(a) The Company considers one-third of rent expense to be a reasonable estimate of the related interest expense.

(b) Earnings for the three months ended June 30, 2010 were significantly affected by one-time costs related to the Transactions. If earnings were adjusted to exclude the $5.0 million purchase accounting inventory amortization expense, $5.3 million amortization of intangibles and $20.0 million in transaction costs associated with the Transactions, the ratio of earnings to fixed charges for the three months ended June 30, 2010 would be 1.0x.
