The ratio of earnings to fixed charges has been calculated by dividing income
before income taxes and fixed charges by fixed charges. Fixed charges for this
purpose include cash interest expense, amortization of deferred financing costs
and one third of operating lease payments (the portion deemed to be
representative of the interest factor).

(a)   Earnings were inadequate to cover fixed charges by $5,502. This
      shortfall was attributable to the expenses incurred in connection with the
      Recapitalization, including compensation charges of $17,924 for
      bonuses and phantom stock payments and transaction fees and expenses of
      $1,967.

(b)   Earnings were inadequate to cover fixed charges by $370.

(c)   Earnings were inadequate to cover fixed charges by $3,654. This shortfall
      was largely attributable to the write-off of deferred financing costs
      incurred relating to the Bridge Facility.
