(b) If requested to do so by the Company through the Agent at least ten Euro-Dollar Business Days before the first day of a proposed Interest Period for Euro-Dollar Loans, each Bank will advise the Agent before 10:00 A.M. (Houston time) on the sixth Euro-Dollar Business Day preceding the date of such proposed Interest Period as to whether, if the Company selects a specified duration of nine or twelve months for such Interest Period, such Bank expects that deposits in dollars with a corresponding term will be available to it in the relevant market on the first day of such Interest Period in the amount required to fund its Loan to which such Interest Period would apply. Unless a Bank responds by such time to the effect that it expects such deposits will not be available to it, the Company shall be entitled to select such proposed duration for such Interest Period. SECTION 2.03. Conversions. (a) The Company may on any Euro-Dollar Business Day, upon notice given to the Agent no later than 10:00 a.m. (Houston time) on the third Euro-Dollar Business Day prior to the date of the proposed Conversion and subject to the provisions of Section 2.02 and Article VIII and the other provisions hereof, Convert all -26- 32 Loans comprising one or more Borrowings; provided, that (i) Loans comprising a Borrowing may not be Converted if after giving effect to such Conversion, such Borrowing would be a Euro-Dollar Borrowing and the outstanding principal amount of such Borrowing would be less than $10,000,000 and (ii) no Conversion (other than changing Euro-Dollar Loans into Base Rate Loans) may be made if any Event of Default is then existing. Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Loans to be Converted, (iii) if after giving effect to such Conversion, such Borrowing would be a Euro-Dollar Borrowing, the commencement date and duration of the proposed Interest Period for each Loan comprising such Borrowing, and (iv) the nature of such Conversion (i.e., whether such Conversion is a change of Loans of one Type into another Type, a continuation of Euro-Dollar Loans as such for an additional Interest Period or an election to change an Interest Period). Each such notice shall be irrevocable. (b) If the aggregate unpaid principal amount of Euro-Dollar Loans comprising any Borrowing shall be reduced by payment or prepayment or otherwise, to less than $10,000,000, such Loans shall automatically, on the last day of the then existing Interest Period therefor, Convert into Base Rate Loans. (c) If the Company shall fail to select the duration of any Interest Period for any Euro-Dollar Loans in accordance with the provisions contained in the definition of "Interest Period" in Section 1.01, or if there shall be any Event of Default, such Loans will automatically on the last day of the then existing Interest Period therefor, Convert into Base Rate Loans. SECTION 2.04. Notice to Banks; Funding of Loans. (a) Upon receipt of a Notice of Borrowing, the Agent shall promptly, (by no later than 10:30 A.M. (Houston time) by telephone or facsimile transmission) notify each Bank of the contents thereof and of such Bank's share of such Borrowing and such Notice of Borrowing shall not thereafter be revocable by the Company. (b) Not later than 12:00 Noon (Houston time) on the date of each Borrowing, each Bank shall (except as provided in subsection (c) of this Section) make available its share of such Borrowing, in Federal or other funds immediately available in Houston, to the Agent at its address specified in or pursuant to Section 9.01. Unless the Agent determines that -27- 33 any applicable condition specified in Article III has not been satisfied, the Agent will make the funds so received from the Banks available to the Company at the Agent's aforesaid address. (c) If any Bank makes a new Loan hereunder to the Company on a day on which the Company is to repay all or any part of an outstanding Loan from such Bank, such Bank shall apply the proceeds of its new Loan to make such repayment and only an amount equal to the difference (if any) between the amount being borrowed by the Company and the amount being repaid shall be made available by such Bank to the Agent as provided in subsection (b), or remitted by the Company to the Agent as provided in Section 2.12, as the case may be. (d) Unless the Agent shall have received notice from a Bank prior to the date of any Borrowing that such Bank will not make available to the Agent such Bank's share of such Borrowing, the Agent may assume that such Bank has made such share available to the Agent on the date of such Borrowing in accordance with subsections (b) and (c) of this Section 2.04 and the Agent may, in reliance upon such assumption, make available to the Company on such date a corresponding amount. If and to the extent that such Bank shall not have so made such share available to the Agent, such Bank and the Company severally agree to repay to the Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Company until the date such amount is repaid to the Agent, at (i) in the case of the Company, a rate per annum equal to the higher of the Federal Funds Rate and the interest rate applicable thereto pursuant to Section 2.07 and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Bank's Loan included in such Borrowing for purposes of this Agreement. SECTION 2.05. Notes. (a) The Loans of each Bank to the Company shall be evidenced by a single Note of the Company payable to the order of such Bank for the account of its Applicable Lending Office in an amount equal to the aggregate unpaid principal amount of such Bank's Loans to the Company. (b) Each Bank may, by notice to the Company and the Agent, request that its Loans of a particular Type payable to such Bank (or such lending office, agency or branch of such Bank as such Bank may specify in such request) be evidenced by a separate Note of the Company in an amount equal to the -28- 34 aggregate unpaid principal amount of such Loans. Each such Note shall be in substantially the form of Exhibit A hereto with appropriate modifications to reflect the fact that it evidences solely Loans of the relevant Type. Any Bank that receives multiple Notes pursuant to this Section 2.05(b) agrees that: (1) the aggregate principal amount payable by the Company under such Notes shall never exceed the aggregate principal amount of the Loans owed to such Bank (including, if applicable, the separate lending offices, agencies or branches of such Bank) and (2) the payees of the Notes issued at the request of such Bank shall enjoy no greater rights (voting or otherwise) than such Bank would enjoy in the absence of such request and such payees (including, if applicable, the separate lending offices, agencies or branches of such Bank) shall be considered a single Bank for purposes of this Agreement. Each reference in this Agreement to the "Note" of such Bank shall be deemed to refer to and include any or all of such Notes, as the context may require. (c) Upon receipt of each Bank's Note pursuant to Section 3.01(b), the Agent shall mail or send by private delivery service such Note to such Bank. Each Bank shall record the date, amount and Type of each Loan made by it to the Company and the date and amount of each payment of principal made with respect thereto, and prior to any transfer of its Note shall endorse on the schedule forming a part thereof appropriate notations to evidence the foregoing information with respect to each such Loan