     3(a) through the remaining term of this Agreement.

     (b)  Termination Events. The occurrence of any of the following events
     during the term of the Agreement shall also constitute Termination Without

     Mr. Amjadi's base salary is reduced for any reason without his consent;
     (ii) the Company is taken over, sold, or involved in a merger or
     acquisition of any kind, and the same salary is not offered to him for the
     remaining term of this agreement.

     (c)  Termination With Cause. Termination for cause shall mean only
     termination for gross or serious financial or felony misconduct by Mr.
     Amjadi in connection with his employment. Non-performance on the Company's
     business objectives shall not be deemed grounds for termination with cause.
     If terminated with cause, the payment provision defined in Paragraph 4(a)

5.   PROPRIETARY INFORMATION AND NON-COMPETE AGREEMENT

     (a)  Mr. Amjadi acknowledges that during the term of the Agreement he will
     have access to and become familiar with various trade secrets, confidential
     and proprietary information of the Company, that such information is the
     property of the Company and that it shall not be used or disclosed during
     the term of his employment or for one year thereafter.

     (b)  Mr. Amjadi also agrees that for period of one year subsequent to his

     in any way, by individuals, companies, entities or interests that compete
     directly with the Company on any of the products that the Company has
     developed or is in the process of developing at the time of his
     termination. Subsequent to this one year non-compete period, Mr. Amjadi
     shall continue to protect as confidential and not use any intellectual
     property belonging to the Company, but may use other information he
     acquired as an executive of the Company.

6.   ASSIGNMENT. The parties acknowledge that a successor to the Company under
a sale, merger or acquisition shall be bound by all of the terms and conditions
of this Agreement.

<PAGE>   5
7.   SEVERABILITY. If any provision of this Agreement is adjudged by any court
to be void or unenforceable in whole or in part, this adjudication shall not
effect the validity of the remainder of the Agreement. Each provision,
paragraph and subpart of this Agreement is separable from every other
provision, paragraph and subpart and constitutes a separate and distinct
covenant.

8.   APPLICABLE LAW. This Agreement shall be construed in accordance with the
laws of the State of Maryland.

9.   COMPLETE AGREEMENT. This Agreement embodies all the terms and conditions
as agreed to between the parties. Mr. Amjadi acknowledges that he has not
relied on any warranties or representations or promises except as set forth in
this document. This Agreement may be changed, amended or superseded only by an
agreement in writing signed by the parties.

10.  ARBITRATION

     (a)  Mandatory Arbitration. The parties agree that any dispute under this
     Agreement, including termination, shall be subject to mandatory arbitration
     pursuant to the rules of the American Arbitration Association. The parties
     acknowledge that arbitration is the sole remedy available to them regarding
     their claims under this Agreement. Provided, however, that if the Company
     fails to comply with its obligations in paragraph 4(a) or (b) Mr. Amjadi
     shall have the right to seek injunctive relief to enforce the Agreement.
     Mr. Amjadi and the Company otherwise agree to waive all fights to litigate
     disputes under this Agreement in federal or state court. This provision to
     arbitrate any dispute in connection with the terms and conditions of this
     Agreement shall survive termination of this Agreement.

     (b)  Arbitration Procedures. Unless the parties to the arbitration agree
     otherwise, the arbitration shall take place in Montgomery County, Maryland.
     The arbitration award shall be final and binding upon the parties and may
     be entered in any court having jurisdiction. The parties will use a single
     arbitrator and shall divide the costs of the arbitration equally. Each
     party shall bear its own attorney's fees and costs for the arbitration.
