A.Award. The Company hereby grants to the Participant a Restricted Stock Award of #QuantityGranted# shares (each, a “share”) of Aflac Incorporated Common Stock, par value $.10 per share, subject to the terms and conditions set forth herein and in the Plan. The Award is subject to adjustment from time to time as provided in Section 3(c) of the Plan.

B.Restrictions on Transfer. Until the restrictions on transfer of the shares lapse as provided in Paragraph D below, or as otherwise provided in the Plan, no transfer of the shares or any of the Participant’s rights with respect to such shares, whether voluntary or involuntary, by operation of law or otherwise, shall be permitted.

C.Forfeiture. Except as otherwise provided in Paragraph D below, upon termination of the Participant’s employment with the Company and all of its Affiliates, any shares as to which the restrictions on transferability shall not already have lapsed pursuant to Paragraph D below, or as otherwise provided in the Plan, shall be immediately forfeited by the Participant and transferred to, and reacquired by, the Company without consideration of any kind. In the case of a Participant who served as a non-employee sales associate of an Affiliate of the Company immediately before becoming an employee, if such Participant voluntarily terminates employment with the Company or an Affiliate but continues immediately thereafter to perform bona fide services for an Affiliate as a sales associate, the Participant shall be treated as continuing employment with the Company or an Affiliate for purposes of this Agreement. If the Committee or its delegate determines, in its sole discretion, that such a Participant is no longer providing bona fide services to an Affiliate as a sales associate, the Participant shall be deemed to have terminated employment for purposes of this Agreement on the date as of which such services are determined to have ceased. The Committee may require the Participant to provide such evidence of continuing services as it deems appropriate. The Committee may establish policies and procedures to be followed by the Committee or its delegate in determining whether a Participant is providing bona fide services as a sales associate, and such policies (including any amendments or modifications thereto) shall be considered part of this Agreement and shall be binding on the Participant.

D.Vesting. The shares shall vest as set forth in the Notice of Grant; provided that (i) the shares shall vest immediately upon the death or disability (within the meaning of Code Section 422(c)(6)) of the Participant while employed by the Company or any Affiliate, and (ii) in the event of the Participant’s Retirement then (A) any service-based vesting requirement shall be deemed fully satisfied if such Restricted Stock Award was made at least one full year prior to such termination of employment, and (B) to the extent performance vesting goals are established in respect of the shares, any shares as to which the restrictions on transferability shall not already have lapsed shall vest at the end of the performance period to the extent the performance vesting goals are satisfied; provided, to the extent (1) such performance vesting goals are not satisfied at the end of the performance period, or (2) the Committee determines before the end of the performance period such performance vesting goals will not be attained, such shares will be forfeited. For the purposes of this Paragraph D, “Retirement” means voluntary termination of employment with the Company and all Affiliates after attaining age 60. Upon vesting, as described above in this Paragraph D, and within thirty (30) days thereafter, the shares shall be released (paid) to the Participant free of the restrictions described in this Agreement.
