Park National Corporation makes correction
to 2006 earnings announcement

NEWARK, Ohio— Park National Corporation (Park) (AMEX:PRK) today reported a correction to net income for the fourth quarter and for the full year of 2006, which had previously been reported in Park’s news release issued on Tuesday, January 16, 2007. Park’s net income (as a result of the correction) decreased by $1.256 million for both the three- and twelve-month periods ended December 31, 2006, as compared to Park’s net income reported in the January 16, 2007 news release.

For the full year of 2006, Park’s net income was $94.091 million or $6.74 per diluted share, compared to that reported in the previous news release (from January 16, 2007) which had reported net income of $95.347 million and $6.83 per diluted share. This correction of $1.256 million resulted in a 1.3 percent decrease in both previously reported net income and previously reported diluted earnings per share for 2006.

Park’s net income for the year ended December 31, 2006 (as corrected), decreased by $1.147 million or 1.2 percent to $94.091 million compared to $95.238 million for 2005. Park’s diluted earnings per share increased by $.10 per share or 1.5 percent to $6.74 in 2006 (as corrected) compared to $6.64 for 2005.

For the fourth quarter of 2006, Park’s net income was $22.593 million or $1.63 per diluted share, compared to that reported in the previous news release (from January 16, 2007) which had reported net income of $23.849 million or $1.72 per diluted share. This correction of $1.256 million, resulted in a 5.3 percent decrease in previously reported net income and a 5.2 percent decrease in previously reported diluted earnings per share for the fourth quarter of 2006.

Park’s net income for the fourth quarter of 2006 (as corrected), decreased by $238,000 or 1.0 percent to $22.593 million compared to $22.831 million for the fourth quarter of 2005. Park’s diluted earnings per share increased by $.02 or 1.2 percent to $1.63 for the fourth quarter of 2006 (as corrected) compared to $1.61 for the fourth quarter of 2005.

Earlier this week, Park’s management discovered that the accrued interest receivable balance for loans was overstated by $1.933 million due to interest income being accrued on certain previously charged-off loans. When a loan is charged-off, the loan balance is reduced to zero and a charge is made to the loan loss reserve. No additional interest income is to be accrued on charged-off loans. However, for this to be properly reflected within Park’s data processing system, the charged-off loan also needs to be coded as being nonaccrual. Primarily, one of Park’s subsidiary banks did not code charged-off installment loans within Park’s data processing system as nonaccrual. This

error started approximately 10 years ago and resulted in an overstatement on a cumulative basis of $1.933 million for both accrued interest receivable on loans and interest income on loans. Park recorded this cumulative adjustment in the fourth quarter of 2006. This reduction in interest income on loans of $1.933 million caused a reduction in federal income tax expense of $677,000, which resulted in the decrease in net income of $1.256 million.

Park’s management has determined that the amount by which accrued interest receivable on loans and the related interest income on loans was overstated is not material to any previously issued financial statements. Accordingly, Park has recorded the cumulative adjustment of $1.933 million in the fourth quarter of 2006 and has not restated any previously issued financial statements. Management estimates that the impact on interest income on loans for the previous several quarters was an overstatement of approximately $100,000 per quarter. This overstatement had no impact on Park’s customer accounts or Park’s assets, other than accrued interest receivable on loans.

Headquartered in Newark, Ohio, Park holds $5.47 billion in assets (based on asset totals as of December 31, 2006). Park and its subsidiaries consist of 12 community banking divisions and two specialty finance companies, all based in Ohio. Park operates 138 offices across 29 Ohio counties and one Kentucky county through the following organizations: The Park National Bank, The Park National Bank of Southwest Ohio & Northern Kentucky Division, Fairfield National Division, The Richland Trust Company, Century National Bank, The First-Knox National Bank of Mount Vernon, Farmers and Savings Division, United Bank, N.A., Second National Bank, The Security National Bank and Trust Co., Unity National Division, The Citizens National Bank of Urbana, Scope Leasing, Inc., and Guardian Financial Services Company.
