                  shall be shared equally between BOP and BTP.

                  proceedings on patent and patent applications on PB in all
                  other countries within the Territory (which specifically
                  excludes the United States of America and Canada).

3.       Co-Development Plan

                  the USA and Canada will be in the name of BTP. BOP will be
                  responsible for conducting all clinical trials and the filing
                  and prosecution of all applications with applicable regulatory

         3.2      The parties will promptly share all information generated
                  under this co-development program pursuant to confidentiality
                  including, without limitation, all information with respect to

                  preparations of PB or any product incorporating the PB
                  Technology.

         3.3      BTP shall pay all costs and expenses of any work deemed
                  necessary for the development of PB in the USA and Canada. BOP
                  shall pay all costs and expenses of any work deemed necessary

                  and BOP to disclose to one another certain confidential
                  information. In the event of receipt of such confidential

                  validity and effect of the other provisions of this Sublicense
                  Agreement shall not be affected thereby.

         5.4      Waiver: The waiver by either party or the failure by either
                  party to claim a breach of any provision of this Sublicense
                  Agreement shall not be deemed to constitute a waiver or
                  estoppel with respect to any subsequent breach or with respect
                  to any provision thereof.

         5.5      Successors and Assigns: This Sublicense Agreement shall be
                  binding upon and shall inure to the benefit of the Parties and

                  conveyance of the Sublicensed Technology.

         5.7      Counterparts: This Sublicense Agreement may be executed in any
                  number of counterparts, each of which shall be deemed an
                  original but all of which together shall constitute a single
