              (f) Payment; Currency. All payments by Purchaser to Seller under

reasonable efforts to notify Purchaser of any payments owed to Seller that have
not been paid by the end of the Grace Period; provided, however, that Purchaser
acknowledges that Purchaser shall have no remedy in the event Seller fails to
provide such notice; provided further, that in the event Seller does not receive
a payment before the expiration of the Grace Period applicable to such payment,
and Purchaser is able to demonstrate that it made such payment in good faith
before the expiration of the Grace Period and that the failure of such payment
was through no fault of Purchaser, then Seller shall extend the Grace Period
until such time as it provides Purchaser with notice that such payment was not
received. Purchaser shall be responsible for and pay any and all costs,
including reasonable attorney's fees incurred by Seller in connection with
collecting past due amounts from Purchaser after the Grace Period.

              (h) Books and Records; Audits. Purchaser shall maintain at its
office, accurate and complete books and records of its sales relating to the
Products consistent with customary business and accounting practices and in such
form and in such detail as to enable the amount of payments payable hereunder to
be determined. Commencing January 1, 2000, no more than once per year, Purchaser
shall permit Seller or any representative of a nationally recognized accounting

                     As an inducement to Purchaser to enter into this Agreement
and consummate the transactions contemplated herein,
Seller represents and warrants to Purchaser that:


       4.1 Organization. The Seller is a corporation duly organized, validly
existing and in good standing under the laws of the State of its incorporation.
Seller is duly qualified or licensed as a foreign corporation in each
jurisdiction in which the nature of the Business makes such qualification or
licensing necessary, except those jurisdictions where the failure to so qualify
would not have a Material Adverse Effect.

       4.2  Valid and Binding Agreements.  The board of directors of Seller has
approved the consummation of the transactions contemplated hereby and by the
Closing Documents and no further corporate proceedings on the part of Seller are
necessary to consummate the transactions contemplated herein or therein. This
Agreement has been, and on the Closing Date each of the Closing Documents shall
be, duly and validly executed and delivered by Seller or its applicable
Affiliate, and this Agreement is, and on the Closing Date each of the Closing
Documents shall be, legal, valid and binding obligations of the Seller or its
applicable Affiliate, enforceable against Seller or its applicable Affiliate, in
accordance with their respective terms, subject to applicable bankruptcy,
insolvency and similar laws affecting creditors' rights generally and to general
principles of equity.

       4.3  No Violation, Etc.  Neither the execution and delivery of this
Agreement or the Closing Documents nor the consummation of the transactions
contemplated by this Agreement or the Closing Documents nor compliance by Seller
with any of the provisions hereof or thereof (a) violates or conflicts with any
provision of the certificate of incorporation or by-laws of Seller or (b)
violates, or conflicts with, or results in a breach of any provision of, or
constitutes a default (or gives rise to any right of termination, cancellation
or acceleration) under, any of the terms, conditions or provisions of any
agreement, lease, instrument, obligation, understanding or arrangement to which
Seller or Seller's properties or assets may be bound or affected by or (c)
violates any law, statute, rule or regulation to which Seller is subject.

declaration, filing or



                                       11
<PAGE>   17

registration with, any governmental authority or third party is necessary in
connection with the execution and delivery by Seller of this Agreement or the
Closing Documents or the consummation by it of the transactions contemplated
hereby or thereby, except such consents as would not have a Material Adverse
Effect.

       4.5 Compliance with Law, Etc. Seller has conducted its business and
operations, to the extent they relate to the manufacture, distribution and sale
of the Products, in compliance with, and obtained all permits, licenses and
other authorizations required under, all applicable laws, rules, regulations,
orders, ordinances, judgments and decrees of all governmental authorities
(federal, state and local) (collectively "Laws") including, without limitation,
all requirements imposed by the FDA, except for such non-compliance which would
not have a Material Adverse Effect. Seller has not within the past 24 months

