ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

On December 19, 1996, STERIS Corporation, through its newly-formed and
wholly-owned subsidiary Calgon Vestal, Inc., a Delaware corporation
(collectively, "STERIS"), completed the acquisition, from E.R. Squibb & Sons,
Inc. ("Squibb"), a Delaware corporation and a wholly-owned subsidiary of
Bristol-Myers Squibb Company, of the assets of the infection control and
contamination control businesses formerly carried on by Squibb through its
subsidiary, Calgon Vestal Laboratories, Inc. and the ConvaTec division of
Bristol-Myers Squibb (the "Acquired Business"). The assets acquired include two
manufacturing facilities in the St. Louis, Missouri area that STERIS intends to
use in the continuing conduct of the Acquired Business.

The purchase price for the Acquired Business, which was arrived at through
arms-length negotiations, was $75,000,000, part of which was paid from available
cash on hand and part of which was paid from a draw on STERIS's pre-existing
line of credit with a consortium of commercial banks.

Except as otherwise provided herein, for purposes of the Assumed Liabilities and
the Retained Liabilities, whenever reference is made to any liability or

States dollars ($75,000,000) in immediately available funds by wire transfer to
an account designated by the Seller at least two (2) business days prior to the
Closing Date.

                  2.4 ALLOCATION OF PURCHASE PRICE. The Seller and the Buyer
shall use all reasonable commercial efforts to agree, on or prior to the Closing
Date, to an allocation of the Purchase Price (together with the liabilities
assumed hereunder and other relevant items) among the Purchased Assets. Such
allocation will comply with the requirements of Section 1060 of the Code. The
Seller and the Buyer represent, warrant and agree that such allocation will be
determined through arm's-length negotiations. The Seller and the Buyer each
agrees that, to the extent permitted by applicable law, it will adopt and
utilize the amounts allocated to each asset or class of assets for purposes of
all federal, state and other Tax returns or reports of any nature filed by it
and that it will not voluntarily take any position inconsistent therewith upon
examination of any such Tax returns or reports, in any claim for refund, in any
litigation or otherwise with respect to such Tax returns or reports.
Notwithstanding any other provision of this Agreement, the foregoing agreement
shall survive the Closing Date without limitation.

                  2.5 FURTHER ASSURANCES; CONSENTS. (a) At the Closing and from
time to time after the Closing, (i) at the request of the Buyer and without

Buyer such certificates and other instruments of sale, conveyance, assignment
and transfer, and take such other action, as may reasonably be requested by the
Buyer more effectively to sell, convey, assign and transfer to and vest in the
Buyer or to put the Buyer in possession of the Purchased Assets, and (ii) at the
request of the Seller and without further consideration, the Buyer shall
promptly execute and deliver to the Seller such certificates and other
instruments of assumption, and take such other action, as may reasonably be
requested by the Seller more effectively to confirm and carry out the assumption
by the Buyer of the Assumed Liabilities.

                  (b) To the extent that any consents, waivers or approvals
necessary to convey items of Purchased Assets to the Buyer are not obtained
prior to the Closing, after the Closing the Seller shall use all reasonable
commercial efforts to: (i) obtain such consents, waivers and approvals (provided
that the Seller shall not be obligated to pay any consideration QUID PRO QUO for
any such consents, waivers and approvals) and (ii) pending receipt of such
consents, waivers or approvals (A) provide to the Buyer, at the reasonable
request of the Buyer, the benefits of any such Purchased Asset, and hold the
same in trust for the Buyer, and (B) enforce and perform, at the reasonable
request and expense of the Buyer, for the account of the Buyer, any rights or
obligations of the Seller arising from any such Purchased Asset against or in
respect of any third person, including the right to elect to terminate any
contract,


                                      -14-

arrangement or agreement in accordance with the terms thereof upon the advice of
the Buyer. The failure to obtain any consent, waiver or approval to any
agreement, contract or commitment which requires consent, waiver or approval
shall not be a condition to the Buyer's obligation to consummate the
transactions contemplated hereby.

                  (c) To the best knowledge of Seller, Seller is not aware of
any specific facts or events that would prevent the parties from obtaining the
material consents listed on Schedule 5.2 taken as a whole.

                  (d) The Buyer agrees to cooperate fully with the Seller as and
to the extent reasonably requested by the Seller in attempting to obtain any
consent that may be required from the landlord to assign the Warehouse Lease to
the Buyer, and will offer to agree with the landlord to an extension of the term
of the Warehouse Lease on the terms set forth in the letter attached as Schedule
2.5(d) or terms, the economic and operational effect of which is no less
favorable to the Buyer. If the consent of the landlord under the Warehouse Lease
is not obtained notwithstanding the Buyer's offer to agree as described above
and the Buyer is provided with notice of default or termination or similar
notice or is evicted from the Warehouse that is subject to the Warehouse Lease,
the Seller agrees to indemnify and hold harmless the Buyer for any reasonable
relocation cost that it may incur in connection with relocating to a new
facility from such Warehouse. If the Buyer extends the Warehouse Lease and
exercises the one-time early termination right set forth in the letter attached
as Schedule 2.5(d), the Seller shall reimburse the Buyer for the two-month rent
payment payable in connection with the exercise of such termination right.

practicable after the Closing Date but in any event within thirty (30) days
thereafter, the Buyer shall direct the preparation of, and deliver to the
Seller, a statement of Inventory as of the Closing Date (the "PRELIMINARY

accordance with the inventory valuation methods utilized by the Seller in
connection with the preparation of the Statement of Assets and Liabilities and

Buyer's independent public accountant on the Closing Date. The Buyer agrees that
Bristol-Myers Squibb and its representatives, including, without limitation,

the right to observe the performance of the physical inventory count
contemplated by this Section 3.1.

