   Expected by Western to be Immediately Accretive to Western's Cash Flow
                         and Earnings Per Share

EL PASO, Texas and SCOTTSDALE, Arizona - August 28, 2006 - Western Refining,
Inc. (NYSE:WNR) and Giant Industries, Inc. (NYSE:GI) today announced that
the Boards of Directors of both companies have unanimously approved a
definitive merger agreement under which Western will acquire all of the
outstanding shares of Giant for $83.00 per share in cash. The transaction
is valued at approximately $1.5 billion, including approximately $275
million of Giant's outstanding debt.

After completing the transaction, Western will be the fourth largest
publicly-traded independent refiner and marketer in the United States with
a total crude oil throughput capacity of approximately 216,000 barrels per
day (bpd). In addition to Western's 117,000 bpd refinery in El Paso, Texas,
Western will gain an East Coast presence with a 62,000 bpd refinery in
Yorktown, Virginia and will gain two refineries in the Four Corners region
of Northern New Mexico with a current combined capacity of 37,000 bpd.
Western's primary operating areas will encompass the Mid-Atlantic region,
far West Texas, Phoenix and Tucson, Arizona, Northern Mexico, Albuquerque,
New Mexico and the Four Corners region of Utah, Colorado, Arizona and New
Mexico. In addition to the four refineries, Western's asset portfolio will
include refined products terminals in Flagstaff, Arizona and Albuquerque,
as well as asphalt terminals in Phoenix, Tucson, Albuquerque and El Paso.
Western's asset base will also include 159 retail service stations and
convenience stores in Arizona, Colorado and New Mexico, a fleet of
approximately 100 crude oil and finished product truck transports, and two
wholesale petroleum products distributors - Phoenix Fuel Co., Inc. in
Arizona and Dial Oil Co. in New Mexico.

"This transaction is a win for our shareholders, employees, customers and
the communities we serve," said Western's President and Chief Executive
Officer, Paul Foster. "With Giant, we will significantly increase our
refining capacity in fast growing, high demand areas and gain an immediate
footprint in new, complementary businesses. With this enhanced growth
platform and Western's continued financial strength, we will be better able
to capitalize on the strong fundamentals in our industry and drive
shareholder value.

"We look forward to Giant's employees joining the Western team following
closing. I'm confident that the substantial employee talent and operating
expertise from both companies will enable us to achieve significant growth
from our asset portfolio and realize the substantial upside potential we
see with this combination. As we move forward and grow together, we intend
to maintain our record of safety and environmental stewardship that has
made us an industry leader," continued Mr. Foster.

Fred Holliger, Giant's Chairman and Chief Executive Officer, said, "The
transaction provides Giant shareholders with a meaningful return on their
investment and recognizes the value of our strategy and assets for our
shareholders. The transaction also offers our employees the opportunity to
be part of a larger organization with greater economies of scale and
resources needed for sustained success in our industry. Western is a
company that we know well, and we believe that our employees will benefit
from the cultural fit. I thank each of our employees for their many
contributions that have helped build Giant and achieve the successes that
enabled our shareholders to realize the significant value this transaction
will deliver. Giant's Board of Directors has unanimously approved the
transaction and will recommend that shareholders vote in favor of it. We
are committed to completing the transaction as expeditiously as possible
and to ensuring a seamless transition."

Benefits of the Transaction to Western

- -  Enhanced Refining Platform in Key Growth Areas: By expanding its
   refining operations from one to four facilities, Western will
   significantly diversify its operations in fast growing, high demand
   areas.

   In addition, Western will double its lower-cost sour and heavy crude
   processing capacity from approximately 12% currently to almost 25%;
   Western's sour and heavy crude processing capacity will reach 46%
   following the completion of its previously announced expansion program
   at its El Paso facility. The Yorktown, Virginia refinery also has the
   flexibility to incorporate future growth initiatives given its ability
   to process cost-advantaged feedstocks.

- -  Immediate Footprint in Complementary Businesses: Currently Western
   generates most of its revenues from its refining operations in El Paso.
   Following the close of the transaction, Western will generate revenue
   from four different refineries as well as a diverse mix of complementary
   retail and wholesale businesses.