Section 4.6 of the Disclosure Letter, Seller has good and marketable title to
the Purchased Assets, free and clear of all mortgages, security interests,
liens, encumbrances and charges of any kind or nature ("Liens"), except for such
Liens which would not have a Material Adverse Effect. The Purchased Assets
constitute all of the assets, properties, licenses and other arrangements that
are necessary to engage in the Business in a manner consistent with past
practice and at Seller's historic capacity; provided, however, that Purchaser
acknowledges that Seller has not and does not conduct any manufacturing

        to the Business and all agreements, oral or written pursuant to which
        Seller is obligated to pay royalties to third parties with respect to
        such intellectual property; and

               (vi)  all material license agreements, oral or written, pursuant
        to which Seller has granted to any person any outstanding right to any
        intellectual property relating to the Business and all agreements, oral
        or written, pursuant to which Seller is entitled to receive royalties
        from third parties with respect to such intellectual property, including
        licenses or other rights in unpatented formulations, manufacturing

Property referenced in clauses (i), (ii) and (iii) has been duly registered
with, filed in or issued by the United States Patent and Trademark Office to the
extent necessary, and to the extent any ownership of such Intellectual Property
has been registered, Seller is the registered owner thereof, in each case free

Effect, the registered trademarks referenced in clause (ii) of subsection (a)
above are (i) valid and (ii) enforceable in their respective countries of filing

knowledge no third party is infringing upon any of the Intellectual Property, no
claim exists that any of the Intellectual Property is not valid or enforceable
by Seller.

           (d) Except as would not have a Material Adverse Effect, Seller has
not taken or omitted any action which would have the effect of waiving any of
its rights under any of the Intellectual Property.

           (e) Except as would not have a Material Adverse Effect, no licenses,
sublicenses, or other agreements relating to the Intellectual Property exist
which would limit or restrict the rights of Purchaser to operate the Business or
which grant to a third party any rights in any Intellectual Property relating to
the Business.

           (f) Except as would not have a Material Adverse Effect, there are no
oppositions, cancellations or governmental, arbitration or other proceedings
currently pending or, to Seller's



                                       13

knowledge, threatened, that protest the rights of Seller to use and/or register
the trademarks and copyrights referenced in clauses (ii) and (iii) of subsection

not contravene, conflict with, violate or infringe upon any patent, trademark,
service mark, copyright or other intellectual property right of a third party
and no proprietary information or trade secret has been misappropriated by
Seller from any third party. In addition, the use, licensing or sale by Seller
of any of the Intellectual Property does not contravene, conflict with, violate
or infringe upon any patent, trademark, service mark, copyright or other
intellectual property right of a third party and does not require the agreement
or consent of any third party that has not been obtained.

                     (h) Other than the Warner Chilcott Trademarks, the
Intellectual Property constitutes all of the intellectual property used or
required by Seller to sell the Products.

       4.8  Litigation.  Except as set forth on Section 4.8 of the Disclosure

pending or to Seller's knowledge, threatened which affects in whole or in part

       6.3 Procedures for Control of Third Party Claims. The Purchaser
Indemnified Party or Seller Indemnified Party making a claim for indemnification
under this Section 6 shall be, for the purposes of this Agreement, referred to
as the "Indemnified Party" and the party against whom such claims are asserted
under this Section 6 shall be, for purposes of this Agreement, referred to as
the "Indemnifying Party". In order for an Indemnified Party to be entitled to
any indemnification provided for under this Agreement in respect of, arising out
of or involving a claim or demand, made by any person, firm, governmental
authority or corporation against the Indemnified Party (a "Third Party Claim")
such Indemnified Party must notify the Indemnifying Party in writing of the
Third Party Claim within ten (10) business days after receipt by such
Indemnified Party of written 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 and materially prejudiced as a result of such failure. If a Third Party
Claim is made against an Indemnified Party, the Indemnifying Party shall be
entitled to participate in the defense thereof and, upon notice to the
Indemnified Party, to assume the defense thereof; provided, that (i) the
Indemnifying Party's counsel is reasonably satisfactory to the Indemnified
Party, and (ii) the Indemnifying Party shall thereafter consult with the
Indemnified Party upon the Indemnified Party's reasonable request for such
consultation from time to time with respect to such suit, action or proceeding.
If the Indemnifying Party assumes such defense, the Indemnified Party shall have
the right (but not the duty) to participate in the defense thereof and to employ
counsel, at its own expense, separate from the counsel employed by the
Indemnifying Party. 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, but 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. Whether or not the Indemnifying Party chooses to defend or
prosecute any Third Party Claim, the parties hereto 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 which are reasonably relevant to such Third Party
Claim, and making employees or any other Indemnified Party available on a
mutually convenient basis to provide additional information and explanation of
any material provided hereunder. Whether or not the Indemnifying Party shall
have assumed the defense of a Third Party Claim, neither the Indemnifying Party
nor the Indemnified Party shall admit any liability with respect to, or settle,
compromise or discharge, such Third Party Claim without the other party's prior
written consent, which shall not be unreasonably withheld, conditioned or
delayed.

