2.1.  Undertaking.
      -----------

      (a)   Subject to the limitations contained herein, SEARLE or its
            Affiliates hereby agrees to Package or to have Packaged WATSON's
            orders for the Products in the Territory and WATSON agrees to pay
            SEARLE for the quantity of Products so Packaged in accordance with
            this Agreement. However, for the Product, Nor Q.D., SEARLE hereby
            only agrees to conduct the required testing according to the Quality
            Responsibilities in Schedule 6.1. WATSON is responsible for all
            other aspects of Packaging Nor Q.D. SEARLE shall not be obligated to
            Package Products in excess of the capacity limitations described in
            Sections 3.1 and 3.2. For the duration of this Agreement, WATSON
            hereby grants to SEARLE a royalty-free license and right in the
            Territory to use such of the Assets as are necessary or useful to
            SEARLE in fulfilling its obligations under this Agreement.

      (b)   In addition, SEARLE or its Affiliates agree to conduct bulk tablet
            testing of the Products or to have such testing conducted and will
            report the results of these tests to WATSON within five (5) working
            days of receiving the results of these tests. SEARLE or its designee
            will conduct the tests in accordance with the Bulk Tablet Testing
            Specifications contained in Schedule 1.6.

      (c)   WATSON will review the results of the bulk tablet tests and in
            WATSON's sole discretion determine which lots of bulk Product are
            acceptable for release to SEARLE for Packaging. For each lot of bulk
            Product that WATSON releases to SEARLE for Packaging, WATSON shall
            provide SEARLE with written authorization to accept those lots of
            bulk Product. Without such written authorization from WATSON, SEARLE
            will not accept shipment of these lots of bulk Product.

      (d)   The parties acknowledge that any of SEARLE's obligations hereunder
            may be carried out, at SEARLE's election, by third party
            manufacturers appropriately qualified under all Laws to perform the
            Packaging obligations hereunder in compliance with the
            Specifications and all Laws; provided that SEARLE's use of any third
            party manufacturer shall require WATSON's


                                       5



            prior written consent, which consent shall not be unreasonably
            withheld, and the written agreement by the third party to abide by
            and comply with the terms of this Agreement. Notwithstanding the
            above, the use of any third party manufacturer shall not relieve
            SEARLE of its obligations under this Agreement.

      (e)   WATSON will supply SEARLE, free of charge, with sufficient released
            Product in bulk form at least sixty (60) days before any finished
            Product delivery date set pursuant to Article 3 for SEARLE to comply
            with its Packaging commitments to WATSON under this Agreement.

2.2.  Price and Payment.
      -----------------

      (a)   During the first Contract Year, the prices for Packaging the
            Products are set out in Schedule 2.2(a). Thereafter, the prices
            shall be adjusted as provided in subsection (c) below.

      (b)   Except as otherwise provided herein, including an event of Force
            Majeure affecting either party, during each Contract Year of this
            Agreement, WATSON shall purchase a minimum quantity of Products
            equal to US $(----) ("Minimum Quantity"). If in any such Contract
            Year, WATSON fails to purchase such Minimum Quantity, then WATSON
            shall pay SEARLE an amount equal to (----)% of the difference
            between US $(----) and the total price for all Products purchased by
            WATSON for delivery in such Contract Year. Purchase Orders issued by
            WATSON in 2001 for Product to be delivered in 2001 will not be
            included in the Minimum Quantity for 2002 even if Product so ordered
            is not delivered until 2002. Such Minimum Quantity will include the
            purchases made by WATSON under the Ogestrel Agreement for Ogestrel
            and Low-Ogestrel during the applicable Contract Year. It is agreed
            and understood that these liquidated damages are intended to
            compensate SEARLE for its lost profits and overhead costs which are
            difficult to calculate and project due to uncertainties in
            scheduling its manufacturing operations, and in no way are such
            liquidated damages to be construed as a penalty for WATSON's breach.

      (c)   By December 1st of each Contract Year, SEARLE shall provide WATSON
            with written notice of the prices for the following Contract Year.
            Effective January 1 of each year, SEARLE may increase its prices for
            the Product by an amount equal to increases in the Producer Price
            Index for Pharmaceutical Preparations, PCU2834, as published by the
            U.S. Bureau of Labor Statistics, over the previous twelve (12) month
            period, September to October. Price increases for the Product shall
            not exceed (----)% annually. Price changes will take effect January
            1 of each year and shall be effective for one year. These price
            changes will apply to any Purchase Orders issued by WATSON in the
            previous Contract Year provided the Purchase Order specifies a
            delivery date after January 1 of the current Contract Year. In the
            event the verifiable cost of SEARLE's packaging materials increases
            by more than (----)%


                                       6



            in a Contract Year, however, SEARLE may adjust the Product(s) price
            to WATSON to reflect these increased packaging component costs.

