Jacobs Solutions Inc. Executive Deferral Plan, effective January 1, 2023

    Page

The purpose of this Plan is to provide specified benefits to a select group of management and highly compensated Employees who contribute materially to the continued growth, development, and future business success of Jacobs Engineering Group Inc. and its participating Affiliates. This Plan is unfunded for tax purposes and for purposes of Title I of ERISA. This Plan restatement is generally effective with respect to compensation deferred beginning January 1, 2023. The prior restatement was effective with respect to compensation deferred beginning January 1, 2018 and replaced the Company’s 2005 Executive Deferral Plan with respect to any benefits provided therein to Employees; the 2005 Executive Deferral Plan continues to govern compensation deferred after December 31, 2004 and before January 1, 2018. Notwithstanding the two preceding sentences and for the avoidance of doubt, the administrative and legal provisions of the Plan including, without limitation, Articles 8 and 10-15, apply to the prior Jacobs Executive Deferral Plans (adopted beginning in 1991), except to the extent such provisions would cause an amount grandfathered under Code section 409A to lose such grandfathered status.

Effective April 26, 2019 (or such other “Closing Date” applicable under the Stock and Asset Purchase Agreement dated October 21, 2018 between Jacobs Engineering Group Inc. and WorleyParsons Ltd.), benefits and liabilities under the Plan (including, for the avoidance of doubt, under the 2005 Executive Deferral Plan and any other predecessor plans) relating to any “Transferred Employees” (as defined in such Stock and Asset Purchase Agreement) are transferred to the plan established by WorleyParsons Ltd. (or one of its affiliates) to pay such benefits. Pursuant to Section 10.5 of the Plan, neither the Company, its subsidiaries or affiliates, nor the Plan or Trust, shall have any remaining responsibility with respect to such transferred benefits and liabilities, and such Transferred Employees shall cease to be eligible to participate in this Plan as of the Closing Date. The transfer of employment in connection with the transaction shall not constitute a Separation from Service and therefore will not be a distribution event under the Plan.

For purposes of this Plan, unless otherwise clearly apparent from the context, the following phrases or terms shall have the following indicated meanings:

1.1    "Account Balance" shall mean, at any given time, the balance in a Participant’s Deferral Account and, if applicable, Employer Contribution Account. The Account Balance shall be a bookkeeping entry only and shall be utilized solely as a device for the measurement and determination of the amounts to be paid to a Participant, or his or her designated Beneficiary, pursuant to this Plan.

1.2    "Administrator" shall mean the administrator described in Sections 11.1 and 11.2.

1.3    "Affiliate" shall mean a corporation, trade or business which is, together with the Company, a member of a controlled group of corporations or an affiliated service group or under common control (within the meaning of Code section 414(b), (c) or (m)), but only for the period during which such other entity is so affiliated with the Company. For purposes of determining a controlled group of corporations under Code section 414(b), the language “at least 50 percent” shall be used instead of “at least 80 percent” each place it appears in Code section 1563(a)(1), (2), and (3), and in applying Treas. Reg. § 1.414(c)-2 for purposes of determining trades or businesses (whether or not incorporated) that are under common control for purposes of Code section 414(c), “at least 50 percent” shall be used instead of “at least 80 percent” each place it appears in Treas. Reg. § 1.414(c)-2.

1.4    "Annual Bonus" shall mean a Participant’s bonus relating to services performed during any Fiscal Year, whether or not paid in such Fiscal Year, under any Employer's annual bonus, incentive bonus and cash incentive plans, to the extent such bonus is specified as eligible under the Plan.

1.5    "Annual Installment Method" shall be an annual installment payment over the number of years selected by the Participant in accordance with this Plan, calculated as follows:

(a)    Initial Valuation Date. For the Plan Year in which payments begin, the Account Balance of the Participant (or, with respect to Equity Pay shares deferred, the number of shares payable over the installment period) shall be calculated as of the close of business on the last business day of the month immediately preceding the month in which payments are scheduled to begin.

(b)    Subsequent Valuation Dates. For subsequent Plan Years: (1) with respect to Equity Pay shares deferred and dividend equivalents thereon, the number of shares and amount payable shall be calculated as of the close of business on the last business day of the month immediately preceding the month in which payment is scheduled, and (2) otherwise, the Account Balance of the Participant shall be calculated as of the close of business on the last business day of the preceding Plan Year.

(c)    Amount of Annual Installment. With respect to Equity Pay shares deferred and dividend equivalents thereon, the annual installment shall be calculated as the total number of shares and amount of dividend equivalents as of the valuation date, divided by the remaining number of annual installments payable. Otherwise, the annual installment for each Plan Year shall be calculated by multiplying the balance as of the valuation date by a fraction, the numerator of which is the number of monthly payments to be made during the Plan Year, and the denominator of which is the remaining number of monthly payments due the Participant or Beneficiary. For purposes of determining the number of shares payable with respect to Equity Pay, the number of shares shall be rounded down to the next highest whole number of shares.

By way of example with respect to amounts other than Equity Pay, if the Participant elects a 10-year Annual Installment Method and payments begin in July 2024, the 2024 payment shall be 6/120th of the Account Balance, calculated as of June 30, 2024. In 2025, the payment shall be 12/114ths of the Account Balance, calculated as of December 31, 2024. Each annual installment paid shall be divided by the number of monthly payments to be made during the year, and the resulting number shall be the monthly installment payment that shall be paid each month of the Plan Year to which such annual installment relates. Subject to the payment provisions of Section

5.2 or 6.2, as the case may be, the monthly installment payment shall be paid on the first day of the month to which it relates.

By way of example with respect to Equity Pay deferrals paid as shares, if the Participant elects a 10-year Annual Installment Method and payments begin in July 2025, the 2025 payment shall be 1/10th of the total number of shares, calculated as of June 30, 2025. If the total number of shares as of such date is 1,455, the 2025 payment shall be 145 shares (rounded down from 145.5). In 2026, the payment shall be 1/9th of the total number of shares, calculated as of June 30, 2025.

1.6    "Base Annual Salary" shall mean the annual cash compensation relating to services performed during any calendar year, whether or not paid in such calendar year, and excluding bonuses, commissions, overtime, fringe benefits, stock options, relocation bonus and/or expenses, incentive payments, non-monetary awards, directors fees and other fees, automobile and other allowances paid to a Participant for employment services rendered (whether or not such allowances are included in the Employee’s gross income). Notwithstanding the foregoing or any provision in Article 9, Base Annual Salary shall not include any amount paid following a Participant’s Separation from Service, except for Base Annual Salary paid for the pay period in which the Participant’s Separation from Service occurs. Base Annual Salary shall be calculated before reduction for compensation voluntarily deferred or contributed by the Participant pursuant to all qualified or non-qualified plans of any Employer and shall be calculated to include amounts not otherwise included in the Participant's gross income under Code Sections 125, 402(e)(3), 402(h), or 403(b) pursuant to plans established by any Employer; provided, however, that all such amounts will be included in compensation only to the extent that, had there been no such plan, the amount would have been payable in cash to the Employee.

1.7    "Beneficiary" shall mean one or more persons, trusts, estates or other entities, designated in accordance with Article 8, that are entitled to receive benefits under this Plan upon the death of a Participant.

1.8    "Beneficiary Designation Form" shall mean the form (written or electronic) established from time to time by the Administrator that a Participant completes, executes and submits to the Administrator to designate one or more Beneficiaries.

