desires to sell to Purchaser, and Purchaser desires to purchase from Seller, the
Acquired Assets (Section 8.2(b) identifies the sections of this Agreement in

      liabilities arising out of or relating to any product liability, breach of
      warranty or similar claim for injury to person or property, regardless of

      otherwise related to the Products (including all Proceedings relating to
      any such liabilities);

            (ii) except to the extent set forth in Section 1.3(c)(iii) (A) and

<PAGE>   9
            (b) Purchaser and Seller hereby agree to reimburse one another,
dollar for dollar, in the event that any of their or their respective
Affiliate's customers offset, against accounts payable by such customer to
Seller or Purchaser or their respective Affiliates, the cost of any Products
returned by such customer, in each case which are the responsibility of the
other party hereto pursuant to this Section 1.3. Seller and Purchaser agree to,
and to cause their respective Affiliates to, provide notice to one another of
any such offset for which such party or its Affiliate is entitled to be
reimbursed pursuant to this Section 1.3(b). Payment shall be made promptly
following receipt of notice of any such offset by a customer (together with
supporting documentation). Seller and Purchaser shall, and Seller shall cause
its Affiliates to, cooperate to ensure that a customer does not offset returns
of any Product against both Seller (or any of its Affiliates) and Purchaser.

            (c) Notwithstanding any other provision of this Agreement or any
Related Instrument, Purchaser shall not assume any Excluded Liability, each of
which shall be retained and paid, performed and discharged when due by Seller
and its Affiliates. The term "Excluded Liability" shall mean:

            (i) account payables and liabilities, obligations and commitments of
      Seller or any of its Affiliates for materials and services with respect to
      the manufacture of any Products;

            (ii) all liabilities arising out of or relating to any product
      liability, breach of warranty or similar claim for injury to person or
      property, regardless of when asserted, which resulted from the use or
      misuse of Products manufactured by or on behalf of Seller and shipped to a
      third party prior to the Closing (the "Shipped Products") or otherwise
      related to the Shipped Products (including all Proceedings relating to any
      such liabilities);

            (iii) all liabilities arising out of or relating to (A) the return
      after the Closing Date of any Shipped Products which returns are a result
      of adulteration or misbranding (within the meaning of the FDA Act or the
      rules and regulations promulgated thereunder) by Seller, (B) the return
      during the six (6) month period after the Closing Date of any Products
      that on the date of return have an expiration date not earlier than three
      (3) months and not later than six (6) months after such date of return and
      (C) rebates related to any Shipped Products which were shipped to a third
      party prior to December 31, 1999;

            (iv) any Tax payable with respect to any business, asset, property
      or operation of Seller or any member of any affiliated group of which
      Seller is a member (including any Taxes relating to or arising out of the
      operation of the Businesses) for any Pre-Closing Tax Period, other than
      any Tax for which Purchaser is responsible pursuant to Section 4.6
      ("Excluded Tax Liability");

            (v) any liability, obligation or commitment of Seller or any of its
      Affiliates arising out of or relating to any Excluded Asset;
<PAGE>   10
            (vi) any liability, obligation or commitment of any kind arising out
      of or relating to employment, compensation or benefits (including
      severance) for the present or future employees of Seller or any of its
      Affiliates for all employment relating to the Businesses; or

            (vii) except to the extent specifically provided in Section 1.3(a)
      (i), (ii), (iii), (iv), (v) and (vi), all other liabilities, obligations
      and commitments of whatever kind and nature, primary or secondary, direct
      or indirect, absolute or contingent, known or unknown, whether or not
      accrued, arising out of or relating to, directly or indirectly, the
      Businesses or the Acquired Assets (including the Products) but only to the
      extent related to any period prior to the Closing Date.

            (d) Each of Purchaser's and Seller's obligations under this Section
1.3 will not be subject to offset or reduction by reason of any actual or
alleged breach of any representation, warranty or covenant contained in this
Agreement or any Related Instrument or any right or alleged right to
indemnification hereunder.

            (e) For the avoidance of doubt, if there is any conflict between the
terms of this Section 1.3 and the terms of either of the Supply Agreements with
respect to any liabilities arising out of, or related to, directly or
indirectly, Products (as such term is defined in the applicable Supply
Agreement) sold by Seller or its Affiliates to Purchaser pursuant to such Supply
Agreement, the terms of such Supply Agreement shall govern.

to Closing the relevant account numbers of the accounts to which such transfers
should be made) ; (ii) a duly executed Trademark License Agreement; (iii) a duly
executed Assignment of Patent; (iv) a duly executed Assignment of Trademarks;

<PAGE>   11

            Section 1.5 Risk of Loss. Until the Closing, any loss of or damage
to the Acquired Assets from fire, casualty or any other occurrence shall be the
sole responsibility of Seller or its Affiliates, as applicable. On the Closing

Assets and be solely responsible for procuring adequate insurance to protect the
Acquired Assets against any such loss.

            Section 1.6 Purchase Price Adjustment. (a) Promptly after execution
of this Agreement, Seller shall retain IMS Health Incorporated ("IMS") to
determine the Months of Supply of each Product Line that were held by Seller's
or its Affiliates' wholesale customers as of the end of the month immediately
preceding the month in which the Closing Date occurs (the "Calculation Date").
"Months of Supply" shall be calculated by IMS using the methodology set forth on
Schedule 1.6. For purposes of this Section 1.6, "Product Line" means each of (i)
all Ovcon 35 and Ovcon 50 Products determined in the aggregate (the "Ovcon
Product Line") and (ii) all Estrace Cream Products determined in the aggregate
(the "Estrace Product Line"). Seller shall request that IMS deliver to each of
Seller and Purchaser, as soon as practicable after the Closing Date, a notice
(the "IMS Notice") setting forth the Months of Supply as of the Calculation Date
for each Product Line.

