Item 4. Description of Securities.

      Not Applicable.


                                      2


Item 5. Interests of Named Experts and Counsel.

      None.

Item 6. Indemnification of Directors and Officers.

      The Maryland General Corporation Law, as amended from time to time (the
"MGCL"), permits a Maryland corporation to include in its charter a provision
limiting the liability of its directors and officers to the corporation and
its stockholders for money damages except for liability resulting from (a)
actual receipt of an improper benefit or profit in money, property or services
or (b) active and deliberate dishonesty established by a final judgment as
being material to the cause of action. The charter of the Company (the
"Charter") contains such a provision which eliminates such liability to the
maximum extent permitted by Maryland law.

      Our Charter authorizes us, to the maximum extent permitted by Maryland
law, to obligate ourselves to indemnify and to pay or reimburse reasonable
expenses in advance of final disposition of a proceeding to (a) any present or
former director or officer or (b) any individual who, while a director of the
Company and at the request of the Company serves or has served another
corporation, real estate investment trust, partnership, joint venture, trust,
employee benefit plan or any other enterprise as a director, officer, partner
or trustee of such corporation, real estate investment trust, partnership,
joint venture, trust, employee benefit plan or other enterprise and who is
made a party to the proceeding by reason of his or her service in that
capacity. Our bylaws obligate us, to the maximum extent permitted by Maryland
law, to indemnify and to pay or reimburse reasonable expenses in advance of
final disposition of a proceeding to (a) any present or former director or
officer who is made a party to the proceeding by reason of his/her service in
that capacity or (b) any individual who, while a director of the Company and
at the request of the Company, serves or has served another corporation, real
estate investment trust, partnership, joint venture, trust, employee benefit
plan or any other enterprise as a director, officer, partner or trustee of
such corporation, real estate investment trust, partnership, joint venture,
trust, employee benefit plan or other enterprise and who is made a party to
the proceeding by reason of his service in that capacity. Our Charter and
bylaws also permit us to indemnify and advance expenses to any person who
served a predecessor of the Company in any of the capacities described above
and to any employee or agent of the Company or a predecessor of the Company.

      The MGCL requires a corporation (unless its charter provides otherwise,
which our Charter does not) to indemnify a director or officer who is
successful (on the merits or otherwise) in the defense of (a) any proceeding
to which he is made a party by reason of his service in that capacity and (b)
any issue, claim or matter in such a proceeding. The MGCL permits a
corporation to indemnify its present and former directors and officers, among
others, against judgments, penalties, fines, settlements and reasonable
expenses actually incurred by them in connection with any proceeding to which
they may be made a party by reason of their service in those or other
capacities unless it is established that (a) the act or omission of the
director or officer was material to the matter giving rise to the proceeding
and (i) was committed in bad faith or (ii) was the result of active and
deliberate dishonesty, (b) the director or officer actually received an
improper personal benefit in money, property or services or (c) in the case of
any criminal proceeding, the director or officer had reasonable cause to
believe that the act or omission was unlawful. However, under the MGCL, a
Maryland corporation may not indemnify for an adverse judgment in a suit by or
in the right of the corporation or for a judgment of liability on the basis
that personal benefit was improperly received, unless in either case a court
orders indemnification and then only for expenses. In addition, the MGCL
permits a corporation to advance reasonable expenses, upon the corporation's
receipt of (a) 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 corporation and (b) a written


                                      3


statement by or on his behalf to repay the amount paid or reimbursed by the
corporation if it shall ultimately be determined that the standard of conduct
was not met.

      We have entered into indemnification agreements with each of our
executive officers and directors. The indemnification agreements require,
among other matters, that we indemnify our executive officers and directors to
the fullest extent permitted by law and advance to the executive officers and
directors all related expenses, subject to reimbursement if it is subsequently
determined that indemnification is not permitted. Under these agreements, we
must also indemnify and advance all expenses incurred by executive officers
and directors seeking to enforce their rights under the indemnification
agreements and may cover executive officers and directors under the Company's
directors' and officers' liability insurance. Although indemnification
agreements offer substantially the same scope of coverage afforded by the
bylaws, they provide greater assurance to directors and executive officers
that indemnification will be available, because, as contracts, they cannot be
modified unilaterally in the future by the Board of Directors or the
stockholders to eliminate the rights they provide.

Item 9. Undertakings

      The undersigned registrant hereby undertakes:

      (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;

            (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, represent 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 reports filed with or furnished to the Commission
by the registrant pursuant to Section 13 or 15(d) of the Exchange Act that are
incorporated by reference in the Registration Statement.

      (2) That, for the purpose of determining any liability under the
Securities Act, 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 that 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, each filing of the registrant's annual report pursuant to Section 13(a)
or 15(d) of the Exchange Act that is incorporated by


                                      5


reference in this Registration Statement shall be 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 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 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 the securities being registered, the registrant
will, unless in the opinion of its 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.
