                                  THE CLOSING

                 2.1      Place and Date.  The closing of the sale and purchase
of the Assets (the "Closing") and the assumption of the Assumed Liabilities
shall take place at 10:00 A.M. local time on the 26th day of January, 1998 at
the offices of Whitman Breed Abbott & Morgan LLP, 200 Park Avenue, New York, NY
10166, or such other time and place upon which the parties may agree.  The day
on which the Closing actually occurs is herein sometimes referred to as the
"Closing Date."

                 2.2      Purchase Price.  On the terms and subject to the
conditions set forth in this Agreement, Buyer agrees to pay to Seller at the
Closing an aggregate of U.S. $27 million, subject to adjustment as provided for
in Section 2.7 (the "Purchase Price"), and to assume the Assumed Liabilities as
provided in Section 2.4.  The Purchase Price shall be paid by the wire transfer

solely for this purpose the agreements contained in Section 5.1(f), in
accordance with Section 1060 of the Code as mutually agreed to by the parties
within 180 days following the Closing.  All such mutually agreed to allocations

prepared by independent firm(s) selected by Buyer and approved by Seller (such
approval not to be unreasonably withheld or delayed), and (b) used by each
party in preparing any filings required pursuant to Section 1060 of the Code or
any similar provisions of state or local law and all relevant income and
franchise tax returns, subject to adjustment to reflect the adjustment to the
Purchase Price provided for in Section 2.7.  Neither Buyer nor Seller will take
any position before any taxing authority or in any judicial proceeding that is
inconsistent with such mutually agreed to allocations without the prior consent
of the other party.  The parties shall in good faith exercise reasonable
efforts to support such reported allocations in any audit proceedings initiated
by any taxing authority.

                 2.4      Assumption of Liabilities.  Subject to the terms and
conditions set forth herein, at the Closing, Buyer shall assume and agree to
pay, honor and discharge when due only the following liabilities and

obligations of Seller under all retention incentive agreements as set forth in
Schedule


                                      -5-

2.4(a), but only to the extent that such payment obligations relate to the
failure of Buyer to hire employees of the STS Division or the involuntary
termination by Buyer without cause of the employment of any Transferred
Employee after the Closing; (b) all product warranty obligations of the
Business; (c) all liabilities and obligations of Seller to be performed from

                          (i)     the Excluded Assets;

                          (j)     all Environmental Liabilities and Costs

                                      -7-
<PAGE>

extent based on or arising out of or based upon product liability with respect
to products shipped or sold prior to the Closing; or

                          (n)     all intercompany obligations and liabilities

accounts payable reflected on the Final Closing Statement of Net Assets.

                 2.6      Consent of Third Parties.  Notwithstanding anything
to the contrary in this Agreement, this Agreement shall not constitute an
agreement to assign or transfer any Governmental Approval, instrument,
contract, lease, permit or other agreement or arrangement or any claim, right
or benefit arising thereunder or resulting therefrom if an assignment or
transfer or an attempt to make such an assignment or transfer without the
consent of a third party would constitute a breach or violation thereof or
affect adversely the rights of Buyer or Seller thereunder; and any transfer or
assignment to Buyer by Seller of any interest under any such Governmental
Approval, instrument, contract, lease, permit or other agreement or arrangement
that requires the consent of a third party shall be made subject to such
consent or approval being obtained.  In the event any such consent or approval
is not obtained on or prior to the Closing Date, Seller shall (i) continue to
use all reasonable efforts to obtain any such approval or consent after the
Closing Date until such time as such consent or approval has been obtained
without any third party cost to Buyer, (ii) hold such Governmental Approval,
instrument, contract, lease, permit or other agreement or arrangement on behalf
of Buyer, (iii) cooperate with Buyer in any lawful arrangement to provide that
Buyer shall receive the benefits under any such Governmental Approval,

including performance by Seller, as agent, and (iv) enforce and perform for the
account of Buyer any rights of Seller arising from such Government Approval,
instrument, contract, lease, permit or other agreement or arrangement, provided
that Buyer shall undertake to pay or satisfy the corresponding liabilities for
the enjoyment of such benefit to the extent Buyer would have been responsible
therefor if such consent or approval had been obtained.  Nothing in this
Section 2.6 shall be deemed a waiver by Buyer of its right to receive an
effective assignment of all of the Assets.

