The following provisions address the potential transition of additional employees from VEC to GP and also specifically apply for purposes of determining Post- Second Tranche Eligible GP Employees who are eligible to benefit from the agreements entered into herein with respect to the transition of employee benefit plans:

(a) Extension to and Acceptance of Offers by Indirect and No Service Employees. Any VEC Employee, including those that presently provide services indirectly to Xxxxxx X.X. and/or its affiliates (referred to herein as “Indirect Employees”) and those that presently provide no services to Xxxxxx X.X. and/or its affiliates (referred to herein as “No Service Employees”) may become employees of GP and be considered Post-Second Tranche Eligible GP Employees in accordance with the following provisions:

(i) By Xxxxx 0, 0000, XX must provide VEC with a list of Indirect Employees and No Service Employees to whom it is considering making an offer of employment.

(ii) By April 1, 2007, GP must provide VEC with a list of all Indirect Employees and No Service Employees to whom it has made offers of employment (the “GP Offer List”). The offers are subject to the following restrictions:

1. Offers for No Service Employees must provide that employment starts with GP no later than the Last Move Date (as defined in the Services Agreement) or May 15, 2007, whichever is later.

2. Offers for Indirect Employees must provide that employment starts with GP no later than the relevant Optional Termination Date (as defined in the Services Agreement) or May 15, 2007, whichever is later.

(iii) VEC may elect to make offers to any of the VEC Employees listed on the GP Offer List in its sole discretion. By April 15, 2007, VEC must provide GP with a list of all Indirect Employees and No Service Employees to whom it has made offers of employment.

(iv) GP and VEC may only make one offer to an employee, which offer cannot be subsequently modified in any material way.

(v) By May 1, 2007, GP must provide VEC with a list (the “Final GP List”) of those Indirect Employees and No Service Employees that have accepted offers of employment from GP, including the proposed start date (which may not be any later than the applicable dates identified in (ii) above).

(b) Post-Second Tranche Eligible GP Employees. Only those Indirect Employees and No Service Employees (i) listed on both the GP Offer List and the Final GP List or (ii) expressly agreed upon in a signed writing between VEC and GP no later than February 28, 2007, will be considered Eligible GP Employees for purposes of this Agreement (“Post-Second Tranche Eligible GP Employee”). No other Indirect Employees or No Service Employees hired by GP will be considered Eligible GP Employees for purposes of this Agreement.

(c) Secondment of Certain Employees. If an Indirect Employee accepts an offer from GP, VEC will “second” the Indirect Employee to GP from and after the earlier of (A) May 15, 2007 or (B) the acceptance by an Indirect Employee of an offer of employment from GP, until the earlier of (A) the starting date of employment with GP or the relevant Optional Termination Date (as defined in the Services Agreement). The cost to second these Indirect Employees for this period will be deemed to be included in the Administrative Service Fee for that particular Service (all as defined in the Services Agreement).

(d) Termination of Employment. Indirect Employees and No Service Employees that accept offers from GP, whether or not determined to be a Post-Second Tranche Eligible GP Employee, will be deemed to have voluntarily resigned from employment with VEC effective upon his or her starting date of employment with GP.

6. Pension Plan.

(a) GP Pension Plan. GP has adopted a defined benefit pension plan (“GP Pension Plan”) effective as of July 1, 2006, to cover Eligible GP Employees, as well as other individuals subsequently employed by GP and determined to be eligible under the terms of the GP Pension Plan. The GP Pension Plan provides all Eligible GP Employees with service credit for purposes of vesting and eligibility for all service credited by VEC under the Valero Energy Corporation Pension Plan (“VEC Pension Plan”) for such purposes. Additionally, Final Average Salary (as defined in the GP Pension Plan) includes eligible compensation earned by Eligible GP Employees while covered under the VEC Pension Plan, as well as eligible compensation earned with GP after July 1, 2006 or the Cut-Over Date, as applicable.

