                               PURCHASE AGREEMENT

         THIS AMENDED AND RESTATED  PURCHASE  AGREEMENT  (this  "Agreement")  is
dated as of August 18,  1999,  between  TRACOR,  INC.,  a  Delaware  corporation
("Buyer"), and WATKINS-JOHNSON COMPANY, a California corporation (the "Company;"
Buyer and the  Company  are  referred  to herein  individually  as a "Party" and
together as the  "Parties") and amends and restates in its entirety the Purchase
Agreement  dated  as of  the  same  date  between  the  Parties  (the  "Original
Agreement").


                                    RECITALS

         A. The Boards of Directors  of the Company and Buyer have  approved the
sale to Buyer,  on the terms and  subject  to the  conditions  set forth in this
Agreement,   of   substantially   all   of   the   assets   of   the   Company's
telecommunications equipment business, which designs,  manufactures and services
processes and related  equipment with  applications in government  intelligence,
signal surveillance and military communications (the "TG Business").

         B. The Board of Directors of the Company (the "Board") has  unanimously
determined  that this  Agreement is in the best  interests of the holders of the
Common Stock,  no par value,  of the Company  ("Company  Common  Stock") and the
Board has decided to recommend  the  approval and adoption of this  Agreement by
such holders.  The Board has made this decision  after having taken into account
(among other  factors) (i) the results of the  Company's  exploration,  with the
assistance  of its  investment  bankers  CIBC World  Markets  Corp.,  of various
alternatives for implementing the Board's strategy,  publicly announced on March
1,  1999,  to pursue  the sale of the  Company in its  entirety  or in  separate
transactions,  including the expressions of interest received by various parties
in addition to Buyer,  and (ii) the opinion of its  investment  bankers that the
estimated  consideration of $57,900,000 (subject to adjustment,  as specified in
this  Agreement)  to be received by the Company in respect of the sale of the TG
Business hereunder is fair to the Company from a financial point of view.

         C.  Buyer  and the  Company  desire  to make  certain  representations,
warranties and agreements,  and prescribe various conditions, in connection with
the foregoing.

         NOW, THEREFORE, the Parties hereby agree as follows:


                                    ARTICLE I

                              THE SALE TRANSACTION

         SECTION 1.1 Purchase  and Sale of the TG  Business.  Upon the terms and
subject  to

                                      -1-

<PAGE>


the  conditions  set forth in this  Agreement,  at the  Closing  (as  defined in
Section 2.1) the Company  shall sell,  assign,  transfer,  convey and deliver to
Buyer,  and Buyer shall purchase from the Company,  all of the Company's  right,
title and interest, as of the Closing, to and in the Included Assets (as defined
in Section 1.3).

         SECTION  1.2  Purchase  Price.  In  consideration  for the  sale of the
Included Assets pursuant to this Agreement,  Buyer shall (i) pay to the Company,
by  wire  transfer,   a  cash  payment  equal  to  $57,900,000  (the  "Estimated
Consideration"), and (ii) assume the Included Liabilities (as defined in Section
1.3).  The Estimated  Consideration  shall be subject to adjustment  pursuant to
Sections 1.4, 1.5 and 4.8(i) (as so adjusted, the "Adjusted Consideration").

         SECTION 1.3 Included and Excluded Assets and Liabilities. The "Included
Assets"  shall  consist of all the business,  properties,  assets,  goodwill and
rights of the Company of whatever kind and nature, real or personal, tangible or
intangible,  that are owned or leased by, or licensed  to, the Company as of the
Closing and used, held for use or intended to be used primarily in the operation
or conduct of the TG  Business,  including,  but not limited to, those assets of
the  Company  set forth on Schedule  1.3 as  Included  Assets,  other than those
assets  designated  in such Schedule as excluded (the  "Excluded  Assets").  The
"Included  Liabilities"  shall  consist only of those  liabilities  set forth on
Schedule 1.3 as Included  Liabilities  and shall exclude all of the  liabilities
designated  in such  Schedule  as excluded  (the  "Excluded  Liabilities)."  The
purchase  and  sale  of the  Included  Assets  between  the  Company  and  Buyer
hereunder,  and the assumption by Buyer of the Included  Liabilities  hereunder,
are together referred to as the "Sale Transaction."

         SECTION 1.4 Post Closing  Adjustment.  The Parties acknowledge that the
Estimated  Consideration was based upon the adjusted  unaudited balance sheet of
the TG  Business  at June 25,  1999 set  forth in  Schedule  1.4 (the  "Adjusted
Preliminary  Balance  Sheet  Value").  Within thirty (30) days after the Closing
Date  (as  defined  in  Section  2.1),  the  Company  shall  deliver  to Buyer a
certificate (the "Closing Certificate"). The Closing Certificate shall set forth
the  unaudited  balance  sheet of the TG Business  as of the  Closing  Date (the
"Adjusted Closing Date Balance Sheet"), which shall be (i) prepared on the basis
of generally  accepted  accounting  principles as in effect from time to time in
the United States  ("GAAP")  applied  consistently  with the manner in which the
Company  applied them  historically  (as reflected in the  financial  statements
specified in Section  3.1(h)(ii)) and (ii) adjusted in a manner  consistent with
the  adjustments  to the June 25, 1999  unaudited  balance  sheet  described  in
Schedule 1.4. The amount shown on the Adjusted Closing Date Balance Sheet as the
"Net Assets"  amount shall be shown on the Closing  Certificate as the "Adjusted
Closing Date Balance  Sheet Value." The Closing  Certificate  shall be signed by
the President or Executive Vice President of the Company. In addition,  in order
to verify the  Adjusted  Closing Date Balance  Sheet Value,  the

                                      -2-

<PAGE>


Company  shall,  immediately  prior  to the  Closing  or as soon as  practicable
thereafter,  with  the  reasonable  assistance  of  Buyer,  perform  a  physical
inspection  and count of the inventory  and  equipment  included in the Included
Assets to determine the value of those  Included  Assets as of the Closing Date.
Representatives  of the Buyer shall observe the physical  inventory,  inspection
and count.

         SECTION 1.5 Closing  Adjustment  Notice.  Buyer shall have  thirty-five
(35) days from the date of  receipt  of the  Closing  Certificate  to review the
Closing Certificate.  On or before the thirty-fifth (35th) day following receipt
of the Closing Certificate,  Buyer shall deliver to the Company a written notice
(the  "Closing  Adjustment  Notice")  either (i) stating  that Buyer  agrees and
accepts the  calculation  of the Adjusted  Closing Date Balance  Sheet Value set
forth in the Closing  Certificate or (ii) stating that Buyer does not agree with
such  calculation and setting forth Buyer's  calculation of the Adjusted Closing
Date Balance Sheet Value. The Parties shall in good faith attempt to resolve any
difference  between their  respective  calculations of the Adjusted Closing Date
Balance Sheet Value.  If the Parties do not resolve any such  difference  within
thirty-five (35) days after Buyer's delivery of the Closing  Adjustment  Notice,
they shall  engage the firm of  Deloitte & Touche LLP or, if such firm is unable
or  unwilling  to perform  such  services,  a mutually  agreed-upon  independent
accounting firm of national standing and reputation (the "Accounting  Firm"), to
determine the Adjusted Closing Date Balance Sheet Value.  Such  determination by
the Accounting  Firm shall be final and binding on the Parties.  The cost of the
services of the Accounting Firm shall be borne by the Party whose  determination
of  the  Adjusted   Closing  Date  Balance  Sheet  Value  is  further  from  the
determination of the Accounting Firm or, if the  determination by the Accounting
Firm is equally distant from the Parties' respective valuations, the costs shall
be split equally between the Parties.  The Accounting Firm shall  determine,  in
accordance with the principles set forth in the foregoing sentence,  which Party
shall bear the costs of the Accounting  Firm's  services.  Each Party shall, and
shall use reasonable efforts to cause its officers,  directors and employees to,
cooperate,  with the  other  Party  and the  Accounting  Firm to  determine  the
Adjusted Closing Date Balance Sheet Value by furnishing information,  documents,
evidence  and other  assistance  to the other Party and the  Accounting  Firm to
facilitate  the  completion  of the review  and  determination  of the  Adjusted
Closing Date Balance  Sheet Value.  If the Adjusted  Closing Date Balance  Sheet
Value is less than the Adjusted  Preliminary  Balance  Sheet Value,  the Company
shall pay Buyer the difference in cash within ten (10) business days after final
determination  of the  Adjusted  Closing Date  Balance  Sheet Value  (whether by
mutual agreement between the Parties or by the Accounting Firm). If the Adjusted
Closing  Date  Balance  Sheet  Value is greater  than the  Adjusted  Preliminary
Balance Sheet Value,  Buyer shall pay the Company the  difference in cash within
ten (10) business days after final  determination  of the Adjusted  Closing Date
Balance Sheet Value (whether by mutual  agreement  between the Parties or by the
Accounting Firm).

         SECTION 1.6 Title Insurance and Survey.

                           (i) Prior to the  Closing,  the  Company  shall  have
obtained  for the  benefit of Buyer,  in  connection  with the  transfer  of the
property in Gaithersburg, Maryland listed on Schedule 1.6(i) (the "Property") at
the Closing, a signed commitment for the issuance of a 1970 ALTA title insurance
policy with respect to the Property (the "Title  Policy") and an insured closing
letter to be issued to Buyer at the Closing,  issued by Lawyers Title  Insurance
Company  or such  other  reputable  title  insurance  company  as is  reasonably
acceptable to Buyer (the "Title  Company")  with a CLTA Form 100,  Comprehensive
Endorsement,  or local  equivalent,  and (subject to Section 1.6(ii)) such other
endorsements as may be available in Maryland and requested by Buyer prior to the
Closing,  which Title Policy shall (1) omit (or modify, so as to comply with the
Company's  representations  in Section  3.1(q)(ii) that the Property is free and
clear of all  liens and  encumbrances  except  for  Permitted  Encumbrances  (as
defined in clause (iii) below)),  the so-called 'printed  exceptions'  (included
among  which,  among  others,  are a  survey  exception  and  an  exception  for
unrecorded leases, options, easements and other restrictions not of record), and
(2) insure Buyer's  acquisition of good and marketable fee title to the Property
from the  Company,  free and  clear of all  liens and  encumbrances  other  than
Permitted  Encumbrances,  the amount of the Title  Policy to be in the amount of
$10  million.  In order to obtain such  deletion (or such  modification)  of the
'printed  exceptions'  from the Title Policy by the Title  Company,  the Company
shall  execute  and  deliver  to the Title  Company  prior to the  Closing  such
customary  Owners' Title Affidavit as the Title Company may require to enable it
to so delete (or so modify) the 'printed  exceptions'  (the "Title  Affidavit").
The Title  Policy  shall be in full  force and  effect  at the  Closing  for the
benefit of Buyer.  The  Company  has  delivered  to Buyer an ALTA  Survey on the
Property  (the  "Survey")  and shall,  as promptly  and  reasonably  practicable
following  the date of this  Agreement,  and in any event no later than ten (10)
days prior to the Closing Date,  cause the Survey to be redated and certified to
Buyer and deliver the same to Buyer. The cost of the Title Policy and the Survey
shall be shared equally by Buyer and the Company.  Except as otherwise  provided
in  Section  4.8(i),  all  other  costs  associated  with  the  transfer  of the
Properties (including all Closing costs) shall be borne by the Company.

                           (ii) Buyer  acknowledges  that the  Company  has made
available to Buyer a preliminary title report (the "Title Report")  delivered by
the Title  Company with respect to the Property and  documents  and  information
pertaining  to the  exceptions  to title listed in the Title  Report.  Buyer may
secure at its sole cost any additional title report or survey updates desired by
Buyer. Any title exceptions or issues disclosed by the Title Report, the Survey,
any preliminary  title report or survey updates  obtained by Buyer, or otherwise
affecting  the Property  shall be referred to as the "Title  Exceptions."  Buyer
shall have the right to request that the Title  Company  provide at Buyer's sole
cost and  expense  any  endorsements  Buyer  shall  request,  provided  that the
issuance of such endorsements shall not be a condition to or delay the Closing.

zoning ordinances and regulations and other laws or regulations governing use or
enjoyment of the Property; (3) liens to secure taxes and assessments not yet due
and  payable;  and (4) Title  Exceptions  caused by or created  with the written
consent of Buyer.  Notwithstanding  the  foregoing,  Seller  shall remove at the
Company's  sole cost and  expense,  on or prior to the Closing Date any monetary
liens or any mortgages or deeds of trust securing  indebtedness  of the Company,
which shall not be treated as Permitted Encumbrances.

                           (iv) The Company  shall have no obligation to execute
any affidavits or  indemnifications in connection with the issuance of the Title
Policy  excepting  only (1) the Owners' Title  Affidavit  referred to in Section
1.6(i) and (2) customary  affidavits  as to authority,  the rights of tenants in
occupancy and the status of mechanics' liens.

         SECTION 1.7 Escrow Fund. At the Closing,  Buyer shall deliver, or cause
to be delivered, to an escrow agent to be selected prior to Closing (the "Escrow
Agent") an amount in cash  equal to  $1,000,000  (the  "Escrow  Amount"),  to be
deducted  from  the  Estimated  Consideration  and held in the  Escrow  Fund (as
defined  in Section  4.7(e))  pursuant  to the terms set forth  herein and in an
escrow  agreement  to be entered  into by and among  Buyer,  the Company and the

                         REPRESENTATIONS AND WARRANTIES

         SECTION 3.1  Representations  and Warranties of the Company.  Except to
the extent that any of the following representations and warranties is qualified
by a  Schedule  that  (i) is  included  in the  Company's  Disclosure  Schedules
delivered  to Buyer at the same  time as the  execution  of this  Agreement  and
accepted by Buyer under this Agreement (the "Company Disclosure  Schedules") and
(ii) specifically  identifies the  representation and warranty qualified by such
Schedule (in which case,  the  specified  representation  and warranty  shall be
deemed made with such qualification), the Company hereby represents and warrants
to Buyer as follows:

                  (a) Organization of the Company.  The Company is a corporation
duly  organized,  validly  existing and in good  standing  under the laws of the
State of California and has the requisite  corporate power and authority and any
necessary governmental approvals to own, lease and operate its properties and to
carry on its business as it is now being conducted,  except where the failure to
be so organized,  existing and in good standing or to have such power, authority
and  governmental  approvals  could  not,  individually  or  in  the  aggregate,
reasonably be expected to have a TG Business Material Adverse Effect (as defined
below in this Section  3.1(a)).  The term "TG Business  Material Adverse Effect"
means (to the  exclusion  of any other  meaning) any of the  following:  (i) any
adverse change in or effect on the business,  results of operations or condition
(financial  or other)  of the TG  Business  with a  reasonably  estimable  value
(measured, as of the date of determination, by reference to operating profit, as
determined in accordance with GAAP applied consistently with the manner in which
the  Company  prepared  the TG  Financial  Statements  (as  defined  in  Section
3.1(h)(ii)),  of at least  $1,279,000 (it being agreed that, for all purposes of
this  Agreement,  there shall be only a single test of $1,279,000  applicable to
determine the  existence of a TG Business  Material  Adverse  Effect not only in
connection with any individual  provision of this Agreement which refers to a TG
Business Material Adverse Effect but also in connection with all such provisions
taken collectively and such test shall be applied to each such provision and all
such provisions taken collectively (including all the provisions of this Section
3.1) on the basis of the  cumulative  effect on operating  profit of all of such
material  adverse changes and effects);  (ii) any material  adverse change in or
effect on the ability of the Company to consummate the Sale  Transaction  before
the Terminal Date (as defined in Section  6.1(e));  or (iii) any debarment order
issued by the U.S. Government (as defined in Section 3.1(s)(vii)) precluding the
Company from bidding on or performing any present or future Government  Contract
(as defined in Section 3.1(s)) and any written  allegation that could, as of the
determination date (in light of all relevant facts and circumstances,  including
the Company's position with respect to such allegation), be reasonably viewed as
likely to result in any such debarment order.

                                      -8-

<PAGE>


                  (b)  Qualification  of  the  Company.   The  Company  is  duly
qualified or licensed as a foreign  corporation  to do business,  and is in good
standing,  in each  jurisdiction  where the character of the  properties  owned,
leased  or  operated  by  it  or  the  nature  of  its  activities   makes  such
qualification  or licensing  necessary,  except for such  failures to be so duly
qualified or licensed and in good standing which could not,  individually  or in
the  aggregate,  reasonably be expected to have a TG Business  Material  Adverse
Effect.

                  (c) Articles of  Incorporation  and  By-Laws.  The Company has
furnished to Buyer a complete and correct copy of the Articles of  Incorporation
and the By-Laws of the  Company as  currently  in effect.  The Company is not in
violation of any of the provisions of such Articles of Incorporation or By-Laws.

                  (d)  Capitalization.  The  authorized  capital  stock  of  the
Company consists of 45,000,000 shares of Company Common Stock and 500,000 shares
of preferred stock, $1.00 par value ("Company  Preferred Stock"). As of June 25,
1999: (i) 6,569,021  shares of Company Common Stock were issued and outstanding,
all of which are validly issued, fully paid and nonassessable and not subject to
preemptive  rights;  and (ii)  1,546,979  shares of  Company  Common  Stock were
issuable pursuant to outstanding  options previously  granted to employees,  non
employee  directors and consultants to purchase Company Common Stock pursuant to
the  Company's  stock  option  plans (the "Stock  Option  Plans").  No shares of
Company Preferred Stock are outstanding.

