  <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Maryland General Corporation Law, as amended (the &#147;MGCL&#148;), permits a Maryland corporation to include in its charter a provision
  limiting the liability of its directors and officers to the corporation and its stockholders for money damages except for liability resulting from (a)&nbsp;actual receipt of an improper benefit or profit in money, property or services or
  (b)&nbsp;active and deliberate dishonesty established by a final judgment as being material to the cause of action. Our charter contains a provision providing for elimination of the liability of our directors or officers to us or our stockholders
  for money damages, to the maximum extent permitted by Maryland law. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The MGCL requires a Maryland corporation (unless its charter provides
  otherwise, which our charter does not) to indemnify a director or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made a party by reason of his or her service in that capacity. The
  MGCL permits a Maryland 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 threatened to be made a party by reason of their service in those or other capacities unless it is established that (a)&nbsp;the act or omission of the director or officer was material to the matter giving rise to the
  proceeding and (i)&nbsp;was committed in bad faith or (ii)&nbsp;was the result of active and deliberate dishonesty, (b)&nbsp;the director or officer actually received an improper personal benefit in money, property or services or (c)&nbsp;in the
  case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful. However, under the MGCL, a Maryland corporation may not indemnify 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. In addition, the MGCL permits a corporation to advance
  reasonable expenses to a director or officer upon the corporation&#146;s receipt of (a)&nbsp;a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for
  indemnification and (b)&nbsp;a written undertaking by or on his or her behalf to repay the amount paid or reimbursed if it shall ultimately be determined that the standard of conduct was not met. It is the position of the Commission that
  indemnification of directors and officers for liabilities arising under the Securities Act is against public policy and is unenforceable pursuant to Section&nbsp;14 of the Securities Act. </P>
  <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our charter provides that, to the maximum extent permitted by Maryland law in effect from time to time, we must indemnify and, without
  requiring a preliminary determination of the ultimate entitlement to indemnification, must pay or reimburse reasonable expenses in advance of the final disposition of a proceeding to: (i)&nbsp;any individual who is a present or former director or
  officer of us and who is made or threatened to be made a party to, or witness in, the proceeding by reason of his or her service in such capacity; or (ii)&nbsp;any individual who, while a director or officer of us and at our request, serves or has
  served as a director, officer, member, manager, partner or trustee of another corporation, real estate investment trust, limited liability company, partnership, joint venture, trust, employee benefit plan or any other enterprise and who is made or
  threatened to be made a party to, or witness in, the proceeding by reason of his or her service in such capacity. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We also maintain
  insurance on behalf of all of our directors and executive officers against liability asserted against or incurred by them in their official capacities with us. </P>
  <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We have entered into indemnification agreements with each of our directors and executive officers (each, an &#147;Indemnitee&#148;). The
  indemnification agreements obligate us, if an Indemnitee is or is threatened to be made a party to, or witness in, any proceeding by reason of such Indemnitee&#146;s status as a present or former director or officer of us, or as a director, trustee,
  officer, partner, manager, managing member, fiduciary, employee or agent of another entity that the Indemnitee served in such capacity at our request, to indemnify such Indemnitee, and advance expenses actually and reasonably incurred by him or her,
  subject to certain exceptions and conditions. </P> <P STYLE="font-size:18pt;margin-top:0pt;margin-bottom:0pt">&nbsp;</P>

  post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this 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% change in the maximum aggregate offering price set forth in the &#147;Calculation of Registration Fee&#148; table in the effective
  Registration Statement; </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:13%; font-size:10pt; font-family:Times New Roman">(iii) To include any material information with respect to the plan of distribution not previously disclosed in

  pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:9%; font-size:10pt; font-family:Times New Roman">(2) That,
  for the purpose of determining any liability under the Securities Act, 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. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:9%; font-size:10pt; font-family:Times New Roman">(3) To remove from registration by means of a post-effective amendment any

  undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant&#146;s annual report pursuant to section 13(a) or section 15(d) of the Exchange Act (and, where applicable, each filing of an employee
  benefit plan&#146;s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement related to the securities offered therein, and the
  offering of such securities at the time shall be deemed to be the initial bona fide offering thereof. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">(h) Insofar as indemnification for
  liabilities arising under the Securities Act may be permitted to 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 Commission
  such indemnification is against public policy as expressed in the Securities Act 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 director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the
  Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the
  Securities Act and will be governed by the final adjudication of such issue. </P>