            (b) If the Months of Supply of the Ovcon Product Line, as set forth
in the IMS notice, exceeds 2.1, then Seller shall pay to Purchaser in cash,
within 10 business days of receipt of the IMS Notice, the product of (i) the
Months of Supply of the Ovcon Product Line as of the Calculation Date minus 2.1
and (ii) $2,463,000. If the Months of Supply of the Estrace Product Line, as set
forth in the IMS Notice, exceeds 2.4, then Seller shall pay to Purchaser in
cash, within 10 business days of receipt of the IMS Notice, the product of (A)
the Months of Supply of Estrace Product Line as of the Calculation Date minus
2.4 and (B) $1,565,000. For the avoidance of doubt, to the extent that any
amounts payable by Seller pursuant to this clause (b) are less than zero,
Purchaser shall have no obligation to pay the absolute value of such amounts to
Seller.

            (c) Notwithstanding anything to the contrary set forth in this
Agreement, the foregoing shall be Purchaser's sole and exclusive remedy with
respect to Seller's (and its Affiliates') sales practices related to incentives
or other inducements to purchase Products offered, or volume of the Products
sold, to Seller's (or such Affiliates') customers, in each case, prior to the
Closing Date. Purchaser shall not be entitled to recovery under Article VII for
any Losses arising from any breaches of representations and warranties or
breaches of covenants in this Agreement or in any Related Instrument relating to
such sales practices or volume of sales.

available to the public and that copies of this Agreement and the Related
Instruments shall not be publicly filed or otherwise made available to the

becomes available to the public other than as a result of a breach of this
Section 4.3(c). The covenant set forth in this Section 4.3(c) shall terminate
five (5) years after the later of the termination of the Estrace Supply
Agreement and the termination of the Ovcon Supply Agreement.

            Section 4.4 Best Efforts. (a) On the terms and subject to the
conditions of this Agreement, and subject to Section 3.6 with respect to
Purchaser's obligation to obtain funds, each party shall use its best efforts to
cause the Closing to occur, including taking all reasonable actions necessary to
comply promptly with all legal requirements that may be imposed on it or any of
its Affiliates with respect to the Closing. Without limiting the foregoing or
the provisions set forth in Section 4.5, and subject to Section 3.6 with respect
to Purchaser's obligation to obtain funds, Purchaser and Seller shall use their
respective best efforts to cause the Closing to occur on or prior to February
15, 2000.

supply the FTC and the DOJ such supplemental information requested, if any, in
connection with the transactions contemplated hereby pursuant to the HSR Act.
Any supplemental information shall be in substantial compliance with the
requirements of the HSR Act. Each of Purchaser and Seller shall furnish to the
other such necessary information and reasonable assistance as the other may
request in connection with its preparation of any submission that is necessary
under the HSR Act. Seller and Purchaser shall keep each other apprised of the
status of any communications with, and any inquiries or requests for additional
information from, the FTC and the DOJ and shall comply promptly with any such
inquiry or request. Each of Seller and Purchaser shall use its best efforts to
obtain any clearance required under the HSR Act for the consummation of the
transactions contemplated by this Agreement.

            (b) Each of Seller and Purchaser shall use commercially reasonable
efforts to procure all applicable regulatory approvals necessary to consummate
the transactions contemplated hereby, including the transfer from Seller to
Purchaser, within 90 days of the Closing Date, of all Seller's rights, title and
interest to regulatory approvals relating to the Products or the Businesses.

            Section 4.8 Publicity. Except as otherwise required by law or
applicable stock exchange requirements, prior to the Closing neither Purchaser
nor Seller shall, and each of them shall cause their respective Affiliates,
representatives and agents not to, issue or cause the publication of any press
release or public announcement with respect to the transactions contemplated by
this Agreement without the express prior written approval of the other party,
which approval shall not unreasonably be withheld. The content of the initial
press release announcing the execution of this Agreement shall be mutually
agreed by Purchaser and Seller.

            Section 4.9 Supplemental Disclosure. Seller shall have the right
from time to time prior to the second business day preceding the Closing to
supplement or amend the Schedules with respect to any matter hereafter arising
or discovered which if existing or known at the date of this Agreement would
have been required to be set forth or described in any such Schedule. Any such
supplemental or amended disclosure shall not be deemed to have cured any breach
of any representation or warranty made in this Agreement for purposes of
determining whether or not the conditions set forth in Article V have been
satisfied, but will be deemed to have cured any such breach of representation or
warranty made in this Agreement and to have been disclosed as of the date of
this Agreement for purposes of Article VII hereof.

            Section 4.10 Further Assurances. Each party 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 each Related Instrument. With respect to all documents,
information and other materials included in the Acquired Assets, in addition to
paper and other tangible copies, Seller shall, upon Purchaser's request, also
provide to Purchaser electronic copies of such documents, information and other
materials, provided that Seller or its Affiliates or their respective agents
have electronic copies thereof. The foregoing requirement shall only apply to
such documents, information and other material exclusively related to the
Acquired Assets, and Seller shall have no obligation to reformat or otherwise
alter or modify any such materials in order to provide them to Purchaser.

of all product literature relating to the Products (i) to delete all references

customer service address or phone number; provided, however, that for a period
of six (6) months from the Closing Date Purchaser may continue to distribute
product literature that uses any Names, addresses or phone numbers to the extent
that such literature exists on the Closing Date, and Seller hereby grants to
Purchaser rights under any copyrights and other intellectual property owned by
Seller (and covenants to cause each of its Affiliates to grant Purchaser rights
under any copyrights and other intellectual property owned by such Affiliate) to
the extent necessary to allow Purchaser to so use such product literature. In no
event shall
<PAGE>   24
Purchaser use any Names after the Closing in any manner or for any purpose
different from the use of such Names by Seller during the 90-day period
preceding the Closing, except as provided in the Supply Agreements.

