future dates,  in  other countries  throughout  the world,  including  countries
within  Eastern  Europe,  to  which  the Parties  agree  to  extend  their joint
ventures. While the specific  form of the joint  ventures may vary in  different
countries,  it is the intention of the parties, by this Agreement, to agree upon
certain principles which will govern the management and strategic development of
the joint ventures as agreed and implemented by the Parties.

        Article  VI) or divestitures  by any JV  Entity, or a  series of related
        divestitures which taken together would be material, it being understood
        that the divestiture of any single product brand in any country shall be
        deemed material;
 
             (B) material  transactions, or  a  series of  related  transactions
        which taken together would be material, between any JV Entity and either
        Party  or  their  Affiliates,  other  than  a  transaction  described in

        OTC Zovirax  or any  OTC Switch  Product as  to which  Wellcome was  the
        Originating Party;
 
             (D)  admission to  any JV  Entity of any  Person other  than W-L or
        Wellcome  or  any  of  their  wholly  owned  (directly  or   indirectly)
        Affiliates;
 
             (E)  the issuance  of any  equity interest  in a  JV Entity  to any
        Person (other than qualifying shares required by local law to be held by
        a member of the Governing Board of a JV Entity);
 
                                       9
 

             (F) any  act to  dissolve any  JV  Entity or  to terminate  any  JV
        Business other than pursuant to Article XIV hereof;
 
             (G)  the dismissal or appointment  of a Certified Public Accountant
        or auditor with respect to a JV Entity or a change in Fiscal Year for  a
        JV Entity; and
 
             (H)  any amendment to the memorandum  or articles of association or
        similar constituent document of a  JV Entity, or any material  amendment
        to an Operative Document to which a JV Entity is a party.
 
     For  purposes of subparagraphs  (A) and (B)  of this clause  (i) only those
acquisitions, divestitures or transactions (other than a divestiture  (including
out licenses) of a single product brand as set forth in subparagraph (A) of this
Section  3.02(b)(i)) involving a  purchase price, or,  in the case  of a license
transaction, payments other than those calculated on the basis of product  sales
(e.g.,  up-front fees and milestone  payments), in excess of  5% of Net Sales of
the relevant JV Entity for the preceding Fiscal Year shall be deemed material.
 
          (ii) Subject to local law and  clause (i) above, each Governing  Board
     by simple majority vote shall have the power to, among other things:
 
             (A)  approve the nomination  by W-L of the  General Manager and the
        chief financial officer of each JV Entity for the purpose of  conducting
        the day-to-day operations of such JV Entity;
 
             (B)  subject to Section 3.02(b)(i)(C), approve the Annual Operating
        Plan and  Strategic Plan  or any  amendment thereto  of a  JV Entity  as
        proposed by JV Management;
 
             (C)  consistent  with  Section  3.08,  approve  all  proposals  for
        financing of the operations of such JV Entity;
 
             (D) consistent  with Section  4.02(b), approve  the making  of  any

        Manufacturing  and Supply Agreement or Wellcome Manufacturing and Supply
        Agreement), reliance  on another  JV  Entity's regulatory  licenses  and
        other sales, marketing and regulatory issues.
 
     (c) No JV Entity shall be charged for any expense based on the depreciation
of  a capital expenditure (within the meaning of  U.S. GAAP or U.K. GAAP, as the
case may be) relating  to the JV Business  which capital expenditure shall  have
been  incurred  with  respect to  a  project  or a  series  of  related projects
commenced by either  Party after the  date of this  Agreement which  expenditure
exceeds $5 million unless such expenditure has been approved by the other Party.
For  the avoidance of doubt, any capital expenditures in respect of a project or
a series of related projects commenced prior to the date hereof shall be  deemed
approved by the other Party.
 
     SECTION  3.03. Quorum; Notice; Meetings. The governing documents of each JV
Entity shall require, subject to local  law, the personal presence of not  fewer
than  three representatives including at  least one representative designated by
Wellcome and two representatives  designated by W-L to  constitute a quorum  for
the  transaction of business at  any meeting of the  Governing Board for such JV
Entity. In addition,  any representative may  call a meeting  of such  Governing
Board,  and  written notice  specifying  any matters  to  be considered  at such
meeting and accompanied by supporting documentation (which notice may be  waived
by  any  representative  representing  the  other  Party  consenting  thereto in
writing), shall be given to all representatives at least ten Business Days prior
to such  meeting or  such longer  period  as may  be required  by law.  For  all
purposes,  subject  to  local  law, each  representative  shall  have  one vote.
Meetings of each Governing  Board shall be  held not less  often than once  each
Fiscal  Quarter. Each Party shall use reasonable efforts to ensure the existence
of a quorum at any duly convened meeting of a Governing Board and that no  other
steps  are  taken  which  might  reasonably be  expected  to  impede  the proper
management of any JV Entity.
 
     SECTION   3.04.   Designation   of   New   Representatives   or   Alternate
Representatives. Any Party may at any time, by written notice to the other Party
and to the relevant Governing Board of any JV Entity,
 
                                       10
 

remove  (with or without cause) one or  more of its representatives or alternate
representatives on any such Governing Board and designate new representatives or
alternate representatives. No representative or alternate representative may  be
removed except by the Party designating the same.
 
     SECTION 3.05. Other Positions of Representatives. Any Person may act in one
or  more of the capacities of representative or alternate representative, member
of any committee or officer, director, manager  or employee of any JV Entity  or
any Party, notwithstanding that such Person acts in any other such capacity.
 
     SECTION 3.06. Annual Operating Plans; Incentive Compensation Plans; Initial
Plans; Plan Compliance. (a) The General Manager of each JV Entity shall cause to
be  submitted  to the  Governing Board  of each  JV Entity,  (i) not  later than
December 1 in each year or such date as may be otherwise agreed by the Governing
Board, for  review and  approval, an  annual operating  plan for  the  following
Fiscal  Year including, among other things, projections and budgets with respect
to  Cost  of  Goods   Sold,  sales,  operating   income,  cash  flows,   capital
expenditures, financing, developing and marketing activities for the relevant JV
Business  and integrating each  product line therein  (each an 'Annual Operating
Plan') and (ii) not  later than April  1 in each year,  for a three-year  period
commencing  with the following Fiscal Year,  a strategic plan covering strategic
business issues to be addressed for  such period (each a 'Strategic Plan',  with
the  Annual Operating Plan and the Strategic Plan being hereinafter collectively
referred to as the 'Plans').  Notwithstanding the foregoing, the initial  Annual
Operating  Plan  and Strategic  Plan,  respectively, for  a  JV Entity  shall be
prepared and  submitted to  the  Governing Board  within  three months  and  six
months,  respectively, following the  Closing of the  relevant JV Implementation
Agreement.   Notwithstanding  Section  3.02(b)(i)(C)  and  subject  to   Section
10.01(b),  in the  event of a  disagreement between  W-L and Wellcome  as to any
aspect of the Plans  for any period affecting  the supply, development, sale  or
marketing  of JV Prescription Zovirax in the Remainder of the World, OTC Zovirax
or any OTC Switch Product as to  which Wellcome was the Originating Party,  only
those  provisions of such Plans  as shall have been  approved or proposed by the
representatives of Wellcome  on the Governing  Board of the  relevant JV  Entity
shall be implemented.
 
     (b)  Notwithstanding anything in this Agreement to the contrary (including,
without limitation, Sections  3.06(a) and  5.04), no Plan  or component  thereof
shall  be  approved or  implemented which  unreasonably discriminates  among the
following product categories: (i) products resulting from the Glaxo Arrangement,
(ii) OTC Zovirax and JV Prescription Zovirax, (iii) OTC Switch Products and (iv)
all other products included in the respective Contributed Businesses or acquired
or developed by the relevant JV Entity subsequent to the date hereof.
 
     (c)  With  respect  to  each  JV  Entity,  there  shall  be  an   incentive
compensation  plan for all management employees whose principal responsibilities
relate to  operations  of such  JV  Entity. Such  plan  shall be  based  on  the
performance  of the JV Entity and shall  set forth, among other things, monetary
incentives for such employees for the purpose of increasing the productivity and
profitability of such JV Entity.
 
     (d) The provisions of the first  such Strategic and Annual Operating  Plans
insofar  as they  relate to  OTC Zovirax  shall be  prepared by  the relevant JV
Entity and insofar as they  relate to JV Prescription  Zovirax or an OTC  Switch
Product  of which Wellcome is the Originating  Party shall be prepared by or for
Wellcome.
 
     (e) Where any  obligation in this  Agreement or any  Operative Document  is
expressed to be of an Affiliate of W-L or Wellcome, then W-L or Wellcome, as the
case may be, shall assure that such Affiliate complies with such obligation and,
in  the case of financial obligations, hereby  guarantees to the other Party the
performance thereof (or,  in lieu  of its  guarantee, Wellcome  may procure  the
guarantee  of  The  Wellcome  Foundation Limited).  Each  Party  shall  take all
reasonable steps to ensure, insofar as it is able, that each JV Entity  complies
with all approved Plans and Operative Documents, including this Agreement.
 
     SECTION  3.07.  No Remuneration.  Unless  the Parties  otherwise  agree, no
Person shall be entitled to any fee, remuneration or compensation in  connection
with  their service as a representative, alternate representative or as a member
of any committee of the Governing Board.
 
                                       11
 

     SECTION 3.08. Funding. (a) W-L and Wellcome hereby agree to make  available
such  funds or  other property  as may be  agreed upon  to be  necessary for the
conduct of the JV Business by each JV Entity in accordance with the relevant  JV
Implementation Agreement and sound commercial principles.
 
     (b)  No JV Entity  shall incur or  suffer to exist  any Indebtedness except
borrowings to  finance net  working  capital needs  as  contemplated by  the  JV
Entity's  Annual  Operating  Plan,  or  borrowings  in  accordance  with Section
4.02(b). Such financing needs may be changed from time to time as agreed by  the
Parties.  In the case  of the U.S.  Partnership, to the  extent practicable, W-L
shall make  such  Indebtedness available  as  loans bearing  interest  at  W-L's
commercial  paper rate. In the  case of the JV Entities  in the EC Territory and
the Other  European Territory,  W-L  and Wellcome  will make  such  Indebtedness
available  through  appropriate  bank  facilities.  In  the  case  of  all other
countries, to  the  extent  practicable,  the  Party  making  treasury  services
available  shall make such  Indebtedness available as  loans bearing interest at
the rate incurred by the Party in  respect of short-term debt in the country  in
which  the  JV  Entity operates.  In  the event  either  Party is  able  to make
Indebtedness available at a lower rate than that offered by the other Party,  it
shall have the right to do so.
 
     (c)  The incurrence  of a  Loss by  a JV  Entity for  any period  shall not
require any capital or other contribution by a Party to such a JV Entity, unless
required by local law or the relevant JV Implementation Agreement.
 
     SECTION  3.09.  Governance;  Percentage   Interest  of  Wellcome  in   U.S.
Partnership.  If Wellcome's share of the  Profits (including Wellcome's share of
Glaxo Profits and Losses) of the U.S.  Partnership equals or exceeds 50% of  the
total  Profits (including all Glaxo Profits  and Losses) of the U.S. Partnership
over a period consisting of eight consecutive Fiscal Quarters, Wellcome may give
written notice to W-L within 90 days after the end of such eighth Fiscal Quarter
that it wishes to renegotiate the  provisions for governance of the JV  Entities
as  set forth herein. Following  receipt of such notice,  W-L and Wellcome shall
negotiate in good faith for a period  of up to 60 days an appropriate  amendment
to  the provisions of this Article III to  permit a greater role for Wellcome in
the governance of the  JV Entities. If  the Parties are  unable to agree  within
such  60-day period, Wellcome shall have (as  its exclusive remedy) the right to
exercise the remedies contained in Sections  14.04(a)(i) and (ii), as applicable
(treating the U.S. Partnership and all JV Entities in the Remainder of the World
as Affected JV Entities), using the time periods set forth therein and as if any
period specified for the cure of dissatisfaction had expired.
 
     SECTION 3.10. Expenses of JV Entities; Adjustments. (a) In connection  with
products  and  services  to  be  supplied  pursuant  to  the  various  Operative
Documents, each of the JV  Entities shall be charged  with the items of  expense
identified  as items one  through ten of  Schedule 1 hereto  (as those items are
more fully  explained  in  said  Schedule and  the  relevant  JV  Implementation
Agreements and the Operative Documents relating thereto).
 
     (b)  Except as provided in  Section 6.03(b), to the  extent that a Party or
any of its Affiliates provides products, services,  or the use of property to  a
JV  Entity or makes charges at a price that includes (i) in the case of products
or services,  a  mark-up over  the  Fully Allocated  Cost  of such  products  or
services,  (ii)  royalties (other  than  third-party royalties  and  the royalty
payable to  Wellcome pursuant  to  Section 4.04  hereof)  or lease  payments  in
respect  of the use of property in excess  of Fully Allocated Cost, or (iii) any
other charge  in excess  of the  Fully Allocated  Cost thereof,  the  respective
interests  of the Parties in  the Profits and Losses of  such JV Entity shall be
adjusted in such manner that, when combined with such mark-ups, royalties, lease
payments, or other charges in excess  of Fully Allocated Cost, the total  amount
received  by and allocated to each Party  in excess of Fully Allocated Cost (the
'Actual Allocation') shall  conform to the  allocation principles prescribed  in
Section  4.02 (the 'Prescribed Allocation'). In  the event the Parties have been
unable to agree within 90 days after the end of any Fiscal Year upon the  amount
of adjustment to conform the Actual Allocation to the Prescribed Allocation, the
Parties shall submit the matter for resolution to an accounting firm selected by
the  then Certified Public Accountants for each Party. The decision of that firm
shall be  binding  upon, and  non-appealable  by,  the Parties.  Based  on  that
decision  (or in the  event the Parties  shall have agreed,  their decision) the
Parties shall negotiate to determine  the appropriate method of adjustment  and,
failing  agreement,  within 30  days the  Party  that has  received or  has been
allocated an amount  greater than it  should have received  or should have  been
allocated (the 'Adjusting Party') shall pay to the
 
                                       12
 

appropriate  JV Entity  the excess  of such  Party's Actual  Allocation over the
amount it would have received  under the Prescribed Allocation for  distribution
in  accordance with  Section 4.02  and this Section.  The Parties  agree, to the
extent practicable,  to minimize  and balance  such mark-ups,  royalties,  lease
payments,  and other charges to  minimize variances in any  Fiscal Year from the
allocation principles set forth in Section 4.02 and this Section.
 
     SECTION 3.11.  Deliberations. The  deliberations  of each  Governing  Board
shall  not extend to any  business activity of the Parties  other than as may be
necessary  to  perform  their  responsibilities   in  connection  with  the   JV
Businesses.
 
     SECTION  3.12. Bank Accounts.  To the greatest  extent practicable, each JV
Entity shall keep its funds separate from those of any other Person (other  than
another JV Entity) maintaining its own depositary, banking and similar accounts.
Unless  otherwise agreed  by the  Parties, to  the extent  that funds  of any JV
Entity are held by one of the Parties or an Affiliate as a result of  collection
or  otherwise, such Party or Affiliate shall pay over the funds to the JV Entity
within 5 Business Days of  receipt and shall pay to  such JV Entity interest  on
such  funds beginning the date following receipt by such Party or Affiliate. The
rate paid will be an appropriate and equitable publicly available rate for short
term investments in  the relevant currency  in the respective  country which  is
agreed to by the JV Entity and the Parties. In the United States, the rate to be
used  will be the Goldman  Sachs 30 Day Commercial Paper  Index in effect on the
days the funds are held.
 
                                   ARTICLE IV
                            OPERATIONS; JV ENTITIES
 
     SECTION 4.01. General. The JV Business shall be conducted by JV Entities to
be established  from  time  to time  by  the  Parties in  accordance  with  this
Agreement and the relevant JV Implementation Agreements and Operative Documents.
 
     SECTION  4.02. Form and Structure of  JV Entities. The Parties hereto agree
that:
 
          (a) The JV  Entity which will  conduct the JV  Business in the  United
     States  will be the U.S. Partnership, in the  EC Territory and in the Other
     European Territory  it  is intended  that  the  JV Entities  will  be  held
     principally  through a U.K. holding company and it is intended that such JV
     Entities and holding company will where possible under local law be capable
     on the relevant Closing Date of being classified as partnerships for United
     States Federal income tax purposes, in Canada will be a partnership and  in
     Australia  will be a corporation, and the nature of the entity constituting
     each JV Entity in the Non-Core Territory shall be determined by the Parties
     taking into consideration  relevant tax,  accounting and  legal issues  and
     shall be in accordance with Section 15.04 and the Operative Documents.
 
          (b)  Subject to applicable requirements of law, tax considerations and
     the provisions of  the Operating  Plan, unless otherwise  agreed, the  U.S.
     Partnership  will distribute an  amount equal to  Profits quarterly, and in
     other countries in the Remainder of the World, the relevant JV Entity  will
     distribute or otherwise make available an amount equal to Profits annually,
     all  in accordance with the order of priority and allocation of profits and
     losses set  forth  in  paragraph  (c).  Additional  cash  on  hand  may  be
     distributed  or otherwise made available as  agreed upon by the Parties. In
     the event that  there is insufficient  cash to fully  distribute an  amount
     equal to Profits, such cash may be borrowed if agreed by the Parties or the
     Parties may agree upon an alternative arrangement.
 
