                   WITHDRAWAL OF SECURITIES FROM REGISTRATION

         On July 7, 1999, Conexant Systems, Inc., a Delaware corporation
("Conexant"), filed a Registration Statement on Form S-3 (No. 333-82399) (the
"Registration Statement") for purposes of registering resales of $350,000,000
aggregate principal amount of Conexant's 4-1/4% Convertible Subordinated Notes
due May 1, 2006 (the "Notes") and 15,152,826 shares (as adjusted to reflect the
two-for-one stock split effected on October 29, 1999) of Conexant's common
stock, par value $1 per share, (including the associated preferred share
purchase rights) into which the Notes are convertible (the "Conversion Shares").
On July 26, 1999, Conexant filed Amendment No. 1 to the Registration Statement
and on July 28, 1999, the Commission declared the Registration Statement
effective. Since that time and from time to time, Conexant has filed prospectus
supplements under the Registration Statement for the benefit of holders of the
Notes and the Conversion Shares not previously included as "Selling
Securityholders" under the Registration Statement.

         Pursuant to the terms of the Registration Rights Agreement that
required Conexant to file the Registration Statement, Conexant is no longer
required to keep the Registration Statement effective. Accordingly, this
Post-Effective Amendment No. 1 to the Registration Statement is being filed to
withdraw from registration under the Securities Act of 1933, as amended, as of
the date hereof, all of the Notes and the Conversion Shares that remain unsold
under the Registration Statement.

         Pursuant to the requirements of the Securities Act of 1933, as amended,
the registrant certifies that it has reasonable grounds to believe that it meets
all of the requirements for filing on Form S-3 and has duly caused this
Post-Effective Amendment No. 1 to the Registration Statement to be signed on its
behalf by the undersigned, thereunto duly authorized, in the City of Newport
Beach, State of California on June 20, 2001.
