adjusted as follows:

                        (i) It shall be increased by the amount that the Closing

"Target Net Assets"); or

                        (ii) it shall be decreased by the amount that the

                        (iii) The Target Net Assets shall be the net book value
of the Company as reflected on the Balance Sheet less the amount of liabilities
shown on Schedule 2.3.

                        (iv) The "Closing Date Net Assets" shall be the net book
value of the Company as reflected on the Closing Date Balance Sheet less the
amount of liabilities shown on Schedule 2.3 as adjusted to reflect the changes
therein occurring between April 24, 1998 and the Closing ("Adjusted Schedule
2.3").

                        (v) The Closing Date Balance Sheet shall be prepared in
accordance with GAAP, except that the Closing Date Balance Sheet accounts
receivable and inventory reserves shall be determined in a manner consistent
with that used in determining the accounts receivable and inventory reserves

interest in effect on the Closing Date as stated in the "Money Rates" section of

                  (b) Preparation of Closing Date Balance Sheet and Adjusted
Schedule 2.3. As soon as practicable, and in any event within thirty (30) days
after the Closing Date, Seller shall cause the balance sheet for the Company as
of the close of business on the Closing Date (the "Closing Date Balance Sheet")
to be prepared in accordance with GAAP, except that the Closing Date Balance
Sheet accounts receivable and inventory reserves shall be determined in a manner
consistent with that used in determining the accounts receivable and inventory
reserves reflected on the Balance Sheet. Also, as soon as practicable, and in
any event within 30 days after the Closing, Seller shall cause the Adjusted
Schedule 2.3 to be prepared on a basis consistent with Schedule 2.3. The
Adjusted Schedule 2.3 and Closing Date Balance Sheet shall be accompanied by a
certificate of Seller's Chief Financial Officer stating that the same present
fairly, in all material respects, the financial condition of the Business as of
the Closing Date. Buyer shall provide Seller and Neutral Auditor such access to
the books and records as may reasonably be required for the preparation and/or
review of the Adjusted Schedule 2.3 and Closing Date Balance Sheet.

                  (c) Review of Adjusted Schedule 2.3 and Closing Date Balance
Sheet. After receipt of the Adjusted Schedule 2.3 and Closing Date Balance
Sheet, Buyer shall have thirty (30) days to review it. Buyer and its authorized
representatives shall have full access to all books and records and appropriate
employees of the Seller and the Company and its accountants to the extent
required to complete their review of the Adjusted Schedule 2.3 and Closing Date
Balance Sheet, including work papers used in preparation thereof. Unless the
Buyer delivers written notice to Seller on or prior to the 45th day after
receipt of the Adjusted Schedule 2.3 and Closing Date Balance Sheet specifying
in reasonable detail all disputed items and the basis therefor, the parties
shall be deemed to have accepted and agreed to the Adjusted Schedule 2.3 and
Closing Date Balance Sheet. If Buyer so notifies the Seller of an objection to
the Adjusted Schedule 2.3 and/or the Closing Date Balance Sheet, the parties
shall, within thirty (30) days following the date of such notice (the
"Resolution Period"), attempt to resolve their differences in good faith and any
resolution by them as to any disputed amount shall be set forth in a written
statement signed by each of Seller and Buyer and shall be final, binding,
conclusive and nonappealable for all purposes under this Agreement.

                  (d) Resolution. If at the conclusion of the Resolution Period
the parties have not reached an agreement on the objections, then all amounts
remaining in dispute may, at the election of either party, be submitted to Price
Waterhouse or another large international accounting firm not otherwise engaged
by either party that is mutually acceptable to Buyer and Seller (the "Neutral
Auditor"). Each party agrees to execute, if requested by the Neutral Auditor, a
reasonable engagement letter. All fees and expenses relating to the


                                       -8-

<PAGE>   15



work, if any, to be performed by the Neutral Auditor shall be borne equally by
Seller and Buyer, unless the Neutral Auditor finds one party acted in bad faith
in which case that party pays all. Except as provided in the preceding sentence,
all other costs and expenses incurred by the parties in connection with
resolving any dispute hereunder before the Neutral Auditor shall be borne by the
party incurring such cost and expense. The Neutral Auditor shall act as an
arbitrator to determine, based solely on the presentations by Seller and Buyer,
and not by independent review, only those issues still in dispute and such
determination shall be within the range of positions taken by Seller and Buyer
with respect to the applicable disputed item. The Neutral Auditor's
determination shall be made within thirty (30) days of its engagement (which
engagement shall be made no later than five (5) business days after election by
either party to submit the objections to the Neutral Auditor) or as soon
thereafter as possible, shall be set forth in a written statement delivered to
Seller and Buyer and shall be final, binding, conclusive and nonappealable for
all purposes hereunder.

            2.7 Due To/From Parent. As of the date of the Balance Sheet, the
Company opened Due to Parent and Due from Parent Accounts, each of which shows a
zero balance on the Balance Sheet. At the time of payment of the purchase price
adjustment pursuant to Section 2.6 hereof, Buyer shall remit to Seller the
amount by which the Due to Parent Account exceeds the Due from Parent Account or
Seller shall remit to Buyer the amount by which the Due from Parent Account
exceeds the Due to Parent Account, as the case may be, in each case together
with interest from the Closing Date at the Prime Rate on the amount payable.

            2.8 The Closing. The Closing shall take place at the offices of

            2.9 Deliveries. At the Closing, Seller shall deliver to Buyer (a)
such assignments and other good and sufficient instruments of transfer as shall
be satisfactory in form and substance to Buyer, and shall be effective to vest
in Buyer good and marketable title, free and clear of any liens and encumbrances
or rights and claims of others, to all of the outstanding stock of the Company,
(b) all of the Company's minute books and stock books, and (c) such resignations

their date of employment by Buyer, be eligible to participate in the medical,

to create any third-party beneficiary rights.

representation or warranty of the Seller and the Company contained in the
Agreement, or in any statement or certificate furnished Buyer pursuant to the

                                 Indemnification

            6.1 Indemnity to the Seller. Subject to the provisions of Section

other limitations contained herein, from and after the Closing, Buyer agrees to
indemnify, defend and hold harmless the Seller and each of its Affiliates,

breach of any representation or warranty made by Buyer in this Agreement or in
any written statement, certificate or schedule furnished by Buyer pursuant to

            6.2 Indemnity to Buyer. Subject to the provisions of Section 6.5
hereof relating to the survival of representations and warranties and the other
limitations contained herein, from and after the Closing, the Seller agrees to
indemnify, defend and hold harmless Buyer and the Company and their Affiliates,
officers, directors, employees, agents and shareholders (collectively, the
"Buyer Indemnitees") against all Losses incurred by any of the Buyer Indemnitees
and arising out of or relating to: (i) all Excluded Liabilities (with the
exception that as to any Environmental Liability, this indemnity shall extend
only to any Environmental Liability directly allocable to Seller's or the
Company's occupancy of or operations on the Property prior to the Closing); (ii)
any misrepresentation or breach of any representation or warranty made by the
Seller in this Agreement or in any written statement, certificate or schedule
furnished by the Seller pursuant to the provisions of this Agreement; and (iii)
any breach of any covenant, agreement or obligation of the Seller contained in
this Agreement or any other agreement, instrument or document executed by Seller
in connection with this Agreement. Notwithstanding the foregoing, damages based
on a breach of representation or warranty shall constitute Losses for the
purpose of this Section 6.2 only to the extent of the direct damages incurred
(excluding consequential damages, whether or not foreseeable).

            Seller shall not be required to indemnify Buyer Indemnitees with
respect to any claim for indemnification resulting from or arising out of
matters described above pursuant to this Section, other than for any breach of
the representations contained in the first two sentences of Section 3.1, Section
3.2, Section 3.4 and Section 3.20 or any Environmental Liability for which
Seller is responsible hereunder or Seller's Employee Liabilities, unless and
until the aggregate amount of all claims against Buyer Indemnitees exceeds

Claims thereafter may be asserted regardless of amount. Other than for any
breach of the representations contained in the first two sentences of Section

Environmental Liability for which Seller is responsible hereunder, Seller's
maximum liability to Buyer Indemnitees under this Section shall not exceed

            6.3   Third Party Claims.

                  (a) The Buyer, on behalf of any Buyer Indemnitee wishing to
claim indemnification under Section 6.2, and the Seller, on behalf of any Seller
Indemnitee wishing to claim indemnification under Section 6.1, upon learning of
any claim, action, suit, proceeding and/or investigation as to which such Buyer
Indemnitee or Seller Indemnitee may be entitled to be indemnified pursuant to
Section 6 of this Agreement (as applicable, an "Indemnified


                                      -23-

<PAGE>   30

Party"), shall notify the other party (the "Indemnifying Party") pursuant to
this Section 6 in writing; provided, however, that no failure so to notify the
Indemnifying Party shall relieve the Indemnifying Party of any obligation to
indemnify the Indemnified Party unless and to the extent such failure so to
notify prejudices the position of the Indemnifying Party in responding to such
claim, action, suit and/or proceeding.