      (d)   The Products will be shipped to a location in the Territory
            designated by WATSON, FCA (Incoterms 2000) SEARLE's manufacturing
            plant. Title and risk of loss shall pass to WATSON upon delivery of
            the Products to the common carrier.

      (e)   WATSON will pay in US currency for each shipment of Products within
            (----) days after the shipment of the Product(s).

ARTICLE 3. FORECASTS AND ORDERS

3.1.  Forecasts.
      ---------

      (a)  On a monthly basis, WATSON will provide SEARLE with a written (----)

           (the "(----) Month Forecast"), or the remaining months of the
           contract, if less than (----) months left in the contract. Except as
           may be provided otherwise in this Section 3, the forecast for each
           Contract Year will be limited to an amount not greater than (----)%
           of the forecast for the prior Contract Year.

           Forecast") shall be firm and shall not have been changed from the
           forecasted amounts for the same calendar months contained in the
           prior (----) Month Rolling Forecast.

3.2.  Permitted Amount to be Ordered. WATSON shall submit a purchase order to

      ------------------
      (----) Batch of such Product with larger orders being in whole number
      multiples of a Batch. A Batch of bulk Product may be split between trade
      and sample presentations as long as the whole Batch is consumed in
      packaging within one month's time.

3.4.  Failure to Supply.
      -----------------

      (a)   In the event SEARLE fails or is unable to Package or conduct testing
            in accordance with the Bulk Tablet Testing Specifications or has
            reason to believe that it will be unable to so test or to Package
            the quantities of the Products ordered by WATSON to meet WATSON's
            requirements (within


                                       7



            the limits described in Section 2.1 above and within thirty (30)
            days after the delivery date set forth in the applicable purchase
            order), WATSON may (i) purchase or obtain so much as to meet its
            requirements or any portion thereof from any other source, and/or
            (ii) to the extent permitted by law, Package or have Packaged the
            same under the applicable Specifications and quality control
            procedures. In such event, SEARLE shall provide WATSON or WATSON's
            contract manufacturer with all documents, data and other information
            necessary or useful for Packaging the Products at no cost for so
            long as SEARLE is unable to supply sufficient quantities of the
            Products to meet WATSON's requirements. Any such quantities Packaged
            by a secondary source pursuant to this Paragraph shall nonetheless
            be credited against the WATSON's Minimum Quantity purchase
            obligation under Paragraph 2.2(b).

      --------------
      in accordance with the Specifications and all Laws.

      ----------------
      the Specifications at all times shall be in compliance with the Product
      Registration, from time to time with SEARLE's consent which shall not be
      unreasonably withheld, but not more often than (----) per year unless
      required by the FDA or other US government agency. All such changes shall
      be communicated to SEARLE in writing, after which the parties shall agree
      on the date of implementation of such changes as soon as reasonably
      practicable. If any such change results in increased Packaging, testing
      costs or obsolescence of any materials specifically purchased by SEARLE
      for Packaging of the Products under this Agreement prior to being notified
      in writing by WATSON of the change in the Specifications, WATSON shall
      reimburse SEARLE for any such increased costs and the actual out-of-pocket
      cost of all such materials except to the extent the quantity of such
      materials exceeds requirements greater than the previous (----) months of
      WATSON's forecasts. Upon being reimbursed for obsolete material and at
      WATSON's written request, SEARLE shall promptly ship any such materials to
      a location designated by WATSON or destroy such materials at WATSON's
      expense. If any such change or proposed change to the Specifications
      results in costs and expenses to SEARLE, WATSON shall promptly reimburse
      all such reasonable documented out-of-pocket costs and expenses.

ARTICLE 5. PACKAGING MATERIALS

5.1.  Supply. SEARLE will supply all materials required to Package the bulk
      ------

6.4.  Quality Issues Bulk Product. Any quality, safety or similar issues related
      ---------------------------
      to the bulk Product supplied by WATSON to SEARLE are WATSON's
      responsibility to resolve; provided, however, that any quality, safety or
      similar issues related to the bulk Products caused by SEARLE's failure to
      comply with the terms of this Agreement or Laws, or SEARLE's negligence or
      willful misconduct shall be the responsibility of SEARLE, such
      responsibility to include, without limitation, the obligation to reimburse
      WATSON for loss or damage to the bulk Product. For any Product which
      cannot be released due to quality or safety issue related to the bulk
      Product which is the responsibility of WATSON hereunder, WATSON shall
      reimburse SEARLE for the direct cost of manufacture of the affected
      Product, said direct cost of manufacture to be calculated by adding the
      actual cost of : a) Packaging materials and supplies used to Package the
      affected Products; b)Wages of those employees directly employed in the
      packaging of the affected Products; and, (c) That portion of SEARLE's

      received by either of them to the other no later than three (3) days
      following receipt and shall provide assistance in investigating such
      complaints as may be reasonably requested. Each party shall designate a
      representative who will handle Product complaint activities for such party
      and coordinate such activities with the other party.