then outstanding; provided that the failure of any Bank to make any such recordation or endorsement shall not affect the obligations of any Obligor under any of the Financing Documents. Each Bank is hereby irrevocably authorized by the Company so to endorse any Note and to attach to and make a part of any Note a continuation of any such schedule as and when required. SECTION 2.06. Maturity of Loans. Each Loan shall mature, and the principal amount thereof shall be due and payable, on April 30, 1996. SECTION 2.07. Interest Rates. The Company shall pay interest on the unpaid principal amount of each Loan from the date of such Loan until such principal amount shall be paid in full, at the following rates per annum: (a) If such Loan is a Base Rate Loan, for each day that such Loan is a Base Rate Loan, at a rate per annum equal to the sum of (i) the Base Rate for such day plus (ii) at such times as the Margin Increase Condition exists and the Additional Margin Increase Condition does not exist, 1/8% plus -29- 35 (iii) at such times as the Additional Margin Increase Condition exists, 1/4% plus (iv) at such times as any Event of Default exists, 1%. Such interest shall be payable quarterly on each March 31, June 30, September 30 and December 31 and on the date such Base Rate Loan is Converted or paid in full. Any overdue interest on any Base Rate Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the sum of 1% plus the otherwise applicable rate for such day. (b) If such Loan is a Euro-Dollar Loan, at a rate per annum equal at all times during any Interest Period for such Loan to the sum of (i) 0.6875% plus (ii) the applicable London Interbank Offered Rate plus (iii) at such times as the Margin Increase Condition exists and the Additional Margin Increase Condition does not exist, 1/8% plus (iv) at such times as the Additional Margin Increase Condition exists, 1/4% plus (v) at such times as any Event of Default exists, 1%; provided that any overdue principal of or interest on any Euro-Dollar Loan shall bear interest, payable on demand, for each day from and including the date payment thereof was due to but excluding the date of actual payment, at a rate per annum equal to the sum of 1% plus the higher of (i) the sum of 0.6875% plus the London Interbank Offered Rate applicable to such Loan plus at such times as the Margin Increase Condition exists and the Additional Margin Increase Condition does not exist, 1/8% plus at such times as the Additional Margin Increase Condition exists, 1/4% and (ii) the sum of (1) 0.6875% plus (2) the average (rounded upward, if necessary, to the next higher 1/16 of 1%) of the respective rates per annum at which one day (or, if such amount due remains unpaid more than three Euro-Dollar Business Days, then for such other period of time not longer than three months as the Agent may select) deposits in dollars in an amount approximately equal to such overdue payment due to each of the Reference Banks are offered to such Reference Bank in the London interbank market for the applicable period determined as provided above plus (3) at such times as the Margin Increase Condition exists and the Additional Margin Increase Condition does not exist, 1/8% plus (4) at such times as the Additional Margin Increase Condition exists, 1/4% (or, if the circumstances described in clause (a) or (b) of Section 8.01 shall exist, at a rate per annum equal to the sum of 1% plus the rate applicable to Base Rate Loans for such day). Such interest shall be payable for each Interest Period on the last day thereof and, if such Interest Period is longer than three months, at intervals of three months after the first day thereof. -30- 36 The "London Interbank Offered Rate" applicable to any Interest Period means the arithmetic average (rounded upward, if necessary, to the next higher 1/16 of 1%) of the respective rates per annum at which deposits in dollars are offered to each of the Reference Banks in the London interbank market at approximately 11:00 A.M. (London time) two Euro-Dollar Business Days before the first day of such Interest Period in an amount approximately equal to the principal amount of the Euro-Dollar Loan of such Reference Bank to which such Interest Period is to apply and for a period of time comparable to such Interest Period. (c) The Agent shall determine each interest rate applicable to the Loans hereunder. The Agent shall give prompt notice to the Company and the participating Banks of each rate of interest so determined, and its determination thereof shall be conclusive in the absence of manifest error. Upon request of the Company, the Agent shall furnish to it such information as to its determinations hereunder as the Company may reasonably request. (d) Each Reference Bank agrees to use its best efforts to furnish quotations to the Agent as contemplated by this Section. If any Reference Bank does not furnish a timely quotation, the Agent shall determine the relevant interest rate on the basis of the quotation or quotations furnished by the remaining Reference Bank or Banks or, if none of such quotations is available on a timely basis, the provisions of Section 8.01 shall apply. (e) This Section 2.07 and each other provision in any of the Financing Documents or in any other agreement executed in connection herewith are specifically made subject to Section 2.16. SECTION 2.08. Fees. (a) During the Revolving Credit Period, the Company shall pay to the Agent for the account of the Banks ratably in proportion to their Commitments a commitment fee at a rate per annum equal to 0.1875% on the daily average amount by which the aggregate amount of the Commitments exceed the aggregate outstanding principal amount of the Loans. Such commitment fee shall accrue from and including the Effective Date to but excluding the Termination Date. Additionally, the Company shall pay to the Agent for the account of the Banks ratably a facility fee at a rate per annum equal to 0.1875% on the daily average aggregate outstanding principal amount of the Loans. Such facility fee shall accrue from and including the Effective -31- 37 Date to but excluding the date the Loans shall be repaid in their entirety. (b) Payments. Accrued fees under this Section 2.08 shall be payable quarterly on each March 31, June 30, September 30 and December 31 and upon the date of termination of the Commitments in their entirety (and, if later, the date the Loans shall be repaid in their entirety). SECTION 2.09. Optional Termination or Reduction of Commitments. The Company may, upon at least three Domestic Business Days' notice to the Agent, (i) terminate the Commitments at any time, if no Loans are outstanding at such time and if the Other Credit Agreement Commitments have been terminated or (ii) ratably reduce from time to time by an aggregate amount of $10,000,000 or any larger multiple of $5,000,000 the aggregate amount of the Commitments in excess of the aggregate outstanding principal amount of the Loans, provided that no such reduction shall reduce the aggregate amount of the Commitments below $100,000,000 unless the Other Credit Agreement Commitments have been terminated. SECTION 2.10. Mandatory Termination or Reduction of Commitments. (a) The Commitments shall terminate on the Termination Date. (b) On the fifth Domestic Business Day following any Asset Sale that results in positive Excess Net Sales Proceeds, (i) the Company will deliver to each of the Banks a certificate of the chief financial officer, the