SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Securities Exchange Act of 1934 requires the
Company's officers and directors, and persons who own more than ten percent of a
registered class of the Company's equity securities, to file reports of
ownership and changes in ownership with the Securities and Exchange Commission.
Officers, directors and greater than ten-percent shareholders are required


                                          2


<PAGE>

by SEC regulation to furnish the Company with copies of all Section 16(a) forms
they file.

         Based solely on its review of the copies of such forms received by it,
or written representations from certain reporting persons that no Forms 5 were
required for those persons, the Company believes that, during the period from
March 5, 1996 to September 30, 1996 all filing requirements applicable to its
officers, directors, and greater than ten-percent beneficial owners were
complied with.

(1) All options granted in fiscal 1996 are exercisable in full, commencing June
    3, 1998.  Under the terms of the Company's Stock Option Plan, the
    Compensation Committee retains discretion, subject to plan limits, to
    modify the terms of outstanding options.

(2) All options were granted at fair market value at date of grant.

(3) Realizable values are reported net of the option exercise price.  The
    dollar amounts under these columns are the result of calculations at the 5%
    and 10% rates (determined from the price at the date of grant, not the
    stock's current market value) set by the Securities and Exchange Commission
    and therefore are not intended to forecast possible future appreciation, if
    any, of the Company's stock price.  Actual gains, if any, on stock option
    exercises are dependent on the future performance of the common stock as
    well as the optionholder's continued employment through the vesting period.
    The potential realizable value calculation assumes that the optionholder
    waits until the end of the option term to exercise the option.


         The following table sets forth certain information with respect to
option exercises during 1996 and stock options held by each of the Company's
executive officers as of September 30, 1996.

Item 13 of the Annual Report filed pursuant to Section 13 or 15(d) of the
Securities Exchange Act of 1934 for the fiscal year ended September 30, 1996 is
hereby amended in full as follows:

ITEM 13 - CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         In December 1995, the Company completed a private placement in which
it issued the notes and warrants.  Matthew Mackowski, a director of the Company
and member of the Compensation Committee, purchased $600,000 principal amount of
the notes and warrants to purchase 60,000 shares of Common Stock in such private
placement.  Mr. Mackowski paid an aggregate purchase price of $600,000 for such
securities, consisting of $100,000 in cash and cancellation of $500,000 of
indebtedness owed by the Company to Mr. Mackowski.  In addition, Mr. Mackowski's
father purchased in such private placement $50,000 principal amount of the notes
and warrants to purchase 5,000 shares of Common Stock, for which he paid $50,000
in cash.  In March 1996, the Company repaid the notes with a portion of the
proceeds from its March 1996 initial public offering.

         From time to time, Mr. Mackowski has advanced funds to the Company for
working capital purposes.  The largest amount of such advances outstanding
during fiscal 1996 was $500,000.  These advances were payable on demand and bore
interest of 0.5% above the 90-day treasury bill rate at the date of issuance.
These notes were retired in connection with the private placement described
above.

         Mackowski & Shepler, a private investment partnership of which
Mr. Mackowski is a partner and 50% owner, continues to provide financial and
strategic advisory services to the Company under an arrangement which commenced
in November 1994.  Under this arrangement, Mackowski & Shepler will continue to
receive $7,500 per month until March 31, 1997.  Mackowski & Shepler also
received $50,000 from the Company upon the closing of the Company's initial
public offering for advisory services related to this offering.
