2.1 Commitment; Conversion to Term Loan. From and including the date of this Agreement and prior to the Revolving Credit Termination Date, upon the satisfaction of the conditions precedent set forth in Section 4.1 and 4.2, as applicable, each Lender severally agrees, on the terms and conditions set forth in this Agreement, to (i) make Revolving Loans to the Borrower from time to time and (ii) participate in Facility LCs and Swing Line Loans issued or made upon the request of the Borrower, in each case in an amount not to exceed in the aggregate at any one time outstanding of its Commitment; provided that at no time shall the Aggregate Outstanding Credit Exposure hereunder exceed the Aggregate Commitment. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow at any time prior to the Revolving Credit Termination Date. The commitment of each Lender to make any further Advances or further extensions of credit hereunder shall expire on the Revolving Credit Termination Date applicable to it. The LC Issuer will issue Facility LCs hereunder on the terms and conditions set forth in Section 2.20. If the Borrower so elects by delivery of a written notice to the Agent at least three (3), but not more than thirty (30), Business Days prior to the date of the then current Revolving Credit Termination Date, then on such Revolving Credit Termination Date (the “Loan Conversion Date”), (i) the Borrower’s option to borrow additional Loans and request additional Facility LCs shall terminate, (ii) the Commitments shall be terminated and (iii) the then outstanding aggregate principal amount of the Loans shall be converted to a term loan which shall, in the case of each Lender, be in the aggregate amount of such Lender’s outstanding Loans on such date, and which shall be due and payable in full, together with accrued interest and all other Obligations, on the first anniversary of the Loan Conversion Date, with any prepayment thereof to be made subject to Section 2.7 and Section 3.4; provided, that no such conversion shall occur if a Default or Unmatured Default has occurred and is continuing either on the date of delivery of such notice or on the Loan Conversion Date. Amounts repaid or prepaid on or after the Loan Conversion Date may not be reborrowed. If a term loan conversion has not previously been elected or completed in accordance with the terms hereof, then on the Revolving Credit Termination Date then in effect, the Commitments shall be terminated and all of the Loans and other Obligations shall be due and payable in full. For the avoidance of doubt, it is hereby agreed that the Borrower shall not have the option to convert the Loans of any Non-Extending Lender to a term loan on

the Revolving Commitment Termination Date for such Non-Extending Lender (to the extent such Revolving Commitment Termination Date has been extended for any other Lender) and shall be required to repay such Loans in accordance with Section 2.2.

2.2 Required Payments; Termination. Any outstanding Advances and all other unpaid Obligations shall be paid in full by the Borrower on the Facility Termination Date. Notwithstanding the termination of this Agreement on the Facility Termination Date, until all of the Obligations (other than contingent indemnity obligations) shall have been fully paid and satisfied and all financing arrangements among the Borrower and the Lenders hereunder and under the other Loan Documents shall have been terminated, all of the rights and remedies under this Agreement and the other Loan Documents shall survive. In addition, the Borrower shall make all payments required under Section 2.21 to each Lender that does not consent to the extension of the Revolving Credit Termination Date.

2.3 Ratable Loans. Each Advance hereunder (other than any Swing Line Loan) shall consist of Loans made from the several Lenders ratably in proportion to the ratio that their respective Commitments bear to the Aggregate Commitment.

2.4 Types of Advances. The Advances (other than any Swing Line Loan) may be Floating Rate Advances or Eurodollar Advances, or a combination thereof, selected by the Borrower in accordance with Sections 2.8 and 2.9. The Borrower may request Swing Line Loans in accordance with Section 2.23.

2.5.2 Utilization Fee. For any period (including after the Loan Conversion Date) during which the Aggregate Outstanding Credit Exposure of all the Lenders hereunder exceeds fifty percent (50%) of the Aggregate Commitment hereunder (which, after the Commitments have been terminated, shall be based on the Aggregate Commitment immediately prior to such termination) then in effect on such date, the Borrower will pay to the Agent for the ratable benefit of the Lenders a utilization fee (the “Utilization Fee”) at a per annum rate equal to the Applicable Fee Rate on the average daily Aggregate Outstanding Credit Exposure during such period. The Utilization Fee shall be payable quarterly in arrears on each Fee Payment Date and on the Specified Date.

2.5.3 Reductions in Aggregate Commitment. The Borrower may permanently reduce the Aggregate Commitment in whole, or in part, ratably among the Lenders in integral multiples of $5,000,000, upon at least two (2) Business Days’ written notice to the Agent, which notice shall specify the amount of any such reduction; provided,however , that the amount of the Aggregate Commitment may not be reduced below the aggregate principal amount of the outstanding Advances, after taking into account any prepayments to be made on or before such date. If the Aggregate Commitment is reduced to zero, the Revolving Credit Termination Date shall have been deemed to occur.

2.6 Minimum Amount of Each Advance. Each Eurodollar Advance shall be in the minimum amount of $1,000,000 (and in multiples of $1,000,000 if in excess thereof), and each Floating Rate Advance (other than Swing Line Loans (which are subject to Section 2.23) or an Advance to repay Swing Line Loans) shall be in the minimum amount of $1,000,000 (and in multiples of $1,000,000 if in excess thereof); provided,however , that any Floating Rate Advance may be in the amount of the unused Aggregate Commitment.

2.7 Optional Principal Payments. The Borrower may from time to time pay, without penalty or premium, all outstanding Floating Rate Advances or any portion thereof in a minimum aggregate amount of $1,000,000 or any integral multiple of $1,000,000 in excess thereof (other than in the case of Swing Line Loans) on any Business Day upon notice to the Agent by no later than 11:00 a.m. (Charlotte, North Carolina time) on the date of such prepayment. The Borrower may at any time pay, without penalty or premium, all outstanding Swing Line Loans or any portion thereof in a minimum amount of $100,000 and increments of $100,000 in excess thereof on any Business Day upon notice to the Agent and the Swing Line Lender by 11:00 a.m. (Charlotte, North Carolina time) on the date of such repayment. The Borrower may from time to time pay, subject to the payment of any funding indemnification amounts required by Section 3.4 but without penalty or premium, all outstanding Eurodollar Advances, or any portion thereof in a minimum aggregate amount of $1,000,000 or any integral multiple of $1,000,000 in excess thereof upon three (3) Business Days’ prior notice to the Agent. Revolving Loans and Swing Line Loans which are prepaid may, subject to the other terms and conditions of this Agreement, be reborrowed.

2.8 Method of Selecting Types and Interest Periods for New Advances (other than Swing Line Loans). The Borrower shall select the Type of Advance (other than any Swing Line Loan which is subject to Section 2.23) and, in the case of each Eurodollar Advance, the Interest Period applicable thereto from time to time. The Borrower shall give the Agent irrevocable notice (a “Borrowing Notice”) not later than 11:00 a.m. (Charlotte, North Carolina time) on the Borrowing Date of each Floating Rate Advance and three (3) Business Days before the Borrowing Date for each Eurodollar Advance, specifying:

2.8.1

the Borrowing Date, which shall be a Business Day, of such Advance,

2.8.2

the aggregate amount of such Advance,

2.8.3

the Type of Advance selected, and

2.8.4

in the case of each Eurodollar Advance, the Interest Period applicable thereto.

Not later than noon (Charlotte, North Carolina time) on each Borrowing Date, each Lender shall make available its Revolving Loan or Revolving Loans in funds immediately available in Charlotte, North Carolina to the Agent at its address specified pursuant to Article XIII. The Agent will promptly make the funds so received from the Lenders available to the Borrower at the Agent’s aforesaid address.

2.9 Conversion and Continuation of Outstanding Advances. Floating Rate Advances shall continue as Floating Rate Advances unless and until such Floating Rate Advances are converted into Eurodollar Advances pursuant to this Section 2.9 or are repaid in accordance with Section 2.7. Each Eurodollar Advance shall continue as a Eurodollar Advance until the end of the then applicable Interest Period therefor, at which time such Eurodollar Advance shall be automatically converted into a Floating Rate Advance unless (x) such Eurodollar Advance is or was repaid in accordance with Section 2.7 or (y) the Borrower shall have given the Agent a Conversion/Continuation Notice (as defined below) requesting that, at the end of such Interest Period, such Eurodollar Advance continue as a Eurodollar Advance for the

same or another Interest Period. Subject to the terms of Section 2.6, the Borrower may elect from time to time to convert all or any part of a Floating Rate Advance into a Eurodollar Advance. The Borrower shall give the Agent irrevocable notice (a “Conversion/Continuation Notice”) of each conversion of a Floating Rate Advance into a Eurodollar Advance or continuation of a Eurodollar Advance not later than 11:00 a.m. (Charlotte, North Carolina time) on the third Business Day prior to the date of the requested conversion or continuation, specifying:

2.9.1 the requested date, which shall be a Business Day, of such conversion or continuation,

2.9.2 the aggregate amount and Type of the Advance which is to be converted or continued,

and

2.9.3 the duration of the Interest Period applicable thereto.

Notwithstanding anything to the contrary in this Agreement, no Swing Line Loan may be converted from a Floating Rate Advance to a Eurodollar Advance.

2.10 Changes in Interest Rate, etc. Each Floating Rate Advance shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Advance is made or is automatically converted from a Eurodollar Advance into a Floating Rate Advance pursuant to Section 2.9, to but excluding the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.9 hereof, at a rate per annum equal to the Floating Rate for such day. Each Swing Line Loan shall bear interest on the outstanding principal amount thereof, for each day from and including the day such Swing Line Loan is made to but excluding the date it is paid, at a rate per annum equal to the Swing Line Rate for such day. Changes in the rate of interest on that portion of any Advance maintained as a Floating Rate Advance or on a Swing Line Loan will take effect simultaneously with each change in the Alternate Base Rate or LIBOR Market Index Rate, as applicable. Each Eurodollar Advance shall bear interest on the outstanding principal amount thereof from and including the first day of the Interest Period applicable thereto to (but not including) the last day of such Interest Period at the interest rate determined by the Agent as applicable to such Eurodollar Advance based upon the Borrower’s selections under Sections 2.8 and 2.9 and otherwise in accordance with the terms hereof. No Interest Period may end after the Facility Termination Date. The Borrower shall select Interest Periods so that it is not necessary to repay any portion of a Eurodollar Advance prior to the last day of the applicable Interest Period in order to make a mandatory prepayment required pursuant to Section 2.2.

2.11 Rates Applicable After Default. Notwithstanding anything to the contrary contained in Section 2.8, 2.9 or 2.10, during the continuance of a Default or Unmatured Default the Required Lenders may, at their option, by notice to the Borrower, declare that no Advance may be made as, converted into or continued as a Eurodollar Advance. During the continuance of a Default the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 8.2 requiring unanimous consent of the Lenders to changes in interest rates), declare that (i) each Eurodollar Advance shall bear interest (after, as well as before judgment) for the remainder of the applicable Interest Period (and for each subsequent Interest Period during the continuance of such Default or Unmatured Default) if the Required Lenders have not prohibited Eurodollar Advances) at the rate otherwise applicable to such Interest Period plus 2% per annum, (ii) each Floating Rate Advance shall bear interest (after, as well as before judgment) at a rate per annum equal to the Floating Rate in effect from time to time plus 2% per annum, (iii) each Swing Line Loan shall bear interest (after, as well as before judgment) at a rate per annum equal to the Swing Line Rate in effect from time to time plus 2% per annum, (iv) the LC Fee shall be increased by 2% per annum and (v) all outstanding and past due fees hereunder which do not otherwise bear interest shall accrue

interest (after, as well as before judgment) at a rate per annum equal to the Floating Rate in effect from time to time plus 2% per annum; provided that, during the continuance of a Default under Section 7.6 or 7.7, the interest rates set forth in clauses (i), (ii) and (iii) above and the increase in the LC Fee set forth in clause (iv) above shall be applicable to all Advances without any election or action on the part of the Agent or any Lender.

