promptly of the time when any subsequent amendment to the Registration Statement has become effective or any subsequent supplement to the Prospectus has been filed and of any request by the Commission for any amendment or supplement to the
Registration Statement or the Prospectus or for additional information; the Company will prepare and file with the Commission, promptly upon the Sales Managers reasonable request, any amendments or supplements to the Registration Statement or
Prospectus that, in the Sales Managers reasonable opinion based upon advice of counsel, may be necessary in connection with the sale of the Shares pursuant to this Agreement; the Company will not file any amendment or supplement to the
Registration Statement or Prospectus (other than a supplement to the Prospectus that (i) relates solely to the issuance of securities other than shares of Shares of the Company and (ii) does not materially change the information about the Company or
its business, operations, properties or financial condition disclosed in the Registration Statement or Prospectus previously thereto (an Excluded Supplement)) unless a copy thereof has been submitted to the Sales Manager a reasonable
period of time before the filing and the Sales Manager has not reasonably objected thereto; and it will notify the Sales Manager at the time of filing of any document that upon filing is deemed to be incorporated by reference in the Registration
Statement or Prospectus. The Company will cause each amendment or supplement to the Prospectus to be filed with the Commission as required pursuant to the applicable paragraph of Rule 424(b) of the Rules and Regulations or, in the case of any
document to be incorporated therein by reference, to be filed with the Commission as required pursuant to the Exchange Act, within the time period prescribed.



(c) The Company will advise the Sales Manager, promptly after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of
any stop order suspending the effectiveness of the Registration Statement, of the suspension of the qualification of the Shares for offering or sale in any jurisdiction, or of the initiation or threatening of any proceeding for any such purpose; and
it will promptly use commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal if such a stop order should be issued.



(d) Within the time during which a prospectus relating to the Shares is required to be delivered under the Act, the Company
will comply with all requirements imposed upon it by the Act and by the Rules and Regulations, as from time to time in force, so far as necessary to permit the continuance of sales of or dealings in the Shares as contemplated by the provisions
hereof and the Prospectus. If during such period any event occurs as a result of which the Prospectus, as then amended or supplemented, would include an untrue statement of a material fact or omit to state a material fact necessary to make the
statements therein, in the light of the circumstances then existing, not misleading, or if during such period it is necessary to amend or supplement the Registration Statement or Prospectus to comply with the Act, the Company will promptly notify



10



---

the Sales Manager to suspend the offering of Shares during such period and the Company will amend or supplement the
Registration Statement or Prospectus (at the expense of the Company) so as to correct such statement or omission or effect such compliance and will use its best reasonable efforts to have any amendment or supplement to the Registration Statement or
Prospectus declared effective as soon as possible, unless the Company has reasonable business reasons to defer public disclosure of the relevant information.



(e) The Company will use commercially reasonable efforts to qualify the Shares for sale under the securities laws of such jurisdictions as the Sales
Manager designates and to continue such qualifications in effect so long as required for the sale of the Shares, except that the Company shall not be required in connection therewith to qualify as a foreign corporation or to execute a general
consent to service of process in any jurisdiction or to qualify or register as a dealer in securities in any jurisdiction in which it is not so qualified or registered, or provide any undertaking or make any change in its charter or by-laws that the
Board of Trustees of the Company reasonably determines to be contrary to the best interests of the Company and its shareholders or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so
subject.



(f) The Company will furnish to the Sales Manager and
its counsel (at the expense of the Company) copies of the Registration Statement or the Prospectus during the period in which a prospectus relating to the Shares is required to be delivered under the Act, in each case as soon as available and in
such quantities as the Sales Manager may from time to time reasonably request and, in the case when the Trading Market is a national securities exchange, the Company will also furnish copies of the Prospectus to such exchange in accordance with Rule
153 of the Rules and Regulations.



(g) The Company will make
generally available to its security holders as soon as practicable, but in any event not later than 15 months after the end of the Companys current fiscal quarter, an earnings statement (which need not be audited) covering a 12-month period
that satisfies the provisions of Section 11(a) of the Act and Rule 158 of the Rules and Regulations.



(h) The Company, whether or not the transactions contemplated hereunder are consummated or this Agreement is terminated, will pay all of its expenses
incident to the performance of its obligations hereunder (including, but not limited to, any transaction fees imposed by any governmental or self-regulatory organization with respect to transactions contemplated by this Agreement and any blue sky
fees) and will pay the expenses of printing all documents relating to the offering. The Company will reimburse the Sales Manager for its reasonable out-of-pocket costs and expenses incurred in connection with entering into this Agreement, including,
without limitation, reasonable travel, reproduction, ongoing due diligence, printing and similar expenses, as well as the reasonable fees and disbursements of its legal counsel, upon presentation of appropriate invoices thereof (provided that such
total costs and expenses shall not exceed $25,000).



