foreign corporation or other entity and is in good standing under the laws of
each jurisdiction in which the conduct of its business or the ownership of its

except where the failure to be so qualified would not have a Material Adverse
Effect on the PRC Companies taken as a whole.  Schedule 3.1 correctly lists the
current directors and executive officers of each PRC Company as of the date

capital stock of PRC are held in treasury, and there are no other issued or
outstanding equity securities of PRC and no other issued or outstanding

options, subscriptions, warrants, rights or any other obligations.

  Section 3.3. Ownership of PRC Shares.  Seller is the record and beneficial
owner of the PRC Shares, which are free of any lien, security interest, charge,
encumbrance or claim whatsoever.  At the

of the PRC Shares, free of any lien, security interest, charge, encumbrance or
claim whatsoever.

  Section 3.4. PRC Subsidiaries.  Schedule 3.4 sets forth the authorized
capital stock and the record ownership of the outstanding shares of capital
stock of each of the PRC Subsidiaries, and a brief summary of each PRC
Subsidiary's business.  PRC's ownership of shares of the capital stock of the
PRC Subsidiaries as shown on Schedule 3.4 is free of any lien, security
interest, charge, encumbrance or claim whatsoever.  PRC does not have any
Subsidiaries other than the PRC Subsidiaries.  All of the outstanding shares of
capital stock of each of the PRC Subsidiaries have been validly issued and are
fully paid and nonassessable and were issued in conformity with applicable
Laws.  Other than as set forth in Schedule 3.4, there are no other issued or
outstanding equity securities of any of the PRC Subsidiaries and there are no
other issued or outstanding securities of any of the PRC Subsidiaries
convertible or exercisable at any time into equity securities of any of the PRC
Subsidiaries.  None of the PRC Subsidiaries is subject to any commitment or
obligation that would require the issuance or sale of additional shares of its
capital stock at any time under options, subscriptions, warrants, rights or any
other obligations.  Except as described in Schedule 3.4, PRC does not own any
equity securities of any Person that is not a Subsidiary.

  Section 3.5. Execution and Effect of Agreement.  Each of Seller and Seller's
Parent has all necessary corporate power and



                                     19

products designed, manufactured, assembled, repaired, maintained, delivered or
installed or services rendered prior to or on the Closing Date, except where
such act, omission or occurrence would not have a Material Adverse Effect on

now conducted by such PRC Company.  Except as disclosed in Schedule 3.35,
Seller has no knowledge of any proposed or threatened termination of any
material personnel or facility security clearance relating to the business of
any PRC Company (whether or not such clearance is collateral or special
access).

                                       56
<PAGE>   65

to cause any representation or warranty contained in this Agreement to be
untrue or inaccurate in any material respect at any time from the date of this
Agreement to the Closing Date and (ii) any failure of Seller to comply with or
satisfy, in any material respect, any covenant, condition or agreement to be
complied with or satisfied by it under this Agreement.  No such notification
shall affect the representations or warranties of Seller or the conditions to
Buyer's obligations hereunder.

  Section 5.10.  Noncompetition.

   (a)  Restrictions on Competitive Activities.  Seller agrees that after the
Closing Buyer and PRC shall be entitled to the goodwill and going concern value
of the business of the PRC Companies and to protect and preserve the same to
the maximum extent permitted by Law.  Seller also acknowledges that its
management contributions to the business of the PRC Companies have been
uniquely valuable and involve proprietary information that would be
competitively unfair to make available to any competitor of the PRC Companies.
For these and other reasons and as an inducement to Buyer to enter into this
Agreement, Seller agrees that for a period of three years after the date hereof
neither Seller nor any of Seller's Affiliates will, directly or indirectly, for
its own benefit or as agent for another carry on or participate in the
ownership, management or control of, or the financing of, or allow its name or
reputation to be used in or by any other present or future business enterprise
that competes with Buyer or the PRC Companies in activities in which any of the
PRC Companies is engaged as of the Closing Date (a "Competing Business").



