Ladies and Gentlemen:

Piedmont Operating Partnership, LP, a Delaware limited partnership (the “Operating Partnership”), proposes to issue and sell to the several Underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”),

$400,000,000 principal amount of its 9.250% Senior Notes due 2028 (the “Securities”). The Securities will be issued pursuant to an Indenture, dated as of March 6, 2014 (the “Base Indenture”), among the Operating Partnership, Piedmont Office Realty Trust, Inc., a Maryland corporation (the “Company”), and U.S. Bank Trust Company, National Association (as successor to U.S. Bank National Association), as trustee (the “Trustee”), as amended by a Supplemental Indenture to be dated as of July 20, 2023 (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), and will be guaranteed on a senior unsecured basis by the Company (the “Guarantee”) (the Company, together with the Operating Partnership, the “Transaction Entities”). This agreement by and among the Transaction Entities and the Underwriters shall be referred to as this “Agreement.”

The Transaction Entities hereby confirm their agreement with the several Underwriters concerning the purchase and sale of the Securities, as follows:

1. Registration Statement. The Operating Partnership has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form S-3 (File No. 333-266389), including a prospectus, relating to the Securities. Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means each prospectus included in such registration statement (and any amendments thereto) before it becomes effective, any prospectus filed with the Commission pursuant to Rule 424(a) under the Securities Act and the prospectus included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Securities. Any reference in this Agreement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be, and any reference to “amend”, “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to 3:10 P.M., the time when sales of the Securities were first made (the “Time of Sale”), the Company and the Operating Partnership had prepared the following information (collectively, the “Time of Sale Information”): a Preliminary Prospectus dated July 18, 2023 and each “free writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex C hereto.

2. Purchase of the Securities by the Underwriters.

(a) The Operating Partnership agrees to issue and sell the Securities to the several Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Operating Partnership the respective principal amount of Securities set forth opposite such Underwriter’s name in Schedule 1 hereto at a price equal to 98.40% of the principal amount thereof plus accrued interest, if any, from July 20, 2023 to the Closing Date (as defined below). The Operating Partnership will not be obligated to deliver any of the Securities except upon payment for all the Securities to be purchased as provided herein.

(b) The Operating Partnership understands that the Underwriters intend to make a public offering of the Securities as soon after the effectiveness of this Agreement as in the judgment of the Representatives is advisable, and initially to offer the Securities on the terms set forth in the Time of Sale Information. The Operating Partnership acknowledges and agrees that the Underwriters may offer and sell Securities to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Securities purchased by it to or through any Underwriter.

(c) Payment for and delivery of the Securities will be made at the offices of Hogan Lovells US LLP, 555 Thirteenth Street, NW, Washington, DC 20004 at 10:00 A.M., New York City time, on July 20, 2023, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representatives and the Company may agree upon in writing. The time and date of such payment and delivery is referred to herein as the “Closing Date.”

(d) Payment for the Securities shall be made by wire transfer in immediately available funds to the account(s) specified by the Operating Partnership to the Representatives against delivery to the nominee of The Depository Trust Company (“DTC”), for the account of the Underwriters, of one or more global notes representing the Securities (collectively, the “Global Note”), with any transfer taxes payable in connection with the sale of the Securities duly paid by the Operating Partnership. The Global Note will be made available for inspection by the Representatives not later than 1:00 P.M., New York City time, on the business day prior to the Closing Date.

(e) The Transaction Entities acknowledge and agree that each Underwriter is acting solely in the capacity of an arm’s length commercial contractual counterparty to the Transaction Entities with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and that the purchase and sale of the Securities pursuant to this Underwriting Agreement does not constitute a recommendation, investment advice, or solicitation of any action by the Underwriters. Additionally, neither the Representatives nor any other Underwriter is advising the Transaction Entities or any other person as to any legal, tax, investment, accounting, financial or regulatory matters in any jurisdiction. In connection with the offering of the Securities and the process leading thereto, each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Transaction Entities or any of their Subsidiaries or their stockholders, creditors, employees or any other party. No Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Transaction Entities with respect to the offering of the Securities or the processes leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Transaction Entities or any of their Subsidiaries on other matters) and no Underwriter has any obligation to the Transaction Entities with respect to the offering of Securities except the obligations expressly set forth in this

3

Agreement. The Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Transaction Entities. The Transaction Entities shall consult with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and neither the Representatives nor any other Underwriter shall have any responsibility or liability to either of the Transaction Entities with respect thereto. Any review by the Representatives or any Underwriter of the Transaction Entities, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Representatives or such Underwriter and shall not be on behalf of either of the Transaction Entities or any other person.

3. Representations and Warranties of the Transaction Entities. Each of the Transaction Entities jointly and severally represents and warrants to each Underwriter that:

(a) Preliminary Prospectus. No order preventing or suspending the use of any Preliminary Prospectus has been issued by the Commission, and each Preliminary Prospectus, at the time of filing thereof, complied in all material respects with the Securities Act and did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that the Transaction Entities make no representation or warranty with respect to any statements or omissions made in reliance upon and in conformity with information relating to any Underwriter furnished to the Transaction Entities in writing by such Underwriter through the Representatives expressly for use in any Preliminary Prospectus.

No statement of material fact included in the Prospectus has been omitted from the Time of Sale Information and no statement of material fact included in the Time of Sale Information that is required to be included in the Prospectus has been omitted therefrom.

