                                   THE CLOSING

     2.1  PLACE AND DATE.  The  closing of  the sale  and purchase of the Assets
(the "Closing"), and the assumption of the Assumed Liabilities, shall take place
at the offices of Cooley  Godward  LLP,  One  Maritime  Plaza,  20th Floor,  San
Francisco,  California, or such other place upon which the parties may agree, on
the first  business day following the date upon which each of the  conditions to
closing  set  forth  in  Articles  8 and 9 of  the  Agreement  shall  have  been
satisfied.  The day on which the  Closing  actually  occurs is herein  sometimes
referred to as the "Closing Date."

     2.2  PURCHASE PRICE.

          (a)    On the  terms and  subject  to the conditions set forth in this
Agreement,  Buyer  agrees to pay to Seller at the Closing an  aggregate  of U.S.
$61,500,000  and to assume the Assumed  Liabilities  as provided in Section 2.4.
The Purchase Price shall be paid by the wire transfer of  immediately  available
funds to such bank  account or  accounts as are  specified  by Seller in written
instructions given to Buyer at least three days prior to the Closing.

          (b)    Notwithstanding  anything  to  the  contrary contained in  this
Agreement,  the  purchase  price is subject to  adjustment  in  accordance  with
Section 2.2(c) or (d), as the case may be. Attached hereto as Schedule 2.2(b) is

respect to certain assets, and other procedures heretofore agreed upon by Seller
and Buyer

                                       3



<PAGE>



(the "Adjusted April Balance Sheet"). Promptly following the Closing, Seller and
Buyer shall  jointly  prepare a balance sheet as of the Closing Date in a manner
consistent  with the  preparation  of the  Adjusted  April  Balance  Sheet  (the
"Closing  Balance  Sheet").  If Buyer and Seller  disagree  with  respect to any
matter  relating  to  the  preparation  of  the  Closing  Balance  Sheet,   such
disagreement  shall  be  promptly  submitted  for  resolution  to  a  nationally
recognized  accounting  firm  that  is  acceptable  to  Seller  and  Buyer  (the
"Accounting  Firm"). The determination of the Accounting Firm shall be final and
binding upon Seller and Buyer and the fees and expenses of the  Accounting  Firm
shall be borne equally by Seller and Buyer.

          (c)    If the net assets  reflected on  the Closing  Balance Sheet are
less than the net assets  reflected on the Adjusted April Balance Sheet,  Seller
will  promptly  pay to Buyer the amount of such  shortfall  by wire  transfer of
immediately  available  funds to such bank  account or  accounts  as Buyer shall
specify in written instructions.

          (d)    If the net assets reflected on the Closing Balance Sheet exceed
the net  assets  reflected  on the  Adjusted  April  Balance  Sheet,  Buyer will
promptly  pay to Seller the amount of such  excess,  such  payment to be made by
wire transfer of immediately available funds to such bank account or accounts as
Seller shall specify in written instructions.

     2.3   ALLOCATION OF  PURCHASE  PRICE.  The parties  agree to  allocate  the
aggregate of the Purchase Price and the Assumed Liabilities  (collectively,  the
"Aggregate  Purchase Price") among the Assets in accordance with section 1060 of
the Code as mutually  agreed to by the  parties  within 180 days  following  the
Closing.  All such mutually agreed to allocations shall be used by each party in
preparing  any  filings  required  pursuant  to Section  1060 of the Code or any
similar  provisions of state or local law and all relevant  income and franchise
tax returns.  Neither Buyer nor Seller will take any position  before any taxing
authority or in any judicial  proceeding that is inconsistent with such mutually
agreed to allocations  without the prior consent of the other party. The parties
shall in good  faith  exercise  reasonable  efforts  to  support  such  reported
allocations in any audit proceedings initiated by any taxing authority.

