In no event shall the total Net Collateral Value be 	 comprised of more than $2,000,000.00 in value from eligible 	 Foreign Accounts of the Grantors and eligible Accounts due to 	 American International Diving Limited. Lender, employing such 	 methods, tests and procedures as in its sole discretion it deems 	 appropriate or necessary, may at any time and from time to time 	 recalculate, audit and/or review such Accounts, the aging of such 	 Accounts and the Net Collateral Value as determined under any 	 Borrowing Base Certificate. If, in its sole judgment and 	 discretion, Lender determines that the Net Collateral Value 	 should be less than the Net Collateral Value shown on the most 	 recent Borrowing Base Certificate, then Lender may adjust such 	 Net Collateral Value accordingly. Within twelve (12) days after 	 the last day of each month, Borrower shall transmit to Lender, in 	 the manner provided herein for sending notices, the Borrowing 	 Base Certificate for the Accounts of the Grantors (which shall 	 list both separately and combined the Account data for each of 	 (a) American International Diving Limited and other Foreign 	 Accounts due to any Grantor, and (b) all Grantors (other than for 	 American International Diving Limited and for Foreign Accounts of 	 any Grantor) and, on a quarterly basis, a report of aging of such 	 Accounts both as of the end of the preceding fiscal quarter. The 	 aggregate amount of the Revolving Loans at any time, when added 	 to the aggregate unfunded amount of Credits at such time 	 outstanding, shall not at any time exceed the lesser of 	 (i) $15,000,000.00, or (ii) the Net Collateral Value as such 	 latter amount is determined by Borrower under the Borrowing Base 	 Certificate (or redetermined by Lender in its sole discretion). 	 If the aggregate amount of the Revolving Loans outstanding as of 	 the end of any month, when added to the aggregate unfunded amount 	 of Credits at such time outstanding, is less than $15,000,000.00 	 and less than the Net Collateral Value as of the end of such 	 month as indicated in the Borrowing Base Certificate for such 	 month or as adjusted by Lender under this Section for such month, 	 then Borrower shall be allowed to borrow additional Revolving 	 Loans up to an aggregate amount, which when added to the 	 Revolving Loans then outstanding plus the aggregate unfunded 	 amount of Credits at such time outstanding, does not exceed the 	 lesser of (i) $15,000,000.00 or (ii) such Net Collateral Value as 	 of the end of such month. If the aggregate amount of the 	 outstanding Revolving Loans as of the end of any month, when 	 added to the aggregate unfunded amount of Credits at such time 	 outstanding, exceeds the lesser of (i) $15,000,000.00 or (ii) the 	 Net Collateral Value as of the end of such month as indicated in 	 the Borrowing Base Certificate or as adjusted by Lender under 	 this Section, then Borrower shall pay the amount of such excess 	 within five (5) days following notice thereof from Lender. 				 ARTICLE III 				 THE TERM LOAN 	 a.The Term Loan. Subject to the terms, conditions and provisions 	 of this Agreement, Lender agrees to make a term loan (the "Term 	 Loan") to Borrower in the principal sum of $10,500,000.00. Based 	 upon the collateral previously provided for the Loans under the 	 existing Security Instruments, Lender has agreed, 	 contemporaneously herewith, to fund $6,283,329.06 of the Term 	 Loan to Borrower, the proceeds of which will be used to refinance 	 the amounts currently due under the Term Loans described in the 	 Prior Agreement. The remaining balance of the Term Loan shall be 	 funded an investment account (account no. AFL-772216) of Borrower 	 maintained with Marquis Investments, Inc. (the "Collateral 	 Account"). Prior to any advance under the Term Loan, Borrower 	 shall grant Lender a first priority security interest in the 	 Collateral Account. For so long as any Indebtedness remains 	 unpaid or Lender has any commitment to make Revolving Loans or to 	 issue Credits to Borrower hereunder, Borrower shall have no right 	 to withdraw or to otherwise request access to any funds in the 	 Collateral Account except to (i) request that such funds be 	 applied to the payment of the Loans, or (ii) subject to there not 	 being any Event of Default in existence hereunder at such time, 	 to request that Lender and Marquis Investments, Inc. make such 	 funds available to Borrower for it to apply (or for any of its 	 Subsidiaries to apply) towards the purchase price due on dive 	 support vessels to be acquired by Borrower or any of its 	 Subsidiaries. In no event shall funds held in the Collateral 	 Account be released to Borrower for the acquisition of vessels in 	 an amount in excess of 75% of the fair market value of any such 	 vessel(s) to be acquired using such proceeds of the Term Loan 	 then on deposit in the Collateral Account, with such fair market 	 value to be established by current surveys addressed to Lender by 	 a marine surveyor acceptable to Lender. Borrower shall 	 contemporaneously with the release of any such funds from the 	 Collateral Account grant (or cause its Subsidiary which shall 	 acquire title to any such vessel(s) to grant) Lender a first 	 priority preferred ship mortgage on the whole of such vessel(s) 	 as additional security for the Loans. 	 