(c) Issuer Free Writing Prospectus. The Transaction Entities (including their agents and representatives, other than the Underwriters in their capacity as such) have not prepared, made, used, authorized, approved or referred to and will not prepare, make, use, authorize, approve or refer to any “written communication” (as defined in Rule 405 under the Securities Act) that constitutes an offer to sell or solicitation of an offer to buy the Securities (each such communication by the Transaction Entities or their agents and representatives (other than a communication referred to in clauses (i), (ii) and (iii) below) an “Issuer Free Writing Prospectus”) other than (i) any document not constituting a prospectus pursuant to Section 2(a)(10)(a) of the Securities Act or Rule 134 under the Securities Act, (ii) the Preliminary Prospectus, (iii) the Prospectus, (iv) the documents listed on Annex C hereto as constituting part of the Time of Sale Information and (v) any electronic road show or other written communications, in each case approved in writing in

The Registration Statement is an “automatic shelf registration statement” as defined under Rule 405 of the Securities Act that has been filed with the Commission not earlier than three years prior to the date hereof; and no notice of objection of the Commission to the use of such registration statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act has been received by the Operating Partnership. No order suspending the effectiveness of the Registration Statement has been issued by the Commission and no proceeding for that purpose or pursuant to Section 8A of the Securities Act against the Operating Partnership or related to the offering has been initiated or, to the knowledge of the Transaction Entities, threatened by the Commission; as of the applicable effective date of the Registration Statement and any amendment thereto, the Registration Statement complied and will comply in all material respects with the Securities Act and the Trust Indenture Act of 1939, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Trust Indenture Act”), and did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading; and as of the date of the Prospectus and any amendment or supplement thereto and as of the Closing Date, the Prospectus will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that the Operating Partnership makes no representation or warranty with respect to (i) that part of the Registration Statement that constitutes the Statement of Eligibility and Qualification (Form T-1) of the Trustee under the Trust Indenture Act or (ii) any statements or omissions made in reliance upon and in conformity with information relating to any Underwriter furnished to the Operating Partnership in writing by such Underwriter through the Representatives expressly for use in the Registration Statement and the Prospectus and any amendment or supplement thereto.

7. Indemnification and Contribution.

(a) Indemnification of the Underwriters. The Transaction Entities jointly and severally agree to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses reasonably incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, (ii) or any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Transaction Entities in writing by such Underwriter through the Representatives expressly for use therein.

(b) Indemnification of the Transaction Entities. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless each of the Transaction Entities and each of their respective directors and officers who signed the Registration Statement and each person, if any, who controls the Company or the Operating Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Transaction Entities in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed

23

that the only such information consists of the following paragraphs in the Preliminary Prospectus and the Prospectus: first and second sentences of the third paragraph, the third sentence of the seventh paragraph and the eighth paragraph, in each case under the heading of “Underwriting”, in each of the Preliminary Prospectus and the Prospectus.

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Company, the Operating Partnership, their respective directors and officers who signed the Registration Statement and any control persons of the Company and the Operating Partnership shall be designated in writing by the Transaction Entities. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be

24

liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraph (a) or (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Transaction Entities on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Transaction Entities on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Transaction Entities on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Transaction Entities on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Operating Partnership or the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Transaction Entities and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that

25

such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company and the Operating Partnership, if after the execution and delivery of this Agreement and on or prior to the Closing Date: (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange or the over-the-counter market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

10. Defaulting Underwriter.

(a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Transaction Entities on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Transaction Entities shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Transaction Entities may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Transaction Entities or counsel for the Underwriters may be necessary in the Registration Statement, the Time of Sale Information and the Prospectus or in any other document or arrangement, and the Operating Partnership agrees to promptly prepare any amendment or supplement to the Registration Statement, the Time of Sale Information and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

26

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Transaction Entities as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Operating Partnership shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Transaction Entities as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Operating Partnership shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Operating Partnership or the Company, except that the Operating Partnership and the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof, other than in the case of expenses of any defaulting Underwriter, and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company, the Operating Partnership or any non-defaulting Underwriter for damages caused by its default.

11. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Transaction Entities jointly and severally agree to pay or cause to be paid all costs and expenses incident to the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Transaction Entities’ counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters not to exceed $10,000); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering of the Securities by, the Financial Industry Regulatory Authority, and the approval of the Securities for book-entry transfer by DTC; and (ix) all expenses incurred by the Transaction Entities in connection with any “road show” presentation to potential investors.

27

(b) If (i) this Agreement is terminated pursuant to Section 9, (ii) the Operating Partnership for any reason fails to tender the Securities for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Securities for any reason permitted under this Agreement, the Transaction Entities jointly and severally agree to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

12. Qualified Financial Contract. In the event that any party to this Agreement is not a company (i) that is incorporated or organized under the laws of the United States or any state thereof or (ii) with its principal place of business in the United States or any State thereof, then the following provisions shall be applicable to this Agreement and any transaction hereunder:

(a) In the event that such party that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such party that is a Covered Entity of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any interest and obligation in or under this Agreement, were governed by the laws of the United States or a state of the United States.

(b) In the event that such party that is a Covered Entity or a BHC Act Affiliate of the Underwriters that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, any Default Rights under this Agreement that may be exercised against such party that is a Covered Entity are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime.

For purposes of this Section 12, the following terms shall have the following meaning:

“BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k) or 1813(w), as applicable.

“Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable.

Annex A–Page 1

(7) The Indenture has been duly authorized, executed and delivered by the Operating Partnership and constitutes a valid and legally binding agreement of the Company and the Operating Partnership enforceable against the Company and the Operating Partnership in accordance with its terms, subject, as to enforcement of remedies, to bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and similar laws affecting the rights and remedies of creditors generally and the effects of general principles of equity; and the Indenture conforms in all material respects with the requirements of the Trust Indenture Act and the rules and regulations of the Commission applicable to an indenture that is qualified thereunder.

