ITEM 1.01    ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT
-------------------------------------------------------

             On August 4, 2005, the Registrant and David C. Kahn entered into an
agreement (the "Agreement") pursuant to which Mr. Kahn agreed to continue to
serve as Chief Financial Officer of the Registrant through December 31, 2006. In
consideration for his services, Mr. Kahn will be compensated at the rate of
$6,000 per month for the period through December 31, 2005 and $6,300 per month
for the year ended December 31, 2006. Mr. Kahn was also issued a ten year option
(the "Option") to purchase 75,000 shares of the Registrant's common stock at an
exercise price of $.80 per share. The option vested 30,000 shares on the date of
grant and the balance of the shares (45,000) will vest on a quarterly basis in
equal amounts of 7,500 shares beginning September 30, 2005 through December 31,
2006. Upon a "Change in Control" (as defined) all of the unvested shares
underlying the Option shall become 100% vested and immediately exercisable.

             The Agreement further provides that the Registrant may terminate
the Agreement at any time for any reason. In the event Mr. Kahn's services are
terminated without "Good Cause" (as defined), he will be entitled to accelerated
vesting of all unvested shares underlying the Option and the lesser of six
months base monthly compensation or the remaining balance of the monthly
compensation payable through December 31, 2006.
