                                     PART II
               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.           Incorporation of Certain Documents by Reference.
------

          We incorporate by reference the following documents:

          (1)  Our Annual Report on Form 10-K for the year ended December 31,
2000 and all other reports filed by us pursuant to Section 13(a) or 15(d)
of the Securities Exchange Act of 1934 (the "Exchange Act") after December
31, 2000; and

          (2)  The description of our Common Stock contained in the Form 8-A
filed by us on June 22, 2000.

          If we file any documents with the SEC pursuant to Sections 13(a),
13(c), 14, and 15(d) of the Exchange Act after the date hereof and prior to the
filing of a post-effective amendment which indicates that all securities offered
have been sold or which deregisters all securities then remaining unsold, then
those documents shall be deemed to be incorporated by reference in this
registration statement and to be a part thereof from the date of filing such
documents. We refer to those documents which are subsequently filed, and the
documents listed above, as "Incorporated Documents."

          To the extent information contained in this registration statement or
any Incorporated Document differs from information contained in an earlier-filed
Incorporated Document, rely on the different information in this registration
statement or the later-filed Incorporated Document.

Item 5.           Interest of Named Experts and Counsel
------

          The validity of the shares of common stock offered hereby will be
passed on for us by Seyfarth Shaw, Chicago, Illinois. David S. Stone, a partner
in Seyfarth Shaw, is our Secretary and the beneficial owner of 633,599 shares of
our common stock. In addition, certain attorneys and a former attorney of
Seyfarth Shaw, beneficially owned an aggregate of 25,500 shares of our common
stock.

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

          Our Amended and Restated Certificate of Incorporation in effect as of
the date hereof (the "Certificate") provides that, except to the extent
prohibited by the Delaware General Corporation Law, as amended (the "DGCL"), our
directors shall not be personally liable to us or our stockholders for monetary
damages for any breach of fiduciary duty as directors. Under the DGCL, our
directors have a fiduciary duty to us which is not eliminated by this provision
of the Certificate and, in appropriate circumstances, equitable remedies such as
injunctive or other forms of non-monetary relief will remain available. In
addition, each director will continue to be subject to liability under the DGCL
for breach of the director's duty of loyalty to us, for acts or omissions which
are found by a court of competent jurisdiction to be not in good faith or
<PAGE>

involving intentional misconduct, for knowing violations of law, for actions
leading to improper personal benefit to the director, and for payment of
dividends or approval of stock repurchases or redemptions that are prohibited by
the DGCL. This provision also does not affect the directors' responsibilities
under any other laws, such as the Federal securities laws. We have obtained, and
may continue to obtain, liability insurance for our officers and directors.

          Section 145 of the DGCL empowers a corporation to indemnify its
directors and officers and to purchase insurance with respect to liability
arising out of their capacity or status as directors and officers, provided that
this provision shall not eliminate or limit the liability of a director: (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) arising under
Section 174 of the DGCL, or (iv) for any transaction from which the director
derived an improper personal benefit. The DGCL provides further that the
indemnification permitted thereunder shall not be deemed exclusive of any other
rights to which the directors and officers may be entitled under the
corporation's bylaws, any agreement, a vote of stockholders or otherwise. The
Certificate eliminates the personal liability of directors to the fullest extent
permitted by Section 102(b)(7) of the DGCL and provides that we may fully
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding (whether
civil, criminal, administrative or investigative) by reason of the fact that
such person is or was a director or officer of this corporation, or is or was
serving at our request as a director or officer of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise,
against expenses (including attorney's fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding.

Item 8.           Exhibits
------

          Reference is made to the Exhibit Index.

Item 9.           Undertakings
------

          We hereby undertake:

          (1)  To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement 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, 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.
<PAGE>

          (4)  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 (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.

          (5)  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.

intentional misconduct or a knowing violation of law, (iii) arising under
Section 174 of the DGCL, or (iv) for any transaction from which the director
derived an improper personal benefit. The DGCL provides further that the
indemnification permitted thereunder shall not be deemed exclusive of any other
rights to which the directors and officers may be entitled under the
corporation's bylaws, any agreement, a vote of stockholders or otherwise. The
Certificate eliminates the personal liability of directors to the fullest extent
permitted by Section 102(b)(7) of the DGCL and provides that we may fully
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding (whether
civil, criminal, administrative or investigative) by reason of the fact that
such person is or was a director or officer of this corporation, or is or was
serving at our request as a director or officer of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise,
against expenses (including attorney's fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding.

Item 8.           Exhibits
------

          Reference is made to the Exhibit Index.

Item 9.           Undertakings
------

          We hereby undertake:

          (1)  To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement 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, 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.
(4)  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 (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.

          (5)  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.
