	Know all by these presents, that the undersigned hereby

and Popeo, P.C., signing singly, with full power of substitution, the
undersigned's true and lawful attorney-in-fact to:

(1)	execute for and on behalf of the undersigned, in the
undersigned's capacity as an officer, director and/or 10%
shareholder of the Company, Forms 3, 4, and 5 in
accordance with Section 16(a) of the Securities
Exchange Act of 1934 and the rules thereunder;

(2)	do and perform any and all acts for and on behalf of the
undersigned which may be necessary or desirable to
complete and execute any such Form 3, 4 or 5 and
timely file such form with the United States Securities
and Exchange Commission and any stock exchange or
similar authority; and

(3)	take any other action of any type whatsoever in
connection with the foregoing which, in the opinion of
such attorney-in-fact, may be of benefit to, in the best
interest of, or legally required by the undersigned, it
being understood that the documents executed by such
attorney-in-fact on behalf of the undersigned pursuant to
this Power of Attorney shall be in such form and shall
contain such terms and conditions as such attorney-in-
fact may approve in such attorney-in-fact's discretion

The undersigned hereby grants to each such attorney-in-fact full
power and authority to do and perform any and every act and thing
whatsoever requisite, necessary, or proper to be done in the exercise of
any of the rights and powers herein granted, as fully to all intents and
purposes as the undersigned might or could do if personally present,
with full power of substitution or revocation, hereby ratifying and
confirming all that such attorney-in-fact, or such attorney-in-fact's
