On the terms and conditions hereinafter set forth, each Bank agrees severally to make Advances to Borrowers from time to time during the period beginning on the Effective Date and ending on the Maturity Date in such amounts as either Borrower may request up to an amount not to exceed, in the aggregate principal amount outstanding at any time, the Revolving Commitment. Subject to the terms hereof, the Borrowers may borrow, repay and reborrow hereunder. The obligation of Borrowers shall be joint and several hereunder shall be evidenced by this Agreement and the Note or Notes issued in connection herewith, said Note or Notes to be as described in Section 3 hereof. Notwithstanding any other provision of this Agreement, no Advance shall be required to be made hereunder if any Default or Event of Default (as hereinafter defined) has occurred and is continuing. Each Advance under the Revolving Commitment shall be an amount of at least $1,000,000 or a whole number multiple thereof. Irrespective of the face amount of the Note or Notes, the Banks shall never have the obligation to Advance any amount or amounts in excess of the Revolving Commitment or to increase the Revolving Commitment. (b) Procedure for Borrowing. Whenever either Borrower desires an Advance hereunder, it shall give Agent telegraphic, telex, facsimile or telephonic notice ("Notice of Borrowing") of such requested Advance, which in the case of telephonic notice, shall be promptly confirmed in writing. Each Notice of Borrowing shall be in the form of Exhibit "A" attached hereto and shall be received by Agent not later than 11:00 a.m. Chicago, Illinois time, (i) one Business Day prior to the date upon which any such -11- Advance is requested to be funded (the "Borrowing Date") in the case of the Base Rate Loan, or (ii) three (3) Business Days prior to any proposed Borrowing Date in the case of LIBOR Loans. Upon receipt of such Notice, Agent shall immediately advise each Bank thereof; provided, that if the Banks have received at least one (1) Business Day's notice of such Advance prior to funding of a Base Rate Loan, or at least three (3) Business Days' notice of each Advance prior to funding in the case of a LIBOR Loan, each Bank shall provide Agent at its office at 1 Bank One Plaza, 10th Floor, Chicago, Illinois 60670, not later than 1:00 p.m., Chicago, Illinois time, on the Borrowing Date, in immediately available funds, its pro rata share of the requested Advance, but the aggregate of all such fundings by each Bank shall never exceed such Bank's Revolving Commitment. Not later than 2:00 p.m., Chicago, Illinois time, on the Borrowing Date, Agent shall make available to Borrowers at the same office, in like funds, the aggregate amount of such requested Advance. Neither Agent nor any Bank shall incur any liability to Borrowers in acting upon any Notice referred to above which Agent or such Bank believes in good faith to have been given by a duly authorized officer or other person authorized to borrow on behalf of Borrowers or for otherwise acting in good faith under this Section 2(b). Upon funding of Advances by Banks in accordance with this Agreement, pursuant to any such Notice of Borrowing, Borrowers shall have effected Advances hereunder. (c) Letters of Credit. On the terms and conditions hereinafter set forth, the Agent shall from time to time during the period beginning on the Effective Date and ending on the Maturity Date upon request of either Borrower issue standby and/or commercial Letters of Credit for the account of either Borrower (the "Letters of Credit") in such face amounts as either Borrower may request, but not to exceed in the aggregate face amount at any time outstanding the sum of Twenty-Five Million Dollars ($25,000,000). The face amount of all Letters of Credit issued and outstanding hereunder shall be considered as non-interest bearing Advances (but not as Tranches) on the Revolving Commitment and all payments made by the Agent on such Letters of Credit shall be considered as Advances under the Notes. Each letter of Credit issued for the account of either Borrower hereunder shall (i) be in favor of such beneficiaries as specifically requested by either Borrower, (ii) have an expiration date not exceeding the earlier of (A) one year after its date of issuance or (B) five (5) Business Days prior to the Maturity Date, and (iii) contain such other reasonable terms and provisions as may be required by Agent. Any Letter of Credit with a one-year expiry date may provide for automatic renewal thereof for additional one-year periods (but shall in no event extend beyond the fifth (5th) Business Day prior to the Maturity Date) unless the issuer provides prior notice of non-renewal thereof to the beneficiary. Each Bank (other than Agent) agrees that, upon issuance of any Letter of Credit hereunder, it shall automatically acquire a participation in the Agent's liability under such Letter of Credit in an amount equal to such Bank's Revolving Commitment Percentage of such liability, and each Bank (other than Agent) thereby shall absolutely, unconditionally and irrevocably assume, as primary obligor and not as surety, and shall be unconditionally obligated to Agent to pay and discharge when due, its Revolving Commitment Percentage of Agent's liability under such Letter of Credit. Borrowers hereby unconditionally agree to immediately pay and reimburse the Agent for the amount of each demand for payment under any Letter of Credit that is in compliance with the provisions of any such Letter of Credit at or prior to the date on which payment is to be made by the Agent to the beneficiary thereunder, without presentment, demand, protest or other formalities of any kind. Upon receipt from any beneficiary of any Letter of Credit of any demand for payment under such Letter of Credit, the Agent shall promptly notify Borrowers of the demand and the date upon which such payment is to be made by the Agent to such beneficiary in respect of such demand. Forthwith upon receipt of such notice from the Agent, Borrowers shall advise the Agent whether or not they intend to borrow hereunder to finance their obligations to reimburse the Agent, and if so, submit a Notice of Borrowing as provided in Section 2(b) hereof. If Borrowers fail to immediately pay and reimburse Agent as aforesaid, whether by borrowing hereunder or otherwise, Borrowers hereby authorize Agent to make an Advance as a Base Rate Loan in the amount of any payment made by Agent with respect to any Letter of Credit. The failure of the Borrowers to pay such amounts in full to the Agent as required herein by the date specified by the Agent shall result in the Borrowers being liable for interest on such amounts for the number of days that elapse -12- from the day Agent honors such draft to the date on which such amounts are paid to the Agent by the Borrowers at a rate per annum equal to the Base Rate. (d) Procedure for Obtaining Letters of Credit. The amount and date of issuance, renewal, extension or reissuance of a Letter of Credit pursuant to the Banks' commitment above in Section 2(c) shall be designated by Borrowers' written request delivered to Agent at least three (3) Business Days prior to the date of such issuance, renewal, extension or reissuance. Concurrently with or promptly following the delivery of the request for a Letter of Credit, Borrowers shall execute and deliver to the Agent an application and agreement with respect to the Letter of Credit, said application and agreement to be in the form used by the Agent. If there is any conflict between the provisions of any such form and the terms of this Agreement, the terms of this Agreement shall prevail. The Agent shall not be obligated to issue, renew, extend or reissue such Letters of Credit if (A) the amount thereon when added to the amount of the outstanding Letters of Credit exceeds Twenty-Five Million Dollars ($25,000,000) or (B) the amount thereof when added to the Total Outstandings would exceed the Revolving Commitment. Borrowers agree to pay the Agent for the benefit of the Banks commissions for issuing the Letters of Credit (calculated separately for each Letter of Credit) in an amount equal to the LIBOR Margin then in effect times the face amount of the Letter of Credit. Provided, however, that if a Default or Event of Default has occurred and is continuing said fee shall be an amount equal to two percent (2%) per annum on the face amount of the Letter of Credit. Borrowers further agree to pay Agent (i) an additional fee equal to one-eighth of one percent (.125%) per annum (based on the actual days elapsed in a year consisting of 365 or, if appropriate, 366 days) on the maximum face amount of each Letter of Credit, and (ii) an amendment fee for any amendment to letters of credit issued hereunder, said fee to be in the amount of $50.00 per amendment and shall be due upon the issuance of such amendment. Such commissions shall be payable prior to the issuance of each Letter of Credit, based on the term of the particular Letter of Credit, and