The Gross-Up Payment shall be in an amount such that, after payment by you of all taxes (including any interest or penalties imposed with respect to such taxes), including any Excise Tax imposed upon the Gross-Up Payment, you retain an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payment. To address compliance with Section 409A of the Code, the Company and you agree that the Gross-Up Payment by the Company described under this Paragraph (g)(ii) will in no event be made later than the end of the calendar year in which you remit those amounts to the taxing authority.

(o)    The Company shall deliver to you on the Resignation Date the release set forth on Exhibit B attached hereto (the “Company Release”), which Company Release shall only become effective upon the irrevocability of the Executive Release provided for in Section 2(h) hereof.

McMullen as Chairman, Chief Executive Officer and President of the Company, and from the Board, each to be effective December 1, 2016. The Board accepted Mr. McMullen’s resignation pursuant to an agreement between he and the Company.

Under the agreement, Mr. McMullen’s departure will generally be considered an involuntary separation consistent with the terms of his Amended and Restated Employment Agreement dated December 1, 2008 (the “Employment Agreement”), except for certain benefit plans where Mr. McMullen meets the qualifications for “retirement.” Mr. McMullen will receive a severance payment as specified in the Employment Agreement equal to two times the sum of (i) his annual base salary and (ii) his highest annual bonus in the last three fiscal years (but not less than 100% of his base salary). Mr. McMullen will also receive any accrued but unpaid vacation through his resignation date, his accrued annual bonus for fiscal year 2016, his earned and accrued performance shares for the 2015-2016 measurement period, and a prorated value for his performance shares for the 2016-2017 measurement period. The vesting of Mr. McMullen’s outstanding Company restricted shares will also be accelerated to December 1, 2016. Mr. McMullen will be entitled to executive level outplacement services (up to $25,000), continued health and life insurance benefits for up to 24 months, accrued vested benefits under the Company’s other benefit plans, programs, and arrangements, and a payment of $200,000 in respect of other foregone compensation and Mr. McMullen’s covenants under the agreement. In total, the Company anticipates Mr. McMullen will receive approximately $3.4 million in severance, and approximately $5-6 million in respect of accrued retirement benefits, accrued incentive payments, and other health and welfare benefits.

On November 7, 2016, the Board announced that Ms. Anne P. Noonan, 53, will become President and Chief Executive Officer of the Company, effective December 1, 2016. In this role, Ms. Noonan will be the Company’s principal executive officer. The Board has also announced that Ms. Noonan will be elected as a Class I member of the Board, effective December 1, 2016, to fill the vacancy created by Mr. McMullen’s resignation. Ms. Noonan’s term as a member of the Board will expire at the 2018 annual meeting of shareholders. Ms. Noonan will not be named to any standing committees of the Board, or receive any compensation for her service on the Board, due to her status as an executive officer of the Company.

Ms. Noonan, currently the president of OMNOVA’s Performance Chemicals business, brings nearly 30 years of experience in the chemicals industry. Prior to joining OMNOVA in 2014, Ms. Noonan served as Senior Vice President and President, Industrial Engineered Products for Chemtura Corporation, a global chemicals manufacturing company. During her 27 years with Chemtura and its predecessor, Great Lakes Chemical Corporation, Ms. Noonan held various roles in mergers & acquisitions, strategic business development, senior management, marketing, and sales. Ms. Noonan began her career as an Analytical Research Chemist with McNeil Specialty Chemicals Company and Squibb-Linson, Co. in 1985. She earned her M.S. in organometallic chemistry and her B.S. Honors degree in chemistry from University College Dublin, Ireland. Since 2015, Ms. Noonan has also served as a member of the Board of Directors of CF Industries Inc. (NYSE: CF), and a member of the Board of Directors for the American Chemistry Council.

Ms. Noonan has extensive knowledge and experience in operational and management issues relevant to the chemicals industry and has subject matter expertise in the areas of marketing, production, research & development, mergers & acquisitions, and strategic business development.

The election of Ms. Noonan as President and Chief Executive Officer is not being made pursuant to any arrangement or understanding between Ms. Noonan and any other person. There are no family relationships existing between Ms. Noonan and any executive officer or director of the Company. There are no transactions between the Company and Ms. Noonan that would be required to be reported pursuant to Item 404(a) of Regulations S-K, and no such transactions are currently contemplated.

Also on November 7, 2016, the Board announced its intention to separate the roles of Chairman and Chief Executive Officer, and to appoint William R. Seelbach, 68, a non-executive member of the Board since 2002, as its independent, non-executive Chairman, all effective on December 1, 2016. Mr. Seelbach is a Senior Advisor with the Riverside Company, the world's largest private equity firm focused on investing in companies at the smaller end of the middle market, and a Senior Managing Director of Headwaters SC, a consulting firm for privately owned businesses. In consideration of the additional time and effort that Mr. Seelbach will be required to spend in the role of Chairman, the Board has determined that in addition to the standard compensation provided to all directors, Mr. Seelbach will receive an annual retainer of $70,000 for his service as Chairman.

As the role of Chairman will be held by a non-executive director, Michael J. Merriman will also resign as the Board’s independent Presiding Director effective December 1, 2016. Mr. Merriman will remain a member of the Board and Chair of the Board’s Compensation and Corporate Governance Committee.
