CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT (a) (i) On August 1, 2002, the Company dismissed Arthur Andersen LLP as its independent accountants. (ii) The reports of Arthur Andersen LLP on the financial statements of the Company for each of the past two years contained no adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles other than the issue as to whether the Registrant will continue as a going concern and with respect to the Registrant not presenting quarterly financial data for the fiscal years ended August 31, 2000 and prior, that the Securities and Exchange Commission requires to supplement, although not required to be part of, the basic financial statements. (See also paragraph (v) below). (iii) The decision to change accountants was recommended by the Audit Committee of the Company's Board of Directors, and was approved by the Company's Board of Directors. (iv) During the Company's two most recent fiscal years and through the date of this report, there have not been any disagreements on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure which disagreements, if not resolved to the satisfaction of Arthur Andersen LLP would have caused them to make reference thereto in their report on the financial statements of the Company for such periods. (v) During the Company's two most recent fiscal years and through the date of this report, there were no "reportable events" as described in Item 304(a)(1)(v) of Regulation S-K, except as follows: Management has identified numerous critical issues which may require resolution prior to the Company's emergence from its reorganization proceedings. The Company has identified material deficiencies in many of its financial systems, processes and related internal controls and has commenced efforts to correct these conditions. During October 2000, Arthur Andersen LLP reported to the Audit Committee of the Board of Directors that the Company had material weaknesses in its internal controls and that these conditions would be considered in determining the nature, timing and extent of their audit tests for fiscal years 1997 through 2000. During September 2001 and March 2002, Arthur Andersen LLP reported to the Audit Committee that the identified material weaknesses continued to exist and would be considered in determining the nature, timing and extent of their audit tests for fiscal year 2001. The Company continues the process of correcting these conditions by filling key financial accounting and reporting positions in the organization, adding information technology controls and improving its financial system and processes. The Company intends to continue to utilize substantial internal and external resources to supplement these initiatives until it is satisfied that its internal controls no longer contain material weaknesses. The Company cannot estimate, at this time, how long it will take to completely develop and establish an adequate internal control environment. (vi) The Company requested that Arthur Andersen LLP furnish it with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the above statements. Arthur Andersen LLP has informed the Company that it is not able to respond to the Company's filing stating whether it agreed. (b) (i) Subject to the approval of the United States Bankruptcy Court for the District of Delaware, Deloitte & Touche LLP has been engaged by the Company as its new independent accountant to audit the Company's financial statements, effective as of August 1, 2002. Prior to the engagement of Deloitte & Touche LLP, the Company had not consulted with Deloitte & Touche LLP during its two most recent fiscal years and through the date of this report regarding (A) either the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's financial statements, and either a written report was provided to the Company or oral advice was provided that Deloitte & Touche LLP concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing, or financial reporting issue, or (B) the subject of either a disagreement or a reportable event described in Paragraph (a) (v) above.
