If any amount payable to the Bank hereunder by the Borrowers shall not be paid when due or the payment is made in funds which are not immediately available or any other Event of Default has occurred and remains in existence, the Borrowers agree to pay to the Bank interest, to the extent permitted by applicable law, on the entire principal amount of the Borrowers' Obligations at a rate which is at all times equal to three percent (3%) PER ANNUM in excess of the then current rate of interest on the Loan as described in the Promissory Note until such amount shall be paid in full or until funds are immediately available or other Event of Default is cured, as the case may be.

(b) Export Inventory will be valued at 75% of the lesser of its wholesale cost or market value, from time to time, provided that each item of Export Inventory, including work-in-process, satisfies the following eligibility requirements and provided further that at no time shall the Collateral Value of Export Inventory support more than 60% of the outstanding Loan Obligations plus the aggregate stated amount of Commercial Letters of Credit: (i) the Export Inventory is held by ASI for export sale and is located within the United States; and (ii) the Export Inventory has been purchased, assembled or manufactured by ASI in the ordinary course of business, but not for speculative sale, and does not constitute demonstration Export Inventory or proprietary software (unless incorporated into or made part of a system), and is actually owned by, and in the possession of, ASI and not merely in the possession of ASI on a consignment or similar basis, and the Export Inventory has not been sold or disposed of by ASI and is not subject to the lien or security interest of any other Person except for Permitted Liens; and (iii) the Export Inventory is not considered by ASI or other corporations which engage in substantially the same business as ASI to be damaged, defective, unmerchantable, slow moving or obsolete, and has not been returned by any other purchaser and is not defective, recalled or unfit for further 28 processing and has not been previously sold or exported from the United States; and (iv) the Export Inventory is located at an address which has been disclosed in Section 6.14 of this Agreement or by written supplement thereto delivered to the Bank and is included in the universe of Collateral with respect to which the Bank has filed a financing statement among all records required by the Uniform Commercial Code of the jurisdiction in which ASI maintains its principal place of business in order to properly perfect the Bank's security interest, and the Export Inventory is not evidenced by Chattel Paper (within the meaning of the Uniform Commercial Code) or any other documents of title; and (v) the Export Inventory is not in the possession of a processor or bailee, or located on a premises leased or subleased to ASI or located on a premises subject to a mortgage in favor of a Person other than the Bank, unless the processor, bailee, lessor, sublessor or mortgagee (as the case may be) has executed and delivered all documentation reasonably required by the Bank to evidence the subordination or extinguishment of rights to the Collateral and to confirm the Bank's right to gain access to such premises to exercise any and all rights against the Collateral; and (vi) the Export Inventory does not constitute and is not to be incorporated into any items which are destined for shipment to any country which has been identified on EXIMBANK's Country Limitation Schedule as either (A) a country in which EXIMBANK is prohibited from doing business in the public or private sector (as appropriate), or (B) a country which is not available in the public or private sector (as appropriate) for EXIMBANK-guaranteed financing due to commercial reasons, unless the purchase price of such item of Export Inventory to be sold within any such country is secured by an irrevocable letter of credit issued or confirmed by a financial institution acceptable to EXIMBANK; and (vii) the Export Inventory does not constitute defense articles or defense services and is not destined to be purchased for military defense purposes; and (viii) any Export Inventory which is listed on the United Munitions List (Art 121 of Title 22 of the Code of Federal Regulations), unless ASI shall have provided written notice to the Bank describing such items of Export Inventory and the corresponding invoice amount for each and EXIMBANK shall have approved such Export Inventory for financing under the Commitment; and 29 (ix) the Export Inventory contains at least 50% U.S. content, which is defined to include