            (b) Seller hereby grants a non-exclusive right and license to
Purchaser under the Names to the extent necessary to allow Purchaser and its
Affiliates and their designees to market, distribute and sell the Products

            Section 4.12 Geographic Limitations. (a) After the Closing Date, and
so long as the [REDACTED], is in effect, Purchaser shall not, and shall not
permit its Affiliates to, market or sell, and shall use commercially reasonable
efforts to prevent any other Person from marketing or selling, any products
bearing the Estrace(R) name in [REDACTED]. In furtherance of the foregoing,
Purchaser shall (i) include the following provision in any agreement or on the
face of any purchase order form, invoice or similar instrument related to the
sale of Estrace Cream (in the case of purchase order forms, invoices or similar
instruments, only after exhaustion of Purchaser's existing stock of such
instruments): "Buyer shall use/sell/distribute the goods only within the country
where Seller has delivered them and shall not directly or indirectly, export
them to any other country" and (ii) if it becomes aware of any [REDACTED] by a
customer, use commercially reasonable efforts to prevent further resales by such
customer, including stopping sales to such customer.

            (b) Purchaser acknowledges and agrees:

            (i) that the Acquired Assets do not include or confer any rights to
      manufacture, distribute, market or sell any products under the "Estrace"
      name in Canada;

      [REDACTED] under such agreement, including registering, applying to
      register or otherwise using the Estrace(R) trademark (or a mark
      confusingly similar thereto) in [REDACTED] (unless otherwise agreed to in
      writing by [REDACTED]).

            (c) Seller agrees that it will not amend, supplement or otherwise
modify the provisions of the [REDACTED] related to the Estrace(R) trademark.
<PAGE>   25
            Section 4.13 Bulk Transfer Laws. Purchaser hereby waives compliance
by Seller and its Affiliates with the provisions of any so-called "bulk transfer
law" of any jurisdiction in connection with the sale of the Acquired Assets to
Purchaser.

            Section 4.14 Right of First Negotiation. If, during the period from
the Closing Date until the fifth anniversary thereof, Seller (or any of its
Affiliates) determines that it is interested in entering into an arrangement
with an unaffiliated person (hereinafter a "Third Party") to sell or out-license
the right to sell (any such rights being hereafter referred to as a "Right") any
of the Excluded Estrace Products (subject to the Roberts Agreement), Seller (or
any of its Affiliates, as applicable) shall give Purchaser a right of first
negotiation to acquire such Right as follows:

            (a) Seller shall give written notice to Purchaser of its (or any of
its Affiliates) interest in selling or out-licensing the Right. Purchaser shall
have fifteen (15) days after receipt of such notice to decide whether or not it
wishes to pursue negotiations for such an arrangement with respect to such Right
and to submit a proposal to Seller. In the event that Purchaser declines to
pursue negotiations or does not reply to Seller's notice within the fifteen (15)
day period, Seller (or any of its Affiliates, as applicable) shall be free to
negotiate and enter into an arrangement with respect to such Right with a Third
Party.

            (b) In the event that Purchaser expresses interest in negotiations
and submits a preliminary proposal, then for an additional thirty (30) day
period, Seller shall conduct negotiations on an exclusive basis with Purchaser
diligently and in good faith to reach an agreement with Purchaser. At the end of
such thirty (30) day period, if the parties have not reached an agreement at
such time, Purchaser shall give Seller a written notice setting forth the final
offer by Purchaser for such an arrangement (the "Final Offer"). If Seller (or
any of its Affiliates, as applicable) rejects the Final Offer, it shall
thereafter be free to negotiate and enter into an arrangement with respect to
such Right with a Third Party as provided in Section 4.14(c) below.

            (c) In the event Seller and Purchaser fail to negotiate a written
agreement pursuant to Sections 4.14(b) above within the period provided therein,
Seller (or any of its Affiliates, as applicable) shall be free to enter into an
arrangement for the selling or out-licensing of the Right with a Third Party;
provided, however, that for a period of twelve months from the expiration of the
thirty (30) day exclusive negotiation period set forth in Section 4.14(b) Seller
shall not, and shall cause its Affiliates not to, enter into an arrangement with
a Third Party with respect to such Right on terms less favorable to Seller and
its Affiliates than the Final Offer without first reoffering to Purchaser the
opportunity to enter into an arrangement on the terms set forth in the Final
Offer. In the event of such a reoffer, Purchaser shall have fifteen (15) days to
advise Seller of its interest in entering into an arrangement on such terms. In
the event that Purchaser expresses interest in such an arrangement on such
terms, Purchaser and Seller (or any of Seller's Affiliates, as applicable) shall
conduct exclusive negotiations and conclude an agreement incorporating such
terms within thirty (30) days thereafter. For purposes of
<PAGE>   26
this Section 4.14(c), Purchaser acknowledges and agrees that Seller (or any of
its Affiliates, as applicable) shall have the right, in its sole discretion, to
determine whether an offer from a Third Party that consists in whole or in part
of non-cash compensation is more or less favorable to Seller and its Affiliates
than the Final Offer.