2.12 Method of Payment. All payments of the Obligations hereunder shall be made, without setoff, deduction, or counterclaim, in immediately available funds to the Agent at the Agent’s address specified pursuant to Article XIII, or at any other Lending Installation of the Agent specified in writing by the Agent to the Borrower, by noon (Charlotte, North Carolina time) on the date when due and shall be applied ratably (except in the case of (i) Reimbursement Obligations for which the LC Issuer has not been fully indemnified by the Lenders, (ii) Swing Line Loans or (iii) as otherwise specifically required hereunder) by the Agent among the Lenders. Each payment delivered to the Agent for the account of any Lender shall be delivered promptly by the Agent to such Lender in the same type of funds that the Agent received at its address specified pursuant to Article XIII or at any Lending Installation specified in a notice received by the Agent from such Lender. The Agent is hereby authorized to charge the account of the Borrower maintained with Wachovia for each payment of principal, interest and fees as it becomes due hereunder. Each reference to the Agent in this Section 2.12 shall also be deemed to refer, and shall apply equally, to (x) the LC Issuer in the case of payments required to be made by the Borrower to the LC Issuer pursuant to Section 2.20.6 and (y) the Swing Line Lender in the case of payments required to be made by the Borrower to the Swing Line Lender pursuant to Section 2.23.4.

2.13 Noteless Agreement; Evidence of Indebtedness. (i) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(ii) The Agent shall also maintain accounts in which it will record (a) the amount of each Loan made hereunder, the Type thereof and the Interest Period (in the case of a Eurodollar Advance) with respect thereto, (b) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder, (c) the original stated amount of each Facility LC and the amount of LC Obligations outstanding at any time, and (d) the amount of any sum received by the Agent hereunder from the Borrower and each Lender’s share thereof.

(iii) The entries maintained in the accounts maintained pursuant to paragraphs (i) and (ii) above shall be prima facie evidence of the existence and amounts of the Obligations therein recorded absent manifest error; provided,however , that the failure of the Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

(iv) Any Lender may request that its Loans be evidenced by a promissory note, or in the case of the Swing Line Lender, promissory notes representing its Revolving Loans and Swing Line Loans, respectively, in substantially the form of Exhibit E with applicable changes for notes evidencing Swing Line Loans (a “Note”). In such event, the Borrower shall prepare, execute and deliver to such Lender such Note payable to the order of such Lender. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (prior to any assignment pursuant to Section 12.3) be represented by one or more Notes payable to the order of the payee named therein, except to the extent that any such Lender subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in paragraphs (i) and (ii) above.

2.14 Telephonic Notices. The Borrower hereby authorizes the Lenders and the Agent to extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds based on telephonic notices made by any person or persons the Agent or any Lender in good faith believes to be acting on behalf of the Borrower, it being understood that the foregoing authorization is specifically intended to allow Borrowing Notices, Swing Line Borrowing Notices and Conversion/Continuation Notices to be given telephonically. The Borrower agrees to deliver promptly to the Agent a written confirmation, if such confirmation is requested by the Agent or any Lender, of each telephonic notice, signed by a Designated Person. If the written confirmation differs in any material respect from the action taken by the Agent and the Lenders, the records of the Agent and the Lenders shall govern absent manifest error.

2.15 Interest Payment Dates; Interest and Fee Basis. Interest accrued on each Floating Rate Advance and Swing Line Loan shall be payable in arrears on each Payment Date, commencing with the first such date to occur after the date hereof, on any date on which the Floating Rate Advance or Swing Line Loan is prepaid, whether due to acceleration or otherwise, and at maturity. Interest accrued on that portion of the outstanding principal amount of any Floating Rate Advance converted into a Eurodollar Advance on a day other than a Payment Date shall be payable on the date of conversion. Interest accrued on each Eurodollar Advance shall be payable on the last day of its applicable Interest Period, on any date on which the Eurodollar Advance is prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period. Interest accrued pursuant to Section 2.11 shall be payable on demand. Interest on Eurodollar Advances, Swing Line Loans (other than Swingline Loans that are Floating Rate Advances), LC Fees and all other fees shall be calculated for actual days elapsed on the basis of a 360-day year. Interest on Floating Rate Advances shall be calculated for actual days elapsed on the basis of a 365, or when appropriate 366, day year. Interest shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if payment is received prior to noon (Charlotte, North Carolina time) at the place of payment. If any payment of principal of or interest on an Advance, any fees or any other amounts payable to the Agent or any Lender hereunder shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest and fees in connection with such payment.

2.16 Notification of Advances, Interest Rates, Prepayments and Commitment Reductions; Availability of Loans. Promptly after receipt thereof, the Agent will notify each Lender of the contents of each Aggregate Commitment reduction notice, Borrowing Notice, Swing Line Borrowing Notice, Conversion/Continuation Notice, and repayment notice received by it hereunder. The LC Issuer shall notify the Agent promptly after the issuance of a Facility LC, and the Agent will notify each Lender of such issuance. The Agent will notify the Borrower and each Lender of the interest rate applicable to each Eurodollar Advance promptly upon determination of such interest rate and will give the Borrower and each Lender prompt notice of each change in the Alternate Base Rate.

2.17 Lending Installations. Subject to Section 3.7, each Lender may book its Loans and its participation in any LC Obligations and Swing Line Loans and the LC Issuer may book the Facility LCs at any Lending Installation selected by such Lender or the LC Issuer, as applicable, and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Loans, Facility LCs, participations in LC Obligations and Swing Line Loans and any Notes issued hereunder shall be deemed held by each Lender or the LC Issuer, as applicable, for the benefit of any such Lending Installation. Each Lender and the LC Issuer may, by written notice to the Agent and the Borrower in accordance with Article XIII, designate replacement or additional Lending

Installations through which Loans will be made by it or Facility LCs will be issued by it and for whose account Loan payments or payments with respect to Facility LCs are to be made.

2.18 Non-Receipt of Funds by the Agent. Unless the Borrower or a Lender, as the case may be, notifies the Agent prior to the date on which it is scheduled to make payment to the Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal, interest or fees to the Agent for the account of the Lenders, that it does not intend to make such payment, the Agent may assume that such payment has been made. The Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If such Lender or the Borrower, as the case may be, has not in fact made such payment to the Agent, the recipient of such payment shall, on demand by the Agent, repay to the Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate per annum equal to (x) in the case of payment by a Lender, the Federal Funds Effective Rate for such day for the first three days and, thereafter, the interest rate applicable to the relevant Loan or (y) in the case of payment by the Borrower, the interest rate applicable to the relevant Loan.

2.19 Replacement of Lender. If the Borrower is required pursuant to Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender or if any Lender’s obligation to make or continue, or to convert Floating Rate Advances into, Eurodollar Advances shall be suspended pursuant to Section 3.3 or, if and for so long as (and solely with respect to) any Lender is a Defaulting Lender (in each of the foregoing cases, such affected Lender being an “Affected Lender”), the Borrower may elect, if such amounts continue to be charged, such suspension is still effective or such Lender continues to be a Defaulting Lender, to replace such Affected Lender as a Lender party to this Agreement; provided that no Default or Unmatured Default shall have occurred and be continuing at the time of such replacement, and provided further that, concurrently with such replacement, (i) another bank or other entity which is reasonably satisfactory to the Borrower and the Agent shall agree, as of such date, to purchase for cash the Loans due to the Affected Lender pursuant to an assignment substantially in the form of Exhibit C and to become a Lender for all purposes under this Agreement and to assume all obligations of the Affected Lender to be terminated as of such date and to comply with the requirements of Section 12.3 applicable to assignments, and (ii) the Borrower shall pay to such Affected Lender in same day funds on the day of such replacement (A) all interest, fees and other amounts then accrued but unpaid to such Affected Lender by the Borrower hereunder to and including the date of termination, including without limitation payments due to such Affected Lender under Sections 3.1, 3.2 and 3.5, and (B) other than with respect to the replacement of a Defaulting Lender, an amount, if any, equal to the payment which would have been due to such Lender on the day of such replacement under Section 3.4 had the Loans of such Affected Lender been prepaid on such date rather than sold to the replacement Lender, in each case to the extent not paid by the purchasing lender.

2.20

Facility LCs.

2.20.1 Issuance. The LC Issuer hereby agrees, on the terms and conditions set forth in this Agreement, to issue standby and commercial letters of credit (each such letter of credit, a “Facility LC”) and to renew, extend, increase, decrease or otherwise modify each Facility LC (“Modify,” and each such action, a “Modification”), from time to time from and including the date of this Agreement and prior to the Revolving Credit Termination Date upon the request of the Borrower; providedthat immediately after each such Facility LC is issued or Modified, the Aggregate Outstanding Credit Exposure shall not exceed the Aggregate Commitment. No Facility LC shall have an expiry date later than the earlier of (x) one year after the Revolving Credit Termination Date and (y) one year after its issuance; provided that any Facility LC with a one-year tenor may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in the preceding clause (x)). If one or more

Facility LC’s are outstanding on the Revolving Commitment Termination Date, the Borrower shall pay to the LC Issuer cash, to be held by the LC Issuer, for the benefit of the Lenders, in the Facility LC Collateral Account as security for the LC Obligations in respect of subsequent drawings under all then outstanding Facility LC’s in an amount equal to 100% of the maximum aggregate amount which may be drawn under all Facility LC’s then outstanding (which cash will be invested pursuant to the requirements of Section 2.20.11), pursuant to documentation in form and substance reasonably satisfactory to the Agent.If any Facility LC contains a provision pursuant to which it is deemed to be automatically renewed unless notice of termination is given by the LC Issuer with respect to such Facility LC, the LC Issuer shall timely give notice of termination if (i) as of the close of business on the seventeenth (17^th) day prior to the last day upon which the LC Issuer’s notice of termination may be given to the beneficiaries of such Facility LC, the LC Issuer has received a notice of termination from the Borrower or a notice from the Agent that the conditions to issuance of such Facility LC have not been satisfied or (ii) the renewed Facility LC would extend beyond the date referred to in clause (x) above.

2.20.2 Participations. Upon (a) the issuance by the LC Issuer of each Facility LC in accordance with this Section 2.20 and (b) the Modification of each Facility LC increasing the face amount thereof in accordance with this Section 2.20, the LC Issuer shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably sold to each Lender, and each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from the LC Issuer, a participation in such Facility LC (and each Modification increasing the amount thereof) and the related LC Obligations in proportion to its Pro Rata Share.

