         (A) the numerator of which is equal to the number of days elapsed since
         the first day of the calendar quarter in which the Launch Date occurs

                  (ii)     In the event that (A) Purchaser settles the
         litigation matter set forth as item 1 on Schedule 5.5 and such
         settlement permits, or does not prohibit, commercial sales to
         unaffiliated third parties by Barr Laboratories, Inc. ("BARR") or any
         of its Affiliates of a Competing Drug and (B) Barr or any of its
         Affiliates commences such commercial sales, (I) Purchaser's obligation
         to make the Additional Payments will terminate in accordance with the
         last sentence of Section 2.6(b)(i) and (II) for a period of ten days
         thereafter, Purchaser and Pfizer shall negotiate in good faith whether
         or not Purchaser shall provide to Pfizer (as agent on behalf of the
         Asset Selling Corporations) further consideration for the sale and
         transfer of the Purchased Assets, in lieu of the continuation of the
         Additional Payments and, if so, the amount of such consideration and
         such terms and conditions as may be reasonably acceptable to Purchaser
         and Pfizer. If, by the end of such ten day period, Purchaser and Pfizer
         are unable to reach an agreement on whether and how much further
         consideration shall be paid and the terms and conditions thereof,
         Purchaser and Pfizer shall refer such matter to an independent third
         party valuation specialist (such as a reputable investment bank)
         mutually acceptable to Purchaser and Pfizer. Such valuation specialist
         shall make a determination with respect to whether and how much further
         consideration shall be paid and the terms and conditions thereof within
         15 days after its engagement by Purchaser and Pfizer. In making such
         determination, such valuation specialist shall consider the value to
         Pfizer of the remaining Additional Payments that it would have
         otherwise likely received in the absence of the settlement, the terms
         of Purchaser's settlement and such other matters as the parties and
         such valuation specialist deem relevant. Such determination shall be
         delivered in writing to Purchaser and Pfizer within such 15 day period
         and shall be final and binding on, and nonappealable by, Purchaser and
         Pfizer. Purchaser and Pfizer shall each pay one-half the costs incurred
         in connection with the engagement of such valuation specialist.

                  (iii)    If (A) a Competing Drug (other than a Competing Drug
         commercially sold to unaffiliated third parties by Barr or any of its
         Affiliates as permitted, or not prohibited, by any settlement of the
         litigation matter set forth as item 1 on Schedule 5.5) is withdrawn
         from the market in the United States (the date of such withdrawal, the
         "WITHDRAWAL DATE") and (B) the Exclusivity Period has not expired,
         Purchaser shall resume payment of the Additional Payments commencing on
         the last Business Day of the calendar quarter following the first full
         calendar quarter after the Withdrawal Date occurs until the expiration
         of the Exclusivity Period in accordance with the first sentence of
         Section 2.6(b)(i). All other Additional Payments made pursuant to this
         Section 2.6(b)(iii) shall be made in accordance with the first sentence
         of Section 2.6(b)(i) (excluding the parenthetical relating to the
         aggregate total payment), unless Purchaser's obligation to make such
         Additional Payments is terminated pursuant to and in accordance with
         the last sentence of Section 2.6(b)(i); it being understood that the
         date of re-commencement of commercial sales to unaffiliated third
         parties of a withdrawn Competing Drug shall be deemed to be a "Launch
         Date" for purposes

                                       14
<PAGE>

         of Section 2.6(b)(i). For the avoidance of doubt, this Section
         2.6(b)(iii) shall in no way affect the rights and obligations of the
         parties under Section 2.6(b)(ii), including the respective rights and
         obligations of the parties upon a withdrawal from the market in the
         United States of a Competing Drug commercially sold to unaffiliated
         third parties by Barr or any of its Affiliates as permitted, or not
         prohibited, by any settlement of the litigation matter set forth as
         item 1 on Schedule 5.5.

                  Section 2.7 Allocation of the Purchase Price. The parties
shall negotiate in good faith and agree upon an allocation of the Purchase Price
(a) among each of the Asset Selling Corporations and (b) between tangible and
intangible Purchased Assets (collectively, the "ALLOCATION"). Pfizer and
Purchaser agree not to take a position on any income tax return, before any
Governmental Authority or in any judicial proceeding that is inconsistent with
the Allocation. The Additional Payments shall be allocated in the same manner as
the Purchase Price.

                  Section 2.8 Risk of Loss. Until the Closing, any loss of or
damage to the Purchased Assets from fire, casualty or any other occurrence shall
be the sole responsibility of Pfizer or its Affiliates, as the case may be. At
the Closing, title to the Purchased Assets shall be transferred to Purchaser,
and Purchaser shall thereafter bear all risks of loss associated with the
Purchased Assets.

                  Section 2.9 Adjustment of the Purchase Price.

