                 quantity  permitted  under  clauses 4.1 and 4.3,
                 AZ  shall   endeavour   to  supply   the  excess
                 quantity  within  the same time  frame but shall
                 not be liable for its failure to do so.

         Quality Assurance  Agreement for each Manufacturing Site
         shall be  substantially  in the form set out at Schedule
         6.  Any  amendments  to such  form  shall  be as  agreed
         between the  Parties in writing  with the  intention  of
         ensuring   quality  of  products  in   accordance   with
         applicable  laws and  regulations.  Neither  Party shall
         unreasonably   withhold  its  consent  to  an  amendment
         requested by the other Party.



                                      227




7.2      In addition to its product recall  obligation  under the
         Quality  Assurance  Agreements,  the  Purchaser  shall,
         after the  Transfer  Date,  if  appropriate  and at AZ's
         request  and expense  carry out any recall  which may be
         required by AZ in respect of AZLAD Products  released by
         AZ prior to the Effective Date.

7.3      AZ shall maintain and manage its  manufacturing  plants,
         facilities  and  operations  and  the  Purchaser   shall
         maintain  and manage its  warehousing  and  distribution
         facilities in compliance  with all  applicable  laws and
         regulations  and in such manner as not to jeopardise the
         validity of the Marketing  Authorisations and continuous
         supply of AZLAD  Products under this  Agreement.  During
         the time that AZ is  manufacturing  AZLAD  Products  for
         the Purchaser  under this Agreement the Purchaser  shall
         have access on  reasonable  notice to the  Manufacturing
         Sites for the purpose of assessing  the  production  and
         quality of the AZLAD Products.

7.4      The  provisions  of clause  7.3 shall not  preclude  AZ,
         from   sub-contracting   the   whole   or  part  of  the
         manufacture  or storage of AZLAD  Products  but AZ shall
         be  responsible  for  ensuring  that the  changes do not
         prejudice the validity of the  Marketing  Authorisations
         and  continuous  supply  of AZLAD  Products  under  this
         Agreement  and AZ shall  give to the  Purchaser  as much
         prior  notice  of such  changes  as it shall  reasonably
         require for  regulatory  purposes.  AZ shall provide the
         Purchaser with the manufacturing,  technical and quality
         assurance  data  required to prepare  and  support  such
         submissions  and AZ  shall  co-operate,  at its cost and
         expense,  as necessary to support such  submissions.  In
         the  event  of AZ  sub-contracting  the  manufacture  or
         storage of AZLAD  Products,  it shall be responsible for
         ensuring the due compliance by its  sub-contractor  with
         the terms of this Agreement.

8.       DEFECTS

8.1      Any  delivery  shortage,  visible  damage  or  defect in
         AZLAD  Products shall be reported by the Purchaser to AZ
         within 30 days of  opening  of the  transport  container
         which shall mean the  shrink-wrapped  pallet  container.
         All  complaints,  other than defects which are incapable
         of  being  discovered  upon  opening  of  the  transport
         container,  shall be waived unless reported to AZ within
         such period of 30 days.



                                      228




8.2      In the  event  that the  defect  is  found to have  been
         caused  by  AZ  breaching  its  obligations   under  the
         Quality  Assurance  Agreement,  AZ shall replace free of
         charge such  quantity of AZLAD  Products as are affected
         by the defect  together  with  reimbursing  or crediting
         the  Purchaser  for either (at AZ's  option) the cost of
         destruction  or the return of the affected  Product.  No
         AZLAD  Product may be returned to AZ without  AZ's prior
         written permission.

8.3      If the Parties are unable to agree on the  allocation of
         responsibility  for a defect in an AZLAD  Product,  then
         the  Parties  shall  refer the  matter to a  specialised
         pharmaceutical   laboratory  of   international   repute
         acceptable  to  both  Parties  (the  "Laboratory").  The
         Laboratory  shall be deemed to act as an expert  and not
         as an  arbitrator  and any  decision  by the  Laboratory
         shall (in the  absence of  objection  on the  grounds of
         manifest  error  within  30  days  of the  issue  of its
         decision)  be  conclusive  and  binding on the  Parties.
         The fees and expenses of the  Laboratory  shall be borne
         equally by the Parties.

8.4      In the event that  AZLAD  Products  need to be  replaced
         due  to  a  defect,  regardless  of  the  allocation  of
         responsibility,  AZ shall use its reasonable  endeavours
         to  manufacture   replacement  AZLAD  Products  for  the
         Purchaser as quickly as possible.

         received  or  obtained  by  either  Party  under  or  in
         connection  with  this  Agreement  shall be  treated  as
         confidential  by both Parties and shall not be disclosed
         by  either  Party to any  third  party or used by either

                                      229



         (iii)   as  required  by  law,  or  any   regulatory  or
                 governmental authority.

