S&P/▇▇▇▇▇’▇ Ratings for the Facilities	Applicable Commitment Fee Rate		Applicable Margin for Eurodollar Loans		Applicable Margin for Base Rate Loans		Applicable Margin for Eurodollar Loans		Applicable Margin for Base Rate Loans
Category 1 ³ BB+/Ba1	0.25	%	1.25	%	0.25	%	1.50	%	0.50	%

Category 2 ³ BB/Ba2 < BB+/Ba1	0.375	%	1.50	%	0.50	%	1.50	%	0.50	%

For purposes of the foregoing, (i) if either ▇▇▇▇▇’▇ or S&P shall not have in effect a rating for the Facilities (other than by reason of the circumstances referred to in the penultimate sentence of this definition), then such rating agency shall be deemed to have established a rating in Category 3; (ii) if the ratings established or deemed to have been established by ▇▇▇▇▇’▇ and S&P for the Facilities shall fall within different Categories, the Applicable Margin and the Applicable Commitment Fee Rate shall be based on the higher of the two ratings unless one of the two ratings is two or more Categories lower than the other, in which case the Applicable Margin shall be determined by reference to the Category next below that of the higher of the two ratings; and (iii) if the ratings established or deemed to have been established by ▇▇▇▇▇’▇ and S&P for the Facilities shall be changed (other than as a result of a change in the rating system of ▇▇▇▇▇’▇ or S&P), such change shall be effective as of the date on which it is first announced by the applicable rating agency, irrespective of when notice of such change shall have been furnished by the Borrower to the Payment Agent pursuant to Section 6.02(h) or otherwise. Each change in the Applicable Margin or the Applicable Commitment Fee Rate shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such change. If the rating system of ▇▇▇▇▇’▇ or S&P shall change, or if either such rating agency shall cease to be in the business of rating debt obligations of the same type as the Facilities, the Borrower and the Lenders shall negotiate in good faith to amend this definition to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Applicable Margin shall be determined by reference to the rating most recently in effect prior to such change or cessation.

Each Borrowing of, conversion to or continuation of Eurodollar Rate Loans shall be in a principal amount of $10,000,000 or a whole multiple of $1,000,000 in excess thereof. Except as provided in Section 2.03(c), each Borrowing of or conversion to Base Rate Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof. Each Committed Loan Notice (whether telephonic or written) shall specify (i) whether the Borrower is requesting a Revolving Credit Borrowing or Term L/C Facility Borrowing, a conversion of Revolving Credit Loans or Term L/C Facility Loans from one Type to the other, or a continuation of Eurodollar Rate Loans, (ii) the requested date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (iii) the principal amount of Loans to be borrowed, converted or continued, (iv) the Type of Loans to be borrowed or to which existing Loans are to be converted, and (v) if applicable, the duration of the Interest Period with respect thereto. If the Borrower fails to specify a Type of Loan in a Committed Loan Notice or if the Borrower fails to give a timely notice requesting a conversion or continuation, then the applicable Loans shall be made as, or converted to, Base Rate Loans. Any such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with respect to the applicable Eurodollar Rate Loans. If the Borrower requests a Borrowing of, conversion to, or continuation of Eurodollar Rate Loans in any such Committed Loan Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one month.

(b) Following receipt of a Committed Loan Notice, the Payment Agent shall promptly notify each Lender under the applicable Facility of the amount of its Pro Rata Share of the applicable Loans, and if no timely notice of a conversion or continuation is provided by the Borrower, the Payment Agent shall notify each Lender of the details of any automatic conversion to Base Rate Loans described in Section 2.02(a). In the case of a Borrowing, each Lender under the applicable Facility shall make the

amount of its Loan available to the Payment Agent in immediately available funds at the Payment Agent’s Office not later than 1:00 p.m. (eastern time) on the Business Day specified in the applicable Committed Loan Notice. Upon satisfaction of the applicable conditions set forth in Section 4.02 (and, if such Borrowing is the initial Credit Extension, Section 4.01), the Payment Agent shall make all funds so received available to the Borrower in like funds as received by the Payment Agent either by (i) crediting the account of the Borrower on the books of the Person serving as the Payment Agent with the amount of such funds or (ii) wire transfer of such funds, in each case in accordance with instructions provided to (and reasonably acceptable to) the Payment Agent by the Borrower.

(c) Except as otherwise provided herein, a Eurodollar Rate Loan may be continued or converted only on the last day of an Interest Period for such Eurodollar Rate Loan. During the existence of an Event of Default, no Loans may be requested as, converted to or continued as Eurodollar Rate Loans without the consent of the Required Lenders.

(d) The Payment Agent shall promptly notify the Borrower and the Lenders of the interest rate applicable to any Interest Period for Eurodollar Rate Loans upon determination of such interest rate. The determination of the Eurodollar Rate by the Payment Agent shall be conclusive in the absence of manifest error. At any time that Base Rate Loans are outstanding, the Payment Agent shall notify the Borrower and the Lenders of any change in the Payment Agent’s prime rate used in determining the Base Rate promptly following the public announcement of such change.

(e) After giving effect to all Borrowings, all conversions of Loans from one Type to the other, and all continuations of Loans as the same Type, there shall not be more than ten Interest Periods in effect.

(f) The failure of any Lender to make the Loan to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Loan on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Loan to be made by such other Lender on the date of any Borrowing.

2.03. Letters of Credit.

(a) Revolving L/C Sublimit; Term L/C Facility Letters of Credit.

(i) Subject to the terms and conditions set forth herein, (A) the Revolving L/C Issuers agree, in reliance upon the agreements of the other Revolving Credit Lenders set forth in this Section 2.03, (1) from time to time on any Business Day during the period from the Closing Date until the Revolving Letter of Credit Expiration Date, to issue Revolving Letters of Credit for the account of the Borrower (it being understood and agreed that subject to the other terms herein, the Borrower may obtain for its account Revolving Letters of Credit on behalf of the Parent Guarantor or any of its Affiliates), and to amend or renew Revolving Letters of Credit previously issued by it, in accordance with Section 2.03(b), and (2) to honor drafts under the Letters of Credit; and (B) the Revolving Credit Lenders severally agree to participate in Revolving Letters of Credit issued for the account of the Borrower; provided that no Revolving L/C Issuer shall be obligated to make any Revolving L/C Credit Extension with respect to any Revolving Letter of Credit, and no Revolving Credit Lender shall be obligated to participate in any Revolving Letter of Credit if as of the date of such Revolving L/C Credit Extension, (x) the Total Outstandings under the Revolving Credit Facility would exceed the aggregate Revolving Credit Commitments, (y) the sum of the aggregate Outstanding Amount of the Revolving Credit Loans of any Revolving Credit Lender plus such

Lender’s Pro Rata Share of the Outstanding Amount of all Revolving L/C Obligations would exceed such Lender’s Revolving Credit Commitment or (z) the Outstanding Amount of the Revolving L/C Obligations would exceed the Revolving L/C Sublimit; provided, further, that the Dollar Equivalent of the aggregate face amount of Revolving Letters of Credit issued by a Revolving L/C Issuer shall not exceed such Revolving L/C Issuer’s Revolving L/C Issuer Sublimit.

Subject to the terms and conditions set forth herein, the Term L/C Issuers agree, (1) from time to time on any Business Day during the period from the Closing Date until the Term L/C Expiration Date, to issue Term L/C Facility Letters of Credit for the account of the Borrower (it being understood and agreed that subject to the other terms herein, the Borrower may obtain for its account Term L/C Facility Letters of Credit on behalf of the Parent Guarantor or any of its Affiliates), and to amend or renew Term L/C Facility Letters of Credit previously issued by it, in accordance with Section 2.03(b), and (2) to honor drafts under the Term L/C Facility Letters of Credit; provided that no Term L/C Issuer shall be obligated to make any Term L/C Credit Extension with respect to any Term L/C Facility Letter of Credit if as of the date of such Term L/C Credit Extension (x) the Outstanding Amount of all Term L/C Facility Obligations would exceed the aggregate Term L/C Issuer Commitments; (y) the Outstanding Amount of Term L/C Facility Obligations in respect of Term L/C Facility Letters of Credit issued by such Term L/C Issuer would exceed such Term L/C Issuer’s Term L/C Issuer Sublimit; or (z) the Term L/C Collateral Account Balance shall be less than the Required Term L/C Collateral Account Balance; provided, further, that the Dollar Equivalent of the aggregate face amount of Term L/C Facility Letters of Credit issued by a Term L/C Issuer shall not exceed such Term L/C Issuer’s Term L/C Issuer Sublimit.

Within the foregoing limits, and subject to the terms and conditions hereof, the Borrower’s ability to obtain Letters of Credit shall be fully revolving, and accordingly the Borrower may, during the foregoing period, obtain Letters of Credit to replace Letters of Credit that have expired or that have been drawn upon and reimbursed. All Existing Revolving Letters of Credit shall be deemed to have been issued pursuant hereto, and from and after the Closing Date shall be Revolving Letters of Credit and shall be subject to and governed by the terms and conditions hereof.

(ii) No L/C Issuer shall be under any obligation to issue any Letter of Credit if:

(A) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain such L/C Issuer from issuing such Letter of Credit, or any Law applicable to such L/C Issuer or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over such L/C Issuer shall prohibit, or request that such L/C Issuer refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon such L/C Issuer with respect to such Letter of Credit any restriction, reserve or capital requirement (for which such L/C Issuer is not otherwise compensated hereunder) not in effect on the Closing Date, or shall impose upon such L/C Issuer any unreimbursed loss, cost or expense which was not applicable on the Closing Date and which such L/C Issuer in good ▇▇▇▇▇ ▇▇▇▇▇ material to it;

(B) the expiry date of such requested Letter of Credit would occur after the earlier of (1) the first anniversary of its date of issuance and (2) in the case of a Revolving Letter of Credit, the Revolving Letter of Credit Expiration Date and in the case of a Term L/C Facility Letter of Credit, the Term L/C Expiration Date; provided that, notwithstanding the foregoing, any Revolving Letter of Credit issued or extended no later than 90 days prior to the Revolving Credit Termination Date may have an expiration date of up to nine months after the Revolving Credit Termination Date so long as the Borrower has provided Cash Collateral in an amount equal to the undrawn amount of such Revolving Letter of Credit on or before the date of such issuance or extension and otherwise in accordance with Section 2.03(g); or

(iii) No L/C Issuer shall be under any obligation to amend any Letter of Credit in any way (whether or not such amendment increases the amount of the applicable Letter of Credit) (A) at any time on or after, in the case of a Revolving Letter of Credit, the Revolving Credit Termination Date or, in the case of a Term L/C Facility Letter of Credit, the Term L/C Facility Term Loan Maturity Date, or (B) if the beneficiary of such Letter of Credit does not accept the proposed amendment to such Letter of Credit. In addition, and without limiting the terms of the first sentence of this Section 2.03(a)(iii), no L/C Issuer shall be under any obligation to amend any Letter of Credit to increase the amount thereof if such L/C Issuer would have no obligation at such time to issue such Letter of Credit in its amended form under the terms hereof by reason of the provisions of Section 2.03(a)(i), Section 2.03(a)(ii), Section 4.02 or otherwise.

(iv) Any L/C Issuer may be replaced at any time by written agreement among the Borrower, the Administrative Agents, the replaced L/C Issuer and the applicable successor L/C Issuer. The Payment Agent shall notify the Lenders of any such replacement of an L/C Issuer. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced L/C Issuer pursuant to Sections 2.03(i) and (j). From and after the effective date of any such replacement, (i) such successor L/C Issuer shall have all the rights and obligations of the replaced L/C Issuer under this Agreement with respect to Revolving Letters of Credit or Term L/C Facility Letters of Credit, as the case may be, otherwise to be issued thereafter by such replaced LC Issuer and (ii) references herein to the term “L/C Issuer”, “Revolving L/C Issuer” or “Term L/C Issuer”, shall be deemed to refer, as the case may be, to (x) such successor or any previous or other Revolving L/C Issuer or Term L/C Issuer or (y) such successor and all previous and other Revolving L/C Issuers and/or Term L/C Issuers, as the context shall require. After the replacement of an L/C Issuer hereunder, the replaced L/C Issuer shall remain a party hereto and shall continue to have all the rights and obligations of a Revolving L/C Issuer or Term L/C Issuer, as the case may be, under this Agreement with respect to Revolving Letters of Credit or Term L/C Facility Letters of Credit, as the case may be, issued by it prior to such replacement, but shall not be required to issue additional Revolving Letters of Credit or Term L/C Facility Letters of Credit, as the case may be.

(b) Procedures for Issuance and Amendment of Letters of Credit; Auto-Renewal Letters of Credit.

(i) Each Letter of Credit shall be issued or amended, as the case may be, upon the request of the Borrower delivered to the relevant L/C Issuer (with a copy to the Payment Agent) in the form of a Letter of Credit Application. Such Letter of Credit Application must be received by such L/C Issuer and the Payment Agent not later than 12:00 noon (eastern time) at least two Business Days (or such later date and time as such L/C Issuer may agree in a particular instance in its sole discretion) prior to the proposed issuance date or date of amendment, as the case may be. In the case of a request for an initial issuance of a Letter of Credit, such Letter of Credit Application shall specify in form and detail reasonably satisfactory to such L/C Issuer: (A) whether such Letter of Credit is to be a Revolving Letter of Credit or a Term L/C Facility Letter of Credit, (B) the proposed issuance date of the requested Letter of Credit (which shall be a Business Day); (C) the amount thereof; (D) the expiry date thereof; (E) in the case of a Revolving Letter of Credit, the currency (which may be Dollars, Canadian Dollars, Pounds Sterling or Euros), and in the case of a Term L/C Facility Letter of Credit, whether such Term L/C Facility Letter of Credit will be denominated in Dollars or will be the TransCanada Term L/C Facility Letter of Credit (which shall be denominated in Canadian Dollars); (F) the name and address of the beneficiary thereof; (G) the account party or parties thereof; (H) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; and (I) the transactions or obligations to be supported thereby. In the case of a request for an amendment of any outstanding Letter of Credit, such Letter of Credit Application shall specify in form and detail reasonably satisfactory to the relevant L/C Issuer (1) the Letter of Credit to be amended; (2) the proposed date of amendment thereof (which shall be a Business Day); (3) the nature of the proposed amendment; and (4) such other matters consistent with the items set forth in clauses (A)-(I) in the preceding sentence as such L/C Issuer may reasonably require. Renewals of, and amendments to increase the available amount under, any outstanding Letters of Credit will be effectuated by the applicable L/C Issuer within one Business Day of the applicable L/C Issuer’s receipt of the Borrower’s written request for such renewal or increase. The Borrower’s request to reduce the effective face amount of any Letter of Credit shall be effective upon the applicable L/C Issuer’s receipt of a written consent of the beneficiary of such Letter of Credit consenting to such reduction.

(ii) Promptly after receipt of any Letter of Credit Application, the relevant L/C Issuer will confirm with the Payment Agent (by telephone or in writing) that the Payment Agent has received a copy of such Letter of Credit Application from the Borrower and, if not, such L/C Issuer will provide the Payment Agent with a copy thereof. Upon receipt by such L/C Issuer of confirmation from the Payment Agent that the requested issuance or amendment is permitted in accordance with the terms hereof, then, subject to the terms and conditions hereof, such L/C Issuer shall, on the requested date, issue a Letter of Credit for the account of the Borrower or enter into the applicable amendment, as the case may be, in each case in accordance with such L/C Issuer’s usual and customary business practices. Immediately upon the issuance of each Revolving Letter of Credit, each Revolving Credit Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the relevant Revolving L/C Issuer a risk participation in such Revolving Letter of Credit in an amount equal to the product of such Revolving Credit Lender’s Pro Rata Share times the amount of such Revolving Letter of Credit. No L/C Issuer shall be obligated to make any independent determination as to whether the requested issuance or amendment is permitted in

accordance with the terms hereof, and, unless and until such L/C Issuer receives such confirmation from the Payment Agent, such L/C Issuer shall have no obligation to issue the requested Letter of Credit.

