Exhibit 10.18
PERFORMANCE SHARE AGREEMENT

This Performance Share Agreement (the “Agreement”) is entered into as of _____,
20__, by and between Valero Energy Corporation, a Delaware corporation
(“Valero”), and __________, a participant (the “Participant”) in Valero’s 2011
Omnibus Stock Incentive Plan (as may be amended, the “Plan”), pursuant to and
subject to the provisions of the Plan.

1.
Grant of Performance Shares. Valero hereby grants to Participant _______
Performance Shares pursuant to Section 6.7 of the Plan. The Performance Shares
represent rights to receive shares of Common Stock of Valero, subject to the
terms and conditions of this Agreement and the Plan.

2.
Vesting and Delivery of Shares.

A.
Vesting. The Performance Shares granted hereunder shall vest over a period of
three years in equal, one-third increments with the first increment vesting on
the date of the regularly scheduled meeting of the Board’s Compensation
Committee in January 2019, and the second and third increments vesting on the
Committee’s meeting dates in January 2020 and January 2021, respectively (each
of these vesting dates is referred to as a “Normal Vesting Date”); any award(s)
of shares of Common Stock resulting in connection with such vesting shall be
subject to verification of attainment of the Performance Objectives described in
Section 4 below by the Compensation Committee. If the Committee is unable to
meet in January of a given year, then the Normal Vesting Date for that year will
be the date not later than March 31 of that year as selected by the Compensation
Committee.

B.
Rights. Until shares of Common Stock are actually issued to Participant (or his
or her estate) in settlement of the Performance Shares, neither Participant nor
any person claiming by, through or under Participant shall have any rights as a
stockholder of Valero (including, without limitation, voting rights or any right
to receive dividends or other distributions) with respect to such shares.

C.
Distribution. Any shares of Common Stock to be distributed under the terms of
this Agreement shall be distributed as soon as administratively practicable
after Performance Objectives described in Section 4 below have been verified by
the Compensation Committee, but not later than two-and-one-half months following
the end of the year in which such verification occurred.

3.
Performance Period. Except as provided below with respect to a Change of Control
(as defined in the Plan), the “Performance Period” for any Performance Shares
eligible to vest on any Normal Vesting Date shall be as follows:

A.
First Segment. The Performance Period for the first one-third vesting of
Performance Shares (those vesting on the Normal Vesting Date in January 2019)
shall be the calendar year ending on December 31, 2018.

B.
Second Segment. The Performance Period for the second one-third vesting of
Performance Shares (those vesting on the Normal Vesting Date in January 2020)
shall be the two calendar years ending December 31, 2019.

Page 1

--------------------------------------------------------------------------------

C.
Third Segment. The Performance Period for the final one-third vesting of
Performance Shares (those vesting on the Normal Vesting Date in January 2021)
shall be the three calendar years ending December 31, 2020.

4.
Performance Objectives.

A.
Total Shareholder Return. Total Shareholder Return (“TSR”) will be compiled for
a peer group of companies (the “Target Group”) for the Performance Period
immediately preceding each Normal Vesting Date. TSR for each such company is
measured by dividing (A) the sum of (i) the dividends on the common stock of
such company during the Performance Period, assuming dividend reinvestment, and
(ii) the difference between the average closing price of a share of such
company’s common stock for the 30 days of December 2 to December 31 at the end
of the Performance Period and the average closing price of such shares for the
30 days of December 2 to December 31 immediately prior to the beginning of the
Performance Period (appropriately adjusted for any stock dividend, stock split,
spin-off, merger or other similar corporate events), by (B) the average closing
price of a share of such company’s common stock for the 30 days of December 2 to
December 31 immediately prior to the beginning of the Performance Period.

B.
Target Group. The applicable Target Group shall be selected by the Compensation
Committee, acting in its sole discretion, each year not later than 90 days after
the commencement of the calendar year preceding each Normal Vesting Date. The
same Target Group shall be used to measure TSR with regard to all Performance
Shares vesting under all Performance Award Agreements of Valero having a similar
Normal Vesting Date.

C.
Performance Ranking and Award of Common Shares. For each Performance Period, the
TSR for Valero and each company in the Target Group shall be arranged by rank
from highest performer to lowest performer according to the TSR achieved by each
company. Shares of Common Stock will be awarded to Participant in accordance
with Valero’s percentile ranking within the Target Group. The number of shares
of Common Stock, if any, that Participant will be entitled to receive in
settlement of the vested Performance Shares will be determined on each Normal
Vesting Date and, subject to the provisions of the Plan and this Agreement, on
such Normal Vesting Date, the following percentage of the vested Performance
Shares will be awarded as shares of Common Stock to the Participant when
Valero’s TSR during the Performance Period falls within the following
percentiles (“Percentiles”):

Ranking
Percentile
Payout
1
100.0%
200.0%
2
88.9%
200.0%
3

--------------------------------------------------------------------------------

D.
Unearned Shares. Any Performance Shares not awarded as shares of Common Stock on
a Normal Vesting Date will expire and be forfeited; such Performance Shares may
not be carried forward for any additional Performance Period.

