The  unaudited  pro  forma condensed consolidated  financial
information  gives effect to the sale of the AI business  as
described  in  Item  2  of this Form  8-K.   The  pro  forma
information   is   based   on   the   historical   condensed
consolidated statements of operation of the Company for  the
nine  months ended March 31, 1999 and the fiscal year  ended
June  30,  1998 as if the AI business had been sold  at  the
beginning  of  each period presented, giving effect  to  the
adjustments   as   reflected  in  the  accompanying   notes.
Additionally, the pro forma condensed consolidated statement
of  financial  position  of the  Company  is  based  on  the
historical  condensed  consolidated statement  of  financial

sold at March 31, 1999, giving effect to the adjustments  as
reflected in the accompanying notes.

The  unaudited  pro  forma condensed consolidated  financial
information  is  not necessarily indicative  of  the  actual
operating  results or financial position of the Company  for
the  periods indicated, nor is it necessarily indicative  of

forma   adjustments   are  based  upon   current   available
information and certain assumptions set forth below  in  the
notes  to  the  unaudited  pro forma condensed  consolidated
financial  statements.  The unaudited  pro  forma  condensed
consolidated  financial  information  should  be   read   in
conjunction   with  the  accompanying  notes  thereto,   the
separate   historical   condensed   consolidated   financial
statements  of  the  Company as of and for  the  nine  month
period  ended  March  31, 1999 which are  contained  in  the
Company's quarterly report on Form 10-Q filed for the  third

ended  June  30, 1998 which are contained in  the  Company's

           NOTES TO UNAUDITED PRO FORMA CONDENSED
             CONSOLIDATED FINANCIAL INFORMATION


NOTE  1  -  PRO  FORMA CONDENSED CONSOLIDATED STATEMENTS  OF
OPERATION

There were no pro forma adjustments necessary to be made  to
the   historical   condensed  consolidated   statements   of
operation of the Company for the nine months ended March 31,
1999 and the fiscal year ended June 30, 1998 to reflect  the
sale  of  the AI business as the results of the AI  business
were  previously  presented  on  a  discontinued  operations
basis.

NOTE  2  -  PRO  FORMA CONDENSED CONSOLIDATED  STATEMENT  OF
FINANCIAL POSITION

The  pro  forma adjustments are based upon current available
information and management's best estimates and are  subject
to  change.   The  pro forma adjustments  to  the  condensed
consolidated statement of financial position are  summarized
as follows:

  (a)  Cash  and  cash equivalents and notes receivable  were
       increased by $275 million and $150 million, respectively, to
       reflect the proceeds from the sale of the AI business to
       EG&G.  The notes receivable from EG&G bear interest at a
       rate of five percent per annum and have a one-year maturity.
       The proceeds are subject to adjustment based upon final
       determination of closing date net assets.
  (b)  Current  and  long-term  net assets  of  discontinued
       operations were reduced to zero to reflect the sale of the
       AI business.
  (c)  Other long-term assets was increased by $20.4 million
       to reflect the retention of certain property, plant and
       equipment that was not part of the sale transaction. These
       assets will be held available for sale.
  (d)  The  pro forma adjustments do not include transaction
       costs, other incremental costs and income taxes on the sale
       of the AI business, which are expected to approximate $60
       million to $75 million.  Transaction costs and  other
       incremental costs include investment banking,  legal,
       accounting,  severance, curtailment  of  pension  and
       postretirement benefits, and other direct costs.  Actual
       costs will be recorded as part of the gain on sale for the
       three month period ended June 30, 1999.  In addition, the
       purchase price is subject to adjustment based upon final
       determination of closing date net assets.  Therefore, the
       gain on the sale of AI included in shareholders' equity
       is subject to change upon finalization of such adjustments.

duration thereof or until such time as any Restricted Assets have been
transferred to Buyer pursuant to Section 2.5(d) or otherwise disposed of in
accordance with Section 2.5(e), use all reasonable efforts to (i) provide to
Buyer the benefits of any such Restricted Asset not assigned, transferred or
subleased due to Seller's or the PE Group's failure or inability to obtain

Buyer, or allow Buyer to enforce, any rights of the PE Group under any such
Restricted Asset against the issuer thereof or the other party or parties
thereto (including the right to elect to terminate such of the foregoing in
accordance with the terms thereof upon the request of Buyer); provided,
however, that the reasonable costs and expenses of the PE Group (including
reasonable professional fees and expenses) incurred at Buyer's request with
respect to any of the actions contemplated under (iii) above shall be
promptly paid or reimbursed by Buyer to Seller.  Upon the transfer or
disposition or termination of any Restricted Asset, the PE Group shall have
no further duties or obligations under this Section 2.5 with respect to such
Restricted Asset and the failure or inability to obtain any necessary consent
or waiver with respect thereto shall not be a breach of this Agreement so
long as the Asset Sellers have carried out their obligations under this
Section 2.5.  Prior thereto and subject to applicable law and regulations
(including, without limitation, all laws and regulations requiring investment
approvals or consents or anti-monopoly clearances, exemptions or waivers in
connection with any disposition of the Restricted Assets, and all exchange
controls and laws concerning foreign corrupt practices, expatriation of funds
or otherwise), the PE Group shall, in respect of any Restricted Assets, use
all reasonable efforts to follow and implement the reasonable written
instructions and policies of Buyer relating to the holding, management and
operation of the Restricted Assets.

          (c)  To the extent that Buyer is provided the benefits of any
Restricted Asset pursuant to clause (b) of this Section 2.5, Buyer shall
perform for the benefit of the issuer thereof, or the other party or parties
thereto, the obligations of any member of the PE Group thereunder or in
connection therewith, but only to the extent that (i) such action by Buyer
would not result in any default thereunder or in connection therewith and

                                     -13-

<PAGE>

(ii) such obligation would have been an Assumed Liability but for the non-
assignability or non-transferability thereof; provided, however, that if
Buyer shall fail to perform to the extent required herein, the PE Group shall
thereafter cease to be obligated under this Section 2.5 to provide Buyer with
any benefits in respect of the Restricted Asset which is the subject of such
failure to perform unless and until such situation is remedied or, at the
sole option of Seller, Buyer shall promptly pay or reimburse Seller to remedy
such failure to perform during such period of failure of performance.  For
purposes of this Section 2.5, the PE Group shall not include the Transferred
Subsidiaries after the Closing Date.  Subject to compliance by the PE Group
with any reasonable instructions and directions of Buyer, no member of the PE
Group shall have any liability to Buyer arising out of the management or
operation by the PE Group of any Restricted Assets other than for fraud,
gross negligence or willful misconduct.  Buyer shall reimburse the PE Group
and shall hold the PE Group harmless from and against all liabilities
actually incurred as a result of the post-Closing direct or indirect
ownership, management, operation or sale (other than to Buyer) of the
Restricted Assets by the PE Group, including, without limitation, the amount
of any additional Taxes payable by the PE Group (whether currently or in the
future) in excess of the amount of Taxes which would have been payable by the
PE Group, after application of the terms of this Agreement, if the Restricted
Assets had been transferred to Buyer on the Closing Date.  Subject to Buyer
receiving a request for payment from the PE Group (together with any related
bill, claim, invoice or other request for payment including such detail and
supporting documentation as Buyer shall reasonably request), such
reimbursement shall be made by Buyer not less than thirty (30) days prior to
the date on which the PE Group is required to make such payment (unless being
contested by Buyer in good faith, in which event the uncontested portion of
such reimbursement shall be paid by Buyer not less than thirty (30) days
prior to such date).  "Business Day" shall mean any day other than a Saturday
or Sunday or a day on which banking institutions located in New York, New
York are permitted or required by law, executive order or governmental decree
to remain closed.

          (d)  Unless otherwise disposed of upon Buyer's instructions in
accordance with Section 2.5(e), the consents, assignments and other good and
sufficient instruments of conveyance and assignment relating to the relevant
Restricted Assets as are necessary under applicable law in order to transfer
effectively such Restricted Assets, free and clear of all Encumbrances
(except Permitted Encumbrances and Encumbrances which are created with
Buyer's prior written consent during the period the Restricted Assets were
being held for Buyer's benefit), will be delivered to Buyer as soon as
practicable after all consents or waivers relating to any such Restricted
Assets or the transfer thereof shall have been obtained.

          (e)  At any time prior to the transfer to Buyer of any Restricted
Asset, the PE Group shall, on Buyer's written instructions (subject to

                                     -14-

<PAGE>

applicable law and regulations), or may at any time after three (3) years
from the Closing, with Buyer's consent (which shall not be unreasonably
withheld), for Buyer's benefit, dispose of the Restricted Assets and remit
the proceeds of such sale (less withholding or similar Taxes, if any, payable
with respect to such disposition or remittance) to Buyer; provided, that
Seller shall have no liability to any third party arising out of such
transactions other than for fraud, gross negligence or willful misconduct;
and provided, further, that any amount remitted to Buyer pursuant to this
Section 2.5(e) shall be reduced by, to the extent not previously paid by or
on behalf of Buyer pursuant to Section 2.5(c), the amount of any and all
liabilities described in Section 2.5(c) imposed upon or incurred by Seller as
a result of Seller's post-Closing direct or indirect ownership, management,
operation or sale of the Restricted Assets, including, without limitation,
the amount of any Taxes (other than Taxes previously paid by Buyer pursuant
to Section 2.5(c)) payable by Seller as a result thereof; and provided
further that any Contract, permit, license or other agreement or instrument
which is a Restricted Asset which has a fixed term of duration may not be
terminated or so disposed of by Seller prior to its expiration in accordance
with its terms except upon Buyer's specific instruction.

          (f)  For purposes of this Agreement, "Restricted Asset" means any
Asset (including any asset of an Asset Seller that was excluded from the
definition of Asset solely because it was not transferable but which may
become transferable after the Closing),  which Asset cannot be validly
assigned, transferred, subleased or sublicensed without the consent or waiver
of the issuer thereof or the other party or parties thereto or a third Person
(including a Governmental Authority), or with respect to which such
assignment, transfer, sublease or sublicense or attempted assignment,
transfer, sublease or sublicense could reasonably be expected to
(i) constitute a breach thereof or a violation of any law, decree, order,
regulation, rule, ordinance or other governmental edict, or (ii) entitle the
other party or parties thereto to terminate such Asset or receive any
additional payment thereunder; and "Restricted Assets" means all of them
collectively.  For purposes of this definition, "transfer" or similar word
shall include a transfer resulting or deemed to result under the terms of the
Restricted Asset as a consequence of the transfer of Subsidiary Stock and the
Assets to Buyer.

          (g)  With respect to those contracts, agreements or other
instruments which relate to both Assets or Assumed Liabilities and Excluded
Assets or Excluded Liabilities (the "Shared Contracts"), the Transition
Agreements shall provide for Buyer to receive the benefits and assume the
liabilities of the Shared Contracts to the extent such rights and liabilities
under the Shared Contracts relate to Assets and Assumed Liabilities and for
Seller to retain the benefits and liabilities of the Shared Contracts to the
extent such rights and liabilities under Shared Contracts relate to Excluded
Assets and Excluded Liabilities.

          2.6. Post-Closing Adjustments.   (a)  Within 60 days following the
Closing, Seller shall, at its expense, prepare, or cause to be prepared, and
deliver to Buyer an audited Combined Statement of Net Assets to Be Sold of
the Analytical Instruments Business together with the notes thereto and the
report thereon of PricewaterhouseCoopers, LLP (the "Closing Balance Sheet")
which shall set forth the Net Assets of the Analytical Instruments Business
immediately prior to the Closing (the "Closing Net Assets").  The Closing
Balance Sheet shall be prepared, and Closing Net Assets calculated, using the
same accounting principles, methods, practices, allocation methodologies and
estimation methodologies as were utilized in the preparation of the 1998
Statement of Net Assets after giving effect to the adjustments set forth in
Section 3.1(g) of the Seller Schedule.  For purposes hereof, "Net Assets"
means the excess of the total assets of the Analytical Instruments Business
to be sold over the total liabilities of the Analytical Instruments Business
to be assumed as reflected in a combined statement of net assets of the
Analytical Instruments Business prepared and calculated as provided in the
immediately preceding sentence.  At the same time, Seller shall deliver a
statement  (the "Subsidiary Statement") indicating the excess (the
"Preliminary Adjustment Amount") of:  (i) the amount (on a combined basis) as
of the Closing Date of the cash and cash equivalents of the Transferred
Subsidiaries (the "Subsidiary Cash Amount"); over  (ii) the amount (on a
combined basis) as of the Closing Date of the Indebtedness of the Transferred
Subsidiaries to parties other than Seller or any of its subsidiaries (other
than the Transferred Subsidiaries) (the "Subsidiary Debt Amount").  The
Subsidiary Statement shall be prepared and determined in accordance with U.S.
GAAP.

          (b)  Buyer and Buyer's accountants shall, within 60 days after the
delivery by Seller of the Closing Balance Sheet and Subsidiary Statement and
calculation of Closing Net Assets and the Preliminary Adjustment Amount,
complete their review of Closing Net Assets and the Preliminary Adjustment
Amount.  In the event that Buyer determines that Closing Net Assets or the
Preliminary Adjustment Amount have not been determined in accordance with the
accounting principles, methods, practices and estimation methodologies
required pursuant to Section 2.6(a), Buyer shall inform Seller in writing
(the "Buyer's Objection"), setting forth a specific description of the basis
of Buyer's Objection and the adjustments to Closing Net Assets and the
Preliminary Adjustment Amount which Buyer believes should be made, on or
before the last day of such 60-day period.  Seller shall then have 30 days to
review and respond to Buyer's Objection.  If Seller and Buyer are unable to
resolve all of their disagreements with respect to the determination of the
foregoing items within 30 days following the completion of Seller's review of
Buyer's Objection, they shall refer their remaining differences to KPMG Peat
Marwick or another nationally recognized firm of independent public
accountants as to which Seller and Buyer mutually agree (the "Accounting
Firm") who shall, acting as experts in accounting and not as arbitrators,
determine on the basis of the standards set forth in Section 2.6(a), and only

                                     -16-

<PAGE>

with respect to the specific remaining accounting related differences so
submitted, whether and to what extent, if any, Closing Net Assets or the
Preliminary Adjustment Amount requires adjustment.  Seller and Buyer shall
direct the Accounting Firm to use its best efforts to render its
determination within 45 days.  The Accounting Firm's determination shall be
conclusive and binding upon Buyer and Seller.  The fees and disbursements of
the Accounting Firm shall be shared equally by Buyer, on the one hand, and
Seller, on the other hand.  Buyer and Seller shall make readily available to
the Accounting Firm all relevant books and records and any work papers
(including those of the parties' respective accountants) relating to the 1998
Statement of Net Assets, the January 1999 Financial Statements, the Closing
Balance Sheet, the Closing Net Assets, the Preliminary Adjustment Amount and
all other items reasonably requested by the Accounting Firm.  The "Adjusted
Closing Net Assets" shall be (i) the Closing Net Assets in the event that
(x) no Buyer's Objection is delivered to Seller during the 60-day period
specified above, or (y) Seller and Buyer so agree, (ii) the Closing Net
Assets, adjusted in accordance with Buyer's Objection in the event that
Seller does not respond to Buyer's Objection within the 30-day period
following receipt by Seller of Buyer's Objection, or (iii) the Closing Net
Assets, as adjusted by either (x) the agreement of Seller and Buyer or
(y) the Accounting Firm.  The "Final Adjustment Amount" shall be (A) the
Preliminary Adjustment Amount in the event that (x) no Buyer's Objection is
delivered to Seller during the 60-day period specified above, or (y) Seller
and Buyer so agree, (B) the Preliminary Adjustment Amount, adjusted in
accordance with Buyer's Objection in the event that Seller does not respond
to Buyer's Objection within the 30-day period following receipt by Seller of
Buyer's Objection or (C) the excess of the Subsidiary Cash Amount over the
Subsidiary Debt Amount as determined by either the agreement of Seller and
Buyer or the Accounting Firm.

          (c)  Buyer shall provide Seller and its accountants full access to
the books and records of the Analytical Instruments Business, to any other
information, including work papers of their accountants, and to any employees
to the extent necessary for Seller to prepare the Closing Balance Sheet or
the Subsidiary Statement and determine Closing Net Assets and the Preliminary
Adjustment Amount.  Buyer and its accountants shall have prior notice of and
the opportunity to observe the taking of the Inventory (which may begin prior
to the Closing Date) in connection with the preparation of the Closing
Balance Sheet, Closing Net Assets and the Subsidiary Statement and shall have
full access to all information used by Seller in preparing the Closing
Balance Sheet and Closing Net Assets, the 1999 Financial Statements and the
Subsidiary Statement, including the procedures, books, records and (subject
to customary undertakings) work papers of its accountants.  Seller shall
provide Buyer and Buyer's accountants full access to the books and records of
Seller, including work papers of its accountants (subject to customary
undertakings) and to any employees in connection with the 1998 Financial


                                     -17-

<PAGE>

Statements and the Subsidiary Statement and the accounting principles,
methods, practices and allocation methodologies.

          (d)  Within 10 business days following determination of the
Adjusted Closing Net Assets, Buyer or Seller, as the case may be, shall make
an adjustment payment in U.S. dollars in the applicable amount hereinafter
provided.  The adjustment payment will be made by Seller to Buyer to the
extent that the Adjusted Closing Net Assets are less than $132 million and by
Buyer to Seller to the extent that Adjusted Closing Assets are greater than
$142 million, plus, in either case, interest thereon from the Closing Date
through the date of payment at a rate equal to the 30-day commercial paper
rate for high-grade unsecured notes sold through dealers by major
corporations as listed in the Money Rates table of The Wall Street Journal on
the Closing Date (the "Interest Rate").  In addition, in the event that the
Final Adjustment Amount is positive, Buyer shall make a payment to Seller in
U.S. dollars in an amount equal to the Final Adjustment Amount within
ten (10) days following its determination.  In the event that the Final
Adjustment Amount is negative, Seller shall make a payment to Buyer in U.S.
dollars in an amount equal to the Final Adjustment Amount within ten (10)
days following its final determination. The Final Adjustment Amount shall be
paid with interest at the rate provided above for the period from the Closing
Date through the date of payment.  The adjustment payments payable pursuant
to the foregoing provisions of this Section 2.6(d) shall be paid by wire
transfer of immediately available funds to an account designated by Buyer, on
the one hand, or Seller, on the other hand, as the case may be.

          (e)       With respect to that certain Profit & Loss Pooling
Agreement between Perkin-Elmer Holding GmbH Ueberlingen ("PEH") and
Bodenseewerk Perkin-Elmer GmbH ("BSW"), Buyer shall promptly reimburse Seller
for any payment made by PEH to BSW and Seller shall promptly reimburse Buyer
for any payment made by BSW to PEH pursuant to that agreement if such
payments are made after the Closing Date due to the requirements of German
law and the statutory audit.  Any such reimbursement by Buyer or Seller shall
be considered an adjustment to the Purchase Price.  Seller shall cause PEH to
promptly reimburse BSW, or Buyer shall cause BSW to reimburse PEH, as the
case may be, for any amount due to or from either BSW or PEH with respect to
the VAT account between PEH and BSW promptly after the determination thereof
and in any case prior to the time for payment thereof.

3.   Representations and Warranties

          3.1. Representations and Warranties of Seller.  Except as set forth
in the Seller Schedule, Seller, on behalf of itself and the Subsidiaries,
including, without limitation, the Transferred Subsidiaries and the Asset
Sellers, represents and warrants to Buyer that the statements contained in
this Section 3.1 are true, complete and correct.  As used in this Agreement,

operations, results of operations, financial condition, assets or business of
the Analytical Instruments Business taken as a whole, and a "Seller
Representation Adverse Effect" means any adverse effect on the operations,
results of operations, financial condition, assets or business of the
Analytical Instruments Business that is reasonably expected to result in a
liability to the Analytical Instruments Business in excess of $500,000.

