       the names of the INVENTORS are mentioned in all publications and patent
       applications based on their work.

       methods of using same, that are developed independently by the COMPANY.
       However, the COMPANY agrees to grant to the UNIVERSITY and NDDO a royalty
       free, paid


                                                                     Page 5 of 8

       compositions, COMPOUND analogues and methods of using same jointly
       developed by the COMPANY and the UNIVERSITY and/or the NDDO. The COMPANY

       publication, by means of a written notification to NDDO, UNIVERSITY
       and/or INVENTOR, (with a maximum of one year after the date notification)
       until all confidential information is deleted from the manuscript and /
       or until a patent application, as specified in Article 16, covering the
       subject matter disclosed in the submission is filed.

18.    This Agreement is entered into in good faith and nothing in the foregoing
       implies or is intended to imply that UNIVERSITY or INVENTOR or NDDO or
       NCE warrant that COMPOUNDS have or will have ultimate therapeutic utility
       in humans or animals. If on the other hand the marketable product derived
       from the COMPOUNDS to be sold by COMPANY may cause any damage to humans

       against any liability arising therefrom.

       PATENTS by paying the fees due in respect thereof. For that purpose, NDDO
       will forward the fee notes concerned to the COMPANY. Copies of such fee
       notes shall be returned to NDDO by COMPANY, mentioning SETTLED ON [DATE].
       Consequently, the risk of lapse of rights into the PATENTS shall be born
       by COMPANY subject to COMPANY having received adequate and timely
       pre-notification. UNIVERSITY/NDDO/NCE/INVENTOR shall grant authority to
       COMPANY to pursue infringement of the PATENTS, on the basis of which
       authority to COMPANY shall vigorously pursue infringements of the
       PATENTS. UNIVERSITY/NDDO/NCE/INVENTOR shall grant COMPANY the authority
       to file new patent applications with respect to the marketable products
       derived from the COMPOUNDS. UNIVERSITY/NDDO/NCE/INVENTOR shall provide
       COMPANY with all necessary co-operation with respect to such patent
       applications, submitted to the restrictions set out in Article 16.

       liability for claims by third parties for infringements of patents owned
       by third parties and/or, for Product liability

22.    COMPANY has the right to sublicense the COMPOUNDS in all MARKETS. The
       COMPANY retains the responsibility to ensure that sub-licensee fulfils
       the obligations of this Agreement. Except as provided for herein, COMPANY
       shall not assign any of its rights or obligations under the terms of this
       Agreement, nor shall it grant any sub-licenses with respect to the


                                                                     Page 6 of 8


       COMPOUNDS without prior written approval of UNIVERSITY/NDDO/NCE/INVENTOR,
       such written approval will not be unreasonable withheld. NDDO agrees to
       respond to such requests within 30 days. However, should such assignment
       of rights or obligations of this Agreement, and/or sub-license thereof,
       be coincident to the sale of the COMPANY, or should said assignment of
       rights or obligations of this Agreement, and/or sub-license thereof be to
       a wholly owned subsidiary of the COMPANY, written approval of
       UNIVERSITY/NDDO/NCE/INVENTOR shall not be required.

23.    Term and Termination

       23.1   Unless otherwise terminated under provisions of Article 23.2, this
              Agreement and the license granted under Article 7 shall continue

              PATENT covered by this license. However, COMPANY's obligations
              under this section and section 12 of this LICENSE AGREEMENT will
              cease no later than the earliest of: 1) five (5) years after the
              last PATENT expires, or 2) the sale of any generic form of the

       23.2   The COMPANY may terminate this Agreement, at their option and
              without prejudice to any of its other legal and equitable rights
              and remedies, by giving the UNIVERSITY/NDDO/NCE/INVENTOR notice
              in writing at least three (3) months in advance of the effective
              date of such termination.

       23.3   Should the COMPANY terminate this Agreement without cause, the
              provisions of Articles 6, 9, 12, and 17 shall remain in force
              until all obligations under the aforementioned Articles have been
              fulfilled.

       23.4   Upon termination of this Agreement, each party will within thirty
              (30) days return to the other all tangible Confidential
              Information and Property of the other party (except one copy which
              may be retained by legal counsel solely for evidentiary purposes
              in the event of a dispute), and each party will deliver to the
              other a copy of any documentation in its possession or control
              specifically relating to the Joint Inventions.

24.    COMPANY, NDDO, NCE, UNIVERSITY and INVENTOR shall be excused from
       performance under this Agreement for any period and to the extent that it
       is prevented from performing any Services pursuant to this Agreement, in
       whole or in part, as a result of any event of force majeure, including an
       act of God, war, civil disturbance, court order, labour disputes, or
       other cause beyond its reasonable control, and such non-conformance shall
       not be a default hereunder or a ground for termination of this Agreement
       as otherwise provided herein.


                                                                     Page 7 of 8
