M&T Bank, the principal banking subsidiary of M&T Bank Corporation , announced today that on December 7, 2007 it completed the acquisition of First Horizon National Corp.'s First Horizon Bank Mid-Atlantic retail banking franchise.

Twelve former First Horizon Bank branches are reopening today as branches of M&T Bank. Ten of the branches are located in the Greater Washington region, and two are in Greater Baltimore. As a result of the acquisition, customers now have access to 56 branches and 95 ATMs in the Greater Washington market and 76 branches and 252 ATMs in Greater Baltimore.

All accounts and balances have been transferred from First Horizon Bank, and new checks and ATM cards have been sent to former First Horizon Bank customers. Rates and terms have not been changed on CDs, installment loans, lines of credit or overdraft protection accounts.

"Our new customers will find the same friendly and experienced associates and a wider network of branches and ATMs to choose from, and our new employees will find that M&T Bank is deeply committed to their success and to the success of the customers and communities we serve," said Atwood "Woody" Collins III, President of M&T's Mid-Atlantic Division.

"This is a tremendous opportunity to expand our presence in the Mid- Atlantic region, a dynamic and important market for our company," Collins added. "The transaction expands our branch and ATM network, adds new deposit, loan and investment balances and gives us new customers to serve."

M&T Bank Corporation is a bank holding company with approximately $63.8 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. As a result of this acquisition, M&T Bank now operates 704 branches and more than 1,600 ATMs.