thereafter on each annual anniversary date of such issuance, or any date of an extension, while such Letter of Credit is outstanding. (e) Voluntary Reduction of Revolving Commitment. Borrowers may at any time, or from time to time, upon not less than three (3) Business Days prior written notice to Agent, reduce or terminate the Revolving Commitment; provided, however, that (i) each reduction in the Revolving Commitment must be in the amount of at least $1,000,000 or in increments of $1,000,000 and (ii) each reduction must be accompanied by a prepayment of the Notes in the amount by which the outstanding principal balance of the Notes exceeds the Revolving Commitment as reduced pursuant to this Section 2(e). (f) Type and Number of Advances. Any Advance under the Revolving Commitment may be a Base Rate Loan or a LIBOR Loan, or any combination thereof, as selected by Borrowers pursuant to Section 4 hereof. The total number of LIBOR Loans that may be outstanding at any time may never exceed six (6). (g) Status of Obligations. The obligations of the Borrowers hereunder are joint and several. The obligations of the Banks under the Revolving Commitment are several and not joint. The failure of any Bank to make an Advance required to be made by it shall not relieve any other Bank of its obligation to make its Advance, and no Bank shall be responsible for the failure of any other Bank to make the Advance to be made by such other Bank. No Bank shall be required to lend hereunder any amount in excess of its legal lending limit; however, each Bank hereunder covenants that the Revolving Commitment does not, as of the date hereof, exceed its legal lending limit. (h) Mandatory Reduction of Revolving Commitment. Notwithstanding anything to the contrary herein, (i) on December 31, 2003, the Revolving Commitment shall be reduced to $64,285,715, and (ii) on December 31, 2004, the Revolving Commitment shall automatically be reduced to $53,571,430. Provided, however, that if on either such date, the then outstanding principal balance of the Notes exceeds -13- the Revolving Commitment, as reduced pursuant to this Section 2(h), then, in such event, the Borrowers shall immediately prepay to the Agent for the pro rata benefit of the Banks, an amount equal to such excess. 3. NOTES EVIDENCING LOANS. The loans described above in Section 2 shall be evidenced by notes of the Borrowers as follows: (a) Form of Notes. The Revolving Loans shall be evidenced by Notes in the aggregate face amount of $75,000,000, and shall be in the form of Exhibit "B" hereto with appropriate insertions. Notwithstanding the face amount of the Notes, the actual principal amount due from Borrowers to Banks on account of the Notes, as of any date of computation, shall be the sum of Advances then and theretofore made on account thereof, plus outstanding Reimbursement Obligations less all principal payments actually received by Banks in collected funds with respect thereto. Although the Notes may be dated as of the Effective Date, interest in respect thereof shall be payable only for the period during which the loans evidenced thereby are outstanding and, although the stated amount of the Notes may be higher, the Notes shall be enforceable, with respect to Borrowers' obligation to pay the principal amount thereof, only to the extent of the unpaid principal amount of the loans. (b) Issuance of Additional Notes. At the Effective Date there shall be outstanding Notes in the aggregate face amount of $75,000,000 payable to the order of the Banks for each such Bank's Pro Rata Part of the Revolving Commitment. From time to time new Notes may be issued to other Banks as such Banks become parties to this Agreement. Upon request from Agent, Borrowers shall execute and deliver to Agent any such new or additional Notes. From time to time as new Notes are issued the Agent shall require that each Bank exchange their Notes for newly issued Notes to reflect the extent of each Bank's Revolving Commitments hereunder. (c) Interest Rates. The unpaid principal balance of all outstanding Advances under the Notes shall bear interest from time to time as set forth in Section 4 hereof. (d) Payment of Interest. Interest on the Notes shall be payable to the Agent for the ratable benefit of the Banks on each Interest Payment Date. (e) Payment of Principal. Principal of the Notes shall be due and payable to the Agent for the ratable benefit of the Banks on the Maturity Date unless earlier due in whole or in part as a result of an acceleration of the amount due or pursuant to the mandatory prepayment provisions of Sections 8(b) hereof. (f) Payment to Banks. Each Bank's Pro Rata Part of payment or prepayment of the Revolving Loans shall be directed by wire transfer to such Bank by the Agent at the address provided to the Agent for such Bank for payments no later than 2:00 p.m., Chicago, Illinois, time on the Business Day such payments or prepayments are deemed hereunder to have been received by Agent; provided, however, in the event that any Bank shall have failed to make an Advance as contemplated under Section 2 hereof (a "Defaulting Bank") and the Agent or another Bank or Banks shall have made such Advance, payment received by Agent for the account of such Defaulting Bank or Banks shall not be distributed to such Defaulting Bank or Banks until such Advance or Advances shall have been repaid in full to the Bank or Banks who funded such Advance or Advances. Any payment or prepayment received by Agent at any time after 12:00 noon, Chicago, Illinois, time on a Business Day shall be deemed to have been received on the next Business Day. Interest shall cease to accrue on any principal as of the end of the day preceding the Business Day on which any such payment or prepayment is deemed hereunder to have been received by Agent. Payment by the Borrowers of any principal, interest or other fees or expenses due hereunder to the Agent shall extinguish the obligations of Borrowers to each Bank for such principal, interest or other fees or expenses actually paid. -14- (g) Sharing of Payments, Etc. If any Bank shall obtain any payment (whether voluntary, involuntary, or otherwise) on account of the Revolving Loans, (including, without limitation, any set-off) which is in excess of its Pro Rata Part of payments on the Revolving Loans such Bank shall purchase from the other Banks such participation as shall be necessary to cause such purchasing Bank to share the excess payment pro rata with each of them; provided that, if all or any portion of such excess payment is thereafter recovered from such purchasing Bank, the purchase shall be rescinded and the purchase price restored to the extent of the recovery. Borrowers agree that any Bank so purchasing a participation from another Bank pursuant to this Section may, to the fullest extent permitted by law, exercise all of its rights of payment (including the right of offset) with respect to such participation as fully as if such Bank were the direct creditor of Borrowers in the amount of such participation. (h) Non-Receipt of Funds by the Agent. Unless the Agent shall have been notified by a Bank or Borrowers (the "Payor") prior to the date on which such Bank is to make payment to the Agent of the proceeds of a Revolving Loans to be made by it hereunder or any Borrower is to make a payment to the Agent for the account of one or more of the Banks, as the case may be (such payment being herein called the "Required Payment"), which notice shall be effective upon receipt, that the Payor does not intend to make the Required Payment to the Agent, the Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available to the intended recipient on such date and, if the Payor has not in fact made the Required Payment to the Agent, the recipient of such payment shall, on demand, pay to the Agent the amount made available to it together with interest thereon in respect of the period commencing on the date such amount was made available by the Agent until the date the Agent recovers such amount at the rate applicable to such portion of the applicable Revolving Loan. 4. INTEREST RATES. (a) Options. (i) Base Rate Loans. On all Base Rate Loans, the Borrowers agree, jointly and severally, to pay interest on the Revolving Loans calculated on the basis of the actual days elapsed in a year consisting of 365 or, if appropriate 366 days, with respect to the unpaid principal amount of each Base Rate Loan from the date the proceeds thereof are made available to Borrowers until maturity (whether by acceleration or otherwise), at a varying rate per annum equal to the lesser of (i) the Maximum Rate (defined herein), or (ii) the Base Rate. Subject to the provisions of this Agreement as to prepayment, the principal of the Notes representing Base Rate Loans shall be payable as specified in Section 3(e) hereof and the interest in respect of each Base Rate Loan shall be payable on each Interest Payment Date. Past due principal and, to the extent permitted by law, past due interest in respect to each Base