                 2.7      Adjustment of Purchase Price.

                          (a)     Calculation of Adjustment.  The Purchase
Price shall be (i) increased by the amount that the Closing Date Net Assets (as
hereinafter defined), are greater than $25,099,080 (which amount is the book
value of the net assets as shown on the adjusted September Balance Sheet (the
"Target Net Assets"); or (ii) decreased by the amount that the Closing Date Net
Assets are less than the Target Net Assets.  The term "Closing Date Net Assets"
as used herein shall mean the book value of the Assets set forth on the Final
Closing


                                      -8-
<PAGE>

Statement of Net Assets (as hereinafter defined) in excess of the amount of the
Assumed Liabilities set forth on the Final Closing Statement of Net Assets,
determined in accordance with the procedures set forth below.  The amount of
any decrease or increase to the Purchase Price pursuant to this Section 2.7(a)
plus interest from and including the Closing Date to but excluding the date of
payment at the Prime Rate (as hereinafter defined) shall be paid by Seller or
Buyer, as the case may be, by wire transfer in immediately available funds
within five (5) business days after the Final Closing Statement of Net Assets
is agreed to by Seller and Buyer or is determined by the Neutral Auditor (as
hereinafter defined).  For purposes of this Agreement, "Prime Rate" means the
prime rate of interest in effect on the Closing Date as stated in the "Money
Rates" section of the Wall Street Journal.

                          (b)     Preparation of Closing Statement of Net
Assets.  As soon as practicable, and in any event within sixty (60) days after
the Closing Date, Seller shall cause Ernst & Young LLP ("E&Y") to prepare an
audited statement of net assets for the Business consisting of the Assets and
the Assumed Liabilities, as of the close of business on the Closing Date
determined on a pro forma basis as if the parties hereto had not consummated
the transactions contemplated by this Agreement (the "Closing Statement of Net
Assets"), to be prepared in accordance with United States generally accepted
accounting principles ("GAAP") applied on a basis consistent with the September
30, 1997 Financial Statements (including the September Balance Sheet) through
full application of the policies and procedures used in preparing the September
30, 1997 Financial Statements (including the September Balance Sheet) and
taking into account the type of adjustments included in the September Balance
Sheet set forth in Schedule 3.4, and with changes in contract estimates at
completion ("EAC's") and estimates to complete ("ETC's") determined on a basis
consistent with the method used for the determination of the September 30, 1997
Financial Statements (including the September Balance Sheet); provided that,
for purposes of the Closing Statement of Net Assets, the cash and cash
equivalents held in non-US bank accounts for the benefit of the STS Division
shall be transferred to Buyer and shall be reflected as assets of the STS
Division and shall be included in the calculation of any Purchase Price
adjustment required by this Section.  The Closing Statement of Net Assets shall
be accompanied by the report of E&Y thereon and by a certificate of Seller's
Chief Financial Officer, each of which shall state that the Closing Statement
of Net Assets presents fairly, in all material respects, the Assets and Assumed
Liabilities presented on such statement as provided for in this Agreement at
the Closing Date in conformity with GAAP consistently applied with the
September 30, 1997 Financial Statements, except that it does not contain all
the notes required by GAAP.  Buyer shall provide Seller, E&Y and the Neutral
Auditor such access to the Books and Records as may reasonably be required for
the preparation and/or review of the Closing


                                      -9-
<PAGE>

Statement of Net Assets. All fees and expenses of E&Y relating to the
preparation of the Closing Statement of Net Assets shall be borne equally by
Seller and Buyer.

                          (c)     Review of Closing Statement of Net Assets.
After receipt of the Closing Statement of Net Assets, 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 its accountants to the extent required to complete their review of the
Closing Statement of Net Assets including work papers used in preparation
thereof. Unless the Buyer delivers written notice to Seller on or prior to the
30th day after receipt of the Closing Statement of Net Assets specifying in
reasonable detail all disputed items and the basis therefor, the parties shall
be deemed to have accepted and agreed to the Closing Statement of Net Assets.
If Buyer so notifies the Seller of an objection to the Closing Statement of Net
Assets, the parties shall, within thirty (30) days following the date of such
notice (the "Resolution Period") attempt to resolve their differences and any
resolution by them as to any disputed amount 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 (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 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.  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 the
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.  The term "Final Closing Statement of
Net Assets," as hereinafter used, shall mean the definitive Closing Statement
of Net Assets agreed to by Seller and Buyer in accordance with Section 2.7(c)
or the definitive Closing Statement of Net Assets resulting


                                      -10-
<PAGE>

from the determination made by the Neutral Auditor in accordance with this
Section 2.7(d) (in addition to those items theretofore agreed to by Seller and
Buyer).

the transactions contemplated hereby, have been duly authorized by all
requisite corporate action of Seller.  Seller has duly executed and delivered
this Agreement.  This Agreement is a legal, valid and binding obligation of
Seller, enforceable against it in accordance with its terms, except as such

                          (b)     Seller is duly qualified or licensed to do
business and is in good standing in each of the jurisdictions in which the
operation of the Business or the character of the properties owned, leased or
operated by it in connection with the Business makes such qualification or
licensing necessary, except where the failure to be so qualified or licensed

Schedule 3.2(b).