                  3.2 REVIEW OF PRELIMINARY INVENTORY STATEMENT. The Seller and
its independent public accountants may review the Preliminary Inventory
Statement and may make inquiry of the Buyer and its representatives, and the
Buyer will, and will cause the Acquired Business to, make available to the
Seller and its representatives, as reasonably requested by the Seller, all
books, records and other documents pertaining to the Inventory deemed necessary
or desirable by the Seller in connection with its review of the Preliminary
Inventory Statement and personnel responsible for performing the physical
inventory count. The Preliminary Inventory Statement shall be binding and
conclusive upon, and deemed accepted by, the Seller unless the Seller shall have
notified the Buyer in writing within thirty (30) days after receipt of the
Preliminary Inventory Statement of any objections thereto. A notice under this
Section 3.2 shall specify in reasonable detail the reasons for such dispute.

                  3.3 DISPUTES. (a) At the request of either party, any dispute
between the parties relating to the Preliminary Inventory Statement which cannot
be resolved by them within thirty (30) days after receipt by the Buyer of notice
of any objections to such Preliminary Inventory Statement pursuant to Section
3.2 shall be referred to the Disputes Auditor for final decision. If the
Disputes Auditor is unavailable, then the Buyer and the Seller shall select an
independent nationally recognized accounting firm to decide the matter. The
Disputes Auditor's decision on any matter referred to it shall be final and
binding on the Seller and the Buyer. The fee of the Disputes Auditor shall be
borne by the Seller and the Buyer in equal portions unless the Disputes Auditor
decides, based on its determination with respect to the reasonableness of the
respective positions of the parties, that the fee shall be borne in unequal
proportions.

                  (b) The parties shall, as promptly as practicable, submit
evidence in accordance with the procedures established by the Disputes Auditor,
and the Disputes Auditor shall decide the dispute in accordance therewith as
promptly as practicable.

                  3.4 FINAL INVENTORY STATEMENT. The Preliminary Inventory
Statement shall become final and binding on both parties upon the earliest of
(i) if no such notice has been given, the expiration of the period within which
the Seller may notify the Buyer of any objections thereto pursuant to Section
3.2, (ii) agreement by the Seller and the Buyer that such Preliminary Inventory
Statement, together with any modifications thereto agreed by the Seller and the
Buyer, shall be final and binding and (iii) the date on which the Disputes
Auditor shall issue its decision with respect to any dispute relating to such
Preliminary Inventory Statement. The Preliminary Inventory Statement, as
adjusted pursuant to any agreement between the


                                      -16-

parties or pursuant to the decision of the Disputes Auditor, when final and
binding on both parties, is herein referred to as the "FINAL INVENTORY
STATEMENT".

                  3.5 ADJUSTMENT TO THE PURCHASE PRICE. As soon as practicable
(but not more than five (5) business days) after the determination and delivery
of the Final Inventory Statement in accordance with Section 3.4, (i) the amount,
if any, by which the Inventory as reflected on the Final Inventory Statement is
less than the Inventory as of June 30, 1996 as reflected on the Statement of
Assets and Liabilities shall result in an immediate downward adjustment of the
Purchase Price equal to such amount, which amount shall be payable by the Seller
to the Buyer in immediately available funds and (ii) the amount, if any, by
which the Inventory as reflected on the Final Inventory Statement is greater
than the Inventory as of June 30, 1996 as reflected on the Statement of Assets
and Liabilities shall result in an immediate upward adjustment of the Purchase
Price equal to such amount, which amount shall be payable by the Buyer to the
Seller in immediately available funds.

                  3.6 INTEREST. All payments required to be made pursuant to
this Article 3 shall be with interest thereon at a rate of six percent (6%) per
annum and accruing from the Closing Date to the date of payment.

the Seller and CVL is a corporation duly incorporated, validly existing and in
good standing under the laws of the jurisdiction of its incorporation. Each of
the Seller and CVL is qualified to do business and in good standing in each
jurisdiction in which the nature of the Acquired Business or the ownership,
leasing or holding of the Purchased Assets requires it to be so qualified,
except to the extent that the failure to be so qualified or be in good standing,
either singly or in the aggregate, are not reasonably expected to have a
Material Adverse Effect. Each of the Seller and CVL has all requisite corporate
power and authority, and possesses all governmental franchises, licenses,
permits, authorizations and approvals necessary, to enable it to own, lease or
hold the Purchased Assets and to carry on the Acquired Business as presently
conducted, other than such franchises, licenses, permits, authorizations and
approvals the lack of which, either singly or in the aggregate, are not
reasonably expected to have a Material Adverse Effect.

into this Agreement and, subject to the approval of the Board of Directors of
Bristol-Myers Squibb, the Seller and CVL have the corporate power and authority
to consummate the transactions contemplated hereby. Subject to the approval of
the Board of Directors of Bristol-Myers Squibb, the execution and delivery of
this Agreement by the Seller and the consummation by the Seller and CVL of the
transactions contemplated hereby have been duly authorized by all requisite
corporate action on the part of the Seller and CVL and, subject to the approval
of the Board of Directors of Bristol-Myers Squibb, no other corporate action is
necessary to authorize this Agreement or to consummate the transactions
contemplated hereby. This Agreement has been duly executed and delivered by the
Seller and (assuming due authorization, execution and delivery hereof by the
Buyer) constitutes the valid and binding obligation of the Seller enforceable
against the Seller in accordance with its terms, subject to applicable
bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance and
other laws affecting creditors' rights generally from time to time in effect and
to general equitable principles (whether considered in a proceeding at law or in
equity).

