 Exhibit 10.5 
 UNUM GROUP 
 (f/k/a UNUMPROVIDENT CORPORATION) 
 AMENDED AND RESTATED STOCK PLAN OF 1999 
 ARTICLE I 
 Purpose 
 1.1    General.  The purpose of the Unum Group Amended and Restated Stock Plan of 1999 (the “Plan”) is to promote the success, and enhance the value, of Unum Group (the “Corporation”), by
linking the personal interests of its employees, officers, producers and directors to those of Corporation stockholders and by providing such persons with an incentive for outstanding performance. The Plan is further intended to provide flexibility
to the Corporation in its ability to motivate, attract, and retain the services of employees, officers, producers and directors upon whose judgment, interest, and special effort the successful conduct of the Corporation’s operation is largely
dependent. Accordingly, the Plan permits the grant of incentive awards from time to time to selected employees, officers, producers and directors.

 Effective Date 
 2.1    Effective Date.  The Plan was effective as of January 1, 1999 (the “Effective Date”), was amended and restated by the Board on February 18, 2005 effective as of
the approval of the stockholders on may 12, 2005, and further amended by the Committee on August 15, 2007. 
 2.2    Termination of Plan.  No Awards may be granted under the Plan after the ten-year anniversary of the Effective Date, but the Plan shall remain in effect as long as any Awards under it are outstanding.

to meet the objectives of the Plan. 
 Notwithstanding the above, the Board or the Committee may expressly delegate to a
special committee consisting of one or more directors who are also officers of the Corporation some or all of the Committee’s authority under subsections (a) through (g) above with respect to those eligible Participants who, at the
time of the grant are not, and are not anticipated to become, either (I) Covered Employees or (ii) persons subject to the insider trading rules of Section 16 of the 1934 Act. Further, the Committee may delegate its general

number of shares of Stock with respect to one or more Options and/or SARs that may be granted during any one calendar year under the Plan to any one 

  

 6 









 
Participant shall be 1,000,000. The maximum Fair Market Value (measured as of the date of grant) of any Awards other than Options and SARs that may be

 ARTICLE 6 
 Eligibility 
 6.1.    General.  Awards may be granted only to individuals who are employees, officers, Producers or directors of the Corporation or a Parent or Subsidiary.

 ARTICLE 7 
 Stock Options

 7.1.    General.  The Committee is authorized to grant Options to Participants on the
following terms and conditions: 
 (a) Exercise Price.  The exercise price per share of Stock under
an Option shall be determined by the Committee, provided that the exercise price for any Option shall not be less than the Fair Market Value as of the date of the grant. 
 (b) Time and Conditions of Exercise.  The Committee shall determine the time or times at which an Option may be
exercised in whole or in part, subject to Section 7.1(f). The Committee also shall determine the performance or other conditions, if any, that must be satisfied before all or part of an Option may be exercised or vested. Except with respect to
Options subject to Code Section 409A, the Committee may waive any exercise provisions at any time in whole or in part based upon factors as the Committee may determine in its sole discretion so that the Option becomes exercisable or vested at
an earlier date. Notwithstanding the foregoing, except as may be set forth in an Award Agreement with respect to death, Disability or Retirement of a Participant, Options will not be exercisable before the expiration of three years from the date of
grant (but vesting may be ratable over such period). 
 (c) Payment.  The Committee shall determine
the methods by which the exercise price of an Option may be paid, the form of payment, including, without limitation, cash, shares of Stock, or other property (including “cashless exercise” arrangements), and the methods by which shares of
Stock shall be delivered or deemed to be delivered to Participants; provided, however, that if shares of Stock are used to pay the exercise price of an Option, such shares must have been held by the Participant for at least six months. When shares
of Stock are delivered, such delivery may be by attestation of ownership or actual delivery of one or more certificates. Failure by the Committee to specify methods by which the exercise price of an Option may be paid or the form of payment shall be
deemed to express the Committee’s determination that all methods and forms of payment under the Plan are permitted for that Option. 
 (d) Evidence of Grant.  All Options shall be evidenced by a written Award Agreement between the Corporation and the Participant. The Award Agreement shall include such provisions, not inconsistent with the
Plan, as may be specified by the Committee. 
 (e) Exercise Term.  In no event may an Option be
exercisable for more than ten years from the date of its grant.

