In addition, and notwithstanding anything to the contrary herein, this Agreement does not supersede, amend or waive any rights or claims or causes of action Employee may have under any retirement plan, including without limitation the Valero Energy Corporation Pension Plan, Supplemental Executive Retirement Plan, health or dental plan, any Restricted Stock Agreement, the Valero Energy Corporation 2011 Omnibus Stock Incentive Plan, or any rights Employee may have as a Valero shareholder.

Neither the payment of any Consideration nor any agreements made or referenced in this Agreement are to be understood as an admission of wrongdoing or liability by the Company.

Employee agrees to cooperate with the Company and its representatives, as reasonably requested by the Company, by responding to questions, attending meetings, depositions, administrative proceedings and court hearings, executing documents and cooperating with the Company and its legal counsel with respect to business issues and/or claims and litigation of which Employee has personal or corporate knowledge as long as such cooperation does not unreasonably interfere with Employee’s responsibility with or to a subsequent employer. It shall be the sole responsibility of the Company, or its representative, to identify and request of me the specific tasks, meetings, communications or involvement in similar activities for which the Company seeks Employee’s cooperation. Employee is not authorized to unilaterally undertake such activities without request by the Company or its representative, and is, in fact, expressly prohibited from doing so. Employee agrees to communicate with any party adverse to the Company, or with a representative, agent or legal counsel for any such party, concerning any such pending or future claims or litigation or administrative hearing solely through legal counsel for the Company. The Company also agrees to pay all my reasonable expenses incurred at the Company’s request while providing assistance to the Company in connection with the terms of this Section. The payments to be made to me under this Agreement are in part in consideration for Employee’s agreement to provide occasional, de minimis cooperation with the Company in connection with the requirements set forth herein. In the event that Employee’s cooperation is requested for more than a de minimis time commitment, the Company will compensate Employee for the time she reasonably and actually spends at the Company’s request at a rate equal to $370/hour. In the event that Employee reasonably deems it in her interest to retain personal legal counsel in conjunction with a legal matter about which the Company seeks her cooperation, the Company agrees to pay for the reasonable fees incurred by Employee in connection with such representation.

Employee understands this Agreement is confidential, and agrees she has not, may not, and will not disclose the existence or terms of this Agreement (including any amounts paid in consideration of this Agreement) to any third party, except that Employee may disclose the terms of this Agreement to Employee’s spouse, personal attorney, accountant, wealth management advisor, and tax advisor, provided Employee instructs such person that the information is confidential and not to be disclosed.

Employee and the Company agree not to, directly or indirectly, engage in communications or conduct that disparages the other (including disparagement by Employee of the Company’s officers, directors, representatives, or employees to the extent that such statement

3

refers to such individual’s work for or association with the Company). Employee and the Company further agree not to make any negative statements about the business, products, employees, work performance or employment/compensation /benefit practices of the other. Nothing in this Agreement shall be construed to prevent Employee from filing a Charge of Discrimination with the Equal Employment Opportunity Commission or other federal, state or local agency, or from participating in any manner in an investigation or proceeding with the Equal Employment Opportunity Commission or other federal, state or local agency, although Employee agrees that Employee is not entitled to recover any damages, costs, fees or other personal relief from the Company in any such proceeding.

Further, Employee understands nothing in this Agreement prohibits Employee from reporting possible violations of federal, state or local law or regulation to any governmental agency or entity, including but not limited to the Department of Justice, the Securities and Exchange Commission, the Congress, and any agency Inspector General, or making other disclosures that are protected under the whistleblower provisions of federal, state or local law or regulation. Employee does not need the prior authorization of the Company to make any such reports or disclosures and is not required to notify the Company that Employee has made such reports or disclosures.

Employee agrees that as an employee of the Company, Employee had access to and may have become informed of confidential, proprietary, and trade secret information of the Company. Employee agrees to keep in strict confidence and not directly or indirectly disclose or use any confidential, proprietary, or trade secret information of the Company unless required by law or court order.

As of my Retirement Date, Employee will have returned all Company property (keys, credit cards, identifications, computers, etc.) and information, including manuals or other materials created by the Company, any related company or entity, or any customer, which directly or indirectly relates to the business of the Company.

NOTICE: COMPANY HEREBY ADVISES EMPLOYEE, IN WRITING, TO CONSULT WITH AN ATTORNEY PRIOR TO EXECUTING THIS AGREEMENT.

