     GLOBAL   PRINCIPLES  AGREEMENT   dated  as   of  December   10,  1993  (the
'Agreement'), by  and between  WARNER-LAMBERT  COMPANY, a  Delaware  corporation
('W-L')  and GLAXO HOLDINGS p.l.c., a  company incorporated in England and Wales
('Glaxo').
 
                             PRELIMINARY STATEMENT
 
     W-L is  engaged  in  the non-prescription  consumer  health  care  products
business.  Glaxo  or  its  Affiliates  own  certain  rights  in  respect  of the
pharmaceutical compound Ranitidine, which is currently marketed in  prescription
form  under the trademark Zantac'r'. W-L and  Glaxo desire to agree upon certain
principles for  the development  and marketing  of Ranitidine  Products and  the
development  and  marketing  of  certain other  consumer  health  care products,
initially in the United States and at future dates in other countries throughout
the world. While the specific form of  the joint ventures to be implemented  may
vary  in  different  countries, it  is  the  intention of  the  Parties  by this
Agreement to  agree upon  certain principles  which will  govern  the  worldwide
strategic development and marketing of all such products.
 
     NOW,  THEREFORE, in consideration of the premises and the mutual covenants,
agreements, representations and warranties herein contained, and for other  good
and  valuable  consideration the  receipt and  sufficiency  of which  are hereby
acknowledged, the  Parties,  intending to  be  legally bound,  hereby  agree  as
follows:

following definitions:
 
     'Affiliate' with  respect  to  any  Person, shall  mean  any  other  Person
controlling,  controlled by or under direct or indirect common control with such
Person. A Person shall be deemed, for the purposes of this Agreement, to control
a  corporation  (or  other  entity)  if  such  Person  possesses,  directly   or
indirectly,  the power to  direct or cause  the direction of  the management and
policies of such corporation (or other entity), whether through the ownership of
voting securities, by contract or otherwise. For the purposes of this Agreement,
a JV Entity shall not be deemed to be an Affiliate of W-L or Glaxo.
 
     'Business Day' shall mean a day of the year in which banks are not required
or authorized to close in New York City or in the City of London.
 
     'Closing Documents' shall mean  this Agreement, the Development  Agreement,

Rights Agreement, the Standstill Agreement and the W-L Services Agreement.
 
     'Development Agreement' shall mean the Development Agreement to be executed
at the Closing of this Agreement among Glaxo Inc., W-L and the U.S.  Partnership

approved on June 25, 1938, as amended and supplemented.
 
     'Fully  Allocated Cost' shall  mean all costs,  including materials, direct
and indirect labor, services and an appropriate allocation of fixed and variable
overhead expenses, but excluding any intercompany profits relating thereto,  the
determination of which shall, in respect of manufacturing, be in accordance with
Schedule  1.01(a), and shall otherwise be as agreed between the Parties or their
Affiliates in the relevant Operative Document or otherwise.
 
     'Glaxo Inc.' shall mean Glaxo Inc., a North Carolina corporation, which  is
an indirect wholly owned Affiliate of Glaxo.
 
     'Glaxo  OTC' shall mean Glaxo OTC Inc., a Delaware corporation, which is an
indirect wholly owned Affiliate of Glaxo.
 

     'Glaxo Participant' shall mean, in respect of each JV Entity, Glaxo or such
direct or indirect wholly owned Affiliate of  Glaxo as may from time to time  be
the  partner or other  equity participant in  such JV Entity  in accordance with
this Agreement.
 
     'Glaxo Products' shall mean, as at the Closing of this Agreement, Zantac in

such  business were freely tradeable in the  open market (and, for the avoidance
of doubt,  taking into  consideration any  continuing arrangements  pursuant  to
Section  14.04 hereof).  Such valuation  will  not reflect either  a premium for
control or a discount for lack of marketability. The primary basis for  arriving
at  such valuation  will be commonly  employed  valuation  multiples of selected
non-prescription  consumer  health  care  product  businesses  generally  deemed
comparable to such business.
 
     'Governing  Board' shall mean,  in respect of any  JV Entity, the Governing

Agreement and the other Operative Documents.

correspondence with appropriate regulatory agencies (registrations and licenses,
regulatory drug lists, advertising and promotion documents) adverse event files,
complaint files and manufacturing records.
 
     'Launch Date' shall mean, in respect of  any JV Product, the date of  first
sale  of that product  by the relevant JV  Entity for use  or consumption by the
general public  (other  than  sales resulting  from  regional  test  marketing);
provided, that if such date is not the first day of a calendar month, the Launch
Date shall mean the first day of the next following calendar month.
 
     'License  Agreements' shall mean the license agreements  among the Parties,

is not resolved within 45 calendar  days of the Governing Board meeting at which
such Deadlock arose, then, unless the relevant Governing Board otherwise agrees,
no  action will be taken with respect to  the matter which is the subject of the
Deadlock. In  the  event  that  the Deadlock  relates  to  any  proposed  Annual
Operating  Plan, then the relevant  JV Business will continue  to be operated on
the basis of the Annual Operating  Plan last approved by the relevant  Governing
Board.
 
     SECTION  3.07. Subcommittees of the  Governing Boards. Each Governing Board
may establish one or more subcommittees  to advise it on such specific  projects
or  matters as shall be  requested by the relevant Governing  Board or to act on
such projects  or  matters as  shall  be delegated  by  action of  the  relevant
Governing Board to such subcommittees; provided, however, that representation of
each of the W-L Participant and the Glaxo Participant on each subcommittee shall
be  equal.  Subcommittees shall  conduct  their business  on  such terms  as the
relevant Governing Board may determine.
 
     SECTION 3.08. Development Committees.  (a) Each JV  Entity may establish  a
committee  to  coordinate  the  development  activities  undertaken  by  the W-L
Participant, the Glaxo Participant or their respective Affiliates in  connection
with  the  business of  the  JV Entity  (each  a 'Development  Committee'). Each
Development Committee  shall  consist  of  eight members.  In  respect  of  each
Development  Committee, the W-L Participant and  the Glaxo Participant shall, by
written notice to the other, designate four individuals each to serve as members
on that committee.  Notwithstanding any Permitted  Transfer pursuant to  Section
12.02(a),  all such  individuals appointed by  the W-L Participant  or the Glaxo
Participant shall be directors, officers or senior employees of W-L or Glaxo, as
the case may be, or their respective Affiliates (excluding, in the case of  W-L,
W-WCHP).  In the event of  the removal, resignation or  death of any member, the
vacancy  thereby  created  shall  be  filled,  by  written  notice  to  the  W-L
Participant or the Glaxo Participant, as the case may be, by the participant who
designated  the  member  so  removed, resigning  or  deceased.  Each Development
Committee shall conduct  its business as  it sees  fit and shall  report to  the
relevant  Governing Board  on a  regular basis  or as  that Governing  Board may
direct. Each Development  Committee shall  have only  those powers  to bind  the
relevant  JV Entity as the  Governing Board of that JV  Entity may grant it, and
such Governing Board shall have absolute discretion as to whether to accept  and
follow any reports or recommendations submitted by the Development Committee.
 
     (b)  At  reasonable intervals,  and  in any  event  at least  once  in each
calendar year, each  Development Committee  shall meet to  discuss and  identify
potential  Glaxo OTC  Switch Products  or Ranitidine  Products for  the relevant
country and shall prepare and present  to the relevant Governing Board a  report
thereon, and the Parties shall consult and cooperate fully with each Development
Committee in respect of such process; provided, however, that Glaxo shall not be
required  to offer any OTC Switch Product or Ranitidine Product to any JV Entity
except pursuant to the provisions of Article V.
 
     SECTION 3.09. Removal of Representatives. In respect of any JV Entity,  the
W-L  Participant and the Glaxo Participant may at any time, by written notice to
the other, remove  (with or without  cause) one or  more of the  members of  the
Governing   Board,  any  subcommittee  thereof   or  the  Development  Committee
designated by it  and may, by  like notice,  designate new members  to serve  in
their place.
 
     SECTION  3.10.  No Remuneration.  Unless  the Parties  otherwise  agree, no
Person shall be entitled  to any fee, remuneration  or compensation from any  JV
Entity  in connection with their serving as a member of any Governing Board, any
subcommittee thereof or any Development Committee.
 
     SECTION 3.11. Other Positions of Representatives. Any Person may act in one
or more of the capacities of Representative, Alternate Representative, member of
any subcommittee or of any  Development Committee or officer, director,  manager
or  employee  of any  JV Entity  or any  Party  or any  Affiliate of  any Party,
notwithstanding that they act in any other such capacity.
 
     SECTION 3.12. Annual Operating Plan. The W-L Participant in each JV  Entity
shall  cause to be submitted to the Governing Board of that JV Entity, not later
than December 1 (or such other date as the Parties may agree) in each year,  for
review  and approval, an annual operating plan for the forthcoming calendar year
covering, among other  things, projections  and budgets with  respect to  sales,
 
                                       9
 

operating  and capital  expenditures, financing,  development and  marketing (in
respect of each JV  Entity, as so reviewed  and approved, the 'Annual  Operating
Plan'); provided,  however, that Glaxo shall cause the proposed Annual Operating
Plan in respect of the U.S. Partnership for the calendar year ending on December
31,  1994,  an  outline  draft  of  which is  identified  as  Exhibit  B  in the
Supplemental Document Package,  to be submitted  by Glaxo OTC  to the  Governing
Board  of the U.S. Partnership  as promptly as practicable  after the Closing of
this Agreement.
 
     SECTION 3.13. Funding.  W-L and  Glaxo hereby  agree to  contribute, or  to
cause  the W-L  Participant or  the Glaxo  Participant, as  the case  may be, to
contribute, in  accordance  with and  subject  to sound  commercial  principles,
equally (or as the Parties or such participants may otherwise agree), such funds
as  may be  necessary for the  conduct of  the relevant JV  Business whether for
working capital  or  capital expenditures.  All  such funds  shall,  unless  the
Parties  otherwise agree, be contributed to the relevant JV Entity as additional
equity.
 
