Right expires or is cancelled unexercised as to any shares of Common Stock
covered thereby, or (ii) any Award in respect of shares is forfeited for any
reason under the Plan, such shares shall thereafter be again available for award
pursuant to the Plan.

SECTION 6.  Stock Options.

(a)    Grant. Subject to the provisions of the Plan, the Committee shall
       have sole and complete authority to determine the Employees to whom
       Options shall be granted, the number of shares to be covered by each
       Option, the Option Price, as defined below, therefor and the conditions
       and limitations applicable to the exercise of the Option. The Committee
       shall have the authority to grant Incentive Stock Options, or to grant
       Non-Qualified Stock Options, or to grant both types of Options. In the
       case of Incentive Stock Options, the terms and conditions of such grants
       shall be subject to and comply with such rules as may be prescribed by
       Section 422A of the Code and any regulations implementing Section 422A.

(b)    Option Price. The Committee shall establish the exercise price of the
       Option (the "Option Price") at the time each Option is granted, which
       Option Price shall not be less than 100% of the Fair Market Value of the
       Common Stock on the date of grant.

(c)    Exercise.

       (1)   Each Option shall be exercisable at such times and subject to such
             terms and conditions as the Committee may, in its sole discretion,
             specify in the applicable Award or thereafter; provided, however,
             that in no event may any Option granted hereunder be exercisable
             after the expiration of ten years from the date of grant. The
             Committee may impose such conditions with respect to the exercise
             of Options, including without limitation, any relating to the
             application of federal or state securities laws, as it may deem
             necessary or advisable.

       (2)   No shares shall be delivered pursuant to any exercise of an Option
             until payment in full of the Option Price therefor is received by
             the Corporation. Such payment may be made in cash, or its
             equivalent, or, subject to such rules and guidelines as the
             Committee may establish, by exchanging shares of Common Stock owned
             by the optionee (which are not the subject of any pledge or other
             security interest), or by a combination of the foregoing, provided
             that the combined value of all cash and cash equivalents and the
             Fair Market Value of any such Common Stock so tendered to the
             Corporation, valued as of the date of such tender, is at least
             equal to such Option Price.



(d) Termination of Employment.

       (1)   Except as provided below, if a Participant ceases to be an Employee
             other than by reason of death, retirement or disability, any then
             outstanding Options may be exercised any time before their
             expiration date or within three months after the date of
             termination, whichever is earlier, but only to the extent that such
             Options were exercisable when employment ceased, absent a
             determination by the Committee to the contrary; provided, however,
             that a Participant is terminated for cause the Committee may
             determine that no Option may be exercised at any time after the
             termination date.

       (2)   If a Participant's employment terminates because of death or
             disability, all then outstanding Options previously granted to the
             Participant will become exercisable. In the case of death of the
             Participant, such Options may be exercised at any time before their
             expiration date or within three years after the date of
             termination, whichever is earlier. In the case of permanent
             disability, such Options may be exercised at any time before their
             expiration date.

       (3)   If a Participant's employment terminates because of retirement
             prior to January 1, 1995, any then outstanding Options may be
             exercised any time before their expiration date or within three
             years after the date of termination, whichever is earlier, but only
             to the extent that such Options were exercisable when employment
             ceased absent a determination by the Committee to the contrary. If
             a Participant's employment terminates because of retirement on or
             after January 1, 1995, any then outstanding Options may be
             exercised any time before their expiration date or within five
             years after the date of termination, whichever is earlier, but only
             to the extent that such Options were exercisable when employment
             ceased absent a determination by the Committee to the contrary.

SECTION 7.  Stock Appreciation Rights.

(a)    The Committee shall have the authority to grant Stock Appreciation Rights
       in tandem with the grant of an Option or freestanding and unrelated to an
       Option. Stock Appreciation Rights granted in tandem with an Option may be
       granted either at or after the time of the grant of such Option.

       Stock Appreciation Rights or any applicable portion thereof granted in
       tandem with a given Option shall only be exercisable to the extent that
       the related Option is exercisable and shall terminate and no longer be
       exercisable upon the expiration or cancellation of the related Option.

