2010 results expected to be $22 to $26 million higher

than 2009

NuStar

has generated strong earnings growth in its

storage segment mainly due to:

$400 million construction program started in 2006

and completed in 2009

Higher rates on storage contract renewals

Refined product demand growth outside the U.S. should

continue to benefit companies like NuStar

funds available for highway projects,

Up from the $5.6 billion spent in

2009

Weak private sector demand for asphalt expected to impact margins in the

second half of 2010

Improved results in our bunker fuel sales, fuel oil sales and refined products

trading should contribute to improved results.
