BUFFALO, N.Y., May 12, 2011-- M&T Bank Corporation (NYSE: MTB) ("M&T") announced that all regulatory approvals required under the merger agreement in connection with its proposed acquisition of Wilmington Trust Corporation (NYSE: WL) ("Wilmington Trust") have been received.

M&T recently received approval from the New York State Banking Department, the Delaware Banking Commissioner and the Office of Thrift Supervision, having previously received approval from the Board of Governors of the Federal Reserve System.  As previously announced, Wilmington Trust stockholders approved the merger on March 22, 2011.

The two companies anticipate that the closing of the acquisition will be effective as of 12:01 AM on Monday, May 16th.  The operations of Wilmington Trust, and all of its subsidiaries, will then become part of the M&T Bank Corporation organization.

Immediately following the closing of the acquisition, all Wilmington Trust bank customer accounts will become M&T Bank accounts, but the Wilmington Trust bank branches and ATMs will continue to carry the Wilmington Trust name until such time as a systems conversion is completed, which is expected to occur during the third quarter. During this interim period, Wilmington Trust branches will be operated as a division of M&T Bank.  M&T will continue to conduct the Wilmington Trust Wealth Advisory Services and Corporate Client Services businesses using the Wilmington Trust brand.

"M&T aspires to carry on the mantel that Wilmington Trust long held -- to be the leading provider of credit and financial solutions to businesses and families," said Atwood Collins III, President and COO of M&T Bank's Mid-Atlantic Division.  "We also intend to continue Wilmington Trust's long legacy of generous community support. Delaware will be an important part of M&T, and M&T will be an important part of Delaware."

Subject to the terms of the merger agreement, Wilmington Trust stockholders will receive 0.051372 shares of M&T common stock in exchange for each share of Wilmington Trust common stock they own.  

Through its subsidiary banks, Wilmington Trust Company and Wilmington Trust, FSB, Wilmington Trust operates 55 branches and 225 ATMs with $10.9 billion in assets.

M&T is a financial holding company with $67.9 billion in assets, whose banking subsidiaries, M&T Bank and M&T Bank, National Association, operate branch offices in New York, Pennsylvania, Maryland, Virginia, West Virginia, Delaware, New Jersey and the District of Columbia.  M&T Bank operates more than 725 branches and 1,800 ATMs.