9.2      In  the  event  of  a  Party   disclosing   confidential
         information  to a third party in accordance  with clause
         9.1(i) or (ii),  it shall  ensure that the  recipient is
         aware of the  confidential  nature  of such  information
         and,  in the case of  information  relating  solely  to
         dental   products,   shall   be   bound  by  the  same
         restrictions  on use and  disclosure as the  disclosing
         Party.

9.3      The  following  information  is not subject to the above
         confidentiality obligations or restrictions on use:

         (i)    information  which,  at the time of  acquisition,

                 otherwise,  except by breach  of  obligation  of
                 the receiving Party;

         (iii)   information   which  the  receiving   Party  can
                 establish   by   competent   proof  was  in  its
                 possession  at the time of  acquisition  and not
                 subject  to any  restriction  on  disclosure  or
                 use;

         (iv)    information   independently   developed  by  the
                 receiving  Party  without  the benefit or use of
                 confidential information; and

         (v)     information   received   from   third   parties,
                 provided that such  information was not obtained
                 by such third  party,  indirectly  or  directly,
                 from  the  other  Party  under   obligation   of
                 confidence.

9.4      The obligations and restrictions  imposed by this clause
         shall  continue  in force for the  duration  of 10 years
         from the Effective Date.

         (iii)   that   other   Party    makes   any    voluntary
                 arrangement   with  its   creditors  or  becomes

11.      INDEMNIFICATION

11.1     The Purchaser  shall  indemnify and hold harmless AZ and
         each of its officers,  employees and agents (each an "AZ
         Indemnitee")  against  any  and  all  losses,   damages,
         liabilities  or expenses in connection  with any actions
         or  demands   that  may  be  brought   against   any  AZ
         Indemnitee by any  non-Affiliate  of the Parties arising
         out  of  the  manufacture,  use or  sale  of  any  AZLAD
         Product by the  Purchaser,  or by AZ in accordance  with
         this Agreement,  the Existing  Contracts,  or clause 9.1
         of  the  AZLAD   Products   Agreement,   including   any
         investigation  by any  governmental  agency with respect
         to the quality of such Product,  or any claim for death,
         personal  injury or property damage asserted by any user
         of such Product,  provided that the Purchaser  shall not
         be  obliged  to  indemnify  any AZ  Indemnitee  from any
         loss,  damage,  liability or expense in connection  with
         any  action  or  demand  arising  out  of any  event  or
         circumstance  in which AZ is  obliged to  indemnify  the
         Purchaser pursuant to clause 11.2.

11.2


                                      232



AZ  shall  indemnify  the  Purchaser  and  each of its  officers,
         employees  and agents  (each a  "Purchaser  Indemnitee")
         against any losses, damages,  liabilities or expenses in
         connection  with  any  actions  or  demands  that may be
         brought   against  any   Purchaser   Indemnitee  by  any
         non-Affiliate  of the  Parties to the extent  such event
         or circumstance:  (i) occurred before the Effective Date
         or (ii) arises out of the  manufacture of AZLAD Products
         by AZ  otherwise  than in  accordance  with  GMP and the
         relevant  Marketing  Authorisation or the sale of AZLAD
         Products by AZ otherwise  than in  accordance  with the
         relevant Marketing Authorisation.

11.3     As  promptly  as   practicable   after  any   indemnitee
         referred to in clauses  11.1 or 11.2  obtains  knowledge
         of any  action  or  demand as to which it will or may be
         entitled to indemnity  under such clause,  it shall give
         notice to the  Parties,  provided  that the  failure  to
         give such notice  shall not  preclude or bar such claims
         but shall  reduce such claims to the extent of prejudice
         to  the  indemnifying   Party.  The  indemnifying  Party
         shall be  entitled  to  participate  in any  proceedings
         relating to such action or demand.  The indemnitee shall
         obtain the prior  approval  of the  indemnifying  Party,
         which  approval  shall  not  be  unreasonably  withheld,
         before  entering  into any  settlement  or compromise of
         such  action  or  demand,  if as a  result  thereof  the
         indemnifying Party's indemnity  obligations with respect
         to such action or demand will not be discharged.

12.      MISCELLANEOUS PROVISIONS

12.1     Neither  Party  shall be liable on any  account  for any
         failure  to fulfil any terms of this  Agreement  if such
         fulfilment   has  been   frustrated  by  Force  Majeure,
         provided   that  the  Party  which  is  prevented   from
         performing  exercises  diligent  efforts  to resume  its
         performance hereunder as soon as practicable.

12.2     Subject to clauses  2.5,  7.4 and 12.13,  neither  Party
         shall be  entitled to assign or  sub-license  any of its

         written  consent of the other Party,  which shall not be
         unreasonably withheld.

12.3     If either Party shall assign or  sub-license  any of its
         rights or obligations  under this Agreement  (other than
         under the Contract Manufacturing Agreements):



                                      233




         (i)     it  shall  give  notice  of such  assignment  or
                 sub-licence  to the other  Party in writing  not
                 later  than  seven  days  after the date of such
                 assignment or sub-licence,

         (ii)    if so required by the other  Party,  it shall be
                 a condition of such  assignment  or  sub-licence
                 that the  assignee or  sub-licensee  shall enter
                 into a direct  undertaking  with the other Party
                 to   exercise   any   right  and   perform   any

12.5     The   Parties   agree  that  this   Agreement   and  the
         transactions  contemplated  hereby  shall be governed by
         and  interpreted in accordance  with the laws of England
         unless  otherwise  stated herein or in any  supplemental
         agreement.

