The foundation will be dedicated to charitable  causes within the communities in

Unfortunately,  William Penn Bancorp, Inc. is unable to either offer or sell its
common stock to you because of the small number of eligible  subscribers in your
jurisdiction  makes  registration or qualification of the common stock under the
securities  laws  of  your  jurisdiction  impractical  for  reasons  of  cost or
otherwise.  Accordingly, this letter and the enclosures should not be considered
an  offer to sell or a  solicitation  of an  offer  to buy the  common  stock of
William Penn Bancorp, Inc.

However as a member of William Penn Bank, you have the right to vote on the Plan
of  Reorganization  and Stock  Issuance  at the  Special  Meeting of the Special
Meeting  of  Members  to be  held on  ____________,  2008.  Enclosed  is a proxy

What Investors Need to Know

         Key concepts for investors to bear in mind when considering  whether to
participate in a conversion  offering,  or a stock offering by a subsidiary of a
mutual holding company, include the following:

     o   Know the Rules By law,  accountholders  cannot sell or  transfer  their
         priority  subscription  rights,  or  the  stock  itself,  prior  to the
         completion   of  a  financial   institution's   conversion.   Moreover,
         accountholders  cannot enter into agreements or arrangements to sell or
         transfer either their subscription rights or the underlying  conversion
         stock.

     o   "Neither  a Borrower  nor a Lender  Be" If  someone  offers to lend you
         money  so that  you can  participate  or  participate  more  fully in a
         conversion,  be extremely  wary. Be even more wary if the source of the
         money is  someone  you do not  know.  The loan  agreement  may make you
         unable  to  certify  truthfully  that  you are the true  holder  of the
         subscription  rights and the true  purchaser  of the stock and that you
         have no agreements regarding the sale or transfer of the stock.

     o   Watch Out for  Opportunists The opportunist may tell you that he or she
         is a  lawyer  or  a  consultant  or a  professional  investor  or  some
         similarly  impressive  tale  who has  experience  with  similar  mutual
         conversion  transactions.  The opportunist may go to extreme lengths to
         assure you that the  arrangement  you are entering into is  legitimate.
         They  might tell you that they have done  scores of these  transactions
         and that this is simply  how they  work.  Or they  might  downplay  the
         warnings or restrictions  in the prospectus or order form,  telling you
         that  "everyone"  enters into such agreements or that the deal they are
         offering is legitimate. They may also tell you that you have no risk in
         the  transaction.  The cold,  hard truth is that these are lies, and if
         you participate, you are breaking the law.

     o   Get the  Facts  from the  Source  If you have any  questions  about the
         securities  offering,  ask the savings bank or savings  association for
         more information.  If you have any doubts about a transaction  proposed
         to you by someone  else,  ask the  financial  institution  whether  the
         proposed  arrangement  is  proper.  You may be  able  to  find  helpful
         resources on the institution's website or by visiting a branch office.

         The  bottom  line  for  investors  is  always  to  remember  that if an
         opportunity  sounds too  good to be true, it probably is too good to be
         true.




                                 Read This First

            Office of Thrift Supervision Guidance for Accountholders


         Your  financial  institution  is in the process of selling stock to the
public,  in  either  a  mutual-to-stock  conversion  or a  stock  issuance  by a
subsidiary of a mutual holding company. As an accountholder at this institution,
you have certain priority subscription rights to purchase stock in the offering.
These priority  subscription rights are  non-transferable.  If you subscribe for
stock,  you will be asked to sign a statement  that the purchase is for your own
account,  and  that  you  have  no  agreement  or  understanding  regarding  the
subsequent sale or transfer of any shares you receive.

         On occasion,  unscrupulous people attempt to persuade accountholders to
transfer subscription rights, or to purchase shares in the offering based on the
understanding  that the shares will subsequently be transferred to others.  Such
arrangements violate federal  regulations.  If you participate in these schemes,
you are breaking the law and may be subject to prosecution.  If someone attempts
to persuade you to participate in such a scheme, please contact Office of Thrift
Supervision (OTS) at (202) 906-6202. OTS is very interested in ensuring that the
prohibitions on transfer of subscription rights are not violated.