     SECTION 3.14.  Deliberations. The  deliberations of  each Governing  Board,
Development  Committee and  each subcommittee  thereof shall  not extend  to any
business activity of the Parties other than as may be necessary to perform their
responsibilities in connection with the relevant JV Business.
 
     SECTION 3.15. Reserved Matters. Notwithstanding any other provision of this
Agreement or the other Operative Documents,  and without prejudice to any  other
such provision requiring the consent or agreement of both Parties, the following
matters shall be subject to the agreement of both Parties:
 
          (a) expansion of the JV Business into any new country; and
 
          (b)  all prices for the sale of  products between, or the provision of
     services by either of, the Parties (or their Affiliates), on the one  hand,
     and  any  JV Entity,  on the  other hand,  or  between any  two or  more JV
     Entities, with respect to the JV Businesses.
 
                                   ARTICLE IV
                            OPERATIONS; JV ENTITIES
 
     SECTION 4.01. General. The businesses  contemplated  by this Agreement  and
by  the other  Operative Documents  shall be  implemented by  JV Entities  to be
established from time to time by the Parties in accordance with this Agreement.
 
     SECTION 4.02. Establishment of Other JV Entities. Following (i)  acceptance
by W-L, on behalf of the relevant JV Entity (formed or to be formed), of a Glaxo
Offer  pursuant  to  Section 5.03, or  (ii) the making  by W-L of  a JV Election
pursuant to Section 5.04(b), the Parties shall, if necessary, promptly establish
a JV Entity in the relevant Non-U.S. Country in order to conduct the JV Business
which is the  subject of  such acceptance or  election in  accordance with  this
Article  IV (unless, taking  into account all  relevant  matters including those
set forth in  Section 4.03(a), the  Parties agree  that a JV  Entity in  another
country should conduct such business).
 
     SECTION 4.03. Form and Structure of JV Entities. The Parties agree that:
 
          (a)  the nature  of the  entity constituting  each JV  Entity shall be
     determined  by  the  Parties   taking  into  consideration  relevant   tax,
     accounting and legal issues;
 
          (b)  subject to Article XII, the  equity of the U.S. Partnership shall
     be owned  by  W-L  and  Glaxo  OTC  in  the  proportions  provided  in  the
     Partnership Agreement;
 
          (c)  subject to Article XII, the equity  of each other JV Entity shall
     be owned equally by  W-L (or such  of its direct  or indirect wholly  owned
     Affiliates,  or  W-WCHP  provided  the requirements  set  forth  in Section
     12.02(b) are satisfied,  as W-L  may nominate) and  Glaxo (or  such of  its
     direct  or indirect  wholly owned  Affiliates as  Glaxo may  nominate) and,
     subject to such principle, the  Parties shall use their reasonable  efforts
     to  organize  each such  entity  in such  manner as  will  permit it  to be
     classified for  U.S.  Federal  income  tax purposes  as  a  partnership  or
     otherwise  permit it to avoid being  classified as an 'uncontrolled Section
     902 corporation'  with  respect  to  W-L  within  the  meaning  of  Section
     904(d)(2)(E)(i) of the Internal Revenue Code of 1986, as amended; provided,
     however,  that such action shall not,  in Glaxo's reasonable judgment, have
     an adverse financial effect on Glaxo or any of its Affiliates;
 
                                       10
 

          (d) the Operating Profit and Loss with respect to each JV Entity shall
     be shared  equally  by  the  Parties,  and,  to  the  extent  necessary  or
     appropriate  to achieve  that objective, adjustments  shall be  made to the
     interests of the W-L Participant and the Glaxo Participant in the profit or
     loss of the JV Entity so as to  take into account any amounts in excess  of
     Fully  Allocated Cost realized  by either Party (or  any of its Affiliates)
     from the supply  of goods or  services to, or  use of property  by, the  JV
     Entity,  other than the charges provided  for in Sections 5.06, 6.01, 6.02,
     6.03 and 6.04, and after off setting such amounts by any fees, commissions,
     allowances or other payments  made pursuant to Section  6.05 in respect  of
     such supply of goods or services, or use of property, by such Party (or any
     of  its Affiliates). In addition, to  the extent necessary to fully achieve
     this objective, such  adjustments as are  necessary shall be  made to  such
     amounts, fees, commissions, allowances or other payments;
 
          (e)  the amounts to be charged by  the Parties and their Affiliates to
     each JV Entity in respect of management fees and royalty payments shall  be
     determined  in accordance with  Sections 5.06(d)  and 6.04 except that such
     amounts, with  respect to  the  U.S. Partnership,  shall be  determined  in
     accordance with Sections 5.06(c) and 6.03; and
 
          (f)  the membership of all statutory or legal governing bodies of each
     JV Entity shall be kept to the minimum permitted by all applicable laws (or
     as  the  relevant  Governing  Board  may  otherwise  determine);  provided,
     however,  that the relevant W-L Participant  and Glaxo Participant shall be
     equally represented on each such governing body.
 
     SECTION  4.04.  Management  of  JV  Entities.  The  W-L  Participant  shall
nominate,  subject to the  approval of the relevant  Governing Board pursuant to
Section 3.03(e), a General  Manager of each JV  Entity who will have  day-to-day
operational responsibility for such JV Entity (each a 'General Manager').
 
     SECTION  4.05.  Operations  To  Be  Conducted  in  Accordance  with  Annual
Operating Plan and Direction  of Governing Board.  The day-to-day operations  of
each  JV Entity shall be conducted by its General Manager in accordance with the
Annual Operating Plan  and otherwise in  accordance with the  directions of  the
relevant  Governing Board.  For the avoidance  of doubt, the  Parties agree that
none of the actions and matters referred  to in Sections 3.03 and 3.15 shall  be
taken  without the prior consent of the relevant Governing Board or the Parties,
as the case may  be, and the  Parties shall ensure that  the General Manager  of
each  JV Entity is fully  aware of the actions  which require such prior consent
and that his or her  authority does not extend  to such transactions or  matters
and shall ensure that the General Manager does not take any such actions.
 
                                   ARTICLE V
                                  JV PRODUCTS
 
     SECTION  5.01. General. Except as provided by this Article V, Glaxo and its
Affiliates shall be free to develop, manufacture, market, sell or distribute any
products in any country.
 
     SECTION 5.02. Ranitidine Products in the United States. (a) At the  Closing
of  this Agreement  W-L shall,  and Glaxo shall  cause Glaxo  OTC to, establish,
pursuant to the Partnership Agreement, the U.S. Partnership for the purposes  of
developing,  manufacturing, marketing,  selling and  distributing Ranitidine OTC
Products in the United States.
 
     (b) Glaxo may, in its sole discretion, from time to time offer to grant  to
W-L  on behalf of  the U.S. Partnership the  marketing, selling and distribution
rights (and, if  the Parties  agree, the development  and manufacturing  rights)
with  respect to Other  Ranitidine Products in  the United States.  In the event
that Glaxo decides, in its sole discretion, to offer to the U.S. Partnership the
rights to any  such product, Glaxo  shall offer,  by written notice  to W-L,  to
grant  to the U.S.  Partnership the exclusive right  (subject to Section 5.05(a)
and as provided  by the Sandoz  Agreement) to market,  sell and distribute  such
product  in  the  United States  (and,  if  the Parties  agree,  to  develop and
manufacture such product therefor) and to  grant the U.S. Partnership a  license
in  accordance with Section 5.06(a) and (b)  in respect thereof, in each case in
consideration for  the  royalties  payable  in respect  of  the  license  to  be
negotiated  in accordance with  Section 5.06(d) and  it shall be  a term of such
offer that W-L shall be
 
                                       11
 

entitled to provide  the U.S. Partnership  with services, and  to be  reimbursed
therefor, in each case in accordance with Section 6.04.
 
     (c)  Following the making of an  offer in accordance  with Section 5.02(b),
W-L shall as soon as reasonably practicable  and in any event within six  months
either accept or decline such offer on behalf of the U.S. Partnership by written
notice to Glaxo, and:
 
          (i)  Glaxo shall, during such six  month period, provide W-L with such
     further information relating to the matters  which are the subject of  such
     offer  (including copies of all  Glaxo Regulatory Documentation relating to
     the relevant  product  which is  the  subject of  such  offer) as  W-L  may
     reasonably  request and shall update such information promptly from time to
     time;
 
          (ii) in the event of such offer being accepted by W-L, W-L, on  behalf
     of  the  U.S.  Partnership,  and  Glaxo shall  use  their  best  efforts to
     negotiate and execute as  soon as reasonably practicable  and in any  event
     within  three months the relevant Operative  Documents (to be in accordance
     with the  principles  referred  to  in  Section  5.03(b),  Article  VI  and
     otherwise as the Parties may agree); and
 
          (iii)  in the event of such offer being declined by W-L, W-L on behalf
     of the U.S. Partnership,  shall at the time  the offer is declined  provide
     Glaxo  with a full statement of reasons  for declining such offer and shall
     afford Glaxo the opportunity of discussing fully such reasons for refusal.
 
     (d) Except as  provided by  Section 5.05(a) or  as provided  by the  Sandoz
Agreement, Glaxo shall not, and shall ensure that its Affiliates do not, market,
sell  or distribute  or  grant any license  or other similar  right to any Third
Party to market, sell or distribute any Ranitidine Product in the United States.
 
     SECTION 5.03. Other  Products and/or  Other Countries.  (a) General.  Glaxo
may,  in its sole discretion,  from time to time  offer to W-L to  grant to a JV
Entity or  Entities  (formed  or to  be  formed)  in a  particular  country  the
marketing,  selling  and distribution  rights (and,  if  the Parties  agree, the
development and manufacturing  rights) with respect  to a particular  Ranitidine
Product in a Non-U.S. Country or any OTC Switch Product.
 
