans, based on the latest valuation of each Guaranteed Pension Plan (which in each case occurred within twelve months of the date of this representation), and on the actuarial methods and assumptions employed for that valuation, the aggregate benefit liabilities of all such Guaranteed Pension Plans within the meaning of §4001 of ERISA did not exceed the aggregate value of the assets of all such Guaranteed Pension Plans, disregarding for this purpose the benefit liabilities and assets of any Guaranteed Pension Plan with assets in excess of benefit liabilities.

          §6.14.4. Multiemployer Plans. Neither the Borrower nor any ERISA Affiliate has incurred any material liability (including secondary liability) to any Multiemployer Plan as a result of a complete or partial withdrawal from such Multiemployer Plan under §4201 of ERISA or as a result of a sale of assets described in §4204 of ERISA. Neither the Borrower nor any ERISA Affiliate has been notified that any Multiemployer Plan is in reorganization or insolvent under and within the meaning of §4241 or §4245 of ERISA or that any Multiemployer Plan intends to terminate or has been terminated under §4041A of ERISA.

          §6.15. Environmental Compliance. The Borrower and its Subsidiaries have taken all steps that they have deemed reasonably necessary to investigate the past and present condition and usage of the Real Property and the operations conducted by the Borrower and its Subsidiaries and, based upon such diligent investigation, have determined that, except as set forth on Schedule 6.15 or in the Disclosure Documents:

     (a) Neither the Borrower, its Significant Subsidiaries, nor any operator of their properties, is in violation, or alleged violation, of any judgment, decree, order, law, permit, license, rule or regulation pertaining to environmental matters, including without limitation, those arising under the Resource Conservation and Recovery Act (“RCRA”), the Comprehensive Environmental Response, Compensation and Liability Act of 1980 as amended (“CERCLA”), the Superfund Amendments and Reauthorization Act of 1986 (“SARA”), the Federal Clean Water Act, the Federal Clean Air Act, the Toxic Substances Control Act, or any applicable international, federal, state, provincial, territorial or local statute, regulation, ordinance, order or decree relating to health, safety, waste transportation or disposal, or the environment (the “Environmental Laws”), which violation, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

     (b) Except with respect to any such matters that could not reasonably be expected to have a Material Adverse Effect, neither the Borrower nor any of its Significant Subsidiaries has received notice from any third party including, without limitation: any federal, state, provincial, territorial or local governmental authority, (i) that any one of them has been identified by the United States Environmental Protection Agency (“EPA”) as a potentially responsible party under CERCLA with respect to a site listed on the National Priorities List, 40 C.F.R. Part 300 Appendix B; (ii) that any hazardous waste, as defined by 42 U.S.C. §6903(5), any hazardous substances as defined by 42 U.S.C. §9601(14), any pollutant or contaminant as defined by 42 U.S.C. §9601(33) or any toxic substance, oil or hazardous materials or other chemicals or substances regulated by any Environmental Laws, excluding household hazardous waste (“Hazardous Substances”), which any one of them has generated, transported or disposed of, has been found at any site at which a federal, state, provincial, territorial or local agency or other third party has conducted or has ordered that the Borrower or any of its Significant Subsidiaries conduct a remedial investigation, removal or other response action pursuant to any Environmental Law; or (iii) that it is or shall be a named party to any claim, action, cause of action, complaint, legal or administrative proceeding arising out of any third party’s incurrence of costs, expenses, losses or damages of any kind whatsoever in connection with the Release of Hazardous Substances.

     (c) Except for those occurrences or situations that could not reasonably be expected to have a Material Adverse Effect, (i) no portion of the Real Property or other assets of the Borrower and its Significant Subsidiaries has been used for the handling, processing, storage or disposal of Hazardous Substances except in accordance with applicable Environmental Laws; (ii) in the course of any activities conducted by the Borrower, its Significant Subsidiaries, or operators of the Real Property or other assets of the Borrower and its Significant Subsidiaries, no Hazardous Substances have been generated or are being used on such properties

except in accordance with applicable Environmental Laws; (iii) there have been no unpermitted Releases or threatened Releases of Hazardous Substances on, upon, into or from the Real Property or other assets of the Borrower or its Significant Subsidiaries; and (iv) any Hazardous Substances that have been generated on the Real Property or other assets of the Borrower or its Significant Subsidiaries have been transported offsite only by carriers having an identification number issued by the EPA, treated or disposed of only by treatment or disposal facilities maintaining valid permits as required under applicable Environmental Laws, which transporters and facilities have been and are, to the Borrower’s knowledge, operating in compliance with such permits and applicable Environmental Laws.

          §6.16. Disclosure. No representation or warranty made by the Borrower or the Guarantor in this Agreement or in any agreement, instrument, document, certificate, or financial statement furnished to the Banks or the Administrative Agent by or on behalf of or at the request of the Borrower and the Guarantor in connection with any of the transactions contemplated by the Loan Documents contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained therein, taken as a whole, not misleading in light of the circumstances in which they are made.

          §6.17. Permits and Governmental Authority. All permits (other than those the absence of which could not reasonably be expected to have a Material Adverse Effect) required for the construction and operation of all landfills currently owned or operated by the Borrower or any of its Significant Subsidiaries have been obtained and remain in full force and effect and are not subject to any appeals or further proceedings or to any unsatisfied conditions that may allow material modification or revocation. Neither the Borrower nor any of its Subsidiaries, nor, to the knowledge of the Borrower, the holder of such permits is in violation of any such permits, except for any violation which could not reasonably be expected to have a Material Adverse Effect.

§7. AFFIRMATIVE COVENANTS OF THE BORROWER. The Borrower agrees that, so long as any Obligation or Letter of Credit is outstanding or the Banks have any obligation to make Loans or any Issuing Bank has any obligation to issue, extend or renew any Letter of Credit hereunder, or the Banks have any obligations to reimburse any Issuing Bank for drawings honored under any Letter of Credit, it shall, and shall cause its Subsidiaries to, comply with the following covenants:

          §7.1. Punctual Payment. The Borrower will duly and punctually pay or cause to be paid the principal of and interest on the Loans, all Reimbursement Obligations, fees and other amounts provided for in this Agreement and the other Loan Documents, all in accordance with the terms of this Agreement and such other Loan Documents.

          §7.4. Financial Statements, Certificates and Information. The Borrower will deliver to the Banks:

In addition, simultaneously therewith, the Borrower shall provide the Banks with a written statement from such Accountants to the effect that they have read a copy of this Agreement, and that, in making the examination necessary to said certification, they have obtained no knowledge of any Default or Event of Default, or, if such Accountants shall have obtained knowledge of any then existing Default or Event of Default they shall disclose in such statement any such Default or Event of Default;

     (b) as soon as practicable, but in any event not later than 60 days after the end of each of the first three fiscal quarters of each fiscal year of the Borrower, copies of the consolidated balance sheet and statement of operations of the Borrower as at the end of such quarter, subject to year-end adjustments, and the related consolidated statement of cash flows, all in reasonable detail and prepared in accordance with GAAP (to the extent GAAP is applicable to interim unaudited financial statements) with a certification by the principal financial or accounting officer of the Borrower (the “CFO or the CAO”) that the consolidated financial statements are prepared in accordance with GAAP (to the extent GAAP is applicable to interim unaudited financial statements) and fairly present, in all material respects, the consolidated financial condition of the Borrower as at the close of business on the date thereof and the results of operations for the period then ended, subject to year-end adjustments and the exclusion of detailed footnotes;

     (c) simultaneously with the delivery of the financial statements referred to in (a) and (b) above, a certificate in the form of Exhibit C hereto (the “Compliance Certificate”) signed by the CFO or the CAO or the Borrower’s corporate treasurer, stating that the Borrower and its Subsidiaries are in compliance with the covenants contained in §§7, 8 and 9 hereof as of the end of the applicable period and setting forth in reasonable detail computations evidencing such compliance with respect to the covenants contained in §9 hereof and that no Default or Event of Default exists, provided that if the Borrower shall at the time of issuance of such Compliance Certificate or at any other time obtain knowledge of any Default or Event of Default, the Borrower shall include in such certificate or otherwise deliver forthwith to the Banks a certificate specifying the nature

and period of existence thereof and what action the Borrower proposes to take with respect thereto;

     (d) promptly following the filing or mailing thereof, copies of all material of a financial nature filed with the Securities and Exchange Commission or sent to the Borrower’s and its Subsidiaries’ stockholders generally; and

     (e) from time to time such other financial data and other information as any of the Banks may reasonably request through the Administrative Agent.

     The Borrower hereby authorizes each Bank to disclose any information obtained pursuant to this Agreement to all appropriate governmental regulatory authorities where required by law; provided, however, this authorization shall not be deemed to be a waiver of any rights to object to the disclosure by the Banks of any such information which the Borrower has or may have under the federal Right to Financial Privacy Act of 1978, as in effect from time to time, except as to matters specifically permitted therein.

