the consummation of the transactions contemplated hereby or thereby, (ii) any Loan or the use or proposed use of the proceeds therefrom, or (iii) any actual or prospective claim, litigation, investigation or proceeding relating to any of
the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by the Company, and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee,
be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful
misconduct of such Indemnitee or (y) result from a claim brought by the Company against an Indemnitee for breach in bad faith of such Indemnitee’s obligations hereunder or under any other Loan Document, if the Company has

  
 - 12 -

 
obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction. 

(c) Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable law, no Guarantor shall assert, and each
Guarantor hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this
Guaranty, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or the use of the proceeds thereof. No Indemnitee referred to in subsection (b) shall be liable for

Documents or the transactions contemplated hereby or thereby 
 (d) Interest. Any amounts payable by any Guarantor under
this Section 15 or otherwise under this Guaranty if not paid upon demand shall bear interest from the date of such demand until paid in full, at a fluctuating interest rate per annum at all times equal to the Default Rate applicable to
Base Rate Loans to the fullest extent permitted by applicable Law. Any such interest shall be due and payable upon demand and shall be calculated on the basis of a year of 365 or 366 days, as the case may be, and the actual number of days elapsed.

 (e) Payment. All amounts due under this Section 15 shall be payable within ten Business Days after demand
therefor. 
 (f) Survival. The agreements in this Section 15 shall survive the termination of the Commitment
and repayment of all Guaranteed Obligations. 
 SECTION 16 Right of Set-Off. If an Event of Default shall have occurred
and be continuing, the Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever
currency) at any time held and other obligations (in whatever currency) at any time owing by the Lender to or for the credit or the account of any Guarantor against any and all of the obligations of such Guarantor now or hereafter existing under
this Guaranty or any other Guarantor Document to the Lender, irrespective of whether or not the Lender shall have made any demand under this Guaranty or any other Loan Document and although such obligations of such Guarantor may be contingent or
unmatured or are owed to a branch or office of the Lender different from the branch or office holding such deposit or obligated on such indebtedness. The rights of the Lender under this Section are in addition to other rights and remedies (including
other rights of setoff) that the Lender may have. The Lender agrees to notify the affected Guarantor promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff
and application. 
 SECTION 17 Marshalling; Payments Set Aside. The Lender shall not be under any obligation to marshal
any assets in favor of any Guarantor or any other Person or against or in payment of any or all of the Guaranteed Obligations. To the extent that any payment by or on behalf of the Company is made to the Lender, or the Lender exercises its right of
setoff, and such 

  
 - 13 -

 
payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement
entered into by the Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any Insolvency Proceeding or otherwise, then (i) to the extent of such recovery, the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred. 
 SECTION 18 Benefits of Guaranty. This Guaranty is entered into for the sole protection and benefit of the Lender and its successors and assigns, and no other Person (other than any Related Party or
Participant) shall be a direct or indirect beneficiary of, or shall have any direct or indirect cause of action or claim in connection with, this Guaranty. The Lender, by its acceptance of this Guaranty, shall not have any obligations under this
Guaranty to any Person other than the Guarantors, and such obligations shall be limited to those expressly stated herein. 

SECTION 19 Binding Effect; Assignment. 
 (a) Binding Effect. This Guaranty shall be binding upon each Guarantor and its successors and assigns, and inure to the benefit of and be enforceable by the Lender and its successors, endorsees,
transferees and assigns. 
 (b) Assignment. Except to the extent otherwise provided in the Letter Loan Agreement, no
Guarantor shall have the right to assign or transfer its rights and obligations hereunder or under any other Guarantor Documents without the prior written consent of the Lender. The Lender may, without notice to or consent by any Guarantor, sell,
assign, transfer or grant participations in all or any portion of the Lender’s rights and obligations hereunder in connection with any sale, assignment, transfer or grant of a participation by such Lender in accordance with the Letter Loan
Agreement of or in its rights and obligations thereunder and under the other Loan Documents. In the event of any grant of a participation, the Participant (A) shall be deemed to have a right of setoff under Section 16 in respect of

process which may be served in any action or proceeding arising out of or relating to this Guaranty and the other Guarantor Documents in any of the courts in and of the State of New York. Such service may be made by mailing or delivering a copy of
such process to each Guarantor in care of the Process Agent at the Process Agent’s address and such Guarantor hereby irrevocably authorizes and directs the Process Agent to accept such service on its behalf and agrees that the failure of the
Process Agent to give any notice of any such service to such Guarantor shall not impair or affect the validity of such service or of any judgment rendered in any action or proceeding based thereon. As an alternative method of service, such Guarantor
also irrevocably consents to the service of any and all process in any such action or proceeding by the mailing of copies of such process to such Guarantor at its address specified on the signature page hereof. If for any reason the Company shall

RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES OR ANY OF THEM WITH RESPECT TO THIS GUARANTY, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND

make a general reference pursuant to California Code of Civil Procedure Section 638 to a referee (who 

  
 - 15 -

 
shall be a single active or retired judge) to hear and determine all of the issues in such action or proceeding (whether of fact or of law) and to report a statement of decision, provided
that at the option of any party to such proceeding, any such issues pertaining to a “provisional remedy” as defined in California Code of Civil Procedure Section 1281.8 shall be heard and determined by the court, and (b) without
limiting the generality of Section 16, the Guarantors shall be solely responsible to pay all fees and expenses of any referee appointed in such action or proceeding.

provision of this Guaranty or the other Guarantor Documents is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Guaranty shall not be affected or impaired thereby
and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or
unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 
 SECTION 24 Confidentiality. The Lender agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its
Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information
and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent
required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other to the Letter Loan Agreement, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any
action or proceeding relating to this Guaranty or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any
assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under the Loan Documents or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction
relating to the Company, any Guarantor and their respective obligations, (g) with the consent of the applicable Guarantor or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this
Section or (y) becomes available to the Lender on a nonconfidential basis from a source other than the Company, or any Guarantor. For purposes of this Section, “Information” means all information received from any Guarantor
relating to such Guarantor, any of its Subsidiaries or Affiliates or any of their respective businesses, other than any such information that is available to the Lender 

  
 - 16 -

 
on a nonconfidential basis prior to disclosure by such Guarantor, its Subsidiaries or its Affiliates. Any Person required to maintain the confidentiality of Information as provided in this
Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information. By
its acceptance hereof, the Lender acknowledges that (a) the Information may include material non-public information concerning a Guarantor, (b) the Lender has developed compliance procedures regarding the use of material non-public
information and (c) it will handle such material non-public information in accordance with applicable Law, including Federal and state securities Laws. 
 SECTION 25 Future Guarantors. At such time following the date hereof as any Subsidiary of Jacobs (an “Acceding Subsidiary”) is required to accede hereto pursuant to the terms of
Paragraph 2 of the Letter Loan Agreement, such Acceding Subsidiary shall execute and deliver to the Lender an accession agreement substantially in the form of Annex 1 (the “Accession Agreement”), signifying its agreement to
be bound by the provisions of this Guaranty as a Guarantor to the same extent as if such Acceding Subsidiary had originally executed this Guaranty as of the date hereof. 
 SECTION 26 Counterparts. This Guaranty may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. 
 SECTION 27 USA PATRIOT Act Notice. The Lender hereby notifies each
Guarantor that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies such
Guarantor, which information includes the name and address of such Guarantor and other information that will allow the Lender to identify such Guarantor in accordance with the Act. 

IN WITNESS WHEREOF, each Guarantor has executed this Guaranty, as of the date first above written.

and operating margins. Sensitive Information does not include information that is generally available in the public domain, other than as a result of action by the 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.

compliance being a condition of employment.

	3.4	As soon as administratively practical after Completion of the Transaction, the Employee will be nominated for a one time grant of 10,000 shares of Jacobs’

	4.1	As soon as administratively practical after Completion of the Transaction, the Employee will be entitled to participate in the Company’s employee benefit
plans or programs that the Company makes available to its employees generally, subject to applicable law and the terms thereof as in effect from time to time. The Company, in its sole discretion, may modify its employee benefits from time to time.

  

	5.	Paid Time Off 

  

	5.1	The Employee will be entitled to five (5) weeks of paid time off (“PTO”) for each full calendar year of employment under this Agreement and a pro
rata share of such PTO for any partial such year. Scheduling of PTO will be subject to the approval of the person to whom the Employee reports. 

  

	6.	Termination and Dismissal 

  

	6.1	Either the Employee or the Company may terminate the Employee’s employment agreement hereunder for any reason by giving the other party six
month’s written notice of such termination. The notice period will commence on the first day of the month following the delivery of such notice. 