     (b) The Glaxo Offer. If Glaxo desires to grant to any Third Party any right
to market, sell or distribute:
 
          (i)  any Ranitidine  Product in  any Non-U.S.  Country other  than the
     countries set forth on Schedule  5.03(b)(i) (the 'Specified Countries')  or
     under  the terms, as at  the date of this  Agreement, of the agreements set
     forth on Schedule 5.03(d); or
 
          (ii) any OTC Switch  Product in any country  other than the  Specified
     Countries;
 
Glaxo  shall offer, by written notice to W-L  (the 'Glaxo Offer'), to grant to a
JV Entity or Entities (formed or to  be formed) the exclusive right (subject  to
Section  5.05(a)) to  market, sell and  distribute such product  in the relevant
country (and, if  the Parties agree,  to develop and  manufacture  such  product
therefor)  and to grant such JV Entity  or Entities a license in accordance with
Section 5.06(a) and (b)  in respect thereof, in  each case in consideration  for
the  royalties payable in respect of the  license to be negotiated in accordance
with Sections 5.06(d) and  it shall be a  term of such offer  that W-L shall  be
entitled  to provide the relevant JV Entity or Entities with services, and to be
reimbursed therefor, in  each case  in accordance with  Section 6.04;  provided,
however,  that no Glaxo Offer shall be required to be made, and the restrictions
in Sections 5.03(d) and 5.04 hereof shall not apply, if:
 
          (x) at the time that a Glaxo  Offer would be required to be made  (or,
     if Section 5.04(a)(ii) is applicable, at the time that a Glaxo Notice would
     be  required to be made) W-L or any of its Affiliates or any Third Party on
     their behalf  (other than  pursuant to  a license  under which  W-L or  its
     Affiliates  are only entitled to receive  royalties and otherwise only have
     rights  consistent  with  passive  license  arrangements)  are  developing,
     manufacturing, marketing, selling or distributing (or have entered into any
     agreement,  other than such a license, to  do the same with respect to) any
     non-prescription product  in such  country which  would in  the  reasonable
     opinion of Glaxo directly compete with the Ranitidine Product or OTC Switch
     Product  which is the subject of the Glaxo Offer or the Glaxo Notice as the
     case may be, it being agreed by the Parties that a non-prescription product
     will directly compete with a Ranitidine OTC Product only if it contains  an
     H2  antagonist or a proton  pump inhibitor and except  as aforesaid, if the
     Parties cannot agree whether any such
 
                                       12
 

     non-prescription product will directly compete with a Ranitidine Product or
     an  OTC  Switch Product  the Parties  shall  seek to  resolve the  issue by
     negotiation; and
 
          (y) Glaxo shall have notified W-L  in writing that a Glaxo Offer  (or,
     if Section 5.04(a)(ii) is applicable, a Glaxo Notice) would be made but for
     the  terms  of  paragraph  (x)  of this  proviso  and  W-L  shall  not have
     undertaken in writing  to Glaxo,  within three  months of  receipt of  such
     written  notice,  to terminate  the development,  manufacturing, marketing,
     sale or distribution of any such competing product prior to the Launch Date
     for the relevant Ranitidine Product or OTC Switch Product.
 
     (c) Acceptance of Glaxo Offer. Following  the making of a Glaxo Offer,  W-L
shall  as soon as  reasonably practicable, and  in any event  within six months,
either accept or  decline such  offer on  behalf of  the relevant  JV Entity  or
Entities by written notice to Glaxo, and:
 
          (i)  Glaxo shall, during such six-month  period, provide W-L with such
     further information relating to  the matters which are  the subject of  the
     Glaxo  Offer  (including  copies  of  all  Glaxo  Regulatory  Documentation
     relating to the relevant product which  is the subject of the Glaxo  Offer)
     as  W-L may reasonably  request and shall  update such information promptly
     from time to time; and
 
          (ii) in the event of  the Glaxo Offer being  accepted by W-L, W-L  and
     Glaxo  shall use  their best  efforts to negotiate  and execute  as soon as
     reasonably practicable, and in any event within three months, the  relevant
     Operative Documents (to be in accordance with the principles referred to in
     Section 5.03(b), Article VI and otherwise as the Parties may agree); or
 
          (iii)  in the event  of the Glaxo  Offer being declined,  or not being
     accepted by  W-L  within  six months  of  the  Glaxo Offer,  Glaxo  or  its
     Affiliates  shall then, and only  then, be entitled to  grant a license, on
     terms no more  favorable than those  last offered to  W-L pursuant to  this
     Section  5.03, to  a Third Party  to develop, manufacture,  market, sell or
     distribute the  product which  is the  subject of  the Glaxo  Offer in  the
     country referred to therein.
 
     (d)  Restrictions  on Glaxo  and Glaxo  Affiliates.  Except as  provided in
Section 5.05(a) or under  the terms, as  at the date of  this Agreement, of  the
agreements  set forth on Schedule 5.03(d), Glaxo shall not and shall ensure that
its Affiliates do not  themselves market, sell or  distribute without the  prior
written  consent of W-L, and, except as further provided in Section 5.03(c)(iii)
and Section 5.04, Glaxo shall  not and shall ensure  that its Affiliates do  not
grant  any  license or  other similar  right to  any Third  Party any  rights to
market, sell or distribute:
 
          (i) any  Ranitidine Product  in any  Non-U.S. Country  other than  the
     Specified Countries; or
 
          (ii)  any OTC Switch  Product in any country  other than the Specified
     Countries;
 
          SECTION 5.04. Right of First Refusal. (a) The Glaxo Notice. If:
 
          (i) following the making of a Glaxo Offer which is not accepted by W-L
     pursuant to Section  5.03(c), Glaxo  desires to grant  pursuant to  Section
     5.03(c)(iii) to any Third Party the right to market, sell or distribute the
     products  which are the subject of the  Glaxo Offer in the country referred
     to in the Glaxo Offer  on terms more favorable  than those last offered  to
     W-L pursuant to Section 5.03; or
 
          (ii)  Glaxo desires to grant  a license to any  Third Party to market,
     sell or distribute  any Ranitidine  Product or  OTC Switch  Product in  any
     Specified Country;
 
Glaxo shall first give written notice (the 'Glaxo Notice') to W-L specifying the
relevant country ('Relevant Country'), a description of the products intended to
be  marketed in such country and in respect of which such license is intended to
be granted and  the principal  terms on  which such  license is  proposed to  be
granted and Glaxo shall, and shall ensure that its Affiliates, only grant such a
license if permitted to do so by Section 5.04(d).
 
     (b)  The JV Election. W-L  shall as soon as  reasonably practicable, and in
any event within one month of receipt of a Glaxo Notice (if the Glaxo Notice  is
given  pursuant to  Section 5.04(a)(i))  or three months  of receipt  of a Glaxo
Notice (if the Glaxo Notice is given pursuant to Section 5.04(a)(ii)), by notice
in writing to Glaxo, either elect  that the marketing, sale and distribution  of
the  products specified  in the  Glaxo Notice in  the Relevant  Country shall be
exclusively conducted by a JV Entity (the 'JV
 
                                       13
 

Election') or waive its right to make such an election. Following the making  of
a JV Election, the Parties shall use their best efforts to negotiate and execute
as  soon  as  reasonably practicable,  and  in  any event  within  three months,
Operative Documents having  the same principal  terms as those  proposed in  the
Glaxo Notice and otherwise as W-L and Glaxo shall agree.
 
     (c)  Information.  Following the  giving of  a  Glaxo Notice,  Glaxo shall,
during the  period in  which W-L  may make  a JV  Election pursuant  to  Section
5.04(b)  but has not done so or waived its right to do so, provide W-L with such
further information  relating to  the matters  required to  be included  therein
(including copies of all Glaxo Regulatory Documentation relating to the relevant
product  which is the subject of the Glaxo Notice) as W-L may reasonably request
and shall update such information promptly from time to time.
 
     (d) Glaxo's Rights If No JV Election. If W-L shall waive its right to  make
a  JV Election in accordance with Section 5.04(b) or, in any event, if following
the expiry of the one or three  month period referred to in Section 5.04(b)  W-L
shall not have made a JV Election, Glaxo and its Affiliates shall then, and only
then, be free to license (on terms no more favorable than those set forth in the
Glaxo  Notice)  the  marketing, sale  and  distribution rights  to  the products
specified in the Glaxo Notice in  the Relevant Country; provided, however,  that
such  marketing, selling or distribution commences  within two years of (x) such
waiver or (y) the expiry of such one or three month period, as the case may  be,
or  such longer  period as  may be  necessary solely  because of  any regulatory
delays not attributable to any omission,  negligence or otherwise due to a  lack
of reasonable diligence by Glaxo or the proposed licensee.
 
     SECTION  5.05. Glaxo Marketing Rights. (a) Notwithstanding anything in this
Article V to the contrary, Glaxo, any direct or indirect wholly owned  Affiliate
of  Glaxo, any  Affiliate set  forth on Schedule  5.05(a) hereof  and any future
Affiliate of Glaxo which is not a wholly owned Affiliate of Glaxo and which  has
not  been established and is not being used for the purpose of circumventing the
restrictions of  this  Agreement on  the  grant of  licenses  by Glaxo  and  its
Affiliates  to Third Parties (all  such Affiliates being 'Permitted Affiliates')
shall each be free to itself market, sell or distribute in the United States  or
in  any Non-U.S. Country, a  version of a drug  product (the 'Relevant Product')
having the same indications or dosage  strength as a then existing  Prescription
Product  of  Glaxo  or its  Affiliates  marketed  in the  relevant  country (the
'Relevant Prescription  Product')  if  the  Relevant Product  is  given  an  OTC
Classification in the relevant country and provided, however, that:
 
          (i) Glaxo shall first have given written notice (a 'Marketing Notice')
     to  W-L of  its intention  so to  market, sell  or distribute  the Relevant
     Product, giving details of the Relevant Product including its  indications,
     dosage  strength, brand names,  tradenames and trademarks  and the relevant
     country (the 'Glaxo Relevant Country') not less than 90 calendar days prior
     to the commencement of such marketing, selling or distribution;
 
          (ii) such marketing, sale or distribution shall not involve the use of
     Mass Media directed to consumers unless, in the Glaxo Relevant Country, use
     of Mass Media with  respect to the Relevant  Prescription Product has  been
     lawfully  carried  out by  Glaxo or  its Affiliates  prior to  the Relevant
     Product being given an OTC Classification  in that country and such use  of
     Mass   Media  was  not  carried  out  with  the  purpose  of  avoiding  the
     restrictions of  this paragraph  (ii);  for the  purposes of  this  Section
     5.05(a)(ii) and Section 5.05(b), 'Mass Media' shall mean television, radio,
     outdoor advertising, direct mail or lay newspapers, magazines or journals;
 
