- --------------------------------------------------------------------------------------------------------


      The exercise price of the new option(s) will be equal to the closing sale
price of our common stock as reported on the Nasdaq National Market on the new
option grant date (or the last trading day before the new option grant date, if
the market for trading in our stock is closed on such date). Accrued vesting
will remain consistent with the original grant once the new option is approved.

      I sell, assign, and transfer to, or upon the order of, Radyne ComStream,
all right, title and interest in and to all of the options that I am tendering
under this letter. I acknowledge that Radyne ComStream has advised me to consult
with my own advisors as to the consequences of participating or not
participating in the Offer. I agree that this letter is an amendment to any
option agreements that govern my tendered options.

      I represent and warrant that I have full power and authority to tender my
options and that, when and to the extent the options are accepted for exchange
by Radyne ComStream, the options will be free and clear of all security
interests, liens, restrictions, charges, encumbrances, conditional sales
agreements, or other obligations relating to their sale or transfer, other than
pursuant to the applicable option agreement. Furthermore, my tendered options
will not be subject to any adverse claims. Upon request, I will execute and
deliver any additional


                                       2

documents deemed by Radyne ComStream to be necessary or desirable to complete
the exchange of the options I am tendering.

      All authority that I confer or agree to confer will not be affected by,
and will survive, my death or incapacity, and all of my obligations under this
letter and the Offer will be binding upon my heirs, personal representatives,
successors and assigns. Except as stated in the Offer, this tender is
irrevocable.

      By execution hereof, I understand that tenders of options pursuant to the
procedure described in Section 3 of the Offer to Exchange and in the
instructions to this letter will constitute my acceptance of the terms and
conditions of the Offer. Radyne ComStream's acceptance for exchange of my
tendered options will constitute a binding agreement between Radyne ComStream
and me upon the terms and subject to the conditions of the Offer.

      I acknowledge that the new options that I will receive: (1) will not be
granted until on or about the first business day that is at least six months and
one day after the date my old options are canceled and (2) will be subject to
the terms and conditions set forth in a new option agreement between Radyne
ComStream and me that will be forwarded to me after the grant of the new
options. I also acknowledge that I must be an employee of Radyne ComStream from
the date I tender my options through the date the new options are granted and
otherwise be eligible under the Radyne ComStream Inc. 1996 Incentive Stock
Option Plan (the "1996 Plan") or 2000 Long-Term Incentive Plan (the "2000
Plan"), as applicable on the date the new options are granted in order to
receive new options. I further acknowledge that, if I do not remain an employee,
I will not receive any new options or any other consideration for my tendered
options that are accepted for exchange pursuant to the Offer.

      The name and social security number of the registered holder of the
tendered options appear below exactly as they appear on the option agreement or
agreements governing those options. The table on page 1 contains for each
tendered option the grant date, the exercise price, and the total number of
shares of common stock subject to the option I am tendering. I understand that I
may tender all of my options outstanding under Radyne ComStream's 1996 Plan and
2000 Plan having exercise prices ranging between $6.00 and $8.25 and between
$14.00 and $14.63 per share and that I am not required to tender any options in
the Offer. I understand that Radyne ComStream will not accept partial tenders of
individual option grants. The term "Expiration Date" means 12:00 midnight,
Mountain Standard Time, on January 22, 2003. The Expiration Date may be extended
by Radyne ComStream, during which the Offer will remain open.

      I recognize that, under certain circumstances set forth in the Offer to
Exchange, Radyne ComStream may terminate or amend the Offer and postpone its
acceptance and cancellation of any options tendered for exchange. In any such
event, I understand that the tendered options delivered with this letter but not
accepted for exchange will be returned to me at the address indicated below.

      THE OFFER IS NOT BEING MADE TO (NOR WILL TENDERS OF OPTIONS BE ACCEPTED
FROM OR ON BEHALF OF) HOLDERS IN ANY JURISDICTION IN WHICH THE MAKING OR
ACCEPTANCE OF THE OFFER WOULD NOT BE IN COMPLIANCE WITH THE LAWS OF SUCH
JURISDICTION.

from the commencement of the Offer, you may withdraw your tendered Options at

a written notice of withdrawal with the required information to Radyne ComStream
while you still have the right to withdraw the tendered options. Withdrawals may
not be rescinded and any options withdrawn will thereafter be deemed not
properly tendered for purposes of the Offer unless such withdrawn options are
properly re-tendered prior to the Expiration Date by following the procedures
described above.

      Radyne ComStream will not accept any alternative, conditional or
contingent tenders. All tendering option holders, by execution of this letter,
waive any right to receive any notice of the acceptance of their tender, except

determined by Radyne ComStream in its discretion, which determinations will be
final and binding on all parties. Radyne ComStream reserves the right to reject
any or all tenders of options Radyne ComStream determines not to be in proper

the conditions of the Offer and any defect or irregularity in the tender of any
particular options, and Radyne ComStream's interpretation of the terms of the

irregularities in connection with tenders must be cured within such time as
Radyne ComStream will determine. Neither Radyne ComStream nor any other person
is or will be obligated to give notice of any


                                       6