     2.4   ASSUMPTION OF LIABILITIES.  Subject to the terms and  conditions  set

discharge of any former  employee of the Seller any time more than 60 days after
the Closing;  (b) all product  warranty  obligations  of Seller  relating to the
Business and identified on Schedule 2.4(b);  (c) all liabilities and obligations
of Seller to be paid or  performed  from and after  the  Closing  Date  under or

other like liabilities or obligations arising from or as a result of a breach of
any contract by Seller or Seller's  failure to satisfy any requirement  which it
was  required to satisfy on or prior to the  Closing;  (d) all  liabilities  and
obligations  of  Seller  relating  to or  arising  out of the  operation  of the
Business in the ordinary course and reflected on the Closing Balance Sheet,  (e)
all  liabilities  and  obligations of Seller  relating to or arising out of cost
overruns or  adjustments  to rates and factors used in pricing work performed or
services  provided to customers  prior to the Closing;  (f) all  liabilities and
obligations  of Seller  relating  to or arising out of the  lawsuits,  claims or
other

matters  described in Schedule 2.4(f);  and (g) fifty percent (50%) of all other
liabilities and obligations  (other than Excluded  Liabilities)  relating to the

liabilities, the "Other Liabilities").

     2.5    EXCLUDED  LIABILITIES.  Buyer  shall  not  assume  or in  any way be
responsible for, and Seller shall pay,  discharge and be solely responsible for,

Liens  relating to Taxes which are not yet subject to penalties for  non-payment
or which are being contested in good faith and by appropriate proceedings;

          (e)    any   environmental  liabilities   arising  out  of  conditions
existing or activities  occurring  with respect to the Assets or the Business on
or prior to the Closing and any other environmental  liabilities relating to any
other of Seller's activities or operations prior to the Closing;

          (f)    except  as   otherwise   provided   herein,  any  liability  or
obligation  to any  employee or former  employee of Seller for  compensation  or
benefits incurred or accrued or otherwise  arising out of services  performed on
or prior to the Closing Date, or if later,  the employees  date of hire by Buyer
under Section 6.4;

          (g)    any  deferred  compensation  obligation  or  any  liability  or
obligation of Seller arising out of or in connection  with any employee  benefit
plan;

rights and claims of others,  other than Permitted  Liens, to all of the

                                       5





<PAGE>



Assets,  and Buyer shall  deliver to Seller such  instruments  of  assumption as
shall be  satisfactory  in form and substance to Seller to ensure that Buyer has
assumed all of the Assumed Liabilities.

     2.7   CONSENT OF THIRD PARTIES. Notwithstanding anything to the contrary in
this  Agreement,  this Agreement  shall not constitute an agreement to assign or
transfer any Governmental Approval, instrument, contract, lease, permit or other
agreement or arrangement or any claim,  right or benefit  arising  thereunder or
resulting  therefrom if any assignment or transfer or an attempt to make such an
assignment or transfer  without the consent of a third party would  constitute a
breach or violation  thereof or affect  adversely  the rights of Buyer or Seller
thereunder;  and no transfer or  assignment  to Buyer by Seller of any  interest
under any such Governmental  Approval,  instrument,  contract,  lease, permit or
other agreement or arrangement  that requires the consent of a third party shall
be made  until such  consent  or  approval  is  obtained.  In the event any such
consent or approval is not  obtained  on or prior to the  Closing  Date,  Seller

perform  for the  account  of Buyer  any  rights  of  Seller  arising  from such
Governmental Approval, instrument, contract, lease, permit or other agreement or
arrangement,  provided that Buyer shall undertake to pay, perform,  discharge or
satisfy the corresponding  liabilities and obligations for the enjoyment of such
benefit to the extent Buyer would have been responsible therefor if such consent
or approval had been obtained.

     2.8   BOOKS AND  RECORDS.  From and after the  Closing  and until the sixth

and during normal  business  hours,  reasonable  access to any books and records
that pertain to the Business but which are not Books and Records,  and (b) Buyer
agrees to grant to Seller,  upon  reasonable  notice and during normal  business
hours,  reasonable  access to any Books and Records  included in the Assets that

time after the Closing Date,  upon  reasonable  request from the other party, to
do, execute, acknowledge and deliver, as appropriate,  such further acts, deeds,
assignments,  transfers, conveyances and powers of attorney as may reasonably be
required for the better assigning,  transferring,  granting, conveying, assuring
and confirming to such other party, or its successors and assigns, of any of the

