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 Administrative Agent. All payments by the Borrower to the Lenders under this Section 3.02 shall be made through the Administrative Agent.

SECTION 3.03. Lending Office. Loans of each Type shall be made and maintained at each Lender’s Applicable Lending Office for such Type of Loan.

SECTION 3.04. Pro Rata Treatment. Except as otherwise provided herein, each Borrowing of Loans shall be made among the Lenders pro rata according to there respective Proportionate Shares, and payment of principal of and interest on the Loans and any applicable Prepayment Premium shall be made pro rata among the Lenders according to the respective unpaid principal amounts of the Loans held by the Lenders.

SECTION 3.05. Interest Rates. The Borrower shall pay interest on the unpaid principal amount of each Loan made by each Lender from the date of such Loan until such principal amount shall be paid in full, at one of the following rates per annum:

(a) ABR Loans. If such Loan is an ABR 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 Borrower 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 Borrower hereunder or under any Promissory 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 3.06. 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 Administrative Agent.

SECTION 3.07. Maximum Interest. Notwithstanding anything to the contrary contained in this Agreement or in any other Loan Document, the interest paid or agreed to be paid under this Agreement and the Promissory 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 Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal amount of the Loans owing to such Lender or, if it exceeds such unpaid principal amount, refunded to the Borrower. In determining whether the interest contracted for, charged, or received by the Administrative Agent or a Lender 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 3.08. Promissory Notes. Any Lender may request that Loans made by it hereunder be evidenced by a Promissory Note. In such event, the Borrower shall prepare, execute and deliver to such Lender a Promissory Note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent. Thereafter, the Loans evidenced by such Promissory Note and interest thereon shall at all times (including after assignment pursuant to Section 12.07) be represented by one or more Promissory Notes in such form payable to the order of the payee named therein (or, if such Promissory Note is a registered note, to such payee and its registered assigns).

SECTION 3.09. Termination by Borrower. The Borrower may terminate this Agreement upon payment in full of all amounts then owing to the Lenders and the Administrative Agent under this Agreement and the other Loan Documents and all other Obligations (including, without limitation, any applicable Prepayment Premium), subject to Section 3.02(a); provided, however, that no such termination shall be effective until all such amounts have been paid in full and, prior to the occurrence of the Guaranty Termination Date, all outstanding Interest Rate Protection Agreements have expired or been terminated.

SECTION 4.01. Making the Loans.

(a) The initial Borrowing shall be made upon notice, given not later than 11:00 A.M. (Los Angeles, California time) one (1) Business Day (to the extent that the initial Borrowing will consist of ABR Loans) and three (3) Business Days (to the extent that the initial Borrowing will consist of Eurodollar Rate Loans) prior to the Closing Date, by the Borrower to the Administrative Agent, which shall give to each Lender prompt notice thereof and of each other notice received from the Borrower hereunder. The notice of such Borrowing (the “Notice of Borrowing”) shall be in writing, substantially in the form of Exhibit A-1 hereto, and specifying therein (i) the requested date of such Borrowing, (ii) the requested Type and amount of each Loan comprising such Borrowing, (iii) the requested aggregate amount of such Borrowing, and (iv) in the case of a Borrowing comprised of Eurodollar Rate Loans, the initial Interest Period for each such Loan. In the case of a proposed Borrowing comprised of Eurodollar Rate Loans, the Administrative Agent shall promptly notify each Lender of the applicable interest rate pursuant to Section 3.05. Each Lender shall, before 11:00 A.M. (Los Angeles, California time) on the date of such Borrowing, make available for the account of its Applicable Lending Office to the Administrative Agent at its Principal Office, in same day funds, such Lender’s Proportionate Share of such Borrowing. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article VI, the Administrative Agent will make such funds available to the Borrower by promptly crediting the amounts so received in like funds to an account of the Borrower designated by the Borrower in the Notice of Borrowing. For the purposes of determining whether the applicable conditions set forth in Article VI have been fulfilled, the Administrative Agent may assume the truth of the statements contained in certificates delivered pursuant to said Section.

(b) Each Notice of Borrowing and Notice of Conversion shall be irrevocable and binding on the Borrower. In the case of any Borrowing which the related Notice of Borrowing or Notice of Conversion specifies is to be comprised of Eurodollar Rate Loans, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure by the Borrower to fulfill, on or before the date specified in such Notice of Borrowing or Notice of Conversion for such Borrowing, the applicable conditions (if any) set forth in Article II (other than failure pursuant to the provisions of Section 2.02(c)), this Article IV or Article VI, including, without limitation, any amounts payable to the applicable Lenders pursuant to Section 5.03 (excluding loss of anticipated profits).

(c) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any Borrowing pursuant to Section 4.01(a) that such Lender will not make available to the Administrative Agent such Lender’s Proportionate Share of such Borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the date of such Borrowing in accordance with Section 4.01(a) and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If such Lender’s Proportionate Share of such Borrowing is made available to the Administrative Agent on a date after the date of such Borrowing, such Lender shall pay to the Administrative Agent on demand an amount equal to the product of (i) the daily average Federal Funds Effective Rate during such period as quoted by the Administrative Agent, times (ii) the amount of such Lender’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 Lender’s ratable portion of such Borrowing shall have been made available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this Section 4.01(c) shall be conclusive absent manifest error. If such Lender’s Proportionate Share of such Borrowing is not in fact made available to the Administrative Agent by such Lender within three (3) Business Days after the date of such Borrowing, the Borrower agrees to pay to the Administrative 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 Borrower until the date such amount is repaid to the Administrative Agent, at the interest rate applicable at the time to the Loans comprising such Borrowing.

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

SECTION 4.02. Payments and Computations.

