1.1 Successor Plan. The Plan is the successor plan to the Gilead Sciences, Inc. Deferred Compensation Plan, effective January 1, 2002, as amended (the “Prior Plan”). Effective as of December 31, 2004, the Prior Plan was frozen, and no new contributions were permitted to be made to it; provided, however, that any deferrals made under the Prior Plan before January 1, 2005 will continue to be governed by the terms and conditions of the Prior Plan as in effect on December 31, 2004. Any deferrals made under the Prior Plan after December 31, 2004 will be deemed to have been made under this Plan, and all such deferrals will accordingly be governed by the terms and conditions of this Plan, as it may be amended from time to time.

1.2 Restatement. The purpose of this October 22, 2007 restatement, as subsequently amended effective January 1, 2008, is to evidence the documentary compliance of the Plan, effective retroactive to January 1, 2005, with the applicable requirements of Section 409A of the Internal Revenue Code, the Treasury Regulations issued under Section 409A and the interim guidance provided by the Internal Revenue and the Treasury Department prior to the publication of the final Section 409A Regulations.

2.1 Plan Purpose. The Employer maintains the Plan, a deferred compensation plan, for the benefit of (i) a select group of management and other highly compensated employees of the Employer and (ii) the non-employee members of the Employer’s Board of Directors. Each other Participating Employer will also maintain the Plan as a deferred compensation plan for the benefit of a select group of its management personnel and other highly compensated employees. The Participating Employers intend that the existence of the Trust will not alter the characterization of the Plan as “unfunded” for purposes of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and will not be deemed to provide income to Participants under the Plan prior to the actual payment of their vested accrued benefits hereunder. The Participating Employers intend that the Plan comply with the requirements of Section 409A of the Code and the regulations promulgated thereunder.

3.1 Effective Date. The effective date of the Plan is January 1, 2005, except as otherwise noted herein.

5.1 Eligibility. The Administrator (acting through an authorized committee of one or more officers or other senior executives) shall have absolute discretion in selecting the Eligible Employees who are to participate in the Plan for each Plan Year. An Eligible Employee selected for participation for any Plan Year must, in order to participate in the Plan for that year, file a timely Deferral Election in accordance with the requirements of Section 6.1. An Eligible Employee who is first selected for participation in the Plan after the start of a Plan Year and who has not otherwise been eligible for participation in any other non-qualified elective account balance plan subject to Code Section 409A and maintained by one or more Affiliated Companies may file a Deferral Election for that Plan Year in accordance with the applicable requirements of Section 6.1. Until such time as the Administrator implements a new policy, any selection of new Participants after the start of the Plan Year will be limited to the first business day of April of that Plan Year. Individuals who are selected for participation in the Plan, whether before or after

6

the start of the Plan Year, shall be promptly notified by their Participating Employer of their eligibility to participate in the Plan. Eligible Directors shall automatically be eligible to participate in the Plan during their period of service in such capacity, and their Deferral Elections shall be subject to the same requirements set forth above for Employee Participants.

5.2 Continuation of Participation. Every Eligible Employee who becomes a Participant may continue to file Deferral Elections under the Plan for one or more subsequent Plan Years until the earliest of (i) his or her exclusion from the Plan upon written notice from the Administrator, (ii) his or her cessation of Eligible Employee status or (iii) the termination of the Plan. The Administrator shall have complete discretion to exclude one or more Eligible Employees from Participant status for one or more Plan Years as the Administrator deems appropriate, including the entire period the Participant continues in Eligible Employee status following such exclusion. However, no such exclusion authorized by the Administrator shall become effective until the first day of the first Plan Year coincident with or next following the date of the Administrator’s determination to exclude the individual from such participation. If any Eligible Employee is excluded from Participant status for one or more Plan Years, then such individual shall not be entitled to defer any part of his or her Compensation for those Plan Years.

