ITEM 6.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.

all liability expenses incurred by or imposed upon them as a result of actions,
suits or proceedings brought against them as such directors and officers, or as
directors or officers of any other organization at the request of the Company,

not opposed to the best interests of the Company, and with respect to any
criminal action or proceeding, have no reasonable cause to believe their conduct
was unlawful, except that no indemnification shall be made against expenses in

ITEM 9.   UNDERTAKINGS.

         (a)      The undersigned Company 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, as amended (the "Securities
         Act");


                                       3
<PAGE>

                           (ii) To reflect in the prospectus any facts or events
         arising after the effective date of this 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 this 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 and 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 percent 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 this
         Registration Statement or any material change to such information in
         this Registration Statement;

PROVIDED, HOWEVER, that the undertakings set forth in paragraphs (a)(1)(i) and
(a)(1)(ii) above 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 Company pursuant to Section 13 or 15(d) of
the Exchange Act that are incorporated by reference in this 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) The undersigned Company hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the Company's
annual report pursuant to Section 13(a) or 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 this
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 may be permitted to directors, officers and controlling persons
of the Company pursuant to the foregoing provisions, or otherwise, the Company
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 payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company 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
Company 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 Securities Act and will be governed by the final adjudication
of such issue.

directors or officers of any other organization at the request of the Company,

ITEM 9.   UNDERTAKINGS.

         (a)      The undersigned Company 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, as amended (the "Securities
         Act");

                                       3
(ii) To reflect in the prospectus any facts or events
         arising after the effective date of this 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 this 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 and 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 percent 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 this
         Registration Statement or any material change to such information in
         this Registration Statement;

PROVIDED, HOWEVER, that the undertakings set forth in paragraphs (a)(1)(i) and
(a)(1)(ii) above 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 Company pursuant to Section 13 or 15(d) of
the Exchange Act that are incorporated by reference in this 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) The undersigned Company hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the Company's
annual report pursuant to Section 13(a) or 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 this
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 may be permitted to directors, officers and controlling persons
of the Company pursuant to the foregoing provisions, or otherwise, the Company
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 payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company 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
Company 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 Securities Act and will be governed by the final adjudication
of such issue.

                                       4
