In the event that any financial statement or Compliance Certificate delivered pursuant to Section 5.1(a), (b) or (c) is shown to be inaccurate (so long as such inaccuracy is discovered within the first anniversary of the Termination Date), and such inaccuracy, if corrected, would have led to the application of a higher Applicable Percentage as set forth on Schedule I, in the case of Revolving Loans, and as set forth on Schedule II, in the case of Term Loans, for any period rather than the Applicable Percentage applied for such period, then (i) the Borrower shall immediately deliver to the Administrative Agent a correct Compliance Certificate for such period, (ii) the Applicable Percentage shall be determined based upon the corrected Compliance Certificate and (iii) the Borrowers shall immediately pay to the Administrative Agent, for the account of the Lenders, the accrued additional interest owing as a result of such increased Applicable Percentage for such period.

Until such time as such Lender makes its required payment, the Swingline Lender shall be deemed to continue to have outstanding Swingline Loans in the amount of the unpaid participation for all purposes of the Loan Documents. In addition, such Lender shall be deemed to have assigned any and all payments made of principal and interest on its Loans and any other amounts due to it hereunder, to the Swingline Lender to fund the amount of such Lender’s participation interest in such Swingline Loans that such Lender failed to fund pursuant to this Section 2.4, until such amount has been purchased in full.

If such corresponding amount is not in fact made available to the Administrative Agent by such Lender on the date of such Borrowing, the Administrative Agent shall be entitled to recover such corresponding amount on demand from such Lender together with interest at the Federal Funds Rate until the second Business Day after such demand and thereafter at the Base Rate.

No conversion of any Eurodollar Loans shall be permitted except on the last day of the Interest Period in respect thereof.

Interest on all outstanding Eurodollar Loans shall be payable on the last day of each Interest Period applicable thereto, and, in the case of any Eurodollar Loans having an Interest Period in excess of three months or 90 days, respectively, on each day which occurs every three months or 90 days, as the case may be, after the initial date of such Interest Period, and on the Revolving Commitment Termination Date or the Maturity Date, as the case may be. Interest on each Swingline Loan (other than a Swingline Loan that is a Base Rate Loan which shall be payable as set forth above) shall be payable on the maturity date of such Loan, which shall be the last day of the Interest Period applicable thereto, and on the Revolving Commitment Termination Date. Interest on any Loan which is converted into a Loan of another Type or which is repaid or prepaid shall be payable on the date of such conversion or on the date of any such repayment or prepayment (on the amount repaid or prepaid) thereof. All Default Interest shall be payable on demand.

(e) The Administrative Agent shall determine each interest rate applicable to the Loans hereunder and shall promptly notify the Borrower and the Lenders of such rate in writing (or by telephone, promptly confirmed in writing). Any such determination shall be conclusive and binding for all purposes, absent manifest error.

Section 2.14. Fees.

(a) The Borrower shall pay to the Administrative Agent for its own account fees in the amounts and at the times previously agreed upon in writing by the Borrower and the Administrative Agent.

(b) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a facility fee, which shall accrue at the Applicable Percentage per annum (determined daily in accordance with Schedule I) on the daily amount of the Revolving

Commitment (whether used or unused) of such Lender during the Availability Period; provided, that if such Lender continues to have any Revolving Credit Exposure after the Revolving Commitment Termination Date, then the facility fee shall continue to accrue on the daily amount of such Revolving Credit Exposure from and after the Revolving Commitment Termination Date to the date that all of such Lender’s Revolving Credit Exposure has been paid in full.

(c) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee, which shall accrue at the Applicable Percentage per annum (determined daily in accordance with Schedule I) on the daily amount of the unused Term Loan Commitment of such Lender during the Term Loan Commitment Availability Period.

(d) The Borrower agrees to pay (i) quarterly in arrears to the Administrative Agent, for the account of each Lender, a letter of credit fee with respect to its participation in each Letter of Credit, which shall accrue at a rate per annum equal to the Applicable Margin for Eurodollar Loans then in effect on the average daily amount of such Lender’s LC Exposure attributable to such Letter of Credit during the period from and including the date of issuance of such Letter of Credit to but excluding the date on which such Letter of Credit expires or is drawn in full (including without limitation any LC Exposure that remains outstanding after the Revolving Commitment Termination Date) and (ii) to the Issuing Bank for its own account a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the Availability Period (or until the date that such Letter of Credit is irrevocably cancelled, whichever is later), as well as the Issuing Bank’s standard fees with respect to issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Notwithstanding the foregoing, if the Required Lenders elect to increase the interest rate on the Loans to the Default Interest pursuant to Section 2.13(c), the rate per annum used to calculate the letter of credit fee pursuant to clause (i) above shall automatically be increased by an additional 2% per annum.

(e) The Borrower shall pay to the Administrative Agent, for the ratable benefit of each Lender, the upfront fee previously agreed upon by the Borrower and the Administrative Agent, which shall be due and payable on the Closing Date.

(f) Accrued fees under paragraphs (b), (c) and above shall be payable quarterly in arrears on the last day of each March, June, September and December, commencing on March 31, 2007 and on the Revolving Commitment Termination Date (and if later, the date the Loans and LC Exposure shall be repaid in their entirety); provided further, that any such fees accruing after the Revolving Commitment Termination Date shall be payable on demand.

Section 2.15. Computation of Interest and Fees.

All computations of interest based on the Base Rate shall be made by the Administrative Agent on the basis of a year of 365 days, as the case may be, and all computations of interest based on LIBOR or the Federal Funds Rate and of fees hereunder shall be made on the basis of a year of 360 days for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable (to the extent computed on the basis of days elapsed). Each determination by the Administrative

Agent of an interest amount or fee hereunder shall be made in good faith and, except for manifest error, shall be final, conclusive and binding for all purposes.

Section 2.16. Inability to Determine Interest Rates. If prior to the commencement of any Interest Period for any Eurodollar Borrowing,

(i) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant interbank market, adequate means do not exist for ascertaining LIBOR for such Interest Period, or

(ii) the Administrative Agent shall have received notice from the Required Lenders that the Adjusted LIBO Rate does not adequately and fairly reflect the cost to such Lenders (or Lender, as the case may be) of making, funding or maintaining their (or its, as the case may be) Eurodollar Loans for such Interest Period,

the Administrative Agent shall give written notice (or telephonic notice, promptly confirmed in writing) to the Borrower and to the Lenders as soon as practicable thereafter. Until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) the obligations of the Lenders to make Eurodollar Revolving Loans or to continue or convert outstanding Loans as or into Eurodollar Loans shall be suspended and (ii) all such affected Loans shall be converted into Base Rate Loans on the last day of the then current Interest Period applicable thereto unless the Borrower prepays such Loans in accordance with this Agreement. Unless the Borrower notifies the Administrative Agent at least one Business Day before the date of any Eurodollar Revolving Borrowing for which a Notice of Revolving Borrowing has previously been given that it elects not to borrow on such date, then such Revolving Borrowing shall be made as a Base Rate Borrowing.