Rate Loan, shall bear interest, payable on demand, at a rate per annum equal to the Default Rate. (ii) LIBOR Loans. On all LIBOR Loans, the Borrowers agree, jointly and severally, to pay interest calculated on the basis of a year consisting of 360 days with respect to the unpaid principal amount of each LIBOR Loan from the date the proceeds thereof are made available to Borrowers until maturity (whether by acceleration or otherwise), at a varying rate per annum equal to the lesser of (i) the Maximum Rate, or (ii) the LIBOR Rate. Subject to the provisions of this Agreement with respect to prepayment, the principal of the Notes shall be payable as specified in Section 3(e) hereof and the interest with respect to each LIBOR Loan shall be payable on each Interest Payment Date. Past due principal and, to the extent permitted by law, past due interest -15- shall bear interest, payable on demand, at a rate per annum equal to the Default Rate. Upon three (3) Business Days' written notice prior to the making by the Banks of any LIBOR Loan (in the case of the initial Interest Period therefor) or the expiration date of each succeeding Interest Period (in the case of subsequent Interest Periods therefor), Borrowers shall have the option, subject to compliance by Borrowers with all of the provisions of this Agreement, as long as no Event of Default exists, to specify whether the Interest Period commencing on any such date shall be a one (1), two (2), three (3) or six (6) month period. If Agent shall not have received timely notice of a designation of such Interest Period as herein provided, Borrowers shall be deemed to have elected to convert all maturing LIBOR Loans to Base Rate Loans. (b) Interest Rate Determination. The Agent shall determine each interest rate applicable to the Revolving Loans hereunder pursuant to the terms of this Agreement. The Agent shall give prompt notice to Borrowers of each rate of interest so determined and its determination thereof shall be conclusive absent error. (c) Conversion Option. Borrowers may elect from time to time (i) to convert all or any part of its LIBOR Loans to Base Rate Loans by giving Agent irrevocable notice of such election in writing prior to 10:00 a.m. (Chicago, Illinois time) on the conversion date and such conversion shall be made on the requested conversion date, provided that any such conversion of LIBOR Loan shall only be made on the last day of the Interest Period with respect thereof, (ii) to convert all or any part of its Base Rate Loans to LIBOR Loans by giving the Agent irrevocable written notice of such election three (3) Business Days prior to the proposed conversion and such conversion shall be made on the requested conversion date or, if such requested conversion date is not a Business Day, on the next succeeding Business Day. Any such conversion shall not be deemed to be a prepayment of any of the loans for purposes of this Agreement on the Notes. (d) Recoupment. If at any time the applicable rate of interest selected pursuant to Sections 4(a)(i) or 4(a)(ii) above shall exceed the Maximum Rate, thereby causing the interest on the Notes to be limited to the Maximum Rate, then any subsequent reduction in the interest rate so selected or subsequently selected shall not reduce the rate of interest on the Notes below the Maximum Rate until the total amount of interest accrued on the Note equals the amount of interest which would have accrued on the Notes if the rate or rates selected pursuant to Sections 4(a)(i) or (ii), as the case may be, had at all times been in effect. 5. SPECIAL PROVISIONS RELATING TO LOANS. (a) Unavailability of Funds or Inadequacy of Pricing. In the event that, in connection with any proposed LIBOR Loan, the Agent reasonably determines, which determination shall, absent manifest error, be final, conclusive and binding upon all parties, due to changes in circumstances since the date hereof, adequate and fair means do not exist for determining the LIBOR Rate or such rate will not accurately reflect the costs to the Banks of funding LIBOR Loans for such Interest Period, the Agent shall give notice of such determination to the Borrowers and the Banks, whereupon, until the Agent notifies the Borrowers and the Banks that the circumstances giving rise to such suspension no longer exist, the obligations of the Banks to make, continue, or convert Loans into LIBOR Loans shall be suspended, and all loans to Borrowers shall be Base Rate Loans during the period of suspension. (b) Change in Laws. If at any time any new law or any change in existing laws or in the interpretation of any new or existing laws shall make it unlawful for any Bank to make or continue to maintain or fund LIBOR Loans hereunder, then such Bank shall promptly notify Borrowers in writing and such Bank's obligation to make, continue, or convert Loans into, LIBOR Loans under this Agreement shall be suspended until it is no longer unlawful for such Bank to make or maintain LIBOR Loans. Upon receipt -16- of such notice, Borrowers shall either repay the outstanding LIBOR Loans owed to the Banks, without penalty, on the last day of the current Interest Periods (or, if any Bank may not lawfully continue to maintain and fund such LIBOR Loans, immediately), or Borrowers may convert such LIBOR Loans at such appropriate time to Base Rate Loans. (c) Increased Cost or Reduced Return. (i) If, after the date hereof, the adoption of any applicable law, rule, or regulation, or any change in any applicable law, rule, or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank with any request or directive (whether or not having the force of law) of any such governmental authority, central bank, or comparable agency: (A) shall subject such Bank to any tax, duty, or other charge with respect to any LIBOR Loan, its Notes, or its obligation to make LIBOR Loans, or change the basis of taxation of any amounts payable to such Bank under this Agreement or its Notes in respect of any LIBOR Loan (other than franchise taxes and taxes imposed on the overall net income of such Bank); (B) shall impose, modify, or deem applicable any reserve, special deposit, assessment, or similar requirement (other than reserve requirements, if any, taken into account in the determination of the LIBOR Rate) relating to any extensions of credit or other assets of, or any deposits with or other liabilities or commitments of, such Bank, including the Commitment of such Bank hereunder; or (C) shall impose on such Bank or on the London interbank market any other condition affecting this Agreement or its Notes or any of such extensions of credit or liabilities or commitments; and the result of any of the foregoing is to increase the cost to such Bank of making, converting into, continuing, or maintaining any LIBOR Loan or to reduce any sum received or receivable by such Bank under this Agreement or its Notes with respect to any LIBOR Loan, then Borrowers shall pay to such Bank on demand such amount or amounts as will reasonably compensate such Bank for such increased cost or reduction. (ii) If, after the date hereof, any Bank shall have determined that the adoption of any applicable law, rule, or regulation regarding capital adequacy or any change therein or in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such governmental authority, central bank, or comparable agency, has or would have the effect of reducing the rate of return on the capital of such Bank or any corporation controlling such Bank as a consequence of such Bank's obligations hereunder to a level below that which such Bank or such corporation could have achieved but for such adoption, change, request, or directive (taking into consideration its policies with respect to capital adequacy), then from time to time upon demand Borrowers shall pay to such Bank such additional amount or amounts as will reasonably compensate such Bank for such reduction. -17- (iii) Each Bank shall promptly notify Borrowers and Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Bank to compensation pursuant to this Section 5(c) and will designate a separate lending office, if applicable, if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Bank, be otherwise disadvantageous to it. Any Bank claiming compensation under this Section 5(c) shall furnish to Borrowers and Agent a statement setting forth the additional amount or amounts to be paid to it hereunder which shall be conclusive in the absence of manifest error. In determining such amount, such Bank may use any reasonable averaging and attribution methods. (iv) Any Bank giving notice to the Borrowers through the Agent, pursuant to Section 5(c) shall give to the Borrowers a statement signed by an officer of such Bank setting forth in reasonable detail the basis for, and the calculation of such additional cost, reduced payments or capital requirements, as the case may be, and the additional amounts required to compensate such Bank therefor. (v) Within five (5) Business Days after receipt by the Borrowers of any notice referred to in Section 