                  FNB United Corp. Sells Credit Card Portfolio

     FNB  United  Corp.  (NASDAQ:  FNBN),  parent of  CommunityONE  Bank,  N.A.,
announced  continued progress in its integration of recent  acquisitions  United
Financial,  Inc.,  and  Integrity  Financial,  Inc. As part of the  integration,
CommunityONE  Bank has sold its  credit  card  portfolio,  along  with  multiple
portfolios  acquired  from former  Integrity  and United  subsidiaries,  to Elan
Financial Services, a division of US Bank (NYSE: USB).

     As a result of the sale,  FNB United  Corp will  recognize  a $1.3  million
non-recurring  gain which will be reported  with its third quarter  results.  Of
that amount,  $1.0 million will be from the sale of the  portfolio  and $300,000
resulting  from the recapture of the allowance for loan loss reserve  associated
with the $4.0 million sold portfolio.  Concurrently, a $250,000 expense has been
recognized to cover the buyout of two of the unexpired contracts with Visa.

     "This new partnership with Elan will significantly  increase the number and
quality of credit card offerings to the Bank's retail and commercial customers,"
said Mark  Hensley,  CommunityONE  Chief Banking  Officer.  "We will be far more
competitive in the credit card arena than we've ever been. Retail customers will
be provided with seven different products, including Visa Platinum, Secured Visa
and Visa Signature  products.  Four different products will be made available to
commercial  customers,  and both the  retail  and  commercial  offerings  have a
variety of rewards programs. These improved programs will permit CommunityONE to
increase fee income through a revenue sharing  arrangement  with Elan on current
and new cards."

     "The  unification  of credit card programs is an example of the progress we
are making in bringing these companies  together as a single team," said Michael
C. Miller, FNB United President.  "We are improving product offerings and at the
same time reducing expense, operating more efficiently, and reducing risk."

     FNB United Corp. is the central North  Carolina-based  bank holding company
for  CommunityONE  Bank,  N.A.  Opened  in  1907,  CommunityONE  (MyYesBank.com)
operates  forty-three  offices  in 35  communities  throughout  North  Carolina.
Through its subsidiary, FNB United offers a complete line of consumer,  mortgage
and business banking services; including loan, deposit, cash management,  wealth
management and internet banking services.
