ARTICLE II—The Loans

Section 2.1. Commitments to Lend; Notes. Subject to the terms and conditions hereof, each Lender agrees to make loans to Borrower (herein called such Lender's "Loans") upon Borrower's request from time to time prior to the Maturity Date, provided that after giving effect to such Loans, the aggregate

outstanding amount of Loans does not exceed the Borrowing Base determined as of the date on which the requested Loans are to be made. The aggregate amount of all Loans in any Borrowing must be greater than or equal to $1,000,000 or must equal the remaining availability under the Borrowing Base. The obligation of Borrower to repay to each Lender the aggregate amount of all Loans made by such Lender, together with interest accruing in connection therewith, shall be evidenced by a single promissory note (herein called such Lender's "Note") made by Borrower payable to the order of such Lender in the form of Exhibit A with appropriate insertions. The amount of principal owing on any Lender's Note at any given time shall be the aggregate amount of all Loans theretofore made by such Lender minus all payments of principal theretofore received by such Lender on such Note. Interest on each Note shall accrue and be due and payable as provided herein and therein. Each Note shall be due and payable as provided herein and therein, and shall be due and payable in full on the Maturity Date. Subject to the terms and conditions hereof, Borrower may borrow, repay, and reborrow hereunder.

Section 2.2. Requests for New Loans. Borrower must give to Agent written notice (or telephonic notice promptly confirmed in writing) of any requested Borrowing of new Loans to be advanced by Lenders. Each such notice constitutes a "Borrowing Notice" hereunder and must:

(a) specify (i) the aggregate amount of any such Borrowing of new Base Rate Loans and the date on which such Base Rate Loans are to be advanced, or (ii) the aggregate amount of any such Borrowing of new Eurodollar Loans, the date on which such Eurodollar Loans are to be advanced (which shall be the first day of the Interest Period which is to apply thereto), and the length of the applicable Interest Period; and

(b) be received by Agent not later than 10:00 a.m., New York, New York time, on (i) the day on which any such Base Rate Loans are to be made, or (ii) the third Business Day preceding the day on which any such Eurodollar Loans are to be made.

Each such written request or confirmation must be made in the form and substance of the "Borrowing Notice" attached hereto as Exhibit B, duly completed. Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. Upon receipt of any such Borrowing Notice, Agent shall give each Lender prompt notice of the terms thereof. If all conditions precedent to such new Loans have been met, each Lender will on the date requested promptly remit to Agent at Agent's office in New York, New York the amount of such Lender's new Loan in immediately available funds, and upon receipt of such funds, unless to its actual knowledge any conditions precedent to such Loans have been neither met nor waived as provided herein, Agent shall promptly make such Loans available to Borrower. Unless Agent shall have received prompt notice from a Lender that such Lender will not make available to Agent such Lender's new Loan, Agent may in its discretion assume that such Lender has made such Loan available to Agent in accordance with this section and Agent may if it chooses, in reliance upon such assumption, make such Loan available to Borrower. If and to the extent such Lender shall not so make its new Loan available to Agent, such Lender and Borrower severally agree to pay or repay to Agent within three days after demand the amount of such Loan together with interest thereon, for each day from the date such amount was made available to Borrower until the date such amount is paid or repaid to Agent, with interest at (i) the Federal Funds Rate, if such Lender is making such payment and (ii) the interest rate applicable at the time to the other new Loans made on such date, if Borrower is making such repayment. If neither such Lender nor Borrower pays or repays to Agent such amount within such three-day period, Agent shall in addition to such amount be entitled to recover from such Lender and from Borrower, on demand, interest thereon at the Default Rate applicable to Base Rate Loans, calculated from the date such amount was made available to Borrower. The failure of any Lender to make any new Loan to be made by it hereunder shall not relieve any other Lender of its obligation hereunder, if any, to make its new Loan, but no Lender shall be responsible for the failure of any other Lender to make any new Loan to be made by such other Lender.

