ARTICLE 2. ORDERS AND DELIVERY

2.1   Within fifteen (15) days from the beginning of each calendar quarter, PDC
      shall furnish to Diosynth a rolling forecast of its requirements of the
      Product, together with the delivery dates, during the next four (4)
      calendar quarters whereby the required quantities for the first quarter
      shall be a firm purchase order for the supply of the Product and shall not
      deviate more than twenty (20) percent from the preceding forecast provided
      to Diosynth.

2.2   Diosynth will deliver the Product to PDC within the date stipulated in the
      firm purchase order. Diosynth will use its best commercial efforts to
      deliver as soon as possible any quantities in excess of the purchase order
      as determined in Article 2.1.

2.3   Delivery of each batch of Product shall be effectuated FOB PDC's
      manufacturing facility (INCOTERMS 2000).

2.4   Each shipment of the Product shall be accompanied by relevant certificates
      of analysis and an invoice.

ARTICLE 3. PRODUCT QUALITY

3.1   Diosynth warrants that the Product delivered under this Agreement to PDC
      shall conform to the specifications set forth In Appendix A and shall be
      manufactured according to applicable regulations of Good Manufacturing
      Practices.

3.2   Within at most thirty (30) days of delivery of batches of the Product, PDC
      shall inform Diosynth of any nonconformity of the delivered batches with
      the specifications as set forth in Appendix A hereto. If Diosynth agrees
      with PDC's opinion, PDC shall dispose of the defective delivery as
      Dlosynth shall direct and at Diosynth's expense and Diosynth shall replace
      such delivery free of charge as soon as practical thereafter. If PDC falls
      to notify Diosynth of its faulty manufacture within thirty (30) days from
      the date of delivery of any quantity of Product, this delivery shall be
      deemed to conform to the specifications for the purpose of this Article 4.

      If the parties fail to agree on whether a delivery is defective or on the
      responsibility therefor, the matter shall be finally determined by an
      independent expert to be nominated by agreement between the parties. The
      expert's opinion shall be binding upon the parties and his fees and
      expenses shall be borne by the party against which the expert's opinion is
      given. If the expert's opinion is not wholly in favor of one party, the
      parties shall share the costs equally.

ARTICLE 4. USE

      PDC shall use the Product only in compliance with regulatory approvals
      and, in the absence of regulatory approvals, only in connection with
      research and the development of the insulin formulation.

ARTICLE 5. REGULATORY ISSUES

5.1   Diosynth agrees to file, at no costs to PDC and not later then December
      31, 2001, a US Drug Master File and any similar filing required in Canada
      and the European Union covering the manufacture of the Product.

5.2   Diosynth will cooperate with PDC and, without limitation, further support
      PDC with all other possible and reasonable regulatory information during
      the term of this agreement.

ARTICLE 6. INDEMNIFICATION

6.1   PDC shall indemnify and hold Diosynth harmless against all claims made
      and/or suits brought against Diosynth by third parties in respect of any
      personal loss, damage or injury arising or resulting result from the use
      of the Product or the formulation developed and sold by PDC, except in
      case that any such personal loss, damage or injury arises or results from
      the faulty manufacture by Diosynth.

6.2   Diosynth shall indemnify and hold PDC harmless against all claims made
      and/or suits brought against PDC by third parties in respect of any
      personal loss, damage or injury arising or resulting or alleged to
      directly arise or result from the appropriate use of the Product in so far
      as in any particular case such personal loss, damage or injury is
      attributable to faulty manufacture by Diosynth.

6.3   In no event shall either party be liable for any consequential damages,
      costs, and losses whatsoever endured by the other.

ARTICLE 7. PRICE AND PAYMENT

7.1   For the quantities to be supplied by Diosynth in 2000, PDC shall pay the
      purchase price of [...***...], whereas for supply of the quantities in
      2001 and 2002 the purchase price will be [...***...].

