This supplements the prospectus of Oritani Financial Corp. dated May 10, 2010, relating to the syndicated community offering. This prospectus supplement should be read together with the prospectus.
 
We have commenced a syndicated community offering to sell additional shares.
 
The number of shares available for sale in the syndicated community offering will be reduced by the number of shares sold in the subscription offering and community offering.
 
We are increasing the number of shares that you may purchase in the offering.
 
We have increased the amount of stock that you may purchase as follows:
 
  •  You may now purchase up to $1.5 million (150,000 shares) in the offering.
 
  •  You, together with any associates or persons who may be acting in concert with you (as defined in the prospectus), may now purchase up to $8.0 million (800,000 shares) in the offering.
 
The ownership limitations for current Oritani Financial Corp. stockholders disclosed in the prospectus remain unchanged.
 
These purchase limitations apply to purchases made in the subscription, community or syndicated community offerings. If you have purchased shares of common stock in the subscription, community and syndicated community offerings, your total orders must comply with the purchase limitations set forth above.
 
Completion of the offering remains subject to (1) approval of our plan of conversion and reorganization by Oritani Financial Corp.’s stockholders and Oritani Bank’s depositors, (2) receipt of final regulatory approvals, including approval of an updated appraisal, and (3) the sale of at least 33,150,000 shares of common stock, which is the minimum of our offering range.