(iii) If the Borrower so requests in any applicable Letter of Credit Application, any L/C Issuer may, in its sole and absolute discretion, agree to issue an Auto-Renewal Letter of Credit. Unless otherwise directed by such L/C Issuer, the Borrower shall not be required to make a specific request to such L/C Issuer for any such renewal. Once an Auto-Renewal Letter of Credit has been issued, the Borrower and, in the case of any Revolving Letter of Credit, the Revolving Credit Lenders, shall be deemed to have authorized (but may not require) such L/C Issuer to permit the renewal of such Letter of Credit at any time to an expiry date not later than, in the case of any Revolving Letter of Credit, the Revolving Letter of Credit Expiration Date and, in the case of any Term L/C Facility Letter of Credit, the Term L/C Expiration Date; provided that (A) such L/C Issuer may give a notice of non-renewal and thereby prevent the renewal of an Auto-Renewal Letter of Credit if such L/C Issuer has determined at any time within 30 calendar days prior to the Nonrenewal Notice Date of such Auto-Renewal Letter of Credit that it would have no obligation at such time to issue such Letter of Credit in its renewed form under the terms hereof (by reason of the provisions of Section 2.03(a)(i), Section 2.03(a)(ii), Section 2.03(a)(iii) or otherwise), and (B) such L/C Issuer shall not permit any such renewal if it has received notice (which may be by telephone, if immediately confirmed in writing, or in writing) on or before the day that is ten days before the Nonrenewal Notice Date from the Payment Agent or the Borrower that one or more of the applicable conditions specified in Section 2.03(a)(i) is not then satisfied; and provided, further, that, notwithstanding the foregoing, any Revolving Letter of Credit so renewed no later than 90 days prior to the Revolving Credit Termination Date may have an expiration date of up to nine months after the Revolving Credit Termination Date so long as the Borrower has provided Cash Collateral in an amount equal to the undrawn amount of such Letter of Credit on or before the date of such renewal in accordance with Section 2.03(g).

(iv) Promptly after its delivery of any Letter of Credit or any amendment to a Letter of Credit to an advising bank with respect thereto or to the beneficiary thereof, the relevant L/C Issuer will also deliver to the Borrower and the Payment Agent a true and complete copy of such Letter of Credit or amendment.

(i) Upon receipt from the beneficiary of any Revolving Letter of Credit of any notice of a drawing under such Letter of Credit, the relevant Revolving L/C Issuer shall promptly notify the Borrower and the Payment Agent thereof (which may be telephonic, promptly confirmed by telecopy). Not later than 12:00 p.m., (eastern time), on the Honor Date, the Borrower may (but shall not be required to) reimburse such Revolving L/C Issuer through the Payment Agent in an amount equal to the Dollar Equivalent of such drawing. If the Borrower does not so reimburse the relevant Revolving L/C Issuer on the date necessary to settle the obligations of such Revolving L/C Issuer under any draft drawn or demand made under such Revolving Letter of Credit, the Payment Agent shall promptly notify each Revolving Credit Lender of the Honor Date, the Dollar Equivalent of the unreimbursed drawing (the “Revolving Unreimbursed Amount”), and the amount of such Revolving Credit Lender’s Pro Rata Share thereof. In

such event, the Revolving Unreimbursed Amount shall automatically be converted (unless the Borrower is in Default under Section 8.01(f) or (g)) to a Revolving Credit Borrowing of Base Rate Loans to be disbursed on the Honor Date in an amount equal to the Dollar Equivalent of the Revolving Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.02 for the principal amount of Base Rate Loans and without regard to whether the conditions in Section 4.02 are then satisfied.

Upon receipt from the beneficiary of any Term L/C Facility Letter of Credit of any notice of a drawing under such Letter of Credit, the relevant Term L/C Issuer shall promptly notify the Borrower and the Payment Agent thereof (which may be telephonic, promptly confirmed by telecopy). The Borrower shall be required to reimburse such Term L/C Issuer through the Payment Agent in an amount equal to the Dollar Equivalent of such drawing not later than 1:00 p.m., (eastern time) on the Honor Date, if the Borrower shall have received such notice prior to 11:00 a.m. (eastern time) on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 1:00 p.m. (eastern time) on the next Business Day; provided that unless the Borrower shall reimburse such Term L/C Issuer by 1:00 p.m. (eastern time) on the same day on which such drawing is made, the unpaid amount thereof shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin, for each day commencing on the date the drawing is made until the date that the Borrower pays the Payment Agent for the account of such Term L/C Issuer the Dollar Equivalent of the amount of such drawing. If the Borrower does not so reimburse the relevant Term L/C Issuer at or prior to the time for payment specified above in respect of such drawing under such Term L/C Facility Letter of Credit, the Payment Agent shall promptly cause the amounts on deposit in the Term L/C Collateral Account to be applied to repay in full such amounts (such amounts, including accrued interest, the “Term L/C Facility Unreimbursed Amount” and, together with the Revolving Unreimbursed Amount, the “Unreimbursed Amount”) and the Term L/C Facility shall be automatically and permanently reduced by the Term L/C Facility Unreimbursed Amount in accordance with Section 2.05(c).

Any notice given by any L/C Issuer or the Payment Agent pursuant to this Section 2.03(c)(i) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

(ii) Each Revolving Credit Lender (including the Revolving Credit Lender acting as Revolving L/C Issuer) shall upon any notice pursuant to Section 2.03(c)(i) make funds available to the Payment Agent for the account of the relevant Revolving L/C Issuer at the Payment Agent’s Office in an amount equal to its Pro Rata Share of the Revolving Unreimbursed Amount not later than 1:00 p.m. (eastern time) on the Business Day specified in such notice by the Payment Agent, whereupon, subject to the provisions of Section 2.03(c)(iii), each Revolving Credit Lender that so makes funds available shall be deemed to have made a Base Rate Loan to the Borrower in such amount. The Payment Agent shall remit the funds so received to such Revolving L/C Issuer.

(iii) Such Base Rate Loan shall be made as of the date of such settlement of such Revolving Letter of Credit. The proceeds of such Base Rate Loan shall be paid by the Revolving Credit Lenders to the Payment Agent for payment to the relevant Revolving L/C Issuer of such Revolving Letter of Credit (and the Payment Agent shall promptly pay such proceeds to such Revolving L/C Issuer) to reimburse such Revolving

L/C Issuer of such Revolving Letter of Credit for each Revolving Lender’s Pro Rata Share of the Dollar Equivalent of the amount actually disbursed by such Revolving L/C Issuer of such Revolving Letter of Credit pursuant to such draft or demand. In the event that any Revolving L/C Issuer of a Revolving Letter of Credit makes the Draw Amount available to the beneficiary of such Revolving Letter of Credit and the Dollar Equivalent of such amount made available by the Revolving Lenders to the Payment Agent for payment to such Revolving L/C Issuer is not sufficient to enable such Revolving L/C Issuer to obtain Alternative Currency equal to the entire Draw Amount, the Borrower shall pay the Payment Agent on demand for the benefit of such Revolving L/C Issuer an amount equal to the Dollar Equivalent required to enable such Revolving L/C Issuer to obtain Alternative Currency equal to the Draw Amount, but any shortfall shall be immediately converted to an additional Borrowing of Base Rate Loans made by the Revolving Credit Lenders to the Borrower to the extent the Borrower does not immediately make such payment, and such Revolving L/C Issuer shall be reimbursed therefrom. With respect to any Revolving Unreimbursed Amount that is not fully refinanced by a Revolving Credit Borrowing of Base Rate Loans because the Borrower is in Default under Section 8.01(f) or (g) or for any other reason, the Borrower shall be deemed to have incurred from the relevant Revolving L/C Issuer a Revolving L/C Borrowing in the amount of the Revolving Unreimbursed Amount that is not so refinanced, which Revolving L/C Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the Default Rate. In such event, each Revolving Credit Lender’s payment to the Payment Agent for the account of such Revolving L/C Issuer pursuant to Section 2.03(c)(ii) shall be deemed payment in respect of its participation in such Revolving L/C Borrowing and shall constitute a Revolving L/C Advance from such Lender in satisfaction of its participation obligation under this Section 2.03.

(iv) Until each Revolving Credit Lender funds its Revolving Credit Loan or Revolving L/C Advance pursuant to this Section 2.03(c) to reimburse any Revolving L/C Issuer for any amount drawn under any Revolving Letter of Credit, interest in respect of such Revolving Lender’s Pro Rata Share of such amount shall be solely for the account of such Revolving L/C Issuer.

(v) Each Revolving Credit Lender’s obligation to make Revolving Credit Loans or Revolving L/C Advances to reimburse any Revolving L/C Issuer for amounts drawn under Revolving Letters of Credit, as contemplated by this Section 2.03(c), shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Revolving Credit Lender may have against such Revolving L/C Issuer, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided that each Revolving Credit Lender’s obligation to make Revolving Credit Loans (but not its obligation to make Revolving L/C Advances) pursuant to this Section 2.03(c) is subject to the Borrower not being in Default under Section 8.01(f) or (g). No such making of a Revolving L/C Advance shall relieve or otherwise impair the obligation of the Borrower to reimburse such Revolving L/C Issuer for the amount of any payment made by such Revolving L/C Issuer under any Revolving Letter of Credit, together with interest as provided herein.

(vi) If any Revolving Credit Lender fails to make available to the Payment Agent for the account of any Revolving L/C Issuer any amount required to be paid by

such Revolving Credit Lender pursuant to the foregoing provisions of this Section 2.03(c) by the time specified in Section 2.03(c)(ii), such Revolving L/C Issuer shall be entitled to recover from such Revolving Credit Lender (acting through the Payment Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to such Revolving L/C Issuer at a rate per annum equal to the Federal Funds Rate from time to time in effect for the first three Business Days and, thereafter, at a rate of interest equal to the Base Rate. A certificate of the relevant Revolving L/C Issuer submitted to any Revolving Credit Lender (through the Payment Agent) with respect to any amounts owing under this Section 2.03(c)(vi) shall be conclusive absent manifest error.

(vii) If at any time a distribution is to be made by the Payment Agent to any Revolving Credit Lender and such Revolving Credit Lender has failed to make available to the Payment Agent for the account of the relevant Revolving L/C Issuer any amount required to be paid by such Revolving Credit Lender pursuant to the foregoing provisions of this Section 2.03(c), the Payment Agent shall pay such distribution to such Revolving L/C Issuer, to the extent of such unpaid amount together with any interest thereon accrued pursuant to Section 2.03(c)(vi).

(d) Repayment of Participations in Revolving Letters of Credit.

(i) At any time after any Revolving L/C Issuer has made a payment under any Revolving Letter of Credit and has received from any Revolving Credit Lender such Revolving Credit Lender’s Revolving L/C Advance in respect of such payment in accordance with Section 2.03(c), if the Payment Agent receives for the account of such Revolving L/C Issuer any payment in respect of the related Revolving Unreimbursed Amount or interest thereon (whether directly from the Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the Payment Agent), the Payment Agent will distribute to such Revolving Credit Lender its Pro Rata Share thereof (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Revolving Credit Lender’s Revolving L/C Advance was outstanding) in the same funds as those received by the Payment Agent.

(ii) If any payment received by the Payment Agent for the account of any Revolving L/C Issuer pursuant to Section 2.03(c)(i) is required to be returned under any of the circumstances described in Section 11.06 (including pursuant to any settlement entered into by such Revolving L/C Issuer in its discretion), each Revolving Credit Lender shall pay to the Payment Agent for the account of such Revolving L/C Issuer its Pro Rata Share thereof on demand of the Payment Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Revolving Credit Lender, at a rate per annum equal to the Federal Funds Rate from time to time in effect for the first three days and, thereafter, at a rate of interest equal to the Base Rate.

(e) Obligations Absolute. The obligation of the Borrower to reimburse any relevant L/C Issuer for each drawing under each Letter of Credit and (without duplication, in the case of any Revolving Letter of Credit) to repay each Revolving L/C Borrowing shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:

(i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other agreement or instrument relating thereto;

(ii) the existence of any claim, counterclaim, setoff, defense or other right that the Borrower may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), such L/C Issuer or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction;

(iii) any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit;

(iv) any payment by such L/C Issuer under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or any payment made by such L/C Issuer under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of such Letter of Credit, including any arising in connection with any proceeding under any Debtor Relief Law;

(v) any exchange, release or nonperfection of any Collateral, or any release or amendment or waiver of or consent to departure from the Guaranty or any other guarantee, for all or any of the Obligations of the Borrower in respect of such Letter of Credit; or

(vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Borrower, except as otherwise provided in clause (f) of this Section 2.03.

The Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with the Borrower’s instructions or other irregularity, the Borrower will immediately notify the relevant L/C Issuer. The Borrower shall be conclusively deemed to have waived any such claim against such L/C Issuer and its correspondents unless such notice is given as aforesaid.

(f) Role of L/C Issuer. The Borrower and, in the case of Revolving Letters of Credit, the Revolving Credit Lenders agree that, in paying any drawing under a Letter of Credit, no L/C Issuer shall have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. None of any L/C Issuer, any Agent-Related Person nor any of the respective correspondents, participants or assignees of any L/C Issuer shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Required Lenders, as applicable; (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Letter of Credit Application. The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided that this assumption is not intended to, and shall not, preclude the Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of any L/C Issuer, any

Agent-Related Person, nor any of the respective correspondents, participants or assignees of any L/C Issuer, shall be liable or responsible for any of the matters described in clauses (i) through (iv) of Section 2.03(e); provided that anything in such clauses to the contrary notwithstanding, the Borrower may have a claim against an L/C Issuer, and such L/C Issuer may be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by the Borrower which the Borrower proves were caused by such L/C Issuer’s willful misconduct or gross negligence or such L/C Issuer’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit AND THE PARENT GUARANTOR AND THE BORROWER FOR THEMSELVES AND THEIR SUBSIDIARIES HEREBY WAIVE AND RELINQUISH ANY AND ALL CLAIMS THEY MAY HAVE FOR INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES AND FOR DIRECT DAMAGES RESULTING FROM NEGLIGENCE BY ANY L/C ISSUER WHICH DOES NOT RISE TO THE LEVEL OF GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. In furtherance and not in limitation of the foregoing, any L/C Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and such L/C Issuer shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

(g) Cash Collateral for Revolving Letters of Credit. Upon the request of the Payment Agent or any Revolving L/C Issuer to the Borrower, if, as of the Revolving Letter of Credit Expiration Date, any Revolving Letter of Credit may for any reason remain outstanding and partially or wholly undrawn, the Borrower shall immediately Cash Collateralize the then Outstanding Amount of all Revolving L/C Obligations (in an amount equal to 103% of the Dollar Equivalent of such Outstanding Amount determined as of the Revolving Letter of Credit Expiration Date). As required pursuant to Section 2.03(a)(ii) or 2.03(b)(iii), the Borrower shall immediately Cash Collateralize the relevant Revolving Letter(s) of Credit in the amount specified therein. The Borrower hereby grants to the Collateral Agent, for the benefit of the Revolving L/C Issuers and the Revolving Credit Lenders, a security interest in all such cash, deposit accounts and all balances therein and all proceeds of the foregoing. Cash Collateral for the Revolving L/C Obligations shall be maintained in a Cash Collateral Account (other than the Term L/C Collateral Account). If at any time the Collateral Agent determines that any such Cash Collateral is subject to any right or claim of any Person other than the Collateral Agent or that the total amount of such funds is less than the aggregate Outstanding Amount of all Revolving L/C Obligations that are required to be Cash Collateralized at such time, the Borrower will, forthwith upon demand by the Collateral Agent, pay to the Collateral Agent, as additional funds to be deposited and held in such Cash Collateral Account, an amount equal to the excess of (a) 103% of the Dollar Equivalent of such aggregate Outstanding Amount over (b) the total amount of funds, if any, then held as Cash Collateral that the Collateral Agent determines to be free and clear of any such right and claim. Upon the drawing of any Revolving Letter of Credit for which funds are on deposit as Cash Collateral for the Revolving L/C Obligations, such funds shall be applied, to the extent permitted under applicable law, to reimburse the relevant Revolving L/C Issuers. So long as no Event of Default shall have occurred and be continuing, upon payment, expiration or termination of a Revolving Letter of Credit that was Cash Collateralized, applicable amounts on deposit in Cash Collateral Accounts (other than the Term L/C Collateral Account) shall be promptly returned to the Borrower.