                          (c)     Seller has delivered to Buyer complete and

performance by Seller of this Agreement and the consummation of the
transactions contemplated hereby, do not and will not conflict with or result
in a violation of or a default under (with or without the giving of notice or
the lapse of time or both), or result in the acceleration of or give rise to
any party the right to terminate, modify or cancel under, or result in the loss
of any rights, privileges, options or alternatives under, or result in the
creation of any Lien on any assets of Seller (including the Assets) under (i)
any Applicable Law applicable to Seller or any of the Assets, (ii) the
certificate of incorporation or by-laws of Seller or (iii) except as set forth

written notice has been received from the mortgagee(s) asserting that a default
or breach exists thereunder or under any note or other obligation secured
thereby which remains uncured.  Seller knows of no default, or event which with
notice or the passage of time will constitute a default, under the Existing
Mortgage(s) or under any note or other obligation secured thereby which has
occurred and is continuing.  Seller has delivered to Buyer complete copies of
the documents constituting the Existing Mortgage(s) and the note(s) secured
thereby.

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 respective affiliates to which

by Seller.  Buyer agrees that it will not, and will cause the Business not to,

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 its business,
except as expressly permitted by clause (ii) of this Section 5.2(d).

                                  (ii)     For a period of six months from the

surety bonds in substitution for the letters of credit and bonds referred to in
Schedule 5.2(e)


                                      -30-

attached hereto and agrees to reimburse Seller for any out-of-pocket bank fees

outstanding from and after 30 days after the Closing Date.

                          (f)     Reimbursement of Certain Severance
Obligations.  Schedule 5.2(f) lists three severance agreements heretofore

Executive becomes employed by Buyer as of the Closing Date as a Transferred
Employee, (ii) there shall occur thereafter a termination by such Executive of
his employment with Buyer for Good Reason (as defined below) within one year
after the Closing Date, and (iii) as a result of the termination of employment
of the type described in clause (ii) above, Seller shall be obligated to make
any cash payment to such Executive pursuant to the provisions of the Severance
Agreement with such Executive, then Buyer shall reimburse Seller for any such
cash payment it so makes to such Executive, such reimbursement to occur
promptly upon receipt by Buyer of evidence of the making of such payment;
provided, however, that the reimbursement obligation of Buyer to Seller under
this Section 5.2(f) with respect to any Executive shall not in any event exceed
the amount that would have been payable to such Executive under his retention
incentive agreement that is listed on Schedule 2.4(a) in the event of an
involuntary termination by Buyer without cause of the employment of such
Executive after the Closing; provided further, however, Buyer shall have no
reimbursement obligation to Seller under this Section 5.2(f) if Buyer otherwise
is obligated to make a payment to the Executive under his retention incentive
agreement pursuant to Section 2.4(a).

                 As used herein, "Good Reason" means the occurrence of any of
the following:  (x) the assignment to the Executive in question of duties
inconsistent with, or a substantial alteration in the nature or status of, such
Executive's responsibilities with respect to the Business at the STS Division
immediately before the Closing; (y) a reduction in the Employee's base salary
or in the benefits that Buyer is required to provide such Executive pursuant to
Section 7.2; or (z) such Executive's relocation to a work site requiring an
increase in one-way commute from such Executive's residence of more than 35

programs based on the achievement of financial targets, on a basis comparable

Date.  Buyer will provide or establish a cash incentive bonus program(s) based
on the achievement of financial targets to those Transferred Employees who
currently are eligible for cash incentive bonus program(s) of Seller based on
the achievement of financial targets, which cash incentive program(s) of Buyer
shall be comparable in the aggregate to such cash incentive bonus program(s) of
Seller.

apparent that any of such conditions will not be, fulfilled by 5:00 p.m.
California time on February 15, 1998, unless such failure shall be due to the
failure of Buyer to


                                      -36-
<PAGE>

perform or comply with any of the covenants, agreements or conditions hereof to
be performed or complied with by it prior to the Closing; or

                          (d)     by Seller by written notice to Buyer if (i)
the representations and warranties of Buyer shall not have been true and
correct in all material respects as of the date when made or (ii) if any of the

the failure of Seller to perform or comply with any of the covenants,
agreements or conditions hereof to be performed or complied with by it prior to
the Closing.

