This Current Report on Form 8-K/A of LSB Industries, Inc. (the “Company”) amends the Company’s Current Report on Form 8-K dated September 1, 2015 and filed with the Securities and Exchange Commission on September 4, 2015 (the “Original Filing”).

As disclosed in the Original Filing, the Company appointed current director Daniel D. Greenwell to serve as interim Chief Executive Officer. This Current Report on Form 8-K/A amends the Original Filing to set forth the description of the terms of the employment agreement entered into between Mr. Greenwell and the Company on October 26, 2015 and effective as of September 1, 2015 (the “Employment Agreement”).

The term of the Employment Agreement is from September 1, 2015 through the date the Employment Agreement is terminated. Mr. Greenwell or the Company may terminate the Employment Agreement at any time upon thirty (30) days written notice. The Employment Agreement may be terminated by the Company for cause without notice, in accordance with the terms of the Employment Agreement. Under the Employment Agreement, Mr. Greenwell receives a monthly base salary of $100,000 until December 31, 2015, and following December 31, 2015 such sum shall continue on a month to month basis until an alternative compensation program is established by the Company in its discretion. Mr. Greenwell will not be eligible to participate in the Company’s bonus program with respect to the 2015 calendar year and until such time as a new compensation program is established for Mr. Greenwell by the Company. The Employment Agreement also provides that Mr. Greenwell will be entitled to participate in all insurance and other employee benefit plans and program as generally are made available for the benefit of the Company’s employees. The Employment Agreement also provides that Mr. Greenwell will be reimbursed for certain expenses, including temporary housing expenses and a portion of the cost of premiums paid for health coverage if he is unable to participate in the Company’s health plan as of September 1, 2015. In addition, the Employment Agreement provides for certain benefits payments upon termination of Mr. Greenwell’s employment.

The foregoing does not constitute a complete summary of the terms of the Employment Agreement and reference is made to the complete form of the Employment Agreement that is attached as Exhibit 99.1.