Section 2.17. Illegality. If, after the date of this Agreement, any Change in Law shall make it unlawful or impossible for any Lender to make, maintain or fund any Eurodollar Loan and such Lender shall so promptly notify the Administrative Agent, the Administrative Agent shall promptly give notice thereof to the Borrower and the other Lenders, whereupon until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such suspension no longer exist, the obligation of such Lender to make Eurodollar Revolving Loans, or to continue or convert outstanding Loans as or into Eurodollar Loans, shall be suspended. In the case of the making of a Eurodollar Revolving Borrowing, such Lender’s Revolving Loan shall be made as a Base Rate Loan as part of the same Revolving Borrowing for the same Interest Period and if the affected Eurodollar Loan is then outstanding, such Loan shall be converted to a Base Rate Loan either (i) on the last day of the then current Interest Period applicable to such Eurodollar Loan if such Lender may lawfully continue to maintain such Loan to such date or (ii) immediately if such Lender shall determine that it may not lawfully continue to maintain such Eurodollar Loan to such date. Notwithstanding the foregoing, the affected Lender shall, prior to giving such notice to the Administrative Agent, designate a different Applicable Lending Office if such designation would avoid the need for giving such notice and if such designation would not otherwise be disadvantageous to such Lender in the good faith exercise of its discretion.

Section 2.18. Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement that is not otherwise included in the determination of the Adjusted LIBO Rate hereunder against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or the Issuing Bank; or

(ii) impose on any Lender or on the Issuing Bank or the eurodollar interbank market any other condition affecting this Agreement or any Eurodollar Loans made by such Lender or any Letter of Credit or any participation therein;

and the result of either of the foregoing is to increase the cost to such Lender of making, converting into, continuing or maintaining a Eurodollar Loan or to increase the cost to such Lender or the Issuing Bank of participating in or issuing any Letter of Credit or to reduce the amount received or receivable by such Lender or the Issuing Bank hereunder (whether of principal, interest or any other amount), then the Borrower shall promptly pay, upon written notice from and demand by such Lender on the Borrower (with a copy of such notice and demand to the Administrative Agent), to the Administrative Agent for the account of such Lender, within five Business Days after the date of such notice and demand, additional amount or amounts sufficient to compensate such Lender or the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered; provided, that amounts paid under this Section 2.18(a) shall be without duplication of amounts paid under Section 2.20 and shall not include Excluded Taxes.

(b) If any Lender or the Issuing Bank shall have determined that on or after the date of this Agreement any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital (or on the capital of such Lender’s or the Issuing Bank’s parent corporation) as a consequence of its obligations hereunder or under or in respect of any Letter of Credit to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s parent corporation could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies or the policies of such Lender’s or the Issuing Bank’s parent corporation with respect to capital adequacy) then, from time to time, within five (5) Business Days after receipt by the Borrower of written demand by such Lender (with a copy thereof to the Administrative Agent), the Borrower shall pay to such Lender such additional amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s parent corporation for any such reduction suffered.

(c) A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s parent corporation, as the case may be, specified in paragraph (a) or (b) of this Section 2.18 shall be delivered to the Borrower (with a copy to the Administrative Agent) and shall be conclusive, absent manifest error. The Borrower shall pay any such Lender or the Issuing Bank, as the case may be, such amount or amounts within 10 days after receipt thereof.

(d) Except as provided in Section 2.18(e), failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 2.18 shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation;

(e) Notwithstanding anything to the contrary in this Section 2.18, the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section 2.18 for any amounts incurred prior to the date that such Lender or the Issuing Bank notifies the Borrower of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided that, if the circumstances giving rise to such claim have a retroactive effect, then such six-month period shall be extended to include the period of such retroactive effect.

Section 2.19. Funding Indemnity. In the event of (a) the payment of any principal of a Eurodollar Loan other than on the last day of the Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion or continuation of a Eurodollar Loan other than on the last day of the Interest Period applicable thereto, or (c) the failure by the Borrower to borrow, prepay, convert or continue any Eurodollar Loan on the date specified in any applicable notice (regardless of whether such notice is withdrawn or revoked), then, in any such event, the Borrower shall compensate each Lender, within five (5) Business Days after written demand from such Lender, for any loss, cost or expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense shall be deemed to include an amount determined by such Lender to be the excess, if any, of (A) the amount of interest that would have accrued on the principal amount of such Eurodollar Loan if such event had not occurred at the Adjusted LIBO Rate applicable to such Eurodollar Loan for the period from the date of such event to the last day of the then current Interest Period therefor (or in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Eurodollar Loan) over (B) the amount of interest that would accrue on the principal amount of such Eurodollar Loan for the same period if the Adjusted LIBO Rate were set on the date such Eurodollar Loan was prepaid or converted or the date on which the Borrower failed to borrow, convert or continue such Eurodollar Loan. A certificate as to any additional amount payable under this Section 2.19 submitted to the Borrower by any Lender (with a copy to the Administrative Agent) shall be conclusive, absent manifest error.

Section 2.20. Taxes.

(a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided, that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.20) the Administrative Agent, any Lender or the Issuing Bank (as the case may be) shall receive an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within five (5) Business Days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 2.20) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the Code or any treaty to which the United States is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate. Without limiting the generality of the foregoing, each Foreign Lender agrees that it will deliver to the Administrative Agent and the Borrower (or in the case of a Participant, to the Lender from which the related participation shall have been purchased), as appropriate, two (2) duly completed copies of (i) Internal Revenue Service Form W-8 ECI, or any successor form thereto, certifying that the payments received from the Borrower hereunder are effectively connected with such Foreign Lender’s conduct of a trade or business in the United States; or (ii) Internal Revenue Service Form W-8 BEN, or any successor form thereto, certifying that such Foreign Lender is entitled to benefits under an income tax treaty to which the United States is a party which reduces the rate of withholding tax on payments of interest; or (iii) Internal Revenue Service Form W-8 BEN, or any successor form prescribed by the Internal Revenue Service, together with a certificate (A) establishing that the payment to the Foreign Lender qualifies as “portfolio interest” exempt from U.S. withholding tax under Code section 871(h) or 881(c), and (B) stating that (1) the Foreign Lender is not a bank for purposes of Code section 881(c)(3)(A), or the obligation of the Borrower hereunder is not, with respect to such Foreign Lender, a loan agreement entered into in the ordinary course of its trade or business, within the meaning of that section; (2) the Foreign Lender is not a 10% shareholder of the Borrower within the meaning of Code section 871(h)(3) or 881(c)(3)(B); and (3) the Foreign Lender is not a controlled foreign corporation that is related to the Borrower within the meaning of Code section 881(c)(3)(C); or (iv) such other Internal Revenue Service forms as may be applicable to the Foreign Lender, including Forms W-8 IMY or W-8 EXP. Each such Foreign Lender shall deliver to the Borrower and the Administrative Agent such forms on or before the date that it becomes a party to this Agreement (or in the case of a Participant, on or before the date such Participant purchases the related participation). In addition, each such Foreign Lender shall deliver such

forms promptly upon the obsolescence or invalidity of any form previously delivered by such Foreign Lender. Each such Foreign Lender shall promptly notify the Borrower and the Administrative Agent at any time that it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by the Internal Revenue Service for such purpose).

