      generality of the foregoing, the responsibilities of each respective Board
      shall include: approval of business plans, long range plans, annual sales
      and profit targets, and capital forecasts for each combination. The Boards
      shall carry out their responsibilities as set forth in this Agreement and
      the Related Agreements, as applicable, and shall have the authority to
      approve or disapprove any recommendation of the General Manager or any
      Committee under this Agreement and the Related Agreements, as applicable.
      With respect to matters not the subject of recommendation by any Committee
      or the General Manager under this Agreement or the Related Agreements, as
      applicable, no business may be transacted on behalf of a Company without
      the prior written consent or written authorization of the applicable
      Board. Without limiting the generality of the foregoing, only the
      applicable Board may authorize the expenditure of funds by or on behalf of
      a


                                     - 20 -

      Company (unless specifically delegated to a Committee or the General
      Manager or pursuant to any plan approved by the Board of such Company or
      as otherwise set forth in Section 3.7). The Boards shall operate
      independently of the Members and all lawful determinations, decisions and
      actions made or taken by the applicable Board shall be conclusive and
      absolutely binding upon the applicable Company. Prior to establishment of
      the Boards, the Companies will be managed by the Members.

            (b) Membership. The Boards shall be composed of an equal number of
      representatives appointed by the S-P Members on the one hand and the M
      Members on the other. Each of the Boards (other than the Board of the
      Singapore Partnership) shall initially be comprised of three (3) senior
      executives of S-P or any of its Affiliates, on the one hand, and three (3)
      senior executives of M or any of its Affiliates, on the other. The Board
      of the Singapore Partnership shall initially be comprised of five (5)
      senior executives of S-P or any of its Affiliates and five (5) senior

      of S-P and M, or any of their Affiliates, shall reside outside of the
      United States (including one of whom shall reside in Singapore), and at
      least one of the five such members shall have expertise in research and
      development matters. The applicable Members may change the size and/or
      composition of any of the Boards from time to time by mutual written
      consent of each of the S-P Members and the M Members. The members of each
      such Board shall not be responsible for day to day competition-related
      decisions of S-P or M or any of their Affiliates with respect to products
      competing with the Cholesterol Products. Each of the members of the Boards
      shall (i) enter into an appropriate confidentiality agreement with the
      applicable Companies, the Members and S-P or M, as the case may be, which
      such agreement shall prohibit the unauthorized use or disclosure of
      Confidential Information obtained from any of the Companies, the Members,
      or S-P and M, or any of their Affiliates, and appropriate restrictions
      shall be established to govern to the extent necessary the distribution to
      the members of the Board of certain materials relating to pricing, pricing
      strategies, marketing and/or marketing strategies for products or
      prospective products of either S-P or M, or any of their Affiliates. The
      S-P Members on the one hand and the M Members on the other may replace any
      of its Board representatives with another senior executive of S-P or any
      of its Affiliates, or M or any of its Affiliates, as the case may be,
      provided that such replacement satisfy the residency and expertise
      requirements, if any, of the representative being replaced, at any time
      upon written notice to the other party and the Company. The Board of each
      of Distribution LLC and Marketing LLC shall be chaired by a representative
      selected by the M Board Members (each, a "Board Chairperson"). The Board
      of the Singapore Partnership shall be chaired by two individuals, one
      representative selected by the S-P Members and one representative selected
      by the M Members (each, a "Co-Chairperson"). The applicable Board
      Chairperson or Co-


                                     - 21 -

      Chairperson, in the case of the Singapore Partnership, shall have as his
      and/or her function as Chairperson the responsibility for calling
      meetings, preparing and circulating an agenda in advance of each meeting,
      and preparing and, subject to the prior review and approval of the Board,
      issuing minutes of each meeting within thirty (30) days thereafter. From
      time to time, the Boards may establish subcommittees or subordinate
      committees (which may or may not include members of the applicable Board
      itself) to oversee particular projects or activities, and such
      subcommittees or subordinate committees shall be constituted and shall
      operate as the applicable Board agrees.

            (c) Meetings of the Boards. The Boards shall hold regular meetings
      no less frequently than once every quarter, unless the Board otherwise
      determines. Special meetings of the Boards may be called by any Board
      member or as otherwise determined by the applicable Board. Meetings, in
      addition to quarterly meetings, shall be held timely to approve Plans
      submitted for Board approval in accordance with this Agreement and the
      Related Agreements, as applicable. Meetings of the Boards may be held by
      audio or video teleconference. The S-P Members on the one hand and the M
      Members on the other shall be responsible for all of their own expenses of
      having their representatives participate on a Board. All meetings of the
      Board of the Singapore Partnership shall be held outside the United
      States. All meetings of the Boards of the Companies other than the
      Singapore Partnership shall be held in the state of Nevada or at such
      other location as each such Board may determine.

            (d) Manner of Acting. Meetings of a Board shall be effective only if
      two representatives of the S-P Members on the one hand and two
      representatives of the M Members on the other are present or participating
      throughout. The unanimous vote of the members of a Board present or
      participating at any meeting of a Board shall be necessary for the passage
      of any resolution or act of a Board. Any action required or permitted to
      be taken by a Board may be taken without a meeting if each member of a
      Board consents thereto in writing.

            (e) Dispute Resolution. Except as set forth in Section 7.1(b)
      [Product Safety], the members of each Board will use reasonable efforts to
      resolve any dispute, claims, controversies or disagreements, including
      without limitation matters referred to it by a Committee under Section
      3.6(b) [Committee Dispute Resolution]. If any matter cannot be resolved by
      the applicable Board within a reasonable period of time, such
      reasonableness to be considered in view of the urgency and importance of
      the matter, and in any event, within thirty (30) days after the
      representative(s) of the S-P Members on the one hand or the M Members on
      the other on the applicable Board has given written notice of such
      disagreement to the representative(s) of the other party, the S-P Members
      on the one hand and the M Members on the other shall cause to be prepared
      and circulated to the other party a memorandum or other form of statement
      setting out its position on the matter in dispute and its reasons for
      adopting such position.


                                     - 22 -

      Each such memorandum or statement shall be considered by the respective
      Executive Sponsor of the S-P Members or the M Members. The respective
      Executive Sponsors of the S-P Members and the M Members shall use their
      respective good faith reasonable efforts to jointly recommend a resolution
      of such dispute to the applicable Board within thirty (30) days. Upon
      resolution of the matter the respective Executive Sponsors shall jointly
      execute a written statement setting forth the terms of such recommended
      resolution.

