Item 1.01     Entry Into a Material Definitive Agreement

     On  March  31,  2006,  Southeastern  Bank  Financial  Corporation  (the
"Registrant")  completed a trust preferred securities financing in the amount of
$10  million.  See  Item  2.03  below.  In  connection  with  the financing, the
Registrant  entered  into  a Indenture, a Guarantee Agreement and an Amended and
Restated  Declaration of Trust filed as Exhibits 4.1, 4.2 and 4.3, respectively,
to this Report and incorporated herein by reference.

Item 2.03     Creation  of  a Direct Financial Obligation or an Obligation under
              an  Off-Balance  Sheet  Arrangement  of  a  Registrant

     On  March  31,  2006, the Registrant completed a trust preferred securities
financing  in  the  amount  of  $10  million. In the transaction, the Registrant
established  Southeastern  Bank  Financial  Trust II, a Delaware statutory trust
(the  "Trust").  The  Trust  issued and sold $10 million of Preferred Securities
(the "Preferred Securities") in a private placement and issued $310,000 of Trust
common  securities  (the  "Common Securities") to the Registrant. The Trust used
the  proceeds  of  these  issuances  to purchase $10,310,000 of the Registrant's
Junior  Subordinated  Deferrable  Interest  Debentures  due  June  15, 2036 (the
"Debentures"). The Debentures and the Preferred Securities will bear interest at
a  three-month LIBOR rate plus 1.40%, adjusted quarterly. The Debentures are the
sole  assets  of  the  Trust  and  are  subordinate  to  the Registrant's senior
obligations.  Concurrently with the issuance of the Debentures and the Preferred
Securities,  the  Registrant  issued  a  guarantee  related  to  the  Preferred
Securities for the benefit of the holders.

     The  Debentures  may  be  redeemed  after five years, and sooner in certain
specific  events,  including in the event that the financing is not eligible for
treatment  as  Tier  1 capital, subject to prior approval by the Federal Reserve
Board,  if then required. Interest on the Debentures may be deferred at any time
or  from  time  to  time  for  a  period  not exceeding 20 consecutive quarterly
payments  (five  years),  provided there is no event of default and the deferral
does  not  extend  beyond  June  15,  2036.