                  (e)  Authority  Relative  to  Agreement.  The  Company has all
necessary  corporate  power and authority to execute and deliver this Agreement,
to perform its  obligations  under this  Agreement  and to  consummate  the Sale
Transaction.  The execution,  delivery and  performance of this Agreement by the
Company have been duly and validly authorized by all necessary  corporate action
and no other  corporate  proceedings on the part of the Company are necessary to
authorize this Agreement or to consummate the Sale  Transaction,  other than the
approval of this Agreement and the Sale  Transaction by the  shareholders of the
Company. This Agreement has been duly executed and delivered by the Company and,
assuming the due authorization, execution and delivery by the Buyer, constitutes
a legal,  valid and binding  obligation of the Company  enforceable  against the
Company in accordance with its terms.  The only vote of the holders of any class
or series of outstanding securities of the Company required for approval of this
Agreement  is  the  affirmative  vote  of  the  holders  of a  majority  of  the
outstanding shares of Company Common Stock.

connection  with  or in  compliance  with  the  specific  provisions  of (i) the

with the SEC relating to this Agreement or any of the transactions  contemplated
hereby,   (iii)  the  "blue  sky"  laws  of  the   various   states,   (iv)  the

"Governmental Entity"),  applicable to the Company or by which any of properties
or assets of the TG  Business  may be bound;  (3) require  any filing  with,  or
permit, consent or approval of, or the giving of any notice to, any Governmental

failure to obtain or make any such filing,  permit,  consent, or approval or the
failure to give such notice or (B) in the case of  sub-clause  (4) above,  where
such  violation,  could not,  individually  or in the  aggregate,  reasonably be
expected to have a TG Business Material Adverse Effect.

                  (g) Compliance  with Laws.  The Company is in compliance  with
all applicable laws, regulations, orders, judgments and decrees except where the
failure to so comply could not, individually or in the aggregate,  reasonably be

action, proceeding or investigation pending or, to the knowledge of the Company,
overtly  threatened  against  the  Company by, on behalf of or before any court,
arbitrator or Governmental Entity which, individually or in the aggregate, could
reasonably  be  expected  to have a TG  Business  Material  Adverse  Effect.  No
investigation by any Governmental  Entity with respect to Company is pending or,
to the knowledge of the Company,  overtly threatened,  other than, in each case,
those  the  outcome  of  which,  individually  or in the  aggregate,  could  not
reasonably be expected to have a TG Business Material Adverse Effect.

                           (i) Since  December 31,  1995,  the Company has filed
all  forms,  reports  and  documents  with  the SEC  required  to be filed by it
pursuant  to the  Federal  securities  laws and the SEC  rules  and  regulations

Company  during such period (the  "Company SEC  Filings")  have  complied in all
material  respects with all applicable  requirements  of the Federal  securities
laws and the SEC rules and  regulations  adopted  under those laws.  As of their
respective  dates,  the Company SEC Filings did not contain any untrue statement
of a  material  fact or omit to state a  material  fact  required  to be  stated
therein  or  necessary  to  make  the  statements   therein,  in  light  of  the
circumstances  under  which  they  were  made,  not  misleading.   Each  of  the
consolidated  financial  statements  included  in the  Company  SEC  Filings was
prepared in accordance with GAAP applied on a consistent basis (except as may be
indicated therein or in the notes or schedules thereto), and fairly presented in
all material respects the consolidated financial position of the Company and its

Schedules  sets  forth the  unaudited  balance  sheet of the TG  Business  as of
December  31, 1998 and the related  unaudited  statements  of earnings  and cash

sheet  of the TG  Business  as of  June  25,  1999  and  the  related  unaudited
statements  of earnings and cash flows for the six  (6)-month  period then ended
(collectively,  the "TG Interim  Financials" and,  together with the TG Year-End
Financials, the "TG Financial Statements").  Each of the TG Financial Statements
was prepared in  accordance  with GAAP applied on a consistent  basis (except as
may be  indicated  therein  or in the notes or  schedules  thereto),  and fairly
presented in all material respects the financial  position of the TG Business as
of the date of such TG Financial  Statement and the results of operations of the
TG Business and its cash flows for the period then ended  (subject,  in the case
of the TG Interim Financials, to normal year-end adjustments).

                           (iii) The Company will  deliver to Buyer,  as soon as
they  become  available,  true and  complete  copies of any report or  statement
mailed by the Company to its shareholders generally or filed by the Company with
the SEC subsequent to the date of this Agreement and prior to the Closing. As of
their  respective  dates,  such reports and  statements  (excluding  any written
information provided for inclusion therein by or on behalf of Buyer, as to which
the Company makes no representation)  will not contain any untrue statement of a
material fact or omit to state a material fact required to be stated  therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they are made,  not  misleading  and will comply in all material  respects
with all

                                      -11-

<PAGE>


applicable  requirements  of the Federal  securities  laws and the SEC rules and
regulations thereunder.  The consolidated financial statements of the Company to
be included in such reports and statements  (excluding any  information  therein
provided by Buyer,  as to which the  Company  makes no  representation)  will be
prepared in accordance with GAAP applied on a consistent basis (except as may be
indicated therein or in the notes or schedules thereto), and will fairly present
in all material respects the consolidated  financial position of the Company and
its consolidated  subsidiaries as of the respective  dates of such  consolidated
financial  statements  and the results of their  operations and their cash flows
for the  respective  periods then ended  (subject,  in the case of any unaudited
financial statements, to normal year-end audit adjustments).

                  (i) Information Supplied.

                           (i) None of the  information  included  in the  Proxy
Statement  (other  than  information  supplied  by or on  behalf  of  Buyer  for
inclusion in the Proxy  Statement) will contain,  at the date it is first mailed
to the Company's  shareholders  or at the time of the  Shareholders  Meeting (as
defined in Section 4.2), any statement which, in the light of the  circumstances
under which such  statement is made, is false or misleading  with respect to any
material fact, or omit to state any material fact necessary in order to make the
statements therein not false or misleading or necessary to correct any statement
in any earlier  communication  with respect to the solicitation of any proxy for
the Shareholders Meeting or any amendment or supplement thereto.

                           (ii) The Proxy  Statement  will  comply as to form in
all material  respects with the requirements of the Exchange Act except that the
Company makes no  representation  with respect to any  statements  made based on
information  supplied  by or on  behalf  of Buyer  for  inclusion  in the  Proxy
Statement.

                  (j) Absence of Certain Changes or Events.  Except as disclosed
in any Company SEC Filing made on or before July 30,  1999,  since June 25, 1999
there has not been (i) any change,  event or  development in or affecting the TG
Business that, individually or in the aggregate, constituted or could reasonably
be expected to have a TG Business  Material  Adverse Effect,  (ii) any change by
the Company in its accounting  methods,  principles or practices relating to the
TG  Business,  except as  required by changes in GAAP or as  recommended  by the
Company's  independent  accountants,  or (iii)  with  respect  to any  employees
directly involved (solely or primarily) in the TG Business (the "TG Employees"),
any increase in or establishment of any bonus,  insurance,  severance,  deferred
compensation,  pension,  retirement,  profit sharing,  stock option  (including,
without limitation,  the granting of stock options,  stock appreciation  rights,
performance  awards,  or  restricted  stock  awards),  stock  purchase  or other
employee benefit plan or agreement or arrangement,  or any other increase in the
compensation  payable or to become  payable to any present or former TG Employee
at or above the rank

                                      -12-

<PAGE>


of Vice President for the TG Business, except for increases in base compensation
and annual cash  bonuses,  in each case in the  ordinary  course of business and
consistent with past practice.

                  (k)  Absence  of  Litigation.  There  are  no  suits,  claims,
actions, proceedings or investigations pending or overtly threatened against the
TG Business or any properties of the Company  relating to the TG Business before
any court,  arbitrator or other Governmental Entity. Neither the Company nor any
of its respective properties or assets used in the TG Business is subject to any
order, writ, judgment,  injunction,  decree,  determination or award relating to
the TG  Business.  The  updated  Schedule  3.1(k) to be provided to Buyer at the
Closing in  accordance  with  Section  5.2(a)  shall be true and  correct in all
respects as of the Closing.

                  (l) Liabilities.  Other than regular  quarterly cash dividends
on Company  Common  Stock,  since June 25,  1999  neither the Company nor the TG
Business  has  incurred  any  material   outstanding   claims,   liabilities  or
indebtedness, contingent or otherwise, that would be required to be disclosed in
the Company's consolidated financial statements (or the notes thereto) or the TG
Financial Statements (or the notes thereto), in each case prepared in accordance
with GAAP, applied on a consistent basis, other than liabilities incurred in the
ordinary course of business not involving borrowings by the Company.

                  (m) Labor  Matters.  The Company has  complied in all respects
with all laws,  rules and  regulations  pertaining to employment  practices with
respect  to  the  TG  Employees,   including,  without  limitation,  the  Worker
Adjustment  Retraining  Notification Act, the wage hour laws, the Americans with
Disabilities Act, and the discrimination  laws, and no fact or event exists with
respect to the TG Employees  that could give rise to liability  under such acts,
laws,  rules or regulations,  except for such  occurrences,  noncompliances  and
liabilities  as could  not,  individually  or in the  aggregate,  reasonably  be
expected to have a TG Business  Material  Adverse  Effect.  The Company is not a
party to any collective  bargaining  agreement with respect to the TG Employees.
Since December 31, 1995, the Company has not (i) had any employees strikes, work
stoppages, slowdowns or lockouts with respect to the TG Employees, (ii) received
any requests for  certifications  of bargaining  units or any other requests for
collective bargaining with respect to the TG Employees, or (iii) become aware of
any efforts to organize the TG Employees into a collective bargaining unit.

                  (n) Environmental Matters.

                           (ii)  Except as could  not  reasonably  be  expected,
individually or in the aggregate,  to result in a TG Business  Material  Adverse
Effect:  (1) the  Company  is and has been in  compliance  with  all  applicable
Environmental  Laws in  connection  with the TG  Business;  (2) the  Company has

material  is in  violation  of any  applicable  Environmental  Laws and,  to the

and used in connection with the TG Business; (5) the Company has not, and to the
Company's  knowledge no other person has,  released,  discharged  or disposed of
Hazardous Substances on any real property presently owned, leased or operated by

property  contains any  Hazardous  Substances at a  concentration  level or in a
quantity that is reportable under any  Environmental  Laws and, to the Company's

any real property formerly owned,  leased or operated by the Company and used in
connection with the TG Business; (6) the Company is not undertaking, and has not
completed,  any  investigation  or  assessment  or remedial  or response  action
relating to any such prior  release,  discharge or disposal of or  contamination

are no (A) pending, past or overtly threatened actions,  suits, demands,  demand
letters,  claims,  liens,  notices of  non-compliance  or violation,  notices of
liability or potential liability, investigations, proceedings, consent orders or
consent agreements relating to any Environmental Laws, any Environmental Permits
or any  Hazardous  Substances  ("Environmental  Claims")  against the Company in
connection  with the TG  Business or  relating  to any real  property  presently
owned,  leased or operated by the  Company  and used in  connection  with the TG
Business,  or (B)  circumstances  that could  reasonably be expected to form the
basis of any Environmental  Claim,  including without limitation with respect to
any off-site disposal location  presently used by the Company in connection with
the TG Business and, to the  Company's  knowledge,  the foregoing  statements in

                  (o)  Employee   Benefits.   Schedule  3.1(o)  of  the  Company
Disclosure  Schedules  lists  (i)  all  employee  benefit  plans,  programs  and
arrangements  maintained  for the benefit of any current or former TG  Employee,
other  than the  Stock  Option  Plans  (the  "TG  Plans")  and (ii) all  written
agreements  relating to  employment  or  severance  with any of the TG Employees
other than, in each case,  any such  agreement that is terminable by the Company
at will without penalty or other consequence (the "TG Employment

                                      -15-

<PAGE>


Contracts").  Schedule 3.1(o) of the Company Disclosure  Schedule sets forth the
name of each  current  TG  Employee  with an annual  base  salary  greater  than
$150,000 and the annual base  compensation  applicable to each such TG Employee.
The Company has made  available to Buyer a copy of each TG Plan,  each  material
document  prepared  in  connection  with  each TG Plan  and  each TG  Employment
Contract.  None of the TG Plans is a "multi employer plan" within the meaning of
Sections 3(34) and 4007(a)(3) of the Employee  Retirement Income Security Act of
1974, as amended ("ERISA").  None of the TG Plans or the TG Employment Contracts
promises or provides  retiree medical or retiree life insurance  benefits to any
person.  Each TG Plan  intended  to be  qualified  under  Section  401(a) of the
Internal  Revenue  Code, as amended (the "Tax Code"),  is so qualified.  Each TG
Plan has been operated in all material respects in accordance with its terms and
the  requirements  of  applicable  law.  Neither  the  Company  nor  any  of its
affiliates has incurred any direct or indirect material liability under, arising
out of or by operation of Title IV of ERISA in connection  with the  termination
of, or  withdrawal  from,  any TG Plan or any other plan  subject to Title IV of
ERISA and no fact exists or event has occurred that could reasonably be expected
to give  rise to any  such  liability.  No TG Plan is  subject  to,  or has been
covered by, Title IV of ERISA or Section 412 of the Tax Code. All  contributions
required  to have been made to the TG Plans  have been  timely  made.  Except as
provided  in the TG Plans and the TG  Employment  Contracts  listed on  Schedule
3.1(o),  no TG  Employee  will be  entitled  to any  additional  benefits or any
acceleration  of the time of payment or vesting of any  benefits  as a result of
the Sale Transaction.

                  (p) Tax Matters.

                           (i) For the purposes of this Agreement: (1) "Tax" or,
collectively,  "Taxes," means: (A) any and all Federal, state, local and foreign
taxes,  assessments  and other  governmental  charges,  duties,  impositions and
liabilities,  including taxes based upon or measured by gross receipts,  income,
profits,  sales,  use and  occupation,  and value added,  ad valorem,  transfer,
franchise,  withholding,  payroll,  recapture,  employment,  excise and property
taxes, together with all interest,  penalties and additions imposed with respect
to such  amounts;  (B) any  liability for the payment of any amounts of the type
described  in  clause  (A) as a  result  of  being a  member  of an  affiliated,
consolidated,  combined or unitary  group for any period;  and (C) any liability
for the payment of any amounts of the type  described  in clause (A) or (B) as a
result of any express or implied  obligation to indemnify any other person or as
a result of any obligations  under any agreements or arrangements with any other
person with respect to such amounts and  including  any liability for Taxes of a
predecessor  entity;  and (2) "Return" means Federal,  state,  local and foreign
returns, estimates, information,  statements and reports relating to any and all
Taxes concerning or attributable to the Included Assets or the TG Business.

                                      -16-

<PAGE>


                           (ii) The Company,  and any affiliated  group,  within
the meaning of Section 1504 of the Tax Code, of which the Company is or has been
a member,  has:  (1) filed all  Returns  required to be filed by it prior to the
date of this  Agreement  (taking  into account  extensions);  (2) paid all Taxes
shown as due on such Returns and paid all  applicable ad valorem and value added
Taxes as are due;  and (3) paid all Taxes with  respect to the TG  Business  for
which a notice of assessment or collection has been received (other than amounts
being contested in good faith by appropriate  proceedings),  except, in the case
of clauses (1), (2) and (3), for any such filings and payments  which could not,
individually  or in the aggregate,  reasonably be expected to have a TG Business
Material  Adverse  Effect.  Neither the Internal  Revenue  Service nor any other
Federal,  state, local or foreign taxing authority (a "Tax Agency") has asserted
in writing any claims for Taxes with respect to the TG Business,  which  claims,
individually  or in the  aggregate,  could  reasonably  be expected to have a TG
Business Material Adverse Effect. The Company has withheld or collected and paid
over to the appropriate Tax Agency (or is properly holding for such payment) all
Taxes  required  by law to be  withheld  or  collected  with  respect  to the TG
Business,  except for amounts which could not, individually or in the aggregate,
reasonably be expected to have a TG Business Material Adverse Effect.  There are
no liens for Taxes upon the Included Assets (other than liens for Taxes that are
not  yet  due  or  that  are  being  contested  in  good  faith  by  appropriate
proceedings),  except  for  liens  which  could  not,  individually  or  in  the
aggregate, reasonably be expected to have a TG Business Material Adverse Effect.

                           (iii) None of the Included  Assets is treated as "tax
exempt use property," within the meaning of Section 168(h) of the Tax Code.

                           (iv) Neither the Company nor any of its  subsidiaries
has given,  with  respect to the Company or any assets of the TG  Business,  any
consent under Section 341 of the Tax Code.

                           (v)  None of the  Included  Assets  is a  lease  made
pursuant to Section 168(f)(8) of the Tax Code.

                           (vi) The Company is not a "foreign person" within the
meaning of Section 1445 of the Tax Code.

                  (q) Tangible Property.

                           (i) As of the Closing, the Company will have good and
marketable title to all tangible  properties and assets included in the Included
Assets,  with only such exceptions as,  individually or in the aggregate,  could
not  reasonably  be  expected  to have a TG Business  Material  Adverse  Effect;
provided, however, that the foregoing representation is not made with respect to
the Property,  the TG Leases (as defined in Section  3.1(q)(iii))  and any other
interests in real property included in the Included

                                      -17-

<PAGE>


Assets,  as to all of which the  representations  contained in the next sentence
and in sections 3.1(q) (ii) and (iii) below, as applicable,  shall apply. All of
the tangible  properties  and assets  included in the Included  Assets have been
maintained and repaired for their continued  operation and are in good operating
condition,  reasonable wear and tear excepted, and usable in the ordinary course
of business.

                           (ii) All of the Included Assets are free and clear of
all liens and encumbrances,  except (1) liens for taxes not yet due and payable,
(2) liens of landlords,  vendors,  warehousemen and mechanics, and (3) Permitted
Encumbrances.  To the knowledge of the Company,  all real estate properties that
are  Included  Assets  (whether  owned or  leased)  are in  compliance  with all
applicable laws, statutes, rules and regulations (including, without limitation,
building  and  zoning  laws)  and all  covenants,  conditions,  restrictions  or
easements affecting the property or its use or occupancy,  the failure to comply
with which could,  individually  or in the aggregate,  reasonably be expected to
have a TG Business Material Adverse Effect,  and no notices of any such failures
to  comply  have been  received  by the  Company;  provided,  however,  that the
foregoing  representation is not made with respect to Environmental  Laws, as to
which the representations contained in Section 3.1(n) shall apply.

