M&T BANK CORPORATION ANNOUNCES FEDERAL RESERVE BOARD APPROVAL
OF ITS APPLICATION TO ACQUIRE WILMINGTON TRUST CORPORATION

BUFFALO, N.Y. April 26, 2011/PRNewswire/ — M&T Bank Corporation (“M&T”)(NYSE: MTB) announced today that its application to acquire Wilmington Trust Corporation (“WTC”) (NYSE: WL) has been approved by the Board of Governors of the Federal Reserve System. Additional regulatory approvals, including those from the New York State Banking Superintendent and the Delaware Banking Commissioner, are still pending. Subject to the terms and conditions of the merger agreement, M&T expects to close the merger with WTC promptly after receiving the remaining regulatory approvals and after the 15-day waiting period associated with the Federal Reserve Board’s approval order has expired.

As noted at the time the merger with WTC was announced on November 1, 2010, following completion of the merger, M&T expects its capital ratios at the end of the second quarter of 2011 to be comparable to what they were as of September 30, 2010. Pursuant to its capital plan, M&T intends to undertake a series of actions during the second quarter of 2011:

	•		Simultaneous with the closing of the merger, M&T intends to redeem the $330 million of preferred stock that was issued to the U.S. Department of the Treasury (“Treasury Department”) by WTC pursuant to the Troubled Asset Relief Program (“TARP”).
	•		By the end of the second quarter of 2011, M&T intends to repay an additional $370 million of the TARP preferred stock issued to the Treasury Department by Provident Bankshares Corporation and by M&T.
	•		To supplement its Tier 1 capital, M&T will issue $500 million of new perpetual preferred stock prior to the end of the second quarter of 2011.

René F. Jones, M&T’s Executive Vice President and Chief Financial Officer, commented, “We are pleased to have reached another milestone toward completion of our merger with Wilmington Trust. In addition, our planned capital actions will sustain our strong capital base and enable us to continue to meet the credit needs of our consumer and commercial customers throughout the communities we serve.”

Under the terms of the merger agreement, upon closing of the WTC merger, WTC shareholders will receive 0.051372 shares of M&T common stock in exchange for each share of WTC common stock they own. As previously announced by WTC, its shareholders approved the merger on March 22, 2011.
