 with WARNER-LAMBERT, to promote and detail Products in the Co-Promotion
 Territory pursuant to the terms of this Agreement.  Subject to the
 provisions of Section 2.02(d), so long as PFIZER's rights of co-promotion

 grant any rights to, or permit or authorize any third party (other than a

 wholesalers and other third parties in the chain of distribution), or to
 promote or detail Products in the Co-Promotion Territory in a manner
 similar to the detailing and promotion of Products by PFIZER pursuant to
 this Agreement.

      SECTION 2.02.  Detailing and Promotional Efforts.

      (a)  Both PFIZER and WARNER-LAMBERT shall deploy such of their
 respective sales forces in an effort to promote effectively and detail the
 Products in the Co-Promotion Territory in accordance with the terms of this
 Agreement and the relevant Marketing Plan.  In conducting such promotion
 and detailing both PFIZER and WARNER-LAMBERT shall use reasonable
 commercial efforts consistent with accepted pharmaceutical industry
 business practices.  No party shall be required to undertake any activity
 under this Agreement which it believes, in good faith, may violate any Laws
 or codes of practice.

      (b)  Each party shall diligently work to fulfill all responsibilities
 assigned to it under this Agreement and each Marketing Plan and shall
 comply with all applicable Laws in the Co-Promotion Territory.  It is the
 intention of the parties that during each Agreement Year with respect to
 each Category 1 Country each of WARNER-LAMBERT and PFIZER will devote
 substantially equal efforts and internal resources to the marketing,
 promotion and detailing of the Products and the other activities
 contemplated under this Agreement; provided, however, (i) with respect to
 each Category 2 Country such efforts and resources shall be 33% for PFIZER
 and 67% for WARNER-LAMBERT and (ii) with respect to each Category 3 Country
 such efforts and resources shall be 67% for PFIZER and 33% for WARNER-
 LAMBERT.  The Marketing Plans developed under Section 4.01 shall reflect
 the foregoing.  If the parties agree that additional detailing or other
 internal resources are necessary beyond those contemplated in this
 Agreement, or if one party is requested to devote its resources in excess
 of its appropriate share, the parties shall first determine fair
 compensation to such party for its additional efforts.  Furthermore, no
 party hereto shall be required, without its consent, to devote any
 employees or other internal resources of a type, scope or nature which are
 materially different from those provided by the other party.

      (c)  During each Agreement Year in each Category 1 Country, each of
 PFIZER and WARNER-LAMBERT shall be responsible for performing a number of
 Details equal to fifty percent (50%) of the Details designated for such

 with respect to each Category 2 Country PFIZER shall be responsible for
 performing a number of Details equal to 33% of the Details called for in
 the Marketing Plan then in effect for such Agreement Year, and WARNER-
 LAMBERT shall be responsible for performing 67% of the Details called for
 in such Marketing Plan and (ii) with respect to each Category 3 Country
 PFIZER shall be responsible for performing a number of Details equal to 67%
 of the Details called for in the Marketing Plan then in effect for such
 Agreement Year, and WARNER-LAMBERT shall be responsible for performing 33%
 of the Details called for in such Marketing Plan.

      (d)  Upon written notice to the other party, WARNER-LAMBERT and PFIZER
 shall each have the right to use the services of a contract sales force
 (i.e. a third party whose primary business is devoted to detailing third
 party products) to assist such party in satisfying its obligations
 hereunder; provided, however, that during Agreement Years One and Two in
 each Country, PFIZER and WARNER-LAMBERT will promote the Product solely
 through their respective existing experienced sales forces and will not
 rely upon contract sales forces (other than the United Kingdom, where
 PFIZER shall have the right during Agreement Years One and Two to
 supplement its existing sales force with contract sales forces in a manner
 consistent with its past practices); provided, further, that after such
 time as WARNER-LAMBERT terminates PFIZER's co-promotion rights under
 Sections 14.02(a) or 14.02(b), in no event shall WARNER-LAMBERT be
 permitted to use in any Country a contract sales force (without PFIZER's
 prior consent) to perform a number of Details greater than such number of
 Details performed in such Country by a contract sales force for WARNER-
 LAMBERT prior to such termination of PFIZER's co-promotion rights.
 Furthermore, in no event shall WARNER-LAMBERT increase in any Country its
 use of such a contract sales force (without PFIZER's prior consent) to
 perform a greater number of Details in anticipation of its decision to
 terminate PFIZER's co-promotion rights in such Country pursuant to Sections
 14.02(a) or 14.02(b).

      SECTION 2.03.  Detailing Reports.  Each party shall provide to the
 other party a report of the number of Details carried out by its
 representatives during each Agreement Quarter.  Reports shall be delivered
 to the other party within six weeks of the end of the applicable Agreement
 Quarter.

      (a)  WARNER-LAMBERT shall exercise reasonable efforts to obtain, as
 soon as reasonably practicable, the Marketing Authorization, and, where
 relevant, Price Approval, for a Product with a package insert or, in the
 case of Canada, a Product monograph, that is materially equivalent to the
 provisions of Exhibit C.

      (b)  WARNER-LAMBERT shall be entitled at any time to cease permanently
 the sale of any Product in any Country if continued sale of such Product
 would be in violation of Laws or if WARNER-LAMBERT in good faith believes
 that it has an ethically valid reason therefor based on medical or
 scientific problems concerning such Product.

      (c)  Except as otherwise provided in Sections 3.01 and 3.02 of the
 International Collaboration Agreement, WARNER-LAMBERT shall be under no
 liability whatsoever to compensate PFIZER or make any other payment to
 PFIZER if (i) Marketing Authorization or Price Approval is not received,
 (ii) the approved package insert or, in the case of Canada, the Product
 monograph for the first Product is not materially equivalent to the
 provisions of Exhibit C, or (iii) if WARNER-LAMBERT determines to take any
 of the steps that it is permitted to take pursuant to this Section 2.04,
 provided, in the case of (i), (ii) and (iii) above, such failure to obtain
 such Marketing Authorization or Price Approval or, in the case of (b)
 above, such cessation of sale shall not be the result of any breach of this
 Agreement by WARNER-LAMBERT.

 selected by WARNER-LAMBERT in its sole discretion and owned by WARNER-
 LAMBERT or by any of its Affiliates (the "Trademark").  PFIZER shall have
 no rights under this Agreement in or to the Trademark or the goodwill
 pertaining thereto except as specifically provided herein.  PFIZER shall
 utilize the Trademark only for the purposes contemplated herein.  PFIZER
 agrees that upon termination or expiration of this Agreement (or upon
 PFIZER no longer retaining co-promotion rights under Section 2.01 if such
 date occurs first), it will discontinue forthwith all use of the Trademark.

