The first June 1 – June 30 annual election period for a newly eligible 401(a)(17) Participant shall be the June 1 – June 30 of the Plan Year following the Plan Year in which the 30-day period set forth in subsection (d) below expires (unless such 30-day period spans two Plan Years and the Participant makes his or her initial election to defer Compensation in the first Plan Year, in which case his or her first annual election period shall be the June 1 – June 30 of the Plan Year following the Plan Year in which the election is made).

(c)    For the Plan Year beginning January 1, 2014, a 401(a)(17) Participant on or before September 30, 2013 may elect to defer up to: (i) 50% of his or her Compensation (other than Performance Based Compensation) payable for services to be performed in such year, and (ii) 50% of the portion of his or her Performance Based Compensation payable in such year that may be taken into account under this Plan (i.e., 25%), and the percentage elected (from 1% to 50%) must be the same for Compensation described in clauses (i) and (ii). Such election shall be made from September 1, 2013, until September 30, 2013.

An election during the 30-day period to defer Compensation shall, with respect to Performance Based Compensation payable in the Plan Year following the Plan Year in which the election is made, apply to only a portion of such compensation determined in accordance with the following schedule:

Calendar Quarter in                 Portion of Performance

April 1 – June 30                    50%

In the event a Participant receives a hardship distribution from the Qualified Plan, his or her election to defer Compensation under this Plan shall be cancelled for a period of 6 months beginning immediately after he or she receives the hardship distribution (or for the remainder of the Plan Year in which the hardship distribution is made, if longer).

(f)    Notwithstanding any other provision of the Plan, an election to defer Compensation pursuant to subsection (b) or modification of an election to defer Compensation pursuant to subsection (e) shall be effective with respect to Performance Based Compensation payable in the Plan Year following the Plan Year in which the election or modification is made only if the Participant has performed services continuously from the later of the beginning of the performance period or the date the performance criteria are established through the date his or her election or modification is made, and the election or modification is made before such Performance Based Compensation is readily ascertainable within the meaning of Treasury Regulation § 1.409A-2(a)(8).

2.2    Matching Deferrals. For each payroll period, each Employer shall make matching deferrals on behalf of each 401(a)(17) Participant in its employ who defers Compensation under Section 2.1 for such year and who has completed one Year of Participation Service. Matching deferrals shall be made at the rate of $1.00 for each dollar of Compensation deferred under Section 2.1 with respect to payroll periods beginning on or after the date the Participant completes one Year of Participation Service, up to 5% of his or her Compensation for such payroll periods.

2.3    Nonelective Deferrals. For each payroll period, each Employer shall make nonelective deferrals on behalf of each 401(a)(17) Participant in its employ who has completed one Year of Participation Service in an amount equal to 4.5% of his or her Compensation for such payroll period, beginning with the first payroll period that coincides with or next follows the date he or she completes one Year of Participation Service; provided, with respect to the Plan Year in which the Participant first completes one Year of Service, the amount of nonelective deferrals to be made in accordance with this Section 2.3 for any payroll period shall be reduced by the amount of any nonelective contributions made on such Participant’s behalf under Section 3.10 of the Qualified Plan for such payroll period.

2.4    Nonelective Transition Deferrals. For each payroll period beginning on or after January 1, 2014 and beginning on or before December 31, 2020, each Employer shall make nonelective transition deferrals on behalf of each 401(a)(17) Participant in its employ who meets the requirements of this Section in an amount equal to 7% of his or her Compensation for such payroll period (such percentage having been determined with reference to the design of the Qualified Plan, under which transition contributions are made on behalf of eligible participants in an amount equal to the sum of (i) 3.5% of their compensation as defined in such plan and (ii) 3.5% of the amount of their compensation as so defined in excess of $70,000; and Compensation herein being amounts in excess of the annual limit under Code Section 401(a)(17)). A Participant meets the requirements of this Section if:

(a)    he or she is an active Employee on January 1, 2014; and

(b)    as of December 31, 2013:

(i)    the sum of his or her years of age (rounded down to the nearest whole number) and years of vesting service (rounded down to the nearest whole number) is at least 60, and he or she is credited with at least 15 years of vesting service; or

(ii)    he or she is credited with at least 10 years of vesting service and has attained age 50.

For purposes of this Section, a “year of vesting service” means a year of vesting service as defined in the Unum Group Pension Plan.

