Neither the Project nor any Property of the Company nor the operations currently conducted thereon by the Company or UNS Electric or, to the actual knowledge of the Company, by any prior owner or operator thereof, violate any applicable order of any court or other Governmental Authority or applicable Environmental Laws, which violation could reasonably be expected to have a Material Adverse Effect or could reasonably be expected to result in remedial obligations having a Material Adverse Effect assuming disclosure to the applicable Governmental Authority of all relevant facts, conditions and circumstances, if any, pertaining to the Project or the relevant Property.

Without limitation of subsection (a) above, neither the Project nor any Property of the Company nor the operations currently conducted thereon by the Company or UNS Electric or, to the actual knowledge of the Company, by any prior owner or operator thereof, are the subject of any existing, pending or, to the knowledge of the Company, threatened action, suit, investigation, inquiry or proceeding by or before any court or other Governmental Authority or subject to any remedial obligations under applicable Environmental Laws, which action, suit, investigation, inquiry or proceeding could reasonably be expected to have a Material Adverse Effect or could reasonably be expected to result in remedial obligations having a Material Adverse Effect assuming disclosure to the applicable Governmental Authority of all relevant facts, conditions and circumstances, if any, pertaining to the Project or the relevant Property.

(c) Notices, Permits, etc. All notices, permits, licenses or similar authorizations, if any, required to be obtained or filed by the Company in connection with the ownership, operation or use of the Project, and any and all other Property of the Company, including but not limited to present, or, to the actual knowledge of the Company, past, treatment, storage, disposal or release of any Hazardous Materials into the environment, have been duly obtained or filed, except to the extent the failure to obtain or file such notices, permits, licenses or similar authorizations could not reasonably be expected to have a Material Adverse Effect and could not reasonably be expected to result in remedial obligations having a Material Adverse Effect assuming disclosure to the applicable Governmental Authority of all relevant facts, conditions and circumstances, if any, pertaining to the Project or the relevant Property.

The present value of all accumulated benefit obligations under each Plan (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of such Plan by an amount that has resulted or could reasonably be expected to result in a Guarantor Material Adverse Effect. The present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of all such underfunded Plans by an amount that has resulted or could reasonably be expected to result in a Guarantor Material Adverse Effect.

SECTION 2.17 Disclosure. None of this Agreement, any other Financing Document or any writing (other than the Base Case Projections) furnished to the Agent or any other Secured Party by or on behalf of the Company in connection herewith or therewith contains any untrue statement of a material fact, and such Financing Documents and writings, taken as a whole, do not omit to state a material fact necessary in order to make the statements contained herein and therein, in light of the circumstances under which they were made, not misleading. There is no fact known to the Company which materially adversely affects, or in the future could reasonably be expected to materially adversely affect, the business, property, assets or financial condition of the Company or the ability of the Company to perform its obligations under the Transaction Documents which has not been set forth in this Agreement, in the other Financing Documents or in other documents furnished to the Agent by or on behalf of the Company prior to the date hereof in connection with the transactions contemplated hereby. The historical financial information contained in the Base Case Projections is true and correct. The financial projections contained in the Base Case Projections were (i) to the extent prepared by the Company, prepared in good faith based upon assumptions that were reasonable at the time such projections were prepared, and (ii) to the extent prepared by a Person other than the Company, to the best of the Company’s knowledge, prepared in good faith based upon assumptions that were reasonable at the time such projections were prepared.

SECTION 2.18 Subsidiaries. The Company has no Subsidiaries.

SECTION 2.19 No Default. The Company is not in default under or with respect to any Project Document or other material agreement, lease or instrument to which the Company is a party or by which it or its Properties may be bound. To the actual knowledge of the Company, no other party to any Project Document is in default under any material covenant or obligation set forth therein. No Default has occurred and is continuing.

SECTION 2.20 Taxes. The Company has filed or caused to be filed all tax returns that are required to be filed, and has paid all taxes shown to be due and payable on said returns or on any assessments made against the Company or any of its assets and all other taxes, fees or other charges imposed on the Company by any Governmental Authority (other than taxes and assessments the payment of which are being contested in good faith by the Company and adequate reserves, in the aggregate, for the payment of which have been set aside) and no tax Liens (other than Permitted Liens) have been filed and no claims are being asserted with respect to any such taxes, fees or other charges.

SECTION 2.21 Delivery of Project Documents. The Agent has received a true and complete copy of each Project Document (including all exhibits, schedules and disclosure letters referred to therein or delivered pursuant thereto, if any, and any and all amendments or modifications thereto). Except as permitted pursuant to Section 9.06 hereof, none of the Project Documents has been amended, modified or terminated, and all of the Project Documents are in full force and effect. Except for the Project Documents, the Financing Documents and the other agreements listed in Schedule III hereto, the Company is not a party to any contract, indenture, mortgage, instrument or other agreement that (a) evidences or secures Debt of the Company or any Affiliate of the Company in each case having a principal amount (contingent or otherwise) that exceeds $2,000,000 or (b) exceeds $2,000,000 per annum in value (“value” being defined as the greater of (i) amounts payable by the Company thereunder in any calendar year or (ii) the value of the goods and services (including, without limitation, any cash) received by the Company thereunder in any calendar year (as reasonably determined by the Company)).

SECTION 2.22 Financial Condition. The unaudited balance sheet and related statements of income and cash flows of the Company for the fiscal year ended December 31, 2008 and the most recent financial statements delivered by the Company pursuant to Section 8.09(a) hereof present fairly, in all material respects, the financial position and results of operations and cash flows of the Company as of such dates and for such periods in accordance with GAAP, as applied on a consistent basis, subject to year-end audit adjustments and the absence of footnotes in the case of the statements delivered pursuant to Section 8.09(a) hereof. The Company did not have, at the date of the most recent balance sheet referred to above, any guarantee, contingent liability or liability for taxes, or any long-term lease or unusual forward or long-term commitment, including any interest rate or foreign currency swap or exchange transaction, which, in any case, was material to the Company and which was not reflected in the foregoing statements or in the notes thereto. During the period from December 31, 2008 to and including the Closing Date there has been no sale, transfer or other disposition by the Company of any part of its business or Property, and, except as set forth in Schedule V hereto, no purchase or other acquisition of any business or Property (including any equity interests of any other Person), which, in either case, is material in relation to the financial condition of the Company at December 31, 2008. Since December 31, 2008, there has been no event or change in facts or circumstances affecting the Company or the Project that individually or in the aggregate has had or could reasonably be expected to have a Material Adverse Effect.