          §7.5. Existence and Conduct of Business. The Borrower will, and will cause each Significant Subsidiary to, do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights and franchises; and effect and maintain its foreign qualifications (except where the failure of the Borrower or any Significant Subsidiary to remain so qualified could not reasonably be expected to have a Material Adverse Effect), licensing, domestication or authorization, except as any of the foregoing may be terminated by its Board of Directors in the exercise of its reasonable judgment; provided that such termination could not reasonably be expected to have a Material Adverse Effect. The Borrower will not, and will cause its Subsidiaries not to, become obligated under any contract or binding arrangement which, at the time it was entered into, could reasonably be expected to have a Material Adverse Effect. The Borrower will, and will cause each Subsidiary to, continue to engage primarily in any of the businesses now conducted by the Borrower and its Subsidiaries and in related, complementary or supplemental businesses, and any additional businesses acquired pursuant to the terms of §8.4(a) hereunder.

          §7.6. Maintenance of Properties. The Borrower will, and will cause its Significant Subsidiaries to, cause all material properties used or useful in the conduct of their businesses to be maintained and kept in good condition, repair and working order (ordinary wear and tear excepted) and supplied with all necessary equipment and cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Borrower and its Significant Subsidiaries may be necessary so that the businesses carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this section shall prevent the Borrower or any of its Subsidiaries from discontinuing the operation and maintenance of any of its properties if such discontinuance is, in the judgment of the Borrower or such Subsidiary, desirable in the conduct of its or their business and which could not reasonably be expected to have a Material Adverse Effect.

          §7.7. Insurance. The Borrower will, and will cause its Subsidiaries to, maintain insurance of the kinds, covering the risks (other than risks arising out of or in any way connected with personal liability of any officers and directors thereof) and in the relative

proportionate amounts usually carried by reasonable and prudent companies conducting businesses similar to that of the Borrower and its Subsidiaries, in amounts substantially similar to the existing coverage maintained by the Borrower and its Subsidiaries. Such insurance shall be with financially sound and reputable insurance companies (including captive insurance companies), funds or underwriters, or may be pursuant to self-insurance plans. In addition, the Borrower will furnish from time to time, upon the Administrative Agent’s request, a summary of the insurance coverage of the Borrower and its Subsidiaries, which summary shall be in form and substance satisfactory to the Administrative Agent and, if requested by the Administrative Agent, will furnish to the Administrative Agent copies of the applicable policies.

          §7.8. Taxes. The Borrower will, and will cause its Subsidiaries to, duly pay and discharge, or cause to be paid and discharged, before the same shall become overdue, all taxes, assessments and other governmental charges imposed upon it and its real properties, sales and activities, or any part thereof, or upon the income or profits therefrom, as well as all claims for labor, materials, or supplies, which if unpaid might by law become a Lien upon any of its property; provided, however, that any such tax, assessment, charge, levy or claim need not be paid if the failure to do so (either individually, or in the aggregate for all such failures) could not reasonably be expected to have a Material Adverse Effect and the validity or amount thereof shall currently be contested in good faith by appropriate proceedings and if the Borrower or such Subsidiary shall have set aside on its books adequate reserves with respect thereto as required by GAAP; and provided, further, that the Borrower or such Subsidiary will pay all such taxes, assessments, charges, levies or claims prior to the foreclosure on any Lien which may have attached as security therefor.

          §7.9. Inspection of Properties, Books and Contracts. The Borrower will, and will cause its Significant Subsidiaries to, permit the Administrative Agent or any Bank or any of their designated representatives, upon reasonable notice, to visit and inspect any of the properties of the Borrower and its Significant Subsidiaries, to examine the books of account of the Borrower and its Significant Subsidiaries, or contracts (and to make copies thereof and extracts therefrom), and to discuss the affairs, finances and accounts of the Borrower and its Significant Subsidiaries with, and to be advised as to the same by, their officers, all at such times and intervals as may be reasonably requested.

          §7.10. Compliance with Laws, Contracts, Licenses and Permits; Maintenance of Material Licenses and Permits. The Borrower will, and will cause each Subsidiary to, (i) comply with the provisions of its charter documents and by-laws; (ii) comply with all agreements and instruments by which it or any of its properties may be bound except where noncompliance could not reasonably be expected to have a Material Adverse Effect; (iii) comply with all applicable laws and regulations (including Environmental Laws), decrees, orders, judgments, licenses and permits, including, without limitation, all environmental permits (“Applicable Requirements”), except where noncompliance with such Applicable Requirements could not reasonably be expected to have a Material Adverse Effect; (iv) maintain all operating permits for all landfills now owned or hereafter acquired, except where the failure to do so could not reasonably be expected to have a Material Adverse Effect; and (v) dispose of hazardous waste only at licensed disposal facilities operating, to the Borrower’s knowledge, in compliance with Environmental Laws, except where the failure to do so could not reasonably be expected to have a Material Adverse Effect. If at any time any authorization, consent, approval, permit or

license from any officer, agency or instrumentality of any government shall become necessary or required in order that the Borrower or any Significant Subsidiary may fulfill any of its obligations hereunder or under any other Loan Document, the Borrower will immediately take or cause to be taken all reasonable steps within the power of the Borrower or such Significant Subsidiary to obtain such authorization, consent, approval, permit or license and furnish the Banks with evidence thereof.

          §7.11. Environmental Indemnification. The Borrower covenants and agrees that it will indemnify and hold the Banks, the Issuing Banks and the Administrative Agent and their respective affiliates, and each of the representatives, agents and officers of each of the foregoing, harmless from and against any and all claims, expense, damage, loss or liability incurred by the Banks, the Issuing Banks or the Administrative Agent (including all reasonable costs of legal representation incurred by the Banks, the Issuing Banks or the Administrative Agent) relating to (a) any Release or threatened Release of Hazardous Substances on the Real Property; (b) any violation of any Environmental Laws or Applicable Requirements with respect to conditions at the Real Property or other assets of the Borrower or its Subsidiaries, or the operations conducted thereon; or (c) the investigation or remediation of offsite locations at which the Borrower, any of its Subsidiaries, or their predecessors are alleged to have directly or indirectly Disposed of Hazardous Substances. It is expressly acknowledged by the Borrower that this covenant of indemnification shall survive the payment of the Loans and Reimbursement Obligations and satisfaction of all other Obligations hereunder and shall inure to the benefit of the Banks, the Issuing Banks, the Administrative Agent and their affiliates, successors and assigns.

          §7.12. Further Assurances. The Borrower and the Guarantor will cooperate with the Administrative Agent and execute such further instruments and documents as the Administrative Agent shall reasonably request to carry out to the Majority Banks’ satisfaction the transactions contemplated by this Agreement.

          §7.13. Notice of Potential Claims or Litigation. The Borrower shall deliver to the Banks written notice of the initiation of any action, claim, complaint, investigation or any other notice of dispute or litigation against the Borrower or any of its Subsidiaries that could reasonably be expected to have a Material Adverse Effect, or which questions the validity or enforceability of any Loan Document, together with a copy of each such complaint or other notice received by the Borrower or any of its Subsidiaries if requested by the Administrative Agent within 30 days of receipt thereof or of the determination that such action could reasonably be expected to have a Material Adverse Effect, whichever occurs later (and the Borrower will make such determination in each case as promptly as practicable).

     §7.14. Notice of Certain Events Concerning Environmental Claims. The Borrower will promptly, and in any event within ten (10) Business Days of the Borrower’s obtaining knowledge thereof, notify the Banks in writing of any of the following events:

any Subsidiary’s operations which violation could reasonably be expected to have a Material Adverse Effect;

          §7.15. Notice of Default. The Borrower will promptly notify the Banks in writing of the occurrence of any Default or Event of Default.

§8. NEGATIVE COVENANTS OF THE BORROWER. The Borrower agrees that, so long as any Obligation or Letter of Credit is outstanding or the Banks have any obligation to make Loans or any Issuing Bank has any obligation to issue, extend or renew any Letter of Credit hereunder, or the Banks have any obligation to reimburse any Issuing Bank for drawings honored under any Letter of Credit, it shall, and shall cause its Subsidiaries to, comply with the following covenants:

          §8.1. Restrictions on Indebtedness. The Borrower will not permit any of its Subsidiaries to create, incur, assume, or be or remain liable, contingently or otherwise, with respect to any Indebtedness, or become or be responsible in any manner (whether by agreement to purchase any obligations, stock, assets, goods or services, or to supply or advance any funds, assets, goods or services or otherwise) with respect to any Indebtedness of any other Person (other than the Borrower or any of its Subsidiaries), other than:

     (a) Indebtedness of the Borrower’s Subsidiaries listed in Schedule 8.1(a) and any extension, renewal or refinancing of such Indebtedness, provided that the terms and conditions of any such extensions, renewals or refinancings do not increase the relative priority of the original Indebtedness and provided, further, that such extended, renewed or refinanced Indebtedness does not in the aggregate exceed the Dollar amount of the original Indebtedness; and

     (b) Other Indebtedness of the Borrower’s Subsidiaries (other than of the Guarantor) provided that the aggregate amount of all such Indebtedness under this §8.1(b), when added (without duplication) to the aggregate outstanding amount of secured Indebtedness of the Borrower and its Subsidiaries under subsections (k), (l) and (m) of the definition of “Permitted Liens” and Indebtedness with respect to Permitted Receivables Transactions, shall not exceed 15% of Consolidated Tangible Assets at any time.

