Indemnification of Directors and
      Officers
.
Section
      2-405.2 of the Maryland General Corporation Law 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 monetary damages
      except:  (1) to the extent it is proven that the director or officer
      actually received an improper benefit or profit, for the amount of the improper
      benefit or profit; or (2) to the extent a final judgment or adjudication against
      the director or officer is based on a determination that the director
'
s or officer
'
s
      act or failure to act was the result of active and deliberate dishonesty and
      was
      material to the cause of action against the director or officer.  The
      Registrant
'
s
      charter contains such a provision, thereby limiting the liability of its
      directors and officers to the maximum extent permitted by Maryland
      law.
2
Section
      2-418 of the Maryland General Corporation Law permits a Maryland corporation
      to
      indemnify a director or officer who is made a party to any proceeding by reason
      of service in that capacity against judgments, penalties, fines, settlements
      and
      reasonable expenses actually incurred unless it is proven that: (1) the act
      or
      omission of the director or officer was material to the matter giving rise
      to
      the proceeding and was committed in bad faith or with active and deliberate
      dishonesty; (2) the director or officer actually received an improper personal
      benefit; or (3) in the case of a criminal proceeding, the director or officer
      had reason to believe that his conduct was unlawful.  The Maryland
      General Corporation Law provides that where a director or officer is a defendant
      in a proceeding by or in the right of the corporation, the director or officer
      may not be indemnified if he or she is found liable to the
      corporation.  The Maryland General Corporation Law also provides that
      a director or officer may not be indemnified in respect of any proceeding
      alleging improper personal benefit in which he or she was found liable on the
      grounds that personal benefit was improperly received.  A director or
      officer found liable in a proceeding by or in the right of the corporation
      or in
      a proceeding alleging improper personal benefit may petition a court to
      nevertheless order indemnification for expenses if the court determines that
      the
      director or officer is fairly and reasonably entitled to indemnification in
      view
      of all the relevant circumstances.
Section
      2-418 of the Maryland General Corporation Law provides that unless limited
      by
      the charter of a Maryland corporation, a director or officer who is successful
      on the merits or otherwise in defense of any proceeding must be indemnified
      against reasonable expenses.  Section 2-418 also provides that a
      Maryland corporation may advance reasonable expenses to a director or officer
      upon the corporation's receipt of (a) a written affirmation by the director
      or
      officer of his or her good faith belief that he or she has met the standard
      of
      conduct necessary for indemnification by the corporation and (b) a written
      undertaking by the director or officer or on his or her behalf to repay the
      amount paid or reimbursed by the corporation if it is ultimately determined
      that
      the standard of conduct was not met.
The
      Registrant's charter provides for indemnification of directors and officers
      to
      the maximum extent permitted by the Maryland General Corporation
      Law.
Under

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, 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 a 20% change in the maximum aggregate offering
      price set forth in the "Calculation of Registration Fee" table in the effective
      registration statement; and
3
(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 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 the
                Registrant's annual report pursuant to Section 13(a) or Section 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 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 of expenses
                incurred or paid by a director, officer or controlling person 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.
