Explanation of Responses:

1. The reported transaction involves a transfer of securities by gift for which no payment of consideration was received by the reporting person.

2. The GRATs (see (5) below), the West Ferry Foundation (see (8) below), the Roche Foundation (see (7) below), the St. Simon Charitable Foundation (see (9) below), the Interlaken Foundation (see (2) in the reporting person's second of two filings today) and the reporting person are members of a "group," as such term is used in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended, which claims beneficial ownership of more than 5% of the outstanding shares of the Common Stock of M&T Bank Corporation. The reporting person, as a Trustee of the West Ferry Foundation and the GRATs, and as a director and President of each of the Roche Foundation, the St. Simon Charitable Foundation and the Interlaken Foundation previously filed Form 3 reports on behalf of the West Ferry Foundation, the Roche Foundation, the St. Simon Charitable Foundation, the Interlaken Foundation and each GRAT. (Please note that footnote (2) is continued in footnote (3) due to system limitations.)

3. (Please note that footnote (3) is a continuation of footnote (2).) The holdings of and transactions in the Common Stock of M&T Bank Corporation for the West Ferry Foundation, the Roche Foundation, the St. Simon Charitable Foundation, the Interlaken Foundation and each GRAT are reported in the reporting person?s individual Form 4 report in reliance on the Commission staff?s position in D?Ancona & Pflaum (February 18, 1992). Separate reports therefore are not filed on behalf of the West Ferry Foundation, the Roche Foundation, the St. Simon Charitable Foundation, the Interlaken Foundation or either GRAT.

4. The information presented is as of December 31, 2004.

5. The indicated shares are held by Grantor Retained Annuity Trusts No's. 5 and 6, respectively, under indentures dated July 23, 1993 (individually, a "GRAT" and collectively, the "GRATs"). The reporting person is a trustee of each GRAT and holds sole voting and dispositive power over the shares held by the GRATs.

6. The indicated shares are held by a limited liability company of which the reporting person is the sole member.

7. The indicated shares are held by the Roche Foundation, a Delaware not-for-profit, non-stock corporation in which the reporting person has no pecuniary interest. The reporting person is the sole director and president of the Roche Foundation and holds sole voting and dispositive power over the shares held by it.

8. The indicated shares are held by the West Ferry Foundation, a charitable trust in which the reporting person has no pecuniary interest. The reporting person is the trustee of the West Ferry Foundation and holds sole voting and dispositive power over the shares held by it.

9. The indicated shares are held by the St. Simon Charitable Foundation, a Delaware not-for-profit, non-stock corporation in which the reporting person has no pecuniary interest. The reporting person is a director and President of the St. Simon Charitable Foundation and holds voting and dispositive power over the shares held by it.

10. The reported transaction involves a transfer of securities by gift for which no consideration was paid.

11. Currently exercisable.

12. The option was granted under an employee stock option plan maintained by M&T Bank Corporation, and therefore the reporting person paid no price for the option.

13. The reported phantom common stock units are held by the reporting person in an excess benefit plan account maintained by M&T Bank Corporation and represent a like number of shares of M&T Bank Corporation Common Stock. The phantom common stock units may only be settled in cash upon distribution in accordance with the terms of the plan. The reported phantom common stock units also include units acquired through the dividend reinvestment feature of the plan.

Remarks:

This is the first of two Form 4 filings by the reporting person to report the reporting person's transactions that occurred on January 18, 19 and 20, 2005. Multiple Form 4 filings are required due to SEC system limitations that do not allow more than 30 transactions to be reported in Table I.
