 (a) TBS became a wholly owned subsidiary of the Issuer on October 10, 1996
     through a merger with a subsidiary of the Issuer in connection with the TBS
     Transaction. The ratios of earnings to fixed charges of TBS for all
     post-merger periods have been adjusted to reflect the Issuer's basis of
     accounting. The ratios of earnings to fixed charges (or coverage
     deficiencies) of TBS for all pre-merger periods are reflected at TBS's
     historical cost basis of accounting. Certain reclassifications have been
     made to TBS's ratios of earnings to fixed charges for pre-merger periods to
     conform to the post-merger presentation.
