ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS

                  Section 145(a) of the General Corporation Law of the State of
Delaware ("DGCL") provides that a Delaware corporation may indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of the
corporation), by reason of the fact that the person is or was a director,
officer, employee or agent of the corporation or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation or enterprise, against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by the person in connection with such action, suit or proceeding if the person



                                       I-1

<PAGE>



acted in good faith and in a manner the person reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful.

                  Section 145(b) of the DGCL provides that a Delaware
corporation may indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action or suit by or in
the right of the corporation to procure a judgment in its favor by reason of the
fact that the person acted in any of the capacities set forth above, against
expenses (including attorneys' fees) actually and reasonably incurred by the
person in connection with the defense or settlement of such action or suit if
the person acted under similar standards, except that no indemnification may be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the corporation unless and only to the extent that
the court in which such action or suit was brought shall determine that despite
the adjudication of liability, such person is fairly and reasonably entitled to
be indemnified for such expenses which the court shall deem proper.

                  Section 145 of the DGCL further provides that to the extent a
director or officer of a corporation has been successful on the merits or
otherwise in the defense of any action, suit or proceeding referred to in
subsections (a) and (b) or in the defense of any claim, issue or matter therein,
such person shall be indemnified against expenses actually and reasonably
incurred by such person in connection therewith; that indemnification provided
for by Section 145 shall not be deemed exclusive of any other rights to which
the indemnified party may be entitled; and that the corporation may purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation or
enterprise, against any liability asserted against such person and incurred by
such person in any such capacity or arising out of such person's status as such,
whether or not the corporation would have the power to indemnify such person
against such liabilities under such Section 145.

                  Section 102(b)(7) of the DGCL provides that a certificate of
incorporation may contain a provision eliminating or limiting the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director provided that such provision
shall not eliminate or limit the liability of a director: (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders; (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law; (iii) under Section 174 of the DGCL; or (iv) for any
transaction from which the director derived an improper personal benefit.

                  Our Amended and Restated Certificate of Incorporation and
By-Laws provide that we may indemnify all persons who we are entitled to
indemnify under the DGCL to the fullest extent permitted thereunder.
Furthermore, our Amended and Restated Certificate of Incorporation provides
that, to the extent permitted under Section 102(b)(7) of the DGCL, none



                                       I-2

<PAGE>



of our directors will be personally liable to H Power or its stockholders for
monetary damages for breach of fiduciary duty as a director. We have entered or
will enter into indemnification agreements with each of our directors and
executive officers, which will indemnify these persons to the fullest extent
permitted under the DGCL.

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,
                  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 the volume of securities offered (if the total
                  dollar value of securities offered would not exceed that
                  which was registered) and



                                       I-3

<PAGE>



                  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 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 the
                  registration statement or any material change to such
                  information 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.

(h)      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
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.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS

                  Section 145(a) of the General Corporation Law of the State of
Delaware ("DGCL") provides that a Delaware corporation may indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of the
corporation), by reason of the fact that the person is or was a director,
officer, employee or agent of the corporation or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation or enterprise, against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by the person in connection with such action, suit or proceeding if the person

                                       I-1
acted in good faith and in a manner the person reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful.

                  Section 145(b) of the DGCL provides that a Delaware
corporation may indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action or suit by or in
the right of the corporation to procure a judgment in its favor by reason of the
fact that the person acted in any of the capacities set forth above, against
expenses (including attorneys' fees) actually and reasonably incurred by the
person in connection with the defense or settlement of such action or suit if
the person acted under similar standards, except that no indemnification may be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the corporation unless and only to the extent that
the court in which such action or suit was brought shall determine that despite
the adjudication of liability, such person is fairly and reasonably entitled to
be indemnified for such expenses which the court shall deem proper.

                  Section 145 of the DGCL further provides that to the extent a
director or officer of a corporation has been successful on the merits or
otherwise in the defense of any action, suit or proceeding referred to in
subsections (a) and (b) or in the defense of any claim, issue or matter therein,
such person shall be indemnified against expenses actually and reasonably
incurred by such person in connection therewith; that indemnification provided
for by Section 145 shall not be deemed exclusive of any other rights to which
the indemnified party may be entitled; and that the corporation may purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation or
enterprise, against any liability asserted against such person and incurred by
such person in any such capacity or arising out of such person's status as such,
whether or not the corporation would have the power to indemnify such person
against such liabilities under such Section 145.

                  Section 102(b)(7) of the DGCL provides that a certificate of
incorporation may contain a provision eliminating or limiting the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director provided that such provision
shall not eliminate or limit the liability of a director: (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders; (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law; (iii) under Section 174 of the DGCL; or (iv) for any

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,
                  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 the volume of securities offered (if the total
                  dollar value of securities offered would not exceed that
                  which was registered) and

                                       I-3
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 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 the
                  registration statement or any material change to such
                  information 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.

(h)      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
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.

Registration Statement to be signed on its behalf by the undersigned, thereunto
