8.       PAYMENT OF PREMIUMS, TAXES, CHARGES, LIENS AND ASSESSMENTS. Debtor agrees to pay, prior to delinquency, all insurance premiums, taxes, charges, liens and assessments against the Collateral and Proceeds, and upon the failure of Debtor to do so, Bank at its option may pay any of them and shall be the sole judge of the legality or validity thereof and the amount necessary to discharge the same. Any such payments made by Bank shall be obligations of Debtor to Bank, due and payable immediately upon demand, and at Bank’s option and subject to any restrictions under applicable law pertaining to usury, together with interest at a rate determined in accordance with the provisions of this Agreement, and shall be secured by the Collateral and Proceeds, subject to all terms and conditions of this Agreement.

9.       EVENTS OF DEFAULT. The occurrence of any of the following shall constitute an "Event of Default" under this Agreement: (a) an Event of Default under the Credit Agreement; (b) any representation or warranty made by Debtor herein shall prove to be incorrect, false or misleading in any material respect when made; (c) Debtor shall fail to observe or perform any obligation or agreement contained herein and with respect to any such default that by its nature can be cured, such default shall continue for a period of thirty (30) days from its occurrence, provided, however, if the default cannot by its nature be cured within the thirty (30) day period or cannot after diligent attempts by Debtor be cured within such thirty (30) day period, and such default is likely to be cured within a reasonable time, then Debtor shall have an additional period determined by Bank (which shall not in any case exceed an additional thirty (30) days) to attempt to cure such default, and within such reasonable time period the failure to cure the default shall not be deemed an Event of Default; (d) any impairment of the rights of Bank in any Collateral or Proceeds, or any attachment or like levy on any property of Debtor that causes a material adverse effect on the Debtor; and (e) Bank, in good faith, believes any or all of the Collateral and/or Proceeds to be in danger of misuse, dissipation, commingling, loss, theft, damage or destruction, or otherwise in jeopardy or unsatisfactory in character or value and such condition will have a material adverse effect on the rights of Bank hereunder.

10.       REMEDIES. Upon the occurrence of any Event of Default, Bank shall have the right to declare immediately due and payable all or any Indebtedness secured hereby and to terminate any commitments to make loans or otherwise extend credit to Debtor. Bank shall have all other rights, powers, privileges and remedies granted to a secured party upon default under the Uniform Commercial Code or the Business and Commerce Code of the jurisdiction identified in Section 18 below, or otherwise provided by law, including without limitation, the right (a) to contact all persons obligated to Debtor on any Collateral or Proceeds and to instruct such persons to deliver all Collateral and/or Proceeds directly to Bank, and (b) to sell, lease, license or otherwise dispose of any or all Collateral. In addition to any other remedies set forth in this Agreement, Debtor authorizes Bank to engage in “electronic self-help” as defined in and in accordance with applicable law. All rights, powers, privileges and remedies of Bank shall be cumulative. No delay, failure or discontinuance of Bank in exercising any right, power, privilege

or remedy hereunder shall affect or operate as a waiver of such right, power, privilege or remedy; nor shall any single or partial exercise of any such right, power, privilege or remedy preclude, waive or otherwise affect any other or further exercise thereof or the exercise of any other right, power, privilege or remedy. Any waiver, permit, consent or approval of any kind by Bank of any default hereunder, or any such waiver of any provisions or conditions hereof, must be in writing and shall be effective only to the extent set forth in writing. It is agreed that public or private sales or other dispositions, for cash or on credit, to a wholesaler or retailer or investor, or user of property of the types subject to this Agreement, or public auctions, are all commercially reasonable since differences in the prices generally realized in the different kinds of dispositions are ordinarily offset by the differences in the costs and credit risks of such dispositions. While an Event of Default exists: (a) Debtor will deliver to Bank from time to time, as requested by Bank, current lists of all Collateral and Proceeds; (b) Debtor will not dispose of any Collateral or Proceeds except on terms approved by Bank; (c) at Bank's request, Debtor will assemble and deliver all Collateral and Proceeds, and books and records pertaining thereto, to Bank at a reasonably convenient place designated by Bank; and (d) Bank may, without notice to Debtor, enter onto Debtor's premises and take possession of the Collateral. With respect to any sale or other disposition by Bank of any Collateral subject to this Agreement, Debtor hereby expressly grants to Bank the right to sell such Collateral using any or all of Debtor's trademarks, trade names, trade name rights and/or proprietary labels or marks. Debtor further agrees that Bank shall have no obligation to process or prepare any Collateral for sale or other disposition. In addition, Bank shall have the right to file against each individual government contract of Borrower, Guarantor and/or its subsidiaries, as applicable, in accordance with the terms of the Assignment of Claims Act of 1940, following and during the continuance of an Event of Default.