                  (b) If the facts giving rise to any indemnification provided
for in this Section 6 involve any actual and/or threatened claim and/or demand
by any person other than the Indemnified Party, the Indemnified Party shall
tender to the Indemnifying Party the defense or prosecution of such claim and
any litigation resulting therefrom. The Indemnifying Party shall be entitled to
assume the defense of such claim. The Indemnifying Party shall then take all
steps reasonably necessary in the defense, prosecution or settlement of such
claim or litigation and will hold the Indemnified Party harmless from and
against all Losses caused by and/or arising out of any settlement thereof
approved by the Indemnified Party (which approval shall not be unreasonably
withheld or delayed) or any judgment in connection therewith (other than the
Indemnified Party's expenses of participation in such defense, prosecution
and/or settlement). If the defense or prosecution of a third party claim is
assumed by the Indemnifying Party, the Indemnified Party shall be entitled, at
its own expense, to participate in such settlement or defense through counsel
chosen by the Indemnified Party. If the Indemnifying Party does not assume the
defense of any such claim or legal proceeding resulting therefrom within 30 days
after the date of receipt of the notice referred to in Subsection 6.4 below (or,
if earlier, by the tenth day preceding the day on which an answer or other
pleading must be served in order to prevent judgment by default in favor of the
person asserting such claim), (a) the Indemnified Party may defend against such
claim or legal proceeding, in such manner as it may deem appropriate, including,
but not limited to, settling such claim or legal proceeding, after giving notice
of the same to the Indemnifying Party, on such terms as the Indemnified Party
may deem appropriate, and (b) the Indemnifying Party shall be entitled to
participate in (but not control) the defense of such action, with its counsel
and at its own expense. In the event that the Indemnifying Party proposes a
settlement to any such claim or legal proceeding, which settlement is
satisfactory to the party instituting such claim or legal proceeding and
includes (i) an unconditional release of the Indemnified Party from all
liability with respect to such claim or litigation or the dismissal of such
claim or litigation against the Indemnified Party with prejudice and (ii)
provision that all damages and settlement payments are to be made by the
Indemnifying Party and the Indemnified Party withholds its consent to such
settlement, then in any such case the Indemnifying Party shall have no
obligation to indemnify the Indemnified Party under this Section against and in
respect of the amount


                                      -24-

<PAGE>   31

by which the damages resulting from a final judgment relating to such claim or
legal proceeding exceeds the amount of the proposed settlement.

            6.4   Procedures for Asserting Claims.

                  (a) The Indemnified Party shall give written notice to the
Indemnifying Party of any claim for Losses for which the Indemnified Party
claims a right of indemnification under this Section 6 (a "Claim Notice"). If
known to the Indemnified Party, any such Claim Notice shall include (i) a
summary description of the facts upon which such claim is based and shall
specify the estimated amount of the Loss thereof and (ii) the amount which is
payable to the Indemnified Party pursuant to this Section 6.

                  (b) The Indemnifying Party shall have 30 days (or such shorter
time as may be required to avoid materially prejudicing the Indemnified Party's
position) following delivery of the Claim Notice to make such investigation of
the claim as it deems necessary or desirable. In connection with the
Indemnifying Party's evaluation of any Claim Notice, the Indemnified Party
shall, at the Indemnifying Party's expense, provide the Indemnifying Party with
reasonable access to the books and records of the Indemnified Party and, subject
to the implementation of reasonable procedures to protect the confidentiality of
such information, supply such factual and technical information as the
Indemnifying Party may reasonably require in connection with the evaluation of
such Claim Notice. On or prior to the expiration of such 30-day (or shorter)
period, the Indemnifying Party shall, by written notice to the Indemnified Party
(a "Response Notice"), either (i) admit liability in whole, or (ii) admit that
the claim is so covered by this Section 6 but dispute the amount of the claim,
or (iii) dispute that any amount of the claim is so covered. If the Indemnifying
Party fails to deliver a timely Response Notice to the Indemnified Party with
respect to a specified claim for indemnification, then the Indemnifying Party
shall have been deemed to admit liability in whole with respect to such
Indemnified Party's claim for indemnification.

                  (c) If the Indemnifying Party delivers to the Indemnified
Party a timely Response Notice pursuant to Section 6.4(b) disputing the amount
of the claim or disputing that the claim is covered by this Section 6 or if any
other dispute arises with respect to this Agreement, then the Indemnifying Party
and the Indemnified Party shall use their commercially reasonable best efforts
to resolve such dispute. In the event the Indemnifying Party and the Indemnified
Party resolve the dispute, they shall both execute a memorandum setting forth
such resolution and, if applicable, the amount payable by the Indemnifying Party
to the Indemnified Party. In the event the Indemnifying Party and the
Indemnified Party are unable to resolve such


                                      -25-

<PAGE>   32

dispute within 30 days from the Indemnified Party's receipt of the Response
Notice pursuant to Section 6.4(b), the Indemnifying Party and the Indemnified
Party shall determine whether they can agree upon a third-party impartial
arbitrator (the "Arbitrator") to whom to submit the matter in dispute for final
and binding arbitration pursuant to Title 9 of the California Code of Civil
Procedure (Section 1280, et seq.) (the "California Arbitration Law").

            If the Indemnifying Party and the Indemnified Party fail to agree on
the Arbitrator within 10 days, each party shall select an Arbitrator who shall
be a member of the American Arbitration Association (the "AAA"). If one party
does not so select such an Arbitrator within the time specified, then the issue
shall be resolved solely by the Arbitrator chosen by the other party in
accordance with the foregoing procedure. If each party does select such an
Arbitrator as provided herein, then within five (5) days of the appointment of
the second of the two Arbitrators, the two Arbitrators shall select a third
Arbitrator. If the two original Arbitrators are unable to agree upon the
selection of a third Arbitrator, then either party may request that the San
Francisco AAA appoint a third Arbitrator. All Arbitrators selected for
arbitration hereunder shall be members of the AAA, shall not be affiliated with
any of the parties and shall have expertise in the subject matter which is the
basis of the dispute. In the event AAA is no longer in business and/or will not
perform such service at the time of the disputes, the Arbitrator shall be
selected by a judicial court of competent jurisdiction.

            The Arbitrator(s) and the Indemnifying Party and the Indemnified
Party shall meet within ten days of the election of the Arbitrator(s) for a
preliminary conference regarding procedures to be followed in connection with
the arbitration. Within thirty (30) days thereafter, the parties shall meet in
San Jose, California, with such Arbitrator(s) at a place and time designated by
the Arbitrator(s) after consultation with the parties and present their
respective positions on the dispute. Each party shall have no longer than eight
hours to present is position, the entire proceeding before the arbitrator shall
be on no more than three consecutive days, and the award shall be made in
writing no more than 30 days following the end of the proceeding. Such award
shall be a final and binding determination of the dispute and shall be fully
enforceable as an arbitration award in accordance with the California
Arbitration law. The Arbitrator(s) shall have discretion to award attorneys'
fees and expenses in connection with such proceeding. Each party shall bear
one-half of the Arbitrator(s)' fees and expenses.

            6.5 Expiration of Representations and Warranties, etc. All
representations and warranties contained in this Agreement shall survive the
Closing for a period of 24 months; provided that the representations and
warranties stated in Section 3.2, Section 3.4 and Section 4.2 shall survive


                                      -26-

limitations.

            6.6 Exclusive Remedy. The indemnifications provided for in this
Section 6 shall be the sole and exclusive post-Closing remedies available to
either party against the other party for any claims under or based upon this
Agreement.

            The obligations of the Seller to consummate the transactions

                                    SECTION 9

                                Certain Covenants

            9.1 Operation of Business Prior to Closing. The Business shall be
operated by Seller and the Company in the ordinary course in substantially the
same manner as heretofore conducted from the date hereof to the Closing. The
Business shall be operated by the Seller and the Company in a manner that will
not cause any of the Seller's and the Company's representations and warranties
set forth in Section 3.19 to be untrue when taken or at the Closing Date. From
the date hereof until Closing, Seller and the Company agree to pay the
liabilities reflected on Schedule 2.3 and liabilities incurred in the ordinary
course of the Business of the Company in accordance with past practices.