Incentive Stock Options granted under the Plan must comply with the following additional rules:

 (b) Exercise.  In no event may any Incentive Stock Option be exercisable for more than ten years from the date
of its grant. 
 (c) Lapse of Option.  An Incentive Stock Option shall lapse under the earliest of
the following circumstances; provided, however, that the Committee may, prior to the lapse of the Incentive Stock Option under the circumstances described in paragraphs (3), (4) and (5) below, provide in writing that the Option will extend
until a later date, but if Option is exercised after the dates specified in paragraphs (3), (4) and (5) below, it will automatically become a Non-Qualified Stock Option: 
 (1) The Incentive Stock Option shall lapse as of the option expiration date set forth in the Award Agreement. 

(2) The Incentive Stock Option shall lapse ten years after it is granted, unless an earlier time is set in the Award
Agreement. 
 (3) If the Participant terminates employment for any reason other than as provided in paragraph
(4) or (5) below, the Incentive Stock Option shall lapse, unless it is previously exercised, three months after the Participant’s termination of employment; provided, however, that if the Participant’s employment is terminated by
the Corporation for cause (as determined by the Corporation ), the Incentive Stock Option shall (to the extent not previously exercised) lapse immediately. 
 (4) If the Participant terminates employment by reason of his Disability, the Incentive Stock Option shall lapse, unless it is previously exercised, one year after the Participant’s
termination of employment. 
 (5) If the Participant dies while employed, or during the three—month
period described in paragraph (3) or during the one - year period described in paragraph (4) and before the Option otherwise lapses, the Option shall lapse one year after the Participant’s death. Upon the Participant’s death, any
exercisable Incentive Stock Options may be exercised by the Participant’s beneficiary, determined in accordance with Section 11.6. 
 Unless the exercisability of the Incentive Stock Option is accelerated as provided in Article 11, if a Participant exercises an Option after termination of employment, the Option may be exercised only with respect to
the shares that were otherwise vested on the Participant’s termination of employment. 
 (d) Individual
Dollar Limitation.  The aggregate Fair Market Value (determined as of the time an Award is made) of all shares of Stock with respect to which Incentive Stock Options are first exercisable by a Participant in any calendar year may not
exceed $100,000.00. 
 (e) Ten Percent Owners.  No Incentive Stock Option shall be granted to any
individual who, at the date of grant, owns stock possessing more than ten percent of the total combined voting power of all classes of stock of the Corporation or any Parent or Subsidiary unless the exercise price per share 

  

 8 









 
of such Option is at least 110% of the Fair Market Value per share of Stock at the date of grant and the Option expires no later than five years after the
date of grant. 
 (f) Expiration of Incentive Stock Options.  No Award of an Incentive Stock Option
may be made pursuant to the Plan after the day immediately prior to the tenth anniversary of the Effective Date. 
 (g) Right to Exercise.  During a Participant’s lifetime, an Incentive Stock Option may be exercised only by the Participant or, in the case of the Participant’s Disability, by the Participant’s guardian or legal
representative. 
 (h) Directors.  The Committee may not grant an Incentive Stock Option to a
non—employee director. The Committee may grant an Incentive Stock Option to a director who is also an employee of the Corporation or Parent or Subsidiary but only in that individual’s position as an employee and not as a director.

certain limited situations (including the death, Disability or Retirement of the Participant or a Change in Control), Restricted Stock Awards subject solely to continued employment restrictions shall have a restriction period of not less than three
years from the date of grant (but may have pro-rata vesting over such time) and shall be paid within 2 1/2 months of the close of
the year in which the restrictions lapse. Except as otherwise determined by the Committee at the time of the grant of the Award or thereafter, upon termination of employment during the applicable restriction period or upon failure to satisfy a
performance goal during the applicable restriction period, Restricted Stock that is at that time subject to restrictions shall be forfeited and reacquired by the Corporation; provided however that the Committee may provide in any Award Agreement
that restrictions or forfeiture conditions relating to Restricted Stock will be waived in whole or in part in the event of terminations resulting from specified causes, and the Committee may in other cases waive in whole or in part restrictions or
forfeiture conditions relating to the Restricted Stock, with the exception of the minimum three year vesting period described above. 
 9.4.    Certificates For Restricted Stock.  Restricted Stock granted under the Plan may be evidenced in such manner as the Committee shall determine. If certificates representing shares

