WHEREAS,  Sponsor  desires  Diosynth to perform  services in accordance with the
terms of this Agreement and the Scope (as  hereinafter  defined)  related to the
production of the material  known as  Neutralase  (the  "Product")  and Diosynth
desires to perform such services.

WHEREAS,  Sponsor  and  Diosynth  executed a Letter  Agreement  on May 15,  2002
("Letter  Agreement") that provided for certain activities relating to the joint
development of the Scope, as defined below.

NOW,  THEREFORE,  in  consideration  of the above  statements and other good and
valuable  consideration,  the  sufficiency  and  receipt  of  which  are  hereby
acknowledged, the Parties hereto agree as follows:


Section 1.
Scope of Work
     a)   A  detailed  scope of work  document  ("Scope")  is  attached  to this
          Agreement   as  Appendix  1.   Diosynth   will  perform  the  services
          ("Program") for Sponsor in accordance with the Scope.

     b)   Sponsor  acknowledges  that  Diosynth  has  consulted  with Sponsor in
          designing the Program design in a manner  consistent with current U.S.
          and  E.U.  regulatory   guidelines.   Notwithstanding  the  foregoing,
          Diosynth does not warrant that the Program and/or the Program  results
          will satisfy the  requirements of any regulatory  agencies at the time
          of submission of Program results to such agencies.  Sponsor shall have
          responsibility  for  determining   regulatory  strategy  and  for  all
          regulatory  decisions  except for those matters that Diosynth,  in its
          sole discretion deem contrary to regulatory requirements.

     c)   Diosynth's   performance   of  the  Program  is  based  on   technical
          information  provided by or for the Sponsor  and  contingent  upon the
          accuracy of the  assumptions  and other  information  set forth in the
          Scope.  This information  will be translated into  development  and/or
          manufacturing    documents    (development   plans,   batch   records,
          specifications,   etc.).  cGMP  documentation  will  be  reviewed  and
          approved by the Sponsor as promptly as practicable.  Diosynth makes no
          warranties  that the  execution of the Scope  according to  Diosynth's
          procedures will result in any specific quantity or quality of Product.

                                       1


Section 2.
Program Performance
     a)   Diosynth shall use its best efforts to provide  facilities,  supplies,
          and staff necessary to complete the Program,  as it may be modified as
          provided  herein,  and in accordance with the terms of this Agreement.
          In the event of any conflict  between the Agreement and the Scope, the
          terms of this Agreement shall control.
     b)   Diosynth and  BioMarin  agree to comply with the  requirements  of the
          mutually  agreed upon  Quality  Agreement.  Failure to comply with the
          Quality  Agreement by either or both  Parties will be managed  through
          the provisions for dispute resolution  specified both in the Agreement
          and in the Quality Agreement.
     c)   Diosynth will appoint a program manager (the "Program  Manager") to be
          responsible for the management of the Program by Diosynth. The Program
          Manager   will   coordinate   performance   of  the  Program   with  a
          representative  designated by Sponsor (the "Sponsor  Representative"),
          which representative shall have responsibility relating to performance
          of the Program on behalf of Sponsor.  Unless  otherwise  agreed in the
          Scope, all  communications  between Diosynth and the Sponsor regarding
          the conduct of the Program pursuant to the Scope shall be addressed to
          or routed  through  the Program  Manager  and Sponsor  Representative,
          directly. Both parties may substitute their Program Manager or Sponsor
          Representative, as applicable, during the course of the Program.
     d)   Subject to the validity of the Program Assumptions,  as defined below,
          vial break for the first *****  fermentation shall occur no later than
          *****.  In the event such vial break is delayed  and fails to occur by
          such time and such delay is not  attributable  to an  invalid  Program
          Assumption or other act or omission of Sponsor,  Sponsor's  obligation
          to make the  payments  as set forth in  Section 6 related to the *****
          fermentations shall be correspondingly  delayed.  Such delayed payment
          obligation  shall be the sole and  exclusive  remedy for and impact of
          the delay described in this section 2(d).
     e)   Any commitment in the Letter Agreement to the payment of a reservation
          fee by Sponsor or  reservation  of capacity  by  Diosynth  relating to
          production  campaigns  in  excess of what is set forth in the Scope is
          hereby null and void and of no further force or effect.

Section 3.
Program Materials
     Sponsor will provide Diosynth with documentation and other such data, items
     or information  necessary to perform the Program as specified in the Scope,
     (the "Sponsor  Deliverables"),  and funding sufficient to obtain disposable
     lab supplies, disposable containers, product-contact materials or surfaces,
     filters,  resins,  test kits,  raw materials or other  process  consumables
     necessary to perform the Program  ("Process  Consumables"),  as well as all
     documentation  and such other data as may be necessary to apprise  Diosynth
     of the: stability of the Product,  cell line, reference standard,  shipping
     requirements or other Sponsor Deliverables, process characteristics, proper
     storage,  manufacturing and safety requirements.  Sponsor will also provide
     Diosynth with all necessary  information to effect the reliable transfer of
     the process from the Sponsor or a third party, as applicable, to Diosynth.