                           (iii) Each of the leases (the "TG Leases")  listed as
an  Included  Asset is  unmodified  and in full force and  effect  (and true and
complete copies thereof, together with any additional amendments and supplements
thereto,  have been delivered to Buyer and are included in Section 3.1(q) of the
Company Disclosure Schedule,  and, to the knowledge of the Company, there are no
other  agreements,  written or oral,  between the Company and any third  parties
claiming an interest in the interest of the Company in, or  otherwise  affecting
the use and occupancy of, the property  leased under each TG Lease.  The Company
is not in material default under the TG Leases, no material defaults (whether or
not subsequently cured) by the Company have been alleged thereunder and no event
has  occurred  that,  with the giving of notice or the  passage  of time,  would
constitute a material default  thereunder.  To the knowledge of the Company,  no
lessor named in any of the TG Leases is in default  thereunder,  and no defaults
(whether or not subsequently cured) by such lessor have been alleged thereunder.

                  (r) Certain Contracts and Agreements.

                           (i)  Schedule  3.1(r)(i)  of the  Company  Disclosure
Schedules lists each contract (other than a Government  Contract,  as defined in
Section  3.1(s),  and any  contract  listed in  Section  3.1(v)  of the  Company
Disclosure  Schedule)  in  effect  as of June 25,  1999 and  relating  to the TG
Business  which is required by its terms or is  currently  expected to result in
the  payment or receipt by the  Company of more than  $200,000  and which is not
terminable by the Company without the payment of any penalty or fine on not more
than three months' notice, other than the TG Plans (a "TG Material Contract").

                                      -18-

<PAGE>


Each TG Material Contract is, to the knowledge of the Company, in full force and
effect and is enforceable  against the parties  thereto (other than the Company)
in  accordance  with its terms and no  condition  or state of facts exists that,
with notice or the passage of time, or both, would constitute a material default
by the Company or, to the knowledge of the Company, any third party under any TG
Material  Contract.  The Company has duly complied in all material respects with
the provisions of each TG Material Contract to which it is a party.

                           (ii) Schedule  3.1(r)(ii)  of the Company  Disclosure
Schedules lists: (1) all agreements relating to joint ventures, partnerships and
equity  or debt  investments  involving  the TG  Business;  (2) all  non-compete
agreements with the Company relating to the TG Business  (whether as beneficiary
or obligor); (3) all agreements,  notes, bonds,  indentures or other instruments
governing  indebtedness  for  borrowed  money of the Company  relating to the TG
Business,  and any  guarantee  thereof  or the  pledge  of any  assets  or other

party, which are not cancelable without penalty or further payment upon 30 days'
or less notice;  and (7) each other agreement of the Company  relating to the TG
Business not made in the ordinary  course of business that is to be performed on
or after  the date of this  Agreement,  except  for any  agreement  (A) which is
required by any other  provision of this Section 3.1 to be included on a Company
Disclosure Schedule delivered under that provision,  or (B) the termination,  or
breach of any provision,  of which agreement could not reasonably be expected to
have a TG Business Material Adverse Effect.

                  (s) Government Contracts.

                           (i)  Schedule   3.1(s)  of  the  Company   Disclosure

                           (ii) Except for such matters as could not  reasonably
be  expected,  individually  or in the  aggregate,  to result  in a TG  Business
Material Adverse Effect, the Company has, since December 31, 1986, complied with
all applicable  requirements of the U.S.  Government Cost Accounting  Standards,
the Federal Truth in Negotiations Act and other U.S. laws, rules, regulations or
orders applicable to Government Contracts or Bids.

                           (iii) Except for such matters as could not reasonably
be expected,  individually or in the aggregate, to result in a loss (a "Relevant
Loss") of at least $250,000  individually  or $500,000 when  aggregated with all
other  such  losses,   Schedule  3.1(s)  of  the  Company  Disclosure  Schedules

costs  (direct and  indirect)  incurred or currently  expected to be incurred in
connection   with  any   fully-funded   Government   Contract  will  exceed  any

recognize a loss at the gross profit level  (determined in accordance  with GAAP
applied on a basis  consistent with the preparation of the financial  statements
referred to in Schedule  3.1(h)(ii)  of the Company  Disclosure  Schedules))  in
connection  with  such  Government  Contract;  (4) in the  case of a  multi-year

March 31, 1999.

                           (iv) Except for such matters as could not  reasonably
be expected, individually or in the aggregate, to result in a Relevant Loss: (1)
to the Company's  knowledge,  there are no audits (other than those conducted in
the ordinary course of business) of any Government  Contracts being conducted by
the U.S.  Government,  a prime  contractor  of the U.S.  Government or any other
party to any  Government  Contract;  (2) except to the extent  that the same has
been  finally  resolved  (and any  liability  relating  thereto has been paid or
reflected in the balance sheet referred to in Section  3.1(h)(ii)),  the Company
has not,  with respect to any current  Government  Contract,  received:  (A) any
written cure notice or show cause notice (as defined in the Federal  Acquisition
Regulation Part 49, P. 49.607(a) and (b),  respectively)  pursuant to applicable
contract default  provisions or  notice-of-default  provisions;  (B) any written
contract termination, whether for default, convenience,  cancellation or lack of
funding or other  reasons;  (C) any  written  final  decision  assessing a price

(as  defined  in the  Federal  Acquisition  Regulation  at P.  33,201)  based on
assertions of defective  pricing or violations  of  government  cost  accounting
standards  or  cost  principles;  (E)  any  written  request  for  an  equitable
adjustment of, or claim (as defined in the Federal  Acquisitions  Regulations at
P.  33,201)  concerning,  such  Government  Contract  by any  of  the  Company's
customers,  subcontractors or suppliers;  (F) any written disallowance,  written
questioning or other written challenging of material costs (direct or indirect);
or (G) any written notice of any  investigation  or enforcement  proceeding of a
criminal,  civil or  administrative  nature by any  investigative or enforcement
agency of any  government  (including any notice of qui tam action brought under
the Civil False Claims Act alleging any  irregularity,  misstatement or omission
arising under or relating to such Government Contract); and (3) to the Company's
knowledge,  other than nominal retainage,  no amount of money due to the Company

<PAGE>


been made to  withhold  or set off  money and the  Company  is  entitled  to all
progress payments received with respect thereto.

                           (v)  Neither  the  Company  nor any of the  Company's
officers or any of the TG  Employees  has been  suspended  or  debarred  from or
determined  to be  ineligible  for bidding or  submitting  offers on  Government
Contracts, no such suspension,  debarment or ineligibility has been initiated or
determined  or, to the  Company's  knowledge,  overtly  threatened or noticed in
writing,  and,  to  the  Company's  knowledge,  the  consummation  of  the  Sale
Transaction will not result in any such  suspension,  debarment or ineligibility
(assuming that no such suspension,  debarment or ineligibility  will result from
the  identity,  nationality  or conduct of Buyer or of persons  associated  with
and/or controlling Buyer).

                           (vi) Except for such matters as could not  reasonably
be  expected,  individually  or in the  aggregate,  to result  in a TG  Business
Material  Adverse  Effect:  (1) all personal  property,  equipment  and fixtures
loaned,  bailed or  otherwise  furnished  to the  Company by or on behalf of the
United States  Government in connection  with the TG Business that are or should
be in  the  possession  of  the  Company  ("Customer-Furnished  Items"),  in the
aggregate, are in a good state of maintenance and repair (ordinary wear and tear
excepted),  have been  regularly and  appropriately  maintained  and repaired in
accordance with all contractual,  legal and regulatory  requirements and, unless
returned  to the United  States  Government,  will be in the  possession  of the
Company  on the  Closing  Date;  and (2)  the  Company  has  complied  with  its
obligations  relating  to the  Customer-Furnished  Items  and,  upon the  return
thereof,  would have no material  liability to the United States Government with
respect thereto.

                           (vii) The following terms, as used in this Agreement,
have the  following  meanings:  (1) "Bid" means any written offer by the Company

order or other procurement arrangement of any kind in writing, valued at $10,000
or more and relating to the TG Business (A) between the Company and (I) the U.S.
Government  (acting  on its own  behalf  or on  behalf  of  another  country  or
international organization), (II) any prime contractor of the U.S. Government or
(III) any subcontractor to a prime contractor of the U.S. Government but only in
any case where the contract between the Company and such subcontractor expressly
indicates  that  such  contract  with  the  Company  is  being  entered  into in
connection  with a  Government  Contract  under  which the  other  party to such
contract  with the  Company  is a  subcontractor,  or (B)  financed  by the U.S.

concerning  procurement;  and (3)  "U.S.  Government"  means the  United  States

                  (t)  Insurance.  The  Company has in full force and effect the
policies of fire,  liability,  title,  errors and  omissions  and other forms of
insurance  relating to the TG Business  listed on Schedule 3.1(t) of the Company
Disclosure  Schedules.  The Company is not in default  under any such  policies,
which  default  could  reasonably  be expected  to have a TG  Business  Material
Adverse Effect, and there is no material  inaccuracy in any application for such
policies.  Each of the Company's  activities and  operations  relating to the TG
Business  have been  conducted  in a manner  so as to  conform  in all  material
respects to the  applicable  provisions  of such  policies.  The Company has not
received  a notice of  cancellation  or non  renewal  with  respect  to any such
policy.  Schedule 3.1(t) of the Company's  Disclosure Schedule lists all pending
claims  relating  to the TG  Business  under any of such  policies  in excess of
$10,000 and timely notice has been given of all such claims.

                  (u) Transactions  with Affiliates.  Except as disclosed in any
of the Company SEC Filings and excluding the TG Employment Contracts,  there are
no contracts, agreements, arrangements or understandings of any kind between any
affiliate of the Company,  on the one hand, and the Company,  on the other hand,
other than any such contracts, agreements,  arrangements and understandings that
either  individually  or in the  aggregate  are de  minimis  in nature or do not
relate to the TG Business.

                  (v) Intellectual Property.

                           (i)  The  Company  is  entitled  to  use  all  of the
following  which are used in or necessary  for the conduct of the TG Business as
currently conducted, namely: (1) trademarks,  logos, service marks, trade names,
internet domain names, designs, slogans, and general intangibles of like nature,
together  with  all  goodwill  related  to  the  foregoing  (collectively,   the
"Trademarks"),  (2) patents and patent applications,  (3) copyrights  (including
any  registrations,  renewals and  applications  for any of the foregoing),  (4)
software,  (5)  technology,   and  (6)  trade  secrets  and  other  confidential
information,  know how, proprietary  processes,  formulae,  algorithms,  models,
methodologies  and inventions  (collectively,  the "Trade Secrets" and, together
with items (1) through (5) above, the "Intellectual  Property"),  the absence of
which could, individually or in the aggregate,  reasonably be expected to have a
TG Business Material Adverse Effect.

                           (ii)  Schedule  3.1(v)  of  the  Company   Disclosure
Schedules sets forth,  for the  Intellectual  Property  owned by the Company,  a
complete  and  accurate  list of all U.S.  and  foreign  (1)  patents and patent
applications,   (2)  registrations  of  Trademarks  (including  internet  domain
registrations)   and   applications;   and  (3)  copyright   registrations   and
applications  (collectively,  the "Registered Intellectual Property").  Schedule
3.1(v)  sets  forth a  complete  and  accurate  list of all  license  agreements
relating to the TG Business (except for end user license and support/maintenance
agreements entered into in the

                                      -22-

<PAGE>


ordinary course of business (the "User  Agreements"))  granting any right to use
or practice any  Intellectual  Property,  whether the Company is the licensee or
licensor  thereunder,  and any written settlements  relating to any Intellectual
Property to which the Company is a party or otherwise bound  (collectively,  the
"License Agreements"),  indicating for each the title, the parties, and the date
executed.

                           (iii)  Except  for the User  Agreements  and  License
Agreements, to the Company's knowledge, (1) the Company has the right to use the
Intellectual  Property free and clear of all liens and obligations and (2) after
the Closing,  Buyer shall have the right to use the  Intellectual  Property free
and clear of all liens and  obligations  subject to the User  Agreements and the
License Agreements.

                           (iv)  The   Registered   Intellectual   Property   is
subsisting  and has not  been  canceled,  expired,  or  abandoned,  and,  to the
Company's knowledge,  the Registered Intellectual Property is valid. There is no
pending  or,  to  the  Company's  knowledge,   overtly  threatened   opposition,
interference  or  cancellation  proceeding  before  any  court  or  registration
authority in any jurisdiction against the Registered Intellectual Property.

                           (v) To the Company's knowledge, the conduct of the TG
Business as currently conducted does not infringe upon any intellectual property
rights  owned or  controlled  by any third  party.  There are no claims or suits
pending or, to the Company's knowledge,  overtly threatened, and the Company has
not  received any notice of a third party claim or suit,  (1) alleging  that its
activities with respect to any Intellectual  Property,  or the conduct of the TG
Business,  infringes upon, violates,  or constitutes the unauthorized use of the
intellectual  property  rights  of  any  third  party,  or (2)  challenging  the
ownership, use, validity or enforceability of any Intellectual Property.

                           (vi) There are no  settlements,  forbearances to sue,
consents,  judgments,  or  orders  to which  the  Company  is a party  which (1)
restrict the Company's rights to use any Intellectual Property, (2) restrict the
TG  Business  in order to  accommodate  a third  party's  intellectual  property
rights, or (3) permit third parties to use any Intellectual  Property used in or
necessary  for the conduct of the TG  Business.  The Company has not licensed or
sublicensed its rights in any material Intellectual Property other than pursuant
to the  User  Agreements  and/or  the  License  Agreements,  and  no  royalties,
honoraria  or other fees are  payable by the  Company for its use of or right to
use any Intellectual Property, except pursuant to the License Agreements. To the
Company's knowledge, the License Agreements are valid and binding obligations of
all parties  thereto,  enforceable in accordance  with their terms,  subject to,
bankruptcy,  insolvency and similar laws affecting  creditors' rights and to the
discretionary  nature of equitable  remedies,  and, to the Company's  knowledge,
there  exists no event or  condition  which will result in a violation or breach
of,  or  constitute  (with or  without  due  notice  or lapse of time or both) a
default by any party under, any such License  Agreement which violation,  breach
or default could,

                                      -23-

<PAGE>


individually  or in the aggregate,  reasonably be expected to have a TG Business
Material Adverse Effect.

                           (vii)   All   material   Trade   Secrets   and  other
confidential  Intellectual  Property  have  been  maintained  in  confidence  in
accordance  with  protection  procedures  customarily  used in the  industry  to
protect  rights of like  importance,  but not less  than  reasonable  care.  All
current  members of management  and key personnel of the TG Business,  including
all current employees,  agents,  consultants and independent contractors (except
for any  independent  contractors  which are parties to License  Agreements) who
have contributed to or participated in the conception or development of material
Trade  Secrets or other  confidential  Intellectual  Property the  disclosure of
which, individually or in the aggregate,  could reasonably be expected to have a
TG Business  Material  Adverse  Effect  (collectively  "Personnel"),  and to the
Company's  knowledge  all former  Personnel,  have executed and delivered to the
Company an employment or a  nondisclosure  agreement  restricting  such person's
right to disclose Trade Secrets and other confidential Intellectual Property. To
the  Company's  knowledge,  no party  to any  nondisclosure  agreement  with the
Company  relating  to any  Trade  Secrets  or  other  confidential  Intellectual
Property  is in breach or default  thereof.  All current  Personnel,  and to the
Company's  knowledge  all  former  Personnel,  either  (i) have been  party to a
"work-for-hire"  or  other  arrangement  or  agreement  with  the  Company,   in
accordance  with all  applicable  laws,  that has  accorded  the  Company  full,
effective,  exclusive  ownership of all tangible and intangible property thereby
arising in the course of their  employment  by the Company or (ii) have executed
appropriate  instruments  of assignment in favor of the Company as assignee that
have  conveyed to the Company full,  effective  and  exclusive  ownership of all
tangible and intangible  property  arising in the course of their  employment by
the Company excepting,  in the case of either subclause (i) or (ii) above, where
the  failure  of the  statement  made in such  subclause  to be true  could not,
individually  or in the aggregate,  reasonably be expected to have a TG Business
Material Adverse Effect. No current Personnel, and to the Company's knowledge no
former  Personnel,  have a  meritorious  claim against the Company in connection
with such person's  involvement  in the  conception or  development of any Trade
Secret or other Intellectual  Property and no such claim has been asserted or is
overtly  threatened.  None of the current  officers and employees of the Company
has any patents issued or applications pending for any device,  process,  design
or invention of any kind now used or needed by the Company in the furtherance of
the TG Business,  which  patents or  applications  have not been assigned to the
Company  under an  assignment  duly  recorded  in the United  States  Patent and
Trademark  Office or other  appropriate  Governmental  Entity in the case of any
foreign patents or patent applications.

                           (viii)  To the  knowledge  of the  Company,  no third
party is misappropriating,  infringing,  diluting, or violating any Intellectual
Property,  and no such claims have been  brought  against any third party by the
Company.

                           (ix) The  consummation of the Sale  Transaction  will
not (1)  result  in the loss or  impairment  of the  Company's  right to use any
Intellectual Property, nor (2) require the consent of any Governmental Entity or
third party in respect of any Intellectual  Property,  which loss or impairment,
or the failure to obtain which consent, could, individually or in the aggregate,
reasonably be expected to have a TG Business Material Adverse Effect.

