                                IMPORTANT NOTICE
 
     The Trust will furnish to any shareholder, on request and without charge, a
full statement of the information required by Section 8-203(d) 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
shares of each class of beneficial interest which the Trust has authority to
issue and, if the Trust 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 they have been set, and (ii) the authority
of the Board of Trustees to set the relative 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 Declaration of
Trust of the Trust, a copy of which will be sent without charge to each
shareholder who so requests. Such request must be made to the Secretary of the
Trust at its principal office.
 
     The shares represented by this certificate are subject to restrictions on
Beneficial and Constructive Ownership and Transfer for the purpose of the
Trust's maintenance of its status as a real estate investment trust (a "REIT")
under the Internal Revenue Code of 1986, as amended (the "Code"). Subject to
certain further restrictions and except as expressly provided in the Trust's
Declaration of Trust, as may be amended from time to time, (i) no Person may
Beneficially or Constructively Own Common Shares of the Trust in excess of 9.8
percent (in value or number of shares) of the outstanding Common Shares of the
Trust unless such Person is an Excepted Holder (in which case the Excepted
Holder Limit shall be applicable); (ii) no Person may Beneficially or
Constructively Own Equity Shares of the Trust in excess of 9.8 percent of the
value of the total outstanding Equity Shares of the Trust, unless such Person is
an Excepted Holder (in which case the Excepted Holder Limit shall be
applicable); (iii) no Person may Beneficially or Constructively Own Equity
Shares that would result in the Trust being "closely held" under Section 856(h)
of the Code or otherwise cause the Trust to fail to qualify as a REIT; and (iv)
no Person may Transfer Equity Shares if such Transfer would result in Equity
Shares of the Trust being owned by fewer than 100 Persons. Any Person who
Beneficially or Constructively Owns or attempts to Beneficially or
Constructively Own Equity Shares which cause or will cause a Person to
Beneficially or Constructively Own Equity Shares in excess or in violation of
the above limitations must immediately notify the Trust. If any of the
restrictions on transfer or ownership are violated, the Equity Shares
represented hereby will be automatically transferred to a Trustee of a Trust for
the benefit of one or more Charitable Beneficiaries. In addition, 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 Trust's Declaration of Trust, 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
Equity Shares of the Trust on request and without charge. Such request must be
made to the Secretary of the Trust at its principal office.
