                    Southeastern Bank Financial Corp. Reports
                          First Quarter 2007 Earnings


AUGUSTA,  Ga.,  April 20, 2007 - Southeastern Bank Financial Corp. (OTCBB:SBFC),
the  holding  company  for  Georgia Bank & Trust Company of Augusta and Southern
Bank  & Trust, today reported quarterly net income of $2.8 million for the three
months  ended  March  31, 2007, an increase of 12.2 percent from $2.5 million in
the  first  quarter of 2006. Diluted earnings per share for the first quarter of
2007  were  $0.50,  an  8.7 percent increase from $0.46 for the same period last
year.

"We  continued  on  our path of solid, stable growth during the first quarter of
2007,"  said  R. Daniel Blanton, president and chief executive officer. "After a
period  of  expansionary  activity,  our  focus  has  been on consolidating that
development  and  focusing on the fundamentals of community banking - delivering
valuable banking products and services through a friendly, personalized approach
while  supporting  the  communities  in  which  we  operate."

Total  assets  at  March  31,  2007,  were  $1.1  billion, an increase of $185.6
million,  or  20.1  percent, from a year ago, and $66.4 million, or 6.4 percent,
from  Dec.  31,  2006.  Loans  outstanding  at the end of the first quarter were
$774.2  million,  and  total  deposits  were  $874.6 million, an increase of 3.2
percent  and  9.1  percent,  respectively,  from  Dec.  31,  2006.

Net  interest  income  for  the  first quarter of 2007 was $9.1 million, up 13.5
percent  from the same period a year ago. Noninterest income for the quarter was
$3.6  million,  an  increase  of  11.9  percent  over the first quarter of 2006.
Noninterest  expense  was $7.8 million in the first quarter of 2007, an increase
of  $656,899  from  a  year  ago.



Return  on  average assets (ROA) was 1.06 percent for the first quarter of 2007,
and  return  on  average  shareholders'  equity  (ROE)  was  13.97  percent.

"The ongoing growth in our core deposits and loans continues to be driven by the
strength of our markets and our service-oriented approach to community banking,"
said  Blanton.  "The  solid  increase in our noninterest income during the first
quarter  reflects  the  continued  success  of  our  retail investment and trust
service  offerings."
