 (ii) any and all immigration-related, visa, work application or similar
rights, obligations and Liabilities related to any Corner Store Group Employees; and 
 (iii) except as
expressly provided in the Separation Agreement, any and all Liabilities and obligations whatsoever with respect to claims made by or on behalf of Corner Store Group Employees in connection with any employee benefit plan, program or policy not
retained or assumed by any Valero Entity pursuant to this Agreement, the Separation Agreement or any Ancillary Agreement, including any such Liabilities relating to actions or omissions of or by any Corner Store Entity or any officer, director,

 (c) Notwithstanding the foregoing provisions of this Section 1.1(a): 

(i) if a Corner Store Group Employee becomes an employee of the Valero Group after the Distribution Date, the
indemnification obligations of Corner Store in Section 1.1(a), as they relate to such Employee, shall only apply to Liabilities arising prior to such individual becoming an employee of the Valero Group after the Distribution Date; and

Distribution Date. 
 Section 1.2 Service Credit. 

(a) Service for Eligibility, Vesting, and Benefit Purposes. Except as otherwise provided in any other provision of this
Agreement, from and after the Distribution Date through August 31, 2013, the Corner Store Benefit Plans shall, and Corner Store shall cause each Corner Store Entity to, recognize each Corner Store Group Employee’s and Post Distribution
Transferred Employee’s full service with any Valero Entity, to the same extent such service would be credited if it had been performed for a Corner Store Entity, solely for purposes of eligibility, vesting and determination of level of benefits
under any such Corner Store Benefit Plan. 
 (b) Evidence of Prior Service. Notwithstanding anything to the
contrary, but subject to applicable Law, upon reasonable request by either Party (the “Requesting Party”), the other Party (the “Providing Party”) will provide to the Requesting Party copies of any records available

obtain any missing data for purposes of determining benefit eligibility, participation, vesting and calculation of benefits with respect to any such Employee. 
 Section 1.3 Transition Services. The Parties acknowledge that the Valero Group or the Corner Store Group may provide administrative services for certain of the other Party’s benefit
programs for a transitional period under the terms of the Transition Services Agreements. The Parties agree to enter into a business associate agreement (if required by HIPAA or other applicable health information privacy Laws) in connection with
such Transition Services Agreements.

anything to the contrary in this Agreement, the Separation Agreement or any Ancillary Agreement, no participant in the Corner Store 401(k) Plan, Corner Store Welfare Plans or other Corner Store Benefit Plans shall receive benefits to the extent that
receipt of such benefits would result in duplication of benefits provided by the corresponding Valero Benefit Plan or arrangement. Furthermore, unless expressly provided for in this Agreement, the Separation Agreement or in

Adjusted Valero Option shall be equal to the product of (i) the per-share exercise price of the corresponding Valero Option immediately prior to the Distribution Date multiplied by (ii) the Valero Price Ratio, rounded up to the nearest
whole hundredth of a cent (the “Valero Adjusted Exercise Price”); and 
 (b) the number of shares of Valero
Common Stock subject to each such Adjusted Valero Option shall be equal to the product of (i) the number of shares of Valero Common Stock subject to the corresponding Valero Option immediately prior to the Distribution Date multiplied by
(ii) the Valero Share Ratio, with any fractional share rounded down to the nearest whole share. 

