an attempt to make such a transfer without the authorization,  approval, consent
or waiver (collectively,  "Approval") of a third party would constitute a breach

products  delivered  to or by  Seller  or based  on any  obligations  under  the

that the  obligation  is imposed,  accrued,  asserted or incurred as a result of
acts or omissions of Seller,  or third  parties  whether or not acting on behalf
of, or  performing  any  function at the  request of Seller,  prior to or on the
Closing (collectively,  the "Liabilities").  Purchaser covenants and agrees with

                                 PURCHASE PRICE

                   Section 3.1 Consideration.  Upon the terms and subject to the
conditions  contained in this Agreement,  in consideration for the Assets and in
full payment therefore and the assumption of the Assumed Liabilities,  Purchaser
will pay, or cause to be paid, the purchase price set forth in Section 3.2.

                   Section  3.2  Purchase  Price.   Subject  to  the  terms  and
conditions of this Agreement (including, without limitation, adjustment pursuant
to Section 3.3 below),  as  consideration  for the Business and the Assets:  (a)
Purchaser  shall pay to Seller  Sixty-Two  Million  Dollars  ($62,000,000)  (the
"Purchase Price"); and (b) Purchaser shall assume the Assumed  Liabilities.  The
Purchase Price shall be paid as follows:

                         (i) Forty-Seven Million Dollars  ($47,000,000) shall be
paid in cash as of the Time of Closing (as defined in Section 6.1); and

                         (ii) Fifteen  Million  Dollars  ($15,000,000)  shall be
evidenced by an unsecured promissory note in the form attached hereto as Exhibit

                   Section 3.3 Purchase Price Adjustment.

                         (a) As used in this Section 3.3, the "Net Asset Amount"
of the Business of the Seller shall mean:  Inventory  plus  Accounts  Receivable
(less allowance for doubtful  accounts) plus Related  Property minus all Assumed
Liabilities.

                         (b) The Purchase Price shall be adjusted  downward only
on a dollar-  for-dollar  basis to reflect any difference  between the Net Asset
Amount  reflected on the unaudited  balance sheet of the Business as of December
31, 1997,  attached hereto as part of Schedule  4.1(c) (the  "Reference  Balance
Sheet") and the Net Asset Amount reflected on the unaudited balance sheet of the
Business  as at the  close of  business  on the date of the  Closing  (provided,
however,  that the Accounts  Receivable shall be measured as of the AR Closing),
which shall be prepared by Seller and its accountants from the books and records
of the  Business  in  accordance  with this  Agreement  and  generally  accepted
accounting  principles  ("GAAP")  and  applied  on a basis  consistent  with the
Reference  Balance Sheet (the "Closing Date Balance  Sheet")  (provided  that no
reduction in the value of the Related Property for the

                                       5.
<PAGE>

purpose  of  the  Closing  Date  Balance   Sheet  shall  be  made  for  ordinary
depreciation calculated in accordance with GAAP and past practice,  consistently
applied,  that would otherwise  accrue between December 31, 1997 and the Time of
Closing). In furtherance thereof,  Purchaser shall cooperate with Seller and its
accountants,  and shall provide such persons full access to the books,  records,
work papers, information,  facilities and employees of Purchaser relating to the
Business as conducted by  Purchaser  from and after the Time of Closing.  Seller
shall  deliver the Closing Date Balance  Sheet to Purchaser  within  twenty (20)
days following the Closing. Purchaser shall have sixty (60) days from receipt of
the  Closing  Date  Balance  Sheet in which to  notify  Seller  in detail of any
specific objections thereto,  during which period Seller shall provide Purchaser
and its accountants with reasonable access to Seller's and Seller's accountants'
working  papers used in preparing  the  Reference  Balance Sheet and the Closing
Date  Balance  Sheet.  If such  notice is given and the  parties  are  unable to
resolve their  disagreements  within ten (10) days following Seller's receipt of
such notice,  the matter in dispute shall be resolved by arbitration as provided
in Section 10.11 hereof.  Resolution of such dispute by agreement of the parties
hereto or by arbitration shall be final,  conclusive and binding on the parties.
If  applicable,  the Purchase  Price shall be adjusted  downward based upon such
final  resolution  (the  "Final  Adjustment").  Within  ten (10)  business  days
following the date of such final resolution,  Seller, if applicable, shall remit
in cash the amount of the difference by which the Net Asset Amount  reflected in
the Closing Date Balance Sheet is less than the Net Asset Amount as reflected in
the Reference Balance Sheet.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

                   Section 4.1 Representations and Warranties of Seller.  Except
as set forth in a letter (Schedule 4.1)  specifically  referring to this Section
4.1 of this Agreement (the "Disclosure Letter") delivered by Seller to Purchaser
and Brobeck,  Phleger & Harrison  LLP,  counsel to  Purchaser  and as updated by
Seller  prior to the Time of  Closing  (based  upon,  if  necessary,  an updated
Disclosure Letter and Schedules in a form reasonably  satisfactory to Purchaser)
(which Disclosure Letter contents themselves shall be deemed representations and
warranties of the Seller),  Seller hereby  represents  and warrants to Purchaser
that:

                   (a)  Organization  of Seller.  Seller is a  corporation  duly
organized and validly existing under the laws of the state of California and has
all requisite  power and authority to own and operate the Business in the places
where the Business is now conducted and to directly own, lease,  and operate the
Assets. Seller is duly qualified or licensed to do business as a corporation and
is in good  standing  in the  state of  California,  and is not  required  to be
qualified  in any other  jurisdiction  in which the  nature of its  business  or
location of its properties  requires such  qualification  or licensing and where
the  failure to be so  qualified  would have a  Material  Adverse  Effect on the
Business. There are no Subsidiaries,  joint ventures, or other arrangements that
conduct  any  aspect of the  Business  or that are used in or for the  Business.
"Material  Adverse  Effect," when used as a defined term in connection  with the
Business,  means any effect that is or could be deemed materially adverse to the
business, condition, results of operations, properties or assets of the Business
(excluding  the Excluded  Assets) as a whole;  provided,  however,  that (i) any
materially adverse effect that directly

                                       6.
<PAGE>

results from general worldwide  business,  economic or industry conditions shall
not be deemed to constitute,  and shall not be taken into account in determining
whether there has been or could be, a "Material Adverse Effect" on the Business,
and (ii) any materially  adverse effect that directly results from the taking of
any  action  explicitly  set  forth in this  Agreement  or the  announcement  or
pendency of the transactions  contemplated by this Agreement shall not be deemed
to constitute,  and shall not be taken into account in determining whether there
has been or could be, a "Material Adverse Effect" on the Business (excluding the
Excluded Assets). For purposes of this Agreement,  the term "Subsidiary" as to a
party  hereto  shall  mean any  corporation  or other  business  entity  that is
controlled,  directly or  indirectly,  by such party by the  ownership  of fifty
percent  (50%) or more of the  outstanding  voting stock (or other voting equity
interests) of the controlled corporation or other business entity.

                   (b)  Authorization  of  Seller.  Seller  has full  power  and
authority to enter into this Agreement to perform its obligations  hereunder and
to  consummate  the  transactions   contemplated  hereby,   including,   without
limitation,  the execution and delivery of this Agreement,  general conveyances,
bills of sale,  assignments,  and other documents and instruments evidencing the
conveyance of the Assets or delivered in  accordance  with Section 6.2 hereunder
(the "Closing Documents"). Seller has taken all necessary and appropriate action
with respect to the  execution  and delivery of this  Agreement  and the Closing
Documents.  This Agreement  constitutes valid and binding obligations of Seller,
enforceable  in  accordance  with its terms except as limited by (i)  applicable
bankruptcy,  insolvency,  moratorium,  reorganization,  or other laws  affecting
creditors' rights and remedies generally; and (ii) general principles of equity.