      (b)  Except as specifically set forth in this Agreement, PFIZER shall
 not enjoy or exercise any proprietary or property right or other interest
 in the Trademark, the Patents or in any copyright owned by WARNER-LAMBERT
 or any of its Affiliates and relating to any Product.

      (c)  PFIZER is the owner of the PFIZER logo set forth on Exhibit D
 (the "PFIZER Logo").  PFIZER grants WARNER-LAMBERT the right to use the
 PFIZER Logo on labeling, package inserts, Product monographs and packaging
 materials for Products, all Promotional Materials (as hereinafter defined),
 Samples (as hereinafter defined) and any other materials used in connection
 with the performance of this Agreement during the Term of this Agreement
 (or the period of time in which PFIZER retains co-promotion rights under
 Section 2.01 if shorter) and for the period of six (6) months thereafter
 for all Products, Promotional Materials, Samples, labeling, inserts and
 Product monographs containing the PFIZER Logo; provided, however, such use
 shall be consistent with the uses approved by PFIZER's representatives on
 the Operating Committee (or the applicable Country Marketing Team).
 WARNER-LAMBERT shall have no rights under this Agreement in or to the
 PFIZER Logo or the goodwill pertaining thereto except as specifically
 provided for herein.  Except as provided for in this Section 2.05(c),
 WARNER-LAMBERT agrees that upon termination or expiration of this Agreement
 (or upon PFIZER no longer retaining co-promotion rights under Section 2.01
 if such date occurs first), it will discontinue forthwith all use of the
 PFIZER Logo.

      SECTION 2.06.  Non-Compete.  During the Term of this Agreement and for
 two (2) years thereafter, neither PFIZER nor WARNER-LAMBERT (nor their
 respective Affiliates or licensees) shall, directly or indirectly, market,
 sell, detail, promote or distribute any Competing Products in any part of
 the Co-Promotion Territory.

 3.02(b), 3.02(c) or 3.02(d), as the case may be, for such Agreement Year;
 provided that if the amount paid to PFIZER for the first three Agreement

 PFIZER's notice under Section 3.03(b), notify PFIZER of the calculation of
 the total amount of Product Expenses for such Agreement Quarter by Country,
 the amounts paid or accrued by each of WARNER-LAMBERT or PFIZER, and the
 amounts, if any, payable by either party to the other in accordance with
 Sections 3.01(b), 3.02(a) and 3.03(a).

      (d)  Provided PFIZER has complied with Section 3.03(b), WARNER-LAMBERT

 under Sections 3.03(c) and 3.03(d) shall be offset against any amounts due
 such party and the net amount shall be paid by WARNER-LAMBERT or PFIZER, as
 the case may be, within ten (10) business days after notification by
 WARNER-LAMBERT pursuant to Section 3.03(c) or Section 3.03(d).

      (f)  For the period of time from April 15, 1996 to the expiration of

                 ARTICLE IV - COOPERATION; MARKETING PLANS;
                         CLINICAL DEVELOPMENT PLANS

      SECTION 4.01.  Cooperation.

      (a)  Subject to the other provisions of this Agreement, the parties
 agree that the principal objectives of the parties hereunder in jointly
 promoting and detailing Products in the Co-Promotion Territory are to use
 reasonable efforts to maximize Net Sales and operating income to the
 parties hereunder and to develop and sponsor various local clinical studies
 for the Product during the period of time WARNER-LAMBERT and PFIZER shall
 be co-promoting the Products under this Agreement.  The parties agree that
 they shall establish a formal framework within which they will discuss
 strategies for the development, marketing and detailing of the Products in
 the Co-Promotion Territory.

      (b)  The formal framework referred to in Section 4.01(a) shall
 initially be comprised of the following:

      (i)  An Operating Committee, which shall operate by consensus between
           the parties, shall meet at least quarterly and shall have as its
           overall purpose the development and implementation of commercial
           planning activities and research and development programs, each
           consistent with the other. The Operating Committee shall have
           subcommittees as set forth below.  The Operating Committee shall
           consist of an equal number of representatives of each party,
           chaired by a senior sales and marketing manager of WARNER-
           LAMBERT, shall review the activities of the U.S. Marketing
           Subcommittee (established under the U.S. Agreement), the Global
           Business Subcommittee, the Research Subcommittee (established
           under the U.S. Agreement) and any other subcommittees formed from
           time to time, and seek to resolve any matter upon which any such
           subcommittee is unable to agree.

      (ii) A Global Business Subcommittee, which shall operate by consensus
           between the parties, comprising an equal number of
           representatives of each party, chaired by a senior marketing
           manager of WARNER-LAMBERT, which shall meet at least quarterly
           to:  (a) develop and discuss global strategies for marketing of
           the Product, including allocation of responsibility for global
           marketing activities, (b) develop and review global marketing
           plans (including the budget for advertising, promotional
           strategies) and Clinical Plans, (c) review progress against the
           current global marketing plans, (d) review progress of marketing
           expenditures in each Agreement Year against the budget for such
           activities in such  Agreement Year, (e) review potential
           amendments to the current global marketing plans (including the
           budget for advertising and promotional strategies), (f) make
           presentations to the Executive Committee and (g) undertake all
           other responsibilities deemed necessary in connection with the
           management of the promotion and marketing of the Product in the
           Co-Promotion Territory.  The Global Business Subcommittee also
           shall have responsibility for reviewing the operating plans of
           all Countries in the Territory (as such term is defined in the
           International License Agreement) other than those countries in
           which WARNER-LAMBERT or its Affiliates sell a Product.

     (iii) A Country Marketing Team for each Country which shall
           operate by consensus between the parties to accomplish the
           objectives and intent of Sections 4.01(a) and (c) through
           (f) for each such Country, comprising an equal number of
           representatives of each party.

      (iv) An Executive Committee, which shall operate by consensus between
           the parties, comprising an equal number of senior executives of
           each party, chaired by a senior executive of WARNER-LAMBERT,
           which shall review the activities of the Operating Committee,
           including the Global Business Subcommittee thereof and the
           Research Subcommittee, and seek to resolve any matter upon which
           any such committee or subcommittee is unable to agree.

      (c)  The parties may, upon mutual agreement, supplement or vary the
 formal framework specified in Section 4.01(b) from time to time.

