ITEM 1. SECURITY AND ISSUER.
	
This schedule 13D/A relates to the common stock, $.001 par value per share

AMH is the general partner of both Leviticus and Parameter. Adam Hutt is 
the controlling person of AMH.

      Information contained herein with respect to each Reporting Person 
is given solely by such Reporting Person, and no other Reporting Person

ITEM 4. PURPOSE OF TRANSACTION.

The Reporting Persons purchased the Shares for investment purposes. The 
Reporting Persons presently consider the Shares an attractive investment

the Issuer in the open-market or in privately negotiated transactions, 
maintaining their holdings at current levels or selling all or a portion 
of their holdings in the open-market or in privately negotiated 
transactions. Any such actions the Reporting Persons undertake will be 
dependent upon, among other things, the availability of shares
of the Issuer for purchase and the price levels of such shares; general 
market and economic conditions; on-going evaluation of the Issuer's 
business, financial condition, operations and prospects; the relative 
attractiveness of alternative business and investment opportunities; 
the availability of funds for the purchase of additional shares of the 
Issuer; the actions of the management and Board of Directors of the 
Issuer; and other future developments. Although the foregoing reflects 
activities presently contemplated by the Reporting Persons with respect 
to the Issuer, the foregoing is subject to change at any time.