1.11    "Claimant" shall have the meaning set forth in Section 13.1.

1.14    "Company" shall mean Jacobs Engineering Group Inc. and any successor to all or substantially all of the Company’s assets or business.

1.15    "Deduction Limitation" shall mean the amount above which distributions otherwise payable to a Participant (or his or her Beneficiary) under the Plan, when combined with other compensation

paid to a Participant (or his or her Beneficiary) for a taxable year, would not be deductible by the Employer (or any Affiliate) by reason of the limitation imposed by Code Section 162(m). The Deduction Limitation shall be determined by the Company in good faith. Once an amount has been determined by the Company not to be deductible because of the Deduction Limitation, the Company may defer the amount that would otherwise be paid to a Participant (or his or her Beneficiary). Any amounts so deferred will remain in the Participant’s Account Balance, and shall be entitled to continued crediting and debiting of additional amounts in accordance with Section 3.5 below. The amounts so deferred and amounts credited thereon shall be distributed to the Participant or his or her Beneficiary during the first year, as determined by the Company in good faith, in which the deductibility of such payment will not be barred by application of Section 162(m). Notwithstanding any other provision in this Plan, to the extent consistent with Section 15.20, the Deduction Limitation shall not apply to distributions that become payable after a Change in Control.

1.16    "Deferral Account" shall mean (i) the sum of all of a Participant's Deferral Amounts, plus or less, as the case may be, (ii) amounts credited or debited in accordance with all the applicable crediting provisions of this Plan that relate to the Participant’s Deferral Account, less (iii) all distributions made to the Participant or his or her Beneficiary pursuant to this Plan that relate to his or her Deferral Account.

1.21    “Employer Contribution” shall mean an amount, if any, credited to a Participant’s Employer Contribution Account, as determined by the Company or Employer in its discretion. Such Employer Contribution may, for example, include an additional contribution for a Plan Year or an award granted to an eligible Employee as an inducement to remain employed by the Employer for a specified period of time or subject to certain performance conditions.

1.22    “Employer Contribution Account” shall mean the (i) sum of any Employer Contributions made to the Plan in accordance with Section 3.1(d), plus or less, as the case may be (ii) amounts credited or debited in accordance with all the applicable crediting provisions of this Plan that relate to the Participant’s Employer Contribution Account, less (iii) all distributions made to the Participant or his or her Beneficiary pursuant to this Plan that relate to his or her Employer Contribution Account.

1.28    "Participant" shall mean any Employee (i) who is selected to participate in the Plan, (ii) who elects to participate in the Plan, (iii) who executes an Election Form and a Beneficiary Designation Form, (iv) whose executed Election Form and Beneficiary Designation Form are accepted by the Administrator, (v) who commences participation in the Plan, and (vi) whose participation in the Plan has not terminated. A spouse or former spouse of a Participant shall not be treated as a Participant in the Plan or have an account balance under the Plan, even if he or she has an interest in the Participant's benefits under the Plan as a result of applicable law or property settlements resulting from legal separation or divorce.

1.29    "Plan" shall mean this Jacobs Executive Deferral Plan, which shall be evidenced by this instrument, as it may be amended from time to time; provided, however, that the Plan will be treated as one or more plans to the extent such treatment, in the sole discretion of the Committee, is required or otherwise necessary or appropriate to comply with law, including Code section 409A. Unless the context requires otherwise, any reference herein to the Plan shall include the entire Plan and each portion thereof that is a separate plan pursuant to the foregoing sentence.

1.31    "Pre-Retirement Survivor Benefit" shall mean the benefit set forth in Article 6.

1.34    "Separation from Service" shall mean “separation from service” as such term is defined in Code section 409A and guidance thereunder. In furtherance of the foregoing, in determining whether a Separation from Service has occurred, the following provisions apply:

(a)    For a Participant who provides services as an Employee, a Separation from Service shall occur when such Participant has experienced a termination of employment with the Employer and all Affiliates. A Participant shall be considered to have experienced a termination of employment when the facts and circumstances indicate that the Participant and his or her Employer reasonably anticipate that either (i) no further services will be performed for the Employer and all Affiliates after a certain date, or (ii) that the level of bona fide services the Participant will perform for the Employer and all Affiliates 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 (or the full period of services to the Employer if the Participant has been providing services to the Employer and all Affiliates less than 36 months).

(b)    If a Participant is on military leave, sick leave, or other bona fide leave of absence, the employment relationship between the Participant and the Employer shall be treated as continuing intact, provided that the period of such leave does not exceed 6 months, or if longer, so long as the Participant retains a right to reemployment with the Employer under an applicable statute or by contract. If the period of a military leave, sick leave, or other bona fide leave of absence exceeds 6 months and the Participant does not retain a right to reemployment under an applicable statute or by contract, the employment relationship shall be considered to be terminated for purposes of this Plan as of the first day immediately following the end of such 6-month period. In applying the provisions of this paragraph, a leave of absence shall be considered a bona fide leave of absence only if there is a reasonable expectation that the Participant will return to perform services for the Employer.

(c)    If a Participant provides services for an Employer as both an Employee and as a member of a board of directors, to the extent permitted by the Treasury Regulations, the services provided by such Participant as a director shall not be taken into account in determining whether the Participant has experienced a Separation from Service as an Employee.

1.35    “Service” shall mean the period of time commencing on a Participant’s initial date of service as an Employee, and ending on the date of the Participant’s Retirement, Termination of Employment, or death. In the case of a Participant who returns to service following a Termination of Employment, Service shall include both the Participant’s earlier Service and the period commencing on the Participant’s date of return and ending on the date of the Participant’s subsequent Retirement, Termination of Employment, or death.

1.36    "Short-Term Payout" shall mean the payout set forth in Section 4.1.

1.37    "Termination Benefit" shall mean the benefit set forth in Article 7.

1.38    "Termination of Employment" shall mean a Separation from Service for any reason other than Retirement, death or an authorized leave of absence.

1.39    "Trust" shall mean one or more trusts established to hold Plan assets (whether or not in combination with assets of another plan), including pursuant to that certain Master Trust Agreement for the Executive Deferral Plan, dated as of June 1, 1991 between the Company and the trustee named therein, as amended from time to time, or any successor thereto.

1.40    "Unforeseeable Financial Emergency" shall mean severe financial hardship to a Participant resulting from an illness or accident of the Participant or the Participant’s spouse or dependent (as defined in Section 152 of the Code, without regard to Sections 152(b)(1), (b)(2), and (d)(1)(B)) of the Participant, loss of the Participant’s property due to casualty, or other similar extraordinary and unforeseeable circumstances arising as a result of events beyond the control of the Participant, as determined in the sole discretion of the Administrator.

2.1Selection by Committee. The Committee, in its sole discretion, shall establish eligibility requirements for participation in the Plan (including portions of the Plan). Participation in the Plan shall be limited to a select group of management and highly compensated Employees of the Employers or the Company.

2.2Enrollment Requirements. As a condition to participation, each selected Employee shall complete, execute and submit to the Committee an Election Form and a Beneficiary Designation Form, within the time period set by the Committee, in its sole discretion, for the purpose of returning documents and forms. In addition, the Committee shall establish from time to time such other enrollment requirements as it determines in its sole discretion are necessary.