b.Evidenced by the Term Note. Borrower's indebtedness to Lender 	 pursuant to the Term Loan shall be evidenced by the Term Note. 	 c.Renewals and Extensions. In the event that Lender, in its sole 	 discretion, shall renew any portion(s) of any of the Term Loan 	 or, in its sole discretion, shall extend the maturity dates of 	 the Term Loan, then (i) any and all such renewal(s) or 	 extension(s) shall be in accordance with the terms, conditions, 	 representations, warranties and covenants of this Agreement 	 mutatis mutandis; (ii) all out-of-pocket expenses and costs, 	 including reasonable legal fees, incurred by Lender in connection 	 with any and all such renewal(s) or extension(s) and the 	 transactions contemplated thereby whether or not finally 	 consummated will be paid by Borrower; and (iii) such renewal(s), 	 if any, shall be evidenced by Lender's form of commercial 	 promissory note. 	 d.Repayment of the Term Loan. The principal amount of all 	 outstanding Term Loan shall be due and payable in accordance with 	 the terms of the Term Note. Interest on the Term Note shall 	 accrue at the fixed rate of 7.9% per annum from the date of the 	 Term Note until the Term Loan is paid in full, and shall be 	 payable in accordance with the terms of the Term Note. The Term 	 Note shall be due and payable in full on the earlier to occur of 	 (i) May 31, 2001, or (ii) the earlier date of the acceleration of 	 the Term Loans under the terms of Article XII, Section b hereof. 	 e.Prepayment. Borrower shall have the right to prepay the Term 	 Loans in whole or in part at any time, subject to its obligation 	 to pay a yield maintenance fee (the "Fee") which is intended to 	 compensate Lender for the difference between the fixed rate on 	 the prepaid loan and Lender's investment rate at the time of 	 prepayment. The Fee shall be the difference, if any, between (X) 	 the yield to maturity (expressed as a percentage) at the date of 	 the Term Note on U.S. Treasury Securities with a similar duration 	 as the Term Note, and (Y) the yield (expressed as a percentage) 	 at the date of prepayment on U.S. Treasury Securities with a 	 duration equal to the then remaining term of the Term Note, 	 multiplied by the principal amount to be prepaid and the then 	 remaining term to maturity in years. The total aggregate amount 	 of all such Fees for any and all prepayments shall not exceed 	 $100,000.00. Any prepayment of principal of the Term Loan shall 	 include all interest accrued to the date of prepayment, shall be 	 in addition to, and not in lieu of, all payments otherwise 	 required to be paid under the Loan Documents at the time of such 	 prepayment, and shall be applied in the inverse order of maturity 	 against the remaining scheduled installments of principal due on 	 the Term Loan. No amount prepaid with respect to the Term Loan 	 may be reborrowed. 	 (f)Collateral Maintenance. The amount of the Term Loan at any 	 time outstanding shall not exceed seventy-five percent (75%) of 	 the total market value of the vessels subject to the Ship 	 Mortgages, based upon the most current appraisals of such vessels 	 provided to Lender pursuant to Article X, Section r hereof. In 	 the event the outstanding amount of the Term Loan even exceeds 	 75% of the current appraised value of such vessels, Borrower 	 shall immediately prepay the Term Note by the amount of such 	 excess. 				 ARTICLE IV 		REVOLVING LOAN TRANCHES AND INTEREST PAYABLE THEREON 	 a.Tranches Available. Subject to the terms and conditions 	 hereof, the Revolving Loans may from time to time be (1) LIBO 	 Rate Tranches, (2) Base Rate Tranches, or (3) any combination 	 thereof subject to the limitation set forth in Section b(3) of 	 this Article, as determined by the Borrower and notified to the 	 Lender in accordance with Section d of this Article hereof. 	 b.Interest on Revolving Loans. (1) The unpaid principal of the 	 Revolving Note shall bear interest at one (or both) of the 	 following interest rates, at the Borrower's option: (i) the Base 	 Rate from time to time in effect, adjusted daily, or (ii) the 	 LIBO Rate plus two percent (2.0%). The Borrower shall select the 	 interest rate applicable to each Tranche, and the selected 	 interest rate shall continue as to said Tranche until changed in 	 accordance with the following. The Borrower shall notify the 	 Lender of the Borrower's desire to change the interest rate on 	 the Revolving Loans (or any portion thereof) not less than three 	 (3) Business Days prior to the date on which such change shall be 	 effective. The Borrower may change from a Base Rate Loan to a 	 LIBO Rate Loan at any time without payment of premium or penalty, 	 but the Borrower may change from a LIBO Rate Loan to a Base Rate 	 Loan only as of the last day of a LIBOR Interest Period without 	 payment of premium or penalty. In the absence of any specific 	 rate election by the Borrower, the Revolving Note shall bear 	 interest at the Base Rate. 	 (2)Borrower shall notify the Lender, such notice to be 	 irrevocable, at least three (3) Business Days prior to the last 	 day of a LIBOR Interest Period, of the duration of the next 	 succeeding LIBOR Interest Period with respect to such LIBO Rate 	 Tranche. If Borrower fails to provide such notice to the Lender 	 in a timely manner, the Revolving Note with respect to such LIBO 	 Rate Tranche shall bear interest at the Base Rate. 	 (3)Not more than two (2) different Tranches for the Revolving 	 Loans shall be permitted at any one time. 	 c.Payment of Interest. Interest on Base Rate Loans shall be 	 payable on the last Business Day of each month and interest on 	 LIBO Rate Loans shall be payable on each Interest Payment Date. 	 d.Conversion; Minimum Amount of Loans. (1) The Borrower may 	 elect from time to time to convert a LIBO Rate Tranche to a Base 	 Rate Tranche, or a Base Rate Tranche to a LIBO Rate Tranche, by 	 giving the Lender at least three Business Days' prior irrevocable 	 written notice of such election, provided that any such 	 conversion of a LIBO Rate Tranche shall only be made on the last 	 day of a LIBOR Interest Period with respect thereto. All or any 	 part of an outstanding LIBO Rate Tranche and a Base Rate Tranche 	 may be converted as provided herein, provided that (1) no Base 	 Rate Tranche may be converted into a LIBO Rate Tranche when any 	 Default or Event of Default has occurred and is continuing, (2) 	 partial conversions of a Base Rate Tranche to a LIBO Rate Tranche 	 shall be in an aggregate principal amount of $500,000 or a whole 	 multiple of $100,000 in excess thereof, (3) partial conversions 	 of a LIBO Rate Tranche to a Base Rate Tranche shall be in an 	 aggregate principal amount of $500,000 or a whole multiple of 	 $100,000 in excess thereof, (4) no Tranche may be converted into 	 a LIBO Rate Tranche after the date that is one month prior to the 	 Maturity Date, and (5) any such conversion may only be made if, 	 after giving effect thereto, Section d(3) of this Article IV 	 hereof shall not have been contravened. 	 (2)Any LIBO Rate Tranche may be continued as such upon the 	 expiration of a LIBOR Interest Period with respect thereto by the 	 Borrower giving the Lender at least three Business Days' prior 	 irrevocable written notice of such continuance; provided, that no 	 LIBO Rate Tranche may be continued as such (1) when any Default 	 or Event of Default has occurred and is continuing and the Lender 	 has determined that such a continuation is not appropriate or (2) 	 after the date that is one month prior to the Maturity Date, and 	 provided, further, that if the Borrower shall fail to give such 	 written notice or if such continuation is not permitted, then the 	 Borrower shall be deemed to have converted said LIBO Rate Tranche 	 to a Base Rate Tranche upon the expiration of the then current 	 LIBOR Interest Period. 	 (3)All borrowings, conversions and continuations of the Revolving 	 Loans hereunder and all selection of LIBOR Interest Periods 	 hereunder shall be in such amounts and be made pursuant to such 	 elections so that, after giving effect thereto the aggregate 	 principal amount of the Revolving Loans constituting a LIBO Rate 	 Tranche shall be equal to $500,000 or a whole multiple of 	 $100,000 in excess thereof. 				 ARTICLE V 			 CERTAIN GENERAL PROVISIONS 	 a.Payments to Lender. All payments of principal, interest, 	 commitment fees and any other amounts due hereunder or under any 	 of the other Loan Documents shall be made to the Lender at the 	 Lender's office at 210 Baronne Street, New Orleans, Louisiana 	 70112, or at such other location that the Lender may from time to 	 time designate in writing to Borrower, in each case in 	 immediately available funds. 	 b.No Offset, etc.. All payments by Borrower hereunder and under 	 any of the other Loan 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 Borrower is compelled by law to make such 	 deduction or withholding. If any such obligation is imposed upon 	 Borrower with respect to any amount payable by it hereunder or 	 under any of the other Loan Documents, Borrower will pay to the 	 Lender, on the date on which such amount is due and payable 	 hereunder or under such other Loan Document, such additional 	 amount in Dollars as shall be necessary to enable the Lender to 	 receive the same net amount which Lender would have received on 	 such due date had no such obligation been imposed upon Borrower. 	 Borrower will deliver promptly to the Lender certificates or 	 other valid vouchers for all taxes or other charges deducted from 	 or paid with respect to payments made by Borrower hereunder or 	 under such other Loan Documents. 	 c.Computations. All computations of interest on the Loans and of 	 commitment or other fees shall be based on a 360-day year and 	 paid for the actual number of days elapsed. Except as otherwise 	 provided in the definition of the term "LIBOR Interest Period", 	 whenever a payment hereunder or under any of the other Loan 	 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 Lender's books and records from time to time shall be prima 	 facie evidence of the amounts so outstanding. 	 d.Inability to Determine LIBO Rate. In the event, prior to the 	 commencement of any LIBOR Interest Period, the Lender shall 	 determine or be notified that adequate and reasonable methods do 	 not exist for ascertaining the LIBO Rate that would otherwise 	 determine the rate of interest to be applicable to the Revolving 	 Loans during any LIBOR Interest Period, the Lender shall 	 forthwith give notice of such determination (which shall be 	 conclusive and binding on Borrower) to Borrower. In such event 	 the Revolving Loan will automatically, on the last day of the 	 then current LIBOR Interest Period thereof, become a Base Rate 	 Loan until the Lender determines that the circumstances giving 	 rise to such suspension no longer exist, whereupon the Lender 	 shall so notify Borrower. 	 e.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 Lender to make available, or maintain in effect, the LIBO 	 Rate, the Lender shall forthwith give notice of such 	 circumstances to Borrower and thereupon the Revolving Loans shall 	 be converted automatically to a Base Rate Loan on the last day of 	 the then current LIBOR Interest Period or within such earlier 	 period as may be required by law. Borrower hereby agrees 	 promptly to pay the Lender, upon demand by the bank, any 	 additional amounts necessary to compensate the Lender for any 	 costs incurred by the Lender in making any conversion in 	 accordance with this paragraph, including any interest or fees 	 payable by the Lender to lenders of funds obtained by it in order 	 to make available, or maintain in effect, the LIBO Rate for the 	 Revolving Loans. 	 