          (a)  Due Organization; Good Standing and Power.  Section 3.1(a) of
the Seller Schedule sets forth a true, complete and correct list of all the

such number owned beneficially and of record by Seller or the Subsidiaries.
Seller and each of the Subsidiaries is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation and has the requisite corporate power and authority to own,
lease and operate its property and to conduct the Analytical Instruments
Business as currently conducted by it.  Seller has all requisite corporate
power and authority to enter into this Agreement and each of the other
agreements contemplated hereby to be entered into by it and to perform its

title to Buyer with respect to the Subsidiary Stock owned by it.  Each of
Seller and the Subsidiaries is duly authorized, qualified or licensed to do
business as a foreign corporation and is in good standing in each of the
jurisdictions in which its right, title or interest in or to any of the
Assets held by it, or the conduct of the Analytical Instruments Business by
it, requires such authorization, qualification or licensing, except where the
failure to so qualify or to be in good standing would not, individually or in
the aggregate, have a Seller Representation Adverse Effect or materially
impair either (i) the ability of Seller or such Subsidiary to perform its
obligations hereunder or under any other agreement contemplated hereby to
which it is a party or (ii) the ability of Buyer to own the Assets and
Subsidiary Stock, and operate the Analytical Instruments Business, after the
Closing (except as may be affected by considerations applicable to Buyer that
would not be applicable to any other third party purchaser of the Analytical
Instruments Business).

          (b)  Authorization and Validity of Agreement.  The execution,
delivery and performance by Seller of this Agreement and by each of Seller

                                     -19-

<PAGE>

and each Subsidiary of any other agreements contemplated hereby (to the
extent such entity is a party thereto) and the consummation by each of the
transactions contemplated hereby and thereby have been duly authorized by the
Board of Directors of Seller.  No other corporate or stockholder action is
necessary for the authorization, execution, delivery and performance by
Seller of this Agreement and by each of Seller and each Subsidiary of any
other agreements contemplated hereby  (to the extent such entity is a party
thereto) and the consummation by Seller and the Subsidiaries of the
transactions contemplated hereby or thereby, other than certain corporate

delivered by Seller and constitutes a valid and legally binding obligation of
Seller, enforceable against it in accordance with its terms, subject to
(i) the effects of bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting
the enforcement of creditors' rights generally, (ii) general equitable
principles (whether considered in a proceeding in equity or at law) and
(iii) an implied covenant of good faith and fair dealing.  When executed and
delivered as provided in this Agreement, each other agreement contemplated
hereby to be executed and delivered by Seller or any Subsidiary will be a
valid and legally binding obligation of Seller or such Subsidiary (to the
extent a party thereto), enforceable against Seller or such Subsidiary in
accordance with its terms, subject to (i)  the effects of bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium and other
similar laws relating to or affecting the enforcement of creditors' rights
generally, (ii) general equitable principles (whether considered in a
proceeding in equity or at law) and (iii) an implied covenant of good faith
and fair dealing.

          (c)  No Governmental Approvals or Notices Required; No Conflict
with Instruments to Which Company Is a Party.  Except for the pre-merger
notification requirements of the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, as amended, and the rules and regulations thereunder (the "HSR Act")
or as set forth in Section  3.1(c) of the Seller Schedule, the execution,
delivery and performance of this Agreement and any other agreements
contemplated hereby by Seller and the Subsidiaries and the consummation by
them of the transactions contemplated hereby and thereby (i) will not violate
(with or without the giving of notice or the lapse of time or both), or
require any consent, approval, filing or notice to be made by Seller or any
Subsidiary under, any provision of any law, rule or regulation, court order,
judgment or decree or Material Permit (to the extent transferable) applicable
to Seller or any Subsidiary, except for such violations the occurrence of
which, and such consents, approvals, filings or notices the failure of which
to obtain or make, would not, individually or in the aggregate, have a Seller
Representation Adverse Effect, or materially impair either (A) the ability of
Seller and the Subsidiaries to perform their respective obligations under
this Agreement and the other agreements contemplated hereby or (B) except as

                                     -20-

<PAGE>

may be affected by considerations applicable to Buyer that would not be
applicable to any other third party purchaser of the Analytical Instruments
Business, the ability of Buyer to own the Assets and Subsidiary Stock, and
operate the Analytical Instruments Business after the Closing in the same
manner as conducted by the Company before the Closing (except as may be
affected by considerations applicable to Buyer that would not be applicable
to any other third party purchaser of the Analytical Investments Business)
and (ii) will not conflict with, or result in the breach or termination of
any provision of, require the counterparty's consent under or constitute a
default under, or result in the acceleration of the performance of the
obligations of Seller or any Subsidiary under, or result in the creation of a
lien, charge or encumbrance upon a portion of the properties or assets of any
Seller or any Subsidiary included in the Assets or the Analytical Instruments
Business pursuant to, the charter or by-laws (or analogous organizational
documents) of Seller or any Subsidiary, or any indenture, mortgage, deed of
trust, lease, licensing agreement, contract, instrument or other agreement to
which Seller or any such Subsidiary is a party or by which Seller or any
Subsidiary or any of the Assets held by Seller or any Subsidiary is bound,
except for such conflicts, breaches, consents, terminations, defaults,
accelerations, liens, charges or encumbrances which would not, individually
or in the aggregate, have a Seller Representation Adverse Effect or
materially impair the ability of Seller or such Subsidiary to perform its
obligations under this Agreement or any other agreement contemplated hereby
to which it is a party (except as may be affected by considerations
applicable to Buyer that would not be applicable to any other third party
purchaser of the Analytical Instruments Business).

          (d)  Capital Stock of the Transferred Subsidiaries.  (i) There are
no options, warrants, convertible securities or other rights, subscriptions,
agreements, arrangements or commitments relating to the capital stock of, or
equity interests in, any of the Transferred Subsidiaries obligating Seller or
any of the Subsidiaries to issue, sell or acquire any shares of capital stock
of, or equity interests in, any Transferred Subsidiary or entitling any third
party to acquire from any Transferred Subsidiary any shares of capital stock
or other securities of such Transferred Subsidiary.

          (ii) The Subsidiary Stock constitutes all of the issued and
     outstanding shares of capital stock of each Transferred Subsidiary and
     good title to the Subsidiary Stock is owned of record and beneficially
     solely by Seller or a wholly owned subsidiary of Seller, free and clear
     of all Encumbrances, other than certain nominee shares (the "Nominee
     Shares"), as to which Seller and its subsidiaries have the requisite
     contractual authority to convey good title to Buyer as set forth in
     Section  3.1(d) of the Seller Schedule.  All of the shares of Subsidiary
     Stock have been duly authorized and validly issued and are fully paid
     and nonassessable and were not issued in violation of and are free of
     any preemptive rights.  There are no voting trusts, stockholder

                                     -21-

<PAGE>

     agreements, proxies or other agreements or understandings in effect with
     respect to the voting or transfer of any of the shares of Subsidiary
     Stock except with respect to the Nominee Shares as described in
     Section 3.1(d) of the Seller Schedule.

          (iii)  Subject only to recording on the books of the respective
     Transferred Subsidiaries, the transfer of the shares of Subsidiary Stock
     to Buyer at Closing will vest in Buyer good title to such shares, free
     and clear of all Encumbrances, except for any Encumbrances resulting
     from any action taken or omitted to be taken by or on behalf of Buyer.

          (iv)  No Transferred Subsidiary holds any direct or indirect equity
     interest in any other partnership, firm, corporation, limited liability
     company, association, trust, unincorporated organization or entity, or
     any syndicate or group that would be deemed to be a Person under
     Section 13(d)(3) of the United States Securities Exchange Act of 1934,
     as amended ("Person"), except for another Transferred Subsidiary.

          (e)  Entire Business.  Upon consummation of the transactions
contemplated by this Agreement, Buyer will acquire, or will acquire the
legally enforceable right to use, all the properties and assets included in
the Assets, and the properties and assets of the Transferred Subsidiaries and
such properties, assets and the rights acquired by Buyer, together with the
services to be provided to, and other rights of, Buyer under the Buyer
License Agreement and the Transition Agreements, shall be sufficient for
Buyer to conduct the Analytical Instruments Business in the same manner as it
is currently conducted, except, in each case, as may be affected by
circumstances applicable to Buyer that would not be applicable to any third
party purchaser of the Analytical Instruments Business.

          (f)  Title to Properties.  The Asset Sellers and Transferred
Subsidiaries are, and immediately prior to the Closing will be, the true and
lawful owner of the Assets and the assets and properties of the Transferred
Subsidiaries, and will have the right to, and at the Closing shall, sell and
transfer to Buyer at Closing good, record and marketable title to the Assets,
free and clear of all liens, pledges, charges, encumbrances and equities of
any kind affecting either the Assets or the assets and properties of the

forth in Section 3.1(f) of the Seller Schedule; (B) as disclosed in the
Financial Information; (C) liens for Taxes, assessments and other
governmental charges not yet due and payable but not delinquent, or being
contested in good faith by appropriate proceedings; (D) mechanics',
workmen's, repairmen's, warehousemen's, carriers' or other like liens arising
or incurred in the Ordinary Course of Business, original purchase price
conditional sales contracts and equipment leases with third parties entered
into in the Ordinary Course of Business which, individually or in the
aggregate, would not materially adversely affect the use or value of such

                                     -22-

<PAGE>

assets or properties; (E) with respect to real property, (1) easements,
quasi-easements, licenses, covenants, rights-of-way and other similar
restrictions, including, without limitation, any other agreements, conditions
or restrictions which would be shown by a current title report or other
similar report or listing, (2) any conditions that may be shown by a current
survey, title report or physical inspection and (3) zoning, building and
other similar restrictions which in the case of (1), (2) and (3)
individually or in the aggregate, would not materially adversely affect the
use or value of such assets or properties; and (F) liens, charges or other
encumbrances which, individually or in the aggregate, would not materially
adversely affect the use or value of such assets or properties (collectively,
"Permitted Encumbrances") or Encumbrances resulting from any action taken or
omitted to be taken by or on behalf of Buyer.

("Governmental Authority") pending or, to the knowledge of the Company,
contemplated or threatened against the Company or the Analytical Instruments
Business, that would reasonably be expected to have, individually or in the

Foreign Corrupt Practices Act and the U.S. Occupational Safety and Health Act
and regulations thereunder) except in such cases where non-compliance, either
individually or in the aggregate, would not result in a Seller Representation
Adverse Effect, and neither Seller nor any Subsidiary has received any
written notice to the effect that the Analytical Instruments Business is not
in compliance with any applicable law or order of any Governmental Authority
where non-compliance, either individually or in the aggregate, would result

applicable laws relating to the Analytical Instruments Business, the Assets
or the Transferred Subsidiaries except in such cases where the failure to so
file would not, either individually or in the aggregate, be expected to

          (ii) No Transferred Subsidiary nor,  in connection with the
     Analytical Instruments Business, any Asset Seller is, or since January

     subcontracts with any Governmental Authority; no such suspension or
     debarment has been initiated or, to the knowledge of the Company,
     threatened in writing; and the consummation of the transactions
     contemplated by this Agreement will not result in any such suspension or
     debarment (assuming that no such suspension or debarment will result
     from the identity of Buyer).  Except as set forth in Section 3.1(k) of
     the Seller Schedule, no Transferred Subsidiary or,  in connection with
     the Analytical Instruments Business, Asset Seller has, since January 1,
     1996, been audited or (to the knowledge of the Company) investigated or

     Accounting Office, the U.S. Department of Defense or any of its
     agencies, the Defense Contract Audit Agency, the U.S. Department of
     Justice, the Inspector General of any U.S. Governmental Authority, any
     similar agencies or instrumentalities of any foreign Governmental
     Authority, or any prime contractor with a Governmental Authority except
     as would not be expected to result in a Seller Representation Adverse
     Effect.  To the knowledge of the Company, there is no valid basis for
     (A) the suspension or debarment of any Transferred Subsidiary or,  in
     connection with the Analytical Instruments Business, Asset Seller, from
     bidding on contracts or subcontracts with any Governmental Authority or
     (B) any claim pursuant to any audit by any Governmental Authority in
     connection with any contracts or subcontracts relating to the provision
     of products or services to or for the benefit of a Governmental
     Authority except as would not reasonably be expected to have a Seller
     Representation Adverse Effect.  No Transferred Subsidiary or,  in
     connection with the Analytical Instruments Business, Asset Seller, has
     any agreements, contracts or commitments which require it to obtain or
     maintain a security clearance with any Governmental Authority.

the conduct of the Analytical Instruments Business, Asset Seller, has, since
January 1, 1996, experienced nor, to the knowledge of the Company, is there
currently threatened, any (A) work stoppages or strikes, (B) grievance,
arbitration proceedings or proceedings before any industrial tribunal arising
out of collective bargaining agreements, national labor union agreements or
otherwise covering employees of the Analytical Instruments Business, or
(C) unfair labor practice complaints, which would have a Seller
Representation Adverse Effect.  To the knowledge of the Company, there is no
organizational effort presently being made or threatened by or on behalf of
any labor union or any formal collective bargaining agreement being

Business.

     complete and correct list of each collective bargaining agreement or

<PAGE>

     other labor union contract applicable to persons employed in the
     Analytical Instruments Business other than statutory arrangements under
     applicable foreign laws and no other collective bargaining agreement is
     being negotiated by the Company.  Except as set forth in Section 3.1(l)
     of the Seller Schedule, no Asset Seller or Transferred Subsidiary
     recognizes (expressly or impliedly) any trade union.

          (m)  Inventories; Receivables.   (i)  The inventories of the
Analytical Instruments Business are reflected in the Financial Statements at
the lower of cost (determined on the first-in first-out method) or market, in
conformity with U.S. GAAP.

          (ii)      All accounts receivable of the Analytical Instruments
     Business reflected in the Financial Statements have arisen from bona
     fide transactions in accordance with the requirements with U.S. GAAP and

     with the requirements of U.S. GAAP.

          (n)  Intellectual Property.  (i)  The Intellectual Property set

together with the Intellectual Property set forth, summarized and/or
described in Section 4.8(a) of the Seller Schedule (to be licensed to Buyer
pursuant to the Buyer License Agreement), constitute all the Intellectual
Property necessary to conduct the Analytical Instruments Business as
currently conducted.  In the event any Intellectual Property is erroneously
included in, or omitted from, these schedules, the parties agree to correct
such schedules prior to the Closing, so that the final schedules reflect the
parties' true intent regarding the proper allocation of Intellectual Property
between them.

          (ii)      Upon execution and delivery by the Asset Sellers to Buyer
     of the instruments of conveyance referred to in Section 1.4 and the
     Buyer License Agreement, and subject to Section 2.5, each item of
     Intellectual Property owned or used by the Asset Sellers and the
     Transferred Subsidiaries and necessary to conduct the Analytical
     Instruments Business as currently conducted as of the Closing will be
     owned or available for use by Buyer or the Transferred Subsidiaries on
     substantively identical terms and conditions immediately following the
     Closing.  Each of the Asset Sellers and the Transferred Subsidiaries has
     taken reasonable measures to protect the proprietary nature of such
     Intellectual Property and to maintain in confidence the trade secrets,
     know-how and confidential information that it owns or uses and is
     necessary to conduct the Analytical Instruments Business as currently
     conducted.  No other Person has any rights to any of the material
     Intellectual Property owned or used by the Asset Sellers or the
     Transferred Subsidiaries that is necessary to conduct the Analytical
     Instruments Business as currently conducted, except that the

                                     -28-

<PAGE>

     Intellectual Property identified in Section 1.2(a) of the Seller
     Schedule is owned by the respective owners identified therein.  To the
     knowledge of the Company, no Person is infringing, violating or
     misappropriating any of the material Intellectual Property to be
     conveyed to Buyer at Closing.

          (iii)     To the Company's knowledge and except as set forth in
     Section 3.1(n)(iii) of the Seller Schedule, none of the activities of
     the Analytical Instruments Business as currently conducted materially
     infringes or violates, or constitutes a material misappropriation of,
     any Intellectual Property of any other Person (including, without
     limitation, Seller or any Subsidiary).  Except as disclosed in Section
     3.1(n)(iii) of the Seller Schedule, no Transferred Subsidiary or Asset
     Seller has received since January 1, 1996, any complaint, claim or
     notice in writing alleging any such infringement, violation or
     misappropriation with respect to any Intellectual Property to be
     conveyed or licensed to Buyer pursuant to this Agreement or the Buyer
     License Agreement, which complaint, claim or notice has not been
     resolved to the mutual satisfaction of the parties involved in a manner
     which involves no future obligations of Seller or any Subsidiary, except
     to the extent any of the foregoing would not reasonably be expected to
     result in a Seller Representation Adverse Effect.

          (iv)      Except as disclosed in Section 3.1(n)(iv) of the Seller
     Schedule, with respect to each item of Intellectual Property necessary
     to conduct the Analytical Instruments Business as currently conducted
     and owned by a third party and used by a Transferred Subsidiary or, in
     the conduct of the Analytical Instruments Business, an Asset Seller:

               (A)  the license, sublicense or other agreement covering such
     item is, to the Company's knowledge, legal, valid, binding, enforceable
     and in full force and effect with respect to the Asset Seller or
     Transferred Subsidiary which is a party thereto;

               (B)  such license, sublicense or other agreement to which an
     Asset Seller is a party is assignable by the Asset Seller to Buyer
     without the consent or approval of or any payment to any party;

               (C)  the consummation of the transactions contemplated herein
     will not conflict with, result in a violation or breach of or constitute
     a default under (or would result in a violation, breach or default with
     the giving of notice or the passage of time or both) any such license,
     sublicense or other agreement which violation, breach or default
     (together with all other such violations, breaches or defaults) would
     have a Seller Representation Adverse Effect;



                                     -29-

<PAGE>

               (D)  no Asset Seller, Transferred Subsidiary or, to the
     Company's knowledge, any other party is in material breach or default
     under any such license, sublicense or other agreement, and to the
     Company's knowledge, no event has occurred which, with notice or the
     passage of time or both, would constitute such a breach or default or
     permit a termination, modification or acceleration thereunder;

               (E)  the underlying item of Intellectual Property is not
     subject to any outstanding order of any Governmental Authority; and

               (F)  no Asset Seller or Transferred Subsidiary has agreed,
     except in the Ordinary Course of Business in conjunction with product
     sales, to indemnify any Person or entity for or against any
     interference, infringement, misappropriation or other conflict with
     respect to such item.

          (o)  Government Licenses, Permits and Related Approvals.
(i) Except as described in Section 3.1(o) of the Seller Schedule, the Asset

licenses, permits and authorizations, including, without limitation, all
permits required under Environmental Laws necessary for the current use,
occupancy and operation of the Analytical Instruments Business (the "Material
Permits"), (B) are in compliance in all material respects with all such
Material Permits and (C) have made all required filings with, or
notifications to, all Governmental Authorities pursuant to applicable
requirements of all laws applicable to the Analytical Instruments Business
except for such failures to hold, be in compliance with or make filings or
notifications that individually or in the aggregate would not have a Seller
Representation Adverse Effect.

          (ii)      Each Material Permit is in full force and effect and no
     suspension or cancellation of any Material Permit has been, to the
     knowledge of the Company, threatened in writing except for such
     suspensions or cancellations as would not have a Seller Representation
     Adverse Effect.  Except as described in Section 3.1(o) of the Seller
     Schedule, and except in each case for any Material Permits listed in
     Section 1.2(h) of the Seller Schedule , all such Material Permits
     (whether held by an Asset Seller or Transferred Subsidiary) will
     continue to be in full force and effect immediately following the
     Closing for the benefit of Buyer in accordance with the terms thereof as
     in effect immediately prior to the Closing, except to the extent that
     the failure to be in full force or effect will not have a Seller
     Representation Adverse Effect. To the knowledge of the Company, there is
     no proposed or contemplated change in the terms of any Material Permit
     which would, individually or in the aggregate, have a Seller
     Representation Adverse Effect.