2.5    Deferrals of Amounts that Exceed Code Section 415 Limit. For each payroll period beginning on or after January 1, 2014 and beginning on or before December 31, 2020, each Employer shall make deferrals on behalf of each 415 Spillover Participant in its employ in an amount equal to the contributions that would have been made on his or her behalf under the Qualified Plan for such payroll period but for the limit on annual additions under Code Section 415. In the event a Participant receives a hardship distribution from the Qualified Plan, amounts to be deferred under this Section consisting of the elective contributions (and matching contributions) that would have been made on his or her behalf under the Qualified Plan shall be cancelled for a period of 6 months

beginning immediately after he or she receives the hardship distribution (or for the remainder of the Plan Year in which the hardship distribution is made, if longer).

2.6    Vesting. All amounts deferred under this Plan shall be fully vested and nonforfeitable.

2.7    Death Benefits. In the event of a Participant's death, his or her Account shall be paid in accordance with the provisions of Section 4.3.

3.1    Accounts. The Company (or its designated agent) shall establish an Account for each Participant and shall adjust such account as of each Valuation Date as follows:

(a)    First, determine the fair market value of each Investment Fund as of the close of business on such date.

(b)    Second, allocate the notional income, expenses, gains and losses of each Investment Fund among the Accounts in proportion to the Account balances (to the extent deemed invested therein) as of the close of business on the preceding Valuation Date.

(c)    Third, reduce the separate Account of each Participant to reflect all deemed distributions made from such Account since the preceding Valuation Date.

(d)    Fourth, credit to the separate Account of each Participant the deferrals made on his or her behalf under Article II since the preceding Valuation Date.

(e)    Fifth, adjust each Participant’s Account to reflect deemed transfers among the Investment Funds, if any.

A Participant’s Account shall continue to be adjusted for notional investment experience until all amounts credited to the Account have been distributed in accordance with Article IV.

3.2    Participant Investment Directions. Each Participant may direct that deferrals made on his or her behalf under this Plan shall be deemed invested in any one or more of the Investment Funds; provided the percentage of deferrals to be deemed invested in any Investment Fund shall be 1%, or a multiple thereof. An investment direction shall be made by such written, telephonic or electronic means as shall be prescribed by the Plan Administrator.

A Participant’s investment direction, if received by the Plan Administrator (or its designated agent) prior to the date he or she commences participation, shall be effective as of said date. If a Participant does not make an investment direction or an investment direction is not received by the Plan Administrator (or its designated agent) before the Participant commences participation, the deferrals made on behalf of such Participant shall be deemed invested in the Investment Fund designated by the Company or its delegate for such purpose. An investment direction received by

the Plan Administrator (or its designated agent) after the date a Participant commences participation shall be effective as soon as practicable after receipt by the Plan Administrator (or its designated agent).

A Participant may modify at any time an investment direction to have future deferrals made on his or her behalf under the Plan deemed invested in the Investment Funds in proportions other than those previously elected. An election modifying a previous investment direction shall be made in multiples of 1% of such deferrals and shall be made by such written, telephonic or electronic means as shall be prescribed by the Plan Administrator. A modification shall be effective as soon as practicable after receipt by the Plan Administrator (or its designated agent), subject to any restrictions set forth in the prospectus for the applicable Investment Fund.

Subject to such restrictions under any other agreement as may apply with respect to transfers between competing Investment Funds, a Participant, his or her surviving spouse or Beneficiary, as the case may be, may elect at any time a deemed reinvestment of all or a portion of the balance of his or her Account in any one or more of the Investment Funds. An election to reinvest all or a portion of an Account balance shall be made in 1% multiples of such balance, specified dollar amounts or specified number of shares/units (as specified by the Participant, or his or her surviving spouse or Beneficiary) and shall be made by such written, telephonic or electronic means as shall be prescribed by the Plan Administrator. An election to reinvest all or a portion of an Account balance shall be effective as soon as practicable after receipt by the Plan Administrator (or its designated agent).

The Company or its delegate may from time to time add or eliminate Investment Funds. Whenever an Investment Fund is eliminated, the portion of Participants’ Accounts deemed invested therein shall be deemed reinvested in such other Investment Fund as the Company or its delegate may direct, unless a Participant, surviving spouse or Beneficiary, pursuant to this Section, elects the deemed reinvestment of all or a portion of the balance of his or her Account which had been invested in the eliminated Investment Fund in one or more of the other available Investment Funds.