                           (x) To the  extent  used  in  accordance  with  their
intended  purpose  as set forth in any  manuals  or  materials  (as  amended  or
supplemented)  delivered  in  connection  therewith,  all  of the  products,  as
upgraded to be Year 2000 Compliant (as defined below in this clause (x)), of the
Company  used in or  necessary  for the conduct of the TG Business and listed as
Included Assets (including products currently under development) will, after the
Closing,  except as could not,  individually or in the aggregate,  reasonably be
expected to have a TG  Business  Material  Adverse  Effect,  accurately  record,
store,  process,  calculate and present calendar dates falling on and after (and
if applicable,  spans of time  including)  January 1, 2000, and will  accurately
calculate  any  information  dependent  on or relating to such dates in the same
manner, and with the same functionality, data integrity and performance, as such
products  record,  store,  process,  calculate and present  calendar dates on or
before December 31, 1999, or calculate any information  dependent on or relating
to such dates (collectively,  "Year 2000 Compliant"). All of the products of the
Company  used in or  necessary  for the conduct of the TG Business and listed as
Included Assets (i) will, after the Closing,  except as could not,  individually
or in the  aggregate,  reasonably  be expected  to have a TG  Business  Material
Adverse  Effect,  lose no  functionality  with  respect to the  introduction  of
records  containing  dates  falling on or after January 1, 2000 and (ii) will be
operable  without error with other products used and  distributed by the Company
that may deliver  records to the products of the Company or receive records from
the products of the Company,  or interact with the  products,  including but not
limited to back up and archived data, provided that such other products are also
Year 2000 Compliant. Schedule 3.1(x) of the Company Disclosure Schedule contains
a true and correct  statement of the extent to which the  internal  computer and
technology products and systems used in the TG Business are Year 2000 Compliant.
The Company has taken all actions  represented  in such  statement  to have been
taken by it.

                  (w) Customs.  All goods imported into the United States or any
other country in connection  with the TG Business  (the  "Imported  Goods") have
been properly valued and classified in accordance  with applicable  tariff laws,
rules and regulations,  and all proper duties, tariffs or excise taxes have been
paid with  respect to the  Imported  Goods.  No  penalties  have been  assessed,
asserted or claimed with respect to any Imported Goods.  All Imported Goods have
been properly marked as to country of origin, content and material.

provisions) a complete and accurate list of the customers of the TG Business who
have purchased  products or services from the Company during the Company's prior
fiscal year or any interim  period from the end of the  Company's  prior  fiscal

actual or overtly threatened  termination,  cancellation or material  limitation
of, or any material  modification  or material change to the  configuration  of,
orders contained in outstanding backlog for the TG Business as of June 25, 1999,
as set forth in Schedule  3.1(x)(i).  Each of the  customers  listed on Schedule
3.1(w)(i)  has purchased  products or services in the TG Business  pursuant to a

Schedules  contains a complete and accurate list of all suppliers of significant
materials or services to the Company in connection with the TG Business.  To the

suppliers listed on Schedule 3.1(x)(ii).

                  (y)  Product  Warranties;  Defects;  Liability.  Each  product
manufactured,  sold,  leased, or delivered by the Company has been in conformity
with  all  applicable  contractual  commitments  and  all  express  and  implied
warranties,  and the Company does not have any liability  (and, to the Company's
knowledge,  there is no basis for any present or future action, suit proceeding,
hearing,  investigation,  charge, complaint,  claim, or demand against it giving
rise to any  liability)  for  replacement  or repair thereof or other damages in
connection therewith, except where any such non-conformity or any such liability
could not, individually or in the aggregate, reasonably be expected to have a TG
Business  Material  Adverse Effect.  No product  manufactured,  sold,  leased or
delivered by the Company in the ordinary course of the TG Business is subject to
any guaranty,  warranty or other indemnity beyond the applicable  standard terms
and  conditions of sale or lease or beyond that implied or imposed by applicable
law.  Schedule  3.1(y)  includes  copies  of the  Company's  standard  terms and
conditions of sale or lease relating to the TG Business.

                  (z)  Sufficiency of Included  Assets.  As of the Closing,  the
Included  Assets,  together  with the  Intellectual  Property  licensed to Buyer

         SECTION 3.2  Representations  and  Warranties  of Buyer.  Buyer  hereby
represents and warrants to the Company as follows:

Buyer.  Buyer has the requisite  corporate power and authority and any necessary
governmental  approvals to own,  operate or lease its properties and to carry on
its  business as it is now being  conducted,  except  where the failure to be so
organized,  existing and in good  standing or to have such power,  authority and
governmental  approvals could not, individually or in the aggregate,  reasonably
be expected to have a Buyer Material  Adverse  Effect.  The term "Buyer Material
Adverse  Effect"  means  any  material  adverse  change  in or effect on (i) the
business,  results of operations or condition  (financial or other) of Buyer and
its subsidiaries taken as a whole or (ii) the ability of Buyer to consummate the
Sale Transaction on or before the Terminal Date (a Buyer Material Adverse Effect
of the kind included in this clause (ii) being referred to as a "Buyer  Material
Adverse Consummation Effect").

                  (b)  Certificate  of  Incorporation  and  By-Laws.  Buyer  has
furnished  to the Company a complete  and  correct  copy of its  Certificate  of
Incorporation and By-Laws as currently in effect and the corresponding corporate
documents of MAESI.  Buyer is not in violation of any of the  provisions of such
Certificate of  Incorporation or By-Laws and MAESI is not in violation of any of
the provisions of such corresponding corporate documents.

                  (c) Authority  Relative to Agreement.  Buyer has all necessary
corporate  power and  authority  to enter into this  Agreement,  to perform  its
obligations  under this  Agreement and to consummate the Sale  Transaction.  The
execution,  delivery  and  performance  of  this  Agreement  by  Buyer  and  the
consummation  by  Buyer of the  Sale  Transaction  have  been  duly and  validly
authorized by all necessary  corporate action on the part of Buyer, and no other
corporate  proceedings  on the part of  Buyer  are  necessary  to  authorize  or
consummate  the Sale  Transaction.  This  Agreement  has been duly  executed and
delivered by Buyer and,  assuming due  authorization,  execution and delivery by
the  Company,  constitutes  a  legal,  valid  and  binding  obligation  of Buyer
enforceable against Buyer in accordance with its terms.

                  (d) No Conflict; Required Filings and Consents.

                           (i) The execution,  delivery and  performance of this
Agreement  by Buyer does not and will not:  (1)  conflict  with or  violate  the
Certificate  of  Incorporation  or  By-Laws  of  Buyer;  (2)  assuming  that all
consents, approvals and authorizations contemplated

                                      -27-

have been made and all  notification  periods  referred to in such  Section have
expired, conflict with or violate any law, rule, regulation,  order, judgment or
decree  applicable  to Buyer or by which  Buyer or its  properties  are bound or
affected;  or (3) result in any breach or violation  of or  constitute a default
(or an event which with notice or lapse of time or both could  become a default)
or result in the loss of a material  benefit under, or give rise to any right of
termination,  amendment,  acceleration  or  cancellation  of,  or  result in the
creation of any lien,  security  interest,  change or  encumbrance on any of the
properties or assets of Buyer pursuant to, any note, bond, mortgage,  indenture,
contract, lease, license, permit, franchise or other instrument or obligation to
which Buyer is a party or by which Buyer or any of properties or assets of Buyer
is bound or affected,  except,  in the case of clauses (2) and (3), for any such
conflicts,  violations, breaches, defaults or other occurrences which could not,
individually  or in the  aggregate,  reasonably be expected to result in a Buyer
Material Adverse Effect.

                           (ii) The execution,  delivery and performance of this
Agreement by Buyer and the  consummation of the Sale Transaction by Buyer do not
and will not require any consent,  approval,  authorization or permit of, action
by, filing with or notification  to, any  Governmental  Entity,  except for: (1)
applicable  filings under the  Hart-Scott  Act and the  Exon-Florio  Act and the
expiration  of the waiting  periods under those Acts;  (2)  clearance  under the
Federal rules and regulations  referred to in Section 5.1(d); and (3) such other
Requisite  Governmental  Approvals as shall have been  specified by Buyer to the
Company in writing prior to the date of this Agreement.

                  (e) Information Supplied.  None of the information supplied or
to be  supplied  by or on behalf of Buyer in writing or  otherwise  approved  by
Buyer for inclusion in the Proxy  Statement will contain,  at the date the Proxy
Statement is first mailed to the  Company's  shareholders  or at the time of the
Shareholders  Meeting,  any statement  which, in the light of the  circumstances
under which such  statement is made, is false or misleading  with respect to any
material fact, or omit to state any material fact necessary in order to make the
statements therein not false or misleading or necessary to correct any statement
in any earlier  communication  with respect to the solicitation of any proxy for
the Shareholders Meeting or any amendment or supplement thereto.

                  (f) Absence of Certain  Changes or Events.  Since December 31,
1998, there has not been any change,  event or development in or affecting Buyer
that,  individually  or in the aggregate,  constituted,  or could  reasonably be
expected to have, a Buyer Material Adverse Consummation Effect.

                  (g)  Absence  of  Litigation.  There  are  no  suits,  claims,
actions,  proceedings or  investigations  pending or, to the knowledge of Buyer,
overtly threatened  against Buyer or any of its subsidiaries,  or any properties
of Buyer or any of its subsidiaries, before any

                                      -28-

court, arbitrator or Governmental Entity that, individually or in the aggregate,
could  reasonably be expected to have a Buyer Material  Adverse Effect.  Neither
Buyer nor any of its  subsidiaries  nor any of their  respective  properties  or
assets is or are  subject  to any order,  writ,  judgment,  injunction,  decree,
determination or award having,  or which could reasonably be expected to have, a
Buyer Material Adverse Consummation Effect.

                  (h) Financing.  Buyer has and will provide the funds necessary
to  consummate  the  Sale  Transaction  in  accordance  with  the  terms of this
Agreement.  The  Included  Assets  will not be used to secure  any  indebtedness
incurred to provide such funds.

         SECTION 4.2  Shareholders  Meeting.  In connection with the requirement
that this  Agreement  and the Sale  Transaction  be  approved  by the  Company's
shareholders:  (a) the Company  shall take all action  necessary,  in accordance

By-Laws,  to convene a meeting of its shareholders (the "Shareholders  Meeting")
as soon as reasonably practicable after the

                                      -30-

<PAGE>


date of this  Agreement  to consider  and vote upon the adoption and approval of
this Agreement and the Sale Transaction,  and such other matters (if any) as the
Company may wish to submit for a separate vote at the Shareholders  Meeting; (b)
subject to clause (c) below, the Company,  through the Board, shall recommend to
its  shareholders  approval of this Agreement and the Sale  Transaction and such
recommendation  shall be included in the Proxy Statement;  and (c) the Board may
fail  to  make  such  recommendation,   or  withdraw,   modify  or  change  such
recommendation,  or take the  position  described  in  Section  6.1(g)(ii)  with
respect  to a tender  offer of the kind  therein  specified,  if and only if the
Board,  having been advised in writing by outside  counsel,  determines  in good
faith that the making of such  recommendation,  or the  failure to so  withdraw,
modify or change such  recommendation,  could constitute a breach of the Board's
fiduciary  duties to the Company's  shareholders  under  California law (but the
foregoing  shall not  entitle  the  Company  to delay or defer the  Shareholders
Meeting).

         SECTION  4.3  Preparation  of Proxy  Statement.  As soon as  reasonably
practicable following the date of this Agreement,  the Company shall prepare the
Proxy  Statement and,  following  approval by Buyer (which approval shall not be
reasonably  withheld),  shall file the Proxy Statement with the SEC. The Company
shall use its reasonable  commercial efforts to have the Proxy Statement cleared
by the SEC as promptly as practicable  after such filing.  The Company shall use
its reasonable  commercial  efforts to cause the Proxy Statement to be mailed to
the Company's  shareholders as promptly as practicable after the Proxy Statement
is cleared by the SEC. The Company and Buyer shall each correct any  information
provided by it for use in the Proxy  Statement  which shall have become false or
misleading.

         SECTION  4.4  Certain  Filings.  Promptly  following  the  date of this
Agreement:  (a) the Company and Buyer shall  prepare and file with the Antitrust
Authorities  all  documents and forms  required  under the  Hart-Scott  Act, and

efforts to obtain the timely  expiration of the waiting period applicable to the
Sale  Transaction  under the Hart-Scott Act; (b) Buyer shall make application to
the Committee on Foreign Investment in the United States ("CFIUS") under Section

thereafter with Buyer to achieve a favorable  review of the Sale  Transaction by
CFIUS;  and (c) Buyer  shall make the  applications  necessary  to  satisfy  the
condition set forth in Section 5.1(d) and the Company shall thereafter cooperate
with Buyer to satisfy  such  condition.  Where  required  or  appropriate  under
applicable  law,  any  person in  control  of Buyer may take any of the  actions
required to be taken by Buyer under this Section 4.4 but nothing  shall  relieve
Buyer of its  obligations  under this  Section  4.4 with  respect to any actions
required by this Section 4.4.

         SECTION 4.5 Access to Information.

                  (a) The Company:  (i) shall,  and shall cause its auditors and
other  agents  to,  afford  the  officers,  auditors  and other  agents of Buyer
reasonable  access at all reasonable  times (during normal  business hours so as
not to  unduly  or  unreasonably  interfere  with the TG  Business  or any other
business  of  the  Company)  to  its  senior   officers,   agents,   independent
accountants,  properties,  offices  and  other  facilities  involved  in  the TG
Business and (subject to restrictions  imposed by applicable law or by contract)
to all books and records  (including all Returns,  and the work papers and other
documents  of the  Company's  independent  accountants),  and to all  financial,
operating  and  other  data and  information,  in each case  relating  to the TG
Business,  the Included Assets and the Included  Liabilities,  as Buyer, through
its officers,  may from time to time reasonably  request (including all internal
financial and  operating  reports and  results);  (ii) shall make  available its
senior  officers,  its  independent  accountants  and (subject to all applicable
privileges,  which shall not be deemed waived) its outside counsel, in each case
upon  reasonable  prior notice and during normal  business hours, to confer on a
regular  basis with the  appropriate  officers  of Buyer  regarding  the ongoing
operations  of  the  TG  Business,   the   implementation  of  the  transactions
contemplated  by this Agreement and other matters  reasonably  related  thereto;
(iii) shall,  promptly after it has,  consistently into its customary practices,
closed its books for accounting and financial reporting purposes with respect to
each completed  calendar month prior to the Closing (excluding the month covered
by the unaudited financial  statements referred to in Section 2.2(ix)),  furnish
to Buyer the  unaudited  balance  sheet of the TG Business as of the last day of
such month, and the related unaudited  statements of earnings and cash flows for
the year-to-date  period then ended, in each case prepared on a basis consistent
with the basis of  preparation  of the TG  Interim  Financials;  and (iv)  shall
promptly  notify Buyer of any change by the Company in its  accounting  methods,
principles  or  practices  (whether  or not  required  by  changes  in  GAAP  or
recommended by the Company's independent accountants). No investigation pursuant
to this Section  4.5(a) shall affect any  representations  or  warranties of the
Parties  made in this  Agreement or the  conditions  to the  obligations  of the
Parties under this Agreement.

                  (b) Buyer  shall hold  information  it  receives  pursuant  to
Section  4.5(a)  which is nonpublic in  confidence  and shall not disclose  such
information to any third party without the written consent of the Company.  Such
information  shall be subject to the  Confidentiality  Agreement dated March 31,
1999 between the Company and Marconi (the "Confidentiality Agreement").

         SECTION 4.6 Solicitations.

                  (a)  Offers  for  the TG  Business.  The  Company  shall  not,
directly  or  indirectly,  through  any  officer,  director  or agent,  solicit,
initiate or encourage the submission of any

                                      -32-

<PAGE>


proposal or offer from any person  relating to (and limited to) any  acquisition
or purchase of all or any material portion (other than inventory in the ordinary
course) of the assets of, or any equity interest in, the TG Business or solicit,
participate in or initiate any negotiations  regarding,  or furnish to any other
person any information with respect to, or otherwise  cooperate in any way with,
or assist or participate in,  facilitate or encourage,  any effort or attempt by
any other person to do or seek to do any of the foregoing, and all efforts being
conducted  by or on  behalf  of the  Company  on the date of this  Agreement  to
solicit purchasers of the TG Business shall be discontinued forthwith. Also, the
Company  shall not release any third party from,  or waive any provision of, any
confidentiality or standstill  agreement to which the Company is a party insofar
as such agreement relates to the TG Business.

                  (b) Solicited Offers for the Company or its Other  Businesses.
Nothing in this Agreement shall preclude the Company from continuing its efforts
to sell either the Company as an entirety or the Company's component  businesses
other than the TG Business pursuant to a merger, consolidation,  share exchange,
business  combination,  tender or exchange  offer,  asset  acquisition  or other
similar transaction (a "Non-TG Transaction");  provided,  however, that: (i) the
Company  shall  inform  all third  parties  from which it  solicits  an offer or
proposal  for, and with which it  negotiates,  any Non-TG  Transaction  that the
Company is bound by the provisions of this Agreement,  including Section 4.6(a);
(ii) the Company shall not solicit,  initiate or encourage  the  submission of a
proposal for, or enter into any agreement providing for, a Non-TG Transaction on
terms that would  prevent the Company from  consummating  the Sale  Transaction;
(iii) the Company shall not solicit,  initiate or encourage the  submission of a
proposal for, or enter into any agreement  providing  for, a Non-TG  Transaction
pursuant to which control of the Company as an entirety  would be acquired prior
to the  consummation  of the Sale  Transaction  unless the terms of such  Non-TG
Transaction  require the acquiror to acknowledge the existence of, and cause the
Company to comply with its  obligations  under,  this  Agreement  and the Escrow
Agreement;  and (iv) all efforts being  conducted by or on behalf of the Company
on the date of this  Agreement to solicit,  initiate or  encourage  any proposal
inconsistent  with this Section 4.6(b) shall be discontinued  forthwith and each
of the  parties  to the  Other  Confidentiality  Agreements  shall  promptly  be
informed  that the  Company  has  agreed  with  Buyer to  cease  soliciting  and
accepting any proposals  involving the direct or indirect  acquisition of the TG
Business.