            (f) Executive Sponsors. Each of M and S-P will designate one senior
      executive of it or any of its Affiliates (who may also serve as a member
      of the Board) to serve as that party's "Executive Sponsor" to champion
      interactions between the S-P Members on the one hand and the M Members on
      the other with respect to the Cholesterol Business.

      "Development Committee") which shall be comprised of members designated in
      a manner, and have the responsibilities and duties, and which shall be
      subject to any other provisions related to the Development Committee or
      any members of such Committee, as set forth in the Development Agreement;

      the Marketing Committee or any members of such Committee, as set forth in
      the Co-Promotion Agreement; and (c) a Finance Committee (the "Finance
      Committee") which shall oversee and coordinate the financial affairs of
      the Companies and which shall meet at least once every six (6) months. The
      Committees shall operate independently of S-P, M and the Members, and in
      the best interests of the Companies.

            (b) Principles. Members of a Marketing Committee shall be persons at
      a sufficiently high level within M or S-P or their Affiliates to exercise
      substantive input with respect to matters presented to such Committee.
      Members of the Marketing Committee may have other responsibilities within
      M or S-P or their Affiliates including among other things, general
      oversight of the marketing and/or sales of products in the Field, but not
      primary day-to-day responsibility for products in the Field. Each of the
      members of the Committees shall enter into an appropriate confidentiality
      agreement with the applicable Companies, the Members, and S-P or M, as the
      case may be. Such confidentiality agreement shall prohibit the
      unauthorized use or disclosure of Confidential Information obtained from
      any of the Companies, the Members, S-P and M or any of their respective
      Affiliates. From time to time, each Committee may establish subcommittees
      or subordinate committees (which may or may not include members of the
      Committee itself) to oversee particular projects or activities, and such


                                     - 23 -

      subcommittees or subordinate committees shall be constituted and shall
      operate as the Committee agrees.

            (c) Scope of Committee Authority. The activities of the committees
      described in Section 3.4(a) shall be limited to making recommendations to
      the General Manager and the Boards of the appropriate Companies. The
      committees shall have no express or implied authority to act on behalf of
      any Company or cause any Company to act, except as otherwise authorized by
      the Board of each such Company.

      Section 3.5. Meetings of the Committees. Each Committee shall hold
meetings at such times and in such manner as set forth in the appropriate

      representatives of the M Members on the other are present or participating
      throughout. The unanimous vote of the members of a Committee present or
      participating at any meeting of a Committee shall be necessary for the
      passage of any resolution or act of a Committee. Subject to Section 3.5,
      any action required or permitted to be taken by a Committee may be taken
      without a meeting if each member of a Committee consents thereto in
      writing.

            (b) Committee Dispute Resolution. Subject to the provisions in
      Section 7.1(b) [Product Safety], if any matter cannot be resolved by a
      Committee within a reasonable period of time, such matter shall be
      submitted to the applicable Board for resolution as set forth in Section
      3.3(e).

      reasonable efforts to avoid the entry of any decree, judgment, injunction
      or other order, whether temporary, preliminary or permanent, under any

      substance reasonably acceptable to S-P. The S-P Marks shall only be used
      as reasonably determined by the applicable Board, except as specifically
      provided in the Related Agreements.

                                   ARTICLE VI
                              RIGHT OF FIRST OFFER

      Section 6.1. Right of First Offer.

            (a) Unless and until an agreement which provides for the marketing,
      distribution and sale of the Cholesterol Products in the ROW has been
      executed and delivered by M and S-P or their respective Affiliates,
      neither M or S-P or any of their Affiliates shall enter into discussions
      or negotiations with any Third Party (other than a Pre-Existing
      Relationship) regarding any business arrangement either with itself or any
      of its Affiliates for the marketing, sale, promotion or any similar
      commercial activities of any of the Cholesterol Products in any country in
      the ROW (a "ROW Arrangement") unless the party interested in pursuing such
      discussions or negotiations (the "Offering Party") first submits in
      writing to the


                                     - 29 -

      other party (the "Other Party") a good faith offer containing the terms on
      which it would agree to enter into a ROW Arrangement for the applicable
      country with the Other Party. The Other Party must accept in writing
      within 20 business days of the delivery of such offer in order to accept
      such offer. In the event that the Other Party rejects such offer in
      writing, or fails to accept within such period (the earlier of such dates,
      the "Rejection Date"), the Offering Party may enter into discussions with
      Third Parties regarding such a ROW Arrangement.

            (b) The Offering Party may, within 180 days after the Rejection
      Date, enter into a ROW Arrangement with the Third Party on the same
      financial and economic terms and, to the extent feasible, substantially
      the same other terms as offered to the Other Party, and which such other
      terms shall, in the aggregate, be no more favorable to the Third Party
      than those offered to the Other Party. The Offering Party will provide the
      Other Party with prompt written notice of the entering into of any such
      agreement. In the event the Offering Party desires to enter into a ROW
      Arrangement on financial and economic terms which are not the same, or
      which would not have substantially the same other terms to the extent
      feasible, as those previously offered, and which such other terms are, in
      the aggregate, more favorable to the Third Party than those offered to the
      Other Party, or after the expiration of such 180-day period, the
      provisions of this Section 6.1 shall apply again.

            (c) For purposes of clarity, the parties hereto agree and
      acknowledge that no license rights are implied, granted or otherwise arise
      pursuant to this Section 6.1

            (d) For a 90-day period following the date of execution of this
      Agreement, S-P and M shall negotiate exclusively concerning a business
      arrangement for the development, marketing, sale, promotion or any similar
      commercial activities of all of the Cholesterol Products in the ROW
      together with Japan, provided that this exclusive negotiation period shall
      not be construed as an obligation of the parties to enter into a final,
      binding agreement with respect to such markets.

                                   ARTICLE VII
                  DISPUTE RESOLUTION, TERMINATION, DISSOLUTION
                                 AND LIQUIDATION

      Section 7.1. Dispute Resolution.

