Form of Change in Control Severance Agreement, as amended




 Exhibit 10.8 
 UNUM GROUP 
 CHANGE IN CONTROL SEVERANCE AGREEMENT 
         AGREEMENT by and between Unum Group, a Delaware corporation having its principal executive offices in
Chattanooga, Tennessee (the “Company”), and [                    ] (the “Executive”), dated as of the
[        ] day of [            ], 200[        ]. 
         The Company has determined that it is in the best interests of its shareholders to provide the Company
with continuity of management, including the continued dedication of the Executive. Therefore, in order to accomplish these objectives, the Executive and the Company desire to enter into this Agreement. 
         NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS: 
         1.        Effective Date.   The “Effective
Date” shall mean [                    ], provided the Executive is employed by the Company on such date. 
         2.        Term of Agreement.   The Company
hereby agrees that the term of this Agreement shall be for the period commencing on the Effective Date and ending on the second anniversary of the Effective Date (the “Initial Term”). Beginning on the second anniversary of the Effective
Date, the Initial Term shall be automatically extended for one year terms unless either the Company or the Executive shall give the other party, not less than 90 days prior to such Renewal Date, written notice that the Agreement shall not be so
extended. 
         3.        Termination of
Employment. 
                 (a)        Death or Disability.   The Executive’s employment shall terminate
automatically upon the Executive’s death. If the Company determines in good faith that the Disability of the Executive has occurred (pursuant to the definition of Disability set forth below), it may give to the Executive written notice in
accordance with Section 10(b) of this Agreement of its intention to terminate the Executive’s employment. In such event, the Executive’s employment with the Company shall terminate effective on the 30th day after receipt of such
notice by the Executive (the “Disability Effective Date”), provided that, within the 30 days after such receipt, the Executive shall not have returned to full-time performance of the Executive’s duties. For purposes of this Agreement,
“Disability” shall mean the absence of the Executive from the Executive’s duties with the Company on a full time basis for 180 business days during any consecutive twelve-month period as a result of incapacity due to mental or
physical illness which is determined to be total and permanent by a physician selected by the Company or its insurers and acceptable to the Executive or the Executive’s legal representative. 
                 (b)        Cause.   The Company may terminate the Executive’s employment for
Cause. For purposes of this Agreement, “Cause” shall mean: 
                         (i)        the continued failure of the Executive to
perform substantially the Executive’s duties with the Company or one of its affiliates (other than 

  

 1 









 
any such failure resulting from incapacity due to physical or mental illness), after a written demand for substantial performance is delivered to the
Executive by the Chief Executive Officer of the Company (“CEO”) which specifically identifies the manner in which the CEO believes that the Executive has not substantially performed the Executive’s duties, or 
                 (ii)        the willful engaging by the Executive in illegal conduct (as determined by the Company after
due inquiry) or gross misconduct which is materially and demonstrably injurious to the Company, or 
                 (iii)        conviction of a felony or guilty or nolo contendere plea by the Executive with respect
thereto. 
 For purposes of this provision, no act or failure to act, on the part of the Executive, shall be considered “willful” unless it is
done, or omitted to be done, by the Executive in bad faith or without reasonable belief that the Executive’s action or omission was in the best interests of the Company. Any act, or failure to act, based upon authority given pursuant to a
resolution duly adopted by the Board or upon the instructions of the CEO or based upon the advice of counsel for the Company shall be conclusively presumed to be done, or omitted to be done, by the Executive in good faith and in the best interests
of the Company. The cessation of employment of the Executive shall not be deemed to be for Cause unless and until there shall have been delivered to the Executive written notice signed by the CEO of the Company of an event constituting cause within
90 days of the Company’s knowledge of its existence. 
         (c)        Good Reason.   The Executive’s employment may be terminated by the Executive for Good Reason. In order to invoke a
termination for Good Reason, the Executive shall provide written notice to the Company of one or more of the conditions described in clauses (i) through (vii) below within 90 days following the Executive’s knowledge of the initial
existence of such condition, specifying in reasonable detail the conditions constituting Good Reason, and the Company shall have 30 days following receipt of such written notice (the “Cure Period”) during which it may remedy the condition.
In the event that the Company fails to remedy the condition constituting Good Reason during the applicable Cure Period, the Executive’s “separation from service” (within the meaning of Section 409A of the Internal Revenue Code of
1986, as amended (the “Code”)) must occur, if at all, within 2 years following such Cure Period in order for such termination as a result of such condition to constitute a termination for Good Reason. For purposes of this Agreement,
“Good Reason” shall mean: 
                 (i)        the assignment to the Executive of any duties materially inconsistent with the
Executive’s position (including status, offices, titles and reporting requirements), authority, duties or responsibilities, or any other action by the Company which results in a material diminution in the Executive’s authority, duties or
responsibilities, or the budget over which the Executive retains authority, excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith; 
  