            9.2 Communications with Customers and Suppliers. The Seller and
Buyer will mutually agree upon all communications with suppliers and customers
relating to this Agreement and the transactions contemplated hereunder prior to
the Closing Date.

            9.3 Non-Competition. For three years following the Closing, neither
Seller nor any of its Affiliates shall engage or be interested, directly or
indirectly (except as a holder of not more than five percent of the combined
voting power of the outstanding stock of a publicly held company), (a) in
manufacturing or selling the products currently being manufactured or sold by
the Business, or (b) in providing the satellite services currently being
provided by the Business, except that this provision shall not preclude (i)
Seller or any of its Affiliates from being acquired by any person or entity that
provides such products or services or restrict the activities of any such person
or entity after the acquisition (provided that such acquisition is not merely in
connection with a reincorporation or similar reorganization of Seller), or (ii)
Seller or any of its


                                      -30-

<PAGE>   37

Affiliates from manufacturing or selling any of the products that the Seller or
any of its Affiliates (other than the Company) currently manufactures or sells.

            Inasmuch as the remedy at law for any breach by Seller of the
covenant contained in this Section 9.3 is inadequate, the Buyer shall be
entitled to injunctive relief to enforce the same.

            9.4 Novations. Seller agrees to use its commercially reasonable
efforts to obtain any novation required in connection with any of the Contracts
listed on Schedule 3.13(c) within 90 days of the Closing Date and agrees pending
the obtaining of such novations to take all commercially reasonable action
necessary to assure the receipt by Buyer of all benefits accruing under those
Contracts from and after Closing.

            9.5   Use of Business Names by Buyer.

                   (i) Concurrently with the Closing, Buyer agrees to amend the
Certificate of Incorporation of the Company to change the name of the Company to
a name that does not include "California Microwave."

                  (ii) Buyer acknowledges that Seller has the absolute and
exclusive proprietary right to all names, marks, trade names, trademarks,
service names and service marks (collectively, "Names") incorporating
"California Microwave" or any similar Name and to all corporate symbols or logos
(collectively, "Logos") incorporating California Microwave or any similar name.
All rights of Seller and its Affiliates to the same and the goodwill represented
thereby and pertaining thereto are being retained by Seller. Buyer agrees that
it will not, and will cause the Business not to, use the California Microwave
Name or any similar Name or any Logo incorporating such Name or any similar Name
in any manner, including in connection with the sale of any products or services
or otherwise in the conduct of the Business, except as expressly permitted by
clause (iii) of this Section 9.5.

                  (iii) For a period of nine (9) months from the Closing Date
(the "Window Period"), Seller shall and hereby irrevocably grants, effective as
of the Closing Date, on a fully-paid, royalty-free basis, the Buyer the right to
use the California Microwave Logo and the California Microwave Name in
connection with the operation of the Business as currently conducted including,
during the Window Period, to (A) use any molds or castings included in the
equipment or machinery included in the Assets despite the appearance thereon and
on the products manufactured therewith of the California Microwave Name or the
California Microwave Logo, (B) market and sell all such products produced by the
Business and (C) use any other assets on hand included in the Acquired Assets,
including, without limitation, any


                                      -31-

<PAGE>   38

catalogs, invoices, packaging material or stationery, bearing the California
Microwave Name or California Microwave Logo (provided, however, that Buyer shall
use its commercially reasonable efforts to cease its use of the California
Microwave Name and the California Microwave Logo within six (6) months).
Immediately upon the expiration of the Window Period, Buyer shall cease to use
in any manner the California Microwave Name or the California Microwave Logo
incorporating such Name and remove or obliterate such Name or the California
Microwave Logo from any molds, castings, products or other assets and clearly
and prominently mark the new name of the Business thereon. At all times
following the Closing, Buyer shall not indicate that Buyer or the Business is
affiliated with Seller or any of its affiliates.

            9.6   Consents; Cooperation.  Seller, the Company and Buyer will
use their commercially reasonable efforts:

                  (a) to obtain prior to the earlier of the date required (if so
required) or the Closing Date, all authorizations, consents, orders, permits or
approvals of, or notices to, or filings, registrations or qualifications with,
all governmental authorities or any other person or entity that are required on
their respective parts, for the consummation of the transactions contemplated by
this Agreement;

                  (b) to defend, consistent with applicable principles and
requirements of law, any lawsuit or other legal proceeding, whether judicial or
administrative, whether brought derivatively or on behalf of third persons
(including governmental authorities) challenging this Agreement or the
transactions contemplated hereby;

                  (c) to furnish to each other such information and assistance
as may reasonably be requested in connection with the foregoing; and

                  (d) to (i) take, or cause to be taken, all action and to do,
or cause to be done, all things necessary, proper or advisable to consummate and
make effective the transactions contemplated by this Agreement (excluding
satisfying the closing conditions in Section 7 or 8 hereof insofar as they
relate to the truth of representations and warranties but including otherwise
satisfying the closing conditions in Sections 7 and 8) and (ii) refrain from
taking any action which reasonably could be expected to render any
representation or warranty contained in this Agreement untrue or incorrect in
any material respect (except to the extent a representation or warranty or
covenant is qualified by materiality in which case the Seller will refrain from
taking any action that would render such representation or warranty untrue or
incorrect) as of Closing.

<PAGE>   39

            9.7 Notice of Developments. The Seller and the Company will give
prompt notice to the Buyer of any fact, to the Seller's and Company's knowledge,
that would, if it were true on the Closing Date, constitute a breach of the
Seller's and the Company's representations and warranties in this Agreement.
Each party to this Agreement will give prompt written notice to the other of any
material development affecting the ability of such party to consummate the
transactions contemplated by this Agreement. No disclosure by any party to this
Agreement pursuant to this Section 9.7, however, shall be deemed to amend or
supplement any Schedule to this Agreement or to prevent or cure any
misrepresentation, breach of representation or warranty, or breach of covenant.

            9.8   Non-Solicitation.

                  (a) The Seller agrees that for a period of three (3) years
from the Closing Date neither the Seller, nor any direct or indirect subsidiary
of Seller shall, for themselves or for any other person or entity, directly
solicit, hire or take away or directly attempt to solicit, hire or take away any
of E. Russell Hardy, Stephen Strohman, Monty J. Moore, Salvador Giblas, Don
Hoshi, Robert Lopez and James Dale (collectively, the "Key Transferred
Employees").

                  (b) The Seller agrees that for a period of three (3) years
from the Closing Date neither the Seller nor any direct or indirect subsidiary
of Seller shall, for themselves or for any other person or entity directly
solicit or directly attempt to solicit any employee of the Company who is not a
Key Transferred Employee and for a period of nine (9) months neither the Seller
nor any direct or indirect subsidiary of Seller shall, for themselves or for any
other person or entity, directly hire any employee of the Company who is not a
Key Transferred Employee.

and its representatives full access to the premises, property, files, books,
records, documents, and other information concerning the Business, (b) furnish
to Buyer and its representatives financial, technical, legal and operating data
and other information pertaining to the Business, (c) make available for
inspection and copying by Buyer copies of any documents relating to the
foregoing and (d) permit Buyer and its representatives to conduct reasonable
interviews of the employees, representatives and auditors of Seller concerning
the Business; provided, however, that any such investigation will be conducted
in such a manner as not to interfere unreasonably with the operation of the
Business. During the period from the date hereof to the Closing, all information
provided to Buyer or its representatives by or on


                                      -33-

<PAGE>   40

behalf of Seller or its representatives will be maintained by Buyer in the
strictest confidence. From and after the Closing Date, the Seller will maintain
any information retained by it (whether pursuant to the terms of this Agreement
or otherwise) that relates to the Business in the strictest confidence.

            9.10 Cooperation with Respect to Borregas Avenue Lease. From and
after the Closing Date, Buyer and Seller shall use their commercially reasonable
efforts to obtain consent to the assignment to the Company of the Borregas
facility lease. In the event such assignment occurs, the Company will sublease
to Seller approximately 12,000 square feet on substantially the same terms as
set forth in Exhibit D.

                  (d) by either Buyer or Seller and the Company if the Closing

                                      -34-

<PAGE>   41

Agreement shall be effected by written notice signed by the party or parties
having the right to terminate this Agreement in accordance with Section 10.1

relating to announcements, and except that such termination shall not relieve
any party then in breach of any representation, warranty, covenant or agreement

                                SUPPLY AGREEMENT


        THIS SUPPLY AGREEMENT (this "Agreement") is dated _____ ___, 1998 and is
entered into between California Microwave, Inc., a Delaware corporation
("Seller"), and California Microwave Services Division, Inc., a
Delaware corporation ("Buyer").