chief accounting officer or the treasurer of the Company certifying the amount of such Excess Net Sales Proceeds from such Asset Sale, (ii) the Commitments shall be automatically reduced ratably by an amount equal to (a) 100% of the amount of such Excess Net Sales Proceeds minus (b) the amount by which the Other Credit Agreement Commitments are reduced pursuant to Section 2.10(d) (ii) of the Other Credit Agreement as a result of such Excess Net Sales Proceeds from such Asset Sale, (iii) the Company shall be obligated to repay such principal amount (together with accrued interest thereon) of each Bank's outstanding Loans, if any, as may be necessary so that after such repayment the aggregate outstanding principal amount of such Bank's Loans does not exceed the amount of such Bank's Commitment as then reduced. SECTION 2.11. Optional Prepayments. (a) The Company may, upon at least one Domestic Business Day's notice to the Agent, prepay any Borrowing in whole at any time, or from time to time in part in amounts aggregating $10,000,000 or any larger multiple of $1,000,000, by paying the principal amount to be prepaid together with accrued interest thereon to the date of prepayment, provided that no partial prepayment of -32- 38 a Euro-Dollar Borrowing shall be made if after giving effect thereto the principal amount of such Borrowing would be less than $10,000,000. Each such optional prepayment shall be applied to prepay ratably the Loans of the several Banks included in such Borrowing. (b) Upon receipt of a notice of prepayment pursuant to this Section, the Agent shall promptly notify each Bank of the contents thereof and of such Bank's ratable share (if any) of such prepayment and such notice shall not thereafter be revocable by the Company. SECTION 2.12. General Provisions as to Payments. (a) The Company shall make each payment of principal of, and interest on, the Loans and of fees hereunder, not later than 12:00 Noon (Houston time) on the date when due, in Federal or other funds immediately available in Houston, to the Agent at its address referred to in Section 9.01. The Agent will promptly distribute to each Bank its ratable share of each such payment received by the Agent for the account of the Banks. Whenever any payment of principal of, or interest on, the Base Rate Loans or of fees shall be due on a day which is not a Domestic Business Day, the date for payment thereof shall be extended to the next succeeding Domestic Business Day. Whenever any payment of principal of, or interest on, the Euro-Dollar Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day falls in another calendar month, in which case the date for payment thereof shall be the next preceding Euro-Dollar Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such extended time. (b) Unless the Agent shall have received notice from the Company prior to the date on which any payment is due from the Company to the Banks hereunder that the Company will not make such payment in full, the Agent may assume that the Company has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent that the Company shall not have so made such payment, each Bank shall repay to the Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Agent, at the Federal Funds Rate. SECTION 2.13. Funding Losses. If any Obligor makes any payment of principal with respect to any Euro-Dollar Loan -33- 39 (pursuant to Article II, VI or VIII or otherwise) on any day other than the last day of an Interest Period applicable thereto, or the end of an applicable period fixed pursuant to the proviso to Section 2.07(b), or if the Company fails to borrow any Euro-Dollar Loan after notice has been given to any Bank in accordance with Section 2.04(a), or if any Conversion of any Euro-Dollar Loan occurs on any day other than the last day of an Interest Period applicable thereto, the Company shall reimburse each Bank within 15 days after demand for any resulting loss or expense incurred by it (or by an existing or prospective Participant in the related Loan), including (without limitation) any loss incurred in obtaining, liquidating or employing deposits from third parties, but excluding loss of margin from the period after any such payment or failure to borrow, provided that such Bank shall have delivered to the Company a certificate as to the amount of such loss or expense, which certificate shall be conclusive in the absence of manifest error. SECTION 2.14. Computation of Interest and Fees. Interest based on the Base Rate hereunder shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and paid for the actual number of days elapsed (including the first day but excluding the last day). All other interest and fees shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day). SECTION 2.15. Chapter 15. In no event shall the provisions of Article 5069, Chapter 15 of the Revised Civil Statutes of Texas (which regulates certain revolving credit loan accounts and revolving tri-party accounts) apply to any Loan made hereunder. SECTION 2.16. Maximum Interest Rate. (a) Nothing contained in this Agreement or the Notes shall require the Company to pay interest at a rate exceeding the maximum rate permitted without penalty by applicable law. Each provision in the Financing Documents and any other agreement executed in connection herewith is expressly limited so that in no event whatsoever shall the amount paid thereunder, or otherwise paid, by the Company for the use, forbearance or detention of the money to be loaned under this Agreement, exceed that amount of money which would cause the effective rate of interest thereon to exceed the maximum rate of interest permitted without penalty under applicable law, and all amounts payable under the Financing Documents or any other agreement executed in connection herewith, or otherwise payable in connection therewith, shall be subject to reduction so that such amounts paid or payable for the use, forbearance or detention of money to be loaned under this Agreement shall not exceed that amount of money which would cause the -34- 40 effective rate of interest thereon to exceed the maximum rate of interest permitted without penalty under applicable law. (b) If the amount of interest payable for the account of any Bank on any interest payment date in respect of the immediately preceding interest computation period, computed pursuant to Section 2.07, would exceed the maximum amount permitted without penalty by applicable law to be charged by such Bank, the amount of interest payable for its account on such interest payment date shall be automatically reduced to such maximum permissible amount. (c) If the amount of interest payable for the account of any Bank in respect of any interest computation period is reduced pursuant to clause (b) of this Section and the amount of interest payable for its account in respect of any subsequent interest computation period, computed pursuant to Section 2.07, would be less than the maximum amount permitted without penalty by applicable law to be charged by such Bank, then the amount of interest payable for its account in respect of such subsequent interest computation period shall be automatically increased to such maximum permissible amount; provided that at no time shall the aggregate amount by which interest paid for the account of any Bank has been increased pursuant to this clause (c) exceed the aggregate amount by which interest paid for its account has theretofore been reduced pursuant to