ARTICLE II THE FACILITY, BORROWING PROCEDURES AND NOTES SECTION 2.1 The Facility. SECTION 2.1.1 Description of the Facility. The Lenders grant to the Borrower a revolving credit facility (the "Facility") pursuant to which, and upon the terms and subject to the conditions herein set out and provided that no Default or Unmatured Default has occurred and is continuing from time to time on any Business Day occurring prior to the Commitment Termination Date, each Lender severally agrees to make revolving loans in U.S. Dollars (relative to such Lender, its "Revolving Loans") to the Borrower equal to such Lender's Percentage of the aggregate amount of Revolving Loans requested by the Borrower to be made on such day (the commitment of each Lender described in this Section 2.1.1 is herein referred to as its "Commitment"). In addition, each Lender may, in its sole discretion, make bids to make Competitive Bid Loans in U.S. Dollars to the Borrower in accordance with Section 2.2. No Lender shall be permitted or required to make (i) any Revolving Loan or Competitive Bid Loan if, after giving effect thereto, the aggregate outstanding principal amount of all Revolving Loans plus Competitive Bid Loans of all Lenders would exceed the Commitment Amount, and (ii) any Revolving Loan if, after giving effect thereto, the aggregate amount of all Revolving Loans of such Lender would exceed the Lender's Percentage of the Commitment Amount.

Subject to the terms of this Agreement, the Facility is available to the Borrower from the date of this Agreement to the Commitment Termination Date, and the Borrower may borrow, repay and reborrow under the Facility at any time prior to the Commitment Termination Date. 19 26 SECTION 2.2 Competitive Bid Advances. SECTION 2.2.1 Competitive Bid Option. In addition to Loans pursuant to Section 2.1, but subject to the terms and conditions of this Agreement (including, without limitation, the limitation set forth in Section 2.1.1 as to the maximum aggregate principal amount of all outstanding Loans hereunder), the Borrower may, as set forth in this Section 2.2, request the Lenders, prior to the Commitment Termination Date, to make offers to make Competitive Bid Advances to the Borrower. Each Lender may, but shall have no obligation to, make such offers and the Borrower may, but shall have no obligation to, accept any such offers in the manner set forth in this Section 2.2. SECTION 2.2.2 Competitive Bid Quote Request. The Borrower may request offers to make Competitive Bid Loans under Section 2.2 by transmitting to the Agent by telex or telecopy a Competitive Bid Quote Request so as to be received no later than (i) 10:00 a.m. (New York time) at least four Business Days prior to the Borrowing Date proposed therein, in the case of a Eurodollar Auction or (ii) 10:00 a.m. (New York time) at least one Business Day prior to the Borrowing Date proposed therein, in the case of an Absolute Rate Auction. The Competitive Bid Quote Request shall specify (i) the proposed Borrowing Date, which shall be a Business Day, for the proposed Competitive Bid Advance; (ii) the aggregate principal amount of such Competitive Bid Advance; (iii) whether the Competitive Bid Quotes requested are to set forth a Competitive Bid Margin or an Absolute Rate, or both; and (iv) the Interest Period applicable thereto (which may not end after the Commitment Termination Date). The Borrower may request offers to make Competitive Bid Loans for more than one Interest Period and for a Eurodollar Auction and an Absolute Rate Auction in a single Competitive Bid Quote Request. No Competitive Bid Quote Request shall be given within three Business Days (or upon reasonable prior notice to the Lenders, such other number of days as the Borrower and the Agent may agree) of any other Competitive Bid Quote Request. Each Competitive Bid Quote Request shall be in a minimum amount of $10,000,000 (and in integral multiples of $1,000,000 in excess thereof). A Competitive Bid Quote Request that does not conform substantially to the format of Exhibit 2.2.2 hereto shall be rejected, and the Agent shall promptly notify the Borrower of such rejection by telex or telecopy. SECTION 2.2.3 Invitation for Competitive Bid Quotes. Promptly and in any event before 1:00 p.m. (New York time) on the same Business Day of receipt of a Competitive Bid Quote Request that is not rejected pursuant to Section 2.2.2, the Agent shall send to each of the Lenders by telex or telecopy an Invitation for Competitive Bid Quotes, substantially in the form of Exhibit 2.2.3 attached hereto, which shall constitute an invitation by the Borrower to each Lender to submit Competitive Bid Quotes offering to make the Competitive Bid Loans to which such Competitive Bid Quote Request relates in accordance with Section 2.2.4. SECTION 2.2.4 Submission and Contents of Competitive Bid Quotes. (a) Each Lender may, in its sole discretion, but is under no obligation to, submit a Competitive Bid Quote containing 20 27 an offer or offers to make Competitive Bid Loans in response to any Invitation for Competitive Bid Quotes. Each Competitive Bid Quote must comply with the requirements of this Section 2.2.4 and must be submitted to the Agent by telecopy (except in the case of UBS) at its offices specified in Section 10.2 not later than (i) in the case of a Eurodollar Auction, (A) with respect to UBS, 12:45 p.m. (New York time), at least three Business Days prior to the proposed Borrowing Date and (B) with respect to each other Lender, 1:00 p.m. (New York time), at least three Business Days prior to the proposed Borrowing Date, or (ii) in the case of an Absolute Rate Auction, (A) with respect to UBS, 9:45 a.m. (New York time) on the proposed Borrowing Date and (B) with respect to each other Lender, 10:00 a.m. (New York time) on the proposed Borrowing Date (or, with respect to clauses (i) and (ii) and upon reasonable prior notice to the Lenders, such other time and date as the Borrower and the Agent may agree, provided that UBS shall submit its Competitive Bid Quote fifteen minutes before the time that the other Lenders are required to submit their Competitive Bid Quotes). (b) Each Competitive Bid Quote shall in any case specify: (i) the proposed Borrowing Date, which shall be the same as that set forth in the applicable Invitation for Competitive Bid Quotes; (ii) the principal amount of the Competitive Bid Loan for which each such offer is being made, which principal amount (1) may be greater than, less than or equal to the Commitment of the quoting Lender, (2) must be at least $10,000,000 and an integral multiple of $1,000,000, and (3) may not exceed the principal amount of Competitive Bid Loans for which offers were requested; (iii) in the case of a Eurodollar Auction, the Competitive Bid Margin offered for each such Competitive Bid Loan; (iv) the minimum or maximum amount, if any, of any Competitive Bid Loan which may be accepted by the Borrower and/or the limit, if any, as to the aggregate principal amount of Competitive Bid Loans from such Lender which may be accepted by the Borrower; (v) in the case of an Absolute Rate Auction, the Absolute Rate offered for each such Competitive Bid Loan; (vi) the applicable Interest Period; and (vii) the identity of the quoting Lender. (c) The Agent shall reject any Competitive Bid Quote that (i) is not substantially in the form of Exhibit 2.2.4 hereto or does not specify all of the information required by Section 2.2.4(ii); (ii) contains qualifying, conditional or similar language, other than any such language contained in Exhibit 2.2.4 hereto; (iii) proposes terms other than or in addition to those set forth in the applicable Invitation for Competitive Bid Quotes; or (iv) arrives after the time set forth in Section 2.2.4(i). If any Competitive Bid Quote shall be rejected pursuant to this Section 2.2.4(iii), then the Agent shall notify the relevant Lender of such rejection as soon as practical. SECTION 2.2.5 Notice to the Borrower. The Agent shall promptly notify the Borrower of the