         How will you know if you are being approached illegally?  Typically,  a
fraudulent  opportunist  will  approach  you and  offer to  "loan"  you money to
purchase a  significant  amount of stock in the  offering.  In exchange for that
"loan" you most  likely will be asked  either to  transfer  control of any stock
purchased with that money to an account the other person  controls,  or sell the
stock and give the majority of the profits to the other person. You may be told,
untruthfully,  that there is no risk to you,  that the  practice is common,  and
even if you are caught, that your legal expenses will be covered.

         On the back of this page is a list of some key concepts that you should
keep in mind  when  considering  whether  to  participate  in a  mutual-to-stock
conversion or stock issuance by a mutual holding company subsidiary. If you have
questions,  please contact the stock information  center listed elsewhere in the
literature   you  are   receiving.   Alternatively,   you  can  contact  us  at:

As a Mutual Institution:

- -    Our earnings from year to year are the only source of generating capital.

Under a Mutual Holding Company structure, we will be able to:
- -------------------------------------------------------------
- -    Structure  our  business in the form that will enable us to access  capital
     markets.
- -    Support future lending and operational growth.
- -    Better  attract  and retain  qualified  directors  and  management  through
     stock-based compensation plans.
- -    Support  future  branching  activities  and/or  the  acquisition  of  other
     financial institutions or financial services companies.

                         FACTS ABOUT THE REORGANIZATION


The Board of Directors of William Penn Bank, FSB  unanimously  adopted a Plan of
Reorganization  and Stock Issuance to reorganize  into a mutual holding  company
structure.  As a result of the reorganization,  William Penn Bancorp,  Inc. will
become the federally  chartered parent holding company of William Penn Bank, FSB
("William  Penn"),  and William Penn Bancorp,  Inc. will be 70% owned by William
Penn MHC. In connection with the reorganization,  William Penn Bancorp,  Inc. is
offering a minority of its common stock in a subscription offering to the public
pursuant to a Plan of Reorganization  and Stock Issuance.  William Penn MHC will
be the majority  stockholder  of the common stock of William Penn Bancorp,  Inc.
after  the  reorganization.  William  Penn  MHC  will  have as its  members  the
depositor and borrower members of William Penn.

This brochure  answers some of the most  frequently  asked  questions  about the
reorganization  and about your  opportunity  to invest in William Penn  Bancorp,
Inc.

Investment in the stock of William Penn Bancorp,  Inc.  involves  certain risks.
For a  discussion  of these  risks  and  other  factors,  including  a  complete
description  of the  offering,  investors  are  urged to read  the  accompanying
Prospectus, especially the discussion under the heading "Risk Factors."

WHAT IS THE PURPOSE OF THE REORGANIZATION?
- --------------------------------------------------------------------------------
The  primary  reasons  for the  reorganization  and our  decision to conduct the
offering are to:

- - Increase our capital  allowing us to seek to implement a growth strategy while
maintaining a solid capital position;

- - Provide us with greater  operating  flexibility and allow us to better compete
with other financial institutions; and

- - Retain  the  characteristics  of a mutual  organization.  The  mutual  holding
company structure will allow our mutual holding company to retain voting control
over most decisions to be made by William Penn shareholders.

WILL THE REORGANIZATION AFFECT ANY OF MY DEPOSIT ACCOUNTS OR LOANS?
- --------------------------------------------------------------------------------
No.  The  reorganization  will not affect  the  balance or terms of any  deposit
account or loan.  Your  deposits  will  continue to be federally  insured by the
Federal Deposit Insurance  Corporation ("FDIC") to the maximum legal limit. Your
deposit account is not being converted to stock.

DO DEPOSITORS HAVE TO BUY STOCK?
- --------------------------------------------------------------------------------
No.  However,  the  reorganization  will  allow  William  Penn's  depositors  an
opportunity to buy stock and become stockholders of William Penn Bancorp, Inc.

1,851,500  shares  as a  result  of  regulatory  considerations  or  changes  in
financial markets.

