Change in Control Agreement, dated April 5, 2017, by and between Origin Bank, Origin Bancorp, Inc. and F. Ronnie Myrick

THIS AGREEMENT is made as of the 5^th day of April, 2017, by and among ORIGIN BANK, a banking institution organized under the laws of the state of Louisiana (the “Bank”); its corporate parent, ORIGIN BANCORP, INC., a corporation organized and existing under the laws of the State of Louisiana (“ORIGIN”); and F. Ronnie Myrick (“Executive”).

WHEREAS, Executive is employed by the Bank or ORIGIN as Chairman/Chief Administrative Officer and Senior Executive Vice President;

WHEREAS, the Bank and ORIGIN desire to attract and retain well-qualified executives and key personnel and to incentivize such personnel to remain in the employ of the Bank; and

WHEREAS, the Bank and ORIGIN recognize that Executive is a valuable resource and desire to assure Executive’s employment, continued loyalty and services and, in the event Executive is terminated or Executive’s position with the Bank or ORIGIN is adversely changed as a result of a Change in Control (as hereinafter defined) of the Bank or ORIGIN, to assure Executive of adequate severance.

NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

In order for Executive to be eligible for payment of the benefits under Section 4 of this Agreement, Executive must be employed by the Bank or ORIGIN on the Effective Date of a Change in Control (as defined herein) of the Bank or ORI GIN in the same position, or in a position having comparable duties and authority, as on the date of the execution of this Agreement and Executive’s employment must thereafter terminate as provided in such Section 4. If Executive’s employment with the Bank or ORIGIN is terminated (either directly or constructively) or Executive is transferred to a position that does not have comparable duties or authority or is required to move to a different office more than 30 miles away or requires an average commute of more than 45 minutes one way during the period commencing on the earlier of the date of commencement of negotiations leading to a Change in Control or six months prior to the Effective Date of the Change in Control, and if it is reasonably demonstrated by Executive that such termination of employment or transfer of position (i) was at the request of a third party who has taken steps reasonably calculated to effect a Change in Control or (ii) otherwise arose in connection with or in anticipation of a Change in Control, then for all purposes of this Agreement, Executive shall be deemed to be employed on the Effective Date of such Change in Control in the same or a comparable position.

This Agreement shall be effective and binding as of the date of its execution for an initial three (3) year period. Thereafter, this Agreement will automatically renew on the anniversary date of the Agreement for successive one-year terms unless not later than ninety (90) days preceding the upcoming renewal date, either party shall notify the other, in writing, of the termination of this Agreement at the end of the current term. Notwithstanding the preceding, this Agreement shall earlier terminate, automatically, upon Executive’s Termination of Service (as defined in Section 7(e) below) prior to the end of the Term of this Agreement or any renewal thereof. In such event, all obligations of the parties under this Agreement shall terminate except as otherwise specifically provided herein.

For purposes of this Agreement, a “Change in Control” shall be defined as the occurrence, through sale, exchange, merger, redemption or otherwise, of:

(i)    The acquisition by any one person, or by more than one person acting as a group, of ownership of stock that, together with stock held by such person or group, constitutes more than fifty percent (50%) of the total fair market value or total voting power of the stock of the Bank or ORIGIN;

(ii)    The acquisition by any one person, or by more than one person acting as a group, during the twelve-month period ending on the date of the most recent acquisition, of ownership of stock possessing fifty percent (50%) or more of the total voting power of the stock of the Bank or ORIGIN;

(iii)    The replacement during any twelve-month period of a majority of the members of the Board of the Bank or ORIGIN by directors whose appointment or election is not endorsed by a majority of the members of such Board before the date of such appointment or election; or

(iv)    The acquisition by any one person, or more than one person acting as a group, during the twelve-month period ending on the date of the most recent acquisition, of assets of the Bank or ORIGIN having a total gross fair market value of more than fifty percent (50%) of the total gross fair market value of all of the assets of the Bank or ORIGIN immediately prior to such acquisition or acquisitions.

For purposes of the above, “persons acting as a group” shall have the meaning as in Treasury Regulations Section l.409A-3(i)(5)(v)(B).