                    REPRESENTATIONS AND WARRANTIES OF SELLER

     Except to the  extent set forth in the  Disclosure  Schedule  delivered  to
Seller  contemporaneously  herewith (the  "Disclosure  Schedule"),  of which the
Schedules referred to below are a part, and in the documents and other materials
identified in the Disclosure Schedule,  and subject to the limitations contained
in Article  11,  Seller  represents  and  warrants  to Buyer that the  following
statements are true in all material respects as of the date of this Agreement:

     3.1   ORGANIZATION,  STANDING,  ETC. OF  SELLER;  CORPORATE  AUTHORIZATION;
           ENFORCEABILITY.

          (a)    Seller is a corporation duly organized, validly existing and in
good  standing  under the laws of the State of  Delaware  and has all  requisite
corporate  power and  authority to carry on the Business as currently  conducted
and to own or lease and to operate the  properties  of the  Business.  Seller is
qualified  to do  business  and is in good  standing in each state of the United
States where the failure to so qualify would have a material  adverse  effect on
the Assets or the Business (taken as a whole) or financial  condition or results
of operations of the Business (a "Material Adverse Effect on the Business").

          (b)    The execution  and delivery of  this  Agreement  and all  other
documents and instruments  executed or to be executed by Seller pursuant to this
Agreement,  and the  consummation of the  transactions  contemplated  hereby and
thereby,  have been duly authorized by all necessary  corporate and other action
on the part of Seller.  This Agreement and all other  documents and  instruments
executed or to be executed by Seller  pursuant to this  Agreement  have been, or
will have been, at the time of their respective executions and deliveries,  duly
executed and delivered by a duly authorized officer of Seller.

          (c)    This  Agreement  constitutes  the  valid  and  legally  binding
obligation of Seller,  enforceable in accordance with its terms,  except as such
enforceability  may  be  limited  by  equitable  principles  and  by  applicable
bankruptcy, insolvency, reorganization,  arrangement, moratorium or similar laws
relating to or affecting the rights of creditors generally.

     3.2   CERTIFICATE OF INCORPORATION AND BYLAWS. Copies of the certificate of
incorporation   and  bylaws  or  other   organizational   documents   of  Seller
(collectively,  the  "Organizational  Documents")  have been made  available  to
Buyer, and each such copy is true, correct and complete.

     3.3   COMPLIANCE  WITH  OTHER  INSTRUMENTS  AND  LAWS.  The  execution  and
delivery of this Agreement and all other documents and  instruments  executed or
to be executed by Seller pursuant to this Agreement, and the consummation of the
transactions  contemplated  hereby and thereby,  will not (i)  conflict  with or
result in any  violation or breach of or default  under any provision (a) of the
Organizational  Documents,  or (b) of any  mortgage,  indenture,  trust,  lease,
partnership or other agreement or other instrument,  permit, concession,  grant,
franchise or license to which Seller is a party or the Assets or the Business is
subject,  the result of which,

                                       7




<PAGE>



with respect to items identified in clause (b), would (either individually or in
the aggregate)  have a Material  Adverse  Effect on the Business,  or (c) of any
judgment,  order, decree, statute, law, ordinance, rule or regulation applicable
to Seller,  the  Business or the Assets,  the result of which,  with  respect to
items identified in clause (c), would (either  individually or in the aggregate)
have a Material  Adverse Effect on the Business or a material  adverse effect on
the transactions contemplated hereby, or (ii) result in the creation of any Lien
(other than a Permitted Lien) on the Assets.

     3.4   GOVERNMENTAL  AUTHORIZATIONS AND  CONSENTS.  Except  as set  forth on
Schedule  3.4,  no  consents,  licenses,  approvals  or  authorizations  of,  or
registrations  or declarations  with, any Governmental  Authority,  or any third
party,  are  required to be obtained  or made by Seller in  connection  with the
execution, delivery, performance, validity and enforceability of this Agreement,
other than (a) a filing with the Federal Trade  Commission and the Department of
Justice  under  the  HSR  Act,  and (b)  other  consents,  licenses,  approvals,
authorizations,  registrations or declarations, where the failure to obtain such
would not have a Material  Adverse Effect on the Business or a material  adverse
effect on the transactions contemplated hereby.