          §8.2. Restrictions on Liens. The Borrower will not, and will cause its Subsidiaries not to, create or incur or suffer to be created or incurred or to exist any Lien of any kind upon any property or assets of any character, whether now owned or hereafter acquired, or upon the income or profits therefrom; or transfer any of such property or assets or the income or profits therefrom for the purpose of subjecting the same to the payment of Indebtedness or performance of any other obligation in priority to payment of its general creditors; or acquire, or agree or have an option to acquire, any property or assets upon conditional sale or other title retention or purchase money security agreement, device or arrangement; or suffer to exist for a period of more than 30 days after the same shall have been incurred any Indebtedness or claim or demand against it which if unpaid might by law or upon bankruptcy or insolvency, or otherwise,

be given any priority whatsoever over its general creditors; or sell, assign, pledge or otherwise transfer any accounts, contract rights, general intangibles or chattel paper, with or without recourse, except for Permitted Liens.

     The Borrower and the Guarantor covenant and agree that if either of them or any of their Subsidiaries shall create or incur any Lien upon any of their respective properties or assets, whether now owned or hereafter acquired, other than Permitted Liens (unless prior written consent shall have been obtained from the Banks), the Borrower and the Guarantor will make or cause to be made effective provision whereby the Obligations and the Guaranteed Obligations will be secured by such Lien equally and ratably with any and all other Indebtedness thereby secured so long as such other Indebtedness shall be so secured; provided that the covenants of the Borrower and the Guarantor contained in this sentence shall only be in effect for so long as the Borrower or the Guarantor shall be similarly obligated under any other Indebtedness; provided, further, that an Event of Default shall occur for so long as such other Indebtedness becomes secured notwithstanding any actions taken by the Borrower or the Guarantor to ratably secure the Obligations and the Guaranteed Obligations hereunder.

          §8.3. Restrictions on Investments. Except to the extent provided in §8.4, neither the Borrower nor any Subsidiary may make or permit to exist or to remain outstanding any Investment, other than Investments in Cash Equivalents unless both before and after giving effect thereto (i) the Borrower and its Subsidiaries are in compliance with the covenants set forth in §§7, 8 and 9 hereof and (ii) there does not exist a Default or Event of Default and no Default or Event of Default would be created by the making of such Investment; provided that the aggregate amount of all Investments (excluding Investments in Cash Equivalents), does not exceed 15% of Consolidated Tangible Assets; and provided further that the ability of the Subsidiaries of the Borrower to incur any Indebtedness in connection with any Investment permitted by this §8.3 shall be governed by §8.1.

          §8.4. Mergers, Consolidations, Sales.

     (a) Neither the Borrower nor any Subsidiary shall be a party to any merger, consolidation or exchange of stock unless the Borrower shall be the surviving entity with respect to any such transaction to which the Borrower is a party and the Guarantor shall be the survivor of any merger with any other Subsidiary or a Subsidiary shall be the surviving entity (and continue to be a Subsidiary) with respect to any such transactions to which one or more Subsidiaries is a party (and the conditions set forth below are satisfied), or purchase or otherwise acquire all or substantially all of the assets or stock of any class of, or any partnership, membership or joint venture or other interest in, any other Person except as otherwise provided in §8.3 or this §8.4. Notwithstanding the foregoing, the Borrower and its Subsidiaries may purchase or otherwise acquire all or substantially all of the assets or stock of any class of, or joint venture or other interest in, any Person if the following conditions have been met: (i) the proposed transaction will not otherwise create a Default or an Event of Default hereunder; and (ii) the business to be acquired predominantly involves (A) the collection, transfer, hauling, disposal or recycling of solid waste or thermal soil remediation, or (B) other lines of businesses currently engaged in, or related, associated, complementary or supplementary thereto, whether from an operational, business, financial, technical or administrative standpoint;

provided that the Borrower or its Subsidiaries may purchase or otherwise acquire all or substantially all of the assets or stock of any class of, or any partnership, membership or joint venture or other interest in, any Persons in unrelated businesses, not to exceed a total aggregate amount of $400,000,000 during the term of this Agreement. Notwithstanding anything herein to the contrary, the ability of the Subsidiaries of the Borrower to incur any Indebtedness in connection with any transaction permitted pursuant to this §8.4 shall be governed by §8.1.

     (b) Neither the Borrower nor any Subsidiary shall sell, transfer, convey or lease any assets or group of assets, including the sale or transfer of any property owned by the Borrower or any Subsidiary in order then or thereafter to lease such property or lease other property which the Borrower or such Subsidiary intends to use for substantially the same purpose as the property being sold or transferred, or sell or assign, with or without recourse, any receivables, except (i) transfers of real or personal property among Subsidiaries of the Borrower, (ii) so long as no Default or Event of Default has occurred and is continuing, or would result therefrom, sales of assets or pursuant to a sale-leaseback transaction; provided that any net cash proceeds from any such sale or sale-leaseback shall, within 180 days, either be used to pay down outstanding Loans under this Agreement or be reinvested by such Person in assets of the business of the Borrower and its Subsidiaries, used for working capital, invested in Investments in accordance with the provisions of §8.3 or used for other general corporate purposes, (iii) sales of accounts receivable (and contract rights, general intangibles or chattel paper related thereto) more than sixty (60) days past due sold or assigned in the ordinary course of collecting past due accounts, or (iv) pursuant to a Permitted Receivables Transaction.

          §8.5. Restricted Distributions and Redemptions. Neither the Borrower nor any of its Subsidiaries will (a) declare or pay any Distributions, or (b) redeem, convert, retire or otherwise acquire shares of any class of its capital stock (other than in connection with a merger permitted by §8.4 hereof or conversion into another form of equity of any preferred shares of the Borrower existing as of the Effective Date pursuant to the terms thereof), unless at the time of such Distribution or redemption no Default or Event of Default exists or would be created hereunder. Notwithstanding the above, any Subsidiary may make Distributions to the Borrower and the Borrower agrees that neither the Borrower nor any Significant Subsidiary will enter into any agreement restricting Distributions from such Significant Subsidiary to the Borrower.

          §8.6. Employee Benefit Plans. None of the Borrower, any of its Subsidiaries, or any ERISA Affiliate will:

     (a) engage in any “prohibited transaction” within the meaning of §406 of ERISA or §4975 of the Code which could result in a material liability for the Borrower on a consolidated basis; or

     (b) permit any Guaranteed Pension Plan to incur an “accumulated funding deficiency”, as such term is defined in §302 of ERISA, whether or not such deficiency is or may be waived; or

     (c) fail to contribute to any Guaranteed Pension Plan to an extent which, or terminate any Guaranteed Pension Plan in a manner which, could result in the imposition of a lien or encumbrance on the assets of the Borrower or the Guarantor pursuant to §302(f) or §4068 of ERISA; or

     (d) permit or take any action which would result in the aggregate benefit liabilities (within the meaning of §4001 of ERISA), other than with respect to the Terminated Plans, of all Guaranteed Pension Plans exceeding the value of the aggregate assets of such Guaranteed Pension Plans, disregarding for this purpose the benefit liabilities and assets of any such Guaranteed Pension Plan with assets in excess of benefit liabilities.

     The Borrower and its Subsidiaries will (i) promptly upon the request of any Bank or the Administrative Agent, furnish to the Banks a copy of the most recent actuarial statement required to be submitted under §103(d) of ERISA and Annual Report, Form 5500, with all required attachments, in respect of each Guaranteed Pension Plan, and (ii) promptly upon receipt or dispatch, furnish to the Banks any notice, report or demand sent or received in respect of a Guaranteed Pension Plan under §§302, 4041, 4042, 4043, 4063, 4065, 4066 and 4068 of ERISA, or in respect of a Multiemployer Plan, under §§4041A, 4202, 4219, 4242 or 4245 of ERISA.

          §9.2. Total Debt to EBITDA. As of the end of any fiscal quarter of the Borrower, the Borrower will not permit the ratio of (a) Total Debt to (b) EBITDA for the four fiscal quarters then ending to exceed 3.50:1.00.

