    "Because of our tremendous growth in the past few years, we identified the
need for a strategic marketing discipline involving product development,
market expansion and marketing communication," said MidSouth Bank President
and CEO Rusty Cloutier. "Alex comes to us with tremendous experience in all of
these areas, particularly managing complex strategic and brand initiatives for
financial institutions in several Texas markets. He will focus on sharpening
the MidSouth brand throughout both our Louisiana footprint and southeast
Texas, where we have been building a franchise for more than two years."

    Calicchia has an office in Lafayette but will be based out of Houston,
where MidSouth Bank is opening a banking facility in the next two months at
2930 W. Sam Houston Parkway, in the Kempwood Office Building. In addition to
his ongoing effort to solidify MidSouth Bank's brand position and marketing
strategy, Calicchia will assist the Houston employees, a team led by seasoned
commercial lender Jeffery Vargo, as they work to establish MidSouth Bank as
the premier financial services brand in the market.  "There's an exciting road
ahead for both the bank and our Houston customers," Calicchia said. "We are
fervent competitors with an exceptional product, and we are making a major
commitment to the Houston market," he added. "It will take some time for
people to get to know us, but once they do, I am confident they will like what
they see."

    The new CMO is also assisting in the ongoing development of the banking
group's suite of products and services.

    Calicchia's 23-year career in marketing and advertising includes work in
New Orleans, Houston, Dallas and New York. Most of his experience is in the
field of banking, having previously served as Vice President, Brand and
Product Marketing Manager for Capital One. He worked out of the company's New
Orleans and Houston offices and led the strategic marketing and brand
initiatives for the $32-billion-asset bank with 330 retail locations. He also
played a key role in the conversion of Hibernia National Bank to the Capital
One retail brand.

    Prior to joining Capital One, Calicchia was Senior Vice President,
Corporate Marketing Manager and Retail Product Development Manager for more
than five years at Amegy Bank in Houston. He oversaw all marketing functions
for the $7 billion bank with 70 banking centers in Houston and Dallas and also
was in charge of retail product development -- both consumer and small
business.

    After graduating from the University of Texas at Austin with a bachelor's
degree in advertising in 1984, Calicchia entered the fast-paced world of
advertising, first as an Assistant Media Planner with McCann Erickson in
Houston and then as a Senior Media Planner with The Richards Group in Dallas.
He later worked in New York as an Account Executive for Bankers Monthly, one
of the most respected financial services publications in the country. In 1989
he returned to his hometown to serve as Director of Advertising for Retail
Concepts, Inc., segueing his agency experience to the corporate side for this
national chain of specialty stores.