(f) For any period with respect to which a Foreign Lender has failed to provide the Borrower with the appropriate form, certificate or other document described in Section 2.20(e) (other than if such failure is due to a Change in Law, occurring subsequent to the date on which a form, certificate or other document originally was required to be provided, or if such form, certificate or other document otherwise is not required under subsection (e) above), such Foreign Lender shall not be entitled to the additional payment or indemnification under Section 2.20(a) or (c) with respect to Taxes imposed by the United States by reason of such failure; provided, however, that should a Lender become subject to Taxes because of its failure to deliver a form, certificate or other document required hereunder, the Borrower shall take such steps as the Foreign Lender shall reasonably request to assist the Foreign Lender to recover such Taxes.

(g) If the Administrative Agent or any Lender determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid amounts pursuant to this Section 2.20, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.20 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant governmental authority with respect to such refund); provided, that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant governmental authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such governmental authority. This paragraph shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

Section 2.21. Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Sections 2.18, 2.19 or 2.20, or otherwise) prior to 12:00 noon (New Yorktime) on the date when due, in immediately available funds, free and clear of any defenses, rights of set-off, counterclaim, or withholding or deduction of taxes. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at the Payment Office, except payments to be made directly to the Issuing Bank or Swingline Lender as expressly provided herein and except that payments pursuant to Sections 2.18, 2.19 and 2.20 and 10.3 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such

payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be made payable for the period of such extension. All payments hereunder shall be made in Dollars.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements or Swingline Loans that would result in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and Swingline Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements and Swingline Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements and Swingline Loans; provided, that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements or Swingline Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount or amounts due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand

the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.4(c) and (d), 2.6(a), 2.21(d), 2.22(d) or (e) or 10.3(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

Section 2.22. Letters of Credit.

(a) During the Availability Period, the Issuing Bank, in reliance upon the agreements of the other Lenders pursuant to Section 2.22(d), agrees to issue, at the request of the Borrower, Letters of Credit for the account of the Borrower on the terms and conditions hereinafter set forth; provided, that (i) each Letter of Credit shall expire on the earlier of (A) the date one year after the date of issuance of such Letter of Credit (or in the case of any renewal or extension thereof, one year after such renewal or extension) and (B) the date that is five (5) Business Days prior to the Revolving Commitment Termination Date; (ii) each Letter of Credit shall be in a stated amount of at least $100,000; and (iii) the Borrower may not request any Letter of Credit, if, after giving effect to such issuance (A) the aggregate LC Exposure would exceed the LC Commitment or (B) the aggregate Revolving Credit Exposure of all Lenders would exceed the Aggregate Revolving Commitment Amount. Each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Issuing Bank without recourse a participation in each Letter of Credit equal to such Lender’s Pro Rata Share of the aggregate amount available to be drawn under such Letter of Credit on the date of issuance with respect to all other Letters of Credit. Each issuance of a Letter of Credit shall be deemed to utilize the Revolving Commitment of each Lender by an amount equal to the amount of such participation.

(b) To request the issuance of a Letter of Credit (or any amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall give the Issuing Bank and the Administrative Agent irrevocable written notice at least three (3) Business Days prior to the requested date of such issuance specifying the date (which shall be a Business Day) such Letter of Credit is to be issued (or amended, extended or renewed, as the case may be), the expiration date of such Letter of Credit, the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. In addition to the satisfaction of the conditions in Article III, the issuance of such Letter of Credit (or any amendment which increases the amount of such Letter of Credit) will be subject to the further conditions that such Letter of Credit shall be in such form and contain such terms as the Issuing Bank shall approve and that the Borrower shall have executed and delivered any additional applications, agreements and instruments relating to such Letter of Credit as the Issuing Bank shall reasonably require; provided, that in the event of any conflict between such applications, agreements or instruments and this Agreement, the terms of this Agreement shall control.

(c) At least two Business Days prior to the issuance of any Letter of Credit, the Issuing Bank will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received such notice and if not, the Issuing Bank will provide the Administrative Agent with a copy thereof. Unless the Issuing Bank has received notice from the Administrative Agent on or before the Business Day immediately preceding the date the Issuing Bank is to issue the requested Letter of Credit (1) directing the Issuing Bank not to issue the Letter of Credit because such issuance is not then permitted hereunder because of the limitations set forth in Section 2.22(a) or that one or more conditions specified in Article III are not then satisfied, then, subject to the terms and conditions hereof, the Issuing Bank shall, on the requested date, issue such Letter of Credit in accordance with the Issuing Bank’s usual and customary business practices.

(d) The Issuing Bank shall examine all documents purporting to represent a demand for payment under a Letter of Credit promptly following its receipt thereof. The Issuing Bank shall notify the Borrower and the Administrative Agent of such demand for payment and whether the Issuing Bank has made or will make a LC Disbursement thereunder; provided, that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to such LC Disbursement. The Borrower shall be irrevocably and unconditionally obligated to reimburse the Issuing Bank for any LC Disbursements paid by the Issuing Bank in respect of such drawing, without presentment, demand or other formalities of any kind. Unless the Borrower shall have notified the Issuing Bank and the Administrative Agent prior to 11:00 a.m. (New Yorktime) on the Business Day immediately prior to the date on which such drawing is honored that the Borrower intends to reimburse the Issuing Bank for the amount of such drawing in funds other than from the proceeds of Revolving Loans, the Borrower shall be deemed to have timely given a Notice of Revolving Borrowing to the Administrative Agent requesting the Lenders to make a Base Rate Borrowingon the date on which such drawing is honored in an exact amount due to the Issuing Bank; provided, that for purposes solely of such Borrowing, the conditions precedent set forth in Section 3.2 hereof shall not be applicable. The Administrative Agent shall notify the Lenders of such Borrowing in accordance with Section 2.3, and each Lender shall make the proceeds of its Base Rate Loan included in such Borrowing available to the Administrative Agent for the account of the Issuing Bank in accordance with Section 2.6. The proceeds of such Borrowing shall be applied directly by the Administrative Agent to reimburse the Issuing Bank for such LC Disbursement.

(e) If for any reason a Base Rate Borrowing may not be (as determined in the sole discretion of the Administrative Agent), or is not, made in accordance with the foregoing provisions, then each Lender (other than the Issuing Bank) shall be obligated to fund the participation that such Lender purchased pursuant to subsection (a) in an amount equal to its Pro Rata Shareof such LC Disbursement on and as of the date which such Base Rate Borrowing should have occurred. Each Lender’s obligation to fund its participation shall be absolute and unconditional and shall not be affected by any circumstance, including without limitation (i) any setoff, counterclaim, recoupment, defense or other right that such Lender or any other Person may have against the Issuing Bank or any other Person for any reason whatsoever, (ii) the existence of a Default or an Event of Default or the termination of the Aggregate Revolving Commitments, (iii) any adverse change in the condition (financial or otherwise) of the Borrower or any of its Subsidiaries, (iv) any breach of this Agreement by the Borrower or any other

Lender, (v) any amendment, renewal or extension of any Letter of Credit or (vi) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. On the date that such participation is required to be funded, each Lender shall promptly transfer, in immediately available funds, the amount of its participation to the Administrative Agent for the account of the Issuing Bank. Whenever, at any time after the Issuing Bank has received from any such Lender the funds for its participation in a LC Disbursement, the Issuing Bank (or the Administrative Agent on its behalf) receives any payment on account thereof, the Administrative Agent or the Issuing Bank, as the case may be, will distribute to such Lender its Pro Rata Share of such payment; provided, that if such payment is required to be returned for any reason to the Borrower or to a trustee, receiver, liquidator, custodian or similar official in any bankruptcy proceeding, such Lender will return to the Administrative Agent or the Issuing Bank any portion thereof previously distributed by the Administrative Agent or the Issuing Bank to it.