(b) VEC Pension Plan. Effective as of July 1, 2006, GP shall cease to be a participating employer under the VEC Pension Plan and all Eligible GP Employees, effective July 1, 2006 or the Cut-Over Date, as applicable, shall no longer be eligible to accrue additional credited service for purposes of accruing additional benefits under the VEC Pension Plan. VEC shall amend the VEC Pension Plan to provide that, for purposes of calculating the benefits of each Eligible GP Employee, Final Average Salary (as defined in the VEC Pension Plan) shall include all eligible compensation earned by the Eligible GP Employee while employed by GP (or an affiliate of GP provided, and for so long as, such affiliate maintains a traditional formula-based defined benefit pension plan) following July 1, 2006 or the Cut-Over Date, as applicable, and prior to the earlier of the date that the Eligible GP Employee commences his/her benefit under the VEC Pension Plan, or separates from service from GP. GP or its affiliate, as appropriate, shall provide to VEC an affidavit to be certified by an appropriate representative setting forth the amount of earned compensation and years of service with the respective entity to be used in determining Final Average Salary as contemplated in the preceding sentences. VEC shall amend the VEC Pension Plan further to provide that vesting service under the VEC Pension Plan shall include all service with GP following July 1, 2006 or the Cut-Over Date, as applicable, prior to the date that the Eligible GP Employee commences his/her benefits under the VEC Pension Plan.

7. Retiree Welfare Benefits. GP has adopted a retiree welfare benefit plan effective July 1, 2006 that will offer retiree coverage for medical, dental, prescription drug, vision and life insurance benefits for eligible retirees of GP, as determined by GP from time to time, beginning January 1, 2007. The parties agree that VEC will provide retiree welfare benefits under the VEC retiree welfare benefit plan, as it may be amended from time to time, for Eligible GP Employees who: (i) as of July 1, 2006, are at least age fifty-five (55) and have at least five (5) years of credited service recognized by VEC under the VEC Pension Plan; or (ii) on or prior to December 31, 2006, are eligible for, and elect to begin receiving, a pension benefit under the VEC Pension Plan and, coincident with such pension benefit commencement, elect to commence retiree welfare plan coverage.

8. Active Employee Welfare Benefits.

(a) Welfare Plan Transition Period. Health and welfare benefit coverage for Eligible GP Employees, as well as other individuals subsequently employed by GP and determined to be eligible under the terms of the applicable welfare plan sponsored by GP, and their eligible dependents, shall, during the period beginning July 1, 2006 and ending December 31, 2006, or such other date to which the parties may agree (“Welfare Plan Transition Period”), continue to be provided under the VEC welfare benefit plans, subject to the respective terms of such plans, as they may be amended from time to time. VEC will also be responsible for providing any required COBRA coverage for Eligible GP Employees and dependents whose COBRA qualifying event occurs during the Welfare Plan Transition Period, and for administering any QMCSOs received during the Welfare Plan Transition Period. With respect to the continuation of coverage during the Welfare Plan Transition Period for the Eligible GP Employees and their dependents, GP shall continue to be charged by VEC the percentage of payroll attributable to the overall benefit costs as determined on January 1, 2006 (such percentage being 50.6%, a portion of which relates to the provision of welfare benefits).

(b) GP Welfare Plans. As of the expiration of the Welfare Plan Transition Period, GP will have established its welfare benefit plans for Eligible GP Employees and their dependents, as well as other individuals subsequently employed by GP and determined to be eligible under the terms of the applicable welfare plan sponsored by GP, and, as of January 1, 2007 or the Cut-Over Date, as applicable, such individuals shall no longer be eligible for coverage or benefits under the VEC welfare benefit plans, except as may be required under COBRA for qualifying events that occurred during the Welfare Plan Transition Period.

(c) Special Provisions Regarding Long-Term Disability/Health and Welfare Benefits. Consistent with the foregoing provisions of this Section 8, VEC shall continue to provide long-term disability (“LTD”) pay continuance coverage to Eligible GP Employees during the Welfare Plan Transition Period under the VEC LTD plan, as it may be amended from time to time. However, GP will be obligated for the cost of LTD benefits (pay continuance and/or health and welfare benefits, as applicable) to those individuals identified on Schedule A during the Welfare Plan Transition Period and going forward shall provide such benefits under GP LTD and health and welfare plans. The transfer of liabilities relating to the individuals identified on Schedule A are more particularly described in Exhibit A. At the expiration of the Welfare Plan Transition Period, VEC shall be obligated solely with respect to the provision of LTD pay continuance benefits for any Eligible GP Employee (other than those former Kaneb employees listed on Schedule A) who is or becomes eligible to receive LTD pay continuance benefits due to a disability that occurs on or before December 31, 2006, such LTD pay continuance benefits to be payable in accordance with the terms of the applicable insurance policy sponsored by VEC. Also at the expiration of the Welfare Plan Transition Period, each entity shall be responsible for the LTD coverage and benefits that may become payable to its respective employees due to a disability that occurs on or

after January 1, 2007. The parties shall cooperate with each other and coordinate the transfer of appropriate individuals from the VEC LTD and health and welfare plans to the GP LTD and health and welfare plans consistent with the provisions of this paragraph.

