(2) The consolidated balance sheet at March 31, 2005 has been
derived from the Company's audited consolidated financial statements
on Form 10-K at that date, but does not include all of the information
and footnotes required by generally accepted accounting principles for
complete financial statements.
(3) The consolidated balance sheet at December 31, 2005 reflects the
impact of the additional income tax benefit described below.


     Increase in Historical Earnings due to Tax Benefit

     As a result of the recent completion and filing of our fiscal 2005 federal
and California income tax returns, we have revised the amount of our Research
and Development tax credits. This revision increases our tax benefit and net
income for our first quarter of fiscal 2006 by $1,891,000 and increases earnings
per share for that quarter from the $0.15 previously reported to $0.21. The
impact of this revision is reflected in the results for the nine months ended
December 31, 2005 provided herewith. We plan to file amended Quarterly Reports
on Form 10-Q for the first and second quarters ended June 30, 2005 and September
30, 2005, originally filed with the Securities and Exchange Commission on August
15, 2005 and November 9, 2005, respectively, to reflect this change and to
restate the financial statements for those periods.