I have been advised to consult with an attorney prior to executing this Agreement. In signing this Agreement, I have relied on my own judgment and/or the advice of my attorney, and not on any statement or representation of the Company. I understand the terms and conditions of this Agreement, agree to abide by it, and voluntarily execute it without any reservation. I understand this Agreement is a full and final release of any and all claims that I may have against the Company, outlined in the Section 3 above.

4

I represent I have not assigned, pledged, sold, transferred, or otherwise conveyed any right, claim, or interest that I may have in any matters released herein.

I agree and understand that any disputes arising out of this Agreement shall be resolved using the Company’s Dialogue Dispute Resolution Program (“Dialogue”), which includes binding arbitration.

The validity, construction, interpretation, and administration of this Agreement shall be controlled and governed by the substantive laws of the State of Texas.

I agree that if any provision of this Agreement is declared invalid or unenforceable by a court of competent jurisdiction or by an arbitrator in a proceeding under Dialogue, then such provision will be modified only to the extent necessary to cure such invalidity, with a view to enforcing the parties’ intention as set forth in this Agreement to the extent permissible. All remaining provisions of this Agreement shall not be affected thereby and shall remain in full force and effect.

This Agreement is intended to comply, and shall be administered consistently in all respects, with Section 409A of the Internal Revenue Code of 1986, as amended (“Code”), and any regulations and additional guidance promulgated thereunder, to the extent applicable. In this connection, Valero shall have authority to take any action, or refrain from taking any action, with respect to this Agreement that is reasonably necessary to ensure compliance with Code Section 409A (provided that Valero shall choose the action that best preserves the value of the payments and benefits provided to me under this Agreement that is consistent with Code Section 409A), and the parties agree that this Agreement shall be interpreted in a manner that is consistent with Code Section 409A. In furtherance, but not in limitation of the foregoing: (a) in no event may I designate, directly or indirectly, the calendar year of any payment to be made hereunder; (b) as I am a “specified employee” within the meaning of Code Section 409A, payments which constitute a “deferral of compensation” under Code Section 409A and which would otherwise become due during the first six (6) months following my separation of employment shall be delayed and all such delayed payments shall be paid in full in the seventh (7^th) month after the Retirement Date, provided that the above delay shall not apply to any payment that is excepted from coverage by Code Section 409A, such as a payment covered by the short-term deferral exception described in Treasury Regulations Section 1.409A-1(b)(4); (c) notwithstanding any other provision of this Agreement, my termination, resignation or retirement of my employment hereunder, shall mean, and be interpreted consistent with, a “separation from service” within the meaning of Code Section 409A, and “Retirement Date”, or similar terms, for purposes of determining the date that any payment or benefit is required to be provided hereunder, shall be deemed to mean the date of my separation from service within the

5

meaning of Code Section 409A; and (d) with respect to any reimbursement of fees and expenses, or similar payments, including gross-up payments, or any in-kind benefits, the following shall apply: (i) the amount of expenses eligible for reimbursement hereunder, or in-kind benefits to which I am entitled hereunder, in any particular year shall not affect the expenses eligible for reimbursement or in-kind benefits in any other year; (ii) the right to reimbursement of expenses or in-kind benefits shall not be subject to liquidation or exchange for any other benefit; and (iii) the reimbursement of an eligible expense or a payment shall be made on or before the last day of the calendar year following the calendar year in which the expense was incurred or the payment was remitted, as the case may be.

Employee agrees this Agreement constitutes the entire agreement, covenant, and consideration with the Company related to the subject matter. By way of clarification and not limitation, and notwithstanding anything to the contrary herein, this Agreement does not supersede, replace, amend or waive any rights or claims or causes of action Employee may have under any insurance policy or coverage or any agreement of indemnity, defense, or fee or cost advancement arising from or related in any way to Employee’s service as an officer, director, manager, or employee of Valero or any Valero Releasee. In addition, and notwithstanding anything to the contrary herein, this Agreement does not supersede, amend or waive any rights Employee may have under any retirement plan, including without limitation the Valero Energy Corporation Pension Plan, health or dental plan, any Restricted Stock Agreement, the Valero Energy Corporation 2011 Omnibus Stock Incentive Plan, the Valero Energy Corporation Supplemental Executive Retirement Plan, or any rights Employee may have as a Valero shareholder. Employee has not relied upon any other consideration, covenant, promise, or agreement not contained in this document.
