The MGCL permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made, or are threatened to be made, a party by reason of their service in those capacities. However, a Maryland corporation is not permitted to provide this type of indemnification if the following is established:</font></p>

Item 4.  Description of Securities.
Not applicable.
Item 5.  Interests of Named Experts and Counsel.
Not applicable.
Item 6.  Indemnification of Directors and Officers.
The Company's declaration of trust includes provisions limiting the liability of its present and former trustees and officers for money damages and obligating the Company to indemnify its present and former trustees and officers against any claim or liability to which they may become subject by reason of their status or actions as present or former trustees or officers of the Company to the maximum extent permitted by Maryland law.
The Company's declaration of trust also obligates the Company to pay or reimburse the people described above for reasonable expenses in advance of final disposition of a proceeding.
The laws relating to Maryland real estate investment trusts, or the Maryland REIT Law, permit a real estate investment trust formed under Maryland law to indemnify and advance expenses to its trustees, officers, employees and agents to the same extent permitted by the Maryland General Corporation Law, or the MGCL, for directors, officers, employees and agents of Maryland corporations. The MGCL permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made, or are threatened to be made, a party by reason of their service in those capacities. However, a Maryland corporation is not permitted to provide this type of indemnification if the following is established:
·
the act or omission of the director or officer was material to the matter giving rise to the proceeding and (1) was committed in bad faith or (2) was the result of active and deliberate dishonesty;
·
the director or officer actually received an improper personal benefit in money, property or services; or
·
in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful.
Under the MGCL, a Maryland corporation may not indemnify a director or officer for an adverse judgment in a suit by or in the right of the corporation or for a judgment of liability on the basis that personal benefit was improperly received, unless in either case a court orders indemnification and then only for expenses. The MGCL permits a corporation to advance reasonable expenses to a director or officer upon the corporation's receipt of the following:
·
a written affirmation by the director or officer of his good faith belief that he has met the standard of conduct necessary for indemnification by the corporation; and
·
a written undertaking by the director or officer or on his behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that this standard of conduct was not met.
The Company has also entered into indemnification agreements with its trustees and its officers providing for procedures for indemnification by the Company to the fullest extent permitted by law and advancements by the Company of certain expenses and costs relating to claims, suits or proceedings arising from their service to the Company.
2
The Commission has expressed the opinion that indemnification of trustees, officers or persons otherwise controlling a company for liabilities arising under the Securities Act is against public policy and is therefore unenforceable.
Reference is made to the Company's declaration of trust filed as Exhibit 3.1 to its Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2012. Reference is also made to the Company's indemnification agreements with its trustees and officers, a form of which is filed as Exhibit 10.3 to the Company's Current Report on Form 8-K filed with the Commission on May 23, 2012.

Item 9.  Undertakings.
The undersigned registrant hereby undertakes:
(1)
To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)
To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
(ii)
To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;
(iii)
To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in the registration statement;
provided, however,
that paragraphs (i) and (ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.
(2)
That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof.
(3)
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(4)
That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof.
(5)
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to trustees, directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a trustee, director, officer or controlling person of the registrant in the successful defense of any action, suit