f.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 Lender by any central bank or other fiscal, monetary or 	 other authority (whether or not having the force of law), shall: 	 (1)subject the Lender to any tax, levy, impost, duty, charge, 	 fee, deduction or withholding of any nature with respect to this 	 Loan Agreement, the other Loan Documents or the Indebtedness 	 (other than taxes based upon or measured by the revenue, income 	 or profits of the Lender), or 	 (2)materially change the basis of taxation (except for changes in 	 taxes on revenue, income or pots) of payments to the Lender of 	 the principal of or the interest on the Indebtedness of any other 	 amounts payable to the Lender under this Agreement or the other 	 Loan 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 Lender, or 	 (4)impose on the Lender any other conditions or requirements with 	 respect to this Loan Agreement, the other Loan 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 Lender of issuing Credits or 	 making, funding, issuing, renewing, extending or maintaining the 	 Indebtedness, or 	 (ii)to reduce the amount of principal, interest or other amount 	 payable to the Lender hereunder on account of such the 	 Indebtedness, or 	 (iii)to require the Lender 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 Lender from Borrower hereunder, then, and in each 	 such case, Borrower will, upon demand made by the Lender at any 	 time and from time to time and as often as the occasion therefor 	 may arise, pay to the Lender such additional amounts as will be 	 sufficient to compensate the Lender for such additional cost, 	 reduction, payment or foregoing interest or others sum. 	 g.Capital Adequacy. If after the date hereof the Lender 	 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 Lender or any corporation controlling the 	 Lender 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 Lender's Loans to a level below that 	 which the Lender could have achieved but for such adoption, 	 change or compliance (taking into consideration the Lender's then 	 existing policies with respect to capital adequacy and assuming 	 full utilization of such entity's capital) by any amount deemed 	 by the Lender to be material, then the Lender may notify Borrower 	 of such fact. Borrower agrees to pay the Lender for the amount 	 of such reduction in the return on capital as and when such 	 reduction is determined upon presentation by the Lender of a 	 certification in accordance with paragraph. The Lender shall 	 allocate such cost increases among its customers in good faith 	 and on an equitable basis. 	 h.Certificate. A certificate setting forth any additional 	 amounts payable pursuant to Article V, Sections f and g, and a 	 complete explanation of such amounts which are due, submitted by 	 the Lender to Borrower, shall be conclusive, absent manifest 	 error, that such amounts are due and owing. 	 i.Indemnity. Borrower agrees to indemnify the Lender and to hold 	 the Lender harmless from and against any loss, cost or expense 	 that the Lender may sustain or incur as a consequence of (a) 	 default by 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 Lender to lenders of funds obtained by it in order 	 to maintain its LIBO Rate in effect for the Revolving Loans, or 	 (b) the making of any payment of Indebtedness on a day that is 	 not the last day of the applicable LIBOR Interest Period, 	 including interest or fees payable by the Lender to Lenders of 	 funds obtained by it in order to maintain its LIBO Rate in effect 	 for the Revolving Loans. 				 ARTICLE VI 				 CREDITS 	 a.The Credits. Upon the written application of Borrower, in 	 substantially the form of Exhibit "B" (the "Credit Application"), 	 executed by Borrower (or by any one of the persons designated by 	 Borrower in writing to Lender in accordance with the terms 	 hereof), Lender agrees, upon satisfaction of the terms and 	 conditions of this Agreement and upon approval by Lender (in its 	 sole discretion) of the terms of the requested Credit to be 	 issued pursuant to the Credit Application, that it will issue an 	 irrevocable standby letter of credit for the account of Borrower 	 (a "Credit") substantially in accordance with the Credit 	 Application. Each Credit issued hereunder shall expire on a 	 business day not later than the Maturity Date. In no event shall 	 a Credit be issued by Lender if the sum of the face amount 	 thereof when added to the aggregate unfunded amount of Credits 	 then outstanding plus the aggregate principal amount of the 	 Revolving Loans at such time outstanding exceeds the lesser of 	 (i) $15,000,000.00, or (ii) the Net Collateral Value in effect at 	 such time. 	 b.Issuance of Credits. Each Credit shall be issued not later 	 than three (3) Business Days after receipt by lender of the 	 Credit Application related thereto. No later than 12:00 noon 	 (New Orleans time) on the third Business Day following receipt of 	 the Credit Application and upon fulfillment of the applicable 	 conditions set forth in this Agreement, Lender shall issue its 	 Credit. Lender 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 Lender, and any such termination of authority shall 	 be effective only prospectively. 	 