            (a) General. Except as set forth in Section 7.1(b) (and without
      limiting any dispute resolution procedures and remedies specifically
      provided in any of the Related Agreements), any and all disputes, claims,
      controversies or disagreements with respect to this Agreement or any of
      the Related Agreements shall be resolved pursuant to the procedures set
      forth in Section 3.3(e) and Section 3.6(b), as


                                     - 30 -

      applicable, and each of S-P, M and the Members agree that none of them
      shall, except as contemplated by Section 9.14 [Judicial Proceeding],
      resort to any means whatsoever, including litigation, arbitration,
      dissolution by a judicial forum or decree, or by operation of law,
      appointment of a trustee, receiver, custodian or similar person, or to any
      other form of proceeding in connection with any such dispute, claim,
      controversy or disagreement, including, without limitation, pursuant to
      Section 86.491 of the Nevada Limited Liability Company Act, Section 18-802
      of the Delaware Limited Liability Company Act and other similar applicable
      laws.

            (b) Product Safety. The Development Committee will use good faith
      reasonable efforts to resolve disputes relating to product safety. If
      unsuccessful, the Board of the Singapore Partnership and then the
      Presidents of Research and Development for each of S-P and M will use
      reasonable efforts to resolve such dispute. If the Presidents of Research
      and Development for each of S-P and M are unable to resolve such dispute,
      the respective Chief Executive Officers of each of S-P and M shall use
      their good faith reasonable efforts to resolve such dispute.

      Section 7.2. Termination. This Agreement may be terminated and the
provisions of Section 7.3 shall apply, as follows:

            (a) Regulatory Approval. By M or S-P, in the event that the
      applicable waiting periods under the HSR Act with respect to the
      Cholesterol Business shall not have expired or been terminated prior to
      the twelve month anniversary of the date hereof; or

            (b) Bankruptcy. By M, in the event of the Bankruptcy of S-P or any
      of its Significant Subsidiaries and, by S-P, in the event of the
      Bankruptcy of M or any of its Significant Subsidiaries; or

            (c) Material Breach. By M, in the event of a Material Breach (as
      defined below) by S-P or one of its Affiliates of its obligations under
      this Agreement or one or more of the Related Agreements or, by S-P, in the
      event of a Material Breach by M or one of its Affiliates of its
      obligations under this Agreement or one of the Related Agreements, which
      breach is not cured by the breaching party or its Affiliates within thirty
      (30) days, or such longer period as specifically provided pursuant to the
      Related Agreements, after receipt by the breaching party and its ultimate
      parent, M or S-P, as the case may be, of written notice of the breach
      requesting cure of the breach, with reasonable detail of the particulars
      of the alleged breach or in the event that the breach cannot be reasonably
      cured within such thirty (30) day period, or such longer period as
      specifically provided pursuant to the Related Agreements, the other party
      or its Affiliate has not initiated actions reasonably expected to cure the
      cited failure within thirty (30) days of receiving notice and has not in
      any event cured such breach within 120 days of receiving notice, or such
      longer period as specifically


                                     - 31 -

      provided pursuant to the Related Agreements. For purposes of this Section
      7.2(c), "Material Breach" means a breach of a material provision of this
      Agreement or any of the Related Agreements that (i) results in a material
      adverse effect on the business, operations or financial condition of the
      Companies taken as a whole, or the value of the Companies taken as a
      whole, and (ii) materially frustrates the ability of either S-P or M, as
      the non-breaching party, as the case may be, to realize the reasonably
      anticipated benefits from the Companies ("Material Adverse Effect"). A
      Material Breach shall also be deemed to occur upon any breach of Section
      9.9 of this Agreement, provided that if an alleged breach is by a Person
      that has been determined to be an Affiliate of M or S-P, as the case may
      be, such breach will not be deemed a Material Breach if M or S-P, as the
      case may be, demonstrates by a preponderance of the evidence each of the
      following (i) that it did not cause, assist or encourage such Affiliate to
      take the action underlying the alleged breach, (ii) that it did not have
      the power to prevent such Affiliate from taking such action and (iii) that
      it used commercially reasonable efforts to prevent such Affiliate from
      taking such action. Notwithstanding the prior sentence, such breach may,
      however, nevertheless be determined to be a Material Breach pursuant to
      the provisions of the next sentence. The determination of whether a
      Material Breach has occurred and liability for such breaches shall be made
      in a judicial proceeding pursuant to Section 9.14 [Judicial Proceeding];
      or

            (d) Change of Control. By S-P, in the event of a Change of Control
      of M, or by M, in the event of a Change of Control of S-P, as the case may
      be; or

      Section 7.3. Consequences of Termination.

            (a) General. With respect to any event of termination, each party
      shall undertake, during the pendency of the procedure to determine whether
      such event of termination has occurred and the implementation of the
      consequences of such termination, to maintain the Cholesterol Business as
      a going concern, so that all of the rights, title and interests in the
      Companies and the Cholesterol Businesses may be conveyed. The parties
      acknowledge that in the event of a termination of this Agreement that
      results in one party acquiring the Interests of another party hereto, the
      acquiring party may determine to continue operating the Cholesterol
      Business through one or more of the Companies.

            (b) Regulatory Approval. In the event of termination pursuant to
      Section 7.2(a), either S-P or M shall have the right, exercisable by
      delivery of written notice to the other, to require such reasonable
      actions be taken so as to put each of S-P and M back, to the maximum
      extent possible and as promptly as practicable, to the position they were
      in prior to their and their Affiliates' respective contributions of the
      assets to the Companies. The costs and expenses of any such actions shall
      be borne equally by M and S-P.


                                     - 32 -

            (c) Bankruptcy. In the event of termination pursuant to Section
      7.2(b), the non-bankrupt party (or its designee) shall be entitled to
      purchase the bankrupt party's Interests in each of the Companies. Such
      purchase and sale shall be consummated as soon as practicable, but in any
      event within 300 days of determination of a Bankruptcy of the other, and
      each of the parties shall execute such documents as are reasonable and
      necessary in connection therewith. The purchase price for any such
      purchase shall be an amount equal to the fair market value of the bankrupt
      party's Interests determined in the manner described in Section 7.3(e)(i).

            (d) Material Breach.

                  (i) In the event of termination pursuant to Section 7.2(c),
            the non-breaching party (or its designee) shall be entitled to
            purchase the breaching party's Interests in each of the Companies.
            Such purchase and sale shall be consummated as soon as practicable,
            but in any event within 120 days of determination of a Material
            Breach and the related appraisal and damage proceedings, and each of
            the parties shall execute such documents as are reasonable and
            necessary in connection therewith. The purchase price for any such
            purchase shall be an amount equal to the fair market value of the
            breaching party's Interests as determined in a judicial proceeding
            as set forth in Section 9.14. In determining the fair market value
            of the breaching party's Interests, the court shall apply the
            standards applicable in an appraisal proceeding under Section 262 of
            the Delaware General Corporation Law as may be amended from time to
            time.

