                RATIO OF EARNINGS TO COMBINED FIXED CHARGES AND
                           PREFERRED STOCK DIVIDENDS

    For purposes of these computations, earnings consist of income before income
taxes and fixed charges excluding capitalized interest. Fixed charges consist of
interest expense, including amortization of debt discount and financing costs,
capitalized interest, the portion of rental expense which LDNG believes is
representative of the interest component of rental expense.
