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.

A Strong Monitoring Process Is Key

One of our core strengths is understanding and
managing credit risk

– Consistent application and monitoring of standards
throughout the Company

– Multiple controls within our credit culture

– An independent credit review function assesses the
accuracy of officer ratings, timeliness of rating
changes, performs concurrent reviews

loans leads to increased level of
downgrades, criticized and
nonperforming loans

• 5% of total loans are criticized

• Approximately 1/3rd of the
criticized are lots and
undeveloped land

– 6% AL/MS loans are criticized

Adequately Reserved For Inherent Loss

• Methodology for determining the allowance is a consistent process

– Important factors are re-evaluated quarterly to respond to changing conditions

• Allowance encompasses three elements

– Allowances established for losses on criticized loans

– Allowances based on historical loss experience

• Loans with acceptable credit quality

• Groups of homogenous loans not individually rated

– Allowances based on general economic conditions

• Allowance is built each quarter from the bottom up in determining loan loss provision

• Based on estimates of the inherent loss in the portfolio, we believe we are adequately
reserved

Reserves/loans %

Historical Trend: Healthy Level of Recoveries

Percent Net Charge-offs to Average Loans

• Higher level in 1Q08 as we
took charge-offs for some of
the inherent losses we
reserved for in earlier
periods

• Net charge-offs historically
at or below peer levels given
a higher level of recoveries
