Principal shall be payable on the Termination Date; provided, however, in the event at any time the aggregate outstanding principal amounts of the Revolving Loans to the Borrower, when added to the aggregate unfunded amounts of Credits at such time outstanding to the Borrower, causes its Borrowing Base Amount to be exceeded, the Borrower shall immediately upon demand by the Bank prepay its Revolving Note in an amount necessary to cause the aggregate principal amount of its unpaid Revolving Loans plus the aggregate unfunded amount of its Credits to equal its Borrowing Base Amount (or, at the option of the Bank, the Borrower may post cash collateral to secure such deficiency in its Borrowing Base Amount). The Borrower hereby authorizes the Bank to debit the Dominion Account to pay interest due on the Revolving Note on each Interest Payment Date, and to credit all proceeds of the Receivables received in the Dominion Account when collected (or earlier, if the Bank in its sole discretion allows such funds to be available to the Borrower prior to the date on which any checks or other instruments given in payment of Receivables are actually collected) towards payment of the Revolving Loans outstanding under the Revolving Note. Further, in the event there is no outstanding debt under the Revolving Note, the Borrower authorizes the Bank to sweep daily the proceeds from the Dominion Account into the Borrower's operating account with Bank. The Bank agrees to give notice to the Borrower of any debits to the said funding account used to pay interest within three (3) Business Days following each such debit. Section 2.2.5. Reserved Section 2.2.6. Proceeds of Dominion Account. The Borrower has executed a lockbox agreement with the Bank, pursuant to which all checks, drafts and other instruments evidencing payment of the Borrower's Receivables shall be delivered to the Bank and deposited into the Borrower's Dominion Account more fully described in Section 11.14 hereof. The Borrower hereby authorizes the Bank to apply, on a daily basis, the proceeds of all its accounts receivable actually collected (or, at the sole discretion of the Bank, amounts which have been received but not yet collected) by the Bank from the Dominion Account to reduce the outstanding principal balance of the Revolving Loans due. Such payments will adjust availability immediately for purposes of loan availability and on the next day for bookkeeping and interest purposes. Section 2.2.7. Use of Proceeds. The Borrower shall use the proceeds of the Revolving Loan Commitment solely to refinance existing indebtedness incurred by Omni Geophysical and thereafter to finance working capital requirements and general corporate purposes of the Borrower. Section 2.2.8. Overlines and Overadvances. Notwithstanding the provisions of Section 2.2.1 hereof, in the event that at any time the aggregate unpaid principal amount of the Revolving Loans ever exceeds $10,000,000 (the maximum possible amount of the Borrowing Base Amount), the Borrower agrees to pay the excess amount (an "overline") immediately upon demand by the Bank. In the event the unpaid principal amount of the Revolving Loans ever exceeds the Borrowing Base Amount then in effect, the Borrower agrees to pay the excess amount (an "overadvance") immediately upon demand by the Bank. Overlines and overadvances shall bear interest at the rate (or at the highest rate, if more than one rate is then in effect) borne by the Revolving Note. Upon request of the Bank, the Borrower shall execute a promissory note, payable to the order of the Bank, to represent the amount of any overline or overadvance; however, the Borrower acknowledges and agrees that the records of the Bank and this Agreement shall constitute conclusive evidence of any overline or overadvance and the obligation of the Borrower to repay any overline or overadvance, with interest. All overlines and overadvances for which the Bank has not demanded payment earlier, and all unpaid and accrued interest on overlines and overadvances not due and payable earlier, shall be due and payable on the Termination Date. The Borrower acknowledges and agrees that the Bank is not obligated to the Borrower to fund any advance which would create an overline or overadvance. Section 2.3. The Credits. Section 2.3.1. The Credits. Upon the written application of the Borrower, using the form of letter of credit application then normally required by the Bank in connection with the issuance of such Credits (the "Credit Application"), executed by the Borrower (or by any one of the persons designated by the Borrower in writing to the Bank in accordance with the terms hereof), the Bank agrees, subject to the terms and conditions of this Agreement, that it will issue its Credit substantially in accordance with the Credit Application. Credits may either be commercial letters of credit, in which case they shall have an expiry date on a Business Day not later than the earlier to occur of the Termination Date, or standby letters of credit issued to secure workers' compensation obligations of the Borrower (or for other purposes deemed