     On a pro forma basis, Huntington will have 756 offices, 1,384 ATMs, and deposits of approximately $38 billion as of September 30, 2006. In Ohio, Huntington will operate 449 offices, 819 ATMs, with deposits of approximately $25 billion as of September 30, 2006, on a pro forma basis.

     The merger was unanimously approved by both companies’ boards of directors. It is expected to close early in the 2007 third quarter, pending customary regulatory approvals, as well as the approval of Huntington’s and Sky Financial Group’s shareholders.

     “This merger is consistent with our conviction that Huntington can create shareholder value by participating in consolidation in the Midwest and lowering costs and increasing customer convenience,” said Thomas E. Hoaglin, Huntington’s chairman, president, and chief executive officer. “Importantly, it provides significant benefits to Huntington’s shareholders and customers. For shareholders, this transaction is immediately accretive to 2007 earnings and is expected to add 4% to earnings in 2008. Further, the value of the expense efficiencies that can be gained will exceed the premium we are paying.”

We will also become the third largest bank in Indianapolis, one of the faster growing Midwest markets. In addition, Sky Financial Group provides entry into new markets including Western Pennsylvania

and Pittsburgh. We look forward to welcoming Sky Financial Group’s customers and associates to the Huntington family.”

     “Retaining Sky Financial Group’s customers and local management are key objectives,” Hoaglin noted. “We have known Sky’s senior executives for a number of years and their addition strengthens Huntington’s overall management team. A hallmark of Sky has been their success in developing a strong sales culture, and we expect to leverage this expertise. Their culture of local-decision making and their customer base are similar to our own. We also share a passion for community involvement, and this merger will provide additional resources that can be delivered locally.”

     Also commenting on the transaction, Marty Adams, Sky Financial Group’s chairman, president, and chief executive officer, said, “This is an exciting transaction that provides Sky shareholders with immediate value, as well as the opportunity to participate in the upside potential created by bringing together our two strong financial institutions. Both companies have deep-rooted ties to the communities in which we operate and share a commitment to delivering the best products and services to our customers locally. We expect this transaction to benefit our loyal customers significantly by giving them added convenience and access to Huntington’s many services, including its proven wealth and investment management expertise.”

     Adams continued, “This is an important day in the history of Sky Financial, and on behalf of our board and management, I want all of our employees to know how much we recognize and appreciate the integral role they have played in our growth and success.”

     Hoaglin and Adams noted that they are committed to a seamless transition for Sky Financial Group’s customers. Huntington and Sky Financial will initiate an extensive communication outreach program to ensure that all customers are informed prior to any changes resulting from the merger.