          §12.3. Remedies. In case any one or more of the Events of Default shall have occurred and be continuing, and whether or not the Banks shall have accelerated the maturity of the Loans and other Obligations pursuant to §12.1, each Bank, upon notice to the other Banks, if owed any amount with respect to the Loans or the Reimbursement Obligations, may proceed to protect and enforce its rights by suit in equity, action at law or other appropriate proceeding, whether for the specific performance of any covenant or agreement contained in this Agreement and the other Loan Documents or any instrument pursuant to which the Obligations to such Bank are evidenced, including, without limitation, as permitted by applicable law the obtaining of the ex parte appointment of a receiver, and, if such amount shall have become due, by declaration or otherwise, proceed to enforce the payment thereof or any legal or equitable right of such Bank, any recovery being subject to the terms of §29 hereof. No remedy herein conferred upon any Bank or the Administrative Agent or the holder of any Note is intended to be exclusive of any other remedy and each and every remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now or hereafter existing at law or in equity or by statute or any other provision of law.

§13. SETOFF. During the continuance of an Event of Default, any deposits or other sums credited by or due from any Bank to the Borrower and any securities or other property of the Borrower in the possession of such Bank may be applied to or set off against the payment of the

- 62 -

Obligations and any and all other liabilities, direct, or indirect, absolute or contingent, due or to become due, now existing or hereafter arising, of the Borrower to the Banks or the Administrative Agent. Any amounts set off with respect to the Obligations shall be distributed ratably in accordance with §29 among all of the Banks by the Bank setting off such amounts. If any Bank fails to share such setoff ratably, the Administrative Agent shall have the right to withhold such Bank’s share of the Borrower’s payments until each of the Banks shall have, in the aggregate, received a pro rata repayment.

§14. EXPENSES. Whether or not the transactions contemplated herein shall be consummated, the Borrower hereby promises to reimburse the Administrative Agent and the Lead Arrangers for all reasonable out-of-pocket fees and disbursements (including all reasonable attorneys’ fees) incurred or expended in connection with the syndication, preparation, filing or recording, or interpretation of this Agreement, the other Loan Documents, or any amendment, modification, approval, consent or waiver hereof or thereof. The Borrower further promises to reimburse the Administrative Agent and the Banks for all reasonable out-of-pocket fees and disbursements (including all reasonable legal fees and the allocable cost of in-house attorneys’ fees) incurred or expended in connection with the enforcement of any Obligations or the satisfaction of any indebtedness of the Borrower hereunder or under any other Loan Document, or in connection with any litigation, proceeding or dispute hereunder in any way related to the credit hereunder.

As to any matters not expressly provided for by this Agreement and the other Loan Documents, the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority Banks (or, when expressly required hereby, all of the Banks), and such instructions shall be binding upon all Banks; provided, however, that the Administrative Agent shall not be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement or the other Loan Documents or applicable law.

Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be liable to any of the Banks for any action taken or omitted to be taken by it or them under or in connection with this Agreement or the other Loan Documents, except for its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Administrative Agent: (i) may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable to the Banks for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (ii) makes no warranty or representation to any Bank and shall not be

          §15.3. Citibank and Affiliates. With respect to its Commitment, Citibank shall have the same rights and powers under this Agreement and under the other Loan Documents as any other Bank and may exercise the same as though it were not the Administrative Agent, and the term “Bank” or “Banks” shall, unless otherwise expressly indicated, include Citibank in its individual capacity. Citibank and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with, the Borrower, the Guarantor, any of their Subsidiaries and any Person who may do business with or own securities of the Borrower, the Guarantor, or any such Subsidiary, all as if Citibank were not the Administrative Agent and without any duty to account therefor to the Banks.

          §15.4. Bank Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Bank and based on the financial statements referred to in §6.4 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Bank and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents.

          §15.5. Indemnification. The Banks agree to indemnify the Administrative Agent (to the extent not reimbursed by the Borrower), ratably according to the respective amounts of their Commitments as most recently in effect at the time such indemnity is sought, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of this Agreement or the other Loan Documents or any action taken or omitted by the Administrative Agent under this Agreement or the other Loan Documents, provided that no Bank shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s gross negligence or willful misconduct. Without limiting the foregoing, each Bank agrees to reimburse the Administrative Agent promptly upon demand for its ratable share as

- 64 -

aforesaid of any out of pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement and the other Loan Documents, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrower.

          §15.6. Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Banks and the Borrower and may be removed at any time with or without cause by the Majority Banks. Upon any such resignation or removal, the Majority Banks shall have the right to appoint a successor Administrative Agent that, unless a Default or Event of Default shall have occurred and then be continuing, is reasonably acceptable to the Borrower. If no successor Administrative Agent shall have been so appointed by the Majority Banks, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation or the Majority Banks’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent, which shall be a commercial bank organized under the laws of the United States of America or of any State thereof and having total assets of at least $1,000,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent, the provisions of this §15 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement.

          §15.7. Lead Arrangers, Etc. The parties identified on the cover hereof as Lead Arrangers and Joint Bookrunners and Documentation Agents shall have no obligations or liabilities under this Agreement and the other Loan Documents.

          §15.8. Documents. The Administrative Agent will forward to each Bank, promptly after receipt thereof, a copy of each notice or other document furnished to the Administrative Agent for such Bank hereunder; provided, however, that, notwithstanding the foregoing, the Administrative Agent may furnish to the Banks a monthly summary with respect to Letters of Credit issued hereunder in lieu of copies of the related Letter of Credit Applications.

          §15.9. Action by the Banks, Consents, Amendments, Waivers, Etc. (a) No failure or delay by the Administrative Agent, any Issuing Bank or any Bank in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Banks and the Banks hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrower or the Guarantor therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this section, and then such

- 65 -

waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default or Event of Default, regardless of whether the Administrative Agent, any Bank or the Issuing Bank may have had notice or knowledge of such Default or Event of Default at the time.

          (b) Except as otherwise provided in §3.1(a) hereof with respect to Schedule 3.1, neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Majority Banks or by the Borrower and the Administrative Agent with the consent of the Majority Banks; provided that no such agreement shall (i) increase the Commitment of any Bank without the written consent of such Bank, (ii) reduce the principal amount of any Loan or Reimbursement Obligations, or reduce the rate of interest on the Loans or reduce any fees payable hereunder, without the written consent of each Bank affected thereby; (iii) postpone the date of any payment of the principal amount of any Loan, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Bank affected thereby; (iv) release the Borrower from its Obligations or the Guarantor from its Guaranteed Obligations hereunder without the written consent of each Bank; (v) modify §29(a) or any other provision of this Agreement providing for pro rata payments to or by the Banks; or (vi) change any of the provisions of this §15.9 or any provision of this Agreement requiring action by all the Banks, or the percentage of Banks constituting “Majority Banks”, without the written consent of each Bank; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent or any Issuing Bank hereunder without the prior written consent of the Administrative Agent or the Issuing Banks, as the case may be.

§16. INDEMNIFICATION. The Borrower agrees to indemnify and hold harmless the Banks, the Issuing Banks, the Lead Arrangers and the Administrative Agent and their affiliates, as well as their and their affiliates’ shareholders, directors, agents, officers, subsidiaries and affiliates, from and against all damages, losses, settlement payments, obligations, liabilities, claims, suits, penalties, assessments, citations, directives, demands, judgments, actions or causes of action, whether statutorily created or under the common law, and reasonable costs and expenses incurred, suffered, sustained or required to be paid by an indemnified party by reason of or resulting from the transactions contemplated hereby, except any of the foregoing which result from the gross negligence or willful misconduct of such indemnified party as determined by a court of competent jurisdiction. In any investigation, enforcement matter, proceeding or litigation, or the preparation therefor, the Banks, the Issuing Banks, the Lead Arrangers and the Administrative Agent shall be entitled to select their own counsel and, in addition to the foregoing indemnity, the Borrower agrees to pay promptly the reasonable fees and expenses of such counsel (including the non-duplicative allocated cost of internal counsel), and settlement costs. In the event of the commencement of any such proceeding or litigation against the Banks or Administrative Agent by third parties, the Borrower shall be entitled to participate in such proceeding or litigation with counsel of their choice at their expense. The covenants of this §16 shall survive payment or satisfaction of payment of amounts owing with respect to any Note or the Loans and satisfaction of all the Obligations hereunder and under the Loan Documents, IT BEING THE INTENT OF THE PARTIES HERETO THAT

ALL SUCH INDEMNIFIED PARTIES SHALL BE INDEMNIFIED FOR THEIR ORDINARY SOLE OR CONTRIBUTORY NEGLIGENCE. NO PARTY SHALL BE LIABLE TO ANY OTHER PARTY IN RESPECT OF ANY INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES.