c.Credit Commission. Borrower agrees to pay to Lender the 	 standard fees charged and established by Lender from time to time 	 for the issuance of letters of credit (the "Credit Commission") 	 with respect to each Credit created by Lender hereunder. Payment 	 of such Credit Commission with respect to each Credit created by 	 Lender shall be paid in advance on the date of issuance of the 	 Credit. 	 d.Credit Obligations. Borrower agrees unconditionally to pay 	 Lender on demand in United States currency at Lender'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 which complies with any 	 such Credit's terms and conditions for payment, (b) any and all 	 costs, charges, fees and/or expenses incurred or paid by Lender 	 in connection with any Credit, 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, Borrower agrees to make the aforementioned payment to 	 Lender in United States currency at Lender's selling rate for 	 cable transfers to the place of payment of such Draft on the date 	 of such payment. Such obligation of Borrower shall be deemed a 	 Credit Obligation hereunder. 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. Borrower further authorizes Lender, at 	 its option, to compensate itself by applying any part or all of 	 the balance of any deposit account or certificate of deposit 	 which Borrower may maintain with Lender, 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 Lender's hands, or in 	 transit to or from Lender, and belonging to Borrower, to the 	 payment, in whole or in part, of the amount of any draft and all 	 interest, costs and attorney's fees which Borrower may owe Lender 	 pursuant to this Agreement. In the event a Credit Obligation is 	 not paid when demanded by Lender, Borrower agrees to pay to 	 Lender on demand a sum equal to the amount of the Credit 	 Obligation, plus interest thereon from the date the Credit 	 Obligation is demanded by Lender until paid at the Base Rate. A 	 payment shall not be deemed made until funds therefor have been 	 actually collected and made available to Lender. Upon the 	 occurrence of an Event of Default hereunder, Borrower agrees to 	 pay to Lender on demand a sum equal to the aggregate unfunded 	 amounts of all Credits outstanding, together with interest 	 thereon at the interest rate then being charged for Revolving 	 Loans (such obligation of Borrower shall be deemed a Credit 	 Obligation as such term is used herein). Upon the occurrence of 	 such Event of Default, Lender may exercise its right of offset 	 and compensation set forth above in this paragraph. Any amount 	 which Lender offsets or which Borrower may pay to Lender in 	 excess of drafts actually drawn on any outstanding Credits shall 	 be held by Lender in pledge to secure the payment of future 	 drafts until Lender's obligation to make Loans has been 	 terminated, all Indebtedness has been paid in full, and no 	 further Credits are outstanding. 	 e.Revolving Credit Loans. In the event that Credit Obligations 	 owed Lender 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 Article 	 II, Section h(1) hereof, such Credit Obligations shall be 	 immediately paid by Borrower pursuant to a Revolving Loan in the 	 amount of such Credit Obligations. Such Credit Obligations shall 	 be immediately converted to a Revolving Loan by Lender and shall 	 be evidenced by the Note. If at any time any Event of Default 	 occurs and any portion of any Credits remains unfunded, Borrower 	 shall pay to Lender in cash for application to future drawings 	 under the outstanding Credits, an amount equal to the aggregate 	 unfunded portion of the outstanding Credits. If Borrower does 	 not pay such amount on demand, notwithstanding the limitation 	 contained in Article II, Section h(1), such amount shall be 	 immediately paid by Borrower by a Revolving Loan to Borrower from 	 Lender. Such amount shall be immediately converted to a 	 Revolving Loan by Lender and shall be evidenced by the Revolving 	 Note. The amount of such Revolving Loan shall be held by Lender 	 in pledge securing Borrower's obligations under this Agreement, 	 with Borrower hereby granting Lender a continuing security 	 interest in such funds as security for the Indebtedness until 	 Lender's obligation to make Revolving Loans has terminated, all 	 Indebtedness has been paid in full, and no further Credits are 	 outstanding. 				 ARTICLE VII 				SECURITY INSTRUMENTS 	 As security for the Indebtedness, Borrower and the other Grantors 	 have heretofore or contemporaneously herewith furnished to Lender 	 the Security Instruments. Borrower hereby confirms and 	 acknowledges that such Security Instruments to which it is a 	 party (including those previously granted) shall secure the 	 Indebtedness as herein defined, and Borrower agrees that it shall 	 cause the other Grantors to provide the Lender with similar 	 confirmations and acknowledgments of the Security Instruments 	 previously granted by them. In addition, Borrower shall execute 	 and deliver (and cause the other Grantors to execute and deliver) 	 to Lender all amendments to the Security Instruments as shall be 	 reasonably requested by Lender to adequately secure payment of 	 the Indebtedness as herein described. 				 ARTICLE VIII 			 REPRESENTATIONS AND WARRANTIES 	 In order to induce Lender to make the Loans, Borrower hereby 	 represents, warrants and covenants to Lender as follows: 	 a.Status of Borrower and Grantors.