                   (c) Financial Information. Attached hereto as Schedule 4.1(c)
is a complete and accurate copy of Seller's (i) unaudited  balance sheets of the
Business  as of  December  31,  1997  and  December  31,  1996,  (ii)  unaudited
statements of operations of the Business for its fiscal years ended December 31,
1997, December 31, 1996 and December 31, 1995 and unaudited quarterly statements
of operations for the eight consecutive  quarters in fiscal years 1996 and 1997,
(iii) unaudited  statements of cash flows for the fiscal year ended December 31,
1997, and (iv) Business product sales and the average selling prices per product
breakdown for the eight  quarters in fiscal years 1996 and 1997 and for the full
fiscal  years 1996 and 1997 (which,  collectively  with the Closing Date Balance
Sheet referred to in Section 3.3(b) hereof,  shall be referred to herein for all
purposes as, the "Financial  Statements").  The Financial  Statements  have been
prepared in accordance with GAAP consistently  applied; the Financial Statements
fairly and accurately present the Assets and financial  position,  product sales
and average selling prices of the Business of Seller as and at the dates thereof
and  Seller's  results of  operations  for the  Business  and cash flows for the
Business for the periods then ended,  except for year-end  adjustments  which in
the  aggregate  have not been material to the condition or results of operations
of the Business and for the absence of notes thereto.  The projections of Seller
as they relate to the  Business and as provided to  Purchaser  were  prepared in
good faith and are based on  reasonable  assumptions.  All of  Seller's  general
ledgers, books and records are located at Seller's Business Premises.

                   (d)     [Intentionally omitted].

of the Assets or impair the  operations  conducted  thereon or any  discharge or
satisfaction thereof;

                         (vi)  Any  sale,  lease,  or  disposition  of,  or  any
agreement  to sell,  lease,  or dispose of any of the Assets,  other than sales,
leases,  or  dispositions  in the usual and  ordinary  course  of  business  and
consistent with prior practice;

                         (vii)  Any  material   modification,   waiver,  change,
amendment,  release, rescission,  accord and satisfaction, or termination of, or
with respect to, any term, condition,  or provision of any contract,  agreement,

has terminated,  or intends to terminate, such employee's employment with Seller
where such  termination  would or could have a  Material  Adverse  Effect on the

31, 1997.  Seller has attached to the  Disclosure  Letter  complete and accurate
copies or  descriptions  of all current  agreements  (written or unwritten) with
such customers. Seller is not aware of any event, happening, or fact which would

or fact  which  would  lead it to believe  that any of such  Suppliers  will not
continue to supply the current level and type of goods  currently being provided
to Seller on similar terms and conditions.

                                       16.

                   (ad)  Books and  Records.  The books  and  records  of Seller
related to the Business to which  Purchaser  and its  accountants  and attorneys
have been given  access are the true books and records of Seller  related to the
Business and truly and fairly reflect the underlying  facts and  transactions in
all material respects.

                   (ae) Complete Disclosure.  No representation or warranty made
by Seller in this Agreement, nor any document,  written information,  statement,
financial statement,  certificate, schedule or exhibit prepared and furnished or
to be prepared and furnished by Seller or its  representatives  pursuant  hereto
contains  or will  contain  any  untrue  statement  of a material  fact,  or, to
Seller's  knowledge,  omits or will omit to state a material  fact  necessary to
make the statements or facts contained herein or therein not misleading in light
of the circumstances under which they were furnished. All schedules and exhibits
prepared  by  Seller  shall  be  updated  as of the  Time of  Closing  in a form
satisfactory to Purchaser.

                   (af)  Proprietary  Agreements.  All technical and  management
personnel, including consultants, employed by Seller relating to the Business or
used by the Business,  have executed  agreements  regarding  confidentiality and
proprietary  information.   Each  employee-inventor  has  validly  and  properly
assigned  his or her  rights to the  Seller on all  inventions,  pending  patent
applications  and all patents  issued.  To the extent the Seller has  previously
utilized consultants or independent contractors,  each consultant or independent
contractor has validly and properly  assigned to the Seller his or her rights in
and to all  copyrights  and works of  authorship  relating  to the Assets or the
Business.  The Seller has no knowledge that any of its service  providers in the
Business are in violation thereof and will use reasonable efforts to prevent any
such violation. The Seller has no knowledge that any of its service providers in
the Business is obligated under any contract (including  licenses,  covenants or
commitments  of any  nature) or other  agreement,  or  subject to any  judgment,
decree or order of any court or administrative  agency,  that would interfere in
any  material  respect  with the use of his or her best  efforts to promote  the
interests of the Seller in the Business or that would conflict with the Business
as  conducted  or as proposed  to be  conducted  or that would  prevent any such
service provider from assigning inventions included in the Assets to the Seller.
The Seller has no knowledge  that the Assets will include any  inventions of any
of its service  providers (or people it currently intends to hire) made prior to
employment by the Seller or relationship with the Business or Seller.

                   (ag) Absence of Governmental or Other Objection.  There is no
pending or threatened  lawsuit or action or hearing  challenging the transaction
by any body or agency of the foreign,  federal,  state or local government or by
any third party,  and the  consummation of the transaction has not been enjoined
by a court of competent jurisdiction.  There is no legislation and no rulings in
effect by the  Federal  Communications  Commission  or any  other  governmental,
regulatory  or  administrative  body or agency  that  would  make  operation  of
Seller's radio systems inoperable in any jurisdiction.

                   (ah) Insurance. Schedule 4.1(ah) lists all insurance policies
and  fidelity  bonds  covering  the  assets,  business,  equipment,  properties,
operations, employees, officers and directors of Seller, the amounts of coverage
under  each such  policy and bond of Seller.  Seller  has not been  refused  any
requested coverage and no material claim made by Seller related to

                                       17.
<PAGE>

the Business has been denied by the  underwriters of such policies or bonds. All
premiums payable under all such policies and bonds have been paid, and Seller is
otherwise in full compliance with the terms of such policies and bonds (or other
policies and bonds providing  substantially  similar insurance  coverage).  Such
policies  of  insurance  and  bonds are of the type and in  amounts  customarily
carried by persons conducting businesses similar to those of Seller. Seller does
not know of any threatened  termination of, the  invalidation of any coverage of
or material premium increase with respect to, any of such policies.

                   (ai) Environmental Matters.

                           (i) Seller has all permits,  licenses,  approvals and
registrations  required  to  be  issued  with  respect  to  the  Business  under
applicable federal,  state and local laws, statutes, and regulations relating to
the protection of human health,  safety,  the environment and natural  resources
("Environmental  Laws")  and is in  compliance  with the  terms  and  conditions
thereunder, other than those permits, licenses, approvals and registrations, the
absence of which would not have a Material Adverse Effect on the Business.

                           (ii)  Schedule  4.1(ai)  sets forth all  arrangements
that Seller  currently  has in effect or in the five-year  period  preceding the
Time of Closing has had in effect for the  removal,  disposal,  release,  and/or
processing  of  hazardous  substances  or  hazardous  waste with  respect to the
Business.  For  purposes of this  Agreement,  the terms  "disposal,"  "release,"
"hazardous  substance" and "hazardous waste" shall have the definitions assigned
thereto under federal, state, and local laws applicable to Seller, the Business,
the  assets of Seller,  or the  property  owned or leased by  Seller,  including
without limitation the Comprehensive Environmental Response,  Compensation,  and
Liability  Act of  1980,  42  U.S.C.  ss.9601  et  seq.,  as  amended,  and  any
regulations   promulgated  thereto,   except  that  "hazardous   substance"  and
"hazardous waste" shall include all varieties of petroleum hydrocarbons, refined
or unrefined.