                                       2


Section 4.
Compliance with Government Regulations
     a)   Diosynth will perform the Program in  accordance  with the best of its
          understanding  the  then-current  state  of the  U.S.  Food  and  Drug
          Administration's  (FDA) current Good  Manufacturing  Practice,  21CFR,
          Sections  210-211  (cGMP) and ICH  Guidance  for  Industry,  QC7A Good
          Manufacturing Practices for Active Pharmaceutical Ingredients,  August
          2001 when  applicable.  Subject  to  paragraph  b) of this  Section 4,
          Diosynth will also comply in all material respects with all applicable
          U.S. and European government regulatory  requirements  concerning cGMP
          applicable to the Program.

     b)   Should  such  regulatory   requirements  change,   Diosynth  will  use
          reasonable efforts to satisfy the new requirements.  In the event that
          compliance with such new regulatory requirements necessitates a change
          in the  Scope,  Diosynth  will  submit to Sponsor a Change  Order,  as
          herein after defined, in accordance with Section 7 of this Agreement.

     c)   Subject to section  1(c),  in the event of a  conflict  in  government
          regulations,  Sponsor will designate,  in writing,  which  regulations
          shall be followed by Diosynth in its performance of the Program.


Section 5.
Facility Visits
     a)   Sponsor  reserves the right to have a person in Diosynth's  facilities
          during normal  business hours and with prior written notice to observe
          the manufacturing  process provided such visits are in accordance with
          the  "Guidelines  for  Sponsor  Visits"  attached  as  Appendix  3 and
          provided such access does not compromise  cGMP compliance or safety in
          the facility.  Diosynth will assist Sponsor in scheduling such visits,
          which will be in compliance  with  Diosynth's  requirement  to protect
          confidentiality of other clients.

     b)   Diosynth reserves the right to refuse visits,  audits or inspection by
          third  parties in the event that the third  party is a  competitor  of
          Diosynth   and/or  in  the  event  that   Diosynth's   obligations  of
          confidentiality  or business  may be  compromised  by such third party
          involvement.

                                       3


Section 6.

     b)   Sponsor  shall be  invoiced  and pay  *****.  Diosynth  shall  invoice
          Sponsor ***** in the amounts  indicated in the payment  schedule below
          and  Sponsor  shall  satisfy  such  invoices in  accordance  with this
          Section 6.

     c)   *****  Diosynth  shall invoice and Sponsor shall satisfy such invoices
          in accordance with this Section 6 on the dates indicated below.

     d)   Sponsor  has  paid an  initial  payment  of  *****  under  the  Letter
          Agreement.  This  amount  shall be  applied  to the  payment  due upon
          completion  the  ***** fermentation.

     e)   In addition to the  amounts set forth in the payment  schedule  below,
          Process  Consumables  purchased  for  the  Program  will  be  invoiced
          separately as such costs are incurred by Diosynth.  Sponsor  agrees to
          pay Diosynth's actual cost for the Process  Consumables  purchased for
          the Program *****.  Resins and ***** and additional  items agreed to
          by the Parties will not be subject to *****.

     f)   Diosynth shall purchase the following  item(s) in order to execute the
          Program ("Capital Equipment"):

                Mutually Agreed to Freezers for Released and Quarantined API

          Diosynth  shall rent the  following  item(s)  in order to execute  the
          Program ("Rented Equipment"):

                                    *****

          Diosynth  shall  invoice  Sponsor  and  Sponsor  shall pay all amounts
          reasonably   incurred  by  Diosynth   relating  to  the   procurement,
          installation and validation of these items at the time that such costs
          are incurred.  At the time the Rented Equipment is no longer necessary
          for  the  performance  of  the  Program,  Diosynth  shall  return  the
          equipment to its owner. At the time the Capital Equipment is no longer
          necessary for

                                       4



          the  performance of the Program,  Diosynth shall so notify Sponsor and
          allow Sponsor  reasonable  opportunity (not to exceed thirty (30) days
          from notice) to arrange, at Sponsor's sole expense, for the removal of
          the Capital Equipment from Diosynth's facilities.  If Sponsor makes no
          such arrangements within a reasonable time after notice,  title to the
          Capital   Equipment   shall  transfer  to  Diosynth   without  further
          consideration.

     g)   Payments are due thirty (30) days from the date of the  invoice.  Late
          payments are subject to an interest charge of one and one-half percent
          (1 1/2%) per month. Any payments that are greater than ninety (90)days
          past due constitute a material breach of this Agreement. Invoices will
          include a summary of activities  completed  during the invoice period,
          including;  labor  effort,  activities  completed and an indication of
          billable materials purchased.

     h)   Diosynth has allocated  resources to the Program that may be difficult
          or  impractical  to  reallocate  to other  programs  in the event of a
          delay.  In recognition of this,  Sponsor agrees to pay the amounts set
          forth in and in accordance with the payment schedule regardless of any
          delay in the Program related to invalid  Assumptions or decisions made
          during the course of the  Program to perform  process  development  or
          other  activities  not  expressly  provided for in the Scope.  In such
          event,  amounts  due under  the  payment  schedule  shall not apply to
          completion of any components of the Program that are delayed.  Sponsor
          and Diosynth shall negotiate a Change Order for  compensation  for the
          delayed and/or additional activities that may be necessary.

     i)   Diosynth  shall  invoice  Sponsor and Sponsor shall pay for any import
          duties  actually  incurred by Diosynth in executing  the Program *****
          during the term of Program as currently reflected in the Scope.