       The exercise of an Option shall result in an immediate forfeiture of any
       Stock Appreciation Right granted in tandem with that Option, and the
       exercise of such Stock Appreciation Right shall cause an immediate
       forfeiture of its related Option. Stock Appreciation Rights shall not be
       exercisable after the expiration of ten years from date of grant. A Stock
       Appreciation Right granted in tandem with an Option may be exercised by
       an optionee, in accordance with this Section 7, by surrendering the
       applicable portion of the related Option. Upon such exercise and
       surrender, the optionee shall be entitled to receive an amount determined
       in the manner prescribed in this Section 7.



(b)    A Stock Appreciation Right shall entitle the Participant to receive
       from the Corporation an amount equal to the excess of the Fair Market
       Value of a share of Common Stock on the date of the exercise of the Stock
       Appreciation Right over the grant price thereof, provided that the
       Committee may for administrative convenience determine that, for any
       Stock Appreciation Right which is not related to an Incentive Stock
       Option and can only be exercised during limited periods of time in order
       to satisfy the conditions of certain rules of the Securities and Exchange
       Commission, the exercise of any such Stock Appreciation Right for cash
       during such limited period shall be deemed to occur for all purposes
       hereunder on the day during such limited period on which the Fair Market
       Value of the Stock is the highest. Any such determination by the
       Committee may be changed by the Committee from time to time and may
       govern the exercise of Stock Appreciation Rights granted prior to such
       determination as well as Stock Appreciation Rights thereafter granted.
       The Committee shall determine whether Stock Appreciation Rights shall be
       settled in cash, shares of Common Stock or a combination of cash and
       shares of Common Stock.

SECTION 8.  Limited Rights.

(a)    The Committee shall have the authority to grant Limited Rights in tandem
       with the grant of an Option or freestanding and unrelated to an Option.
       Limited Rights granted in tandem with an Option may be granted either at
       or after the time of the grant of such Option.

       Limited Rights or any applicable portion thereof granted in tandem with a
       given Option shall terminate and no longer be exercisable upon the
       expiration or cancellation of the related Option. The exercise of an
       Option shall result in an immediate forfeiture of any Limited Right
       granted in tandem with that Option, and the exercise of such Limited
       Right shall cause an immediate forfeiture of its related Option.

       A Limited Right granted in tandem with an Option may be exercised by an
       optionee, in accordance with this Section 8, by surrendering the
       applicable portion of the related Option. Upon such exercise and
       surrender, the optionee shall be entitled to receive an amount determined
       in the manner prescribed in this Section 8.

(b)    Limited Rights shall only be exercisable during the 30 day period
       following a Change in Control as defined in Section 11 and shall not be
       exercisable after the expiration of ten years from the date of grant.

(c)    Upon the exercise of a Limited Right, an optionee shall be entitled
       to receive from the Corporation an amount in cash equal in value to the
       excess of (i) the higher of (A) the highest price per share paid in
       connection with the Change in Control or (B) the highest Fair Market
       Value per share as reported in the Wall Street Journal at any time during
       the 60 day period preceding the Change in Control over (ii) in the case
       of a Limited Right granted in tandem with an Option, the Option Price per
       share specified in the related Option and in the case of all other
       Limited Rights, the price per share established in the grant of the
       Limited Right, such excess to be multiplied by the number of shares in
       respect of which the Limited Right shall have been exercised; provided,
       however, that upon the exercise of a Limited Right granted in tandem with
       an Incentive Stock Option, the amount set forth in clause (i) shall not
       exceed the Fair Market Value of a share on the date of exercise of the
       Limited Right.

(d)    Limited Rights shall be subject to such other terms and conditions, not
       inconsistent with the provisions of the Plan, as shall be determined from
       time to time by the Committee. This Section 8 shall be interpreted in
       accordance and consistent with the principles set forth in Rule 16b-3 of
       the Exchange Act.



SECTION 9.  Restricted Stock.

(a)    Subject to the provisions of the Plan, the Committee shall have sole
       and complete authority to determine the Employees to whom shares of
       Restricted Stock shall be granted, the number of shares of Restricted
       Stock to be granted to each Participant, the duration of the Restricted
       Period during which, and the conditions under which, the Restricted Stock
       may be forfeited to the Corporation, and the other terms and conditions
       of such Awards. The Committee may determine that the Restricted Period
       applicable to a particular grant may vary depending upon the attainment
       of particular conditions, such as corporate earnings, share price or
       other targets set by the Committee.