It is intended that the definition of Change in Control contained herein shall be the same as a change of ownership of a corporation, a change in the effective control of a corporation and/or a change in the ownership of a substantial portion of a corporation’s assets as reflected in Treasury Regulations Section l.409A-3(i)(5), as modified by the substitution of the higher percentage requirement in items (ii) and (iv) above; and all questions or determinations in connection with any such Change in Control shall be construed and interpreted in accordance with the provisions of such Regulations. This definition of Change in Control shall be applicable only for purposes of determining Executive’s rights under this Agreement which become applicable in the event of such a Change in Control and for no other purpose.

(a)    In the event Executive’s service with the Bank and/or ORIGIN is involuntarily terminated for any reason other than Cause (as defined in Section 7(a)) or if Executive resigns Executive’s position for Good Reason (as defined in Section 7(d)) within the two-year period beginning on the Effective Date of a Change in Control of the Bank and/or ORIGIN, the Bank and/or ORIGIN will pay to Executive and Executive will receive a severance benefit equal to two (2) times Executive’s then-current annual base salary and in addition to receive a payment equal to two (2) time the average of the incentive bonus paid within the three (3) calendar years (or such fewer years as Executive has been employed by the Employer) immediately preceding the date of the Executive’s termination. Notwithstanding the preceding, no such benefit shall become payable to Executive and neither the Bank or ORIGIN shall have any obligation for the payment of such benefit to Executive if in connection with such termination or resignation Executive remains employed, or is simultaneously reemployed, by ORIGIN or any affiliate thereof in a position having comparable duties, authority and compensation as Executive’s position with the Bank or ORIGIN immediately preceding such Change in Control.

(b)    The severance benefit to which Executive shall become entitled under Subsection (a) above, if any, shall be paid in a single lump-sum payment. Such lump­ sum payment shall be made within the thirty (30) day period beginning on the later of Executive’s Termination of Service or the Effective Date of the Change in Control. In no event shall any payment be made under this Section 4 until Executive incurs a Termination of Service.

(c)    Notwithstanding the preceding and to the extent required by Section 409A of the Code, if any amount constituting non-exempt deferred compensation under Section 409A of the Code is or becomes payable to Executive at a time in which Executive is a “specified employee” as defined in Section 409A(a)(2)(B)(i) of the Code and Treasury Regulation § l.409A-1 (i), solely as a result of Executive’s Termination of Service, payment of such amount shall be delayed until the first business day after the six-month anniversary of the date of such Termination of

Service. Whether or not Executive is a specified employee and whether or not the payment is required to be delayed for such six­ month period shall be determined in accordance with the provisions of Treasury Regulation § l.409A-l (i).

(d)    Notwithstanding anything in this Section 4 to the contrary, the parties hereto acknowledge and agree that upon their mutual consent, they may modify or amend the provisions hereof or terminate this Agreement at any time before or after the Effective Date of a Change in Control and that, in the event of a termination, the provisions hereof shall thereafter have no further force or effect. No such modification, amendment or termination, however, shall be made which shall have the effect of causing any provision hereof or any payment hereunder to violate or result in immediate taxation to Executive under Section 409A of the Code and any such attempted modification, amendment or termination shall be void and of no effect.

(e)     In the event Employee undertakes legal action to enforce rights under this Section 4 and prevails in any such court action, Employer shall pay to Employee all costs and expenses, including, but not limited to, attorney’s fees and court costs incurred by Employee in connection with the enforcement of Employee’s rights under this Section 4.

Executive acknowledges and agrees that any and all non public information regarding the Bank, ORIGIN and customers thereof is confidential and the unauthorized disclosure of such information will result in irreparable harm to the Bank and/or ORIGIN. Executive shall not, during Executive’s employment by the Bank, ORIGIN or any affiliate thereof and until such time as such confidential information becomes generally available to the public through no fault of Executive or other person under a duty of confidentiality to the Bank, ORIGIN or any affiliate thereof, disclose or permit the disclosure of any such confidential information to any person other than an employee of the Bank, ORIGIN or an affiliate thereof, or to an individual engaged by the Bank, ORIGIN or an affiliate thereof to render professional services thereto under circumstances that require such person to maintain the confidentiality of such information, except as such disclosure may be required by law. The provisions of this Section 5 shall survive any termination of this Agreement. For purposes of this Section 5, the term “confidential information” shall not include information that (i) was or becomes generally available to the public other than as a result of disclosure by Executive, (ii) was or becomes available to Executive on a non-confidential basis from a source other than the Bank or ORIGIN.

