EX-101 INSTANCE DOCUMENT

Exhibit 10.1

August 3, 2009

Mr. Scott McGregor
President and Chief Executive Officer
Broadcom Corporation
5300 California Avenue
Irvine, CA 92617

Dear Scott:

     On October 25, 2004, you entered into an employment agreement with Broadcom Corporation (“Broadcom”) in the form of a detailed offer letter (the “Employment Agreement”). The Employment Agreement was subsequently amended on December 16, 2005 to revise the provisions of the agreement relating to the stock-based awards that were to be made to you on the first anniversary of your start date. Appendix II to your Employment Agreement sets forth the various severance benefits to which you may become entitled should your employment with Broadcom terminate under certain defined circumstances (the “Severance Program”).

     Pursuant to your letter agreement with Broadcom dated August 12, 2008 (the “2008 Letter Agreement”), the provisions of Appendix II governing your Severance Program were revised to (i) bring those terms and provisions into compliance with the applicable requirements of the final Treasury Regulations under Section 409A (“Section 409A”) of the Internal Revenue Code of 1986, as amended (the “Code”), and (ii) effect certain substantive changes authorized by the Compensation Committee of the Broadcom Board of Directors (the “Compensation Committee”). The purpose of this new letter agreement (the “New Agreement”) is to effect certain additional changes to Appendix II necessary to comply with developments in the laws and regulations applicable to the Severance Program and to clarify certain provisions governing post-employment coverage under certain Broadcom employee benefit plans. Except for those changes to the Severance Program, the terms and conditions set forth in this New Agreement are substantially the same as those in effect under the 2008 Letter Agreement.

     Appendix II as currently in effect under your 2008 Letter Agreement is hereby superseded by new Appendix II set forth below and shall cease to have any force or effect upon your execution of this New Agreement. All the other terms and provisions of your Employment Agreement, as modified by the December 16, 2005 amendment, shall remain in full force and effect and shall not in any way be revised, modified or amended by any provision of this New Agreement.

REVISED APPENDIX II — SEVERANCE BENEFIT PROGRAM

     This revised Appendix II sets forth the terms and conditions of the revised Severance Program that is to be effect under your Employment Agreement as modified by this New Agreement and is to be construed in conjunction with, and is made a part of, that Employment Agreement effective upon your execution of this New Agreement. Capitalized terms not defined in this revised Appendix II shall have the meanings defined elsewhere in the Employment Agreement.

     1. Severance Benefits upon Certain Terminations. Should your employment with Broadcom be terminated by you in a Notice of Termination specifying Good Reason, or should such employment be terminated by Broadcom in a Notice of Termination specifying no reason or a reason other than (i) Cause or (ii) your Disability, and in either instance your employment is not otherwise terminated automatically as a result of your death, then Broadcom shall make the payments and provide the benefits described below, provided that with respect to certain of those benefits, there is compliance with each of the following requirements (the “Severance Benefit Requirements”):

          (i) you deliver the general release required under Section 2 of this Appendix II (the “Required Release”) within the applicable time period following your Date of Termination,

          (ii) the Required Release becomes effective in accordance with applicable law following the expiration of any applicable revocation period,

          (iii) you comply with each of the restrictive covenants set forth in Section 4 of this Appendix II, and

          (iv) you are and continue to remain in material compliance with your obligations to Broadcom under your Confidentiality and Invention Assignment Agreement.

     The payments and benefits to which you will become entitled if all the Severance Benefits Requirements are satisfied are as follows:

     (a) Cash Severance. Broadcom will pay you cash severance (“Cash Severance”) in an amount equal to three (3) times the sum of (A) your annual rate of base salary (using your then current rate or, if you terminate your employment for Good Reason pursuant to Subsection 9(b) of this Appendix II due to an excessive reduction in your base salary, then your rate of base salary immediately before such reduction) and (B) the average of your actual annual bonuses for the three calendar years (or such fewer number of calendar years of employment with Broadcom) immediately preceding the calendar year in which such termination of employment occurs. Such Cash Severance shall be payable over a thirty-six (36)-month period in successive equal bi-weekly or semi-monthly installments in accordance with the payment schedule in effect for your base salary on your Date of Termination. Subject to the deferral provisions of Section 3 below, the Cash Severance payments will begin on the first regular pay day, within the

sixty (60)-day period measured from the date of your Separation from Service, on which your Required Release is effective following the expiration of the maximum review/delivery period and all applicable revocation periods, but in no event shall such initial payment be made later than the last business day of such sixty (60)-day period on which the Required Release is so effective. The installment payments shall cease once you have received the full amount of your Cash Severance. The installment payments shall be treated as a series of separate payments for purposes of Section 409A. However, the amount of Cash Severance to which you may be entitled pursuant to the foregoing provisions of this Subsection 1(a) shall be subject to reduction in accordance with Section 4 in the event you breach your restrictive covenants under Section 4.

     (b) Options and Other Equity Awards. Notwithstanding any less favorable terms of any stock option or other equity award agreement or plan, any options to purchase shares of Broadcom’s common stock or any restricted stock units or other equity awards granted to you by Broadcom, whether before or after the date of this New Agreement, that are outstanding on your Date of Termination but not otherwise fully vested shall be subject to accelerated vesting in accordance with the following provisions:

          (i) On the date your timely executed and delivered Required Release becomes effective following the expiration of the maximum review/delivery period and any applicable revocation period (the “Release Condition”), you will receive twenty-four (24) months of service vesting credit under each of your outstanding stock options, restricted stock units and other equity awards.

          (ii) The portion of each of your outstanding stock options, restricted stock units and other equity awards that remains unvested after your satisfaction of the Release Condition will vest in a series of twenty-four (24) successive equal monthly installments over the twenty-four (24)-month period measured from your Date of Termination (the “Additional Monthly Vesting”), provided that during each successive month within that twenty-four (24)-month period (x) you must comply with all of your obligations under your Confidentiality and Invention Assignment Agreement with Broadcom that survive the termination of your employment with Broadcom and (y) you must comply with the restrictive covenants set forth in Section 4. In the event that you violate the Confidentiality and Invention Assignment Agreement or engage in any of the activities precluded by the restrictive covenants set forth in Section 4, you shall not be entitled to any Additional Monthly Vesting for and after the month in which such violation or activity (as the case may be) occurs.