acceptable by the Bank in its sole discretion), in which case they shall have an expiry date not later than the earlier to occur of the Termination Date or one year from the date of issuance. In no event shall a Credit be issued by the Bank for the account of the Borrower (i) if the sum of the face amount thereof when added to the aggregate unfunded amount of Credits issued for the account of the Borrower then outstanding exceeds $1,000,000.00 or (ii) if the sum of the face amount thereof when added to the aggregate unfunded amount of Credits issued for the account of the Borrower then outstanding plus the aggregate principal amount of the Revolving Loans to the Borrower at such time outstanding exceeds the Borrowing Base Amount then in effect. Section 2.3.2. Issuance of Credits. Each Credit shall be issued not later than three (3) Business Days after receipt by the Bank of the Credit Application related thereto. No later than 12:00 noon (Central Time) on the third Business Day following receipt of the Credit Application and upon fulfillment of the applicable conditions set forth in this Agreement, the Bank shall issue its Credit. The Bank may rely fully and completely upon the authority of the signatory of the Credit Application and the contents thereof unless such authority is terminated by written notice delivered to the Bank, and any such termination of authority shall be effective only prospectively. Section 2.3.3. Credit Commission. The Borrower agrees to pay to the Bank the standard fees charged and established by the Bank from time to time for the issuance and processing of letters of credit (the "Credit Commission") with respect to each Credit created by the Bank hereunder. Payment of such Credit Commission with respect to each Credit created by the Bank shall be paid in advance on the date of issuance of the Credit. With respect to standby Credits issued hereunder, the Borrower unconditionally agrees to pay to the Bank, in addition to the Bank's standard fees for the issuance and processing of such Credits, a commission, payable in advance on or before the date of issuance of each Credit, calculated at the rate of 1.50% per annum on the face amount of each Credit, based upon the number of days of the term of each such Credit divided by 360, which commission shall not be less than $300.00 per standby letter of credit. Section 2.3.4. Credit Obligations. The Borrower agrees unconditionally to pay the Bank on demand in United States currency at the Bank's principal office in New Orleans, Louisiana, the amount required to pay (a) any and all drafts drawn and any and all demands made or purported to be made under any Credit issued for its account, (b) any and all costs, charges, fees and/or expenses incurred or paid by the Bank in connection with any Credit issued for its account, and (c) interest on such amounts described above under (a) and (b) as hereinafter provided (the "Credit Obligations"). In the event of any drafts drawn and any and all demands made under any Credit are payable in foreign currency, the Borrower agrees to make the aforementioned payment to the Bank in United States currency at the Bank's selling rate for cable transfers to the place of payment of such draft on the date of such payment. Such obligation of the Borrower shall be deemed a Credit Obligation hereunder. The Borrower further agrees to comply with any and all governmental currency exchange regulations or requirements now or hereafter applicable to such Credit or to any drafts related thereto. The Borrower further authorizes the Bank, at its option, to compensate itself by applying any part or all of the balance of any deposit account or certificate of deposit which the Borrower may maintain with the Bank, at any time, whether or not the deposit is mature, and/or any and all monies or property or interest of any kind now or hereafter in the Bank's hands, or in transit to or from the Bank, and belonging to the Borrower, to the payment, in whole or in part, of the amount of any draft and all interest, costs and attorney's fees which the Borrower may owe the Bank pursuant to this Agreement. In the event a Credit Obligation is not paid when demanded by the Bank, the Borrower agrees to pay to the Bank on demand a sum equal to the amount of the Credit Obligation, plus interest thereon from the date the Credit Obligation is demanded by the Bank until paid at the interest rate then in effect under the Revolving Note. A payment shall not be deemed made until funds therefor have been actually collected and made available to the Bank. Upon the occurrence of an Event of Default hereunder, the Borrower agrees to pay to the Bank on demand a sum equal to the aggregate unfunded amounts of all Credits outstanding, together with interest thereon at the Base Rate, or at any higher rate of interest which the Bank may impose as a default rate pursuant to the terms of the Borrower's Revolving Note issued pursuant to the terms hereof (such obligation of the Borrower shall be deemed a Credit Obligation as such term is used herein). Upon the occurrence of such Event of Default, the Bank may