6.6.  Recalls Relating to Products. Recalls of the Products shall be the
      ----------------------------
      responsibility of WATSON. The party desiring to initiate a recall shall
      notify the other and, immediately thereafter, both parties shall discuss
      appropriate alternatives, including whether a recall is required and the
      method of implementing a recall. SEARLE shall cooperate with WATSON in the
      event of any recall, field alert or similar event and provide such
      assistance in connection therewith as WATSON may reasonably request. The
      costs of any such recall or similar event shall be borne by WATSON, except
      if the recall resulted from SEARLE's negligence, or breach of this
      Agreement, in which case SEARLE shall reimburse WATSON for the costs and
      expenses reasonably borne and paid by WATSON to effect the recall.

6.7.  Inspection. SEARLE agrees to permit WATSON's designated representatives to
      ----------
      whom SEARLE has no reasonable objections to inspect SEARLE facilities at
      which the Products are Packaged, stored or tested for the purpose of
      determining compliance with applicable Law and the Specifications at
      reasonable times after reasonable notice during regular business hours.

6.8.  Quality Control Evaluation. Within (----) days after receipt of each
      --------------------------
      shipment, WATSON will inspect and make a quality control evaluation of
      such shipment (which shall include a certificate of analysis). In the
      event any shipment or part thereof fails, or there is manifest cause for
      WATSON to reasonably believe that any shipment or part thereof fails to
      conform to the Packaging Specifications or shall have been Packaged or
      shipped under conditions which do not comply with the FDA requirements or
      the provisions of this Agreement, WATSON may reject the same by giving
      written notice to SEARLE within the (----) day period, specifying the
      manner in which it fails to meet the requirements. SEARLE shall have
      (----) days within which to accept or reject WATSON's claims.

6.9.  Disputes. In the event of any dispute as to whether any shipment of
      --------
      Products fails in whole or part to meet the Packaging Specifications, such
      dispute shall be promptly resolved by an independent testing organization
      of recognized repute within the US pharmaceutical industry mutually agreed
      upon by the parties, the appointment of which shall not be unreasonably
      withheld or delayed by either party. Until any dispute is resolved, WATSON
      will not dispose of any


                                       10



      nonconforming shipment without prior written authorization from and
      agreement with SEARLE. The fees and costs of such testing organization
      shall be borne by the party whose position is not sustained by the testing
      organization.

6.10. Replacement Products. If any Products shipped hereunder are rejected by
      --------------------
      WATSON, SEARLE agrees to ship as soon as reasonably possible after notice
      of such rejection (or if there is a dispute with regard to the rejection,
      after notice of the determination of the independent testing organization)
      replacement Products either newly packaged or, with the consent of WATSON,
      reworked from the rejected shipment using an FDA approved procedure with
      respect thereto. SEARLE's requirement to ship replacement Product is
      entirely contingent on first receiving sufficient replacement bulk

      proceeding made or brought against such party by a third party (i) as a
      result of WATSON's use, promotion, sale and/or distribution of the
      Products except to the extent such liability arises from SEARLE's breach

      provided herein, the Claimant shall have the full right to conduct the
      defense, settle or otherwise dispose of the claim at the Indemnitor's
      expense. The Indemnitor shall have the right to settle or

ARTICLE 10. TERM AND TERMINATION

10.1. Term. The term of this Agreement shall be, unless terminated earlier as

10.2. Termination by Either Party. Either party shall have the right to
      ---------------------------
      terminate this Agreement immediately upon written notice to the other:

      (a)   if the other party is dissolved or liquidated, files or has filed
            against it a petition under any bankruptcy or insolvency law, makes
            an assignment for the benefit of its creditors or has a received
            appointed for all or substantially all of its property and is not
            withdrawn within sixty (60) days of appointment; or


                                       13



      (b)   if the other party shall commit any material breach (whether
            remediable or not) of its obligations under this Agreement and, if
            remediable, shall fail to remedy the breach within sixty (60) days
            after receipt of written notice from the non-breaching party

10.3  Termination With Notice. WATSON shall be entitled to terminate this
      -----------------------
      Agreement in its entirety, with an effective date of December 31, 2002, by
      giving written notice to SEARLE on or before July 1, 2002. In the event,
      WATSON submits a written request to SEARLE by July 1, 2002, that it would
      like to terminate this Agreement only as related to an individual Product
      or Products, effective December 31, 2002, SEARLE will have 1 month to
      respond to this request. No later than August 1, 2002 Pharmacia will

      This decision will be at Pharmacia's sole discretion and if WATSON does
      not receive a response from SEARLE by August 1, 2002, SEARLE will be
      deemed to have rejected WATSON's request for a partial termination.

