Renwick, and (ii) Executive Vice President, Manufacturing, Scott D. Bemis (together, the “Executives” and each, an “Executive”). The Agreements provide for certain payments to the Executives if, during the Term (defined below) a Change in Control occurs and during the period beginning 180 days before and ending on the 12-month anniversary following the closing date that a Change in Control occurs (the “Change in Control Period”), the Executive’s employment is terminated by the Company without “Cause” or by the Executive for “Good Reason” (each term as defined in the Agreements) (each, a “Qualifying Termination”). For purposes of the Agreements, the term “Change of Control” has the same meaning as set forth in the LSB Industries, Inc. 2025 Long-Term Incentive Plan, as amended, provided that no transaction or series of transactions will be deemed to constitute a Change in Control unless and to the extent such transaction or transactions constitute a change in ownership or control under Section 409A of the Internal Revenue Code. Pursuant to the Agreements, upon such Qualifying Termination, each Executive will be entitled to receive: (A) with respect to Mr. Renwick, an amount equal to two times Mr. Renwick’s annual base salary at the rate in effect immediately prior to the date of the Qualifying Termination and (B) with respect to Mr. Bemis, an amount equal to one times Mr. Bemis’s annual base salary at the rate in effect immediately prior to the date of the Qualifying Termination, in each case provided that such Executive timely executes and delivers of a release of claims in favor of the Company. The term of the Agreements commences on January 14, 2026 and ends on January 15, 2027 (the “Initial Term”), and will automatically renew for successive 12-month periods (the Initial Term and all renewal periods, collectively, the “Term”) unless the Company provides the Executive with written notice of non-renewal at least 90 days prior to the expiration of the then-current Term. Notwithstanding the foregoing, if a Change in Control occurs during the Term, the Term will continue until the later of: (i) the first anniversary of the closing date of the Change in Control; (ii) the satisfaction of all obligations of the parties under the Agreements; or (iii) the date of termination of the Executive’s employment by the Company for Cause, by the Executive without Good Reason, or due to the Executive’s death or Total and Permanent Disability (as defined in the Agreements).