                  5.2 NO VIOLATIONS. Except as disclosed on SCHEDULE 5.2, the
execution and delivery of this Agreement by the Seller do not, and the
consummation by the Seller and CVL of the


                                      -19-


<PAGE>   26



transactions contemplated hereby will not, conflict with, or result in any
violation of or default (with or without notice or lapse of time, or both)
under, or give rise to a right of termination under, or accelerate the
performance required by, or result in the creation of any Encumbrance upon any
of the Purchased Assets under, any provision of

                              (i) any law, statute, regulation or judicial or
         administrative decision applicable to the Seller, CVL or the
         Purchased Assets,

                  (b) Between the date hereof and the Closing Date, the Seller
shall use all commercially reasonable efforts to preserve the Acquired Business

employees of the Acquired Business and to preserve for the Buyer in all material
respects the relationships of the Acquired Business with its suppliers,
customers, distributors and others having business relations with the Acquired

                  (c) Between the date hereof and the Closing Date, the Seller

insuring the Acquired Business and its assets and business.

                  7.4  EMPLOYEE MATTERS.

                  (a) DEFINITIONS. The term "EMPLOYEES" shall mean all current
employees of the Acquired Business based in the United States (including those
on short-term disability or approved leave of absence), other than employees who
are covered by a collective bargaining agreement (the "UNION EMPLOYEES").

                  (b) EMPLOYMENT. (i) As of the Closing Date, the Buyer shall
offer employment to, and continue the employment of, all current Employees and
Union Employees at substantially the same salaries and wages (including bonus,
commission and sales incentive programs) and in comparable positions as those in
effect immediately prior to the Closing Date. The Buyer has no obligation under
this Agreement to offer employment to, or provide any other benefit to, any
employee of the Acquired Business who is not an Employee or a Union Employee.

                           (ii) After the Closing Date, all Employees, other
         than Union Employees, who become employees of the Buyer as of the
         Closing Date ("TRANSFERRED EMPLOYEES"), shall be treated in a similar
         manner as the other employees of the Buyer similarly situated with
         respect to the terms and conditions of employment. The Buyer agrees
         that all service of a Transferred Employee or a Union Employee who
         becomes an employee of the Buyer (a "TRANSFERRED UNION EMPLOYEE") with
         the Seller or credited by the Seller or Bristol-Myers Squibb shall be
         recognized by the Buyer under all employee benefit plans and
         arrangements of the Buyer or any of its subsidiaries in which the
         Transferred Employee or Transferred Union Employee becomes a
         participant for purposes of eligibility and vesting, to the same extent
         as if such service were rendered to the Buyer.

                  (c) UNION EMPLOYEE DEFINED BENEFIT PLAN. The Seller shall vest
the Transferred Union Employees who participate in the Hourly Plan in their
accrued benefit as of the Closing Date, but contingent on the Closing, under the
Hourly Plan. As of the Closing Date, the Buyer shall assume all assets and
liabilities


                                      -34-


<PAGE>   41



under the Hourly Plan. As soon as practicable after the Closing Date,
Bristol-Myers Squibb shall cause the assets of the Hourly Plan to be transferred
to a trust qualified under Section 501 of the Code established or designated by
the Buyer (the "BUYER HOURLY PLAN TRUST"), PROVIDED, HOWEVER, that prior to any
such transfer, the Buyer shall provide evidence reasonably satisfactory to
Bristol-Myers Squibb that the Buyer Hourly Plan Trust is qualified under Section
501 of the Code.

                  (d) TRANSFERRED EMPLOYEES ON SHORT TERM DISABILITY ON THE
CLOSING DATE. The Seller agrees that should any Transferred Employee who is on
short-term disability on the Closing Date continue to be permanently disabled
after the end of the applicable short-term disability period, then the Seller
shall provide long-term disability benefits to such disabled Transferred
Employee and the Buyer shall not be liable for any long-term disability benefits
to such disabled Transferred Employee.

                  (e) MAINTENANCE OF BENEFITS. The Buyer shall not be required
to provide (or to cause any of its Affiliates to provide) the Transferred
Employees with benefits that are similar to those provided by Seller pursuant to
the [Plans]. Notwithstanding the foregoing, the Buyer shall initially provide to
each Transferred Employee benefits (including, to the extent generally provided,
401(k), life, short-term disability, long-term disability, vacation, and
medical/dental) that are generally consistent with those provided by Buyer at
its similar operations as of the Closing Date.

