ARTICLE 2 LOANS ----- Section 2.1 Commitment. UBOC hereby agrees, on the terms and conditions set forth in this Agreement, to make up to two loans ("Loans") to the Borrower, each comprising a Borrowing, on the Effective Date and/or on the first Business Day thereafter, in amount(s) requested by the Borrower whose total does not exceed the Commitment. Upon the making of - 14 - Loan(s) pursuant to this Section, the unused portion, if any, of the Commitment shall terminate. Amounts borrowed hereunder and prepaid or otherwise repaid may not be reborrowed. Section 2.2 Borrowing. (a) Subject to Section 2.10, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans, as the Borrower may request in accordance herewith. Each Lender, at its option, may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided, however, that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement. (b) At the commencement of each Interest Period for each Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is not less than $5,000,000 in increments of $1,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is not less than $5,000,000 in increments of $1,000,000. Borrowings of more than one Type may be outstanding at the same time; provided, however, that there shall not at any time be more than a total of five Eurodollar Borrowings outstanding. (c) Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to elect to convert to or continue a Eurodollar Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date. Section 2.3 Request for Borrowing. To request a Loan pursuant to Section 2.1, the Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Loan, not later than 12:00 noon, California time, three Business Days before the date of the proposed Loan or (b) in the case of an ABR Loan, not later than 12:00 noon, California time, on the day of the proposed Loan. Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request in a form approved by the Administrative Agent and signed by the Borrower. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.2: (i) the amount of the requested Loan; (ii) the date of such Loan, which shall be a Business Day; (iii) whether such Loan is to be an ABR Loan or a Eurodollar Loan; (iv) in the case of a Eurodollar Loan, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term "Interest Period"; and (v) the location and number of the Borrower's account to which funds are to be disbursed, which shall comply with the requirements of Section 2.4. If no election as to the Type of Loan is specified, then the requested Loan shall be an ABR Loan. If no Interest Period is specified with respect to any requested Eurodollar Loan, then the Borrower shall be deemed to have selected an Interest Period of one month's duration. Section 2.4 Funding of Borrowings. The Administrative Agent will make the initial Loan(s) to the Borrower pursuant to Section 2.1 by wire-transferring the amount(s) thereof, in immediately available funds, to an account of the Borrower designated thereby in the applicable Borrowing Request. - 15 - Section 2.5 Interest Elections. (a) Each Borrowing made pursuant to Section 2.1 shall initially be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. (b) To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone (i) in the case of continuation of, or conversion to, a Eurodollar Borrowing, not later than 12:00 noon, California time, three Business Days before the date of the proposed continuation or conversion or (ii) in the case of conversion to an ABR Borrowing, not later than 12:00 noon, California time, one Business Day before the date of the proposed conversion. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request. (c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.2: (i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing); (ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day; (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and (iv) if the resulting Borrowing is to be a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term "Interest Period." If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month's duration. (d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender's portion of each resulting Borrowing. (e) If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a - 16 - Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto. Section 2.6 Repayment of Loans; Evidence of Debt. (a) The Borrower hereby unconditionally promises to pay to the Administrative Agent on the Maturity Date, for the account of each Lender, the then unpaid principal amount of each Loan. (b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. (c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender's share thereof. (d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided, however, that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement. (e) Any Lender may request that Loans made by it 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 9.4) 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 2.7 Optional Prepayment of Loans. (a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with paragraph (b) of this Section. (b) The Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder not later than 12:00 noon, California time, three Business Days before the date of prepayment. Each such notice shall be irrevocable and - 17 - shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid. Promptly following receipt of any such notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.2. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Section 2.8 Mandatory Prepayment of Loans. (a) If the acquisition by UniSource Energy Services, through two wholly owned Subsidiaries thereof, of the Arizona electric-utility and gas-utility businesses currently owned by Citizens Communications is not consummated in accordance with the terms of the Acquisition Agreement, without any waiver or amendment not consented to by the Administrative Agent of any term, provision or condition set forth therein and in compliance with all applicable law, by August 15, 2003, the Borrower will repay the outstanding Loans in full on that date. (b) The Borrower will, within three Business Days after each date of receipt by the Borrower or any Subsidiary of Net Cash Proceeds from (i) the sale, transfer or other disposition by the Borrower or any Subsidiary of any direct or indirect interest in, or rights with respect to, Springerville Unit 3, including the contemplated assignment from Tucson Electric to Tri-State of certain development and other rights with respect to Springerville Unit 3, (ii) the sale or issuance, in any capital markets transaction, of any debt securities of or equity interests in the Borrower or any warrants, options or other rights to acquire any such equity interest or (iii) the sale or issuance, in any capital markets transaction, of any debt securities of UniSource Energy Services and/or any one or more Subsidiaries of UniSource Energy Services after August 11, 2003 (but excluding in any case a loan in an amount up to $21,000,000 that may be made by the Borrower to a Subsidiary of UniSource