                           (iii) Within the last five years, Seller has not been
alleged to be in material  violation of, or been subject to any  administrative,
judicial,  or  regulatory  proceeding  pursuant  to, any  Environmental  Laws or
regulations.  No Claims  (as  hereinafter  defined)  have been or are  currently
asserted against Seller with respect to hazardous substances or hazardous wastes
with respect to the  Business.  As used herein,  "Claim"  shall mean any and all
claims, demands,  orders, causes of action, suits,  proceedings,  administrative
proceedings, judgments, decrees, damages, costs and reasonable attorneys' fees.

                           (iv) No officers or managers of Seller have  received
any notice within the five-year  period preceding the Time of Closing that there
has been any unauthorized treatment,  storage,  disposal,  release or threatened
release  from any  off-site  treatment,  storage  or  disposal  facility  of any
hazardous  substance or  hazardous  waste  originating  from,  or generated  by,
Seller.

                   (aj) Backlog.  Schedule 4.1(aj) hereto sets forth the backlog
of orders  relating to the Business  that Seller is to ship and contract work to
be  performed  as  of  the  Time  of  Closing,  provided  that  no  warranty  or
representation  is made pursuant to this Section 4.1(aj) that any order included
in such backlog is not cancelable, modifiable or subject to

                                       18.
                   
<PAGE>

delay in shipping by the other party thereto. Seller either possesses sufficient
inventory  of parts,  materials  and  personnel to produce the same within their
scheduled  delivery  dates or such parts or materials  have lead times such that
Seller can  acquire  such parts and  materials  in time to produce and ship such
backlog in accordance with its scheduled shipping date.

                   (ak) Accounts Receivable.  To Seller's knowledge,  the amount
of all Accounts Receivable purchased by Purchaser will be collectible in full in
the ordinary  course of business on or before  December  31, 1998;  all Accounts
Receivable arise from bona fide transactions in the ordinary course of business;
no contest or questions  with respect to the amount or validity of any amount is
pending;  and none of such  Accounts  Receivable  is or will at the  Closing  be
subject to any  counterclaim,  dispute or  setoff.  The value at which  Accounts
Receivable  are carried  reflect the  accounts  receivable  valuation  policy of
Seller.  As of December 31, 1997 and as of the  Closing,  except as set forth in
Schedule  1.1(f),  there  is  and  will  be (i) no  Accounts  Receivable  debtor
delinquent  in its  payment  by more than  thirty  (30) days,  (ii) no  Accounts
Receivable  debtor  that  has  refused  (or  threatened  to  refuse)  to pay its
obligation for any reason,  (iii) to Seller's knowledge,  no Accounts Receivable
debtor that is insolvent or bankrupt,  and (iv) no Account  Receivable  which is
pledged to any third party by Seller.  Seller holds no deposits  from  customers
and has received no prepaid service  contract  revenue or other prepaid revenue.
Notwithstanding  any representation or warranty set forth in Section 4.1 of this
Agreement  to the  contrary,  other  than  the  representations  and  warranties
included in this paragraph 4.1(ak),  Seller makes no representations or warranty
regarding its Accounts Receivable and rights therein.

                   (al)  Exports  to  Certain  Countries.  For  the  five  years
preceding  the date  hereof,  Seller  has made no sales to  entities  located or
residing or domiciled in,  directly or  indirectly,  Cuba,  North Korea,  Libya,
Iraq, Iran or any other countries prohibited by U.S.
export control laws.

                   (am) Foreign Corrupt Practices Act. None of the activities or
types of conduct  below have been or may have been engaged in by Seller,  either
directly or, to Seller's knowledge, indirectly:

                                  (i) Any  bribes  or  kickbacks  to  government
officials or their relatives, or any other payments to such persons,  whether or
not legal, to obtain or retain business or to receive  favorable  treatment with
regard to business; or

                                  (ii) Any bribes or kickbacks to persons  other
than  government  officials,  or to  relatives  of such  persons,  or any  other
payments to such persons or their relatives,  whether or not legal, to obtain or
retain business or to receive favorable treatment with regard to business; or

                                  (iii) Any  illegal  contributions  made to any
political party, political candidate or holder of governmental office; or


                                       19.
                                  
<PAGE>

                                  (iv)  Any  bank  accounts,  funds  or pools of
funds created or maintained  without being  reflected on the corporate  books of
account,  or as to which the receipts and disbursements  therefrom have not been
reflected on such books; or

                                  (v) Any receipts or disbursements,  the actual
nature  of which  has  been  "disguised"  or  intentionally  misrecorded  on the
corporate books of account; or

                                  (vi) Fees paid to  consultants  or  commercial
agents which  exceeded the  reasonable  value of the services  purported to have
been rendered; or

                                  (vii) Any payments or  reimbursements  made to
personnel of Seller for the purposes of enabling  them to expend time or to make
contributions  or  payments  of the  kind  or for  the  purpose  referred  to in
subparagraphs  (i)-(vi) above.  In addition,  Seller has not violated the United
States Foreign Corrupt Practices Act or any other similar laws, statute, rule or
regulation of any country.

                   Section 4.2  Representations  and  Warranties  of  Purchaser.
Purchaser hereby represents and warrants that:

                   (a)  Organization.  Purchaser is a corporation duly organized
and  validly  existing  under  the laws of the  State of  Delaware,  and has all
corporate  power and  authority to lease,  own, and operate its  properties  and
carry on its business and operations and to directly own, lease, and operate the
assets of Purchaser. Purchaser is duly qualified or licensed to do business as a
corporation,  and is in good standing in each jurisdiction  where the failure to
qualify  would have a material  adverse  effect on its business and  operations.
Purchaser  has made  available to Seller  complete  and  accurate  copies of its
Certificate of Incorporation and Bylaws and all amendments thereto,  and minutes
and actions of all of its Board of Directors and its stockholders.  No corporate
actions  have been  approved or taken by  Purchaser's  Board of Directors or the
stockholders that are not reflected in such minutes and actions.

                   (b) Authorization of Purchaser.  Purchaser has full power and
authority to enter into this Agreement,  to perform its  obligations  hereunder,
and to consummate  the  transactions  contemplated  hereby,  including,  without
limitation, the execution and delivery of this Agreement and the other documents
and  instruments  evidencing  the  conveyance  of the  Assets  or  delivered  in
accordance with Section 6.3 hereunder ("Purchaser Closing Documents"). Purchaser
has taken all necessary and appropriate action with respect to the execution and
delivery of this Agreement and the Purchaser Closing  Documents.  This Agreement
constitutes  valid  and  binding   obligations  of  Purchaser,   enforceable  in
accordance  with  its  terms,  except  as  limited  by  applicable   bankruptcy,
insolvency,  moratorium,  reorganization,  or other  laws  affecting  creditors'
rights and remedies generally and general principles of equity.

                   (c) No  Conflict or Default.  Neither the  execution  of this
Agreement or any of the Closing Documents, nor the performance hereof or thereof
by Purchaser will: (i) conflict with or result in the breach or violation of the
terms of any material decree, judgment, order, law or regulation of any court or
other governmental body now in effect

                                       20.
      