                  (f) PARTICIPATION IN BENEFITS PLANS. The Buyer shall cause to
be waived any pre-existing condition limitation under its welfare plans that
might otherwise apply to a Transferred Employee, or shall take such other action
(such as self-insurance or direct reimbursement to affected Transferred
Employees) as may be necessary to provide the equivalent of such waiver to all
Transferred Employees.

                  (g) VACATION AND OTHER PAY. The Buyer shall assume the
obligations of the Seller and/or its Affiliates with respect to accrued but
untaken vacation pay earned by Transferred Employees as of the Closing, as
calculated under the vacation pay plan applicable to the Transferred Employees
as that plan was in effect on June 30, 1996, up to an aggregate number of
vacation days equal to the number of Transferred Employees multiplied by five.

                  (h) MULTIEMPLOYER PLAN. (i) After the Closing Date, the Buyer
agrees to tender contribution to the Central States, Southeast and Southwest
Areas Pension Fund (the "MULTIEMPLOYER PLAN") for substantially the same number
of contribution base units with respect to the operations of the Acquired
Business for which the Seller had an obligation to contribute (as defined in
Section 4212 of ERISA) to the Multiemployer Plan pursuant to the


                                      -35-


<PAGE>   42



collective bargaining agreement between the Seller and the Teamsters Local No.
688.

                           (ii) Unless the PBGC has issued a variance or
         exemption under Section 4204(c) of ERISA reasonably satisfactory to the
         Seller, the Buyer hereby agrees to provide to the Multiemployer Plan on
         or as soon as possible after the Closing Date, for a period of five
         consecutive plan years commencing after the Closing Date, a bond issued
         by a surety company that is an acceptable surety for purposes of
         Section 412 of ERISA. Such bond shall be in a form reasonably
         satisfactory to the Seller and shall be in an amount equal to the
         greater of (i) the average annual contribution that the Seller was
         required to make under the Multiemployer Plan with respect to the
         operations of the Acquired Business for the last plan year immediately
         preceding the plan year in which the Closing Date occurs or (ii) the
         annual contribution that the Seller has required to make under the
         Multiemployer Plan with respect to the operations of the Acquired
         Business for the last plan year immediately preceding the plan year in
         which the Closing Date occurs.

                           (iii) Unless the PBGC has issued a variance or
         exemption reasonably satisfactory to the Seller, if (i) the Buyer
         completely or partially withdraws from the Multiemployer Plan prior to
         the end of the fifth plan year beginning after the Closing Date, and
         (ii) the resulting liability of the Buyer with respect to the
         Multiemployer Plan is not paid, the Seller shall be secondarily liable
         for any withdrawal liability the Seller would have had to the
         Multiemployer Plan but for Section 4204 of ERISA. In the event the
         Seller becomes secondarily liable for withdrawal liability under the
         Multiemployer Plan, the Buyer shall reimburse the Seller for any and
         all costs and expenses incurred by the Seller with respect to such
         secondary liability.

                            (iv) The Seller will cooperate with the Buyer in the
         preparation and submission to the PBGC of a request for an individual
         variance or exemption from the surety bond requirements of Section 4204
         of ERISA.

                  (i) SEVERANCE. (i) The Buyer agrees to provide severance pay
which may be owing to any Transferred Employee whose employment is terminated by
the Buyer within six months after the Closing Date. Such severance pay
entitlements shall be determined in accordance with the severance policy of the
Acquired Business ("SEVERANCE POLICY") as in effect on June 30, 1996 applicable
to the Employees. For purposes of determining severance benefits, the Buyer
shall count (x) all service of a Transferred Employee that would have been
counted under the Severance Policy had such Transferred Employee been terminated
by


                                      -36-

the Seller on the Closing Date and (y) all service of such Transferred Employee
with the Buyer.

                           (ii) The Seller shall reimburse the Buyer with
         respect to all costs of providing severance pay to the first twenty one
         (21) Transferred Employees who become entitled to severance benefits
         under the Severance Policy by reason of being terminated within six
         months after the Closing Date.

                  7.5 FIRPTA CERTIFICATE. The Seller shall provide the Buyer, on
or before the Closing Date, with an affidavit in the form of EXHIBIT H to the
effect that Seller is not a "foreign person" within the meaning of Code Section
1445. If, on or before the Closing Date, the Buyer shall not have received such
affidavit, the Buyer may withhold from the Purchase Price payable at Closing to

under Section 1445 of the Code.

                  7.6 TITLE INSURANCE; ESTOPPEL CERTIFICATES. (a) After the date
hereof, the Seller shall use all reasonable commercial efforts to assist the

Owned Real Property, in amounts not less than the value of each such property,
as reasonably determined by the Buyer, insuring fee title thereto to be free and
clear of all Encumbrances, except Permitted Encumbrances. The cost of obtaining
such commitment and such Title Policy shall be borne equally by the Buyer and
the Seller. Each commitment and Title Policy shall be issued by a reputable
title insurance company or companies licensed in the state where the Owned Real
Property is located (any or each such company, the "TITLE COMPANY"). At the time
of delivery of such documents, the Seller shall use all reasonable commercial
efforts to deliver to the Buyer and the Title Company the usual and customary
affidavits, indemnification agreements or other documents as may be required in
order to omit from the Title Policy all exceptions other than Permitted
Encumbrances.