(a) The Borrower shall make each payment hereunder and under the other Loan Documents not later than 11:00 A.M. (Los Angeles, California time) on the day when due in Dollars to the Administrative Agent at its Principal Office in same day funds. The Administrative 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 Administrative Agent shall have received such payment in accordance with this Section 4.02(a)) cause to be distributed like funds relating to the payment of principal or interest (other than pursuant to Article V) ratably to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender 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 12.05, the Borrower hereby authorizes each Lender, if and to the extent payment owed to such Lender is not made when due hereunder or under any other Loan Document, to charge (with notice thereof to the Borrower and the Administrative Agent) from time to time against any or all of the Borrower’s accounts with such Lender any amount so due. The rights of each Lender 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 Lender may have.

(c) All computations of interest based on the Reference Rate shall be made by the Administrative 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 Effective Rate shall be made by the Administrative 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 Administrative Agent (or, in the case of Section 5.01, by a Lender) of interest owing hereunder shall be conclusive and binding for all purposes absent manifest error.

(d) Whenever any payment hereunder or under any other Loan Document 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 payable hereunder and under the other Loan Documents; provided, however, that if such extension would cause payment of interest on or principal of Eurodollar Rate Loans to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(e) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date, and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due to such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Administrative Agent, such Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the daily Federal Funds Effective Rate as quoted by the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing by such Lender under this Section 4.02(e) shall be conclusive absent manifest error.

SECTION 4.03. Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Loans owing to it (other than pursuant to Article V or Section 12.07) in excess of its ratable share of payments obtained by all the Lenders on account of the Loans of such Lenders, such Lender shall forthwith purchase from the other Lenders such participation in the Loans owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 4.03 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. Notwithstanding the foregoing, if any Lender shall obtain any such excess payment involuntarily, such Lender may, in lieu of purchasing participations from the other Lenders in accordance with this Section 4.03, on the date of receipt of such excess payment, return such excess payment to the Administrative Agent for distribution in accordance with Section 4.02.

SECTION 4.04. Taxes.

(a) Any and all payments to the Administrative Agent and each Lender by the Borrower hereunder or under the other Loan Documents 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 Lender and the Administrative Agent, (i) any taxes of such Lender or the Administrative Agent (including all income taxes) that would not have been imposed but for the existence of a connection between such Lender or the Administrative Agent and the jurisdiction imposing such taxes (other than a connection arising solely by reason of this Agreement, the other Loan Documents or the transactions contemplated herein) and (ii) franchise or capital or doing business taxes imposed on such Lender or the Administrative Agent by reason of a connection, created other than through this Agreement, the other Loan Documents or the transactions contemplated herein, between such Lender or the Administrative 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 Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any other Loan Document to any Lender or the Administrative 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 4.04) such Lender or the Administrative Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (B) the Borrower shall make such deductions and (C) the Borrower 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 Borrower 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 other Loan Documents or from the execution or delivery or otherwise with respect to this Agreement or the other Loan Documents (hereinafter referred to as “Other Taxes”).

(c) Except as set forth in subsection (e) below, the Borrower will indemnify each Lender and the Administrative 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 4.04) paid by such Lender or the Administrative 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 Lender or the Administrative 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 Lender or the Administrative 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 Borrower, the Borrower will furnish to the Administrative 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 4.05(a) with respect to a Lender or the Administrative Agent shall prove to have been incorrect or (ii) a party fails to perform or observe its covenant set forth in Section 4.05(b) or Section 4.06, then the Borrower 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 Lender or the Administrative 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 4.05(a) or (B) any failure to perform or observe the covenants set forth in Section 4.05(b) or Section 4.06 by such Lender or the Administrative Agent.

(f) Each Lender 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 Borrower is required to indemnify such Lender under this Section 4.04 and will not, in the sole opinion of such Lender, be disadvantageous to such Lender. Each Lender and the Administrative 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 Borrower amounts paid pursuant to this Section 4.04. If any Taxes or Other Taxes for which the Administrative Agent or any Lender has received indemnification from the Borrower hereunder shall be finally determined to have been incorrectly or illegally asserted and are refunded to the Administrative Agent or such Lender, the Administrative Agent or such Lender, as the case may be, shall promptly forward to the Borrower any such refunded amount.

SECTION 4.05. Status of the Lenders and the Administrative Agent.

(a) Each Lender and the Administrative Agent severally represents and warrants (solely for purposes of Section 4.04(e)) that so long as such Lender or the Administrative Agent has any obligation under Article II 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 Lender or the Administrative Agent is fully eligible for the benefit of that convention with respect to all payments receivable by it hereunder.

(b) If any Lender organized outside the United States is acting through a branch or office in the United States, so long as such Lender has any obligation under Article II or is entitled to receive payments hereunder, such Lender represents and warrants (solely for purposes of Section 4.04(e)) 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 4.06. Tax Documentation.

(a) On or before the Closing Date, each Lender and the Administrative Agent shall, solely for the purposes of Section 4.04(e), deliver to the Borrower all requested forms and documents appropriate under the circumstances that are required to establish that payments hereunder by the Borrower are exempt from withholding for or on account of Taxes, all in form and substance satisfactory to the Administrative Agent and the Borrower. The forms to be delivered by any Lender or the Administrative Agent organized outside the United States shall include, if appropriate under the circumstances, and upon the request of the Borrower, Internal Revenue Service Form W-8ECI (if such Lender or the Administrative Agent is acting through a branch or office in the United States) or Form W-8BEN (if such Lender or the Administrative Agent is acting through a branch or office outside the United States).

(b) If any Lender 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 Lender represents and warrants (solely for purposes of Section 4.04(e)) that it shall, to the extent permitted by applicable Laws, execute the required form or document and deliver it to the appropriate party.

ARTICLE V
YIELD PROTECTION AND ILLEGALITY

SECTION 5.01. Additional Costs.

(a) The Borrower shall pay directly to any Lender from time to time such amounts as such Lender may determine to be necessary to compensate it for any costs which such Lender 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 Lender 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, relating to any extensions of credit or other assets of, or any deposits with or other liabilities of, such Lender (including any of such Loans or any deposits referred to in the definition of “LIBOR Rate” in Section 1.01), or any commitments of such Lender; or (ii) imposes any other

condition affecting this Agreement or the Promissory 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 4.04 being the sole remedy of such Lender with respect thereto). Such Lender will notify the Borrower and the Administrative Agent of any event occurring after the date of this Agreement which will entitle such Lender to compensation pursuant to this Section 5.01(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 Lender 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 Lender, be disadvantageous to such Lender, provided that such Lender shall have no obligation to so designate an Applicable Lending Office located in the United States. Each Lender will furnish the Borrower (with a copy to the Administrative Agent) with a certificate setting forth the basis and amount of each request by such Lender for compensation under this Section 5.01(a).

