“COMPENSATION” shall mean the compensation paid to a Participant by the Employer for the Plan Year and shall be defined as the base compensation paid to a Participant by the Employer for the Plan Year, exclusive of any amounts deferred under any other program of deferred compensation, any additional benefit payable other than in cash and any compensation received prior to his becoming a Participant in the Plan. Compensation shall, however, include any amounts deferred under a salary reduction agreement in accordance with Section 4.1 or under a Code Section 125 Plan maintained by the Employer. Notwithstanding the foregoing (a) for purposes of Section 4.1, such Participant may elect to have his Compensation be based on total pay, including overtime, standby pay, shift differentials, Saturday-Sunday premiums, lump sum merits, meal allowances and meal periods, compensation paid at an alternative rate, bonuses, commissions and incentive payments, and (b) Compensation for purposes of Section 4.2 shall include bonuses and incentive payments, but exclude overtime pay, commissions, and all other forms of premium pay.

“DISABILITY” shall mean a “permanent and total” disability incurred by a Participant while in the employ of the Employer. For this purpose, a Participant shall be deemed “Disabled” if he is entitled to receive disability benefits under Social Security and/or he is determined by the carrier of the Employer’s long-term disability plan to be entitled to benefits under the Employer’s long-term disability plan.

“EFFECTIVE DATE.” The Plan’s initial Effective Date was January 1, 1985. The Effective Date of this restated Plan, on and after which it supersedes the terms of the existing Plan document, is January 1, 2021, except where the provisions of the Plan (or the requirements of applicable law) shall otherwise specifically provide. The rights of any Participant who terminated employment with the Employer prior to the applicable date shall be established under the terms of the Plan and Trust as in effect at the time of the Participant’s termination from employment, unless the Participant subsequently returns to employment with the Employer, or unless otherwise provided under the terms of the Plan. Rights of spouses and Beneficiaries of such Participants shall also be governed by those documents.

“EMPLOYEE” shall mean a common law employee of the Employer. The term “Employee” shall also include any employee of an employer that is aggregated with the Employer under Section 414(b), (c), (m) or (o) of the Code and any Leased Employee deemed to be an Employee of the Employer as provided in Section 414(n) or 414(o) of the Code. Notwithstanding the foregoing, only Employees of an Employer who has adopted the Plan in accordance with Section 1.10 of the Plan shall be eligible to participate in the Plan upon satisfaction of the eligibility requirements of Article Three of the Plan.

“EMPLOYER” shall mean Unitil Corporation (the “Company”) and any subsidiary or affiliate which is a member of its “related group” (as defined in Section 2.5) which has adopted the Plan (a “Participating Affiliate”), and shall include any successor(s) thereto which adopt this Plan. Any such subsidiary or affiliate of the Company may adopt the Plan with the approval of its board of directors (or noncorporate counterpart) subject to the approval of the Company. The provisions of this Plan shall apply equally to each Participating Affiliate and its Employees except as specifically set forth in the Plan; provided, however, notwithstanding any other provision of this Plan, the amount and timing of contributions under Article 4 to be made by any Employer which is a Participating Affiliate may be made subject to the approval of the Company. For purposes hereof, each Participating Affiliate shall be deemed to have appointed the Company as its agent to act on its behalf in all matters relating to the administration, amendment, termination of the Plan and the investment of the assets of the Plan. For purposes of the Code and ERISA, the Plan as maintained by the Company and the Participating Affiliates shall constitute a single plan rather than a separate plan of each Participating Affiliate. All assets in the Trust shall be available to pay benefits to all Participants and their Beneficiaries.

“EMPLOYMENT DATE” shall mean the first date as of which an Employee is credited with an Hour of Service, provided that, in the case of a Break in Service, the Employment Date shall be the first date thereafter as of which an Employee is credited with an Hour of Service.

“FAIL-SAFE CONTRIBUTION” shall mean a qualified nonelective contribution which is a contribution (other than matching contributions or Qualified Matching Contributions (within the meaning of Section 10.2)) made by the Employer and allocated to Participants’ Accounts that the Participants may not elect to receive in cash until distribution from the Plan; that is nonforfeitable when allocated to Participants’ Accounts; and subject to the distribution limitations under Treasury Regulation Section 1.401(k)-1(d) of the Code.

“HIGHLY-COMPENSATED EMPLOYEE” shall mean any Employee of the Employer who:

was a five percent (5%) owner of the Employer (as defined in Section 416(i)(1) of the Code) at any time during the “determination year” or “look-back year”; or

earned compensation (as defined under Section 11.1(b)(2) of the Plan) from the Employer during the “look-back year” in excess of the amount set forth in Section 414(q)(1) of the Code, as adjusted in accordance with Section 415(d) of the Code, and was in the top twenty percent (20%) of Employees by Compensation for such year.

“HOUR OF SERVICE” shall have the meaning set forth below:

An Hour of Service is each hour for which an Employee is paid, or entitled to payment, for the performance of duties for the Employer, during the applicable computation period.

An Hour of Service is each hour for which an Employee is paid, or entitled to payment, by the Employer on account of a period of time during which no duties

No more than five hundred and one (501) Hours of Service shall be credited under this paragraph (b) to any Employee on account of any single continuous period during which the Employee performs no duties (whether or not such period occurs in a single computation period). Hours under this paragraph shall be calculated and credited pursuant to Section 2530.200b-2 of the Department of Labor Regulations which is incorporated herein by reference;

An hour for which an Employee is directly or indirectly paid, or entitled to payment, on account of a period during which no duties are performed shall not be credited to the Employee if such payment is made or due under a plan maintained solely for the purpose of complying with applicable workmen’s compensation, or unemployment compensation or disability insurance laws; and

Hours of Service shall not be credited for a payment which solely reimburses an Employee for medical or medically related expenses incurred by the Employee.

An Hour of Service is each hour for which back pay, irrespective of mitigation of damages, is either awarded or agreed to by the Employer. The same Hours of Service shall not be credited both under paragraph (a) or paragraph (b), as the case may be, and under this paragraph (c). Thus, for example, an Employee who receives a back pay award following a determination that he was paid at an unlawful rate for Hours of Service previously credited shall not be entitled to additional credit for the same Hours of Service. Crediting of Hours of Service for back pay awarded or agreed to with respect to periods described in paragraph (b) shall be subject to the limitations set forth in that paragraph.

Hours of Service under this Section shall be determined under the terms of the Family and Medical Leave Act of 1993 and the Uniformed Services Employment and Reemployment Rights Act of 1994.

“LEASED EMPLOYEE” shall mean any person (other than an employee of the recipient) who, pursuant to an agreement between the recipient Employer and any other person or organization, has performed services for the recipient Employer (determined in accordance with Section 414(n)(6) of the Code) on a substantially full-time basis for a period of at least one (1) year and where such services are performed under the primary direction or control of the recipient Employer. A person shall not be considered a Leased Employee if the total number of Leased Employees does not exceed twenty percent (20%) of the Nonhighly-Compensated Employees employed by the recipient Employer, and if any such person is covered by a money purchase pension plan providing (a) a nonintegrated employer contribution rate of at least ten percent (10%) of compensation, as defined in Section 11.1(b)(2) of the Plan but including amounts contributed pursuant to a salary reduction agreement which are excludable from the employee’s gross income under Sections 125, 402(e)(3), 402(g), 402(h)(1)(B), 403(b), or 457(b) of the Code, and shall also include elective amounts that are not includible in the gross income of the Employee by reason of Section 132(f) of the Code, (b) immediate participation, and (c) full and immediate vesting.

“LOCAL 1837 USC EMPLOYEE” shall mean an Employee of Unitil Service Corp. (“USC”) who is covered under a collective bargaining agreement between Unitil Service Corp. and the International Brotherhood of Electrical Workers, Local Union No. 1837.

“NORMAL RETIREMENT DATE” shall mean the Participant’s sixty-fifth (65^th) birthday. The date on which the Participant attains age sixty-five (65) shall also be the Participant’s Normal Retirement Age.

“PARTICIPANT” shall mean any Employee or former Employee who has satisfied the participation requirements of Article Three.

“PLAN” shall mean the Unitil Corporation Tax Deferred Savings and Investment Plan, as set forth herein and as may be amended from time to time.

If an Employee fails to be credited with at least one thousand (1,000) Hours of Service during that computation period, he shall be credited with a Year of Service for such purposes if he is credited with at least one thousand (1,000) Hours of Service in any Plan Year commencing on or after his Employment Date. For purposes of determining an Employee’s nonforfeitable right to that portion of his Account attributable to Employer contributions under the schedule set forth in Section 6.1, an Employee shall be credited with a Year of Service for each Plan Year in which he is credited with at least one thousand (1,000) Hours of Service. For eligibility purposes, an Employee shall be credited with a Year of Service upon completing the one thousandth (1,000^th) Hour of Service in the applicable twelve (12) month period. For vesting purposes, an Employee shall be credited with a Year of Service upon completion of the one thousandth (1,000^th) hour in each such twelve (12)-month period.

BREAK IN SERVICE. A Break in Service shall be a twelve (12)-month computation period (as used for measuring Years of Service for vesting purposes) in which an Employee or Participant is not credited with at least five hundred and one (501) Hours of Service.

LEAVE OF ABSENCE. A Participant on an unpaid leave of absence pursuant to the Employer’s normal personnel policies shall be credited with Hours of Service at his regularly-scheduled weekly rate while on such leave, provided the Employer acknowledges in writing that the leave is with its approval. These Hours of Service shall be credited only for purposes of determining if a Break in Service has occurred. Hours of Service during a paid leave of absence shall be credited as provided in Section 1.14.

the Hours of Service which otherwise normally would have been credited to such individual but for such absence; or

in any case where the Administrator is unable to determine the Hours of Service, on the basis of an assumed eight (8) hours per day.