Energy Services from the proceeds of the Loans), prepay an aggregate principal amount of Loans composing all or part of the same Borrowings equal to 100% of the amount of such Net Cash Proceeds. Section 2.9 Interest. (a) The Loans comprising each ABR Borrowing shall bear interest at the rate equal at all times to the sum of the Alternate Base Rate plus 3.875% per annum. (b) The Loans comprising each Eurodollar Borrowing shall bear interest during each Interest Period for such Loans at the rate equal to the sum of the Adjusted LIBO Rate for such Interest Period plus 4.875% per annum. (c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% per annum plus the rate otherwise applicable to such Loan as provided in the preceding - 18 - paragraphs of this Section or (ii) in the case of any other amount, 2% per annum plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section. (d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon the Maturity Date; provided, however, that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion. (e) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Reference Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate or Adjusted LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error. Section 2.10 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing, (a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or LIBO Rate, as applicable, for such Interest Period or (b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period, then (i) the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter, and (ii) until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective. Section 2.11 Increased Costs. (a) If any Change in Law shall (i) impose, modify or deem applicable any reserve, special-deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate, where applicable) or (ii) impose on any Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender, and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or otherwise), then the Borrower will pay to the Administrative Agent, for the account of such Lender, such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered. - 19 - (b) If any Lender determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender's capital or on the capital of such Lender's holding company, if any, as a consequence of this Agreement or the Loans made by such Lender, to a level below that which such Lender or such Lender's holding company could have achieved but for such Change in Law (taking into consideration such Lender's policies and the policies of such Lender's holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender's holding company for any such reduction suffered. (c) A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. (d) 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, however, 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 Change in Law giving rise to such increased costs or reductions and of such Lender's intention to claim compensation therefor; further provided, however, that, if the Change in Law 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 2.12 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of any prepayment of a Eurodollar Loan, whether as a result of the occurrence of an Event of Default or otherwise), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Loan on the date specified in any notice delivered pursuant hereto or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.15, then, in any such event, the Borrower shall compensate each applicable Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost and expense to any applicable Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the Eurodollar market. A certificate of any - 20 - Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. Section 2.13 Taxes. (a) Any and all payments by or on account of any obligation of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided, however, that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent or Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. (b) The Borrower shall indemnify the Administrative Agent and each Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder or under any other Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender, or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. (c) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. (d) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or under any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate. (e) In addition, the Borrower or the Administrative Agent shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. - 21 - Section 2.14 Payments Generally; Pro Rata Treatment; Sharing of Setoffs. (a) The Borrower shall make each payment required to be made by it hereunder or under any other Loan Document (whether of principal or interest, or of amounts payable under Section 2.11, 2.12 or 2.13, or otherwise) prior to 1:00 p.m., California time, on the date when due, in immediately available funds, without setoff, counterclaim, recoupment or deduction of any kind. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at 445 South Figueroa Street, Suite 1500, Los Angeles, California, except that payments pursuant to Sections 2.11, 2.12, 2.13 and 9.3 shall be made directly to the Persons entitled thereto, and payments pursuant to other Loan Documents shall be made to the Persons specified therein. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder or under any other Loan Document shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments under each Loan Document shall be made in dollars. (b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal and interest then due hereunder, such funds shall be applied (i) first, towards payment of interest then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest then due to such parties, and (ii) second, towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties. (c) If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided, however, that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of setoff and counterclaim with respect to such - 22 - participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry practice on interbank compensation. (e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.14(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender's obligations under such Sections until all such unsatisfied obligations are fully paid. Section 2.15 Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.11, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.13, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.11 or 2.13, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. (b) If any Lender requests compensation under Section 2.11, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.13, or if any Lender defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.4), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided, however, that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon and all other amounts payable to it hereunder, from the assignee (to the extent of - 23 - such outstanding principal and accrued interest) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.11 or payments required to be made pursuant to Section 2.13, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. Section 2.16 Illegality. Notwithstanding any other provision of this Agreement, if any Change in Law makes it unlawful, or any Governmental Authority asserts that it is unlawful, for any Lender to perform its obligations hereunder to make, continue or convert into Eurodollar Loans, 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, continue or convert into Eurodollar Loans shall be suspended until the Administrative Agent notifies the Borrower that such Lender has determined that the circumstances causing such suspension no longer exist, and (b) the Borrower will forthwith prepay in full all Eurodollar Loans of such Lender then outstanding, together with accrued and unpaid interest thereon, unless the Borrower, within five Business Days of such notice and demand, converts all Eurodollar Loans of all Lenders then outstanding into ABR Loans in accordance with the terms hereof.