5(c), the Borrowers shall pay to the Agent for the account of the Bank issuing such notice such additional amounts as are required to compensate such Bank for the increased cost, reduce payments or increase capital requirements identified therein, as the case may be. If any Bank requests compensation by Borrowers under this Section 5(c), Borrowers may, by notice to such Bank (with a copy to Agent), suspend the obligation of such Bank to make or continue LIBOR Loans or to convert all or part of the Base Rate Loans owing to such Bank to LIBOR Loans, until the event or condition giving rise to such request ceases to be in effect (in which case the provisions of Section 5(c) shall be applicable); provided that such suspension shall not affect the right of such Bank to receive the compensation so requested. (d) Discretion of Bank as to Manner of Funding. Notwithstanding any provisions of this Agreement to the contrary, each Bank shall be entitled to fund and maintain its funding of all or any part of its Loan in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if each Bank had actually funded and maintained each LIBOR Loan through the purchase of deposits having a maturity corresponding to the last day of the Interest Period applicable to such LIBOR Loan and bearing an interest rate to the applicable interest rate for such LIBOR Period. (e) Breakage Fees. Without duplication under any other provision hereof, if any Bank incurs any loss, cost or expense including, without limitation, any loss of profit and loss, cost, expense or premium reasonably incurred by reason of the liquidation or re-employment of deposits or other funds acquired by such Bank to fund or maintain any LIBOR Loan or the relending or reinvesting of such deposits or amounts paid or prepaid to the Banks as a result of any of the following events other than any such occurrence as a result in the change of circumstances described in Sections 5(a) and (b): (i) any payment, prepayment or conversion of a LIBOR Loan on a date other than the last day of its Interest Period (whether by acceleration, prepayment or otherwise); (ii) any failure to make a principal payment of a LIBOR Loan on the due date thereof; or -18- (iii) any failure by the Borrowers to borrow, continue, prepay or convert to a LIBOR Loan on the dates specified in a notice given pursuant to Section 2(b) or 4(c) hereof; then the Borrowers shall pay to such Bank such amount as will reimburse such Bank for such loss, cost or expense. If any Bank makes such a claim for compensation, it shall furnish to Borrowers and Agent a statement setting forth the amount of such loss, cost or expense in reasonable detail (including an explanation of the basis for and the computation of such loss, cost or expense) and the amounts shown on such statement shall be conclusive and binding absent manifest error. 6.

EVENTS OF DEFAULT. Any one or more of the following events shall be considered an "Event of Default" as that term is used herein: (a) Borrowers shall fail to pay when due or declared due the principal of, and the interest on, the Notes, or any fee or any other indebtedness of Borrowers incurred pursuant to this Agreement or any other Loan Document; or (b) Any representation or warranty made under this Agreement, or in any certificate or statement furnished or made to the Banks pursuant hereto, or in connection herewith, or in connection with any document furnished hereunder, shall prove to be untrue in any material respect as of the date on which such representation or warranty is made (or deemed made), or any representation, statement (including financial statements), certificate, report or other data furnished or to be furnished or made under any Loan Document, including this Agreement, proves to have been untrue in any material respect, as of the date as of which the facts therein set forth were stated or certified; or (c) Default shall be made in the due observance or performance of any of the covenants or agreements contained in the Loan Documents, including this Agreement (excluding covenants contained in Section 12 of the Agreement for which there is no cure period), and such default shall continue for more than thirty (30) days after the giving of written notice thereof by the Agent to the Borrowers; or (d) Default shall be made in the due observance or performance of the covenants contained in Section 12 of this Agreement; or (e) Default shall be made in respect of any obligation for borrowed money, other than the Notes, for which either Borrower or any Subsidiary is liable (directly, by assumption, as guarantor or otherwise), or any obligations secured by any mortgage, pledge or other security interest, lien, charge or encumbrance with respect thereto, on any asset or property of either Borrower or any Subsidiary or in respect of any agreement relating to any such obligations unless neither Borrower nor any Subsidiary is liable for same (i.e., unless remedies or recourse for failure to pay such obligations is limited to foreclosure of the collateral security therefor), and if such default shall continue beyond the applicable grace period, if any; or (f) Either Borrower or any Subsidiary shall commence a voluntary case or other proceedings seeking liquidation, reorganization or other relief with respect to itself or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking an appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due, or shall take any corporate action authorizing the foregoing; or -34- (g) An involuntary case or other proceeding, shall be commenced against either Borrower or any Subsidiary seeking liquidation, reorganization or other relief with respect to it or its debts under any bankruptcy, insolvency or similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of thirty (30) days; or an order for relief shall be entered against either Borrower or any Subsidiary under the federal bankruptcy laws as now or hereinafter in effect; or (h) A final judgment or order for the payment of money in excess of $1,000,000 (or judgments or orders aggregating in excess of $1,000,000) shall be rendered against either Borrower or any Subsidiary and such judgments or orders shall continue unsatisfied and unstayed for a period of thirty (30) days unless such judgment or orders are fully covered by insurance or supersedeas bond; or (i) In the event the aggregate principal amount outstanding under the Notes shall at any time exceed the Revolving Commitment established for the Notes, and Borrowers shall fail to comply with the provisions of Section 8(b) hereof; or (j) A Change of Control shall occur; or (k) A Change of Management shall occur; or (l) Default shall occur under the Pacific Credit Agreement; or (m) Default shall occur on a Rate Management Transaction. Upon occurrence of any Event of Default specified in Subsections 13(f) and (g) hereof, the entire principal amount due under the Notes and all interest then accrued thereon, and any other liabilities of Borrowers hereunder, shall become immediately due and payable all without notice and without presentment, demand, protest, notice of protest or dishonor or any other notice of default of any kind, all of which are hereby expressly waived by Borrowers. In any other Event of Default, the Agent, upon request of Majority Banks, shall by notice in writing to Borrowers declare the principal of, and all interest then accrued on, the Notes and any other liabilities hereunder to be forthwith due and payable, whereupon the same shall forthwith become due and payable without presentment, demand, protest, notice of intent to accelerate, notice of acceleration or other notice of any kind, all of which Borrowers hereby expressly waive, anything contained herein or in the Notes to the contrary notwithstanding. Nothing contained in this Section 13 shall be construed to limit or amend in any way the Events of Default enumerated in the Notes, or any other document executed in connection with the transaction contemplated herein. Upon the occurrence and during the continuance of any Event of Default, the Banks are hereby authorized at any time and from time to time and to the extent permitted by applicable law, without notice to Borrowers (any such notice being expressly waived by Borrowers), to set-off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by any of the Banks to or for the credit or the account of Borrowers against any and all of the indebtedness of Borrowers under the Notes and the Loan Documents, including this Agreement, irrespective of whether or not the Banks shall have made any demand under the Loan Documents, including this Agreement or the Notes and although such indebtedness may be unmatured. Any amount set-off by any of the Banks shall be applied against the indebtedness owed the Banks by Borrowers pursuant to this Agreement and the Notes. The Banks agree promptly to notify Borrowers after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Bank under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the Banks may have. -35- 