5.
Dividend Equivalent Award. In addition to the Performance Shares granted in
Section 1, the Participant is granted a Dividend Equivalent Award payable in
shares of Common Stock, as provided herein. On each Normal Vesting Date, the
amount of dividends paid to holders of Common Stock during the applicable
Performance Period shall be determined with respect to the Participant’s
Performance Shares that are vesting on that Normal Vesting Date—calculated as if
the Performance Shares were outstanding shares of Common Stock (the resulting
value being hereafter referred to as the “Target Dividend Equivalent Value”).
The Target Dividend Equivalent Value shall then be subject to further
calculation according to Valero’s TSR ranking during the Performance Period as
prescribed in Section 4.C. above (i.e., payout from 0% to 200% depending on
Valero’s TSR ranking). The number of shares of Common Stock payable to
Participant with respect to the Dividend Equivalent Award is equal to (x) the
Target Dividend Equivalent Value multiplied by the Performance Period’s payout
percentage calculated per Section 4.C., divided by (y) the Fair Market Value of
the Common Stock on the Normal Vesting Date (the resulting number being rounded
up to the nearest whole number of shares). See Exhibit A for an example of this
calculation.

6.
Termination of Employment.

A.
Voluntary Termination, Termination for “Cause,” and Early Retirement. If
Participant’s employment is

(i) voluntarily terminated by the Participant (other than through normal
retirement, death or disability), including termination in connection with
Participant’s voluntary early retirement (i.e., prior to age 62),
(ii) terminated by Valero for “cause” (as defined pursuant to the Plan),
then those Performance Shares that are outstanding and have not vested as of the
effective date of termination shall thereupon be forfeited.
B.
Retirement. If a Participant’s employment is terminated through his or her
normal retirement (i.e., age 62+ retirement), then any Performance Shares that
(i) have not theretofore vested or been forfeited, and (ii) were granted at
least one year prior to the Participant’s effective date of retirement, shall
continue to remain outstanding and shall vest on the Normal Vesting Dates
according to their original vesting schedule.

But any outstanding Performance Shares that were granted within one year of the
Participant’s effective date of retirement shall be prorated as follows. The
outstanding Performance Shares shall be prorated based on the number of months
worked from the date of grant to the Participant’s retirement date (rounding
upward), and the prorated number of Performance Shares shall thereafter vest on
the Normal Vesting Dates according to their original vesting schedule. Example:
•
25,530 Performance Shares granted on November 1, 2017,

•
normal retirement date of Participant is effective April 15, 2018,

•
working period is calculated as 6 months (5 full months plus partial month
rounding upward to 6 months),

•
original grant is adjusted by 6/12ths (50%) resulting in 12,765 Performance
Shares to vest according to their original vesting schedule.

--------------------------------------------------------------------------------

C.
Death, Disability, Involuntary Termination Other Than for “Cause,” and Change of
Control. If a Participant’s employment is terminated (i) through death or
disability, or (ii) by Valero other than for cause (as determined pursuant to
the Plan), or (iii) as a result of a Change of Control (as described in the
Plan) (each of the foregoing is hereafter referred to as a “Trigger Date”), then
each Performance Period with respect to any Performance Shares that have not
vested or been forfeited shall be terminated effective as of such Trigger Date;
the TSR for Valero and for each company in the Target Group shall be determined
for each such shortened Performance Period and the percentage of Performance
Shares to be awarded as shares of Common Stock for each such shortened
Performance Period shall be determined in accordance with Section 4 and shall be
distributed as soon as administratively practicable thereafter.

(i)
For purposes of determining the number of Performance Shares to be received as
of any Trigger Date, the Target Group as most recently determined by the
Compensation Committee prior to the Trigger Date shall be used.

(ii)
If the Trigger Date is the result of a Change of Control, then the number of
shares of Common Stock to be awarded to the Participant shall be prorated
commensurate with the length of service of the Participant during each
Performance Period. See Exhibit B for an example of this calculation.

7.
Cash Payment Election. Effective on any Normal Vesting Date (or Trigger Date
under Section 6.C), the Participant (or the Participant’s estate under Section
6.C) may elect to receive up to 50% of the after-tax value of the aggregate
number of shares of Common Stock earned on such Normal Vesting Date (or Trigger
Date) in cash, with the remainder paid in shares of Common Stock. Example:

•
following the calculation of Valero’s performance against the Target Group for
the two-year performance period ending December 31, 2019, it is determined that
the Participant is entitled to receive 4,000 shares of Common Stock on the
Normal Vesting Date occurring in January 2020 (the “2020 Normal Vesting Date”),

•
the 4,000 shares have an aggregate tax value of $300,000 (4,000 shares times an
assumed $75 FMV per share on the 2020 Normal Vesting Date), and the Participant
has made a tax withholding election of 39.6%,

•
the after-tax value of the 4,000 shares of Common Stock awarded on the Normal
Vesting Date is $181,200 ($300,000 times 60.4%),

•
the Participant may elect to receive up to $90,600 ($181,200 times 50%) in cash
on the 2020 Normal Vesting Date.

