ITEM 4.02 NON-RELIANCE ON PREVIOUSLY ISSUED FINANCIAL STATEMENTS OR A RELATED
AUDIT REPORT OR COMPLETED INTERIM REVIEW.

On August 1, 2005, management of the Company advised the Company's Audit
Committee that it had made a determination that its method of accounting for
certain new product research and development costs was inconsistent with
generally accepted accounting principles. Management and the Audit Committee
also discussed this matter with the Company's independent registered public
accounting firm, Deloitte & Touche LLP. As a result, the Audit Committee concurs
with management's conclusion that the prior accounting for new product research
and development costs was in error and will require a restatement of its
financial statements for the quarters ended September 30, 2004, December 31,
2004 and March 31, 2005. The restatement relates to the accounting treatment of
certain new product research and development costs (initial wafer production
costs) that were incorrectly capitalized into inventory. Accordingly, the
Company has determined that its previously issued financial statements for the
quarters ended September 30, 2004, December 31, 2004 and March 31, 2005, should
no longer be relied upon.

The Company anticipates filing the corrections to its financial statements in
conjunction with the filing of its Annual Report of Form 10-K for the year ended
June 30, 2005.

Management is considering the effect of these restatements on its evaluation of
disclosure controls and procedures and internal controls over financial
reporting.

The press release issued on August 2, 2005 by the Company is attached hereto as
Exhibit 99.1.

ITEM 9.01. FINANCIAL STATEMENTS AND EXHIBITS.