all labor, materials and services which are of United States origin or manufacture and which are incorporated into an item within the United States; and (x) the Export Inventory was not produced in violation of the Fair Labor Standards Act and it not subject to the "hot goods" provisions contained in 29 UJC ss.215 or any successor statute; AND (xi) the sale of the Export Inventory will not result in an ineligible Receivable. Upon the sale, shipment or other disposition of any item of Export Inventory, such item of Export Inventory shall cease to have Collateral Value as Export Inventory; however, the resulting Export Receivable shall have Collateral Value provided that it otherwise satisfies all of the eligibility criteria for Export Receivables described above. No Collateral other than Export Receivables and Export Inventory which satisfy the eligibility requirements contained in paragraphs (a) and (b) above shall have a value for purposes of determining the amount of the Available Commitment from time to time. Any Export Receivable or Export Inventory which subsequently fails to satisfy any of the eligibility requirements set forth in this Section shall immediately cease to have any value for purposes of determining the amount of the Available Commitment from time to time. For purposes of facilitating compliance by the Borrowers with the foregoing eligibility requirements, a copy of EXIMBANK's current Country Limitation Schedule is attached as Schedule I to this Agreement. This Schedule is revised, amended and updated periodically, and the Bank will endeavor to provide the Borrowers with copies of any supplements and modifications to the Country Limitation Schedule which are provided to it by EXIMBANK. 5.4 LOCATION OF COLLATERAL: PRINCIPAL PLACE OF BORROWERS' BUSINESSES: The Borrowers agree to keep the Bank informed as to the location of the Collateral and the address of each Borrower's principal place of business, give the Bank prior notice of any contemplated changes of location or the address of either Borrower's principal place of business, and not change the location of any of the Collateral or the address of either Borrower's principal place of business, without the prior written consent of the Bank. Notwithstanding the foregoing, with notice to, but without the need for obtaining the consent of the Bank, the Borrowers may move Collateral among locations where the Bank has filed Financing Statements to properly perfect its lien in the Collateral. 5.5 LOSS OF COLLATERAL. The Bank shall not be liable for any loss of any Collateral in its possession unless such loss is directly caused by the gross negligence or willful misconduct of the Bank. In no event any shall such loss diminish the debt due. 30 5.6 FILING OF FINANCING STATEMENTS: PERFECTION OF SECURITY INTEREST IN COLLATERAL. (a) The security interest created by this Agreement shall be perfected by the filing of financing statements which fully comply with Article 9 of the Uniform Commercial Code, as adopted by each of the states in which the Collateral may be located, in such offices as may be required by the Bank.

(b) To the extent deemed necessary or appropriate by the Bank, the security interest created by this Agreement in any items of Collateral, for which the UCC requires possession in order to perfect the Bank's lien in such item of Collateral, shall be perfected by the delivery to the Bank or, with the Bank's consent, to agents, branches, affiliates, correspondents or others acting on behalf of the Bank, of all such Collateral as security for the Borrowers' Obligations. (c) The security interest created by this Agreement in any Receivable which is owed to either Borrower by any state or political subdivision thereof or by the United States or any department, agency or instrumentality thereof, shall be further perfected by such Borrower's execution and delivery to the Bank of any instruments, the giving of any notices, and the taking of any additional steps which may be required by the Federal Assignment of Claims Act, the Federal Assignment of Contracts Act or any equivalent provision of state or local law in order to ensure the effectiveness of the assignment of such Receivable against the account debtor. (d) The security interest created by this Agreement in any unsecured Export Receivable shall be further perfected by the execution and delivery to the Bank of any instruments and the giving of any notices and the taking of any additional steps which may be required under foreign law in order to ensure the effectiveness of the assignment of such Export Receivable against the Account Debtor. 5.7 ASSIGNMENT OF LETTER OF CREDIT PROCEEDS.