                  (ii) Any termination of this Agreement or any of the Related
            Agreements pursuant to this Section 7.3(d) due to a breach of this
            Agreement or any of the Related Agreements shall not relieve the
            breaching party from liability for damages caused by its breaches
            (except that the breaching party shall not be liable for punitive,
            special, consequential, incidental, indirect or exemplary or other
            similar damages or lost profits) as a result of any such breach.
            Damages shall be determined in the judicial proceeding contemplated
            by this Section 7.3(d).

            (e) Change of Control. Within 45 days after the date of a Change of
      Control of S-P or Change of Control of M, the party which did not
      experience the Change of Control (the "Call Party") may by written notice
      (the "C-O-C Notice") delivered to the other party (the "C-O-C Party")
      request that the fair market value of the C-O-C Party's Interests (the
      "Call Price") be determined in accordance with paragraph (i) of this
      Section 7.3(e).

                  (i) The Call Price shall be conclusively determined by two
            internationally recognized investment banking firms, one of which
            shall be retained and paid by the Call Party and one of which shall
            be retained and


                                     - 33 -

            paid by the C-O-C Party. The Call Party and the C-O-C Party shall
            promptly notify each other of their respective selections. If either
            such party fails to deliver such notice to the other party of its
            selection of an investment banking firm within 30 days after
            delivery of a C-O-C Notice, the determination shall be rendered by
            the single investment banking firm so selected (whose fees, in such
            case, shall be borne equally by S-P and M). The investment banking
            firms selected in accordance with the foregoing procedure shall each
            determine the fair market value of the C-O-C Party's Interest,
            (which value shall be an amount determined assuming that the buyer
            and seller are under no compulsion to buy or sell and shall be
            determined without regard to any minority or illiquidity discount)
            and submit their determinations of such value to the Call Party and
            the C-O-C Party within 45 days following their selection. The Call
            Price shall be the amount equal to the sum of such values determined
            by each investment banking firm divided by two, except that if there
            is more than a 12% difference between (x) the average of such values
            and (y) each of such values, the two investment banking firms shall,
            within 20 days after their submissions mutually select and appoint a
            third investment banking firm, similarly qualified, and give written
            notice thereof to the Call Party and the C-O-C Party. If the two
            investment banking firms fail to appoint a third investment banking
            firm within such 20-day period, the third investment banking firm
            shall be selected and appointed, at the request of either party, by
            the President of the Association of the Bar of the City of New York
            or by a person designated by such President. Within 30 days after
            the appointment of the third investment banking firm, the third
            investment banking firm shall promptly submit in writing to the Call
            Party and the C-O-C Party its determination of the fair market
            value. If the valuation of the third banker is not between the
            valuations of the first and second bankers, fair market value shall
            be the average of the valuations of the third banker and the next
            closest valuation. If the valuation of the third banker is (i)
            between the valuations of the first and second bankers and (ii) not
            more than 30% (calculated as the average of the first two valuations
            multiplied by 0.3) higher or lower than the valuations of each of
            the first and second bankers, then fair market value shall be the
            average of the valuations of all three bankers. If the valuation of
            the third banker is (x) between the valuations of the first and
            second bankers and (y) more than 30% (calculated as the average of
            the first two valuations multiplied by 0.3) higher or lower than one
            or both of the other two valuations, then fair market value shall be
            the average of the third banker's valuation and the valuation, if
            any, that is not more than 30% (calculated as the average of the
            first two valuations multiplied by 0.3) higher or lower than the
            third banker's valuation. For illustrative purposes only, Schedule
            7.3 hereof sets forth examples of the method of determining fair
            market value pursuant to the provisions of this Section 7.3(e). The
            fair market value as


                                     - 34 -

            determined above shall be final and binding upon the Call Party and
            the C-O-C Party. The cost of such third investment banking firm
            shall be borne one-half by the Call Party and one-half by the C-O-C
            Party.

                  (ii) The Call Party shall have the right, exercisable by
            delivery of written notice to the C-O-C Party (a "Call Notice")
            within 60 days after the final determination of the Call Price, to
            require the C-O-C Party to sell the C-O-C Party's entire Interest to
            the Call Party (or its designee) at a price equal to the Call Price.
            Any such sale shall be made without representations or warranties of
            the C-O-C Party other than regarding the authorization of the sale
            and title to the Interest being sold. Upon and after the
            consummation of such sale, the C-O-C Party shall have no
            responsibility or liability for any liabilities or obligations of
            the Companies (whether contingent, absolute, realized or unrealized)
            that exist as of the date of such sale or that are incurred by the
            Companies thereafter.

                  (iii) Any purchase and sale of the C-O-C Party's Interest
            effected pursuant to this Section 7.3(e) shall be consummated at a
            closing at the offices of the Call Party on a business day within 15
            days following the delivery of the Call Notice (upon at least five
            days' notice by the Call Party); provided that such period shall be
            extended for 180 additional days, or such shorter period of time, as
            shall be necessary in order to obtain requisite governmental or
            regulatory approvals with respect to such transaction; provided,
            further, that such closing may be held at such other time and place
            as the parties to the transaction may agree. At such closing, the
            Call Party shall pay the C-O-C Party the Call Price by wire transfer
            of immediately available funds to an account specified by the C-O-C
            Party, and the Company and the parties to such transaction shall
            execute any and all documents necessary to effect the full and
            complete transfer of the C-O-C Party's Interest.

                  (iv) No investment banking firm selected by a party pursuant
            to this Section 7.3(e) shall have represented such party in a
            significant engagement within the 24-month period immediately prior
            to such selection. Any investment banking firm selected in any other
            manner shall not have represented either party in a significant
            engagement within the 24-month period immediately prior to such
            selection.

            (f) Survival of Certain Related Agreements. In the event of any
      termination of this Agreement pursuant to Sections 7.2(b) [Bankruptcy],
      (c) [Material Breach], or (d) [Change of Control], the Related Agreements
      entered into by the breaching party, the bankrupt party or the party
      experiencing the Change or Control (or its Affiliates) shall,
      notwithstanding anything to the contrary contained therein, remain in
      effect as provided therein.