                  (a)      Promptly after the execution of this Agreement,
Pfizer shall engage IMS Health Incorporated ("IMS") to determine the Months of
Supply of the Product that was held by Pfizer's or its Affiliates' wholesale and
chain customers, as of January 31, 2003 (the "CALCULATION DATE"). Pfizer and
Purchaser shall each pay one-half of all the costs incurred in connection with
the engagement of IMS. "MONTHS OF SUPPLY" shall be determined as set forth on
Schedule 2.9. Pfizer shall request that IMS deliver to each of Pfizer and
Purchaser, within 30 days of the Closing Date, a notice (the "SUPPLY NOTICE")
setting forth the Months of Supply as of the Calculation Date for the Product.
The determination of IMS of Months of Supply as set forth on the Supply Notice
shall be final, conclusive and binding on the parties hereto.

                  (b)      The Purchase Price shall be adjusted in accordance
with the formula set forth on Schedule 2.9(b).

                  (c)      In addition, if the Applicable Average Daily Sales
exceeds the Historic Average Daily Sales, the Purchase Price shall be reduced by
an amount equal to such excess multiplied by the Historic Gross Profit
Percentage multiplied by the number of days in the period from February 1, 2003
to and including the Closing Date (the "DAILY SALES ADJUSTMENT AMOUNT"). As
promptly as practicable after the Closing, Pfizer shall deliver a certificate to
Purchaser setting forth in reasonable detail the Applicable Average Daily Sales
and the Daily Sales Adjustment Amount, if any, calculated pursuant to this
Section 2.9(c). If any adjustment to the Purchase Price is

                                       15
<PAGE>

required pursuant to this Section 2.9(c) as set forth in such certificate
delivered by Pfizer, Pfizer shall pay to Purchaser the Daily Sales Adjustment
Amount by wire transfer in immediately available funds to an account specified
in writing by Purchaser within five Business Days after delivery of such
certificate.

                  (d)      The Purchase Price as it may be adjusted pursuant to
Sections 2.9(b) and (c) shall be referred to herein as the "ADJUSTED PURCHASE
PRICE".

in accordance with its terms, except as enforcement may be limited by
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
creditors' rights generally or by general principles of equity (regardless of
whether enforcement is sought in a proceeding in equity or law).

performance by each of Purchaser and Parent of this Agreement and, in the case
of Purchaser, of the Ancillary Agreements and, subject to the receipt of the

the aggregate, a material adverse effect on the ability of Purchaser or Parent,
as the case may be, to perform its obligations under this Agreement and, in the
case of Purchaser, the Ancillary Agreements (a "PURCHASER MATERIAL ADVERSE
EFFECT") or would not reasonably be expected to materially delay the
consummation of the transactions contemplated hereby.

                  Section 6.5 Governmental Consents. Except as set forth in
Section 4.1(b), the execution and delivery by each of Purchaser and Parent of

inspections and investigations and the representations and warranties made to
Purchaser by Pfizer in Article V, Purchaser is relinquishing any right to any

SHAREHOLDER APPROVAL") is the only vote of the holders of any class or series of
the capital stock and/or any class or share in the capital of Purchaser or
Parent necessary to approve this Agreement and the transactions contemplated
hereby.

this Agreement and (ii) Purchaser or Parent, as the case may be, shall take
promptly, in the event that any permanent or preliminary injunction or other
order is entered or becomes reasonably foreseeable to be entered in any
proceeding relating to the enforcement of any applicable Competition Laws that
would make consummation of the acquisition of the Purchased Assets or the other
transactions contemplated hereby in accordance with the terms of this Agreement
unlawful or that would prevent or delay consummation of the acquisition of the
Purchased Assets or the other transactions contemplated by this Agreement, any
and all steps (including the appeal thereof or the posting of a bond) necessary
to vacate, modify or suspend such injunction or order so as to permit such
consummation on a schedule as close as possible to that contemplated by this

to be employed by Purchaser and (v) not make any counteroffer to any Femhrt
Employee who receives a written offer of employment from Purchaser.

Product.

                  (b)      Within ten Business Days after the Closing, Pfizer
and Purchaser jointly shall notify the counterparties to the Managed Care

is a party shall be terminated solely with respect to the Product.

                  Section 7.9 Post-Closing Cooperation.

<PAGE>

                  (c)      Each of the parties hereto shall from time to time
after the Closing, without additional consideration, execute and deliver such
further instruments and take such other action as may be reasonably requested by
the other party to make effective the transactions contemplated by this
Agreement and the Ancillary Agreements. With respect to all documents,
information and other materials included in the Purchased Assets, in addition to
paper and other tangible copies, Pfizer shall, upon Purchaser's reasonable
request, also provide to Purchaser electronic copies of such documents,
information and other materials, provided that Pfizer or any of its Affiliates
or their respective agents have electronic copies thereof.

                  (d)      Each party shall reimburse the other for reasonable
out-of-pocket costs and expenses incurred in assisting the other pursuant to
this Section 7.9. Neither party shall be required by this Section 7.9 to take
any action that would unreasonably interfere with the conduct of its business or
unreasonably disrupt its normal operations.