          (p)  Employee Benefit Plans.  (i)  Section 3.1(p) of the Seller
Schedule sets forth a true, complete and correct list of each "employee
benefit plan" (as defined in Section 3(3) of the Employee Retirement Income
Security Act ("ERISA")) and all other employee benefit, bonus, incentive,
deferred compensation, stock purchase, stock option, severance, change in
control and fringe benefit plans (other than any employment or personnel
policy, practice or procedure) (hereinafter, "Benefit Plans") maintained or
contributed to by Seller, any Transferred Subsidiary or any ERISA Affiliate
for current or former employees (other than Foreign Employees) of the
Analytical Instruments Business (collectively, the "Seller Benefit Plans").
For purposes of this Agreement, "ERISA Affiliate" is any entity which is or
was at any relevant time, (A) a member of a controlled group of corporations
(as defined in Section 414(b) of the Code), or (B) a group of trades or
businesses under common control (as defined in Section 414(c) of the Code).
Section 3.1(p) of the Seller Schedule separately identifies those Seller
Benefit Plans that are maintained exclusively for the benefit of employees of
one or more Transferred Subsidiaries.  With respect to each Seller Benefit
Plan, Seller has made available to Buyer a true, complete and correct copy of
the following, if any: (1) the most recent summary plan description for each
Seller Benefit Plan for which a summary plan description is required,
(2) such Seller Benefit Plan, and each trust agreement relating to such
Seller Benefit Plan, (3) in the case of each Seller Benefit Plan applicable
to United States Employees, the most recent annual reports (Form 5500) filed
with the Internal Revenue Service ("IRS"), (4) the most recent determination
letter issued by the IRS with respect to any Seller Benefit Plan intended to
be qualified under Section 401(a) of the Code, (5) the most recent financial
statement for each Seller Benefit Plan, and (6) the most recent actuarial
statement for each Seller Benefit Plan that is a defined benefit plan.

          (ii)      With respect to any Benefit Plans maintained by the
     Seller, any Transferred Subsidiary or an ERISA Affiliate, no event has
     occurred and there exists no condition or set of circumstances in
     connection with which the Company could be subject to any fine, penalty,
     tax or any other liability under the terms of such Benefit Plans, ERISA,
     the Code, or any other applicable law which would, individually or in
     the aggregate, have a Seller Representation Adverse Effect.

          (iii)     Except as set forth in Section 3.1(p) of the Seller
     Disclosure Schedule, there are no inquiries or investigations by the
     IRS, the U.S. Department of Labor, or the Pension Benefit Guaranty
     Corporation, no termination proceedings and no actions, suits or claims
     (other than claims for benefits in the Ordinary Course of Business)
     pending or, to the knowledge of the Company, threatened against any
     Seller Benefit Plan (or any Transferred Subsidiary with respect thereto)
     or the assets thereof which would have a Seller Representation Adverse
     Effect.


                                     -31-

          (iv)      The Company is in full compliance with the terms of each
     of the Seller Benefit Plans and all applicable laws relating to the
     Seller Benefit Plans, including, without limitation, ERISA, the Code and
     the Health Insurance Portability and Accountability Act of 1996, all
     required filings have been made and all required contributions have been
     made to the Seller Benefit Plans, except where a failure to comply, file
     or contribute, would result in a Seller Representation Adverse Effect.

          (v)       Neither Seller, any ERISA Affiliate nor any Transferred
     Subsidiary has any liability which remains unsatisfied to a
     "multiemployer plan" as defined in Section 4001(a)(3) of ERISA (a
     "Multiemployer Plan"), in an amount which would have a Seller
     Representation Adverse Effect.  None of the Seller Benefit Plans is a
     Multiemployer Plan and no Seller, ERISA Affiliate nor Transferred
     Subsidiary has been required to contribute to, or sponsor, any
     Multiemployer Plan after 1980.

          (vi)      The Seller Benefit Plans that are intended to be
     qualified under Section 401(a) of the Code have received determination
     letters from the Internal Revenue Service to the effect that such Seller
     Benefit Plans are qualified and the plans and the trusts related thereto
     are exempt from federal income taxes under Sections 401(a) and 501(a),
     respectively, of the Code and, to the knowledge of Seller, it has
     received no notice of an act or omission which has occurred since the
     date of the last favorable determination letter issued with respect to a
     Seller Benefit Plan which would reasonably be expected to result in the
     revocation of such Benefit Plan's qualified status.

          (vii)     Other than as disclosed in Section 3.1(p) of the Seller
     Schedule, no agreement or obligation exists to increase benefits or to
     materially increase the employer cost of providing benefits under any
     Seller Benefit Plan, in each case to a level above that in effect as of
     the date of this Agreement, or to adopt any new Seller Benefit Plan,
     where the increased liability in the aggregate would have a Seller
     Representation Adverse Effect.

          (viii)    Except as set forth in Section 3.1(p) of the Seller
     Schedule, there is no (A) agreement, plan or arrangement under which any
     Person may receive payments from Seller or any Subsidiary with respect
     to the Analytical Instruments Business, that may be subject to the tax
     imposed by Section 4999 of the Code or included in the determination of
     such Person's "parachute payment" under Section 280G of the Code; and
     (B) agreement or plan binding on any Transferred Subsidiary, any of the
     benefits of which will be increased, or the vesting of the benefits of
     which will be accelerated, by the occurrence of any of the transactions
     contemplated by this Agreement or the value of any of the benefits of
     which will be calculated on the basis of any of the transactions

                                     -32-

<PAGE>

     contemplated by this Agreement, which in the aggregate would result in

     Nonetheless, there is no assurance that any non-compliant systems of
     such parties will become Year 2000 Compliant in a timely manner, and it
     is recognized that failure to do so could have a Seller Material Adverse
     Effect.

          (iv) For purposes of this Agreement, "Year 2000 Compliant" shall
     mean, with respect to a particular system or item, that:

               (A)  No value for current date will cause any interruption in
     operation, but only through the year 2018;

               (B)  Date-based functionality must behave consistently, and

     to, during, and after the year 2000 but only through the year 2018;

               (C)  In all interfaces and data storage, the century in any
     date from the present through the year 2018 must be specified either
     explicitly or by unambiguous algorithms or inferencing rules; and

               (D)  Year 2000 must be recognized as a leap year;

provided in each case, that all applications, hardware and other systems used
in conjunction therewith correctly exchange date data with, or provide data
to such system or item and are otherwise Year 2000 Compliant.

          (v)  With respect to any appropriate remediation to the Internal
     Systems or External Software that is required to make them Year 2000

     create a material disruption to the Analytical Instruments Business or
     cause a material defect in the products currently manufactured by or the
     services currently sold by, or under a warranty that covers Year 2000
     Compliance from, the Analytical Instruments Business, and the testing of
     the foregoing, as so remediated, (i) a substantial amount of the
     foregoing is reasonably expected to be completed by September 1, 1999
     and (ii) all of the foregoing is reasonably expected to be completed by
     December 31, 1999, provided that Buyer continues to support the Year

Buyer to perform its obligations hereunder or under any other agreement
contemplated hereby.

delivery and performance by Buyer of this Agreement and any other agreements
contemplated hereby, the delivery and issuance of the Note and the

          (c)  No Governmental Approvals or Notices Required; No Conflict
with Instruments to Which Buyer Is a Party.  The execution, delivery and
performance of this Agreement and any other agreements contemplated hereby by
Buyer, the issuance of the Note and the consummation by Buyer of the
transactions contemplated hereby and thereby (i) will not violate (with or
without the giving of notice or the lapse of time or both), or require any
consent, approval, filing or notice under, any provision of any law, rule or
regulation, court order, judgment or decree applicable to Buyer, except for
such violations the occurrence of which, and such consents, approvals,
filings or notices the failure of which to obtain or make, would not
materially impair the ability of Buyer to perform its obligations under this
Agreement and the other agreements contemplated hereby and (ii) will not
conflict with, or result in the breach or termination of any provision of, or
constitute a default under, or result in the acceleration of the performance
of the obligations of Buyer under, the charter or by-laws of Buyer or any
indenture, mortgage, deed of trust, lease, licensing agreement, contract,
instrument or other agreement to which Buyer is a party or by which Buyer or
any of its assets or properties is bound, except for such conflicts,
breaches, terminations, defaults, accelerations, liens, charges or

          (e)  Legal Proceedings.  There is no litigation, proceeding, tax
audit or governmental investigation pending or, to the knowledge of Buyer,
threatened in writing which seeks to question, delay or prevent the
consummation of, or would materially impair the ability of Buyer to
consummate the transactions contemplated hereby.

officers, directors or employees or any investment banker, financial advisor,

contemplated by this Agreement shall be subject to the satisfaction at or
prior to the Closing Date of the following conditions:

          (a)  No Injunction, etc.  At the Closing Date, there shall be no
injunction, restraining order or decree of any nature of any court or
Governmental Authority of competent jurisdiction that is in effect that
restrains or prohibits the consummation of the Stock Purchase or the transfer
to Buyer by Seller or the Subsidiaries of any Assets, except for the transfer
of any Assets or Subsidiary Stock the failure of which to transfer,
individually or in the aggregate with all other Assets and Subsidiary Stock
not being transferred on the Closing Date, would not be material to the
operations of the Analytical Instruments Business.  For purposes of this
Section 5.1(a), any failure to transfer shall not be regarded as material to
the operations of the Analytical Instruments Business so long as the
aggregate revenue for the fiscal year ended June 30, 1998 of all the Assets
not transferred does not exceed $20 million.  No legal action, suit or
proceeding, investigation or inquiry shall be pending by or on behalf of any
Governmental Authority wherein an unfavorable judgment, order, decree,
stipulation, ruling, decision or injunction would (i) prevent the
consummation of the sale of any material portion of the Assets or Subsidiary
Stock as contemplated hereby or (ii) cause the sale of any material portion
of the Assets or Subsidiary Stock as contemplated by this Agreement to be
rescinded following consummation.  No legal action, suit or proceeding by or
on behalf of any other Person shall be pending as to which there is a
reasonable likelihood of an outcome that would (A) prevent the consummation
of the sale of any material portion of the Assets or Subsidiary Stock as
contemplated hereby or (B) cause the sale of any material portion of the
Assets or Subsidiary Stock as contemplated by this Agreement to be rescinded
following consummation.

          (b)  Regulatory Authorizations.  All consents, approvals,
authorizations and orders of federal, state and foreign Governmental
Authorities set forth in, or required to be set forth in, Section 3.1(c) of

<PAGE>

the Seller Schedule (the "Required Consents") shall have been obtained, and
all applicable waiting periods specified under the HSR Act or any similar
foreign law or regulation with respect to the transactions contemplated by
this Agreement shall have lapsed or been terminated, except for Required
Consents of state and foreign Governmental Authorities the failure of which
to obtain, individually or in the aggregate, would not, in the reasonable
opinion of Buyer, be material to the operations of the Analytical Instruments
Business.

          (c)  Third Party Consents.  All consents, approvals and waivers of
third parties set forth in, or required to be set forth in, Section 3.1(c) of
the Seller Schedule, or that would have been required to be set forth in
Section 3.1(c) of the Seller Schedule in the case of agreements entered into
subsequent to the date of this Agreement, shall have been obtained by Seller,
except for any thereof the failure of which to obtain, individually or in the
aggregate, would not, in the reasonable opinion of Buyer, be material to the
operations of the Analytical Instruments Business.

          5.2. Conditions Precedent to Obligations of Buyer.  The obligations
of Buyer under this Agreement are subject to the satisfaction (or waiver in
writing by Buyer) at or prior to the Closing Date of each of the following
conditions:

          (a)  Accuracy of Representations and Warranties.  All
representations and warranties of Seller qualified as to materiality
contained herein or in any certificate or document delivered to Buyer
pursuant hereto shall be true and correct in all respects and those not so
qualified shall be true and correct in all material respects, in each case on
and as of the Closing Date, with the same force and effect as though such
representations and warranties had been made on and as of the Closing Date,
except as contemplated or permitted by this Agreement and except to the
extent that any such representation or warranty is made as of a specified
date, in which case such representation or warranty shall have been true and
correct as of such date;  provided that notwithstanding the foregoing, in the
event the representations and warranties of Seller referred to in this
Section 5.2(a) fail to be true and correct as of the Closing or such
specified date as of which such representations and warranties are made, the
condition set forth in this Section 5.2(a) shall be deemed satisfied unless a
Material Adverse Closing Event shall have occurred; and provided further that
the deemed satisfaction of such condition referred to in the preceding
proviso shall in no way constitute a release of Seller or a waiver of Buyer's
right to indemnification from Seller with respect to any such Damages
pursuant to Section 9.4 hereof.

          (b)  Performance of Agreements.  Seller shall have performed in all
material respects all obligations and agreements, and complied in all


                                     -52-

Closing Date, with the same force and effect as though such representations
and warranties had been made on and as of the Closing Date, except as
contemplated or permitted by this Agreement and except to the extent that any
such representation or warranty is made as of a specified date, in which case
such representation or warranty shall have been true and correct as of such
date;

          (b)  Performance of Agreements.  Buyer shall have performed in all

6.   Employee Relations and Benefits

          6.1. Pre-Closing Conduct; Other Liabilities.  (a)  Certain
Severance Benefits; Certain Arrangements.  In the event that the employment
of an employee of the Analytical Instruments Business who is eligible for
coverage immediately prior to the Closing Date under Seller's severance plans
for Asset Employees and employees of the Transferred Subsidiaries, as
described in Section 6.1(a)(i) of the Seller Schedule (collectively, the
"Seller's Severance Plans"), and who continues employment with the Analytical
Instruments Business without interruption (a "Continuing Employee"), is
terminated by Buyer after the Closing Date other than for cause, Buyer shall
pay such terminated employee severance benefits in accordance with the terms
of Buyer's severance plan, giving credit for the time served as employees of
the Company; provided that Buyer shall not be liable for severance for the
persons listed on Section 6.1(a)(ii) of the Seller Schedule.  Service with
Seller, the Subsidiaries and Buyer for periods prior to and after the Closing
Date shall be aggregated for purposes of calculating severance benefits for
such employees. To the extent permitted by applicable law, Seller shall use
its reasonable best efforts, prior to the Closing, to amend, or cause to be
amended, every severance plan or arrangement, to the extent that it would be
reasonably likely to give rise to eligibility for severance benefits for
Continuing Employees with respect to any termination of employment which
arises solely because of the consummation of the transaction contemplated by
this Agreement, so as to reduce or eliminate to the extent possible such
eligibility.  Under no circumstances shall Buyer be liable for payment of
severance benefits which arise from the operation of law or otherwise as a
result of the consummation of the transactions contemplated by this
Agreement.



                                     -54-

<PAGE>

          (b)  United States Pension and Retirement Plans. (i)  Cessation of
Benefit Accruals and Full Vesting.  Effective as of the Closing Date, the
Company shall cease benefit accruals under (i) The Employee Pension Plan of
The Perkin-Elmer Corporation  ("Seller Plan") and (ii) The Employee Savings
Plan of The Perkin-Elmer Corporation (the "Seller 401(k) Plan") with respect
to those participants in the Seller Plan and the Seller 401(k) Plan who are
United States Employees, and all benefits accrued by such United States
Employees, as of the Closing Date, in the Seller Plan and the Seller 401(k)
Plan shall be fully vested as of the Closing Date.  No assets or liabilities
shall be transferred from the Seller Plan or the Seller 401(k) Plan to any
employee benefit plan of Buyer.

          (ii)      Seller 401(k) Plan.  Seller and Buyer shall cooperate to
     take whatever steps are necessary to effect, as promptly as practicable
     after the Closing Date, to the extent elected by participants, the
     distribution and direct rollover to Buyer's 401(k) Plan of the accrued
     benefit as of the Closing Date of United States Employees under the
     Seller 401(k) Plan.  With respect to such rollover:  (i) Buyer shall
     provide to Seller written assurances that Buyer's 401(k) Plan is an
     "eligible retirement plan" and (ii) Seller shall provide to Buyer
     written assurances that the Seller 401(k) Plan are or are part of an
     "eligible retirement plan."  For purposes of this Section 6.1(b), the
     term "eligible retirement plan" shall have the meaning set forth in
     Sections 401(a)(31)(D) and 402(c)(8)(B) of the Code.  Buyer shall
     indemnify Seller in accordance with Section 9.4 against any losses
     incurred by it as a result of the failure of Buyer's 401(k) Plan to
     qualify as an "eligible retirement plan."  Similarly, Seller shall
     indemnify Buyer in accordance with Section 9.4 against any losses
     incurred by it as a result of the failure of Seller 401(k) Plan to
     qualify as an "eligible retirement plan."

          (iii)     Retiree Medical.  If an employee of the Company is
     entitled on or prior to the Closing Date to elect the retiree medical
     coverage under a Seller Benefit Plan, such employee may elect to receive
     such coverage under the terms of the Seller Benefit Plan as in effect on
     the Closing Date commencing either at the Closing Date or upon
     termination of the employee's employment with Buyer or one of its
     Affiliates on or prior to attaining age 65.  Such electing employee
     shall not be required to pay for coverage during the period of
     employment with Buyer or one of its Affiliates so long as such employee
     has not yet commenced receiving coverage under such Seller Benefit Plan.

          (c)  Additional Provisions Relating to Employees.  (i)  Employee
Transfer.  Buyer shall make offers of employment, to be effective as of the
Closing Date, to all domestic and foreign employees (collectively, the "Asset
Employees") of the Asset Sellers identified in Section 6.1(c) of the Seller
Schedule (adjusted to reflect terminations and hirings in the Ordinary Course

                                     -55-

<PAGE>

of Business from the date hereof and finalized at least 10 days prior to the
Closing Date and delivered to Buyer).  The employees who accept such offer of
employment made by Buyer, or are automatically transferred to Buyer shall be
referred to as, the "Transferred Employees").  Except as may be required by
applicable laws, Buyer shall have no obligation to offer employment to
individuals who are not actively at work on the Closing Date or absent from
work due to approved leaves of absence unless or until any such person
returns from such inactivity or leave.  At such time, Buyer shall be
obligated to offer employment to such person or, if no job is then available,
be liable for any severance to which person would be entitled.  For purposes
of this Agreement, "actively at work" means employees who are not on long-
term disability or who are not eligible for long-term disability but have
been continuously absent from work for a period exceeding 60 days and not
expected to return prior to the Closing Date.  Without limiting Buyer's
obligations under any other provision of this Section 6, Buyer's offers of
employment shall be at least at the current wage or salary rate for such
employees.

          (ii)  Starting on the Closing Date, Buyer shall, for a period
     ending on the date twelve (12) months after the Closing Date, provide
     each Continuing Employee who continues his or her employment after the
     Closing Date with total cash compensation at least equal to such
     Continuing Employee's total cash compensation during the twelve months
     immediately prior to the Closing Date.  Starting on the Closing Date,
     Buyer shall also, for a period ending on the date twelve (12) months
     after the Closing Date, maintain (or cause its subsidiaries to maintain)
     employee benefit plans, agreements, programs, policies and arrangements
     for the benefit of each Continuing Employee that are no less favorable
     in the aggregate to those provided by Buyer to its employees who are
     similarly situated to such Continuing Employee ("Buyer Plans").
     Notwithstanding anything to the contrary in this Agreement, starting on
     the Closing Date Buyer shall, for a period ending on the date twelve
     (12) months after the Closing Date, maintain (or cause its subsidiaries
     to maintain) a severance pay plan, program or practice for the benefit
     of each Continuing Employee that is no less favorable than the Seller's
     Severance Plans in effect immediately prior to the Closing Date with
     respect to such Continuing Employee.

          (iii)     Buyer acknowledges that the Acquired Rights Directive
     (77/187 EEC) as enacted in the Member States of the European Union and
     similar laws in other jurisdictions which safeguard the rights of
     employees in transfers of undertakings, businesses or parts of
     businesses (collectively, the "Transfer Laws") may operate to
     automatically transfer all or some of the Asset Employees to Buyer.
     Buyer agrees that it will comply with the Transfer Laws, if any, of any
     jurisdiction in which the Asset Employees are employed.  Buyer agrees
     that after the Closing Date, the contracts of employment of the

                                     -56-

<PAGE>

     Transferred Employees (except for any rights or obligations which do not
     transfer under the Transfer Laws, or are not otherwise assumed by
     Buyer), if any, will have effect as if originally entered into between
     Buyer and the Transferred Employees.