                 8.2      Effect of Termination.  In the event of the

                 9.1      By Seller.  Subject to the terms and conditions of
this Article IX, Seller covenants and agrees to defend, indemnify and hold
harmless Buyer, its officers, directors, employees, agents, advisers,
representatives and Affiliates (collectively, the "Buyer Indemnitees") from and
against, and pay or reimburse Buyer Indemnitees for, any and all claims,
liabilities, obligations, losses, fines, costs, proceedings, deficiencies or
damages (whether absolute, accrued, conditional or otherwise and whether or not
resulting from third party claims), including out-of-pocket expenses and
reasonable attorneys' fees incurred in the investigation or defense of any of
the same or in asserting any of their respective rights hereunder
(collectively, "Losses"), resulting from or arising out of:

                            (i)   Any misrepresentation or breach of any
warranty of Seller contained in this Agreement; provided that any claim for
indemnification by Buyer under this clause (i) may be made no later than 18
months from and after the Closing Date, excepting only that any claim for
misrepresentation or breach of warranty under Sections 3.6, 3.10(a), 3.18(a),

expiration of the period of the applicable statute of limitations;


                                      -37-
<PAGE>

                           (ii)   any failure of Seller to perform any covenant
or agreement made or contained in this Agreement or fulfill any obligation in
respect thereof;

                          (iii)   any Excluded Liabilities;

                           (iv)   any and all Benefit Liabilities in respect of
Employees except, with respect to Transferred Employees, to the extent assumed
by Buyer pursuant to Article VII; and

                            (v)   any product liability claim with respect to
products manufactured by Seller and sold prior to the Closing.

                 Seller shall not be required to indemnify Buyer Indemnitees
with respect to any claim for indemnification resulting from or arising out of
matters described in clauses (i) and (v) above pursuant to this Section unless
and until the aggregate amount of all claims against Seller exceeds $270,000
and then only to the extent such aggregate amount exceeds $270,000.  Claims
thereafter may be asserted regardless of amount.  Seller's maximum liability to
Buyer Indemnitees under clauses (i) and (v) of this Section shall not exceed
$13,750,000.

                 9.2      By Buyer.  Subject to the terms and condition of this
Article IX, Buyer covenants and agrees to defend, indemnify and hold harmless
Seller and its officers, directors, employees, agents, advisers,
representatives and Affiliates (collectively, the "Seller Indemnitees") from
and against any and all Losses resulting from or arising out of:

                            (i)   any misrepresentation or breach of warranty
of Buyer contained in this Agreement or in any Schedule of Buyer; provided that
any claim for indemnification by Seller under this paragraph (i) may be made no
later than 18 months from and after the Closing Date;

                           (ii)   any failure of Buyer to perform any covenant
or agreement made or contained in the Agreement or fulfill any other obligation
in respect thereof;

                          (iii)   the Assumed Liabilities;

                           (iv)   claims made on or drawings under any of the

attached hereto;


                                      -38-
<PAGE>

                            (v)   the use by Buyer of any Seller tradenames or
trademarks after the Closing Date other than as permitted or contemplated by
Section 5.2(d); and

                           (vi)   the operation of the Business by Buyer or
Buyer's ownership, operation or use of the Assets following the Closing Date
except to the extent that such Loss is the result of any action of Seller prior
to the Closing.

                 Buyer shall not be required to indemnify Seller Indemnitees
with respect to any claim for indemnification resulting from or arising out of
matters described in clause (i) above pursuant to this Section unless and until
the aggregate amount of all claims against Buyer exceeds $270,000 and then only
to the extent such aggregate amount exceeds $270,000.  Buyer's maximum
liability to Seller Indemnitees under clause (i) of this Section shall not
exceed $13,750,000.

                 9.3      Adjustments to Indemnification Payments.  Any payment
made by Seller to Buyer Indemnitees, on the one hand, or by Buyer to Seller
Indemnitees, on the other hand, pursuant to this Article IX in respect of any
claim shall be net of any insurance proceeds realized by and paid to the
Indemnified Party in respect of such claim.  The Indemnified Party shall use
its reasonable efforts to make insurance claims relating to any claim for which
it is seeking indemnification pursuant to this Article IX; provided that the
Indemnified Party shall not be obligated to make such an insurance claim if the
Indemnified Party in its reasonable judgment believes that the cost of pursuing
such an insurance claim together with any corresponding increase in insurance
premiums or other chargebacks to the Indemnified Party, as the case may be,
would exceed the value of the claim for which the Indemnified Party is seeking
indemnification.

                 9.4      Indemnification Procedures.  In the case of any claim
asserted by a third party against a party entitled to indemnification under
this Agreement (the "Indemnified Party"), notice shall be given by the
Indemnified Party to the party required to provide indemnification (the
"Indemnifying Party") promptly after such Indemnified Party has actual
knowledge of any claim as to which indemnity may be sought, and the Indemnified
Party shall permit the Indemnifying Party (at the expense of such Indemnifying
Party) to assume the defense of any third party claim or any litigation with a
third party resulting therefrom, provided that (i) the counsel for the
Indemnifying Party who shall conduct the defense of such claim or litigation
shall be reasonably satisfactory to the Indemnified Party, (ii) the Indemnified
Party may participate in such defense at such Indemnified Party's expense, and
(iii) the omission by any Indemnified Party to give notice as provided herein
shall not relieve the