RULE OF PARITY ON RETURN TO EMPLOYMENT. An Employee who returns to employment after a Break in Service shall retain credit for his pre-Break Years of Service, subject to the following rules:

If a Participant incurs five (5) or more consecutive Breaks in Service, any Years of Service performed thereafter shall not be used to increase the nonforfeitable interest in his Account accrued prior to such five (5) or more consecutive Breaks in Service.

If a Participant incurred a Break in Service when he was not vested in any portion of his Account, his pre-Break Years of Service shall be disregarded if his consecutive Breaks in Service equal or exceed five (5).

SERVICE IN EXCLUDED JOB CLASSIFICATIONS OR WITH RELATED COMPANIES

Service while a Member of an Ineligible Classification of Employees. An Employee who is a member of an ineligible classification of Employees shall not be eligible to participate in the Plan while a member of such ineligible classification. However, if any such Employee is transferred to an eligible classification, such Employee shall be credited with any Years of Service completed while a member of such an ineligible classification. For this purpose, an Employee shall be considered a member of an ineligible classification of Employees for any period during which he is employed in a job classification which is excluded from participating in the Plan under Section 3.1 below.

Service with Related Group Members. Subject to Section 2.1, for each Plan Year in which the Employer is a member of a “related group”, as hereinafter defined, all Service of an Employee or Leased Employee (hereinafter collectively referred to as “Employee” solely for purposes of this Section 2.5(b)) with any one or more members of such related group shall be treated as employment by the Employer for purposes of determining the Employee’s Years of Service. The transfer of employment by any such Employee to another member of the related group shall not be deemed to constitute a retirement or other termination of employment by the Employee for purposes of this Section, but the Employee shall be deemed to have continued in employment with the Employer for purposes of determining the Employee’s Years of Service. For purposes of this subsection (b), “related group” shall mean the Employer and all corporations, trades or businesses (whether or not incorporated) which constitute a controlled group of corporations with the Employer, a group of trades or businesses under common control with the Employer, or an affiliated service group which includes the Employer, within the meaning of Section 414(b), Section 414(c), or Section 414(m), respectively, of the Code or any other entity required to be aggregated under Code Section 414(o).

Construction. This Section is included in the Plan to comply with the Code provisions regarding the crediting of Service, and not to extend any additional rights to Employees in ineligible classifications other than as required by the Code and regulations thereunder.

PARTICIPATION. All Employees participating in the Plan prior to the Plan’s restatement shall continue to participate, subject to the terms hereof.

RE-EMPLOYMENT OF FORMER PARTICIPANT. A vested Participant (or a nonvested Participant whose prior Service cannot be disregarded) whose participation ceased because of termination of employment with the Employer shall resume participating upon his reemployment as an eligible Employee; provided, however, that such an individual (if not otherwise a member of an excluded class pursuant to Section 3.1 of the Plan) shall be entitled to commence elective deferrals (within the meaning of Section 4.1) as soon as administratively possible following his return to participation in the Plan.

TERMINATION OF ELIGIBILITY. In the event a Participant is no longer a member of an eligible class of Employees and he becomes ineligible to participate, such Employee shall resume participating upon his return to an eligible class of Employees; provided, however, that such an individual shall be entitled to commence elective deferrals (within the meaning of Section 4.1) as soon as administratively possible following his return to participation in the Plan.

COMPLIANCE WITH USERRA. Notwithstanding any provision of this Plan to the contrary, Participants shall receive service credit and be eligible to make elective deferrals (within the meaning of Section 4.1), after-tax contributions and receive Employer contributions with respect to periods of qualified military service (within the meaning of Section 414(u)(5) of the Code) in accordance with Section 414(u) of the Code.

ELECTIVE DEFERRALS

Elections. A Participant may elect to contribute a portion of his Compensation for a Plan Year on a pre-tax basis and/or in the form of designated Roth contributions. The amount of a Participant’s Compensation contributed in accordance with the Participant’s election shall be withheld by the Employer from the Participant’s Compensation on a ratable basis throughout the Plan Year. Except as otherwise provided with respect to an in-plan Roth conversion under Section 7.9, elective deferrals contributed to the Plan as one type, either as a pre-tax or a Roth contribution, may not later be reclassified as the other type. The amount deferred on behalf of each Participant shall be contributed by the Employer to the Plan and allocated to the portions of the Participant’s Account consisting of pre-tax contributions and/or Roth contributions, as the case may be. No contributions other than Roth contributions, in-plan Roth conversions, and properly attributable earnings will be credited to the Participant’s Roth account, and gains, losses and other credits or charges will be allocated on a reasonable and consistent basis to such account.

Changes in Election. A Participant may prospectively elect to change or revoke the amount (or percentage) of his elective deferrals during the Plan Year by filing a written election with the Employer, or via such other method as permitted by applicable law.

Limitations on Deferrals. Except to the extent permitted under Section 4.1(e), no Participant shall be permitted to make elective deferrals during any taxable year in excess of the dollar limitation contained in Section 402(g) of the Code in effect for such taxable year.

Administrative Rules. All elections made under this Section 4.1, including the amount and frequency of deferrals, shall be subject to the rules of the Administrator which shall be consistently applied and which may be changed from time to time.

Catch-up Contributions. All Participants who are eligible to make elective deferrals under Section 4.1(a) and who have attained age fifty (50) before the close of the taxable year shall be eligible to make catch-up contributions in accordance with, and subject to the limitations of, Section 414(v) of the Code, as adjusted by the Secretary of the Treasury for cost-of-living increases under Section 414(v)(2)(C) of the Code.

EMPLOYER CONTRIBUTIONS

Employer Matching Contributions. For each payroll period, the Employer may contribute to the Plan, on behalf of each Participant, a discretionary matching contribution equal to a percentage (as determined by the Employer’s board of directors) of the elective deferrals (within the meaning of Section 4.1) and/or after- tax contributions (under Section 4.5) that were made or could have been made but

Company Contributions. Each payroll period, the Employer shall make a “Company Contribution” on behalf of Non-union Participants who elected to opt- out of the Employer’s defined benefit plan as of January 1, 2010, and/or are first eligible to participate in the Plan (including those rehired) on and after January 1, 2010. Such “Company Contribution” shall be in an amount equal to four percent (4%) of each such Participant’s Compensation for each payroll period.

ROLLOVERS AND TRANSFERS OF FUNDS FROM OTHER PLANS. With the approval of the Administrator, there may be paid to the Trustee amounts which have been held under the following types of plans:

a qualified plan described in Section 401(a) or 403(a) of the Code, excluding after- tax employee contributions and including designated Roth contributions under Section 402A of the Code;

an annuity contract described in Section 403(b) of the Code, excluding after-tax employee contributions and including designated Roth contributions under Section 402A of the Code;

an eligible plan under Section 457(b) of the Code which is maintained by a state, political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a state, excluding after-tax employee contributions and including designated Roth contributions under Section 402A of the Code; and

an individual retirement account which was used solely as a conduit from a qualified plan described in Section 401(a) of the Code.

TIMING OF CONTRIBUTIONS. Employer contributions shall be made to the Plan no later than the time prescribed by law for filing the Employer’s federal income tax return (including extensions) for its taxable year ending with or within the Plan Year. Elective deferrals under Section 4.1, loan repayments under Section 8.1, and any after-tax contributions under Section 4.5 shall be paid to the Plan as soon as administratively

EMPLOYEE AFTER-TAX CONTRIBUTIONS. A Participant shall be permitted to make after-tax contributions to the Plan in accordance with procedures established by the Administrator which shall be consistently applied and which may be changed from time to time. A Participant may prospectively elect to change or revoke the amount (or percentage) of his after-tax contributions during the Plan Year in accordance with procedures established by the Administrator.

INVESTMENT OF ACCOUNTS AND ACCOUNTING RULES

Investment Funds. The investment of Participants’ Accounts shall be made in a manner consistent with the provisions of the Trust. The Administrator, in its discretion, may allow the Trust to provide for separate funds for the directed investment of each Participant’s Account. The Plan shall permit investments in Employer stock and accordingly, a separate Employer stock fund shall be created and a portion of such stock fund shall be invested in cash and cash equivalents for liquidity purposes.

Participant Direction of Investments. In the event Participants’ Accounts are subject to their investment direction, each Participant (including, for this purpose, any former Employee, Beneficiary, or “alternate payee” (within the meaning of Section 14.4 below) with an Account balance) may direct how his Account (or such portion thereof which is subject to his investment direction) is to be invested among the available investment funds in the percentage multiples established by the Administrator. A Participant may elect to invest up to one hundred percent (100%) of his Account in Employer stock. In the event a Participant fails to make an investment election, with respect to all or any portion of his Account subject to his investment direction, the Trustee shall invest all or such portion of his Account in the default investment fund to be designated by the Administrator. A Participant may change his investment election, with respect to future contributions and, if applicable, forfeitures, and/or amounts previously accumulated in the Participant’s Account, in accordance with procedures established by the Administrator. Any such change in a Participant’s investment election shall be effective at such time as may be prescribed by the Administrator. However, where it deems appropriate, and subject to the requirements of applicable law, the Administrator may decline to implement, or otherwise limit the frequency by which a Participant may direct the investment of his Account. If the Plan’s recordkeeper or investments are changed, the Administrator may apply such administrative rules and procedures as are necessary to provide for the transfer of records and/or assets, including, without limitation, the suspension of Participant’s investment directions, withdrawals and distributions for such period of time as is necessary, and the transfer of Participants’ Accounts to designated funds or an interest bearing account until such change has been completed.

Divestment of Employer Securities: If any portion of a Participant’s Account is invested in publicly-traded employer securities (within the meaning of Section 407(d)(1) of the Employee Retirement Income Security Act of 1974), the Participant may direct the Trustee to divest such securities and to reinvest the proceeds in other investment options available under the Plan subject to the provisions of Code Section 401(a)(35), in accordance with rules and procedures established by the Administrator from time to time.