      (d)  If for any reason the Executive Committee cannot reach agreement
 on any appropriate matter, the matter shall be referred to the Chief
 Executive Officers of each party for good faith resolution. It is, however,
 expressly agreed that the WARNER-LAMBERT Chief Executive Officer, after
 consultation with the PFIZER Chief Executive Officer, shall have the final
 decision making authority with respect to the matters appropriately
 referred to him and such decision shall be binding on the parties, subject
 to the provisions of this Agreement.  Pursuant to the foregoing, it is
 acknowledged that the Chief Executive Officers of WARNER-LAMBERT and PFIZER
 may reasonably disagree on matters relating to strategies to market, detail
 and/or promote the Products in the Co-Promotion Territory.  The decisions
 of the WARNER-LAMBERT Chief Executive Officer on such matters shall be
 binding on the parties, provided such decisions are made in good faith and
 have a reasonable basis therefor.  In particular, it is agreed that such
 decisions cannot be challenged on the basis of being inconsistent with the
 first two sentences of Section 2.02(a) or the first sentence of Section
 4.01(a), provided such decision shall not be in conflict with other
 specific provisions of this Agreement.

      (e)  Each Country Marketing Team shall seek to produce a pre-launch
 activities plan and a draft Marketing Plan for Agreement Year One by or
 before December 31, 1996.  At least six months prior to anticipated
 approval of a Marketing Authorization the Country Marketing Team shall
 finalize the Marketing Plan for Agreement Year One and for each ensuing
 Agreement Year on or before October 31 of the prior Agreement Year or such
 other date as may be determined in accordance with this Section 4.01;
 provided, however, that the Country Marketing Team for each of Germany and
 the United Kingdom shall seek to produce a Marketing Plan for Agreement
 Year One by or before October 31, 1996.  Each Country Marketing Team shall
 also produce a Clinical Plan.

      (f)  Subject to the provisions of this Agreement, each Marketing Plan
 shall stipulate the way in which the Products are to be promoted and
 detailed during the period to which the Marketing Plan relates and shall
 include, inter alia: (i) the number, type and priority of Details to be
 performed and strategies relating to such detailing activity, (ii) other
 advertising and promotional activity to be undertaken, (iii) any training
 and/or sampling programs to be conducted, (iv) budgets, (v) medical
 education programs to be conducted, (vi) public relations activities and
 (vii) such other activities as may be agreed on by the Global Business
 Subcommittee, the applicable Country Marketing Team, the Operating
 Committee, the Executive Committee or determined or varied pursuant to the
 provisions of Section 4.01(d).  The Marketing Plans shall not address sales
 force incentives or compensation, and each party shall have sole authority
 and responsibility for designing and executing any such program for its
 sales force.  Neither party shall make any material change in any Marketing
 Plan or Clinical Plan without the prior approval of the Global Business
 Subcommittee.

      (g)  All of the committees and subcommittees contemplated hereunder
 shall be established as soon as reasonably practicable after the date of
 this Agreement. Each party shall bear its own costs associated with its
 participation on the various committees and subcommittees.

      SECTION 4.02.  Information Exchange.  Each party shall forthwith upon
 the execution of this Agreement and thereafter at all times during the
 Agreement Years promptly disclose to the other party all significant
 information of which it becomes aware, which it can legally disclose and
 which it reasonably believes will be important in planning and effecting
 the detailing, promotion, marketing and sale of the Products in the Co-
 Promotion Territory.

 modifications of such programs each may develop in the future which are not
 specific to the Products.  PFIZER and WARNER-LAMBERT shall, from time to
 time, each notify the other as to the identity of such proprietary
 programs.  In the event that WARNER-LAMBERT desires after the expiration or
 termination of this Agreement, to use any PFIZER program which has been
 specifically adapted for, or directed to, any of the Products, the parties
 shall negotiate in good faith to conclude, if possible, an appropriate
 agreement (including the amount of compensation to be paid to PFIZER for
 such use).  In addition, all such new programs hereafter jointly developed
 by PFIZER and WARNER-LAMBERT pursuant to this Agreement shall be jointly
 owned by PFIZER and WARNER-LAMBERT, and each party shall have the right to
 use such jointly developed programs free of charge after the Term of this
 Agreement.

      (c)  PFIZER shall not produce (other than as concepts for
 consideration by WARNER-LAMBERT), distribute or otherwise use any
 promotional or communications material relating to the Products which has
 not been approved in accordance with the management framework established
 in Section 4.01 and by WARNER-LAMBERT pursuant to Section 5.01(a).

      (d)  Each party shall during each Agreement Year provide the other
 party with such quantities of Promotional Materials consistent with the
 applicable Marketing Plan and the provisions of this Agreement to meet such
 party's reasonable requirements for use in accordance with the then current
 Marketing Plan.

      SECTION 5.02.  Samples.

      (a)  WARNER-LAMBERT shall during each Agreement Year provide PFIZER
 with such quantities of samples of the Products ("Samples") consistent with
 the applicable Marketing Plan and the provisions of this Agreement to meet
 PFIZER's reasonable requirements for use in accordance with the then

 accordance with the then current Marketing Plan and shall distribute
 Samples in full compliance with all applicable Laws.

      (b)  The cost per Sample distributed in each Agreement Quarter shall
 be calculated as twelve percent (12%) of the quotient of (i) Net Sales in
 such Agreement Quarter over (ii) the total number of pills of Product sold
 to unaffiliated third parties in each Country in such Agreement Quarter.

      (c)  Within thirty (30) days after the end of the Term of this
 Agreement (or, if earlier, the termination of PFIZER's co-promotion
 rights), PFIZER shall return, or otherwise dispose of in accordance with
 instructions from WARNER-LAMBERT, all remaining Samples provided by WARNER-
 LAMBERT and will provide WARNER-LAMBERT with a certified statement that all
 remaining Samples have been returned or otherwise properly disposed of and
 that PFIZER is no longer in possession or control of any such Samples in
 any form or fashion.

      SECTION 5.03.  Labeling.  The parties agree that, subject to the
 requirements of applicable Law, WARNER-LAMBERT and PFIZER shall be given
 equal exposure and prominence on all Product package inserts, Product
 monographs, packaging, Samples and all Promotional Materials used or
 distributed in the Co-Promotion Territory in connection with the Products
 under this Agreement; provided such equal exposure shall not be required
 where PFIZER has prohibited the use of the PFIZER Logo in accordance with
 the terms of Section 2.05(c).

