             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
             -------------------------------------------------------


To the Trustees of the ESSA Bank & Trust 401(k) Plan
Stroudsburg, Pennsylvania


We have audited the accompanying statements of net assets available for benefits
of the ESSA Bank & Trust 401(k) Plan as of December  31, 2008 and 2007,  and the
related  statement of changes in net assets  available for benefits for the year
ended December 31, 2008. These financial  statements are the  responsibility  of
the  Plan's  management.  Our  responsibility  is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance  with the standards of the Public  Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the net assets available for benefits of the ESSA Bank &
Trust  401(k)  Plan as of  December  31,  2008 and 2007,  and the changes in net
assets  available  for  benefits  for the  year  ended  December  31,  2008,  in
conformity with U.S. generally accepted accounting principles.

As discussed in Note 7 to the financial  statements,  effective January 1, 2008,
the Plan adopted Statement of Financial Accounting Standards No. 157, Fair Value
Measurements.

Our audit was made for the purpose of forming an opinion on the basic  financial
statements  taken as a whole.  The  supplemental  schedule  of  Assets  Held for
Investment  Purposes as of December  31, 2008,  is presented  for the purpose of
additional  analysis  and  is  not  a  required  part  of  the  basic  financial
statements,  but is  supplementary  information  required  by the United  States
Department of Labor's Rules and Regulations  for Reporting and Disclosure  under
the Employee  Retirement Income Security Act of 1974. The supplemental  schedule
is the responsibility of Plan's management.  The supplemental  schedule has been
subjected  to the  auditing  procedures  applied  in  the  audits  of the  basic
financial  statements  and, in our  opinion,  is fairly  stated in all  material
respects in relation to the basic financial statements taken as a whole.

                          ESSA BANK & TRUST 401(k) PLAN
                          NOTES TO FINANCIAL STATEMENTS


NOTE 1 - DESCRIPTION OF PLAN

     The following  brief  description of the ESSA Bank & Trust 401(k) Plan (the
     "Plan") for  employees  of ESSA Bank & Trust (the  "Bank") is provided  for
     general  information  purposes only.  Participants should refer to the Plan
     Document for a more comprehensive description of the Plan's provisions.

     General
     -------

     The Plan is a defined  contribution plan covering the employees of the Bank
     who have attained the age of 21 and have  completed one year of service and
     1,000 hours of service. An employee becomes a participant on either January
     1 or July 1, depending on when  eligibility  requirements are met. The Plan
     includes a 401(k) before-tax savings feature, which permits participants to
     defer compensation under Section 401(k) of the Internal Revenue Code. It is
     subject to the provisions of the Employee Retirement Income Security Act of
     1974 (ERISA), as amended.

     Contributions
     -------------

     Employees may elect to contribute  any amount up to the maximum  percentage
     allowable,  not to exceed the limits of Code Sections 401(k),  402(g), 404,
     and 415.  The Bank  will  match 100  percent  of the  participant's  annual
     elective  deferrals  that do not  exceed  3  percent  of the  participant's
     compensation,  plus 50 percent of the  amount of the  participant's  annual
     elective  deferrals  that do not  exceed  5  percent  of the  participant's
     compensation.  The  participants  may direct  their  accounts  into several
     different   investment  options.   Contributions  are  subject  to  certain
     limitations.

     Participant Accounts
     --------------------

     Each participant's account is credited with Plan earnings.  Allocations are
     based upon participants' account balances at the beginning of the valuation
     period, while forfeitures related to the non-vested portion of the employer
     contributions  are reallocated to remaining  participants'  accounts in the
     ratio of each participant's compensation in relation to compensation of all
     participants. The benefit to which a participant is entitled is the benefit
     that can be provided from the participant's account.

     Vesting
     -------

     Participants are immediately  vested in their voluntary  contributions plus
     actual earnings thereon. Vesting in the sponsor's contributions in the Plan
     made prior to December 1, 2004, is based on completion of credited  service
     years. A credited  service year is considered one in which the  participant
     completed at least 1,000 hours of service.  Such  contributions are subject
     to a six-year graded vesting  schedule  pursuant to which such amounts vest
     in 20 percent  increments  after each completed year of service,  beginning
     after the completion of the second year of service.  Employer contributions
     made subsequent to December 1, 2004, are immediately vested.