                                     57
<PAGE>   66

   (b)  Exceptions.  Nothing contained herein shall limit the right of Seller
as an investor to hold and make investments in securities of any corporation or
limited partnership that is registered on a national securities exchange or
admitted to trading privileges thereon or actively traded in a generally
recognized over-the-counter market, provided Seller's equity interest therein
does not exceed 5% of the outstanding shares or interests in such corporation
or partnership.  Notwithstanding any provisions of this Section 5.10 to the
contrary, if Seller's Parent or any of its Affiliates acquires any Person that
is engaged in a Competing Business, Seller's Parent and its Affiliates shall
not be deemed to be in violation of this Section 5.10 provided that (i) the
Competing Business represents less than one-third of the gross revenues of the
acquired Person for the acquired Person's most recent completed fiscal year and
(ii) Seller's Parent or its Affiliates use reasonable and diligent efforts to
divest the operations of such Competing Business subsequent to such
acquisition.

   (c)  Restrictions on Soliciting Employees.  In addition, to protect Buyer
against any efforts by Seller or any of Seller's Affiliates to cause employees
of the PRC Companies as of the date of this Agreement to terminate their
employment, Seller agrees that for a period of three years following the
Closing Date, neither Seller nor any of its Affiliates will, directly or
indirectly (i) induce any employee of the PRC Companies as of the date of this
Agreement with a then current compensation of more than $50,000 annually to
leave any of the PRC Companies or to accept any other





                                      58
<PAGE>   67

employment or position, or (ii) assist (other than normal employment
recommendations) any other Person in hiring any such employee.

   (d)  Special Remedies and Enforcement.  Seller recognizes and agrees that a
breach by Seller or any of its Affiliates of any of the covenants set forth in
this Section 5.10 could cause irreparable harm to Buyer, that Buyer's remedies
at law in the event of such breach would be inadequate, and that, accordingly,
in the event of such breach a restraining order or injunction or both may be
issued against Seller and its Affiliates, in addition to any other rights and
remedies which are available to Buyer.  If this Section 5.10 is more
restrictive than permitted by the Laws of the jurisdiction in which Buyer seeks
enforcement hereof, this Section 5.10 shall be limited to the extent required
to permit enforcement under such Laws.

  Section 5.11.  Nondisclosure of Proprietary Data.  Neither Seller nor any of
its Affiliates or representatives shall, at any time, make use of, divulge or
otherwise disclose, directly or indirectly, any trade secret or other
proprietary data (including, but not limited to, any customer list, record or
financial information) concerning the business or policies of the PRC Companies
that Seller or any Affiliate or representative of Seller may have learned as a
shareholder, employee, officer or director of the PRC Companies.  In addition,
except as required by Law or legal process neither Seller nor any of its
Affiliates or representatives shall make use of, divulge or otherwise disclose,
directly or indirectly, to persons other than Buyer, any confidential





                                     59
<PAGE>   68

information concerning the business or policies of the PRC Companies which may
have been learned in any such capacity.

  Section 5.12.  No Solicitation.  From the date of this Agreement to the
Closing Date or earlier termination of this Agreement, Seller and its
Affiliates and representatives will not directly or indirectly make, entertain,
solicit or encourage inquiries or proposals, enter into or conduct discussions,
or negotiate or enter into an agreement with any party other than Buyer for the
divestiture of any or all of the PRC Companies or their respective assets,
whether by way of an asset or stock sale, partnership, joint venture, merger,
consolidation or other transaction.

  Section 5.13.  Novations.  In the event any Governmental Entity requires
Government Contract Novations, Seller and Seller's Parent shall cooperate with
the PRC Companies to promptly obtain such Government Contract Novations and
shall execute the novation agreements required by any Governmental Entity.

                                   ARTICLE VI

<PAGE>   70

Seller's Parent and its Subsidiaries (other than Subsidiaries that are PRC
Companies) to obtain full and complete releases on each of the Guarantees
referenced in the preceding sentence, which reasonable efforts shall include
but not be limited to providing any financial information about Buyer
reasonably requested by the Persons for whose benefit the respective Guarantees

  Section 6.5. Certain Employee Benefit Matters.