(h) Applicability of ISP98 and UCP. Unless otherwise expressly agreed by the relevant L/C Issuer and the Borrower when a Letter of Credit is issued (including any such agreement applicable to an Existing Revolving Letter of Credit), (i) the rules of the “International Standby Practices 1998” published by the Institute of International Banking Law & Practice (or such later version thereof as may be in effect at the time of issuance) shall apply to each standby Letter of Credit, and (ii) the rules of the

Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce (the “ICC”) at the time of issuance shall apply to each commercial Letter of Credit, and in each case to the extent not inconsistent with the above referred rules, the laws of the State of New York shall apply to each Letter of Credit.

(i) Letter of Credit Fees. In the case of Revolving Letters of Credit, the Borrower shall pay to the Payment Agent for the account of each Revolving Credit Lender in accordance with its Pro Rata Share a Letter of Credit fee for each Revolving Letter of Credit equal to the Applicable Margin per annum for Eurodollar Rate Loans under the Revolving Credit Facility times the daily maximum amount available to be drawn under such Letter of Credit, provided that for purposes of this Section 2.03(i), the Dollar Equivalent of each Revolving Letter of Credit in an Alternative Currency will be deemed to be, on any day (i) during the month a Revolving Letter of Credit is issued or renewed, the Dollar Equivalent on such date of issuance or renewal or (ii) in any month subsequent to the month of issuance or renewal, the Dollar Equivalent on the first Business Day of such subsequent month, in each case from and including the date issued to and including the date of its expiration or earlier termination. Such letter of credit fees shall be computed on a quarterly basis in arrears. Such letter of credit fees shall accrue and be due and payable on the fifth Business Day following receipt by the Borrower of an invoice for such Letter of Credit fees owing with respect to the prior calendar quarter commencing with the first such date to occur after the issuance of such Revolving Letter of Credit, and on the Revolving Credit Termination Date.

(j) Fronting Fee and Documentary and Processing Charges Payable to L/C Issuer. The Borrower hereby agrees to pay to the relevant L/C Issuer solely for its benefit, (i) in the case of Letters of Credit that are standby Letters of Credit a Letter of Credit fronting fee equal to a per annum amount (calculated for the actual number of days elapsed on the basis of a year consisting of 365, or when appropriate 366, days) as agreed between the Borrower and such L/C Issuer on the daily average available amount under each such Letter of Credit issued, increased or extended by such L/C Issuer from and including the date issued, increased or extended to and including the date of its expiration or earlier termination, (ii) in the case of Letters of Credit that are commercial Letters of Credit a Letter of Credit fronting fee equal to a per annum amount (calculated for the actual number of days elapsed on the basis of a year consisting of 365, or when appropriate 366, days) as agreed between the Borrower and such L/C Issuer on the daily average available amount under each such Letter of Credit issued, increased or extended by the such L/C Issuer from and including the date issued, increased or extended to and including the date of its expiration or earlier termination, and (iii) a fee for each issuance, amendment or renewal of, and for each negotiation of a draft drawn under, a Letter of Credit issued, increased or extended by such L/C Issuer in the amount customarily charged by such L/C Issuer from time to time or such other amount that may be agreed to in writing from time to time by such L/C Issuer and the Borrower, provided that for purposes of this Section 2.03(j), the Dollar Equivalent of each Letter of Credit in an Alternative Currency will be deemed to be, on any day (i) during the month the Letter of Credit was issued or renewed, the Dollar Equivalent on the date of issuance or renewal of such Letter of Credit or (ii) in any month subsequent to the month of issuance or renewal, the Dollar Equivalent on the first Business Day of such subsequent month, in each case from and including the date issued to and including the date of its expiration or earlier termination. The Borrower shall pay to the Payment Agent on the fifth Business Day following receipt by the Borrower of an invoice for such fees owing with respect to the prior calendar quarter, the Letter of Credit fronting fee due with respect to each outstanding Letter of Credit commencing on the first such date to occur after such Letter of Credit is issued, increased or extended and, in the case of Letters of Credit, on the Revolving Credit Termination Date and, in the case of the Term L/C Facility Letters of Credit, the Term L/C Facility Term Loan Maturity Date. The Payment Agent shall promptly remit to the relevant L/C Issuer any Letter of Credit fronting fee due to such L/C Issuer after the Payment Agent’s receipt of such fee.

(k) Term L/C Collateral Account. On or prior to the Closing Date, the Borrower shall establish the Term L/C Collateral Account for the purpose of cash collateralizing the Borrower’s obligations to the Term L/C Issuers in respect of the Term L/C Facility Letters of Credit. On the Closing Date the proceeds of the Term L/C Facility Term Loans, together with other funds (if any) provided by the Borrower, shall be deposited into the Term L/C Collateral Account such that, and the Borrower agrees that at all times thereafter, and shall immediately cause additional funds to be deposited and held in the Term L/C Collateral Account from time to time in order that, the Term L/C Collateral Account Balance shall at least equal the Required Term L/C Collateral Account Balance. The Borrower hereby grants to the Collateral Agent, for the benefit of the Term L/C Issuers, a security interest in the Term L/C Collateral Account and all cash and balances therein and all proceeds of the foregoing, as security for the Term L/C Facility Obligations (and, in addition, grants a security interest therein, for the benefit of the Secured Parties as collateral security for the Secured Obligations, provided that amounts on deposit in the Term L/C Collateral Account shall be applied, first, to repay the Term L/C Facility Obligations and, then, all other Secured Obligations). Except as expressly provided herein or in any other Loan Document, no Person shall have the right to make any withdrawal from the Term L/C Collateral Account or to exercise any right or power with respect thereto; provided that at any time the Borrower shall fail to reimburse any Term L/C Issuer for any Term L/C Facility Unreimbursed Amounts in accordance with the terms of Section 2.03(c), the Borrower hereby absolutely, unconditionally and irrevocably agrees that the Collateral Agent shall be entitled to instruct the depositary bank (the “Depositary Bank”) of the Term L/C Collateral Account to withdraw therefrom and pay to the Payment Agent for account of such Term L/C Issuer amounts equal to such Term L/C Facility Unreimbursed Amounts. So long as no Event of Default shall have occurred and be continuing, upon at least three Business Days’ prior written notice to the Collateral Agent and the Payment Agent, the Borrower may, at any time and from time to time, request release of and payment to the Borrower of (and the Collateral Agent hereby agrees to instruct the Depositary Bank to release and pay to the Borrower) any amounts on deposit in the Term L/C Collateral Account in excess of the Required Term L/C Collateral Account Balance (provided that the Collateral Agent shall have received prior confirmation of the amount of such excess from the Payment Agent). In addition, the Collateral Agent hereby agrees to instruct the Depositary Bank to release and pay to the Borrower amounts (if any) remaining on deposit in the Term L/C Collateral Account after the termination of the Term L/C Facility and all Term L/C Facility Letters of Credit and the repayment in full of all outstanding Term L/C Facility Term Loans and Term L/C Facility Obligations.

(l) Conflict with Letter of Credit Application. In the event of any conflict between the terms hereof and the terms of any Letter of Credit Application, the terms hereof shall control.

2.04. Prepayments.

(a) Optional. The Borrower may, upon notice to the Payment Agent, at any time or from time to time voluntarily prepay Loans under either Facility in whole or in part without premium or penalty; provided that (i) such notice must be received by the Payment Agent not later than 12:00 noon (eastern time) on the date of prepayment of any Loans; (ii) any prepayment of Eurodollar Rate Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof; and (iii) any prepayment of Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof or, in each case, if less, the entire principal amount thereof then outstanding. Each such notice shall specify the date and amount of such prepayment and the Type(s) of Loans under the respective Facility to be prepaid. The Payment Agent will promptly notify the relevant Lenders of its receipt of each such notice, and of the amount of such Lender’s Pro Rata Share (if any) of such prepayment. If such notice is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied by all accrued interest thereon, together with any additional amounts required pursuant to Section 3.05. Each prepayment of the outstanding Loans

pursuant to this Section 2.04(a) shall be applied to the respective Facilities in the manner indicated by the Borrower and to the Lenders under such Facility in accordance with their respective Pro Rata Shares. Prepayments made pursuant to this Section 2.04(a) of the Term L/C Facility Term Loans shall be applied in accordance with Section 2.11(j).

(b) Mandatory.

(i) If for any reason the aggregate Outstanding Amount of all Revolving Credit Loans and Revolving L/C Obligations at any time exceeds the aggregate Revolving Credit Commitments then in effect, the Borrower shall immediately prepay the Revolving Credit Loans, reimburse Revolving Unreimbursed Amounts in respect of Revolving Letters of Credit and/or Cash Collateralize the Revolving L/C Obligations in an aggregate amount equal to such excess (or, in the case of the Cash Collateralization of Revolving L/C Obligations, 103% of the Dollar Equivalent of such excess) in accordance with the terms thereof. Once quarterly on such date as the Payment Agent shall determine and promptly upon the receipt by the Payment Agent of a Currency Valuation Notice (as defined below), if any Revolving L/C Obligations in respect of Revolving Letters of Credit denominated in an Alternative Currency shall then be outstanding, the Payment Agent shall determine the Dollar Equivalent of all such Revolving L/C Obligations as of such determination date (or, in the case of a Currency Valuation Notice received by the Payment Agent prior to 12:00 noon on a Business Day, on such Business Day or, in the case of a Currency Valuation Notice otherwise received, on the first Business Day after such Currency Valuation Notice is received). Upon making such determination, the Payment Agent shall promptly notify the Administrative Agents, the Lenders and the Borrower thereof. For purposes hereof, “Currency Valuation Notice” means a notice given by the Required Lenders to the Payment Agent stating that such notice is a “Currency Valuation Notice” and requesting that the Payment Agent determine the Dollar Equivalent of the Revolving L/C Obligations in respect of Revolving Letters of Credit denominated in Alternative Currencies. The Payment Agent shall not be required to make more than one determination pursuant to Currency Valuation Notices within any rolling three month period. If, on the date of such determination such Dollar Equivalent of such Revolving L/C Obligations in respect of Revolving Letters of Credit denominated in Alternative Currencies, when added to Revolving L/C Obligations in respect of Revolving Letters of Credit denominated in Dollars and Revolving Credit Loans, shall exceed the Revolving Credit Commitments, the Borrower shall prepay Revolving Credit Loans and/or Cash Collateralize Revolving L/C Obligations in the amount of such excess (or, in the case of Cash Collateralization of Revolving Letters of Credit, 103% of the Dollar Equivalent of such excess).

(ii) Subject to Section 2.04(b)(vi), if on any date the Borrower or any of its Restricted Subsidiaries shall receive Net Proceeds from any Asset Sales or the Parent Guarantor, the Borrower or any of their respective Restricted Subsidiaries shall receive Net Proceeds from any Recovery Event, then, unless a Reinvestment Notice shall be delivered in respect thereof, the Lenders’ Portion of such Net Proceeds shall be applied within five Business Days toward the prepayment of the Loans and the reduction of the Revolving Credit Commitments as set forth in Section 2.04(b)(v); provided that, notwithstanding the foregoing, (A) the cumulative Net Proceeds of Asset Sales that may be excluded from the foregoing requirement pursuant to one or more Reinvestment Notices shall not exceed $750,000,000 in the aggregate, (B) on each Reinvestment Prepayment Date, an amount equal to the Reinvestment Prepayment Amount with respect to the relevant Reinvestment Event shall be applied toward the prepayment of the Loans

and the reduction of the Revolving Credit Commitments as set forth in Section 2.04(b)(v), (C) the sale of the ▇▇▇▇▇▇▇ Facility shall not be permitted to be subject to any Reinvestment Notice and (D) any Net Proceeds of any Asset Sale or Recovery Event subject to a Reinvestment Notice shall be deposited into a Designated Account (as defined in the Shared Security Agreement) that is subject to an Account Control Agreement (as defined in the Shared Security Agreement) until the use or application of such Net Proceeds (it being understood that in the event the Parent Guarantor or any of its Restricted Subsidiaries shall receive any Net Proceeds of any Recovery Event, the Parent Guarantor shall forthwith cause such Net Proceeds to be paid or otherwise made available to the Borrower or the Restricted Subsidiary thereof that incurred the underlying loss).

(iii) Subject to Section 2.04(b)(vi), if on any date the Borrower or any of its Restricted Subsidiaries shall receive Net Proceeds from any Subject Indebtedness, then such Net Proceeds shall be applied within five Business Days toward the prepayment of the Loans and the reduction of the Revolving Credit Commitments as set forth in Section 2.04(b)(v).

(iv) Subject to Section 2.04(b)(vi), no later than ten days following the earlier of (i) the applicable deadline for filing the annual financial statements of the Borrower and its Subsidiaries with the SEC (without giving effect to any extension thereof that is specific to the Borrower) for each fiscal year of the Borrower, commencing with the fiscal year ending on December 31, 2007, and (ii) the date on which the financial statements with respect to such period are delivered pursuant to Section 6.01(a), the Borrower shall prepay outstanding Loans and reduce the Revolving Credit Commitments as set forth in Section 2.04(b)(v), in an aggregate principal amount equal to (x) the Required ECF Prepayment Percentage of Excess Cash Flow for the fiscal year then ended minus (y) the aggregate amount of any voluntary prepayments of Term L/C Facility Term Loans made pursuant to Section 2.04(a) during such fiscal year.

(v) Prepayments made pursuant to this Section 2.04(b) shall be applied, first, ratably to the prepayment of the Revolving Credit Loans (and, in the case of any Revolving Letters of Credit, to Cash Collateralize the Revolving L/C Obligations in respect thereof in an amount equal to 103% of the Dollar Equivalent of the amount thereof) and the Term L/C Facility Term Loans then outstanding (collectively, the “Outstanding Loans”), and, then after payment in full of the Outstanding Loans, to the permanent reduction of the unused amount of the Revolving Credit Commitments in accordance with Section 2.11(h); provided that, notwithstanding anything to the contrary in Section 2.04(b)(ii), Section 2.04(b)(iii), Section 2.04(b)(iv) or Section 2.11, the Borrower shall be permitted to Cash Collateralize, at 103% of the Dollar Equivalent of the amount otherwise required to be applied to the prepayment or reduction thereof, Revolving Credit Loans or unused Revolving Credit Commitments required to be so prepaid or reduced under Section 2.04(b)(ii), Section 2.04(b)(iii) or Section 2.04(b)(iv), and for purposes of Section 2.04(b)(vi), the amount of any applicable mandatory prepayment or commitment reduction, as the case may be, shall be reduced by the amount thereof so Cash Collateralized in accordance with this clause (v). Any such Cash Collateralization so elected by the Borrower shall be effected on the date otherwise required for the applicable prepayment or commitment reduction, as the case may be, specified in Section 2.04(b)(ii), (iii) or (iv), and the Borrower will give the Payment Agent telephonic notice on such date (promptly confirmed in writing) of any such Cash Collateralization.