exercise its right of offset and compensation set forth above in this Section 2.3.4. Any amount which the Bank offsets or which the Borrower may pay to the Bank in excess of drafts actually drawn on any outstanding Credits, shall be held by the Bank in pledge to secure the payment of future drafts until the Commitments to the Borrower have been terminated, all Indebtedness of the Borrower has been paid in full, and no further Credits issued for the account of the Borrower are outstanding. Section 2.3.5. Revolving Loans. In the event that Credit Obligations owed the Bank by the Borrower are not paid when due for any reason including Credit Obligations arising upon occurrence of an Event of Default hereunder, notwithstanding the limitation contained in Section 2.2.1, such Credit Obligations shall be immediately paid by the Borrower pursuant to Revolving Loans in the amount of such Credit Obligations. Such Credit Obligations shall be immediately converted to Revolving Loans by the Bank and evidenced by the Revolving Note. If at any time any Event of Default occurs and any portion of any Credits remains unfunded, the Borrower for whose account such Credits were issued shall pay to the Bank in cash for application to future drawings under the outstanding Credits, an amount equal to the aggregate unfunded portion of the outstanding Credits. If the Borrower does not pay such amount on demand, notwithstanding the limitation contained in Section 2.2.1, such amount shall be immediately paid by the Borrower by Revolving Loans to the Borrower from the Bank. Such amount shall be immediately converted to a Revolving Loan by the Bank and shall be evidenced by the Revolving Note. The amount of such Revolving Loans shall be held by the Bank in pledge securing all of the Borrower's obligations under this Agreement, with the Borrower hereby granting the Bank a continuing security interest in such funds as security for the Indebtedness of the Borrower until the Commitments have all terminated, all Indebtedness of the Borrower has been paid in full, and no further Credits issued for the account of the Borrower are outstanding. Section 2.3.6. Hold Harmless. The Bank shall have the right to deliver the Credit through any correspondents or agents (the "Correspondents") that the Bank in its sole discretion may choose. Except in the case of the Bank's gross negligence or willful misconduct, the Borrower shall hold the Bank harmless from any actions that arise out of the handling of such delivery by the Correspondents making the delivery. The Borrower further agrees that the Bank and any Correspondent shall not in any way be responsible for performance by any beneficiary of obligations to the Borrower nor for the form, validity, sufficiency, correctness, truthfulness or genuineness of any documents delivered in connection with any Credit, even if such documents should in fact prove to be in any or all respects invalid, insufficient, fraudulent or forged; for failure of any Credit draft to bear any reference or correct reference to the Credit; for errors, omissions, or delays in transmission or delivery of any messages, whether by mail, cable, teletransmission, or otherwise; or for any error, neglect or default of any Correspondents. The Borrower further agrees that, if any of the above events should occur, such event will not affect, impair or prevent the Borrower's liability or the Bank's rights or powers hereunder. No liability shall attach to the Bank or to the Correspondents for any losses or damage, in consequence of present or future laws, censorships, regulations, decrees, orders or restrictions, right or wrongfully exercised by an de facto or de jure government or governmental agency. Without limiting the foregoing, and in addition to any other provision hereof, the Bank is hereby expressly authorized and directed to honor any request for payment which is made under and in compliance with the terms of the Credit without regard to, and without any duty on the Bank's part to inquire into, the existence of any disputes or controversies between the Borrower and the beneficiary or any other person, firm, or corporation, or the respective rights, duties or liabilities of any of them or whether any facts or occurrences represented in any documents presented under the Credit are true and correct. The Borrower fully understands and agrees that the sole obligation of the Bank to the Borrower shall be limited to honoring requests for payment made under and in compliance with the Credit and the obligation of the Bank remains so limited even if the Bank may have assisted the Borrower in the preparation of the wording of the Credit or any documents required to be presented thereunder or if the Bank may otherwise be aware of the underlying transaction giving rise to the Credit. If the Bank, in its sole discretion and at the written request of the Borrower, agrees to any change or modification to the amount or terms of any Credit or any instrument or document related thereto, the Borrower agrees that this Agreement shall be binding upon it with regard to any changes or modifications