     In addition, the period for exercising each option that accelerates in accordance with subparagraph (i) or (ii) above shall be extended from the limited post-termination period otherwise provided in the applicable stock option agreement until the earlier of (A) the end of the twenty-four (24)-month period measured from your Date of Termination or (if later) the end of the one-month period measured from each installment vesting date of that option in accordance herewith or (B) the applicable expiration date of the maximum ten (10)-year or shorter option term. Upon your satisfaction of the Release Condition, the limited post-termination exercise period for any other options

granted to you by Broadcom and outstanding on your Date of Termination shall also be extended in the same manner and to the same extent as your accelerated options

     The shares of Broadcom Class A common stock underlying any restricted stock unit award that vests on an accelerated or Additional Monthly Vesting basis in accordance with this Subsection 1(b) shall be issued as follows: The shares subject to that award that vest upon the satisfaction of the Release Condition shall be issued within the sixty (60) day period measured from the date of your Separation from Service, but in no event later than the next regularly-scheduled share issuance date for that restricted stock unit award (currently, the 5th day of February, May, August and November each year) following the date of your Separation from Service on which the Release Condition is satisfied, unless subject to further deferral pursuant to the provisions of Section 3 below the (“Initial Issuance Date”), and each remaining share subject to such restricted stock unit award shall be issued on the next regularly-scheduled share issuance date for that restricted stock unit award (currently, the 5th day of February, May, August and November each year) following the prescribed vesting date for that share in accordance with this Subsection 1(b), but in no event earlier than the Initial Issuance Date.

     (c) Lump Sum Benefit Payments. Provided you satisfy the Release Condition, the following special payments shall be made to you to provide you with a source of funding to cover a portion of the cost of any health care, life insurance and disability insurance coverage you obtain following your Date of Termination:

          (i) Provided you and your spouse and eligible dependents elect to continue medical care coverage under Broadcom’s group health care plans pursuant to the applicable COBRA provisions, Broadcom will make a lump sum cash payment (the “Lump Sum Health Care Payment”) to you in an amount equal to thirty-six (36) times the amount by which (i) the monthly cost payable by you, as measured as of your Date of Termination, to obtain COBRA coverage for yourself, your spouse and eligible dependents under Broadcom’s employee group health plan at the level in effect for each of you on such Date of Termination exceeds (ii) the monthly amount payable at such time by a similarly-situated executive whose employment with Broadcom has not terminated to obtain group health care coverage at the same level. Broadcom shall pay the Lump Sum Health Care Payment to you on the earlier of (A) the first business day of the first calendar month, within the sixty (60)-day period measured from the date of your Separation from Service, that is coincident with or next following the date on which your Required Release is effective following the expiration of the maximum review/delivery period and all applicable revocation periods or (B) the last business day of such sixty (60)-day period on which such Required Release is so effective. Notwithstanding the foregoing, the Lump Sum Health Care Payment shall be subject to the deferred payment provisions of Section 3 below, to the extent such payment exceeds the applicable dollar amount under section 402(g)(1) of the Code for the year in which your Separation from Service occurs. In addition, Broadcom cannot provide any assurances hereunder as to the maximum period for which you and your spouse and dependents may in fact be entitled to COBRA health care coverage under the Broadcom group health care plans, and it is

expected that such coverage will cease prior to the expiration of the thirty-six month period measured from your Date of Termination, except under certain limited circumstances.

          (ii) You shall also be entitled to an additional lump sum cash payment (the “Lump Sum Insurance Benefit Payment”) from Broadcom in an amount equal to twelve (12) times the amount by which (i) the monthly cost payable by you, as measured as of your Date of Termination, to obtain post-employment continued coverage under Broadcom’s employee group term life insurance and disability insurance plans at the level in effect for you on such Date of Termination exceeds (ii) the monthly amount payable at that time by a similarly-situated executive whose employment with Broadcom has not terminated to obtain similar coverage. Broadcom shall pay the Lump Sum Insurance Benefit Payment to you concurrently with the payment of the Lump Sum Health Care Benefit, provided, however, that the Lump Sum Insurance Benefit Payment shall be subject to the deferred payment provisions of Section 3 below, to the extent such payment, when added to the Lump Sum Health Care Payment, exceeds the applicable dollar amount under section 402(g)(1) of the Code for the year in which your Separation from Service occurs.

          Should you wish to obtain such actual post-employment continued coverage under Broadcom’s group term life insurance and disability insurance plans, Broadcom shall serve as the agent for transmitting your required monthly premium payments for such coverage to the applicable insurance companies. Broadcom shall serve such agency role solely to facilitate the payment of those monthly premiums to the applicable insurance companies and shall not be responsible or liable for any loss of coverage you may incur under such plans by reason of (i) your failure to make the required monthly premium payments to Broadcom on a timely basis so as to allow their transmittal to such insurance companies by the applicable due dates (including any applicable grace periods) or (ii) the failure of the insurance companies to make such post-employment coverage available under their applicable plans.

     (d) Additional Payments. Broadcom shall, to the extent applicable, pay you the following amounts, provided you satisfy the Release Condition:

          (i) any cash bonus that was not vested on your Date of Termination because a requirement of continued employment had not yet been satisfied by you, but with respect to which the applicable performance goal or goals had been fully attained as of your Date of Termination (for the avoidance of doubt, a bonus shall be payable under this clause (i) only to the extent that any performance criteria with respect to such bonus had been satisfied during the applicable performance period), and

          (ii) provided you were employed for the entire plan year immediately preceding your Date of Termination and discretionary bonuses are payable for that plan year to similarly-situated Broadcom executives whose employment has not terminated, any discretionary bonus the Compensation Committee may decide to award you for that plan year on the basis of your individual performance and contributions during that plan year.

     Any bonus payment to which you become entitled under clause (i) of this Subsection 1(c) shall be paid to you at the same time you are paid your first Cash Severance installment under Subsection 1(a), after taking into account any required deferral under Section 3 and provided further, that if such bonus is intended to qualify as “performance-based compensation” under Code Section 162(m), such payment shall also be subject to an appropriate present value discount reasonably reflecting the time value of money, in accordance with the Treasury Regulations under Code Section 162(m), to the extent such payment is in fact made earlier than the scheduled payment date for that bonus under the applicable Broadcom bonus plan or arrangement. Any bonus payment to which you may become entitled under clause (ii) of this Subsection 1(d) shall also be paid to you at the same time or (if later) the tenth business day following the date the Compensation Committee awards you such discretionary bonus, subject to any required deferral under Section 3.