          (c)  Profits and Losses  of each JV Entity  shall be allocated between
     the  Parties  in  accordance  with  the  provisions  in  the  relevant   JV
     Implementation  Agreement. The principles (except as may be modified by the
     applicable JV Implementation Agreement) governing such allocation, shall be
     as follows:
 
             (i) Except  to the  extent adjusted  pursuant to  Article V,  Glaxo
        Profits and Losses shall be allocated as follows:
 
                (A) In the United States, 100% to W-L unless and until, pursuant
           to Article V, they shall be allocated 90% to W-L and 10% to Wellcome;
           and
 
                                       13
 

                (B)  In  the Remainder  of  the World,  90%  to W-L  and  10% to
           Wellcome.
 
             (ii) Special Profits and Losses attributable to OTC Zovirax in  the
        United States shall be allocated as follows:
 
                (A)  In the  event an NDA  Approval for OTC  Zovirax is received
           prior to  Zovirax  Patent  Expiration  with  at  least  one  year  of
           Exclusivity  from the Launch Date (which Launch Date must occur prior
           to such Patent Expiration), in any Fiscal Year:
 
                    (1) Special Profits shall be  allocated (x) 75% to  Wellcome
               and  25% to W-L  to the extent  that such Special  Profits do not
               exceed 20% of the Net Sales of OTC Zovirax in the United  States;
               and (y) 66-2/3% to Wellcome and 33-1/3% to W-L to the extent that
               such  Special Profits exceed 20% of  the Net Sales of OTC Zovirax
               in the United States; and
 
                    (2) Special Losses  shall be allocated  75% to Wellcome  and
               25% to W-L.
 
                (B)  In the  event (1)  an NDA Approval  for OTC  Zovirax is not
           received prior to Zovirax Patent Expiration with at least one year of
           Exclusivity from the Launch Date (which Launch Date must occur  prior
           to  such Patent Expiration), or (2)  the Parties agree that there are
           not reasonable  prospects  for the  prospective  Launch Date  of  OTC
           Zovirax  occurring prior to  Zovirax Patent Expiration  with at least
           one year of Exclusivity, as the case may be, either Party may give to
           the other Party written notice within 90 days after the occurrence of
           either of such events that it wishes to commence negotiations of  the
           allocation  set forth in  subparagraph (c)(ii)(A) of  this Section to
           provide for an increased allocation of Special Profits or a decreased
           allocation  of  Special  Losses  to  W-L.  The  determination  of  an
           increased  allocation of Special Profits or a decreased allocation of
           Special Losses  to W-L  shall  be negotiated  with reference  to  the
           extent  to which the  value of OTC  Zovirax has been  impaired by the
           failure (x) to have  obtained such approval  prior to Zovirax  Patent
           Expiration  or (y) to  have enjoyed at least  one year of Exclusivity
           from the Launch  Date, as  the case  may be.  In the  event that  OTC
           Zovirax  is not expected to  be approved in the  United States in the
           foreseeable future  following receipt  of the  aforesaid notice,  the
           Parties  shall renegotiate  an increased allocation  of Base Business
           Profits or  a  decreased  allocation of  Base  Business  Losses  with
           reference  to the extent to which  the projected value of OTC Zovirax
           will be impaired by the failure to be so approved.
 
                (C) In the event the Cost of Goods Sold (excluding  intercompany
           markups)  of the U.S. Partnership for  OTC Zovirax exceeds 25% of Net
           Sales in the United  States of OTC Zovirax  for any Fiscal Year,  the
           Parties  shall negotiate  in good  faith a  different allocation from
           that set forth  in subparagraph  (c)(ii)(A) for that  Fiscal Year  in
           order  to provide  an increased  allocation of  Special Profits  or a
           decreased allocation of Special Losses to W-L for that Fiscal Year.
 
             (iii) Special Profits  and Losses  attributable to  the OTC  Switch
        Products of a JV Entity shall be allocated as follows:
 
                (A)   Special  Profits  shall  be   allocated  (x)  75%  to  the
           Originating Party and 25% to the Non-Originating Party to the  extent
           that  such Special Profits do not exceed  20% of the Net Sales of the
           OTC Switch Product; and (y) 66-2/3% to the Originating Party and  33-
           1/3%  to the Non-Originating Party to the extent such Special Profits
           exceed 20% of the Net Sales of the OTC Switch Product; and
 
                (B) Special Losses  shall be  allocated 75%  to the  Originating
           Party and 25% to the Non-Originating Party.
 
                (C)  Any form of Zovirax  to the extent that  it is changed from
           prescription to non-prescription status (other than a  three-gram-or-
           less  cream formulation in the countries of the Core Territory (other
           than the United States)) will be treated, if Wellcome determines that
           such product is to be marketed as a consumer health care product,  as
           an  OTC Switch  Candidate in the  Remainder of the  World and Special
           Profits and Losses  therefrom shall be  allocated in accordance  with
           subparagraphs    (A)    and   (B)    above,    respectively,   except
 
                                       14
 

           that a cream formulation larger than three grams having an indication
           for use  with cold  sores in  the  Remainder of  the World  shall  be
           contributed  by Wellcome to  the relevant JV  Entity upon change from
           prescription to non-prescription status  and the Special Profits  and
           Losses  attributable thereto shall be allocated 50% to W-L and 50% to
           Wellcome, subject to  the royalty  obligations set  forth in  Section
           4.04 hereof.
 
                (D)  In the event the Cost of Goods Sold (excluding intercompany
           markups) of a JV Entity for an OTC Switch Product exceeds 25% of  Net
           Sales  of the  OTC Switch  Product for  any Fiscal  Year, the Parties
           shall negotiate in good  faith a different  allocation from that  set
           forth  in subparagraph (A) or (B) above for that Fiscal Year in order
           to provide an increased allocation of Special Profits or a  decreased
           allocation  of Special Losses  to the Non-Originating  Party for that
           Fiscal Year.
 
             (iv) Base Business Profits and Losses  of the JV Entities shall  be
        allocated to the Parties as follows:
 
                (A)  In the case of the  U.S. Partnership, Base Business Profits
           and Losses shall be allocated 67%  to W-L and 33% to Wellcome  during
           the two-year period ending on the day prior to the second anniversary
           of  the  Closing  Date  for  the  U.S.  JV  Implementation Agreement.
           Thereafter, Base Business Profits and  Losses shall be allocated  70%
           to W-L and 30% to Wellcome.
 
                (B) In the case of the JV Entities in the other countries in the
           Core  Territory, Base Business Profits  and Losses shall be allocated
           50% to  W-L  and  50%  to  Wellcome.  W-L  shall  have,  directly  or
           indirectly, 51% of the voting power and Wellcome shall have, directly
           or indirectly, 49% of the voting power of each such JV Entity.
 
                (C)  Subject to Section 4.03, in the  case of JV Entities in the
           Remainder of the World, excluding  those in the Core Territory,  Base
           Business  Profits and Losses shall be allocated 50% to W-L and 50% to
           Wellcome. W-L shall have 51% of  the voting power and Wellcome  shall
           have 49% of the voting power of each such JV Entity.
 
             (v)  The Export Profit  and Loss realized  by a JV  Entity shall be
        allocated between the  Parties in accordance  with the allocation  ratio
        applicable  to the profit and  loss on such product  in the Territory or
        Territories in which the ultimate sale to a third party takes place.
 
             (vi) The income, gain, deduction or  loss of each JV Entity from  a
        sale, exchange or other disposition of Wellcome Contributed Business, or
        any  portion  thereof,  or  W-L  Contributed  Business,  or  any portion
        thereof, shall be allocated 30% to Wellcome and 70% to W-L to the extent
        that such sale, exchange or other  disposition is of such businesses  in
        the  United States, 50%  to Wellcome and  50% to W-L  to the extent that
        such sale, exchange  or other  disposition is  of such  business in  any
        other country in the Core Territory and shall be allocated in proportion
        to the allocation of Base Business Profits and Losses to the extent that
        such  sale, exchange or  other disposition is of  such businesses in the
        Remainder of  the World  (other than  the Core  Territory). The  income,
        gain, deduction or loss of each JV Entity from a sale, exchange or other
        disposition  of  OTC  Switch  Products shall  be  allocated  75%  to the
        Originating Party  and 25%  to the  Non-Originating Party.  The  income,
        gain, deduction or loss of the U.S. Partnership from a sale, exchange or
        other disposition of OTC Zovirax in the United States shall be allocated
        75%  to Wellcome and 25% to W-L. To  the extent that any interest in the
        Glaxo Arrangement is held by a JV Entity, the income, gain, deduction or
        loss of such  JV Entity from  a sale, exchange  or other disposition  of
        such interest in the Glaxo Arrangement, or any portion thereof, shall be
        allocated  90% to W-L and 10% to Wellcome (unless such profit allocation
        shall have previously been adjusted  pursuant to Article V), other  than
        any  product which  utilizes the Zantac  trademark but  does not contain
        Ranitidine which shall be allocated in accordance with the allocation of
        Base Business Profits  and Losses  set forth in  Section 4.02(c)(iv)  of
        this Agreement.
 
     SECTION  4.03.  Equitable Adjustment.  (a) To  the  extent Closings  in the
countries in the  Core Territory  (other than the  United States)  do not  occur
simultaneously resulting in an inequitable division
 
                                       15
 

of  Profits  and  Losses,  the  Parties agree  to  negotiate  in  good  faith an
appropriate adjustment  to  account  for  such  difference  in  timing  of  such
Closings.
 
     (b) In the event that the profits projected by either Party to be generated
from  the Wellcome Contributed Business and the W-L Contributed Business for any
JV Entity in the Remainder of the  World, excluding the EC Territory, the  Other
European  Territory, Australia and Canada, are  such that an approximately 50-50
profit split with respect to such JV Entity would be inequitable, then upon  the
proposed  formation  of the  relevant JV  Entity, the  Parties shall  attempt to
negotiate an appropriate division  of Base Business Profits  and Losses and  the
relevant  JV Entity shall not  be formed unless and  until such division of Base
Business Profits and Losses is agreed  upon by the Parties. In determining  such
an  appropriate division pursuant  to this Section 4.03,  the Parties shall take
into account such  considerations as may  be deemed to  be relevant,  including,
without  limitation, any Net Sales of OTC Zovirax and JV Prescription Zovirax on
which no royalties were payable pursuant to Section 4.04.
 
     SECTION 4.04. Zovirax Arrangements.  (a) To the  extent that Direct  Profit
Contribution  of OTC Zovirax and JV Prescription Zovirax in the EC Territory and
Other European Territory, collectively, calculated  solely for purposes of  this
clause,  for each of the two twelve-month periods following the Closing Date for
the JV  Implementation  Agreement  for  the  EC  Territory  and  Other  European
Territory,
 
          (i)  is 110% or more than the relevant twelve-month period's Benchmark
     Direct Profit Contribution Target,  50% of the  difference between (x)  the
     actual  amount  of such  Direct  Profit Contribution  and  (y) 110%  of the
     Benchmark  Direct  Profit  Contribution  Target,  shall  be  paid  by   the
     appropriate JV Entity to Wellcome; or
 
          (ii)  is 90% or less than the relevant twelve-month period's Benchmark
     Direct Profit Contribution Target, 50% of the difference between (x) 90% of
     the Benchmark Direct Profit Contribution  Target and (y) the actual  amount
     of  such  Direct Profit  Contribution,  shall be  paid  by Wellcome  to the
     appropriate JV Entity.
 
     The Benchmark Direct Profit Contribution  Target for any Fiscal Year  shall
be  adjusted  to  pro  rate  the  dollar  amount  thereof  over  the  applicable
twelve-month period.
 
     (b) Commencing with each full Fiscal Year following the second twelve-month
period referred to in  paragraph (a), or  any stub period  following the end  of
such twelve-month period until the commencement of the first Fiscal Year, to the
extent that the aggregate Net Sales of OTC Zovirax (including cream formulations
as  to which  Profits and Losses  are allocated 50%  to W-L and  50% to Wellcome
pursuant to  Section 4.02(c)(iii)(C))  and  JV Prescription  Zovirax by  all  JV
Entities  collectively in the Remainder of the World exceed U.S. $125 million in
any Fiscal  Year (pro  rated in  the case  of any  stub period),  as  calculated
pursuant  to the Procedure for Converting  Net Sales, Wellcome shall be entitled
to a royalty of 15% on Net Sales  of OTC Zovirax and JV Prescription Zovirax  in
the  Remainder  of the  World for  any such  Net  Sales in  excess of  U.S. $125
million. The obligation to pay any  such royalty shall be apportioned among  the
various  JV Entities  in such  reasonable manner as  the Parties  may agree. The
aforesaid $125 million sales base shall be changed in each Fiscal Year following
the Fiscal Year in which  OTC Zovirax and JV  Prescription Zovirax sales in  the
Remainder  of the World exceed such amount by a percentage which shall equal the
percentage change in the Nominal Price Index (1985=100), Expenditure on  Medical
Goods  -- Total Pharmaceutical Value in Current Prices (NCV) (or any replacement
index) published by the Organization for Economic Cooperation and Development or
any successor organization after adjusting such index to exclude (to the  extent
practicable)  the component attributable to the United States and any country in
which no JV Entity operates.
 
     (c) In the event of termination in Canada pursuant to Section  14.02(b)(i),
the U.S. $125 million threshold set forth in Section 4.04(a) shall be reduced by
application  of the following formula:  (i) the Net Sales  of OTC Zovirax and JV
Prescription Zovirax in  Canada during  the immediately  preceding Fiscal  Year,
shall  be divided by (ii) the total Net Sales of OTC Zovirax and JV Prescription
Zovirax in the Remainder  of the World during  the immediately preceding  Fiscal
Year  with the  result being  multiplied by  (iii) U.S.  $125 million, provided,
however, that no such reduction shall exceed $25 million.

     SECTION 4.05.  Management  of  JV  Entities. W-L  will  nominate,  and  the
relevant  Governing  Board may  appoint pursuant  to  Section 3.02(b)  hereof, a
General Manager and  a chief financial  officer of each  JV Entity. The  General
Manager  shall have day-to-day  operational responsibility for  the JV Entity to
which his appointment relates.
 
     SECTION  4.06.  Operations  to  be  Conducted  in  Accordance  with  Annual
Operating  Plan and  Direction of the  Relevant Governing  Board. The day-to-day
operations of each JV Entity shall be conducted by the relevant General  Manager
in  accordance with the Annual Operating Plan of such JV Entity and otherwise as
directed by  the relevant  Governing  Board. For  the  avoidance of  doubt,  the
Parties  agree that none of the actions  referred to in Section 3.02(b) shall be
taken by any JV Entity without the  approval of the relevant Governing Board  in
accordance with that Section.
 
     SECTION  4.07. Asset  Contributions. In order  to permit JV  Business to be
conducted by the  JV Entities,  the Parties  have agreed  or will  agree in  the
relevant  JV Implementation Agreements as to  the manner in which certain assets
to be employed  in the JV  Business will be  made available to  the relevant  JV
Entities. For such purposes in respect of a country in the Non-Core Territory or
to  the extent not  previously agreed upon in  respect of a  country in the Core
Territory, the Parties  agree that such  assets shall be  made available on  the
following basis:
 
          (a)  only  those tangible  assets  agreed by  W-L  and Wellcome  to be
     necessary to conduct such JV Business shall be made available;
 
          (b) intellectual property rights shall  be made available pursuant  to
     the  Wellcome  Intellectual  Property Agreement  and  the  W-L Intellectual
     Property Agreement;
 
          (c) to the  extent commercially  practicable, registrations,  licenses
     and  similar  rights from  governmental authorities  relating to  a product
     included in  the  Wellcome  Contributed Business  or  the  W-L  Contributed
     Business,  as the  case may be,  shall be assigned  to a JV  Entity or will
     otherwise be made available to such entity  to permit it to conduct the  JV
     Business  in the relevant Territory subject to  the payment of the costs of
     such transfer  by the  relevant JV  Entity, provided,  however, that  where
     either  Party  or its  Affiliates  makes available  any  such registration,
     license or other similar right, it shall use reasonable efforts to maintain
     the same in full force and  effect subject to compliance in full  therewith
     by  the relevant JV Entity and the payment by the relevant JV Entity of all
     costs relating thereto and the provision of such data and other information
     as may be necessary or required by any authority in order to maintain  such
     status;
 
          (d)  all contracts to the extent a  part of or related to the Wellcome
     or W-L Contributed  Businesses shall  be assigned or  the benefits  thereof
     otherwise made available in accordance with Section 10.08 unless identified
     in an Operative Document as not being assigned or made available; and
 
          (e)  no inventory or  receivables shall be transferred  to a JV Entity
     except to the extent required to minimize tax on the transferring party  in
     connection with the organization of the JV Entity or to satisfy other legal
     requirements,  and  in  any  such  case the  Parties  shall  agree  upon an
     equitable method  by which  the JV  Entity's acquisition  thereof shall  be
     funded, if necessary.
 