          (d)  Other Employee Benefits Matters.  (i) Service Credit.  Under
Buyer's employee benefit plans, arrangements and policies, each employee of
the Analytical Instruments Business who continues employment with the
Analytical Instruments Business after the Closing without interruption shall
receive credit for service accrued or deemed accrued prior to the Closing
Date with Seller, any Subsidiary or any of their respective Affiliates for
all purposes of such plans (except for purposes of benefit accruals under
pension and post-retirement benefit plans), and shall be entitled to
participate in any such employee benefit plans.  Buyer shall also permit the
employees of the Analytical Instruments Business and their eligible
dependents to participate in its group health plans, and shall waive any
waiting periods and any restrictions and limitations on preexisting medical
conditions.

          (ii)      Plant Closing Laws.  After the Closing Date, Buyer shall
     be responsible for providing any notice of layoff or plant closing, as
     may be required, with respect to the Analytical Instruments Business
     after the Closing pursuant to the United States Federal Worker
     Adjustment and Retraining Notification Act of 1988, any successor United
     States federal law, and any applicable plant closing notification Law.

          (iii)     Post-Closing Benefits.  Until December 31, 1999, Buyer
     shall continue for employees "actively at work" (as defined herein)
     healthcare and welfare benefits that are comparable or similar to those
     benefits under Seller's plan as of the Closing Date for continuing
     employees.  Seller agrees to cooperate with Buyer to facilitate the
     coordination of such benefits during such period provided that Buyer
     shall have no obligation to provide post-termination life insurance.

          (iv)      UK Pension Plan.  With respect to the defined benefit
     pension plan of Perkin-Elmer Ltd. maintained or contributed to by the
     Company (the "UK Pension Plan"), Seller shall pay on the Closing Date to
     Buyer the sum of (Pound Sterling) 2.1 million in respect of agreements
     reached between Seller and Buyer concerning the UK Pension Plan and on
     or after the Closing Date, Buyer shall assume and become the sponsor of
     the UK Pension Plan and have responsibility for all liabilities,
     obligations and costs arising out of or in connection with the UK
     Pension Plan.

          (v)       Accrued Vacation. Buyer shall, or shall cause the
     Transferred Subsidiary to, provide for Employees of the Analytical
     Instruments Business to take their accrued vacations after the Closing

                                     -57-

<PAGE>

     Date, in such manner and at such times as is consistent with Seller's
     past practices and not disruptive of the Analytical Instruments
     Business.

          (vi)      Consultation Requirements.  Seller and Buyer shall
     cooperate to take whatever steps are reasonably necessary to comply with
     any employee consultation requirements arising under any applicable law.

          (vii)     No Liability.  Other than as expressly assumed in this
     Article 6, Buyer shall not be liable for any benefits under any Seller
     Benefit Plan which is not maintained by the Company after the Closing or
     under any Benefit Plan ever maintained by the Company.  Buyer shall not
     be liable for long-term disability benefits nor any other benefit
     payable for Asset Employees who are not "actively at work" (as defined
     herein) on or prior to the Closing Date.  Buyer shall not be liable for
     any health care continuation benefits for employees who terminated
     employment on or prior to the Closing Date.

          (viii)    Retention of Liabilities by Seller.  Seller and the
     Subsidiaries shall retain all pension obligations under the Seller Plan
     with respect to Employees of the Analytical Instruments Business which
     accrue up to and including the Closing Date.  Benefits relating to such
     pension obligations shall be provided by Seller and the Subsidiaries to
     Employees under the terms of the Seller Plan, based only upon the
     Employee's credited service with Seller and the Subsidiaries and
     measured by the applicable benefit formula in effect on the Closing
     Date, and subject to all other terms, conditions and limitations of the
     Seller Plan in effect on the Closing Date.

          (ix)       Co-Operations.  Buyer and Seller agree to cooperate to
     obtain any amendments of any of the collective bargaining agreements
     which may be necessary to implement the provisions of this Agreement.

7.   Termination

          7.1. General.  This Agreement may be terminated and the
transactions contemplated herein may be abandoned, (a) by mutual written
consent of Buyer and Seller or (b) by Buyer or Seller by written notice to
the other party in the event that the Closing Date shall not have occurred on
or before October 31, 1999; provided, however, that if the Closing Date shall
not have occurred on or before such date due to the act or omission of Buyer
or Seller, then that party may not terminate the Agreement.  This Agreement
may also be terminated and the transactions contemplated herein abandoned by
either Buyer or Seller by written notice to the other party, in the event a
Material Adverse Closing Event has occurred.  As used in this Agreement, a
"Material Adverse Closing Event" means that (i) the representations and
warranties of Seller have failed to be true and correct as of the Closing or

                                     -58-

<PAGE>

such earlier date on which such representations and warranties are made and
(ii) the Damages therefore reasonably expected to result from such failure
equal or exceed $40 million.

          7.2. Obligations in Event of Termination.  In the event of any
termination of the Agreement as provided in Section 7.1, this Agreement shall
forthwith become wholly null and void and of no further force and effect and
there shall be no liability on the part of Buyer or Seller, except that the
obligations of the parties under Section 4.1 with respect to confidentiality
and Section 9.2 and this Section 7.2 shall remain in full force and effect,
and except that termination shall not preclude any party from suing the other
party for breach of this Agreement.

8.   Transactions and Activities Subsequent to Closing

          8.1. Access to Books and Records; Confidentiality.  (a)  For a
period of  ten (10) years following the Closing Date, Buyer shall retain and
afford, and will cause its Affiliates to retain and afford, to Seller and its
Subsidiaries, including the Subsidiary Asset Sellers, their counsel and their
accountants, during normal business hours and upon reasonable advance notice,
reasonable access to the books, records and other data of the Analytical
Instruments Business and of the Transferred Subsidiaries (including, without
limitation, any books, records or other data that may be reasonably requested
by Seller in connection with any audit described in Section 8.4(c)) with
respect to the period prior to the Closing Date and, in the case of any
Transferred Subsidiary, with respect to the applicable current taxable
period, to the extent that such access may be reasonably required by Seller
or any Subsidiary Asset Seller to facilitate (i) the preparation and timely
filing by Seller or such Subsidiary Asset Seller of such Tax Returns as it
may be required to file with respect to the operations of the Analytical
Instruments Business or the preparation and timely filing of such Tax Returns
as Seller shall bear responsibility for preparing pursuant to Section 8.4,
the making of any election related to Taxes or in connection with any audit,
amended return, claim for refund or any suit or proceeding with respect
thereto, (ii) the investigation, litigation and final disposition of any
claims, suits or proceedings which may have been or may be made against
Seller or such Subsidiary Asset Seller by third parties in connection with
the Analytical Instruments Business and (iii) the payment of any amount
pursuant to Section 9.4 or in connection with any liabilities or obligations
which have not been assumed by Buyer under this Agreement.  Buyer will not,
and will cause its Affiliates not to, dispose of, alter or destroy any such
books, records and other data without giving thirty (30) days' prior notice
to Seller to permit Seller, at its expense, to examine, duplicate or
repossess such records, files, documents and correspondence.

          (b)  Buyer shall further cooperate with Seller in the preparation
for and prosecution of the defense of any audit, claim, action or cause of

                                     -59-

<PAGE>

action arising out of or relating to any Excluded Liabilities which have not
been assumed by Buyer under this Agreement including, without limitation, by
making available evidence within the control of Buyer and Persons needed as
witnesses employed by Buyer, in each case as reasonably needed for such
defense.  Seller shall reimburse Buyer for its reasonable out-of-pocket costs
relating to its cooperation under this subparagraph.

          (c)  For a period of ten (10) years following the Closing Date,
Seller shall retain and afford, and will cause the Subsidiary Asset Sellers
to retain and afford, to Buyer, its counsel and its accountants, during
normal business hours and upon reasonable advance notice, reasonable access
to the books, records and other data of Seller and the Subsidiary Asset
Sellers with respect to the period prior to the Closing Date to the extent
that such access may be reasonably required by Buyer or any Affiliate of
Buyer to facilitate (i) the preparation by Buyer or such Affiliate of such
Tax Returns as it may be required to file with respect to the operations of
the Analytical Instruments Business, the making of any election related to
Taxes or in connection with any audit, amended return, claim for refund or
any suit or proceeding with respect thereto, (ii) the investigation,
litigation and final disposition of any claims, suits or proceedings which
may have been or may be made against Buyer or such Affiliate by third parties
in connection with the Analytical Instruments Business and (iii) the payment
of any amount pursuant to Section 9.4 or in connection with any liabilities
or obligations which have been assumed by Buyer under this Agreement.  Seller
will not, and will cause its Affiliates not to, dispose of, alter or destroy
any such books, records and other data without giving thirty (30) days' prior
notice to Buyer to permit Buyer, at its expense, to examine, duplicate or
repossess such records, files, documents and correspondence.

          (d)  Seller further agrees to cooperate with Buyer in the
preparation for and prosecution of the defense of any audit, claim, action or
cause of action arising out of or relating to any liability which has been
assumed by Buyer hereunder, including, without limitation, by making
available evidence within the control of Seller and Persons needed as
witnesses employed by Seller, in each case as reasonably needed for such
defense.  Buyer shall reimburse Seller for its reasonable out-of-pocket costs
relating to its cooperation under this subparagraph.

          8.2. Further Agreements.  Seller authorizes and empowers Buyer on
and after the Closing Date to receive and open all mail received by Buyer
relating to the Analytical Instruments Business, the Transferred Subsidiaries
or the Assets and to deal with the contents of such communications in any
proper manner.  Seller shall, and shall cause other Asset Sellers to,
promptly deliver to Buyer any mail or other communication received by them
after the Closing Date pertaining to the Analytical Instruments Business, the
Transferred Subsidiaries or the Assets and any cash, checks or other
instruments of payment to which Buyer is entitled.  Buyer shall promptly

                                     -60-

<PAGE>

deliver to Seller any mail or other communication received by it after the
Closing Date pertaining to the assets and liabilities described in Sections
1.3 and 1.7, and any cash, checks or other instruments of payment in respect
thereof.

          8.3. Asset Returns.  In the event Buyer receives any assets of the
Company that are not intended to be transferred pursuant to the terms of this
Agreement, Buyer agrees to promptly return such assets to Seller at Seller's
expense.  In the event any payments are made to Buyer following the Closing
with respect to Accounts Receivable that are not attributable to the
Analytical Instruments Business or that relate to any Excluded Assets or
Excluded Liabilities, Buyer agrees to forward such payments to Seller
promptly.  In the event any payments are made to Seller following the Closing
with respect to Accounts Receivable that are attributable to the Analytical
Instruments Business or that relate to any Assets or Assumed Liabilities,
Seller agrees to forward such payments to Buyer promptly.  In the event that,
following the Closing, Seller or any of the Subsidiaries receives any assets
that were intended to be, but were not, transferred pursuant to this
Agreement at the Closing, Seller shall promptly notify Buyer to such effect
and shall comply with its obligations in respect thereof contemplated by
Section 1.5.

          8.4. Certain Tax Matters.  (a)  Seller shall prepare, or cause to
be prepared, all Tax Returns in respect of the Transferred Subsidiaries for
all taxable periods ending on or prior to the Closing Date and all taxable
periods beginning prior to the Closing Date and ending after the Closing
Date.  In the case of any such Tax Return that is filed after the Closing
Date, Buyer shall deliver to Seller at least 60 days prior to the due date
for filing the relevant Tax Return a true and correct accounting of all
relevant Tax Items (as defined below) relating to the applicable Transferred
Subsidiary for the taxable period.  Seller shall submit any part of such Tax
Return relating to a Transferred Subsidiary to Buyer at least 30 days prior
to the date on which the Tax Return is due (including extensions).  Buyer
shall submit its comments to Seller within 14 days of receipt of the relevant
portions of such Tax Return.  If such Tax Return relates to a period ending
on or prior to the Closing Date, Seller shall not be required to alter the
Tax Return to reflect such comments unless Buyer receives an opinion of
counsel, which counsel shall be reasonably acceptable to Seller, to the
effect that failure to make such alteration would create a significant risk
of imposition of a penalty on Buyer or any Transferred Subsidiary.  If such
Tax Return relates to a period ending after the Closing Date, Seller and
Buyer agree to consult and resolve in good faith any issue arising as a
result of Buyer's review of such Tax Return and mutually to consent to the
filing as promptly as possible of such Tax Return.  In the event the parties
are unable to resolve any dispute, the parties shall jointly request that a
mutually acceptable accounting firm which is not the past or then current
principal auditors of Buyer or Seller resolve any issue before the due date

                                     -61-

<PAGE>

of any such Tax return, in order that such Tax return may be timely filed.
The scope of the accounting firm's review shall be limited to the disputed
items.  Seller and Buyer shall each pay one-half of the accounting firm's
fees and expenses.  The term "Tax Item" shall mean any item of income,
capital gain, net operating loss, deduction, credit or other Tax attribute
relevant to the calculation of Tax liability.

          (b)  Buyer shall timely file, or cause to be timely filed, all Tax
Returns prepared pursuant to this Section 8.4 that are filed after the
Closing Date (other than any consolidated returns relating to pre-Closing tax
periods of any Transferred Subsidiary).  Buyer shall pay to the relevant
taxing authority all Taxes due in connection with any such Tax Return.  If,
pursuant to Section 9.4, Seller would be liable for any Taxes relating to
such Tax Return, Seller shall pay the amount of such Taxes to Buyer no later
than five (5) Business Days after the Tax Return is filed.

          (c)  Notwithstanding anything in this Agreement to the contrary,
Seller shall control the representation of the interests of Seller and any
Subsidiaries in any Tax audit or administrative or court proceeding relating
to Tax Returns with respect to which Seller may be liable for Taxes pursuant
to this Agreement; provided, however, that Seller will consult with Buyer
regarding any Tax issue of a Transferred Subsidiary that may have a
materially adverse effect on the Tax liability of Buyer, any of its
Affiliates or any Transferred Subsidiary for any period ending after the
Closing Date and, in such situation, Buyer shall have the right, at its
discretion, to participate in (but not to control) any such audit or
proceeding solely with respect to such Tax issue, provided that, in such
case, Buyer shall not communicate with any taxing authority in connection
with such audit or proceeding without the consent of Seller.  Buyer shall
have the right, at its discretion after good faith consultation with Seller,
to release Seller from its obligation to indemnify Buyer with respect to such
Tax issue by a written agreement mutually agreed to by Seller and Buyer and,
in that event, to control the representation of the interest of the relevant
Subsidiary solely with respect to such Tax issue.  Seller and Buyer shall
bear their own expenses with respect to their participation in any proceeding
under this Section 8.4(c).  Buyer and Seller mutually agree to consult and
cooperate with each other so that the transfer of control is effected in a
manner that will minimize any disruption to any such audit or proceeding and
so that Seller is not prejudiced in any way.

          (d)  Each of Seller and Buyer shall promptly notify the other party
in writing upon receipt by the notifying party, or any Affiliate of the
notifying party, of notice of any pending or threatened Tax audits or
assessments relating to Taxes covered by Section 8.4.




                                     -62-

<PAGE>

          (e)  Seller shall provide Buyer with such information as is
necessary for the application of the incremental research credit provisions
of Code section 41(f)(3)(A).

          (f)  The parties agree that any indemnification payments made
pursuant to this Agreement shall be treated for tax purposes as an adjustment
to the Purchase Price, unless otherwise required by applicable law.  Buyer
agrees not to make any election under Section 338 of the Code (other than
with respect to BSW) unless Seller consents to such election in writing which
consent shall not be unreasonably withheld.

          8.5. Non-Solicitation of Employees.  (a)  During the period
beginning on the Closing Date and ending on the fifth anniversary of the
Closing Date, without the prior written consent of Buyer, Seller shall
refrain from, either alone or in conjunction with any other Person (including
any Affiliate), directly or indirectly:

          (i)  soliciting the employment by Seller or any of its Affiliates
     of any Transferred Employee unless such Transferred Employee is
     terminated by Buyer; or

          (ii) causing or attempting to cause any Transferred Employee to
     resign or sever a relationship with Buyer or any of its subsidiaries
     (including the Transferred Subsidiaries).

          (b)  During the period beginning on the Closing Date and ending on
the fifth anniversary of the Closing Date, without the prior written consent
of Seller, Buyer shall refrain from, either alone or in conjunction with any
other Person (including any Affiliate), directly or indirectly:

          (i)  soliciting the employment by Buyer or any of its Affiliates of
     any Person who is an employee of Seller or any of the Subsidiaries other
     than Transferred Employees unless such employee is terminated by Seller;
     or

          (ii) causing or attempting to cause any employee of Seller or any
     of its subsidiaries other than Transferred Employees to resign or sever
     a relationship with Seller or any of the Subsidiaries.

          (c)  The parties agree that the foregoing restrictions in
subsections (a) and (b) shall not apply to any general solicitation by Buyer
or Seller not specifically directed at employees of Seller or Transferred
Employees made in a newspaper or other periodical.

Date and ending on the third anniversary of the Closing Date, without the
prior written consent of Buyer, Seller shall refrain from, either alone or in

<PAGE>

conjunction with any other Person (including any Affiliate), directly or
indirectly, manufacturing, distributing, servicing or selling products or
their successor products that are the same or substantially similar to those
manufactured, distributed and/or sold by the Analytical Instruments Business
or under development as of the date of this Agreement, solely as such
products are specifically listed in Section 8.6(a) of the Seller Schedule
(the "Analytical Instruments Products"), in any field of use listed in
Section 8.6(b) of the Seller Schedule, or in any field of use other than Life
Sciences (as defined below) listed in Section 8.6(c) of the Seller Schedule,
to the extent (but only to the extent) that Seller and its subsidiaries
(exclusive of the Analytical Instruments Business), as of the date of this
Agreement, are not manufacturing, producing, developing, distributing or
selling such products in such fields, and have no pending plans to do so (the
"Excluded Fields").  Buyer expressly acknowledges that Seller shall not be in
violation of this Section 8.6 if it develops or sells products listed in
Section 8.6(a) of the Seller Schedule for applications outside the fields of
use set forth in Section 8.6(b) of the Seller Schedule. Buyer further
acknowledges that the foregoing provisions of this Section 8.6 shall not be
construed to prohibit any Person that becomes a controlling Affiliate of
Seller following the Closing Date from continuing to engage in any business
in which it is engaged at the time it becomes such a controlling Affiliate.
As used in Section 8.6(c) of the Seller Schedule, "Life Sciences" means the
measurement, creation or purification of substances for the purpose of
characterizing and/or altering biological organisms, or constituents thereof.
Life Sciences does not include material science or petroleum analysis.

as a result of any breach by Seller of its representations and warranties
contained herein; provided, that (x) Seller shall be required to indemnify

<PAGE>

          (b)  Buyer shall indemnify and hold Seller and the other Asset
Sellers harmless against and in respect of (i) all obligations and
liabilities of Seller and the other Asset Sellers expressly assumed by Buyer
pursuant to this Agreement or the Assumption Agreement; (ii) any actual
Damages incurred or sustained by Seller or the other Asset Sellers as a
result of any breach by Buyer of its covenants contained herein; (iii) any

such breaches if, and only to the extent that, the aggregate actual Damages
(as adjusted pursuant to Section 9.4(e)) resulting from such breaches to
Seller and the Subsidiary Asset Sellers exceeds $4,600,000, (y) Buyer shall
not be required to indemnify Seller and the Subsidiary Asset Sellers pursuant
to this clause (iv) in an aggregate amount in excess of $425 million, and
(z) any claim for indemnification under this clause (iv) must be made in
writing with reasonable specificity to Buyer by Seller prior to the

obligations of Seller or any of the Subsidiaries (other than the Transferred

Analytical Instruments Business as to which no substitution has been effected
pursuant to Section 4.4 prior to the Closing.

