of fully paid and nonassessable common shares of Guarantor, par value U.S.

1/10,000) of the Daily Per Share Prices for the five consecutive trading days

and each Share owned by Guarantor, Parent, Merger Sub or any direct or
indirect, wholly-owned subsidiary of the Company or Guarantor immediately
prior to the Effective Time shall, by virtue of the Merger and without any

          (c)  Stock Options; Employee Stock Purchase Plan.  At the Effective

          (d)  Capital Stock of Merger Sub.  Each share of common stock,
$0.01 par value per share, of Merger Sub issued and outstanding immediately

per share, of the Surviving Corporation.

          (e)  Adjustments to Exchange Ratio etc.  If, during the period
between the date of this Agreement and the Effective Time, any change in the
outstanding shares of capital stock of Guarantor or the Company shall occur,
including by reason of any reclassification, recapitalization, stock split or
combination, exchange or readjustment of shares, or any stock dividend
thereon with a record date during such period, the Exchange Ratio, Floor
Price, the Merger Consideration and any other amounts payable pursuant to the
Merger or otherwise pursuant to this Agreement shall be appropriately
adjusted.

          (f)  Fractional Shares.  No certificates or scrip representing less
than one Guarantor Common Share shall be issued in exchange for Shares upon
the surrender for exchange of a certificate which immediately prior to the
Effective Time represented outstanding Shares (the "Certificates").  In lieu
of any such fractional share, each holder of Shares who would otherwise have
been entitled to a fraction of a Guarantor Common Share upon surrender of
Certificates for exchange shall be paid upon such surrender (and after taking
into account all certificates surrendered by such holder) cash (without
interest) in an amount equal to such fraction multiplied by the Average Share
Price.

          Section 1.07  Exchange of Shares.  (a)  Exchange Agent.  Parent
shall cause to be supplied to or for such bank or trust company as shall be

1.07 through the Exchange Agent, certificates evidencing the Guarantor Common
Shares issuable pursuant to Section 1.06(a), the cash to be paid in lieu of
fractional shares in exchange for outstanding Shares pursuant to Section
1.06(f) and the cash or other property in respect of any dividends or other
distributions payable pursuant to Section 1.07(c).  Each certificate
representing shares of Company Preferred Stock after the Effective Time shall
represent an equal number of Surviving Company Preferred Stock without any
additional action by the holder thereof.



                                      -9-



          (b)  Exchange Procedures.  As soon as reasonably practicable after
the Effective Time, Parent will cause the Exchange Agent to mail to each
holder of record of Certificates (i) a letter of transmittal (which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon proper delivery of the Certificates to the
Exchange Agent and shall be in such form and have such other provisions as
Parent may reasonably specify), and (ii) instructions to effect the surrender
of the Certificates in exchange for the certificates evidencing Guarantor
Common Shares and cash in lieu of fractional shares.  Upon surrender of a
Certificate for cancellation to the Exchange Agent together with such letter
of transmittal, duly executed, and such other customary documents as may be
required pursuant to such instructions, the holder of such Certificate shall
be entitled to receive in exchange therefor solely (A) certificates
evidencing that number of whole Guarantor Common Shares which such holder has
the right to receive in accordance with Section 1.06(a) in respect of the
Shares formerly evidenced by such Certificate and (B) cash in respect of
fractional shares as provided in Section 1.06(f) (the Guarantor Common Shares
and cash in respect of fractional shares being referred to, collectively, as
the "Merger Consideration"), except that Shares held at the Effective Time in
book-entry form shall be exchanged for Merger Consideration in accordance
with the customary procedures of the Depository Trust Company.

          The holder of such Certificate, upon its exchange for Guarantor
Common Shares, shall also receive any dividends or other distributions to
which such holder is entitled pursuant to Section 1.07(c).  Certificates
surrendered shall forthwith be canceled following the Effective Time.  In the
event of a transfer of ownership of Shares which is not registered in the
transfer records of the Company as of the Effective Time, the Merger
Consideration, dividends and distributions may be issued and paid in
accordance with this Article I to a transferee if the Certificate evidencing
such Shares is presented to the Exchange Agent, accompanied by all documents
required to evidence and effect such transfer pursuant to this Section
1.07(b) and by evidence that any applicable stock transfer taxes have been
paid.  Until so surrendered, each outstanding Certificate that, prior to the
Effective Time, represented Shares will be deemed from and after the
Effective Time, for all corporate purposes, other than the payment of
dividends or other distributions, to evidence the ownership of the number of
full Guarantor Common Shares, and cash in respect of fractional shares, into
which such Shares shall have been so converted.

          (c)  Distributions with Respect to Unexchanged Shares.  No
dividends or other distributions declared or made after the Effective Time
with respect to Guarantor Common Shares with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate
with respect to the Guarantor Common Shares such holder is entitled to
receive until the holder of such Certificate shall surrender such Certificate

                                     -10-



in accordance with the provisions of Section 1.07(b).  Subject to applicable
law, following surrender of any such Certificate, there shall be paid to the
record holder of the certificates representing whole Guarantor Common Shares
issued in exchange therefor, without interest, at the time of such surrender,
the amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such whole Guarantor Common
Shares.

          (d)  Transfers of Ownership.  If any certificate for Guarantor
Common Shares is to be issued in a name other than that in which the
Certificate surrendered in exchange therefor is registered, it will be a
condition of the issuance thereof that the Certificate so surrendered shall
be properly endorsed and otherwise in proper form for transfer and that the
person requesting such exchange shall have paid to Parent or any agent
designated by it any transfer or other taxes required by reason of the
issuance of a certificate for Guarantor Common Shares in any name other than
that of the registered holder of the Certificate surrendered, or establish to
the satisfaction of Parent or any agent designated by it that such tax has
been paid or is not payable.

          (e)  Escheat.  Neither Parent, Merger Sub nor the Company nor any
of their respective affiliates shall be liable to any holder of Company
Common Stock for any Merger Consideration delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

          (f)  Withholding Rights.  The Exchange Agent shall be entitled to
deduct and withhold from the Merger Consideration otherwise payable pursuant
to this Agreement to any holder of Company Common Stock, and from any cash
dividends or other distributions that the holder is entitled to receive under
Section 1.07(c), such amounts as the Exchange Agent is required to deduct and
withhold with respect to the making of such payment under the Code, or any
provision of state, local or non-United States tax law.  To the extent that
amounts are so withheld by the Exchange Agent, such portion of the Merger
Consideration and other such amounts payable under Section 1.07(c) that are
withheld shall be treated for all purposes of this Agreement as having been
received by the holder of the Shares in respect of which such deduction and
withholding was made by the Exchange Agent.

          (g)  Undistributed Certificates.  Any portion of the certificates
evidencing the Guarantor Common Shares, the cash to be paid in lieu of
fractional shares and the cash or other property in respect of dividends or
other distributions supplied to the Exchange Agent which remains
undistributed to the holders of the Certificates for one year after the
Effective Time shall be delivered to Parent, upon demand, and any holders of
the Certificates who have not theretofore complied with this Section 1.07
shall thereafter look only to Parent for payment of their claim for Merger


                                     -11-



Consideration and any dividends or distributions with respect to Guarantor
Common Shares.

          Section 1.08  Stock Transfer Books.  At the Effective Time, the
stock transfer books of the Company shall be closed, and there shall be no
further registration of transfers of the Company Common Stock thereafter on
the records of the Company.

          Section 1.09  No Further Ownership Rights in Company Common Stock.
The Merger Consideration delivered upon the surrender for exchange of Shares
in accordance with the terms hereof shall be deemed to have been issued in
full satisfaction of all rights pertaining to such Shares, and there shall be
no further registration of transfers on the records of the Surviving
Corporation of Shares which were outstanding immediately prior to the
Effective Time.  If, after the Effective Time, Certificates are presented to
the Surviving Corporation for any reason, they shall be canceled and
exchanged as provided in this Article I.

          Section 1.10  Lost, Stolen or Destroyed Certificates.  In the event
any Certificates shall have been lost, stolen or destroyed, the Exchange
Agent shall issue in exchange for such lost, stolen or destroyed
Certificates, upon the making of an affidavit of that fact by the holder
thereof, such Merger Consideration and any dividends or other distributions
as may be required pursuant to this Article I; provided, however, that Parent
may, in its discretion and as a condition precedent to the issuance thereof,
require the owner of such lost, stolen or destroyed Certificates to deliver a
bond in such sum as it may reasonably direct as indemnity against any claim
that may be made against Guarantor, Parent or the Exchange Agent with respect
to the Certificates alleged to have been lost, stolen or destroyed.

          Section 1.11  Tax Consequences.  It is intended by the parties
hereto that the Merger shall constitute a reorganization within the meaning
of Section 368(a) of the Code.  The parties hereto hereby adopt this
Agreement as a "plan of reorganization" within the meaning of Sections 1.368-
2(g) and 1.368-3(a) of the United States Treasury Regulations.

          Section 1.12  Taking of Necessary Action; Further Action.  Each of
Parent, Merger Sub and the Company will take, and cause their affiliates to
take, all such reasonable and lawful actions as may be necessary or
appropriate in order to effectuate the Merger and the other transactions
contemplated by this Agreement in accordance with this Agreement as promptly
as possible.  If, at any time after the Effective Time, any such further
action is necessary or desirable to carry out the purposes of this Agreement
and to vest the Surviving Corporation with full right, title and possession
to all assets, property, rights, privileges, powers and franchises of the
Company and Merger Sub, the officers and directors of the Company and Merger
Sub immediately prior to the Effective Time are fully authorized in the name

                                     -12-



of their respective corporations or otherwise to take, and will take, all
such lawful and necessary action.

                                  ARTICLE II
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          The Company hereby represents and warrants to Parent and Merger Sub
as follows:

          Section 2.01  Organization and Qualification; Subsidiaries; Material
Adverse Effect.

          (a)  Each of the Company and its subsidiaries is an entity duly
organized, validly existing and (to the extent the concept of good standing
exists in the applicable jurisdiction) in good standing under the laws of the
jurisdiction of its organization and has the requisite corporate or other
power and authority necessary to own, lease and operate the properties it
purports to own, operate or lease and to carry on its business as it is now
being conducted, except where the failure to be so organized, existing and in
good standing or to have such power or authority would not reasonably be
expected to have a Material Adverse Effect.  Each of the Company and its
subsidiaries is duly qualified or licensed as a foreign corporation to do
business, and is in good standing, in each jurisdiction where the character
of its properties owned, leased or operated by it or the nature of its
activities makes such qualification or licensing necessary, except for such
failures to be so duly qualified or licensed and in good standing that would
not reasonably be expected to have a Material Adverse Effect.  A true and
complete list of all of the Company's subsidiaries is included as an exhibit
to the Company's 1999 Annual Report on Form 10-K.  A list of all subsidiaries
of the Company together with the jurisdiction of organization of each such
subsidiary and the percentage of each such subsidiary's outstanding capital
stock owned by the Company or another subsidiary of the Company (in the case
of any non-U.S. subsidiaries, without giving effect to any qualifying share
ownerships of less than 1%) is contained in Section 2.01 of the written
disclosure schedule previously delivered by the Company to the Parent (the
"Company Disclosure Schedule").  Except as set forth in Section 2.01 of the
Company Disclosure Schedule or the Company SEC Documents, neither the Company
nor any of its subsidiaries directly or indirectly owns any equity or similar
interest in, or any interest convertible into or exchangeable or exercisable
for, any equity or similar interest in, any corporation, partnership, joint
venture or other business association or entity (other than its wholly-owned
subsidiaries), with respect to which interest the Company or a subsidiary has
invested (and currently owns) or is required to invest $5 million or more,
excluding securities in any publicly-traded company held for investment by
the Company and comprising less than five-percent of the outstanding stock of
such company.


                                     -13-



          (b)  When used in connection with the Company or any of its
subsidiaries or Guarantor or any of its subsidiaries, as the case may be, the
term "Material Adverse Effect" means any change, effect or circumstance that
is or is reasonably likely to be materially adverse to the business, assets
(including intangible assets), financial condition or results of operations
of the Company and its subsidiaries or Guarantor and its subsidiaries, as the
case may be, in each case taken as a whole; provided, however, that the
following shall be excluded from the definition of Material Adverse Effect
and from any determination as to whether a Material Adverse Effect has
occurred or may occur:  changes, effects or circumstances, that are
applicable to (A) the healthcare, pharmaceutical or medical device industries
generally, (B) the United States securities markets generally, (C) personnel
and other changes customarily attendant to transactions of the type
contemplated by this Agreement and (D) changes in economic, regulatory or
political conditions generally.