Lender may, from time to time, at its sole discretion, and with 	 or without valuable consideration or notice to any party, allow 	 substitution or withdrawal of any and all security for the 	 Indebtedness. Lender may, without in any manner impairing or 	 diminishing the obligations of any other party, elect to pursue 	 any available remedy against any party hereto or against any 	 security for the Indebtedness, whether or not the exercise by 	 Lender of any such remedy shall result in the loss to any party 	 of any right to subrogation or right to proceed against any other 	 party for reimbursement. 	 n.Originals. This Agreement shall be executed in multiple 	 originals, each of which shall be deemed an original. In making 	 proof of this agreement for any reason, it shall not be necessary 	 to produce more than one original. 	 o.Counterparts.

You are hereby authorized, at any time and from time to 	 time, at your option, to compensate yourself by applying any part or 	 all of the balance of each and every deposit account or Certificate of 	 Deposit of any of us maintained with you (with the exception of IRA, 	 pension and other types of tax-deferred accounts), whether or not the 	 deposit account or Certificate of Deposit is mature and/or any or all 	 monies now or hereafter in the hands of you, or in transit to or from 	 you, and belonging to any of us, to the payment, in whole or in part, 	 of the Credit or any other Indebtedness, whether or not the Credit or 	 other Indebtedness is due or has been demanded. 2. If any draft is drawn on you pursuant to the Credit, we authorize you, 	 at your option, to compensate yourself by applying any part or all of 	 the balance of every deposit account or Certificate of Deposit which we 	 may maintain with you at any time, whether or not the deposit is 	 mature, and/or any or all monies or other property or interest of any 	 kind now or hereafter in your hands, or in transit to or from you, and 	 belonging to us, to the payment, in whole or in part, of the Principal 	 and any interest, costs and attorney's fees which we may owe to you 	 pursuant to this Agreement. 3. In the event any draft is drawn on you pursuant to the Credit and you 	 do not elect to exercise your right of offset and compensation set 	 forth in paragraph 2 of this Agreement, we agree to pay to you on 	 demand at the Main Office a sum which will equal the amount of the 	 draft, plus interest thereon from the date the draft is drawn on you 	 pursuant to the Credit until paid at the rate per annum of _________. 	 Interest will be calculated on the number of actual days elapsed based 	 on a year of 360 days. All payments may be applied first to interest, 	 then to insurance premiums and other charges (if applicable), then to 	 Principal. A payment shall not be deemed made until the funds 	 therefore have been actually collected and made available to you at the 	 Main Office. 4. In the event any draft is drawn on you pursuant to the Credit in an 	 amount less than the full amount of the Principal, you may still 	 exercise your rights pursuant to the provisions of paragraph 2 and 3 	 for the full amount of the Principal. Any amount which you offset 	 pursuant to the provisions of paragraph 2 or which we must pay to you 	 pursuant to the provisions of paragraph 3 which are in excess of drafts 	 actually drawn on you pursuant to the Credit shall be held by you in 	 pledge to secure the payment of future drafts until 30 days after the 	 Expiration Date or after any extension of the Expiration Date whichever 	 is later. Any amounts so paid by us to you which have not been drawn 	 by 30 days after the Expiration Date or after any extension of the 	 Expiration Date whichever is later, shall be repaid to us without 	 interest. 5. We also agree to pay you, on demand, a commitment fee for the Credit, 	 which fee shall be calculated as follows: ____________. We understand 	 that we are not entitled to a refund of any portion of the commitment 	 fee under any circumstances, including, but not limited to, your 	 unilateral reduction, early termination, or other modification of the 	 Credit. We additionally agree to pay you all charges and expenses 	 incurred in connection with the Credit, including, but not limited to 	 collection costs, court costs and attorney's fees. 6. We agree that, regardless of any extension of the Expiration Date, any 	 increase in the amount of the Credit, or any other modification of the 	 terms of the Credit, this Agreement shall be binding upon us. No such 	 modification of the Credit or this Agreement will be effective unless 	 agreed to in writing by you. 7. Each of the following shall constitute an Event of Default under this 	 Agreement: should we make any misrepresentation to you in connection 	 with the obtaining of the Credit; should we be in default with respect 	 to any payment of Principal, interest, commitment fees, costs or 	 attorney's fees under this Agreement; should we fail to pay all or any 	 part of the Principal in accordance with the provisions set forth 	 herein; should there be a default in any mortgage or pledge securing 	 our payment of all or any part of the Principal, interest and other 	 charges; should we be in default with respect to any other obligation 	 contained herein, or with respect to any obligation owed by us to you 	 or others for the repayment of borrowed monies; should we file a 	 petition under any chapter of the Federal Bankruptcy Act or any similar 	 state or federal law, whether now or hereafter existing; should any 	 bankruptcy proceeding be commenced against us and should we fail to 	 file