The shares represented by this certificate are subject to restrictions on Beneficial and Constructive Ownership and Transfer for the purpose of the Corporation’s maintenance of its status 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 Corporation’s Charter, (i) no Person may Beneficially or Constructively Own shares of the Corporation’s Series B Preferred Stock in excess of the Series B Ownership Limit unless such Person is a Series B Excepted Holder (in which case the Series B Excepted Holder Limit shall be applicable); (ii) no Person may Beneficially or Constructively Own shares of Series B Preferred Stock of the Corporation in excess of the Aggregate Stock Ownership Limit, unless such Person is a Series B Excepted Holder or an Excepted Holder (in which case the Series B Excepted Holder Limit or Excepted Holder Limit shall be applicable); (iii) no Person may Beneficially or Constructively Own Series B Preferred Stock that could 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) no Person may Transfer shares of Series B Preferred Stock if such Transfer would result in the Capital Stock of the Corporation being owned by fewer than 100 Persons. Any Person who Beneficially or Constructively Owns or attempts to Beneficially or Constructively Own shares of Series B Preferred Stock which causes or may cause a Person to Beneficially or Constructively Own shares of Series B Preferred Stock in excess or in violation of the above limitations 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 any of the restrictions on transfer or ownership set forth in (i) through (iii) above are violated, the shares of Series B Preferred Stock represented hereby will be automatically transferred to a Trustee of a Trust for the benefit of one or more Charitable Beneficiaries. In addition, the Corporation may take other actions, including redeeming shares upon the terms and conditions specified by the Board of Directors in its sole and absolute 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 above may be void ab initio. All capitalized terms in this legend have the meanings defined in the Charter of the Corporation, 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 Series B Preferred Stock of the Corporation on request and without charge. Requests for such a copy may be directed to the Secretary of the Corporation at its Principal Office.