and with regard to any actions taken by the Bank or by any agents or Correspondents relative thereto. ARTICLE III ACQUISITION LOANS Section 3.1. The Acquisition Loan Commitment. Subject to the terms and conditions of this Agreement, the Bank agrees to extend credit to the Borrower during the period from the date hereof until January 20, 1999 by making Acquisition Loans to the Borrower from time to time for the account of the Borrower; provided, however, (i) advances under the Acquisition Loan Commitment are subject to a sublimit for geophysical equipment purchases and loan availability limits, all as set forth in the definition of Borrowing Base Amount applicable to the Acquisition Loan Commitment, and (ii) that at no time shall the sum of the aggregate principal amount of Acquisition Loans to the Borrower at such time outstanding exceed the Borrowing Base Amount then in effect. In the event, at any time, and from time to time, the sum of all outstanding Acquisition Loans issued and outstanding to the Borrower exceeds the Borrowing Base Amount then in effect, the Borrower shall prepay the Acquisition Loans by such an amount to cause the sum of the Acquisition Loans outstanding to the Borrower to equal the Borrowing Base Amount (or, at the option of the Bank, the Borrower may post cash collateral to secure such deficiency in the Borrowing Base Amount). The Acquisition Loan Commitment is a non-revolving loan commitment. Section 3.2. Acquisition Loans. Section 3.2.1. Acquisition Note. Subject to the terms and conditions of this Agreement, the Bank agrees to make Acquisition loans to the Borrower from time to time during the period of the date hereof to January 20, 1999, provided however, that (1) no such Acquisition Loan shall exceed an amount which, when added to (i) the aggregate principal amount of all Acquisition Loans to the Borrower at such time outstanding exceeds the Borrowing Base Amount then in effect. The Borrower's obligation to repay the Acquisition Loans made by the Bank shall be evidenced by a master promissory note of the Borrower (said promissory note being herein referred to as the "Acquisition Note"), payable to the order of the Bank in the principal sum of $9,000,000.00 or such other or lesser amount as may be reflected from time to time on the books and records of the Bank as evidencing the aggregate unpaid principal balance of Acquisition Loans made to the Borrower, with a final maturity of January 20, 2000, and bearing interest at the rate or rates from time to time in effect pursuant to the terms of Article VI hereof. Interest on the Acquisition Note shall be payable in accordance with the terms of Section 6.2 hereof. Section 3.2.2. Manner and Notice of Borrowing Under the Acquisition Loan Commitment. Requests For Advances under the Acquisition Loan Commitment may be made by the Borrower in person, in writing (including facsimile transmission) or through telephone calls to the Bank and such requests shall be fully authorized by the Borrower if made by any one of the persons designated by the Borrower in writing to the Bank. The Bank shall have the right, but not the obligation, to verify any telephone requests by calling the person who made the request at the telephone number designated by the Borrower in writing to the Bank. Requests For Advances must be received by not later than 11:00 a.m. (Central Time) on the date of the proposed advance. Not later than the close of business on the date of such request, assuming all conditions of this Agreement for such advance has been satisfied, the Bank will make such advance. The amount thereof shall be credited by the Bank to the checking account maintained in the name of the Borrower with the Bank and the credit advice resulting therefrom shall be mailed to the Borrower. The Bank's copy of such credit advice indicating such deposit to the account of the Borrower shall be deemed conclusive evidence of the Borrower's indebtedness to the Bank in connection with such borrowing. The aggregate outstanding amount of principal and interest due by the Borrower at any given time under the Acquisition Loan Commitment shall be and constitute the indebtedness of the Borrower to the Bank under the Acquisition Note made by the Borrower. When each Acquisition Loan is made by the Bank to the Borrower hereunder, the Borrower shall be deemed to have renewed and reissued its Acquisition Note for the amount of the advance plus all amounts due by the Borrower to the Bank under the Acquisition Loan Commitment immediately prior to such advance. Section 3.2.3. Borrowings Under the Acquisition Loan Commitment. Within the limits of the Acquisition Loan Commitment and subject to the terms and conditions of this Agreement, the Bank shall only be obligated to lend the Borrower an amount which will not cause the Borrowing Base Amount to be exceeded. Section 3.2.4. Payment of the Acquisition Note Under the Acquisition Loan Commitment. Interest on the unpaid principal balance of the Acquisition Note shall be payable quarterly for the first twelve (12) months. Thereafter, principal and interest shall be paid quarterly