Certain provisions applicable to this Agreement are set forth on Appendix A.

1. Grant of Performance Units. The Compensation Committee of the Board of Directors of the Company (the “Committee”) hereby grants, pursuant to Section 6.4 of the Plan, to Participant the number ofPerformance Units under the Plan communicated to the Participant by the Participant’s manager, which represents the target number of Performance Units subject to this Agreement, which grant is subject to the terms and conditions of this Agreement and the Plan. A “Performance Unit” is an unfunded, unsecured contractual right (commonly referred to as a “phantom unit”) which, upon vesting, entitles Participant to receive a Unit of NuStar Energy L.P. No DERs are granted in connection with this Award of Performance Units.

2. Performance Period. Except as provided below with respect to a Change of Control, the performance period for any Performance Units eligible to vest on any given Normal Vesting Date (as defined below) shall be the calendar year ending on the December 31 immediately preceding such Normal Vesting Date (each, a “Performance Period” and specifically, with respect to each of the 2017, 2018 and 2019 calendar years, the “Year 1 Performance Period,” the “Year 2 Performance Period,” and the “Year 3 Performance Period,” respectively).

3. Vesting and Settlement.

A. Vesting. Except as otherwise provided in this Agreement, the Performance Units granted hereunder shall vest, subject to Section 4, over a period of three years in equal, one-third increments (provided, however, that if such increments would otherwise result in a fractional Performance Unit with respect to the applicable Annual Tranche, such fractional Performance Unit shall be rounded to the nearest whole number) (each increment, an “Annual Tranche” and specifically, with respect to the applicable Performance Period for each of the 2017, 2018 and 2019 calendar years, the “Year 1 Annual Tranche,” the “Year 2 Annual Tranche,” and the “Year 3 Annual Tranche,” respectively). Except as otherwise provided in this Agreement, the applicable portion, if any, of the Year 1 Annual Tranche, the Year 2 Annual Tranche and the Year 3 Annual Tranche shall vest on the respective dates that the Committee certifies the attainment of the Performance Goals applicable to this Award (“Performance Measures”) for the applicable Performance Period in accordance with Section 4 following completion of

the applicable Performance Period (each of these three vesting dates is referred to as a “Normal Vesting Date”). In no event shall the Normal Vesting Date for a Performance Period be later than March 15th of the calendar year following the calendar year in which the applicable Performance Period ends. In no event shall any Performance Units granted hereunder that form part of a particular Annual Tranche be eligible to vest following the Normal Vesting Date applicable to such Annual Tranche. Any Performance Units granted hereunder that form part of a particular Annual Tranche and that do not vest as of the Normal Vesting Date applicable to such Annual Tranche shall be automatically and immediately forfeited for no consideration. In no event shall a number of Performance Units greater than 200% of the number set forth in Section 1 vest under any circumstances.

B. Settlement. Except as provided otherwise in Section 6, any Performance Units that vest pursuant to this Agreement shall be settled as soon as reasonably practical after the applicable Normal Vesting Date and in all events no later than March 15 of the calendar year following the end of the applicable Performance Period. This Agreement and the Award evidenced hereby are intended to comply with or otherwise be exempt from, and shall be administered consistently in all respects with, Section 409A of the Code and the regulations promulgated thereunder. If necessary in order to attempt to ensure such compliance, this Agreement may be reformed, to the extent possible, unilaterally by the Company consistent with guidance issued by the Internal Revenue Service. Participant agrees that the Units to which Participant will be entitled in connection with the vesting, if any, of each Performance Unit may be in uncertificated form and recorded with the Company’s or its Affiliates’ service provider.

4. Performance Measures.

A. Performance Unit Vesting for the Year 1 Performance Period. The Year 1 Annual Tranche shall vest based on the distribution coverage ratio achievedbyNuStar Energy L.P. (“DCR”) during the Year 1 Performance Period as follows:

Level	DCR	Percentage of Year 1 Annual Tranche Vesting (Year 1 Performance Multiplier)
Below Threshold	Below 1.00 : 1	0%
Threshold	1.00 : 1	90%
Target	1.01 : 1	100%
Exceeds Target	1.05 : 1	150%
Maximum	1.10 : 1	200%

If actual performance is between performance levels, the Year 1 Performance Multiplier will be interpolated on a straight line basis for achievement between performance levels. Notwithstanding the foregoing, the Committee has full discretion to vest between 0%

and 200% of the Year 1 Annual Tranche, regardless of the DCR for the Year 1 Performance Period.

B. Performance Unit Vesting for Year 2 and Year 3. The Committee will designate the Performance Measures that will apply for the Year 2 Performance Period and the Year 3 Performance Period (the “Year 2 Performance Measures” and the “Year 3Performance Measures,” respectively) in the first quarter of the applicable calendar year based on the Company’s approved budget for such applicable year. Within the Committee’s discretion, the Year 2 Performance Measures and the Year 3 Performance Measures may result in the vesting of greater than 100% (up to 200%) of the Year 2 Annual Tranche and the Year 3 Annual Tranche, respectively. The Year 2 Performance Measures and the Year 3 Performance Measures shall be applied to the Year 2 Annual Tranche and the Year 3 Annual Tranche, respectively, to determine the Performance Units that vest with respect to the applicable Performance Period. Notwithstanding the foregoing, the Committee has full discretion to vest between 0% and 200% of the applicable Annual Tranche, regardless of the level of Performance Measures achieved by NuStar Energy L.P. for that year.

B. Death, Disability and Termination by the Company Other Than for Cause. Except for a Change of Control, if Participant experiences a Disability (as defined below) or if Participant’s employment with the Company or an Affiliate is terminated by the Company or an Affiliate other than for Cause (at a time when Participant is otherwise willing and able to continue providing services) or as a result of Participant’s death (each, a “Triggering Event”), and the then-current Performance Period will be completed in fewer than 30 days after such Triggering Event, the Annual Tranche applicable to the then-current Performance Period shall vest and be settled in accordance with Sections 3 and 4 as if Participant had remained employed through the last day of the Performance Period. Any Performance Units that fail to vest for the then-current Performance Period after the application of the previous sentence, including any Performance Units for any Performance Periods that would otherwise have commenced following the Triggering Date, shall be automatically and immediately forfeited for no consideration. Any Performance Units that vest pursuant to this Section 5B shall be settled as soon as administratively practicable after the applicable Normal Vesting Date and in all events no later than March 15 of the calendar year following the end of the calendar year in
