Notice of time based restricted stock unit and restricted stock unit agreement under the Aflac Incorporated Long-Term Incentive Plan, as amended and restated February 14, 2017

Award. The Company hereby grants to the Participant an Award of

Forfeiture. Except as otherwise provided in Paragraph C, below, upon termination of the Participant’s employment with the Company and all of its Affiliates, any Stock Units which shall not already have vested pursuant to Paragraph C, below, or as otherwise provided in the Plan, shall be immediately forfeited by the Participant. 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.

Vesting. The Stock Units shall vest on one or more calendar dates as set forth in the Notice of Grant; provided that upon the death or disability of the Participant while employed by the Company or an Affiliate, all outstanding Stock Units shall become immediately fully vested. For the purposes of this Paragraph C, “Disability” means a physical or mental condition that qualifies the Grantee for long-term disability benefits under a long-term disability plan maintained by the Company or an Affiliate employing the Grantee.

Delivery of Shares. Within 74 days of the calendar vesting date set forth in the Notice of Grant, the Company shall deliver a number of shares equal to the number of vested shares. In the event that any Stock Units vest prior to the applicable calendar vesting date set forth in the Notice of Grant due to the Participant’s disability or voluntary retirement after attaining age 60, the shares subject to such Stock Units shall not be delivered to the Participant until the applicable calendar vesting date. Notwithstanding the foregoing provisions of this Paragraph D, if any Restricted Stock Units become vested upon a Participant’s death, or if the Participant dies after becoming vested in Stock Units due to retirement or disability, shares

Dividends. Dividends are paid in the form of shares rather than cash, The number of Stock Units shall be increased by the number of shares that would have been received as a dividend had the Stock Units been outstanding shares. Additional Stock Units credited under the Section shall vest or be forfeited, and shares shall be delivered to Participants, at the same time as the Stock Units to which they relate.

Miscellaneous.

No Rights as a Stockholder. Prior to delivery of shares pursuant to Paragraph E, the Participant shall have no rights of a stockholder of the Company, including the right to vote such shares or to receive any cash dividends.

No Additional Rights. Neither this Agreement nor any of the transactions contemplated hereby shall affect any right of the Participant to continue as an employee of the Company or any Affiliate or otherwise to provide services to the Company or any Affiliate or any of the terms or conditions of any such service.

Restriction on Transfer. Except as otherwise provided in the Plan, the Participant may not transfer or assign any of the Participant’s rights with respect to this Award, whether voluntary or involuntary, by operation of law or otherwise. Unless the Committee determines otherwise, if a Participant makes any attempt to transfer or assign the rights with respect to this Award, the Award shall be immediately forfeited by the Participant without consideration at any time.

Securities Laws Requirements.
