Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Mr. Prescott was awarded 8,960 shares on May 17, 2018. Of the award, 25% vests on the day of the grant (2,240 shares), and the remaining award (6,720 shares) vests ratably on the anniversary date of the award over the following three years.
(2) Mr. Prescott elected to defer 25% of the award that vested immediately on May 17, 2018 (equivalent of 560 shares) into the Piedmont Office Realty Trust, Inc. (the "Issuer") Executive NonQualified Deferred Compensation Plan ("NQDCP") (approved by the Board of Directors of the Issuer on December 5, 2013). A cash contribution approximating the dollar value of the amount to be deferred will be covered by a Rabbi Trust established by the Issuer. Under the terms of the NQDCP, the dollar amount of the deferral is credited to the Rabbi Trust instead of crediting shares to the participant's share account. The investments of the Rabbi Trust will be substantially the same as the investments selected under the Issuer's 401(k) plan, including various mutual funds, but will not include ownership of Issuer common stock. Payouts under the NQDCP will be made only in cash.
(3) In connection with the vesting of 1,680 shares on May 17, 2018, representing shares vested net of deferral into the NQDCP, 493 shares were forfeited by the employee and delivered to the Company to satisfy tax withholding obligations.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
