Forward-Looking Statements Contained Herein

Statements  in this  release  concerning  the  Company's  future  prospects  are
"forward-looking  statements" under the Private Securities Litigation Reform Act
of 1995.  There can be no assurances  that future results will be achieved,  and
actual results could differ  materially from forecasts and estimates.  Important
factors  that could  cause  actual  results to differ  materially  include:  the
significant  percentage of CA's quarterly sales consummated in the last few days
of the quarter making financial  predictions  especially difficult and raising a
substantial risk of variance in actual results;  changes in industry  accounting
guidance; the risks associated with changes in the company's business model; the
risks  associated  with  changes in the way in which the  company  accounts  for
license revenue; the difficulties of compiling pro forma financial  information,
given  acquisitions  over  time;  instability  resulting  from  changes  to  the
company's business model; the emergence of new competitive initiatives resulting
from rapid technological advances or changes in pricing in the market; the risks
associated with new product introductions as well as the uncertainty of customer
acceptance of these new or enhanced  products from either CA or its competition;
risks associated with the entry into new markets such as professional  services;
the  risks   associated   with   integrating   newly  acquired   businesses  and
technologies;  increasing  dependency  on large dollar  licensing  transactions;
delays in product delivery;  reliance on mainframe  capacity growth; the ability
to  recruit  and  retain  qualified   personnel;   business  conditions  in  the
distributed systems and mainframe software and hardware markets; uncertainty and
volatility  associated with Internet and eBusiness  related  activities;  use of
software patent rights to attempt to limit competition;  fluctuations in foreign
currency  exchange rates and interest rates; the volatility of the international
marketplace;  uncertainties  relative to global economic  conditions;  and other
risks described in filings with the Securities and Exchange Commission.
