                     PRO FORMA COMBINED FINANCIAL STATEMENTS


The unaudited pro forma combined condensed financial statements give effect to
the following transactions, which are anticipated to occur on May 29, 1998,
(collectively, the "Transactions"):

      (i) Tesoro Petroleum Corporation (the "Company" or "Tesoro") closes the
          acquisition (the "Hawaii Acquisition") of all of the outstanding
          capital stock of BHP Petroleum Americas Refining Inc. and BHP South
          Pacific Inc. (together, "BHP Hawaii"), both of which are affiliates of
          The Broken Hill Proprietary Company Limited ("BHP"). The cash 
          purchase price for the Hawaii Acquisition is $275 million, subject to
          adjustment for an amount by which working capital of BHP Hawaii at the
          closing date differs from $100 million. In addition, Tesoro will issue
          an unsecured, non-interest bearing promissory note (the "BHP Note") in
          the amount of $50 million, payable in five equal annual installments
          of $10 million each, beginning on the eleventh anniversary date of the
          closing.

      (ii)In conjunction with closing the Hawaii Acquisition, Tesoro will borrow
          funds to finance the cash consideration for the Hawaii Acquisition and
          refinance substantially all of its existing indebtedness. These
          borrowings will be financed through term loans and a revolving credit
          facility which will be fully underwritten by Lehman Brothers.

The unaudited pro forma combined condensed financial statements have been
prepared from, and should be read in conjunction with, the historical combined
financial statements and notes thereto of BHP Hawaii, which are included as
Exhibits 99.1 and 99.2 to this Form 8-K, and the historical consolidated
financial statements and notes thereto of Tesoro which have been previously
filed. The Hawaii Acquisition will be accounted for using the purchase method of
accounting for Tesoro's acquisition of BHP Hawaii after giving effect to the pro
forma reclassifications and adjustments described in the accompanying notes.

The Unaudited Pro Forma Combined Condensed Balance Sheet gives effect to the
Transactions as if each had occurred on December 31, 1997. The Unaudited Pro
Forma Combined Condensed Statement of Operations for the year ended December 31,
1997 gives effect to the Transactions as if each had occurred on January 1,
1997. BHP Hawaii's results of operations, which are reported on a fiscal year
ending May 31, have been adjusted to a December 31 year end. The estimates of
the fair value of BHP Hawaii's assets and liabilities are based on valuations
that are preliminary. Such valuations will be updated to the closing date of the
Hawaii Acquisition and may change from the amounts shown herein; however, the
Company does not expect such changes to be material.

The unaudited pro forma combined condensed financial statements are intended for
informational purposes and are not necessarily indicative of the future
financial position or future results of the combined companies or of the
financial position or the results of operations that would have actually
occurred had the Hawaii Acquisition been in effect as of the date or for the
period presented. The Unaudited Pro Forma Combined Condensed Statement of
Operations does not reflect any benefits from cost savings or revenue
enhancements that are anticipated to result from the integration of operations
of Tesoro and BHP Hawaii. There can be no assurance that the Hawaii Acquisition,
related financing or any other pending transactions will be consummated.