(f) To the extent that any Lender shall fail to pay any amount required to be paid pursuant to paragraphs (d) or (e) of this Section on the due date therefor, such Lender shall pay interest to the Issuing Bank (through the Administrative Agent) on such amount from such due date to the date such payment is made at a rate per annum equal to the Federal Funds Rate; provided, that if such Lender shall fail to make such payment to the Issuing Bank within three (3) Business Days of such due date, then, retroactively to the due date, such Lender shall be obligated to pay interest on such amount at the rate set forth in Section 2.13(d).

(g) If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives notice from the Administrative Agent or the Required Lenders demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Issuing Bank and the Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid fees thereon; provided, that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (g) or (h) of Section 8.1. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Borrower agrees to execute any documents and/or certificates to effectuate the intent of this paragraph. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest and profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it had not been reimbursed and to the extent so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated, with the consent of the Required Lenders, be applied to satisfy other obligations of the Borrower under this Agreement and the other Loan Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not so applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived.

(h) Promptly following the end of each calendar quarter, the Issuing Bank shall deliver (through the Administrative Agent) to each Lender and the Borrower a report describing the aggregate Letters of Credit outstanding at the end of such Fiscal Quarter. Upon the request of any Lender from time to time, the Issuing Bank shall deliver to such Lender any other information reasonably requested by such Lender with respect to each Letter of Credit then outstanding.

(i) The Borrower’s obligation to reimburse LC Disbursements hereunder shall be absolute, unconditional and irrevocable and shall be performed strictly in accordance with the terms of this Agreement under all circumstances whatsoever and irrespective of any of the following circumstances:

(i) Any lack of validity or enforceability of any Letter of Credit or this Agreement;

(ii) The existence of any claim, set-off, defense or other right which the Borrower or any Subsidiary or Affiliate of the Borrower may have at any time against a beneficiary or any transferee of any Letter of Credit (or any Persons or entities for whom any such beneficiary or transferee may be acting), any Lender (including the Issuing Bank) or any other Person, whether in connection with this Agreement or the Letter of Credit or any document related hereto or thereto or any unrelated transaction;

(iii) Any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect;

(iv) Payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document to the Issuing Bank that does not comply with the terms of such Letter of Credit;

(v) Any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.22, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder; or

(vi) The existence of a Default or an Event of Default.

Neither the Administrative Agent, the Issuing Bank, the Lenders nor any Related Party of any of the foregoing shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to above), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided, that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any actual direct damages (as opposed to special, indirect (including claims for lost profits or other consequential damages), or punitive damages, claims in respect of which are hereby waived by the Borrower to

the extent permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s failure to exercise due care when determining whether drafts or other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree, that in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised due care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented that appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(j) Unless otherwise expressly agreed by the Issuing Bank and the Borrower when a Letter of Credit is issued and subject to applicable laws, performance under Letters of Credit by the Issuing Bank, its correspondents, and the beneficiaries thereof will be governed by (i) either (x) the rules of the “International Standby Practices 1998” (ISP98) (or such later revision as may be published by the Institute of International Banking Law & Practice on any date any Letter of Credit may be issued) or (y) the rules of the “Uniform Customs and Practices for Documentary Credits” (1993 Revision), International Chamber of Commerce Publication No. 500 (or such later revision as may be published by the International Chamber of Commerce on any date any Letter of Credit may be issued) and (ii) to the extent not inconsistent therewith, the governing law of this Agreement set forth in Section 10.5.

Section 2.23. Increase of Commitments; Additional Lenders.

(a) So long as no Event of Default has occurred and is continuing, from time to time after the Closing Date, Borrower may, upon at least 30 days’ written notice to the Administrative Agent (who shall promptly provide a copy of such notice to each Lender), propose to increase the Commitments by an additional $100,000,000 (the amount of any such increase, the “Additional Commitment Amount”). Each Lender shall have the right for a period of 15 days following receipt of such notice, to elect by written notice to the Borrower and the Administrative Agent to increase its Commitment by a principal amount equal to its Pro Rata Share of the Additional Commitment Amount. No Lender (or any successor thereto) shall have any obligation to increase its Commitment or its other obligations under this Agreement and the other Loan Documents, and any decision by a Lender to increase its Commitment shall be made in its sole discretion independently from any other Lender.

(b) If any Lender shall not elect to increase its Commitment pursuant to subsection (a) of this Section 2.23, the Borrower may designate another bank or other financial institution (which may be, but need not be, one or more of the existing Lenders) which at the time agrees to, in the case of any such Person that is an existing Lender, increase its Revolving Commitment and in the case of any other such Person (an “Additional Lender”), become a party to this Agreement; provided, however, that any new bank or financial institution must be acceptable to the Administrative Agent, which acceptance will not be unreasonably withheld or delayed. The sum of the increases in the Commitments of the existing Lenders pursuant to this

subsection (b) plus the Commitments of the Additional Lenders shall not in the aggregate exceed the unsubscribed amount of the Additional Commitment Amount.

(c) An increase in the aggregate amount of the Commitments pursuant to this Section 2.23 shall become effective upon the receipt by the Administrative Agent of an supplement or joinder in form and substance satisfactory to the Administrative Agent executed by the Borrower, by each Additional Lender and by each other Lender whose Revolving Commitment is to be increased, setting forth the new Commitments of such Lenders and setting forth the agreement of each Additional Lender to become a party to this Agreement and to be bound by all the terms and provisions hereof, together with Notes evidencing such increase in the Commitments, and such evidence of appropriate corporate authorization on the part of the Borrower with respect to the increase in the Commitments and such opinions of counsel for the Borrower with respect to the increase in the Commitments as the Administrative Agent may reasonably request.

(d) Upon the acceptance of any such supplement or joinder by the Administrative Agent, the Commitments shall automatically be increased by the amount of the Commitments added through such supplement or joinder and Schedule III shall automatically be deemed amended to reflect the Commitments of all Lenders after giving effect to the addition of such Commitments.

(e) Upon any increase in the aggregate amount of the Commitments pursuant to this Section 2.23 that is not pro rata among all Lenders, (x) within five Business Days, in the case of any Base Rate Loans then outstanding, and at the end of the then current Interest Period with respect thereto, in the case of any Eurodollar Loans then outstanding, the Borrower shall prepay such Loans in their entirety and, to the extent the Borrower elects to do so and subject to the conditions specified in Article III, the Borrower shall reborrow Loans from the Lenders in proportion to their respective Commitments after giving effect to such increase, until such time as all outstanding Loans are held by the Lenders in proportion to their respective Commitments after giving effect to such increase and (y) effective upon such increase, the amount of the participations held by each Lender in each Letter of Credit then outstanding shall be adjusted automatically such that, after giving effect to such adjustments, the Lenders shall hold participations in each such Letter of Credit in proportion to their respective Commitments.