     3.5   NO VIOLATIONS.  Except as set forth on Schedule 3.5, Seller is not in
violation of any term of its  certificate  of  incorporation  or bylaws or other
charter documents or, to its knowledge, any mortgage,  indenture,  instrument or
agreement relating to indebtedness for borrowed money or of any judgment, decree
or order which names Seller, or of any term of any other Material Contract which
is among the Assets,  which  violation,  either  individually or when aggregated
with all other such  violations,  would have a  Material  Adverse  Effect on the
Business.   Seller  is  not  in  violation,  of  any  law,  ordinance,  rule  or
governmental  regulation  applicable to the Business or any of the Assets, which
violation,   either   individually  or  when  aggregated  with  all  other  such
violations, would have a Material Adverse Effect on the Business.

balance sheet and the related unaudited  statement of operations of the Business
as of and for the year ended June 30, 1999 and (b) the  unaudited  balance sheet

the  Business  as of and for the  ten-month  period  ended  April 30, 2000 (such

as the  "Financial  Statements").  The Financial  Statements  were prepared on a
basis  consistent  with  generally  accepted  accounting  principles and present
fairly in all material  respects the  financial  condition of the Business as of
the dates thereof and the results of its  operations for the periods then ended,
except that the April  Financial  Statements  were prepared on an interim basis,
are subject to normal year-end adjustments.

     3.7   ABSENCE OF CERTAIN CHANGES OR EVENTS.

          (a)    Except as set forth in Schedule 3.7, since April 30, 2000,  (1)

is not in the usual and  ordinary  course of business  and (2) there has been no
Material  Adverse  Effect on the Business,  and, to the knowledge of the Seller,
there has occurred no event that, with the passage of time, is reasonably likely
to result in a Material Adverse Effect on the Business.

                               COVENANTS OF BUYER

     6.1   CONFIDENTIALITY. At all times prior to the Closing, Buyer shall  hold
in strict  confidence,  and shall cause each of its Affiliates to hold in strict
confidence,  all documents and information  obtained with respect to Seller.  At
all times prior to the Closing,  Buyer shall not permit any of such documents or
information  to be  improperly  utilized or to be  disclosed  or conveyed to any
other  person  or  entity,  and Buyer  shall  comply  in all  respects  with the
provisions  of the  Confidentiality  Agreement  between  Seller and Buyer  dated
January  26,  2000  (the  "Confidentiality  Agreement").  Without  limiting  the
generality of the foregoing,  and except as required by law or pursuant to valid
legal  process,  Buyer shall not contact any  customers  or  employees of Seller
without the prior consent of an officer of Seller.

     6.2   INVESTIGATION.  In conducting its review of the Business, Buyer shall
not interfere in any material  respect with the Business or with the performance
of their duties by Seller's employees.  Buyer shall use commercially  reasonable
efforts to complete  its due  diligence  within one (1) week of the date of this
Agreement.

     6.3   INSURANCE. Buyer shall use commercially  reasonable efforts to obtain
and  continuously  maintain,  from the Closing Date until the  expiration of the
representations,  warranties and covenants  pursuant to Section 12.1,  insurance
policies  with respect to the Business and the Assets on terms and with coverage
no less  favorable  than those  maintained by Buyer in  connection  with Buyer's
other businesses.

     6.4   EMPLOYEES.

          (a)    Buyer  shall  offer  employment to (i) each  Employee listed on
Schedule 3.17 who is actively at work for the Business  immediately prior to the
Closing Date ("Active Employees"), and (ii) to each Employee who is not actively
at work on the Closing  Date due solely to  authorized  leave of  absence,  sick
leave, short or long-term disability leave or military leave and who, within 180
days  after  the  commencement  of  the  leave,  returns  to  active  employment
immediately following such absence ("Inactive Employees"). An Employee's date of
hire by Buyer shall, in the case of an Active Employee, be the Closing Date, and
in the case of an  Inactive  Employee,  on the date that such  individual  first
reports to work with Buyer.  Active Employees and Inactive  Employees who accept
Buyer's offer of employment and who become  employees of Buyer shall be referred
to as "Transferred Employees." Seller agrees to facilitate the transition of the
Employees  to  Buyer's   employment  to  the  extent  permitted  by  law,  which
facilitation  shall  include,  without  limitation,   affording  Buyer  and  its
representatives reasonable opportunities to discuss with the Employees terms and
conditions  of  employment  with  Buyer.  Seller  will not  take,  or cause  any
affiliate to take, any action that would impede, hinder,  interfere or otherwise
compete with Buyer's effort to hire any Employee.

