(a) Earnings before interest, taxes and amortization of intangibles ("EBITA") is a non-GAAP
financial measure within the meaning of applicable SEC rules and regulations.  
Management uses EBITA as an additional operating performance measure, which excludes
acquisition related amortization expense, because it believes that EBITA is a useful
measure to evaluate the performance of our businesses.  EBITA is not, nor should not be
used as a substitute for Operating Income, as determined in accordance with U.S. GAAP.
