Safe Harbor Statement This presentation summarizes the financial condition and results of operations for Park National Corporation and its subsidiaries ("Park" or the "Corporation"). This presentation should be considered in conjunction with the consolidated financial statements and related notes and the five- year summary of selected financial data presented in Park’s 2012 Annual Report. Management’s presentation contains forward-looking statements that are provided to assist in the understanding of anticipated future financial performance. Forward-looking statements provide current expectations or forecasts of future events and are not guarantees of future performance. The forward-looking statements are based on management’s expectations and are subject to a number of risks and uncertainties. Although management believes that the expectations reflected in such forward-looking statements are reasonable, actual results may differ materially from those expressed or implied in such statements. Risks and uncertainties that could cause actual results to differ materially include, without limitation: Park's ability to execute its business plan successfully and within the expected timeframe; general economic and financial market conditions, and weakening in the economy, specifically the real estate market and the credit market, either nationally or in the states in which Park and its subsidiaries do business, may be worse than expected which could decrease the demand for loan, deposit and other financial services and increase loan delinquencies and defaults; changes in interest rates and prices may adversely impact the value of securities, loans, deposits and other financial instruments and the interest rate sensitivity of our consolidated balance sheet; changes in consumer spending, borrowing and saving habits; changes in unemployment; asset/liability re-pricing risks and liquidity risks; our liquidity requirements could be adversely affected by changes to regulations governing bank capital and liquidity standards as well as by changes in our assets and liabilities; competitive factors among financial services organizations increase significantly, including product and pricing pressures and our ability to attract, develop and retain qualified bank professionals; the nature, timing and effect of changes in banking regulations or other regulatory or legislative requirements affecting the respective businesses of Park and its subsidiaries, including changes in laws and regulations concerning taxes, accounting, banking, securities and other aspects of the financial services industry, specifically the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), as well as future regulations which will be adopted by the relevant regulatory agencies, including the Consumer Financial Protection Bureau, to implement the Dodd-Frank Act's provisions, the Budget Control Act of 2011 and the American Taxpayer Relief Act of 2012; the effect of changes in accounting policies and practices, as may be adopted by the Financial Accounting Standards Board, the SEC, the Public Company Accounting Oversight Board and other regulatory agencies, and the accuracy of our assumptions and estimates used to prepare our financial statements; the effect of fiscal and governmental policies of the United States federal government; adequacy of our risk management program; a failure in or breach of our operational or security systems or infrastructure, or those of our third-party vendors and other service providers, including as a result of cyber attacks; demand for loans in the respective market areas served by Park and its subsidiaries; and other risk factors relating to the banking industry as detailed from time to time in Park's reports filed with the Securities and Exchange Commission including those described in "Item 1A. Risk Factors" of Part I of Park's Annual Report on Form 10-K for the fiscal year ended December 31, 2012. Park does not undertake, and specifically disclaims any obligation, to publicly release the result of any revisions that may be made to update any forward-looking statement to reflect the events or circumstances after the date on which the forward-looking statement was made, or reflect the occurrence of unanticipated events, except to the extent required by law. 2

Grow quality loans; expand relationships with existing customers E. Implement continued improvements to PRK technology platform F. Improve multiple internal operational processes G.

Why invest in Park National Corporation?  Unique, localized business model makes PNB Affiliates the bank of choice for customers.  History of consistent dividend payments to shareholders and a strong dividend yield.  Favorably positioned to take advantage of growth opportunities in our markets, largely caused by industry dislocation, increased regulation and fatigue.  Park’s short interest position is high compared to both historic levels and the Midwest peer group. As short interest position returns to historic levels, our stock price should react favorably.  Experienced leadership team with proven knowledge of local markets. 36