                  (b) At the time of delivery of the documents referred to in
Section 7.6(a), the Seller shall deliver such evidence as may be reasonably
required by the Title Company of the due authorization, execution and delivery
of this Agreement and the Transfer Documents. The Seller and the Buyer shall

transfer tax and other tax forms (including sales tax forms in connection with
its payment of sales taxes, if any) that are required to effectuate the
conveyance of the Properties.

                  (c) The Seller and the Buyer shall use all reasonable

and effect in accordance with its terms and has not been modified (except for
modifications set forth in the certificate), (ii) the date(s) to which rent and
other charges thereunder have been paid and (iii) that there is not a default
thereunder on the part of any party thereto.

                  7.7 LEASED VEHICLES. The Seller and the Buyer covenant and
agree to use all commercially reasonable efforts promptly after the Closing (but
in any event not more than ninety (90) days thereafter) to amend, or cause to be
amended, the automobile leases relating to the vehicles that are currently
leased by the Seller or its Affiliates for use by the Employees and listed on

                  7.12 COVENANT NOT TO COMPETE; NON-SOLICITATION BY SELLER. (a)
For the period ending on the third anniversary of the Closing Date, neither the
Seller nor any of its Affiliates, shall engage, in any geographical area in

HOWEVER, that nothing contained herein shall restrict the Seller or its
Affiliates from manufacturing, selling or distributing (i) the Retained Patient
Skin Care Products, (ii) Hexifoam, to the extent sold in the South Pacific
region, (iii) any other products currently manufactured, sold or distributed by

marketed or sold by the Seller or any of its Affiliates to consumers and (v) any

foregoing prohibitions (the "COMPETING OPERATIONS") so long as (x) the annual
revenues attributable to the Competing Operations do not exceed the lesser of
$15 million or twenty five percent (25%) of the annual revenues of such business
or (y) if they do, the acquiring entity divests the Competing Operations as soon
as practicable, but not later than eighteen (18) months, after such acquisition.

                  (b) (i) For the period ending on the third anniversary of the
Closing Date, the Seller and its Affiliates will not, directly or indirectly,
solicit, encourage, entice or induce any person who is listed on SCHEDULE 7.12
(a "RESTRICTED EMPLOYEE") to terminate his or her employment with the Buyer, nor
may the Seller or any of its Affiliates employ any such employee during the
first year of such three year period, PROVIDED that the Seller will not be
precluded from hiring any such employee who (i) initiates discussions regarding
such employment without any direct or indirect solicitation by the Seller or its
Affiliates, (ii) responds to any public advertisement placed by the Seller or
its Affiliates in any publication of general circulation or (iii) has been

<PAGE>   47



         person who is a non-union employee of the Acquired Business at the date
         hereof to terminate his or her employment with the Buyer, nor may

         ConvaTec and such employee.

                  (c) Each of the Seller and ConvaTec agrees that damages at law
would be an insufficient remedy to the Buyer in the event of a breach by the
Seller or any of its Affiliates or by Convatec of Section 7.12(a) and Section
7.12(b), respectively, and that the Buyer shall be entitled to injunctive relief
or other equitable remedies in the event of any such breach.

                  (d) If any of the provisions of Section 7.12(a) are held to be
unenforceable because of the scope, term or area of their applicability, then
the court making such determination shall modify such scope, term or area or all
of them to the extent necessary to render Section 7.12(a) enforceable under
applicable law, and such provisions shall then be enforced in such modified
form.

                  7.13 CONFIDENTIALITY AGREEMENTS. On the Closing Date, the
Seller shall cause Bristol-Myers Squibb to assign to the Buyer its rights under
all confidentiality agreements (other than the Confidentiality Agreement)
entered into by Bristol-Myers Squibb with prospective bidders in connection with
the proposed sale of the Acquired Business to the extent the rights relate to
confidential information of the Acquired Business (it being understood that the
Seller and its Affiliates shall retain all other rights under such
confidentiality agreements). At the Closing, the Seller will provide the Buyer
with a copy of each such confidentiality agreement. Notwithstanding the
foregoing, the Seller shall not assign, or provide copies of, any such
confidentiality agreement if doing so would result in a breach thereof.

                  7.14 CHANGE OF NAME. The Seller will take all necessary
corporate or other action as soon as practicable, and in any event within three
(3) months after the Closing, to change the name of CVL to a name which does not
use the "Calgon" or "Vestal" name or any substantially similar name.

                  7.15 USE OF CERTAIN NAMES. (a) The Buyer agrees that the
Seller may, for up to twelve (12) months after the Closing Date, use packaging,

distribution of the Retained Patient Skin Care Products; PROVIDED, HOWEVER, that
the Seller (i) shall use all reasonable efforts in its procurement of such
materials after the Closing to procure materials which do not include any such
names, and to overprint, sticker or otherwise identify on such materials in such
a way as to either obliterate such names or clearly indicate that neither the
Seller nor any of its Affiliates is affiliated with the Acquired Business and
(ii) shall not use any such names after the Closing in any manner or for any
purpose different from the use of such names by the Seller or its Affiliates
during the ninety (90) day period preceding the Closing.

