                           termination; and upon termination of this AGREEMENT,
                           any and all sublicenses granted by LICENSEE and
                           approved by BOARD shall be assigned to BOARD; or

                           thirty (30) days after execution, modification, or
                           termination; and upon termination of this AGREEMENT,

                           outside of LICENSED TERRITORY as long as there are no
                           competing products outside of LICENSED TERRITORY
                           (with minimum annual royalties of [*], and [*] of all
                           consideration other than Research and Development
                           ("R&D") money received by LICENSEE from any
                           sublicensee pursuant to Paragraphs 3.3 and 3.4 herein
                           above, including but not limited to royalties,
                           up-front payments, marketing, distribution,
                           franchise, option, license, or documentation fees,
                           bonus and milestone payments and equity securities,
                           payable within thirty (30) days after March 31, June
                           30, September 30, and December 31, at which time
                           LICENSEE shall also deliver to BOARD and MDA a true
                           and accurate report, giving such particulars of the
                           business conducted by LICENSEE and its sublicensee,
                           if any exist, during the preceding three (3) calendar
                           months under this AGREEMENT as are pertinent to an
                           account for payments hereunder. Such report shall
                           include at least (a) the quantities of LICENSED
                           PRODUCTS that it has produced; (b) the total SALES,
                           (c) the calculation of royalties thereon; and (d) the
                           total royalties so computed and due BOARD. In the
                           event that there are competing products outside of
                           LICENSED TERRITORY, then no royalty will be due
                           related to that specific territory. Simultaneously
                           with the delivery of each such report, LICENSEE shall
                           pay to BOARD the amount, if any, due for the period
                           of such report. The requirement to pay minimum annual
                           royalties shall commence upon FDA final approval of
                           the LICENSED PRODUCTS. A pro rata portion of the
                           annual minimum royalties shall be payable in respect
                           of any partial period not constituting a full year.
                           Should LICENSEE be obligated to pay running royalties
                           to third parties to avoid infringing such third
                           parties' patent rights which dominate BOARD'S PATENT
                           RIGHTS, LICENSEE may reduce the running royalty due
                           MDA by such running royalties to such third parties,



[*]     Confidential treatment requested pursuant to a request for confidential
        treatment filed with the Securities and Exchange Commission.  Omitted 
        portions have been filed separately with the Commission.

                           provided, however, the running royalty due MDA shall
                           in no case be less than one-half the rates stated
                           herein above.

         4.2      During the Term of this AGREEMENT and for one (1) year
                  thereafter, LICENSEE shall keep complete and accurate records
                  of its and its sublicensees' SALES and NET SALES of LICENSED
                  PRODUCTS to enable the royalties payable hereunder to be
                  determined. LICENSEE shall permit BOARD or its
                  representatives, at BOARD'S expense, to periodically examine
                  after reasonable written notice to LICENSEE its books,

                  purpose of and to the extent necessary to verify any report

                  amount equal to or greater than five percent (5%) of the total

                  MATTER in the LICENSED TERRITORY and LICENSEE'S
                  commercialization plans for the upcoming year. Such report
                  will be deemed for all purposes to be confidential information
                  governed by Article XI hereof.

         4.4      All amounts payable hereunder by LICENSEE shall be payable in

         6.1      LICENSEE shall have the obligation of enforcing at its expense

                  such enforcement. LICENSEE shall pay MDA a royalty on any
                  monetary recovery, net of LICENSEE'S direct out-of-pocket
                  expenses from such enforcement not otherwise paid to third
                  parties, to the extent that such monetary recovery by LICENSEE
                  is held to be damages or a reasonable royalty in lieu thereof.
                  In the event that LICENSEE does not file suit against a
                  substantial infringer of such patents within six (6) months of
                  knowledge thereof, then BOARD shall have the right to enforce
                  any patent licensed hereunder on behalf of itself and LICENSEE
                  (MDA retaining all recoveries from such enforcement) and/or
                  reduce the license granted hereunder to non-exclusive.

