VALERO GP, LLC

SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN

The Valero GP, LLC Supplemental Executive Retirement Plan (hereinafter referred to as the “SERP” or the “Plan”) is hereby established effective July 1, 2006 for the purpose of providing certain highly compensated, management personnel of Valero GP, LLC and its subsidiaries (hereinafter collectively referred to as the “Company”) a supplement to the retirement benefit they may otherwise receive under the Valero GP, LLC Pension Plan (the “Pension Plan”) and the Valero Energy Corporation Pension Plan (“Prior Pension Plan”).

Benefits under the Plan are limited to a select group of management or other highly compensated employees. The Plan is not intended to constitute either a qualified plan under the provisions of Section 401 of the Code or a funded plan subject to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).

The Plan is established in connection with a spin-off from the Valero Energy Corporation Supplemental Executive Retirement Plan (“Predecessor SERP”) of the benefits accrued under such Predecessor SERP with respect to eligible Employees of the Company. In this connection, it is the intent of the Company that this Plan not constitute a new nonqualified deferred compensation plan, but rather merely an assumption and continuation of the Predecessor SERP, effective as of July 1, 2006, with respect to eligible Employees of the Company who have accrued a benefit under the Predecessor SERP. The original effective date of the Predecessor SERP was January 1, 1983.

The Company has established the Pension Plan effective as of July 1, 2006, to provide defined benefit pension benefits to eligible Employees of the Company, with respect to future service. Effective as of July 1, 2006, eligible Employees of the Company will cease accruing additional benefits under the Prior Pension Plan and the Prior SERP. It is the intent of the

Company that this Plan shall assume the liabilities of the Prior SERP as of July 1, 2006, with respect to eligible Employees of the Company, and shall provide a single, nonqualified defined benefit to eligible Employees for their pre-July 1, 2006 benefit accruals under the Predecessor SERP and their post-July 1, 2006 benefit accruals under this Plan.

It is the intent of the Company and Valero Energy Corporation (“VEC”) that this Plan be maintained by the Company for the benefit of eligible Employees of the Company and that, from and after the effective date hereof, this spin-off plan and the Company shall be solely liable for all benefits due such eligible Employees under this Plan and the Predecessor SERP.

ELIGIBILITY

2.1 Eligibility. An Employee shall become a Participant in the Plan as of the date he is selected by the Committee for inclusion as a Participant in the Plan. Ongoing eligibility and participation of Participants shall be determined by the Committee in its sole discretion, and no employee shall have a right to initial or ongoing participation in this Plan. As of the Effective Date, any Employee who was a participant in the Prior SERP shall automatically become a Participant in this Plan.

2.2 Frozen Participation. If an Employee who is a Participant later becomes ineligible to continue to participate but still is employed by an adopting Company, his Accrued Benefit will be frozen as of the last day of the Plan Year prior to the Plan Year during which he initially became ineligible to participate. He will later be entitled to that frozen Accrued Benefit, upon his Separation from Service (if, at the time of such Separation from Service, his Accrued Benefit is vested), subject to the requirements of Articles III and IV. The frozen Accrued Benefit will be payable at the time and in the form set forth in Article IV. The Surviving Spouse of a Participant whose Accrued Benefit is frozen at the time of the Participant’s death shall not be entitled to any death benefit under this Plan. A Participant whose Accrued Benefit is frozen at the time of incurring a disability shall not accrue any further Credited Service either for accrual or vesting purposes after the disability occurs so long as the Participant’s Accrued Benefit in this Plan is frozen. If the frozen Accrued Benefit is less than the benefit which could otherwise be provided without this limitation, then the benefit will not exceed the Participant’s frozen Accrued Benefit. Additionally, if any of the events described in Article VI should occur, the Participant whose Accrued Benefit is frozen shall be subject to having his frozen Accrued Benefit either restricted in amount or forfeited in accordance with Article VI.

