Item 6.  Indemnification of Directors and Officers.
         -----------------------------------------

         Our Amended and Restated Certificate of Incorporation limits, to the
maximum extent permitted under Delaware law, the personal liability of directors
and officers for monetary damages for breach of their fiduciary duties as
directors and officers, except in certain circumstances involving certain
wrongful acts, such as a breach of the director's duty of loyalty or acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law.

         Section 145 of the General Corporation Law of the State of Delaware
permits us to indemnify officers, directors or employees against expenses,
including attorneys' fees, judgments, fines and amounts paid in settlement in
connection with legal proceedings if the officer, director or employee acted in
good faith and in a manner reasonably believed to be in or not opposed to our
best interests and, with respect to any criminal act or proceeding, if he or she
had no reasonable cause to believe his or her conduct was unlawful.
Indemnification is not permitted as to any matter as to which the person is
adjudged to be liable unless, and only to the extent that, the court in which
such action or suit was brought upon application determines that, despite the
adjudication of liability, but in view of all the circumstances of the case, the
person is fairly and reasonably entitled to indemnity for such expenses as the
court deems proper. Individuals who successfully defend such an action are
entitled to indemnification against expenses reasonably incurred in connection
with the action.

         Our Amended and Restated By-Laws require us to indemnify directors and
officers against, to the fullest extent permitted by law, liabilities which they
may incur under the circumstances described in the preceding paragraph.

         We plan to maintain standard policies of insurance under which coverage
is provided (1) to our directors and officers against loss arising from claims
made by reason of breach of duty or other wrongful act and (2) to us with
respect to payments which may be made by us to such officers and directors
pursuant to the above indemnification provisions or otherwise as a matter of
law.

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;

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

                                      II-3

<PAGE>

                  any deviation from the low or high end of the estimated
                  maximum offering range may be reflected in the form of the
                  prospectus filed with the SEC pursuant to Rule 424(b) if, in
                  the aggregate, the changes in volume and price represent no
                  more than a 20 percent change in the maximum aggregate
                  offering price set forth in the "Calculation of Registration
                  Fee" table in the effective registration statement; and

                  (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 (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 SEC
by the Registrant pursuant to Section 13 or Section 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 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 Section 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 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 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 SEC 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.

Item 6.  Indemnification of Directors and Officers.
         -----------------------------------------

         Our Amended and Restated Certificate of Incorporation limits, to the
maximum extent permitted under Delaware law, the personal liability of directors
and officers for monetary damages for breach of their fiduciary duties as
directors and officers, except in certain circumstances involving certain
wrongful acts, such as a breach of the director's duty of loyalty or acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law.

         Section 145 of the General Corporation Law of the State of Delaware
permits us to indemnify officers, directors or employees against expenses,
including attorneys' fees, judgments, fines and amounts paid in settlement in
connection with legal proceedings if the officer, director or employee acted in
good faith and in a manner reasonably believed to be in or not opposed to our
best interests and, with respect to any criminal act or proceeding, if he or she
had no reasonable cause to believe his or her conduct was unlawful.
Indemnification is not permitted as to any matter as to which the person is
adjudged to be liable unless, and only to the extent that, the court in which
such action or suit was brought upon application determines that, despite the
adjudication of liability, but in view of all the circumstances of the case, the
person is fairly and reasonably entitled to indemnity for such expenses as the
court deems proper. Individuals who successfully defend such an action are
entitled to indemnification against expenses reasonably incurred in connection
with the action.

         Our Amended and Restated By-Laws require us to indemnify directors and
officers against, to the fullest extent permitted by law, liabilities which they
may incur under the circumstances described in the preceding paragraph.

         We plan to maintain standard policies of insurance under which coverage
is provided (1) to our directors and officers against loss arising from claims
made by reason of breach of duty or other wrongful act and (2) to us with
respect to payments which may be made by us to such officers and directors
pursuant to the above indemnification provisions or otherwise as a matter of
law.

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;

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

                                      II-3
any deviation from the low or high end of the estimated
                  maximum offering range may be reflected in the form of the
                  prospectus filed with the SEC pursuant to Rule 424(b) if, in
                  the aggregate, the changes in volume and price represent no
                  more than a 20 percent change in the maximum aggregate
                  offering price set forth in the "Calculation of Registration
                  Fee" table in the effective registration statement; and

                  (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 (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 SEC
by the Registrant pursuant to Section 13 or Section 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 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 Section 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 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 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 SEC 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.
