SECOND AMENDMENT TO CREDIT AGREEMENT

This SECOND AMENDMENT TO CREDIT AGREEMENT (this “Amendment”), made and entered into as of May 17, 2018, is by and between PARK NATIONAL CORPORATION,

a corporation organized under the laws of the State of Ohio (the “Borrower”), and U.S. BANK

NATIONAL ASSOCIATION, a national banking association (the “Bank”).

RECITALS

1.The Bank and the Borrower entered into a Credit Agreement dated as of May 18, 2016, and a First Amendment to Credit Agreement entered into as of June 15, 2017 (as amended, the “Credit Agreement”); and

2.The Borrower desires to amend certain provisions of the Credit Agreement, and the Bank has agreed to make such amendments, subject to the terms and conditions set forth in this Amendment.

AGREEMENT

NOW, THEREFORE, for good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto hereby covenant and agree to be bound as follows:

Section 1.    Capitalized Terms. Capitalized terms used and not otherwise defined herein shall have the meanings assigned to them in the Credit Agreement, unless the context otherwise requires.

Section 2.    Amendments. The Credit Agreement is hereby amended as follows:

2.1.Section 1.1 of the Credit Agreement is amended by amending the definition of “Revolving Loan Maturity Date” in its entirety to read as follows:

“Revolving Loan Maturity Date”: August 16, 2018.

Section 1.1 of the Credit Agreement is further amended by adding the following definition thereto in the proper alphabetical order:

“Prime Rate”: A rate per annum equal to the greater of (i) zero percent (0.0%) and (ii) the prime rate of interest announced from time to time by the Bank or its parent (which is not necessarily the lowest rate charged to any customer), changing when and as said prime rate changes.

2.2.Interest on Loans. Section 2.4(a) of the Credit Agreement is amended in its entirety to read as follows:

(a)Interest Rate. Interest on each Revolving Loan shall accrue at an annual rate equal to the Applicable Margin plus the greater of (i) zero percent (0.0%) and

(ii) the one-month LIBOR rate quoted by Bank from Reuters Screen LIBOR01

Page or any successor thereto, which shall be that one-month LIBOR rate in effect two New York Banking Days prior to the Reprice Date, adjusted for any reserve requirement and any subsequent costs arising from a change in government regulation, such rate rounded up to the nearest one-sixteenth percent and such rate to be reset monthly on each Reprice Date. The term “New York Banking Day” means any date (other than a Saturday or Sunday) on which commercial banks are open for business in New York, New York. The term “Reprice Date” means the first day of each month. If the initial Revolving Loan under this Agreement is made other than on the Reprice Date, the initial one-month LIBOR rate shall be that one-month LIBOR rate in effect two New York Banking Days prior to the date of the initial advance, which rate plus the percentage described above shall

be in effect until the next Reprice Date. Notwithstanding the foregoing, in the event the Bank determines (which determination shall be conclusive absent manifest error) that (A) the interest rate applicable to the Revolving Loans is not ascertainable or does not adequately and fairly reflect the cost of making or maintaining the Revolving Loans and such circumstances are unlikely to be temporary, (B) ICE Benchmark Administration (or any Person that takes over the administration of such rate) discontinues its administration and publication of interest settlement rates for deposits in Dollars, or (C) the supervisor for the administrator of such interest settlement rate or a governmental authority having jurisdiction over the Bank has made a public statement identifying a specific date after which such interest settlement rate shall no longer be used for determining interest rates for loans, then the Bank shall determine an alternate rate of interest to the LIBOR rate described above that gives due consideration to the then prevailing market convention for determining a rate of interest for comparable bank-originated commercial loans in the United States at such time and, if necessary, the Bank and the Borrower shall enter into an amendment to this Agreement to reflect such alternate rate of interest and such other related changes to this Agreement as may be applicable. Such alternate rate shall be adjusted for any reserve requirement and any subsequent costs arising from a change in government regulation. Until an alternate rate of interest shall be determined in accordance with this Section 2.4(a), interest on each Revolving Loan hereunder shall accrue at the Prime Rate plus the Applicable Margin. If the alternate rate of interest determined pursuant to this Section 2.4(a) shall be less than zero, such rate shall be deemed to be zero for the purposes of this Agreement. The Bank's internal records of applicable interest rates (including without limitation the Bank’s designation of any successor interest rate index if the rate index described above shall become temporarily unavailable) shall be determinative in the absence of manifest error.

Section 3.    Effectiveness of Amendment. The amendments in this Amendment shall become effective upon delivery by the Borrower of, and compliance by the Borrower with, the following:

3.1.This Amendment duly executed by the Borrower.

3.2.A certificate of a Secretary or Assistant Secretary of the Borrower dated as of the date of this Amendment (the "Certificate") and certifying as to the following:

(a)The Borrower’s Resolutions of the Executive Committee of the Board of Directors of the Borrower duly adopted on May 6, 2016 (the “Resolutions”), remain in full force and effect and are sufficient to authorize this Amendment by the Borrower and its execution and delivery by officers of the Borrower, and there has been no change in or revocation of the authority granted to the officers of the Borrower therein.

(b)The Certificate contains the incumbency, names, titles, and signatures of the Borrower’s officers authorized to execute this Amendment, on behalf of the Borrower.

(c)There has been no amendment to the Borrower’s articles of incorporation or code of regulations since true and accurate copies thereof were delivered to the Bank with an Officer’s Certificate of the Borrower dated May 18, 2016.

3.3.A good standing certificate from the Secretary of State of the State of Ohio dated not more than 30 days prior to the date of this Amendment.

3.4.The Borrower shall have satisfied such other conditions as specified by the Bank, including payment of all unpaid legal fees and expenses incurred by the Bank through the date of this Amendment in connection with the Credit Agreement and the Amendment Documents (as defined below).

(b)there will exist no Default or Event of Default under the Credit Agreement as amended by this Amendment on such date that the Bank has not waived.

This Amendment, from and after the date hereof, embodies the entire agreement and understanding between the parties hereto and supersedes and has merged into this Amendment all prior oral and written agreements on the same subjects by and between the parties hereto with the effect that this Amendment shall control with respect to the specific subjects hereof and thereof.