Section 2.3. Continuations and Conversions of Existing Loans. Borrower may make the following elections with respect to Loans already outstanding: to convert Base Rate Loans to Eurodollar Loans, to convert Eurodollar Loans to Base Rate Loans on the last day of the Interest Period applicable thereto, and to continue Eurodollar Loans beyond the expiration of such Interest Period by designating a new Interest Period to take effect at the time of such expiration. In making such elections, Borrower may combine existing Loans made pursuant to separate Borrowings into one new Borrowing or divide existing Loans made pursuant to one Borrowing into separate new Borrowings, provided that Borrower may have no more than three Borrowings of Eurodollar Loans outstanding at any time. To make any such election, Borrower must give to Agent written notice (or telephonic notice promptly confirmed in writing) of any such Conversion or Continuation of existing Loans, with a separate notice given for each new Borrowing. Each such notice constitutes a "Continuation/Conversion Notice" hereunder and must:

(a) specify the existing Loans which are to be Continued or Converted;

(b) specify (i) the aggregate amount of any Borrowing of Base Rate Loans into which such existing Loans are to be continued or converted and the date on which such Continuation or Conversion is to occur, or (ii) the aggregate amount of any Borrowing of Eurodollar Loans into which such existing Loans are to be continued or converted, the date on which such Continuation or Conversion is to occur (which shall be the first day of the Interest Period which is to apply to such Eurodollar Loans), and the length of the applicable Interest Period; and

(c) be received by Agent not later than 10:00 a.m., New York, New York time, on (i) the day on which any such Continuation or Conversion to Base Rate Loans is to occur, or (ii) the third Business Day preceding the day on which any such Continuation or Conversion to Eurodollar Loans is to occur.

Each such written request or confirmation must be made in the form and substance of the "Continuation/Conversion Notice" attached hereto as Exhibit C, duly completed. Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. Upon receipt of any such Continuation/Conversion Notice, Agent shall give each Lender prompt notice of the terms thereof. Each Continuation/Conversion Notice shall be irrevocable and binding on Borrower. During the continuance of any Default, Borrower may not make any election to convert existing Loans into Eurodollar Loans or continue existing Loans as Eurodollar Loans. 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 Eurodollar Loans at least three days prior to the end of the Interest Period applicable thereto, such Eurodollar Loans 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 already outstanding Loans.

Section 2.4. Use of Proceeds. Borrower shall use all Loans to finance capital expenditures, finance acquisitions permitted pursuant to Section 7.7, and provide working capital for its operations and for other general business purposes. In no event shall the funds from any Loan be used directly or indirectly by any Person for personal, family, household or agricultural purposes or for the purpose, whether immediate, incidental or ultimate, of purchasing, acquiring or carrying any "margin stock" (as such term is defined in Regulation U promulgated by the Board of Governors of the Federal Reserve System) or to extend credit to others directly or indirectly for the purpose of purchasing or carrying any such margin stock. Borrower represents and warrants that Borrower is not engaged principally, or as one of Borrower's important activities, in the business of extending credit to others for the purpose of purchasing or carrying such margin stock.

Section 2.5. Interest Rates and Fees.

(a) Interest Rates. As provided in the Notes: (i) each Base Rate Loan shall bear interest on each day outstanding at the Adjusted Base Rate in effect on such day, (ii) each Eurodollar Loan shall bear interest on each day during the related Interest Period at the related Adjusted Eurodollar Rate in effect on such day, and (iii) if an Event of Default has occurred and is continuing, all Loans shall bear interest on each day outstanding at the applicable Default Rate. Past due payments of principal and interest shall bear interest at the rates and in the manner set forth in the Notes.

(b) Commitment Fees. In consideration of each Lender's commitment to make Loans, Borrower will pay to Agent for the account of each Lender a commitment fee determined on a daily basis by applying a rate of [***]* to such Lender's Percentage Share of the unused portion of the Maximum Credit Amount on each day prior to the Maturity Date, determined for each such day by deducting from the amount of the Maximum Credit Amount at the end of such day the outstanding principal amount of the Loans. This commitment fee shall be due and payable in arrears on the last day of each Fiscal Quarter and on the Maturity Date. Notwithstanding the foregoing, if during any Fiscal Quarter, any Lender (a "Defaulting Lender") fails to make available a Loan, has not cured such failure and no Default or Event of Default was continuing on the date of such failure, Borrower shall have no obligation to pay the Defaulting Lender its commitment fee for such Fiscal Quarter until such time as the Defaulting Lender makes available such Loan.

(c) Fees. In addition to all other amounts due to Agent under the Loan Documents, Borrower will pay to Agent the fees described in a letter agreement of even date herewith between Agent and Borrower.