                  (c) Unsolicited  Inconsistent Offers for the Company.  Nothing
in  Sections  4.6(a)  or (b) shall  prohibit  the  Company  from  informing  its
shareholders,  and taking action under clause (c) of Section 4.2, if it receives
an unsolicited  written bona-fide proposal made to the Company after the date of
this  Agreement to consummate a transaction  that would  (directly or through an
acquisition of the Company as an entirety)  include the TG Business and preclude
the Company from consummating the Sale

                                      -33-

<PAGE>


Transaction  provided  that:  (i)  the  Company  gives  Buyer,  as  promptly  as
practicable,  written notice of the receipt of any such proposal together with a
copy of such  proposal or an accurate  and  reasonably  detailed  summary of the
material  terms  thereof and a statement of the identity of the  proponent;  and
(ii) the  Company  does  not,  directly  or  indirectly,  through  any  officer,
director, agent or otherwise,  furnish information to, or enter into discussions
or  negotiations  with,  such other bidder until after the  shareholders  of the
Company have voted on the Sale Transaction and then only if such vote shall fail
to approve the Sale Transaction.

         SECTION 4.7 Indemnification.

                  (a)  General  Indemnification  by  the  Company.  The  Company
covenants and agrees, from and after the Closing, to indemnify,  defend, protect
and hold  harmless  Buyer and its  respective  officers,  directors,  employees,

and, collectively, the "Buyer Indemnified Parties") from, against and in respect
of all liabilities, losses, claims, damages, business disruption,  consequential
damages,   punitive  damages,   causes  of  action,   lawsuits,   administrative

assessments,  judgments,  settlement payments,  deficiencies,  penalties, fines,
interest payable to third persons and reasonable  costs and expenses  (including
without  limitation   reasonable   attorneys'  fees  and  other   disbursements)
(collectively,  "Damages")  suffered,  sustained,  incurred or paid by the Buyer
Indemnified  Parties in  connection  with,  resulting  from or  arising  out of,
directly or indirectly:  (i) any inaccuracy or breach of any  representation  or
warranty of the Company set forth in this Agreement (as qualified by the Company
Disclosure Schedules) or any certificate delivered by or on behalf of Company at
the Closing; (ii) any nonfulfillment of any covenant or agreement of the Company
in this Agreement;  (iii) any Excluded  Liabilities;  or (iv) any liabilities of
the Company that are not Included Liabilities.

                  (b) General  Indemnification  by Buyer.  Buyer  covenants  and
agrees,  from and after the Closing,  to indemnify,  defend and protect and hold
harmless the Company and its respective officers, directors, employees, assigns,
successors  and  affiliates  (individually  a "Company  Indemnified  Party" and,
collectively, the "Company Indemnified Parties") from, against and in respect of
all Damages  suffered,  sustained,  incurred or paid by the Company  Indemnified
Parties  in  connection  with,  resulting  from  or  arising  out,  directly  or
indirectly:  (i) any inaccuracy or breach of any  representation  or warranty of
Buyer set forth in this Agreement or any  certificate  delivered by or on behalf
of Buyer at the Closing; (ii) any nonfulfillment of any covenant or agreement of

                                      -34-

<PAGE>


TG Business  after the Closing;  or (vi) any  liabilities  of Buyer that are not
Excluded Liabilities.

                  (c)  Limitations  and  Expiration.   Notwithstanding  Sections
4.7(a) and (b):

                           (i) The  aggregate  amount  for which the  Company is
required to indemnify the Buyer Indemnified Parties under this Section 4.7 shall
not exceed the Escrow Fund;  provided,  however,  that this limitation shall not
apply to, and the Buyer Indemnified  Parties shall not be obligated to apply any
claims against the Escrow Fund with respect to, the Company's  liability for (i)
Damages  arising out of any  liabilities  referenced in Sections  4.7(a)(iii) or
(iv);  (ii) any indemnity under Section 4.8(b) or any Damages arising out of any

contained in this Agreement (as qualified by the Company  Disclosure  Schedules)
or in any  certificate  delivered by or on behalf of Company at the Closing;  or
(iv) any adjustment to the Estimated  Consideration  under Sections 1.3, and 1.4
(it being  understood  that any matter with respect to which any such adjustment
is made  under  Section  1.4  shall  not  also be  considered  a  breach  of any
representation or warranty of Company contained in this Agreement).

                           (ii) The indemnification obligations of Company under
this  Section  4.7  shall  terminate  at the date that is the later of the dates
specified in clause (A) and (B) of this Section 4.7(c)(ii):

                                    (A)   (1)  Except  as  to   representations,

4.7(c)(ii),  and subject to clause (B) of this Section  4.7(c)(ii),  the Initial
Release Date as defined in Section 9(a) of the Escrow  Agreement  (the  "Initial

this  Agreement,  no Claim (as defined in Section  4.7(d) below) with respect to
any of the matters  referenced in this clause  (A)(1) shall be effective  unless
Buyer  gives the  Company a Claim  Notice (as  defined in Section  4.7(d)) on or
prior to the Initial Release Date; or

                                          (2) With  respect to the  covenants of
the Company set forth in Section 4.8, the  expiration  of all relevant  Federal,
state or foreign statute of limitation (including extensions thereof); or

                                          (3)   With    respect   to    Excluded
Liabilities or any liabilities of the Company that are not Included Liabilities,

indemnification of the Company shall survive forever; or

                                      -35-

<PAGE>


                                    (B)  Notwithstanding   clause  (A)  of  this
Section 4.7(c)(ii),  as to any Claim for which a Claim Notice has been delivered
to the Company as of the relevant  date  described in clause (A) of this Section
4.7(c)(ii) (all such claims, and the claims referred to in Section  4.7(c)(iii),
being  referred to as "Pending  Claims"),  the final  resolution of such Pending
Claim  (notwithstanding  the earlier  occurrence of the date applicable  thereto
under Section 4.7(c)(ii)(A) above).

                           (iii) The indemnification  obligations of Buyer shall
terminate at the date that is the later of (A) the Initial Release Date,  except
that  the  indemnification  obligations  of Buyer to the  Company  set  forth in
Section  4.7(b)(iii),  (iv),  (v) and (vi) and with respect to the  covenants of
Buyer set forth in Section 4.8 shall terminate on the expiration of all relevant
Federal,  state or foreign statute of limitations (including extensions thereof)
and (B) the resolution of all Pending Claims against Buyer under Section 4.7(b).

                           (iv) Notwithstanding anything to the contrary in this
Agreement:  (I) no Buyer Indemnified Party shall be entitled to  indemnification
under this  Agreement  unless and until the sum of all  otherwise  indemnifiable
amounts payable to all the Buyer Indemnified  Parties together exceeds $250,000,
in which case,  subject to the other  provisions of this  Agreement,  the amount
indemnifiable  shall be the entire  aggregate  amount due,  including  the first
$250,000;   and  (II)  no  Company   Indemnified  Party  shall  be  entitled  to
indemnification  under this Agreement  unless and until the sum of all otherwise
indemnifiable  amounts payable to all the Company  Indemnified  Parties together
exceeds  $250,000,  in which  case,  subject  to the  other  provisions  of this
Agreement,  the amount  indemnifiable  shall be the entire aggregate amount due,
including the first $250,000.  The foregoing limitations of clauses (I) and (II)
shall not apply to the indemnification  obligations of either Party with respect
to their respective  covenants set forth in Section 4.8 and the  indemnification
obligations of Company set forth in Section  4.7(c)(ii)(A)(3) and shall also not
apply to the  obligations of either Party with respect to the matters  specified
in Section 4.7(a)(iii)(iv),  Section 4.7(b)(v) or (vi), Section 4.7(c)(i)(iv) or
Section 6.2.

                           (v) The aggregate  amount for which Buyer is required
to indemnify  the Company  Indemnified  Parties under this Section 4.7 shall not
exceed $1,000,000;  provided,  however,  that this limitation shall not apply to
Buyer's liability for: (i) Damages arising out of any liabilities  referenced in
Sections 4.7(b)(iii), (iv), (v) or (vi); (ii) any indemnity under Section 4.8(c)
or any Damages  arising out of any breaches of the  covenants of Buyer set forth
in Section 4.8; or (iii) Damages based on fraud or willful breaches by Buyer, or
any  of  its   affiliates  or  agents  on  behalf  of  Buyer,   of  any  of  its
representations or warranties  contained in this Agreement or in any certificate
delivered by or on behalf of Buyer at the Closing.

                  (d)  Indemnification  Procedures.  All claims or  demands  for
indemnification under this Section 4.7 ("Claims") shall be asserted and resolved
as follows:

                           (i) In the event that any Company  Indemnified  Party
or Buyer  Indemnified  Party (an  "Indemnified  Party") has a Claim  against any
party obligated to provide indemnification pursuant to Section 4.7(a) or (b) (an
"Indemnifying  Party") which does not involve a Claim being asserted  against or
sought to be  collected  by a third  party,  the  Indemnified  Party  shall with
reasonable  promptness give written notice (the "Claim Notice") of such Claim to
the  Indemnifying  Party,  with  a copy  to the  Escrow  Agent,  if  applicable,
specifying  the  nature of such  Claim and the  amount or the  estimated  amount
thereof to the extent then feasible.  If the Indemnifying  Party does not notify
in writing  the  Indemnified  Party  within  thirty  (30) days after the date of
delivery of the Claim Notice that the  Indemnifying  Party  disputes such Claim,
with a  statement  in  reasonable  detail (to enable  the  Indemnified  Party to
understand  the nature of the dispute) of the basis of such  position (a "Notice
of Objection"), a copy of which is delivered to the Escrow Agent, if applicable,
the  amount  of such  Claim  shall be  conclusively  deemed a  liability  of the
Indemnifying Party hereunder.  In case a Notice of Objection is delivered to the
Indemnified  Party in accordance  with this Section  4.7(d)(i),  the Indemnified
Party shall  respond in a written  statement to the Notice of  Objection  within
thirty (30) days and, for sixty (60) days thereafter,  the parties shall attempt
in good faith to resolve such dispute  (and, if the parties  should so agree,  a
memorandum  setting  forth such  agreement  shall be prepared and signed by both
parties).  If the parties do not resolve the dispute  within such sixty (60) day
period,  either party may demand  arbitration of the matter unless the amount of
the Damages is at issue in pending litigation with a third party, in which event
arbitration  shall not be  commenced  until the  amount is  ascertained  or both
parties agree to arbitration. Any arbitration under this Section 4.7(d) shall be
conducted in accordance with Section 7.6.

                           (ii)     (A) In the  event  that any  Claim for which
the  Indemnifying  Party would be liable to an  Indemnified  Party  hereunder is
asserted against an Indemnified  Party by a third party (a "Third Party Claim"),
the Indemnified  Party shall promptly deliver a Claim Notice to the Indemnifying
Party.  The  Indemnifying  Party  shall have  thirty  (30) days from the date of
delivery  of the Claim  Notice to notify the  Indemnified  Party (I) whether the
Indemnifying  Party disputes  liability to the Indemnified  Party hereunder with
respect to the Third Party Claim, and, if so, the basis for such a dispute,  and
(II) whether or not the Indemnifying Party desires, at the sole cost and expense
of the  Indemnifying  Party,  to defend against the Third Party Claim,  provided
that the Indemnified  Party, at the sole cost and expense,  is hereby authorized
(but not obligated) to file any motion, answer or other pleading and to take any
other  reasonable  action which the  Indemnified  Party shall deem  necessary or
appropriate to protect the Indemnified Party's interests.

                                      -37-

<PAGE>


                                    (B)  If the  Indemnifying  Party  elects  to
defend the  Indemnified  Party  against  such Third Party  Claim by  appropriate
proceedings, then, unless the Indemnified Party otherwise agrees in writing, the
Indemnifying Party may not settle any Third Party Claim (in whole or in part) if
such  Indemnified  Party desires to  participate  in, but not control,  any such
defense  or  settlement  the  Indemnified  Party  may do so at its sole cost and
expense.  If the Indemnifying  Party elects not to defend the Indemnified  Party
against a Third Party  Claim,  whether by failure of the  Indemnifying  Party to
give the Indemnified  Party timely notice as provided herein or otherwise,  then
the Indemnified Party, without waiving any rights against such party, may settle
or defend against such Third Party Claim in the Indemnified  Party's  reasonable
discretion  and the  Indemnified  Party shall be  entitled  to recover  from the
Indemnifying Party or the Escrow Fund, as provided in Section 4.7(e), the amount
of any settlement or judgment and, on an ongoing basis, all indemnifiable  costs
and expenses of the Indemnified Party with respect thereto.

                                    (C)  If  at  any  time,  in  the  reasonable
opinion of the Indemnified  Party,  notice of which shall be given in writing to
the Indemnifying Party, any Third Party Claim seeks material  prospective relief
which could have an adverse effect on any Indemnified  Party or the TG Business,
the Indemnified Party shall have the right to control or assume (as the case may
be) the defense of any such Third Party Claim and the amount of any  judgment or
settlement and the reasonable costs and expenses of defense shall be included as
part of the indemnification  obligations of the Indemnifying Party hereunder. If
the  Indemnified  Party elects to exercise such right,  the  Indemnifying  Party
shall have the right to  participate  in, but not  control,  the defense of such
Third Party Claim at the sole cost and expense of the Indemnifying Party.

                           (iii) The  Indemnified  Party shall  cooperate  fully
with the Indemnifying Party to defend Third Party Claims as reasonably requested
by the Indemnifying Party by, for example,  making relevant employees reasonably
available and providing  reasonable  access to documents and information  during
normal business hours and with prior notification.

                           (iv) Subject to Section 4.7(c),  nothing herein shall
be  deemed  to  prevent  the  Indemnified  Party  from  making a  Claim,  and an
Indemnified  Party  may make a Claim  hereunder,  for  potential  or  contingent
Damages;  provided,  however,  that  within  thirty (30) days of  notifying  the
Indemnifying  Party of such potential or contingent claim, the Indemnified Party
delivers to the  Indemnifying  Party a Claim Notice that sets forth the specific
basis for any such Claim.

                           (v) Subject to the provisions of Section 4.7(c),  the
Indemnified  Party's  failure to give  reasonably  prompt  notice as required by
Section  4.7(d) of any actual,  threatened or possible claim or demand which may
give  rise to a  right  of  indemnification  hereunder  shall  not  relieve  the
Indemnifying Party of any liability which the

                                      -38-

<PAGE>


Indemnifying  Party may have to the Indemnified Party unless the failure to give
such notice materially and adversely prejudiced the Indemnifying Party.

                           (vi) In the event of any  inconsistency  between  the
procedures  set forth in this  Section  4.7(d) and the  procedures  set forth in
Section 4.8 (relating to Taxes), Section 4.8 (relating to Taxes) shall control.

                  (e)  Escrow  Fund:  Appointment  of  Escrow  Agent;  Exclusive
Remedy.  The Company and Buyer hereby agree to the creation of an escrow fund to
satisfy  the  Company's  indemnification  obligations  to the Buyer  Indemnified
Parties  pursuant to the terms of this Section 4.7. The Company  shall be deemed
to have received and  deposited  with the Escrow Agent the Escrow Amount and all
interest  and  earnings  accruing on the Escrow  Amount  shall accrue to (and be
taxable  currently to) Company.  The Escrow Amount and all interest and earnings
thereon,  as  increased or decreased  from time to time in  accordance  with the
Escrow Agreement  (collectively,  the "Escrow Fund"),  and all claims or demands
for  payment out of the Escrow Fund shall be governed by the terms of the Escrow
Agreement.  The Company and Buyer hereby  appoint an Escrow Agent to  administer
the Escrow Fund.  The Company and Buyer shall each bear one half of the fees and
expenses of the Escrow Agent incurred in connection with the  establishment  and
maintenance  of the  Escrow  Fund.  The  Parties  agree  and  acknowledge  that,
notwithstanding any other provision of this Agreement,  payments from the Escrow
Fund  shall be the Buyer  Indemnified  Parties'  sole and  exclusive  remedy for
Damages for which the Company shall be liable under Section 4.7(a), and no Claim
may first be made once the  balance  in the Escrow  Fund has fallen to zero,  in
each case except as set forth in Section 4.7(c)(i).

                  (f) Survival of Representations, Warranties and Covenants. The
representations  and warranties of the Company shall survive the Closing,  shall
remain in effect  until,  and shall  (subject  to the final  sentence of Section
4.7(e)) expire in accordance with, Section  4.7(c)(ii).  The representations and
warranties of Buyer shall survive the Closing, shall remain in effect until, and
shall expire in accordance with, Section 4.7(c)(iii).

