EXHIBIT 10.6

RESTRICTED STOCK UNIT AGREEMENT WITH DIRECTOR

THIS AGREEMENT, dated as of the [ ] day of [            ], 2007, between Unum
Group, a Delaware corporation (the “Company”), and [            ] (the
“Director”).

W I T N E S S E T H

In consideration of the mutual promises and covenants made herein and the mutual
benefits to be derived herefrom, the parties hereto agree as follows:

1. Grant, Vesting and Forfeiture of Restricted Stock Units.

(a) Grant. Subject to the provisions of this Agreement and to the provisions of
the Unum Group Stock Incentive Plan of 2007 (the “Plan”), the Company hereby
grants to the Director, as of [            ] (the “Grant Date”), [            ]
Restricted Stock Units (the “Restricted Stock Units”), each with respect to one
share of common stock of the Company, par value $0.10 per Share (“Common
Stock”). All capitalized terms used herein, to the extent not defined, shall
have the meaning set forth in the Plan.

(b) Vesting during the Restriction Period. Subject to the terms and conditions
of this Agreement, the Restricted Stock Units shall vest and no longer be
subject to any restriction on the anniversaries of the Grant Date set forth
below (such period during which restrictions apply is the “Restriction Period”):

 

Vesting Dates

(Anniversaries of Grant Date)

     Percentage of Total Grant Vesting

 

(c) Forfeiture upon Termination of Service; Accelerated Vesting upon Termination
Due to Death or Disability. Upon the Director’s Termination of Service (as
defined below) for any reason (other than due to the Director’s death,
Disability or Retirement) during the Restriction Period, all Restricted Stock
Units still subject to restriction shall be forfeited. Upon the Director’s
Termination of Service during the Restriction Period due to the Director’s
death, Disability or Retirement, the restrictions applicable to the Restricted
Stock Units shall lapse, and such Restricted Stock Units shall become free of
all restrictions and become fully vested. For purposes of this Agreement,
“Retirement” shall mean the Director’s Termination of Service after the
attainment of at least four years of service, in each case, only if such
Termination of Service is approved as a “Retirement” by the Committee. For
purposes of this Agreement, service with the Company shall include service with
the Company’s Affiliates and its successors. Nothing in this Agreement or the
Plan shall confer upon the Director any right to continue in the service of the
Company or any of its Affiliates or interfere in any way with the right of the
Company or any such Affiliates to terminate the

--------------------------------------------------------------------------------

Direc tor’s service at any time. For purposes of this Agreement, “Termination of
Service” means the termination of the Director’s service with the Company and
any of its Subsidiaries or Affiliates. Unless otherwise determined by the
Committee, if the Director’s service with the Company and its Affiliates
terminates but such Director continues to provide services to the Company and
its Affiliates in another capacity, such change in status shall not be deemed a
Termination of Service. Temporary absences from service because of illness,
vacation or leave of absence and transfers among the Company and its
Subsidiaries and Affiliates shall not be considered Terminations of Service.

2. Settlement of Units.

Subject to Section 8 (pertaining to the withholding of taxes), as soon as
practicable after the Restriction Period expires, the Company shall deliver to
the Director or his or her personal representative, in book-position or
certificate form, one Share that does not bear any restrictive legend making
reference to this Agreement for each Share subject to the Restricted Stock Unit.
Notwithstanding the foregoing, the Company shall be entitled to hold the Shares
issuable upon settlement of Restricted Stock Units that have vested until the
Company shall have received from the Director a duly executed Form W-9 or W-8,
as applicable.

3. Nontransferability of the Restricted Stock Units.

During the Restriction Period and until such time as the Restricted Stock Units
are ultimately settled as provided in Section 2 above, the Restricted Stock
Units and the Shares covered by the Restricted Stock Units shall not be
transferable by the Director by means of sale, assignment, exchange,
encumbrance, pledge, hedge or otherwise. Any purported or attempted transfer of
such Shares or such rights shall be null and void.

4. Rights as a Stockholder.

During the Restriction Period, the Director shall not be entitled to any rights
of a stockholder with respect to the Restricted Stock Units (including, without
limitation, any voting rights), provided that with respect to any dividends paid
on Shares underlying the Restricted Stock Units, such dividends will be
reinvested into additional Restricted Stock Units, which shall vest at such time
as the underlying Restricted Stock Units vest and be settled at that time.

5. Adjustment; Change in Control.

In the event of certain transactions during the Restricted Period, the
Restricted Stock Units shall be subject to adjustment as provided in
Section 3(d) of the Plan or any applicable successor provision under the Plan.
In the event of a Change in Control before the Restricted Stock Units vest, the
restrictions applicable to the Restricted Stock Units shall lapse, such
Restricted Stock Units shall become free of all restrictions and become fully
vested, consistent with Section 10(a)(iii) of the Plan.

6. Payment of Transfer Taxes, Fees and Other Expenses.

The Company agrees to pay any and all original issue taxes and stock transfer
taxes that may be imposed on the issuance of shares received by an Director in
connection with the Re

--------------------------------------------------------------------------------

stricted Stock Units, together with any and all other fees and expenses
necessarily incurred by the Company in connection therewith.

7. Other Restrictions.

(a) The Restricted Stock Units shall be subject to the requirement that, if at
any time the Committee shall determine that (i) the listing, registration or
qualification of the Shares subject or related thereto upon any securities
exchange or under any state or federal law is required, or (ii) the consent or
approval of any government regulatory body is required, then in any such event,
the grant of Restricted Stock Units shall not be effective unless such listing,
registration, qualification, consent or approval shall have been effected or
obtained free of any conditions not acceptable to the Committee.

(b) The Director is a Restricted Person under the Company’s Insider Trading
Policy (as in effect from time to time and any successor policies). Accordingly,
the Director shall be required to obtain pre-clearance from the General Counsel
or Securities Counsel of the Company prior to purchasing or selling any of the
Company’s securities, including any shares issued upon vesting of the Restricted
Stock Units, and may be prohibited from selling such shares other than during an
open trading window. The Director further acknowledges that, in its discretion,
the Company may prohibit the Director from selling such shares even during an
open trading window if the Company has concerns over the potential for insider
trading.

8. Taxes.

As a non-employee director of the Company, the Director will be responsible for,
and will duly and timely comply with all applicable laws relating to, the
collection, payment, reporting and remittance of any and all federal, state or
local taxes, charges or fees resulting from the receipt of amounts described in
this Agreement. Neither the Company nor any of its Affiliates shall be liable
for any such taxes, charges or fees resulting from the receipt of amounts
described in this Agreement.

14. Amendment.

The Company may modify, amend or waive the terms of the Restricted Stock Unit
award, prospectively or retroactively, but no such modification, amendment or
waiver shall materially impair the rights of the Director without his or her
consent, except as required by applicable law, stock exchange rules, tax rules
or accounting rules. The waiver by either party of compliance with any provision
of this Agreement shall not operate or be construed as a waiver of any other
provision of this Agreement, or of any subsequent breach by such party of a
provision of this Agreement.

compensation” within the meaning of Section 409A of the Code, and it is the

the Grant Date that an amendment to this Agreement is necessary to ensure the
foregoing, it may, notwithstanding Section 14, make such amendment, effective as
of the Grant Date or any later date, without the consent of the Director.
