Exhibit 10.19

GENERAL RELEASE

I, Daniel D. Greenwell, in consideration of and subject to the performance by LSB Industries, Inc. (together with its affiliated companies and subsidiaries and its successors and assigns, the “Company”), of its obligations under Section 9 of the Employment Agreement, dated as of December 30, 2015 (the “Agreement”), do hereby release and forever discharge as of the date hereof the Company and its respective affiliates and subsidiaries and all present, former and future directors, officers, agents, representatives, employees, successors and assigns of the Company and/or its respective affiliates and subsidiaries and direct or indirect owners (collectively, the “Released Parties”) to the extent provided herein (this “General Release”). Terms used herein but not otherwise defined shall have the meanings given to them in the Agreement.

1.I understand that, other than the Accrued Benefits, the payments or benefits paid or granted to me under Section 9 of the Agreement represent, in part, consideration for signing this General Release and are not salary, wages or benefits to which I was already entitled. I understand and agree that I will not receive the payments and benefits specified in Section 9 of the Agreement, other than the Accrued Benefits, unless I execute this General Release and do not revoke this General Release within the time period permitted hereafter. Such payments and benefits will not be considered compensation for purposes of any employee benefit plan, program, policy or arrangement maintained or hereafter established by the Company or its affiliates.

2.Except as provided in paragraph 4 below and except for the provisions of the Agreement which expressly survive the termination of my employment with the Company, I knowingly and voluntarily (for myself, my heirs, executors, administrators and assigns) release and forever discharge the Company and the other Released Parties from any and all claims, suits, controversies, actions, causes of action, cross-claims, counter-claims, demands, debts, compensatory damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs and attorneys’ fees, or liabilities of any nature whatsoever in law and in equity, both past and present (through the date that this General Release becomes effective and enforceable) and whether known or unknown, suspected, or claimed against the Company and/or any of the Released Parties which I, my spouse, or any of my heirs, executors, administrators or assigns, ever had, now have, or hereafter may have, by reason of any matter, cause, or thing whatsoever, from the beginning of my initial dealings with the Company to the date of this General Release, and particularly, but without limitation of the foregoing general terms, any claims arising from or relating in any way to my employment relationship with Company, the terms and conditions of that employment relationship, and the termination of that employment relationship (including, but not limited to, any allegation, claim or violation, arising under: Title VII of the Civil Rights Act of 1964, as amended; the Civil Rights Act of 1991; the Age Discrimination in Employment Act of 1967, as amended (including the Older Workers Benefit Protection Act), the Equal Pay Act of 1963, as amended; the Americans with Disabilities Act of 1990; the Family and Medical Leave Act of 1993; the Worker Adjustment Retraining and Notification Act; the Employee Retirement Income Security Act of 1974; any applicable Executive Order Programs; the Fair Labor Standards Act; or their state or local counterparts; or under any other federal, state or local civil or human rights law, or under any other local, state, or federal law, regulation or ordinance; or under any public policy, contract or tort, or under common law; or arising under any policies, practices or procedures of the Company; or any

claim for wrongful discharge, breach of contract, infliction of emotional distress, defamation, or any claim for costs, fees, or other expenses, including attorneys’ fees incurred in these matters) (all of the foregoing collectively referred to herein as the “Claims”). I understand and intend that this General Release constitutes a general release of all claims and that no reference herein to a specific form of claim, statute or type of relief is intended to limit the scope of this General Release.

3.I represent that I have made no assignment or transfer of any right, claim, demand, cause of action, or other matter covered by paragraph 2 above.

4.I agree that this General Release does not waive or release any rights or claims that I may have under the Age Discrimination in Employment Act of 1967 which arise after the date I execute this General Release. I acknowledge and agree that my separation from employment with the Company in compliance with the terms of the Agreement shall not serve as the basis for any claim or action (including, without limitation, any claim under the Age Discrimination in Employment Act of 1967).  Notwithstanding anything herein to the contrary, I am not waiving any of the following (and definition of “Claims” shall not include these claims or rights):  (i) any claim or right to enforce the Agreement or this General Release; (ii) any claims which arise after the date of this General Release; (iii) my rights as a shareholder of the Company; and (iv) my rights to be indemnified and/or advanced expenses, including pursuant to the Company’s corporate governance documents or the Indemnification Agreements (as defined in the Agreement) or, if greater, applicable law and my rights to be covered under any applicable directors’ and officers’ insurance liability policies.