§17. WITHHOLDING TAXES. The Borrower hereby agrees that:

     (a) Any and all payments made by the Borrower hereunder shall be made free and clear of, and without deduction for, any and all present or future taxes, levies, fees, duties, imposts, deductions, charges or withholdings of any nature whatsoever, excluding, in the case of each of the Administrative Agent and each of the Banks (including, without limitation, the Issuing Banks), (i) taxes imposed on, or measured by, its net income or profits, (ii) franchise taxes imposed on it, (iii) taxes imposed by any jurisdiction as a direct consequence of it, or any of its affiliates, having a present or former connection with such jurisdiction, including, without limitation, being organized, existing or qualified to do business, doing business or maintaining a permanent establishment or office in such jurisdiction, and (iv) taxes imposed by reason of its failure to comply with any applicable certification, identification, information, documentation or other reporting requirement (all such non-excluded taxes being hereinafter referred to as “Indemnifiable Taxes”). In the event that any withholding or deduction from any payment to be made by the Borrower hereunder is required in respect of any Indemnifiable Taxes pursuant to any applicable law, or governmental rule or regulation, then the Borrower will (i) direct to the relevant taxing authority the full amount required to be so withheld or deducted, (ii) forward to the Administrative Agent for delivery to the applicable Bank an official receipt or other documentation satisfactory to the Administrative Agent and the applicable Bank evidencing such payment to such taxing authority, and (iii) direct to the Administrative Agent for the account of the relevant Banks such additional amount or amounts as is necessary to ensure that the net amount actually received by each relevant Bank will equal the full amount such Bank would have received had no such withholding or deduction (including any Indemnifiable Taxes on such additional amounts) been required. Moreover, if any Indemnifiable Taxes are directly asserted against the Administrative Agent or any Bank with respect to any payment received by the Administrative Agent or such Bank by reason of the Borrower’s failure to properly deduct and withhold such Indemnifiable Taxes from such payment, the Administrative Agent or such Bank may pay such Indemnifiable Taxes and the Borrower will promptly pay all such additional amounts (including any penalties, interest or reasonable expenses) as is necessary in order that the net amount received by such Person after the payment of such Indemnifiable Taxes (including any Indemnifiable Taxes on such additional amount) shall equal the amount such Person would have received had not such Indemnifiable Taxes been asserted; provided that the Administrative Agent or such Bank, as the case may be, agrees to use commercially reasonable efforts, at the expense of the Borrower, to contest or otherwise challenge such Indemnifiable Taxes if the Administrative Agent or such Bank, as applicable, determines in good faith that a reasonable basis exists to do so. Any such payment shall be made promptly after the receipt by the Borrower from the Administrative Agent or such Bank, as the case may be, of a written statement setting forth in reasonable detail the amount of the Indemnifiable Taxes and the basis of the claim.

     (b) The Borrower shall pay any present or future stamp or documentary taxes or any other excise or any other similar levies which arise from any payment made hereunder or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or any other Loan Document (“Other Taxes”).

     (c) The Borrower hereby indemnifies and holds harmless the Administrative Agent and each Bank for the full amount of Indemnifiable Taxes or Other Taxes (including, without limitation, any Indemnifiable Taxes or Other Taxes imposed on amounts payable under this §17) paid by the Administrative Agent or such Bank, as the case may be, and any liability (including penalties, interest and reasonable expenses) arising therefrom or with respect thereto, by reason of the Borrower’s failure to properly deduct and withhold Indemnifiable Taxes pursuant to paragraph (a) above or to properly pay Other Taxes pursuant to paragraph (b) above. Any indemnification payment from the Borrower under the preceding sentence shall be made promptly after receipt by the Borrower from the Administrative Agent or Bank of a written statement setting forth in reasonable detail the amount of such Indemnifiable Taxes or such Other Taxes, as the case may be, and the basis of the claim.

     (d) If the Borrower pays any amount under this §17 to the Administrative Agent or any Bank and such payee knowingly receives a refund or tax credit in respect of any taxes with respect to which such amount was paid, the Administrative Agent or such Bank, as the case may be, shall remit to the Borrower, promptly following the receipt thereof by such payee, an amount equal to the amount determined by such payee to be equal to the amount of any net reduction in taxes actually obtained by such payee and determined by it to be allocable to such refund or credit; provided, that the decision as to whether or not to claim any such refund or credit, and as to the amount and allocation of any such refund or credit so claimed, shall be made by each such payee in its sole and absolute discretion; and provided, further, that nothing herein shall be deemed to obligate any Bank or the Administrative Agent to disclose to the Borrower or the Guarantor its tax returns or any information regarding its tax affairs.

     (e) In the event any taxing authority notifies the Borrower or the Guarantor that any of them has improperly failed to deduct or withhold any taxes (other than Indemnifiable Taxes) from a payment made hereunder to the Administrative Agent or any Bank, the Borrower shall timely and fully pay such taxes to such taxing authority.

     (f) The Administrative Agent or the Banks shall, upon the request of the Borrower, take reasonable measures to avoid or mitigate the amount of Indemnifiable Taxes required to be deducted or withheld from any payment made hereunder if such measures can be taken without such Person in its sole judgment suffering any legal, regulatory or economic disadvantage.

     (g) Without prejudice to the survival of any other agreement of the parties hereunder, the agreements and obligations of the Borrower contained in this §17 shall survive the payment in full of the Obligations.

§18. TREATMENT OF CERTAIN CONFIDENTIAL INFORMATION.

          §18.1. Confidentiality. Each of the Banks and the Administrative Agent agrees, on behalf of itself and each of its affiliates, directors, officers, employees and representatives, to use reasonable precautions to keep confidential, in accordance with their customary procedures for handling confidential information of the same nature and in accordance with safe and sound banking practices, any non-public information supplied to it by the Borrower or any of its Subsidiaries pursuant to this Agreement that is identified by such Person as being confidential at the time the same is delivered to the Banks or the Administrative Agent, provided that nothing herein shall limit the disclosure of any such information (a) after such information shall have become public other than through a violation of this §18, or becomes available to any of the Banks or the Administrative Agent on a nonconfidential basis from a source other than the Borrower, (b) to the extent required by statute, rule, regulation or judicial process, (c) to counsel for any of the Banks or the Administrative Agent, (d) to bank examiners or any other regulatory authority having jurisdiction over any Bank or any of its affiliates or the Administrative Agent, or to auditors or accountants, (e) to the Administrative Agent, any Bank or any Financial Affiliate, (f) in connection with any litigation to which any one or more of the Banks, the Administrative Agent or any Financial Affiliate is a party, or in connection with the enforcement of rights or remedies hereunder or under any other Loan Document, (g) to an affiliate of any Bank or the Administrative Agent, (h) to any actual or prospective assignee or participant or any actual or prospective counterparty (or its advisors) to any swap or derivative transactions referenced to credit or other risks or events arising under this Agreement or any other Loan Document so long as such assignee, participant or counterparty, as the case may be, agrees to be bound by the provisions of §18.1, or (i) with the consent of the Borrower.

          §18.2. Prior Notification. Unless specifically prohibited by applicable law or court order, each of the Banks and the Administrative Agent shall, prior to disclosure thereof, notify the Borrower of any request for disclosure of any such non-public information by any governmental agency or representative thereof (other than any such request in connection with an examination of the financial condition of such Bank by such governmental agency) or pursuant to legal process.

          §18.3. Other. In no event shall any Bank or the Administrative Agent be obligated or required to return any materials furnished to it or any Financial Affiliate by the Borrower or any of its Subsidiaries. The obligations of each Bank under this §18 shall supersede and replace the obligations of such Bank under any confidentiality letter in respect of this financing signed and delivered by such Bank to the Borrower prior to the date hereof and shall be binding upon any assignee of, or purchaser of any participation in, any interest in any of the Loans or Reimbursement Obligations from any Bank.

§19. SURVIVAL OF COVENANTS, ETC. Unless otherwise stated herein, all covenants, agreements, representations and warranties made herein, in the other Loan Documents or in any documents or other papers delivered by or on behalf of the Borrower or the Guarantor pursuant hereto shall be deemed to have been relied upon by the Banks, the Issuing Banks and the Administrative Agent, notwithstanding any investigation heretofore or hereafter made by them, and shall survive the making by the Banks of the Loans and the issuance, extension or renewal of any Letters of Credit by any Issuing Bank, as herein contemplated, and shall continue in full force and effect so long as any amount due under this Agreement, any Obligation, or any Letter

of Credit remains outstanding and unpaid or any Bank has any obligation to make any Loans or any Issuing Bank has any obligation to issue, extend, or renew any Letters of Credit hereunder. All statements contained in any certificate or other paper delivered by or on behalf of the Borrower pursuant hereto or in connection with the transactions contemplated hereby shall constitute representations and warranties by the Borrower hereunder.

§20. ASSIGNMENT AND PARTICIPATION. It is understood and agreed that each Bank shall have the right to assign at any time all or a portion of its Commitment Percentage and interests in the risk relating to the Loans, outstanding Letters of Credit and its Commitment hereunder in an amount equal to or greater than $5,000,000 (or, if a Bank’s Commitment is less than $5,000,000, in a minimum amount equal to such Bank’s Commitment; provided that prior to any Commitment reductions pursuant to §2.3.1, such Bank’s Commitment was at least $5,000,000) to additional banks, other financial institutions or Bank Affiliates with the prior written approval of the Administrative Agent and each Issuing Bank and, so long as no Event of Default has occurred and is continuing, the consent of the Borrower (provided that the Borrower’s consent shall not be required in the case of an assignment to a Bank Affiliate or to an Approved Fund), which approvals shall not be unreasonably withheld. Any Bank may at any time, and from time to time, assign to any branch, lending office, or Bank Affiliate all or any part of its rights and obligations under the Loan Documents by notice to the Administrative Agent and the Borrower. It is further agreed that each bank or other financial institution which executes and delivers to the Administrative Agent and the Borrower hereunder an Assignment and Acceptance substantially in the form of Exhibit D hereto (an “Assignment and Acceptance”) together with an assignment fee in the amount of $3,500 payable by the assigning Bank to the Administrative Agent, shall, on the date specified in such Assignment and Acceptance, become a party to this Agreement and the other Loan Documents for all purposes of this Agreement and the other Loan Documents, and its portion of the Commitment, the Loans and Letters of Credit shall be as set forth in such Assignment and Acceptance. The Bank assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights (except for indemnity rights arising out of the period prior to such assignment) and be released from its obligations under this Agreement and the other Loan Documents. Upon the execution and delivery of such Assignment and Acceptance (a) to the extent applicable, the Borrower shall issue Notes (and replacement Notes) or the Administrative Agent shall make appropriate entries on the applicable loan account(s) to reflect such assignment of Loan(s); and (b) this Agreement and Schedule 1 shall be deemed to be appropriately amended to reflect (i) the status of the bank, financial institution or Bank Affiliate as a party hereto and (ii) the status and rights of the Banks hereunder.

     Each Bank shall also have the right to grant participations to one or more banks, other financial institutions or Bank Affiliates in its Commitment, the Loans and outstanding Letters of Credit. The documents evidencing any such participation shall limit such participating bank’s, financial institution’s or Bank Affiliate’s, voting rights with respect to this Agreement to the matters set forth in §15.9(b)(i) – (v); and each such participant shall be entitled to the benefit of §5.5 hereof to the extent of its participation, subject to the limitations set forth therein.

     Notwithstanding the foregoing, no assignment or participation shall operate to increase the Total Commitment hereunder or otherwise alter the substantive terms of this Agreement, and no Bank which retains a Commitment hereunder shall have a Commitment of less than

$5,000,000, except as a result of reductions in the Total Commitment pursuant to §2.3 hereof.

     Anything contained in this §20 to the contrary notwithstanding, any Bank may at any time pledge all or any portion of its interest and rights under this Agreement (including all or any portion of its Notes) to any of the twelve Federal Reserve Banks organized under §4 of the Federal Reserve Act, 12 U.S.C. §341. No such pledge or the enforcement thereof shall release the pledgor Bank from its obligations hereunder or under any of the other Loan Documents.

     The Borrower agrees that in addition to disclosures made in accordance with standard and customary banking practices any Bank may disclose information obtained by such Bank pursuant to this Agreement to assignees or participants and potential assignees or participants hereunder; provided that such assignees or participants or potential assignees or participants shall agree to be bound by §18 hereof.

§21. PARTIES IN INTEREST. All the terms of this Agreement and the other Loan Documents shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto and thereto; provided, that neither the Borrower nor the Guarantor shall assign or transfer its rights or obligations hereunder or thereunder without the prior written consent of each of the Banks.

§22. NOTICES, ETC. (a) Subject to clauses (b) and (c) of this §22, all notices and other communications made or required to be given pursuant to this Agreement or the other Loan Documents shall be in writing and shall be delivered in hand, mailed by registered or certified United States first class mail, postage prepaid, or sent by telegraph, telex or facsimile and confirmed by letter, addressed as follows:

     Any such notice or demand shall be deemed to have been duly given or made and to have become effective (a) if delivered by hand to a responsible officer of the party to which it is directed, at the time of the receipt thereof by such officer, (b) if sent by registered or certified first-class mail, postage prepaid, seven Business Days after the posting thereof, and (c) if sent by telex, facsimile, or cable, at the time of the dispatch thereof, if in normal business hours in the country of receipt, or otherwise at the opening of business on the following Business Day.

          (b) The Borrower hereby agrees that it will provide to the Administrative Agent all information, documents and other materials that it is obligated to furnish to the Administrative Agent pursuant to this Agreement and the other Loan Documents, including,

without limitation, all notices, requests, financial statements, financial and other reports, certificates and other information materials, but excluding any such communication that (i) relates to a request for a new, or a conversion of an existing, Borrowing or other extension of credit (including any election of an interest rate or Interest Period relating thereto), (ii) relates to the payment of any principal or other amount due under this Agreement prior to the scheduled date therefor, (iii) provides notice of any Default or Event of Default under this Agreement or (iv) is required to be delivered to satisfy any condition precedent to the effectiveness of this Agreement and/or any borrowing or other extension of credit thereunder (all such non-excluded communications being referred to herein collectively as “Communications”), by transmitting the Communications in an electronic/soft medium in a format acceptable to the Administrative Agent to ***@***. In addition, the Borrower agrees to continue to provide the Communications to the Administrative Agent in the manner specified in this Agreement but only to the extent requested by the Administrative Agent.

          (c) The Borrower further agrees that the Administrative Agent may make the Communications available to the Banks by posting the Communications on Intralinks or a substantially similar electronic transmission system (the “Platform”).

          (d) THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE”. THE AGENT PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS, OR THE ADEQUACY OF THE PLATFORM AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS OR OMISSIONS IN THE COMMUNICATIONS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, AN WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT PARTIES IN CONNECTION WITH THE COMMUNICATIONS OR THE PLATFORM. IN NO EVENT SHALL THE ADMINISTRATIVE AGENT OR ANY OF ITS AFFILIATES OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR REPRESENTATIVES (COLLECTIVELY, “AGENT PARTIES”) HAVE ANY LIABILITY TO THE BORROWER, ANY BANK OR ANY OTHER PERSON OR ENTITY FOR DAMAGES OF ANY KIND, INCLUDING, WITHOUT LIMITATION, DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT, CONTRACT OR OTHERWISE) ARISING OUT OF THE BORROWER’S OR THE ADMINISTRATIVE AGENT’S TRANSMISSION OF COMMUNICATIONS THROUGH THE INTERNET, EXCEPT TO THE EXTENT THE LIABILITY OF ANY AGENT PARTY IS FOUND IN A FINAL NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED PRIMARILY FROM SUCH AGENT PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

          (e) The Administrative Agent agrees that the receipt of the Communications by the Administrative Agent at its e-mail address set forth above shall constitute effective delivery of the Communications to the Administrative Agent for purposes of this Agreement. Each Bank agrees that notice to it (as provided in the next sentence) specifying that the Communications have been posted to the Platform shall constitute effective delivery of the

Communications to such Bank for purposes of this Agreement. Each Bank agrees to notify the Administrative Agent in writing (including by electronic communication) from time to time of such Bank’s e-mail address to which the foregoing notice may be sent by electronic transmission and (ii) that the foregoing notice may be sent to such e-mail address.

          (f) Nothing herein shall prejudice the right of the Administrative Agent or any Bank to give any notice or other communication pursuant to this Agreement in any other manner specified herein.

§23. MISCELLANEOUS. The rights and remedies herein expressed are cumulative and not exclusive of any other rights which the Banks, the Issuing Banks or the Administrative Agent would otherwise have. The captions in this Agreement are for convenience of reference only and shall not define or limit the provisions hereof. This Agreement and any amendment hereof may be executed in several counterparts and by each party on a separate counterpart, each of which when so executed and delivered shall be an original, but all of which together shall constitute one instrument. In proving this Agreement it shall not be necessary to produce or account for more than one such counterpart signed by the party against whom enforcement is sought. This Agreement, to the extent signed and delivered by means of a facsimile machine, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto, each other party hereto shall re-execute original forms thereof and deliver them to all other parties. No party hereto shall raise the use of a facsimile machine to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine as a defense to the formation of a contract and each party forever waives such defense.