                  (g) Calculation of Losses. The amount of any Damages for which
indemnification  is provided  under this  Section 4.7 or Sections  4.8(b) or (c)
shall be net of any amounts  actually  recovered by the Indemnified  Party under
insurance  policies  with respect to such Damages and shall be (i)  increased to
take account of any net Tax cost incurred by the Indemnified  Party arising from
the receipt of indemnity  payments  hereunder (grossed up for such increase) and
(ii) reduced to take account of any net Tax benefit  realized by the Indemnified
Party arising from the  incurrence or payment of any such Damages,  in each case
calculated at the time of payment,  using the  characterization  described below
and assuming that all income and deductions bear (or relieve) Tax at an

                                      -39-

<PAGE>


effective  corporate rate based on the maximum marginal Federal rate and a state
rate of 7.0%,  taking into account the  deductibility (if then allowed) of state
tax from Federal taxable income. Any indemnity payment under this Section 4.7 or
Sections  4.8(b)  or (c)  shall be  treated  as an  adjustment  to the  Adjusted
Consideration for Tax purposes, or as settlement of an obligation intended to be
retained by the Company  although  paid by Buyer,  unless a final  determination
(which shall  include the  execution  of a Form 870-AD or  successor  form) with
respect  to the  Indemnified  Party  or any of its  affiliates  causes  any such
payment not to be treated as an  adjustment  to the Adjusted  Consideration  for
United States Federal income tax purposes.  If any Tax Agency asserts in writing
during the  examination of any Return of Buyer or the Company that any indemnity
payment should be  characterized  other than as provided in this Section 4.7(g),
the Party that receives the proposed  recharacterization  (the "Affected Party")
shall promptly notify the other Party (the "Consulted Party") in writing, with a
copy of the  proposed  recharacterization.  The  Affected  Party may control any
proceedings involving the proposed  recharacterization  but (1) shall resist, in
good faith and by appropriate proceedings, the proposed recharacterization,  (2)
shall  provide  the  Consulted   Party  with  copies  of  the  portions  of  all
communications  from the  relevant  Tax  Agency  and all  proposed  filings  and
submissions  regarding the proposed  recharacterization,  (3) shall consult with
the  Consulted  Party  regarding  the conduct of the contest,  and (4) shall not
settle or concede  the  proposed  recharacterization  without the consent of the
Consulted Party. If the Affected Party materially breaches its obligations under
the preceding sentence,  the Consulted Party may, in computing the amount of any
indemnity  payable  to the  Affected  Party,  continue  to treat  its  indemnity
payments as an adjustment to the Adjusted  Consideration  and not as provided in
any final determination made with respect to the Affected Party.

         SECTION 4.8 Tax  Matters.  The Company and Buyer  hereby  covenant  and
agree with respect to certain Tax matters as follows:

                  (a) Tax Treatment and Allocations.  Within sixty 60 days after
the date of this  Agreement,  Buyer  shall  provide  to the  Company a  schedule
setting forth the proposed allocation (the "Preliminary Allocation Schedule") of
the Estimated  Consideration to and among the Included Assets,  such Preliminary
Allocation  Schedule to be adjusted following the Closing Date to reflect events
occurring  between the date of this  Agreement and the Closing Date with a final
version  thereof (the  "Updated  Allocation  Schedule")  to be prepared by Buyer
within  35 days  after  the  Closing  Date.  Such  allocations  shall be made in
accordance  with  Section  1060 of the Tax  Code  and  any  applicable  Treasury
Regulations and shall also reflect an appropriate  allocation to Included Assets
subject to sales or other  transfer  taxes.  The Company shall be deemed to have
accepted the Updated Allocation  Schedule,  and it shall be deemed final, unless
the Company  provides written notice of disagreement to Buyer within thirty (30)
days of receipt of the Updated Allocation Schedule (the "Disagreement  Notice").
If the Company  provides a Disagreement  Notice,  the Parties shall negotiate in
good faith to resolve the  differences.

                                      -40-

<PAGE>


If the disagreements are not resolved within thirty (30) days of Buyer's receipt
of the Disagreement Notice, Buyer shall engage a national independent accounting
firm (the  "Accountant")  reasonably  acceptable  to the  Company to resolve the
difference.  The  Accountant  will be  requested  to  resolve  the  dispute  and
determine  the correct  allocation  in accord with  Section 1060 of the Tax Code
and,  within thirty (30) days of  engagement,  to issue its report in writing to
Buyer and the Company  (the  "Accountant  Report").  One half of the fees of the
Accountant  shall be borne by the  Company  and one half of such  fees  shall be
borne by Buyer.  Neither  Party shall take a position on any Return,  before any
Tax Agency or in any judicial  proceeding that is inconsistent  with the Updated
Allocation Schedule,  if final, or the Accountant Report,  except as required by
law.

                  (b) Returns.  The Company  shall prepare and file (or cause to
be prepared  and filed) on a timely  basis (to the extent not filed on or before
the date of this  Agreement)  all Returns for all taxable  periods  ending on or
before the Closing Date,  shall (subject to Section  4.8(i)) pay all Taxes shown
to be due on such Returns,  and shall indemnify and hold Buyer harmless against,
from and in respect of (i) all Taxes of the Company attributable to the Included
Assets or the  operation  of the TG  Business  (the "TG  Taxes") for all taxable
periods (or any portion thereof) which end on or before the Closing Date (except
to the extent such TG Taxes have been  included  in the  Adjusted  Closing  Date
Balance  Sheet);  (ii) all TG Taxes for any  taxable  period or periods  for all
members of any affiliated,  consolidated, combined or unitary group of which the
Company  is or has been a member  prior to the  Closing  Date;  and  (iii)  with
respect to any taxable  period  commencing  before the  Closing  Date and ending
after the Closing Date (a "Straddle  Period"),  all TG Taxes attributable to the
portion of the  Straddle  Period  prior to and  including  the Closing Date (the
"Pre-Closing  Period") (except to the extent such TG Taxes have been included in
the Adjusted  Closing Date Balance Sheet).  For purposes of this Agreement,  the
portion of any Tax which is the subject of this Section 4.8 that is attributable
to the  Pre-Closing  Period  shall  be (i) in the case of a Tax  (including  any
property  or ad  valorem  Tax) that is not based on net  income,  gross  income,
premiums  or gross  receipts,  the total  amount  of such Tax for the  period in
question multiplied by a fraction,  the numerator of which is the number of days
in the Pre-Closing  Period,  and the denominator of which is the total number of
days in such Straddle Period, and (ii) in the case of a Tax which is the subject
of this Section 4.8 that is based on any of net income,  gross income,  premiums
or gross  receipts,  the Tax that would be due with  respect to the  Pre-Closing
Period if such Pre-Closing  Period were a separate  taxable period,  except that
exemptions,  allowances,  deductions or credits that are calculated on an annual
basis (such as the deduction for  depreciation or capital  allowances)  shall be
apportioned on a per diem basis.  For purposes  hereof,  all Taxes which are the
subject of this  Section 4.8 arising  from the Sale  Transaction,  except as set
forth in  Section  4.8(i),  shall be  deemed  to be  Taxes  attributable  to the
Pre-Closing Period and shall be the responsibility of Company.

                                      -41-

<PAGE>


                  (c)  Indemnity;  Liability for Taxes.  Buyer shall prepare and
file (or cause to be prepared  and filed) on a timely  basis all Returns for all
taxable  periods  beginning after the Closing Date,  shall,  subject to Sections
4.8(d)  through  (f), pay all Taxes shown to be due on such  Returns,  and shall
indemnify and hold the Company harmless  against,  from and in respect of all TG
Taxes (i) for any taxable year or period  commencing after the Closing Date, and
(ii) for any Straddle Period,  other than Taxes  attributable to the Pre-Closing
Period.  The  principles of the first  sentence of Section 4.7(g) shall apply to
any indemnification payment by either Party to the other under this Section 4.8.

                  (d)  Refunds and  Credits.  All refunds or credits of TG Taxes
for or  attributable to taxable years or periods ending on or before the Closing
Date (or the Pre-Closing  Period, in the case of a Straddle Period) shall be for
the  account  of the  Company,  except to the  extent  such  refund or credit is
included in the  Adjusted  Closing Date Balance  Sheet.  Following  the Closing,
Buyer shall  forward (or cause to be  forwarded) to the Company any such refunds
or credits due to the Company pursuant to this Section 4.8 and the Company shall
forward (or cause to be  forwarded) to Buyer all refunds or credits due to Buyer
pursuant to this Section 4.8, in each case in accordance  with the provisions of
Section 4.8(f).

                  (e) Procedures Regarding Tax Changes.

                           (i) If an  audit  examination  of any  Return  of the
Company for any taxable period ending on or before the Closing Date shall result
(by  settlement  or  otherwise)  in any  adjustment  the  effect  of which is to
increase deductions,  losses or tax credits or decrease income, gains, premiums,
revenues or recapture of Tax credits ("Changes")  reflected on a Return of Buyer
for any taxable  period ending after the Closing Date,  the Company shall notify
Buyer and provide it with all  necessary  information  so that it can reflect on
the appropriate Return any appropriate Changes. If, as a result of such Changes,
Buyer or its  subsidiaries  enjoy a net Tax benefit (taking into account all Tax
effects) from an increase in deductions, losses or tax credits and/or a decrease
in income,  gains,  premiums,  revenues or recapture of tax credits  ("Buyer Tax
Benefits") for taxable periods ending after the Closing Date, Buyer shall pay to
Company  the amount of such Buyer Tax  Benefit  within  thirty (30) days of when
such Buyer Tax  Benefits  were  actually  realized by Buyer in  accordance  with
Section 4.8(f).

                           (ii) If an audit  examination  of any Tax  Return  of
Buyer or its subsidiaries for taxable period ending after the Closing Date shall
result (by  settlement or otherwise) in any Change  reflected on a Return of the
Company or its  subsidiaries  for any  taxable  periods  ending on or before the
Closing  Date,  Buyer  shall  notify  the  Company  and  provide it with all the
necessary information so that the Company can reflect any appropriate Changes on
its Return.  If, as a result of such  Changes,  the Company or its  subsidiaries
enjoy a net Tax benefit (taking into account all Tax effects) from an increase

                                      -42-

<PAGE>


in  deductions,  losses or tax credits  and/or a decrease in the income,  gains,
premiums, revenues, or recapture of tax credits the ("Company Tax Benefits") for
taxable  periods  ending on or before the Closing Date, the Company shall pay to
Buyer the amount of such  Company Tax Benefits  within  thirty (30) days of when
such  Company  Tax  Benefits  are  actually  realized  by  the  Company  or  its
subsidiary, in accordance with Section 4.8(f).

                  (f) Timing of Tax Benefit Payments. Any payments or refunds or
credits for Taxes, or any payment of Buyer Tax Benefits or Company Tax Benefits,
that are required to be paid under this  Agreement  shall be made within  thirty
(30)  business days of receipt of any refund or thirty (30) business days of the
actual realization of any tax benefit, as the case may be.

                  (g) Termination of Tax Sharing Agreements.  The Company hereby
agrees  that,  except for this  Agreement,  there are no, and as of the  Closing
there  will  be no,  obligations  of the  Company  relating  to the TG  Business
pursuant  to any tax  sharing  agreement  or any  similar  arrangement,  and any
further  obligations  that might  otherwise  have  existed  thereunder  shall be
extinguished as of the Closing.

                  (h) Conduct of Audits or other Procedural Matters.  Each Party
shall,  at its own expense,  control any audit or examination by any Tax Agency,
and have the right to  initiate  any claim for  refund or  amended  Returns  and
contest,  resolve and defend  against any  assessment,  notice of  deficiency or
other  adjustment or proposed  adjustment of Taxes (the  "Proceedings")  for any
taxable  period for which that Party is charged with payment or  indemnification
responsibility  under this Agreement.  Each Party shall promptly  forward to the
other all written notifications and other written communications  including,  if
applicable,  the  original  envelope  showing any  postmark,  for any Tax Agency
received by such Party or its affiliates relating to any liability for Taxes for
any  taxable  period  for which  such other  Party or any of its  affiliates  is
charged with sole payment or indemnification responsibility under this Agreement
and each  Indemnifying  Party shall  promptly  notify,  and consult  with,  each
Indemnified  Party  to any  action  it  proposes  to take  with  respect  to any
liability  for Taxes for which it is required to  indemnify  the other Party and
shall not enter into any  closing  agreement  or final  settlement  with any Tax
Agency with  respect to any such  liability  without the written  consent of the
Indemnified Parties,  which consent shall not be unreasonably  withheld.  In the
case of any Proceedings  relating to a Straddle Period, Buyer shall control such
Proceedings  and shall  consult in good faith with the Company as to the conduct
of such  Proceedings.  The Company shall reimburse Buyer for such portion of the
costs,  including legal costs, of conducting such  Proceedings as is represented
by the  portion of the Tax with  respect to such  Straddle  Period for which the
Company is liable pursuant to this  Agreement.  Each Party shall, at the request
and expense of the other, execute or cause to be executed any powers of attorney
or other documents reasonably requested by such requesting Party to enable it to
take any and all actions the requesting Party  reasonably  requires with respect
to any

                                      -43-

<PAGE>


Proceedings  which the  requesting  Party  controls.  The  failure by a Party to
provide  timely  notice under this Section  4.8(h) shall relieve the other Party
from its  obligations  under this Section 4.8 with respect to the subject matter
of any notification not timely forwarded, but only to the extent the other Party
has  suffered a loss or other  economic  detriment  because  of such  failure to
provide notification in a timely fashion.

                  (i) Transfer Taxes.  Notwithstanding  anything to the contrary
in this Agreement, including this Section 4.8, all transfer, documentary, sales,
use, stamp,  registration,  and other such Taxes incurred in connection with the
transactions  contemplated  by this  Agreement  shall be paid by Buyer when due,
with 50% of such payment to be deducted from the Estimated Consideration.  Buyer
and the Company shall cooperate in the filing of all necessary Returns and other
documentation with respect to all such transfer, documentary, sales, use, stamp,
registration and other Taxes.

         SECTION  4.9 Change of Name;  Use of  Company's  Name and  Initials  As
promptly as practicable after the Closing,  Buyer shall take any and all actions
necessary  to (i)  remove  the  Company's  name  from the  name in which  the TG
Business is conducted,  (ii) remove or cause to be removed all references to the
Company at the sites where the TG Business is  conducted,  and,  (iii) except to
the extent expressly permitted by the next sentence,  cease using that name, the
initials  "WJ" and any similar name or initials in its  operations or otherwise.
Effective as of the Closing,  the Company hereby grants Buyer and its affiliates
a royalty-free  world wide  perpetual  license to use the Company's name and the
initials  "WJ" in the  names  of  products  and  related  services  and  manuals
currently being  commercialized in the TG Business.  Buyer acknowledges that the
sole ownership such name and initials remains with Company. Buyer agrees that it
shall do nothing  inconsistent with such ownership.  Buyer shall comply with all
reasonable  requests of the Company or any  successor  in interest (by merger or
otherwise)  to the  Company  in  connection  with  Buyer's  use of such name and
initials.  Buyer's use of such name and initials shall  reasonably  conform with
the standards practiced by the Company in the past.

         SECTION 4.10 Further Action;  Reasonable  Commercial Efforts.  Upon the
terms and subject to the conditions of this Agreement,  each Party shall use its
reasonable  commercial  efforts to take, or cause to be taken,  all  appropriate
action, and to do or cause to be done, all things necessary, proper or advisable
under  applicable  laws and  regulations  to consummate  and make  effective the
transactions  contemplated by this  Agreement,  including but not limited to (i)
cooperating  in the  preparation  and  filing  of the Proxy  Statement,  and any
amendments  thereto,  (ii) using its reasonable  commercial  efforts to make all
required  regulatory  filings  and  applications  and to  obtain  all  licenses,
permits,  consents,  approvals,  authorizations,  qualifications  and  orders of
Governmental  Entities and third  parties to contracts  with the Company and its
subsidiaries  as  are  necessary  for  the   consummation  of  the  transactions
contemplated by this Agreement and to fulfill the

                                      -44-

<PAGE>


conditions to the Sale Transaction; and (iii) cooperating to effect the novation
of each Government  Contract and Bid which (as set forth in Schedule  3.1(f)) is
required to be novated in accordance  with all  applicable  governmental  rules,
regulations  and  requests,  provided,  however,  that the Company  shall not be
released  from any  obligations  to the  Buyer  expressly  provided  for in this
Agreement solely by reason of such novation and further provided that, following
the Closing,  the Company's obligation with respect to the process of continuing
to seek  such  novations  shall be to assist  Buyer,  which  shall be  primarily
responsible  for pursuing such  novations,  to the extent that Buyer  reasonable
requests such assistance.  To the extent  practicable in the  circumstances  and
subject  to  applicable  laws,  each  Party  shall  provide  the other  with the
opportunity  to review any  information  relating to such  Party,  or any of its
subsidiaries,  which  appears in any  filing  made  with,  or written  materials
submitted  to,  any  Governmental  Entity  or  any  non-governmental  person  in
connection with obtaining the Requisite Governmental Approvals and the Requisite
Non-Governmental  Approvals (as such latter term is defined in Section  5.1(h)).
In case at any time  after  the  Closing  any  further  action is  necessary  or
desirable to carry out the purposes of this  Agreement,  the proper officers and
directors of each Party shall use their  reasonable  commercial  efforts to take
all such necessary action.

         SECTION 4.11  Notification of Certain  Matters.  The Company shall give
prompt notice to Buyer,  and Buyer shall give prompt  notice to the Company,  of
(i)  the  occurrence  or   non-occurrence   of  any  event,  the  occurrence  or
non-occurrence of which would be likely to cause any  representation or warranty
contained in this Agreement to be untrue or inaccurate in any material  respect,
and (ii) any failure of the Company or Buyer, as the case may be, to comply with
or satisfy in any  material  respect any  covenant or  agreement  to be complied
with, or condition to be satisfied, by it hereunder; provided, however, that the
delivery  of any  notice  pursuant  to this  Section  4.11  shall  not  limit or
otherwise  affect the remedies  available  hereunder to the Party receiving such
notice.

         SECTION 4.12 Public  Announcements.  Each Party shall  consult with the
other before issuing any press release or otherwise making any public statements
with  respect to this  Agreement  and shall not issue any such press  release or
make any such  public  statement  prior to such  consultation,  except as may be
required  by law or any  listing  agreement  with  its  securities  exchange  or
quotation system.

         SECTION 4.13 Employee Transition.

                  (a) Prior to the Closing, the Company shall use its reasonable
commercial  efforts to assist Buyer in hiring the services of those TG Employees
and consultants of the TG Business identified by Buyer; provided,  however, that
the Company shall not be required to offer any TG Employees  additional monetary
or other  inducements  to achieve  that end beyond  those in place on the day of
this Agreement,  all of which shall be borne by the Company.  Buyer has informed
the Company that it intends to give appropriate

                                      -45-

<PAGE>


consideration  to the employment of the TG Employees by Buyer but nothing herein
shall be construed as requiring Buyer to continue the employment of any specific
TG Employee or to maintain any particular TG Plan.

