(attach extra sheets if needed.) The Company was not able to timely file certain information responsive to Items 1, 2 and 3 of Part I of Form 10-Q and portions of other Items which elicit financial information as required to be filed pursuant to Sections 13 or 15(d) of the Securities Exchange Act of 1934, as amended, and the rules thereunder. The required Form 10-Q of the Company was to cover the quarterly period ended November 30, 2001. The Company, with the assistance of Jefferson Wells International and Arthur Andersen LLP, is working to correct material deficiencies in the Company's internal controls. Despite the progress made by the Company in correcting the deficiencies, the Company was not able to prepare its financial statements for the fiscal quarter ended November 30, 2001 within the time limitations imposed by federal securities laws and regulations. At such time as the financial statements for the fiscal quarter ended November 30, 2001 have been prepared, the Company intends to amend its Form 10-Q for the quarter ended November 30, 2001, file the financial statements required by Form 10-Q and provide the information which was omitted in its Form 10-Q filing. The Company anticipates making that filing as soon as practicable. The Company hereby confirms that the circumstances relating to the delay in the completion of the omitted portions of the report on Form 10-Q could not have been eliminated by the Company without unreasonable effort and expense. PART IV OTHER INFORMATION (1) Name and telephone number of person to contact in regard to this notification. Larry W. Singleton (803) 933-4360 - ------------------ ------------------------- (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 answer is no, identify report(s) | |Yes |X|No The Company did not file all of the items required in its Form 10-K for the period ended August 31, 2001. (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. The Company's amended Form 10-Q for the period ended May 31, 2001, filed on September 28, 2001, included financial results for the periods ended November 30, 2000, February 28, 2001 and May 31, 2001. For the period ended November 30, 2001 first quarter net loss of $57.7 million. Items which significantly contributed to the first quarter net loss for the period ended November 30, 2000 were "Provision for early facility closures" of approximately $9.5 million, and a charge of approximately $6.7 million for adjusting certain environmental liabilities. The Company does not expect to incur these charges in the first quarter of fiscal 2002. A reasonable estimate of the results cannot be made at this time because the Company's books have not yet closed for the fiscal year ended August 31, 2001 and the fiscal period ended November 30, 2001.