Section 7.
Change Orders
     a)   The  total  budget  for the  Program  specified  in  Appendix  2,  the
          individual budget components and the estimated  durations specified in
          the Scope are  subject to a number of  general  and  Program  specific
          assumptions as well as the accuracy,  timeliness and  completeness  of
          Sponsor's  Deliverables.  The assumptions relate to the Program design
          and objectives,  manpower  requirements,  timing,  capital expenditure
          requirements,  if any, and other matters relating to the completion of
          the  Program  as set forth in the Scope (the  "Program  Assumptions").
          Diosynth also assumes that the Sponsor will  cooperate and perform its
          obligations under the Agreement and Scope in a timely manner,  that no
          event outside the control of Diosynth will occur,  including,  without
          limitation,  the events  described in Section 18, (Force  Majeure) and
          that there are no changes to any applicable laws, rules or regulations
          which affect the Program (the foregoing  assumptions together with the
          Program Assumptions,  collectively,  the "Assumptions").  In the event
          that  any of  the  Assumptions  require  modification  or the  Program
          objectives  cannot be achieved based on the Assumptions  (each being a
          "Modification") then the Scope may be amended as provided in paragraph
          b) of this Section 7.

     b)   In the  event  a  Modification  is  identified  by the  Sponsor  or by
          Diosynth,  the identifying  Party shall notify the other Party as soon
          as is  reasonably  possible.  Diosynth  shall  provide  Sponsor with a
          change order  containing an estimate of the required  Modifications to
          the estimated  Program  budget and estimated  duration as specified in
          the Scope ("Change  Order") within ten (10) business days of receiving
          such notice.  Sponsor  shall use best efforts to respond in writing to
          such Change  Order within five (5)  business  days of  receiving  such
          Change  Order.  If Sponsor  does not approve such Change Order and has
          not  terminated  the  Program  but wants the Program to be modified to
          take into account the  Modification,  then Sponsor and Diosynth  shall
          use  best  efforts  to  agree  on a  Change  Order  that  is  mutually
          acceptable.  If  practicable,  Diosynth  shall  continue  work  on the
          Program during any such negotiations, but shall not commence work with
          respect  to the  Change  Order  unless  authorized  in  writing.  If a
          Modification  identified by Sponsor  results in a Change Order that is
          not agreeable to both parties  forty-five  (45) days after issuance of
          the  relevant  Change  Order and after good faith  negotiations,  this
          Agreement shall be deemed terminated by Sponsor pursuant to Section 21
          hereof.

                                       6


Section 8.
Confidential Information/Legal Proceedings
     a)   Diosynth will not disclose,  without Sponsor's written permission, any
          information  pertaining to the Program unless such disclosure:  (i) is
          to an affiliate of Diosynth that is under a similar obligation to keep
          such information  confidential;  (ii) is or becomes publicly available
          through no fault of  Diosynth;  (iii) is  disclosed  by a third  Party
          entitled to disclose it; (iv) is already known to Diosynth as shown by
          its prior  written  records;  or, (v) is  required  by any law,  rule,
          regulation, order decision, decree, subpoena or other legal process to
          be  disclosed.  If such  disclosure  is  requested  by legal  process,
          Diosynth will make all  reasonable  efforts to notify  Sponsor of this
          request  promptly  prior to any disclosure to permit Sponsor to oppose
          such  disclosure  by  appropriate  legal  action.  Diosynth  shall use
          reasonable   precautions  to  protect  the   confidentiality  of  such
          information  comparable  to  precautions  taken  to  protect  its  own
          proprietary information.

     b)   Sponsor will not disclose,  without Diosynth's written permission, any
          information pertaining to Diosynth's performance of the Program unless
          such  disclosure:  (i) is to an  affiliate  of Sponsor that is under a
          similar obligation to keep such information  confidential;  (ii) is or
          becomes  publicly  available  through  no fault of  Sponsor;  (iii) is
          disclosed  by a third Party  entitled to disclose  it; (iv) is already
          known to Sponsor  as shown by its prior  written  records;  or, (v) is
          required  by  any  law,  rule,  regulation,  order  decision,  decree,
          subpoena or other legal process to be disclosed. If such disclosure is
          requested by legal process,  Sponsor will make all reasonable  efforts
          to notify Diosynth of this request promptly prior to any disclosure to
          permit Diosynth to oppose such disclosure by appropriate legal action.
          Sponsor   shall   use   reasonable    precautions   to   protect   the
          confidentiality of such information comparable to precautions taken to
          protect its own proprietary information.

     c)   If Diosynth shall be obliged to provide testimony or records regarding
          any Sponsor Program in any legal or  administrative  proceeding,  then
          Sponsor shall  reimburse  Diosynth its  out-of-pocket  costs therefore
          plus an hourly fee for its employees or  representatives  equal to the
          internal  fully  burdened  costs  to  Diosynth  of  such  employee  or
          representative.