Section 2.24. Mitigation of Obligations. If any Lender requests compensation under Section 2.18, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.20, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the sole judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable under Section 2.18 or Section 2.20, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all costs and expenses incurred by any Lender in connection with such designation or assignment.

Section 2.25. Replacement of Lenders. If any Lender requests compensation under Section 2.18, or if the Borrower is required to pay any additional amount to any Lender or any

Governmental Authority of the account of any Lender pursuant to Section 2.20, or if any Lender defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions set forth in Section 10.4(b) all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender); provided, that (i) the Borrower shall have received the prior written consent of the Administrative Agent with respect to the proposed assignee, which consent shall not be unreasonably withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal amount of all Loans and participations in Letters of Credit owed to it, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (in the case of such outstanding principal and accrued interest) and from the Borrower (in the case of all other amounts) and (iii) in the case of a claim for compensation under Section 2.18 or payments required to be made pursuant to Section 2.20, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

Section 2.26. Extensions of Maturity Date or Revolving Commitment Termination Date.

After the first anniversary of the Closing Date and at least 45 days prior to the scheduled Maturity Date and Revolving Commitment Termination Date then in effect, the Borrower may (but in no event more than once per year or twice during the term of this Agreement), by written notice to the Administrative Agent, request that the scheduled Maturity Date and Revolving Commitment Termination Date then in effect be extended for a twelve-month period, effective as of a date selected by the Borrower (the “Extension Effective Date”); the Extension Effective Date shall be at least 45 days, but not more than 60 days, after the date such extension request is received by the Administrative Agent (the “Extension Request Date”). Upon receipt of the extension request, the Administrative Agent shall promptly notify each Lender thereof, and approval by the Required Lenders shall be necessary for the extension to become effective. If a Lender agrees, in its individual and sole discretion, to so extend its Revolving Credit Commitment or Maturity Date, as applicable, (an “Extending Lender”), it shall deliver to the Administrative Agent a written notice of its agreement to do so no later than 15 days after the Extension Request Date (or such later date to which the Borrower and the Administrative Agent shall agree), and the Administrative Agent shall promptly thereafter notify the Borrower of such Extending Lender’s agreement to extend its Revolving Credit Commitment or Maturity Date, as applicable, (and such agreement shall be irrevocable until the Extension Effective Date). The Revolving Credit Commitment or Term Loan Commitment of any Lender that fails to accept or respond to the Borrower’s request for extension of the Maturity Date and Revolving Commitment Termination Date (a “Declining Lender”) shall be terminated on the Maturity Date and Revolving Commitment Termination Date then in effect for such Lender (without regard to any extension by other Lenders) and on such Maturity Date and Revolving Commitment Termination Date the Borrower shall pay in full the unpaid principal amount of all Loans owing to such Declining Lender, together with all accrued and unpaid interest thereon and all fees accrued and unpaid under this Agreement to the date of such payment of principal and all other amounts due to such Declining Lender under this Agreement. The Administrative Agent shall promptly notify each Extending Lender of the aggregate Commitments of the Declining Lenders.

Each Extending Lender may offer to increase its respective Commitment by an amount not to exceed the aggregate amount of the Declining Lenders’ Commitments, and such Extending Lender shall deliver to the Administrative Agent a notice of its offer to so increase its Commitment no later than 30 days after the Extension Request Date (or such later date to which the Borrower and the Administrative Agent shall agree), and such offer shall be irrevocable until the Extension Effective Date. To the extent the aggregate amount of additional Commitments that the Extending Lenders offer pursuant to the preceding sentence exceeds the aggregate amount of the Declining Lenders’ Commitments, such additional Commitments shall be reduced on a pro rata basis. To the extent the aggregate amount of Commitments that the Extending Lenders have so offered to extend is less than the aggregate amount of Commitments that the Borrower has so requested to be extended, the Borrower shall have the right but not the obligation to require any Declining Lender to (and any such Declining Lender shall) assign in full its rights and obligations under this Agreement to one or more banks or other financial institutions (which may be, but need not be, one or more of the Extending Lenders) which at the time agree to, in the case of any such Person that is an Extending Lender, increase its Commitment and in the case of any other such Person (a “New Lender”) become a party to this Agreement; provided that (i) such assignment is otherwise in compliance with Section 10.04, (ii) such Declining Lender receives payment in full of the unpaid principal amount of all Loans owing to such Declining Lender, together with all accrued and unpaid interest thereon and all fees accrued and unpaid under this Agreement to the date of such payment of principal and all other amounts due to such Declining Lender under this Agreement and (iii) any such assignment shall be effective on the date on or before such Extension Effective Date as may be specified by the Borrower and agreed to by the respective New Lenders and Extending Lenders, as the case may be, and the Administrative Agent. If, but only if, Extending Lenders and New Lenders, as the case may be, have agreed to provide Commitments in an aggregate amount greater than 50% of the aggregate amount of the Commitments outstanding immediately prior to such Extension Effective Date and the conditions precedent in Section 3.2 are met, the Termination Date in effect with respect to such Extending Lenders and New Lenders shall be extended by twelve months.

audit adjustments and the absence of footnotes in the case of the statements referred to in clause (ii).

FINANCIAL COVENANTS

Until the Termination Date, the Borrower covenants and agrees that:

Section 6.1. Leverage Ratio. (a) The Borrower and its Subsidiaries will maintain on a consolidated basis as of the end of each Fiscal Quarter, commencing with the Fiscal Quarter ending December 31, 2006, a Leverage Ratio of not greater than 4.75:1.00 (the “Required Threshold”), provided, however, that if the Borrower consummates one or more acquisitions permitted under this Agreement in which the aggregate purchase price of all such acquisitions is $25,000,000 or more, then the Required Threshold shall be increased to 5.50 to 1.00 for the first three fiscal reporting periods during any 12-month period immediately following the consummation of such acquisitions; provided, however that in determining compliance with the Leverage Ratio, TransCanada Subordinated Debt in an amount not to exceed $300,000,000 shall not be included in such calculation. The Borrower’s compliance with this requirement shall be calculated on a rolling four quarter basis, measured on the last day of each fiscal quarter. For purposes of the foregoing, to the extent Consolidated Total Funded Debt includes outstanding amounts under Hybrid Securities, then a portion of the amount of such Hybrid Securities not to exceed a total of 15% of Total Capitalization may be excluded from Consolidated Total Funded Debt (the “Excluded Hybrid Securities”).