          (c)  With respect to third-party claims, all claims for
indemnification by Buyer or Seller, as the case may be (an "Indemnified
Party"), hereunder (other than claims specifically addressed in Section
8.4(c)) shall be asserted and resolved as set forth in this Section 9.4(c).
In the event that any written claim or demand for which Buyer or Seller, as
the case may be (an "Indemnifying Party"), would be liable to any Indemnified
Party hereunder is asserted against or sought to be collected from any
Indemnified Party by a third party, such Indemnified Party shall promptly
notify the Indemnifying Party of such claim or demand and the amount or the
estimated amount thereof to the extent then feasible (which estimate shall
not be conclusive of the final amount of such claim or demand) (the "Claim
Notice").  The Indemnifying Party shall have thirty (30) days from the date
of receipt of the Claim Notice (the "Notice Period") to notify the
Indemnified Party (A) whether or not the Indemnifying Party disputes the
liability of the Indemnifying Party to the Indemnified Party hereunder with
respect to such claim or demand and (B) whether or not it desires to defend
the Indemnified Party against such claim or demand.  All costs and expenses
incurred by the Indemnifying Party in defending such claim or demand shall be
a liability of, and shall be paid by, the Indemnifying Party.  Except as

                                     -66-

<PAGE>

hereinafter provided, in the event that the Indemnifying Party notifies the
Indemnified Party within the Notice Period that it desires to defend the
Indemnified Party against such claim or demand, the Indemnifying Party shall
have the right to defend the Indemnified Party by appropriate proceedings and
shall have the sole power to direct and control such defense.  If any
Indemnified Party desires to participate in any such defense, it may do so at
its sole cost and expense.  The Indemnified Party shall not settle a claim or
demand without the consent of the Indemnifying Party.  The Indemnifying Party
shall not, without the prior written consent of the Indemnified Party,
settle, compromise or offer to settle or compromise any such claim or demand
on a basis which would result in the imposition of a consent order,
injunction or decree which would restrict the future activity or conduct of
the Indemnified Party or any subsidiary or Affiliate thereof or if such
settlement or compromise does not include an unconditional release of the
Indemnified Party for any liability arising out of such claim or demand.  If
the Indemnifying Party elects not to defend the Indemnified Party against
such claim or demand, whether by not giving the Indemnified Party timely
notice as provided above or otherwise, then the amount of any such claim or
demand or, if the same be contested by the Indemnified Party, that portion
thereof as to which such defense is unsuccessful (and the reasonable costs
and expenses pertaining to such defense) shall be the liability of the
Indemnifying Party hereunder, subject to the limitations set forth in
Sections 9.4(a) and 9.4(b).  Buyer and Seller shall each render to each other
such assistance as may reasonably be requested in order to insure the proper
and adequate defense of any such claim or proceeding.

          (d)  The indemnities provided in this Section 9.4 shall survive the
Closing.  Except with respect to claims based on actual fraud, the indemnity
provided in this Section 9.4 shall be the sole and exclusive remedy of the
Indemnified Party against the Indemnifying Party at law or equity for any
matter covered by paragraphs (a) and (b) above.

          (e)  The amount of any Damages for which indemnification is
provided under this Section 9.4 shall be computed net of any insurance
proceeds received by the Indemnified Party in connection with such Damages.
If the amount with respect to which any claim is made under this Section 9.4
(an "Indemnity Claim") gives rise to a currently realizable Tax Benefit (as
defined below) to the party making the claim, the indemnity payment shall be
reduced by the amount of the Tax Benefit available to the party making the
claim.  Any indemnity payment made pursuant to an Indemnity Claim shall be
increased to take account of any net Tax cost incurred by the claiming party
arising from the receipt of indemnity payments hereunder.  To the extent such
Indemnity Claim does not give rise to a currently realizable Tax Benefit, if
the amount with respect to which any Indemnity Claim is made gives rise to a
subsequently realized Tax Benefit to the party that made the claim, such
party shall refund to the Indemnifying Party the amount of such Tax Benefit
when, as and if realized.  For the purposes of this Agreement, any

                                     -67-

<PAGE>

subsequently realized Tax Benefit shall be treated as though it were a
reduction in the amount of the initial Indemnity Claim, and the liabilities
of the parties shall be redetermined as though both occurred at or prior to
the time of the indemnity payment.  For purposes of this Section 9.4(e), a
"Tax Benefit" means an amount by which the tax liability of the party (or
group of corporations including the party) is reduced (including, without
limitation, by deduction, reduction of income by virtue of increased tax
basis or otherwise, entitlement to refund, credit or otherwise) plus any
related interest received from the relevant taxing authority.  Where a party
has other losses, deductions, credits or items available to it, the Tax
Benefit from any losses, deductions, credits or items relating to the
Indemnity Claim shall be deemed to be realized proportionately with any other
losses, deductions, credits or items.  For purposes of this Section 9.4(e), a
Tax Benefit is "currently realizable" to the extent it can be reasonably
anticipated that such Tax Benefit will be realized in the current taxable
period or year or in any Tax Return with respect thereto (including through a
carryback to a prior taxable period) or in any taxable period or year prior
to the date of the Indemnity Claim.  In the event that there should be a
determination disallowing the Tax Benefit, the Indemnifying Party shall be
liable to refund to the Indemnified Party the amount of any related reduction
previously allowed or payments previously made to the Indemnifying Party
pursuant to this Section 9.4(e).  The amount of the refunded reduction or
payment shall be deemed a payment under this Section 9.4 and thus shall be
paid subject to any applicable reductions under this Section 9.4(e).

          (f)  The parties agree that any indemnifications payments made
pursuant to this Agreement shall be treated for tax purposes as an adjustment
to the Purchase Price, unless otherwise required by applicable law.

          (g)  Each Indemnified Party shall be obligated in connection with
any claim for indemnification under this Section 9.4 to use all reasonable
efforts to mitigate Damages upon and after becoming aware of any event which
could reasonably be expected to give rise to such Damages.  Without limiting
the foregoing, otherwise indemnified Damages under or relating to
Environmental Laws shall be indemnified hereunder only to the extent such
Damages were reasonably required to be incurred under Environmental Laws.

          (h)  Notwithstanding anything to the contrary contained herein,
neither party hereto nor any Affiliate of either of them shall be liable for
any consequential, punitive or special damages pursuant to this Agreement or
any of the agreements contemplated hereby (it being understood, however, that
lost revenues or income may, if otherwise appropriate, be utilized in the
valuation of Assets or Subsidiary Stock for purposes of the calculation of
any Damages, except to the extent a party to this Agreement or any of its
Affiliates is liable for such consequential, punitive or special damages to a
third party.


                                     -68-

          (i)  Buyer shall promptly pay to Seller any refund or credit
(including any interest paid or credited with respect thereto) received by
Buyer, any Transferred Subsidiary or any Affiliate thereof after the Closing
of Taxes relating to any taxable period ending on or before the Closing Date
or, with respect to any taxable period beginning before and ending after the
Closing Date, Taxes relating to the portion of such period beginning before
and ending on the Closing Date determined as provided in Section 9.4(a)(iv).
Buyer shall, if Seller reasonably so requests, cause the relevant Transferred
Subsidiary (or other related entity) to file for any refund or credit to
which Seller believes it is entitled under this Section 9.4(i).

          9.5. Environmental Remediations.  (a)  After the Closing, Seller
and Buyer shall equally share the cost of any investigation, monitoring,
clean-up or other remediation of any release of Materials of Environmental
Concern ("Environmental Remediation") at or from any Plant or any real
property currently owned by any Transferred Subsidiary or leased by any
Transferred Subsidiary from any third party to the extent any such
Environmental Remediation: (i) relates to events or conditions occurring or
existing on or prior to the Closing Date and (ii) is reasonably required by
Environmental Laws; provided that in no event shall Buyer's obligations
pursuant to this Section 9.5(a) exceed $4 million in the aggregate.

          (b)  Seller shall perform all Environmental Remediations subject to
cost-sharing pursuant to Section 9.5 (a) hereof ("Shared Remediations").
Notwithstanding any provision of this Agreement to the contrary, Seller shall
have no obligation to perform or provide indemnification for any
Environmental Remediation, and Buyer shall be solely responsible for and
shall indemnify and hold harmless Seller and the Asset Sellers against any
Damages relating to, any Environmental Remediation at or relating to any
Plant or any real property currently owned by any Transferred Subsidiary or
leased by any Transferred Subsidiary from any third party to the extent such
Environmental Remediation is not a Shared Remediation.

          (c)  Seller and Buyer agree that any Shared Remediation shall be
undertaken and performed in the most cost-effective manner reasonably
acceptable to the Governmental Authority with jurisdiction over the Shared
Remediation.  Seller and Buyer shall cooperate and take all reasonable
actions to eliminate and minimize costs relating to any Shared Remediation,
including without limitation, if reasonably requested by Seller, Buyer shall
impose deed restrictions on properties subject to Shared Remediations
limiting such properties to future uses that will not result in materially
greater Environmental Remediation expenses than if such future uses were
restructured to industrial or commercial  uses.

          (d)  In any Shared Remediation, Seller shall have sole authority
over communications and negotiations with any Governmental Authority;
provided however, that Seller shall coordinate in advance with and obtain

                                     -69-

<PAGE>

approval from Buyer for such communication or negotiation, such approval not
to be unreasonable withheld, and Seller shall promptly provide Buyer with
copies of all written communications and a summary of all negotiations and
oral communications with Governmental Authorities relating to Shared
Remediations.

          (e)  Buyer agrees that upon reasonable prior notice to Buyer,
Seller and Seller's agents and representatives shall have the right to enter
upon any property at which a Shared Remediation is being undertaken, or is
proposed to be undertaken, in order to initiate, implement or complete any
Shared Remediation.  Seller shall use all reasonable efforts to conduct all
Shared Remediations in a manner which, to the extent practicable, avoids
interference with or minimizes any interference with Buyer's use of the
property subject to the Shared Remediation.

          9.6. Pre-Closing Litigation.  (a)  After the Closing, Seller and
Buyer shall equally share the cost of and Damages with respect to any action,
suit, proceeding, dispute, claim or investigation arising out of or related
to the operations of the Analytical Instruments Business which is filed or
commenced at any time after the date of this Agreement and prior to the
Closing against Seller or any of its Affiliates or which is set forth in
Section 9.6 of the Seller Schedule ("Pre-Closing Litigation"); provided that
in no event shall Buyer's obligations pursuant to this Section 9.6(a) exceed
$4 million in the aggregate; and provided further that in no event shall
Buyer's obligations with respect to Damages (other than attorneys fees and
costs of defense which shall in no way be limited except as set forth in the
preceding proviso) with respect to item 3 of Section 9.6 of the Seller
Schedule exceed $1 million.

          (b)  Seller and Buyer shall cooperate and take all reasonable
actions to eliminate and minimize any Damages relating to any Shared
Litigation.  Seller shall have the right to defend the Pre-Closing Litigation
by appropriate proceedings and shall have the sole power to direct and
control such defense (except for item 3 of Section 9.6 of the Seller
Schedule, which Buyer shall have sole power to direct and control)  subject
to cost-sharing pursuant to Section 9.6 (a) hereof ("Shared Litigation");
provided that in no event shall Seller (or Buyer, as the case may be) settle,
compromise or offer to settle or compromise any Shared Litigation without the
prior written consent of Buyer (or Seller, as the case may be) to all terms
of such settlement or compromise; and provided further that Buyer shall have
the right to defend against any Pre-Closing Litigation if Seller declines or
fails to do so in a timely manner.  Notwithstanding any provision of this
Agreement to the contrary, Seller shall have no obligation to perform or
provide indemnification for any Shared Litigation.  Buyer shall receive one-
half of any proceeds received by Seller in the final resolution after
exhaustion of available appeals of item 3 of Section 9.6 of the Seller
Schedule, up to a total payment to Buyer of $1 million. Buyer shall allow

                                     -70-

<PAGE>

intended to confer on any Person other than the parties hereto or their
respective successors and assigns, any rights, remedies, obligations or

this Agreement readily apparent shall be deemed to be an exception to such
representation or representations or to be disclosed on such other Schedule
or Schedules (or Exhibit or Exhibits), as the case may be, notwithstanding
the omission of a reference or cross-reference thereto.  Any fact or item
disclosed on any Schedule or Exhibit hereto shall not by reason only of such

reference in determining any standard of materiality under this Agreement.

          9.14.  Other Covenants.  In addition to Seller's obligations set
forth in Section 2.5 hereof, to the extent that any consents needed to assign
to Buyer any of the Assets have not been obtained on or prior to the Closing
Date, this Agreement shall not constitute an assignment or attempted

                                     -72-

<PAGE>

assignment thereof if such assignment or attempted assignment would
constitute a breach thereof.  If any such consent shall not be obtained on or
prior to the Closing Date, then (i) Seller and Buyer, if required under
applicable law, shall use their reasonable efforts in good faith to obtain
such consent as promptly as practicable thereafter and (ii) if in the
reasonable judgment of Buyer such consent may not be obtained, the parties
shall use reasonable efforts in good faith to cooperate, and to cause each of
their respective Affiliates to cooperate, in any lawful arrangement designed
to provide for Buyer the benefits under any such Assets.

Agreement shall be governed by, and construed in accordance with, the laws of
the State of New York.  Any suit, action or proceeding against any party with

sitting in the City of New York in the State of New York or in the
Commonwealth of Massachusetts or, if jurisdiction is lacking in such a court,
in a court of record in the State of New York or the Commonwealth of
Massachusetts, and each party hereto hereby irrevocably waives, to the
fullest extent permitted by law, any objection that it may have, whether now
or in the future, to the laying of venue in, or to the jurisdiction of, any
and each of such courts for the purpose of any such suit, action or
proceeding and further waives any claim that any such suit, action or
proceeding has been brought in an inconvenient forum, and each hereby submits
to such jurisdiction.

EG&G, Inc., a Massachusetts corporation ("Licensee").

          WHEREAS, pursuant to Section 1.2 of the Purchase Agreement and
Licensee dated as of March 8, 1999 ("Purchase Agreement"), Licensor has
agreed to sell to Licensee the assets of the Analytical Instruments Business

License Agreements include this Agreement, pursuant to which Licensor is
granting to Licensee a license to use the Intellectual Property (as defined
therein) set forth on Schedule 4.8(a) thereto and Exhibit A hereto; and

          WHEREAS, pursuant to Sections 5.2(d) and 5.3(e) of the Purchase
Agreement, Licensor and Licensee must execute and deliver this Agreement to
each other at or prior to the Closing Date (as defined therein):

          NOW, THEREFORE, in consideration of the premises and the mutual
promises and covenants contained herein and for other good and valuable
consideration (including that set forth in the Purchase Agreement), the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

          Article 1.  License Grant.

          Section 1.1.  Patents.  During the Term as set forth in Article 7,
Licensor hereby grants to Licensee a worldwide, non-exclusive, royalty-free
right and license to make, have made, use, import, distribute and sell
products under the United States and foreign patents and patent applications,
invention disclosures and other intellectual property rights listed on
Schedule A annexed hereto (the "Patents") in all fields of use except DNA and
protein analyses.  Licensor agrees that it shall, upon Licensee's request,
negotiate in good faith to execute a license to Licensee on commercially
reasonable terms to make, have made, use, import, distribute and sell
products under the Patents in the field of DNA and protein analyses.

          Section 1.2.  Know-How.  During the Term as set forth in Article 7,
Licensor hereby grants to Licensee a worldwide, non-exclusive, royalty-free
right and license to make, have made, use, import, distribute and sell

the Patents (the "Know-How").

          Section 1.3.  Software.  During the Term as set forth in Article 7,
and subject to the terms of the applicable Transition Agreement (as defined
in the Purchase Agreement), Licensor hereby grants to Licensee a worldwide,
non-exclusive, royalty-free right and license to the copyright and related
rights (including without limitation the right to use, copy, distribute,
display, demonstrate and make derivative works) in the computer software
program known as "Turbochrom" and the source code related thereto (the
"Software") as such exist as of the Closing Date and to the extent any
improvements or upgrades thereto are funded solely by Licensee pursuant to
the applicable Transition Agreement.

          Section 1.4.  Trademarks.  During the Term as set forth in Article
7, Licensor hereby grants to Licensee a worldwide, non-exclusive, royalty-
free right and license to the use the trademarks set forth on Schedule B
annexed hereto in the field of computer software with applications in liquid
and gas chromatography (the "Turbochrom Trademarks").

          Section 1.5.  Company Initials.  (a)  During the Term as set forth
in Article 7, Licensor hereby grants to Licensee a worldwide, non-exclusive,
royalty-free right and license to use the trademarks set forth on Schedule C
annexed hereto, which include "PE," the initials of Licensor (the "PE
Trademarks," together with the Turbochrom Trademarks, the "Trademarks," and
the Trademarks together with the Patents, Know-How and Software, the
"Licensed Property") in connection with the goods and services sold or
provided in connection with such trademarks as of the Effective Date.

          (b)  The parties acknowledge that, pursuant to the Purchase
Agreement, Licensee is acquiring an existing inventory of tangible materials,
including, without limitation, letterhead, invoices and other business forms
(the "Inventory") that bear the PE Trademarks.  The parties agree that
Licensee may continue to distribute or otherwise make use of such Inventory
in the ordinary course of business consistent with past practice, subject to
Licensee's obligations under Article 2 hereof.  Licensee also agrees that
while Licensee makes use of the Inventory pursuant to this Section 1.5,
Licensee shall ensure that any contract signed with a third party clearly and
plainly communicates to such party that it is doing business with Licensee
and not Licensor.  Licensee agrees that Licensee's employees and agents shall
not represent that they are or hold themselves to be affiliated with
Licensor.  Licensee agrees that it will take all necessary or desirable
actions to minimize potential confusion as to the source of its products viz-
a-vis Licensor.

          Article 2.  Trademark Protection.

          Section 2.1. Good Practice.  Licensee shall use the Trademarks in
good faith, in a dignified manner, and in accordance with good trademark and
industry practice wherever the Trademarks are used.  Unless approved by
Licensor, which approval shall not be unreasonably withheld, Licensee shall
refrain from using the Trademarks in combination with the trademark of any

bearing the Trademarks, any advertising or promotional materials related to
such products or any other advertising or promotional materials of Licensee.

          Section 2.2. Quality Standard.  The quality of (i) the products
offered by Licensee under the Trademarks and (ii) all advertising,
promotional and marketing materials with respect to the Trademarks shall

the Effective Date.  Licensee shall not do any act that brings Licensor or
the Trademarks into disrepute.

          Section 2.3.  Representative Samples.    Licensor has the right, at
reasonable intervals, to request representative samples of Licensee's
products and advertising, promotional and marketing materials to ensure that
appropriate standards with respect to quality are being met.

          Section 2.4.  Future Use of PE Trademarks.    Licensee agrees that,
after expiration or termination of the license grant in Section 1.5, it shall
not use the initials "PE" as a trademark or service mark in connection with
any of its current or future products or services or any related advertising,
marketing and promotions.  Licensee agrees that such prohibited "use" shall
include, without limitation, any display of the first two letters of the name
"Perkin" in such manner that highlights or otherwise calls specific or
separate attention to them apart from the "Perkin-Elmer" name as a whole.

          Article 3.  Reservation and Limitation of Rights.

property other than the Licensed Property, including any intellectual

          Article 4.  Ownership of Intellectual Property.

          Section 4.1.  Ownership by Licensor.  Licensee agrees that, as
between Licensor and Licensee, Licensor is the sole and exclusive owner of
all right, title and interest in and to the Licensed Property, subject to the
licensed rights granted to Licensee hereunder.  Licensee agrees not to
directly or indirectly question, attack, contest or in any other manner
impugn the validity and/or enforceability of the Licensed Property or
Licensor's rights therein, including without limitation, in any action in
which enforcement of a provision of this Agreement is sought; nor shall
Licensee willingly become a party adverse to Licensor in litigation in which
a third party contests the validity and/or enforceability of the Licensed
Property or Licensor's rights therein.