  

	6.2	The Company will, in case of termination of the employment agreement, be entitled to allocate other responsibilities to the Employee or order Employee to
go on paid leave of absence with immediate effect, provided that salary and other fringe benefits will be retained for the duration of the notice period. 

  

	6.3	During the six months after either the Company or the Employee gives the notice of termination described in paragraph 6.1, the Company will not be obliged to
assign any duties to, or provide any work for the Employee and will be entitled to exclude the Employee from any premises of the Company and/or to require him not to communicate with clients, suppliers, employees, agents or
representatives of the Company or any Affiliate, provided that the Company will continue to pay the Employee’s Base Salary and maintain his fringe benefits during such period. During any such period, unless the Company consents in
writing for him to do so, the Employee may not perform any work in any capacity, whether paid or unpaid, for any other person or entity other than the Company or one of its Affiliates, without regard to whether such work is classified as
consulting work or as work as a part-time for full-time employee, nor may the Employee during such six month-period solicit business for any prospective venture with which he plans to become involved. The Parties understand that the intent of
this paragraph is to grant the Company the right to place the Employee on what is referred to as “garden leave” in the event that either he or the Company gives the six month notice of termination described above. The
Employee agrees that, if he violates this “garden leave” provision, the Company, to the fullest extent allowed by law, may withhold any amounts still owed to him by the Company. However, the Company’s withholding of amounts in
accordance with the preceding sentence will not limit its right to claim further damages against the Employee for breach of the paid leave of absence provision or other obligations under this Agreement. 

 

	6.4	For purposes of this Agreement, “Cause” shall be limited to: 

  
 4 

	 	(a)	Gross negligence or willful misconduct in respect to, or a material failure or refusal to continue the performance of, his/her duties and responsibilities as set forth
in this Agreement, which Employee fails to cure within twenty (20) days after having received written notice from the Company of the facts and circumstances that it contends constitute the above conduct; 

 

	 	(b)	Material breach of any provision of this Agreement or of Employee’s Employee Invention and Confidential Information Agreement, which Employee fails to cure within
twenty (20) days after having received written notice from the Company of the facts and circumstances that it contends constitute a material breach; 

  

	 	(c)	The illness or incapacity (or other disability as defined in Jacobs’ disability plan in effect at the time of such disability) of Employee of such a character so
as to disable the Employee from rendering services for a period of more than 90 days (whether or not consecutive) during any 12-month period; 

  

	 	(d)	The death of Employee; 

  

	 	(e)	Material breach of, or material failure to abide by, Jacobs’ Corporate Policy Concerning Business Conduct, Integrity, and Ethics (USA); 

 

	 	(f)	Civil fraud, breach of fiduciary duty involving personal profit, or willful violation of any law, rule or regulation (other than traffic violations or similar
offenses); and/or 

  

	 	(g)	Breach of or failure to abide by Jacobs’ Drug, Alcohol, and Contraband Policy. 

 

	6.5	For purposes of this Agreement, “Good Reason” shall be limited to: 

 

	 	(a)	A reduction in Employee’s Base Salary; or 

  

	 	(b)	the Company’s material breach of any provision of this Agreement, which the Company fails to cure within (20) days after having received written notice from
Employee of the facts and circumstances that he/she contends constitute a material breach of any provision of this Agreement. 

  

	6.6	The Company may discharge the Employee for Cause, without providing him with the six month notice described above. In such case, all Employee’s
rights to salary and fringe benefits will lapse immediately, subject to any rights that Employee may have to be paid for his services performed prior to the date of his dismissal, to purchase extended medical insurance coverage under the
federal law known as COBRA (the Consolidated Omnibus Budget Reconciliation Act), and to receive any vested retirement benefits to which he is entitled under ERISA. 

 

	6.7	If the Company terminates the Employee without Cause the Company will provide the Employee the following:  

 

	 	(a)	Severance for 12 months, which will consist of a lump-sum amount equal to 12 months base salary in effect on the effective date of his termination; or the Company may
pay the severance in twelve monthly payments, subject to taxes and other withholdings required by law and/or authorized by the Employee; and 

  
 5 

	 	(b)	A lump-sum amount equal to the continuation cost of twelve months of COBRA-eligible benefits (collectively “Severance Payment”). 

