Retirement Transition Agreement by and between Jacobs Engineering Group Inc. and Gary Mandel, dated November 20, 2018

Retirement Date. Employee shall begin a transition to retirement beginning April 1, 2019 (the “Transition Date”), on a modified full-time status basis, and shall retire from Jacobs effective December 31, 2019 (the “Retirement Date”). After the Retirement Date, Employee shall perform no further duties, functions or services for Jacobs.

Resignation of Officer and Director Positions, and Supersession of Prior Agreements and Specified Severance Benefits. Effective with the Transition Date, to the extent such has not already occurred, Employee resigns his executive officer, officer, director and/or managing positions with Jacobs and its affiliated legal entities. By signing this Agreement, Employee also acknowledges and agrees that his Employment Agreement between Jacobs Engineering Group Inc. and Gary Mandel, amended and restated effective December 30, 2017 (“Employment Agreement”), is hereby superseded and replaced in its entirety by this Agreement, except for Paragraphs 7 and Subparagraphs 7.1 through 7.4 of the Employment Agreement (the “Non-Competition and Non-Solicitation Agreements” paragraphs) which, except as permitted by Other Employment Provision, below, shall survive this Agreement and are incorporated herein by reference. Further, by signing this Agreement, Employee acknowledges and agrees that he shall not be entitled to any benefits under the Jacobs Engineering Group Inc. Executive Severance Pay Plan (“ESPP”), that his participation under such ESPP is terminated by mutual consent, that this Agreement satisfies any termination notification obligations that may otherwise exist under the ESPP, and that this Agreement supersedes and replaces entirely any benefits that may otherwise be set out in the ESPP.

Executive Advisor. On October 1, 2018, Employee became a special advisor to Jacobs’ Chief Executive Officer (“CEO”), and as of the Transition Date Employee shall continue in this role on a modified full-time basis, with the expectation that Employee will work 21 hours per week during this period. Employee shall perform this advisory role until December 31, 2019, and his salary between April 1, 2019 and December 31, 2019 (the “EA Period’) shall be $83,333.33 per month. Such salary shall be paid, after applicable tax withholdings and deductions, in conformance with Jacobs’ normal payroll practices. During the EA Period, Employee shall not be eligible to receive any additional incentive compensation, such as cash bonuses or new equity awards, except as provided in Section 5 below to the extent any Fiscal Year 2018 incentive cash award is not paid until after the EA Period begins. The foregoing notwithstanding, nothing in this Agreement shall prohibit Jacobs from granting any voluntary special bonus to Employee in its sole discretion. Employee will accrue paid time off (“PTO”) during the EA Period and be eligible for holiday pay, which PTO accruals and holiday pay will be pro-rated based on Employee’s modified full-time employee status and the number of hours worked.

Termination Payment. Provided that Employee delivers to Jacobs a timely signed supplemental release agreement (“Supplemental Release Agreement”), attached hereto as Exhibit B, covering the employment period between the Effective Date of this Agreement and the Retirement Date, Employee shall receive a lump sum termination payment of $250,000.00 (Two Hundred Fifty Thousand Dollars and Zero Cents), less all applicable tax withholdings and deductions, within 30 days of the effective date of the Supplemental Release Agreement. Employee acknowledges and understands that he cannot sign the Supplemental Release Agreement until on or after the Retirement Date.

Management Incentive Plan and/or Long Term Incentive Plan. By signing below, Employee is not waiving any entitlement to receive a Fiscal Year 2018 Management Incentive Plan Award (estimated payout of $945,000.00), or his additional bonus opportunity award for Fiscal Year 2018 based on synergies achieved through integration following the merger of Jacobs and CH2M (estimated payout of $2,000,000.00), or any vesting under the Fiscal Year 2018 Long Term Incentive Plan which vesting (50% vesting of FY2018 LTIP grant in November 2018, and 50% vesting of FY2018 LTIP grant in November 2019) shall continue through the Retirement Date as per plan. Except as set forth herein, Employee acknowledges and agrees that, to the extent Employee has been and or currently is a participant in the Jacobs Management Incentive Plan (“MIP”) and/or the Jacobs Long Term Incentive Plan (“LTIP”), he will not be eligible to participate in, nor will he receive any awards (whether in cash, stock or other instrument) under, the MIP and/or the LTIP for Fiscal Year 2019 and/or any future year programs. Any unvested restricted stock units and/or performance stock units as of the Retirement Date, if any, shall be forfeited as per plan.