2.3 Renewed Eligibility. If an employee who is a Participant becomes ineligible to continue to participate but remains employed by an adopting Company and then later again becomes eligible to participate, the Participant will be given Credited Service for the intervening period, will have his Final Average Compensation computed as though the freeze had never occurred, and will be treated for all purposes as though he had not had his participation interrupted.

VESTING

Except as otherwise set forth herein, a Participant’s Accrued Benefit shall vest pursuant to the following vesting schedule:

Notwithstanding the foregoing, the portion of a Participant’s Accrued Benefit attributable to Credited Service attained on or after January 1, 1996, shall vest only upon the occurrence of the Participant’s (i) death, (ii) Disability, or (iii) Separation from Service after the participant has attained age 55 and 5 years of Credited Service. In the event of the Participant’s Separation from Service prior to attaining age 55 and 5 years of Credited Service for any reason other than death or Disability, the Participant’s Accrued Benefit hereunder shall be forfeited, and, in such case, the Participant shall be eligible for benefits under the Valero GP, LLC Excess Pension Plan if, and to the extent, the Participant satisfies the eligibility criteria for benefits under such plan.

ARTICLE IV

RETIREMENT BENEFIT

4.1 Calculation of Retirement Benefit. Subject to the following provisions of this Section 4.1, the provisions of Section 4.3 and Article III; the monthly pension payable under the Plan shall be an amount equal to the sum of (i) plus (ii) minus (iii) where (i) equals: 1.60% of the Participant’s Final Average Compensation multiplied by his number of years of Credited Service; and (ii) equals .35% multiplied by the product of his number of years of Credited Service (not to exceed 35 years) times the excess of his Final Average Compensation over the lesser of (a) 1.25 times his Monthly Covered Compensation, or (b) the Monthly FICA Amount; and (iii) equals the sum of the Participant’s Pension Plan Benefit and Prior Pension Plan Benefit. In the case of an unmarried Participant the benefit shall be based on a lifetime annuity. In the case of a married Participant the benefit shall be a fifty percent (50%) Qualified Joint and Survivor Annuity pension of Actuarially Equivalent Value to the pension otherwise payable for life hereunder. The monthly pension payable under the Plan, as determined above, shall be further reduced by the equivalent amount the Pension Plan Benefit and the Prior Pension Plan Benefit are increased as a result of increases in the amount of maximum benefits payable from qualified plans in accordance with Code Section 415 or other applicable law. If a Participant’s benefits commence prior to his Normal Retirement Date, the monthly pension payable to such Participant shall be determined by multiplying the monthly pension otherwise payable to him by the applicable early retirement reduction factor contained in the Pension Plan.

4.2 Form and Time of Payment. Benefits under the Plan shall commence upon the Participant’s Separation from Service. In the event that the present lump-sum Actuarial Value of a Participant’s benefit at Separation from Service is $50,000 or less, such benefit shall be paid in a single lump sum cash payment. In the event that the present lump-sum Actuarial Value of a

Participant’s benefit at Separation from Service is greater than $50,000, such benefits shall be made available to the Participant only in the form of the monthly annuity payment forms available to the Participant under the Pension Plan which are Actuarial Equivalent lifetime annuities. Any optional annuity form normally available under the Pension Plan that is coordinated with such Participant’s Social Security benefit, or is not an Actuarial Equivalent lifetime annuity, shall not be an available optional payment form under this Plan. In that regard, the Company shall furnish each Participant, on or about 180 days prior to the date on which he will have both attained age 55 and completed five years of Credited Service, or, if earlier, the date he will have attained age 65, a written explanation of (a) the terms and conditions of payment provided under the form of payments as described in the Pension Plan and the optional forms of payment which may be elected in lieu thereof; (b) the terms and conditions of payment provided under the automatic pension as described in the Pension Plan; and (c) the relative financial effect on a Participant’s total pension of an election not to take the standard and automatic pension. In addition, the Company shall also furnish each married Participant at least 120 days prior to the date his benefit is scheduled to commence under the Plan, a written statement of the amount of pension which would be payable on his behalf under the standard and automatic Qualified Joint and Survivor Annuity pension as is described in the Pension Plan; and the amount of pension otherwise payable under the available optional forms of benefit.

