SECURITY AGREEMENT 1. GRANT. For value received, Datametrics, Inc., a Delaware corporation, ("DMC"), in this security agreement (this "SECURITY AGREEMENT"), grants to Adrien A.

ATTACHMENT AND OBLIGATION SECURED. The security interest created by this Security Agreement will attach immediately upon execution of this Security Agreement by DMC, and will secure all of DMC's obligations to make any payments to Secured Party under the Severance Package as agreed by DMC in Section 6.1 of the Amended Employment Agreement entered into between DMC and Secured Party on August 12, 1997. Said security interest is issued concurrently with an identical security interest issued to Daniel P. Ginns, both such security interests ranking pari passu to each other. Except for said security interests granted by DMC pursuant to the agreements described on Exhibit E of the foregoing Amended Employment Agreement in favor of (1) Imperial Bank and (2) the holders of certain Senior Subordinated Secured Debentures, DMC has not granted any perfected security interests that now exists and are continuing.

DEFAULT. Should DMC fail to perform any provision of this Security Agreement or should DMC fail to pay any obligation secured by this Security Agreement as it becomes due, DMC shall be deemed to be in default of this Security Agreement under Division 9 of the Uniform Commercial Code of California and under the corresponding provisions of the Uniform Commercial Code of any other state. In such event, Secured Party will have all the rights and remedies afforded to a secured party under Division 9 of the Uniform Commercial Code of California and under the corresponding provisions of the Uniform Commercial Code of any other state on the date of this Security Agreement and may, in connection therewith and subject to the rights of the Senior Secured Lenders, also, but without limitation: - 1 - a. Enter the premises to assemble and take possession of the Collateral; and b. Enter the premises, render the Collateral, if equipment, usable and dispose of it in the manner provided by the Uniform Commercial Code of California or by the Uniform Commercial Code of any other state. 6. FINANCING STATEMENT. Concurrent with the execution of this Security Agreement, the parties hereto, DMC and Secured Party, shall execute any financing statement or statements required to perfect the security interest created by this Security Agreement. 7. WAIVER. Neither the acceptance of any partial benefits and/or partial payments provided under the Severance Package by Secured party, nor Secured Party's failure to exercise any of his rights or remedies on default by DMC, shall be a waiver of the default, a modification of this Security Agreement or of DMC's obligations under this Security Agreement, or a waiver of any subsequent default by DMC. 8. NOTICES. Except as expressly provided for in this Security Agreement or by law, any and all notices or other communications required or permitted by this Security Agreement or by law to be served on, given to, or delivered to either party hereto, shall be in writing and shall be deemed duly served, given, delivered, and received when personally delivered to the party to whom it is directed, or in lieu of such personal delivery, when deposited in the United States mail, first class postage prepaid, addressed to Secured Party or to DMC at their respective addresses set forth on the Schedule of Collateral attached hereto.

If any action at law or in equity is brought to enforce or interpret the provisions of this Agreement or any other agreement or instrument provided for herein, the prevailing party in such action shall be entitled to recover as an element of such party's costs of suit, and not as damages actual attorneys' fees to be fixed by the court. The prevailing party shall be the party who is entitled to recover its costs of suit as ordered by the court or by applicable law or court rules. A party not entitled to recover its costs shall not recover attorneys' fees. 10. SUCCESSORS AND ASSIGNS. This Security Agreement shall be binding upon and shall inure to the benefit of the parties hereto, their successors and assigns, but shall not be assigned, transferred or set over in whole or in part by any party without the prior written consent of each party. 11. GOVERNING LAW.

SEVERABILITY. Any provision of this Security Agreement which is held to be invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity or uneforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction. 13. COUNTERPARTS. This Security Agreement may be executed in several counterparts and also so executed will constitute one Security Agreement, binding on all the Parties. 14. SOLE AND ONLY AGREEMENT.
