Participation in the Myers Industries, Inc. Senior Officer Severance Plan (the “Severance Plan”), and to the extent that any modifications are made to the Severance Plan that would reduce your potential severance payments under Section 4.1(a) or Section 5.1(a)(1) of the Severance Plan as of the date hereof or materially reduce your other benefits thereunder or other facts arise that would cause you to cease to receive payments and benefits thereunder, you shall have this separate right to receive severance payments and benefits that are the same as the payments and benefits that would have been provided to you under the Severance Plan in its form as of the date hereof, subject to the same conditions to receipt of such severance benefits, including but not limited to a release of claims as described in Section 6 of the Severance Plan (disregarding any provisions that would enable the Company to reduce or eliminate participation in the Severance Plan or any payments or benefits thereunder), which include that if your employment is terminated by the Company other than for Cause or is terminated by you for Good Reason, but not in connection with a Change in Control, you will receive a severance payment of 1.5 times your Base Salary, and if such a termination occurs in connection with a Change in Control, you will receive a severance payment of 2.5 times the sum of your Base Salary and Target STIP. This Letter expressly survives participation in the Severance Plan.

Without duplication or reduction of payments or benefits that may be due to you under the Severance Plan or otherwise by this Letter, if your employment with the Company is terminated for any reason, then the Company shall pay you within 30 days of the date of such termination: (i) the Accrued Obligations (as defined under the Severance Plan), (ii) any compensation previously earned but deferred by you (together with any interest or earnings thereon) that has not yet been paid and that is not otherwise set to be paid at a later date pursuant to a deferred compensation arrangement subject to Section 409A of the

Internal Revenue Code and the rules and regulations thereunder (“Section 409A”); and (iii) any vested and accrued benefits through the date of termination.

For all purposes of this Letter and the Severance Plan as it is applicable to you, “Good Reason” shall mean the occurrence of one or more of the conditions set forth in Section 2.24 of the Severance Plan in its form as of the date hereof, or one or more of the following additional conditions, arising without your consent: (i) a requirement that you report other than to the Board; (ii) you ceasing to serve as the principal executive officer of the Company (for this purpose, “Company” is defined under the Severance Plan in its form as of the date hereof ), (iii) the failure of the Board to nominate and recommend you as a member of the Board, subject to shareholder vote; or (iv) a requirement that you relocate your primary residence or principal place of business more than 50 miles (other than your initial relocation to the Company’s headquarters). In order for a condition to constitute a Good Reason, you must follow the procedures set forth in Section 2.24 of the Severance Plan in its form as of the date hereof. For all purposes of this Letter and the Severance Plan as it is applicable to you, “Cause” and “Change in Control” shall have the meaning given to them in the Severance Plan in its form as of the date hereof.

For the avoidance of doubt, you shall not be entitled to duplicative payments or benefits under both this paragraph 11 and the Severance Plan.

You will be permitted to serve on the board of directors or managers of one publicly traded or privately held company, provided that such company does not directly compete with the Company and that you provide prior notice to the Board of such board service. You may also serve as a board member, consultant or advisor to not-for-profit entities (or any other entities with the consent of the Board) so long as such participation does not materially interfere with the performance of your duties, and you may manage your personal and family finances and investments.

Section 409A. Notwithstanding anything to the contrary contained in this Letter, the payments and benefits provided to you are intended to comply with or be exempt from Section 409A, and the provisions of this Letter shall be interpreted or construed consistently with that intent. Notwithstanding anything to the contrary contained in this Letter, (a) it is intended that the terms “termination” and “termination of employment” as used herein shall constitute a “separation from service” within the meaning of Section 409A, (b) each payment of compensation made to you shall be treated as a separate and distinct payment from all other such payments for purposes of Section 409A, (c) in no event may you be permitted to control the year in which any payment occurs, (d) if you are a “specified employee” (within the meaning of Treasury Regulation Section 1.409A-1(i)) on the date of your termination of employment, then any payment or benefit that would be considered “nonqualified deferred compensation” within the meaning of Section 409A that you are entitled to receive upon your termination of employment and that otherwise would be payable during the six-month period immediately following your termination of employment will instead be paid or made available

on the first day of the seventh month following your termination of employment (or, if earlier, the date of your death) and (e) with regard to any provision herein that provides for reimbursement of costs and expenses or in-kind benefits, except as permitted by Section 409A: (i) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit; (ii) the amount of expenses eligible for reimbursement, or in-kind benefits, provided during any taxable year shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year; and (iii) such payments shall be made on or before the last day of your taxable year following the taxable year in which the expense occurred, or such earlier date as required hereunder. In no event whatsoever will the Company or any of its affiliates be liable for any additional tax, interest or penalty that may be imposed on you by Section 409A or damages for failing to comply with Section 409A.

Miscellaneous. The provisions of this Letter shall survive the termination of your employment to the extent applicable, including, for the avoidance of doubt paragraph 11.