         6.2      In any suit or dispute involving a third party infringer, the
                  parties shall cooperate fully, and upon the request and at the
                  expense of the party bringing suit, the other party shall make
                  available to the party bringing suit at reasonable times and
                  under appropriate conditions all relevant personnel, records,
                  papers, information, samples, specimens, and the like which
                  are in its possession.


                               VII. PATENT MARKING

         7.1      LICENSEE agrees that all packaging containing individual
                  LICENSED PRODUCT(S), and documentation therefor, sold by
                  LICENSEE, AFFILIATE, and sublicensees of LICENSEE will be
                  marked permanently and legibly with the number of the
                  applicable patent(s) licensed hereunder in accordance with
                  each country's patent laws, including Title 35, United States
                  Code.


                              VIII. INDEMNIFICATION

         8.1      LICENSEE shall hold harmless and indemnify BOARD, SYSTEM, MDA,
                  its Regents, officers, employees, students, and agents from
                  and against any claims, demand, or causes of action
                  whatsoever, costs of suit and reasonable attorney's fees
                  including without limitation those costs arising on account of
                  any injury or death of persons or damage to property caused
                  by, or arising out of, or resulting from, the exercise or
                  practice of the license granted hereunder by LICENSEE or its
                  officers, employees, agents or representatives.

                  for the purposes of this AGREEMENT, and not disclosed by the
                  recipient party (except as required by law or court order),

         10.2     Each party's obligation of confidence hereunder shall be
                  fulfilled by using at least the same degree of care with the

                         XIII. WARRANTY: SUPERIOR-RIGHTS

         13.1     Except for the rights, if any, of the Government of the United
                  States as set forth herein below, BOARD represents and
                  warrants its belief that it is the owner of the entire right,
                  title, and interest in and to LICENSED SUBJECT MATTER, and
                  that it has the sole right to grant licenses thereunder, and
                  that it has not knowingly granted licenses thereunder to any
                  other entity that would restrict rights granted hereunder
                  except as stated herein.

         13.2     LICENSEE understands that the LICENSED SUBJECT MATTER may have
                  been developed under a funding agreement with the Government
                  of the United States of America and, if so, that the
                  Government may have certain rights relative thereto. This
                  AGREEMENT is explicitly made subject to the Government's
                  rights under any such agreement and any applicable law or
                  regulation, including P.L. 96-517 as amended by P.L. 98-620.
                  To the extent that there is a conflict between any such
                  agreement, applicable law or regulation and this AGREEMENT,
                  the terms of such Government agreement, applicable law or
                  regulation shall prevail.

         13.3     LICENSEE understands and agrees that BOARD, by this AGREEMENT,
                  makes no representation as to the operability or fitness for
                  any use, safety, efficacy, approvability by regulatory
                  authorities, time and cost of development, patentability,
                  and/or breadth of the LICENSED SUBJECT MATTER. BOARD, by this
                  AGREEMENT, makes no representation as to whether there are any
                  patents now held, or which will be held, by others or by BOARD
                  in the LICENSED FIELD, nor does BOARD make any representation
                  that the inventions contained in PATENT RIGHTS do not infringe
                  any other patents now held or that will be held by others or
                  by BOARD.

         13.4     LICENSEE, by execution hereof, acknowledges, covenants and
                  agrees that LICENSEE has not been induced in anyway by BOARD,
                  SYSTEM, MDA or

                  herein and all other matters pertaining to this Agreement and
                  agrees to accept all risks inherent herein.

                  ability to later assert that right relative to the particular
                  situation involved.

         14.6     Headings included herein are for convenience only and shall
                  not be used to construe this AGREEMENT.

         14.7     If any provision of this AGREEMENT shall be found by a court
                  to be void, invalid or unenforceable, the same shall be
                  reformed to comply with applicable law or stricken if not so
                  conformable, so as not to affect the validity or
                  enforceability of this AGREEMENT.

         14.8     Upon the request of LICENSEE, LICENSOR shall reasonably assist
                  LICENSEE in recording this Agreement in the records of the