                                       7


Section 9.
Work Product
     a)   All work outputs  (e.g.  reports)  will be prepared  using  Diosynth's
          standard format(s) unless otherwise specified in the Scope.

     b)   Sponsor  will be supplied  with copies of reports and  completed  cGMP
          documentation  generated as a result of the Program.  All such written
          materials  will be archived by Diosynth for a period of five (5) years
          following  completion of the Program unless  otherwise  defined by the
          Program or required by applicable U.S. laws or regulations. Five years
          after  completion of the Program,  all of the  aforementioned  written
          materials  will  be sent  to the  Sponsor  and a  return  fee  will be
          charged.  The Sponsor may elect to have the materials  retained in the
          Diosynth  archives for an additional period of time at additional cost
          to Sponsor.  If the Sponsor  chooses to have  Diosynth  dispose of the
          written  materials,  a disposal  fee will be  charged.  Diosynth  will
          continue to retain such written  materials as required by  regulations
          and as may be required by law,  pertaining to such  activities as well
          as for archival purposes.

     c)   Diosynth  will  continue  to retain  Product  samples as  required  by
          regulations  and as may be  required  by law as well  as for  archival
          purposes.


Section 10.
Inventions and Patents
     a)   At Sponsor's  request,  Diosynth will assign to Sponsor any patentable
          Product  improvement   invention   discovered  by  Diosynth  employees
          exclusively as a result of performing the Program under this Agreement
          (a "Product Invention"); provided Sponsor requests such assignment, in
          writing,  within one year of notification  of such Product  Invention;
          provided, further that Diosynth shall retain all rights to any and all
          inventions  and  know-how   relating  to  manufacturing   methods  and
          processes   discovered  in   connection   with  the  Program  and  any
          pre-existing know-how ("Process Inventions").  If Sponsor requests and
          at Sponsor's expense,  Diosynth will execute any and all applications,
          assignments or other  instruments  and give  testimony  which shall be
          necessary  to apply for and  obtain  Letters of Patent of the US or of
          any foreign country with respect to the Product  Invention and Sponsor
          shall compensate  Diosynth for the time devoted to such activities and
          reimburse it for expenses incurred.

     b)   For Process Inventions, Diosynth will grant to Sponsor a royalty-free,
          perpetual,  world-wide,  non-exclusive  license  under terms  mutually
          agreed to by the  Parties  solely  for the field of use  required  for
          Sponsor to commercialize  the Product developed or produced under this
          Agreement.  If Diosynth  requests and at Diosynth's  expense,  Sponsor
          will  execute  any  and  all   applications,   assignments   or  other
          instruments  and give testimony  which shall be necessary to apply for
          and obtain Letters of Patent of the US or of any foreign  country with
          respect to the Process Invention and Diosynth shall compensate Sponsor
          for the time devoted to such  activities and reimburse it for expenses
          incurred.

                                       8


     c)   Diosynth  reserves  the  right to use data  during  the  course of the
          Program  to support  applications,  assignments  or other  instruments
          necessary to apply for and obtain Letters of Patent of the U.S. or any

between  Diosynth  and  Sponsor,  nor to  constitute  either party as the agent,

Section 14.
Default
     a)   If  Diosynth  is in default  of its  material  obligations  under this
          Agreement,  then Sponsor shall promptly  notify Diosynth in writing of
          any such default. Diosynth shall have a period of forty-five (45) days
          from the date of  receipt  of such  notice  within  which to cure such
          default;  provided that if such default  renders the Program  invalid,
          then Diosynth, shall, at its option, either: (i) repeat the Program at
          its cost within a time period  mutually  agreed to by it and  Sponsor;
          or, (ii) refund the contract price paid by Sponsor.  If Diosynth shall
          fail to cure such default within the specified cure period or commence
          the repetition of any portion(s) of the Program constituting the basis
          for the default,  as the case may be, then this  Agreement  shall,  at
          Sponsor's  option,   immediately  terminate.  In  the  event  of  such
          termination,  Sponsor's  sole  monetary  remedy  shall be, in the case
          where such default has not rendered the Program  invalid,  a reduction
          in the total  contract price for the Program in an amount equal to the
          difference between: (i) the total contract price for the Program; and,
          (ii) the value of the work properly performed,  and, in the case where
          such default does render the Program invalid, a refund of the contract
          price;  provided  however  that except as provided in  paragraph c) of
          this Section 14,  under no  circumstance  shall  Diosynth be liable to
          Sponsor in an amount that, in aggregate  exceeds,  the total  contract
          price paid for the  Program.  In the event of a  termination  due to a
          breach of this  Agreement by  Diosynth,  Diosynth  shall  deliver such
          documentation  and  records  relating  to the  Program as Sponsor  may
          reasonably request.

