Definitions Gross refining margin - Refining revenues less refining cost of products sold Pre-tax margin - Income before income taxes divided by sales and other revenues Return on assets - Net income divided by total assets Return on invested capital - New income divided by the sum of total stockholders' equity plus debt. Debt includes long-term debt, including current maturities, and borrowings under the Company's credit agreement. Debt to total capitalization - Debt divided by the sum of total stockholders' equity plus debt.

Definitions Earnings Before Interest, Taxes, Depreciation and Amortization - Three and Nine Months Ended September 30, 2003 (in thousands) Net Income $17,550 $47,134 Add provision for income tax 11,104 29,343 Add interest expense 755 1,292 Subtract interest income (82) (385) Add depreciation & amortization 9,104 26,029 EBITDA $38,431 $103,413 Earnings before interest, taxes, depreciation and amortization - EBITDA is calculated as net income plus (i) interest expense, (ii) less interest income, (iii) plus income tax provision, and (iv) plus depreciation, depletion and amortization. EBITDA is not a calculation based upon generally accepted accounting principles; however, the amounts included in the EBITDA calculation are derived from amounts included in the consolidated financial statements of Holly. EBITDA should not be considered as an alternative to net income or operating income, as an indication of operating performance of Holly 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 enhances an investor's understanding of Holly's ability to satisfy principal and interest obligations with respect to Holly's indebtedness and to use cash for other purposes, including capital expenditures. EBITDA is also used by Holly management for internal analysis and as a basis for financial covenants. EBITDA is reconciled to net income in the table above. Three Months Nine Months
