Item 5.  Other Material Information.

       Other than financial results for the periods ended on or before September
30, 2001, the financial information and other text of Exhibit 99.2 is comprised
of forward-looking information.  We cannot represent or assure anyone that the
information therein should be relied on for purposes of making an investment in
securities.  Goals, estimates, projections or beliefs may be based on unreliable
suppositions or incorrect premises.  Estimates are inherently subject to
inaccuracy, and our future financial condition and results may be significantly
different from our current expectations.

        Circumstances concerning expectations of potential orders are always
subject to rapid, adverse change.  Design wins are a preliminary indicator of
future sales; however design wins may not result in us actually realizing any
incremental revenues.

       Historic information is not necessarily a good indication of a continuing
or repeating trend.  Past results may not be repeatable.  In the process of
making our estimates, we make numerous assumptions that may prove wrong, based
on known or unknown factors.

       The information in Exhibit 99.2 may become inaccurate subsequent to the
date on which it is first presented.  We do not undertake to update such
information.  We intend to update or supersede such information on a quarterly
basis approximately, and not more frequently.

       Reference to such Exhibit 99.2 in this Item 5 does not incorporate such
information into this Item.  Exhibit 99.2 shall not be deemed reported in this
Item 5 or reported for purposes of the Securities Act of 1934, as amended,
except for reporting such information under Item 9 pursuant to Regulation FD.


Item 7.  Financial Statements and Exhibits.

       The Exhibit Index, which immediately follows the signatures hereto, is
incorporated herein by this reference.


Item 9.  Regulation FD Disclosure.

       On November 5, 2001 and November 6, 2001, the Registrant will make 45-

---------------------------------------------
presentations in the News Release attached hereto as Exhibit 99.1 and
incorporated herein by this reference.  On November 8, 2001, the Registrant will
make presentations to securities analysts at the Registrant's corporate
