     (b)   If the total royalty payable to PPTI by FEMCARE for the first
           Marketing Year and each subsequent Marketing Year is less than the
           applicable "Minimum Royalty" for that Marketing Year, FEMCARE shall
           within 90 days of the end of each such Marketing Year pay to PPTI
           (subject to paragraph (e) of this Article 4.02) a sum equal to the
           applicable Minimum Royalty less the actual royalty payable. At any
           time after the fifth Marketing Year, FEMCARE may notify PPTI that it
           is not going to make such payment in respect of any Marketing Year
           commencing after such fifth Marketing Year in which case the license
           granted pursuant to clause 2.01 shall at the expiry of such 90 day
           period become non-exclusive to FEMCARE for the remainder of the term
           of this Agreement.

           The applicable Minimum Royalty shall be as follows:

           Marketing Year                Minimum Royalty

               First                     ***

               Fifth and thereafter      ***

     Provided that if the rate of royalty payable under Article 4.02 is reduced
     pursuant to any provision of this Agreement or FEMCARE is permitted by this
     Agreement to set off or deduct any monies against any royalty payable to

     rate of royalty had not been so reduced and such set off or deduction had
     not been made.

     Provided further that in any relevant Marketing Year such applicable
     Minimum Royalty shall be reduced by the extent to which FEMCARE failed to
     sell or procure that sale of sufficient Products to avoid having to pay
     such Minimum Royalty directly as a result of any material breach of this
     Agreement or the Supply Agreement by PPTI (and for this purpose force
     majeure under either Agreement which prevents PPTI from being in breach
     thereof shall be disregarded, and in the case of a force majeure affecting
     FEMCARE or its performance on  which such Minimum Royalty for such
     Marketing Year depends is affected by the force majeure, the Minimum
     Royalty shall be reduced by such fair amount.

     Provided, however, that no Minimum Royalty shall be payable in respect of
     any period during which Product cannot be Commercialized as a result of any
     inherent defect in the Product, any Recall required by any applicable
     regulatory body that is not specific to identified Product lots that are
     replaced within a reasonable period of time, or the Product being found to
     not be safe for use in humans.

     (c)   If the applicable royalty rate exceeds the permissible rate
           established in a Territory for royalty payments in that Territory or
           royalty remission from that Territory, as the case may be, the rate
           of royalty shall not exceed the established permissible rate and
           FEMCARE shall pay the difference between the royalty due and the
           royalty at the established permissible rate unless said payments made
           outside the Territory are illegal. In such event, the parties shall
           negotiate in good faith such equitable adjustments to other payments
           and financial obligations as may be appropriate so that the parties
           realize the intended benefits of this Agreement.

     (d)   Any Affiliate of FEMCARE may pay any royalty obligations of FEMCARE
           under this Agreement directly to PPTI with the same effect as if the
           payment had been made by FEMCARE.

     (e)   All payments under this Agreement shall be made without deduction of
           any taxes, charges, or duties except for such taxes, charges or
           duties which are required under any applicable laws to be deducted.
           Any tax deducted by FEMCARE or

                                       18
<PAGE>

           any Affiliate of FEMCARE under the laws of any foreign country for
           the account of PPTI shall be promptly paid to the proper governmental
           authority, and FEMCARE or its Affiliates shall furnish PPTI with
           proof of payment of such tax together with official or other
           appropriate evidence issued by the appropriate governmental authority
           sufficient to enable PPTI to document claim for income tax credit in
           respect to any sum so deducted. Any such tax required to be withheld
           shall be an expense of and borne solely by PPTI.

     (f)   FEMCARE shall keep accurate books and records of all payments due to
           PPTI. Said books of account shall be kept at FEMCARE's principal
           place of business or the principal place of business of an
           appropriate Affiliate to which this Agreement relates.

     (g)   PPTI shall have the right to nominate an independent accountant
           acceptable to and approved by FEMCARE (which approval shall not be
           unreasonably withheld) who shall have access to FEMCARE's records on
           reasonable notice during reasonable business hours for the purpose of
           verifying, at PPTI's expense (except as provided below), the royalty
           payable as provided for in this Agreement for the three preceding
           years, but this right may not be exercised more than once in any
           year. PPTI shall solicit or receive only information relating to the
           accuracy of the royalty report and the royalty payments made. Any
           underpayment of royalty shall be paid within thirty (30) days of the
           delivery of a detailed written accountants report to FEMCARE. Any
           overpayment of royalty shall be credited to the next royalty payment
           due from FEMCARE. If no further royalty payments will be due then a
           refund will be made within sixty (60) days of the audit. If the
           accountant's report shows an underpayment of royalties of five
           percent (5%) or more, FEMCARE shall reimburse PPTI for all cost and
           expense of the accountant's report.