 2 









                 (ii)         a material reduction in the Executive’s annual base salary or annual target bonus
as in effect prior to a Change in Control; 
                 (iii)        the failure of the Company to (A) continue in effect any material employee benefit
plan, compensation plan, welfare benefit plan or fringe benefit plan in which the Executive is participating immediately prior to such Change in Control or the taking of any action by the Company which would materially and adversely affect the
Executive’s participation in or materially reduce the Executive’s benefits under any such plan, unless Executive is permitted to participate in other plans providing the Executive with materially equivalent benefits in the aggregate (at
materially equivalent cost with respect to welfare benefit plans), or (B) provide the Executive with paid vacation materially similar to that provided by the most favorable vacation policies of the Company as in effect for the Executive
immediately prior to such Change in Control, including the crediting of all service for which the Executive had been credited under such vacation policies prior to the Change in Control; 
                 (iv)        any material failure by the Company to comply with and satisfy Section 9(c) of this
Agreement; 
                 (v)         any required relocation of the Executive following a Change in Control (as defined
herein) of more than 50 miles from Executive’s principal business office as of immediately prior to the Effective Date; 
                 (vi)        any other action or inaction that constitutes a material breach by the Company of any
agreement under which the Executive provides services to the Company; or 
                 (vii)        any material diminution in the authority, duties, or responsibilities of those to whom the
Executive is required to report. 
         (d)        Change in Control.   For purposes of this Agreement, “Change in Control” shall mean the occurrence of any one of
the following events and shall not include the merger of Unum Corporation and Provident Companies, Inc. pursuant to the Agreement and Plan of Merger dated as of November 22, 1998 as amended as of May 25, 1999 and consummated on
June 30, 1999: 
                 (i)          during any period of 2 consecutive years, individuals who, at the beginning of
such period, constitute the Board (the “Incumbent Directors”) cease for any reason to constitute at least a majority of the Board, provided that any person becoming a director and whose election or nomination for election was approved by a
vote of at least two-thirds of the Incumbent Directors then on the Board (either by a specific vote or by approval of the proxy statement of the Company in which such person is named as a nominee for director, without written objection to such
nomination) shall be an Incumbent Director; provided, however, that no individual initially elected or nominated as a director of the Company as a result of an actual or threatened election 

  

 3 









 
contest (as described in Rule 14a-11 under the Securities Exchange Act of 1934 (the “Act”)) (“Election Contest”) or other actual or
threatened solicitation of proxies or consents by or on behalf of any “person” (as such term is defined in Section 3(a)(9) of the Act and as used in Sections 13(d)(3) and 14(d)(2) of the Act) other than the Board (“Proxy
Contest”), including by reason of any agreement intended to avoid or settle any Election or Contest or Proxy Contest, shall be deemed an Incumbent Director; 
                 (ii)        any person is or becomes a “beneficial owner” (as defined in Rule 13d-3 under the
Act), directly or indirectly, of securities of the Company representing 20% (30% with respect to deferred compensation subject to Section 409A of the Code) or more of the combined voting power of the Company’s then outstanding securities
eligible to vote for the election of the Board (the “Company Voting Securities”); provided, however, that the event described in this paragraph (ii) shall not be deemed to be a Change in Control of the Company by virtue
of any of the following acquisitions: (A) by the Company of any subsidiary, (B) by any employee benefit plan (or related trust) sponsored or maintained by the Company or any subsidiary, (C) by an underwriter temporarily holding
securities pursuant to an offering of such securities, (D) pursuant to a Non-Qualifying Transaction (as defined in paragraph (iii)), or (E) a transaction (other than one described in (iii) below) in which Company Voting Securities are
acquired from the Company, if a majority of the Incumbent Directors approve a resolution providing expressly that the acquisition pursuant to this clause (E) does not constitute a Change in Control of the Company under this paragraph (ii);

                 (iii)        the consummation of a merger, consolidation, statutory share exchange or similar form of
corporate transaction involving the Company or any of its subsidiaries that requires the approval of the Company’s stockholders, whether for such transaction or the issuance of securities in the transaction (a “Reorganization”), or
sale or other disposition of all or substantially all of the Company’s assets to an entity that is not an affiliate of the Company (a “Sale”), unless immediately following such Reorganization or Sale: (A) more than 50% of the
total voting power of (x) the corporation resulting from such Reorganization or the corporation which has acquired all or substantially all of the assets of the Company (in either case, the “Surviving Corporation”), or (y) if
applicable, the ultimate parent corporation that directly or indirectly has beneficial ownership of 100% of the voting securities eligible to elect directors of the Surviving Corporation (the “Parent Corporation”), is represented by the
Company Voting Securities that were outstanding immediately prior to such Reorganization or Sale (or, if applicable, is represented by shares into which such Company Voting Securities were converted pursuant to such Reorganization or Sale), and such
voting power among the holders thereof is in substantially the same proportion as the voting power of such Company Voting Securities among the holders thereof immediately prior to the Reorganization or Sale, (B) no person (other than any
employee benefit plan (or related trust) sponsored or maintained by the Surviving Corporation or the Parent Corporation) is or becomes the beneficial owner, directly or indirectly, of 20% (30% with respect to deferred compensation subject to
Section 409A of the Code) or more of the total voting power of the outstanding voting securities eligible to elect 

  

