      after interest begins to accrue until full payment of all amounts due
      MCGILL is made.

      shall specifically include the following, as applicable:

                (A)     NET SALES amounts.

      10.2      ATTORNEYS' FEES

                        In the event any suit or other proceeding is reasonably
      necessary and is commenced to construe, enforce, or terminate any
      provision of this LICENSE AGREEMENT, the nonprevailing party shall pay the
      prevailing party, in addition to all other amounts to which the prevailing
      may be entitled, a reasonable sum for attorneys' fees and costs incurred

      10.3      ENTIRE AGREEMENT

                        This LICENSE AGREEMENT constitutes the entire agreement
      and understanding between MCGILL and NOVOPHARM with respect to the

      with the laws of the Province of Ontario.

      10.5      FORCE MAJEURE

                        Neither MCGILL not NOVOPHARM shall be in default of the
      terms of this LICENSE AGREEMENT because the party delays performance or
      fails to perform such terms; provided such delay or failure is not the
      result of the party's intentional or negligent acts or omissions, but the
      result of causes beyond the reasonable control of such party. Causes

      respectively, who shall meet and make a good faith effort to resolve the
      matter. In the event the parties fail to resolve such dispute by
      negotiations the matter shall be submitted first to mediation by a
      mediator chosen jointly by the parties involved. If after ninety (90)
      days the dispute has not been resolved by mediation, the dispute shall

                10.7.2  The party desiring such arbitration shall give written
      notice to that effect and shall in such notice appoint as one of the
      arbitrators a disinterested person of recognized competence in the medical
      field, who shall have experience in arbitrating disputes arising under
      agreements dealing with subject matters similar to the subject matter
      hereof. Within fifteen (15) business days thereafter, the other party
      shall, by written notice to the originating party, appoint as one of the
      arbitrators a second disinterested person having the foregoing
      qualifications. Unless the parties have agreed upon and appointed a third
      arbitrator within ten (10) business days of the appointment of the second
      arbitrator, the two arbitrators appointed by NOVOPHARM and MCGILL shall
      select a third disinterested person having the foregoing qualifications
      within twenty (20) business days of the appointment of the second
      arbitrator. If the two arbitrators fail to agree upon the selection of
      such third arbitrator within such twenty (20) business day period, either
      NOVOPHARM or MCGILL upon written notice to the other may apply to the
      Ontario Court (General Division) for the appointment of a third
      arbitrator. If the second arbitrator shall not have been appointed as
      aforesaid, the first arbitrator shall proceed to determine the matter in
      dispute. The arbitrators thus appointed shall use all reasonable efforts
      to determine the matter in dispute as soon as practicable and in any event
      within thirty (30) business days of the appointment of the third
      arbitrator.

                10.7.3  Each party shall be entitled to present evidence and
      argument to the arbitrators. The arbitrators shall have the right only to
      interpret and apply (and not change) the provisions of this LICENSE
      AGREEMENT and may not deprive NOVOPHARM or MCGILL of any right or remedy
      provided by this LICENSE AGREEMENT or at law.

                10.7.4  The determination of the majority of the arbitrators
      shall be conclusive and binding upon the parties and judgment upon the
      same may be entered in any court having jurisdiction. The arbitrators
      shall give written notice to the parties stating their determination and
      shall furnish to each party a signed copy of such determination.

                10.7.5  In the event of failure, refusal or inability of any
      arbitrator to act, a new arbitrator shall be appointed in his stead, which
      appointment shall be made in the same manner as provided above for the
      appointment of the arbitrator so failing, refusing or unable to act.

                10.7.6  The expenses of any arbitration hereunder shall be borne
      as awarded by the arbitrators, or, in the absence of such an award, shall

      authorized representative of the party making the waiver. No such waiver

This will confirm the agreement between NOVOPHARM LTD. of Scarborough, Ontario
M1P 2Y1 ("NOVOPHARM") and McGill University ("MCGILL") whereby NOVOPHARM is
prepared to support studies conducted at MCGILL on "An exploration of the

Payments shall be received in two bi-annual instalments commencing with the
starting date of the Project. The execution of the research may also be
supported by funds from other research organizations and the University. The
investigator shall have freedom within the allotted amount to rebudget within
the categories outlined in Appendix B in order to utilize funds in the best
interest of the study.

REPORTING

NOVOPHARM shall receive a comprehensive report on the activities and results of

CONFIDENTIAL MATERIAL

In the course of the research project, MCGILL and NOVOPHARM may share
confidential materials and data with each other. Such materials shall be kept
confidential for a period of five years and shall not be disclosed to anyone
without a "need to know" within NOVOPHARM or MCGILL. Each party shall also
strictly protect such information from disclosure to third parties. The

NOVOPHARM may terminate this Agreement and will be obligated to pay MCGILL only
for costs and expenses which have already been incurred or which cannot be
reasonably avoided.

             AN EXPLORATION OF THE REGULATION OF POLYAMINE TRANSPORT
                                IN HUMAN DISEASE

     Polyamines are now known to be critical in the growth and differentiation
of many normal and malignant tissues. In particular, various neurologic
disorders and malignancies have been associated with disruption of the
regulation of polyamine levels through biosynthesis and transport. Whereas some
of the genes important in the biosynthesis and regulation of polyamine Ievels
have been characterized, no polyamine transport gene has yet been characterized
in mammals. In some of our recent work, we believe that we have identified a
potential probe for a human polyamine transport protein. The expression of mRNA
homologous with this probe has been shown to be distributed among human tissues
similarly to known levels of polyamine and polyamine metabolism; furthermore,
exposure of various types of cells to either mitogens or poisons of polyamine
metabolism resulted in the anticipated up- or down-regulation of the expression
of the gene homologous to the putative human polyamine transport probe.

     In order to verify the identity of the gene homologous to this probe as a
regulator of polyamine transport, we will identify the yeast gene and its
location (preliminary data suggests that the yeast gene can be readily
identified and cloned; the yeast gene is undoubtedly nearly identical to the
human gene and will make it possible to quickly obtain the exact human gene(s).)
In addition, we are proceeding to "knock-out" the yeast gene in order to
unequivocally prove the function as a transport protein for polyamines. In the
first year, we would hope to complete the yeast work and begin, if not conclude,
the cloning of the putative human polyamine transport protein. During the rest
of the first and in the second year, we would expect to use the probe on various
cell lines and tissues (in Northern blot and FISH, fluorescence in situ
hybridization, assays) to demonstrate the role played by this putative polyamine
transport in nonmalignant neurologic disorders like Alzheimer's Disease as well
as malignancies of the brain, colon, prostate, skin, etc.

The isolation and demonstration of the identity of this human polyamine
transport protein would provide diagnostic and research tools. In addition, the
characterization of the gene and its regulatory control would be crucial to the
design of chemotherapeutic agents to modify disease conditions. Finally, the
isolation of the gene would provide an opportunity to consider the use of gene
therapy to selectively knockout or up-regulate polyamine levels as may be needed
to normalize tissue and organ function.