ARTICLE 8 THE ADMINISTRATIVE AGENT ------------------------ Section 8.1 Authorization. Each of the Lenders hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms of the Loan Documents, together with such actions and powers as are reasonably incidental thereto. - 40 - Section 8.2 Administrative Agent and Affiliates. The bank serving as the 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 bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not the Administrative Agent hereunder. Section 8.3 Duties of Administrative Agent. 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, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) 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 9.2), and (c) 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 Borrower or any of its Subsidiaries that is communicated to or obtained by the bank 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 9.2) 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 unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article 4 or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. Section 8.4 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it, whether orally (including by telephone) or in writing (in any medium), and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. - 41 - Section 8.5 Sub-Agents. The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub- agent may perform any and all of the Administrative Agent's duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of this Article 8 shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. Section 8.6 Successor Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided in this Section, the Administrative Agent may resign at any time by notifying the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor; provided, however, that no such consultation shall be required if a Default has occurred and is continuing. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be a bank. Upon the acceptance by a successor of its appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent's resignation hereunder, the provisions of this Article and Section 9.3 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 the retiring Administrative Agent was acting as Administrative Agent. Section 8.7 Lender Credit Decision. 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 related agreement, or any document furnished hereunder or thereunder. ARTICLE 9 MISCELLANEOUS ------------- Section 9.1 Notices. Except in the case of notices and other communications expressly permitted to be given by telephone, all notices and other communications provided for - 42 - herein shall be in writing and shall be delivered by hand or overnight courier service, mailed by certified or registered mail or sent by telecopy, as follows: (a) if to the Borrower, to it at One South Church Avenue, Tucson, Arizona 85701, Attention of Chief Financial Officer (Telecopy No. (520) 884-3612); (b) if to the Administrative Agent, to it at 445 South Figueroa Street, Los Angeles, California 90071, Attention of Energy Capital Services (Telecopy No. (213) 629-1033); and (c) if to any Lender, to it at its address (or telecopy number) set forth on its signature page hereto or in the Assignment and Acceptance by which it becomes a party to this Agreement. Any party hereto may change its address or telecopy number for notices and other communications hereunder by notice to the other parties hereto. All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt. Section 9.2 Waivers; Amendments. (a) No failure or delay by the Administrative Agent or any Lender in exercising any right or power hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent or any Lender may have had notice or knowledge of such Default at the time. (b) Neither this Agreement nor any other Loan Document nor any provision hereof or thereof may be waived, amended or modified except, in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders or, in the case of any other Loan Document (other than a promissory note issued hereunder or fee agreement entered into pursuant hereto), pursuant to an agreement or agreements in writing entered into by the Administrative Agent and the Borrower, in each case with the consent of the Required Lenders; provided, however, that no such agreement shall (i) increase the Commitment without the written consent of UBOC, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon without the written consent of each - 43 - Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan, or any interest thereon, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of the Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.14(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change any of the provisions of this Section or the definition of "Required Lenders" or any other provision of any Loan Document specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender, or (vi) release all or substantially all of the Collateral from the Liens of the Stock Pledge Agreement without the consent of each Lender; further provided, however, that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent hereunder without the prior written consent of the Administrative Agent. Section 9.3 Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay (i) all reasonable out-of- pocket expenses incurred by the Administrative Agent, the Arranger and their Affiliates (including due diligence expenses and the reasonable fees, charges and disbursements of counsel for the Administrative Agent) in connection with the arrangement and syndication of the credit facilities provided for herein, the preparation, execution, delivery and administration of the Loan Documents or any amendments, modifications or waivers of the provisions thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all out-of-pocket expenses and charges of the Administrative Agent in connection with any evaluations of Collateral conducted by it, (iii) all out-of-pocket expenses incurred by the Administrative Agent or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent or any Lender, in connection with the enforcement or protection of its rights in connection with the Loan Documents, including its rights under this Section, or in connection with the Loans made hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of the Loans. (b) The Borrower shall indemnify the Administrative Agent, the Arranger, each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an "Indemnitee") against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee 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, the performance by the parties to the Loan Documents of their respective obligations thereunder or the consummation of the Transactions or any other transactions contemplated thereby, (ii) any Loan or the use of the proceeds thereof, (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, 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 and regardless of whether any Indemnitee is a party thereto; provided, however, that such indemnity shall not, as to any Indemnitee, be available to the extent - 44 - that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by a final and nonappealable judgment to have resulted primarily from the gross negligence, willful misconduct or bad faith of such Indemnitee. (c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent or the Arranger under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent or the Arranger, as the case may be, such Lender's pro rata share (based on the Obligations owed to the Lenders at the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided, however, 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 Administrative Agent or the Arranger in its capacity as such. (d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, 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 or thereby, the Transactions, any Loan or the use of the proceeds thereof. (e) All amounts due under this Section shall be payable promptly after written demand therefor. Section 9.4 Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Arranger and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement. (b) Any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of the Loans owing to it); provided, however, that (i) except in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund of any Lender, each of the Borrower and the Administrative Agent must give its prior written consent to such assignment (which consent shall not be unreasonably withheld), (ii) except in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund of any Lender or an assignment of the entire remaining amount of the assigning Lender's Loans, the aggregate principal amount of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall be in an aggregate amount of not less than $5,000,000 unless each of the Borrower and the Administrative Agent otherwise - 45 - consents, (iii) each partial assignment by a Lender of its Loans shall be made as an assignment of a proportionate part of all the assigning Lender's rights and obligations under this Agreement in respect of its Loans and (iv) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $5,000; further provided, however, that any consent of the Borrower otherwise required under this paragraph shall not be required if an Event of Default shall have occurred and be continuing. Subject to acceptance and recording thereof pursuant to paragraph (d) of this Section, from and after the effective date specified in each Assignment and Acceptance the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, shall have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.11, 2.12, 2.13 and 9.3). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (e) of this Section. (c) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in California a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the principal amount of the Loans owing to each Lender, pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender at any reasonable time and from time to time upon reasonable prior notice. (d) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Acceptance and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. (e) Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (each a "Participant") in all or a portion of such Lender's rights and obligations under this Agreement (including all or a portion of the Loans owing to 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 and (iii) the Borrower, 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 - 46 - 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 the Loan Documents and to approve any amendment, modification or waiver of any provision of the Loan Documents; provided, however, 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 9.2(b) that affects such Participant. Subject to paragraph (f) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.11, 2.12 and 2.13 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.8 as though it were a Lender; provided, however, that such Participant agrees to be subject to Section 2.14(c) as though it were a Lender. (f) A Participant shall not be entitled to receive any greater payment under Section 2.11 or 2.13 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower's prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.13 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 2.13(d) as though it were a Lender. (g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided, however, that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. In the case of any Lender that is a fund that invests in bank loans, such Lender may, without the consent of the Borrower or Administrative Agent, assign or pledge all or any portion of its rights under this Agreement, including the Loans and any notes or other instruments evidencing its rights as a Lender under this Agreement, to any holder of, trustee for, or other representative of holders of, obligations owed or securities issued by such fund, as security for such obligations or securities; provided, however, that any foreclosure or similar action by such trustee or representative shall be subject to the provisions of Section 9.4(b) concerning assignments. Section 9.5 Survival. All covenants, agreements, representations and warranties made by the Borrower in the Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document (a) shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of the Loan Documents and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and (b) shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any other amount payable under this Agreement is outstanding and unpaid. The provisions of Sections 2.11, 2.12, 2.13 and 9.3 and Article 8 shall survive and remain in full force and effect - 47 - regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Commitment or the termination of this Agreement or any provision hereof. Section 9.6 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent or the Arranger constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.1, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement. Section 9.7 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.