          (c)  The failure of a representation or warranty to be true and
correct, either individually or together with the failure of other
representations or warranties to be true and correct, or the failure to
perform an obligation, agreement or covenant shall be deemed to have a
Material Adverse Effect if (x) the business, assets (including intangible
assets), financial condition, or results of operations of the Company and its
subsidiaries, or of Guarantor and its subsidiaries, as the case may be, in
each case taken as a whole, are or are reasonably likely to be materially
worse than if such representation or warranty had been true and correct or
such obligation, agreement or covenant had been performed, excluding,
however, the effects of the changes specified in the proviso set forth in
Section 2.01(b), (y) in the case of the Company, such representation or
warranty materially misstates the capitalization of the Company and/or its
subsidiaries or (z) the failure of such representation or warranty to be true
and correct or the failure to perform such obligation, agreement or covenant
materially and adversely affects the ability of the Company or Parent, Merger
Sub and Guarantor as the case may be, timely to consummate the transactions
contemplated by this Agreement and, in the case of Guarantor, the Guarantee.

          Section 2.02  Certificate of Incorporation and By-laws.  The Company
has heretofore made available to Parent a complete and correct copy of its
Restated Certificate of Incorporation and By-laws as amended to date (the
"Company Charter Documents"), and will make available to Parent, as promptly
as practicable, the Certificate of Incorporation and By-laws (or equivalent
organizational documents) of each of its subsidiaries reasonably requested by
Parent (the "Subsidiary Documents").  All such Company Charter Documents and
Subsidiary Documents are in full force and effect.  Neither the Company nor
any of its subsidiaries is in violation of any of the provisions of its
Certificate of Incorporation or By-laws or equivalent organizational
documents, except for violations of the documents which do not and are not
reasonably likely to materially interfere with the operations of such entity.

                                     -14-



          Section 2.03  Capitalization.  The authorized capital stock of the
Company consists of 300,000,000 shares of the Company Common Stock and

violation of preemptive or similar rights, (ii) no shares of the Company
Common Stock were held by subsidiaries of the Company, (iii) 8,028,813 shares

and available for future issuance pursuant to the Company ESPP.  There are
98,330 shares of the Company Preferred Stock issued and outstanding, all of
which are validly issued, fully paid and nonassessable and there are no
outstanding shares of Series Preferred Stock.  Except as set forth in Section
2.03 of the Company Disclosure Schedule, no change in such capitalization has
occurred since June 26, 2000, except for changes resulting from the exercise
or termination of Company Stock Options or transactions pursuant to the
Company ESPP.  Except as set forth in Section 2.01, this Section 2.03 or
Section 2.11 or in Section 2.03 or Section 2.11 of the Company Disclosure
Schedule or the Company SEC Documents, there are no options, warrants or
other rights, agreements, arrangements or commitments of any character
binding on the Company or any of its subsidiaries relating to the issued or
unissued capital stock of the Company or any of its subsidiaries or
obligating the Company or any of its subsidiaries to issue or sell any shares
of capital stock of, or other equity interests in, the Company or any of its
subsidiaries.  All shares of the Company Common Stock subject to issuance as
aforesaid, upon issuance on the terms and conditions specified in the
instruments pursuant to which they are issuable, shall be duly authorized,
validly issued, fully-paid and nonassessable.

          Except as disclosed in Section 2.03 of the Company Disclosure
Schedule or the reports, schedules, forms, statements and other documents
(the "Company SEC Documents") filed by the Company with the Securities and
Exchange Commission ("SEC") since June 30, 1997 and prior to the date of this
Agreement, there are no obligations, contingent or otherwise, of the Company
or any of its subsidiaries to repurchase, redeem or otherwise acquire any
shares of the Company Common Stock or the capital stock of any subsidiary.
Except as disclosed in Section 2.03 of the Company Disclosure Schedule or the
Company SEC  Documents, there are no obligations, contingent or otherwise, of
the Company or any of its subsidiaries to provide funds to or make any
investment (in the form of a loan, capital contribution or otherwise) in any
such subsidiary or any other entity other than guarantees of bank obligations
of subsidiaries entered into in the ordinary course of business.  Except as

                                     -15-



set forth in Section 2.01 or 2.03 of the Company Disclosure Schedule, all of
the outstanding shares of capital stock (other than directors' qualifying
shares) of each of the Company's subsidiaries are duly authorized, validly
issued, fully-paid and nonassessable, and all such shares (other than
directors' qualifying shares and a de minimis number of shares owned by
employees of such subsidiaries) are owned by the Company or another
subsidiary free and clear of all security interests, liens, claims, pledges,
agreements, limitations in the Company's voting rights, charges or other
encumbrances of any nature whatsoever.

          Section 2.04  Authority Relative to This Agreement.

          (a)  The Company has all necessary corporate power and authority to

Company Charter Documents and the filings and recording of appropriate merger
documents as required by the NYBCL).

          (b)  Assuming the accuracy of the representations and warranties in
Section 3.14, the provisions of Section 912 of the NYBCL and Article 11,

apply to the Merger.

          (c)  As of the date hereof, the Board of Directors of the Company

executed and delivered by the Company and, assuming the due authorization,
execution and delivery by Guarantor, Parent and Merger Sub of this Agreement
and/or the Guarantee hereof, as applicable, constitutes a legal, valid and

(iii) all agreements which are required to be filed as "material contracts"
with the SEC pursuant to the requirements of the Securities Exchange Act of
1934, as amended, and the SEC's rules and regulations thereunder (the

indenture, credit facility, contract, agreement, lease, license, permit,
franchise or other instrument or obligation to which the Company or any of
its subsidiaries is a party or by which the Company or any of its
subsidiaries or its or any of their respective properties is bound or
affected, except, in the case of clause (ii) or (iii), for any such
conflicts, violations, breaches, defaults or other occurrences that would not


                                     -17-



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

          (c)  The execution and delivery of this Agreement by the Company
does not, and the performance of this Agreement by the Company will not,
require any consent, approval, authorization or permit of, or filing with or
notification to, any governmental, administrative or regulatory authority,
domestic or foreign (each, a "Governmental Authority"), except (i) for
applicable requirements, if any, of the Securities Act of 1933, as amended,

effect of monopolization or restraint of trade ("Non-U.S. Monopoly Laws");
filings and consents as may be required under any environmental, health or
safety law or regulation pertaining to any notification, disclosure or
required approval triggered by the Merger or the transactions contemplated by
this Agreement ("Environmental, Health and Safety Laws"); and the filing and
recordation of appropriate merger or other documents as required by the
NYBCL, (ii) where the failure to obtain such consents, approvals,
authorizations or permits, or to make such filings or notifications, would
not prevent or materially delay consummation of the Merger, or otherwise
prevent or materially delay the Company from performing its material
obligations under this Agreement, or would not otherwise reasonably be
expected, individually or in the aggregate, to have a Material Adverse
Effect, or (iii) as to which any necessary consents, approvals,
authorizations, permits, filings or notifications have heretofore been
obtained or filed, as the case may be, by the Company.

          Section 2.06  Compliance; Permits.  (a)  Except as disclosed in
Section 2.06(a) of the Company Disclosure Schedule or the Company SEC

                                     -18-

Disclosure Schedule or the Company SEC Documents, the Company and its
subsidiaries hold all permits, licenses, easements, variances, exemptions,
consents, certificates, orders and approvals from governmental authorities
which are material to the operation of the business of the Company and its
subsidiaries, taken as a whole, as it is now being conducted (collectively,
the "Company Permits"), except where the failure to hold such the Company
Permits would not reasonably be expected, individually or in the aggregate,
to have a Material Adverse Effect.  The Company and its subsidiaries are in
compliance with the terms of the Company Permits, except as described in the
Company SEC Documents or where the failure to so comply would not reasonably
be expected, individually or in the aggregate, to have a Material Adverse
Effect.

          Section 2.07  SEC Filings; Financial Statements.  (a)  The Company
has filed all reports, schedules, forms, statements and other documents
(including all exhibits to the Company SEC Documents) required to be filed
with the SEC since June 30, 1997.  Except as disclosed in Section 2.07 of the
Company Disclosure Schedule or the Company SEC Documents, such reports,
schedules, forms, statements and other documents (i) were prepared in all
material respects in accordance with the applicable requirements of the
Securities Act or the Exchange Act, as the case may be, and (ii) did not at
the time they were filed (or if amended or superseded by a filing prior to
the date of this Agreement, then on the date of such filing) contain any
untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not misleading.
Except as set forth in Section 2.07 of the Company Disclosure Schedule, none
of the Company's subsidiaries is required to file any forms, reports or other
documents with the SEC.

          (b)  Each of the consolidated financial statements (including, in
each case, any related notes thereto) contained in the Company SEC Documents
was prepared in accordance with United States generally accepted accounting
principles ("GAAP") applied on a consistent basis throughout the periods
involved (except as may be indicated in the notes thereto or in the Company
SEC Documents), and each fairly presents in all material respects, the
consolidated financial position of the Company and its subsidiaries as at the
respective dates thereof and the consolidated results of its operations and
cash flows for the periods indicated, except that the unaudited interim
financial statements were or are subject to normal and recurring year-end
adjustments which were not or are not expected to be material in amount.

          Section 2.08  Absence of Certain Changes or Events.  Except as set
forth in Section 2.08 of the Company Disclosure Schedule or the Company SEC
Documents, since June 30, 1999, the Company has conducted its business in the
ordinary course and there has not occurred: (i) any changes, effects or

circumstances constituting, individually or in the aggregate, a Material
Adverse Effect; (ii) any amendments or changes in the Company Charter
Documents; (iii) any material changes to any Company Employee Plans or other
employee benefit arrangements or agreements, including the establishment of
any new such plans, arrangements or agreements or the extension of coverage
under any such plans, arrangements or agreements to new groups of employees
or other individuals; (iv) any damage to, destruction or loss of any asset of
the Company (whether or not covered by insurance) that would reasonably be
expected, individually or in the aggregate, to have a Material Adverse

principles or practices (other than as required by GAAP subsequent to the
date of this Agreement); or (vi) other than in the ordinary course of
business, any sale of a material amount of assets of the Company.

          Section 2.09  No Undisclosed Liabilities.  Except as set forth in
Section 2.09 of the Company Disclosure Schedule or the Company SEC Documents,
neither the Company nor any of its subsidiaries has any liabilities
(absolute, accrued, contingent or otherwise), except liabilities (a) in the
aggregate adequately provided for in the Company's unaudited balance sheet
(including any related notes thereto) as of March 31, 2000, included in the
Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2000
(the "2000 Balance Sheet"), (b) incurred in the ordinary course of business
and not required under GAAP to be reflected on the 2000 Balance Sheet, (c)
incurred since March 31, 2000 in the ordinary course of business, (d)

Effect.

          Section 2.10  Absence of Litigation.  Except as set forth in
Section 2.10 and Section 2.19(c) of the Company Disclosure Schedule or the
Company SEC Documents or arising out of the transactions contemplated by this
Agreement, there are no claims, actions, suits, proceedings or investigations
pending or, to the knowledge of the Company, threatened against the Company
or any of its subsidiaries, or any properties or rights of the Company or any
of its subsidiaries, before any court, arbitrator or Governmental Authority,
that would reasonably be expected, individually or in the aggregate, to have
a Material Adverse Effect.