terms (i) of any Competitive Bid Quote submitted by a Lender that is in accordance with Section 2.2.4 and (ii) of any Competitive Bid Quote that is in accordance with Section 2.2.4 and amends, modifies or is otherwise inconsistent with a previous Competitive Bid Quote submitted by such Lender with respect to the same Competitive Bid Quote Request. Any such subsequent Competitive Bid Quote shall be disregarded by the Agent unless such subsequent Competitive Bid Quote specifically states that it is submitted solely to correct a manifest error in such former Competitive Bid Quote. The Agent's notice to the Borrower shall specify the aggregate principal amount of Competitive Bid Loans for which offers have been received for each Interest Period 21 28 specified in the related Competitive Bid Quote Request and the respective principal amounts and Competitive Bid Margins or Absolute Rates, as the case may be, so offered. SECTION 2.2.6 Acceptance and Notice by the Borrower. Subject to the receipt of the notice from the Agent referred to in Section 2.2.5, not later than (i) 3:00 p.m. (New York time) at least three Business Days prior to the proposed Borrowing Date, in the case of a Eurodollar Auction or (ii) 11:00 a.m. (New York time) on the proposed Borrowing Date, in the case of an Absolute Rate Auction, the Borrower shall notify the Agent of its acceptance or rejection of the offers so notified to it pursuant to Section 2.2.5; provided, however, that the failure by the Borrower to give such notice to the Agent shall be deemed to be a rejection of all such offers. In the case of acceptance, such notice (a "Competitive Bid Borrowing Notice") shall be irrevocable and shall specify the aggregate principal amount of offers for each Interest Period that are accepted. The Borrower may accept or reject any Competitive Bid Quote in whole or in part (subject to the terms of Section 2.2.4(b)(iv)); provided that (a) the aggregate principal amount of each Competitive Bid Advance may not exceed the applicable amount set forth in the related Competitive Bid Quote Request; (b) acceptance of offers for any Competitive Bid Advance with otherwise identical terms may only be made on the basis of ascending Competitive Bid Margins or Absolute Rates, as the case may be; (c) the Borrower may not accept any offer of the type described in Section 2.2.4(c) or that otherwise fails to comply with the requirements of this Agreement for the purpose of obtaining a Competitive Bid Loan under this Agreement; and (d) after giving effect to such Competitive Bid Advance, the sum of the aggregate principal amount of all outstanding Revolving Loans plus all Competitive Bid Advances shall not exceed the Commitment Amount. SECTION 2.2.7 Allocation by the Agent. If offers are made by two or more Lenders with the same Competitive Bid Margins or Absolute Rates, as the case may be, for a greater aggregate principal amount than the amount in respect of which offers are permitted to be accepted for the related Interest Period, the principal amount of Competitive Bid Loans in respect of which such offers are accepted shall be allocated by the Agent among such Lenders as nearly as possible (in such multiples, not greater than $1,000,000, as the Agent may deem appropriate) in proportion to the aggregate principal amount of such offers; provided, however, that no Lender shall be allocated a portion of any Competitive Bid Advance which is less than the minimum amount which such Lender has indicated that it is willing to accept. Allocations by the Agent of the amounts of Competitive Bid Loans shall be conclusive in the absence of manifest error. The Agent shall promptly, but in any event on the same Business Day in the case of Eurodollar Bid Rate Advances, and by 12:00 p.m. (New York time) in the case of Absolute Rate Advances, notify each Lender of its receipt of a Competitive Bid Borrowing Notice and the aggregate principal amount of such Competitive Bid Advance allocated to each participating Lender. SECTION 2.2.8 Administration Fees. The Borrower hereby agrees to pay to the Agent for its sole account administration fees for Competitive Bid Quote Requests in such amounts as heretofore agreed upon by the Borrower and the Agent in a fee letter dated December 24, 1997, as amended from time to time (the "Competitive Bid Fee Letter"). 22 29 SECTION 2.2.9 Reduction. While any Competitive Bid Advances are outstanding, each Lender's Commitment shall be reduced by, and deemed used in the amount of its pro rata share (based on its respective Percentage of the Commitment Amount) of the outstanding amount of such Competitive Bid Advances. SECTION 2.3 Reduction of Commitment Amount. The Borrower may, from time to time on any Business Day occurring after the time of the initial Borrowing hereunder, voluntarily reduce the amount of the Commitment Amount; provided, however, that all such reductions shall require at least three Business Days' prior notice to the Agent and be permanent, and any partial reduction of the Commitment Amount shall be in a minimum amount of $25,000,000 and in an integral multiple of $5,000,000. SECTION 2.4 Base Rate Loans and Eurodollar Loans. Subject to the terms and conditions set forth in Article V, each Loan shall be either a Eurodollar Loan or a Base Rate Loan as the Borrower may request, it being understood that Loans made to the Borrower on any date may be either Eurodollar Loans or Base Rate Loans or a combination thereof. As to any Eurodollar Loan, each Lender may, if it so elects, fulfill its commitment to make such Eurodollar Loan by causing its Eurodollar Office to make such Eurodollar Loan; provided, however, that in such event the obligation of the Borrower to repay such Eurodollar Loan nevertheless shall be to such Lender and shall be deemed to be held by such Lender for the account of such Eurodollar Office. SECTION 2.5 Borrowing Procedures for Loans. The Borrower shall give the Agent prior written or telegraphic notice pursuant to a Borrowing Request (in substantially the form of Exhibit 2.5 hereto) of each proposed Borrowing or continuation, and as to whether such Borrowing or continuation is to be of Base Rate Loans or Eurodollar Loans, as follows: SECTION 2.5.1 Domestic Loans. The Agent shall receive written or telegraphic notice from the Borrower on or before 2:00 p.m. New York time one Business Day prior to the date of such Borrowing and amount of such Borrowing (which shall be in a minimum amount of $10,000,000 and an integral multiple of $1,000,000), and the Agent shall advise each Lender thereof promptly thereafter. Not later than 10:00 a.m., New York time, on the date specified in such notice for such Borrowing, each Lender shall provide to the Agent at the Payment Office, same day or immediately available funds covering such Lender's Percentage of the requested Base Rate Loan. Upon fulfillment of the applicable conditions set forth in Article V with respect to such Base Rate Loan, the Agent shall make available to the Borrower the proceeds of each Base Rate Loan (to the extent received from the Lenders) by wire transfer of such proceeds to such account(s) as the Borrower shall have specified in the Borrowing Request. SECTION 2.5.2 Eurodollar Loans. The Agent shall receive written or telegraphic notice pursuant to a Borrowing Request from the Borrower on or before 10:00 a.m. New York time, at least three (3) Business Days prior to the date requested for each proposed Borrowing or continuation of a Eurodollar Loan, of the date of such Borrowing or continuation, as the case may be, the amount of such Borrowing or continuation, as the case may be (which shall be in a minimum amount of $10,000,000 and an integral multiple of $1,000,000), and the duration of the initial Euro- 23 30 dollar Interest Period with respect thereto, and the Agent shall advise each Lender thereof promptly thereafter. Not later than 10:00 a.m., New York time, on the date specified in such notice for such Borrowing, each Lender shall provide to the Agent at the Payment