Allocation of Investment Experience. As of each Valuation Date, the investment fund(s) of the Trust shall be valued at fair market value, and the income, loss, appreciation and depreciation (realized and unrealized), and any paid expenses of the Trust attributable to such fund shall be apportioned among Participants’ Accounts within the fund based upon the value of each Account within the fund as of the preceding Valuation Date.

Allocation of Contributions. Employer contributions shall be allocated to the Account of each eligible Participant as of the last day of the period for which the contributions are made, or as soon as administratively possible thereafter. Forfeitures which arise in a Plan Year and which are allocated to Participants’ Accounts shall be allocated as of the last day of such Plan Year, or as soon as administratively possible thereafter.

Manner and Time of Debiting Distributions. For any Participant who is entitled to receive a distribution from his Account, such distribution shall be made in accordance with the provisions of Section 7.1 and Section 7.2. The amount distributed shall be based upon the fair market value of the Participant’s vested Account as of the Valuation Date preceding the distribution.

ALLOCATION OF SERVICE CREDIT. Any amounts deposited to the Plan by a service provider pursuant to an agreement between the Employer and the service provider (“Service Credit”) shall be used to pay Plan administrative expenses. To the extent that the Service Credit for a calendar year exceeds the Plan administrative expenses incurred through March 31 (or prior business day) of the following calendar year, the excess (subject to such de minimis amount as may be established, which amount shall be used to pay future Plan administrative expenses) shall be allocated as of such March 31 (or the prior business day) to Participants with Account balances on such allocation date. The Account of each Participant eligible to receive such allocation shall be credited with an amount equal to the total excess Service Credit multiplied by a fraction, the numerator of which is the Participant’s Account balance as of the date on which such allocation is made, and the denominator of which is the Account balances of all eligible Participants as of that date.

VESTING. A Participant shall at all times have a nonforfeitable (vested) right to his Account derived from elective deferrals (within the meaning of Section 4.1), after-tax contributions (under Section 4.5), any Company Contributions (under Section 4.2(b) and/or Appendix C), Employer Fail-Safe Contributions, “Qualified Matching Contributions” (within the meaning of Section 10.2 below), and rollovers or transfers from other plans, as adjusted for investment experience. Except as otherwise provided with respect to Normal Retirement, Disability, death, or as otherwise indicated in Section 4.2(a), a Participant shall have a nonforfeitable (vested) right to a percentage of the value of his Account derived from discretionary Employer matching contributions under Section 4.2(a) as follows:

Less than 1 year

1 year but less than 2

2 years but less than 3

3 years and thereafter

FORFEITURE OF NONVESTED BALANCE. The nonvested portion of a Participant’s Account, as determined in accordance with Section 6.1, shall be forfeited as of the earlier of (i) as soon as administratively practical following the date on which the Participant receives distribution of his vested Account or (ii) as soon as administratively practical after the last day of the Plan Year in which the Participant incurs five (5) consecutive Breaks in Service. However, no forfeiture shall occur solely as a result of a Participant’s withdrawal of Employee after-tax contributions. The amount forfeited shall be used to pay Plan administrative expenses, used to reduce Employer contributions under the Plan or used to restore previously forfeited amounts under this Section 6.2. Forfeitures shall be used in accordance with the terms of the Plan no later than the end of the Plan Year following the Plan Year in which the forfeiture occurs.

the Participant resumes employment prior to incurring five (5) consecutive Breaks in Service; and

the Participant repays to the Plan, as of the earlier of (i) the date which is five (5) years after his reemployment date or (ii) the date which is the last day of the period in which the Participant incurs five (5) consecutive Breaks in Service commencing after distribution of the Participant’s vested Account, an amount equal to the total distribution derived from Employer contributions under Section 4.2 and, if applicable, Section 13.3.

DISTRIBUTION OF LESS THAN ENTIRE VESTED ACCOUNT BALANCE. If a distribution (including a withdrawal) of any portion of a Participant’s Account is made to the Participant at a time when he has a vested percentage in such Account equal to less than one-hundred percent (100%), a separate record shall be maintained of said Account balance. The Participant’s vested interest at any time in this separate account shall be an amount equal to the formula P(AB+D)-D, where P is the vested percentage at the relevant time, AB is the Account balance at the relevant time, and D is the amount of the distribution (or withdrawal) made to the Participant.

NORMAL RETIREMENT. A Participant who is in the employment of the Employer at his Normal Retirement Age shall have a nonforfeitable interest in one hundred percent (100%) of his Account, if not otherwise one hundred percent (100%) vested under the vesting schedule in Section 6.1. Payment of such Participant’s vested Account balance shall be made at the time and in the manner specified in Article Seven. Notwithstanding the foregoing, a Participant who continues employment with the Employer after his Normal Retirement Age shall continue to participate under the Plan.

DISABILITY. If a Participant incurs a Disability while employed by the Employer, the Participant shall have a nonforfeitable interest in one hundred percent (100%) of his Account, if not otherwise one hundred percent (100%) vested under Section 6.1.

Subject to the following provisions of this Section, unless the Participant elects otherwise in accordance with provisions of the Plan, distribution of the Participant’s vested Account shall be made or commence no later than the sixtieth (60) day after the later of the close of the Plan Year in which: (a) the Participant attains age sixty-five (65) (or Normal Retirement Date, if earlier), (b) occurs the tenth (10^th) anniversary of the year in which the Participant commenced participation in the Plan, or (c) the Participant severs employment with the Employer. Distribution shall not be made to a Participant without his consent (and spouse’s consent, if required) if his vested Account exceeds $5,000 and such Account is immediately distributable (within the meaning of Section 1.411(a)-11(c)(4) of the IRS Regulations).

MINIMUM DISTRIBUTION REQUIREMENTS.

General Rules.

Effective Date. The provisions of this Article will apply for purposes of determining required minimum distributions.

Precedence. The requirements of this Article shall take precedence over any inconsistent provisions of the Plan; provided, however, that this Article shall not require the Plan to provide any form of benefit, or any option, not otherwise provided under Section 7.1.

Requirements of Treasury Regulations Incorporated. All distributions required under this Article shall be determined and made in accordance with the Treasury regulations under Section 401(a)(9) of the Code and the minimum distribution incidental benefit requirement of Section 401(a)(9)(G) of the Code.

Time and Manner of Distribution

Required Beginning Date. The Participant’s vested Account shall be distributed, or begin to be distributed, to the Participant no later than the Participant’s required beginning date.

Death of Participant Before Distributions Begin. If the Participant dies before distributions begin, the Participant’s vested Account shall be distributed, or begin to be distributed, no later than as follows:

If the Participant’s surviving spouse is the Participant’s sole designated Beneficiary, distribution of the Participant’s vested Account shall be completed by the December 31 of the calendar year containing the fifth anniversary of the Participant’s death, unless distribution is to be made over the surviving spouse’s life or over a period certain not exceeding the life expectancy of the surviving spouse (if permitted under Section 7.1 of the Plan), in which case distribution shall commence by December 31 of the calendar year immediately following the calendar year in which the Participant died, or by December 31 of the calendar year in which the Participant would have attained age 70¹⁄₂, if later.

If the Participant’s surviving spouse is not the Participant’s sole designated Beneficiary, distribution of the Participant’s vested Account shall be completed by the December 31 of the calendar year containing the fifth anniversary of the Participant’s death, unless distribution is to be made over the life or over a period certain not exceeding the life expectancy of the designated Beneficiary (if permitted under Section 7.1 of the Plan), in which case distribution shall commence by December 31 of the calendar year immediately following the calendar year in which the Participant died.

If there is no designated Beneficiary as of September 30 of the year following the year of the Participant’s death, the Participant’s vested Account shall be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death.

If the Participant’s surviving spouse is the Participant’s sole designated Beneficiary and the surviving spouse dies after the Participant but before distributions to the surviving spouse begin, this Section 7.4(b), other than Section 7.4(b)(2)(A), shall apply as if the surviving spouse were the Participant.

Forms of Distribution. Unless the Participant’s interest is distributed in the form of an annuity purchased from an insurance company or in a single sum on or before the required beginning date, as of the first distribution calendar year, distributions shall be made in accordance with Sections 7.4(c) and (d). If the Participant’s interest is distributed in the form of an annuity purchased from an insurance company, distributions thereunder shall be made in accordance with the requirements of Section 401(a)(9) of the Code and the Treasury regulations.

Required Minimum Distributions During Participant’s Lifetime.

Amount of Required Minimum Distribution for Each Distribution Calendar Year. During the Participant’s lifetime, the minimum amount that shall be distributed for each distribution calendar year is the lesser of:

the quotient obtained by dividing the Participant’s vested Account balance by the distribution period in the Uniform Lifetime Table set forth in Section 1.401(a)(9)-9, Q&A-2, of the Treasury regulations, using the Participant’s age as of the Participant’s birthday in the distribution calendar year; or

if the Participant’s sole designated Beneficiary for the distribution calendar year is the Participant’s spouse, the quotient obtained by dividing the Participant’s vested Account balance by the number in the Joint and Last Survivor Table set forth in Section 1.401(a)(9)-9, Q&A-3, of the Treasury regulations, using the Participant’s and spouse’s attained ages as of the Participant’s and spouse’s birthdays in the distribution calendar year.

Lifetime Required Minimum Distributions Continue Through Year of Participant’s Death. Required minimum distributions shall be determined under this Section 7.4(c) beginning with the first distribution calendar year and up to and including the distribution calendar year that includes the Participant’s date of death.

Required Minimum Distributions After Participant’s Death.

Death On or After Date Distributions Begin.

Participant Survived by Designated Beneficiary. Subject to the provisions of this Article, if the Participant dies on or after the date distributions begin and there is a designated Beneficiary, the minimum amount that shall be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s vested Account balance by the longer of the remaining life expectancy of the Participant or the remaining life expectancy of the Participant’s designated Beneficiary, determined as follows:

The Participant’s remaining life expectancy is calculated using the age of the Participant in the year of death, reduced by one for each subsequent year.