Section 2.6. Mandatory Prepayments.

(a) If at any time the aggregate outstanding amount of the Loans exceeds the Borrowing Base, Borrower shall immediately upon demand prepay the principal of the Loans in an amount at least equal to such excess.

(b) Borrower understands and agrees that for a period of not less than fourteen (14) consecutive days during each Fiscal Year, Borrower shall have repaid the aggregate outstanding amount of the Loans, together with all accrued but unpaid interest thereon.

(c) Borrower shall immediately prepay the principal of the Loans in an amount equal to the proceeds (net of expenses) from either of the following:

(i) additional equity issuances of Borrower; and

(ii) any sale, transfer, assignment or other disposition of any property, rights, assets or business of any Restricted Person (but without waiving the requirements of Majority Lenders' consent to any sale, transfer, assignment or other disposition in violation of any Loan Document), except proceeds of any sale, transfer, assignment or other disposition of property which is permitted by Section 7.5 (a) or Section 7.5(b).

(d) Each prepayment of principal under this section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid. Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment.

Section 2.7. Optional Prepayments. Borrower may, upon five Business Days' notice to each Lender, from time to time and without premium or penalty prepay the Notes, in whole or in part, so long as the aggregate amounts of all partial prepayments of principal on the Notes equals $1,000,000 or any higher integral multiple of $1,000,000, so long as Borrower does not prepay any Eurodollar Loan, and so long as Borrower does not make any prepayments which would reduce the unpaid principal balance of any Loan to less than $100,000 without first either (a terminating this Agreement or (b) providing assurance satisfactory to Agent in its discretion that Lenders' legal rights under the Loan Documents are in no way affected by such reduction; provided that Borrower may prepay any Eurodollar Loan so long as such prepayment shall be accompanied by all reimbursement amounts payable pursuant to Section 3.5. Each prepayment of principal under this section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid. Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment.

ARTICLE III—Payments to Lenders

Section 3.1. General Procedures. Borrower will make each payment which it owes under the Loan Documents to Agent for the account of the Lender Party to whom such payment is owed, in lawful money of the United States of America, without set-off, deduction or counterclaim, and in immediately available funds. Each such payment must be received by Agent not later than 11:00 a.m., New York, New York time, on the date such payment becomes due and payable. Any payment received by Agent after such time will be deemed to have been made on the next following Business Day.

Each payment under a Loan Document 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 Agent's Note. When Agent collects or receives money on account of the Obligations, Agent shall distribute all money so collected or received, and each Lender Party shall apply all such money so distributed, as follows:

(a) 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 Agent under Section 6.9 or 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);

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

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

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

All distributions of amounts described in any of subsections (b), (c) or (d) above shall be made by 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 Agent under Section 9.9, any amounts otherwise distributable under this section to such Lender shall be deemed to belong to Agent, to the extent of such unpaid payments, and 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, upon demand by such Lender Party, Borrower will pay to 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 Eurodollar 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 Eurodollar Loan or otherwise due under this Agreement in respect of any Eurodollar Loan (other than taxes imposed on 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 Eurodollar 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 Eurodollar Loan, the result of which is to increase the cost to any Lender Party of funding or maintaining any Eurodollar Loan or to reduce the amount of any sum receivable by any Lender Party in respect of any Eurodollar Loan by an amount deemed by such Lender Party to be material,

then such Lender Party shall promptly notify 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 pay such amount to Agent for the account of such Lender Party and (ii) Borrower may elect, by giving to Agent and such Lender Party not less than three Business Days' notice, to convert all (but not less than all) of any such Eurodollar Loans into Base Rate Loans.

Section 3.4. 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 Eurodollar 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 Eurodollar 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, then, upon notice by such Lender Party to Borrower and Agent, Borrower's right to elect Eurodollar Loans from such Lender Party shall be suspended to the extent and for the duration of such illegality, impracticability or restriction and all Eurodollar 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. Borrower agrees to indemnify each Lender Party and hold it 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 3.5. Funding Losses. In addition to its other obligations hereunder, Borrower will indemnify each Lender Party 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 a Lender Party to fund or maintain Eurodollar Loans), as a result of (a) any payment or prepayment (whether authorized or required hereunder or otherwise) of all or a portion of a Eurodollar Loan on a day other than the day on which the applicable Interest Period ends, (b) any payment or prepayment, whether required hereunder or otherwise, 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 authorized or required hereunder or otherwise) of all or any portion of any Eurodollar Loan into a Base Rate Loan or into a different Eurodollar 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. Notwithstanding the foregoing, Borrower shall not be obligated to pay any claim for compensation pursuant to this Section 3.5 arising or accruing more than nine (9) months prior to the date Borrower is notified of the applicable Lender Party's demand for such compensation.

Section 3.6. Reimbursable Taxes. Borrower covenants and agrees that:

(a) Borrower will indemnify each Lender Party against and reimburse each Lender Party for all present and future income, stamp and other taxes, levies, costs and charges whatsoever imposed, assessed, levied or collected on or in respect of this Agreement or any Eurodollar 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 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 Lender Party's Loans and Note, and all other amounts payable by Borrower to any 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 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 Eurodollar Loan, Borrower may elect, by giving to Agent and such Lender Party not less than three Business Days' notice, to convert all (but not less than all) of any such Eurodollar 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 any Lender Party, other than a Lender Party (i) who is a U.S. person for Federal income tax purposes or (ii) who has the Prescribed Forms on file with Agent (with copies provided to 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 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 the Lender Party providing the forms or statements, (y) the Internal Revenue 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 3.7. Change of Applicable Lending Office. Each Lender Party agrees that, upon the occurrence of any event giving rise to the operation of Sections 3.2 through 3.6 with respect to such Lender Party, it will, if requested by Borrower, use reasonable efforts (subject to overall policy considerations of such Lender Party) to designate another Applicable Lending Office, provided that such designation is made on such terms that such Lender Party and its Applicable Lending Office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of any such section. Nothing in this section shall affect or postpone any of the obligations of Borrower or the rights of any Lender Party provided in Sections 3.2 through 3.6.

Section 3.8. Replacement of Lenders. If any Lender Party seeks reimbursement for increased costs under Sections 3.2 through 3.6, 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 Notes and its commitments hereunder to an Eligible Transferee reasonably acceptable to Agent and to Borrower, provided that: (a) all Obligations of Borrower owing to such Lender Party being replaced (including such increased costs, but excluding principal and accrued interest on the Notes being assigned) shall be paid in full to such Lender Party concurrently with such assignment, and (b) the replacement Eligible Transferee shall purchase the Note being assigned by paying to such Lender Party a price equal to the principal amount thereof plus accrued and unpaid interest thereon. In connection with any such assignment Borrower, 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 3.6 unless Borrower is at the same time replacing all Lender Parties which are then seeking such compensation.

The relationship of 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 Agent a trustee or other fiduciary for any Lender Party or any holder of any participation in a Note nor to impose on 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 Agent, 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 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 Agent from Borrower of any communication calling

for action on the part of Lenders or upon notice from any other Lender to Agent of any Default or Event of Default, Agent shall promptly notify each other Lender thereof.

Section 9.2. Exculpation, Agent's Reliance, Etc.

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 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 Agent growing out of, resulting from or in any other way associated with any of the Collateral, the Loan Documents and the transactions and events (including the enforcement thereof) at any time associated therewith or contemplated therein (whether arising in contract or in tort and 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 Substances 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 ARE CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY AGENT,

provided only that no Lender shall be obligated under this section to indemnify Agent for that portion, if any, of any liabilities and costs which is proximately caused by Agent's own individual gross

negligence or willful misconduct, as determined in a final judgment. Cumulative of the foregoing, each Lender agrees to reimburse Agent promptly upon demand for such Lender's Percentage Share of any costs and expenses to be paid to Agent by Borrower under Section 10.4(a) to the extent that Agent is not timely reimbursed for such expenses by Borrower as provided in such section. As used in this section the term "Agent" shall refer not only to the Person 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, Agent shall have the same rights and obligations as any Lender and may exercise such rights as though it were not Agent. 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 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 under Security Documents or 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 Agent under Section 3.1, causes such Lender Party to have received more than it would have received had such payment been received by 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 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 and agrees that any holder of any such interest or other participation in the Obligations, whether or not acquired pursuant to the foregoing arrangements, may to the fullest extent permitted by Law exercise any and all rights of banker's lien, set-off, or counterclaim as fully as if such holder were a holder of the Obligations in the amount of such interest or other participation. 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 order to be paid on account of the possession of such funds prior to such recovery.

