Forward-Looking Statements

This statement may contain certain "forward-looking statements" with respect to
certain of Prudential's plans and its current goals and expectations relating to
its future financial condition, performance, results, strategy and objectives.
Statements containing the words "believes", "intends", "expects", "plans",
"seeks" and "anticipates", and words of similar meaning, are forward-looking. By
their nature, all forward-looking statements involve risk and uncertainty
because they relate to future events and circumstances which are beyond
Prudential's control including among other things, UK domestic and global
economic and business conditions, market related risks such as fluctuations in
interest rates and exchange rates, and the performance of financial markets
generally; the policies and actions of regulatory authorities, the impact of
competition, inflation, and deflation; experience in particular with regard to
mortality and morbidity trends, lapse rates and policy renewal rates; the
timing, impact and other uncertainties of future acquisitions or combinations
within relevant industries; and the impact of changes in capital, solvency or
accounting standards, and tax and other legislation and regulations in the
jurisdictions in which Prudential and its affiliates operate. This may for
example result in changes to assumptions used for determining results of
operations or re-estimations of reserves for future policy benefits. As a
result, Prudential's actual future financial condition, performance and results
may differ materially from the plans, goals, and expectations set forth in
Prudential's forward-looking statements. Prudential undertakes no obligation to
update the forward-looking statements contained in this statement or any other
forward-looking statements it may make.