(b) Without limiting the effect of the provisions of Section 5.01(a), in the event that, by reason of any Regulatory Change, any Lender 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 Lender 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 Lender 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 Lender so elects by notice to the Administrative Agent and the Borrower, the obligation of such Lender 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 5.01 (but without duplication), the Borrower shall pay directly to each Lender from time to time on request such amounts as such Lender may determine to be necessary to compensate such Lender for any costs which it determines are attributable to the maintenance by such Lender 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 Lender to a level below that which such Lender could have achieved but for such law, regulation, interpretation, directive or request). Each Lender will notify the Borrower that it is entitled to compensation pursuant to this Section 5.01(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 Lender 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 Lender, be disadvantageous to such Lender, provided that such Lender shall have no obligation to so designate an Applicable Lending Office located in the United States. Each Lender will furnish the Borrower (with a copy to the Administrative Agent) with a certificate setting forth the basis and amount of each request by such Lender for compensation under this Section 5.01(c).

(d) Determinations and allocations by any Lender for purposes of this Section 5.01 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 Lender in respect of any Additional Costs, shall be conclusive, provided that such determinations and allocations are made on a reasonable basis.

(e) If any Lender requests compensation for Additional Costs from the Borrower under Section 5.01(a), the Borrower may either (i) prepay in full all Eurodollar Rate Loans of all Lenders then outstanding, together with interest accrued thereon, in accordance with Section 3.02, or (ii) Convert all Eurodollar Rate Loans of all Lenders in accordance with Section 2.03, and in each case the Borrower shall also pay such Additional Costs to such Lender in accordance with this Section 5.01 on the date of such prepayment or Conversion, as the case may be.

(f) Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender notifies the Borrower of the Regulatory Change giving rise to such increased costs or reductions and of such Lender’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 5.02. 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 Lender 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 Lender to the Borrower through the Administrative Agent, (a) the obligation of such Lender to make Eurodollar Rate Loans and to Convert Loans into Eurodollar Rate Loans shall terminate and (b) the Borrower shall forthwith prepay in full all Eurodollar Rate Loans of such Lender 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 5.03, unless the Borrower, within five (5) Business Days of such notice and demand, Converts all Eurodollar Rate Loans of all Lenders then outstanding into ABR Loans in accordance with Section 2.03.

SECTION 5.03. Compensation. The Borrower shall compensate each Lender, upon written request by such Lender (which request shall set forth the basis for requesting such amounts) to the Administrative Agent and the Borrower, for all reasonable losses and expenses, including, without limitation, any interest paid by such Lender to lenders of funds borrowed by it or deposited with it to make or maintain its Eurodollar Rate Loans, which such Lender 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 Lender) a Borrowing or Conversion of any Loan does not occur on a date specified therefor in a Notice of Borrowing given pursuant to Section 4.01 or in a Notice of Conversion given pursuant to Section 2.03, (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 Borrower. Without prejudice to the foregoing, the Borrower

shall indemnify each Lender against any loss or expense which such Lender (or its Applicable Lending Office or affiliate) may sustain or incur as a consequence of the default by the Borrower 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 Lender (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 Lender 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 Lender to the Borrower (with a copy to the Administrative Agent) and shall, in the absence of manifest error, be conclusive and binding as to the amount thereof.

(b) Authorization, Execution and Delivery. Each Loan Document to which such Obligor is a party has been duly authorized by all necessary corporate action on the part of such Obligor, and upon execution and delivery thereof each such Loan Document will constitute a legal, valid and binding obligation of such Obligor enforceable against such Obligor in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

(b) Any Lender serving as Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and such Lender and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Obligors or any of their Subsidiaries or other Affiliates thereof as if it were not the Administrative Agent hereunder.

(c) The Administrative Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (i) the Administrative Agent (in such capacity) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or an Event of Default has occurred and is continuing, (ii) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by the Loan Documents that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.01), and (iii) except as expressly set forth in the Loan Documents, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Obligors or any of their Subsidiaries or Affiliates that is communicated to or obtained by the Lender serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section

12.01) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until written notice thereof is given to the Administrative Agent by an Obligor or a Lender (in which case the Administrative Agent shall promptly give a copy of such written notice to the Lenders).

After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 12.04 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

(g) Each Lender acknowledges that it has independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

SECTION 10.02. Indemnification. The Lenders agree to indemnify the Administrative Agent (to the extent not reimbursed by the Obligors), ratably in accordance with their respective Proportionate Shares, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of this Agreement or any other Loan Document or any action taken or omitted by the Administrative Agent under this Agreement or any other Loan Document, provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s gross negligence or willful misconduct, as determined by the final and nonappealable judgment of a court of competent jurisdiction. Without limitation of the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, syndication, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement or any other Loan Document to the extent that the Administrative Agent is entitled to reimbursement for such expenses pursuant to Section 12.04 but is not reimbursed for such expenses by the Obligors.