                                    RECITALS

        A. Seller, Buyer and Telscape International, Inc. have entered into an
stock purchase agreement dated as of ________ __, 1998, as amended (the
"Purchase Agreement"), with respect to the acquisition by Telscape
International, Inc. from Seller of all of the outstanding capital stock of
Buyer.

        B. The business of Buyer is comprised of (i) the satellite hub
operations located in Mountain View, California, which provide, via leased (to
its customers) satellite communications links, data broadcast and interactive
communication services and (ii) the products operation in Sunnyvale, California,
which manufactures and sells the Equatorial, radar test equipment, frequency
converter, frequency source, amplifier and Radiolink product lines and the
warranty sales and depot services relating to those product lines (collectively,
such businesses are the "Business").

        C. On and after the date hereof (the "Closing Date"), Seller and Buyer
desire to continue certain arrangements pursuant to which Seller supplies
certain products to Buyer.

        NOW THEREFORE, as a condition to the closing of the transactions
contemplated by the Purchase Agreement, and in consideration of the mutual
covenants, representations and warranties made herein, and of the mutual
benefits to be derived hereby, the parties hereto agree as follows:

        1. Supply of Products by Seller. Upon the terms and subject to the
conditions hereof, for three years from the Closing Date, Seller shall sell to
Buyer, and Buyer shall purchase from Seller, all of the Business's requirements
of the products listed on EXHIBIT A and any extensions and improvements of those
products (the "Products"). Without limiting the obligation of Buyer to purchase
its requirements of Products under the preceding sentence, the quantities of
Products to be purchased by Buyer pursuant to this Section shall be at the sole
discretion of Buyer and no minimum quantities of Products are required to be
purchased hereunder. Notwithstanding the preceding two sentences, if Seller
provides written notice to Buyer specifying any Products subject to this Section
that Seller intends to discontinue providing to its customers, Seller will be
relieved of any obligation to sell to Buyer, and Buyer will be relieved of any
obligation to buy from Seller, any such Products as of six months from the date
that Seller so notifies Buyer. Exhibit A may be

                                       -1-

<PAGE>   49

amended to add or delete products therefrom or for any other purpose by written
agreement of Buyer and Seller.

        2. Prices. Seller shall sell the Products at prices no less favorable
than the prices given to other Customers of such products in like quantities,
except that in no event shall such prices be greater for a given Product than
(i) those prices listed opposite such Products' name on EXHIBIT A attached
hereto and (ii) the lowest price provided by Seller to Buyer for any such
Product during the six calendar months preceding the date of the most recent
purchase order of Buyer so long as, in the case of item (ii), Buyer has
purchased at least $_______ of Products from Seller during such six month
period.

               As used in this Agreement, "Customer" shall mean any end user,
reseller, agent, government entity or distributor.

        3. Additional Terms and Conditions. Any sale of the Products by Seller
under this Agreement shall be subject to and governed by the then-current
standard terms and conditions (including as to warranty) of Seller, which terms
and conditions shall be no less favorable than those given to other Customers
for the same or similar Products in like quantities.

        4. Specifications. Seller shall manufacture and deliver the Products in
accordance with the electrical, mechanical, physical, environmental and other
specifications as in effect as of the Closing Date, or if the Product is
non-standard, then according to the specifications agreed to in writing by Buyer
and Seller from time to time. In the event an improvement or a technical change
in the specifications of the Products is made by the Seller, then it shall be
required to provide Products that meet such improved or changed specifications.

        5. Maintenance of Standards. If Seller fails to maintain the quality,
delivery or performance standards currently applicable to the Products, or fails
to achieve standards of quality or performance specified by Buyer with respect
to new variations of standard Products, then Buyer shall have such remedies as
may be provided in the then-current standard terms and conditions of Seller, and
if Seller fails to cure any such deficiency in any Product to be sold by it
hereunder within sixty (60) days after written notice thereof by Buyer, Buyer
shall no longer be obligated to purchase such Product pursuant to this
Agreement.

        6. Ordering. Each order by Buyer for Products of Seller (a "Purchase
Order") will specify each Product being purchased, the quantity, any appropriate
specifications corresponding to each such Product, and the date of delivery,
provided that the number of days from the date of the Purchase Order through the
date of delivery is at least sixty (60) days. Notwithstanding the foregoing, the
parties hereafter may agree in writing to use a blanket purchase agreement with
specific agreed call out schedules in lieu of the foregoing ordering mechanism.

        7.     Delivery.

               (a) All Products sold hereunder will be delivered freight paid
FOB (Seller's plant).

               (b) Buyer reserves the right to inspect the Products sold by
Seller and to confirm the quantity of the Products within thirty (30) days from
the date of delivery. Any claims for discrepant deliveries shall be reported by
Buyer to Seller in writing within such 30-day period. If Buyer fails to make
such a claim within the time specified, such order will be deemed accepted by
Buyer. Upon Seller receiving notice from Buyer of such discrepancy, Buyer will
have such remedies as may be provided in the then-current standard terms and
conditions of Seller.

               (c) Seller will keep Buyer promptly and regularly informed of
difficulties that Seller expects in meeting Buyer's needs for delivery in
accordance with lead time(s) stated in any Purchase Order.

        8. Raw and Packaging Materials. Seller will purchase and supply all raw
materials and packaging materials necessary for the manufacture of the Products
sold by it hereunder. Seller will be responsible for the sampling and testing of
all such raw materials and packaging materials and for ensuring an adequate
inventory of such raw materials and packaging materials to supply the Products
sold by it hereunder within the delivery time provided for in Section 6.

        9. Terms of Sale. With respect to any Products sold hereunder, Seller
will invoice Buyer at the time of delivery. Each invoice will be itemized in
reasonable detail. Buyer will pay to Seller the undisputed amount of such
invoice within 30 days of the date of delivery of the Product.

        10. Confidentiality. Each party will preserve the confidentiality of the
other party's Confidential Information (defined below), will not use same except
in connection with the performance of its obligations hereunder, and will return
same upon request by the other party. This Section will survive expiration or
earlier termination of this Agreement for a period of three years thereafter.
"Confidential Information" means all proprietary information (including but not
limited to formulas, compilations, data, know-how, specifications, techniques,
inventions, devices, projections, drawings and plans, whether of a technical,
operational, financial or other nature) which hereafter is, or in the past has
been, disclosed in writing and marked as confidential by either party (the
"Disclosing Party") to the other party (the "Receiving Party"), and which is of
such a nature that its value would be impaired if disclosed to third parties,
but shall not include any such information that: (i) becomes part of the public
domain through no fault of the Receiving Party; (ii) at the time of receipt is
known to the Receiving Party as shown by its written records; (iii) becomes
known to the Receiving Party from another source and the Receiving Party is not
aware that such source is under an obligation to another person or entity to
keep such information

                                       -3-

<PAGE>   51

confidential; (iv) is required to be disclosed by the Receiving Party as a
result of judicial or administrative process or by other requirements of law; or
(v) was independently developed by the Receiving Party, without reference to the
Confidential Information, provided such independent development can be
reasonably supported by the Receiving Party's written records.

        11. Term. This Agreement shall commence on the date first set forth
above and shall expire on the third anniversary of the Closing Date unless
earlier terminated pursuant to Section 12.

        12. Termination.

               (a) Either party may terminate this Agreement for any material
breach of this Agreement by the other party if the party seeking to terminate
has specified such breach in writing and such breach has not been cured by the
breaching party within thirty (30) days after receipt of the written notice.

               (b) Termination under this Section will be effected by notice
given by the terminating party to the other party.

               (c) Any termination of this Agreement will not affect any of the
rights of either party hereto that arose prior to such termination or any
liability resulting from either party's breach of this Agreement.

        13. Consequences of Termination. Upon expiration or earlier termination
of this Agreement, each party will promptly return to the other all documents,
samples and other tangible items containing or representing Confidential
Information and all copies thereof, and certify, if requested by the other
party, that it has complied with the terms of this sentence. This Section will
survive expiration or earlier termination of this Agreement.

        14. Sales Convey No Right to Manufacture or Copy. The Products offered
for sale hereunder are offered for sale and are sold by each party subject in
every case to the condition that such sale does not convey any license,
expressly or by implication, to manufacture, duplicate or otherwise copy or
reproduce any of the Products, unless expressly provided in such sale.

        15. Export Control Compliance. Buyer agrees to comply fully with the
United States Export Control Administration Regulations, the United States
Department of State International Traffic in Arms Regulations and any other
United States government regulations applicable to the export or disclosure of
Products provided hereunder or Confidential Information hereunder insofar as
they may control or limit the sale or use of Products. Buyer also agrees to
comply fully with the United States Foreign Corrupt Practices Act.