5.3 Resumption of Participation Following Separation from Service. If a Participant ceases to be an Eligible Employee or an Eligible Director due to a Separation from Service and thereafter returns to service with the Employer, such individual will again become a Participant as of the first day of the first Plan Year coincident with or next following the date on which he or she resumes Eligible Employee or Eligible Director status, provided such individual files a timely a Deferral Election pursuant to Section 6.1 with respect to that Plan Year. However, a Participant who returns to Eligible Employee or Eligible Director status after a Separation from Service of more than twenty-four (24) months during which he or she was not eligible to defer any Compensation under this Plan or any other any other non-qualified elective account balance plan subject to Code Section 409A and maintained by one or more Affiliated Companies shall, following resumption of such service, be permitted to make a Deferral Election under Section 6.1 in accordance with the requirements applicable to a newly-selected Participant. Notwithstanding the foregoing provisions of this Section 5.3, no returning Eligible Employee shall be eligible to participate in the Plan if the Administrator determines to exclude such individual from participation on or before his or her resumption of service.

5.4 Cessation or Resumption of Participation Following a Change in Status. If any Participant continues in the service of the Employer Group but ceases to be an Eligible Employee or Eligible Director, the individual will continue to be a Participant until the entire amount of his or her Account balance is distributed. However, the individual will not be entitled to make any Deferral Elections with respect to Compensation earned for the period that he is not an Eligible Employee or Eligible Director. In the event that the individual subsequently resumes Eligible Employee or Eligible Director status, he or she will again become a Participant as of the first day the first Plan Year coincident with or next following the date of his or her resumption of Eligible Employee or Eligible Director status, provided such individual files a timely a Deferral Election pursuant to Section 6.1 with respect to that Plan Year. However, an Eligible Employee shall not be eligible to participate in the Plan upon his or her resumption of Eligible Employee status if the Administrator determines to exclude such individual from participation on or before resumption of such status.

6.1 Deferral Elections for Employee Participants. Each Eligible Employee selected for participation shall have the right to file a Deferral Election with respect to the Salary and/or Bonus to be earned by such Participant for service as an Eligible Employee during the Plan Year for which the Deferral Election is made. Each Deferral Election must be made by a written or electronic notice filed with the Administrator or its designate in which the Participant shall indicate the percentage of Salary and/or Bonus to be deferred in accordance with the applicable percentage limitations set forth in Section 6.5. The notice must be filed on or before the expiration date of the enrollment period designated by the Administrator for the Plan Year for which the Deferral Election is to be effective, but in no event shall the Administrator allow any Deferral Election to be filed later than the last day of the calendar year immediately preceding the start of the Plan Year for which the Salary and/or Bonus subject to that election are to be earned. However, the following special rules shall be in effect for Deferral Elections:

(A) The Administrator may allow a Deferral Election with respect to a Bonus which qualifies as performance-based compensation in accordance with the standards and requirements set forth in Section 1.409A-1(e) of the Treasury Regulations to be made by a Participant after the start of the Plan Year (or other performance period) to which that Bonus pertains but not later than by a designated date that is at least six (6) months prior to the end of that Plan Year (or any longer performance period in effect for that Bonus).

(B) An Eligible Employee who is first selected for participation in the Plan after the start of a Plan Year and who has not otherwise been eligible for participation in any other non-qualified elective account balance plan subject to Code Section 409A and maintained by one or more Affiliated Companies must file his or her initial Deferral Election no later than thirty (30) days after the date he or she is so selected. Such Deferral Election shall only be effective as follows:

6.2 Deferral Elections for Eligible Directors.

(a) Each Eligible Director shall have the right to file a Deferral Election with respect to the Annual Retainer to be earned by such Participant for service as an Eligible Director for the twelve (12)-month period beginning on the first day of July each Plan Year and ending on the last day of June in the succeeding Plan Year (the “Fee Period”). Each Deferral Election must be made by a written or electronic notice filed with the Administrator or its designee in which the Participant shall indicate the percentage of the Annual Retainer for the Fee Period to be deferred in accordance with the percentage limitations set forth in Section 6.5. The notice must be filed on or before the expiration date of the enrollment period designated by the Administrator for the Fee Period for which the Deferral Election is to be effective, but in no event later shall the Administrator allow any Deferral Election to be filed later than the last day of the calendar year immediately preceding the Plan Year in which the Fee Period subject to that election will begin. Notwithstanding the foregoing, the Deferral Election filed prior to the start of the 2008 Plan Year shall cover only the six (6)-month period beginning July 1, 2008 and ending December 31, 2008.