     b)   If  Sponsor  is in  default  of its  material  obligations  under this
          Agreement,  Diosynth shall  promptly  notify Sponsor in writing of any
          such default. Sponsor shall have a period of forty-five (45) days from
          the date of receipt of such notice  within which to cure such default;
          provided  that  if  Sponsor  fails  to cure  such  breach  within  the
          specified cure period,  this Agreement  shall,  at Diosynth's  option,
          immediately terminate.

     c)   Not   withstanding   anything   herein  to  the  contrary,   UNDER  NO
          CIRCUMSTANCES SHALL EITHER PARTY BE ENTITLED TO INCIDENTAL,  INDIRECT,
          CONSEQUENTIAL  OR  SPECIAL  DAMAGES  ARISING  IN  CONNECTION  WITH THE
          DEFAULT  OR BREACH OF ANY  OBLIGATION  OF THE OTHER  PARTY  UNDER THIS
          AGREEMENT,  THE SCOPE OR ANY DOCUMENTS OR APPENDICES  RELATED THERETO.
          EXCEPT FOR EACH PARTY'S  INDEMNIFICATION  OBLIGATIONS  FOR THIRD-PARTY
          CLAIMS SET FORTH IN  SECTION  16, OR ITS GROSS  NEGLIGENCE  OR WILLFUL
          MISCONDUCT,  EACH PARTY'S MAXIMUM  LIABILITY FOR DAMAGES IN CONNECTION
          WITH A CLAIM UNDER THIS AGREEMENT,  REGARDLESS OF THE CAUSE OF ACTION,
          WILL NOT EXCEED THE FEES PAID AND DUE HEREUNDER.

                                       10


     d)   EXCEPT AS EXPRESSLY STATED HEREIN, NEITHER PARTY PROVIDES TO THE OTHER
          PARTY HERETO ANY WARRANTIES,  EXPRESS OR IMPLIED,  WITH RESPECT TO THE
          MATERIALS AND SERVICES PROVIDED HEREUNDER,  AND ALL SUCH MATERIALS AND
          WARRANTIES,  EXPRESS OR  IMPLIED,  INCLUDING  WITHOUT  LIMITATION  ANY
          IMPLIED  WARRANTIES  OR  MERCHANTABILITY  OR FITNESS FOR A  PARTICULAR
          PURPOSE.

Section 15.
Dispute Resolution
     a)   In the event any dispute  shall arise between the Sponsor and Diosynth
          with respect to any of the terms and  conditions of this  Agreement or
          the Program;  then senior executives of the Sponsor and Diosynth shall
          meet as  promptly  as  practicable  after  notice of such  dispute  to
          resolve in good faith such dispute.

     b)   If the Sponsor and Diosynth are unable to  satisfactorily  resolve the
          dispute,   then  such  dispute  shall  be  referred  to  mediation  in
          accordance  with the American  Arbitration  Association.  If mediation
          fails to  resolve  the  dispute,  then such  dispute  shall be finally
          settled by an  arbitrator  in  accordance  with this  Section  15. The
          arbitration will be held in or around Wake County, North Carolina, and
          except as noted below, shall be conducted in accordance with the rules
          of the American Arbitration  Association by two arbitrators appointed,
          one by each Party.  If the arbitrators  appointed  cannot agree on the
          resolution of the dispute  within sixty (60) days after the dispute is
          submitted to them,  they shall thereupon  appoint a third  arbitrator,
          and if they fail to agree upon a third  arbitrator  within thirty (30)
          days  after a  deadlock  is  declared  by either  arbitrator,  a third
          arbitrator will be appointed by the American  Arbitration  Association
          upon the request of either  arbitrator.  The arbitrators shall have no
          authority to award consequential,  punitive or exemplary damages or to
          vary from or ignore the terms of this  Agreement and shall be bound by
          controlling law. Finally,  the Parties may seek judicial  intervention
          for emergency relief,  such as restraining  orders and injunctions and
          other equitable remedies where appropriate.

          Any  decision  by the third  arbitrator  and  either  one of the other
          arbitrators  shall be binding  upon the  Parties and may be entered as
          final  judgment  in any  court  having  jurisdiction.  The cost of any
          arbitration   proceeding   shall  be  borne  by  the  Parties  as  the
          arbitrators  shall determine if the Parties have not otherwise agreed.
          The  arbitrators  shall render their final  decision in writing to the
          Parties.