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

Section 9.8. Benefit of Article IX. The provisions of this Article (other than the following Section 9.9) 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. Lender Parties may waive or amend such provisions as they desire without any notice to or consent of Borrower or any Restricted Person.

Section 9.9. Resignation. 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 Agent. A successor must be appointed for any retiring Agent, and such Agent's resignation shall become effective when such successor accepts such appointment. If, within thirty days after the date of the retiring Agent's

resignation, no successor Agent has been appointed and has accepted such appointment, then the retiring Agent may appoint a successor 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 Agent hereunder by a successor Agent, the retiring Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. After any retiring 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 Agent under the Loan Documents.

Section 9.10 Certain Titles. Notwithstanding any other provision of this Agreement or any of the other Loan Documents, any Lenders designated on the cover page of this Agreement or elsewhere herein as "Syndication Agent," "Co-Agent" or any similar designation are named as such for recognition purposes only, and in their capacities as such shall have no powers, rights, duties, responsibilities or liabilities with respect to this Agreement and the other Loan Documents and the transactions contemplated hereby and thereby.

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. No notice to or demand on any Restricted Person shall in any case of itself entitle any Restricted Person to any other or further notice or demand in similar or other circumstances. 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 Agent, by such party, and (iii) if such party is a Lender, by such Lender or by 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 10.9). Notwithstanding the foregoing or anything to the contrary herein, 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 Agent may in its discretion withdraw any request it has made under Section 4.2(g)), (2) increase the maximum amount which such Lender is committed hereunder to lend, (3) reduce any fees payable to such Lender hereunder, or the principal of, or interest on, such Lender's Note, (4) postpone any date fixed for any payment of any such fees, principal or interest, (5) amend the definition herein of "Majority Lenders" or otherwise change the aggregate amount of Percentage Shares which is required for Agent, Lenders or any of them to take any particular action under the Loan Documents, (6) release Borrower from its obligation to pay such Lender's Note or any Guarantor from its guaranty of such payment, (7) release all or substantially all of the Collateral, or (8) amend this Section 10.1(a).

(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) it has made an independent decision to enter into this Agreement and the other Loan Documents to which it is a party, without reliance on any representation, warranty, covenant or undertaking by Agent or any Lender, whether written, oral or implicit, other than as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iii) there are no representations, warranties, covenants, undertakings or agreements by any Lender as to the Loan Documents except as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iv) no Lender has any fiduciary obligation toward Borrower with respect to any Loan Document or the transactions contemplated thereby, (v) the relationship pursuant to the Loan Documents between Borrower and the other Restricted Persons, on one hand, and each Lender, on the other hand, is and shall be solely that of debtor and creditor, respectively, (vi) no partnership or joint venture exists with respect to the Loan Documents between any Restricted Person and any Lender, (vii) Agent is not Borrower's Agent, but Agent for Lenders, (viii) should an Event of Default or Default occur or exist, each Lender will determine in its sole discretion and for its own reasons what remedies and actions it will or will not exercise or take at that time, (ix) without limiting any of the foregoing, Borrower is not relying upon any representation or covenant by any Lender, or any representative thereof, and no such representation or covenant has been made, that any Lender will, at the time of an Event of Default or Default, or at any other time, waive, negotiate, discuss, or take or refrain from taking any action permitted under the Loan Documents with respect to any such Event of Default or Default or any other provision of the Loan Documents, and (x) all Lender Parties have relied upon the truthfulness of the acknowledgments in this section in deciding to execute and deliver this Agreement and to become obligated hereunder.

(c) 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. All statements and agreements contained in any certificate or other instrument delivered by any Restricted Person to any Lender Party under any Loan Document shall be deemed representations and warranties by Borrower or agreements and covenants of Borrower under this Agreement. The representations, warranties, indemnities, and covenants made by Restricted Persons in the Loan Documents, and 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 representation, warranty, indemnity, covenant, right, power or privilege. In particular and without limitation, no exception set out in this Agreement to any representation, warranty, indemnity, or covenant herein contained shall apply to any similar representation, warranty, indemnity, or covenant contained in any other Loan Document, and each such similar representation, warranty, indemnity, or covenant shall be subject only to those exceptions which are expressly made applicable to it by the terms of the various Loan Documents.

