Any severance pay will be paid, at StandardAero’s discretion, either in approximately equivalent amounts over six months in accordance with StandardAero’s regular payroll practices (commencing with the first regular payroll date after the effective date of the release agreement), or in a lump sum within 30 days of the effective date of the release.

For purposes of this supplement to your offer letter, “Cause” shall mean: (1) Executive’s indictment for any felony or indictment for any other criminal offense, other than a misdemeanor traffic offense; (2) Executive’s engagement in any act involving gross misconduct, dishonesty, or disloyalty that is materially injurious to Company or any of its affiliates; (3) Executive’s willful and continued breach of, or failure substantially to perform under or comply with, any of the material terms and covenants of Executive’s employment agreement, offer letter or restrictive covenant agreement with the Company or any of its affiliates; (4) Executive’s willful and continued breach of, or refusal or failure substantially to perform under, any policy or reasonable performance goals set by the Company or its affiliates with respect to Executive’s job duties or responsibilities, the operation of Company’s or its affiliate’s business and affairs, or the management of Company’s or its affiliate’s employees; and (5) Executive commits or has committed (or is reasonably believed by the Company to have committed) a breach of any laws or regulations which may affect or relate to the conduct of the Company’s or its affiliate’s business; provided, however, that with respect to (3) and (4) above, Executive will be provided notice of any misconduct and/or breach constituting Cause and given reasonable opportunity (not to exceed 30 days) to cure the misconduct and/or breach (unless such misconduct and/or breach is determined by the Company not to be susceptible to cure, in which case termination shall be deemed to be immediate), and provided further that such thirty (30) day cure period shall only be available for the first such misconduct and/or breach of the same or substantially similar type and subsequent misconduct and/or breach of the same or substantially similar type shall constitute Cause without regard to Executive’s subsequent cure of same.

It is expressly agreed by you and the company that the forgoing provision concerning severance pay is supplemental to the original offer letter, which is by reference made a part hereof, and all the terms, conditions, and provisions thereof, unless specifically amended herein, are to apply to your employment as though they were expressly written, incorporated, and included herein.