     (h)   FEMCARE shall deliver to PPTI written reports of Net Sales during the
           preceding Calendar Quarter on or before the thirtieth (30th) day
           following the end of each Calendar Quarter. Such reports shall
           include a calculation of the earned royalty due and shall be
           accompanied by the monies due. If no earned royalties are due, then
           FEMCARE shall indicate such on its written report.

           Price Competition and Patent Term Restoration Act of 1984, the
           Supplementary Certificate of Protection of the Member States of the
           European Common Market and other similar measures in any other

      (b)  Without limiting the foregoing, PPTI agrees to notify FEMCARE
           promptly upon receipt of any PMA approval to Commercialize Product in
           the United States and PPTI agrees to file an application for patent
           extension in the U.S. Patent and Trademark Office within the sixty
           (60) day period following the receipt of such PMA approval.

14.01 (a)  If, as a result of the manufacture or Commercialization of the
           Product in the Territories pursuant to this Agreement and the Supply
           Agreement, PPTI and its Subsidiaries or FEMCARE and/or its
           Affiliates, distributors or sub-licensees, are sued for patent
           infringement or infringement of other intellectual property rights or
           threatened with such a lawsuit or other action by a third party, PPTI
           and FEMCARE shall promptly meet to analyze the infringement claim and
           avoidance of same.

      (b)  If following such meeting the parties fail to agree on a joint
           program of action, including how the costs of any such action are to
           be borne and how any damages or other sums received from such action
           are to be distributed, then FEMCARE shall be entitled to take action
           against the third party at its sole expense and it shall be entitled
           to all damages or other sums received from such action. PPTI shall
           agree to be joined in any suit to enforce such rights subject to
           being indemnified and secured in a reasonable manner as to any costs,
           damages, expenses or other liability and shall have the right to be
           separately represented by its own counsel at its own expenses.

      (c)  If it is necessary to obtain a license from such third party, PPTI
           and FEMCARE in negotiating such a license shall in the extent
           practicable use their reasonable efforts to minimize the license fees
           and/or royalty payable to such third party.

      (d)  If FEMCARE or its Affiliates, distributors or sub-licensees shall be
           obligated to pay a license fee and/or royalty to a third party under
           such licence as the result of the Commercialization of the Product or
           the use of Patents or Know-How then PPTI shall elect within ten (10)
           days of the execution of the license with such third party to:

           (i)     pay all fees and expenses associated with obtaining and
                   maintaining the license; or

           (ii)    to have the royalties specified in Article 4.02 reduced by
                   ***.

      (e)  FEMCARE shall be entitled to deduct from up to one-half of the
           royalties payable under clause 4.02 any sums paid to third parties
           (including without limitation damages, payments in settlement of
           litigation and reasonable cost and expenses incurred in relation to
           any alleged or actual infringement of third party rights in the
           manufacture or

           Commercialization of any product; provided that such payments are
           specifically approved, in advance, by PPTI, such approval to not be
           unreasonably withheld or delayed).

14.02 (a)  In the event that there is infringement of a Patent involving the
           Product by a third party in the Territories, PPTI and FEMCARE shall
           notify each other in writing to that effect immediately upon becoming
           aware of the same, including if practicable with said written notice
           evidence establishing a case of infringement by such third party.

      (b)  FEMCARE shall have the right, in its sole discretion, but not the
           obligation to bring such suit at its own expense and in its own name,
           if possible, or jointly in its name and in the name of PPTI or if
           necessary in PPTI's sole name.

      (c)  FEMCARE shall bear all the expenses of any suit brought by it and
           shall retain all damages or other monies awarded or received in
           settlement of such suit; provided, however, that at its option
           exercised by notice in writing to FEMCARE before it commences such
           suit PPTI may contribute to the expenses of any such suit and, in
           such event, FEMCARE and PPTI shall share proportionately to their
           respective contributions all damages or other monies awarded or
           received in settlement of such suit.

      (d)  PPTI will cooperate with FEMCARE in any such suit and shall have the
           right to consult with FEMCARE and, if it elects pursuant to the
           proviso to paragraph (c) of this Article, to be separately
           represented by its counsel at its own expense.

14.03 (a)  In the event that there is infringement of a patent of a Joint
           Invention jointly owned by the parties outside the grant provided to
           FEMCARE under Article 3.01 by a third party, PPTI and FEMCARE shall
           notify each other in writing to that effect immediately upon becoming
           aware of the same, including if practicable with said written notice
           evidence establishing a case of infringement by such third party.

                                       37
<PAGE>

      (b)  PPTI and FEMCARE shall meet to analyze the infringement claim, the
           evidence of same and attempt to agree upon a suitable approach for
           addressing said infringement.