     SECTION  4.08.  Management Standards.  Subject  to the  supervision  of the
relevant Governing Board,  W-L will use  its reasonable best  efforts to  assure
that  the administration and  management of each  JV Entity is  carried out in a
competent, professional and timely manner  with reasonable skill and care.  With
respect  to any  Operative Document between  a JV Entity  and W-L or  one of its
Affiliates, any decision made or consent given by or on behalf of the JV  Entity
shall be made or given on an arm's-length basis.

              GLAXO ARRANGEMENT AND WELLCOME PROFIT PARTICIPATION
 
     SECTION  5.01. Treatment  of Glaxo  Arrangement. W-L  has entered  into the
Glaxo Arrangement and  Wellcome shall  determine within  45 days  from the  date
hereof  whether it  objects to  participation in  the Glaxo  Arrangement. In the
absence  of  a  written  objection,  Wellcome  shall  acquire  the  rights   and
obligations  to participate in  the development, marketing  and sale of products
pursuant to the Glaxo
 
                                       17
 

Arrangement, including, without limitation, the payment obligations set forth in
Section 5.02 and  shall participate in  Glaxo Profits and  Losses in  accordance
with  Section 5.03. In the event such written objection is given, Wellcome shall
have no right to participate in the Glaxo Arrangement. Absent such objection  in
respect of the United States, the Glaxo Arrangement will be assigned to the U.S.
Partnership and in all other Territories the Parties' participation in the Glaxo
Arrangement will be in a form and manner to be agreed upon by the Parties.
 
     SECTION  5.02. Payments. (a) Upon the transfer  of the OTC Zantac rights in
the United States  pursuant to Section  5.01(a), Wellcome shall  fund an  amount
equal to 30% of W-L's share of all Glaxo Development Costs incurred prior to NDA
Approval  of OTC Zantac for the development  of OTC Zantac in the United States.
Wellcome shall also be responsible for 30%  of and W-L shall be responsible  for
70%  of the milestone  payments of U.S.  $2.666 million and  U.S. $2.666 million
paid pursuant to the Glaxo  Arrangement by the U.S.  Partnership or W-L, as  the
case  may be,  in connection with  the development  of OTC Zantac  in the United
States pursuant  to  the Glaxo  Arrangement.  Any amounts  payable  by  Wellcome
pursuant  to this Section 5.02 shall be increased to reflect the financing costs
of any payments previously made by W-L  pursuant to the Glaxo Arrangement at  an
assumed  annual interest rate on  such payments from the  date of payment by W-L
through the date of payment  by Wellcome pursuant to  this Section equal to  the
prime  rate charged from  time to time  by Citibank, N.A.  In the event Wellcome
shall so elect pursuant to Section 5.02(b), amounts payable by Wellcome pursuant
to this Section 5.02(a) shall not exceed U.S. $6.5 million.
 
     (b) At such  time as Wellcome  payments pursuant to  Section 5.02(a)  equal
U.S.  $6.5 million,  Wellcome shall have  the right, exercisable  by delivery of
written notice to W-L within 60 days  of its last payment and following  receipt
from  W-L  of  such information  as  shall  be necessary  to  reach  an informed
decision, to renegotiate  Wellcome's liability for  Glaxo Development Costs  and
Wellcome's  participation in Glaxo Profits and Losses attributable to OTC Zantac
in the United States.  Absent the delivery of  written notice of such  election,
Wellcome  shall continue to be  responsible for 30% of  W-L's share of all Glaxo
Development Costs  incurred for  the development  of OTC  Zantac in  the  United
States (including line extensions, other dosage forms and other indications) and
shall be entitled to the allocation of Glaxo Profits and Losses set forth in the
first sentence of Section 5.03(b) hereof.
 
     SECTION   5.03.  Wellcome   Profit  Participation   and  Development  Costs
Obligations. The participation by Wellcome in the Glaxo Arrangement will be upon
the following terms:
 
          (a) With respect to  OTC Zantac in the  United States, all income  tax
     deductions  and credits attributable  to the costs  of development shall be
     allocated to W-L and Wellcome in proportion to their respective funding  of
     such costs as provided in the U.S. Partnership Agreement.
 
          (b)  With respect to OTC  Zantac in the United  States in the event of
     NDA Approval of OTC Zovirax and  NDA Approval of OTC Zantac, Glaxo  Profits
     and  Losses shall thereafter be  allocated 90% to W-L  and 10% to Wellcome;
     provided, however, in the event  Wellcome shall renegotiate, or failing  to
     have  reached  an agreement  within  60 days  of  the commencement  of such
     renegotiation,  elect,  pursuant  to  Section  5.02(b)  to  cap  its  Glaxo
     Development  Cost  obligations, the  aforesaid  10% Glaxo  Profit  and Loss
     allocation shall  be  reduced  by the  negotiated  percentage  or,  failing
     agreement,  the  result  (the  'Profit  Percentage')  of  multiplying  such
     allocation by a fraction equal to  the ratio which U.S. $6.5 million  bears
     to the total Glaxo Development Costs incurred and paid by W-L, Wellcome and
     the  JV  Entity up  to the  date of  NDA  Approval of  OTC Zantac,  if any.
     Wellcome's obligation to  fund Glaxo Development  Costs incurred after  the
     date  of  NDA Approval  of OTC  Zantac shall  also be  reduced by  the same
     proportion.
 
          (c) With respect to all products which utilize Ranitidine sold by a JV
     Entity pursuant to  the Glaxo Arrangement  in the Remainder  of the  World,
     Wellcome  shall fund  an amount equal  to 30%  of W-L's share  of all Glaxo
     Development Costs, and Glaxo Profits and Losses attributable thereto  shall
     be allocated 90% to W-L and 10% to Wellcome.
 
          (d)  With respect to all products which do not contain Ranitidine sold
     by a JV Entity  pursuant to the Glaxo  Arrangement, Wellcome shall fund  an
     amount  equal  to  10%  of  W-L's  share  of  all  Glaxo  Development Costs
     attributable thereto  and shall  be  entitled to  the allocation  of  Glaxo
     Profits  and Losses set  forth in Section 5.03(c)  hereof unless the Zantac
     trademark is utilized in
 
                                       18
 

     connection with the sale of any product which does not contain  Ranitidine,
     in  which case the  Glaxo Profits and Losses  attributable thereto shall be
     allocated in accordance with  the allocation of  Base Business Profits  and
     Losses  set  forth  in  Section 4.02(c)(iv)  of  this  Agreement  and Glaxo
     Development Costs shall be shared on the same basis.
 
          (e) Except as  provided in paragraph  (f) below, in  the event of  NDA
     Disapproval  of OTC Zantac, Wellcome shall not be entitled to reimbursement
     of any  amounts  paid  to W-L  or  contributed  to a  JV  Entity  as  Glaxo
     Development  Costs and milestone  payments pursuant to  Section 5.02 hereof
     but shall  retain its  interest  in the  Glaxo Arrangement,  including  its
     interest  in Glaxo  Profits and  Losses attributable  to OTC  Zantac in the
     United States which shall be allocated in the manner set forth in paragraph
     (b) above.
 
          (f) With respect to  OTC Zantac and any  other product resulting  from
     the Glaxo Arrangement in the United States, in the event of NDA Disapproval
     of OTC Zovirax, Wellcome shall relinquish any further interest in the Glaxo
     Arrangement,  and, except as hereafter provided, Wellcome shall be entitled
     to reimbursement by W-L of all amounts paid by it pursuant to Section  5.02
     hereof,  such amounts to be increased to reflect the financing costs of any
     such payments from the date of  original payment by Wellcome at an  assumed
     annual  interest rate on such payments equal to the prime rate charged from
     time to time by Citibank, N.A., provided, however, that if NDA  Disapproval
     of  OTC Zovirax shall  occur after NDA Disapproval  of OTC Zantac, Wellcome
     shall not be entitled  to reimbursement by  W-L of any  amounts paid by  it
     pursuant to Section 5.02 hereof.
 
          (g)  For purposes of this Section  5.03, NDA Disapproval of either OTC
     Zovirax or OTC Zantac  shall mean the absence  of any reasonable  prospects
     for  the issuance of NDA  Approval prior to January  1, 1999, or such other
     date as  may be  mutually agreed  upon by  the Parties.  In the  event  W-L
     commences termination proceedings pursuant to Section 14.02, Wellcome shall
     have no further right to participate in OTC Zantac in the United States.
 
     SECTION  5.04. Control  of Glaxo Arrangement  Products. Notwithstanding any
provision in this Agreement to the contrary, it is expressly understood that all
decisions or  determinations  by any  JV  Entity relating  to  the  development,
marketing  and  sale  by a  JV  Entity of  a  product resulting  from  the Glaxo
Arrangement including,  without limitation,  OTC Zantac,  shall be  made by  the
Governing  Board of  the JV  Entity with the  representatives of  W-L having the
determinative vote.
 
                                   ARTICLE VI
 
                                  NEW PRODUCTS
 
     SECTION 6.01. Products Developed by the  Parties. Within six months of  the
Closing  Date for each  JV Entity, the  General Manager of  such JV Entity shall
present, for the review and approval of the relevant Governing Board the  budget
for  development and the  key development projects  to be undertaken  by such JV
Entity. The  expenses for  such development  shall be  borne by  each JV  Entity
unless  discontinued by  decision of its  Governing Board and  the Base Business
Profits and  Losses of  such  products shall  be  allocated in  accordance  with
Section 4.02(c)(iv).
 
     SECTION 6.02. OTC Switch Candidates. (a) The Parties may each develop other
prescription  drug  products  as  OTC Switch  Candidates  at  each  Party's sole
discretion and cost. Prior  to the date,  or not later than  ten days after  the
date  that the Originating Party files for Regulatory Approval for an OTC Switch
Candidate or  within ten  days following  notification after  the date  of  this
Agreement  that a prescription drug product may be offered without the necessity
of a  prescription, the  Originating Party  shall offer  to the  appropriate  JV
Entity,  by written notice,  such OTC Switch  Candidate for inclusion  in the JV
Business of such JV Entity. The  Non-Originating Party shall, within six  months
after  receipt of such  notice or promptly  following notice given  to it by the
Originating Party of Regulatory Approval,  whichever is earlier, decide  whether
or  not to  accept such  OTC Switch Candidate  as JV  Business on  behalf of the
appropriate JV Entity. If  the Non-Originating Party accepts  the product as  JV
Business  on behalf of  the JV Entity,  the Originating Party  shall supply such
product at its Fully Allocated Cost plus a reasonable mark-up agreed upon by the
Parties and such product shall be added to the relevant Manufacturing and Supply
Agreement and Intellectual  Property Agreement (subject  to pre-existing  rights
of, and contractual arrangements with third parties), as the case may be, and to
such other
 
                                       19
 

Operative Documents as may be required and the Originating Party shall deliver a
certificate  to  the  Non-Originating  Party  confirming  such  matters  as  the
Non-Originating Party  may reasonably  request with  respect to  the OTC  Switch
Candidate. The Special Profit and Loss with respect to such OTC Switch Candidate
shall  be  allocated between  the Parties  in  the manner  set forth  in Section
4.02(c)(iii) and as provided for in the relevant JV Implementation Agreement. If
the Non-Originating Party does not accept  such product or does not give  notice
within  the applicable time period  referred to above and  such product does not
become part of  JV Business,  the Originating Party  may, for  its own  account,
license  such product to  a third party  for distribution or  sell its rights to
such product  to a  third  party. If  the  Originating Party,  after  reasonable
efforts  to  license or  sell such  product on  reasonable commercial  terms, is
unable to do so, such Party may  market such product pursuant to the  procedures
set  forth  in Section  6.03(b)(i). W-L  and Wellcome  shall discuss  OTC Switch
Candidates with each other  on a periodic  basis throughout the  term of the  JV
Entities,  such discussions to  be limited solely  to the potential  of such OTC
Switch Candidates to become OTC Switch Products.
 
     (b) Notwithstanding the foregoing  paragraph 6.02(a), an Originating  Party
may  propose to a Governing Board that an OTC Switch Candidate be developed by a
JV Entity. In the event the representatives of the Non-Originating Party on  the
relevant  Governing  Board shall  approve such  development, the  appropriate JV
Entity shall thereafter be  responsible for funding the  development of the  OTC
Switch  Candidate  upon  such terms  (including  funding) as  shall  be mutually
agreeable to the Parties.
 
     (c) Except  as provided  in Sections  6.03 and  6.04, neither  Party  shall
license  or  dispose of  the rights  to  market over-the-counter  a prescription
product except in connection with the bona fide disposition or licensing of  all
rights  to the  prescription product  without the  prior written  consent, which
consent shall not be unreasonably withheld or delayed, of the other Party.
 
     (d) In the event any prescription product  which is owned by a Party or  as
to  which it holds the  distribution rights is the  subject of regulatory action
which permits the product to be sold without the necessity of a prescription, or
if sold without the necessity of a prescription but enjoying cost  reimbursement
advantages  loses such reimbursement advantages,  the Parties shall negotiate in
good faith  the treatment  of such  product as  an OTC  Switch Candidate  to  be
subject to the provisions of Section 6.02(a).
 
     SECTION  6.03. Acquisition by a Party. (a) After either Party acquires, or,
at the discretion of the Originating Party, before such Party acquires, directly
or indirectly,  any  business which  includes  non-prescription drugs  or  other
consumer  health care products, such Party  shall as promptly as possible inform
the other  Party and  the relevant  Governing Board  by written  notice of  such
acquisition  or proposed acquisition,  and the appropriate  JV Entity shall have
the exclusive right  to acquire  such non-prescription drugs  or other  consumer
health  care  products included  in such  business by  indicating its  desire to
acquire such products within 30 days after receipt of such notice. In the  event
that  the JV Entity delivers written notice to the Originating Party that the JV
Entity wishes to acquire any such  products, the JV Entity shall negotiate  with
the  Originating Party to acquire such products  on an arm's-length basis but in
any event on terms no less favorable than the terms on which they were  acquired
(to the extent determinable).
 
     (b)  If the  JV Entity declines  to acquire  such products or  is unable to
reach agreement within 30 days  after the date on  which such notice was  given,
the  Originating Party may acquire (if it has not already acquired) the products
and shall  (i)  offer to  supply  the JV  Entity  with such  products  at  Fully
Allocated  Cost  plus an  appropriate  mark-up agreed  upon  by the  Parties and
request that the JV Entity market such products on a basis which assures the  JV
Entity  receipt of its Fully Allocated Cost  in connection with the marketing of
such products, plus an  appropriate mark-up determined  by reference to  similar
products sold or supplied in the same market or markets, or (ii) sell or license
such products to a third party; provided, however, that if the Originating Party
offers to sell or license such products as set forth in clause (ii) to any third
party,  the Originating Party shall offer such terms to the JV Entity in writing
prior to  entering  into any  agreement  with such  third  party on  terms  more
favorable  than last offered to the JV Entity.  The JV Entity shall then have 30
days to accept or reject such offer.  If accepted, the Parties shall proceed  to
execute  a  marketing agreement,  a  purchase and  sale  agreement or  a license
agreement, as the case may be, and if rejected or if no response is given within
the 30-day
 
                                       20
 

period, the Originating Party may enter  into an agreement with the third  party
on such terms. If the Originating Party is unable to agree with the JV Entity on
marketing  terms pursuant to clause (i) above or  to agree with a third party on
sales or license terms pursuant to clause (ii) above, the Originating Party  may
market such products itself.
 
     For  the purposes of this  Section 6.03, any actions to  be taken by the JV
Entity shall be taken by the Non-Originating Party on behalf of such JV Entity.
 
     SECTION 6.04. Acquisition by a JV Entity. If a JV Entity is considering the
acquisition  of,   directly  or   indirectly,   any  business   which   includes
non-prescription  drugs  or  other consumer  health  care products,  and  if the
relevant Governing  Board approves  such acquisition  for such  JV Entity,  such
business  and products shall  become part of  the JV Business.  If the Governing
Board determines that the JV Entity will not purchase such products and a  Party
thereafter  acquires  such products,  the  provisions of  Section  6.03(b) shall
apply.
 
     SECTION 6.05. Continuing Development. If a  product becomes part of the  JV
Business  pursuant to Section 6.02, 6.03 or 6.04, (i) any continuing development
of such product including, without limitation, any post-marketing  surveillance,
shall  be  funded by  the JV  Entity and  (ii)  each of  the Parties  shall make
available to  the  JV Entity  such  licenses related  to  and required  for  the
marketing  and sale of such product in  the relevant Territory as such Party may
hold.
 
     SECTION 6.06. Use of Information. For purposes of evaluating an OTC  Switch
Candidate  or developing and marketing an OTC  Switch Product, OTC Zovirax or JV
Prescription Zovirax, the  Originating Party  (or Wellcome  in the  case of  OTC
Zovirax  and  JV  Prescription Zovirax)  shall  (as required  elsewhere  in this
Agreement or as reasonably required to  make an informed decision in respect  of
an  OTC  Switch  Candidate)  provide information  relating  to  the formulation,
manufacture, use, safety, marketing or otherwise concerning such product to a JV
Entity or to the Non-Originating Party (or W-L in the case of OTC Zovirax and JV
Prescription Zovirax).  Such information  shall be  so provided  solely for  the
purposes  and business of the JV Entities as contemplated hereby (i.e., the non-
prescription consumer health care business and,  in the case of JV  Prescription
Zovirax,  prescription pharmaceutical business outside  the United States to the
extent specifically contemplated hereby) and for no other use and shall be  held
confidential  in accordance  with Section 15.11  of this  Agreement (but without
regard to the term of such Section 15.11).
 
