under the

SUNOCO, INC. LONG-TERM PERFORMANCE ENHANCEMENT PLAN III

This Performance Share Unit Agreement (the “Agreement”), entered into as of
                    , (the “Agreement Date”), by and between Sunoco, Inc.
(“Sunoco”) and                     , an employee of Sunoco or one of its
Affiliates (the “Participant”);

W I T N E S S E T H:

WHEREAS, the Sunoco, Inc. Long-Term Performance Enhancement Plan III (the
“Plan”) is administered by a Committee (the “Committee”) appointed by Sunoco’s
Board of Directors, and the Committee has determined to grant to the
Participant, pursuant to the terms and conditions of the Plan, an award (the
“Award”) of Performance Share Units (“PSUs”), representing rights to receive
shares of Common Stock which are subject to a risk of forfeiture by the
Participant; and

WHEREAS, the Participant has determined to accept such Award.

NOW, THEREFORE, Sunoco and the Participant, each intending to be legally bound
hereby, agree as follows:

ARTICLE I

AWARD OF PERFORMANCE SHARE UNITS

 

1.1 Identifying Provisions. For purposes of this Agreement, the following terms
shall have the following respective meanings:

 

(a)    Participant:   

 

   (b)    Grant Date:   

 

   (c)    Number of PSUs:   

 

   (d)    Performance Period:   

See Section 1.4 of this Agreement

   (e)    Form of Payment (cash/stock):   

 

  

Any initially capitalized terms and phrases used in this Agreement but not
otherwise defined herein, shall have the respective meanings ascribed to them in
the Plan.

 

1.2 Award of PSUs. Subject to the terms and conditions of the Plan and this
Agreement, the Participant is hereby granted the number of PSUs set forth herein
at Section 1.1.

 

1.3 Dividend Equivalents. The Participant shall be entitled to receive payment
from Sunoco in an amount equal to each cash dividend (“Dividend Equivalent”)
payable subsequent to the Grant Date, just as though such Participant, on the
record date for payment of such dividend, had been the holder of record of
shares of Common Stock equal to the actual number of PSUs, if any, earned and
received by the Participant at the end of the Performance Period. Sunoco shall
establish a bookkeeping methodology to account for the Dividend Equivalents to
be credited to the Participant. The Dividend Equivalents will not bear interest.

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

1.4 Performance Period. The length of the applicable period during which the
applicable performance goals must be attained shall be [Month, Day, Year]
through [Month, Day, Year].

 

1.5 Performance Goals.

 

  (a) Exhibit A, attached hereto and made a part hereof, sets forth the
performance goals that will be applied to determine the amount of the award
earned pursuant to this Agreement. These performance goals may be modified by
the Committee during, and after the end of, the Performance Period to reflect
significant events that occur during the Performance Period; provided, however,
that no such modification may be made if it would cause an award intended to
meet the requirements of Section 162(m)(4)(C) of the Code to fail to meet such
requirements.

 

  (b) The number of PSUs and corresponding Dividend Equivalents earned will be
equal to the amounts awarded multiplied by the applicable Performance Factors.
However, the Committee has the discretion to reduce (but not increase) some or
all of the amount that would otherwise be payable as a result of the
satisfaction of the Performance Goals. In making this determination, the
Committee may take into account any such factor or factors it determines are
appropriate, including but not limited to Company, business unit or individual
performance.

 

1.6 Termination of Employment.

 

  (a) Death or Disability. Upon the occurrence of the Participant’s Employment
Termination Date prior to the end of the Performance Period by reason of death
or permanent disability (as determined by the Committee), a number of PSUs (and
any corresponding Dividend Equivalents) immediately shall vest equal to the
product of (1) number of PSUs at grant (representing target performance) and
(2) a fraction, the numerator of which shall be the number of full and partial
calendar months between the date of the beginning of the Performance Period for
the PSUs and the Participant’s Employment Termination Date, and the denominator
of which shall be the number of full and partial calendar months from the date
of the beginning of the Performance Period to the end of the Performance Period.
Settlement of vested PSUs (and any corresponding Dividend Equivalents) shall be
made in accordance with Section 1.7.

 

  (b) Qualifying Termination. Upon the occurrence of a Qualifying Termination,
all unvested PSUs granted pursuant to this Agreement (and all related Dividend
Equivalents) immediately shall vest in full based on target performance number
of PSUs at grant), and shall be settled in accordance with Section 1.7.

 

  (c) Other Termination of Employment. Except as otherwise provided in Sections
1.6(a) and (b) above, or as determined by the Committee, upon termination of the
Participant’s employment with Sunoco or one of its Affiliates prior to the end
of the applicable Performance Period, the Participant shall forfeit 100% of such
Participant’s PSUs, together with the related Dividend Equivalents, and the
Participant shall not be entitled to receive any Common Stock, cash or any
payment of any Dividend Equivalents regardless of the level of Performance Goals
achieved as of the Participant’s Employment Termination Date for the respective
Performance Periods.

 

1.7 Settlement of PSUs and Dividend Equivalents.

 

  (a) Timing of Settlement. Settlement in respect of vested PSUs and the
corresponding vested Dividend Equivalents shall be made within sixty calendar
days after the PSUs and the corresponding Dividend Equivalents vest.

