 (a) The pro forma ratio of earnings to fixed charges for each of the Issuer and
     the Guarantor for the year ended December 31, 1996 give effect to (i) the
     Preferred Stock Refinancing, as defined elsewhere herein, and certain other
     debt refinancings and (ii) with respect to the Guarantor only, the TBS
     Transaction, as if such transactions had occurred at the beginning of 1996.
 
 (b) In connection with the TBS Transaction that occurred on October 10, 1996,
     the Guarantor, formerly a wholly owned subsidiary of the Issuer, acquired
     each outstanding share of capital stock of the Issuer (other than shares
     held directly or indirectly by the Issuer) and became the parent of the
     Issuer. Accordingly, the historical ratios of earnings to fixed charges (or
     coverage deficiencies) of the Issuer and the Guarantor are the same for all
     periods prior to such date because the Issuer is treated for financial
     reporting purposes as the predecessor of the Guarantor.
