Section 16(a) Beneficial Ownership Reporting Compliance





Section 16(a) of the Securities Exchange Act of 1934 (the Act) requires our officers, directors and persons who own more
than 10% of a class of our securities registered under Section 12(g) of the Act to file reports of ownership and changes in ownership with the SEC. Officers, directors and greater than 10% stockholders are required by SEC regulation to furnish us
with copies of all Section 16(a) forms they file.





Based solely on a review of copies of such reports furnished us and written
representations that no other reports were required during the fiscal year ended September 30, 2002, we believes that all persons subject to the reporting requirements pursuant to Section 16(a) filed the required reports on a timely basis with the
SEC, except Mr. Croft filed late a Form 5 report disclosing one transaction.

Item 13.    Certain Relationships and Related Transactions





In September 2001, a family trust
for which Mr. Elwood G. Norris serves as trustee purchased $250,000 in principal amount of our 12% convertible subordinated promissory notes, and in connection with such purchase, received a warrant to purchase 125,000 shares of our stock. See
Liquidity and Capital Resources above for a more complete description of these securities. The purchase by such trust was on the same terms as those offered to the other purchasers in the same financing. In November 2002, we and a majority of the
holders of such notes agreed to extend the maturity date of the notes, including the note held by Mr. Norris trust, from December 31, 2002 to December 31, 2003.





Under the terms of an Assignment of Technology Agreement dated March 2, 1993 and an Addendum Agreement dated December 2, 1996, we are also obligated to pay Mr. Norris a 2% royalty on net sales from
certain of our technologies, including HSS. The royalty obligation continues until at least March 1, 2007, and for any longer period during which we sell products or license technologies subject to any patent assigned to us by Mr. Norris under this
agreement. We have no present plans to market any of the technologies subject to such agreement other than HSS. No royalties were paid under this agreement in the fiscal year ended September 30, 2002. Because HSS entered commercial production and
sale during the first quarter of fiscal 2003, it is expected that royalties will be paid to Mr. Norris during fiscal 2003. The amount of such royalties will depend on actual sales.