an answer controverting and opposing the petition, or fail to 	 obtain a dismissal of such action within 45 days of its commencement; 	 should we be the subject of an order for relief against us in any such 	 bankruptcy proceeding or have a custodian (as defined in the Federal 	 Bankruptcy Act) or a state court keeper or receiver or trustee 	 appointed for us or have any court take jurisdiction of any part of our 	 property in any involuntary proceedings for the purpose of 	 reorganization, arrangement, dissolution or liquidation and the court's 	 jurisdiction is not terminated or the trustee, keeper or receiver is 	 not discharged within 45 days after the commencement of such 	 proceedings; should we apply for any such relief under state law; 	 should we make a general assignment for the benefit of creditors or 	 have appointed a committee of creditors; should there be called a 	 meeting of our creditors; should we admit our inability to pay our 	debts as they become due; should we suspend the transaction of our usual 	 business; or, should you in any way deem yourself insecure at any time. 	 Upon the occurrence of an Event of Default, all outstanding Principal 	 and any and all other indebtedness which we may owe to you shall, at 	 your option, become immediately due and payable. If at the time any 	 Event of Default occurs, any portion of the Credit remains undisbursed, 	 we shall pay to you in cash, within 24 hours of your demand therefor, 	 for application to drawings under the Credit, an amount equal to such 	 undisbursed portion of the Credit. If we do not pay such amount on 	 demand, you shall have the right, without prejudice to your other 	 rights, to collect such amount pursuant to paragraphs 2 and 3 above, 	 and to hold that sum in pledge as provided in paragraph 4 above. Any 	 amounts which we have paid to you on such demand and which have not 	 been drawn by 30 days after the Expiration Date, or after any extension 	 of the Expiration Date, whichever is later, shall be repaid to us 	 without interest. 8. We agree that you may at any time deliver the Credit through any 	 bank(s) ("Correspondents") you in your sole discretion may choose. We 	 hold you harmless for any actions or claims arising out of the handling 	 of such delivery by the Correspondents making the delivery. We further 	 agree that neither you nor any Correspondents shall ever in any way be 	 responsible for performance by any beneficiary of its obligations to us 	 nor for the form, validity, sufficiency, correctness, truthfulness or 	 genuineness of any documents delivered in connection with the 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 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, telegraph or otherwise; or, for any error, 	 neglect or default of any Correspondents. We further agree that, if any 	 of the above events should occur, such event will not affect, impair or 	 prevent our liability or your rights or powers hereunder. We agree 	 that any action taken by you or by any Correspondent in connection with 	 the Credit, including but not limited to relative drafts, documents, or 	 property, as well as any inaction or omission, shall not result in 	 liability to you or any Correspondent. 9. Without limiting the foregoing, and in addition to the provisions of 	 paragraph 8 hereof, you are 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 duly on 	 your part to inquire into, the existence of any, disputes or 	 controversies between any of the undersigned, 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 of the documents presented under the Credit are true 	 or correct. We fully understand and agree that your sole obligation to 	 us shall be limited to honoring requests for payment made under and in 	 compliance with the terms of the Credit are true or correct. We fully 	 understand and agree that your sole obligation to us shall be limited 	 to honoring requests for payment made under and in compliance with the 	 terms of the Credit and this Agreement and your obligation remains so 	 limited even if you may have assisted us in the preparation of the 	 wording of the Credit or any documents required to be presented 	 thereunder or if you may otherwise be aware of the underlying 	 transaction giving rise to the Credit and this Agreement. 10. We agree, at any time and from time to time whether or not any drafts 	 have been drawn pursuant to this Credit and whether or not there has 	 occurred any Event of Default under this Agreement or any other 	 agreement we may have with you, within 24 hours of demand by you, to 	 deliver, convey, transfer, pledge and/or assign to you, as security for 	 payment of Principal, interest and other charges and performance of 	 this Agreement, security or additional security of a value and 	 character satisfactory to you and to make such payments to you as you 	 may require pursuant to the terms of this Agreement. 