Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

On February 26, 2010, the Committee also approved awards of performance units for each of the Company’s named executive officers pursuant to the terms of the Company’s 2000 Amended and Restated Long-Term Incentive Plan (the “LTIP”). The performance units are payable in NuStar Energy L.P.’s common units (the “Common Units”). The performance units vest annually in one-third increments beginning on the first anniversary of their grant date. Upon vesting, the performance units are converted into a number of Common Units based upon NuStar Energy L.P.’s total unitholder return during rolling three-year periods that end on December 31 of each year following the date of grant. At the end of each performance period, NuStar Energy L.P.’s total unitholder return is compared to its peer group and is ranked by quartile. Holders of the performance units then earn 0 percent, 50 percent, 100 percent or 150 percent of that portion of the initial grant that is vesting, depending upon whether NuStar Energy L.P.’s total unitholder return is in the last, third, second or first quartile, respectively; holders earn 200 percent if NuStar Energy L.P. is the highest ranking entity in the peer group.
