<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">(a)&nbsp;The undersigned Registrant hereby undertakes:



<P align="left" style="margin-left:3%; font-size: 10pt">(1)&nbsp;To file, during any period in which offers or sales are being made, a post-effective
amendment to this registration statement:



<P align="left" style="margin-left:6%; font-size: 10pt">(i)&nbsp;To include any prospectus required by Section&nbsp;10(a)(3) of the Securities Act of 1933;



<P align="left" style="margin-left:6%; font-size: 10pt">(ii)&nbsp;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,

<P align="left" style="margin-left:6%; font-size: 10pt">individually or in the aggregate, represent a fundamental change in the information set
forth in the registration statement. Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of securities offered
would not exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus filed with
the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
price represent no more than 20% change in the maximum aggregate offering price set forth
in the &#147;Calculation of Registration Fee&#148; table in the effective registration statement.



<P align="left" style="margin-left:6%; font-size: 10pt">(iii)&nbsp;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.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><U>provided, however</U>, that paragraphs (a)(1)(i) and (a) (1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information required to be
included in a post-effective amendment by those paragraphs is contained in periodic reports filed
with or furnished to the Commission by the Registrant pursuant to Section&nbsp;13 or Section 15(d) of
the Securities Exchange Act of 1934 that are incorporated by reference in the registration
statement.



<P align="left" style="margin-left:3%; font-size: 10pt">(2)&nbsp;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 that time shall be
deemed to be the initial bona fide offering thereof.



<P align="left" style="margin-left:3%; font-size: 10pt">(3)&nbsp;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.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">(b)&nbsp;The undersigned Registrant hereby undertakes that, for purposes of determining any liability
under the Securities Act of 1933, each filing of our annual report pursuant to Section 13(a) or
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee
benefit plan&#146;s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) 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.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">(c)&nbsp;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
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 Act and is,
therefore, unenforceable. In the event that a claim for indemnification against such liabilities
(other than the payment by the registrant of the expenses incurred or paid by a director, officer,
or controlling person of the Registrant of 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 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.

Item 6. Indemnification of Directors and Officers.
Section 2-418 of the Maryland General Corporation Law provides for the indemnification of
directors and officers of a corporation incorporated under Maryland law under certain
circumstances. A person who was or is a director or officer of the corporation may be indemnified
by the corporation for judgments, penalties, fines, settlements and reasonable expenses (including
attorneys' fees) actually incurred by the director or officer in connection with any threatened,
pending or completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, to which such director or officer was or is made a party by reason of service in
that capacity unless it is established that (1) 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; (2) the director actually received an
II-1
improper personal benefit in money, property or services; or (3) in the case of any criminal
proceeding, the director or officer had reasonable cause to believe that the act or omission was
unlawful. If a proceeding is brought by or on behalf of the corporation, no indemnification will
be made in connection with such proceeding if the director or officer was adjudged to be liable to
the corporation.
Article Eighth of the Articles of Incorporation of the Registrant provides that the Registrant
shall indemnify its directors and officers to the full extent permitted by Maryland Law now or
hereafter in force, including the advance of related expenses, upon a determination by the Board of
Directors or independent legal counsel made in accordance with applicable statutory standards, and
that the Registrant, upon authorization by the Board of Directors, may indemnify other employees or
agents to the same extent. Article Eighth also provides that to the fullest extent permitted by
Maryland law, no director of officer of the Registrant shall be personally liable to the Registrant
or its stockholders for money damages and that no amendment of the Registrant's charter or repeal
of any of its provisions shall limit or eliminate the benefits provided to directors and officers
under such provision with respect to any act or omission which occurred prior to such amendment or
repeal.
Article VIII of the By-Laws of the Registrant provides that the Registrant shall indemnify its
directors and officers unless (1) the act or omission of the director was committed in bad faith or
was the result of active and deliberate dishonesty, (2) the director actually received an improper
benefit in money, property or services or, (3) in the case of a criminal proceeding, the director
had reasonable cause to believe that the act or omission was unlawful.
The Registrant also maintains directors' and officers' liability insurance.
Certain of the Registrant's employee benefit plans provide for indemnification of directors
and officers against certain claims arising from administration of such plans.

Item 9. Undertakings.
(a) 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 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,
II-2
individually or in the aggregate, represent a fundamental change in the information set
forth in the registration statement. Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of securities offered
would not exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus filed with
the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
price represent no more than 20% change in the maximum aggregate offering price set forth
in the "Calculation of Registration Fee" table in the effective 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
registration statement is on Form S-3, Form S-8 or Form F-3, and the information required to be
included in a post-effective amendment by those paragraphs is contained in periodic reports filed
with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 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 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) The undersigned Registrant hereby undertakes that, for purposes of determining any liability
under the Securities Act of 1933, each filing of our annual report pursuant to Section 13(a) or
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) 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.
(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
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 Act and is,
therefore, unenforceable. In the event that a claim for indemnification against such liabilities
(other than the payment by the registrant of the expenses incurred or paid by a director, officer,
or controlling person of the Registrant of 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 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.
II-3