                  (b) Prior to the Closing, the Company shall deliver to Buyer a
schedule  setting  forth,  with  respect  to all TG  Employees  (to  the  extent
permitted by applicable  law),  their  respective  employment  arrangements  and
entitlements,  including their respective annual salaries or hourly rates, start
dates,  positions,  benefits and  severance or  reduction-in-force  entitlements
under the TG Plans.

                  (c) Subject to any contrary  provision in Schedule  1.3, as to
those  persons who are TG  Employees  immediately  before the Closing or were TG
Employees at any previous time, all payments and other benefits due to them (and
their  beneficiaries  and  dependents)  in  respect of their  employment  by the
Company  before  the  Closing,  as  well as for any  severance,  termination  or
reduction-in-force  payment payable  directly as a result of the consummation of
the Sale  Transaction,  shall be for the  account of the Company and the Company
shall  indemnify Buyer and hold Buyer harmless  against,  from and in respect of
the costs of such  payments  and  benefits  and  shall  retain  sponsorship  and
liability with respect to all TG Plans.

         SECTION 4.14 Covenant Not To Compete.

                  (a) For a period  of three (3) years  from the  Closing  Date,
neither the Company nor any of its  affiliates  that is a  corporation  or other
juridical  entity shall  directly or  indirectly:  (i)  directly,  or indirectly
through any employee or affiliate,  manage or control any entity in, or conduct,
a business that would,  determined as of the Closing Date, be  competitive  with
the TG Business in any territory worldwide (a "Competitive Business"), provided,
however,  that the foregoing  prohibition  of this clause (i) shall not apply to
any other person which,  having acquired  control of the Company,  (1) continues
(either directly or through any affiliate) in any Competitive  Business in which
it was (directly or through any subsidiary)  engaged prior to such  acquisition,
or (2) develops any Competitive  Business  independently so long as, in any such
case,  such  person  does  not use  the  assets  or  properties  (including  the
Intellectual  Property) of the TG Business or any TG Employee to  participate in
or assist  (directly or  indirectly)  the conduct or  development of Competitive
Business,  or (3) in the case of any present or future affiliate of the Company,
such  affiliate  exercises  the rights held by it on the date of this  Agreement
under any License Agreement included in Schedule 3.1(v); (ii) solicit any of the
TG Employees for purposes of obtaining their  services,  or hire any TG Employee
unless  such TG  Employee  is not on the  date of  hire,  and has not been for a
period  of three  months  prior to the date of hire,  a TG  Employee,  provided,
however,  that, the foregoing prohibition of this clause (ii) shall not prohibit
the Company from placing advertisements in general circulation  publications for
employment  opportunities,  which  shall  not be

                                      -46-

<PAGE>


deemed a direct or indirect  solicitation of the TG Employees;  or (iii) solicit
any  customer  of the TG  Business  to  become  a  customer  of any  Competitive
Business.  If the final judgment of a court of competent  jurisdiction  declares
that any term or provision of this Section 4.14 is invalid or unenforceable, the
parties hereto agree that,  without  limiting the generality of Section 7.3, the
court making the determination of invalidity or unenforceability  shall have the
power to reduce the scope, duration or area of the term or provision,  to delete
specific words or phrases,  or to replace any invalid or  unenforceable  term or
provision with a term or provision that is valid and  enforceable and that comes
closest to  expressing  the  intention of the invalid or  unenforceable  term or
provision, and this Section 4.14 shall be enforceable as so modified.

                  (b) The Company  acknowledges  that Buyer would be irreparably
harmed by any breach of Section  4.14(a)  and that  there  would be no  adequate
remedy at law or in damages to  compensate  Buyer for such  breach.  The Company
agrees  that,  in the  event of any such  breach,  Buyer  shall be  entitled  to
injunctive relief requiring specific  performance by the Company of the breached
provisions of Section 4.14(a) and the Company consents to the entry thereof.

         SECTION 4.15. U.S. WARN Act. The Company agrees to provide any required
notice under the Worker Adjustment and Retraining  Notification Act ("WARN") and
any other  applicable  law and to  otherwise  comply with any such  statute with
respect to any "plant  closing" or "mass layoff" (as defined in WARN) or similar
event affecting  employees and occurring on or after the Closing or arising as a
result of the transactions contemplated hereby.

         SECTION 6.1  Termination.  This  Agreement may be  terminated,  and the
transactions  contemplated  hereby  may be  abandoned,  at any time prior to the
Closing,  either before or after  approval  thereof by the  shareholders  of the
Company:

                  (a) by mutual written consent of Buyer and the Company;

                  (b) by Buyer, upon any breach of any representation, warranty,
covenant or  agreement  of the Company  set forth in this  Agreement  where such
breach: (i) would prevent, either individually or in the aggregate with all such
other breaches, the

                                      -50-

<PAGE>


satisfaction  of the condition set forth in Section 5.2(a) or (b) and either (1)
cannot be cured prior to the  Terminal  Date,  or (2) has not been cured  within
thirty  (30)  days  after  the  date on which  written  notice  of such  breach,
specifying in reasonable detail the nature of such breach, was given by Buyer to
the Company; or (ii) was a violation of Section 4.6;

                  (c) by the  Company,  upon any  breach of any  representation,
warranty  or  agreement  of Buyer  set  forth  in this  Agreement  that,  either
individually  or in  the  aggregate,  would  prevent  the  satisfaction  of  the
condition  set forth in Section  5.3(a) or (b), if either (i) such breach cannot
be cured prior to the Terminal  Date,  or (ii) has not been cured within  thirty
(30) days after the date on which written  notice of such breach is given by the
Company to Buyer specifying in reasonable detail the nature of such breach;

                  (d)  by  either  Buyer  or  the  Company,   if  any  permanent
injunction or action by any Governmental  Entity  preventing the consummation of
the Sale  Transaction  shall  have  become  final  and  nonappealable;  provided
however,  that such right of termination  shall not be available to either Party
if such Party shall have failed to make reasonable efforts to prevent or contest
the  imposition  of such  injunction  or  action  and  such  failure  materially
contributed to such imposition;

                  (e) by either Buyer or the Company,  if (other than due to the
willful  failure of the Party seeking to terminate this Agreement to perform its
obligations  hereunder  which are  required to be  performed  at or prior to the
Closing)  the Closing  shall not have  occurred on or prior to January 14, 2000,
unless extended in writing by Buyer and Company (such date, or any date to which
it is so extended, being referred to as the "Terminal Date");

                  (f) by  either  Buyer or the  Company,  if (i) the vote of the
shareholders  of the Company on a motion to adopt and approve this Agreement and
the  Sale  Transaction  has  been  taken  at  the  Shareholders  Meeting  or any
postponement or adjournment  thereof and (ii) the vote in favor of such adoption
and approval was not  sufficient,  under the California Code and the Articles of
Incorporation of the Company, to cause such motion to pass; or

                  (g) by Buyer, if (i) the Board shall have withdrawn,  modified
or  changed  its  approval  or  recommendation  of this  Agreement  or the  Sale
Transaction  in any manner  which is adverse to Buyer,  or shall have  adopted a
resolution to do the foregoing, or (ii) a tender offer or exchange offer for 25%
or more of the  outstanding  shares of the  Company  Common  Stock is  commenced
(other than by Buyer or any of its  subsidiaries  or  affiliates),  the terms of
which offer do not expressly contemplate and permit the consummation of the Sale
Transaction,  and the Board  recommends  that the  shareholders  of the  Company
tender  their shares in such offer or  otherwise  fails to  recommend  that

                                      -51-

<PAGE>


such  shareholders  reject  such  offer  within  ten (10)  business  days of the
commencement thereof.

         SECTION 6.2 Fees and Expenses.

                  (a) Subject to Section  6.2(c),  the Company shall pay Buyer a
termination fee of $2,000,000  (the  "Termination  Fee") either:  (i) within one
business day following the  termination  of this  Agreement by Buyer pursuant to
Section 6.1(g);  or (ii) upon the execution of any definitive  agreement between
the  Company  and any  third  party  providing  for the sale of the TG  Business
(directly or through an  acquisition  of the Company as an  entirety)  where (1)
such  definitive  agreement is executed within 275 days from (and including) the
date on which this Agreement was terminated by either Buyer or the Company under
Section 6.1(f),  (2) at the time at which the vote was taken at the Shareholders
Meeting on the motion  referred to in Section 6.1(f) there was pending,  and had
not been  withdrawn,  a  publicly  announced  offer of the kind  referred  to in
Section  4.6(c),  and (3) the Board had not  withdrawn,  modified or changed its
approval or recommendation of this Agreement and the Sale Transaction,  so as to
entitle Buyer to terminate this Agreement under Section 6.1(g), by the time such
vote was taken.

                  (b) Except as set forth in  Sections  6.2(a) and  6.2(c),  all
costs and expenses  incurred in connection  with this Agreement shall be paid by
the Party incurring such costs and expenses, whether or not the Sale Transaction
is consummated.

                  (c) The Company  acknowledges  that a violation of Section 4.6
may inflict on Buyer  damages which are  substantial  but difficult to quantify.
Accordingly,  the Company agrees that if Buyer  terminates  this Agreement under
Section  6.1(b)(ii),  Buyer shall be entitled to recover,  as liquidated damages
and in lieu of any and all other  damages  or other  relief  for the  applicable
violation  of  Section  4.6,  the sum of  $4,000,000  plus the  fees,  costs and
expenses  reasonably  incurred  by Buyer  in  connection  with the  negotiation,
execution and performance of this Agreement;  provided,  however, that under any
circumstances  in which the Termination Fee and the liquidated  damages provided
for in this Section  6.2(c) would  otherwise both be payable as a result of such
termination, the liquidated damages provided for in this Section 6.2(c) shall be
Buyer's  sole  entitlement  and  remedy,  and the  Termination  Fee shall not be
payable.

         SECTION 6.3 Effect of  Termination.  In the event of the termination of
this Agreement  pursuant to Section 6.1, this Agreement shall  forthwith  become
void and there shall be no liability on the part of either Party except that the
provisions of Section  4.5(b),  Section 6.2 and all of Article VII shall survive
such  termination  indefinitely  (or to such earlier date as may be specified by
the terms of such  provision);  provided,  however,  that  nothing  herein shall
relieve any Party from liability for any willful and material breach hereof; and
provided further, that any action that the Board takes in compliance with

                                      -52-

<PAGE>


Sections  4.2(c) or 4.6(c) shall not constitute a willful and material breach of
this Agreement by the Company.

         SECTION 6.4 Amendment.  This Agreement may be amended by the Parties by
action  taken by the Board and the Board of Directors of Buyer at any time prior
to the Closing; provided, however, that, after approval of this Agreement by the
shareholders  of the Company,  no  amendment  may be made which would reduce the
amount or change the type of  consideration  to be received.  This Agreement may
not be amended except by an instrument in writing signed by the Parties.

         SECTION 6.5 Waiver. At any time prior to the Closing,  either Party may
(a) extend the time for the  performance of any of the obligations or other acts
of the other  Party,  (b)  waive any  inaccuracies  in the  representations  and
warranties contained herein or in any document delivered pursuant hereto and (c)
waive compliance with any of the agreements or conditions  contained herein. Any
such extension or waiver shall be valid if set forth in an instrument in writing
signed by the Party or Parties to be bound thereby.

relations  between the Parties  shall be governed by and construed in accordance

rules  thereof.  Except as otherwise  provided in this  Agreement,  any claim or
dispute  arising out of or relating to this  Agreement,  or the  interpretation,
making, performance,  breach or termination thereof, shall be finally settled by
binding  arbitration  in San  Francisco,  California,  under  the  rules  of the
American  Arbitration  Association ("AAA") then in effect by a single arbitrator
mutually  agreeable  to the Company and Buyer.  In the event that within  thirty
(30) days after submission of any dispute to arbitration,  the Company and Buyer
do not mutually agree on a single arbitrator,  the Company, on the one hand, and
Buyer,  on the other hand,  shall each select one  arbitrator  and the AAA shall
select a third arbitrator.  The arbitrator(s)  shall have the authority to grant
any  equitable  and legal  remedies  that  would be  available  in any  judicial
proceeding  instituted to resolve a dispute.  Judgment on the award  rendered by
the arbitrators  may be entered in any court having  jurisdiction  thereof.  The
arbitrator(s)  may award to the prevailing  Party,  if any, as determined by the
arbitrator(s)  all of its costs and fees,  including  AAA  administrative  fees,
arbitrator fees, attorneys' fees, expert fees, witness fees, travel expenses and
out  of  pocket  expenses  (including  such  expenses  as  copying,   telephone,
facsimile,  postage  and  courier  fees).  The Parties may apply to any court of
competent jurisdiction for a temporary restraining order, preliminary injunction
or other  interim or  conservatory  relief as necessary  without  breach of this
arbitration provision without any abridgment of the powers of the arbitrator(s).
The Parties agree that, the provisions of applicable law  notwithstanding,  they
will not request and the arbitrator(s) shall have no authority to award punitive
or exemplary damages against any party.

valuable consideration, the receipt of which is hereby acknowledged, the parties
agree as follows:

                                      A-1

<PAGE>


         1.  Appointment.  Buyer and the Company hereby appoint the Escrow Agent
as escrow  agent to serve in such  capacity,  in  accordance  with the terms and
conditions set forth in this Escrow  Agreement.  The Escrow Agent hereby accepts

         2. Purchase Agreement.  The Escrow Agent acknowledges receipt of a copy
of the Purchase Agreement; provided, however, that, except for reference thereto
for definitions of certain words or terms not defined  herein,  the Escrow Agent
is not charged with any duties or responsibilities  with respect to the Purchase

         3.  Escrow  Amount;  Escrow  Fund.  On the  Closing  Date,  Buyer shall
deposit,  or shall cause to be deposited,  the Escrow  Amount  directly with the

the Escrow Fund, hereunder.

         4. Investment.

                  (a) The Escrow  Fund shall be  invested  by the Escrow  Agent,
without  distinction  as to  principal  and  income,  upon  receipt  of  written
instructions  in the form  attached  hereto as Exhibit A executed  by one of the
officers  of Buyer  named in Exhibit B hereto and by one of the  officers of the
Company named in Exhibit C hereto, in one or more of the following  investments:
(i) interest  bearing open ended or time deposits of any United States bank with
assets in excess of U.S.  $500,000,000  (including any affiliate of Escrow Agent
that meets such  capital  requirements);  or (ii) any other  investment  vehicle
pursuant  to the  written  instructions  from Buyer and the  Company  including,
without  limitation,  money market and other mutual funds  offered or advised by
Escrow Agent or any of Escrow Agent's affiliates.  The Escrow Agent shall not be
liable for any loss  resulting  from any  investment  made  pursuant  to written
instructions of Buyer and the Company. Notwithstanding the foregoing, the Escrow
Agent  shall  have the  power to sell or  liquidate  the  foregoing  investments
whenever the Escrow Agent shall be required to release all or any portion of the
Escrow Fund  pursuant to Section 5. In effecting  any such sale or  liquidation,
the Escrow Agent may, without inquiry,  rely upon written  instructions from one
of the  officers  of Buyer  named in  Exhibit B and one of the  officers  of the
Company named in Exhibit C, or a successor of any such authorized officer, as to
which investments to sell or liquidate.

                  (b) The  parties  to this  Escrow  Agreement  (the  "Parties")
acknowledge  that payment of any interest  earned on the this Escrow Amount will
be subject to backup  withholding  penalties unless either a properly  completed
Internal  Revenue Service Form W8 or W9 certification is submitted to the Escrow
Agent at the time of execution of this Escrow Agreement.

         5. Claims Upon Escrow Fund.

                                      A-2

<PAGE>


                  (a) In the event that any Buyer  Indemnified Party has a Claim
against  the  Company  for which  such  Buyer  Indemnified  Party  desires to be
indemnified as provided in the Purchase  Agreement,  the Indemnified Party shall
notify the Company of such Claim in accordance  with Section 4.7 of the Purchase
Agreement,  with a copy to the Escrow Agent, specifying the nature of such Claim
and the amount or the estimated  amount thereof to the extent then feasible (the
"Claim Notice"). If the Company does not notify in writing the Buyer Indemnified
Party  within  thirty (30) days after the date of  delivery of the Claim  Notice
that the Company disputes such Claim,  with a statement in reasonable detail (to
enable the  Indemnified  Party to  understand  the nature of the dispute) of the
basis of such position (a "Notice of  Objection"),  a copy of which is delivered
to the  Escrow  Agent,  the amount of such Claim  shall be  conclusively  deemed
indemnifiable  from the Escrow Fund,  and the Escrow Agent shall  deliver to the
Buyer  Indemnified  Party out of the Escrow Fund cash in an amount  equal to the
Damages as specified in the Claim Notice.

                  (b)  In  case  a  Notice  of  Objection  is  delivered  to the
Indemnified Party in accordance with this Section 5, the Indemnified Party shall
respond in a written  statement  to the Notice of Objection  within  thirty (30)
days and,  for sixty (60) days  thereafter,  the parties  shall  attempt in good
faith to resolve such dispute.  If the parties  should so agree, a memorandum (a
"Certificate of Resolution")  setting forth such agreement shall be prepared and
signed by both  parties,  and the Escrow  Agent shall be entitled to rely on the
Certificate of Resolution and distribute cash from the Escrow Fund in accordance
with the terms thereof.

                  (c) If the  parties do not  resolve  the  dispute  within such
sixty (60) day period,  either party may demand arbitration of the matter unless
the amount of the Damages is at issue in pending  litigation  with a third party
or is based on an asserted  claim by a third party,  in which event  arbitration
shall not be commenced until such amount is ascertained or both parties agree to
arbitration.  Any  arbitration  under  this  Section  5 shall  be  conducted  in
accordance  with Section 7.6 of the Purchase  Agreement  and the decision of the
arbitrator(s)  shall be written and shall be  supported  by written  findings of
fact and conclusions which shall set forth the award, judgment,  decree or order
(an "Award")  determined by the arbitrators.  The Escrow Agent shall be entitled
to act in  accordance  with an Award and make or  withhold  payments  out of the
Escrow Fund in accordance herewith.