       6.4 Survival of Representations and Warranties. No claim or action for
indemnity under Sections 6.1(i) or 6.2(i) shall be asserted or maintained by an
Indemnified Party after the expiration of twenty-four (24) months following the
Closing Date, except for (i) a claim for indemnity made in writing by an
Indemnified Party to an Indemnifying Party prior to such expiration, which sets
forth in detail the basis for such claim or (ii) a claim by Seller pursuant to
Section 5.6, which may be asserted until the termination of all rights of Seller
to receive royalty payments pursuant to Section 2.4(d).

<PAGE>   25



       6.5 Limits on Indemnification. No claim for indemnification under Section
6.1(i) and 6.2(i) may be made, and no payment in respect thereof shall be
required unless the aggregate amount of Losses against which an Indemnified
Party is entitled to be indemnified exceeds tw0 hundred thousand dollars
($200,000.00), in which case the Indemnifying Party shall be liable for all
Losses, including all Losses up to and including two hundred thousand dollars
($200,000.00). The maximum aggregate amount of Losses that an Indemnified Party
shall be entitled to pursuant to Section 6 shall be ten million dollars
($10,000,000.00). The amount of any recovery to which an Indemnified Party may
be entitled pursuant to this Section 6 shall be net of (i.e., after deducting)
all national, federal, state, provincial and local income tax benefits and
insurance proceeds inuring to such Indemnified Party as a result of the set of
facts which entitle such Indemnified Party to recover from the Indemnifying
Party pursuant to this Section 6. Notwithstanding anything contained in this
Section 6.5, Seller shall be liable to Purchaser for all Losses, without regard
to the minimum or limitation contained in this Section 6.5, suffered by
Purchaser in connection with the lawsuit styled Natasha Frazier v. Lederle
Laboratories, American Cyanamid, Warner Chilcott, Inc., Warner Lambert Company,
R.M. McMillin, M.D. and Roane County Family Practice.

       6.6 Limitation of Consequential and Other Damages. In no event shall
Purchaser or Seller be liable for indirect, special, incidental, consequential
or punitive damages suffered by the other party or an Indemnified Party,
including, costs of procurement of substitute Product or services, business
interruption losses, loss of business relationships or lost profits; provided,
however, that nothing in this Section 6.6 shall be deemed to limit the
indemnification obligations of Purchaser and Seller in this Section 6 to the
extent a third party recovers any indirect, special, incidental, consequential
or punitive damages from an Indemnified Party.

       6.7 Assumption of Risk. (a)  Except as set forth in Section 6.7(b),
Purchaser assumes all risk of and liability for loss, damage or injury, proven
or unproven, to persons or property arising out of the manufacture, use,
possession, packaging, testing, labeling, distribution or sale of the Products
occurring on or after the Closing Date. After the Closing, Purchaser shall be
responsible for compliance with all regulatory matters in relation to the
Products, materials incorporated therein and the Purchased Assets (including the
labels, inserts, packaging and processes used in connection thereto) and
Purchaser shall be responsible for any and all communications with its customers
regarding the Products and all of the foregoing. Except as set forth in Section
6.7(b), Seller shall bear no responsibility for the content and/or form of any
warning, instruction or labeling provided in connection with Product sold by
Purchaser on or after the Closing Date or otherwise communicated to customers.
Purchaser shall not make any claim or raise any defense against Seller nor take
any position in any litigation inconsistent with the provisions of this Section
6.7.

