Ladies and Gentlemen:

Healthcare Trust of America Holdings, LP, a Delaware limited partnership (the “Operating Partnership”), and Healthcare Trust of America, Inc., a Maryland corporation (the “Company” and, together with the Operating Partnership, the “Transaction Entities”), each confirms its agreement (this “Agreement”) with ▇▇▇▇▇ Fargo Securities, LLC, ▇.▇. ▇▇▇▇▇▇ Securities LLC and U.S. Bancorp Investments, Inc. and each of the other underwriters named in Exhibit A hereto (collectively, the “Underwriters”, which term shall also include any underwriter substituted as hereinafter provided in Section 9 hereof), for whom ▇▇▇▇▇ Fargo Securities, LLC, ▇.▇. ▇▇▇▇▇▇ Securities LLC and U.S. Bancorp Investments, Inc. are acting as representatives (in such capacity, the “Representatives”) with respect to the issue and sale by the Operating Partnership and the purchase by the Underwriters, acting severally and not jointly, of the respective principal amounts set forth in Exhibit A hereto of (i) $400,000,000 aggregate principal amount of 2.950% Senior Notes due 2022 (the “2022 Notes”) and (ii) $500,000,000 aggregate principal amount of 3.750% Senior Notes due 2027 (the “2027 Notes” and, together with the 2022 Notes, the “Securities”). The Securities are to be issued by the Operating Partnership pursuant to separate indentures, each dated on or about June 8, 2017, among the Operating

Partnership, U.S. Bank National Association, as trustee (the “Trustee”), and the Company, as guarantor (collectively, the “Indentures”). This agreement by and among the Company, the Operating Partnership and the Underwriters shall be referred to as this “Agreement.”

The Transaction Entities understand that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

HTA Acquisition Sub, LLC, a Delaware limited liability company and wholly-owned subsidiary of the Operating Partnership (the “Duke Buyer”), has entered into agreements of purchase and sale (the “Duke Purchase Agreements”) with Duke Realty Limited Partnership, an Indiana limited partnership (“Duke Realty LP”), and Duke Construction Limited Partnership, an Indiana limited partnership (“Duke Construction LP” and, collectively with Duke Realty LP, the “Duke Sellers”). The Duke Purchase Agreements provide that (i) the Duke Sellers are engaged in the business of providing construction, development, leasing and property management services to their clients in the healthcare industry, including hospital systems and medical offices (the “Duke Platform”), and (ii) the applicable Duke Sellers are the owners or lessees of the land and the owners of buildings and other improvements situated on such land, constituting the properties listed opposite their names on Schedule A to the Duke Purchase Agreements (individually, a “Duke Property” and, collectively, the “Duke Properties”). The Duke Properties, together with the Asset-Related Property (as defined in the Purchase Agreements) with respect to each Duke Property, shall be referred to herein, collectively, as the “Duke Assets.” Pursuant to the terms of the Duke Purchase Agreements, the Duke Buyer has agreed to acquire the Duke Platform and the Duke Assets (the “Duke Acquisition”). In addition, the Operating Partnership has agreed to guarantee the obligations of the Duke Buyer under the Duke Purchase Agreements (the “PSA Guarantees”). The Transaction Entities expect to fund a portion of the purchase price of the Duke Acquisition with a portion of the net proceeds from the sale of the Securities pursuant to this Agreement. Contemporaneously with entering into the Duke Purchase Agreements, the Operating Partnership also obtained a written commitment (the “Bridge Loan Commitment”) from ▇▇▇▇▇ Fargo Bank, National Association and ▇▇▇▇▇ Fargo Securities, LLC to provide a bridge loan facility for purposes of financing a portion of the Duke Acquisition and to pay related fees, commissions and expenses. In addition, contemporaneously with entering into the Duke Purchase Agreements, Duke Realty LP, as lender, also agreed to enter into a Loan Agreement with the Duke Buyer, as borrower, and a related Promissory Note, among other documents, for purposes of providing financing for the Duke Acquisition and to pay related fees, commissions and expenses (the “Duke Seller Financing Documents”). The Duke Buyer’s obligations under the Duke Seller Financing Documents will be guaranteed by the Operating Partnership (the “Duke Seller Financing Guarantee”). The Duke Purchase Agreements (including the PSA Guarantees), the Bridge Loan Commitment and the Duke Seller Financing Documents (including the Duke Seller Financing Guarantee) are collectively referred to herein as the “Duke Transaction Agreements.”