2.3Eligibility; Commencement of Participation. A Participant shall commence participation in the Plan on the first day of the Plan Year following the date on which he or she has (i) satisfied all Enrollment Requirements and (ii) has had his or her Election Form and Beneficiary Designation Form accepted by the Committee. Notwithstanding the previous sentence, the Committee may, in its sole and absolute discretion and only to the extent consistent with Section 15.20, permit:

(a)    a new Employee to commence participation in the Plan and defer Base Annual Salary (but not the Participant’s Annual Bonus) in the first pay period following his or her satisfaction of (i) and (ii) above, but only with respect to services to be performed subsequent to the election and only if the election is made within 30 days after the date the Employee becomes eligible to participate; and/or

(b)    an Employee to commence participation in the Plan mid-Plan Year in order to defer Equity Pay in accordance with Section 3.2(b) or receive an Employer Contribution in accordance with Section 3.1(d).

2.4Participants Who Become Ineligible. If the Committee determines in good faith that a Participant no longer qualifies as a member of a select group of management or highly compensated employees, as membership in such group is determined in accordance with Sections 201(2), 301(a)(3) and 401(a)(1) of ERISA, the Committee shall have the right, in its sole discretion, to prevent the Participant from making future deferral elections. However, any existing deferral elections made by the Participant will remain in effect for the remainder of the Plan Year (or other applicable deferral period) of the Participant’s change in status, and payment of the Participant’s Account Balance will proceed as set forth elsewhere in the Plan.

3.1Deferral Election.

(a)    Minimum and Maximum Deferral Commitment. A Participant may make an irrevocable election to defer, as his or her Deferral Amount, an amount of Base Annual Salary and/or Annual Bonus that may not be less than the minimum Deferral Amount, nor more than the maximum Deferral Amount, as set by the Committee prior to the beginning of the Plan Year and set forth in the Election Form for the Plan Year. In addition, a Participant may make an irrevocable election to defer Equity Pay as part of his

or her Deferral Amount, subject to any minimum and/or maximum deferral set by the Committee or in the applicable Election Form.

(b)    Short Plan Year. If a Participant first becomes a Participant after the first day of a Plan Year, the minimum Base Annual Salary deferral shall be the minimum Deferral Amount set forth in subsection (a), unless otherwise determined by the Committee.

(c)Other.

(i)Notwithstanding the foregoing, if a Participant first becomes a Participant after the first day of a Plan Year, the maximum Deferral Amount, with respect to Base Annual Salary and Annual Bonus shall be limited to the amount of compensation not yet earned by the Participant as of the date the Participant’s Election Form is accepted by the Committee.

(ii)Notwithstanding any other provision in this Plan, deferrals shall be a fixed percentage of the applicable Base Annual Salary, Annual Bonus, or Equity Pay. Except as otherwise provided on the Election Form, for Equity Pay that is settled in shares of stock, the number of shares deferred shall be rounded down to the next highest whole number of shares.

(d)Employer Contributions. The Employer may elect to make an Employer Contribution for any Plan Year in such amount and subject to such conditions as it determines in its sole discretion. Except as otherwise determined by the Employer, an Employer Contribution will be paid in accordance with the Participant’s distribution election (or subsequent payment election in accordance with Section 5.2) for the Plan Year for which such Employer Contribution is made but without regard to any Short-Term Payout election that otherwise might apply. Notwithstanding the preceding sentence and to the extent permitted by the Committee and on an Election Form, a Participant may elect the time and form of payment of an Employer Contribution as a Short-Term Payout under Section 4.1, Retirement Benefit under Article 5, and/or Pre-Retirement Survivor Benefit under Article 6; provided, however, that:

(i)Such election is made and irrevocable by the deadlines consistent with those set forth in Section 3.2 (including the fiscal year compensation, performance-based compensation, or 12-month vesting period deadlines in Section 3.2(b));

(ii)The Short-Term Payout year must be no earlier than the year in which the Employer Contribution is fully vested, and payment upon Unforeseeable Financial Emergency under Section 4.3 shall be available only for fully vested amounts; and

(iii)To the extent that the Participant is permitted to subsequently change his or her payment election, such change may be made by the Participant submitting a new Election Form to the Committee, provided that any such Election Form is submitted at least one (1) year prior to the otherwise applicable payment date and delays the Participant’s initial payment by a period of at least five years. For purposes of such election changes, the right to a series of installment payments shall be treated as the right to a single payment.

3.2    Timing of Deferral Elections. A Participant’s election must be received by the Committee no later than the deadline it specifies. In no event will such date be later than the last day of the Plan Year preceding the Plan Year in which the services begin to be performed for which the Base Annual Salary is paid or for which the Annual Bonus or Equity Pay is awarded (which, in the case of Equity Pay, typically is the year in which the Equity Pay is granted); provided, however:

(a)    Newly eligible Participants may make their initial deferral elections as provided in Section 2.3; and

(b)    To the extent permitted by the Committee, Participants may elect to defer compensation no later than the following deadline:

(i)    the last day of the Company’s taxable year that ends immediately before the start of the period for which the deferred compensation is considered “fiscal year compensation” (within the meaning of Treas. Reg. § 1.409A-2(a)(6));

(ii)    the date that is six months before the end of the applicable performance period, to the extent the deferred compensation is performance-based compensation (within the meaning of Code section 409A(a)(4)(B)(iii)); or

(iii)    the thirtieth (30th) day after the grant date, to the extent the deferred compensation is subject to a condition requiring the Participant to continue to provide services for a period of at least 12 months from the grant date and provided that such election also is at least 12 months in advance of the earliest date at which the forfeiture condition on such deferred compensation would otherwise lapse (consistent with Treas. Reg. § 1.409A-2(a)(5));

and provided further that, notwithstanding the terms of an applicable Equity Pay award agreement or other underlying deferred compensation and to the extent necessary to comply with Code Section 409A, for purposes of vesting or payment of such deferred compensation upon either disability or change in control, the terms “disability” and “change in control” shall have the applicable meanings defined in Section 409A, but only to the extent inconsistent with the otherwise applicable definitions and only to the minimum extent necessary to comply with Section 409A as determined by the Committee.

3.3    Withholding of Deferral Amounts. For each Plan Year, the Deferral Amount shall be withheld at the time the Base Annual Salary or Annual Bonus is or otherwise would be paid to the Participant. With respect to Equity Pay, the Deferral Amount shall be withheld at the time the shares underlying the Equity Pay are or would have been issued (or, if the Equity Pay is payable in cash, at the time the Equity Pay is or would otherwise have been paid).

3.4    Vesting. A Participant shall at all times be 100% vested in his or her Deferral Account and will vest in his or her Employer Contribution Account in accordance with the terms of the underlying Employer Contribution.