based on a five (5) year straight line amortization, with a final maturity of January 20, 2000. In the event at any time the aggregate outstanding principal amounts of the Acquisition Loans to the Borrower causes the Borrowing Base Amount to be exceeded, the Borrower shall immediately upon demand by the Bank prepay its Acquisition Note in an amount necessary to cause the aggregate principal amount of its unpaid Acquisition Loans to equal the Borrowing Base Amount (or, at the option of the Bank, the Borrower may post cash collateral to secure such deficiency in its Borrower Base Amount). The Borrower hereby authorizes the Bank to debit the Dominion Account to pay interest due on the Acquisition Note on each Interest Payment Date during the first twelve (12) months. The Bank agrees to give notice to the Borrower of any debits to the said funding account used to pay interest within three (3) Business Days following each such debit. Section 3.2.5. Use of Proceeds. The Borrower shall use the proceeds of the Acquisition Loan Commitment solely to finance capital expenditures and acquisitions. Section 3.2.6. Overlines and Overadvances. Notwithstanding the provisions of Section 3.2.1 hereof, in the event that at any time the aggregate unpaid principal amount of the Acquisition Loans ever exceeds $9,000,000 (the maximum possible amount of the Borrowing Base Amount), the Borrower agrees to pay the excess amount (an "overline") immediately upon demand by the Bank. In the event the unpaid principal amount of the Acquisition Loans ever exceeds the Borrowing Base Amount then in effect, the Borrower agrees to pay the excess amount (an "overadvance") immediately upon demand by the Bank. Overlines and overadvances shall bear interest at the rate (or at the highest rate, if more than one rate is then in effect) borne by the Acquisition Note. Upon request of the Bank, the Borrower shall execute a promissory note, payable to the order of the Bank, to represent the amount of any overline or overadvance; however, the Borrower acknowledges and agrees that the records of the Bank and this Agreement shall constitute conclusive evidence of any overline or overadvance and the obligation of the Borrower to repay any overline or overadvance, with interest. All overlines and overadvances for which the Bank has not demanded payment earlier, and all unpaid and accrued interest on overlines and overadvances not due and payable earlier, shall be due and payable on the Termination Date. The Borrower acknowledges and agrees that the Bank is not obligated to the Borrower to fund any advance which would create an overline or overadvance. ARTICLE IV TERM LOAN Section 4.1. The Term Loan. Subject to the terms, conditions and provisions of this Agreement, the Bank agrees to make a term loan (the "Term Loan") to the Borrower in an amount not to exceed $10,951,810.41 ("Term Loan Commitment"). Section 4.2. The Term Note. The Borrower's indebtedness to the Bank pursuant to the Term Loan shall be evidenced by a promissory note of the Borrower (said promissory note being herein referred to as the "Term Note"), payable to the order of the Bank in the principal sum of the amount of the Term Loan Commitment, with a final maturity of January 20, 2000, and bearing interest at the rate or rates from time to time in effect pursuant to the terms of Article VI hereof the Term Note.

The Borrower hereby authorizes the Bank to debit its account maintained with the Bank for collection of the fee. In addition, the parties have entered into a letter agreement addressing additional commitment fee matters. Section 5.2. Unused Fee. The Borrower shall pay the Bank a fee equal to 0.38% per annum on the unused portion of the Revolving Loan Commitment and the Acquisition Loan Commitment, payable quarterly in arrears, commencing April 20, 1998, and quarterly thereafter, and on the Termination Date. The unused portion of the Revolving Loan Commitment and the Acquisition Loan Commitment shall be determined on a daily basis by subtracting from $19,000,000.00 the amount of all Acquisition Loans, Revolving Loans, and Credits outstanding, and by averaging said daily amounts for the period for which the fee is to be determined. Section 5.3. Stock Option. The provisions of paragraph 3(c)(ii) of the Second Amendment to the First Restated Agreement shall remain in effect. ARTICLE VI INTEREST PAYABLE ON THE LOANS Section 6.1. Interest on the Loans. The unpaid principal amounts of all Loans or Tranches shall bear interest at the LIBOR Rate plus the Applicable Margin then in effect for such Loans as determined by the Bank at the time such LIBOR Rate is determined for any of the Loans or Tranches thereof. Section 6.2. Payment of Interest on the Loans. Interest on all Loans shall be payable on the last Business Day of each quarter and on the final maturity date of each such Loan (each such interest payment date for any Loan being herein referred to as an "Interest Payment Date"). ARTICLE VII CERTAIN GENERAL PROVISIONS Section 7.1. Payments to the Bank. All payments of principal, interest, commitment fees and any other amounts due