                                  ARTICLE VII
 
                        MANUFACTURING; SUPPLY; SERVICES
 
     SECTION 7.01. Manufacturing and Supply. (a) The Parties agree that (i)  all
products will be manufactured by the Originating Party or its designee (each the
'Manufacturer'),  and (ii) upon shipment, the  Manufacturer shall invoice the JV
Entity for its Fully Allocated Cost of the products sold plus a mark-up, all  as
more  specifically set forth  in the relevant  Wellcome Manufacturing and Supply
Agreement or the W-L Manufacturing and Supply Agreement, as the case may be. The
Fully Allocated Cost of  any product manufactured by  any Person unrelated to  a
Party shall be the invoiced cost of such product.
 
     (b)  Any other materials required for  the wholesale or retail distribution
of products included  in JV Business  shall, subject to  any provisions of  this
Agreement  or the other Operative Documents to the contrary, be purchased by the
appropriate JV Entity from such sources and upon such terms as the JV Management
shall determine.
 
     (c) To the  extent there is  a material adverse  impact on a  JV Entity  or
either  Party due to a material change  in manufacturing production volumes as a
result of a marketing  decision, regulatory action or  other event, the  Parties
agree  to negotiate in good faith whether and to the extent an adjustment to the
Fully Allocated Cost of products sold  to mitigate such material adverse  impact
is appropriate.
 
     (d)  The Parties agree to negotiate in  good faith a method for reimbursing
the Parties for an  amount in excess of  normal depreciation charges on  capital
expenditures  related to  JV Business incurred  on projects  initiated after the
date of this Agreement.
 
                                       21
 

     SECTION 7.02. Services. The  Parties agree that (i)  all services shall  be
provided  by W-L, Wellcome or a third party as designated by the Governing Board
of the JV  Entity (each  the 'Provider'), and  (ii) monthly  the Provider  shall
invoice  the JV Entity  for the Fully  Allocated Cost of  such services provided
pursuant to the relevant  Marketing, Services and  Development Agreement plus  a
mark-up  based on such costs, all as more specifically set forth in the relevant
Wellcome Marketing, Services  and Development  Agreement or  the W-L  Marketing,
Services and Development Agreement, as the case may be. The Fully Allocated Cost
of  any  services provided  by  any Person  unrelated to  a  Party shall  be the
invoiced cost of such service.
 
     SECTION 7.03.  Operating  Issues.  Each  Manufacturer  will  enter  into  a
Manufacturing  and  Supply Agreement  substantially  in the  form  identified as
Exhibit D in the Supplemental  Document Package, completed, among other  things,
by  the addition of schedules specifying  certain terms including the following:
(i) credit terms, (ii) currency, (iii) forecasting, (iv) carriage insurance, (v)
mode of transport,  (vi) place and  time of deemed  delivery and (vii)  interest
payable  on  overdue invoices,  such terms  to  be based,  to the  extent deemed
appropriate by the Parties, on existing operating practices of the  Manufacturer
or  its Affiliate subject to subsequent  agreement of the Parties and reflecting
the requirements of  applicable local law.  It is the  intention of the  Parties
that a Manufacturer or its Affiliate supplying Existing Products to a particular
Territory  prior  to the  Closing  shall continue  to  do so  subsequent  to the
Closing, it being understood that  such products may be sold  to a JV Entity  in
the  Territory  of  manufacture for  resale  by  another JV  Entity  outside the
Territory of  manufacture.  A Manufacturer  may  solicit and  receive  technical
support and assistance from W-L or Wellcome or an Affiliate or its own personnel
pursuant  to  and as  contemplated  by the  relevant  W-L or  Wellcome Marketing
Services and Development Agreement.
 
     SECTION 7.04.  Alternate  Manufacturing  Sites.  Subject  to  the  relevant
Manufacturing  and Supply Agreement, any decision to specify an alternative site
for the manufacturing by Manufacturer or an Affiliate of Manufacturer of one  or
more  Products  shall  be made  by  the Party  to  this Agreement  which  is the
Manufacturer or an Affiliate of the Manufacturer in question.
 
     SECTION 7.05. Audits and Inspections. In accordance with the provisions set
forth in  the relevant  Manufacturing  and Supply  Agreement or  the  Marketing,
Services  and  Development Agreement,  as the  case  may be,  the Party  to this
Agreement that is  neither Manufacturer  nor Provider nor  an Affiliate  thereof
shall  be entitled  to conduct all  audits and inspections  contemplated by such
agreement on behalf of the Purchaser.
 
                                  ARTICLE VIII
 
                               CHANGE OF CONTROL
 
     SECTION 8.01. Definition of Change  of Control; Response to Third  Parties.
(a)  In the event that  a third party acquires  after the date hereof beneficial
ownership (as defined below) of 30% or more of the voting capital of Wellcome or
W-L or,  after acquiring  30%  or more,  thereafter acquires  additional  voting
capital  resulting in beneficial ownership of 50%  or more of the voting capital
of Wellcome or  W-L, as  the case  may be (the  'Affected Party'),  a Change  of
Control  will  be deemed  to have  occurred.  For the  purposes of  this Section
8.01(a) with respect to a Change of Control of W-L, a Person shall be deemed  to
have  'beneficial ownership' of, and shall  be deemed to 'beneficially own', any
securities which such Person or any of its Affiliates is deemed to 'beneficially
own' within the meaning of Rule 13d-3 under the Securities Exchange Act of  1934
and  the  rules and  regulations thereunder.  For the  purposes of  this Section
8.01(a), a Change of Control of Wellcome will be deemed to have occurred in  the
event  that any  Person acquires,  whether by a  series of  transactions or not,
shares in the  capital of  Wellcome which (taken  together with  shares held  or
acquired by persons acting in concert with such Person) carry 30% or more or 50%
or  more, as the case may  be, of the voting rights  of Wellcome, all within the
meaning of Rule 9 of the City Code on Takeovers and Mergers issued by the  Panel
on  Takeovers and Mergers in London. It is expressly understood that the present
share ownership of The  Wellcome Trust does not  constitute a Change of  Control
for  purposes of this  Section 8.01, provided, however,  that any acquisition of
beneficial ownership by  a third  party of  shares hereafter  acquired from  The
Wellcome  Trust  shall be  subject  in all  respects  to the  Change  of Control
provisions of this Agreement.
 
                                       22
 

     (b) Under no circumstances shall the Non-Affected Party inform, directly or
indirectly, any third party of what action the Non-Affected Party would or would
not take in the event of a Change  of Control until such time as such Change  of
Control  has occurred. The Non-Affected Party shall promptly notify the Affected
Party of any inquiries made by a third party (other than a regulatory authority)
relating to the subject of the preceding sentence.
 
     SECTION 8.02. Effect of Change of Control. In the event a Change of Control
of either Wellcome or  W-L shall occur, and  the Non-Affected Party believes  in
good  faith that such Change of Control is prejudicial to its interest in the JV
Entities, such  Party  shall have  the  option,  within 30  days  following  the
occurrence  of the event listed in Section  8.01(a), to exercise the rights with
respect to all JV Entities set  forth under Section 14.03(a)(i), (ii) and  (iii)
as if the cure periods of such Sections had expired in the case in which W-L was
the  Affected Party and to  exercise the rights with  respect to all JV Entities
set forth  in Section  14.04(a)(i)  and (ii)  as if  the  cure periods  of  such
Sections had expired in the case in which Wellcome was the Affected Party.
 
                                   ARTICLE IX
 
                         COVENANTS OF WELLCOME AND W-L
 
     From  and after the date of the  execution of a JV Implementation Agreement
through the Closing Date with respect to thereto, Wellcome and W-L shall  comply
with the following covenants for the Territory covered by such JV Implementation
Agreement;  provided, however,  that with respect  to the United  States, the EC
Territory, the Other European Territory, Australia and Canada, W-L and  Wellcome
shall  comply with the following covenants (other than Sections 9.04 and 9.07 in
the case of the EC  Territory and the Other  European Territory) from and  after
the   execution  of  this   Agreement  through  the  Closing   Date  of  the  JV
Implementation Agreements relating thereto.
 
     SECTION 9.01. Access.  Each Party  shall give to  the other  Party and  its
representatives   reasonable  access   during  normal  business   hours  to  the
properties, books and records of the other to the extent relating to the conduct
of the Wellcome  Contributed Business or  the W-L Contributed  Business, as  the
case  may be, and  furnish each other  with all such  information concerning the
Wellcome Contributed Business and the W-L Contributed Business, as the case  may
be, as such Party may reasonably request.
 
     SECTION  9.02. Financial  Information. Each Party  shall give  to the other
Party and its representatives the balance sheets, profit and loss statements and
other financial statements as are prepared in the normal course of such  Party's
business to the extent relating to the Wellcome Contributed Business and the W-L
Contributed  Business, as the case may be, and such other information concerning
the financial  condition  of  the  Wellcome Contributed  Business  and  the  W-L
Contributed  Business, as the case may be, as W-L or Wellcome, respectively, may
reasonably request. In  addition, each  Party shall  allow the  other Party,  at
reasonable  times  and  with  reasonable  notice,  to  have  a  Certified Public
Accountant audit such other Party's books  and accounts, at the sole expense  of
the  Party  requesting  such  audit,  to the  extent  relating  to  the Wellcome
Contributed Business or the W-L Contributed Business, as the case may be.
 
     SECTION 9.03.  Books  and  Records.  Wellcome and  W-L  shall  continue  to
maintain  the books, accounts  and records of  the Wellcome Contributed Business
and the W-L Contributed Business, as the case may be, in the usual, regular  and
ordinary  manner on a basis  consistent with prior years  and periods, except as
required by law or U.S. GAAP or U.K. GAAP, as the case may be.
 
     SECTION 9.04. Conduct of Business. (a)  Each Party shall (i) except in  the
ordinary  course of  its business  or pursuant  to this  Agreement or  any other
Operative Documents or with  the prior written consent  of the other Party,  not
sell or transfer or create a Lien on any of the Wellcome Contributed Business or
the W-L Contributed Business, as the case may be, or enter into any agreement or
arrangement  to do  the foregoing,  (ii) except  in the  ordinary course  of its
business or pursuant to the prior written consent of the other Party, not  enter
into  or renew any  material contract or  commitment, or engage  in any material
transaction,  relating  to  the  Wellcome   Contributed  Business  or  the   W-L
Contributed Business, as the case may be, (iii) except in the ordinary course of
its  business or pursuant to  the prior written consent  of the other Party, not
consent to  the  material amendment  or  termination of  any  material  contract
relating  to the Wellcome Contributed Business  or the W-L Contributed Business,
 
                                       23
 

as the  case may  be, (iv)  except in  the ordinary  course of  its business  or
pursuant to the prior written consent of the other Party, not grant any material
new licenses under any of the products to be transferred to a JV Entity, (v) use
its  reasonable  best  efforts to  preserve  for  the JV  Business  the business
relations of the Wellcome Contributed Business or the W-L Contributed  Business,
as  the case  may be,  with suppliers, customers  and others,  and (vi) promptly
notify the other Party of any event which may have a material adverse effect  on
the  Wellcome Contributed Business or the  W-L Contributed Business, as the case
may be,  including, without  limitation,  any material  governmental  complaint,
investigation or hearing of which Wellcome or W-L has been advised.
 
     (b)  Any reference in this  Section 9.04 to the  written consent of a Party
shall be deemed to require that such consent not be unreasonably withheld.
 
     SECTION 9.05. Approvals  and Consents. Each  of the Parties  shall use  its
reasonable  best efforts to (i) obtain  all governmental approvals and consents,
if any,  necessary  or  desirable  for  the  consummation  of  the  transactions
contemplated  by this Agreement  and (ii) make or  cause to be  made any and all
declarations, filings  and registrations  with governmental  authorities,  which
approvals,  consents, declarations, filings and  registrations are agreed by the
Parties to be  reasonably necessary  or desirable  for the  consummation of  the
transactions contemplated hereby.
 
     SECTION  9.06.  Regulatory.  (a)  Wellcome shall  use  its  reasonable best
efforts to obtain all Regulatory Approvals required to market and sell all  oral
solid forms of Zovirax without a prescription in the United States indicated for
the  management of recurrent  genital herpes and  in the other  countries of the
Core Territory for the cream form of OTC Zovirax in three gram or less packaging
for the treatment of cold sores and shall bear all development expenses  related
thereto.  Wellcome shall promptly notify W-L each time it submits an application
for government registration or marketing approval for any Zovirax formulation to
be sold without  a prescription, shall  promptly notify W-L  of any  significant
action  taken  on  any such  application,  shall  promptly advise  W-L  when any
Regulatory Approval has been obtained and  shall keep W-L generally informed  of
such regulatory efforts by Wellcome.
 
     (b)  Each of the Parties shall, to  the extent necessary or appropriate, in
its reasonable  opinion, give  the other  Party and  any appropriate  JV  Entity
access  to all of  the Wellcome Regulatory Documentation  and the W-L Regulatory
Documentation, as the case may be.
 
     SECTION 9.07. Further Assurances. Each of  Wellcome and W-L shall take  all
reasonable  steps to  do or cause  to be done  such further acts  and things and
deliver or cause to  be delivered to  each JV Entity  and/or its designees  such
additional  assignments,  agreements, powers  and instruments  as the  JV Entity
and/or its designees  may reasonably  require or  deem advisable  to carry  into
effect  the purpose of this  Agreement and the Operative  Documents or to better
assure and confirm unto each JV  Entity and/or its designees its rights,  powers
and remedies hereunder and thereunder.
 
     SECTION  9.08.  Tax Matters.  Each Party  and  its Affiliates  shall render
reasonable cooperation to and assist the other Party and its Affiliates and each
JV Entity in  obtaining all desirable  rulings or consents  of the relevant  and
appropriate  tax authorities agreed by the Parties to be reasonably necessary in
order to  obtain  all  appropriate  tax  benefits  for  the  Parties  and  their
Affiliates,  and the  respective JV Entities  as contemplated herein  and in the
other Operative Documents.
 
     SECTION 9.09. Employees; Sharing of Certain Costs. (a) The identity of  the
employees  working for or  to be charged  to each JV  Entity shall be determined
mutually  by  the  Parties;  provided,  however,  that  in  the  event  of   any
disagreement between the Parties, the decision of W-L shall control.
 
     (b) If, solely as a result of the formation of a JV Entity in the Remainder
of  the World, the employment of an employee  of either Party or an Affiliate is
terminated (whether by the Party or the  Affiliate or a JV Entity) or  otherwise
ceases  by operation of law on or  immediately after such formation, the Parties
shall share equally all severance and  termination costs or compensation of  the
employer  in  respect of  such termination  or cessation.  For the  avoidance of
doubt, the employment of any employee who is transferred to an employer which is
an Affiliate of either  Party (including for this  purpose any JV Entity)  shall
not  be deemed to have been terminated.  All other costs or expenses relating to
the formation and operation  of JV Entities which  are incurred by either  Party
shall be borne by such Party.

                   POST CLOSING COVENANTS OF WELLCOME AND W-L
 
     From  and after the Closing  Date with respect to  each JV Entity, Wellcome
and W-L shall  comply with the  following covenants for  the Territory in  which
such JV Entity operates.
 
     SECTION 10.01. Treatment of OTC Zovirax; Regulatory. (a) Wellcome shall use
its  reasonable  best efforts  to obtain  all  Regulatory Approvals  required to
market and sell all oral  solid forms of Zovirax  without a prescription in  the
United  States indicated for  the management of recurrent  genital herpes and in
each country in the Core Territory in  the Remainder of the World for the  cream
form  of OTC Zovirax in  three gram or less packaging  for the treatment of cold
sores and shall bear all development  expenses related thereto. The relevant  JV
Entity  shall be responsible for all pre-launch marketing and selling costs. For
the avoidance of doubt, expenses incurred  during periods when there are no  Net
Sales shall be treated as Losses. Following NDA Approval or Regulatory Approval,
as  the case  may be, of  OTC Zovirax,  any further development  of such product
shall be funded by the relevant JV Entity.
 
     (b) The Parties shall use their  reasonable best efforts to achieve  launch
for  OTC  Zovirax  in  the  United States  subsequent  to  NDA  Approval.  It is
understood that Wellcome shall be responsible for obtaining Regulatory  Approval
for  OTC Zovirax and shall have final approval of any decisions relating thereto
(including the Launch  Date thereof).  Wellcome shall promptly  notify W-L  each
time it submits an application for government registration or marketing approval
for  any  OTC  Zovirax formulation  to  be  sold without  a  prescription, shall
promptly notify W-L of any significant action taken on any such application, and
shall promptly advise  W-L when any  Regulatory Approval has  been obtained  and
shall keep W-L generally informed of such regulatory efforts by Wellcome.
 