Committee is authorized to grant Dividend Equivalents to Participants subject to such terms and conditions as may be selected by the Committee. Dividend Equivalents shall entitle the Participant to receive payments equal to dividends with respect to
all or a portion of the number of shares of Stock subject to an Award, as determined by the Committee. The Committee may provide that Dividend Equivalents be paid or distributed when accrued or be deemed to have been reinvested in additional shares
of Stock, or otherwise reinvested. If paid or distributed, Dividend Equivalents shall be paid or distributed within 2 1/2 months
of the close of the year in which vested. 
 ARTICLE 11 
 Provisions Applicable To Awards 
 11.1.    Stand-alone, Tandem, and
Substitute Awards.   Awards granted under the Plan may, in the discretion of the Committee, be granted either alone or in addition to, in tandem with, or in substitution for, any other Award granted under the Plan. If an Award is granted
in substitution for another Award, the Committee may require the surrender of such other Award in consideration of the grant of the new Award. Awards granted in addition to or in tandem with other Awards may be granted either at the same time as or
at a different time from the grant of such other Awards. 
 11.2.    Term of Award.   The term
of each Award shall be for the period as determined by the Committee, provided that in no event shall the term of any Incentive Stock Option or a Stock Appreciation Right granted in tandem with the Incentive Stock Option exceed a period of ten years

 10 









 11.3.    Form of Payment for Awards.   Subject to the terms
of the Plan and any applicable law or Award Agreement, payments or transfers to be made by the Corporation or a Parent or Subsidiary on the grant or exercise of an Award may be made in a single payment or transfer or in installments, and may be made
in such form as the Committee determines at or after the time of grant, including without limitation, cash, Stock, or other property, or any combination, in each case determined in accordance with rules adopted by, and at the discretion of, the
Committee, which shall be in compliance with Code Section 409A to the extent applicable. Further, to the extent required to comply with Section 409A of the Code, as determined by the Corporation’s outside counsel, one or more payments
under this Section 11 shall be delayed to the six month anniversary of the Participant’s separation from service, within the meaning of Code Section 409A. In addition, payments under this Section 11 may be delayed if timely
payment is administratively impracticable and the impracticability was unforeseeable, if making a timely payment would jeopardize the ability of Employer to continue as a going concern, or if deduction of the payment is restricted by Code
Section 162(m) and a reasonable person would not have anticipated that restriction at the time the legally binding right to the payment arose. In each case, payment must be made as soon as the reason for the delay ceases to exist. 

11.4.    Limits on Transfer.   No right or interest of a Participant in any unexercised or restricted
Award may be pledged, encumbered, or hypothecated to or in favor of any party other than the Corporation or a Parent or Subsidiary, or shall be subject to any lien, obligation, or liability of such Participant to any other party other than the
Corporation or a Parent or Subsidiary. No unexercised or restricted Award shall be assignable or transferable by a Participant other than by will or the laws of descent and distribution or, except in the case of an Incentive Stock Option, pursuant
to a domestic relations order that would satisfy Section 414(p)(1)(A) of the Code if such Section applied to an Award under the Plan; provided, however, that the Committee may (but need not) permit other transfers where the Committee concludes
that such transferability (i) does not result in accelerated taxation, (ii) does not cause any Option intended to be an Incentive Stock Option to fail to be described in Code Section 422(b), and (iii) is otherwise appropriate and
desirable, taking into account any factors deemed relevant, including without limitation, state or federal tax or securities laws applicable to transferable Awards. 
 11.5    Beneficiaries.   Notwithstanding Section 11.4, a Participant may, in the manner determined by the Committee, designate a beneficiary to exercise the
rights of the Participant and to receive any distribution with respect to any Award upon the Participant’s death. A beneficiary, legal guardian, legal representative, or other person claiming any rights under the Plan is subject to all terms
and conditions of the Plan and any Award Agreement applicable to the Participant, except to the extent the Plan and Award Agreement otherwise provide, and to any additional restrictions deemed necessary or appropriate by the Committee. If no
beneficiary has been designated or survives the Participant, payment shall be made to the Participant’s estate. Subject to the foregoing, a beneficiary designation may be changed or revoked by a Participant at any time provided the change or
revocation is filed with the Committee. 
 11.6.    Stock Certificates.   All Stock issuable
under the Plan is subject to any stop-transfer orders and other restrictions as the Committee deems necessary or advisable to comply with federal or state securities laws, rules and regulations and the rules of any national securities exchange or
automated quotation system on which the Stock is listed, quoted, or traded. The Committee may place legends on any Stock certificate or issue instructions to the transfer agent to reference restrictions applicable to the Stock. 
 11.7    Acceleration Upon Death, Disability or Retirement.   Notwithstanding any other provision in the
Plan or any Participant’s Award Agreement to the contrary, upon the Participant’s death or Disability during his employment or service as a producer or director or upon the Participant’s Retirement, all outstanding Options, Stock
Appreciation Rights, and other Awards in the nature of rights that may be exercised shall become fully exercisable and all restrictions on outstanding Awards shall lapse. Any 

  