2.20.3 Notice. Subject to Section 2.20.1, the Borrower shall give the LC Issuer notice prior to 11:00 a.m. (Charlotte, North Carolina time) at least five (5) Business Days prior to the proposed date of issuance or Modification of each Facility LC, specifying the beneficiary, the proposed date of issuance (or Modification) and the expiry date of such Facility LC, and describing the proposed terms of such Facility LC and the nature of the transactions proposed to be supported thereby. The LC Issuer shall promptly notify the Agent and shall provide the Agent with a copy of any letter of credit application or modification or other written evidence of the Facility LC as requested, and, upon issuance only, the Agent shall promptly notify each Lender, of the contents thereof and of the amount of such Lender’s participation in such Facility LC. The issuance or Modification by the LC Issuer of any Facility LC shall, in addition to the conditions precedent set forth in Article IV (the satisfaction of which the LC Issuer shall have no duty to ascertain), be subject to the conditions precedent that such Facility LC shall be satisfactory to the LC Issuer and that the Borrower shall have executed and delivered such application agreement and/or such other instruments and agreements relating to such Facility LC as the LC Issuer shall have reasonably requested (each, a “Facility LC Application”). In the event of any conflict between the terms of this Agreement and the terms of any Facility LC Application, the terms of this Agreement shall control.

2.20.4 LC Fees. The Borrower shall pay to the Agent, for the account of the Lenders ratably in accordance with their respective Pro Rata Shares, (i) with respect to each standby Facility LC, a letter of credit fee at a per annum rate equal to the Applicable Margin for Eurodollar Loans in effect from time to time on the average daily undrawn stated amount under such standby Facility LC, such fee to be payable in arrears on each Fee Payment Date, and (ii) with respect to each commercial Facility LC, a letter of credit fee at a per annum rate equal to 0.20% on the average daily undrawn stated amount under such commercial Facility LC (or, with respect to a Modification of any such commercial Facility LC which increases the stated amount thereof, such increase in the stated amount), such fee to be payable upon demand on the date the LC Issuer shall make payment on such commercial Facility LC. The Borrower shall also pay to the LC Issuer for its own account (x) a fronting fee at a per annum rate equal to 0.125% on the average daily undrawn stated amount under each standby Facility LC, such fee to be payable in arrears on each Fee Payment Date, and (y) documentary and processing charges in connection

with the issuance or Modification of and draws under Facility LCs in accordance with the LC Issuer’s standard schedule for such charges as in effect from time to time. Each fee described in this Section 2.20.4 shall constitute an “LC Fee”.

2.20.5 Administration; Reimbursement by Lenders. Upon receipt from the beneficiary of any Facility LC of any demand for payment under such Facility LC, the LC Issuer shall notify the Agent and the Agent shall promptly notify the Borrower and each other Lender as to the amount to be paid by the LC Issuer as a result of such demand and the proposed payment date (the “LC Payment Date”). The responsibility of the LC Issuer to the Borrower and each Lender shall be only to determine that the documents (including each demand for payment) delivered under each Facility LC in connection with such presentment shall be in conformity in all material respects with such Facility LC. The LC Issuer shall endeavor to exercise the same care in the issuance and administration of the Facility LCs as it does with respect to letters of credit in which no participations are granted, it being understood that in the absence of any gross negligence or willful misconduct by the LC Issuer, each Lender shall be unconditionally and irrevocably liable without regard to the occurrence of any Default or any condition precedent whatsoever, to reimburse the LC Issuer on demand for (i) such Lender’s Pro Rata Share of the amount of each payment made by the LC Issuer under each Facility LC to the extent such amount is not reimbursed by the Borrower pursuant to Section 2.20.6 below, plus (ii) interest on the foregoing amount to be reimbursed by such Lender, for each day from the date of the LC Issuer’s demand for such reimbursement (or, if such demand is made after 11:00 a.m. (Charlotte, North Carolina time) on such date, from the next succeeding Business Day) to the date on which such Lender pays the amount to be reimbursed by it, at a rate of interest per annum equal to the Federal Funds Effective Rate for the first three days and, thereafter, at a rate of interest equal to the rate applicable to Floating Rate Advances.

2.20.6 Reimbursement by Borrower. The Borrower shall be irrevocably and unconditionally obligated to reimburse the LC Issuer on or before the applicable LC Payment Date for any amounts to be paid by the LC Issuer upon any drawing under any Facility LC, without presentment, demand, protest or other formalities of any kind; provided that neither the Borrower nor any Lender shall hereby be precluded from asserting any claim for direct (but not consequential) damages suffered by the Borrower or such Lender to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of the LC Issuer in determining whether a request presented under any Facility LC issued by it complied with the terms of such Facility LC or (ii) the LC Issuer’s failure to pay under any Facility LC issued by it after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. All such amounts paid by the LC Issuer and remaining unpaid by the Borrower shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the rate applicable to Floating Rate Advances, including any increase thereof pursuant to Section 2.11, from and after the applicable LC Payment Date. The LC Issuer will pay to each Lender ratably in accordance with its Pro Rata Share all amounts received by it from the Borrower for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Facility LC issued by the LC Issuer, but only to the extent such Lender has made payment to the LC Issuer in respect of such Facility LC pursuant to Section 2.20.5. Subject to the terms and conditions of this Agreement (including, without limitation, the submission of a Borrowing Notice in compliance with Section 2.8 and the satisfaction of the applicable conditions precedent set forth in Article IV), the Borrower may request an Advance hereunder for the purpose of satisfying any Reimbursement Obligation.

2.20.7 Obligations Absolute. The Borrower’s obligations under this Section 2.20 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the Borrower may have or have had against the LC Issuer, any Lender or any beneficiary of a Facility LC. The Borrower further agrees with the LC Issuer and the Lenders that the LC Issuer and the Lenders shall not be responsible for, and the Borrower’s Reimbursement Obligation in respect of any Facility LC shall not be affected by, among other things, the

validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among the Borrower, any of its Affiliates, the beneficiary of any Facility LC or any financing institution or other party to whom any Facility LC may be transferred or any claims or defenses whatsoever of the Borrower or of any of its Affiliates against the beneficiary of any Facility LC or any such transferee. The LC Issuer shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Facility LC. The Borrower agrees that any action taken or omitted by the LC Issuer or any Lender under or in connection with each Facility LC and the related drafts and documents, if done without gross negligence or willful misconduct, shall be binding upon the Borrower and shall not put the LC Issuer or any Lender under any liability to the Borrower. Nothing in this Section 2.20.7 is intended to limit the right of the Borrower to make a claim against the LC Issuer for damages as contemplated by the proviso to the first sentence of Section 2.20.6.

2.20.8 Actions of LC Issuer. The LC Issuer shall be entitled to rely, and shall be fully protected in relying, upon any Facility LC, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document reasonably believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by the LC Issuer. In the absence of (x) willful misconduct or gross negligence of the LC Issuer in determining whether a request presented under any Facility LC complied with the terms of such Facility LC or (y) the LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC, the LC Issuer shall be fully (i) justified in failing or refusing to take any action under this Agreement unless it shall first have received such advice or concurrence of the Required Lenders as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action, and (ii) protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Required Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Lenders and any future holders of a participation in any Facility LC.

2.20.9 Indemnification. The Borrower hereby agrees to indemnify and hold harmless each Lender, the LC Issuer and the Agent, and their respective directors, officers, agents and employees from and against any and all claims and damages, losses, liabilities, costs or expenses which such Lender, the LC Issuer or the Agent may incur (or which may be claimed against such Lender, the LC Issuer or the Agent by any Person whatsoever) by reason of or in connection with the issuance, execution and delivery or transfer of or payment or failure to pay under any Facility LC or any actual or proposed use of any Facility LC, including, without limitation, any claims, damages, losses, liabilities, costs or expenses which the LC Issuer may incur by reason of or on account of the LC Issuer issuing any Facility LC which specifies that the term “Beneficiary” included therein includes any successor by operation of law of the named Beneficiary, but which Facility LC does not require that any drawing by any such successor Beneficiary be accompanied by a copy of a legal document, satisfactory to the LC Issuer, evidencing the appointment of such successor Beneficiary; provided that the Borrower shall not be required to indemnify any Lender, the LC Issuer or the Agent for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (x) the willful misconduct or gross negligence of the LC Issuer in determining whether a request presented under any Facility LC complied with the terms of such Facility LC, (y) the LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC, or (z) the failure of any Lender to fulfill or comply with its obligations to the LC Issuer hereunder.

2.20.10 Lenders’ Indemnification. Each Lender shall, ratably in accordance with its Pro Rata Share (determined at the time such indemnity is sought), indemnify the LC Issuer, its affiliates

and their respective directors, officers, agents and employees (to the extent not reimbursed by the Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct or the LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of the Facility LC) that any such indemnitees may suffer or incur in connection with this Section 2.20 or any action taken or omitted by such indemnitees hereunder.

2.20.11 Facility LC Collateral Account. The Borrower agrees that it will, upon the request of the Agent or the Required Lenders and until the final expiration date of any Facility LC and thereafter as long as any amount is payable to the LC Issuer or the Lenders in respect of any Facility LC, maintain a special collateral account pursuant to arrangements reasonably satisfactory to the Agent (the “Facility LC Collateral Account”) at the Agent’s office at the address specified pursuant to Article XIII, in the name of such Borrower but under the sole dominion and control of the Agent, for the benefit of the Lenders and in which such Borrower shall have no interest other than as set forth in Section 2.20.1 and Section 8.1. The Borrower hereby pledges, assigns and grants to the Agent, on behalf of and for the ratable benefit of the Lenders (including the LC Issuer), a security interest in all of the Borrower’s right, title and interest in and to all funds which may from time to time be on deposit in the Facility LC Collateral Account to secure the prompt and complete payment and performance of the Obligations. The Agent will invest any funds on deposit from time to time in the Facility LC Collateral Account in certificates of deposit of Wachovia, or of any other Lender selected by the Agent, having a maturity not exceeding thirty (30) days. Nothing in this Section 2.20.11 shall either obligate the Agent to require the Borrower to deposit any funds in the Facility LC Collateral Account or limit the right of the Agent to release any funds held in the Facility LC Collateral Account in each case other than as required by Section 2.20.1 or Section 8.1.

2.20.12 Rights as a Lender. In its capacity as a Lender, the LC Issuer shall have the same rights and obligations as any other Lender.

2.21 Extension of Revolving Credit Termination Date. No earlier than sixty (60) days and no later than thirty (30) days prior to each anniversary of the Closing Date, the Borrower shall have the option to request an extension of the Revolving Credit Termination Date for an additional one-year period. Any election by a Lender to extend its Commitment will be at such Lender’s sole discretion. Each Lender shall, by notice to the Agent given not later than the date (the “Notice Date”) that is 15 days prior to the applicable anniversary of the Closing Date, advise the Agent whether or not such Lender agrees to such extension (and each Lender that determines not to so extend its Revolving Credit Termination Date (a “Non-Extending Lender”) shall notify the Agent of such fact promptly after such determination (but in any event no later than the Notice Date) and any Lender that does not so advise the Agent on or before the Notice Date shall be deemed to be a Non-Extending Lender. Subject to the Agent’s receipt of written consents to such extension from at least the Required Lenders on or prior to the Notice Date, and so long as no Default or Unmatured Default has occurred and is continuing, the Revolving Credit Termination Date shall be extended for an additional one-year period for each consenting Lender; provided that each Non-Extending Lender shall be required only to complete its Commitment up to the previously effective Revolving Credit Termination Date (without giving effect to such extension). All Obligations and other amounts payable hereunder to such Non-Extending Lender shall become due and payable by the Borrower on the previously effective Revolving Credit Termination Date (without giving effect to such extension) and the Aggregate Commitment shall be reduced by the total Commitments of all Non-Extending Lenders expiring on such previously effective Revolving Credit Termination Date (without giving effect to such extension) unless one or more lenders (including other Lenders) shall have agreed to assume or increase a Commitment hereunder. Each Non-Extending Lender shall be required to maintain

its original Commitment up to the previously effective Revolving Credit Termination Date (without giving effect to such extension) that such Non-Extending Lender had previously agreed upon.