7.2   Diosynth is willing to accept a purchase price of [...***...] as the
      commercial market price in the year 2000. In this respect "commercial
      market price" is considered to be the price for quantities as described in
      Article 1.3. This commercial market price in the year 2000 will be used as
      a basis for the determination of the commercial market price in subsequent
      years. To that end, on or before September 30 of each calendar year,
      parties will in good faith determine the commercial market price for the
      product for the following calendar year. In any case the purchase price
      will not increase, on a year by year basis, with more than the increase of
      the labor cost index in the Netherlands, as published by the C.B.S.
      (Centraal Bureau voor de Statistiek"). In addition, the price to PDC will
      not be higher than to any other customer as long as the quality and the
      quantity of the Product to that other customer is substantially comparable
      with the quantity and quality of the Product supplied to PDC.

7.3   Payment of the Product delivered shall be made by PDC within thirty (30)
      days of the date of invoice or receipt of the Product, whichever shall
      last occur.

ARTICLE 8. INFORMATION, SECRECY AND NON-USE

8.1   Upon signature of this Agreement and during the term thereof, Diosynth
      shall provide PDC with all information and documentation about the Product
      necessary for the development of the insulin formulation.

8.2   Each party shall keep strictly confidential and not use, except for the
      purpose and during the course of this Agreement, nor disclose, except to
      governmental authorities for registration purposes, any information which
      it receives from the other and which is marked confidential. Each party
      shall impose such confidentiality obligation on its employees.

8.3   This confidentiality obligation does not apply to any part of the
      confidential information which

      -     at present is publicly known or thereafter becomes publicly known
            through no fault of the receiving party,
      -     is already known by the receiving party on the date of disclosure,
            provided such prior knowledge can be adequately substantiated by
            documentation;
      -     properly and lawfully becomes available to the receiving party from
            a third party.

8.4   For the purpose of the development of the formulation PDC shall be
      entitled to disclose information to third parties provided that these
      third parties shall be bound by substantially the same secrecy obligations
      as contained herein.

ARTICLE 9. TERM AND TERMINATION

9.1   This Agreement shall become effective as of January 1st, 2000 and shall
      continue to be in force until terminated as provided herein.

9.2   Notwithstanding the preceding paragraph, this Agreement may be terminated
      forthwith by registered or certified mail:

      a)    By both parties for any reason or no reason with a two year written
            notice; or
      b)    by either party in the event the other party shall substantially
            breach any of its obligations under this Agreement and shall fail to
            remedy such breach within sixty (60) days from receipt of written
            notice or such breach by the party not in default; or
      c)    by either party in the event of the other party's liquidation,
            bankruptcy or state of insolvency; or
      d)    by PDC, with 30 days written notice if a controlling regulatory
            authority either fails to approve or withdraws approval of the
            insulin formulation. In the event that the product is withdrawn by
            regulatory decree in a portion, but not all of the market, then PDC
            shall have the right to reduce the minimum quantities with 30 days
            written notice.

9.3   In the event Diosynth terminates this Agreement pursuant to article 9.2a)
      and Diosynth is PDC's sole source of supply for the Product, Diosynth
      shall have the responsibility to qualify an alternative source of supply,
      based on Diosynth's manufacturing process, which should enable PDC to
      continue its commercial activities with respect to the Product without
      interruption or disadvantage.

ARTICLE 10. FORCE MAJEURE

Neither party shall be responsible for failure or delay in performance of any of
its obligations under the Agreement due to force majeure such as war,
insurrection, strikes, lockouts, acts of God, governmental action, or any other
contingency beyond its reasonable control.

ARTICLE 11. HARDSHIP

Should it appear that at any time during the lifetime of this Agreement and for
any reason, the terms of this Agreement are not workable from an economical
point of view, the parties to this Agreement at the request of the party
concerned shall meet within two (2) months from the date of that request and
expend their best efforts to re-establish the terms of this Agreement in a
mutually satisfactory way.

ARTICLE 12. MISCELLANEOUS

12.1  This Agreement shall be governed by and construed in accordance with the
      laws of England applicable to agreements executed and to be performed
      therein.

12.2  All disputes arising in connection with the present Agreement, which
      cannot be settled amicably, shall be finally settled by the competent
      court of London, England. The prevailing party shall be entitled to
      recover its legal fees and expenses.

12.3  No amendment and/or modification of this Agreement shall be valid unless
      it is laid down in writing and signed by both parties.
