                                        Subsidiary, IBERIABANK, To
                                        Acquire 17 Branch Offices

                                        Page 2 of 3

     The 17 branch offices include approximately 48,000 customers or
deposit accounts (including approximately $66 million in demand deposit
accounts).  IBERIABANK will pay a weighted average deposit premium of
approximately 6.45% based upon deposits assumed at the closing date.  In
addition to the branch offices and deposits, IBERIABANK will acquire
approximately 7,800 loans with an aggregate balance of $129 million for a
purchase price equal to the adjusted book value of such loans.  As of
December 31, 1997, the weighted average cost of the to be acquired deposits
was 3.62% and the weighted average yield on the to be acquired loans was
8.74%.

     The transaction is expected to be completed in September 1998 upon
receipt of regulatory approval.  The business day following completion, the
branch offices will open for business fully converted to IBERIABANK offices
and the former First National and Central Bank employees will continue to
staff the offices as IBERIABANK employees.  Larrey G. Mouton, President and
Chief Executive Officer of IBERIABANK, said "We are very excited at the
opportunity to expand our customer base and we look forward to welcoming
these new customers and employees to IBERIABANK in September."  Mr. Mouton
also stated, "This branch office acquisition will significantly advance our
strategy to expand our presence in Louisiana."  

     Upon consummation of the transaction, IBERIABANK's branch office
network will increase to 44 offices in 10 parishes in Louisiana.  Based on
deposits, it is expected that IBERIABANK will rank second in market share
in both the Lafayette and Monroe market areas after closing of the
transaction.  Upon consummation of the acquisition of the branch offices,
the Company anticipates that it will have approximately $1.4 billion in
assets, $1.2 billion in deposits and $805 million in total loans.  The
Company expects the transaction to be accretive to income within the first
year.  Certain condensed pro forma information is provided below.

     ISB Financial Corporation is the holding company for IBERIABANK. 
IBERIABANK currently operates 19 full service offices located in south
central Louisiana and eight full service offices located in the Greater New
Orleans area.  The deposits of IBERIABANK are insured by the Federal

regulation.