     (c)  Subject to  Section 10.12,  the rights  disclosed pursuant  to Section
10.01(e), and  the  rights  of  third parties  in  Non-Core  Territories  to  be
disclosed prior to the Closing Date of the relevant JV Implementation Agreement,
Wellcome  shall  cause to  be granted  to  the relevant  JV Entity  an exclusive
license to use the Zovirax trademark (or,  if the Zovirax trademark is not  used
in  the relevant  country, the prescription  trademark used in  that country) in
connection with the marketing, selling or distribution of OTC Zovirax; provided,
however, that Wellcome shall not be bound to grant a license to use the  Zovirax
trademark  in respect of any Territory if  it can demonstrate, to the reasonable
satisfaction of W-L's representatives on the Governing Board of the relevant  JV
Entity,  a regulatory or compelling commercial  reason why such trademark should
not be used  in such Territory  and Wellcome  shall not itself  use the  Zovirax
trademark  or  such alternative  prescription trademark  in connection  with OTC
Zovirax, and shall not grant  to any other Person a  license to use the  Zovirax
trademark  in either case for the  non-prescription sale of consumer health care
products. In the event the Zovirax trademark is not used in a Territory pursuant
to the proviso of the preceding sentence, the Parties shall consult with respect
to the selection, development  and use of a  suitable alternative trademark  the
form and use of which shall be subject to Wellcome's approval.
 
     (d)  Wellcome will  not, and  will assure  that its  Affiliates do  not, do
anything which is likely to derogate from  the rights to be granted pursuant  to
the  Zovirax License  Agreements to  enjoy the  benefits of  OTC Zovirax thereby
conveyed or to impede the JV Entity's ability to realize such rights.
 
     (e) Subject to the rights of third parties in Core Territories existing  at
the  date of this Agreement  which have been disclosed to  W-L prior to the date
hereof, it is expressly understood by  the Parties that any Zovirax  formulation
or  indication to be  marketed and sold  without a prescription  in a country in
which a JV Entity has been established  shall be marketed and sold only  through
such JV Entity; provided, however, that Wellcome shall not be required to switch
any  products from the prescription to the non-prescription market except to the
extent set forth in Section 9.06(a) of this Agreement.
 
     SECTION 10.02. Further Assurances. (a) Each of Wellcome and W-L shall  take
all  reasonable steps to do or cause to be done such further acts and things and
deliver or cause to  be delivered to  each JV Entity  and/or its designees  such
additional  assignments,  agreements, powers  and instruments  as the  JV Entity
and/or its designees  may reasonably  require or  deem advisable  to carry  into
effect  the purpose of this  Agreement and the Operative  Documents or to better
assure and confirm unto each JV  Entity and/or its designees its rights,  powers
and remedies hereunder and thereunder.
 
                                       25
 

     (b) Each of Wellcome and W-L shall continue to comply with the covenant set
forth in Section 9.06(b) of this Agreement.
 
     SECTION  10.03. Tax Matters. Each Party  and its Affiliates shall cooperate
fully with and assist the other Party  and its Affiliates and each JV Entity  in
obtaining  all desirable rulings or consents of the relevant and appropriate tax
authorities agreed by the Parties to be reasonably necessary in order to  obtain
all  appropriate  tax  benefits  for  the  Parties,  their  Affiliates  and  the
respective JV  Entities  as  contemplated  herein and  in  the  other  Operative
Documents.  Neither Party shall cause any tax election to be made by a JV Entity
which would have the effect of imposing a disproportionate liability for any tax
on the other Party or any of its Affiliates.
 
     SECTION 10.04. U.S. Export Controls Compliance; Restrictive Trade Practices
Act 1976. (a)  The Parties  acknowledge that  the products to  be sold  by a  JV
Entity  may be subject to  export controls on resales  and/or transfers to other
countries and  parties including  authorizations required  from the  appropriate
U.S.  government agency under the  laws and regulations of  the United States of
America. No  JV Entity  shall be  authorized to  act in  violation of  any  law,
including, without limitation, Part 769 of the Export Administration Regulations
of  the U.S. Department of Commerce and/or  agree to participate in a boycott as
defined in Section 999 of  the U.S. Internal Revenue  Code of 1986, as  amended.
Each of the Parties and their appropriate Affiliates shall assist the JV Entity,
as  requested and where  practicable, in seeking  U.S. government authorizations
for transactions subject to U.S. export control regulations.
 
     (b)  If  there  is  any  provision   of  this  Agreement,  or  of  any   JV
Implementation Agreement or other Operative Document which causes or would cause
this  Agreement or that Agreement  or other Operative Document  to be subject to
registration under the Restrictive Trade Practices Act 1976 ('RTPA'), then  that
provision  shall  not  take  effect  until the  day  after  particulars  of such
Agreement or Operative Document (as the case may be) have been furnished to  the
Director General of Fair Trading pursuant to Section 24 RTPA.
 
     SECTION  10.05. JV  Entity Books  and Records; Audits.  (a) Each  of the JV
Entities shall maintain its books and  records in accordance with U.S. GAAP  and
in  sufficient detail to permit their conversion to U.K. GAAP by Wellcome and in
accordance with such other accounting principles  as may be required by the  law
of the jurisdiction in which such JV Entity is organized.
 
     (b)  Each of W-L and  Wellcome, on such occasions  as it may request, shall
have the right to have its Certified Public Accountants or its internal auditors
audit, examine or review the books, records and operations of each other to  the
extent relevant to the JV Business and of each JV Entity, but at the cost of the
Party requesting such audit, examination or review.
 
     (c)  Policies with  respect to internal  audit functions of  each JV Entity
shall be as determined by the General Manager of such JV Entity.
 
     (d) Each Party and its Affiliates shall provide, on a timely basis, each JV
Entity with information necessary to meet the requirements of Section 3.10(b).
 
     SECTION  10.06.  Intellectual   Property  Rights.  With   respect  to   the
intellectual  property  rights  included  in the  Wellcome  and  W-L Contributed
Business, Wellcome, W-L and each JV  Entity (i) shall, promptly following  their
becoming  aware thereof, notify the relevant  Governing Board of (A) any adverse
determination in any proceeding in the United States Patent and Trademark Office
or United  States Copyright  Office  or comparable  foreign  bodies or  (B)  the
institution  of  any proceeding  or any  adverse  determination in  any Federal,
state, local or  foreign court  or administrative body  regarding Wellcome's  or
W-L's  claim  of  ownership in  or  right to  use  any  of the  Wellcome  or W-L
trademarks, patents, know-how or other intellectual property rights, their right
to register the  same, or  to keep and  maintain such  registration, (ii)  shall
properly  maintain  and  care  for the  Wellcome  and  W-L  trademarks, patents,
know-how or  other intellectual  property  rights owned  by  such Party  or  its
Affiliates  to  the  extent  necessary  for the  conduct  of  the  JV Businesses
(including, without limitation, by taking all reasonable legal action  necessary
to  protect  the  Wellcome  and  W-L  trademarks,  patents,  know-how  or  other
intellectual property  rights owned  by  such Party  or its  Affiliates  against
infringement  by third parties)  and (iii) shall  not permit to  lapse or become
abandoned, settle or  compromise any  pending or future  material litigation  or
material  administrative  proceeding  without first  having  consulted  with W-L
 
                                       26
 

or Wellcome, as the case may be, as to the impact of the same on the relevant JV
Business, all  as  more  fully  set  forth  in  the  relevant  W-L  or  Wellcome
Intellectual Property Agreement.
 
     SECTION  10.07. Access. Each  Party shall give  to the other  Party and its
representatives  reasonable  access   during  normal  business   hours  to   the
properties, books and records of the other to the extent relating to the conduct
of  the Wellcome  Contributed Business or  the W-L Contributed  Business, as the
case may be,  and furnish each  other with  all such information  to the  extent
concerning  the Wellcome Contributed Business  and the W-L Contributed Business,
as the case  may be, as  such Party may  reasonably request and  which shall  be
necessary  for the conduct of the JV Business of any JV Entity after the Closing
Date.
 
     SECTION 10.08. Benefit of Contracts.  Wellcome and W-L recognize and  agree
that,  notwithstanding other provisions  of this Agreement  to the contrary, the
Parties may  identify contracts  the assignment  of which  are not  commercially
practicable  and third party consents  to the transfer, in  whole or in part, of
licenses, intellectual property rights and contracts which are necessary to  the
conduct  of the Wellcome  Contributed Business or  the W-L Contributed Business,
which consents may not  be obtainable or may  not be obtainable on  commercially
reasonable  terms  by the  Party responsible  therefor.  Such contracts  will be
identified to each of the Parties and in such circumstances, Wellcome or W-L, as
the case  may be,  or their  appropriate Affiliate,  shall for  the benefit  and
account  of  the appropriate  JV  Entity, act  under  such licenses,  rights and
contracts in the manner most effective under the circumstances so as to  provide
their  value and benefit to such JV Entity, in each case to the extent permitted
by law, and will evidence or confirm such arrangement to the extent requested by
the other Party or the JV Entity.  Nothing in this Agreement shall be  construed
as  an attempt to assign any such license,  right or contract to the extent such
assignment is not  permitted by law  or by the  terms of the  license, right  or
contract in question.
 
     SECTION  10.09. Use of Parent Names. (a) Except as otherwise agreed by each
of the Parties, the  name of each  JV Entity shall  be Warner Wellcome  Consumer
Health  Products, together with such identifier as  may be required by law. Each
of the  Parties acknowledges  that a  JV Entity  may in  its conduct  of the  JV
Business be required or may desire to use the corporate names of such Party, its
subsidiaries  and its divisions and the corporate logos of each and correlatives
of the same in labelling products included in the JV Business, and on stationery
and promotional materials of the JV Entity. Upon agreement as to such use,  such
Party  shall extend to each JV Entity a royalty free license for these purposes;
provided, however, that (i) the manner of  use made of such name or logos  shall
have  been approved in writing  in advance of its use  by the relevant Party and
(ii) in the event a Party and its  Affiliate cease to be participants in the  JV
Entity,  whether pursuant  to Article XIV  hereof or otherwise,  (x) the license
contemplated by this Section 10.09 shall immediately terminate, subject only  to
a  right of the  JV Entity to use  existing stocks of  labelling materials for a
period of  not more  than one  year from  the date  of such  termination  unless
otherwise  required by either Party which will  undertake to bear the expense of
any more restrictive  limitation and  (y) the  name of  the JV  Entity shall  be
changed  as promptly  as commercially practicable  to eliminate the  name of the
Party which has ceased to be a participant.
 
     (b) Subject  to  Section 10.09(a),  to  the  extent the  Parties  agree  to
register  the name  'Warner Wellcome'  in any  jurisdiction, such  name shall be
registered jointly  in  the  names  of  W-L  and  Wellcome  (or  any  respective
Affiliates designated by each) if authorized by applicable law or regulation. In
any jurisdiction where joint registration is not authorized by applicable law or
regulation,  registration  of  the name  'Warner  Wellcome' shall  be  made only
pursuant to such agreements  relating to joint  ownership, registration and  the
use thereof as are mutually agreed to by the Parties.
 
     SECTION 10.10. Competition. (a) Subject to the provisions of any agreements
which  exist on the date hereof and  local law in a particular country, Wellcome
and W-L each covenant  and agree that  for the term of  this Agreement and  each
Operative  Document, neither  it nor  any of  its Affiliates  shall, directly or
indirectly, compete with  the JV Business  of a  JV Entity in  the Territory  in
which  it  operates by  engaging in  the  non-prescription consumer  health care
business  by  manufacturing,   marketing,  selling   or  distributing   products
competitive  with those  of the  relevant JV  Business, in  each case  except as
otherwise provided  or contemplated  by this  Agreement or  any other  Operative
Agreement;  provided,  however,  that  this provision  shall  not  apply  to (i)
non-prescription consumer health care products
 
                                       27
 

manufactured by either Party on the date hereof which have not been included  in
Schedules  1.01(b)  and  (c)  to  the  Supplemental  Document  Package  and line
extensions thereof (so long as such line extensions are not competitive with any
JV Business then conducted by a JV Entity; (ii) any products developed  pursuant
to  the Glaxo Arrangement; (iii)  manufacturing products for a  third party by a
Party to  the extent  no information  which is  proprietary to,  or  exclusively
licensed under an Intellectual Property Agreement, to a JV Entity is used in the
manufacturing   of  such  products;  or  (iv)  the  development,  manufacturing,
marketing, selling or distribution of  any non-prescription generic health  care
product  that is principally marketed,  sold or distributed through non-consumer
marketing channels. Except as  specifically provided herein  with respect to  JV
Prescription  Zovirax in the  Remainder of the World,  nothing in this Agreement
shall be deemed to hinder, restrain or limit the ability of either Party or  any
of  its  Affiliates  to engage  in  the business  of  developing, manufacturing,
marketing, selling and distributing prescription pharmaceutical products in  any
Territory, as such business is now carried on or may hereafter develop.
 
     (b)  Assets have been or will be conveyed and licenses have been or will be
granted by W-L, Wellcome  and/or their respective Affiliates  to each of the  JV
Entities  for the  purpose of permitting  sales of the  products representing JV
Business in certain  Territories. Accordingly,  each of W-L  and Wellcome  shall
take  such actions as are necessary to prevent the JV Entities from selling such
products outside of the relevant Territories.
 
     SECTION 10.11.  Insurance.  (a)  Each Party  shall  maintain  insurance  in
respect of its equity interest in the U.S. Partnership that is both adequate and
appropriate  for  the  conduct  of  the  JV  Business  with  reputable  insurers
(including, where  the Party  believes  it appropriate,  through  self-insurance
programs) against loss or damage, including fire, loss, theft, casualty, recall,
product  liability and general insurance and no costs of such insurance shall be
charged to any JV Entity. W-L shall provide directors and officers insurance and
any other forms  of insurance  required to  be obtained  by a  JV Entity  (e.g.,
automobile  insurance)  and shall  charge the  cost thereof  to the  relevant JV
Entity.
 
     (b) Without prejudice to  Section 2.02(d), the  provisions of this  Section
10.11  as applicable to the U.S. Partnership and  as it may be extended to other
Territories, shall be subject to such  amendment as may be desirable,  including
in relation to the EC Territory and Other European Territory, to take account of
all relevant factors, including, without limitation, taxation.
 
     (c)  Each Party shall  maintain insurance in relation  to any real property
owned by it,  whether freehold or  leasehold, occupied  by a JV  Entity and  the
costs thereof shall be charged to the relevant JV Entity.
 
     SECTION  10.12. JV Prescription Zovirax. To the extent Wellcome markets and
sells JV Prescription Zovirax in a specific Territory, such marketing and  sales
will  be undertaken by Wellcome on behalf  of the relevant JV Entity pursuant to
marketing arrangements to  be agreed upon  by the Parties  and reflected in  the
appropriate Marketing, Services and Development Agreement. Wellcome shall market
such  products with at least the same  degree of effort as is currently utilized
(subject to any change in circumstances) and use its reasonable best efforts  to
maximize  the profits  of the  JV Entity attributable  to any  such marketing by
Wellcome of JV Prescription Zovirax in the Territory. In the event that Wellcome
introduces another  form  of Zovirax  or  combination product  thereof  for  the
treatment  of cold sores to be sold  by prescription which results in a material
diversion of profits from JV Prescription Zovirax, the Parties agree to  discuss
in  good faith whether any adjustment to the allocation of Base Business Profits
and Losses or other action is appropriate.
 
     SECTION 10.13. Scope of JV Business; Non-Violation of Existing Obligations.
The Parties shall not, and shall not  permit any JV Entity to, knowingly  expand
the  intended scope of  the JV Businesses  and shall not  knowingly, through the
activities of  a  JV  Entity,  violate any  valid  provision  of  a  non-compete
obligation  of either Party which exists on  the date of this Agreement or which
is hereafter agreed to by the Governing Board of the relevant JV Entity.
 
     SECTION 10.14. Conduct of Business. (a) With respect to each JV Entity,  to
the extent Net Sales made by the Parties in the two calendar months prior to the
Closing  Date (or  its effective date  in the  case of the  U.S. Partnership) in
respect of  the JV  Entity (i)  are  deemed to  be Excess  Sales, and  (ii)  the
Variable  Profit Contribution of  such Excess Sales results  in an allocation of
profits other than that which
 
                                       28
 

would have resulted if  such profits had  been earned by the  JV Entity and  the
Variable  Profit Contribution had  been Base Business  Profit, the Parties shall
negotiate to determine the extent to which the advantaged Party shall compensate
the disadvantaged party for such differential profit allocation. In the case  of
the  U.S. Partnership,  any determination under  this Section  10.14(a) shall be
based on the use of sales as normally reported by the Parties in accordance with
U.S. GAAP rather than Net Sales in all calculations.
 
     (b) To the extent sales orders for Existing Products of the Parties  remain
unfilled  as of  the Closing Date,  such orders  shall be transferred  to the JV
Entity.
 
                                   ARTICLE XI
 
                 CONDITIONS TO WELLCOME'S AND W-L'S OBLIGATIONS
 
     The Closing  of the  transactions contemplated  by each  JV  Implementation
Agreement  shall be subject  to the satisfaction  at or prior  to the Closing of
such transactions of  the following  conditions; provided,  however, that  after
December 31, 1995, either Party may terminate this Agreement if these conditions
have  not been met or waived with respect to the countries in the Core Territory
in which a JV  Entity has not  been established (it  being understood that  such
period may be extended by mutual written consent of the Parties).
 