            Section 4.15 Copromotion Agreement. (a) Purchaser acknowledges and
agrees that by execution of this Agreement, Seller and its Affiliates have
satisfied their obligation under Section 15 of the Copromotion Agreement
entitled "Right of First Negotiation".

            (b)  Each of Purchaser and Seller agrees that:

            (i) the Copromotion Agreement shall remain in full force and effect
      up to the Closing Date;

            (ii) until such date, it will perform under the Copromotion
      Agreement in the ordinary course of business and consistent with past
      practice; and

            (iii) upon the Closing, the Copromotion Agreement shall terminate;
      provided that each party thereto shall remain liable for any obligations
      or liabilities thereunder (including payment obligations) which survive
      such termination, in accordance with Section 12 thereof.

            (c) Each of Purchaser and Seller agrees that upon the Closing the
License Agreement among Purchaser, Warner Chilcott Laboratories Ireland Limited
("WC Ireland") and Seller dated as of February 1, 1999 (the "Ovcon License
Agreement"), shall terminate; provided that each party thereto shall remain
liable for any obligations or liabilities thereunder (including payment
obligations) which survive such termination in accordance with Section 8
thereof.

            (d) on the Closing Date (i) Purchaser shall enter into, and Seller
shall cause Apothecon, Inc. to enter into, a termination agreement with respect
to the Copromotion Agreement that is consistent with Section 4.15 (b)(iii) and
(ii) Purchaser and Seller shall enter into, and Purchaser shall cause WC Ireland
to enter into, a termination agreement with respect to the Ovcon License
Agreement that is consistent with Section 4.15(c).

            Section 4.16 Customer Notifications. Promptly after the Closing
Date, Seller and Purchaser shall jointly notify all customers of the Businesses
(i) of the transfer of the Acquired Assets to Purchaser, (ii) that all purchase
orders for Products received by Seller or any of its Affiliates prior to the
Closing Date but not filled as of such date will be transferred to Purchaser;
provided that, to the extent that any purchase order cannot be so transferred,
Seller and Purchaser shall cooperate with each other to ensure that such
purchase order is filled and that Purchaser receives the same economic benefit
and assumes the same liability associated with filling such purchase order as if
such purchase order had been so transferred, and (iii) that all subsequent
purchase orders for Products
<PAGE>   27
should be sent to Purchaser at Warner Chilcott, Inc., 100 Enterprise Drive,
Suite 280, Rockaway, NJ 07866, attention: William Poll, V.P. Finance & Trade
Relations. Seller and Purchaser shall share the costs of such notification.

            Section 4.17 Post-Closing Cooperation. (a) Purchaser and Seller
shall cooperate with each other, and shall cause their officers, employees,
agents, auditors, Affiliates and representatives to cooperate with each other,
for a period of 180 days after the Closing to ensure the orderly transition of
the Businesses from Seller to Purchaser and to minimize any disruption to the
Businesses and the other respective businesses of Seller and Purchaser that
might result from the transactions contemplated hereby. After the Closing, upon
reasonable written notice, Purchaser and Seller shall furnish or cause to be
furnished to each other and their employees, counsel, auditors and
representatives access, during normal businesses hours, to such information and
assistance relating to the Businesses (to the extent within the control of such
party) as is reasonably requested for financial reporting and accounting
matters.

            (b) After the Closing, upon reasonable written notice, Purchaser and
Seller shall furnish or cause to be furnished to each other, as promptly as
practicable, such information and assistance (to the extent within the control
of such party) relating to the Acquired Assets (including access to books and
records) as is reasonably requested for the filing of all Tax returns, and
making of any election related to Taxes, the preparation for any audit by any
Taxing authority, and the prosecution or defense of any claim, suit or
proceeding related to any Tax return. Seller and Purchaser shall cooperate with
each other in the conduct of any audit or other proceeding relating to Taxes
involving the Businesses. Purchaser shall retain the books and records of Seller
and its Affiliates included in the Acquired Assets for a period of seven years
after the Closing. After the end of such seven-year period, before disposing of
such books or records, Purchaser shall give notice to such effect to Seller and
shall give Seller, at Seller's cost and expense, an opportunity to remove and
retain all or any part of such books or records as Seller may select.

            (c) Each party shall reimburse the other for reasonable
out-of-pocket costs and expenses incurred in assisting the other pursuant to
this Section 4.17. Neither party shall be required by this Section 4.17 to take
any action that would unreasonably interfere with the conduct of its business or
unreasonably disrupt its normal operations (or, in the case of Purchaser, the
Businesses).

            Section 4.18 Covenant Not to Compete. (a) After the Closing, Seller
shall not, and shall cause its subsidiaries not to, (i) for a period of ten (10)
years following the Closing Date, engage in the manufacture, marketing,
distribution or sale of any generic equivalent of any Product or (ii) for a
period of three (3) years following the Closing Date, engage in the manufacture,
marketing, distribution or sale of any product for hormone replacement therapy,
in cream form and vaginally applied, that has 17(beta)-Estradiol as its primary
active ingredient (each of (i) and (ii) being a "Competitive Business").
<PAGE>   28
            (b) The foregoing shall not be construed to prevent Seller or any of
its subsidiaries from doing any of the following: (i) manufacturing Estrace
Cream under the Estrace Supply Agreement, (ii) manufacturing, marketing,
distributing or selling a product in tablet form under the name Estrace(R),
(iii) acquiring any Person that derives less than 5% of its revenues from a
Competitive Business (or any Person that derives an amount equal to or in excess
of 5% of its revenues from a Competitive Business so long as Seller causes such
Person to divest such Competitive Business within two (2) years from the date of
acquisition), and thereafter owning, managing, operating or controlling such
Person, (iv) owning up to 10% of the voting equity securities or any non-voting
equity or debt securities of any Person primarily engaged in a Competitive
Business whose securities are publicly traded on a national securities exchange
or in the over-the-counter market (or an amount in excess of 10% so long as
Seller divests such excess within two (2) years), or (v) owning any equity or
debt securities through any employee benefit or pension plan.

notwithstanding anything to the contrary contained herein or in any certificate
delivered pursuant hereto.

