                              BROADCOM CORPORATION

                             STOCK OPTION AGREEMENT

RECITALS

    A. The Board has adopted the Plan for the purpose of retaining the services
of selected Employees, non-employee members of the Board or of the board of
directors of any Parent or Subsidiary and consultants and other independent
advisors who provide services to the Corporation (or any Parent or Subsidiary).

    B. Optionee is to render valuable services to the Corporation (or a Parent
or Subsidiary), and this Agreement is executed pursuant to, and is intended to
carry out the purposes of, the Plan in connection with the Corporation's grant
of an option to Optionee.

    C. All capitalized terms in this Agreement shall have the meaning assigned
to them in the attached Appendix.

    NOW, THEREFORE, it is hereby agreed as follows:

        1. GRANT OF OPTION. The Corporation hereby grants to Optionee, as of the
    Grant Date, an option to purchase up to the number of Option Shares
    specified in the Grant Notice. The Option Shares shall be purchasable from
    time to time during the option term specified in Paragraph 2 at the Exercise
    Price.

        2. OPTION TERM. This option shall have a maximum term of ten (10) years
    measured from the Grant Date and shall accordingly expire at the close of
    business on the Expiration Date, unless sooner terminated in accordance with
    Paragraph 5 or 6.

        3. LIMITED TRANSFERABILITY. This option shall be neither transferable
    nor assignable by Optionee other than by will or by the laws of descent and
    distribution following Optionee's death and may be exercised, during
    Optionee's lifetime, only by Optionee. However, if this option is designated
    a Non-Statutory Option in the Grant Notice, then this option may, in
    connection with the Optionee's estate plan, be assigned in whole or in part
    during Optionee's lifetime to one or more members of the Optionee's
    immediate family or to a trust established for the exclusive benefit of
    Optionee and/or one or more such family members. The assigned portion shall
    be exercisable only by the person or persons who acquire a proprietary
    interest in the option pursuant to such assignment. The terms applicable to
    the assigned portion shall be the same as those in effect for this option
    immediately prior to such assignment.

        4. DATES OF EXERCISE. This option shall become exercisable for the
    Option Shares in one or more installments as specified in the Grant Notice.
    As the option becomes exercisable for such installments, those installments
    shall accumulate, and the option shall remain exercisable for the
    accumulated installments until the Expiration Date or sooner termination of
    the option term under Paragraph 5 or 6. Notwithstanding the foregoing,
    should the Optionee elect to




    exercise this option during any period during which the Optionee is under
    investigation by the Corporation for Misconduct, then any Option Shares
    acquired by the Optionee as a result of such exercise and/or the net
    proceeds of any sale or sales of those acquired Option Shares (the gross
    sale proceeds less any Exercise Price payment or withholding taxes due the
    Corporation and broker commissions) during such period shall be held by the
    Corporation in escrow until such time as the investigation is satisfactorily
    completed.

        5. CESSATION OF SERVICE/TERMINATION OF OPTION. The option term specified
    in Paragraph 2 shall terminate (and this option shall cease to be
    outstanding) prior to the Expiration Date should any of the following
    provisions become applicable:

           (a) Should Optionee cease to remain in Service for any reason (other
        than death, Permanent Disability or Misconduct) while holding this
        option, then Optionee shall have a period of three (3) months
        (commencing with the date of such cessation of Service) during which to
        exercise this option, but in no event shall this option be exercisable
        at any time after the Expiration Date.

           (b) Should Optionee die while holding this option, then the personal
        representative of Optionee's estate or the person or persons to whom the
        option is transferred pursuant to Optionee's will or in accordance with
        the laws of inheritance shall have the right to exercise this option.
        Such right shall lapse, and this option shall cease to be outstanding,
        upon the earlier of (i) the expiration of the twelve (12)-month period
        measured from the date of Optionee's death or (ii) the Expiration Date.

           (c) Should Optionee cease Service by reason of Permanent Disability
        while holding this option, then Optionee shall have a period of twelve
        (12) months (commencing with the date of such cessation of Service)
        during which to exercise this option. In no event shall this option be
        exercisable at any time after the Expiration Date.

           (d) The applicable post-Service exercise period in effect for this
        option pursuant to the foregoing provisions of this Paragraph 5 shall
        automatically be extended by an additional period of time equal in
        duration to any interval within that otherwise applicable post-Service
        exercise period during which the exercise of this option or the
        immediate sale of the Option Shares acquired hereunder cannot be
        effected in compliance with applicable federal and state securities
        laws, but in no event shall such an extension result in the continuation
        of this option beyond the Expiration Date.