(i) The
Company shall use commercially reasonable efforts to list, subject to official notice of issuance, the Shares on the applicable Trading Market so long as the Companys common shares are trading on such Trading Market or the Companys
common shares are then admitted for trading on such Trading Market.



11



---

(j) The Company will apply the Net Proceeds from the sale of the Shares as set forth in the Prospectus.



(k) The Company will not, directly or indirectly, offer or
sell any common shares (other than the Shares) or securities convertible into or exchangeable for, or any rights to purchase or acquire, common shares, during the period from the date the Registration Statement is declared effective by the
Commission of this Agreement through the final Settlement Date for the sale of Shares hereunder without (i) giving the Sales Manager at least one business day prior written notice specifying the nature of the proposed sale and the date of such
proposed sale and (ii) suspending activity under this program for such period of time as may reasonably be determined by agreement of the Company and the Sales Manager; provided, however, that no such notice and suspension shall be
required in connection with the Companys issuance or sale of (i) common shares pursuant to any employee or trustee stock option or benefits plan, stock ownership plan, dividend reinvestment plan, as such plans may be amended from time to time,
(ii) common shares issuable upon conversion of securities or the exercise of warrants, options or other rights in effect or outstanding as of the date the Registration Statement is declared effective by the Commission, (iii) common shares issuable
upon exchange of units pursuant to the Partnership Agreement (iv) securities issued in connection with the acquisition of real estate in the ordinary course of the Companys business, and (v) securities issued pursuant to the Original Sales
Agreement or any other agreement with the Sales Manager. Notwithstanding the foregoing, this paragraph (k) shall not apply during periods that the Company is neither selling Shares through the Sales Manager nor has requested the Sales Manager to
sell Shares.



(l) The Company will, at any time during the term
of this Agreement, as supplemented from time to time, advise the Sales Manager promptly after it shall have received notice or obtain knowledge thereof, of any information or fact that would alter or affect any opinion, certificate, letter and other
document provided to the Sales Manager pursuant to Article IV below. The Sales Manager acknowledges it shall be deemed to have been advised of such information or facts that have been made publicly available by means of the Companys filings
under the Act or the Exchange Act. Notwithstanding the foregoing, this paragraph (l) shall not apply during periods that the Company is neither selling Shares through the Sales Manager nor has requested the Sales Manager to sell Shares.



(m) Each time that the Registration Statement or the Prospectus shall be
amended or supplemented (other than an Excluded Supplement), the Company shall (unless the Company is not then selling Shares through the Sales Manager and has not requested the Sales Manager to sell Shares) furnish or cause to be furnished to the
Sales Manager forthwith a certificate dated the date of filing with the Commission of such amendment, supplement or other document, the date of effectiveness of amendment, as the case may be, in form satisfactory to the Sales Manager to the effect
that the statements contained in the certificates referred to in Section 4.1(f) below that were last furnished to the Sales Manager are true and correct at the time of such amendment, supplement, filing, as the case may be, as though made at and as
of such time (except that such statements shall be deemed to relate to the Registration Statement or the Prospectus as amended and supplemented to such time) or, in lieu of such certificates, certificates of the same tenor as the certificates
referred to in said Section 4.1(f) below, modified as necessary to relate to the Registration Statement or the Prospectus as amended and supplemented to the time of delivery of such certificate.



12



---

(n) (i) Each time that (1) the Registration Statement shall be amended by the filing of a post-effective
amendment thereto or (2) the Company files a Form 10-K; and (ii) at such other times, as may be reasonably requested by the Sales Manager, when the Prospectus is supplemented and/or any document or report is filed with the Commission and is deemed
to be incorporated into the Registration Statement or the Prospectus; the Company (unless the Company is neither selling Shares through the Sales Manager nor has requested the Sales Manager to sell Shares) shall furnish or cause to be furnished
forthwith to the Sales Manager and to the Sales Managers counsel a written opinion of Akin, Gump, Strauss, Hauer & Feld, L.L.P.,counsel to the Company (Company Counsel), or other counsel satisfactory to the Sales
Manager, dated the date of filing with the Commission of such amendment, supplement or other document and the date of effectiveness of such amendment, as the case may be, in form and substance satisfactory to the Sales Manager, of the same tenor as
the opinion referred to in Section 4.1(d) below, but modified as necessary to relate to the Registration Statement and the Prospectus as amended and supplemented to the time of delivery of such opinion.



