                     American Bank of New Jersey 2005 Restricted Stock Plan

Gentlemen:

         We have acted as special  counsel to  American  Bancorp of New  Jersey,
Inc.,  a  New  Jersey  corporation  (the  "Company"),  in  connection  with  the
preparation  of the  Registration  Statement  on Form S-8 to be  filed  with the
Securities and Exchange  Commission  (the  "Registration  Statement")  under the
Securities Act of 1933, as amended,  relating to 902,607 shares of common stock,
par value $.10 per share (the "Common Stock") of the Company which may be issued
(i) upon the  exercise  of options for 694,314  shares of Common  Stock  granted
under the American Bancorp of New Jersey,  Inc. 2005 Stock Option Plan, and (ii)
upon the award of 208,293  shares of Common Stock under the American Bank of New
Jersey 2005 Restricted  Stock Plan  (collectively,  the "Plans"),  as more fully
described in the Registration Statement.  You have requested the opinion of this
firm with respect to certain legal aspects of the proposed offering.

         We have examined such documents, records, and matters of law as we have
deemed  necessary for purposes of this opinion and based thereon,  we are of the
opinion that the Common Stock when issued  pursuant to the stock awards  granted
under and in  accordance  with the terms of the Plans  will be  validly  issued,
fully paid, and nonassessable.

         We hereby  consent to the  filing of this  opinion as an exhibit to the
Registration Statement on Form S-8.


                                                  Sincerely,