                                       11


Section 16.
Indemnification
     a)   Diosynth  shall  indemnify   Sponsor  and  its  affiliates  and  their
          respective  officers,  directors  and employees  from any loss,  cost,
          damage or expense (a "Loss") from any lawsuit,  action, claim, demand,
          assessment  or  proceeding  (a  "Claim")  for (i)  personal  injury to
          Program  participants or personal injury to any employee of Sponsor or
          property damage arising or occurring during the conduct of the Program
          as a result of Diosynth's negligence,  gross negligence or intentional
          misconduct  or inaction or (ii) the  negligence,  gross  negligence or
          intentional  misconduct or inaction of Diosynth in the  performance of
          its obligations  under this Agreement or Scope related to the Program;
          provided  that if such  Loss or Claim  arises in whole or in part from
          Sponsor's  negligence,  gross negligence or intentional  misconduct or
          inaction,  then the amount of the Loss that Diosynth  shall  indemnify
          Sponsor for  pursuant to this Section 16 shall be reduced by an amount
          in proportion to the percentage of Sponsor's responsibilities for such
          Loss  determined by a court of competent  jurisdiction  in a final and
          non-appealable  decision  or  in  a  binding  settlement  between  the
          Parties.

     b)   Sponsor  shall  indemnify   Diosynth  and  its  affiliates  and  their
          respective  officers,  directors,  employees and agents (the "Diosynth
          Group")  from any  Claim  or Loss  arising  from or  related  to:  (i)
          personal  injury to a participant in the Program or personal injury to
          any employee of the Diosynth  Group  directly or indirectly  caused by
          the Sponsor  Deliverables,  Process Consumables,  Materials,  Product,
          intermediates or the Program; (ii) Diosynth's proper performance of or
          involvement  with the raw material,  the Product or the Program or its
          obligations  under this Agreement or the Scope related thereto;  (iii)
          the  Agreement,  the  Program or any aspect  thereof  set forth in the
          Scope or the Program violates any applicable law, rule,  regulation or
          ordinance;  (iv) the  harmful or  otherwise  unsafe  effect of the raw
          materials or Product,  including,  without  limitation,  a Claim based
          upon  Sponsor  or  any  other   person's   use,   consumption,   sale,
          distribution  or  marketing  of  any  substance,   including  the  raw
          material,   Materials  or  the  Product;  (v)  the  negligence,  gross
          negligence  or  intentional  misconduct  or inaction of Sponsor in the
          performance of its  obligations  under this Agreement or Scope related
          to the Program;  (vi) the infringement or alleged  infringement of the
          Scope or the  Program  or the  Product  on the  intellectual  property
          rights  of  a  third  party;   or,  (vii)  the  Sponsor's   violation,
          non-compliance  or  non-performance  of  any  of  the  terms  of  this
          Agreement;  provided  that if such Loss or Claim (other than a Loss or
          Claim described in clause (iv) hereof) arises in whole or in part from
          Diosynth's  negligence,  gross negligence or intentional misconduct or
          inaction,  then the amount of such Loss that Sponsor  shall  indemnify
          the Diosynth Group for pursuant to this Section 16 shall be reduced by
          an   amount   in   proportion   to  the   percentage   of   Diosynth's
          responsibilities  for such Loss as  determined by a court of competent
          jurisdiction  in a final and  non-appealable  decision or in a binding
          settlement  between  the  Parties.  Sponsor  shall not  indemnify  the
          Diosynth  Group from any Loss from any claim  described in clause (iv)
          hereof  arising  solely  from the  willful  misconduct  or inaction of
          Diosynth.

                                       12


     c)   Upon  receipt of notice of any Claim which may give rise to a right of
          indemnity   from  the  other   Party   hereto,   the   Party   seeking
          indemnification  (the  "Indemnified  Party") shall give written notice
          thereof to the other Party,  (the  "Indemnifying  Party") with a Claim
          for indemnity  ("Indemnity  Claim").  Such Claim for  indemnity  shall
          indicate  the  nature of the Claim and the basis  therefore.  Promptly
          after a claim is made for which the Indemnified Party seeks indemnity,
          the  Indemnified  Party shall permit the  Indemnifying  Party,  at its
          option and  expense,  to assume the  complete  defense of such  Claim,
          provided  that  (i) the  Indemnified  Party  will  have  the  right to
          participate  in the  defense  of any  such  Claim  at its own cost and
          expense,  (ii) the Indemnifying  Party will conduct the defense of any
          such Claim with due regard for the business  interests  and  potential
          related   liabilities   of  the   Indemnified   Party  and  (iii)  the
          Indemnifying Party will, prior to making any settlement,  consult with
          the  Indemnified  Party  as to  the  terms  of  such  settlement.  The
          Indemnified  Party shall have the right,  at its election,  to release
          and  hold  harmless  the  Indemnifying   Party  from  its  obligations
          hereunder  with respect to such Claim and assume the complete  defense
          of the same in return  for  payment by the  Indemnifying  Party to the
          Indemnified Party of the amount of the Indemnifying Party's settlement
          offer. The Indemnifying  Party will not, in defense of any such Claim,
          except with the consent of the Indemnified Party, consent to the entry
          of any judgment or enter into any settlement which does not include an
          unconditional term thereof, the giving by the claimant or plaintiff to
          the  Indemnified  Party of a release  from all  liability  in  respect
          thereof.  After notice to the  Indemnified  Party of the  Indemnifying
          Party's election to assume the defense of such Claim, the Indemnifying
          Party shall be liable to the Indemnified Party for such legal or other
          expenses  subsequently incurred by the Indemnified Party in connection
          with the defense thereof at the request of the Indemnifying  Party. As
          to those Claims with respect to which the Indemnifying  Party does not
          elect to assume  control of the defense,  the  Indemnified  Party will
          afford the  Indemnifying  Party an  opportunity to participate in such
          defense at the Indemnifying Party's own cost and expense, and will not
          settle or otherwise  dispose of any of the same without the consent of
          the Indemnifying Party.