4.1    Time of Distribution to Participants.

(a)    Except as provided in subsection (b), Section 4.2 or Section 4.6, distribution of a Participant’s Account to the Participant shall be made or commence as soon as administratively practicable following the date determined in accordance with (i) or (ii) below, whichever is applicable:

(i)    If the Participant made an effective transition election pursuant to Section 3.04 of the Unum Group Supplemental Pension Plan, the date determined in accordance with such election; or

(ii)    For any other Participant, the later of the date on which he or she attains age 60 and the date on which he or she Terminates Employment.

        

(b)    Notwithstanding any other provision of the Plan to the contrary, in the case of a Participant who is a Key Employee on his or her Termination of Employment date, distribution shall be made or commence as of the later of: (i) the date distribution otherwise would be made or commence without regard to this subsection (b), and (ii) the 6-month anniversary of the Participant’s Termination of Employment date or, if earlier, the Participant’s date of death.

4.2    Distribution upon becoming Disabled. In the event a Participant becomes Disabled, he or she may request that distribution of his or her Account be made or commence as soon as administratively practicable thereafter; provided, however, if a Participant is a Key Employee on his or her Termination of Employment Date and becomes Disabled after such date, distribution may not be made or commence prior to the date determined under Section 4.1(b)(ii).

4.3    Distribution upon Death. In the event a Participant dies before distribution of his or her Account has been made or commenced, his or her Account shall be distributed to his or her surviving spouse, or, if the Participant is not survived by a spouse or the Participant’s spouse consents in the manner provided below, to his or her Beneficiary, as soon as administratively practicable after the date of the Participant’s death in the form determined in accordance with Section 4.5.

In the event a Participant dies after distribution of his or her Account has commenced but before all payments have been made, the remaining Account balance shall continue to be distributed to his or her surviving spouse, or, if the Participant is not survived by a spouse or the Participant’s spouse consents in the manner provided below, to his or her Beneficiary, in accordance with the form of distribution in effect as of the Participant’s date of death.

To be effective, the consent of a Participant’s surviving spouse to the Participant’s designated Beneficiary must meet the requirements set forth in Section 9.3 of the Qualified Plan; provided no spousal consent shall be required to designate a nonspouse Beneficiary under the circumstances described in Section 9.3 of the Qualified Plan.

Subject to the preceding provisions of this Section, each Participant from time to time may designate any person or persons (who may be designated concurrently, contingently or successively) to receive any benefits payable upon his or her death. Each Beneficiary designation shall revoke all prior designations by the Participant and shall be effective only when filed with the Plan Administrator (or its designated agent) during the Participant’s lifetime by such written, telephonic or electronic means as shall be prescribed by the Plan Administrator. If a Participant fails to designate a Beneficiary, distribution shall be made to the person(s) and in the order determined in accordance with the provisions of Section 9.3 of the Qualified Plan.

4.4    Distribution pursuant to Domestic Relations Order. Distribution of a Participant’s Account under the Plan shall be subject to the terms of any domestic relations order with respect to the Participant that the Plan Administrator (or its designated agent for such purpose) determines

would be a qualified domestic relations order within the meaning of Code Section 414(p) if this Plan were a tax-qualified retirement plan, including any such order that accelerates the time or schedule of a payment under the Plan.

4.5    Form of Distribution. A 401(a)(17) Participant may elect that distribution of his or her Account be made in one of the following forms:

(a)    a single lump sum;

(b)    annual, equal installments over 5 calendar years; or

(c)    annual, equal installments over 10 calendar years.

The amount of each installment shall be calculated by multiplying the current balance of the Participant’s Account by a fraction, the numerator of which is one and the denominator of which is the number of installments remaining to be paid.

A 401(a)(17) Participant’s election shall be made by such written, telephonic or electronic means as shall be prescribed by the Plan Administrator, shall be irrevocable as of the last day of the applicable election period, and shall apply to the Participant’s entire Account; provided, however, if any amount deferred under Section 2.5 was credited to the Participant’s Account before the date of his or her election under this Section, the election shall not apply to the portion of his or her Account that is attributable to all amounts deferred under Section 2.5, and such portion of the Participant’s Account shall be paid in a single lump sum.

In the case of a 401(a)(17) Participant on or before September 30, 2013, such election shall be made from September 1, 2013, until September 30, 2013. In the case of any other 401(a)(17) Participant, such election shall be made within 30 days after he or she becomes a 401(a)(17) Participant. If a 401(a)(17) Participant fails to elect a form of distribution within the prescribed time, his or her entire Account shall be distributed in a single lump sum.

