NUSTAR EXCESS PENSION PLAN

The NuStar Excess Pension Plan, formerly known as the Valero GP, LLC Excess Pension Plan (hereinafter referred to as the Excess Pension Plan
or the Plan), was established effective as of July 1, 2006 (Effective Date), and is hereby amended and restated effective as of January 1, 2008. The primary purpose of the Plan is to provide benefits to those
employees of NuStar GP, LLC (the Company) and its participating affiliates whose benefits under the NuStar Pension Plan (the Pension Plan) and the Valero Energy Corporation Pension Plan (VEC Pension Plan) are
subject to limitations under the Internal Revenue Code of 1986, as amended (the Code), or are otherwise indirectly constrained by the Code from realizing the maximum benefit available to them under the terms of the Pension Plan and the
VEC Pension Plan.

The Excess Pension Plan is an excess benefit plan as defined under §3(36) of The Employee Retirement
Income Security Act of 1974, as amended (ERISA), for those benefits provided in excess of Section 415 of the Code. Benefits provided as a result of other statutory limitations are limited to a select group of management or other
highly compensated employees. The Excess Pension Plan is not intended to constitute either a qualified plan under the provisions of Section 401 of the Code or a funded plan subject to the Employee Retirement Income Security Act of 1974,
as amended (ERISA).

The Plan was established in connection with a spin-off from the Valero Energy Corporation Excess Pension
Plan (VEC Excess Pension Plan) of the benefit liabilities accrued under the VEC Excess Pension Plan as of the Effective Date with respect to eligible Employees of the Company. In this connection, it is the intent of the Company that this
Plan not constitute a new nonqualified deferred compensation plan, but rather merely the assumption and continuation



1



---

of the VEC Excess Pension Plan, effective as of July 1, 2006, with respect to Eligible Former VEC Employees who accrued a benefit under the VEC Excess
Pension Plan, and to provide benefits described therein to other Employees who became Participants hereunder after such spin-off.

The
Company established the Pension Plan, effective as of July 1, 2006, to provide defined benefit pension benefits to eligible Employees of the Company, with respect to future service. Effective as of July 1, 2006, Employees of the Company
ceased accruing additional benefits under the VEC Pension Plan and the VEC Excess Pension Plan. It is the intent of the Company that this Plan shall assume the liabilities of the VEC Excess Pension Plan with respect to all Eligible Former VEC
Employees, and shall provide a single, nonqualified excess defined benefit for such Employees for their pre-July 1, 2006 benefit accruals under the VEC Excess Pension Plan and their post-July 1, 2006 benefit accruals under this Plan and
that this Plan and the Company shall be solely liable for all benefits due such Eligible Former VEC Employees under this Plan and the VEC Excess Pension Plan.

|                                        |  |                   |  
|--------------------------------------- |  | ----------------- | -
|Participants Years of Credited Service |  | Vested Percentage |

|4.2 | Benefit Formula.
|--- | ----------------

Subject to the provisions of
Sections 4.3, 4.4 and 4.5, the amount of the benefit payable under the Excess Pension Plan shall be equal to Amount 1 less Amount 2 as identified below.

Amount 1 and Amount 2 are as follows:

Amount 1  is equal to 1.6 percent of the Participants Final Average Salary multiplied by his number of years of Credited Service.

Amount 2  is equal to his/her Pension Plan benefit and (for Eligible Former VEC Employees whose benefit liabilities under the VEC Excess Pension Plan were assumed under this Plan in connection with the
spin-off from the VEC Excess Pension Plan to this Plan) his/her VEC Pension Plan benefit.

The Excess Pension Plan benefits payable
hereunder shall be calculated as the Participants Accrued Benefit payable at his/her Normal Retirement Date, determined as if the Participant commenced payment of the Participants Pension Plan benefit and, if applicable, VEC Pension Plan
benefit at the same time as benefits are payable hereunder (even if the Participant had previously commenced his/her Pension Plan benefit and/or VEC Pension Plan benefit, or receives his/her Pension Plan benefit and/or VEC Pension Plan benefit at a
later date), and shall not be recalculated or re-determined at such time as the Participant actually commences payment of his Pension Plan benefit and/or VEC Pension Plan benefit.



