(1) Pro forma basic and diluted earnings per share computations are based on the
    weighted-average common stock outstanding and include the dilutive effect of
    stock options using the treasury stock method (using the initial offering
    price of $13.50 per share for periods prior to the initial public offering.
    Common stock outstanding used to compute the weighted-average shares was
    retroactively adjusted for the (i) 1996 exchange of shares resulting from
    the merger of affiliated companies; (ii) 1997 conversion of nonvoting to
    voting stock; (iii) 1997 1-for-2.5 reverse stock split; (iv) acquisition of
    entities under common control during the quarter ending March 31, 1998; and
    (v) Dumpsters and RTS mergers accounted for as poolings-of-interests during
    the quarter ending June 30,1998.

The Company's S Corporation status was terminated on May 8, 1997 and,
accordingly, the Company became fully subject to federal and state income taxes
on May 9, 1997. Pro forma net income and earnings per share amounts have been
computed as if the Company was subject to federal and all applicable state
corporate income taxes for the three months and six months ended June 30, 1998.
Prior to the mergers, Dumpsters and RTS had elected S-Corporation status for
income tax purposes. The recognition of the cumulative deferred tax provision
associated with Dumpsters' and RTS's conversions from S Corporations to a C
Corporations was immaterial to the Company's consolidated financial statements.
