                                 STRATEGIC FOCUS

     In an effort to improve  long-term  shareholder  value, the Company has set
earnings per share targets that significantly exceed prior targets. In addition,
the Company has internally  communicated strategies and tactics designed to help
achieve those targets. The following are selected long-term  performance targets
set by the Company:

o    Focus on the core  profitability  of the Company  over the next 3-to-5 year
     period.
o    Achieve  operating  Return on Average  Equity of  13%-to-15%  within 3-to-5
     years.
o    Strive for a Tangible Efficiency Ratio below 50% by the end of the period.
o    Targeted  annual  growth  rates  throughout  the 3-to-5  year period are as
     follows:
     1.   Loan growth of 7%-to-10% annually.
     2.   Deposit growth of 2%-to-4% annually.
     3.   Double-digit growth in operating earnings per share.

     IBERIABANK  maintains a customer  relationship focus.  Decision-making made
closer to the client and  customization  of customer  needs are two  elements in
this  strategy.  Tactical  plans to help achieve  targeted  performance  include
channel/client  profitability  measurement,  segmentation strategies,  deepening
current client  relationships,  fair product/service  pricing,  diligent expense
management, and balance sheet optimization strategies.

     (a)      New Leadership Team

     A new leadership team is in place at the Company. Daryl Byrd, President and
Chief  Executive  Officer of IBERIABANK,  joined the  organization in July 1999.
Since joining the Company,  Byrd has flattened the organizational  structure and
replaced a number of senior  officers  with  seasoned  commercial  bank leaders.
Recent hires include:

     o        Patrick Trahan, Lafayette President
     o        Taylor Barras, New Iberia President
     o        Michael Brown, New Orleans President
     o        George Becker, Monroe President
     o        Barry Mulroy, Chief Administrative Officer
     o        John Davis, Chief Strategic Planning Officer

     IBERIABANK has implemented a new Mission  Statement to provide  guidance to
the  various  constituencies  of the  Bank.  These  constituencies  include  the
Company's  employees,  clients,   shareholders,  and  communities.  The  Mission
Statement describes the Company's goals, objectives, and strategies.


                          EPS RANGES FOR 2000 AND 2001

     Many  controllable  and  uncontrollable  factors  influence  actual  versus
anticipated performance. There can be no assurances that stated "comfort ranges"
for  operating   performance  will  be  achieved.   In  addition,   management's
expectations  may  change  from  time to time as  operating  conditions  change.
However,  the Company's  management  felt  compelled to provide  guidance to the
investment community regarding the Company's current operating EPS expectations.

     Operating EPS for 1999 was reported on January 28, 2000 as $1.79 per share.
Management has stated it is currently  comfortable with estimated  operating EPS
for the year 2000 in the range of $2.10 to $2.15. This range equates to a 17% to
20%  increase  over  1999  operating  EPS.  Based  on the  closing  price of ISB
Financial Corporation's common stock of $13.625 on February 16, 2000, this price
equates  to a  Price/Earnings  Ratio of  between  6.4 and 6.5  times  forecasted
operating EPS for 2000.

     Management has stated it is currently  comfortable with estimated operating
EPS for the year 2001 in the range of $2.35 to $2.45. This range  approximates a
double-digit  increase  over the current  comfort  ranges for  operating EPS for
2000.  Based on the closing  price of the  Company's  common stock of $13.625 on
February 16, 2000, this price equates to a  Price/Earnings  Ratio of between 5.6
and 5.8 times forecasted operating EPS for 2001.

     (b) Actions to Improve Shareholder Value - Restructuring Announcement

     From time to time,  management will take significant actions that are taken
in the best long-term interests of ISB Financial Corporation's stakeholders.  An
example of these actions is the Company's recent  restructuring  announcement on
December 29, 1999. At that time,  the Company  announced a $1.3 million  pre-tax
charge in the fourth quarter of 1999,  aimed at improving  operating  efficiency
and  profitability.  Management  anticipates  future  pre-tax  benefits  of $1.2
million in 2000 and $2 million per year thereafter as a result of this action.

         ACTIONS TO IMPROVE SHAREHOLDER VALUE - SHARE REPURCHASE PROGRAM

     ISB Financial  Corporation  announced  today that the Board of Directors of
the  Company  has  authorized  the  repurchase  of  up  to  300,000  shares,  or
approximately 5% of the Company's outstanding common stock.

     Repurchases  of the  stock are  authorized  to be made from time to time in
open-market transactions as, in the opinion of management, market conditions may
warrant.  Purchases  are expected to begin on or after  February  17, 2000.  The
company  anticipates  purchasing  such  shares  during the next 12  months.  The
repurchased  shares will be held as  treasury  stock and will be  available  for
general corporate purposes, including being available for reissuance pursuant to
the Company's 1996 and 1999 stock option plans.