(vi) Notwithstanding anything to the contrary in Section 2.04(b)(v) or Section 2.11, with respect to the amount of any mandatory prepayment described in Section 2.04(b)(ii), (iii) or (iv) (as the same shall have been reduced as described in clause (v) above) that is allocated to the Outstanding Loans (such amount, the “Prepayment Amount” and such amount with respect to the Term L/C Facility Term Loans, the “Term L/C Facility Prepayment Amount” and such amount with respect to the Revolving Credit Loans, the “Revolving Prepayment Amount”) or, as applicable, the permanent reduction of the unused amount of the Revolving Credit Commitments (such amount, as the same shall have been reduced as described in clause (v) above, the “Revolving Credit Reduction Amount”), the Borrower will, in lieu of applying such amount to the prepayment of the Outstanding Loans (or, in the case of any outstanding Revolving Letters of Credit, to Cash Collateralize the Revolving L/C Obligations in respect thereof in an amount equal to 103% of the Dollar Equivalent of the amount thereof) or, as applicable, the permanent reduction of the Revolving Credit Commitments as provided in clause (v) above, on the respective date specified in Section 2.04(b)(ii), (iii) or (iv) for such prepayment or permanent reduction, give the Payment Agent telephonic notice (promptly confirmed in writing) requesting that the Payment Agent prepare and provide to each Lender a notice (each, a “Prepayment Option Notice”) as described below (which shall specify the portion, if any, of the relevant Prepayment Amount or Revolving Credit Reduction Amount that the Borrower will Cash Collateralize pursuant to the proviso set forth in Section 2.04(b)(v)). As promptly as practicable after receiving such notice from the Borrower, the Payment Agent will send to each relevant Lender a Prepayment Option Notice, which shall be in the form of Exhibit I, and shall include an offer by the Borrower to, as applicable (A) prepay on the date (each a “Mandatory Prepayment Date”) that is 10 Business Days after the date of the Prepayment Option Notice, the Outstanding Loans of such Lender by an amount equal to the portion of the Prepayment Amount (i.e., the Revolving Prepayment Amount and/or the Term L/C Facility Prepayment Amount, as applicable) indicated in such Lender’s Prepayment Option Notice as being applicable to such Lender’s Outstanding Loans (i.e., the Revolving Credit Loans and/or the Term L/C Facility Term Loans, as applicable) and/or (B) as applicable, permanently reduce on the Mandatory Prepayment Date, the unused amount of the Revolving Credit Commitments of such Lender by an amount equal to the portion of the Revolving Credit Reduction Amount indicated in such Lender’s Prepayment Option Notice as being applicable to such Lender’s Revolving Credit Commitment. Each Lender shall notify the Payment Agent at least three Business Days prior to the Mandatory Prepayment Date of its decision to accept or reject such offer, and the Payment Agent shall notify the Borrower thereof no later than two Business Days prior to the Mandatory Prepayment Date. On the Mandatory Prepayment Date, (I) the Borrower shall pay to the Payment Agent for account of the relevant Lenders the aggregate amount necessary to prepay that portion of the Outstanding Loans in respect of which such Lenders have accepted prepayment as described above, (II) as applicable, the Revolving Credit Commitment of each Revolving Credit Lender who has accepted reduction as described above shall be permanently reduced to the extent set forth in its Prepayment Option Notice and (III) the Borrower shall be entitled to retain the Declined Proceeds, which Declined Proceeds shall be used by the Borrower for any purpose permitted or required under this Agreement.

(vii) Upon the drawing of any Revolving Letter of Credit which has been Cash Collateralized, such Cash Collateral shall be applied (without any further action by or notice to or from the Borrower or any other Loan Party) to reimburse the relevant Revolving L/C Issuers or the Revolving Credit Lenders, as applicable. For so long as no

Event of Default has occurred and is continuing, Cash Collateral shall be released to the Borrower (A) upon the termination or expiration of any such Cash Collateralized Letter of Credit, in an amount equal to the Cash Collateral pledged in respect of such Revolving Letter of Credit less any amounts used to reimburse the relevant Revolving L/C issuers and the Revolving Credit Lenders, as applicable, (B) upon the permanent reduction of Cash Collateralized Revolving Credit Commitments, in an amount equal to the Cash Collateral pledged in respect of such Revolving Credit Commitments and (C) upon the repayment of Cash Collateralized Revolving Credit Loans, in an amount equal to the Cash Collateral pledged in respect of such Revolving Credit Loans (provided that the associated Revolving Credit Commitments in respect of such Revolving Credit Loans shall have been permanently cancelled).

All prepayments under this Section 2.04 shall be made together with (i) accrued and unpaid interest to the date of such prepayment on the principal amount so prepaid and (ii) in the case of any such prepayment of a Eurodollar Rate Loan on a date other than the last day of an Interest Period therefor, any amounts owing in respect of such Eurodollar Rate Loan pursuant to Section 3.05. Notwithstanding any of the other provisions of Section 2.04(b), so long as no Default shall have occurred and be continuing, if any prepayment of Eurodollar Rate Loans is required to be made under Section 2.04(b) other than on the last day of the Interest Period therefor, the Borrower may, in its sole discretion, deposit the amount of any such prepayment otherwise required to be made thereunder into a Cash Collateral Account until the last day of such Interest Period, at which time the Payment Agent shall be authorized (without any further action by or notice to or from the Borrower or any other Loan Party) to apply such amount to the prepayment of such Loans in accordance with Section 2.04(b). Upon the occurrence of a Default, the Payment Agent shall also be authorized (without any further action by or notice to or from the Borrower or any other Loan Party) to apply such amount to the prepayment of such Loans in accordance with Section 2.04(b).

The Borrower may, upon notice to the Payment Agent, terminate the unused portion of the Revolving Credit Commitments or the Revolving L/C Sublimit, or from time to time permanently reduce the unused portion of the Revolving Credit Commitments or the Revolving L/C Sublimit; provided that (i) any such notice shall be received by the Payment Agent not later than 12:00 noon (eastern time) three Business Days prior to the date of termination or reduction, (ii) any such partial reduction shall be in a minimum aggregate amount of $5,000,000 or any whole multiple of $1,000,000 in excess thereof, (iii) the Borrower shall not terminate or reduce the unused portion of the Revolving Credit Commitments if, after giving effect thereto and to any concurrent prepayments hereunder, the Outstanding Amount of Revolving Credit Loans and Revolving L/C Obligations would exceed the aggregate Revolving Credit Commitments or if the Revolving L/C Sublimit would exceed the aggregate Revolving Credit Commitments and (iv) the Borrower shall not terminate or reduce the unused portion of the Revolving L/C Sublimit if, after giving effect thereto and to any concurrent prepayments hereunder, the Outstanding Amount of the Revolving L/C Obligations would exceed the Revolving L/C Sublimit. If after giving effect to any reduction or termination of unused Revolving Credit Commitments under this Section 2.05, the Revolving L/C Sublimit exceeds the aggregate Revolving Credit Commitments, the Revolving L/C Sublimit shall be automatically reduced by the amount of such excess.

The Borrower may, upon notice to the Payment Agent, terminate the unused portion of the Term L/C Issuer Commitments, or from time to time permanently reduce the unused portion of the Term L/C Issuer Commitments; provided that (i) any such notice shall be received by the Payment Agent not later than 12:00 noon (eastern time) three Business Days prior to the date of termination or reduction,

(ii) any such partial reduction shall be in a minimum aggregate amount of $5,000,000 or any whole multiple of $1,000,000 in excess thereof and (iii) the Borrower shall not terminate or reduce the Term L/C Issuer Commitments if, after giving effect thereto and to any concurrent prepayments hereunder, the Outstanding Amount of Term L/C Facility Obligations would exceed the aggregate Term L/C Issuer Commitment.

The Payment Agent will promptly notify the Revolving Credit Lenders of any termination or reduction of the unused portions of the Revolving L/C Sublimit or the unused Revolving Credit Commitments under this Section 2.05. Upon any reduction of unused Revolving Credit Commitments, the Revolving Credit Commitment of each Revolving Credit Lender shall be reduced by such Lender’s Pro Rata Share of the amount by which the Revolving Credit Commitments are reduced. All commitment fees accrued until the effective date of any termination of the Revolving Credit Commitments shall be paid on the fifth Business Day following receipt by the Borrower of an invoice on the first such date to occur after the effective date of such termination.

(c) Mandatory Commitment Reductions. The Term L/C Facility Commitments shall terminate upon the Term L/C Facility Borrowing on the Closing Date. The Term L/C Issuer Commitments shall be permanently reduced from time to time by the amount, if any, by which the amount of the Term L/C Issuer Commitments exceed the Maximum Percentage of the Term L/C Collateral Account Balance.

2.06. Repayment of Loans.

(a) The Borrower shall repay all outstanding Revolving Credit Loans on the Revolving Credit Termination Date.

(b) The Borrower shall repay all outstanding Term L/C Facility Term Loans on the Term L/C Facility Term Loan Maturity Date.

Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law.

2.08. Fees. In addition to certain fees described in Sections 2.03(i) and (j):

(a) Commitment Fee. The Borrower shall pay to the Payment Agent for the account of each Revolving Credit Lender in accordance with its Pro Rata Share, a commitment fee for the period from and including the Closing Date to but not including the last day of the Availability Period, computed at a rate equal to the Applicable Commitment Fee Rate times the actual daily amount by which the aggregate Revolving Credit Commitments exceed the sum of the Outstanding Amounts of the Revolving Credit Loans and the Revolving L/C Obligations; provided that any commitment fee accrued with respect to any of the Revolving Credit Commitments of a Defaulting Lender during the period prior to the time such Lender became a Defaulting Lender and unpaid at such time shall not be payable by the Borrower so long as such Lender shall be a Defaulting Lender except to the extent that such commitment fee shall otherwise have been due and payable by the Borrower prior to such time; and provided, further, that no commitment fee shall accrue on any of the Revolving Credit Commitments of a Defaulting Lender so long as such Lender shall be a Defaulting Lender.

The commitment fee shall be calculated quarterly in arrears.

(b) Other Fees. The Borrower shall pay to the Agents such fees as shall have been separately agreed upon in writing in the amounts and at the times so specified. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever.

2.09. Computation of Interest and Fees. All computations of interest for Base Rate Loans when the Base Rate is determined by Citibank’s “base rate” or fees shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of interest shall be made on the basis of a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365-day year). Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid, provided that any Loan that is repaid on the same day on which it is made shall, subject to Section 2.11(a), bear interest for one day. Each determination by the Payment Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error.

2.10. Evidence of Indebtedness.

(a) The Credit Extensions made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Payment Agent in the ordinary course of business. The accounts or records maintained by the Payment Agent and each Lender shall be conclusive absent manifest error of the amount of the Credit Extensions made by the Lenders to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Payment Agent in respect of such matters, the accounts and records of the Payment Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Payment Agent, the Borrower shall execute and deliver to such Lender (through the Payment Agent) a Note for each Facility under which such Lender holds Loans, which shall evidence such Lender’s Loans thereunder in addition to such accounts or records. Each Lender may attach schedules to its Note or Notes and endorse thereon the date, Type (if applicable), amount and maturity of its Loans and payments with respect thereto.

(b) In addition to the accounts and records referred to in Section 2.10(a), each Lender and the Payment Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Revolving Letters of Credit. In the event of any conflict between the accounts and records maintained by the Payment Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Payment Agent shall control in the absence of manifest error.

(c) Entries made in good faith by the Payment Agent in the Register pursuant to Section 2.10(b), and by each Lender in its account or accounts pursuant to Section 2.10(a), shall be prima facie evidence of the amount of principal and interest due and payable or to become due and payable from the Borrower to, in the case of the Register, each Lender and, in the case of such account or accounts, such Lender, under this Agreement and the other Loan Documents, absent manifest error; provided that the failure of the Payment Agent or such Lender to make an entry, or any finding that an entry is incorrect, in the Register or such account or accounts shall not limit or otherwise affect the obligations of the Borrower under this Agreement and the other Loan Documents.

2.11. Payments Generally.

(a) All payments to be made by the Borrower shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein, all payments by the Borrower hereunder shall be made to the Payment Agent, for the account of the respective Lenders to which such payment is owed, at the Payment Agent’s Office in Dollars and in immediately available funds not later than 2:00 p.m. (eastern time) on the date specified herein for such payment. The Payment Agent will promptly distribute to the Lenders such payment in like funds as received by wire transfer to such Lender’s Lending Office. All payments received by the Payment Agent after 2:00 p.m. (eastern time) shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue.

(b) If any payment to be made by the Borrower shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be; provided that, if such extension would cause payment of interest on or principal of Eurodollar Rate Loans to be made in the next succeeding calendar month, such payment shall be made on the immediately preceding Business Day.

(c) Unless the Borrower or any Lender has notified the Payment Agent, prior to the date any payment is required to be made by it to the Payment Agent hereunder, that the Borrower or such Lender, as the case may be, will not make such payment, the Payment Agent may assume that the Borrower or such Lender, as the case may be, has timely made such payment and may (but shall not be so required to), in reliance thereon, make available a corresponding amount to the Person entitled thereto. If and to the extent that such payment was not in fact made to the Payment Agent in immediately available funds, then:

(i) if the Borrower failed to make such payment, each Lender shall forthwith on demand repay to the Payment Agent the portion of such assumed payment that was made available to such Lender in immediately available funds, together with interest thereon in respect of each day from and including the date such amount was made available by the Payment Agent to such Lender to the date such amount is repaid to the Payment Agent in immediately available funds at the Federal Funds Rate from time to time in effect; and

(ii) if any Lender failed to make such payment, such Lender shall forthwith on demand pay to the Payment Agent the amount thereof in immediately available funds, together with interest thereon for the period from the date such amount was made available by the Payment Agent to the Borrower to the date such amount is recovered by the Payment Agent (the “Compensation Period”) at a rate per annum equal to the Federal Funds Rate from time to time in effect. If such Lender pays such amount to the Payment Agent, then such amount shall constitute such Lender’s Loan included in the applicable Borrowing. If such Lender does not pay such amount forthwith upon the Payment Agent’s demand therefor, the Payment Agent may make a demand therefor upon the Borrower, and the Borrower shall pay such amount to the Payment Agent, together with interest thereon for the Compensation Period at a rate per annum equal to the rate of interest applicable to the applicable Borrowing. Nothing herein shall be deemed to relieve any Lender from its obligation to fulfill its Commitment or to prejudice any rights which the Payment Agent or the Borrower may have against any Lender as a result of any default by such Lender hereunder.

A notice of the Payment Agent to any Lender or the Borrower with respect to any amount owing under this Section 2.11(c) shall be conclusive, absent manifest error.

(d) If any Lender makes available to the Payment Agent funds for any Loan to be made by such Lender as provided in the foregoing provisions of this Article II, and such funds are not made available to the Borrower by the Payment Agent because the conditions to the applicable Credit Extension set forth in Article IV are not satisfied or waived in accordance with the terms hereof, the Payment Agent shall return such funds (in like funds as received from such Lender) to such Lender, without interest.

(e) The obligations of the Lenders hereunder to make Loans and to fund participations in Letters of Credit are several and not joint. The failure of any Lender to make any Loan or to fund any such participation on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan or purchase its participation.

(f) Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan in any particular place or manner.

(g) Whenever any payment received by the Payment Agent under this Agreement or any of the other Loan Documents is insufficient to pay in full all amounts due and payable to the Agents and the Lenders under or in respect of this Agreement and the other Loan Documents on any date, such payment shall be distributed by the Payment Agent and applied by the Agents and the Lenders ratably in accordance with each Lender’s Pro Rata Share of all amounts then due and payable in respect of the Obligations. If the Payment Agent receives funds for application to the Obligations of the Loan Parties under or in respect of the Loan Documents under circumstances for which the Loan Documents do not specify the manner in which such funds are to be applied, the Payment Agent may, but shall not be obligated to, elect to distribute such funds to each of the Lenders in accordance with such Lender’s Pro Rata Share of the Total Outstandings at such time, in repayment or prepayment of such of the outstanding Loans or other Obligations then owing to such Lender.

