able to sell or transfer any of the Shares for an indefinite period of time.

        (10) RESTRICTED SECURITIES. The Investor understands that he may be

Securities Act or applicable Blue Sky Laws.

        (12) RESTRICTIVE LEGEND. The certificates from time to time evidencing

that such transfer may be made without compliance with the registration and
prospectus delivery requirements of the Securities Act and applicable Blue Sky
Laws. Such legal opinion shall be given by counsel satisfactory to the
Corporation, at the Investor's expense.

prospectus delivery requirements of the Securities Act and applicable Blue Sky
Laws. Such legal opinion shall be given by counsel satisfactory to the
