If (due to the existence of a Default or for any other reason) Borrower fails to timely and properly give any Continuation/Conversion Notice with respect to a Borrowing of existing LIBOR Loans at least three days prior to the end of the Interest Period applicable to such LIBOR Loans, any such LIBOR Loans, to the extent not prepaid at the end of such Interest Period, shall automatically be Converted into Base Rate Loans at the end of such Interest Period. No new funds shall be repaid by Borrower or advanced by any Lender in connection with any Continuation or Conversion of existing Loans pursuant to this section, and no such Continuation or Conversion shall be deemed to be a new advance of funds for any purpose; such Continuations and Conversions merely constitute a change in the interest rate applicable to such already outstanding Loans.

Each Restricted Person shall pay all amounts owing by such Restricted Person with respect to any Obligations (whether for principal, interest, fees, or otherwise) to Administrative Agent for the account of the Lender Party to whom such payment is owed in Dollars, without set-off, deduction or counterclaim, and in immediately available funds. Each payment under the Loan Documents must be received by Administrative Agent not later than noon, New York City time, on the date such payment becomes due and payable. Any payment received by Administrative Agent after such time will be deemed to have been made on the next following Business Day. Should any such payment become due and payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day, and, in the case of a payment of principal or past due interest, interest shall accrue and be payable thereon for the period of such extension as provided in the Loan Document under which such payment is due. Each payment under a Loan Document to a Lender Party shall be due and payable at the place provided therein and, if no specific place of payment is provided, shall be due and payable at the place of payment of Administrative Agent's Note.

(a) When Administrative Agent collects or receives money on account of the Obligations, Administrative Agent shall distribute all money so collected or received, and each Lender Party shall apply all such money so distributed, as follows:

(i) first, for the payment of all Obligations which are then due (and if such money is insufficient to pay all such Obligations, first to any reimbursements due Administrative Agent under Section 10.4 and then to the partial payment of all other Obligations then due in proportion to the amounts thereof, or as Lender Parties shall otherwise agree);

(ii) then for the prepayment of amounts owing under the Loan Documents (other than principal on the Notes) if so specified by Borrower;

(iii) then for the prepayment of principal on the Notes, together with accrued and unpaid interest on the principal so prepaid; and

(iv) last, for the payment or prepayment of any other Obligations.

All payments applied to principal or interest on any Note shall be applied first to any interest then due and payable, then to principal then due and payable, and last to any prepayment of principal and accrued interest thereon in compliance with Sections 2.8 and 2.9, as applicable. All distributions of amounts described in any of subsections (ii), (iii), or (iv) above shall be made by Administrative Agent pro rata to each Lender Party then owed Obligations described in such subsection in proportion to all amounts owed to all Lender Parties which are described in such subsection; provided that if any Lender then owes payments to Administrative Agent under Section 9.4, any amounts otherwise distributable under this section to such Lender shall be deemed to belong to Administrative Agent, to the extent of such unpaid payments, and Administrative Agent shall apply such amounts to make such unpaid payments rather than distribute such amounts to such Lender.

Section 3.2. Capital Reimbursement. If either (a) the introduction or implementation of or the compliance with or any change in or in the interpretation of any Law, or (b) the introduction or implementation of or the compliance with any request, directive or guideline from any central bank or other governmental authority (whether or not having the force of Law) affects or would affect the amount of capital required or expected to be maintained by any Lender Party or any corporation controlling any Lender Party, then, within five Business Days after demand by such Lender Party, Borrower will pay to Administrative Agent for the benefit of such Lender Party, from time to time as specified by such Lender Party, such additional amount or amounts which such Lender Party shall determine to be appropriate to compensate such Lender Party or any corporation controlling such Lender Party in light of such circumstances, to the extent that such Lender Party reasonably determines

that the amount of any such capital would be increased or the rate of return on any such capital would be reduced by or in whole or in part based on the existence of the face amount of such Lender Party's Loans or commitments under this Agreement.

Section 3.3. Increased Cost of LIBOR Loans. If any applicable Law (whether now in effect or hereinafter enacted or promulgated, including Regulation D) or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof (whether or not having the force of Law):

(a) shall change the basis of taxation of payments to any Lender Party of any principal, interest, or other amounts attributable to any LIBOR Loan or otherwise due under this Agreement in respect of any LIBOR Loan (other than taxes imposed on, or measured by, the overall net income of such Lender Party or any Applicable Lending Office of such Lender Party by any jurisdiction in which such Lender Party or any such Applicable Lending Office is located); or

(b) shall change, impose, modify, apply or deem applicable any reserve, special deposit or similar requirements in respect of any LIBOR Loan (excluding those for which such Lender Party is fully compensated pursuant to adjustments made in the definition of LIBOR Rate) or against assets of, deposits with or for the account of, or credit extended by, such Lender Party; or

(c) shall impose on any Lender Party or the interbank Eurocurrency deposit market any other condition affecting any LIBOR Loan, the result of which is to increase the cost to any Lender Party of funding or maintaining any LIBOR Loan or to reduce the amount of any sum receivable by any Lender Party in respect of any LIBOR Loan by an amount deemed by such Lender Party to be material, then such Lender Party shall promptly notify Administrative Agent and Borrower in writing of the happening of such event and of the amount required to compensate such Lender Party for such event (on an after-tax basis, taking into account any taxes on such compensation), whereupon (i) Borrower shall, within five Business Days after demand therefor by such Lender Party, pay such amount to Administrative Agent for the account of such Lender Party and (ii) Borrower may elect, by giving to Administrative Agent and such Lender Party not less than three Business Days' notice, to Convert all (but not less than all) of any such LIBOR Loans into Base Rate Loans.

Section 3.4. Notice; Change of Applicable Lending Office. A Lender Party shall notify Borrower of any event occurring after the date of this Agreement that will entitle such Lender Party to compensation under Section 3.2, 3.3, or 3.5 hereof as promptly as practicable, but in any event within 180 days, after such Lender Party obtains actual knowledge thereof; provided, that (i) if such Lender Party fails to give such notice within 180 days after it obtains actual knowledge of such an event, such Lender Party shall, with respect to compensation payable pursuant to Section 3.2, 3.3, or 3.5 in respect of any costs resulting from such event, only be entitled to payment under Section 3.2, 3.3, or 3.5 hereof for costs incurred from and after the date 180 days prior to the date that such Lender Party does give such notice and (ii) such Lender Party will designate a different Applicable Lending Office for the Loans affected by such event if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender Party, be disadvantageous to such Lender Party, except that such Lender Party shall have no obligation to designate an Applicable Lending Office located in the United States of America. Each Lender Party will furnish to Borrower a certificate setting forth the basis and amount of each request by such Lender Party for compensation under Section 3.2, 3.3, or 3.5 hereof.

Section 3.5. Availability. If (a) any change in applicable Laws, or in the interpretation or administration thereof of or in any jurisdiction whatsoever, domestic or foreign, shall make it unlawful or impracticable for any Lender Party to fund or maintain LIBOR Loans, or shall materially restrict the authority of any Lender Party to purchase or take offshore deposits of dollars (i.e., "Eurodollars"), or (b) any Lender Party determines that matching deposits appropriate to fund or maintain any LIBOR Loan are not available to it, or (c) any Lender Party determines that the formula for calculating the

LIBOR Rate does not fairly reflect the cost to such Lender Party of making or maintaining loans based on such rate, with respect to the Commitment hereunder, then, upon notice by such Lender Party to Borrower and Administrative Agent, Borrower's right to elect LIBOR Loans from such Lender Party shall be suspended to the extent and for the duration of such illegality, impracticability or restriction and all LIBOR Loans of such Lender Party which are then outstanding or are then the subject of any Borrowing Notice and which cannot lawfully or practicably be maintained or funded shall immediately become or remain, or shall be funded as, Base Rate Loans of such Lender Party. With respect to the Commitment, Borrower agrees to indemnify each Lender Party extending credit pursuant thereto, and hold each such Lender Party harmless against all costs, expenses, claims, penalties, liabilities and damages which may result from any such change in Law, interpretation or administration. Such indemnification shall be on an after-tax basis, taking into account any taxes imposed on the amounts paid as indemnity.

