ITEM 4.  DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 145 of the Delaware General Corporation Law provides, in
summary, that directors and officers of Delaware corporations are entitled,
under certain circumstances, to be indemnified against all expenses and
liabilities (including attorneys' fees) incurred by them as a result of suits
brought against them in their capacity as a director or officer, if they acted
in good faith and in a manner they reasonably believed to be in or not opposed
to the best interests of the Company, and, with respect to any criminal action
or proceeding, if they had no reasonable cause to believe their conduct was
unlawful; provided that no indemnification may be made against expenses in
respect of any claim, issue or matter as to which they shall have been adjudged
to be liable to the Company, unless and only to the extent that the court in
which such action or suit was brought shall determine upon application that,
despite the adjudication of liability but in view of all the circumstances of
the case, they are fairly and reasonably entitled to indemnity for such expenses
which the court shall deem proper. Any such indemnification may be made by the
Company only as authorized in each specific case upon a determination by the
stockholders or disinterested directors that indemnification is proper because
the indemnitee has met the applicable standard of conduct.

         Section 102(b)(7) of the Delaware General Corporate Law permits a
corporation to provide in its certificate of incorporation that a director of
the corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability: (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) in respect of certain unlawful dividend payments or stock redemptions or
purchases; or (iv) for any transaction from which the director derived an
improper personal benefit. The Company's Restated Certificate of Incorporation
provides for such limitation of liability.

         The Company's Restated Certificate of Incorporation and Restated
By-Laws provide for indemnification of its directors and officers to the fullest
extent permitted by Delaware law, as the same may be amended from time to time.

         In addition, the Company maintains liability insurance for its
directors and officers.

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 amount would not exceed
              that which was registered) and any deviation from the low or high
              end of the estimated maximum offering


                                        3




<PAGE>



              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% 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;

              Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) 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
              Registrant pursuant to Section 13 or Section 15(d) of the Exchange
              Act that are incorporated by reference in the 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 15(d) of the Exchange
Act of 1934 (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the 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.

         (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 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 of the Delaware General Corporation Law provides, in
summary, that directors and officers of Delaware corporations are entitled,
under certain circumstances, to be indemnified against all expenses and
liabilities (including attorneys' fees) incurred by them as a result of suits
brought against them in their capacity as a director or officer, if they acted
in good faith and in a manner they reasonably believed to be in or not opposed
to the best interests of the Company, and, with respect to any criminal action
or proceeding, if they had no reasonable cause to believe their conduct was
unlawful; provided that no indemnification may be made against expenses in
respect of any claim, issue or matter as to which they shall have been adjudged
to be liable to the Company, unless and only to the extent that the court in
which such action or suit was brought shall determine upon application that,
despite the adjudication of liability but in view of all the circumstances of
the case, they are fairly and reasonably entitled to indemnity for such expenses
which the court shall deem proper. Any such indemnification may be made by the
Company only as authorized in each specific case upon a determination by the
stockholders or disinterested directors that indemnification is proper because
the indemnitee has met the applicable standard of conduct.

         Section 102(b)(7) of the Delaware General Corporate Law permits a
corporation to provide in its certificate of incorporation that a director of
the corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability: (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) in respect of certain unlawful dividend payments or stock redemptions or
purchases; or (iv) for any transaction from which the director derived an
improper personal benefit. The Company's Restated Certificate of Incorporation
provides for such limitation of liability.

         The Company's Restated Certificate of Incorporation and Restated
By-Laws provide for indemnification of its directors and officers to the fullest
extent permitted by Delaware law, as the same may be amended from time to time.

         In addition, the Company maintains liability insurance for its
directors and officers.

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 amount would not exceed
              that which was registered) and any deviation from the low or high
              end of the estimated maximum offering

                                        3
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% 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;

              Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) 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
              Registrant pursuant to Section 13 or Section 15(d) of the Exchange
              Act that are incorporated by reference in the 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 15(d) of the Exchange
Act of 1934 (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the 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.

         (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 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.

                                        4