Pfizer agrees that for a period of ten years following the Closing Date, it
shall, and it shall cause its Affiliates, agents and representatives to, keep
confidential any and all information, in any form or medium, relating solely to

"Confidential Information" does not include any information that (i) at the time
of disclosure or thereafter is generally available in the public domain (other

representatives) or (ii) is required to be disclosed under applicable Law or
judicial process.

                  (b)      The parties hereto agree that a breach of this
Section 7.10 would cause irreparable damage for which no adequate remedy at law
would exist and damages would be difficult to determine and that Purchaser shall
be entitled to an injunction or injunctions to prevent breaches of this Section
7.10 and to enforce specifically the terms and provisions of this Section 7.10,
in addition to any other remedy at law or equity.

shall agree or resolve to) withdraw or modify in a manner adverse to Pfizer or
propose publicly to withdraw or modify in a manner adverse to Pfizer the
recommendation by such Board of Directors or any such committee of this
Agreement or the transactions contemplated hereby, unless such Board of
Directors or a committee thereof determines in good faith (after consultation
with outside counsel) that the failure to take such action would result in a
breach of its fiduciary duties under applicable Law (any such action taken in
accordance with this Section 7.11 being referred to herein as a "PARENT ADVERSE
RECOMMENDATION CHANGE").

                  (i)      As promptly as practicable following the date of this
         Agreement, Parent shall prepare and mail the circular of Parent (the
         "PARENT CIRCULAR") to be sent to the shareholders of Parent in
         connection with obtaining the Parent Shareholder Approval at the
         Shareholders' Meeting. Parent shall respond promptly to any comments of
         the UK Listing Authority (the "UKLA") with respect to the Parent
         Circular. In any event, Parent shall use its reasonable best efforts to
         obtain the clearance of the UKLA on or before March 7, 2003. Pfizer
         covenants and agrees that it shall provide such reasonable assistance
         in the preparation of the Parent Circular as may be reasonably
         requested by Parent. The Parent Circular shall comply in all material
         respects with the requirements of the UKLA Listing Rules as published
         by the Financial Services Authority, the articles of association and
         memorandum of association of Parent and all other applicable Laws.

                  (ii)     Parent shall, as promptly as practicable after the
         receipt of the clearance of the UKLA, establish a record date (which
         will be as promptly as reasonably practicable following the receipt of
         the clearance of the UKLA) for, duly call, give notice of, convene and
         hold a meeting of its shareholders, which meeting Parent shall cause to
         occur on the earlier of (A) the 20th day following the mailing of the
         Parent Circular and (B) the sixth Business Day prior to the Termination
         Date (the "SHAREHOLDERS' MEETING"), for the purpose of obtaining the
         Parent Shareholder Approval; provided, however, that if Parent is
         unable to obtain a quorum of its shareholders at such time, Parent may
         extend the date of the Shareholders' Meeting by no more than five
         Business Days and Parent shall use its best efforts during such five
         Business Day period to obtain such a quorum as soon as practicable. The
         notice of such Shareholders' Meeting shall state that a resolution to
         approve this Agreement and the transactions contemplated hereby will be
         considered at the Shareholders' Meeting. Subject to Section 7.11(a),
         Parent shall, through its Board of Directors or any committee thereof,
         recommend to its shareholders that they approve this Agreement and the
         transactions contemplated hereby and shall include such recommendation
         in the Parent Circular.

                  Section 7.12 Transfer of Regulatory Approvals.

                  (a)      Assignment. Promptly after the Closing, Pfizer and
Purchaser shall work together to transfer and assign all Product Registrations
to Purchaser at such times and in such a manner as is reasonably acceptable to
Purchaser. In the event that Purchaser assigns any Product Registrations to an
Affiliate of Purchaser or to a third party, Purchaser shall remain liable for
the performance of its obligations under this Agreement.

                  (b)      Reporting Obligations. Upon the transfer and
assignment of each of the Product Registrations to Purchaser, as provided in
Section 7.12(a), and thereafter,

                                       32
<PAGE>

Purchaser shall be solely responsible for making all reports to the appropriate
Governmental Authorities as are required in connection with such Product
Registrations assigned to Purchaser and for conducting all pharmacovigilance
activities in connection with such Product Registrations. In order for the
parties hereto to comply with their respective responsibilities under this
Section 7.12 and otherwise relating to the reporting of adverse drug
experiences, to the extent any party receives any information regarding an
adverse drug experience relating to the use of any of the Products, such party
shall promptly provide the other party with such information in accordance with
adverse drug experience procedures that shall be mutually agreed upon by Pfizer
and Purchaser after the signing of this Agreement, but in any event no later
than one month following the Closing Date.

                  Section 7.13 Certain Patents. Immediately following the
Closing, Purchaser shall grant to Pfizer or its designated Affiliate a
non-exclusive, perpetual, royalty-free, worldwide license to use the Patents set
forth as item 2 on Schedule 2.1(a)(i), it being understood that Pfizer or such
Affiliate shall not use such Patents in connection with any hormone replacement
therapy products.