           (e) During the limited period of post-Service exercisability, this
        option may not be exercised in the aggregate for more than the number of
        vested Option Shares for which the option is exercisable at the time of
        Optionee's cessation of Service. Upon the expiration of such limited
        exercise period or (if earlier) upon the Expiration Date, this option
        shall terminate and cease to be outstanding for any vested Option Shares
        for which the option has not been exercised. However, except as set
        forth herein, this option shall, immediately upon Optionee's cessation
        of Service for any reason, terminate and cease to be outstanding with
        respect to any Option Shares in which Optionee is not otherwise at that
        time vested or for which this option is not otherwise at that time
        exercisable.


                                       2


           (f) Should Optionee's Service be terminated for Misconduct or should
        Optionee engage in Misconduct at any time Optionee holds this option,
        then this option shall terminate immediately and cease to remain
        outstanding.

        6. SPECIAL ACCELERATION OF OPTION.

        (a) This option to the extent outstanding at the time of a Change in
    Control but not otherwise fully exercisable, shall NOT become exercisable on
    an accelerated basis if and to the extent: (i) this option is, in connection
    with the Change in Control, to be assumed by the successor corporation (or
    parent thereof) or otherwise continued in full force and effect pursuant to
    the terms of the Change in Control transaction or (ii) this option is to be
    replaced with a cash incentive program of the successor corporation which
    preserves the spread existing at the time of the Change in Control on the
    Option Shares for which this option is not otherwise at that time
    exercisable (the excess of the Fair Market Value of those Option Shares over
    the aggregate Exercise Price payable for such shares) and provides for
    subsequent payout of that spread in accordance with the same option
    exercise/vesting schedule set forth in the Grant Notice. However, if none of
    the foregoing conditions apply to this option at the time of Change in
    Control, then this option shall automatically accelerate so that such option
    shall, immediately prior to the effective date of that Change in Control,
    become exercisable for all the shares of Common Stock at the time subject to
    this option and may be exercised for any or all of those shares as fully
    vested shares of Common Stock.

        (b) Immediately following the Change in Control, this option shall
    terminate and cease to be outstanding, except to the extent this option is
    assumed by the successor corporation (or parent thereof) in connection with
    the Change in Control or is otherwise to continue in full force and effect
    pursuant to the terms of the Change in Control transaction.

        (c) If this option is assumed in connection with a Change in Control or
    is otherwise to continue in full force and effect, then this option shall be
    appropriately adjusted, immediately after such Change in Control, to apply
    to the number and class of securities which would have been issuable to
    Optionee in consummation of such Change in Control had the option been
    exercised immediately prior to such Change in Control, and appropriate
    adjustments shall also be made to the Exercise Price, provided the aggregate
    Exercise Price shall remain the same. To the extent the actual holders of
    the Corporation's outstanding Common Stock receive cash consideration for
    their Common Stock in consummation of the Change in Control transaction, the
    successor corporation may, in connection with the assumption or continuation
    of this option, substitute one or more shares of its own common stock with a
    fair market value equivalent to the cash consideration paid per share of
    Common Stock in such Change in Control transaction.

        (d) This Agreement shall not in any way affect the right of the
    Corporation to adjust, reclassify, reorganize or otherwise change its
    capital or business structure or to merge, consolidate, dissolve, liquidate
    or sell or transfer all or any part of its business or assets.



                                       3


        7. ADJUSTMENT IN OPTION SHARES. Should any change be made to the Common
    Stock by reason of any stock split, stock dividend, recapitalization,
    combination of shares, exchange of shares or other change affecting the
    outstanding Common Stock as a class without the Corporation's receipt of
    consideration, appropriate adjustments shall be made to (i) the total number
    and/or class of securities subject to this option and (ii) the Exercise
    Price to reflect such change and thereby preclude a dilution or enlargement
    of benefits hereunder.

        8. SHAREHOLDER RIGHTS. The holder of this option shall not have any
    shareholder rights with respect to the Option Shares until such person shall
    have exercised the option, paid the Exercise Price and any required
    withholding taxes and become a holder of record of the purchased shares.

