    The following information amends and supplements the Schedule 13D filed on July 16, 1997 (the "Schedule 13D"), the First Amendment to the Schedule 13D filed on July 17, 2001 (the "First Amendment"), and the Second Amendment to the Schedule 13D filed on September 17, 2001 (the "Second Amendment"). Capitalized terms used but not otherwise defined herein shall have the same meanings assigned to those terms in the First Amendment.

Item 3. Source and Amount of Funds or Other Consideration

    The Second Amendment reported Abbott's agreement to purchase additional shares of Common Stock. Pursuant to that agreement, Abbott has made a payment of $1,000,000 for 126,199 shares of Common Stock of the Issuer (the "Shares"). The source of funds for the Shares is Abbott's general assets.

Item 5. Interest in Securities of the Issuer

    (a)  Abbott may be deemed to be the benefical owner of the Shares of Common Stock to which the Initial Shares and the Additional Shares (as described in the First Amendment) may be converted. Because the conversion price is subject to change, as more fully described in Item 6 of the First Amendment, the actual amount of Common Stock obtained upon conversion may differ from this number. Subject to the foregoing, the shares received upon conversion, together with the Shares and the 500,143 shares of Common Stock described in the Schedule 13D, represent approximately 10.7% of the total outstanding shares of Common Stock. The calculation of the foregoing percentage is based on the number of shares of Common Stock shown as being outstanding on the Form 10-Q Quarterly Report filed by the Issuer with the Securities and Exchange Commission for the quarter ended June 30, 2001.


After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