     The amounts set forth Subsections 1(e) and (f) below shall be referred to collectively as the “Accrued Obligations” and shall not be subject to your delivery of the Required Release or your compliance with the restrictive covenants set forth in Section 4.

     (e) Accrued Salary, Vacation Pay, Expenses, Earned Bonuses and Deferred Compensation. Broadcom shall, upon your Date of Termination, pay you a lump sum amount equal to the sum of (i) any earned but unpaid base salary through the Date of Termination at the rate in effect during such period, (ii) your accrued vacation pay (if any), (iii) any unreimbursed business expenses incurred by you and (iv) any cash bonus that had been fully earned and vested (i.e., for which the applicable performance period and any service requirements for vesting had been fully completed) on or before the Date of Termination, but which had not been paid as of the Date of Termination (for the avoidance of doubt, any such bonus shall be payable only to the extent the applicable performance criteria had been satisfied during the applicable performance period and if such bonus is intended to qualify as “performance-based compensation” under Code Section 162(m), such payment shall be subject to an appropriate present value discount reasonably reflecting the time value of money, in accordance with the Treasury Regulations under Code Section 162(m), to the extent such payment is in fact made earlier than the scheduled payment date for that bonus under the applicable Broadcom bonus plan or arrangement.). However, any vested amounts deferred by you under one or more Broadcom non-qualified deferred compensation programs subject to Section 409A that remain unpaid on your Date of Termination shall be paid at such time and in such manner as set forth in each applicable plan or agreement governing the payment of those deferred amounts, subject, however, to the deferred payment provisions of Section 3 below.

     (f) Other Benefits. To the extent not theretofore paid or provided, Broadcom shall timely pay or provide to you any other amounts or benefits required to be paid or provided, or that you are eligible to receive, under any plan, program, policy, practice, contract or agreement of Broadcom and its affiliated companies, including (without limitation) any benefits payable to you under a plan, policy, practice, contract, agreement, etc., referred to in Section 15 of this Appendix II (all such other amounts and benefits being hereinafter referred to as “Other Benefits”), in accordance with the terms of such

plan, program, policy, practice, contract or agreement. However, the payment of such Other Benefits shall be subject to any applicable deferral period under Section 3 below to the extent those benefits constitute items of deferred compensation subject to Section 409A.

          Notwithstanding the foregoing provisions of this Subsection 1(f), in no event shall you be allowed to participate in the Broadcom Corporation 1998 Employee Stock Purchase Plan, as amended and restated, or the 401(k) Employee Savings Plan following your Date of Termination or to receive any substitute benefits hereunder in replacement of those particular benefits, but you shall be entitled to the full value of any benefits accrued under such plans prior to your Date of Termination.

     2. Required Release. You will not become eligible to receive any of the payments and benefits provided under Subsections 1(a), (b), (c) and (d) and Section 5 of this revised Appendix II unless you execute and deliver to Broadcom, within twenty one (21) days after your Date of Termination (or within forty-five (45) days after such Date of Termination, to the extent such longer period is required under applicable law), a general release in a form acceptable to Broadcom (the “Required Release”) that (i) releases Broadcom and its subsidiaries, officers, directors, employees, and agents from all claims you may have relating to your employment with Broadcom and the termination of that employment, other than claims relating to any benefits to which you become entitled under the Severance Program, and (ii) becomes effective in accordance with applicable law upon the expiration of any applicable revocation period.

     3. Delay in Payment for Certain Specified Employees. The following special provisions shall govern the commencement date of certain payments and benefits to which you may become entitled under the Severance Program:

          (a). Notwithstanding any provision in this New Agreement to the contrary other than Subsection 3(b) below, no payment or benefit under the Severance Program that constitutes an item of deferred compensation under Section 409A and becomes payable in connection with your termination of employment will be made to you prior to the earlier of (i) the first day of the seventh (7th) month following the date of your Separation from Service or (ii) the date of your death, if you are deemed to be a Specified Employee at the time of such Separation from Service and such delayed commencement is otherwise required to avoid a prohibited distribution under Section 409A(a)(2) of the Code. Any cash amounts to be so deferred shall immediately upon your Separation from Service be deposited by Broadcom into a grantor trust that satisfies the requirements of Revenue Procedure 92-64 and that will accordingly serve as the funding source for Broadcom to satisfy its obligations to you with respect to the heldback amounts upon the expiration of the required deferral period, provided, however, that the funds deposited into such trust shall at all times remain subject to the claims of Broadcom’s creditors and shall be maintained and located at all times in the United States. Upon the expiration of the applicable deferral period, all payments and benefits deferred pursuant to this Subsection 3(a) (whether they would have otherwise been payable in a single sum or in installments in the absence of such deferral) shall be paid or provided to you in a lump sum, either from the grantor trust or by Broadcom directly, on

the first day of the seventh (7th) month after the date of your Separation from Service or, if earlier, the first day of the month immediately following the date Broadcom receives proof of your death. Any remaining payments due under the Severance Program will be paid in accordance with the normal payment dates specified herein.

          (b). The portion of your Lump Sum Health Care Payment that is not in excess of the applicable dollar amount in effect under Section 402(g)(1)(B) of the Code for the calendar year in which your Separation from Service occurs shall not be subject to the Subsection 3(a) deferred payment requirement. If the Lump Sum Health Care Benefit does not exceed such dollar amount, then the deferred payment provisions of Subsection 3(a) shall not be applicable to the Lump Sum Insurance Benefit Payment to the extent the dollar amount of that payment, when added to the Lump Sum Health Care Payment, does not exceed the applicable dollar amount in effect under Section 402(g)(1)(B) of the Code for the calendar year in which your Separation from Service occurs.

          (c). It is the intent of the parties that the provisions of this New Agreement comply with all applicable requirements of Section 409A. Accordingly, to the extent there is any ambiguity as to whether one or more provisions of this New Agreement would otherwise contravene the applicable requirements or limitations of Section 409A, then those provisions shall be interpreted and applied in a manner that does not result in a violation of the applicable requirements or limitations of Section 409A and the applicable Treasury Regulations thereunder.

