                             SELECTED FINANCIAL DATA

Our selected consolidated financial data as of and for the fiscal years ended
June 30, 1997, 1998 and 1999 have been derived from our consolidated financial
statements included elsewhere in this Annual Report, which have been audited by
Deloitte and Touche, LLP, independent auditors, whose report thereon is also
included elsewhere in this Annual Report. Our selected consolidated financial
data as of and for the six-months ended June 30, 1996 and the years ended
December 31, 1994 and 1995 have been derived from our audited consolidated
financial statements, which are not included in this Annual Report. The selected
consolidated financial data as of and for the six-months ended June 30, 1995 and
the twelve months ended June 30, 1996 are derived from unaudited consolidated
financial statements, which, in the opinion of management, reflect all
adjustments necessary for a fair representation of the respective periods. The
selected consolidated financial data set forth below should be read in
conjunction with Management's Discussion and Analysis of Financial Condition and
Results of Operations and the Consolidated Financial Statements and Notes
thereto elsewhere in this Annual Report. The earnings per share amounts prior to
fiscal year 1998 have been restated to comply with Statement of Financial
Accounting Standards 128 "Earnings per Share" (SFAS 128) as required. For
further discussion of earnings per share and the impact of SFAS 128, see Note 1
to the consolidated financial statements.