(b)    Shares of Restricted Stock may not be sold, assigned, transferred,
       pledged or otherwise encumbered, except as herein provided, during the
       Restricted Period. Certificates issued in respect of shares of Restricted
       Stock shall be registered in the name of the Participant and deposited by
       such Participant, together with a stock power endorsed in blank, with the
       Corporation. At the expiration of the Restricted Period, the Corporation
       shall deliver such certificates to the Participant or the Participant's
       legal representative.

(c)    If a Participant's employment terminates by reasons of disability or
       death, any Restricted Stock held by such Participant shall thereafter
       vest and any restriction lapse, to the extent such Restricted Stock would
       have become vested and no longer subject to such restrictions within one
       year from the time of termination had the Participant continued to
       fulfill all of the conditions of the Restricted Stock during such period
       (or on such accelerated basis as the Committee may determine at or after
       grant). Unless otherwise determined by the Committee, if a Participant's
       employment terminates for any reasons other than permanent disability or
       death, any Restricted Stock which is unvested or subject to restriction
       shall thereupon be forfeited.

SECTION 10.  Restricted Stock Units.

(a)    The Committee may, in its discretion, grant Restricted Stock Units to
       such eligible Participants as it may select. Restricted Stock Units shall
       entitle the Participant to receive one share of Common Stock per Unit at
       the times and subject to the conditions determined by the Committee. The
       Committee shall determine the number of Units to be granted to each
       Participant, whether or not the Restricted Stock Units are designed to
       satisfy the requirements of Section 162(m) of the Code and the
       regulations thereunder, the duration of the Restricted Period (if any)
       during which, and the conditions under which, the Restricted Stock Units
       may be forfeited to the Corporation, the schedule for settlement, and any
       other terms and conditions relating to each grant, not inconsistent with
       the terms of this Plan, as the Committee shall deem advisable. The
       Committee may provide that the holder of a Restricted Stock Unit Award
       shall receive cash or Common Stock equal in value to the dividends paid
       with respect to a specified number of shares of the Common Stock, as such
       dividends accrue or upon settlement of the Restricted Stock Unit Award,
       in which case dividends may be deemed to have been reinvested in
       additional Common Stock or such other investment vehicles as the
       Committee may specify.

(b)    Restricted Stock Units may not be sold, assigned, transferred, pledged or
       otherwise encumbered.

(c)    Subject to the renumbered Section 12 of this Plan, all of the provisions
       governing the satisfaction of Performance Measures and the termination of
       the Restriction Period relating to a Restricted Stock Unit Award, or any
       cancellation or forfeiture of shares of Restricted Stock Units upon
       termination of employment of the Participant, whether by reason of death,
       permanent disability, retirement, or otherwise, shall be set forth in the
       Agreement relating to such Restricted Stock Unit Award, or in guidelines
       established by the Committee and made applicable to such Restricted Stock
       Unit Award.



SECTION 11.  Non-Employee Director Options.

Notwithstanding any of the other provisions of the Plan to the contrary, the
provisions of this Section 10 shall only apply to a non-employee member of the
Board. The other provisions of the Plan shall apply to grants of Options under
this Section 10 to the extent not inconsistent with the provisions of this
Section.

(a)    This Section 11 shall be administered by the Board.

(b)    Each non-employee member of the Board shall receive Non-Qualified Stock
       Options in accordance with the provisions of this Section 11.

(c)    (i)   Recipients of Options under this Section 11 shall enter into a
             stock option agreement with the Corporation, which agreement shall
             set forth, among other things, the exercise price of the Option,
             the term of the Option and provisions regarding exercisability of
             the Option granted thereunder.