The Borrower shall have the right on or before 45 days after the applicable anniversary of the Closing Date to replace each Non-Extending Lender with one or more institutions (each, an “Additional Commitment Lender”) (a) that are existing Lenders (and, if any such Additional Commitment Lender is already a Lender, its Commitment shall be in addition to such Lender’s Commitment hereunder on such date) or (b) that are not existing Lenders; provided that any such institution (i) must be acceptable to the Administrative Agent (which approval shall not be unreasonably withheld or delayed), (ii) must meet the requirements set forth in Section 12.3.1 and (iii) must become a Lender for all purposes under this Agreement by execution and delivery of an appropriate joinder agreement in a manner acceptable to the Borrower and the Administrative Agent.

2.22

Increase of Aggregate Commitment.

2.22.1 At any time prior to the Revolving Credit Termination Date, the Borrower shall have the ability, in consultation with the Agent (and without the consent of any non-increasing Lender), to request increases in the Aggregate Commitment; provided that (A) no Lender shall have any obligation to increase its Commitment, (B) the Borrower shall only be permitted to request such an increase on five (5) separate occasions, (C) each such requested increase shall be in a minimum principal amount of $50,000,000 or, if less, the remaining amount permitted pursuant to clause (D) below, (D) in no event shall the aggregate amount of all such increases exceed $250,000,000, (E) no Default or Unmatured Default shall have occurred and be continuing or would result from the proposed increase and (F) the Borrower shall have obtained all necessary corporate authorizations and governmental approvals in order to effect such increase.

2.22.2 The Agent shall promptly give notice of such requested increase to the Lenders. Each Lender shall notify the Agent within ten (10) Business Days (or such longer period of time which may be agreed upon by the Agent and the Borrower and communicated to the Lenders) from the date of delivery of such notice to the Lenders whether or not it agrees to increase its Commitment and, if so, by what amount. Any Lender not responding within such time period shall be deemed to have declined to increase its Commitment. The Agent shall notify the Borrower of the Lenders’ responses to each request made hereunder. The Borrower may also invite additional Purchasers which meet the requirements set forth in Section 12.3.1 to become Lenders pursuant to a joinder agreement in the form attached hereto as Exhibit F.

2.22.3 The Aggregate Outstanding Credit Exposure will be reallocated on the effective date of such increase among the Lenders in accordance with their revised Pro Rata Shares (and the Lenders agree to make all payments and adjustments necessary to effect the reallocation and the Borrower shall pay any and all costs required pursuant to Section 3.4 in connection with such reallocation as if such reallocation were a repayment).

2.23

Swing Line Loans.

2.23.1 Amount of Swing Line Loans. Upon the satisfaction of the conditions precedent set forth in Section 4.2 and, if such Swing Line Loan is to be made on the date of the initial Advance hereunder, the satisfaction of the conditions precedent set forth in Section 4.1 as well, from and including the date of this Agreement and prior to the Revolving Credit Termination Date, the Swing Line Lender may, in its sole discretion and on the terms and conditions set forth in this Agreement, make Swing Line Loans to the Borrower from time to time in an aggregate principal amount not to exceed the Swing Line Limit, provided that Swing Line Loans may be made even if the aggregate principal amount

of Swing Line Loans outstanding at any time, when added to the aggregate principal amount of Revolving Loans made by the Swing Line Lender in its capacity as a Lender at such time and its LC Obligations at such time, would exceed the Swing Line Lender’s own Commitment as a Lender at such time and provided further that at no time shall (a) the Aggregate Outstanding Credit Exposure at any time exceed the Aggregate Commitment or (b) the sum of (i) the Swing Line Lender’s Pro Rata Share of the Swing Line Loans, plus (ii) the outstanding Revolving Loans made by the Swing Line Lender pursuant to Section 2.1, plus (iii) an amount equal to the Swing Line Lender’s ratable obligation to purchase participations in the LC Obligations at such time, exceed the Swing Line Lender’s Commitment at such time. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow Swing Line Loans at any time prior to the Revolving Credit Termination Date. Subject to the terms and conditions of this Agreement (including, without limitation, the submission of a Borrowing Notice in compliance with Section 2.8 and the satisfaction of the applicable conditions precedent set forth in Article IV), the Borrower may request an Advance (other than a Swing Line Loan) hereunder for the purpose of repaying any Swing Line Loan.

2.23.2 Borrowing Notice. The Borrower shall deliver to the Agent and the Swing Line Lender irrevocable notice (a “Swing Line Borrowing Notice”) not later than noon (Charlotte, North Carolina time) on the Borrowing Date of each Swing Line Loan, specifying (i) the applicable Borrowing Date (which date shall be a Business Day), (ii) the aggregate amount of the requested Swing Line Loan which shall be an amount not less than $500,000 and in an integral multiple of $100,000 in excess thereof and (iii) the desired Swing Line Rate for such Swing Line Loan. The Swing Line Lender shall give prompt notice, but in any event not later than 1:00 p.m. (Charlotte, North Carolina time) to the Borrower and the Agent in the event that the Swing Line Lender declines to make such Swing Line Loan (a “Decline Notice”); it being understood that the failure of the Swing Line Lender to provide a Decline Notice in a timely manner shall be deemed the consent of the Swing Line Lender to provide such Swing Line Loan in accordance with the terms of this Agreement. The Swing Line Loans shall bear interest at the Swing Line Rate set forth in the Swing Line Borrowing Notice.

2.23.3 Making of Swing Line Loans. Promptly after receipt of a Swing Line Borrowing Notice, provided that the Agent has not received a Decline Notice from the Swing Line Lender in respect thereof, the Agent shall notify each Lender by fax, or other similar form of transmission, of the requested Swing Line Loan. Not later than 2:00 p.m. (Charlotte, North Carolina time) on the applicable Borrowing Date, the Swing Line Lender shall make available the Swing Line Loan, in funds immediately available in Charlotte, North Carolina, to the Agent at its address specified pursuant to Article XIII. The Agent will promptly make the funds so received from the Swing Line Lender available to the Borrower on the Borrowing Date at the Agent’s aforesaid address.

2.23.4 Repayment of Swing Line Loans. Each Swing Line Loan shall be paid in full by the Borrower on or before the fourteenth (14th) day after the Borrowing Date for such Swing Line Loan; provided, that such payment shall not be made by the proceeds of any other Swing Line Loans. In addition, the Swing Line Lender (i) may at any time in its sole discretion with respect to any outstanding Swing Line Loan, or (ii) if not previously repaid by the Borrower, shall on the fourteenth (14th) day after the Borrowing Date of any Swing Line Loan, require each Lender (including the Swing Line Lender) to make a Revolving Loan in the amount of such Lender’s Pro Rata Share of such Swing Line Loan (including, without limitation and to the extent available, any interest accrued and unpaid thereon), for the purpose of repaying such Swing Line Loan. Not later than noon (Charlotte, North Carolina time) on the date of any notice received pursuant to this Section 2.23.4, each Lender shall make available its required Revolving Loan, in funds immediately available in Charlotte, North Carolina to the Agent at its address specified pursuant to Article XIII. Revolving Loans made pursuant to this Section 2.23.4 shall initially be Floating Rate Loans and thereafter may be continued as Floating Rate Loans or converted into Eurodollar Loans in the manner provided in Section 2.9 and subject to the other conditions and limitations set forth

in this Article II. Unless a Lender shall have notified the Swing Line Lender, prior to its making any Swing Line Loan, that any applicable condition precedent set forth in Sections 4.1 or 4.2 had not then been satisfied, such Lender’s obligation to make Revolving Loans pursuant to this Section 2.23.4 to repay Swing Line Loans shall be unconditional, continuing, irrevocable and absolute and shall not be affected by any circumstances, including, without limitation, (a) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against the Agent, the Swing Line Lender or any other Person, (b) the occurrence or continuance of a Default or Unmatured Default, (c) any adverse change in the condition (financial or otherwise) of the Borrower, or (d) any other circumstances, happening or event whatsoever. In the event that any Lender fails to make payment to the Agent of any amount due under this Section 2.23.4, the Agent shall be entitled to receive, retain and apply against such obligation the principal and interest otherwise payable to such Lender hereunder until the Agent receives such payment from such Lender or such obligation is otherwise fully satisfied. In addition to the foregoing, if for any reason any Lender fails to make payment to the Agent of any amount due under this Section 2.23.4, such Lender shall be deemed, at the option of the Agent, to have unconditionally and irrevocably purchased from the Swing Line Lender, without recourse or warranty, an undivided interest and participation in the applicable Swing Line Loan in the amount of such Revolving Loan, and such interest and participation may be recovered from such Lender together with interest thereon at the Federal Funds Effective Rate for each day during the period commencing on the date of demand and ending on the date such amount is received. On the Revolving Credit Termination Date, the Borrower shall repay in full the outstanding principal balance of the Swing Line Loans.

ARTICLE III

YIELD PROTECTION; TAXES

3.1 Yield Protection. If, on or after the date of this Agreement, the adoption of any law, rule or regulation or any change in any such law, rule or regulation or in the interpretation or administration thereof by any governmental, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender or applicable Lending Installation with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency:

3.1.1 subjects any Lender or any applicable Lending Installation to any Taxes, or changes the basis of taxation of payments (other than with respect to Excluded Taxes) to any Lender in respect of its Eurodollar Loans, Facility LCs or participations therein, or

3.1.2 imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or any applicable Lending Installation (other than reserves and assessments taken into account in determining the interest rate applicable to Eurodollar Advances), or

3.1.3 imposes any other condition the result of which is to increase the cost to any Lender or any applicable Lending Installation of making, funding or maintaining its Commitment or Eurodollar Loans or Swing Line Loans or of issuing or participating in Facility LCs or Swing Line Loans, or reduces any amount receivable by any Lender or any applicable Lending Installation in connection with its Commitment or Eurodollar Loans or Swing Line Loans or Facility LCs (including participations therein), or requires any Lender or any applicable Lending Installation to make any payment calculated by reference to the amount of Commitment or

Eurodollar Loans or Swing Line Loans or Facility LCs (including participations therein) held or interest or LC Fees received by it, by an amount deemed material by such Lender,

and the result of any of the foregoing is to increase the cost to such Lender or applicable Lending Installation of making or maintaining its Eurodollar Loans, Swing Line Loans or Commitment or of issuing or participating in Facility LCs or Swing Line Loans, as applicable, or to reduce the return received by such Lender or applicable Lending Installation in connection with such Eurodollar Loans, Swing Line Loans, Commitment or issuing or participating in Facility LCs or Swing Line Loans, then, within fifteen (15) days of demand, accompanied by the written statement required by Section 3.6, by such Lender, the Borrower shall pay such Lender such additional amount or amounts as will compensate such Lender for such increased cost or reduction in amount received; provided that no such amount shall be payable with respect to any period commencing more than ninety (90) days prior to the date such Lender first notifies the Borrower of its intention to demand compensation therefor under this Section 3.1.