               ARTICLE VI - INFORMATION CONCERNING THE PRODUCT

      SECTION 6.01.  Public Statements. PFIZER and WARNER-LAMBERT shall
 ensure that no claims or representations in respect of the Products or

 shall keep PFIZER informed of any such actions, provided any such revisions
 are not inconsistent with the decisions of the parties as determined in
 accordance with Section 4.01.  Within twenty (20) days after submission to
 the applicable Governmental or Regulatory Authority, WARNER-LAMBERT shall
 provide PFIZER with copies of all final submissions that are intended to

 any Law applicable to Atorvastatin or any Product, including, but not
 limited to, WARNER-LAMBERT meeting its reporting and other obligations to
 (i) maintain and update any Marketing Authorizations for the Products and

 assistance and actions shall include, among other things, keeping the other
 party informed, commencing within forty-eight hours of notification of any

 or indirectly) from, any Governmental or Regulatory Authority, which (a)
 raises any material concerns regarding the safety or efficacy of any
 Product, (b) which indicates or suggests a potential material liability for
 either party to third parties arising in connection with any Product, or
 (c) which is reasonably likely to lead to a recall or market withdrawal of
 any Product, provided that neither party shall be obliged to disclose
 information in breach of any contractual restriction which it could not
 reasonably have avoided.  For purposes of this Section 8.05, each of the
 events set forth in (a), (b) and (c) of this Section 8.05 shall be defined

           occurring in any post-marketing study conducted, sponsored or
           monitored by PFIZER or WARNER-LAMBERT) within ninety-six hours of
           the time such Serious Adverse Drug Experience Report becomes
           known to PFIZER or any of its Affiliates or any employee or agent
           of PFIZER or any of its Affiliates (the "PFIZER Group"); and

      (ii) notify WARNER-LAMBERT of all Adverse Drug Experience Reports

           Experience Report becomes known to any member of the PFIZER
           Group; and

     (iii) notwithstanding any other provision of this Section 8.06, use its

           21 C.F.R 312.32, within twenty-four (but, in no event, later than
           thirty-six) hours of the time any such experience becomes known
           to any member of the PFIZER Group; and

      (iv) notwithstanding any other provision in this Section 8.06, notify
           WARNER-LAMBERT of all other serious and unexpected adverse
           experiences occurring in connection with an IND study conducted,
           sponsored or monitored by PFIZER, as defined in 21 C.F.R 312.32,
           within seventy-two hours of the time any such experience becomes
           known to any member of the PFIZER Group.

      (b)  PFIZER shall notify WARNER-LAMBERT of all Adverse Drug Experience
 Reports occurring in any post-marketing study conducted, sponsored or
 monitored by PFIZER when such study is completed in a study report issued
 to WARNER-LAMBERT in connection therewith.  Each such final study report
 shall be provided to WARNER-LAMBERT within fifteen days of its completion.
 Except for Adverse Drug Experience Reports occurring in any post-marketing
 study conducted, sponsored or monitored by PFIZER, notification under this
 Section 8.06 shall be by facsimile and overnight courier and in accordance
 with instructions to be mutually agreed upon by PFIZER and WARNER-LAMBERT.
 All follow-up investigations concerning Adverse Drug Experience Reports and
 Serious Adverse Drug Experience Reports occurring during post-marketing
 studies shall be conducted by the party initiating, sponsoring or
 monitoring such study; provided that the results of such follow-up
 investigations conducted by PFIZER shall be delivered to WARNER-LAMBERT
 within ninety-six hours of the time such follow-up information is obtained
 by any member of the PFIZER Group.  All other follow-up investigations
 concerning Adverse Drug Experience Reports and Serious Adverse Drug
 Experience Reports shall be conducted by WARNER-LAMBERT.  PFIZER shall
 provide all reasonable cooperation with any investigation of any such
 spontaneous Adverse Drug Experience Report or Serious Adverse Drug
 Experience Report conducted by WARNER-LAMBERT.

      (c)  Subject to Section 8.01, (i) PFIZER shall not disclose any
 information concerning Adverse Drug Experience Reports or Serious Adverse
 Drug Experience Reports to any Person or Governmental or Regulatory
 Authority without the prior consent of WARNER-LAMBERT, and (ii) WARNER-
 LAMBERT shall have the sole discretion to determine whether any complaint,
 Adverse Drug Experience Report or Serious Adverse Drug Experience Report
 must be reported to the FDA or any other Governmental or Regulatory
 Authority.

      SECTION 8.07.  Recalls Or Other Corrective Action.  WARNER-LAMBERT
 shall have sole responsibility for and shall make all decisions with
 respect to any recall, market withdrawals or any other corrective action
 related to the Products.  WARNER-LAMBERT shall promptly notify PFIZER of
 any such actions taken by WARNER-LAMBERT which are reasonably likely to
 result in a material adverse effect on the marketability of any Product in
 any Country.  At WARNER-LAMBERT's request, PFIZER shall provide reasonable
 assistance to WARNER-LAMBERT in conducting such recall, market withdrawal
 or other corrective action and any documented, direct, out-of-pocket costs
 incurred by PFIZER with respect to participating in such recall, market
 withdrawal or other corrective action shall be reimbursed by WARNER-
 LAMBERT.  WARNER-LAMBERT shall be under no liability whatsoever to
 compensate PFIZER or make any other payment to PFIZER for any decision to
 recall, initiate a market withdrawal or take any other corrective action
 with respect to the Products contemplated in this Section 8.07, unless such
 action results from WARNER-LAMBERT's failure to comply with the terms of
 this Agreement.

      SECTION 8.08.  Survival of Obligations.  The obligations of the
 parties set forth in Sections 8.01, 8.04, 8.05 and 8.06 shall survive the
 termination of this Agreement (or the period of time in which PFIZER
 retains co-promotion rights under Section 2.01 if shorter) for the shelf
 life of the Products containing the PFIZER Logo in accordance with Section
 2.05(c).

                 ARTICLE IX - ORDERS AND SUPPLY OF PRODUCTS

      SECTION 9.01.  Orders and Terms of Sale.  WARNER-LAMBERT shall have
 the sole right to (i) receive, accept and fill orders for Products, (ii)
 control invoicing, order processing and collection of accounts receivable
 for Product sales, (iii) record Product sales in its books of account, and
 (iv) establish and modify the commercial terms and conditions with respect
 to the sale and distribution of Products, including matters such as the
 price at which the Products will be sold and whether any discounts, rebates
 or other deductions should be made, paid or allowed.  It is understood that
 certain of the matters set forth in clause (iv) above shall be incorporated
 in the Marketing Plans developed pursuant to Section 4.01.

      SECTION 9.02.  Misdirected Orders.  If, for any reason, PFIZER
 receives orders for Products, PFIZER shall forward such orders to
 WARNER-LAMBERT (or if directed by WARNER-LAMBERT to WARNER-LAMBERT's
 wholesalers) as soon as practicable.