                                  ARTICLE VIII

                                 INDEMNIFICATION

                  Section 8.1 Indemnification by Pfizer.

                  (a)      Subject to the provisions of this Article VIII,
Pfizer agrees to defend, indemnify and hold harmless Parent, Purchaser and their
respective Affiliates, and their respective directors, officers, agents,
employees, successors and assigns, from and against any and all claims, actions,
causes of action, judgments, awards, Liabilities, losses, costs (including
reasonable attorney's fees) or damages (collectively, a "LOSS" or, the "LOSSES")
claimed or arising from (i) any Retained Liability, (ii) any breach by Pfizer of
any of its covenants or agreements contained in this Agreement or (iii) any
breach of any representation or warranty of Pfizer contained in this Agreement,
the Transitional Services Agreement or the Transitional Intellectual Property
License Agreement (it being agreed that solely for the purposes of such right to
indemnification, such representations and warranties shall be deemed not
qualified by any reference therein to materiality (including Material Adverse
Effect)).

                  (b)      Purchaser and Parent acknowledge and agree that
Pfizer shall not have any Liability under any provision of this Agreement for
any Loss to the extent that such Loss relates to action taken by Purchaser,
Parent or their Affiliates (other than action taken by Pfizer in breach of this
Agreement) after the Closing Date. Each of Parent and Purchaser shall take, and
shall cause their respective Affiliates to take, all reasonable steps to
mitigate any Loss upon becoming aware of any event which would reasonably be
expected to, or does, give rise thereto, including incurring costs only to the
extent reasonably necessary to remedy the breach which gives rise to the Loss.

                  Section 8.2 Indemnification by Parent.

                  (a)      Subject to the provisions of this Article VIII,
Parent agrees to defend, indemnify and hold harmless Pfizer and its Affiliates,
and their respective directors, officers, agents, employees, successors and
assigns, from and against any and all Loss claimed or arising from (i) any
Assumed Liability, (ii) any breach by Purchaser or Parent of any of its
covenants or agreements in this Agreement, (iii) any breach of any
representation or warranty of Purchaser or Parent contained in this Agreement
or, in the case of Purchaser, the Transitional Services Agreement or the
Transitional Intellectual Property License Agreement or (iv) events occurring on
or after the Closing Date in connection with the Products or the Purchased
Assets, including the use, ownership or possession of the Purchased Assets from
and after the Closing Date.

                  (b)      Pfizer shall take, and cause its Affiliates to take,
all reasonable steps to mitigate any Loss upon becoming aware of any event which
would reasonably be expected to, or does, give rise thereto, including incurring
costs only to the extent reasonably necessary to remedy the breach which gives
rise to the Loss.

                  Section 8.3 Notice of Claims. If any of the Persons to be
indemnified under this Article VIII (the "INDEMNIFIED PARTY") has suffered or
incurred any Loss, the Indemnified Party shall so notify the party from whom
indemnification is sought (the "INDEMNIFYING PARTY") promptly in writing
describing such Loss, the amount or estimated amount thereof, if known or
reasonably capable of estimation, and the method of computation of such Loss,
all with reasonable particularity and containing a reference to the provisions
of this Agreement or any other agreement or instrument delivered pursuant hereto
in respect of which such Loss shall have occurred. If any action at Law or suit
in equity is instituted by or against a third party with respect to which the
Indemnified Party intends to claim any Liability as a Loss under this Article
VIII, the Indemnified Party shall promptly notify the Indemnifying Party of such
action or suit and tender to the Indemnifying Party the defense of such action
or suit. A failure by the Indemnified Party to give notice and to tender the
defense of the action or suit in a timely manner pursuant to this Section 8.3
shall not limit the obligation of the Indemnifying Party under this Article
VIII, except (i) to the extent such Indemnifying Party is materially prejudiced
thereby, (ii) to the extent expenses that are incurred during the period in
which notice was not provided shall not be deemed a Loss and (iii) as provided
by Section 8.5.

                  Section 8.4 Third Party Claims.

                  (a)      The Indemnifying Party under this Article VIII shall
have the right, but not the obligation, to conduct and control, through counsel
of its choosing, any third party claim, action, suit or proceeding (a "THIRD
PARTY CLAIM"), and the Indemnifying Party may compromise or settle the same,
provided that the Indemnifying Party shall give the Indemnified Party advance
notice of any proposed compromise or settlement, provided further that the
Indemnifying Party shall not compromise or settle any Third Party Claim without
the approval of the Indemnified Party if such compromise or

                                       34
<PAGE>

settlement imposes any obligations on the Indemnified Party, such approval not
to be unreasonably withheld. No Indemnified Party may compromise or settle any
Third Party Claim for which it is seeking indemnification hereunder without the
consent of the Indemnifying Party. The Indemnifying Party shall permit the
Indemnified Party to participate in, but not control, the defense of any such
action or suit through counsel chosen by the Indemnified Party, provided that
the fees and expenses of such counsel shall be borne by the Indemnified Party.
If the Indemnifying Party elects not to control or conduct the defense or
prosecution of a Third Party Claim, the Indemnifying Party nevertheless shall
have the right to participate in the defense or prosecution of any Third Party
Claim and, at its own expense, to employ counsel of its own choosing for such
purpose.