ARTICLE XI
GUARANTY

SECTION 11.01. The Guaranty. The Guarantor hereby guarantees to each Lender, the Administrative Agent and their respective successors and assigns the prompt payment in full of all unpaid principal of and interest on (including, without limitation, interest accruing after the maturity of the Loans and interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, relating to the Borrower, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding) the Loans and all other Obligations of the Borrower to the Administrative Agent or any Lender, whether direct or indirect, absolute or contingent, due or to become due, or now existing or hereafter incurred, which may arise under, out of, or in connection with, this Agreement, any other Loan Document or any other document made, delivered or given in connection herewith or therewith, whether on account of principal, interest, fees, indemnities, Prepayment

Premium, costs, expenses (including, without limitation, all reasonable fees, charges and disbursements of counsel to the Administrative Agent or any Lender that are required to be paid by the Borrower pursuant hereto) or otherwise, in each case strictly in accordance with the express terms hereof (such obligations of the Borrower being herein collectively called the “Guaranteed Obligations”), and agrees to pay any and all expenses (including, without limitation, reasonable fees and expenses of counsel) incurred by the Administrative Agent or the Lenders in enforcing any rights under this Article XI. Without limiting the generality of the foregoing, the Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by the Borrower to the Administrative Agent or the Lenders under this Agreement and the other Loan Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving the Borrower. For the avoidance of doubt, each reference to a Lender in this Article XI shall include Union Bank in its capacity as a counterparty to any Interest Rate Protection Agreement.

In addition, the Guarantor hereby further agrees, as an independent obligation, that, if the Borrower fails to pay in full when expressed to be due (whether at stated maturity, upon acceleration or optional prepayment or otherwise) any of the Guaranteed Obligations strictly in accordance with the express terms hereof, the Guarantor will promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Guaranteed Obligations, the same will be paid in full when expressed to be due (whether at stated maturity, upon acceleration or optional prepayment or otherwise) in accordance with the terms of such extension or renewal.

SECTION 11.02. Obligations Unconditional. The obligations of the Guarantor under Section 11.01 are irrevocable, absolute and unconditional, irrespective of the value, genuineness, validity, regularity or enforceability of the obligations of the Borrower hereunder or under any other agreement or instrument referred to herein and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, it being the intent of this Section 11.02 that the obligations of the Guarantor hereunder shall be irrevocable, absolute and unconditional under any and all circumstances. Without limiting the generality of the foregoing, the occurrence of one or more of the following shall not preclude the exercise by the Lenders or the Administrative Agent of any right, remedy or power hereunder or alter or impair the liability of the Guarantor hereunder, which shall remain irrevocable, absolute and unconditional as described above:

(a) at any time or from time to time, without notice to the Guarantor, the time for any performance of or compliance with any of the Guaranteed Obligations shall be extended, waived or renewed, or the Borrower shall be released from any of the Guaranteed Obligations, or any of the Guaranteed Obligations shall be subordinated in right of payment to any other liability of the Borrower;

The Guarantor hereby expressly waives diligence, presentment, demand of payment, protest and all notices whatsoever, and any requirement that the Lenders or the Administrative Agent exhaust any right, power or remedy (including filing any proof of claim relating to the Guaranteed Obligations in any Insolvency Proceeding) or proceed against the Borrower under this Agreement, any other Loan Document or any agreement or instrument referred to herein or therein, or against any other Person under any other guarantee of, or security for, any of the Guaranteed Obligations, it being understood that this Article XI is a guarantee of payment and not just collection.

SECTION 11.03. Subrogation. The Guarantor hereby agrees that until the payment and satisfaction in full of all Guaranteed Obligations it shall not exercise any right or remedy (including the filing of any proof of claim in any Insolvency Proceeding) against the Borrower or any other guarantor or obligor in respect of any of the Guaranteed Obligations or any security therefor arising by reason of any performance by the Guarantor of its obligations under this Article XI, whether by subrogation or otherwise.

Any request from the Borrower for any amendment, waiver or consent under this Section 12.01 shall be addressed to the Administrative Agent.

SECTION 12.03. No Waiver of Remedies. No failure on the part of any Lender or the Administrative Agent to exercise, and no delay in exercising, any right hereunder or under any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 12.04. Costs, Expenses and Indemnification. (a) The Borrower agrees to pay, promptly after delivery to the Borrower of a reasonably detailed statement therefor, all reasonable costs and expenses of the Administrative Agent in connection with the preparation, negotiation, syndication, execution and delivery of the Loan Documents and any proposed modification, amendment, waiver or consent relating to any Loan Document, including the reasonable fees and disbursements of counsel to the Administrative Agent with respect thereto and with respect to the administration of, and advising the Administrative Agent as to its rights and responsibilities under, this Agreement and the other Loan Documents. The Borrower further agrees to pay, promptly after delivery to the Borrower of a reasonably detailed statement therefor, all costs and expenses of the Administrative Agent and each Lender (including the fees and disbursements of counsel to the Administrative Agent and counsel for each Lender) in connection with the enforcement (whether through negotiations, legal proceedings or otherwise) of this Agreement, the other Loan Documents and the other documents to be delivered hereunder.

(b) The Borrower shall indemnify the Administrative Agent, each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnified Person”) against, and hold each Indemnified Person harmless from, any and all losses, claims, damages, liabilities and related expenses, including the reasonable fees, charges and disbursements of any counsel for any Indemnified Person (whether or not such Indemnified Person is named as a party to any proceeding or is otherwise subjected to judicial or legal process arising from any such proceeding), incurred by or asserted against any Indemnified Person arising out of, in connection with, or as a result of (i) the execution or delivery of any Loan Document or any other agreement or instrument contemplated hereby or thereby, the performance by the parties to the Loan Documents of their respective obligations thereunder or the consummation of the transactions contemplated hereby or thereby, (ii) any Loan or the use or proposed use of the proceeds therefrom, (iii) any actual or alleged presence or release of any Hazardous Materials on or from any property owned or operated by the Borrower or any of its Affiliates, or any Environmental Liability related in any way to the Borrower or any of its Affiliates, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory; provided that such indemnity shall not, as to any Indemnified Person, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnified Person.

(c) To the extent permitted by applicable law, the Borrower shall not assert, and the Borrower 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 Loan Document or any agreement or instrument contemplated hereby, the Transactions, any Loan or the use of the proceeds thereof.

(d) The Borrower’s obligations under this Section 12.04 shall survive the repayment of all amounts owing to the Lenders and the Administrative Agent under the Loan Documents and the termination of the Commitments. If and to the extent that the obligations of the Borrower under this Section 12.04 are unenforceable for any reason, the Borrower agrees to make the maximum contribution to the payment and satisfaction thereof which is permissible under applicable law, which contribution shall in any event not exceed the amount that the Borrower would otherwise have been obligated to pay under this Section 12.04.

