           (b)    Authorization; No Violations.  The execution and delivery of
     this Agreement and the transactions contemplated hereby have been duly
     authorized by the Board of the Company. This Agreement constitutes a legal,
     valid and binding obligation of SIMC enforceable against SIMC in accordance
     with its terms. The execution and delivery of this Agreement by SIMC and
     the performance by SIMC of the transactions contemplated by this Agreement
     do not and will not conflict with or result in a violation, breach or
     termination of, or default under any term or provision of the corporate
     charter or bylaws of SIMC.

          (c)  Title to Assets.  Except as set forth on EXHIBIT 4 SIMC has good,
                                                        ---------

                                       3

     SIMC, prior to the date hereof, SIMC has not been informed in writing that
     those portions of the OpenMotion Technology developed by SIMC personnel do
     not infringe upon the United States patent, copyright or trademark rights
     of any third party, nor do such portions misappropriate the trade secret
     rights of any third party. SIMC has not undertaken any independent
     investigation of the validity or lack of infringement of the intellectual
     property rights of the Transferred Assets.

     SIMC TRANSFERS ITS INTEREST IN AND TO THE OPEN MOTION TECHNOLOGY AND SUCH
     OTHER INTELLECTUAL PROPERTY RIGHTS SET FORTH IN EXHIBIT 2 HERETO "AS IS"

     business, management and financial affairs with Company management and it

     deciding whether to invest in the Series B Preferred Shares. The Series B
     Preferred Shares being issued to SIMC are being acquired for its own
     account for the purpose of investment and not with a view to or for sale in
     connection with a distribution thereof. SIMC understands that (i) the
     Series B Preferred Shares have not been registered under the Securities Act
     by reason of their issuance in a transaction exempt from the registration
     requirements of the Securities Act, (ii) the Shares must be held
     indefinitely unless a subsequent disposition thereof is registered under
     the Securities Act or is exempt from such registration, (iii) the Shares

     on its transfer books to such effect.

liability corporation duly organized, validly existing and in good standing

authority to conduct its business, to admit shareholders to the Company, and to
issue the Series B Shares, and (b) all action required to be taken by the
Company as a condition of the issuance of the Series B Preferred Shares and

hereby shall take place on June 5, 1998 or on such other date as shall be
