EXHIBIT 10.5

RESTRICTED STOCK 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.

(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”), [            ] Shares (the “Restricted Stock”) 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 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”):

(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 Shares of Restricted Stock 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 shall lapse, and such Restricted Stock 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 Director’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. Nontransferability of the Restricted Stock.

During the Restriction Period, the Shares covered by the Restricted Stock 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.

3. Rights as a Stockholder.

Except as otherwise specifically provided in this Agreement, during the Restriction Period the Director shall have all the rights of a stockholder with respect to the Restricted Stock, including without limitation the right to vote the Restricted Stock and the right to receive any dividends with respect thereto. If the Company declares and pays dividends on the Common Stock during the Restriction Period, the Director shall be paid dividends with respect to the Restricted Stock at such time as dividends are paid to stockholders of Common Stock generally.

4. Certificates.

Certificates representing the Restricted Stock as originally or from time to time constituted shall bear the following legend:

The Shares represented by this stock certificate have been granted as restricted stock under a Restricted Stock Agreement between the registered holder of these Shares and the Company. The Shares represented by this stock certificate may not be sold, exchanged, assigned, transferred, pledged, hypothecated or otherwise encumbered or disposed of until the restrictions set forth in the Restricted Stock Agreement between the registered holder of these Shares and the Company shall have lapsed.

As soon as administratively practicable after the end of the Restriction Period, the Company shall deliver to the Director or his or her personal representative, in book-position or certificate form, the formerly Restricted Stock that does not bear any restrictive legend making reference to this Agreement. Such Shares shall be free of restrictions, except for any restrictions required under Federal securities laws.

5. Adjustment; Change in Control.

In the event of certain transactions during the Restricted Period, the Restricted Stock 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 vests, the restrictions applicable to the Restricted Stock shall lapse, and such Restricted Stock shall become free of all restrictions and become fully vested and transferable in full, consistent with Section 10(a)(ii) 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 a Director in connection with the Restricted Stock, together with any and all other fees and expenses necessarily incurred by the Company in connection therewith.

7. Other Restrictions.

(a) The Restricted Stock 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 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 subject to 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, 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.