   (a)   Buyer shall take all action required or appropriate to cause each of
the PRC Companies to fulfill its obligations under all Benefit Arrangements,

   (b)   Buyer acknowledges that certain Employees of the PRC Companies may be
entitled to benefits under the Incentive Compensation Plans, the Special
Severance Plans or other Benefit Arrangements involving severance or

Plans and such other Benefit Arrangements in respect of the Employees and agree
to pay any benefits to the Employees that the Employees may be entitled to
receive under the Incentive Compensation Plans, the Special Severance Plans and

substantially comparable to those provided under the Employee Benefit Plans and
Benefit Arrangements as in effect immediately prior to the Closing Date for the
benefit of all eligible Employees and their dependents.  Nothing in this
Section 6.5 shall obligate Buyer or any PRC Company to sponsor or maintain any
specific Employee Benefit Plan or Benefit Arrangement for any period of time
after the Closing Date.


  Section 6.6. Preservation of and Access to Certain Information After Closing.
Except as prohibited or limited by Law, Buyer shall cause the PRC Companies,

and determination of the Proposed Net Asset Amount and the Final Net Asset
Amount (and the resolution of any





                                       63
<PAGE>   72

disputes in respect thereof), or the preparation of any Tax Returns for the
Affiliated Groups, or in connection with or in anticipation of any audit by any
federal, state or local Tax Authorities of the Affiliated Groups.  From and

provided, however, that Buyer shall not destroy or dispose of such books and
records without giving notice to Seller and Seller's Parent of such pending
destruction or disposal and offering Seller and Seller's Parent the right and
opportunity to copy such books and records.

or satisfy, in any material respect, any covenant, condition or agreement to be

Returns that include the result of the Section 338(h)(10) Election) of the PRC
Companies due after the date hereof for any taxable year or taxable period
ending on or before the Closing Date, including any taxable period that ends at
the end of the Closing Date as a result of the Section 338(h)(10) Election (a
"Pre-Closing Period").

   (b)  Subject to the provisions of Section 11.1(c), Seller's Parent and Seller
shall pay and be responsible for, shall indemnify and hold harmless Buyer and
the PRC Companies (the "Buyer Group") against, and shall be entitled to all
refunds and credits of, (i) Income Taxes and all foreign Taxes (together with
reasonable attorneys' fees and any legal or other expenses for investigating or
defending any actions with respect to such Taxes) with respect to the PRC
Companies for any Pre-Closing Period, including any liability for Income Taxes
and all foreign Taxes arising out of the inclusion of any of the PRC Companies
in any Consolidated Returns, and further including any liability for Income
Taxes arising as a result of the Section 338(h)(10) Election, and (ii) all
Taxes (together with reasonable attorneys' fees and any legal or other expenses
for investigating or defending any actions with respect to Taxes) with respect
to Seller's Parent and any member of the Affiliated Groups (other than the PRC
Companies) for all taxable periods whatsoever.  Buyer shall, promptly after the
receipt thereof, remit to Seller's Parent any Income Tax or foreign Tax refund
received by Buyer, Buyer's Parent or any of the PRC Companies to the extent
such refund relates to a Pre-Closing Period.  Seller's Parent or Seller shall
promptly, after the receipt thereof, remit to Buyer any Tax refund received by
Seller's Parent or Seller to the extent such refund relates to any Tax paid by
or on behalf of the PRC Companies, other than an Income Tax or foreign Tax
refund related to a Pre-Closing Period.  Notwithstanding the provision of this
Section 11.1(b), neither Seller nor Seller's Parent shall be responsible for or
shall be



                                       76
<PAGE>   85

required to indemnify or hold harmless Buyer or any of the PRC Companies for
any Taxes that are reimbursed under any contracts of any of the PRC Companies;
provided, however, that Buyer shall cause the appropriate PRC Company to use
its reasonable best efforts to seek reimbursement for such Taxes under the
applicable contract.

   (c)   No member of the Buyer Group shall be entitled to indemnification
under Section 11.1(b) for any Taxes for which a reserve with respect to such
Taxes is included in or taken into account in the calculation or determination
of the Final Net Asset Amount, except for the Taxes exceeding the amount of
such reserve.