Section 3.6. Funding Losses. In addition to its other obligations hereunder, with respect to the Commitment, Borrower will indemnify each Lender Party extending credit pursuant thereto against, and reimburse each Lender Party on demand for, any loss or expense incurred or sustained by such Lender Party (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender Party to fund or maintain LIBOR Loans), as a result of (a) any payment or prepayment (whether or not authorized or required hereunder) of all or a portion of a LIBOR Loan on a day other than the day on which the applicable Interest Period ends, (b) any payment or prepayment, whether or not required hereunder, of a Loan made after the delivery, but before the effective date, of a Continuation/Conversion Notice, if such payment or prepayment prevents such Continuation/Conversion Notice from becoming fully effective, (c) the failure of any Loan to be made or of any Continuation/Conversion Notice to become effective due to any condition precedent not being satisfied or due to any other action or inaction of any Restricted Person, or (d) any Conversion (whether or not authorized or required hereunder) of all or any portion of any LIBOR Loan into a Base Rate Loan or into a different LIBOR Loan on a day other than the day on which the applicable Interest Period ends. Such indemnification shall be on an after-tax basis, taking into account any taxes imposed on the amounts paid as indemnity.

Section 3.7. Reimbursable Taxes. With respect to the Commitment, Borrower covenants and agrees with each Lender Party extending credit pursuant thereto that:

(a) Borrower will indemnify each such Lender Party against and reimburse each such Lender Party for all present and future stamp and other taxes, duties, levies, imposts, deductions, charges, costs, and withholdings whatsoever imposed, assessed, levied or collected on or in respect of this Agreement, any LIBOR Loans (whether or not legally or correctly imposed, assessed, levied or collected), excluding, however, any taxes imposed on or measured by the overall net income of Administrative Agent or such Lender Party or any Applicable Lending Office of such Lender Party by any jurisdiction in which such Lender Party or any such Applicable Lending Office is located (all such non-excluded taxes, levies, costs and charges being collectively called "Reimbursable Taxes" in this section). Such indemnification shall be on an after-tax basis, taking into account any taxes imposed on the amounts paid as indemnity.

(b) All payments on account of the principal of, and interest on, each such Lender Party's Loans and Note, and all other amounts payable by Borrower to any such Lender Party hereunder, shall be made in full without set-off or counterclaim and shall be made free and clear of and without deductions or withholdings of any nature by reason of any Reimbursable Taxes, all of which will be for the account of Borrower. In the event of Borrower being compelled by Law to make any such deduction or withholding from any payment to any such Lender Party, Borrower shall pay on the due date of such payment, by way of additional interest, such additional amounts as are needed to cause the amount receivable by such Lender Party after such deduction or withholding to equal the amount which would have been receivable in the absence of such deduction or withholding. If Borrower should

make any deduction or withholding as aforesaid, Borrower shall within 60 days thereafter forward to such Lender Party an official receipt or other official document evidencing payment of such deduction or withholding.

(c) If Borrower is ever required to pay any Reimbursable Tax with respect to any LIBOR Loan, Borrower may elect, by giving to Administrative Agent and such Lender Party not less than three Business Days' notice, to Convert all (but not less than all) of any such LIBOR Loan into a Base Rate Loan, but such election shall not diminish Borrower's obligation to pay all Reimbursable Taxes.

(d) Notwithstanding the foregoing provisions of this section, Borrower shall be entitled, to the extent it is required to do so by Law, to deduct or withhold (and not to make any indemnification or reimbursement for) income or other similar taxes imposed by the United States of America (other than any portion thereof attributable to a change in federal income tax Laws effected after the date hereof) from interest, fees or other amounts payable hereunder for the account of such Lender Party, other than such a Lender Party (i) who is a US person for Federal income tax purposes or (ii) who has the Prescribed Forms on file with Administrative Agent (with copies provided to the relevant Borrower) for the applicable year to the extent deduction or withholding of such taxes is not required as a result of the filing of such Prescribed Forms, provided that if Borrower shall so deduct or withhold any such taxes, it shall provide a statement to Administrative Agent and such Lender Party, setting forth the amount of such taxes so deducted or withheld, the applicable rate and any other information or documentation which such Lender Party may reasonably request for assisting such Lender Party to obtain any allowable credits or deductions for the taxes so deducted or withheld in the jurisdiction or jurisdictions in which such Lender Party is subject to tax. As used in this section, "Prescribed Forms" means such duly executed forms or statements, and in such number of copies, which may, from time to time, be prescribed by Law and which, pursuant to applicable provisions of (x) an income tax treaty between the United States and the country of residence of such Lender Party providing the forms or statements, (y) the Code, or (z) any applicable rules or regulations thereunder, permit Borrower to make payments hereunder for the account of such Lender Party free of such deduction or withholding of income or similar taxes.

Section 3.8. Replacement of Lenders. If any Lender Party seeks reimbursement for increased costs under Sections 3.2 through 3.7, then within ninety days thereafter—provided no Event of Default then exists—Borrower shall have the right (unless such Lender Party withdraws its request for additional compensation) to replace such Lender Party by requiring such Lender Party to assign its Loans and Note and its commitments hereunder to an Eligible Transferee reasonably acceptable to Administrative Agent and to Borrower, provided that: (i) all Obligations of Borrower owing to such Lender Party being replaced (including such increased costs and any breakage costs with respect to any outstanding LIBOR Loans, but excluding principal and accrued interest on the Note being assigned) shall be paid in full to such Lender Party concurrently with such assignment, and (ii) the replacement Eligible Transferee shall purchase the Notes being assigned by paying to such Lender Party a price equal to the principal amount thereof plus accrued and unpaid interest and accrued and unpaid commitment fees thereon. In connection with any such assignment Borrower, Administrative Agent, such Lender Party and the replacement Eligible Transferee shall otherwise comply with Section 10.5. Notwithstanding the foregoing rights of Borrower under this section, however, Borrower may not replace any Lender Party which seeks reimbursement for increased costs under Section 3.2 through 3.7 unless Borrower is at the same time replacing all Lender Parties which are then seeking such compensation.

Each Significant Restricted Person is duly organized or formed, validly existing and in good standing under the Laws of its jurisdiction of organization or formation, having all requisite corporate or similar powers required to carry on its business and enter into and carry out the transactions contemplated hereby. Each Significant Restricted Person is duly qualified, in good standing, and authorized to do business in all other jurisdictions wherein the character of the properties owned or held by it or the nature of the business transacted by it makes such qualification necessary except where the failure to so qualify would not reasonably be expected to cause a Material Adverse Change.

Section 5.3. Authorization. Each Restricted Person has duly taken all action necessary to authorize the execution and delivery by it of the Loan Documents to which it is a party and to authorize the consummation of the transactions contemplated thereby and the performance of its obligations thereunder. Borrower is duly authorized to borrow funds hereunder.