4.3 Modification of Pension. The Committee shall have the right to modify the calculation of the benefit payable as to any Participant as it may desire from time to time; provided, however, that any such modification shall not result in a reduction of the benefit payable below the amount set forth above in Section 4.1. In addition, except as expressly provided for herein, benefits payable under this Plan to any Participant shall not affect any other right or entitlement a Participant may have by contract or otherwise. In addition, the benefits payable to a Participant under this Plan may be modified by written agreement entered into between the Participant and a Company and approved pursuant to Section 7.7. If so modified, the provisions of such written agreement shall prevail in determining such Participant’s rights and benefits under this Plan.

4.4 Delay of Certain Payments. With respect to any Participant who is a “Specified Employee,” as defined in Code Section 409A and the regulations and rulings issued thereunder, any benefit that becomes payable by reason of such Participant’s Separation from Service shall not commence prior to the date that is six (6) months following such Participant’s Separation from Service. Upon commencement of any benefit delayed by application of this Section 4.4, the monthly benefit payable to the Participant shall be determined as of the Participant’s Separation from Service, and the first payment shall include all payments that would have otherwise becomes payable during the period of such delay. The provisions of this Section 4.4 shall not apply (a) with respect to any benefit that becomes payable due to the death of the Participant, or (b) if, at the time of such Participant’s Separation from Service, no stock of the Company is publicly traded on an established securities market or otherwise.

ARTICLE V

PRERETIREMENT SPOUSAL DEATH BENEFIT

5.1 Death Prior to Commencement of Benefits. In the event that a Participant dies prior to commencing payment of his benefit hereunder, the Participant’s Surviving Spouse shall receive for life a Surviving Spouse benefit under the Plan, which shall continence on the first day of the month following the date of the Participant’s death and shall be equal to fifty percent (50%) of the amount the Participant would have received under Section 4.1 if he had experienced a Separation from Service on his date of death and elected immediate commencement of his pension on his Separation from Service.

5.2 Death After Commencement of Benefits. Upon the death of a Participant at or after the date that the Participant has commenced payment of his benefit hereunder, there is no separate death benefit and the Surviving Spouse shall be entitled to receive only the survivor portion of any benefit otherwise payable, based upon the form of annuity elected by the Participant under Section 4.1.

5.3 Beneficiary Designation Prohibited. Since the only death benefit payable under the Plan is to a Surviving Spouse, and no Participant shall have the right to designate a beneficiary to receive death benefits hereunder.

PROVISIONS RELATING TO ALL BENEFITS

6.1 Effect of This Article. The provisions of this Article will control over all other provisions of this Plan.

6.2 Termination of Employment. Termination of employment for any reason prior to the participant’s vesting under Article III or Article V, if applicable, will cause the Participant and any Surviving Spouse to forfeit all interest in and under this Plan.

6.3 No Duplication of Benefits. It is not intended that there be any duplication of benefits. Therefore, in no event will a Participant and/or such Participant’s Surviving Spouse qualify for a benefit under both Articles IV and V.

If the Committee finds, after full consideration of the facts presented on behalf of both the Company and a Participant, that the Participant was discharged by a Company for fraud, embezzlement, theft, commission of a felony, proven dishonesty in the course of his employment by a Company which damaged the Company, or for disclosing trade secrets of a Company, the entire benefit accrued for the benefit of the Participant and/or his Surviving Spouse will be forfeited even though it may have been previously vested under Article III or V. The decision of the Committee as to the cause of a former Participant’s discharge and the damage done to the Company will be final. No decision of the Committee will affect the finality of the discharge of the Participant by the Company in any manner. Notwithstanding the foregoing, no forfeiture should be permitted pursuant to this Section following Plan termination or a Change in Control unless pursuant to arbitration consistent with the provisions of Section 11.3.