(b) An individual who first becomes an Eligible Director after the start of a Plan Year and who has not otherwise been eligible for participation in any other non-qualified elective account balance plan subject to Code Section 409A and maintained by one or more Affiliated Companies must file his or her initial Deferral Election no later than thirty (30) days after the date he or she is appointed or elected as an Eligible Director. Such Deferral Election shall only be effective with respect to the portion of the Annual Retainer attributable to Eligible Director service for the period commencing with the first day of the first calendar month following the filing of such Deferral Election and ending on the last day of the Fee Period to which that Annual Retainer pertains.

6.3 Subsequent Elections. After an initial Deferral Election is made, a new Deferral Election must be made prior to each subsequent Plan Year in order for a Participant to continue participation in the Plan for that Plan Year. Each such subsequent Deferral Election shall be effective on the first day of the Plan Year following the Plan Year in which the election is made.

6.4 Additional Provisions. The Deferral Election for an upcoming Plan Year shall become irrevocable upon the expiration date of the enrollment period designated for that Plan Year, but in no event later than the last day of the immediately preceding Plan Year (or the last date on which the Deferral Election for the Plan Year may be filed under Section 6.1 or 6.2 by a newly-eligible Participant), and no subsequent changes may be made to that Deferral Election once it becomes irrevocable. The Account maintained on behalf of each Participant will be credited with the corresponding amount of Compensation deferred by that Participant, as and when that Compensation would have otherwise become payable in the absence of his or her Deferral Election. Under no circumstances may a Deferral Election be made retroactively.

9

6.5 Deferral Percentages.

(a) The minimum deferral per Plan Year will be determined by the Administrator.

6.7 Phantom Share Program for Directors. Eligible Directors may, as part of their Deferral Election, elect to have the Annual Retainer subject to that election deferred in the form of fully vested Phantom Shares issued under the Gilead Sciences, Inc. 2004 Equity Incentive Plan. In the event of such election, the conversion of the deferred Annual Retainer (or the deferred portion thereof) into such Phantom Shares shall be effected on the first day of the Fee Period to which the deferred Annual Retainer relates. At the time of distribution, the Phantom Shares shall be converted into actual shares of Gilead Sciences, Inc. common stock or the cash value equivalent thereof, as determined by the administrator of the Gilead Sciences, Inc. 2004 Equity Incentive Plan.

6.8 Distribution Election. The initial Deferral Election made by a Participant under this Section 6 must include an election as to the time and form of payment of all Compensation deferred by that Participant under the Plan, including the Compensation deferred pursuant to that initial election and all Compensation deferred pursuant to one or more subsequent Deferral Elections.

Effective as of January 1, 2008, a Participant may make an Extended Deferral Election by submitting a completed and executed election form approved by the Administrator for such purpose; provided, however, that such Extended Deferral Election must be made at least twelve (12) months prior to the date the Participant’s Account is otherwise scheduled to become payable pursuant to the applicable provisions of Section 6 and the foregoing provisions of this Section 9, and such Extended Deferral Election shall in no event become effective or otherwise have any force or applicability until the expiration of the twelve (12)-month period measured from the date such election is filed with the Administrator. Accordingly, the Extended Deferral Election shall become null and void if the pre-existing specified commencement date or event for the distribution of the Participant’s Account occurs within that twelve (12)-month period. The Extended Deferral Election must specify a commencement date in a Plan Year that is at least five (5) Plan Years later than the Plan Year in which the distribution of the Participant’s Account would have otherwise been made or commenced in the absence of the Extended Deferral Election. As part of the Extended Deferral Election, the Participant may also elect a different method of distribution, provided the selected method complies with one of the methods of distribution permissible for that Account in accordance with the provisions of the Plan. Once the Extended Deferral Election becomes effective in accordance with the foregoing provisions of this Section 9.2, such election shall remain in effect, whether or not the Participant continues in Employee status; provided, however, that in the event of the Participant’s death, the provisions of Section 10.1 shall apply. A Participant may make only one Extended Deferral Election pursuant to this Section 9.2.

9.3 Default Distribution Election. If the Participant does not elect the method of distribution, the method of distribution will be a lump sum cash payment. Subject to Section 9.4 below, if the Participant does not elect the timing of the distribution, the Participant’s Account balance will be distributed upon his or her Separation from Service.

