Dear Xxx:

         This will confirm that we have agreed to defer payment of an additional
$160,000 in fees due to us until January 2, 2005, except for payments out of
future profits or the net proceeds of equity financings.

         This will further inform that the $160,000 balance of the amount
deferred last year until January 2, 2003 (after giving effect to a $90,000
payment in restricted shares of Common Stock), is now deferred until January 2,
2005 except for payments out of future profits or the net proceeds of equity
financings, provided that it does not impact operations.


                                                              Very truly yours,




                                                              Xxxxxxx X. Xxxxxxx