- -  Operational Efficiencies and Cost Savings: The transaction is expected
   by Western to generate refinery efficiencies and cost savings of
   approximately $20 million annually in 2008. Western expects to derive
   approximately half of these synergies from improved efficiencies at its
   refineries and the remainder from savings achieved through the
   consolidation of overlapping functions. Significant workforce reductions
   are not expected.

- -  Accelerated Cash Flow and Earnings Growth: Western expects the
   transaction to be immediately and significantly accretive to its cash
   flow and earnings per share, excluding one-time transaction costs.

- -  Financial Strength and Flexibility: The transaction will be funded
   through a combination of approximately $250 million in cash on hand and
   a $2.0 billion commitment from Bank of America, consisting of up to a
   $1.5 billion senior secured term loan and a $500 million senior secured
   revolving credit facility. Based on June 30, 2006 figures, initial pro
   forma debt to trailing twelve months adjusted EBITDA will be 2.4x with
   an adjusted EBITDA to interest expense of 5.2x. Following the
   transaction, Western believes its strong cash flow from operations will
   allow it to reduce its net debt and fully fund its capital program. The
   limited amortization payments and prepayable nature of the term loan
   provide Western significant financial flexibility.

Western Dividend Policy

It is currently anticipated that Western's Board of Directors will continue
its regular quarterly cash dividend of $0.04 per share on Western's common
stock. However, declarations of dividends are determined by the Board of
Directors each quarter after its review of Western's financial performance.

Western Management and Headquarters

Following the close of the transaction, Paul Foster will remain President
and Chief Executive Officer of Western, and Fred Holliger will serve as a
special advisor to Western's Board of Directors. The combined company will
be headquartered in El Paso and will maintain offices in Scottsdale.

Path to Closing

The transaction is subject to approval by Giant shareholders and the
satisfaction of customary closing conditions and regulatory approvals,
including expiration or termination of the applicable waiting period under
the Hart-Scott-Rodino Antitrust Improvements Act. The transaction is
expected to close in the fourth quarter of 2006 and is not subject to any
financing conditions.

Western has a track record of successfully executing on strategic
transactions. Given the complementary nature of Western and Giant's
businesses, Western expects to realize the benefits of this transaction
quickly and efficiently.

In connection with the transaction, Giant anticipates that it will commence
a tender offer and consent solicitation relating to Giant's 8% Senior
Subordinated Notes due 2014 and 11% Senior Subordinated Notes due 2012.
Details with respect to this tender offer and consent solicitation will be
set forth in tender offer documents, which will be furnished to the holders
of the notes at the appropriate time.

Adjusted EBITDA Reconciliation

Adjusted EBITDA represents earnings before interest expense, income tax
expense, amortization of loan fees, write-off of unamortized loan fees,
depreciation, amortization and maintenance turnaround expense. However,
Adjusted EBITDA is not a recognized measurement under GAAP. Our management
believes that the presentation of Adjusted EBITDA is useful to investors
because it is frequently used by securities analysts, investors and other
interested parties in the evaluation of companies in our industry. In
addition, our management believes that Adjusted EBITDA is useful in
evaluating our operating performance compared to that of other companies in
our industry because the calculation of Adjusted EBITDA generally
eliminates the effects of financings, income taxes and the accounting
effects of significant turnaround activities (which many of our competitors
capitalize and thereby exclude from their measures of EBITDA) and
acquisitions, items that may vary for different companies for reasons
unrelated to overall operating performance.

Adjusted EBITDA has limitations as an analytical tool, and you should not
consider it in isolation, or as a substitute for analysis of our results as
reported under GAAP. Some of these limitations are:

- -  Adjusted EBITDA does not reflect our cash expenditures or future
   requirements for significant turnaround activities, capital expenditures
   or contractual commitments;
- -  Adjusted EBITDA does not reflect the interest expense or the cash
   requirements necessary to service interest or principal payments on our
   debt;
- -  Adjusted EBITDA does not reflect changes in, or cash requirements for,
   our working capital needs; and
- -  our calculation of Adjusted EBITDA may differ from the Adjusted EBITDA
   calculations of other companies in our industry, thereby limiting its
   usefulness as a comparative measure.

Because of these limitations, Adjusted EBITDA should not be considered a
measure of discretionary cash available to us to invest in the growth of
our business. We compensate for these limitations by relying primarily on
our GAAP results and using Adjusted EBITDA only supplementally.