§24. CONSENTS, ETC. Neither this Agreement nor any term hereof may be changed, waived, discharged or terminated, except as provided in this §24, subject to the provisions of §15.9. No waiver shall extend to or affect any obligation not expressly waived or impair any right consequent thereon. Except as otherwise expressly provided in this Agreement, any consent or approval required or permitted by this Agreement to be given by the Banks may be given, and any term of this Agreement or of any other instrument related hereto or mentioned herein may be amended, and the performance or observance by the Borrower or the Guarantor of any terms of this Agreement or such other instrument or the continuance of any Default or Event of Default may be waived (either generally or in a particular instance and either retroactively or prospectively) with, but only with, the written consent of the Borrower and the Majority Banks. To the extent permitted by law, no course of dealing or delay or omission on the part of any of the Banks, the Issuing Banks or the Administrative Agent in exercising any right shall operate as a waiver thereof or otherwise be prejudicial thereto. No notice to or demand upon the Borrower or the Guarantor shall entitle the Borrower to other or further notice or demand in similar or other circumstances.

OBLIGATIONS HEREUNDER OR THEREUNDER OR THE PERFORMANCE OF SUCH RIGHTS AND OBLIGATIONS. EXCEPT AS PROHIBITED BY LAW, THE BORROWER AND THE GUARANTOR HEREBY WAIVE ANY RIGHT EITHER OF THEM MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION REFERRED TO IN THE PRECEDING SENTENCE ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES. THE BORROWER AND THE GUARANTOR EACH (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY BANK, ANY ISSUING BANK, THE ADMINISTRATIVE AGENT OR ANY AGENT HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH BANK, SUCH ISSUING BANK, THE ADMINISTRATIVE AGENT OR SUCH AGENT WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS AND (B) ACKNOWLEDGES THAT THE ADMINISTRATIVE AGENT, THE BANKS, AND THE ISSUING BANKS HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BECAUSE OF, AMONG OTHER THINGS, THE BORROWER’S AND THE GUARANTOR’S WAIVERS AND CERTIFICATIONS CONTAINED HEREIN.

§26. GOVERNING LAW; SUBMISSION TO JURISDICTION. THIS AGREEMENT AND EACH OF THE OTHER LOAN DOCUMENTS ARE CONTRACTS UNDER THE LAWS OF THE STATE OF NEW YORK AND SHALL, PURSUANT TO NEW YORK GENERAL OBLIGATIONS LAW §5-1401, BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF NEW YORK. THE BORROWER AND THE GUARANTOR CONSENT AND AGREE THAT ANY SUIT FOR THE ENFORCEMENT OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR ANY FEDERAL COURT SITTING THEREIN AND CONSENTS TO THE NONEXCLUSIVE JURISDICTION OF SUCH COURT AND SERVICE OF PROCESS IN ANY SUCH SUIT BEING MADE UPON THE BORROWER IN ACCORDANCE WITH LAW AT THE ADDRESS SPECIFIED IN §22. THE BORROWER AND THE GUARANTOR HEREBY WAIVE ANY OBJECTION THAT THEY MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH SUIT OR ANY SUCH COURT OR THAT SUCH SUIT IS BROUGHT IN AN INCONVENIENT FORUM.

§27. SEVERABILITY. The provisions of this Agreement are severable and if any one clause or provision hereof shall be held invalid or unenforceable in whole or in part in any jurisdiction, then such invalidity or unenforceability shall affect only such clause or provision, or part thereof, in such jurisdiction, and shall not in any manner affect such clause or provision in any other jurisdiction, or any other clause or provision of this Agreement in any jurisdiction.

§28. GUARANTY.

          §28.1. Guaranty. For value received and hereby acknowledged and as an inducement to the Banks and the Issuing Banks to make the Loans available to the Borrower, and issue, extend or renew Letters of Credit for the account of the Borrower, the Guarantor hereby unconditionally and irrevocably guarantees (a) the full punctual payment when due, whether at stated maturity, by acceleration or otherwise, of all Obligations of the Borrower now or hereafter

existing whether for principal, interest, fees, expenses or otherwise, and (b) the strict performance and observance by the Borrower of all agreements, warranties and covenants applicable to the Borrower in the Loan Documents and (c) the obligations of the Borrower under the Loan Documents (such Obligations collectively being hereafter referred to as the “Guaranteed Obligations”).

          §28.2. Guaranty Absolute. The Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms hereof, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Bank, any Issuing Bank or the Administrative Agent with respect thereto. The liability of the Guarantor under the guaranty granted under this Agreement with regard to the Guaranteed Obligations shall be absolute and unconditional irrespective of:

     (a) any change in the time, manner or place of payment of, or in any other term of, all or any of the Guaranteed Obligations or any other amendment or waiver of or any consent to departure from this Agreement or any other Loan Document (with regard to such Guaranteed Obligations);

     (b) any release or amendment or waiver of or consent to departure from any other guaranty for all or any of its Guaranteed Obligations;

     (c) any change in ownership of the Borrower;

     (d) any acceptance of any partial payment(s) from the Borrower or the Guarantor; or

     (e) any other circumstance whatsoever which might otherwise constitute a defense available to, or a discharge of, a guarantor or surety or the Borrower in respect of its Obligations under any Loan Document.

     The guaranty under this Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any Guaranteed Obligation is rescinded or must otherwise be returned by the Banks, the Issuing Banks or the Administrative Agent upon the insolvency, bankruptcy or reorganization of the Borrower or otherwise, all as though such payment had not been made.

          §28.3. Effectiveness; Enforcement. The guaranty under this Agreement shall be effective and shall be deemed to be made with respect to each Loan and each Letter of Credit as of the time it is made, issued or extended, or becomes a Letter of Credit under this Agreement, as applicable. No invalidity, irregularity or unenforceability by reason of any bankruptcy or similar law, or any law or order of any government or agency thereof purporting to reduce, amend or otherwise affect any liability of the Borrower, and no defect in or insufficiency or want of powers of the Borrower or irregular or improperly recorded exercise thereof, shall impair, affect, be a defense to or claim against such guaranty. The guaranty under this Agreement is a continuing guaranty and shall (a) survive any termination of this Agreement, and (b) remain in full force and effect until payment in full of, and performance of, all Guaranteed Obligations and all other amounts payable under this Agreement. The guaranty under this Agreement is made for the benefit of the Administrative Agent, the Issuing Banks and the Banks and their successors

and assigns, and may be enforced from time to time as often as occasion therefor may arise and without requirement on the part of the Administrative Agent, the Issuing Banks or the Banks first to exercise any rights against the Borrower, or to resort to any other source or means of obtaining payment of any of the said obligations or to elect any other remedy.

          §28.4. Waiver. Except as otherwise specifically provided in any of the Loan Documents, the Guarantor hereby waives promptness, diligence, protest, notice of protest, all suretyship defenses, notice of acceptance and any other notice with respect to any of its Guaranteed Obligations and the guaranty under this Agreement and any requirement that the Banks, the Issuing Banks or the Administrative Agent protect, secure, perfect any security interest or Lien or any property subject thereto or exhaust any right or take any action against the Borrower or any other Person. The Guarantor also irrevocably waives, to the fullest extent permitted by law, all defenses which at any time may be available to it in respect of its Guaranteed Obligations by virtue of any statute of limitations, valuation, stay, moratorium law or other similar law now or hereafter in effect.

          §28.5. Expenses. The Guarantor hereby promises to reimburse (a) the Administrative Agent for all reasonable out-of-pocket fees and disbursements (including all reasonable attorneys’ fees), incurred or expended in connection with the preparation, filing or recording, or interpretation of the guaranty under this Agreement, the other Loan Documents or any amendment, modification, approval, consent or waiver hereof or thereof, and (b) the Administrative Agent, the Issuing Banks and the Banks and their respective affiliates for all reasonable out-of-pocket fees and disbursements (including reasonable attorneys’ fees), incurred or expended in connection with the enforcement of its Guaranteed Obligations (whether or not legal proceedings are instituted). The Guarantor will pay any taxes (including any interest and penalties in respect thereof) other than the Banks’ taxes based on overall income or profits, payable on or with respect to the transactions contemplated by the guaranty under this Agreement, the Guarantor hereby agreeing jointly and severally to indemnify each Bank with respect thereto.

          §28.6. Concerning Joint and Several Liability of the Guarantor.

     (a) The Guarantor hereby irrevocably and unconditionally accepts, not merely as a surety but also as a co-debtor, joint and several liability with the Borrower, with respect to the payment and performance of all of its Guaranteed Obligations (including, without limitation, any Guaranteed Obligations arising under this §28), it being the intention of the parties hereto that all such Guaranteed Obligations shall be the joint and several Guaranteed Obligations of the Guarantor and the Borrower without preferences or distinction among them.

     (b) If and to the extent that the Borrower shall fail to make any payment with respect to any of its Obligations as and when due or to perform any of its Guaranteed Obligations in accordance with the terms thereof, then in each such event the Guarantor will make such payment with respect to, or perform, such Guaranteed Obligation.