hereunder or under any of the other Related Documents shall be made to the Bank at the Bank's office at 313 Carondelet Street, New Orleans, Louisiana 70130, or at such other location that the Bank may from time to time designate in writing to the Borrower, in each case in immediately available funds. Section 7.2. No Offset, etc. All payments by the Borrower hereunder and under any of the other Related Documents shall be made without setoff or counterclaim and free and clear of and without deduction for any taxes, levies, imposts, duties, charges, fees, deductions, withholdings, compulsory loans, restrictions or conditions of any nature now or hereafter imposed or levied by any jurisdiction or any political subdivision thereof or taxing or other authority therein unless the Borrower is compelled by law to make such deduction or withholding. If any such obligation is imposed upon the Borrower with respect to any amount payable by it hereunder or under any of the other Loan Documents, the Borrower will pay to the Bank, on the date on which such amount is due and payable hereunder or under such other Related Document, such additional amount in Dollars as shall be necessary to enable the Bank to receive the same net amount which the Bank would have received on such due date had no such obligation been imposed upon the Borrower. The Borrower will deliver promptly to the Bank certificates or other valid vouchers for all taxes or other charges deducted from or paid with respect to payments made by the Borrower hereunder or under such other Loan Documents. Section 7.3. Computations. All computations of interest on the Loans and of commitment or other fees shall be assessed utilizing a 360-day daily interest factor over the number of days in an actual calendar year (365 days or 366 days in a leap year). The Bank shall determine each interest rate applicable to the Loans in accordance with this Agreement, and the Bank's determination of same shall be conclusive in the absence of manifest error. Except as otherwise provided in the definition of the term "Interest Period", whenever a payment hereunder or under any of the other Related Documents becomes due on a day that is not a Business Day, the due date for such payment shall be extended to the next succeeding Business Day, and interest shall accrue during such extension. The outstanding amount of the Loans as reflected on the Bank's books and records from time to time shall be prima facie evidence of the amounts so outstanding. Section 7.4. Inability to Determine LIBOR Rate. In the event, prior to the commencement of any Interest Period, the Bank shall determine or be notified that adequate and reasonable methods do not exist for ascertaining the LIBOR Rate that would otherwise determine the rate of interest to be applicable to the Loans during any Interest Period, the Bank shall forthwith give notice of such determination (which shall be conclusive and binding on the Borrower) to the Borrower. In such event the Loans (or any Tranches thereof) will automatically, on the last day of then current Interest Period applicable to such Loans or Tranches, become a Base Rate Loan until the Bank determines that the circumstances giving rise to such suspension no longer exist, whereupon the Bank shall so notify the Borrower. Section 7.5. Illegality. Notwithstanding any other provisions herein, if any present or future law, regulation, treaty or directive or the interpretation or application thereof shall make it unlawful for the Bank to make available, or maintain in effect, the LIBOR Rate, the Bank shall forthwith give notice of such circumstances to the Borrower and thereupon any Loans bearing interest at a LIBOR Rate shall be converted automatically to Base Rate Loans on the last day of then current Interest Period applicable to such Loans or within such earlier period as may be required by law. The Borrower hereby agree promptly to pay the Bank, upon demand by the Bank, any additional amounts necessary to compensate the Bank for any costs incurred by the Bank in making any conversion in accordance with this paragraph, including any interest or fees payable by the Bank to lenders of funds obtained by it in order to make available, or maintain in effect, the LIBOR Rate for the Loans. Section 7.6. Additional Costs, etc. If any present or future applicable law, which expression, as used herein, includes statutes, rules and regulations thereunder and interpretations thereof by any competent court or by any governmental or other regulatory body or official charged with the administration or the interpretation thereof and requests, directives, instructions and notices at any time or from time to time hereafter made upon or otherwise issued to the Bank by any central bank or other fiscal, monetary or other authority (whether or not having the force of law), shall: (1) subject the Bank to any tax, levy, impost, duty, charge, fee, deduction or withholding of any nature with respect to this Agreement, the other Related Documents or the Indebtedness (other than taxes based upon or measured by the revenue, income or profits of the