                  (b)      The parties hereto shall cooperate in the defense or
prosecution of any Third Party Claim, with such cooperation to include (i) the
retention of and the provision to the Indemnifying Party of records and
information that are reasonably relevant to such Third Party Claim and (ii) the
making available of employees on a mutually convenient basis for providing
additional information and explanation of any material provided hereunder.

                  Section 8.5 Expiration Notwithstanding anything in this
Agreement to the contrary, if the Closing shall have occurred, all covenants,
agreements, representations and warranties made herein shall survive the
Closing. Notwithstanding the foregoing, all representations and warranties made
herein (except for the last two sentences of Section 5.10 and Section 5.11), and
all indemnification obligations under Sections 8.1 and 8.2 with respect to any
such representation or warranty, shall terminate and expire on, and no action or
proceeding seeking damages or other relief for breach of any thereof or for any
misrepresentation or inaccuracy with respect thereto shall be commenced after,
the expiration of 18 months following the Closing Date, unless prior to such
date a claim for indemnification with respect thereto shall have been made, with
reasonable specificity, by written notice given under Section 8.3.

                  Section 8.6 Certain Limitations. Notwithstanding the other
provisions of this Article VIII, Pfizer shall not have any indemnification
obligations for Losses under Section 8.1(a)(iii), (i) for any individual item
where the Loss relating thereto is less than $50,000 and (ii) in respect of each
individual item where the Loss relating thereto is equal to or greater than
$50,000, (A) unless the aggregate amount of all such Losses exceeds 1% of the
Adjusted Purchase Price, in which event Pfizer shall be required to pay all
amounts of such Losses (from the first dollar of such Losses), and (B) only up
to a maximum amount of 35% of the Adjusted Purchase Price; provided, however,
that the foregoing limitations shall not apply to breaches of any of the
representations and warranties contained in the last two sentences of Section
5.10 and Section 5.11.

                  Section 8.7 Losses Net of Insurance, Etc.. The amount of any
Loss for which indemnification is provided under Section 8.1 or 8.2 shall be net
of (i) any amounts recovered by the Indemnified Party pursuant to any
indemnification by or indemnification agreement with any third party (any such
third party, a "COLLATERAL

                                       35
<PAGE>

SOURCE") and (ii) an amount equal to the present value of the tax benefit, if
any, attributable to such Loss. Indemnification under this Article VIII shall
not be available unless the Indemnified Party first uses all commercially
reasonable efforts to seek recovery from all Collateral Sources. The
Indemnifying Party may require an Indemnified Party to assign the rights to seek
recovery pursuant to the preceding sentence; provided, however, that the
Indemnifying Party will then be responsible for pursuing such claim at its own
expense. If the amount to be netted hereunder from any payment required under
Section 8.1 or 8.2 is determined after payment by the Indemnifying Party of any
amount otherwise required to be paid to an Indemnified Party to this Article
VIII, the Indemnified Party shall repay to the Indemnifying Party, promptly
after such determination, any amount that the Indemnifying Party would not have
had to pay pursuant to this Article VIII had such determination been made at the
time of such payment.

                  Section 8.8 Sole Remedy/Waiver. Subject to Sections 7.3(d),
7.10(b) and 9.2, the parties hereto acknowledge and agree that the remedies
provided for in this Agreement shall be the parties' sole and exclusive remedy
with respect to the subject matter of this Agreement, other than claims for
injunctive relief. In furtherance of the foregoing, the parties hereby waive, to
the fullest extent permitted by applicable Law, any and all other rights, claims
and causes of action (including rights of contributions, if any) known or
unknown, foreseen or unforeseen, which exist or may arise in the future, other
than claims for injunctive relief, that it may have against Pfizer or any of its
Affiliates or Purchaser or any of its Affiliates, as the case may be, arising
under or based upon any federal, state or local Law.

                  Section 8.9 No Consequential Damages. NOTWITHSTANDING ANYTHING
TO THE CONTRARY CONTAINED HEREIN, NO PARTY TO THIS AGREEMENT SHALL BE LIABLE TO
OR OTHERWISE RESPONSIBLE TO ANY OTHER PARTY HERETO OR ANY AFFILIATE OF ANY OTHER
PARTY HERETO FOR CONSEQUENTIAL, INCIDENTAL OR PUNITIVE DAMAGES OR FOR DIMINUTION
IN VALUE OR LOST PROFITS THAT ARISE OUT OF OR RELATE TO A BREACH OF THE
REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT (OTHER THAN THE
REPRESENTATIONS AND WARRANTIES CONTAINED IN THE LAST TWO SENTENCES OF SECTION
5.10 AND SECTION 5.11), THE TRANSITIONAL SERVICES AGREEMENT AND THE TRANSITIONAL
INTELLECTUAL PROPERTY LICENSE AGREEMENT.

