             NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - FINANCIAL STATEMENTS

In management's  opinion,  the  accompanying  unaudited  consolidated  financial
statements  contain  all  adjustments   (consisting  of  only  normal  recurring
adjustments)  considered  necessary for a fair  statement of the results for the
interim  periods  presented.  The  results of  operations  for the period  ended
February 29, 2000 are not  necessarily  indicative of the results to be expected
for the full year. The interim consolidated  financial statements should be read
in  conjunction  with  the  Lifemark   Corporation   ("Lifemark"  or  "Company")
consolidated  financial  statements and notes thereto  included in the Company's
Form 10-K for the year ended May 31, 1999.

NOTE 2 - NET INCOME PER SHARE

Basic net income per share is computed by  dividing  net income by the  weighted
average number of common shares  outstanding  during each period. Net income per
share  assuming  dilution is computed  by  dividing  net income by the  weighted
average  number of common  shares  outstanding  during the period  after  giving
effect to dilutive  stock options and warrants and adjusted for dilutive  common
shares assumed to be issued on conversion of the Company's convertible loans.

The following is the  computation  of the  reconciliation  of the numerators and
denominators  of net income  per common  share - basic and net income per common
share - assuming  dilution in accordance with Statement of Financial  Accounting
Standards No. 128, "Earnings Per Share".