 4 









 
directors of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation) and (C) at least a majority of the members of the
board of directors of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation) following the consummation of the Reorganization or Sale were Incumbent Directors at the time of the Board’s approval of the
execution of the initial agreement providing for such Reorganization or Sale (any Reorganization or Sale which satisfies all of the criteria specified in (A), (B) and (C) above shall be deemed to be a “Non-Qualifying
Transaction”); or 
                 (iv)        the stockholders of the Company approve a plan of complete liquidation or dissolution of the
Company. 
 Notwithstanding the foregoing, a Change in Control of the Company shall not be deemed to occur solely because any person acquires beneficial
ownership of more than 20% (30% with respect to deferred compensation subject to Section 409A of the Code) of the Company Voting Securities as a result of the acquisition of Company Voting Securities by the Company which reduces the number of
Company Voting Securities outstanding; provided, that if after such acquisition by the Company such person becomes the beneficial owner of additional Company Voting Securities that increases the percentage of outstanding Company Voting
Securities beneficially owned by such person, a Change in Control of the Company shall then occur. 
                 (e)          Notice of Termination. Any termination by the Company or by the Executive shall
be communicated by Notice of Termination to the other party hereto given in accordance with Section 11(b) of this Agreement. For purposes of this Agreement, a “Notice of Termination” means a written notice which (i) indicates the
specific termination provision in this Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment under the
provision so indicated and (iii) if the Date of Termination (as defined below) is other than the date of receipt of such notice, specifies the termination date (which date shall be not more than 30 days after the giving of such notice). The
failure by the Executive or the Company to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive any right of the Executive or the Company, respectively, hereunder or
preclude the Executive or the Company, respectively, from asserting such fact or circumstance in enforcing the Executive’s or the Company’s rights hereunder. 
                 (f)         Date of Termination. “Date of Termination”
means (i) if the Executive’s employment is terminated by the Company other than for Disability, or by the Executive, the date of receipt of the Notice of Termination or any later date specified therein within 30 days of such notice, or
(ii) if the Executive’s employment is terminated by reason of death or Disability, the date of death of the Executive or the Disability Effective Date, as the case may be. 
         4.      Obligations of the Company upon Termination.

  

 5 









 (a)         Good Reason; Other Than for Cause,
Death or Disability. If, within 2 years following a Change in Control, the Company shall terminate the Executive’s employment other than for Cause, Disability or death, or the Executive shall terminate employment for Good Reason:

         (i)        the Company shall pay
to the Executive in a lump sum in cash within 60 days after the Date of Termination, subject to the Executive’s execution and nonrevocation, within 52 days after the Date of Termination, of the general release described in Section 11:

         A.        the product of 2 times
the sum of (x) the Executive’s annual bonus, including any deferred amounts (based upon the higher of (1) the Executive’s target bonus for the fiscal year in which the Change in Control occurs (or, if the Executive’s target
bonus for such period has not been established at the time of the Change in Control, the Executive’s target bonus for the fiscal year prior to the fiscal year in which the Change in Control occurs) and (2) the bonus the Executive received
for the fiscal year immediately preceding the fiscal year in which the Change in Control occurs) and (y) the Executive’s annual base salary (based upon the higher of (i) the Executive’s annual base salary as of the Date of
Termination or (ii) the highest annual base salary the Executive received within the 12-month period prior to the Change in Control); 
         B.        the sum of (x) the Executive’s annual base salary through the Date of Termination to the extent not
theretofore paid or deferred pursuant to an irrevocable election under any deferred compensation arrangement subject to Section 409A of the Code, and (y) the product of (1) the Executive’s annual bonus for the fiscal year in
which the Change in Control occured, assuming that the Executive achieved his target (or, if the Executive’s target bonus for such period has not been established at the time of the Change in Control, the Executive’s target bonus for the
fiscal year prior to the fiscal year in which the Change in Control occurs) and (2) a fraction, the numerator of which is the number of days in the fiscal year in which the Date of Termination occured through the Date of Termination and the
denominator of which is 365 (the sum of the amounts described in clauses (x) and (y) shall be hereinafter referred to as the “Accrued Obligations”); and 
         C.        if applicable, any compensation
previously deferred by Executive under the Unum Deferred Compensation Plan (together with any earnings and interest thereon), unless payment of such deferred compensation in a lump sum cash amount within 30 days after the Date of Termination would
(x) violate the terms of the applicable plan or (y) result in the imposition of taxation or penalties pursuant to Section 409A of the Code. 
                 (ii)    the Company
shall continue to provide, for a period of 2 years following the Executive’s Date of Termination, the Executive (and the Executive’s 

  