                  (b) The Seller agrees that the Acquired Business may, for up
to twelve (12) months after the Closing Date, use packaging, labels, package
inserts, catalogs, brochures, handbooks and similar materials which contain the
name "ConvaTec" or variations thereof (including logos), as necessary after the
Closing and until the supplies thereof included in the Purchased Assets have
been exhausted; PROVIDED, HOWEVER, that the Buyer (i) shall use all reasonable
efforts in its procurement of such materials after the Closing to procure
materials which do not include any such names, and to overprint, sticker or
otherwise identify on such materials in such a way as to either obliterate such
names or clearly indicate that neither the Seller nor any of its Affiliates is
affiliated with the Acquired Business and (ii) shall not use any such names
after the Closing in any manner or for any purpose different from the use of
such names by the Seller or its Affiliates during the ninety (90) day period
preceding the Closing.

                  (c) Notwithstanding anything in this Section 7.15 to the
contrary, in no event shall the Buyer, any Affiliate of the Buyer or the
Acquired Business have the right under any circumstance to use for any purpose
the names "Bristol-Myers Squibb Company," "Bristol-Myers Squibb," "BMS," "B-MS,"
"E.R. Squibb & Sons, Inc.," "E.R. Squibb" or any variations thereof.

                  7.16 CONSENTS; TRANSFER OF PERMITS. (a) Except as provided in
Section 7.16(b): (i) No representation, warranty or covenant of the Seller
contained in this Agreement shall be breached or deemed breached, and no
condition shall be deemed not satisfied, as a result of (A) the failure to
obtain any consent, waiver or approval required under any agreement, contract or
commitments set forth on Schedule 5.2, or (B) any lawsuit, action, claim,
proceeding or investigation commenced or threatened by or on behalf of any
Persons arising out of or relating to the failure to obtain any such consent,
waiver or approval or any default under or acceleration or termination of any
agreement, contract or commitment.

                  (ii) The Seller agrees to cooperate with the Buyer after the
Closing, upon the request of the Buyer, in any reasonable manner, in connection
with the transfer of the Permits


                                      -42-


<PAGE>   49



to the Buyer; PROVIDED, HOWEVER, that such cooperation shall not include any
requirement that the Seller, CVL or any of their respective Affiliates expend
any money, commence or participate in any litigation or offer or grant any
accommodation (financial or otherwise) to any third party.

                  (b) Section 7.16(a) shall not apply if and to the extent the
Seller fails to fulfill its obligations under Section 2.5(b).

                  7.17 MIXED PRODUCT CONTRACTS; DISTRIBUTORS. (a) Promptly after
the date hereof, the Seller shall provide to the Buyer, upon the Buyer's
reasonable request, reasonable assistance in order to assign to the Buyer all
rights, and for the Buyer to assume all obligations, under the Mixed Product
Contracts as they relate to products or business of the Acquired Business. Each
of the Buyer and the Seller acknowledges and agrees the other party hereto has
significant interests in the Mixed Product Contracts with respect to such
party's respective products and business and therefore each of the Buyer and the
Seller agrees that it will not take any action or fail to take any action that
could reasonably be expected to jeopardize or otherwise harm such other party's
or such other party's Affiliate's interest in any Mixed Product Contract or the
relationship between such other party or such other party's Affiliates and any
other party to such Mixed Product Contracts. Each of the Buyer and the Seller
and their respective Affiliates will use all reasonable commercial efforts to
facilitate the transition of the Mixed Product Contract as contemplated by and
in accordance with the terms of the Transition Services Agreement.

                  (b) Prior to the assignment and assumption of any Mixed
Product Contract as contemplated by Section 7.17(a), whether by means of the
execution of a new agreement by the Buyer and the other party to the Mixed
Product Contract or the execution of an assignment and assumption agreement, the
Buyer shall honor the prices and other terms set forth in such Mixed Product
Contract during the currently remaining term of such Mixed Product Contract
(including, to the extent applicable, delivering products of the Acquired
Business to a party placing purchase orders for such products after the Closing
Date on the terms contemplated by the applicable Mixed Product Contract).

                  (c) After the Closing Date, each of the Buyer and the Seller
shall provide to the other party, upon such other party's reasonable request,
reasonable assistance in order to facilitate the continuation of relationships
of such other party's business with the distributors of its products (the
"DISTRIBUTORS"). Each of the Buyer and the Seller acknowledges and agrees that
the other party and its respective Affiliates have significant interests in
their relationships with Distributors as such Distributors deal in the products
of the other party and such party's Affiliates and therefore each of the Buyer
and the Seller agrees that it will not take any action or fail to take any


                                      -43-


<PAGE>   50



action that could reasonably be expected to jeopardize or otherwise harm the
other party's or such other party's Affiliate's relationships with the
Distributors.

                  7.18 DISCLAIMER OF OTHER REPRESENTATIONS AND WARRANTIES; BEST
KNOWLEDGE; DISCLOSURE. (a) Whenever a representation or warranty made by the
Seller herein refers to the knowledge or expectation of the Seller, such
knowledge or expectation shall be deemed to consist only of the actual knowledge
or expectation of any of those persons listed on SCHEDULE 7.18. The Seller has
not undertaken, nor shall the Seller have any duty to undertake, any inquiry or
investigation concerning any matter as to which a representation or warranty is
made as to the Seller's knowledge or expectation except for consultation with
the individuals listed on SCHEDULE 7.18.