            Section 5.5 Frustration of Closing Conditions. Neither Purchaser nor
Seller may rely on the failure of any condition set forth in this Article V to
be satisfied if such failure was caused by such party's failure to act in good
faith or to use its best efforts to cause the Closing to occur, to the extent
required by Section 4.4. Purchaser may only rely on the failure of the condition
set forth in Section 5.2(e) if it has used commercially reasonable efforts in

                                   ARTICLE VI

time prior to the Closing by:

            (a) Mutual consent of Seller and Purchaser;

            (b) Either Seller or Purchaser if the Closing shall not have
occurred on or before June 30, 2000 (unless the failure to consummate the

Agreement);

            (c) Either Seller or Purchaser if a condition to its obligation to
perform becomes incapable of fulfillment and such condition shall not have been
waived by the other party; provided, that Seller or Purchaser, as the case may
be, may not seek termination pursuant to this Section 6.1(c) if such condition
is incapable of fulfillment due to the failure of Seller or Purchaser, as the
case may be, to perform the agreements set forth herein required to be performed
by such party, at or before the Closing; or

            (d) Either Seller or Purchaser if any court of competent
jurisdiction or other competent Governmental Entity shall have issued a statute,
rule, regulation, order, decree or injunction or taken any other action
permanently restraining, enjoining or otherwise prohibiting the transactions
contemplated by this Agreement and such statute, rule, regulation, order, decree
or injunction or other action shall have become final and nonappealable.

obligations under this Agreement which were within Seller's control), (vi)
Section 4.8 relating to publicity and (vii) Section 8.7 relating to governing
law. Nothing in this Section 6.2 shall be deemed to release any party from any
liability for any breach by such party of the terms and provisions of this
Agreement or to impair the right of any party to compel specific performance by
any other party of its obligations under this Agreement.

            Section 6.3 Amendments and Waivers. This Agreement may not be
amended except by an instrument in writing signed on behalf of each of the
parties hereto. By an instrument in writing Purchaser, on the one hand, or
Seller, on the other hand, may waive compliance by the other party with any term
or provision of this Agreement that such other party was or is obligated to
comply with or perform.

claim, damage or expense (including reasonable legal fees and expenses)
("Losses"), as incurred (payable promptly upon written request), to the extent
arising from:

            (i) any breach of any representation or warranty of Seller that
      survives the Closing and is contained in this Agreement (including the
      Schedules), the Seller's Officer's Certificate or in any Related
      Instrument (other than the Supply Agreements);

            (ii) subject to the provisions of Section 7.7(b), any breach of any
      covenant of Seller contained in this Agreement or in any Related
      Instrument (other than the Supply Agreements);

            (iii) any Excluded Liability; and

            (iv) any fees, expenses or other payments incurred or owed by Seller
      to any brokers, financial advisors or comparable other Persons retained or
      employed by it in connection with the transactions contemplated by this
      Agreement or by any Related Instrument.

            (b)  Seller shall not be required to indemnify any Person, and shall
not have any liability:

            (i) under clause (i) of Section 7.2 (a) unless the aggregate of all
      Losses for which Seller would, but for this clause (i), be liable exceeds
      on a cumulative basis an amount equal to $2,000,000, and then only to the
      extent of any such excess;

            (ii) under clause (i) of Section 7.2(a) for any individual items (or
      series of related individual items) where the Loss relating thereto is
      less than $50,000, in which case such items shall not be aggregated for
      purposes of clause (i) of this Section 7.2(b);

            (iii) under clause (i) of Section 7.2(a) in excess of an amount
      equal to $25,000,000; and

            (iv) under clause (i) of Section 7.2(a) to the extent the liability
      or obligation is directly caused by any action taken or omitted to be
      taken by Purchaser or any of its Affiliates;

provided, however, that the limitations in the preceding clauses (i)-(iv) of
this Section 7.2(b) shall not be applicable to indemnification under clause (i)
of Section 7.2(a) with respect to the representations and warranties set forth
in Sections 2.1 and 2.2.
<PAGE>   33
            Section 7.3 Indemnification by Purchaser. Purchaser shall indemnify
Seller, its Affiliates and each of their respective officers, directors,
employees, stockholders, agents and representatives against, and agrees to hold
them harmless from, any Loss, as incurred (payable promptly upon written
request), to the extent arising from or in connection with or otherwise with
respect to:

            (a) any breach of any representation or warranty of Purchaser that
survives the Closing and is contained in this Agreement, the Purchaser's
Officer's Certificate or in any Related Instrument (other than the Supply
Agreements); provided that Purchaser shall not be required to indemnify any
Person, and shall not have any liability under this Section 7.3(a) to the extent
the liability or obligation is directly caused by any action taken or omitted to
be taken by Purchaser or any of its Affiliates; provided further, however, that
the limitation in the preceding proviso shall not be applicable to
indemnification under this clause (a) of Section 7.3 with respect to the
representations and warranties set forth in Sections 3.1 and 3.2;

            (b) subject to the provisions of Section 7.7(b), any breach of any
covenant of Purchaser contained in this Agreement or in any Related Instrument
(other than the Supply Agreements);

            (c) any Assumed Liability; and

Purchaser to any brokers, financial advisors or other comparable Persons
retained or employed by it in connection with the transactions contemplated by
this Agreement or by any Related Instrument.

            Section 7.4 Calculation of Losses. The amount of any Loss for which
indemnification is provided under clause (i) of Section 7.2(a) or clause (a) of
Section 7.3 shall be net of any amounts actually recovered by the indemnified
party under insurance policies with respect to such Loss and shall be (a)
increased to take account of any net Tax cost incurred by the indemnified party
arising from the receipt of indemnity payments hereunder (grossed up for such
increase) and (b) reduced to take account of any net Tax benefit immediately
realized by the indemnified party in cash arising from the incurrence or payment
of any such Loss. In computing the amount of any such Tax cost or Tax benefit,
the indemnified party shall be deemed to recognize all other items of income,
gain, loss deduction or credit before recognizing any item arising from the
receipt of any indemnity payment under clause (i) of Section 7.2(a) or clause
(a) of Section 7.3 or the incurrence or payment of any indemnified Loss. Any
indemnity payment under clause (i) of Section 7.2(a) or clause (a) of Section
7.3 shall be treated as an adjustment to the Purchase Price for Tax purposes,
unless a final determination (which shall include the execution of a Form 870-AD
or successor form) with respect to the indemnified party or any of its
Affiliates causes any such payment not to be treated as an adjustment to such
price for federal income Tax purposes.

            Section 7.5 Termination of Indemnification. The obligations to
indemnify and hold harmless any party, (a) pursuant to Section 7.2(a)(i) or
7.3(a), shall terminate on the eighteen-month anniversary of the Closing Date
(except to the extent that pursuant to Section 7.1 any representation or
warranty survives past such anniversary) and (b) pursuant to the other clauses
of Sections 7.2 and 7.3, shall not terminate; provided, however, that such
obligations to indemnify and hold harmless shall not terminate with respect to
any item as to which the Person to be indemnified shall have, before the
expiration of the applicable period, previously made a claim by delivering a
notice of such claim (stating in reasonable detail the basis of such claim)
pursuant to Section 7.6 to the party to be providing the indemnification.

            Section 7.6 Procedures. (a) In order for a party (the "indemnified
party") to be entitled to any indemnification provided for under this Agreement
in respect of, arising out of or involving a claim made by any Person against
the indemnified party (a "Third Party Claim"), such indemnified party must
notify the indemnifying party (the "indemnifying party") in writing (and in
reasonable detail) of the Third Party Claim within 15 business days after
receipt by such indemnified party of notice of the Third Party Claim; provided,
however, that failure to give such notification shall not affect the
indemnification provided hereunder except to the extent the indemnifying party
shall have been actually prejudiced as a result of such failure (except that the
indemnifying party shall not be liable for any expenses incurred during the
period in which the indemnified party failed to give such notice). Thereafter,
the indemnified party shall deliver to the indemnifying party, within five
business days' time after the indemnified party's receipt thereof, copies of all
notices and documents (including court papers) received by the indemnified party
relating to the Third Party Claim.

            (b) If a Third Party Claim is made against an indemnified party, the
indemnifying party shall be entitled to participate in the defense thereof and,
if it so chooses, to assume the defense thereof with counsel selected by the
indemnifying party. Should the indemnifying party so elect to assume the defense
of a Third Party Claim, the indemnifying party shall not be liable to the
indemnified party for any legal expenses subsequently incurred by the
indemnified party in connection with the defense thereof. If the indemnifying
party assumes such defense, the indemnified party shall have the right to
participate in the defense thereof and to employ counsel, at its own expense,
separate from the counsel employed by the indemnifying party, it being
understood that the indemnifying party shall control such defense. The
indemnifying party shall be liable for the fees and expenses of counsel employed
by the indemnified party for any period during which the indemnifying party has
not assumed the defense thereof (other than during any period in which the
indemnified party shall have failed to give notice of the Third Party Claim as
provided above). If the indemnifying party chooses to defend or prosecute a
Third Party Claim, all the indemnified parties shall cooperate in the defense or
prosecution thereof. Such cooperation shall include the retention and (upon the
indemnifying party's request) the provision to the indemnifying party of records
and information that are reasonably relevant to such Third Party Claim, and
making employees available on a mutually convenient basis to provide additional
information and explanation of any material provided hereunder. Whether or not
the indemnifying party
<PAGE>   35
assumes the defense of a Third Party Claim, the indemnified party shall not
admit any liability with respect to, or settle, compromise or discharge, such
Third Party Claim without the indemnifying party's prior written consent (which
consent shall not be unreasonably withheld). If the indemnifying party assumes
the defense of a Third Party Claim, the indemnified party shall agree to any
settlement, compromise or discharge of a Third Party Claim that the indemnifying
party may recommend and that by its terms obligates the indemnifying party to
pay the full amount of the liability in connection with such Third Party Claim,
which releases the indemnified party completely in connection with such Third
Party Claim and that would not otherwise materially adversely affect the
indemnified party.

