Dear Fellow Shareholder of Prudential Bancorp, Inc. of Pennsylvania:


     It is the Stilwell Group's intention to hold its nine-percent plus position
indefinitely,  and to actively oppose, for at least the next decade, through the
solicitation  of  proxies or  otherwise,  the  proposed  stock  recognition  and
retention and stock option plans  (together,  the "Stock  Benefit  Plans") until
such time as a  representative  of the Group is appointed to the Company's Board
of Directors  and a  satisfactory  agreement on capital  allocation  is reached.
(Because FDIC regulations currently bar the Company's parent,  Prudential Mutual
Holding Company,  which holds 55.3 % of the Company's  outstanding common stock,
from voting on equity  compensation  plans such as the Stock Benefit Plans, only
the public shareholders are able to approve such plans.) The Group will not sell
its shares in a block trade or accept a payment from the Company. The Group will
only sell its shares  proportionally  as the share  count is reduced in order to
stay below 9.9% of the outstanding  shares. In other words, the Group intends to
be a  shareholder  for the long haul and has no  intention  of "going away" just
because the Company has put off its planned  adoption of the Stock Benefit Plans
to avoid a shareholder vote.

     I  believe  that the  Company's  directors,  who  have no prior  experience
sitting on the board of a public  company,  no prior  experience  in  allocating
capital for a public company and do not  personally own a substantial  number of
shares of the Company's  stock,  clearly need help in  allocating  the Company's
capital.  Since May 2005,  when the  Company  announced  its plan to  repurchase
277,000 shares of its stock, through December 16, 2005, IT ONLY PURCHASED 66,300
SHARES.  It purchased those shares in May and June but made no purchases for the
rest of the year, even though the shares  continued to trade at a price that the
Group believes to be attractive. In my estimation, there is simply no excuse for
the Company not to have already completed its May 2005 share repurchase program.
I can only conclude that the Company could use the Group's assistance.

     By withholding  your vote you can send a strong message to the Company that
you believe your  investment  is best served by having a  representative  of the
Group on the Board.



     WE URGE YOU TO WITHHOLD YOUR VOTE FROM THE ELECTION OF DIRECTORS,  WHICH IS
PROPOSAL 1 ON THE ENCLOSED  PROXY CARD,  BY MARKING THE BOX  "WITHHOLD."  IF YOU
RECEIVE A CARD FROM THE COMPANY, THROW IT IN THE GARBAGE.


                                       Sincerely,

                                       /s/ Joseph Stilwell
                                       Joseph Stilwell