Office, same day or immediately available funds covering such Lender's Percentage of the requested Eurodollar Loan. Upon fulfillment of the applicable conditions set forth in Article V with respect to such Eurodollar Loan, the Agent shall make available to the Borrower the proceeds of each Eurodollar Loan (to the extent received from the Lenders) by wire transfer of such proceeds to such account(s) as the Borrower shall have specified in the Borrowing Request. SECTION 2.6 Continuation and Conversion Elections. By delivering a Continuation/Conversion Notice to the Agent on or before 10:00 a.m., New York time, on a Business Day, the Borrower may from time to time irrevocably elect, on not less than three nor more than five Business Days' notice that all, or any portion in an aggregate minimum amount of $10,000,000 and an integral multiple of $1,000,000 of any Borrowings be, (i) in the case of Base Rate Loans, converted into Eurodollar Loans, or (ii) in the case of Eurodollar Loans, be converted into a Base Rate Loan or continued as a Eurodollar Loan of such Type (in the absence of delivery of a Continuation/Conversion Notice with respect to any Eurodollar Loan at least three Business Days before the last day of the then current Interest Period with respect thereto, such Eurodollar Loan shall, on such last day, automatically convert to a Base Rate Loan); provided, however, that (i) each such conversion or continuation shall be pro rated among the applicable outstanding Loans of all Lenders, and (ii) no portion of the outstanding principal amount of any Loans may be continued as, or be converted into, Eurodollar Loans when any Default has occurred and is continuing. SECTION 2.7 Funding. Each Lender may, if it so elects, fulfill its obligation to make, continue or convert Eurodollar Loans hereunder by causing one of its foreign branches or Affiliates (or an international banking facility created by such Lender) to make or maintain such Eurodollar Loan; provided, however, that such Eurodollar Loan shall nonetheless be deemed to have been made and to be held by such Lender, and the obligation of the Borrower to repay such Eurodollar Loan shall nevertheless be to such Lender for the account of such foreign branch, Affiliate or international banking facility. In addition, the Borrower hereby consents and agrees that, for purposes of any determination to be made for purposes of Sections 4.1, 4.2, 4.3 or 4.4, it shall be conclusively assumed that each Lender elected to fund all Eurodollar Loans by purchasing, as the case may be, Dollar deposits in its Eurodollar Office's interbank eurodollar market. SECTION 2.8 Notes. Each Lender's Revolving Loans shall be evidenced by a Revolving Note, payable to the order of such Lender in a maximum principal amount equal to such Lender's Percentage of the original applicable Commitment Amount. Each Lender's Competitive Bid Loans shall be evidenced by a Competitive Bid Note, each payable to the order of such Lender in a maximum principal amount of $300,000,000. The Borrower hereby irrevocably authorizes each Lender to make (or cause to be made) appropriate notations on the grid attached to such Lender's Notes (or on any continuation of such grid), which notations, if made, shall evidence, inter alia, the date of, the outstanding principal of, and the interest rate and Interest Period applicable to the Revolving Loans or Competitive Bid Loans evidenced thereby. Such notations shall be conclusive 24 31 and binding on the Borrower absent manifest error; provided, however, that the failure of any Lender to make any such notations shall not limit or otherwise affect any Obligations of the Borrower. ARTICLE III REPAYMENTS, PREPAYMENTS, INTEREST AND FEES SECTION 3.1 Repayments and Prepayments. The Borrower shall repay in full the unpaid principal amount of each Loan upon the Stated Maturity Date or of each Competitive Bid Loan on the last day of its applicable Interest Period. Prior thereto, the Borrower (a) may, from time to time on any Business Day, make a voluntary prepayment, in whole or in part, of the outstanding principal amount of any Loans; provided, however, that (i) any such prepayment shall be applied to the Lenders among Loans having the same Type and, if applicable, having the same Interest Period; (ii) no such prepayment of any Competitive Bid Loan may be made on any day other than the last day of the Interest Period for such Loan; (iii) all such voluntary prepayments shall require at least three Business Days' prior written notice to the Agent; and (iv) all such voluntary partial prepayments shall be in an minimum amount of $10,000,000 and an integral multiple of $5,000,000; and (b) shall, immediately upon any acceleration of the Stated Maturity Date of any Loans pursuant to Section 8.2 or Section 8.3, repay all Loans, unless, pursuant to Section 8.3, only a portion of all Loans is so accelerated. Each prepayment of Loans shall be applied, to the extent of such prepayment, in the inverse order of maturity. Each prepayment of any Loans made pursuant to this Section shall be without premium or penalty, except as may be required by Section 4.4. No voluntary prepayment of principal of any Revolving Loans shall cause a reduction in the Commitment Amount. SECTION 3.2 Interest Provisions. Interest on the outstanding principal amount of Loans shall accrue and be payable in accordance with this Section 3.2. SECTION 3.2.1 Rates. Pursuant to an appropriately delivered Borrowing Request or Continuation/Conversion Notice, the Borrower may elect that Loans comprising a Borrowing accrue interest at a rate per annum: (a) on that portion maintained from time to time as a Base Rate Loan, equal to the sum of the Base Rate from time to time in effect; and (b) on that portion maintained as a Eurodollar Loan, during each Interest Period applicable thereto, equal to the sum of the Eurodollar Rate for such Interest Period plus the Applicable Margin. All Eurodollar Borrowings shall bear interest from and including the first day of the applicable Interest Period to (but not including) the last day of such Interest Period at the interest rate determined as applicable to such Eurodollar Borrowing. 25 32 SECTION 3.2.2 Post-Maturity Rates. After the date any principal amount of any Loan is due and payable (whether on the Stated Maturity Date, upon acceleration or otherwise), or after any other monetary Obligation of the Borrower shall have become due and payable, the Borrower shall pay, but only to the extent permitted by law, interest (after as well as before judgment) on such amounts at a rate per annum equal to the Base Rate plus the Default Margin. SECTION 3.2.3 Payment Dates. Interest accrued on each Borrowing shall be payable, without duplication on the following dates (each a "Payment Date"): (a) on the Stated Maturity Date therefor; (b) on the date of any payment or prepayment, in whole or in part, of principal outstanding on such Loan on the amount of such principal prepaid or repaid; (c) with respect to Base Rate Loans, on each Quarterly Payment Date occurring after the Effective Date; (d) with respect to Eurodollar Borrowings, on the last day of each applicable Interest Period (and, if such Interest Period shall exceed 90 days, on the 90th day of such Interest Period); (e) with respect to any portion of Base Rate Loans converted into Eurodollar Loans on a day when interest would not otherwise have been payable pursuant to clause (c), on the date of such conversion; and (f) on that portion of any Borrowings the Stated Maturity Date of which is accelerated pursuant to Section 8.2 or Section 8.3, immediately upon such acceleration; and (g) with respect to Competitive Bid Loans, as otherwise provided by the relevant Competitive Bid Quote Request. Interest accrued on Borrowings or other monetary Obligations arising under this Agreement or any other Loan Document after the date such amount is due and payable (whether on the Stated Maturity Date, upon acceleration or otherwise) shall be payable upon demand.