W I T N E S S E T H:

WHEREAS, the Issuer has delivered to the Trustee an Indenture, dated as of March 6, 2014 (the “Base Indenture”, as supplemented by this Fourth Supplemental Indenture, the “Indenture”), providing for the issuance by the Issuer from time to time of Securities in one or more series;

WHEREAS, Section 301 of the Base Indenture provides that various matters with respect to any series of Securities issued under the Base Indenture may be established in an indenture supplemental to the Base Indenture;

WHEREAS, each of the Issuer and the Guarantor desires to execute this Fourth Supplemental Indenture to establish the form and to provide for the issuance of a series of the Issuer’s senior notes designated as its 9.250% Senior Notes due 2028 (the “Notes”), in an initial aggregate principal amount of $400,000,000;

WHEREAS, the Board of Directors of the Guarantor has duly adopted resolutions authorizing the Issuer and the Guarantor to execute and deliver this Fourth Supplemental Indenture; and

WHEREAS, all of the other conditions and requirements necessary to make this Fourth Supplemental Indenture, when duly executed and delivered, a valid and binding agreement in accordance with its terms and for the purposes herein expressed, have been performed and fulfilled.

NOW, THEREFORE, for and in consideration of the premises and the purchase of the Notes provided for herein by the Holders thereof, it is mutually covenanted and agreed, for the equal and proportionate benefit of all Holders of Notes, as follows:

ARTICLE I

RELATION TO BASE INDENTURE; DEFINITIONS

Section 1.01. Relation to Base Indenture. This Fourth Supplemental Indenture constitutes an integral part of the Base Indenture. Notwithstanding any other provision of this Fourth Supplemental Indenture, all provisions of this Fourth Supplemental Indenture are expressly and solely for the benefit of the Holders of the Notes and any such provisions shall not be deemed to apply to any other Securities issued under the Base Indenture and shall not be deemed to amend, modify or supplement the Base Indenture for any purpose other than with respect to the Notes.

1

The Base Indenture, as supplemented by this Fourth Supplemental Indenture, is referred to herein as the “Indenture.”

Section 1.02. Definitions. For all purposes of this Fourth Supplemental Indenture, except as otherwise expressly provided for or unless the context otherwise requires:

(1) Capitalized terms used but not defined herein shall have the respective meanings assigned to them in the Base Indenture; and

(2) All references herein to Articles and Sections, unless otherwise specified, refer to the corresponding Articles and Sections of this Fourth Supplemental Indenture as they amend or supplement the Base Indenture, and not the Base Indenture or any other document.

“Additional Notes” means additional Notes (other than the Initial Notes) issued under the Base Indenture in accordance with the provisions hereof, as part of the same series as the Initial Notes.

“Consolidated EBITDA” means, for any period of time, without duplication, consolidated net income (loss) of the Guarantor and the Subsidiaries plus amounts which have been deducted and minus amounts which have been added for, without duplication:

(a) Interest Expense;

(b) depreciation and amortization as set forth in the Consolidated Financial Statements of the Guarantor;

(c) provision for taxes based on income or profits;

(d) non-recurring or other unusual items, as determined by the Guarantor in good faith (including, without limitation, all prepayment penalties and costs or fees incurred in connection with any debt financing or amendment thereto, acquisition, disposition, recapitalization or similar transaction (regardless of whether such transaction is completed) and amounts paid in connection with casualty losses and litigation settlements and any corresponding recovery of insurance for such losses or settlements, other than amounts received pursuant to business interruption insurance);

(e) extraordinary items;

(f) noncontrolling interests of the Guarantor and the Subsidiaries;

(g) non-cash swap ineffectiveness charges or income or expense attributable to transactions involving derivative instruments that do not qualify for hedge accounting in accordance with GAAP;

(h) gains or losses on dispositions of depreciable real estate investments, property valuation losses and impairment charges;

2

(i) any impact from a change in accounting policy resulting in a non-cash charge;

(j) increases in deferred taxes; and

(k) amortization of deferred financing costs and other deferred charges.

For such period, amounts will be determined on a consolidated basis in accordance with GAAP (to the extent GAAP is applicable).

“Consolidated Financial Statements” means, with respect to any Person, collectively, the consolidated financial statements and notes to those financial statements of that Person and its subsidiaries prepared in accordance with GAAP.

“Debt” means, as of any date, without duplication, any of the Guarantor’s indebtedness or that of any Subsidiary, whether or not contingent, in respect of:

(a) borrowed money evidenced by bonds, notes, debentures or similar instruments whether or not such indebtedness is secured by any Lien existing on property owned by the Guarantor or any Subsidiary;

(b) indebtedness for borrowed money of a Person other than the Guarantor, or a Subsidiary, which is secured by any Lien on property owned by the Guarantor or any Subsidiary, to the extent of the lesser of (i) the amount of indebtedness so secured, and (ii) the fair market value (determined in good faith by the Board of Directors of the Guarantor or a duly authorized committee thereof) of the property subject to such Lien;

(c) the reimbursement obligations, contingent or otherwise, in connection with any letters of credit actually issued or amounts representing the balance deferred and unpaid of the purchase price of any property or services (and, for the avoidance of doubt, after the closing of the acquisition of any property or the completion of services under any services contract), except any such balance that constitutes an accrued expense or trade payable; or

(d) any lease of property by the Guarantor or any Subsidiary as lessee which is required to be reflected on the Guarantor’s consolidated balance sheet as a financing lease in accordance with GAAP;

provided, however, that the term “Debt” under clause (d) of this definition will not include operating lease liabilities on the balance sheet of the Guarantor or of any Subsidiary acting as lessee in accordance with GAAP; and provided further, that the term “Debt” under this definition will not include any such indebtedness that has been the subject of an “in substance” defeasance in accordance with GAAP. Debt also includes, to the extent not otherwise included, any obligation of the Guarantor or any Subsidiary to be liable for, or to pay, as obligor, guarantor or otherwise (other than for purposes of collection in the ordinary course of business), indebtedness of another Person (other than the Guarantor or any of the Subsidiaries) of the type described in clauses (a)-(d) of this definition.