            (c) Other Claims. In the event any indemnified party should have a
claim against any indemnifying party under Section 7.2 or 7.3 that does not
involve a Third Party Claim being asserted against or sought to be collected
from such indemnified party, the indemnified party shall deliver notice of such
claim with reasonable promptness to the indemnifying party. The failure by any
indemnified party so to notify the indemnifying party shall not relieve the
indemnifying party from any liability that it may have to such indemnified party
under Section 7.2 or 7.3, except to the extent that the indemnifying party
demonstrates that it has been prejudiced by such failure. If the indemnifying
party disputes its liability with respect to such claim, the indemnifying party
and the indemnified party shall proceed in good faith to negotiate a resolution
of such dispute and, if not resolved through negotiations, such dispute shall be
resolved by litigation in an appropriate court of competent jurisdiction.

            Section 7.7 Sole Remedy; No Additional Representations. (a) Except
as otherwise specifically provided in Section 1.6(c) or in any Related
Instrument, each of Purchaser and Seller acknowledges and agrees that, to the
extent the Closing occurs, its sole and exclusive remedy after the Closing with
respect to any and all claims and causes of action relating to this Agreement
(including the Schedules), the Seller's Officer's Certificate, the Purchaser's
Officer's Certificate and the Related Instruments (other than the Supply
Agreements), the Acquisition and the other transactions contemplated hereby and
thereby, the Businesses, the Acquired Assets and the Assumed Liabilities (other
than claims of, or causes of action arising from, fraud or relating to breaches
of covenants requiring performance after the Closing Date) shall be pursuant to
the indemnification provisions set forth in this Article VII. In furtherance of
the foregoing, each of Purchaser and Seller hereby waives, from and after the
Closing, to the fullest extent permitted under applicable law, any and all
rights, claims and causes of action relating to this Agreement (including the
Schedules), the Seller's Officer's Certificate, the Purchaser's Officer's
Certificate and the Related Instruments (other than the Supply Agreements), the
Acquisition and the other transactions contemplated hereby and thereby, the
Businesses, the Acquired Assets and the Assumed Liabilities (other than claims
of, or causes of action arising from, fraud or relating to breaches of covenants
requiring performance after the Closing Date) it may have against the other
party hereto arising under or based upon any applicable law or arising under or
based upon common law or otherwise (except pursuant to the indemnification
provisions set forth in Section 7.2 or Section 7.3, as applicable).
<PAGE>   36
            (b) Each of Purchaser and Seller acknowledges and agrees that, to
the extent the Closing occurs, it shall not have any remedy after the Closing
with respect to any and all claims and causes of action relating to any breach
of any covenant requiring performance prior to the Closing under this Agreement
(including the Schedules) (other than claims of, or causes of action arising
from, fraud); provided that this Section 7.7(b) shall not apply to any breach of
a covenant that requires performance prior to and after the Closing to the
extent any breach of such covenant occurs after the Closing.

            (c) Purchaser acknowledges that it and its representatives have been
permitted full and complete access to the books and records, facilities,
equipment, tax returns, contracts, insurance policies (or summaries thereof) and
other properties and assets of the Businesses that it and its representatives
have desired or requested to see or review, and that it and its representatives
have had a opportunity to meet with the officers and employees of Seller and its
Affiliates to discuss the Businesses. For the avoidance of doubt, Purchaser's
access to such information and its opportunity to meet with such personnel shall
not limit Purchaser's right to make a claim for indemnification under Section
7.2(a).

            (d) Purchaser acknowledges that none of Seller, its Affiliates or
any other Person has made any representation or warranty, expressed or implied,
as to the accuracy or completeness of any information regarding the Businesses
furnished or made available to Purchaser and its representatives, except as
expressly set forth in this Agreement (including the Schedules), the Related
Instruments or the Seller's Officer's Certificate, and none of Seller, its
Affiliates or any other Person shall have or be subject to any liability to
Purchaser or any other Person resulting from the distribution to Purchaser, or
Purchaser's use of, any such information, documents or material made available
to Purchaser in any "data rooms", management presentations or in any other form
in expectation of the transactions contemplated hereby except to the extent such
information, documents or materials is included in the representations or
warranties of the Seller set forth in this Agreement (including the Schedules),
the Related Instruments or the Seller's Officers' Certificates.

            (e) Purchaser also acknowledges that, should the Closing occur,
except as expressly set forth in the representations and warranties set forth in
Article II of this Agreement (including the Schedules), Related Instrument or in
the Seller's Officer's Certificate, there are no representations or warranties
by Seller of any kind, express or implied, with respect to the Businesses, and
that Purchaser is purchasing the Acquired Assets "as is", "where is" and "with
all faults". Without limiting the generality of the foregoing, except as
expressly set forth in the representations and warranties set forth in Article
II of this Agreement (including the Schedules), the Related Instruments or in
the Seller's Officer's Certificate, THERE ARE NO EXPRESS OR IMPLIED WARRANTIES
OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

      Section 7.8 Limitations on Liability. (a) Notwithstanding any provision
herein, neither Seller nor Purchaser shall in any event be liable to the other
party or its Affiliates, officers, directors, employees, stockholders, agents or
representatives on account of any
<PAGE>   37
indemnity obligation set forth in Section 7.2(a)(i) or 7.3(a) for any indirect,
consequential or punitive damages (including, but not limited to, lost profits,
loss of use, damage to goodwill or loss of business).

            (b) Seller and Purchaser shall cooperate with each other in
resolving any claim or liability with respect to which one party is obligated to
indemnify the other under this Agreement, including without limitation, by
making commercially reasonable efforts to mitigate or resolve any such claim or
liability.

            Section 8.3 Descriptive Headings. The descriptive headings herein
are inserted for convenience only and are not intended to be part of or to
affect the meaning or interpretation of this Agreement.