        16. Force Majeure. Except for Buyer's payment obligations to Seller for
the Products previously delivered or provided hereunder, failure of either party
to perform its obligations under this Agreement (including but not limited to
failure to make sales or deliveries of the Products) shall be excused

                                       -4-

<PAGE>   52

to the extent that such failure is attributable to any cause beyond the
reasonable control of the defaulting party, including, without limitation, acts
of God, fires, earthquakes, wars, sabotage, accidents, embargo, riots, labor
disputes, actions of any government or governmental agency or failure of same to
act where action is required, and the inability of such party to obtain material
from its suppliers or to obtain equipment or transportation; and the time during
which such party may perform will be extended to coincide with the time
performance has been prevented, hindered or delayed as a result of the
foregoing. Should either party wish to claim relief from its obligations
hereunder by reason of this Section, such party shall give notice to the other
party without delay of the occurrence of the event or circumstances in question.

        17. Governing Law. This Agreement shall be governed in all respects,
including, without limitation, as to validity, interpretation and effect, by the
internal laws of the State of California, without giving effect to the conflict
of laws rules thereof. The parties hereby agree that this Agreement shall not be
governed by the United Nations Convention on Contracts for the International
Sale of Goods.

        18. Assignment. The Agreement shall not be assignable or otherwise
transferable by either party hereto without the prior written consent of the
other party, which consent will not be unreasonably withheld. This Agreement
will bind and inure to the benefit of the successors and permitted assigns of
the parties hereto. References to a party herein also are deemed to be
references to any successor or permitted assign of such party.

        19. Notices. All notices, consents, approvals, requests, demands,
waivers and other communications required or permitted to be given under this
Agreement shall be in writing and shall be deemed to have been duly given if:

                                    SUBLEASE


               THIS SUBLEASE (this "Sublease") is entered into as of the ___ day
of _________, 1998, by and between (i) CALIFORNIA MICROWAVE, INC., a Delaware
corporation ("Sublessor"), and (ii) CALIFORNIA MICROWAVE SERVICES DIVISION,
INC., a Delaware corporation ("Sublessee").

        A. Sublessor previously entered into that certain Lease dated May 8,
1995, as amended by that certain First Amendment to Lease dated June 7, 1995
(collectively, the "Master Lease"), by and between Sublessor, as tenant, and
RREEF USA Fund-II, Inc. ("RREEF"), as landlord, pursuant to which Sublessor is
leasing approximately 41,472 rentable square feet of office and industrial space
located at 1143 Borregas Avenue, Sunnyvale, California, as more particularly
described in the Master Lease (the "Premises"). A copy of the Master Lease is
attached hereto as Exhibit I. The current landlord under the Lease is AMB
Property, L.P. (the "Master Landlord"), successor in interest to the AMB
Industrial Value Added Fund. Except as otherwise defined herein, all
initial-capitalized terms used herein shall have the same meaning as is ascribed
to such terms in the Master Lease.

        B. Sublessor has agreed to sublease to Sublessee a portion of the
Premises containing approximately 30,504 rentable square feet, as outlined in
the plan attached hereto as Exhibit II (such portion of the Premises being
hereinafter referred to as the "Subleased Premises"), and Sublessee desires to
sublet the Subleased Premises from Sublessor, on the terms, covenants and
conditions contained herein.

               NOW, THEREFORE, in consideration of the mutual covenants and
promises of the parties contained herein, the parties hereto agree as follows:

               1. SUBLEASE. Sublessor subleases to Sublessee and Sublessee hires
from Sublessor the Subleased Premises, in "AS IS" condition, subject to the
Master Lease. Notwithstanding the foregoing, Sublessor shall continue to have
the right to use in common with Sublessee the reception area, cafeteria, and
restrooms located in the Subleased Premises, and shall have the right to use the
Subleased Premises for ingress and egress to and from such areas and to the
portion of the Premises being retained by Sublessor.

<PAGE>   58

               2.     TERM.

                    (a) TERM. The term of this Sublease shall
commence on the date hereof (the "Commencement Date") and shall expire on July
31, 2000, subject to extension as provided in Section 2(b) below (the "Term").
Notwithstanding the foregoing, the Commencement Date shall not be deemed to have
occurred prior to the date that the parties have closed on that certain Stock
Purchase Agreement dated May ___, 1998, entered into between the parties and the
Landlord's Consent (as defined in Section 10 hereof) is obtained.

                      (b)    RENEWAL.  The parties acknowledge that
Article 39 of the Master lease provides for one (1) option (the "Master Lease
Option") to renew the Master Lease for a term of five (5) years (the "Option
Term"), from August 1, 2000 to July 31, 2005, at an Annual Rent of 95% of the
current fair market rental for comparable space in other similar buildings in
the same rental market as of the date the Option Term is to commence. Sublessor
shall exercise the Master Lease Option in accordance with the provisions of the
Master Lease, whereupon the Term shall be automatically extended for the length
of the Option Term. In the event of any arbitration to determine rent pursuant
to Article 39 of the Master Lease, the parties shall share the cost of such
arbitration in accordance with their respective percentages of the Premises
(including an equitable allocation of any areas of the Premises used in common
with Sublessor) at the time of the commencement of the Option Term.

               3.     RENT.

                      (a)    BASE RENT.  Commencing on the
Commencement Date, Sublessee shall pay to Sublessor during the Term as base rent
for the Subleased Premises the seventy-three and six-tenths percent (73.6%)
("Sublessee's Share") of the Annual Rent and Monthly Installment payable under
the Master Lease for the period of the Term. Sublessee's Share was computed by
dividing the rentable square footage of the Subleased Premises (i.e., 30,504) by
the rentable square footage of the Premises (i.e., 41,472). The amounts payable
pursuant to this Section 3(a) are hereinafter referred to as "Base Rent."
Payment for the first (1st) month of the Term shall be due on the Commencement
Date. Otherwise, monthly payments of Base Rent shall be due on or before the
first day of each month during the Term.

                      (b)    ADDITIONAL RENT.  As additional rent,
Sublessee shall pay Sublessor Sublessee's Share of Direct Expenses and Taxes
paid or incurred by Sublessor under Article 4 of the Master Lease at the same
time as such payments are due from Sublessor to Master Landlord under the


                                       -2-

<PAGE>   59

Master Lease, including any estimated payments payable pursuant to Section 4.4
of the Master Lease. Sublessor shall promptly provide Sublessee with estimates
or statements regarding increases in Direct Expenses and/or Taxes delivered by
Master Lessor to Sublessor under Section 4.4 of the Master Lease. Overpayments
and underpayments of Direct Expenses and Taxes shall be handled in the same
manner as provided under Section 4.5 of the Master Lease. Payments for the
calendar year 1998 shall be appropriately prorated.

                      (c)    SHARED COSTS.  The parties hereto
acknowledge that Sublessor may incur certain costs (of the nature shown on
Exhibit III attached hereto) with respect to the Premises which benefit both
itself and Sublessee, and Sublessee may incur certain costs (of the nature shown
on Exhibit III attached hereto) with respect to the Premises which benefit both
itself and Sublessor. Where Sublessor incurs costs which benefit Sublessee,
Sublessee shall reimburse Sublessor for its pro-rata share of those costs within
thirty (30) days of receipt of billing from Sublessor. Where Sublessee incurs
costs which benefit Sublessor, Sublessor shall reimburse Sublessee for its
pro-rata share of those costs within thirty (30) days of receipt of billing from
Sublessee. Exhibit III to this Sublease is a listing of costs which Sublessor
and/or Sublessee may incur which benefit the other party, the current estimated
monthly amount of such costs, and the allocation procedure to be used to
pro-rate the costs between the parties. The allocation procedure may be adjusted
by the mutual agreement of the parties. Costs incurred that are outside of the
categories listed on Exhibit III ("Additional Category Costs") must be agreed to
in advance in order for the paying party to seek reimbursement. The parties will
use their best efforts to agree on the most appropriate allocation procedure to
be used for Additional Category Costs and/or to reflect changing circumstances.
If the parties cannot agree, then such costs will be pro-rated as follows:

                             i)     One-half (1/2) of the cost based
                                    upon relative number of employees
                                    (including contract laborers)
                                    employed at the Premises; and

                             ii)    One-half (1/2) of the cost based upon
                                    relative rentable square footage leased at
                                    the Premises.

                      (d)    LATE PAYMENTS.  If any installment of
Base Rent or additional rent due from Sublessee under this Sublease shall not be
received by Sublessor within five (5) days of the date the same is due,
Sublessee shall pay to


                                       -3-

<PAGE>   60

Sublessor a late charge equal to six percent (6%) of such unpaid amounts.