(b) If the Agent shall determine, in good faith, that adequate and reasonable means do not exist for ascertaining the Adjusted LIBOR Rate for any Eurodollar Rate Loans,

(i) the Agent shall forthwith notify the Company and the Banks as promptly as practicable that the interest rate cannot be determined for such Eurodollar Rate Loans and any request for a Eurodollar Rate Loan shall be deemed to be a request for an Alternate Base Rate Loan hereunder,

(a) Optional Prepayments. The Company may, subject to Section 6.03 hereof, prepay the Loans in whole or in part in the aggregate principal amount of $1,000,000 or an integral multiple of $500,000 in excess thereof, upon at least three (3) Business Days’ prior written notice by the Company to the Agent in the case of Eurodollar Rate Loans and at least one (1) Business Day’s prior written notice to the Agent in the case of Alternate Base Rate Loans (in each case, each such notice to the Agent to be irrevocable), specifying the date and amount of such prepayment, and whether the prepayment is of Eurodollar Rate Loans or Alternate Base Rate Loans (or a combination thereof). If such notice is given, the Company shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein, together with accrued interest to such date on the amount prepaid and any amount payable pursuant to Section 6.03 hereof (but without any other premium or penalty). Subject to the terms and conditions of this Agreement, the Company may borrow Loans under Section 3.01 hereof and prepay any such Loans to the extent permitted by this Section 4.02(a).

(b) Mandatory Payments and Prepayments.

(i) Repayment at Maturity. On the Termination Date, the Company shall repay in full the outstanding principal amount of the Loans, together with accrued and unpaid interest thereon, and all other Obligations payable to the Banks under this Agreement and the other Financing Documents.

(ii) Excess Cash Flow. (A) No later than the date that occurs twenty (20) Business Days after each Quarterly Date, the Company shall prepay the outstanding principal amount of the Loans in an amount equal to 100% of the Excess Cash Flow for the calendar quarter ended on such Quarterly Date, calculated on the basis of preliminary financial statements for such calendar quarter. On or before the date of each such prepayment pursuant to subclauses (A) and (B) hereof, the Company will furnish to the Agent a certificate of an Authorized Officer of the Company setting forth reasonably detailed calculations of such Excess Cash Flow; and (B) together with the unaudited quarterly financial statements delivered pursuant to Section 8.09(a) hereof, the Company shall prepay the outstanding principal amount of the Loans in an amount equal to the excess of (1) Excess Cash Flow calculated on the basis of such quarterly financial statements over (2) Excess Cash Flow as previously calculated pursuant to Section 4.02(b)(ii)(A) hereof. If the Company shall have previously overpaid amounts owing under Section 4.02(b)(ii)(A), the Company shall deliver a certificate of an Authorized Officer of the Company setting forth reasonably detailed calculations showing such overpayment, and shall be entitled to subtract such amount from the next payment or prepayment (as the case may be) required to be made pursuant to this Section 4.02(b), and the Agent shall apply such amounts to the next payment or prepayment, accordingly. Any prepayments pursuant to this Section 4.02(b)(ii) shall be rounded downwards, if necessary, to the nearest $1,000.

(iii) All prepayments required by this subsection (b) shall be applied, in accordance with Section 4.02(c), to outstanding Alternate Base Rate Loans up to the full amount thereof before they are applied to outstanding Eurodollar Rate Loans. Each prepayment under this subsection (b) shall be accompanied by (A) accrued interest to the date of such prepayment on the principal amount prepaid and (B) in the case of prepayments of Eurodollar Rate Loans (subject to the application of Section 4.02(e) hereof), any amount payable to the applicable Banks pursuant to Section 6.03 hereof (but without any other premium or penalty).

(c) Application of Prepayments. If the amount of any payment or prepayment on a Loan is less than the sum of (i) the outstanding principal amount of such Loan and (ii) interest accrued on such Loan to the date of such payment or prepayment, the amounts paid or prepaid on such Loan shall be applied first to accrued interest and then to principal.

(d) Payments through Agent. All payments by the Company to the Banks under this Section 4.02 shall be made through the Agent.

(e) Prepayment Account. So long as no Event of Default shall have occurred and be continuing, on a date: (i) that is not the last day of an Interest Period applicable to Eurodollar Rate Loans outstanding, (ii) on which a prepayment pursuant to Section 4.02(b)(ii) exceeds the amount of all Alternate Base Rate Loans outstanding (such excess being referred to herein as the “Eurodollar Rate Loan Prepayment Amount”) and (iii) on which the prepayment of any outstanding Eurodollar Rate Loans would result in any compensation becoming due and payable by the Company to any Bank pursuant to Section 6.03 hereof (it being understood and agreed that the condition set forth in this clause (iii) shall be deemed to be satisfied unless each Bank has, on or before such date, notified the Company and the Agent in writing that either (x) such prepayment will not result in any such compensation becoming due and payable to such Bank or (y) such Bank waives any such compensation with respect to such prepayment), the Agent shall automatically deposit the Eurodollar Rate Loan Prepayment Amount in a separate Prepayment Account (as defined below) for such outstanding Eurodollar Rate Loans. The Agent shall apply any cash deposited in the Prepayment Account to prepay Eurodollar Rate Loans on the last day of their respective Interest Periods (or, at the direction of the Company, on any earlier date, and in any event no later than the Termination Date) until all outstanding Eurodollar Rate Loans have been prepaid or until all the allocable cash on deposit in the Prepayment Account has been exhausted. For purposes of this Agreement, the term “Prepayment Account” shall mean the cash collateral account established by the Company with the Agent, bearing Account No. 0000000000, over which the Agent shall have exclusive dominion and control, including the exclusive right of withdrawal for application in accordance with this subsection (e). The Prepayment Account shall not bear interest and all amounts on deposit therein shall be maintained in cash. If the maturity of the Loans has been accelerated pursuant to Section 10 hereof, the Agent may, in its sole discretion, apply such funds to satisfy any of the Obligations. To secure the timely payment and performance of the Obligations, the Company does hereby pledge and assign to the Agent for the benefit of the Secured Parties, and does hereby grant to the Agent for the benefit of the Secured Parties a continuing security interest in and lien on, all the estate, right, title and interest of the Company, whether now owned or hereafter existing or acquired, in, to and under the Prepayment Account and all funds from time to time on deposit therein (the “Prepayment Account Collateral”).