          (b)    Buyer shall assume all liabilities of Seller to the Transferred
Employees  of the  Business  with  respect to accrued  vacation and sick days or
similar  days off by means of a credit to such  Employee  of the  Business of an
equal  number of accrued days off under  Buyer's

                                       18




<PAGE>



benefit  plans  (except to the extent  Seller does not credit its  employees for
such number or type of days under its benefit  plans,  in which case Buyer shall
pay the  Employee of the  Business  the value of such  accrued  days off in cash
within 30 days of Closing).  Nothing herein shall restrict Buyer in the exercise
of its independent business judgment, as to the terms and conditions under which
such  employment  with  Buyer  shall be offered  the  duration  of such  offered
employment,  the basis on which such offered  employment  is  terminated  or the
compensation  or benefits  offered to Employees of the Business.  Nothing herein
shall be  deemed to  constitute  an  agreement  to employ  any  Employee  of the
Business for any specific length of time. Seller shall be solely responsible for
any and all severance  commitments or obligations of Seller (including retention
incentive  agreements)  existing as of the Closing  Date except with  respect to
severance  obligations  (and  not any  other  obligations  under  any  retention
incentive agreements) for Transferred Employees of the Business who are employed
by the Buyer for at least 60 days after the Closing Date.

          (c)    Seller  shall  be  responsible  for  any  continuation of group
health coverage required under Section 4980B of the Code or Sections 601 through
608 of ERISA with respect to (i) any Employee or any qualified  beneficiary  (as
defined  in  Section  4980B  of the  Code)  of any such  Employee  who  incurs a
qualifying  event  (as  defined  in  Section  4980B of the  Code)  prior to such
Employee's date of hire by Buyer,  including any such qualifying  event incurred
by reason of the employee's  termination  of employment by Seller,  and (ii) any
Transferred  Employee or any qualified  beneficiary (as defined in Section 4980B
of the Code) of any such Transferred  Employee who incurs a qualifying event (as
defined in Section  4980B of the Code)  after  such  employee's  date of hire by
Buyer;  PROVIDED,  HOWEVER, that Seller's  responsibility for providing coverage
for  Transferred  Employees  and  qualified  beneficiaries  of such  Transferred
Employees  shall  terminate  upon the  adoption by Buyer of a group  health plan
under which Transferred Employees and their qualified beneficiaries are covered.
Buyer shall  reimburse  Seller for all costs  incurred by Seller in covering all
Transferred  Employees and qualified  beneficiaries of such Transferred Employee
under  Seller's group health plan,  including,  without  limitation,  applicable
premiums  for such  coverage  and  administrative  costs  associated  with  such
coverage.  Reimbursement  payments pursuant to this Section 6.4(c) shall be made
on a monthly  basis by Buyer to Seller  within ten (10) days  following  Buyer's
receipt of notice from Seller of the amount due to satisfy Buyer's reimbursement
obligation.

          (d)    Seller  acknowledges  that  on  and  after the Closing Date the
account balances of Transferred Employees shall be distributable from the Seller
401(k) Plan in accordance  with Section  401(k)(10) of the Code.  Neither Seller
nor Seller  401(k) Plan shall place any  Transferred  Employee's  plan loan into
default  or  declare a  default  with  respect  to any plan loan so long as such
individual  transfers  his or her account  balance under the Seller 401(k) Plan,
together  with the note  evidencing  the plan  loan,  to the Buyer  401(k)  Plan
through  a  direct  rollover  on  or as  soon  as  administratively  practicable
following the Closing Date. Buyer shall amend the Buyer's 401(k) Plan and Seller
shall and the Seller 401(k) Plan to the extent  necessary in order to effectuate
the transactions  contemplated  under this paragraph (d). Seller and Buyer shall
cooperate  with each other (and cause the trustees of the Seller 401(k) Plan and
the Buyer's  401(k)  Plan to  cooperate  with each  other)  with  respect to the
rollover of the distributions to the affected Transferred Employees.