(b) The Borrowers will take all necessary and advisable steps to ensure that each letter of credit described in paragraph (a) above will either (i) be delivered to the paying or confirming bank and that said paying or confirming bank shall be authorized to retain the letter of credit on behalf of the Bank as the assignee of the proceeds thereof, or (ii) be retained by such Borrower, if no paying or confirming bank has been designated. (c) In order to perfect the Bank's assignment of the proceeds of the letters of credit issued for such Borrower's benefit, each Borrower agrees to act as the 32 agent of the Bank for the purposes of (i) accepting delivery of all such letters of credit, and (ii) holding such letters of credit for the benefit of the Bank until such time as the letters of credit are delivered to the paying or confirming bank in accordance with paragraph (b) above. (d) In the event that either Borrower is unable to obtain the assignment of the letter of credit in accordance with paragraph (a) above, such Borrower shall be required to arrange in writing (with a copy to the Bank) with the account party under any such letter of credit that the issuer of said letter of credit include therein a provision to the effect that payment under said letter of credit shall be negotiated only at the Bank's counters or, alternatively, that payment shall be made only to the Borrowers' Account. 5.8 ASSIGNMENT OF CONTRACT/PURCHASE ORDER PROCEEDS. The Borrowers shall assign to the Bank, immediately after the execution of a contract of sale with an importer or receipt of a purchase order from an importer, all amounts to be paid to such Borrower under that contract or purchase order.

If the Borrowers shall fail to pay any of the Borrowers' Obligations or the Borrowers shall otherwise fail to perform, observe or comply with any of the conditions, covenants, terms, stipulations or agreements contained in this Agreement or any of the other Financing Documents and the same results in an Event of Default hereunder, the Bank, without notice to or demand upon the Borrowers, and without waiving or releasing any of the Borrowers' Obligations or any Event of Default, and in addition to any rights or remedies available to it under any of the other Financing Documents, may (but shall be under no obligation to) at any time thereafter make such payment or perform such act for the account and at the expense of the Borrowers, and may, to the extent permitted by law, enter upon the premises of the Borrowers for that purpose and take all such action thereon as the Bank may consider necessary or appropriate for such purpose. All sums so paid or advanced by the Bank and all costs and expenses (including, without limitation, reasonable attorneys' fees and expenses) incurred in connection therewith (the "Expense Payments") together with interest thereon from the date of payment of the advance or the date on which the expense was incurred until paid in full at the rate of three percent (3%) per annum in excess of the Prime Rate shall be paid by the Borrowers to the Bank on demand and shall constitute and become a part of the Borrowers' Obligations. (h) NO CONDITIONS PRECEDENT TO EXERCISE OF REMEDIES. The Borrowers shall not be relieved of any obligation by reason of the failure of the Bank to comply with any request of the Borrowers or of any other person, to sell any portion of the Collateral, or otherwise to enforce any provision of the Financing Documents, or by reason of the release, regardless of consideration, of all or any part of the Collateral, or other security for the Borrowers' Obligations, or by reason of any agreement or stipulation between any subsequent owner of the Collateral or other security for the 55 Borrowers' Obligations, or the Bank extending the time of payment or modifying the terms of the Financing Documents without first having obtained the consent of the Borrowers; and in the latter event, the Borrowers shall continue to be liable to make payments according to the terms of any such extension or modification agreement, unless expressly released and discharged in writing by the Bank. (i) REMEDIES CUMULATIVE AND CONCURRENT. No remedy herein conferred upon or reserved to the Bank is intended to be exclusive of any other remedies provided for in the Financing Documents, and each and every such remedy shall be cumulative, and shall be in addition to every other remedy given hereunder, or under the Financing Documents, or now or hereafter existing at law or in equity or by statute. Every right, power and remedy given by the Financing Documents to the Bank shall be concurrent and may be pursued separately, successively or together against the Borrower or the Collateral or other security for the Borrowers' Obligations or any part thereof, and every right, power and remedy given by the Financing Documents may be exercised from time to time as often as may be deemed expedient by the Bank. (j) NO WAIVER. No delay or omission of the Bank to exercise any right, power or remedy accruing upon the happening of an Event of Default shall impair any such right, power or remedy or shall be construed to be a waiver of any such Event of Default or any acquiescence therein. No delay or omission on the part of the Bank to exercise any remedy hereunder, or acceptance by the Bank of any partial payment on account of the Borrowers' Obligations shall constitute a waiver of any such Event of Default and each of the remedies herein provided shall remain continuously available to the Bank.