     (d)  Buyer shall be responsible for, and shall indemnify and hold harmless
Seller and Seller's Parent against, (i) the Taxes described in Section 12.3,
(ii) the timely preparation and filing of all Tax Returns of the PRC Companies
for any taxable year or taxable period beginning after the Closing Date (the
"Post-Closing Period"), and (iii) the preparation and filing of all Tax Returns
required to be filed by any of the PRC Companies after the Closing Date other
than those Tax Returns for Income Taxes and all foreign Taxes described in
Section 11.1(a).

   (e)   Buyer shall pay and be responsible for, shall indemnify and hold
harmless Seller and Seller's Parent against, and shall be entitled to all
refunds and credits of, all Taxes (together with reasonable attorneys' fees and
any legal or other expenses for investigating or defending any actions with
respect to Taxes) with respect to the PRC Companies for any Post-Closing
Period.



                                       77
<PAGE>   86



   (f)   Subject to the provisions of Section 11.2, if, for any federal, State
or local Income Tax or foreign Tax purpose, a taxable year or taxable period of
any of the PRC Companies which begins before the Closing Date and ends after
the Closing Date (a "Bridge Period") does not terminate on the Closing Date,
and Buyer has the responsibility to pay Taxes for all or a portion of the
Bridge Period, the parties hereto will, to the extent permitted by applicable
Law, elect with the relevant Tax Authority to treat the portion of the Bridge
Period on or before the Closing Date (a "Seller Period") for all purposes as a
short taxable period ending as of the close of the Closing Date and such short
taxable period shall be treated as a Pre-Closing Period for purposes of this
Agreement and the portion of the Bridge Period after the Closing Date (the
"Buyer Period") shall be treated as a Post-Closing Period for purposes of this
Agreement.  In any case where applicable Law does not permit such an election
to be made, then, for purposes of this Agreement, Income Taxes and all foreign
Taxes for the Bridge Period shall be allocated between the Seller Period and
the Buyer Period using an interim-closing-of-the-books method assuming that
such taxable period ended at the close of business on the Closing Date, except
that exemptions, allowances or deductions that are calculated on an annual
basis (such as the deduction for depreciation) shall be apportioned on a per
diem basis.

   (g)   Buyer shall cause the PRC Companies to prepare and file all Tax
Returns and pay all Taxes due, if any, with respect to the PRC Companies for
any Bridge Period that does not terminate on the Closing Date, for which it is
responsible to pay Taxes in whole





                                       78
<PAGE>   87

or in part, provided that Seller satisfies its obligations as set forth in this
Section 11.1(g).  Seller shall promptly deliver to Buyer work papers relating
to Taxes due for the Seller Period, certified by a duly authorized officer of
Seller, setting forth in detail all information required to complete the
applicable Tax Returns.  Upon notice from Buyer, Seller shall pay to Buyer the
Income Taxes and all foreign Taxes for the Seller Period on or before the
second business day prior to the due date for the payment of such Income Taxes
and all foreign Taxes, by wire transfer of immediately available funds to the
account designated by Buyer.  In the event that Seller fails to make the
payments required by this Section 11.1(g) to Buyer prior to the date any
payment for Income Taxes and all foreign Taxes as described in this Section
11.1(g) is due, such required payment shall bear interest from such due date
until paid, at the underpayment rate of interest determined under Section 6621
of the Code.

   (h)   Buyer shall have exclusive control over and responsibility to conduct
any Contest for a Post-Closing Period and for a Bridge Period if the Contest
for a Bridge Period relates solely to the Buyer; provided, however, that Buyer
shall not enter into any agreement in compromise or settlement of such Contest
which could affect a Pre-Closing Period or a Seller Period without the written
consent of Seller.

   (i)   Unless Buyer agrees in writing to waive any claim for indemnification
under Section 11.1(b) with respect thereto, Seller and Seller's Parent shall
have exclusive control over and responsibility to conduct any Contest for a
Pre-Closing Period and



                                       79
<PAGE>   88

for a Bridge Period if the Contest for a Bridge Period relates solely to the
Seller Period; provided, however, that neither Seller not Seller's Parent shall
enter into any agreement in compromise or settlement of such Contest which
could affect a Post-Closing Period or a Buyer Period without the written
consent of Buyer.