Executive agrees that during Executive’s employment by the Bank or a successor following a Change in Control and for a period of two (2) years thereafter (the “Restrictive Period”), Executive will not:

(i) Divert or attempt to divert from the Bank, ORIGIN or any affiliate thereof (or any successor) any business by influencing or attempting to influence or soliciting or attempting to solicit any customers of the Bank, ORIGIN or any affiliate (or any successor) or any particular customer with whom the Bank, ORIGIN or any affiliates thereof (or any successor) had business contacts in the one-year period immediately preceding Executive’s termination or with whom Executive may have dealt at any time during Executive’s employment by the Bank, ORIGIN or an affiliate thereof (or any successor). The provisions of this Subsection (i) shall apply in the parishes and counties listed in the Exhibit “A” attached hereto and made a part hereof, as the same may be amended from time to time. The parties agree that Exhibit A may be amended from time to time by the Bank, which amendments shall be presented to Executive in writing and shall be deemed accepted by Executive if Executive remains employed by Bank on the third (3’d) business day following receipt of any such amendment.

(ii) Recruit, solicit, hire, attempt to hire, or assist any other person to hire any employee of the Bank, ORIGIN or any affiliates thereof (or any successor) or any person who was an employee of any of the foregoing in the six (6) months immediately preceding Executive’s termination of employment, or solicit or encourage any employee of any of the foregoing to terminate employment.

(iii) Assist any person in any way to do, or attempt to do, anything prohibited by the foregoing.

The provisions of this Section 6 shall survive any termination of this Agreement.

For purposes of this Agreement, the following terms shall have the meanings given them in this Section 7.

(a)    “Cause” shall mean

(i)    The willful continued failure by Executive to substantially perform Executive’s duties after a demand for substantial performance is delivered to Executive that specifically identifies the manner in which the Bank and ORIGIN believe that Executive has not substantially performed Executive’s duties, and Executive has failed to resume substantial performance of Executive’s duties on a continuous basis within fourteen (14) days of receiving such demand;

(ii)    The willful engaging by Executive in conduct which is demonstrably and materially injurious to the Bank, ORIGIN, and/or any affiliate thereof, monetarily or otherwise; or

(iii)    Executive’s conviction of a felony or conviction of a misdemeanor which materially impairs Executive’s ability substantially to perform Executive’s duties.

For purposes of this definition, no act, or failure to act, on Executive’s part shall be deemed “willful” unless done, or omitted to be done, by Executive not in good faith and without reasonable belief that Executive’s action or omission was in the best interest of the Bank, ORIGIN and/or any affiliate thereof.

(b)    “Code” shall mean the Internal Revenue Code of 1986, as amended.

(c)    “Effective Date of a Change in Control” shall mean the date on which the event or events constituting a Change in Control is consummated.

(d)    “Good Reason” shall mean any of the following occurring without Executive’s consent:

(i)    a material diminution in Executive’s position, authority, duties or responsibilities from those which Executive held immediately prior to the Effective Date of the Change in Control;

(ii)    a material diminution in the authority, duties, or responsibilities or Executive’s supervisor after the effective date of the Change in Control;

(iii)    requiring Executive to be based at any office which is a material change from the geographic location of the office at which Executive was employed immediately prior to the Change in Control; provided, however, that any such relocation request shall not be considered a material change if such relocation is within a twenty-mile radius of the office at which Executive was based immediately prior to the Effective Date of a Change in Control;

(iv)    a material diminution in the budget over which Executive retains authority;

(v)    a material diminution in Executive’s annual base salary; or

(vi)     any other action or inaction that constitutes a material breach by the Bank or ORIGIN of any agreement, including this Agreement, pursuant to which Executive performs services for the Bank or ORIGIN.