The Borrower agrees to pay to the Agent for the account of each Lender, a facility fee in an amount equal to the product of the Applicable Facility Fee Rate times such Lender's Percentage times the Commitment Amount as it may be reduced from time to time, pursuant to reductions under Section 2.3. SECTION 3.3.2 Agent's Fee. The Borrower agrees to pay to the Agent for its own account, all fees (including any fees pursuant to Section 2.2.8) pursuant to that certain fee letter agreement dated December 24, 1997, between the Borrower and the Agent, as amended from time to time (the "Agent Fee Letter"). SECTION 3.3.3 Payment Office. The Borrower shall make all payments to the Agent at the Payment Office. 26 33 ARTICLE IV CERTAIN EURODOLLAR AND OTHER PROVISIONS SECTION 4.1 Eurodollar Lending Unlawful. If any Lender shall determine (which determination shall, upon notice thereof to the Borrower and the Lenders, be conclusive and binding on the Borrower) that the introduction of or any change in or in the interpretation of any law makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for such Lender to make, continue or maintain any Borrowing as, or to convert any Borrowing into, a Eurodollar Borrowing, the obligations of such Lender to make, continue, maintain or convert any such Borrowings shall, upon such determination, forthwith be suspended until such Lender shall notify the Agent that the circumstances causing such suspension no longer exist, and all Eurodollar Borrowings shall automatically convert into Base Rate Loans at the end of the then current Interest Periods with respect thereto or sooner, if required by such law or assertion; provided, however, that the obligation of such Lender to make, continue, maintain or convert any such Eurodollar Borrowings shall remain unaffected if such Lender can designate a different Eurodollar Office for the making, continuance, maintenance or conversion of Eurodollar Borrowings and such designation will not, in the sole discretion of such Lender, be otherwise disadvantageous to such Lender. SECTION 4.2 Deposits Unavailable or Eurodollar Interest Rate Unascertainable. If the Agent shall have determined that, by reason of circumstances affecting the Agent's relevant market, adequate means do not exist for ascertaining the interest rate applicable hereunder to Eurodollar Borrowings, then, upon notice from the Agent to the Borrower and the Lenders, the obligations of all Lenders under Section 2.6 and Section 2.8 to make or continue any Borrowings as, or to convert any Borrowings into, Eurodollar Borrowings shall forthwith be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist. SECTION 4.3 Increased Eurodollar Borrowing Costs, etc. The Borrower agrees to reimburse each Lender for any increase in the cost to such Lender of, or any reduction in the amount of any sum receivable by such Lender in respect of, making, continuing or maintaining (or of its obligation to make, continue or maintain) any Borrowings as, or of converting (or of its obligation to convert) any Borrowings into, Eurodollar Borrowings. Such Lender shall promptly notify the Agent and the Borrower in writing of the occurrence of any such event, such notice to state, in reasonable detail, the reasons therefor and the additional amount required fully to compensate such Lender for such increased cost or reduced amount; provided, however, that such Lender shall designate a different Eurodollar Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole discretion of such Lender, be otherwise disadvantageous to such Lender. Such additional amounts shall be payable by the Borrower directly to such Lender within fifteen days of its receipt of such notice, and such notice shall be rebuttable presumptive evidence of the amount payable by the Borrower. SECTION 4.4 Funding Losses. In the event any Lender shall incur any loss or expense (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or 27 34 other funds acquired by such Lender to make, continue or maintain any portion of the principal amount of any Borrowing as, or to convert any portion of the principal amount of any Borrowing into, a Eurodollar Borrowing) as a result of (a) any conversion or repayment or prepayment of the principal amount of any Eurodollar Borrowings on a date other than the scheduled last day of the Interest Period applicable thereto, whether pursuant to Section 3.1 or otherwise, (b) any Borrowings not being made as Eurodollar Borrowings in accordance with the Borrowing Request or Competitive Bid Quote Request, as the case may be, therefor, or (c) any Borrowings not being continued as, or converted into, Eurodollar Borrowings in accordance with the Continuation/Conversion Notice therefor, then, upon the written notice of such Lender to the Borrower (with a copy to the Agent), the Borrower shall, within fifteen days of its receipt thereof, pay directly to such Lender such amount as will (in the reasonable determination of such Lender) reimburse such Lender for such loss or expense. Such written notice (which shall include calculations in reasonable detail) shall be rebuttable presumptive evidence of the amount payable by the Borrower. SECTION 4.5 Increased Capital Costs. If any change in, or the introduction, adoption, effectiveness, interpretation, reinterpretation or phase-in of, any law or regulation, directive, guideline, decision or request (whether or not having the force of law) of any court, central bank, regulator or other governmental authority affects or would affect the amount of capital required or expected to be maintained by any Lender or any Person controlling such Lender, and such Lender determines (in its sole discretion) that the rate of return on its or such controlling Person's capital as a consequence of its Commitments or the Borrowings made by such Lender is reduced to a level below that which such Lender or such controlling Person could have achieved but for the occurrence of any such circumstance, then, in any such case upon notice from time to time by such Lender to the Borrower, the Borrower shall pay directly to such Lender, within fifteen days, additional amounts sufficient to compensate such Lender or such controlling Person for such reduction in rate of return; provided, however, that such Lender shall designate a different Domestic or Eurodollar Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole discretion of such Lender, be otherwise disadvantageous to such Lender. A statement of such Lender as to any such additional amount or amounts (including calculations thereof in reasonable detail) shall be rebuttable presumptive evidence of the amount payable by the Borrower. In determining such amount, such Lender may use any reasonable method of averaging and attribution that it (in its sole discretion) shall deem applicable. SECTION 4.6 Taxes. All payments by the Borrower of principal of, and interest on, the Borrowings and all other amounts payable hereunder shall be made free and clear of and without deduction for any present or future income, excise, stamp or franchise taxes and other taxes, fees, duties, withholdings or other charges of any nature whatsoever imposed by any taxing authority, but excluding franchise taxes and taxes imposed on or measured by any Lender's net income or receipts (such non-excluded items being called "Taxes"). In the event that any withholding or deduction from any payment to be made by the Borrower hereunder is required in respect of any Taxes pursuant to any applicable law, rule or regulation, then the Borrower will, within fifteen days (a) pay directly to the relevant authority the full amount required to be so withheld or deducted; (b) promptly forward to the Agent an official receipt or other documentation satisfactory to the Agent evidencing 28 35 such payment to such authority; and (c) pay to the Agent for the account of the Lenders such additional amount or amounts as is necessary to ensure that the net amount actually received by each Lender will equal the full amount such Lender would have received had no such withholding or deduction been required. If any Taxes are directly asserted against the Agent or any Lender with respect to any payment received by the Agent or such Lender hereunder, the Agent or such Lender may pay such Taxes and the Borrower will promptly pay such additional amounts (including any penalties, interest or expenses) as is necessary in order that the net amount received by such person after the payment of such Taxes (including any Taxes on such additional amount) shall equal the amount such person would have received had not such Taxes been asserted; provided that the Borrower will not be obligated to pay such additional amounts to the Agent or such Lender to the extent that such additional amounts shall have been incurred as a consequence of the Agent's or