Park National Corporation reports an expected increase
in net loan charge-offs for fourth quarter 2007

NEWARK, Ohio — Park National Corporation (Park) (AMEX:PRK) announced today it expects to report approximately $12 million in net loan charge-offs for the fourth quarter of 2007. Park affiliate Vision Bank, which operates in the Florida panhandle and the eastern gulf coast of Alabama, accounts for approximately $7 million of the estimated net loan charge-offs. Park’s 12 Ohio-based banking subsidiaries and divisions account for approximately $5 million of the estimated net loan charge-offs. Approximately $9 million of the estimated total net loan charge-offs is attributable to commercial real estate and other commercial loans. The remaining $3 million of estimated net loan charge-offs pertain primarily to consumer installment loans.

Annualized net loan charge-offs for the nine months ended September 30, 2007 were 0.37 percent as a percentage of average loans, whereas annualized net loan charge-offs for the fourth quarter of 2007 will likely be 1.15 percent of average loans. For the first three quarters of 2007, net loan charge-offs totaled $10.9 million, $2.2 million from Vision Bank and $8.7 million from Park’s Ohio affiliates. Park’s allowance for loan and lease losses as a percentage of loans was 1.91 percent at September 30, 2007.

Park’s net income for the first three quarters of 2007 was $65.9 million, with a loan loss provision of $10.9 million for the same period. Park estimates a loan loss provision of approximately $12 million for the fourth quarter 2007.

According to Park Chairman C. Daniel DeLawder, the increase in the loan loss provision is a result of asset value deterioration in Vision Bank’s loan portfolio and specific credit problems (mostly due to general market conditions) in Ohio. “Our standard loan administration process worked effectively and alerted us to potential problems which we’ve taken immediate steps to address. These are common issues in our industry currently and we choose to be proactive and aggressive in our efforts to recognize potential losses,” he explained.

Park lenders are working diligently in Florida, Alabama, and Ohio to strengthen particular loan quality deficiencies. Park will continue to work actively with borrowers as challenges emerge.

“Many economic factors that impact asset valuation are outside our control, and we continue to learn from current economic circumstances. We have high confidence in our system for detecting problem loans. Early detection, coupled with our experienced lenders, will help us minimize ultimate loan losses in the future,” DeLawder said.

“We continue to possess a strong regulatory capital base, and we remain very committed to all the communities served by our banks,” he said.