If the Participant’s surviving spouse is the Participant’s sole designated Beneficiary, the remaining life expectancy of the surviving spouse is calculated for each distribution calendar year after the year of the Participant’s death using the surviving spouse’s age as of the spouse’s birthday in that year. For distribution calendar years after the year of the surviving spouse’s death, the remaining life expectancy of the surviving spouse is calculated using the age of the surviving spouse as of the spouse’s birthday in the calendar year of the spouse’s death, reduced by one for each subsequent calendar year.

If the Participant’s surviving spouse is not the Participant’s sole designated Beneficiary, the designated Beneficiary’s remaining life expectancy is calculated using the age of the Beneficiary in the year following the year of the Participant’s death, reduced by one for each subsequent year.

No Designated Beneficiary. If the Participant dies on or after the date distributions begin and there is no designated Beneficiary as of September 30 of the year after the year of the Participant’s death, the minimum amount that shall be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s vested Account balance by the Participant’s remaining life expectancy calculated using the age of the Participant in the year of death, reduced by one for each subsequent year.

Death Before Date Distributions Begin.

Participant Survived by Designated Beneficiary. If the Participant dies before the date distributions begin and there is a designated Beneficiary, the minimum amount that shall be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s vested Account balance by the remaining life expectancy of the Participant’s designated Beneficiary, determined as provided in Section 7.4(d)(1).

No Designated Beneficiary. If the Participant dies before the date distributions begin and there is no designated Beneficiary as of September 30 of the year following the year of the Participant’s death, distribution of the Participant’s entire interest shall be completed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death.

Death of Surviving Spouse Before Distributions to Surviving Spouse Are Required to Begin. If the Participant dies before the date distributions begin, the Participant’s surviving spouse is the Participant’s sole designated Beneficiary, and the surviving spouse dies before distributions are required to begin to the surviving spouse under Section 7.4(b)(2)(A), this Section 7.4(d) shall apply as if the surviving spouse were the Participant.

Definitions.

Designated Beneficiary. The individual who is designated as the Beneficiary under Section 7.6 of the Plan and is the designated Beneficiary under Section 401(a)(9) of the Code and Section 1.401(a)(9)-4, of the Treasury regulations.

Distribution Calendar Year. A calendar year for which a minimum distribution is required. For distributions beginning before the Participant’s death, the first distribution calendar year is the calendar year immediately preceding the calendar year which contains the Participant’s required beginning date. For distributions beginning after the Participant’s death, the first distribution calendar year is the calendar year in which distributions are required to begin under Section 7.4(b)(2). The required minimum distribution for the Participant’s first distribution calendar year shall be made on or before the Participant’s required beginning date. The required minimum distribution for other distribution calendar years, including the required minimum distribution for the distribution calendar year in which the Participant’s required beginning date occurs, shall be made on or before December 31 of that distribution calendar year.

Life Expectancy. Life expectancy as computed by use of the Single Life Table in Section 1.401(a)(9)-9, Q&A-1, of the Treasury regulations.

Participant’s Vested Account Balance. The vested Account balance as of the last valuation date in the calendar year immediately preceding the distribution calendar year (valuation calendar year) increased by the amount of any contributions made and allocated or forfeitures allocated to the vested Account balance as of dates in the valuation calendar year after the valuation dateand decreased by distributions made in the valuation calendar year after the valuation date. The vested Account balance for the valuation calendar year includes any amounts rolled over or transferred to the Plan either in the valuation calendar year or in the distribution calendar year if distributed or transferred in the valuation calendar year.

Required Beginning Date. The date specified in Section 7.2 of the Plan.

AMOUNT OF DEATH BENEFIT

Death Before Termination of Employment. In the event of the death of a Participant while in the employ of the Employer, vesting in the Participant’s Account shall be one hundred percent (100%), if not otherwise one hundred percent (100%) vested under Section 6.1, with the credit balance of the Participant’s Account being payable to his Beneficiary.

Death After Termination of Employment. In the event of the death of a former Participant after termination of employment, but prior to the complete distribution of his vested Account balance under the Plan, the undistributed vested balance of the Participant’s Account shall be paid to the Participant’s Beneficiary.

DESIGNATION OF BENEFICIARY. Each Participant shall designate a Beneficiary in a manner acceptable to the Administrator to receive payment of any death benefit payable hereunder if such Beneficiary should survive the Participant. However, no Participant who is married shall be permitted to designate a Beneficiary other than his spouse, unless the Participant’s spouse has signed a written consent witnessed by a notary public, which provides for the designation of an alternate Beneficiary. Notwithstanding the foregoing, spousal consent hereunder shall not be required if it is established to the satisfaction of the Administrator that the spouse’s consent cannot be obtained because such spouse cannot be located, or because of such other circumstances as may be prescribed in regulations pursuant to Section 417 of the Code.

DISTRIBUTION OF DEATH BENEFITS. Subject to the provisions of Section 7.2, the Beneficiary shall be allowed to designate the mode of receiving benefits in accordance with Section 7.1, unless the Participant had designated a method in writing and indicated that the method was not revocable by the Beneficiary.

Distribution Beginning Before Death - If the Participant dies after distribution of his vested Account has commenced, any survivor’s benefit must be paid at least as rapidly as under the method of payment in effect at the time of the Participant’s death.

Distribution Beginning After Death - If the Participant dies before distribution of his vested Account has commenced, distribution of the Participant’s vested Account shall be completed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death, except as provided below:

if the Participant’s surviving spouse is the Participant’s sole designated Beneficiary, the date distribution is required to begin shall not be earlier than the later of (A) December 31 of the calendar year immediately following the calendar year in which the Participant died and (B) December 31 of the calendar year in which the Participant would have attained age seventy and one-half (70¹⁄₂).

ELIGIBLE ROLLOVER DISTRIBUTIONS. Notwithstanding the foregoing provisions of this Article Seven, the provisions of this Section 7.8 shall apply to distributions made under the Plan.

A “distributee” (as hereinafter defined) may elect, at the time and in the manner prescribed by the Administrator, to have any portion of an “eligible rollover distribution” (as hereinafter defined) paid directly to an eligible retirement plan specified by the distributee in a direct rollover.

Definitions:

Eligible Rollover Distribution. An eligible rollover distribution is any distribution of all or any portion of the balance to the credit of the distributee, except that an eligible rollover distribution does not include: any distribution that is one of a series of substantially equal periodic payments (not less frequently than annually) made for the life (or life expectancy) of the distributee or the joint lives (or joint life expectancies) of the distributee and the distributee’s designated Beneficiary, or for a specified period of ten (10) years or more; any distribution to the extent such distribution is required under Section 401(a)(9) of the Code; and as a hardship distribution (within the meaning of Code Section 401(k) and the regulations promulgated thereunder). A portion of a distribution shall not fail to be an eligible rollover distribution merely because the portion consists of after-tax employee contributions which are not includible in gross income. However, such portion may be transferred only to (1) a traditional individual retirement account or annuity described in Section 408(a) or (b) of the Code (a “traditional IRA”) or a Roth individual retirement account or annuity described in Section 408A of the Code (a “Roth IRA”); or (2) to a qualified plan or an annuity contract described in Section 401(a) and 403(b) of the Code, respectively, that agrees to separately account for amounts so transferred (and earnings thereon), including separately accounting for the portion of such distribution which is includible in gross income and the portion of such distribution which is not so includible.

Eligible Retirement Plan. An eligible retirement plan is an eligible plan under Section 457(b) of the Code which is maintained by a state, political

Distributee. A distributee includes an Employee or former Employee. In addition, the Employee’s or former Employee’s surviving spouse, and the Employee’s or former Employee’s spouse or former spouse who is an alternate payee under a qualified domestic relations order, as defined in Section 414(p) of the Code, are distributees with regard to the interest of the spouse or former spouse. Finally, a distributee also includes the Employee’s or former Employee’s non-spouse designated Beneficiary, in which case, the distribution can only be transferred to an inherited IRA established on behalf of the non-spouse designated Beneficiary for the purpose of receiving the distribution.

Direct Rollover. A direct rollover is a payment by the Plan to the eligible retirement plan specified by the distributee.

If a distribution is one to which Sections 401(a)(11) and 417 of the Code do not apply, such distribution may commence less than thirty (30) days after the notice required under Section 1.411(a)-11(c) of the Income Tax Regulations is given, provided that:

the Administrator clearly informs the Participant that the Participant has a right to a period of at least thirty (30) days after receiving the notice to consider the decision of whether or not to elect a distribution (and, if applicable, a particular distribution option), and

the Participant, after receiving the notice, affirmatively elects a distribution.

The distribution notice required herein, shall include a description of the Participant’s right, if any, to defer distribution and the consequences of failing to defer receipt of the distribution in accordance with the requirements of applicable law.

IN-PLAN ROTH CONVERSIONS. Effective April 1, 2019, a Participant may elect to transfer amounts from his vested non-Roth Account to his Roth account under the Plan in accordance with Section 402A(c)(4) of the Code and regulatory guidance and procedures established by the Administrator. The Plan shall maintain such records as are necessary for the proper reporting of in-plan Roth conversions.

LOANS

Permissible Amount and Procedures. Upon the application of an active Participant, the Administrator may, in accordance with a uniform and nondiscriminatory policy, direct the Trustee to grant a loan to the Participant, which loan shall be secured by the Participant’s vested Account balance. The rate of interest on any such loan shall be equal to the “Prime Rate” (as reported in The Wall Street Journal on the date the loan is initiated) plus one percent (1%). Participant loans shall be treated as segregated investments, and interest repayments shall be credited only to the Participant’s Account.

Limitation on Amount of Loans. A Participant’s loan shall not exceed the lesser of:

$50,000, which amount shall be reduced by the highest outstanding loan balance during the preceding twelve (12)-month period; or

one-half (¹⁄₂) of the vested value of the Participant’s Account, determined as of the Valuation Date preceding the date of the Participant’s loan.