     SECTION   11.01.  Certain  Action.   At  the  Closing   Date  for  each  JV
Implementation Agreement,  no suit,  action, investigation  or other  proceeding
will  have been  instituted and  be pending  by any  governmental agency  of the
relevant Territory  or any  other Person  in  which it  is sought  to  restrain,
prohibit, invalidate or set aside generally the transactions contemplated by the
relevant  JV Implementation Agreement and the other Operative Documents referred
to therein.
 
     SECTION 11.02. Government Approvals and  Consents. At the Closing Date  for
each  JV Implementation Agreement, all necessary filings (other than in relation
to marketing approvals) required, if any, in or for the relevant Territory  with
the  appropriate governmental or other authorities in or for such Territory will
have been made and all necessary governmental approvals (other than in  relation
to  marketing approvals),  if any,  will have  been received  and any prescribed
waiting periods will have expired or been terminated. No government entity shall
have indicated its objection to, or its intent to challenge as violative of  any
federal,  state or  foreign laws, any  of the transactions  contemplated by this
Agreement  or  the  relevant  JV  Implementation  Agreements.  In  the  event  a
government  entity places  a condition  on its  approval of  the transactions as
contemplated by  the Operative  Documents which  has a  material effect  on  the
Wellcome Contributed Business or the W-L Contributed Business, the Parties shall
attempt  to  negotiate  a mutually  agreeable  modification to  the  relevant JV
Implementation Agreement and the other appropriate Operative Documents.
 
     SECTION 11.03. Tax Rulings. The Parties shall have applied for and received
all rulings or consents  of the appropriate tax  authorities which either  Party
reasonably  believes to be necessary  or desirable in order  to implement the JV
Implementation Agreement in the relevant Territory as contemplated herein and in
the other Operative Documents.
 
     SECTION 11.04.  Representations  and  Warranties.  The  representations  of
Wellcome  and W-L contained  in the Representations  and Warranties Agreement in
respect of certain countries in the Core Territory shall continue to be true and
correct in  all  material respects  as  of  the date  the  representations  were
originally  given. In addition, there shall have been no material adverse change
in the condition of the Wellcome or W-L Contributed Business since the  original
date  of  such  representations.  In  connection  with  the  execution  of  a JV
Implementation Agreement for a  country in the  Non-Core Territory, the  Parties
shall agree upon such representations and warranties as shall be appropriate.
 
     SECTION  11.05. Performance of  Covenants. Each Party  shall have performed
and complied in all  material respects with each  and every covenant,  agreement
and  condition contemplated by this Agreement and the relevant JV Implementation
Agreement to be performed or complied with by it prior to or on the Closing Date
for the relevant JV Implementation Agreement.
 
     SECTION 11.06. Authorization of Agreements. All action on the part of  each
Party  necessary to  authorize the execution,  delivery and  performance of this
Agreement, the relevant JV Implementation
 
                                       29
 

Agreements and the Operative Documents, and the consummation of the transactions
contemplated herein and therein, shall have been duly and validly taken by  each
Party,  and each Party shall have furnished  to the other Party a certificate of
the Secretary or an Assistant Secretary of W-L or Wellcome, as the case may  be,
setting  forth copies of  the resolutions or  other instruments authorizing this
Agreement, the relevant JV Implementation Agreements and the Operative Documents
and the transactions contemplated herein and therein.
 
     SECTION 11.07. Execution  of Operative Documents.  All Operative  Documents
required  by the  relevant JV  Implementation Agreement  in order  to permit the
appropriate JV Entity to  conduct JV Business in  the appropriate country  shall
have been executed and delivered and shall be fully effective in all respects.
 
     SECTION  11.08. Certificate of Compliance. Each  Party shall deliver to the
other Party a  certificate of an  authorized officer of  such Party,  certifying
compliance with the conditions set forth in this Article XI.
 
     SECTION  11.09. Assignment  of Certain  Contracts and  Licenses. Each Party
shall  have  obtained  the  consent,  as  appropriate,  in  form  and  substance
satisfactory  to the  other Party,  to the  assignment to  the JV  Entity in the
relevant Territory  of  all  material  contracts,  product  licenses  and  other
instruments  which  are part  of the  Wellcome Contributed  Business or  the W-L
Contributed Business, as the case may be, for the relevant Territory, or  either
alternative  arrangements shall have been made  in accordance with Section 10.08
or undertakings reasonably  acceptable to  the Parties shall  have been  entered
into.  Notwithstanding the provisions of Section  4.07(d), a JV Entity shall not
become responsible  for any  contract  which is  a part  of  or related  to  the
Wellcome  or  W-L Contributed  Business except  to the  extent such  contract is
specifically identified in an Operative Document  as being assigned in whole  or
in part or made available in accordance with Section 10.08.
 
                                  ARTICLE XII
                       TRANSFER OF JOINT VENTURE INTEREST
 
     SECTION  12.01. Limitation  on Right  to Transfer.  A Party  or any  of its
Affiliates may  not sell,  assign, pledge,  hypothecate or  otherwise  delegate,
subcontract or transfer in any manner, all or any part of its interest in the JV
Business,  any JV Entity, this Agreement  or the Operative Documents unless such
transfer (i)  is  permitted under  Section  12.02  of this  Agreement,  (ii)  is
consented to in writing by the other Party in its sole discretion, with specific
reference  to this Section 12.01, (iii)  is permitted in accordance with Article
XIV or (iv) is permitted  by an Operative Document.  In addition, to the  extent
necessary to be classified as a partnership for United States Federal income tax
purposes, the interest in a JV Entity held principally by a JV Entity which is a
holding   company  shall  be  non-transferable  except  between  Persons  owning
interests in such JV Entity.
 
     SECTION 12.02.  Permitted  Transfers. Nothing  in  this Article  XII  shall
prevent  the transfer  by any Party  of all  or part of  its interest  in any JV
Business, any  JV Entity,  this Agreement  or the  Operative Documents  if  such
interest   is  transferred  to  an  organization   which  is  an  Affiliate  and
wholly-owned (subject to directors' qualifying shares), directly or  indirectly,
by  Wellcome or W-L, as the case may be, but only for so long as it shall remain
an Affiliate of, and wholly-owned, directly  or indirectly by, Wellcome or  W-L;
provided, however, that (i) the JV Implementation Agreement for a JV Entity that
is capable of being classified as a partnership for United States Federal income
tax  purposes shall not permit a transfer of an interest in such JV Entity if it
would prejudice such classification of such  entity; (ii) that no such  transfer
shall  be effective unless  the transferee of any  interest so transferred under
this Section 12.02  shall have  assumed by  express agreement  with the  Parties
hereto  (in form and substance satisfactory to the relevant Governing Board) all
of the  obligations of  the transferor  under this  Agreement and  that no  such
transfer shall relieve the transferor of its obligations under this Agreement in
the  event the transferee fails to perform its obligations hereunder and (iii) a
Party (or any of its Affiliates) shall not transfer its interest in a JV  Entity
which  is  classified as  a  partnership for  United  States Federal  income tax
purposes in a manner  which would constitute a  termination of such  partnership
under Section 708(b)(1)(B) of the Internal Revenue Code of 1986, as amended from
time  to time,  and any  successor statute.  Upon such  transfer such transferee
shall be admitted as a Party, in
 
                                       30
 

addition to the Party which was the transferor. In the event that any  Affiliate
shall  cease to be an Affiliate within  the meaning of this Section, Wellcome or
W-L, as  the case  may be,  shall  assure that  immediately prior  thereto  such
interest  is transferred  back to  Wellcome or  W-L or  one of  their respective
Affiliates as appropriate.
 
                                  ARTICLE XIII
                                INDEMNIFICATION
 
     SECTION 13.01. Responsibility for Liabilities and Expenses. (a) Each of W-L
and Wellcome shall  be separately  responsible for, and  hereby indemnifies  the
other  Party and  each JV  Entity (on  an after-tax  basis) against  all claims,
liabilities,  damages,  losses,  expenses  (including  reasonable  legal  fees),
obligations, liens, assessments, judgments and fines (all of the foregoing being
a  'Claim') made by or  owed to any Person to  the extent attributable to death,
bodily injuries, pain  or damages  suffered, or obligations  or liabilities  and
which  arose out of such  Party's ownership or operation  of the W-L Contributed
Business or the Wellcome Contributed Business, as the case may be, prior to  the
Closing  Date for the Territory in question. Such Claims shall also include, but
not be limited to, all Taxes due by such  Party and as to which a JV Entity  may
be  jointly liable for payment with such Party. If the use of the product giving
rise to the Claim occurred  prior to the Closing Date,  such Claim shall be  the
responsibility of W-L or Wellcome, as the case may be (depending on whether such
product  was part  of the W-L  Contributed Business or  the Wellcome Contributed
Business).
 
     (b) Subject to Section 13.01, each  JV Entity shall indemnify and hold  W-L
and  Wellcome and their  respective Affiliates harmless  (on an after-tax basis)
for all product  liability Claims arising  out of the  JV Business conducted  by
that  JV Entity on or after the  Closing Date of the JV Implementation Agreement
for such JV Entity; provided, however, that (i) as to any Claims arising out  of
defects  in the manufacture of any product  included in JV Business conducted by
that JV Entity, W-L or Wellcome, whichever shall have manufactured such product,
shall indemnify and hold harmless (on an after-tax basis) the JV Entity and  the
Party  which did  not manufacture such  product to  the extent agreed  to in the
relevant Manufacturing and Supply Agreement and  (ii) W-L shall not be  entitled
to  any indemnification  under this  Section 13.01(b) to  the extent  a court of
competent jurisdiction shall have finally determined that the product  liability
Claim  in question arose  from the failure  of W-L to  have used reasonable best
efforts to satisfy the  standard of conduct  set forth in  Section 4.08 of  this
Agreement.
 
     (c)  To the  extent any  Claim is based  on use  of any  product or damages
sustained over a  period of time  beginning prior  to the Closing  Date for  the
relevant JV Implementation Agreement and continuing after such Closing Date, the
liability  and costs  of a  JV Entity relating  to such  Claim shall  be for the
account of Wellcome, W-L or the JV Entity, as the case may be. Damages based  on
the  time prior to such Closing Date, if any, shall be for the account of W-L or
Wellcome, as the case may  be, and for the time  on and after such Closing  Date
for the relevant JV Entity.
 
     (d)  To the extent sales returns occurring  on or after the Closing Date in
respect of sales prior thereto are deemed  by the Parties to be in the  ordinary
course  of business, the cost of such returns  shall be borne by the relevant JV
Entities. To the extent the Parties  agree that such sales returns occurring  on
or  after the Closing Date are outside the ordinary course of business, the cost
of such returns shall be borne by the responsible Party provided, however,  that
for  purposes  of this  Section 13.01(d),  product discontinuations  and product
withdrawals shall  be deemed  to be  outside the  ordinary course  of  business.
Products  returned in a re-salable condition  shall be returned to the inventory
of the relevant JV Entities.
 
     (e) Where any claim, litigation  or arbitration is contemplated,  commenced
or  brought (a)  by any  JV Entity  against any  Party or  any Affiliate  or (b)
against any JV Entity by any Party or any Affiliate, irrespective of the  amount
involved   therein,  the  Party   shall  ensure  that   any  officer,  director,
representative or agent of  it or any  Affiliate shall not  be involved in  such
claim,  litigation or arbitration on  behalf of the JV  Entity and shall have no
vote in determining whether such  claim, litigation or arbitration is  commenced
or  is made or in any matters relating to the conduct or settlement thereof. The
provisions of this Section 13.01(e) shall apply, mutatis mutandis, to the making
of any decision by a
 
                                       31
 

JV Entity to terminate any  agreement between a Party  or any Affiliate and  the
relevant  JV  Entity  other than  one  entered  into by  the  relevant  Party or
Affiliate solely as a partner or shareholder and not in any other capacity.
 
     SECTION 13.02. Indemnification. (a) W-L  shall indemnify and hold  Wellcome
and  each JV Entity harmless (on an after-tax basis) from all Claims suffered or
paid as a result of (i) the failure of any of the representations or  warranties
made  by W-L in  this Agreement or any  other Operative Document  to be true and
correct in all material respects as of the date hereof or any applicable Closing
Date, (ii) any breach by  W-L of any covenant made  by W-L in this Agreement  or
any  of the Operative Documents and (iii) any Claim made by a third party which,
if successful, would constitute  a breach of a  warranty, covenant or  agreement
made  by W-L in this  Agreement or any other  Operative Document, subject in all
cases to any limitations set forth in this Agreement or any Operative Document.
 
     (b) Wellcome shall indemnify and hold  W-L and each JV Entity harmless  (on
an  after-tax basis)  from all Claims  suffered or paid  as a result  of (i) the
failure of any  of the representations  or warranties made  by Wellcome in  this
Agreement or any other Operative Document to be true and correct in all material
respects  as of the date hereof or  any applicable closing date, (ii) any breach
by Wellcome of any  covenant made by  Wellcome in this Agreement  or any of  the
other  Operative Documents,  (iii) any  Claims made by  a third  party which, if
successful, would constitute a breach of a warranty, covenant or agreement  made
by  Wellcome in this Agreement  or any other Operative  Document, subject in all
cases to any limitations set forth  in this Agreement or any Operative  Document
and  (iv) the termination  of any broker  previously engaged by  Wellcome in the
United States  the  services  of which  have  not  been continued  by  the  U.S.
Partnership after January 31, 1994.
 
     (c)  Subject to the requirements of  Section 13.02(a) or (b) as applicable,
in the event a judgment shall be  rendered by a court of competent  jurisdiction
against  only one of the Parties or another  liability is incurred and paid by a
Party in its capacity as  a partner of any JV  Entity conducting JV Business  in
partnership  form (except any judgment obtained by  a third party as a result of
the negligence  of that  Party or  breach by  that Party  of the  terms of  this
Agreement or any Operative Document), the other Party shall reimburse such Party
for  that percentage of  such judgment or  liability as shall  correspond to the
appropriate profit and loss  allocation to the  reimbursing Party applicable  to
the  product giving rise to the judgment, or if the judgment is not related to a
specific product, the Base Business Profit and Loss allocation for the  relevant
JV Entity.
 
     (d)  If a  JV Entity incurs  liability for  any Tax in  connection with any
actual or deemed  contribution or transfer  to a JV  Entity at the  time of  its
formation  of any tangible or intangible assets, property or business, including
the grant of  any license, lease  or similar right  (collectively, 'Assets')  or
with respect to a Party's prior ownership or operation of such Assets, the Party
transferring  or contributing (or causing such transfer or contribution of) such
Assets will indemnify and  hold harmless (on an  after-tax basis) the JV  Entity
from  any liability (net  of any refund  or similar recovery)  in respect of any
such Tax, including all costs and expenses directly or indirectly related to the
final determination of the JV Entity's liability  for such Tax. In the event  an
Affiliate  of a Party shall  be involved in the  transfer or contribution of the
Assets, the Party and  the Affiliate shall be  jointly and severally liable  for
the indemnification set forth in the preceding sentence.
 
     (e)  Any indemnification  of a JV  Entity, W-L or  Wellcome hereunder shall
include and  extend to  the  benefit of  their respective  directors,  officers,
employees  and representatives  or alternative representatives  of the Governing
Board and Affiliates (other than any  indemnification by Wellcome of an  officer
or  director which  is proscribed by  law). Any  person that may  be entitled to
indemnification under this Agreement (an 'Indemnified Party') shall give  notice
to  the  Person  obligated  to  indemnify  it  (an  'Indemnifying  Party')  with
reasonable promptness upon becoming aware of any claim or other facts upon which
a claim  for indemnification  will be  based; the  notice shall  set forth  such
information  with  respect  thereto  as  is  then  reasonably  available  to the
Indemnified Party. The Indemnifying Party shall have the right to undertake  the
defense of any such Claim asserted by a third party with counsel satisfactory to
the  Indemnified Party and the Indemnified Party shall cooperate in such defense
and make available all records, materials and witnesses reasonably requested  by
the  Indemnifying  Party in  connection  therewith at  the  Indemnifying Party's
expense. If the Indemnifying Party shall  have assumed the defense of the  claim
with  counsel reasonably satisfactory to the Indemnified Party, the Indemnifying
 
                                       32
 

Party shall  not be  liable to  the Indemnified  Party for  any legal  or  other
expenses  (other  than  for  reasonable  costs  of  investigation)  subsequently
incurred by the Indemnified  Party in connection with  the defense thereof.  The
Indemnifying  Party  shall  not be  liable  for  any claim  settled  without its
consent, which consent may not be unreasonably withheld or delayed.
 
     (f) To the  extent that either  Party is involved  in any proceeding  which
arose  prior to the  establishment of a  JV Entity and  books, records or former
employees of the Party shall be under  the dominion and control of a JV  Entity,
the  JV Entity shall  cooperate with the  Party and make  available all records,
materials and witnesses reasonably requested by the Party in connection with its
prosecution or defense of such proceeding at the Party's expense.
 
