         Re:      Your Change in Control Agreement

Dear Steve:

         Upon execution by you, this letter will constitute your Change in
Control Agreement ("Agreement") with Radyne ComStream Corp., (the "Company").

1.       Term. This Agreement will become effective March 14, 2002 and will
         terminate when you terminate your employment with the Company.

2.       Termination in Connection with a Change in Control. In the event of a
         Change of Control (as defined in the Company's Long-Term Incentive
         Plan, a copy of which definition is attached), you will be entitled to
         receive the following:

         (a)      Immediately prior to the effective date of a Change of
                  Control, all stock options granted to you and not otherwise
                  vested shall vest and become exercisable by you for a minimum
                  of 90 days (or, if longer, the term thereof) so that you may
                  participate in the Change of Control transaction to the
                  fullest extent feasible, provided, however, that if the
                  acceleration of your options would cause a charge to the
                  Company's earnings, then at the Company's option it may offer
                  you a consulting position for the term of your options during
                  which your options would continue to vest;

         (b)      Upon any termination of your employment after a Change of
                  Control, for a period of eighteen months from the date of your
                  termination, the Company will pay for the COBRA benefits due
                  you;

         (c)      If you are terminated without Cause (as defined in the
                  attachment), or you resign for Good Reason (as set forth in
                  the attachment) within the first year following the Change in
                  Control, upon such event you shall be paid in a lump sum an
                  amount equal to two times your current salary from the
                  Company;

         (d)      If you are terminated without Cause, or you resign for Good
                  Reason (as set forth in the attachment) within the second year
                  following the Change in Control, upon such event you shall be
                  paid in a lump sum an amount equal to one times your current
                  salary;
<PAGE>
         (e)      Upon a Change in Control, funds sufficient to satisfy your
                  Change of Control payments in (c) or (d) above shall be
                  deposited into a trust account maintained by a major financial
                  institution and shall be paid to you upon your written notice
                  to the Trustee to the effect that you have been terminated
                  without Cause or you have resigned for Good Reason. The
                  Company shall not have the ability to prevent such payment
                  from the trust upon your notice, but shall have the right to
                  dispute your termination as provided in Section 8 below, and
                  pursue all other available remedies;

         (f)      To the extent that the benefits provided to you upon a Change
                  in Control would exceed the amount deductible pursuant to
                  Section 280G of the Internal Revenue Code (or any successor
                  law), or the rules and regulations thereunder, then the amount
                  of benefits payable to you will be limited to the maximum
                  amount permitted under Section 280G, with the benefits that
                  are reduced to be selected by you.

3.       Covenant Not to Compete.

         (a)      For a period of 1 year from any termination of your
         employment, (or, if later, upon conclusion of your service as a
         consultant), you shall not, directly or indirectly, for your own
         benefit or for, with or through any other individual, firm,
         corporation, partnership or other entity, whether acting in an
         individual, fiduciary or other capacity, own, manage, operate, control,
         advise, invest in (except as a 1% or less shareholder of a public
         company), loan money to, or participate or assist in the ownership,
         management, operation or control of or be associated as a director,
         officer, employee, partner, consultant, advisor, creditor, agent,
         independent contractor or otherwise with, or acquiesce in the use of
         your name by, any business enterprise that is in direct competition
         with the Company or any subsidiary within the United States of America
         or any other country that the Company conducts business at the time of
         your termination.

         (b)      In addition to the foregoing, at all times during the period
         of your employment and for 1 year after any termination thereof (or, if
         later, upon conclusion of your services as a consultant), you will not,
         directly or indirectly (as described above), for your benefit or for,
         with or through any business, hire, employ, solicit, or otherwise
         encourage or entice any of the Company's (or subsidiary's) employees or
         consultants to leave or terminate their employment with the Company.

         (c)      You and the Company consider the restrictions contained in
         subparagraphs (a) and (b) above to be reasonable for the purpose of
         preserving the Company's proprietary rights and interests. If a court
         makes a final judicial determination that any such restrictions are
         unreasonable or otherwise unenforceable against you, you and the
         Company hereby authorize such court to amend this Agreement so as to
         produce the broadest, legally enforceable agreement, and for this
         purpose the restrictions on time period, geographical area and scope of
         activities set forth in subparagraphs (a) and (b) above are divisible;
         if the court refuses to do so, you and the Company hereto agree to
         modify the provisions held to be unenforceable to preserve each party's
         anticipated benefits thereunder to the maximum extent legal.

                                       2

         (d)      You acknowledge and agree that the Company's remedies at law
         for breach or threatened breach of any of the provisions of this
         Paragraph would be inadequate. Therefore, you agree that in the event
         of a breach or threatened breach by you of the provisions in this
         Paragraph, the Company shall be entitled to, in addition to its
         remedies at law and without posting any bond, equitable relief in the
         form of specific performance, a temporary restraining order, a
         temporary or permanent injunction, or any other equitable remedy that
         may then be available.

4.       Personal Rights and Obligations. This Agreement and all rights and
         obligations hereunder are personal and shall not be assignable by
         either you or the Company except as provided in this subparagraph, and
         any purported assignment in violation thereof shall be null and void.
         Any person, firm or corporation succeeding to the business of the
         Company by merger, consolidation, purchase of assets or otherwise,
         shall assume by contract or operation of law the obligations of the
         Company hereunder and in such a case you shall continue to honor this
         Agreement with such business substituted for the Company as the
         employer.

5.       Notices. Any notice, election or communication to be given under this
         Agreement shall be in writing and delivered in person or deposited,

         grants or Company plans or policies, to which you are subject, this
         Agreement constitutes and embodies the full and complete understanding