                                     - 35 -


            (g) Survival of Certain Provisions of this Agreement. In the event
      of any termination of this Agreement pursuant to Sections 7.2(b)
      [Bankruptcy], (c) [Material Breach] or (d) [Change of Control]:

                  (i)   All provisions of Section 9.1 [Confidentiality] shall
                        survive and continue to be binding on the Terminated
                        Party in all respects for six years following such
                        termination.

                  (ii)  All provisions of Section 9.1 (other than Sections
                        9.1(a)(i) and (a)(iii)) shall survive and continue to be
                        binding on the Non-Terminated Party for six years
                        following such termination, provided that if the
                        Terminated Party's Interests are not acquired by the
                        Non-Terminated Party, all provisions of Section 9.1
                        shall survive and continue to be binding on the
                        Non-Terminating Party for six years following such
                        termination.

                  (iii) Section 4.3 [Non-Compete] with respect to ezetimibe
                        (whether monotherapy, combination or retained uses) (it
                        being understood that all CAIs other than ezetimibe are
                        addressed in clause (iv) of this Section 7.3(g)) shall
                        survive and continue to be binding on the Terminated
                        Party and its Affiliates, as the case may be, until the
                        expiration of the last to expire U.S. patents (and any
                        marketing exclusivity period attendant thereto) owned by
                        or licensed to any of the Companies which claim or cover
                        (A) ezetimibe or (B) a combination of ezetimibe and a

                  (iv)  All other provisions of Section 4.3 shall survive and
                        continue to be binding on the Terminated Party and its

                        in the event of a Change of Control), but only with
                        respect to Pre-Termination Substances, until the later
                        of (A) four years following such termination or (B) four
                        years after the Launch of a Combination Product,
                        provided that the maximum survival period under this
                        clause (B) shall be five years after termination of this
                        Agreement.

                  (v)   All provisions of Sections 8.1, 8.2, 8.4 and 8.5 shall
                        survive for two years following termination.

            (i) Agreement to Enter into New Agreements. In the event that (i)
      this Agreement is terminated pursuant to [***] and (ii) S-P resolves the
      issues that M believed constituted a [***], as the case may be, S-P will

      marketing of ezetimibe and the Z/E Combination Product from the date of
      termination of this Agreement until the execution date of the New

      arrangements, as well as changes in law or corporate organization.

      Section 8.1. Representations and Warranties of the Parties. Each of M and
the M Members hereby represents and warrants to S-P and the S-P Members with
respect to itself and each of S-P and the S-P Members hereby represents and
warrants to M and the M Members with respect to itself as of the date hereof as
follows:

            (a) Organization and Good Standing; Power and Authority;

      Related Agreements to which it is a party.

            (b) Authorization of this Agreement and the Related Agreements. The
      execution, delivery and performance of each of this Agreement and the
      Related Agreements has been duly authorized by all requisite action on the
      part of such party which is a party hereto and thereto, and each of this
      Agreement and the Related Agreements constitutes a legal, valid and
      binding obligation of such party which is a party hereto and thereto,
      enforceable against each such party in accordance with its terms except to
      the extent that enforceability may be limited


                                      -37-

      by bankruptcy, insolvency or other similar laws affecting creditors'
      rights generally.

            (c) No Conflict. The execution and delivery by such party of this
      Agreement and the Related Agreements to which it is a party and the
      consummation by such party of the transactions contemplated hereby and
      thereby and the compliance by such party with the provisions hereof and
      thereof will not (i) violate any material provision of law, statute, rule
      or regulation, or any ruling, writ, injunction, order, judgment or decree
      of any court, administrative agency or other governmental body applicable
      to it, or any of its properties or assets, (ii) conflict with or result in
      any breach of any of the terms, conditions or provisions of, or constitute
      (with due notice or lapse of time, or both) a default under, or result in

      under, any contract to which it is a party or (iii) violate its
      certificate of incorporation or by-laws or other organizational documents,
      that in the case of clause (i) or (ii), would individually or in the

      prevent the consummation of the transactions contemplated hereby. Without
      limiting the generality of the foregoing, S-P represents and warrants that
      neither it nor any of its Affiliates has any obligation to any Third Party

      simvastatin or [***] for combination use so that such Third Party could

      and (ii) for animal health uses pursuant to a joint venture with Aventis
      S.A.

      Section 8.2. Certain Representations.

            (a)-(d)      [***]


















            (e) S-P hereby represents and warrants that the Cholesterol
      Assignment Documents, together with this Agreement and the Related
      Agreements, provide to the Singapore Partnership all of the rights and
      obligations and all of the benefits of all of the representations,
      warranties, covenants and agreements provided to Schering Sales
      Management, Inc. pursuant to the Schering


                                      -38-

      License Agreement (Existing Cholesterol Combination IP), dated as of the
      date hereof and as may be amended from time to time, excluding only the
      obligations under Section 7 thereof.

      Section 8.3. Certain Covenants. Each party hereto, with respect to itself,
agrees that, for so long as this Agreement is in effect:

            (a) Maintenance of Corporate Existence, etc. Such party shall
      maintain in full force and effect its corporate existence, rights,
      governmental approvals, permits, and franchises and all licenses and other
      rights material to and necessary in the conduct of its business as
      currently conducted and as proposed to be conducted, except to the extent
      that such failure to preserve and maintain such existence and
      qualifications would not reasonably be expected to have a Material Adverse
      Effect.

            (b) Compliance with Laws. Each Company shall use reasonable efforts
      to comply with all applicable laws, rules regulations and orders, except
      for violations or failures to so comply, if any, that, individually or in
      the aggregate, would not reasonably be expected to have a Material Adverse
      Effect. Each M Member and each S-P Member shall comply with all applicable
      laws, rules, regulations and orders as it relates to such party with
      respect to the Cholesterol Business, except for violations or failures to
      so comply, if any, that, individually or in the aggregate, would not
      reasonably be expected to have a Material Adverse Effect.

            (c) Insurance. The Companies shall maintain adequate insurance
      covering all aspects of the Cholesterol Businesses. Each other party shall
      keep its assets that are necessary to perform its obligations under this
      Agreement and the Related Agreements and which are of an insurable
      character, if any, insured in accordance with such party's then applicable
      insurance program for its business.

      Section 8.4. Certain Obligations. Each of M and S-P hereby guarantees the
performance by their respective Affiliates of each of such Affiliates'
obligations as members or partners of the Companies and/or as parties to the
Related Agreements. Each of M and S-P agrees that the Members that are their
respective Affiliates shall not engage in any business other than the ownership
of the Interests and matters incidental thereto.