(h) Each Borrowing by the Borrower from the Lenders under the Revolving Credit Facility, each payment by the Borrower on account of any commitment fee and any reduction of the Revolving Credit Commitments shall be made in accordance with the respective Pro Rata Shares of the

Revolving Credit Lenders under the Revolving Credit Facility (except as otherwise provided in Section 2.04(b)(iv)).

(i) Each payment (including each prepayment) by the Borrower on account of principal of and interest on the Revolving Credit Loans shall be made in accordance with the respective Pro Rata Shares of the Revolving Credit Lenders under the Revolving Credit Facility.

(j) Each payment (including each prepayment) by the Borrower on account of principal of and interest on the Term L/C Facility Term Loans shall be made in accordance with the respective Pro Rata Shares of the Term L/C Facility Lenders under the Term L/C Facility (except as otherwise provided in Section 2.04(b)(vi)).

2.12. Sharing of Payments. If, other than as expressly provided elsewhere herein, any Lender shall obtain on account of the Loans made by it, or the participations in Revolving L/C Obligations held by it, any payment (whether voluntary, involuntary, through the exercise of any right of setoff, or otherwise) in excess of its Pro Rata Share (or other share contemplated hereunder) thereof, such Lender shall immediately (a) notify the Payment Agent of such fact, and (b) purchase from the other Lenders under the Facility in respect of which such excess payment was made such participations in the Loans made by them and/or such subparticipations in the participations in Revolving L/C Obligations held by them as shall be necessary to cause such purchasing Lender to share the excess payment in respect of such Loans or such participations, as the case may be, pro rata with each of them; provided that if all or any portion of such excess payment is thereafter recovered from the purchasing Lender under any of the circumstances described in Section 11.06 (including pursuant to any settlement entered into by the purchasing Lender in its discretion), such purchase shall to that extent be rescinded and each such other Lender shall repay to the purchasing Lender the purchase price paid therefor, together with an amount equal to such paying Lender’s ratable share (according to the proportion of (i) the amount of such paying Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered, without further interest thereon. The Borrower agrees that any Lender so purchasing a participation from another Lender may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of setoff, but subject to Section 11.09) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. The Payment Agent will keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased under this Section 2.12 and will in each case notify the Lenders following any such purchases or repayments. Each Lender that purchases a participation pursuant to this Section 2.12 shall from and after such purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement with respect to the portion of the Obligations purchased to the same extent as though the purchasing Lender were the original owner of the Obligations purchased.

2.13. Incremental Revolving Credit Commitments.

(a) The Borrower may, by written notice to the Administrative Agents, elect to request, prior to the date 30 days prior to Revolving Credit Termination Date, an increase to the existing Revolving Credit Commitments (any such increase, the “New Revolving Credit Commitments”); provided that (i) the aggregate amount of New Revolving Credit Commitments shall not exceed $30,000,000 and (ii) the minimum amount of any such increase shall be $10,000,000 and multiples of $5,000,000 thereof. Each such notice shall specify the date (each, an “Increased Amount Date”) on which the Borrower proposes that the New Revolving Credit Commitments shall be effective, which shall be a date not less than five Business Days after the date on which such notice is delivered to the Payment Agent; provided that the Borrower shall first offer the Revolving Credit Lenders, on a pro rata basis, the opportunity to provide all of the New Revolving Credit Commitments prior to offering such opportunity

to any other Person that is an eligible assignee pursuant to Section 11.07(b); provided, further, that any Revolving Credit Lender offered or approached to provide all or a portion of the New Revolving Credit Commitments may elect or decline, in its sole discretion, to provide a New Revolving Credit Commitment. Such New Revolving Credit Commitments shall become effective, as of such Increased Amount Date; provided that (i) no Default shall exist on such Increased Amount Date before or after giving effect to such New Revolving Credit Commitments; (ii) both before and after giving effect to the making of any New Revolving Credit Loans, each of the conditions set forth in Section 4.02 shall be satisfied; (iii) the Borrower and its Subsidiaries shall be in pro forma compliance with each of the covenants set forth in Section 7.11 as of the last day of the most recently ended fiscal quarter for which financial statements are required to be delivered pursuant to Section 6.01(a), (b), (c) and (d) after giving effect to such New Revolving Credit Commitments; (iv) the New Revolving Credit Commitments shall be effected pursuant to one or more Joinder Agreements executed and delivered by each Lender with a New Revolving Credit Commitment (each, a “New Revolving Credit Lender”) and the Borrower (subject to the consents specified in clause (viii) below), and each of which shall be recorded in the Register; (v) the Borrower shall make any payments required pursuant to Section 3.05 in connection with the New Revolving Credit Commitments, as applicable; (vi) the Borrower shall deliver or cause to be delivered any legal opinions or other documents reasonably requested by the Payment Agent in connection with any such transaction; (vii) the requirements set forth in Section 6.13(b) shall have been satisfied; and (viii) the New Revolving Credit Lender in respect of a New Revolving Credit Commitment shall be approved by the Payment Agent and each Revolving L/C Issuer (such approval not to be unreasonably withheld or delayed). Each Joinder Agreement may, without the consent of any Lender (other than the Lender providing the New Revolving Credit Commitment pursuant thereto), effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the opinion of the Payment Agent, to reflect the relevant increase in the Revolving Credit Commitments contemplated in this Section 2.13.

(b) On any Increased Amount Date, subject to the satisfaction of the foregoing terms and conditions, (i) each of the Revolving Credit Lenders with Revolving Credit Commitments shall assign to each New Revolving Credit Lender and each of the New Revolving Credit Lenders shall purchase from each of the Lenders with Revolving Credit Commitments, at the principal amount thereof (together with accrued interest), such interests in the Revolving Credit Loans outstanding on such Increased Amount Date as shall be necessary in order that, after giving effect to all such assignments and purchases, such Revolving Credit Loans will be held by existing Lenders with Revolving Credit Loans and New Revolving Credit Lenders ratably in accordance with their Revolving Credit Commitments after giving effect to the addition of such New Revolving Credit Commitments to the Revolving Credit Commitments, (ii) each New Revolving Credit Commitment shall be deemed for all purposes a Revolving Credit Commitment and each loan made thereunder (a “New Revolving Credit Loan”) shall be deemed, for all purposes, a Revolving Credit Loan and (iii) each New Revolving Credit Lender shall become a Lender with respect to its New Revolving Credit Commitment and all matters relating thereto.

(c) The Payment Agent shall notify the Lenders promptly upon receipt of the Borrower’s notice of each Increased Amount Date and, in respect thereof, the respective interests in such Lender’s Revolving Credit Loans subject to the assignments contemplated by Section 2.13(b).

ARTICLE III

TAXES, YIELD PROTECTION AND ILLEGALITY

3.01. Taxes.

(a) Any and all payments by the Borrower to or for the account of any Agent or any Lender under any Loan Document shall be made free and clear of and without deduction for any and all

present or future withholding taxes, including duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and all liabilities with respect thereto, excluding, in the case of each Agent and each Lender, (i) taxes imposed on or measured by its income by the jurisdiction (or any political subdivision thereof) under the Laws of which such Agent or such Lender, as the case may be, is organized or in which it maintains a Lending Office and (ii) in the case of a Foreign Lender, any taxes imposed (other than taxes imposed because of a change in law (including a rate change), treaty, governmental rule or the application thereof, which change occurs after the date hereof, or in the case of an entity that becomes a Foreign Lender after the date hereof, after such entity becomes a Lender) by the United States of America by means of withholding at the source if and to the extent that such taxes shall be in effect and shall be applicable, under Laws in effect on the date hereof (or, with respect to any entity that becomes a Foreign Lender after the date hereof, on the date such entity becomes a Lender), on payments to be made to such Foreign Lender after taking into account any forms or certificates provided by such Foreign Lender under Section 11.15 (all such non-excluded taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required by any Laws to deduct any Taxes from or in respect of any sum payable under any Loan Document to any Agent or any Lender, (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 3.01), each of such Agent and such Lender 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 taxation authority or other authority in accordance with applicable Laws, and (D) within 30 days after the date of such payment, the Borrower shall furnish to such Agent or Lender (as the case may be) (which shall forward the same to such Lender) the original or a certified copy of a receipt evidencing payment thereof to the extent such a receipt is issued therefor, or other written proof of payment thereof that is reasonably satisfactory to the Payment Agent.

(b) In addition, the Borrower agrees to pay any and all present or future stamp, court or documentary taxes and any other excise or property, intangible, mortgage recording or similar taxes, charges or levies which arise from any payment made by the Borrower under any Loan Document or from the execution, delivery, performance, enforcement or registration of any Loan Document (hereinafter referred to as “Other Taxes”).

(c) The Borrower agrees to indemnify each Agent and each Lender for (i) the full amount of Taxes and Other Taxes (including any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section 3.01) paid by such Agent and such Lender and (ii) any liability (including additions to tax, penalties, interest and expenses) arising therefrom or with respect thereto, except as a result of the gross negligence or willful misconduct of such Agent or such Lender (as the case may be), in each case whether or not such Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. Payment under this Section 3.01(c) shall be made within 30 days after the date such Agent or such Lender makes a demand therefor.

3.02. Illegality. If any Lender determines that the introduction of or change in or in the interpretation of any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund Eurodollar Rate Loans, or to determine or charge interest rates based upon the Eurodollar Rate, then, on notice thereof by such Lender to the Borrower through the Payment Agent, any obligation of such Lender to make or continue Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans shall be suspended until such Lender notifies the Payment Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender (with a copy to the Payment Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of such Lender to Base Rate Loans, either on the last day of the Interest Period therefor, if

such Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Rate Loans. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted. Each Lender agrees to designate a different Lending Office if such designation will avoid the need for such notice and will not, in the good faith judgment of such Lender, otherwise be materially disadvantageous to such Lender.

3.03. Inability to Determine Rates. If the Required Lenders determine that for any reason adequate and reasonable means do not exist for determining the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan, or that the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan does not adequately and fairly reflect the cost to such Lenders of funding such Loan, or that Dollar deposits are not being offered to banks in the London interbank eurodollar market for the applicable amount and the Interest Period of such Eurodollar Rate Loan, the Payment Agent will promptly so notify the Borrower and each Lender. Thereafter, the obligation of the Lenders to make or maintain Eurodollar Rate Loans shall be suspended until the Payment Agent (upon the instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, the Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of Eurodollar Rate Loans or, failing that, will be deemed to have converted such request into a request for Base Rate Loans in the amount specified therein.

3.04. Increased Cost and Reduced Return; Capital Adequacy; Reserves on Eurodollar Rate Loans.

(a) If any Lender determines that as a result of the introduction of or any change in or in the interpretation of any Law, in each case after the date hereof, or such Lender’s compliance therewith, there shall be any increase in the cost to such Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Loans or (as the case may be) issuing or participating in Letters of Credit, or a reduction in the amount received or receivable by such Lender in connection with any of the foregoing (excluding for purposes of this Section 3.04(a) any such increased costs or reduction in amount resulting from (i) Taxes or Other Taxes (as to which Section 3.01 shall govern) and (ii) changes in the basis of taxation of overall net income or overall gross income by the United States or any foreign jurisdiction or any political subdivision of either thereof under the Laws of which such Lender is organized or has its Lending Office), then from time to time upon demand of such Lender (with a copy of such demand to the Payment Agent), the Borrower shall pay to such Lender such additional amounts as will compensate such Lender for such increased cost or reduction.

(b) If any Lender determines that the introduction of any Law regarding capital adequacy or any change therein or in the interpretation thereof, in each case after the date hereof, or compliance by such Lender (or its Lending Office) therewith, has the effect of reducing the rate of return on the capital of such Lender or any corporation controlling such Lender as a consequence of such Lender’s obligations hereunder (taking into consideration its policies with respect to capital adequacy and such Lender’s desired return on capital), then from time to time upon demand of such Lender (with a copy of such demand to the Payment Agent), the Borrower shall pay to such Lender such additional amounts as will compensate such Lender for such reduction.

3.05. Funding Losses. Upon demand of any Lender (with a copy to the Payment Agent) from time to time, the Borrower shall promptly compensate such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of:

(a) any continuation, conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise); or

(b) any failure by the Borrower (for a reason other than the failure of such Lender to make a Loan) to prepay, borrow, continue or convert any Loan other than a Base Rate Loan on the date or in the amount notified by the Borrower;

including any loss of anticipated profits and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained. The Borrower shall also pay any customary administrative fees charged by such Lender in connection with the foregoing.

For purposes of calculating amounts payable by the Borrower to the Lenders under this Section 3.05, each Lender shall be deemed to have funded each Eurodollar Rate Loan made by it at the Eurodollar Rate for such Loan by a matching deposit or other borrowing in the London interbank eurodollar market for a comparable amount and for a comparable period, whether or not such Eurodollar Rate Loan was in fact so funded.

3.06. Matters Applicable to all Requests for Compensation. A certificate of any Agent or any Lender claiming compensation under this Article III and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, such Agent or such Lender may use any reasonable averaging and attribution methods.

3.07. Survival. All of the Borrower’s obligations under this Article III shall survive termination of the Commitments and repayment of all other Obligations hereunder.

ARTICLE IV

(v) within 60 days after such occurrence (if, in the reasonable determination of the Administrative Agents, any such assets have a value in excess of $50,000,000 or any such Restricted Subsidiary being designated a Loan Party under clause (a) above has a net worth in excess of $50,000,000, and if requested by the Administrative Agents), deliver to the Administrative Agents a signed copy of a favorable opinion, addressed to the Administrative Agents and the Collateral Agent and the other Secured Parties, of counsel for the Loan Parties reasonably acceptable to the Administrative Agents as to (i) the matters contained in clauses (a), (c), and (d) above, (ii) such Guaranty, Guaranty Supplement, or applicable Collateral Document being valid and binding obligations of each Loan Party thereto enforceable in accordance with their terms, (iii) such recordings, filings, notices, endorsements, and other actions being sufficient to create valid perfected Liens on such properties, and (iv) such other matters as the Administrative Agents may reasonably request; and

Any right of way purchased, leased, or otherwise acquired or granted after the Closing Date shall be promptly evidenced by an instrument duly executed and recorded against the property it burdens in the appropriate recording office unless the decision to permit such right of way to remain unrecorded is commercially reasonable for companies of the same or similar size in the same or similar business.

(ii) With respect to (x) Real Property owned by Rocky Road Power LLC and (y) Real Property owned or leased by CoGen Lyondell, Inc., in each case, as of the Closing Date (without regard to the Fair Market Value of such Real Property), comply with the requirements of Section 6.13(a)(i) within the time period specified therein (measured from the Closing Date).

(ii) the Borrower shall deliver a local counsel opinion in form and substance reasonably satisfactory to the Administrative Agents;

(iii) the Borrower shall have caused a title company reasonably acceptable to the Administrative Agents to have delivered to the Administrative Agents and the Collateral Trustees a title insurance policy (or, as applicable, an endorsement to the title insurance policy (if any) delivered pursuant to Section 4.01(a)(iv)), date down(s) or other evidence reasonably satisfactory to the Administrative Agents and/or the Collateral Trustees (x) insuring that the priority of the liens evidenced by, or the continuing priority of the Lien of the Mortgage as security for, such Indebtedness, as the case may be, has not changed and (y) confirming and/or insuring that

(A) since the immediately prior incurrence of such Indebtedness, or additional Indebtedness, as the case may be, there has been no change in the condition of title and (B) there are no intervening liens or encumbrances which may then or thereafter take priority over the Lien of the Mortgage, other than the Permitted Liens (without adding any additional exclusions or exceptions to coverage) (a “Modification Endorsement”); and

(iv) the Borrower shall, upon the request of the Administrative Agents and/or the Collateral Trustees, deliver to the approved title company, the Collateral Trustees, the Administrative Agents and/or all other relevant third parties all other items reasonably necessary to maintain the continuing priority of the Lien of the Mortgage as security for such Indebtedness.

