upon independent investigation made by it and has not relied on any
information or representations made by third parties.  Seller understands
that the Shares have not been registered under the Securities Act or
under  state securities laws and therefore it cannot dispose of any or

as the parties shall agree to in writing (the "Closing Date").  Title to,
ownership of, control over, and risk of loss of, the Assets shall pass to