 6 









 
dependents, if applicable) with the same level of medical, dental, disability and life insurance benefits upon substantially the same terms and conditions
(including contributions required by the Executive for such benefits) as existed immediately prior to the Executive’s Date of Termination (or, if more favorable to the Executive, as such benefits and terms and conditions existed immediately
prior to the Change in Control); provided that, if the Executive cannot continue to participate in the Company plans providing such benefits, the Company shall otherwise provide such benefits on the same after-tax basis as if continued participation
had been permitted; provided, however, that the medical and dental benefits provided pursuant to this paragraph shall be provided in such a manner that such benefits (and the costs and premiums thereof) are excluded from the
Executive’s income for federal income tax purposes and, if the Company reasonably determines that providing continued coverage under one or more of its benefit plans could be taxable to the Executive, the Company may provide such benefits at
the level required hereby through the purchase of individual insurance coverage. Notwithstanding the foregoing, (x) if and to the extent required to avoid the imposition of taxes and penalties under Internal Revenue Code Section 409A, the
Executive will pay the entire cost of such coverage for the first 6 months after the Date of Termination and the Company will reimburse the Executive for the Company’s share of such costs, determined pursuant to this paragraph, on the six-month
anniversary of the Executive’s “separation from service” as defined under Internal Revenue Code Section 409A, and (y) in the event the Executive becomes reemployed with another employer and becomes eligible to receive
welfare benefits from such employer, the welfare benefits described herein shall be secondary to such benefits during the period of the Executive’s eligibility, but only to the extent that the Company reimburses the Executive for any increased
cost and provides any additional benefits necessary to give the Executive the benefits provided hereunder; provided, however, that such reimbursements shall be provided only in such a manner that such reimbursements are excluded from
the Executive’s income for federal income tax purposes. 
                 (iii)        notwithstanding any provision of any Company equity plan or any award agreement granted
thereunder, all stock options, restricted stock awards and other equity based awards granted to the Executive on or after the date hereof (the “Equity Awards”) shall vest and shall remain exercisable for a period of 90 days from the Date
of Termination or the earlier expiration of their initial full scheduled term; provided, that, any Equity Awards that constitute “nonqualified deferred compensation” for purposes of Section 409A of the Code will vest
immediately, but shall not be paid until the date on which such Equity Awards would otherwise be payable in accordance with the terms of the Company equity plan under which they were granted. 
                 (iv)        the Company shall pay to the Executive in a lump sum in cash within 60 days after the Date
of Termination, subject to the Executive’s execution and nonrevocation, within 52 days after the Date of Termination, of the general release described in Section 11, an amount equal to the excess of (A) the actuarial equivalent of the
Executive’s benefit under the Company’s tax-qualified defined benefit pension plan (the “Retirement Plan”) (utilizing actuarial assumptions no less favorable to the 

  

 7 









 
Executive than those in effect under such plan immediately prior to the Effective Date) and the supplemental defined benefit pension plan (the
“SERP”) that the Executive would receive if the Executive’s employment continued for 2 additional years after the Date of Termination, assuming for this purpose that (1) the Excecutive’s age is increased by the number of
years that the Executive is deemed to be so employed and (2) the Executive’s compensation in each of the 2 years is that referred to in Section 4(a)(i)(A) above, over (B) the actuarial equivalent of the Executive’s actual
benefit (paid or payable), if any, under the Retirement Plan and the SERP as of the Date of Termination. 
                 (v)        to the extent not theretofore paid or provided, the Company shall timely pay or provide to
the Executive any other amounts or benefits required to be paid or provided or which the Executive is eligible to receive under any plan, program, policy or practice or contract or agreement of the Company and its affiliated companies through the
Date of Termination (such other amounts and benefits shall be hereinafter referred to as the “Other Benefits”). 
                 (vi)      the Company shall provide individual outplacement services to the Executive in accordance with the
practices and policies of the Company in effect immediately prior to the Change in Control of the Company. 
 Notwithstanding anything in
this Agreement to the contrary, if (i) the Executive’s employment is terminated prior to a Change in Control for reasons that would have constituted a Good Reason or without Cause termination if they had occurred following a Change in
Control; (ii) the Executive reasonably demonstrates that such termination (or Good Reason event) was in anticipation of, in connection with, or was at the request of a third party who had indicated an intention or taken steps reasonably
calculated to effect a Change in Control; and (iii) a Change in Control involving such third party (or a party competing with such third party to effectuate a Change in Control) does occur, then for purposes of this Agreement, the Executive
shall be treated as if the Change in Control occurred on the date immediately prior to the date of such termination of employment or event constituting Good Reason. 
                 (b)        Death or Disability. If the Executive’s employment is terminated by reason of the
Executive’s death or disability, this Agreement shall terminate without further obligations to the Executive’s legal representatives or to the Executive, as the case may be, under this Agreement, other than for payment of Accrued
Obligations and the timely payment or provision of Other Benefits. Accrued Obligations shall be paid to the Executive, the Executive’s estate or beneficiary, as applicable, in a lump sum in cash within 30 days of the Date of Termination.

                 (c)        Cause; Other than for Good Reason. If the Executive’s employment shall be
terminated for Cause or the Executive terminates his employment without Good Reason, this Agreement shall terminate without further obligations to the Executive other than the obligation to pay to the Executive (i) his Annual Base Salary
through the Date of Termination to the extent theretofore unpaid and (ii) the Other Benefits. 
  