7



---

|4.3 | Actuarial Adjustments.
|--- | ----------------------

The benefit payable under
the Excess Pension Plan, as determined in this Section 4, shall be reduced by the Equivalent Actuarial Value increase in the amount of the Pension Plan benefit and/or the VEC Pension Plan benefit as the result of increases in the amount of
maximum benefits payable from qualified plans in accordance with Code Section 415 as and to the extent permitted under Code Section 409A and the regulations and other guidance issued thereunder.



|4.4 | Early Retirement.
|--- | -----------------

If a Participants Excess
Pension Plan benefit is payable prior to his/her Normal Retirement Date, the benefit payable to such Participant shall be subject to adjustment in accordance with the early retirement adjustment factors set forth in the Pension Plan.



|4.5 | Modifications.
|--- | --------------

The Committee shall have the right
to modify the calculation of Amount 1, identified in Section 4.2, as to any Participant as it may desire from time to time; provided, however, that any such modification shall not result in a reduction of Amount 1 below the basic
level provided in Section 4.2, and shall not affect the timing of the payment, or the form, of benefits hereunder.

SECTION 5. PROVISIONS
REGARDING PAYMENT OF BENEFITS.



|5.1 | Form and Time of Payment.
|--- | -------------------------

Except as otherwise
expressly set forth herein, effective as of January 1, 2008, a Participants vested Excess Pension Plan benefit shall be paid to the Participant in a single lump sum payment (i.e., the single sum payment of the monthly life annuity
payable at Normal Retirement Date) as soon as administratively practical following the Participants Separation from Service and, in any event, within 90 days thereafter. Such lump sum amount shall be calculated as of the Participants
Separation from Service by the actuary of the Pension Plan applying actuarial factors used under the Pension Plan. Additionally, in the event that a Participant incurred a Separation from Service prior to January 1, 2008, and: (a) had not
commenced the receipt of benefit payments hereunder, or had commenced the receipt of benefit payments hereunder in a form other than a lump sum payment, such Participants benefits (or remaining benefits as the case may be) hereunder shall be
paid to the Participant in a lump sum payment (i.e., the single sum payment of the monthly life annuity payable at Normal Retirement Date) on, or as soon as reasonably practical after, January 31, 2008, and in any event within ninety
(90) days after such date.



|5.2 | Delay of Certain Payments.
|--- | --------------------------

With respect to any
Participant who is a specified employee, as defined in Code Section 409A and the regulations and rulings issued thereunder, any benefit that becomes payable by reason of such Participants Separation from Service shall not
commence



8



---

prior to the date that is six (6) months following such Participants Separation from Service, or if earlier, the date of the Participants
death (except to the extent that the payment of such benefit is not subject to Code Section 409A, or is subject to an exception to such delay in payment). Such delayed payment shall be made in a single lump sum payment (i.e., the single
sum payment of the monthly life annuity payable at Normal Retirement Date) as soon as reasonably practical following the expiration of such 6-month delay period (and, in any event, within 90 days of such expiration date), and shall be calculated as
of the Participants Separation from Service by the actuary for the Pension Plan applying actuarial factors used under the Pension Plan. The provisions of this Section 5.2 shall not apply: (a) with respect to any benefit that becomes
payable as the result of a reason other than the Participants Separation from Service; or (b) if, at the time of such Participants Separation from Service, no equity of the Company is publicly traded on an established securities
market or otherwise.



|5.3 | Application of Code Section 409A Transaction Relief Provisions.
|--- | ---------------------------------------------------------------

Notwithstanding any other provision of this Plan, between January 1, 2005 and December 31, 2008, the Plan was administered in compliance with applicable transition relief provided by the U.S. Treasury
Department and/or the Internal Revenue Service under applicable guidance, including Notice 2005-1, the Temporary Regulations issued under Code Section 409A, Notice 2007-78, and Notice 2007-86.

SECTION 6. DEATH BENEFIT.



|6.1 | Death Benefit.
|--- | --------------

In the event that a Participant
with a vested, accrued benefit hereunder dies while in the employ of the Company and prior to the payment of his/her benefit, the Surviving Spouse of such Participant, or (if the Participant is not married at the time of his/her death) the
Beneficiary designated by the Participant under the Pension Plan, shall be entitled to receive a death benefit hereunder. The amount of such death benefit shall equal: (a) the preretirement death benefit as calculated under the Pension Plan
without regard to the annual addition limitations of Code section 415 or the Compensation Limit, less (b) the preretirement death benefit payable under the Pension Plan. Such death benefit shall be paid in the form of a single lump sum payment
(i.e., the single lump sum payment of the monthly life annuity payable at Normal Retirement Date) as soon as administratively practical following the Participants death, and, in any event within 90 days thereafter. The payment shall be
calculated by the actuary of the Pension Plan applying actuarial assumptions used under the Pension Plan.