     4. Restrictive Covenants. You hereby acknowledge that your right and entitlement to the severance benefits specified in Subsections 1(a), (b)(ii) and Section 5 of this revised Appendix II are subject to your compliance with each of the following covenants during the three (3)-year period measured from your Date of Termination, and those enumerated severance benefits will immediately cease or be subject to reduction in accordance herewith should you breach any of the following covenants:

          (a) You shall not directly or indirectly encourage or solicit any employee, consultant or independent contractor to leave the employ or service of Broadcom (or any affiliated company) for any reason or interfere in any other manner with any employment or service relationships at the time existing between Broadcom (or any affiliated company) and its employees, consultants and independent contractors.

          (b) You shall not directly or indirectly solicit or otherwise induce any vendor, supplier, licensor, licensee or other business affiliate of Broadcom (or any affiliated company) to terminate its existing business relationship with Broadcom (or affiliated company) or interfere in any other manner with any existing business relationship between Broadcom (or any affiliated company) and any such vendor, supplier, licensor, licensee or other business affiliate.

          (c) You shall not, whether on your own or as an employee, consultant, partner, principal, agent, representative, equity holder or in any other capacity, directly or indirectly render, anywhere in the United States, services of any kind or provide any advice or assistance to any business, enterprise or other entity that is engaged in any line of business that competes with one or more of the lines of business that were conducted by Broadcom during the

Term of your employment or that are first conducted after your Date of Termination but which you were aware were under serious consideration by Broadcom prior to your Date of Termination, except that you make a passive investment representing an interest of less than one percent (1%) of an outstanding class of publicly-traded securities of any corporation or other enterprise.

          (d) You shall not, directly or indirectly, make any adverse, derogatory or disparaging statements, whether orally or in writing, to any person or entity regarding (i) Broadcom, any members of the Board of Directors or any officers, members of management or shareholders of Broadcom or (ii) any practices, procedures or business operations of Broadcom (or any affiliated company).

          Should you breach any of the restrictive covenants set forth in this Section 4, then you shall immediately cease to be entitled to any Gross-Up Payment under Section 5 below or any Cash Severance Payments pursuant to Subsection 1(a) in excess of the greater of (i) one (1) times the sum of (A) your annual rate of base salary (using your then current rate or, if you terminate your employment for Good Reason pursuant to Subsection 9(b) of this Appendix II due to an excessive reduction in your base salary, then your rate of base salary immediately before such reduction) and (B) the average of your actual annual bonuses for the three calendar years (or such fewer number of calendar years of employment with Broadcom) immediately preceding the calendar year in which such termination of employment occurs (which minimum amount represents partial consideration for your satisfaction of the Release Consideration) or (ii) the actual Cash Severance Payments you have received through the date of such breach. In addition, all Additional Monthly Vesting of any stock options, restricted stock units, other equity awards or unvested share issuances outstanding at the time of such breach shall cease as of the month in which such breach occurs, and no further Additional Monthly Vesting shall occur thereafter. Broadcom shall also be entitled to recover at law any monetary damages for any additional economic loss caused by your breach and may, to the maximum extent allowable under applicable law, seek equitable relief in the form of an injunction precluding you from continuing such breach.

     5. Tax Gross-Up Payment.

          A. In the event that (i) any payments or benefits to which you become entitled in accordance with the provisions of the New Agreement and this revised Appendix II or any other agreement with Broadcom constitute a parachute payment under Section 280G of the Code (collectively, the “Parachute Payment”) subject to the excise tax imposed under Section 4999 of the Code or any interest or penalties related to such excise tax (with such excise tax and related interest and penalties to be collectively referred to as the “Excise Tax”) and (ii) it is determined by an independent registered public accounting firm selected by Broadcom from among the largest four accounting firms in the United States (the “Accounting Firm”) that the Present Value (measured as of effective date of the Change in Control) of your aggregate Parachute Payment exceeds one hundred twenty percent (120%) of your Permissible Parachute Amount, then you will be entitled to receive from Broadcom an additional payment (the “Gross-Up Payment”) in a dollar amount such that after your payment of all taxes (including any interest or penalties imposed with respect to such taxes), including any Excise Tax imposed upon the Gross-Up Payment, you retain a net amount equal to the Excise Tax imposed upon your aggregate Parachute Payment. Notwithstanding the foregoing, you shall not be entitled to any Gross-Up Payment unless there is compliance with each of the Severance Benefit Requirements set forth above.

          For purposes of determining your eligibility for such Gross-Up Payment, the following definitions will be in effect:

          “Present Value” means the value, determined as of the date of the Change in Control, of each payment or benefit in the nature of compensation to which you become entitled in connection with the Change in Control or your subsequent termination of employment with Broadcom that constitutes a Parachute Payment. The Present Value of each such payment or benefit shall be determined in accordance with the provisions of Code Section 280G(d)(4), utilizing a discount rate equal to one hundred twenty percent (120%) of the applicable Federal rate in effect at the time of such determination, compounded semi-annually to the effective date of the Change in Control.

          “Permissible Parachute Amount” means a dollar amount equal to the 2.99 times the average of your W-2 wages from Broadcom for the five (5) calendar years (or such fewer number of calendar years) completed immediately prior to the calendar year in which the Change in Control is effected.

          Should the aggregate Present Value (measured as of the Change in Control) of your aggregate Parachute Payment not exceed one hundred twenty percent (120%) of your Permissible Parachute Amount, then no Gross-Up Payment will be made to you, and your payments and benefits under this New Agreement shall instead be subject to reduction in accordance with the benefit limitation provisions of Section 6.

          B. All determinations as to whether any of the payments or benefits to which you become entitled in accordance with the provisions of the New Agreement and this revised Appendix II or any other agreement with Broadcom constitute a Parachute Payment, whether a Gross-Up Payment is required with respect to any Parachute Payment, the amount of such Gross-Up Payment, and any other amounts relevant to the calculation of such Gross-Up Payment, will be made by the Accounting Firm. Such Accounting Firm will make the applicable

determinations (the “Gross-Up Determination”), together with detailed supporting calculations regarding the amount of the Excise Tax, any required Gross-Up Payment and any other relevant matter, within thirty (30) days after the date of your Separation from Service. In making the Gross-Up Determination, the Accounting Firm shall make a reasonable determination of the value of the restrictive covenants to which you will be subject under Section 4, and the amount of your potential Parachute Payment shall accordingly be reduced by the value of those restrictive covenants to the extent consistent with Code Section 280G and the Treasury Regulations thereunder. The Gross-Up Determination made by the Accounting Firm will be binding upon both you and Broadcom. The Gross-Up Payment (if any) determined on the basis of the Gross-Up Determination shall be paid to you or on your behalf within ten (10) business days after the completion of such Determination or (if later) at the time the related Excise Tax is remitted to the appropriate tax authorities.

