ITEM 2.           ACQUISITION OR DISPOSITION OF ASSETS.

 On October 16, 1997, Watson Laboratories, Inc., a subsidiary of Watson
Pharmaceuticals, Inc. ("Watson"), purchased the U.S. rights to certain branded
off-patent and proprietary oral contraceptive products from G. D. Searle & Co.
and SCS Pharmaceuticals ("Searle"). At closing, Watson paid $80.0 million from
available cash on hand. This amount includes a $5.0 million payment related to
the achievement of certain events between the signing and the closing of the
transaction. Watson also agreed to acquire the U.S. rights to certain future
additional oral contraceptive products from Searle (the "Future Products"), upon
achievement of certain events, which include in certain instances, approval by
the U.S. Food and Drug Administration. The aggregate acquisition cost for all of
the Future Products, if the products are acquired prior to July 1, 1999, is
$93.5 million. In addition to the acquisition cost of the Future Products,
Watson also agreed to make contingent payments to Searle based on the
achievement of certain events, including but not limited to, future net sales of
certain products during the period from January 1, 2000 to December 31, 2004.

Copies of the agreements between Watson and Searle and the joint press release

$xxxxxxxx, and (iii) $xxxxxxxx, an additional payment of $xxxxxxxx. Payment
shall be made by Buyer within sixty (60) days after the end of the calendar
quarter in which each such Net Sales hurdle is achieved. For illustrative
purposes, if annual Net Sales of such Products in the aggregate exceed or any
such calendar year $45,000,000, the total payments for such calendar year would
be $xxxxxxxx.

         3.12 $xxxxxxxx, $xxxxxxxx and $xxxxxxxx, respectively, upon the
Technology Transfer of each of the Xxxxxxx Product, the Xxx-xxxxxxx Product and
the Xxxxxxx Product, respectively, to a Buyer designated facility ("Technology
Transfer Payments"). If the parties reasonably determine that the Xxxxxxx
Development Product shall not require said transfer (as a result of
manufacturing related development activities being transferred to a Buyer
designated facility), the Technology Transfer Payment for the XxxxxxxDevelopment
Product shall be paid at the same time as the Technology Transfer Payment for
the Xxx-xxxxxxx xxx Development Product. If Seller has made commercially
reasonable efforts to effect a Technology Transfer and the Technology Transfer
has not been accomplished at the end of the two year period from the
commencement of efforts (i.e., the delivery to Buyer of relevant Know-How
documentation) to effect said Technology Transfer, then (a) if the Technology
Transfer has not occurred solely due to regulatory issues, then the Technology
Transfer Payments shall be made upon the earlier of (i) completion of the
Technology Transfer, or (ii) six months after the aforementioned two year
period; or (b) if there are no regulatory issues then impeding said Technology
Transfer, then the Technology Transfer Payments shall be due and payable two

Know-How documentation) to effect said Technology Transfer. Notwithstanding the
foregoing, if Buyer does not acquire the Xxxxxxx Product pursuant to Section
3.10, then Buyer shall not be obligated for the Technology


                                       8
<PAGE>

Transfer Payment for the Xxxxxxx Product.

         3.13 For clarification purposes, Sections 3.5, 3.6, 3.7 and 3.8 refer
to "FDA approval to market the Xxxxxxx Product" which is intended to be distinct
and different from "FDA approval letter" referenced in Section 3.4. It is noted
the a FDA approval letter may contain conditions that must be satisfied prior to
launching a product, e.g., satisfactory pre-approval site inspection(s),
pre-shipment inspection(s).

         3.14 The parties will cooperate in the allocation of the purchase price
for the Assets for tax purposes in accordance with Internal Revenue Code (IRC)
Section 1060 and make every effort to allocate on a reasonable basis.