SECTION 4.03 Lending Office. Loans of each Type shall be made and maintained at each Bank’s Applicable Lending Office for such Type of Loan.

SECTION 4.04 Pro Rata Treatment. Except as otherwise provided herein, each Borrowing of Loans shall be made among the Banks pro rata according to there respective Proportionate Shares, and payment of principal of and interest on the Loans shall be made pro rata among the Banks according to the respective unpaid principal amounts of the Loans held by the Banks.

SECTION 4.05 Interest Rates. The Company shall pay interest on the unpaid principal amount of each Loan made by each Bank from the date of such Loan until such principal amount shall be paid in full, at one of the following rates per annum:

(a) Alternate Base Rate Loans. If such Loan is an Alternate Base Rate Loan, a rate per annum equal at all times to the sum of the Alternate Base Rate in effect from time to time plus the Applicable Margin;

(b) Eurodollar Rate Loans. If such Loan is a Eurodollar Rate Loan, a rate per annum equal at all times during each Interest Period for such Loan to the sum of the Adjusted LIBOR Rate for such Interest Period for such Loan plus the Applicable Margin; and

(c) Post-Default Interest. Notwithstanding the foregoing, the Company will pay interest at the applicable Post-Default Rate on any principal of any Loan, and (to the fullest extent permitted by law) any other amount payable by the Company hereunder or under any Note, which shall not be paid when due (whether at stated maturity, by acceleration or otherwise), for the period commencing on the due date thereof until the same is paid in full.

SECTION 4.06 Payment Dates. Interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan, provided that interest payable at the Post-Default Rate shall be payable from time to time on demand of the Agent.

SECTION 4.07 Maximum Interest. Notwithstanding anything to the contrary contained in this Agreement or any other Financing Document, the interest paid or agreed to be paid under this Agreement and the Notes shall not exceed the maximum rate of non-usurious interest permitted by the laws of any state of applicable jurisdiction as the same may be modified by Federal law (the “Maximum Rate”). If the Agent or any Bank shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans owing to such Bank or, if it exceeds such unpaid principal, refunded to the Company. In determining whether the interest contracted for, charged, or received by the Agent or a Bank exceeds the Maximum Rate, such Person may, to the extent permitted by applicable law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

SECTION 4.08 Notes. The Loans made or to be made by each Bank shall be evidenced by a single promissory note (each, a “Note”) of the Company in substantially the form of Exhibit A hereto, dated the Closing Date, payable to such Bank in a principal amount equal to the Commitment of such Bank as originally in effect and otherwise duly completed. All Loans made by each Bank and all payments and prepayments made on account of the principal thereof, and all Conversions of such Loans, shall be recorded by such Bank on the schedule (or a continuation thereof) attached to the respective Note held by it evidencing such Loans, it being understood, however, that failure by such Bank to make any such endorsement shall not affect the obligations of the Company hereunder or under such Note in respect of such Loans evidenced thereby.

SECTION 4.09 Termination by Company. The Company may terminate this Agreement upon payment in full of all amounts then owing to the Banks and the Agent on the Loans, the Notes and all other Obligations, subject to Section 4.02(a) hereof; provided, however, that no such termination shall be effective until all such amounts have been paid in full and all outstanding Interest Rate Protection Agreements to which any Secured Party is a party have expired or been terminated.

For the purposes of determining whether the applicable conditions set forth in Section 7 hereof have been fulfilled, the Agent may assume the truth of the statements contained in certificates delivered pursuant to said Section.

(b) The Notice of Borrowing shall be irrevocable and binding on the Company and, in respect of any Borrowing comprised of Eurodollar Rate Loans specified in such Notice of Borrowing, the Company shall indemnify each Bank against any loss or expense incurred by such Bank as a result of any failure to fulfill on or before the date specified for such Borrowing the applicable conditions set forth in Section 7 hereof, including, without limitation, any amounts payable to the applicable Banks pursuant to Section 6.03 hereof (excluding loss of anticipated profits).

(c) Unless the Agent shall have received notice from a Bank prior to the date of any Borrowing pursuant to Section 5.01(a) hereof that such Bank will not make available to the Agent such Bank’s Proportionate Share of such Borrowing, the Agent may assume that such Bank has made such portion available to the Agent on the date of such Borrowing in accordance with Section 5.01(a) hereof and the Agent may, in reliance upon such assumption, make available to the Company on such date a corresponding amount. If such Bank’s Proportionate Share of such Borrowing is made available to the Agent on a date after the date of such Borrowing, such Bank shall pay to the Agent on demand an amount equal to the product of (i) the daily average Federal Funds Rate during such period as quoted by the Agent, times (ii) the amount of such Bank’s Proportionate Share of such Borrowing, times (iii) the number of days that elapse from and including the date of such Borrowing to the date on which such Bank’s ratable portion of such Borrowing shall have been made available to the Agent. A certificate of the Agent submitted to any Bank with respect to any amounts owing under this Section 5.01(c) shall be conclusive absent manifest error. If such Bank’s Proportionate Share of such Borrowing is not in fact made available to the Agent by such Bank within three (3) Business Days after the date of such Borrowing, the Company agrees to pay to the Agent, on demand, an amount equal to such Proportionate Share together with interest thereon, for each day from the date such amount was made available to the Company until the date such amount is repaid to the Agent, at the interest rate applicable at the time to the Loans comprising such Borrowing.

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

SECTION 5.02 Payments and Computations.