                     (b) Notwithstanding the foregoing, in the event Purchaser
shall be liable to any third party for any Losses for any product liability
claim relating to any Product included as part of the Inventory transferred
pursuant to this Agreement, subject to Section 6.5, Seller shall indemnify
Purchaser for such Losses; provided that Seller shall not be required to
indemnify Purchaser for any Losses under this Section 6.7(b) to the extent and
only to the extent, (i) any such Loss is attributable to Purchaser's failure to
handle the Inventory in a manner consistent with industry practice or (ii) any



                                       20
<PAGE>   26

such Loss is otherwise attributable to Purchaser's or its Affiliates' or either
of their agents' gross negligence or wilful misconduct.

the New Product. In addition, Purchaser shall pay any user fees associated with

be solely liable and responsible for all Payment Claims whether received by

reasonably desirable in connection with the transactions contemplated by this
Agreement.

non-exclusive, non-transferable, royalty-free license until (i) Purchaser is in
a position to distribute Products without use of packaging and labeling
materials containing Warner Chilcott Trademarks, or (ii) twelve (12) months

Trademarks to the extent necessary to distribute and sell the Products using the
existing packaging and labeling materials forming part of the Inventory;
provided, that Purchaser shall use its reasonable efforts to make all necessary
arrangements as soon as possible to enable Purchaser to ship Products without

tax audits or (ii) prosecuting or defending any claim, litigation, proceeding or
investigation which arises out of or relates to the Products or the Purchased
Assets.

       7.12 Further Assurance. Each party hereto shall use all reasonable
efforts to implement the provisions of this Agreement, and for such purpose each
party, at the request of the other party, at or after the Closing, shall,
without further consideration, (except as provided in Section 7.2) execute and
deliver, or cause to be executed and delivered, to the other party such deeds,
assignments, bills of sale, consents and other instruments in addition to those

party, as such other party may reasonably deem necessary or desirable to
implement any provision of this Agreement.

the Purchased Assets not attributable to either party, shall be split evenly
between the parties.

       7.14 Noncompetition Agreement.Except as provided to the contrary below,
Seller agrees with the Purchaser, for the Purchaser's sole and exclusive
benefit, that for a period commencing on the Closing Date until the termination
of all rights of Seller to receive royalty payments pursuant to Section 2.4(d),
neither Seller nor any of its Affiliates shall, directly or indirectly, engage
in the Business or develop, manufacture, distribute, package, test, market or
sell (i) any Developing Product or (ii) any line extensions or improvements on
any Product or Developing Product; provided, however, that the foregoing
covenant shall not apply with respect to (i) any Person that acquires a majority
of the stock or assets of Seller or Warner Chilcott PLC, or any Person that
acquires a majority of the stock or assets of an Affiliate of Seller, that prior
to such acquisition already shall engage in the business described in the
foregoing covenant; or (ii) the ownership or acquisition of up to five percent
by Seller or any of its Affiliates of any Person which is engaged in the
business described in the foregoing covenant; or (iii) the acquisition by Seller
or any of its Affiliates of a majority of the stock or a majority of the assets
of a Person that engages in the business described in the foregoing covenant;
provided with respect to (iii), that the portion of the business of such Person
that so competes does not exceed ten percent of the total business of such
Person.

                     Seller and the Purchaser agree that a breach of this
Section 7.14 shall cause irreparable harm to the Purchaser
and its Affiliates, that Purchaser's remedies at law for any breach or threat of
breach of the provisions of this Section 7.14 shall be inadequate, and that the
Purchaser shall be entitled to an injunction or injunctions to prevent breaches
of this Section 7.14 and to enforce specifically the terms and provisions
hereof, in addition to any other remedy to which Purchaser may be entitled at
law or in equity.

