ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.


        The Registrant's Articles of Incorporation, as amended, provide that the
Registrant shall indemnify its directors and officers whether serving the
Registrant or, at the Registrant's request, another entity, to the fullest
extent required or permitted by the general laws of the State of Maryland now or
hereafter in force, including the advance of expenses under the procedures
provided by such laws. The Registrant's Articles of Incorporation also provide
that the Registrant shall indemnify its other agents or employees, whether
serving the Registrant, or at its request, another entity, to such extent as is
authorized by the Board of Directors or the By-laws of the Registrant and as
permitted by law.

        The Maryland General Corporation Law provides that a corporation may
indemnify any director made a party to a proceeding by reason of service in that
capacity unless it is established that: (1) the act or omission of the director
was material to the matter giving rise to the proceeding and (a) was committed
in bad faith or (b) was the result of active and deliberate dishonesty, or (2)
the director actually received an improper personal benefit in money, property
or services, or (3) in the case of any criminal proceeding, the director had
reasonable cause to believe that the act or omission was unlawful. To the extent
that a director has been successful in defense of any proceeding, the Maryland
General Corporation Law provides that he or she shall be indemnified against
reasonable expenses incurred in connection therewith. A Maryland corporation may
indemnify its officers to the same extent as its directors and to such further
extent as is consistent with law.

ITEM 7.           EXEMPTION FROM REGISTRATION CLAIMED.

                  Not applicable.

ITEM 9. UNDERTAKINGS.


        The undersigned Registrant hereby undertakes:

        (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 Securities Act of 1933 (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.

        Paragraphs (1)(i) and (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 section 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 that remain unsold at the
termination of the offering.

        The undersigned Registrant hereby undertakes 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 section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement 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.

        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 foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the

<PAGE>   5


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.

        Pursuant to the requirements of the Securities Act, the Registrant

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        The Registrant's Articles of Incorporation, as amended, provide that the
Registrant shall indemnify its directors and officers whether serving the
Registrant or, at the Registrant's request, another entity, to the fullest
extent required or permitted by the general laws of the State of Maryland now or
hereafter in force, including the advance of expenses under the procedures
provided by such laws. The Registrant's Articles of Incorporation also provide
that the Registrant shall indemnify its other agents or employees, whether
serving the Registrant, or at its request, another entity, to such extent as is
authorized by the Board of Directors or the By-laws of the Registrant and as
permitted by law.

        The Maryland General Corporation Law provides that a corporation may
indemnify any director made a party to a proceeding by reason of service in that
capacity unless it is established that: (1) the act or omission of the director
was material to the matter giving rise to the proceeding and (a) was committed
in bad faith or (b) was the result of active and deliberate dishonesty, or (2)
the director actually received an improper personal benefit in money, property
or services, or (3) in the case of any criminal proceeding, the director had
reasonable cause to believe that the act or omission was unlawful. To the extent
that a director has been successful in defense of any proceeding, the Maryland
General Corporation Law provides that he or she shall be indemnified against
reasonable expenses incurred in connection therewith. A Maryland corporation may
indemnify its officers to the same extent as its directors and to such further
extent as is consistent with law.

ITEM 7.           EXEMPTION FROM REGISTRATION CLAIMED.

ITEM 9. UNDERTAKINGS.

        The undersigned Registrant hereby undertakes:

        (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 Securities Act of 1933 (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.

        Paragraphs (1)(i) and (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 section 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 that remain unsold at the
termination of the offering.

        The undersigned Registrant hereby undertakes 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 section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement 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.

        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 foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the
5

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.
