            Re:   Change in Control Agreement

Dear Rich:

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 June 18, 2003 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 twenty-four (24) months
                  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;



Richard P. Johnson - Change in Control Agreement (continued)


         (d)      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;

         (e)      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, and thereby
                  result in an excise tax payable by you, then at least 30 days
                  prior to the due date of any such tax, the Company shall pay
                  you an amount equal to the tax (together with any tax on such
                  payment).

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


                                   Page 2 of 7


Richard P. Johnson - Change in Control Agreement (continued)


                  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.

         (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,
         certified or registered, in the United States mail, postage prepaid,
         addressed as follows:

         grants or Company plans or policies, to which you are subject, this
         Agreement constitutes and embodies the full and complete understanding
         and agreement of the Company and you with respect to your employment by

         jurisdiction thereof. The arbitrator(s) shall possess the powers to
         issue mandatory orders and restraining orders in connection with such
         arbitration. The expenses of the arbitration shall be borne by the
         losing party unless otherwise allocated by the arbitrator(s). This
         agreement to arbitrate shall be specifically enforceable under the
         prevailing arbitration law. During the continuance of any arbitration
         proceedings, the parties shall continue to perform their respective
         obligations under this Agreement. Nothing in this Agreement shall
         preclude the Company or any affiliate or successor from seeking
         equitable relief, including injunction or specific performance, in any
         court having jurisdiction, in connection with the non-compete
         provisions herein and any obligations of confidentiality.

                  particular the non-competition provisions of Paragraph 3,

         (b)      any reasonable and lawful policies or procedures of the
                  Company relating to employee severances; and

                  satisfactory to the Company of any and all claims that you may
                  have against the Company or related persons, except for (i)
