HOLLY CORPORATION REPORTS THIRD QUARTER OF FISCAL 2003 RESULTS

         Dallas, Texas, June 12, 2003 -- Holly Corporation (AMEX-HOC), today
reported results for the Company's third quarter and nine months ended April 30,
2003.

         Net income for the three months ended April 30, 2003 was $26.7 million
($1.67 per diluted share) compared to net income of $6.2 million ($.39 per
diluted share) for the three months ended April 30, 2002. For the nine months
ended April 30, 2003, net income was $30.4 million ($1.90 per diluted share)
compared to $25.9 million ($1.62 per diluted share) for the nine months ended
April 30, 2002. During the fiscal 2003 third quarter, the Company's income
benefited from a $16.4 million gain ($10.2 million after tax) from the sale of
pipeline assets to Plains Marketing, L.P., the $15.2 million ($9.4 million after
tax) received from Kinder Morgan Energy Partners, L.P. as payment for
reparations ordered by the Federal Energy Regulatory Commission, and strong
refining margins that improved substantially from the first six months of the
current fiscal year and compared very favorably to margins for the three months
ended April 30, 2002. Excluding the pipeline sale and reparations payment, net
income for the three and nine months ended April 30, 2003 would have been $7.1
million ($.44 per diluted share) and $10.7 million ($.67 per diluted share),
respectively.

         For the Company's third quarter ended April 30, 2003, refining margins
of $8.86 per barrel were significantly higher than the refinery margins of $6.40
per barrel for the quarter ended April 30, 2002. Refining margins rose to high
levels during much of the current year's third quarter as refined product prices
rose at a greater rate than crude oil costs, but the high margins fell off late
in the quarter as refined product prices declined at a greater rate than crude
oil costs. For the nine months ended April 30, 2003, refining margins of $6.37
per barrel were less than the refinery margins of $7.13 per barrel for the nine
months ended April 30, 2002. The relative strength of the prior year's
nine-month margins was principally the result of strong margins in the fiscal
2002 first quarter, when the Company, along with the refining industry as a
whole, was still experiencing very favorable refining margins, which fell off
significantly after the prior year's first fiscal quarter.



                                       1


         As mentioned above, the current year's third quarter had two
significant nonrecurring events that contributed substantially to earnings. As
previously announced, the Company in March 2003 sold its Iatan crude oil
gathering system located in west Texas to Plains Marketing, L.P., resulting in a
gain of $16.4 million. Additionally, in April 2003 the Company received from
Kinder Morgan Energy Partners, L.P. a payment of $15.2 million for reparations
ordered by the Federal Energy Regulatory Commission relating to tariffs on
common carrier pipeline shipments of refined products from 1993 to July 2000.

         The Company's revenues and cost of products sold were higher in the
third quarter and nine months of fiscal 2003, as compared to the comparable
periods in fiscal 2002, due principally to higher refined product sales prices
and higher costs of purchased crude oil. Additionally, refined product sales
volumes increased for the three-month and nine-month periods by 5% and 10%,
respectively, as compared to the same periods of fiscal 2002. Negatively
impacting earnings for the both the three and nine months ended April 30, 2003,
as compared to the prior year periods, were increases in operating expenses, due
to higher utility costs, higher environmental costs, and increased compensation
expense, and losses at our asphalt joint venture, compared to substantial income
of the asphalt joint venture for the fiscal 2002 three- and nine-month periods.

         "The Company experienced a very good third quarter as refining margins
rebounded nicely and the pipeline sale and FERC-ordered reparations payment
contributed to earnings. Excluding the two non-recurring items, we generated
over $20 million of earnings before interest, taxes and depreciation for the
fiscal 2003 third quarter," said Matthew P. Clifton, President of Holly. "As
recently announced, the acquisition of the Woods Cross refinery near Salt Lake
City from ConocoPhillips closed effective June 1, 2003. We are very excited
about adding the Woods Cross operations to the Company, which acquisition
increased our total current refining capacity by approximately 35%.
Additionally, the Company is continuing to work diligently in the construction
of a gas oil hydrotreating unit at its Artesia, New Mexico refinery facility
which is designed to satisfy future EPA mandated gasoline specifications and to
improve the refinery's yields of higher value products. The expansion of our New
Mexico facility that will result in a further increase of approximately 15% in
Holly's overall refining capacity is expected to be completed along with the
hydrotreating unit by the end of calendar 2003. In addition to our on-going
steps to move forward and strengthen the Company, we are continuing to plan for
the proposed merger with Frontier Oil Corporation, which is expected to be
submitted in the next few weeks to the stockholders of both companies for their
approval."

         Holly, headquartered in Dallas, Texas, operates a 60,000 bpd refinery
located in Artesia, New Mexico that is being expanded to 75,000 bpd, a 25,000
bpd refinery in Woods Cross, Utah, and a 7,500 bpd refinery in Great Falls,
Montana. Holly also has approximately 2,000 miles of crude oil and refined
product

pipelines in the west Texas and New Mexico region, Permian Basin crude gathering

2)      The Refining segment includes the Company's principal refinery in
        Artesia, New Mexico, which is operated in conjunction with refining
        facilities in Lovington, New Mexico (collectively, the Navajo Refinery)
        and the Company's refinery near Great Falls, Montana. Included in the
        Refining segment are costs relating to pipelines and terminals that
        operate in conjunction with the Refining segment as part of the supply
        and distribution networks of the refineries. The Pipeline Transportation
        segment includes approximately 1,000 miles (approximately 600 miles
        after the sale of pipelines to Plains Marketing, L.P.) of the Company's
        pipeline assets in Texas and New Mexico. Revenues of the Pipeline
        Transportation segment are earned through transactions with unaffiliated
        parties for pipeline transportation, rental and terminalling operations.

3)      Earnings Before Interest, Taxes, Depreciation and Amortization - EBITDA
        is calculated as net income plus (i) interest expense net of interest
        income, (ii) income tax provision, and (iii) depreciation, depletion,
        and amortization. EBITDA is presented, not as an alternative measure of