       (ii)  On the Effective Date (as defined below) each non-employee member
             of the Board of the Corporation shall receive Options to purchase
             2,000 shares of Common Stock. Beginning in 1997, on the date after
             each annual stockholders meeting of the Corporation each continuing
             non-employee member of the Board shall be granted an Option to
             purchase 4,000 shares of Common Stock and, beginning in 1990, each
             newly elected non-employee director shall be granted an Option to
             purchase 6,000 shares of Common Stock. The Option Price per share
             of Common Stock purchasable under such Options shall be equal to
             the Fair Market Value of the Common Stock on the date of grant.
             Such Option shall remain exercisable until the earlier of ten years
             from the date of grant or the termination of any post-directorship
             consultancy agreement with the Corporation; provided, however, that
             if such consultancy agreement terminates by reason of death or
             disability any then outstanding Options may be exercised (x) at any
             time before their expiration date or (y), if such termination is by
             reason of death, within three years of the date of death, whichever
             is earlier. Such Options shall be exercisable one year from the
             date of grant by payment in full in cash or in shares of Common
             Stock having a Fair Market Value equal to the Option Price or in a
             combination of cash and such shares.

(d)    The Board may not amend, alter, or discontinue this Section 11 without
       the approval of the stockholders of the Corporation.

SECTION 12.  Change of Control.

Notwithstanding anything to the contrary contained herein, unless otherwise set
forth in any agreement relating to an Award, each outstanding Option, Stock
Appreciation Right and Limited Right granted under the Plan shall become
exercisable in full for the aggregate number of shares covered thereby, and any
restriction or deferral limitation applicable to any Restricted Stock or
Restricted Stock Units shall lapse and such shares and Awards shall be deemed
fully vested, in the event of a Change in Control (as hereinafter defined).



For purposes of this Plan, a Change in Control shall be deemed to have occurred
upon the first to occur of the following events:

       (i)   any "person," as such term is used in Sections 13(d) and 14(d) of
             the Exchange Act (other than the Corporation or any corporation
             owned, directly or indirectly, by the stockholders of the
             Corporation in substantially the same proportions as their
             ownership of stock of the Corporation), is or becomes the
             "beneficial owner" (as defined in Rule 13d-3 under the Exchange
             Act), directly or indirectly, of securities of the Corporation
             representing more than 40% of the number of the Corporation's then
             outstanding securities;

       (ii)  during any period of two consecutive years, individuals who at the
             beginning of such period constitute the Board, and any new director
             (other than a director designated by a person who has entered into
             an agreement with the Corporation to effect a transaction described
             in Subsection 12(i), (iii) or (iv) of this Section 12) whose
             election by the Board or nomination for election by the
             Corporation's stockholders was approved by a vote of at least
             two-thirds (2/3) of the directors then still in office who either
             were directors at the beginning of the period or whose election or
             nomination for election was previously so approved, cease for any
             reason to constitute at least a majority thereof;

       (iii) the stockholders of the Corporation approve a merger or
             consolidation of the Corporation with any other corporation, other
             than a merger or consolidation which would result in the voting
             securities of the Corporation outstanding immediately prior thereto
             continuing to represent (either by remaining outstanding or being
             converted into voting securities of the surviving entity) more than
             60% of the number of outstanding securities of the Corporation or
             such surviving entity outstanding immediately after such merger or
             consolidation; or

       (iv)  the stockholders of the Corporation approve a plan of complete
             liquidation of the Corporation or an agreement for the sale or
             disposition by the Corporation of all or substantially all of the
             Corporation's assets.

SECTION 13.  General Provisions.

(a)    Withholding. The Employer shall have the right to deduct from all amounts
       paid to a Participant in cash (whether under this Plan or otherwise) any
       taxes required by law to be withheld in respect of Awards under this
       Plan. In the case of payments of Awards in the form of Common Stock, at
       the Committee's discretion the Participant may be required to pay to the
       Employer the amount of any taxes required to be withheld with respect to
       such Common Stock, or, in lieu thereof, to the extent permitted by
       applicable federal and state securities laws, the Employer shall have the
       right to retain (or the Participant may be offered the opportunity to
       elect to tender) the number of shares of Common Stock whose Fair Market
       Value equals the amount required to be withheld. The Optionee shall be
       entitled to elect to pay all or a portion of the exercise price for
       options granted under this Plan and any withholding taxes in connection
       with such exercise by having the shares of Common Stock to be issued by
       UNUM Corporation pursuant to such exercise sold by a broker-dealer under
       circumstances meeting the requirements of 12 C.F.R. Section 220.