Section 5.4. No Conflicts or Consents. The execution and delivery by each Restricted Person of the Loan Documents to which it is a party, the performance by it of its obligations, and the consummation of the transactions contemplated thereby, do not and will not (i) violate any provision of (1) Law applicable to it, (2) its organizational documents or (3) any judgment, order or material license or permit applicable to or binding upon it, (ii) result in the acceleration of any Indebtedness owed by it or (iii) result in or require the creation of any consensual Lien upon any of its material assets or properties except as expressly contemplated in, or permitted by, the Loan Documents.

The Initial Financial Statements fairly present Borrower's Consolidated financial position at the date thereof and the Consolidated results of Borrower's operations for the periods thereof, and in the case of the annual Initial Financial Statements, Consolidated cash flows for the period thereof. Since the date of the annual Initial Financial Statements, no Material Adverse Change has occurred.

As of the closing date hereof, no Restricted Person has any outstanding payment obligations of any kind (including contingent obligations, tax assessments and unusual forward or long-term commitments) which are, in the aggregate, material to Borrower or material with respect to Borrower's Consolidated financial condition and not reflected in

the Initial Financial Statements, disclosed in the Disclosure Schedule or otherwise permitted under Section 7.1. Except as reflected disclosed in the Disclosure Schedule, no Restricted Person is subject to or restricted by any franchise, contract, deed, charter restriction, or other instrument or restriction which would reasonably be expected to cause a Material Adverse Change.

Section 5.8. Full Disclosure. No certificate, statement or other information delivered herewith or heretofore by any Restricted Person to any Lender in connection with the negotiation of this Agreement or in connection with any transaction contemplated hereby contains any untrue statement of a material fact or omits to state any material fact necessary to make the statements contained herein or therein, in light of the circumstances under which they were made, not misleading as of the date made or deemed made (or if such information expressly relates or refers to an earlier date, as of such earlier date). All written information furnished after the date hereof by or on behalf of any Restricted Person to Administrative Agent or any Lender Party in connection with this Agreement and the other Loan Documents and the transactions contemplated hereby and thereby will be true, complete and accurate in every material respect in light of the circumstances in which made or based on reasonable estimates, in each case as of the date on which such information is stated or certified (or if such information expressly relates or refers to an earlier date, as of such earlier date).

Except as disclosed in the Initial Financial Statements, in the Disclosure Schedule or pursuant to Section 6.4, no Termination Event has occurred with respect to any ERISA Plan and all ERISA Affiliates are in compliance with ERISA in all material respects, to the extent that the non-compliance therewith would not be reasonably expected to cause a Material Adverse Change.

Except as set forth in the Disclosure Schedule or pursuant to Section 6.4, each Restricted Person has all permits, licenses and authorizations required in connection with the conduct of its businesses, except to the extent failure to have any such permit, license or authorization would not reasonably be expected to cause a Material Adverse Change. Each Restricted Person is in compliance with the terms and conditions of all such permits, licenses and authorizations, and is also in compliance with all other limitations, restrictions, conditions, standards, prohibitions, requirements, obligations, schedules and timetables contained in any Law, including applicable Environmental Law, or in any regulation, code, plan, order, decree, judgment, injunction, notice or demand letter issued, entered, promulgated or approved thereunder, except to the extent that non-compliance therewith would not reasonably be expected to cause a Material Adverse Change or

such term, restriction or otherwise is being contested in good faith or a bona fide dispute exists with respect thereto.

Section 5.12. Environmental Laws. Except as set forth in the Disclosure Schedule or disclosed pursuant to Section 6.4, (i) Borrower and its Subsidiaries are conducting their businesses in material compliance with all applicable Laws, including Environmental Laws, and have and are in compliance with all licenses and permits required under any such Laws, unless failure to so comply or have such licenses and permits would not reasonably be expected to cause a Material Adverse Change; (ii) none of the operations or properties of Borrower or any of its Subsidiaries is the subject of federal, provincial or local investigation evaluating whether any material remedial action is needed to respond to a release of any Hazardous Materials into the environment or to the improper storage or disposal (including storage or disposal at offsite locations) of any Hazardous Materials, unless such remedial action would not reasonably be expected to cause a Material Adverse Change; and (iii) neither Borrower nor any of its Subsidiaries (and to the actual knowledge of Borrower, no other Person) has filed any notice under any Law indicating that any Restricted Person is responsible for the improper release into the environment, or the improper storage or disposal, of any material amount of any Hazardous Materials or that any Hazardous Materials have been improperly released, or are improperly stored or disposed of, upon any property of any such Person, other than of an alleged improper release, storage or disposal that would not reasonably be expected to cause a Material Adverse Change.

Section 5.13. Borrower's Subsidiaries. Borrower has no Subsidiary and owns no stock in any other corporation or association except as listed in the Disclosure Schedule or disclosed after the closing date hereof to Administrative Agent in writing. No Restricted Person is a member of any general or limited partnership, limited liability company, joint venture or association of any type whatsoever except those listed in the Disclosure Schedule or disclosed after the closing date hereof to Administrative Agent in writing. Borrower owns, directly or indirectly, the equity interest in each of its Subsidiaries which is indicated in the Disclosure Schedule.

Section 5.14. Title to Properties. Each Restricted Person has good and defensible title to all of its material properties and assets, free and clear of all Liens (other than Permitted Liens) and of all impediments to the use of such properties and assets in such Restricted Person's business, other than such impediments that would not reasonably be expected to cause a Material Adverse Change.

Section 5.15. Government Regulation. Neither Borrower nor any other Restricted Person owing Obligations is subject to regulation under the Public Utility Holding Company Act of 1935, the Investment Company Act of 1940 (as any of the preceding acts have been amended) or any other Law which regulates the incurring by such Person of Indebtedness, including Laws relating to common contract carriers or the sale of electricity, gas, steam, water or other public utility services. Neither Borrower nor any other Restricted Person is subject to regulation under the Federal Power Act which would violate, result in a default of, or prohibit the effectiveness or the performance of any of the provisions of the Loan Documents.

Section 5.16. Insider. No Restricted Person, nor any Person having "control" (as that term is defined in 12 U.S.C. § 375b(9) or in regulations promulgated pursuant thereto) of any Restricted Person, is a "director" or an "executive officer" or "principal shareholder" (as those terms are defined in 12 U.S.C. § 375b(8) or (9) or in regulations promulgated pursuant thereto) of any Lender, of a bank holding company of which any Lender is a Subsidiary or of any Subsidiary of a bank holding company of which any Lender is a Subsidiary.

Section 5.17. Solvency. Upon giving effect to the issuance of the Notes, the execution of the Loan Documents by Borrower and each Guarantor and the consummation of the transactions contemplated hereby, (i) Borrower and each Guarantor will be solvent (as such term is used in applicable bankruptcy, liquidation, receivership, insolvency or similar Laws), and the sum of Borrower's

and each Guarantor's absolute and contingent liabilities, including the Obligations or guarantees thereof, shall not exceed the fair market value of such Restricted Person's assets, and (ii) Borrower's and each Guarantor's capital should be adequate for the businesses in which such Restricted Person is engaged and intends to be engaged. Neither Borrower nor any other Restricted Person has incurred (whether under the Loan Documents or otherwise), nor does any Restricted Person intend to incur or reasonably foreseeably believes that it will incur, debts which will be beyond its ability to pay as such debts mature.

Section 5.18. Not a "Reportable Transaction". Borrower does not intend to treat the Borrowings and related transactions as being a "reportable transaction" (within the meaning of Treasury Regulation Section 1.6011-4). In the event Borrower determines to take any action inconsistent with such intention, it will promptly notify the Administrative Agent thereof. If Borrower takes any action inconsistent with such intention, or if Borrower so notifies the Administrative Agent, then Borrower acknowledges that, as a result of such action or notice, one or more of the Lenders may treat its Loans as part of a transaction that is subject to Treasury Regulation Section 301.6112-1, and such Lender or Lenders will maintain the lists and other records required by such Treasury Regulation.

