JACKSONVILLE BANCORP ANNOUNCES
                                 RECORD EARNINGS

JACKSONVILLE,  FLA., October  24/PRNewswire-First  Call/--Jacksonville  Bancorp,
Inc. (NASDAQ:  JAXB), holding company for The Jacksonville Bank, announced today
that for the third  quarter in 2007,  the  Company  had record  earnings of $781
thousand,  compared to $677  thousand in 2006.  Earnings per diluted  share were
$0.43, compared to $0.37, an increase of 16.2% over the third quarter 2006.

For the first nine months of 2007, Jacksonville Bancorp reported record earnings
of $2.0  million,  or $1.11 per  diluted  share,  an  increase of 7.7% and 6.7%,
respectively,  over the same 2006 period. Compared to second quarter 2007, third
quarter net income increased 12.5%, while diluted earnings per share rose $0.05,
or 13.2%.  Gilbert J. Pomar,  III,  Jacksonville  Bancorp's  CEO and  President,
stated,  "The Company is  especially  proud of these results when so many in our
industry are facing difficult  times.  Our ongoing  commitment to organic growth
and asset quality has served us well.  We're also  beginning to see results from
our `Deliver the Bank' initiative, which is focused on core deposit growth."

Total assets were $384 million at September  30, 2007,  compared to $326 million
at December 31, 2006 and $319 million at September  30, 2006.  Period-end  loans
increased by $53 million,  or 19% (25%  annualized),  for the nine-month  period
from December 31, 2006,  and by $65 million,  or 24%,  from  September 30, 2006.
Deposits increased by $39 million,  or 15%, from September 30, 2006. The Company
remains  committed  to its  strategy  designed  to attract  and retain  customer
relationships.  Earning assets as a percentage of total assets remained constant
at 96.0% for both periods.

Credit quality  remains  healthy,  with  non-performing  loans at 0.16% of total
loans  outstanding  at  quarter-end  and net  charge-offs  of 0.03% and 0.02% of
average loans for the three- and nine-month periods, respectively. The allowance
for loan  losses  as a  percentage  of loans was 0.91% at  September  30,  2007,
compared to 0.93% a year  earlier.  The  decrease is a result of the quality and
strength of the loan portfolio and management's  analysis of the adequacy of the
reserve  which  would be  required to absorb  estimated  probable  losses in the
Company's  loan  portfolio.  "Recent  news from the  financial  sector  has been
focused  on the  sub-prime  residential  market,  the  residential  construction
industry,  and acquisition and development lending.  Jacksonville Bancorp made a
conscious  decision at  inception  to not enter these  business  lines which has
served us well and,  consequently,  these issues have not affected our Company,"
said Mr. Pomar.

Jacksonville  Bancorp's net interest income for the quarter increased 11.1% over
the third quarter of 2006,  while net interest  income for the first nine months
of 2007 increased 11.7% over the same period of 2006. The increase  reflects the
impact of strong organic loan growth which offset a net interest margin that has
narrowed reflective of the competitive financial markets.

Noninterest  income remained  relatively flat compared to the third quarter 2006
and increased by 10.8% for the nine months ended September 30, 2007, compared to
the previous year. The increase in the nine-month period is primarily the result
of  increased   deposit  service  charges  and  mortgage   origination   income.
Noninterest expense increased by 17.8%,  compared to the quarter ended September
30, 2006.  For the nine months ended  September  30, 2007,  noninterest  expense
increased by 13.9%.  The increases were driven  primarily by the  incremental de
novo  branching  expenses  and an increase in the  assessment  rates  charged to
financial institutions for FDIC insurance.  The new assessment rates, which took
effect on January 1 of this year, primarily impact financial institutions not in
existence on December 31, 1996.