3

“Incur” means, with respect to any Debt or other obligation of any Person, to create, assume, guarantee or otherwise become liable in respect of the Debt or other obligation, and “Incurrence” and “Incurred” have the meanings correlative to the foregoing. Debt or any other obligation of the Guarantor or any Subsidiary will be deemed to be Incurred by the Guarantor or such Subsidiary whenever the Guarantor or such Subsidiary shall create, assume, guarantee or otherwise become liable in respect thereof. Debt or any other obligation of a Subsidiary existing prior to the time it became a Subsidiary will be deemed to be Incurred upon such Subsidiary becoming a Subsidiary; and Debt or other obligation of a Person existing prior to a merger or consolidation of such Person with the Guarantor or any Subsidiary in which such Person is the successor to the Guarantor or such Subsidiary will be deemed to be Incurred upon the consummation of such merger or consolidation. Any issuance or transfer of capital stock that results in Debt constituting Intercompany Debt being held by a Person other than the Guarantor or any Subsidiary or any sale or other transfer of any Debt constituting Intercompany Debt to a Person that is not the Guarantor or a Subsidiary, will be deemed, in each case, to be an Incurrence of Debt that is not Intercompany Debt at the time of such issuance, transfer or sale, as the case may be.

“Final Maturity Date” means July 20, 2028.

“Initial Notes” means the first $400,000,000 aggregate principal amount of Notes issued under this Fourth Supplemental Indenture on the date hereof.

“Intercompany Debt” means, as of any date, Debt to which the only parties are the Guarantor or any Subsidiary.

“Interest Expense” means, for any period of time, without duplication, the aggregate amount of interest recorded in accordance with GAAP for such period of time by the Guarantor and the Subsidiaries, but excluding: (a) interest reserves funded from the proceeds of any loan; (b) amortization of deferred financing costs; (c) prepayment penalties; and (d) non-cash swap ineffectiveness charges or charges attributable to transactions involving derivative instruments that do not qualify for hedge accounting in accordance with GAAP; and including, without limitation or duplication, effective interest in respect of original issue discount as determined in accordance with GAAP.

“Par Call Date” means June 20, 2028 (one month prior to the Final Maturity Date).

“Rating Agency” means (1) each of Moody’s and S&P; and (2) if either of Moody’s or S&P ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of the Issuer’s control, a Substitute Rating Agency.

“Secured Debt” means, as of any date, that amount of Debt as of that date that is secured by a Lien on properties or other assets of the Guarantor or any of the Subsidiaries.

“Substitute Rating Agency” means a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) under the Exchange Act, selected by the Issuer (as certified by a resolution of the Issuer’s Board of Directors) as a replacement agency for Moody’s or S&P, or both, as the case may be.

4

“Total Assets” means, as of any date, without duplication, the sum of: (1) Undepreciated Real Estate Assets; (2) cash, cash equivalents and marketable securities of the Guarantor and the Subsidiaries, determined in accordance with GAAP; (3) notes and mortgages receivable, calculated as the lesser of (i) the aggregate amount of principal under such note or mortgage that will be due and payable to the Guarantor or the Subsidiaries and (ii) the purchase price paid by the Guarantor or the Subsidiaries to acquire such note or mortgage; and (4) all of the Guarantor’s other assets and the assets of the Subsidiaries (excluding intangibles and accounts receivable) determined on a consolidated basis in accordance with GAAP.

“Total Unencumbered Assets” means, as of any date, those Total Assets not securing any amount of Secured Debt; provided, however, that all investments by the Guarantor and the Subsidiaries in unconsolidated joint ventures, unconsolidated limited partnerships, unconsolidated limited liability companies and other unconsolidated entities shall be excluded from Total Unencumbered Assets to the extent that such investments would have otherwise been included. For the avoidance of doubt, cash held by a “qualified intermediary” in connection with proposed like-kind exchanges pursuant to Section 1031 of the Internal Revenue Code of 1986, as amended, which may be classified as “restricted” for GAAP purposes, will nonetheless be considered Total Assets not securing any amount of Secured Debt, so long as the Guarantor or a Subsidiary has the right (i) to direct the qualified intermediary to return such cash to the Guarantor or a Subsidiary if and when the Guarantor fails to identify or acquire the proposed like-kind property or at the end of the 180-day replacement period or (ii) direct the qualified intermediary to use such cash to acquire like-kind property.

“Treasury Rate” means, with respect to any Redemption Date for the Notes, a yield determined by the Issuer in accordance with the following:

(a) The Treasury Rate shall be determined by the Issuer after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities — Treasury constant maturities — Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields — one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life — and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date; and

5

(b) If on the third Business Day preceding the Redemption Date, H.15 TCM is no longer published, the Issuer shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this clause (b), the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

“Undepreciated Real Estate Assets” means, as of any date, the cost (original cost plus capital improvements) of real estate assets of the Guarantor and its Subsidiaries on such date, before depreciation and amortization, determined on a consolidated basis in accordance with GAAP; provided, however, that “Undepreciated Real Estate Assets” shall not include the right of use assets associated with an operating lease in accordance with GAAP.

“Unsecured Debt” means, as of any date, that amount of Debt as of that date that is not Secured Debt.

ARTICLE II

TERMS OF THE SECURITIES

Section 2.01. Title of the Securities. The Notes shall be known and designated as the “9.250% Senior Notes due 2028.”

