                  Distributable Profits (as defined in Section 4.3 below) to
                  which they are collectively entitled on a 50/50 basis.

         4.2.     Equity Share.

                  (a)      MR3 shall have the right to acquire up to a 50% share

                           under this Agreement (an "Operating Entity"),
                           provided that MR3 may not acquire an equity share
                           greater than that of Purchaser. The purchase price of
                           any such equity share from Purchaser shall be
                           calculated on the basis of the then book value of
                           such Operating Entity at the time of such purchase.
                           MR3 may effectuate such a purchase of equity from the
                           Purchaser by either assigning all or a part of its

                           all of the equity in such Operating Entity to which
                           MR3 would be entitled under Section 4.2 (a) above,
                           then Purchaser shall immediately distribute to MR3
                           that portion of the equity sale proceeds necessary to
                           equalize the proceeds received by MR3 and Purchaser
                           on a 50/50 basis.

         4.3.     Distributable Profits. Is defined as Net Revenue, less any
                  amounts held in reserve or required to be repaid to third
                  party investors or lenders in connection with the financing of
                  the construction or operation of any facilities necessary to
                  exploit or commercialize the Technology under this Agreement.
                  Net Revenue shall be defined as gross receipts less (i) the
                  sales commissions and expenses from the sale of output from
                  MR3 operations, (ii) Operating Expenses, and (iii) any taxes
                  related hereto. Operating Expenses shall mean all costs and
                  expenses incurred in connection with the acquisition,
                  planning, maintenance, operation, technical support, and
                  management of any facilities utilizing the Technology under
                  this Agreement. Operating Expenses shall not include any costs
                  or expenses incurred by either Purchaser or MR3 which are not
                  directly related to, or allocatable to, the performance of

         11.2.    Remedies of Purchaser. In the event that a court directs
                  Purchaser to cease use of the Technology, MR3 will either (i)
                  modify the Technology so that it is no longer infringing, or
                  (ii) procure for Purchaser the rights necessary for Purchaser
                  to exploit the Technology at no expense to Purchaser. If MR3
                  is unable to comply with either subsection (i) or (ii),
                  Purchaser, at its option may either replace the infringing
                  portions of the Technology with non-infringing technology at
                  MR3's expense, or terminate this agreement and receive a
                  complete refund of the purchase price.