The Transaction Entities have prepared and previously delivered to you a preliminary prospectus supplement dated June 1, 2017 relating to the Securities and a related prospectus dated February 27, 2015 (the “Base Prospectus”). Such preliminary prospectus supplement and Base Prospectus, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act of 1933, as amended

(the “Securities Act”), are hereinafter called, collectively, the “Preliminary Prospectus Supplement.” The Transaction Entities have prepared and delivered to each Underwriter, in a form approved by the Representatives and attached as Exhibit B hereto, copies of a pricing term sheet, dated June 1, 2017 (the “Pricing Term Sheet”), describing the terms of the Securities. Promptly after the execution and delivery of this Agreement, the Transaction Entities will prepare a final prospectus supplement to be dated June 1, 2017 (the “Prospectus Supplement”) and will file the Prospectus Supplement and the Base Prospectus with the Securities and Exchange Commission (the “Commission”), all in accordance with the provisions of Rule 430B and Rule 424(b), and the Company has previously advised you of all information (financial and other) that will be set forth therein. The Prospectus Supplement and the Base Prospectus, in the form first furnished to the Underwriters for use in connection with the offering of the Securities (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, and with respect to any date or time referred to in this Agreement, the most recent prospectus supplement (whether the Preliminary Prospectus Supplement or the Prospectus Supplement, or any amendment to either such document) are herein called, collectively, the “Prospectus.”

The Securities will be fully and unconditionally guaranteed as to the payment of principal and interest by the Company (the “Guarantees”) in accordance with the terms of the Securities and the Indentures.

Securities issued in book entry form will be issued to Cede & Co. as nominee of The Depository Trust Company (“DTC”).

All references in this Agreement to financial statements and schedules and other information which is “disclosed,” “contained,” “included,” “set forth” or “stated” (or other references of like import) in the Prospectus shall be deemed to include all such financial statements and schedules and other information that are incorporated by reference in the Prospectus and all references in this Agreement to amendments or supplements to the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which is incorporated by reference in the Prospectus.

SECTION 1. Representations and Warranties of the Transaction Entities. Each of the Transaction Entities, jointly and severally, represents and warrants to, and agrees with, the several Underwriters as of the date hereof, as of the Applicable Time referred to below and as of the Closing Date referred to in Section 2(b) hereof, as follows:

Commission by the Company, or (ii) is a “road show that is a written communication” within the meaning of Rule 433(d)(8)(i), whether or not required to be filed with the Commission, or (iii) is exempt from filing with the Commission pursuant to Rule 433(d)(5)(i) because it contains a description of the Securities or of the offering that does not reflect the final terms, in each case in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g).

Each document incorporated by reference in the Registration Statement or the Prospectus heretofore filed, when it was filed (or, if any amendment with respect to any such document was filed, when such amendment was filed), conformed in all material respects with the requirements of the Exchange Act, and any further documents so filed and incorporated after the date of this Agreement will, when they are filed, conform in all material respects with the requirements of the Exchange Act.

the form of the Registration Statement or any post-effective amendment thereto, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction or of the loss or suspension of any exemption from any such qualification, or of the initiation or threatening of any proceedings for any of such purposes, or of any examination pursuant to Section 8(e) of the Securities Act concerning the Registration Statement and (v) if any of the Transaction Entities becomes the subject of a proceeding under Section 8A of the Securities Act in connection with the offering of the Securities. The Transaction Entities will make every reasonable effort to prevent the issuance of any stop order and the suspension or loss of any qualification of the Securities for offering or sale and any loss or suspension of any exemption from any such qualification, and if any such stop order is issued, or any such suspension or loss occurs, to use commercially reasonable efforts to seek to obtain the lifting thereof at the earliest reasonably practicable moment.

SECTION 6. Indemnification and Contribution.

(a) The Transaction Entities, jointly and severally, will indemnify and hold harmless each Underwriter, its partners, members, directors, officers, employees, affiliates and agents and each person, if any, who controls such Underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages, liabilities or expenses, joint or several, to which any of them may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation or at common law or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement (or any amendment thereto), Issuer Free Writing Prospectus, Preliminary Prospectus Supplement, the Disclosure Package, the Prospectus, in each case as amended or supplemented, or any Supplemental Offering Materials, or arise out of or are based upon the

omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (other than with respect to the Registration Statement and any amendments thereto, in the light of the circumstances under which they were made) not misleading, and will reimburse each indemnified party for any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such loss, claim, damage, liability, action or expense as such expenses are incurred; provided, however, that no Transaction Entity will be liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with the Underwriter Content.