Section 2.02. Limitation on Initial Aggregate Principal Amount; Further Issuances. The aggregate principal amount of Notes which may be authenticated and delivered under the Base Indenture is unlimited; provided, that upon initial issuance on the date hereof the aggregate principal amount of Notes outstanding shall not exceed $400,000,000, except for Notes issued upon a redemption in part, exchange or registration of transfer of other Notes as provided herein and except as provided in Sections 305, 306, 307 and 1107 of the Base Indenture. The Issuer may, without the consent of or notice to the Holders of Notes, issue Additional Notes from time to time in the future with the same terms and provisions as the Initial Notes, except for any difference in

6

issue price, Interest accrued prior to the issue date and the first Interest Payment Date of those Additional Notes; provided, that such Additional Notes shall be treated as part of the same issue as and fungible with the Initial Notes for United States federal income tax purposes and shall carry the same right to receive accrued and unpaid Interest as the other Notes then outstanding; provided, however, that, notwithstanding the foregoing, (i) if the Additional Notes are not fungible with the Notes for United States federal income tax purposes, the Additional Notes will have a separate CUSIP number and (ii) if the Issuer has effected legal defeasance or covenant defeasance with respect to the Notes pursuant to Section 402 of the Base Indenture or has effected satisfaction and discharge with respect to the Notes pursuant to Section 401 of the Base Indenture, no Additional Notes may be issued. The Initial Notes and any such Additional Notes shall constitute a single series of debt Securities, and in circumstances in which the Indenture provides for the Holders of Notes to vote or take any action, the Holders of Initial Notes and any such Additional Notes will vote or take that action as a single class.

Section 2.03. Maturity. The final Maturity Date of the Notes on which the principal thereof is due and payable shall be July 20, 2028.

Section 2.04. Interest and Interest Rates. The principal of the Notes shall bear Interest at the rate of 9.250% per annum from and including July 20, 2023 or from the most recent date to which Interest has been paid or duly provided for, payable semiannually in arrears on January 20 and July 20 (each, an “Interest Payment Date” for the Notes) of each year, commencing January 20, 2024, to the Persons in whose names such Notes (or one or more Predecessor Securities) are registered at the close of business on the January 5 or July 5, respectively, immediately prior to such Interest Payment Dates (each, a “Regular Record Date” for the Notes) regardless of whether such Regular Record Date is a Business Day. Interest on the Notes will be computed on the basis of a 360-day year of twelve 30-day months. If any principal of, or premium, if any, or Interest on, any of the Notes is not paid when due, then such overdue principal and, to the extent permitted by law, such overdue premium or Interest, as the case may be, shall bear Interest until paid or until such payment is duly provided for at the rate of 9.250% per annum.

Section 2.05. Interest Rate Adjustment of the Notes Based on Certain Rating Events.

(a) The Interest rate payable on the Notes will be subject to adjustment from time to time if either Moody’s Investors Services Inc. and its successors (“Moody’s”) or S&P Global Ratings and its successors (“S&P”) (or, in either case, a Substitute Rating Agency) downgrades (or subsequently upgrades) its rating assigned to the Notes as set forth in this Section 2.05.

(b) If the rating of the Notes from one or both of Moody’s or S&P (or, if applicable, any Substitute Rating Agency) is decreased to a rating set forth in either of the immediately following tables, the Interest rate on the Notes will increase from the Interest rate set forth in this Fourth Supplemental Indenture by an amount equal to the sum of the percentages per annum set forth in the following tables opposite those ratings:

7

The Issuer will notify the Trustee in writing of any such ratings downgrade and any applicable Interest rate adjustment to be applied to the Notes.

(c) For purposes of making adjustments to the Interest rate on the Notes, the following rules of interpretation will apply:

(1) if at any time fewer than two Rating Agencies provide a rating on the Notes for reasons not within the Issuer’s control, (i) the Issuer will use commercially reasonable efforts to obtain a rating on the Notes from a Substitute Rating Agency for purposes of determining any increase or decrease in the Interest rate on the Notes pursuant to the tables above, (ii) such Substitute Rating Agency will be substituted for the last Rating Agency to provide a rating on the Notes but which has since ceased to provide such rating, (iii) the relative ratings scale used by such Substitute Rating Agency to assign ratings to senior unsecured debt will be determined in good faith by an independent investment banking institution of national standing appointed by the Issuer and, for purposes of determining the applicable ratings included in the applicable table above with respect to such Substitute Rating Agency, such ratings shall be deemed to be the equivalent ratings used by Moody’s or S&P, as applicable, in such table, and (iv) the Interest rate on the Notes will increase or decrease, as the case may be, such that the Interest rate equals the Interest rate with respect to the Notes set forth in this Fourth Supplemental Indenture plus the appropriate percentage, if any, set forth opposite the rating from such Substitute Rating Agency in the applicable table above (taking into account the provisions of clause (iii) above) (plus any applicable percentage resulting from a decreased rating by the other Rating Agency);

(2) for so long as only one Rating Agency (or Substitute Rating Agency, if applicable) provides a rating on the Notes, any increase or decrease in the Interest rate on the Notes necessitated by a reduction or increase in the rating by that Rating Agency shall be twice the applicable percentage set forth in the applicable table above;

(3) if both Rating Agencies cease to provide a rating of the Notes for any reason, and no Substitute Rating Agency has provided a rating on the Notes, the Interest rate on the Notes will increase to, or remain at, as the case may be, 2.00% per annum above the Interest rate on the Notes prior to any such adjustment;

8

(4) if Moody’s or S&P ceases to rate the Notes or make a rating of the Notes publicly available for reasons within the Issuer’s control, the Issuer will not be entitled to obtain a rating from a Substitute Rating Agency and the increase or decrease in the Interest rate on the Notes shall be determined in the manner described above as if either only one or no Rating Agency provides a rating on the Notes, as the case may be;