          (iii)  in the event that a JV Entity has begun developing a Ranitidine
     Product (if the Relevant Product is a Ranitidine Product) or (in any  other
     case)  a product  containing the same  principal active  ingredients as the
     Relevant  Product   ('Comparable   Products')  for   marketing,   sale   or
     distribution  in the  Glaxo Relevant Country  but has  not begun marketing,
     selling or distributing the Comparable Product in such country:
 
             (A) W-L and  Glaxo shall  discuss in  good faith  the viability  of
        developing or continuing to develop a Ranitidine Product or a Comparable
        Product, as the case may be, for marketing, sale or distribution by a JV
        Entity  in  the Glaxo  Relevant Country  and/or  the establishment  of a
        co-promotion or co-marketing arrangement with respect to the  marketing,
        sale  or  distribution of  the Relevant  Product  in the  Glaxo Relevant
        Country,
 
                                       14
 

             (B) if the Parties fail  to agree on satisfactory arrangements  for
        such development of a Ranitidine Product or a Comparable Product or such
        a  co-promotion or co-marketing arrangement with respect to the Relevant
        Product, Glaxo shall first have  reimbursed, on an after-tax basis,  (X)
        all  relevant JV Entities  and/or W-L and the  W-L Participant (with the
        principle being that W-L and the W-L Participant be made whole) for  all
        costs  (including reimbursement costs)  expended or incurred  by them or
        for which they are, or will with  the passage of time become, liable  in
        connection  with the  development of  Ranitidine Products  or Comparable
        Products, as  the  case may  be,  specifically for  marketing,  sale  or
        distribution  in the  Glaxo Relevant  Country and  (Y) if  the Marketing
        Notice relates to Ranitidine Products in the United States, W-L for  all
        milestone  payments made by W-L to Glaxo Inc. pursuant to the Ranitidine
        Rights Agreement, and
 
             (C) immediately following  the reimbursement  of development  costs
        and,  if relevant, milestone payments in respect of any product pursuant
        to clause (B) above, any license granted to any JV Entity in respect  of
        such product shall terminate without further action of the Parties;
 
          (iv)  in the  event that a  JV Entity shall  have commenced marketing,
     selling or distributing Ranitidine Products  (if the Relevant Product is  a
     Ranitidine  Product) or  a Comparable  Product (in  any other  case) in the
     Glaxo Relevant Country, and without prejudice to Glaxo's and its  Permitted
     Affiliates'  rights to market,  sell or distribute  the Relevant Product in
     the Relevant Country,  W-L and Glaxo  shall discuss and  negotiate in  good
     faith  arrangements with respect to the marketing, sale and distribution of
     the Relevant Product and the relevant Ranitidine Product or the  Comparable
     Product,  as the case may  be, in the Glaxo  Relevant Country including the
     establishment of co-promotion or co-marketing arrangements with respect  to
     such products; and
 
          (v)  in the  event that  a JV  Entity shall  have commenced marketing,
     selling or distributing Ranitidine Products  (if the Relevant Product is  a
     Ranitidine  Product)  or  Comparable  Products  (in  any  other  case), the
     Relevant Product shall only be marketed,  sold or distributed (by Glaxo  or
     its Permitted Affiliates) under trademarks, trade dress, brand marks, brand
     names  and logos being used by Glaxo  or its Affiliates in respect of their
     prescription business in the Relevant Country as it relates to the Relevant
     Prescription Product or  such other trademarks,  trade dress, brand  marks,
     brand  names or logos which are different than, and not confusingly similar
     to, those granted to the JV Entity.
 
     (b) In the event that Glaxo intends that it or any Permitted Affiliate will
market, sell or distribute any Relevant Product pursuant to Section 5.05(a)  and
such  product would be suitable for promotion by Mass Media but is not permitted
to be so promoted by  Section 5.05(a)(ii), W-L and  Glaxo shall discuss in  good
faith   the  desirability   of  establishing  a   co-promotion  or  co-marketing
arrangement in respect of that product.
 
     (c) For the avoidance of doubt, the provisions of this Section 5.05 do  not
in  any way apply to or restrict the marketing, selling or distribution by Glaxo
or any of its Affiliates on or after the date of this Agreement in any Specified
Country except to the extent that a JV Entity is developing, marketing,  selling
or  distributing an OTC version of the Relevant Prescription Product in any such
Specified Country.
 
     SECTION 5.06. Licenses and  Services. (a) Grant of  License. In respect  of
each  country where  any products are  to be  developed, manufactured, marketed,
sold or distributed  by a  JV Entity,  Glaxo shall  promptly on  request by  W-L
grant,  or  cause its  Affiliates  to grant,  to the  relevant  JV Entity  or JV
Entities an exclusive license (even as to  Glaxo and its Affiliates, but in  any
event  subject to Section 5.05(a) but subject  to the rights, if any, granted by
the terms,  as at  the date  hereof, of  the Agreements  set forth  on  Schedule
5.03(d) or the Sandoz Agreement):
 
          (i) to use, in the non-prescription health care market, all patent and
     other  intellectual property rights owned by Glaxo or any of its Affiliates
     as may be necessary for  the development, manufacture, marketing, sale  and
     distribution  of such products by or on behalf of the relevant JV Entity or
     JV Entities; and
 
                                       15
 

          (ii) where any such product is a Ranitidine Product, to use the Zantac
     Trademark (or, if  the Zantac Trademark  is not used  in that country,  the
     prescription  trademark  so  used  in  that  country)  in  connection  with
     Ranitidine Products  in  the non-prescription  health  care market  in  the
     relevant country; provided, however, that Glaxo shall not be required so to
     grant  or  to  cause  the grant  of  an  exclusive license  to  use  in the
     non-prescription health care  market the  Zantac Trademark  (or such  other
     prescription  trademark)  in  respect of  any  Non-U.S. Country  if  it can
     demonstrate, to  the  reasonable  satisfaction  of W-L  on  behalf  of  the
     relevant JV Entity (formed or to be formed), a compelling commercial reason
     why  such trademark should not  be used in such  Non-U.S. Country, in which
     case, Glaxo shall not itself use  the Zantac Trademark and shall not  grant
     to  any Person a license to use the Zantac Trademark in connection with the
     marketing, sale or distribution of  any Ranitidine Product in the  relevant
     Non-U.S. Country.
 
     (b)  Terms of License.  Each license shall  provide for the  payment by the
relevant JV Entities of royalties to  be determined in accordance with  Sections
5.06(c)  and  (d),  shall  continue until  terminated  in  accordance  with this
Agreement (under Section 5.05(a)(iii)(C) or Article XIV) and shall otherwise  be
on  such terms  as Glaxo  may in  good faith  offer to  W-L or  otherwise as the
Parties may agree; and provided, however, that unless Glaxo otherwise agrees, no
JV Entity shall promote, sample or  sell JV Products through marketing  channels
principally  targeted at physicians, other  medical practitioners or pharmacists
in the relevant country.
 
     (c) Royalties Payable by the U.S. Partnership in Respect of Ranitidine OTC.
The Parties  agree that  in  consideration for  the  grant, in  accordance  with
Sections  5.06(a) and (b), of a license by Glaxo Services to use patents and the
Zantac Trademark  in connection  with the  development, manufacture,  marketing,
sale  and distribution of  Ranitidine OTC and  Ranitidine OTC Products  in or in
respect of the United States, the U.S. Partnership and/or any other relevant  JV
Entities shall pay to Glaxo Services a royalty at the following rates:
 
          (i)  in  respect of  the  period beginning  on  the Launch  Date  of a
     Ranitidine OTC  Product  to  (but  not  including)  the  first  anniversary
     thereof,  15%  of  the  U.S.  Partnership's  Net  Sales  of  Ranitidine OTC
     Products;
 
          (ii) in  respect of  the period  beginning on  the date  of the  first
     anniversary  of such Launch Date to (but not including) the date upon which
     both  of  Glaxo's  U.S.  patents  (including  all  divisions,   extensions,
     reissues, renewals, continuations and continuations in part thereof) listed
     on  Schedule 5.06(c)(ii)  shall have  expired or  shall cease  to contain a
     Valid Claim (the 'Expiry Date'), 20% of the U.S. Partnership's Net Sales of
     Ranitidine OTC Products; and
 
          (iii) in respect of  the period beginning on  the Expiry Date, 15%  of
     the U.S. Partnership's Net Sales of Ranitidine OTC Products;
 
provided,  however,  that the  Parties shall  renegotiate,  in good  faith, such
royalty in the event that such royalty when aggregated with the Fully  Allocated
Cost  of  manufacturing (determined  in accordance  with Schedule  1.01(a)) bulk
Ranitidine supplied to  any JV Entity  in respect  of the business  of the  U.S.
Partnership  plus  the  Fully  Allocated  Cost  incurred  in  manufacturing  and
finishing Ranitidine OTC Products exceed, in respect of any twelve month period,
the amount representing the  percentage of the U.S.  Partnership's Net Sales  of
Ranitidine  OTC Products as follows:  (i) in respect of  the twelve month period
ending on  the day  preceding the  first anniversary  of the  Launch Date  of  a
Ranitidine  OTC  Product by  the U.S.  Partnership,  26% of  Net Sales;  (ii) in
respect of each  following twelve month  period, or part  thereof, prior to  the
Expiry  Date, 30% of  Net Sales; and  (iii) in respect  of each following twelve
month period ending on the day prior to the anniversary of the Launch Date of  a
Ranitidine  OTC Product by the U.S. Partnership, 26% of Net Sales; and provided,
further, that if  (following adjustments, if  any, made in  accordance with  the
foregoing  proviso) the U.S.  Partnership incurs a loss  (by reference to profit
before tax as  calculated in  accordance with United  States generally  accepted
accounting  principles) in the  twelve month period ending  on the day preceding
the second anniversary of such Launch  Date, the Parties shall discuss, in  good
faith, an adjustment to the royalty and the Management Fee.
 