     (c) The Guaranteed Obligations of the Guarantor under the provisions of this §28 constitute full recourse obligations of the Guarantor enforceable against the

Guarantor to the full extent of its properties and assets, irrespective of the validity, regularity or enforceability of this Agreement or any other circumstance whatsoever.

     (d) Except as otherwise expressly provided in this Agreement, the Guarantor hereby waives notice of acceptance of its joint and several liability, notice of any Loans made, or Letters of Credit issued under this Agreement, notice of any action at any time taken or omitted by the Administrative Agent, the Issuing Banks or the Banks under or in respect of any of the Guaranteed Obligations, and, generally, to the extent permitted by applicable law, all demands, notices and other formalities of every kind in connection with this Agreement. The Guarantor hereby assents to, and waives notice of, any extension or postponement of the time for the payment of any of the Guaranteed Obligations, the acceptance of any payment of any of the Guaranteed Obligations, the acceptance of any partial payment thereon, any waiver, consent or other action or acquiescence by the Administrative Agent, the Issuing Banks or the Banks at any time or times in respect of any Default or Event of Default by the Borrower or the Guarantor in the performance or satisfaction of any term, covenant, condition or provision of this Agreement or any other Loan Document, any and all other indulgences whatsoever by the Administrative Agent, the Issuing Banks or the Banks in respect of any of the Guaranteed Obligations, and the taking, addition, substitution or release, in whole or in part, at any time or times, of any security for any of the Guaranteed Obligations or the addition, substitution or release, in whole or in part, of the Borrower or the Guarantor. Without limiting the generality of the foregoing, the Guarantor assents to any other action or delay in acting or failure to act on the part of the Banks, the Issuing Banks or the Administrative Agent with respect to the failure by the Borrower or the Guarantor to comply with its respective Obligations or Guaranteed Obligations, including, without limitation, any failure strictly or diligently to assert any right or to pursue any remedy or to comply fully with applicable laws or regulations thereunder, which might, but for the provisions of this §28, afford grounds for terminating, discharging or relieving the Guarantor, in whole or in part, from any of the Guaranteed Obligations under this §28, it being the intention of the Guarantor that, so long as any of the Guaranteed Obligations hereunder remain unsatisfied, the Guaranteed Obligations of the Guarantor under this §28 shall not be discharged except by performance and then only to the extent of such performance. The Guaranteed Obligations of the Guarantor under this §28 shall not be diminished or rendered unenforceable by any winding up, reorganization, arrangement, liquidation, reconstruction or similar proceeding with respect to the Borrower or the Guarantor or the Banks, the Issuing Banks or the Administrative Agent. The joint and several liability of the Guarantor hereunder shall continue in full force and effect notwithstanding any absorption, merger, consolidation, amalgamation or any other change whatsoever in the name, membership, constitution or place of formation of the Borrower or the Guarantor, the Banks, the Issuing Banks or the Administrative Agent.

     (e) The Guarantor shall be liable under this §28 only for the maximum amount of such liabilities that can be incurred under applicable law without rendering this §28 voidable under applicable law relating to fraudulent conveyance and fraudulent transfer, and not for any greater amount. Accordingly, if any obligation under any provision under this §28 shall be declared to be invalid or unenforceable in any respect or to any extent, it is the stated intention and agreement of the Guarantor, the Administrative

Agent, the Issuing Banks and the Banks that any balance of the obligation created by such provision and all other obligations of the Guarantor under this §28 to the Banks, the Issuing Banks or the Administrative Agent shall remain valid and enforceable, and that all sums not in excess of those permitted under applicable law shall remain fully collectible by the Banks, the Issuing Banks and the Administrative Agent from the Borrower or the Guarantor, as the case may be.

     (f) The provisions of this §28 are made for the benefit of the Administrative Agent, the Issuing Banks and the Banks and their successors and assigns, and may be enforced in good faith by them from time to time against the Guarantor as often as occasion therefor may arise and without requirement on the part of the Administrative Agent, the Issuing Banks or the Banks first to marshal any of their claims or to exercise any of their rights against the Borrower or the Guarantor or to exhaust any remedies available to them against the Borrower or the Guarantor or to resort to any other source or means of obtaining payment of any of the obligations hereunder or to elect any other remedy. The provisions of this §28 shall remain in effect until all of the Guaranteed Obligations shall have been paid in full or otherwise fully satisfied and the Commitments have expired and all outstanding Letters of Credit have expired, matured or otherwise been terminated. If at any time, any payment, or any part thereof, made in respect of any of the Guaranteed Obligations, is rescinded or must otherwise be restored or returned by the Banks, the Issuing Banks or the Administrative Agent upon the insolvency, bankruptcy or reorganization of the Borrower or the Guarantor, or otherwise, the provisions of this §28 will forthwith be reinstated in effect, as though such payment had not been made.

          §28.7. Waiver. Until the final payment and performance in full of all of the Obligations, the Guarantor shall not exercise and the Guarantor hereby waives any rights the Guarantor may have against the Borrower arising as a result of payment by the Guarantor hereunder, by way of subrogation, reimbursement, restitution, contribution or otherwise, and will not prove any claim in competition with the Administrative Agent, the Issuing Banks or any Bank in respect of any payment hereunder in any bankruptcy, insolvency or reorganization case or proceedings of any nature; the Guarantor will not claim any setoff, recoupment or counterclaim against the Borrower in respect of any liability of the Borrower to the Guarantor; and the Guarantor waives any benefit of and any right to participate in any collateral security which may be held by the Administrative Agent, the Issuing Banks or any Bank.

          §28.8. Subrogation; Subordination. The payment of any amounts due with respect to any indebtedness of the Borrower for money borrowed or credit received now or hereafter owed to the Guarantor is hereby subordinated to the prior payment in full of all of the Obligations. The Guarantor agrees that, after the occurrence of any default in the payment or performance of any of the Obligations, the Guarantor will not demand, sue for or otherwise attempt to collect any such indebtedness of the Borrower to the Guarantor until all of the Obligations shall have been paid in full. If, notwithstanding the foregoing sentence, the Guarantor shall collect, enforce or receive any amounts in respect of such indebtedness while any Obligations are still outstanding, such amounts shall be collected, enforced and received by the Guarantor as trustee for the Banks, the Issuing Banks and the Administrative Agent and be paid over to the Administrative Agent at Default, for the benefit of the Banks, the Issuing

Banks, and the Administrative Agent on account of the Obligations without affecting in any manner the liability of the Guarantor under the other provisions hereof.

§29. PRO RATA TREATMENT.

          (a) Notwithstanding anything to the contrary set forth herein, each payment or prepayment of principal and interest received after the occurrence of an Event of Default hereunder shall be distributed pro rata among the Banks, in accordance with the aggregate outstanding principal amount of the Obligations owing to each Bank divided by the aggregate outstanding principal amount of all Obligations.

          (b) Each Bank agrees that if it shall, through the exercise of a right of banker’s lien, setoff or counterclaim against any Borrower (pursuant to §13 or otherwise), including a secured claim under Section 506 of the Bankruptcy Code or other security or interest arising from or in lieu of, such secured claim, received by such Bank under any applicable bankruptcy, insolvency or other similar law or otherwise, obtain payment (voluntary or involuntary) in respect of the Notes, Loans, Reimbursement Obligations and other Obligations held by it (other than pursuant to §5.5, §5.6 or §5.8) as a result of which the unpaid principal portion of the Notes and the Obligations held by it shall be proportionately less than the unpaid principal portion of the Notes and the Obligations held by any other Bank, it shall be deemed to have simultaneously purchased from such other Bank a participation in the Notes and the Obligations held by such other Bank, so that the aggregate unpaid principal amount of the Notes and the Obligations and participations in Notes and Obligations held by each Bank shall be in the same proportion to the aggregate unpaid principal amount of the Notes and the Obligations then outstanding as the principal amount of the Notes and the Obligations held by it prior to such exercise of banker’s lien, setoff or counterclaim was to the principal amount of all Notes and Obligations outstanding prior to such exercise of banker’s lien, setoff or counterclaim; provided, however, that if any such purchase or purchases or adjustments shall be made pursuant to this §29 and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustments restored without interest. The Borrower expressly consents to the foregoing arrangements and agrees that any Person holding such a participation in the Obligations deemed to have been so purchased may exercise any and all rights of banker’s lien, setoff or counterclaim with respect to any and all moneys owing by the Borrower to such Person as fully as if such Person had made a Loan directly to the Borrower in the amount of such participation.

§30. FINAL AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

§31. USA PATRIOT ACT. Each Bank hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Bank to identify the Borrower in accordance with the Act.

          IN WITNESS WHEREOF, the undersigned have duly executed this Agreement as of the date first set forth above.