Distribution of the Account of a 415 Spillover Participant who is not also a 401(a)(17) Participant shall be made in a single lump sum.

All distributions shall be made in cash.

4.6    Cashouts. Notwithstanding any other provision of the Plan to the contrary, if the value of a Participant’s Account does not exceed $15,000 as of the administrative processing date, such Account shall be paid in the form of a single lump sum payment as soon as administratively practicable after such date; provided, however, in the case of Termination of Employment of a Participant who is a Key Employee, payment shall be made as soon as administratively practicable after the 6-month anniversary of the Participant’s Termination of Employment date (or, if earlier, the Participant’s date of death). For this purpose, the Participant’s Account shall mean his or her entire interest under this Plan and all other agreements, methods, programs or other arrangements required to be aggregated with this Plan under Treasury Regulation § 1.409A-1(c)(2).

“Administrative processing date” shall mean the Valuation Date as of which the Plan Administrator (or its designated agent), in the normal course, is notified by the Company of the Participant’s Termination of Employment or death.

4.7    Other Limitations. No Plan loans to or hardship withdrawals by Participants shall be permitted.

5.1    Allocation of Responsibility. The Plan Administrator shall be responsible for and shall have complete discretionary authority to control and manage the operation and administration of the Plan and to interpret and construe Plan provisions, including determining eligibility for benefits, and his or her final decision on appeal shall not be disturbed except upon judicial determination of abuse of discretion.

Subject to the provisions of this Plan, the Plan Administrator from time to time may establish rules for the administration and interpretation of the Plan. All actions, decisions and interpretations of the Plan Administrator shall be made in a uniform and nondiscriminatory manner.

5.2    Claims Procedure.

(ii)     shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant to the claim for benefits.

The Plan Administrator’s review of any adverse benefit determination shall take into account all comments, documents, records and other information submitted by the claimant or his or her authorized representative relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination.

(c)    The Plan Administrator shall provide the claimant with written or electronic notification of the benefit determination on review not later than 60 days after receipt of a request for review, unless special circumstances require an extension of time for processing. If an extension of time for processing is required, the Plan Administrator shall, prior to the termination of the initial 60-day period, furnish the claimant with written notice indicating the special circumstances requiring an extension of time and the date by which the Plan Administrator expects to render the determination on review. In no event shall such extension exceed a period of 60 days from the end of the initial 60-day period.

In the case of an adverse benefit determination, the notification shall set forth in a manner calculated to be understood by the claimant:

(i)    the specific reason or reasons for the adverse determination;

(ii)    reference to the specific Plan provisions on which the determination is based;

(iii)    a statement that the claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant to the claimant’s claim for benefits; and

(iv)    a statement of the claimant’s right to bring a civil action under Section 502(a) of ERISA.

(d)    Notwithstanding the foregoing provisions to the contrary, a claim for benefits based on the Participant becoming Disabled shall be made and processed in accordance with the claims procedures under the Unum Group Employees Long-Term Disability Plan.

(e)    Before pursuing a legal remedy, a claimant shall first exhaust all claims, review and appeals procedures under the Plan. A claimant may bring a legal action against the Plan, Unum Group or any other Employer, the Board, the Plan Administrator, or any other person, or the employees or agents of these entities, only in the United States District Court in Portland, Maine or Chattanooga, Tennessee. Such legal action may not be brought more than one year after the final disposition of the claim under this Section. The agent for service of legal process on the Plan shall be:

Vice President, Employment Law

Unum Group

1 Fountain Square

Chattanooga, TN 37402

5.3    Agents. The Plan Administrator may employ counsel and other agents, may delegate ministerial duties to such agents or to employees of the Company and may procure such clerical, accounting, consulting and other services as it may require in carrying out the provisions of the Plan.

5.4    Indemnification. To the extent permitted by applicable law, the Company and the other Employers shall indemnify and save harmless the Plan Administrator against all expenses and liabilities arising out of his or her acts or omissions with respect to the Plan, provided he or she would be entitled to indemnification pursuant to the bylaws of the Company or the affected Employer, as the case may be.

6.1    Reemployed Former 401(a)(17) Participant. In the event a 401(a)(17) Participant Terminates Employment, begins receiving distribution of his or her Account in the form of installments, and becomes reemployed by an Employer or Affiliate prior to the date the last installment payment is to be made, payment of the portion of his or her Account attributable to

amounts deferred before such termination shall continue to be made in accordance with his or her election under Section 4.5.

