     Sale") of greater than 50% of the outstanding common stock and common stock
     equivalents (on a fully diluted basis) in the Company or Buyer (or any
     affiliate of Buyer which includes an part of its consolidated operations
     the business of the Company (a "Sale Affiliate")) and the sale (an "Asset
     Sale") of all or substantially all of the assets of the Company, Buyer or
     Sale Affiliate, are referred to herein together as a "Sale". If a Sale

     subject to the condition that each Selling Shareholder acknowledge and
     agree that (i) the Paying Agent (Douglas Campbell) is specifically
     authorized and empowered in his sole discretion (and without any further
     action on the part of any other Selling Shareholder) to agree to a further

     Selling Shareholder without registration thereof pursuant to applicable
     federal and state securities laws. Each Selling Shareholder specifically
     acknowledges that it understands and agrees to the foregoing and, further,
     that Paying Agent, as attorney-in-fact of each Selling Shareholder pursuant

     Agreement) is specifically authorized as Attorney-in-Fact for each selling
     Shareholder pursuant to the provisions of the Paying Agent Agreement,
     including Section 5.9 thereof, and this amendment to agree to any such
     further amendment to the Agreement in the name of and for and on behalf of

                 1.7.7    Liquidity Event. Each of the Company's purchase of the
                          ---------------                                       
     Continuing Shares as a result of a Sale or an IPO, and the Early Redemption
     shall be a "Liquidity Event" under the Agreement.

                 1.7.8    Further Amendments. Notwithstanding any other
                          ------------------
     provision of this Agreement, if any subsequent amendment or amendments to
     this Agreement are proposed and Parent, Buyer and Selling Shareholders
     holding not less than 90% of the Continuing Shares agree thereto by
     execution of a writing setting forth such amendment, such amendment shall
     be binding on all of the parties hereto, including all Selling
     Shareholders, whether or not they specifically consent thereto or execute
     the writing setting forth the amendment. Each Selling Shareholder
     acknowledges and agrees that the Selling Shareholders, interests are
     substantially aligned and that requiring each Selling Shareholder to
     specifically approve an amendment is cumbersome and may adversely impact
     the interests of the Selling Shareholders as a group."

Shares (referred to in the Agreement as the Escrowed Continuing Shares) are, by

Powers as provided in the Paying Agent Agreement.  The instruction to the Share
Escrow Holder herein shall for all purposes be a joint Certification of Buyer
and Shareholder Representative to Share Escrow Holder, as contemplated under
Section 1.7.2.1 of the 1995 Agreement, and the Share Escrow Holder is, on
release and delivery of the Escrowed Continuing Shares as provided above,
released and discharged of any claim or liability relating to or arising cut of
Share Escrow Holder's acting as such under the Agreement.
