by the Company against all expenses incurred in connection with actions
(including, under certain circumstances, derivative actions) brought against
such director or officer by reason of his or her status as a representative of
the Company, or by reason of the fact that such director or officer serves or

serves or served as an employee or agent of any entity at the Company's request,
unless the act or failure to act on the part of the director or officer giving

binding adjudication to have constituted willful misconduct or recklessness.

Item 7.  Exemption from Registration Claimed.

Item 9.  Undertakings.

         The undersigned Registrant hereby undertakes as follows:

         (a) To file, during any period in which offers or sales are being made
pursuant to this Registration Statement, 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 this Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in 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 is registered) and any deviation from the low or high end of
the estimated maximum 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 "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 paragraphs (i) and (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 by the Registrant pursuant to Section 13 or
15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement.

         (b) 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.

                                      -5-

<PAGE>

         (c) 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.

         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 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.

         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 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 Securities Act and will be governed by the final
adjudication of such issue.

by the Company against all expenses incurred in connection with actions
(including, under certain circumstances, derivative actions) brought against
such director or officer by reason of his or her status as a representative of
the Company, or by reason of the fact that such director or officer serves or

reasonably believed to be in, or not opposed to, the best interests of the
Company. As permitted under the BCL, the Company's By-Laws provide that the
Company shall indemnify directors and officers against all expenses incurred in

director or officer by reason of the fact that he or she is or was a director or
officer of the Company, or by reason of the fact that such director or officer
serves or served as an employee or agent of any entity at the Company's request,

binding adjudication to have constituted willful misconduct or recklessness.

Item 9.  Undertakings.

         The undersigned Registrant hereby undertakes as follows:

         (a) To file, during any period in which offers or sales are being made
pursuant to this Registration Statement, 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 this Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in 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 is registered) and any deviation from the low or high end of
the estimated maximum 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 "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 paragraphs (i) and (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 by the Registrant pursuant to Section 13 or
15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement.

         (b) 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.

                                      -5-
(c) 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.

         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 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.

         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 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 Securities Act and will be governed by the final
adjudication of such issue.

                                      -6-