(d) Section 125 Plan. During the period beginning July 1, 2006 and ending at the expiration of the Welfare Plan Transition Period, Eligible GP Employees will continue to be eligible to participate in the VEC flexible benefits plan under Code section 125, subject to its terms and conditions as they may be amended from time to time. The existing elections for Eligible GP Employees participating in the VEC flexible benefits plan during 2006 shall remain in effect throughout 2006 subject to any changes permitted under the VEC flexible benefits plan. Effective as of the expiration of the Welfare Plan Transition Period, Eligible GP Employees shall cease participation in the VEC flexible benefits plan, and GP may establish a flexible benefits plan under Code section 125 for Eligible GP Employees.

9. Thrift Plan. Effective as of July 1, 2006, GP adopted a defined contribution retirement plan (“XX Xxxxxx Plan”) for Eligible GP Employees as well as other individuals subsequently employed by GP and determined to be eligible under the terms of the XX Xxxxxx Plan. GP Employees who were participating in the Valero Energy Corporation Thrift Plan (“VEC Thrift Plan”) immediately prior to the adoption of the XX Xxxxxx Plan began participating in the XX Xxxxxx Plan effective as of July 1, 2006, at the same contribution rate as then in effect under the VEC Thrift Plan. Eligible GP Employees are deemed to have incurred a termination of employment for purposes of the VEC Thrift Plan as of the later of the effective date of the Initial Tranche or the Cut-Over Date, and all accrued benefits of Eligible GP Employees under the VEC Thrift Plan shall be deemed to be fully vested as of July 1, 2006 or the Cut-Over Date, as applicable. The XX Xxxxxx Plan shall accept direct rollovers of the account balances of Eligible GP Employees under the VEC Thrift Plan, and shall provide credit to all Eligible GP Employees for purposes of eligibility and vesting for all service credited by VEC for such purposes under the VEC Thrift Plan. The parties will cooperate with each other to establish and implement one or more special direct rollover “window” opportunities for Eligible GP Employees to roll over their account balances under the VEC Thrift Plan (including, for such special direct rollover window periods, outstanding plan loans) to the XX Xxxxxx Plan on such terms as the parties agree.

10. Equity Incentive Arrangements.

(a) VEC Stock Plans. VEC shall effect appropriate amendments to the Valero Energy Corporation 2003 Employee Stock Incentive Plan, the Valero Energy Corporation 2001 Executive Stock Incentive Plan, 1997 Stock Option Plan and the Ultramar Diamond Shamrock Corporation Amended and Restated 1996 Long Term Incentive Plan (the “VEC Stock Plans”) such that, for purposes of administering the outstanding awards previously made to individuals who are Eligible GP Employees as of the Second Tranche: (i) such employees shall be deemed to have terminated employment as of the Second Tranche; and (ii) all such awards shall become fully vested as of the Second Tranche, and exercisable

over the succeeding 12-month period. All costs, expenses and liabilities associated with or arising from VEC’s obligations under this paragraph 10(a) shall be the responsibility of VEC. VEC hereby agrees to accelerate the vesting of any outstanding award under the VEC Stock Plans held by an individual who becomes an Eligible GP Employee after the Second Tranche, such acceleration to occur immediately prior to the applicable Cut-Over Date. VEC further agrees to effect appropriate amendments to the VEC Stock Plans to provide for such acceleration and to extend the exercise period for options outstanding as of the Cut-Over Date to the end of the calendar year in which the Cut-Over Date occurs, provided however, that Post-Second Tranche Eligible GP Employees whose Cut-Over Date is during the period of December 1, 2007 through December 31, 2007, shall have 12 months from the Cut-Over Date in which to exercise outstanding options. Notwithstanding the foregoing, if the IRS gives further relief under Section 409A of the Code prior to the expiration of an exercise period for an Eligible GP Employee that would permit further extension of the exercise period, VEC agrees to extend as permitted but not beyond 12 months from the Cut-Over Date.