(b) Notwithstanding the forgoing, the Borrower may elect, after giving effect to the GLGT Acquisition, to increase the Required Threshold to 6.00 to 1.00 through the Fiscal Quarter ending September 30, 2007 (and the Borrower shall be deemed to have made such an election at the time the aggregate principal amount of the Loans outstanding exceeds $880,000,000; provided that such increase in the principal amount of the Loans outstanding is a result of the proceeds of such Loans being used to consummate the GLGT Acquisition). If the Borrower makes such an election to increase the Required Threshold (i) the Applicable Margin for Revolving Eurodollar Loans shall be 0.95% per annum and the Applicable Margin for Revolving Base Rate Loans shall be 0.50% per

annum, (ii) the Applicable Percentage for the Facility Fee for Revolving Loans shall be 0.20% per annum, (iii) the Utilization Premium shall be 0.10% per annum, (iv) the Applicable Margin for Term Loan Eurodollar Loans shall be 1.25% per annum and the Applicable Margin for Term Loan Base Rate Loans shall be 0.50% per annum, and (v) the Applicable Percentage for the Commitment Fee for Term Loans shall be 0.20% per annum, until such time as the Leverage Ratio of the Borrower and its Subsidiaries is 5.50:1.00. Solely for the purposes of determining the Leverage Ratio pursuant to the immediately preceding sentence, Adjusted Cash Flow shall be deemed to be $174,000,000 until the delivery of the first Compliance Certificate following the closing of the GLGT Acquisition (the “First Compliance Certificate”); provided that in the event that the First Compliance Certificate reflects a Leverage Ratio in excess of 5.50:1.00, the Borrower shall immediately pay to the Administrative Agent for the account of the Lenders the accrued additional interest that would have been owed during the prior period as if the Borrower had never achieved a Leverage Ratio equal to or less than 5.50:1.00. Notwithstanding the foregoing, if the Borrower makes the election to increase the Required Threshold as provided for above, the Borrower and its Subsidiaries will be required to maintain, on a consolidated basis as of the end of each Fiscal Quarter, commencing with the Fiscal Quarter ending December 31, 2007, a Leverage Ratio of not greater than 4.75:1.00, subject to allowances for temporary increases in the Required Threshold to 5.50:1.00 as provided in Section 6.1(a) above.

The Borrower and its Subsidiaries will maintain on a consolidated basis as of the end of each Fiscal Quarter, commencing with the Fiscal Quarter ending December 31, 2006, an Interest Coverage Ratio of not less than 3.00:1.00. For the purposes of the foregoing, to the extent Consolidated Interest Expense includes interest expense under Excluded Hybrid Securities, then an amount equal to such interest expense multiplied by the Xxxxx’x Equity Credit shall be excluded from Consolidated Interest Expense. In determining compliance with the Interest Coverage Ratio, interest expense with respect to TransCanada Subordinated Debt shall not be included in such calculation.

ARTICLE IX

THE ADMINISTRATIVE AGENT

Section 9.1. Appointment of Administrative Agent.

(a) Each Lender irrevocably appoints SunTrust Bank as the Administrative Agent and authorizes it to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent under this Agreement and the other Loan Documents, together with all such actions and powers that are reasonably incidental thereto. The Administrative Agent may perform any of its duties hereunder or under the other Loan Documents by or through any one or more sub-agents or attorneys-in-fact appointed by the Administrative Agent. The Administrative Agent and any such sub-agent or attorney-in-fact may perform any and all of its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions set forth in this Article shall apply to any such sub-agent or attorney-in-fact and the Related Parties of the Administrative Agent, any such sub-agent and any such attorney-in-fact and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

(b) The Issuing Bank shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith until such time and except for so long as the Administrative Agent may agree at the request of the Required Lenders to act for the Issuing Bank with respect thereto; provided, that the Issuing Bank shall have all the benefits and immunities (i) provided to the Administrative Agent in this Article with respect to any acts taken or omissions suffered by the Issuing Bank in connection with Letters of Credit issued by it or proposed to be issued by it and the application and agreements for letters of credit pertaining to the Letters of Credit as fully as if the term “Administrative Agent” as used in this Article included the Issuing Bank with respect to such acts or omissions and (ii) as additionally provided in this Agreement with respect to the Issuing Bank.

Section 9.2. Nature of Duties of Administrative Agent. The Administrative Agent shall not have any duties or obligations except those expressly set forth in this Agreement and the other Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or an Event of Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except those discretionary rights and powers expressly contemplated by the Loan Documents that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.2), and (c) except as expressly set forth in the Loan Documents, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it, its sub-agents or attorneys-in-fact with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.2) or in the absence of its own gross negligence or willful

misconduct. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents or attorneys-in-fact selected by it with reasonable care. The Administrative Agent shall not be deemed to have knowledge of any Default or Event of Default unless and until written notice thereof (which notice shall include an express reference to such event being a “Default” or “Event of Default” hereunder) is given to the Administrative Agent by the Borrower or any Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements, or other terms and conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article III or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. The Administrative Agent may consult with legal counsel (including counsel for the Borrower) concerning all matters pertaining to such duties.

Section 9.3. Lack of Reliance on the Administrative Agent. Each of the Lenders, the Swingline Lender and the Issuing Bank acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each of the Lenders, the Swingline Lender and the Issuing Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, continue to make its own decisions in taking or not taking of any action under or based on this Agreement, any related agreement or any document furnished hereunder or thereunder.

Section 9.4. Certain Rights of the Administrative Agent. If the Administrative Agent shall request instructions from the Required Lenders with respect to any action or actions (including the failure to act) in connection with this Agreement, the Administrative Agent shall be entitled to refrain from such act or taking such act, unless and until it shall have received instructions from such Lenders; and the Administrative Agent shall not incur liability to any Person by reason of so refraining. Without limiting the foregoing, no Lender shall have any right of action whatsoever against the Administrative Agent as a result of the Administrative Agent acting or refraining from acting hereunder in accordance with the instructions of the Required Lenders where required by the terms of this Agreement.

Section 9.5. Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, posting or other distribution) believed by it to be genuine and to have been signed, sent or made by the proper Person. The Administrative Agent may also rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or not taken by it in accordance with the advice of such counsel, accountants or experts.

Section 9.6. The Administrative Agent in its Individual Capacity. The bank serving as the Administrative Agent shall have the same rights and powers under this Agreement and any other Loan Document in its capacity as a Lender as any other Lender and may exercise or refrain from exercising the same as though it were not the Administrative Agent; and the terms “Lenders”, “Required Lenders”, “holders of Notes”, or any similar terms shall, unless the context clearly otherwise indicates, include the Administrative Agent in its individual capacity. The bank acting as the Administrative Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower or any Subsidiary or Affiliate of the Borrower as if it were not the Administrative Agent hereunder.

Section 9.7. Successor Administrative Agent.

(a) The Administrative Agent may resign at any time by giving notice thereof to the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent, subject to the approval by the Borrower provided that no Default or Event of Default shall exist at such time. If no successor Administrative Agent shall have been so appointed, and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent, which shall be a commercial bank organized under the laws of the United States of America or any state thereof or a bank which maintains an office in the United States, having a combined capital and surplus of at least $500,000,000.

(b) Upon the acceptance of its appointment as the Administrative Agent hereunder by a successor, 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. If within 45 days after written notice is given of the retiring Administrative Agent’s resignation under this Section 9.7 no successor Administrative Agent shall have been appointed and shall have accepted such appointment, then on such 45th day (i) the retiring Administrative Agent’s resignation shall become effective, (ii) the retiring Administrative Agent shall thereupon be discharged from its duties and obligations under the Loan Documents and (iii) the Required Lenders shall thereafter perform all duties of the retiring Administrative Agent under the Loan Documents until such time as the Required Lenders appoint a successor Administrative Agent as provided above. After any retiring Administrative Agent’s resignation hereunder, the provisions of this Article shall continue in effect for the benefit of such retiring Administrative Agent and its representatives and agents in respect of any actions taken or not taken by any of them while it was serving as the Administrative Agent.