 8 









                 5.        Non-exclusivity of Rights. Except as specifically provided, nothing in this Agreement
shall prevent or limit the Executive’s continuing or future participation in any plan, program, policy or practice provided by the Company or any of its affiliated companies and for which the Executive may qualify, nor, subject to Sections 1
and 10(f), shall anything herein limit or otherwise affect such rights as the Executive may have under any contract or agreement with the Company or any of its affiliated companies. Amounts which are vested benefits or which the Executive is
otherwise entitled to receive under any plan, policy, practice or program of or any contract or agreement with the Company or any of its affiliated companies at or subsequent to the Date of Termination shall be payable in accordance with such plan,
policy, practice or program or contract or agreement except as explicitly modified by this Agreement; provided that the Executive shall not be eligible for severance benefits under any other program or policy of the Company. 
                 6.        Full Settlement. The Company’s obligation to make the payments provided for in
this Agreement and otherwise to perform its obligations hereunder shall not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action which the Company may have against the Executive or others. In no event shall
the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement, and such amounts shall not be reduced whether or not the
Executive obtains other employment. The Company agrees to pay as incurred (within 10 days following the Company’s receipt of an invoice from the Executive), at any time from the Change in Control through the Executive’s remaining lifetime
(or, if longer, through the 20th anniversary of the Change in Control), to the full extent permitted by law, all legal fees and expenses which the Executive may reasonably incur as a result of any contest (regardless of the outcome thereof) pursued
or defended against in good faith by the Executive regarding the validity or enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof (including as a result of any contest by the Executive about
the amount of any payment pursuant to this Agreement) from and after a Change in Control, plus in each case interest on any delayed payment at the applicable Federal rate provided for in Section 7872(f)(2)(A) of the Code. In order to comply
with Section 409A of the Code, in no event shall the payments by the Company under this Section 6 be made later than the end of the calendar year next following the calendar year in which such fees and expenses were incurred; provided,
that the Executive shall have submitted an invoice for such fees and expenses at least 10 days before the end of the calendar year next following the calendar year in which such fees and expenses were incurred. The amount of such legal fees and
expenses that the Company is obligated to pay in any given calendar year shall not affect the legal fees and expenses that the Company is obligated to pay in any other calendar year, and the Executive’s right to have the Company pay such legal
fees and expenses may not be liquidated or exchanged for any other benefit. 
                 7.        Certain Additional Payments by the Company. 
                           (a)        Anything in this Agreement to the
contrary notwithstanding and except as set forth below, in the event it shall be determined that any payment or distribution by the Company to or for the benefit of the Executive (whether paid or payable or distributed or 

  

 9 









 
distributable pursuant to the terms of this Agreement or otherwise, but determined without regard to any additional payments required under this
Section 7) (a “Payment”), would be subject to the excise tax imposed by Section 4999 of the Code or any interest or penalties are incurred by the Executive with respect to such excise tax (such excise tax, together with any such
interest and penalties, are hereinafter collectively referred to as the “Excise Tax”), then the Executive shall be entitled to receive an additional payment (a “Gross-Up Payment”) in an amount such that after payment by the
Executive of all taxes (including any interest or penalties imposed with respect to such taxes), including, without limitation, any income taxes (and any interest and penalties imposed with respect thereto) and Excise Tax imposed upon the Gross-Up
Payment, but excluding any income taxes and penalties imposed pursuant to Section 409A of the Code, the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments. Notwithstanding the foregoing
provisions of this Section 7(a), if it shall be determined that the Executive is entitled to a Gross-Up Payment, but that the Payments do not exceed 110% of the greatest amount that could be paid to the Executive such that the receipt of
Payments would not give rise to any Excise Tax (the “Reduced Amount”), then no Gross-Up Payment shall be made to the Executive and the amounts payable under this Agreement shall be reduced to the Reduced Amount. The reduction of payments
hereunder, if applicable, shall be made by reducing the payments and benefits under the following sections in the following order: (i) Section 4(a)(i)(A), (ii) Section 4(a)(iv), (iii) Section 4(a)(v),
(iv) Section 4(a)(vi), (v) Section 4(a)(i)(B), (vi) Equity Awards described in Section 4(a)(iii) subject to performance-based vesting conditions, and (vii) Equity Awards described in Section 4(a)(iii) not
subject to performance-based vesting conditions. If the reduction of the amounts payable under this Agreement would not result in a reduction of the Payments to the Reduced Amount, no amounts payable under this Agreement shall be reduced pursuant to
this Section 7(a). The Company’s obligation to make Gross-Up Payments under this Section 7 shall not be conditioned upon the Executive’s termination of employment. 
                 (b)        Subject to the provisions of Section 7(c), all determinations required to be made under
this Section 7, including whether and when a Gross-Up Payment is required and the amount of such Gross-Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by a nationally recognized certified public
accounting firm as may be designated by the Company prior to a Change in Control and reasonably acceptable to the Executive (the “Accounting Firm”) which shall provide detailed supporting calculations both to the Company and the Executive
within 15 business days of the receipt of notice from the Executive that there has been a Payment, or such earlier time as is requested by the Company. In the event that the Accounting Firm is serving as accountant or auditor for the individual,
entity or group affecting the Change in Control, the Company shall appoint another nationally recognized accounting firm to make the determinations required hereunder (which accounting firm shall then be referred to as the Accounting Firm
hereunder). All fees and expenses of the Accounting Firm shall be borne solely by the Company. Any determination by the Accounting Firm shall be binding upon the Company and the Executive. As a result of the uncertainty in the application of
Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments which will not have been made by the Company should have been made (“Underpayment”), consistent
with the calculations required to be made hereunder. In the event that the Company

exhausts its remedies pursuant to Section 7(c) and the Executive thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall
determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by the Company to or for the benefit of the Executive. 
                 (c)        The Executive shall notify the Company in writing of any claim by the Internal Revenue
Service that, if successful, would require the payment by the Company of the Gross-Up Payment. Such notification shall be given as soon as practicable but no later than 10 business days after the Executive is informed in writing of such claim and
shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. The Executive shall not pay such claim prior to the expiration of the 30-day period following the date on which it gives such notice to
the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies the Executive in writing prior to the expiration of such period that the Company desires to contest such
claim, the Executive shall: 
                 (i)        give the Company any information reasonably requested by the Company relating to such claim,