<PAGE>

applicable to Purchaser;  (ii) conflict  with, or result in, with or without the
passage  of time or the  giving of  notice,  any  breach of any of the  material
terms, conditions and provisions of, or constitute a default under, any material
indenture,  mortgage, lease, agreement or other instrument to which Purchaser is
a party  or by  which  it is  bound;  or  (iii)  violate  or  conflict  with any
provisions of Purchaser's Certificate of Incorporation or Bylaws.

                   (d) Consents.  Except as required pursuant to the HSR Act, no
consent from any third party and no consent,  approval or  authorization  of, or
declaration,  filing  or  registration  with,  any  governmental  or  regulatory
authority is required to be made or obtained by Purchaser in order to permit the
execution,  delivery or  performance  of this  Agreement  by  Purchaser,  or the
consummation  by Purchaser of its  obligations  contemplated  by this Agreement,
except for such  consents  where the failure to obtain the same would not have a
Material  Adverse  Effect on the  business,  results of  operations or financial
condition of Purchaser taken as a whole.

                   (e)  Sufficient  Funds.  Purchaser  will  have at the Time of
Closing  sufficient funds available to pay the Purchase Price.  Purchaser is not
insolvent, and payment of the Purchase Price and, to the knowledge of Purchaser,
assumption of the Assumed Liabilities will not cause it to become insolvent.

                                    ARTICLE V

                                    COVENANTS

                   Section 5.1 Covenants Against  Disclosure.  The parties agree
to maintain the  confidentiality  of the terms and conditions of this Agreement,
except to the  extent  required  by law and  pursuant  to the  public  reporting
obligations of Purchaser and Seller. No party shall  disseminate  (except to the
parties to this  Agreement)  any press release or  announcement  concerning  the
transactions  contemplated  by this  Agreement or the parties hereto without the
prior  consent  of Seller and  Purchaser,  except as  required  under the public
reporting  obligations  of Purchaser  and Seller or as may be required to obtain
consents necessary pursuant to Sections 7.1(d), (e) and (i) hereof to consummate
the transactions contemplated herein.

                   Section 5.2 Reciprocal Immunity Licenses.

                           (a)  Effective  as of the  Time  of  Closing,  Seller
grants to  Purchaser a  non-exclusive,  non-transferable  and  non-sublicensable
(each subject to Section 5.2(c) below), perpetual, world-wide,  fully-paid right
and license under the Retained  Intellectual Property Rights to use the Retained
Intellectual  Property  Rights (as the same  exists at the Time of  Closing)  to
make, have made, use and sell products (or any systems, subsystems or components
thereof) within the Business Field of Use (as defined below) that incorporate or
are  developed or made using the Retained  Intellectual  Property  Rights.  Such
license  shall not give  Purchaser  any right to have  delivered,  have physical
access to or  receive  any  portion  of the  proprietary  information  of Seller
related to the Retained Intellectual Property Rights, and is limited to Seller's
covenant not to make claims or assert any cause of action against

                                       21.
                           
<PAGE>

Purchaser  (or any  subsidiary,  spinout or joint  venture of  Purchaser) or any
customers  of  Purchaser  (or  any  subsidiary,  spinout  or  joint  venture  of
Purchaser)  for  infringement,  misappropriation  or  unauthorized  use  of  the
Retained Intellectual Property Rights arising as a result of Purchaser's (or any
subsidiary's,  spinout's or joint  ventures'  of  Purchaser)  or any  customer's
exercise  of the  non-exclusive  license  rights  set  forth  in  the  foregoing
sentence.  Notwithstanding  any term or condition of this Section 5.2, Purchaser
shall have no  license  rights to any trade  name,  trademark  or  service  mark
included in the  Retained  Intellectual  Property  Rights.  For purposes of this
Agreement,  the term  "Business  Field of Use"  shall mean and be limited to the
development, manufacture, distribution, marketing, sale and use of radio systems
or  subsystems  or  components   thereof  used  for  wireless   transmission  of
communications.

                           (b)  Effective  as of the Time of Closing,  Purchaser
grants   to   Seller   a   personal,    non-exclusive,    non-transferable   and
non-sublicensable  (subject to Section  5.2(c)  below),  perpetual,  world-wide,
fully-paid  right and license to use the  Intellectual  Property  Rights (as the
same exists at the Time of Closing) to make,  have made,  use and sell  products
(or any subsystems or components thereof) (other than radio systems,  subsystems
or  components)  solely within the Retained Field of Use (as defined below) that
incorporate  or are developed or made using the  Intellectual  Property  Rights.
Such licenses shall not give Seller any right to have  delivered,  have physical
access or  receive  any  portion of the  proprietary  information  of  Purchaser
related to the Intellectual  Property Rights,  and is conditioned on Purchaser's
covenant  not to make  claims or assert  any cause of action  against  Seller or
Seller's customers for infringement, misappropriation or unauthorized use of the
Intellectual  Property  Rights  arising as a result of Seller's  exercise of the
non-exclusive  license rights set forth in the foregoing sentence.  For purposes
of this  Agreement,  "Retained  Field of Use"  shall  mean and be limited to the
manufacture,  sale and use of products (other than radio systems,  subsystems or
components) in the information security and encryption business. Notwithstanding
the foregoing,  Seller shall have no right or access to any of  Purchaser's  (or
any  subsidiary's,  spinout's  or joint  ventures'  of  Purchaser)  intellectual
property developed by Purchaser (or any subsidiary, spinout or joint ventures of
Purchaser) prior to or after the Time of Closing.

                           (c) Notwithstanding the foregoing,  each of Purchaser
and Seller shall have no right or access to any intellectual  property developed
by the other  party or any of its  Subsidiaries  after the Time of  Closing  and
Purchaser  shall be entitled to transfer and  sublicense  such license rights to
any of its  subsidiaries,  joint  ventures or spinouts.  Any  transferee  of the
rights set forth in Section  5.2(a)  above shall agree in writing to be bound to
all relevant terms and conditions of this Agreement as a condition  precedent to
such transfer.

                   Section 5.3      Non-Competition.

                           5.3.1   Commencing   on  the  Time  of  Closing   and
continuing  for  three  (3)  years  thereafter,  Seller  agrees  that it and its
Subsidiaries  and  affiliates  controlled by or under common control with Seller
shall not  engage,  directly or  indirectly,  whether on its own account or as a
shareholder (other than as a less than 10% shareholder of a publicly-held

                                       22.

company), partner, joint venturer, employee, consultant,  advisor, and/or agent,
of  any  person,  firm,  corporation,  or  other  entity,  in  any or all of the
following activities worldwide:

                           (a) Enter into or engage in the Business;

                           (b) Encourage or solicit any former  employees of the
Seller or its  Subsidiaries  who became  employees  of  Purchaser  or any of its
affiliates at the Time of Closing to leave the employment of Purchaser or any of
its affiliates for any reason; or

                           (c) Promote or assist,  financially or otherwise, any
person, firm, association, corporation, or other entity engaged in the Business;

                           5.3.2  Without  limitation,  the  parties  agree  and
intend that the covenants  contained in this Section 5.3 shall be deemed to be a
series of separate  covenants and  agreements,  one for each and every county of
each state and political subdivision worldwide.  If, in any judicial proceeding,
a court  shall  refuse to enforce in such action any of the  separate  covenants
deemed included  herein,  then at the option of Purchaser,  wholly-unenforceable
covenants shall be deemed  eliminated from the provisions hereof for the purpose
of such  proceeding  to the extent  necessary to permit the  remaining  separate
covenants to be enforced in such a proceeding.