3.5    Crediting/Debiting of Account Balances. In accordance with, and subject to, the rules and procedures that are established from time to time by the Administrator, in its sole discretion, deferral amounts shall be credited or debited to a Participant’s Account Balance in accordance with the following rules:

(a)    Election of Measurement Funds. At the time an Employee becomes a Participant in the Plan, he or she may designate one or more Measurement Funds which shall be used to determine what additional amounts are to be credited or debited, as the case may be, to his or her Account Balance. Such designations shall apply to the Deferral Amount, as such amounts are deferred by the Participant, and shall remain in force until changed by the Participant in accordance with the policies and procedures as set forth by the Administrator, from time to time, which policies and procedures may be changed, modified, and/or amended by the Administrator, without prior notice, at the Administrator’s sole discretion. Until changed by the Administrator: (i) Measurement Fund allocation designations must be made in whole percentage points of 1%, or multiples thereof, not to exceed 100%; (ii) a Participant may change his or her Measurement Fund allocation elections on a daily basis, and (iii) a change in Measurement Fund allocations will take effect on the next business day following the election. Notice of any change in Measurement Fund elections must be made to the Administrator, or its designee, in a form acceptable to it as determined by it in its sole discretion. If a Participant fails to designate a Measurement Fund with respect to all or a portion of his or her Account Balance, such amounts shall be deemed invested in the default Measurement Fund (or Funds) designated by the Administrator, which may be changed by the Administrator from time to time without notice to Participants.

(b)Measurement Funds. A Participant may elect one or more measurement funds (the “Measurement Funds”) from among those selected by the Administrator for the purpose of crediting or debiting additional amounts to his or her Account Balance. As necessary, the Administrator may, in its sole discretion, discontinue, substitute or add Measurement Funds. In selecting the Measurement Funds that are available from time to time, neither the Administrator nor any Employer shall be liable to any Participant for such selection or adding, deleting or continuing any available Measurement Fund.

(c)Crediting or Debiting Method. The performance of each elected Measurement Fund (either positive or negative) will be determined by the Administrator, in its sole discretion, based on the performance of the Measurement Funds themselves. A Participant's Account Balance shall be credited or debited on a daily basis based on the performance of each Measurement Fund selected by the Participant, as determined by the Administrator in its sole discretion, as though (i) a Participant's Account Balance as of the close of business on each date were invested in the Measurement Fund(s) selected by the Participant, in the percentages applicable to such date, at the closing price on such date; (ii) the portion of the Deferral Amount (or Employer Contribution), if any, that was actually deferred on that date were invested in the Measurement Fund(s) selected by the Participant, in the percentages applicable to such date; and (iii) any distribution made to a Participant on that date ceased being invested in the Measurement Fund(s), in the percentages applicable to such date, at the closing price on such date.

(d)    No Actual Investment. Notwithstanding any other provision in this Plan, the Measurement Funds are to be used for measurement purposes only, and a Participant's election of any such Measurement Fund, the allocation to his or her Account Balance thereto, the calculation of additional amounts and the crediting or debiting of such amounts to a Participant's Account Balance shall not be considered or construed in any manner as an actual investment of his or her Account Balance in any such Measurement

Fund. In the event that the Company or the Trustee (as that term is defined in the Trust), in its own discretion, decides to invest funds in any or all of the Measurement Funds, no Participant shall have any rights in or to such investments themselves. Without limiting the foregoing, a Participant's Account Balance shall at all times be a bookkeeping entry only and shall not represent any investment made on his or her behalf by the Company or the Trust; the Participant shall at all times remain an unsecured creditor of the Company.

(e)    Equity Pay. Notwithstanding any other provision in this Plan and except as otherwise determined by the Administrator, to the extent a Participant elects to defer Equity Pay, such portion of the Deferral Amount shall be tracked in common stock of the Parent. Except as otherwise determined by the Administrator, adjustments or substitutions to such shares of common stock shall be made consistent with adjustments or substitutions that are applied under the equity plan pursuant to which the Equity Pay award was originally granted. The Administrator may limit (or prohibit) any change in allocation to or from such Parent stock and may establish rules applicable to accounting for, crediting, or allocating any dividends payable on such Parent stock.

3.6    FICA and Other Taxes. For each Plan Year (or other deferral period) in which a Deferral Amount is being withheld from a Participant, the Participant’s Employer(s) may withhold from that portion of the Participant’s compensation that is not being deferred, in a manner and amount determined by the Employer(s), the Participant’s share of FICA, employment taxes, and other taxes on such Deferral Amount. If the amount of Base Annual Salary and Bonus that is not being deferred is insufficient to cover these amounts, the Committee may reduce the Deferral Amount or withhold from other payments made to the Participant in order to comply with this Section. The Participant’s Employer may withhold from or offset against any Plan accrual or Account Balance any taxes the Company determines it is required to withhold by applicable federal state, local, or foreign laws.

3.7    Distributions. The Participant’s Employer(s), or the trustee of the Trust, shall withhold from any payments made to a Participant under this Plan all federal, state and local income, employment and other taxes (domestic or foreign) required to be withheld by the Employer(s), or the trustee of the Trust, in connection with such payments, in amounts and in a manner to be determined in the sole discretion of the Employer(s) and the trustee of the Trust, as applicable.

(a)    if a three year Short-Term Payout is elected for Deferral Amounts that are deferred in the Plan Year commencing January 1, 2025, the three year Short-Term Payout would be paid on January 15, 2029.

(b)    if a three year Short-Term Payout is elected for Deferral Amounts that are Equity Pay and that would otherwise be payable over a four-year graded vesting schedule (25% per year) from 2023 through 2026, the three year Short-Term Payout would be paid on January 15, 2030.

To the extent permitted by the Committee and on the Election Form, a Participant may elect more than one Short-Term Payout date with respect to different percentages or dollar amounts (if applicable) of the Deferral Amount or Employer Contribution. Except as otherwise provided on the Election Form, with respect to an election to receive Equity Pay as a Short-Term Deferral, the number of shares treated as the Short-Term Deferral shall be rounded down to the next highest whole number of shares.

4.2    Other Benefits Take Precedence Over Short-Term Payout. Should an event occur that triggers a benefit under Article 5, 6 or 7, any Deferral Amount or Employer Contribution, plus amounts credited or debited thereon, that is subject to a Short-Term Payout election under Section 4.1 shall not be paid in accordance with Section 4.1 but shall be paid in accordance with the other applicable Article.

4.3Unforeseeable Financial Emergencies. If the Participant experiences an Unforeseeable Financial Emergency the Participant may petition the Administrator to (i) cancel any deferrals required to be made by a Participant and, if such cancellation is insufficient to satisfy the Unforeseeable Financial Emergency, (ii) receive a partial or full payout from the Plan. The payout shall not exceed the lesser of the Participant's vested Account Balance, calculated as if such Participant were receiving a Termination Benefit, or the amount reasonably necessary to satisfy the Unforeseeable Financial Emergency plus amounts necessary to pay taxes reasonably anticipated as a result of the distribution, after taking into account the extent to which such hardship is or may be relieved through reimbursement or compensation by insurance or otherwise or by liquidation of the participant’s assets (to the extent the liquidation of such assets would not itself cause severe financial hardship). If the Administrator determines that an Unforeseeable Financial Emergency exists, cancellation shall take effect upon the date of such determination, and any payout shall be made thirty (30) days after such date. The payment of any amount under this Section 4.3 shall not be subject to the Deduction Limitation and any partial payout shall be deducted from a Participant’s existing Account Balance on a pro rata basis.

5.1Retirement Benefit. Subject to the Deduction Limitation, a Participant who Retires shall receive, as a Retirement Benefit, his or her vested Account Balance.