      SECTION 9.03.  Product Returns.  If any quantities of the Products are
 returned to PFIZER, PFIZER shall immediately notify WARNER-LAMBERT and ship
 them to the facility designated by WARNER-LAMBERT, with any reasonable or
 authorized shipping or other documented direct cost to be paid by
 WARNER-LAMBERT.  PFIZER, at its option, may advise the customer who made
 the return that the Products have been returned to WARNER-LAMBERT, but
 shall take no other steps in respect of any return without the consent of
 WARNER-LAMBERT.  All returns of Samples used by the PFIZER field force
 shall first be returned to PFIZER which shall ship them to WARNER-LAMBERT,
 at WARNER-LAMBERT's expense.

      SECTION 9.04.  Supply.  WARNER-LAMBERT shall use reasonable efforts to
 supply Products (both for trade purposes and Samples) during the Term of
 this Agreement in a consistent fashion and in sufficient quantities to meet
 the forecasted amounts of Products in accordance with the then current
 Marketing Plan.  With respect to the foregoing, WARNER-LAMBERT shall
 maintain inventory of Products (a) for the first two Agreement Quarters of
 Agreement Year One for each Country, equal to six (6) months requirement
 (based on the then current Marketing Plan) and (b) for the final two
 Agreement Quarters of Agreement Year One and the remaining Agreement Years,
 equal to three (3) months requirement (based on the then current Marketing
 Plan).  WARNER-LAMBERT may establish appropriate back-up manufacturing
 facilities and, in such event, shall be responsible for obtaining all
 Governmental or Regulatory Authority approvals for such facilities on a
 timely basis as required to prevent any interruption, discontinuity or
 other impediment to continued supply of the Products.

      SECTION 9.05.  PFIZER Back-Up Manufacturing Facilities.  If, after
 approval of a Marketing Authorization for a Product, additional back-up
 manufacturing facilities are required, PFIZER shall have the option, at its
 sole cost and expense, to request WARNER-LAMBERT to file a supplement to
 have one or more of PFIZER's or any of its Affiliate's manufacturing
 facilities (the "PFIZER Facilities") qualified and approved as back-up
 manufacturing facilities.  If PFIZER desires to have any of its facilities
 so qualified, PFIZER shall notify WARNER-LAMBERT of the identity of such
 PFIZER Facilities and the back-up manufacturing services to be provided
 promptly after PFIZER has made this determination.  WARNER-LAMBERT shall
 have the right to visit and audit such PFIZER Facilities and review all
 other appropriate technical information to determine whether such PFIZER
 Facilities are acceptable, such consent not to be unreasonably withheld.
 If approved by WARNER-LAMBERT, WARNER-LAMBERT shall have the right to
 provide reasonable technical assistance in the qualification and approval
 of such PFIZER Facilities at the cost and expense of PFIZER.  WARNER-
 LAMBERT shall be solely responsible for filing all submissions or other
 correspondence with the applicable Governmental or Regulatory Authorities
 in connection with any decision to seek approval of a PFIZER Facility as an
 additional back-up manufacturing facility.  WARNER-LAMBERT shall also be
 responsible for determining technical and other conditions set forth in any
 supplement filed with reference to this Section.  WARNER-LAMBERT shall have
 the sole right to determine whether or not to use the PFIZER Facilities in
 the event of an interruption or depletion in supply of Product and, under
 such circumstances, a separate manufacturing agreement will be entered into
 between the parties.

      SECTION 9.06.  Failure of Supply.  In the event for any reason,
 including Force Majeure (as hereinafter defined) (but excluding the failure
 of PFIZER to perform its obligations as a back-up manufacturer pursuant to
 the terms of Section 9.05, if applicable), WARNER-LAMBERT shall be unable
 in any Country to supply on a timely basis (in accordance with WARNER-
 LAMBERT's normal and customary practice) at least ninety percent (90%) of
 the orders for Product in such Country and provided that such orders are
 not materially greater than the forecasted Product requirements included in
 the then current Marketing Plan for such Country, then the following
 adjustments shall be made to the terms otherwise provided herein:

      (a)  If such failure to supply continues for two consecutive months or
 less, the Agreement Year for such Country in which such failure to supply
 occurred shall be extended by a length of time equal to two times the
 number of days during which WARNER-LAMBERT failed to supply Product as
 provided for above.

      (b)  If such failure to supply continues longer than two consecutive
 months, the Agreement Year for such Country in which such failure to supply
 occurred shall be extended by a length of time equal to four times the
 number of days during which WARNER-LAMBERT failed to supply Product as
 provided for above.

      (c)  Provided WARNER-LAMBERT's failure to meet its supply obligations
 shall not be the result of WARNER-LAMBERT's material breach of its
 obligations under this Agreement, then Sections 9.06(a) and 9.06(b) set
 forth PFIZER's sole remedy in the event WARNER-LAMBERT fails to meet the
 supply obligations set forth in this Article IX.

                    ARTICLE X - CONFIDENTIAL INFORMATION

      SECTION 10.01.  Confidential Information.  Each of PFIZER and WARNER-
 LAMBERT shall keep all Confidential Information received from the other
 with the same degree of care it maintains the confidentiality of its own
 confidential information.  Neither party shall use such Confidential
 Information for any purpose other than in performance of this Agreement or
 disclose the same to any other Person other than to such of its employees,
 agents, advisers, representatives, consultants and counsel who have a need
 to know such Confidential Information to implement the terms of this
 Agreement; provided, however, any such consultants shall be subject to
 confidentiality obligations consistent with those provided herein.  The
 party receiving the Confidential Information (the "Receiving Party") shall
 advise any employee, agent, adviser, representative, consultant or counsel
 who receives such Confidential Information of the confidential nature
 thereof and of the obligations contained in this Agreement relating
 thereto, and the Receiving Party shall ensure that all such employees,
 agents, advisers, representatives, consultants and counsel comply with such
 obligations as if they had been a party hereto.  Upon termination of this
 Agreement, or earlier if so requested in writing by the party disclosing
 the Confidential Information (the "Disclosing Party"), the Receiving Party
 shall use reasonable efforts to return or destroy all documents, tapes or
 other media containing Confidential Information in its possession, except
 that the Receiving Party may keep one copy of Confidential Information in
 the Legal Department files of the Receiving Party, solely for archival
 purposes.  Such archival copy shall be deemed to be the property of the
 Disclosing Party, and shall not be copied or distributed in any manner
 without the express prior permission of the Disclosing Party; provided,
 however, that the Receiving Party shall have the right to disclose any
 Confidential Information provided hereunder if, in the reasonable opinion
 of the Receiving Party's legal counsel, such disclosure is necessary to
 comply with the terms of this Agreement, or the requirements of any Law.
 The Receiving Party shall notify the Disclosing Party of the Receiving
 Party's intent to make such disclosure of Confidential Information pursuant
 to the proviso of the preceding sentence sufficiently prior to making such
 disclosure so as to allow the Disclosing Party adequate time to take
 whatever action the Disclosing Party may deem to be appropriate to protect
 the confidentiality of the information.