                           5.3.3 The parties agree that due to the unique nature
of the services and  capabilities of Seller,  there can be no adequate remedy at
law for any  breach of their  obligations  hereunder,  that any such  breach may
allow Seller and/or third parties to unfairly  compete with  Purchaser or any of
its affiliates resulting in irreparable harm to Purchaser or such affiliate, and
therefore,  that upon any such breach or any threat thereof,  Purchaser shall be
entitled to seek appropriate  equitable relief in addition to whatever  remedies
it might have at law. Further, Purchaser shall be entitled to indemnification by
Seller from any loss or harm, including, without limitation, attorney's fees, in
connection  with  any  breach,  or  any  enforcement,  of  Seller's  obligations
hereunder.

                           5.3.4  Seller  represents  and  warrants to Purchaser
that the  covenants of Seller in this Section 5.3 are  reasonably  necessary for
the protection of Purchaser's  interests under this Agreement and are not unduly
restrictive upon Seller.

                           5.3.5 Notwithstanding the foregoing,  nothing in this
Section 5.3 shall be deemed to prevent a direct or indirect acquisition,  merger
or  consolidation   (collectively,   for  purposes  of  this  Section  5.3.5  an
"acquisition")  of Seller  and/or  its  Subsidiaries  which  effects a change of
control of at least a majority of the voting stock of Seller or a sale, transfer
or  license  of all or  substantially  all of the  assets of Seller  and/or  its
Subsidiaries,  by,  with or into  another  company  or  business  engaged in the
Business,  and the ability of that company or business to engage in the Business
following  such  acquisition,   merger  or  consolidation;   provided  that  the
resources,  operations,   management  and  other  employees  of  Seller  do  not
participate, directly or indirectly, in the Business.


                                       23.

                           5.3.6 The foregoing  restrictions in this Section 5.3
shall not limit  Seller  in any  respect  from  manufacturing,  selling,  using,
licensing  or otherwise  making  available  any  information  security  products
(excluding  radio systems,  subsystems and components) to any party,  including,
without limitation, a party engaged in the Business.

                   Section 5.4  Maintenance of Business.  During the period from
the date of this Agreement and continuing  until the earlier of the  termination
of this Agreement or the AR Time of Closing,  except to the extent  contemplated
by this  Agreement  or as  requested  by  Purchaser,  Seller  shall carry on the
Business in the usual,  regular and ordinary  course in  substantially  the same
manner as  conducted  prior to the date of this  Agreement  and,  to the  extent
consistent  with such  Business,  use its best  efforts to  preserve  intact its
present  business  organizations,  keep  available  the  services of its present
service  providers and preserve its  relationships  with  customers,  suppliers,
distributors, licensors, licensees, and others having business dealings with it,
to the end that its  goodwill  and ongoing  businesses  related to the  Business
shall be  unimpaired  at the AR Time of Closing.  Seller shall  promptly  notify
Purchaser of any event or  occurrence  not in the  ordinary  course and relating
directly  or  indirectly  to the  Business,  and any event  which  could  have a
material  adverse effect on the condition,  business or results of operations of
the Business.

                   Section 5.5 Access to Information. Seller will give Purchaser

its  affiliates  for periods  ending on or prior to the Closing and for portions
through the Closing of periods  beginning  prior to the Closing and ending after
the Closing (including,  without limitation, any deferred Tax liability, any Tax
liability  arising from the  transactions  contemplated in this Agreement or any
other transaction entered into or consummated prior to the Closing),  including,
without limitation, any liability arising out of or related to any returns filed
prior to the Time of Closing;

                                   (v) Any  Liabilities  of Seller  imposed upon
Purchaser  as  transferee  of  the  Assets  or  otherwise,   including,  without
limitation,  any  liability  arising out of any lien or any  obligation or claim
brought by  creditors  of Seller or claims based on the premise that the sale of
the Assets  did not comply  with any bulk  sales  provisions  and any  liability
arising out of obligations to Seller's employees (including, without limitation,
any  obligations  under any  employee  benefit,  profit  sharing,  or pension or
welfare plan) or out of Seller's status as employer of its employees;

                                   (vi) Any amounts paid or payable by Purchaser
after the Time of Closing with respect to any Liabilities of Seller,  which have
not  been  paid in full by  Seller  following  twenty  (20)  days'  notice  from
Purchaser to Seller of the existence of such Liability and Purchaser's intention
to pay in full such Liability on behalf of Seller; and

                         (b)  Purchaser  hereby  agrees  to  indemnify  and hold
harmless Seller and its officers, directors and other affiliates against any and
all  Damages  asserted  against,  resulting  from,  imposed  upon or incurred or
suffered by Seller,  directly or indirectly,  as a result of or arising from (1)
any  inaccuracy in or breach or  nonfulfillment  of any of the  representations,
warranties,  covenants or agreements  made by Purchaser in this Agreement or any
facts or circumstances constituting such an inaccuracy, breach or nonfulfillment
provided Seller is or has not been in breach hereof,  (2) any Assumed Liability,
(3) Purchaser's hiring and employment  practices with respect to employment with
Purchaser of, or termination of employment with Purchaser of, Seller's employees
to be offered  employment  or hired by Purchaser,  provided  Seller has complied
with and is not in breach of its related representations,  warranties, covenants
and obligations  pursuant  hereto or (4)  Purchaser's  operation of the Business
from and after the Time of Closing, provided Seller has complied

                                       32.

with and is not in breach of its related representations,  warranties, covenants
and obligations pursuant hereto (all of which shall be referred to as "Purchaser
Identifiable Claims").

                         (c) Without limiting the foregoing, any amounts paid or
payable by Purchaser  pursuant to this Agreement  shall be subject to a right of
setoff by Purchaser or its affiliates  for any Damages  incurred by Purchaser or
its officers,  directors or other  affiliates in connection with this Agreement;
provided,  however, that payments due under the Note shall not be subject to any
right of offset.

                   Section 8.3  Procedure  for  Indemnification  with Respect to
Third-Party Claims.

                         (a) If the  Purchaser or any  affiliate of Purchaser or
Seller or any of Seller's  Subsidiaries and each of their  respective  officers,
directors, shareholders,  employees, agents and other affiliates, as applicable,
determines to seek indemnification (such party shall be referred to herein as an
"Indemnified Party") under this Article VIII with respect to Seller Identifiable
Claims or Purchaser  Identifiable  Claims,  as applicable  (such Claims shall be
referred to herein as  "Identifiable  Claims"),  resulting from the assertion of
liability  by third  parties,  such  Indemnified  Party shall give notice to the
parties from which  indemnification is sought (such parties shall be referred to
herein  as  "Indemnifying  Parties")  within 90 days of such  Indemnified  Party
becoming  aware of any such  Identifiable  Claim or of facts upon which any such
Identifiable  Claim  will be based;  the notice  shall set forth  such  material
information  with  respect  thereto  as is  then  reasonably  available  to such
Indemnified   Party.  In  case  any  such  liability  is  asserted  against  any
Indemnified Party, and such Indemnified Party notifies the Indemnifying  Parties
thereof, the Indemnifying Parties will be entitled, if such Indemnifying Parties
so elect by written notice  delivered to such  Indemnified  Party within 20 days
after receiving such Indemnified  Party's notice,  to assume the defense thereof
with  counsel  selected  by the  Indemnifying  Party,  which  counsel  shall  be
reasonably satisfactory to such Indemnified Party. In the event the Indemnifying
Party assumes the defense,  the Indemnifying  Party shall have sole control over
the management of the defense.  Notwithstanding  the foregoing,  (i) none of the
Indemnified  Parties  shall  have  any  obligation  to give  any  notice  of any
assertion of liability by a third party unless such assertion is in writing, and
(ii) the  rights of the  Indemnified  Parties  to be  indemnified  hereunder  in
respect of  Identifiable  Claims  resulting  from the  assertion of liability by
third  parties  shall not be adversely  affected by their failure to give notice
pursuant to the  foregoing  unless,  and, if so, only to the extent  that,  such
Indemnifying  Parties are  materially  prejudiced  thereby.  With respect to any
assertion of liability by a third party that results in an  Identifiable  Claim,
the parties hereto shall make  available to each other all relevant  information
in their possession material to any such assertion.