Notwithstanding any of the foregoing, the Employee’s entitlement to Base Salary and fringe benefits during the paid leave of
absence period and the Severance Payment are conditioned upon his first executing and delivering to the Company a further agreement (or agreements) satisfactory to the Company, including without limitation a general release of all claims due to the
termination of his employment, and his compliance in all respects with his obligations under this Agreement. The Company and the Employee will make a written agreement confirming the final financial settlement related to the termination of
the employment. 
  

	6.8	If the Company terminates the Employee’s employment during the Retention Period without Cause or if the Employee terminates his employment during the
Retention Period with Good Reason, then the Employee shall be entitled to receive a payment (the “Retention Payment”) equal to the amount of base salary the Employee would have received from the date of termination of
employment to the end of the Retention Period (based on the Employee’s base salary as of the date of termination, without regard to any future increases to which the Employee may have been entitled), less any payments received
from the Company under the other provisions of this paragraph 6 or pursuant to applicable law as payment in lieu of notice, severance or other payment related to termination of employment. 

 

	7.	Non-Competition and Non-Solicitation Agreements 

  

	7.1	Employee agrees as follows: 

  

	 	(a)	Employee recognizes and acknowledges that as a key employee he will have access to clients and information that are not generally available to the Company’s
and its affiliated companies’ and successors’ employees; that the market for the type of work that the Company and its affiliated companies and successors are engaged in is limited; that the relationship of the Company and its affiliated
companies and successors with their clients is a significant and valuable asset; and that the use by competitors of the client contacts and information available and entrusted to a key employee would have a detrimental effect on the business of the
Company and its affiliated companies and successors; 

  

	 	(b)	Employee covenants and agrees that during the term of Employee’s employment, and, if Employee’s employment is terminated during the
Retention Period for any reason, for a period of two (2) years immediately following such termination, Employee shall not compete with the Company and its affiliated companies, or any successor, directly or indirectly, alone or as a
member of a partnership, or as an officer, director, stockholder, employee, consultant or representative of any competitive company, or otherwise in any business of the type engaged in by the Company or any of its affiliated companies, for the
period from two years preceding the Effective Date of this Agreement to the date of Employee’s termination of employment in any geographic area where the Company and its affiliated companies are engaged in business;

  
 6 

	 	(c)	The parties intend that the covenant contained in paragraph 7.1(b) above shall be construed as a series of separate covenants, one for each country and for each county
in the United States within the geographic area covered by this paragraph 7.1. Except for geographic coverage, each such separate covenant shall be deemed identical in terms to the covenants contained in paragraph 7.1(b) above. If, in any judicial
proceeding, a court shall refuse to enforce any of the separate covenants deemed included in this paragraph 7, then any such unenforceable covenant shall be deemed eliminated from these provisions for the purpose of those proceedings to the extent
necessary to permit the remaining separate covenants to be enforced; and 

  

	 	(d)	As a point of reference, an interest which amounts to one percent (1%) or less of any class of securities listed on any of the national securities exchanges or
regularly traded over-the-counter, and the value of which does not exceed five percent (5%) of Employee’s net worth, generally would not be regarded as a significant financial interest in a competitor, supplier, or customer
in breach of paragraph 7.1(b) above in the absence of other complicating factors which should cause Employee to recognize that a conflict is present. 

 

	7.2	In consideration for Employee’s eligibility for the Retention Payment, Employee agrees that he shall not during the term of
Employee’s employment, and, if Employee’s employment is terminated during the Retention Period for any reason, for a period of two (2) years immediately following such termination, either directly or
indirectly: 

  

	 	(a)	use or disclose any Sensitive Information to any person, firm or corporation except in the proper course of his duties, as authorized by the Company or its affiliated
companies or successors or as required by law; or 

  

	 	(b)	solicit the services of or hire any officer, director or employee of the Company or its affiliated companies or successors either on behalf of himself or for any other
person, firm or corporation. 

  

	7.3	In consideration for Employee’s eligibility for the Retention Payment, Employee agrees that he shall not during the term of
Employee’s employment, and, if Employee’s employment is terminated during the Retention Period for any reason, for a period of two (2) years immediately following such termination, either directly or
indirectly: 

  

	 	(a)	make known to any person, firm or corporation the names or addresses of any of the customers of the Company or its affiliated companies or successors or any other
information pertaining to them that such recipient would be able to use in competition with the Company or its affiliated companies or successors; or 

  

	 	(b)	call on, solicit or take away, or attempt to call on, solicit or take away any of the customers of the Company or its affiliated companies on whom the Employee
called or with whom he/she became acquainted during his employment either on behalf of himself or for any other person, firm or corporation with the intent to be in competition with the Company or its affiliated companies. 