         3.15 BUYER acknowledges and accepts that any breach of this Section 3
will cause irreparable harm, and recovery of damages may not be adequate
compensation in light of Seller's obligations under Sections 2, 8.3 and 8.5.
Accordingly, except as provided in the following sentence, if Buyer fails to
make any of the payments required under Article 3 when such payments become due
and payable hereunder, (a) Seller shall have the right to (i) immediately cease
all of the technology transfer activities contemplated in Section 8.3, and (ii)
immediately cease all of the regulatory activities contemplated in Section 8.5,
and (iii) equitable relief, in addition to all other remedies available at law
or in equity, including injunction and specific performance, and (b) all Assets
relating to any Product(s) for which Buyer has failed to make such payments
shall immediately revert to Seller. Seller may exercise its rights hereunder
only after providing Buyer with written notice of such failure and Buyer has not
made such payments within fifteen (15) days following the date of such notice.

withheld) reasonably required to obtain such approval; provided, however, that
Buyer and Seller shall work together to create interim labeling (the "Interim
Labeling") that changes the NDC number for the Products and identifies Buyer as
the seller of the Products as expeditiously as possible. The intent of the
parties is that the Interim Labeling shall be a notification filing with the FDA

require FDA approval with respect to the Interim Labeling.

associated with any Product that accrues after Closing but prior to transfer of
such Registration. Notwithstanding anything contained elsewhere herein, Buyer
shall hold Seller and its Affiliates harmless from and against any fees,
penalties, fines, and third party claims due to Buyer's failure to record any
assignment of any such Registration pursuant to this Section, except if such
fee, penalty, fines, or third party claim is due to the conduct of Seller.

prior notice, make available to the other, to the extent reasonably required for
the purpose of assisting Seller or Buyer in obtaining governmental approvals and
preparation of tax returns relating to the Assets, and prosecuting or defending

delayed.

good faith efforts to obtain, and to cooperate with the others in obtaining, all

cooperate with making any filings required by the Securities and Exchange

Purchase Agreement prior to or after the Closing, and to take all reasonable
actions to avoid the entry of any order or decree by any governmental agency

ARTICLE 2 -- PROCESSING AND PACKAGING AND PRICE
2.1        UNDERTAKING.
           (a)      Subject to the limitations contained herein, SEARLE hereby
                    agrees to Process and Package or to have Processed and
                    Packaged BUYER's orders for the Products in the Territory
                    and BUYER agrees to pay SEARLE for the quantity of Products
                    so Processed and Packaged in accordance with this Agreement.
                    SEARLE shall not be obligated to Process and Package
                    Products in excess of the capacity limitations described in
                    Sections 3.1 and 3.2.
           (b)      For the duration of this Agreement, BUYER 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. (For the
                    avoidance of doubt, under the Asset Purchase Agreement,
                    SEARLE retained ownership of the Assets outside of the
                    Territory.)
           (c)      The parties acknowledge that any of SEARLE's obligations

                                       2
<PAGE>

                    hereunder may be carried out, at SEARLE's election, by third
                    party manufacturers; provided that SEARLE's use of any third
                    party manufacturer, other than a Syntex Facility
                    manufacturer, shall require BUYER's prior written consent,
                    which consent shall not be unreasonably withheld. The use of
                    any third party manufacturer shall not relieve SEARLE of its
                    obligations under this Agreement.
2.2        PRICE AND PAYMENT.
           (a)      During the Initial Term, the prices for Processing and
                    Packaging the Products shall be equal to the lesser of the
                    Cost of Manufacture or $xxxxxxxx per cycle determined under
                    a weighted average price computation for all products
                    purchased by Buyer; provided however the parties shall
                    negotiate a revised maximum price per cycle if the active
                    ingredient component of Cost of Manufacture increases by
                    more than five percent (5%). For purposes hereof, "weighted
                    average price" shall be determined by dividing the sum of
                    the Cost of Manufacture for a Batch of each of the Products
                    by the sum of the number of cycles in each such Batch. The
                    prices in effect for the remainder of calendar year 1997 and
                    an example of a "weighted average price" computation are set
                    forth in Schedule 2.2(a). Thereafter, the prices shall be
                    adjusted as provided in subsection (c) below.
           (b)      During any extended term following the Initial Term, the
                    prices for Processing and Packaging the Products shall be
                    equal to the Cost of Manufacture per cycle plus fifteen
                    percent (15%); provided, however, that the Cost of
                    Manufacture per cycle shall be commercially reasonable and
                    consistent with SEARLE's accounting practices for products
                    it manufactures in its facilities.
           (c)      By October 31st of each calendar year of the term hereof,
                    SEARLE