                         (b) In the event that such Indemnifying Parties, within
20 days after receipt of the aforesaid notice of an Identifiable  Claim, fail to
assume the defense of such Indemnified  Party against such  Identifiable  Claim,
such  Indemnified   Party  shall  have  the  right  to  undertake  the  defense,
compromise,  or  settlement  of such  action on  behalf of and for the  account,
expense, and risk of such Indemnifying Parties.


                                       33.
<PAGE>

                         (c)  Notwithstanding  anything in this  Article VIII to
the  contrary,  (i) if there is a reasonable  probability  that an  Identifiable
Claim may materially  adversely affect such Indemnified  Party, such Indemnified
Party  shall  have the right to  participate  in such  defense,  compromise,  or
settlement and such  Indemnifying  Parties shall not,  without such  Indemnified
Party's  written  consent  (which consent shall not be  unreasonably  withheld),
settle or compromise any Identifiable  Claim or consent to entry of any judgment
in respect thereof unless such settlement, compromise, or consent includes as an
unconditional  term thereof the giving by the claimant or the  plaintiff to such
Indemnified  Party a release from all liability in respect of such  Identifiable
Claim.

                   Section 8.4  Procedure  For  Indemnification  with Respect to
Non-Third  Party  Claims.  In the event that any  Indemnified  Party asserts the
existence of a claim giving rise to Damages (but excluding claims resulting from
the assertion of liability by third  parties),  it shall give written  notice to
the Indemnifying Parties. Such written notice shall state that it is being given
pursuant  to this  Section  8.4,  specify  the  nature  and  amount of the claim
asserted and indicate the date on which such assertion  shall be deemed accepted
and the amount of the claim deemed a valid claim (such date to be established in
accordance with the next sentence). If such Indemnifying Parties, within 90 days
after the mailing of notice by such  Indemnified  Party,  shall not give written
notice to such Indemnified Party announcing its intent to contest such assertion
of such  Indemnified  Party,  such  assertion  shall be deemed  accepted and the
amount of claim shall be deemed a valid claim. In the event,  however, that such
Indemnifying  Parties  contest the  assertion  of a claim by giving such written
notice to such Indemnified Party within said period,  then the parties shall act
in good faith to reach  agreement  regarding such claim.  If the parties hereto,
acting in good faith,  cannot reach  agreement with respect to such claim within
ten (10) days after notice thereof,  such claim will be submitted to and settled
by arbitration pursuant to Section 10.11 hereof.

                   Section 8.5 Limitations on Indemnification.

                         (a)  No  claim  or  claims  may  be  made   against  an
Indemnifying  Party for  indemnification  pursuant to Section 8.2 or pursuant to
Section  8.6 or 8.7  hereof,  unless the  aggregate  Damages of the  Indemnified
Parties with respect to such Section  shall exceed an aggregate  amount equal to
$250,000,  in which  case the  Indemnifying  Party  shall  be  obligated  to the
indemnified party for the amount in excess of such $250,000 threshold amount.

                         (b) In  addition,  the  liability  of any  Indemnifying
Party with respect to any Damages  shall be determined on a basis that is net of
the amount of any such Damages  covered by insurance  (less any  deductibles  or
increased premiums) and net of the tax benefit received by the Indemnified Party
due to  deductibility  of such Damages on its Federal and state corporate income
tax returns.

                   Section  8.6  Specified  and  Current  Product   Intellectual
Property.  Without giving effect to any of the disclosures or qualifications set
forth in this Agreement, any accompanying schedule, exhibit or certificate,  and
subject to Sections 8.1, 8.3, 8.4 and 8.5 hereof, Seller covenants and agrees to
indemnify and hold harmless, without giving effect to any limitations in Section
8.5, the Purchaser and each of its officers, directors and other

                                       34.

affiliates  for  all  of  the  "Specified   Intellectual  Property  Damages"  in
perpetuity and for any "Current Product Intellectual Property Damages" for which
a claim is made pursuant to Section 8.7 below prior to three (3) years after the
Time of Closing. As used herein, "Specified Intellectual Property Damages" shall
include all Damages (whether incurred,  accrued, asserted or alleged prior to or
after the date of this  Agreement)  suffered or incurred by  Purchaser or any of
its officers,  directors or other affiliates with respect to any and all claims,
demands, settlements, criminal investigations, liabilities, injunctions, actions
and  causes of action  which  arise out of (or have  arisen out of) or relate to
claims or facts or circumstances  or allegations  existing prior to or following
the Closing  (whenever  asserted  or made known to the  parties  hereto) for the
design,  development,  manufacture,  marketing,  license, sale or use of the (i)
"Slurpie"  products,  (ii) the  products of Seller  relating to the  Business as
being  produced as of the Time of Closing,  (iii)  products of the Business that
were  produced  prior  to the Time of  Closing  and  (iv)  improvements  to such
products,  modifications  or  derivatives  to  such  products  or  new  or  next
generation  products  manufactured,  designed or  developed  by Purchaser or its
Subsidiaries,  provided that for purposes of clause (iv) hereof,  the underlying
claims or facts or  circumstances  or allegations of  infringement  are based on
designs or  implementations  utilized in the products in existence  prior to the
Time of Closing,  ("S.I.P.  Covered  Products",  and collectively with the "CPIP
Covered Products" the "Covered Products") which directly or indirectly arise out
of any  claims of  intellectual  property  infringement  as to  patents or other
intellectual  property set forth in the Disclosure  Letter and related Schedules
or patents or other  intellectual  property  of which  Seller had  knowledge  or
written  notice  prior  to the  Closing  and  which  are  not set  forth  in the
Disclosure  Letter and related  Schedules  (collectively,  the  "S.I.P.  Covered
Claims").

                   As  used  herein,   "Current  Product  Intellectual  Property
Damages"  shall  include all Damages  (whether  incurred,  accrued,  asserted or
alleged  prior to or after the date of this  Agreement)  against or  suffered or
incurred by Purchaser or any of its officers, directors or other affiliates with
respect to any and all claims, demands,  settlements,  criminal  investigations,
liabilities, actions and causes of action which directly or indirectly arise out
of (or have  arisen  out of) or relate to  claims or facts or  circumstances  or
allegations  existing  prior to or during  the three  (3)  years  following  the
Closing (subject to Section 8.1 hereof,  whenever  asserted or made known to the
parties hereto) involving any and all intellectual  property matters relating to
the products of Seller  relating to the Business as are being produced as of the
Time of Closing or  products  that were  produced  prior to the Time of Closing,
including  the   "Slurpie"   enhancements   (exclusive   of  any   improvements,
modifications  or  enhancements to such products after the Time of Closing) (the
"CPIP  Covered   Products")   to  the  extent  that  the  design,   development,
manufacture,  marketing,  license,  sale  or use of the  CPIP  Covered  Products
infringes any copyright,  patent,  trade secret, or other intellectual  property
right of any third party that exists at the Time of Closing  (or, in the case of
patents, were granted, or to Seller's knowledge,  applied for, no later then the
Time of Closing) or violates any license or agreement  with any third party (the
"C.P.I.P. Covered Claims").

