Jacksonville  Bancorp,  Inc.,  reported  quarterly net earnings of $198,000,  or
$0.13 per basic and diluted  share,  in the second  quarter of 2003,  increasing
from $94,000 or $0.07 per share for the second quarter 2002.  Earnings on a year
to date  basis of  $251,000  reflect a 74%  increase  from the 2002 year to date
total of $144,000.

"Our rate of growth continues to be remarkable and is an excellent  indicator of
how well The Jacksonville Bank has been accepted by the Jacksonville community,"
stated Gilbert J. Pomar, III, President and Chief Executive Officer.  "The solid
financial results and incredible growth of this quarter further  demonstrate our
confidence that we are building a strong banking force in  Jacksonville.  We are
still actively  negotiating  workout  agreements with the two borrowers noted as
issues,  and for which specific reserves were recorded,  in the first quarter of
2003.  While these  negotiations  are focused on  maximizing  collection  of the
debts, we also continued to strengthen the loan loss reserve."

Second  quarter 2003 net  interest  income  increased  45% to  $1,376,000,  from
$947,000 in 2002,  primarily due to  significant  new loan volume.  Net interest
margin remained  relatively  steady at 3.82%, as interest income for the quarter
increased to $2,157,000, up 34% from $1,611,000 for the 2002 period, and average
net loans increased 53% from $84.0 million to $128.6 million.  Interest  expense
rose just 18%,  from  $664,000  to  $781,000,  with a 53%  increase  in  average
interest  bearing  liabilities.  The provision for loan losses  increased 61% to
$222,000 for the quarter from $138,000 for second quarter 2002,  reflecting both
the rapid growth of the portfolio and the further strengthening of the reserve.

Noninterest  income  increased  by 72% over second  quarter  2002,  as decreases
created by the Company's  changes in the bankcard  merchant  program become less
significant over time.  Noninterest expense increased by 34% over the prior year
period,  due  primarily to increased  compensation,  professional  fees,  annual
meeting,  and other costs  necessary to support asset growth and further advance
the Company's presence.

Total  assets  increased  40% to $164.9  million at June 30,  2003,  from $117.7
million  at June 30,  2002.  Total  loans and  deposits  increased  49% and 44%,
respectively,  with net loans of $134.3  million at June 30, 2003, up from $90.3
million at June 30,  2002,  and  deposits  rising to $151.5  million from $105.3
million. Further, in comparing second quarter 2003 to first quarter 2003, assets
increased by $17.6 million,  with loans and deposits  increasing $11.9 and $21.4
million respectively.