                    shall estimate the Cost of Manufacture for the following
                    calendar year and provide BUYER written notice thereof.
                    SEARLE's invoices shall state the estimated Cost of
                    Manufacture. Any differences between such estimated Cost of
                    Manufacture and the actual Cost of Manufacture during the
                    month in which Products covered by such invoices were
                    shipped shall be adjusted annually. Any such adjustment
                    shall be made by SEARLE not later than March 31 for the
                    prior calendar year. SEARLE shall endeavor, but shall not be
                    obligated, to provide notice to BUYER of potential
                    adjustments hereunder.
           (d)      The Products will be shipped to a location in the Territory
                    designated by BUYER, FCA (Incoterms 1990) SEARLE's
                    manufacturing plant. Title and risk of loss shall pass to
                    BUYER upon delivery of the Products to the common carrier.
           (e)      BUYER will pay in U.S. currency for each shipment of
                    Products within forty-five (45) days after the date the
                    relevant invoice is received by BUYER or the date of
                    shipment, whichever is later.
2.3        DEFINITION OF "COST OF MANUFACTURE". SEARLE's cost of manufacture for
           the Products (the "Cost of Manufacture") (as calculated in accordance
           with generally accepted accounting principles) shall be equal to the
           sum of:
          (a) Costs of any third party manufacturers, utilities, materials,
              indirect materials and supplies used in the Processing and
              Packaging of Products;
          (b) Wages of those employees directly employed in the Processing and
              Packaging of the Products;
          (c) Wages of employees  directly employed in quality control,
              materials management or related functions which are applicable to
              the Processing and Packaging of Products and the salaries of the
              supervisors of said functions (or an appropriate  portion of such
              wages

                                       4
<PAGE>

              and salaries if such personnel are not employed exclusively
              in said manufacture);
          (d) That portion of payroll taxes, benefits, social security payments,
              vacation and bonus payments and other employee costs allocable to
              the wages and salaries included within the provisions of
              subparagraphs (b) and (c) above; and
          (e) That portion of SEARLE's manufacturing overhead expenses, based
              on the manufacturing facility operating at full capacity during
              normal business hours (one 8-hour shift), apportioned, in
              accordance with generally accepted accounting principles and
              SEARLE's current practices, to the manufacture of the Products
              supplied to BUYER.
2.4        RECORDS OF SEARLE. SEARLE shall keep records of its Cost of
           Manufacture in accordance with generally accepted accounting
           principles in the United States. Such records shall be maintained by
           SEARLE for a period of two (2) years. 
2.5        AUDIT. Not more frequently than once each year, BUYER at its expense
           through an independent auditor of its choice to whom SEARLE has no
           reasonable objection and subject to the provisions of Section 2.7,
           shall have the right to conduct an examination or audit of said
           records of SEARLE in order to verify that amounts paid to SEARLE
           hereunder are correct. SEARLE agrees to cooperate fully with the
           auditor and to provide all reasonable access to records and employees
           necessary to promptly complete this audit. BUYER, at BUYER's expense
           and reimbursement of any costs to SEARLE, may elect to have an audit
           conducted with respect to a Syntex Facility pursuant to such rights
           and conditions as SEARLE may have with respect to audits of such
           Syntex Facility.
2.6        ADJUSTMENTS. In the event any examination or audit of the records of
           SEARLE discloses an under- or overpayment hereunder, written notice
           of such fact, specifying the amount and basis of the under- or
           overpayment