                                       4





NOTE 1 - DESCRIPTION OF PLAN (Continued)

     Payment of Benefits
     -------------------

     Upon  termination  of service,  participants  whose  accounts do not exceed
     $1,000 may receive a lump-sum  amount equal to the value of their  account.
     Participants  whose  accounts  are  between  $1,000 and $5,000 may have the
     balance of their account rolled over into an IRA. Participants whose vested
     account  balance at the time of  termination  exceeds  $5,000 may receive a
     lump-sum distribution or an annuity or may defer payments of benefits until
     April 1 of the calendar  year  following the calendar year during which the
     participant reaches age 70 1/2.

     Forfeitures
     -----------

     At December 31, 2008 and December 31, 2007,  forfeited  nonvested  accounts
     totaled $4,  respectively.  These amounts will be utilized to reduce future
     employer contributions or to pay Plan administrative  expenses.  During the
     year ended  December 31, 2008 and 2007, $0 and $1,027 in  forfeitures  were
     utilized to reduce the employer's contribution.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accounting  principles followed by the Plan and the methods of applying
     these principles conform to U.S. generally accepted accounting principles.

     A summary of the significant  accounting and reporting  policies applied in
     the presentation of the accompanying financial statements follows:

     Accounting Estimates
     --------------------

     The  financial  statements  have  been  prepared  in  conformity  with U.S.
     generally  accepted  accounting  principles.  In  preparing  the  financial
     statements,  management is required to make estimates and assumptions  that
     affect the reported  amounts and  disclosures.  Actual results could differ
     significantly from those estimates.

     Valuation of Investments and Income Recognition
     -----------------------------------------------

     The Plan's  investments are stated at fair value.  The fair value of mutual
     funds is determined using the quoted net asset value of the specified fund.
     The fair value of ESSA Bancorp,  Inc. common stock is determined based on a
     quoted market price.

     The net appreciation  (depreciation) in fair value of investments  includes
     investments purchased, sold, and held during the year.

     Purchases  and sale of  investments  are  recorded on a  trade-date  basis.
     Interest income is recorded on the accrual basis. Dividends are recorded on
     the ex-dividend date.

     Payment of Benefits
     -------------------

     Benefit payments to participants are recorded upon distribution.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

     Administrative Expenses
     -----------------------

     Administrative  expenses of the Plan relating to investment  management and
     recordkeeping  fees are paid by the Plan.  Fees relating to accounting  and
     miscellaneous  administrative expenses are paid by the Plan's sponsor. Such
     expenses amounted to $14,895 for the year ended December 31, 2008.

NOTE 3 - INVESTMENTS

     The  Plan  investments  are  administered  by  Massachusetts   Mutual  Life
     Insurance Company ("trustee").

     Although it has not  expressed  any intent to do so, the Bank has the right
     under  the  Plan  to  discontinue  its  contributions  at any  time  and to
     terminate  the Plan  subject to the  provisions  of ERISA.  In the event of
     termination  of the Plan,  participants  will become 100 percent  vested in
     their accounts.

NOTE 5 - TAX STATUS

     The Plan  obtained its latest  determination  letter on April 23, 2002,  in
     which the Internal  Revenue Service stated that the Plan, as then designed,
     was in compliance with the applicable  requirements of the Internal Revenue
     Code. The Plan has been amended since receiving the  determination  letter.
     However,  the  Plan  administrator  believes  that  the  Plan is  currently
     designed and being operated in compliance with the applicable  requirements
     of the Internal Revenue Code.

NOTE 6 - PARTY-IN-INTEREST TRANSACTIONS

     Certain  Plan  investments  are shares of mutual  funds that are managed by
     Massachusetts  Mutual Life Insurance  Company,  the defined  trustee of the
     Plan.   Therefore,   related   transactions  qualify  as  party-in-interest
     transactions.  Fees  paid by the Plan for  investment  management  services
     amounted to $8,809 for the year ended December 31, 2008.

     At December 31, 2008,  the Plan held 332,049  shares of ESSA Bancorp,  Inc.
     common stock. Dividends received on these shares in 2008 totaled $37,244.