                                   ARTICLE IX

                                   TERMINATION

                  Section 9.1 Termination. This Agreement may be terminated at
any time prior to the Closing:

                  (a)      by mutual written agreement among Purchaser, Parent
and Pfizer;

                                       36
<PAGE>

                  (b)      by Purchaser, Parent or Pfizer, by giving written
notice of such termination to the other party, if the Closing shall not have
occurred on or prior to April 30, 2003 (the "TERMINATION DATE") (unless the
failure to consummate the Closing by such date (i) shall be due to the failure
of the party seeking to terminate this Agreement to have fulfilled any of its
obligations under this Agreement or (ii) is due to the continuance of a waiting
period or lack of an approval required under or an injunction or equivalent
thereof entered based upon any Competition Laws, in which event Purchaser and
Parent may not rely upon this Section 9.1(b) to terminate this Agreement until
nine months from the date of this Agreement);

                  (c)      by Purchaser, Parent or Pfizer, if any court of
competent jurisdiction or other competent Governmental Authority shall have
issued a Governmental Order or taken any other action permanently restraining,
enjoining or otherwise prohibiting the transactions contemplated by this
Agreement and such Governmental Order or other action shall have become final
and nonappealable;

                  (d)      by Purchaser, Parent or Pfizer, if the Parent
Shareholder Approval shall not have been obtained at the Shareholders' Meeting
duly convened therefor or at any adjournment or postponement thereof;

                  (e)      by Pfizer, in the event that a Parent Adverse
Recommendation Change shall have occurred; or

                  (f)      by Pfizer, if Parent shall have failed to perform any
of its material covenants and agreements set forth in Section 7.11.

                  Section 9.2 Effect of Termination.

                  (a)      In the event of the termination of this Agreement in
accordance with Section 9.1, this Agreement shall thereafter become void and
have no effect, and no party hereto shall have any Liability to the other party
hereto or their respective Affiliates, directors, officers or employees, except
for the obligations of the parties hereto contained in this Section 9.2 and
Sections 7.1(b), 10.1, 10.7, 10.8, 10.9 and 10.11, and except that nothing
herein will relieve any party from Liability for any material breach of any
covenant set forth in this Agreement prior to such termination.

                  (b)      If this Agreement is terminated pursuant to Section
9.1(e) or (f) and both (i) Pfizer shall have performed in all material respects
its agreements and obligations contained in this Agreement required to be
performed by it at or before such Parent Adverse Recommendation Change (in the
case of Section 9.1(e)) or such failure (in the case of Section 9.1(f)), as the
case may be, and (ii) the representations and warranties of Pfizer contained in
this Agreement (A) that are qualified as to materiality or by reference to
Material Adverse Effect are true and correct and (B) that are not so qualified
are true and correct in all material respects, in each case as of the date of
this Agreement and as of the date of such Parent Adverse Recommendation Change
(in the case of Section 9.1(e)) or such failure (in the case of Section 9.1(f)),
as the case may be,

                                       37
<PAGE>

except to the extent such representations and warranties expressly relate to a
particular date (in which case, on and as of such particular date), then Parent
shall pay Pfizer a fee equal to $2,700,000 (the "TERMINATION FEE") by wire
transfer of immediately available funds to an account designated by Pfizer
within two Business Days after such termination.

                  (c)      If this Agreement is terminated pursuant to Section
9.1(d) and Pfizer shall have performed in all material respects its agreements
and obligations contained in this Agreement required to be performed by it at or
before such termination, then Parent shall reimburse Pfizer for all the
reasonable fees and expenses, not in excess of $112,500, of Pfizer's outside
vendors (including its attorneys) incurred since October 17, 2002 in connection
with the evaluation and pursuit of the transactions contemplated by this
Agreement (the "PFIZER REIMBURSABLE FEES") by wire transfer of immediately
available funds to an account designated by Pfizer within two Business Days
after such termination.

                  (d)      If (i) this Agreement is terminated by Parent and
Purchaser pursuant to Section 9.1(b) or (c) as a consequence of and based upon
the failure of the condition to the Closing set forth in Section 4.1(b) and both
(A) the conditions to the Closing set forth in Sections 4.1(c) and 4.2(e) shall
have been satisfied at the time of such termination and (B) Parent and Purchaser
shall have performed in all material respects their respective agreements and
obligations contained in this Agreement required to be performed by them at or
before such termination or (ii) the provisions of Section 10.16 are effected,
then Pfizer shall reimburse Parent and Purchaser for all of their reasonable
fees and expenses, not in excess of $250,000, of their outside vendors
(including their attorneys) in connection with their evaluation and pursuit of
the transactions contemplated by this Agreement (the "PARENT REIMBURSABLE FEES")
by wire transfer of immediately available funds to an account designated by
Parent within two Business Days after such termination.