         6. Escrow Provisions.

                  (a)  The   Escrow   Agent  may  rely,   without   inquiry   or
investigation,  and shall be protected in acting or refraining from acting, upon
any written notice, request, waiver, consent, receipt or other paper or document
from any officer of the Company named in Exhibit C or any officer of Buyer named
in Exhibit B, not only as to its due

                                      A-3

<PAGE>


execution and the validity and  effectiveness of its provisions,  but also as to
the truth of any information  therein  contained,  that the Escrow Agent in good
faith believes to be genuine. The Escrow Agent may disregard any and all notices
or  instructions  received  from any  source,  except  only (i) such  notices or
instructions as are  specifically  provided for in this Escrow  Agreement or any
other  notice  signed by the Company and Buyer and (ii) orders or process of any
court entered or issued with or without  jurisdiction.  If from time to time any
property held  pursuant to this Escrow  Agreement  becomes  subject to any levy,
attachment,   order,   judgment,   decree,   injunction   or   other   judicial,
administrative,  or regulatory  process  ("Order"),  the Escrow Agent may comply
with any such Order without liability to any person,  even though such Order may
thereafter be annulled, reversed, modified or vacated.

                  (b) The  Escrow  Agent  shall not be  liable  for any error of
judgment,  or for any act done or step taken or omitted by it in good faith,  or
for any mistake of fact or law, or for anything  which it may do or refrain from
doing in  connection  herewith,  except for any  liability  arising from its own
gross negligence,  willful misconduct or bad faith. In no event shall the Escrow
Agent be liable to any person, for punitive,  special, indirect or consequential
damages of any kind, even if it is advised of the possibility thereof.

                  (c) The Escrow Agent shall be entitled to consult with outside
counsel,  of its choice with  respect to the  interpretation  of the  provisions
hereof and any other legal matters relating hereto, and shall be fully protected
in taking any action or omitting to take any action in good faith in  accordance
with the written  advice of such  outside  counsel  provided  the other  parties
hereto have been given prior notice of the Escrow  Agent's  selection of outside
counsel and a copy of such written advice.

                  (d) Each of Buyer and the Company agrees to indemnify and hold
the Escrow Agent harmless for one-half (1/2) of any and all claims, liabilities,
costs,  payments  and  expenses  of the  Escrow  Agent  in  connection  with its
performance of its duties hereunder,  including without  limitation,  reasonable
fees and expenses of counsel for court actions,  or for anything done or omitted
by it in the  performance  of this Escrow  Agreement,  except as a result of the
Escrow Agent's own gross negligence, willful misconduct or bad faith.

                  (e) All  evidence  of  investment  of funds in the Escrow Fund
(including, but not limited to, savings account passbooks,  certificates,  notes
and other similar items) shall be kept in a place of safekeeping at an office of
the  Escrow  Agent,  or with a safe  deposit  company,  including  any such safe
deposit  company  owned  in  whole  or in part  by the  Escrow  Agent  or by any
affiliate of the Escrow Agent. The Escrow Agent shall keep accurate  accounts of
all income and interest  earned by the funds in the Escrow Fund.  Within  thirty
(30) days after the close of each calendar month, the Escrow Agent shall

                                      A-4

<PAGE>


provide the Company and Buyer  statements on deposits and other  investments  of
the Escrow Fund in accord with its usual practices.

                  (f) One half  (1/2) of the fees and  related  expenses  of the
Escrow  Agent for its  services  hereunder  (including  fees and expenses of its
outside  counsel)  shall be paid by Buyer  and one half  (1/2) of such  fees and
expenses  shall be paid by the Company.  The Escrow  Agent's fees for its duties
shall be $__________ per year plus reasonable  out-of-pocket costs. Such amounts
shall be in addition to other amounts payable by the parties pursuant to Section
6(d) and other provisions hereof.

                  (g) None of the provisions  contained in this Escrow Agreement
shall  require  the  Escrow  Agent  to  advance  or risk  its own  funds  in the
performance of its duties herein described.

                  (h) Without limiting the Escrow Agent's rights under any other
provision  hereof,  whenever the Escrow Agent should  receive or become aware of
any conflicting  demands or claims with respect to this Escrow  Agreement or the
rights of any of the parties hereto or any property held  hereunder,  the Escrow
Agent may without  liability refrain from any action until the conflict has been
resolved, or alternatively, may tender into the registry or custody of any court
which the Escrow Agent determines to have  jurisdiction all money or property in
its hands under this Escrow Agreement,  together with such legal pleadings as it
deems appropriate,  less a reasonable allowance for its legal fees and expenses,
and thereupon be discharged from all further duties and  liabilities  under this
Escrow Agreement. Any inaction or filing of proceedings pursuant to this section
shall not deprive the Escrow Agent of its  compensation  during such inaction or
prior filing.

                  (i) Except as and if specifically  provided herein  concerning
investments of cash, the Escrow Agent shall have no liability to pay interest on
any money held pursuant to this Escrow  Agreement.  The Escrow Agent may use its
own bond  department  or any  affiliate of Escrow Agent in purchasing or selling
securities.  The Escrow Agent shall not be liable for any depreciation or change
in the value of such documents or securities or any property  evidenced  thereby
or for any losses  incurred  in  liquidating  securities  or other  property  to
satisfy a distribution  request. All distributions  provided for hereunder shall
be made by the Escrow Agent from the Escrow Fund to the extent thereof,  subject
to deductions allowed to be made by Escrow Agent as provided elsewhere herein.

                  (j) The Escrow Agent shall not be responsible for any recitals
of fact in this  Escrow  Agreement,  or for the  sufficiency,  form,  execution,
validity or  genuineness  of any  documents or securities  deposited  under this
Escrow  Agreement  or for any  signature,  endorsement  or  lack of  endorsement
thereon, or for the accuracy of any description

                                      A-5

<PAGE>


therein,  or for the identity,  authority or rights to the persons  executing or
delivering the same or this Escrow Agreement.

                  (k)   Although   the   Escrow   Agent  may   demand   specific
authorizations (including corporate resolutions, incumbency certificates and the
like) or identification from another Party or its representative prior to taking
any action  hereunder,  no such demand shall  constitute a waiver or deprive the
Escrow Agent of the protections afforded by this Escrow Agreement.

                  (l) The Escrow Agent shall not be  responsible  for any delays
or failure to perform  caused by  circumstances  reasonably  beyond its control,
including  but not limited to:  breaches by other  parties of their  obligations
hereunder, delays by messengers or other independent contractors;  mechanical or
computer failures;  malfunctioning or breakdowns in public utilities, securities
exchanges;  Federal  Reserve Banks or securities  depositories;  interference by
governmental  units;  strikes,  lockouts or civil  disobedience;  fires or other
casualties; acts of God or other similar occurrences.

         7. Successor  Escrow Agent.  The Escrow Agent,  or any  successor,  may
resign at any time upon giving  written notice to Buyer and the Company at least
thirty (30) days before such resignation shall take effect.  In addition,  Buyer
and the Company may terminate  the Escrow  Agent's  appointment  as escrow agent
upon giving  written  notice  (jointly  signed by Buyer and the  Company) to the
Escrow  Agent at least  thirty  (30) days  before  such  termination  shall take
effect.  If the Escrow Agent shall resign,  be terminated or be unable to serve,
then it shall be succeeded by such bank or trust company  jointly named by Buyer
and the Company in such thirty (30) day  period,  or if no such  appointment  is
made  by that  time  then it  shall  be  succeeded  by a bank or  trust  company
appointed  by a court of  competent  jurisdiction  upon  petition  by any of the
Escrow  Agent,  Buyer or the Company (in which action the other parties shall be
afforded a reasonable  opportunity to participate) to appoint a successor escrow
agent,  or the Escrow  Agent may tender the Escrow  Fund into court as  provided
elsewhere in this Escrow  Agreement.  The Escrow Agent shall transfer the Escrow
Fund to its successor and shall  thereupon be discharged  from any obligation to
perform further  services under this Escrow  Agreement,  and the successor shall
thereupon  succeed to all of the rights,  powers and duties and shall assume all
of the  obligations  of  the  Escrow  Agent  originally  named  in  this  Escrow
Agreement.   Notwithstanding   any  other  provision   hereof,   the  respective
obligations  of Buyer and the Company to the Escrow Agent under Section 6(d) and
6(f) shall survive any resignation or removal of Escrow Agent or any termination
of this Escrow Agreement.

         8. Payment of Taxes.  The Company  shall be treated as the owner of the
Escrow Fund for all Tax purposes while and to the extent that the Escrow Fund is
held by

                                      A-6

<PAGE>


the Escrow Agent.  The Escrow Agent shall furnish such  information to the other
Parties as shall be  requested in writing for tax  preparation  purposes by such
Parties.

         9. Release Dates; Termination.

                  (a)  Subject to  paragraph  (b) of this  Section 9, the Escrow
Agent shall release from escrow  hereunder,  and distribute to the Company,  the
Escrow Fund on the 90th day from (and  including) the Closing Date (the "Initial
Release Date").

                  (b)  Notwithstanding  any  provision of paragraph  (a) of this
Section 9, if, on the Initial Release Date, the amount (the "Retention  Amount")
that is the sum of (i) the maximum aggregate amount  (determined on the basis of
the  applicable  Claims  Notices) that would be necessary to satisfy all Pending
Claims of Buyer  existing  on the Initial  Release  Date which have not been the
subject of a Certificate  of Resolution or an Award,  (ii) the aggregate  amount
that is then payable to Buyer under any  Certificate  of Resolution  but has not
yet been paid,  and (iii) the  aggregate  amount  that is then  payable to Buyer
under any Award but has not yet been paid,  is greater than zero,  the Retention
Amount  shall be withheld  from  release and the amount that would  otherwise be
released  shall be reduced (to zero if  necessary),  dollar for  dollar,  by the
Retention Amount.

                  (c) If, in  accordance  with  paragraph (b) of this Section 9,
less than all of the Escrow Fund is released and  distributed  to the Company on
the Initial  Release  Date,  the Retention  Amount shall  continue to be held in
escrow in  accordance  with this Escrow  Agreement  until all Pending  Claims of
Buyer existing on the Initial Release Date have been  definitively  resolved and
payment has been made of the aggregate of (i) all amounts payable to Buyer under
all  Certificates  of  Resolution  issued  after the Initial  Release  Date with
respect to such Pending  Claims and (ii) all amounts  payable to Buyer under all
Awards  issued  after the  Initial  Release  Date with  respect to such  Pending
Claims,  whereupon  the balance  remaining  in the Escrow Fund shall be released
from the Escrow Fund as the final release  thereof and shall be  distributed  to
the Company (the "Final Release").

                  (d) Unless  extended  in writing  by the  Parties,  the escrow
provided for in this Escrow Agreement shall expire on the date (the "Termination
Date")  which is the later of (i) the Initial  Release  Date or (ii) the date of
the Final Release.

may, to the extent legally allowed,  waive compliance with any of the agreements
or conditions for the benefit of such party contained  herein.  Any agreement on
the part of a Party to any such  extension  or waiver shall be valid only if set
forth in an instrument in writing signed on behalf of such Party.

                  (d) The words "include,"  "includes" and "including" when used
in this  Escrow  Agreement  shall be deemed in each case to be  followed  by the
words "without  limitation." The headings contained in this Escrow Agreement are
for  reference  purposes  only and shall not  affect in any way the  meaning  or
interpretation of this Escrow Agreement.

                  (e)  This  Escrow  Agreement  may be  executed  in one or more
counterparts,  all of which shall be considered  one and the same  agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and  delivered  to the other  party,  it being  understood  that all
parties need not sign the same counterpart.

                  (f) This Escrow  Agreement,  the Purchase  Agreement (but only
for  purposes of the  definitions  set forth  therein  and any other  provisions
thereof expressly  referenced in this Escrow Agreement) and the exhibits hereto,
constitute  the entire  agreement  among the parties with respect to the subject
matter  hereof and  supersede  all prior  agreements  and  understandings,  both
written and oral, among the Parties with respect to the subject matter hereof.

                  (g) Neither this Escrow Agreement nor any beneficial  interest
therein may be sold, assigned or otherwise  transferred,  including by operation
of law, by Buyer or the Company or be taken or reached by any legal or equitable
process in  satisfaction of any debt or other liability of Buyer or the Company,

jurisdiction to be illegal, void or unenforceable,  the remainder of this Escrow
Agreement  shall  continue in full force and effect and the  application of such
provision  to  other  persons  or  circumstances  shall  be  interpreted  so  as
reasonably to effect the intent of the parties hereto. The Parties further agree
to replace such void or unenforceable  provision of this Escrow Agreement with a
valid and enforceable  provision that will achieve, to the extent possible,  the
economic, business and other purposes of such void or unenforceable provision.

will not preclude the exercise of any other remedy by such Party.

                  (k) This Escrow  Agreement  shall be governed by and construed
in  accordance  with the laws of  California  regardless  of the laws that might
otherwise govern under applicable principles of conflicts of laws thereof.

                  (l) No provisions of this Escrow  Agreement are intended,  nor
shall be interpreted, to provide or create any third party beneficiary rights or
any other rights of any kind in any client, customer,  affiliate, partner of any
party hereto or any other Person unless specifically provided otherwise herein.

IV.      INFRINGEMENT

         4.1 Notice of Infringement

         If either Party  becomes aware of any action by a third party which may
infringe  any of the patents or  know-how  licensed  hereunder,  then such Party
shall promptly give written notice thereof to the other Party.

         4.2 Enforcement Against Infringers

         Upon  receipt of the  notification  in Section 4.1, the Party which has
title to the  patents or  know-how  at issue  shall have the right,  but not the
obligation,  to take action,  at

                                      B-4

<PAGE>


its own expense, to protect the rights of the Parties, including but not limited
to the filing of  lawsuits.  In the event the Party who has title to the patents
or  know-how at issue  decides  not to commence an action or pursue  claims with
respect to any acts of infringement,  then the other Party shall have the right,
but not the  obligation,  at its own expense,  to pursue the action in its name,
and the Party which has title shall take all steps necessary to provide standing
to the other Party.  The non-acting  Party shall  reasonably  cooperate with the
Party  bringing the action,  and shall bear its own expenses in connection  with
assisting  the Party  bringing the action.  All damages,  awards and  settlement
proceeds in such  actions  shall be retained by the Party  bringing  the action.
Notwithstanding  anything to the contrary,  in no event shall the Party bringing
the action be permitted,  as part of the settlement of any such action, to admit
the  invalidity  of any patent or know-how to which the other Party has title or
under which the other  Party has a license  without  the other  Party's  written
consent, which consent shall not be unreasonably withheld or delayed.

         4.3 Infringement Claims

         If the production,  sale or use of any products or services pursuant to
this Cross  License  Agreement  results in any claim or action by a third  party
alleging  patent  infringement  against either Party,  then the Party who is the
subject  of the claim or action  shall  have the  exclusive  right to defend and
control the defense of any such claim or action,  at its own expense;  provided,
however,  that the  other  Party  shall  have the right to  participate  in such
defense at its own expense if the  disposition of the claim or action may affect
the rights or  interest  of such other Party  granted  under this Cross  License
Agreement.  If both  Parties are the  subject of the claim or action,  then both
Parties shall share control of the defense and shall equally bear the expense of
the claim or action.  Notwithstanding  anything to the  contrary  herein,  in no
event shall the Party having sole or shared control of the defense be permitted,
as part of the  settlement of any such claim or action,  to admit the invalidity
of any patent or  know-how to which the other Party has title or under which the
other Party has a license,  without that other Party's  written  consent,  which
consent shall not be unreasonably withheld or delayed.

V.       CONFIDENTIALITY

         5.1 The Parties  acknowledge  that  certain of the  Company  Associated
Know-How and TG  Associated  Know-How  licensed  hereunder  may be  Confidential
Information.  Each  Party  shall  treat as  confidential  all such  Confidential
Information and all other Confidential  Information of the other Party and shall
not use any such Confidential  Information  except as permitted under this Cross
License Agreement.  Neither Party shall disclose the Confidential Information of
the other Party to any third party except as may be allowed in  connection  with
the rights of the other  Party,  and in such case the third party shall be bound
by similar confidentiality terms. Each Party shall

                                      B-5

<PAGE>


use at least  the same  procedures  and  degree  of care for the  other  Party's
Confidential  Information  which it uses to prevent  the  disclosure  of its own
confidential information of like importance, but in no event less than due care.

         5.2  Notwithstanding  Section  5.1  above,  neither  Party  shall  have
liability to the other Party with regard to any Confidential  Information of the
other Party which:

                  (a) was  generally  known in the public  domain at the time it
was disclosed,  or becomes generally known in the public domain through no fault
of the receiving Party;

                  (b) becomes known to the  receiving  Party from a source other
than the disclosing Party without breach of this Cross License  Agreement by the
receiving  Party,  and  otherwise  not in  violation of the  disclosing  Party's
rights;

                  (c) is independently  developed by the receiving Party without
access to the Confidential Information of the disclosing Party;

                  (d) is  disclosed  with  the  prior  written  approval  of the
disclosing Party;

                  (e) is  disclosed by the  disclosing  Party to any third party
without imposing similar restrictions of confidentiality; or

                  (f) is disclosed  pursuant to the  requirement or request of a
court on Governmental Entity, or by operation of law; provided,  however,  that,
if possible,  the  disclosing  Party is first given an  opportunity to object to
such disclosure.

         This  Article  V  shall  survive  termination  of  this  Cross  License
Agreement.

VI.      TERM

provision without any abridgment of the powers of the arbitrator(s). The Parties