 

	7.4	 Employee understands and hereby represents that the services to be performed by him under this Agreement are of a special, unique, unusual,
extraordinary and intellectual 

  
 7 

	 	 
character that gives them a peculiar value, the loss of which cannot be reasonably or adequately compensated in damages in an action at law. Employee therefore expressly agrees that in the
event of any material breach or threatened breach of one or more of the covenants set forth in this Agreement, the Company may in addition to the other remedies which may be available to it, whether at law, in equity or otherwise, file a suit in
equity to enjoin Employee from the breach or threatened breach of such covenant. In addition, each of Employee and the Company expressly agrees that in the event of any action or suit seeking enforcement of the provisions of this
Agreement, the prevailing party shall be entitled to recover reasonable attorneys’ fees in connection with such action or suit; provided, however, that a party shall be deemed to be a prevailing party for purposes of the foregoing only if the
applicable court finds in favor of such party in substantially all respects in connection with such action or suit. 

  

	8.	Right to Contract; Conflict of Interest 

  

	8.1	Employee hereby represents and warrants to the Company that: (a) he has full right and authority to enter into this Agreement and to perform his obligations
hereunder; (b) the execution and delivery of this Agreement by the Employee and the performance of the Employee’s obligations hereunder will not conflict with or breach any agreement, order or decree to which Employee
is a party or by which he is bound, and; (c) he is not a party to or bound by any agreement or commitment, or subject to any restrictions (including confidentiality or non-competition restrictions), in connection with any prior employment or
activities. Employee will indemnify and hold the Company harmless, including for all attorneys’ fees and expenses incurred by the Company, in the event that any representation made by him in this paragraph is false.

  

	9.	Mandatory Arbitration Provision 

  

	9.1	 Unless otherwise noted in this paragraph, disputes between the Parties will be submitted to and resolved by binding arbitration with the American
Arbitration Association (“AAA”). Except as to injunctions and other equitable relief, this section on mandatory arbitration applies to any dispute, claim or controversy arising out of or related in any way to this Agreement, including but
not limited to its enforceability, validity, or interpretation. This section on mandatory arbitration will also apply to any claim related in any way to the Employee’s employment with or provision of services to Company or any Affiliate
and to any employment-related claim that the Employee may assert against the Company or any Affiliate; or to any employment-related claim that the Company or any of the Affiliates may assert against the Employee. The arbitration will
be conducted under AAA’s Rules for the Resolution of Employment Disputes, which are incorporated herein unless expressly contradicted by the language of this paragraph and will be held in Houston, Texas. One neutral arbitrator will be selected
by mutual agreement of the Parties. Should the Parties be unable to reach agreement on the arbitrator after 30 days of consultation, the arbitrator will be appointed by the AAA. The arbitrator will provide a written decision setting forth his or her
essential findings and conclusions on which the award is based and judicial review of the arbitration award will be allowed to the extent permitted by any applicable federal, state or local law. Judgment upon the award rendered by the arbitrator may
be entered in any court having jurisdiction. It is specifically agreed that this arbitration provision will be binding on the Employee’s heirs, administrators, and personal representatives, and the Company and its successors and assigns.
This paragraph will be governed by the Federal Arbitration Act. Consistent 

  
 8 

	 	 
with the expedited nature of arbitration, each party to any arbitration filed under this paragraph will, upon the written request of the other party, promptly provide the other with copies of
documents relevant to the issue raised by any claim or counterclaim. Additionally, each party will allow the other party to depose witnesses under that party’s control and will cooperate with the other party in scheduling depositions. Any
dispute regarding discovery, or the relevance or scope thereof, will be determined by the arbitrator. All discovery will be completed within 90 days following the appointment of the arbitrator, unless the arbitrator finds that there is good cause
for extending the discovery period. The remedies and damages that the parties may receive in arbitration will be the same as those the parties could receive in court. Without waiving any remedy under this Agreement, either party may seek from any
court having jurisdiction injunctive relief or any interim or equitable relief that is necessary to protect the rights or property of that party, pending the arbitrator’s final determination on the merits. Any provision of this section on
mandatory arbitration that is found to be unconscionable will be severed and the remainder hereof will be enforced without the severed provision.