15    ARBITRATION OF DISPUTES

15.01 Excepting only actions and claims relating to actions commenced by a third
      party against PPTI or FEMCARE (including, without limitation, for injuries
      caused by a Product or in respect to a trademark or patent infringement
      claim), any controversy or claim arising out of or relating to the terms
      and conditions of this Agreement, or the decision to agree upon these
      terms, or the breach thereof, including questions of validity,
      infringement, or termination hereof, shall be settled exclusively by
      arbitration in accordance with the rules of the American Arbitration
      Association. If such controversy or claim relates to patent validity or
      infringement, then the Patent Arbitration Rules of the AAA shall apply;
      otherwise the International Arbitration Rules of the AAA shall apply.
      Notwithstanding the foregoing to the contrary or in the arbitration rules
      invoked or in this Section 15, the parties retain the right to request a
      judicial authority to invoke interim measures of protection, and such
      request shall not be deemed incompatible with this agreement to arbitrate
      or a waiver of the right to arbitrate.

15.02 There shall be one (1) arbitrator to be mutually agreed upon by the
      parties and to be selected from the Regional Panel of Distinguished
      Neutrals. If the parties are unable to agreeupon such an arbitrator who is
      willing to serve within ten (10) days of receipt of the demand by the
      other party, the parties shall within three (3) days select one of the
      five largest international public accounting firms (excluding those
      providing services to the parties) and engage the managing partner or
      senior officer of its New York City office to designate a partner of such
      firm to serve as the arbitrator. Failing that, then the AAA shall appoint
      an arbitrator willing to serve from the Regional Panel of Distinguished
      Neutrals, or if no such panel exists, then from an appropriate AAA panel.
      It shall be the duty of the arbitrator to set dates for preparation and
      hearing of any dispute and to expedite the resolution of such dispute.

                                       38
<PAGE>

15.03 (a)  The arbitration shall be held in the City of New York, State of New
           York, U.S.A. and the arbitrator shall apply the substantive law of
           Delaware except that the interpretation and enforcement of this
           arbitration provision shall be governed by the Federal Arbitration
           Act.

      (b)  The arbitrator shall permit and facilitate discovery, which will be
           conducted in accordance with the Federal Rules of Civil Procedure,
           taking into account the needs of the parties and the desirability of
           making discovery expeditious and cost-effective.

      (c)  The arbitrator will set a discovery schedule with which the parties
           will comply and attend depositions if requested by either party.

      (d)  The arbitrator will entertain such presentation of sworn testimony or
           evidence, written briefs and/or oral argument as the parties may wish
           to present, but no testimony or exhibits will be admissible unless
           the adverse party was afforded an opportunity to examine such witness
           and to inspect and copy such exhibits during the pre-hearing
           discovery phase.

      (e)  The arbitrator shall among his other powers and authorities, have the
           power and authority to award interim or preliminary relief.

      (f)  The arbitrator shall not be empowered to award either party exemplary
           or punitive damages or any enhanced damages for willful infringement
           and the parties shall be deemed to have waived any right to such
           damages.

      (g)  A qualified court reporter will record and transcribe the proceeding.

      (h)  The decision of the arbitrator will be in writing and judgment upon
           the award by the arbitrator may be entered in any court having
           jurisdiction thereof.

      (i)  Prompt handling and disposal of the issue is important. Accordingly,
           the arbitrator is instructed to assume adequate managerial initiative
           and control over discovery and other aspects of the proceeding to
           schedule discovery and other activities for substantially continuous
           work, thereby expediting the arbitration as much as is deemed
           reasonable to him, but in all events to effect a final award within
           365 days of the arbitrator's selection or appointment and within 20
           days of the close of evidence.

      (j)  The proceedings shall be confidential and the arbitrator shall issue
           appropriate protective orders to safeguard both parties' confidential
           information.

                                       39
<PAGE>

      (k)  The fees of the arbitrator and the AAA shall be paid as designated by
           the arbitrator or, if he shall not so designate, they shall be split
           equally between the parties.