                                      -39-
<PAGE>

Indemnifying Party of its indemnification obligation under this Agreement except
and only to the extent that such Indemnifying Party is materially damaged as a
result of such failure to give notice. Except with the prior written consent of
the Indemnified Party, no Indemnifying Party, in the defense of any such claim
or litigation, shall consent to entry of any judgment or enter into any
settlement that provides for injunctive or other nonmonetary relief affecting
the Indemnified Party or that does not include as an unconditional term thereof
the giving by each claimant or plaintiff to such Indemnified Party of a release
from all liability with respect to such claim or litigation. In the event that
the Indemnified Party shall in good faith determine that the conduct of the
defense of any claim subject to indemnification hereunder or any proposed
settlement of any such claim by the Indemnifying Party might be expected to
affect adversely the Indemnified Party's Tax liability or the ability of Buyer
to conduct its business, or that the Indemnified Party may have available to it
one or more defenses or counterclaims that are inconsistent with one or more of
those that may be available to the Indemnifying Party in respect of such claim
or any litigation relating thereto, the Indemnified Party shall have the right
at all times to take over and assume control over the defense, settlement,
negotiations or litigation relating to any such claim at the sole cost of the
Indemnifying Party, provided that if the Indemnified Party does so take over and
assume control, the Indemnified Party shall not settle such claim or litigation
without the written consent of the Indemnifying Party, such consent not to be
unreasonably withheld. In the event that the Indemnifying Party does not accept
the defense of any matter as above provided, the Indemnified Party shall have
the full right to defend against any such claim or demand and shall be entitled
to settle or agree to pay in full such claim or demand. In any event, the
Indemnifying Party and the Indemnified Party shall cooperate in the defense of
any claim or litigation subject to this Article IX and the records of each shall
be available to the other with respect to such defense.

                 9.5      Expiration of Representations and Warranties, etc.
All representations and warranties contained in this Agreement shall survive
the Closing for a period of 18 months; provided that the representations and
warranties stated in Sections 3.6, 3.10(a), 3.18(a), 3.19 and 3.21 shall
survive the Closing for the applicable statute of limitations.

                 9.6      Exclusive Remedy.  The indemnifications provided for
in this Article IX 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 jurisdiction of the courts of the State of New York, and the Federal courts
of the United States of America located in the Southern District of New York
solely in respect of the interpretation and enforcement of the provisions of
this Agreement and of the documents referred to in this Agreement, and hereby

against whom enforcement of the amendment, modification, discharge or waiver is
sought.  Any such waiver shall constitute a waiver only with respect to the
specific matter described in such writing and shall in no way impair the rights
of the party granting such waiver in any other respect or at any other time.

under any of the provisions of this Agreement, nor the failure by any of the
parties, on one or more occasions, to enforce any of the provisions of this
Agreement or to exercise any right or privilege hereunder, shall be construed
as a waiver of any other breach or default of a similar nature, or as a waiver
of any of such provisions, rights or privileges hereunder.

                 10.6     Arbitration Procedure.

                          (a)     Buyer and Seller agree that the arbitration
procedure set forth below shall be the sole and exclusive method for resolving
and remedying any and all disputes regarding claims for money damages based
upon, arising out of or in any way connected with this Agreement or the
transactions contemplated herein (the "Disputes").  Nothing in this Section
10.6 shall prohibit a party hereto from instituting litigation to enforce any
Final Determination (as defined below).  The parties hereby agree and
acknowledge that, except as otherwise provided in this Section 10.6 or in the
Commercial Arbitration Rules of the American Arbitration Association as in
effect from time to time, the arbitration procedures and any Final
Determination hereunder shall be governed by and shall be enforced pursuant to
the Uniform Arbitration Act as in effect in the State of New York.

                          (b)     In the event that any party asserts that
there exists a Dispute, such party shall deliver a written notice to each other
party involved therein specifying the nature of the asserted Dispute and
requesting a meeting to attempt to resolve the same.  If no such resolution is
reached within 45 days after such delivery of such notice, the party delivering
such notice of Dispute (the "Disputing Person") may, within 75 days after
delivery of such notice, commence arbitration hereunder by delivering to each
other party involved therein a notice of arbitration (a "Notice of
Arbitration") and by filing a copy of such Notice of Arbitration with the New
York City office of the American


                                      -51-
<PAGE>

Arbitration Association.  Such Notice of Arbitration shall specify the matters
as to which arbitration is sought, the nature of any Dispute, the claims of
each party to the arbitration and the amount and nature of damages or other
relief sought to be recovered as a result of any alleged claim and any other
matters required by the Commercial Arbitration Rules of the American
Arbitration Association as in effect from time to time to be included therein.

