Amended form of HNI Corporation 2017 Stock-Based Compensation Plan Restricted Stock Unit Award Agreement

Number of Restricted Stock Units Granted: __________

Grant Date: __________

Vesting of Restricted Stock Units: Subject to the terms of Section 7 and 8 below, 1/3 of the total number of Restricted Stock Units granted above, rounded up or down to the nearest whole share, will vest on each of the first, second, and third anniversaries of the Grant Date (each such date, a “Vesting Date”), provided that you remain continuously employed by the Corporation through such Vesting Date.

Impact of Vesting of Restricted Stock Units: On each Vesting Date, you will be issued a number of Shares equal to the number of Restricted Stock Units that become vested on that Vesting Date. A portion of these Shares will be withheld to pay applicable withholding taxes due on such Vesting Date. To the extent that payroll taxes are required to be withheld prior to a Vesting Date, the Corporation may withhold such taxes from your cash compensation payable by the Corporation in accordance with Section 3121(v) of the Code.

Stockholder Rights: Prior to the time that your Restricted Stock Units vest and the Corporation has issued Shares relating to such Restricted Stock Units, you will not be deemed to be the holder of, or to have any of the rights of a holder with respect to, any Shares deliverable with respect to such Restricted Stock Units. However, as of each date on which a cash dividend is paid to holders of Shares, a Divided Equivalent in an amount equal to the cash dividend that is paid on each Share, multiplied by the number of Restricted Stock Units that remain unvested and outstanding or otherwise have not been settled as of the dividend payment date (the “Dividend Equivalent Amount”) shall be credited to an unfunded account for your benefit. The aggregate Dividend Equivalent Amount, if any, credited to such account shall vest and be paid in cash at the same time and subject to the same vesting conditions as the corresponding Restricted Stock Units to which the Dividend Equivalent Amount relates. From and after the date Shares are actually issued or delivered upon settlement of the Restricted Stock Units, you then will have dividend rights with respect to those Shares.

No assignment or transfer of Restricted Stock Units, whether voluntary or involuntary, by operation of law or otherwise, can be made except by will or the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Corporation.

Notwithstanding the preceding paragraph, you may transfer your Restricted Stock Units to one or more family members (as such term is used in the Plan) or to one or more trusts established solely for the benefit of one or more family members or to one or more partnerships in which the only partners are family members; provided, however, that (i) no such transfer shall be effective unless you deliver reasonable prior notice thereof to the Corporation and such transfer is thereafter effected subject to the specific authorization of, and in accordance with any terms and conditions that shall have been made applicable thereto by, the Committee or the Board, (ii) any such transferee shall be subject to the same terms and conditions hereunder as you are and (iii) such transfer cannot be made for value.

Death or Disability: If your employment terminates due to your death or you become Disabled, as defined below, your outstanding Restricted Stock Units which are outstanding as of the date of your death or Disability shall become immediately 100% vested, provided that you are employed by the Corporation on the date of your death or Disability. The Shares subject to the Restricted Stock Units that become vested pursuant to this Section 7(a) shall be issued to you or your beneficiary or estate within 60 days after the date of your death or Disability. For purposes of this Award Agreement, and notwithstanding the terms of the Plan, you will be considered “Disabled” or to have a “Disability” if you are, by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than 12 months, receiving income replacement benefits for a period of not less than three months under an accident and health plan covering employees of the Corporation.

By Retirement: If your employment terminates after your Retirement Eligible Date for a reason other than Cause, as defined below, your outstanding Restricted Stock Units shall continue to vest in accordance with Section 3 as though your employment had continued through each remaining vesting date. The Shares subject to the Restricted Stock Units that become vested pursuant to this Section 7(b) shall be issued to you within 60 days after the applicable vesting date.

For Other Reasons: Restricted Stock Units which are not vested as of the date of employment termination for reasons other than those specified in Section 7(a) or 7(b) and which have not become vested pursuant to Section 8 shall immediately terminate and shall be forfeited to the Corporation.

Definition of Cause: For purposes of this Award Agreement, “Cause” shall have the meaning described in your employment or severance agreement with the Corporation, or if no such agreements exists, then it shall mean your:

Change in Control: In the event of a Change in Control, all outstanding Restricted Stock Units shall become fully vested and Section 10.1 of the Plan will apply. The Shares subject to the Restricted Stock Units that become vested pursuant to this Section 8 shall be issued to you within 30 days after the date of the Change in Control; provided that if the Change in Control does not constitute a “change in control event,” within the meaning of Section 409A of the Code, then the Restricted Stock Units shall become fully vested as of the date of the Change in Control, but the Shares subject to such Restricted Stock Units shall not be issued to you until the dates on which the Restricted Stock Units otherwise would have become vested and issuable pursuant to Section 3 of this Award Agreement.

Section 409A. The Restricted Stock Units are intended to be exempt from or comply with Section 409A of the Code, and this Award Agreement shall be interpreted and construed accordingly.