Effect of Termination for Cause or Without Cause. Should Employee’s employment with Jacobs be terminated Without Cause (as defined below) during the EA Period, Employee shall receive any then unpaid benefits under Section 3, Section 4 and Section 5, payable within thirty (30) days of such Without Cause termination date. For purposes of this Agreement, a “Without Cause” termination shall mean any involuntary termination of Employee’s Employment by Jacobs that is for any reason other than for Cause (as defined below), but shall not include any voluntary termination of employment by Employee for reason of retirement, resignation or job abandonment. “Cause” for purposes of this Agreement, shall mean and be limited to Jacobs’ termination of Employee’s employment with Jacobs following the occurrence of any one or more of the following:

Employee is convicted of, or pleads guilty or nolo contendere to, a felony;

Employee willfully and continually fails to substantially perform his duties with Jacobs (other than any such failure resulting from his incapacity due to physical or mental illness) after a written demand for substantial performance is delivered to him by the Chief Executive Officer which specifically identifies the manner in which the Chief Executive Officer believes that Employee has not substantially performed his duties;

Employee willfully engages in conduct that is materially injurious to Jacobs or its affiliates, monetarily or otherwise;

Employee commits an act of gross misconduct in connection with the performance of his duties to Jacobs;

Employee’s willful violation of any material Jacobs policy; or

Employee materially breaches any employment, confidentiality, restrictive covenant or other similar agreement between Jacobs and Employee.

Stock Incentives. By signing below, Employee is not forfeiting any continued vesting through the Retirement Date of any restricted stock, performance stock and/or stock incentives he may have received prior to the Transition Date, nor is Employee forfeiting the ability to exercise any stock options through any applicable exercise date provided in the applicable stock option award agreement. Employee acknowledges that from and

Other Employment. If Employee accepts other employment without the prior written permission of Jacobs’ CEO prior to the Retirement Date, such action shall be deemed a voluntary resignation by Employee effective as of the date of his other employment, and Employee shall not be eligible to receive any of the benefits described in this Agreement that are then unpaid, including those specified in Section 3, Section 4 and/or Section 5 above, and all unvested benefits under any Jacobs benefit plan shall be handled, including with respect to forfeiture, as per plan in accordance with such voluntary resignation. The foregoing notwithstanding, Jacobs agrees that Employee may contract on a non-employee basis (e.g., as a Form 1099 contractor) with WorleyParsons at any time following the close of the transaction involving Jacobs’ sale of its ECR line of business to WorleyParsons, provided that Employee submits the contract to Jacobs’ CEO and SVP for Global Human Resources thirty days in advance of the date proposed for commencing such contractor relationship between Employee and WorleyParsons and further provided that Jacobs thereafter agrees to permit Employee to enter into that contractor relationship, which permission shall not be unreasonably withheld by Jacobs.

Employee Death Prior To Retirement Date. In the event of Employee’s death prior to the Retirement Date, the following benefits will be paid to his estate within thirty days after Jacobs receives notice of such death:

all of Employee’s accrued PTO;

any unpaid compensation for the services described in the Executive Advisor Section above; and

the termination payment described in the Termination Payment Section, above. In the event Employee were to die prior to payment of any Fiscal Year 2018 cash incentives identified in the Management Incentive Plan and/or Long Term Incentive Plan Section, above, his estate shall receive such cash incentive (assuming such cash incentives have been awarded by Jacobs for Fiscal Year 2018 to participants under the applicable plans), within thirty days of the date payouts are made under the applicable incentive plan to other participants.

Vested Benefits. Nothing herein shall deprive Employee of any vested benefits that Employee has in the Jacobs' Section 401(k) or other employee benefit plan. Employee cannot withdraw or transfer funds in the 401(k) plan until after the Retirement Date, except as may be otherwise permitted under the terms of that plan.

Executive Deferred Compensation. Employee acknowledges that that under Section 409A of the Internal Revenue Code, as long as he does not experience a Separation from Service under Section 409A through the Retirement Date, then no distributions will be triggered before the Retirement Date. Employee understands that a participant in the Executive Deferral Plan (“EDP”) shall be considered to have experienced a termination of employment (and thus a Separation of Service) when the facts and circumstances indicate that the participant and his employer reasonably anticipate that either (a.) no further services will be performed for the employer after a certain date, or (b.) that the level of bona fide services the participant will perform for the employer after such date will permanently decrease to no more than 20% of the average level of bona fide services performed by such participant over the immediately preceding 36-month period. Employee and Jacobs agree that it is expected that Employee will work 21 hours per week from the Transition Date through the Retirement Date. The foregoing notwithstanding, Employee acknowledges and understands that if the facts and circumstances indicate either (a.) or (b.), above, distributions under the EDP will occur as per plan, irrespective of whether Employee continues in his employment status with Jacobs through the Retirement Date. Employee also acknowledges that a Separation from Service under Section 409A will occur upon Employee’s Retirement Date, and distributions under the EDP will occur as per plan.