9.4 Delayed Distribution to Specified Employees. Notwithstanding any other provision of this Section 9, a distribution made to a Participant who is a Specified Employee at the time of his or her Separation from Service will be delayed for a minimum period of six months if the Participant’s distribution is triggered by such Separation from Service. Any payment that otherwise would have been made pursuant to this Section 9 during such period will be made in one lump sum payment not later than the last day of the eight month following the

13

month in which the Participant’s Separation from Service occurs. The determination of which Participants are Key Employees will be made by the Administrator in accordance with Section 4.1(a)(21) of the Plan and Sections 416(i) and 409A of the Code and the Treasury Regulations thereunder.

9.5 Unforeseeable Emergency. Upon application by a Participant in the event of an Unforeseeable Emergency, the Administrator may its sole discretion authorize payment of all or part of the Participant’s Account in one lump sum payment no later than the last day of the second month following the month in which the distribution is approved by the Administrator. The Administrator shall have complete discretion to accept or reject the request and shall in no event authorize a distribution from the Participant’s Account in an amount in excess of that reasonably required to meet such financial hardship and the tax liability attributable to that distribution. The minimum amount of a distribution due to a Participant’s Unforeseeable Emergency will be $1,000.00.

9.6 Prohibition on Acceleration. Notwithstanding any other provision of the Plan to the contrary, no distribution will be made from the Plan that would constitute an impermissible acceleration of payment as defined in Section 409A(a)(3) of the Code and the Treasury Regulations thereunder. However, the following mandatory distributions shall be made under the Plan:

(a) If the aggregate balance of the Participant’s Account is not greater than the applicable dollar amount in effect under Code Section 401(g)(1)(B) at the time of the Participant’s Separation from Service and the Participant is not otherwise at that time participating in any other non-qualified elective account balance plan subject to Code Section 409A and maintained by one or more Affiliated Companies, then that balance shall be distributed to the Participant in a lump sum distribution as soon as administratively practical following such Separation from Service, whether or not the Participant elected that form of distribution or distribution event, but in no event later than the later of (i) the end of the calendar year in which such Separation from Service occurs or (ii) the fifteenth (15th) day of the third (3rd) calendar month following the date of such Separation from Service, except to the extent a further deferral is required to comply with the delayed distribution requirements set forth in Section 9.4.

(b) Should the aggregate present value of all of the remaining unpaid installments due to a Participant who is receiving an installment distribution of his or her Account under the Plan fall below Twenty Thousand Dollars ($20,000), then those unpaid installments shall be paid to the Participant in a single lump sum within thirty (30) days thereafter.

9.7 Adjustment for Investment Experience. If any distribution under this Section 9 is not made in a single lump sum payment, the amount remaining in the Account after the first installment payment will be subject to adjustment (until distributed) to reflect the income and gain or loss on the investments in which such Account is deemed invested pursuant to Section 8 and any expenses properly charged under the Plan and Trust to such Account.

14

9.8 Notice to Trustee. The Administrator will notify the Trustee in writing whenever any Participant or Beneficiary is entitled to receive benefits under the Plan. The Administrator’s notice will indicate the form, amount and frequency of benefits that such Participant or Beneficiary will receive.

9.9 Time of Distribution. Except as provided in Section 9.4, in no event shall a distribution to a Participant be made or commence later than:

10.1 Distributions. In the event of a Participant’s death, the Participant’s Account shall be distributed to the Participant’s Beneficiary in a single lump sum cash payment. Such distribution shall be made as soon as administratively practicable after the date of the Participant’s death, but in no event later than the later of (i) the close of the calendar year in which the Participant’s death occurs or (ii) the fifteenth (15th) day of the third (3rd) calendar month following the date of the Participant’s death.

10.2 Beneficiary Designation.

(a) Upon enrollment in the Plan, each Participant shall file a prescribed form with the Administrator or its designate naming a person or persons as the Beneficiary who will receive distributions payable under the Plan in the event of the Participant’s death. If the Participant does not name a Beneficiary, or if none of the named Beneficiaries is living at the time payment is due, then the Beneficiary shall be the Participant’s spouse, or if none, the Participant’s children in equal shares, or if none, the Participant’s estate.

(b) The Participant may change the designation of a Beneficiary at any time in accordance with procedures established by the Administrator. Designation of a Beneficiary, or an amendment or revocation thereof, shall be effective only if made in the prescribed manner and received by the Administrator prior to the Participant’s death.