clause (b) of this Section. (d) In the event that maturity of the Loans is accelerated for any reason, or in the event of any required or permitted prepayment of the Loans, then such consideration that constitutes interest payable for the account of any Bank shall never include more than the maximum amount allowed without penalty by applicable law to be charged by such Bank and excess interest, if any, payable for the account of such Bank pursuant to its Note, this Agreement or otherwise shall be cancelled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the Loans of such Bank (or, to the extent in excess of such Loans, refunded by such Bank to the Company). (e) It is further agreed that, without limitation of the foregoing, all calculations of the rate of interest contracted for, charged or received for the account of any Bank under the Note held by it, under this Agreement, under any other agreement executed in connection herewith or otherwise in connection with the Loans or the Commitment of such Bank for the purpose of determining whether such rate exceeds the maximum nonusurious interest rate applicable to such Bank, shall be made, to the extent permitted by usury laws applicable to such Bank (now or hereafter enacted), by amortizing, prorating and spreading in equal parts during the -35- 41 period of the full stated terms of the Loans evidenced by such Note all interest at any time contracted for, charged or received by such Bank in connection therewith. (f) To the extent that any Bank may be subject to Texas law limiting the amount of interest payable for its account, such Bank shall utilize the indicated (weekly) rate ceiling from time to time in effect as provided in Article 5069-1.04 of the Revised Civil Statutes of Texas, as amended. SECTION 2.17. Taxes. (a) Any and all payments by the Company hereunder or under the Notes shall be made, in accordance with Section 2.12, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges and withholdings, and all liabilities with respect thereto, excluding (i) in the case of the Agent, each Co- Agent and each Bank, United States federal income taxes and, without duplication, any taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction under the laws of which the Agent, such Co-Agent or such Bank, as the case may be, is organized or any political subdivision thereof and (ii) in the case of each Bank, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction of such Bank's Applicable Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes"). If the Company shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note to any Bank, any Co-Agent or the Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.17) such Bank, such Co-Agent or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Company shall make such deductions and (iii) the Company shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law. (b) In addition, the Company agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, assessments, charges or similar levies which arise from any payment made hereunder or under the Notes or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, any of the Notes or the Subsidiary Guaranty Agreement (hereinafter referred to as "Other Taxes"). (c) The Company will indemnify each Bank, each Co-Agent and the Agent for the full amount of Taxes and Other Taxes -36- 42 (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.17) paid by such Bank, such Co-Agent or the Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. Payments under any indemnification provided for in this Section 2.17(c) shall be made within 30 days from the date such Bank, such Co-Agent or the Agent (as the case may be) makes written demand therefor. (d) Within 30 days after the date of any payment of Taxes, the Company will furnish to the Agent, at its address referred to in Section 9.01, the original or a certified copy of a receipt evidencing payment thereof. Should any Bank, any Co-Agent or the Agent ever receive any refund, credit or deduction from any taxing authority to which such Bank, such Co-Agent or the Agent, as the case may be, would not be entitled but for the payment by the Company of Taxes as required by this Section 2.17 (it being understood that the decision as to whether or not to claim, and if claimed, as to the amount of any such refund, credit or deduction shall be made by such Bank, such Co-Agent or the Agent, as the case may be, in its sole discretion), such Bank, such Co-Agent or the Agent, as the case may be, thereupon shall repay to the Company an amount with respect to such refund, credit or deduction equal to any net reduction in taxes actually obtained by such Bank, such Co-Agent or the Agent, as the case may be, and reasonably determined by such Bank, such Co-Agent or the Agent, as the case may be, to be attributable to such refund, credit or deduction. (e) Each Bank represents that it is either (i) a corporation, association or other entity organized under the laws of the United States or any state thereof or (ii) entitled to complete exemption from United States withholding tax imposed on or with respect to any payments, including fees, to be made to it pursuant to this Agreement or the Notes. Each Bank that is not organized under the laws of the United States or any state thereof (a "Foreign Bank") agrees to provide to the Company and the Agent, on or prior to the date of this Agreement in the case of each Foreign Bank signatory hereto, and on the date of the Assignment pursuant to which it became a Bank in the case of each other Foreign Bank, two duly completed copies of United States Internal Revenue Service Form 1001 or 4224, certifying in either case that such Foreign Bank is entitled to receive payments from the Company under this Agreement and the Notes without deduction or withholding of any United States federal income taxes. Each Foreign Bank which so delivers a Form 1001 or 4224 further undertakes to deliver to each of the Company and -37- 43 the Agent two additional copies of such form (or a successor form) on or before the date that such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by the Company or the Agent, in each case certifying that such Foreign Bank is entitled to receive payments from the Company under this Agreement and the Notes without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Foreign Bank from duly completing and delivering any such form with respect to it and such Foreign Bank advises the Company and the Agent that it is not capable of receiving such payments without any deduction or withholding of United States federal income tax. Each Bank agrees to indemnify and hold the Company and the Agent harmless from any United States taxes, penalties, interest and other expenses, costs and losses incurred or payable by them as a result of either (a) such Bank's failure to submit any form that it is required to provide pursuant to this Section 2.17(e) or (b) the Agent's and the Company's reliance on any such form which such Bank has provided to them, or on the representation of such Bank made to them pursuant to this Section 2.17(e). (f) If any Taxes are paid by the Company pursuant to this Section 2.17 in respect of the Applicable Lending Office of any Bank, such Bank will, if requested to do so by the Company, designate a different Applicable Lending Office if such designation will avoid the need to pay, or reduce the amount of, such Taxes and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank.

