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 thereof could not be filed within the prescribed time period. (Attach extra sheets if needed.) As previously disclosed in the Registrant's Form 8-K dated December 7, 1998, PricewaterhouseCoopers LLC ceased being the Registrant's principal accountant on December 1, 1998 and KPMG LLP became the Registrant's principal accountant on December 7, 1998. Although the Registrant has fully cooperated with KPMG LLP, KPMG LLP informed the Registrant on March 31, 1999, which was the deadline for filing the Registrant's Annual Report on Form 10-K ("Form 10-K"), that KPMG LLP would not release their audit report on March 31, 1999 because they had not yet completed their audit. PricewaterhouseCoopers LLP will not release their audit report until KPMG LLP's audit is completed. Therefore, the Registrant filed the Form 10-K on March 31, 1999 without the audit reports of KPMG LLP and PricewaterhouseCoopers LLP, and without the consents of KPMG LLP and PricewaterhouseCoopers LLP pursuant to Rule 12b-25(c).