                  (b) Notwithstanding anything to the contrary contained in this

shall be deemed to be disclosed on all Schedules. Certain information set forth
in the Schedules is included solely for informational purposes and may not be
required to be disclosed pursuant to this Agreement. The disclosure of any
information shall not be deemed to constitute an acknowledgment that such
information is required to be disclosed in connection with the representations
and warranties made by the Seller in this Agreement or that it is material, nor
shall such information be deemed to establish a standard of materiality.

                  10.3 INDEMNIFICATION OF SELLER AND ITS AFFILIATES. Subject to
Section 10.5, the Buyer agrees to defend, indemnify and hold harmless the Seller
and the Seller's Affiliates, and their respective successors and assigns
(individually, a "SELLER INDEMNITEE", and collectively, the "SELLER
INDEMNITEES"), against and in respect of:

                  (a) any and all Damages suffered or incurred by any Seller
Indemnitee which is caused by, or resulting or arising from any failure by the

                  10.4 NOTICE AND OPPORTUNITY TO DEFEND. If any action, suit,
proceeding, claim, liability, demand or assessment shall be asserted against any
Buyer Indemnitee or any Seller Indemnitee (the "INDEMNITEE") in respect of which
such Indemnitee proposes to demand indemnification, such Indemnitee shall notify
the party obligated to provide indemnification pursuant to Section 10.2 or 10.3
(the "INDEMNIFYING PARTY") thereof within a reasonable period of time after
assertion thereof; PROVIDED, FURTHER, that the failure to so notify the
Indemnifying Party shall not affect the Indemnitee's right to indemnification
hereunder unless and only to the extent the Indemnifying Party's interests are
actually prejudiced thereby. Subject to rights of or duties to any insurer or
other third Person having liability therefor, the Indemnifying Party shall have
the right within ten (10) days after receipt of such notice to assume the
control of the defense, compromise or settlement of any such action, suit,
proceeding, claim, liability, demand or assessment, including, at its own
expense, employment of counsel; PROVIDED, HOWEVER, that if the Indemnifying
Party shall have exercised its right to assume such control, the Indemnitee (i)
may, in its sole discretion and at its own expense, employ separate counsel to
represent it in any such matter, and in such event counsel selected by the
Indemnifying Party shall be required to cooperate with such counsel of the
Indemnitee in such defense, compromise or settlement for the purpose of
informing and sharing information with such Indemnitee and (ii) will, at its own
expense, make available to the Indemnifying Party those employees of the
Indemnitee or any Affiliate of the Indemnitee (including, but not limited to, in
the case of the Buyer, the Acquired Business) whose assistance, testimony or
presence is desirable to assist the Indemnifying Party in evaluating and in
defending any such action, suit, proceeding, claim, liability, demand or
assessment; PROVIDED, HOWEVER, that any such access shall be conducted in such a
manner as not to interfere unreasonably with


                                      -48-


<PAGE>   55



the operations of the businesses of the Indemnitee and its Affiliates
(including, but not limited to, in the case of the Buyer, the Acquired
Business). The Indemnifying Party shall not compromise or settle any such
action, suit, proceeding, claim, liability or assessment without the consent of
the Indemnitee, which consent shall not be unreasonably withheld or delayed, if
such compromise or settlement could adversely impact the Indemnitee.

                  10.5 CERTAIN LIMITATIONS. The liability of the Seller or the
Buyer, as applicable, for claims under this Agreement shall be limited by the
following:

                  (a) At any time after the Survival Date, (i) the Seller shall
have no further obligations under this Article 10 for breaches of
representations and warranties of the Seller, except for Damages with respect to
which the Buyer Indemnitee has given the Seller written notice prior to such
date in accordance with Section 10.4 and (ii) the Buyer shall have no further
obligations under this Article 10 for breaches of representations and warranties
of the Buyer, except for Damages with respect to which the Seller Indemnitee has
given the Buyer written notice prior to such date in accordance with Section
10.4.

                  (b) The amount of Damages otherwise recoverable under this
Article 10 shall be (i) reduced to the extent to which any Federal, state, local
or foreign tax liabilities of the Seller Indemnitee or the Buyer Indemnitee, as
applicable, or any of its Affiliates is decreased by reason of any Damage in
respect of which such Seller Indemnitee or Buyer Indemnitee, as applicable,
shall be entitled to indemnity under this Agreement and (ii) increased to the
extent to which any Federal, state, local or foreign tax liabilities are
incurred by the Seller Indemnitee or the Buyer Indemnitee, as applicable, or any
of its Affiliates as a result of the receipt of the indemnity so that, after any
such decrease or increase, the position of the indemnified party is the same on
an after tax basis as it would have been had there been neither any tax benefit
nor any tax cost associated with either the Damage or the indemnity.

                  (c) The amount of Damages otherwise recoverable under this
Article 10 shall be reduced to the extent the party seeking indemnification
receives insurance proceeds with respect to the matter for which indemnification
is sought.

                  (d) Notwithstanding anything to the contrary herein, any claim
by a Buyer Indemnitee against the Seller for breach of the representations and
warranties of the Seller under this Agreement shall be payable by the Seller
only in the event that the accumulated amount of the claims in respect of the
Seller's obligations to indemnify under this Agreement shall exceed
U.S.$2,000,000 in the aggregate (the "SELLER INDEMNIFICATION THRESHOLD");
PROVIDED, HOWEVER, that at such time as the aggregate amount of claims in
respect of the indemnity


                                      -49-


<PAGE>   56



obligations of such party shall exceed the Seller Indemnification Threshold, the
Seller shall thereafter be liable only, subject to Section 10.5(e), for Damages
suffered or incurred by Buyer Indemnitees in excess of U.S.$2,000,000, it being
the intention of the parties that the initial U.S.$2,000,000 of claims excluded
under the Seller Indemnification Threshold would not be recoverable against the
Seller but would be borne by the Buyer.