        9. MANNER OF EXERCISING OPTION.

        (a) To exercise this option with respect to all or any part of the
    Option Shares for which this option is at the time exercisable, Optionee (or
    any other person or persons exercising the option) must take the following
    actions:

            (i) Execute and deliver to the Corporation a Notice of Exercise for
        the Option Shares for which the option is exercised or comply with such
        other procedures as the Corporation may establish for notifying the
        Corporation of the exercise of this option for one or more Option
        Shares.

            (ii) Pay the aggregate Exercise Price for the purchased shares in
        one or more of the following forms:

                (A) cash or check made payable to the Corporation;

                (B) shares of Common Stock held by Optionee (or any other person
            or persons exercising the option) for the requisite period necessary
            to avoid a charge to the Corporation's earnings for financial
            reporting purposes and valued at Fair Market Value on the Exercise
            Date; or

                (C) through a special sale and remittance procedure pursuant to
            which Optionee (or any other person or persons exercising the
            option) shall concurrently provide irrevocable instructions (I) to a
            Corporation-designated brokerage firm(1) to effect the immediate
            sale of the purchased shares and remit to the Corporation, out of
            the sale proceeds available on the settlement date, sufficient funds
            to cover the aggregate Exercise Price payable for the purchased
            shares plus all applicable Federal, state and local income and
            employment taxes required to be withheld by the Corporation by
            reason of such exercise, and (II) to the Corporation to deliver the
            certificates for the purchased shares directly to such brokerage
            firm to complete the sale.


- --------

(1) With respect to Section 16 Insiders, the brokerage firm need only be
    reasonably satisfactory to the Corporation for purposes of administering
    such procedure.


                                       4


                  Except to the extent the sale and remittance procedure is
               utilized in connection with the option exercise, payment of the
               Exercise Price must accompany the Notice of Exercise delivered to
               the Corporation in connection with the option exercise.

            (iii) Furnish to the Corporation appropriate documentation that the
        person or persons exercising the option (if other than Optionee) have
        the right to exercise this option.

            (iv) Make appropriate arrangements with the Corporation (or Parent
        or Subsidiary employing or retaining Optionee) for the satisfaction of
        all Federal, state and local income and employment tax withholding
        requirements applicable to the option exercise.

        (b) As soon as practical after the Exercise Date, the Corporation shall
    issue to or on behalf of Optionee (or any other person or persons exercising
    this option) a certificate for the purchased Option Shares, with the
    appropriate legends affixed thereto.

        (c) In no event may this option be exercised for any fractional shares.

        10. COMPLIANCE WITH LAWS AND REGULATIONS.

        (a) The exercise of this option and the issuance of the Option Shares
    upon such exercise shall be subject to compliance by the Corporation and
    Optionee with all applicable requirements of law relating thereto and with
    all applicable regulations of any stock exchange (or the NASDAQ National
    Market(R), if applicable) on which the Common Stock may be listed for
    trading at the time of such exercise and issuance.

        (b) The inability of the Corporation to obtain approval from any
    regulatory body having authority deemed by the Corporation to be necessary
    to the lawful issuance and sale of any Common Stock pursuant to this option
    shall relieve the Corporation of any liability with respect to the
    non-issuance or sale of the Common Stock as to which such approval shall not
    have been obtained. The Corporation, however, shall use its best efforts to
    obtain all such approvals.

        11. SUCCESSORS AND ASSIGNS. Except to the extent otherwise provided in
    Paragraphs 3 and 6, the provisions of this Agreement shall inure to the
    benefit of, and be binding upon, the Corporation and its successors and
    assigns and Optionee, Optionee's assigns and the legal representatives,
    heirs and legatees of Optionee's estate.

        12. NOTICES. Any notice required to be given or delivered to the
    Corporation under the terms of this Agreement shall be in writing and
    addressed to the Corporation at its principal corporate offices. Any notice
    required to be given or delivered to Optionee shall be in writing and
    addressed to Optionee at the address indicated below Optionee's signature
    line on the Grant Notice. All notices shall be deemed effective upon
    personal delivery or upon deposit in the U.S. mail, postage prepaid and
    properly addressed to the party to be notified.



                                       5


        13. CONSTRUCTION. This Agreement and the option evidenced hereby are
    made and granted pursuant to the Plan and are in all respects limited by and
    subject to the terms of the Plan. The Plan Administrator shall have the
    discretionary authority to interpret and construe any term or provision of
    the Plan or this Agreement, and such interpretation shall be binding on all
    persons having an interest in this option.

