ITEM 9. REGULATION FD DISCLOSURE

     This  information  is being  furnished  pursuant  to Item 12 -  RESULTS  OF
OPERATIONS AND FINANCIAL CONDITION - as provided in SEC Release No. 34-47583.

     On July 17, 2003, we announced  the results of  operations  for the quarter
ended June 30, 2003. The complete  release is attached to this report as Exhibit
99.1.

     Our press release includes information  regarding certain of our historical
results  on a pro forma  basis (a  non-GAAP  financial  measure).  Our pro forma
results  for the first  quarter of fiscal 2004  excludes  the effects of special
charges  of $33.4  million  which  consisted  of $30.6  million  of  accelerated
depreciation  relating  to the closure of Fab 1 and $2.8  million of  additional
charges  principally  for contract  cancellation,  severance,  and other related
costs.  We believe  that the pro forma  data  provides  investors  with a useful
representation  of our core  ongoing  performance,  and a helpful  baseline  for
assessing our future earnings potential.