ARTICLE VI—Affirmative Covenants

To conform with the terms and conditions under which each Lender is willing to have credit outstanding to Borrower, and to induce each Lender to enter into this Agreement and extend credit hereunder, Borrower covenants and agrees that until the full and final payment of the Obligations and the termination of this Agreement, unless Majority Lenders, or all Lenders as required under Section 10.1, have previously agreed otherwise:

Section 6.1. Payment and Performance.

Section 6.7. Insurance. In accordance with industry standards, each Significant Restricted Person will keep insured (by responsible and reputable insurance companies or associations) or self-insured, at the option of Borrower or such Significant Restricted Person, in such amounts and against such risks as are usually insured by Persons engaged in the same or similar businesses and owning similar properties.

Section 6.9. Guaranties of Subsidiaries. Each Significant Restricted Person that has outstanding Indebtedness (other than guarantees hereunder) shall execute and deliver to Administrative Agent an absolute and unconditional guaranty of the timely repayment of the Obligations (in each case for which such Person is not a borrower, account party or similar primary and direct obligor), which guaranty shall be reasonably satisfactory to Administrative Agent in form and substance; provided, with respect to any such Person that is not a Wholly Owned Subsidiary of Borrower, for which consent or approval of third parties is required for the delivery of such guaranty, such Person shall not be required to deliver such guaranty, but shall use its commercially reasonable best efforts, as determined by Administrative Agent, to deliver such guaranty. Notwithstanding any provision contained herein, in no event shall any Unrestricted Subsidiary be required to execute and deliver any guaranty for, or in respect of, the Obligations, or any part thereof. Borrower will cause each of its Subsidiaries required to deliver a guaranty pursuant to this Section 6.9 to deliver to Administrative Agent, simultaneously with its delivery of such a guaranty, written evidence satisfactory to Administrative Agent that such Subsidiary has taken all corporate, limited liability company or partnership action necessary to duly approve and authorize its execution, delivery and performance of such guaranty. Borrower may at any time request the release of one or more Guarantors from their guaranty of the Obligations, and each such Guarantor shall be so released upon such request, provided, no Default then exists and either (a) such Guarantor has no outstanding Indebtedness or guaranties of Indebtedness (other than guaranties hereunder) or (b) the request is in contemplation of the sale or disposition of such Subsidiary (including all or substantially all of its assets). Administrative Agent is authorized to execute and deliver to Borrower evidence of any such release, as reasonably requested by, and at the expense of, Borrower.

Upon the occurrence of an Event of Default described in subsection (h)(i), (h)(ii) or (h)(iii) of this section: all Obligations shall thereupon be immediately due and payable, without demand, presentment, notice of demand or of dishonor and nonpayment, protest, notice of protest, notice of intention to accelerate, declaration or notice of acceleration, or any other notice or declaration of any kind, all of which are hereby expressly waived by Borrower and each Restricted Person who at any time ratifies or approves this Agreement. Upon any such acceleration, any obligation of any Lender to make any further Loans shall be permanently terminated. During the continuance of any other Event of Default, Administrative Agent at any time and from time to time may (and upon written instructions from Majority Lenders, Administrative Agent shall), without notice to Borrower or any other Restricted Person, do either or both of the following: (1) terminate or suspend any obligation of Lenders to make Loans hereunder, and (2) declare any or all of the Obligations immediately due and payable, and all such Obligations shall thereupon be immediately due and payable, without demand, presentment, notice of demand or of dishonor and nonpayment, protest, notice of protest, notice of intention to accelerate, declaration or notice of acceleration, or any other notice or declaration of any kind, all of which are hereby expressly waived by Borrower and each Restricted Person who at any time ratifies or approves this Agreement.

Section 8.2. Remedies. If any Default shall occur and be continuing, each Lender Party may protect and enforce its rights under the Loan Documents by any appropriate proceedings, including proceedings for specific performance of any covenant or agreement contained in any Loan Document, and each Lender Party may enforce the payment of any Obligations due it or enforce any other legal or equitable right which it may have. All rights, remedies and powers conferred upon Lender Parties under the Loan Documents shall be deemed cumulative and not exclusive of any other rights, remedies or powers available under the Loan Documents or at Law or in equity.

ARTICLE IX—Administrative Agent

Section 9.1. Appointment and Authority. Each Lender Party hereby irrevocably authorizes Administrative Agent, and Administrative Agent hereby undertakes, to receive payments of principal, interest and other amounts due hereunder as specified herein and to take all other actions and to exercise such powers under the Loan Documents as are specifically delegated to Administrative Agent by the terms hereof or thereof, together with all other powers reasonably incidental thereto. The relationship of Administrative Agent to the other Lender Parties is only that of one commercial lender acting as administrative agent for others, and nothing in the Loan Documents shall be construed to constitute Administrative Agent a trustee or other fiduciary for any Lender Party or any holder of any participation in a Note nor to impose on Administrative Agent duties and obligations other than those expressly provided for in the Loan Documents. With respect to any matters not expressly provided for in the Loan Documents and any matters which the Loan Documents place within the discretion of Administrative Agent, Administrative Agent shall not be required to exercise any discretion or take any action, and it may request instructions from Lenders with respect to any such matter, in which case it shall be required to act or to refrain from acting (and shall be fully protected and free from liability to all Lender Parties in so acting or refraining from acting) upon the instructions of Majority Lenders (including itself), provided, however, that Administrative Agent shall not be required to take any action which exposes it to a risk of personal liability that it considers unreasonable or which is contrary to the Loan Documents or to applicable Law. Upon receipt by Administrative Agent from Borrower of any communication calling for action on the part of Lenders or upon notice from Borrower or any Lender to Administrative Agent of any Default or Event of Default, Administrative Agent shall promptly notify each other Lender thereof.

Section 9.2. Exculpation, Administrative Agent's Reliance, Etc. Neither Administrative Agent nor any of its directors, officers, agents, attorneys, or employees shall be liable for any action taken or

omitted to be taken by any of them under or in connection with the Loan Documents, INCLUDING THEIR NEGLIGENCE OF ANY KIND, except that each shall be liable for its own gross negligence or willful misconduct. Without limiting the generality of the foregoing, Administrative Agent (a) may treat the payee of any Note as the holder thereof until Administrative Agent receives written notice of the assignment or transfer thereof in accordance with this Agreement, signed by such payee and in form satisfactory to Administrative Agent; (b) may consult with legal counsel (including counsel for Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any other Lender Party and shall not be responsible to any other Lender Party for any statements, warranties or representations made in or in connection with the Loan Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of the Loan Documents on the part of any Restricted Person or to inspect the property (including the books and records) of any Restricted Person; (e) shall not be responsible to any other Lender Party for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document or any instrument or document furnished in connection therewith; (f) may rely upon the representations and warranties of each Restricted Person or Lender Party in exercising its powers hereunder; and (g) shall incur no liability under or in respect of the Loan Documents by acting upon any notice, consent, certificate or other instrument or writing (including any facsimile, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper Person or Persons.

Section 9.3. Credit Decisions. Each Lender Party acknowledges that it has, independently and without reliance upon any other Lender Party, made its own analysis of Borrower and the transactions contemplated hereby and its own independent decision to enter into this Agreement and the other Loan Documents. Each Lender Party also acknowledges that it will, independently and without reliance upon any other Lender Party and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Loan Documents.