Section 10.2. Waiver; Amendments.

(a) No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder or any other Loan Document, and no course of dealing between the Borrower and the Administrative Agent or any Lender, 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 right or power, preclude any other or further exercise thereof or the exercise of any other right or power hereunder or thereunder. The rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder

and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies provided by law. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section 10.2, and then such 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 the 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 Lender or the Issuing Bank may have had notice or knowledge of such Default or Event of Default at the time.

(b) No amendment or waiver of any provision of this Agreement or the other Loan Documents, nor consent to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Borrower and the Required Lenders or the Borrower and the Administrative Agent with the consent of the Required Lenders and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, that no amendment or waiver shall: (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the date fixed for any payment of any principal of, or interest on, any Loan or LC Disbursement or interest thereon or any fees hereunder or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date for the termination or reduction of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.21(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, or (v) change any of the provisions of this Section 10.2 or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders which are required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the consent of each Lender; provided further, that no such agreement shall amend, modify or otherwise affect the rights, duties or obligations of the Administrative Agent, the Swingline Lender or the Issuing Bank without the prior written consent of such Person. Notwithstanding anything contained herein to the contrary, this Agreement may be amended and restated without the consent of any Lender (but with the consent of the Borrower and the Administrative Agent) if, upon giving effect to such amendment and restatement, such Lender shall no longer be a party to this Agreement (as so amended and restated), the Commitments of such Lender shall have terminated (but such Lender shall continue to be entitled to the benefits of Sections 2.18, 2.19, 2.20 and 10.3), such Lender shall have no other commitment or other obligation hereunder and shall have been paid in full all principal, interest and other amounts owing to it or accrued for its account under this Agreement.

transactions contemplated in this Agreement or any other Loan Document shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all out-of-pocket costs and expenses (including, without limitation, but limited to the reasonable fees, charges and disbursements of one outside counsel for the Administrative Agent, the Issuing Bank and the Lenders) incurred by the Administrative Agent, the Issuing Bank or any Lender in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section 10.3, or in connection with the Loans made or any Letters of Credit issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

(b) The Borrower shall indemnify the Administrative Agent (and any sub-agent thereof), each Lender and the Issuing Bank, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses (including the fees, charges and disbursements of any counsel for any Indemnitee), and shall indemnify and hold harmless each Indemnitee from all fees and time charges and disbursements for attorneys who may be employees of any Indemnitee, incurred by any Indemnitee or asserted against any Indemnitee by any third party or by the Borrower arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or thereby, (ii) any Loan or Letter of Credit or the use or proposed use of the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or Release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by the Borrower, and regardless of whether any Indemnitee is a party thereto, provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or (y) result from a claim brought by the Borrower against an Indemnitee for breach in bad faith of such Indemnitee’s obligations hereunder or under any other Loan Document, if the Borrower has obtained a final judgment in its favor on such claim as determined by a court of competent jurisdiction.

(c) The Borrower shall pay, and hold the Administrative Agent and each of the Lenders harmless from and against, any and all present and future stamp, documentary, and other similar taxes with respect to this Agreement and any other Loan Documents, any collateral described therein, or any payments due thereunder, and save the Administrative Agent and each Lender harmless from and against any and all liabilities with respect to or resulting from any delay or omission to pay such taxes.

(d) To the extent that the Borrower fails to pay any amount required to be paid to the Administrative Agent, the Issuing Bank or the Swingline Lender under clauses (a), (b) or (c) hereof, each Lender severally agrees to pay to the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case may be, such Lender’s Pro Rata Share (determined as of the time that the unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided, that the unreimbursed expense or indemnified payment, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent, the Issuing Bank or the Swingline Lender in its capacity as such.

(e) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to actual or direct damages) arising out of, in connection with or as a result of, this Agreement or any agreement or instrument contemplated hereby, the transactions contemplated therein, any Loan or any Letter of Credit or the use of proceeds thereof.

(f) All amounts due under this Section 10.3 shall be payable promptly after written demand therefor.

Section 10.4. Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B) in any case not described in paragraph (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans and Revolving Credit Exposure outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans and Revolving Credit Exposure of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Acceptance, as of the Trade Date) shall not be less than $1,000,000, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed).

(ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans, Revolving Credit Exposure or the Commitment assigned.

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by paragraph (b)(i)(B) of this Section and, in addition:

(A) the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Defaulthas occurred and is continuing at the time of such assignment or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund;

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments to a Person that is not a Lender with a Commitment; and

(C) the consent of the Issuing Bank (such consent not to be unreasonably withheld or delayed) shall be required for any assignment that increases the obligation of the assignee to participate in exposure under one or more Letters of Credit (whether or not then outstanding), and the consent of the Swingline Lender (such consent not to be unreasonably withheld or delayed) shall be required for any assignment in respect of the Revolving Credit Commitments.

(iv) Assignment and Acceptance. The parties to each assignment shall deliver to the Administrative Agent (A) a duly executed Assignment and Acceptance, (B) a processing and recordation fee of $3,500, (C) an Administrative Questionnaire unless the assignee is already a Lender and (D) the documents required under Section 2.20 if such assignee is a Foreign Lender.

(v) No Assignment to Borrower. No such assignment shall be made to the Borrower or any of the Borrower’s Affiliates or Subsidiaries.

(vi) No Assignment to Natural Persons. No such assignment shall be made to a natural person.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section 10.4, from and after the effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.18, 2.19, 2.20 and 10.3 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section 10.4.

(c) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in Atlanta, Georgia a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amount of the Loans and Revolving Credit Exposure owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). Information contained in the Register with respect to any Lender shall be available for inspection by such Lender at any reasonable time and from time to time upon reasonable prior notice; information contained in the Register shall also be available for inspection by the Borrower at any reasonable time and from time to time upon reasonable prior notice. In establishing and maintaining the Register, Administrative Agent shall serve as Company’s agent solely for tax purposes and solely with respect to the actions described in this Section, and the Borrower hereby agrees that, to the extent SunTrust Bank serves in such capacity, SunTrust Bank and its officers, directors, employees, agents, sub-agents and affiliates shall constitute “Indemnitees.”

(d) Any Lender may at any time, without the consent of, or notice to, the Borrower, the Administrative Agent, the Swingline Lender or the Issuing Bank sell participations to any Person (other than a natural person, the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent, the Lenders, Issuing Bank and Swingline Lender shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement.

(e) Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the

consent of the Participant, agree to any amendment, modification or waiver with respect to the following to the extent affecting such Participant: (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the date fixed for any payment of any principal of, or interest on, any Loan or LC Disbursement or interest thereon or any fees hereunder or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date for the termination or reduction of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.21(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change any of the provisions of this Section 10.4 or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders which are required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the consent of each Lender; or (vi) release all or substantially all collateral (if any) securing any of the Obligations. Subject to paragraph (e) of this Section 10.4, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.18, 2.19, and 2.20 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section 10.4. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.7 as though it were a Lender, provided such Participant agrees to be subject to Section 2.21 as though it were a Lender.

(f) A Participant shall not be entitled to receive any greater payment under Section 2.18 and Section 2.20 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant, after disclosure of such greater payment, is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.20unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.20(e) as though it were a Lender.