  
 10 









 Section 4.2 Restricted Stock Awards. Each Valero RSA outstanding as of the
Distribution Date shall be adjusted by multiplying the number of shares of Valero Common Stock subject to such Valero RSA by the Valero Share Ratio (each such adjusted Valero RSA, an “Adjusted Valero RSA”). If the resulting product
includes a fractional share, the number of shares of Valero Common Stock subject to such Adjusted Valero RSA shall be rounded to the nearest whole share. Each Adjusted Valero RSA shall be subject to the same terms and conditions after the
Distribution Date as the terms and conditions applicable to the corresponding Valero RSA immediately prior to the Distribution Date. Each Valero RSA that is held by a Corner Store Group Employee shall become vested as of immediately prior to the
Record Date, and each Valero RSA that is held by a Post Distribution Transferred Employee shall become vested as of immediately prior to the Transfer Date. 
 Section 4.3 Performance Share Awards. Each Valero PSA outstanding as of the Distribution Date shall be adjusted by multiplying the number of shares of Valero Common Stock subject to such
Valero PSA by the Valero Share Ratio (each such adjusted Valero PSA, an “Adjusted Valero PSA”). If the resulting product includes a fractional share, the number of shares of Valero Common Stock subject to such Adjusted Valero PSA
shall be rounded to the nearest whole share. Each Adjusted Valero PSA shall be adjusted to reflect the change in value to Valero Common Stock after the Distribution Date; provided, however, that, with respect to any Valero PSA held by
a Corner Store Group Employee, continued employment by the Corner Store Group shall not be treated as continued employment with the Valero Group in the case of any Valero PSA held by a Corner Store Group Employee and, therefore, all Valero PSA held
by a Corner Store Group Employee on the Distribution Date shall be forfeited. 
 Section 4.4 Liabilities for Settlement
of Awards. 
 (a) Settlement of Valero Options. Valero shall be responsible for all Liabilities associated
with Valero Options (regardless of the holder of such awards) including any option exercise, share delivery, registration or other obligations related to the exercise of the Valero Options. 

  
 11 









 (b) Settlement of Valero RSAs. Valero shall be responsible for all Liabilities
associated with Valero RSAs including any share delivery, registration or other obligations related to the settlement of the Valero Restricted Stock awards. 
 (c) Settlement of Outstanding Valero PSAs. Valero shall be responsible for all Liabilities associated with Valero PSAs, including any share delivery, registration or other obligations
related to the settlement of Valero PSAs. 
 Section 4.5 Bonus and Incentive Payments. For the avoidance of doubt,
(i) the Valero Group shall be solely responsible for funding, paying, and discharging all obligations relating to any annual cash incentive awards that any Valero Group Employee is eligible to receive under any Valero annual bonus plans with
respect to payments made beginning, at or after the Distribution Date, and no Corner Store Entity shall have any obligations with respect thereto, and (ii) the Corner Store Group shall be solely responsible for funding, paying, and discharging
all obligations relating to any annual cash incentive awards that any Corner Store Group Employee or Post Distribution Transferred Employee is eligible to receive under any Corner Store Group annual bonus and other short-term incentive compensation
plans with respect to payments made beginning at or after the Distribution Date, and no Valero Entity shall have any obligations with respect thereto; provided; however, as of no later than 30 days following the Distribution Date or Transfer Date,
as applicable, the Valero Group shall make a cash payment based upon one-hundred percent (100%) of bonus target for the period of time of participation from January 1, 2013 to the time immediately prior to the Distribution Date or Transfer
Date, as applicable, to the Corner Store Group in respect of bonuses accrued in respect of Corner Store Group Employees or Post Distribution Employees under the Valero Energy Corporation Annual Bonus Plan and the Valero Energy Corporation Annual
Incentive Plan for Named Executive Officers as of the Distribution Date or Transfer Date, as applicable. Such prorated cash payment will not be subject to future adjustment. 
 Section 4.6 Tax Reporting and Withholding for Equity-Based Awards. Valero (or one of its Subsidiaries) shall be responsible for (a) all income, payroll, or other tax reporting related to
income of Employees from awards in respect of Valero Common Stock, and (b) remitting applicable tax withholdings for such income to each applicable taxing authority; it being understood that in taking such actions Valero shall be acting as
agent for Corner Store. Notwithstanding the foregoing, the terms of this Section 4.6 shall not limit any obligations of Valero or Corner Store with respect to the subject matter hereof under the Transition Services Agreements. Valero and
Corner Store acknowledge and agree that the Parties shall cooperate with each other and with third-party providers to effectuate withholding and remittance of taxes, as well as required tax reporting, in a timely, efficient, and appropriate manner.