          Section 2.11  Employee Benefit Plans; Employment Agreements.  (a)
"Company Employee Plans" shall mean all "employee pension benefit plans" (as
defined in Section 3(2) of the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), all "employee welfare benefit plans" (as defined
in Section 3(1) of ERISA), all non-U.S. non-statutory plans and all other
U.S. and non-U.S. non-statutory bonus, stock option, stock purchase,
incentive, deferred compensation, supplemental retirement, severance and
other similar fringe or employee benefit plans, programs or arrangements

                                     -20-



(including those which contain change of control provisions or pending change
of control provisions), and any employment, executive compensation or
severance agreements (including those which contain change of control
provisions or pending change of control provisions), written or otherwise, as
amended, modified or supplemented, for the benefit of, or relating to, any
former or current employee, officer, director or consultant (or any of their
beneficiaries) of the Company or a subsidiary of the Company. The term
"Affiliate Plan" shall mean any other such plan, program or arrangement with
respect to which the Company or any subsidiary of the Company has or could
reasonably be expected to have any liability, either as a member of a
controlled group of corporations or trades or businesses as defined under
section 414 of the Code and comparable provisions of ERISA, or by contractual
arrangement.  Section 2.11(a) of the Company Disclosure Schedule lists each
Company Employee Plan and each Affiliate Plan. With respect to each plan
included on the Company Disclosure Schedule or the Employee Benefits
Supplemental Disclosure Schedule the Company shall indicate (i) whether such
plan includes a change in control provision, (ii) with respect to employee
benefit welfare plans, whether such plan is fully insured or has a stop-loss
insurance contract and (iii) with respect to the employees set forth on
Exhibit 2.11-A, whether any such employees have entered into an agreement or
a provision of an agreement prohibiting or restricting such employee from
accepting employment or otherwise engaging in activity that is in competition
with the business of the Company or its subsidiaries (other than with respect
to the use of confidential information or trade secrets) after the
termination of such individual's employment with the Company.
Notwithstanding the foregoing, the Company may omit from the Disclosure
Schedule and instead include in Section 2.11 of an employee benefits
supplement to the Company Disclosure Schedule (the "Employee Benefits
Supplemental Disclosure Schedule") the following information, that, because
of time constraints, the Company, in good faith, is not able to list in
Section 2.11(a) of the Company Disclosure Schedule by the date of this
Agreement: any non-material employee benefit welfare plan, any non-U.S. plan
and any agreements relating to leased employees or independent contractors,
as well as the information specified in (ii) above.  The Employee Benefits
Supplemental Disclosure Schedule shall be delivered to Parent within 30 days
after the date hereof.  With respect to each Company Employee Plan listed in
Section 2.11(a) of the Company Disclosure Schedule the Company has provided
or made available to Parent (or will provide or make available to Parent as
promptly as practicable, but in no event later than 30 days after the date
hereof) and with respect to each Company Employee Plan to be listed in
Section 2.11(a) of the Employee Benefits Supplemental Disclosure Schedule,
the Company will upon or as soon as practicable following delivery of the
Employee Benefits Supplemental Disclosure Schedule provide or make available
to Parent copies of (i) each such written Company Employee Plan (or a written
description in English of any Company Employee Plan which is not written and
with respect to Company Employee Plans covering 50 or more participants, a
written description in English of any such plan that is written in a language

                                     -21-



other than English) and any related trust agreement, insurance and other
contract (including a policy), the most recently prepared summary plan
description, summary of material modifications the substance of which is not
already incorporated in the corresponding summary plan description, and
communications distributed to plan participants that could reasonably be
expected to materially modify the terms of any Company Employee Plan, whether
through information actually conveyed in the communication or a failure to
convey information, (ii) the three most recent annual reports on Form 5500
series (or equivalent filing with respect to non-U.S. plans), with
accompanying schedules and attachments, filed with respect to each U.S. or
non-U.S. non-statutory Company Employee Plan required to make such a filing,
(iii) the most recent actuarial valuation, if any, for each Company Employee
Plan and Affiliate Plan subject to Title IV of ERISA and all non-U.S. pension
and post-retirement welfare plans, (iv) the latest reports which have been
filed with the Department of Labor ("DOL") to satisfy the alternative method
of compliance for pension plans for certain selected employees pursuant to
DOL regulation Section 2520.104-23 and (v) the most recent favorable
determination letters issued for each Company Employee Plan and related trust
which is intended to be qualified under Section 401(a) of the Code (and, if
an application for such determination is pending, a copy of the application
for such determination).

          (b)  Except as set forth in Section 2.11(b) of the Company
Disclosure Schedule, (i) none of the Company Employee Plans or Affiliate
Plans promises or provides medical or other welfare benefits to any director,
officer, employee or consultant (or any of their beneficiaries) after their
service with the Company or its subsidiary or affiliate terminates, other
than as required by Section 4980B of the Code or Part 6 of Subtitle B of
Title I of ERISA (hereinafter, "COBRA"), or any similar state laws (ii) none
of the Company Employee Plans or Affiliate Plans is a "multiemployer plan" as
such term is defined in Section 3(37) of ERISA and no non-U.S. Company
Employee Plan is a multiemployer plan and no Company Employee Plan or
Affiliate Plan has incurred any withdrawal liability that remains unsatisfied
and the transactions contemplated herein will not result in the assessment of
any withdrawal liability that could reasonably be expected to have a Material
Adverse Effect; (iii) neither the Company nor any of its subsidiaries has
engaged in a transaction with respect to any Company Employee Plan or
Affiliate Plan which could reasonably be expected to subject the Company or
any subsidiary, directly or indirectly, to a tax, penalty or other liability
for prohibited transactions under ERISA or Section 4975 of the Code and to
the knowledge of the Company no other party in interest or disqualified
person (as defined in Section 3(14) of ERISA and Section 4975 of the Code)
has engaged in any such transaction that, in either case, could reasonably be
expected to have a Material Adverse Effect; (iv) neither the Company or any
of its subsidiaries, nor any executive of the Company or one of its
subsidiaries as fiduciary of the Company Employee Plans has breached any of
the responsibilities or obligations imposed upon fiduciaries under Title I of

                                     -22-



ERISA, which breach would reasonably be expected to result in any liability
to the Company or any subsidiary thereof and to the knowledge of the Company
no other fiduciary of any Company Employee Plan has committed such a breach,
in either case that could reasonably be expected to have a Material Adverse
Effect; (v) all Company Employee Plans and, to the knowledge of the Company,
all Affiliate Plans have been established and maintained substantially in
accordance with their terms and have been operated in compliance in all
material respects with the requirements of applicable law (including, but not
limited to, to the extent applicable, the notification and other requirements
of COBRA, the Health Insurance Portability and Accountability Act of 1996,
the Newborns' and Mothers' Health Protection Act of 1996, the Mental Health
Parity Act of 1996, and the Women's Health and Cancer Rights Act of 1998)
except for such failure as could not reasonably be expected to have a
Material Adverse Effect; (vi) each Company Employee Plan which is intended to
be qualified under Section 401(a) of the Code is the subject of a favorable
determination letter from the Internal Revenue Service (the "IRS"), and, to
the Company's knowledge, nothing has occurred which may reasonably be
expected to impair such determination; (vii) all contributions required to be
made with respect to any Company Employee Plan (whether pursuant to the terms
of such plan, Section 412 of the Code, any collective bargaining agreement,
or otherwise) have been made on or before their due dates (including any
extensions thereof) except to the extent any failure to have made such a
contribution on or before its due date could not reasonably be expected to
result in a current or future material liability of the Company; (viii) with
respect to each Company Employee Plan and Affiliate Plan, no "reportable
event" within the meaning of Section 4043 of ERISA (excluding any such event
for which the 30-day notice requirement has been waived under the regulations
to Section 4043 of ERISA) has occurred with respect to which the Company or
one of its subsidiaries has any material outstanding liability and no Company
action has occurred that resulted or will result in any adverse liability for
any non-U.S. Company Employee Plan that reasonably could be expected to have
a Material Adverse Effect; (ix) none among the Company or any subsidiary
thereof has incurred (or could reasonably be expected to incur) any liability
that remains unsatisfied, or reasonably expects to incur any liability, under
Title IV of ERISA with respect to either a Company Employee Plan or an
Affiliate Plan including, without limitation, with respect to an event
described in Section 4062, 4063 or 4041 of ERISA (other than liability for
premium payments to the Pension Benefit Guaranty Corporation (the "PBGC")
arising in the ordinary course) that, in either case, could reasonably be
expected to have a Material Adverse Effect; (x) other than routine claims for
benefits made in the ordinary course of the operation of the Company Employee
Plans, there are no pending, nor to the Company's knowledge, any threatened,
claims, investigations or causes of action with respect to any U.S. or non-
U.S. non-statutory Company Employee Plan or Affiliate Plan, whether made by a
participant or beneficiary of such a plan, a governmental agency or
otherwise, against the Company or any subsidiary of the Company, any Company
director, officer or employee, any Company Employee Plan, or Affiliate Plan

                                     -23-



or any fiduciary of a Company Employee Plan or Affiliate Plan that could
reasonably be expected to have a Material Adverse Effect; and (xi) each
Company Employee Plan that provides for the provision of post-termination or
post-retirement welfare benefits may by its terms be amended or terminated at
any time subject to applicable law.

          (c)  Section 2.11(c) of the Company Disclosure Schedule sets forth
a true and complete list of each current or former employee, consultant,
officer or director of the Company or any of its subsidiaries who holds (i)
any option to purchase the Company Common Stock as of the date hereof,
together with the number of shares of the Company Common Stock subject to
such option, the exercise price of such option (to the extent determined as
of the date hereof), whether such option is intended to qualify as an
incentive stock option within the meaning of Section 422(b) of the Code (an
"ISO"), and the expiration date of such option; (ii) any shares of Company
Common Stock that are restricted or subject to performance-based vesting; and
(iii) any other award or right (including share units), directly or
indirectly, to receive Company Common Stock (or any other unit of Company
equity) or any amount payable by reference to Company Common Stock (or any
other unit of Company equity), together with the number of shares of Company
Common Stock (or any other unit of Company equity) subject to such right.  To
the extent that, because of time constraints, the Company, in good faith, is
unable to make available the detailed information required in this Section
2.11(c) as of the date hereof, it may be included in Section 2.11(c) of the
Employee Benefits Supplemental Disclosure Schedule if the aggregate number of
shares of Company Common Stock that are covered by outstanding options as of
the date of this agreement has been disclosed to Parent.

          (d)  To the extent not already included and so labeled in Section
2.11(a) or such other section of the Company Disclosure Schedule as is
specifically referenced in Section 2.11(d) of the Company Disclosure
Schedule, Section 2.11(d) of the Company Disclosure Schedule sets forth a
true and complete (i) list of all material outstanding agreements with any
consultants who provide services to the Company or any of its subsidiaries;

the Company Employee Plans; (iii) description of any situation in which a
material portion of the workforce of a component of the Company or its
subsidiaries, whether such component is a subsidiary, unit, work location,
line of business or otherwise, is composed of non-traditional employees,
whether consultants, independent contractors or otherwise, which description
shall include, if applicable, representative samples of agreements with such
non-traditional employees and (iv) list of all worker council agreements of
the Company or any of its subsidiaries with or relating to its employees. To
the extent that, because of time constraints, the Company, in good faith, is
unable to make available the information relating to consultants, leased

                                     -24-



employees and independent contractors as of the date hereof, it may be
included in Section 2.11(d) of the Employee Benefits Supplemental Disclosure
Schedule and provided to the Company within 30 days of the date hereof,
provided, however, that any such agreements that include change in control
provisions shall be included in Section 2.11(d) of the Company Disclosure
Schedule and provided as of the date hereof, to the extent not otherwise so
identified in another section of the Disclosure Schedule.  Section 2.11(d) of
the Company Disclosure Schedule shall indicate which, if any, of such
agreements includes a change in control provision.

          (e)  Except as set forth in Section 2.11(e) of the Company
Disclosure Schedule:  (i) the PBGC has not instituted proceedings to
terminate any Company Employee Plan or, to the knowledge of the Company, an
Affiliate Plan, that is subject to Title IV of ERISA (each, a "Defined
Benefit Plan"); (ii) no Defined Benefit Plan has an accumulated or waived
funding deficiency within the meaning of Section 412 of the Code, nor have
any extensions of any amortization period within the meaning of Section 412
of the Code or Section 302 of ERISA been applied for with respect thereto;
(iii) to the knowledge of the Company, since the date of the most recent
actuarial report prepared by each such plan's actuary with respect to that
plan's most recently completed fiscal year, nothing has occurred that would
materially adversely affect the funding status of such plan; (iv) all
applicable premiums required to be paid to the PBGC with respect to the
Defined Benefit Plans have been paid, except for such failures as could not
reasonably be expected to have a Material Adverse Effect; and (v) no facts or
circumstances exist with respect to any Defined Benefit Plan which would give
rise to a material lien on the assets of the Company under Section 4068 of
ERISA or otherwise.