Section 9.4. INDEMNIFICATION. EACH LENDER AGREES TO INDEMNIFY ADMINISTRATIVE AGENT (TO THE EXTENT NOT REIMBURSED BY BORROWER WITHIN TEN (10) DAYS AFTER DEMAND) FROM AND AGAINST SUCH LENDER'S PERCENTAGE SHARE OF ANY AND ALL LIABILITIES, OBLIGATIONS, CLAIMS, LOSSES, DAMAGES, PENALTIES, FINES, ACTIONS, JUDGMENTS, SUITS, SETTLEMENTS, COSTS, EXPENSES OR DISBURSEMENTS (INCLUDING REASONABLE FEES OF ATTORNEYS, ACCOUNTANTS, EXPERTS AND ADVISORS) OF ANY KIND OR NATURE WHATSOEVER (IN THIS SECTION COLLECTIVELY CALLED "LIABILITIES AND COSTS") WHICH TO ANY EXTENT (IN WHOLE OR IN PART) MAY BE IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST ADMINISTRATIVE AGENT GROWING OUT OF, RESULTING FROM OR IN ANY OTHER WAY ASSOCIATED WITH THE LOAN DOCUMENTS AND THE TRANSACTIONS AND EVENTS (INCLUDING THE ENFORCEMENT THEREOF) AT ANY TIME ASSOCIATED THEREWITH OR CONTEMPLATED THEREIN AND BORROWER'S USE OF LOAN PROCEEDS (WHETHER ARISING IN CONTRACT OR IN TORT OR OTHERWISE AND INCLUDING ANY VIOLATION OR NONCOMPLIANCE WITH ANY ENVIRONMENTAL LAWS BY ANY PERSON OR ANY LIABILITIES OR DUTIES OF ANY PERSON WITH RESPECT TO HAZARDOUS MATERIALS FOUND IN OR RELEASED INTO THE ENVIRONMENT).

Administrative Agent's own individual gross negligence or willful misconduct, as determined in a final judgment. Cumulative of the foregoing, each Lender agrees to reimburse Administrative Agent promptly upon demand for such Lender's Percentage Share of any costs and expenses to be paid to Administrative Agent by Borrower under Section 10.4(a) to the extent that Administrative Agent is not timely reimbursed for such expenses by Borrower as provided in such section. As used in this section the term "Administrative Agent" shall refer not only to the Persons designated as such in Section 1.1 but also to each director, officer, agent, attorney, employee, representative and Affiliate of such Person.

Section 9.5. Rights as Lender. In its capacity as a Lender, Administrative Agent shall have the same rights and obligations as any Lender and may exercise such rights as though it were not Administrative Agent. Administrative Agent may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with any Restricted Person or their Affiliates, all as if it were not Administrative Agent hereunder and without any duty to account therefor to any other Lender.

Section 9.6. Sharing of Set-Offs and Other Payments. Each Lender Party agrees that if it shall, whether through the exercise of rights of banker's lien, set off, or counterclaim against Borrower or otherwise, obtain payment of a portion of the aggregate Obligations owed to it which, taking into account all distributions made by Administrative Agent under Section 3.1, causes such Lender Party to have received more than it would have received had such payment been received by Administrative Agent and distributed pursuant to Section 3.1, then (a) it shall be deemed to have simultaneously purchased and shall be obligated to purchase interests in the Obligations as necessary to cause all Lender Parties to share all payments as provided for in Section 3.1, and (b) such other adjustments shall be made from time to time as shall be equitable to ensure that Administrative Agent and all Lender Parties share all payments of Obligations as provided in Section 3.1; provided, however, that nothing herein contained shall in any way affect the right of any Lender Party to obtain payment (whether by exercise of rights of banker's lien, set-off or counterclaim or otherwise) of indebtedness other than the Obligations. Borrower expressly consents to the foregoing arrangements, subject to Section 10.9. If all or any part of any funds transferred pursuant to this section is thereafter recovered from the seller under this section which received the same, the purchase provided for in this section shall be deemed to have been rescinded to the extent of such recovery, together with interest, if any, if interest is required pursuant to the order of a Tribunal to be paid on account of the possession of such funds prior to such recovery.

Section 9.7. Investments. Whenever Administrative Agent in good faith determines that it is uncertain about how to distribute to Lender Parties any funds which it has received, or whenever Administrative Agent in good faith determines that there is any dispute among Lender Parties about how such funds should be distributed, Administrative Agent may choose to defer distribution of the funds which are the subject of such uncertainty or dispute. If Administrative Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if Administrative Agent is otherwise required to invest funds pending distribution to Lender Parties, Administrative Agent shall invest such funds pending distribution; all interest on any such Investment shall be distributed upon the distribution of such Investment and in the same proportion and to the same Persons as such Investment. All moneys received by Administrative Agent for distribution to Lender Parties (other than to the Person who is Administrative Agent in its separate capacity as a Lender Party) shall be held by Administrative Agent pending such distribution solely as Administrative Agent for such Lender Parties, and Administrative Agent shall have no equitable title to any portion thereof.

Section 9.8. Benefit of Article IX. The provisions of this Article are intended solely for the benefit of Lender Parties, and no Restricted Person shall be entitled to rely on any such provision or assert any such provision in a claim or defense against any Lender (other than contained in Section 9.6 or the right to reasonably approve a successor Administrative Agent under Section 9.9). Lender Parties

may waive or amend such provisions as they desire without any notice to or consent of Borrower or any other Restricted Person.

Section 9.9. Resignation. Administrative Agent may resign at any time by giving written notice thereof to Lenders and Borrower. Each such notice shall set forth the date of such resignation. Upon any such resignation Majority Lenders shall have the right to appoint a successor Administrative Agent, subject to the approval of Borrower, unless a Default has occurred and is continuing, which approval will not be unreasonably withheld. A successor must be appointed for any retiring Administrative Agent, and such Administrative Agent's resignation shall become effective when such successor accepts such appointment. If, within thirty days after the date of the retiring Administrative Agent's resignation, no successor Administrative Agent has been appointed and has accepted such appointment, then the retiring Administrative Agent may appoint a successor Administrative Agent, which shall be a commercial bank organized or licensed to conduct a banking or trust business under the Laws of the United States of America or of any state thereof. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. After any retiring Administrative Agent's resignation hereunder the provisions of this Article IX shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under the Loan Documents.

Section 9.10. Other Agents. Neither the Syndication Agent nor the Documentation Agent ("Co-Agents"), in such capacities, shall have any duties or responsibilities or incur any liabilities in such agency capacities (as opposed to its capacity as a Lender) under or in connection with this Agreement or under any of the other Loan Documents. The relationship between Borrower on the one hand, and the Co-Agents and the Agents, on the other hand, shall be solely that of borrower and lender. None of the Co-Agents shall have any fiduciary responsibilities to Borrower or any of their respective Affiliates. None of the Co-Agents undertakes any responsibility to Borrower or any of their respective Affiliates to review or inform any such Person of any matter in connection with any phase of such Person's or such Affiliate's business or operations.

ARTICLE X—Miscellaneous

Section 10.1. Waivers and Amendments; Acknowledgments.

