              INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE.

     The following documents are incorporated by reference into this
Registration Statement:

     (1) The registrant's Registration Statement on Form S-1 (Registration No.
333-32735), as amended (the "Registration Statement"), which has heretofore
been filed with the Commission pursuant to the Securities Act of 1933, as
amended (the "Act").

     (2) The registrant's 424(b) prospectus relating to the Registration
Statement filed with the Commission pursuant to the Act.

     (3) The description of the registrant's Common Stock contained in the
registrant's Registration Statement on Form 8-A filed with the Commission
pursuant to Section 12(g) of the Securities Exchange Act of 1934, as amended
(the "1934 Act").

     (4) The registrant's quarterly report on Form 10-Q for the fiscal quarter
ended September 30, 1997.

     All documents subsequently filed by the registrant pursuant to Sections
13(a), 13(c), 14 and 15(d) of the 1934 Act, 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, shall be deemed
to be incorporated by reference into this Registration Statement and to be a
part hereof from the date of filing of such documents (such documents, and the
documents enumerated above, being hereinafter referred to as the "Incorporated
Documents"); provided, however, that the documents enumerated above or
subsequently filed with the Commission pursuant to Sections 13(a), 13(c), 14
and 15(d) of the 1934 Act in each year during which the offering made by this
Registration Statement is in effect prior to the filing with the Commission of
the registrant's Annual Report on Form 10-K covering such year shall not be
Incorporated Documents or be incorporated by reference into this Registration
Statement or be a part hereof from and after the filing of such Annual Report
on Form 10-K

     Any statement contained in an Incorporated Document shall be deemed to be
modified or superseded for purposes of this Registration Statement to the
extent that a statement contained herein or in any subsequently filed
Incorporated Document modifies or supersedes such statement.  Any such
statement so modified or superseded shall not be deemed, except as so modified
or superseded, to constitute a part of this Registration Statement.

1934 Act.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

     The validity of the issuance of the shares of Common Stock offered hereby
will be passed upon for the registrant by Wildman, Harrold, Allen & Dixon,
Chicago, Illinois.  Donald E. Figliulo, a partner of Wildman, Harrold, Allen &
Dixon, is the owner of approximately one percent of the registrant's issued and
outstanding Common Stock, and is the brother of Robert M. Figliulo, the
registrant's Chairman of the Board and Chief Executive Officer, and of David A.
Figliulo, the registrant's Executive Vice President and a Director.

ITEM 6.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.

     The registrant, being incorporated under the General Corporation Law of
the State of Delaware (the "DGCL"), is empowered by Section 145 of the DGCL,
subject to the procedures and limitations stated therein, to indemnify any
person against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually incurred by him or her in connection with
any threatened, pending or completed action, suit or proceeding to which such
person is made a party or threatened to be made a party by reason of the fact
that he or she is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise.  Section 145 provides that indemnification
pursuant to its provisions is not exclusive of other rights of indemnification
to which a person may be entitled under any by-law, agreement, vote of
stockholders or disinterested directors or otherwise.

     The registrant's Certificate of Incorporation and By-Laws contain
provisions which require the registrant to indemnify its directors and officers
to the fullest extent permitted by the DGCL.

     The registrant's Certificate of Incorporation contains a provision which
eliminates, to the fullest extent permitted by Delaware law, the personal
liability of each director of the registrant to the registrant and its
stockholders for monetary damages for certain breaches of fiduciary duty.  This
provision does not affect the director's liability for monetary damages for (i)
breaches of the duty of loyalty, (ii) actions or omissions not in good faith or
which involve knowing violations of law or intentional misconduct, (iii)
willful or negligent conduct in approving an unlawful dividend, stock
repurchase or redemption or (iv) for any transaction from which the director
derived any improper personal benefit.

     The registrant maintains directors and officers liability insurance
covering all directors and officers of the registrant against claims arising
out of the performance of their duties.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

     Not applicable.

ITEM 8.  EXHIBITS.

      Reference is made to the Exhibit Index.