          (f)  Except as set forth in Section 2.11(f) of the Company
Disclosure Schedule, (i) the Company does not have any outstanding incentive
stock options within the meaning of section 422 of the Code, (ii) the Company
has not granted or awarded any shares of Company Common Stock that, as of the

employment, directorship or other relationship with the Company or any of its
subsidiaries, and (iii) since March 31, 2000, neither the Company nor any of
its subsidiaries has announced, proposed or agreed to any increase in
benefits under any Company Employee Plan (or to the creation or
implementation of new benefits or new plans), any change in employee coverage
which would materially increase the expense of maintaining any Company
Employee Plan, or the grant of any Company Stock Options or other equity
based awards or benefits.

          (g)  Except as set forth in Section 2.11(g) of the Company
Disclosure Schedule, the consummation of the transactions contemplated by

                                     -25-



this Agreement, either alone or in combination with another event, will not
(i) result in any payment (including, without limitation, severance,
unemployment compensation, golden parachute or bonus payments or otherwise)
becoming due to any current or former director, officer, employee or
consultant of the Company, (ii) result in any increase in the amount of
compensation or benefits payable in respect of any director, officer,
employee or consultant of the Company, (iii) accelerate the vesting or timing
of payment of any benefits or compensation payable in respect of any
director, officer, employee or consultant of the Company.

          (h)  Each non-U.S. Company Employee Plan has been maintained in
material compliance with its terms and with the requirements prescribed by
any and all applicable laws (including any special provisions relating to
registered or qualified plans where such non-U.S. Company Employee Plan was
intended to so qualify) and has been maintained in good standing with
applicable regulatory authorities except for such a failure as could not
reasonably be expected to have a Material Adverse Effect.  Except as set
forth on Section 2.11(h) of the Company Disclosure Schedule, to the knowledge
of the Company, since the date of the most recent actuarial report prepared
by each such plan's actuary with respect to that plan's most recently
completed fiscal year, nothing has occurred that would materially adversely
affect the funding status of such plan.

          (i)  There are no complaints, charges or claims against the Company
or any of its subsidiaries pending or to the knowledge of the Company
threatened to be brought by or filed with any governmental authority based
on, arising out of, in connection with or otherwise relating to the
classification of any individual by the Company as an independent contractor
or "leased employee" (within the meaning of section 414(n) of the Code)
rather than as an employee, and no conditions exist under which the Company
or any of its subsidiaries could incur any such liability that in each case
could reasonably be expected to have a Material Adverse Effect.

          Section 2.12  Employment and Labor Matters.  Except as set forth in
Section 2.11(b) or Section 2.12 of the Company Disclosure Schedule or the
Company SEC Documents or in each case as would not reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect:

          (a)  The Company is in compliance with all applicable U.S. and non-
U.S. laws, agreements and contracts relating to employment practices, terms
and conditions of employment, and the employment of former, current, and
prospective employees, independent contractors and "leased employees" (within
the meaning of Section 414(n) of the Code) of the Company including all such
U.S. and non-U.S. laws, agreements and contracts relating to wages, hours,

materially impair the ability of Parent and Merger Sub to consummate the
Merger and the other transactions contemplated by this Agreement or the
ability of Guarantor to fulfill its obligations under the Guarantee.

          (b)  The execution, delivery and performance by Parent and Merger
Sub of this Agreement, the execution, delivery and performance by Guarantor
of the Guarantee and the consummation by Guarantor, Parent and Merger Sub of

require any consent or other action by any Person under, constitute a default
under, or cause or permit the termination, cancellation, acceleration or

Material Agreement or instrument binding upon Guarantor or any of its
subsidiaries or any material license, franchise, permit, certificate,
approval or other similar authorization affecting, or relating in any way to,
the assets or business of the Parent and its subsidiaries; provided that, for
purposes of this subsection 3.04(b)(iii), "Material Agreement" shall mean any
agreement identified in Guarantor's 1999 Form 10-K or in any of Guarantor's
quarterly reports on Form 10-Q filed with respect to any quarter of its 2000

                                     -37-



fiscal year or any agreement entered into since the date of Guarantor's

threatened, except as disclosed in the Guarantor SEC Documents.

          Section 3.06  SEC Filings; Financial Statements.  (a)  Guarantor has

each case, any related notes thereto) contained in the Guarantor SEC
Documents were prepared in accordance with GAAP applied on a consistent basis
throughout the periods involved (except as may be indicated in the notes
thereto or in the Guarantor SEC Documents), and each fairly presents in all
material respects, the consolidated financial position of Guarantor and its

                                     -38-



consolidated subsidiaries as at the respective dates thereof and the
consolidated results of operations and cash flows for the periods indicated,

individually or in the aggregate, a Material Adverse Effect; (ii) any
amendments or changes in the Guarantor Charter Documents; (iii) any damage to
destruction or loss of any assets of Guarantor (whether or not covered by
insurance) that would reasonably be expected, individually or in the
aggregate, to have a Material Adverse Effect; (iv) any material change by
Guarantor in its accounting methods, principles or practices (other than as

31, 2000 (the "2000 Guarantor Balance Sheet"), (b) incurred in the ordinary
course of business and not required under GAAP to be reflected on the 2000
Guarantor Balance Sheet, (c) incurred since March 31, 2000 in the ordinary
course of business, (d) incurred in connection with this Agreement, or the
Merger or the other transactions contemplated hereby, or (e) which would not

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

in light of the circumstances under which it shall be made, is false or
misleading with respect to any material fact, or omit to state any material
fact required to be stated therein or necessary in order to make the
statements made therein not false or misleading, or necessary to correct any
statement in any earlier communication with respect to the solicitation of
proxies for the Company Shareholders Meeting which has become false or
misleading.

          (b)  If at any time prior to the Effective Time any event relating
to Parent, Merger Sub or any of their respective affiliates, officers or
directors should be discovered by Parent or Merger Sub which should be set
forth in an amendment to the Registration Statement or a supplement to the
Proxy Statement/Prospectus, Parent or Merger Sub will promptly inform the
Company.

          (c)  The Registration Statement and the Proxy Statement/Prospectus
shall comply in all material respects with the requirements of all applicable

obligations or liabilities or engaged in any business activities of any type
or kind whatsoever or entered into any agreements or arrangements with any

                                     -44-



          Section 4.02  No Solicitation.

          (a)  The Company shall not, directly or indirectly, through any
officer, director, employee, representative or agent of the Company or any of
its subsidiaries, solicit or encourage the initiation of (including by way of
furnishing information) any inquiries or proposals regarding any merger, sale
of assets, sale of shares of capital stock (including, without limitation, by
way of a tender offer) or similar transactions involving the Company or any
subsidiaries of the Company that if consummated would constitute an
Alternative Transaction (as defined below) (any of the foregoing inquiries or
proposals being referred to herein as an "Acquisition Proposal").  Nothing
contained in this Agreement shall prevent the Board of Directors of the
Company from (i) furnishing information to a third party which has made a
bona fide Acquisition Proposal that the Board of Directors of the Company
concludes in good faith after consulting with a nationally recognized
investment banking firm would, if consummated, constitute a Superior Proposal
(as defined below) not solicited in violation of this Agreement, provided
that such third party has executed an agreement with confidentiality
provisions substantially similar to those then in effect between the Company
and a subsidiary of Guarantor or (ii) subject to compliance with the other
terms of this Section 4.02, including Sections 4.02(c) and (d), considering
and negotiating a bona fide Acquisition Proposal that the Board of Directors
of the Company concludes in good faith after consulting with a nationally
recognized investment banking firm would, if consummated, constitute a
Superior Proposal not solicited in violation of this Agreement; provided,
however, that, as to each of clauses (i) and (ii), the Board of Directors of
the Company reasonably determines in good faith (after due consultation with
independent counsel, which may be Simpson Thacher & Bartlett) that it is or
is reasonably likely to be required to do so in order to discharge properly
its fiduciary duties.

          For purposes of this Agreement, "Alternative Transaction" means any
of (i) a transaction pursuant to which any person (or group of persons) other
than Parent or its affiliates (a "Third Party") acquires or would acquire
more than 25% of the outstanding shares of any class of equity securities of
the Company, whether from the Company or pursuant to a tender offer or
exchange offer or otherwise, (ii) a merger or other business combination
involving the Company pursuant to which any Third Party acquires or would
acquire more than 25% of the outstanding equity securities of the Company or
the entity surviving such merger or business combination, (iii) any
transaction pursuant to which any Third Party acquires or would acquire
control of assets (including for this purpose the outstanding equity
securities of subsidiaries of the Company and securities of the entity
surviving any merger or business combination including any of the Company's
subsidiaries) of the Company, or any of its subsidiaries having a fair market
value (as determined by the Board of Directors of the Company in good faith)
equal to more than 25% of the fair market value of all the assets of the

                                     -45-



Company and its subsidiaries, taken as a whole, immediately prior to such
transaction, or (iv) any other consolidation, business combination,
recapitalization or similar transaction involving the Company or any
"significant subsidiary" (as defined in Rule 1-02 under Regulation S-X) of
the Company, other than the transactions contemplated by this Agreement;
provided, however, that the term Alternative Transaction shall not include
any acquisition of securities by a broker dealer in connection with a bona
fide public offering of such securities.

          For purposes of this Agreement, "Superior Proposal" means any
proposal made by a Third Party to acquire, directly or indirectly, for
consideration consisting of cash and/or securities, all of the Company Common
Stock entitled to vote generally in the election of directors or all or
substantially all the assets of the Company, on terms which the Board of
Directors of the Company reasonably believes (after consultation with a
financial advisor of nationally recognized reputation) to be more favorable
from a financial point of view to its shareholders than the Merger and the
transactions contemplated by this Agreement taking into account at the time
of determination any changes to the financial terms of this Agreement
proposed by Parent; provided, however, that a Superior Proposal may be
subject to a due diligence review of confidential information and to other
customary conditions.

          (b)  The Company shall notify Parent promptly (but in no event
later than 24 hours) after receipt of any Acquisition Proposal, or any
modification of or amendment to any Acquisition Proposal, or any request for
nonpublic information relating to the Company or any of its subsidiaries in
connection with an Acquisition Proposal or for access to the properties,
books or records of the Company or any subsidiary by any person or entity
that informs the Board of Directors of the Company or such subsidiary that it
is considering making, or has made, an Acquisition Proposal.  Such notice to
Parent shall be made orally and in writing, and shall indicate the identity
of the person making the Acquisition Proposal or intending to make an
Acquisition Proposal or requesting non-public information or access to the
books and records of the Company, the terms of any such Acquisition Proposal
or modification or amendment to an Acquisition Proposal, and whether the
Company is providing or intends to provide the person making the Acquisition
Proposal with access to information concerning the Company as provided in
Section 4.02(a).  The Company shall keep Parent fully informed, on a current
basis, of any material changes in the status and any material changes or
modifications in the material terms of any such Acquisition Proposal,
indication or request.  The Company shall also immediately notify Parent,
orally and in writing, if it enters into negotiations concerning any
Acquisition Proposal.

          (c)  Except to the extent the Board of Directors of the Company
reasonably determines in good faith (after due consultation with independent

                                     -46-



counsel, which may be Simpson Thacher & Bartlett) that it is or is reasonably
likely to be required to act to the contrary in order to discharge properly
its fiduciary duties (and, with respect to the approval, recommendation or
entering into any Acquisition Proposal, it may take such contrary action only
after the second business day following Parent's and Merger Sub's receipt of
written notice of the Board of Directors' intention to do so), neither the
Company nor the Board of Directors of the Company shall withdraw or modify,
or propose to withdraw or modify, in a manner adverse to Parent or Merger
Sub, the adoption by such Board of Directors of this Agreement or its
approval of the Merger.

          (d)  The Company and the Board of Directors of the Company shall
not enter into any agreement (other than a confidentiality agreement entered
into not in violation of Section 4.02(a)) with respect to, or otherwise
approve or recommend, or propose to approve or recommend, any Acquisition
Proposal or Alternative Transaction, unless this Agreement has been
terminated in accordance with its terms.

          (e)  Nothing contained in this Section 4.02 shall prohibit the
Company from taking and disclosing to its shareholders a position required by
Rule 14e-2(a) promulgated under the Exchange Act or from making any
disclosure to its shareholders required by applicable law, rule or regulation
or by the NYSE.

          (f)  The Company shall immediately cease and cause to be terminated
any existing discussions or negotiations with any persons (other than Parent
and Merger Sub) conducted heretofore with respect to any of the foregoing.
The Company agrees not to release any third party from the confidentiality
and standstill provisions of any agreement to which the Company is a party.

