Appendix: Benefits from tax legislation Sulfur credits Definitions

Tax Benefits American Jobs Creation Act of 2004: Created tax incentives for small refiners to produce ULSD Provides immediate deduction of 75% of certain capital costs Provides a tax credit based on ULSD production up to 25% of these costs Energy Policy Act of 2005: Provides an election to expense 50% of refinery capacity expansion costs when assets placed in service Expected benefits to Holly: Base tax rate of 39% will be reduced by est. tax credit of approx.$15 million in 2007

Sulfur Credits Benefit Benefits to Holly: Can use as needed in future years. Can monetize if not used internally. In 2006, Holly sold 99,681 credits totaling approximately $16 million Credit Generation: Compliance with Low Sulfur gasoline for small refiners, including Holly, not required until the end 2010. Holly installed a hydrotreater at the Navajo refinery in 2003, thereby lowering the sulfur content of its gasoline below the '"small refiner standard". Holly elected to produce 95 plus % ULSD and increased it's gasoline sulfur baseline by 20%. Since 2004, Holly has generated sulfur credits that have value. At the end of 2005 Holly had approximately160,000 credits ( one credit equal a million ppm gallons). Holly expects to generate at least 70,000 credits annually through 2010; approximately 88,000 credits generated in 2006

Definitions BPD: the number of barrels per day of crude oil or petroleum products. Catalytic reforming: a refinery process which uses a precious metal (such as platinum) based catalyst to convert low octane naphtha fractionated directly from crude oil to high octane gasoline blendstock and hydrogen. The hydrogen produced from the reforming process is used to desulfurize other refinery oils and is the main source of hydrogen for the refinery. EBITDA1: 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 provided for under 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. Pro Forma EBITDA ('03-'05 Prices)1: 2003-2005 actual trailing prices and/or margins applied to expected current and/or future production Gas Oil Hydrocracker: a refinery process which use catalyst at high pressure, temperature and in the presents of hydrogen to convert high boiling point hydrocarbons to light transportation fuels and low sulfur FCC feedstock Hydrodesulfurization: to remove sulfur and nitrogen compounds from oil in the presence of hydrogen and a catalyst at relatively high temperatures. When we use Pro Forma EBITDA in this presentation, we have adjusted EBITDA by applying actual trailing prices and/or margins for the indicated periods to expected current and/or future levels of production for the indicated periods. EBITDA or Pro Forma 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. Our EBITDA measures are not necessarily comparable to similarly titled measures of other companies. EBITDA measures are presented here because EBITDA 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. Our historical EBITDA is reconciled to net income under "Reconciliations to Amounts Reported under Generally Accepted Accounting Principles" following Item 7A of Part II of our 2005 Report on Form 10-K.

Definitions LSG: gasoline that contains less than 30 PPM of total sulfur. MMSCFD: million standard cubic feet per day PPM: parts-per-million. Refining gross margin or refinery gross margin: the difference between average net sales price and average costs of products per barrel of produced refined products. This does not include the associated depreciation, depletion and amortization costs. Solvent deasphalter / residuum oil supercritical extraction ("ROSE"): a refinery process that uses a light hydrocarbon like propane or butane to extract non asphaltene heavy oils from asphalt or atmospheric reduced crude. These deasphalted oils are then further converted to gasoline and diesel in the FCC process. The remaining asphaltenes are either sold, blended to fuel oil or blended with other asphalt as a hardener. SRU or sulfur recovery unit: a refinery process which converts hydrogen sulfide to elemental sulfur for sale] ULSD or ultra low sulfur diesel: diesel fuel that contains less than 15 PPM of total sulfur.
