Item 1.01.    Enter into a Material Definitive Agreement

Item 2.03.    Creation of a Direct Financial Obligation or an Obligation under
              an Off-Balance Sheet Arrangement of a Registrant

On December 9, 2005, the Corporation entered into amendments of its loan
arrangements with Howard S. Modlin, Chairman of the Board and Chief Executive
Officer, and John Segall, a Director. Pursuant to such amendments, an aggregate
of $1,600,000 in secured loans from such directors maturing between September
29, 2005 and September 29, 2006 were extended. Such amendments provided that 50%
of each such amended and restated note was amended to be payable one year from
the original due date and 50% of each such amended and restated note was amended
to be payable two years from the original due date. The conversion features of
four notes held by Mr. Modlin, which were convertible into an aggregate of
1,103,896 shares of Common Stock, and three notes held by Mr. Segall, which were
convertible into an aggregate of 501,698 shares of Common Stock, were
eliminated, and unpaid accrued interest aggregating $230,945.21, was added to
the amended and restated notes. In addition, while interest will continue to
accrue at the rate of 10% per annum from December 9, 2005, the first interest
payment on the amended and restated notes will not commence until May 1, 2006.
In connection with the transactions, Mr. Modlin and Mr. Segall each received
seven year warrants expiring December 8, 2012 to purchase Common Stock at 57-1/2
cents per share covering 2,084,204 shares and 1,100,047 shares, respectively.
The transactions were unanimously approved by the Corporation's Board of
Directors on December 9, 2005.