such Lender's gross negligence or willful misconduct, as the case may be. If the Borrower fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to the Agent, for the account of the respective Lenders, the required receipts or other required documentary evidence, the Borrower shall indemnify the Lenders for any incremental Taxes, interest or penalties that may become payable by any Lender as a result of any such failure. For purposes of this Section 4.6, a distribution hereunder by the Agent or any Lender to or for the account of any Lender shall be deemed a payment by the Borrower. Each Lender that is organized under the laws of a jurisdiction other than the United States shall, prior to the due date of any payments under the Notes, execute and deliver to the Borrower and the Agent, on or about the first scheduled Payment Date in each Fiscal Year, one or more (as the Borrower or the Agent may reasonably request) United States Internal Revenue Service Forms 4224 or Forms 1001 or such other forms or documents (or successor forms or documents), appropriately completed, as may be applicable to establish the extent, if any, to which a payment to such Lender is exempt from withholding or deduction of Taxes, and shall (but only so long as such Lender remains lawfully able to do so) deliver to the Borrower and the Agent additional copies of such forms on or before the date that such forms expire or become obsolete or after the occurrence of an event requiring a change in the most recent form so delivered by it and such amendments thereto as may be reasonably requested by the Borrower or the Agent, in each case certifying that such Lender is entitled to benefits under an income tax treaty to which the United States is a party which reduces the rate of withholding tax on payments of interest or fees or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States. If the form provided by a Lender at the time such Lender first becomes a party to this Agreement indicates a United States withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from the definition of "Taxes". For any period with respect to which a Lender has failed to provide the Borrower and the Agent with the forms required pursuant to this paragraph, if any (other than if such failure is due to a change in treaty, law or regulation occurring subsequent to the date on which a form originally was required to be provided), such Lender shall not be entitled to indemnification under this Section 4.6 with respect to Taxes imposed 29 36 by the United States which Taxes would not have been imposed but for such failure to provide such form; provided, however, that should a Lender, which is otherwise exempt from or subject to a reduced rate of withholding tax, become subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as the Lender shall reasonably request to assist the Lender to recover such Taxes. If the Borrower is required to pay additional amounts to or for the account of any Lender pursuant to this Section 4.6, then such Lender will change the jurisdiction of its applicable Eurodollar or Domestic Office so as to eliminate or reduce any such additional payment which may thereafter accrue if such change, in the sole discretion of such Lender, is not otherwise disadvantageous to such Lender. No Lender shall be entitled to receive any greater payment under this Section 4.6 as a result of the designation by such Lender of a different applicable Eurodollar or Domestic Office after the date hereof, unless such designation is made with the Borrower's prior written consent or by reason of the provisions of Sections 4.1, 4.3 or 4.5 requiring such Lender to designate a different applicable Eurodollar or Domestic Office under certain circumstances or at a time when the circumstances giving rise to such greater payment did not exist. SECTION 4.7 Special Fees in Respect of Reserve Requirements. With respect to Eurodollar Borrowings, the Borrower agrees to pay to each Lender on appropriate Payment Dates, as additional interest, such amounts as will compensate such Lender for any cost to such Lender, from time to time, of any reserve, special deposit, special assessment or similar capital requirements against assets of, deposits with or for the account of, or credit extended by, such Lender which are imposed on, or deemed applicable by, such Lender, from time to time, under or pursuant to (i) any Law, treaty, regulation or directive now or hereafter in effect (including, without limitation, Regulation D of the Board of Governors of the Federal Reserve System but excluding any reserve requirement included in the definition of Eurodollar Rate in Section 1.1), (ii) any interpretation or application thereof by any governmental authority, agency or instrumentality charged with the administration thereof or by any court, central bank or other fiscal, monetary or other authority having jurisdiction over the Eurodollar Borrowings or the office of such Lender where its Eurodollar Borrowings are lodged, or (iii) any requirement imposed or requested by any court, governmental authority, agency or instrumentality or central bank, fiscal, monetary or other authority, whether or not having the force of law. A written notice as to the amount of any such cost or any change therein (including calculations, in reasonable detail, showing how such Lender computed such cost or change) shall be promptly furnished by such Lender to the Borrower and shall be rebuttable presumptive evidence of such cost or change. The Borrower will not be responsible for paying any amounts pursuant to this Section 4.7 accruing prior to 180 days prior to the receipt by the Borrower of the written notice referred to in the preceding sentence. Within fifteen (15) days after such certificate is furnished to the Borrower, the Borrower will pay directly to such Lender such additional amount or amounts as will compensate such Lender for such cost or change. SECTION 4.8 Payments, Computations, etc. Unless otherwise expressly provided, all payments by the Borrower pursuant to this Agreement, the Notes or any other Loan Document shall be made by the Borrower to the Agent for the pro rata account of the Lenders entitled to receive such 30 37 payment. All such payments required to be made to the Agent shall be made, without setoff, deduction or counterclaim, not later than 11:00 a.m., New York time, on the date due, in same day or immediately available funds, to such account as the Agent shall specify from time to time by notice to the Borrower. Funds received after that time shall be deemed to have been received by the Agent on the next succeeding Business Day. The Agent shall promptly remit in same day funds to each Lender its share, if any, of such payments received by the Agent for the account of such Lender. All interest and fees shall be computed on the basis of the actual number of days (including the first day but excluding the last day) occurring during the period for which such interest or fee is payable over a year comprised of 360 days (or, in the case of interest on a Base Rate Loan, 365 days or, if appropriate, 366 days). Whenever any payment to be made shall otherwise be due on a day which is not a Business Day, such payment shall (except as otherwise required by clause (c) of the definition of the term "Interest Period" with respect to Eurodollar Loans) be made on the next succeeding Business Day and such extension of time shall be included in computing interest and fees, if any, in connection with such payment. SECTION 4.9 Sharing of Payments. If any Lender shall obtain any payment or other recovery (whether voluntary, involuntary, by application of setoff or otherwise) on account of any Loan (other than pursuant to the terms of Sections 4.3, 4.4 and 4.5) in excess of its pro rata share of payments then or therewith obtained by all Lenders, such Lender shall purchase from the other Lenders such participations in Loans made by them as shall be necessary to cause such purchasing Lender to share the excess payment or other recovery ratably with each of them; provided, however, that if all or any portion of the excess payment or other recovery is thereafter recovered from such purchasing Lender, the purchase shall be rescinded and each Lender which has sold a participation to the purchasing Lender shall repay to the purchasing Lender the purchase price to the ratable extent of such recovery together with an amount equal to such selling Lender's ratable share (according to the proportion of (a) the amount of such selling Lender's required repayment to the purchasing Lender to (b) 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 4.9 may, to the fullest extent permitted by law, exercise all its rights of payment with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a set off to which this Section 4.9 