6.14. Compliance with Environmental Laws. Except as set forth in any Public Disclosure or except where failure to do so could not, individually or in the aggregate, be reasonably expected to have a Material Adverse Effect, (a) comply, and use commercially reasonable efforts to cause all lessees and other Persons operating or occupying its properties to comply, in all material respects, with all applicable Environmental Laws and Environmental Permits, (b) obtain and renew all Environmental Permits necessary for its operations and properties, and (c) conduct any investigation, study, sampling and testing, required under Environmental Laws and undertake any cleanup, removal, remedial or other action required under Environmental Laws to remove and clean up all Hazardous Materials from any of its properties; provided that neither the Parent Guarantor nor any of its Subsidiaries shall be required to undertake any such cleanup, removal, remedial or other action to the extent that its obligation to do so is being contested in good faith and by proper proceedings with diligence in bringing the matter to closure, appropriate reserves are being maintained with respect to such circumstances, and any such Hazardous Material do not and could not reasonably be expected to pose an imminent and substantial endangerment to human health or the environment.

6.15. Preparation of Environmental Reports. To the extent the Borrower or any Loan Party has the authority to conduct such assessments without obtaining required consent from any other Person, at the request of the Administrative Agents, provide to the Lenders within 90 days after such request, at the expense of the Borrower, an environmental site assessment, soil or groundwater report for any of the properties subject to a Mortgage in the event that (a) any Loan Parties or any of their Subsidiaries receive notice of any Environmental Action relating to any such properties, or any such properties become subject to any Environmental Liability, that individually or in the aggregate could reasonably be expected to result in the Borrower or any of its Restricted Subsidiaries having or becoming subject to liability or liabilities exceeding $50,000,000 or (b) if a Default has occurred and is continuing. With respect to any such properties that require consent from any other person prior to conducting such assessment, the Borrower shall use reasonable efforts to obtain such consent and, if such consent is obtained, will conduct the environmental assessment. If such consent is not granted, the Borrower shall not be required to conduct such assessment. Any environmental site assessment report prepared pursuant to this Section 6.15 shall be prepared by an environmental consulting firm acceptable to the Administrative Agent and shall indicate the presence or absence of Hazardous Materials affecting any subject property and the estimated cost of any compliance, removal or remedial action required under Environmental Laws. Without limiting the generality of the foregoing, if the Administrative Agents determine at any time that a material risk exists that any such report will not be provided within the time referred to above, the Administrative Agents may retain an environmental consulting firm to prepare such report at the expense of the Borrower, and, to the extent the Borrower has the right to grant such authorization or to cause such Subsidiary to grant such authorization, the Borrower hereby grants and agrees to cause any such Subsidiary that owns any property described in such request to grant at the time of such request to the Administrative Agents, the Lenders, such firm and any agents or representatives thereof an irrevocable non-exclusive license, subject to the rights of tenants, to enter onto their respective properties to undertake such an assessment.

Notwithstanding any provision to the contrary contained elsewhere herein or in any other Loan Document, no Agent shall have any duties or responsibilities, except those expressly set forth herein, nor shall any Agent have or be deemed to have any fiduciary relationship with any Lender or participant, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against any Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” herein and in the other Loan Documents with reference to any Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable Law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

(b) Each L/C Issuer shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith, and such L/C Issuer shall have all of the benefits and immunities (i) provided to the Agents in this Article IX with respect to any acts taken or omissions suffered by such L/C Issuer in connection with Letters of Credit issued by it or proposed to be issued by it and the applications and agreements for letters of credit pertaining to such Letters of Credit as fully as if the term “Agent” as used in this Article IX and in the definition of “Agent-Related Person” included such L/C Issuer with respect to such acts or omissions, and (ii) as additionally provided herein with respect to such L/C Issuer.

114

(c) Each of the Lenders (in its capacities as a Lender and L/C Issuer (if applicable)) hereby irrevocably appoints and authorizes the Collateral Agent to act as the agent and as the representative of such Lender for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Loan Parties to secure any of the Secured Obligations, together with such powers and discretion as are reasonably incidental thereto. In this connection, the Collateral Agent (and any co-agents, subagents and attorneys-in-fact appointed by the Collateral Agent or by either Administrative Agent pursuant to Section 9.02 for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Collateral Documents, or for exercising any rights and remedies thereunder at the direction of the Collateral Agent), shall be entitled to the benefits of all provisions of this Article IX (including, without limitation, Section 9.07, as though such co-agents, sub-agents and attorneys-in-fact were the “collateral agent” under the Loan Documents) as if set forth in full herein with respect thereto.

(d) Each of the Lenders hereby irrevocably authorizes the Agents to enter into intercreditor arrangements on behalf of such Lender in respect of the 2003 Second Lien Notes and any other Parity Lien Debt (including amendments thereto, if any, (i) consistent with the terms of this Agreement and (ii) which do not otherwise adversely affect the rights and remedies of the Lenders) and any Permitted Refinancing Indebtedness in respect of the 2003 Second Lien Notes and such Parity Lien Debt.

(e) Each Lender hereby irrevocably authorizes the Collateral Agent to (i) direct the Collateral Trustees to execute the Mortgage Supplements, (ii) consent to the amendment to the Collateral Trust Agreement delivered pursuant to Section 4.01(a)(iv) and (iii) enter into any other documents necessary to reflect the terms of this Agreement or effectuate the provisions in clauses (i) and (ii), in each case, in accordance with the Collateral Trust Agreement.

9.02. Delegation of Duties. Any Agent may execute any of its duties under this Agreement or any other Loan Document (including for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Collateral Documents or of exercising any rights and remedies thereunder at the direction of the Administrative Agents) by or through agents, employees or attorneys-in-fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such duties. No Agent shall be responsible for the negligence or misconduct of any agent or attorney-in-fact that it selects in the absence of gross negligence or willful misconduct.

9.03. Liability of Agents. No Agent-Related Person shall (a) be liable for any action taken or omitted to be taken by any of them under or in connection with this Agreement or any other Loan Document or the transactions contemplated hereby (except for its own gross negligence or willful misconduct in connection with its duties expressly set forth herein), or (b) be responsible in any manner to any Lender or participant for any recital, statement, representation or warranty made by any Loan Party or any officer thereof, contained herein or in any other Loan Document, or in any certificate, report, statement or other document referred to or provided for in, or received by any Agent under or in connection with, this Agreement or any other Loan Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document, or the perfection or priority of any Lien or security interest created or purported to be created under the Collateral Documents, or for any failure of any Loan Party or any other party to any Loan Document to perform its obligations hereunder or thereunder. No Agent-Related Person shall be under any obligation to any Lender or participant to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of any Loan Party or any Affiliate thereof.

115

9.04. Reliance by Agents.

(a) Each Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone message, electronic mail message, statement or other document or conversation 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 (including counsel to any Loan Party), independent accountants and other experts selected by such Agent. Each Agent shall be fully justified in failing or refusing to take any action under any Loan Document unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its 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. Each Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Loan Document in accordance with a request or consent of the Required Lenders (or such greater number of Lenders as may be expressly required hereby in any instance) and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders. The Lenders hereby acknowledge that each 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. Each 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.

(b) For purposes of determining compliance with the conditions specified in Section 4.01, each Lender that has signed this Agreement shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agents shall have received notice from such Lender prior to the proposed Closing Date specifying its objection thereto.

9.05. Notice of Default. No Agent shall be deemed to have knowledge or notice of the occurrence of any Default, except with respect to defaults in the payment of principal, interest and fees required to be paid to the Payment Agent for the account of the Lenders, unless such Agent shall have received written notice from a Lender or the Borrower referring to this Agreement, describing such Default and stating that such notice is a “notice of default.” The Administrative Agents will notify the Lenders of its receipt of any such notice. The Administrative Agents shall take such action, or direct the Collateral Agent to take such action or refrain from taking such action, with respect to such Default as may be directed by the Required Lenders in accordance with Article VIII; provided that unless and until the Administrative Agents or the Collateral Agent, as the case may be, have received any such direction, the Administrative Agents or the Collateral Agent, as the case may be, may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as they shall deem advisable or in the best interest of the Lenders.

9.06. Credit Decision; Disclosure of Information by Agents. Each Lender acknowledges that no Agent-Related Person has made any representation or warranty to it, and that no act by any Agent hereafter taken, including any consent to and acceptance of any assignment or review of the affairs of any Loan Party or any Affiliate thereof, shall be deemed to constitute any representation or warranty by any Agent-Related Person to any Lender as to any matter, including whether Agent-Related Persons have disclosed material information in their possession. Each Lender represents to each Agent that it has, independently and without reliance upon any Agent-Related Person and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial and other condition and creditworthiness of the

116

Loan Parties and their respective Subsidiaries, and all applicable bank or other regulatory Laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to the Borrower and the other Loan Parties hereunder. Each Lender also represents that it will, independently and without reliance upon any Agent-Related Person and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrower and the other Loan Parties. Except for notices, reports and other documents expressly required to be furnished to the Lenders by any Agent herein, such Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any of the Loan Parties or any of their respective Affiliates which may come into the possession of any Agent-Related Person.

9.07. Indemnification of Agents. Whether or not the transactions contemplated hereby are consummated, the Lenders shall indemnify upon demand each Agent-Related Person (to the extent not reimbursed by or on behalf of any Loan Party and without limiting the obligation of any Loan Party to do so), pro rata, and hold harmless each Agent-Related Person from and against any and all Indemnified Liabilities incurred by it; provided that no Lender shall be liable for the payment to any Agent-Related Person of any portion of such Indemnified Liabilities to the extent determined in a final, nonappealable judgment by a court of competent jurisdiction to have resulted from such Agent-Related Person’s own gross negligence or willful misconduct; provided that no action taken by any Agent-Related Person in accordance with the directions of the Required Lenders, and no action taken or refrained from being taken by the Collateral Agent at the direction of an Administrative Agent, shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section 9.07. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Liabilities, this Section 9.07 applies whether any such investigation, litigation or proceeding is brought by any Lender or any other Person. As used herein, “Indemnified Liabilities” for each Agent-Related Person means (i) any amounts not reimbursed by the Borrower for which such Agent-Related Person is entitled to reimbursement by the Borrower under the Loan Documents, (ii) any other reasonable expenses incurred by such Agent-Related Person on behalf of the Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents (including, without limitation, for any reasonable expenses incurred by such Agent-Related Person in connection with any dispute between such Agent-Related Person and any Lender or between two or more of the Lenders) and (iii) any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, reasonable costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against such Agent-Related Person 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 such Agent-Related Person in connection with any dispute between such Agent-Related Person 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. Without limitation of the foregoing, each Lender shall reimburse each Agent and each L/C Issuer upon demand for its ratable share of any reasonable costs or out-of-pocket expenses (including Attorney Costs) incurred by such Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any document contemplated by or referred to herein, to the extent that such Agent is not reimbursed for such expenses by or on behalf of the Borrower. The undertaking in this Section 9.07 shall survive termination of the Commitments, the payment of all other Obligations and the resignation of such Agent.

117

9.08. Agents in their Individual Capacities. Citicorp USA, Inc. and JPMCB and their respective Affiliates may make loans to, issue letters of credit for the account of, accept deposits from, acquire Equity Interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with each of the Loan Parties and their respective Affiliates as though Citicorp USA, Inc. and JPMCB were not Agents hereunder and without notice to or consent of the Lenders. The Lenders acknowledge that, pursuant to such activities, Citicorp USA, Inc. and JPMCB or their respective Affiliates may receive information regarding any Loan Party or its Affiliates (including information that may be subject to confidentiality obligations in favor of such Loan Party or such Affiliate) and acknowledge that no Agent shall be under any obligation to provide such information to them. With respect to its Loans, each of Citicorp USA, Inc. and JPMCB shall have the same rights and powers under this Agreement as any other Lender and may exercise such rights and powers as though it were not an Agent, and the terms “Lender” and “Lenders” include each of Citicorp USA, Inc. and JPMCB in its individual capacity.

9.09. Successor Agents. Any Agent may resign as Agent upon 30 days’ notice to the Borrower and to the Lenders. If any Agent resigns under this Agreement, the Required Lenders shall, with the consent of the Borrower at all times other than during the existence of an Event of Default (which consent of the Borrower shall not be unreasonably withheld or delayed), appoint from among the Lenders a successor agent for the Lenders. If no successor agent is appointed prior to the effective date of the resignation of such Agent, such Agent may appoint, after consulting with the Lenders and the Borrower, a successor agent from among the Lenders. Upon the acceptance of its appointment as successor agent hereunder, the Person acting as such successor agent shall succeed to all the rights, powers and duties of the retiring Agent and the terms “Administrative Agent” and “Collateral Agent” shall mean such successor administrative agent and collateral agent and the retiring Agent’s appointment, powers and duties as Agent shall be terminated. After any retiring Agent’s resignation hereunder as Agent, the provisions of this Article IX and Sections 11.04 and 11.05 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was an Agent under this Agreement. If no successor agent has accepted appointment as Agent by the date which is 30 days following a retiring Agent’s notice of resignation, the retiring Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of such Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above. Upon the acceptance of any appointment as Agent hereunder by a successor and upon the execution and filing or recording of such financing statements, or amendments thereto, and such amendments or supplements to the Mortgages, and such other instruments or notices, as may be necessary or desirable, or as the Required Lenders may request, in order to continue the perfection of the Liens granted or purported to be granted by the Collateral Documents, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, discretion, privileges, and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under the Loan Documents. After any retiring Agent’s resignation hereunder as an Agent, the provisions of this Article IX shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as an Agent.

9.10. Administrative Agents May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to any Loan Party, the Administrative Agents (irrespective of whether the principal of any Loan or L/C Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agents shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, L/C Obligations and all other Obligations that are owing and unpaid and

118

to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Agents (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Agents and their respective agents and counsel and all other amounts due the Lenders and the Agents under Sections 2.03(i) and (j), 2.08 and 11.04) allowed in such judicial proceeding; and

(b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agents and, in the event that the Administrative Agents shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agents any amount due for the reasonable compensation, expenses, disbursements and advances of the Agents and their respective agents and counsel, and any other amounts due the Agents under Sections 2.08 and 11.04.

Nothing contained herein shall be deemed to authorize the Administrative Agents to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or to authorize the Administrative Agents to vote in respect of the claim of any Lender in any such proceeding.

9.11. Collateral and Guaranty Matters.

(a) Provided that no Event of Default then exists, the Collateral Agent shall, and shall direct the Collateral Trustees to, release any Lien on any property granted to or held by the Collateral Agent or the Collateral Trustees under any Loan Document (i) upon termination of the Commitments and payment in full of all Obligations (other than contingent indemnification obligations not yet accrued and payable) and the expiration or termination of all Letters of Credit, (ii) that is Disposed of as part of or in connection with any sale, lease, conveyance or other disposition permitted hereunder or under any other Loan Document, or (iii) subject to Section 11.01(f) and (g), if approved, authorized or ratified in writing by the Required Lenders.

(b) Provided that no Event of Default then exists, the Administrative Agents and the Collateral Agent shall, and shall direct the Collateral Trustees to, release any Loan Party from its obligations under the Loan Documents to which it is a party or by which it is bound (i) if such Person ceases to be a Subsidiary or is no longer required to be a party to the Guaranty as a result of a transaction permitted hereunder or otherwise in accordance with the terms of the Loan Documents, or (ii) subject to Section 11.01(f) and (g), if approved, authorized or ratified in writing by the Required Lenders.

(c) The Collateral Agent and the Administrative Agents, as the case may be, will, at the Borrower’s expense, timely execute and deliver such documents and notices and take such other actions as the Borrower may reasonably request to evidence the release of any Collateral or Loan Documents in accordance with this Section 9.11 and any other applicable terms of the Loan Documents.

