| (1)   | The interest expense component of rental expense is calculated as one-third of the aggregate rent expense for each year, which is a reasonable approximation of the interest factor. |
|-----------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (2)   | Computed as (y) total earnings available for fixed charges to (z) total fixed charges.  Total earnings available for fixed charges were insufficient to cover fixed charges for the year ended December 31, 2009 by $73.4 million.  As a result, the ratio of earnings to combined fixed charges is not meaningful for 2009. |