   (j)   Buyer shall notify Seller's Parent in writing promptly upon receipt by
any PRC Company of notice of any Contest or assessment relating thereto for
Pre-Closing Period or a Bridge Period.  Failure of Buyer to so notify Seller's
Parent shall not relieve Seller's Parent or Seller from any liability under
this Section 11.1, except to the extent it is proven that Seller's Parent or
Seller suffered actual prejudice in connection with or in defending against a
Contest.  Seller or Seller's Parent shall notify Buyer in writing promptly upon
receipt by Seller or Seller's Parent of notice of any Contest or assessment
relating to a Post-Closing Period or a Bridge Period.

   (k)   Buyer and Seller agree to jointly control and conduct any Contest for
a Bridge Period that relates to both the Seller Period and the Buyer Period.
Seller, Seller's Parent and Buyer agree to cooperate fully with each other with
respect to defending or answering any such Contest and to provide each other
with all materials, information and documents as reasonably requested by the
other.  Neither Buyer, Seller, nor Seller's Parent shall be liable for any
portion of any settlement of any Contest for a Bridge Period that relates to
both the Seller Period and the Buyer Period effected without its written
consent, provided such consent was not unreasonably withheld.





                                       80
<PAGE>   89

  (l)  Except as otherwise provided in this Agreement and subject to the
allocation of liabilities for Taxes, Seller, Seller's Parent and Buyer agree to
cooperate fully with each other with respect to the preparation of all Tax
Returns and with respect to all matters relating to Taxes, and to keep each
other advised as to any issue relating to Taxes which could have a bearing on
such other party's responsibilities hereunder.

   (m)   In any Contest controlled by Seller, Buyer will take, and will cause
each PRC Company to take, such action as Seller may by written notice
reasonably request in connection with such Contest (including the payment of a
Tax preparatory to filing a claim for refund of such Tax; provided that Seller
shall first pay the amount of such Tax to Buyer).

  Section 11.2.  Section 338(h)(10) Election.

   (a)   Seller, Seller's Parent, and each of the PRC Companies agree, if so
directed by the Buyer, to join with Buyer in making an election under Section
338(h)(10) of the Code (and any corresponding elections under state, local or
foreign tax law) (collectively, a "Section 338(h)(10) Election") with respect
to the purchase and sale of the stock of the PRC Companies hereunder.  Seller
will pay any Income Tax, including any liability of the PRC Companies for
Income Tax resulting from the application to it of Treas. Reg. Section
1.338(h)(10)-1(f)(5), attributable to the making of the Section 338(h)(10)
Election (but only to the extent that application causes an increase in taxable
gain resulting from the deemed purchase of assets pursuant to Section 338 of
the Code) and will indemnify the Buyer and the PRC Companies against any
Material



                                       81
<PAGE>   90

Adverse Effect arising out of any failure to pay such Income Tax.  If the
Section 338(h)(10) Election is made, Seller and Seller's Parent will also pay
any state, local or foreign Income Tax (and indemnify Buyer and the PRC
Companies against any Material Adverse Effect arising out of any failure to pay
such Income Tax) attributable to an election under state, local, or foreign law
similar to the election available under Section 338(g) of the Code (or which
results from the making of an election under Section 338(g) of the Code) with
respect to the purchase and sale of the stock of the PRC Companies hereunder.

   (b)   Except as provided below, on or before the date that is 60 days after
the Closing Date, Buyer shall prepare a schedule, in the form of Exhibit C,
which reflects an allocation (the "Allocation") of Buyer's "adjusted grossed-up
basis" and Seller's "deemed sale price" among the Class I, Class II, Class III
and Class IV Assets (as such terms are defined in Section 338 of the Code and
the Department of Treasury regulations thereunder).  Provided the Allocation is
reasonable, Seller's Parent agrees to accept the Allocation.  Buyer shall be
under no obligation to have the Allocation prepared or approved by an
independent appraiser.  Buyer shall be responsible for the preparation of all
forms and filings required to be filed with any Tax Authority to claim the
Section 338(h)(10) Election and Buyer and Seller's Parent shall reflect the
Allocation in all Income Tax returns in which the Section 338(h)(10) Election
is relevant, the effect of which is to treat the purchase of the shares of PRC
by Buyer as the purchase of the assets of PRC by Buyer.  If the Final Net Asset
Amount is not





                                       82
<PAGE>   91

determined within 60 days of the Closing Date, then Exhibit C shall be prepared
promptly after the Final Net Asset Amount is determined.