liability  for  Taxes,  or (3) any audit,  examination  or other  proceeding  in
respect of Taxes ("Tax Data"). Such cooperation shall include without limitation

on a mutually  convenient basis for all reasonable  purposes,  including without
limitation, to provide explanations and background information and to permit the
copying  of  books,  records,  schedules,  workpapers,  notices,  revenue  agent
reports, settlement or closing agreements and other documents containing the Tax
Data ("Tax Documentation").  If a third party is retained in connection with any
review hereunder,  the party retaining such third party shall be responsible for
any fees and expenses of such third party.

          (b)    The Tax Data and the Tax Documentation shall be  retained until
one  year  after  the  expiration  of all  applicable  statutes  of  limitations
(including extensions thereof);  PROVIDED,  HOWEVER, that in the event an audit,
examination,  investigation or other proceeding has been instituted prior to the
expiration  of an  applicable  statute  of  limitations  the  Tax  Data  and Tax
Documentation  relating  thereto  shall  be  retained  until  there  is a  final
determination thereof (and the time for any appeal has expired).

     6.6   FINANCING.  Buyer shall use commercially reasonable  efforts to enter
into binding commitment letters with one or more financial institutions pursuant
to which  credit  at least  equal to  66-2/3%  of the  Purchase  Price  shall be

relating thereto. Such reasonable access (A) shall include,  without limitation,

relating to the LinkSat Receivables  (including without  limitation,  access for

discovery)  and any  copies of such  documents  as the Seller  shall  reasonably
request,  and (B)  shall be  provided  to  Seller  free of  charge  (other  than
reasonable   travel  related  expenses  for  Buyer's  employees  and  reasonable
duplication charges).

                                   ARTICLE 10

                              RESTRICTIVE COVENANTS

     10.1  NON-COMPETITION. Neither Seller or any of its Affiliates shall, for a
period of three years after the Closing Date,  directly or indirectly,  anywhere
in the United  States,  separately  or  together  with any other  persons,  own,
manage, operate,  control, invest or acquire an interest in, or otherwise engage
or participate (whether as a proprietor, partner, stockholder, member, director,
officer, employee, consultant, joint venturer, investor, sales representative or
other  participant)  in any business,  activity or enterprise that competes with
any  primary  aspect of the  Business  or any  primary  aspect  of the  Business
conducted by Buyer or any of its  subsidiaries  as conducted on the Closing Date
(collectively,  "Competitive Activities");  PROVIDED that this Section shall not
prohibit the Seller from  engaging in any  Competitive  Activities to the extent
that Seller is  acquired by a Person that is engaged or becomes  engaged in such
Competitive  Activities,  or, directly or indirectly,  acquires a Person that is
engaged, at the time of such acquisition,  in a Competitive  Activity or becomes
engaged,  after such acquisition,  in a Competitive  Activity;  provided further
that,  to the extent  such  acquired  Person  becomes  engaged in a  Competitive
Activity,  Seller  shall not  transfer  any  know-how  relating  primarily  to a
Competitive Activity to such acquired Person.

     10.2  NON-SOLICITATION   OF  EMPLOYEES.   Neither  Seller  or  any  of  its
affiliates  shall, for a period of three years after the Closing Date,  directly

solicit any Transferred  Employee of Buyer or any of its  subsidiaries or induce
nor  attempt to induce any such  employee  to leave his or her  employment  with
Buyer or any of its  subsidiaries;  PROVIDED  that  this  Section  shall  not be
violated by virtue of any  solicitations by recruiters or other agents acting on
behalf  of Buyer so long as Buyer  does not hire any  Transferred  Employees  so
solicited by such recruiters or agents.

     10.3  ACKNOWLEDGMENTS.  Seller  acknowledges that, in view of the nature of
the Business and the business  objectives  of Buyer in acquiring  the assets and
the goodwill of the Business,  and the  consideration  paid under this Agreement
therefor, the restrictions contained in this Article 10 are reasonably necessary
to protect the legitimate  business interests of Buyer and any violation of such
restrictions will result in irreparable injury to Buyer and its subsidiaries for
which  damages will not be an adequate  remedy.  Seller  therefore  acknowledges
that, if any such restrictions are violated or threatened to be violated,  Buyer
shall be  entitled,  in  addition  to all other  rights and  remedies  as may be
provided by law, to specific performance,  injunctive and other equitable relief
to prevent or  restrain a breach of this  Agreement,  without the  necessity  of
showing any actual damage or posting bond or furnishing other security.