5.2Payment of Retirement Benefit. A Participant, in connection with his or her annual (or otherwise applicable) deferral election, shall elect on an Election Form to receive the Retirement Benefit attributable to the election in a lump sum or pursuant to an Annual Installment Method of up to 15 years, to the extent permitted by the Committee. To the extent permitted by the Committee and on an Election Form, a Participant may choose different forms of payment for Deferral Amounts attributable to different Plan Years (or the applicable deferral period), for different portions of Deferral Amounts (such as Equity Pay), and/or for Employer Contributions. After the Deferral Election is irrevocable, the Participant may make an election to change an existing payment election to an allowable alternative payout period by submitting a new Election Form to the Administrator, provided that any such Election Form is submitted at least one (1) year prior to the Participant's Retirement and delays the Participant’s initial payment by a period of at least five (5) years. For purposes of such election changes, the right to a series of installment payments shall be treated as the right to a single payment. If a Participant does not make any election with respect to the payment of a Deferral Amount or Employer Contribution (or, in either case, a portion thereof), then such amount shall be payable in a lump sum. Except as otherwise provided pursuant to a subsequent deferral election described above, the lump sum payment shall be made, or installment payments shall commence thirty (30) days after the date which is six (6) months after the Participant’s Retirement. Any payment made shall be subject to the Deduction Limitation.

5.3Death Prior to Completion of Retirement Benefit. If a Participant dies after Retirement but before the Retirement Benefit is paid in full, the Participant's unpaid Retirement Benefit payments shall be paid to the Participant's Beneficiary in a single lump sum as soon as practicable after the Participant’s death.

6.1Pre-Retirement Survivor Benefit. Subject to the Deduction Limitation, the Participant's Beneficiary shall receive a Pre-Retirement Survivor Benefit equal to the Participant's vested Account Balance if the Participant dies while in the employ of any Employer.

6.2Payment of Pre-Retirement Survivor Benefit. A Participant, in connection with his or her annual (or otherwise applicable) deferral election, shall elect on an Election Form whether the Pre-Retirement Survivor Benefit attributable to the election shall be received by his or her Beneficiary in a lump sum or pursuant to an Annual Installment Method of up to 15 years. The form of payment for the Pre-Retirement Survivor Benefit does not have to match the form of payment for the Retirement Benefit. To the extent permitted by the Committee and on an Election Form, a Participant may choose different forms of payment for Deferral Amounts attributable to different Plan Years (or the applicable deferral period), for different portions of Deferral Amounts (such as Equity Pay), or for Employer Contributions. After the Deferral Election is irrevocable, the Participant may make an election to change an existing payment election to an allowable

alternative payout period by submitting a new Election Form to the Committee, provided that any such Election Form is submitted at least one (1) year prior to the Participant’s death and does not accelerate the initial payment date. For purposes of such election changes, the right to a series of installment payments shall be treated as the right to a single payment. If a Participant does not make any election with respect to the payment of a Deferral Amount or Employer Contribution (or, in either case, a portion thereof), then such amount shall be paid in a lump sum. The lump sum payment shall be made, or installment payments shall commence, thirty (30) days after the date of the Participant's death. Any payment made shall be subject to the Deduction Limitation.

7.1Termination Benefit. Subject to the Deduction Limitation, the Participant shall receive a Termination Benefit, which shall be equal to the Participant's vested Account Balance if a Participant experiences a Termination of Employment prior to his or her Retirement or death.

7.2Payment of Termination Benefit. The Participant’s Termination Benefit shall be paid in a lump sum. The lump sum payment shall be made thirty days after the date which is six (6) months after the date the Participant experiences the Termination of Employment. Any payment made shall be subject to the Deduction Limitation.

8.1    Beneficiary. Each Participant shall have the right, at any time, to designate his or her Beneficiary(ies) (both primary as well as contingent) to receive any benefits payable under the Plan to a beneficiary upon the death of a Participant. The Beneficiary designated under this Plan may be the same as or different from the Beneficiary designation under any other plan of an Employer in which the Participant participates.

8.2    Beneficiary Designation; Change; Spousal Consent. A Participant shall designate his or her Beneficiary or Beneficiaries by completing and executing the Beneficiary Designation Form, and submitting it to the Administrator or its designated agent. A Participant shall have the right to change a Beneficiary by completing, signing and otherwise complying with the terms of the Beneficiary Designation Form and the Administrator's rules and procedures, as in effect from time to time. Upon the acceptance by the Administrator of a new Beneficiary Designation Form, all Beneficiary designations previously filed shall be canceled. The Administrator shall be entitled to rely on the last Beneficiary Designation Form filed by the Participant and accepted by the Administrator prior to his or her death.

8.3    Acknowledgment. No designation or change in designation of a Beneficiary shall be effective until received and acknowledged in writing by the Administrator or its designated agent.

8.4    No Beneficiary Designation. If a Participant fails to designate a Beneficiary as provided in Sections 8.1, 8.2 and 8.3 above or if all designated Beneficiaries predecease the Participant or die prior to complete distribution of the Participant's benefits, then the Participant's Beneficiary shall be deemed to be the Participant’s estate.

8.5    Doubt as to Beneficiary. If the Administrator has any doubt as to the proper Beneficiary to receive payments pursuant to this Plan, the Administrator shall have the right, exercisable in its discretion, to cause the Participant's Employer to withhold such payments until this matter is resolved to the Administrator’s satisfaction.

8.6    Discharge of Obligations. The payment of benefits under the Plan to a Beneficiary shall fully and completely discharge all Employers and the Administrator from all further obligations under this Plan with respect to the Participant, and that Participant's participation shall terminate upon such full payment of benefits.

9.1    Paid Leave of Absence. If a Participant is authorized by the Participant's Employer for any reason to take a paid leave of absence from the employment of the Employer, the Participant shall continue to be considered employed by the Employer and the Deferral Amount shall continue to be withheld during such paid leave of absence in accordance with Section 3.2.

9.2    Unpaid Leave of Absence. If a Participant is authorized by the Participant's Employer for any reason to take an unpaid leave of absence from the employment of the Employer, deferrals of the Participant’s Base Annual Salary shall automatically cease during such period because the leave of absence is unpaid. However, the Participant’s deferral election shall remain in effect with respect to Annual Bonus and Equity Pay paid during such period. Upon the Participant’s return to paid employment status, deferrals of the Participant’s Base Annual Salary shall resume for the remaining portion of the Plan Year in which the return occurs, based on the deferral election, if any, made for that Plan Year. If no election was made for that Plan Year, no deferral shall be withheld.

9.3    Leave of Absence Treated as a Termination of Employment. Notwithstanding the provisions of Sections 9.1 and 9.2, to the extent required by Code section 409A and IRS guidance thereunder, a leave of absence, whether paid or unpaid, shall be treated as a Termination of Employment (or Retirement, to the extent the Participant is eligible to Retire), and payments shall commence as set forth in Articles 4-7. However, the Participant’s deferral election shall remain in effect unless and until the Participant receives a lump sum payment of his or entire vested Account Balance.

9.4    Reemployment following Retirement or Termination of Employment. If a Participant Retires or has a Termination of Employment and subsequently becomes an Employee, payment of benefits accrued during the Participant’s earlier period of service shall continue to be made as if the Participant had remained Retired or Terminated. However, to the extent permitted by the other provisions of this Plan, the Participant may accrue additional benefits under the Plan with respect to the subsequent period of service and may make new elections with respect to the timing and form of payment of such amounts.