Bank), or (2) materially change the basis of taxation (except for changes in taxes on revenue, income or profits) of payments to the Bank of the principal of or the interest on the Indebtedness of any other amounts payable to the Bank under this Agreement or the other Related Documents, or (3) impose or increase or render applicable (other than to the extent specifically provided for elsewhere in this Agreement) any special deposit, reserve, assessment, liquidity, capital adequacy or other similar requirements (whether or not having the force of law) against assets held by, or deposits in or for the account of, or loans by, or commitments of an office of the Bank, or (4) impose on the Bank any other conditions or requirements with respect to this Loan Agreement, the other Related Documents, the Indebtedness, or any class of loans of which the Indebtedness forms a part, and the result of any of the foregoing is (i) to increase the cost to the Bank of making, funding, issuing, renewing, extending or maintaining the Indebtedness or issuing Credits, or (ii) to reduce the amount of principal, interest or other amount payable to the Bank hereunder on account of such the Indebtedness, or (iii) to require the Bank to make any payment or to forego any interest or other sum payable hereunder, the amount of which payment or foregone interest or other sum is calculated by reference to the gross amount of any sum receivable or deemed received by the Bank from Borrower hereunder, then, and in each such case, the Borrower will, upon demand made by the Bank at any time and from time to time and as often as the occasion therefor may arise, pay to the Bank such additional amounts as will be sufficient to compensate the Bank for such additional cost, reduction, payment or foregoing interest or others sum. Section 7.7. Capital Adequacy. If after the date hereof the Bank determines that (a) the adoption of or change in any law, governmental rule, regulations, policy guideline or directive (whether or not having the force of law) regarding capital requirements for banks or bank holding companies or any change in the interpretation or application thereof by a court or governmental authority with appropriate jurisdiction, or (b) compliance by the Bank or any corporation controlling the Bank with any law, governmental rule, regulation, policy, guideline or directive (whether or not having the force of law) of any such entity regarding capital adequacy, has the effect of reducing the return on the Bank's Loans to a level below that which the Bank could have achieved but for such adoption, change or compliance (taking into consideration the Bank's then existing policies with respect to capital adequacy and assuming full utilization of such entity's capital) by any amount deemed by the Bank to be material, then the Bank may notify the Borrower of such fact. The Borrower agrees to pay the Bank for the amount of such reduction in the return on capital as and when such reduction is determined upon presentation by the Bank of a certification in accordance with Section 7.8. Section 7.8. Certificate; Optional Right of Prepayment. The Bank shall provide the Borrower with a certificate setting forth any additional amounts which it declares to be payable pursuant to Sections 7.6 and 7.7 hereof, and a complete explanation of such amounts which are due, and each such certificate shall be conclusive, absent manifest error, that such amounts are due and owing. The Borrower shall have the right, at any time within 90 days of receipt of any such certificate, to prepay all the Loans (subject to any and all prepayment penalties and obligations to pay Funding Losses under the terms of this Agreement) without being obligated to pay any such additional costs set forth in such certificate, after which the Bank shall promptly terminate, discharge and release of record (at the Borrowers' expense) all of its Encumbrances affecting the Collateral and return all Collateral to the Borrower. Section 7.9. Indemnity. The Borrower agrees to indemnify the Bank and to hold the Bank harmless from and against any and all Funding Losses or any other loss, cost or expense that the Bank may sustain or incur as a consequence of (a) default by the Borrower in payment of the principal amount of or any interest on any Indebtedness as and when due and payable, including any such loss or expense arising from interest or fees payable by the Bank to lenders of funds obtained by it in order to maintain its LIBOR Rate in effect for the Loans, or (b) the making of any payment of Indebtedness on a day that is not the last day of the applicable Interest Period, including interest or fees payable by the Bank to lenders of funds obtained by it in order to maintain its LIBOR Rate in effect for the Loans. ARTICLE VIII SECURITY FOR THE INDEBTEDNESS Section 8.1. Security. The Indebtedness shall be secured by the following: (a) the Security Agreements; (b) the Mortgage; (c) Commercial Guaranty of the Borrower's indebtedness to the Bank by Aviation; and (d) Commercial Guaranty of the Borrower's indebtedness to the Bank by Omni Marine.
