On January 14, 2016, LSB Industries, Inc. (the “Company”) entered into a new employment agreement with Mark Behrman pursuant to which Mr. Behrman will continue to provide service to the Company as Executive Vice President of Finance and Chief Financial Officer (the “Employment Agreement”). The Employment Agreement has an effective date of December 31, 2015 and supersedes (except as noted in the Employment Agreement) the prior employment agreement between Mr. Behrman and the Company, which prior employment agreement was disclosed in the Company’s Current Report on Form 8-K filed on April 30, 2015.

Employment Agreement

The Employment Agreement provides that Mr. Behrman: (i) will serve as Executive Vice President of Finance and Chief Financial Officer of the Company for an initial term of three (3) years, with the Employment Agreement automatically renewing for successive one-year periods on the anniversary of the effective date until terminated by either party in accordance with the Employment Agreement; (ii) will receive an annual base salary of at least $500,000; (iii) will be eligible to receive a target annual cash performance bonus equal to 50% of Mr. Behrman’s base salary (the “target bonus”) and a maximum cash bonus equal to 100% of Mr. Behrman’s base salary, depending on the Company’s achievement of performance criteria, as determine by the Compensation Committee of the Board Directors of the Company; (iv) beginning in 2018 will receive an annual equity award of restricted stock that has a value of not less than 150% of Mr. Behrman’s base salary; and (v) will receive four (4) weeks of paid vacation per calendar year.

The Employment Agreement provides that Mr. Behrman will be eligible to receive benefits should his employment with the Company be terminated (i) due to death or disability, (ii) by the Company without Cause (as defined in the Employment Agreement), or (iii) by Mr. Behrman for Good Reason (as defined in the Employment Agreement). If Mr. Behrman’s employment with the Company is terminated due to death or disability, (1) Mr. Behrman will receive a lump sum payment equal to a pro rata portion of his annual bonus based on actual company performance for the year of termination, paid at the same time such bonuses are paid to all employees generally and (2) all outstanding equity awards will vest pro rata as of the date of termination. If Mr. Behrman’s employment is terminated by the Company without Cause or by Mr. Behrman for Good Reason, Mr. Behrman will receive (a) a lump sum payment equal to a pro rata portion of his annual bonus based on actual company performance for the year of termination, paid at the same time such bonuses are paid to all employees generally, (b) a lump sum payment equal to his base salary and target bonus (two (2) times base salary and target bonus should the termination occur within twenty-four (24) months following a Change in Control) payable on the first pay date following execution of a release of claims, (c) accelerated vesting of all outstanding equity awards as of the date of termination, and (d) continuation of health benefits for eighteen (18) months on the same economic terms applicable prior to his termination. All severance or termination benefits payable to Mr. Behrman under the Employment Agreement are dependent on his execution and delivery of a release of claims within sixty (60) days following the date of termination. Following termination of employment, Mr. Behrman will be subject to non-compete and non-solicitation restrictions for a period of twenty-four (24) months.