HARDSHIP DISTRIBUTIONS. In the case of a financial hardship resulting from a proven immediate and heavy financial need, an active Participant may receive a distribution not to exceed the lesser of (i) the vested value of the Participant’s Account, without regard to earnings received on elective deferrals (within the meaning of Section 4.1) after December 31, 1988, and without regard to any Fail-Safe Contributions and Qualified Matching Contributions (within the meaning of Section 10.2 below) or any Employer contributions made pursuant to Section 10.2 and/or 10.3, or (ii) the amount necessary to satisfy the financial hardship. The amount of any such immediate and heavy financial need may include any amounts necessary to pay Federal, state or local income taxes reasonably anticipated to result from the distribution. Such distribution shall be made in accordance with nondiscriminatory and objective standards and procedures consistently applied by the Administrator. For purposes of this Section, an active Participant shall include an Employee who has severed employment with the Employer but is still employed by a member of the Employer’s related group (within the meaning of Section 2.5(b)) and who has an Account under the Plan.

The distribution is not in excess of the amount of the immediate and heavy financial need of the Participant;

The Participant has obtained all distributions (including distributions of ESOP dividends under Section 404(k) of the Code), other than hardship distributions, and all nontaxable (at the time of the loan) loans currently available under all plans maintained by the Employer;

The Participant is prohibited, under the terms of the Plan or an otherwise legally enforceable agreement, from making elective deferrals (within the meaning of Section 4.1) and any after-tax contributions under Section 4.5 to the Plan and all other plans maintained by the Employer for six (6) months after receipt of the hardship distribution. For this purpose the phrase “all other plans maintained by the Employer” means all qualified and nonqualified plans of deferred compensation maintained by the Employer. The phrase also includes a stock option, stock purchase, or similar plan, or a cash or deferred arrangement that is part of a cafeteria plan within the meaning of Section 125 of the Code. However, it does not include the mandatory employee contribution portion of a defined benefit plan. It also does not include a health or welfare benefit plan, including one that is part of a cafeteria plan within the meaning of Section 125 of the Code.

A Participant shall not be prohibited from making elective deferrals (within the meaning of Section 4.1) or any after-tax contributions (within the meaning of Section 4.5) to the Plan, and all other plans maintained by the Employer (except as otherwise provided in such plans), after a hardship distribution.

Effective for distributions on or after January 14, 2019 (or, if later, the date the Plan commenced using John Hancock Retirement Plan Services, LLC hardship distribution forms), the reason set forth in subsection (f) above shall instead be determined as follows: (f) repair damage to the Participant’s principal residence that would qualify for a casualty loss deduction under Section 165 of the Code (determined without regard to whether the loss exceeds ten percent (10%) of adjusted gross income, and determined without regard to Section 165(h)(5) of the Code).

The standard for determining whether a hardship distribution is necessary to satisfy an immediate and heavy financial need is changed to the following:

The distribution is not in excess of the amount of the immediate and heavy financial need of the Participant;

The Participant has obtained all currently available distributions (including distributions of ESOP dividends under Section 404(k) of the Code), but not hardship distributions, under the Plan and all other plans of deferred compensation, whether qualified or nonqualified, maintained by the Employer, and all nontaxable (at the time of the loan) loans currently available under the Plan; and

The Participant represents, in accordance with procedures established by the Administrator, that he has insufficient cash or other liquid assets reasonably available to satisfy the financial need. The Administrator may rely on the Participant’s representation unless the Administrator has actual knowledge to the contrary.

WITHDRAWALS AFTER AGE 59¹⁄₂. After attaining age fifty-nine and one-half (59¹⁄₂), an active Participant may withdraw from the Plan a sum (a) not in excess of the credit balance of his vested Account and (b) not less than such minimum amount as the Administrator may establish from time to time to facilitate administration of the Plan. Any such withdrawals shall be made in accordance with nondiscriminatory and objective standards and procedures consistently applied by the Administrator. For purposes of this Section, an active Participant shall include an Employee who has severed employment with the Employer but is still employed by a member of the Employer’s related group (within the meaning of Section 2.5(b)) and who has an Account under the Plan.

WITHDRAWALS OF AFTER-TAX CONTRIBUTIONS. An active Participant may withdraw from the Plan a sum (a) not in excess of the credit balance of the Participant’s Account attributable to any after-tax contributions made to the Plan, including any earnings thereon, and (b) not less than such minimum amount as the Administrator may establish from time to time to facilitate administration of the Plan. Any such withdrawals shall be made in accordance with nondiscriminatory and objective standards and procedures consistently applied by the Administrator. For purposes of this Section, an active Participant shall include an Employee who has severed employment with the Employer but is still employed by a member of the Employer’s related group (within the meaning of Section 2.5(b)) and who has an Account under the Plan.

WITHDRAWALS OF ROLLOVER CONTRIBUTIONS. An active Participant may withdraw from the Plan a sum (a) not in excess of the credit balance of the Participant’s Account attributable to any rollover contributions made to the Plan, including any earnings thereon, and (b) not less than such minimum amount as the Administrator may establish from time to time to facilitate administration of the Plan. Any such withdrawals shall be

HEART ACT PROVISIONS.

Death benefits. In the case of a Participant’s death occurring on or after January 1, 2007, if a Participant dies while performing qualified military service (as defined in Code Section 414(u)), the Beneficiary(ies) (or surviving spouse, if the qualified joint and survivor annuity or qualified pre-retirement survivor annuity rules apply) of the Participant shall be entitled to any additional benefits (other than benefit accruals relating to the period of qualified military service) provided under the Plan as if the Participant had resumed employment and then terminated employment on account of death. In addition, vesting service credit for the deceased Participant’s period of qualified military service shall be credited to the extent required by Code Section 401(a)(37).

Differential wage payments. For years beginning after December 31, 2008, (i) a Participant receiving a differential wage payment, as defined by Code Section 3401(h)(2), shall be treated as an Employee of the Employer making the payment, (ii) the differential wage payment shall be treated as Compensation, and (iii) the Plan shall not be treated as failing to meet the requirements of any provision described in Code Section 414(u)(1)(C) by reason of any contribution or benefit which is based on the differential wage payment.

Severance from employment. For years beginning after December 31, 2008 and for purposes of Code Section 401(k)(2)(B)(i)(I), an individual shall be treated as having severed from employment during any period the individual is performing service in the uniformed services described in Code Section 3401(h)(2)(A).

PLAN ADMINISTRATION. The Employer shall be the Plan Administrator, hereinbefore and hereinafter called the Administrator, and a “named fiduciary” (for purposes of Section 402(a)(1) of the Employee Retirement Income Security Act of 1974, as amended from time to time (“ERISA”)) of the Plan, unless the Employer, by action of its board of directors, shall designate a person or committee of persons to be the Administrator. The Employer, by action of its board of directors, may also designate a person, a committee of persons, and/or other entity as a named fiduciary or named fiduciaries. The administration of the Plan, as provided herein, including a determination of the payment of benefits to Participants and their Beneficiaries, shall be the responsibility of the Administrator; provided, however, that the Administrator may delegate any of its powers, authority, duties or responsibilities to any person or committee of persons, such delegation to be in accordance with ERISA Section 405. The Administrator shall have full discretion to interpret the terms of the Plan, to determine factual questions that arise in the course of administering the Plan, to adopt rules and regulations regarding the administration of the Plan, to determine the conditions under which benefits become payable under the Plan, and to make any other determinations that the Administrator believes are necessary and advisable for the administration of the Plan. Any determination made by the Administrator shall be final and binding on all parties, and shall be given the maximum deference allowed by law.

CLAIMS PROCEDURE

the specific references to the pertinent Plan provisions on which the denial is based;

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

a statement that any appeal of the denial must be made by giving to the Administrator, within sixty (60) days after receipt of the denial of the claim, written notice of such appeal, such notice to include a full description of the pertinent issues and basis of the claim; and

a statement about the claimant’s right to bring civil action under Section 502(a) under ERISA if the claim is denied on review.

DISTRIBUTION OF EXCESS ELECTIVE DEFERRALS. Notwithstanding any other provision of the Plan, “Excess Elective Deferrals” (as defined below) (and income or loss allocable thereto, including all earnings, expenses and appreciation or depreciation in value, whether or not realized) shall be distributed no later than each April 15 to Participants who claim Excess Elective Deferrals for the preceding calendar year. Distribution of Excess Elective Deferrals for a year shall be made first from the portion of the Participant’s vested account consisting of any pre-tax contributions made under Section 4.1, then from any “designated Roth contributions” made under Section 4.1, unless the Participant specifies otherwise in accordance with the rules and procedures established by the Administrator.

LIMITATIONS ON 401(k) CONTRIBUTIONS

Actual Deferral Percentage Test (“ADP Test”). Amounts contributed as elective deferrals under Section 4.1(a) and, if so elected by the Employer, “Qualified Matching Contributions” (as defined below) and any Fail-Safe Contributions made under this Section, are considered to be amounts deferred pursuant to Section 401(k) of the Code. For purposes of this Section, these amounts are referred to as the “deferred amounts.” For purposes of the “actual deferral percentage test” described below, (i) such deferred amounts must be made before the last day of the twelve (12)-month period immediately following the Plan Year to which the contributions relate, and (ii) the deferred amounts relate to Compensation that (A) would have been received by the Participant in the Plan Year but for the Participant’s election to make deferrals, (B) is attributable to services performed by the Participant in the Plan Year, or (C) is contributed in the form of “designated Roth contributions” pursuant to Section 402A of the Code and, but for the Participant’s election to make deferrals, would have been received by the Participant within two and one-half (2¹⁄₂) months after the close of the Plan Year. The Employer shall maintain records sufficient to demonstrate satisfaction of the actual deferral percentage test and the deferred amounts used in such test.