14. THE AGENT AND THE BANKS. (a) Appointment and Authorization. Each Bank hereby appoints Agent as its nominee and agent, in its name and on its behalf: (i) to act as nominee for and on behalf of such Bank in and under all Loan Documents; (ii) to arrange the means whereby the funds of Banks are to be made available to Borrowers under the Loan Documents; (iii) to take such action as may be requested by any Bank under the Loan Documents (when such Bank is entitled to make such request under the Loan Documents); (iv) to receive all documents and items to be furnished to Banks under the Loan Documents; (v) to be the secured party, mortgagee, beneficiary, and similar party in respect of, and to receive, as the case may be, any collateral for the benefit of Banks; (vi) to promptly distribute to each Bank all material information, requests, documents and items received from Borrowers under the Loan Documents; (vii) to promptly distribute to each Bank such Bank's Pro Rata Part of each payment or prepayment (whether voluntary, as proceeds of insurance thereon, or otherwise) in accordance with the terms of the Loan Documents and (viii) to deliver to the appropriate Persons requests, demands, approvals and consents received from Banks. Each Bank hereby authorizes Agent to take all actions and to exercise such powers under the Loan Documents as are specifically delegated to such Agent by the terms hereof or thereof, together with all other powers reasonably incidental thereto. With respect to its commitments hereunder and the Notes issued to it, Agent and any successor Agent shall have the same rights under the Loan Documents as any other Bank and may exercise the same as though it were not the Agent; and the term "Bank" or "Banks" shall, unless otherwise expressly indicated, include Agent and any successor Agent in its capacity as a Bank. Agent and any successor Agent and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of and generally engage in any kind of business with Borrowers, and any person which may do business with Borrowers, all as if Agent and any successor Agent were not Agent hereunder and without any duty to account therefor to the Banks; provided that, if any payments in respect of any property (or the proceeds thereof) now or hereafter in the possession or control of Agent which may be or become security for the obligations of Borrowers arising under the Loan Documents by reason of the general description of indebtedness secured or of property contained in any other agreements, documents or instruments related to any such other business shall be applied to reduction of the obligations of Borrowers arising under the Loan Documents, then each Bank shall be entitled to share in such application according to its pro rata part thereof. Each Bank, upon request of any other Bank, shall disclose to all other Banks all indebtedness and liabilities, direct and contingent, of Borrowers to such Bank as of the time of such request. (b) Note Holders. From time to time as other Banks become a party to this Agreement, Agent shall obtain execution by Borrowers of additional Notes, in the form of Exhibit B hereto, in amounts representing the Revolving Commitment of each such new Bank, up to an aggregate face amount of all Notes not exceeding $75,000,000. The obligation of such Bank shall be governed by the provisions of this Agreement, including but not limited to, the obligations specified in Section 2 hereof. From time to time, Agent may require that the Banks exchange their Notes for newly issued Notes to better reflect the Revolving Commitments of the Banks. Agent may treat the payee of any Note as the holder thereof until written notice of transfer has been filed with it, signed by such payee and in form satisfactory to Agent. (c) Consultation with Counsel. Banks agree that Agent may consult with legal counsel selected by Agent and shall not be liable for any action taken or suffered in good faith by it in accordance with the advice of such counsel. BANKS ACKNOWLEDGE THAT GARDERE WYNNE SEWELL LLP IS COUNSEL FOR BANK ONE, BOTH AS AGENT AND AS A BANK, AND THAT SUCH FIRM DOES NOT REPRESENT ANY OF THE OTHER BANKS IN CONNECTION WITH THIS TRANSACTION. (d) Documents. Agent shall not be under a duty to examine or pass upon the validity, effectiveness, enforceability, genuineness or value of any of the Loan Documents or any other instrument or document furnished pursuant thereto or in connection therewith, and Agent shall be entitled to assume that the same are valid, effective, enforceable and genuine and what they purport to be. -36- (e) Resignation or Removal of Agent. Subject to the appointment and acceptance of a successor Agent as provided below, Agent may resign at any time by giving written notice thereof to Banks and Borrowers, and Agent may be removed at any time with or without cause by Majority Banks. If no successor Agent has been so appointed by Majority Banks (and approved by Borrowers) and has accepted such appointment within 30 days after the retiring Agent's giving of notice of resignation or removal of the retiring Agent, then the retiring Agent may, on behalf of Banks, appoint a successor Agent. Any successor Agent must be approved by Borrowers, which approval will not be unreasonably withheld. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. After any retiring Agent's resignation or removal hereunder as Agent, the provisions of this Section 14 shall continue in effect for its benefit in respect to any actions taken or omitted to be taken by it while it was acting as Agent. (f) Responsibility of Agent. It is expressly understood and agreed that the obligations of Agent under the Loan Documents are only those expressly set forth in the Loan Documents and that Agent, as the case may be, shall be entitled to assume that no Default or Event of Default has occurred and is continuing, unless Agent, as the case may be, has actual knowledge of such fact or has received notice from a Bank or Borrowers that such Bank or Borrowers consider that a Default or an Event of Default has occurred and is continuing and specifying the nature thereof. Neither Agent nor any of their directors, officers, attorneys or employees shall be liable for any action taken or omitted to be taken by them under or in connection with the Loan Documents, except for its or their own gross negligence or willful misconduct. Agent shall incur no liability under or in respect of any of the Loan Documents by acting upon any notice, consent, certificate, warranty or other paper or instrument believed by it to be genuine or authentic or to be signed by the proper party or parties, or with respect to anything which it may do or refrain from doing in the reasonable exercise of its judgment, or which may seem to it to be necessary or desirable. Agent shall not be responsible to Banks for any of Borrowers' recitals, statements, representations or warranties contained in any of the Loan Documents, or in any certificate or other document referred to or provided for in, or received by any Bank under, the Loan Documents, or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of or any of the Loan Documents or for any failure by Borrowers to perform any of their obligations hereunder or thereunder. Agent may employ agents and attorneys-in-fact and shall not be answerable, except as to money or securities received by it or its authorized agents, for the negligence or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. The relationship between Agent and each Bank is only that of agent and principal and has no fiduciary aspects. Nothing in the Loan Documents or elsewhere shall be construed to impose on Agent any duties or responsibilities other than those for which express provision is therein made. In performing its duties and functions hereunder, Agent does not assume and shall not be deemed to have assumed, and hereby expressly disclaims, any obligation or responsibility toward or any relationship of agency or trust with or for Borrowers or any of its beneficiaries or other creditors. As to any matters not expressly provided for by the Loan Documents, Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of all Banks and such instructions shall be binding upon all Banks and all holders of the Notes; provided, however, that Agent shall not be required to take any action which is contrary to the Loan Documents or applicable law. Subject to Section 22 hereof, Agent shall have the right to exercise or refrain from exercising, without notice or liability to the Banks, any and all rights afforded to Agent by the Loan Documents or which Agent may have as a matter of law. Agent shall not have liability to Banks for failure or delay in -37- exercising any right or power possessed by Agent pursuant to the Loan Documents or otherwise unless such failure or delay is caused by the gross negligence of the Agent, in which case only the Agent responsible for such gross negligence shall have liability therefor to the Banks. (g) Independent Investigation. Each Bank severally