 11 









 
Option or Stock Appreciation Rights Awards shall thereafter continue or lapse in accordance with the other provisions of the Plan and the Award Agreement. To
the extent that this provision causes Incentive Stock Options to exceed the dollar limitation set forth in Section 7.2(d), the excess Options shall be deemed to be Non-Qualified Stock Options. 
 11.8.    Acceleration Upon a Change in Control.   Except as otherwise provided in the Award Agreement, upon
the occurrence of a Change in Control, all outstanding Options, Stock Appreciation Rights, and other Awards in the nature of rights that may be exercised shall become fully exercisable and all restrictions on outstanding Awards shall lapse. To the
extent that this provision causes Incentive Stock Options to exceed the dollar limitation set forth in Section 7.2(d), the excess Options shall be deemed to be Non-Qualified Stock Options. 
 11.9    Effect of Acceleration.   If an Award is accelerated under Section 11.8, the Committee may, in
its sole discretion, provide (i) that the Award will expire after a designated period of time after such acceleration to the extent not then exercised, (ii) that the Award will be settled in cash rather than Stock, (iii) that the
Award will be assumed by another party to the transaction giving rise to the acceleration or otherwise be equitably converted in connection with such transaction, or (iv) any combination of the foregoing. The Committee’s determination need
not be uniform and may be different for different Participants whether or not such Participants are similarly situated. 
 11.10.    Performance Goals.  The Committee may determine that any Award granted pursuant to this Plan to a Participant shall be determined on the basis of one or more of the following measures of corporate
performance, alone or in combination, which may be expressed in terms of Corporation-wide objectives or in terms of objectives that relate to the performance of a division, business unit, region, department or function within the Corporation or a
subsidiary: (a) return on equity, (b) overall or selected premium or sales growth, (c) stock performance, (d) expense efficiency ratios (ratio of expenses to premium income), (e) earnings per share, (f) market share,
(g) revenue, (h) customer service measures or indices, (i) underwriting efficiency and/or quality, (j) persistency factors, (k) total shareholder return, (l) earnings before interest and taxes (EBIT), (m) earnings
before interest, taxes, depreciation and amortization (EBITDA), (n) net income, (o) return on assets, (p) return on net assets, (q) economic value added, (r) shareholder value added, (s) embedded value added,
(t) net operating profit, (u) net operating profit after tax, (v) combined ratio, (w) expense ratio, (x) loss ratio, (y) premiums, (z) return on capital, (aa) return on invested capital, (bb) profit margin, or (cc)
risk based capital. The Committee has the right for any reason to reduce or increase the Award, notwithstanding the achievement of a specified goal. 
 11.11.    Termination of Employment.   The employment relationship shall be treated as continuing while the Participant is on military leave, sick leave, or other bona fide leave of
absence if the period of such leave does not exceed 6 months, or if longer, so long as the individual retains a right to reemployment with the service recipient under an applicable statute or by contract. A termination of employment shall not occur
in a circumstance in which a Participant transfers from the Corporation to one of its Parents or Subsidiaries, transfers from a Parent or Subsidiary to the Corporation, or transfers from one Parent or Subsidiary to another Parent or Subsidiary or in
the discretion of the Committee as specified at or prior to such occurrence, in the case of a spin-off, sale or disposition of the Participant’s employer from the Corporation or any Parent or Subsidiary. To the extent that this provision causes
the Incentive Stock Options to extend beyond three months from the date a Participant is deemed to be an employee of the Corporation, a Parent or Subsidiary for purposes of Section 424(f) of the Code, the Options held by such Participant shall
be deemed to be Non-Qualified Stock Options.

