consideration to be paid in connection with any such transaction is fair to the
holders of shares of Common Stock, the members of the Board of Directors
designated by the parties hereto shall to the extent permitted by applicable law
and subject to their fiduciary duties, approve such merger, consolidation or
sale.

            4.3.  CONTROL OF SUBSEQUENT OFFERINGS. A majority of the directors
designated by the Inside Stockholders pursuant to Section 3.1(a) or 3.1(b)

Inside Stockholders, be delegated the authority of the Board of Directors with
respect to the timing, price and other terms of each Subsequent Offering;
PROVIDED, HOWEVER, the Company shall not consummate a Subsequent Offering (i)
unless the Company can demonstrate to the reasonable satisfaction of White River
that after giving effect to the Subsequent Offering the Company would have funds
legally available to redeem shares of the