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 his employment with Jacobs through the Effective Date of this Agreement, 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.

Other Employee Benefits. Nothing herein shall deprive Employee of any vested benefits that Employee has in the Jacobs' Section 401(k) or other employee benefit plan. Employees age 55 or older with at least five (5) years of service as of the Retirement Date may be eligible for participation in the Jacobs Aetna Retiree Health Access Program, subject to plan rules and availability. Employee should consult with Jacobs Employee Solutions & Information (“JESI”) regarding this program and eligibility.

Right to Elect Continued Coverage. Upon his Retirement Date, Employee may elect to continue health insurance coverage (medical, dental, vision, employee assistance program, and healthcare flexible spending account) as permitted under COBRA. Information on the COBRA Program and the cost to continue coverage will be mailed to Employee by Jacobs’ Corporate Human Resources Department following his Retirement Date. Employee will have 60 days after receipt of this information to elect COBRA participation, retroactive to the termination of Employee’s employment status. Employee should retain Employee’s medical cards if Employee plans to continue coverage. Employee should contact Jacobs’ Human Resources Department regarding conversion rights or porting rights for life and accident insurance coverage following the Retirement Date.

Non-Disclosure of Trade Secrets, Confidential and Proprietary Information. The termination of Employee’s employment does not terminate Employee’s obligations under the Employee Invention and Confidential Information Agreement (the “EICI Agreement”), the Jacobs Code of Conduct and/or this Agreement. Specifically, Jacobs may enforce the confidentiality provisions of the EICI Agreement, the Jacobs Code of Conduct and/or this Agreement even though Employee leaves its employ.

All business development and client information within the exclusive control of Jacobs, including but not limited to:

Current and prospective customer lists;

Current and prospective business projects;

Pricing, rates, schedules and method of bidding on individual projects;

Technical details and status reports involving current and prospective projects;

Contracting strategies, philosophies and/or techniques;

Salary rates and benefit levels for Jacobs’ employees;

Employment and recruitment policies of Jacobs; and

Internal policies and procedures utilized by Jacobs in performing business projects and consulting work.

Strategic business plans and marketing initiatives of Jacobs which are not general public knowledge.

Any other confidential, proprietary, technical data developed by Employee or disclosed to Employee by Jacobs during Employee’s employment, whether pertaining to specific projects with which Employee was involved or otherwise.

Immunity Under the Defend Trade Secrets Act of 2016. The federal Defend Trade Secrets Act of 2016 provides immunity to Employee in certain circumstances for limited disclosure of Jacobs’ trade secrets:

in confidence, either directly or indirectly to a federal, state or local government official, or to an attorney, “solely for the purpose of reporting or investigating a suspected violation of law,” or

“in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.”

Employee may disclose the trade secret to his attorney, and

Employee may use the information in related court proceedings, as long as Employee files documents containing the trade secret under seal, and does not otherwise disclose the trade secret “except pursuant to court order.”

Entire Agreement; Choice of Law. This Agreement and the Supplemental Release Agreement constitute the entire agreements between the parties pertaining to the subject matter contained therein and, except as explicitly set forth in this Agreement and the Supplemental Release Agreement, supersede all prior and contemporaneous agreements, representations, and understandings of the parties. No provision of this Agreement may be modified, waived or discharged unless such modification, waiver or discharge is agreed to in writing signed by Employee and Jacobs’ CEO. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the State of Texas (without giving effect to its conflicts of laws, rules or principles) and no failure or delay in exercising any right, power or privilege hereunder shall operate or a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder.

Severability. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect.

In further consideration of the foregoing, Employee (on behalf of himself and his agents, heirs, successors, assigns, executors and/or administrators) hereby releases and discharges Jacobs and its affiliated companies, subsidiaries, and Employee Benefit Plans (as defined below) and their respective present and former officers, directors, employees, shareholders, agents, representatives, consultants, insurers, plan administrators, trustees, fiduciaries, attorneys, successors and assigns (each individually a “Releasee” and collectively “Releasees”) from any and all matters, claims, demands, causes of action, debts, liabilities, controversies, judgments and suits of every kind and nature whatsoever, foreseen or unforeseen, known or unknown, whether in law or in equity, which Employee has or may have against the Releasees.