      Section 8.5. Indemnification.

            (a) General Indemnification. Each party hereto shall indemnify,
      defend and hold the other parties, their affiliates, their respective
      officers, directors, partners, members, shareholders, employees, agents,
      representatives, successors and assigns (each an "Indemnified Entity")
      harmless from and against all Losses (as defined in Section 8.5(b))
      incurred or suffered by an Indemnified Entity arising or resulting from
      the breach of any of the representations, warranties or covenants


                                      -39-

      made by any party in Sections 8.1, 8.2, 8.3 and 8.4. Notwithstanding any
      provision to the contrary contained in this Agreement, none of Indemnified
      Entities shall make any claim against either party, as the case may be,
      for any breach of representation and warranty until the dollar amount of
      all such claims shall exceed in the aggregate the amount of $2,000,000.

            (b) Indemnification Principles. For purposes of this Section 8.5,
      "Losses" shall mean each and all of the following items: claims, losses
      (other than lost profits), liabilities, obligations, payments, damages
      (other than punitive, special, indirect, consequential, incidental,
      exemplary or other similar damages), charges, judgments, fines, penalties,
      amounts paid in settlement, costs and expenses (including, without
      limitation, interest which may be imposed in connection therewith, costs
      and expenses of investigation, actions, suits, proceedings, demands,
      assessments and reasonable fees, expenses and disbursements of counsel,
      consultants and other experts).

            (c) Claim Notice. A party seeking indemnification under this Section
      8.5 shall, promptly upon becoming aware of the facts indicating that a
      claim for indemnification may be warranted, give to the party from whom
      indemnification is being sought a claim notice relating to such Loss (a
      "Claim Notice"). Each Claim Notice shall specify the nature of the claim,
      the applicable provisions of this Agreement under which the claim for
      indemnity arises, and, if possible, the amount or the estimated amount
      thereof. No failure or delay in giving a Claim Notice and no failure to
      include any specific information relating to the claim (such as the amount
      or estimated amount thereof) or any reference to any provision of this
      Agreement or other instrument under which the claim arises shall affect
      the obligation of the party from whom indemnity is sought except to the
      extent such party is materially prejudiced by such failure or delay.

            (d) Related Agreements. Notwithstanding the foregoing, to the extent
      there is any conflict between the indemnification provisions in this
      Agreement and any Related Agreement, the indemnification provisions in the
      Related Agreements shall control and preempt this Section 8.5, but only
      with respect to the applicable Related Agreement.

                                   ARTICLE IX

                                  MISCELLANEOUS

      Section 9.1. Confidentiality.

            (a) Without limiting the effect of the confidentiality provisions of
      any of the Related Agreements, and subject to the exceptions provided in
      Section 9.1(b), neither S-P or M nor their respective Affiliates nor any
      Company shall, without the prior written consent of S-P or M, as the case
      may be, divulge, use or


                                      -40-

      permit its, or its Affiliates', officers, employees, agents, advisors or
      contractors to divulge to any Person or use (other than as provided in
      Section 9.1(c)):

                  (i) the contents of this Agreement or any of the Related
            Agreements;

                  (ii) any confidential or proprietary information which has
            been provided to it (whether before or after the date of this
            Agreement) by any of the other parties hereto; or

                  (iii) any confidential or proprietary information relating to
            the Cholesterol Business other than the information covered by
            Section 9.1(a)(ii);

      including, in each case, all financial, marketing and technical
      information, specifications, ideas, concepts, technology, processes,
      knowledge and know-how, together with all details of customers, suppliers,
      prices, discounts, margins, information relating to research and
      development, current trading performance and future business strategy
      (collectively, the "Confidential Information").

            (b) The restrictions imposed by Section 9.1(a) shall not apply to
      the disclosure of any information which:

                  (i) is or becomes generally available to the public other than
            as a result of any breach of the provisions of this Agreement;

                  (ii) is lawfully in the possession of such other party prior
            to receipt from the disclosing party;

                  (iii) is commonly known to Persons engaged in the
            pharmaceutical industry other than as a result of any breach of the
            provisions of this Agreement;

                  (iv) is independently developed by such party without
            reference to the other party's or the Companies' Confidential
            Information; or

                  (v) is required to be disclosed by S-P, M or any Member or any
            Company under any law applicable to the conduct of such party's
            business or otherwise or is disclosed upon S-P, M or any Member or
            any Company becoming legally compelled to disclose, if, in any such
            case, S-P, M or any Member or any Company under such legal
            obligation or compulsion has used its best efforts to afford the
            other party the opportunity to obtain an appropriate protective
            order or other satisfactory assurance of confidential treatment for
            the information required to be so disclosed.

            (c) Each of S-P, M and the Members shall ensure that Confidential
      Information is disclosed only to those of its and its Affiliate's
      officers, employees, agents, advisors and contractors who need to know it,
      and who are bound by


                                      -41-


      written obligations of confidentiality in respect of such information or
      have similar duties under their professional ethics code, and each party
      hereto takes full responsibility for all actions of its employees and
      advisors and those of its Affiliates.

            (d) Each of S-P, M and the Members will return all copies of
      documents containing Confidential Information to the party to which such
      information relates upon request after termination hereof other than one
      copy which may be maintained solely for record keeping purposes.

            (e) Notwithstanding any other provision of this Agreement, during
      the six-year period following termination of this Agreement pursuant to
      Section 7.2(d), all Confidential Information relating to the Cholesterol
      Products known to, or in the possession of, the Terminated Party and
      entities that were Affiliates of the Terminated Party prior to the
      termination of this Agreement, shall not be disclosed, provided or
      otherwise made available, to the Person that acquired the Terminated Party
      or to any of such Person's Affiliates, officers, directors, employees or
      agents.