Section 17.
Representation and Warranty/Limitation of Warranty
Sponsor  hereby  represents  and  warrants to  Diosynth  that it has legal title
and/or a valid  license  to the cell line,  raw  material,  expression  systems,
process patents and the Product and that  Diosynth's  performance of the Program
will  not  violate  or  infringe  on  the   patents,   trademarks,   tradenames,
servicemarks or copyrights of any other party.


Section 18.
Force Majeure

such Party's  reasonable  control,  including,  but not limited to, acts of God,
fire,  explosion,  weather,  disease,  war,  insurrection,  civil strife, riots,
government  action,  or power failure,  provided that such performance  shall be
excused only to the extent of and during such disability. Any time specified for
completion of  performance  in the Scope falling due during or subsequent to the
occurrence of any or such events shall be automatically extended for a period of
time to recover from such disability.  Diosynth will promptly notify Sponsor if,
by reason of any of the events  referred  to herein,  Diosynth is unable to meet
any such time for performance specified in the Scope. If any part of the Program
is invalid as a result of such  disability,  Diosynth will, upon written request
from Sponsor,  but at Sponsor's  sole cost and expense,  repeat that part of the
Program affected by the disability.

Allocation of Resources
If delays in the agreed commencement or performance of the Program occur because
of the Sponsor's  request or inability to supply  Diosynth  with agreed  Sponsor
Deliverables or any information  required to begin or perform the Program within
thirty (30) days of such agreed time,  Diosynth may reallocate  resources  being
held for performance of the Program without incurring liability to Sponsor. Such
reallocation of shall not be the exclusive impact of a Sponsor delay.


Section 20.

          control that causes the Program to be ceased or significantly delayed,
          Diosynth shall use commercially  reasonable  efforts to reduce cost to
          Sponsor  associated  with  the  termination,  and  Sponsor  shall  pay
          Diosynth upon receipt of Diosynth's  invoice all of its costs incurred
          or  irrevocably  obligated,  plus, as liquidated  damages and not as a
          penalty,  a cancellation  fee in immediately  available funds equal to

          then-current   Change  Orders  and  amendments   associated  with  the
          Agreement,  reduced by those amounts  described in the second sentence
          of this paragraph a).

     b)   The  termination  of this  Agreement  for any reason shall not relieve
          either Party of its obligation to the other for obligations in respect
          of: (i) confidentiality of information;  (ii) consents for advertising
          purposes and publications; (iii) indemnification;  (iv) inventions and

Section 27.
Entire Agreement;  Modification/Counterparts
     a)   This  instrument  including  the  attached  Appendices  sets forth the
          entire  Agreement  between  the  Parties  hereto  with  respect to the
          performance  of the  Program  by  Diosynth  for  Sponsor  and as such,
          supersedes  all prior and  contemporaneous  negotiations,  agreements,
          representations,  understandings, and commitments with respect thereto
          and shall take precedence over all terms, conditions and provisions on
          any  purchase  order  form or form of  order  acknowledgment  or other
          document purporting to address the same subject matter. This Agreement
          shall not be waived, released,  discharged, changed or modified in any
          manner except by an instrument signed by the duly authorized  officers
          of each of the Parties hereto,  which  instrument  shall make specific

     b)   This Agreement becomes effective and binding on both Parties on and as
          of the last date that the Parties hereto have executed this Agreement.

1.0  EXECUTIVE SUMMARY

1.1      Scope Overview

BioMarin  Pharmaceutical,  Inc.  (Sponsor) has contracted with Diosynth RTP Inc.
(Diosynth)  to perform  tasks  related to process  transfer,  scale-up  and cGMP
manufacturing of NeutralaseTM (Product). Sponsor has completed Phase II clinical
trials and initiated  Phase III trials with  Neutralase  manufactured by a third
party.  Key to the  objectives  and  assumptions  made  in  this  Scope  are the
significant  process  modifications being made and/or evaluated by Sponsor *****
prior to Diosynth's  performance  of this Scope as well as the  requirement  for
scale-up of the process by Diosynth following these modifications.  In addition,
Sponsor has clearly stated its desire to assume  responsibility  for all process
development  activities  and outcomes and wishes to contract  with Diosynth only
for  execution  of process  scale-up  and  subsequent  manufacturing  runs*****,
Diosynth is responsible only for the execution of the defined activities and not
for the results thereof.