Notwithstanding the preceding, however, none of such actions shall constitute “Good Reason” unless (1) Executive provided the Bank and/or ORIGIN notice of the existence of such condition within ninety (90) days of the initial existence thereof specifically identifying the acts or omissions constituting the grounds for Good Reason and a

period of at least thirty (30) days following such notice within which to remedy such condition and (2) Executive’s termination occurs within the eighteen (18) month period following the initial existence of such condition.

(e) “Termination of Service” means the termination of Executive’s employment with the Bank, ORIGIN and all affiliates thereof for any reason, and which termination of service constitutes a “separation from service” determined in accordance with the provisions of Section 409A of the Code and the Treasury Regulations thereunder.

The parties recognize that the enforceability of compensation agreements with banks are subject to some uncertainty and that banks and their bank holding companies are subject to regulatory restrictions that change from time to time. As a result, Executive may be prevented from obtaining or enforcing any or all of Executive’s rights hereunder. If the payment required to be made hereunder cannot be made because of such regulatory restrictions or other prohibitions of law, lawful regulations or binding order of a court, tribunal, or regulatory agency, then, (i) if and to the extent the prohibitions are applicable to the Bank, and not ORIGIN, ORIGIN shall make the required payments; (ii) if and to the extent the prohibitions are applicable to ORIGIN and not the Bank, the Bank shall make the required payments; and (iii) if the prohibitions apply to both ORIGIN and the Bank, the maximum amount possible of required payments not prohibited shall be made by the Bank and/or ORIGIN. Nothing herein shall require the Bank or ORIGIN to perform any obligation hereunder if such performance is prohibited or limited by applicable law or regulation, as determined in a proceeding or adjudication by a court, tribunal, or regulatory agency having authority to so determine, which determination is final and subject to no further appeals. The parties further acknowledge and agree that it is the intent of this Agreement that it be enforced to the fullest degree permitted by law and regulation.

All notices and other communications provided for by this Agreement shall be in writing and shall be deemed to have been duly given when delivered in person or mailed by United States Certified Mail, return receipt requested, postage prepaid, addressed as follows:

or to such other addresses any party may have furnished to the other in writing in accordance with this Agreement.

Notwithstanding any other prov1s1on in this Agreement, the Bank, ORIGIN and Executive intend for this Agreement to comply in all respects with the provisions of Section 409A of the Code and Treasury Regulations and other guidance issued thereunder. Each provision and term of this Agreement should be interpreted accordingly. If any provision or term of this Agreement would be prohibited by or be inconsistent with Section 409A of the Code, then such provision shall be deemed to be conformed to comply with Section 409A of the Code or, if it is not possible to conform the provision to comply with Section 409A, such provision shall be null and void to the extent, and only to the extent, required for this Agreement to be in compliance with Section 409A of the Code without affecting the remainder of this Agreement.

The Bank, ORIGIN and Executive acknowledge and agree that Executive’s employment by the Bank or ORIGIN is at will and that Executive may resign from employment with the Bank and/or ORIGIN at any time, whether before or after the occurrence of a Change in Control. Executive further acknowledges and agrees that Executive’s employment is at the pleasure of the Board of Directors of the Bank and/or ORIGIN and that Executive may be removed at any time by such Board of Directors.

The provisions of this Agreement shall be interpreted and construed in accordance with, and enforcement may be made under, the laws of the State of Louisiana.

(a)    The Agreement is personal to Executive and, without the prior written consent of the Bank and ORIGIN, shall not be assignable by Executive. This Agreement shall inure to the benefit of and be enforceable by Executive’s legal representative.

(b)    This Agreement shall be binding upon and inure to the benefit of the Bank, ORIGIN and the successors and assigns thereof.

If any provision or portion of this Agreement shall be determined to be invalid or unenforceable for any reason, the remaining provisions of this Agreement shall be unaffected thereby and shall remain in full force and effect to the fullest extent permitted by applicable law.

This Agreement sets forth the entire Agreement of the parties hereto and supersedes all prior agreements, understandings and covenants with respect to the subject matter hereof. This Agreement may be amended or terminated only by mutual agreement of the parties in writing.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the day and year first above written.
