NEWARK, Ohio — The Park National Corporation (“Park”) (AMEX:PRK) today announced earnings for the first quarter of 2005. Net income for the first quarter of 2005 totaled $23.342 million or $1.61 per diluted share, compared to net income of $22.978 million or $1.58 per diluted share in the same period of 2004, increases of 1.58 percent in net income and 1.90 percent in earnings per diluted share.

Park’s Board of Directors declared a cash dividend of $0.90 per share payable to stockholders of record as of May 24, 2005. The dividend will be paid on June 10, 2005.

The Park National Bank, a Park subsidiary, recently announced three office location changes resulting from growth in customer demand in metropolitan areas.

Also, the bank’s Dayton office, led by Doug Compton, focuses on the needs of business owners and is moving from a small suite in downtown Dayton to a building near Centerville. In May, the bank’s Worthington office (Franklin County), under the leadership of Mike Shannon, will move from a suite on the second floor of an office building into a newly constructed 12,000-square-foot building owned by the bank and featuring drive-through lanes and an ATM.