        14. GOVERNING LAW. The interpretation, performance and enforcement of
    this Agreement shall be governed by the laws of the State of California
    without resort to that State's conflict-of-laws rules.

        15. MANDATORY ARBITRATION. ANY AND ALL DISPUTES OR CONTROVERSIES BETWEEN
    OPTIONEE AND THE CORPORATION ARISING OUT OF, RELATING TO OR OTHERWISE
    CONNECTED WITH THIS AGREEMENT OR THE OPTION EVIDENCED HEREBY OR THE
    VALIDITY, CONSTRUCTION, PERFORMANCE OR TERMINATION OF THIS AGREEMENT SHALL
    BE SETTLED EXCLUSIVELY BY BINDING ARBITRATION PURSUANT TO SECTION 12 OF
    APPENDIX I TO THE LETTER AGREEMENT BETWEEN OPTIONEE AND THE CORPORATION
    DATED OCTOBER 25, 2004, WHICH IS INCORPORATED BY REFERENCE HEREIN AS IF SET
    FORTH FULLY HEREIN.

        16. EXCESS SHARES. If the Option Shares covered by this Agreement
    exceed, as of the Grant Date, the number of shares of Common Stock which may
    without shareholder approval be issued under the Plan, then this option
    shall not become exercisable with respect to those excess shares, unless
    shareholder approval of an amendment sufficiently increasing the number of
    shares of Common Stock issuable under the Plan is obtained in accordance
    with the provisions of the Plan.

        17. ADDITIONAL TERMS APPLICABLE TO AN INCENTIVE OPTION. In the event
    this option is designated an Incentive Option in the Grant Notice, the
    following terms and conditions shall also apply to the grant:

            (a) This option shall cease to qualify for favorable tax treatment
        as an Incentive Option if (and to the extent) this option is exercised
        for one or more Option Shares: (A) more than three (3) months after the
        date Optionee ceases to be an Employee for any reason other than death
        or Permanent Disability or (B) more than twelve (12) months after the
        date Optionee ceases to be an Employee by reason of Permanent
        Disability.

            (b) No installment under this option shall qualify for favorable tax
        treatment as an Incentive Option if (and to the extent) the aggregate
        Fair Market Value (determined at the Grant Date) of the Common Stock for
        which such installment first becomes exercisable hereunder would, when
        added to the aggregate value (determined as of the respective date or
        dates of grant) of the Common Stock or other securities for which this
        option or any other Incentive Options granted to Optionee prior to the
        Grant Date (whether under the Plan or any other option plan of the
        Corporation or any Parent or Subsidiary) first become exercisable during
        the same calendar year, exceed One



                                       6


        Hundred Thousand Dollars ($100,000) in the aggregate. Should such One
        Hundred Thousand Dollar ($100,000) limitation be exceeded in any
        calendar year, this option shall nevertheless become exercisable for the
        excess shares in such calendar year as a Non-Statutory Option.

            (c) Should the exercisability of this option be accelerated upon a
        Change in Control, then this option shall qualify for favorable tax
        treatment as an Incentive Option only to the extent the aggregate Fair
        Market Value (determined at the Grant Date) of the Common Stock for
        which this option first becomes exercisable in the calendar year in
        which the Change in Control occurs does not, when added to the aggregate
        value (determined as of the respective date or dates of grant) of the
        Common Stock or other securities for which this option or one or more
        other Incentive Options granted to Optionee prior to the Grant Date
        (whether under the Plan or any other option plan of the Corporation or
        any Parent or Subsidiary) first become exercisable during the same
        calendar year, exceed One Hundred Thousand Dollars ($100,000) in the
        aggregate. Should the applicable One Hundred Thousand Dollar ($100,000)
        limitation be exceeded in the calendar year of such Change in Control,
        the option may nevertheless be exercised for the excess shares in such
        calendar year as a Non-Statutory Option.

            (d) Should Optionee hold, in addition to this option, one or more
        other options to purchase Common Stock which become exercisable for the
        first time in the same calendar year as this option, then for purposes
        of the foregoing limitations on the exercisability of such options as
        Incentive Options, this option and each of those other options shall be
        deemed to become first exercisable in that calendar year on the basis of
        the chronological order in which they were granted, except to the extent
        otherwise provided under applicable law or regulation.


                                       7

                             STOCK OPTION AGREEMENT

    The following provisions are hereby incorporated into, and are hereby made a
part of that certain Stock Option Agreement (the "Option Agreement") by and
between Broadcom Corporation, a California corporation (the "Corporation"), and
Scott A. McGregor ("Optionee") evidencing a stock option granted this day to
Optionee (the "Option") under the terms of the Corporation's 1998 Stock
Incentive Plan, as amended and restated (the "Plan"). The provisions of this
Addendum shall be effective immediately.

    Optionee has entered into an employment agreement with the Corporation
pursuant to that certain letter from the Corporation dated October 25, 2004 (the
"Letter Agreement"). The purpose of this Addendum is to supplement the terms of
the Option Agreement so that those terms conform to the special benefits to
which Optionee will become entitled pursuant to the terms of the Letter
Agreement.

    All capitalized terms in this Addendum, to the extent not otherwise defined
herein, shall have the meanings assigned to them in the Letter Agreement,
including Appendix II thereto.

                             SPECIAL OPTION BENEFITS

    1. If either the Corporation terminates Optionee's employment in a Notice of
Termination specifying no reason or a reason other than Cause or Disability, or
Optionee terminates his employment with the Corporation in a Notice of
Termination specifying Good Reason, and Optionee's employment has not terminated
automatically as a result of Optionee's death, then Optionee shall immediately
become entitled to the following additional benefits to the extent the Option is
at that time outstanding:

        (i) Optionee shall, immediately on the Date of Termination, be credited
    with an additional twenty-four (24) months of employment with the
    Corporation for purposes of the vesting schedule in effect for the Option so
    that Optionee shall be immediately vested in the Option to the same extent
    as if Optionee had completed an additional twenty-four (24) months of
    employment with the Corporation prior to the Date of Termination, and

        (ii) the Option shall remain exercisable, for any or all of the shares
    in which Optionee is vested on the Date of Termination (including the shares
    which vest on an accelerated basis in accordance with subparagraph (i)
    above), until the EARLIER of (A) the expiration of the twenty-four
    (24)-month period measured from the Date of Termination or (B) the specified
    expiration date of the Option term.

    2. If Optionee's employment is terminated by reason of death or Disability,
then Optionee shall, immediately on the Date of Termination, become fully vested
in the Option (to the extent outstanding on such date) and the Option shall
remain exercisable until the EARLIER of (A) the expiration of the twelve
(12)-month period measured form the Date of Termination or (B) the specified
expiration date of the Option term.




    3. To the extent any of the benefits provided pursuant to this Addendum
shall be deemed to constitute a parachute payment under Section 280G of the
Internal Revenue Code, then those benefits shall be subject to the parachute
payment limitation provisions of the Letter Agreement.

    4. In no event shall Optionee be entitled to any benefits pursuant to this
Addendum unless (i) Optionee shall have executed and delivered to the
Corporation the separation agreement required under Paragraph 11 of Appendix II
to the Letter Agreement and (ii) Optionee is in material compliance with his
obligations to the Corporation pursuant to his Confidentiality and Invention
Assignment Agreement during and subsequent to Optionee's employment.

    5. To the extent the provisions of this Addendum conflict with the
provisions of the Option Agreement (including, without limitation, the
provisions of Paragraph 5 of such Option Agreement), the provisions of this
Addendum shall be controlling.

    6. Except to the extent modified by this Addendum, all the terms and
conditions of the Option Agreement shall continue in full force effect.

    7. Optionee hereby acknowledges that the Option shall cease to qualify for
favorable tax treatment as an incentive stock option under the federal tax laws
(if the Option is designated as an Incentive Stock Option in the Notice of Grant
of Stock Option relating to such Option) if (and to the extent) the Option is
exercised: (A) more than three (3) months after the date Optionee ceases to be
an Employee for any reason other than death or Permanent Disability or (B) more
than twelve (12) months after the date Optionee ceases to be an Employee by
reason of Permanent Disability. For purposes of this Paragraph 7, the terms
"EMPLOYEE" and "PERMANENT DISABILITY" shall have the meanings assigned to them
in the Option Agreement.

         IN WITNESS WHEREOF, BROADCOM CORPORATION has caused this Addendum to be
executed by its duly-authorized officer, and Optionee has executed this
Addendum, all as of the Effective Date specified below.