(a) The Company shall make each payment hereunder and under the Notes not later than 11:00 A.M. (Los Angeles, California time) on the day when due in Dollars to the Agent at its Principal Office in same day funds. The Agent will promptly thereafter (and in any event no later than 2:00 P.M., Los Angeles, California time, on the Business Day on which the Agent shall have received such payment in accordance with this Section 5.02(a)) cause to be distributed like funds relating to the payment of principal or interest (other than pursuant to Section 6 hereof) ratably to the Banks for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Bank to such Bank for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement.

(b) Subject to Section 15.04 hereof, the Company hereby authorizes each Bank, if and to the extent payment owed to such Bank is not made when due hereunder or under the Note or Notes held by such Bank, to charge (with notice thereof to the Company and the Agent) from time to time against any or all of the Company’s accounts with such Bank any amount so due. The rights of each Bank under this subsection (b) are in addition to (and not in limitation of) other rights and remedies (including, without limitation, rights of set-off) which such Bank may have.

(c) All computations of interest based on the Reference Rate shall be made by the Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Adjusted LIBOR Rate or the Federal Funds Rate shall be made by the Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such is payable. Each computation by the Agent (or, in the case of Section 6.01 hereof, by a Bank) of interest owing hereunder shall be conclusive and binding for all purposes absent manifest error.

(d) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees payable hereunder and under the other Financing Documents.

(e) Unless the Agent shall have received notice from the Company prior to the date on which any payment is due to the Banks hereunder that the Company will not make such payment in full, the Agent may assume that the Company has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due to such Bank. If and to the extent the Company shall not have so made such payment in full to the Agent, such Bank shall repay to the Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Agent, at the daily Federal Funds Rate as quoted by the Agent. A certificate of the Agent submitted to any Bank with respect to any amounts owing by such Bank under this Section 5.02(e) shall be conclusive absent manifest error.

SECTION 5.03 Sharing of Payments, Etc. Each Bank agrees that if it shall, by exercising any right of set-off or counterclaim or otherwise, receive payment of a proportion of the aggregate amount of principal and interest due with respect to any Note held by it (other than pursuant to Sections 6 and 14 hereof) which is greater than the proportion received by any other Bank in respect of the aggregate amount of principal and interest due with respect to any such Note held by such other Bank, the Bank receiving such proportionately greater payment shall purchase such participations in any such Notes held by the other Banks, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to such Notes held by the Banks shall be shared by the Banks in accordance with their Proportionate Shares; provided, that if all or any portion of such excess payment is thereafter recovered by or on behalf of the Company from such purchasing Bank, the purchase shall be rescinded and the purchase price restored to the extent of such recovery, together with each Bank’s pro rata share of any interest which such purchasing Bank is required to pay in respect thereof; and provided, further, that

nothing in this Section 5.03 shall impair the right of any Bank to exercise any right of set-off or counterclaim it may have and to apply the amount subject to such exercise to the payment of indebtedness of the Company other than its indebtedness under such Notes, except that such Bank shall not exercise such right except during the occurrence and continuance of an Event of Default. The Company agrees, to the fullest extent it may effectively do so under applicable law, that any holder of a participation in a Note, whether or not acquired pursuant to the foregoing arrangements, may exercise all its rights of payment (including its rights of set-off or counterclaim) and other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of the Company in the amount of such participation. Notwithstanding the foregoing, in no event shall any Bank receive any right of set-off or counterclaim against amounts due and owing to the Company under any Interest Rate Protection Agreement.

SECTION 5.04 Taxes.

(a) Any and all payments to the Agent and each Bank by the Company hereunder or under the Notes shall be made free and clear of and without deduction for any and all taxes, levies, imposts, deductions, charges or withholdings prescribed under the laws of the United States or a political subdivision thereof, and all liabilities with respect thereto, excluding in the case of each Bank and the Agent, (i) any taxes of such Bank or the Agent (including all income taxes) that would not have been imposed but for the existence of a connection between such Bank or the Agent and the jurisdiction imposing such taxes (other than a connection arising solely by reason of this Agreement, the Notes or the transactions contemplated herein) and (ii) franchise or capital or doing business taxes imposed on such Bank or the Agent by reason of a connection, created other than through this Agreement, the Notes or the transactions contemplated herein, between such Bank or the Agent and any jurisdiction where it is imposed (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If the Company shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note to any Bank or the Agent, (A) except as set forth in subsection (e) below, the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 5.04) such Bank or the Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (B) the Company shall make such deductions and (C) the Company shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) In addition, except as set forth in subsection (e) below, the Company agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under the Notes or from the execution or delivery or otherwise with respect to this Agreement, the Security Documents or the Notes (hereinafter referred to as “Other Taxes”).

(c) Except as set forth in subsection (e) below, the Company will indemnify each Bank and the Agent for the full amount of Taxes or Other Taxes (including, without limitation, any taxes, levies, imposts, deductions, charges or withholdings imposed by any jurisdiction on amounts payable under this Section 5.04) paid by such Bank or the Agent (as the case may be) or any liability (including penalties, interest and reasonable expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. This indemnification shall be made within ten (10) days from the date such Bank or the Agent (as the case may be) makes written demand therefor. A certificate setting forth and containing an explanation in reasonable detail of the manner in which such amount shall have been determined and the amount of such payment or liability prepared by a Bank or the Agent on its behalf shall accompany any written demand for amounts due under this Section and shall be conclusive absent manifest error.

(d) Within ten (10) days after the date of any payment of Taxes by the Company, the Company will furnish to the Agent, at its Principal Office, the original or a certified copy of a receipt evidencing payment thereof.

(e) If (i) the representations set forth in Section 5.05(a) hereof with respect to a Bank or the Agent shall prove to have been incorrect or (ii) a party fails to perform or observe its covenant set forth in Section 5.05(b) or 5.06 hereof, then the Company shall not be obligated to increase the sum payable in respect of Taxes as required by subsection (a) above, to make payments in respect of Other Taxes as required by subsection (b) above, or to indemnify such Bank or the Agent, as the case may be, as required by subsection (c) above to the extent that any increase in such Taxes or Other Taxes (as referred to in subsections (a), (b) and (c) above) proximately results from (A) any incorrect representations in Section 5.05(a) hereof or (B) any failure to perform or observe the covenants set forth in Section 5.05(b) or 5.06 hereof by such Bank or the Agent.

