         FOR IMMEDIATE RELEASE                                April 17, 2000

                  BANCORPSOUTH AND FIRST UNITED BANCSHARES
                           ANNOUNCE MERGER AGREEMENT


EL DORADO, Ark. and TUPELO, Miss. - April 17, 2000 - BancorpSouth, Inc. (NYSE:
BXS) and First United Bancshares, Inc. (NASDAQ: UNTD) said today they have
signed a definitive agreement for the merger of BancorpSouth and First United,
which would create a six-state regional financial services company.

Under the terms of the agreement which has been approved by the boards of both
companies, First United stockholders would receive 1.125 shares of BancorpSouth
common stock in exchange for each share of First United stock. The transaction,
based on BancorpSouth's closing stock price of $16.00 on April 14, 2000, values
each First United share at $18.00, or a premium to First United's closing price
on April 14th of approximately 43%, for a total transaction value of
approximately $455 million.

The transaction is expected to be completed in the third quarter of this year
and to be accounted for as a pooling of interests. Approval of banking
regulators and both BancorpSouth and First United shareholders is required. The
transaction is expected to be tax-free for First United stockholders. Each party
has granted the other an option to purchase up to 19.9% of its outstanding
shares in certain circumstances. BancorpSouth expects to incur related after-tax
merger and restructuring charges of approximately $20 million. The merger is
expected to be accretive to earnings in 2001.

First United, based in El Dorado, Ark., at year-end 1999 had $2.7 billion in
assets. It operates 11 affiliate banks and a non-bank subsidiary, First United
Trust Company N.A., from 69 banking locations with approximately 1,000 employees
in Arkansas, Louisiana and Texas. The company has a strong position in the major
markets it serves.

"We are dedicated to our communities, our employees and our shareholders. That
is why this merger is such a good fit. BancorpSouth, like First United, has
always been very close to the people and communities it serves," said James V.
Kelley, Chairman of the Board, President and CEO of First United. "BancorpSouth
serves similar markets in Mississippi, Alabama and Tennessee to the ones we
serve in Arkansas, Louisiana and Texas. The level of technology and


   2

information systems that BancorpSouth brings to this merger would enhance our
ability to identify and meet the needs of our customers. BancorpSouth is an
ideal partner for us."

"First United's dedicated staff has earned a reputation for expertise and
service in its market area. Our similarities are many, and the merging of our
companies is an excellent opportunity for us all. Just like First United, we
take pride in the fact that we are close to the communities we serve," said
Aubrey B. Patterson, Chairman and CEO of BancorpSouth. "We both understand the
importance of building long lasting relationships with our customers. In fact,
our success and profitability depend on our ability to add value in the lives of
our stakeholders - our employees, our shareholders and our customers. By uniting
our energies, our bank will leave a regional footprint over six states."

Kelley would become president and chief operating officer of BancorpSouth after
the merger, while Patterson would continue as Chairman and CEO. On a combined
basis, BancorpSouth would have 13 members on its board of directors, of which
four would come from the current First United Board. The definitive agreement
with regard to the transaction has been signed. Each party performed due
diligence on the other during the week of April 10th. An additional three-week
due diligence period will commence upon the announcement of the transaction
during which either party will have the right to terminate the transaction only
in the event of a material difference in expectations based upon information
presented in the companies' 10-Ks for 1999.

The combined company would have assets of approximately $8.6 billion, deposits
of $7.25 billion and shareholders' equity of $758 million. It would operate in
Alabama, Arkansas, Louisiana, Mississippi, Tennessee and Texas. The merger would
make BancorpSouth the largest Mississippi-based banking company in terms of
total assets.

Headquartered in Tupelo, Miss., BancorpSouth is a financial services company
with $5.8 billion in assets operating 167 banking and mortgage locations and 170
ATMs in 87 Mississippi, Tennessee and Alabama communities. The Company also
provides investment services through its subsidiary, BancorpSouth Investment
Services Inc. and insurance services through BancorpSouth Insurance Services.
BancorpSouth's common stock is traded on the New York Stock Exchange under the
symbol BXS.
