First National, Catawba Valley, First Gaston and Northwestern Banks to
                    Have a New Name, CommunityONE

    ASHEBORO, N.C.--(BUSINESS WIRE)--May 18, 2007--FNB United Corp.
(NASDAQ:FNBN) today announced that effective Monday, June 4, 2007,
First National Bank and Trust Company, including its divisions Catawba
Valley Bank, First Gaston Bank and Northwestern Bank of Wilkesboro,
will change its name to CommunityONE Bank, National Association. The
new name is not the result of a new sale, purchase or merger, and no
community offices are closing.

    "Only our name is changing," stated Michael C. Miller, President
and Chairman of First National. "We're still the same friendly,
hardworking people, serving the financial lives of our customers and
communities, cheerfully and professionally every day. Who we are and
what we do is very much intact."

    The desire for a new name is the result of great growth in recent
years by acquisition, including last year's merger with Integrity
Financial Corporation. While the systems and charters of Integrity's
bank divisions, Catawba Valley, First Gaston and Northwestern, were
merged into First National in August 2006, the bank still operates as
four separate brands.

    "There are three main reasons we decided to change our name," said
Miller. "We wanted a name that was unique from our competition, a name
that better fits our personality, culture and brand promise of Yes You
Can(R) -Yes We Can(R), and a name that embraces and embodies the
diverse sum of our collective parts."

    In addition to the new name, the bank's logo and corporate mascot,
"Jack", has been refined to show some new style and energy. YES!
branding will be expressed in exciting new ways, and First National's
website, www.MyYesBank.com, will serve for all CommunityONE customers
beginning on June 4.

    Bank statements, stationery, checks and business cards will
reflect the new name and logo right away, while signs, merchandising
and marketing materials will be updated gradually over the next
several months. Through it all, business will continue as usual for
customers. Account numbers, checks, loan payments, online banking and
even community office phone numbers will remain the same.

    Commented Miller, "Our name has served us well for the past 100
years, and we look forward to a new century of service as
CommunityONE, a bank that cares about where our customers are going
and goes above and beyond to help them get there."

    Opened in 1907, First National Bank and Trust Company is a North
Carolina-based banking subsidiary of FNB United Corp., and operates 26
community offices as First National Bank, six as Catawba Valley Bank,