Individual Agreement. This Agreement has been individually negotiated and is not part of a group exit incentive or other termination program.

Entire Understanding; No Changes; Legal Review; Sophisticated Parties. Employee and Jacobs acknowledge that this Agreement and the Supplemental Release Agreement sets forth the entire understanding between them. Neither party has relied upon any representation or statement with respect to the subject matter hereof, written or oral, not set forth in this Agreement and the Supplemental Release Agreement. This Agreement may not be changed orally, but only by a specific written agreement signed by the party against whom enforcement of any waiver, change, modification, extension, or discharge is sought.

Non-Disparagement. Employee agrees that he will not in any way disparage Jacobs, including current or former officers, directors, agents and/or employees of Jacobs, nor will Employee make or solicit any comments, statements or the like to the media or to others, that may be considered to be derogatory or detrimental to the good name or business reputation of Jacobs. Employee’s non-disparagement obligations under this Agreement are not intended to interfere with or restrict Employee’s ability to communicate with any administrative, regulatory, governmental or law enforcement agency, or from testifying under the power of a subpoena issued from a court of competent jurisdiction.

No Solicitation of Jacobs Employees. Employee agrees and warrants that he will not, through the Retirement Date and for a period of one (1) year following the Retirement Date, either directly or indirectly, for himself or on behalf of any third party, solicit, induce, recruit, or cause another person in the employ of Jacobs to terminate his or her employment for the purpose of joining, associating or becoming employed with any business or activity which is in competition with any business or activity engaged in by Jacobs.

No Solicitation of Jacobs Clients. Employee agrees and warrants that he will not, through the Retirement Date and for a period of one (1) year following the Retirement Date, either directly or indirectly, for himself or on behalf of any third party, solicit, induce, recruit, encourage or otherwise endeavor to cause or attempt to cause any client, vendor or contractor of Jacobs to modify, alter and/or terminate its relationship with Jacobs.

Employee acknowledges that upon the Retirement Date, he shall return all Jacobs property, proprietary/confidential information, papers, manuals/notebooks, electronically stored data, software, media, documentation, diskettes, computer equipment and related devices, keys, credit cards, government contractor card and phone cards, and any Jacobs equipment or items to Jacobs.

Sensitive Information. Employee recognizes that in Employee’s role(s) with the Jacobs, Employee has occupied a position of trust with respect to business information of a highly sensitive and confidential nature, including but not limited to, names and duties of key personnel, business and growth/expansion plans, marketing and business development initiatives and prospects, financial results and forecasts, bidding information, cost and charging rates and their make up and structure, customer lists, and profit and operating margins (“Sensitive Information”). (Sensitive Information does not include information that is generally available in the public domain, other than as a result of any action by Employee; provided, however, Sensitive Information shall not be deemed to be in the public domain merely because individual features of it are in the public domain unless the combination itself and the principle of operation are also in the public domain.)

Disclose any Sensitive Information to any person, firm or corporation; or

For a period of two (2) years immediately following the Retirement Date, make known to any person, firm or corporation the names or addresses of any of the customers of Jacobs or Jacobs’ affiliated companies or any other information pertaining to them that such recipient would be able to use in competition with Jacobs or Jacobs’ affiliated companies; or

Work for a competitor on any proposal, bids, statements of qualifications, or other business development tasks (collectively, “proposals”) that are open and not yet awarded as of the Transition Date and/or Retirement Date that Jacobs is exploring, pursing and/or bidding upon (collectively, “open pursuits”) and about which Employee learned of Jacobs’, its clients’ and/or its business affiliates’ Sensitive Information. Employee agrees that he shall remove himself/herself from working, directly or indirectly, on any such open pursuits for a competitor since it would not be possible for Employee to assist a competitor in submitting any proposals or refining offers on the same open pursuits without using and inevitably disclosing Jacobs’, its clients’ and/or its business affiliates’ Sensitive Information. Subject to any other provisions in this Agreement, nothing in this paragraph prohibits Employee from working on any proposals for a competitor company where the proposals are initiated or requested by the soliciting party after the Retirement Date.

Voluntary Agreement. EMPLOYEE UNDERSTANDS THAT THIS AGREEMENT INVOLVES THE KNOWING AND VOLUNTARY RELEASE OF KNOWN AND UNKNOWN CLAIMS BY EMPLOYEE AGAINST JACOBS. EMPLOYEE UNDERSTANDS THAT HE HAS THE RIGHT TO, AND HAS BEEN GIVEN THE OPPORTUNITY TO, CONSULT WITH AN ATTORNEY OF HIS CHOICE.