                     Seller acknowledges that (i) the scope of the protective
restrictions provided for in this Section are reasonable when taking into

consideration being paid to Seller pursuant to this Agreement is sufficient
inducement for Seller to agree to the terms hereof, (iii) the provisions of this
Section are reasonable and necessary to protect the Business of the Purchaser
and (iv) the terms of this Section preclude Seller from competing with Purchaser
with respect to the Business, the Developing Products and any line extensions
and improvements on any Product or Developing Product.

the contrary in this Agreement, Seller shall not transfer or assign any interest
in any Permit, and Purchaser shall not assume any liability arising thereunder
or resulting therefrom, if an assignment or transfer or an attempt to make an

or affect adversely the rights of Purchaser or Seller thereunder, until such
consent has been obtained.

in writing or orally, by one party or its Affiliates, directors, officers,

of such Confidential Information, keep such Confidential Information and each
part thereof within its possession or under its control, use all its reasonable
best efforts to prevent the disclosure of any Confidential Information to any
other person, and use all its reasonable best efforts to ensure that such

party being required to disclose the other party's Confidential Information,
prior to such disclosure, shall notify the other party in a timely fashion to
allow that party to take the necessary steps to seek a protective order or to
otherwise take the necessary actions to maintain the confidentiality of this
Confidential Information.

                     Notwithstanding the provisions of this Section 9, each
party may, to the extent necessary, disclose the Confidential Information of the
other party to its Affiliates, directors, officers, employees, consultants,
vendors and clinicians under written agreements of confidentiality at least as

                                      LIENS

Under a Revolving Credit and Security Agreement dated March 30, 1998 between
Warner Chilcott, Inc. and PNC Bank, National Association (the "Credit
Agreement"), Warner Chilcott pledged certain assets as collateral for such loan.
The assets pledged include Warner Chilcott's rights to the Vectrin(R) trademark
as well as its inventory of Vectrin samples and inventory (including without
limitation raw materials and work in process). To perfect PNC's security
interest in the Vectrin(R) trademark under the Credit Agreement, Warner Chilcott
also entered into a Trademark Collateral Assignment and Security Agreement dated
March 30, 1998. PNC has agreed to release all liens and security interest in the
Vectrin(R) trademark and inventory and will execute all documents necessary
thereto so that Medicis will obtain clear title to such assets at the closing.

                                   LITIGATION

1.         Natasha Frazier v. Lederle Laboratories, American Cyanamid, Warner
           Chilcott, Inc., Warner Lambert Company, R.M. McMillin, M.D. and Roane
           County Family Practice, Circuit Court for Roane County, Tennessee, No
           11620

                     Product liability suit. Plaintiffs are legal parents of a
                     12 year old female decedent, Natasha Frazier. Complaint
                     alleges that Ms. Frazier's death was attributable to
                     medical malpractice and failure of pharmaceutical companies
                     to warn of risks of minocycline. Warner Chilcott's
                     insurance company has assumed full defense of the claim.

2.         Warner Chilcott, Inc. v. Medicis Dermatologies, Inc., United States
           District Court of New Jersey, Hon. Alfred M. Wolin,
           Civ. Act. No. 98-4085

                     Warner Chilcott is plaintiff in this suit alleging damage
                     due to certain advertising and statements made by
                     defendant.

3.         Claudia Wojnarowicz Claim: On June 3, 1999, the law firm of Goforth
           Lewis & Williams in Houston, Texas, wrote the CEO of Warner Chilcott
           notifying it that it had been retained by Ms. Wojnarowicz to
           represent her in her claim of personal injuries arising out of
           minocycline, 100 mg. capsules. [REDACTED] Upon advise of outside
           counsel, the Company wrote to Goforth on July 27 asking for
           additional information so that this claim could be examined in more
           detail. As of August 20, 1999, no reply has been received. It is
           unclear at this point whether this claim will ripen into a lawsuit.