          (g)  The Company shall ensure that the officers and directors of
the Company and the Company subsidiaries and any investment banker or other
advisor or representative retained by the Company are aware of the
restrictions described in this Section 4.02.  It is understood that any
violation of the restrictions set forth in this Section 4.02 by any officer
or director of the Company or the Company subsidiaries and any investment
banker, attorney or other advisor or representative of the Company shall be
deemed to be a breach of this Section 4.02 by the Company.

          Section 4.03  Conduct of Business by Guarantor.  During the period
from the date of this Agreement and continuing until the earlier of the
termination of this Agreement or the Effective Time, Parent covenants and
agrees that, except as set forth in Section 4.03 of the Parent Disclosure
Schedule or unless the Company shall otherwise agree in writing, Parent shall
take all action necessary so that (i) Guarantor shall conduct its business,
and cause the businesses of its subsidiaries to be conducted, in the ordinary
course of business and consistent with past practice, including actions taken

                                     -47-



by Guarantor or its subsidiaries in contemplation of the Merger, and (ii)
Guarantor shall not directly or indirectly do, or propose to do, any of the

                             ADDITIONAL AGREEMENTS

          Section 5.01  Proxy Statement/Prospectus; Registration Statement.

          (a)  As promptly as practicable after the execution of this
Agreement, the Company shall, and Parent shall cause Guarantor to, prepare
and file with the SEC, preliminary proxy materials which shall constitute the
Proxy Statement/Prospectus and, if the parties so agree at the time, the
Registration Statement.  As promptly as practicable after comments are
received from the SEC thereon and after the furnishing by the Company and
Guarantor of all information required to be contained therein, the Company
shall, and Parent shall, and shall cause Guarantor to, file with the SEC, the
definitive Proxy Statement/Prospectus and the Registration Statement (or, if
the Registration Statement has been previously filed, an amendment thereto)

                                     -48-



relating to the adoption of this Agreement by the Company's shareholders as
set forth in Section 2.04(c) and the other transactions contemplated hereby,
and to the payment of the Merger Consideration in the form of Guarantor
Common Shares pursuant to this Agreement, and shall use all reasonable
efforts to cause the Registration Statement to become effective, and the
Company shall mail the Proxy Statement/Prospectus to its shareholders as soon
thereafter as practicable. Parent shall also cause Guarantor to take any
action (other than qualifying to do business in any jurisdiction in which it
is not now so qualified or to file a general consent to service of process)
required to be taken under the applicable state securities laws in connection
with the issuance of Guarantor Common Shares in connection with the Merger,
and the Company shall furnish to Guarantor all information concerning the
Company and the holders of capital stock of the Company as may be reasonably
requested in connection with any such action and the preparation, filing and
distribution of the Proxy Statement/Prospectus.  No filing of, or amendment
or supplement to, or correspondence to the SEC or its staff with respect to
the Proxy Statement/Prospectus will be made by the Company or Guarantor,
without providing the other party a reasonable opportunity to review and
comment thereon.  Parent will advise the Company, promptly after Guarantor
receives notice thereof, of the time when the Registration Statement has
become effective or any supplement or amendment has been filed, the issuance
of any stop order, the suspension of the qualification of the Guarantor
Common Shares issuable in connection with the Merger for offering or sale in
any jurisdiction, or any request by the SEC for amendment of the Registration
Statement or comments thereon and responses thereto or requests by the SEC
for additional information.  The Company will advise Parent, promptly after
it receives notice thereof, of any request by the SEC for the amendment of
the Proxy Statement/Prospectus or comments thereon and responses thereto or
requests by the SEC for additional information.  If at any time prior to the
Effective Time any information relating to the Company or Parent, or any of
their respective affiliates, officers or directors, should be discovered by
the Company or Parent which should be set forth in an amendment or supplement
to either of the Registration Statement or the Proxy Statement/Prospectus so
that any of such documents would not include any misstatement of a material
fact or omit to state any material fact necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading, the party which discovers such information shall promptly notify
the other parties hereto and an appropriate amendment or supplement
describing such information shall be promptly filed with the SEC and, to the
extent required by law, disseminated to the shareholders of the Company.

          (b)  Parent shall cause Guarantor to include as an exhibit to the
Registration Statement tax opinions of PricewaterhouseCoopers LLP and Simpson
Thacher & Bartlett, in form and substance reasonably satisfactory to Parent
and to the Company, on the basis of customary facts, representations,
warranties, covenants and assumptions set forth in such opinions, to the
effect that the Merger will be treated for United States federal income tax

                                     -49-



purposes as a reorganization within the meaning of Section 368(a) of the Code
that is not subject to Section 367(a)(1) of the Code pursuant to Treasury
Regulation Section 1.367(a)-(3)(c) (other than with respect to Company
shareholders who are or will be "five-percent transferee shareholders" within
the meaning of Treasury Regulation Section 1.367(a)-3(c)(5)(ii)), and that
each of Guarantor, Parent, Merger Sub and the Company will be a party to the
reorganization within the meaning of Section 368(b) of the Code.

          (c)  The Proxy Statement/Prospectus shall include the
recommendation of the Board of Directors of the Company in favor of adoption
of this Agreement.  Notwithstanding anything to the contrary set forth in
this Section 5.01 or Section 5.02, the Company shall not be obligated to take
the action set forth in the preceding sentence of this Section 5.01(c) or to
take the actions set forth in the second sentence of Section 5.02 to the
extent that the Board of Directors of the Company determines (after due
consultation with independent counsel, which may be Simpson Thacher &
Bartlett) that such action is, or is reasonably likely that such action is,
or is reasonably likely to be, inconsistent with the proper discharge of its
fiduciary duties.

          Section 5.02  Company Shareholders Meeting.  The Company shall
establish a record date for, duly call, give notice of, convene and hold the
Company Shareholders Meeting as promptly as practicable for the purpose of
voting upon the adoption of this Agreement, and the Company shall use all
reasonable efforts to cause the Proxy Statement/Prospectus to be mailed to
the Company's shareholders and to hold the Company Shareholders Meeting as
promptly as practicable after the Registration Statement is declared
effective under the Securities Act. The Company shall solicit from its
shareholders proxies in favor of adoption of this Agreement and shall take
all other reasonable action necessary or advisable to secure the vote or
consent of shareholders in favor of such adoption.

          Section 5.03  Access to Information; Confidentiality. Upon
reasonable notice and subject to restrictions contained in confidentiality
agreements (from which such party shall use reasonable efforts to be
released), the Company shall (and shall cause its subsidiaries to) and Parent
shall take all action necessary such that Guarantor and its subsidiaries
shall (i) afford to the officers, employees, accountants, counsel and other
representatives of the other, reasonable access, during the period after the
execution and delivery of this Agreement and prior to the Effective Time, to
the properties, books, contracts, commitments and records of the Company or
the Guarantor, as applicable, and, (ii) during such period, furnish promptly
to the other all information concerning the business, properties and
personnel of the Company or the Guarantor, as applicable, as such other party
may reasonably request, and each shall make available to the other the
appropriate individuals (including attorneys, accountants and other
professionals) for discussion of the Company's or Guarantor's, as applicable,

                                     -50-



business, properties and personnel as either Parent or the Company may
reasonably request. Such information shall be kept confidential in accordance
with the terms of the confidentiality agreements, dated May 22 and June 14,
2000 (the "Confidentiality Agreements"), between Guarantor and the Company.

          Section 5.04  Consents; Approvals.

          (a)  Subject to Section 5.08, the Company and Parent shall each use
its reasonable best efforts (and Parent shall cause Guarantor to use its
reasonable best efforts) to obtain and to cooperate with each other in order
to obtain all consents, waivers, approvals, authorizations or orders
(including, without limitation, all United States and non-United States
governmental and regulatory rulings and approvals), and the Company and
Parent shall make (and Parent shall cause Guarantor to make) all filings
(including, without limitation, all filings with United States and non-United
States governmental or regulatory agencies) required in connection with the
authorization, execution and delivery of this Agreement by the Company and
Parent and the consummation by them of the transactions contemplated hereby.
The Company and Parent shall furnish (and Parent shall cause Guarantor to
furnish) all information required to be included in the Proxy
Statement/Prospectus and the Registration Statement, or for any application
or other filing to be made pursuant to the rules and regulations of any
United States or non-United States governmental body in connection with the
transactions contemplated by this Agreement.

          (b)  The Company shall, and Parent shall cause Guarantor to, notify
the other promptly upon the receipt of any comments from the SEC or its staff
or any other government officials in connection with any filing made pursuant
hereto and of any request by the SEC or its staff or any other government
officials for amendments or supplements to the Registration Statement, the
Proxy Statement/Prospectus or any other filings or for additional information
and will supply the other with copies of all correspondence between such
party or any of its representatives, on the one hand, and the SEC, or its
staff or any other government officials, on the other hand, with respect to
the Registration Statement, the Proxy Statement/Prospectus, the Merger or any
other filing.  The Company shall, and Parent shall cause Guarantor to, cause
all documents that it is responsible for filing with the SEC or other
regulatory authorities under Section 5.01 and this Section 5.04 to comply in
all material respects with all applicable requirements of law and the rules
and regulations promulgated thereunder.  Whenever any event occurs which is
required to be set forth in an amendment or supplement to the Registration
Statement, the Proxy Statement/Prospectus or any other filing, the Company
will, or Parent will cause Guarantor to, as the case may be, promptly inform
the other of such occurrence and cooperate in filing with the SEC or its
staff or any other government officials and/or mailing to shareholders of
Company, such amendment or supplement.


                                     -51-



          Section 5.05  Agreements with Respect to Affiliates.  The Company
shall deliver to Parent, prior to the date the Registration Statement becomes
effective under the Securities Act, a letter identifying all persons who, at
the Effective Time, are anticipated to be "affiliates" of the Company for
purposes of Rule 145 under the Securities Act.  The Company shall use its
reasonable best efforts to cause each person who is identified as an
"affiliate" in the Affiliate Letter to deliver to Parent prior to the
Effective Time a written agreement in connection with restrictions on
affiliates under Rule 145 under the Securities Act in a form mutually
agreeable to the Company and Parent.

          Section 5.06  Indemnification and Insurance.

          (a)  The Certificate of Incorporation and By-laws of the Surviving
Corporation shall contain the provisions with respect to indemnification set
forth in the Company Charter Documents, which provisions shall not be
amended, modified or otherwise repealed for a period of six years from the
Effective Time in any manner that would adversely affect the rights
thereunder as of the Effective Time of individuals who at the Effective Time
were directors, officers, employees or agents of the Company, unless such
modification is required after the Effective Time by law and then only to the
minimum extent required by such law.

          (b)  The Surviving Corporation shall, to the fullest extent
permitted under applicable law or under the Surviving Corporation's
Certificate of Incorporation or By-laws, indemnify and hold harmless, each
present and former director, officer or employee of the Company or any of its
subsidiaries (collectively, the "Indemnified Parties") against any costs or
expenses (including attorneys' fees), judgments, fines, losses, claims,
damages, liabilities and amounts paid in settlement in connection with any
claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, (x) arising out of or pertaining to the
transactions contemplated by this Agreement or (y) otherwise with respect to
any acts or omissions occurring at or prior to the Effective Time, to the
same extent as provided in the Company Charter Documents or any applicable
contract or agreement as in effect on the date hereof, in each case for a
period of six years after the Effective Time.  In the event of any such
claim, action, suit, proceeding or investigation (whether arising before or
after the Effective Time), (i) any counsel retained by the Indemnified
Parties for any period after the Effective Time shall be reasonably
satisfactory to the Surviving Corporation, (ii) after the Effective Time, the
Surviving Corporation shall pay the reasonable fees and expenses of such
counsel, promptly after statements therefor are received, provided that the
Indemnified Parties shall be required to reimburse the Surviving Corporation
for such payments in the circumstances and to the extent required by the
Company Charter Documents, any applicable contract or agreement or applicable
law, and (iii) the Surviving Corporation will cooperate in the defense of any

                                     -52-



such matter; provided, however, that the Surviving Corporation shall not be
liable for any settlement effected without its written consent (which consent
shall not be unreasonably withheld); and provided, further, that, in the
event that any claim or claims for indemnification are asserted or made
within such six-year period, all rights to indemnification in respect of any
such claim or claims shall continue until the disposition of any and all such
claims.  The Indemnified Parties as a group may retain only one law firm to
represent them in each applicable jurisdiction with respect to any single
action unless there is, under applicable standards of professional conduct, a
conflict on any significant issue between the positions of any two or more
Indemnified Parties, in which case each Indemnified Person with respect to
whom such a conflict exists (or group of such Indemnified Persons who among
them have no such conflict) may retain one separate law firm in each
applicable jurisdiction.

