         West (directly and through its subsidiaries, including West/Nottingham)
is engaged in, among other things, the research and development of the
transmucosal delivery of pharmaceutical compounds using its patented and
proprietary drug-delivery technology. West, West/Nottingham and IDDS have
entered into a License Agreement, dated as of August 25, 2000 (the "License

under the License Agreement, all on the terms and subject to the conditions set
forth below.

                                    Agreement

         Accordingly, intending to be legally bound, the parties agree as
follows:

1.       Definitions. All capitalized terms used but not defined herein have the
         same meaning ascribed to them in the License Agreement. Terms defined
         parenthetically in this Agreement may be used in the singular or in the

2.       Grant of Option. Upon the terms and subject to the conditions set forth
         herein, West and West/Nottingham hereby grant to IDDS an exclusive
         option to include M-6-G as an Identified Compound under the License
         Agreement, and as such exercise the rights to the Chitosan-based

5.       Exercise of Option. IDDS may exercise the Option by written notice to
         West in the manner set forth in Section 9.3 hereof. West must receive
         such notice prior to expiration of the Option Period for IDDS to
         validly exercise the Option. Upon IDDS's exercise of the Option:

         5.1      IDDS shall pay to West a non-refundable license fee in the
                  amount of ***, payable upon execution of the License Addendum;

         5.2      West, West/Nottingham and IDDS shall execute the License
                  Addendum attached hereto as Exhibit A (the "License
                  Addendum"); and

         5.3      West, West/Nottingham and IDDS shall, within 45 days of the
                  exercise of the Option, enter into an Research and Development

         the Option during the Option Period, or if prior to the expiration of
         the Option Period, IDDS informs West that it will not exercise the
         Option, West will as from such moment be free to license the
         Chitosan-based Technology and Program IP in the Field of Use to third
         Persons for use with M-6-G, and IDDS will have no further rights under
         this Agreement or the License Agreement with respect to M-6-G.

                  Period.

                  may be terminated as follows:

                           party if the other party is adjudicated a bankrupt,
                           if insolvency, bankruptcy, reorganization, debt
                           adjustment or liquidation proceedings are instituted
                           against such party and not dismissed within 60 days
                           after the institution thereof, if a receiver or

9.       Miscellaneous Provisions.

         9.1      Assignment. Agreement may not be assigned or otherwise
                  transferred by any party without the consent of the other
                  parties; provided, however, that either party may, without
                  such consent, assign this Agreement and its rights and
                  obligations hereunder to its Affiliates or in connection with
                  the transfer or sale of all or substantially all of its
                  business, or in the event of its merger or consolidation or
                  change in control or similar transaction. Any purported
                  assignment in violation of the preceding sentence shall be
                  void. Any permitted assignee shall assume all obligations and
                  be entitled to all of the rights of its assignor under this
                  Agreement.

         9.2      Severability. In the event any one or more of the provisions
                  contained in this Agreement should be held invalid, illegal or
                  unenforceable in any respect, the validity, legality and
                  enforceability of the remaining provisions contained herein
                  shall not in any way be affected or impaired thereby, unless
                  the absence of the invalidated provision(s) adversely affect
                  the substantive rights of the parties. The parties shall in
                  such an instance use reasonable efforts to replace the
                  invalid, illegal or unenforceable provision(s) with valid,
                  legal and enforceable provision(s) which, insofar as
                  practical, implement the purposes of this Agreement.

         9.3      Notices. Any notice or other communication pursuant to this
                  Agreement will be deemed duly made or given: (i) when
                  delivered by hand; (ii) five business days after it is mailed,
                  certified or return receipt request, with postage prepaid;
                  (iii) when sent, if sent by telecopy (with receipt confirmed)