The actual deferral percentage for the eligible Participants who are Highly- Compensated Employees for the Plan Year shall not exceed the actual deferral percentage for eligible Participants who are Nonhighly- Compensated Employees for the current Plan Year multiplied by 1.25; or

The actual deferral percentage for eligible Participants who are Highly- Compensated Employees for the Plan Year shall not exceed the actual deferral percentage of eligible Participants who are Nonhighly- Compensated Employees for the current Plan Year multiplied by two (2), provided that the actual deferral percentage for eligible Participants who are Highly-Compensated Employees for the Plan Year does not exceed the actual deferral percentage for eligible Participants who are Nonhighly- Compensated Employees by more than two (2) percentage points.

“compensation” - shall mean compensation used for the actual deferral percentage test.

“representative contribution rate” – shall mean the greater of:

the lowest applicable contribution rate (defined below) of any eligible Nonhighly-Compensated Employee among a group of eligible Nonhighly-Compensated Employees that consists of at least fifty percent (50%) of the total eligible Nonhighly-Compensated Employees for the Plan Year, or

the lowest applicable contribution rate of any eligible Nonhighly- Compensated in the group of all eligible Nonhighly-Compensated Employees for the Plan Year and who is employed by the Employer on the last day of the Plan Year.

Distributions of Excess Contributions.

In General. If the actual deferral percentage test of Section 10.2(a) is not satisfied for a Plan Year, then the “excess contributions”, and income allocable thereto, shall be distributed, to the extent required under Treasury regulations, no later than the last day of the Plan Year following the Plan Year for which the excess contributions were made. However, if such excess contributions are distributed later than two and one-half (2¹⁄₂) months (or such longer period as permitted by applicable law and/or regulatory guidance) following the last day of the Plan Year in which such excess contributions were made, a ten percent (10%) excise tax shall be imposed upon the Employer with respect to such excess contributions.

Excess Contributions. For purposes of this Section, “excess contributions” shall mean, with respect to any Plan Year, the excess of:

The aggregate amount of Employer contributions actually taken into account in computing the numerator of the actual deferral percentage of Highly-Compensated Employees for such Plan Year, over

The maximum amount of such contributions permitted by the ADP Test under Section 10.2(a) (determined by hypothetically reducing contributions made on behalf of Highly-Compensated Employees in order of the actual deferral percentages, beginning with the highest of such percentages).

Determination of Income. Excess contributions shall be adjusted for any income or loss. The income or loss allocable to excess contributions allocated to each Participant shall be the income or loss allocable to the Participant’s deferred amounts for the Plan Year multiplied by a fraction, the numerator of which is the excess contributions made on behalf of the Participant for the Plan Year, and the denominator of which is the Participant’s Account balance attributable to the Participant’s deferred amounts on the last day of the Plan Year.

Accounting for Excess Contributions. Excess contributions shall be distributed from that portion of the Participant’s Account attributable to such deferred amounts as follows: first from any pre-tax contributions made under Section 4.1, then from any “designated Roth contributions” made under Section 4.1, unless the Participant specifies otherwise in accordance with the rules and procedures established by the Administrator.

NONDISCRIMINATION TEST FOR EMPLOYER MATCHING CONTRIBUTIONS AND AFTER-TAX CONTRIBUTIONS

Average Contribution Percentage Test (“ACP Test”). To the extent required by applicable law, the provisions of this Section shall apply if Employer matching contributions are made in any Plan Year under Section 4.2(a) and such matching contributions are not used to satisfy the actual deferral percentage test of Section 10.2 and/or in the event Employee after-tax contributions are made to the Plan under Section 4.6. Any Employee after-tax contributions that are used to satisfy the average contribution percentage test shall satisfy the requirements of Section 1.401(m)-2(a)(6) of the IRS Treasury Regulations.

The average contribution percentage for eligible Participants who are Highly-Compensated Employees for the Plan Year shall not exceed the average contribution percentage for eligible Participants who are Nonhighly-Compensated Employees for the current Plan Year multiplied by 1.25; or

The average contribution percentage for eligible Participants who are Highly-Compensated Employees for the Plan Year shall not exceed the average contribution percentage for eligible Participants who are Nonhighly-Compensated Employees for the current Plan Year multiplied by two (2), provided that the average contribution percentage for eligible Participants who are Highly-Compensated Employees for the Plan Year does not exceed the average contribution percentage for eligible Participants who are Nonhighly-Compensated Employees by more than two (2) percentage points.

Distribution of Excess Aggregate Contributions.

In General. If the nondiscrimination tests of Section 10.3(a) are not satisfied for a Plan Year, then the “excess aggregate contributions”, and any income allocable thereto, shall be forfeited, if otherwise forfeitable, no later than the last day of the Plan Year following the Plan Year for which the nondiscrimination tests are not satisfied, and shall be used to reduce Employer matching contributions under the Plan. To the extent that such “excess aggregate contributions” are nonforfeitable, such excess aggregate contributions shall be distributed to the Participant on whose behalf the excess contributions were made no later than the last day of the Plan Year following the Plan Year for which such “excess aggregate contributions” were made. However, if such excess aggregate contributions are distributed later than two and one-half (2¹⁄₂) months (or such longer period as permitted by applicable law and/or regulatory guidance) following the last day of the Plan Year in which such excess aggregate contributions were made, a ten percent (10%) excise tax shall be imposed upon the Employer with respect to such excess aggregate contributions. For purposes of the limitations of Section 11.1(b)(1) of the Plan, excess aggregate contributions shall be considered annual additions.

Excess Aggregate Contributions. For purposes of this Section, “excess aggregate contributions” shall mean, with respect to any Plan Year, the excess of:

The aggregate amount of Employer matching contributions and, if applicable, Employee after-tax contributions, and elective deferrals under Section 4.1 (to the extent not used to satisfy the actual deferral percentage test of Section 10.2) actually taken into account in computing the numerator of the actual contribution percentage of Highly-Compensated Employees for such Plan Year, over

The maximum amount of such contributions permitted by the ACP Test under Section 10.3(a) (determined by hypothetically reducing contributions made on behalf of Highly-Compensated Employees in order of the actual contribution percentages, beginning with the highest of such percentages).

Determination of Income. Excess aggregate contributions shall be adjusted for any income or loss. The income or loss allocable to excess contributions allocated to each Participant shall be the income or loss allocable to the Employer matching contributions and, if applicable, Employee after-tax contributions, and such elective deferrals for the Plan Year multiplied by a fraction, the numerator of which is the excess aggregate contributions on behalf of the Participant for the Plan Year, and the denominator of which is the Participant’s Account balance attributable to Employer matching contributions and, if applicable, Employee after-tax contributions, and such elective deferrals (to the extent not used to satisfy the average actual deferral percentage test of Section 10.2) on the last day of the Plan Year.

RULES AND DEFINITIONS

Rules. The following rules shall limit additions to Participants’ Accounts:

If the Participant does not participate, and has never participated, in another qualified plan maintained by the Employer, the amount of annual additions which may be credited to the Participant’s Account for any limitation year shall not exceed the lesser of the “maximum permissible” amount (as hereafter defined) or any other limitation contained in this Plan. If the Employer contribution that would otherwise be allocated to the Participant’s Account would cause the annual additions for the limitation year to exceed the maximum permissible amount, the amount allocated shall be reduced so that the annual additions for the limitation year shall equal the maximum permissible amount.

Prior to determining the Participant’s actual compensation for the limitation year, the Employer may determine the maximum permissible amount for a Participant on the basis of a reasonable estimation of the Participant’s compensation for the limitation year, uniformly determined for all Participants similarly situated.

As soon as is administratively feasible after the end of the limitation year, the maximum permissible amount for the limitation year shall be determined on the basis of the Participant’s actual compensation for the limitation year.

If the limitations of Section 415 of the Code are exceeded, such excess amount shall be corrected in accordance with the requirements of applicable law, including pursuant to the Employee Plans Compliance Resolution System.

If, in addition to this Plan, the Participant is covered under another defined contribution plan maintained by the Employer, or a welfare benefit fund, as defined in Code Section 419(e), maintained by the Employer, or an individual medical account, as defined in Code Section 415(1)(2), maintained by the Employer which provides an annual addition, the annual additions which may be credited to a Participant’s account under all such plans for any such limitation year shall not exceed the maximum permissible amount. Benefits shall be reduced under any discretionary defined contribution plan before they are reduced under any defined contribution pension plan. If both plans are discretionary contribution plans, they shall first be reduced under this Plan. Any excess amount attributable to this Plan shall be disposed of in the manner described in Section 11.1(a)(4).

Definitions.

Annual additions: The following amounts credited to a Participant’s Account for the limitation year shall be treated as annual additions:

Employer contributions;

Elective deferrals (within the meaning of Section 4.1);

Employee after-tax contributions, if any;

Forfeitures, if any; and

Amounts allocated to an individual medical account, as defined in Section 415(l)(2) of the Code, which is part of a pension or annuity plan maintained by the Employer. Also, amounts derived from contributions paid or accrued after December 31, 1985 in taxable years ending after such date which are attributable to post-retirement medical benefits allocated to the separate account of a Key Employee, as defined in Section 419A(d)(3), and amounts under a welfare benefit fund, as defined in Section 419(e), maintained by the Employer, shall be treated as annual additions to a defined contribution plan.

Compensation: For purposes of determining maximum permitted benefits under this Section, compensation shall include all of a Participant’s earned income, wages, differential wage payments as defined by Section 3401(h)(2) of the Code, salaries, and fees for professional services, and other amounts received for personal services actually rendered in the course of employment with the Employer, including, but not limited to, commissions paid to salesmen, compensation for services on the basis of a percentage of profits, commissions on insurance premiums, tips and

Except as provided in the preceding paragraph of this Section 11.1(b)(2), Employer contributions to a plan of deferred compensation which are not included in the Employee’s gross income for the taxable year in which contributed, or Employer contributions under a simplified employee pension plan (funded with individual retirement accounts or annuities) to the extent such contributions are deductible by the Employee, or any distributions from a plan of deferred compensation;

Amounts realized from the exercise of a nonqualified stock option, or when restricted stock (or property) held by the Employee either becomes freely transferable or is no longer subject to a substantial risk of forfeiture;

Amounts realized from the sale, exchange, or other disposition of stock acquired under a qualified stock option;

Other amounts which received special tax benefits, or contributions made by the Employer (whether or not under a salary reduction agreement) toward the purchase of an annuity described in Section 403(b) of the Code (whether or not the amounts are actually excludable from the gross income of the Employee); and

Amounts in excess of the applicable Code Section 401(a)(17) limit.