10.4  Without Prejudice. Termination of this Agreement, due to the fault of
      -----------------

      Agreement, SEARLE will complete work on all in process Products. WATSON
      will pay SEARLE the price determined pursuant to Section 2 for Products
      Packaged by SEARLE. In addition, WATSON shall reimburse SEARLE for the
      cost of any packaging and labeling materials remaining in SEARLE's
      inventory, which packaging and labeling material will be promptly
      delivered to WATSON at a place of WATSON's designation. However, in no
      event shall the quantity of Products and packaging/labeling materials to
      be purchased by WATSON under this provision after expiration or
      termination exceed WATSON's forecasts for the preceding six (6) month
      period.

12.4. Entire Agreement. This Agreement, together with any Schedules hereto and
      ----------------
      the Asset Purchase Agreement, constitute the entire Agreement between the
      parties concerning the subject matter hereof; it may not be modified or
      amended except in writing signed by all parties. All agreements or
      arrangements (if any) among the parties executed prior to the date hereof
      (except for the Asset Purchase Agreement), whether written or oral,
      relating to the subject matter hereof are hereby canceled and superseded.

12.5. Schedules. The Schedules (as amended from time to time by agreement of the
      ---------
      Parties in writing) form part of this Agreement and shall have the same
      force and effect as if expressly set out in the body of the Agreement and
      any reference to the Agreement shall include the Schedules. To the extent
      that there is conflict between or ambiguity relating to, on the one hand,
      any or all of the Schedules and, on the other, the remainder of this
      Agreement, the wording of the Agreement shall prevail.

12.6. Headings. Headings are inserted for convenience and shall not by
      --------
      themselves determine the interpretation of this Agreement.

12.7. Counterparts. This Agreement may be executed in counterparts, each of
      ------------
      which shall be deemed an original but together constituting one agreement.

12.8. Assignment. Except as otherwise provided in this Section, neither party
      ----------
      may assign or delegate any right or obligation hereunder without the prior
      written consent of the other party, which consent shall not be
      unreasonably withheld, and any attempted assignment or delegation in
      violation hereof shall be void. WATSON and SEARLE may each assign all or
      part of its rights and obligations hereunder to an Affiliate on notice to
      and without the necessity of securing the other party's consent, subject
      to and for so long as such assignee remains an Affiliate of the assignor.
      In addition, either party may assign all of its rights and obligations
      hereunder to a purchaser of all or substantially all of the assets or
      business to which this Agreement relates.

12.9. Waiver of Default. No waiver of any default hereunder by any party or any
      -----------------
      failure to enforce any rights hereunder shall be deemed to constitute a
      waiver of any subsequent default with respect to the same or any other
      provision hereof. No waiver shall be effective unless made in writing with
      specific reference to the relevant provision(s) of this Agreement and
      signed by a duly authorized representative of the party granting the
      waiver.

12.10. Not for Benefit of Creditors. The provisions of this Agreement are
       ----------------------------
      intended only for the regulation of relations between the parties. Except
      as expressly provided in Article 8 (and then subject to the limitations
      stated in such Article), this Agreement is not intended for the benefit of
      any person, firm or entity not a party


                                       16



      hereto and no rights are granted to such third parties hereunder.

12.11. Force Majeure. If any party is prevented from performing any obligation
       -------------
      hereunder by reason of fire, explosion, strike, labor dispute, casualty,
      accident, lack or failure of transportation facilities, flood, war, civil
      commotion, acts of God, any law, order or decree of any government or
      subdivision thereof or any other cause beyond the reasonable control of
      such party ("Force Majeure), then such party shall be excused form
      performance hereunder to the extent and for the duration of such
      prevention, provided it first notifies the other party in writing of such
      prevention. The foregoing shall not apply to any prevention due to any
      governmental regulatory action resulting directly from the fault of
      SEARLE.

12.12. Publicity. Neither SEARLE nor WATSON, nor any Affiliate thereof, will
       ---------
      issue or cause publication of any press release or other announcement or
      public communication with respect to this Agreement or the transactions
      contemplated hereby without the prior written consent of the other party,
      which consent will not be unreasonably withheld or delayed.

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