as an officer, director or affiliate of M&T Bank Corporation (the "Company"),
Forms 3, 4, and 5 in accordance with Section 16(a) of the Securities Exchange
Act of 1934 and the rules thereunder, and any other forms or reports the
undersigned may be required to file in connection with the undersigned's
ownership, acquisition or disposition of securities of the Company; and

(3)do and perform any and all acts for and on behalf of the undersigned which

or other form or reports including any amendment or amendments thereto, and

The undersigned hereby grants to each such attorney-in-fact full power and