  Section 11.3.  Indemnification by Buyer.  Buyer agrees to indemnify, defend
and hold harmless Seller, Seller's Parent and their respective directors,
officers, employees, Affiliates, agents, successors and assigns from and
against any and all Losses suffered or incurred by an Indemnified Party
resulting from, related to or arising out of:

   (a)   any inaccuracy in any of the representations and warranties made by
Buyer in this Agreement or in any agreement or certificate delivered pursuant
hereto or in connection herewith;

   (b)   any breach or nonperformance of any of the covenants of Buyer or its
Affiliates contained in this Agreement (including those in Sections 8.1 and
8.2) or in any agreement or document delivered pursuant hereto or in connection
herewith;

   (c)   any Post-Closing Claim, but only to the extent that the Losses
suffered or incurred result from facts and circumstances that occurred after
the Closing Date (excluding Losses suffered or incurred resulting from facts or
circumstances that occur after the Closing Date but which relate to Hazardous
Substances present at properties or facilities of the PRC Companies on the
Closing Date); and

   (d)   any Guarantees (other than those relating to payments under the "PRC
Supplemental Executive Retirement Plan") of Seller's Parent (or any of its
Affiliates) to the extent they were



                                       83
<PAGE>   92

issued for the benefit of Persons doing business with any of the PRC Companies.

To the extent, but only to the extent, that any Loss for which Buyer has
indemnification obligations under Section 11.3(c) arises as a result of any
fact, circumstance or condition that also causes the inaccuracy of any
representation or warranty of Seller, Seller's Parent or PRC contained in this
Agreement or in any agreement or certificate delivered pursuant hereto or in
connection herewith, or otherwise is the basis for an indemnification claim by
Buyer under Section 11.4, Buyer shall not have liability under Section 11.3(c).

  Section 11.4.  Indemnification by Seller and Seller's Parent.  Seller and
Seller's Parent agree, jointly and severally, to indemnify, defend and hold
harmless Buyer, the PRC Companies and their respective directors, officers,
employees, Affiliates, agents, successors and assigns from and against any and
all Losses suffered or incurred by an Indemnified Party resulting from,
relating to, or arising out of:

   (a)   any inaccuracy in any of the representations and warranties made by
Seller, Seller's Parent or the PRC Companies in this Agreement or in any
agreement or certificate delivered pursuant hereto or in connection herewith;

   (b)   any breach or nonperformance of any of the covenants of Seller,
Seller's Parent or the PRC Companies or their Affiliates contained in this
Agreement (including those in Sections 8.1 and 8.2) or in any agreement or
document delivered pursuant hereto or in connection herewith;





                                       84
<PAGE>   93

   (c)   any Pre-Closing Claim (including Pre-Closing Claims listed on, or
arising from matters listed on, Schedules to this Agreement), but only to the
extent that the Losses suffered or incurred result from facts and circumstances
that occurred on or prior to the Closing Date;

   (d)   any divestitures, sales or other dispositions by any PRC Company of
divisions, product lines, businesses, real property or intellectual property
(other than dispositions of Intellectual Property in the ordinary course of
business in connection with the provision of products or services to customers
of the PRC Companies), Subsidiaries and interests in other Persons effected
prior to the Closing Date, whether as a result of breaches of purchase or sales
agreements, under indemnification provisions, under guarantees by a PRC Company
not yet assumed by the purchaser in such divestitures, sales or dispositions,
or otherwise;

   (e) actions taken by Buyer and the PRC Companies after the Closing Date to
bring into compliance with Environmental Laws as in effect at the Closing Date
any violation or noncompliance existing as of the Closing Date, and from Losses
arising from the operations of any PRC Company subsequent to the Closing Date
and prior to the correction of such items of noncompliance as a result of such
violation or noncompliance; provided that, as to Losses arising from the
operations of any PRC Company subsequent to the Closing Date action is taken to
correct such noncompliance reasonably promptly upon discovery of such
noncompliance by Buyer or any of the PRC Companies;