A 401(a)(17) Participant who is reemployed by an Employer shall be treated as a newly eligible 401(a)(17) Participant as of the date he or she again becomes a 401(a)(17) Participant, for purposes of electing to defer Compensation pursuant to Section 2.1 and electing the form of distribution of the portion of his or her Account that is attributable to amounts deferred after his or her reemployment date, if he or she is described in (a) or (b) below:

(a)    the Participant has been paid all amounts deferred under the Plan and on or before the date of the last payment was not eligible to continue (or elect to continue) to participate in the Plan; or

(b)    regardless of whether all amounts deferred under the Plan have been paid, the Participant has not been eligible to participate in the Plan (other than the accrual of earnings) at any time during the 24-month period ending on the date he or she again becomes a 401(a)(17) Participant.

A 401(a)(17) Participant who is reemployed by an Employer but who is not described in (a) or (b) above may not elect to defer Compensation pursuant to Section 2.1 until the first June 1 – June 30 annual election period following his or her reemployment date (or the June 1 – June 30 annual election period in which his or her reemployment date occurs, if earlier), and such election shall be effective with respect to (1) Compensation (other than Performance Based Compensation) payable for services to be performed in the Plan Year next following such annual election period; and (2) Performance Based Compensation payable in the Plan Year next following such annual election period, subject to Section 2.1(f). Payment of the portion of such 401(a)(17) Participant’s Account that is attributable to amounts deferred after his or her reemployment date shall be made in the same form as payment of the portion of his or her Account that is attributable to amounts deferred prior to his or her Termination of Employment.

6.2    Amendment and Termination. The Board may at any time, in its sole discretion, terminate this Plan or amend this Plan in whole or in part. No such termination or amendment shall affect the right of any Participant, his or her surviving spouse or Beneficiary, as the case may be, to receive or continue to receive a benefit under the terms of this Plan on the date immediately preceding such termination or amendment. In the event the Plan is terminated, Participants’ Accounts shall be distributed at such time and in such form as shall comply with the requirements of Code Section 409A and related regulations.

6.3    Delegation by Participating Employers. Each Affiliate that adopts the Plan hereby irrevocably grants to the Company, the Board and the Plan Administrator the exclusive authority to exercise all of the powers conferred on them by the terms of the Plan, including the power vested in the Board to amend the Plan and the power vested in the Board to terminate the Plan, and hereby appoints the Company, the Board and the Plan Administrator as its agents for such purposes. In addition, each Affiliate that adopts the Plan shall, to the extent not assumed by the Company, accept

the obligations and responsibilities otherwise imposed on the Company by the terms of the Plan with respect to any Participant who is its Employee without further action on its part.

6.4    Employee Status. Nothing contained herein will confer upon any Participant the right to be retained in the service of the Company and its Affiliates or any other right not expressly provided for herein, nor will the existence of this Plan impair the right of the Company and its Affiliates to discharge or otherwise deal with a Participant.

6.5    Funding. This Plan is unfunded for purposes of the Code and Title I of ERISA and is not intended to meet the requirements of Code Section 401(a). The Plan constitutes a mere promise by the Company and the other Employers to pay benefits in the future, and a Participant hereunder shall have no greater rights than a general, unsecured creditor of the Company and the other Employers. The Company and each other Employer shall be solely responsible for the payment of benefits with respect to its own Employees who are Participants in the Plan.

6.6    Assignment. To the maximum extent permitted by law, no benefit under this Plan shall be assignable or subject in any manner to alienation, sale, transfer, claims of creditors, pledge, attachment or encumbrances of any kind.

6.7    Taxes. Any and all taxes that may be due and owing with respect to any payment under the Plan shall be the sole responsibility of the persons to whom and for whose benefit such payment is made; provided, however, the Company and each other Employer, as applicable (or their designated agents), shall withhold from any payment made under the Plan all amounts that are required by law to be withheld.

6.8    Governing Law. This Plan is established under and will be construed according to the laws of the State of Tennessee without regard to any conflict of law principles, except to the extent such laws may be preempted by ERISA.

6.9    Compliance with Code Section 409A. The terms of the Plan shall be interpreted and applied in a manner consistent with the requirements of Section 409A of the Code and the final regulations thereunder. The Employers shall have no obligation to reimburse a Participant for any tax penalty or interest payable under Section 409A of the Code.