11. We agree to maintain insurance on all property mortgaged or pledged to 	 secure this Agreement, insuring you against the loss of such property 	 by flood, fire, theft or other peril, for the term of the Credit and 	 all extensions or renewals of the Credit. If we should fail to insure 	 the mortgaged or pledged property and deliver a copy of the insurance 	 policy to you within 30 days of the execution of this Agreement, or if 	 we fail to obtain a renewal policy immediately, or if we obtain such 	 insurance but for any reason it is cancelled, in whole or in part, at 	 any time before the Expiration Date of the Credit including extensions 	 or renewals thereof, and we fail to obtain a renewal policy 	 immediately, or if we fail to pay taxes or assessments on the mortgaged 	 or pledged property or permit any liens to be placed against the 	 property, you, in addition to any other rights you may have under this 	 Agreement, shall have the right to obtain and pay for such policy, such 	 taxes or assessments, and the amount necessary to discharge such liens, 	 up to the amount of One Million ($1,000,000.00) Dollars, and all such 	 amounts shall be secured by this Agreement and by all collateral now or 	 hereafter given to secure our obligations to you. If, in your opinion, 	 it is necessary at any time, whether or not an Event of Default occurs, 	 to perform repair work on the mortgaged or pledged property in order to 	 put it into suitable condition for sale, you are authorized to make 	 such repairs and all amounts spent for such purposes up to the amount 	 of Two Hundred Thousand ($200,000.00) Dollars shall be secured by this 	 Agreement and by all accounts or collateral now or hereafter in your 	 possession and/or given to secure our obligations to you. 	 The immediately preceding paragraph does not oblige you to procure 	 insurance, pay taxes or assessments, discharge liens, or repair 	 property, but provides an option for you to do so. You may demand 	 immediate reimbursement from us of any such amounts spent by you. Our 	 failure to repay such amounts within 24 hours of such demand shall, at 	 your option, constitute an Event of Default. 12. We bind ourselves to pay the fees of any attorney at law whom you may 	 employ to recover the Principal, the commitment fee, or any interest or 	 other cost owing to you by us pursuant to this Agreement, or any part 	 hereof, or to protect any security given hereunder or your interest 	 herein, or to compromise or take any other action with regard hereto, 	 which fees are hereby fixed at 25% of the amount then owing or sought 	 to be collected, protected, or preserved. 13. We waive presentment for payment, notice of nonpayment, demand, 	 protest, notice of protest, all pleas of division and discussion and 	 agree that the time of payment of the Principal, interest and other 	 charges may be extended, from time to time one or more times, without 	 notice of such extensions and without further consent. Without notice 	 to us, or without our further consent, you may substitute, release, 	 discharge or otherwise alter any one or more of our obligations without 	 affecting in any way any other of our obligations. No waiver of any 	 right by you shall be effective except as specifically provided in 	 writing. No delay by you in the exercise of any right shall affect 	 such right, nor preclude future exercise of such or similar rights. 14. When you are required to make demand upon us pursuant to this 	 Agreement, demand shall be deemed to have been made on the date and 	 hour when you have either telephoned us or have sent written notice of 	 demand to the most recent address which we have given you in writing, 	 by telegraph, telex, cable or registered mail. 15. We agree that even if the Letter of Credit is issued in a foreign 	 currency, the principal amount of each drawing, for the purposes of 	 determining the Principal outstanding, will be the U.S. Dollar 	 equivalent of the foreign currency amount converted at the rate of 	 exchange which is determined by you at the rate you in your sole 	 discretion may set on the date of any drawing. Further, we indemnify 	 you and your Correspondents against all obligations, liabilities and 	 responsibilities which are imposed by or result from foreign laws, 	 customs and usages. 16. We understand that if the Letter of Credit is designated as 	 "transferable," any transfer will only be effective after you have 	 received and acknowledged written notice of the transfer. 17. If this Agreement is signed by one party, the terms "we," "our," "us," 	 shall be read throughout as "I," "my," "me," as the case may be. If 	 this Agreement is signed by two or more parties, it shall be the joint, 	 several and solidary obligation of such parties, and the terms "we," 	 "our," and "us," shall be read throughout as "our, or any of our," and 	 "us, or any of us." The terms "we," "our," and "us," as used in this 	 Agreement mean each maker, endorser, guarantor, or other surety of the 	 Principal, interest and other charges and any and all other 	 indebtedness owing by us to you, including any person or entity 	 pledging or mortgaging property to secure the Principal and any and all 	 other indebtedness arising pursuant to this Agreement, as well as their 	 heirs, successors or assigns. The terms "you" and "your," shall be 	 read throughout to refer to Bank, its successors, transferees and 	 assigns. 18. In the event that any provision of this Agreement is invalidated by a 	 change in existing law or regulations or by a decision of any court 	 having jurisdiction over this Agreement or the parties hereto, such 	 provision will be considered as having been severed from this 	 Agreement, and the remaining provisions of this Agreement will continue 	 in full force and effect. 19. This Agreement shall be deemed to be made under and shall in all 	 respects be governed by the laws of the State of Louisiana. The Credit 	 will be subject to the Uniform Customs and Practice for Documentary 	 Credits (1993 Revision), International Chamber of Commerce Publication 	 No. 500 or by subsequent Uniform Customs and Practice fixed by 	 subsequent Congresses of the International Chamber of Commerce.