(b)    Nontransferability. No Award shall be assignable or transferable, and no
       right or interest of any Participant shall be subject to any lien,
       obligation or liability of the Participant, except by will or the laws of
       descent and distribution.



(c)    No Right to Employment. No person shall have any claim or right to be
       granted an Award, and the grant of an Award shall not be construed as
       giving a Participant the right to be retained in the employ of the
       Employer. Further, the Employer expressly reserves the right at any time
       to dismiss a Participant free from any liability, or any claim under the
       Plan, except as provided herein or in any agreement entered into with
       respect to an Award.

(d)    No Rights as Stockholder. Subject to the provisions of the applicable
       Award, no Participant or transferee of an Option or Restricted Stock
       Units shall have any rights as a stockholder with respect to any shares
       of Common Stock to be distributed under the Plan until he or she has
       become the holder thereof. Notwithstanding the foregoing, in connection
       with each grant of Restricted Stock hereunder, the applicable Award shall
       specify if and to what extent the Participant shall not be entitled to
       the rights of a stockholder in respect of such Restricted Stock.

(e)    Construction of the Plan. The validity, construction, interpretation,
       administration and effect of the Plan and of its rules and regulations,
       and rights relating to the Plan, shall be determined solely in accordance
       with the laws of the State of Delaware.

(f)    Effective Date. Subject to the approval of the stockholders of the
       Corporation, the Plan shall be effective on February 9, 1990 (the
       "Effective Date"). No Options or Awards may be granted under the Plan
       after February 9, 2000.

(g)    Amendment of Plan. The Board may amend, suspend or terminate the Plan or
       any portion thereof at any time, provided that no amendment shall be made
       without stockholder approval if such approval is necessary to comply with
       any tax or regulatory requirement, including for these purposes any
       approval requirement which is a prerequisite for exemptive relief under
       Section 16(b) of the Exchange Act. Notwithstanding anything to the
       contrary contained herein, the Committee may amend the Plan in such
       manner as may be necessary so as to have the Plan conform with local
       rules and regulations. The Chief Executive Officer shall be authorized to
       make minor or administrative modifications to the Plan as well as
       modification to the Plan which may be dictated by requirements of federal
       or state statutes applicable to the Corporation or authorized or made
       desirable by such statutes. No modification or termination of the Plan
       shall, without the optionee's consent, alter or impair any of his or her
       rights or obligations under any Option, Stock Appreciation Right or
       Limited Right theretofore granted to him or her under the Plan.

(h)    Amendment of Award. The Committee may amend, modify or terminate any
       outstanding Award with the Participant's consent at any time prior to
       payment or exercise in any manner not inconsistent with the terms of the
       Plan, including without limitation, (i) to change the date or dates as of
       which (A) an Option, Stock Appreciation Right or Limited Right becomes
       exercisable; (B) Restricted Stock or Restricted Stock Units becomes
       nonforfeitable; or (ii) to cancel and reissue an Award under such
       different terms and conditions as it determines appropriate.

(i)    Hardship Distributions. In no event shall any Option granted under this
       Plan be exercisable through payment of the Option Price in cash during
       the period of one year following a hardship distribution under the UNUM
       Employees Retirement Savings Plan and Trust, as defined therein.



(j)    Adjustments and Assumption. In the event of a reorganization,
       recapitalization, stock split, stock dividend, combination of shares,
       merger, consolidation, distribution of assets, or any other change in the
       corporate structure or shares of the Corporation, the Committee shall
       make such adjustments as it deems appropriate in the number and kind of
       shares authorized by the Plan, in the number and kind of shares covered
       by the Awards granted, and in the purchase price of outstanding Options.
       In the event of any merger, consolidation or other reorganization in
       which the Corporation is not the surviving or continuing corporation, all
       Awards granted hereunder and outstanding on the date of such event shall
       be assumed by the surviving or continuing corporation with appropriate
       adjustment as to the number and kind of shares and purchase price of the
       shares.

(k)    In addition to the purposes set forth in Section 1, the Committee may
       grant Awards to eligible Participants in order to compensate such
       Participants to surrender existing rights to receive benefits from the
       Employer under this or any other benefit plan or arrangement.