          C. In the event that your actual Excise Tax liability is determined by a Final Determination to be greater than the Excise Tax liability taken into account for purposes of any Gross-Up Payment or Payments initially made to you pursuant to the provisions of Subsection 5.B, then within thirty (30) days following that Final Determination, you shall notify Broadcom of such determination, and the Accounting Firm shall, within thirty (30) days thereafter, make a new Excise Tax calculation based upon that Final Determination and provide both you and Broadcom with the supporting calculations for any supplemental Gross-Up Payment attributable to that excess Excise Tax liability. Broadcom shall make the supplemental Gross-Up payment to you within ten (10) business days following the completion of the applicable calculations or (if later) at the time such excess tax liability is remitted to the appropriate tax authorities. In the event that your actual Excise Tax liability is determined by a Final Determination to be less than the Excise Tax liability taken into account for purposes of any Gross-Up Payment initially made to you pursuant to the provisions of Subsection 5.B, then you shall refund to Broadcom, promptly upon receipt (but in no event later than ten (10) business days after such receipt), any federal or state tax refund attributable to the Excise Tax overpayment. For purposes of this Subsection 5.C, a “Final Determination” means an audit adjustment by the Internal Revenue Service that is either (i) agreed to by both you and Broadcom or (ii) sustained by a court of competent jurisdiction in a decision with which both you and Broadcom concur or with respect to which the period within which an appeal may be filed has lapsed without a notice of appeal being filed.

          D. Should the Accounting Firm determine that any Gross-Up Payment made to you was in fact more than the amount actually required to be paid to you in accordance with the provisions of Subsection 5.B, then you will, at the direction and expense of Broadcom, take such steps as are reasonably necessary (including the filing of returns and claims for refund), follow reasonable instructions from, and procedures established by, Broadcom, and otherwise reasonably cooperate with Broadcom to correct such overpayment. Furthermore, should Broadcom decide to contest any assessment by the Internal Revenue Service of an Excise Tax on one or more payments or benefits provided you under the New Agreement or this revised Appendix II or otherwise, you will comply with all reasonable actions requested by Broadcom in connection with such proceedings, but shall not be required to incur any out-of-pocket costs in so doing.

          E. Notwithstanding anything to the contrary in the foregoing, any Gross-Up Payments due you under this Section 5 shall be subject to the hold-back provisions of Section 3. In addition, no Gross-Up Payment shall be made later than the end of the calendar year following the calendar year in which the related taxes are remitted to the appropriate tax authorities or such other specified time or schedule that may be permitted under Section 409A of the Code. To the extent you become entitled to any reimbursement of expenses incurred at the direction of Broadcom in connection with any tax audit or litigation addressing the existence or amount of the Excise Tax, such reimbursement shall be paid to you no later than the later of (i) the close of the calendar year in which the Excise Tax that is the subject of such audit or litigation is paid by you or (ii) the end of the sixty (60)-day period measured from such payment date. If no Excise Tax liability is found to be due as a result of such audit or litigation, the reimbursement shall be paid to you no later than the later of (i) the close of the calendar year in which the audit is completed or there is a final and non-appealable settlement or other resolution of the litigation or (ii) the end of the sixty (60)-day period measured from the date the audit is completed or the date the litigation is so settled or resolved.

     6. Benefit Limitation. The provisions of this Section 6 shall be applicable in the event (i) any payments or benefits to which you become entitled in accordance with the provisions of the New Agreement and this revised Appendix II or any other agreement with Broadcom would otherwise constitute a Parachute Payment that is subject to the Excise Tax and (ii) it is determined by the Accounting Firm that the Present Value (measured as of effective date of the Change in Control) of your aggregate Parachute Payment does not exceed one hundred twenty percent (120%) of your Permissible Parachute Amount or you are not otherwise entitled to the Gross-Up Payment by reason of your failure to comply with your restrictive covenants under Section 4 or any other of your Severance Benefit Requirements.

          In such event, those payments and benefits will be subject to reduction to the extent necessary to assure that you receive only the greater of (i) your Permissible Parachute Amount or (ii) the amount which yields you the greatest after-tax amount of benefits after taking into account any excise tax imposed under Section 4999 of the Code on the payments and benefits provided to you under the New Agreement and this revised Appendix II (or on any other benefits to which you may be entitled in connection with a change in control or ownership of Broadcom or the subsequent termination of your employment with Broadcom). To the extent any such reduction is required, the dollar amount of your Cash Severance under Subsection 1(a) of this revised Appendix II will be reduced first, with such reduction to be effected pro-rata as to each payment, then the dollar amount of your Lump Sum Health Care and Insurance Benefit Payments shall each be reduced pro-rata, next the number of options or other equity awards that are to vest on an accelerated basis pursuant to Subsection 1(b) of this revised Appendix II shall be reduced (based on the value of the parachute payment resulting from such acceleration) in the same chronological order in which awarded, and finally your remaining benefits will be reduced in a manner that will not result in any impermissible deferral or acceleration of benefits under Section 409A.

          Notwithstanding the foregoing, in determining whether the benefit limitation of this Section 6 is exceeded, the Accounting Firm shall make a reasonable determination of the value of the restrictive covenants to which you will be subject under Section 4 of this revised Appendix II, and the amount of your potential Parachute Payment shall accordingly be reduced

by the value of those restrictive covenants to the extent consistent with Code Section 280G and the Treasury Regulations thereunder.