          (a)    Subject  to the  provisions  of Section 12.1 hereof relating to
the  survival  of  representations  and  warranties  and the  other  limitations
contained herein, from and after the Closing, Seller agrees to indemnify, defend
and hold harmless  Buyer and its  Affiliates,  officers,  directors,  employees,

amount of all claims,  losses,  liabilities,  damages,  deficiencies,  costs and
expenses,  including  without  limitation,  losses  resulting  from the defense,
settlement  and/or  compromise  of a  claim  and/or  demand  and/or  assessment,
reasonable  attorneys',  consultants',  accountants' and expert witnesses' fees,

of the amount of any insurance proceeds  recoverable and net of any tax benefit)
and  arising  out of or  relating  to: (i) all  Excluded  Liabilities;  (ii) any
misrepresentation  or breach of any representation or warranty made by Seller in
this Agreement or any other  document and instrument  executed or to be executed
pursuant to this Agreement;  and (iii) any breach of any covenant,  agreement or
obligation of Seller contained in this Agreement. Notwithstanding the foregoing,
damages shall constitute Losses for the purpose of this Section 12.2 only to the
extent of the direct damages incurred (excluding  consequential damages, whether
or not foreseeable).

          (b)    Seller  shall  not  be required to indemnify Buyer  Indemnitees
with respect to any claim for  indemnification  resulting from or arising out of
matters  described above pursuant to Section  12.2(a)(ii),  unless and until the
aggregate  amount of all claims  against Buyer  Indemnitees  exceeds two percent
(2%) of the  Purchase  Price and then only to the extent such  aggregate  amount
exceeds  one  percent  (1%) of the  Purchase  Price.  Claims  thereafter  may be
asserted  regardless  of  amount;  PROVIDED,   HOWEVER,  that  Seller's  maximum
liability to Buyer Indemnitees under this Section 12.2 shall not exceed:

                 (1)    in the case of Five  Year Matters,  100% of the Purchase

<PAGE>

PROVIDED,  FURTHER,  that in no event shall Seller's maximum liability hereunder

     12.3  INDEMNITY BY BUYER.  Subject to the provisions of Section 12.1 hereof
relating  to the  survival  of  representations  and  warranties  and the  other
limitations  contained  herein,  from and after  the  Closing,  Buyer  agrees to
indemnify,  defend and hold  harmless  the  Seller  and each of its  Affiliates,
officers,  directors,  employees,  agents and  stockholders  (collectively,  the
"Seller  Indemnitees")  against the net amount of all Losses  incurred by any of
the Seller  Indemnitees (after deduction of the amount of any insurance proceeds
recoverable  and net of any tax  benefit) and arising out of or relating to: (i)
any  Assumed   Liabilities;   (ii)  any   misrepresentation  or  breach  of  any
representation or warranty made by Buyer in this Agreement; and (iii) any breach
of any covenant,  agreement or obligation of Buyer  contained in this Agreement.
Notwithstanding  the foregoing,  damages shall constitute Losses for the purpose
of  this  Section  12.3  only  to the  extent  of the  direct  damages  incurred
(excluding consequential damages, whether or not foreseeable).

     12.4  DEFENSE OF THIRD-PARTY  ACTIONS. If either a Buyer Indemnitee, on the
one hand, or a Seller Indemnitee, on the other hand (the "Indemnitee"), receives
notice or otherwise  obtains  knowledge of any matter or any  threatened  matter
that may give rise to an  indemnification  claim  against  the other  party (the
"Indemnifying  Party"),  then  the  Indemnitee  shall  promptly  deliver  to the
Indemnifying Party a written notice describing such matter in reasonable detail.
The timely delivery of such written notice by the Indemnitee to the Indemnifying
Party shall not be a condition  precedent  to any  liability  on the part of the
Indemnifying  Party under this Article 12 with  respect to such matter,  except,
and only to the  extent  of,  any actual  prejudice  to the  Indemnifying  Party
resulting  from such failure to make timely  delivery.  The  Indemnifying  Party
shall have the right,  at its  option to assume the  defense of any such  matter
with its own counsel, but only if the Indemnifying Party  simultaneously  agrees
to indemnify the Indemnitee for such matter. If the Indemnifying Party elects to
assume the defense of and indemnification for any such matter, then:

          (a)    notwithstanding  anything  to  the  contrary contained in  this
Agreement,  the  Indemnifying  Party shall not be  required to pay or  otherwise
indemnify the Indemnitee  against any attorneys' fees or other expenses incurred
on  behalf of the  Indemnitee  in  connection  with such  matter  following  the
Indemnifying Party's election to assume the defense of such matter;

          (b)    the Indemnitee shall make  available to the Indemnifying  Party
all books,  records and other  documents and materials that are under the direct
or indirect control of the Indemnitee or any of the Indemnitee's agents and that
the Indemnifying Party considers  necessary or desirable for the defense of such
matter;

                                       29




<PAGE>



          (c)    the  Indemnitee  shall  execute  such  documents and  take such
other actions as the Indemnifying  Party may reasonably  request for the purpose
of  facilitating  the defense of, or any  settlement,  compromise  or adjustment
relating to, such matter;

          (d)    the  Indemnitee  shall otherwise  fully cooperate as reasonably
requested by the Indemnifying Party in the defense of such matter; and

          (e)    the Indemnitee  shall not admit any liability  with  respect to
such matter.

If  the   Indemnifying   Party   elects  not  to  assume  the   defense  of  and
indemnification  for  such  matter,  then  the  Indemnitee  shall  proceed  with
reasonable diligence to defend such matter with the assistance of Cooley Godward
LLP (in the case of the Seller) or Proskauer  Rose LLP (in case of the Buyer) or
other counsel  reasonably  satisfactory  to the  Indemnifying  Party;  PROVIDED,
HOWEVER, that the Indemnitee shall not settle, adjust or compromise such matter,
or admit any  liability  with respect to such matter,  without the prior written
consent of the Indemnifying Party, such consent not to be unreasonably  withheld
or delayed.

     12.5 SUBROGATION.  To the  extent that the  Indemnifying  Party makes or is
required to make any indemnification payment to the Indemnitee, the Indemnifying
Party shall be entitled to exercise,  and shall be subrogated to, any rights and
remedies (including rights of indemnity, rights of contribution and other rights
of recovery) that the Indemnitee or any of the Indemnitee's  affiliates may have
against any other person with respect to any Losses,  circumstances or matter to
which such  indemnification  payment is  directly  or  indirectly  related.  The
Indemnitee shall permit the Indemnifying Party to use the name of the Indemnitee
and the  names  of the  Indemnitee's  Affiliates  in any  transaction  or in any
proceeding  or other matter  involving  any of such rights or remedies;  and the
Indemnitee  shall take such  actions as the  Indemnifying  Party may  reasonably
request for the purpose of enabling  the  Indemnitee  to perfect or exercise the
Indemnifying Party's right of subrogation hereunder.

     12.6 EXCLUSIVITY.  The right of each party hereto to assert indemnification
claims and receive indemnification payments pursuant to this Article 12 shall be
the sole and exclusive  right and remedy  exercisable by such party with respect
to any  breach by the other  party  hereto of any  representation,  warranty  or
covenant  or  failure  to pay or  perform  any  Assumed  Liability  or  Excluded
Liability, as applicable.

     12.7 RETENTION OF RECORDS. From and after the date of this Agreement, Buyer
and Seller shall preserve all books, records and other documents,  materials and
information relevant to the representations,  warranties and covenants set forth
in this Agreement for a period of six years following the date of this Agreement
or for such longer period as the rights of the parties hereunder may exist.

     12.8 NO  RESCISSION.  Neither Buyer nor Seller shall be entitled to rescind
the  purchase  of the  Business  and the Assets by virtue of any  failure of any
party's representations and warranties herein to have been true or any breach of
any party's obligations hereunder.