10.1    Termination. Although it is anticipated that the Plan will continue for an indefinite period of time, there is no guarantee that the Company will continue the Plan. Accordingly, the Company reserves the right to discontinue its sponsorship of the Plan and/or to terminate the Plan at any time with respect to any Employer by action of the Board or the Board of Directors of the Parent. In general, upon the termination of the Plan with respect to any Employer, the affected Participants who are employed by that Employer shall receive payment of their benefits in accordance with the terms of Articles 4-7. However, the Company may, in its discretion, terminate the Plan, in whole or in part, and pay each Participant a single lump-sum distribution of his or her entire Account Balance, to the extent consistent with Section 15.20.

10.2    Amendment. The Company may, at any time, amend or modify the Plan, in whole or in part, with respect to any or all Employers; provided, however, that: (i) no amendment or modification shall be effective to decrease or restrict the value of a Participant's Account Balance in existence at the time the amendment or modification is made, calculated as if the Participant had experienced a Termination of Employment as of the effective date of the amendment or modification or, if the amendment or modification occurs after the date upon which the Participant was eligible to Retire, the Participant had Retired as of the effective date of the amendment or modification, and (ii) no amendment or modification to clause (i) of this Section 10.2 or of Section 11.2 of the Plan shall be effective.

Such amendment may be adopted by: (a)    the Board or the Board of Directors of the Parent, acting on behalf of the Company; (b) the Human Resource and Compensation Committee appointed by the Board of Directors of the Parent, acting on behalf of the Company, provided that no such amendment may increase or decrease the aggregate cost to the Company and any other participating employers of maintaining the Plan by more than $25 million on an annual basis; or (c) the Chief Financial Officer of the Parent, acting on behalf of the Company, or the Chief Human Resources Officer of Jacobs Engineering Group Inc., provided that such amendment either (i) consists of changes that are reasonably necessary or desirable to comply with applicable law, or (ii) does not increase or decrease the aggregate cost to the Company Sand any other participating employers of maintaining the Plan by more than $5 million on an annual basis.

10.3    Plan Agreement. The terms of any Plan agreement between the Employee and Company or Employer may be different for any Participant, and a Plan agreement may provide additional benefits not set forth in the Plan or limit the benefits otherwise provided under the Plan; provided, however, that any such additional benefits or benefit limitations must be agreed to by both the Employer and the Participant. Despite the provisions of Sections 10.1 and 10.2 above, if a Participant's Plan agreement contains benefits or limitations that are not in this Plan document, the Employer may only amend or terminate such provisions with the consent of the Participant.

10.4    Effect of Payment. The full payment of the applicable benefit under Articles 4, 5, 6 or 7 of the Plan shall completely discharge all obligations to a Participant and his or her designated Beneficiaries under this Plan and the Participant's Plan participation shall terminate.

10.5    Divestitures. Certain Participants may terminate their employment with the Company as part of the sale or spin-off of part of the Company’s business operations, or of one or more of the Company’s subsidiaries or affiliates, to another company. As part of these transactions, a

Participant’s benefits under the Plan, including the Employer’s liability for payment thereof, may be transferred to a plan of the acquiring company. All rights of any such Participant and his or her Beneficiary(ies) under the Plan or Trust, and any liabilities of the Plan, Trust, Company or Employer, terminate effective upon such a transfer of benefits and liabilities.

11.1    Committee Duties. Except as otherwise provided in this Article 11, this Plan shall be administered by the Committee. The Committee shall also have the discretion and authority to (i) make, amend, interpret, and enforce all appropriate rules and regulations for the administration of this Plan and (ii) decide or resolve any and all questions including interpretations of this Plan, as may arise in connection with the Plan. Any individual serving on the Committee who is a Participant shall not vote or act on any matter relating solely to himself or herself. When making a determination or calculation, the Committee shall be entitled to rely on information furnished by a Participant or the Company.

11.2    Administration Upon Change in Control. For purposes of this Plan, the Company (via the Committee described in Section 11.1) shall be the “Administrator” at all times prior to the occurrence of a Change in Control. Upon and after the occurrence of a Change in Control, the “Administrator” shall be an independent third party selected by the Trustee and approved by the individual who, immediately prior to such event, was the Company’s Chief Executive Officer or, if not so identified, the Company’s highest ranking officer (the “Ex-CEO”). The Administrator shall have the discretionary power to determine all questions arising in connection with the administration of the Plan and the interpretation of the Plan and Trust including, but not limited to benefit entitlement determinations; provided, however, upon and after the occurrence of a Change in Control, the Administrator shall have no power to direct the investment of Plan or Trust assets or select any investment manager or custodial firm for the Plan or Trust. Upon and after the occurrence of a Change in Control, the Company must: (1) pay all reasonable administrative expenses and fees of the Administrator; (2) indemnify the Administrator against any costs, expenses and liabilities including, without limitation, attorney’s fees and expenses arising in connection with the performance of the Administrator hereunder, except with respect to matters resulting from the gross negligence or willful misconduct of the Administrator or its employees or agents; and (3) supply full and timely information to the Administrator or all matters relating to the Plan, the Trust, the Participants and their Beneficiaries, the Account Balances of the Participants, the date of circumstances of the Retirement, death or Termination of Employment of the Participants, and such other pertinent information as the Administrator may reasonably require. Upon and after a Change in Control, the Administrator may be terminated (and a replacement appointed) by the Trustee only with the approval of the Ex-CEO. Upon and after a Change in Control, the Administrator may not be terminated by the Company.

11.3    Agents. In the administration of this Plan, the Administrator may, from time to time, delegate to employees of an Employer or other agents it employs such administrative duties as it sees fit (including acting through a duly appointed representative) and may from time to time consult with counsel who may be counsel to any Employer.

11.4    Binding Effect of Decisions. The decision or action of the Administrator with respect to any question arising out of or in connection with the administration, interpretation and application of the Plan and the rules and regulations promulgated hereunder shall be final and conclusive and binding upon all persons having any interest in the Plan.

11.5    Indemnity of Administrator. All Employers shall indemnify and hold harmless the members of the Committee, any employee to whom the duties of the Committee may be delegated, and the Administrator against any and all claims, losses, damages, expenses or liabilities arising from any action or failure to act with respect to this Plan, except in the case of willful misconduct by the Committee, any of its members, any such employee or the Administrator.

11.6    Missing Payees. If the Administrator cannot locate any person or estate entitled to payment of a Plan benefit after a reasonable search, the Administrator may at any time thereafter treat such benefit as forfeited. If the person or estate should later make a valid claim for the benefit or otherwise be located, any amounts so forfeited shall be reinstated (without any interest or earnings adjustment) and paid to the person or estate, as otherwise provided by this Plan, unless the benefit has been escheated to a state government.

11.7    Payment Delay or Acceleration. Notwithstanding any other provision in this Plan, the Administrator may, in its sole and absolute discretion, delay or accelerate payments under the Plan to the extent consistent with Section 15.20.

12.1    Coordination with Other Benefits. The benefits provided for a Participant and Participant's Beneficiary under the Plan are in addition to any other benefits available to such Participant under any other plan or program for employees of the Participant's Employer. The Plan shall supplement and shall not supersede, modify or amend any other such plan or program except as may otherwise be expressly provided.