(b) GP Unit Plans. GP shall continue to sponsor and administer the Xxxxxx XX, LLC Amended and Restated 2000 Long-Term Incentive Plan, the Xxxxxx XX, LLC Amended and Restated 2002 Unit Option Plan and the Xxxxxx XX, LLC Amended and Restated 2003 Employee Unit Incentive Plan (the “GP Unit Plans”), in accordance with their terms and conditions, as they may be amended from time to time. GP shall effect appropriate amendments to the GP Unit Plans such that, for purposes of administering the outstanding awards previously made to VEC Employees (i) such employees shall be deemed to have terminated employment with respect to GP as of the Second Tranche; and (ii) all such awards shall become fully vested as of the Second Tranche, and exercisable over the succeeding 12-month period. All costs, expenses and liabilities associated with or arising from GP’s obligations under this paragraph 10(b) shall be the responsibility of GP.

11. Nonqualified Deferred Compensation Arrangements.

(a) Valero Energy Corporation Deferred Compensation Plan. Under the terms of the Valero Energy Corporation Deferred Compensation Plan (“Deferred Compensation Plan”), Eligible GP Employees who are participants in the Deferred Compensation Plan shall be deemed to have terminated employment upon VEC ceasing to own a majority of the equity interest in GP. As provided for under the Deferred Compensation Plan, the account balances of such Eligible GP Employees shall be distributed in accordance with the deferral and distribution elections previously made by such Eligible GP Employees consistent with the provisions of the Deferred Compensation Plan.

(b) Excess Thrift Plan. Effective as of July 1, 2006, GP shall adopt an Excess Thrift Plan (“GP Excess Thrift Plan”) for Eligible GP Employees, as well as other individuals subsequently employed by GP and determined to be eligible under the

terms of the GP Excess Thrift Plan, which shall have initial terms substantially similar to the terms of the Valero Energy Corporation Excess Thrift Plan (“VEC Excess Thrift Plan”). Eligible GP Employees shall cease to be eligible for additional contributions or accruals under the VEC Excess Thrift Plan effective as of July 1, 2006 or the Cut-Over Date, as applicable, and, in accordance with the terms of the VEC Excess Thrift Plan, all benefits accrued as of such date by Eligible GP Employees shall be distributed to such Eligible GP Employees as soon as reasonably practical following the effective date of the Initial Tranche or the Cut-Over Date, if later, considering, without limitation, restrictions on certain distributions imposed by the Code. The GP Excess Thrift Plan shall provide credit to all Eligible GP Employees for purposes of vesting for all service credited by VEC for such purpose under the VEC Excess Thrift Plan.

(c) Frozen Nonqualified 401(k) Plan for Former UDS Employees. Effective as of July 1, 2006, the Ultramar Diamond Shamrock Corporation Nonqualified 401(k) Plan (the “VEC UDS Plan”), which is maintained as a frozen nonqualified deferred compensation plan covering certain former employees of Ultramar Diamond Shamrock Corporation, shall be effectively split into two plans, the VEC UDS Plan and the Xxxxxx XX, LLC Frozen Nonqualified 401(k) Plan for Former Employees of Ultramar Diamond Shamrock Corporation (the “GP UDS Plan”). The remaining VEC UDS Plan shall continue to be sponsored, maintained, and administered by VEC, and the spun-off GP UDS Plan shall be sponsored, maintained, and administered by GP. All Eligible GP Employees who are participants in the VEC UDS Plan shall automatically become participants in the GP UDS Plan effective as of July 1, 2006 or the Cut-Over Date, as applicable, and they shall, effective as of such date, cease their eligibility for and participation in the VEC UDS Plan in accordance with its terms as amended from time to time. All VEC Employees who are participating in the VEC UDS Plan shall continue to participate in such plan, in accordance with its terms as amended from time to time.