11.1 Trust. The Participating Employers shall be responsible for the payment of benefits under the Plan attributable to their respective Eligible Employees and Eligible Directors. At their discretion, the Participating Employers may establish one or more grantor trusts for the

15

purpose of providing for the payment of benefits under the Plan; provided, however, that the establishment of such a trust shall not affect the status of the Plan as an unfunded plan. Such trust or trusts may be irrevocable, but the assets thereof shall be subject to the claims of the Participating Employer’s creditors in the event of its bankruptcy or insolvency. Benefits paid the Participants from any such trust shall be considered paid by the Participating Employer for purposes of meeting that Participating Employer’s obligations under the Plan. Notwithstanding the establishment of a trust, each Participating Employer reserves the right at any time and from time to time to pay Plan benefits to Participants or their Beneficiaries in whole or in part from sources other than the Trust, in which case upon the Participating Employer’s request, that Participating Employer shall receive a distribution from the Trust in an amount equal to the amount paid by that Participating Employer from sources other than the Trust to the Participant or Beneficiary in satisfaction of its obligations under the Plan, provided that such distribution shall not exceed the amount of Trust assets previously allocated to such Participant or Beneficiary.

11.2 General Duties of Trustee. The Trustee shall manage, invest and reinvest the Trust Fund as provided in the Trust Agreement. The Trustee shall collect the income on the Trust Fund and make distributions therefrom, all as provided in the Plan and in the Trust Agreement.

12.1 Amendment by Employer. The Employer reserves the authority to amend the Plan in its sole discretion. Each such amendment will become effective on the designated effective date of that amendment. Any such amendment notwithstanding, no Participant’s Account will be reduced by such amendment below the amount to which the Participant would have been entitled had his or her Separation from Service occurred immediately prior to the date of the amendment. The Employer may from time to time make any amendment to the Plan that may be necessary to satisfy applicable requirements of the Code or ERISA. The Board or other individual(s) designated by the Board may act on behalf of the Employer for purposes of this Section 12.1. In no event shall any amendment to the Plan adversely affect the distribution provisions in effect for the Participant Accounts maintained under the Plan, and all amounts deferred prior to the date of any such Plan amendment shall continue to become due and payable in accordance with the distribution provisions of Sections 6, 9 and 10 as in effect immediately prior to such amendment. Notwithstanding the foregoing, the Senior Vice President, Human Resources (or his or her authorized delegate) shall have the authority to adopt amendments to the Plan that are required by law or provide administrative practices or clarity (specifically amendments not materially affecting either the financial obligation of the Company or the level of benefits provided to a Participant or a Beneficiary) through the Plan. Any such amendments made by the Senior Vice President, Human Resources or his or her authorized delegate) shall be subject to the limitations set forth above.

12.2 Retroactive Amendments. An amendment made by the Employer in accordance with Section 12.1 may be made effective on a date prior to the first day of the Plan Year in which adopted, if such amendment is necessary or appropriate to enable the Plan and Trust to satisfy the applicable requirements of the Code or ERISA or to conform the Plan to any change in federal law or to any regulations or ruling thereunder. Any retroactive amendment by the

16

Employer will be subject to the provisions of Section 12.1. The Board or any officer of the Company designated by the Board, including the Senior Vice President, Human Resources, shall have the authority to act on behalf of the Employer for purposes of this Section 12.2.

12.3 Termination. The Employer has adopted the Plan with the intention and expectation that contributions will be continued indefinitely. However, the Employer has no obligation or liability whatsoever to maintain the Plan for any length of time and may suspend the Plan by discontinuing contributions under the Plan or terminate the Plan at any time in its discretion without any liability hereunder for any such suspension or termination. Except as otherwise provided in Sections 12.3(a), (b) or (c) below, the termination of the Plan shall not affect the distribution provisions in effect for the Participant Accounts maintained hereunder, and all amounts deferred prior to the date of any such Plan termination shall continue to become due and payable in accordance with the distribution provisions of Sections 6, 9 and 10 as in effect immediately prior to such plan termination.