          Section 4.2.  Further Cooperation.  Licensee shall, during the Term
and after termination hereof, execute such documents as Licensor may
reasonably request from time to time to evidence and record with all
appropriate authorities that all ownership right, title and interest in and
to the Licensed Property reside in Licensor.

          Section 4.3.  Survival.  The provisions of this Article 4 shall
survive any termination of this Agreement.

          Article 5.  Maintenance.  Licensor agrees to take actions, pay fees
and execute  documents as reasonably necessary to (i) maintain legal
protection for any patents or registrations within the Licensed Property;
(ii) prosecute any applications within the Licensed Property; and (iii) seek
U.S. federal and foreign protection for all other Licensed Property (the
foregoing, "Maintenance Obligations").  Licensee shall cooperate with
Licensor as necessary to enable Licensor to fulfill its Maintenance
Obligations.  If Licensor chooses not to fulfill a Maintenance Obligation
with respect to any Licensed Property, Licensor shall notify Licensee
promptly of such decision and, in addition to Licensee's other remedies,
Licensee shall have the right, at Licensee's option, either (i) to perform
such Maintenance Obligations on Licensor's behalf and with Licensor's
cooperation, including the execution of all necessary documents by Licensor,
at Licensee's cost, or (ii) to have such Licensed Property assigned to
Licensee, at Licensee's cost, subject to a worldwide, non-exclusive, royalty-
free license back to Licensor.

          Article 6.  Approvals and Applicable Laws.

          Section 6.1.  Compliance.  Licensee shall, at its sole expense,
comply at all times with all applicable laws and regulations pertaining to
the use of the Licensed Property, including all laws governing the importing
and exporting of the applicable Licensed Property from or to any other nation

                                      -4-

<PAGE>

regulations in connection with its use and distribution of its products and
shall establish and maintain, and shall cause its employees, contractors,
consultants and agents to maintain a high standard of ethical business
practices in connection with the sale, use and distribution of its products.

          Section 6.2.  Notices.   Licensee agrees to include on all Licensed
Property all notices and legends required by applicable law or regulations to
preserve and protect the validity of the Licensed Property and Licensor's
rights therein, to the extent that Licensee is aware of the use of such
Licensed Property (in particular, on products).  Licensee shall not remove,
alter, cover or obfuscate any notices or other proprietary or restrictive
notice or legend placed or embedded by Licensor on or in the Licensed
Property or materials embodying any Licensed Property.

          Article 7.  Term.  The term of this Agreement ("Term") commences on
the Effective Date and lasts, unless termination occurs under Article 8, (i)
with respect to the license granted in Section 1.1,  until expiration of the
last patent listed on Schedule A; (ii) with respect to the license granted in
Section 1.2, in perpetuity; (iii) with respect to the license granted in
Section 1.3, in perpetuity;  (iv) with respect to the license granted in
Section 1.4, for two years; and (v) with respect to the license granted in
Section 1.5, for one year.  As each license expires, the provisions in this
Agreement relating to such license shall expire, but the remainder of the
Agreement shall remain in full force and effect.

          Article 8.  Material Breach and Termination.

          Section 8.1.  Material Breach by Licensee.  In the event that
Licensee materially breaches any of its obligations under this Agreement,
Licensor may, by written notice, require that Licensee take corrective
action.  Licensee shall immediately take whatever steps are necessary to
remedy the breach, at its sole cost and expense, or shall contest such breach
in writing to Licensor within 10 business days of receipt of notice thereof.
If Licensee does not (i) timely contest the notice of breach, (ii) remedy
such breach within 60 days of receipt of such notice or (iii) use its best
efforts within such 60-day period to cure such breach and make substantial
progress toward cure, Licensee shall immediately cease using any and all
Licensed Property affected by the breach until such breach is remedied.  If
Licensee timely contests the breach, or if after the 60-day period expires,
Licensee has not cured the breach or made substantial progress toward cure,
Licensor may apply to a court of competent jurisdiction for appropriate
relief.  If such court determines that a material breach of this Agreement
has occurred and has not been cured, or that Licensee has not made
substantial progress towards cure, or that such breach is not capable of
being cured in a reasonable amount of time, then Licensor shall be entitled
to all rights and remedies available at law or in equity, and Licensee shall
be deemed to have irrevocably and unconditionally consented to the entry of

                                      -5-

<PAGE>

an order by a court of competent jurisdiction granting an injunction against
further use of the Licensed Property in the manner that constituted the
material breach, but shall not be enjoined from non-breaching uses of the
Licensed Property.

          Section 8.2.  Default.  Either party may terminate this Agreement
at any time, upon written notice, if the other party makes an assignment for
the benefit of creditors, admits in writing its inability to pay debts as
they mature, has a trustee or receiver appointed for a substantial part of
its assets, or, to the extent enforceable under the U.S. Bankruptcy Code, has
instituted against it a proceeding in bankruptcy which is acquiesced in, is
not dismissed within 120 days, or results in an adjudication of bankruptcy.
If such an event occurs, the non-bankrupt party shall have the right, in
addition to its other rights and remedies, to suspend the bankrupt party's
rights regarding the Licensed Property while the bankrupt party attempts to
remedy the situation.

          Section 8.3.  Assignment.  The license granted in Section 1.5 shall
terminate immediately in the event of (i) a change of control, or sale of
substantially all the assets, of Licensee.  In addition, the license granted
in Section 1.5 shall terminate immediately upon the sale or transfer by
Licensee to any non-Affiliate (as defined in the Purchase Agreement) of any
product line to which the applicable trademarks relate.

          Section 8.4.  After Expiration/Termination.  Upon expiration of any
license under Article 1 or termination of this Agreement, Licensor and
Licensee agree to cooperate so as best to preserve the value of the
applicable Licensed Property.  Upon such expiration or termination, Licensee
agrees immediately to discontinue all use of the applicable Licensed
Property, and at Licensor's request, to destroy or return the same promptly
and certify that such action was taken.

          Article 9.  Representations and Warranties.

          Section 9.1.   Warranty by Licensor.   Licensor represents and
warrants to Licensee that, to Licensor's knowledge, except as set forth on
Schedule D hereto, (i) no third party is infringing, violating or
misappropriating any of the Licensed Property, and (ii) the Licensed Property
does not materially infringe or violate, or constitute a material
misappropriation of, any intellectual property of a third party.

          Section 9.2.  Limitations of Warranty.    Licensee acknowledges
that, with respect to this Agreement, Licensor makes no representation or
warranty whatsoever as to the value of the Licensed Property.  Except as
otherwise specified in this Article 9, there are no warranties, either
express or implied, respecting the Licensed Property, including without
limitation, implied warranties of merchantability or fitness for any

                                      -6-

<PAGE>

particular purpose.   Licensor makes no representation or warranties to
Licensee, either express or implied, nor assumes nor accepts any liability to
Licensee, with respect to the quality or sufficiency of any results to be
achieved by Licensee's use of the Licensed Property.  Licensee expressly
assumes all risks if any, associated therewith.

          Article 10.  Indemnification.

          Section 10.1.  By Licensee.  Licensee agrees to defend, indemnify,
and hold harmless Licensor and its directors, officers, employees and agents
("Licensor Parties") against all damages, costs, expenses, settlements,
judgments, fines, liabilities and fees (including attorneys' fees and
litigation costs and expenses) ("Damages") incurred by any Licensor Parties
based upon, arising out of or relating to any action, suit or proceeding
brought by third parties ("Action") as a result of a breach of this Agreement
by Licensee.

          Section 10.2.  By Licensor.  Licensor agrees to defend, indemnify,
and hold harmless Licensee and its directors, officers, employees and agents
("Licensee Parties") against all Damages incurred by any Licensee Parties
based upon, arising out of or relating to any Action as a result of a breach
of this Agreement, or breach of a representation and warranty in this
Agreement, by Licensor.

          Section 10.3.  Notification.  All claims for indemnification by a
Licensor Party or Licensee Party, as the case may be (an "Indemnified
Party"), hereunder shall be asserted and resolved as set forth in this
Section 10.3.  In the event that any written claim or demand for which
Licensor or Licensee, as the case may be (an "Indemnifying Party"), would be
liable to any Indemnified Party hereunder is asserted against or sought to be
collected from any Indemnified Party by a third party, such Indemnified Party
shall promptly notify the Indemnifying Party of such claim or demand and the
amount or the estimated amount thereof to the extent then feasible (which
estimate shall not be conclusive of the final amount of such claim or demand)
(the "Claim Notice").  The Indemnifying Party shall have 30 days from the
date of receipt of the Claim Notice (the "Notice Period") to notify the
Indemnified Party (i) whether or not the Indemnifying Party disputes the
liability of the Indemnifying Party to the Indemnified Party hereunder with
respect to such claim or demand and (ii) whether or not it desires to defend
the Indemnified Party against such claim or demand.  All costs and expenses
incurred by the Indemnifying Party in defending such claim or demand shall be
a liability of, and shall be paid by, the Indemnifying Party.  Except as
hereinafter provided, in the event that the Indemnifying Party notifies the
Indemnified Party within the Notice Period that it desires to defend the
Indemnified Party against such claim or demand, the Indemnifying Party shall
have the right to defend the Indemnified Party by appropriate proceedings and
shall have the sole power to direct and control such defense.  If any

                                      -7-

<PAGE>

Indemnified Party desires to participate in any such defense, it may do so at
its sole cost and expense.  The Indemnified Party shall not settle a claim or
demand without the consent of the Indemnifying Party.  The Indemnifying Party
shall not, without the prior written consent of the Indemnified Party,
settle, compromise or offer to settle or compromise any such claim or demand
on a basis which would result in the imposition of a consent order,
injunction or decree which would restrict the future activity or conduct of
the Indemnified Party or any subsidiary or affiliate thereof or if such
settlement or compromise does not include an unconditional release of the
Indemnified Party for any liability arising out of such claim or demand.  If
the Indemnifying Party elects not to defend the Indemnified Party against
such claim or demand, whether by not giving the Indemnified Party timely
notice as provided above or otherwise, then the amount of any such claim or
demand or, if the same be contested by the Indemnified Party, that portion
thereof as to which such defense is unsuccessful (and the reasonable costs
and expenses pertaining to such defense), shall be the liability of the
Indemnifying Party hereunder, subject to the limitations set forth in
Sections 10.3(a) and 10.3(b).  Licensor and Licensee shall each render to
each other such assistance as may reasonably be requested in order to insure
the proper and adequate defense of any such claim or proceeding.

          (a)  The indemnities provided in this Section 10.3 shall be the
sole and exclusive remedy of the Indemnified Party against the Indemnifying
Party at law or equity for any matter covered by Sections 10.1 and 10.2.

          (b)  The amount of any Damages for which indemnification is
provided under this Section 10.3 shall be computed net of any insurance
proceeds received by the Indemnified Party in connection with such Damages.
If the amount with respect to which any claim is made under this Section 10.3
(an "Indemnity Claim") gives rise to a currently realizable Tax Benefit (as
defined below) to the party making the claim, the indemnity payment shall be
reduced by the amount of the Tax Benefit available to the party making the
claim.  To the extent such Indemnity Claim does not give rise to a currently
realizable Tax Benefit, if the amount with respect to which any Indemnity
Claim is made gives rise to a subsequently realized Tax Benefit to the party
that made the claim, such party shall refund to the Indemnifying Party the
amount of such Tax Benefit when, as and if realized.  For the purposes of
this Agreement, any subsequently realized Tax Benefit shall be treated as
though it were a reduction in the amount of the initial Indemnity Claim, and
the liabilities of the parties shall be redetermined as though both occurred
at or prior to the time of the indemnity payment.  For purposes of this
Section 10.3(b), a "Tax Benefit" means an amount by which the tax liability
of the party (or group of corporations including the party) is reduced
(including, without limitation, by deduction, reduction of income by virtue
of increased tax basis or otherwise, entitlement to refund, credit or
otherwise) plus any related interest received from the relevant taxing
authority.  Where a party has other losses, deductions, credits or items

                                      -8-

<PAGE>

available to it, the Tax Benefit from any losses, deductions, credits or
items relating to the Indemnity Claim shall be deemed to be realized
proportionately with any other losses, deductions, credits or items.  For the
purposes of this Section 10.3(b), a Tax Benefit is "currently realizable" to
the extent it can be reasonably anticipated that such Tax Benefit will be
realized in the current taxable period or year or in any Tax Return with
respect thereto (including through a carryback to a prior taxable period) or
in any taxable period or year prior to the date of the Indemnity Claim.  In
the event that there should be a determination disallowing the Tax Benefit,
the Indemnifying Party shall be liable to refund to the Indemnified Party the
amount of any related reduction previously allowed or payments previously
made to the Indemnifying Party pursuant to this Section 10.3.  The amount of
the refunded reduction or payment shall be deemed a payment under this
Section 10.3 and thus shall be paid subject to any applicable reductions
under this Section 10.3.

          (c)  Each Indemnified Party shall be obligated in connection with
any claim for indemnification under this Section 10.3 to use all reasonable
efforts to mitigate Damages upon and after becoming aware of any event which
could reasonably be expected to give rise to such Damages.

          (d)  Notwithstanding anything to the contrary contained herein,
neither party hereto nor any affiliate of either of them shall be liable for
any consequential, punitive or special damages pursuant to this Agreement or
any of the agreements contemplated hereby.

          Article 11.  Confidentiality.

          Section 11.1.  Software/Know-How.   Licensee shall use commercially
reasonable  efforts, including executing all necessary contractual
provisions, to prevent third parties from modifying, altering, changing,
reproducing, reverse engineering, dissembling, decompiling, distributing or
copying the Software or Know-How or deriving any source code or algorithms
therefrom.

          Section 11.2.  Confidential Information.  In connection with this
Agreement,  Licensor and Licensee (each a "Disclosing Party") may each
disclose certain Confidential Information (as hereinafter defined) to the
other party (each a "Receiving Party"). "Confidential Information," subject
to the provisions of Section 11.4, shall mean (i) any information disclosed
after the Effective Date and designated in writing as confidential,
proprietary, or marked with words of like import; and (ii) any information
orally or visually conveyed, if the Disclosing Party provides specific
written notice that such oral or visual communication shall be deemed
Confidential Information and delivers such writing to the Receiving Party
within 10 days after the oral or visual conveyance.

          Section 11.3.  Restricted Disclosure.  Each of Licensor and
Licensee acknowledge the confidential and proprietary nature of the other
party's Confidential Information and agree that as the Receiving Party, it
shall use the same level of care it accords its own confidential information
(but in any event, no less than a reasonable standard of care) not to reveal
or disclose any Confidential Information for any purpose (except as permitted
by the following sentence) to any third party not a Receiving Party, nor use
any Confidential Information for any purpose other than as contemplated
hereby, in each case, without the prior written consent of the Disclosing
Party.  In the event that a Receiving Party wishes to disclose Confidential
Information to a third party (other than another Receiving Party), it may do
so only with the express written consent of the Disclosing Party or if the
third party is a reputable party and signs an agreement with the Receiving
Party that is appropriate under the circumstances and is reasonably
calculated to ensure the confidentiality of the applicable Confidential
Information.  Upon request, the Disclosing Party shall have the right to
review such agreements to ensure that the foregoing obligation is fulfulled.

          Section 11.4.  Exceptions.  Notwithstanding anything contained
herein to the contrary, Confidential Information shall not include
information which:

          (a)  at or prior to the time of disclosure by the Disclosing Party
     was known to or independently developed by the Receiving Party as
     evidenced by one or more documents, except to the extent unlawfully
     appropriated by the Receiving Party or third party;

          (b)  at or after the time of disclosure by the Disclosing Party
     becomes generally available to the public through no wrongful or
     negligent act or omission on the Receiving Party's part;

          (c)  is later developed by the Receiving Party independent of any
     Confidential Information it receives from the Disclosing Party:

          (d)  the Receiving Party receives from a third party free to make
     such disclosure without breach of any legal obligation; or

          (e)  is required to be disclosed pursuant to any statute,
     regulation, order, subpoena or document discovery request, provided that
     prior written notice of such disclosure is furnished to the Disclosing
     Party as soon as practicable in order to afford the Disclosing Party an
     opportunity to seek a protective order (it being agreed that if the
     Disclosing Party is unable to obtain or does not seek a protective order
     and the Receiving Party is legally compelled to disclose such
     information, disclosure of such information may be made without
     liability).

<PAGE>

          Section 11.5.  Injunctive Relief.  In view of the difficulties of
placing a monetary value on the Confidential Information, the Disclosing
Party may be entitled to a preliminary and final injunction without the
necessity of posting any bond or undertaking in connection therewith to
prevent any further breach of this Article 11 or further unauthorized use of
Confidential Information.  This remedy is separate and apart from any other
remedy the Disclosing Party may have.

          Section 11.6.  Remedial Measures.  Licensor or Licensee, as the
case may be, shall notify the Disclosing Party immediately upon discovery of
any prohibited use or disclosure of the Confidential Information, or any
other breach of this Article 11 by a Receiving Party, and shall fully
cooperate with the Disclosing Party to help the Disclosing Party regain
possession of the Confidential Information and prevent the further prohibited
use or disclosure of the Confidential Information.

          Section 11.7.  Term.  The term of this Article 11 shall commence on
the Effective Date and last five years, and shall survive any earlier
termination of this Agreement.

          Article 12.  Infringement.  Licensee agrees to notify Licensor
immediately after it becomes aware of any actual or threatened Infringement
of the Licensed Property by a third party.  Licensee may not file any Action
alleging Infringement of the Licensed Property without the prior written
approval of Licensor.  Licensor, in its absolute discretion, may file an
Action alleging Infringement of the Licensed Property without the consent of
Licensee.  Licensee agrees to cooperate with Licensor, at Licensor's request
and expense, in any such Action.  Licensor shall pay all costs and expenses
associated with and retain any and all such proceeds received in connection
with any such Action.

          Article 13.  Bankruptcy.  The licenses to the Patents, Know-How and
Software granted in Article 1 shall be deemed to be, for purposes of Section
365(n) of the U.S. Bankruptcy Code, licenses to rights in "intellectual
property" as defined in Section 101 of the Bankruptcy Code.  The parties
agree that Licensee shall retain and may fully exercise all of its rights and
elections under the Bankruptcy Code.  In the event that a bankruptcy
proceeding under the Bankruptcy Code is commenced by or against Licensor,
Licensee shall be entitled, at its option, to: (a) retain all of its rights
under this Agreement (including without limitation the rights and licenses
granted under Article 1 hereof) pursuant to Section 365(n) of the U.S.
Bankruptcy Code; or (b) receive a complete duplicate of, or complete access
to, all Patents, Know-How and Software licensed hereunder constituting
"intellectual property" under Section 101 of the Bankruptcy Code and all
embodiments thereof.  If such Patents, Know-How or Software is not already in
Licensee's possession, it shall be promptly delivered to Licensee upon
Licensee's written request (i) upon any such commencement of a bankruptcy

                                     -11-

<PAGE>

proceeding, unless Licensor elects to continue to perform all of its
obligations under this Agreement; or (ii) upon the rejection of this
Agreement by or on behalf of Licensor.

with any representations, warranties, covenants, or agreements contained
herein, and in any documents delivered or to be delivered pursuant to this
Agreement.  The waiver by any party hereto of a breach of any provision of
this Agreement shall not operate or be construed as a waiver of any
subsequent breach.

                           SELLER LICENSE AGREEMENT

          This SELLER LICENSE AGREEMENT ("Agreement") is effective as of May
28, 1999 ("Effective Date") from EG&G, Inc., a Massachusetts corporation
("Licensor") to The Perkin-Elmer Corporation, a New York corporation located
at 761 Main Avenue, Norwalk, CT 06859  ("Licensee").