(d) Excess Pension Plan and Supplemental Retirement Plan. Effective as of July 1, 2006, GP shall adopt an Excess Pension Plan (“GP Excess Pension Plan”) and a Supplemental Retirement Plan (“GP SERP”) for Eligible GP Employees, as well as other individuals subsequently employed by GP and determined to be eligible under the terms of the GP Excess Pension Plan or GP SERP, which shall have initial terms substantially similar to the terms of the corresponding VEC plans (“VEC Excess Pension Plan” and “VEC SERP”, respectively). Eligible GP Employees who, as of July 1, 2006 or the Cut-Over Date, as applicable, are participants in the VEC Excess Pension Plan or the VEC SERP shall, as of such date, automatically become participants in the GP Excess Pension Plan or the GP SERP, as the case may be, and shall cease to be eligible to participate in, or to receive additional accruals under, the VEC Excess Pension Plan or the VEC SERP. Upon the transfer of assets and liabilities described in paragraph 13 below as of the effective date of the initial tranche, GP shall be solely obligated with respect to all excess pension and supplemental retirement benefits of Eligible

GP Employees, and VEC shall have no further liabilities with respect to such benefits.

12. Determination Letter Application; Filings. VEC shall assist GP in preparing, submitting and processing determination letter applications with the IRS for the GP Pension Plan and the XX Xxxxxx Plan, seeking determinations that such plans and their underlying trusts meet the qualification requirements of Code section 401(a). Additionally, VEC shall assist GP in preparing and making any and all other governmental filings, whether with the DOL, IRS or otherwise, as the parties may deem appropriate with respect to the adoption of the GP Plans. All costs and expenses incurred by VEC or GP pursuant to this paragraph shall be for VEC’s account.

13. Transfer of Liabilities and Associated Assets. The parties hereto agree that the liabilities described in Exhibit A attached hereto and incorporated herein shall be transferred to Holdings. Additionally, the assets described on Exhibit A shall be transferred to Holdings by VEC or certain VEC Subsidiaries.

14. Tax Deduction Agreement. In connection with the transfer of liabilities and assets described in paragraph 13 above and in order to simplify the ongoing administrative effort required by all parties in connection with this Agreement, VEC and Holdings agree that the entire tax deduction related to long-term incentive plans of Holdings and GP, as applicable, will be deductible by Holdings and GP, as applicable, and that the entire tax deduction related to stock options and restricted stock of VEC will be deductible by VEC.

15. Responsibility for Own Plans; Limitation of Liability. VEC makes no (and hereby disclaims and negates any and all) representations and warranties, express or implied, with respect to the assistance provided to GP in the design of the employee benefit plans established by GP as contemplated herein and with respect to the plans themselves, including without limitation qualification of such plans under relevant provisions of the Code, and shall have no liability with respect to such design. GP acknowledges and accepts full responsibility for the design of its own employee benefit plans, and acknowledges that the decisions made with respect to the design of each employee benefit plan contemplated by this Agreement is GP’s sole responsibility as sponsor of such plan, as evidenced by the actions of its Board of Directors and its Benefit Plans Administrative Committee.

GP acknowledges (1) that this Agreement does not address the implementation, or the ongoing maintenance or administration of such plans, (2) that to the extent that any subsidiary or affiliate of VEC provides assistance with respect to implementation, or ongoing maintenance or administration with regard to any of such plans, such implementation, maintenance or administration shall be performed pursuant to the Services Agreement and subject to the terms thereof, or such other written agreement between the parties as may be in force at the time such implementation, maintenance or administration is performed, and (3) that VEC shall have no liability pursuant to this

Agreement with respect to any implementation, maintenance or administration of such plans.

16. Confidentiality. Each of the parties agrees to treat, and to cause its affiliates, employees and agents to treat, all records and other information with respect to the other party in confidence and in compliance with all applicable laws regarding confidentiality and privacy.

17. Notices. All communications, notices and disclosures required or permitted by this Agreement shall be in writing and shall be deemed to have been given at the earlier of the date (a) when delivered personally or by messenger or by overnight delivery service by a recognized commercial carrier to an officer of the other party, (b) three days after being mailed by registered or certified United States mail, postage prepaid, return receipt requested, or (c) when received via facsimile or electronic mail, in all cases addressed to the individual for whom it is intended at his address set forth below or to such other address as a party shall have designated by notice in writing to the other party in the manner provided by this Section 17:
