This is the third amendment to the Schedule 13D previously filed by
the reporting person with respect to the securities of the issuer set forth on
the cover page hereto (such initial filing, together with any prior amendments
thereto, the "Prior Filing"). This amendment is being filed in order to amend
and restate Item 5 of the Prior Filing in its entirety in connection with sales
of the issuer's common stock by affiliates of the reporting person.
ITEM 5. INTEREST IN SECURITIES OF THE ISSUER
(a) By reason of its serving as managing general partner of Nelson and
trading manager of Olympus, Citadel may be deemed to be the indirect
beneficial owner of the Convertible Securities and the shares of
Common Stock into which the Convertible Securities are convertible.
As of the date for the filing of this statement, Nelson and Olympus
collectively owned Convertible Securities for which they originally
paid $950,000 ("Stated Value") and 10,297 shares of Common Stock.
As of any date ("Conversion Date") all or a portion of the Convertible
Securities may be converted into the number of shares of Common Stock
determined by dividing the Stated Value of such securities (plus an
amount equal to 8% interest on the Stated Value of such securities
from the Closing Date) by a conversion price ("Conversion Price").
The Conversion Price is equal to the lesser of (i) $7.00 ("Fixed
Conversion Price") and (ii) 85% of the average closing bid price (as
reported by NASDAQ or such other market or exchange as the Common
Stock is then traded) of the Issuer's Common Stock for the five
trading days immediately preceding the Conversion Date ("Floating
Conversion Price").
If the Company's Common Stock is trading at a price less than $8.24,
the Conversion Price will fluctuate depending upon the closing bid
price of the Issuer's Common Stock. As a consequence, the number of
shares of Common Stock into which the Convertible Securities may be
converted, and consequently the number of shares of such securities
which Citadel may be deemed to beneficially own, may fluctuate on a
daily basis based solely on the Common Stock's market price and
without any action taken by Citadel, Nelson or Olympus.
As of the date for the filing of this statement, by virtue of its
status as the managing general partner of Nelson and the trading
manager for Olympus, Citadel may be deemed to be the beneficial owner
of 536,239 shares of Common Stock representing 4.70% of the Issuer's
Common Stock (based on (i) 10,873,687 shares of Common Stock issued
and outstanding as of November 30, 1996 (as set forth in the Issuer's
most recently filed 10-Q) and (ii) a Conversion Price equal to
$1.9975).
(b) Citadel has the sole power to vote and the sole power to dispose of
the Convertible Securities and the Common Stock into which the
Convertible Securities are convertible on behalf of each of Nelson and
Olympus.
(c) The following transactions with respect to the Issuer's common stock
have been effected during the 61-day period ending January 28, 1997:

(d) Nelson and Olympus, as the direct beneficial and legal owners of the
Convertible Securities, have the right to receive or the power to
direct the receipt of dividends from, or the proceeds from the sale of
the Convertible Securities and the Common Stock into which the
Convertible Securities are convertible. However, Citadel, as managing
general partner of Nelson and trading manager for Olympus, ultimately
has the right to direct such activities.
(e) As of the date for the filing of this statement, Nelson and Olympus
collectively own less than 5% of the Issuer's Common Stock. As a
consequence, from and after such date Citadel shall not be deemed to
be the beneficial owner of more than 5% of the Issuer's Common Stock.
