(b)    Subject to the terms of this Agreement, in consideration of Executive’s agreements contained herein, for the fiscal year beginning the Effective Date, Executive’s Base Salary shall be $990,000.00 per annum (“Base Salary”), which shall be payable in semi-monthly or other agreed-upon equal installments during the year and shall be subject to deductions for customary withholdings, including, without limitation, federal and state withholding taxes and social security taxes. Executive’s Base Salary in subsequent fiscal years will be subject to adjustment pursuant to Section 2.3(f).

2.4    Term.

(a)    General Term. This Agreement shall commence on the Effective Date and terminate on January 1, 2019.

(b)    Termination for Cause or Voluntary Termination. If the Executive is terminated by the Company for Cause or if the Executive voluntarily terminates his employment without Good Reason, the Executive shall be entitled only to his Base Salary through the date of termination, but shall not be entitled to any further Base Salary or any applicable bonus or benefits for that year or any future year, except as may be provided in an applicable benefit plan or program, or to any severance compensation of any kind, nature or amount.

(c)    Termination Without Cause or for Good Reason.

(i)    If the Executive is involuntarily terminated by the Company without Cause or terminates his employment for Good Reason, the Executive shall be entitled to all previously earned and accrued but unpaid Base Salary up to the date of such termination. Provided the Executive has executed a release of claims in a form satisfactory to the Company within 21 days after his involuntary termination of employment without Cause or termination for Good Reason, the Executive shall also be entitled to severance pay equal to 2.99 times his annual Base Salary. Such severance payments will be made in equal installments over a 36 month period payable on the dates on which the Executive’s Base Salary would have otherwise been paid if Executive’s employment had continued with the first payment being made on the first payroll date occurring after the above described 21 day period. All payments shall be subject to deductions for customary withholdings, including, without limitation, federal and state withholding taxes and social security taxes. If the Executive dies during the severance period, any remaining severance payments shall be paid to his surviving spouse, or if there is no surviving spouse, to his estate. Notwithstanding anything herein to the contrary, the Executive shall not be entitled to such severance pay hereunder if he becomes entitled to any termination payments or other severance payments under the Change of Control Agreement.

(ii)    In the event that the Executive is determined to be a specified employee in accordance with Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”), and the regulations and other guidance issued thereunder for purposes of any severance pay payment under this subsection (c), such severance payments shall begin on the first payroll date that is more than six months following the date of separation from service, but only to the extent that such payments do not satisfy either the short term deferral exception to Code Section 409A described in 26 CFR §1.409A-1(b)(4) (“Short Term Deferral Exception”) or, to the extent such payments do not satisfy the Short Term Deferral Exception, the involuntary termination exception to Code Section 409A described in 26 CFR §1.409A-1(b)(9). At all times, the right to all such installment payments made under this subsection (c) shall be treated as the right to a series of separate payments within the meaning of 26 CFR §1.409A-2(b)(2)(iii). In the event that a termination of employment occurs on or after December 1st of a calendar year that would entitle the Executive to severance under Section 2.4(c) above, and severance payments are payable prior to the first payroll date that is more than six months following the date of separation from service, such severance benefits shall commence no earlier than the first payroll date in the following calendar year and within 90 days after such separation from service. Any amount that (i) is payable upon termination of Executive’s employment with the Company under any provision of this Agreement, and (ii) is subject to the requirements of Section 409A, shall not be paid unless and until the Executive has Separated from Service as defined in in Treasury Regulation Section 1.409A-1(h).

(d)Normal Retirement. If Executive voluntarily terminates his employment by reason of Normal Retirement, no severance payments shall be due and owing to Executive, but Executive shall be entitled to such benefits and payments as stipulated in the Company’s various compensation and benefit plans for retirees. In

addition, any agreement governing any equity or other long-term incentive award the service period or performance period of which extends beyond the date upon which Executive would be eligible for Normal Retirement shall provide for full vesting of such award upon Normal Retirement. Further, upon Normal Retirement, Executive will remain eligible to receive any Annual Bonus for the fiscal year in which such Normal Retirement occurs, pro-rated through the date of Normal Retirement, payable in accordance with and subject to the performance criteria set forth in the Annual Bonus Plan for such year.

(e)No Mitigation. To the extent that Executive shall receive compensation for personal services from employment other than with the Company subsequent to a termination of Executive’s employment with the Company, the amounts so earned shall not be offset against the amounts (if any) due under this Agreement following Executive’s termination of employment.

(f)Severance Forfeiture. Executive agrees that the Executive shall be entitled to the severance pay as set forth in this Section 2.4 only if the Executive has not materially breached as of the date of termination any provisions of this Agreement or of any other agreement with the Company and does not materially breach such provisions at any time during the period for which such payments are to be made. The Company’s obligation to make such payments will terminate upon the occurrence of any such material breach during the severance period.

(g)No Additional Severance. Executive hereby agrees that no severance compensation of any kind, nature or amount shall be payable to Executive, except as expressly set forth in this Section 2.4 or in the Change of Control Agreement, as applicable, and Executive hereby irrevocably waives any claim for any other severance compensation. Notwithstanding anything herein to the contrary, Executive shall not be entitled to any severance payment under this Agreement if he becomes entitled to any termination payments or other severance payments under the Change of Control Agreement.

(h)Death or Disability. The Company’s obligation under this Agreement terminates on the last day of the month in which the Executive’s death occurs or on the date as of which Executive first becomes entitled to receive disability benefits under the Company’s long-term disability plan. The Company shall pay to Executive or the Executive’s estate all previously earned and accrued but unpaid Base Salary up to such date. Executive (or his estate) shall also be paid a pro rata Annual Bonus for the year of termination based on actual performance for that fiscal year. Thereafter, the Executive or his estate shall not be entitled to any further Base Salary, bonus or benefits for that year or any subsequent year, except as may be provided in an applicable benefit plan or program.

2.5    Confidential Information.

(a)    Executive recognizes that the Company is engaged in the business of research, development, manufacture and sale of chemicals, chemical products and allied activities throughout the world (the “Company’s Business”), which business requires for its successful operation the fullest security of its Confidential Information of which Executive will acquire knowledge during the course of his employment.

(b)    Executive shall use his best efforts and diligence both during and after his employment with the Company, regardless of how, when or why Executive’s employment ends, to protect the confidential, trade secret and/or proprietary character of all Confidential Information.