(5) each Interest rate adjustment required by any decrease or increase in a rating as set forth above, whether occasioned by the action of Moody’s or S&P (or, in either case, any Substitute Rating Agency), shall be made independently of (and in addition to) any and all other Interest rate adjustments occasioned by the action of the other Rating Agency;

(6) in no event will (i) the Interest rate on the Notes be reduced to below the Interest rate on the Notes at the time of issuance or (ii) the total increase in the Interest rate on the Notes exceed 2.00% above the Interest rate payable on the Notes on the date of their initial issuance; and

(7) subject to clauses (3) and (4) above, no adjustment in the Interest rate on the Notes shall be made solely as a result of a Rating Agency ceasing to provide a rating of the Notes.

(d) If at any time the Interest rate on the Notes has been adjusted upward and either of the Rating Agencies subsequently increases its rating of the Notes, the Interest rate on the Notes will again be adjusted (and decreased, if appropriate) such that the Interest rate on the Notes equals the original Interest rate payable on the Notes prior to any adjustment plus (if applicable) an amount equal to the sum of the percentages per annum set forth opposite the ratings in the tables above with respect to the ratings assigned to the Notes (or deemed assigned) at that time, all calculated in accordance with the rules of interpretation set forth above. If Moody’s or any Substitute Rating Agency subsequently increases its rating on the Notes to “Baa3” (or its equivalent if with respect to any Substitute Rating Agency) or higher and S&P or any Substitute Rating Agency subsequently increases its rating on the Notes to “BBB-” (or its equivalent if with respect to any Substitute Rating Agency) or higher, the Interest rate on the Notes will be decreased to the Interest rate on the Notes prior to any adjustments made pursuant to this section.

(e) Any Interest rate increase or decrease described above will take effect from the first day of the Interest period following the period in which a rating change occurs requiring an adjustment in the Interest rate. If either Rating Agency changes its rating of the Notes more than once during any particular Interest period, the last such change by such Rating Agency to occur will control in the event of a conflict for purposes of any increase or decrease in the Interest rate with respect to the Notes.

(f) The Interest rate on the Notes will permanently cease to be subject to any adjustment described above (notwithstanding any subsequent decrease in the ratings by either Rating Agency) if the Notes are rated “Baa1” or higher by Moody’s (or its equivalent if with respect to any Substitute Rating Agency) and “BBB+” or higher by S&P (or its equivalent if with respect to any Substitute Rating Agency), in each case with a stable or positive outlook.

9

(g) If the Interest rate on the Notes is increased as described above, the term “Interest,” as used with respect to the Notes, will be deemed to include any such additional Interest unless the context otherwise requires.

Section 2.06. Place of Payment. The City of Boston is hereby designated as a Place of Payment for the Notes. The place where the principal of and premium, if any, and Interest (including the Redemption Price) on the Notes shall be payable, where Notes may be surrendered for the registration of transfer or exchange, and where notices or demands to or upon the Issuer or the Guarantor in respect of the Notes and the Indenture may be served shall be the office or agency maintained by the Issuer for such purpose in the City of Boston, which shall initially be the Corporate Trust Office.

Section 2.10. Election of Currency.

ARTICLE III

REDEMPTION OF NOTES

Section 3.01. Redemption of Notes.

(a) Prior to the Par Call Date, the Issuer may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (with respect to the Notes to be redeemed on any Redemption Date, the “Redemption Price”) (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (1) (a) the sum of the present values of the remaining scheduled payments of principal and Interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points less (b) Interest accrued to the Redemption Date, and (2) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid Interest thereon to, but not including, the Redemption Date.

11

(b) On or after the Par Call Date, the Issuer may redeem the Notes, in whole or in part, at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid Interest thereon to, but not including, the Redemption Date.

(c) Notwithstanding the foregoing, the Issuer shall not redeem the Notes pursuant to Section 3.01(a) on any date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded or cured on or prior to such date.

Section 3.02. Notice of Optional Redemption; Selection of Notes. In case the Issuer shall desire to exercise the right to redeem all or, as the case may be, any part of the Notes pursuant to Section 3.01, it shall fix a date for redemption and it or, at its written request received by the Trustee not fewer than two Business Days prior (or such shorter period of time as may be acceptable to the Trustee) to the date the notice of redemption is to be mailed, the Trustee in the name of and at the expense of the Issuer, shall mail or electronically deliver (or otherwise transmit in accordance with the Depositary’s procedures), or cause to be mailed or electronically delivered (or otherwise transmitted in accordance with the Depositary’s procedures), a notice of such redemption at least 10 days but not more than 60 days prior to the Redemption Date to each Holder of Notes so to be redeemed; provided that if the Issuer makes such request of the Trustee, it shall, together with such request, also give written notice of the Redemption Date to the Trustee; provided further that the text of the notice shall be prepared by the Issuer. Each such notice of redemption shall specify: (i) the aggregate principal amount of Notes to be redeemed, (ii) the CUSIP number or numbers and ISIN number or numbers of the Notes being redeemed, (iii) the Redemption Date (which shall be a Business Day), (iv) the Redemption Price (or the method of calculating such Redemption Price) at which Notes are to be redeemed, (v) the place or places of payment and that payment will be made upon presentation and surrender of such Notes and (vi) that Interest accrued and unpaid to, but excluding, the Redemption Date will be paid as specified in said notice, and that, unless the Issuer defaults in the payment of the Redemption Price, on and after the Redemption Date Interest will cease to accrue on the Notes or portions thereof called for redemption. If fewer than all the Notes are to be redeemed, the notice of redemption shall identify the Notes to be redeemed (including CUSIP numbers, if any). The notice, if mailed, electronically delivered or otherwise transmitted in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.