	10.5	 The Company and Employee recognize that the laws and public policies of the state law applicable to this Agreement are subject to varying
interpretations and change. It is the intention of the Company and Employee that this Agreement be enforced to the fullest extent permitted by law. Therefore, should a court of competent jurisdiction hold any provision or portion or clause of

 9 

	 	 
provision or clause of this Agreement, or any portion thereof, to be illegal, void or unenforceable because of the scope of such covenant or provision, it is the intention of the parties that the
court will modify such a provision to render its scope legal and enforceable and, in its modified form, such provision will then be enforceable and will be enforced.

 Attachment “A” 

CONFIDENTIAL 
 INCENTIVE BONUS PLAN 
 FOR OFFICERS AND KEY MANAGERS

 Effective 10/1/2010 
 Summary of the Program 
 The purpose of the Jacobs Engineering Group Inc. and its
subsidiaries (“Company”) Incentive Bonus Plan (the “Plan”) is to promote the success of the Company by attracting and retaining highly qualified people who perform to the best of their abilities to achieve Company objectives and
profitability. This program is designed to cover designated officers and key managers of Jacobs Engineering Group Inc. and its subsidiaries. Key managers are defined as management level personnel who do not normally receive overtime compensation and
who are approved for participation by the Chief Executive Officer and the Human Resources and Compensation Committee (“Committee”) of Jacobs’ Board of Directors. 
 Each year a bonus pool is determined by a formula approved by the Committee. From the pool up to 80 percent is allocated to participants in the Plan, with the balance reserved for distribution to
nonparticipating employees who have made an outstanding contribution during the year. The allocation of each participant’s portion of the pool may be up to 50 percent by formula with the balance allocated solely at the discretion of the Chief
Executive Officer. The allocation of the nonparticipant’s portion of the pool is totally at the discretion of the Chief Executive Officer. All award recommendations are approved by the Committee which has sole and absolute discretion to
administer the plan. 
 Bonuses are paid in three annual installments. The first installment is paid approximately three months after the close
of the first fiscal year to which it pertains. A participant is not vested in any future installments. A participant must be employed by the Company at the date each future installment is paid as the bonus is not only for service done in a
particular year but also for services to be rendered in the years when future installments may be paid. The bonus award reflects recognition of performance attained and expected to be attained in the future. If an employee is a participant in the
plan for less than a full year, the measure of his or her bonus will be prorated accordingly. If a participant’s employment is severed from the Company at any time prior to the time a future installment is to be paid, such installment and any
and all 

  
 12 

			
	Page #2	  	CONFIDENTIAL            
	Incentive Bonus Plan	  	

  

 
future installments are automatically forfeited. For the purposes of this program, a participant will be considered employed by the Company for purposes of receiving future installments only if
on the date of payment, the participant is an active full time employee with the Company. 
 Bonus Pool Formula 

The bonus pool is established as a percentage of pretax, pre-bonus earnings above a preset trigger point or hurdle rate. The hurdle rate for each fiscal
year will be established by the Committee. Once the trigger point is reached, the bonus pool accrues at a rate set by the Committee up to 20 percent of pretax, pre-bonus income in excess of the trigger point. When a pretax, pre-bonus earnings
reaches 1.4 times the trigger point, the accrual rate increases to a rate set by the Committee up to 33 percent of pretax, pre-bonus income in excess of 1.4 times the trigger point. The percentage rate used for calculating the trigger point is
established each year based on economic and market conditions in effect at that time. The bonus pool formula is subject to change at any time and is determined at the sole and absolute discretion of the Committee. 

Allocation of Bonus Pool 
 The
portion of the pool allocated to the Plan participants is distributed 50 percent based on their weighted salary (using factors approved by the Committee each year) versus the total weighted salaries of all participants of the plan and 50 percent at
the discretion of the Chairman of the Board and the Chief Executive Officer. The weighted salaries will be determined by multiplying the salary earned while a participant in the plan times the weighting factors as determined by the Chairman, the
Chief Executive Officer and the Committee. 
 If a participant moves from one level to another during the year, the different weighting factors
is applied to the salary earned at each level and prorated. 
 Payments 
 An Award shall be paid at such time or times as determined by the Committee, in its sole and absolute discretion. The Committee may reduce any award up to the date of payment. All payments are subject to
federal, state, or local taxes unless deferred pursuant to the terms of a Company sponsored plan a participant may be eligible for.
