If requested by the Secured Party, Digilog will keep any of the Digilog Assets insured against fire, damage, theft, business interruption and such other risks as the Secured Party may require. Such insurance will be in such amounts, with such companies, for such periods of time, and in such form as shall be satisfactory to the Secured Party. Any and all such insurance policies are to be made payable to the Secured Party in the event of loss, under a standard non-contributory "mortgages", "Secured Party's", or "secured party" clause and shall contain a breach of warranty provision acceptable to the Secured Party which shall establish the Secured Party's right to be paid the insurance proceeds irrespective of any action, inaction, breach of warranty or conditions, or negligence of Digilog or any other person or entity with respect to such policies.

All such policies shall provide for a minimum of thirty (30) days' written notice to the Secured Party prior to cancellation. Digilog hereby appoints the Secured Party as its attorney-in-fact, to file claims under any such insurance policies, to receive, receipt and give acquittance for any payments that may be payable to Digilog thereunder, and to execute any and all endorsements, receipts, releases, assignments, reassignments or other documents that may be necessary to effect the collection, compromise or settlement of any claims under any such insurance policies, which power of attorney shall be deemed coupled with an interest and irrevocable so long as the Secured Party shall have a security interest in any of the Digilog Assets pursuant to this Agreement. If Digilog shall fail to procure such insurance so requested or to pay any premium with respect thereto, then the Secured Party may, at its discretion, procure such insurance or pay such premium, and any costs so incurred by the Secured Party shall constitute a part of the Liabilities secured hereby. The Secured Party may apply the proceeds of any such insurance policy received by it to the payment of any Liabilities, whether due or not due, in such order of application as the Secured Party shall determine. Digilog shall promptly furnish the Secured Party with certificates or other evidence satisfactory to it indicating compliance with the foregoing insurance requirements. Section 5. Power of Attorney.

Section 6. Use of Collateral. Until an Event of Default shall have occurred, the Debtors may, unless otherwise provided in this Agreement, at their own expense, sell, lease, furnish under contract of service, use, consume, administer, manage and otherwise deal with any of the respective Collateral owned by it in the ordinary course of business consistent with such Debtor's business practices. Section 7. Performance of the Debtors' Obligations. The Secured Party may from time to time, at its sole discretion, perform any agreement of either Debtor hereunder which such Debtor shall fail to perform and take any other action that the Secured Party deems necessary for the maintenance or preservation of any of the Collateral or its interest therein (including, without limitation, the discharge of taxes or liens of any kind against the Collateral), and each of the Debtors agrees to promptly reimburse the Secured Party, on demand, for all expenses incurred in connection with the foregoing, together with interest thereon at the rate 18% per annum, or at the highest rate permitted by law, whichever is less, from the date incurred until the date of reimbursement.

Section 10. Notice of Intended Disposition. If any notification of intended disposition of any Collateral is required by law, reasonable notification shall be deemed given if written notice is deposited in the U.S. Mail, first class or certified postage prepaid, addressed to the applicable Debtor and such other persons or entities as the Secured Party deems to be appropriate, stating the time and place of any public sale or the time after which any private sale or disposition is to be made, at least five (5) days prior thereto.

The proceeds of any disposition of the Collateral shall be applied in the following order: (i) first, to pay all costs and expenses associated with the retaking, holding, preparation and disposition of the Collateral on behalf of the Secured Party; (ii) then, to pay attorneys' fees and any other applicable costs or expenses owed by either of the Debtors to the Secured Party under this Agreement, the Guarantee, the Line of Credit Agreement or under the Note; (iii) next, to pay all accrued but unpaid interest accrued upon the Liabilities in such order as the Secured Party may determine at its discretion; and (iv) finally, to all unpaid principal outstanding under the Liabilities, whether or not due and payable, in such order as the Secured Party may determine at its sole discretion.

Section 12. Security Interest Absolute. This Agreement and the lien, security interest and security title conveyed hereunder shall remain in full force and effect without regard to, and shall not be released, suspended, terminated, modified or otherwise affected by any circumstance or occurrence whatsoever, including without limitation any of the following (whether or not the Debtors consent thereto or have notice thereof): A. any change in or waiver of the time, place or manner of payment, or any other term, of the Line of Credit Agreement, the Note or the Guarantee or any waiver of or any renewal, extension, increase, amendment or modification of or addition or supplement to or deletion from, or any other action or inaction under or in respect of, the Line of Credit Agreement, the Note or the Guarantee or any other document, instrument or agreement referred to therein or any assignment or transfer of the any rights or obligations under Line of Credit Agreement, the Note or the Guarantee; B. any bankruptcy, insolvency, liquidation or other like proceeding or occurrence relating to the Secured Party or either Debtor; C. any failure of the Secured Party to exercise any right or remedy against any person or entity other than Debtors; D. any other act or failure to act by the Secured Party which may adversely affect either Debtor; or E. any other circumstance which might otherwise constitute a defense against, or a legal or equitable discharge of, the Debtors' liability under this Agreement, the Line of Credit Agreement, the Note or the Guarantee, or the Secured Party's lien, security interest or security title hereunder. Section 13. Miscellaneous. A. The Secured Party shall be deemed to have exercised reasonable care in the custody and preservation of any of the Collateral in its possession if it takes such action for that purpose as either of the Debtors reasonably requests in writing, but failure of the Secured Party to comply with any such request shall not of itself be deemed a failure to exercise reasonable care, and no failure of the Secured Party to preserve or protect any rights with respect to such Collateral against prior parties, or to do any act with respect to the preservation of such Collateral not so requested by the Debtors, shall be deemed a failure to exercise reasonable care in the custody or preservation of such Collateral.