Section 10.3. Notices. All notices, demands, approvals, consents and other communications to be made under any Loan Document to or by the parties thereto must, to be effective for purpose of such Loan Document, be in writing. Notices, demands and other communications required or permitted

under any Loan Document are to be sent 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 Lenders Schedule and shall be given by any of the following means: (A) personal service, with proof of delivery or attempted delivery retained; (B) electronic communication, whether by telex, telegram or telecopying (if confirmed in writing sent by United States first class mail, return receipt requested); or (C) registered or certified first class mail, return receipt requested. Such addresses may be changed by notice to the other parties given in the same manner as provided above. Any notice or other communication sent pursuant to clause (A) or (B) hereof shall be deemed received upon such personal service or upon dispatch by electronic means, and, if sent pursuant to clause (C) shall be deemed received five days following deposit in the mail; provided, however, that no Borrowing Notice shall become effective until actually received by 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 or transaction referred to herein or therein, (ii) all reasonable costs and expenses incurred by or on behalf of Agent (including without limitation 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) any Restricted Person'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 without limitation attorneys' fees, consultants' fees and accounting fees) in connection with the defense or enforcement of any of the Loan Documents (including this section), any attempt to cure any breach thereunder by any Restricted Person, 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 Agent for all reasonable out-of-pocket costs and expenses of Agent or its agents or employees in connection with the continuing administration of the Loans and the related due diligence of Agent, including travel and miscellaneous expenses and fees and expenses of Agent's outside counsel, reserve engineers 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, broker's fees, 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 any of the Collateral, the Loan Documents and the transactions and events (including the enforcement or defense thereof) at any time associated therewith or contemplated therein (whether arising in contract or in tort or otherwise). Among other things, the foregoing indemnification covers all liabilities and costs incurred by any Lender Party related to any breach of a Loan Document by a Restricted Person, any bodily injury to any Person or damage to any Person's property, or 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 Substances 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, agent, trustee, attorney, employee, representative and Affiliate of or for such Person.

Notwithstanding the foregoing, for purposes of this section, Losses will not include and Borrower will not be required to pay (i) income taxes on the interest accruing on, or the fee income required to be paid in connection with, the Loans, or (ii) legal fees or other costs incurred or suffered by anyone other than Agent in connection with the negotiation or execution of this Agreement or in connection with due diligence undertaken before the execution of this Agreement. Losses will include, however, income taxes payable by any Lender Party because of Borrower's payment or reimbursement of other Losses suffered by such Lender Party, to the extent (if any) such additional taxes are not offset by tax savings to such Lender Party because of the other Losses paid or reimbursed by Borrower.

Further, if any Lender Party receives a refund of Losses paid on its behalf or reimbursed to it by Borrower pursuant to this section, such Lender Party shall promptly shall pay to Borrower the amount of such refund, plus or minus any net tax benefits or detriments realized by such Lender Party as a result of such refund and such payment to Borrower; provided, that the amount payable to Borrower shall not exceed the amount of the indemnity payment in respect of such refunded Losses that was made by Borrower. If it is subsequently determined that the Lender Party was not entitled to the refund, the portion of such refund that is repaid or recaptured will be treated as a Loss for which Borrower must indemnify such Lender Party pursuant to this section. If, in connection any such refund, a Lender Party also receives an amount representing interest on the refund, the Lender Party shall promptly pay to Borrower the amount of such interest, plus or minus any net tax benefits or detriments realized by the Lender Party as a result of the receipt or accrual of such interest and as a result of the such payment to Borrower; provided, that no Lender Party will be required to make any such payment in respect of the interest (if any) that is fairly attributable to a period before Borrower paid for or reimbursed the Losses refunded. As used in this paragraph, the term "tax benefit" will not include a reduction of taxes that are subject to indemnification by Borrower pursuant to this section except to the extent (if any) that Borrower has previously paid or reimbursed such taxes. As used in this paragraph, the term "refund" shall be deemed to include credits to the extent they actually reduce taxes that would otherwise be payable by the Lender Party receiving such credits and that are not subject to indemnification by Borrower pursuant to this section. Notwithstanding the foregoing, in no event shall any Lender Party be required to make any payment to Borrower pursuant to the foregoing provisions when any Event of Default has occurred and is continuing.