                                  ARTICLE XIV
                              TERM AND TERMINATION
 
     SECTION 14.01. Term of JV Entity. Each  JV Entity shall commence as of  the
Closing Date for the relevant JV Implementation Agreement for such JV Entity and
shall continue until it is dissolved and terminated pursuant to the terms of the
Operative  Documents or pursuant to law.  Except in those circumstances referred
to in Sections 8.02, 14.02, 14.03 and 14.04 and except for circumstances causing
dissolution or  liquidation of  a JV  Entity set  forth in  a JV  Implementation
Agreement  it  is understood  and  agreed that  each  JV Entity  is  intended to
continue without interruption until such relationship is specifically  dissolved
by  unanimous consent of the  partners or shareholders, as  the case may be, and
that upon  dissolution the  rights and  obligations of  the Parties  under  this
Agreement  shall continue to be  in effect, until the  final distribution of the
assets of each JV Entity to the Parties.
 
     SECTION 14.02.  OTC Zovirax  Not Approved.  (a) Notwithstanding  any  other
provision of this Agreement, if an event set forth in Section 4.02(c)(ii)(B) has
occurred  and the Parties have been unable  to agree upon increased or decreased
allocations pursuant to that Section within six months from the delivery of  the
written  notice referred to in that Section, W-L may, in its sole discretion (as
its exclusive remedy), commence the  termination procedures set forth in  clause
(b) of this Section by giving written notice thereof to Wellcome.
 
     (b) Notwithstanding any other provision of this Agreement, in the event W-L
delivers  a  notice  pursuant to  paragraph  (a)  of its  intention  to commence
termination, the Parties shall  have the following  rights and obligations  with
respect  to all, but not fewer than all, of the JV Entities in the United States
and Canada:
 
          (i) Wellcome may, in its sole  discretion, elect to withdraw from  the
     JV  Entities in the United  States and Canada all  products included in the
     Wellcome Contributed Business  together with OTC  Zovirax, JV  Prescription
     Zovirax and any OTC Switch Product as to which Wellcome was the Originating
     Party, that constitute JV Business in the United States and Canada;
 
          (ii)  Wellcome may,  in its sole  discretion, elect to  require W-L to
     purchase all right, title  and interest of Wellcome  in the JV Entities  in
     the  United States  and Canada,  including the  JV Entities'  rights in the
     Operative Documents, but excluding any interest of such JV Entities in  OTC
     Zovirax,  JV  Prescription  Zovirax, any  OTC  Switch Product  as  to which
     Wellcome was the Originating Party, for an amount equal to 30% of the value
     of the JV Entity in the United States and 50% of the value of the JV Entity
     in Canada as  of the end  of the most  recent Fiscal Quarter  as valued  at
     their  Going  Concern  Value;  provided,  however,  that  for  purposes  of
     determining Going  Concern  Value  for  this Section,  no  value  shall  be
     ascribed  to  OTC Zovirax,  JV Prescription  Zovirax,  any such  OTC Switch
     Product; or
 
          (iii) Wellcome may, in its sole  discretion, elect to sell any of  the
     products  included in the Wellcome  Contributed Business withdrawn from the
     JV Business pursuant to clause (i) to one or more third parties,  provided,
     however,  that if Wellcome offers or  negotiates to sell such products with
     any third party Wellcome shall offer such terms to W-L in writing prior  to
     entering  into any  agreement with such  third party.  W-L shall thereafter
     have 30 days to accept or reject such offer. If accepted, the Parties shall
     proceed to execute a purchase and sale agreement, and if rejected or if  no
     response  is  given within  the 30-day  period, Wellcome  may enter  into a
     purchase and sale agreement with the third party on such terms.
 
                                       33
 

     (c) It is expressly understood that in the event of any election of  rights
by  Wellcome pursuant to Section 14.02(b), (i) Wellcome shall receive all rights
to the marketing  of OTC  Zovirax, JV Prescription  Zovirax and  any OTC  Switch
Products  as to which  Wellcome was the Originating  Party,(ii) Wellcome will be
promptly compensated by W-L for its interest  in the Going Concern Value of  any
products  developed  by  the JV  Entity  (other  than Line  Extensions)  and any
products acquired by  the JV Entity  pursuant to Sections  6.03 and 6.04,  (iii)
Wellcome will promptly pay to W-L the Going Concern Value of its interest in OTC
Zovirax  and JV Prescription Zovirax in Canada and in all OTC Switch Products as
to which Wellcome  was the Originating  Party in the  United States and  Canada,
(iv)  Wellcome will  not retain  any interest  in the  Glaxo Arrangement  in the
United States  and Canada  and  will not  be compensated  for  the loss  of  its
interest  (other than, with respect to Canada, as included in the calculation of
the Going  Concern  Value  of  the  JV Entity  in  Canada  set  forth  above  in
subparagraph  (b)(ii)  and other  than as  provided in  Section 5.03(f)  and (v)
Wellcome shall have no further interest in the JV Entities in the United  States
and  Canada. An election permitted by Wellcome pursuant to the foregoing clauses
(i), (ii) and (iii)  shall be made  within six months  of Wellcome's receipt  of
W-L's  notice  of intention  to commence  termination and  shall be  recorded by
written notice delivered by Wellcome to  W-L. Any such notice by Wellcome  shall
be irrevocable and not subject to change except by agreement of the Parties.
 
     (d)  In the event  W-L delivers a  notice pursuant to  paragraph (a) of its
intention to commence termination, Wellcome may,  in its sole discretion and  in
addition to the rights set forth in paragraph (b), elect to withdraw from the JV
Entities  in  the Remainder  of  the World  (other  than Canada).  In  such case
Wellcome shall  have the  right to  elect either  of the  options set  forth  in
Section  14.03(a)  below. An  election permitted  by  Wellcome pursuant  to this
paragraph (d) shall  be made within  six months of  Wellcome's receipt of  W-L's
notice  of intention  to commence termination  and shall be  recorded by written
notice delivered  by Wellcome  to W-L.  Any  such notice  by Wellcome  shall  be
irrevocable  and not subject to change except by agreement of the parties. It is
expressly understood that any  election by Wellcome  pursuant to this  paragraph
(d) shall mean that Wellcome shall have commenced termination of the relevant JV
Entities  in the Remainder of the World  (other than Canada) for purposes of the
penultimate sentence of Section 14.08.
 
     SECTION 14.03. Wellcome Events of Termination; Remedies. In the event  that
(x)  there is an NDA Approval for OTC  Zovirax within the time periods set forth
in Section 4.02(c)(ii)(B), (y) there has  been a successful renegotiation of  an
increased  allocation of  Special Profits or  a decreased  allocation of Special
Losses to W-L pursuant  to Section 4.02(c)(ii)(B) or  (z) W-L has not  commenced
the  termination procedures set  forth in Section 14.02  within the time periods
set forth therein, and Wellcome is  dissatisfied with the performance of any  of
the  JV Entities in (1) the United States and Canada or (2) the Remainder of the
World (other than Canada), as the case may be, Wellcome may give written  notice
to   W-L  setting   forth  in  reasonable   detail  the   basis  for  Wellcome's
dissatisfaction with such JV Entities (all of such JV Entities in (1) the United
States and Canada or  (2) the Remainder  of the World  (other than Canada),  the
'Affected JV Entities'), it being understood that Wellcome's dissatisfaction may
not  relate to  the Plans for  OTC Zovirax,  JV Prescription Zovirax  or any OTC
Switch Product  as  to  which  Wellcome was  the  Originating  Party,  but  such
dissatisfaction  may  relate  to a  material  breach  of any  provision  of this
Agreement or any of the other  Operative Documents by W-L or the  implementation
by  the relevant JV Entity (other than through Wellcome or its employees) of any
Plan for OTC Zovirax, JV  Prescription Zovirax or any  OTC Switch Product as  to
which  Wellcome was the Originating Party. Following receipt of such notice, W-L
shall have one year to attempt to cure the cause of Wellcome's  dissatisfaction.
W-L  shall use its reasonable efforts to attempt to cure the cause of Wellcome's
dissatisfaction unless W-L does not  intend to cure such dissatisfaction  within
such  one year period. In the latter  case, W-L shall notify Wellcome in writing
and such one year  period shall be deemed  to terminate as of  the date of  such
notice.  If,  in the  reasonable opinion  of Wellcome,  the cause  of Wellcome's
dissatisfaction has not  been cured  within one year  of W-L's  receipt of  such
written  notice and such one year cure period expires or has terminated pursuant
to the previous sentence, then
 
          (a) After the second anniversary and prior to the fifth anniversary of
     the Closing Date  for the initial  JV Implementation Agreement  in (1)  the
     United  States or Canada if the Affected JV Entity is located in the United
     States or Canada or (2)  any other Territory if  the Affected JV Entity  is
     located  in the Remainder of the World (other than Canada), as the case may
     be, Wellcome shall
 
                                       34
 

     have the right to, within 30  days after expiration or termination of  such
     one  year cure period by  written notice (which shall  be irrevocable as to
     the election made) sent to W-L:
 
             (i) elect to withdraw  from the Affected  JV Entities any  products
        included in the Wellcome Contributed Business together with OTC Zovirax,
        JV  Prescription Zovirax and any OTC Switch Product as to which Wellcome
        was the Originating Party, that constitute JV Business of such  Affected
        JV Entities. In such event W-L shall compensate Wellcome for the loss of
        its interest in the Affected JV Entities' JV Business represented by the
        Going  Concern Value of any  OTC Switch Product as  to which W-L was the
        Originating Party and  any products  developed by the  JV Entity  (other
        than  Line  Extensions)  and  any products  acquired  by  the  JV Entity
        pursuant to Sections 6.03  and 6.04. Wellcome  shall compensate W-L  for
        the  loss of its interest in the affected JV Business represented by the
        Going Concern Value of (1) OTC Zovirax, if the affected JV Entity is  in
        the  United States and (2)  any OTC Switch Product  as to which Wellcome
        was the Originating Party. In the event Wellcome transfers its  interest
        in  OTC Zovirax (if the  Affected JV Entity is  in the United States) or
        any OTC Switch Product as to which Wellcome was the Originating Party to
        a third  party within  twelve months  after Wellcome  has withdrawn  its
        products  from such  JV Entities pursuant  to this  clause (i), Wellcome
        shall pay  to W-L  an amount  equal to  W-L's appropriate  share of  any
        amounts  so received  (calculated on  an after-tax  basis) in  excess of
        Going Concern Value of  OTC Zovirax or such  OTC Switch Product, as  the
        case  may be. In the event of  any election pursuant to this clause (i),
        Wellcome will retain its rights and obligations in the Glaxo Arrangement
        but shall relinquish any and all remaining interest in such Affected  JV
        Entities;
 
             (ii)  elect to withdraw from the Affected JV Entities all rights to
        JV Prescription Zovirax, OTC Zovirax and  any OTC Switch Products as  to
        which  Wellcome was the Originating Party.  W-L shall pay to Wellcome an
        amount equal to the Going Concern  Value of the remainder of  Wellcome's
        interest  in such Affected JV Entities (excluding any value attributable
        to JV Prescription Zovirax, OTC Zovirax and any such OTC Switch Products
        but including the  value of  the Glaxo  Arrangement and  all OTC  Switch
        Products  as to  which W-L  was the  Originating Party)  as of  the most
        recently completed Fiscal Quarter. Wellcome shall compensate W-L for the
        loss of its  interest in  the JV Business  of the  Affected JV  Entities
        represented  by the Going Concern Value  of JV Prescription Zovirax, OTC
        Zovirax and any such  OTC Switch Products.  In addition, Wellcome  shall
        pay  to W-L an amount  equal to the minimal  necessary costs of reducing
        the scope of such JV  Entities' activities due to Wellcome's  withdrawal
        of  JV  Prescription  Zovirax,  OTC Zovirax  and  any  other  OTC Switch
        Products as to which  Wellcome was the Originating  Party. In the  event
        Wellcome  transfers its interest in OTC Zovirax, JV Prescription Zovirax
        and any OTC  Switch Product  as to  which Wellcome  was the  Originating
        Party to a third party within twelve months after Wellcome has withdrawn
        OTC  Zovirax, JV  Prescription Zovirax and  any such  OTC Switch Product
        from any JV Entities pursuant to this clause (ii), Wellcome shall pay to
        W-L an  amount  equal to  W-L's  appropriate  share of  any  amounts  so
        received  (calculated on an after-tax basis)  in excess of Going Concern
        Value for  OTC  Zovirax, JV  Prescription  Zovirax or  such  OTC  Switch
        Product,  as the case may  be. In the event  of any election pursuant to
        this clause (ii), Wellcome  shall not retain any  interest in the  Glaxo
        Arrangement  and  shall not  be compensated  for  such loss  of interest
        (other than as included in the calculation of the Going Concern Value of
        the Affected JV Entities set forth above in the event and to the  extent
        Wellcome  participates in the Glaxo  Arrangement pursuant to Article V);
        or
 
             (iii) elect to  sell its  entire economic  interest, including  the
        Glaxo  Arrangement,  JV Prescription  Zovirax, OTC  Zovirax and  all OTC
        Switch Products as to which Wellcome  was the Originating Party, in  the
        Affected  JV Entities to W-L at a price to be negotiated by the Parties.
        If the Parties are unable to agree upon a price within a period of three
        months, Wellcome may offer to sell its entire economic interest in  such
        Affected  JV  Entities  to  a  third  party,  including  JV Prescription
        Zovirax, OTC Zovirax and  all OTC Switch Products  as to which  Wellcome
        was  the  Originating Party  but excluding  the Glaxo  Arrangement which
        shall be acquired by W-L  pursuant to Section 14.05; provided,  however,
        that  if Wellcome negotiates the sale of its entire economic interest in
        such   Affected   JV    Entities   to   a    third   party   on    price
 
                                       35
 

        and  other material commercial terms that  are more favorable than those
        last offered to W-L, Wellcome shall offer the terms of such third  party
        offer  to W-L in writing prior to  entering into any agreement with such
        third party. W-L shall then have 30 days to accept or reject such offer.
        If accepted,  the  Parties  shall  proceed to  finalize  such  sale  and
        purchase,  and if rejected or if no  response is given within the 30 day
        period, Wellcome  may sell  such interest  to the  third party  on  such
        terms;  provided, however, that  the identity of  such third party shall
        have been approved by W-L with any such approval not to be  unreasonably
        withheld  and not to be withheld based solely on the fact that the third
        party is a competitor of W-L or of a JV Entity;
 
          (b) At any time  on or after  the fifth anniversary  and prior to  the
     tenth  anniversary of  the Closing Date  for the  initial JV Implementation
     Agreement in (1) the United States or  Canada if the Affected JV Entity  is
     located  in the United States  or Canada or (2)  any other Territory if the
     Affected JV Entity  is located in  the Remainder of  the World (other  than
     Canada),  as the case may be, Wellcome shall have the right, within 30 days
     after expiration or  termination of such  one year cure  period by  written
     notice (which shall be irrevocable as to the election made) sent to W-L, to
     elect  either of  the options set  forth in Section  14.03(a)(ii) and (iii)
     above;
 
          (c) At any time on or after the tenth anniversary of the Closing  Date
     for  the initial  JV Implementation Agreement  in (1) the  United States or
     Canada if the Affected JV Entity is located in the United States or  Canada
     or  (2) any  other Territory if  the Affected  JV Entity is  located in the
     Remainder of the World  (other than Canada), as  the case may be,  Wellcome
     shall  have the  right, within 30  days after expiration  or termination of
     such one year  cure period  by written  notice sent  to W-L,  to elect  the
     option set forth in Section 14.03(a)(iii);
 
provided,  however, that in the event that Wellcome elects any of the above with
respect to a JV Entity in (1)  the United States or Canada, such election  shall
also  apply  to all  JV  Entities in  the  United States  or  Canada or  (2) the
Remainder of the World  (other than Canada), such  election shall also apply  to
all  other JV Entities in the Remainder of the World (other than Canada). In the
event of an  election by Wellcome  pursuant to Section  14.03(a)(i) or (ii)  the
affected JV Entities may cause arrangements to be effected whereby Wellcome will
acquire the relevant products.
 
     Wellcome  may,  in its  discretion, elect  the option  set forth  in clause
(a)(iii) at  any time  after the  receipt of  the NDA  Approval referred  to  in
Section  4.02(c)(ii)(A)(1) or there has been a successful renegotiation pursuant
to Section 4.02(c)(ii)(B);  provided, however,  that W-L has  not commenced  the
termination  procedures set forth in Section 14.02  or 14.04 for the Affected JV
Entities.
 