Defined contribution dollar limitation: This shall mean $40,000, as adjusted under Section 415(d) of the Code.

Employer: For purposes of this Section 11.1, this term refers to the Employer that adopts this Plan, and all members of a controlled group of corporations (as defined in Section 414(b) of the Code, as modified by Section 415(h)), commonly-controlled trades or businesses (as defined in Section 414(c), as modified by Section 415(h)), or affiliated service groups (as defined in Section 414(m)) of which the Employer is a part, or any other entity required to be aggregated with the Employer under Code Section 414(o).

Limitation year: This shall mean the Plan Year, unless the Employer elects a different twelve (12) consecutive month period. The election shall be made by the adoption of a Plan amendment by the Employer. If the limitation year is amended to a different twelve (12) consecutive month period, the new limitation year must begin on a date within the limitation year in which the amendment is made.

Maximum permissible amount: Except to the extent permitted under Section 4.1(e) and Section 414(v) of the Code, if applicable, this shall mean an amount equal to the lesser of the defined contribution dollar limitation or one hundred percent (100%) of the Participant’s compensation for the limitation year. If a short limitation year is created because of an amendment changing the limitation year to a different twelve (12)- consecutive month period, the maximum permissible amount shall not exceed the defined contribution dollar limitation multiplied by the following fraction:

AMENDMENT. The Employer reserves the right to amend, or modify the Plan at any time, or from time to time, in whole or in part. To the extent permitted by board resolutions of the Employer, any amendment may be adopted by action of a named fiduciary appointed pursuant to Section 9.1 to which the Employer as Administrator has delegated the authority to amend the Plan. Any such amendment shall become effective under its terms upon adoption by the Employer, or named fiduciary, as the case may be. However, no amendment affecting the duties, powers or responsibilities of the Trustee may be made without the written consent of the Trustee. No amendment shall be made to the Plan which shall:

make it possible (other than as provided in Section 14.3) for any part of the corpus or income of the Trust Fund (other than such part as may be required to pay taxes and administrative expenses) to be used for or diverted to purposes other than the exclusive benefit of the Participants or their Beneficiaries;

decrease a Participant’s Account balance, or otherwise place greater restrictions or conditions on a Participant’s rights to Section 411(d)(6) protected benefits, even if the amendment merely adds a restriction or condition that is permitted under the vesting rules in Section 411(a)(3) through (11) of the Code;

eliminate an optional form of payment (unless permitted by applicable law) with respect to benefits accrued as of the later of (i) the date such amendment is adopted, or (ii) the date the amendment becomes effective; or

alter the schedule for vesting in a Participant’s Account with respect to any Participant with three (3) or more Years of Service for vesting purposes without his consent or deprive any Participant of any nonforfeitable portion of his Account.

TERMINATION OF THE PLAN. The Employer, by resolution of its board of directors, reserves the right at any time and in its sole discretion to discontinue payments under the Plan and to terminate the Plan. In the event the Plan is terminated, or upon complete discontinuance of contributions under the Plan by the Employer, the rights of each Participant to his Account on the date of such termination or discontinuance of contributions, to the extent of the fair market value under the Trust Fund, shall remain or become fully vested and nonforfeitable. The Employer shall direct the Trustee to distribute the Trust Fund in accordance with the Plan’s distribution provisions to the Participants and their Beneficiaries, each Participant or Beneficiary receiving a portion of the Trust Fund equal to the value of his Account as of the date of distribution. These distributions may be implemented by the continuance of the Trust and the distribution of the Participants’ Account shall be made at such time and in such manner as though the Plan had not terminated, or by any other appropriate method, including rollover into Individual Retirement Accounts. Upon distribution of the Trust Fund, the Trustee shall be discharged from all obligations under the Trust and no Participant or Beneficiary shall have any further right or claim therein. In the event of the partial termination of the Plan, the Accounts of all affected Participants shall remain or become fully vested and nonforfeitable.

TERMINATION OF PARTICIPATION BY PARTICIPATING EMPLOYER. Any Participating Affiliate (within the meaning of Section 1.10) may terminate its participation in the Plan by providing a written resolution to Unitil Corporation. Such Participating Affiliate may request a transfer of Trust assets attributable to its Employees from this Plan to any successor qualified retirement plan maintained by the Participating Affiliate or its successor. The Administrator may, however, refuse to make such transfer if it reasonably believes such transfer would jeopardize the continued qualification of the Plan, or if such transfer does not comply with any requirements of applicable law.

APPLICABILITY. The provisions of this Article shall become applicable only for any Plan Year in which the Plan is a Top-Heavy Plan (as defined in Section 13.2(b)) and only if, and to the extent, required under Section 416 of the Code and the regulations issued thereunder. Notwithstanding the foregoing, this Article shall not apply in any Plan Year in which the Plan consists solely of a cash or deferred arrangement which meets the requirements of Section 401(k)(12) or 401(k)(13) of the Code and matching contributions with respect to which the requirements of Section 401(m)(11) or 401(m)(12) of the Code are met.

DEFINITIONS. For purposes of this Article, the following definitions shall apply:

“Key Employee”: “Key Employee” shall mean any Employee or former Employee (including any deceased Employee) who, at any time during the Plan Year that includes the determination date, was an officer of the Employer having annual compensation greater than $130,000 (as adjusted under Section 416(i)(1) of the Code), a five percent (5%) owner of the Employer, or a one percent (1%) owner of the Employer having annual compensation of more than $150,000. For this purpose, annual compensation shall mean compensation as defined in Section 11.1(b)(2) of the Plan. The determination of who is a Key Employee (including the terms “5% owner” and “1% owner”) shall be made in accordance with Section 416(i)(1) of the Code and the applicable regulations and other guidance of general applicability issued thereunder.

“Top-Heavy Plan”:

The Plan shall constitute a “Top-Heavy Plan” if any of the following conditions exist:

The top-heavy ratio for the Plan exceeds sixty percent (60%) and the Plan is not part of any required aggregation group or permissive aggregation group of plans; or

The Plan is part of a required aggregation group of plans (but is not part of a permissive aggregation group) and the top-heavy ratio for the group of plans exceeds sixty percent (60%); or

The Plan is a part of a required aggregation group of plans and part of a permissive aggregation group and the top-heavy ratio for the permissive aggregation group exceeds sixty percent (60%).

If the Employer maintains one (1) or more defined contribution plans (including any simplified employee pension plan funded with individual retirement accounts or annuities) and the Employer maintains or has

For purposes of (1) and (2) above, the value of account balances and the actuarial equivalents of accrued benefits shall be determined as of the most recent Valuation Date that falls within or ends with the twelve (12)-month period ending on the determination date. The account balances and accrued benefits of a Participant who is not a Key Employee but who was a Key Employee in a prior year shall be disregarded. The accrued benefits and account balances of Participants who have performed no service with any Employer maintaining the plan for the one (1)-year period ending on the determination date shall be disregarded. The calculations of the top-heavy ratio, and the extent to which distributions, rollovers, and transfers are taken into account shall be made under Section 416 of the Code and regulations issued thereunder. Deductible Employee contributions shall not be taken into account for purposes of computing the top-heavy ratio. When aggregating plans, the value of account balances and accrued benefits shall be calculated with reference to the determination dates that fall within the same calendar year.

Definition of terms for Top-Heavy status:

“Top-heavy ratio” shall mean the following:

If the Employer maintains one or more defined contribution plans (including any simplified employee pension plan funded with individual retirement accounts or annuities) and the Employer has never maintained any defined benefitplans which have covered or could cover a Participant in this Plan, the top-heavy ratio is a fraction, the numerator of which is the sum of the account balances of all Key Employees as of the determination date, and the denominator of which is the sum of the account balances of all Participants as of the determination date. Both the numerator and the denominator shall be increased by any contributions due but unpaid to a defined contribution pension plan as of the determination date.

“Permissive aggregation group” shall mean the required aggregation group of plans plus any other plan or plans of the Employer which, when considered as a group with the required aggregation group, would continue to satisfy the requirements of Sections 401(a)(4) and 410 of the Code.

“Required aggregation group” shall mean (i) each qualified plan of the Employer (including any terminated plan) in which at least one Key Employee participates or participated at any time during the Plan Year containing the Determination date or any of the four preceding Plan Years, and (ii) any other qualified plan of the Employer which enables a plan described in (i) to meet the requirements of Section 401(a)(4) or 410 of the Code.

“Determination date” shall mean, for any Plan Year subsequent to the first Plan Year, the last day of the preceding Plan Year. For the first Plan Year of the Plan, “determination date” shall mean the last day of that Plan Year.

“Valuation Date” shall mean the last day of the Plan Year.

Actuarial equivalence shall be based on the interest and mortality rates utilized to determine actuarial equivalence when benefits are paid from any defined benefit plan. If no rates are specified in said plan, the following shall be utilized: pre- and post-retirement interest — five percent (5%); post-retirement mortality based on the Unisex Pension (1984) Table as used by the Pension Benefit Guaranty Corporation on the date of execution hereof.

ALLOCATION OF EMPLOYER CONTRIBUTIONS AND FORFEITURES FOR A TOP-HEAVY PLAN YEAR.

