Item 1.01   Entry into a Material Definitive Agreement.

     On November 13, 2007,  Oritani  Financial Corp. (the "Oritani") the holding
company for Oritani  Savings Bank,  entered into an Agreement and Plan of Merger
with Greater Community Bancorp  ("Greater  Community"),  the holding company for
Greater Community Bank. As part of the transaction,  Greater Community Bank will
be merged into Oritani  Savings Bank.  The combined  institution  will have $2.3
billion in assets and 36 branches  serving  Bergen,  Passaic,  Hudson and Morris
Counties, New Jersey. Under the terms of the Merger Agreement, Greater Community
shareholders  will be entitled to receive  $21.40 per share in Oritani  stock or
cash, provided that in the aggregate the consideration will be 60% stock and 40%
cash. The exchange ratio for the stock  consideration  will equal $21.40 divided
by the Oritani  market value as defined in the Merger  Agreement,  provided that
the  exchange  ratio  shall not be more than  1.4588  or less than  1.1935.  The
transaction  is subject  to the  approval  of the  shareholders  of Oritani  and
Greater Community, the receipt of regulatory approvals and other customary terms
and conditions. It is expected to close in the second calendar quarter of 2008.

forward-looking   statements  within  the  meaning  of  the  Private  Securities
Litigation Reform Act of 1995. As such, the statements involve significant risks

within  expected  time  frames;  (2) revenues  following  the merger not meeting
expectations;  (3) failure to retain the customer bases of the two  institutions
following the merger;  (4) competitive  pressures  among financial  institutions
increasing  significantly;  (5) costs or difficulties related to the integration
of  the  businesses  of  Greater   Community  and  Oritani  being  greater  than
anticipated;   (6)  general  economic   conditions  being  less  favorable  than
anticipated;  (7)  legislation  or regulatory  changes  adversely  affecting the
business in which the combined  company  will be engaged;  and (8) the timing of
the completion of the transactions.