6.5 Forfeiture for Competition. If at the time a distribution is being made or is to be made to a Participant, the Committee finds after full consideration of the facts presented on behalf of the Company and the Participant, that the Participant at any time within two years following his termination of employment from all Companies and without written consent of a Company, directly or indirectly owns, operates, manages, controls or participates in the ownership (other than through ownership of less than 5% of the common stock of a publicly traded entity), management, operation or control of or is employed by, or is paid as a consultant or other independent contractor by a business which competes with the Company by which he was formerly employed in a trade area served by the Company at the time distributions are being made or to be made and in which the Participant had represented the Company while employed by it; and if the Participant continues to be so engaged 60 days after written notice has been given to him, the Committee may forfeit all benefits otherwise due the Participant even though such benefit may have been previously vested under Article III or V. Notwithstanding the foregoing, no forfeiture shall be permitted pursuant to this Section following Plan termination or a Change in Control unless pursuant to arbitration consistent with the provisions of Section 11.3.

6.6 Expenses Incurred in Enforcing the Plan. The Company will pay a Participant for all reasonable legal fees and expenses incurred by him in successfully contesting or disputing his termination of employment by a Company or in successfully seeking to obtain or enforce any benefit provided by this Plan if such termination occurs or a benefit is payable following a Change in Control.

6.7 No Restrictions on any Portion of Total Payments Determined to be Excess Parachute Payments. Notwithstanding that any payment or benefit received or to be received by a Participant in connection with a Change in Control, or the termination of his employment by a Company, would not be deductible, whether in whole or in part, by a Company or any affiliated company, as a result of Section 280G of the Code, the benefits payable under this Plan shall nevertheless not be reduced.

6.8 Benefits Upon Re-employment. If a former employee who is receiving benefit payments under this Plan is re-employed by the Company, the payment of the benefit will continue during his period of re-employment. The re-employed former employee’s benefit will not be changed as a result of his re-employment.

10.1 Payments from Trust. As set forth in Section 8.1, the Companies are jointly and severally liable to pay the benefits due under this Plan. The Companies may establish, but shall not be required to establish a Trust to provide for the funding of benefits hereunder.

10.2 Plan May Be Funded Through Life Insurance. It is specifically recognized that the Company may, but is not required to, purchase life insurance so as to accumulate assets sufficient to fund obligations under this Plan and that the Company may, but is not required to contribute any policy or policies it may purchase and any amount it finds desirable to the Trust or any other trust established to accumulate assets to fund obligations under this Plan. However, under all circumstances, the Participants will have no rights in or to any such policies.

10.3 Funding of Rabbi Trust. To the extent the Company establishes a Trust hereunder, the Company may make contributions of cash or other assets to the Trust, but shall not be required to make contributions thereto in any amount. Notwithstanding the foregoing, the Company may require that a Subsidiary adopting the Plan make contributions to the Trust in an amount sufficient to satisfy the liability accrued under the Plan to Participants while employed by such Subsidiary.