                 (ii)       take such action in connection with contesting such claim as the Company shall reasonably request in
writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company, 
                 (iii)     cooperate
with the Company in good faith in order effectively to contest such claim, and 
                 (iv)      permit the Company to participate in any proceedings relating to such claim; provided, however,
that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold the Executive harmless, on an after-tax basis, for any Excise Tax
or income tax (including interest and penalties with respect thereto) imposed as a result of such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this Section 7(c), the Company shall control
all proceedings taken in connection with such contest and, at its sole discretion, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the applicable taxing authority in respect of such claim and may,
at its sole discretion, either pay the tax claimed to the appropriate taxing authority on behalf of the Executive and direct the Executive to sue for a refund or contest the claim in any permissible manner, and the Executive agrees to prosecute such
contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that, if the Company directs the Executive to pay such claim
and sue for a refund, the Company shall indemnify and hold the Executive harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or penalties) imposed with respect to such payment 

  

 11 









 
or with respect to any imputed income with respect to such payment; and provided, further, that any extension of the statute of limitations
relating to payment of taxes for the taxable year of the Executive with respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore, the Company’s control of the contest shall be limited
to issues with respect to which a Gross-Up Payment would be payable hereunder and the Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority.

                 (d)        If, after the receipt by the Executive of an amount paid by the Company on the
Executive’s behalf pursuant to Section 7(c), the Executive becomes entitled to receive any refund with respect to such claim, the Executive shall (subject to the Company’s complying with the requirements of Section 7(c), if
applicable) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after payment by the Company of an amount on the Executive’s behalf pursuant to
Section 7(c), a determination is made that the Executive shall not be entitled to any refund with respect to such claim and the Company does not notify the Executive in writing of its intent to contest such denial of refund prior to the
expiration of 30 days after such determination, then such payment shall not be required to be repaid and the amount of such payment shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid. 
                 (e)        Any Gross-Up Payment, as determined pursuant to this Section 7, shall be paid by the
Company to the Executive within 5 days of the receipt of the Accounting Firm’s determination; provided that, the Gross-Up Payment shall in all events be paid no later than the end of the Executive’s taxable year next following the
Executive’s taxable year in which the Excise Tax (and any income or other related taxes or interest or penalties thereon) on a Payment is remitted to the Internal Revenue Service or any other applicable taxing authority or, in the case of
amounts relating to a claim described in Section 7(c) that does not result in the remittance of any federal, state, local and foreign income, excise, social security and other taxes, the calendar year in which the claim is finally settled or
otherwise resolved. Notwithstanding any other provision of this Section 7, the Company may, in its sole discretion, withhold and pay over to the Internal Revenue Service or any other applicable taxing authority, for the benefit of the
Executive, all or any portion of any Gross-Up Payment, and the Executive hereby consents to such withholding. 
         8.        Confidential Information and Non-Solicitation. 
                   (a)        The Executive hereby acknowledges that, as an employee of the Company, he will be
making use of, acquiring and adding to confidential information of a special and unique nature and value relating to the Company and its strategic plan and financial operations. The Executive further recognizes and acknowledges that all confidential
information is the exclusive property of the Company, is material and confidential, and is critical to the successful conduct of the business of the Company. Accordingly, the Executive hereby covenants and agrees that he will use confidential
information for the benefit of the Company only and shall not at any time, directly or indirectly, during the term of this Agreement, and 

  

 12 









 
thereafter for all periods during which severance or other amount is paid, divulge, reveal or communicate any confidential information to any person, firm,
corporation or entity whatsoever, or use any confidential information for his own benefit or for the benefit of others. The Executive also agrees not to hire or solicit for hire, directly or indirectly, any employee on the payroll of the Company for
any third party during the term of this Agreement and for one year after the Date of Termination without the prior written consent of the Company. In no event shall an asserted violation of the provisions of this Section 8 constitute a basis
for deferring or withholding any amounts otherwise payable to the Executive under this Agreement. 
                 (b)        Any termination of the Executive’s employment or of this Agreement shall have no effect
on the continuing operation of this Section 8. 
                 (c)        The Executive acknowledges and agrees that the Company will have no adequate remedy at law,
and could be irreparably harmed, if the Executive breaches or threatens to breach any of the provisions of this Section 8. The Executive agrees that the Company shall be entitled to equitable and/or injunctive relief to prevent any breach or
threatened breach of this Section 8, and to specific performance of each of the terms hereof in addition to any other legal or equitable remedies that the Company may have. The Executive further agrees that he shall not, in any equity
proceeding relating to the enforcement of the terms of this Section 8, raise the defense that the Company has an adequate remedy at law. 
         9.      Successors. 
                 (a)        This Agreement is personal to the Executive and without the prior
written consent of the Company shall not be assignable by the Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive’s legal representatives.