ITEM 9.  UNDERTAKINGS.
 
      The 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;

     (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; and

     (iii) To include any material information with respect to the plan of
distribution not previously disclosed in this Registration Statement or any
material change to such information in this Registration Statement;

provided, however, that paragraphs (1)(i) and (1)(ii) above do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in this Registration Statement.

     (2) That, for the purpose of determining any liability under the 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 which remain unsold at the termination of the offering;

     (4) That, for purposes of determining any liability under the Act, each
filing of the registrant's annual report pursuant to section 13(a) or 15(d) of
the 1934 Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the 1934 Act) that is incorporated
by reference into this Registration Statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities shall be deemed to be the initial bona fide
offering thereof; and

     (5) Insofar as indemnification for liabilities arising under the Act may
be permitted to directors, officers and controlling persons of the registrant
pursuant to the provisions described in Item 6 or otherwise, the registrant has
been advised that in the opinion of the


                                      -4-

<PAGE>   5

     Commission such indemnification is against public policy as expressed in
the Act and is thus 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 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

     The validity of the issuance of the shares of Common Stock offered hereby
will be passed upon for the registrant by Wildman, Harrold, Allen & Dixon,
Chicago, Illinois.  Donald E. Figliulo, a partner of Wildman, Harrold, Allen &
Dixon, is the owner of approximately one percent of the registrant's issued and
outstanding Common Stock, and is the brother of Robert M. Figliulo, the
registrant's Chairman of the Board and Chief Executive Officer, and of David A.
Figliulo, the registrant's Executive Vice President and a Director.

ITEM 6.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.

     The registrant, being incorporated under the General Corporation Law of
the State of Delaware (the "DGCL"), is empowered by Section 145 of the DGCL,
subject to the procedures and limitations stated therein, to indemnify any
person against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually incurred by him or her in connection with
any threatened, pending or completed action, suit or proceeding to which such
person is made a party or threatened to be made a party by reason of the fact
that he or she is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise.  Section 145 provides that indemnification
pursuant to its provisions is not exclusive of other rights of indemnification
to which a person may be entitled under any by-law, agreement, vote of
stockholders or disinterested directors or otherwise.

     The registrant's Certificate of Incorporation and By-Laws contain
provisions which require the registrant to indemnify its directors and officers
to the fullest extent permitted by the DGCL.

     The registrant's Certificate of Incorporation contains a provision which
eliminates, to the fullest extent permitted by Delaware law, the personal
liability of each director of the registrant to the registrant and its
stockholders for monetary damages for certain breaches of fiduciary duty.  This
provision does not affect the director's liability for monetary damages for (i)
breaches of the duty of loyalty, (ii) actions or omissions not in good faith or
which involve knowing violations of law or intentional misconduct, (iii)
willful or negligent conduct in approving an unlawful dividend, stock
repurchase or redemption or (iv) for any transaction from which the director
derived any improper personal benefit.

     The registrant maintains directors and officers liability insurance
covering all directors and officers of the registrant against claims arising
out of the performance of their duties.

ITEM 9.  UNDERTAKINGS.
 
      The 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;

     (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; and

     (iii) To include any material information with respect to the plan of
distribution not previously disclosed in this Registration Statement or any
material change to such information in this Registration Statement;

provided, however, that paragraphs (1)(i) and (1)(ii) above do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in this Registration Statement.

     (2) That, for the purpose of determining any liability under the 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 which remain unsold at the termination of the offering;

     (4) That, for purposes of determining any liability under the Act, each
filing of the registrant's annual report pursuant to section 13(a) or 15(d) of
the 1934 Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the 1934 Act) that is incorporated
by reference into this Registration Statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities shall be deemed to be the initial bona fide
offering thereof; and

     (5) Insofar as indemnification for liabilities arising under the Act may
be permitted to directors, officers and controlling persons of the registrant
pursuant to the provisions described in Item 6 or otherwise, the registrant has
been advised that in the opinion of the

                                      -4-
5

     Commission such indemnification is against public policy as expressed in
the Act and is thus 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.
