IMPORTANT NOTICE

The Corporation will furnish to any stockholder, on request and without charge, a full statement of the information required by Section 2-211(b) of the Corporations and Associations Article of the Annotated Code of Maryland with respect to the designations and any preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends and other distributions, qualifications, and terms and conditions of redemption of the stock of each class which the Corporation has authority to issue and, if the Corporation is authorized to issue any preferred or special class in series, (i) the differences in the relative rights and preferences between the shares of each series to the extent set, and (ii) the authority of the Board of Directors to set such rights and preferences of subsequent series. The foregoing summary does not purport to be complete and is subject to and qualified in its entirety by reference to the Charter, a copy of which will be sent without charge to each stockholder who so requests. Such request must be made to the Secretary of the Corporation at its principal office.

The shares represented by this certificate are subject to restrictions on Beneficial Ownership and Constructive Ownership and Transfer for the purpose, among others, of the Corporation’s maintenance of its qualification as a real estate investment trust under the Internal Revenue Code of 1986, as amended (the “Code”). Subject to certain further restrictions and except as expressly provided in the Charter, (i) no Person may Beneficially Own or Constructively Own shares of Common Stock in excess of 9.8 percent (in value or number of shares, whichever is more restrictive) of the outstanding shares of Common Stock unless such Person is an Excepted Holder (in which case the Excepted Holder Limit shall be applicable); (ii) no Person may Beneficially Own or Constructively Own shares of Capital Stock in excess of 9.8 percent (in value or number of shares, whichever is more restrictive) of the total outstanding shares of Capital Stock, unless such Person is an Excepted Holder (in which case the Excepted Holder Limit shall be applicable); (iii) no Person may Beneficially Own or Constructively Own Capital Stock that would result in the Corporation being “closely held” under Section 856(h) of the Code or otherwise cause the Corporation to fail to qualify as a REIT; and (iv) any Transfer of shares of Capital Stock that, if effective would result in the Capital Stock being beneficially owned by less than 100 persons (as determined under the principles of Section 856(a)(5) of the Code) shall be void ab initio, and the intended transferee shall acquire no rights in such shares of the Capital Stock. Any Person who Beneficially Owns or Constructively Owns or attempts to Beneficially Own or Constructively Own shares of Capital Stock which causes or will cause a Person to Beneficially Own or Constructively Own shares of Capital Stock in excess or in violation of the above limitations must immediately notify the Corporation. If any of the restrictions on transfer or ownership as set forth in (i) through (iii) above are violated, the shares of Capital Stock in excess or in violation of the above limitations will be automatically transferred to a Trustee of a Trust for the benefit of one or more Charitable Beneficiaries. In addition, the Corporation may redeem shares upon the terms and conditions specified by the Board of Directors in its sole discretion if the Board of Directors determines that ownership or a Transfer or other event may violate the restrictions described above. Furthermore, upon the occurrence of certain events, attempted Transfers in violation of the restrictions described in (i) through (iii) above may be void ab initio.

Subject to certain further restrictions and except as expressly provided in the Charter, including the Articles Supplementary establishing the Series A Preferred Stock, no Person may Beneficially Own or Constructively Own shares of Series A Preferred Stock in excess of 9.8 percent (in value or number of shares, whichever is more restrictive) of the outstanding shares of Series A Preferred Stock unless such Person is a Series A Excepted Holder (in which case the Series A Excepted Holder Limit shall be applicable). Any Person who Beneficially Owns or Constructively Owns or attempts to Beneficially Own or Constructively Own shares of Series A Preferred Stock which causes or will cause a Person to Beneficially Own or Constructively Own shares of Series A Preferred Stock in excess or in violation of the above limitation must immediately notify the Corporation or, in the case of such a proposed or attempted transaction, give at least 15 days prior written notice. If the restriction on transfer or ownership as set forth above is violated, the shares of Series A Preferred Stock in excess or in violation of the above limitation will be automatically transferred to a Series A Trustee of a Series A Trust for the benefit of one or more Series A Charitable Beneficiaries. In addition, the Corporation may redeem shares upon the terms and conditions specified by the Board of Directors in its sole discretion if the Board of Directors determines that ownership or a Transfer or other event may violate the restriction described above. Furthermore, upon the occurrence of certain events, attempted Transfers in violation of the restriction described above may be void ab initio. Unless otherwise defined herein, all capitalized terms in this legend have the meanings defined in the Charter, as the same may be amended from time to time, a copy of which, including the restrictions on transfer and ownership, will be furnished to each holder of Capital Stock on request and without charge. Requests for such a copy may be directed to the Secretary of the Corporation at its principal office.
