Termination of Employment. Employee’s employment with Jacobs terminated effective April 15, 2024 (“Separation Date”). After the Separation Date, except as in relation to the Legal and Other Assistance paragraph, Employee shall perform no further duties, functions or services for Jacobs.

Payment of Amounts Owed Employee. Employee acknowledges that Jacobs will pay all remuneration owed to Employee as a result of Employee’s employment with Jacobs through the Separation Date. Any outstanding expense reports for expenses incurred by Employee in the course of Employee’s employment with Jacobs through the Separation Date will be paid to Employee in accordance with normal approval and payment procedures.

Payment of Amounts Owed to Jacobs: Employee acknowledges and agrees that if any amounts are determined to be due or owing from Employee to Jacobs for any reason (e.g., personal expenses on Employee’s corporate credit card, etc.), whether determined at the time of or after Employee’s separation of employment, Employee will remain obligated to pay such amounts to Jacobs within 30 days after demand made by Jacobs, if such amounts have not already been deducted from the Lump Sum Payment paragraph amount (which Employee authorizes Jacobs to do at Jacobs’s sole discretion). As of the Effective Date (as defined below) of this Agreement, Jacobs is not presently aware of any amounts owed to Jacobs by Employee.

Lump Sum Payment. As consideration for Employee entering into this Agreement, Employee shall receive a lump sum payment of One Million Five Hundred Fifty Seven Thousand Five Hundred Eighty Six Dollars and Zero Cents ($1,557,586.00), less statutorily required deductions and withholdings, which lump sum payment is comprised of the following:

a cash payment equal to the result of multiplying Employee’s applicable Severance Multiple (as per Exhibit A to the Executive Severance Plan, Table 2) by the sum of Employee’s Base Salary ($765,000.00) and Employee’s target annual incentive award (100% of Base Salary, $765,000.00) (as per Executive Severance Plan, Section 3(a)(i));

a cash payment equal to the result of multiplying Employee’s applicable Severance Multiple (as per Exhibit A to the Executive Severance Plan, Table 2) by the annual premium ($18,235.00) that would be payable for the continued receipt of financial planning services which Employee receives as of immediately prior to Employee’s date of termination (as per Executive Severance Plan, Section 3(a)(iii)); and

a cash payment equal to the result of multiplying Employee’s applicable Severance Multiple (as per Exhibit A to the Executive Severance Plan, Table 2) by the annual COBRA premium ($9,351) that would be payable by Employee for continued participation in the Company’s group health plans in which Employee participates immediately prior to Employee’s date of termination (as per Executive Severance Plan, Section 3.(a)(iv)).

Stock Incentives. As additional consideration for Employee entering into this Agreement, and as per the Executive Severance Plan, Section 3.(a)(v), Employee’s unvested and outstanding Company equity awards, inclusive of equity awards under the Jacobs Leadership Long Term Incentive Plan (“LLTIP”) and Employee’s sign-on equity award, that are scheduled to vest within the nine (9) month period following the Separation Date shall continue to vest during such nine (9) month period in accordance with their original vesting schedule irrespective of the termination of Employee’s employment (subject, for the avoidance of doubt, to the satisfaction of any applicable performance criteria). Additionally, as approved by the Company’s Human Resources and Compensation Committee, (a) Employee’s unvested and outstanding restricted stock units that are set to vest on July 1, 2025, November 15, 2025, November 16, 2025, July 1, 2026, November 15, 2026, November 16, 2026 and November 15, 2027 shall continue to vest through their respective vesting dates in accordance with their original vesting schedule irrespective of the termination of Employee’s employment; and (b) Employee’s unvested and outstanding performance stock units that are set to vest on November 16, 2025 and November 15, 2026 shall continue to vest through their respective vesting dates in accordance with their original vesting schedule (and subject to applicable performance metrics) irrespective of the termination of Employee’s employment and, in regards to these performance stock units, Employee shall receive a prorated portion (based on the number of days, during the period between the award date and the vesting date, that Employee was employed by the Company), with the remainder of the performance stock units forfeited at that time. The vesting schedule for the restricted stock units and the performance stock units is set out in Exhibit “B” to this Agreement. Except as explicitly set forth in this Stock Incentives paragraph, Employee acknowledges that from and after the Separation Date, all outstanding stock incentives shall be handled as per applicable plan documents and agreements, including as to forfeiture of Employee’s unvested stock options, unvested restricted stock, unvested performance stock, and/or other unvested stock incentives.

Leadership Performance Plan. Employee shall receive a lump sum cash payment equal to Employee’s annual incentive award based on actual performance (prorated for the number of days worked in a fiscal year through the Separation Date) (as per the Executive Severance Plan, Section 3(a)(ii)). This cash payment shall be paid only after actual performance is determined against the metrics established for Employee’s corporate function for the FY2024 performance period, and will be paid at such time as payments under the Company’s Leadership Performance Plan are paid to employee participants (estimated as mid-December 2024).

Termination of Participation in the Executive Severance Plan. Except as set out in this Agreement, Employee acknowledges and agrees that, effective as of the Separation Date, Employee shall have no further rights, entitlements or interests in the Executive Severance Plan, and Employee is hereby waiving any and all claims, rights, entitlements and interests under or otherwise associated with the Executive Severance Plan, including as to continuing participation after April 15, 2024.

Acknowledgment of Full Payment. Employee acknowledges that the payments and arrangements described herein shall constitute full and complete satisfaction of any and all amounts properly due and owing to Employee as a result of Employee’s employment with Jacobs and/or the termination of that employment, and that in the absence of this Agreement, Employee would not be entitled to, among other things, the payment(s) and benefits specified in this Agreement.
