      Not applicable.

Item 6. Indemnification of Directors and Officers.

      The Delaware General Corporation Law and the Registrant's Second Amended
and Restated Certificate of Incorporation and Amended and Restated By-laws
provide for indemnification of the Registrant's directors and officers for
liabilities and expenses that they may incur in such capacities. In general,
directors and officers are indemnified with respect to actions taken in good
faith in a manner reasonably believed to be in, or not opposed to, the best
interests of the Registrant, and with respect to any criminal action or
proceeding, actions that the indemnitee had no reasonable cause to believe were
unlawful. Reference is made to the Registrant's Second Amended and Restated
Certificate of Incorporation and Amended and Restated By-laws filed as Exhibits
3.2 and 3.4, respectively, to the Registrant's Registration Statement on Form
S-1 (File No. 333-81233) and incorporated herein by reference.

      The underwriting agreement, dated August 20, 1999, by and between the
Registrant and the underwriters listed therein provides that the underwriters
are obligated, under certain circumstances, to indemnify directors, officers and
controlling persons of the Registrant against certain liabilities, including
liabilities under the Securities Act of 1933. Reference is made to the form of
underwriting agreement filed as Exhibit 1.1 to the Registrant's Registration
Statement on Form S-1 (File No. 333-81233) and incorporated herein by reference.

      The Registrant has in effect a directors' and officers' liability
insurance policy.

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 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


                                      -5-
<PAGE>

            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;

                (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; and

            (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 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 herein 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 Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such
issue.

Item 6. Indemnification of Directors and Officers.

      The Delaware General Corporation Law and the Registrant's Second Amended
and Restated Certificate of Incorporation and Amended and Restated By-laws
provide for indemnification of the Registrant's directors and officers for
liabilities and expenses that they may incur in such capacities. In general,
directors and officers are indemnified with respect to actions taken in good
faith in a manner reasonably believed to be in, or not opposed to, the best
interests of the Registrant, and with respect to any criminal action or
proceeding, actions that the indemnitee had no reasonable cause to believe were
unlawful. Reference is made to the Registrant's Second Amended and Restated
Certificate of Incorporation and Amended and Restated By-laws filed as Exhibits
3.2 and 3.4, respectively, to the Registrant's Registration Statement on Form
S-1 (File No. 333-81233) and incorporated herein by reference.

      The underwriting agreement, dated August 20, 1999, by and between the
Registrant and the underwriters listed therein provides that the underwriters
are obligated, under certain circumstances, to indemnify directors, officers and
controlling persons of the Registrant against certain liabilities, including
liabilities under the Securities Act of 1933. Reference is made to the form of
underwriting agreement filed as Exhibit 1.1 to the Registrant's Registration
Statement on Form S-1 (File No. 333-81233) and incorporated herein by reference.

      The Registrant has in effect a directors' and officers' liability
insurance policy.

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 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

                                      -5-
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;

                (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; and

            (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 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 herein 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 Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such
issue.

                                      -6-
