Notice: Changing the Annual Meeting of Shareholders Location

Dear Fellow Shareholders,

Due to the emerging public health impact of the coronavirus outbreak (COVID-19) and to support the health and well-being of our partners and shareholders, notice is hereby given that the location of the Annual Meeting of Shareholders of Park National Corporation has been changed. As previously announced, the Annual Meeting will be held on Monday, April 27, 2020 at 2:00 p.m., Eastern Daylight Time (EDT). In light of public health concerns regarding the coronavirus outbreak, the Annual Meeting will be held in a virtual meeting format only. You will not be able to attend the Annual Meeting physically.

As described in the proxy materials for the Annual Meeting previously distributed, you are entitled to participate in the Annual Meeting if you were a registered shareholder as of the close of business on February 28, 2020, the record date, or hold a legal proxy for the meeting provided by your bank, broker, or other nominee if you are the beneficial owner of common shares held in “street name”.

To join the Annual Meeting online at www.virtualshareholdermeeting.com/PRK2020, you must enter the 16-digit number found on the proxy card (if you received or requested paper copies of our proxy materials), voter instruction form or Notice of Internet Availability of Proxy Materials you previously received. You may demonstrate proof of ownership of our common shares and vote during the Annual Meeting by following the instructions available on the meeting website during the Annual Meeting. Whether or not you plan to attend the Annual Meeting, we strongly encourage you to vote and submit your proxy in advance of the meeting by one of the methods described in the proxy materials. The proxy card included with the proxy materials previously distributed will not be updated to reflect the change in location and may continue to be used to vote your common shares in connection with the Annual Meeting.

You may begin to log into the meeting website at 1:45 p.m. EDT. We have worked to offer the same participation opportunities as would be provided at an in-person meeting while further enhancing the online experience available to all Park shareholders regardless of their location. Questions may be submitted online during the Annual Meeting.

By Order of the Board of Directors,

  BRADY T. BURT

Chief Financial Officer, Secretary and Treasurer
