              MIDSOUTH BANCORP, INC. ANNOUNCES 2ND QUARTER EARNINGS

    LAFAYETTE, La., July 26 /PRNewswire-FirstCall/ -- MidSouth Bancorp, Inc.
(Amex: MSL) announced second quarter 2005 net income of $2,040,000 a 16.9%
increase over the $1,745,000 for the second quarter of 2004 and 6.1% over the
first quarter of 2005 net income of $1,923,000. Basic earnings per share were
$.42 for the quarter ended June 30, 2005, compared to $.40 per share reported
for the second quarter of 2004, and $.39 per share earned in the first quarter
of 2005. Diluted earnings per share were $.40 for the second quarter of 2005
compared to $.38 per share for the second quarter of 2004 and $.38 for the first
quarter of 2005.

    Earnings per share data have been adjusted to reflect a 10% stock dividend
on common stock to holders of record on July 29, 2005 and payable on August 19,
2005.

    Year-to-date earnings as of June 30, 2005 totaled $3,964,000, a 16.4%
increase over the $3,406,000 reported for the six months ended June 30, 2004.
Basic earnings per share were $.81 for the first half of 2005 versus $.77 per
share for the first half of 2004. Diluted earnings per share were $.78 versus
$.74, respectively.

     Highlights for the Quarter Ended June 30, 2005
     * Return on average equity was 16.26% for the second quarter of 2005
       compared to 19.78% for the second quarter of 2004. The return on average
       common equity for 2005 was affected by the issuance of stock in
       connection with MidSouth Bancorp, Inc.'s ("MidSouth's") acquisition of
       Lamar Bancshares, Inc., the parent company of Lamar Bank ("Lamar") on
       October 1, 2004. The leverage capital ratio was 9.15% at June 30, 2005
       compared to 8.65% at June 30, 2004.
     * Net interest income totaled $6,857,000 for the second quarter of 2005, up
       35.1% from the $5,074,000 reported for the second quarter of 2004. Net
       interest income increased primarily due to a 30% increase in the average
       volume of earning assets, including the assets acquired from Lamar. The
       impact of the earning asset volume increase was partially offset by rate
       and volume increases in interest-bearing liabilities.
     * Total consolidated assets increased $154.3 million or 32.3%, from $477.6
       million at the end of the second quarter of 2004 to $631.9 million at the
       end of the second quarter of 2005.
     * Total loans grew $130.6 million or 46.7%, from $279.4 million at June 30,
       2004 to $410.0 million at June 30, 2005, primarily in commercial, real
       estate and agricultural credits.
     * Nonperforming assets, including loans 90 days or more past due, totaled
       $2.2 million at June 30, 2005. As a percentage of total assets,
       nonperforming assets remained unchanged at .36% for both June 30, 2004
       and June 30, 2005. Net charge-offs to total loans decreased from .08% to
       .05% for the same periods, respectively. Allowance for loan loss
       provisions totaling $66,000 were taken in the second quarter of 2005
       compared to $190,000 in the second quarter of 2004. The low volume of
       charge-offs and consistent quality within the loan portfolio supported
       minimal provisions for the second quarter of 2005.
     * Total deposits increased $127.5 million or 29.6%, from $431.2 million at
       June 30, 2004 to $558.7 million at June 30, 2005. Other than growth
       attributed to the Lamar acquisition, deposit growth has been primarily in
       MidSouth's Platinum money market accounts introduced in March of 2004.
       Additionally, the core non-interest bearing demand accounts have
       continued to grow and remain approximately 23% of total deposits at June
       30, 2005.

    Most of the growth reflected in balance sheet comparison of second quarter
2005 with second quarter 2004 resulted from the Lamar merger.



    Components of Second Quarter Earnings
    Net interest income for the second quarter of 2005 increased $1.8 million or
35.1% compared to the second quarter of 2004. Of the $1.8 million, approximately
$1.2 million was attributed to the addition of Lamar's net interest income and
the remaining $600,000 was attributed to an increase in MidSouth Bank's net
interest income. Although MidSouth Bank's total interest income increased
approximately $1.4 million due to increased earning asset volume in the second
quarter of 2005, the increase was mostly offset by an $800,000 increase in
interest expense on deposits as compared to second quarter 2004. The increase in
interest expense resulted from a higher average volume of interest-bearing
deposits that are indexed to the 90-day Treasury bill, which increased 177 basis
points over the past 12 months. MidSouth Bank's Platinum Money Market accounts
contributed most of the increase in interest-bearing deposits and represented
approximately $115 million or 21% of total consolidated deposits.

    Non-interest income for the second quarter of 2005 increased $1.1 million
compared to the second quarter 2004. Lamar contributed approximately $574,000 to
the increase in non-interest income, primarily in service charges on deposit
accounts inclusive of insufficient funds fees. Additionally, MidSouth Bank's
service charges on deposit accounts increased $368,000, primarily due to a
higher volume of demand deposit accounts. MidSouth Bank's other non- interest
income increased $177,000 in quarterly comparison primarily due to a $93,000
distribution received from PULSE in connection with its merger with a subsidiary
of Discover Financial Services, Inc.

    Non-interest expense increased $2.6 million from the second quarter of 2004
to the second quarter of 2005, primarily due to Lamar expenses totaling $1.8
million. Lamar's expenses for the second quarter of 2005 included approximately
$128,000 in costs primarily related to its data processing conversion completed
in May of 2005. Of the remaining $.8 million increase in non-interest expenses
at MidSouth Bank, approximately $328,000 was attributed to salaries and
benefits, $125,000 to occupancy expenses, $119,000 to marketing expenses, and
$111,000 to accounting fees for a Sarbanes-Oxley internal controls review
performed in 2005. Management expects the impact of the accounting fees on
earnings to decrease during the second half of 2005 due to a deferment of the
requirement to certify its internal controls, delaying much of the testing phase
until 2006.

    In year-to-date comparison, total net income increased $558,000 or 16.4%.
Lamar's contribution of approximately $265,000 to the increase was effected by
the $128,000 in conversion costs and by approximately $155,000 in related
amortization of core deposit intangibles, net of income taxes.

    MidSouth Bank contributed $493,000 in additional income for the first half
of 2005 compared to 2004, as increases in net interest income of $910,000 and
non-interest income of $1,534,000 offset increased non-interest expenses of
$1,877,154. The increase in non-interest income included a total of $631,000 in
distributions received from PULSE. The increase in non-interest expenses
resulted primarily from increased salaries and benefit costs ($713,000),
accounting fees ($214,000) and occupancy ($199,000), marketing ($272,000) and
education and travel ($93,000) expenses.

    At the parent company level, increased interest expense of $232,000 on trust
preferred securities partially offset the increase in consolidated net income
for the six months ended June 30, 2005.

    During the second half of 2005, MidSouth expects to open four new offices.
Expected timeframes for opening start with the Baton Rouge office in August, the
River Ranch office (Lafayette) in September, and the Conroe, Texas and Houma
offices in October. The Conroe, Texas and Houma offices will replace loan
production offices currently in those markets. Management expects the impact of
fully staffing these new offices will be reflected in third and fourth quarter
expenses and any substantial contributions to income will not be reflected until
2006.

    MidSouth Bancorp, Inc. is a two-bank holding company headquartered in
Lafayette, Louisiana whose wholly-owned active subsidiaries are MidSouth Bank,
N.A., also headquartered in Lafayette, and Lamar Bank, headquartered in
Beaumont, Texas. The MidSouth franchise consists of 24 banking offices and two