13.1    Presentation of Claim. Any Participant or Beneficiary of a deceased Participant (such Participant or Beneficiary being referred to below as a "Claimant") may deliver to the Administrator a written claim for a determination with respect to the amounts distributable to such Claimant from the Plan. If such a claim relates to the contents of a notice received by the Claimant, the claim must be made within 60 days after such notice was received by the Claimant. All other claims must be made within 180 days of the date on which the event that caused the claim to arise occurred. The claim must state with particularity the determination desired by the Claimant.

13.2    Notification of Decision. The Administrator shall consider a Claimant's claim within a reasonable time, and shall notify the Claimant in writing:

(a)    that the Claimant's requested determination has been made, and that the claim has been allowed in full; or

(b)    that the Administrator has reached a conclusion contrary, in whole or in part, to the Claimant's requested determination, and such notice must set forth in a manner calculated to be understood by the Claimant:

(i)    the specific reason(s) for the denial of the claim, or any part of it;

(ii)    specific reference(s) to pertinent provisions of the Plan upon which such denial was based;

(iii)    a description of any additional material or information necessary for the Claimant to perfect the claim, and an explanation of why such material or information is necessary; and

(iv)    an explanation of the claim review procedure set forth in Section 13.3 below.

13.3    Review of a Denied Claim. Within 60 days after receiving a notice from the Administrator that a claim has been denied, in whole or in part, a Claimant (or the Claimant's duly authorized representative) may file with the Administrator a written request for a review of the denial of the claim. In conjunction with filing an appeal (but no later than the date the appeal is filed), the Claimant (or the Claimant's duly authorized representative):

(a)    may review pertinent documents;

(b)    may submit written comments or other documents; and/or

(c)    may request a hearing, which the Administrator, in its sole discretion, may grant.

13.4    Decision on Review. The Administrator shall render its decision on review promptly, and not later than 60 days after the filing of a written request for review of the denial, unless a hearing is held or other special circumstances require additional time, in which case the Administrator's decision must be rendered within 120 days after such date. Such decision must be written in a manner calculated to be understood by the Claimant, and it must contain:

(a)    specific reasons for the decision;

(b)    specific reference(s) to the pertinent Plan provisions upon which the decision was based; and

(c)    such other matters as the Administrator deems relevant.

13.5    Legal Action. A Claimant's compliance with the foregoing provisions of this Article 13 is a mandatory prerequisite to a Claimant's right to commence any legal action with respect to any claim for benefits under this Plan.

13.6    Payment Following Resolution of Claim. If a Participant is entitled to a payment following the resolution of a claim pursuant to this Article 13, such payment will be made during the calendar year in which the claim is finally and conclusively resolved, or, if later, at the time set forth under Articles 4-7.

14.1    Establishment of the Trust. The Company has established the Trust, and each Employer shall at least annually transfer over to the Trust such assets as the Employer determines, in its sole discretion, are necessary to provide, on a present value basis, for its respective future liabilities created with respect to the Deferral Amounts and Employer Contributions for such Employer's Participants for all periods prior to the transfer, as well as any debits and credits to the Participants' Account Balances for all periods prior to the transfer, taking into consideration the value of the assets in the trust at the time of the transfer.

14.2    Interrelationship of the Plan and the Trust. The provisions of the Plan shall govern the rights of a Participant to receive distributions pursuant to the Plan. The provisions of the Trust shall govern the rights of the Employers, Participants and the creditors of the Employers to the assets transferred to the Trust. Each Employer shall at all times remain liable to carry out its obligations under the Plan.

14.3    Distributions From the Trust. Each Employer's obligations under the Plan may be satisfied with Trust assets distributed pursuant to the terms of the Trust, and any such distribution shall reduce the Employer's obligations under this Plan.

14.4    Investment of Trust Assets. The Trustee of the Trust shall be authorized, upon written instructions received from the Administrator or investment manager appointed by the Administrator, to invest and reinvest the assets of the Trust in accordance with the applicable Trust Agreement, including the disposition of stock and reinvestment of the proceeds in one or more investment vehicles designated by the Administrator.

15.1    Status of Plan. The Plan is not intended to qualify under Code Section 401(a). The Plan “is unfunded and is maintained by an employer primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees” within the meaning of ERISA Sections 201(2), 301(a)(3) and 401(a)(1). The Plan shall be administered and interpreted to the extent possible in a manner consistent with that intention.

15.2    Unsecured General Creditor. Participants and their Beneficiaries, heirs, successors and assigns shall have no legal or equitable rights, interests or claims in any property or assets of any Employer, including any assets held in the Trust. For purposes of the payment of benefits under this Plan, any and all of an Employer's assets shall be, and remain, the general, unpledged unrestricted assets of the Employer. An Employer's obligation under the Plan shall be merely that of an unfunded and unsecured promise to pay money in the future.

15.3    Employer's Liability. An Employer's liability for the payment of benefits shall be defined only by the Plan and any Plan agreement entered into between the Employer and a Participant. An Employer shall have no obligation to a Participant under the Plan except as expressly provided in the Plan.

15.4    Nonassignability. Neither a Participant nor any other person shall have any right to commute, sell, assign, transfer, pledge, anticipate, mortgage or otherwise encumber, transfer, hypothecate, alienate or convey in advance of actual receipt, the amounts, if any, payable hereunder, or any part thereof, which are, and all rights to which are expressly declared to be, unassignable and

non-transferable. No part of the amounts payable shall, prior to actual payment, be subject to seizure, attachment, garnishment or sequestration for the payment of any debts, judgments, alimony or separate maintenance owed by a Participant or any other person or be transferable by operation of law in the event of a Participant's or any other person's bankruptcy or insolvency.

15.5    Not a Contract of Employment. The terms and conditions of this Plan shall not be deemed to constitute a contract of employment or retention between any Employer (or any of its Affiliates) and the Participant. Such employment is hereby acknowledged to be an "at will" employment relationship that can be terminated at any time for any reason, or no reason, with or without cause, and with or without notice, unless expressly provided in a written employment agreement. Nothing in this Plan shall be deemed to give a Participant the right to be retained in the service of any Employer (or any of its Affiliates), either as an employee or otherwise, or to interfere with the right to discipline or discharge the Participant at any time.

15.6    Furnishing Information. A Participant or his or her Beneficiary will cooperate with the Administrator by furnishing any and all information requested by the Administrator and take such other actions as may be requested in order to facilitate the administration of the Plan and the payments of benefits hereunder, including but not limited to taking such physical examinations as the Administrator may deem necessary.

15.7    Terms. Whenever any words are used herein in the masculine, they shall be construed as though they were in the feminine in all cases where they would so apply; and whenever any words are used herein in the singular or in the plural, they shall be construed as though they were used in the plural or the singular, as the case may be, in all cases where they would so apply.

15.8    Captions. The captions of the articles, sections and paragraphs of this Plan are for convenience only and shall not control or affect the meaning or construction of any of its provisions.

15.9    Governing Law. Subject to ERISA, the provisions of this Plan shall be construed and interpreted according to the internal laws of the State of Texas without regard to its conflicts of laws principles.

15.10    Notice. Any notice or filing required or permitted to be given to the Committee under this Plan shall be sufficient if in writing and hand-delivered, or sent by registered or certified mail, to the address below:

Such notice shall be deemed given as of the date of delivery or, if delivery is made by mail, as of the date shown on the postmark on the receipt for registration or certification.

Any notice or filing required or permitted to be given to a Participant under this Plan shall be sufficient if in writing and hand-delivered, or sent by mail, to the last known address of the Participant.