HOW MUCH STOCK MAY I BUY?

CAN I PURCHASE SHARES USING FUNDS IN MY WILLIAM PENN IRA?

brokerage firm or trust department to which you can transfer a portion or all of
your IRA account at William Penn that will enable such purchase.  Please contact
your  broker or  self-directed  IRA  provider as soon as possible if you want to

MAY I OBTAIN A LOAN FROM WILLIAM PENN TO PAY FOR THE STOCK?
- --------------------------------------------------------------------------------
No.  Regulations  do not allow William Penn to make loans for this purpose,  nor
may you use a William  Penn line of credit to pay for shares.  However,  you are
not precluded from obtaining financing from another financial institution.

DOES PLACING AN ORDER  GUARANTEE  THAT I WILL RECEIVE ALL, OR A PORTION,  OF THE
SHARES I ORDERED?
- --------------------------------------------------------------------------------
No. It is possible that orders  received  during the stock  offering will exceed
the  number  of  shares  offered  for  sale.  In this  case,  referred  to as an
"oversubscription,"   regulations   require   that  orders  be  filled  using  a
pre-determined  allocation  procedure.  Please  refer  to  the



section of the Prospectus titled,  "The Reorganization and Stock Offering" for a
detailed description of allocation procedures.

If we are not able to fill an order  (either  wholly or in part),  excess  funds
will be refunded by check,  including  interest earned at William Penn's regular
passbook  savings rate.  If payment is to be made by  withdrawal  from a William
Penn deposit account, excess funds will remain in that account.

WILL THE STOCK BE INSURED?
- --------------------------------------------------------------------------------
No. Like any other common stock, William Penn Bancorp,  Inc.'s stock will not be
insured.

WILL DIVIDENDS BE PAID ON THE STOCK?
- --------------------------------------------------------------------------------

not yet made plans as to the  amount or timing of cash  dividends  that  William
Penn Bancorp may pay after the  offering.  The timing,  amount and  frequency of
dividends will be determined by the Board of Directors.

I further  certify  that,  before  purchasing  the common  stock of William Penn
Bancorp,  Inc.,  I  received a copy of the  Prospectus  dated  _________,  which
discloses  the  nature of the common  stock  being  offered  and  describes  the
following  risks involved in an investment in the common stock under the heading
"Risk Factors" beginning on page 11 of the prospectus:

- -    We realize income primarily from the difference  between interest earned on
     loans and  investments  and interest paid on deposits and  borrowings;  and
     changes in interest rates may adversely affect us.

- -    At  September  30,  2007,  approximately  28% of our total  loan  portfolio
     consisted of multi-family and nonresidential mortgage loans, land loans and
     construction  loans.  The repayment risk related to these types of loans is
     considered  to be  greater  than the  risk  related  to one to four  family
     residential loans. Part of our business plan is to increase our origination
     of multi-family and nonresidential mortgage loans.

- -    A significant amount of our one to four family residential lending consists
     of "investor  loans" (defined as loans on non-owner  occupied  properties),
     and this may expose us to increased lending risks.

- -    The market for stock of financial  institutions has been unusually volatile
     recently, and our stock price may decline when trading commences.

- -    If we do not achieve  profitability  on new branches,  the new branches may
     hurt our earnings.

- -    The loss of senior management could hurt our operations.

- -    Strong competition within our industry and market area may limit our growth
     and profitability.

- -    Our business is  geographically  concentrated  in and around Bucks  County,
     Pennsylvania,  and a downturn  in economic  conditions  in this market area
     could have an adverse impact on our profitability.

- -    There is a potential for loss on a sizable land loan in our portfolio  that
     is in default.

- -    If we experience loan losses in excess of our allowance,  our earnings will
     be adversely affected.

- -    Our  return  on  equity  is  currently  low and will  decrease  after  this
     offering. This could negatively impact the price of our stock.

- -    Additional  compensation and benefit  expenses  following the offering will
     negatively impact our profitability.

- -    New  expenses  that we will  incur  as a public  company  will  affect  our