          WHEREAS, pursuant to Section 1.2 of the Purchase Agreement between
Licensor and Licensee dated as of March 8, 1999 ("Purchase Agreement"),
Licensee has agreed to sell to Licensor the assets of the Analytical
Instruments Business (as defined therein), which pursuant to Section 1.2(a)
include certain Intellectual Property (as defined therein), subject to the
License Agreements (as defined therein);

          WHEREAS, pursuant to Section 4.8(b) of the Purchase Agreement, the
License Agreements include this Agreement, pursuant to which Licensor is
granting to Licensee a license to use the Intellectual Property (as defined
therein) set forth on Schedule 4.8(b) thereto and Exhibit A hereto; and

          WHEREAS, pursuant to Sections 5.2(d) and 5.3(e) of the Purchase
Agreement, Licensor and Licensee must execute and deliver this Agreement to
each other at or prior to the Closing Date (as defined therein):

          NOW, THEREFORE, in consideration of the premises and the mutual
promises and covenants contained herein and for other good and valuable
consideration (including that set forth in the Purchase Agreement), the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

          Article 1.  Grant of License.

          Section 1.1.  Patents.  During the Term as set forth in Article 7,
Licensor hereby grants to Licensee a worldwide, non-exclusive, royalty-free
right and license to make, have made, use, import, distribute and sell
products under the United States and foreign patents and patent applications,
invention disclosures and other intellectual property rights listed on
Schedule A annexed hereto (the "Patents"), subject to Licensee's non-
competition obligations under Section 8.6 of the Purchase Agreement.

          Section 1.2.  Know-How.  During the Term as set forth in Article 7,
Licensor hereby grants to Licensee a worldwide, non-exclusive, royalty-free
right and license to make, have made, use, import, distribute and sell
products using any and all trade secrets, know-how and technology related to
the Patents, that exist and are in Licensee's possession as of the Effective
Date and are not otherwise covered by the license grant in Section 1.1 (the

<PAGE>

"Know-How"), subject to Licensee's non-competition obligations under Section
8.6 of the Purchase Agreement and the applicable Transition Agreement.

          Section 1.3.  Company Name.  (a)  During the Term as set forth in
Article 7, Licensor hereby grants to Licensee a worldwide, non-exclusive,
royalty-free right and license to use the name "Perkin-Elmer" (the "Company
Name," together with the Patents and Know-How, the "Licensed Property")
solely as necessary to indicate the prior corporate ownership of the
Analytical Instruments Business by Licensee prior to the Effective Date, and
not in connection with sales of products by Licensee.

          (b)  The parties acknowledge that Licensee has an existing
inventory of tangible materials, including, without limitation, letterhead,
invoices and other business forms (the "Inventory") that bear the Company
Name.  The parties agree that Licensee may continue to distribute or other-
wise make use of such Inventory in the ordinary course of business consistent
with past practice, subject to Licensee's obligations under Article 2 hereof.
Licensee also agrees that while Licensee makes use of the Inventory pursuant
to this Section 1.3, Licensee shall ensure that any contract signed with a
third party clearly and plainly communicates to such party that it is doing
business with Licensee and not Licensor.  Licensee agrees that Licensee's
employees and agents shall not represent that they are or hold themselves to
be affiliated with Licensor.  Licensee agrees that it will take all necessary
or desirable actions to minimize potential confusion as to the source of its
products viz-a-vis Licensor.

          Article 2.  Company Name Protection.

          Section 2.1. Good Practice.  Licensee shall use the Company Name in
good faith, in a dignified manner, and in accordance with good trademark and
industry practice wherever the Company Name is used.  Unless approved by
Licensor, which approval shall not be unreasonably withheld, Licensee shall
refrain from using the Company Name in combination with the trademark of any
third party (i.e., other than Licensee) on the packaging of any products
bearing the Company Name, any advertising or promotional materials related to
such products or any other advertising or promotional materials of Licensee.

          Section 2.2. Quality Standard.  The quality of (i) the products
offered by Licensee under the Company Name; (ii) all advertising, promotional
and marketing materials with respect to the Company Name; and (iii) all
operations of the business bearing the Company Name shall operate with
quality standards at least as high as those of Licensee as of the Effective
Date.  Licensee shall not do any act that brings Licensor or the Company Name
into disrepute.

          Section 2.3.  Representative Samples.    Licensor has the right, at
reasonable intervals, to request representative samples of Licensee's

                                      -2-

<PAGE>

products and advertising, promotional and marketing materials to ensure that
appropriate standards with respect to quality are being met.

          Article 3.  Reservation and Limitation of Rights.

          Section 3.1.  Reservation to Licensor.  All rights not expressly
granted to Licensee in Article 1 are reserved to Licensor.  Licensee
disclaims any right to use the Licensed Property except in accordance with
the express grants in Article 1.  Licensee expressly agrees that its use of
the Licensed Property shall be consistent with all relevant terms of the
Purchase Agreement, including without limitation Section 8.6.

          Section 3.2.  No Other Property.  Licensee acknowledges that
Licensor has no obligation to make available to Licensee any intellectual
property other than the Licensed Property, including any intellectual
property similar or identical thereto or to provide Licensee with any
modifications,  updates, revisions, new developments or improvements to the
Licensed Property created or developed after the Effective Date.

          Article 4.  Ownership of Intellectual Property.

          Section 4.1.  Ownership by Licensor.  Licensee agrees that, as
between Licensor and Licensee, Licensor is the sole and exclusive owner of
all right, title and interest in and to the Licensed Property, subject to the
licensed rights granted to Licensee hereunder.  Licensee agrees not to
directly or indirectly question, attack, contest or in any other manner
impugn the validity and/or enforceability of the Licensed Property or
Licensor's rights therein, including without limitation, in any action in
which enforcement of a provision of this Agreement is sought; nor shall
Licensee willingly become a party adverse to Licensor in litigation in which
a third party contests the validity and/or enforceability of the Licensed
Property or Licensor's rights therein.

          Section 4.2.  Further Cooperation.  Licensee shall, during the Term
and after termination hereof, execute such documents as Licensor may
reasonably request from time to time to evidence and record with all
appropriate authorities that all ownership right, title and interest in and
to the Licensed Property reside in Licensor.

          Section 4.3.  Survival.  The provisions of this Article 3 shall
survive any termination of this Agreement.

          Article 5.  Maintenance.  Licensor agrees to take actions, pay fees
and execute  documents as reasonably necessary to (i) maintain legal
protection for any patents or registrations within the Licensed Property;
(ii) prosecute any applications within the Licensed Property; and (iii) seek
U.S. federal or foreign protection for all other Licensed Property (the

                                      -3-

<PAGE>

foregoing, "Maintenance Obligations").  Licensee shall cooperate with
Licensor as necessary to enable Licensor to fulfill its Maintenance
Obligations.  If Licensor chooses not to fulfill a Maintenance Obligation
with respect to any Licensed Property, Licensor shall notify Licensee
promptly of such decision and, in addition to Licensee's other remedies,
Licensee shall have the right, at Licensee's option, either (i) to perform
such Maintenance Obligations on Licensor's behalf and with Licensor's
cooperation, including the execution of all necessary documents by Licensor,
or (ii) to have such Licensed Property assigned to Licensee, at Licensee's
cost, subject to a worldwide, non-exclusive, royalty-free license back to
Licensor.

          Article 6.  Approvals and Applicable Laws.

          Section 6.1.  Compliance.  Licensee shall, at its sole expense,
comply at all times with all applicable laws and regulations pertaining to
the use of the Licensed Property, including all laws governing the importing
and exporting of the applicable Licensed Property from or to any other nation
or sovereignty.  Licensee shall comply with all applicable laws and
regulations in connection with its use and distribution of its products and
shall establish and maintain, and shall cause its employees, contractors,
consultants and agents to maintain a high standard of ethical business
practices in connection with the sale, use and distribution of its products.

          Section 6.2.  Notices.   Licensee agrees to include on all Licensed
Property all notices and legends required by applicable law or regulations to
preserve and protect the validity of the Licensed Property and Licensor's
rights therein, to the extent that Licensee is aware of the use of such
Licensed Property (in particular, on products).  Licensee shall not remove,
alter, cover or obfuscate any notices or other proprietary or restrictive
notice or legend placed or embedded by Licensor on or in the Licensed
Property or materials embodying any Licensed Property.

          Article 7.  Term.  The term of this Agreement ("Term") commences on
the Effective Date and lasts, unless termination occurs under Article 7, (i)
with respect to the license granted in Section 1.1, until expiration of the
last patent listed on Schedule A; (ii) with respect to the license granted in
Section 1.2, in perpetuity; and (iii) with respect to the license granted in
Section 1.3, one year.  As each license expires, the provisions in this
Agreement relating to such license shall expire, but the remainder of the
Agreement shall remain in full force and effect.

          Article 8.  Material Breach and Termination.

          Section 8.1.  Material Breach by Licensee.  In the event that
Licensee materially breaches any of its obligations under this Agreement,
Licensor may, by written notice, require that Licensee take corrective

                                      -4-

<PAGE>

action.  Licensee shall immediately take whatever steps are necessary to
remedy the breach, at its sole cost and expense, or shall contest such breach
in writing to Licensor within 10 business days of receipt of notice thereof.
If Licensee does not (i) timely contest the notice of breach, (ii) remedy
such breach within 60 days of receipt of such notice or (iii) use its best
efforts within such 60-day period to cure such breach and make substantial
progress toward cure, Licensee shall immediately cease using any and all
Licensed Property affected by the breach until such breach is remedied.  If
Licensee timely contests the breach, or if after the 60-day period expires,
Licensee has not cured the breach or made substantial progress toward cure,
Licensor may apply to a court of competent jurisdiction for appropriate
relief.  If such court determines that a material breach of this Agreement
has occurred and has not been cured, or that Licensee has not made
substantial progress towards cure, or that such breach is not capable of
being cured in a reasonable amount of time, then Licensor shall be entitled
to all rights and remedies available at law or in equity, and Licensee shall
be deemed to have irrevocably and unconditionally consented to the entry of
an order by a court of competent jurisdiction granting an injunction against
further use of the Licensed Property in the manner that constituted the
material breach, but shall not be enjoined from non-breaching uses of the
Licensed Property.

          Section 8.2.  Default.  Either party may terminate this Agreement
at any time, upon written notice, if the other party makes an assignment for
the benefit of creditors, admits in writing its inability to pay debts as
they mature, has a trustee or receiver appointed for a substantial part of
its assets, or, to the extent enforceable under the U.S. Bankruptcy Code, has
instituted against it a proceeding in bankruptcy which is acquiesced in, is
not dismissed within 120 days, or results in an adjudication of bankruptcy.
If such an event occurs, the non-bankrupt party shall have the right, in
addition to its other rights and remedies, to suspend the bankrupt party's
rights regarding the Licensed Property while the bankrupt party attempts to
remedy the situation.

          Section 8.3.  Assignment.  The license granted in Section 1.3 shall
terminate immediately in the event of a change of control, or sale of
substantially all the assets, of Licensee.

          Section 8.4.  After Expiration/Termination.  Upon expiration of any
license under Article 1 or termination of this Agreement, Licensor and
Licensee agree to cooperate so as best to preserve the value of the
applicable Licensed Property.  Upon such expiration or termination, Licensee
agrees immediately to discontinue all use of the applicable Licensed
Property, and at Licensor's request, to destroy or return the same promptly
and certify that such action was taken.

          Article 9.  Warranty Disclaimer.   Licensee acknowledges that, with
respect to this agreement, Licensor makes no representation or warranty
whatsoever, as to ownership, value or non-infringement of the Licensed
Property.  The Licensed Property is hereby licensed to Licensee on an "as is"
basis.  Except as otherwise specified in this Article 9, there are no
warranties, either express or implied, respecting the Licensed Property,
including without limitation implied warranties of merchantability or fitness
for any particular purpose.  Licensor makes no representation or warranties
to Licensee, either express or implied, nor assumes nor accepts any liability
to Licensee, with respect to the quality or sufficiency of any results to be
achieved by Licensee's use of the Licensed Property.  Licensee expressly
assumes all risks if any, associated therewith.

          Article 10..  Indemnification.

          Section 10.1.  By Licensee.  Licensee agrees to defend, indemnify,
and hold harmless Licensor and its directors, officers, employees and agents
("Licensor Parties") against all damages, costs, expenses, settlements,
judgments, fines, liabilities and fees (including attorneys' fees and
litigation costs and expenses) ("Damages") incurred by any Licensor Parties
based upon, arising out of or relating to any action, suit or proceeding
brought by third parties ("Action") as a result of a breach of this Agreement
by Licensee.

          Section 10.2.  By Licensor.  Licensor agrees to defend, indemnify,
and hold harmless Licensee and its directors, officers, employees and agents
("Licensee Parties") against all Damages incurred by any Licensee Parties
based upon, arising out of or relating to any Action as a result of a breach
of this Agreement by Licensor.

          Section 10.3.  Notification.  All claims for indemnification by a
Licensor Party or Licensee Party, as the case may be (an "Indemnified
Party"), hereunder shall be asserted and resolved as set forth in this
Section 10.3.  In the event that any written claim or demand for which
Licensor or Licensee, as the case may be (an "Indemnifying Party"), would be
liable to any Indemnified Party hereunder is asserted against or sought to be
collected from any Indemnified Party by a third party, such Indemnified Party
shall promptly notify the Indemnifying Party of such claim or demand and the
amount or the estimated amount thereof to the extent then feasible (which
estimate shall not be conclusive of the final amount of such claim or demand)
(the "Claim Notice").  The Indemnifying Party shall have 30 days from the
date of receipt of the Claim Notice (the "Notice Period") to notify the
Indemnified Party (i) whether or not the Indemnifying Party disputes the
liability of the Indemnifying Party to the Indemnified Party hereunder with
respect to such claim or demand and (ii) whether or not it desires to defend
the Indemnified Party against such claim or demand.  All costs and expenses
incurred by the Indemnifying Party in defending such claim or demand shall be

                                      -6-

<PAGE>

a liability of, and shall be paid by, the Indemnifying Party.  Except as
hereinafter provided, in the event that the Indemnifying Party notifies the
Indemnified Party within the Notice Period that it desires to defend the
Indemnified Party against such claim or demand, the Indemnifying Party shall
have the right to defend the Indemnified Party by appropriate proceedings and
shall have the sole power to direct and control such defense.  If any
Indemnified Party desires to participate in any such defense, it may do so at
its sole cost and expense.  The Indemnified Party shall not settle a claim or
demand without the consent of the Indemnifying Party.  The Indemnifying Party
shall not, without the prior written consent of the Indemnified Party,
settle, compromise or offer to settle or compromise any such claim or demand
on a basis which would result in the imposition of a consent order,
injunction or decree which would restrict the future activity or conduct of
the Indemnified Party or any subsidiary or affiliate thereof or if such
settlement or compromise does not include an unconditional release of the
Indemnified Party for any liability arising out of such claim or demand.  If
the Indemnifying Party elects not to defend the Indemnified Party against
such claim or demand, whether by not giving the Indemnified Party timely
notice as provided above or otherwise, then the amount of any such claim or
demand or, if the same be contested by the Indemnified Party, that portion
thereof as to which such defense is unsuccessful (and the reasonable costs
and expenses pertaining to such defense), shall be the liability of the
Indemnifying Party hereunder, subject to the limitations set forth in
Sections 10.3(a) and 10.3(b).  Licensor and Licensee shall each render to
each other such assistance as may reasonably be requested in order to insure
the proper and adequate defense of any such claim or proceeding.

          (a)  The indemnities provided in this Section 10.3 shall be the
sole and exclusive remedy of the Indemnified Party against the Indemnifying
Party at law or equity for any matter covered by Sections 10.1 and 10.2.

          (b)  The amount of any Damages for which indemnification is
provided under this Section 10.3 shall be computed net of any insurance
proceeds received by the Indemnified Party in connection with such Damages.
If the amount with respect to which any claim is made under this Section 10.3
(an "Indemnity Claim") gives rise to a currently realizable Tax Benefit (as
defined below) to the party making the claim, the indemnity payment shall be
reduced by the amount of the Tax Benefit available to the party making the
claim.  To the extent such Indemnity Claim does not give rise to a currently
realizable Tax Benefit, if the amount with respect to which any Indemnity
Claim is made gives rise to a subsequently realized Tax Benefit to the party
that made the claim, such party shall refund to the Indemnifying Party the
amount of such Tax Benefit when, as and if realized.  For the purposes of
this Agreement, any subsequently realized Tax Benefit shall be treated as
though it were a reduction in the amount of the initial Indemnity Claim, and
the liabilities of the parties shall be redetermined as though both occurred
at or prior to the time of the indemnity payment.  For purposes of this

                                      -7-

<PAGE>

Section 10.3(b), a "Tax Benefit" means an amount by which the tax liability
of the party (or group of corporations including the party) is reduced
(including, without limitation, by deduction, reduction of income by virtue
of increased tax basis or otherwise, entitlement to refund, credit or
otherwise) plus any related interest received from the relevant taxing
authority.  Where a party has other losses, deductions, credits or items
available to it, the Tax Benefit from any losses, deductions, credits or
items relating to the Indemnity Claim shall be deemed to be realized
proportionately with any other losses, deductions, credits or items.  For the
purposes of this Section 10.3(b), a Tax Benefit is "currently realizable" to
the extent it can be reasonably anticipated that such Tax Benefit will be
realized in the current taxable period or year or in any Tax Return with
respect thereto (including through a carryback to a prior taxable period) or
in any taxable period or year prior to the date of the Indemnity Claim.  In
the event that there should be a determination disallowing the Tax Benefit,
the Indemnifying Party shall be liable to refund to the Indemnified Party the
amount of any related reduction previously allowed or payments previously
made to the Indemnifying Party pursuant to this Section 10.3.  The amount of
the refunded reduction or payment shall be deemed a payment under this
Section 10.3 and thus shall be paid subject to any applicable reductions
under this Section 10.3.

          (c)  Each Indemnified Party shall be obligated in connection with
any claim for indemnification under this Section 10.3 to use all reasonable
efforts to mitigate Damages upon and after becoming aware of any event which
could reasonably be expected to give rise to such Damages.

          (d)  Notwithstanding anything to the contrary contained herein,
neither party hereto nor any affiliate of either of them shall be liable for
any consequential, punitive or special damages pursuant to this Agreement or
any of the agreements contemplated hereby.

          Article 11.  Confidentiality.

          Section 11.1.  Know-How.   Licensee shall use commercially
reasonable efforts, including executing all necessary contractual provisions,
to prevent third parties from modifying, altering, changing, reproducing,
reverse engineering, dissembling, decompiling, distributing or copying the
Know-How or deriving any source code or algorithms therefrom.

          Section 11.2.  Confidential Information.  In connection with this
Agreement,  Licensor and Licensee (each a "Disclosing Party") may each
disclose certain Confidential Information (as hereinafter defined) to the
other party (each a "Receiving Party"). "Confidential Information," subject
to the provisions of Section 11.4, shall mean (i) any information disclosed
after the Effective Date and designated in writing as confidential,
proprietary, or marked with words of like import; and (ii) any information

                                      -8-

<PAGE>

orally or visually conveyed, if the Disclosing Party provides specific
written notice that such oral or visual communication shall be deemed
Confidential Information and delivers such writing to the Receiving Party
within 10 days after the oral or visual conveyance.

          Section 11.3.  Restricted Disclosure.  Each of Licensor and
Licensee acknowledge the confidential and proprietary nature of the other
party's Confidential Information and agree that as the Receiving Party, it
shall use the same level of care it accords its own confidential information
(but in any event, no less than a reasonable standard of care) not to reveal
or disclose any Confidential Information for any purpose (except as permitted
by the following sentence) to any third party not a Receiving Party, nor use
any Confidential Information for any purpose other than as contemplated
hereby, in each case, without the prior written consent of the Disclosing
Party.  In the event that a Receiving Party wishes to disclose Confidential
Information to a third party (other than another Receiving Party), it may do
so only with the express written consent of the Disclosing Party or if the
third party is a reputable party and signs an agreement with the Receiving
Party that is appropriate under the circumstances and is reasonably
calculated to ensure the confidentiality of the applicable Confidential
Information.  Upon request, the Disclosing Party shall have the right to
review such agreements to ensure that the foregoing obligation is fulfilled.