                   Section 8.7 Defense of Covered  Claims for the  Specified and
Current Product  Intellectual  Property Damages.  Purchaser shall give notice to
Seller promptly within 90 days of receipt of actual written notice of any S.I.P.
or C.P.I.P.  Covered  Claim  (collectively,  the  "Covered  Claims") as to which
indemnity may be sought, and shall permit

                                       35.
<PAGE>

Seller to assume  the  defense  of any such  claim or any  litigation  resulting
therefrom,  provided  that counsel for Seller,  who shall conduct the defense of
such claim or any litigation resulting therefrom, shall be approved by Purchaser
(whose approval shall not  unreasonably be withheld),  and provided further that
the failure of  Purchaser  to give notice as provided  herein  shall not relieve
Seller of its obligations  under this Section 8.7, to the extent such failure is
not materially  prejudicial.  In the event the Seller  assumes the defense,  the
Seller shall have sole control over the management of the defense.  In the event
that Seller,  within 20 days after receipt of the aforesaid  notice of a Covered
Claim fails to assume the  defense of  Purchaser  against  such  Covered  Claim,
Purchaser  shall  have the  right  to  undertake  the  defense,  compromise,  or
settlement of such action on behalf of and for the account, expense, and risk of
Seller.  Seller,  in the  defense  of any such claim or  litigation,  shall not,
except with the written  consent of Purchaser,  consent to entry of any judgment
or enter into any  settlement  which does not include as an  unconditional  term
thereof the giving by the claimant or  plaintiff to such  Purchaser of a release
from all  liability  in  respect to such claim or  litigation.  Purchaser  shall
furnish such information regarding itself or the claim in question as Seller may
reasonably request in writing and as shall be reasonably  required in connection
with defense of such claim and litigation resulting  therefrom.  Notwithstanding
anything  in  this  Section  8.7 to  the  contrary,  if  there  is a  reasonable
probability  that a Covered Claim may  materially  adversely  affect  Purchaser,
Purchaser  shall have the right to participate in such defense,  compromise,  or
settlement.

                   Section 8.8 Limitation on Purchaser  Covenants.  In the event
of any Covered Claim, Purchaser agrees to use reasonable efforts,  provided such
efforts will not be materially burdensome or costly to Purchaser,  to modify any
product  that is the subject of a Covered  Claim so as to cause such  product to
not infringe the third party patent or other intellectual property rights giving
rise to such claim. Any intentional  failure by Purchaser to use such reasonable
efforts shall not provide an absolute limitation to Purchaser's  indemnification
rights hereunder,  but Purchaser's Damages shall be deemed reduced to the extent
that  Purchaser's  Damages  could have been  materially  reduced  had  Purchaser
exercised  such  reasonable  efforts as set forth  herein.  Purchaser and Seller
acknowledge  and agree  that  Sections  8.6 and 8.7 shall  provide  the sole and
exclusive  basis upon which Purchaser shall be entitled to assert Covered Claims
to the extent that any Covered Claim shall also constitute a breach by Seller of
its warranties and representations contained in Section 4.1(l) hereof.

                   Section 8.9 Accounts Receivable Collection.  Following the AR
Closing,  Purchaser agrees to: (i) use reasonable  commercial efforts to collect
the  Accounts  Receivable  (and such  efforts  shall be no less  diligent in all
material  respects  than  Purchaser  uses to  collect  its  accounts  receivable
generated in its own operations);  (ii) apply Seller's written standard accounts
receivable  collection  practices in the collection of the Accounts  Receivable;
(iii)  apply  proceeds  received  by Seller  from  debtors  under  the  Accounts
Receivable in order of maturity of the Accounts  Receivable  (and other existing
accounts   receivable  of  Purchaser  from  the  same  debtor);   and  (iv)  not
intentionally  compromise,  cancel, excuse or modify in any material respect any
Accounts Receivable without Seller's prior written consent,  which consent shall
not be  unreasonably  withheld.  Subject  to the  foregoing,  regardless  of any
disclosure  and to the extent that  Purchaser  is required to record a write-off
with respect to all or any portion of the Accounts Receivable in connection with
the preparation of its year

                                       36.

ended December 31, 1998 audited  financial  statements,  Seller hereby agrees to
fully  indemnify,  without  limitation  as set  forth in  Section  8.5,  and pay
Purchaser in cash within ten (10) days of notice from  Purchaser  fifty  percent
(50%) of the amount of Accounts Receivables to be written off. To the extent any
Accounts  Receivable  shall be written  off by  Purchaser  as  provided  in this
Section 8.8,  Purchaser  agrees,  on Seller's  request,  to assign such Accounts
Receivable to Seller, which, following such assignment, shall have the exclusive
right to collect such Account Receivable.  To the extent Purchaser shall collect
monies on such Accounts  Receivable,  Purchaser shall apply such monies first to
recover its out-of-pocket  costs for collection and then shall retain 50% of the
remaining  collected proceeds for its own account and promptly remit 50% of such
proceeds  to  Purchaser.  In the event that  Purchaser  writes off any  Accounts
Receivable in connection with this Section 8.9 or otherwise,  Purchaser shall be
entitled to retain the underlying product relating to such Accounts Receivable.

                                   TERMINATION

                   Section 9.1 Termination.  This Agreement may be terminated at
any time prior to the Time of Closing:

                         (a) by  Purchaser  or  Seller,  if the  Closing  is not
consummated within three (3) months of the date hereof;

                         (b) by mutual  agreement  of the Board of  Directors of
Purchaser and the Board of Directors of Seller;

                         (c) by Purchaser,  if there has been a breach by Seller
of any material  representation,  warranty,  covenant or agreement  set forth in
this  Agreement  which Seller fails to cure within  fifteen (15)  business  days
after notice thereof is given by Purchaser  (except that no cure period shall be
provided for a breach by Seller which by its nature cannot be cured);

                         (d) by Seller,  if there has been a breach by Purchaser
of any material  representation,  warranty,  covenant or agreement  set forth in
this Agreement,  which Purchaser fails to cure within fifteen (15) business days
after  notice  thereof is given by Seller  (except  that no cure period shall be
provided for a breach by Purchaser which by its nature cannot be cured);

                         (e) by Purchaser or Seller, if any permanent injunction
or other order of a court  preventing  the Closing  shall have become  final and
nonappealable  or shall render unlikely  within a reasonable  period of time the
consummation of the Closing on the terms contemplated hereby;

                         (f) by Purchaser or Seller, if any Governmental  Entity
shall have issued a  temporary  restraining  order,  preliminary  injunction  or
permanent injunction or other

                                       37.
                   
<PAGE>

order  preventing the  consummation  of the Closing or any  litigation  shall be
pending,  the ultimate  resolution of which is likely (i) in Purchaser's opinion
to result in the  issuance  of such an order or  injunction,  or the  imposition
against Purchaser of substantial damages if the Closing is consummated,  or (ii)
in  Purchaser's  or Seller's  opinion to render  Purchaser  or Seller  unable to
consummate the Closing; or

                         (g) by  Purchaser  or  Seller,  if the  inquiry  by the
Federal Trade Commission under HSR shall not have received early  termination or
any applicable HSR waiting period shall have expired by March 26, 1998.

                   Section 9.2 Authorization. Where action is taken to terminate
this Agreement pursuant to Section 9.1, it shall be sufficient authorization for
such action to be  authorized by the Board of Directors of the party taking such
action.