  Item 6.
  Indemnification of Directors and Officers.
  The Maryland General Corporation Law, as amended (the "MGCL"), permits a Maryland corporation to include in its charter a provision
  limiting the liability of its directors and officers to the corporation and its stockholders for money damages except for liability resulting from (a) actual receipt of an improper benefit or profit in money, property or services or
  (b) active and deliberate dishonesty established by a final judgment as being material to the cause of action. Our charter contains a provision providing for elimination of the liability of our directors or officers to us or our stockholders
  for money damages, to the maximum extent permitted by Maryland law.
  The MGCL requires a Maryland corporation (unless its charter provides
  otherwise, which our charter does not) to indemnify a director or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made a party by reason of his or her service in that capacity. The
  MGCL permits a Maryland 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 threatened to be made a party by reason of their service in those or other capacities unless it is established that (a) the act or omission of the director or officer was material to the matter giving rise to the
  proceeding and (i) was committed in bad faith or (ii) was the result of active and deliberate dishonesty, (b) the director or officer actually received an improper personal benefit in money, property or services or (c) in the
  case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful. However, under the MGCL, a Maryland corporation may not indemnify 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. In addition, the MGCL permits a corporation to advance
  reasonable expenses to a director or officer upon the corporation's receipt of (a) a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for
  indemnification and (b) a written undertaking by or on his or her behalf to repay the amount paid or reimbursed if it shall ultimately be determined that the standard of conduct was not met. It is the position of the Commission that
  indemnification of directors and officers for liabilities arising under the Securities Act is against public policy and is unenforceable pursuant to Section 14 of the Securities Act.
  Our charter provides that, to the maximum extent permitted by Maryland law in effect from time to time, we must indemnify and, without
  requiring a preliminary determination of the ultimate entitlement to indemnification, must pay or reimburse reasonable expenses in advance of the final disposition of a proceeding to: (i) any individual who is a present or former director or
  officer of us and who is made or threatened to be made a party to, or witness in, the proceeding by reason of his or her service in such capacity; or (ii) any individual who, while a director or officer of us and at our request, serves or has
  served as a director, officer, member, manager, partner or trustee of another corporation, real estate investment trust, limited liability company, partnership, joint venture, trust, employee benefit plan or any other enterprise and who is made or
  threatened to be made a party to, or witness in, the proceeding by reason of his or her service in such capacity.
  We also maintain
  insurance on behalf of all of our directors and executive officers against liability asserted against or incurred by them in their official capacities with us.
  We have entered into indemnification agreements with each of our directors and executive officers (each, an "Indemnitee"). The
  indemnification agreements obligate us, if an Indemnitee is or is threatened to be made a party to, or witness in, any proceeding by reason of such Indemnitee's status as a present or former director or officer of us, or as a director, trustee,

  Item 9.
  Undertakings.
  (a) 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;
  (ii) To reflect in the prospectus any facts or events arising after the effective date of this 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 this 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% 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
  the Registration Statement or any material change to such information in the Registration Statement;
  provided
  ,
  however
  , that
  paragraphs (a)(1)(i) and (a)(1)(ii) of this section 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 Exchange Act that are incorporated by reference in the Registration Statement.
  (2) That,
  for the purpose of determining any liability under the Securities Act, 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.
  (b) The undersigned Registrant hereby
  undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to section 13(a) or section 15(d) of the Exchange Act (and, where applicable, each filing of an employee
  benefit plan's annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement related to the securities offered therein, and the
  offering of such securities at the time shall be deemed to be the initial bona fide offering thereof.
  (h) Insofar as indemnification for
  liabilities arising under the Securities Act may be permitted to 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 Commission
  such indemnification is against public policy as expressed in the Securities Act 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 director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the
  Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the
  Securities Act and will be governed by the final adjudication of such issue.

  Pursuant to the requirements of the Securities Act, the Registrant certifies that it has reasonable grounds to believe that it meets all of
  the requirements for filing on Form
  S-8