                 (b)        This Agreement shall inure to the benefit of and be binding upon the Company and its
successors and assigns. 
                 (c)        The Company will require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it
if no such succession had taken place. As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by
operation of law, or otherwise.

         10.      Miscellaneous.

shall be governed by and construed in accordance with the laws of the State of Delaware, without reference to principles of conflict of laws. The captions of this Agreement are not part of the provisions hereof and shall have no force or effect.

                              (c)        The invalidity

 UNUM GROUP 
 AGREEMENT AND GENERAL RELEASE 
 EXHIBIT A 
 THIS AGREEMENT AND GENERAL RELEASE (this “Agreement”) is made by and between [insert executive name] (“you”) and Unum
Group (“Unum”), its predecessors, successors and assigns. When used herein, Unum shall also include its affiliates, and its current or former officers, directors, shareholders, agents, attorneys, representatives, employees, benefit plans
and plan fiduciaries and trustees. You agree that you have executed this Agreement on your own behalf, and on behalf of any heirs, agents, representatives, successors and assigns that you may have now or in the future. 
 1.  NON-ADMISSIONS 
         Unum denies that it has violated any law, constitution, regulation, statute, ordinance, or any other legal duty existing at common law or otherwise as regards its relationship with you. It is
understood and contemplated that this Agreement is for the compromise of potential and disputed claims, and that the consideration provided in this Agreement is not and shall not be construed as an admission of liability on the part of any party or
parties hereby released. 
 2.  CONSIDERATION 
         In consideration of this Agreement, Unum will provide you with the severance benefits described in the
Change in Control Severance Agreement beteween you and Unum (the “CIC Agreement”). You acknowledge that Unum will withhold from amounts due to you appropriate payroll taxes and will offset against the remainder any advances, loans, debts,
sales deficits or similar amounts you owe Unum or for which Unum may be held responsible. For any amounts not subject to withholding, you agree that Unum has made no representation to you concerning tax consequences of the payments, and you agree
that you have not relied on any such representation. You agree to indemnify and hold harmless Unum from any taxes, assessments, interest, or penalties that Unum may at any time incur by reason of demand, suit, or proceeding brought against it for
any taxes, interest, penalties or assessments arising out of this Agreement. 
 3.  GENERAL RELEASE 
         For and in consideration of the payment, mutual promises, covenants, and agreements made herein by and
between you and Unum, you unconditionally and generally release Unum from each and every action, claim, right, liability or demand of any kind and nature, and from any claims which may be derived therefrom, that you had, have, or might hereafter
claim to have against Unum or any current or former employee, agent, successor or predecessor of Unum at common law, public policy or otherwise, particularly including, but not by way of limitation, the following: all claims for personal injury,
including claims for emotional distress; any claim arising under the Age Discrimination in Employment Act of 1967, as amended; Title VII of the Civil Rights Act of 1991; the Americans with Disabilities Act of 1990; the Rehabilitation Act of 1973;
the Fair Labor Standards Act; the National Labor Relations Act; Sections 1981 through 1988 of Title 42 of the 

  

 16 









 
United States Code; the Immigration Reform and Control Act; the False Claims Act; the Occupational Safety and Health Act; the Worker Adjustment and
Retraining Notification Act; the Employment Retirement Income Security Act of 1974 (save for a benefit claim as provided below); any other federal, state or local law dealing with discrimination in employment on the basis of sex, race, color,
national origin, religion, disability, age, sexual orientation or any other grounds; any claim for wrongful discharge or breach of contract; and any other claims based on tort, whether based on common law, public policy or otherwise. It is your
intent to release all claims of every nature and kind whether known or unknown, accrued or unaccrued, which you may have against Unum as of the date of the execution of this Agreement. 
         It is expressly understood and agreed by you that this Agreement does not include your vested rights, if
any, in the Unum Pension or in the Unum 401(k) Retirement Plan, any other rights you may have to benefits under Unum’s welfare benefit plans, or any vested rights you may have under a stock option or long term incentive plan, or any rights to
deferred compensation. Such retirement plan, welfare plan, stock options or deferred compensation rights survive unaffected by this release, subject to the laws and plan documents governing those plans. This Agreement does not include any rights or
claims against Unum or those associated with Unum that you may have which arise after the date you sign the Agreement, or any claim that you may have to unemployment compensation or workers’ compensation benefits. 
 4.        FUTURE LEGAL ACTION 
         You agree that you will never institute a claim or charge of employment discrimination with any agency
(except as provided below) or sue Unum, concerning any claim you may have relating to your employment with Unum or the termination of that employment. You also agree to waive all right to any damages or other relief. 
         If you violate this Agreement by suing Unum, you agree that you will pay all costs and expenses incurred
by Unum in defending against the suit, including reasonable attorneys’ fees. 
         If you
violate this Agreement by filing a lawsuit or charge against Unum, you agree to pay back the entire payment that you received under the Plan within 7 days after you file your lawsuit or charge. Such payment should be sent to the Executive
Vice-President and General Counsel, Unum Group, 1 Fountain Square, Chattanooga, TN 37402. If you fail to timely pay back the entire payment, you hereby agree to dismiss, with prejudice, any such lawsuit or charge. 
         This promise does not prevent you from filing an employment discrimination charge with the EEOC or a state
or local fair employment agency or from cooperating with the EEOC or such an agency in an investigation. However, if you file such a charge, you agree that you have waived all rights to any money, damages, attorneys’ fees, costs, right to sue
or other relief or remedy in any such charge. 
 5.      CONFIDENTIALITY AND NON-DISCLOSURE OF
INFORMATION 
          You hereby acknowledge that, as an employee of Unum, you have
made use of, acquired and added to confidential information of a special and unique nature and value relating to Unum and its strategic plan and financial operations. You further recognize and acknowledge that all confidential information is the
exclusive property of Unum, is material and confidential, and is critical to the successful conduct of the business of Unum. Accordingly, you hereby covenant and 

