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
Whitney’s filings with the Securities and Exchange Commission.
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.

Assessment Process

Reviewed all significant criticized loans and $1.1 billion
sample of commercial loans over $1 million

Overlayed results of sample on remaining impacted
portfolio, similar to acquisition due diligence process

Differentiate commercial loans over and under $1
million

Smaller commercial loans segmented by severely
impacted versus lesser impacted areas as well as pre-
storm credit rating and collateral

Consumer loans segmented by credit scores and
collateral

Impact of Storms on Credit Quality

Assessment Process Continued in 4^th Qtr
2005 and 1^st Qtr 2006

Reviewed all criticized loans and all
commercial loans over $250,000 plus some
other smaller loans

Overlayed results of reviewed loans on
remaining impacted portfolio

Consumer loans segmented by credit scores
and collateral as in 3 ^rd Qtr 2005

Impact of Storms on Credit Quality

Assessment Process Will Continue Indefinitely

All criticized loans and larger loans will continue
to be reviewed each quarter

As this process continues, there will be fewer and
fewer unreviewed loans and less need for an
overlay process

Impact of storms on Whitney’s small portfolio of
consumer loans will probably not be evident until
early 2^nd Qtr 2006
