Item 9. Regulation FD Disclosure.

On March 6, 2001, Registrant revised its current guidance for future periods, as
follows: Registrant expects sales in its third quarter ending March 31, 2001 to
be approximately $925 million with pro forma earnings per share of approximately
$0.14. Fourth quarter guidance (for the quarter ending June 30, 2001) now is for
sales and pro forma earnings per share to be approximately at the same levels as
the third quarter or slightly above those levels. Registrant has not provided
guidance for the fiscal year ending June 30, 2002. Registrant's revised
guidance, which is lower than guidance previously provided for the periods,
reflects continued uncertainty in carrier capital spending prospects and
customer inventory adjustments as well as a lower level of near-term sales
visibility than Registrant has experienced in recent periods.

The statements contained in this press release relating to sales, pro forma
earnings, and sales visibility are forward-looking statements within the meaning
of Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. These forward-looking statements involve risks and
uncertainties that could cause actual results to differ materially from those
projected for Registrant. Risks and uncertainties that could cause actual
results to differ materially from these forward-looking statements include the
levels of carrier capital spending and customer inventory adjustments as well as
near-term sales visibility. Additional factors that could cause actual results
to differ materially are discussed from time to time in reports filed by
Registrant with the Securities and Exchange Commission. The forward-looking
statements contained in this report are made as of the date hereof and
Registrant does not assume any obligation to update the reasons why actual
results could differ materially from those projected in the forward-looking
statements.