(a) Waivers and Amendments. No failure or delay (whether by course of conduct or otherwise) by any Lender in exercising any right, power or remedy which such Lender Party may have under any of the Loan Documents shall operate as a waiver thereof or of any other right, power or remedy, nor shall any single or partial exercise by any Lender Party of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy. No waiver of any provision of any Loan Document and no consent to any departure therefrom shall ever be effective unless it is in writing and signed as provided below in this section, and then such waiver or consent shall be effective only in the specific instances and for the purposes for which given and to the extent specified in such writing. This Agreement and the other Loan Documents set forth the entire understanding between the parties hereto with respect to the transactions contemplated herein and therein and supersede all prior discussions and understandings with respect to the subject matter hereof and thereof, and no waiver, consent, release, modification or amendment of or supplement to this Agreement or the other Loan Documents shall be valid or effective against any party hereto unless the same is in writing and signed by (i) if such party is Borrower, by Borrower, (ii) if such party is Administrative Agent, by Administrative Agent, and (iii) if such party is a Lender, by such Lender or by Administrative Agent on behalf of Lenders with the written consent of Majority Lenders (which consent has already been given as to the termination of the Loan Documents as provided in Section 10.10). Notwithstanding the foregoing or anything to the contrary herein, Administrative Agent shall not,

without the prior consent of each individual Lender, execute and deliver on behalf of such Lender any waiver or amendment which would: (1) waive any of the conditions specified in Article IV (provided that Administrative Agent may in its discretion withdraw any request it has made under Section 4.1(i)), (2) increase the maximum amount which such Lender is committed hereunder to lend, or extend the termination date of such Lender's commitment to lend, (3) reduce any fees payable to such Lender hereunder, or the principal of, or interest on, such Lender's Note, (4) change any date fixed for any payment of any such fees, principal or interest, or change Section 9.6 in a manner that would alter pro rata sharing of payments required thereby, (5) amend the definition herein of "Majority Lenders" or otherwise change the Percentage Shares which are required for Administrative Agent, Lenders or any of them to take any particular action under the Loan Documents, or (6) except as expressly provided herein or in any other Loan Document, release (i) Borrower from its obligation to pay such Lender's Note, (ii) any Guarantor from its guaranty of such payment or (iii) any Restricted Person from the negative pledge covenant set forth in Section 7.11 hereof.

(b) Acknowledgments and Admissions. Borrower hereby represents, warrants, acknowledges and admits that (i) it has been advised by counsel in the negotiation, execution and delivery of the Loan Documents to which it is a party, (ii) no Lender Party has any fiduciary obligation toward Borrower with respect to any Loan Document or the transactions contemplated thereby, (iii) the relationship pursuant to the Loan Documents between Borrower and the other Restricted Persons, on one hand, and each Lender Party, on the other hand, is and shall be solely that of debtor and creditor, respectively, and (iv) no partnership or joint venture exists with respect to the Loan Documents between any Restricted Person and any Lender Party.

(c) Representation by Lenders. Each Lender hereby represents that it will acquire its Notes for its own account in the ordinary course of its commercial lending or investing business; however, the disposition of such Lender's property shall at all times be and remain within its control and, in particular and without limitation, such Lender may sell or otherwise transfer its Note, any participation interest or other interest in its Note, or any of its other rights and obligations under the Loan Documents subject to compliance with Sections 10.5(b) through (f), inclusive, and applicable Law.

(d) JOINT ACKNOWLEDGMENT. THIS WRITTEN AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

Section 10.2. Survival of Agreements; Cumulative Nature. All of Restricted Persons' various representations, warranties, covenants and agreements in the Loan Documents shall survive the execution and delivery of this Agreement and the other Loan Documents and the performance hereof and thereof, including the making or granting of the Loans and the delivery of the Notes and the other Loan Documents, and shall further survive until all of the Obligations are paid in full to each Lender Party and all of Lender Parties' obligations to Borrower are terminated. The rights, powers, and privileges granted to Lender Parties in the Loan Documents, are cumulative, and, except for expressly specified waivers and consents, no Loan Document shall be construed in the context of another to diminish, nullify, or otherwise reduce the benefit to any Lender Party of any such right, power or privilege.

Section 10.3. Notices. All notices, requests, consents, demands and other communications required or permitted under any Loan Document shall be in writing, unless otherwise specifically provided in such Loan Document (provided that Administrative Agent may give telephonic notices to the other Lender Parties), and shall be deemed sufficiently given or furnished if delivered by personal

delivery, by facsimile or other electronic transmission, by delivery service with proof of delivery, or by registered or certified United States mail, postage prepaid, to Borrower and Restricted Persons at the address of Borrower specified on the signature pages hereto and to each Lender Party at its address specified on the signature pages hereto (unless changed by similar notice in writing given by the particular Person whose address is to be changed). Any such notice or communication shall be deemed to have been given (a) in the case of personal delivery or delivery service, as of the date of first attempted delivery during normal business hours at the address provided herein, (b) in the case of facsimile or other electronic transmission, upon receipt, or (c) in the case of registered or certified United States mail, three days after deposit in the mail; provided, however, that no Borrowing Notice or Continuation/Conversion Notice shall become effective until actually received by Administrative Agent.

Section 10.4. Payment of Expenses; Indemnity.

(a) Payment of Expenses. Whether or not the transactions contemplated by this Agreement are consummated, Borrower will promptly (and in any event, within 30 days after any invoice or other statement or notice) pay: (i) all transfer, stamp, mortgage, documentary or other similar taxes, assessments or charges levied by any governmental or revenue authority in respect of this Agreement or any of the other Loan Documents or any other document referred to herein or therein, (ii) all reasonable costs and expenses incurred by or on behalf of Administrative Agent (including attorneys' fees, consultants' fees and engineering fees, travel costs and miscellaneous expenses) in connection with (1) the negotiation, preparation, execution and delivery of the Loan Documents, and any and all consents, waivers or other documents or instruments relating thereto, (2) the filing, recording, refiling and re-recording of any Loan Documents and any other documents or instruments or further assurances required to be filed or recorded or refiled or re-recorded by the terms of any Loan Document, (3) the borrowings hereunder and other action reasonably required in the course of administration hereof, (4) monitoring or confirming (or preparation or negotiation of any document related to) Borrower's compliance with any covenants or conditions contained in this Agreement or in any Loan Document, and (iii) all reasonable costs and expenses incurred by or on behalf of any Lender Party (including attorneys' fees, consultants' fees and accounting fees) in connection with the defense or enforcement of any of the Loan Documents (including this section) or the defense of any Lender Party's exercise of its rights thereunder. In addition to the foregoing, until all Obligations have been paid in full, Borrower will also pay or reimburse Administrative Agent for all reasonable out-of-pocket costs and expenses of Administrative Agent or its agents or employees in connection with the continuing administration of the Loans and the related due diligence of Administrative Agent, including travel and miscellaneous expenses and fees and expenses of Administrative Agent's outside counsel and consultants engaged in connection with the Loan Documents.

(b) Indemnity. Borrower agrees to indemnify each Lender Party, upon demand, from and against any and all liabilities, obligations, claims, losses, damages, penalties, fines, actions, judgments, suits, settlements, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this section collectively called "liabilities and costs") which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against such Lender Party growing out of, resulting from or in any other way associated with the Loan Documents and the transactions and events (including the enforcement or defense thereof) at any time associated therewith or contemplated therein and Borrower's use of Loan proceeds (whether arising in contract or in tort or otherwise and including any violation or noncompliance with any Environmental Laws by any Lender Party or any other Person or any liabilities or duties of any Lender Party or any other Person with respect to Hazardous Materials found in or released into the environment).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY OR CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY LENDER PARTY, provided only that no Lender Party shall be entitled under this section to receive indemnification for that portion, if any, of any liabilities and costs which is proximately caused by its own individual gross negligence or willful misconduct, as determined in a final judgment. If any Person (including Borrower or any of its Affiliates) ever alleges such gross negligence or willful misconduct by any Lender Party, the indemnification provided for in this section shall nonetheless be paid upon demand, subject to later adjustment or reimbursement, until such time as a court of competent jurisdiction enters a final judgment as to the extent and effect of the alleged gross negligence or willful misconduct. As used in this section the term "Lender Party" shall refer not only to each Person designated as such in Section 1.1 but also to each director, officer, trustee, agent, attorney, employee, representative and Affiliate of such Persons.