          (c)  The Surviving Corporation shall honor and fulfill in all
respects the obligations of the Company pursuant to indemnification
agreements and employment agreements (the parties under such agreements being
referred to as the "Covered Persons") with the Company's directors and
officers existing at or before the Effective Time, provided such agreements
do not violate Section 4.01(f).

          (d)  In addition, Parent will provide, or cause the Surviving
Corporation to provide, for a period of not less than six years after the
Effective Time, the Company's current directors and officers with an
insurance and indemnification policy that provides coverage for events
occurring at or prior to the Effective Time (the "D&O Insurance") that is no
less favorable than the existing policy or, if substantially equivalent
insurance coverage is unavailable, the best available coverage; provided,
however, that Parent and the Surviving Corporation shall not be required to
pay an annual premium for the D&O Insurance in excess of 200% of the annual
premium currently paid by the Company for such insurance, but in such case
shall purchase as much such coverage as possible for such amount.

          (e)  From and after the Effective Time, Parent shall
unconditionally guarantee the timely payment of all funds owing by, and the
timely performance of all other obligations of, the Surviving Corporation
under this Section 5.06.

          (f)  This Section shall survive the consummation of the Merger at
the Effective Time, is intended to benefit the Company, the Surviving
Corporation, the Indemnified Parties and the Covered Persons, shall be
binding on all successors and assigns of the Surviving Corporation and shall
be enforceable by the Indemnified Parties and the Covered Persons.

          Section 5.07  Notification of Certain Matters.  The Company shall
give prompt notice to Parent, and Parent shall give prompt notice to the

                                     -53-



Company, of (i) the occurrence or nonoccurrence of any event the occurrence
or nonoccurrence of which would reasonably be expected to cause any
representation or warranty contained in this Agreement to be materially
untrue or inaccurate, or (ii) any failure of the Company, Parent or Merger
Sub, as the case may be, materially to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it hereunder;
provided, however, that the delivery of any notice pursuant to this Section
shall not limit or otherwise affect the remedies available hereunder to the
party receiving such notice; and provided further that failure to give such
notice shall not be treated as a breach of covenant for the purposes of
Sections 7.01(h) unless the failure to give such notice results in material
prejudice to the other party.

          Section 5.08  Further Action/Tax Treatment.

          (a)  Upon the terms and subject to the conditions hereof, each of
the parties hereto shall use all reasonable efforts to, and Parent shall
cause Guarantor to use all reasonable efforts to, take, or cause to be taken,
all actions and to do, or cause to be done, all other things necessary,
proper or advisable to consummate and make effective as promptly as
practicable the transactions contemplated by this Agreement, to obtain in a
timely manner all necessary waivers, consents and approvals and to effect all
necessary registrations and filings, and otherwise to satisfy or cause to be
satisfied all conditions precedent to its obligations under this Agreement.
The foregoing covenant shall include the obligation by Guarantor to agree to
divest, abandon, license, hold separate or take similar action with respect
to any assets (tangible or intangible) which are not material to Guarantor or
the Company (but shall not include any obligation by Guarantor to agree to
divest, abandon, license, hold separate or take similar action with respect
to any material assets (tangible or intangible) of Guarantor or the Company).
For this purpose, assets shall be deemed not to be material to the Company,
if they account for no more than 2% of the total revenues of the Company and
its subsidiaries taken as a whole, or to Guarantor, if they account for no
more than 2% of the total revenues of Guarantor's Healthcare Group.

          (b)  Each of Parent, Merger Sub and the Company shall, and Parent
shall cause Guarantor to, use its reasonable best efforts to cause the Merger
to qualify, and will not (both before and after the Effective Time) take any
actions, or fail to take any action, which could reasonably be expected to
prevent the Merger from qualifying as a reorganization under the provisions
of Section 368(a) of the Code that is not subject to Section 367(a)(1) of the
Code pursuant to Treasury Regulation Section 1.367(a)-(3)(c) (other than with
respect to Company shareholders who are or will be "five-percent transferee
shareholders" within the meaning of Treasury Regulation Section
1.367(a)-3(c)(5)(ii)).  Parent shall, and shall cause the Surviving
Corporation and Guarantor to, report, to the extent required by the Code or
the regulations thereunder, the Merger for income tax purposes as a

                                     -54-



reorganization within the meaning of Section 368 of the Code.  Each of Parent
and the Company shall make, and shall cause their affiliates to make, such
representations, warranties and covenants as shall be requested reasonably in
the circumstances by PricewaterhouseCoopers LLP and Simpson Thacher &
Bartlett in order for such firms to render their opinions referred to in
Section 5.01(b).

          Section 5.09  Public Announcements.  Parent and the Company shall
consult with each other before issuing (and in the case of Parent, before
Guarantor issues) any press release or making any written public statement
with respect to the Merger or this Agreement and shall not issue any such
press release or make any such public statement without the prior consent of
the other party, which shall not be unreasonably withheld; provided, however,
that either party may, without the prior consent of the other, issue such
press release or make such public statement as may upon the advice of counsel
be required by law or the rules and regulations of the NYSE if it has used
all reasonable efforts to consult with the other party.

          Section 5.10  Guarantor Common Shares.

          (a)  Parent shall obtain from Guarantor, and shall cause Guarantor
to transfer to Parent, the Guarantor Common Shares to be delivered by Parent
to the holders of Company Common Stock in the Merger.

          (b)  Parent shall cause Guarantor to use its best efforts to cause
the Guarantor Common Shares to be delivered by Parent to the holders of
Company Common Stock in the Merger or to be issued upon exercise of the
Adjusted Options to be listed, upon official notice of issuance, on the NYSE
prior to the Effective Time.

          (c)  Parent shall cause Guarantor on a timely basis to take any
action required to be taken under non-U.S. securities laws in connection with
the issuance of Guarantor Common Shares in the Merger.

          Section 5.11  Stock Options and ESPP.  (a)  At the Effective Time,
Parent shall take all necessary action to provide that each outstanding
Company Stock Option, whether or not then exercisable, will continue to have,
and be subject to, the same terms and conditions set forth in the relevant
Company Stock Option Plan and applicable award agreement immediately prior to
the Effective Time; provided, however, that all Company Stock Options, other
than Company Stock Options granted after the date hereof, shall be 100%
vested and exercisable at the Effective Time, except that, (i) each Company
Stock Option will be exercisable (or will become exercisable in accordance
with its terms) for that number of whole Guarantor Common Shares equal to the
product of the number of shares of Company Common Stock that were issuable
upon exercise of such the Company Stock Option immediately prior to the
Effective Time multiplied by the Exchange Ratio, rounded to the nearest whole

                                     -55-



number of Guarantor Common Shares, (ii) the per share exercise price for the
Guarantor Common Shares issuable upon exercise of such Company Stock Option
will be equal to the quotient determined by dividing the exercise price per
share of the Company Common Stock at which such Company Stock option was
exercisable immediately prior to the Effective Time by the Exchange Ratio,
rounded to the nearest whole cent and (iii) Parent or the Company shall take
all necessary actions to enable the holders of such Company Stock Options to
effect a "brokered cashless exercise" of such options as of the Effective
Time or promptly thereafter (each such Company Stock Option, as modified, an
"Adjusted Option").

          (b)  Parent will cause Guarantor to take all corporate action
necessary to reserve for issuance a sufficient number of Guarantor Common
Shares for delivery upon exercise of the Adjusted Options and to file a
registration statement on Form S-8 for the Guarantor Common Shares issuable
with respect to Adjusted Options as of or as soon as practicable after the
Effective Time and shall maintain the effectiveness of such registration
statement thereafter for so long as any of such options or other rights
remain outstanding.

          (c)  Beginning on the date hereof, the Company shall not establish
any new employee stock purchase plans or extend the availability of the
Company ESPP to any employees not previously included in the Company ESPP,
or, in either case, implement any decisions to do the same, whether or not
such decisions have been communicated to employees.  The Company shall take
such action as is necessary to cause the ending date of the then current
offering period under the Company ESPP to be prior to the Effective Time and
to terminate such plans as of the Effective Time.  All shares of Company
Common Stock under the Company ESPP shall be issued to participants in a
manner such that the shares will be treated as all other shares of Company
Common Stock.  Parent shall, to the extent legally feasible, enable employees
of the Company and its subsidiaries to participate in Guarantor's employee
stock purchase plan, in a manner consistent with the current practice of
Parent's affiliates.

          Section 5.12  Certain Employee Benefits.

          (a)  From the Effective Time through June 30, 2001 (the "Benefits
Continuation Period"), the Surviving Corporation shall provide each person
who, as of the Effective Time, is an employee of the Company or any
subsidiary of the Company (a "Company Employee") with employee benefits that
are comparable in the aggregate to those provided to such Company Employee
immediately prior to the Effective Time, provided, however, subject to
applicable law and contractual restrictions, that the Surviving Corporation
shall have the right to amend any Company Employee Plans, including without
limitation, any retiree welfare benefit plans or pension benefit plans, in
effect as of the Effective Time.  Notwithstanding the foregoing, from the

                                     -56-



Effective Time through the end of the Benefits Continuation Period the
Surviving Corporation shall maintain severance plans, policies and programs
for the benefit of each Company employee that are substantially comparable to
the severance plans, policies and programs of the Company as in effect for
such employee immediately prior to the Effective Time, provided, however,
that, except as required by contractual obligation, no such employee shall be
entitled to a severance benefit in excess of one year's salary and one year's
continuation of health and welfare benefits.

          (b)  After the Benefit Continuation Period the Surviving
Corporation shall provide the Company Employees with employee benefits that
are comparable in the aggregate to those provided to similarly situated
employees of subsidiaries of the Guarantor.  For the avoidance of doubt, it
is understood that the Surviving Corporation shall have no obligation to
provide Company Employees with post-termination welfare or pension benefits,
except to the extent required by applicable law or contractual agreement.

          (c)  With respect to the benefits provided pursuant to this Section
5.12, (i) service accrued by Company Employees during employment with the
Company and its subsidiaries prior to the Effective Time shall be recognized
for eligibility and vesting and, except with respect to defined benefit
plans, benefit accrual, (ii) any and all pre-existing condition limitations
(to the extent such limitations did not apply to a pre-existing condition
under the applicable Company Employee Plan) and eligibility waiting periods
under any group health plan shall be waived with respect to such Company
Employees and their eligible dependents, and (iii) Company Employees shall be
given credit for amounts paid under a Company Employee Plan during the same
period for purposes of applying deductibles, co-payments and out-of-pocket
maximums as though such amounts had been paid in accordance with the terms
and conditions of the employee welfare plans maintained by the Surviving
Corporation or the applicable subsidiary of the Guarantor.

          (d)  It is expressly agreed that (i) the provisions of Section 5.12
are not intended to be for the benefit of or otherwise enforceable by any
third party, including, without limitation, any Company Employees and (ii)
nothing herein shall prevent the Surviving Corporation or any other
subsidiary of Guarantor from amending or modifying any employee benefit plan,
program or arrangement in any respect or terminating or modifying the terms
and conditions of employment or other service of any particular employee or
any other person.

          (e)  Deferred Compensation.  Through the Benefits Continuation
Period, the Surviving Corporation shall continue to maintain the Company's
Income Deferral Plan; provided that prior to the Effective Time such plan
shall be amended to eliminate the Hypothetical Company Stock Fund and all
balances in such Stock Fund shall be transferred to another fund in the Plan.
As of July 1, 2001, eligible active Company Employees shall be given the

                                     -57-



opportunity to participate in and transfer their Income Deferral Plan
balances to the Guarantor Deferred Compensation Plan, the Company's Income
Deferral Plan shall be terminated and any remaining accounts shall be
distributed as provided under the Income Deferral Plan.

          (f)  Common Stock or Stock Units under Incentive Compensation Plans
or Programs.  Awards payable in shares of Company Common Stock under any
Company Incentive Compensation Plan, program or agreement not paid out or
deferred prior to the Effective Time shall be converted to an award payable
in cash only.  Guarantor will be under no obligation to issue any Guarantor
Common Shares pursuant to any Company Incentive Compensation Plan, program or
agreement after the Effective Time.