SECTION 12.05. Right of Set-off. (a) Upon (i) the occurrence and during the continuance of any Event of Default and (ii) the making of the request or the granting of the consent specified by Section 9.02 to authorize the Administrative Agent to declare the principal amount outstanding hereunder to be due and payable pursuant to the provisions of Section 9.02, each Lender is hereby authorized at any time and from time to time, 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 Lender to or for the credit or the account of the Borrower or, prior to the occurrence of the Guaranty Termination Date, the Guarantor, against any and all of the obligations of the Borrower or the Guarantor, respectively, to such Lender existing under any Loan Document and any Promissory Notes held by such Lender, irrespective of whether or not such Lender shall have made any demand under such Loan Document or such Promissory Notes, as the case may be, and although such obligations may be unmatured. Each Lender agrees to notify promptly the Borrower or the Guarantor (as applicable) after any such set-off and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender under this Section 12.05 are in addition to other rights and remedies (including other rights of set-off) which such Lender may have.

(b) The Borrower agrees that it shall have no right of off-set, deduction or counterclaim in respect of its obligations hereunder, and that the obligations of the Lenders hereunder are several and not joint. Nothing contained herein shall constitute a relinquishment or waiver of the Borrower’s rights to any independent claim that the Borrower may have against the Administrative Agent or any Lender for the Administrative Agent’s or such Lender’s, as the case may be, gross negligence or willful misconduct, but no Lender shall be liable for any such conduct on the part of the Administrative Agent or any other Lender, and the Administrative Agent shall be liable for any such conduct on the part of any Lender.

SECTION 12.06. Binding Effect. This Agreement shall become effective when it shall have been executed by the Obligors and the Administrative Agent and when the Administrative Agent shall have been notified by each Lender that such Lender has executed it and thereafter shall be binding upon and inure to the benefit of the Obligors, the Administrative Agent and each Lender and their respective successors and assigns, except that no Obligor shall have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lenders.

SECTION 12.07. Assignments and Participation. (a) Each Lender may, with the consent of the Borrower and the Administrative Agent (such consent not to be unreasonably withheld or delayed and, in the case of the Borrower, shall not be required if an Event of Default has occurred and is continuing), assign to one or more banks or other financial institutions all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including the Loans owing to it and any Promissory Notes held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all of the assigning Lender’s rights and obligations under this Agreement, (ii) the amount of the Loans of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Lender Assignment with respect to such assignment) shall in no event be less than the lesser of the aggregate amount of such Lender’s Loans and $5,000,000, (iii) each such assignment shall be to an Eligible Assignee, and (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, a Lender Assignment, together with any Promissory Notes subject to such assignment and a

processing and recordation fee (payable by the assigning Lender or such assignee) of $3,500; and provided further, however, that the consent of the Borrower and the Administrative Agent shall not be required for any assignments by a Lender to any of its Affiliates or to any other Lender or any of its Affiliates. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Lender Assignment, which effective date shall be at least five Business Days after the execution thereof (or such earlier date acceptable to the Administrative Agent), (A) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Lender Assignment, have the rights and obligations of a Lender hereunder and (B) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it to an Eligible Assignee pursuant to such Lender Assignment, relinquish its rights and be released from its obligations under this Agreement (and, in the case of a Lender Assignment covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto); provided, however, that the limitation set forth in clause (iii) above shall not apply if an Event of Default shall have occurred and be continuing and the Administrative Agent shall have declared any Loans to be, or any Loans shall have automatically become, immediately due and payable hereunder. Notwithstanding anything to the contrary contained in this Agreement, any Lender may at any time assign all or any portion of the Loans owing to it to any Affiliate of such Lender. No such assignment, other than to an Eligible Assignee in accordance with this Section 12.07, shall release the assigning Lender from its obligations hereunder.

(b) By executing and delivering a Lender Assignment, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Lender Assignment, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with any Loan Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document or any other instrument or document furnished pursuant thereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of any Obligor or the performance or observance by any Obligor of any of its obligations under any Loan Document or any other instrument or document furnished pursuant thereto; (iii) such assignee confirms that it has received a copy of each Loan Document, together with copies of the financial statements referred to in Section 7.01(d) of this Agreement and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Lender Assignment; (iv) such assignee will, independently and without reliance upon the Administrative Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Loan Documents; (v) such assignee confirms that it is an Eligible Assignee (unless an Event of Default shall have occurred and be continuing and the Administrative Agent shall have declared any Loans to be immediately due and payable hereunder, in which case no such confirmation is necessary); (vi) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under the Loan Documents as are delegated to the Administrative Agent by the terms thereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of the Loan Documents are required to be performed by it as a Lender.

(c) The Administrative Agent shall maintain at its address referred to in Section 12.02 a copy of each Lender Assignment delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Obligors, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) Upon its receipt of a Lender Assignment executed by an assigning Lender and an assignee representing that it is an Eligible Assignee (unless an Event of Default shall have occurred and be continuing and the Administrative Agent shall have declared any Loans to be immediately due and payable hereunder, in which case no such representation is necessary), together with any Promissory Notes subject to such assignment, the processing and recordation fee referred to in subsection (a) above and any written consent to such assignment required by subsection (a) above, the Administrative Agent shall, if such Lender Assignment has been completed and is in substantially the form of Exhibit D, (i) accept such Lender Assignment, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower. New and/or replacement Promissory Notes payable to the assignee and the assigning Lender (if the assigning Lender assigned less than all of its rights and obligations hereunder) shall be issued upon request pursuant to Section 3.08 and shall be dated the effective date of such Lender Assignment.