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

  (b) Form of Settlement in respect of PSUs earned. Subject to Section 5.8 of
the Plan, payment for PSUs earned shall be made in shares of Common Stock. The
number of shares paid shall be equal to the number of Share Units earned. The
Participant may elect to reduce this amount by the number of shares of Common
Stock which have, on the date PSUs are settled, a Fair Market Value equal to the
applicable federal, state and local withholding tax due on the receipt of Common
Stock, in lieu of making a cash payment equal to the amount of such withholding
tax due.

 

  (c) Form of Settlement of Related Earned Dividend Equivalents. Vested Dividend
Equivalents shall be payable by Sunoco in cash.

 

1.8 Stock Ownership Policy.

 

  (a) This Section 1.8 shall cease to apply upon the occurrence of a Change in
Control. Notwithstanding anything to the contrary contained in this Agreement or
the Plan, and at the discretion of the Committee, if the Participant is subject
to minimum stock ownership guidelines (as established from time to time by the
Committee or Sunoco), but fails to meet the applicable personal ownership
requirement within the prescribed period, the Participant’s receipt of shares of
Common Stock pursuant to Section 1.6 shall be subject to the restrictions
contained in this Section 1.8 which shall remain in place until compliance with
such ownership guidelines is attained.

 

  (b) The number of shares subject to the restrictions shall be equal to the
total number of shares of Common Stock being distributed, minus the number of
shares of Common Stock used to pay applicable federal, state and local
withholding tax on the total payment in respect of PSUs.

 

  (c) Other than transfers to family members or trusts that are permitted in
accordance with the applicable stock ownership guidelines, and that will not
result in a reduction in the level of ownership attributable to the Participant
under such guidelines, the Participant shall be prohibited from effecting the
sale, exchange, transfer, pledge, hypothecation, gift or other disposition of
such shares of Common Stock until the earlier of:

 

  (1) attainment of compliance with applicable stock ownership guidelines;

 

  (2) the Participant’s death, retirement, or permanent disability (as
determined by the Committee); or

 

  (3) the occurrence of the Participant’s Employment Termination Date, for any
reason other than Just Cause.

 

  (d) These restrictions shall apply to any new, additional or different
securities the Participant may become entitled to receive with respect to such
shares by virtue of a stock split or stock dividend or any other change in the
corporate or capital structure of Sunoco.

 

  (e) Until such time as the restrictions hereunder lapse, the shares will be
held in “book-entry form” and appropriate notation of these restrictions will be
maintained in the records of Sunoco’s transfer agent and registrar. Any share
certificate representing such shares will bear a conspicuous legend evidencing
these restrictions, and the Company may require the Participant to deposit the
share certificate with Sunoco or its agent, endorsed in blank or accompanied by
a duly executed irrevocable stock power or other instrument of transfer.

ARTICLE II

GENERAL PROVISIONS

 

2.1 Effect of Plan; Construction. The entire text of the Plan is expressly
incorporated herein by this reference and so forms a part of this Agreement. In
the event of any inconsistency or discrepancy between the provisions of the PSU
award covered by this Agreement and the terms and conditions of the Plan under
which such PSUs are granted, the provisions in the Plan shall govern and
prevail. The PSUs, the related Dividend Equivalents and this Agreement are each
subject in all respects to, and Sunoco and the Participant each hereby agree to
be bound by, all of the terms and conditions of the Plan, as the same may have
been amended from time to time in accordance with its terms; provided, however,
that no such amendment shall deprive the Participant, without such Participant’s
consent, of any rights earned or otherwise due to the Participant hereunder.

 

2.2 Tax Withholding. All distributions under this Agreement are subject to
withholding of all applicable taxes.

 

  (a) Payment in Cash. Cash payments in respect of any earned PSUs, and/or the
related Dividend Equivalents, shall be made net of any applicable federal,
state, or local withholding taxes.

 

  (b) Payment in Stock. Immediately prior to the payment of any shares of Common
Stock to the Participant in respect of earned PSUs, the Participant shall remit
an amount sufficient to satisfy any Federal, state and/or local withholding tax
due on the receipt of such Common Stock. At the election of the Participant, and
subject to such rules as may be established by the Committee, such withholding
obligations may be satisfied through the surrender of shares of Common Stock
(otherwise payable to the Participant in respect of such earned PSUs) having a
value, as of the date of such earned PSUs first became payable, sufficient to
satisfy the applicable tax obligation.

 

2.3 Administration. Pursuant to the Plan, the Committee is vested with
conclusive authority to interpret and construe the Plan, to adopt rules and
regulations for carrying out the Plan, and to make determinations with respect
to all matters relating to this Agreement, the Plan and awards made pursuant
thereto. The authority to manage and control the operation and administration of
this Agreement shall be likewise vested in the Committee, and the Committee
shall have all powers with respect to this Agreement as it has with respect to
the Plan. Any interpretation of this Agreement by the Committee, and any
decision made by the Committee with respect to this Agreement, shall be final
and binding.

shall not be amended or modified except by an instrument in writing executed by
both parties to this Agreement, without the consent of any other person, as of
the effective date of such amendment.

Articles herein are for reference purposes only and will have no legal force or

or any of its terms and conditions.

 

2.6 Governing Law. The validity, construction, interpretation and effect of this
instrument shall be governed exclusively by and determined in accordance with