(a) Except as provided in Sections 12.3(b) and (c) below, in the event of a termination of the Plan during a period in which the Employer has not experienced a financial downturn, the Participant Accounts maintained under the Plan may, in the Employer’s discretion, be distributed within the period beginning twelve (12) months after the date the Plan is terminated and ending twenty-four (24) months after the date of such plan termination, or pursuant to Section 6, 9 or 10 of the Plan, if earlier. If the Plan is terminated and Accounts are distributed, the Employer and the other Participating Employers shall also terminate and liquidate all other non-qualified elective account balance deferred compensation plans maintained by them and shall not adopt a new non-qualified elective account balance deferred compensation plan for at least three (3) years after the date the Plan is terminated.

(b) The Employer and the other Participating Employers may terminate the Plan thirty (30) days prior to or within twelve (12) months following a Change of Control and distribute, within the twelve (12)-month period following the termination of the Plan, the Accounts of the Participants affected by such Change in Control If the Plan is terminated and Accounts are distributed, the Employer and the other Participating Employers shall also terminate all other non-qualified elective account balance deferred compensation plans sponsored by them in which such Participants participate, and all of the benefits accrued under those terminated plans by such Participants shall be distributed to them within twelve (12) months following the termination of such plans.

(c) The Employer may terminate the Plan upon a corporate dissolution of the Employer that is taxed under Section 331 of the Code or with the approval of a bankruptcy court pursuant to 11 U.S.C. Section 503(b)(1)(A), provided that the Participant Accounts are distributed and included in the gross income of the Participants by the later of (i) the Plan Year in which the Plan terminates or (ii) the first Plan Year in which payment of the Accounts is administratively practicable.

13.1 Withholding Taxes. All distributions under the Plan shall be subject to reduction in order to reflect tax withholding obligations imposed by law.

17

13.2 Participant’s Unsecured Rights. The Account of any Participant, and such Participant’s right to receive distributions from his or her Account, shall be considered an unsecured claim against the general assets of the Employer; such Accounts are unfunded bookkeeping entries. The Employer considers the Plan to be unfunded for tax purposes and for purposes of Title I of ERISA. No Participant shall have an interest in, or make claim against, any specific asset of the Employer (or any other Participating Employer) pursuant to the Plan.

13.3 Limitation of Rights. Neither the establishment of the Plan and the Trust, nor any amendment thereof, nor the creation of any fund or account, nor the payment of any benefits, will be construed as giving to any Participant or other person any legal or equitable right against any Participating Employer, the Administrator or the Trustee, except as provided herein. In no event shall the terms of employment or service of any Participant be modified or in any way affected hereby.

13.4 Nonalienability of Benefits. Except as provided in Sections 13.4(a) and (b) with respect to domestic relations orders, the benefits provided hereunder will not be subject to alienation, assignment, garnishment, attachment, execution or levy of any kind, either voluntarily or involuntarily, and any attempt to cause such benefits to be so subjected will not be recognized, except to such extent as may be required by law.

(a) The procedures established by the Administrator for the determination of the qualified status of domestic relations orders and for making distributions under qualified domestic relations orders, as provided in Section 206(d) of ERISA, shall apply to the Plan, to the extent applicable.

(b) To the extent required to comply with a qualified domestic relations order, amounts awarded to an alternate payee under a qualified domestic relations order shall be distributed in the form of a lump sum distribution as soon as administratively feasible following the determination of the qualified status of the domestic relations order. To the extent that the qualified domestic relations order does not require an immediate lump sum distribution, the alternate payee shall have all rights regarding investment elections and distribution elections and withdrawal rights as if such alternate payee were a Participant. For purposes of determining distributions to an alternate payee, “Separation from Service” shall be the Separation from Service of the Participant whose Account is the subject of the qualified domestic relations order.

13.5 Facility of Payment. In the event the Administrator determines, on the basis of medical reports or other evidence satisfactory to the Administrator, that the recipient of any benefit payments under the Plan is incapable of handling his or her affairs by reason of minority, illness, infirmity or other incapacity, the Administrator may direct the Trustee to disburse such payments to a person or institution designated by a court which has jurisdiction over such recipient or a person or institution otherwise having the legal authority under state law for the care and control of such recipient. The receipt by such person or institution of any such payments will be complete acquittance therefore, and any such payment to the extent thereof, will discharge the liability of the Participating Employer and the Trust for the payment of benefits hereunder to such recipient.

18

13.6 Governing Law. The validity, interpretation, construction and performance of the Plan shall be governed by ERISA, and, to the extent that they are not preempted, by the laws of the State of California, excluding California’s choice-of-law provisions.