12.6     This  Agreement and any amendments  hereto  comprise all
         the terms and  conditions of the  agreement  between the
         Parties in respect of the subject  matter  hereof.  This

         writing duly signed by both Parties.



                                      235




12.7     In the event of any conflict  between the  provisions of
         this  Agreement  and  any  supplemental  agreement,  the
         provisions  of this  Agreement  shall prevail and in the
         event of any  conflict  between  the  provisions  of the
         clauses  of this  Agreement  and the  provisions  of any
         Schedule, the provisions of the clauses shall prevail.

12.8     If the Parties  shall  execute  any  document in English
         and another language,  or if the Parties shall agree the
         text of any  document  in  English  and the  text of the
         executed   Agreement   shall  be   written   in  another
         language,  the English text shall prevail as between the
         Parties  in the  event of there  being  any  discrepancy
         between the texts and either  Party shall at the request
         of  the  other  Party  join  with  it  in   executing  a
         supplemental  agreement  to amend  the  foreign  text to
         remove such discrepancy.

12.9     If  any  provision  of  this  Agreement  is  held  to be
         invalid   or   unenforceable   by  a   competent   legal
         authority,  the Parties shall meet and mutually agree to
         amend this  Agreement  to  incorporate  new terms  which
         shall,  to the  greatest  extent  possible,  restore the
         economic   balance   contemplated   by  the  Parties  in
         entering into this Agreement.

12.10    The  failure by either  Party to exercise or enforce any
         right  conferred  upon it hereunder  shall not be deemed
         to be a  waiver  of such  right  or  operate  to bar the
         exercise or enforcement thereof at any time thereafter.

12.11    Completion of the performance of any obligation  arising
         under this  Agreement  shall not  affect the  continuing
         validity of any provision of this Agreement.

12.12    It is the  intention of the Parties that this  Agreement
         shall be  binding  on their  respective  Affiliates  and
         accordingly  each  of them  undertakes  to  procure  the
         compliance  with the  provisions  of this  Agreement  of
         their respective Affiliates as if signatories hereto.



                                      236




12.13    Either  Party  hereto may  transfer any of its rights or
         obligations   hereunder   to  any  of  its   Affiliates,
         provided that each Party (i) guarantees the  performance
         of such Party's  obligations so transferred  pursuant to
         this clause,  (ii) such  transfer  shall not relieve the
         transferring   Party  of  its  obligations   under  this
         Agreement and (iii) prior to such  Affiliate  ceasing to
         be an Affiliate  the  transferring  Party shall  procure
         that all  rights  and  obligations  so  transferred  are
         transferred back to the transferring Party.

12.14    Both Parties hereto agree to execute  promptly and shall
         compel their  respective  Affiliates to execute promptly
         any   separate    agreements    or   other    documents,
         undertakings,  or consents  necessary or  appropriate to
         carry  out  the  provisions  of  this  Agreement.   Such
         agreements,  documents,  undertakings and consents shall
         neither  expand nor contract the rights and  obligations
         of the Parties hereto.

12.15    Except as otherwise  provided  for herein,  all disputes
         arising in  connection  with this  Agreement,  including
         any  amendments,  shall be  finally  settled  under  the
         Rules   of   Conciliation   and   Arbitration   of   the
         International  Chamber of Commerce by three  arbitrators
         appointed in  accordance  with such Rules.  The arbitral
         proceedings  shall be held in  English  and  shall  take
         place in London.  The arbitral  tribunal  shall  conduct
         and complete its  proceedings and render a final written
         opinion  within  180  days  of the  date  on  which  the
         arbitral  proceedings  are initiated.  The Parties agree
         that any right of appeal  against any arbitral  award or
         order  to  the  Court  is  hereby  waived.  The  Parties
         further  agree that it is their  expressed  intent  that
         until the tribunal  renders its final award,  the status
         quo of the continuing  relationship  is to be maintained
         to the maximum  possible extent and that the arbitrators
         are hereby  directed to enforce  such  agreement  of the
         Parties.  In  addition,   the  Parties  agree  that  any
         injunctive  relief  must  be  sought  in  such  arbitral
         proceeding  and  not  in  any  other  proceedings.   The
         Parties  further agree that any award or order issued by
         the   arbitral   tribunal   shall  be   enforceable   in
         accordance  with  its  terms in any  court of  competent
         jurisdiction.

12.16    Each Party shall be entitled to make such  announcements
         relating  to  this   Agreement   and  any   supplemental
         agreements  as shall  be  appropriate,  but  each  Party
         shall  first  consult in good faith with the other Party
         concerning the contents of such announcements.