                                       5
<PAGE>
           shall promptly be furnished to both parties by the person(s)
           performing the examination or audit. In the event of an overpayment
           the amount thereof shall be credited against future amounts owed to
           SEARLE hereunder, or if there will be no such future amounts, SEARLE
           shall refund the overpayment to BUYER within thirty (30) days of such
           notice. In the event of an underpayment, BUYER shall pay the amount
           thereof to SEARLE within thirty (30) days after such disclosure.
2.7        SCOPE OF EXAMINATION AND AUDIT. The examination and audit provided
           for in Section 2.5 shall be restricted to those records of SEARLE
           which relate to the services provided hereunder and costs and
           expenses incurred hereunder, and shall be undertaken for the sole
           purpose of verifying information provided by SEARLE and payments made
           to SEARLE hereunder. The independent auditor shall not disclose to
           BUYER any information obtained in the course of its audit other than
           information relating solely to the accuracy of the statements
           provided by SEARLE and payments to be made to SEARLE pursuant to this
           Agreement. BUYER, its representatives and any independent auditor
           appointed by it shall keep all information obtained in the course of
           any examination or audit confidential, except to the extent
           disclosure of under- or overpayment is contemplated herein. If the
           auditor determines that SEARLE has overcharged the BUYER by five per
           cent (5%) or more for the Products purchased by the BUYER for the
           period audited, SEARLE agrees to promptly reimburse the BUYER for all
           costs and expenses incurred by BUYER in having said audit conducted.

ARTICLE 3 -- FORECASTS AND ORDERS
3.1        FORECASTS
           (a)      At least thirty (30) days prior to each calendar quarter,
                    BUYER will provide SEARLE with a written twelve (12) month
                    rolling forecast of the quantities of each Product that
                    BUYER expects to purchase during each of the next twelve
                    (12) months (the Twelve Month Forecast"); provided, however,
                    the first Twelve Month Forecast shall be attached hereto as
                    Schedule 3.1(a)-I. 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 one-hundred thirty
                    percent (130%) of the forecast for the prior Contract Year.
                    For purposes of bench-marking the current forecast for the
                    prior Contract Year to which BUYER will be limited under
                    this Section 3.1(a), attached as Schedule 3.1(a)-II is the
                    most recent Contract Year forecast submitted by SEARLE to
                    its third party manufacturer.
           (b)      The first three (3) months of each Twelve Month Forecast
                    (the "Three Month Forecast") shall be firm and shall not
                    have been changed from the  forecasted  amounts for the same
                    calendar months contained in the prior Twelve Month
                    Forecast.
3.2        PERMITTED AMOUNT TO BE ORDERED. BUYER shall submit a purchase order
           to SEARLE referencing this Agreement each month as required, with a
           delivery date of, except as otherwise provided in this Section 3.2,
           not less than ninety (90) days after the date thereof. The quantities
           ordered will be no less than eighty percent (80%) of the Three Month
           Forecast for such month and no more than the greater of one hundred
           twenty percent (120%) of the Three Month Forecast for such month or
           an additional Batch, provided raw materials are available for the
           amounts over one hundred percent (100%) of the Three Month Forecast.
           SEARLE will use its reasonable efforts, but will be under no
           obligation, to supply Product in