(f) Each Bank hereby agrees that it will designate a different Applicable Lending Office if such designation will avoid the need for, or, if unavoidable, reduce the amount of, Taxes or Other Taxes for which the Company is required to indemnify such Bank under this Section 5.04 and will not, in the sole opinion of such Bank, be disadvantageous to such Bank. Each Bank and the Agent hereby agrees to use reasonable efforts to contest the imposition of Taxes and Other Taxes (including penalties and interest) and, in the event of a determination that such Taxes or Other Taxes are not due, to return to the Company amounts paid pursuant to this Section 5.04. If any Taxes or Other Taxes for which the Agent or any Bank has received indemnification from the Company hereunder shall be finally determined to have been incorrectly or illegally asserted and are refunded to the Agent or such Bank, the Agent or such Bank, as the case may be, shall promptly forward to the Company any such refunded amount.

SECTION 5.05 Status of the Banks and the Agent.

(a) Each Bank and the Agent severally represents and warrants (solely for purposes of Section 5.04(e) hereof) that so long as such Bank or the Agent has any obligation under Section 3 hereof or is entitled to receive payments hereunder, either (i) it is acting for purposes hereof through a branch or office in the United States or (ii) it qualifies as a corporation, company, enterprise or resident of (A) the United States or (B) the country in which the branch or office it is acting through is located for purposes of an income tax convention between such country and the United States providing for a complete exemption from any withholding for or on account of Taxes with respect to all payments receivable by it hereunder, and, in case the foregoing clause (B) is applicable, that such Bank or the Agent is fully eligible for the benefit of that convention with respect to all payments receivable by it hereunder.

(b) If any Bank organized outside the United States is acting through a branch or office in the United States, so long as such Bank has any obligation under Section 3 or is entitled to receive payments hereunder, such Bank represents and warrants (solely for purposes of Section 5.04(e) hereof) that it shall conduct its business so that each payment received by it hereunder is effectively connected with the conduct by it of a trade or business in the United States.

SECTION 5.06 Tax Documentation.

(a) On or before the Closing Date, each Bank and the Agent shall, solely for the purposes of Section 5.04(e) hereof, deliver to the Company all requested forms and documents appropriate under the circumstances that are required to establish that payments hereunder by the Company are exempt from withholding for or on account of Taxes, all in form and substance satisfactory to the Agent and the Company. The forms to be delivered by any Bank or the Agent organized outside the United States shall include, if appropriate under the circumstances, and upon the request of the Company, Internal Revenue Service Form W-8ECI (if such Bank or the Agent is acting through a branch or office in the United States) or Form W-8BEN (if such Bank or the Agent is acting through a branch or office outside the United States).

(b) If any Bank is required at any time to execute any form or document (including, without limitation, Internal Revenue Service Form W-8BEN or Form W-8ECI) in order for payments to it hereunder to qualify for exemption from withholding for or on account of Taxes or for such withholding at a reduced rate, such Bank represents and warrants (solely for purposes of Section 5.04(e) hereof) that it shall, to the extent permitted by applicable Laws, execute the required form or document and deliver it to the appropriate party.

SECTION 6.

YIELD PROTECTION AND ILLEGALITY

SECTION 6.01 Additional Costs.

(a) The Company shall pay directly to any Bank from time to time such amounts as such Bank may determine to be necessary to compensate it for any costs which such Bank determines are attributable to its making or maintaining any Eurodollar Rate Loans, or its obligation to make any such Loans hereunder, or any reduction in any amount receivable by such Bank hereunder in respect of any of such Loans or such obligations (such increases in costs and reductions in amounts receivable being herein called “Additional Costs”), resulting from any Regulatory Change which: (i) imposes or modifies any reserve, special deposit, minimum capital, capital ratio or similar requirements, to the extent not included within the definition of “Reserve Requirement” in Section 1.01 hereof, relating to any extensions of credit or other assets of, or any deposits with or other liabilities of, such Bank (including any of such Loans or any deposits referred to in the definition of “LIBOR Rate” in Section 1.01 hereof), or any commitments of such Bank; or (ii) imposes any other condition affecting this Agreement or the Notes (or any of such extensions of credit or liabilities) or its Commitment (other than with respect to taxes (including any Taxes or Other Taxes), Section 5 hereof being the sole remedy of such Bank with respect thereto). Such Bank will notify the Company and the Agent of any event occurring after the date of this Agreement which will entitle such Bank to compensation pursuant to this Section 6.01(a) as promptly as practicable after it obtains knowledge thereof and shall determine as promptly as practicable after delivery of such notice whether it will determine to request such compensation, and such Bank will designate a different Applicable Lending Office for the Loans affected by such event if such designation will avoid the need for, or, if unavoidable, reduce the amount of, such compensation and will not, in the sole opinion of such Bank, be disadvantageous to such Bank, provided that such Bank shall have no obligation to so designate an Applicable Lending Office located in the United States. Each Bank will furnish the Company (with a copy to the Agent) with a certificate setting forth the basis and amount of each request by such Bank for compensation under this Section 6.01(a).

(b) Without limiting the effect of the provisions of Section 6.01(a) hereof, in the event that, by reason of any Regulatory Change, any Bank either (i) incurs Additional Costs based on or measured by the excess above a specified level of the amount of a category of deposits or other liabilities of such Bank which includes deposits by reference to which the interest rate on Eurodollar Rate Loans is determined as provided in this Agreement or a category of extensions of credit or other assets of such Bank which includes Eurodollar Rate Loans or (ii) becomes subject to restrictions on the amount of such a category of liabilities or assets which it may hold, then, if such Bank so elects by notice to the Agent and the Company, the obligation of such Bank to make additional Loans of such Type hereunder shall be suspended until such Regulatory Change ceases to be in effect.