 ARTICLE 12 
 Changes In Capital Structure 
 12.1.   General.   In the event of a
corporate transaction involving the Corporation (including without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation split-up, spin-off, combination or exchange of
shares) the authorization limits under Section 5.1 and 5.4 shall be adjusted proportionately, and the Committee may adjust Awards to preserve the benefits or potential benefits of the Awards. Action by the Committee may include:
(I) adjustment of the number and kind of shares which may be delivered under the Plan; (ii) adjustment of the number and kind of shares subject to outstanding Awards, adjustment of the exercise price of outstanding Awards; and
(iv) any other adjustments that the Committee determines to be equitable. Without limiting the foregoing, in the event a stock dividend or stock split is declared upon the Stock, the authorization limits under Section 5.1 and 5.4 shall be
increased proportionately, and the shares of Stock then subject to each Award shall be increased proportionately without any change in the aggregate purchase price therefor. 
 ARTICLE 13 
 Amendment, Modification And Termination 
 13.1.   Amendment, Modification and Termination.   The Board or the Committee may, at any time and from time to time,
amend, modify or terminate the Plan without stockholder approval; provided, however, that the Board or Committee may condition any amendment or modification on the approval of stockholders of the Corporation if such approval is necessary or deemed
advisable with respect to tax, securities or other applicable laws, policies or regulations. 
 13.2   Awards
Previously Granted.   At any time and from time to time, the Committee may amend, modify or terminate any outstanding Award without approval of the Participant; provided, however, that subject to the terms of the applicable Award Agreement
such amendment, modification or termination shall not, without the Participant’s consent, reduce or diminish the value of such Award determined as if the Award had been exercised, vested, cashed in or otherwise settled on the date of such
amendment or termination; and provided further that, the original term of any Option may not be extended and, except as otherwise provided in the anti-dilution provision of the Plan, the exercise price of any Option may not be reduced. No
termination, amendment, or modification of the Plan shall adversely affect any Award previously granted under the Plan, without the written consent of the Participant. 
 ARTICLE 14 
 General Provisions 
 14.1.    No Rights to Awards.   No Participant or employee, officer, producer or director shall have any claim to be granted any Award under the Plan, and neither
the Corporation nor the Committee is obligated to treat Participants or eligible participants uniformly. 
 14.2.    No Stockholder Rights.   No Award gives the Participant any of the rights of a stockholder of the Corporation unless and until shares of Stock are in fact issued to such person in connection with such
Award. 
 14.3.    Withholding.   The Corporation or any Parent or Subsidiary shall have the
authority and the right to deduct or withhold, or require a Participant to remit to the Corporation, an amount sufficient to satisfy federal, state, and local taxes (including the Participant’s FICA obligation) required by law to be 

  

 13 









 
withheld with respect to any taxable event arising as a result of the Plan. With respect to withholding required upon any taxable event under the Plan, the
Committee may, at the time the Award is granted or thereafter, require or permit that any such withholding requirement be satisfied, in whole or in part, by withholding from the Award shares of Stock having a Fair Market Value on the date of
withholding equal to the minimum amount (and not any greater amount) required to be withheld for tax purposes, all in accordance with such procedures as the Committee establishes. 
 14.4.    No Right to Continued Service.   Nothing in the Plan or any Award Agreement shall interfere with
or limit in any way the right of the Corporation or any Parent or Subsidiary to terminate any Participant’s employment or status as an officer, Producer or director at any time, nor confer upon any Participant any right to continue as an
employee, officer, Producer or director of the Corporation or any Parent or Subsidiary. 
 14.5.    Unfunded Status of Awards.   The Plan is intended to be an “unfunded” plan for incentive and deferred compensation. With respect to any payments not yet made to a Participant pursuant to an
Award, nothing contained in the Plan or any Award Agreement shall give the Participant any rights that are greater than those of a general creditor of the Corporation or any Parent or Subsidiary. 
 14.6.    Relationship to Other Benefits.  No payment under the Plan shall be taken into account in
determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or benefit plan of the Corporation or any Parent or Subsidiary unless provided otherwise in such other plan. 
 14.7.    Expenses.   The expenses of administering the Plan shall be borne by the Corporation and its
Parents or Subsidiaries. 
 14.8.    Titles and Headings.   The titles and headings of the
Sections in the Plan are for convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control. 
 14.9.    Gender and Number. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine; the plural shall include the
singular and the singular shall include the plural. 
 14.10.    Fractional Shares.   No
fractional shares of Stock shall be issued and the Committee shall determine, in its discretion, whether cash shall be given in lieu of fractional shares or whether such fractional shares shall be eliminated by rounding up. 
 14.11.    Government and other Regulations.  The obligation of the Corporation to make payment of awards in
Stock or otherwise shall be subject to all applicable laws, rules, and regulations, and to such approvals by government agencies as may be required. The Corporation shall be under no obligation to register under the 1933 Act, or any state securities
act, any of the shares of Stock issued in connection with the Plan. The shares issued in connection with the Plan may in certain circumstances be exempt from registration under the 1933 Act, and the Corporation may restrict the transfer of such
shares in such manner as it deems advisable to ensure the availability of any such exemption. 
 14.12.
    Governing Law.   To the extent not governed by federal law, the Plan and all Award Agreements shall be construed in accordance with and governed by the laws of the State of Tennessee. 
  

 14 









 14.13.     Additional Provisions.   Each Award Agreement
may contain such other terms and conditions as the Committee may determine; provided that such other terms and conditions are not inconsistent with the provisions of this Plan. 
 The foregoing is hereby acknowledged as being the Unum Group Amended and Restated Stock Plan of 1999 as approved by the Stockholders of the Company on May 12, 2005, and as further amended by
the Committee as of August 15, 2007.
