      7. RESTRICTIVE COVENANT. In consideration of Executive's employment,
Executive agrees to the restrictive covenants set forth in Section 3 of his
Change in Control Agreement, which are incorporated herein.

      8. NON-DISCLOSURE OF CONFIDENTIAL INFORMATION.

      A. It is understood that in the course of Executive's employment with
Company, Executive will become acquainted with Company Confidential Information
(as defined below). Executive recognizes that Company Confidential Information
has been developed or acquired at great expense, is proprietary to the Company,
and is and shall remain the exclusive property of the Company. Accordingly,
Executive agrees that he will not, disclose to others, copy, make any use of, or
remove from Company's premises any Company Confidential Information, except as
Executive's duties may specifically require, without the express written consent
of the Board of Directors of the Company, during Executive's employment with the
Company and thereafter until such time as Company Confidential Information
becomes generally known, or readily ascertainable by proper means by persons
unrelated to the Company.

      B. Upon any termination of employment, Executive shall promptly deliver to
the Company the originals and all copies of any and all materials, documents,
notes, manuals, or lists containing or embodying Company Confidential
Information, or relating directly or indirectly to the business of the Company,
in the possession or control of Executive.

      C. "COMPANY CONFIDENTIAL INFORMATION" shall mean confidential, proprietary
information or trade secrets of Company and its subsidiaries and affiliates
including without limitation the following: (1) customer lists and customer
information as compiled by Company; (2) Company's internal practices and
procedures; (3) internal Company financial information; (4) supply of materials
information, including sources and costs, designs, information on land and lot
inventories, and current and prospective projects; (5) strategic planning,
manufacturing, engineering, purchasing, finance, marketing, promotion,
distribution, and selling activities; (6) all other information which is treated
by Company as confidential, include all information having


                                     - 4 -
<PAGE>
independent economic value to Company that is not generally known to, and not
readily ascertainable by proper means by, persons who can obtain economic value
from its disclosure or use. Notwithstanding the foregoing provisions, the
following shall not be considered "Company Confidential Information": (i) the
general skills of the Executive as an experienced entrepreneur and senior
management level employee; (ii) information generally known by senior management
executives within the industry in which the Company operates; (iii) persons,
entities, contacts or relationships of Executive that are also generally known
in the industry; and (iv) information which becomes available on a
non-confidential basis from a source other than Executive which source is not
prohibited from disclosing such confidential information by legal, contractual
or other obligation.

      D. Executive hereby agrees that the periods of time provided for in
Sections 8 and 9 and other provisions and restrictions set forth herein are
reasonable and necessary to protect the Company and its successors and assigns
in the use and employment of the goodwill of the business conducted by
Executive. Executive further agrees that damages cannot compensate the Company
in the event of a violation of Section 8 or 9 and that, if such violation should
occur, injunctive relief shall be essential for the protection of the Company
and its successors and assigns. Accordingly, Executive hereby covenants and
agrees that, in the event any of the provisions of Section 8 or 9 shall be
violated or breached, the Company shall be entitled to obtain injunctive relief
against the party or parties violating such covenants, without bond but upon due
notice, in addition to such further or other relief as may be available at
equity or law. Obtainment of such an injunction by the Company shall not be
considered an election of remedies or a waiver of any right to assert any other
remedies which the Company has at law or in equity. No waiver of any breach or
violation hereof shall be implied from forbearance or failure by the Company to
take action thereof. The prevailing party in any litigation, arbitration or
similar dispute resolution proceeding to enforce this provision will recover any
and all reasonable costs and expenses, including attorneys' fees.

      E. For purposes of Sections 8 and 9, the term "COMPANY" includes Radyne
ComStream Inc. and its subsidiaries and affiliates. For purposes hereunder, an
affiliate shall be deemed to be any corporation or other business entity in
which the Company or its subsidiaries owns a controlling interest.

      9. SEVERABILITY. If any provision of this Agreement is held to be illegal,
invalid, or unenforceable under any applicable law, then such provision will be
deemed to be modified to the extent necessary to render it legal, valid and
enforceable, and if no such modification will make the provision legal, valid
and enforceable, then this Agreement will be construed as if not containing the
provision held to be invalid, and the rights and obligations of the parties will
be construed and enforced accordingly.

      10. ASSIGNMENT BY COMPANY. Nothing in this Agreement shall preclude the
Company from consolidating or merging into or with, or transferring all or
substantially all of its assets to, another corporation or entity that assumes
this Agreement and all obligations and undertakings hereunder. Upon such
consolidation, merger or transfer of assets and assumption, the term "COMPANY"
as used herein shall mean such other corporation or entity, as appropriate, and
this Agreement shall continue in full force and effect.

      11. ENTIRE AGREEMENT. This Agreement, the Change of Control Agreement of
Executive, and any agreements concerning stock options or other benefits, embody
the complete agreement of the parties hereto with respect to the subject matter
hereof and supersede any prior written, or prior or contemporaneous oral,
understandings or agreements between the parties that may have related in any
way to the subject matter hereof. This Agreement may be amended only in writing
executed by the Company and Executive. Notwithstanding the foregoing, nothing in
this Agreement is intended to affect any previous agreements pertaining to the
grant of options to the Executive, including without limitation, provisions in
Executive's prior Change of Control Agreement, providing for acceleration upon a
change-in-control.

      12. GOVERNING LAW. This Agreement and all questions relating to its
validity, interpretation, performance and enforcement, shall be governed by and
construed in accordance with the internal laws, and not the law of conflicts, of
the State of Arizona.

      13. NOTICE. Any notice required or permitted under this Agreement must be
in writing and will be deemed to have been given when delivered personally or by
overnight courier service or three days after being sent by mail, postage
prepaid, at the address indicated below or to such changed address as such

or non-contractual, between the parties hereto arising directly or indirectly

breach of any representation, warranty, agreement, or covenant under this
Agreement, unless mutually settled by the parties hereto, shall be resolved by
binding arbitration in accordance with the Employment Arbitration Rules of the
American Arbitration Association (the "AAA"). Any arbitration shall be conducted
by arbitrators approved by the AAA and mutually acceptable to Company and

arbitrators. If the parties hereto are unable to agree on the arbitrator(s),

arbitrator(s) shall award damages to the prevailing party. The arbitration award
shall be in writing and shall include a statement of the reasons for the award.

party.

      15. WITHHOLDING; RELEASE; NO DUPLICATION OF BENEFITS. All of Executive's

<PAGE>
hereunder (other than salary payments and expense reimbursements through a date
of termination), shall be subject to receipt by the Company from Executive of a
mutually agreeable release, and compliance by Executive with the covenants set
forth in Sections 8 and 9 hereof. If there is any conflict between the
provisions of the Change in Control Agreement and this Agreement, such conflict
shall be resolved so as to provide the greater benefit to Executive. However, in
order to avoid duplication of any monetary benefits, any payments or benefits
due hereunder will be reduced by any payments or benefits provided under the
Change in Control Agreement.

      16. SUCCESSORS AND ASSIGNS. This Agreement is solely for the benefit of
the parties and their respective successors, assigns, heirs and legatees.
Nothing herein shall be construed to provide any right to any other entity or
individual.