NOTE 7 - FAIR VALUE MEASUREMENTS

     Effective  January  1,  2008,  the  Plan  adopted  Statement  of  Financial
     Accounting  Standards  (FAS) No. 157, which,  among other things,  requires
     enhanced  disclosures  about assets and liabilities  carried at fair value.
     FAS No.  157  establishes  a  framework  for  measuring  fair  value.  That
     framework  provides a fair value  hierarchy that  prioritizes the inputs to
     valuation  techniques  used to measure fair value.  The hierarchy gives the
     highest  priority  to  unadjusted  quoted  prices  in  active  markets  for
     identical assets or liabilities and lowest priority to unobservable inputs.
     The  three  levels  of the  fair  value  hierarchy  under  FAS No.  157 are
     described below:

     Level I:       Inputs to the valuation  methodology  are unadjusted  quoted
                    prices for identical assets or liabilities in active markets
                    that the Plan has the ability to access.

     Level II:      Inputs to the valuation  methodology  include  quoted prices
                    for similar assets or liabilities in active markets;  quoted
                    prices for  identical or similar  assets or  liabilities  in
                    inactive  markets;  inputs other than quoted prices that are
                    observable  for the asset or liability;  and inputs that are
                    derived  principally  from  or  corroborated  by  observable
                    market data by correlation  or other means.  If the asset or
                    liability has a specified  (contractual)  term, the Level II
                    input must be observable for  substantially the full term of
                    the asset or liability.

     Level III:     Inputs to the valuation  methodology  are  unobservable  and
                    significant to the fair value measurement.

     The asset's or  liability's  fair value  measurement  level within the fair
     value  hierarchy  is  based  on the  lowest  level  of any  input  that  is
     significant to the fair value measurement.  Valuation  techniques used need
     to  maximize  the  use  of  observable  inputs  and  minimize  the  use  of
     unobservable inputs.

     Following is a description of the valuation  methodologies  used for assets
     measured  at fair  value.  There have been no changes in the  methodologies
     used at December 31, 2008 and 2007.

     Common Stocks
     -------------

     Valued at the  closing  price  reported  on the active  market on which the
     individual securities are traded.

     Mutual Funds
     ------------

     Valued  at the net  asset  value  ("NAV")  of  shares  held by the  Plan at
     year-end.

     The methods  described above may produce a fair value  calculation that may
     not be  indicative  of net  realizable  value or  reflective of future fair
     values.  Furthermore,  while the Plan  believes its  valuation  methods are
     appropriate  and  consistent  with other  market  participants,  the use of
     different  methodologies  or  assumptions  to  determine  the fair value of
     certain  financial  instruments  could  result in a  different  fair  value
     measurement at the reporting date.

NOTE 8 - FAIR VALUE OF FINANCIAL INSTRUMENTS

     Statement of Financial Accounting Standards No. 107, Disclosures About Fair
     Value of Financial Instruments, requires the Plan to disclose the estimated
     fair value of its financial instruments.  Financial instruments are defined
     as cash,  evidence of ownership  interest in an entity, or a contract which
     creates  an  obligation  or right to  receive  or  deliver  cash or another
     financial  instrument  from/to a second entity on potentially  favorable or
     unfavorable terms. Fair value is defined as the amount at which a financial
     instrument  could be exchanged  in a current  transaction  between  willing
     parties  other than in a forced  liquidation  or sale.  If a quoted  market
     price is available for a financial  instrument,  the  estimated  fair value
     would be  calculated  based upon the market  price per trading  unit of the
     instrument.

     Investments  in mutual  funds,  common stock and  contributions  receivable
     would be  considered  a  financial  instrument.  At  December  31, 2008 and
     December 31,  2007,  the carrying  amounts of these  financial  instruments
     approximate fair value.

NOTE 9 - RISKS AND UNCERTAINTIES

     The Plan invests in various investment  securities.  Investment  securities
     are exposed to various  risks such as  interest  rate,  market,  and credit
     risks.  Due to  the  level  of  risk  associated  with  certain  investment
     securities,  it is at least reasonably  possible that changes in the values
     of investment  securities will occur in the near term and that such changes
     could  materially  affect  participants'  account  balances and the amounts
     reported in the Statement of Net Assets Available for Benefits.
