ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

     On November 29, 2007, the Registrant and Columbia Financial Corporation
entered into an Agreement and Plan of Reorganization (the "Merger Agreement")
whereby Columbia Financial Corporation will be merged with and into the
Registrant. The surviving corporation to the Merger Agreement will be the
Registrant. Simultaneously or as soon as practicable after the effective time as
that term is defined in the Merger Agreement, the Registrant's wholly-owned
subsidiary, Columbia County Farmers National Bank, will be merged with and into
Columbia Financial Corporation's wholly-owned subsidiary, First Columbia Bank &
Trust Co. (the "Bank Merger"). The surviving institution to the Bank Merger
shall be First Columbia Bank & Trust Co.

     Pursuant to the terms of the Merger Agreement, the stockholders of Columbia
Financial Corporation will receive 0.7200 shares of the common stock, par value
$1.25 per share, of the Registrant for each share of the common stock of
Columbia Financial Corporation held by them.

     The transaction is subject to stockholder approval by the stockholders of
the Registrant and Columbia Financial Corporation, customary regulatory
approvals and other conditions provided for in the Merger Agreement. Prior to
the stockholders' meetings, the Registrant will file a registration statement
with the Securities and Exchange Commission to register the shares to be issued
in connection with the Merger Agreement. The transaction is expected to close in
the third quarter of 2008.

     A copy of the Merger Agreement is attached hereto as Exhibit 2.1 and
incorporated herein by reference. Furthermore, a copy of the press release
relating to the Merger Agreement is attached hereto as Exhibit 99.1 and