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders entitled under this Section to share in the benefits of any recovery on such secured claim. SECTION 4.10 Use of Proceeds. The Borrower shall apply the proceeds of each Borrowing in accordance with the fourth recital; without limiting the foregoing, no proceeds of any Borrowing will be used to acquire any equity security of a class which is registered pursuant to Section 12 of the Securities Exchange Act of 1934 or any "margin stock", as defined in F.R.S. Board Regulation U. 31 38 SECTION 4.11 Replacement of Lender on Account of Increased Costs, Eurodollar Lending Unlawful, Reserve Requirements, Taxes, Certain Dissents, etc. If any Lender shall claim the inability to make or maintain Eurodollar Borrowings pursuant to Section 4.1 above, if any Lender is owed increased costs under Section 4.5 above, if any payment to any Lender by the Borrower is subject to any withholding tax pursuant to Section 4.6 above, or if any Lender is owed any cost or expense pursuant to Section 4.7 above, the Borrower shall have the right, if no Event of Default or Unmatured Event of Default then exists, to replace such Lender with another bank or financial institution provided that (i) if it is not a Lender or an Affiliate thereof, such bank or financial institution shall be reasonably acceptable to the Agent and (ii) such bank or financial institution shall unconditionally purchase, in accordance with Section 10.11 hereof, all of such Lender's rights and obligations under this Agreement and the Notes and the appropriate pro rata share of such Lender's Notes and Commitments, without recourse or expense to, or warranty by, such Lender being replaced for a purchase price equal to the aggregate outstanding principal amount of the Notes payable to such Lender, plus any accrued but unpaid interest on such Notes plus accrued but unpaid fees in respect of such Lender's Borrowings and Percentage of the Commitments hereunder to the date of such purchase on a date therein specified. The Borrower shall be obligated to pay, simultaneously with such purchase and sale, the increased costs, amounts, expenses and taxes under Sections 4.1, 4.5, 4.6, and 4.7 above, all breakage fees payable under Section 4.4 and all other costs, fees and expenses payable to such Lender hereunder and under the Loan Documents, to the date of such purchase as well as all other Obligations due and payable to or for the benefit of such Lender; provided, that if such bank or financial institution fails to purchase such rights and obligations, the Borrower shall continue to be obligated to pay the increased costs, amounts, expenses and taxes under Sections 4.1, 4.5, 4.6, and 4.7 above to such Lender. SECTION 4.12 Maximum Interest. It is the intention of the parties hereto to conform strictly to applicable usury laws and, anything herein to the contrary notwithstanding, the obligations of the Borrower to each Lender under this Agreement shall be subject to the limitation that payments of interest shall not be required to the extent that receipt thereof would be contrary to provisions of law applicable to such Lender limiting rates of interest which may be charged or collected by such Lender. Accordingly, if the transactions contemplated hereby would be usurious under applicable law (including the Federal and state laws of the United States of America, or of any other jurisdiction whose laws may be mandatorily applicable) with respect to a Lender then, in that event, notwithstanding anything to the contrary in this Agreement, it is agreed as follows: (a) the provisions of this Section 4.12 shall govern and control; (b) the aggregate of all consideration which constitutes interest under applicable law that is contracted for, charged or received under this Agreement, or under any of the other aforesaid agreements or otherwise in connection with this Agreement by such Lender shall under no circumstances exceed the maximum amount of interest allowed by applicable law (such maximum lawful interest rate, if any, with respect to such Lender herein called the "Highest Lawful Rate"), and any excess shall be credited to the Borrower by such Lender (or, if such consideration shall have been paid in full, such excess refunded to the Borrower); (c) all sums paid, or agreed to be paid, to such Lender for the use, forbearance and detention of the Indebtedness of the Borrower to such Lender hereunder shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of such Indebtedness until payment in full 32 39 so that the actual rate of interest is uniform throughout the full term thereof; and (d) if at any time the interest provided pursuant to Section 4.1 together with any other fees payable pursuant to this Agreement and deemed interest under applicable law, exceeds that amount which would have accrued at the Highest Lawful Rate, the amount of interest and any such fees to accrue to such Lender pursuant to this Agreement shall be limited, notwithstanding anything to the contrary in this Agreement to that amount which would have accrued at the Highest Lawful Rate, but any subsequent reductions, as applicable, shall not reduce the interest to accrue to such Lender pursuant to this Agreement below the Highest Lawful Rate until the total amount of interest accrued pursuant to this Agreement and such fees deemed to be interest equals the amount of interest which would have accrued to such Lender if a varying rate per annum equal to the interest provided pursuant to Section 3.2 had at all times been in effect, plus the amount of fees which would have been received but for the effect of this Section 4.12. For purposes of Article 5069-1.04, Vernon's Texas Civil Statutes, as amended, to the extent, if any, applicable to a Lender, the Borrower agrees that the Highest Lawful Rate shall be the "indicated (weekly) rate ceiling" as defined in said Article, provided that such Lender may also rely, to the extent permitted by applicable laws, on alternative maximum rates of interest under other laws applicable to such Lender if greater. Tex. Rev. Civ. Stat. Ann. Art. 5069, Ch. 15 (which regulates certain revolving credit loan accounts and revolving tri-party accounts) shall not apply to this Agreement or the Notes. ARTICLE V CONDITIONS TO BORROWING SECTION 5.1 Initial Borrowing.

Each Lender acknowledges that none of the Managing Agents and the Co-Agents have any duties or obligations under this Agreement in connection with their capacity as a Managing Agent or a Co-Agent, as the case may be. Each Lender hereby indemnifies (which indemnity shall survive any termination of this Agreement) each of the Agent, the Managing Agents and the Co-Agents, pro rata according to such Lender's Percentage, whether or not related to any singular, joint or concurrent negligence of the Agent, the Managing Agents and the Co-Agents, from and against any and all liabilities, obligations, losses, damages, claims, costs or expenses of any kind or nature whatsoever which may at any time be imposed on, incurred by, or asserted against, the Agent, any Managing Agent or any Co-Agent in any way relating to or arising out of this Agreement, the Notes and any other Loan Document, including reasonable attorneys' fees, and as to which the Agent, such Managing Agent or such Co- Agent is not reimbursed by the Borrower; provided, however, that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, claims, costs or expenses which are determined by a court of competent jurisdiction in a final proceeding to have resulted solely from the Agent's, such Managing Agent's or such Co- Agent's gross negligence or wilful misconduct. None of the Agent, the Managing Agents and the Co-Agents shall be required to take any action hereunder, under the Notes or under any other Loan Document, or to prosecute or defend any suit in respect of this Agreement, the Notes or any other Loan Document, unless it is indemnified 45 52 hereunder to its satisfaction. If any indemnity in favor of the Agent, any Managing Agent or any Co-Agent shall be or become inadequate, in the Agent's, such Managing Agent's or such Co-Agent's determination, as the case may be, the Agent, such Managing Agent or such Co-Agent, as the case may be, may call for additional indemnification from the Lenders and cease to do the acts indemnified against hereunder until such additional indemnity is given. Notwithstanding any provision to the contrary contained elsewhere in this Agreement or in any other Loan Document, none of the Agent, the Managing Agents and the Co-Agents shall have any duties or responsibilities, except as expressly set forth herein, nor shall any of the Agent, the Managing Agents and the Co-Agents have or be deemed to have any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against any of the Agent, the Managing Agents and the Co-Agents.