  

 17 









 
agree that you will use confidential information for the benefit of Unum only and shall not at any time, directly or indirectly, during the term of the CIC
Agreement and thereafter for all periods during which severance or other such amounts are paid, divulge, reveal or communicate any confidential information to any person, firm, corporation or entity whatsoever, or use any confidential information
for his own benefit or for the benefit of others. You agree that you have returned all company property including, but not limited to, books, records, files, computers, and phones. 
 6.        NON-SOLICITATION OF OTHER UNUM EMPLOYEES AND BROKERS 
                 If you are an officer or in a sales position, you further
agree that for a period of one year after your employment termination from Unum, you will not directly or indirectly solicit, assist or induce any of Unum’s sales representatives, officers or brokers to terminate their relationships with Unum.
You also agree that for a period of one year after your employment termination from Unum, you will not directly or indirectly solicit, assist or induce any of Unum’s sales representatives or officers to become employed by or associated with
another insurance company. You acknowledge and agree that Unum has a valid need to protect its business by prohibiting such solicitation and that these restrictions are both reasonable and necessary to protect Unum’s business. It is not the
intent of Unum to prohibit you from obtaining employment in an industry either related or unrelated to Unum’s business. 
 7.        NON-DISPARAGEMENT 
                 You further agree not to make any statement, oral or written, publicly or in private, which is reasonably foreseeable as harming Unum’s
business interests, discloses confidential or proprietary information gained during your employment, or impacts negatively on Unum’s business reputation or its reputation in the community. Nothing in this paragraph will be construed to prevent
you from communicating with or responding to a request for information from a federal, state, administrative agency or court. 
 8.            CONSULTATION 
                 By executing this Agreement, you acknowledge that you have been advised to consult with an attorney in the matter as Unum has recommended, that
you have had ample opportunity to discuss fully with your attorney the terms and the legal significance of this Agreement, and that you freely enter into this Agreement. 
 9.        ENTIRE AGREEMENT/ MODIFICATIONS 
                 This Agreement contains the entire understanding between the parties and may not be modified except in writing signed by all authorized parties
to this Agreement. You acknowledge that this Agreement is executed without any reliance on any statement or representation by Unum or any agents of Unum concerning the nature and extent of the damages or legal liability thereof. 
 10.        TERMINATION OF EMPLOYMENT 
  

 18 









                 You agree
that your employment with Unum will end on [insert date], irrevocably and forever. Unless otherwise modified by the parties in accordance with paragraph 9 above, you will not seek re-employment, nor be re-employed. If such a
modification occurs and you are re-employed, you may be required to repay Unum part or all of the consideration referred to in Paragraph 2. Specifically, Unum shall recapture severance benefits paid under the Plan, in the event that you are
subsequently rehired by Unum or any of its subsidiaries or affiliates, by requiring repayment in an amount equal to the severance benefit payable in respect of that number of weeks equal to the excess of (i) the number of weeks for which
severance benefits were provided to you over (ii) the number of weeks between the date on which your employment with Unum first terminated and the date on which you recommenced employment with Unum. 
 11.        FORTY-FIVE DAY PERIOD 
                 You understand that you have a period of 45 days
beginning [insert date of executive’s receipt of Agreement] and ending [insert date 45 days from date of receipt] to consider this Agreement before signing it. You further understand that you may use as much of this
(45) day period as you wish should you decide to enter into this Agreement. You may not execute this Agreement prior to your last day of employment.

 13.        TRIAL DEFENSE / INVESTIGATIONS 
                 It is understood by both parties that if after your termination you are named as a defendant in a lawsuit concerning any task you performed
within the scope of your employment at Unum, Unum acknowledges its common law duty to defend. You agree that if you have knowledge of any unlawful conduct on the part of Unum, you must immediately disclose it to Unum and agree to fully cooperate in
any trial and/or investigation of such matter. You also agree to fully cooperate in any investigation Unum undertakes into matters occurring during your employment with Unum. 
 14.        SEVERABILITY 
                 If any clause or provision of this Agreement is found invalid, illegal or otherwise unenforceable, such finding shall not affect the validity,
legality and enforceability of any other clause or provision or constitute a cause of action in favor of either party against the other.
