                                EXPLANATORY NOTE

         This Form S-8 Registration Statement relates to 1,500,000 shares of our

         The documents containing information specified by Part I of this

specified in Rule 428(b)(1) promulgated by the Securities and Exchange
Commission under the Securities Act of 1933, as amended. These documents do not
need to be filed with the Commission but constitute (along with the documents
incorporated by reference into this Registration Statement pursuant to Item 3 of
Part II of this Registration Statement) a prospectus that meets the requirements
of Section 10(a) of the Securities Act of 1933.


                                     PART II

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

         We file annual, quarterly and special reports, proxy statements and
other information with the Commission. You may read and copy any document we
file at the Commission's public reference rooms in Washington, DC, New York, NY
and Chicago, IL. Please call the Commission at 1-800-SEC-0330 for further

         The Commission allows us to "incorporate by reference" information into
this Registration Statement, which means that we can disclose important

part of this Registration Statement, and later information that we file with the
Commission will automatically update this Registration Statement. We incorporate
by reference the following documents and any future filings made with the

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 that a
corporation may indemnify directors and officers as well as other employees and
individuals against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement in connection with specified actions, suits and
proceedings, whether civil, criminal, administrative, or investigative (other
than an 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
action, 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 certificate of
incorporation, bylaws, disinterested director vote, stockholder vote, agreement,
or otherwise.

         Our bylaws and our certificates of incorporation require us to
indemnify to the fullest extent authorized by the Delaware law any person made
or threatened to be made a party to an action, suit or proceeding, whether
criminal, civil, administrative or investigative, by reason of the fact that he
or she is or was a director or officer of the Company, or is or was serving at
the request of the Company as a director, officer, employee or agent of another
corporation or of a partnership, joint venture, trust or other enterprise. As
permitted by Section 102(b)(7) of the Delaware law, our certificate of
incorporation eliminates the liability of a director to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liabilities arising (a) from any breach of the director's duty of
loyalty to the corporation or its stockholders; (b) from acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law; (c) under section 174 of the Delaware law; or (d) from any transaction from
which the director derived an improper personal benefit.

         In addition, we maintain director and officer liability insurance as
permitted by Delaware law on behalf of directors, officers, employees or agents,
which may cover liabilities under the Securities Act of 1933.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

         Not Applicable.

- ----------

*        Filed herewith


         The Registrant hereby undertakes to submit the plan and any amendment
thereto to the Internal Revenue Service ("IRS") in a timely manner and to make
all changes required by the IRS in order to qualify the plan under Section 401
of the Internal Revenue Code of 1986, as amended.

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;

                           (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;


                                       3
   5

                  Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
         not apply if 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 Registrant hereby undertakes that, for purposes of determining
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 that is incorporated by reference in this registration
statement shall be deemed to be a new registration statement relating to the
securities offering herein, 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 provisions described in Item 6 of this
registration statement, 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 section, 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.