                  (e)      Parent acknowledges and agrees that the agreements
contained in Sections 9.2(b) and (c) are an integral part of the transactions
contemplated by this Agreement, and that, without these agreements, Pfizer would
not enter into this Agreement; accordingly, if Parent fails promptly to pay the
amount due pursuant to either Section 9.2(b) or (c), and, in order to obtain
such payment, Pfizer commences a suit that results in a judgment against Parent
for the Termination Fee or the Pfizer Reimbursable Fees, as the case may be,
Parent shall pay to Pfizer its costs and expenses (including attorneys' fees and
expenses) in connection with such suit, together with interest on the amount of
the Termination Fee or the Pfizer Reimbursable Fees, as the case may be, from
the date such payment was required to be made until the date of the payment at
the prime rate of Citibank, N.A. in effect on the date such payment was required
to be made.

                  (f)      Pfizer acknowledges and agrees that the agreements
contained in Section 9.2(d) are an integral part of the transactions
contemplated by this Agreement, and that, without these agreements, Parent and
Purchaser would not enter into this Agreement; accordingly, if Pfizer fails
promptly to pay the amount due pursuant to

                                       38
<PAGE>

Section 9.2(d), and, in order to obtain such payment, Parent and Purchaser
commence a suit that results in a judgment against Pfizer for the Parent
Reimbursable Fees, Pfizer shall pay to Parent its costs and expenses (including
attorneys' fees and expenses) in connection with such suit, together with
interest on the amount of the Parent Reimbursable Fees, from the date such
payment was required to be made until the date of the payment at the prime rate
of Citibank, N.A. in effect on the date such payment was required to be made.

                  (g)      In the event this Agreement shall be terminated and
at such time any party is in material breach of or default under any term or
provision hereof, such termination shall be without prejudice to, and shall not
affect, any and all rights to damages that the other party may have hereunder or
otherwise under applicable Law. The damages recoverable by the non-defaulting
party shall include all attorneys' fees reasonably incurred by such party in
connection with the transactions contemplated hereby.

                  (h)      If this Agreement is terminated in accordance with
Section 9.1 or the provisions of Section 10.16 are effected, Purchaser agrees
that the prohibition in the Confidentiality Agreement restricting Purchaser's
ability to solicit any employee of Pfizer or any of its Affiliates to join the
employ of Purchaser or any of its Affiliates shall be extended to a period of
two years from the date of this Agreement.

                  Section 10.2 Amendment; Waiver. Any provision of this
Agreement may be amended or waived if, and only if, such amendment or waiver is
in writing and signed, in the case of an amendment, by Parent, Purchaser and
Pfizer, or in the case of a waiver, by the party against whom the waiver is to
be effective. No failure or delay by any party in exercising any right, power or
privilege hereunder shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege.

                  Section 10.3 Assignment. No party to this Agreement may assign
any of its rights or obligations under this Agreement without the prior written
consent of the other party hereto, except that Purchaser may without such
consent assign its rights to purchase the Purchased Assets or its obligation to
assume the Assumed Liabilities hereunder to one or more of its Affiliates or to
any successor to all or substantially all of its pharmaceuticals business;
provided, however, that no such assignment by Purchaser shall relieve Purchaser
of any of its obligations hereunder.

                  Section 10.4 Entire Agreement. This Agreement (including all
Schedules and Exhibits) contains the entire agreement between the parties hereto
with

                                       40
<PAGE>

respect to the subject matter hereof and supersedes all prior agreements and
understandings, oral or written, with respect to such matters, except for the
Confidentiality Agreement which will remain in full force and effect for the
term provided for therein and other than any written agreement of the parties
that expressly provides that it is not superseded by this Agreement.

                  Section 10.5 Fulfillment of Obligations. Any obligation of any
party to any other party under this Agreement, which obligation is performed,
satisfied or fulfilled by an Affiliate of such party, shall be deemed to have
been performed, satisfied or fulfilled by such party.

                  Section 10.6 Parties in Interest. Except as provided in
Article VIII, this Agreement shall inure to the benefit of and be binding upon
the parties hereto and their respective successors and permitted assigns.
Nothing in this Agreement, express or implied, is intended to confer upon any
Person other than Parent, Purchaser, Pfizer or their respective successors or
permitted assigns, any rights or remedies under or by reason of this Agreement.

                  Section 10.7 Public Disclosure. Notwithstanding anything
herein to the contrary, each of the parties to this Agreement hereby agrees with
the other parties hereto that, except as may be required to comply with the
requirements of any applicable Laws, and the rules and regulations of each stock
exchange upon which the securities of either of the parties is listed, no press
release or similar public announcement or communication shall, if prior to the
Closing, be made or caused to be made concerning the execution or performance of
this Agreement unless the parties shall have consulted in advance with respect
thereto.

                  Section 10.8 Return of Information. If for any reason
whatsoever the transactions contemplated by this Agreement are not consummated
(including by reason of Section 10.16), Purchaser or Parent, as applicable,
shall promptly return to Pfizer, or an officer of Purchaser or Parent, as
applicable, shall certify on behalf of Purchaser or Parent, as applicable, to
the destruction of, all books and records furnished by Pfizer, any other Seller
Corporation or any of their respective Affiliates, agents, employees, or
representatives (including all copies, summaries and abstracts, if any, thereof)
in accordance with the terms of the Confidentiality Agreement.

