ANNUAL LTI TARGET: You will be eligible to participate in the Company's LTI program (the "LTI Program"). Beginning in 2024, your annual target award opportunity under the LTI Program is expected to be S2,000,000 (on an annualized basis) (the "LTI Target").

SIGN-ON BONUS: Following the Start Date, the Company shall pay you a one-time sign-on bonus of $200,000, less applicable payroll deductions and withholdings ("Sign-On Bonus"), subject to incremental reduction, as described herein.

Except as required for the proper performance of Executive's regular duties for the Company or as expressly authorized in writing in advance by the Company, Executive will not copy any Documents or remove any Documents or copies or derivatives thereof from the premises of the Company Group. Executive will safeguard, and return to the Company immediately upon termination of Executive's service with the Company, and at such other times as may be specified by the Company, all Documents and other property of the Company Group and all documents, records and files of its customers, subcontractors, vendors and suppliers ("Third-Party Documents"), as well as all other property of such customers, subcontractors, vendors and suppliers then in Executive's possession or control.

provision of this Agreement to be unenforceable or invalid for any reason, Executive and the Company Group agree that the covenants shall be interpreted to extend only over the maximum period of time for which they may be enforceable, the maximum geographical area as to which they may be enforceable and to the maximum extent in any and all respects as to which they may be enforceable, all as determined by such court or tribunal. Executive acknowledges and agrees that in the event of a breach or threatened breach of any of the covenants and promises contained in this Agreement, the Company Group will suffer irreparable injury for which there is no adequate remedy at law and for which monetary damages alone shall not compensate the Company for its injury. The Company Group will therefore be entitled to: (a) preliminary and permanent injunctive relief in addition to any other legal or equitable remedies available to the Company, without the posting of a bond, enjoining Executive from engaging in activities in breach of this Agreement; (b) an equitable accounting of all profits or benefits arising out of such violation or breach; and (c) direct, incidental, and consequential damages to the Company arising from the violation or breach. These rights and remedies shall be cumulative and in addition to any and all other rights and remedies to which the Company may be entitled.

In addition, and notwithstanding the terms of Section 140), the Company Group will be entitled to avail itself of all other remedies as may now or hereafter exist in law or equity for breach by Executive of the covenants contained in this Agreement, and resort to any remedy available shall not preclude the concurrent or subsequent obtaining of other remedies, including monetary damages or forfeiture of compensation. Tn addition, in the event of a breach by Executive of any of the covenants and promises contained in this Agreement, Executive shall forfeit any right to compensation or other benefits that are not yet earned, including all post-termination compensation and benefits.

14.Miscellaneous.

a.Entire Agreement. With respect to the subject matter hereof, this Agreement supersedes all prior and contemporaneous communications, agreements and understandings, written or oral, regarding the same, and shall not be limited by any future agreements between the parties. Future long term incentive awards, containing restrictive covenants, shall be read together and have effect so far as practicable as though all restrictive covenant provisions thereof and hereof were contained in one instrument. If there is a conflict between this Agreement and a future long term incentive award, and in the absence of a written amendment to this Agreement signed by the Company and Employee, this Agreement shall prevail and control.

b.Severability. The provisions of this Agreement are severable, and no breach of any provision of this Agreement by the Company, or any other claimed breach of contract or violation of law, shall operate to excuse Executive's obligation to fulfill the requirements of this Agreement.

unenforceable in any respect, it shall not affect any other provisions, and shall be construed by limiting it so as to be enforceable to the maximum extent permissible by law.

f.Assignment. Neither the Company nor Executive may make any assignment of this Agreement or any interest in it, by operation of law or otherwise, without the prior written consent of the other; provided, however, the Company may assign its rights and obligations under this Agreement without Executive's consent (i) in the event that Executive is transferred to a position with another member of the Company Group or (ii) in the event that the Company shall hereafter effect a reorganization, consolidate with, or merge into any company or entity or transfer to any company or entity all or substantially all of the business, properties or assets of the Company or any division or line of business of the Company with which Executive is at any time associated.

If there is a dispute as to whether the Company or Executive is the prevailing party, the arbitrator will decide this issue.

vi.Time Limitation for Commencing Arbitration. The same statute of limitations that would have applied if the Claim was made in a judicial forum will apply to any Claim subject to arbitration.

vii.Damages and Other Relief. The arbitrator may award the full individual remedies that would be available if the Claim had been filed in court.

viii.Survival. This Section 14(j) survives the termination of this Agreement and Executive's service with the Company. For the avoidance of doubt, this Section l 4(j) supersedes all other agreements and drafts, oral or written, between the Company and Executive with respect to the subject matter of dispute resolution, including, without limitation, any provisions regarding dispute resolution in previously executed award agreements and arbitration agreements.

ix.Construction. Except as provided above, if any court of competent jurisdiction or arbitrator finds any part or provision of in this Section 14(j) unenforceable, such a finding will not affect the validity of the remainder of this Agreement, and all other parts and provisions remain in full force and effect.