3.2 Changes in Capital Adequacy Regulations. If a Lender determines the amount of capital required or expected to be maintained by such Lender, any Lending Installation of such Lender or any corporation controlling such Lender is increased as a result of a “Change” (as defined below), then, within fifteen (15) days of demand, accompanied by the written statement required by Section 3.6, by such Lender, the Borrower shall pay such Lender the amount necessary to compensate for any shortfall in the rate of return on the portion of such increased capital which such Lender determines is attributable to this Agreement, its Loans or its Commitment to make Loans and issue or participate in Facility LCs or Swing Line Loans, as applicable, hereunder (after taking into account such Lender’s policies as to capital adequacy); provided that no such amount shall be payable with respect to any period commencing more than thirty (30) days before the date such Lender first notifies the Borrower of its intention to demand compensation under this Section 3.2. “Change” means (i) any change after the date of this Agreement in the Risk-Based Capital Guidelines or (ii) after the date of this Agreement, the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change in any such law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency given or made after the date of this Agreement. “Risk-Based Capital Guidelines” means (i) the risk-based capital guidelines in effect in the United States on the date of this Agreement, including transition rules, and (ii) the corresponding capital regulations promulgated by regulatory authorities outside the United States implementing the July 1988 report of the Basle Committee on Banking Regulation and Supervisory Practices Entitled “International Convergence of Capital Measurements and Capital Standards,” including transition rules, and any amendments to such regulations adopted prior to the date of this Agreement.

3.3 Availability of Types of Advances. If any Lender determines that maintenance of its Eurodollar Loans at a suitable Lending Installation would violate any applicable law, rule, regulation, or directive, whether or not having the force of law, or if the Required Lenders determine that (i) deposits of a type and maturity appropriate to match fund Eurodollar Advances are not available or (ii) the interest rate applicable to Eurodollar Advances does not accurately reflect the cost of making or maintaining Eurodollar Advances, then the Agent shall suspend the availability of Eurodollar Advances and require any affected Eurodollar Advances to be repaid or converted to Floating Rate Advances on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by law, subject to the payment of any funding indemnification amounts required by Section 3.4.

3.4 Funding Indemnification. If any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, or a Eurodollar Advance is not made, continued or converted on the date specified by the

Borrower in a Borrowing Notice or a Conversion/Continuation Notice for any reason other than default by the Lenders, or a Eurodollar Advance is not prepaid on the date specified by the Borrower pursuant to Section 2.7 for any reason, or if a Eurodollar Advance is assigned other than on the last day of an Interest Period therefor as a result of a request by the Borrower pursuant to Section 2.19 (other than with respect to the replacement of a Defaulting Lender), the Borrower will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including, without limitation, any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance.

3.5 Taxes. (i) All payments by the Borrower to or for the account of any Lender or the Agent hereunder or under any Note shall be made free and clear of and without deduction for any and all Taxes. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to any Lender or the Agent, (a) 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 3.5) such Lender or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (b) the Borrower shall make such deductions, (c) the Borrower shall pay the full amount deducted to the relevant authority in accordance with applicable law and (d) the Borrower shall furnish to the Agent the original copy of a receipt evidencing payment thereof or, if a receipt cannot be obtained with reasonable efforts, such other evidence of payment as is reasonably acceptable to the Agent, in each case within thirty (30) days after such payment is made.

(ii) In addition, the Borrower shall pay any present or future stamp or documentary taxes and any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under any Note or Facility LC Application or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note or Facility LC Application (“Other Taxes”).

(iii) The Borrower shall indemnify the Agent and each Lender for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed on amounts payable under this Section 3.5) paid by the Agent or such Lender as a result of its Commitment, any Loans made by it hereunder, any Facility LC issued or participated in by it hereunder, or otherwise in connection with its participation in this Agreement and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. Payments due under this indemnification shall be made within thirty (30) days of the date the Agent or such Lender makes demand therefor pursuant to Section 3.6.

(iv) Each Lender that is not incorporated under the laws of the United States of America or a state thereof (each a “Non-U.S. Lender”) agrees that it will, not more than ten (10) Business Days after the date on which it becomes a party to this Agreement (but in any event before a payment is due to it hereunder), (i) deliver to each of the Borrower and the Agent two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI, certifying in either case that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, or (ii) in the case of a Non-U.S. Lender that is fiscally transparent, deliver to the Agent a United States Internal Revenue Form W-8IMY together with the applicable accompanying forms, W-8 or W-9, as the case may be, and certify that it is entitled to an exemption from United States withholding tax. Each Non-U.S. Lender further undertakes to deliver to each of the Borrower and the Agent (x) renewals or additional copies of such form (or any successor form) on or before the date that such form expires or becomes obsolete, and (y) after the occurrence of any event requiring a change in the most recent forms so delivered by it, such additional forms or amendments thereto as may be reasonably requested by the Borrower or the Agent. All forms or amendments described in the

preceding sentence shall certify that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form or amendment with respect to it and such Lender advises the Borrower and the Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax.

(v) For any period during which a Non-U.S. Lender has failed to provide the Borrower with an appropriate form pursuant to clause (iv) above (unless such failure is due to a change in treaty, law or regulation, or any change in the interpretation or administration thereof by any governmental authority, occurring subsequent to the date on which a form originally was required to be provided), such Non-U.S. Lender shall not be entitled to gross up or indemnification under this Section 3.5 with respect to Taxes imposed by the United States; provided that, should a Non-U.S. Lender which is otherwise exempt from withholding tax become subject to Taxes because of its failure to deliver a form required under clause (iv) above, the Borrower shall take such steps as such Non-U.S. Lender shall reasonably request to assist such Non-U.S. Lender to recover such Taxes.

(vi) Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments under this Agreement or any Note pursuant to the law of any relevant jurisdiction or any treaty shall deliver to the Borrower (with a copy to the Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate.

(vii) If the U.S. Internal Revenue Service or any other governmental authority of the United States or any other country or any political subdivision thereof asserts a claim that the Agent or the Borrower did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered or properly completed, because such Lender failed to notify the Agent of a change in circumstances which rendered its exemption from withholding ineffective, or for any other reason), such Lender shall indemnify the Agent and the Borrower fully for all amounts paid, directly or indirectly, by the Agent or the Borrower, as the case may be, as tax, withholding therefor, or otherwise, including penalties and interest, and including taxes imposed by any jurisdiction on amounts payable to the Agent or the Borrower, as the case may be, under this subsection, together with all costs and expenses related thereto (including attorneys fees and time charges of attorneys for the Agent or the Borrower, as the case may be, which attorneys may be employees of the Agent or the Borrower, as the case may be). The obligations of the Lenders under this Section 3.5(vii) shall survive the payment of the Obligations and termination of this Agreement.

(viii) In the event that the Borrower makes a payment for the account of any Lender and such Lender, in its reasonable judgment, determines that it has finally and irrevocably received or been granted a credit against or release or remission for, or repayment of, any tax paid or payable by it in respect of or calculated with reference to the deduction or withholding giving rise to such payment, such Lender shall, to the extent that it determines that it can do so without prejudice to the retention of the amount of such credit, relief, remission or repayment, pay to the Borrower such amount as such Lender shall, in its reasonable judgment, have determined to be attributable to such deduction or withholding and which will leave such Lender (after such payment) in no worse position than it would have been in if the Borrower had not been required

to make such deduction or withholding. Nothing herein contained shall interfere with the right of a Lender to arrange its tax affairs in whatever manner it thinks fit or oblige any Lender to claim any tax credit or to disclose any information in relation to its tax affairs or any computations in respect thereof or require any Lender to do anything that would prejudice its ability to benefit from any other credits, relief, remissions or repayments to which it may be entitled.

3.6 Lender Statements; Survival of Indemnity. Each Lender shall deliver a written statement of such Lender to the Borrower (with a copy to the Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth in reasonable detail the calculations upon which such Lender determined such amount and shall be final, conclusive and binding on the Borrower in the absence of manifest error. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the Eurodollar Rate applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement of any Lender shall be payable within fifteen (15) days after demand and receipt by the Borrower of such written statement. The obligations of the Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive payment of the Obligations and termination of this Agreement.

3.7 Alternative Lending Installation. To the extent reasonably possible, each Lender shall designate an alternate Lending Installation with respect to its Eurodollar Loans to reduce any liability of the Borrower to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of Eurodollar Advances under Section 3.3, so long as such designation is not, in the reasonable judgment of such Lender, disadvantageous to such Lender. A Lender’s designation of an alternative Lending Installation shall not affect the Borrower’s rights under Section 2.19 to replace a Lender.

The execution and delivery by the Borrower of the Loan Documents (as in effect on the date that this representation is made or deemed made) and the performance of its obligations thereunder have been duly authorized by proper corporate or other applicable proceedings, and the Loan Documents to which the Borrower is a party constitute legal, valid and binding obligations of the Borrower enforceable against the Borrower in accordance with their terms, except as enforceability may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally.

5.3 No Conflict; Government Consent. Neither the execution and delivery by the Borrower of the Loan Documents, nor the consummation of the transactions therein contemplated, nor compliance with the provisions thereof will (i) violate or conflict with the Borrower’s or any Material Subsidiary’s articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, by-laws, or operating or other management agreement, as the case may be, or (ii) violate (a) any law, rule, regulation, order, writ, judgment, injunction, decree or award binding on the Borrower or any of its Subsidiaries or (b) contravene or conflict with the provisions of any indenture, instrument or agreement to which the Borrower or any of its Subsidiaries is a party or is subject, or by which it, or its Property, is bound, or conflict with or constitute a default thereunder, or result in, or require, the creation or imposition of any Lien in, of or on the Property of the Borrower or a Subsidiary pursuant to the terms of any such indenture, instrument or agreement, unless such violation with respect to this clause (ii) would not have or could not reasonably be expected to have a Material Adverse Effect. No order, consent, adjudication, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by the Borrower or any of its Subsidiaries, is required to be obtained by the Borrower or any of its Subsidiaries in connection with the execution and delivery of the Loan Documents, the borrowings under this Agreement, the payment and performance by the Borrower of the Obligations thereunder or the legality, validity, binding effect or enforceability of any of the Loan Documents.

ARTICLE VIII

ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

8.1

Acceleration/Remedies .

8.1.1 (i) If any Default described in Section 7.6 or 7.7 occurs with respect to the Borrower, the obligations of the Lenders, including the Swingline Lender, to make Loans hereunder and the obligation and power of the LC Issuer to issue Facility LCs shall automatically terminate and the Obligations shall immediately become due and payable without any election or action on the part of the Agent, the LC Issuer or any Lender, and the Borrower will be and become thereby unconditionally obligated, without any protest, notice, act or demand (all of which are expressly waived by the Borrower), to pay to the Agent for the account of the Lenders an amount in immediately available funds, which funds shall be held in the Facility LC Collateral Account, equal to the difference of (x) 100% of the amount of LC Obligations at such time less (y) the amount on deposit in the Facility LC Collateral Account at such time which is free and clear of all rights and claims of third parties (other than the Agent and the Lenders) and has not been applied against the Obligations (the “Collateral Shortfall Amount”). If any other Default occurs, the Agent may with the consent of the Required Lenders (a) terminate or suspend the obligations of the Lenders to make Loans hereunder and the obligation and power of the LC Issuer to issue Facility LCs, or declare the Obligations to be due and payable, or both, whereupon the Obligations shall become immediately due and payable, without presentment, demand, protest or notice of any kind, all of which the Borrower hereby expressly waives and (b) upon notice to the Borrower and in addition to the continuing right to demand payment of all amounts payable under this Agreement, make demand on the Borrower to pay (a “Funding Demand”), and the Borrower will forthwith upon such demand and without any further notice or act pay to the Agent the Collateral Shortfall Amount which funds shall be deposited in the Facility LC Collateral Account.

(ii) If at any time while any Default is continuing with respect to which the Agent has made a Funding Demand, the Agent determines that the Collateral Shortfall Amount at such time is greater than zero, the Agent may make demand on the Borrower to pay, and the Borrower will, forthwith upon such demand and without any further notice or act, pay to the Agent the Collateral Shortfall Amount, which funds shall be deposited in the Facility LC Collateral Account.

(iii) The Agent may at any time or from time to time after funds are deposited in the Facility LC Collateral Account, apply such funds to the payment of the Obligations.

(iv) Except as expressly provided below, at any time while any Default is continuing, neither the Borrower nor any Person claiming on behalf of or through the Borrower shall, unless the Required Lenders shall otherwise consent, have any right to withdraw any of the funds held in the Facility LC Collateral Account. Upon request of the Borrower, the Agent shall permit the Borrower to withdraw from the Facility LC Collateral Account, so long as no Default then exists, the balance of the Facility LC Collateral Account. If a Default then exists, the Agent shall, upon the request of the Borrower apply the Excess Balance (as defined below) to the payment of the Obligations; provided further that if there are no Obligations (other than LC Obligations) due and payable, the Agent shall, upon request of the Borrower, release to the Borrower the Excess Balance. As used herein, “Excess Balance” means the amount by which the balance of the Facility LC Collateral Account exceeds the amount of L/C Obligations. In addition, after all of the Obligations have been paid in full and the Aggregate Commitment has been terminated, any

funds remaining in the Facility LC Collateral Account shall be returned by the Agent to the Borrower or paid to whomever may be legally entitled thereto at such time. Notwithstanding anything in this Agreement to the contrary, to the extent the Borrower has deposited cash in the Facility LC Collateral Account in accordance with the requirements of 2.20.1, the Borrower shall not be permitted to withdraw such amounts from the Facility LC Collateral Account until the Facility LC’s secured thereby have been cancelled and returned to the applicable LC Issuer on terms and conditions satisfactory to such LC Issuer.

(v) If, after acceleration of the maturity of the Obligations or termination of the obligations of the Lenders to make Loans and the obligation and power of the LC Issuer to issue Facility LCs hereunder as a result of any Default (other than any Default as described in Section 7.2(a), 7.2(b), 7.6 or 7.7 with respect to the Borrower) and before any judgment or decree for the payment of the Obligations due shall have been obtained or entered, the Required Lenders (in their sole discretion) shall so direct, the Agent shall, by notice to the Borrower, rescind and annul such acceleration and/or termination.

(vi) Each Lender has, to the extent permitted by law, a separate right of payment and shall be considered a separate “creditor” holding a separate “claim” within the meaning of Section 101(5) of the Bankruptcy Code or any other insolvency statute.

8.1.2 Notwithstanding any other provision of this Agreement, after the occurrence and during the continuance of a Default, all amounts collected or received by the Agent or any Lender on account of amounts outstanding under any of the Loan Documents shall be paid over or delivered as follows:

FIRST, to the payment of all reasonable out-of-pocket costs and expenses (including without limitation reasonable attorneys’ fees) of the Agent and the Lenders in connection with enforcing the rights of the Lenders under the Loan Documents, pro rata as set forth below;

SECOND, to payment of any fees owed to the Agent, or any Lender, pro rata as set forth below;

THIRD, to the payment of all accrued interest payable to the Lenders hereunder, pro rata as set forth below;

FOURTH, to the payment of the outstanding principal amount of the Loans and to the payment or cash collateralization of the outstanding LC Obligations, pro rata, as set forth below;

FIFTH, to all other obligations which shall have become due and payable under the Loan Documents and not repaid pursuant to clauses “FIRST” through “FOURTH” above; and

SIXTH, to the payment of the surplus, if any, to whomever may be lawfully entitled to receive such surplus.

In carrying out the foregoing, (a) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category; (b) each of the Lenders shall receive an amount equal to its Pro Rata Share of amounts available to be applied; and (c) to the extent that any amounts available for distribution pursuant to clause “FOURTH” above are attributable to the issued but undrawn amount of outstanding Facility LC’s, such amounts shall be held by the Agent in the Facility LC Collateral Account and applied (i) first, to reimburse the LC Issuer from time to time for any drawings under such Facility LC’s and

(ii) then, following the expiration of all Facility LC’s, to all other obligations of the types described in clauses “FOURTH”, “FIFTH” and “SIXTH” above in the manner provided in this Section 8.1.2.

8.2 Amendments. Subject to the provisions of this Section 8.2, the Required Lenders (or the Agent with the consent in writing of the Required Lenders) and the Borrower may enter into agreements supplemental hereto for the purpose of adding or modifying any provisions to the Loan Documents or changing in any manner the rights of the Lenders or the Borrower hereunder or waiving any Default hereunder; provided, however, that no such supplemental agreement shall, without the consent of all of the Lenders affected thereby:

8.2.1 Except as specifically provided in this Agreement, extend the final maturity of any Loan, extend the expiry date of any Facility LC to a date after the date that is one year after the Revolving Credit Termination Date, or postpone any regularly scheduled payment of principal of any Loan or forgive or reduce all or any portion of the principal amount thereof, or any Reimbursement Obligations related thereto, or reduce the rate or extend the time of payment of interest or fees thereon or Reimbursement Obligations related thereto (other than a waiver of the application of the default rate of interest pursuant to Section 2.11 hereof).

8.2.2 Reduce the percentage specified in the definition of Required Lenders or any other percentage of Lenders specified to be the applicable percentage in this Agreement to act on specified matters or amend the definition of “Pro Rata Share”.

8.2.3 Except as specifically provided in this Agreement, (i) extend the Revolving Credit Termination Date, or (ii) reduce the amount or extend the payment date for, the mandatory payments required under Section 2.2, or (iii) increase the amount of the Commitment of any Lender hereunder or the commitment to issue Facility LCs, or (iv) permit the Borrower to assign its rights or obligations under this Agreement.

8.2.4

Amend this Section 8.2 or Sections 7.2 or 9.6 or amend Article XI.

8.2.5 Alter the manner in which payments or prepayments of principal, interest or other amounts hereunder shall be applied as among the Lenders or Types of Loans.

No amendment of any provision of this Agreement relating to the Agent shall be effective without the written consent of the Agent, no amendment of any provision of this Agreement relating to the Swing Line Lender or any Swing Line Loans shall be effective without the written consent of the Swing Line Lender and no amendment of any provision relating to the LC Issuer shall be effective without the written consent of the LC Issuer. The Agent may waive payment of the fee required under Section 12.3.3 without obtaining the consent of any other party to this Agreement.

8.3 Preservation of Rights. No delay or omission of the Lenders or the Agent to exercise any right under the Loan Documents shall impair such right or be construed to be a waiver of any Default or an acquiescence therein, and the making of a Credit Extension notwithstanding the existence of a Default or the inability of the Borrower to satisfy the conditions precedent to such Credit Extension shall not constitute any waiver or acquiescence. Any single or partial exercise of any such right shall not preclude other or further exercise thereof or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Loan Documents whatsoever shall be valid unless in writing signed by the Lenders required pursuant to Section 8.2, and then only to the extent in such writing specifically set forth. All remedies contained in the Loan Documents or by law afforded

shall be cumulative and all shall be available to the Agent and the Lenders until the Obligations have been paid in full.

9.3 Headings. Section headings in the Loan Documents are for convenience of reference only, and shall not govern the interpretation of any of the provisions of the Loan Documents.

9.4 Entire Agreement. The Loan Documents embody the entire agreement and understanding among the Borrower, the Agent and the Lenders and supersede all prior agreements and understandings among the Borrower, the Agent and the Lenders relating to the subject matter thereof (including any previously executed commitment letters among the parties or, in the case of the Borrower, its predecessors), other than those contained in the Fee Letters described in Section 10.13 which shall survive and remain in full force and effect during the term of this Agreement.

9.5 Several Obligations; Benefits of this Agreement. The respective obligations of the Lenders hereunder are several and not joint and no Lender shall be the partner or agent of any other (except to the extent to which the Agent is authorized to act as such). The failure of any Lender to perform any of its obligations hereunder shall not relieve any other Lender from any of its obligations hereunder. This Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and assigns, provided, however, that the parties hereto expressly agree that each Arranger shall enjoy the benefits of the provisions of Sections 9.6, 9.10 and 10.11 to the extent specifically set forth therein and shall have the right to enforce such provisions on its own behalf and in its own name to the same extent as if it were a party to this Agreement.

9.6 Expenses; Indemnification. (i) The Borrower shall reimburse the Agent and each Arranger for any reasonable costs, internal charges and out-of-pocket expenses (including reasonable attorneys’ and paralegals’ fees and time charges of attorneys for the Agent, which attorneys may be employees of the Agent and expenses of and fees for other advisors and professionals engaged by the Agent or any Arranger) paid or incurred by the Agent or any Arranger in connection with the investigation, preparation, negotiation, documentation, execution, delivery, syndication, distribution (including, without limitation, via the internet), review, amendment, modification and administration of the Loan Documents. The Borrower also agrees to reimburse the Agent, the Syndication Agent, the Co-Documentation Agents, the Arrangers and the Lenders for any reasonable costs, internal charges and out-of-pocket expenses (including reasonable attorneys’ and paralegals’ fees and time charges and expenses of attorneys and paralegals for the Agent, the Syndication Agent, the Co-Documentation Agents, the Arrangers and the Lenders, which attorneys and paralegals may be employees of the Agent, the Syndication Agent, the Co-Documentation Agents, the Arrangers or the Lenders) paid or incurred by the Agent, the Syndication Agent, the Co-Documentation Agents, the Arrangers or any Lender in connection with the collection and enforcement of the Loan Documents.

For the avoidance of doubt, the provisions of this clause (ii) shall not operate to expand the obligations of the Borrower under Section 9.6(i) with respect to the reimbursement of costs and expenses incurred by the Lenders in connection with the investigation, preparation, negotiation, documentation, execution, delivery, syndication, distribution (including, without limitation, via the internet), review, amendment, modification and administration (as distinguished from the enforcement) of the Loan Documents.

The obligations of the Borrower under this Section 9.6 shall survive the termination of this Agreement.