                      (e)    PAYMENT.  Base Rent and additional rent
due hereunder shall be paid by Sublessee to Sublessor without deduction or
offset, and with respect to Base Rent, without demand.

               4.     USE.  Sublessee shall use the Subleased
Premises only for purposes allowed under the Master Lease and
for no other purpose.

               5.     MASTER LEASE.

                      (a) INCORPORATION FROM MASTER LEASE. Except as modified
herein, all of the terms and conditions contained in the Master Lease are
incorporated herein as terms and conditions of this Sublease, with each
reference therein to "Landlord" and "Tenant" deemed to mean Sublessor and
Sublessee, respectively, with each reference therein to the "Premises" deemed to
mean the Subleased Premises, and with each reference therein to "Term" deemed to
mean the Term (as defined in Section 2(a) hereof). Notwithstanding the
foregoing, the following sections, paragraphs or exhibits of the Master Lease
are excluded from this Sublease or are revised as indicated:

               Section 2.1; Section 2.2; Section 3.1; Section 3.2; Article 4
               (except as provided in Section 3(b) hereof); Section 5; Section
               7.5 shall be revised to provide that Sublessee shall be
               responsible for entering into the maintenance contract for all
               heating and air conditioning systems and equipment servicing the
               Premises, and that the parties shall share proportionately the
               cost thereof; Article 9; Section 11.2(a) shall be revised to
               provide that the insurance policies to be provided by Sublessee
               pursuant to Section 11.1 of the Master Lease shall name
               Sublessor, Master Landlord and the building management company,
               if any, as additional insureds; Article 22 (Sublessee recognizes
               that the Term of this Sublease shall terminate in the event of a
               termination pursuant to this Article; Sublessee shall be entitled
               to a proportionate amount of any abatement of rent Sublessor
               receives pursuant to Section 22.2); Article 24; Article 27;
               Article 32; Article 38; Article 40; Exhibit B; Addendum
               Paragraphs 1, 2, and clause (b) of Paragraph 3.

Nothing contained in this Section 5(a) is intended to alter the parties'
agreement as to certain shared costs set forth in Section 3(c) hereof.


                                       -4-

<PAGE>   61

                      (b) RECOURSE TO MASTER LANDLORD. Notwithstanding anything
contained in Section 5(a) above, it is understood and agreed that Sublessor
shall have no obligation or responsibility to provide or perform any service,
repair, restoration, alteration or other similar obligation which is the
obligation of Master Landlord to provide or perform pursuant to the provisions
and terms of the Master Lease including, but not limited to, the obligation of
Master Landlord to make restorations or repairs after damage to the Premises or
the Building by fire or other cause or after condemnation. Sublessee further
agrees that each such obligation shall be provided or performed by Master
Landlord and not by Sublessor. If Sublessee shall notify Sublessor that Master
Landlord is not supplying services to the Subleased Premises or performing other
obligations as required under the Master Lease, Sublessor will promptly request
Master Landlord to perform such services. Sublessor shall in no event be liable
to Sublessee nor shall Sublessee's obligations under this Sublease be impaired
or reduced or the performance thereof excused because of any failure or delay on
Master Landlord's part in providing any such services or in making any repairs
or alterations, or in performing or observing any similar obligation of Master
Landlord under the Master Lease. If Master Landlord shall default in its
obligation to provide services as required under the Master Lease to the
Subleased Premises, Sublessee shall be entitled to participate with Sublessor in
the enforcement of Sublessor's rights against Master Landlord, but Sublessor
shall have no obligation to bring any action or proceeding or otherwise act to
enforce Sublessor's rights against Master Landlord. If, after written request
from Sublessee, Sublessor shall fail or refuse, within a reasonable period of
time, to institute an action or proceeding for the enforcement of Sublessor's
rights against Master Landlord with respect to a failure to provide services
required to be provided to the Subleased Premises under the Master Lease,
Sublessee shall have the right to take such action in its own name, and for that
purpose and only to such extent, shall have the same rights as Sublessor under
the Master Lease. If any such action against Master Landlord in Sublessee's name
shall be barred by reason of lack of privity, nonassignability or otherwise,
Sublessee may take such action in Sublessor's name provided Sublessee has
obtained the prior written consent of Sublessor, which consent shall not be
unreasonably withheld; provided, however, that Sublessee shall indemnify and
hold Sublessor harmless from and against any and all liability, loss, claims,
demands, suits, penalties or damage (including, without being limited to,
reasonable attorneys' fees and expenses) which Sublessor may incur or suffer by
reason of such action. Sublessor shall provide Sublessee with a copy


                                       -5-

<PAGE>   62

of all notices delivered by Sublessor to the Master Landlord
pursuant to this Section 5(b).

                      (c) CONSENT OF MASTER LANDLORD. Whenever the provisions of
the Master Lease that have been incorporated as provisions of this Sublease
require the written consent of Master Landlord, said provisions shall be
construed to require the written consent of both Master Landlord and Sublessor.

                      (d) OBLIGATIONS RE MASTER LEASE. Sublessor agrees to
maintain the Master Lease in full force and effect, except to the extent any
failure to maintain the Master Lease is due to the failure of Sublessee to
comply with any of its obligations under this Sublease. During the Term,
Sublessor shall not enter into any amendment of the Master Lease that will
diminish Sublessee's rights or increase Sublessee's obligations hereunder.

               6. RESTORATION OBLIGATIONS. Notwithstanding anything to the
contrary contained herein, upon expiration or earlier termination of the Term,
Sublessee shall be responsible for all restoration and surrender obligations
under the Master Lease with respect to the Subleased Premises and Sublessor
shall be responsible for all restoration and surrender obligations under the
Master Lease with respect to the portion of the Premises being retained by
Sublessor.

               7. ASSIGNMENT AND SUBLETTING. Sublessee may not sublet the
Subleased Premises or assign this Sublease without the prior written consent of
Sublessor, which consent shall not be unreasonably withheld.

               8. SIGNAGE. Sublessor shall retain rights to its existing signage
at the Premises. Sublessee shall have the right to place signage on the exterior
of the Building, subject to the Master Landlord's consent and provided the same
does not interfere with Sublessor's signage.

               9.     MISCELLANEOUS.

                      (a) NOTICES. All notices or demands of any kind required
or desired to be given by Sublessor to Sublessee or Sublessee to Sublessor
hereunder shall be in writing and shall be sent by hand delivery or by a
nationally recognized courier service, in which event they shall be deemed given
when the same are received, or by depositing such notices or demands in the
United States mail, certified or registered, postage prepaid, return receipt
requested (unless return receipt indicates not delivered), in which event it
shall be deemed given seventy-two (72) hours after such deposit, or by facsimile
with receipt confirmed, in


                                       -6-

<PAGE>   63


which event it shall be deemed given upon such confirmation. All notices or
demands shall be addressed or faxed to Sublessor or Sublessee, as the case may
be, at the address or fax set forth after the signatures to this Sublease.

                      (b) ENTIRE AGREEMENT. This Sublease represents the entire
agreement between the parties to this Sublease and supersedes all prior
agreements between the parties, whether written or oral. There are no
representations between Sublessor and Sublessee other than those contained in
this Sublease. Any agreement hereafter made shall be ineffective to change,
modify, waive or discharge this Sublease in whole or in part unless such
agreement is in writing and signed by the party against whom enforcement of the
change, modification, waiver or discharge is sought.

                      (c) SUCCESSORS AND ASSIGNS. The terms, covenants and
conditions contained in this Sublease shall, subject to the provisions of this
Sublease relating to assignment, mortgaging and subletting, apply to, be binding
upon and inure to the benefit of the heirs, successors and assigns of the
parties hereto.

                      (d) WAIVERS. No delay or omission in the exercise of any
right or remedy of either party hereto upon any default by the other party
hereto shall impair such right or remedy or be construed as a waiver of such
default. The receipt and acceptance by Sublessor of delinquent rents or charges,
or the acceptance of partial payments of such rents or charges, shall not
constitute a waiver of any other default.

                      (e) TIME OF ESSENCE. Time is of the essence of this
Sublease.

                      (f) ATTORNEY'S FEES. If any party commences an action
against the other party arising out of or in connection with this Sublease, the
prevailing party shall be entitled to recover from the nonprevailing party the
cost and expenses of such action, including reasonable attorneys' fees and court
costs. The "prevailing party" will be determined by the court before whom the
action was brought based upon the assessment of which party's major arguments or
positions taken in the suit or proceeding could fairly be said to have prevailed
over the other party's major arguments or positions on major disputed issues in
the court's decision.

