For Immediate Release

HOLLY CORPORATION REPORTS FOURTH QUARTER AND RECORD FULL YEAR 2007 RESULTS

     Dallas, Texas, February 19, 2008 — Holly Corporation (NYSE-HOC) (“Holly” or the “Company”) today reported quarterly net income of $49.8 million ($0.92 per basic and $0.90 per diluted share) for the three months ended December 31, 2007, compared to net income of $47.7 million ($0.86 per basic and $0.84 per diluted share) for the three months ended December 31, 2006. Net income was a record $334.1 million ($6.09 per basic and $5.98 per diluted share) for the year ended December 31, 2007, compared to net income of $266.6 million ($4.68 per basic and $4.58 per diluted share) for the year ended December 31, 2006.

     Net income increased by 5% or $2.2 million for the three months ended December 31, 2007, as compared to the three months ended December 31, 2006, principally due to the positive effects of increased sales of sulfur credits, higher sales of produced refined products, lower general and administrative expenses, increased earnings from our equity interest in Holly Energy Partners, L.P., an increase in interest income and a decrease in income taxes. All of these factors were partially offset by lower refinery gross margins and higher operating expenses. Sulfur credit sales totaled $15.1 million for the three months ended December 31, 2007, an increase of $11.1 million over the three months ended December 31, 2006. For the three months ended December 31, 2007, volumes of produced refined products sold increased by 6,910 barrels per day (“BPD”) or 6% as compared to the three months ended December 31, 2006. Overall refinery gross margins were $9.83 per produced barrel for the three months ended December 31, 2007, as compared to $12.08 for the three months ended December 31, 2006. Overall sales and other revenues for the three months ended December 31, 2007 increased 54% or $502.1 million, as compared to the three months ended December 31, 2006. The increase is principally due to higher sales prices in the fourth quarter of 2007 as compared to 2006.

     Net income from continuing operations increased by 35% or $87.2 million for the year ended December 31, 2007, as compared to the year ended December 31, 2006, principally due to an overall increase in refined product margins during the first half of the current year combined with an increase in volumes of produced refined products sold, partially offset by an increase in total operating costs and expenses and an overall decrease in refined product margins during the second half of the year. Overall refinery gross margins were $16.74 per produced barrel for the year ended December 31, 2007, as compared to $15.78 for the year ended December 31, 2006. Overall sales and other revenues for the year ended December 31, 2007 increased 19% or $768.5 million, as compared to the year ended December 31, 2006.

     The increase in volume of produced refined products sold for the year ended December 31, 2007, as compared to the same period in 2006, is attributable to increased production levels during the current year. Our production levels were lower for the year ended December 31, 2006 due to planned downtime attributable to our ultra low sulfur diesel (“ULSD”) fuel project at our Navajo Refinery during the second quarter of 2006. Also contributing to our production increase for the year ended December 31, 2007 as compared to 2006 is an increase in production levels at our Navajo Refinery following an 8,000 barrels per stream day (“BPSD”) refinery expansion in mid-year 2006 combined with an additional 2,000 BPSD expansion in mid-year 2007. For the year ended December 31, 2007, our consolidated refinery production levels increased by 7,540 BPD or 7% as compared to 2006.

     “We are extremely pleased with our 2007 results. 2007 was our fourth consecutive record year, with net income from continuing operations increasing 35% over our previous 2006 record results. Higher gross margins at our Woods Cross Refinery, record overall refinery production levels and lower per barrel operating expenses resulted in significantly improved financial results,” said Matthew Clifton, Chairman of the Board and Chief Executive Officer of Holly. “During the year, we also made substantial progress on both our Woods Cross and Navajo Refinery expansion and crude flexibility capital projects. These projects, expected to be completed at the end of the third quarter of 2008 and during 2009, respectively, remain on budget. Furthermore, our Salt Lake City to Las Vegas joint venture pipeline, expected to be operational in mid 2009, also remains on budget. Finally, we continued to return cash to our shareholders, spending $211.1 million to purchase approximately 4.0 million shares during 2007.

-2-

For 2007, we generated earnings before interest, taxes and depreciation (“EBITDA”) from continuing operations of $528.9 million as compared to $414.5 million of EBITDA from continuing operations for 2006.”

     Commenting on the fourth quarter, Clifton said “our fourth quarter 2007 results reflect the positive effects of increased sulfur credit sales and refinery gross margins at Woods Cross as compared to the same period in 2006. These factors were partially offset by lower refinery gross margins at our Navajo Refinery. Gross margins at the Navajo Refinery were negatively impacted during the fourth quarter of 2007, by lower West Coast gasoline prices which indirectly affect gasoline prices in the Phoenix market, one of Navajo’s primary markets.”

Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles

Reconciliations of earnings before interest, taxes, depreciation and amortization (“EBITDA”) to amounts reported under generally accepted accounting principles in financial statements.

Earnings before interest, taxes, depreciation and amortization, which we refer to as 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 not a calculation based upon accounting principles generally accepted in the United States; however, the amounts included in the EBITDA calculation are derived from amounts included in our consolidated financial statements. EBITDA should not be considered as an alternative to net income or operating income as an indication of our operating performance or as an alternative to operating cash flow as a measure of liquidity. EBITDA is not necessarily comparable to similarly titled measures of other companies. EBITDA is presented here because it is a widely used financial indicator used by investors and analysts to measure performance. EBITDA is also used by our management for internal analysis and as a basis for financial covenants. We are reporting EBITDA from continuing operations.

Set forth below is our calculation of EBITDA from continuing operations.

Reconciliations of refinery operating information (non-GAAP performance measures) to amounts reported under generally accepted accounting principles in financial statements.

Refinery gross margin and net operating margin are non-GAAP performance measures that are used by our management and others to compare our refining performance to that of other companies in our industry. We believe these margin measures are helpful to investors in evaluating our refining performance on a relative and absolute basis.

We calculate refinery gross margin and net operating margin using net sales, cost of products and operating expenses, in each case averaged per produced barrel sold. These two margins do not include the effect of depreciation, depletion and amortization. Each of these component performance measures can be reconciled directly to our Consolidated Statements of Income.

Other companies in our industry may not calculate these performance measures in the same manner.

Refinery Gross Margin

Refinery gross margin per barrel is the difference between average net sales price and average cost of products per barrel of produced refined products. Refinery gross margin for each of our refineries and for both of our refineries on a consolidated basis is calculated as shown below.

(1)	We purchase finished products when opportunities arise that provide a profit on the sale of such products, or to meet delivery commitments.
(2)	We purchase crude oil and enter into buy/sell exchanges in excess of the needs to supply our refineries. Certain direct sales of this excess crude oil are made to purchasers or users of crude oil. Under new accounting guidance, these sales and related purchases starting April 1, 2006 are being measured at fair value and accounted for as revenues with the related acquisition costs included as cost of products sold. Prior to April 1, 2006, sales and cost of sales attributable to such excess crude oil direct sales were netted and presented in cost of products sold.
(3)	Other refining segment revenue includes the revenues associated with NK Asphalt Partners and revenue derived from sulfur credit sales.
(4)	The above calculations of refined product sales from produced products sold can also be computed on a consolidated basis. These amounts may not calculate exactly due to rounding of reported numbers.
