         -----------------------------------------------

         The following documents filed by the Registrant with the Securities

         (i)      The Registrant's Annual Report on Form 10-K for the fiscal

                  31, 2001; and

         (iv)     The description of the Registrant's Common Stock contained
                  in the Registrant's Registration Statement on Form S-1,
                  filed on February 12, 2001, and any amendment or report
                  filed for the purposes of updating such description.

         All documents filed by the Registrant pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Securities Exchange Act of 1934, as amended,
after the date of this Registration Statement and prior to the filing of a
post-effective amendment which indicates that all securities offered hereby
have been sold or which deregisters all securities remaining unsold, shall
be deemed to be incorporated by reference in this Registration Statement and
to be made a part hereof from the date of filing of such documents. Any
statements contained herein or in a document incorporated herein by
reference shall be deemed to be modified or superseded for purposes of this
Registration Statement to the extent that a statement contained in a
subsequently filed document incorporated herein by reference modifies or
supersedes such document. Any statement so modified or superseded shall not
be deemed, except as so modified or superseded, to constitute a part of this
Registration Statement.

         Where any document or part thereof is incorporated by reference in
this Registration Statement, the Registrant will provide without charge to

delivered, upon written or oral request of such person, a copy of any and

Statement, excluding exhibits unless such exhibits are specifically

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

         Section 145 of the Delaware General Corporation Law provides that,
among other things, a corporation may indemnify directors and officers as
well as other employees and agents of the corporation against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
in connection with specified actions, suits or proceedings, whether civil,
criminal, administrative or


                                   - 2 -





investigative (other than action by or in the right of the corporation, a
"derivative action"), 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
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe their conduct was unlawful. A similar standard
is applicable in the case of derivative actions, except that indemnification
only extends to expenses (including attorneys' fees) incurred in connection
with the defense or settlement of such actions, and the statute requires
court approval before there can be any indemnification where the person
seeking indemnification has been found liable to the corporation. The
statute provides that it is not exclusive of other indemnification that may
be granted by a corporation's bylaws, disinterested director vote,
stockholder vote, agreement or otherwise.

         Article Sixth of the Registrant's amended and restated certificate
of incorporation and Article IV of the Registrant's amended and restated
by-laws require indemnification to the fullest extent permitted by Delaware
law. The Registrant has also obtained officers' and directors' liability
insurance which insures against liabilities that officers and directors of
the Registrant, in such capacities, may incur. The Registrant's amended and
restated certificate of incorporation requires the advancement of expenses
incurred by officers or directors in relation to any action, suit or
proceeding.

         Section 102(b)(7) of the Delaware General Corporation 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 duties as a
director, except for liability (i) for any transaction from which the
director derives an improper personal benefit, (ii) for acts or omissions
not in good faith or that involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the Delaware General
Corporation Law (certain illegal distributions) or (iv) for any breach of a
director's duty of loyalty to the corporation or its stockholders. Article
Eleven of the Registrant's amended and restated certificate of incorporation
includes such a provision.

Item 8.  Exhibits.
         --------

         See Exhibit Index on page 9 hereof.

Item 9.  Undertakings.
         ------------

         (a)      The undersigned registrant hereby undertakes:

                  (1)      To file, during any period in which offers and
         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 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;

                           (iii)    To include any material information with
                  respect to the plan of distribution previously disclosed
                  in this registration statement or any material change to
                  such information in this registration statement;

                                   - 3 -




provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
this 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
Securities Exchange Act of 1934 that are incorporated by reference in this
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 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.

         (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 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.
