                -----------


         Effective January 27, 2010, SI Financial Group, Inc. (the "Registrant")
amended Article III, Section 2 of its Bylaws to decrease the size of its Board
of Directors from eight to seven members to eliminate the vacancy created by the
resignation of Steven H. Townsend in July 2009. A copy of the Article III,
Section 2, as amended, is attached hereto as an exhibit and incorporated herein
by reference.

         Before such amendment, Article III, Section 2 read as follows:

         "Section 2. Number and Term. The board of directors shall consist of
         eight members and shall be divided into three classes as nearly equal
         in number as possible. The members of each class shall be elected for a
         term of three years and until their successors are elected and
         qualified. One class shall be elected by ballot annually."

         The Bylaws of each of SI Bancorp, MHC, the Registrant's parent mutual
holding company, and Savings Institute Bank and Trust Company, the Registrant's
wholly-owned subsidiary, also were amended similarly effective January 27, 2010.