            Section 8.4 Counterparts. This Agreement may be executed in one or
more counterparts, all of which shall be considered one and the same agreement,
and shall become effective when one or more such counterparts have been signed
by each of the parties and delivered to the other party.

            Section 8.5 Entire Agreement. This Agreement (including the
Schedules) the Purchaser's Officer's Certificate, the Seller's Officer's
Certificate, the Related Instruments and the Confidentiality Agreement, along
with the Schedules and Exhibits hereto and thereto, contain the entire agreement
and understanding between the parties hereto with respect to the subject matter
hereof and supersede all prior agreements and understandings relating to such
subject matter. Neither party shall be liable or bound to any other party in any
manner by any representations, warranties or covenants relating to such subject
matter except as specifically set forth herein (including the Schedules) the
Purchaser's Officer's Certificate, the Seller's Officer's Certificate or in the
Related Instruments or the Confidentiality Agreement.

            Section 8.6 Fees and Expenses. Regardless of whether or not the
transactions contemplated by this Agreement are consummated, each party shall
bear its own fees and expenses incurred in connection with the transactions
contemplated by this Agreement and the Related Instruments.

            Section 8.7 Governing Law. This Agreement shall be governed by and
construed in accordance with the internal laws of the State of New York
applicable to agreements made and to be performed entirely within such State,
without regard to the conflicts of law principles of such State.

            Section 8.8 Specific Performance. The parties hereto agree that if
any of the provisions of this Agreement were not performed in accordance with
their specific terms or were otherwise breached, irreparable damage would occur,
no adequate remedy at law would exist and damages would be difficult to
determine, and that the parties shall be entitled to specific performance of the
terms hereof, in addition to any other remedy at law or equity.

            Section 8.9 Assignment. This Agreement may not be assigned by any
party hereto without the prior written consent of the other party; provided that
Purchaser may assign its rights (but not its obligations) under this Agreement
in connection with its proposed financing of the Acquisition prior to the
Closing: (i) to Warner Chilcott PLC, if Purchaser fully and unconditionally
guarantees the obligations of such entity, or (ii) to its lenders (other than
lenders which are or may become public noteholders) as security for its
obligations to such lenders. Any attempted assignment in violation of this
Section 8.9 shall be void.
<PAGE>   45
            Section 8.10 Successors and Assigns. This Agreement shall be binding
upon and inure solely to the benefit of the parties hereto, their successors and
permitted assigns, and nothing in this Agreement, express or implied, is
intended to or shall confer upon any other person or persons any right, benefits
or remedies of any nature whatsoever under or by reason of this Agreement.

            Section 8.11 Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstances, is
held invalid, illegal or unenforceable in any respect for any reason, the
parties shall negotiate in good faith with a view to the substitution therefor
of a suitable and equitable solution in order to carry out, so far as may be
valid and enforceable, the intent and purpose of such invalid provision;
provided, however, that the validity, legality and enforceability of any such
provision in every other respect and of the remaining provisions contained
herein shall not be in any way impaired thereby, it being intended that all of
the rights and privileges of the parties hereto shall be enforceable to the
fullest extent permitted by law.

            Section 8.12 Consent to Jurisdiction. Each of Purchaser and Seller
irrevocably submits to the exclusive jurisdiction of (a) the Supreme Court of
the State of New York, New York County, and (b) the United States District Court
for the Southern District of New York, for the purposes of any suit, action or
other proceeding arising out of this Agreement, any Related Instrument or any
transaction contemplated hereby or thereby. Each of Purchaser and Seller agrees
to commence any such action, suit or proceeding either in the United States
District Court for the Southern District of New York or if such suit, action or
other proceeding may not be brought in such court for jurisdictional reasons, in
the Supreme Court of the State of New York, New York County. Each of Purchaser
and Seller further agrees that service of any process, summons, notice or
document by U.S. registered mail to such party's respective address set forth
above shall be effective service of process for any action, suit or proceeding
in New York with respect to any matters to which it has submitted to
jurisdiction in this Section 8.12. Each of Purchaser and Seller irrevocably and
unconditionally waives any objection to the laying of venue of any action, suit
or proceeding arising out of this Agreement, any Related Instrument or the
transactions contemplated hereby and thereby in (i) the Supreme Court of the
State of New York, New York County or (ii) the United States District Court for
the Southern District of New York, and hereby and thereby further irrevocably
and unconditionally waives and agrees not to plead or claim in any such court
that any such action, suit or proceeding brought in any such court has been
brought in an inconvenient forum.

            Section 8.13 Waiver of Jury Trial. Each party hereto hereby waives
to the fullest extent permitted by applicable law, any right it may have to a
trial by jury in respect to any litigation directly or indirectly arising out
of, under or in connection with this Agreement or any Related Instrument. Each
party hereto (a) certifies that no representative, agent or attorney of any
other party has represented, expressly or otherwise, that such other party would
not, in the event of litigation, seek to enforce that
<PAGE>   46
foregoing waiver and (b) acknowledges that it and the other parties hereto have
been induced to enter into this Agreement and the Related Instruments, as
applicable, by, among other things, the mutual waivers and certifications in
this Section 8.13.

            Section 8.14 Attorney Fees. A party in breach of this Agreement
shall, on demand, indemnify and hold harmless the other party for and against
all reasonable out-of-pocket expenses, including legal fees, incurred by such
other party by reason of the enforcement and protection of its rights under this
Agreement. The payment of such expenses is in addition to any other relief to
which such other party may be entitled.


            IN WITNESS WHEREOF, the parties hereto have executed this Agreement
as of the date first written above.