                                       85
<PAGE>   94

   (f)  the following employee benefit matters:  (x) the maintenance of or
contribution to a Pension Plan subject to Title IV of ERISA, or obligation to
contribute to a Multiemployer Plan, by an ERISA Affiliate of any of the PRC
Companies (which ERISA Affiliate is not itself one of the PRC Companies), (y)
any post-retirement medical or life insurance benefits and (z) any "change of
control" or similar payments to be made to Employees of PRC Companies as a
result of the transactions contemplated hereby (other than any such payments
made under plans or Benefit Arrangements assumed by Buyer pursuant to Section
6.5);

   (g)   the "PRC Supplemental Executive Retirement Plan" referred to in
Schedule 3.14 and the Financial Statements; and

   (h)   the conduct of the business of Seller, Seller's Parent and any of its
Affiliates other than the PRC Companies. For purposes of Section 11.4(a), all 
such representations and warranties shall be read as if references therein to 
the materiality to the PRC Companies or any of them of any condition, fact, 
statement, event or act (including without limitation all references to 
"Material Adverse Effects" and "in all material respects") were deleted and 
the effect of any such references were eliminated altogether.  Thus, for 
example: (i) any representation that a statement is true and correct in all 
material respects shall be read as a representation that the statement is true
and correct; (ii) any representation that a condition exists except to the
extent that its failure to exist would not have a Material Adverse Effect on
the PRC Companies shall be read as a representation that such condition
exists; and (iii) any representation that no



                                       86
<PAGE>   95

incidents of a specific nature have occurred that would have a Material Adverse
Effect on the PRC Companies shall be read as a representation that no incidents
of such nature have occurred.

  Section 11.5.  Procedure.

   (a)   Promptly after acquiring knowledge of any claim in respect of which a
party (the "Indemnified Party") may seek indemnification from the other party
(the "Indemnifying Party") hereunder, the Indemnified Party shall give written
notice thereof to the Indemnifying Party describing such claim and demanding
indemnification hereunder.  Notwithstanding the foregoing, failure to provide
the aforementioned notice will not relieve the Indemnifying Party of any
liability that it may have to the Indemnified Party under this Agreement,
except to the extent that (i) such failure to provide notice causes the amounts
paid by the Indemnifying Party to be greater than they would have been had such
notice been given on a reasonably timely basis or (ii) such notice is not
delivered to the Indemnifying Party prior to the expiration of any applicable
survival period under Section 11.6.  The Indemnifying Party will be entitled to
assume control of the defense of any claim, and to settle or compromise such
claim in its discretion, subject to the provisions of Sections 11.5(b) and
11.5(c).  After written notice by the Indemnifying Party to the Indemnified
Party of its election to assume control of the defense of any such action, the
Indemnifying Party shall not be liable to such Indemnified Party hereunder for
any legal expenses subsequently incurred by such Indemnified Party in
connection with the defense thereof.  Notwithstanding anything in this Section
11.5



                                       87
<PAGE>   96

to the contrary, if the Indemnifying Party does not promptly assume control of
the defense of such action as provided in this Section 11.5, the Indemnified
Party shall have the right to defend such action in such manner as it may deem
appropriate at the cost and expense of the Indemnifying Party and the
Indemnifying Party will promptly reimburse the Indemnified Party therefor
(subject, if applicable, to the limitations contained in Section 11.7).  An
Indemnifying Party may, at its option and expense, participate in the defense
of any indemnifiable claim.

   (b)   To the extent that any of the Losses by any of the Persons entitled to
indemnification under Section 11.3 or Section 11.4 relate to facts and
circumstances that occur both prior to and after the Closing, or relate to both
a Pre-Closing Claim and a Post-Closing Claim, then the Indemnifying Party and
the Indemnified Party shall jointly determine at all times thereafter the
actions to be taken with respect to such claims and the control, investigation,
prosecution, defense and settlement thereof.