17.01 (a)  Subject to compliance with paragraph (b) of this Article 17 any
           delays in or failure of performance by either party under this
           Agreement shall not be considered a breach of this Agreement if and
           to the extent caused by any occurrences beyond the reasonable control
           of the party affected, including but not limited to: acts of God;
           acts, regulations or laws of any government; strikes or other

      this Agreement shall have the right, power or authority to act or create
      any obligation, express or implied, on behalf of the other party. This

20.02 PPTI represents and warrants to FEMCARE that the following statements are
      true and accurate in all material respects as follows:

      (a)  To its knowledge and belief, it has sufficient right and title to and
           ownership of, free and clear of all liens, claims and encumbrances of
           any nature, the Intellectual Property to grant to FEMCARE the various
           rights and Licenses granted to FEMCARE under this Agreement;

      (b)  It has not done and subject to clause 23, will not do nor agree to do
           during the term of this Agreement, any of the following things if to
           do so would be materially inconsistent with the exercise by FEMCARE
           of the rights granted to it under this Agreement, assign, mortgage,
           hypothecate, or otherwise transfer any of the Patents or any of its
           rights or obligations under this Agreement;

      (c)  It is not aware that any third party owns any rights in the

      (e)  It has reasonable grounds for believing that the Product in its
           present form will constitute substantially the Product for
           Commercialization in the Territories;

      (f)  There is no information known to PPTI concerning the Product not
           previously incorporated in the IDE *** or disclosed to FEMCARE which
           indicates that it may not be safe for administration to humans or
           that the development and Commercialization of the Product would not
           be commercially successful.

21    INTEGRATION AND CONFLICT

21.01 (a)  It is the mutual desire and intent of the parties to provide
           certainty as to their future rights and remedies against each other
           by defining the extent of their mutual undertakings provided herein.

           Agreement and Escrow Agreement incorporated the representations,
           warranties, covenants, commitments and understandings on which they
           have relied in entering into this Agreement and, except as provided
           for herein and in the Supply Agreement and Escrow Agreement, neither
           party has made any undertaking or other commitment to the other
           concerning its future activities. Accordingly, this Agreement and the
           related Supply Agreement and Escrow Agreement:

           (i)     constitute the entire agreement and understanding between the
                   parties with respect to the subject matter contained herein,
                   and there are no promises, representations, conditions,
                   provisions or terms related thereto other than as set forth
                   in this Agreement and the related Supply Agreement and Escrow
                   Agreement; and

           (ii)    supersede all previous understandings and agreements, and
                   representations between the parties, whether written or oral,
                   relating to the subject matter.

      (b)  The parties may from time to time during the term of this Agreement
           modify any of its provisions by mutual agreement in writing.

      (c)  The parties agree that each has had the opportunity to be represented
           by counsel of it choosing including the negotiations that preceded
           this Agreement.

      (d)  In the event of any conflict between the provisions of this Agreement
           and the Supply Agreement, unless expressly stated in this Agreement,
           the provisions of this Agreement shall prevail.

22    GOVERNING LAW

22.01 This Agreement shall be construed and the rights of the parties shall be
      determined in accordance with the substantive laws of the State of
      Delaware, without regard to its conflict of laws principles, except that
      the Arbitration provisions contained herein shall be governed as stated in
      Section 15.

23    ASSIGNMENT

23.01 Except as specifically provided herein each party in its sole discretion,
      may assign or transfer all or a portion of its rights under this Agreement
      to any of its Affiliates, or designate or cause any Affiliate to have the
      benefit of all or a portion of its rights hereunder; provided, however,
      that any such party shall remain liable for the performance by its
      Affiliate under this Agreement. Also, either party may assign this
      Agreement to a party purchasing substantially all of the assets or
      operations of such party. Except as herein provided, neither party shall
      assign or otherwise transfer this Agreement or any part hereof to any
      third party without the prior written permission of the other party.

24    BANKRUPTCY

24.01 All rights and licenses granted under or pursuant to this Agreement by a
      party acting as licensor to the other party as licensee are, and shall
      otherwise be deemed to be, for purposes of Section 365(n) of Title 11,
      U.S. Code (the "Bankruptcy Code") licenses of rights to "intellectual

                                       45
<PAGE>

      property" as defined under Section 101(60) of the Bankruptcy Code. The
      parties agree that a licensee of such rights under this Agreement, shall
      retain and may fully exercise all of its rights and elections under the
      Bankruptcy Code. The licensor of such rights agrees during the term of
      this Agreement to create and maintain current copies or, if not amenable
      to copying, detailed descriptions or other appropriate embodiments, of all
      such intellectual property. The parties further agree that, in the event
      of the commencement of a bankruptcy proceeding by or against the licensor
      under the Bankruptcy Code, the licensee shall be entitled to a complete
      duplicate of (or complete access to, as appropriate) any such intellectual
      property and all embodiments of such intellectual property, and same, if
      not already in its possession, shall be promptly delivered to licensee (i)
      upon any such commencement of a bankruptcy proceeding upon written request
      therefor by the licensee, unless licensor elects to continue to perform
      all of its obligations under this Agreement, or [(ii) if not delivered
      under (i) above, upon the rejection of this Agreement by or on behalf of
      licensor upon written request therefor by licensee.