9.8 Accounting. Except as provided to the contrary herein, all accounting terms used in the calculation of any financial covenant or test shall be interpreted and all accounting determinations hereunder in the calculation of any financial covenant or test shall be made in accordance with Agreement Accounting Principles. If any changes in GAAP are hereafter required or permitted and are adopted by the Borrower or any of its Subsidiaries with the agreement of its independent certified public accountants and such changes result in a change in the method of calculation of any of the financial covenants, tests, restrictions or standards herein or in the related definitions or terms used therein (“Accounting Changes”), the parties hereto agree, at the Borrower’s request, to enter into negotiations, in good faith, in order to amend such provisions in a credit neutral manner so as to reflect equitably such changes with the desired result that the criteria for evaluating the Borrower’s and its Subsidiaries’ financial condition shall be the same after such changes as if such changes had not been made; provided, however, until such provisions are amended in a manner reasonably satisfactory to the Agent and the Required Lenders, no Accounting Change shall be given effect in such calculations. In the event such amendment is entered into, all references in this Agreement to Agreement Accounting Principles shall mean GAAP as of the date of such amendment. Notwithstanding the foregoing, all financial statements (other than pro forma financial statements or projections) to be delivered by the Borrower pursuant to Section 6.1 shall be prepared in accordance with GAAP in effect at such time (other than in the case of interim financial statements, with respect to the absence of footnotes and year end adjustments).

9.9 Severability of Provisions. Any provision in any Loan Document that is held to be inoperative, unenforceable, or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining provisions in that jurisdiction or the operation, enforceability, or validity of that provision in any other jurisdiction, and to this end the provisions of all Loan Documents are declared to be severable.

9.10 Nonliability of Lenders. The relationship between the Borrower on the one hand and the Lenders and the Agent on the other hand shall be solely that of borrower and lender.

Neither the Agent nor any Arranger or Lender shall have any liability with respect to, and the Borrower hereby waives, releases and agrees not to xxx for, any special, indirect, consequential or punitive damages suffered by the Borrower in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby.

9.12 Lenders Not Utilizing Plan Assets. Each Lender represents and warrants that none of the consideration used by such Lender to make its Loans constitutes for any purpose of ERISA or Section 4975 of the Code assets of any “plan” as defined in Section 3(3) of ERISA or Section 4975 of the Code and the rights and interests of such Lender in and under the Loan Documents shall not constitute such “plan assets” under ERISA.

9.13 Nonreliance. Each Lender hereby represents that it is not relying on or looking to any margin stock (as defined in Regulation U of the Board of Governors of the Federal Reserve System) for the repayment of the Credit Extensions provided for herein.

9.15 USA Patriot Act Notification. The following notification is provided to the Borrower pursuant to the Patriot Act:

IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government of the United States of America fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each Person that opens an account, including any deposit account, treasury management account, loan, other extension of credit, or other financial services product. Accordingly, when the Borrower opens an account, the Agent and the Lenders will ask for the Borrower’s name, tax identification number, business address, and other information that will allow the Agent and the Lenders to identify the Borrower. The Agent and the Lenders may also ask to see the Borrower’s legal organizational documents or other identifying documents.

9.16 Defaulting Lender. Each Lender understands and agrees that if such Lender is a Defaulting Lender then it shall not be entitled to vote on any matter requiring the consent of the Required Lenders or to object to any matter requiring the consent of all the Lenders; provided, however, that (a) a Lender’s Commitment may not be increased without its consent whether or not it is a Defaulting Lender and (b) all other benefits and obligations under the Loan Documents shall apply to such Defaulting Lender.

9.17 Excluded Subsidiaries. The Borrower shall have the right, at any time with prior written notice to the Agent, to (i) designate any Subsidiary as an Excluded Subsidiary in accordance with the requirements of such definition or (ii) remove any Subsidiary from being an Excluded Subsidiary; provided that the Borrower shall only have the right to make any such designation one time with respect to each Subsidiary and once a Subsidiary is removed by the Borrower from being an Excluded Subsidiary it may not be re-designated one at a later date.

Each of the Lenders hereby agrees to assert no claim against the Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Lender hereby waives.

10.2 Powers. The Agent shall have and may exercise such powers under the Loan Documents as are specifically delegated to the Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto. The Agent shall have no implied duties to the Lenders, or any obligation to the Lenders to take any action thereunder except any action specifically provided by the Loan Documents to be taken by the Agent.

10.3 General Immunity. Neither the Agent nor any of its directors, officers, agents or employees shall be liable to the Borrower, the Lenders or any Lender for any action taken or omitted to be taken by it or them hereunder or under any other Loan Document or in connection herewith or therewith except to the extent such action or inaction is determined in a final non-appealable judgment by a court of competent jurisdiction to have arisen from the gross negligence or willful misconduct of such Person.

10.4 No Responsibility for Loans, Recitals, etc. Neither the Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify (a) any statement, warranty or representation made in connection with any Loan Document or any borrowing hereunder; (b) the performance or observance of any of the covenants or agreements of any obligor under any Loan Document, including, without limitation, any agreement by an obligor to furnish information directly to each Lender; (c) the satisfaction of any condition specified in Article IV, except receipt of items required to be delivered solely to the Agent; (d) the existence or possible existence of any Default or Unmatured Default; (e) the validity, enforceability, effectiveness, sufficiency or genuineness of any Loan Document or any other instrument or writing furnished in connection therewith; (f) the value, sufficiency, creation, perfection or priority of any Lien in any collateral security; or (g) the financial condition of the Borrower or any guarantor of any of the Obligations or of any of the Borrower’s or any such guarantor’s respective Subsidiaries. The Agent shall have no duty to disclose to the Lenders information that is not required to be furnished by the Borrower to the Agent at such time, but is voluntarily furnished by the Borrower to the Agent (either in its capacity as Agent or in its individual capacity).

10.5 Action on Instructions of Lenders. The Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any other Loan Document in accordance with written instructions signed by the Required Lenders, and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders. The Lenders hereby acknowledge that the Agent shall be under no duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or any other Loan Document unless it shall be requested in writing to do so by the Required Lenders. The Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Loan Document unless it shall first be indemnified to its satisfaction by the Lenders pro rata against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action.

10.6 Employment of Agents and Counsel. The Agent may execute any of its duties as Agent hereunder and under any other Loan Document by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Lenders, except as to money or securities received by it or its authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. The Agent shall be entitled to advice of counsel concerning the contractual arrangement between the Agent and the Lenders and all matters pertaining to the Agent’s duties hereunder and under any other Loan Document.

10.7 Reliance on Documents; Counsel. The Agent shall be entitled to rely upon any Note, notice, consent, certificate, affidavit, letter, telegram, statement, paper or document reasonably believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and, in

respect to legal matters, upon the opinion of counsel selected by the Agent, which counsel may be employees of the Agent.

10.8 Agent’s Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Agent, the Syndication Agent and the Co-Documentation Agents ratably in proportion to the Lenders’ Pro Rata Shares (determined at the time such reimbursement or indemnity is sought) of the Aggregate Commitment (or, if the Aggregate Commitment has been terminated, of the Outstanding Credit Exposure) (i) for any amounts not reimbursed by the Borrower for which the Agent, the Syndication Agent or any Co-Documentation Agent is entitled to reimbursement by the Borrower under the Loan Documents, (ii) for any other expenses incurred by the Agent, the Syndication Agent, or any Co-Documentation Agent on behalf of the Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents (including, without limitation, for any expenses incurred by the Agent or the Syndication Agent in connection with any dispute between the Agent or the Syndication Agent and any Lender or between two or more of the Lenders) and (iii) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Agent, the Syndication Agent, or any Co-Documentation Agent in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including, without limitation, for any such amounts incurred by or asserted against the Agent, the Syndication Agent, or any Co-Documentation Agent in connection with any dispute between the Agent, the Syndication Agent, the Co-Documentation Agents and any Lender or between two or more of the Lenders), or the enforcement of any of the terms of the Loan Documents or of any such other documents; provided that (i) no Lender shall be liable for any of the foregoing to the extent any of the foregoing is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the party seeking indemnification and (ii) any indemnification required pursuant to Section 3.5(vii) shall, notwithstanding the provisions of this Section 10.8, be paid by the relevant Lender in accordance with the provisions thereof. The obligations of the Lenders under this Section 10.8 shall survive payment of the Obligations and termination of this Agreement.

10.9 Notice of Default. The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Unmatured Default hereunder unless the Agent has received written notice from a Lender or the Borrower referring to this Agreement describing such Default or Unmatured Default and stating that such notice is a “notice of default”. In the event that the Agent receives such a notice, the Agent shall give prompt notice thereof to the Lenders.

10.10 Rights as a Lender. In the event the Agent is a Lender, the Agent shall have the same rights and powers hereunder and under any other Loan Document with respect to its Commitment and its Loans as any Lender and may exercise the same as though it were not the Agent, and the term “Lender” or “Lenders” shall, at any time when the Agent is a Lender, unless the context otherwise indicates, include the Agent in its individual capacity. The Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other transaction, in addition to those contemplated by this Agreement or any other Loan Document, with the Borrower or any of its Subsidiaries in which the Borrower or such Subsidiary is not restricted hereby from engaging with any other Person. The Agent, in its individual capacity, is not obligated to remain a Lender.

10.11 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent, any Arranger or any other Lender and based on the financial statements prepared by the Borrower and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon the Agent, any Arranger or any other Lender and based on such documents and information as it shall deem appropriate at the

time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents.

10.12 Successor Agent. The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower, such resignation to be effective upon the appointment of a successor Agent or, if no successor Agent has been appointed, forty-five (45) days after the retiring Agent gives notice of its intention to resign. The Agent may be removed at any time with or without cause by written notice received by the Agent from the Required Lenders, such removal to be effective on the date specified by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint, on behalf of the Borrower and the Lenders, an existing Lender to be the successor Agent (which successor Agent shall, unless a Default is then continuing, be approved by the Borrower, such approval not to be unreasonably withheld or delayed). If no successor Agent shall have been so appointed by the Required Lenders within thirty (30) days after the resigning Agent’s giving notice of its intention to resign, then the resigning Agent may appoint, on behalf of the Borrower and the Lenders, an existing Lender to be the successor Agent (which successor Agent shall, unless a Default is then continuing, be approved by the Borrower, such approval not to be unreasonably withheld or delayed). Notwithstanding the previous sentence, the Agent may at any time without the consent of the Borrower or any Lender, appoint any of its Affiliates which is a commercial bank as a successor Agent hereunder. If the Agent has resigned or been removed and no successor Agent has been appointed, the Lenders may perform all the duties of the Agent hereunder and the Borrower shall make all payments in respect of the Obligations to the applicable Lender and for all other purposes shall deal directly with the Lenders. No successor Agent shall be deemed to be appointed hereunder until such successor Agent has accepted the appointment. Any such successor Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning or removed Agent. Upon the effectiveness of the resignation or removal of the Agent, the resigning or removed Agent shall be discharged from its duties and obligations hereunder and under the Loan Documents. After the effectiveness of the resignation or removal of an Agent, the provisions of this Article X shall continue in effect for the benefit of such Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Agent hereunder and under the other Loan Documents. In the event that there is a successor to the Agent by merger, or the Agent assigns its duties and obligations to an Affiliate pursuant to this Section 10.12, then the term “Prime Rate” as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent.

