                    SOUTHEASTERN BANK FINANCIAL CORP. REPORTS
                       RECORD SECOND QUARTER 2007 EARNINGS

AUGUSTA, GA., JULY 27, 2007 - Southeastern Bank Financial Corp. (OTCBB:SBFC),
the holding company for Georgia Bank & Trust Company of Augusta and Southern
Bank & Trust of Aiken, S.C., today reported record quarterly net income of $3.0
million for the three months ended June 30, 2007, a slight increase from $2.9
million in the second quarter of 2006. Diluted earnings per share for the second
quarter of 2007 were $0.54, a slight decrease from $0.55 for the same period
last year.

Total assets at June 30, 2007, were $1.1 billion, an increase of $195.4 million,
or 20.8 percent, from a year ago, and $92.1 million, or 8.8 percent, from
December 31, 2006. Loans outstanding at the end of the second quarter were
$809.6 million, and total deposits were $898.1 million, an increase of 8.0
percent and 12.0 percent, respectively, from December 31, 2006.

"We continued to grow our asset base in the second quarter, which is up nearly
nine percent since the beginning of the year," said President and Chief
Executive Officer R. Daniel Blanton. "Contributing to this increase was our
Southern Bank & Trust affiliate in Aiken, S.C., which has grown to $60 million
in assets.

"While earnings in the second quarter were only slightly ahead of a year ago, we
faced a tough comparison with a record second quarter of 2006. Yet, we still
managed to grow income more than six percent year-to-date over 2006, and we also
generated solid growth in net interest income."

Net interest income for the second quarter of 2007 totaled $9.5 million, a 12.4
percent increase from $8.4 million for the same period of 2006. Noninterest
income for the quarter totaled $3.8 million, relatively unchanged from a year
ago. Noninterest expense was $7.6 million, a 5.0



percent  increase from a year ago, primarily due to costs related to the growth
of Southern Bank & Trust.

Annualized return on average assets (ROA) was 1.06 percent for the second
quarter of 2007, and annualized return on average shareholder's equity (ROE) was
14.19 percent.

Net income for the six months ended June 30, 2007, totaled $5.7 million, a 6.4
percent increase over the $5.4 million reported in the same period of 2006.
Diluted earnings per share for the first six months of 2007 were $1.04, an
increase of 3.0 percent from $1.01 per share earned in the same period a year
ago.

Net interest income for the first six months of 2007 was $18.5 million, up 12.9
percent from the $16.4 million in the first six months of 2006. Noninterest
income was $7.4 million for the first six months of 2007, an increase of 5.2
percent from $7.1 million in the same period of 2006. Noninterest expense was
$15.4 million for the six month period, compared to $14.4 million in 2006.

"Our allowance for loan losses is up almost $1.4 million since the end of 2006,
due to robust loan growth and some softening in asset quality. Our
non-performing assets increased $1 million since December 31, 2006 even though
net chargeoffs were only $137,000 during the first six months of 2007.  We still
compare very favorably to our peer group of banks," said Blanton. "We remain
confident that we can maintain a solid level of credit quality moving forward."
