     [X]       (a)  The reasons described in reasonable detail in Part III of

                    effort or expense;

                    report on Form 10-K, 20-F, 11-K or Form N-SAR, or portion

                              PART III - NARRATIVE

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

     The Company requires additional time to adequately develop certain
     financial information to be contained in its Quarterly Report on Form 10-Q
     for the quarter ended September 30, 2002. As a result, the Company has been
     unable to complete its Form 10-Q for the quarter ended September 30, 2002
     within the prescribed time period without unreasonable effort or expense.

                           PART IV - OTHER INFORMATION

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

     Catherine Cuisson                   (803)                     643-1501
- --------------------------------------------------------------------------------
     (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 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, identify report(s).

                                                      [X]  Yes     [_]  No

- --------------------------------------------------------------------------------
(3)  Is it anticipated that any significant change in results of operations from
     the corresponding period for the last fiscal year will be reflected by the
     earnings statements to be included in the subject report or portion
     thereof?

                                                      [X]  Yes     [_]  No

     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.

     It is anticipated that significant changes in the results of operations for
     the Company's quarter ended September 30, 2002, as compared to the
     corresponding period for the prior year, will be reflected in the financial
     statements of the Company to be filed as part of the Company's quarterly
     report on Form 10-Q for the quarter ended September 30, 2002. The Company
     expects to report that its net sales decreased approximately $8-9 million,
     or approximately 16-19%, to approximately $40-41 million in the three
     months ended September 30, 2002, from $48.9 million in the three months
     ended September 30, 2001, and the Company expects to incur a net loss for
     the three months ended September 30, 2002, but that the magnitude of such
     loss cannot be determined at this time because the Company is currently
     considering whether it would be appropriate to take a charge for an
     impairment on the value of its fixed assets.

     The Company also expects to report that its net sales decreased
     approximately $39-40 million, or approximately 22-23%, to approximately
     $133-134 million in the nine months ended September 30, 2002, from $172.9
     million in the nine months ended

     September 30, 2001, and the Company expects to incur a net loss for the
     nine months ended September 30, 2002, but that the magnitude of such loss
     cannot be determined at this time because the Company is currently
     considering whether it would be appropriate to take a charge for an
     impairment on the value of its fixed assets. The aforementioned amounts are
     estimates only and may be subject to further adjustment.