(c) Without limiting the effect of the foregoing provisions of this Section 6.01 (but without duplication), the Company shall pay directly to each Bank from time to time on request such amounts as such Bank may determine to be necessary to compensate such Bank for any costs which it determines are attributable to the maintenance by such Bank or any of its affiliates, as a result of a Regulatory Change, of capital in respect of its maintaining Loans hereunder or its obligation to make Loans hereunder (such compensation to include, without limitation, an amount equal to any reduction of the rate of return on assets or equity of such Bank to a level below that which such Bank could have achieved but for such law, regulation, interpretation, directive or request). Each Bank will notify the Company that it is entitled to compensation pursuant to this Section 6.01(c) as promptly as practicable after it obtains knowledge thereof and shall determine as promptly as practicable after delivery of such notice whether it will determine to request such compensation, and such Bank will designate a different Applicable Lending Office for the Loans affected by such event if such designation will avoid the need for, or, if unavoidable, reduce the amount of, such compensation and will not, in the sole opinion of such Bank, be disadvantageous to such Bank, provided that such Bank shall have no obligation to so designate an Applicable Lending Office located in the United States. Each Bank will furnish the Company (with a copy to the Agent) with a certificate setting forth the basis and amount of each request by such Bank for compensation under this Section 6.01(c).

(d) Determinations and allocations by any Bank for purposes of this Section 6.01 of the effect of any Regulatory Change on its costs of making or maintaining Loans or maintaining its obligations to make Loans or on amounts receivable by it in respect of its Loans or such obligations, and of the additional amounts required to compensate such Bank in respect of any Additional Costs, shall be conclusive, provided that such determinations and allocations are made on a reasonable basis.

(e) If any Bank requests compensation for Additional Costs from the Company under Section 6.01(a) hereof, the Company may either (i) prepay in full all Eurodollar Rate Loans of all Banks then outstanding, together with interest accrued thereon, in accordance with Section 4.02 hereof, or (ii) Convert all Eurodollar Rate Loans of all Banks in accordance with Section 3.03 hereof, and in each case the Company shall also pay such Additional Costs to such Bank in accordance with this Section 6.01 on the date of such prepayment or Conversion, as the case may be.

(f) Failure or delay on the part of any Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Bank’s right to demand such compensation; provided that the Company shall not be required to compensate a Bank pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Bank notifies the Company of the Regulatory Change giving rise to such increased costs or reductions and of such Bank’s intention to claim compensation therefor; provided further that, if the Regulatory Change giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

SECTION 6.02 Illegality. Notwithstanding any other provision of this Agreement, if, subsequent to the date hereof, the enactment of or any change in or in the interpretation of any law or regulation shall make it unlawful, or any central bank or other Governmental Authority shall assert that it is unlawful, for any Bank or its Applicable Lending Office to perform its obligations hereunder to make Eurodollar Rate Loans or to continue to fund or maintain Eurodollar Rate Loans hereunder, then, on notice thereof and demand therefor by such Bank to the Company through the Agent, (a) the obligation of such Bank to make Eurodollar Rate Loans and to Convert Loans into Eurodollar Rate Loans shall terminate and (b) the Company shall forthwith prepay in full all Eurodollar Rate Loans of such Bank then outstanding (but only to the extent that prepayment prior to the last day of the applicable Interest Period(s) therefor is required by law or by any central bank or other Governmental Authority), together with interest accrued thereon, and compensation with respect thereto pursuant to Section 6.03 hereof, unless the Company, within five (5) Business Days of such notice and demand, Converts all Eurodollar Rate Loans of all Banks then outstanding into Alternate Base Rate Loans in accordance with Section 3.03 hereof.

SECTION 6.03 Compensation. The Company shall compensate each Bank, upon written request by such Bank (which request shall set forth the basis for requesting such amounts) to the Agent and the Company, for all reasonable losses and expenses, including, without limitation, any interest paid by such Bank to lenders of funds borrowed by it or deposited with it to make or maintain its Eurodollar Rate Loans, which such Bank may sustain, to the extent not otherwise compensated for hereunder and not mitigated by the reemployment of such funds: (a) if for any reason (other than a default by such Bank) a Borrowing or Conversion of any Loan does not occur on a date specified therefor in a Notice of Borrowing given pursuant to Section 5.01 hereof or in a notice of Conversion given pursuant to Section 3.03 hereof, (b) if any prepayment, repayment or Conversion of its Eurodollar Rate Loans occurs on a date which is not the expiration date of the relevant Interest Period or (c) if any prepayment of its Eurodollar Rate Loans is not made on any date specified in a notice of prepayment given by the Company. Without prejudice to the foregoing, the Company shall indemnify each Bank against any loss or expense which such Bank (or its Applicable Lending Office or affiliate) may sustain or incur as a consequence of the default by the Company in payment of principal of or interest on any Eurodollar Rate Loan, or any part thereof, or of any amount due under this Agreement, including, but not limited to, any premium or penalty incurred by such Bank (or its Applicable Lending Office or affiliate) in respect of funds borrowed by it or deposited with it for the purpose of making or maintaining such Eurodollar Rate Loan, as determined by such Bank in good faith in the exercise of its sole discretion. A certificate as to any such loss or expense (specifying the basis of such loss or expense) shall be promptly submitted by such Bank to the Company (with a copy to the Agent) and shall, in the absence of manifest error, be conclusive and binding as to the amount thereof.

SECTION 8.

AFFIRMATIVE COVENANTS

So long as any Loan or any other Obligations payable hereunder or under any Note shall remain unpaid or any Bank shall have any Commitment:

SECTION 8.01 Payment of Obligations. The Company will pay, discharge or otherwise satisfy at or before maturity or before they become delinquent or in default (after any applicable period of grace), as the case may be, all of its Debt and other obligations that, if not paid, could reasonably be expected to result in a Material Adverse Effect except when (a) the validity or amount thereof is being contested in good faith by appropriate proceedings, (b) the Company has set aside on its books adequate reserves with respect thereto to the extent required by and otherwise in accordance with GAAP and (c) the failure to make payment pending such contest could not reasonably be expected to result in a Material Adverse Effect.

SECTION 8.02 Maintenance of Existence. The Company will do or cause to be done all things necessary to preserve and keep in full force and effect its legal existence. The Company will become and remain registered to conduct business in each jurisdiction where the nature of its business or ownership of its Property may require such registration.

SECTION 8.03 Preservation of Property. The Company will at all times maintain, preserve and protect all trade names and keep all the remainder of its Properties that are necessary in the conduct of its business whether owned in fee or otherwise, or leased, in good repair and operating condition, normal wear and tear excepted. The Company will comply with all material leases to which it is a party (including, without limitation, the Ground Lease) or under which it occupies property so as to prevent any material loss or forfeiture thereunder. The Company shall, at its expense (or shall cause UNS Electric, at UNS Electric’s expense, to), (i) keep the Project in good working order and condition and make (or cause to be made) all necessary repairs, replacements, restorations, improvements and renewals with respect thereto and additions and betterments thereto, normal wear and tear excepted, and (ii) operate the Plant in compliance with all Laws affecting the Project and in accordance with Prudent Industry Practices, except where the failure to so operate the Plant would not reasonably be expected to result in a Material Adverse Effect.

SECTION 8.04 Insurance.

(c) If the Company has assumed the defense of any action, suit or proceeding pursuant to subsection (b) of this Section 11, the Company shall promptly report to such Indemnified Person on the status of such action, suit or proceeding as material developments shall occur and from time to time as requested by such Indemnified Person.

(e) To the extent that the Company fails to pay any amount required to be paid by it to the Agent under subsection (a) of this Section or under Section 12 hereof, each Bank severally agrees to pay to the Agent such Bank’s Proportionate Share (determined as of the time that the applicable unreimbursed indemnity payment or expense is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Agent in its capacity as such.

(f) To the extent permitted by applicable Laws, the Company shall not assert, and hereby waives, any claim against any Indemnified Person, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Transaction Document or any agreement or instrument contemplated hereby, any Loan or the use of the proceeds thereof.

(g) All amounts due under this Section shall be payable promptly after delivery to the Company of a reasonably detailed statement therefor.

SECTION 13.

THE AGENT AND RELATIONS AMONG BANKS

SECTION 13.01 Appointment of Agent, Powers and Immunities. Each Bank hereby irrevocably appoints and authorizes the Agent to act as its agent hereunder and under the other Transaction Documents with such powers as are expressly delegated to the Agent by the terms of this Agreement and the other Transaction Documents, together with such other powers as are reasonably incidental thereto. The Agent shall not have any duties or responsibilities except those expressly set forth in this Agreement or in any other Transaction Document, or be a trustee for any Bank. Notwithstanding anything to the contrary contained herein, the Agent shall not be required to take any action which is contrary to this Agreement or any other Transaction Document or applicable Laws. Neither the Agent nor any Bank nor any of their respective affiliates shall be responsible to any other Bank for any recitals, statements, representations or warranties made by any Loan Party contained in this Agreement or any other Transaction Document or in any certificate or other document referred to or provided for in, or received by any Bank under, this Agreement or any other Transaction Document, for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement, any other Transaction Document or any other document referred to or provided for herein or therein or for any failure by any Loan Party to perform its obligations hereunder or thereunder. The Agent may employ agents and attorneys-in-fact and shall not be responsible for the negligence or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. Neither the Agent nor any of its directors, officers, employees or agents shall be responsible for any action taken or omitted to be taken by it or them hereunder or under any other Transaction Document or in connection herewith or therewith, except for its or their own gross negligence or willful misconduct as determined by the final judgment of a court of competent jurisdiction. Except as otherwise provided under this Agreement, the Agent shall take such actions with respect to the Security Documents as shall be directed by the Majority Banks, subject to the requirements that the Security Documents shall continue at all times to equally and ratably secure the Secured Parties.

SECTION 13.02 Reliance by Agent. The Agent shall be entitled to rely upon any certificate, notice or other document (including any cable, telegram, telecopy, telex or electronic transmission) believed by it to be genuine and correct and to have been signed or sent by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by the Agent. As to any matters not expressly provided for by this Agreement or any other Transaction Document, the Agent shall not be required to take any action or exercise any discretion, but shall be required to act or to refrain from acting upon instructions of the Majority Banks and shall in all cases be fully protected in acting, or in refraining from acting, hereunder or under any other Transaction Document in accordance with the instructions of the Majority Banks, and such instructions of the Majority Banks and any action taken or failure to act pursuant thereto shall be binding on all of the Banks.

SECTION 13.03 Defaults. The Agent shall not be deemed to have knowledge or notice of the occurrence of a Default unless the Agent has received notice from a Bank or the Company referring to this Agreement, describing such Default and stating that such notice is a “Notice of Default”. In the event that the Agent receives such a notice of the occurrence of a Default the Agent shall give notice thereof to the Banks. The Agent shall take such action with respect to such Default as shall be reasonably directed by the Majority Banks; provided that, unless and until the Agent shall have received such directions, the Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interest of the Banks.

SECTION 13.04 Rights as a Bank. With respect to its commitment to make Loans, the Agent shall have the same rights and powers hereunder as any Bank and may exercise the same as though it was not acting as the Agent, and the terms “Bank” or “Banks” shall, unless the context otherwise indicates, include the Agent in its individual capacity. The Agent and its affiliates may (without having to account therefor to any Bank) accept deposits from, extend credit (on a secured or unsecured basis) to and generally engage in any kind of banking, trust or other business with the Company or any of its affiliates, as if it were not acting as the Agent.

SECTION 13.05 Indemnification. Without limiting the obligations of the Company under Sections 10, 11 and 12 hereof, each Bank agrees to indemnify the Agent, ratably in accordance with its Proportionate Share, for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may at any time (including, without limitation, at any time following the payment of principal of and/or interest on the Loans) be imposed on, incurred by or asserted against the Agent in any way relating to or arising out of this Agreement, any other Transaction Document or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby (including the costs and expenses which the Company is obligated to pay under Sections 11 and 12 hereof) or the enforcement of any of the terms hereof or thereof or of any such other documents, provided that no Bank shall be liable for any of the foregoing to the extent they arise from the Agent’s gross negligence or willful misconduct. The Agent shall be fully justified in refusing to take or to continue to take any action hereunder or under any other Transaction Document unless it shall first be indemnified to its satisfaction by the Banks against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action.