                                       7
<PAGE>

           excess of one hundred twenty percent (120%) of the Three Month
           Forecast. With respect to the inventory identified on Schedule 3.2,
           BUYER may submit purchase orders with a delivery date of not less
           than seven (7) days after the date thereof. Products, when delivered
           to the common carrier under subsection 2.2(d), shall not have an
           expiration date of less than eighteen (18) months from the date of
           such delivery, except (a) for Products purchased from the inventory
           set forth on Schedule 3.2, (b) for the bridging inventory described
           under Section 3.4, and/or (c) as the parties may agree otherwise in
           writing on a case by case basis. With respect to subsection (c),
           SEARLE shall notify BUYER in writing when and if it has Products
           which have an expiration date of less than eighteen (18) months (but
           in no event less than fifteen (15) months) and BUYER shall notify
           SEARLE within three (3) days of receipt of such notice whether it
           wishes to accept such Products. In the event BUYER accepts such
           short-dated Products and BUYER's customer(s) later return such
           Products solely as a result of their being short-dated, then SEARLE
           shall reimburse BUYER for the actual amount refunded or credited to
           BUYER's customer(s) for such returned Products and the reasonable
           expenses related to processing such returned Products. The
           record-keeping and audit provisions of Sections 2.4, 2.5, 2.6 and 2.7
           shall apply mutatis mutandis to SEARLE's right to audit BUYER's
           Product returns records pursuant to Section 2.2.
3.3        MINIMUM ORDER SIZE. The minimum size of any order for any Product
           shall be one Batch of such Product with larger orders being in whole
           number multiples of a Batch. BUYER's forecasts and orders for
           finished Product under this Article 3 may be allocated among such
           Product cycles referenced on Schedule 1.8 as BUYER may desire,
           subject to the minimum Batch sizes set forth in this Section 3.3.
3.4        BRIDGE  INVENTORY. Prior to the expiration of the Initial Term or
           extended term, as the case may be, SEARLE shall use reasonable
           efforts to assist

                                       8
<PAGE>

           BUYER in obtaining a stock pile of inventory of the applicable
           Products to the extent such stock pile is necessary in order to
           bridge the period beginning with such expiration and the commencement
           of BUYER's manufacture thereof. BUYER shall be responsible for
           providing sufficient notice to SEARLE of the amount of inventory so
           required by BUYER within the usual capacity limitations of SEARLE's
           facility and/or a Syntex Facility.
3.5        FAILURE TO SUPPLY.
           (a)      In the event SEARLE fails or is unable to supply the
                    quantities of the Products ordered by BUYER to meet BUYER's
                    requirements (within the limits described in Section 2.1
                    above), BUYER may (i) purchase or obtain so much as to meet
                    its requirements or any portion thereof from any other
                    source or (ii) to the extent permitted by law manufacture
                    the same under the applicable Specifications and quality
                    control procedures. In such event, SEARLE shall provide
                    BUYER or BUYER's contract manufacturer with all documents,
                    data and other information necessary or useful for
                    Processing and Packaging the Products at no cost for so long
                    as SEARLE is unable to supply sufficient quantities of the
                    Products to meet BUYER's requirements.

4.2        BUYER'S CHANGES. The Specifications may be changed by BUYER,
           provided 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
           twice per year unless required by the FDA or other U.S. 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 obsolescence of any materials specifically purchased by
           SEARLE for Processing and Packaging of the Products under this
           Agreement prior to being notified in writing by BUYER of the change
           in the Specifications, BUYER shall reimburse SEARLE for the actual
           out-of-pocket cost of all such materials except to the extent the
           quantity of such materials exceeds requirements therefor pursuant to
           BUYER's forecasts. Upon being reimbursed and at BUYER's request,
           SEARLE shall promptly ship any such materials to a location
           designated by BUYER at BUYER's expense. If any such change or
           proposed change to the Specifications results in costs and expenses
           to SEARLE, BUYER shall promptly reimburse all such reasonable costs
           and expenses to the extent that such costs and expenses are not
           included in SEARLE's revised Cost of Manufacture and recovered within
           twelve (12) months of implementation of the change.
4.3        SEARLE CHANGES. SEARLE may change the Specifications at any time upon
           sixty (60) days prior written notice to BUYER, provided the
           Specifications at all times shall be in compliance with the Product
           Registrations. Any changes to Specifications under this Section 4.3
           shall be subject to BUYER's reasonable objections thereto, provided
           that any objections to such changes shall be delivered in writing to
           SEARLE within fifteen (15) days of BUYER's receipt of notice of such
           changes.

           in the event of a significant increase in the number of complaints
           received by SEARLE as compared to prior periods. SEARLE shall provide
           BUYER with a copy of SEARLE's annual adverse drug experience report