      SECTION 10.02.  Exceptions. Each of PFIZER and WARNER-LAMBERT shall be
 relieved of any and all of the obligations of Section 10.01 with respect to
 a specific item of Confidential Information if:

      (a)  such Confidential Information is in the public domain at the time
 of disclosure hereunder or subsequently comes within the public domain
 through no fault or action of the Receiving Party or any of its Affiliates;
 or

      (b)  such Confidential Information is in the possession or control of
 the Receiving Party or any of its Affiliates at the time of disclosure by
 or on behalf of the Disclosing Party or is independently discovered, after
 the date of disclosure, by the Receiving Party or any of its Affiliates
 without the aid, application or use of the Confidential Information, in
 each such case as evidenced by written records; or

      (c)  such Confidential Information is obtained by the Receiving Party
 from any third party not in violation of any confidentiality obligation to
 the Disclosing Party.

      SECTION 10.03.  Survival. The obligations and prohibitions contained
 in this Article X shall survive the expiration or termination of this
 Agreement for a period of five (5) years.

                           ARTICLE XI - COVENANTS

      SECTION 11.05.  Survival.  The provisions of this Article XI shall
 survive the expiration or termination of this Agreement.

               ARTICLE XII - PATENT AND TRADEMARK INFRINGEMENT

      SECTION 12.01.  Prosecution and Maintenance of Patents.  WARNER-
 LAMBERT shall make adequate filings for, and prosecute and maintain, all
 Patents and related applications in the Co-Promotion Territory unless
 WARNER-LAMBERT reasonably believes that any such Patent or related
 application is not material to the matters contemplated in this Agreement.
 WARNER-LAMBERT shall consult with PFIZER prior to abandoning any Patents or
 related applications that are material to the matters contemplated in this
 Agreement.  At PFIZER's reasonable request WARNER-LAMBERT shall advise
 PFIZER of the status of pending applications, shall provide PFIZER with
 copies of documentation concerning such applications and shall consult with
 PFIZER before taking any action materially affecting the scope of patent
 coverage relating to Products.  WARNER-LAMBERT shall file all applications
 and take any other actions necessary to obtain patent extensions and
 supplementary protection certificates for Patents where available in the
 Co-Promotion Territory unless WARNER-LAMBERT reasonably believes that any
 such Patent or application is not material to the matters contemplated in
 this Agreement.

      SECTION 12.02.  Patent Infringement.

      (a)  In the event any infringement action shall be brought within the
 Co-Promotion Territory against PFIZER or any of its Affiliates because of
 the manufacture, use or sale of Products, PFIZER shall promptly notify
 WARNER-LAMBERT.  WARNER-LAMBERT shall, at its sole expense, assume the
 defense of such action, and PFIZER shall be fully indemnified on account of
 such action subject to the terms of Article XI.

      (b)  If any third party shall, in the reasonable opinion of either
 party, infringe any of the Patents, such party shall promptly notify the
 other party.

      (c)  If any third party shall infringe any of the Patents in
 connection with either the manufacture, use or sale of a product in any
 Country that has a Material Adverse Effect (as hereinafter defined) on the
 Products in such Country, WARNER-LAMBERT shall bring suit and take such
 other action as it may determine is reasonably necessary to enjoin,
 prohibit, or retard such infringement.  PFIZER shall cooperate in such
 suits or actions.  In the event of such a Material Adverse Effect, the
 Agreement Year with respect to the Country involved in which such
 infringement occurred shall be extended by the number of days during which
 such infringement resulted in a Material Adverse Effect on Net Sales in
 such Country.  For purposes of this Section 12.02(c), "Material Adverse
 Effect" shall be deemed to occur if sales in such Country of infringing
 products by such infringing party equal at least ten percent (10%) of Net
 Sales in such Country in such Agreement Year.

      (d)  If any third party shall infringe any of the Patents and such
 infringement does not result in a Material Adverse Effect, WARNER-LAMBERT
 shall have sole discretion whether or not to bring suit to enjoin,
 prohibit, or retard such infringement.

      SECTION 12.03.  Trademarks.

      (a)  WARNER-LAMBERT agrees to pursue and maintain the Trademark and
 all of its relevant copyrights relating to the Products in the Co-Promotion
 Territory.  WARNER-LAMBERT and PFIZER shall each advise the other promptly
 upon its becoming aware of any infringement by a third party of the
 Trademark.

      (b)  WARNER-LAMBERT and its Affiliates shall have sole discretion to
 decide what if any action should be taken in relation to such infringement.
 PFIZER shall cooperate fully with, and as reasonably requested by, WARNER-
 LAMBERT, at WARNER-LAMBERT's expense, in any investigation or action taken
 by WARNER-LAMBERT or any of its Affiliates in respect of such infringement.
 Any sums obtained as a result of any such suit or proceeding, whether by
 judgment, award, decree or settlement, shall be the property of WARNER-
 LAMBERT or its Affiliate and PFIZER shall not under any circumstances be
 entitled to any share of the same.

      (c)  In the event any trademark infringement action shall be brought
 within the Co-Promotion Territory against PFIZER or any of its Affiliates
 because of the manufacture, use or sale of Products, PFIZER shall promptly
 notify WARNER-LAMBERT.  WARNER-LAMBERT shall, at its sole expense, assume
 the defense of such action, and PFIZER shall be fully indemnified on
 account of such action subject to the terms of Article XI.

                           ARTICLE XIII - RECORDS

      SECTION 13.01.  Detail Records.  Both parties shall keep accurate and
 complete records of each Detail carried out by it under this Agreement and
 shall make such records available for inspection, review and audit by an
 independent certified public accountant or the local equivalent appointed
 by the other party and reasonably acceptable to such party for the purpose
 of verifying the number of Details made by such party.  All costs and
 expenses incurred in connection with performing any such audit shall be
 paid by the party performing such audit.  Such accountants shall not reveal

 such information as is required to be disclosed under this Agreement, and

 provisions of Article X.

 records of Net Sales and Product Expenses as are necessary to determine
 accurately under United States generally accepted accounting principles the
 sums due to PFIZER and WARNER-LAMBERT under this Agreement.  PFIZER shall
 keep such records of its Product Expenses as are necessary to determine
 accurately under United States generally accepted accounting principles the
 sums due to PFIZER and WARNER-LAMBERT under this Agreement.  Such records
 shall be retained by each party (in such capacity, the "Recording Party")
 and shall be made available for inspection, review and audit, at any time
 during the applicable Agreement Year and for three (3) years thereafter, at
 the request and expense of the other party, by an independent certified
 public accountant or the local equivalent appointed by such other party and
 reasonably acceptable to the Recording Party for the sole purpose of
 verifying the Recording Party's accounting reports and payments made or to
 be made pursuant to this Agreement, provided that such audits may not be
 performed by either party more than once per Agreement Year.  Such
 accountants shall not reveal to the party seeking verification the details
 of its review, except for such information as is required to be disclosed
 under this Agreement, and shall be subject to confidentiality obligations
 consistent with the provisions of Article X.

