                                PART III
                                NARRATIVE

     State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q,
10-D, N-SAR, N-CSR, or the transition report or portion thereof, could
not be filed within the prescribed time period.

     Giant Industries, Inc. (the "Company") was unable to file its Form
10-Q for the quarter ended September 30, 2006 by the November 9, 2006
filing due date, and represents that the reasons for its inability to
timely file the Form 10-Q could not be rectified without unreasonable
effort or expense. On November 13, 2006, the Company filed a Form 8-K
with the Securities and Exchange Commission that includes a copy of a
Press Release, which announced an amendment (the "Amendment") to the
Agreement and Plan of Merger, dated as of August 26, 2006 (the "Merger
Agreement"), among Western Refining, Inc. ("Western"), New Acquisition
Corporation, and the Company, the actual Amendment, and a Press Release
announcing the Company's earnings for the quarter ended September 30,
2006.

     Pursuant to the Merger Agreement, Western has agreed to acquire
the outstanding equity of the Company in a merger transaction.  The
Company and Western have been dealing with matters relating to the
Amendment.  While the Amendment has no effect whatsoever on the Company's
reported financial statements, it does impact the narrative included in the
Form 10-Q, including Item 2, the Management's Discussion and Analysis of
Financial Condition and Results of Operations.  Accordingly, the Company
needed to conclude the Amendment before it could complete the Form 10-Q.

     As described in the earnings Press Release noted above, for the
quarter ended September 30, 2006, the Company had net earnings of $44.0
million, or $3.00 per diluted share. Net earnings were $46.6 million, or
$3.38 per diluted share in the third quarter of 2005. The Company had net
earnings of $80.9 million, or $5.51 per diluted share, for the first nine
months of 2006 compared to net earnings of $77.3 million, or $5.80 per
diluted shares in 2005.

     The Company will file the Form 10-Q not later than November 14,
2006.