     SECTION 14.04. W-L Events of Termination;  Remedies. In the event that  (x)
there  is an NDA Approval  for OTC Zovirax within the  time periods set forth in
Section 4.02(c)(ii)(B),  (y) there  has been  a successful  renegotiation of  an
increased  allocation of  Special Profits or  a decreased  allocation of Special
Losses to W-L pursuant  to Section 4.02(c)(ii)(B) or  (z) W-L has not  commenced
the  termination procedures set  forth in Section 14.02  within the time periods
set forth therein, and W-L  is dissatisfied with the  performance of any of  the
Affected  JV Entities in (i) the United  States and Canada or (ii) the Remainder
of the World (other than Canada) as the case may be, W-L may give written notice
to  Wellcome  setting   forth  in   reasonable  detail  the   basis  for   W-L's
dissatisfaction  with the Affected  JV Entities, it  being understood that W-L's
dissatisfaction may only relate  to the Plans for  JV Prescription Zovirax,  OTC
Zovirax or any OTC Switch Product as to which Wellcome was the Originating Party
except to the extent that the aforementioned Plans were prepared by the affected
JV  Entity other  than at the  direction of Wellcome  (W-L's dissatisfaction not
being based solely on implementation of such Plan other than by Wellcome or  its
employees),  or a material breach  of any provision of  this Agreement or any of
the other Operative  Documents by  Wellcome. Following receipt  of such  notice,
Wellcome   shall  have  one  year  to  attempt   to  cure  the  cause  of  W-L's
dissatisfaction. Wellcome shall use  reasonable efforts to  attempt to cure  the
cause  of W-L's  dissatisfaction unless  Wellcome does  not intend  to cure such
dissatisfaction within such one-year period. In the latter case, Wellcome  shall
notify  W-L in writing and such one year  period shall be deemed to terminate as
of the date of such notice. If  Wellcome, in the reasonable opinion of W-L,  has
failed  to cure such dissatisfaction within one  year of receipt of such written
notice, and such one year cure period expires or has terminated pursuant to  the
previous sentence, then
 
                                       36
 

          (a) After the second and prior to the fifth anniversary of the Closing
     Date  for the initial JV Implementation  Agreement in (A) the United States
     and Canada if the  Affected JV Entity  is located in  the United States  or
     Canada,  or  (B) the  Remainder of  the  World (other  than Canada)  if the
     Affected JV Entity is in the Remainder of the World (other than Canada), as
     the case  may  be, W-L  shall  have the  right  to, within  30  days  after
     expiration  or termination of  such one year cure  period by written notice
     (which shall be irrevocable as to the election made) sent to Wellcome:
 
             (i) return to Wellcome all of the products included in the Wellcome
        Contributed Business together with OTC Zovirax, JV Prescription  Zovirax
        and  any OTC  Switch Product  as to  which Wellcome  was the Originating
        Party, that  constitute JV  Business of  the Affected  JV Entities,  and
        Wellcome  shall pay to W-L  an amount equal to  50% of the Going Concern
        Value of W-L's interest in OTC Zovirax in the United States and any  OTC
        Switch Products as to which Wellcome was the Originating Party as of the
        most  recently  completed Fiscal  Quarter  preceding the  date  of W-L's
        election. W-L shall compensate Wellcome for the loss of its interest  in
        the  JV Business  of the Affected  JV Entities represented  by the Going
        Concern Value  of  any  OTC Switch  Product  as  to which  W-L  was  the
        Originating  Party and  any products developed  by the  JV Entity (other
        than the Line  Extensions) and any  products acquired by  the JV  Entity
        pursuant  to  Sections  6.03 and  6.04.  In  the event  of  any election
        pursuant to  this  clause (i),  Wellcome  shall retain  its  rights  and
        obligations in the Glaxo Arrangement; or
 
             (ii)  return to Wellcome  JV Prescription Zovirax,  OTC Zovirax and
        any OTC Switch Products as to  which Wellcome was the Originating  Party
        and,  in such event, W-L shall  compensate Wellcome for the remainder of
        its  interest  in  the  Affected   JV  Entities  (excluding  any   value
        attributable  to  JV Prescription  Zovirax,  OTC Zovirax,  any  such OTC
        Switch Products  or  the  Glaxo  Arrangement  but  including  any  value
        attributable  to  any  OTC  Switch  Product  as  to  which  W-L  was the
        Originating Party)  on a  basis  to be  negotiated  by the  Parties.  In
        addition,  Wellcome shall pay  W-L an amount  equal to 50%  of the Going
        Concern Value of its  interest in JV  Prescription Zovirax, OTC  Zovirax
        and  any  such OTC  Switch Products  as of  the most  recently completed
        Fiscal Quarter. In  the event of  any election pursuant  to this  clause
        (b),  Wellcome  shall retain  its rights  and  obligations in  the Glaxo
        Arrangement;
 
          (b) At any time on or after the fifth anniversary of the Closing  Date
     for  the initial JV  Implementation Agreement in (A)  the United States and
     Canada, if the Affected JV Entity is in the United States or Canada or  (B)
     the Remainder of the World (other than Canada) if the Affected JV Entity is
     in  the Remainder of the World (other than Canada), as the case may be, W-L
     shall have the right to, within 30 days after expiration or termination  of
     such  one year cure period by written notice (which shall be irrevocable as
     to the election made)  sent to Wellcome  to elect the  option set forth  in
     Section 14.04(a)(ii);
 
provided,  however, that  in the  event that  W-L elects  any of  the above with
respect to a JV Entity  in (i) the United States  or Canada such election  shall
also  apply to all other JV Entities in  the United States or Canada or (ii) the
Remainder of the World  (other than Canada), such  election shall also apply  to
all other JV Entities in the Remainder of the World (other than Canada).
 
     In  the event W-L exercises the option set forth in clause (a)(i), Wellcome
may elect to  sell its  interest in  the Affected JV  Entities to  W-L at  Going
Concern  Value (excluding any value attributable to JV Prescription Zovirax, OTC
Zovirax, any OTC Switch Products as to which Wellcome was the Originating  Party
and  the Glaxo Arrangement) and retain JV Prescription Zovirax, OTC Zovirax, any
OTC Switch  Products as  to which  Wellcome was  the Originating  Party and  its
interest  in the Glaxo Arrangement and compensate W-L as set forth in and to the
extent required by clause (a)(ii) above. If the Parties are unable to agree upon
a price within a period of three  months, Wellcome may offer to sell its  entire
economic  interest in the Affected JV  Entities excluding any value attributable
to OTC Zovirax, JV Prescription Zovirax and any OTC Switch Products as to  which
Wellcome  was the Originating Party to a third party; provided, however, that if
Wellcome offers such interest to a third party on price and other material terms
that are more favorable than those last offered to W-L, Wellcome shall offer the
terms of such third  party offer to  W-L in writing prior  to entering into  any
agreement with such third party. W-L shall then have 30 days to accept or reject
such  offer. If accepted,  the Parties shall  proceed to finalize  such sale and
purchase, and if rejected or if no response is given
 
                                       37
 

within the 30-day  period, Wellcome may  sell such interest  to the third  party
only on such terms. In the event of any election pursuant to Section 14.04(a)(i)
as  a result of which Wellcome has  retained rights and obligations in the Glaxo
Arrangement, that retained interest shall be limited to the extent of any  prior
affirmative  elections made by Wellcome pursuant to Section 5.01(b) and Wellcome
shall have no continuing  right to make any  further elections pursuant to  that
Section.
 
     SECTION  14.05. W-L's Option  to Purchase Wellcome's  Interest in the Glaxo
Arrangement; Wellcome Tag-Along  Right. (a) Notwithstanding  the provisions  set
forth in Sections 14.03 and 14.04, and in the event that Wellcome or W-L, as the
case  may be, has elected to exercise  any of the provisions for termination set
forth in Sections 14.03 or 14.04, W-L, at its sole option, after giving Wellcome
written notice of its  intention to purchase Wellcome's  entire interest in  the
Glaxo Arrangement, shall negotiate in good faith to purchase such interest for a
price to reflect the value thereof but without ascribing any value to Wellcome's
interest  in the Glaxo Arrangement except  for products currently being marketed
or under development.  If, after 60  days, the  Parties cannot agree  on such  a
price,  W-L shall  send written  notice to  Wellcome that  W-L still  intends to
purchase Wellcome's  interest  in  the  Glaxo Arrangement,  and  W-L  shall  pay
Wellcome  the Going Concern Value of  Wellcome's interest as determined pursuant
to Section 15.03  within 30 days  following receipt of  the calculation of  such
amount.
 
     (b)  In the event W-L  shall assign, sell or  otherwise transfer its entire
interest in  the  Glaxo Arrangement  to  a third  party,  W-L will  assure  that
Wellcome's  interest in  the Glaxo  Arrangement is  assigned, sold  or otherwise
transferred on equivalent terms, and, in  such event, Wellcome hereby agrees  to
any such sale, assignment or transfer.
 
     SECTION 14.06. Waiver of Right to Terminate. Notwithstanding the foregoing,
in  the event that a Party fails to give a notice of termination within the time
periods set forth  in Section 14.03  or 14.04, as  the case may  be, such  Party
shall  be deemed to have waived its right to terminate with respect to the event
or events which gave rise to such right to terminate.
 
     SECTION 14.07. Winding  Up and  Transfer of Assets;  Liquidation. Upon  the
occurrence  of an event of termination set  forth in Section 8.02, 14.01, 14.02,
14.03 or 14.04, the relevant  JV Entity shall continue  to exist solely for  the
purposes  of winding up its affairs in an orderly manner, liquidating its assets
and satisfying the claims of its creditors and its shareholders. No Party  shall
take  any action that is  inconsistent with, or not  necessary to or appropriate
for, winding up the business and affairs of any JV Entity. During the period  of
winding  up, the rights and obligations set forth in this Agreement with respect
to the management of any JV Entity  shall continue and, subject to Section  5.04
hereof,  the  relevant  Governing Board  shall  continue to  make  all decisions
relating to the conduct of any  remaining business or operations, including  any
decisions  relating to  the sale or  other disposition  of any assets  of any JV
Entity; provided, however, that if dissolution occurs as a result of an election
of a Party pursuant to Section 8.02, 14.01, 14.02, 14.03 or 14.04, then W-L  and
its  representatives on the relevant  Governing Board, unless other arrangements
are agreed to  by the Parties,  shall have the  exclusive right to  wind up  the
business  of the Affected JV Entities and to liquidate their assets and may also
elect to exercise the right to continue the business of the Affected JV Entities
in accordance with relevant law.
 
     SECTION 14.08. Rationalization  of Interests; Tax  Indemnification. In  the
event  of any restructuring event which occurs  pursuant to Section 8.02 or this
Article XIV, the capital  accounts or capital stock  accounts of the Parties  in
the  JV Entities affected by the restructuring  event shall be dealt with in the
manner provided by  the relevant  JV Implementation  Agreement. In  the event  a
Party  shall commence  termination of  a JV Entity  pursuant to  14.02, 14.03 or
14.04 or shall have undergone a Change of Control pursuant to Section 8.02, that
Party shall indemnify the  JV Entity on  an after-tax basis  for any income  tax
liability  of the JV Entity attributable  to such termination. The Parties shall
cooperate  to  minimize  any  adverse   tax  consequences  resulting  from   the
application of the provisions of this Article XIV.
 
     SECTION  14.09.  Termination  of  Related  Agreements.  In  the  event that
Wellcome withdraws  any products  or W-L  returns any  products to  Wellcome  in
accordance  with this Article XIV, the Wellcome Operative Documents with respect
to such products  shall terminate  with respect  to such  products following  an
orderly  transition period, except to the  extent such termination is agreed not
to be  necessary based  on  the commercial  requirements  of the  Parties.  With
respect  to  any  products not  withdrawn  or returned,  the  Wellcome Operative
Documents shall survive in accordance with their
 
                                       38
 

respective terms upon any termination of this Agreement; provided, however, that
in the event W-L  purchases Wellcome's interest in  any JV Entities pursuant  to
Article XIV, such Operative Documents shall terminate unless otherwise agreed by
the  Parties, and Wellcome  shall assign, without  additional consideration, its
entire right, title and  interest in and to  the affected products or  otherwise
make  such products available to W-L  on an irrevocable, exclusive, royalty-free
(subject to any applicable third party royalties) and perpetual basis, it  being
understood that the valuation of Wellcome's interest shall reflect the transfers
contemplated  by this proviso. Any payment  by W-L for Wellcome's interest shall
be made to  Wellcome or its  Affiliates as  their interests may  appear. In  the
event  products  are  returned to  Wellcome,  the Parties  shall  use reasonable
efforts to accommodate each other's needs in respect of transition arrangements,
including, without  limitation,  the transfer  of  any regulatory  approvals  or
licenses with respect to such products.
 
     SECTION  14.10. Failure to  Satisfy Required Conditions.  In the event that
any transaction contemplated  by the provisions  of this Article  XIV cannot  be
consummated by reason of the inability to satisfy any governmental, statutory or
regulatory  approval or  consent which  may be  required as  a condition  to the
consummation thereof, including,  without limitation, any  required approval  of
Wellcome  shareholders having  been sought and  not given, the  Parties agree to
negotiate in good faith, subject to  their respective fiduciary duties (and  any
required  approvals or consents), an alternative to the transaction which cannot
be so consummated  with a  view to  obtaining for each  of the  Parties (in  the
manner  most effective  under the  circumstances) the  economic benefits desired
under the application provisions of this Article XIV.
 
     SECTION 14.11. Definitional Clarification. For purposes of Sections  14.02,
14.03  and 14.04  of this  Article XIV,  the term  Wellcome Contributed Business
shall be deemed to exclude OTC Zovirax and JV Prescription Zovirax.
 
                                   ARTICLE XV
                                    GENERAL
 
     SECTION 15.01. Expenses.  Wellcome and  W-L shall bear  their own  expenses
incurred  in connection with this Agreement  and the Operative Documents and the
consummation of the transactions contemplated hereby and thereby and preparation
therefor, including,  without  limitation,  all  expenses  of  their  respective
representatives  on each  Governing Board and  all Taxes  incurred in connection
with the  assignment  and transfer  of  any assets  to  a JV  Entity;  provided,
however,  that each Party shall,  and shall cause such  JV Entity, to the extent
legally able to do so, to deliver to any other Party that is required by law  to
collect any such transfer or similar taxes an exemption certificate, in form and
substance  satisfactory to such Party, with respect to such Taxes. In connection
with the application of this Section  15.01, the Parties shall cooperate  within
reason to minimize any tax consequences to both Parties.
 
     SECTION  15.02. Assignment and Binding Effect. Subject to the provisions of
Article XII, this Agreement and any of the rights or obligations hereunder shall
not be assignable by any  Party without the prior  written consent of the  other
Party  hereto. This Agreement shall be binding  upon and inure to the benefit of
the Parties hereto and their respective permitted successors and assigns.
 
     SECTION 15.03. Inability  to Agree  Upon Value.  In the  event the  Parties
cannot  agree on any determination of Going Concern Value, the fair market value
of a product or the fair market value of a contribution to a JV Entity within  a
period of 90 days following the event requiring the determination of such value,
each  Party shall  choose an investment  banker to determine  such Going Concern
Value or other  value, which Going  Concern Value  or other value  shall be  the
average  of the  two values  determined by  such investment  bankers, unless the
higher value exceeds the lower value by more than ten percent, in which case the
Going Concern Value or other value shall be  one or the other of such values  as
decided by an investment banker selected by the first two investment bankers.
 
     SECTION  15.04. Financial Consolidation. To  the extent presently permitted
by U.S. GAAP, the Parties intend that W-L shall consolidate the sales of each JV
Entity for U.S. GAAP financial reporting purposes.
 
                                       39

     (b) If and to the extent that any court of competent jurisdiction holds any

unenforceable, such holding shall in no way affect the validity of the remainder

     SECTION 15.11. Confidentiality. (a) No Party shall, during the period while

after  all other  provisions of  this Agreement  have ended  or been terminated,

     SECTION  15.12. Governing Law; Jurisdiction; Consent to Service of Process;
Agent for Service. (a) This Agreement shall be governed, construed and  enforced
in  accordance with  the laws  of the State  of New  York without  regard to the
applicable principles of conflicts of laws that might otherwise govern.
 
     (b) Each of the Parties hereby irrevocably and unconditionally submits, for
itself and its property, to the jurisdiction of any New York State court sitting
in New York or any Federal court of the United States sitting in the Borough  of
Manhattan  in the City of New York, and any appellate court from any such court,
in any suit, action or proceeding arising  out of or relating to this  Agreement
or  any of  the Operative  Documents, or for  recognition or  enforcement of any
judgment, and each of the Parties hereto hereby irrevocably and  unconditionally
agrees  that all claims in respect of any such suit, action or proceeding may be
heard and determined in such New York State court or, to the extent permitted by
law, by removal or  otherwise, in such  Federal court. It  shall be a  condition
precedent  to each Party's  right to bring  any such suit,  action or proceeding
that such suit, action or proceeding, in the first instance, be brought in  such
New  York  State  court  or, to  the  extent  permitted by  law,  by  removal or
otherwise, in such  Federal court  (unless such  suit, action  or proceeding  is
brought  solely to obtain  discovery or to  enforce a judgment),  and if each of
such New York state court and such Federal court refuses to accept  jurisdiction
with  respect thereto,  such suit,  action or proceeding  may be  brought in any
other court with jurisdiction. Neither Party may move to (i) transfer any  suit,
action  or proceeding from such New York State court or Federal court to another
jurisdiction, (ii) consolidate any  such suit, action  or proceeding brought  in
such  New York State court or Federal court with a suit, action or proceeding in
another jurisdiction  or  (iii) dismiss  any  such suit,  action  or  proceeding
brought in such New York

State  court or Federal court  for the purposes of  bringing the same in another
jurisdiction. Each Party agrees that a  final judgment in any such suit,  action
or  proceeding shall be conclusive and may be enforced in any other jurisdiction
by suit on the judgment or in any other manner provided by law.
 
     (c) Each of the Parties  hereby irrevocably and unconditionally waives,  to
the  fullest extent it may legally and effectively do so, any objection which it
may now  or hereafter  have  to the  laying  of venue  of  any suit,  action  or
proceeding  arising out of or relating to this Agreement or any of the Operative
Documents in any New York State court  sitting in New York or any Federal  court
