A.    The Grantee is an employee of TIER REIT, Inc. (the “Company”).

B.    Pursuant to the Company’s 2015 Equity Incentive Plan (as may be amended and supplemented from time to time, the “Plan”), the Company hereby grants to the Grantee the number of Restricted Stock Units specified above, subject to the terms and conditions set forth herein. Each Restricted Stock Unit shall relate to one share of Common Stock of the Company (each, a “Share”). Unless otherwise indicated, capitalized terms used herein but not defined shall have the meanings given to those terms in the Plan.

NOW, THEREFORE, the Company and the Grantee agree as follows:

1.Grant of Restricted Stock Units. The Company hereby grants the Grantee the number of Restricted Stock Units specified above (the “Award”), subject to the following terms and conditions and subject to the provisions of the Plan. The Plan is hereby incorporated herein by reference as though set forth herein in its entirety.

2.    Restrictions on Transfer of Award. This Award may not be sold, transferred, pledged, assigned or otherwise encumbered or disposed of by the Grantee, and any Shares issuable with respect to the Award may not be sold, transferred, pledged, assigned or otherwise encumbered or disposed of until (i) the Restricted Stock Units have vested as provided in Section 3 of this Agreement and (ii) Shares have actually been issued to the Grantee pursuant to Section 6 and in accordance with the terms of the Plan and this Agreement.

3.    Vesting of Restricted Stock Units. Except as otherwise provided below, the restrictions and conditions of Section 2(i) of this Agreement shall lapse as follows:

(i)    The Administrator shall determine during the first 60 days following the end of the Performance Period the number of Restricted Stock Units that shall vest on account of the Company’s Annualized TSR Percentage in accordance with the following table:

(ii)    The Administrator shall determine during the first 60 days following the end of the Performance Period the number of Restricted Stock Units that shall vest on account of the Company’s Index Relative TSR Return in accordance with the following table:

(iii)    The Administrator shall determine during the first 60 days following the end of the Performance Period the number of Restricted Stock Units that shall vest on account of the Company’s Peer Relative TSR Return in accordance with the following table:

(iv)    In the event that a Sale Event (as defined in the Plan) occurs prior to the end of the Performance Period, the Grantee will be deemed to have earned the number of Restricted Stock Units based on the attainment level resulting from the Annualized TSR Percentage, Index Relative TSR Return and Peer Relative TSR Return, each calculated from the first day of the Performance Period through the end of the calendar month immediately preceding the date of the Sale Event pursuant to Sections 3(i), 3(ii) and 3(iii) above, multiplied by (a) in the event such Sale Event is consummated prior to the one-year anniversary of January

1, [2017], a fraction, the numerator of which shall be the number of calendar days from January 1, [2017] to the date of the Sale Event and the denominator of which shall be 365, and (b) in the event such Sale Event is consummated on or after the one-year anniversary of January 1, [2017], the number one. All such earned Restricted Stock Units shall become fully vested upon the consummation of the Sale Event. The foregoing treatment supersedes the treatment of performance awards upon a Sale Event in the Grantee’s Employment Agreement.

4.    Adjustments. Without duplication with the provisions of Section 3 of the Plan, if (i) the Company shall at any time be involved in a merger, consolidation, dissolution, liquidation, reorganization, exchange of shares, sale of all or substantially all of the assets or shares of Common Stock of the Company or a transaction similar thereto, (ii) any stock dividend, stock split, reverse stock split, stock combination, reclassification, recapitalization, or other similar change in the capital structure of the Company, or any distribution to holders of Stock other than ordinary cash dividends, shall occur or (iii) any other event shall occur which in the judgment of the Administrator necessitates action by way of adjusting the terms of this Award, then and in that event, the Administrator shall take such action as shall be necessary in the discretion of the Administrator to maintain the Grantee’s rights hereunder.

5.    Termination of Service.

(i)    Except as otherwise provided herein, if the Grantee’s employment with the Company and its Subsidiaries terminates for any reason prior to the satisfaction of the vesting conditions set forth in Section 3, above, any Restricted Stock Units that have not vested as of such date shall automatically and without notice terminate and be forfeited, and neither the Grantee nor any of his or her successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in such unvested Restricted Stock Units.

(ii)    If the Grantee’s employment is terminated by the Company for reasons other than Cause, the Grantee’s employment terminates on account of death or Disability or the Grantee resigns for Good Reason prior to the end of the Performance Period, subject to the effectiveness of a release in favor of the Company (except in the case of death), the Administrator shall determine the amount of Restricted Stock Units deemed earned based on the Company’s Annualized TSR Percentage, Index Relative TSR Return and Peer Relative TSR Return through the date the Grantee’s employment relationship with the Company is terminated (the “Termination Date”), and the Grantee shall vest in the greater of (x) the number of Restricted Stock Units underlying the Target Award or (y) the number of Restricted Stock Units deemed earned based on the Company’s Annualized TSR Percentage, Index Relative TSR Return and Peer Relative TSR Return through the Termination Date, and if the Termination Date is prior to the one-year anniversary of January 1, [2017], further multiplied by a fraction, the numerator of which shall be the number of calendar days from the Grant Effective Date to the Termination Date and the denominator of which shall be 365.

6.    Issuance of Shares; Forfeiture. The Company shall issue to the Grantee the number of Shares equal to the aggregate number of Restricted Stock Units that have vested pursuant to Section 3 of this Agreement within 30 days thereafter (such date of issuance, the “Issuance Date”). On the Issuance Date, the Company shall also issue to the Grantee a number

of Shares determined by multiplying the Dividend Shares by the number of Shares issued to the Grantee pursuant to the first sentence of this Section 6.

7.    Defined Terms. The following terms shall have the following respective meanings:

(ii)    “Annualized TSR Percentage” means the compounded annual growth rate, expressed as a percentage (rounded down to the nearest tenth of a percent (0.1%)), in the value per Share during the Performance Period due to the appreciation in the price per Share and dividends paid during such period, assuming dividends are reinvested. Where “D” is the value of all dividends paid to a shareholder of record with respect to one Share during the Performance Period at the end of the Performance Period after being reinvested and N is the number of 12 month periods that have elapsed between the first day of the Performance Period and the last day of the Performance Period (which may not be a full integer if computed in connection with a Sale Event or a termination of employment under Section 5(ii)) the Annualized TSR Percentage is calculated as follows:

(ix)    “Fair Market Value” means, as of any given date, the fair market value of a security which shall be the closing sale price reported for such security on the principal stock exchange or, if applicable, any other national exchange on which the security is traded or admitted to trading on such date on which a sale was reported.

After this ranking, the percentile performance of the Company relative to the Index Companies will be determined as follows:
