in connection with any such transaction is fair to the holders of shares of the
Common Stock and (ii) the consideration to be paid in connection with such
transactions shall consist solely of cash, cash equivalents or publicly traded

recognized investment banking firm selected by the party other than the
Recommending Party (and compensated by the Company) confirming that the
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)
shall, to the extent permitted by applicable law and subject to the fiduciary
duties of the members of the Board of Directors who were not designated by the
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 


                                      -6-

event that David M. Phillips shall voluntarily resign from the Board of
Directors, die or become Disabled.

            4.4.  ADDITIONAL COVENANT TO VOTE. White River agrees that in the

     proposed Disposition and (ii) if reasonably requested by the Company, a 
     written opinion of legal counsel, who shall be reasonably satisfactory

     satisfactory to the Company, to the effect that the proposed Disposition 
     may be effected without registration under the Securities Act and any 
     applicable state securities laws.

shares of Common Stock then outstanding; and (C) such Disposition occurs after