     (d)  Other  Royalties. (i)  The royalties to be charged to the relevant  JV
Entities in respect of sales of  Ranitidine  OTC Products in Non-U.S.  Countries
shall, with regard to the trademarks and patents
 
                                       16
 

     licensed by Glaxo or its Affiliates to the relevant JV Entity or  Entities,
     be  broadly  similar  to  the trademark  and  patent  royalties  payable in
     respect  of sales  of such products in the United States in accordance with
     Section 5.06(c),  subject only  to such  changes or modifications  as Glaxo
     and  W-L may agree  are  necessary  to  reflect the relative  value of  the
     rights  being  granted  to the  JV  Entity or  Entities  and  local  market
     conditions.

         (ii) The royalties to be charged to all JV Entities (including the U.S.
     Partnership)  in respect  of Other  Ranitidine  Products  and  OTC   Switch
     Products  shall with  regard  to the  trademarks  and patents  licensed  by
     Glaxo  to  the relevant  JV Entity or  Entities, be such royalties as Glaxo
     may in good faith offer to W-L or otherwise as the Parties may agree.
 
     (e) Services. W-L shall be entitled to provide each JV Entity with services
and shall be entitled to be reimbursed therefor in accordance with Sections 6.03
and 6.04.
 
    SECTION 5.07. Representations and Warranties. With respect to any Ranitidine
Product or OTC Switch Product to be developed, marketed, sold or distributed  by
any  JV Entity pursuant to this Article V (other than Ranitidine OTC Products to
be developed, marketed, sold or distributed by the U.S. Partnership pursuant  to
Section  5.02(a)), Glaxo shall deliver to W-L  and the relevant JV Entity on the
date of  execution of  the relevant  JV Implementation  Agreement (if  a new  JV
Entity  is being  established) or the  relevant License Agreement  (in any other
case), a  certificate confirming  that the  representations and  warranties  set
forth  in Sections 10.02(b), 10.04 to 10.07 and 10.09 are true and correct as at
the date of such  certificate subject only to  such exceptions thereto as  Glaxo
may  detail  in such  certificate  (such exceptions  to  be limited  to specific
factual matters); provided, however, that:
 
          (a) for the purposes of  such certificate and the representations  and
     warranties made therein, references to 'Glaxo Products' as used in Sections
     10.02(b),  10.04  to 10.07  and 10.09  shall  mean the  relevant Ranitidine
     Product or OTC Switch Product to be developed, manufactured, marketed, sold
     or distributed by the relevant JV Entity in the relevant country;
 
          (b) where the participant in the relevant JV Entity is not a Party but
     is an Affiliate of a Party, such representations and warranties shall,  for
     the purposes of this Section 5.07, be construed as if references therein to
     such  Party were references  to both that  Party and the  Affiliate of such
     Party which is the participant in the relevant JV Entity; and
 
          (c) references therein to the  'Glaxo Relevant Agreements' shall  mean
     the  JV Implementation Agreement (if a  new JV Entity is being established)
     or the relevant License  Agreement (in any other  case) in connection  with
     which  such representations and warranties  are being confirmed pursuant to
     this Section 5.07, and all other Operative Documents being entered into  in
     connection  therewith, in each case to which Glaxo or any of its Affiliates
     is a party.
 
     SECTION 5.08. Non-Compete. Except as expressly permitted by Article V, each
of W-L and Glaxo agrees that it will  not, and will cause its Affiliates not  to
introduce,   or  participate  in  the  introduction   of,  any  product  in  the
non-prescription consumer health care market  (other than a JV Product  pursuant
to  the terms of  this Agreement) in any  country if such  product would, in the
reasonable opinion of  the other  Party, directly  compete with  any JV  Product
being marketed, sold or distributed in that country, or which is being developed
for marketing, sale or distribution, by a JV Entity in such country. The Parties
agree that a product will directly compete with a Ranitidine OTC Product only if
it contains an H2 antagonist or a proton pump inhibitor. Except as aforesaid, if
the  Parties cannot agree  whether any product  will directly compete  with a JV
Product they shall seek to resolve the issue by negotiation.
 
     SECTION 5.09. Japan.  The provisions of  this Agreement do  not in any  way
apply  to or  restrict the  development, marketing,  selling or  distribution by
either Party (or their respective Affiliates) of any product in Japan.
 
                                   ARTICLE VI

and  Ranitidine OTC  Products, subject  to and as  set forth  in the Development
Agreement) that:
 
                                       17
 

          (a) development costs  in the  United States  shall be  funded as  set
     forth in the Partnership Agreement;
 
          (b)  subject  to  clause  (a)  above,  the  relevant  JV  Entity shall
     reimburse the Parties' and their Affiliates Fully Allocated Costs  incurred
     after  the  date  of  this  Agreement  in  respect  of  the  development of
     Ranitidine Products and the  development of OTC  Switch Products which  the
     Parties  have determined to develop in  connection with the business of any
     JV Entity;
 
          (c) all development  work in  respect of Ranitidine  Products and  OTC
     Switch  Products which the Parties have determined to develop in connection
     with the  business of  any JV  Entity  shall, following  the grant  of  NDA
     Approval,  in the case of the United States, or Regulatory Approval, in the
     case of  any Non-U.S.  Country, in  respect thereof,  be conducted  by  W-L
     CPR&D,  and W-L CPR&D shall  be reimbursed by the  relevant JV Entities its
     Fully Allocated Costs incurred in such development; and
 
          (d) amounts charged to any JV Entity in respect of the development  of
     JV  Products shall be  charged to the  relevant JV Entity  pursuant to this
     Section 6.01 taking  into account any  special credits or  any special  tax
     benefits  in excess of a deduction for 100% of the expenditure to which the
     Party making such charge  is entitled (other than  by flow-through of  such
     credit  or tax  benefit to  such Party  as a  partner or  owner of  such JV
     Entity) by virtue of the nature of the expenditure.
 
     SECTION 6.02. Ranitidine OTC; Ownership of NDA; Milestone Payments. Subject
to and as set forth in the Ranitidine Rights Agreement, the Parties agree that:
 
          (a) no NDA in respect of Ranitidine  OTC shall be submitted by any  of
     the  Parties or  any of  their Affiliates or  by any  JV Entity  to the FDA
     without the prior approval of the Governing Board of the U.S. Partnership;
 
          (b) at  the  Closing  of  this  Agreement  W-L  shall  acquire  a  50%
     beneficial  interest  in  the Ranitidine  Rights  owned by  Glaxo  Inc., in
     consideration of which W-L  shall pay to  Glaxo Inc. upon  each of (i)  the
     first  submission of  an NDA  in respect  of Ranitidine  OTC to  the FDA in
     accordance with Section 6.02(a) and (ii) NDA Approval thereof, a  milestone
     payment in each case in the amount of $2.666 million; and
 
          (c)  following the  acquisition referred to  in clause  (b) above, W-L
     shall contribute  its  interests  in  the Ranitidine  Rights  to  the  U.S.
     Partnership  and Glaxo Inc.  shall transfer its  interest in the Ranitidine
     Rights to  Glaxo OTC,  which shall  contribute such  interest to  the  U.S.
     Partnership.
 
     SECTION  6.03. Services To  Be Provided by  W-L to the  U.S. Partnership in
Respect of Ranitidine  OTC Products.  Subject to  and as  set forth  in the  W-L
Services  Agreement  the  Parties  agree that  in  respect  of  the development,
marketing, selling and distribution  by the U.S.  Partnership of Ranitidine  OTC
Products,  W-L shall provide the U.S. Partnership with the services set forth on
Schedule 6.03(a)  in  consideration  for  the  Fully  Allocated  Costs  of  such
services,  other than the services marked with an asterisk on such Schedule, and
an additional  fee  to be  calculated  as set  forth  on Schedule  6.03(b)  (the
aggregate  of  such  Fully  Allocated  Costs  and  such  fee  being  called  the
'Management Fee'); provided, however, that in respect of the provision by W-L to
the U.S.  Partnership  of the  services  referenced on  Schedule  6.03(a)  under
'General Administration' and 'Corporate Allocations' prior to the Launch Date of
a  Ranitidine OTC Product in the United States, W-L shall only be reimbursed its
Fully  Allocated  Costs  to  the  extent  such  costs  are  direct  and  readily
identifiable.
 
     SECTION  6.04. Other Services  To Be Provided  by W-L. With  respect to the
development, marketing, selling and distribution  by the U.S. Partnership of  JV
Products   (other  than  Ranitidine  OTC  Products)  and  with  respect  to  the
development, marketing,  selling  and distribution  of  all JV  Products  by  JV
Entities  (other than the U.S. Partnership), the Parties shall negotiate in good
faith the services to be provided by W-L to the U.S. Partnership or the relevant
JV Entity and any costs to be reimbursed, and fees to be paid, to W-L in respect
thereof. The Parties agree that such  services and related costs and fees  shall
be  broadly similar to the  services provided by W-L,  and the related costs and
fees receivable by W-L, pursuant to the W-L Services Agreement, subject to  such
changes as W-L and Glaxo agree are appropriate to reflect the cost to W-L of the
services to be provided by it and local market conditions.

     SECTION 6.05. Supply. (a) In order to protect their respective interests in
the License Agreements and to assure the uniform quality of Ranitidine Products,
the  Parties  agree  that, except  in  the  circumstances set  forth  in Section
6.05(b), all Ranitidine required for  the manufacture of Ranitidine Products  to
be  marketed,  sold or  distributed by  any  JV Entity  in accordance  with this
Agreement and  the  Operative  Documents  shall be  supplied  by  Glaxo  or  its
Affiliates  to the relevant JV  Entity or JV Entities at  prices to be agreed by
the Parties and, in consideration thereof, Glaxo or its Affiliates shall pay  to
such  JV  Entity  or  JV  Entities  or  to  W-L  or  its  Affiliates  such fees,
commissions, allowances or similar payments as the Parties shall determine.  All
other  compounds and/or related finished products  to be supplied by the Parties
or any of their Affiliates required for the manufacture of JV Products shall  be
supplied to the relevant JV Entity on terms to be negotiated.
 