   (c)  Neither the Indemnifying Party nor the Indemnified Party shall, without
the written consent of the other party, settle or compromise any indemnifiable
claim or permit a default or consent to entry of any judgment.  If a settlement
offer solely for money damages is made by the applicable third party claimant,
and the Indemnifying Party notifies the Indemnified Party in writing of the
Indemnifying Party's willingness to accept the settlement offer and pay the
amount called for by such offer without reservation of any rights or defenses
against the Indemnified Party, the Indemnified Party may withhold its consent
and continue to contest



                                       88
<PAGE>   97

such claim, free of any participation by the Indemnifying Party, and the amount
of any ultimate liability with respect to such indemnifiable claim that the
Indemnifying Party shall have an obligation to pay thereunder (regardless of
the ultimate Loss sustained by the Indemnified Party) shall be equal to the
amount of the settlement offer that the Indemnified Party declined to accept
plus the previously unpaid Losses of the Indemnified Party relating to such
indemnifiable claim through the date of its rejection of the settlement offer.
If the Indemnifying Party makes any payment on any indemnifiable claim, the
Indemnifying Party shall be subrogated, to the extent of such payment, to all
rights and remedies of the Indemnified Party to any insurance benefits or other
claims of the Indemnified Party with respect to such claim.

   (d)   With respect to any claim for which Seller or Seller's Parent is the
Indemnifying Party and for which the Indemnifying Party has assumed control of
the defense, Buyer shall make employees of the PRC Companies reasonably
available to assist the Indemnifying Party in defending such claim, provided
that the costs of providing such assistance are paid by the Indemnifying Party
or, if paid by Buyer or any PRC Company, reimbursed to Buyer or the PRC
Company, as appropriate, by the Indemnifying Party.

   (e)   Any amounts to which an Indemnified Party is entitled under this
Article shall be paid by the Indemnifying Party promptly upon request.


  Section 11.6.  Survival.

   (a)   The representations and warranties contained in or made pursuant to
this Agreement (other than those set forth in



                                       89
<PAGE>   98

Section 3.30) shall survive the Closing as provided in this Section 11.6(a).

on the second anniversary of the Closing Date.  The indemnifications set forth
in Sections 11.1 and 11.2 shall survive until the end of the applicable statute
of limitations period (including extensions) for the Tax matters referenced
therein.  The indemnification set forth in Sections 11.3(a) and 11.4(a) shall
survive for as long as the pertinent representation and warranty survives.  The
indemnification set forth in Sections 11.3(c), 11.4(c) and 11.4(f) shall
survive until the third anniversary of the Closing Date.  The indemnification
set forth in Section 11.4(e) shall survive until the fifth anniversary of the
Closing Date.  The indemnification set forth in Sections 11.3(b), 11.3(d),
11.4(b), 11.4(d), 11.4(g) and 11.4(h) shall survive indefinitely.

  (b)  Except as set forth in this Section 11.6(b), any matter as to which a
claim has been asserted by notice to the other party



                                       90
<PAGE>   99

that is pending or unresolved at the end of any applicable limitation or
survival period, including any matter disclosed in this Agreement, shall
continue to be covered by this Article XI notwithstanding any applicable
statute of limitations or the expiration of any survival period until such
matter is finally terminated or resolved.  Notwithstanding the previous
sentence, the indemnification obligations of Seller and Seller's Parent under
Section 11.4(c) shall not survive beyond the third anniversary of the Closing
Date unless an Action shall have been commenced as of the third anniversary of
the Closing Date.  Notice demanding indemnification for the items set forth on
Schedule 3.10 (as modified under Section 9.2(e)) is acknowledged by the parties
to have been given as of the Closing Date.

  Section 11.7.  Limitations on Indemnification.

   (a) Buyer shall not be required to indemnify Seller, Seller's Parent or any
of their Affiliates under Section 11.3(a) unless the aggregate of all amounts

and, in such event, Buyer shall be responsible for only the amount in excess of
such $1,500,000.  The total indemnification that Buyer may be required to pay
under Section 11.3(a) shall not exceed $100,000,000.

   (b) Seller and Seller's Parent shall not be required to indemnify Buyer or

any Carpal Tunnel Litigation) unless the aggregate of all amounts for which
indemnity would otherwise be payable thereunder exceeds $1,500,000, and, in
such event, Seller and Seller's Parent shall be responsible for only the amount

<PAGE>   101
