ITEM 4.  DESCRIPTION OF SECURITIES.

     Not Applicable.

ITEM 5.  INTERESTS OF EXPERTS AND COUNSEL.

     None.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The Company's officers and directors are and will be indemnified under
Maryland and Delaware law, the Charter and Bylaws of the Company and the
Partnership Agreement of the Operating Partnership against certain liabilities.
The Company's Charter requires the Company to indemnify its directors and
officers to the fullest extent permitted from time to time under Maryland law.

     The Company's Bylaws require it to indemnify (a) any present or former
director or officer who has been successful, on the merits or otherwise, in the
defense of a proceeding to which he was made a party by reason of his service in
that capacity, against reasonable expenses incurred by him in connection with
the proceeding and (b) any present or former director or officer against any
claim or liability unless it is established that (i) his act or omission was
committed in bad faith or was the result of active or deliberate dishonesty,
(ii) he actually received an improper personal benefit in money, property or
services or (iii) in the case of a criminal proceeding, he had reasonable cause
to believe that his act or omission was unlawful.

     In addition, the Company's Bylaws require the Company to pay or reimburse,
in advance of final disposition of a proceeding, reasonable expenses incurred by
a present or former director or officer made a party to a proceeding by reason
of his service as a director or officer provided that the Company shall have
received (i) 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 Company as authorized by the Bylaws and (ii) a written understanding by or
on his behalf to repay the amount paid or reimbursed by the Company if it shall
ultimately be determined that the standard of conduct was not met. The Bylaws
also (i) permit the Company to provide indemnification and advance expenses to a
present or former director or officer who served a predecessor of the Company in
such capacity, and to any employee or agent of the Company or a predecessor of
the Company, (ii) provide that any indemnification or payment or reimbursement
of the expenses permitted or reimbursement of expenses under Section 2-418 of
the MGCL for directors of Maryland corporations and (iii) permit the Company to
provide such other and further indemnification or payment or reimbursement of
expenses as may be permitted by Section 2-418 of the MGCL for directors of
Maryland corporations.

     Under Maryland law, a corporation formed in Maryland is permitted to limit,
by provision in its charter, the liability of directors and officers so that no
director or officer of the Company shall be liable to the Company or to any
stockholder for money damages except to the extent that (i) the director or
officer actually received an improper benefit in money, property or services,
for the amount of the benefit or profit in money, property or services actually
received,


                                       3


or (ii) a judgment or other final adjudication adverse to the director or
officer is entered in a proceeding based on a finding in a proceeding that the
director's of officer's action was the result of active and deliberate
dishonesty and was material to the cause of action adjudicated in the
proceeding. The Charter has incorporated the provisions of such law limiting the
liability of directors and officers.

     The Partnership Agreement also provides for indemnification of the Company
and its officers and directors to the same extent indemnification is provided to
officers and directors of the Company in its organizational documents, and
limits the liability of the Company and its officers and directors to the
Operating Partnership and its partners to the same extent liability of officers
and directors of the Company to the Company and its stockholders is limited
under their organizational documents.

ITEM 9.  UNDERTAKINGS

     The undersigned registrants hereby undertake:

     (a)(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, represents a fundamental change in the
               information set forth in the 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) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
Section 13 or 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 the 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) 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 15(d) of the Securities Exchange Act of 1934 that is incorporated by
reference in this registration statement shall deemed to be a new registration
statement relating to the securities offered herein, and the offering of such
securities at the time shall be deemed to be the initial bona fide offering
thereof.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the provisions referred to in Item 6 of this
registration statement, 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 Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by 


                                       5


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 securities being registered, the registrant will, unless in
the opinion of 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 Act and will
be governed by the final adjudication of such issue.


                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the Company