10.13 Agent and Arrangers’ Fees. The Borrower agrees to pay to the Agent and each Arranger, for their respective accounts, the fees agreed to by Enogex, Inc, for and on behalf of the Borrower, the Agent and such Arranger pursuant to those certain letter agreements dated December 14, 2007 (the “Fee Letters”), or as otherwise agreed from time to time.

10.14 Delegation to Affiliates. The Borrower and the Lenders agree that the Agent may delegate any of its duties under this Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate’s directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other protective provisions to which the Agent is entitled under Articles IX and X.

10.15 Syndication Agent and Co-Documentation Agents. None of the Syndication Agent and the Co-Documentation Agents shall have any rights, obligations, liabilities, responsibilities or duties under this Agreement other than those applicable to all Lenders. Without limiting the foregoing, none of the Syndication Agent and the Co-Documentation Agents shall have or be deemed to have a fiduciary relationship with any Lender. Each Lender hereby makes the same acknowledgements with respect to the

Syndication Agent and the Co-Documentation Agents as it makes with respect to the Agent in Section 10.11.

ARTICLE XI

SETOFF; RATABLE PAYMENTS

11.1 Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if the Borrower becomes insolvent, however evidenced, or any Default occurs and is continuing, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness at any time held or owing by any Lender or any Affiliate of any Lender to or for the credit or account of the Borrower may be offset and applied toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or any part thereof, shall then be due.

11.2 Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Outstanding Credit Exposure (other than (i) payments received pursuant to Section 3.1, 3.2, 3.4 or 3.5, (ii) payments in accordance with Section 2.21 to any Lender which has not extended its Commitment pursuant to such Section and (iii) payments to which the LC Issuer or the Swing Line Lender is entitled under Section 2.20.6 or Section 2.23.4, as applicable) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a portion of the Aggregate Outstanding Credit Exposure held by the other Lenders so that after such purchase each Lender will hold its Pro Rata Share of the Aggregate Outstanding Credit Exposure. If any Lender, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their respective Pro Rata Shares of the Aggregate Outstanding Credit Exposure. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

ARTICLE XII

BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

12.1 Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Borrower, the Agent and the Lenders and their respective successors and assigns permitted hereby, except that (i) the Borrower shall not have the right to assign its rights or obligations under the Loan Documents without the prior written consent of each Lender, (ii) any assignment by any Lender must be made in compliance with Section 12.3, and (iii) any transfer by participation must be made in compliance with Section 12.2. Any attempted assignment or transfer by any party not made in compliance with this Section 12.1 shall be null and void, unless such attempted assignment or transfer is treated as a participation in accordance with Section 12.3.3. The parties to this Agreement acknowledge that clause (ii) of this Section 12.1 relates only to absolute assignments and this Section 12.1 does not prohibit assignments creating security interests, including, without limitation, any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank; provided,however , that no such pledge or assignment creating a security interest shall release the transferor Lender from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 12.3. The Agent may treat each Lender which made any Credit Extension or which holds any Note as the owner thereof for all purposes hereof unless and

until such Lender complies with Section 12.3; provided,however , that the Agent may in its discretion (but shall not be required to) follow instructions from the Lender which made any Credit Extension or which holds any Note to direct payments relating to such Credit Extension or Note to another Person. Any assignee of the rights to any Credit Extension or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Lender, who at the time of making such request or giving such authority or consent is the owner of the rights to any Credit Extension (whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any subsequent holder or assignee of the rights to such Credit Extension.

12.2

Participations.

12.2.1 Permitted Participants; Effect. Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time sell to one or more banks or other entities (“Participants”) participating interests in any Outstanding Credit Exposure of such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender under the Loan Documents. In the event of any such sale by a Lender of participating interests to a Participant, such Lender’s obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the owner of its Outstanding Credit Exposure and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents, all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interests, and the Borrower and the Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under the Loan Documents. Notwithstanding the foregoing, unless a Default has occurred and is continuing, the Lenders may not sell participations in respect of their Loans or Commitments to any competitor of the Borrower or any of its Subsidiaries or any other company engaged in the business of selling or distributing energy products.

12.2.2 Voting Rights. Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver with respect to any Credit Extension or Commitment in which such Participant has an interest which would require consent of all of the Lenders pursuant to the terms of Section 8.2.

12.2.3 Benefit of Certain Provisions. The Borrower agrees that each Participant shall be deemed to have the right of setoff provided in Section 11.1 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents; provided that each Lender shall retain the right of setoff provided in Section 11.1 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 11.1, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 11.2 as if each Participant were a Lender. The Borrower further agrees that each Participant shall be entitled to the benefits of Sections 3.1, 3.2, 3.4 and 3.5 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.3; provided that (i) a Participant shall not be entitled to receive any greater payment under Section 3.1, 3.2, 3.4 or 3.5 than the Lender who sold the participating interest to such Participant would have received had it retained such interest for its own account, unless the sale of such interest to such Participant is made with the prior written consent of the Borrower, and (ii) any Participant not incorporated under the laws of the United States of America or any State thereof agrees to comply with the provisions of Section 3.5 to the same extent as if it were a Lender.

12.3

Assignments.

12.3.1 Permitted Assignments. Any Lender may at any time assign to one or more banks or other entities (“Purchasers”) all or any part of its rights and obligations under the Loan Documents. Such assignment shall be substantially in the form of Exhibit C or in such other form as may be agreed to by the parties thereto. Each such assignment with respect to a Purchaser which is not a Lender or an Affiliate of a Lender or an Approved Fund shall either be in an amount equal to the entire applicable Commitment and Outstanding Credit Exposure of the assigning Lender or (unless each of the Borrower and the Agent otherwise consents) be in an aggregate amount not less than $5,000,000. The amount of the assignment shall be based on the Commitment or Outstanding Credit Exposure (if the Commitment has been terminated) subject to the assignment, determined as of the date of such assignment or as of the “Trade Date,” if the “Trade Date” is specified in the assignment. Notwithstanding the foregoing, unless a Default has occurred and is continuing, the Lenders may not make assignments in respect of their Loans or Commitments to any competitor of the Borrower or any other company engaged in the business of selling or distributing energy products.

12.3.2 Consents. The consent of the Agent and the Borrower shall be required prior to an assignment becoming effective; provided that (i) the consent of the Borrower shall not be required if a Default has occurred and is continuing and (ii) no consent shall be required from the Borrower or the Administrative Agent for assignments to a Lender or an Affiliate of a Lender; provided that no Fund shall be a Lender unless it is an Approved Fund. Any consent required under this Section 12.3.2 shall not be unreasonably withheld or delayed; it being acknowledged and agreed however that such consents may be withheld (and it shall not be deemed unreasonable to withhold such consent) if such proposed assignee has not complied with the requirements Section 3.5(iv) or the assignment to such proposed assignee would subject the Borrower to costs, indemnities or limitations of the type described in Article III hereof in excess of those applicable to the assigning Lender.

12.3.3 Effect; Effective Date. Upon (i) delivery to the Agent of an assignment, together with any consents required by Section 12.3.2, and (ii) payment by the assigning Lender of a $3,500 fee to the Agent for processing such assignment (unless such fee is waived by the Agent), such assignment shall become effective on the effective date specified in such assignment. The assignment shall contain a representation and warranty by the Purchaser to the effect that none of the funds, money, assets or other consideration used to make the purchase and assumption of the Commitment and Outstanding Credit Exposure under the applicable assignment agreement constitutes “plan assets” as defined under ERISA and that the rights, benefits and interests of the Purchaser in and under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to this Agreement and any other Loan Document executed by or on behalf of the Lenders and shall have all the rights, benefits and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party thereto, and the transferor Lender shall be released with respect to the Commitment and Outstanding Credit Exposure assigned to such Purchaser without any further consent or action by the Borrower, the Lenders or the Agent. In the case of an assignment covering all of the assigning Lender’s rights, benefits and obligations under this Agreement, such Lender shall cease to be a Lender hereunder but shall continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Documents which survive payment of the Obligations and termination of the Loan Documents. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.3 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 Section 12.2. Upon the consummation of any assignment to a Purchaser pursuant to this Section 12.3.3, the transferor Lender, the Agent and the Borrower shall, if the transferor Lender or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so that, upon cancellation and surrender to the Borrower of the Notes (if any) held by the transferor Lender, new Notes

or, as appropriate, replacement Notes are issued to such transferor Lender, if applicable, and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments (or if the Aggregate Commitment has been terminated, their respective Outstanding Credit Exposure), as adjusted pursuant to such assignment.

12.3.4 Register. The Agent, acting solely for this purpose as an agent of the Borrower (and the Borrower hereby designates the Agent to act in such capacity), shall maintain at one of its offices a copy of each Assignment and Assumption Agreement delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

12.4 Dissemination of Information. The Borrower authorizes each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee”) and any prospective Transferee any and all information in such Lender’s possession concerning the creditworthiness of the Borrower and its Subsidiaries; provided that each Transferee and prospective Transferee agrees to be bound by Section 9.11 of this Agreement.

12.5 Tax Certifications. If any interest in any Loan Document is transferred to any Transferee which is not incorporated under the laws of the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 3.5(iv).

ARTICLE XIII

NOTICES

13.1 Notices. Except as otherwise permitted by Section 2.14 with respect to borrowing notices, all notices, requests and other communications to any party hereunder shall be in writing (including electronic transmission, facsimile transmission or similar writing) and shall be given to such party: (x) in the case of the Borrower, the Lenders or the Agent, at its address or facsimile number set forth on the signature pages hereof or, (y) in the case of any party, at such other address or facsimile number as such party may hereafter specify for the purpose by notice to the Agent and the Borrower in accordance with the provisions of this Section 13.1. Each such notice, request or other communication shall be effective (i) if given by facsimile transmission, when transmitted to the facsimile number specified in this Section and confirmation of receipt is received, (ii) if given by mail, three (3) Business Days after such communication is deposited in the mails with first class postage prepaid, addressed as aforesaid, or (iii) if given by any other means, when delivered (or, in the case of electronic transmission, received) at the address specified in this Section; provided that, subject to Section 2.14, notices to the Agent under Article II shall not be effective until received.

13.2 Change of Address. The Borrower, the Agent and any Lender may each change the address for service of notice upon it by a notice in writing to the other parties hereto.

ARTICLE XIV

COUNTERPARTS

This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one agreement, and any of the parties hereto may execute this Agreement by signing any such counterpart. This Agreement shall be effective when it has been executed by the Borrower, the Agent and the Lenders and each party has notified the Agent by facsimile transmission or telephone that it has taken such action. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed original counterpart of this Agreement.

ARTICLE XV

CHOICE OF LAW; CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL

15.2 CONSENT TO JURISDICTION. THE BORROWER, THE AGENT AND EACH LENDER HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF THE SUPREME COURT OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY AND OF THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER, THE AGENT AND EACH LENDER HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE BORROWER IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY THE BORROWER AGAINST THE AGENT OR ANY LENDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN NEW YORK, NEW YORK.

15.3 WAIVER OF JURY TRIAL; CONSEQUENTIAL DAMAGES. THE BORROWER, THE AGENT AND EACH LENDER HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER. The Borrower, the Agent and each Lender hereby agrees not to assert any claim against the other, or any of their respective directors, officers, employees, attorneys or agents, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise relating to any of the transactions contemplated hereby or by the other Loan Documents.