SECTION 4.03. Binding Effect. This Agreement and each of the Notes have been duly executed and delivered by the Company and constitute legal, valid and binding agreements of the Company, and the Subsidiary Guaranty Agreement has been duly executed and delivered by each Required Guarantor and constitutes a legal, valid and binding obligation of each Required Guarantor. SECTION 4.04. Information. (a) The consolidated balance sheet of the Company and its Consolidated Subsidiaries as of December 31, 1993 and the related consolidated statements of operations, cash flows and common stock and other shareholders' equity for the fiscal year then ended, reported on by Price Waterhouse and set forth in the Company's 1993 Form 10-K, a copy of which has been delivered to each of the Banks, fairly present, in conformity with generally accepted accounting principles, the consolidated financial position of the Company and its Consolidated Subsidiaries as of such date and their consolidated results of operations and cash flows for such fiscal year. (b) To the best knowledge of the Company, there are no statements or conclusions in any Engineering Report delivered pursuant hereto which are based upon or include -41- 47 misleading information or fail to take into account material information regarding the matters reported therein, it being understood that such statements and conclusions are necessarily based upon professional opinions, estimates and forecasts, and the Company does not warrant that such opinions, estimates and forecasts will ultimately prove to the have been accurate. (c) The Company's 1993 Form 10-K does not contain any untrue statement of material fact or omit to state a material fact necessary in order to make the statements contained therein not misleading. Except for matters of general public knowledge with respect to the oil and gas industry, the Company has disclosed to the Banks in writing any and all facts which materially and adversely affect or may be reasonably expected so to affect (to the extent the Company can now reasonably foresee), the business, assets, operations, prospects or condition, financial or otherwise, of the Company and its Subsidiaries or the ability of any Obligor to perform its obligations under the Financing Documents. (d) Since December 31, 1993 there has been no material adverse change in the business, financial position, results of operations or prospects of the Company and its Subsidiaries, taken as a whole. (e) No Default exists. SECTION 4.05. Litigation. There is no action, suit or proceeding pending against, or to the knowledge of the Company threatened against or affecting, the Company or any of its Subsidiaries or any of their respective properties or interests at law or in admiralty or equity, before any court or arbitrator or any governmental body, agency or official, foreign or domestic, in which there is a reasonable possibility of an adverse decision which could materially adversely affect the business, financial position or results of operations of the Company and its Subsidiaries, taken as a whole, or which in any manner draws into question the validity of any Financing Document. SECTION 4.06. Compliance with ERISA. Each member of the ERISA Group has fulfilled its obligations under the minimum funding standards of ERISA and the Internal Revenue Code with respect to each Plan and is in compliance in all material respects with the presently applicable provisions of ERISA and the Internal Revenue Code with respect to each Plan.

SECTION 4.07. Environmental Matters. In the ordinary course of its business, the Company conducts an ongoing review of the effect of existing Environmental Laws on the business, operations and properties of the Company and the Subsidiaries, in the course of which it attempts to identify and evaluate associated liabilities and costs (including, without limitation, any capital or operating expenditures required for clean-up or closure of properties presently or previously owned, any capital or operating expenditures required to achieve or maintain compliance with environmental protection standards imposed by law or as a condition of any license, permit or contract, any related constraints on operating activities, including any periodic or permanent shutdown of any facility or reduction in the level of or change in the nature of operations conducted thereat and any actual or potential liabilities to third parties, including employees, and any related costs and expenses). On the basis of this review, the Company has reasonably concluded that existing Environmental Laws are unlikely to have a material adverse effect on the business, financial condition, results of operations or prospects of the Company and its Subsidiaries, taken as a whole. SECTION 4.08. Subsidiaries. All Restricted Assets are owned as of the date of this Agreement by the Company and the Persons listed in Part B of Schedule II hereto or, in the case of Restricted Assets sold since December 31, 1993, by Persons other than Unrestricted Subsidiaries. The list of entities under the caption "Subsidiary Guarantors" on the signature pages of the Subsidiary Guaranty Agreement constitutes a true, complete and accurate list of all Required Guarantors as of the date of this Agreement. Part A of Schedule II hereto contains a true, complete and accurate list of all Unrestricted Subsidiaries, and Part B of Schedule II hereto contains a true, complete and accurate list of all Restricted Subsidiaries as of the date of this Agreement. SECTION 4.09. Ownership of Restricted Subsidiaries. The Company or a Restricted Subsidiary is the record and beneficial owner, free and clear of all Liens (other than those permitted by Section 5.07), of (i) all of the issued and outstanding capital stock (other than directors' qualifying shares and shares beneficially owned by the Company or a -43- 49 Restricted Subsidiary and held by nominees of the Company or a Restricted Subsidiary solely to satisfy requirements of local law) and other ownership interests of each Restricted Subsidiary (except Unimar and the Unimar Restricted Subsidiaries and any other Restricted Subsidiary the capital stock of which is sold pursuant to a sale permitted by Section 5.14) and (ii) except during any period during which Unimar is an Unrestricted Subsidiary or ceases to be a Subsidiary, at least 50% of the ownership interest in Unimar and the Unimar Restricted Subsidiaries.

SECTION 4.11. Taxes and Other Obligations. Consolidated United States Federal income tax returns of the Company and the Subsidiaries have been examined by the Internal Revenue Service, or the statutory period for such examination has expired, for all years up to and including the year ended December 31, 1989, and all assessed deficiencies resulting from such examination have been discharged or reserved against as required by generally accepted accounting principles. The Company and the Subsidiaries have filed all United States Federal, state and local income tax returns and all other material domestic tax returns which are required to be filed by them and have paid, or provided for the payment before the same became delinquent of, all taxes due pursuant to such returns or pursuant to any assessment received by the Company or any Subsidiary, other than those taxes being diligently contested in good faith by appropriate proceedings. The charges, accruals and reserves on the books of the Company and the Subsidiaries in respect of taxes are, in the opinion of the Company, adequate. The Company and the Subsidiaries have set up such reserves as are required by generally accepted accounting principles for the payment of additional taxes for years which have not been audited by the respective tax authorities. The Company and the Subsidiaries have paid all other material obligations when due other than those being contested in good faith by appropriate proceedings. SECTION 4.12. Regulation U.