      Section 9.2. Publicity. (a) Neither S-P nor any of its Affiliates on the
one hand nor M or any of its Affiliates on the other hand may use the name of
the other or any of the Companies in any publicity or advertising except as
specifically provided in any Related Agreements, and may not issue a press
release or otherwise publicize or disclose any information related to the
existence of this Agreement or any of the Related Agreements or the terms or
conditions hereof or thereof without the prior written consent of the other. S-P
and M shall agree on the form, content and timing of the initial press release
or public statement that may be used by either of S-P or M to describe this
Agreement and any of the Related Agreements and any subsequent press release or
subsequent public statement with respect to or relating to the transactions
contemplated by this Agreement or any of the Related Agreements or any of the
terms or conditions hereof or thereof. In the event that either S-P or any of
its Affiliates on the one hand or M or any of its Affiliates on the other hand
(the "Disclosing Party") is requested (by oral questions, interrogatories,
requests for information or documents in legal proceedings, subpoena, civil
investigative demand or other similar process) or required (by applicable
federal or state securities laws or any rule or regulation of any national
securities exchange) to make any such disclosure, the Disclosing Party shall
provide the other party (either S-P or M, as the case may be) with prompt
written notice of any such request or requirement so that such other party may
seek a protective order or other appropriate remedy and/or, if it also
determines that such disclosure is required, waive compliance with the
provisions of this Section 9.2. If, in the absence of a protective order or
other remedy or the receipt of a waiver by such other party, the Disclosing
Party is nonetheless, in the written opinion of its outside legal counsel,
legally compelled to make such disclosure, the Disclosing Party may disclose
only that portion which such counsel advises the Disclosing Party is legally
required to be disclosed, provided that the Disclosing Party shall use its best
efforts to avoid such disclosure including, without


                                      -42-

limitation, by cooperating with the other party to obtain an appropriate
protective order or other reliable assurance that, to the extent available,
confidential treatment will be afforded to such information included in the
disclosure.

            (b) None of the Companies may use the name of either M or S-P or
their respective Affiliates in any publicity, press release, or other similar
public disclosure without the prior written consent of M or S-P, as the case may
be.

      Section 9.3. Further Assurances. Each of S-P and the S-P Members on the
one hand and M and the M Members on the other hand shall cooperate with each
other and shall promptly execute, acknowledge and deliver any assurances,
approvals or documents reasonably requested by the other that is necessary for
the requesting party to satisfy its obligations hereunder or obtain the benefits
contemplated hereby.

      Section 9.4. Notices. All consents or other notices provided for in this
Agreement shall be in writing, duly signed by the party giving such notice, and
shall be delivered, telecopied or mailed by registered or certified mail, as set
forth on Schedule 9.4. Notices delivered to an addressee shall be deemed to have
been given upon such delivery. Notices sent by telecopier shall be deemed to
have been given upon confirmation by telecopy answerback (followed promptly by
the mailing of the original of such notice). Notices mailed by registered or
certified mail shall be deemed to have been given upon the expiration of five
(5) business days after such notice has been deposited in the mail.

      Section 9.5. Failure to Pursue Remedies. The failure of any party to seek
redress for violation of, or to insist upon the strict performance of, any
provision of either this Agreement or any Related Agreement shall not prevent a
subsequent act, which would have originally constituted a violation from having
the effect of an original violation. No waiver of any breach of any of the terms
of this Agreement or any of the Related Agreements shall be effective unless
such waiver is in writing and signed by the party or parties against whom such
waiver is claimed.

      Section 9.6. Cumulative Remedies. The rights and remedies provided by this
Agreement are cumulative and the use of any one right or remedy by any party
shall not preclude, constitute an election of remedies or waive its right to use
any or all other remedies. Said rights and remedies are given in addition to any
other rights the parties may have by law, statute, ordinance or otherwise.

      Section 9.7. Assignment; Binding Effect. Except as specifically set forth
in the Related Agreements, without the consent of all of the parties hereto,
which consent may be given or withheld by each party in its sole discretion,
neither this Agreement nor any Interest of a party in any of the Companies may
be assigned or otherwise transferred, except (i) to wholly-owned subsidiaries of
such party provided that any such subsidiary remains at all times directly or
indirectly wholly-owned by M or S-P, as the case may be or (ii) pursuant to
Section 7.3. Subject to the foregoing, this Agreement shall be binding


                                      -43-

upon and inure to the benefit of the parties hereto and, to the extent permitted
by this Agreement, their successors, legal representatives and permitted
assigns.

      Section 9.8. Severability. In the event of any challenge of the validity
or enforceability of any term, part or provision of this Agreement or any of the
Related Agreements, until a final, unappealable decision is rendered and,
pending such final, unappealable decision, such challenged term, part or
provision shall remain in full force and effect. Any term, part or provision of
this Agreement or any of the Related Agreements, which is determined by a court
in a final, unappealable decision to be invalid or unenforceable in any
jurisdiction shall, as to that jurisdiction, be ineffective to the extent of
such invalidity or unenforceability without rendering in any way invalid or
unenforceable the remaining terms, parts and provisions of this Agreement, or
any of the Related Agreements or affecting the validity or enforceability of any
of the terms, parts or provisions of this Agreement or any of the Related
Agreements, in any other jurisdiction and, accordingly, all such other terms,
parts and provisions shall remain in full force and effect. If any provision of
this Agreement or any of the Related Agreements, is so broad as to be
unenforceable, the provision shall be interpreted to be only so broad as is
enforceable.

      Section 9.9. Standstill.

      (a) Each of S-P and M agrees and acknowledges that, for the Standstill
Period, it and its affiliates (as currently defined in Rule 12b-2 under the
Exchange Act and as defined under current law interpreting Rule 12b-2) will not,

arrange financing to or for others or encourage others to), directly or
indirectly, acting alone or in concert with others, unless specifically
requested in writing in advance by the Board of Directors of the other party:

      permission to do so), ownership (including, but not limited to, beneficial
      ownership as defined in Rule 13d-3 under the Exchange Act) of any of the
      assets or businesses of the other party or any securities issued by the
      other party, or any rights or options to acquire such ownership (including
      from a Third Party), other than de minimus acquisitions of securities
      which are disposed of in the public market promptly,

            (ii) seek or propose to influence or control (publicly or otherwise)
      the management or the policies of the other party or to obtain
      representation on the other party's Board of Directors, or "solicit," or
      participate in any "solicitation" of, any "proxies" or "consents" (as such
      terms are defined in Regulation 14A under the Exchange Act) with respect
      to any securities of the other party,

            (iii) enter into any discussions, negotiations, arrangements or
      understandings with any third party with respect to any of the provisions
      of this Section 9.9,


                                      -44-

            (iv) seek to amend, modify or supplement this Section 9.9 or seek to
      have the other party or its Affiliates waive or relinquish any of the
      restrictions of this Section 9.9,

            (v) seek or request permission to do any of the foregoing or make or
      seek permission to make any public announcement with respect to any of the
      provisions of this Section 9.9, or

            (vi) take any action which would result in or would reasonably be
      expected to result in the other party making a public announcement
      regarding any of the provisions of this Section 9.9.