(c) Interest. Borrower hereby promises to each Lender Party interest at the Default Rate on all Obligations to pay fees or to reimburse or indemnify any Lender Party which Borrower has promised to pay to such Lender Party pursuant to this Section 10.4 and which are not paid when due. Such interest shall accrue from the date such Obligations become due until they are paid.

Section 10.5. Joint and Several Liability; Parties in Interest; Assignments; Replacement Notes.

(a) All Obligations which are incurred by two or more Restricted Persons shall be their joint and several obligations and liabilities of such Restricted Persons. All grants, covenants and agreements contained in the Loan Documents shall bind and inure to the benefit of the parties thereto and their respective successors and permitted assigns; provided, however, that no Restricted Person may assign or transfer any of its rights or delegate any of its duties or obligations under any Loan Document without the prior consent of all Lenders. Neither Borrower nor any Affiliates of Borrower shall directly or indirectly purchase or otherwise retire any Obligations owed to any Lender nor will any Lender accept any offer to do so, unless each Lender shall have received substantially the same offer with respect to the same Percentage Share of the Obligations owed to it. If Borrower or any Affiliate of Borrower at any time purchases some but less than all of the Obligations owed to all Lender Parties, such purchaser shall not be entitled to any rights of any Lender under the Loan Documents unless and until Borrower or its Affiliates have purchased all of the Obligations.

(b) No Lender shall sell any participation interest in its commitment hereunder or any of its rights under its Loans or under the Loan Documents to any Person unless the agreement between such Lender and such participant at all times provides: (i) that such participation exists only as a result of the agreement between such participant and such Lender and that such transfer does not give such participant any right to vote as a Lender or any other direct claims or rights against any Person other than such Lender, (ii) that such participant is not entitled to payment from any Restricted Person under Sections 3.2 through 3.6 of amounts in excess of those payable to such Lender under such sections (determined without regard to the sale of such participation), and (iii) unless such participant is an Affiliate of such Lender, that such participant shall not be entitled to require such Lender to take any action under any Loan Document or to obtain the consent of such participant prior to taking any action under any Loan Document, except for actions which would require the consent of all Lenders under subsection (a) of Section 10.1. No Lender selling such a participation shall, as between the other parties hereto and such Lender, be relieved of any of its obligations hereunder as a result of the sale of such participation. Each Lender which sells any such participation to any Person (other than an Affiliate of such Lender) shall give prompt notice thereof to Administrative Agent and Borrower; provided, however, that no liability shall arise if any such Lender fails to give such notice to Borrower.

(c) Except for sales of participations under the immediately preceding subsection, no Lender shall make any assignment or transfer of any kind of its commitments or any of its rights under its Loans or

under the Loan Documents, except for assignments to an Eligible Transferee or, subject to the provisions of subsection (g) below, to an affiliate, and then only if such assignment is made in accordance with the following requirements:

(i) In the case of an assignment by a Lender of less than all of its Loans and Commitment, each such assignment shall apply to a consistent percentage of all Loans owing to the assignor Lender hereunder and to the same percentage of the unused portion of the assignor Lender's Commitment, so that after such assignment is made both the assignee Lender and the assignor Lender shall have a fixed (and not a varying) Percentage Share in its Loans and be committed to make that Percentage Share of all future Loans, and the Percentage Share of such Commitment of each of the assignor and assignee shall equal or exceed $5,000,000.

(ii) The parties to each such assignment shall execute and deliver to Administrative Agent, for its acceptance and recording in the "Register" (as defined below in this section), an Assignment and Acceptance in the form of Exhibit F, appropriately completed, together with the Note subject to such assignment and a processing fee payable by such assignor Lender (and not at Borrower's expense) to Administrative Agent of $3,500. Upon such execution, delivery, and payment and upon the satisfaction of the conditions set out in such Assignment and Acceptance, then (i) Borrower shall issue new Notes to such assignor and assignee upon return of the old Notes to Borrower, and (ii) as of the "Settlement Date" specified in such Assignment and Acceptance the assignee thereunder shall be a party hereto and a Lender hereunder and Administrative Agent shall thereupon deliver to Borrower and each Lender a revised Schedule 1 hereto showing the revised Percentage Shares and total Percentage Shares of such assignor Lender and such assignee Lender and the revised Percentage Shares and total Percentage Shares of all other Lenders.

(iii) Each assignee Lender which is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) for Federal income tax purposes, shall (to the extent it has not already done so) provide Administrative Agent and Borrower with the "Prescribed Forms" referred to in Section 3.7(d).

(d) Any Lender may at any time pledge all or any portion of its Loan and Note (and related rights under the Loan Documents including any portion of its Note) to any of the twelve (12) Federal Reserve Banks organized under Section 4 of the Federal Reserve Act, 12 U.S.C. Section 341. No such pledge or enforcement thereof shall release any such Lender from its obligations under any of the Loan Documents; provided that all related costs, fees and expenses in connection with any such pledge shall be for the sole account of such Lender.

(e) By executing and delivering an Assignment and Acceptance, each assignee Lender thereunder will be confirming to and agreeing with Borrower, Administrative Agent and each other Lender Party that such assignee understands and agrees to the terms hereof, including Article IX hereof.

(f) Administrative Agent shall maintain a copy of each Assignment and Acceptance and a register for the recordation of the names and addresses of Lenders and the Percentage Shares of, and principal amount of the Loans owing to, each Lender from time to time (in this section called the "Register"). The entries in the Register shall be conclusive, in the absence of manifest error, and Borrower and each Lender Party may treat each Person whose name is recorded in the Register as a Lender Party hereunder for all purposes. The Register shall be available for inspection by Borrower or any Lender Party at any reasonable time and from time to time upon reasonable prior notice.

(g) Any Lender may assign or transfer its commitment or its rights under its Loans or under the Loan Documents to (i) any Affiliate that is wholly-owned direct or indirect subsidiary of such Lender or of any Person that wholly owns, directly or indirectly, such Lender, or (ii) if such Lender is a fund that makes or invests in bank loans, any other fund that makes or invests in bank loans and is advised

or managed by (A) the same investment advisor as any Lender or (B) any Affiliate of such investment advisor that is a wholly-owned direct or indirect subsidiary of any Person that wholly owns, directly or indirectly, such investment advisor, subject to the following additional conditions (x), (y) and (z), with respect to assignments pursuant to clause (i) above, and subject to the following additional conditions (y) and (z) with respect to assignments pursuant to clause (ii) above:

(x) any right of such Lender assignor and such assignee to vote as a Lender, or any other direct claims or rights against any other Persons, shall be uniformly exercised by both such assignor and assignee or pursued in the manner that such Lender assignor would have so exercised such vote, claim or right if it had not made such assignment or transfer;

(y) such assignee shall not be entitled to payment from any Restricted Person under Sections 3.2 through 3.7 of amounts in excess of those payable to such Lender assignor under such sections (determined without regard to such assignment or transfer); and

(z) if such Lender assignor is a Lender that assigns or transfers to such assignee any of such Lender Commitment, assignee may become primarily liable for such Commitment, but such assignment or transfer shall not relieve or release such Lender from such Commitment.

(h) Upon receipt of an affidavit reasonably satisfactory to Borrower of an officer of any Lender as to the loss, theft, destruction or mutilation of its Note which is not of public record, and, in the case of any such loss, theft, destruction or mutilation, upon cancellation of such Note, Borrower will execute and deliver, in lieu thereof, a replacement Note in the same principal amount thereof and otherwise of like tenor.