 Section 6.2 Participation; Distributions. The Nonqualified Plan Participants shall cease accruing benefits under
the Nonqualified Plans as of the Distribution Date or Transfer Date, as applicable. Valero and Corner Store acknowledge that none of the transactions contemplated by the Separation Agreement or any Ancillary Agreement will trigger a payment or

 ARTICLE VII 
 WELFARE PLANS 

Section 7.1 Transition Period; Establishment of Corner Store Welfare Plans. In accordance with the terms of the Transition
Services Agreements, from the Distribution Date until January 1, 2014 (the “Transition Date”), the Corner Store Entities will be included as participating employers to the Valero Welfare Plans set forth on Exhibit A. On
or prior to the Transition Date, Corner Store shall, or shall cause another Corner Store Entity to, establish and adopt Corner Store Welfare Plans which will provide welfare benefits to each Corner Store Group Employee or Post Distribution
Transferred Employee who is transferred from the Valero Group to the Corner Store Group who is a participant in any of the Valero Welfare Plans (and their eligible spouses and dependents, as the case may be) (collectively, the “Corner Store
Welfare Plan Participants”). Coverage and benefits under the Corner Store Welfare Plans shall then be provided to the Corner Store Welfare Plan Participants on an uninterrupted basis under the newly established Corner Store Welfare Plans.
Corner Store Welfare Plan Participants shall cease to be eligible for coverage under the Valero Welfare Plans at the Transition Date. 
 Section 7.2 Transitional Matters Under Corner Store Welfare Plans. 

(a) Treatment of Claims Incurred. 
 (i) Liability for Claims. With respect to unpaid covered claims incurred prior to the Distribution Date or Transfer Date, as applicable, by any Corner Store Welfare Plan Participant under
any Valero Welfare Plans, including claims that are self-insured and claims that are fully insured through third-party insurance, Valero shall retain and be responsible for the payment for such claims or shall cause such Valero Welfare Plans to
fully perform, pay and discharge all such claims, as the case may be, and except as provided in Section 7.2(a)(iv), no Corner Store Entity shall be responsible for any Liability with respect to any such claims. Claims incurred by Corner Store
Welfare Plan Participants from the Distribution Date through the Transition Date shall be governed by the terms of the Transition Services Agreements. 
 (ii) Claims Incurred. For purposes of this Section 7.2(a), a claim or expense is deemed to be incurred (A) with respect to medical (including continuous hospitalization), dental,
vision and/or prescription drug benefits, upon the rendering of health services giving rise to such claim or expense; (B) with respect to life 

  
 15 









 
insurance, accidental death and dismemberment and business travel accident insurance, upon the occurrence of the event giving rise to such claim or expense; and (C) with respect to short-
and long-term disability benefits, upon the date of an individual’s disability, as determined by the disability benefit insurance carrier or claim administrator, giving rise to such claim or expense. 

(iii) Long Term Disability Benefits. Employees of the Corner Store Group who are receiving Long Term
Disability (“LTD”) benefits immediately prior to the Distribution Date shall have their employment transferred to a Valero Entity effective immediately prior to the Distribution Date and shall be Valero Group Employees for all
purposes of this Agreement. If any such Employee is released to return to work or becomes no longer entitled to receive LTD benefits on or after the Distribution Date, and provided that Corner Store is notified of such fact, Corner Store agrees to
consider if there are any positions within the Corner Store Group for which such Employee may be qualified, but Corner Store shall have no obligation to hire such Employee. 

(iv) Short Term Disability Benefits. With respect to those Corner Store Group Employees who are receiving
Short Term Disability (“STD”) benefits immediately prior to the Distribution Date, or Post Distribution Transferred Employees who are receiving STD benefits immediately prior to the applicable Transfer Date, Corner Store will be
responsible for continuing to provide such benefits until such time as those STD benefits terminate in accordance with the terms of the Valero STD plan (subject to the relevant provisions of the Transition Services Agreement pursuant to which a
Valero Entity will administer such benefits for Corner Store up to the Transition Date). In the event any such Corner Store Group Employee, after the Distribution Date, or Post Distribution Transferred Employee, after the applicable Transfer Date,
becomes eligible to transition directly from receiving STD benefits to receiving LTD benefits, Valero will provide such LTD benefits but will not be obligated to provide any other employment-related benefits (including any other Welfare Plan
benefits) to such Corner Store Group Employee or Post Distribution Transferred Employee. 
 (b) COBRA. The Valero
Group shall be responsible for the COBRA claims incurred by Employees (and their qualifying beneficiaries) prior to the Distribution Date, regardless of whether payments for such claims are made or due after the Transition Date. At and after the
Distribution Date, Corner Store shall assume all requirements under COBRA with respect to all Corner Store Group Employees or Post Distribution Transferred Employees (and their qualifying beneficiaries) who, as of the day prior to the Distribution
Date or Transfer Date, as applicable, were covered under a Valero Benefit Plan pursuant to COBRA or who have a COBRA qualifying event (as defined in Section 4980B of the Code) prior to the Distribution Date or Transfer Date. Notwithstanding the
foregoing, the terms of this Section 7.2(b) shall not limit any obligations of Valero or Corner Store with respect to the subject matter hereof under the Transition Services Agreements. 