represents and warrants to Agent that it has made its own independent investigation and assessment of the financial condition and affairs of Borrowers in connection with the making and continuation of its participation hereunder and has not relied exclusively on any information provided to such Bank by Agent in connection herewith, and each Bank represents, warrants and undertakes to Agent that it shall continue to make its own independent appraisal of the credit worthiness of Borrowers while the Notes are outstanding or its commitments hereunder are in force. Agent shall not be required to keep itself informed as to the performance or observance by Borrowers of this Agreement or any other document referred to or provided for herein or to inspect the properties or books of Borrowers. Other than as provided in this Agreement, Agent shall not have any duty, responsibility or liability to provide any Bank with any credit or other information concerning the affairs, financial condition or business of Borrowers which may come into the possession of Agent. (h) Indemnification. Banks agree to indemnify Agent, ratably according to their respective Revolving Commitments on a Pro Rata basis, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any proper and reasonable kind or nature whatsoever which may be imposed on, incurred by or asserted against Agent in any way relating to or arising out of the Loan Documents or any action taken or omitted by Agent under the Loan Documents, provided that no Bank shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from Agent's gross negligence or willful misconduct. Each Bank shall be entitled to be reimbursed by the Agent for any amount such Bank paid to Agent under this Section 14(h) to the extent the Agent has been reimbursed for such payments by Borrowers or any other Person. THE PARTIES INTEND FOR THE PROVISIONS OF THIS SECTION TO APPLY TO AND PROTECT THE AGENT FROM THE CONSEQUENCES OF ANY LIABILITY INCLUDING STRICT LIABILITY IMPOSED OR THREATENED TO BE IMPOSED ON AGENT AS WELL AS FROM THE CONSEQUENCES OF ITS OWN NEGLIGENCE, WHETHER OR NOT THAT NEGLIGENCE IS THE SOLE, CONTRIBUTING OR CONCURRING CAUSE OF ANY SUCH LIABILITY. (i) Benefit of Section 14. The agreements contained in this Section 14 are solely for the benefit of Agent and the Banks and are not for the benefit of, or to be relied upon by, Borrowers, any affiliate of Borrowers or any other person. (j) Pro Rata Treatment. Subject to the provisions of this Agreement, each payment (including each prepayment) by Borrowers and collection by Banks (including offsets) on account of the principal of and interest on the Notes and fees provided for in this Agreement, shall be made Pro Rata; provided, however, in the event that any Defaulting Bank shall have failed to make an Advance as contemplated under Section 3 hereof and Agent or another Bank or Banks shall have made such Advance, payment received by Agent for the account of such Defaulting Bank or Banks shall not be distributed to such Defaulting Bank or Banks until such Advance or Advances shall have been repaid in full to the Bank or Banks who funded such Advance or Advances. (k) Assumption as to Payments. Except as specifically provided herein, unless Agent shall have received notice from Borrowers prior to the date on which any payment is due to Banks hereunder that Borrowers will not make such payment in full, Agent may, but shall not be required to, assume that Borrowers have made such payment in full to Agent on such date and Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent Borrowers shall not have so made such payment in full to Agent, each Bank shall repay to Agent forthwith on demand such amount distributed to such Bank together with interest -38- thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to Agent, at the interest rate applicable to such portion of the Revolving Loans. (l) Other Financings. Without limiting the rights to which any Bank otherwise is or may become entitled, such Bank shall have no interest, by virtue of this Agreement or the Loan Documents, in (a) any present or future loans from, letters of credit issued by, or leasing or other financial transactions by, any other Bank to, on behalf of, or with Borrowers (collectively referred to herein as "Other Financings") other than the obligations hereunder; (b) any present or future guarantees by or for the account of Borrowers which are not contemplated by the Loan Documents; (c) any present or future property taken as security for any such Other Financings; or (d) any property now or hereafter in the possession or control of any other Bank which may be or become security for the obligations of Borrowers arising under any loan document by reason of the general description of indebtedness secured or property contained in any other agreements, documents or instruments relating to any such Other Financings. (m) Interests of Banks. Nothing in this Agreement shall be construed to create a partnership or joint venture between Banks for any purpose. Agent, Banks and Borrowers recognize that the respective obligations of Banks under the Revolving Commitments shall be several and not joint and that neither Agent, nor any of Banks shall be responsible or liable to perform any of the obligations of the other under this Agreement. Each Bank is deemed to be the owner of an undivided interest in and to all rights, titles, benefits and interests belonging and accruing to Agent under the Security Instruments, including, without limitation, liens and security interests in any collateral, fees and payments of principal and interest by Borrowers under the Revolving Commitments on a Pro Rata basis. Each Bank shall perform all duties and obligations of Banks under this Agreement in the same proportion as its ownership interest in the Loans outstanding at the date of determination thereof. (n) Investments. Whenever Agent in good faith determines that it is uncertain about how to distribute to Banks any funds which it has received, or whenever Agent in good faith determines that there is any dispute among the Banks about how such funds should be distributed, Agent may choose to defer distribution of the funds which are the subject of such uncertainty or dispute. If Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if Agent is otherwise required to invest funds pending distribution to the Banks, Agent may invest such funds pending distribution (at the risk of Borrowers). All interest on any such investment shall be distributed upon the distribution of such investment and in the same proportions and to the same Persons as such investment. All monies received by Agent for distribution to the Banks (other than to the Person who is Agent in its separate capacity as a Bank) shall be held by the Agent pending such distribution solely as Agent for such Banks, and Agent shall have no equitable title to any portion thereof. (o) Withholding Tax. Each Bank agrees to furnish (if it is organized under the laws of any jurisdiction other than the United States or any State thereof) to the Agent and the Borrowers prior to the time that the Borrowers are required to make any payment of principal, interest or fees hereunder, to such Bank, duplicate executed originals of either U.S. Internal Revenue Service Form 4224 or U.S. Internal Revenue Service Form 1001 (wherein such Bank claims entitlement to the benefits of a tax treaty that provides for a complete exemption from U.S. federal income withholding tax on all payments hereunder) and a Form W-8 and agrees to provide new Forms 4224 or 1001 and Form W-8, upon the expiration of any previously delivered from or comparable statements in accordance with applicable U.S. law and regulations and amendments thereto, and agrees to comply with all applicable U.S. laws and regulations with regard to such withholding tax exemption. 15. EXERCISE OF RIGHTS. No failure to exercise, and no delay in exercising, on the part of the Agent or the Banks, any right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right. The rights of the Agent and the -39- Banks hereunder shall be in addition to all other rights provided by law. No modification or waiver of any provision of the Loan Documents, including this Agreement, or the Note nor consent to departure therefrom, shall be effective unless in writing, and no such consent or waiver shall extend beyond the particular case and purpose involved. No notice or demand given in any case shall constitute a waiver of the right to take other action in the same, similar or other circumstances without such notice or demand. 