                          (c)     Buyer and Seller each shall select one
arbitrator expert in the subject matter of the Dispute (the arbitrators so
selected shall be referred to herein as "Buyer's Arbitrator" and "Seller's
Arbitrator," respectively).  In the event that either party fails to select an
arbitrator as set forth herein within 30 days after the delivery of a Notice of
Arbitration, then the matter shall be resolved by the arbitrator selected by
the other party.  Seller's Arbitrator and Buyer's Arbitrator shall select a
third independent, neutral arbitrator expert in the subject matter of the
Dispute, and the three arbitrators so selected shall resolve the Dispute
according to the procedures set forth in this Section 10.6. If Seller's
Arbitrator and Buyer's Arbitrator are unable to agree on a third arbitrator
within 20 days after their selection, Seller's Arbitrator and Buyer's
Arbitrator shall each prepare a list of three independent arbitrators.
Seller's Arbitrator and Buyer's Arbitrator shall each have the opportunity to
designate as objectionable and eliminate one arbitrator from the other
arbitrator's list within ten days after submission thereof, and the third
arbitrator shall then be selected by lot from the arbitrators remaining on the
lists submitted by Seller's Arbitrator and Buyer's Arbitrator.

                          (d)     The arbitrators selected pursuant to Section
10.6(c) shall determine the allocation of the costs and expenses of
arbitration.

                          (e)     The arbitration shall be conducted in New
York City, under the Commercial Arbitration Rules of the American Arbitration
Association as in effect from time to time, except as otherwise set forth
herein or as modified by the agreement of Buyer and Seller.  The arbitrators
shall conduct the arbitration such that a final result, determination, finding,
judgment and/or award (the "Final Determination") is made or rendered as soon
as practicable, but in no event later than 120 days after the delivery of the
Notice of Arbitration nor later than ten days following completion of the
arbitration.  The Final Determination shall be made in writing, shall state the
basis for such determination and shall be agreed upon and signed by the sole
arbitrator or by at least two of the three arbitrators (as the case may be).
The Final Determination shall be final and binding on all parties, and there
shall be no appeal from or reexamination of the Final Determination, except for
fraud, perjury, evident partiality or misconduct by an arbitrator prejudicing
the rights of any party and to correct manifest clerical errors.

                          (f)     Buyer and Seller may enforce any Final
Determination in any state or federal court having jurisdiction over the
Dispute.  For the purpose of any action or proceeding instituted with respect
to any Final Determination, each party hereto hereby irrevocably submits to the
jurisdiction of such courts, irrevocably consents to the service of process by
registered mail or personal service and hereby irrevocably waives, to the
fullest extent permitted by law, any objection which it may have or hereafter
have as to personal jurisdiction, the laying of the venue of any such action or
jurisdiction, the laying of the venue of any such action or proceeding brought
in any such court and any claim that any such action or proceeding brought in
any court has been brought in an inconvenient form.

                 10.7     Attorneys Fees.  In the event any party hereto
initiates any legal action arising out of or in connection with this Agreement,
the prevailing party shall be entitled to recover from the other party all
reasonable attorneys' fees, expert witness fees and expenses incurred by the
prevailing party in connection therewith.

                 10.8     Liability for Transfer Taxes.  Buyer and Seller shall
each be responsible for and pay in a timely manner 50% of all sales (including,
without limitation, bulk sales), use, value added, documentary, stamp, gross
receipts, registration, transfer, conveyance, excise, recording, license and
other similar Taxes and fees ("Transfer Taxes"), arising out of or in
connection with or attributable to the transactions effected pursuant to this
Agreement.  Each party hereto shall prepare and timely file all Tax Returns
required to be filed in respect of Transfer Taxes (including, without
limitation, all notices required to be given with respect to bulk sales taxes)
that are the primary responsibility of such party under applicable law;
provided, however, that such party's


                                      -53-
<PAGE>

preparation of any such Tax Returns shall be subject to the other party's
approval, which approval shall not be withheld or delayed unreasonably.

                 IN WITNESS WHEREOF, the parties have duly executed this

      3. SIVAM Project.

            (a) It is the understanding of the parties that in connection with
the SIVAM project proposals, as currently proposed or as may otherwise be
amended (the "SIVAM Proposals"), L-3 shall have exclusive access to and
communication with Raytheon Corporation ("Raytheon"), whether oral or written,
exclusive of CMI or any of its subsidiaries (including, without limitation,
CMI's Microwave Networks division (the "MN Division"), CMI's Microwave Data
Systems division ("Data Systems") and EF Data, with respect to or in connection
with the SIVAM Project including, without limitation, any proposal, discussion,
marketing, negotiation, pricing, settlement, procurement, arrangement or
understanding with respect to the SIVAM Project.

