Remarks:
This Form 4/A amends the Forms 4 filed by Mr. Gruverman on March 29, 2004 and April 7, 2004 (the "Original Forms 4").  The Original Forms 4 incorrectly reported that Mr. Gruverman had purchased (a) 80,000 shares through an open-market purchase for a price per share of $1.2375 and an aggregate purchase price of $99,000 and (b) an additional 40,000 shares through an open-market purchase for a price per share of $0.36 and an aggregate purchase price of $14,400.  The Original Forms 4 should have reported that Mr. Gruverman (y) exercised an option to purchase 80,000 shares at a price per share of $1.2375 and an aggregate purchase price of $99,000 and (z) exercised an option to purchase 40,000 shares at a purchase price per share of $0.36 for an aggregate purchase price of $14,400.  Upon review of records, it was discovered that Mr. Gruverman had accidentally exercised 80,000 stock options that had expired prior to the exercise date of 4/7/04 (the "Exercise Date").  The Corporation has agreed to accept the substitute exercise, as of the Exercise Date, of the number of common stock options at the purchase price set forth in the first two entries in Table II (the "Alternative Options"), all of which had previously vested on the Exercise Date, in lieu of the expired options to purchase 80,000 shares.  The aggregate exercise price for the Alternative Options is $55,860.  Instead of repaying to Mr. Gruverman the remaining $43,140 that was paid on the Exericse Date (the "Over-Payment"), Mr. Gruverman and the Corporation have agreed to permit the Corporation to retain the Over-Payment as additional paid in capital (i.e., non-refundable and bearing no interest) on the condition that he be granted a $43,140 credit toward his future exercise of the Corporation's stock options.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