10.4 Ownership of Assets; Release. All policies of insurance or other assets contributed to the Trust (or to any other trust established for the purpose of funding benefits hereunder) pursuant to Sections 10.2, 10.3 or otherwise shall be contributed by the Company, and all such policies or other assets shall be owned solely by the Company immediately prior to such contribution. No Participant shall contribute policies or assets to the Trust. As an internal accounting matter, the Company may allocate liabilities under the Plan to the various Subsidiaries adopting the Plan. The Company may charge or allocate all or any part of such contributions to Subsidiaries adopting the Plan in any reasonable manner determined by the Company in accordance with generally accepted accounting principles, and may record the amounts so allocated as obligations owing among the Company and such Subsidiaries. The Company may also allocate or distribute assets received by it from the Trust pursuant to Section 10.5 hereof to such Subsidiaries in any reasonable manner determined by the Company in accordance with generally accepted accounting principles. However, notwithstanding the fact that a Subsidiary may be deemed to have a claim against the Company with respect to such contributions or distributions, no Subsidiary shall at any time own or be deemed to own or have any contingent, reversionary or other beneficial interest in any portion of the policies and other assets held in the Trust or any claim, against the Trustee or otherwise, with respect thereto. Each Subsidiary, in consideration of the mutual covenants herein contained, for itself, its successors, assigns, representatives, administrators, trustees and other persons claiming by, through or under such Subsidiary, hereby irrevocably and forever releases and relinquishes (i) any and all rights, claims and interests (beneficial, reversionary, actual, contingent or otherwise), known or unknown, asserted or unasserted, which it has or may have, or may hereafter have, in or with

respect to the Trust, the Trust Fund (as such term is defined in the Trust Agreement) and the policies and assets now or hereafter from time to time contributed or contributable thereto, held therein or thereby, or distributable therefrom or thereby, and (ii) any claim, demand, action or cause of action whatsoever which it has or may have, or may hereafter have, against the Trustee, its successors or assigns, with respect thereto.

10.5 Reversion of Excess Assets. Assets held pursuant to the Trust shall not be loaned to any Company. However, the Company may, at any time, request the actuary who last performed the annual actuarial valuation of the Pension Plan to determine the Actuarial Equivalent of the Accrued Benefits, assuming the Accrued Benefits to be fully vested (whether they are or not), as of the end of the Plan Year coincident with or last preceding the request, of all Participants and Surviving Spouses of deceased Participants for which the Company is or will be obligated to make payments under this Plan. If the fair market value of the assets held in the Trust, as determined by the Trustee as of that same date, exceeds the Actuarial Equivalent of the Accrued Benefits of all such Participants and Surviving Spouses by not less than 25%, then the Company may direct the Trustee to return to the Company that part of the assets which is in excess of 125% of the Actuarial Equivalent of the Accrued Benefits. If the Plan has terminated, all assets held in the Trust following the distribution of all Accrued Benefits under the Plan shall revert to the Company.

10.6 Participants Must Rely Only on General Credit of the Companies. The provisions of Sections 10.2 and 10.3 notwithstanding, it is specifically recognized by the Company and the Participants that this Plan is an unsecured corporate commitment and that each Participant (and any Surviving Spouse or other person claiming through a Participant) must rely upon the general credit of the Company for the fulfillment of its obligations under this Plan. Nothing contained in this Plan or in the Trust Agreement will constitute a representation, covenant or guarantee by the Company that the policies and assets transferred to the Trust (or any other trust established for the purpose of funding benefits hereunder) or the general assets of the Company will be sufficient to pay any or all benefits under this Plan Neither this Plan nor the Trust creates any secured or priority position, preferential right, lien, claim, encumbrance, right, title or other interest of any kind in any Participant in any policy or other asset held by the Company, contributed to the Trust (or any other trust established for the purpose of funding benefits hereunder) or otherwise designated to be used for payment of any obligations created in this Plan. No policy or other specific asset of the Company has otherwise been or will be set aside, or has been or will be pledged in any way for the performance of obligations under this Plan, which would remove the policy or asset from being subject to the claims of the general creditors of the respective Company. The Trust Agreement (and any other agreement entered into to fund obligations under this Plan) shall specify that, with respect to their benefits under this Plan, the Participants (and any Surviving Spouse or other person claiming through a Participant) are only unsecured general creditors.