                   Section 9.3  Survival.  In the event of  termination  of this
Agreement  as  provided  in Section  9.1 or a failure to meet all of the closing
conditions,  this Agreement shall forthwith terminate without further obligation
of either  party to the other  party;  provided,  however,  that the  agreements
contained or referred to in Sections  5.1 and 10.4 shall  survive and be legally
enforceable,  and  provided,  further,  any  right  of a party  to any  legal or
equitable remedy,  including,  without  limitation,  the right to recover actual
damages  arising  as a result of any  breach  prior to such  termination  of any
warranty or covenant contained herein shall survive such termination.

bear its own costs and  expenses  in  connection  with  this  Agreement  and the
transactions  contemplated  hereby for its own account and Seller shall bear its

                   Section  10.5  Waiver;  Consent.  This  Agreement  may not be
changed, amended, terminated, augmented, rescinded, or discharged (other than by
performance),  in whole or in part,  except by a writing executed by the parties
hereto,  and no waiver of any of the  provisions or conditions of this Agreement
or any of the rights of a party hereto shall be effective or binding unless such
waiver  shall be in  writing  and  signed by the party  claimed to have given or
consented  thereto.  Except to the extent that a party hereto may have otherwise
agreed in writing, no waiver by that party of any condition of this Agreement or
breach by the other party of any of its obligations or representations hereunder
or  thereunder  shall  be  deemed  to be a  waiver  of any  other  condition  or
subsequent or prior breach of the same or any other obligation or representation
by the  other  party,  nor shall any  forbearance  by the first  party to seek a
remedy  for any  noncompliance  or breach  by the other  party be deemed to be a
waiver by the first  party of its  rights  and  remedies  with  respect  to such
noncompliance or breach.

                   Section 10.6 Third-Party  Beneficiaries.  Except as otherwise
expressly provided for in this Agreement,  nothing herein, expressed or implied,
is intended or shall be  construed  to confer upon or give to any person,  firm,
corporation,  or legal  entity,  other  than the  parties  hereto,  any  rights,
remedies, or other benefits under or by reason of this Agreement.

                   Section 10.7  Counterparts.  This  Agreement  may be executed
simultaneously  in  multiple  counterparts,  each of which  shall be  deemed  an
original,  but all of which taken  together  shall  constitute  one and the same
instrument.

                   Section 10.8 Severability.  If one or more provisions of this
Agreement are held to be  unenforceable  under  applicable  law, such  provision
shall be excluded from this Agreement and the balance of the Agreement  shall be
interpreted  as if such  provision  were so excluded and shall be enforceable in
accordance with its terms.

                   Section 10.9  Remedies of  Purchaser.  Seller agrees that the
Assets are unique and not otherwise readily available to Purchaser. Accordingly,
Seller  acknowledges  that, in addition to all other remedies to which Purchaser
is  entitled,  Purchaser  shall  have the  right to  enforce  the  terms of this
Agreement  by a decree of specific  performance,  provided  Purchaser  is not in
material default hereunder.

                   Section  10.10  Governing  Law. This  Agreement  shall in all
respects be construed in  accordance  with and governed by the laws of the State
of  California  without  regard to the  conflicts  or  choice of law  provisions
thereof.

                   Section 10.11  Arbitration; Attorneys' Fees.

                   (a) Any controversy  between the parties hereto involving the
construction  or  application  of any terms,  covenants  or  conditions  of this
Agreement  or any claims  arising out of or relating  to this  Agreement  or the
breach thereof will be settled by arbitration in Santa Clara County, California,
in accordance with the then current Commercial Arbitration Rules of the American
Arbitration Association (the "AAA"), and judgment upon the award rendered

                                       40.

by the arbitrators may be entered in any court having jurisdiction thereof. Such
arbitration  shall be  conducted  by three  (3)  arbitrators  chosen  by  mutual
agreement  of the parties  hereto,  or failing  such  agreement,  an  arbitrator
appointed by the AAA. There shall be limited  discovery prior to the arbitration
hearing as  follows:  (a)  exchange of witness  lists and copies of  documentary
evidence and documents related to or arising out of the issues to be arbitrated,
(b) depositions of all party witnesses, and (c) such other depositions as may be
allowed by the arbitrators  upon a showing of good cause.  Depositions  shall be
conducted  in  accordance  with  the  California  Code of Civil  Procedure,  the
arbitrator(s)  shall be  required to provide in writing to the parties the basis
for the award or order of such arbitrator(s),  and a court reporter shall record
all  hearings,  with such record  constituting  the official  transcript of such
proceedings.

                   (b) In the event of arbitration  filed or instituted  between
the  parties  with  respect  to this  Agreement,  the  prevailing  party will be
entitled  to receive  from the other  party all  costs,  damages  and  expenses,
including  reasonable  attorney's  fees,  incurred  by the  prevailing  party in
connection  with that action or  proceeding  whether or not the  controversy  is
reduced to judgment or award. The prevailing party will be that party who may be
fairly said by the arbitrator(s) to have prevailed on the major disputed issues.

                   Section 10.12 Cooperation and Records  Retention.  Seller and
Purchaser  shall  (i)  each  provide  the  other  with  such  assistance  as may
reasonably be requested by them in connection  with the  preparation  of any Tax
return,  statement,  report, form or other document (hereinafter  collectively a
"Tax  Return"),  or in  connection  with any audit or other  examination  by any
taxing  authority  or any  judicial or  administrative  proceedings  relating to
liability for Taxes, (ii) each retain and provide the other, with any records or
other  information  which  may be  relevant  to any  such Tax  Return,  audit or
examination,  proceeding or determination, and (iii) each provide the other with
any  final  determination  of any  such  audit  or  examination,  proceeding  or
determination  that affects any amount required to be shown on any Tax Return of
the other for any period.  Without  limiting the  generality  of the  foregoing,
Seller and Purchaser shall retain,  until the applicable  statute of limitations
(including any extensions) have expired,  copies of all Tax Returns,  supporting
work  schedules and other records or  information  which may be relevant to such
Tax Returns for all tax periods or portions  thereof  ending before or including
the Time of  Closing  and shall not  destroy  or  otherwise  dispose of any such
records without first providing the other party with a reasonable opportunity to
review and copy the same.  Seller shall keep the original copies of such records
relating to Seller,  as well as all books of accounts,  general  ledgers,  sales
invoices, accounts payable and payroll records, drawings, files, papers, and all
other records (the  "Records")  at its facility in  California  and, at Seller's
expense, shall promptly provide complete copies of the Records to Purchaser upon
Purchaser's  request and shall make all Records  available for inspection at any
time upon Purchaser's request.

         "Section 6.1 Time of Closing.  The  transactions  contemplated  by this
Agreement  shall be  completed  (the  "Closing")  on March 28, 1998 and shall be
legally effective as of 12:01 a.m.;  provided however,  that with respect to the
purchase and sale of the Accounts  Receivable,  the "AR Closing" and "AR Time of
Closing"  shall  refer to April 1,  1998.  The  Closing  shall take place at the
offices of Morrison & Foerster  LLP, 755 Page Mill Road,  Palo Alto,  California
94304.  The "Closing" shall mean the deliveries to be made by the parties hereto

         "; provided,  however, that notwithstanding  anything in Section 3.3(a)
or this Section 3.3(b) relating to the calculation of the Net Asset Amount,  for

allowance  for  doubtful  accounts)  plus  Related  Property  minus all  Assumed

determined by Price Waterhouse LLP, independent accountants,  in accordance with
GAAP  (provided  that no reduction in the value of the Related  Property for the

depreciation calculated in accordance with GAAP and past practice,  consistently
applied,  that would otherwise  accrue between December 31, 1997 and the Time of
Closing)."

         Except as set forth here, all other terms of the Asset  Agreement shall
remain in full force and effect.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
