1.       BACKGROUND

         Leiras and TIMERx (formerly Edward Mendell Co., Inc.) are parties to an
         agreement dated July 27th, 1992 (in the following Agreement) and a
         Letter of Agreement signed concurrently with this Letter of Consent,
         concerning, in particular, Leiras' Cystrin (Oxybutynin) product and the
         TIMERx Controlled Release System, and the utilization of a combination
         or combinations thereof and/or of developments thereof. Leiras and
         TIMERx have cooperated in the

                                       -1-

         development and formulation of the Oxybutynin-TIMERx product, which
         programme is now in its final stages. TIMERx has completed its portion
         of the Development Programme, and any further development will be
         conducted by Leiras.

2.       CONSENT TO DISCLOSURES

         In connection with the commercial utilization of Cystrin (Oxybutynin)
         worldwide, Leiras may wish to assign and transfer the product rights
         pertaining thereto, inclusive of the TIMERx element and any
         developments as foreseen or contemplated in the Agreement, in various
         manners and in various territories. Prior to such potential assignments
         and transfers, Leiras may have to disclose relevant and proprietary
         information needed by the potential assignee/transferee for evaluation
         purposes. Such disclosure may also comprise TIMERx elements and, as the
         case may be, key portions of the Agreement. TIMERx hereby gives its
         approval to such disclosures on the condition that the potential
         assignee/transferee enters into a confidentiality agreement basically
         in the form of Appendix A attached as a specimen hereto.

3.       CONSENT TO ASSIGNMENTS AND TRANSFERS

         Should Leiras agree with a potential assignee/transfer on the
         assignment and transfer of the above-mentioned product rights as
         foreseen as a possibility above, such assignment and transfer shall
         take place on the terms and conditions of an agreement basically in the
         form of Appendix B attached as a specimen hereto. TIMERx's approval to
         such assignment(s) and transfer(s) on such terms and conditions, shall
         not be unreasonably withheld unless such assignment and transfer would
         be seriously detrimental to the interests of TIMERx from an objective
         point of view, taking also into consideration Leiras' interest in such
         an assignment and transfer. TIMERx's approval may be withdrawn in the
         thirty (30) day period following the receipt from Leiras of written
         notification of the identity of the potential assignee/transferee.

                  in writing to the defaulting party require the defaulting
                  party to withdraw from this Agreement provided that, in the
                  case of a breach capable of remedy, the defaulting party shall

                  non-payment of monies from the date of such notice to remedy
                  the breach and, if the breach is remedied within such period,
                  the notice shall not take effect.

         termination save for confidentiality obligations and the obligation to
         pay accrued royalties, all of which shall remain in full force and
         effect provided that the termination by either party of this Agreement
         shall be without prejudice to any accrued claims or rights of action
         that either party may have against the other up to the date of such
         termination. Following expiration of the full term of this Agreement,
         the license granted shall become non-exclusive and royalty-free.

8.       FORCE MAJEURE

         If and to the extent that either party is hindered or prevented by
         circumstances not now foreseeable and not within its reasonable ability
         to control from performing any of its obligations under this Agreement
         and promptly so notifies the other party giving particulars of the
         circumstances in question, then the party so affected shall be relieved
         of liability to the other for failure to perform such obligations, but
         shall nevertheless use all reasonable endeavours to resume full
         performance thereof without avoidable delay.

         parties.

         parties hereto.

16.      HEADINGS

         The headings of Clauses shall not affect their interpretation.

17.      EXECUTION IN COUNTERPARTS