            (b) From the Closing Date to December 31, 1998 (the "Supply
Period"), CMI shall, and shall cause its subsidiaries (including EF Data) to,
deliver to L-3 the products specified in the SIVAM Proposals (the "SIVAM
Products") in accordance with the quantities, product specifications and time
period proposed by such divisions in the SIVAM Proposals, and L-3 shall
purchase, during such Supply Period, the SIVAM Products from such divisions or
subsidiaries in accordance with the SIVAM Proposals, provided that:

                  (i) CMI accepts the terms and conditions of and performs its
duties under, as subcontractor to L-3, the contract or agreement awarded by
Raytheon to L-3 for the SIVAM Project, including, without limitation, payments
made under a vendor trust arrangement generally required by Raytheon; and

                  (ii) the pricing for each SIVAM Product quoted by CMI
(including EF Data, the MN Division and Data Systems) is competitive with, and
in no event more than 5% above, any proposal made in good faith by a legitimate
party which seeks to sell such SIVAM Product to L-3 and which agrees to perform
the duties and obligations as a subcontractor to L-3 under


                                      -2-
<PAGE>

the SIVAM Project with respect to such Product. In the event that L-3 is
permitted to purchase a SIVAM Product from a party other than CMI or EF Data
pursuant to this clause (ii) because that product has not met the conditions set
forth in this clause (ii), L-3 will remain obligated to purchase from CMI all of
the other SIVAM Products so long as those products meet the conditions in this
clause (ii) and clause (i) above and subject to the other terms and conditions
hereof.

      As used herein, the term "Product" shall mean a STS Product or a SIVAM
Product.

      4. Prices.

            (a) Source Products. CMI shall sell (or cause its subsidiaries to
sell) each Source Product to L-3 at the unit price (the "Unit Price") listed for
such Source Products on Schedule 4(a) attached hereto. The prices set forth in
Schedule 4(a) are not subject to increase during the first six months from the
Closing Date. Thereafter, CMI, or its subsidiaries, may increase such prices,
except that in no event shall (i) the Unit Price of any Source Product be less
favorable than the unit price given to other customer for such Source Product in
like quantities and (ii) any such increase in price increase the gross margin
percentage of CMI or its subsidiaries with respect to such Source Product from
its current gross margin percentage thereon. Upon L-3's written request, CMI
will provide L-3 with reasonable access during normal business hours to the
books and records of CMI and its subsidiaries for the sole purpose of
verifying the gross margin percentages with respect to the Source Products.

            (b) STS Products. CMI shall sell (or cause its subsidiaries to
sell) the STS Products, other than the Source Products, at prices no less
favorable than the prices given to other customers of such products in like
quantities.

            (c) Services. L-3 shall provide the Services to CMI at prices no
less favorable than the prices given to other customers of such Services in like
quantities.

      5. Additional Terms and Conditions.

            (a) CMI Terms and Conditions. Any sale of the STS Products by CMI or
any of its subsidiaries under this Agreement shall be subject to and governed by
the then-current standard terms and conditions (including as to warranty) of
CMI (or its subsidiaries), which terms and conditions shall be no less
favorable that those given to other customers for the same or similar products.

            (b) L-3 Terms and Conditions. Any sale of the Services by L-3 under
this Agreement shall be subject to and governed by the then-current standard
terms and conditions (including as to warranty) of L-3, which terms


                                      -3-
<PAGE>

and conditions shall be no less favorable that those given to other customers
for the same or similar services.

       6. Specifications. CMI shall, or cause its subsidiaries to, manufacture
and deliver the STS Products in accordance with the electrical, mechanical,
physical, environmental and other specifications as in effect as of the Closing
Date, or if the STS Product is a non-standard product, then according to the
specifications agreed to in writing by L-3 and CMI from time to time. In the
event an improvement or a technical change in the specifications of the STS
Products is made by CMI, CMI shall be required to provide the STS Products which
meet such improved or changed specifications; provided, however, that no such
improvement or change in specifications shall be made to LYNXX without the prior
written consent of L-3. CMI shall, or cause its subsidiaries to, manufacture and
deliver the SIVAM Products to L-3 in accordance with the specifications therefor
in the SIVAM Proposals.

       7. Maintenance of Standards. If CMI 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 CMI with respect to
new variations of the standard Products, then L-3 shall have such remedies as
may be provided in the then-current standard terms and conditions of CMI, and,
if CMI fails to cure any such deficiency in any Product within 60 days after
written notice thereof by L-3, L-3 shall no longer be obligated to purchase such
Product pursuant to this Agreement.

       8. Ordering. Each order by L-3 for STS Products (a "Purchase Order") will
specify the STS Products, the quantity, the appropriate specifications
corresponding to such STS Products (if necessary), 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 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. Orders by
L-3 for SIVAM Products shall be made in accordance with the SIVAM Proposals.

      9. Delivery.

            (a) All STS Products will be delivered freight paid F.O.B. (CMI's
(or its subsidiary's) plant).

