(1) Shares used in these tables are weighted based on the number of days the
    shares were outstanding or assumed to be outstanding during each period.
 
(2) On October 31, 1996, Unison acquired American Professional Holding, Inc. and
    Memphis Clinical Laboratory, Inc. in a business combination accounted for as
    a pooling of interests. Unison issued 540,000 common shares in connection
    with these acquisitions. All earnings per share information has been
    restated to reflect these acquisitions.
 
(3) Pursuant to Securities and Exchange Commission Staff Accounting Bulletin No.
    83, "Earnings Per Share Computation in an Initial Public Offering," an
    aggregate of 16,667 common stock purchase warrants issued during the
    twelve-month period prior to the initial public offering, at prices below
    the initial public offering price have been included as if they were
    outstanding in 1995 and 1994. In December 1995, Unison repurchased these
    stock warrants.
 
(4) This calculation is submitted in accordance with Regulation S-K Item
    601(b)(11) although it is contrary to paragraph 40 of APB Opinion No. 15
    because it produces an antidilutive result.