NeutralaseTM  is an  injectable  Heparinase  I  intended  for  use in  reversing
anti-coagulation  induced by  heparin  and other  heparin-like  anti-coagulants.
*****  This  Scope  assumes  that  the  recombinant  line  will be used  for the
manufacture of bulk Product. *****

The short lead time requested by Sponsor for Product delivery in addition to the
availability of capacity in the manufacturing schedule at Diosynth have resulted
in Diosynth's  development of a dual site manufacturing  strategy  (described in
detail below) that is designed to be in manufacture for Product within Sponsor's
desired timeframe. This dual site strategy provides for fermentation and initial
recovery at Diosynth  RTP's site with  completion  of  downstream  processing at
Diosynth  B.V.'s Oss Site. By  transferring  the  downstream  process to the Oss
facility  for the  current  campaign,  the  cost of  technology  transfer  for a
subsequent scale up for future commercial supply can be reduced for the Sponsor.

1.2      Manufacturing Strategy

Sponsor will  transfer  the  existing  *****  Product  manufacturing  process to
Diosynth.  Diosynth  will  scale-up and run the process  ***** and  subsequently
scale-up to ***** under process  direction  from Sponsor.  Diosynth will perform
fermentation,  recovery and partial purification  processes at its manufacturing
site in North Carolina (RTP). The product of these activities will be shipped to
the Diosynth  facility in Oss, the  Netherlands,  for  completion  of downstream
processing  and bulk fill.  Limited in process and  limited lot release  testing
will be  performed  at the  respective  sites  of  manufacture  to  assess  cGMP
compliance, with Sponsor performing the final testing and lot release.

Diosynth's strategy for process transfer, scale up and manufacturing includes:

o    Review of the existing process development and manufacturing documentation.

o    Perform two fermentation runs ***** followed by two purification runs
     intended to demonstrate the Sponsor's process at an intermediate scale to
     support stepwise scale-up of the process.

o    Draft technology transfer and engineering documentation, obtain and release
     raw materials and develop control programs for bioreactor operation,
     according to Sponsor's direction.

o    Perform two manufacturing runs ***** according to cGMP.

1.3      Timeline

The activities  listed in this Scope are  anticipated to take ***** to complete.
Appendix 1 provides a Gantt chart for the timeline of anticipated activities and
duration based on the Program Assumptions listed in section 5.0.

                                 APPENDIX THREE
                            (Sponsor Visit Guidelines)

[OBJECT OMITTED]
                          Guidelines for Sponsor Visits

1.  Access to production areas:

During  production  runs,  it may be possible to arrange  Sponsor  access to the
manufacturing  floor,  if space allows.  A Diosynth  escort will be assigned and
will accompany the Sponsor at all times while in controlled  areas of the plant.
During this time it is critical that the visitor:
     o Follows all GMP / access / gowning / safety procedures as directed by
       Diosynth personnel.
     o Does not touch or operate any equipment in the production area.
     o Does not direct manufacturing personnel. Suggestions or recommendations
       may be made to an area Manager or Director.
     o Does not remove any documentation or in-process data. Requests for
       documentation must be made in writing to an area Manager or Director. Any
       documentation provided in this fashion will be tracked by the area
       Director.
     o Makes all requests for additional immediate in-process sampling, in
       writing to the area Manager or Director with full justification, prior to
       sampling.
     o Does not enter areas where production is ongoing for another client.
     o Does not take any photos inside any Diosynth facility. Diosynth can
       provide digital photographs as appropriate.

Lack of adherence to these very basic  guidelines  will result in immediate loss
of access to production areas.

2.  Audits:

Existing customers:
o    Diosynth will support one (1) audit of up to two (2) days duration, during
     each twelve (12) month period of an active contract, to be billed on a time
     and materials basis or as specified in the contract.

o    The audit may be performed by the Sponsor or by an external third party,
     with third party costs being at the sole expense of the client. A maximum
     of three (3) auditors / Sponsor participants will be allowed to take part
     in the actual audit, due to space limitations and dedicated Diosynth
     personnel availability.

o    Dates for the audit must be arranged and agreed with Diosynth a minimum of
     one month prior to the audit. Diosynth reserves the right to make final
     approval of audit dates, based on availability of the facility and
     appropriate Diosynth personnel.

                                       36


o    Confidentiality agreements must be in place with all parties participating
     in the audit, prior to scheduling the audit.

o    Three weeks before the audit occurs, a list of areas / topics to be covered
     in the audit will need to be received by Diosynth. This will allow Diosynth
     to ensure appropriate Diosynth personnel availability during the audit,
     while also ensuring minimal impact to programs in production for other
     clients.

o    No access will be allowed into areas where production is underway for
     another client.

o    Any audit observations being sent to Diosynth for review or response must
     be provided by the client, not directly from a third party auditor.
     Diosynth will formally respond to audit findings within forty-five (45)
     days.

o    All audit observations are confidential, covered in the confidentiality
     agreement between Diosynth and the client, and may not be shared with any
     other party without express written permission. All third party auditors
     must also sign confidentiality agreements with Diosynth confirming
     adherence to this condition and may not share their findings beyond the
     Sponsor who contracts the audit, without express written permission from
     Diosynth.

o    It may be possible to arrange additional audits during a given year, to be
     billed to the Sponsor on a time-and-materials basis. An estimate of this
     charge can be provided in advance and will be determined by the scope of
     the audit and the resources required to support it.