      (b) Notwithstanding the provisions of Section 9.9(a), in the event that
the Board of Directors of M or S-P resolves to engage in, or engages in, a
process designed for such party to solicit offers relating to transactions
which, if consummated, would constitute (i) a Business Combination involving a
sale of all or substantially all the Outstanding Voting Securities of M or S-P,
as the case may be, for consideration consisting of at least 80% cash and/or
non-voting securities, or (ii) a Business Combination that directly results in a
shift of direct and indirect majority voting control from the public
shareholders of M or S-P, as the case may be, to a single shareholder or "group"
of shareholders (as defined in Regulation 13D), then the provisions of Section
9.9(a) shall be deemed to be waived solely to the extent necessary to permit the
other party to participate in such process on terms and conditions at least as
favorable to such other party as those offered to the other participants in such
process until such time, if any, as the Board of Directors of M or S-P, as the
case may be, terminates, rescinds or allows such process to lapse.

      Section 9.10. Counterparts. This Agreement may be executed in any number
of counterparts with the same effect as if all parties hereto had signed the
same document. All counterparts shall be construed together and shall constitute
one instrument.

      Section 9.11. Integration. This Agreement and the Related Agreements
constitute the entire agreement among the parties hereto pertaining to the
subject matter hereof and thereof and supersede all prior agreements and
understandings pertaining thereto. In the event of any inconsistency between the
terms and conditions of this Agreement and the terms and conditions of any of
the Related Agreements, the terms and conditions of this Agreement shall
prevail, except as specifically provided herein.

      Section 9.12. Governing Law. This Agreement and the rights of the parties
hereunder shall be interpreted in accordance with the laws of the State of
Delaware, and all rights and remedies shall be governed by such laws without
regard to principles of conflict of laws.

      Section 9.13. Amendments. Any amendment, supplement or waiver to this
Agreement shall be made in writing and shall be adopted and be effective only if
signed and approved by each of the parties hereto.

      Section 9.14. Judicial Proceeding.

            (a) General. Any disputes, claims, controversies or disagreements
      with respect to this Agreement or any of the Related Agreements, including
      whether a Material Breach has occurred, that cannot be resolved pursuant
      to the procedures set forth in Sections 3.3(e), 3.6(b) and 7.1, such
      procedures to be fully complied with, as applicable, shall be finally
      determined in a judicial proceeding; provided that (i) no party shall seek
      dissolution by a judicial forum or by operation of law, appointment of a
      trustee, receiver, custodian or similar person, including, without
      limitation, pursuant to Section 86.491 of the Nevada Limited Liability
      Company Act and Section 18-802 of the Delaware Limited Liability Company
      Act and (ii) the foregoing shall not limit any remedies specifically
      provided in any of the Related Agreements. Notwithstanding anything to the
      contrary, no dispute relating solely to business decisions relating to the
      operation of the Cholesterol Business shall be submitted to any judicial
      proceeding hereunder.

            (b) Consent to Jurisdiction. Each party to this Agreement, or to any
      of the Related Agreements hereby, consents to the exclusive jurisdiction
      of the state courts of New York for the purposes of any action or
      proceeding arising out of or in connection with this Agreement or any of
      the Related Agreements pursuant to Section 9.14(a), and each of the
      parties hereto irrevocably agrees that all claims in respect to such
      action or proceeding may be heard and determined exclusively in the New
      York Supreme Court-Commercial Division. None of the parties to this
      Agreement, nor any of their subsidiaries or Affiliates, will raise any
      objection to proceedings in New York based on section 1312 of the New York
      Corporation Law or any similar statute. Each of the parties hereto agrees
      that a final judgment in any action or proceeding shall be conclusive and
      may be enforced in other jurisdictions by suit on the judgment or in any
      other manner provided by law. Each of the parties hereto further
      irrevocably consents to the service of any summons and complaint and any
      other process in any other action or proceeding relating to this Agreement
      or any of the Related Agreements, on behalf of itself or its property, by
      the personal delivery of copies of such process to such party. Nothing in
      this Section 9.14(b) shall affect the right of any party hereto to serve
      legal process in any other manner permitted by law.

      Section 9.15. Enforcement of Certain Rights. In the event that M or S-P
believes that the other party or an Affiliate of the other party is not
complying with its obligations as a whole in a material respect, under any of
the Related Agreements, any dispute with respect thereto shall be referred to
the applicable Board and first be subject to resolution pursuant to the
provisions of Section 3.3(e). Notwithstanding anything contained herein, if the
dispute cannot be resolved pursuant to such dispute resolution procedures, then
the complaining party shall have the power and authority to enforce on behalf of
the Company, or to cause the Company to enforce, the Company's rights through a
judicial remedy in accordance with the provisions of Section 9.14 [Judicial
Proceedings]; provided that notwithstanding the foregoing, M shall have the
right to


                                      -46-

immediately seek on behalf of any Company a judicial remedy in the event it
believes that there has been or is reasonably likely to be a breach of any
agreements which require the consent of M for any licensing of ezetimibe to any
party, or that prohibits the licensing of ezetimibe to other parties, or that
any exclusive product rights are being violated or are reasonably likely to be
violated. If one Member or any of its Affiliates agrees to license to a Company
manufacturing technology or know-how pursuant to the terms of a Manufacturing
Agreement (the "Licensor"), then the parties hereto that are Affiliates of the
Licensor shall not take any action (or omit to take any action) which could
materially hinder or frustrate the ability of the Company to enforce and realize
the benefits of such License.

      Section 9.16. No Third Party Beneficiaries. Except as otherwise
specifically set forth in the Related Agreements, neither this Agreement nor any
of the Related Agreements shall confer upon any Person, other than the parties
hereto and thereto, any rights or remedies hereunder or thereunder.

      Section 9.17. Survival. Notwithstanding any other provision herein, if
this Agreement is terminated for any reason, the applicable provisions of
Sections 8.1, 8.2, 8.4, 8.5 and 9.14, and any applicable definitions set forth
in Section 1.2, shall survive to the extent necessary to effectuate any Related
Agreements that survive such termination, and Sections 7.3(f), 7.3(g), 7.3(i)
and 9.9 (together with the applicable definitions set forth in Section 1.2)
shall survive for the periods respectively set forth in each such section.


                                      -47-

      IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