      SECTION 13.03.  Retaining of Records.  The documents from which were
 calculated (i) the sums due under Article III and (ii) the number of
 Details as set forth in the written reports delivered in accordance with

 rights under Section 2.01 on a Country-by-Country basis as follows: (i)
 WARNER-LAMBERT shall give to PFIZER notice of WARNER-LAMBERT's intent to
 terminate such co-promotion rights ("Termination Notice A"), (ii)
 Termination Notice A shall specify for each affected Country a date for
 such termination of co-promotion rights which date shall be not less than

 event shall the date for termination of such co-promotion rights be earlier
 than the first day of Agreement Year Four in the affected Country, and (iv)
 in all cases the date for termination of such co-promotion rights shall be
 on the first day of an Agreement Quarter in the affected Country; and

      (b)  WARNER-LAMBERT shall have the right, at its sole discretion, to
 terminate PFIZER's co-promotion rights under Section 2.01 on a Country-by-
 Country basis as follows: (i) WARNER-LAMBERT shall give to PFIZER notice of
 WARNER-LAMBERT's intent to terminate such co-promotion rights ("Termination
 Notice B"), (ii) Termination Notice B shall specify for each affected
 Country a date for such termination of co-promotion rights which date shall
 be not less than twelve (12) months after the date of Termination Notice B,
 (iii) in no event shall the date for termination of such co-promotion
 rights be earlier than the first day of Agreement Year Six in the affected
 Country, and (iv) in all cases the date for termination of such co-
 promotion rights shall be on the first day of an Agreement Quarter in the
 affected Country.

      SECTION 14.03.  Termination of Agreement.

      (a)  At any time, upon twelve (12) months' notice to WARNER-LAMBERT,
 PFIZER shall have the right on a Country-by-Country basis, at PFIZER's sole
 discretion, to terminate this Agreement (provided the date for termination
 shall be on the first day of an Agreement Quarter), and upon such
 termination, subject to Section 14.05, PFIZER shall have no further rights
 to any payments or compensation from WARNER-LAMBERT.

      (b)  If either WARNER-LAMBERT or PFIZER materially breaches or
 defaults in the performance of any of the provisions of this Agreement, and
 such material breach or default is not cured within sixty (60) days after
 the giving of notice by the other party specifying such breach or default,
 the other party shall have the right to terminate this Agreement forthwith.
 For the purposes of this Section 14.03(b), a material breach or default in
 the performance of any of the provisions of this Agreement shall include a
 material inaccuracy in any representation, warranty or covenant contained
 herein.

      (c)  To the extent permitted by Law, if either WARNER-LAMBERT or
 PFIZER shall become insolvent, or shall make or seek to make or arrange an
 assignment for the benefit of creditors, or if proceedings in voluntary or
 involuntary bankruptcy shall be initiated by, on behalf of or against such
 party (and, in the case of any such involuntary proceeding, not dismissed
 within ninety (90) days), or if a receiver or trustee of such party's
 property shall be appointed and not discharged within ninety (90) days, the
 other party shall have the right to terminate this Agreement forthwith.

      SECTION 14.04.  Effects of Termination of Co-Promotion Rights.

      (a)  Termination by WARNER-LAMBERT under Section 14.02 shall not
 release either party from any obligation to pay to the other party any sums

 due under Article III in connection with activities completed on or before
 the effective date of such termination, but no further sums shall be
 payable under Article III except as provided in Sections 14.04 or 14.05.

      (b)  If PFIZER's co-promotion rights for any Country are terminated by
 WARNER-LAMBERT pursuant to Sections 14.02(a) or 14.02(b), WARNER-LAMBERT
 shall pay to PFIZER seventy-five percent (75%) of the payment(s) PFIZER
 would have received pursuant to Article III through the end of Agreement
 Year Ten for such Country.  In computing such amounts there shall be
 deducted the amounts PFIZER would have owed WARNER-LAMBERT pursuant to
 Section 3.01(b) with respect to the remaining Agreement Years had PFIZER's
 co-promotion rights not been terminated; provided that PFIZER shall have no
 obligations under Section 3.01(b) to actually pay or incur any Product
 Expenses after PFIZER's co-promotion rights are terminated under Sections
 14.02(a) or 14.02(b).  It is understood that payments for each such
 remaining Agreement Year shall be based on the actual Net Sales and Product
 Expenses, in each case for such Agreement Year as provided in this
 Agreement.  Moneys shall be payable in the manner and at such times as set
 forth in Sections 3.03 and 3.04 for each Agreement Quarter during such
 remaining Agreement Years.  In addition, WARNER-LAMBERT shall continue to
 comply with all its marketing, detailing, promotional and clinical
 obligations under this Agreement as if PFIZER had retained its co-promotion
 rights.  In addition, WARNER-LAMBERT (or such other co-promotion partner as
 WARNER-LAMBERT shall appoint) shall assume the marketing, detailing and
 promotional obligations that PFIZER would have been responsible for
 pursuant to this Agreement had the Agreement not been terminated, and
 PFIZER shall have no responsibility therefor.

      SECTION 14.05.  No Prejudice to Rights.  Termination of this Agreement
 shall be without prejudice to:

      (a)  The rights of the parties to any payments due under Article III
 to the date of termination; and

      (b)  Any remedies which either party may then have hereunder or at
 law; and

      (c)  Either party's right to obtain performance of any obligations
 provided for in this Agreement which survive termination by their express
 terms.

      SECTION 14.06.  Return of Confidential Information.  (a)  Subject to
 the terms of Section 10.01 and 14.06(b), upon the termination of this
 Agreement (or, if earlier, the termination of PFIZER's co-promotion
 rights), (i) PFIZER shall within thirty (30) days return to WARNER-LAMBERT
 all Samples, Promotional Materials, communications materials, marketing
 plans and reports and other tangible WARNER-LAMBERT Confidential
 Information provided to PFIZER by or on behalf of WARNER-LAMBERT pursuant
 to the terms and intent of this Agreement, and (ii) WARNER-LAMBERT shall
 within thirty (30) days return to PFIZER all tangible PFIZER Confidential
 Information provided to WARNER-LAMBERT by or on behalf of PFIZER pursuant
 to this Agreement.

