     of such plan in connection with any anti-dilution provision or in the event
     of any change in the outstanding shares of Common Stock, including a stock
     dividend or stock split.

     Price Per Share is based upon the weighted average exercise price per share
     ($12.81) of outstanding options for 225,169 shares granted under the plan.
     The weighted average exercise price per share has been calculated in
     accordance with the exchange ratio (0.0724) used in connection with the

         Dennis E. O'Reilly, Esq., who has passed upon the legality of any newly

Company.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Delaware General Corporation Law permits Delaware corporations to
eliminate or limit the monetary liability of directors for breach of their
fiduciary duty of care, subject to certain limitations. Our restated certificate
of incorporation provides that our directors are not liable to the Conexant or
its shareowners for monetary damages for breach of fiduciary duty as a director,
except for liability (1) for any breach of the director's duty of loyalty to
Conexant or its shareowners, (2) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (3) for
willful or negligent violation of the laws governing the payment of dividends or
the purchase or redemption of stock or (4) for any transaction from which a
director derived an improper personal benefit.

         The Delaware General Corporation Law provides for indemnification of
directors, officers, employees and agents subject to certain limitations. Our
by-laws and the appendix thereto provide for the indemnification of our
directors, officers, employees and agents to the extent permitted by Delaware
law. Our directors and officers are insured against certain liabilities for
actions taken in such capacities, including liabilities under the Securities
Act.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.

ITEM 9.  UNDERTAKINGS.

         The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

                  (i) To include any prospectus required by Section 10(a)(3) of
the Securities Act of 1933, as amended (the "Securities Act");

                  (ii) To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in the volume
of securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price set forth in the "Calculation of Registration Fee"
table in the effective registration statement;

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement.

Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Securities and Exchange Commission by the registrant pursuant to Section 13 or
Section 15(d) of the Exchange Act that are incorporated by reference in the
registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer, or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

Company.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Delaware General Corporation Law permits Delaware corporations to
eliminate or limit the monetary liability of directors for breach of their
fiduciary duty of care, subject to certain limitations. Our restated certificate
of incorporation provides that our directors are not liable to the Conexant or
its shareowners for monetary damages for breach of fiduciary duty as a director,
except for liability (1) for any breach of the director's duty of loyalty to
Conexant or its shareowners, (2) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (3) for
willful or negligent violation of the laws governing the payment of dividends or
the purchase or redemption of stock or (4) for any transaction from which a
director derived an improper personal benefit.

         The Delaware General Corporation Law provides for indemnification of
directors, officers, employees and agents subject to certain limitations. Our
by-laws and the appendix thereto provide for the indemnification of our
directors, officers, employees and agents to the extent permitted by Delaware
law. Our directors and officers are insured against certain liabilities for
actions taken in such capacities, including liabilities under the Securities
Act.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

ITEM 9.  UNDERTAKINGS.

         The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

                  (i) To include any prospectus required by Section 10(a)(3) of
the Securities Act of 1933, as amended (the "Securities Act");

                  (ii) To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in the volume
of securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price set forth in the "Calculation of Registration Fee"
table in the effective registration statement;

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement.

Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Securities and Exchange Commission by the registrant pursuant to Section 13 or
Section 15(d) of the Exchange Act that are incorporated by reference in the
registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer, or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
