"Company"), Forms 3, 4, and 5 and amendments thereto 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 any amendments thereto and timely

file such forms with the United States Securities and Exchange

Commission (the "SEC") and any stock exchange or similar authority,

including, but not limited to, taking any actions necessary or

desirable in connection with effectuating electronic filings; and (3)

take any other action of any type whatsoever which, in the opinion of

such attorney-in-fact, may be necessary or desirable in connection with

the foregoing authority, 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

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

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney

to be executed as of this  22nd     day of August, 2005.