(d) Each Lender hereby authorizes the Collateral Agent or the Administrative Agents to take the actions required under this Section 9.11. Without limiting such authorization, the requisite Lenders will timely confirm in writing the authority of the Collateral Agent or the Administrative Agents, as applicable, with respect to any action under this Section 9.11.

9.12. Other Agents; Arrangers and Bookrunners. None of the Lenders or other Persons identified on the facing page or signature pages of this Agreement as a “syndication agent,”

119

“documentation agent,” “co-agent,” “bookrunner,” “lead manager,” “arranger,” “lead arranger” or “co-arranger” shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than, in the case of such Lenders, those applicable to all Lenders as such. Without limiting the foregoing, none of the Lenders or other Persons so identified shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any of the Lenders or other Persons so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

9.13. Appointment of Supplemental Collateral Agents.

(a) It is the purpose of this Agreement and the other Loan Documents that there shall be no violation of any law of any jurisdiction denying or restricting the right of banking corporations or associations to transact business as agent or trustee in such jurisdiction. It is recognized that in case of litigation under this Agreement or any of the other Loan Documents, and in particular in case of the enforcement of any of the Loan Documents, or in case the Administrative Agents deem that by reason of any present or future law of any jurisdiction it may not exercise any of the rights, powers or remedies granted herein or in any of the other Loan Documents or take any other action which may be desirable or necessary in connection therewith, it may be necessary that the Administrative Agents appoint an additional individual or institution as a separate trustee, co-trustee, collateral agent, collateral sub-agent or collateral co-agent (any such additional individual or institution being referred to herein individually as a “Supplemental Collateral Agent” and collectively as “Supplemental Collateral Agents”).

(b) In the event that the Administrative Agents appoint a Supplemental Collateral Agent with respect to any Collateral, (i) each and every right, power, privilege or duty expressed or intended by this Agreement or any of the other Loan Documents to be exercised by or vested in or conveyed to the Administrative Agents with respect to such Collateral shall be exercisable by and vest in such Supplemental Collateral Agent to the extent, and only to the extent, necessary to enable such Supplemental Collateral Agent to exercise such rights, powers and privileges with respect to such Collateral and to perform such duties with respect to such Collateral, and every covenant and obligation contained in the Loan Documents and necessary to the exercise or performance thereof by such Supplemental Collateral Agent shall run to and be enforceable by either the Administrative Agents or such Supplemental Collateral Agents, and (ii) the provisions of this Article and of Section 11.04 that refer to the Administrative Agent shall inure to the benefit of such Supplemental Collateral Agent and all references therein to the Administrative Agent shall be deemed to be references to the Administrative Agents and/or such Supplemental Collateral Agent, as the context may require.

In case any Supplemental Collateral Agent, or a successor thereto, shall die, become incapable of acting, resign or be removed, all the rights, powers, privileges and duties of such Supplemental Collateral Agent, to the extent permitted by law, shall vest in and be exercised by the Administrative Agents until the appointment of a new Supplemental Collateral Agent.

(e) any change, restructuring or termination of the corporate structure or existence of any Loan Party or any of its Subsidiaries;

(f) any failure of any Secured Party to disclose to any Loan Party any information relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of any other Loan Party now or hereafter known to such Secured Party (each Guarantor waiving any duty on the part of the Secured Parties to disclose such information);

(g) the failure of any other Person to execute or deliver this Guaranty, any Guaranty Supplement or any other guaranty or agreement or the release or reduction of liability of any Guarantor or other guarantor or surety with respect to the Guaranteed Obligations; or

(h) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by any Secured Party that might otherwise constitute a defense available to, or a discharge of, any Loan Party or any other guarantor or surety.

This Guaranty shall survive termination of this Agreement and shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be returned by any Secured Party or any other Person upon the insolvency, bankruptcy or reorganization of the Borrower or any other Loan Party or otherwise, all as though such payment had not been made.

(d) Each Guarantor acknowledges that the Collateral Agent may, without notice to or demand upon such Guarantor and without affecting the liability of such Guarantor under this Guaranty, foreclose under any mortgage by nonjudicial sale, and each Guarantor hereby waives any defense to the recovery by the Collateral Agent and the other Secured Parties against such Guarantor of any deficiency after such nonjudicial sale and any defense or benefits that may be afforded by applicable law.

(f) Each Guarantor acknowledges that it will receive substantial direct and indirect benefits from the financing arrangements contemplated by the Loan Documents and that the waivers set forth in Section 10.02 and this Section 10.03 are knowingly made in contemplation of such benefits.

10.04. Subrogation. Each Guarantor hereby unconditionally and irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against the Borrower, any other Loan Party or any other insider guarantor that arise from the existence, payment, performance or enforcement of such Guarantor’s Obligations under or in respect of this Guaranty or any other Loan Document, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of any Secured Party against the Borrower, any other Loan Party or any other insider guarantor or any Collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Borrower, any other Loan Party or any other insider guarantor, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, unless and until all of the Guaranteed Obligations and all other amounts payable under this Guaranty shall have been paid in full in cash, all Letters of Credit shall have expired or been terminated and the Commitments shall have expired or been terminated.

10.05. Guaranty Supplements. Upon the execution and delivery by any Additional Subsidiary Guarantor of a guaranty supplement substantially in the form of Exhibit H (each, a “Guaranty Supplement”), (a) such Person shall become and be a Guarantor hereunder, and each reference in this Guaranty to a “Guarantor” shall also mean and be a reference to such Additional Subsidiary Guarantor, and each reference in any other Loan Document to a “Subsidiary Guarantor” shall also mean and be a reference to such Additional Subsidiary Guarantor, and (b) each reference herein to “this Guaranty,” “hereunder,” “hereof” or words of like import referring to this Guaranty, and each reference in any other Loan Document to the “Guaranty,” “thereunder,” “thereof” or words of like import referring to this Guaranty, shall mean and be a reference to this Guaranty as supplemented by such Guaranty Supplement.

(a) Prohibited Payments, Etc. Except during the continuance of a Default (including the commencement and continuation of any proceeding under any Debtor Relief Law relating to any other Loan Party), each Guarantor may receive regularly scheduled payments from any other Loan Party on account of the Subordinated Obligations. After the occurrence and during the continuance of any Default (including the commencement and continuation of any proceeding under any Debtor Relief Law relating to any other Loan Party), however, unless the Required Lenders otherwise agree, no Guarantor shall demand, accept or take any action to collect any payment on account of the Subordinated Obligations.

(b) Prior Payment of Guaranteed Obligations. In any proceeding under any Debtor Relief Law relating to any other Loan Party, each Guarantor agrees that the Secured Parties shall be entitled to receive payment in full in cash of all Guaranteed Obligations (including all interest and expenses accruing after the commencement of a proceeding under any Debtor Relief Law, whether or not constituting an allowed claim in such proceeding (“Post-Petition Interest”)) before such Guarantor receives payment of any Subordinated Obligations.

(c) Turn-Over. After the occurrence and during the continuance of any Default (including the commencement and continuation of any proceeding under any Debtor Relief Law relating to any other Loan Party), each Guarantor shall, if the Administrative Agents so request, collect, enforce and receive payments on account of the Subordinated Obligations as trustee for the Secured Parties and deliver such payments to the Administrative Agents on account of the Guaranteed Obligations (including all Post-Petition Interest), together with any necessary endorsements or other instruments of transfer, but without reducing or affecting in any manner the liability of such Guarantor under the other provisions of this Guaranty.

(d) Administrative Agents Authorization. After the occurrence and during the continuance of any Default (including the commencement and continuation of any proceeding under any Debtor Relief Law relating to any other Loan Party), the Administrative Agents are authorized and empowered (but without any obligation to so do), in its discretion, (i) in the name of each Guarantor, to collect and enforce, and to submit claims in respect of, Subordinated Obligations and to apply any amounts received thereon to the Guaranteed Obligations (including any and all Post-Petition Interest), and (ii) to require each Guarantor (A) to collect and enforce, and to submit claims in respect of, Subordinated Obligations and (B) to pay any amounts received on such obligations to the Administrative Agents for application to the Guaranteed Obligations (including any and all Post-Petition Interest).

124

10.07. Continuing Guaranty; Assignments. This Guaranty is a continuing guaranty and shall (a) remain in full force and effect until the latest of (i) the payment in full in cash of the Guaranteed Obligations and all other amounts payable under this Guaranty, (ii) the latest maturity date in respect of the Facilities outstanding from time to time and (iii) the latest date of expiration or termination of all Letters of Credit, (b) be binding upon each Guarantor and its successors and assigns and (c) inure to the benefit of and be enforceable by the Secured Parties and their successors, transferees and assigns. Upon the occurrence of the latest date specified in clause (a) above, the Guarantors shall be released from other Obligations under the Loan Documents. Without limiting the generality of clause (c) of the immediately preceding sentence, any Secured Party may assign or otherwise transfer all or any portion of its rights and obligations under this Agreement (including, without limitation, all or any portion of its Commitments, the Advances owing to it and the Note or Notes held by it) to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to such Secured Party herein or otherwise, in each case as and to the extent provided in this Section 10.07. No Guarantor shall have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lenders.

The Agents and the Lenders shall be entitled to rely and act upon any notices (including telephonic Committed Loan Notices) purportedly given by or on behalf of the Borrower even if (i) such notices were not made in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any confirmation thereof. The Borrower shall indemnify each Agent-Related Person and each Lender from all losses, costs, expenses and liabilities resulting from the reliance by such Person on each notice purportedly given by or on behalf of the Borrower. All telephonic notices to and other communications with any Agent may be recorded by such Agent, and each of the parties hereto hereby consents to such recording.

11.03. No Waiver; Cumulative Remedies. No failure by any Lender or any Agent to exercise, and no delay by any such Person in exercising, any right, remedy, power or privilege hereunder or any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided, and provided under each other Loan Document, are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

The foregoing costs and expenses shall include all search, filing, recording, title insurance and appraisal charges and fees and taxes related thereto, and other out-of-pocket expenses incurred by any Agent and the cost of independent public accountants and other outside experts retained by any Agent. All amounts due under this Section 11.04 shall be payable within ten Business Days after demand therefor. The agreements in this Section 11.04 shall survive the termination of the Commitments and repayment of all other Obligations. If any Loan Party fails to pay when due any costs, expenses or other amounts payable by it hereunder or under any Loan Document, including, without limitation, Attorney Costs and indemnities, such amount may be paid on behalf of such Loan Party by any Agent or any Lender, in its sole discretion.

11.05. Release and Indemnification by the Borrower and the Parent Guarantor.

(a) Whether or not the transactions contemplated hereby are consummated, the Borrower and the Parent Guarantor hereby, jointly and severally, unconditionally release and forever discharge each

128

Agent-Related Person, each Lender and their respective Affiliates, successors, assigns, agents, directors, officers, employees, accountants, consultants, contractors, advisors and attorneys (collectively, the “Indemnitees”) from all Claims and jointly and severally agree to indemnify the Indemnitees, and hold them harmless from any and all claims, losses, causes of action, costs and expenses of every kind or character in connection with the Claims. As used in this Agreement, the term “Claims” shall mean any and all possible claims, demands, actions, causes of actions, costs, expenses and liabilities whatsoever, known or unknown, at law or in equity, originating in whole or in part, which the Borrower or the Parent Guarantor, or any of their agents, employees or affiliates may now or hereafter have or claim against any of the Indemnitees and irrespective of whether any such Claims arise out of contract, tort, strict liability, violation of Law or otherwise in connection with any of the Loan Documents and regardless of whether any Indemnitee is a party thereto, in all cases, whether or not caused by or arising, in whole or in part, out of the negligence of the Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses or disbursements are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee. The Borrower and the Parent Guarantor, jointly and severally, agree that none of the Indemnitees have fiduciary or similar obligations to the Borrower or the Parent Guarantor and that their relationships are strictly that of creditor and debtor. This release is accepted by each Lender pursuant to this Agreement and shall not be construed as an admission of liability by any Lender or any other Indemnitee. No Indemnitee shall be liable for any damages arising from the use by others of any information or other materials obtained through IntraLinks or other similar information transmission systems in connection with this Agreement, nor shall any Indemnitee have any liability for any indirect or consequential damages relating to this Agreement or any other Loan Document or arising out of its activities in connection herewith or therewith (whether before or after the Closing Date). In the case of an investigation, litigation or other proceeding to which the indemnity in this Section 11.05 applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by any Loan Party, its directors, shareholders or creditors or an Indemnitee or any other Person, whether or not any Indemnitee is otherwise a party thereto and whether or not any of the transactions contemplated hereunder or under any of the other Loan Documents is consummated. All amounts due under this Section 11.05 shall be payable within ten Business Days after demand therefor. The agreements in this Section 11.05 shall survive the resignation of any Agent, the replacement of any Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all the other Obligations.

(b) THE BORROWER AND EACH GUARANTOR ACKNOWLEDGES THAT THIS AGREEMENT AND OTHER TRANSACTION DOCUMENTS CONTAIN PROVISIONS RELEASING EACH INDEMNITEE FROM LIABILITY AND/OR INDEMNIFYING AND HOLDING HARMLESS EACH INDEMNITEE FOR, AMONG OTHER THINGS, INDEMNITEE’S OWN NEGLIGENCE. EACH OF THE BORROWER AND THE PARENT GUARANTOR AGREES THAT THE RELEASE AND/OR INDEMNITY PROVISIONS CONTAINED IN THESE DOCUMENTS ARE CAPTIONED TO CLEARLY IDENTIFY THE RELEASE AND/OR INDEMNITY PROVISIONS AND, THEREFORE, ARE SO CONSPICUOUS THAT EACH OF THE BORROWER AND THE PARENT GUARANTOR HAS FAIR NOTICE OF THE EXISTENCE AND CONTENTS OF SUCH PROVISIONS. EACH OF THE BORROWER AND THE PARENT GUARANTOR HEREBY WAIVES ANY DEFENSES IT MIGHT ASSERT AGAINST EACH INDEMNITEE BASED ON THE HOLDING OF THE TEXAS SUPREME COURT IN ETHYL CORP. ▇. ▇▇▇▇▇▇ CONST. CO., 725 S.W.2d 705 (Tex. 1987), PAGE PETROLEUM, INC., et al. V. DRESSER INDUSTRIES, INC., et al., 853 S.W.2d 505 (Tex. 1993), AND QUORUM HEALTH RESOURCES, L.L.C. v.

129

11.06. Payments Set Aside. To the extent that any payment by or on behalf of any Loan Party is made to any Agent or any Lender, or any Agent or any Lender exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by such Agent or such Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Law or otherwise, then to the extent permitted by Law (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and (b) each Lender severally agrees to pay to the Administrative Agents upon demand its applicable share of any amount so recovered from or repaid by any Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from time to time in effect.

11.07. Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) in accordance with the provisions of Section 11.07(b), (ii) by way of participation in accordance with the provisions of Section 11.07(d), (iii) by way of pledge or assignment of a security interest subject to the restrictions of Section 11.07(f) or (i), or (iv) to an SPC in accordance with the provisions of Section 11.07(g) (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in Section 11.07(d) and, to the extent expressly contemplated hereby, the Indemnitees) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans (including, for purposes of this Section 11.07(b), participations in Revolving L/C Obligations) at the time owing to it) with the prior consent (not to be unreasonably withheld or delayed) of each of the Borrower, the Payment Agent and (only in the case of assignments of the Revolving Credit Commitments) each Revolving L/C Issuer, provided that (i) no such consent of the Payment Agent shall be required for an assignment of a Term L/C Facility Term Loan to a Lender, an Affiliate of a Lender or an Approved Fund; (ii) no such consent of the Borrower shall be required for an assignment (A) to a Lender, an Affiliate of a Lender or an Approved Fund, (B) if an Event of Default has occurred and is continuing, to any other Person or (C) of a Term L/C Facility Term Loan; (iii) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment under a Facility and the Loans at the time owing to it thereunder or in the case of an assignment to a Lender or an Affiliate of a Lender or by the Administrative Agents, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loan of the assigning Lender subject to each such assignment shall not be less than $5,000,000 (or, in the case of the Term L/C Facility Term Loans, $1,000,000), unless each of the Administrative Agents and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed); (iv) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned under a Facility, except that this clause (iv) shall not prohibit any Lender from assigning all or a portion of its rights and obligations among separate Facilities on a non-pro rata basis; and (v) the parties to each assignment shall execute and deliver to the Payment Agent an Assignment and Assumption, together with a processing and

130

recordation fee of $3,500 (which shall be payable by either the assignor or assignee, as they may agree). Subject to acceptance and recording thereof by the Payment Agent pursuant to Section 11.07(c), from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (other than delinquent obligations to any Revolving L/C Issuer) (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 3.01, 3.04, 3.05, 11.04 and 11.05 with respect to facts and circumstances occurring prior to the effective date of such assignment). Upon request, the Borrower (at its expense) shall execute and deliver a Note to the assignee Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 11.07(b) 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 11.07(d).