     7. Other Terminations. Notwithstanding the provisions of Section 1 of this revised Appendix II, if your employment is terminated by reason of your death or by Broadcom for Cause or by reason of your Disability, or you terminate your employment without Good Reason, you shall not be entitled to participate in the Severance Program, and your participation in the Severance Program shall terminate without further obligations to you or your legal representatives under the Severance Program, provided, however, that Broadcom shall timely pay the Accrued Obligations and shall timely pay or provide the Other Benefits to you, your legal representative or your designated beneficiaries, as the case may be. However, in the event your employment is terminated by reason of your death or Disability, then

     (i) Broadcom shall also pay the bonuses described in Subsection 1(d) above, if any, to you or your legal representative, with the payment under paragraph (i) of such subsection to be made within sixty (60) days after the date of your Separation from Service due to death or Disability, subject to any required holdback under Section 3 and, provided further that if such bonus is intended to qualify as “performance-based compensation” under Code Section 162(m), such payment shall be subject to an appropriate present value discount reasonably reflecting the time value of money, in accordance with the Treasury Regulations under Code Section 162(m), to the extent such payment is in fact made earlier than the scheduled payment date for that bonus under the applicable Broadcom bonus plan or arrangement, and with the payment of any bonus due you under paragraph (ii) of that subsection to be made at the same time as the foregoing payment or (if later) the tenth business day following the date the Compensation Committee awards you such discretionary bonus, subject to any required deferral under Section 3; and

     (ii) notwithstanding any less favorable terms in any stock option or other equity award agreement or plan or this Severance Program or the Employment Agreement, any unvested portion of any stock options, restricted stock units or other equity awards granted to you by Broadcom, whether before or after the date of this New Agreement, shall immediately vest in full on your Date of Termination and remain exercisable by you or your legal representative for 12 months after the Date of Termination.

     The shares of Broadcom Class A common stock subject to any restricted stock unit award that vests on an accelerated basis in accordance with the foregoing shall be issued within the sixty (60) day period measured from the date of your Separation from Service due to your death or Disability, but in no event later than the next regularly-scheduled share issuance date for that restricted stock unit award date (currently, the 5th day of February, May, August and November each year) following the date of your Separation from Service, unless subject to further deferral pursuant to the provisions of Section 3 above.

     8. Cause. Broadcom may terminate your employment with or without Cause as defined in this Section 8. For purposes of the Employment Agreement and the Severance Program, “Cause” shall mean the reasonable and good faith determination by a majority of Broadcom’s Board of Directors (the “Board”) that any of the following events or contingencies exists or has occurred:

     (a) You materially breached a fiduciary duty to Broadcom, materially breached a material term of the Confidentiality and Invention Assignment Agreement between you and Broadcom, or materially breached any material term or policy set forth or described in Broadcom’s Code of Ethics and Corporate Conduct;

     (b) You are convicted of a felony that involves fraud, dishonesty, theft, embezzlement and/or an act of violence or moral turpitude, or plead guilty or no contest (or a similar plea) to any such felony;

     (c) You engage in any act, or there is any omission on your part, that constitutes fraud, material negligence or material misconduct in connection with your employment by Broadcom, including (but not limited to) a material violation of applicable material state or federal securities laws. Notwithstanding the foregoing, an isolated or occasional failure to file or late filing of a report required under Section 16 of the Exchange Act shall not be deemed a material violation for purposes of this Subsection 8(c). Furthermore, with respect to filing reports or certifications you are required to provide under the Exchange Act, with respect to a transaction’s compliance with the requirements of Rule 144 under the Securities Act of 1933, as amended or with respect to the implementation of your 10b5-1 Plan, you shall not have committed a material violation for purposes of this Subsection 8(c) if the violation occurred because you relied in good faith on a certification or certifications provided by Broadcom or an authorized employee or agent of Broadcom, unless you knew or should have known after reasonable diligence that such certification was inaccurate, or upon the processes or actions of the securities brokerage firm handling your transactions in Broadcom equities provided that you have used a nationally recognized securities brokerage firm with substantial prior experience in and established regular procedures for handling option and equity transactions by executive officers of public companies in the United States; or

     (d) You willfully and knowingly participate in the preparation or release of false or materially misleading financial statements relating to Broadcom’s operations and financial condition or you willfully and knowingly submit any false or erroneous certification required of you under the Sarbanes-Oxley Act of 2002 or any securities exchange on which             shares of Broadcom’s Class A common stock are at the time listed for trading.

     The foregoing shall constitute an exclusive list of the events or contingencies that may constitute Cause under the Employment Agreement and this revised Appendix II.

     No termination that is based exclusively upon your commission or alleged commission of act(s) or omission(s) that are asserted to constitute material negligence shall constitute Cause hereunder unless you have been afforded notice of the alleged acts or omissions and have failed to cure such acts or omissions within thirty (30) days after receipt of such notice.

     If, following the receipt of a Notice of Termination stating that your termination is for Cause, you believe that Cause does not exist, you may, by written notice delivered to the Board within three business (3) days after receipt of such Notice of Termination, request that your Date of Termination be delayed to permit you to appeal the Board’s determination that Cause for such

termination existed. If you so request, you will be placed on administrative leave for a period determined by the Board (not to exceed 30 days), during which you will be afforded an opportunity to request that the Board reconsider its decision concerning your termination. If the Board or an appropriate committee thereof has not previously provided you with an opportunity to be heard in person concerning the reasons for termination stated in the Notice of Termination, the Board will endeavor in good faith to provide you with such an opportunity during such period of administrative leave. It is understood and agreed that any change in your employment status that occurs in connection with or as a result of such an administrative leave shall not constitute Good Reason. The Board may, as a result of such a request for reconsideration, reinstate your employment, revise the original Notice of Termination, or affirm the original Notice of Termination. If the Board affirms the original Notice of Termination or the period of administrative leave ends before the Board takes action, the Date of Termination shall be the date specified in the original Notice of Termination. If the Board reinstates your employment or revises the original Notice of Termination, then the original Notice of Termination shall be void and neither its delivery nor its contents shall be deemed to constitute Good Reason.