                      (g) COUNTERPARTS. This Sublease may be executed in
counterparts, each of which shall constitute an original and shall be binding
upon all parties, their successors and permitted assigns.

               10. CONDITION PRECEDENT. It shall be a condition precedent to the
parties' obligations hereunder that the Master Landlord shall have consented to
this Sublease in writing (the "Landlord's Consent") terms reasonably acceptable
to Sublessor and Sublessee.

               IN WITNESS WHEREOF, the parties hereto have executed this
Sublease as of the date first above written.

                                    EXHIBIT D

                                    SUBLEASE


               THIS SUBLEASE (this "Sublease") is entered into as of the ___ day
of _________, 1998, by and between (i) CALIFORNIA MICROWAVE, INC., a Delaware
corporation ("Sublessee"), and (ii) CALIFORNIA MICROWAVE SERVICES DIVISION,
INC., a Delaware corporation ("Sublessor").

        A. Sublessor is the current tenant under that certain Lease dated May 8,
1995, as amended by that certain First Amendment to Lease dated June 7, 1995
(collectively, the "Master Lease"), pursuant to which Sublessor is leasing
approximately 41,472 rentable square feet of office and industrial space located
at 1143 Borregas Avenue, Sunnyvale, California, as more particularly described
in the Master Lease (the "Premises"). A copy of the Master Lease is attached
hereto as Exhibit I. The current landlord under the Master Lease is AMB
Property, L.P. (the "Master Landlord"), successor in interest to the AMB
Industrial Value Added Fund. Except as otherwise defined herein, all
initial-capitalized terms used herein shall have the same meaning as is ascribed
to such terms in the Master Lease.

        B. Sublessor has agreed to sublease to Sublessee a portion of the
Premises containing approximately 10,968 rentable square feet, as outlined in
the plan attached hereto as Exhibit II (such portion of the Premises being
hereinafter referred to as the "Subleased Premises"), and Sublessee desires to
sublet the Subleased Premises from Sublessor, on the terms, covenants and
conditions contained herein.

               NOW, THEREFORE, in consideration of the mutual covenants and
promises of the parties contained herein, the parties hereto agree as follows:

               1. SUBLEASE. Sublessor subleases to Sublessee and Sublessee hires
from Sublessor the Subleased Premises, in "AS IS" condition, subject to the
Master Lease. In addition, Sublessee shall have the right to use in common with
Sublessor the reception area, cafeteria, and restrooms located in the portion of
the Premises to be retained by Sublessor, and shall have the right to use such
portion of the Premises for ingress and egress to and from such areas.

               2.     TERM.

                      (a) TERM. The term of this Sublease shall commence on the
date hereof (the "Commencement Date") and shall expire on July 31, 2000, subject
to extension as


                                       -1-

<PAGE>   68



provided in Section 2(b) below (the "Term"). Notwithstanding the foregoing, the
Commencement Date shall not be deemed to have occurred prior to the date that
the parties have closed on that certain Stock Purchase Agreement dated May __,
1998, entered into between the parties and the Landlord's Consent (as defined in
Section 10 hereof) is obtained.

                      (b) RENEWAL. The parties acknowledge that Article 39 of
the Master lease provides for one (1) option (the "Master Lease Option") to
renew the Master Lease for a term of five (5) years (the "Option Term"), from
August 1, 2000 to July 31, 2005, at an Annual Rent of 95% of the current fair
market rental for comparable space in other similar buildings in the same rental
market as of the date the Option Term is to commence. Sublessor shall exercise
the Master Lease Option in accordance with the provisions of the Master Lease,
whereupon the Term shall be automatically extended for the length of the Option
Term. In the event of any arbitration to determine rent pursuant to Article 39
of the Master Lease, the parties shall share the cost of such arbitration in
accordance with their respective percentages of the Premises (including an
equitable allocation of any areas of the Premises used in common with Sublessor)
at the time of the commencement of the Option Term.

               3.     RENT.

                      (a) BASE RENT. Commencing on the Commencement Date,
Sublessee shall pay to Sublessor during the Term as base rent for the Subleased
Premises the twenty-six and four-tenths percent (26.4%) ("Sublessee's Share") of
the Annual Rent and Monthly Installment payable under the Master Lease for the
period of the Term. Sublessee's Share was computed by dividing the rentable
square footage of the Subleased Premises (i.e., 10,968) by the rentable square
footage of the Premises (i.e., 41,472). The amounts payable pursuant to this
Section 3(a) are hereinafter referred to as "Base Rent." Payment for the first
(1st) month of the Term shall be due on the Commencement Date. Otherwise,
monthly payments of Base Rent shall be due on or before the first day of each
month during the Term.

                      (b) ADDITIONAL RENT. As additional rent, Sublessee shall
pay Sublessor Sublessee's Share of Direct Expenses and Taxes paid or incurred by
Sublessor under Article 4 of the Master Lease at the same time as such payments
are due from Sublessor to Master Landlord under the Master Lease, including any
estimated payments payable pursuant to Section 4.4 of the Master Lease.
Sublessor shall promptly provide Sublessee with estimates or statements
regarding increases in Direct Expenses and/or Taxes delivered by Master Lessor
to Sublessor under Section 4.4 of the Master


                                       -2-

<PAGE>   69

Lease. Overpayments and underpayments of Direct Expenses and Taxes shall be
handled in the same manner as provided under Section 4.5 of the Master Lease.
Payments for the calendar year 1998 shall be appropriately prorated.

                      (c) SHARED COSTS. The parties hereto acknowledge that
Sublessor may incur certain costs (of the nature shown on Exhibit III attached
hereto) with respect to the Premises which benefit both itself and Sublessee,
and Sublessee may incur certain costs (of the nature shown on Exhibit III
attached hereto) with respect to the Premises which benefit both itself and
Sublessor. Where Sublessor incurs costs which benefit Sublessee, Sublessee shall
reimburse Sublessor for its pro-rata share of those costs within thirty (30)
days of receipt of billing from Sublessor. Where Sublessee incurs costs which
benefit Sublessor, Sublessor shall reimburse Sublessee for its pro-rata share of
those costs within thirty (30) days of receipt of billing from Sublessee.
Exhibit III to this Sublease is a listing of costs which Sublessor and/or
Sublessee may incur which benefit the other party, the current estimated monthly
amount of such costs, and the allocation procedure to be used to pro-rate the
costs between the parties. The allocation procedure may be adjusted by the
mutual agreement of the parties. Costs incurred that are outside of the
categories listed on Exhibit III ("Additional Category Costs") must be agreed to
in advance in order for the paying party to seek reimbursement. The parties will
use their best efforts to agree on the most appropriate allocation procedure to
be used for Additional Category Costs and/or to reflect changing circumstances.
If the parties cannot agree, then such costs will be pro-rated as follows:

                             i)     One-half (1/2) of the cost based
                                    upon relative number of employees
                                    (including contract laborers)
                                    employed at the Premises; and

                             ii)    One-half (1/2) of the cost based upon
                                    relative rentable square footage leased at
                                    the Premises.

                      (d) LATE PAYMENTS. If any installment of Base Rent or
additional rent due from Sublessee under this Sublease shall not be received by
Sublessor within five (5) days of the date the same is due, Sublessee shall pay
to Sublessor a late charge equal to six percent (6%) of such unpaid amounts.

                      (e) PAYMENT. Base Rent and additional rent due hereunder
shall be paid by Sublessee to Sublessor without


                                       -3-

<PAGE>   70

deduction or offset, and with respect to Base Rent, without demand.

               4.     USE.  Sublessee shall use the Subleased
Premises only for purposes allowed under the Master Lease and
for no other purpose.

               5.     MASTER LEASE.

                      (a) INCORPORATION FROM MASTER LEASE. Except as modified
herein, all of the terms and conditions contained in the Master Lease are
incorporated herein as terms and conditions of this Sublease, with each
reference therein to "Landlord" and "Tenant" deemed to mean Sublessor and
Sublessee, respectively, with each reference therein to the "Premises" deemed to
mean the Subleased Premises, and with each reference therein to "Term" deemed to
mean the Term (as defined in Section 2(a) hereof). Notwithstanding the
foregoing, the following sections, paragraphs or exhibits of the Master Lease
are excluded from this Sublease or are revised as indicated:

               Section 2.1; Section 2.2; Section 3.1; Section 3.2; Article 4
               (except as provided in Section 3(b) hereof); Section 5; Section
               7.5 shall be revised to provide that Sublessor shall be
               responsible for entering into the maintenance contract for all
               heating and air conditioning systems and equipment servicing the
               Premises, and that the parties shall share proportionately the
               cost thereof; Article 9; Section 11.2(a) shall be revised to
               provide that the insurance policies to be provided by Sublessee
               pursuant to Section 11.1 of the Master Lease shall name
               Sublessor, Master Landlord and the building management company,
               if any, as additional insureds; Article 22 (Sublessee recognizes
               that the Term of this Sublease shall terminate in the event of a
               termination pursuant to this Article; Sublessee shall be entitled
               to a proportionate amount of any abatement of rent Sublessor
               receives pursuant to Section 22.2); Article 24; Article 27;
               Article 32; Article 38; Article 40; Exhibit B; Addendum
               Paragraphs 1, 2, and clause (b) of Paragraph 3.