SECTION 4.13. Certain Obligations. Neither the Company nor any Subsidiary has any obligation to make payments on the Joint Venture Debt other than those permitted by Section 5.17.

If on or prior to the first day of any Interest Period: (a) the Agent is advised by the Reference Banks that deposits in dollars (in the applicable amounts) are not being offered to the Reference Banks in the relevant market for such Interest Period, or -63- 69 (b) Banks having 50% or more of the aggregate amount of the Commitments advise the Agent that the London Interbank Offered Rate as determined by the Agent will not adequately and fairly reflect the cost to such Banks of funding their Euro-Dollar Loans for such Interest Period, the Agent shall forthwith give notice thereof to the Company and the Banks, whereupon until the Agent notifies the Company that the circumstances giving rise to such suspension no longer exist, (i) the obligations of the Banks to make Euro-Dollar Loans, or make any Conversion (other than changing Euro-Dollar Loans into Base Rate Loans), shall be suspended, and (ii) unless the Company notifies the Agent at least two Domestic Business Days before the date of any Euro-Dollar Borrowing for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, such Borrowing shall instead be made as a Base Rate Borrowing. SECTION 8.02. Illegality. If, after the date of this Agreement, the adoption of any applicable law, rule or regulation, or any change therein, 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 (or its Euro-Dollar Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for any Bank (or its Euro-Dollar Lending Office) to make, maintain or fund its Euro-Dollar Loans, or make any Conversion (other than changing Euro-Dollar Loans into Base Rate Loans), and such Bank shall so notify the Agent, the Agent shall forthwith give notice thereof to the other Banks and the Company, whereupon until such Bank notifies the Company and the Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Bank to make Euro-Dollar Loans, or make any Conversion (other than changing Euro-Dollar Loans into Base Rate Loans), as the case may be, shall be suspended. Before giving any notice to the Agent pursuant to this Section, such Bank shall designate a different Euro-Dollar Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank. If such Bank shall determine that it may not lawfully continue to maintain and fund any of its outstanding Euro-Dollar Loans to maturity and shall so specify in such notice, each such Euro-Dollar Loan shall be immediately and automatically Converted into a Base Rate Loan (on which interest and principal shall be payable -64- 70 contemporaneously with the related Euro-Dollar Loans of the other Banks). SECTION 8.03. Increased Cost and Reduced Return. (a) If after the date hereof, the adoption of any applicable law, rule or regulation, or any change therein, 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 (or its Applicable Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (i) shall subject any Bank (or its Applicable Lending Office) to any tax, duty or other charge with respect to its Euro-Dollar Loans, its Note or its obligation to make Euro-Dollar Loans, or shall change the basis of taxation of payments to any Bank (or its Applicable Lending Office) of the principal of or interest on its Euro-Dollar Loans or any other amounts due under this Agreement in respect of its Euro-Dollar Loans or its obligation to make Euro-Dollar Loans (except for changes in the rate of tax on the overall net income of such Bank or its Applicable Lending Office imposed by the jurisdiction in which such Bank's principal executive office or Applicable Lending Office is located); or (ii) shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System against assets of, deposits with or for the account of, or credit extended by, any Bank (or its Applicable Lending Office) or on the United States market for certificates of deposit or the London interbank market any other condition affecting its Euro-Dollar Loans, its Note or its obligation to make Euro-Dollar Loans; and the result of any of the foregoing is to increase the cost to such Bank (or its Applicable Lending Office) of making or maintaining any Euro-Dollar Loan or making any Conversion (other than changing Euro-Dollar Loans into Base Rate Loans), or to reduce the amount of any sum received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or under its Note with respect thereto, by an amount deemed by such Bank to be material, then, within 15 days after -65- 71 demand by such Bank (with a copy to the Agent), the Company shall pay to such Bank such additional amount or amounts as will compensate such Bank for such increased cost or reduction; provided that the Company shall not be obligated to compensate any Bank for any such reduction attributable to a period (i) more than 90 days prior to the giving of notice by such Bank to the Company of its intention to seek compensation under this subsection (a) or (ii) more than six months prior to the making of demand by such Bank for payment thereof in accordance herewith. (b) If any Bank shall have determined that the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change therein, 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 any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on capital of such Bank (or its Parent) as a consequence of such Bank's obligations hereunder to a level below that which such Bank (or its Parent) could have achieved but for such adoption, change, request or directive (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Bank to be material, then from time to time, within 15 days after demand by such Bank (with a copy to the Agent), the Company shall pay to such Bank such additional amount or amounts as will compensate such Bank (or its Parent) for such reduction; provided that the Company shall not be obligated to compensate any Bank for any such reduction attributable to a period (i) more than 90 days prior to the giving of notice by such Bank to the Company of its intention to seek compensation under this subsection (b) or (ii) more than six months prior to the making of demand by such Bank for payment thereof in accordance therewith. (c) Each Bank will promptly notify the Company and the 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 and will designate a different Applicable Lending Office 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 such Bank. A certificate of any Bank claiming compensation under this Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, such Bank may use any reasonable averaging and attribution methods. -66- 72 SECTION 8.04. Base Rate Loans Substituted for Affected Euro-Dollar Loans. If (i) the obligation of any Bank to make Euro-Dollar Loans to the Company has been suspended pursuant to Section 8.02 or (ii) any Bank has demanded compensation under Section 8.03(a) and the Company shall, by at least five Euro-Dollar Business Days' prior notice to such Bank through the Agent, have elected that the provisions of this Section shall apply to such Bank, then, unless and until such Bank notifies the Company that the circumstances giving rise to such suspension or demand for compensation no longer apply: (a) all Loans to the Company which would otherwise be made by such Bank as, or be Converted by such Bank as or into, Euro-Dollar Loans shall instead be made as, or Converted into, Base Rate Loans (on which interest and principal shall be payable contemporaneously with the related Euro-Dollar Loans of the other Banks), and (b) after each of its Euro-Dollar Loans to the Company has been repaid, all payments of principal which would otherwise be applied to repay such Euro-Dollar Loans shall be applied to repay its Base Rate Loans instead. SECTION 8.05. Substitution of Bank. If (i) the obligation of any Bank to make Euro-Dollar Loans has been suspended pursuant to Section 8.02, (ii) any Bank has demanded compensation under Section 8.03 or payment of Taxes or Other Taxes under Section 2.17, or (iii) after satisfaction of all applicable conditions precedent, any Bank fails to fund when due any Loan it is obligated to fund under this Agreement, the Company shall have the right, with the assistance of the Agent, to seek a mutually satisfactory substitute bank or banks (which may be one or more of the Banks) to purchase the Notes and assume the Commitment of such Bank (any such Bank is herein called an "Affected Bank"). Each Affected Bank agrees to sell, without recourse, all of its Commitment, its interest in this Agreement and its Note to any such bank for an amount equal to the sum of the outstanding unpaid principal of and accrued interest on the Loans of such Affected Bank and all commitment fees and other fees and amounts due such Affected Bank hereunder, calculated, in each case, to the date such Commitment, interest in this Agreement and Note are purchased. ARTICLE IX MISCELLANEOUS SECTION 9.01. Notices.

