THIS EMPLOYMENT AGREEMENT (“Agreement”), dated as of the 1st day of September, 2015 (the “Effective Date”), is entered into by and between LSB Industries, Inc., Oklahoma City, Oklahoma (the “Company”) and Daniel D. Greenwell (“Executive”).

IN CONSIDERATION of the premises and the mutual covenants set forth below, the parties hereby agree as follows:

1. Employment. The Company hereby agrees to employ Executive as the Interim Chief Executive Officer of the Company, and Executive hereby accepts employment, on the terms and conditions set forth in this Agreement. During the Term, Executive will serve as Interim Chief Executive Officer of the Company and will report directly to the Board of Directors of the Company (the “Board”) and shall perform all services reasonably required to fully execute the duties and responsibilities associated with such position. In addition, Executive shall continue to serve as a member of the Board and termination of Executive’s employment shall not effect Executive’s status as a Board member.

2. Term. Executive or Company may terminate Executive’s employment under this Agreement at any time upon thirty (30) days written notice. The Company may terminate Executive’s employment for Cause without notice. For purposes of this Agreement “Cause” shall mean termination of employment for one of the following reasons: (i) Executive’s conviction of or plea of no contest to a felony or other crime involving fraud, dishonesty or moral turpitude; (ii) Executive’s commission of a willful wrongful act intending to enrich himself at the expense of the Company, or that causes serious injury, monetary or otherwise, to the Company; (iii) Executive’s willful or reckless neglect or misconduct in the performance of his duties which results in a material adverse effect on the Company; (iv) Executive’s material violation or disregard of a Company policy; or (v) Executive’s habitual or gross neglect of duties. Provided that, an act, or failure to act, shall not constitute Cause if it can reasonably be cured by Executive within 10 business days after Executive is given written notice by the Board. The determination of whether it can reasonably be cured shall be determined by the Board. The “Term” shall mean the period from September 1, 2015 through the date Executive’s employment terminates.

If Executive is unable to participate in the Company’s health plan on the Effective Date, the Company will reimburse him monthly for the difference in the cost of the premiums paid for coverage for himself and his family and the cost that he would have otherwise incurred had he been eligible to participate in the Company’s health plan until such time as he is able to participate in the Company’s health plan.

(b) the Company will reimburse Executive, pursuant to the Company’s policy, for reasonable business expenses incurred, but not paid, prior to the date of termination, unless such termination resulted from a misappropriation of Company funds, and the expenses which remain unreimbursed under Section 4, with such reimbursements made in the next payroll following the date of Executive’s termination of employment; and

(c) Executive will be entitled to any other rights, compensation and/or benefits as may be due to Executive following termination to which he is otherwise entitled in accordance with the terms and provisions of any plans or programs of the Company or any other agreement between Executive and the Company.