Whenever any Notes are to be redeemed, the Issuer will give the Trustee written notice of the Redemption Date, together with an Officers’ Certificate as to the aggregate principal amount of Notes to be redeemed not fewer than 30 days (or such shorter period of time as may be acceptable to the Trustee) prior to the Redemption Date.

12

On or prior to the Redemption Date specified in the notice of redemption given as provided in this Section 3.02, the Issuer will deposit with the Paying Agent (other than the Issuer or the Guarantor acting as its own Paying Agent) an amount of money in immediately available funds sufficient to redeem on the Redemption Date all the Notes (or portions thereof) so called for redemption at the appropriate Redemption Price, together with accrued and unpaid Interest, if any, on the Notes or portions thereof to be redeemed; provided that if such payment is made on the Redemption Date, it must be received by the Paying Agent, by 10:00 a.m., New York City time, on such date. The Issuer shall be entitled to retain any interest, yield or gain on amounts deposited with the Paying Agent pursuant to this Section 3.02 in excess of amounts required hereunder to pay the Redemption Price, together with accrued and unpaid Interest, if any, on the Notes or portions thereof to be redeemed.

In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another Depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the Depositary.

Section 3.03. Payment of Notes Called for Redemption by the Issuer. If notice of redemption has been given as provided in Section 3.02, the Notes or portion of Notes with respect to which such notice has been given shall become due and payable on the Redemption Date and at the place or places stated in such notice at the Redemption Price, together with accrued and unpaid Interest, if any, thereon, and if the Paying Agent holds funds sufficient to pay the Redemption Price of such Notes, together with accrued and unpaid Interest, if any, thereon, then, on and after such Redemption Date (a) such Notes will cease to be outstanding and (b) Interest on the Notes or portion of Notes so called for redemption shall cease to accrue and, except as provided in Article 15 of the Base Indenture, such Notes shall cease to be entitled to any benefit under the Indenture, and the Holders thereof shall have no right in respect of such Notes except the right to receive the Redemption Price thereof, together with accrued and unpaid Interest, if any, thereon. On presentation and surrender of such Notes at a place of payment in said notice specified, the said Notes or the specified portions thereof shall be paid and redeemed by the Issuer at the Redemption Price, together with Interest accrued thereon, if any, to, but excluding, the Redemption Date.

Upon presentation of any Note redeemed in part only, the Issuer shall execute and the Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of the Issuer, a new Note or Notes, of authorized denominations, in principal amount equal to the unredeemed portion of the Notes so presented.

Prior to the applicable Redemption Date, the Issuer shall provide to the Trustee an Officers’ Certificate that shall set forth the applicable Redemption Price and the calculation thereof in reasonable detail. The Issuer’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error. The Trustee shall be under no duty to inquire into, may conclusively presume the correctness of, and shall be fully protected in acting upon the Issuer’s calculation of the Redemption Price. The Trustee shall provide such calculation to any Holder upon request.

(a) Total Assets of the Guarantor and its Subsidiaries as of the end of the fiscal quarter covered in the Guarantor’s annual or quarterly report most recently furnished to the Holders or filed with the Commission, as the case may be; and

(b) the aggregate purchase price of any real estate assets, notes or mortgages receivable acquired, and the aggregate amount of any securities offering proceeds received (to the extent such proceeds were not used to acquire real estate assets, notes or mortgages receivable or used to reduce Debt), by the Guarantor or any Subsidiary since the end of such fiscal quarter, including the proceeds obtained from the Incurrence of such additional Debt.

Section 4.02. Limitation on Secured Debt. The Guarantor will not, and will not permit any Subsidiary to, Incur any Secured Debt (other than Intercompany Debt that is subordinate in right of payment to the Notes) if, immediately after giving effect to the Incurrence of such Secured Debt and the application of the proceeds from such Debt on a pro forma basis, the aggregate principal amount of all outstanding Secured Debt of the Guarantor and its Subsidiaries (determined on a consolidated basis in accordance with GAAP) would exceed 40% of the sum of the following (without duplication):

(a) the Debt and any other Debt Incurred by the Guarantor or any Subsidiary from the first day of such four-quarter period had been Incurred at the beginning of that period and continued to be outstanding throughout that period, and the application of the net proceeds of that Debt (including to repay or retire other Debt, including Debt under any revolving credit facility) had occurred at the beginning of that four-quarter period;

(b) the repayment or retirement of any other Debt of the Guarantor or any Subsidiary from the first day of such four-quarter period had occurred at the beginning of that period; provided that, except to the extent set forth in clause (a) or (c) of this Section 4.03, in determining the amount of Debt in this calculation, the amount of Debt under any revolving credit or similar facility will be computed based upon the average daily balance of such Debt during that four-quarter period; and

(c) in the case of any acquisition or disposition of any asset or group of assets by the Guarantor or any Subsidiary from the first day of such four-quarter period including, without limitation, by merger, or stock or asset purchase or sale, (i) the acquisition or disposition had occurred as of the first day of that period, with the appropriate adjustments to Consolidated EBITDA and Interest Expense with respect to the acquisition or disposition being included in that pro forma calculation, and (ii) the application of the net proceeds from a disposition to repay or refinance Debt, including, without limitation, Debt under any revolving credit facility, had occurred on the first day of that four-quarter period.

If an Event of Default (other than an Event of Default specified in Section 501(6) or 501(7) of the Base Indenture) occurs and is continuing, unless the principal of all the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by notice in writing to the Issuer and the Guarantor (and to the Trustee if given by Holders of Notes), may declare the principal amount of and Interest accrued and unpaid on all the Notes to be immediately due and payable.