SECTION 13.06 Documents. The Agent will forward to each Bank, promptly after the Agent’s receipt thereof, a copy of each document furnished to the Agent for such Bank hereunder and of each opinion furnished to the Agent pursuant to Section 7.

SECTION 13.07 Non-Reliance on Agent and Other Banks. Each Bank represents that it has, independently and without reliance on the Agent or any other Bank, and based on such documents and information as it has deemed appropriate, made its own appraisal of the financial condition and affairs of the Loan Parties and decision to enter into this Agreement and agrees that it will, independently and without reliance upon the Agent or any other Bank, and based on such documents and information as it shall deem appropriate at the time, continue to make its own appraisals and decisions in taking or not taking action under this Agreement and the other Financing Documents. Neither the Agent nor any Bank shall be required to keep informed as to the performance or observance by any Loan Party under this Agreement, any other Transaction Document or any other document referred to or provided for herein or therein or to make inquiry of, or to inspect the properties or books of, any Loan Party. Except for notices, reports and other documents and information expressly required to be furnished to the Banks by the Agent hereunder, neither the Agent nor any Bank shall have any duty or responsibility to provide any Bank with any credit or other information concerning any Loan Party or any Affiliate thereof, which may come into the possession of the Agent or such Bank or any of its or their affiliates.

SECTION 13.08 Resignation or Removal of Agent. Subject to the appointment and acceptance of a successor Agent as provided below, the Agent may resign at any time by giving notice thereof to the Banks and the Company, and the Agent may be removed at any time with or without cause by the Majority Banks. Upon any such resignation or removal, the Majority Banks shall have the right to appoint a successor Agent, which Agent shall be reasonably acceptable to the Company. If no successor Agent shall have been appointed by the Majority Banks and shall have accepted such appointment within 30 days after the retiring Agent’s giving of notice of resignation or the Majority Banks’ removal of the retiring Agent, then the retiring Agent may, on behalf of the Banks, appoint a successor Agent, which shall be a bank with an office (or an affiliate with an office) in Los Angeles, California, or New York, New York, having a combined capital and surplus of not less than $500,000,000 and which shall be reasonably acceptable to the Company. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. After any retiring Agent’s resignation or removal hereunder as Agent, the provisions of this Section 13 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Agent.

SECTION 13.09 Authorization. The Agent is hereby authorized by the Banks to execute, deliver and perform each of the Transaction Documents to which the Agent is or is intended to be a party and each Bank agrees to be bound by all of the agreements of the Agent contained in the Transaction Documents.

SECTION 14.

PARTICIPATIONS AND ASSIGNMENTS BY THE BANKS

SECTION 14.01 Participation and Assignment. Any Bank may assign any or all of its rights or obligations hereunder to any Person (other than the Company and its Affiliates) pursuant to an assignment and assumption agreement substantially in the form of Exhibit H hereto, provided that the assignee thereof is reasonably acceptable to the Company (provided, that the consent of the Company to an assignee shall not be required upon the occurrence and during the continuance of an Event of Default or if the assignee is an existing Bank). Nothing herein provided shall prevent any Bank from selling at any time a participation in any of its Loans, any fees payable to it hereunder or any other rights hereunder (the purchaser of any such participation being hereinafter sometimes referred to as a “Participant”); provided that: (a) no such sale or participation shall alter such Bank’s obligations hereunder, (b) such Bank shall remain solely responsible to the other parties hereto for the performance of such Bank’s obligations hereunder and (c) any agreement pursuant to which any Bank may grant any such participation shall provide that such Bank shall retain the sole right and responsibility to exercise the rights of such Bank, and enforce the obligations of the Company relating to such Bank’s Commitment, the Loans, the fees payable hereunder and any other right of such Bank (including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement or any other Transaction Document and the right to take action to have the Loans declared due and payable), except that such Bank may agree with the Participant that such Bank will not, without the consent of such Participant, agree to (i) increase or extend the term, or extend the time or waive any requirement for the reduction or termination, of such Bank’s Commitment hereunder in which such Participant has a participation interest, (ii) extend the date fixed for the payment of principal of or interest on any Loan or any portion of any fee under this Agreement in each case payable to such Participant, (iii) reduce the amount of any such payment of principal, or (iv) reduce the rate at which interest or any fee under this Agreement in which such Bank has sold an interest is payable to such Participant to a level below the rate at which such Participant is entitled to receive such interest or fee under its agreement with such Bank. No Participant shall have any rights under this Agreement or in respect of a Bank’s Commitment, Loans, fees payable to it hereunder or any other rights hereunder other than to receive payments in respect of such Participant’s participation from such Bank.

SECTION 15.

MISCELLANEOUS

SECTION 15.01 No Waiver, Remedies Cumulative. No failure to exercise and no delay in exercising on the part of the Agent or any Bank of any right, power or privilege hereunder or under any other Financing Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or privilege preclude any other or further exercise thereof, or the exercise of any other right, power or privilege.

This Agreement shall be binding upon and inure to the benefit of the Company, the Agent and each Bank and their respective successors and assigns, except that the Company may not assign or otherwise transfer all or any part of its rights or obligations hereunder without the prior written consent of each Bank.

SECTION 15.04 Right of Set-off.

(a) Upon the occurrence and during the continuance of any Event of Default, each Bank is, subject to the provisions of Sections 5.03 and 13 hereof, hereby authorized at any time and from time to time, without notice to the Company (any such notice being expressly waived by the Company) and to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held, and other indebtedness at any time owing, by such Bank in any of its offices to or for the credit or the account of the Company against any and all of the respective obligations of the Company now or hereafter existing under the Financing Documents, irrespective of whether or not such Bank or any other Bank shall have made any demand hereunder and although such obligations may be contingent or unmatured and such deposits or indebtedness may be unmatured.

(b) Each Bank shall promptly notify the Company after any such set-off and application, provided that the failure to give such notice shall not affect the validity of such set-off and application. Rights of the Banks under this Section 15.04 are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the Banks may have.