16. NOTICES. Any notices or other communications required or permitted to be given by this Agreement or any other documents and instruments referred to herein must be given in writing either by facsimile transmission or personally delivered or couriered or mailed by prepaid certified or registered mail to the party to whom such notice or communication is directed at the address of such party as follows: (a) BORROWERS: c/o ATWOOD OCEANICS, INC. and ATWOOD DEEP SEAS, LTD., 15835 Park Ten Place Drive, Houston, Texas 77084, Facsimile No. (281) 492-0345; Attention: James M. Holland, Senior Vice President and Secretary; (b) AGENT: c/o AGENT, BANK ONE, NA, 1 Bank One Plaza, 10th Floor, IL1-0362, Chicago, Illinois 60670, Facsimile No. (312) 732-3055, Attention: Kenneth J. Fatur, Director, Capital Markets and (c) any Bank at its address shown on any addendum hereto. Any such notice or other communication shall be deemed to have been given (whether actually received or not) on the day it is personally delivered or delivered by facsimile as aforesaid or, if mailed, on the third day after it is mailed as aforesaid. Any party may change its address for purposes of this Agreement by giving notice of such change to the other party pursuant to this Section 16. 17. EXPENSES. Borrowers shall pay (i) all reasonable and necessary out-of-pocket expenses of the Agent, including reasonable fees and disbursements of special counsel for the Agent, in connection with the preparation of this Agreement, the other Loan Documents, title and other due diligence and closing of the transaction described in this Agreement, any waiver or consent hereunder or any amendment hereof or any default or Event of Default or alleged default or Event of Default hereunder, (ii) all reasonable and necessary out-of-pocket expenses of the Agent, including reasonable fees and disbursements of special counsel for the Agent in connection with the preparation of any participation agreement for a participant or participants requested by Borrowers or any amendment thereof and (iii) if a default or an Event of Default occurs, all reasonable and necessary out-of-pocket expenses incurred by the Banks, including fees and disbursements of counsel, in connection with such default and Event of Default and collection and other enforcement proceedings resulting therefrom. THE BORROWERS HEREBY ACKNOWLEDGE THAT GARDERE WYNNE SEWELL LLP IS SPECIAL COUNSEL TO BANK ONE, AS AGENT AND AS A BANK, UNDER THIS AGREEMENT AND THAT IT IS NOT COUNSEL TO, NOR DOES IT REPRESENT THE BORROWERS IN CONNECTION WITH THE TRANSACTIONS DESCRIBED IN THIS AGREEMENT. The Borrowers are relying on separate counsel in the transaction described herein. The Borrowers shall indemnify the Banks against any transfer taxes, document taxes, assessments or charges made by any governmental authority by reason of the execution, delivery and filing of the Loan Documents. The obligations of this Section 17 shall survive any termination of this Agreement, the expiration of the Loans and the payment of the indebtedness of the Borrowers to the Banks hereunder and under the Notes. 18. INDEMNITY. Borrowers agree to indemnify and hold harmless the Banks and their respective officers, employees, agents, attorneys and representatives (singularly, an "Indemnified Party", and collectively, the "Indemnified Parties") from and against any loss, cost, liability, damage or expense (including the reasonable fees and out-of-pocket expenses of counsel to the Banks, including all local counsel hired by such counsel) ("Claim") incurred by the Banks in investigating or preparing for, defending against, or providing evidence, producing documents or taking any other action in respect of any commenced or threatened litigation, administrative proceeding or investigation under any federal securities law, federal or state environmental law, or any other statute of any jurisdiction, or any regulation, or at common law or otherwise, which is alleged to arise out of or is based upon any acts, practices or omissions or alleged acts, practices or omissions of Borrowers or their agents or arises in connection with the duties, obligations or performance of the Indemnified Parties in negotiating, preparing, executing, accepting, keeping, completing, countersigning, issuing, selling, delivering, releasing, assigning, handling, certifying, processing or receiving or taking any other action with respect to the Loan Documents and all documents, items and materials contemplated thereby even if any of the foregoing arises out of an Indemnified Party's ordinary negligence. The indemnity set forth herein shall be in addition to any other obligations or liabilities -40- of Borrowers to the Banks hereunder or at common law or otherwise, and shall survive any termination of this Agreement, the expiration of the Revolving Loans and the payment of all indebtedness of Borrowers to the Banks hereunder and under the Notes, provided that Borrowers shall have no obligation under this Section to the Bank with respect to any of the foregoing arising out of the gross negligence or willful misconduct of any Indemnified Party. If any Claim is asserted against any Indemnified Party, the Indemnified Party shall endeavor to notify Borrowers of such Claim (but failure to do so shall not affect the indemnification herein made except to the extent of the actual harm caused by such failure). The Indemnified Party shall have the right to employ, at Borrowers' expense, counsel of the Indemnified Parties' choosing and to control the defense of the Claim. Borrowers may at its own expense also participate in the defense of any Claim. Each Indemnified Party may employ separate counsel in connection with any Claim to the extent such Indemnified Party believes it reasonably prudent to protect such Indemnified Party. THE PARTIES INTEND FOR THE PROVISIONS OF THIS SECTION TO APPLY TO AND PROTECT EACH INDEMNIFIED PARTY FROM THE CONSEQUENCES OF ANY LIABILITY INCLUDING STRICT LIABILITY IMPOSED OR THREATENED TO BE IMPOSED ON AGENT AS WELL AS FROM THE CONSEQUENCES OF ITS OWN ORDINARY NEGLIGENCE, WHETHER OR NOT THAT NEGLIGENCE IS THE SOLE, CONTRIBUTING, OR CONCURRING CAUSE OF ANY CLAIM. 19. GOVERNING LAW. THIS AGREEMENT IS BEING EXECUTED AND DELIVERED, AND IS INTENDED TO BE PERFORMED, IN HOUSTON, HARRIS, COUNTY, TEXAS, AND THE SUBSTANTIVE LAWS OF TEXAS SHALL GOVERN THE VALIDITY, CONSTRUCTION, ENFORCEMENT AND INTERPRETATION OF THIS AGREEMENT AND ALL OTHER DOCUMENTS AND INSTRUMENTS REFERRED TO HEREIN, UNLESS OTHERWISE SPECIFIED THEREIN. 20. INVALID PROVISIONS. If any provision of this Agreement is held to be illegal, invalid, or unenforceable under present or future laws effective during the term of this Agreement, such provisions shall be fully severable and this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part of this Agreement, and the remaining provisions of the Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance from this Agreement. 21. MAXIMUM INTEREST RATE. Regardless of any provisions contained in this Agreement or in any other documents and instruments referred to herein, the Banks shall never be deemed to have contracted for or be entitled to receive, collect or apply as interest on the Notes any amount in excess of the Maximum Rate, and in the event any Bank ever receives, collects or applies as interest any such excess, or if an acceleration of the maturities of any Notes or if any prepayment by Borrowers result in Borrowers having paid any interest in excess of the Maximum Rate, such amount which would be excessive interest shall be applied to the reduction of the unpaid principal balance of the Notes for which such excess was received, collected or applied, and, if the principal balance of such Note is paid in full, any remaining excess shall forthwith be paid to Borrowers. All sums paid or agreed to be paid to the Banks for the use, forbearance or detention of the indebtedness evidenced by the Notes and/or this Agreement 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 so that the rate or amount of interest on account of such indebtedness does not exceed the Maximum Rate. In determining whether or not the interest paid or payable under any specific contingency exceeds the Maximum Rate of interest permitted by law, Borrowers and the Banks shall, to the maximum extent permitted under applicable law, (i) characterize any non-principal payment as an expense, fee or premium, rather than as interest; and (ii) exclude voluntary prepayments and the effect thereof; and (iii) compare the total amount of interest contracted for, charged or received with the total amount of interest which could be contracted for, charged or received throughout the entire contemplated term of the Notes at the Maximum Rate. For purposes of Section 303 of the Texas Finance Code, to the extent applicable to any Lender or Agent, Borrowers agree that the Maximum Rate shall be the "weekly ceiling" as defined in said Chapter, provided that such Lender or Agent, as applicable, may also rely, to the extent permitted by applicable laws of the State of Texas and the United States of America, on alternative maximum rates of interest under the Texas Finance Code or other laws applicable to such Lender or Agent from time to time if greater. -41- 22. AMENDMENTS OR WAIVERS. Neither this Agreement nor any other Loan Document nor any terms hereof or thereof may be changed, waived or discharged or terminated unless such change, waiver, discharge or