                         country during such calendar quarter, provided the

     7.4.  In the event that Elan shall cease to be a shareholder of the
           Company, the Parties shall negotiate in good faith such amendments to
           the Agreement as are equitable and applicable having regard to the
           fact that Elan no longer has any representation on the Board of
           Directors of the Company or the Management Committee and will no
           longer be providing support or funding to the Company provided that
           such negotiations shall not apply to the existence of the Agreement.

     7.5.  Payment of royalties shall be made quarterly within forty-five (45)
           days after the expiry of the calendar quarter. The method of payment
           shall be by way of wire transfer to an account specified by Elan.
           Each payment made to Elan shall be accompanied by a written report,
           prepared and signed by a senior financial officer of the Company. In
           addition the report shall clearly show the Net Sales for the months
           of the calendar quarter for which payment is being made on a country
           by country basis. In the event that no royalty is due to Elan for any
           calendar quarter, the senior financial officer shall so report. In
           addition to the written reports accompanying each payment, the
           Company shall notify Elan, within thirty (30) days of the end of each
           calendar quarter, of the Net Sales of the Elan Royalty Product(s) for
           that preceding quarter on a country by country basis.

     7.6.  The Company shall maintain and keep clear, detailed, complete,
           accurate and separate records so:

           7.6.1.  as to enable any royalties on Net Sales of a Elan Royalty
                   Product which shall have accrued hereunder to be determined;
                   and

           7.6.2.  that any deductions made in arriving at the Net Sales of a
                   Elan Royalty Product can be determined.

     7.7.  All payments due hereunder shall be made in United States Dollars.
           Payments due on Net Sales of the Elan Royalty Product made in a
           currency other than United States Dollars shall first be calculated
           in the foreign currency and then converted to United States Dollars
           on the basis of the exchange rate in effect for the purchase of
           United States Dollars with such foreign currency quoted in the Wall
           Street Journal (or comparable publication if not quoted in the Wall
           Street Journal) with respect to the currency of the country of origin
           of such payment for the day prior to the date on which the payment by
           the Company is being made.

     7.8.  Subject to the provisions of Clauses 7.10 of this Agreement, the
           Company shall pay all royalties at the rates specified in this Clause
           7.

     7.9.  Elan and the Company agree to co-operate in all respects reasonably
           necessary to take advantage of any double taxation agreements or
           similar agreements as may, from time to time, be available.

     7.10. Any taxes payable by Elan on any payment made to Elan pursuant to
           this Agreement shall be for the account of Elan. If so required by
           applicable law any payment made pursuant to this Agreement shall be
           made by the Company after deduction of the appropriate withholding
           tax in which event the Company shall 

                                       14

 
           co-operate to the extent reasonably necessary to obtain the
           appropriate tax credits as soon as is practicable. In the event of a
           credit, the Company shall forthwith forward copies of the credit
           documentation to Elan.

8.   RIGHT OF AUDIT AND INSPECTION

     8.1.  [****] the Company shall permit Elan or its duly authorised
           representatives upon reasonable notice and at any reasonable time
           during normal business hours to have access to inspect and audit the
           accounts and records of the Company and any other book, record,
           voucher, receipt or invoice relating to the calculation of the
           royalty payments on Net Sales submitted to Elan and to the accuracy
           of the reports which accompanied them. Any such inspection of the
           Company's records shall be at the expense of Elan, except that if any
           such inspection reveals a deficiency in the amount of the running
           royalty actually paid to Elan hereunder in any calendar quarter of
           [****] or more of the amount of any running royalty actually due to
           Elan hereunder, then the expense of such inspection shall be borne
           solely by the Company. Any amount of deficiency shall be paid
           promptly to Elan. If such inspection reveals a surplus in the amount
           of running royalty actually paid to Elan by the Company, Elan shall
           promptly inform the Company of the existence of such surplus and
           shall reimburse the Company the surplus. The Company shall maintain
           the foregoing records for a period of at least five (5) years
           following the end of the calendar year to which they pertain.

     8.2.  In the event of any unresolved dispute regarding any alleged
           deficiency or overpayment of royalty payments hereunder, the matter
           will be referred to an independent firm of chartered accountants for
           a resolution of such dispute mutually acceptable to both parties. Any
           decision by the said firm of chartered accountants shall be binding
           on the Parties.

9.   PATENTS

     9.1.  The Company shall permanently mark or otherwise cause any Independent
           Third Party to permanently mark all Elan Royalty Products with the
           patent number(s) in respect of the Elan Patents or otherwise provide
           notice of the existence of the Elan Patents for each country in the
           Territory where sales of the Elan Royalty Products are being made in
           a manner compliant with the applicable laws of such country and in
           such manner as Elan may reasonably request in writing prior to the
           sale or commercial use thereof.

     9.2.  Elan shall be obliged to disclose promptly to the Company inventions
           and discoveries made by or on behalf of Elan relating to the Medipad
           System and any patentable inventions and discoveries within the Elan
           Technology which relate to the Field.

                   patent that may issue covering any improvements). Elan shall
                   have the sole right in its reasonable business discretion to
                   control such filing, prosecution, defence and maintenance;
                   provided however, that the Company shall be provided with

                   described in Clause 9.3.1 in Elan's name and on Elan's
                   behalf, and Elan upon written request from the Company shall
                   execute all documents, forms and declarations and to do all
                   things as shall be reasonably necessary to enable the Company
                   to exercise such option and right:

                   (1)  Elan elects that it does not intend to file patent
                        applications on patentable inventions and discoveries
                        within the Elan Technology except those that relate
                        exclusively outside the Field or patentable improvements
                        developed by or on behalf of Elan in one or more
                        countries in the Territory. Elan shall make such
                        election and so notify the Company in writing at least 2
                        months prior to the expiration of any applicable time

                        of any applicable time bar or other deadline for each
                        patentable invention at least 2 months prior to the

                   Technology).