(g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Section 10.5. Governing Law; Jurisdiction; Consent to Service of Process.

(a) This Agreement and the other Loan Documents shall be construed in accordance with and be governed by the law (without giving effect to the conflict of law principles thereof except for Sections 5-1401 and 5-1402 of the New York General Obligations Law) of the State of New York.

(b) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the United States District Court of the Southern District of New York, and of the Supreme Court of the State of New York sitting in New York county and any appellate court from any thereof, in any action or proceeding arising out of or

relating to this Agreement or any other Loan Document or the transactions contemplated hereby or thereby, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York state court or, to the extent permitted by applicable law, such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall affect any right that the Administrative Agent, the Issuing Bank or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against the Borrower or its properties in the courts of any jurisdiction.

(c) The Borrower irrevocably and unconditionally waives any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding described in paragraph (b) of this Section 10.5 and brought in any court referred to in paragraph (b) of this Section 10.5. Each of the parties hereto irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to the service of process in the manner provided for notices in Section 10.1. Nothing in this Agreement or in any other Loan Document will affect the right of any party hereto to serve process in any other manner permitted by law.

Section 10.6. WAIVER OF JURY TRIAL. EACH PARTY HERETO IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 10.7. Right of Setoff. In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, each Lender and the Issuing Bank shall have the right, at any time or from time to time upon the occurrence and during the continuance of an Event of Default, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, to set off and apply against all deposits (general or special, time or demand, provisional or final) of the Borrower at any time held or other obligations at any time owing by such Lender or any of its Affiliates and the Issuing Bank to or for the credit or the account of the Borrower against any and all Obligations held by such Lender or the

Issuing Bank, as the case may be, irrespective of whether such Lender or the Issuing Bank shall have made demand hereunder and although such Obligations may be unmatured. Each Lender and the Issuing Bank agree promptly to notify the Administrative Agent and the Borrower after any such set-off and any application made by such Lender and the Issuing Bank, as the case may be; provided, that the failure to give such notice shall not affect the validity of such set-off and application. Each Lender and the Issuing Bank agrees to apply all amounts collected from any such set-off to the Obligations before applying such amounts to any other Indebtedness or other obligations owed by the Borrower and any of its Subsidiaries to such Lender or Issuing Bank.

Section 10.8. Counterparts; Integration. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by telecopy), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. This Agreement, the Fee Letter, the other Loan Documents, and any separate letter agreement(s) relating to any fees payable to the Administrative Agent constitute the entire agreement among the parties hereto and thereto regarding the subject matters hereof and thereof and supersede all prior agreements and understandings, oral or written, regarding such subject matters.

Section 10.9. Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 2.18, 2.19, 2.20, and 10.3 and Article IX shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof provided that the provisions of Sections 2.18, 2.19, and 2.20 shall only survive and remain in full force and effect until the first anniversary of the Termination Date. All representations and warranties made herein, in the certificates, reports, notices, and other documents delivered pursuant to this Agreement shall survive the execution and delivery of this Agreement and the other Loan Documents, and the making of the Loans and the issuance of the Letters of Credit.

Section 10.10. Severability. Any provision of this Agreement or any other Loan Document held to be illegal, invalid or unenforceable in any jurisdiction, shall, as to such jurisdiction, be ineffective to the extent of such illegality, invalidity or unenforceability without affecting the legality, validity or enforceability of the remaining provisions hereof or thereof; and the illegality, invalidity or unenforceability of a particular provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Section 10.11. Confidentiality. Each of the Administrative Agent, the Issuing Bank and each Lender agrees to take normal and reasonable precautions to maintain the confidentiality of any confidential information provided to it by the Borrower or any Subsidiary, except that such information may be disclosed (i) to any Related Party of the Administrative Agent,

the Issuing Bank or any such Lender, including without limitation accountants, legal counsel and other advisors with a reasonable need for such information (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such information and instructed to keep such information confidential on substantially the same terms as provided herein), (ii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iii) to the extent requested by any regulatory agency or authority or self-regulatory body having or claiming authority to regulate or oversee any aspect of the Administrative Agent’s or any Lender’s business or businesses, (iv) to the extent that such information becomes publicly available other than as a result of a breach of this Section 10.11, or which becomes available to the Administrative Agent, the Issuing Bank, any Lender or any Related Party of any of the foregoing on a non-confidential basis from a source other than the Borrower, (v) in connection with the exercise of any remedy hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, and (ix) subject to provisions substantially similar to this Section 10.11, to any actual or prospective assignee or Participant, or (vi) with the consent of the Borrower. Any Person required to maintain the confidentiality of any information as provided for in this Section 10.11 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such information as such Person would accord its own confidential information; provided that, in the case of clauses (ii) or (iii), with the exception of disclosure to bank regulatory authorities, the Administrative Agent, the Issuing Bank and each Lender agree, to the extent practicable and legally permissible, to give the Borrower prompt prior notice so that it may seek a protective order or other appropriate remedy.

Section 10.12. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which may be treated as interest on such Loan under applicable law (collectively, the “Charges”), shall exceed the maximum lawful rate of interest (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by a Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section 10.12 shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Rate to the date of repayment (to the extent permitted by applicable law), shall have been received by such Lender.

Section 10.13. Patriot Act. The Administrative Agent and each Lender to whom the Patriot Act applies hereby notifies the Loan Parties that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot 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 Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Patriot Act. The Borrower shall, and shall cause each of its Subsidiaries to, provide to the extent commercially reasonable, such information and take such other actions as are reasonably requested by the Administrative Agent or any Lender in order to assist the Administrative Agent and the Lenders in maintaining compliance with the Patriot Act.

Section 10.14. Location of Closing. Each Lender acknowledges and agrees that it has delivered, with the intent to be bound, its executed counterparts of this Agreement to Agent, c/o King & Spalding LLP, 0000 Xxxxxx xx xxx Xxxxxxxx, Xxx Xxxx, Xxx Xxxx 00000. Borrower acknowledges and agrees that it has delivered, with the intent to be bound, its executed counterparts of this Agreement and each other Loan Document, together with all other documents, instruments, opinions, certificates and other items required under Section 3.1, to Administrative Agent, c/o King & Spalding LLP, 0000 Xxxxxx xx xxx Xxxxxxxx, Xxx Xxxx, Xxx Xxxx 00000. All parties agree that closing of the transactions contemplated by this Credit Agreement has occurred in New York.

Section 10.15. Non-Recourse to the General Partner and Associated Persons. The Administrative Agent, the Issuing Bank and each Lender agrees on behalf of itself and its successors, assigns and legal representatives, that neither the General Partner nor any Person which is a partner, shareholder, member, owner, officer, director, supervisor, trustee or other principal (collectively, “Associated Persons”) of the Borrower, the General Partner, or any of their respective successors or assigns, shall have any personal liability for the payment or performance of any of the Borrower’s obligations hereunder or under any of the Notes and no monetary or other judgment shall be sought or enforced against the General Partner or any of such Associated Persons or any of their respective successors or assigns. Notwithstanding the foregoing, neither the Administrative Agent, the Issuing Bank nor any Lender shall be deemed barred by this Section 10.15 from asserting any claim against any Person based upon an allegation of fraud or misrepresentation.