      (b)  If PFIZER's co-promotion rights are terminated by WARNER-LAMBERT
 pursuant to Section 14.02, then, WARNER-LAMBERT shall reimburse PFIZER for
 the Product Expenses incurred by PFIZER pursuant to Section 3.01(b) with
 respect to the Samples and Promotional Materials returned to WARNER-LAMBERT
 pursuant to Section 14.06(a).  This payment shall be made by WARNER-LAMBERT
 within sixty (60) days of PFIZER's return of such Samples in accordance
 with the terms of Section 14.06(a).

                         ARTICLE XV - MISCELLANEOUS

      SECTION 15.01.  Relationship of the Parties.  Each party shall bear
 its own costs incurred in the performance of its obligations hereunder
 without charge or expense to the other except as expressly provided in this
 Agreement.  Neither party shall have any responsibility for the hiring,
 termination or compensation of the other party's employees or for any
 employee benefits of such employee.  No employee or representative of a
 party shall have any authority to bind or obligate the other party to this
 Agreement for any sum or in any manner whatsoever, or to create or impose
 any contractual or other liability on the other party without said party's
 approval.  For all purposes, and notwithstanding any other provision of
 this Agreement to the contrary, PFIZER's legal relationship under this
 Agreement to WARNER-LAMBERT shall be that of independent contractor.
 Nothing in this Agreement shall be construed to establish a relationship of
 co-partners or joint venturers between the parties.

      SECTION 15.02.  No Solicitation.  The parties agree that during the
 Term of this Agreement neither party shall solicit any employee of the
 other party, with whom it has come in contact or interacted for the
 purposes of the performance of this Agreement, to leave the employment of
 the other party and accept employment with the first party.

      SECTION 15.03.  Force Majeure.  The occurrence of an event which
 materially interferes with the ability of a party to perform its
 obligations or duties hereunder which is not within the reasonable control
 of the party affected, not due to malfeasance, and which could not with the
 exercise of due diligence have been avoided ("Force Majeure"), including,
 but not limited to, fire, accident, labor difficulty, strike, riot, civil
 commotion, act of God, delay or errors by shipping companies or change in
 Law, shall not excuse such party from the performance of its obligations or
 duties under this Agreement, but shall merely suspend such performance
 during the continuation of Force Majeure.  The party prevented from
 performing its obligations or duties because of Force Majeure shall
 promptly notify the other party hereto (the "Other Party") of the
 occurrence and particulars of such Force Majeure and shall provide the
 Other Party, from time to time, with its best estimate of the duration of
 such Force Majeure and with notice of the termination thereof. The party so
 affected shall use reasonable efforts to avoid or remove such causes of
 nonperformance.  Upon termination of Force Majeure, the performance of any
 suspended obligation or duty shall promptly recommence.  Neither party
 shall be liable to the Other Party for any direct, indirect, consequential,
 incidental, special, punitive, exemplary or other damages arising out of or
 relating to the suspension or termination of any of its obligations or
 duties under this Agreement by reason of the occurrence of Force Majeure.

      SECTION 15.04.  Confidentiality; Public Announcements.

      (a)  Each party shall keep the terms of this Agreement confidential
 and shall not disclose the same to any third party other than (i) by
 agreement of the parties hereto, or (ii) as required by Law or stock
 exchange regulation or an order of a competent court; provided that prior
 to disclosure pursuant to (ii) above, the disclosing party shall notify the
 nondisclosing party sufficiently prior to making such disclosure so as to
 allow the nondisclosing party adequate time to take whatever action it may
 deem to be appropriate to protect the confidentiality of the information.

      (b)  Neither party shall make any press release or other public
 announcement or other disclosure to third parties relating to this
 Agreement without the prior consent of the other party, which consent shall
 not be unreasonably withheld, except where required by applicable Law;
 provided that prior to disclosure, the disclosing party shall notify the
 nondisclosing party sufficiently prior to making such disclosure so as to
 allow the nondisclosing party adequate time to take whatever action it may
 deem to be appropriate to protect the confidentiality of the information.

      SECTION 15.05.  Choice of Law; Submission to Jurisdiction.  This
 Agreement shall be governed by and construed in accordance with the law of
 the State of New York other than those provisions governing conflicts of
 law.  Each party hereby irrevocably and unconditionally submits for itself
 and its property in any legal action or proceeding relating to or arising
 out of this Agreement, or any of the transactions contemplated hereby, to
 the non-exclusive general jurisdiction of the Courts of the State of New
 York, the courts of the United States of America for the Southern District
 of New York, and appellate courts from any thereof, and agrees that any
 such action or proceeding may be brought in such courts.

      SECTION 15.06.  Assignment.  This Agreement may not be assigned by
 either party without the prior consent of the other party; provided that
 each party shall have the right to assign its rights and obligations under
 this Agreement to (a) any third party successor to all or substantially all
 of (i) its entire business or (ii) its pharmaceutical business or (b) in
 whole or in part to its Affiliate or Affiliates who shall be substituted
 directly in whole or in part for it hereunder; provided however, that the
 assignor shall be responsible for the performance of its Affiliate
 assignee(s) hereunder. It is further understood and agreed that each party
 shall assign, or otherwise cause to be performed, its obligations under
 this Agreement (including, without limitation, obligations of
 confidentiality, detailing, payment and promotion) to or by, as the case
 may be, one or more of its Affiliates to the extent necessary or
 appropriate in order to ensure that such obligations are fulfilled in
 accordance with the terms and intent of this Agreement. This Agreement
 shall be binding upon, and subject to the terms of the foregoing sentence,
 inure to the benefit of the parties hereto, their successors, legal
 representatives and assigns.

      SECTION 15.11.  Entire Agreement.  This Agreement (including Exhibits

 trade secret or other data or any other intellectual property of the other
 party except as expressly set forth herein.

      SECTION 15.13.  Independent Agreements.  WARNER-LAMBERT and PFIZER

 the parties will in the future negotiate and, if such negotiations are
 successful, enter into additional agreements regarding such PFIZER
 compound.  It is recognized that the parties may fail to reach any future
 agreement or agreements contemplated under the Option Agreement, or the
 Option Agreement may terminate, or disputes may arise under the Option
 Agreement or in connection with any transactions contemplated thereunder,
 or WARNER-LAMBERT may not acquire or be granted any rights to any PFIZER