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

(a) All Obligations which are incurred by two or more Restricted Persons shall be their joint and several obligations and liabilities. 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 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 Majority 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 Agent and 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, and then only if such assignment is made in accordance with the following requirements:

(i) Each such assignment shall apply to all Obligations owing to the assignor Lender hereunder and to the unused portion of the assignor Lender's commitments, so that after such assignment is made the assignor Lender shall have a fixed (and not a varying) Percentage Share in its Loans and Note and be committed to make that Percentage Share of all future Loans, the assignee shall have a fixed Percentage Share in such Loans and Note and be committed to make that Percentage Share of all future Loans, and the Percentage Share of the Maximum Credit Amount of both the assignor and assignee shall equal or exceed $5,000,000.

(ii) The parties to each such assignment shall execute and deliver to 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 to Agent of $2,500. Upon such execution, delivery, and payment and upon the satisfaction of the conditions set out in such Assignment and Acceptance, then (1) Borrower shall issue new Notes to such assignor and assignee upon return of the old Notes to Borrower, and (2) as of the "Settlement Date" specified in such Assignment and Acceptance the assignee thereunder shall be a party hereto and a Lender hereunder and Agent shall thereupon deliver to Borrower and each Lender a schedule showing the revised Percentage Shares of such assignor Lender and such assignee Lender and the 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 Internal Revenue Code) for Federal income tax purposes, shall (to the extent it has not already done so) provide Agent and Borrower with the "Prescribed Forms" referred to in Section 3.6(d).

(d) Nothing contained in this section shall prevent or prohibit any Lender from assigning or pledging all or any portion of its Loans and Note to any Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank; provided that no such assignment or pledge shall relieve such Lender from its obligations hereunder.

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

(f) 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 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.

Section 10.6. Confidentiality. Agent and each Lender (each, a "Lending Party") agrees to keep confidential any information furnished or made available to it by any Restricted Person pursuant to this Agreement that is marked confidential; provided that nothing herein shall prevent any Lending Party from disclosing such information (a) to any other Lending Party or any Affiliate of any Lending Party, or any officer, director, employee, agent, or advisor of any Lending Party or Affiliate of any Lending Party, (b) to any other Person if reasonably incidental to the administration of the credit facility provided herein, (c) as required by any Law, (d) upon the order of any court or administrative agency, (e) upon the request or demand of any Tribunal, (f) that is or becomes available to the public or that is or becomes available to any Lending Party other than as a result of a disclosure by any Lending Party prohibited by this Agreement, (g) in connection with any litigation to which such Lending Party or any of its Affiliates may be a party, (h) to the extent necessary in connection with the exercise of any right or remedy under this Agreement or any other Loan Document, and (i) subject to provisions substantially similar to those contained in this section, to any actual or proposed participant or assignee.

Section 10.7. Governing Law. 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 California and shall be construed and enforced in accordance with and governed by the Laws of the State of California and the Laws of the United States of America, without regard to principles of conflicts of law.

Section 10.8. Limitation on Interest. Lender Parties, Restricted Persons and the 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 provide for 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.

Section 10.9. Termination; Limited Survival. In its sole and absolute discretion Borrower may at any time that no Obligations are owing elect in a written notice delivered to Agent to terminate this Agreement. Upon receipt by Agent of such a notice, if no Obligations are then owing 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, Agent shall prepare and execute all necessary instruments to reflect and effect such termination of the Loan Documents. 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 10.10. Severability. If any term or provision of any Loan Document or the application thereof shall to any extent be held by a court of competent jurisdiction to be invalid and unenforceable, the remainder of such document, or the application of such term or provision other than to the extent to which it is invalid or unenforceable, shall not be affected thereby.

Section 10.11. Counterparts; Fax. 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. This Agreement and the Loan Documents may be validly executed and delivered by facsimile or other electronic transmission.

Section 10.12. Waiver of Jury Trial, Punitive Damages, etc. Borrower and each Lender Party hereby knowingly, voluntarily, intentionally, and irrevocably (a) waives, to the maximum extent not prohibited by Law, any right it may have to a trial by jury in respect of any litigation based hereon, or directly or indirectly at any time arising out of, under or in connection with the Loan Documents or any transaction contemplated thereby or associated therewith, before or after maturity; (b 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, (c) 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 (d) 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.

IN WITNESS WHEREOF, this Agreement is executed as of the date first written above.