           Product complaints activities for such party and coordinate such
           activities with the other party. However, SEARLE's handling of

           health risk SEARLE may conduct a recall of the Product upon notice to

           (b)      the Products, when delivered to the common carrier under
                    subsection 2.2(d), shall neither be adulterated or
                    misbranded within the meaning of the United States Food,
                    Drug and Cosmetic Act, 21 U.S.C. "301c et. seq.; and
           (c)      EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN THIS AGREEMENT,
                    SEARLE MAKES NO REPRESENTATIONS AND EXTENDS NO WARRANTIES OF
                    ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING ANY EXPRESS
                    OR IMPLIED WARRANTIES OR MERCHANTABILITY OR FITNESS FOR A
                    PARTICULAR PURPOSE.
7.2        BUYER WARRANTIES. BUYER warrants that:
           (a)      to the extent that it provides any materials or engages in
                    Processing or Packaging with respect to the Products, all
                    such materials, Processing and Packaging will comply with
                    the Specifications and with all applicable laws, rules,
                    orders and regulations, including GMPs; and

           (b)      subject to SEARLE's compliance with the warranties stated in
                    Section 7.1 above, the Products which BUYER distributes and
                    sells will not be adulterated or misbranded within the

7.3        INSPECTION. SEARLE agrees to permit BUYER's designated
           representatives to whom SEARLE has no reasonable objection to inspect
           SEARLE facilities at which the Products are Processed, Packaged,
           stored or tested for the purpose of determining compliance with
           applicable regulations and the Specifications at reasonable times

           each shipment, BUYER 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 BUYER to reasonably believe that any shipment
           or part thereof fails, to conform to the Specifications or shall have
           been Processed, Packaged or shipped under conditions which do not
           comply with the FDA requirements or the provisions of this Agreement,
           BUYER may reject the same by giving prompt written notice to SEARLE
           specifying the manner in which it fails to meet the requirements
           hereof. SEARLE shall have thirty (30) days within which to accept or
           reject BUYER's claims. BUYER may withhold payment for any shipment of
           Products that fails to meet the requirements hereof.
7.5        DISPUTES. In the event of any dispute as to whether any shipment of
           Products fails in whole or part to meet the Specifications, such
           dispute shall be promptly resolved by an independent testing
           organization of recognized repute within the U.S. pharmaceutical
           industry mutually agreed upon by the parties, the appointment of
           which shall not be unreasonably withheld by either party. Until any
           dispute is resolved, BUYER will not dispose of

           such party by a third party (i) as a result of BUYER's use,
           promotion, sale and/or distribution of the Products unless such
           liability arises from SEARLE's breach of any warranty or
           representation herein, SEARLE's failure to perform any covenant
           herein, or the negligent act or omission of SEARLE in performing its
           obligations under this Agreement or (ii) arising from the failure of
           BUYER to conduct a recall of any of the Products requested by SEARLE.

           attorneys' fees) arising from or related to any claim, action or
           proceeding made or brought against such party by a third party as a
           result of SEARLE's breach of any warranty or representation herein,
           SEARLE's failure to perform any covenant herein, or the negligent act
           or omission of SEARLE in performing its obligations under this
           Agreement.
8.3        NOTICE; DEFENSE. In the event of any claim, action or proceeding for

           assume responsibility for and shall have full control of the defense
           of such matter and Claimant shall fully cooperate in Indemnitor's

<PAGE>

           defense within the aforementioned time period, shall constitute a
           waiver of the Indemnitor's rights to assume the defense and 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 compromise claims

           might otherwise be to the contrary, except as expressly set forth in

12.5       ENTIRE AGREEMENT. This Agreement, together with any Schedules hereto
           and the Asset Purchase Agreement, constitutes 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.
12.6       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. BUYER and SEARLE may
           each assign all 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, SEARLE may assign
           all of its rights and obligations hereunder to a purchaser of all or
           substantially all of the assets or business of SEARLE.
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 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, then such party shall be
           excused from 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 or a third party manufacturer
           designated by SEARLE under Section 2.1(c).
12.12      PUBLICITY. Neither SEARLE nor BUYER, 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.