(c) The Payment Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at the Payment Agent’s Office a copy of each Assignment and Assumption 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 and the L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Agents 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, any Agent and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agents, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans (including such Lender’s participations in Revolving L/C Obligations) owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Agents and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described in the first proviso to Section 11.01 that directly affects such Participant. Subject to Section 11.07(e), the Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 11.07(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.09 as though it were a Lender, provided such Participant agrees to be subject to Section 2.12 as though it were a Lender.

(e) A Participant shall not be entitled to receive any greater payment under Section 3.01 or 3.04 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.01 unless the Borrower is notified of the participation sold to

131

such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 11.15 as though it were a Lender.

(f) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Note, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(g) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle identified as such in writing from time to time by the Granting Lender to the Payment Agent and the Borrower (an “SPC”) the option to provide all or any part of any Loan that such Granting Lender would otherwise be obligated to make pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to make all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. Each party hereto hereby agrees that (i) neither the grant to any SPC nor the exercise by any SPC of such option shall increase the costs or expenses or otherwise increase or change the obligations of the Borrower under this Agreement (including its obligations under Section 3.04), (ii) no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would be liable, and (iii) the Granting Lender shall for all purposes, including the approval of any amendment, waiver or other modification of any provision of any Loan Document, remain the lender of record hereunder. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior debt of any SPC, it will not institute against, or join any other Person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency, or liquidation proceeding under the laws of the United States or any State thereof. Notwithstanding anything to the contrary contained herein, any SPC may (i) with notice to, but without prior consent of the Borrower and the Payment Agent and with the payment of a processing fee of $3,500, assign all or any portion of its right to receive payment with respect to any Loan to the Granting Lender and (ii) disclose on a confidential basis any non-public information relating to its funding of Loans to any rating agency, commercial paper dealer or provider of any surety or Guarantee or credit or liquidity enhancement to such SPC.

(h) Notwithstanding anything to the contrary contained herein, any Lender may create a security interest in all or any portion of the Loans owing to it and the Note, if any, held by it to the trustee as agent for holders of obligations owed, or securities issued, by such Lender as security for such obligations or securities, provided that unless and until such trustee actually becomes a Lender in compliance with the other provisions of this Section 11.07, (i) no such pledge shall release the pledging Lender from any of its obligations under the Loan Documents and (ii) such trustee shall not be entitled to exercise any of the rights of a Lender under the Loan Documents even though such trustee may have acquired ownership rights with respect to the pledged interest through foreclosure or otherwise.

(i) Notwithstanding anything to the contrary contained herein, if at any time any of Citibank or JPMCB or any other L/C Issuer assigns all of its respective Commitments and Loans pursuant to Section 11.07(b), Citibank, JPMCB or such L/C Issuer, as applicable, may, upon 30 days’ notice to the Borrower and the Lenders, resign as an L/C Issuer. In the event of any such resignation as L/C Issuer, the Borrower shall be entitled to appoint from among the Lenders a successor L/C Issuer hereunder; provided that no failure by the Borrower to appoint any such successor shall affect the resignation of any of Citibank, JPMCB or such L/C Issuer, as applicable, as L/C Issuer. If any of Citibank, JPMCB or any

132

other L/C Issuer, as applicable, resigns as L/C Issuer, it shall retain all the rights and obligations of the L/C Issuers hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as L/C Issuer and all L/C Obligations with respect thereto (including the right to require the Lenders to make Base Rate Loans or fund risk participations in Unreimbursed Amounts pursuant to Section 2.03(c)).

11.08. Confidentiality. Neither any Agent nor any Lender may disclose to any Person any confidential, proprietary or non-public information of the Parent Guarantor and its Subsidiaries furnished to the Agents or the Lenders by any Loan Party (such information being referred to collectively herein as the “Parent Information”), except that each of the Agents and each of the Lenders may disclose Parent Information (i) to its and its affiliates’ employees, officers, directors, agents and other advisors, including accountants and legal counsel (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Parent Information and instructed to keep such Information confidential on substantially the same terms as provided herein), (ii) to the extent requested by any regulatory authority, (iii) to the extent required by applicable laws or regulations or by any judicial order, subpoena or similar legal process or requested by any regulatory body with jurisdiction over any of the Agents or Lenders or their affiliates, employees, officers, directors, agents, accountants, attorneys and other advisors, (iv) to any other party to this Agreement, (v) in connection with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (vi) subject to an agreement containing provisions substantially the same as those of this Section 11.08, to any assignee of or participant in, or any prospective assignee of or participant in, any of its rights or obligations under this Agreement, (vii) to the extent such Parent Information (A) is or becomes generally available to the public on a nonconfidential basis other than as a result of a breach of this Section 11.08 by such Agent or such Lender, or (B) is or becomes available to such Agent or such Lender on a nonconfidential basis from a source other than a Loan Party and (viii) with the consent of the Borrower.

11.09. Setoff. In addition to any rights and remedies of the Lenders provided by law, upon the occurrence and during the continuance of any Event of Default, each Lender and each of their respective Affiliates is authorized at any time and from time to time, with prior notice to the Borrower or any other Loan Party, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held by, and other Indebtedness at any time owing by, such Lender to or for the credit or the account of the respective Loan Parties against any and all Obligations owing to such Lender hereunder or under any other Loan Document, now or hereafter existing, irrespective of whether or not such Agent or such Lender shall have made demand under this Agreement or any other Loan Document and although such Obligations may be contingent or unmatured or denominated in a currency different from that of the applicable deposit or Indebtedness. Each Lender agrees promptly to notify the Borrower, the Payment Agent and the Administrative Agents after any such set-off and application made by such Lender; provided that the failure to give such notice shall not affect the validity of such setoff and application. The rights of the Payment Agent, the Administrative Agents and each Lender and their respective Affiliates under this Section 11.09 are in addition to other rights and remedies (including, without limitation, other rights of setoff) that the Payment Agent, the Administrative Agents, such Lender and their respective Affiliates may have.

11.10. Interest Rate Limitation. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”). If any Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the Borrower. In determining whether the interest contracted for, charged, or received by an Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable Law, (a)

133

characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

11.11. Counterparts. This Agreement and each other Loan Document may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery by telecopier of an executed counterpart of a signature page to this Agreement and each other Loan Document shall be effective as delivery of an original executed counterpart of this Agreement and such other Loan Document. The Agents may also require that any such documents and signatures delivered by telecopier be confirmed by a manually-signed original thereof; provided that the failure to request or deliver the same shall not limit the effectiveness of any document or signature delivered by telecopier.

11.12. Integration. This Agreement, together with the other Loan Documents, comprises the complete and integrated agreement of the parties on the subject matter hereof and thereof and supersedes all prior agreements, written or oral, on such subject matter. In the event of any conflict between the provisions of this Agreement and those of any other Loan Document, the provisions of this Agreement shall control; provided that the inclusion of supplemental rights or remedies in favor of the Agents or the Lenders in any other Loan Document shall not be deemed a conflict with this Agreement. Each Loan Document was drafted with the joint participation of the respective parties thereto and shall be construed neither against nor in favor of any party, but rather in accordance with the fair meaning thereof.

11.13. Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by each Agent and each Lender, regardless of any investigation made by any Agent or any Lender or on their behalf and notwithstanding that any Agent or any Lender may have had notice or knowledge of any Default at the time of any Credit Extension, and shall continue in full force and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

11.14. Severability. If any provision of this Agreement or the other Loan Documents is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Agreement and the other Loan Documents shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

11.15. Tax Forms.

(a) Each Lender that is not a “United States person” within the meaning of Section 7701(a)(30) of the Code (a “Foreign Lender”) shall deliver to the Payment Agent, prior to receipt of any payment subject to withholding under the Code (or upon accepting an assignment of an interest herein), two duly signed completed copies of either IRS Form W-8BEN or any successor thereto (relating to such Foreign Lender and entitling it to an exemption from, or reduction of, withholding tax on all payments to be made to such Foreign Lender by the Borrower pursuant to this Agreement) or IRS Form W-8ECI or any successor thereto (relating to all payments to be made to such Foreign Lender by the Borrower pursuant to this Agreement) or such other evidence satisfactory to the Borrower and the Payment Agent that such Foreign Lender is entitled to an exemption from, or reduction of, U.S. withholding tax,

134

including any exemption pursuant to Section 881(c) of the Code, and in the case of a Foreign Lender claiming such an exemption under Section 881(c) of the Code, a certificate that establishes in writing to the Administrative Agent that such Foreign Lender is not (i) a “bank” as defined in Section 881(c)(3)(A) of the Code, (ii) a 10-percent shareholder within the meaning of Section 871(h)(3)(B) of the Code, and (iii) a controlled foreign corporation related to the Borrower within the meaning of Section 864(d) of the Code. Thereafter and from time to time, each such Foreign Lender shall (A) promptly submit to the Payment Agent such additional duly completed and signed copies of one of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may then be available under then current United States laws and regulations to avoid, or such evidence as is satisfactory to the Borrower and the Payment Agent of any available exemption from or reduction of, United States withholding taxes in respect of all payments to be made to such Foreign Lender by the Borrower pursuant to this Agreement, (B) promptly notify the Payment Agent of any change in circumstances which would modify or render invalid any claimed exemption or reduction, and (C) take such steps as shall not be materially disadvantageous to it, in the reasonable judgment of such Lender, and as may be reasonably necessary (including the re-designation of its Lending Office) to avoid any requirement of applicable Laws that the Borrower make any deduction or withholding for taxes from amounts payable to such Foreign Lender.

(i) Each Foreign Lender, to the extent it does not act or ceases to act for its own account with respect to any portion of any sums paid or payable to such Lender under any of the Loan Documents (for example, in the case of a typical participation by such Lender), shall deliver to the Payment Agent on the date when such Foreign Lender ceases to act for its own account with respect to any portion of any such sums paid or payable, and at such other times as may be necessary in the determination of the Payment Agent (in the reasonable exercise of its discretion), (A) two duly signed completed copies of the forms or statements required to be provided by such Lender as set forth above, to establish the portion of any such sums paid or payable with respect to which such Lender acts for its own account that is not subject to U.S. withholding tax, and (B) two duly signed completed copies of IRS Form W-81MY (or any successor thereto), together with any information such Lender chooses to transmit with such form, and any other certificate or statement of exemption required under the Code, to establish that such Lender is not acting for its own account with respect to a portion of any such sums payable to such Lender.

(ii) The Borrower shall not be required to pay any additional amount to any Foreign Lender under Section 3.01 (A) with respect to any Taxes required to be deducted or withheld on the basis of the information, certificates or statements of exemption such Lender transmits with an IRS Form W-8IMY pursuant to this Section 11.15(a) or (B) if such Lender shall have failed to satisfy the foregoing provisions of this Section 11.15(a); provided that if such Lender shall have satisfied the requirement of this Section 11.15(a) on the date such Lender became a Lender or ceased to act for its own account with respect to any payment under any of the Loan Documents, nothing in this Section 11.15(a) shall relieve the Borrower of its obligation to pay any amounts pursuant to Section 3.01 in the event that, as a result of any change in any applicable Law, treaty or governmental rule, regulation or order, or any change in the interpretation, administration or application thereof, such Lender is no longer properly entitled to deliver forms, certificates or other evidence at a subsequent date establishing the fact that such Lender or other Person for the account of which such Lender receives any sums payable under any of the Loan Documents is not subject to withholding or is subject to withholding at a reduced rate.

135

(iii) The Payment Agent may, without reduction, withhold any Taxes required to be deducted and withheld from any payment under any of the Loan Documents with respect to which the Borrower is not required to pay additional amounts under this Section 11.15(a).

(b) Upon the request of the Payment Agent, each Lender that is a “United States person” within the meaning of Section 7701(a)(30) of the Code shall deliver to the Payment Agent two duly signed completed copies of IRS Form W-9. If such Lender fails to deliver such forms, then the Payment Agent may withhold from any interest payment to such Lender an amount equivalent to the applicable back-up withholding tax imposed by the Code, without reduction.

(c) If any Governmental Authority asserts that the Payment Agent did not properly withhold or backup withhold, as the case may be, any tax or other amount from payments made to or for the account of any Lender, such Lender shall indemnify the Payment Agent therefor, including all penalties and interest, any taxes imposed by any jurisdiction on the amounts payable to the Payment Agent under this Section 11.15, and costs and expenses (including Attorney Costs) of the Payment Agent. The obligation of the Lenders under this Section 11.15 shall survive the termination of the Commitments, repayment of all other Obligations hereunder and the resignation of the Payment Agent.

11.16. Governing Law.

(a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

(b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN ▇▇▇ ▇▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇ SITTING IN NEW YORK CITY OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF SUCH STATE, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE BORROWER, EACH AGENT AND EACH LENDER CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. THE BORROWER, EACH AGENT AND EACH LENDER IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF ANY LOAN DOCUMENT OR OTHER DOCUMENT RELATED THERETO. THE BORROWER, EACH AGENT AND EACH LENDER WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY THE LAW OF SUCH STATE.

11.17. Waiver of Right to Trial by Jury. EACH PARTY TO THIS AGREEMENT HEREBY KNOWINGLY, INTENTIONALLY AND VOLUNTARILY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM WITH RESPECT TO ANY LOAN DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 11.17

136

WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

11.18. Binding Effect. This Agreement shall become effective when it shall have been executed by the Borrower and each Guarantor and each Administrative Agent shall have been notified by each Lender and each L/C Issuer that each such Lender or L/C Issuer, as the case may be, has executed it and thereafter shall be binding upon and inure to the benefit of the Borrower, and each Guarantor, each Agent-Related Person and each Lender and their respective successors and assigns and shall inure to the benefit of each Indemnitee, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lenders.

11.19. Amendment and Restatement. This Agreement is an amendment and restatement (but not an extinguishment) of the Existing DHI Credit Agreement and, other than as specifically amended and restated herein, the rights and obligations of the parties thereto shall remain in full force and effect. Each Revolving Credit Lender that is a “Lender” under the Existing DHI Credit Agreement hereby waives any requirement thereunder to receive prior notice of the prepayment of any loans and/or termination of commitments thereunder, if applicable, and each such Revolving Credit Lender agrees that as of the Closing Date it shall have, and continue to have, a Revolving Credit Commitment hereunder in the amount set forth opposite such Lender’s name on Schedule 2.01.

11.20. USA PATRIOT Act. Each Lender hereby notifies each Loan Party that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), it is required to obtain, verify and record information that identifies each Loan Party, which information includes the name and address of such Loan Party and other information that will allow such Lender to identify such Loan Party in accordance with said Act.

11.21. Lender Addendum. Each initial Lender shall become a party to this Agreement by either signing a counterpart of this Agreement or delivering to the Administrative Agents a Lender Addendum duly executed by such Lender and the Borrower.

137

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed as of the date first above written.
