</TABLE>

(1)   1,627,141 shares of common stock issuable pursuant to various stock option
      plans of Maker Communications, Inc., which plans are being assumed by
      Conexant Systems, Inc. in connection with the merger of Maker
      Communications, Inc. with and into Conexant Systems, Inc. (the "Merger"),
      are being newly registered hereunder. The number of shares issuable
      pursuant to such plans has been calculated pursuant to the exchange ratio
      utilized in connection with the Merger. The newly registered shares are
      comprised of: (A) 1,132,636 shares issuable pursuant to outstanding grants
      under Maker Communications, Inc. 1996 Stock Option Plan (the "1996 Plan");
      (B) 0 shares issuable pursuant to outstanding grants under Maker
      Communications, Inc. 1999 Non-Employee Director Stock Option Plan (the
      "1999 Director Plan"); (C) 494,505 shares issuable pursuant to outstanding
      grants under the Maker Communications, Inc. 1999 Stock Incentive Plan (the
      "1999 Incentive Plan"). Pursuant to Rule 416 under the Securities Act of
      1933, as amended (the "Securities Act"), the amount registered hereunder
      includes an indeterminate number of shares of our common stock that may be
      issued in accordance with the provisions of such plans in connection with
      any anti-dilution provisions or in the event of any change in the
      outstanding shares of our common stock, including a stock dividend or
      stock split.

(2)   Pursuant to Rule 457 of the Securities Act, the Proposed Maximum Offering
      Price Per Share is based upon: (A) the weighted average exercise price per
      share ($4.35) of outstanding options for 1,132,636 shares under the 1996
      Plan; (B) the weighted average exercise price per share (N/A) of
      outstanding options for 0 shares under the 1999 Director Plan; (C) the
      weighted average exercise price per share ($38.86) of outstanding options
      for 494,505 shares under the 1999 Incentive Plan. In all cases, the
      weighted average exercise price per share has been calculated in
      accordance with the exchange ratio utilized in connection with the Merger.

(3)   Estimated solely for the purpose of calculating the registration fee
      pursuant to Rule 457 of the Securities Act.

(4)   This Registration Statement includes associated stock purchase rights
      under the Rights Agreement, dated as of November 30, 1998, by and between
      the Registrant and ChaseMellon Shareholder Services, LLC, as rights agent.
      Shares of our common stock being registered hereby are accompanied by such
      preference share purchase rights. Until the occurrence of specific
      prescribed events, such rights are not exercisable, are evidenced by the
      certificates for our common stock and will be transferred along with and
      only with our common stock. Upon the occurrence of such prescribed events,
      separate rights certificates will be issued representing one right for
      each share of common stock held, subject to adjustment pursuant to
      anti-dilution provisions.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

        The validity of the issuance of the shares of common stock registered
hereby has been passed upon for Conexant Systems, Inc. by Jasmina A. Theodore,
Esq., Associate General Counsel and Assistant Secretary of Conexant Systems,
Inc.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        The Delaware General Corporation Law (the "DGCL") permits Delaware
corporations to eliminate or limit the monetary liability of directors for
breach of their fiduciary duty of care, subject to certain limitations. The
Company's Restated Certificate of Incorporation provides that Company directors
are not liable to the Company or any of its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) for willful or negligent
violation of the laws governing the payment of dividends or the purchase or
redemption of stock, or (iv) for any transaction from which a director derived
an improper personal benefit.

        The DGCL allows for indemnification of directors, officers, employees
and agents subject to certain limitations. The Company's By-Laws, as amended,
and the appendix thereto provide for the indemnification of directors, officers,
employees and agents of the Company to the extent permitted by Delaware law.

        The Company has a directors' and officers' liability insurance policy
which insures the Company's directors and officers against certain liabilities
for actions taken in such capacities, including liabilities under the Securities
Act.

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;

            (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

                                      4

<PAGE>   5

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.

===============================================================================================================================
(1)   1,627,141 shares of common stock issuable pursuant to various stock option
      plans of Maker Communications, Inc., which plans are being assumed by
      Conexant Systems, Inc. in connection with the merger of Maker
      Communications, Inc. with and into Conexant Systems, Inc. (the "Merger"),
      are being newly registered hereunder. The number of shares issuable
      pursuant to such plans has been calculated pursuant to the exchange ratio
      utilized in connection with the Merger. The newly registered shares are
      comprised of: (A) 1,132,636 shares issuable pursuant to outstanding grants
      under Maker Communications, Inc. 1996 Stock Option Plan (the "1996 Plan");
      (B) 0 shares issuable pursuant to outstanding grants under Maker
      Communications, Inc. 1999 Non-Employee Director Stock Option Plan (the
      "1999 Director Plan"); (C) 494,505 shares issuable pursuant to outstanding
      grants under the Maker Communications, Inc. 1999 Stock Incentive Plan (the
      "1999 Incentive Plan"). Pursuant to Rule 416 under the Securities Act of
      1933, as amended (the "Securities Act"), the amount registered hereunder
      includes an indeterminate number of shares of our common stock that may be
      issued in accordance with the provisions of such plans in connection with
      any anti-dilution provisions or in the event of any change in the
      outstanding shares of our common stock, including a stock dividend or
      stock split.

(2)   Pursuant to Rule 457 of the Securities Act, the Proposed Maximum Offering
      Price Per Share is based upon: (A) the weighted average exercise price per
      share ($4.35) of outstanding options for 1,132,636 shares under the 1996
      Plan; (B) the weighted average exercise price per share (N/A) of
      outstanding options for 0 shares under the 1999 Director Plan; (C) the
      weighted average exercise price per share ($38.86) of outstanding options
      for 494,505 shares under the 1999 Incentive Plan. In all cases, the
      weighted average exercise price per share has been calculated in
      accordance with the exchange ratio utilized in connection with the Merger.

(3)   Estimated solely for the purpose of calculating the registration fee
      pursuant to Rule 457 of the Securities Act.

(4)   This Registration Statement includes associated stock purchase rights
      under the Rights Agreement, dated as of November 30, 1998, by and between
      the Registrant and ChaseMellon Shareholder Services, LLC, as rights agent.
      Shares of our common stock being registered hereby are accompanied by such
      preference share purchase rights. Until the occurrence of specific
      prescribed events, such rights are not exercisable, are evidenced by the
      certificates for our common stock and will be transferred along with and
      only with our common stock. Upon the occurrence of such prescribed events,
      separate rights certificates will be issued representing one right for
      each share of common stock held, subject to adjustment pursuant to
      anti-dilution provisions.

Esq., Associate General Counsel and Assistant Secretary of Conexant Systems,

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        The Delaware General Corporation Law (the "DGCL") permits Delaware
corporations to eliminate or limit the monetary liability of directors for
breach of their fiduciary duty of care, subject to certain limitations. The
Company's Restated Certificate of Incorporation provides that Company directors
are not liable to the Company or any of its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) for willful or negligent
violation of the laws governing the payment of dividends or the purchase or
redemption of stock, or (iv) for any transaction from which a director derived
an improper personal benefit.

        The DGCL allows for indemnification of directors, officers, employees
and agents subject to certain limitations. The Company's By-Laws, as amended,
and the appendix thereto provide for the indemnification of directors, officers,
employees and agents of the Company to the extent permitted by Delaware law.

        The Company has a directors' and officers' liability insurance policy
which insures the Company's directors and officers against certain liabilities
for actions taken in such capacities, including liabilities under the Securities
Act.

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;

            (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

                                      4
5

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.