(b) Each Underwriter severally and not jointly will indemnify and hold harmless each Transaction Entity, its directors and officers and each person, if any, who controls the such Transaction Entity within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages, liabilities or expenses to which any of them may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation or at common law or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Preliminary Prospectus Supplement, the Disclosure Package, the Prospectus, in each case as amended or supplemented, or any Supplemental Offering Materials, or arise out of or are based upon the omission or the alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to any Transaction Entity by such Underwriter through the Representatives specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by each indemnified party in connection with investigating or defending any such loss, claim, damage, liability, or expense as such expenses are incurred, it being understood and agreed that the only such information furnished on behalf of each of the Underwriters consists of the third paragraph, the third and fourth sentence of the sixth paragraph, the first sentence of the seventh paragraph, and the second sentence of the eighth paragraph appearing under the caption “Underwriting (Conflicts of Interest)” in the Prospectus (the “Underwriter Content”).

(c) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under Section 6(a) or 6(b) above, notify, in writing, the indemnifying party of the commencement thereof; but the omission to so notify the indemnifying party will not relieve it from any liability that it may have to any indemnified party under Section 6(a) or 6(b) above unless and to the extent such failure results in the forfeiture by the indemnifying party of material substantive rights and defenses. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party to represent the indemnified party and any others entitled to indemnification pursuant to Section 6 hereof, and after notice from the indemnifying party to such indemnified party of its election so to

assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. Notwithstanding anything contained herein to the contrary, if indemnity may be sought pursuant to Section 6(a) hereof in respect to such action or proceeding, then, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one separate firm (in addition to any local counsel) for the indemnified parties. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action, (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party, and (iii) does not include any undertaking or obligation to act or to refrain from acting by the indemnified party. Notwithstanding the foregoing, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonable fees and expenses of counsel (as specified in Section 6 hereof), such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by this Section 6(c) effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party (as specified in this Section 6(c)) all amounts reasonably owed in accordance with such request prior to the date of such settlement.

(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under Section 6(a) or 6(b) above for any reason, then each indemnifying party (with respect to the Transaction Entities, jointly and severally) shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to in Section 6(a) or 6(b) above (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) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above 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 which resulted in such losses, claims, damages, liabilities or expenses 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 proportion as the total net proceeds from the offering (before deducting expenses) received by the Transaction Entities bear to the total discounts and commissions received by the Underwriters under this Agreement. The relative fault 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 Transaction Entities or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to in the first sentence of this Section 6(d) shall be

deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this Section 6(d). Notwithstanding the provisions of this Section 6(d), no Underwriter (except as may be provided in any agreement among Underwriters relating to the offering of the Securities) shall be required to contribute any amount in excess of the discount or commission applicable to the Securities purchased by such Underwriter hereunder. 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 in this Section 6(d) to contribute are several in proportion to their respective obligations and not joint. The Transaction Entities and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or another method of allocation that does not take account of the equitable considerations referred to above.

(e) The obligations of the Transaction Entities under this Section shall be in addition to any liability that the Transaction Entities may otherwise have and shall extend, upon the same terms and conditions, to each affiliate, partner, member, director, officer, employee or agent of any Underwriter and any person, if any, who controls any Underwriter within the meaning of the Securities Act or the Exchange Act; and the obligations of the Underwriters under this Section shall be in addition to any liability that the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of any Transaction Entity, to each officer and to each person, if any, who controls any Transaction Entity within the meaning of the Securities Act or the Exchange Act.

SECTION 7. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates signed by any officer of the Transaction Entities or any of the Subsidiaries (whether signed on behalf of such officer, the Transaction Entities or such subsidiary) and delivered to the Representatives or counsel to the Underwriters, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any officer, director, employee, partner, member or agent of any Underwriter or any person controlling any Underwriter, or by or on behalf of the Transaction Entities, any officer, director or employee of the Transaction Entities or any person controlling the Transaction Entities, and shall survive delivery of and payment for the Securities.

SECTION 8. Termination of Agreement. The Representatives may terminate this Agreement only as to such Underwriter by written notice to the Company and the other Underwriters, as hereinafter specified at any time (i) if there has been, since the time of execution of this Agreement or since the date as of which information is given in the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Transaction Entities and the Subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in the Securities has been

suspended or materially limited by the Commission or the NYSE, or if trading generally on the NYSE has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or in Europe, or (iv) if a banking moratorium has been declared by either Federal or New York authorities.

SECTION 9. Default by One or More of the Underwriters.

(a) If one or more of the Underwriters shall fail at the Closing Date to purchase the aggregate principal amount of Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 36 hours thereafter, to make arrangements satisfactory to the Company for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 36-hour period, then:

(i) if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of Securities, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount of such Defaulted Securities in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters; or

(ii) if the number of Defaulted Securities exceeds 10% of the aggregate principal amount of Securities, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or any Transaction Entity.

No action taken pursuant to this Section 9 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, the Representatives shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 9.