The Notes will be issued pursuant to a Registration Statement on Form S-3 (the “Registration Statement”) filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Act”), the related prospectus dated July 29, 2022, and a prospectus supplement relating to the Notes, dated July 18, 2023 (the “Prospectus Supplement”), filed with the Commission pursuant to Rule 424(b) of the rules and regulations promulgated under the Act. This opinion is being provided at your request for incorporation by reference into the Registration Statement.

As to certain matters of fact material to this opinion, we have relied, without independent verification, upon certificates of the Operating Partnership and the Guarantor, and of certain officers of the Operating Partnership and the Guarantor.

Ladies and Gentlemen:

We have acted as United States federal income tax counsel for Piedmont Office Realty Trust, Inc., a Maryland corporation (the “Company”), and Piedmont Operating Partnership, LP, a Delaware limited partnership (the “Operating Partnership”), in connection with (i) the Registration Statement on Form S-3 dated July 29¸ 2022 (the “Registration Statement”) filed by the Company and the Operating Partnership, with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “1933 Act”), relating to the offering from time to time of (1) debt securities of the Operating Partnership, (2) the guarantee of the debt securities by the Company, (3) shares of common stock, par value $0.01 per share, of the Company, and (4) shares of preferred stock, no par value, of the Company, and (ii) a prospectus supplement dated the July 19, 2023, filed with the Commission pursuant to Rule 424(b) promulgated under the 1933 Act (the “Prospectus Supplement”), of the offer and sale of $400 million aggregate principal amount of 9.250% Senior Notes due 2028 to be sold by the Operating Partnership and guaranteed by the Company. This opinion is being rendered at the request of the Company and the Operating Partnership and relates to certain U.S. federal income tax matters.

FACTS AND ASSUMPTIONS RELIED UPON

In rendering the opinion expressed herein, we have examined such documents as we have deemed appropriate, including (but not limited to) (1) the analyses of qualifying income and assets prepared by the Company, (2) stock ownership information provided by the Company, and (3) the Registration Statement. In our examination of documents, we have assumed, with your consent, that all documents submitted to us are authentic originals, or if submitted as photocopies or facsimile copies, that they faithfully reproduce the originals thereof, that all such documents have been or will be duly executed to the extent required, that all representations and statements set forth in such documents are true and correct, and that all obligations imposed by any such documents on the parties thereto have been or will be performed or satisfied in accordance with their terms. The opinions set forth in this letter also are premised on certain additional information and representations obtained through consultation with officers of the Company and Piedmont Washington Properties, Inc. (“PWP”), including those contained in the Officer’s

Piedmont Office Realty Trust, Inc.

Piedmont Operating Partnership, LP

Page 2 of 3

Certificate delivered to us on or about the date hereof (the “Officer’s Certificate”) regarding certain facts and other matters (including among other things, representations as to the Company’s stock ownership, assets, acquisitions, revenues, and distributions) as are germane to the determination that the Company has been and will be owned and operated in such a manner that the Company has and will continue to satisfy the requirements for qualification as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). We have assumed, with your consent, that the representations set forth in the Officer’s Certificate are true, accurate, and complete as of the date hereof, and that any representation made in any of the documents referred to therein “to the knowledge and belief” of any person (or with similar qualification) is true and correct without such qualification. While we have discussed such representations with representatives of the Company, we have not conducted an independent investigation or audit of such representations.

OPINION

Based on the foregoing, and subject to the assumptions, qualifications and limitations set forth herein, we are of the opinion that:

The opinion expressed herein is based upon the current provisions of the Code, the U.S. Treasury regulations promulgated thereunder, current administrative positions of the U.S. Internal Revenue Service (the “IRS”), and existing judicial decisions, any of which could be changed at any time, possibly on a retroactive basis. Any such changes could adversely affect the opinion rendered herein and the tax consequences to the Company, the Operating Partnership, and the investors in the securities thereof. In addition, as noted above, our opinion is based solely on the documents that we have examined and the representations that have been made to us, and cannot be relied upon if any of the facts contained in such documents is, or later becomes, inaccurate or if any of the representations made to us is, or later becomes, inaccurate. We are not aware, however, of any facts or circumstances contrary to or inconsistent with the information, assumptions, and representations upon which we have relied for purposes of this opinion. Our opinion is not binding on the IRS or any court. Accordingly, no complete assurance can be given that the IRS will not challenge our opinion or that a court will not agree with the IRS.

Our opinion is limited to the tax matters specifically covered thereby. We have not been asked to address, nor have we addressed, any other tax consequences of an investment in the securities of the Company or the Operating Partnership. We have not undertaken to review the Company’s compliance with the REIT requirements on a continuing basis. Accordingly, no assurance can be given that the actual results of the Company’s operations, the sources of its income, the nature of its assets, the level of its distributions to shareholders and the diversity of its share ownership in any given taxable year will satisfy the requirements under the Code for qualification and taxation as a REIT. Finally, our opinion does not preclude the possibility that the Company may have to utilize one or more of the various “savings provisions” under the Code that would permit the Company to cure certain violations of the requirements for qualification and taxation as a REIT.

This opinion is given as of the date hereof, and we assume no obligation to advise you after the date hereof of facts or circumstances that come to our attention or changes in law that occur which could affect this opinion.

We hereby consent to the filing of this opinion as an Exhibit to the Registration Statement and to the references to our firm in the Registration Statement. In giving this consent, we do not admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the SEC thereunder, nor do we thereby admit that we are experts with respect to any part of the Registration Statement within the meaning of the term “experts” as used in the Securities Act or the rules and regulations of the SEC promulgated thereunder.