termination is in writing signed by the Borrowers and the Majority Banks, provided that no such change, waiver, discharge or termination shall, without the consent of each Bank (other than a Defaulting Bank) affected thereby, (i) extend the Maturity Date (it being understood that any waiver of the application of any prepayment of the Revolving Loans or the method of application of any prepayment shall not constitute any such extension), to reduce the rate or extend the time of payment of interest (other than as a result of waiving the applicability of any post-default increase in interest rates) or fees thereon, or reduce the principal amount thereof, (ii) increase the Revolving Commitment of any Bank over the amount thereof then in effect (it being understood that a waiver of any condition, covenant, Default or Event of Default shall not constitute a change in the terms of any Revolving Commitment of any Bank), (iii) release or permit the release of any Collateral from the Lien of the respective Security Instruments, except as permitted by Sections 12(s) and (12(a)(ii), (iv) amend, modify or waive any provision of this Section 22, (v) reduce the percentage specified in the definition of Majority Banks (it being understood and agreed that, with the consent of the Majority Banks, additional extensions of credit pursuant to this Agreement may be included in the determination of Majority Banks on substantially the same basis as the Revolving Commitments (and related extensions of credit) are included on the Effective Date), (vi) consent to the assignment or transfer by the Borrowers of any of their rights and obligations under this Agreement, (vii) waive, change the timing or amount of, or extend any mandatory reduction in the Revolving Commitment, (viii) waive any of the conditions precedent to the Effective Date or making of any Loan or Advance or issuance of any Letter of Credit, or (ix) amend this sentence. No provision of Section 2, or any other provisions relating to and the issuance of Letters of Credit or the Administrative Agent may be modified without the consent of the Administrative Agent. 23. MULTIPLE COUNTERPARTS. This Agreement may be executed in a number of identical separate counterparts, each of which for all purposes is to be deemed an original, but all of which shall constitute, collectively, one agreement. No party to this Agreement shall be bound hereby until a counterpart of this Agreement has been executed by all parties hereto. 24. CONFLICT. In the event any term or provision hereof is inconsistent with or conflicts with any provision of the Loan Documents, the terms or provisions contained in this Agreement shall be controlling. 25. SURVIVAL. All covenants, agreements, undertakings, representations and warranties made in the Loan Documents, including this Agreement, the Notes or other documents and instruments referred to herein shall survive all closings hereunder and shall not be affected by any investigation made by any party. 26. PARTIES BOUND. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors, assigns, heirs, legal representatives and estates, provided, however, that Borrowers may not, without the prior written consent of the Banks, assign any rights, powers, duties or obligations hereunder. -42- 27. ASSIGNMENTS AND PARTICIPATIONS. (a) Each Bank shall have the right to sell, assign or transfer all or any part of its Note or Notes, its Revolving Commitments and its rights and obligations hereunder to an Eligible Assignee; provided, that with each sale, assignment or transfer (other than to an Affiliate, a Bank or a Federal Reserve Bank), shall require the consent of Borrowers and Agent, which consents will not be unreasonably withheld; provided, however, that no consent of Borrower shall be required if an Event of Default has occurred and is continuing. Any such assignee, transferee or recipient shall have, to the extent of such sale, assignment, or transfer, the same rights, benefits and obligations as it would if it were such Bank and a holder of such Note, Revolving Commitment and rights and obligations, including, without limitation, the right to vote on decisions requiring consent or approval of all Banks or Majority Banks and the obligation to fund its Revolving Commitment; provided, further, that (1) each such sale, assignment, or transfer (other than to an Affiliate, a Bank or a Federal Reserve Bank) shall be in an aggregate principal amount not less than $5,000,000, (2) each remaining Bank shall at all times maintain Revolving Commitments then outstanding in an aggregate principal amount at least equal to $1,000,000; (3) no Bank may offer to sell its Note or Notes, Revolving Commitment, rights and obligations or interests therein in violation of any securities laws; and (4) no such assignments (other than to a Federal Reserve Bank) shall become effective until the assigning Bank and its assignees delivers to Agent and Borrowers an Assignment and Acceptance and the Note or Notes subject to such assignment and other documents evidencing any such assignment. An assignment fee in the amount of $3,000 for each such assignment (other than to an Affiliate, a Bank or the Federal Reserve Bank) will be payable to Agent by assignor or assignee. Within five (5) Business Days after its receipt of copies of the Assignment and Acceptance and the other documents relating thereto and the Note or Notes, Borrowers shall execute and deliver to Agent (for delivery to the relevant assignee) a new Note or Notes evidencing such assignee's assigned Revolving Commitment, and within a reasonable time after delivery of such new Note or Notes to Agent, Agent shall return the old or replaced Note or Notes to Borrower, and if the assignor Bank has retained a portion of its Revolving Commitment, a replacement Note in the principal amount of the Revolving Commitment retained by the assignor (except as provided in the last sentence of this paragraph (a) such Note or Notes, to be in exchange for, but not in payment of, the Note or Notes held by such Bank). On and after the effective date of an assignment hereunder, the assignee shall for all purposes be a Bank, party to this Agreement and any other Loan Document executed by the Banks and shall have all the rights and obligations of a Bank under the Loan Documents, to the same extent as if it were an original party thereto, and no further consent or action by Borrowers, Banks or the Agent shall be required to release the transferor Bank with respect to its Revolving Commitment assigned to such assignee and the transferor Bank shall henceforth be so released. (b) Each Bank shall have the right to grant participations in all or any part of such Bank's Notes and Revolving Commitment hereunder to one or more pension plans, investment funds, financial institutions or other Persons, provided, that: (i) each Bank granting a participation shall retain the right to vote hereunder, and no participant shall be entitled to vote hereunder on decisions requiring consent or approval of Bank or Majority Banks (except as set forth in (iii) below); (ii) in the event any Bank grants a participation hereunder, such Bank's obligations under the Loan Documents shall remain unchanged, such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, such Bank shall remain the holder of any such Note or Notes for all purposes under the Loan Documents, and Agent, each Bank and Borrowers shall be entitled to deal with the Bank granting a participation in the same manner as if no participation had been granted; and (iii) no participant shall ever have any right by reason of its participation to exercise any of the rights of Banks hereunder, except that any Bank may agree with any participant that such Bank will not, without the consent of such participant (which consent may not be unreasonably withheld) consent to any amendment or waiver requiring approval of all Banks. (c) It is understood and agreed that any Bank may provide to assignees and participants and prospective assignees and participants financial information and reports and data concerning Borrowers' properties and operations which was provided to such Bank pursuant to this Agreement. -43- (d) Upon the reasonable request of either Agent or Borrowers, each Bank will identify those to whom it has assigned or participated any part of its Notes and Revolving Commitment, and provide the amounts so assigned or participated. 28. CHOICE OF FORUM: CONSENT TO SERVICE OF PROCESS AND JURISDICTION. THE OBLIGATIONS OF BORROWERS UNDER THE LOAN DOCUMENTS ARE PERFORMABLE IN HARRIS COUNTY, TEXAS. ANY SUIT, ACTION OR PROCEEDING AGAINST THE BORROWERS WITH RESPECT TO THE LOAN DOCUMENTS OR ANY JUDGMENT ENTERED BY ANY COURT IN RESPECT THEREOF, MAY BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS, COUNTY OF HARRIS, OR IN THE UNITED STATES COURTS LOCATED IN HARRIS COUNTY, TEXAS AND THE BORROWERS HEREBY SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF SUCH COURTS FOR THE PURPOSE OF ANY SUCH SUIT, ACTION OR PROCEEDING.

WAIVER OF JURY TRIAL.
