Explanation of Responses:

1. The reported transaction involved the automatic exercise of a stock option by M&T Bank Corporation pursuant to an Administrative Rule for Stock Award Grants approved by the Nomination, Compensation and Governance Committee of the Board of Directors of M&T Bank Corporation on November 16, 2010. Pursuant to this Administrative Rule, the reporting person's stock option that was set to expire on January 16, 2012 was automatically exercised on January 13, 2012, the last business day preceding the expiration date, and M&T Bank Corporation withheld an amount of M&T Bank Corporation common stock from the stock option having a fair market value equal to the sum of the exercise price and any amounts required to be withheld for tax purposes and issued the net shares to the reporting person.

2. Includes 27.5123 shares acquired between April 1, 2011 and January 3, 2012 through the reporting person's participation in a dividend reinvestment plan meeting the requirements of Rule 16a-11.

3. Currently exercisable.

4. 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.

5. 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.

6. The information presented is as of December 30, 2011.
