Section 8 – Other Events

Item 8.01. Other Events

On March 5, 2010, Harleysville National Corporation’s wholly-owned subsidiary, Harleysville National Bank and Trust Company (the “Bank”), was advised by the Office of the Comptroller of the Currency (the “OCC”) that it has extended the deadline by which the Bank must meet certain individual minimum capital ratios established by the OCC and disclosed on a Form 8-K filed June 8, 2009 from March 31, 2010 to May 31, 2010. The OCC had previously extended the Bank’s compliance deadline from June 30, 2009 to March 31, 2010.

The extension for compliance is conditioned upon the Bank maintaining capital ratios at least equal to those of a “well capitalized” bank under applicable regulations and the Bank’s continuing progress in addressing certain concerns raised by the OCC in its most recent examination of the Bank.

Harleysville National Corporation expects that its planned merger with First Niagara Financial Group, Inc. will close early in the second quarter of 2010, pending and subject to the receipt of all required regulatory approvals.

Forward Looking Statements

Except for historical information, all other information in this filing consists of forward-looking statements. These forward-looking statements involve a number of risks, uncertainties and other factors that may cause actual results to be materially different from those expressed or implied in the forward-looking statements. Important factors that could cause the statements made to differ include that the proposed merger between Harleysville National Corporation and First Niagara Financial Group, Inc. is subject to a number of conditions and approvals, including regulatory approvals, the receipt of which is required to close the merger. Other important factors are discussed under the caption “Forward-Looking Statements” in Harleysville National Corporation’s Form 10-K Annual Report for the year ended December 31, 2008 and in subsequent filings made prior to or after the date hereof.