5.I agree that I hereby waive all rights to sue or obtain equitable, remedial or punitive relief from any or all Released Parties of any kind whatsoever with respect to claims released by me herein, including, without limitation, reinstatement, back pay, front pay, and any form of injunctive relief. Notwithstanding the foregoing, I acknowledge that I am not waiving and am not being required to waive any right that cannot be waived under law, including the right to file an administrative charge or participate in an administrative investigation or proceeding; provided, however, that I disclaim and waive any right to share or participate in any monetary award resulting from the prosecution of such charge or investigation or proceeding.

6.In signing this General Release, I acknowledge and intend that it shall be effective as a bar to each and every one of the Claims hereinabove mentioned or implied. I expressly consent that this General Release shall be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected Claims (notwithstanding any state or local statute that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating to any other Claims hereinabove mentioned or implied. I acknowledge and agree that this waiver is an essential and material term of this General Release and that without such waiver the Company would not have agreed to the terms of the Agreement. I further agree that in the event that I should bring a Claim seeking damages against the Company, or in the event that I should seek to recover against the Company in any Claim brought by a governmental agency on my behalf, this General Release shall serve as a complete defense to such Claims to the maximum extent permitted by law. I further agree that I am not aware of any pending Claim, or of any facts that could give rise to a Claim, of the type described in paragraph 2 as of the execution of this General Release.

7.I agree that neither this General Release, nor the furnishing of the consideration for this General Release, shall be deemed or construed at any time to be an admission by the Company, any Released Party or myself of any improper or unlawful conduct.

8.I agree that I will forfeit all amounts payable by the Company pursuant to the Agreement if I challenge the validity of this General Release. I also agree that if I violate this General Release by suing the Company or the other Released Parties with respect to Claims released by me herein, I will pay all costs and expenses of defending against the suit incurred by the Released Parties, including reasonable attorneys’ fees, and return all payments received by me pursuant to the Agreement on or after the termination of my employment. I further agree that if I materially violate any of my post-employment obligations under Sections 6 or 7 of the Agreement, I will also forfeit any cash severance amounts payable by the Company pursuant to either Section 10(d) or Section 10(e) of the Agreement, as applicable, other than the Accrued Benefits, and will return any such sums already paid, on an after-tax basis, to the Company; provided that no such payments shall be subject to forfeiture and/or repayment unless the Company has provided me with written notice of the events giving rise to such forfeiture and/or repayment and I have not ceased to engage in such activities within fifteen (15) days of my receipt of such written notice.

9.I agree that this General Release is confidential and agree not to disclose any information regarding the terms of this General Release, except to my immediate family and any tax, legal or other counsel that I have consulted regarding the meaning or effect hereof (and I will instruct each of the foregoing not to disclose the same to anyone) or as required by law or to the extent reasonably necessary in connection with any dispute between me and the Company regarding this General Release.

10.Any non-disclosure provision in this General Release does not prohibit or restrict me (or my attorney) from responding to any inquiry about this General Release or its underlying facts and circumstances by the Securities and Exchange Commission (SEC), the Financial Industry Regulatory Authority (FINRA), or any other self-regulatory organization or governmental entity.

11.I hereby acknowledge that Sections 6, 7, 8, 10, 11, 12, 13, 15, 16, 17, 19, 20, 21, 23, 24 and 25 of the Agreement shall survive my execution of this General Release. (need to make sure these match up pursuant to new numbering).

12.I represent that I am not aware of any Claim by me, and I acknowledge that I may hereafter discover Claims or facts in addition to or different than those which I now know or believe to exist with respect to the subject matter of the release set forth in paragraph 2 above and which, if known or suspected at the time of entering into this General Release, may have materially affected this General Release and my decision to enter into it.

13.Notwithstanding anything in this General Release to the contrary, this General Release shall not relinquish, diminish, or in any way affect any rights or claims arising out of any breach by the Company or by any Released Party of the Agreement after the date hereof.

14.Whenever possible, each provision of this General Release shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this General Release is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not

affect any other provision or any other jurisdiction, but this General Release shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. This General Release constitutes the complete and entire agreement and understanding among the parties, and supersedes any and all prior or contemporaneous agreements, commitments, understandings or arrangements, whether written or oral, between or among any of the parties, in each case concerning the subject matter hereof.

BY SIGNING THIS GENERAL RELEASE, I REPRESENT AND AGREE THAT:
