Exhibit 99.1

Forward-Looking Statements

     This presentation may include forward-looking statements
containing expectations about future conditions and descriptions of
future plans and strategies.  Whitney's ability to accurately predict
the effects of future plans or strategies is inherently limited such that
actual results and performance could differ materially from those set
forth in the forward-looking statements.  Factors that could cause
actual results to differ from those expressed in the forward-looking
statements are available in our Annual Report on Form 10-K for the
year ended December 31, 2004.  Whitney does not intend, and
undertakes no obligation, to update or revise any forward-looking
statements, whether as a result of differences in actual results,
changes in assumptions or changes in other factors affecting such
statements.
