Item 4.  Purpose of Transaction.

         The Reporting Parties acquired the shares of Common Stock of the Issuer
         as an investment in the Issuer. Although the Reporting Parties have not
         formulated any definitive plans, they may from time to time acquire or
         dispose of Common Stock of the Issuer if and when they deem it
         appropriate. Except as indicated in this Schedule 13D, the Reporting
         Parties currently have no plans or proposals that relate to or would
         result in any to the matters described in subparagraphs (a) through (j)
         of Item 4 of Schedule 13D.

         Mr. Rothschild has been nominated for election to the Board of
         Directors of the Issuer at the Annual Meeting of Shareholders of the

         One-third of the options subject to the grant would vest on the date he
         is first re-elected to the Board by the shareholders; an additional
         5,000 options would vest on the second date that the he is next
         re-elected to the Board by shareholders; and the remaining 5,000
         options would vest on the third date that he is re-elected to the Board
         by shareholders.
_______________________________________________________________________________
Item 5.  Interest in Securities of the Issuer.

         (a) As of the date of this Amendment to Schedule 13D, the Reporting
             Parties beneficially the Issuer's outstanding common stock as
             follows:

                Mr. Rothschild                      264,100 shares     9.7%
                Arterio Inc.                        122,100 shares     4.5%
                Arterio Inc. Profit Sharing Plan     24,500 shares     0.9%

         (b) Mr. Rothschild holds the power to vote and to dispose of all the
             shares reported on this Schedule 13D owned by himself and each of

             bringing the aggregate holdings of the Reporting Parties at that
             time to 162,700 shares (6.1%). This amount represented a change of
             1% from the 5.1% holdings previously reported on Schedule 13D as of
             April 25, 1997, thereby requiring this amendment. Since June 27,
             2000, but not within sixty days of the filing of this Amendment to