If and to the extent that such Lender shall not have made such amount available to the Agent, such Lender and the Borrower severally agree to repay the Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date the Agent made such amount available to the Borrower to the date such amount is repaid to the Agent, at the Federal Funds Rate. SECTION 9.3 Exculpation. None of the Agent, the Managing Agents, the Co-Agents and their respective directors, officers, employees or agents shall be liable to any Lender for any action taken or omitted to be taken by it under this Agreement or any other Loan Document, or in connection herewith or therewith, except for its own wilful misconduct or gross negligence, nor responsible for any recitals or warranties herein or therein, nor for the effectiveness, enforceability, validity or due execution of this Agreement or any other Loan Document, nor to make any inquiry respecting the performance by the Borrower of its obligations hereunder or under any other Loan Document. Any such inquiry which may be made by the Agent, any Managing Agent or any Co-Agent shall not obligate it to make any further inquiry or to take any action. Each of the Agent, the Managing Agents and the Co-Agents shall be entitled to rely upon advice of counsel concerning legal matters and upon any notice, consent, certificate, statement or writing which the Agent, such Managing Agent or such Co-Agent believes to be genuine and to have been presented by a proper Person. SECTION 9.4 Successor. Any of the Agent, the Managing Agents and the Co-Agents may resign as such at any time upon at least 30 days' prior notice to the Borrower and all Lenders. If the Agent at any time shall resign, the Required Lenders may appoint another Lender as the successor 46 53 Agent which shall thereupon become the Agent hereunder. If no successor Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Agent's giving notice of resignation, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be one of the Lenders or a commercial banking institution organized under the laws of the U.S. (or any State thereof) or a U.S. branch or agency of a commercial banking institution, and having a combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as the Agent hereunder by a successor Agent, such successor Agent shall be entitled to receive from the retiring Agent such documents of transfer and assignment as such successor Agent may reasonably request, and shall thereupon succeed to and become vested with all rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under this Agreement. After a retiring Agent's, Managing Agent's or Co-Agent's resignation hereunder as Agent, Managing Agent or Co-Agent, the provisions of (a)this Article IX shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Agent under this Agreement, and Section 10.4 (and, with respect to the Agent, Section 10.3) shall continue to inure to its benefit. SECTION 9.5 Loans by the Agents. Each of the Agent, the Managing Agents and the Co-Agents shall have the same rights and powers with respect to (x) the Loans made by it or any of its Affiliates, and (y) the Notes held by it or any of its Affiliates as any other Lender and may exercise the same as if it were not the Agent, a Managing Agent or a Co-Agent, as the case may be. Each of the Agent, the Managing Agents and the Co-Agents 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 Affiliate of the Borrower as if it were not the Agent, a Managing Agent or a Co-Agent hereunder, as the case may be. SECTION 9.6 Credit Decisions. Each Lender acknowledges that it has made its own credit decision to extend its Commitments hereunder (i) independently of each of the Agent, the Managing Agents, the Co-Agents and each other Lender, and (ii) based on such Lender's review of the financial information of the Borrower, this Agreement, the other Loan Documents (the terms and provisions of which being satisfactory to such Lender) and such other documents, information and investigations as such Lender has deemed appropriate. Each Lender also acknowledges that it will continue to make its own credit decisions as to exercising or not exercising from time to time any rights and privileges available to it under this Agreement or any other Loan Document (i) independently of each of the Agent, the Managing Agents, the Co-Agents and each other Lender, and (ii) based on such other documents, information and investigations as it shall deem appropriate at any time. SECTION 9.7 Copies, etc. The Agent shall give prompt notice to each Lender of each notice or request required or permitted to be given to the Agent by the Borrower pursuant to the terms of this Agreement (unless concurrently delivered to the Lenders by the Borrower).

No notice to or demand on the Borrower in any case shall entitle it to any notice or demand in similar or other circumstances. No waiver or approval by the Agent, any Lender or the holder of any Note under this Agreement or any other Loan Document shall, except as may be otherwise stated in such waiver or approval, be applicable to subsequent transactions. No waiver or approval hereunder shall require any similar or dissimilar waiver or approval thereafter to be granted hereunder. SECTION 10.2 Notices.

From and after the date that the Agent accepts such Lender Assignment Agreement, (x) the Assignee Lender thereunder shall be deemed automatically to have become a party hereto and to the extent that rights and obligations hereunder have been assigned and delegated to such Assignee Lender in connection with such Lender Assignment Agreement, shall have the rights and obligations of a Lender hereunder and under the other Loan Documents, and (y) the assignor Lender, to the extent that rights and obligations hereunder have been assigned and delegated by it in connection with such Lender Assignment Agreement, shall be released from its obligations hereunder and under the other Loan Documents. Within five Business Days after its receipt of notice that the Agent has received an executed Lender Assignment Agreement, the Borrower shall execute and deliver to the Agent (for delivery to the relevant Assignee Lender) new Notes evidencing such Assignee Lender's assigned Loans and Commitments and, if the assignor Lender has retained Loans and Commitments hereunder, replacement Notes in the principal amount of the Loans and Commitments retained by the assignor Lender hereunder (such Notes to be in exchange for, but not in payment of, those Notes then held by such assignor Lender). Each such Note shall be dated the date of the predecessor Notes. The assignor Lender shall mark the predecessor Notes "exchanged" and deliver them to the Borrower. Accrued interest on that part of the predecessor Notes evidenced by the new Notes, and accrued fees, shall be paid as provided in the Lender Assignment Agreement. Accrued interest on that part of the predecessor Notes evidenced by the replacement Notes shall be paid to the assignor Lender. Accrued interest and accrued fees shall be paid at the same time or times provided in the predecessor Notes and in this Agreement. Such assignor Lender or such Assignee Lender must also pay a processing fee to the Agent upon delivery of any Lender Assignment Agreement in the amount of $2,000. Any attempted assignment and delegation not made in accordance with this Section 10.11.1 shall be null and void. 51 58 SECTION 10.11.2 Participations. Any Lender may at any time sell to one or more commercial banks or other Persons (each of such commercial banks and other Persons being herein called a "Participant") participating interests in any of the Loans, Commitments, or other interests of such Lender hereunder; provided, however, that (a) no participation contemplated in this Section 10.11 shall relieve such Lender from its Commitments or its other obligations hereunder or under any other Loan Document, (b) such Lender shall remain solely responsible for the performance of its Commitments and such other obligations, (c) the Borrower and the Agent shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement and each of the other Loan Documents, (d) no Participant, unless such Participant is an Affiliate of such Lender, or is itself a Lender, shall be entitled to require such Lender to take or refrain from taking any action hereunder or under any other Loan Document, except that such Lender may agree with any Participant that such Lender will not, without such Participant's consent, take any actions of the type described in clause (b) or (c) of Section 10.1, and (e) the Borrower shall not be required to pay any amount under Section 4.6 that is greater than the amount which it would have been required to pay had no participating interest been sold. The Borrower acknowledges and agrees that each Participant, for purposes of Sections 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9 and 10.4, shall be considered a Lender; provided that this sentence shall not obligate Borrower to pay more under such Sections that it would be obligated to pay had no such participation been granted. SECTION 10.12 Other Transactions. Nothing contained herein shall preclude the Agent or any other Lender from engaging in any transaction, in addition to those contemplated by this Agreement or any other Loan Document, with the Borrower or any of its Affiliates in which the Borrower or such Affiliate is not restricted hereby from engaging with any other Person.

Lenders hereby sell, assign, transfer and convey, and Lenders hereby purchase and accept so much of the Prior Indebtedness and all of the rights, titles, benefits, interests, privileges, claims, liens, security interests, and obligations existing and to exist (collectively the "Interests") such that each Lender's Percentage of the outstanding loans and commitments under the Original Credit Agreement as amended and restated by this Agreement shall be as set forth in Schedule IIA as of the Effective Date. The foregoing assignment, transfer and conveyance are without recourse to the Lenders and without any warranties whatsoever as to title, enforceability, collectibility, documentation or freedom from liens or encumbrances, in whole or in part, other than the warranty by each Lender that it has not sold, transferred, conveyed or encumbered such Interests. If as a result thereof, a Lender's Percentage of the outstanding Loans under this Agreement is less than its outstanding loans under the Original Credit Agreement on the Effective Date, the difference set forth in the last column of Schedule IIB shall be remitted to such Lender by the Agent upon receipt of funds from the other Lenders shown in the last column of Schedule IIB on the Effective Date. Each Lender so acquiring a part of such outstanding loans assumes its Percentage of the outstanding Loans, Commitments, 52 59 rights, titles, interests, privileges, claims, liens, security interests, benefits and obligations under this Agreement and the other Loan Documents and any Lender so acquiring an interest in such outstanding Loans may be paid a cost of funds with respect thereto as mutually agreed between the Borrower and such Lender. Lenders are proportionately released from the obligations assumed by Lenders so acquiring such obligations and, to that extent, the Lenders so released shall have no further obligation under the Original Credit Agreement, as amended and restated hereby. The Borrower hereby represents and warrants that it has no defenses, offsets or counterclaims to the Prior Indebtedness or its obligations or rights under this Agreement, including, without limitation, the Interests being assigned pursuant to this Section 10.13. The promissory notes evidencing the Prior Indebtedness shall be appropriately endorsed and delivered by the holders thereof to the Agent and retained by the Agent until the Obligations shall have been paid in full, all Letters of Credit have expired or been canceled and the Commitments have been canceled.

This opinion letter is delivered to you pursuant to Section 5.1.3 of the Agreement. Capitalized terms used but not otherwise defined herein shall have the meanings given to them in the Agreement. In our capacity as counsel for Borrower, we have examined executed originals or telecopies of executed originals of the Agreement and the initial Notes under the Agreement (the "Loan Documents") and all other certificates, instruments or documents that have been executed and delivered to you by Borrower today in connection with the Agreement. We have also examined and relied upon originals or copies, certified or otherwise authenticated to our 106 Union Bank of Switzerland December 24, 1997 Page 2 satisfaction, of such corporate records of Borrower, certificates of officers of Borrower, certificates and letters of public officials, and other instruments and documents as we have deemed necessary to require as a basis for the opinions hereinafter expressed. In such examination, we have assumed the genuineness and authenticity of all documents submitted to us as originals (other than the Loan Documents), the conformity with genuine and authentic originals of all documents submitted to us as copies, and the genuineness of all signatures (other than the signatures on behalf of Borrower on the Loan Documents). Where facts material to the opinions hereinafter expressed were not independently established by us, we have relied upon the representations and warranties made to you by Borrower in the Loan Documents and upon oral and written statements of and information furnished by officers of Borrower and its Subsidiaries, where we deemed such reliance appropriate under the circumstances. We have necessarily assumed the accuracy and complete-ness of such representations, warranties, statements and other information. Based on the foregoing and on the assumptions hereinafter set forth, and subject to the exceptions, limitations and qualifications hereinafter expressed, it is our opinion that: 1. Borrower is a duly incorporated and validly existing corporation in good standing under the laws of the State of Delaware and has the corporate power and authority to own its property and assets and to transact the business in which it is engaged. Borrower is duly qualified and is authorized to do business and is in good standing as a foreign corporation in the State of Oklahoma. Borrower has the corporate power to execute, deliver and carry out the terms and provisions of each of the Loan Documents to which it is a party and has taken all necessary corporate action to authorize the execution, delivery and performance by it of each of such Loan Documents. 2. The execution, delivery and performance by Borrower of the Agreement and each other Loan Document executed by it are within its corporate powers, have been duly authorized by all necessary corporate action, and do not (i) contravene Borrower's Organic Documents; (ii) to the knowledge of the undersigned, contravene any contractual restriction, law or governmental regulation or court decree or order binding on or affecting Borrower; or (iii) to the knowledge of the undersigned, result in, or require the creation or imposition of, any Lien on any of Borrower's properties. 3. No authorization or approval or other action by, and no notice to or filing with, any governmental authority or regulatory body pursuant to any law or any rule or order of general application is required for the due execution, delivery or performance by Borrower of any Loan Document to which it is a party, except as has been obtained or made. 107 Union Bank of Switzerland December 24, 1997 Page 3 4. Neither Borrower nor any of its Subsidiaries is an "investment company" within the meaning of the Investment Company Act of 1940, as amended, or a "holding company," or a "subsidiary company" of a "holding company," or an "affiliate" of a "holding company" or of a "subsidiary company" of a "holding company," within the meaning of the Public Utility Holding Company Act of 1935, as amended. 5. Each of the Loan Documents to which Borrower is a party has been duly executed and delivered by Borrower. Assuming solely for purposes of this opinion that the internal laws of the State of Texas were to govern the Loan Documents, the Loan Documents constitute the legal, valid and binding obligations of Borrower enforceable in accordance with their respective terms, except as enforcement thereof may be limited by applicable bankruptcy, insolvency, reorganization or other similar laws affecting creditors' rights generally and equitable principles of general applicability. 6. To the knowledge of the undersigned, there is no pending or threatened litigation, action, proceeding, or labor controversy affecting Borrower or any of its Subsidiaries, properties, businesses, assets or revenues, which purports to affect the legality, validity or enforceability of, or the rights and remedies of the Agent and the Lenders under, the Agreement or any other Loan Document. The opinions expressed above are based in part upon the assumptions, and are subject to the exceptions, limitations and qualifications, set forth below: (a) Whenever any opinion expressed herein with respect to any matter is qualified by the phrase "to the knowledge of the undersigned," such phrase (A) indicates that (i) no information has come to the attention of any attorney of this firm who has devoted substantive attention to the transactions contemplated in the Agreement that has given any such person actual knowledge concerning such matter different from that expressed in such opinion; (ii) except as otherwise stated herein, we have not undertaken any independent investigation with respect to such matter but have relied on representations made by Borrower in the Loan Documents and on information otherwise provided to us by it; and (iii) no inference that any such person has actual knowledge concerning such matters should be drawn from the fact of our representation of Borrower and its Subsidiaries or our expression of such opinion; and (B) does not encompass the actual knowledge of any attorney of this firm who obtained such knowledge in his capacity as a director of Borrower. We wish to advise you that Harold F. Kleinman, a shareholder of this firm, is a director of Borrower. 108 Union Bank of Switzerland December 24, 1997 Page 4 (b) Except as expressly set forth herein, we have made no independent investigation as to the accuracy or completeness of any representation, warranty, data or other information, written or oral, made or furnished in or in connection with the Loan Documents, or otherwise. (c) We do not purport to be experts as to the laws of any jurisdiction other than the State of Texas and the United States of America, and we express no opinion herein with respect to the laws of any such other jurisdiction, except insofar as the matters covered by the foregoing opinions may involve or be governed by or construed under the General Corporation Law of the State of Delaware. Our opinion regarding the General Corporation Law of the State of Delaware is confined to our reading thereof without application of judicial or administration interpretations thereof. Insofar as the matters covered by the opinions expressed in paragraph 5 above may involve or be governed by or construed under the laws of any jurisdiction other than the State of Texas, we have necessarily assumed, without knowing, and without making any investigation to determine, that such laws are the same as those of the State of Texas and that the courts of any such other jurisdiction would construe and apply such laws in the same manner as would the courts of the State of Texas. (d) In rendering certain of the opinions expressed above, we have assumed that you (i) are duly authorized to execute and deliver (or accept), and have duly executed and delivered (or accepted), the Loan Documents required to be executed and delivered (or accepted) by you and (ii) will fund the Loans to the extent required to be funded by you under the Agreement. (e) We express no opinion concerning (i) any right of any Agent, Co-Agent or any Lender or any other person to be indemnified against (or released from the consequences of) its own negligence; (ii) the enforceability of any obligations of any party other than Borrower; (iii) the effectiveness or enforceability of provisions regarding exclusive jurisdiction or venue; or (iv) the effectiveness or enforceability of any waiver of the right to trial by jury. This opinion letter is to be limited in its use to reliance by you and your counsel in consummating the Agreement. No other person or entity (other than Assignee Lenders) may rely or claim reliance on any opinion expressed herein except with our express written consent. 109 Union Bank of Switzerland December 24, 1997 Page 5 We assume no obligation to supplement this opinion if, after the date hereof, any applicable law changes or we become aware of any facts that might change the opinions set forth herein.