                  Section 10.9 Expenses. Except as otherwise expressly provided
in this Agreement, whether or not the transactions contemplated by this
Agreement are consummated, all costs and expenses incurred in connection with
this Agreement and the transactions contemplated hereby shall be borne by the
party incurring such expenses. Notwithstanding the foregoing, all Taxes
(including any value added taxes but excluding any income taxes) and recording
fees, in each case relating to the transfer of the Purchased Assets, shall be
paid by Purchaser.

                  Section 10.10 Schedules. The disclosure of any matter in any
one Schedule shall be deemed to be a disclosure for all purposes of this
Agreement to the

                                       41
<PAGE>

extent that the relevance of such matters to other Sections or other applicable
Schedules is reasonably apparent to a reader on its face, but shall expressly
not be deemed to constitute an admission by Pfizer, Purchaser or Parent, or to
otherwise imply, that any such matter is material for the purposes of this
Agreement.

                  Section 10.11 Governing Law; Jurisdiction.

                  (a)      This Agreement shall be governed by and construed in
accordance with the Laws of the State of New York, regardless of the Laws that
might otherwise govern applicable principles of conflicts of Laws thereof.

                  (b)      With respect to any suit, action or proceeding
relating to this Agreement (each, a "PROCEEDING"), each party hereto irrevocably
(i) agrees and consents to be subject to the jurisdiction of the United States
District Court for the Southern District of New York or any New York State court
sitting in New York, New York, United States of America and (ii) waives any
objection which it may have at any time to the laying of venue of any Proceeding
brought in any such court, waives any claim that such Proceeding has been
brought in an inconvenient forum and further waives the right to object, with
respect to such Proceeding, that such court does not have any jurisdiction over
such party. Purchaser and Parent hereby irrevocably designate, appoint and
empower CT Corporation System, with offices located at 111 Eighth Avenue, 13th
Floor, New York, New York 10011, as their designee, appointee and agent to
receive, accept and acknowledge for and on their behalf service of any legal
process, summons notices and documents which may be served in any such
Proceeding. If for any reason CT Corporation System is unable or unwilling to
continue to act as such designee, appointee and agent, Purchaser and Parent
agree to immediately appoint a successor designee, appointee and agent in New
York, New York, United States of America reasonably acceptable to Pfizer.

                  Section 10.12 Counterparts. This Agreement may be executed in
one or more counterparts, each of which shall be deemed an original, and all of
which shall constitute one and the same agreement.

                  Section 10.13 Headings. The heading references herein and the
table of contents hereto are for convenience purposes only, do not constitute a
part of this Agreement and shall not be deemed to limit or affect any of the
provisions hereof.

                  Section 10.14 Severability. The provisions of this Agreement
shall be deemed severable and the invalidity or unenforceability of any
provision shall not affect the validity or enforceability of the other
provisions hereof. If any provision of this Agreement, or the application
thereof to any Person or any circumstance, is invalid or unenforceable, (a) a
suitable and equitable provision shall be substituted therefor in order to carry
out, so far as may be valid and enforceable, the intent and purpose of such
invalid or unenforceable provision and (b) the remainder of this Agreement and
the application of such provision to other Persons or circumstances shall not be
affected by such invalidity or unenforceability, nor shall such invalidity or
unenforceability affect the

                                       42
<PAGE>

validity or enforceability of such provision, or the application thereof, in any
other jurisdiction.

                  Section 10.15 Guarantee of Parent. Parent guarantees the full
and timely payment and performance of Purchaser's and any of its other
Affiliates' covenants, agreements, obligations, Liabilities, representations and
warranties under this Agreement and the Ancillary Agreements.

                  Section 10.16 Unwind. If the Closing shall have occurred prior
to final FTC approval of the FTC Consent Order, and Pfizer thereafter receives
notice from the FTC that Purchaser is not an acceptable purchaser of the
Purchased Assets or that the consummation of the transactions contemplated by
this Agreement and the Ancillary Agreements does not constitute an acceptable
manner of divestiture, then the parties shall immediately rescind the
transactions consummated at the Closing, and this Agreement and the Ancillary
Agreements shall be automatically terminated upon such rescission (other than
Section 9.2 of this Agreement and the Sections referenced therein). In
connection with such rescission, Pfizer shall refund the Purchase Price (or
Adjusted Purchase Price, as the case may be, in either case without interest) to
Purchaser, Purchaser shall return all the Purchased Assets in its or its
Affiliates' possession or control to Pfizer, and the parties shall take such
other actions as may be necessary in order to return each party to the
respective position it occupied immediately prior to the Closing (it being
understood, however, that Purchaser shall retain any profits and bear any losses
in respect of its ownership of the Purchased Assets).