SECTION 9.02. No Waivers. No failure or delay by the Agent or any Bank in exercising any right, power or privilege under any Financing Document 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, power or privilege. The rights and remedies provided in the Financing Documents shall be cumulative and not exclusive of any rights or remedies provided by law. SECTION 9.03. Expenses; Indemnification. (a) The Company shall pay (i) all reasonable documented out-of-pocket costs and expenses of the Agent and the Arranger incurred in connection with the syndication of this Agreement or the preparation of the Financing Documents, any waiver or consent thereunder or any amendment thereof or any Default or alleged Default hereunder and (ii) if an Event of Default occurs, all reasonable out-of-pocket costs and expenses incurred by the Agent or incurred by any Bank, including fees and disbursements of counsel, in connection with such Event of Default and collection and other enforcement proceedings resulting therefrom. (b) The Company agrees to indemnify the Agent, each Co-Agent, the Arranger and each Bank and hold the Agent, each Co-Agent, the Arranger and each Bank harmless from and against any and all liabilities, losses, damages, costs and expenses of any kind (including, without limitation, the reasonable fees and disbursements of counsel for the Agent, any Co-Agent, the Arranger or any Bank in connection with any investigative, -68- 74 administrative or judicial proceedings, whether or not the Agent, such Co-Agent, the Arranger or such Bank, as the case may be, shall be designated a party thereto) which may be incurred by the Agent, any Co-Agent, the Arranger or any Bank, relating to or arising out of this Agreement or any actual or proposed use of proceeds of Loans hereunder, including specifically, without limitation, all liabilities, losses, damages, costs and expenses arising out of a violation of any Environmental Law; provided, that neither the Agent nor any Co-Agent nor the Arranger nor any Bank shall have the right to be indemnified hereunder for its own gross negligence or willful misconduct as determined by a court of competent jurisdiction (IT BEING EXPRESSLY UNDERSTOOD AND AGREED THAT, EXCEPT FOR SUCH NEGLIGENCE AS IS SO DETERMINED TO CONSTITUTE GROSS NEGLIGENCE, SUCH INDEMNIFICATION DOES EXTEND TO THE CONSEQUENCES OF THE ORDINARY NEGLIGENCE, WHETHER SOLE OR CONTRIBUTORY, OF THE INDEMNITEE). (c) Within a reasonable period of time after any Person entitled to indemnification under Section 9.03(b) (an "Indemnified Person") receives actual notice of the assertion of any claim or the commencement of any action, or any threatened claim or action, covered by Section 9.03(b), such Indemnified Person shall, if indemnification with respect thereof is to be sought from the Company under Section 9.03(b), notify the Company in writing of such claim or action; provided that the failure to so notify the Company shall not relieve the Company from any liability which the Company may have to the Indemnified Person under Section 9.03(b) unless the obligations of the Company under Section 9.03(b) have been significantly increased as a result of such failure. The Company and such Indemnified Person shall cooperate in the defense of any such claim or action and shall take those actions reasonably within their power to take which are necessary to preserve any legal defenses to such matters. If any such claim or action shall be brought or threatened against an Indemnified Person, so long as no Event of Default exists, the Company shall be entitled to participate in the defense thereof, and, with the consent of such Indemnified Person, to assume the defense thereof with counsel reasonably satisfactory to the Indemnified Person. Notwithstanding any provision hereof to the contrary, no consent order or settlement shall be entered into in any such claim or action unless both the Company and such Indemnified Person have given their prior written consent thereto, provided that such consent of the Company shall not be required if any Event of Default exists. (d) All obligations of the Company to indemnify or otherwise to make payments to the Agent, any Co-Agent, the Arranger or any Bank provided in this Agreement shall survive -69- 75 any termination of the Commitments and the repayment of the Loans. SECTION 9.04. Sharing of Set-Offs, Etc. Each Bank agrees that if it shall, by exercising any right of set-off or counterclaim or otherwise, receive payment of a proportion of the aggregate amount of principal and interest due with respect to any Note held by it which is greater than the proportion received by any other Bank in respect of the aggregate amount of principal and interest due with respect to any Note held by such other Bank, the Bank receiving such proportionately greater payment shall purchase such participations in the Notes held by the other Banks, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to the Notes held by the Banks shall be shared by the Banks pro rata; provided that nothing in this Section shall impair the right of any Bank to exercise any right of set-off or counterclaim it may have and to apply the amount subject to such exercise to the payment of indebtedness of the Company other than its indebtedness under the Notes. The Company agrees, to the fullest extent it may effectively do so under applicable law, that any holder of a participation in a Note, whether or not acquired pursuant to the foregoing arrangements, may exercise rights of set-off or counterclaim and other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of the Company in the amount of such participation. SECTION 9.05. Amendments and Waivers. Any provision of this Agreement or the Notes may be amended or waived, if, but only if, such amendment or waiver is in writing and is signed by the Company and the Required Banks (and, if the rights or duties of the Agent are affected thereby, by the Agent); provided that no such amendment or waiver shall, unless signed by all the Banks, (i) increase or decrease the Commitment of any Bank or subject any Bank to any additional obligation, (ii) reduce the principal of or rate of interest on any Loan or any fees hereunder, (iii) postpone the date fixed for any payment of principal of or interest on any Loan or any fees hereunder or for any reduction or termination of any Commitment, or (iv) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Notes, or the number of Banks, which shall be required for the Banks or any of them to take any action under this Section or any other provision of this Agreement; provided further that no such amendment or waiver shall amend or waive Section 5.05(a) or any of the definitions relevant to Section 5.05(a) unless signed by Banks having at least 66-2/3% of the aggregate amount of the Commitments or, if the Commitments shall have been terminated, holding Notes evidencing at least 66-2/3% of the aggregate unpaid principal amount of the Loans. -70- 76 SECTION 9.06. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that the Company may not assign or otherwise transfer any of its rights under this Agreement without the prior written consent of all Banks. (b) Any Bank may at any time and from time to time grant to one or more banks or other institutions (each a "Participant") participating interests in its Commitment or any or all of its Loans. In the event of any such grant by a Bank of a participating interest to a Participant, whether or not upon notice to the Company and the Agent, such Bank shall remain responsible for the performance of its obligations hereunder, and the Company and the Agent shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations under this Agreement. Any agreement pursuant to which any Bank may grant such a participating interest shall provide that such Bank shall retain the sole right and responsibility to enforce the obligations of the Company hereunder including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement; provided that such participation agreement may provide that such Bank will not agree to any modification, amendment or waiver of this Agreement described in clause (i), (ii) or (iii) of Section 9.05 without the consent of the Participant. The Company agrees that each Participant shall, to the extent provided in its participation agreement, be entitled to the benefits of Article VIII with respect to its participating interest. An assignment or other transfer which is not permitted by subsection (c) or (d) below shall be given effect for purposes of this Agreement only to the extent of a participating interest granted in accordance with this subsection (b). (c) Any Bank may at any time assign to one or more banks or other institutions (each an "Assignee") a proportionate part of all of its rights and obligations under this Agreement and the Notes in an amount which, when added to the amount of the rights and obligations under the Other Credit Agreement contemporaneously assigned by such transferor Bank to such Assignee pursuant to the second proviso to the first sentence of Section 9.06(c) of the Other Credit Agreement, equals $10,000,000 or more, and such Assignee shall assume such rights and obligations under this Agreement and the Notes, pursuant to an Assignment executed by such Assignee and such transferor Bank, with (and subject to) the subscribed consent of the Company and the Agent (which such consents shall not be unreasonably withheld); provided that if an Assignee is an affiliate of such transferor Bank or is another Bank, no such consent of the Company shall be required; provided further that each such assignment shall be of a -71- 77 constant, and not a varying, percentage of all rights and obligations under this Agreement and the Notes, and the same constant percentage of all rights and obligations of such transferor Bank under the Other Credit Agreement and the notes thereunder shall be contemporaneously assigned by such transferor Bank to such Assignee pursuant to Section 9.06(c) of the Other Credit Agreement. Upon execution and delivery of such instrument (and delivery to the Agent of an Administrative Questionnaire with respect to such Assignee, if such Assignee has not already done so) and payment by such Assignee to such transferor Bank of an amount equal to the purchase price agreed between such transferor Bank and such Assignee, such Assignee shall be a Bank party to this Agreement and shall have all the rights and obligations of a Bank with a Commitment as set forth in such instrument of assumption, and the transferor Bank shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be required. Upon the consummation of any assignment pursuant to this subsection (c), the transferor Bank, the Agent and the Company shall make appropriate arrangements so that, if required, a new Note is issued to the Assignee. In connection with any such assignment, the transferor Bank shall pay to the Agent for its account an administrative fee for processing such assignment in the amount of $2,500 less any administrative processing fee paid to the Agent on the same date under Section 9.06(c) of the Other Credit Agreement as a result of the contemporaneous assignment to such Assignee by such transferor Bank under the Other Credit Agreement pursuant to the second proviso to the first sentence of this Section 9.06(c). If the Assignee is not incorporated under the laws of the United States of America or a state thereof, it shall, prior to the first date on which interest or fees are payable hereunder for its account, deliver to the Company and the Agent certification as to exemption from deduction or withholding of any United States federal income taxes in accordance with Section 2.17. Notwithstanding the first sentence of this subsection (c), a Bank may not make an assignment pursuant to this subsection (c) if after giving effect thereto such Bank would hold less than 1.5% (or until May 1, 1996, 3% in the case of NationsBank, Bank of America National Trust and Savings Association and Union Bank of Switzerland, Houston Agency) of the Commitments (for this purpose such Bank shall be deemed to hold any participating interests granted by such Bank pursuant to subsection (b) above and any rights assigned pursuant to subsection (d) below). (d) Any Bank may at any time assign all or any portion of its rights under this Agreement and its Note to a Federal Reserve Bank. No such assignment shall release the transferor Bank from its obligations hereunder. -72- 78 (e) No Assignee, Participant or other transferee of any Bank's rights shall be entitled to receive any greater payment under Section 8.03 than such Bank would have been entitled to receive with respect to the rights transferred, unless such transfer is made with the Company's prior written consent or by reason of the provisions of Section 8.02 or 8.03 requiring such Bank to designate a different Applicable Lending Office under certain circumstances or at a time when the circumstances giving rise to such greater payment did not exist. SECTION 9.07. Collateral. Each of the Banks represents to each Agent and each of the other Banks that it in good faith is not relying upon any margin stock (as defined in Regulation G) or any margin stock (as defined in Regulation U) as collateral in the extension or maintenance of the credit provided for in this Agreement.

SECTION 9.10. Counterparts. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. SECTION 9.11. WAIVER OF JURY TRIAL.