15.11    Successors. The provisions of this Plan shall bind and inure to the benefit of the Participant's Employer and its successors and assigns and the Participant and the Participant's designated Beneficiaries.

15.12    Spouse's Interest. The interest in the benefits hereunder of a spouse of a Participant who has predeceased the Participant shall automatically pass to the Participant and shall not be transferable by such spouse in any manner, including but not limited to such spouse's will, nor shall such interest pass under the laws of intestate succession.

15.13    Validity. In case any provision of this Plan shall be illegal or invalid for any reason, said illegality or invalidity shall not affect the remaining parts hereof, but this Plan shall be construed and enforced as if such illegal or invalid provision had never been inserted herein.

15.14    Incompetent. If the Administrator determines in its discretion that a benefit under this Plan is to be paid to a minor, a person declared incompetent or to a person incapable of handling the disposition of that person's property, the Administrator may direct payment of such benefit to the guardian, legal representative or person having the care and custody of such minor, incompetent or incapable person. The Administrator may require proof of minority, incompetence, incapacity or guardianship, as it may deem appropriate prior to distribution of the benefit. Any payment of a benefit shall be a payment for the account of the Participant and the Participant's Beneficiary, as the case may be, and shall be a complete discharge of any liability under the Plan for such payment amount.

15.15    Payments to Spouses. The Plan will not honor domestic relations orders, except as determined by the Administrator.

15.16    Distribution in the Event of Taxation.

(a)    In General. If, for any reason, all or any portion of a Participant's benefits under this Plan becomes taxable to the Participant under Code section 409A prior to receipt, an amount equal to the taxable portion of his or her benefit will be distributed immediately to the Participant in the form of a lump sum (which amount shall not exceed the Participant's unpaid vested Account Balance under the Plan). Such a distribution shall affect and reduce the benefits to be paid under this Plan.

(b)    Trust. If the Trust terminates in accordance with Section 4.6(d) of the Trust and benefits are distributed from the Trust to a Participant in accordance with that Section, the Participant's benefits under this Plan shall be reduced to the extent of such distributions.

15.17    Payment Delays due to Employer Insolvency. Notwithstanding any other provision in this Plan, payment of a Participant’s benefits will be delayed in the event that making the payment will jeopardize the ability of the Employer to continue as a going concern. A payment delayed pursuant to this Section 15.17 will be made during the first calendar year in which making the payment would not have such effect.

15.18    Insurance. The Employers, on their own behalf or on behalf of the trustee of the Trust, and, in their sole discretion, may apply for and procure insurance on the life of the Participant, in such amounts and in such forms as the Employers may choose. The Employers or the trustee of the Trust, as the case may be, shall be the sole owner and beneficiary of any such insurance. The Participant shall have no interest whatsoever in any such policy or policies, and at the request of the Employers shall submit to medical examinations and supply such information and execute such documents as may be required by the insurance company or companies to whom the Employers have applied for insurance.

15.19    Legal Fees to Enforce Rights After Change in Control. The Company and each Employer is aware that upon the occurrence of a Change in Control, the Board or the board of directors of a Participant’s Employer (which might then be composed of new members) or a shareholder of the Company or the Participant’s Employer, or of any successor corporation, or the Administrator or the Committee, might then cause or attempt to cause the Company, the Participant’s Employer or such successor to refuse to comply with its obligations under the Plan and might cause or attempt to cause the Company or the Participant’s Employer to institute, or may institute, litigation seeking to deny Participants the benefits intended under the Plan. In these circumstances, the purpose of the Plan could be frustrated. Accordingly, if, following a Change in Control, it should appear to any Participant that the Company, the Participant’s Employer or any successor corporation, or the Administrator or any member of the Committee, has failed to comply with any of its obligations under the Plan or any agreement thereunder or, if the Company, such Employer or any other person takes any action to declare the Plan void or unenforceable or institutes any litigation or other legal action designed to deny, diminish or to recover from any Participant the benefits intended to be provided, then the Company and the Participant’s Employer irrevocably authorize such Participant to retain counsel of his or her choice at the expense of the Company and the Participant’s Employer (who shall be jointly and severally liable) to represent such Participant in connection with the initiation or defense of any litigation or other legal action, whether by or against the Company, the Participant’s Employer or any director, officer, shareholder or other person affiliated with the Company, the Participant’s Employer or any successor thereto in any jurisdiction. In order to be eligible for counsel at the expense of the Company or successor (or reimbursement of counsel fees to the extent the Company or successor initially refuses to pay such expenses) pursuant to this Section 15.19, fees and expenses must be incurred on or after a Change in Control and before the later of (i) the closing of the Participant’s estate, and (ii) the closing of the estate of each Beneficiary. Any payment made on behalf of a Participant or to which a Participant is entitled pursuant to this Section must be made no later than the last day of the Participant’s taxable year following the taxable year in which the related fee or expense is incurred.

15.20    Code Section 409A. The Plan is intended to avoid any “plan failures” within the meaning of Code section 409A(a)(1). The Plan shall be interpreted and administered, to the extent possible, in accordance with this intention.

Notwithstanding any other provision of the Plan to the contrary, effective August 1, 2021 (the “Effective Date”), Employees in a Domestic Partnership with a Domestic Partner will be entitled to the same Plan benefits available to Employees married to a Spouse, except to the extent that the extension of such benefit with respect to a Domestic Partner is prohibited by the Internal Revenue Code or ERISA, would result in the imposition of additional taxation, or would otherwise increase the risk of non-compliance with the Code, ERISA, or other applicable law. This Addendum is intended to comply with, and shall be interpreted in a manner that is consistent with, the requirements of Chapter 12B of the San Francisco Administrative Code.

For these purposes:

(a)    “Domestic Partner” means the person, other than a Spouse, with whom the Employee or Participant is either (i) registered as a couple with any government body pursuant to state or local law authorized to perform such registrations, or (ii) substantiated as a couple in accordance with requirements and criteria determined by the Plan Administrator including, for example, use of a notarized affidavit in a form approved by the Plan Administrator.

(b)    “Domestic Partnership” means the relationship between the Employee or Participant and their Domestic Partner. Any requirements for proof of relationship for Domestic Partnerships will be comparable to those for marriage.

In illustration of the foregoing:

(1)Where the Plan requires Spousal consent with respect to an Employee who is married, the Plan also requires Domestic Partner consent with respect to an Employee who is in a Domestic Partnership.

(2)Where the Plan provides that a married Employee’s Spouse would be the default beneficiary (for example, if the Employee dies without a valid beneficiary on file), the Plan similarly will provide that an Employee’s Domestic Partner would be the default beneficiary.

(3)Where the Plan recognizes an Employee’s divorce from their Spouse, the Plan similarly will recognize the termination of an Employee’s Domestic Partnership – for example, in canceling the Employee’s beneficiary designation – but not with respect to recognizing a domestic relations order, which is limited to spouses under applicable Code and ERISA rules.

(4)Consistent with Treas. Reg. Sec. 1.409A-3(i)(3)(i), unforeseeable emergency withdrawals triggered by an illness or accident of the Domestic Partner, or similar event, will be limited to situations where the Domestic Partner is a tax dependent.

(5)Consistent with the foregoing examples, references to spouse in the Plan document will mean spouse or domestic partner, as applicable.