                  (e) Notwithstanding anything to the contrary herein, in no
event shall the maximum aggregate liability of the Seller with respect to
Damages suffered or incurred by Buyer Indemnitees hereunder exceed
U.S.$37,500,000.

                  (f) Notwithstanding anything to the contrary herein, any claim
by a Seller Indemnitee against the Buyer for breaches of the representations and
warranties of the Buyer under this Agreement shall be payable by the Buyer only
in the event and to the extent that the accumulated amount of the claims in
respect of the Buyer's obligations to indemnify under this Agreement shall
exceed U.S.$2,000,000 in the aggregate (the "BUYER INDEMNIFICATION THRESHOLD");
PROVIDED, HOWEVER, that at such time as the aggregate amount of claims in
respect of the indemnity obligations of such party shall exceed the Buyer
Indemnification Threshold, the Buyer shall thereafter be liable, subject to
Section 10.5(g), for Damages suffered or incurred by Seller Indemnitees in
excess of U.S.$2,000,000, it being the intention of the parties that the initial
U.S.$2,000,000 of claims excluded under the Buyer Indemnification Threshold
would not be recoverable against the Buyer but would be borne by the Seller.

                  (g) Notwithstanding anything to the contrary herein, in no
event shall the maximum aggregate liability of the Buyer with respect to Damages
suffered or incurred by Seller Indemnitees hereunder exceed U.S.$37,500,000.

                  10.6 PRODUCT LIABILITY CLAIMS. Subject to the limitations set
forth in Sections 10.5(b), (c) and (e), the Seller agrees to indemnify and hold
harmless the Buyer against and in respect of fifty percent (50%) of the Assumed
Liabilities described in Section 2.2(a)(iii).

                  10.7 ENVIRONMENTAL CLAIMS. (a) Subject to the limitations set
forth in Sections 10.5(b), (c) and (e) and in this Section 10.7, the Seller
agrees to indemnify and hold harmless the Buyer against and in respect of fifty
percent (50%) of the Assumed Liabilities described in Section 2.2(a)(iv)
(excluding any costs and expenses incurred by the Buyer in connection with any
environmental investigation or assessment) (the "ASSUMED ENVIRONMENTAL
LIABILITIES") to the extent (and only to the extent) such liabilities and
obligations are actually incurred by the Buyer and directly arise out of or
directly relate to any violation of any Environmental Law, to investigate,
remediate, remove, treat, contain or prevent the escape or migration of
Hazardous Materials on, in, under, at or from the


                                      -50-

Properties in order to protect the environment. The Buyer agrees to keep the
Seller generally informed as to its plan to incur expenses covered by this
Section 10.7.

                  (b) Anything in this Agreement to the contrary
notwithstanding, the Seller's obligation to indemnify the Buyer for the Assumed
Environmental Liabilities pursuant to this Agreement will not extend to any cost
incurred after the third anniversary of the Closing Date and will accrue if and
only if:

                           (i) the aggregate amount of the Assumed Environmental
         Liabilities exceeds U.S.$500,000, it being understood and agreed to by
         each of the parties hereto that such U.S.$500,000 shall be borne solely
         by the Buyer; and

                           (ii) the Buyer undertakes (at its sole cost and
         expense) the environmental investigation or assessment of the
         Properties giving rise to such Assumed Environmental Liabilities within
         one (1) year of the Closing Date and the Buyer notifies the Seller in
         writing of any potential Assumed Environmental Liabilities that are
         identified in connection with such investigation or assessment within
         such one-year period.

                  10.8 REMEDIES. Except in the case of fraud by the breaching
party, indemnification in accordance with the provisions of this Agreement shall
be the sole and exclusive remedy of the Buyer and the Seller for any Damages
suffered or incurred by Buyer Indemnitees or Damages suffered or incurred by
Seller Indemnitees, respectively, including, but not limited to, any and all
breaches of or inaccuracies in any of the respective representations or
warranties, covenants, agreements or other obligations of the Seller and the
Buyer set forth in this Agreement or in any other agreement or instrument
contemplated thereby.

written instrument executed by the parties or their respective successors or
assigns.

intended the right to enforce such Article, as applicable), nothing in this

                  12.11 SEVERABILITY; ENFORCEMENT. The invalidity of any portion

extent permitted by law, and each party hereby consents and agrees that such
scope may be judicially modified accordingly in any proceeding brought to
enforce such restriction.

                  12.12 WAIVER. Any of the conditions to Closing set forth in
this Agreement may be waived at any time prior to or at the Closing hereunder by
the party entitled to the benefit thereof. The failure of any party hereto to
enforce at any time any of the provisions of this Agreement shall in no way be
construed to be a waiver of any such provision, nor in any way to affect the
validity of this Agreement or any part hereof or the right of such party
thereafter to enforce each and every such provision. No waiver of any breach of
or non-compliance with this Agreement shall be held to be a waiver of any other
or subsequent breach or non-compliance.