          Section 5.13  Redemption of the Surviving Preferred Stock.
Promptly following the Effective Time, the Surviving Corporation shall redeem
all of the outstanding shares of the Surviving Preferred Stock in accordance
with the applicable provisions of the Surviving Corporation's Certificate of
Incorporation, with the redemption proceeds payable out of the Company's
assets. In no event shall Parent or any affiliate thereof (other than a
subsidiary of the Company) reimburse the Surviving Corporation for such
redemption payments.

          Section 5.14  Accountants Letters.  Upon reasonable notice from the
other, the Company shall use its best efforts to cause Ernst & Young LLP to
deliver to Parent, and Parent shall use its best efforts to cause
PricewaterhouseCoopers to deliver to the Company, a letter covering such
matters as are reasonably requested by Parent or the Company, as the case may
be, and as are customarily addressed in accountants' "comfort letters."

          Section 5.15  Compliance with State Property Transfer Statutes.
The Company agrees that it shall use its reasonable commercial efforts to
comply promptly with all requirements of applicable state property transfer
laws as may be required by the relevant state agency and shall take all
action necessary to cause the transactions contemplated hereby to be effected
in compliance with applicable state property transfer laws, except where the
failure to so comply will not materially affect the right to use or enjoy any
applicable property after the Effective Time.  The Company, after
consultation with Parent, shall determine which actions must be taken prior
to or after the Effective Time to comply with applicable state property
transfer laws.  The Company agrees to provide Parent with any documents
required to be submitted to the relevant state agency prior to submission,
and the Company shall not take any action to comply with applicable state

not be unreasonably withheld or delayed.  Parent shall provide, and shall
cause Guarantor to provide, to the Company any assistance reasonably
requested by the Company with respect to such compliance.

prior to the Effective Time under any Non-U.S. Monopoly Laws shall have been

expected to have a Material Adverse Effect on the Company, Guarantor or
Guarantor's Healthcare Group;

          (d)  Governmental Actions.  There shall not have been instituted,
pending or threatened any action or proceeding (or any investigation or other
inquiry that is reasonably likely to result in such an action or proceeding)

prevent consummation of the Merger, (ii) prohibiting or seeking to prohibit,

than 2% of the total revenues of Guarantor's Healthcare Group;

          (e)  Illegality.  No statute, rule, regulation or order shall be

opinion of Simpson Thacher & Bartlett, and Parent shall have received a
written opinion of PricewaterhouseCoopers LLP, in form and substance
reasonably satisfactory to each of them, on the basis of customary
representations, warranties, covenants and assumptions set forth in such
opinions, and delivered as of the date of the Effective Time, to the effect
that the Merger will constitute a reorganization within the meaning of
Section 368(a) of the Code that is not subject to Section 367(a)(1) of the
Code pursuant to Treasury Regulation Section 1.367(a)-(3)(c) (other than with
respect to Company shareholders who are or will be "five-percent transferee
shareholders" within the meaning of Treasury Regulation Section

warranties) on and as of the Effective Time, with the same force and effect
as if made on and as of the Effective Time, except for (i) changes
contemplated by this Agreement, (ii) those representations and warranties
which address matters only as of a particular date (which shall have been
true and correct as of such date, subject to clause (iii)), or (iii) where

                                     -60-



the failure to be true and correct would not reasonably be expected,
individually or in the aggregate with all other such failures, to have a
Material Adverse Effect, and Parent and Merger Sub shall have received a
certificate of the Company to such effect signed by the Chief Executive
Officer or Chief Financial Officer of the Company;

          (b)  Agreements and Covenants.  The Company shall have performed or
complied in all material respects with all agreements and covenants required
by this Agreement to be performed or complied with by it on or prior to the
Effective Time, and Parent and Merger Sub shall have received a certificate

Officer of the Company; provided, however, that unless the Company knowingly
breaches Section 4.01(j), the Company shall be deemed to have complied with
Section 4.01(j) unless the failure to comply with such section also results
in the failure of the condition set forth in Section 6.02(a);

          (c)  Consents Obtained.  All material consents, waivers, approvals,
authorizations or orders required to be obtained, and all filings required to
be made, by the Company for the authorization, execution and delivery of this

aggregate with all other such failures, to have a Material Adverse Effect on
the Company, Parent or Guarantor; and

          (d)  Affiliate Agreements.  Parent shall have received from each
person who is identified in the Affiliate Letter as an "affiliate" of the
Company an Affiliate Agreement, and such Affiliate Agreement shall be in full

warranties of Parent and Merger Sub contained in this Agreement shall be true
and correct in all respects (without for this purpose giving effect to
qualifications of materiality contained in such representations and
warranties) on and as of the Effective Time, with the same force and effect
as if made on and as of the Effective Time, except for (i) changes
contemplated by this Agreement, (ii) those representations and warranties
which address matters only as of a particular date (which shall have been
true and correct as of such date, subject to clause (iii)), or (iii) where
the failure to be true and correct could not reasonably be expected,
individually or in the aggregate with all other such failures, to have a


                                     -61-



Material Adverse Effect, and the Company shall have received a certificate to
such effect signed by the President or Chief Financial Officer of Parent;

consummation by them of the transactions contemplated hereby and thereby
shall have been obtained and made by Parent, Merger Sub or Guarantor, except
where the failure to receive such consents, waivers, approvals,
authorizations or orders or to make such filings would not reasonably be

          (d)  Listing.  The Guarantor Common Shares to be delivered by
Parent in connection with the Merger and upon exercise of the Adjusted

                                  ARTICLE VII
                                  TERMINATION

          Section 7.01  Termination.  This Agreement may be terminated at any
time prior to the Effective Time, notwithstanding adoption thereof by the
shareholders of the Company:

          (a)  by mutual written consent duly authorized by the Boards of
Directors of Parent and the Company; or

          (b)  by either Parent or the Company, if the Merger shall not have
been consummated by December 31, 2000 (other than for the reasons set forth
in clause (c) below); provided, however, that the right to terminate this
Agreement under this Section 7.01(b) shall not be available to any party
whose failure to fulfill any obligation under this Agreement has been the
cause of, or resulted in, the failure of the Merger to be consummated on or
prior to such date; or

          (c)  by either Parent or the Company, if the requisite vote of the
shareholders of the Company shall not have been obtained by December 31,
2000, or if the shareholders of the Company shall not have adopted this

                                     -62-



Agreement at the Company Shareholders Meeting; provided, however, that the
Company may not terminate pursuant to this clause if the Company has not
complied with its obligations under Section 5.02; or

          (d)  by either Parent or the Company, if a court of competent
jurisdiction or Governmental Authority shall have issued a nonappealable
final order, decree or ruling or taken any other nonappealable final action
having the effect of permanently restraining, enjoining or otherwise
prohibiting the Merger; or

          (e)  by Parent, if, whether or not permitted to do so by this
Agreement, the Board of Directors of the Company or the Company shall (x) (i)
withdraw, modify or change its approval, adoption or recommendation of this
Agreement or the Merger in a manner adverse to Parent or shall have resolved
to do so; (ii) approve or recommend to the shareholders of the Company an
Acquisition Proposal or Alternative Transaction; (iii) approve or recommend
that the shareholders of the Company tender their shares in any tender or
exchange offer that is an Alternative Transaction; or (iv) fail to include
the recommendation of the Board of Directors of the Company in favor of
approval of this Agreement pursuant to Section 5.01(c) or fail to take the
action required by the second sentence of Section 5.02; or (y) take any
public position or make any disclosures to the Company's shareholders,
whether or not permitted pursuant to Section 4.02, which has the effect of
any of the foregoing (it being understood and agreed that a communication by
the Board of Directors of the Company to the Company's shareholders pursuant
to Rule 14d-9(f)(3) of the Exchange Act, or any similar type of communication
to the Company's shareholders in connection with the making or amendment of a
tender offer or exchange offer, shall not be deemed to constitute a basis for
termination under this Section 7.01(e)); or

          (f)  by Parent or the Company, if any representation or warranty of
the Company or Parent and Merger Sub, respectively, set forth in this
Agreement shall be untrue when made, such that the conditions set forth in
Sections 6.02(a) or 6.03(a), as the case may be, would not be satisfied (a
"Terminating Misrepresentation"); provided that if such Terminating
Misrepresentation is curable prior to December 31, 2000 by the Company or
Parent, as the case may be, through the exercise of its reasonable best
efforts and for so long as the Company or Parent, as the case may be,
continues to exercise such reasonable best efforts, neither Parent nor the
Company, respectively, may terminate this Agreement under this Section
7.01(f); or

          (g)  by Parent, if any representation or warranty of the Company
shall have become untrue such that the condition set forth in Section 6.02(a)
would not be satisfied, or by the Company, if any representation or warranty
of Parent and Merger Sub shall have become untrue such that the condition set
forth in Section 6.03(a) would not be satisfied (in either case, a

                                     -63-



"Terminating Change"), in either case other than by reason of a Terminating
Breach (as hereinafter defined); provided that if any such Terminating Change
is curable prior to December 31, 2000 by the Company or Parent, as the case
may be, through the exercise of its reasonable best efforts, and for so long
as the Company or Parent, as the case may be, continues to exercise such
reasonable best efforts, neither Parent nor the Company, respectively, may
terminate this Agreement under this Section 7.01(g); or

          (h)  by Parent or the Company, upon a breach of any covenant or
agreement on the part of the Company or of Parent or Merger Sub,
respectively, set forth in this Agreement such that the conditions set forth
in Sections 6.02(b) or 6.03(b), as the case may be, would not be satisfied (a
"Terminating Breach"); provided that, except for any breach of the Company's
obligations under Section 4.02, if such Terminating Breach is curable prior
to December 31, 2000 by the Company or Parent, as the case may be, through
the exercise of its reasonable best efforts and for so long as the Company or
Parent, as the case may be, continues to exercise such reasonable best
efforts, neither Parent nor the Company, respectively, may terminate this
Agreement under this Section 7.01(h); or

          (i)  by the Company, if (w) the Board of Directors of the Company
shall have authorized the Company, subject to complying with the terms of
this Agreement, including Section 4.02, to enter into a definitive agreement
with respect to a Superior Proposal and the Company shall have notified
Parent in writing that it intends to enter into such an agreement, attaching
a summary of the material terms thereof, (x) Parent shall not have made,
within two full business days (disregarding any partial business days) of
receipt of the Company's written notification of its intention to enter into
a definitive agreement with respect to a Superior Proposal, an offer that the
Board of Directors of the Company determines, in good faith after
consultation with its financial advisors, is at least as favorable, from a
financial point of view, to the shareholders of the Company as the Superior
Proposal, (y) the Company prior to such termination pursuant to this clause
(i) shall have paid to Parent in immediately available funds the Fee and the
Expenses required to be paid pursuant to Section 7.03(b), and (z) this
Agreement shall not theretofore have been adopted at the Company Shareholders
Meeting; or

          (j)  by Parent, if the Average Share Price is less than the Floor
Price, provided that (i) Parent shall have given the Company notice of its
intention to terminate pursuant to this Section 7.01(j) prior to 5:00 p.m.
New York City time on the business day following the Closing Conditions
Satisfaction Date and (ii) the Company shall not, by 5:00 p.m. New York City
time on the third business day following the Closing Conditions Satisfaction
Date, have delivered a notice to Parent agreeing that the Exchange Ratio
shall equal $47.50 divided by the Floor Price; provided further that if the
Company shall deliver the notice referred to in the preceding clause (ii),

                                     -64-



this Agreement shall not be terminated under this Section 7.01(j) and the
Exchange Ratio for all purposes of this Agreement shall equal $47.50 divided
by the Floor Price or, if the parties shall so agree in their sole and
absolute discretion, a number in excess of $47.50 divided by the Floor Price.

          Section 7.02  Effect of Termination.  In the event of the
termination of this Agreement pursuant to Section 7.01, this Agreement shall
forthwith become void and there shall be no liability on the part of any
party hereto or any of its affiliates, directors, officers or shareholders
except that (i) the Company, Parent or Merger Sub may have liability or
obligations as set forth in Section 7.03 and as set forth in or contemplated
by Section 8.01 hereof.  Notwithstanding the foregoing, nothing herein shall
relieve the Company, Parent or Merger Sub from liability for any willful
breach hereof or willful misrepresentation herein (it being understood that
(x) the provisions of Section 7.03 do not constitute a sole or exclusive
remedy for such willful breach or misrepresentation and (y) the mere
existence of a Material Adverse Effect, by itself, shall not constitute such
a willful breach).