(c) Retiree Medical. The Valero Group will provide retiree medical benefits to those Corner Store Group Employees or Post
Distribution Transferred Employees who are 

  
 16 









 
eligible for the Valero Group retiree medical benefits immediately prior to the Transition Date. The eligible Corner Store Group Employees and Post Distribution Transferred Employees will be
provided a one-time opportunity to enroll in the retiree medical benefits on the Transition Date in the retiree medical plan in effect as of the Transition Date. In the event a Corner Store Group Employee or Post Distribution Transferred Employee
does not enroll as of the Transition Date, such retiree medical benefits will be forfeited. 
 Section 7.3 Waiver of
Conditions or Restrictions. Unless prohibited by applicable Law, the Corner Store Welfare Plans will waive all limitations as to preexisting conditions, exclusions, service conditions, waiting period limitations or evidence of
insurability requirements that would otherwise be applicable to the Corner Store Welfare Plan Participant following the Transition Date to the extent that such Employee had previously satisfied such limitation under the corresponding Valero Welfare
Plan. 
 Section 7.4 Insurance Contracts. To the extent any Valero Welfare Plan is funded through the purchase of an
insurance contract or is subject to any stop loss contract, Valero and Corner Store will cooperate and use their commercially reasonable efforts to replicate such insurance contracts for Corner Store (except to the extent changes are required under
applicable state insurance Laws or filings by the respective insurers) and to maintain any pricing discounts or other preferential terms for both Valero and Corner Store for a reasonable term. Neither Party shall be liable for failure to obtain such
insurance contracts, pricing discounts, or other preferential terms for the other Party. Each Party shall be responsible for any new or additional premiums, charges, or administrative fees that such Party may incur with respect to its insurance
coverage pursuant to this Section 7.4. 
 Section 7.5 Third-Party Vendors. Except as provided below, to the
extent any Valero Welfare Plan is administered by a third-party vendor, Valero and Corner Store will cooperate and use their commercially reasonable efforts to replicate any contract with such third-party vendor for Corner Store and to maintain any
pricing discounts or other preferential terms for both Valero and Corner Store for a reasonable term. Neither Party shall be liable for failure to obtain such pricing discounts or other preferential terms for the other Party. Each Party shall be
responsible for any new or additional premiums, charges, or administrative fees that such Party may incur with respect to its contracts pursuant to this Section 7.5. 
 Section 7.6 Workers’ Compensation. With respect to claims for workers compensation in the United States, (a) the Valero Group shall be responsible for claims in respect of
(i) Valero Group Employees and Former Employees, whether occurring prior to, on or following the Distribution Date and (ii) Corner Store Group Employees occurring prior to the Distribution Date, and (b) the Corner Store Group shall be
responsible for all claims in respect of Corner Store Group Employees and Post Distribution Transferred Employees occurring on or following the Distribution Date or Transfer Date, respectively. For purposes of this Section 7.6, claims shall be
deemed to be incurred upon the occurrence of the injury giving rise to such claim.

binding upon the Parties and their respective successors and permitted assigns. Except as otherwise expressly provided in this Agreement, this Agreement is solely for the benefit of the Parties and should not be deemed to confer upon any third
parties any remedy, claim, Liability, reimbursement, cause of action, or other right in excess of those existing without reference to this Agreement. Nothing in this Agreement is intended to amend any employee benefit plan or affect the applicable
plan sponsor’s right to amend or terminate any employee benefit plan pursuant to the terms of such plan. The provisions of this Agreement are solely for the benefit of the Parties, and no current or former Employee, officer, director, or
independent contractor or any other individual associated therewith shall be regarded for any purpose as a third-party beneficiary of this Agreement. This Agreement may not be assigned by any Party, except with the prior written consent of the other
Parties. 
 Section 10.5 Amendment; Waivers. No change or amendment may be made to this Agreement except by an
instrument in writing signed on behalf of each of the Parties. Any Party may, at any time, (i) extend the time for the performance of any of the obligations or other acts 