     (b)  It shall be  a term of  all License Agreements  relating to Ranitidine
that, in the event  that Glaxo or  its Affiliates fail  to supply Ranitidine  in
accordance with Section 6.05(a) or the relevant Supply Agreement for a period of
three  months,  and for  so  long as  such failure  by  Glaxo or  its Affiliates
continues unbroken (except for periods of  four weeks or less), the relevant  JV
Entity   or  Entities  shall  be  entitled  to  conduct  bulk  manufacturing  of
Ranitidine.
 
     SECTION 6.06. Manufacture of JV  Products. Secondary manufacture from  base
compounds  (including tableting,  labeling and packaging)  of JV  Products to be
marketed, sold or distributed by a JV Entity shall take place at such sites  and
facilities  (including, without limitation,  facilities of the  Parties or their
Affiliates) as the Governing Board of the relevant JV Entity may determine.
 
     SECTION 6.07. Financial Information; Audit.  In respect of any matters  for
which the Parties, or their Affiliates, shall, under the terms of this Agreement
or  any of the other Operative Documents, be entitled to any payment from any JV
Entity ('Relevant  Matters'),  (i)  the  Parties shall  and  shall  cause  their
Affiliates  and the JV Entities to maintain  such books, accounts and records as
may be necessary to determine rights to such payment, (ii) the JV Entities shall
give the other Party, its Affiliates, any  relevant JV Entity and each of  their
respective  independent  accountants,  and  the  Parties  and  their  respective
Affiliates shall  give  the independent  accountants  of the  other  Party,  its
respective  Affiliates  and any  relevant JV  Entity, reasonable  access thereto
(after written notice not in any event  to be less than five Business Days,  and
in  the case  of independent accountants,  after execution  of a confidentiality

     Glaxo, none  of  the Glaxo  Rights  are  under threat  of  cancellation  or
     suspension  for  any reason  nor  is there  any  basis for  cancellation or
     suspension. The  Glaxo  Rights and  the  consummation of  the  transactions
     contemplated   by  the  Glaxo  Relevant  Agreements  do  not  infringe  any
     trademark, patent, trade name, copyright or other right of any Third Party.
     There are  no  unexpired patents  owned  by  a Third  Party  having  claims
     covering  any Glaxo  Products or covering  any method employed  by Glaxo in

     warning  by Glaxo or  any of its  Affiliates (past or  present), or, to the
     best of  Glaxo's knowledge,  any  investigation or  consideration  relating
     thereto.
 
          (b)  For purposes  of this Section  10.06 the  term 'Occurrence' shall
     mean any accident, happening or event  which is caused or allegedly  caused
     by  any alleged hazard or alleged  defect in manufacture, design, materials

     or  any breach  of express  or implied  warranties or  representations with
     respect to, or any such accident, happening or event otherwise involving, a
     Glaxo Product which  results or is  alleged to have  resulted in injury  or

     execution  and delivery of the Glaxo Relevant Agreements or the performance
     by Glaxo and its Affiliates of their obligations thereunder contemplated to
     be performed at the  date these representations  and warranties are  given,
     and Glaxo has no reason to believe that it or its Affiliates will be unable
     to  obtain  any Permits  which are  required for  the performance  of their
     future obligations thereunder except, in each case, where the failure to do
     so  would  not  have  a  materially  adverse  effect  on  the  transactions
     contemplated by the Glaxo Relevant Agreements.
 
          (b)  Except as set forth on Schedule 10.07, all of the Glaxo Products,

     similar  references,  shall  be  construed  to  mean  all  transactions  or
     obligations contemplated  by this  Agreement  (other than  transactions  or
     obligations contemplated by this Agreement which will arise under Operative
     Documents  other than  the Closing  Documents), each  of the  other Closing

     transactions contemplated  by  the  relevant  JV  Implementation  Agreement
     and/or other Operative Documents. In the event a government entity places a
     condition on its approval of the

        Entity; and
 
             (c) references in Articles IX and X to 'W-L Relevant Agreements' or

     each  Party  and their  respective  Affiliates necessary  to  authorize the
     execution, delivery  and  performance  of the  relevant  JV  Implementation
     Agreement  and/or other  Operative Documents,  and the  consummation of the
     transactions contemplated therein, shall have  been duly and validly  taken

     resolutions or other instruments authorizing the relevant JV Implementation
     Agreements and the  Operative Documents and  the transactions  contemplated
     therein.

any manner, all or any part of its individual interest in this Agreement, any of

writing by each of the other  Parties (in their sole discretion), with  specific
reference to this Section 12.01 or (ii) is
 
                                       26
 

otherwise permitted under this Article XII or Article XIV of this Agreement. For
the  avoidance of doubt, in this Article XII, references to 'transfer' shall not
include the appointment of any distributor.
 
     SECTION 12.02. Permitted Transfers. (a)  Nothing in this Article XII  shall
prevent the transfer:
 
          (i)  by any Party of all of its individual interest in this Agreement,
     any of the Operative Documents,  any JV Business or  any JV Entity if  such
     individual  interest is transferred to, and  for so long as such transferee
     is, a direct or  indirect wholly owned  Affiliate of W-L  or Glaxo, as  the
     case  may be, (or, in the case of W-L, if such transferee is W-WCHP and the
     requirements set forth in clause (b) below are satisfied); or
 
          (ii) by any Person to whom a  transfer is made pursuant to clause  (i)
     above  to W-L or Glaxo, as the case may  be, or to, and for so long as such
     Person is, a direct or indirect wholly owned Affiliate of W-L or Glaxo,  as
     the  case may be, (or, in the case of W-L, if such Person is W-WCHP and the
     requirements set forth in clause (b) below are satisfied);
 
provided, however, that:
 
          (v) notwithstanding the provisions of clause (x) below, following  any
     transfer  permitted by this Section 12.02(a), the references in clauses (i)
     and (ii)  above  to W-L  and  to Glaxo  shall  not be  construed  as  being
     references  to  any  Person  other  than  the  respective  parties  to this
     Agreement at the date hereof;
 
          (w) no transfer may be made  pursuant to this Section 12.02(a)  unless
     the  proposed transferee  shall have agreed  to assume,  by express written
     agreement with the  other Parties  (in form and  substance satisfactory  to
     them),  all of the obligations of the transferor in respect of the interest
     being transferred, and no such transfer shall relieve the transferor of its
     obligations under this Agreement or the Operative Documents or otherwise in
     respect of the JV Businesses and the JV Entities;
 
          (x) any  Person  to  whom  a  transfer is  made  pursuant  to  and  in
     accordance  with this  Section 12.02(a)  shall be  joined as  an additional
     party hereto and to the relevant Operative Documents and shall be deemed to
     have irrevocably covenanted with the other Parties hereto to transfer to  a
     Person  who is a  permitted transferee under  clauses (i) and  (ii) of this
     Section 12.02(a)  all of  its  interest in  this Agreement,  the  Operative
     Documents,  all JV Businesses and all JV Entities immediately prior to such
     Person ceasing to be such a permitted transferee;
 
          (y) not  less than  all of  a Party's  interest in  any particular  JV
     Entity may be transferred pursuant to this Section 12.02(a); and
 
          (z)  the Parties  may agree to  restrict such transfers  to the extent
     they deem necessary or appropriate to allow a JV Entity to be classified as
     a partnership for U.S. Federal income tax purposes.
 
     (b) W-L shall only be  able to exercise its  rights with respect to  W-WCHP
under  Section 4.03(c)  and Section  12.02(a)(i) and (ii)  if, (x)  W-L holds or
controls a majority of the votes  exercisable on the Governing Board of  W-WCHP,
(y)  W-L has sole authority to exercise  the rights to be exercised hereunder or
under the Operative Documents or in relation hereto or thereto and (z) no Person
other than W-L,  Wellcome plc or  their respective Affiliates  holds any  equity
interest in W-WCHP.
 
     (c)  Notwithstanding the terms of this Section 12.02 and the ability of the
Parties to make Permitted Transfers hereunder, the Parties hereby agree that, if
the terms of this Section 12.02 have disadvantageous tax consequences to one  or
both  of the Parties in respect  of its or their interest  in any JV Entity, the
Parties shall negotiate  with each  other in  good faith  modifications to  this
Section 12.02 insofar as it applies to such JV Entity.
 
     SECTION  12.03. Change of Control. (a) In  the event that (i) a Third Party
acquires beneficial ownership (as  defined below) of 30%  or more of the  voting
capital  of either Glaxo on the one hand or W-L on the other hand (the 'Affected
Party') or, in the event that  all or any part of  W-L's JV Interest is held  by
W-WCHP,  either (ii) W-L ceases at any time to hold or control a majority of the
votes exercisable on the governing board of W-WCHP, or (iii) W-L ceases to  have
sole  authority to exercise  the rights to  be exercised hereunder  or under the
Operative Documents or in  relation hereto or thereto  or (iv) any Person  other
than  W-L, Wellcome plc or their respective Affiliates holds any equity interest
 
                                       27
 

in W-WCHP ('Change of  Control'), then W-L  or Glaxo (as the  case may be)  (the
'Non-Affected  Party') shall, if it  believes in good faith  that such Change of
Control is prejudicial  to such  Affected Party's  JV Interest,  have the  right
within  30  calendar days  following  receipt of  written  notice of,  or public
announcement of, the occurrence of  the Change in Control  at its option and  in
its  sole and absolute  discretion by written  notice (the 'Acquisition Notice')
either:
 
          (x) to require the Affected Party to, and to cause its Affiliates  to,
     sell,  transfer  and convey  the  whole of  the  Affected Party's  and such
     Affiliates' equity interest in all  JV Entities (together the 'JV  Equity')
     (or  if the change  of control arises  under clause (ii),  (iii) or (iv) of
     Section 12.03(a), such of its JV  Equity as was held by W-WCHP  immediately
     prior  to the Change of Control  and which was not subsequently transferred
     to W-L  or a  direct or  indirect wholly  owned Affiliate  of W-L)  to  the
     Non-Affected  Party, or as it  may direct, at a  price to be agreed between
     Glaxo and W-L or,  if they are  unable to agree upon  such price within  90
     calendar  days,  at  the Going  Concern  Value  of the  relevant  JV Equity
     determined in accordance  with Section  15.03 and taking  into account  the
     arrangements  contemplated by Section 12.03(b)  provided, however, that for
     the purposes  of  calculating  such Going  Concern  Value,  each  Operative
     Document  shall be  deemed to  continue for  a period  of 5  years from the
     acquisition pursuant to this clause (x); or
 
          (y) to require the  Affected Party to  purchase and accept  conveyance
     from  the Non-Affected Party  and its Affiliates  of the whole  of their JV
     Equity at a price to be agreed between Glaxo and W-L or, if they are unable
     to agree upon  such price  within 90 calendar  days, at  the Going  Concern
     Value of the relevant JV Equity determined in accordance with Section 15.03
     and  taking into account the  arrangements contemplated by Section 12.03(b)
     and Section 14.04.
 
For the purposes  of this Section  12.03(a), 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.
 
     (b)  In the event that the Non-Affected Party elects to exercise its option
under either clause (x) or clause (y) of Section 12.03(a) then:
 
          (i) subject to Section  14.04 hereof, the  Parties shall negotiate  in
     good  faith such  arrangements as may  be required to  ensure the continued
     operation of the JV Businesses;
 
          (ii) the Affected Party shall, as the case may be, be bound either (A)
     to, and to cause its Affiliates to, sell, transfer and convey the  Affected
     Party's,  and  such Affiliates',  JV Equity  (or if  the change  of control
     arises under  clause (ii)  or (iii)  of Section  12.03(a), such  of its  JV
     Equity as was held by W-WCHP immediately prior to the Change of Control and
     which  was  not subsequently  transferred to  W-L or  a direct  or indirect
     wholly owned Affiliate  of W-L)  to the Non-Affected  Party, or  as it  may
     direct,  pursuant  to  clause  (x)  above or  (B)  to  purchase  and accept
     conveyance from  the Non-Affected  Party  and its  Affiliates of  their  JV
     Equity pursuant to the terms of clause (y) above;
 
          (iii)  each  of the  Operative Documents  (other than  this Agreement)
     shall, to the extent  they relate to any  Ranitidine Product or OTC  Switch
     Product which is then being marketed by any JV Entity or is being developed
     therefor,  continue in full force and effect and shall be binding upon each
     of the Parties or their respective Affiliates, as the case may be,  subject
     only to the provisions of Section 14.04; and
 
          (iv)  this Agreement, and (save as provided in clause (iii) above) the
     other Operative Documents, and the Parties rights and obligations hereunder
     and thereunder  shall,  save  as  provided by  Sections  14.06  and  15.12,
     immediately be terminated.
 
     (c)  Without prejudice to the generality of Section 15.12 of this Agreement
but in accordance with the terms thereof, the Parties agree to keep confidential
the terms of this Section 12.03. Each  Party further agrees (i) not to give  any
indication  to any Third Party as to  whether any action, or what circumstances,
would give  rise  to a  Change  of Control,  (ii)  not to  inform,  directly  or
indirectly, any Third Party of what action such Party would or would not take in
the  event of a Change of Control, until such time as such Change of Control has
occurred and (iii) to inform the other Party immediately
 
                                       28
 

of any request by any Third Party  for information which it would be  prohibited
by this Section from divulging.

all material respects as of the relevant Closing Date, (ii) any breach by W-L or
any  of its Affiliates  of the terms of  this Agreement or  any of the Operative
Documents, or (iii)  Claims made by  a Third Party  which, if successful,  would
constitute a breach of a representation, warranty, covenant or agreement made by

pursuant to Section 11.07.
 
     (b) W-L agrees  to indemnify and  hold Glaxo  and each of  the JV  Entities
harmless  in respect of Claims made by or  owed to any Person to the extent such
Claims are  for bodily  injuries  or damages  suffered,  or for  obligations  or
liabilities  which arose, in connection  with products developed, marketed, sold
or distributed  by  W-L  or  any  of its  Affiliates  (other  than  products  so
developed, marketed, sold or distributed as part of the JV Businesses) except to
the  extent that  any JV Entity  is liable  to indemnify the  Parties in respect
thereof pursuant to Section 13.01.
 
     SECTION 13.03. Indemnification by Glaxo. (a) Glaxo agrees to indemnify  and
hold  W-L harmless  from all  Claims suffered  or paid  as a  result of  (i) the

liabilities which arose, in connection  with products developed, marketed,  sold
or  distributed  by Glaxo  or  any of  its  Affiliates (other  than  products so
developed, marketed, sold or distributed as part of the JV Businesses) except to
the extent that  any JV Entity  is liable  to indemnify the  Parties in  respect
thereof pursuant to Section 13.01.
 
     SECTION  13.04. Indemnification Generally. (a)  Any indemnification of W-L,
Glaxo, the  JV  Entities  or  their Affiliates  hereunder  or  under  any  other
Operative  Document, shall include and extend to the benefit of their respective
Affiliates and their respective directors and employees. Any Person that may  be
entitled  to indemnification under  this Agreement or  under any other Operative
Document (an 'Indemnified Party') shall give  notice to the Person obligated  to
indemnify  it (an 'Indemnifying Party') with reasonable promptness upon becoming
aware of the 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, upon agreeing irrevocably in a form and substance reasonably satisfactory
to the Indemnified Party to  be liable for all  Claims in respect thereof,  have
the  right  to undertake  the  defense of  any such  Claim  asserted by  a Third
 
                                       29
 

Party with counsel  satisfactory to  the Indemnified Party  and the  Indemnified
Party  shall  cooperate  in such  defense  and  make available  all  records and
materials 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 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.
 
     (b) Where any indemnity is claimed by a Party hereunder, or under any other
Operative  Document,  and  the  indemnity  is in  respect  of  any  claim, loss,
liability or obligation owed by one Party to the other, the Party claiming  such
indemnity  shall take all reasonable steps (the  cost of which shall be borne by
the Indemnifying Party) to mitigate such claim, loss, liability or obligation.
 
     (c) Any indemnification hereunder, or  under any other Operative  Document,
shall  be made on an after tax basis and net of any insurance proceeds recovered
by the relevant  Indemnified Party;  provided, however, that  if, following  the
payment  to an Indemnified Party of any amount under this Article XIII, or under
any other  Operative Document,  such Indemnified  Party recovers  any  insurance
proceeds  in respect  of the  Claim for  which such  indemnification payment was
made, the Indemnified Party shall promptly pay an amount equal to the amount  of
such  proceeds (but not exceeding the amount of such indemnification payment) to
the Indemnifying Party.
 
     SECTION  13.05.   Survival   of   Representations   and   Warranties.   The

the representations and warranties set forth in Sections 10.02(b), 10.04, 10.05,
10.06, 10.07 and 10.09, to the extent such representations and warranties relate

breach of representation or warranty after the  date which is one year from  the
date  of such commercial sale or termination or  two years from the date of this
Agreement, as the case may  be, if the Person seeking  to make such claim  shall
have  given written notice to the person against whom such claim is sought to be
made prior to such date specifying the breach complained of.

Entity:
 
          (i) all  Ranitidine  Rights  and  any NDA  filed  with  respect  to  a
     Ranitidine OTC Product shall revert to Glaxo; and
 
          (ii)  following the winding up of  the JV Entities pursuant to Section

     Operative Documents shall continue (subject to Section 14.04) in respect of
     all  such products  until such time  as the arrangements  or agreements are
     terminated pursuant to this  Agreement or until such  time as both  Parties
     agree  otherwise and this Agreement shall in all other respects immediately
     be terminated; and
 
          (ii) the Parties shall  negotiate in good  faith such arrangements  as
     may be required to ensure the continued operation of the JV Businesses with
     respect to such products.
 
     (d)  Should Glaxo or any Affiliate of Glaxo receive NDA Approval for an NDA
for Ranitidine OTC  prior to the  third anniversary of  the termination of  this
Agreement  (in whole  or in  part) pursuant  to this  Section 14.02  Glaxo shall
promptly notify W-L of receipt of the NDA Approval for Ranitidine OTC (the  'NDA
Notice')  and W-L  shall have  the option exercisable,  by notice  in writing to
Glaxo, at any time during the 90 calendar day period following W-L's receipt  of
the NDA Notice to reconstitute this Agreement and the JV Entities, as of, and on
the  terms existing as  of, the date of  termination, and in  the event of W-L's
exercise of such option, each of the Parties shall be deemed to be parties to  a
global  principles agreement identical to  this Agreement as of  the date of its
termination without  any further  action on  the  part of  any party  hereto  or
thereto.
 
     (e)  Without  prejudice  to  the  requirements  and  provisions  of Section
14.02(d), prior to the  third anniversary of the  termination of this  Agreement
(in  whole or in part) pursuant to  this Section 14.02 neither Party shall enter
into any arrangements which would be inconsistent with, or which would  obstruct
or  prevent, the  exercise of,  or the consummation  of W-L's  rights under, the
option set forth in Section 14.02(d).

     (in  the case of  a notice given  by W-L) or  W-L (in the  case of a notice
     given by Glaxo)  as the case  may be  (in this clause  (i) the  'Identified
     Party'),  or  of  a substantial  part  of  the property  or  assets  of the
     Identified Party,  under  Title  11  of the  United  States  Code,  as  now
     constituted  or hereafter  amended, or  any other  provision of  Federal or
     state  bankruptcy,  insolvency,   receivership  or  similar   law  in   any
     jurisdiction  (including  Part II  of the  United Kingdom's  Insolvency Act
     1986), (y) the appointment of a receiver, trustee, custodian, sequestrator,
     conservator or similar official of  the Identified Party, or a  substantial
     part  of its property or assets or (z) the winding-up or liquidation of the
     Identified  Party;  and  such   proceedings  or  petition  shall   continue
     undismissed for 60 days, or an order or decree approving or ordering any of
     the foregoing shall be entered;
 
          (ii)  if  a  Party  (in  this clause  (ii)  and  Section  14.03(b) the
     'Relevant Party') shall be in breach  or default in the performance of  any
     obligation under this Agreement or any of the Operative Agreements and such
     breach  is not remedied within six months  of receipt by the Relevant Party
     of written notice specifying, in  reasonable detail, the breach or  default
     complained  of, referring specifically to  this Section 14.03 and requiring
     that such  breach or  default be  remedied within  six months  of  receipt;
     provided, however, that such notice is given within 60 calendar days of the
     date  on which the Party  giving such notice first  knew, or should, in all
     the circumstances, reasonably
 
                                       31
 

     have known of the relevant breach;  and provided, further, that failure  to
     remedy such breach or default would have a materially adverse affect on the
     JV Businesses as a whole;
 
          (iii)  effective  on the  20th  anniversary of  the  Launch Date  of a
     Ranitidine  Product  by  the  U.S.  Partnership  or  any  subsequent  fifth
     anniversary  thereof;  provided,  however,  that  such  written  notice  of
     termination shall have  been provided not  less than 5  years and not  more
     than 6 years prior to the effective date of such termination; or
 
          (iv)  effective  on  the 25th  anniversary  of  the Launch  Date  of a
     Ranitidine  Product  by  the  U.S.  Partnership  or  any  subsequent  fifth
     anniversary  thereof  (the 'Effective  Date');  provided however  that such
     written notice of  termination shall  have been  provided not  less than  5
     years and not more than 6 years prior to the Effective Date.
 
     (b)  In the  event that  a Party  is entitled  to terminate  this Agreement
pursuant to Section 14.03(a)(ii)  and, at that time,  any Ranitidine Product  or
OTC Switch Product is then being marketed by any JV Entity or is being developed
therefore,  such Party (the 'Entitled Party') shall be entitled to elect, in the
written notice given pursuant to Section 14.03(a), that the JV Entities and  the
JV  Businesses in  respect of  such products  and this  Agreement and  the other
Operative Documents shall continue (subject to Section 14.04) only in respect of
such products  and  this  Agreement  and the  other  Operative  Documents  shall
otherwise immediately be terminated.
 
     (c)  In  connection with  the  making of  an  election pursuant  to Section
14.03(b), the Parties shall negotiate in good faith such arrangements as may  be
required to ensure the continued operation of the JV Businesses.
 
     (d) If notice is given pursuant to Section 14.03(a)(iii) and any Ranitidine
Product  or OTC  Switch Product is  then being marketed  by any JV  Entity or is
being developed therefor:
 
          (i) the JV  Entities and  the JV  Businesses, this  Agreement and  the
     other  Operative Documents shall  continue in respect  of all such products
     until such time as the  arrangements or agreements are terminated  pursuant
     to  this Agreement or until  such time as both  Parties may agree otherwise
     and this Agreement shall in  all other respects immediately be  terminated;
     and
 
          (ii)  the Parties shall  negotiate in good  faith such arrangements to
     ensure the continued operation  of the JV Businesses  with respect to  such
     products.
 
     (e)  if notice is given  pursuant to Section 14.03(a)(iv)  by Glaxo and any
Ranitidine Product or OTC Switch Product (the 'Existing Product') is then  being
marketed  by any JV Entity  or is being developed  therefor, Glaxo shall, on the
Effective Date, purchase and  accept conveyance from W-L  and its Affiliates  of
the  whole of  Glaxo's and  its Affiliates' JV  Equity at  a price  to be agreed
between the Parties or, if  they are unable to agree  upon such price within  90
calendar  days, at the Going  Concern Value of the relevant  JV Equity as of the
Effective Date determined in accordance  with Section 15.03, provided,  however,
that  for the purposes  of calculating such Going  Concern Value, each Operating
Document relating  to the  Existing  Product or  Products  and the  JV  Business
relating  thereto shall be deemed to continue for  a period of 15 years from the
Effective Date.
 
     (f) if notice  is given  pursuant to Section  14.03(a)(iv) by  W-L, all  JV
Entities,  JV Businesses and all Operative Documents shall immediately terminate
and W-L shall not be entitled to any compensation therefor.
 
     SECTION 14.04. Continued Arrangements. If any JV Entities or JV Businesses,
and the provisions  of any Operative  Documents, are to  continue in  accordance
with  Sections  12.03(b),  14.02(c)  or  14.03(b)  (a  'Continuation')  the then
existing Operative Documents relating to the Ranitidine Products and OTC  Switch
Products  then being marketed by any JV Entity or being developed therefor shall
continue as set forth in those Sections except as may otherwise be agreed by the
relevant Parties and except that:
 
          (a) in the case  of any Continuation pursuant  to Section 12.03(b)  or
     14.03(b),  each  existing  license  agreement,  services  agreement, supply
     agreement or other Operative  Document which is so  to continue shall  only
     continue,  for a period of 5 years  from the date of the Acquisition Notice
     or the notice given  pursuant to Section  14.03(a) provided, however,  that
     any such Operative Documents may be terminated by the Non-Affected Party or
     the  Entitled Party, as the  case may be, at  any time on reasonable notice
     (not to be less than 3 months); and
 
                                       32
 

          (b) in the case of any continuation pursuant to Section 14.02(c),  all
     Operative  Documents which are so to continue shall terminate 10 years from
     the date of the notice given pursuant to Section 14.02(c).
 
     SECTION 14.05.  Winding Up  and Liquidation.  During the  six-month  period
following  receipt  of a  notice of  termination pursuant  to Sections  14.02 or
14.03, and  pending  the distribution  and  payments required  by  the  relevant
Section  and  subject  to  any  continuing  business  under  Sections  12.03(b),
14.02(c), 14.03(b) and the other rights of the Parties under those Sections, the
JV Entities shall continue solely for  the purposes of winding up their  affairs
in  an orderly manner, liquidating such JV Entities and their respective assets,
and satisfying the claims of their creditors and no Party shall take any  action
that  is inconsistent with,  unnecessary to or  inappropriate for such purposes.
During the period of winding  up, the rights and  obligations set forth in  this
Agreement  with respect to the  management of the JV  Entities will continue and
the Governing  Board of  each JV  Entity shall  continue to  make all  decisions
relating  to  the  conduct of  any  business or  operations,  including, without
limitation, any decisions relating to the  sale or other disposition of that  JV
Entity's assets.
 
     SECTION  14.06. Survival of Rights. For the avoidance of doubt any exercise
by any of the  Parties of their  rights to terminate  this Agreement and/or  the
Operative  Documents  under Article  XII or  this Article  XIV shall  be without
prejudice to  any  other  rights  (including, without  limitation,  any  of  the
remedies  set forth  in Section 15.13)  the Parties  may have in  respect of any
breach or default by the other Party or any of its Affiliates of its obligations
hereunder or under the Operative Documents, or otherwise.

shall  bear its own  expenses, fees, costs  and disbursements, and  those of its
Affiliates, incurred  in  connection  with  this  Agreement  and  the  Operative
Documents  and  the consummation  of  the transactions  contemplated  hereby and
thereby and preparation therefor including:
 
          (a) in respect of W-L all  expenses, fees, costs and disbursements  of
     Bear  Stearns  &  Co.  Inc. arising  in  connection  with  the transactions
     contemplated by this Agreement; and
 
          (b) all Taxes incurred in connection with the assignment and  transfer
     of  assets to any JV Entity; provided, however, that, to the extent legally
     able to do so, each Party shall, and shall cause its Affiliates and the  JV
     Entities to, deliver to any other Party or any Affiliate of any Party or JV
     Entity  that is required by law to collect any Taxes exemption certificates
     in form and substance satisfactory to  such Party, Affiliate or JV  Entity,
     as the case may be, with respect to such Taxes.
 
     SECTION 15.02. Assignment and Binding Effect. Except as provided in Article
XII  or 14.03(e)  and any of  the rights  or obligations hereunder  shall not be
assignable by any Party without the prior written consent of the other  Parties.
This Agreement shall be binding upon and inure to the benefit of the Parties 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  compensation or value required by  Section
12.03(a)  or 14.03(e) within such period as  this Agreement may provide for such
agreement to be reached by  the Parties, each of W-L  and Glaxo shall choose  an
investment  banker to determine such compensation or value, which value shall be
the average of the two values determined by such investment bankers, unless such
values vary by more than  ten percent, in which  case the compensation or  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. Corporate Names. In the  event of the transfer by any  Party
(the  'Exited Party') of the whole of its and its Affiliates' JV Interest to any
Third Party or to the other Party or its Affiliates pursuant to Section 12.02 or
to the other Party or its Affiliates  pursuant to Article XIV, the successor  to
such  JV Interest and the other Party shall cease, and shall ensure that each of
their Affiliates and each of the JV Entities cease, to use any corporate name or
logo of the Exited Party, or any colorable imitation thereof, in connection with
the JV Businesses or otherwise.

     SECTION 15.05. Governing Law; Jurisdiction; Consent to Service of  Process;
Agent  for Service. (a) This Agreement shall be governed, construed and enforced
in accordance with the law of the State of New York without regard to principles
of conflicts of law.
 
     (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  such
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 purpose
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
sitting  in the Borough of Manhattan in the  City of New York. Each Party hereby
irrevocably waives, to the  fullest extent permitted by  law, the defense of  an
inconvenient  forum to the maintenance of such suit, action or proceeding in any
such court and further waives  the right to object,  with respect to such  suit,
action  or  proceeding, that  such court  does not  have jurisdiction  over such
Party.
 
     (d) Each Party  irrevocably consents  to service of  process on  it or  any
agent  for service  appointed from  time to  time (including  agents for service
appointed pursuant to clause (e) of  this Section 15.05) in the manner  provided
for  notices in Section 15.06. Nothing in  this Agreement shall affect the right
of either Party to serve process in any other manner permitted by law.
 
     (e) Glaxo  hereby designates  and appoints  Glaxo Americas  Inc., and  such
other  persons  (reasonably  satisfactory  to  W-L)  hereafter  selected  by it,
irrevocably agreeing in  writing so to  serve, as  its agent to  receive on  its
behalf  service of all process  in any proceedings referred  to in clause (b) of
this Section  15.04, such  service  being hereby  acknowledged  by Glaxo  to  be
effective and binding service in every respect.

          (x) to the extent necessary to comply with law or the valid order of a