ARTICLE XI

MISCELLANEOUS

11.1 Responsibility for Distributions and Withholding of Taxes. The Company shall calculate the amount of any distribution payable to a Participant hereunder, and the

amounts of any deductions required with respect to federal, state or local tax withholding, and shall withhold or cause the same to be withheld. However, any and all taxes payable with respect to any distribution or benefit hereunder shall be the sole responsibility of the Participant, not of the Company or any Company, whether or not the Company or any Company shall have withheld or collected from the Participant any sums required to be so withheld or collected in respect thereof and whether or not any sums so withheld or collected shall be sufficient to provide for any such taxes. Without limitation of the foregoing, and except as may otherwise be provided in any separate employment, severance or other agreement between the Participant and any Company, the individual Participant or Surviving Spouse, as the case may be, shall be solely responsible for payment of any excise, income or other tax imposed (i) upon any payment hereunder which may be deemed to constitute an “excess parachute payment” pursuant to Section 4999 of the Code, or (ii) based upon any theory of “constructive receipt” of any lump-sum or other amount hereunder.

11.2 Limitation of Rights. Nothing in this Plan will be construed:

(a) to give a Participant or other person claiming through him any right with respect to any benefit except in accordance with the terms of this Plan or an agreement modifying rights under this Plan;

(b) to limit in any way the right of the Company to terminate a Participant’s employment with the Company at any time;

(c) to evidence any agreement or understanding, expressed or implied, that the Company will employ a Participant in any particular position or for any particular remuneration; or

(d) to give a Participant or any other person claiming through him any interest or right under this Plan other than that of any unsecured general creditor.

11.3 Resolution of Disputes. It is agreed that any and all disputes, claims, (whether tort, contract, statutory or otherwise) and/or controversies which relate in any manner to the Plan shall, subject to the provisions of Article VII, be submitted to the Company’s established dispute resolution program applicable to employees generally.

11.4 Distributions to Incompetents. Should a Participant or a Surviving Spouse be incompetent at the time any payment is due hereunder, as determined by the Committee in its sole discretion, the Company is authorized to make such payment to the guardian or conservator of the incompetent Participant or Surviving Spouse or directly to the Participant or Surviving Spouse or to apply those funds for the benefit of the incompetent Participant or Surviving Spouse in any manner the Committee determines in its sole discretion.

11.5 Nonalienation of Benefits. No right or benefit provided in this Plan will be transferable by the Participant, except upon his death to a Surviving Spouse as provided in this Plan. No right or benefit under this Plan will be subject to anticipation, alienation, sale, assignment, pledge, encumbrance or charge, and any attempt to anticipate, alienate, sell, assign, pledge, encumber, or charge the same will be void. No right or benefit under this Plan will in any manner be liable for or subject to any debts, contracts, liabilities or torts of the person entitled to

such benefits. If any Participant or any Surviving Spouse becomes bankrupt or attempts to anticipate, alienate, sell, assign, pledge, encumber or charge any right or benefit under this Plan, that right or benefit will, in the discretion of the Committee, cease. In that event, the Committee may have the Company hold or apply the right or benefit or any part of it to the benefit of the Participant or Surviving Spouse, his or her spouse, children or other dependents or any of them in any manner and in any proportion the Committee believes to be proper in its sole and absolute discretion, but is not required to do so.

11.6 Severability. If any term, provision, covenant or condition of this Plan is held to be invalid, void or otherwise unenforceable, the rest of this Plan will remain in full force and effect and will in no way be affected, impaired or invalidated.

11.7 Notice. Any notice or filing required or permitted to be given to a Company, the Committee or a Participant will be sufficient if in writing and hand delivered or sent by U.S. mail to the principal office of the Company, acting on behalf of the Company or Committee, or to the residential mailing address of the Participant. Notice will be deemed to be given as of the date of hand delivery or if delivery is by mail, as of the date shown on the postmark.

11.8 Gender and Number. If the context requires it, words of one gender when used in this Plan will include the other gender, and words used in the singular or plural will include the other.

11.9 Governing Law. The Plan will be construed, administered and governed in all respects by the laws of the State of Texas.
