ITEM 4.  DESCRIPTION OF SECURITIES.

     Not Applicable.

ITEM 5.  INTERESTS OF EXPERTS AND COUNSEL.

     None.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

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

     Under Maryland law, a corporation formed in Maryland is permitted to
limit, by provision in its articles of incorporation, 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, 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 Articles of
Incorporation have incorporated the provisions of such law limiting the
liability of directors and officers.

     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.

     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 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
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in The City of New York and State of New York, on the 18th day of
August, 1999.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

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

     Under Maryland law, a corporation formed in Maryland is permitted to
limit, by provision in its articles of incorporation, 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, 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 Articles of
Incorporation have incorporated the provisions of such law limiting the
liability of directors and officers.

     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.

     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 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
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in The City of New York and State of New York, on the 18th day of
August, 1999.
