Dear Shareowner of Harleysville National Corporation:

SUPPORT PROPOSAL #5 TO PROVIDE FOR MAJORITY VOTE IN DIRECTOR ELECTIONS

We are writing to urge you to VOTE FOR PROPOSAL #5 at Harleysville National Corporation’s (Harleysville) April 28, 2009 shareowner meeting. CalPERS is the nation’s largest public pension fund with assets totaling $175 billion and owns approximately 101,000 shares of Harleysville common stock. Proposal #5 is a shareowner proposal asking the Board of Directors to amend the Company’s articles of incorporation and/or bylaws to provide that director nominees shall be elected by the affirmative vote of the majority of votes cast at an annual meeting of shareholders, with a plurality vote standard retained for contested director elections. CalPERS urges Harleysville shareowners to vote “FOR” Proposal #5.

	·	Harleysville stock has underperformed relative to the Russell 1000 Index and its Industry Peer Index over the last 1, 3 and 5 years for the period ending March 31, 2009.

	·	CalPERS believes the Board has failed to adopt current best practices for good corporate governance and has further shown a lack of accountability through the existence of a classified board structure.

Shareowners lack the ability to hold Board members truly accountable for poor performance because of the ease of director re-elections under the current outdated plurality voting structure.

BOARD ACCOUNTABILITY STANDARDS SHOULD APPLY TO COMPANIES OF ALL SIZES

A majority voting standard holds corporate directors accountable for company performance and empowers shareowners to have a say over what is in the best interest of Harleysville. Plurality voting is rapidly being replaced with majority voting in director elections. Approximately 66% of the S&P 500 has adopted some form of majority voting – an indication of the current direction of good corporate governance – and this trend does not apply to large companies alone. Currently, there are a growing number of mid-sized and small companies that are adopting a majority vote standard.