(e) Each Lender may sell participations to one or more banks or other financial institutions (other than, for the avoidance of doubt, the Borrower or any Affiliate or Subsidiary of the Borrower) (a “Participant”) in or to all or a portion of its rights and obligations under the Loan Documents (including all or a portion of the Loans owing to it and any Promissory Notes held by it); provided, however, that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any such Promissory Notes for all purposes of this Agreement, and (iv) the Obligors, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and the other Loan Documents and to approve any amendment, modification or waiver of any provision of this Agreement or any other Loan Document; provided, that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 12.01 that affects such Participant. Subject to subsection (f) below, the Obligors agree that each Participant shall be entitled to the benefits of Sections 4.04, 5.01 and 5.03 (and subject to the related obligations under such Sections) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (a) above. To the extent permitted by law, each Participant shall also be entitled to the benefits of Section 12.05(a) as though it were a Lender, provided such Participant agrees to be subject to Section 4.03 as though it were a Lender.

(f) A Participant shall not be entitled to receive any greater payment under Section 4.04, 5.01 or 5.03 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 4.04 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 4.04 as though it were a Lender.

(g) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 12.07, disclose to the assignee or Participant or proposed assignee or Participant, any information relating to the Obligors furnished to such Lender by or on behalf of any Obligor; provided that prior to any such disclosure, the assignee or Participant or proposed assignee or Participant shall agree, in accordance with the terms of Section 12.08, to preserve the confidentiality of any Confidential Information received by it from such Lender.

(h) If any Lender (or any Participant to which such Lender has sold a participation) shall make any demand for payment under Section 5.01, then within 30 days after any such demand (if, but only if, such demanded payment has been made by the Borrower), the Borrower may, with the approval of the Administrative Agent (which approval shall not be unreasonably withheld) and provided that no Default or Event of Default shall then have occurred and be continuing, demand that such Lender assign, at the sole cost and expense of the Borrower, in accordance with this Section 12.07 to one or more Eligible Assignees designated by the Borrower, all (but not less than all) of the Loans owing to such Lender within the period ending on the later to occur of (x) the last day of the 30-day period described above and (y) the last day of the longest of the then current Interest Periods for such Loans. If any such Eligible Assignee designated by the Borrower shall fail to consummate such assignment on terms acceptable to such Lender, or if the Borrower shall fail to designate any such Eligible Assignees for all or part of such Lender’s Loans, then such demand by the Borrower shall become ineffective; it being understood for purposes of this subsection (h) that such assignment shall be conclusively deemed to be on terms acceptable to such Lender, and such Lender shall be compelled to consummate such assignment to an Eligible Assignee designated by the Borrower, if such Eligible Assignee (1) shall agree to such assignment by entering into a Lender Assignment with such Lender and (2) shall offer compensation to such Lender in an amount equal to all amounts then owing by the Borrower to such Lender hereunder and under any Promissory Notes held by such Lender, whether for principal, interest, fees, costs or expenses (other than the demanded payment referred to above, and payable by the Borrower as a condition to the Borrower’s right to demand such assignment) or otherwise (including, without limitation, to the extent not paid by the Borrower, any payments required pursuant to Section 5.03). Notwithstanding anything set forth above in this subsection (h) to the contrary, the Borrower shall not be entitled to compel the assignment by any Lender demanding payment under Section 5.01 of its Loans if, prior to or promptly following any such demand by the Borrower, such Lender shall have changed or shall change, as the case may be, its Applicable Lending Office for its Eurodollar Rate Loans so as to eliminate the further incurrence of such increased cost. In furtherance of the foregoing, any such Lender demanding payment or giving notice as provided above agrees to use reasonable efforts to so change its Applicable Lending Office if, to do so, would not result in the incurrence by such Lender of additional costs or expenses which it deems material or, in the sole judgment of such Lender, be inadvisable for regulatory, competitive or internal management reasons.

(i) Anything in this Section 12.07 to the contrary notwithstanding, any Lender may assign and pledge all or any portion of the Loans owing to it to any Federal Reserve Bank (and its transferees) as collateral security pursuant to Regulation A of the Board and any Operating Circular issued by such Federal Reserve Bank. No such assignment shall release the assigning Lender from its obligations hereunder.

(j) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to fund all or any part of any Loan that such Granting Lender would otherwise be obligated to fund pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan, and (ii) nothing herein shall excuse any Granting Lender from its obligations hereunder. The funding of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were funded by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would otherwise be liable for so long as, and to the extent, the Granting Lender provides such indemnity or makes such payment. In furtherance of the foregoing, each Lender hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other Person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this subsection (j), any SPC may, with prior notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Lender or to any financial institutions (consented to by the Borrower and the Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans. This subsection (j) may not be amended without the prior written consent of each Granting Lender, all or any part of whose Loans are being funded by an SPC at the time of such amendment. Notwithstanding the foregoing provisions of this subsection, (1) an SPC shall not be deemed to be a Lender or a Participant and shall have no rights under this Agreement except as provided in this subsection (j), and in particular, but not by way of limitation, shall have no rights to compensation for increased costs pursuant to Section 4.04 or Section 5.01, (2) the Granting Lender’s obligations under this Agreement (including its Commitment to the Borrower hereunder) shall remain unchanged, (3) the Granting Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (4) the Granting Lender shall remain the holder of any Promissory Notes for all purposes of this Agreement, (5) the Obligors, the Administrative Agent and the other Lenders shall continue to deal solely and directly with the Granting Lender in connection with such Granting Lender’s rights and obligations under this Agreement, and (6) the Granting Lender shall indemnify and hold the Borrower harmless from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be incurred or shall arise as a result of any grant to an SPC contemplated hereunder.