          Section 7.03  Fees and Expenses.  (a)  Except as set forth in this
Section 7.03, all fees and expenses incurred in connection with this
Agreement and the transactions contemplated hereby shall be paid by the party
incurring such expenses, whether or not the Merger is consummated; provided,
however, that Parent and the Company shall share equally (i) all SEC filing
fees and printing expenses incurred in connection with the printing and
filing of the Proxy Statement/Prospectus (including any preliminary materials
related thereto) and the Registration Statement (including financial
statements and exhibits) and any amendments or supplements thereto and (ii)
conveyance and similar taxes required to be paid or which Parent has agreed
should be paid prior to the Effective Time pursuant to Section 5.16.

          (b)  The Company shall pay Guarantor a fee of $110 million (the
"Fee") and shall also pay Parent's and Guarantor's respective actual,
documented and reasonable out-of-pocket expenses relating to the transactions
contemplated by this Agreement (including, but not limited to, fees and
expenses of counsel and accountants and out-of-pocket expenses (but not fees)
of financial advisors) ("Expenses," as applicable to Parent, Guarantor or the
Company) in a combined amount not to exceed $3 million, upon the first to
occur of any of the following events:

          (i)  the termination of this Agreement by Parent or the Company
pursuant to Section 7.01(c) following the Company Shareholders Meeting at
which the shareholders of the Company failed to adopt this Agreement,
provided that (A) the Alternative Transaction Condition is satisfied; and (B)
the Meeting Average Share Price is equal to or greater than the Floor Price;



                                     -65-



          (ii) the termination of this Agreement by Parent pursuant to
Section 7.01(e); or

          (iii) the termination of this Agreement by the Company pursuant
to Section 7.01(i).

          The "Meeting Average Share Price" means the average (rounded to the
nearest 1/10,000) of the Daily Per Share Prices for the five consecutive
trading days ending on the third trading day prior to the Company
Shareholders Meeting.

          The "Floor Price" means (i) $37.00 or (ii) if lower, the Meeting
Average Share Price, but only if Parent in its sole and absolute discretion
irrevocably agrees, by notice to the Company delivered not later than 9:00
a.m. New York City time on the business day prior to the Company Shareholders
Meeting, that the Floor Price shall be the Meeting Average Share Price (in
which case for all purposes of this Agreement, the Floor Price shall equal
the Average Meeting Price); provided that if Parent delivers such a notice,
the Company may postpone the Company Shareholders Meeting for a period of up
to three business days; provided further that the Meeting Average Share Price
shall be computed in such case without regard to such postponement.

          The "Alternative Transaction Condition" shall be satisfied in
respect of a termination of this Agreement if an Alternative Transaction
shall be publicly announced by the Company or any third party within 12
months following the date of termination of this Agreement and such
transaction shall at any time thereafter be consummated on substantially the
terms theretofore announced, and in the case of Section 7.03(b)(i), such
transaction provides for a per Share consideration with a fair market value
greater than $47.50; provided that for purposes of this definition, the
definition of Alternative Transaction set forth in Section 4.02(a) shall be
modified to replace "25%," as it appears in such definition, with "40%."

          (c)  Upon a termination of this Agreement by Parent pursuant to
Section 7.01(h), (i) the Company shall pay to Guarantor and Parent their
respective Expenses relating to the transactions contemplated by this
Agreement in a combined amount not to exceed $3 million, and (ii) the Company
shall pay Guarantor the Fee provided that (I) such Termination Breach is
willful and (II) the Alternative Transaction Condition is satisfied.

          (d)  Upon a termination of this Agreement by Parent pursuant to
Section 7.01(f), the Company shall pay to Guarantor and Parent their
respective Expenses in a combined amount not to exceed $3 million.

          (e)  Upon a termination of this Agreement by the Company pursuant
to Section 7.01(f) or Section 7.01(h), Parent shall pay to the Company its
Expenses in an amount not to exceed $3 million.

                                     -66-



          (f)  The Fee and Expenses payable pursuant to Section 7.03(b) or
Section 7.03(c), or the Expenses payable pursuant to Section 7.03(d) or
Section 7.03(e), shall be paid within one business day after a demand for
payment following the first to occur of any of the events described in the
aforesaid Sections, as applicable; provided that, in no event shall the
Company be required to pay the Fee or any Expenses to Parent, nor shall
Parent be required to pay any Expenses to the Company if, immediately prior
to the termination of this Agreement, the entity otherwise entitled to
receive such fee and/or expenses was in material breach of its obligations
under this Agreement or, in the case of Parent, Merger Sub was in material
breach of its obligations under this Agreement or Guarantor was in material
breach of the Guarantee.

          (g)  Each of the Company, Parent and Merger Sub agrees that the
payments provided for in this Section 7.03 shall be the sole and exclusive
remedy of Parent and Merger Sub upon a termination of this Agreement by
Parent pursuant to Section 7.01(c), (e), (f), (h) or (i), and the payments
provided for in this Section 7.03 shall be the sole and exclusive remedy of
the Company upon a termination of this Agreement by the Company pursuant to
Section 7.01(f) or (h), regardless of the circumstances giving rise to such
termination; provided, however, that the foregoing shall not apply to any
willful breach of this Agreement or any willful misrepresentation hereunder
giving rise to such termination.  Subject to Section 7.03(f), if a party is
entitled to terminate this Agreement pursuant to more than one clause of
Section 7.01, such party shall be entitled to receive the Fees and Expenses
to which it is entitled as a result of any such termination, provided that in
no event shall there be any duplication of payment.

                              GENERAL PROVISIONS

          Section 8.01  Effectiveness of Representations, Warranties and
Agreements.  (a)  Except as otherwise provided in this Section 8.01, the
representations, warranties and agreements of each party hereto shall remain
operative and in full force and effect regardless of any investigation made
by or on behalf of any other party hereto, any person controlling any such
party or any of their officers or directors, whether prior to or after the
execution of this Agreement.  The representations, warranties and agreements
in this Agreement shall terminate at the Effective Time or upon the
termination of this Agreement pursuant to Section 7.01, as the case may be,
except that the agreements set forth in Article I and Sections 5.06 and 5.08
and any other agreement in this Agreement which contemplates performance
after the Effective Time shall survive the Effective Time indefinitely and
those set forth in Sections 7.02 and 7.03 and this Article VIII shall survive
termination indefinitely.  The Confidentiality Agreements shall survive
termination of this Agreement in accordance with their terms.

board of directors or other governing body of such corporation or other legal
entity.

          When reference is made in this Agreement to the Company, Parent or
Guarantor, such reference shall include their respective subsidiaries, as and
to the extent the context so requires, whether or not explicitly stated in
this Agreement.

          Section 8.04  Amendment.  This Agreement may be amended by the
parties hereto by action taken by or on behalf of their respective Boards of
Directors at any time prior to the Effective Time; provided, however, that,
after adoption of this Agreement by the shareholders of the Company, no
amendment may be made which by law requires approval by such shareholders
without such approval.  This Agreement may not be amended except by an
instrument in writing signed by the parties hereto.

          Section 8.05  Waiver.  At any time prior to the Effective Time, any
party hereto may with respect to any other party hereto (a) extend the time
for the performance of any of the obligations or other acts, (b) waive any

of law or public policy, all other conditions and provisions of this
Agreement shall nevertheless remain in full force and effect so long as the

affected in any material manner adverse to any party.  Upon a determination
that any term or other provision is invalid, illegal or incapable of being
enforced, the parties hereto shall negotiate in good faith to modify this
Agreement so as to effect the original intent of the parties as closely as
possible in an acceptable manner to the end that the transactions
contemplated hereby are fulfilled to the extent possible.

          (b)  The Company and Parent agree that the Fee provided in Section
7.03(b) is fair and reasonable in the circumstances.  If a court of competent
jurisdiction shall nonetheless, by a final, non-appealable judgment,
determine that the amount of the Fee exceeds the maximum amount permitted by
law, then the amount of the Fee shall be reduced to the maximum amount


                                     -70-



permitted by law in the circumstances, as determined by such court of
competent jurisdiction.

guarantee hereof  constitute the entire agreement and supersede all prior
agreements and undertakings (other than the Confidentiality Agreements), both
written and oral, among the parties, or any of them, with respect to the
subject matters hereof and thereof, except as otherwise expressly provided
herein or therein.

          Section 8.09  Assignment.  This Agreement shall not be assigned by
operation of law or otherwise, except that all or any of the rights of Parent
and/or Merger Sub hereunder may be assigned to Guarantor or any direct or
indirect wholly-owned subsidiary of Guarantor, provided that no such
assignment shall relieve the assigning party of its obligations hereunder.

          Section 8.10  Parties in Interest.  This Agreement shall be binding
upon and inure solely to the benefit of each party hereto, and nothing in
this Agreement, express or implied, is intended to or shall confer upon any
other person any right, benefit or remedy of any nature whatsoever under or
by reason of this Agreement, including, without limitation, by way of
subrogation, other than Section 5.06 (which is intended to be for the benefit
of the Indemnified Parties and Covered Persons and may be enforced by such
Indemnified Parties and Covered Persons) and Section 7.03 (which contains
provisions intended to be for the benefit of Guarantor and may be enforced by
Guarantor).

          Section 8.11  Failure or Indulgence Not Waiver; Remedies
Cumulative.  No failure or delay on the part of any party hereto in the
exercise of any right hereunder shall impair such right or be construed to be
a waiver of, or acquiescence in, any breach of any representation, warranty
or agreement herein, nor shall any single or partial exercise of any such
right preclude any other or further exercise thereof or of any other right.
All rights and remedies existing under this Agreement are cumulative to, and
not exclusive of, any rights or remedies otherwise available.

          Section 8.12  Governing Law; Jurisdiction.  (a)  This Agreement

          Section 8.13  Counterparts.  This Agreement may be executed in two
or more counterparts, and by the different parties hereto in separate

but all of which taken together shall constitute one and the same agreement.

          Section 8.14  WAIVER OF JURY TRIAL.  EACH OF PARENT, MERGER SUB AND
THE COMPANY HEREBY IRREVOCABLY WAIVES (AND IN RESPECT OF ANY DISPUTE IN

                                   GUARANTEE


          Tyco International Ltd. ("Guarantor") irrevocably guarantees each
and every representation, warranty, covenant, agreement and other obligation
of Parent and Merger Sub, and/or any of their respective permitted assigns
(and where any such representation or warranty is made to the knowledge of
Parent or Merger Sub, such representation or warranty shall be deemed made to
the knowledge of Guarantor), and the full and timely performance of their
respective obligations under the provisions of the foregoing Agreement. This
is a guarantee of payment and performance, and not of collection, and
Guarantor acknowledges and agrees that this guarantee is full and
unconditional, and no release or extinguishment of Parent's and Merger Sub's
obligations or liabilities (other than in accordance with the terms of the
Agreement), whether by decree in any bankruptcy proceeding or otherwise,
shall affect the continuing validity and enforceability of this guarantee, as
well as any provision requiring or contemplating performance by Guarantor.

          Guarantor hereby waives, for the benefit of the Company, (i) any
right to require the Company as a condition of payment or performance by
Guarantor, to proceed against Parent or Merger Sub or pursue any other remedy
whatsoever and (ii) to the fullest extent permitted by law, any defenses or
benefits that may be derived from or afforded by law which limit the
liability of or exonerate guarantors or sureties, except to the extent that
any such defense is available to Parent or Merger Sub.

          Without limiting in any way the foregoing guarantee, Guarantor
covenants and agrees to take all actions to enable Parent and Merger Sub to
adhere to each provision of the Agreement which requires an act or omission
on the part of Guarantor or any of its subsidiaries to enable Parent or
Merger Sub to comply with its obligations under the Agreement.

          The provisions of Article VIII of the Agreement are incorporated
herein, mutatis mutandis, except that notices and other communications
hereunder to Guarantor shall be delivered to Tyco International Ltd., The
Zurich Centre, Second Floor, 90 Pitts Bay Road, Pembroke HM 08, Bermuda,
Attn:  Chief Corporate Counsel, Telecopy No. (441) 295-9647, Confirm No.
(441) 292-8674 (with a copy as provided therefor in Section 8.02(a)).



                                     -74-



          We understand that the Company is relying on this guarantee in
entering into the Agreement and may enforce this guarantee as if Guarantor
were a party thereto.

                                    TYCO INTERNATIONAL LTD.