     9. Good Reason. You may terminate your employment with or without Good Reason as defined in this Section 9. For purposes of the Employment Agreement and the Severance Program, “Good Reason” shall mean:

     (a) except as you may otherwise agree in writing and except as a result of an administrative leave and the related procedure described in the definition of Cause above, a change in your position (including status, offices, titles and reporting requirements) with Broadcom that materially reduces your authority, duties or responsibilities as in effect on the day you commenced employment, or any other action by Broadcom that results in a material diminution in such position, authority, duties or responsibilities, excluding for this purpose an isolated, insubstantial or inadvertent action that is remedied by Broadcom reasonably promptly after Broadcom receives your notice thereof; however, for purposes of this Subsection 9(a), it will be deemed to be a material reduction or diminution in your position or duties if (i) you are not at all times Broadcom’s Chief Executive Officer and a member of the Board of Directors of Broadcom (or any successor entity), or in lieu thereof if Broadcom (or its successor) has any parent entities, then you are not at all times the Chief Executive Officer and a member of the board of directors of the highest such parent entity, (ii) Broadcom (acting through the Board) or any individual who has the right to vote securities representing more than 10% of the voting power of all of Broadcom’s common shares publicly and materially disparages you through any oral or written communications to any third party (provided, however, that in no event shall non-public communications by or between you and Broadcom or any member of the Board, such as performance reviews, be considered to constitute such public and material disparagement), or (iii) Broadcom hires, appoints or promotes any person to an executive officer position at Broadcom without your prior consent (which you shall not unreasonably withhold);

     (b) any reduction in your base salary, as the same may be increased from time-to-time, provided, however, that a reduction or series of reductions in your base salary (not exceeding 15% in the aggregate) that is part of a broad-based reduction in base salaries for management employees and pursuant to which your base salary is not

reduced by a greater percentage than the reductions applicable to other management employees shall not constitute Good Reason

     (c) any action by Broadcom (including the elimination of benefit plans without providing substitutes therefor or the reduction of your benefit thereunder) that would materially diminish the aggregate value of your bonuses and other cash incentive awards and fringe benefits, including executive benefits and perquisites, from the levels in effect on the date of the New Agreement, by more than fifteen percent (15%) in the aggregate, provided, however, that (i) a reduction in your bonuses, cash awards or benefits that is part of a broad-based reduction in corresponding bonuses, awards or benefits for management employees and pursuant to which your bonuses, awards or benefits are not reduced by a greater percentage than the reductions applicable to other management employees and (ii) a reduction in your bonuses and other cash incentive awards occurring as a result of your failure or Broadcom’s failure to satisfy performance criteria applicable to such bonuses or awards shall not constitute Good Reason;

     (d) Broadcom’s requiring you to be based at any office or business location that increases the distance from your home to such office or location by more than fifty (50) miles from the distance in effect as of the date that such requirement is imposed;

     (e) any purported termination by Broadcom of your employment other than pursuant to a Notice of Termination (for avoidance of doubt, the delivery or contents of a Notice of Termination that is revised or voided under the procedure provided in the definition of Cause above shall not constitute Good Reason); or

     (f) any failure by Broadcom (or any successor) to comply with and satisfy Section 17 of this revised Appendix II after receipt of written notice from you of such failure and a reasonable cure period of not less than thirty (30) days.

     The foregoing shall constitute an exclusive list of the events or contingencies that may constitute Good Reason under your Employment Agreement and this revised Appendix II.

     Notwithstanding the above, an isolated or inadvertent action or inaction by Broadcom that causes Broadcom to fail to comply with Subsections 9(b) or 9(c) and that is cured within ten (10) days of your notifying Broadcom of such action or inaction shall not constitute Good Reason. Furthermore, no act, occurrence or condition set forth in this Section 9 shall constitute Good Reason if you consent in writing to such act, occurrence or condition, whether such consent is delivered before or after the act, occurrence or condition comes to pass.

     10. Death. Your employment shall terminate automatically upon your death.

     11. Disability. If your Disability occurs while you are employed by Broadcom and no reasonable accommodation is available to permit you to continue to perform the essential duties and responsibilities of your position, Broadcom may give you written notice of its intention to terminate your employment. In such event, your employment with Broadcom shall terminate effective on the 30th day after you receive such notice (the “Disability Effective Date”), provided you shall not have returned to performing your duties within thirty (30) days after such receipt. For purposes of the Employment Agreement and the Severance Program, “Disability”

shall mean your absence from and inability to perform your duties with Broadcom on a full-time basis for one hundred eighty (180) consecutive business days as a result of incapacity due to mental or physical illness that is both (i) determined to be total and permanent by two (2) physicians selected by Broadcom or its insurers and acceptable to you or your legal representative, and (ii) to the extent you are eligible to participate in Broadcom’s long-term disability plan, entitles you to the payment of long-term disability benefits from Broadcom’s long-term disability plan commencing immediately upon the Disability Effective Date.

     12. Notice of Termination. For purposes of the Severance Program, a “Notice of Termination” means a written notice that (i) indicates the specific termination provision relied upon for the termination of your employment, (ii) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of your employment under the provision so indicated, and (iii) if the Date of Termination (as defined below) is other than the date of receipt of such notice, specifies the termination date (which date shall be not more than thirty (30) days after the giving of such notice). The basis for termination set forth in any Notice of Termination shall constitute the exclusive set of facts and circumstances upon which the party may rely to attempt to demonstrate that Cause or Good Reason (as the case may be) for such termination existed.

     13. Date of Termination. “Date of Termination” means (i) except as set forth in the definition of Cause, if your employment is terminated by Broadcom or by you for any reason other than death or Disability, the date of receipt of the Notice of Termination or a later date (within the limit set forth in the definition of Notice of Termination) specified therein, as the case may be, and (ii) if your employment is terminated by reason of death or Disability, the Date of Termination shall be the date of your death or the Disability Effective Date, as the case may be.

     14. Definitions. For purposes of the Severance Program in effect under this revised Appendix II, the following additional definitions shall be in effect:

          “Code” means the Internal Revenue Code of 1986, as amended from time to time.