SECTION 12.08. Confidentiality. In connection with the negotiation and administration of this Agreement and the other Loan Documents, each Obligor has furnished and will from time to time furnish to the Administrative Agent and the Lenders (each, a “Recipient”) written information which is identified to the Recipient when delivered as confidential (such information, other than any such information which (a) was publicly available, or otherwise known to the Recipient, at the time of disclosure, (b) subsequently becomes publicly available other than through any act or omission by the Recipient or (c) otherwise subsequently becomes known to the Recipient other than through a Person whom the Recipient knows to be acting in violation of his or its obligations to any Obligor, being hereinafter referred to as “Confidential Information”). The Recipient will not knowingly disclose any such Confidential Information to any third party (other than to those persons who have a confidential relationship with the Recipient), and will take all reasonable steps to restrict access to such information in a manner designed to maintain the confidential nature of such information, in each case until such time as the same ceases to be Confidential Information or as any Obligor may otherwise instruct. It is understood, however, that the foregoing will not restrict the Recipient’s ability to freely exchange such Confidential Information with its Affiliates or with prospective participants in or assignees of the Recipient’s position herein, but the Recipient’s ability to so exchange Confidential Information shall be conditioned upon any such Affiliate’s or prospective participant’s or assignee’s (as the case may be) entering into an agreement as to confidentiality similar to this Section 12.08. It is further understood that the foregoing will not prohibit the disclosure of any or all Confidential Information if and to the extent that such disclosure may be required (i) by a regulatory agency or otherwise in connection with an examination of the Recipient’s records by appropriate authorities, (ii) pursuant to court order, subpoena or other legal process, (iii) otherwise as required by law, or (iv) in order to protect such Recipient’s interests or its rights or remedies hereunder or under the other Loan Documents; in the event of any required disclosure under clause (ii), (iii) or (iv), above, the Recipient agrees to use reasonable efforts to inform the Obligors as promptly as practicable to the extent not prohibited by law.

SECTION 12.09. WAIVER OF JURY TRIAL. THE BORROWER, THE GUARANTOR, THE ADMINISTRATIVE AGENT AND THE LENDERS EACH HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY OTHER INSTRUMENT OR DOCUMENT DELIVERED HEREUNDER OR THEREUNDER.

SECTION 12.10. Governing Law; Submission to Jurisdiction. This Agreement and the other Loan Documents shall be governed by, and construed in accordance with, the laws of the State of New York. The Borrower, the Guarantor, the Lenders and the Administrative Agent each (a) irrevocably submits to the non-exclusive jurisdiction of any New York State court or Federal court sitting in New York City in any action arising out of any Loan Document, (b) agrees that all claims in such action may be decided in such court, (c) waives, to the fullest extent it may effectively do so, the defense of an inconvenient forum and (d) consents to the service of process by mail. A final judgment in any such action shall be conclusive and may be enforced in other jurisdictions. Nothing herein shall affect the right of any party to serve legal process in any manner permitted by law or affect its right to bring any action in any other court.

SECTION 12.11. Relation of the Parties; No Beneficiary. No term, provision or requirement, whether express or implied, of any Loan Document, or actions taken or to be taken by any party thereunder, shall be construed to create a partnership, association, or joint venture between such parties or any of them. No term or provision of the Loan Documents shall be construed to confer a benefit upon, or grant a right or privilege to, any Person other than the parties hereto. The Obligors hereby acknowledge that none of the Administrative Agent or the Lenders has any fiduciary relationship with or fiduciary duty to any Obligor arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between the Administrative Agent and the Lenders, on the one hand, and the Obligors, on the other hand, in connection herewith or therewith is solely, with respect to the Borrower, that of creditor and debtor and, with respect to the Guarantor, that of beneficiary and guarantor.

SECTION 12.12. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same Agreement.

SECTION 12.13. Survival of Agreement. All covenants, agreements, representations and warranties made herein and in the certificates pursuant hereto shall be considered to have been relied upon by the Administrative Agent and the Lenders and shall survive the making by the Lenders of the Loans and the execution and delivery to the Lenders of any Promissory Notes evidencing the Loans and shall continue in full force and effect so long as any Promissory Note or any amount due hereunder or under any other Loan Document is outstanding and unpaid.

SECTION 12.14. Patriot Act Notice. Each Lender and the Administrative Agent (for itself and not on behalf of any other party) hereby notifies the Obligors that, pursuant to the requirements of the USA Patriot Act, Title III of Pub. L. 107-56, signed into law October 26, 2001 (the “Patriot Act”), it is required to obtain, verify and record information that identifies each Obligor, which information includes the name and address of each Obligor and other information that will allow such Lender or the Administrative Agent, as applicable, to identify each Obligor in accordance with the Patriot Act.

Ladies and Gentlemen:

We are counsel to UNS Electric, Inc., an Arizona corporation (the “Company”), and UniSource Energy Services, Inc., an Arizona corporation (the “Guarantor”, and together with the Company, the “Obligors” and each an “Obligor”), and have acted as such in connection with the $30,000,000 Credit Agreement, dated as of August 10, 2011, among the Company, as borrower, the Guarantor, the Lenders party thereto and Union Bank, N.A., as Administrative Agent (hereinafter, the “Credit Agreement”). Unless otherwise specified herein, capitalized terms used herein have the respective meanings set forth in the Credit Agreement.

In so acting we have reviewed all corporate proceedings of the Obligors in connection with the authorization, execution and delivery of the Credit Agreement. We have also examined such other documents and satisfied ourselves as to such other matters as we have deemed necessary as a basis for the opinions set forth below. We have relied as to various questions of fact upon the representations and warranties of the Obligors contained in the Credit Agreement and in the certificates of public officials and officers of the Obligors delivered thereunder.

Based upon and subject to the foregoing, and subject also to the qualifications hereinafter set forth, we are of the opinion that:

1. Each Obligor (a) is a corporation duly organized, validly existing and in good standing under the laws of the State of Arizona and (b) has the corporate power and authority to own and operate its property and to conduct the business in which it is currently engaged.

Union Bank, N.A.
August 10, 2011

2. Each Obligor has the corporate power and authority to execute, deliver and perform the Credit Agreement and the Company has the corporate power and authority to borrow under the Credit Agreement and each Obligor has taken all necessary corporate action to authorize the execution, delivery and performance of the Credit Agreement, and the Company has taken all necessary corporate action to authorize the borrowings under the Credit Agreement.