  
 22 









 
of another Party, (ii) waive any inaccuracies in the representations and warranties of another Party contained herein or in any document delivered pursuant hereto, and (iii) waive
compliance by another Party with any of the agreements, covenants, or conditions contained herein. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the Party to be bound thereby. No failure or delay
on the part of any Party in the exercise of any right hereunder shall impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty, covenant, or agreement contained herein, nor shall any single
or partial exercise of any such right preclude other or further exercises thereof or of any other right. 
 Section 10.6
Remedies Cumulative. All rights and remedies existing under this Agreement or the Schedules attached hereto are cumulative to, and not exclusive of, any rights or remedies otherwise available. 

Section 10.7 Notices. Unless otherwise expressly provided herein, all notices, claims, certificates, requests, demands and
other communications hereunder shall be made or given in accordance with the provisions of Section 10.5 of the Separation Agreement. 
 Section 10.8 Counterparts. This Agreement, including the Schedules hereto and the other documents referred to herein, may be executed in multiple counterparts, each of which when executed
shall be deemed to be an original but all of which together shall constitute one and the same agreement. 
 Section 10.9
Severability. If any term or other provision of this Agreement or the Schedules attached hereto is determined by a non-appealable decision by a court, administrative agency, or arbitrator to be invalid, illegal, or incapable of being enforced
by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any
manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the court, administrative agency, or arbitrator shall interpret this Agreement so as to effect the
original intent of the Parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the fullest extent possible. If any sentence in this Agreement is so broad as to be unenforceable, the
provision shall be interpreted to be only so broad as is enforceable. 
 Section 10.10 Governing Law. This Agreement
(and any claims or disputes arising out of or related hereto or thereto or to the transactions contemplated hereby and thereby or to the inducement of any party to enter herein and therein, whether for breach of contract, tortious conduct, or
otherwise and whether predicated on common law, statute, or otherwise) shall be governed by and construed and interpreted in accordance with the Laws of the State of Texas, irrespective of the choice of laws principles of the State of Texas,
including all matters of validity, construction, effect, enforceability, performance, and remedies. 
 Section 10.11
Dispute Resolution. The dispute resolution procedures set forth in Article IV of the Separation Agreement shall apply to any dispute, controversy or claim (whether 

  
 23 









 
sounding in contract, tort or otherwise) that arises out of or relates to this Agreement, any breach or alleged breach hereof, the transactions contemplated hereby (including all actions taken in
furtherance of the transactions contemplated hereby on or prior to the date hereof), or the construction, interpretation, enforceability, or validity hereof. 
 Section 10.12 Performance. Each of Valero and Corner Store shall cause to be performed, and hereby guarantees the performance of, all actions, agreements and obligations set forth herein to be
performed by any Valero Entity and any Corner Store Entity, respectively. The Parties each agree to take such further actions and to execute, acknowledge, and deliver, or to cause to be executed, acknowledged, and delivered, all such further
documents as are reasonably requested by the other for carrying out the purposes of this Agreement or of any document delivered pursuant to this Agreement. 
 Section 10.13 Construction. This Agreement shall be construed as if jointly drafted by the Parties and no rule of construction or strict interpretation shall be applied against any Party.

 Section 10.14 Effect if Distribution Does Not Occur. Notwithstanding anything in this Agreement to the contrary,
if the Separation Agreement is terminated prior to the Distribution Date, this Agreement shall be of no further force and effect. 
 Section 10.15 Additional Indemnification Matters. THE RELEASES AND INDEMNIFICATION OBLIGATIONS OF THE PARTIES IN THIS AGREEMENT ARE EXPRESSLY INTENDED, AND SHALL OPERATE AND BE
CONSTRUED, TO APPLY EVEN WHERE THE LOSSES OR LIABILITIES FOR WHICH THE RELEASE AND/OR INDEMNITY ARE GIVEN ARE CAUSED, IN WHOLE OR IN PART, BY THE SOLE, JOINT, JOINT AND SEVERAL, CONCURRENT, CONTRIBUTORY, ACTIVE OR PASSIVE NEGLIGENCE OR THE STRICT
LIABILITY OR FAULT OF THE PARTY BEING RELEASED OR INDEMNIFIED.
