ASSUMING FULL DILUTION:
Consolidated income applicable to Ogden common stock        $ 10,777   $  9,288

Note:

      Earnings per common share was computed by dividing income, increased
      (decreased) for adjustments arising from minority interest in consolidated
      subsidiaries, reduced by preferred stock dividends requirements, by the
      weighted average of the number of shares of common stock and common stock
      equivalents, where dilutive, outstanding during each period.

      Earnings per common share, assuming full dilution, was computed on the
      assumption that all convertible debentures, convertible preferred stock,
      and stock options converted or exercised during each period, or
      outstanding at the end of each period were converted at the beginning of
      each period or the date of issuance or grant, if dilutive. This
      computation provides for the elimination of related convertible debenture
      interest and preferred dividends.
