NUSTAR ENERGY L.P.

UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

Introduction

As used in this report, references to “we,” “us” or “our” collectively refer to NuStar Energy L.P.

The following unaudited pro forma combined financial statements give effect to our acquisition on March 20, 2008 of CITGO Asphalt Refining Company’s asphalt operations and assets (the CARCO Assets) for a total of $808.3 million. In addition, we assumed certain environmental and employee-related liabilities. The CARCO Assets include asphalt refineries in Paulsboro, New Jersey and Savannah, Georgia and three asphalt terminals. We funded the acquisition with proceeds from our common unit offerings in November 2007 and April 2008, related contributions from our general partner to maintain its 2% interest, proceeds from our issuance of $350.0 million of senior notes and borrowings under our revolving credit agreement.

The unaudited pro forma combined balance sheet as of December 31, 2007 is presented as if the acquisition of the CARCO Assets had occurred on that date. The unaudited pro forma combined statement of income assumes that the acquisition occurred on January 1, 2007. The estimates of fair value of the assets acquired and liabilities assumed are based on preliminary assumptions, pending the completion of an independent appraisal and other evaluations.

The unaudited pro forma combined financial statements should be read in conjunction with (i) the audited historical consolidated financial statements of NuStar Energy L.P. included in its Annual Report on Form 10-K for the year ended December 31, 2007; and (ii) the audited historical consolidated financial statements of CITGO Asphalt Refining Company for the year ended December 31, 2007 included herein. The unaudited pro forma combined financial statements are not necessarily indicative of the financial position that would have been obtained or the financial results that would have occurred if the acquisition of the CARCO Assets had been consummated on the dates indicated, nor are they necessarily indicative of the financial position or results of operations in the future. The pro forma adjustments, as described in the notes to unaudited pro forma combined financial statements, are based upon available information and certain assumptions that our management believes are reasonable.

The unaudited pro forma combined financial statements do not give effect to any anticipated cost savings or other financial benefits expected to result from the acquisition of the CARCO Assets.

NUSTAR ENERGY L.P.

NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

Pro Forma Adjustments:

 

(a) To reflect the sale of $350.0 million of 7.65% senior notes due April 15, 2018, net of discount of $0.7 million, and the borrowings on our variable rate revolving credit agreement of $69.3 million. Debt issuance costs of $2.4 million and $0.3 million related to the $350.0 million senior notes and revolving credit agreement, respectively, were capitalized and will be amortized over the life of each debt instrument.

 

(b) To record the sale of 5,050,800 common units of NuStar Energy L.P. at a price of $48.75 per unit for net proceeds of $236.2 million.

 

(c) To record a capital contribution from the general partner of NuStar Energy L.P. of $5.0 million to maintain its 2% ownership interest in NuStar Energy L.P.

 

(d) To reflect the proceeds of the November 2007 equity offering and the related general partner contribution totaling $146.0 million, which were originally used to partially repay the balance outstanding on our revolving credit agreement.

 

(e) For purposes of this pro forma analysis, the estimated purchase price has been allocated based on a preliminary assessment of the fair value of the assets acquired and liabilities assumed, pending the completion of an independent appraisal and other evaluations. Management does not expect to allocate a significant amount of the purchase price to goodwill or identifiable intangible assets, as there is little intellectual property involved in the operation of the acquired business. However, the results of the pending appraisal may reflect a value for certain customer contracts or other identifiable intangible assets, the quantification of which cannot be determined at this time. The purchase price and preliminary purchase price allocation results in the following pro forma adjustments (in thousands):

 

Inventory

   $ 326,715

Other current assets

     1,439

Property, plant and equipment

     451,863

Other noncurrent assets

     28,316
      

Purchase price

     808,333

Less liabilities assumed

     5,178
      

Preliminary purchase price allocation

   $ 803,155
      

November 2007 equity offering

   $  143,000

Contributions from our general partner to maintain its 2% interest

     3,035

April 2008 equity offering

     236,227

Contributions from our general partner to maintain its 2% interest

     5,025

Senior note offering, net of issuance costs

     346,882

Borrowings on revolving credit agreement, net of issuance costs

     68,986
      

Total sources

   $ 803,155
      

 

(f) To adjust cost of product sales from the LIFO method to the weighted-average cost method, which is the method we use.

 

(g) To adjust depreciation expense for the preliminary purchase price allocation to property, plant and equipment for the year ended December 31, 2007 based on an estimated life of 25 years and no salvage value.

 

(h) To reflect interest expense of $31.1 million for the year ended December 31, 2007 attributable to (i) the sale of $350.0 million of 7.65% senior notes, (ii) borrowings on our variable rate revolving credit agreement, (iii) the amortization of debt issuance costs, and (iv) amortization of debt discount. For pro forma presentation purposes, the debt discount and the debt issuance costs associated with each debt instrument have been amortized from January 1, 2007 using the effective interest method. A 1/8% change in the interest rate associated with the borrowings under our revolving credit agreement would have a $0.1 million effect on interest expense for the year ended December 31, 2007.

 

(i) The pro forma adjustments to the statements of income have not been tax-effected as the effect on income tax is not material.