Except as otherwise provided below, in any Plan Year in which the Plan is a Top- Heavy Plan, the Employer contributions and forfeitures allocated on behalf of any Participant who is a non-Key Employee shall not be less than the lesser of three percent (3%) of such Participant’s compensation (as defined in Section 11.1(b)(2) and as limited by Section 401(a)(17) of the Code) or the largest percentage of Employer contributions, elective deferrals (within the meaning of Section 4.1), and forfeitures, as a percentage of the Key Employee’s compensation (as defined in Section 11.1(b)(2) and as limited by Section 401(a)(17) of the Code), allocated on behalf of any Key Employee for that Plan Year. This minimum allocation shall be made even though, under other Plan provisions, the Participant would not otherwise be entitled to receive an allocation or would have received a lesser allocation for the Plan Year because of insufficient Employer contributions under Section 4.2, the Participant’s failure to complete one thousand (1,000) Hours of Service, the Participant’s failure to make elective deferrals under Section 4.1, or compensation is less than a stated amount.

The minimum allocation under this Section shall not apply to any Participant who was not employed by the Employer on the last day of the Plan Year.

Elective deferrals may not be taken into account for the purpose of satisfying the minimum allocation. However, Employer matching contributions may be taken into account for the purpose of satisfying the minimum allocation.

For purposes of the Plan, a non-Key Employee shall be any Employee or Beneficiary of such Employee, any former Employee, or Beneficiary of such former Employee, who is not or was not a Key Employee during the Plan Year ending on the determination date.

If no defined benefit plan has ever been part of a permissive or required aggregation group of plans of the Employer, the contributions and forfeitures under this Section shall be offset by any allocation of contributions and forfeitures under any other defined contribution plan of the Employer with a Plan Year ending in the same calendar year as this Plan’s Valuation Date.

There shall be no duplication of the minimum benefits required under Code Section 416. Benefits shall be provided under defined contribution plans before under defined benefit plans. If a defined benefit plan (active or terminated) is part of the permissive or required aggregation group of plans, the allocation method of subparagraph (a) above shall apply, except that “3%” shall be increased to “5%.”

VESTING. The provisions contained in Section 6.1 relating to vesting shall continue to apply in any Plan Year in which the Plan is a Top-Heavy Plan, and apply to all benefits within the meaning of Section 411(a)(7) of the Code except those attributable to Employee contributions and elective deferrals under Section 4.1, including benefits accrued before the effective date of Section 416 and benefits accrued before the Plan became a Top-Heavy Plan.

PLAN DOES NOT AFFECT EMPLOYMENT. Neither the creation of this Plan, any amendment thereto, the creation of any fund nor the payment of benefits hereunder shall be construed as giving any legal or equitable right to any Employee or Participant against the Employer, or its officers or Employees. All liabilities under this Plan shall be satisfied, if at all, only out of the Trust Fund held by the Trustee. Participation in the Plan shall not give any Participant any right to be retained in the employ of the Employer, and the Employer hereby expressly retains the right to hire and discharge any Employee at any time with or without cause, as if the Plan had not been adopted, and any such discharged Participant shall have only such rights or interests in the Trust Fund as may be specified in the Trust Agreement.

SUCCESSOR TO THE EMPLOYER. In the event of the merger, consolidation, reorganization or sale of assets of the Employer, under circumstances in which a successor person, firm, or corporation shall carry on all or a substantial part of the business of the Employer, and such successor shall employ a substantial number of Employees of the Employer and shall elect to carry on the provisions of the Plan, such successor shall be substituted for the Employer under the terms and provisions of the Plan upon the filing in writing with the Trustee of its election to do so.

REPAYMENTS TO THE EMPLOYER. Notwithstanding any provisions of this Plan to the contrary:

Any monies or other Plan assets attributable to any contribution made to this Plan by the Employer because of a mistake of fact shall be returned to the Employer within one (1) year after the date of contribution.

Any monies or other Plan assets attributable to any contribution made to this Plan by the Employer shall be refunded to the Employer, to the extent such contribution is predicated on the deductibility thereof under the Code and the income tax deduction for such contribution is disallowed. Such amount shall be refunded within one (1) taxable year after the date of such disallowance or within one (1) year of the resolution of any judicial or administrative process with respect to the disallowance. All Employer contributions hereunder are expressly contributed based upon such contributions’ deductibility under the Code.

BENEFITS NOT ASSIGNABLE. Except as provided in Section 414(p) of the Code with respect to “qualified domestic relations orders,” or except as provided in Section 401(a)(13)(C) of the Code with respect to certain judgments and settlements, the rights of any Participant or his Beneficiary to any benefit or payment hereunder shall not be subject to voluntary or involuntary alienation or assignment.

MERGER OF PLANS. In the case of any merger or consolidation of this Plan with, or transfer of the assets or liabilities of the Plan to, any other plan, the terms of such merger, consolidation or transfer shall be such that each Participant would receive (in the event of termination of this Plan or its successor immediately thereafter) a benefit which is no less than what the Participant would have received in the event of termination of this Plan immediately before such merger, consolidation or transfer.

INVESTMENT EXPERIENCE NOT A FORFEITURE. The decrease in value of any Account due to adverse investment experience shall not be considered an impermissible “forfeiture” of any vested balance.

CONSTRUCTION. Wherever appropriate, the use of the masculine gender shall be extended to include the feminine and/or neuter or vice versa; and the singular form of words shall be extended to include the plural; and the plural shall be restricted to mean the singular.

GOVERNING DOCUMENTS. A Participant’s rights shall be determined under the terms of the Plan as in effect at the Participant’s date of termination from employment, or, if later, and to the extent permitted by applicable law, as determined under the terms of the Plan.

GOVERNING LAW. The provisions of this Plan shall be construed under the laws of the state of the situs of the Trust, except to the extent such laws are preempted by Federal law.

HEADINGS. The Article headings and Section numbers are included solely for ease of reference. If there is any conflict between such headings or numbers and the text of the Plan, the text shall control.

COUNTERPARTS. This Plan may be executed in any number of counterparts, each of which shall be deemed an original; said counterparts shall constitute but one and the same instrument, which may be sufficiently evidenced by any one counterpart.

LOCATION OF PARTICIPANT OR BENEFICIARY UNKNOWN. In the event that all or any portion of the distribution payable to a Participant or to a Participant’s Beneficiary hereunder shall, at the expiration of five (5) years after it shall become payable, remain unpaid solely by reason of the inability of the Administrator to ascertain the whereabouts of such Participant or Beneficiary, after sending a registered letter, return receipt requested, to the last known address, and after further diligent effort, the amount so distributable may be forfeited and used to pay Plan administrative expenses and/or used to reduce future Employer contributions. In the event a Participant or Beneficiary is located subsequent to the forfeiture of his Account balance, such Account balance shall be restored.

DISTRIBUTION TO MINOR OR LEGALLY INCAPACITATED. In the event any benefit is payable to a minor or to a person deemed to be incompetent or to a person otherwise under legal disability, or who is by sole reason of advanced age, illness, or other physical or mental incapacity incapable of handling the disposition of his property, the Administrator, may direct the Trustee to make payment of such benefit to the minor’s or legally incapacitated person’s court appointed guardian, person designated in a valid power of attorney, or any other person authorized under state law. The receipt of any such payment or distribution shall be a complete discharge of liability for Plan obligations.

CORRECTIVE ACTION. The Administrator with the Employer’s consent and approval, may correct mistakes in distributions or crediting amounts to Accounts or pursuant to a settlement or judgement awarding back pay, or such other matters as may be appropriate. The Employer may, in Employer’s sole discretion, elect to make special contributions to the Plan in order to correct such mistakes. Any such contribution shall be allocated as specified by the Administrator.

ERRONEOUS PAYMENTS. If any person receives any amount of benefits that the Administrator in its sole discretion later determines that such person was not entitled to receive under the terms of the Plan, the Administrator shall have the right to require such person to make reimbursement to the Plan and/or to offset or adjust any future claims for benefits under the Plan against amounts that such person was not otherwise entitled to receive.

COMPLIANCE WITH SECTION 410. Notwithstanding the foregoing provisions, if, for any Plan Year, the requirements of Code Section 410(b) are not satisfied, the Plan Administrator may take such action as is necessary to bring the Plan into compliance with such Code Section, including, without limitation, specifying that additional individual(s) are also entitled to share in the allocation process.

PROVISION REGARDING CONFLICTING TRUST PROVISIONS. The provisions of the Plan shall govern and override any conflicting provision contained in the Trust Agreement or, if applicable, custody agreement used in connection with the Plan.

STATUS OF PLAN. The Plan is based on a pre-approved defined contribution with a cash or deferred arrangement (“Pre-Approved Plan”) sponsored by John Hancock Retirement Plan Services, LLC (“Pre-Approved Plan Provider”). The Plan has been approved by the Internal Revenue Service for which an opinion letter (“IRS Opinion Letter”) has been issued. The failure to properly complete the Plan provisions may result in failure of the Plan to qualify under Section 401(a) of the Code. Questions regarding the adoption of the pre-approved plan, the meaning of Plan provisions, or the effect of the IRS Opinion Letter should be directed to John Hancock Retirement Plan Services LLC, 200 Berkeley Street, Boston, MA 02116, Attention: Pre-Approved Defined Contribution Plan Coordinator; phone number: (800) 294-3575.

AMENDMENT AUTHORITY. The Pre-Approved Plan Provider may amend or restate the Pre-Approved Plan to ensure continued compliance with the qualification requirements of Section 401(a) of the Code, including any correction of prior pre-approved plans and to reflect changes in the Code, related Treasury Regulations and other guidance issued in the Internal Revenue Bulletin. Any such amendments or restatement must first be approved by the Internal Revenue Service, unless approval is not required due to the nature of the change or provisions of the pre-approved document program.

LIMITATIONS ON EMPLOYER RELIANCE ON OPINION LETTER. An Employer that adopts the Pre-Approved Plan shall be able to rely on the IRS Opinion Letter issued for the Pre-Approved Plan as to the qualification in form of the Pre-Approved Plan under Section 401(a) of the Code, to the extent provided in Revenue Procedure 2017-41. The Adopting Employer may not rely on the opinion letter in certain circumstances or with respect to certain qualification requirements outlined in the IRS Opinion Letter and in Revenue Procedure 2017-41.