SECTION 7. CHANGE IN CONTROL.



|7.1 | Effect of Change in Control.
|--- | ----------------------------

Upon a Change in
Control, the benefits of all Participants hereunder shall immediately become fully vested. Additionally, the Committee may, within the period beginning thirty (30) days prior to the effective date of the Change in Control, and ending twelve
(12) months after the effective date of the Change in Control, make an irrevocable



9



---

decision to terminate the Plan (and all deferred compensation plans maintained by the Company which must be aggregated with the Plan under Code section 409A)
and distribute all benefits to Participants. In the event of such termination following a Change in Control, the accrued benefits of each Participant (determined as of the date of Plan termination and calculated in the manner provided for in this
Plan) shall be distributed in the form of a lump sum payment within twelve (12) months following the termination of this Plan. In the absence of such Plan termination, a Change in Control shall not alter the time and manner of the payment of
benefits hereunder, and all benefits shall be paid at the time and in the manner as they would otherwise be paid in accordance with the provisions of this Plan.

SECTION 8. ADMINISTRATION.



|8.1 | Committee.
|--- | ----------

The Committee shall administer the
Excess Pension Plan. The Committee shall have the full authority and discretion to interpret, and to determine all questions arising in the administration, interpretation and application of the Excess Pension Plan. Any such determination by the
Committee shall be conclusive and binding on all persons, and shall not be subject to a de novo review. The Committee may delegate any administrative authority or responsibility to a subcommittee or to representatives of the Company.



|8.2 | Claims.
|--- | -------

A Participant, Beneficiary and any other
person who believes he is entitled to any benefit or right provided under the Plan shall have the right to file a written claim with the Committee in the same manner and governed by the same provisions as provided in the claims review provisions of
the Pension Plan.



|8.3 | Binding Arbitration.
|--- | --------------------

Notwithstanding any other
provision of this Plan, any claims relating to or arising out of this Plan which are not resolved under the claims review procedure described in Section 8.2, shall be submitted to, and settled by, mandatory and final arbitration in accordance
with the Companys dispute resolution program.

SECTION 9. AMENDMENT AND TERMINATION.



|9.1 | Amendment and Termination.
|--- | --------------------------

The Company reserves
the right, in its sole discretion, to terminate, suspend or amend the Plan, at any time or from time to time, in whole or in part for whatever reasons it may deem appropriate. However, no such termination, suspension or amendment shall result in the
acceleration of any benefit payment hereunder, nor shall any such termination, suspension or amendment alter, impair or void any Participants (or Beneficiarys) right with respect to a benefit accrued under the Plan as of the date of such
termination, suspension or amendment, except such benefits as are voluntarily forfeited by a Participant or Beneficiary. In the event of termination of the Plan, all benefits accrued hereunder as of the date of such termination shall become fully
vested and non-forfeitable.

|10.1 | No Employment Rights.
|---- | ---------------------

Nothing contained in this
Plan shall be construed as a contract of employment between the Company and an Employee, or as a right of any Employee to be continued in the employment of the Company or as a limitation of the right of the Company to discharge any Employee, with or
without cause.



|10.2 | Assignment.
|---- | -----------

To the maximum extent permitted by
law, no benefit under this Plan shall be assignable or in any manner subject to alienation, sale, transfer, hypothecation, claims of creditors, pledge, attachment or encumbrances of any kind. This provision shall not, however, effect the right of
the Committee, upon its determination that a judgment, decree or order relating to child support, alimony payments or marital property rights of the spouse, former spouse, child or other dependent of a Participant is a Qualified Domestic
Relations Order within the meaning of Code §414(p), to distribute or establish a separate subaccount of all or any portion of a Participants benefits under the Plan to or for the benefit of the beneficiary of the Qualified Domestic
Relations Order in a manner permitted under the Plan.



|10.3 | Withholding Taxes.
|---- | ------------------

The Company shall have the
right to deduct from all payments made under this Plan any federal, state or local taxes required by law to be withheld with respect to such payments. However, any and all taxes payable with respect to any distribution or benefit hereunder shall be
the sole responsibility of the Participant, not of the Company or any Company, whether or not the Company or any Company shall have withheld or collected from the Participant any sums required to be so withheld or collected in respect thereof and
whether or not any sums so withheld or collected shall be sufficient to provide for any such taxes. Without limitation of the foregoing, and except as may otherwise be provided in any separate employment, severance or other agreement between the
Participant and any Company, the individual Participant or Surviving Spouse, as the case may be, shall be solely responsible for payment of any excise, income or other tax imposed (i) upon any payment hereunder which may be deemed to constitute
an excess parachute payment pursuant to Section 4999 of the Code, (ii) based upon a theory that any additional or excise tax is required under Code Section 409A, or (iii) based upon any theory of constructive
receipt of any lump-sum or other amount hereunder.



|10.4 | Rules and Regulations.
|---- | ----------------------

In addition to the
authority and discretion provided to the Committee elsewhere herein, the Committee may, from time to time, adopt rules and regulations to assist in the administration of the Plan.
