          MidSouth Bancorp, Inc. 3rd Quarter 2004 Earnings Up 12.6%

    LAFAYETTE, La., Oct. 28 /PRNewswire-FirstCall/ -- MidSouth Bancorp, Inc.
(Amex: MSL) ("MidSouth") announced third quarter 2004 net income of
$1,954,000, a 12.6% increase over the $1,735,000 for the third quarter of 2003
and up 12% over second quarter 2004 net income of $1,745,000.  Basic earnings
per share were $.61 for the quarter ended September 30, 2004, up from the
$.55 per share for the third quarter of 2003, and the $.55 per share in the
second quarter of 2004.  Diluted earnings per share were $.59 for the third
quarter of 2004 compared to $.52 per share for the third quarter of 2003 and
$.52 per share for the second quarter of 2004.
    Earnings for the nine months ended September 30, 2004 were $5,360,000,
which is a $692,000 or 14.8% increase over the $4,668,000 in earnings for the
nine months ended September 30, 2003.  Basic earnings per share were $1.68 for
the first nine months of 2004 versus $1.47 for the first nine months of 2003.
Diluted earnings per share were $1.61 and $1.41, respectively.
    Net income increased $219,000 in the third quarter of 2004 compared to the
third quarter of 2003, primarily due to increases in both net interest income
of $271,000 and non-interest income of $386,000, including $120,000 in gains
on sales of securities.  These increases were partially offset by a $430,000
increase in non-interest expenses.  The increased net interest income resulted
from a $546,000 or 9% increase in interest income, partially offset by a
$275,000 or 24% increase in interest expense on deposits.  The improvement in
interest income resulted from a 15% increase in average earning assets for the
third quarter of 2004 compared to the third quarter of 2003.  Interest expense
increased due to a $43.1 million or 15% increase in the average volume of
interest-bearing deposits, resulting primarily from the addition of
approximately $45 million in interest-bearing deposits added through a deposit
campaign from March 2004 through May 2004.  Non-interest income, excluding
gains on sales of securities, increased primarily due to a $396,000 increase
in fees and service charges resulting from a higher volume of demand deposit
accounts.  Non-interest expense increased in quarterly comparison primarily
due to a $244,000 increase in salaries and benefit costs.
    Gains on sales of securities totaled $130,000 for the third quarter of
2004, an increase of $120,000 over the $10,000 in gains reported for the third
quarter of 2003.  The increase resulted almost entirely from the sale of a
correspondent bank's common stock back to the issuing bank in July of 2004.
MidSouth no longer utilized any services with the bank and therefore
liquidated its stock position.  The $128,000 gain on sale of the common stock
brought year-to-date gains on sales of securities to $132,000 at September 30,
2004 compared to $98,000 at September 30, 2003.  Sales of $6.5 million in
available-for-sale securities in 2003 netted MidSouth the $98,000 gain and
allowed improvement of the overall yield on the securities sold as they neared
maturity.
    Compared to the prior quarter ending June 30, 2004, third quarter 2004 net
income increased $209,000 or 12%.  In comparing the two quarters, net interest
income increased $310,000 and non-interest income increased $323,000.  The
increase in non-interest income resulted from the $128,000 gain on sale of
securities and a $215,000 increase in fees and service charges on deposit
accounts.  An increase in the provision for loan losses of $60,000 partially
offset the increase in earnings over prior quarter and resulted from a
reduction in the Allowance for Loan Losses ("ALL") at Financial Services of
the South ("FSS"), MidSouth's finance company subsidiary during the second
quarter of 2004.  The ALL was lowered at the finance company due to the
minimal amount of loans remaining for liquidation.  Increased non-interest
expenses in salaries and benefits ($161,000), legal and professional fees
($50,000), and marketing expenses ($63,000) partially offset the quarterly
improvement in net interest and non-interest income.
    For the nine months ended September 30, 2004 compared to 2003, net income
increased $692,000 or 15%.  Net interest income improved $1,048,000 or 7% due
to increased interest income on a higher volume of earning assets partially
offset by an increase in interest expense on deposits.  Increases of $779,000
in fees and service charges on deposit accounts and $120,000 in ATM/Debit card
income was partially offset by a $254,000 decrease in other non-interest
income categories, primarily Visa merchant income ($193,000) and mortgage loan
processing fees ($140,000).  In the third quarter of 2003, MidSouth outsourced
its Visa merchant processing to First Data Corporation.  The resulting
reduction in Visa merchant income is offset by a $179,000 decrease in Visa
merchant processing expenses that resulted from the processing change and is
reflected in the change in other non-interest expense in year-to-date
comparison.  Salaries and employee benefits increased $456,000 and occupancy
expenses increased $155,000, offsetting the decrease in Visa merchant
processing expenses.