          Section 11.4.  Exceptions.  Notwithstanding anything contained
herein to the contrary, Confidential Information shall not include
information which:

          (a)  at or prior to the time of disclosure by the Disclosing Party
     was known to or independently developed by the Receiving Party as
     evidenced by one or more documents, except to the extent unlawfully
     appropriated by the Receiving Party or third party;

          (b)  at or after the time of disclosure by the Disclosing Party
     becomes generally available to the public through no wrongful or
     negligent act or omission on the Receiving Party's part;

          (c)  is later developed by the Receiving Party independent of any
     Confidential Information it receives from the Disclosing Party:

          (d)  the Receiving Party receives from a third party free to make
     such disclosure without breach of any legal obligation; or

          (e)  is required to be disclosed pursuant to any statute,
     regulation, order, subpoena or document discovery request, provided that
     prior written notice of such disclosure is furnished to the Disclosing
     Party as soon as practicable in order to afford the Disclosing Party an
     opportunity to seek a protective order (it being agreed that if the

                                      -9-

<PAGE>

     Disclosing Party is unable to obtain or does not seek a protective order
     and the Receiving Party is legally compelled to disclose such
     information, disclosure of such information may be made without
     liability).

          Section 11.5.  Injunctive Relief.  In view of the difficulties of
placing a monetary value on the Confidential Information, the Disclosing
Party may be entitled to a preliminary and final injunction without the
necessity of posting any bond or undertaking in connection therewith to
prevent any further breach of this Article 11 or further unauthorized use of
Confidential Information.  This remedy is separate and apart from any other
remedy the Disclosing Party may have.

          Section 11.6.  Remedial Measures.  Licensor or Licensee, as the
case may be, shall notify the Disclosing Party immediately upon discovery of
any prohibited use or disclosure of the Confidential Information, or any
other breach of this Article 11 by a Receiving Party, and shall fully
cooperate with the Disclosing Party to help the Disclosing Party regain
possession of the Confidential Information and prevent the further prohibited
use or disclosure of the Confidential Information.

          Section 11.7.  Term.  The term of this Article 11 shall commence on
the Effective Date and last five years, and shall survive any earlier
termination of this Agreement.

          Article 12.  Infringement.  Licensee agrees to notify Licensor
immediately after it becomes aware of any actual or threatened Infringement
of the Licensed Property by a third party.  Licensee may not file any Action
alleging Infringement of the Licensed Property without the prior written
approval of Licensor.  Licensor, in its absolute discretion, may file an
Action alleging Infringement of the Licensed Property without the consent of
Licensee.  Licensee agrees to cooperate with Licensor, at Licensor's request
and expense, in any such Action.  Licensor shall pay all costs and expenses
associated with and retain any and all such proceeds received in connection
with any such Action.

          Article 13.  Bankruptcy.  The licenses to the Patents and Know-How
granted in Article 1 shall be deemed to be, for purposes of Section 365(n) of
the U.S. Bankruptcy Code, licenses to rights in "intellectual property" as
defined in Section 101 of the Bankruptcy Code.  The parties agree that
Licensee shall retain and may fully exercise all of its rights and elections
under the Bankruptcy Code.  In the event that a bankruptcy proceeding under
the Bankruptcy Code is commenced by or against Licensor, Licensee shall be
entitled, at its option, to: (a) retain all of its rights under this
Agreement (including without limitation the rights and licenses granted under
Article 1 hereof) pursuant to Section 365(n) of the U.S. Bankruptcy Code; or
(b) receive a complete duplicate of, or complete access to, all Patents and

                                     -10-

<PAGE>

Know-How licensed hereunder constituting "intellectual property" under
Section 101 of the Bankruptcy Code and all embodiments thereof.  If such
Patents or Know-How are not already in Licensee's possession, it shall be
promptly delivered to Licensee upon Licensee's written request (i) upon any
such commencement of a bankruptcy proceeding, unless Licensor elects to
continue to perform all of its obligations under this Agreement; or (ii) upon
the rejection of this Agreement by or on behalf of Licensor.

          Article 14..  Miscellaneous.

          Section 14.1. Notices.  All notices, requests, demands and other

          Section 14.2.   Entire Agreement.  This Agreement (including the
Exhibits and Schedules hereto) constitutes the entire agreement between the
parties hereto and supersedes all prior agreements and understandings, oral
and written, between the parties hereto with respect to the subject matter
hereof.

          Section 14.3.   Binding Effects; Benefit.  This Agreement shall
inure to the benefit of and be binding upon the parties hereto and their
respective successors and assigns.  Nothing in this Agreement, expressed or
implied, is intended to confer on any Person other than the parties hereto or
their respective successors and assigns, any rights, remedies, obligations or
liabilities under or by reason of this Agreement.

          Section 14.4.   Assignments and Sublicenses.  (a)  This Agreement,
or any portion thereof or license therein, may not be assigned or sublicensed
by either party to a non-Affiliate (as defined in the Purchase Agreement),
either directly or indirectly, without the prior written consent of the
other; such consent not to be withheld unreasonably; provided that nothing
herein shall restrict such assignment, if any, by Licensee of its rights and
obligations under this Agreement as may be necessary to implement the
transactions relating to Celera Genomics Corporation publicly announced by
Licensee on September 23, 1998.  Any attempted assignment by either party not
in accordance with this Section 14.4 shall be considered null and void ab
initio.

          (b)  Notwithstanding Section 14.4(a), Licensee may sublicense the
licenses granted in Sections 1.1 and 1.2 to the extent necessary for the
distributors and/or end users of Licensee's products to enjoy the benefits
thereof; however, Licensee shall not sublicense these licenses to third
parties for the independent manufacture, distribution, sale and/or use of
products under the Patents or Know-How.

          (c)  In the event of any permitted assignment, (i) this Agreement
shall be binding upon the successors and assigns of any assigning party; and
(ii) all reference herein to Licensor or Licensee shall mean both Licensor
and Licensee and their respective assignees, and the assignees shall not be
entitled to assign further this Agreement or sublicense rights governed
hereby without the prior written consent of the other party.

          Section 14.5.   Amendment; Waiver.  This Agreement, including this
Section,  may be amended, supplemented or otherwise modified only by a
written instrument executed by the parties hereto.  No waiver by either party
of any of the provisions hereof shall be effective unless explicitly set
forth in writing and executed by the party so waiving.  Except as provided in
the preceding sentence, no action taken pursuant to this Agreement, including
without limitation, any investigation by or on behalf of any party, shall be
deemed to constitute a waiver by the party taking such action of compliance

                                     -12-

<PAGE>

with any representations, warranties, covenants, or agreements contained
herein, and in any documents delivered or to be delivered pursuant to this
Agreement.  The waiver by any party hereto of a breach of any provision of
this Agreement shall not operate or be construed as a waiver of any
subsequent breach.

          Section 14.6.   Governing Law; Jurisdiction and Service of Process.
This Agreement shall be governed by, and construed in accordance with, the
laws of the State of New York.  Any suit, action or proceeding against any
party with respect to this Agreement may be brought in a court of the United
States sitting in the City of New York in the State of New York or in the
Commonwealth of Massachusetts or, if jurisdiction is lacking in such a court,
in a court of record in the State of New York or the Commonwealth of
Massachusetts, and each party hereto hereby irrevocably waives, to the
fullest extent permitted by law, any objection that it may have, whether now
or in the future, to the laying of venue in, or to the jurisdiction of, any
and each of such courts for the purpose of any such suit, action or
proceeding and further waives any claim that any such suit, action or
proceeding has been brought in an inconvenient forum, and each hereby submits
to such jurisdiction.

          Section 14.7.  Further Assurances.  Licensor and Licensee agree to
execute such further documentation and perform such further actions,
including the recordation of such documentation with appropriate authorities,
as may be reasonably requested by the other party hereto to evidence and

          Section 14.8.  Section Headings; Table of Contents.  The section
headings contained in this Agreement and the table of contents to this
Agreement are for reference purposes only and shall not affect the meaning or
interpretation of this Agreement.

          Section 14.9.  Severability.  If any provision of this Agreement
shall be declared by any court of competent jurisdiction to be illegal, void
or unenforceable, all other provisions of this Agreement shall not be
affected and shall remain in full force and effect.

          Section 14.10.  Counterparts.  This Agreement may be executed in
any number of counterparts, each of which shall be deemed to be an original
and all of which together shall be deemed to be one and the same instrument.

        ARTICLE III.  NATURE OF SERVICES AND CHARGES; BILLING; RECORDS

that the Services represent a continuation of the services provided to the
Analytical Instruments Business conducted by the PE Group(or its
predecessors) prior to the Closing Date, except to the extent the parties
otherwise have agreed. If, following the Agreement Date, the parties

inadvertently omitted from the Services hereunder, then, at EG&G's request,
the parties shall negotiate in good faith to attempt to agree to the terms
and conditions upon which such services can be added to this Agreement, it
being agreed that the charges for such services should be determined on a

and indirect costs, without provision for profit, on a basis consistent with
the methodology used in the preparation of the 1999 Budget (as defined in the
Purchase Agreement).

          3.2  Provision of Services.  (a)  Each Provider and each Recipient

for each Provider or Recipient in the PE Group, and EG&G will provide PE with
a list of the Contact Person for each Provider or Recipient in the EG&G

                                      -5-

Group.  Each Provider shall promptly advise any Recipient to which such
Provider provides Services of any change in the identity of its Contact
Person. Each party may treat an act of the other party's Contact Person as
being authorized by such other party without further inquiry.

          (b)  Except to the extent, if any, otherwise expressly provided
herein or in the Exhibits, each Provider shall provide the Services in
substantially the same manner, at substantially the same utilization levels
and with the same degree of care, diligence and priority as existed with
respect to the provision of such Services prior to the Closing Date.

          (c)  No Provider shall be required to provide any Recipient with
extraordinary levels of Services, special studies, training or the like or
the advantage of systems, equipment, facilities, training or improvements
procured, obtained or made after the Closing Date. Notwithstanding the
foregoing, each Provider shall use reasonable efforts to cooperate with and
assist, at such Recipient's expense, any Alternate Provider or any Recipient
in connection with the transfer of any Services from such Provider to such
Alternate Provider or such Recipient (as requested by such Recipient).

          (d)  In connection with the provision of Services by any Provider,
each Recipient to which such Services are being provided shall (i) maintain
all equipment, software and operational features in such fashion as is
adequate to permit the provision of Services by such Provider, (ii) comply
with any reasonable instructions of such Provider that are necessary or
appropriate for such Provider to adequately provide the Services, including
instructions regarding any contractual maintenance obligations, (iii) comply
with all applicable standards and procedures applicable to the Facilities and
any Service Location and (iv) promptly report any operational or system
problems to such Provider.

          (e)  No Provider shall be in default of its obligations hereunder
for any delays or failure in performance resulting from any cause or
circumstance beyond the reasonable control of such Provider, provided that
such Provider exercises commercially reasonable efforts to perform its
obligations in a timely manner.  If any such occurrence prevents any Provider
from providing any of the Services, such Provider shall cooperate with the
Recipient to which such Services are being provided in obtaining, at such
Recipient's sole expense, an alternative source for the affected Services,
and such Recipient shall be released from any payment obligation to such
Provider in respect of such Services (other than payments with respect to
obligations of such Provider to unaffiliated third parties) during the period
of such force majeure.

          3.3  Compensation.  (a)  The compensation for each Service provided
hereunder during the Term shall be as set forth in Exhibit A.

duty, export or import fee, sales tax, use tax, service tax or other tax or
charge imposed by any government or government authority on any Provider or
and Recipient with respect to the Services provided by such Recipient to such
Provider or the performance of this Agreement.

          (c)  Amounts payable pursuant to paragraph (a) of this Section 3.03
in respect of out of pocket costs incurred by any Provider in the performance
of Services hereunder shall be periodically adjusted for variances from the
amounts therefor reflected in Exhibit A, as well as out of pocket costs for
which no provision is made in Exhibit A.

          (d)  In addition to any amounts payable pursuant to the foregoing
provisions of this Section 3.03, each Recipient shall be solely responsible
for any increased costs arising in connection with obtaining any consents of
third parties required for the provision of Services hereunder.

          3.4  Terms of Payment.  (a)  Each Provider shall invoice the each
Recipient to which it provides Services monthly in arrears for the Services
provided under this Agreement, in such detail as the recipient may reasonably
request.  Payment shall be made by each Recipient with respect to all
uncontested amounts within 30 days following receipt of any invoice. Any
payments not made within such 30-day period which are later determined to be
due and payable thereafter shall bear interest at a rate equal to the 30-day
commercial paper rate for high-grade unsecured notes sold through dealers in
the United States of America by major corporations as listed from time to
time in the Money Rates table of The Wall Street Journal, but in no event to
exceed the highest rate of interest permitted by applicable law, calculated
from the date such payment was due until the date payment is received by the
such Provider.
          (b)  All amounts for Services rendered pursuant to this Agreement
shall be billed and paid in the currency in which the rate for such Services
is quoted herein or in the Exhibits.

          3.5  Records.  Each Provider will preserve all records supporting
the amounts charged to any Recipient pursuant to this Agreement for a period
of 6 years following the invoicing of such amounts. Thereafter, no Provider
shall not destroy or dispose of such records without giving notice to the
Recipient to which such records relate of such pending disposal and offering
such Recipient the right to obtain and retain such records at its own
expense. In the event such Recipient has not obtained such records within 30
days following the receipt of notice from any Provider, such Provider may
proceed to destroy or dispose of such records without any liability.  Subject
to any disclosure, copying or other limitations imposed by applicable law and
to any privileges (including the attorney-client privilege), each Provider
shall (a) at its own expense afford any Recipient to which such records
relate and its representatives reasonable access during normal business hours

                                      -7-

<PAGE>

upon reasonable prior notice to all such records and (b) at such Recipient's
expense provide copies of such records as such Recipient reasonably may
request for any proper purpose (including in connection with any judicial,
administrative, tax, audit or arbitration proceeding).

             ARTICLE IV.  RIGHTS IN, AND CONFIDENTIALITY OF, DATA

          4.1  General. Each party acknowledges that all information in any

          4.2  Reservation of Rights; Access. All rights to confidential,
proprietary and trade-sensitive information communicated hereunder by one
party or its Affiliates to the other party or its Affiliates are reserved by
the disclosing party and its Affiliates. The party receiving such disclosure

information to benefit itself or its Affiliates or to damage the disclosing
party or its Affiliates unless and until expressly authorized in writing to
do so by the disclosing party, or unless otherwise expressly permitted

and any required consents of third parties, each party hereby grants a right
to the other party, solely in connection with the provision of Services
hereunder, to have access to and use any hardware, software and documentation
owned by, leased by or licensed to such party that is necessary for the
provision of such Services. Each party shall use all reasonable efforts, at
such Recipient's sole expense, to obtain all consents or approvals necessary
in connection with such access and use.

          4.3  Duplication and Retention. All written data disclosed
hereunder is the property of the disclosing party and is not to be copied or
reproduced without the express written consent of the disclosing party except
as may be required for the performance of this Agreement; copies so made,

disclosing party's election, except for copies that the receiving party is
required to retain to comply with its legal obligations.  At the sole option
of the disclosing party, the receiving party shall provide the disclosing
party with a written statement duly signed by an authorized officer of the

Article IV, neither party shall be liable for any disclosure or use of any
knowledge contained in any information or data disclosed or communicated by
the other party hereunder:

          (a)  if such knowledge is publicly available or becomes publicly
     available other than as a result of a breach of this Agreement;

          (b)  if such knowledge is thereafter lawfully obtained by the
     receiving party from a third party without an obligation of
     confidentiality to the disclosing party;

          (c)  if such knowledge is known to the receiving party prior to
     such disclosure or is independently developed by the receiving party
     subsequent to its disclosure; or

          (d)  if it is required to be disclosed pursuant to legal demand,
     order or process of a competent court of law, governmental body,
     self-regulatory organization, regulated securities exchange or any body
     that is responsible for establishing and enforcing professional codes
     and standards ("Governmental Authorities"); provided that in these
     circumstances the receiving party shall have first provided the
     disclosing party with prompt written notice of such required disclosure
     and the receiving party shall cooperate with and assist the disclosing
     party, at the disclosing party's expense, in seeking a protective order
     or other similar assurance from such Governmental Authorities with
     respect to the confidentiality of the information required to be
     disclosed.

party and such other party's officers, directors, employees, shareholders and

fees and expenses) arising from the gross negligence or willful misconduct of
the Indemnifying Party or its employees, agents or other representatives

the other party for any claims, losses, damages, judgments, costs or expenses

indirect, special, incidental or consequential damages, including lost
profits or savings, whether or not such damages are foreseeable, or for any
third party claims relating to the Services or such Provider's performance
under this Agreement, unless due to willful misconduct or gross negligence.


                       ARTICLE VII.  DISPUTE RESOLUTION

          7.1  Negotiation.  (a)  In the event of a controversy, dispute or
claim arising out of, or in connection with, or in relation to the
interpretation, performance, nonperformance, validity or breach of this
Agreement or otherwise arising out of, or in any way related to this
Agreement or the transactions contemplated  hereby, including any claim based
on contract, tort, statute or constitution (collectively, "Agreement
Disputes"), the Contact Persons of the parties shall negotiate in good faith
for 30 days to settle such Agreement Dispute, provided such reasonable period
shall not, unless otherwise agreed by the parties in writing, exceed 30 days
from the time the parties began such negotiations.

          (b)  Each Provider and each Recipient shall appoint a person (a
"Supervisory Contact Person") to act as its representative to attempt to
resolve, prior to arbitration in accordance with Section 7.02, any Agreement

                                     -10-

<PAGE>

faith for a reasonable period of time to settle such Agreement Dispute,
provided such reasonable period shall not, unless otherwise agreed by the
parties in writing, exceed 20 days from the time of referral of such
Agreement Dispute to the Supervisory Contact Persons.

          (c)  In the event of any arbitration in accordance with Section
7.02, the parties shall not assert the defenses of statute of limitations and
laches arising for the period beginning after the date the parties began
negotiations hereunder, and any contractual time period or deadline under
this Agreement to which such Agreement Dispute relates shall not be deemed to
have passed until such Agreement Dispute has been resolved.

          7.2  Arbitration.  If the Supervisory Contact Persons are unable to
settle an Agreement Dispute (and, in any event, unless otherwise agreed in
writing by the parties, after 60 days have elapsed from the time the parties
began negotiations), such Agreement Dispute shall be determined, at the
request of a party, by arbitration conducted in a jurisdiction consistent
with Section 9.18 of the Purchase Agreement, before and in accordance with
the then-existing Rules of Arbitration of the International Chamber of
Commerce (the "International Rules").  In any dispute between the parties,
the number of arbitrators shall be three.  Any judgment or award rendered by
the arbitrators shall be final, binding and non-appealable (except on grounds
specified in 9 U.S.C. Section 10(a), as in effect on the Agreement Date).  If
the parties are unable to agree on the arbitrators, the arbitrators shall be
selected in accordance with the International Rules.  Any controversy
concerning whether an Agreement Dispute is an arbitrable Agreement Dispute,
whether arbitration has been waived, whether an assignee of this Agreement is
bound to arbitrate, or as to the interpretation or enforceability of this
Article VII shall be determined by the arbitrators.  In resolving any
dispute, the parties intend that the arbitrators apply the substantive laws
of the State of New York.  The parties intend that the provisions to
arbitrate set forth in this Section 7.02 be valid, enforceable  and
irrevocable.  The undersigned agree to comply with any award in any such
arbitration proceedings that has become  final in accordance with the
International Rules and agree to enforcement of or entry of judgment upon
such award, by any court of competent jurisdiction.  The arbitrators shall be
entitled, if  appropriate, to award any remedy in such proceedings, including
monetary damages, specific performance and all other forms of legal and
equitable relief; provided, however, the arbitrators shall not be entitled to
award punitive damages.  Without limiting the provisions of the International
