                              DEVELOPMENT FUNDING

1.1  It is estimated that Newco will require an additional U.S.$15,000,000 to
     commence development of the Products based upon the RPI Intellectual
     Property, the Elan Intellectual Property and/or the Newco Technology (the

     "Development Funding").  Within the Development Period, EIS and RPI may
      -------------------
     provide to Newco, by way of an unconditional gift to Newco, as contributed
     surplus or loan, as may be agreed to by EIS and RPI, up to an aggregate
     maximum amount of U.S.$15,000,000, such funding to be provided by EIS and
     RPI to Newco on a pro rata basis based on their respective equity
     interests, on a fully-diluted basis in Newco.

1.2  The Development Funding shall be provided by EIS and RPI, each in its sole
     discretion, at such times as shall be necessary for the development of the
     Products as provided in the Development Plan or as otherwise approved by
     the Newco Directors, including at least one Newco Director designated by
     EIS and one Newco Director designated by RPI.  The Development Funding
     shall be funded on the following terms:

     1.2.1   The minimum amount of each disbursement of the Development Funding
             shall be U.S.$312,500 (except in the event that an amount less than
             U.S.$312,500 remains available for funding, in which case such
             lesser amount may be funded) allocated between EIS and RPI as
             provided in Section 1.1 above;

     1.2.2   Such funding shall be provided in accordance with the Development
             Plan or as otherwise approved by the Newco Board of Directors
             (including at least one Newco Director designated by EIS and at
             least one Newco Director designated by RPI); and

     1.2.3   Such funding shall be subject to the receipt by Elan or EIS of any
             required approvals under the Mergers and Takeovers (Control) Acts
             1978-1996 (the "Irish Mergers Act").
                             -----------------

1.3  In the event that Elan or EIS is unable to obtain approval under the Irish
     Mergers Act within three months after a determination of the necessity of
     such funding by the Newco Directors, the parties hereto shall work together
     in good faith, each in its sole discretion, to agree on an alternative
     funding mechanism.

                                       2