Nothing contained in this Section 5(a) is intended to alter the parties'
agreement as to certain shared costs set forth in Section 3(c) hereof.

                      (b) RECOURSE TO MASTER LANDLORD. Notwithstanding anything
contained in Section 5(a) above, it is understood and agreed that Sublessor
shall have no obligation or responsibility to provide or perform any


                                       -4-

<PAGE>   71

service, repair, restoration, alteration or other similar obligation which is
the obligation of Master Landlord to provide or perform pursuant to the
provisions and terms of the Master Lease including, but not limited to, the
obligation of Master Landlord to make restorations or repairs after damage to
the Premises or the Building by fire or other cause or after condemnation.
Sublessee further agrees that each such obligation shall be provided or
performed by Master Landlord and not by Sublessor. If Sublessee shall notify
Sublessor that Master Landlord is not supplying services to the Subleased
Premises or performing other obligations as required under the Master Lease,
Sublessor will promptly request Master Landlord to perform such services.
Sublessor shall in no event be liable to Sublessee nor shall Sublessee's
obligations under this Sublease be impaired or reduced or the performance
thereof excused because of any failure or delay on Master Landlord's part in
providing any such services or in making any repairs or alterations, or in
performing or observing any similar obligation of Master Landlord under the
Master Lease. If Master Landlord shall default in its obligation to provide
services as required under the Master Lease to the Subleased Premises, Sublessee
shall be entitled to participate with Sublessor in the enforcement of
Sublessor's rights against Master Landlord, but Sublessor shall have no
obligation to bring any action or proceeding or otherwise act to enforce
Sublessor's rights against Master Landlord. If, after written request from
Sublessee, Sublessor shall fail or refuse, within a reasonable period of time,
to institute an action or proceeding for the enforcement of Sublessor's rights
against Master Landlord with respect to a failure to provide services required
to be provided to the Subleased Premises under the Master Lease, Sublessee shall
have the right to take such action in its own name, and for that purpose and
only to such extent, shall have the same rights as Sublessor under the Master
Lease. If any such action against Master Landlord in Sublessee's name shall be
barred by reason of lack of privity, nonassignability or otherwise, Sublessee
may take such action in Sublessor's name provided Sublessee has obtained the
prior written consent of Sublessor, which consent shall not be unreasonably
withheld; provided, however, that Sublessee shall indemnify and hold Sublessor
harmless from and against any and all liability, loss, claims, demands, suits,
penalties or damage (including, without being limited to, reasonable attorneys'
fees and expenses) which Sublessor may incur or suffer by reason of such action.
Sublessor shall provide Sublessee with a copy of all notices delivered by
Sublessor to the Master Landlord pursuant to this Section 5(b).

                      (c) CONSENT OF MASTER LANDLORD. Whenever the provisions of
the Master Lease that have been incorporated as


                                       -5-

<PAGE>   72

provisions of this Sublease require the written consent of Master Landlord, said
provisions shall be construed to require the written consent of both Master
Landlord and Sublessor.

                      (d) OBLIGATIONS RE MASTER LEASE. Sublessor agrees to
maintain the Master Lease in full force and effect, except to the extent any
failure to maintain the Master Lease is due to the failure of Sublessee to
comply with any of its obligations under this Sublease. During the Term,
Sublessor shall not enter into any amendment of the Master Lease that will
diminish Sublessee's rights or increase Sublessee's obligations hereunder.

                      (b) ENTIRE AGREEMENT. This Sublease represents the entire
agreement between the parties to this Sublease and supersedes all prior
agreements between the parties, whether written or oral. There are no
representations between Sublessor and Sublessee other than those contained in
this Sublease. Any agreement hereafter made shall be ineffective to change,
modify, waive or discharge this Sublease in whole or in part unless such
agreement is in writing and signed by the party against whom enforcement of the
change, modification, waiver or discharge is sought.

                      (c) SUCCESSORS AND ASSIGNS. The terms, covenants and
conditions contained in this Sublease shall, subject to the provisions of this
Sublease relating to assignment, mortgaging and subletting, apply to, be binding
upon and inure to the benefit of the heirs, successors and assigns of the
parties hereto.

                      (d) WAIVERS. No delay or omission in the exercise of any
right or remedy of either party hereto upon any default by the other party
hereto shall impair such right or remedy or be construed as a waiver of such
default. The receipt and acceptance by Sublessor of delinquent rents or charges,
or the acceptance of partial payments of such rents or charges, shall not
constitute a waiver of any other default.

                      (e) TIME OF ESSENCE. Time is of the essence of this
Sublease.

                      (f) ATTORNEY'S FEES. If any party commences an action

prevailing party shall be entitled to recover from the nonprevailing party the
cost and expenses of such action, including reasonable attorneys' fees and court
costs. The "prevailing party" will be determined by the court before whom the
action was brought based upon the assessment of which party's major arguments or
positions taken in the suit or proceeding could fairly be said to have prevailed
over the other party's major arguments or positions on major disputed issues in
the court's decision.

                      (g) COUNTERPARTS. This Sublease may be executed in
counterparts, each of which shall constitute an original and shall be binding
upon all parties, their successors and permitted assigns.

               10. CONDITION PRECEDENT. It shall be a condition precedent to the
parties' obligations hereunder that the Master Landlord shall have consented to
this Sublease in


                                       -7-

               (d) The 29% was computed by adding to the 10,968 square feet
               occupied solely by CMI its pro-rata share of the 3722 square feet

                      10,968 plus 1080 = 12,048 = 29.05%

                  CALIFORNIA MICROWAVE SELLS SERVICES DIVISION
                             FOR $8 MILLION IN CASH

SUNNYVALE, CALIFORNIA - CALIFORNIA MICROWAVE, INC. (NASDAQ NATIONAL MARKET:
CMIC) announced today that on May 29, 1998, it completed the sale of its
Services Division to Telscape International, Inc., a publicly traded Houston,
TX-based telecommunications company, for approximately $8 million in cash. The
transaction is subject to post-closing adjustments for changes in net assets
between April 25, 1998, and the closing of the transaction.

REFOCUSING ON GROWTH BUSINESS

On April 23, 1998, California Microwave announced its strategic repositioning
plan for growth, and stated that its Services Division was being divested.
According to Frederick D. Lawrence, California Microwave's chairman and chief
executive officer, "Even though our Services Division is a profitable
operation, its business does not meet California Microwave's EVA requirements
and its products and services do not fit with our new strategic focus on
high-growth, commercial wireless markets. We will use the divestiture proceeds
to continue our share buyback program and to invest in the wireless broadband
access products and solutions markets that are growing at rates greater than
20%."

California Microwave also indicated in its April 23, 1998, press release that
as part of its operational excellence initiative, operations and business
processes were being reviewed and refocused to ensure successful execution of
the company's new growth strategy. As a result of the review process,
California Microwave will incur certain costs and expenses in its fourth
quarter relating to: combining its two commercial terrestrial businesses,
Microwave Radio Communications and Microwave Data Systems; combining its
government businesses, Airborne Systems Integration and Government Electronics;
streamlining its product lines; and consolidating and updating its four
separate information systems related to its commercial businesses. California
Microwave currently anticipates that all but $2-4 million of those costs and
expenses will be covered by the estimated $6 million pre-tax gain to be
recognized on the sale of its Services Division.

Statements made in this press release that are not historical facts, including
any statements about expectations for fiscal year 1998 and beyond are
forward-looking statements, involving certain risks and uncertainties. Factors
that could cause the company's actual results to differ materially from
management's projections, estimates and expectations include, but are not
limited to, delays in the receipt of orders or in the shipment of products, the
company's success in implementing its strategic plan, and other factors
referred to in the company's Securities and Exchange Commission filings.

California Microwave, Inc. (http://www.calmike.com) is a leading U.S. supplier
of satellite earth station and microwave radio infrastructure products and
information and collection systems. Its focus is on transmission of high-speed
data, especially for Internet traffic, via satellite and terrestrial wireless
communications.