Section 10.6. Confidentiality. Each Lender Party agrees (on behalf of itself and each of its Affiliates, and each of its and their directors, officers, agents, attorneys, employees, and representatives) that it (and each of them) will take all reasonable steps to keep confidential any non-public information supplied to it by or at the direction of any Restricted Person so identified when delivered, provided, however, that this restriction shall not apply to (a) information which has at the time in question entered the public domain, other than as a result of a breach of this Section 10.6, (b) information which is required to be disclosed by Law (whether valid or invalid) of any Tribunal, (c) any disclosure to any Lender Party's Affiliates, auditors, attorneys or agents (provided each such Person first agrees to hold such information in confidence on the terms provided in this Section 10.6), (d) any disclosure to any other Lender Party or to any purchaser or prospective purchaser of participations or other interests in any Loan or Loan Document (provided each such Person first agrees to hold such information in confidence on the terms provided in this section), or (e) any disclosure in the course of enforcing its rights and remedies during the existence of an Event of Default.

Section 10.7. Governing Law; Submission to Process. EXCEPT TO THE EXTENT THAT THE LAW OF ANOTHER JURISDICTION IS EXPRESSLY ELECTED IN A LOAN DOCUMENT, THE LOAN DOCUMENTS SHALL BE DEEMED CONTRACTS AND INSTRUMENTS MADE UNDER THE LAWS OF THE STATE OF NEW YORK AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK AND THE LAWS OF THE UNITED STATES OF AMERICA, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. BORROWER HEREBY AGREES THAT ANY LEGAL ACTION OR PROCEEDING AGAINST BORROWER WITH RESPECT TO THIS AGREEMENT, THE NOTES OR ANY OF THE LOAN DOCUMENTS MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK AS LENDER PARTIES MAY ELECT, AND, BY EXECUTION AND DELIVERY HEREOF, BORROWER ACCEPTS AND CONSENTS FOR ITSELF AND IN RESPECT TO ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE NON-EXCLUSIVE JURISDICTION OF THE AFORESAID COURTS. EACH BORROWER AGREES THAT SECTIONS 5-1401 AND 5-1402 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK SHALL APPLY TO THE LOAN DOCUMENTS AND WAIVES ANY RIGHT TO STAY OR TO DISMISS ANY ACTION OR PROCEEDING BROUGHT BEFORE SAID COURTS ON THE BASIS OF FORUM NON CONVENIENS. IN FURTHERANCE OF THE FOREGOING, BORROWER HEREBY IRREVOCABLY DESIGNATES AND APPOINTS

CORPORATION SERVICE COMPANY, ▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, AS AGENT OF BORROWER TO RECEIVE SERVICE OF ALL PROCESS BROUGHT AGAINST BORROWER WITH RESPECT TO ANY SUCH PROCEEDING IN ANY SUCH COURT IN NEW YORK, SUCH SERVICE BEING HEREBY ACKNOWLEDGED BY BORROWER TO BE EFFECTIVE AND BINDING SERVICE IN EVERY RESPECT.

Section 10.8. Limitation on Interest. Lender Parties, Restricted Persons and any other parties to the Loan Documents intend to contract in strict compliance with applicable usury Law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Loan Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be contracted for, charged, or received by applicable Law from time to time in effect. Neither any Restricted Person nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum amount that may be lawfully contracted for, charged, or received under applicable Law from time to time in effect, and the provisions of this section shall control over all other provisions of the Loan Documents which may be in conflict or apparent conflict herewith. Lender Parties expressly disavow any intention to contract for, charge, or receive excessive unearned interest or finance charges in the event the maturity of any Obligation is accelerated. If (a) the maturity of any Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) any Lender or any other holder of any or all of the Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted to be contracted for, charged or received by applicable Law then in effect, then all sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, at such Lender's or holder's option, promptly returned to Borrower or other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific circumstance, exceeds the maximum amount permitted under applicable Law, Lender Parties and Restricted Persons (and any other payors thereof) shall to the greatest extent permitted under applicable Law, (i) characterize any non-principal payment as an expense, fee or premium rather than as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Obligations in accordance with the amounts outstanding from time to time thereunder and the maximum legal rate of interest from time to time in effect under applicable Law in order to lawfully charge the maximum amount of interest permitted under applicable Law. In the event applicable Law provides for an interest ceiling under Chapter 303 of the Texas Finance Code (the "Texas Finance Code") as amended, to the extent that the Texas

Finance Code is mandatorily applicable to any Lender, for that day, the ceiling shall be the "weekly ceiling" as defined in the Texas Finance Code, provided that if any applicable Law permits greater interest, the Law permitting the greatest interest shall apply. In no event shall Chapter 346 of the Texas Finance Code apply to this Agreement or any other Loan Document, or any transactions or loan arrangement provided or contemplated hereby or thereby.

Section 10.9. Right of Offset. At any time and from time to time during the continuance of any Event of Default, each Lender is hereby authorized to offset against the Obligations then due and payable (without notice to any Restricted Person), (a) any and all moneys, securities or other property (and the proceeds therefrom) of such Restricted Person now or hereafter held or received by or in transit to any Lender from or for the account of such Restricted Person, whether for safekeeping, custody, pledge, transmission, collection or otherwise, (b) any and all deposits (general or special, time or demand, provisional or final) of such Restricted Person with any Lender, and (c) any other credits and claims of such Restricted Person at any time existing against any Lender, including claims under certificates of deposit.

Section 10.10. Termination; Limited Survival. In its sole and absolute discretion Borrower may at any time that no Obligations are owing or outstanding elect in a written notice delivered to Administrative Agent to terminate this Agreement. Upon receipt by Administrative Agent of such a notice, if no Obligations are then owing or outstanding this Agreement and all other Loan Documents shall thereupon be terminated and the parties thereto released from all prospective obligations thereunder. Notwithstanding the foregoing or anything herein to the contrary, any waivers or admissions made by any Restricted Person in any Loan Document, any Obligations under Sections 3.2 through 3.6, and any obligations which any Person may have to indemnify or compensate any Lender Party shall survive any termination of this Agreement or any other Loan Document. At the request and expense of Borrower, Administrative Agent shall prepare and execute all necessary instruments to reflect and effect such termination of the Loan Documents. Administrative Agent is hereby authorized to execute all such instruments on behalf of all Lenders, without the joinder of or further action by any Lender.

Section 10.11. Severability. If any term or provision of any Loan Document shall be determined to be illegal or unenforceable all other terms and provisions of the Loan Documents shall nevertheless remain effective and shall be enforced to the fullest extent permitted by applicable Law.

Section 10.12. Counterparts. This Agreement may be separately executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to constitute one and the same Agreement.

Section 10.13. Waiver of Jury Trial, Punitive Damages, etc. RESTRICTED PERSONS AND LENDER PARTIES MUTUALLY HEREBY KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED HEREON, ARISING OUT OF, UNDER OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENTS CONTEMPLATED TO BE EXECUTED IN CONNECTION HEREWITH OR ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY. THIS WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR LENDERS TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND MAKE THE LOANS. BORROWER AND EACH LENDER PARTY HEREBY FURTHER (A) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY "SPECIAL DAMAGES," AS DEFINED BELOW, (B) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (C) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION. AS

USED IN THIS SECTION, "SPECIAL DAMAGES" INCLUDES ALL SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES (REGARDLESS OF HOW NAMED), BUT DOES NOT INCLUDE ANY PAYMENTS OR FUNDS WHICH ANY PARTY HERETO HAS EXPRESSLY PROMISED TO PAY OR DELIVER TO ANY OTHER PARTY HERETO.