                   The Company shall have the right to control such filing,

                   sufficient time to review such documents and comment thereon
                   prior to filing of such documents.

           9.4.1.  Except as provided in Clause 11.6, during the Term, the

                   suit or otherwise take action [****] and for its own benefit
                   any such alleged infringements of the Elan Patents or
                   misappropriation of the Elan Know-How, insofar as such

                   sale, importation, manufacture or use of an infusion device
                   for a compound within the Field.

                   In the event that the Company takes such action, the Company
                   shall do so [****]. At the Company's request, Elan will co-
                   operate with such action insofar as the action relates to the
                   Field or the sale, importation, manufacture or use of an
                   infusion device for a compound within the Field [****] for
                   the purpose of this Agreement and prior to commencing, or at

                   within a reasonable period but in any event within [****]
                   after receiving written notice of such alleged infringement

                   being developed or commercialised by Elan or its commercial
                   partners outside the Field, the Parties shall agree as to the

     9.5.  In the event that a claim or proceedings is brought against the

           attorney's fees and expenses), to the extent that such third party
           claim arises or results from, or constitutes a breach by Elan and/or
           EMT of any of the representations or warranties set forth in Clause
           13.4. and provided that the Company has complied with the provisions

          (ii)  information which is made public by the disclosing Party;

          (iii) information which is independently developed by a Party without
                the aid or application of the Confidential Information;

          (iv)  information that is published or otherwise becomes part of the
                public domain without any disclosure by a Party, or on the part
                of a Party's directors, officers, agents, representatives or
                employees;

          (v)   information that becomes available to a Party on a non-
                confidential basis, whether directly or indirectly, from a
                source other than a Party, which source, to the best of the
                Party's knowledge, did not acquire this information on a
                confidential basis; or

          (vi)  information which the receiving Party is required to disclose
                pursuant to:

                (A)  a valid order of a court or other governmental body or any
                     political subdivision thereof or otherwise required by law;
                     or

                (B)  other requirement of law; provided that if the receiving
                     Party becomes legally required to disclose any confidential
                     information, the receiving Party shall give the disclosing
                     Party prompt notice of such fact so that the disclosing
                     Party may obtain a protective order or other appropriate
                     remedy concerning any such disclosure. The receiving Party
                     shall fully co-operate with the disclosing Party in
                     connection with the disclosing Party's efforts to obtain
                     any such order or other remedy. If any such order or other
                     remedy does not fully preclude disclosure, the receiving
                     Party shall make such disclosure only to the extent that
                     such disclosure is legally required.

     10.2.  Any Confidential Information revealed by a Party to another Party
            shall be used by the receiving Party exclusively for the purposes of
            fulfilling the receiving Party's obligations and rights under this
            Agreement and the Development Agreement and for no other purpose.

     10.3.  Each Party agrees to disclose Confidential Information of another
            Party only to those employees, representatives and agents requiring
            knowledge thereof in connection with their duties directly related
            to the fulfilling of the Party's obligations and rights under this
            Agreement. Each Party further agrees to inform all such employees,
            representatives and agents of the terms and provisions of this
            Agreement and their duties hereunder and to obtain their consent
            hereto as a condition of receiving Confidential Information. Each
            Party agrees that it will exercise the same degree of care, but in
            no event less than a reasonable degree,  

                                       20

 
            and protection to preserve the proprietary and confidential nature
            of the Confidential Information disclosed by a Party, as the
            receiving Party would exercise to preserve its own proprietary and
            Confidential Information. Each Party agrees that it will, upon
            request of a Party, return all documents and any copies thereof
            containing Confidential Information belonging to or disclosed by,
            such Party.

     10.4.  Notwithstanding the above, each Party may use or disclose
            Confidential Information disclosed to it by another Party to the
            extent such use or disclosure is reasonably necessary in filing or
            prosecuting patent applications, prosecuting or defending
            litigation, complying with patent applications, prosecuting or
            defending litigation, complying with applicable governmental
            regulations or otherwise submitting information to tax or other
            governmental authorities, conducting clinical trials, or making a
            permitted sub-license or otherwise exercising its rights hereunder,
            provided that if a Party is required to make any such disclosure of
            the other Party's Confidential Information, other than pursuant to a
            confidentiality agreement, such Party shall inform the other Party,
            allow the other Party to participate in the process and generally
            limit disclosure to the greatest extent possible and seek
            confidential treatment or a protective order.

     10.5.  The provisions relating to confidentiality in this Clause 10 shall
            remain in effect during the Term, and for a period of [****]
            following the expiration or earlier termination of this Agreement.

     10.6.  The Parties agree that the obligations of this Clause 10 are
            necessary and reasonable in order to protect the Parties' respective
            businesses, and each Party expressly agrees that monetary damages
            may be inadequate to compensate a Party for any breach by the other
            Party of its covenants and agreements set forth herein. Accordingly,
            the Parties agree and acknowledge that any such violation or
            threatened violation may cause irreparable injury to a Party and
            that, in addition to any other remedies that may be available, in
            law and equity or otherwise, any Party shall be entitled to seek
            injunctive relief against the threatened breach of the provisions of
            this Clause 10, or a continuation of any such breach by the other
            Party, specific performance and other equitable relief to redress
            such breach together with its damages and reasonable counsel fees
            and expenses to enforce its rights hereunder.
