          MidSouth Bancorp, Inc. Reports 3rd Quarter Earnings Up 40%@



    LAFAYETTE, La., Oct. 27 /PRNewswire-FirstCall/ -- MidSouth Bancorp, Inc.
(Amex: MSL) ("MidSouth") announced net income of $1,734,567, a 40% increase
over the $1,241,673 for the third quarter of 2002 and a 7% increase over the
second quarter 2003 earnings of $1,624,141.  Basic earnings per share were
$.55 for the quarter ended September 30, 2003, a significant increase from the
$.39 per share reported for the third quarter of 2002, and up four cents
($.04) from the $.51 per share reported for the second quarter of 2003.
Diluted earnings per share were $.52 for the third quarter of 2003 compared to
$.38 per share for the third quarter of 2002 and $.49 for the second quarter
of 2003.  On August 29, 2003, MidSouth paid a 10% stock dividend on its common
stock to holders of record on July 31, 2003.  Earnings per common share data
have been adjusted accordingly.

    Earnings for the nine months ended September 30, 2003 were $4,668,260, a
$1,521,211 or 48% increase over the $3,147,049 for the nine months ended
September 30, 2002.  Basic earnings per share were $1.47 for the first nine
months of 2003 compared to $.99 for the first nine months of 2002.  Diluted
earnings per share were $1.41 and $.97, respectively.

    Substantial declines in interest expense and loan loss provisions
accounted for the increases in quarterly and year-to-date comparisons.


     Highlights for the Quarter Ended September 30, 2003
     --  Return on average equity was 21.90% for the third quarter of 2003
         compared to 18.92% for the third quarter of 2002.  The leverage
         capital ratio was 8.51% at September 30, 2003 compared to 8.24% at
         September 30, 2002.
     --  Net interest income totaled $5,112,838 for the third quarter of 2003,
         up 11% from the $4,589,399 reported for the third quarter 2002.  Net
         interest income increased primarily due to a substantial decline in
         interest expense combined with a slight increase in interest income
         due to an increase in the average volume of earning assets.
     --  A decrease in the provision for loan losses of $179,250 boosted
         earnings for the quarter ended September 30, 2003.  A provision
         totaling $250,000 was expensed during the third quarter of 2003
         compared to the $429,250 expensed during the third quarter of 2002.
     --  Total loans grew $11.8 million or 5%, from $235.1 million at
         September 30, 2002 to $246.9 million at September 30, 2003.
     --  Nonperforming assets as a percentage of total assets decreased from
         .27% at September 30, 2002 to .22% at September 30, 2003.  Net
         charge-offs to total loans decreased from .35% to .17% for the same
         periods, respectively.
     --  Total consolidated assets increased $37.6 million or 10%, from
         $382.2 million at the end of the third quarter of 2002 to
         $419.8 million at the end of the third quarter of 2003.
     --  Total deposits increased $31.5 million or 9%, from $342.6 million in
         the third quarter of 2002 to $374.1 million in the third quarter of
         2003.  The increase resulted primarily from deposits associated with
         a public fund contract.  The contracted funds were deposited on
         July 1, 2003 and averaged $26.9 million for the third quarter of
         2003.
     --  MidSouth increased dividends paid on its common stock by 32% with a
         10% stock dividend paid on August 29, 2003 and an increase in cash
         dividends from five cents ($.05) to six cents ($.06) per common share
         for the quarter ended September 30, 2003.
     --  MidSouth was recognized in the US Banker as one of the top publicly
         traded community banks in the country based on a three year average
         return on equity.