            (b) L-3 reserves the right to inspect the STS Products and to
confirm the quantity of the STS Products within 30 days from the date of
delivery. Any claims for discrepant deliveries shall be reported by L-3 to CMI
in writing within such 30-day period. If L-3 fails to make such a claim within
the time specified, such order will be deemed accepted by L-3. Upon CMI
receiving notice from L-3 of such discrepancy, L-3 will have such remedies as
may be provided in the then-current standard terms and conditions of CMI.


                                      -4-

SIVAM Proposal.

      10. Raw and Packaging Materials. CMI will purchase and supply all raw
materials and packaging materials necessary for the manufacture of the STS
Products. CMI 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 STS Products.

      11. Terms of Sale. With respect to any Products or Services sold
hereunder, the selling party will invoice the other party at the time of
delivery or provision. Each invoice will be itemized in reasonable detail. The
non-selling party will pay to the selling party the amount of such invoice
within 60 days of the date of such invoice.

      12. 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 to keep such
information confidential; or (iv) is required to be disclosed by the Receiving
Party as a result of judicial or administrative process or by other requirements
of law.

      13. Indemnity.

            (a) With respect to any Products or Services sold hereunder, the
selling party agrees to indemnify and hold the other party and its affiliates
and their respective officers, directors, employees and agents, harmless from
and against any damages, liabilities, losses, expenses, (including, without
limitation, reasonable attorneys' fees) and amounts paid in settlement of any
claim, of any kind or nature whatsoever, which may be sustained or suffered as a
result of the infringement or alleged infringement of the copyrights or


                                      -5-
<PAGE>

U.S. patents of third parties or the breach by CMI of its represention in the
fourth sentence of Section 3.16 of the Purchase Agreement, and to defend, at its
expense, any actions, claims or suits against purchasing party based upon such
infringement or alleged infringement. If the use of any products furnished
hereunder is enjoined as a result of such a suit, the selling party at its
option, and at no expense to the other party, shall obtain for the other party
the right to use said products, substitute an equivalent product reasonably
acceptable to selling party and extend this indemnity thereto, or accept the
return of products and reimburse the other party the purchase price thereof,
less a charge for reasonable wear and tear. This indemnity does not extend to
any suit based upon any infringement or alleged infringement of any patent or
copyright to the extent due to the combination of any products furnished by the
selling party and other elements not supplied by or on behalf of the selling
party nor does it extend to any products to the extent such products infringe as
a result of the other party's design or formula.

            (b) The purchasing party agrees to notify the selling party in
writing of any suit. At its request and at its expense the selling party shall
have the right to control the defense of said suit. Except with the prior
written consent of the purchasing party, no selling party, in the defense of any
such claim or litigation, shall consent to entry of any judgment or enter into
any settlement that provides for injunctive or other nonmonetary relief
affecting the purchasing party or that does not include as an unconditional term
thereof the giving by each claimant or plaintiff to such purchasing party of a
release from all liability with respect to such claim or litigation. In the
event that the purchasing party shall in good faith determine that the conduct
of the defense of any claim subject to indemnification hereunder or any proposed
settlement of any such claim by the selling party might be expected to affect
adversely the purchasing party's tax liability or the ability of the purchasing
party to conduct its business, or that the purchasing party may have available
to it one or more defenses or counterclaims that are inconsistent with one or
more of those that may be available to the selling party in respect of such
claim or any litigation relating thereto, the purchasing party shall have the
right at all times to take over and assume control over the defense, settlement,
negotiations or litigation relating to any such claim at the sole cost of the
selling party, provided that if the purchasing party does so take over and
assume control, the purchasing party shall not settle such claim or litigation
without the written consent of the selling party, such consent not to be
unreasonably withheld. In the event that the selling party does not accept the
defense of any matter as above provided, the purchasing party shall have the
full right to defend against any such claim or demand and shall be entitled to
settle or agree to pay in full such claim or demand. In any event, the selling
party and the purchasing party shall cooperate in the defense of any claim or
litigation subject to this Section and the records of each shall be available to
the other with respect to such defense.

            (c) The foregoing Sections 13(a) and (b) state the entire liability
of the selling party for patent or copyright infringement. This Section will
survive the expiration or earlier termination of this Agreement.

      18. Export Control Compliance. Each party agrees to comply fully with the
United States Export Control Administration Regulations, the United States

insofar as they may control or limit the sale or use of Products or Services.
Each party also agrees to comply fully with the United States Foreign Corrupt
Practices Act.

      19. Force Majeure. Except for either party's payment obligations to the
other party for Products or Services 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 Products or
Services) shall be excused 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


                                      -7-
<PAGE>

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.

      20. Governing Law. This Agreement shall be governed in all respects,
including as to validity, interpretation and effect, by the internal laws of the

transferable by either party hereto without the prior written consent of the
other party, which consent will not be unreasonably withheld. This Agreement