     Highlights for the Quarter Ended September 30, 2004
     --  Return on average equity was 22.46% for the third quarter of 2004
         compared to 21.90% for the third quarter of 2003.  The leverage
         capital ratio was 9.66% at September 30, 2004 compared to 8.51% at
         September 30, 2003 due to the issuance of $8 million in additional
         junior subordinated debentures in September 2004.
     --  Net income for 2004 is up 12.6% in quarterly comparison and 14.8% in
         year-to-date comparison over 2003 net income.
     --  Total loans grew $47.2 million or 19%, from $246.9 million at
         September 30, 2003 to $294.1 million at September 30, 2004, primarily
         in commercial loans.
     --  Nonperforming assets, including loans 90 days or more past due, as a
         percentage of total assets decreased from .34% at September 30, 2003
         to .17% at September 30, 2004.  Year-to-date net charge-offs to total
         loans remained constant at .17% for both periods.
     --  Total consolidated assets increased $82.4 million or 19.6%, from
         $419.9 million at the end of the third quarter of 2003 to
         $502.2 million at the end of the third quarter of 2004.  Total
         deposits increased $69.7 million or 18.6%, from $374.1 million at
         September 30, 2003 to $443.8 million at September 30, 2004.  The
         increase resulted primarily from approximately $50 million in
         deposits resulting from a deposit growth campaign that began in
         March 2004.  The campaign introduced MidSouth's new Platinum Money
         Market account for both retail and commercial customers.  Of the
         $50 million in deposits resulting from the campaign, approximately
         $34 million was deposited into the Platinum Money Market and other
         savings accounts at an average rate of 2.05%.
     --  On October 1, 2004, MidSouth completed a merger with Lamar Bancshares
         of Beaumont, Texas.  At closing, Lamar Bank had assets of
         approximately $115 million and six banking offices in southwest
         Texas.  The Company's banks, MidSouth Bank and Lamar Bank will
         continue to operate as separate subsidiaries under MidSouth Bancorp,
         Inc.
     --  MidSouth continued to work on expansion plans for the Louisiana
         market during the third quarter of 2004, with the new facility on
         Moss Street completed and property purchased to build a full service
         facility in Houma.  Additionally, MidSouth announced that it will
         also open a new location on Johnston Street in the heart of Lafayette
         and will construct an office in the Town Square of the traditional
         neighborhood development of River Ranch, bringing the total number of
         offices in its home base to nine.  In the Texas market, MidSouth
         plans to build new Lamar Bank offices in Conroe and College Station,
         Texas, and plans to continue expansion in the north Houston and
         Woodlands area.

    On October 14, 2004, MidSouth announced a five-for-four (25%) stock split
on its common stock to holders of record as of October 29, 2004 payable on
November 30, 2004.  The Board of Directors also announced that it would
continue its quarterly dividend at $.06 per share and awarded an additional
$.06 Special Dividend to be paid on its common stock on January 4, 2005 to
holders of record as of December 15, 2004.  This will result in a total of
$.12 per share to be paid to shareholders on January 4, 2005.
    MidSouth's common stock is traded on the American Stock Exchange under the
symbol MSL.
