                                     PART II
                             RULE 12b-25(b) AND (c)

         If the subject report could not be filed without unreasonable effort or
         expense and the registrant seeks relief pursuant to Rule 12b-25(b), the
         following should be completed. (Check box if appropriate)

[X]               (a) The reasons described in reasonable detail in Part III of
                  this form could not be eliminated without unreasonable effort
                  or expense;

[X]               (b) The subject annual report or semi-annual report,
                  transition report on Form 10-K, 11-K or Form N-SAR, or portion
                  thereof will be filed on or before the 15th calendar day
                  following the prescribed due date; or the subject quarterly
                  report or transition report on Form 10-Q, or portion thereof
                  will be filed on or before the fifth calendar day following
                  the prescribed due date; and

[ ]               (c) The accountant's statement or other exhibit required by

                                    PART III
                                    NARRATIVE

         State below in reasonable detail the reasons why the Form 10-K, 11-K,
         20-F, 10-Q, N-SAR or the transition report portion thereof could not be
         filed within the prescribed time period.

         On May 9, 2003, the Company filed its annual report on Form 10-K for
the year ended December 31, 2002. The Company's Form 10-K was reviewed by the
United States Securities and Exchange Commission (the "SEC"). The Company's Form
10-K/A was released for filing by the SEC on or about October 17, 2003. In
addition, on November 6, 2003, the Company announced the implementation of a
restructuring of its operations, including the closure of a number of sites and
substantial employee layoffs. The delay in the filing of the Form 10-K/A
combined with the review of the impact of the restructuring on the Company's
financial statements delayed the availability of financial information required
to complete and file the Form 10-Q for the fiscal quarter ended September 30,
2003. Management anticipates the preparation and filing of Company's Form 10-Q
for the fiscal quarter ended September 30, 2003 on or before the 5th calendar
day following its prescribed due date.

                                     PART IV
                                OTHER INFORMATION

         (1)      Name and telephone number of person to contact in regard to
                  this notification:

                  Peter Clemens, Chief Financial Officer      (815)     399-2060
                  --------------------------------------------------------------
                  (Name )                         (Area Code) (Telephone Number)


         (2)      Have all other periodic reports required
                  under Section 13 or 15(d) of the Securities
                  Exchange Act of 1934 or Section 30 of the
                  Investment Company Act of 1940 during the      [X ] Yes No [ ]
                  preceding 12 months or for such shorter
                  period that the registrant was required
                  to  file such report(s) been filed?
                  If the answer is no, please identify report(s).

         (3)      Is it anticipated that any significant
                  change in results of operations from the       [ ] Yes No [X ]
                  corresponding period for the last fiscal
                  year will be reflected by the earnings
                  statements to be included in the subject
                  report or portion thereof?

                  If so: attach an explanation of the anticipated change, both
                  narratively and quantitatively, and, if appropriate, state the
                  reasons why a reasonable estimate of the results cannot be
                  made.
