In order to receive Credit Accommodations under the Loan Facility, Borrower shall have delivered to Lender an Export-Related Borrowing Base Certificate as frequently as required by Lender but at least within the past thirty (30) calendar days and a copy of the Export Order(s) (or, for Revolving Loan Facilities, if permitted by Lender, a written summary of the Export Orders) against which Borrower is requesting Credit Accommodations. If Lender permits summaries of Export Orders, Borrower shall also deliver promptly to Lender copies of any Export Orders requested by Lender. In addition, so long as there are any Credit Accommodations outstanding under the Loan Facility, Borrower shall deliver to Lender at least once each month no later than the twentieth (20th) day of such month or more frequently as required by the Loan Documents, an Export-Related Borrowing Base Certificate.

Borrower represents and warrants that it owns, or is licensed to use, all General Intangibles necessary to conduct its business as currently conducted except where the failure of Borrower to own or license such General Intangibles could not reasonably be expected to have a Material Adverse Effect.

2.11 Notice of Certain Events. Borrower shall promptly, but in any event within five (5) Business Days, notify Lender in writing of the occurrence of any of the following:

(a) Borrower or any Guarantor (i) applies for, consents to or suffers the appointment of, or the taking of possession by, a receiver, custodian, trustee, liquidator or similar fiduciary of itself or of all or a substantial part of its property or calls a meeting of its creditors, (ii) admits in writing its inability, or is generally unable, to pay its debts as they become due or ceases operations of its present business, (iii) makes a general assignment for the benefit of creditors, (iv) commences a voluntary case under any state or federal bankruptcy laws (as now or hereafter in effect), (v) is adjudicated as bankrupt or insolvent, (vi) files a petition seeking to take advantage of any other law providing for the relief of debtors, (vii) acquiesces to, or fails to have dismissed within thirty (30) days, any petition filed against it in any involuntary case under such bankruptcy laws, or (vii) takes any action for the purpose of effecting any of the foregoing;

2.12 Insurance. Borrower will at all times carry property, liability and other insurance, with insurers acceptable to Lender, in such form and amounts, and with such deductibles and other provisions, as Lender shall require, and Borrower will provide evidence of such insurance to Lender, so that Lender is satisfied that such insurance is, at all times, in full force and effect. Each property insurance policy shall name Lender as loss payee and shall contain a lender’s loss payable endorsement in form acceptable to Lender and each liability insurance policy shall name Lender as an additional insured. All policies of insurance shall provide that they may not be cancelled or changed without at least ten (10) days’ prior written notice to Lender and shall otherwise be in form and substance satisfactory to Lender. Borrower will promptly deliver to Lender copies of all reports made to insurance companies.

2.13 Taxes. Borrower has timely filed all tax returns and reports required by applicable law, has timely paid all applicable taxes, assessments, deposits and contributions owing by Borrower and will timely pay all such items in the future as they became due and payable. Borrower may, however, defer payment of any contested taxes; provided, that Borrower (a) in good faith contests Borrower’s obligation to pay such taxes by appropriate proceedings promptly and diligently instituted and conducted; (b) notifies Lender in writing of the commencement of, and any material development in, the proceedings; (c) posts bonds or takes any other steps required to keep the contested taxes from becoming a Lien upon any of the Collateral; and (d) maintains adequate reserves therefor in conformity with GAAP.

Borrower represents and warrants that it has complied in all material respects with all provisions of all applicable laws and regulations, including those relating to Borrower’s ownership of real or personal property, the conduct and licensing of Borrower’s business, the payment and withholding of taxes, ERISA and other employee matters, safety and environmental matters.

2.15 Negative Covenants. Without the prior written consent of Ex-Im Bank and Lender, Borrower shall not (a) merge, consolidate or otherwise combine with any other Person; (b) acquire all or substantially all of the assets or capital stock of any other Person; (c) sell, lease, transfer, convey, assign or otherwise dispose of any of its assets, except for the sale of Inventory in the ordinary course of business and the disposition of obsolete equipment in the ordinary course of business; (d) create any Lien on the Collateral except for Permitted Liens; (e) make any material changes in its organizational structure or identity; or (f) enter into any agreement to do any of the foregoing.

2.16 Reborrowings and Repayment Terms. (a) If the Loan Facility is a Revolving Loan Facility, provided that Borrower is not in default under any of the Loan Documents, Borrower may borrow, repay and reborrow amounts under the Loan Facility until the close of business on the Final Disbursement Date. Unless the Revolving Loan Facility is renewed or extended by Lender with the consent of Ex-Im Bank, Borrower shall pay in full the outstanding Loan Facility Obligations and all accrued and unpaid interest thereon no later than the first Business Day after the Final Disbursement Date.

(b) If the Loan Facility is a Transaction Specific Loan Facility, Borrower shall, within two (2) Business Days of the receipt thereof, pay to Lender (for application against the outstanding Loan Facility Obligations and accrued and unpaid interest thereon) all checks, drafts, cash and

other remittances it may receive in payment or on account of the Export-Related Accounts Receivable or any other Collateral, in precisely the form received (except for the endorsement of Borrower where necessary). Pending such deposit, Borrower shall hold such amounts in trust for Lender separate and apart and shall not commingle any such items of payment with any of its other funds or property.

2.17 Cross Default. Borrower shall be deemed in default under the Loan Facility if Borrower fails to pay when due any amount payable to Lender under any loan or other credit accommodations to Borrower whether or not guaranteed by Ex-Im Bank.

2.18 Munitions List. If any of the Items are articles, services, or related technical data that are listed on the United States Munitions List (part 121 of title 22 of the Code of Federal Regulations), Borrower shall send a written notice promptly, but in any event within five (5) Business Days, of Borrower learning thereof to Lender describing the Items(s) and the corresponding invoice amount.

2.19 Suspension and Debarment, etc. On the date of this Agreement neither Borrower nor its Principals are (a) debarred, suspended, proposed for debarment with a final determination still pending, declared ineligible or voluntarily excluded (as such terms are defined under any of the Debarment Regulations referred to below) from participating in procurement or nonprocurement transactions with any United States federal government department or agency pursuant to any of the Debarment Regulations or (b) indicted, convicted or had a civil judgment rendered against Borrower or any of its Principals for any of the offenses listed in any of the Debarment Regulations. Unless authorized by Ex-Im Bank, Borrower will not knowingly enter into any transactions in connection with the Items with any person who is debarred, suspended, declared ineligible or voluntarily excluded from participation in procurement or nonprocurement transactions with any United States federal government department or agency pursuant to any of the Debarment Regulations. Borrower will provide immediate written notice to Lender if at any time it learns that the certification set forth in this Section 2.19 was erroneous when made or has become erroneous by reason of changed circumstances.