3. The Credit Agreement has been duly and validly executed and delivered on behalf of each Obligor party thereto and constitutes the legal, valid and binding obligation of each Obligor, enforceable against each Obligor in accordance with its terms except as enforceability may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium or similar laws relating to or affecting the enforcement of creditors’ rights generally, including, without limitation, laws relating to fraudulent transfers or conveyances, preferences and equitable subordination, and by general equitable principles (regardless of whether such enforceability is considered in a proceeding in equity or at law), and subject to any principles of public policy limiting the right to enforce indemnification or contribution provisions contained in the Credit Agreement with respect to liabilities under federal or state securities laws.

4. No consent or authorization of, filing with or other act by or in respect of, any Governmental Authority of the State of New York, the Federal Energy Regulatory Commission (“FERC”) or the Arizona Corporation Commission (“ACC”) is required in connection with the execution, delivery or performance by any Obligor of the Credit Agreement, or for borrowings by the Company under the Credit Agreement, except for the ACC Order (which has been obtained and is, to the best of our knowledge, in full force and effect); provided, however, that we express no opinion in this paragraph as to compliance with the securities or “blue sky” laws of any jurisdiction.

5. The execution, delivery and performance by each Obligor of the Credit Agreement, and the borrowings under the Credit Agreement, will not (i) violate any applicable law of the State of New York or any law administered by, or any rule or regulation of, the FERC or the ACC, (ii) violate the Articles of Incorporation or the Bylaws, as amended, of such Obligor, or (iii) result in, or require, the creation or imposition of any Lien on any of the properties or revenues of such Obligor other than as contemplated by the Credit Agreement.

6. Each Obligor is not an “investment company”, or a company “controlled” by an “investment company”, within the meaning of the Investment Company Act of 1940, as amended.

This opinion is limited to the laws of the States of Arizona and New York and the federal laws of the United States of America. As to all matters of Arizona law, we have, with your consent, relied upon the opinion of even date herewith rendered to you by ▇▇▇▇ ▇. ▇▇▇▇▇, Vice President and General Counsel of the Guarantor, and the opinions expressed herein upon such reliance are subject to the same assumptions, qualifications and limitations set forth therein.

Ladies and Gentlemen:

I am Vice President and General Counsel of UniSource Energy Services, Inc., an Arizona corporation (the “Guarantor”), and Vice President and Secretary of UNS Electric, Inc., an Arizona corporation (the “Company”, and together with the Guarantor, the “Obligors” and each an “Obligor”), and have acted as such in connection with the $30,000,000 Credit Agreement, dated as of August 10, 2011, among the Company, as borrower, the Guarantor, the Lenders party thereto and Union Bank, N.A., as Administrative Agent (hereinafter, the “Credit Agreement”).

5. The execution, delivery and performance by each Obligor of the Credit Agreement, and the borrowings under the Credit Agreement, will not (i) violate any law, rule or regulation of any Governmental Authority, which, in my experience, is normally applicable to transactions of the type contemplated thereby or to entities similar to such Obligor, (ii) violate any order of any Governmental Authority of which I have knowledge, (iii) violate the Articles of Incorporation or the Bylaws, as amended, of such Obligor, (iv) violate or result in a default under any indenture, agreement or other instrument of which I have knowledge binding upon any Obligor or its assets, or (v) result in, or require, the creation or imposition of any Lien on any of the properties or revenues of such Obligor other than as contemplated by the Credit Agreement.

6. Except as disclosed in the Disclosure Documents, there are no actions, suits or proceedings by or before any arbitrator, referee or Governmental Authority pending against or, to my knowledge, threatened against or affecting any of the Obligors (a) as to which there is, in my judgment, a reasonable possibility of an adverse determination and that, if adversely determined, would individually or in the aggregate, in my judgment, result in a Material Adverse Effect or (b) that involves the Credit Agreement, or any transactions contemplated therein.

Except as disclosed in the Disclosure Documents, and except with respect to any other matters that, individually or in the aggregate, could not, in my judgment, reasonably be expected to result in a Material Adverse Effect, to my knowledge none of the Obligors (a) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval required under any Environmental Law, (b) has become subject to any Environmental Liability, (c) has received notice of any claim with respect to any Environmental Liability or (d) knows of any basis for any Environmental Liability.

Notwithstanding the foregoing, if the Index Debt is split-rated and the ratings differential is two or more ratings levels, the Status shall be determined assuming that (a) the higher rating is equal to the midpoint of the two ratings (e.g., for a split rating of BBB+/Baa3, BBB is the midpoint and will be deemed to be the higher rating, and for a split rating of BB/Baa1, Baa3 is the midpoint and will be deemed to be the higher rating) or (b) if there is no exact midpoint, the higher rating is equal to the higher of the two middle intermediate ratings (e.g., for a split rating of BBB+/Ba1, BBB is the higher of the two middle intermediate ratings and will be deemed to be the higher rating, and for a split rating of BB/Baa2, Baa3 is the higher of the two middle intermediate ratings and will be deemed to be the higher rating).

If at any time the Index Debt is unrated by both ▇▇▇▇▇’▇ and S&P, Level 3 Status shall exist; provided that if the reason that there is no such ▇▇▇▇▇’▇ rating or S&P rating results from ▇▇▇▇▇’▇ or S&P, as the case may be, ceasing to issue debt ratings generally, then the Borrower and the Administrative Agent may select another nationally-recognized rating agency to substitute for ▇▇▇▇▇’▇ or S&P, as applicable, for purposes of this Pricing Schedule (and all references herein to ▇▇▇▇▇’▇ or S&P, as applicable, shall refer to such substitute rating agency), and until a substitute nationally-recognized rating agency is so selected the Status shall be determined by reference to the rating most recently in effect prior to such cessation; and provided, further, that if the Index Debt is rated by only one of ▇▇▇▇▇’▇ or S&P, the Status shall be determined by reference to the rating of such Rating Agency.

The Applicable Margin (and, accordingly, the Status of the Borrower at any date) shall be based on the applicable ratings in effect from time to time on the Index Debt. The Applicable Margin shall be increased or decreased in accordance with the foregoing Pricing Schedule upon any change in the applicable ratings of the Index Debt. The ratings of the Index Debt in effect at any date is that in effect at the close of business on such date.