11.       DISPOSITION OF COLLATERAL AND PROCEEDS; TRANSFER OF INDEBTEDNESS. In disposing of Collateral hereunder, Bank may disclaim all warranties of title, possession, quiet enjoyment and the like. Any proceeds of any disposition of any Collateral or Proceeds, or any part thereof, may be applied by Bank to the payment of expenses incurred by Bank in connection with the foregoing, including reasonable attorneys' fees, and the balance of such proceeds may be applied by Bank toward the payment of the Indebtedness in such order of application as Bank may from time to time elect. Upon the transfer of all or any part of the Indebtedness, Bank may transfer all or any part of the Collateral or Proceeds and shall be fully discharged thereafter from all liability and responsibility with respect to any of the foregoing so transferred, and the transferee shall be vested with all rights and powers of Bank hereunder with respect to any of the foregoing so transferred; but with respect to any Collateral or Proceeds not so transferred, Bank shall retain all rights, powers, privileges and remedies herein given.

12.       STATUTE OF LIMITATIONS. Until all Indebtedness shall have been paid in full and all commitments by Bank to extend credit to Debtor have been terminated, the power of sale or other disposition and all other rights, powers, privileges and remedies granted to Bank hereunder shall, to the extent permitted by law, continue to exist and may be exercised by Bank at any time and from time to time irrespective of the fact that the Indebtedness or any part thereof may have become barred by any statute of limitations, or that the personal liability of Debtor may have ceased, unless such liability shall have ceased due to the payment in full of all Indebtedness secured hereunder.

13.       MISCELLANEOUS. When there is more than one Debtor named herein: (a) the word "Debtor" shall mean all or any one or more of them as the context requires; (b) the obligations of each Debtor hereunder are joint and several; and (c) until all Indebtedness shall have been paid in full, no Debtor shall have any right of subrogation or contribution, and each

Debtor hereby waives any benefit of or right to participate in any of the Collateral or Proceeds or any other security now or hereafter held by Bank. Debtor hereby waives any right to require Bank to (i) proceed against Debtor or any other person, (ii) marshal assets or proceed against or exhaust any security from Debtor or any other person, (iii) perform any obligation of Debtor with respect to any Collateral or Proceeds, and (iv) make any presentment or demand, or give any notices of any kind, including without limitation, any notice of nonpayment or nonperformance, protest, notice of protest, notice of dishonor, notice of intention to accelerate or notice of acceleration hereunder or in connection with any Collateral or Proceeds. Debtor further waives any right to direct the application of payments or security for any Indebtedness of Debtor or indebtedness of customers of Debtor.

14.       NOTICES. All notices, requests and demands required under this Agreement must be in writing, addressed to Bank at the address specified in any other loan documents entered into between Debtor and Bank and to Debtor at the address of its chief executive office (or principal residence, if applicable) specified below or to such other address as any party may designate by written notice to each other party, and shall be deemed to have been given or made as follows: (a) if personally delivered, upon delivery; (b) if sent by mail, upon the earlier of the date of receipt or three (3) days after deposit in the U.S. mail, first class and postage prepaid; and (c) if sent by telecopy, upon receipt.

15.       COSTS, EXPENSES AND ATTORNEYS' FEES. Debtor shall pay to Bank immediately upon demand the full amount of all payments, advances, charges, costs and expenses, including, to the extent permitted by applicable law, reasonable attorneys' fees (to include outside counsel fees), expended or incurred by Bank in connection with (a) the perfection and preservation of the Collateral or Bank's interest therein, and (b) the realization, enforcement and exercise of any right, power, privilege or remedy conferred by this Agreement, whether or not suit is brought or foreclosure is commenced, and where suit is brought, whether incurred at the trial or appellate level, in an arbitration proceeding or otherwise, and including any of the foregoing incurred in connection with any bankruptcy proceeding (including without limitation, any adversary proceeding, contested matter or motion brought by Bank or any other person) relating to Debtor or in any way affecting any of the Collateral or Bank's ability to exercise any of its rights or remedies with respect thereto. Notwithstanding anything in this Agreement to the contrary, reasonable attorneys’ fees shall not exceed the amount permitted by law. Whenever in this Agreement Debtor is obligated to pay for the attorneys' fees of Bank, or the phrase "reasonable attorneys' fees" or a similar phrase is used, it shall be Debtor's obligation to pay the attorneys' fees actually incurred or allocated, at standard hourly rates, without regard to any statutory interpretation, which shall not apply, Debtor hereby waiving the application of any such statute. Subject to any restrictions under applicable law pertaining to usury, all of the foregoing shall be paid by Debtor with interest from the date of demand until paid in full at a rate per annum equal to the greater of any default rate applicable to the Borrower’s outstanding obligations under the Credit Agreement, or Bank’s Prime Rate in effect from time to time.

16.       SUCCESSORS; ASSIGNS; AMENDMENT. This Agreement shall be binding upon and inure to the benefit of the administrators, legal representatives, successors and assigns of the parties, and may be amended or modified only in writing signed by Bank and Debtor.

17.       SEVERABILITY OF PROVISIONS. If any provision of this Agreement shall be held to be prohibited by or invalid under applicable law, such provision shall be ineffective only

to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or any remaining provisions of this Agreement.

18.       GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, but giving effect to federal laws applicable to national banks.