(o) Each time that the Registration Statement or the Prospectus shall be
amended or supplemented (other than an Excluded Supplement) to include additional financial information, the Company shall (unless (1) otherwise agreed to by the Sales Manager or (2) the Company is not then selling Shares through the Sales Manager
and has not requested the Sales Manager to sell Shares) cause PricewaterhouseCoopers LLP, or other independent public accountants then retained by the Company, forthwith to furnish to the Sales Manager a letter, dated the date of effectiveness of
such amendment, or the date of filing of such supplement or other document with the Commission, as the case may be, in form satisfactory to the Sales Manager, of the same tenor as the letter referred to in Section 4.1(e) below but modified to relate
to the Registration Statement or the Prospectus, as amended and supplemented to the date of such letter.

ARTICLE V.



INDEMNIFICATION AND CONTRIBUTION



5.1 (a) The Company agrees to indemnify and hold harmless the Sales Manager and each person, if any, who controls the Sales Manager within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, as
follows:



(i) against any and all loss,
liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the representations in this Agreement or contained in the Registration Statement (or any
amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or arising
out of any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary
in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;



(ii) against any and all expense whatsoever, (including, subject to Section 5.1(c) below, the reasonable fees and disbursements of counsel
chosen by the Sales Manager), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any
such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) above;



provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Sales Manager expressly for use in the Registration Statement (or any
amendment thereto) or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto).



15



---

(b) The Sales Manager agrees to indemnify and hold harmless the Company and its directors or trustees and
each officer and employee of the Company, and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any and all loss, liability, claim, damage and expense described in the
indemnity contained in Section 5.1(a) above, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendments thereto) or any preliminary
prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Sales Manager expressly for use in the Registration Statement (or any
amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto). The total liability of the Sales Manager under this Section 5.1 (b) shall not exceed the total actual sales price of Shares sold by the
Sales Manager that is the subject of the dispute.



(c) Any
indemnified party that proposes to assert the right to be indemnified under this Article V will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying
party or parties under this Article V, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party will not relieve the indemnifying party from
any liability that it might have to any indemnified party to the extent it is not materially prejudiced as a result thereof. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the
indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with
any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the
defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and
other charges of such counsel will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified party has reasonably concluded
(based on the written advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (3) a conflict or potential conflict exists
(based on the written advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the
indemnified party) or (4) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees,
disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such



16



---

jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges
will be reimbursed by the indemnifying party promptly as they are incurred. An indemnifying party will not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld).



(d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in the foregoing paragraphs of this Article V is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or the Sales Manager, the Company and the
Sales Manager will contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or
proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than the Sales Manager, such as persons who control the Company within the meaning of the Act, officers of the Company and directors or
trustees of the Company, who also may be liable for contribution) to which the Company and the Sales Manager may be subject in such proportion as shall be appropriate to reflect the relative fault of the Company, on the one hand, and the Sales
Manager, on the other, with respect to the statements or omission which resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering.
Such relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Sales Manager,
the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Sales Manager agree that it would not be just and equitable if contributions pursuant
to this Section 5.1(d) were to be determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result
of the loss, claim, liability, expense or damage, or action in respect thereof, referred to above in this Section 5.1(d) shall be deemed to include, for the purpose of this Section 5.1(d), subject to the limitations on such amounts in Section
5.1(a), (b), and (c) above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the foregoing provisions of this Section 5.1(d), the Sales
Manager shall not be required to contribute any amount in excess of the amount by which the total actual sales price at which Shares sold under this Agreement by the Sales Manager since the date hereof exceeds the amount of any damages that the
Sales Manager has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) will be
entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 5.1(d), any person who controls a party to this Agreement within the meaning of the Act will have the same rights to
contribution as that party, and each officer and director or trustee of the Company will have the same rights to contribution as the Company, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt
of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 5.1(d), will notify any such party or parties from whom contribution may be sought, but the omission so to notify
will not relieve that party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 5.1(d). No party will be liable for contribution with respect to any action or claim settled without its
written consent (which consent will not be unreasonably withheld).



17



---

(e) The indemnity and contribution provided by this Article V shall not relieve the Company and the Sales
Manager from any liability the Company and the Sales Manager may otherwise have (including, without limitation, any liability the Sales Manager may have for a breach of its obligations under Article II above).



ARTICLE VI.

herein becomes untrue or inaccurate.