8.
Plan Incorporated by Reference. The Plan is incorporated into this Agreement by
this reference and is made a part hereof for all purposes. Capitalized terms not
otherwise defined in this Agreement shall have the meaning specified in the
Plan.

9.
No Assignment. This Agreement and the Participant’s interest in the Performance
Shares granted by this Agreement are of a personal nature, and, except as
expressly permitted under the Plan, Participant’s rights with respect thereto
may not be sold, mortgaged, pledged, assigned, transferred, conveyed or disposed
of in any manner by Participant, except by an executor or beneficiary pursuant
to a will or pursuant to the laws of descent and distribution. Any such
attempted sale, mortgage, pledge, assignment, transfer, conveyance or
disposition is void, and Valero will not be bound thereby.

--------------------------------------------------------------------------------

10.
Integration. This Agreement constitutes the entire agreement of the parties
relating to the transactions contemplated hereby, and supersedes all provisions
and concepts contained in all prior contracts or agreements between the
Participant and Valero, including that certain Change of Control Severance
Agreement (“COC Agreement”) between Participant and Valero. For avoidance of
doubt, Participant acknowledges that in the context of a Change of Control of
Valero, the terms of this Agreement shall prevail over the terms of the COC
Agreement with respect to the vesting of the Performance Shares granted under
this Agreement.

11.
Successors. This Agreement shall be binding upon any successors of Valero and
upon the beneficiaries, legatees, heirs, administrators, executors, legal
representatives, successors and permitted assigns of Participant.

12.
Code Section 409A. 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 (the “Code”), and the regulations and
additional guidance promulgated thereunder to the extent applicable.
Accordingly, Valero shall have the 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 payments and benefits provided to
Participant 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 Participant designate, directly or indirectly, the calendar year
of any payment to be made hereunder;

(b)
to the extent the Participant is a “specified employee” within the meaning of
Code Section 409A, payments, if any, that constitute a “deferral of
compensation” under Code Section 409A and that would otherwise become due during
the first six months following Participant’s termination of employment shall be
delayed and all such delayed payments shall be paid in full in the seventh month
after such termination 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, a termination,
resignation or retirement of Participant’s employment hereunder shall mean and
be interpreted consistent with a “separation from service” within the meaning of
Code Section 409A;

(d)
terms defined in this section will have the meanings given such terms under
Section 409A if and to the extent required to comply with Section 409A.
Notwithstanding any other provision hereof, Valero makes no representations or
warranties and will have no liability to Participant or any other person if any
provision of or payment under this Agreement is determined to constitute
deferred compensation subject to Section 409A but does not satisfy the
conditions of Section 409A.

Exhibit A

Example of Potential Payout of Dividend Equivalent Award in Shares of Common
Stock
(per Section 5 of the Agreement)

Assumptions and Calculations (for illustration purposes only):

1.
Assume the Participant was granted 12,000 Performance Shares on November 1,
2017.

2.
Assume the Normal Vesting Date for the second segment of these Performance
Shares is January 22, 2020. On that date 4,000 Performance Shares (12,000 / 3 =
4,000) vest with respect to the two-year Performance Period ending December 31,
2019.

3.
Assume the cumulative amount of dividends paid to holders of Common Stock during
the Performance Period is $5.80 per share (determined as follows).

dividends paid in 1Q18
 
$0.70
2Q18
 
$0.70
3Q18
 
$0.70
4Q18

2Q19
 
$0.75
3Q19
 
$0.75
4Q19
 
$0.75
 
 
$5.80 per share

4.
The “Target Dividend Equivalent Value” is $23,200.00 (4,000 Performance Shares
vesting, multiplied by $5.80 accumulated dividends per share, equals
$23,200.00).

5.
Valero’s TSR ranking for the Performance Period is determined (per Section 4.C.)
to generate a payout of 142.9%.

6.
The Fair Market Value of the Common Stock on the vesting date is $72.00.

7.
Based on the foregoing, the total number of shares of Common Stock earned by the
Participant on the vesting date is 6,177. The calculation is illustrated below.

Exhibit B

Example of Potential Payout in a Change of Control Context
(per Section 6.C.(ii) of the Agreement)

Assumptions and Calculations (for illustration purposes only):

1.
Assume the Participant was granted 15,000 Performance Shares on November 1,
2017.

2.
Assume Participant’s employment is terminated on June 30, 2018 as a result of a
Change of Control.

3.
Per Section 6.C. of the Agreement, all Performance Periods for all segments
(First Segment, Second Segment, Third Segment (See Section 3)) are shortened to
end on June 30, 2018.

4.
As a result of the TSR calculations of Section 4.C., Valero is ranked in the
88.9 percentile for each shortened Performance Period, resulting in a 200%
payout of common shares in each instance.

5.
Payout of common shares to the Participant is prorated based on the
Participant’s length of service during the original Performance Periods.

First Segment calculation.
 
 
 
 
15,000 / 3 = 5,000 performance shares.