          “Separation from Service” means the cessation of your Employee status and shall be deemed to occur at such time as the level of the bona fide services you are to perform in Employee status (or as a consultant or other independent contractor) permanently decreases to a level that is not more than twenty percent (20%) of the average level of services you rendered in Employee status during the immediately preceding thirty-six (36) months (or such shorter period for which you may have rendered such service). Any such determination as to Separation from Service, however, shall be made in accordance with the applicable standards of the Treasury Regulations issued under Section 409A. In addition to the foregoing, a Separation from Service will not be deemed to have occurred while you are on a sick leave or other bona fide leave of absence if the period of such leave does not exceed six (6) months or any longer period for which you are provided with a right to reemployment with Broadcom by either statute or contract, provided, however, that in the event of a leave of absence due to any medically determinable physical or mental impairment that can be expected to result in death or to last for a continuous period of not less than six (6) months and that causes you to be unable to perform your duties as an Employee, no Separation from Service shall be deemed to occur during the first twenty-nine (29) months of such leave. If the period of leave exceeds six (6) months (or twenty-nine (29)

months in the event of disability as indicated above) and you are not provided with a right to reemployment by either statute or contract, then you will be deemed to have Separated from Service on the first day immediately following the expiration of the applicable six (6)-month or twenty-nine (29)-month period.

     For purposes of determining whether a Separation from Service has occurred, you will be deemed to continue in “Employee” status for so long as you remain in the employ of one or more members of the Employer Group, subject to the control and direction of the employer entity as to both the work to be performed and the manner and method of performance.

     “Employer Group” means Broadcom and any other corporation or business controlled by, controlling or under common control with, Broadcom, as determined in accordance with Sections 414(b) and (c) of the Code and the Treasury Regulations thereunder, except that in applying Sections 1563(1), (2) and (3) of the Code for purposes of determining the controlled group of corporations under Section 414(b), the phrase “at least 50 percent” shall be used instead of “at least 80 percent” each place the latter phrase appears in such sections, and in applying Section 1.414(c)-2 of the Treasury Regulations for purposes of determining trades or businesses that are under common control for purposes of Section 414(c), the phrase “at least 50 percent” shall be used instead of “at least 80 percent” each place the latter phrase appears in Section 1.4.14(c)-2 of the Treasury Regulations.

     “Specified Employee” means a “key employee” (within the meaning of that term under Code Section 416(i)). Accordingly, you will be deemed to be a Specified Employee if you are at any time during the twelve (12)-month period ending on the last day of any calendar year:

          (i) an officer of Broadcom whose annual compensation from Broadcom and any other members of the Employer Group is in the aggregate greater than the compensation limit in Section 416(i)(1)(A)(i) of the Code, provided that no more than fifty (50) officers of Broadcom shall be determined to be Specified Employees as of the relevant determination date;

          (ii) a five percent (5%) owner of Broadcom or any other member of the Employer Group; or

          (iii) a one percent (1%) owner of Broadcom or any other member of the Employer Group whose annual compensation from Broadcom and any other members of the Employer Group is in the aggregate more than $150,000.

     The Specified Employees shall be determined as of the last day of each calendar year. If you are determined to be a Specified Employee on any such date, you will be considered a Specified Employee for purposes of the Severance Program during the period beginning on the April 1 of the following year and ending on the March 31 of the next year thereafter.

     For purposes of determining an officer’s compensation when identifying Specified Employees, compensation is defined in accordance with Treas. Reg. §1.415(c)-2(a), without applying any safe harbor, special timing or other special rules described in Treas. Reg. §§ 1.415(c)-2(d), 2(e) and 2(g).

     15. Non-exclusivity of Rights. Nothing in the Severance Program shall prevent or limit your continuing or future participation in any plan, program, policy or practice provided by Broadcom or any of its affiliated companies and for which you may qualify, nor, subject to Subsection 1(b), shall anything herein limit or otherwise affect such rights as you may have under any contract or agreement with Broadcom or any of its affiliated companies. Amounts that are vested benefits or which you are otherwise entitled to receive under any plan, policy, practice or program of or any contract or agreement with Broadcom or any of its affiliated companies at or subsequent to the Date of Termination shall be payable in accordance with such plan, policy, practice or program or contract or agreement, except as explicitly modified by this revised Appendix II.

     16. Full Settlement. Except as specifically set forth in this revised Appendix II or the accompanying Employment Agreement, Broadcom’s obligation to make the payments provided for in the Severance Program and otherwise to perform its obligations hereunder shall not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action which Broadcom may have against you or others, except only for any advances made to you or for taxes that Broadcom is required to withhold by law. In no event shall you be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to you under any of the provisions of the Severance Program, and such amounts shall not be reduced whether or not you obtain other employment.

     17. Successors.

     (a) Any benefits payable under the Severance Program are personal to you and shall not be assignable by you otherwise than by will or the laws of descent and distribution. The benefits under the Severance Program shall inure to the benefit of and be enforceable by your legal representatives.

     (b) Any rights and obligations under the Severance Program shall inure to the benefit of and be binding upon Broadcom and its successors and assigns.

     (c) Broadcom will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of Broadcom to expressly assume and agree in writing to perform its obligations under the Employment Agreement and the Severance Program in the same manner and to the same extent that Broadcom would be required to perform those obligations it if no such succession had taken place. As used in the Severance Program, “Broadcom” shall include any successor to all or substantially all of its business and/or assets, as aforesaid, which assumes and agrees to perform the obligations created by the Severance Program by operation of law or otherwise.

     18. Severability. If any provision of this revised Appendix II as applied to any party or to any circumstance should be adjudged by a court of competent jurisdiction or determined by an arbitrator to be void or unenforceable for any reason, the invalidity of that provision shall in no way affect (to the maximum extent permissible by law) the application of such provision under circumstances different from those adjudicated by the court or determined by the arbitrator, the application of any other provision of this revised Appendix II, or the enforceability or invalidity of this revised Appendix II as a whole. Should any provision of this revised Appendix II become or be deemed invalid, illegal or unenforceable in any jurisdiction by reason of the scope, extent or duration of its coverage, then such provision shall be deemed amended to the extent necessary to conform to applicable law so as to be valid and enforceable or, if such provision cannot be so amended without materially altering the intention of the parties, then such provision will be stricken, and the remainder of this revised Appendix II shall continue in full force and effect.

     19. Withholding Taxes. Broadcom shall withhold from any amounts payable under the Severance Program all Federal, state, local or foreign taxes required to be withheld pursuant to any applicable law or regulation.

     To acknowledge your participation in the Severance Program pursuant to the New Agreement revising the terms and provisions of attached Appendix II to your Employment Agreement and your understanding of those terms and provisions, please sign, date and return the enclosed copy of this New Agreement.

ACCEPTANCE

I hereby accept all of the terms and conditions of the New Agreement, including the revised Appendix II thereto, and agree to be bound by all those terms and conditions.
