                                EXPLANATORY NOTE

         In November  2004, the  Securities  and Exchange  Commission  issued an
exemptive  order  providing  companies with a market  capitalization  under $700
million with an extension of up to 45 days for the filing of management's report
on the company's  internal  controls over  financial  reporting and the required
attestation  on  those   controls  from  the   independent   registered   public
accountants.  Berkshire Hills Bancorp, Inc. (the "Company") elected to utilize a
portion of this  extension  period.  Therefore,  the Company  hereby  amends its
Annual Report on Form 10-K,  filed March 15, 2005 (the  "Original  Filing"),  to
include Management's Report on Internal Control Over Financial Reporting and the
Report of Independent  Registered  Public  Accounting  Firm required in Item 9A,
"Controls and Procedures" on Form 10-K.

                                    PART III

ITEM 9A. CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

         The Company's  management,  including the Company's principal executive
officer and principal financial officer, have evaluated the effectiveness of the
Company's  "disclosure controls and procedures," as such term is defined in Rule
13a-15(e)  promulgated  under the  Securities  Exchange Act of 1934, as amended,
(the  "Exchange  Act").  Based upon their  evaluation,  the principal  executive
officer and principal  financial  officer  concluded  that, as of the end of the
period covered by this report, the Company's  disclosure controls and procedures
were effective for the purpose of ensuring that the  information  required to be
disclosed  in the reports that the Company  files or submits  under the Exchange
Act with the  Securities  and Exchange  Commission  (the "SEC") (1) is recorded,
processed,  summarized  and reported  within the time  periods  specified in the
SEC's rules and forms,  and (2) is accumulated and communicated to the Company's
management,  including its principal executive and principal financial officers,
as appropriate to allow timely decisions regarding required disclosure.

CHANGES IN INTERAL CONTROL OVER FINANCIAL REPORTING

         No change in the Company's  internal  control over financial  reporting
occurred  during  the  quarter  ended  December  31,  2004  that has  materially
affected, or is reasonably likely to affect, the Company's internal control over
financial reporting.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

         The  management  of the Company is  responsible  for  establishing  and
maintaining  adequate  internal control over financial  reporting.  The internal
control  process has been designed under our  supervision to provide  reasonable
assurance  regarding the reliability of financial  reporting and the preparation
of the  Company's  financial  statements  for  external  reporting  purposes  in
accordance with accounting principles generally accepted in the United States of
America.

         Management   conducted  an  assessment  of  the  effectiveness  of  the
Company's  internal  control over  financial  reporting as of December 31, 2004,
utilizing the framework established in "INTERNAL CONTROL - INTEGRATED FRAMEWORK"
issued by the Committee of Sponsoring  Organizations of the Treadway Commission.
Based on this assessment,  management has determined that the Company's internal
control over financial reporting as of December 31, 2004 is effective.

         Our internal  control over financial  reporting  includes  policies and
procedures that pertain to the maintenance of records that accurately and fairly
reflect,  in reasonable  detail,  transactions and  dispositions of assets;  and
provide  reasonable  assurances that: (1) transactions are recorded as necessary
to permit  preparation  of financial  statements in accordance  with  accounting
principles   generally   accepted  in  the  United  States;   (2)  receipts  and
expenditures are being made only in accordance with authorizations of management
and the directors of the Company; and (3) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition,  use, or disposition
of the  Company's  assets  that could have a  material  effect on the  Company's
financial statements.

         All  internal  control  systems,  no  matter  how well  designed,  have
inherent limitations.  Therefore,  even those systems determined to be effective
can provide only reasonable assurance with respect to financial statement

preparation   and   presentation.   Also,   projections  of  any  evaluation  of
effectiveness to future periods are subject to the risk that controls may become
inadequate  because of changes in  conditions,  or that the degree of compliance
with the policies or procedures may deteriorate.

         Management's  assessment of the effectiveness of the Company's internal
control  over  financial  reporting  as of December 31, 2004 has been audited by
Wolf & Company,  P.C., an  independent  registered  public  accounting  firm, as
stated in their report,  which  follows.  This report  expresses an  unqualified
opinion on  management's  assessment and on the  effectiveness  of the Company's
internal control over financial reporting as of December 31, 2004.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders
Berkshire Hills Bancorp, Inc.

We have audited management's assessment,  included in Management's Annual Report
on Internal Control Over Financial Reporting, that Berkshire Hills Bancorp, Inc.
maintained  effective  internal control over financial  reporting as of December
31,  2004,  based  on  criteria  established  in  INTERNAL   CONTROL--INTEGRATED
FRAMEWORK  ISSUED BY THE COMMITTEE OF SPONSORING  ORGANIZATIONS  OF THE TREADWAY
COMMISSION (COSO).  Berkshire Hills Bancorp Inc.'s management is responsible for
maintaining  effective  internal  control over  financial  reporting and for its
assessment of the  effectiveness of internal  control over financial  reporting.
Our  responsibility  is to express an opinion on management's  assessment and an
opinion on the  effectiveness  of the company's  internal control over financial
reporting based on our audit.

We conducted  our audit 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  effective
internal  control  over  financial  reporting  was  maintained  in all  material
respects. Our audit included obtaining an understanding of internal control over
financial reporting,  evaluating management's assessment, testing and evaluating
the design and operating  effectiveness of internal control, and performing such
other  procedures as we considered  necessary in the  circumstances.  We believe
that our audit provides a reasonable basis for our opinion.

A company's  internal control over financial  reporting is a process designed to
provide reasonable  assurance  regarding the reliability of financial  reporting
and the preparation of financial  statements for external purposes in accordance
with generally accepted accounting principles. A company's internal control over
financial  reporting  includes those policies and procedures that (1) pertain to
the  maintenance  of records that, in reasonable  detail,  accurately and fairly
reflect the  transactions  and  dispositions  of the assets of the company;  (2)
provide  reasonable  assurance  that  transactions  are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted
accounting  principles,  and that receipts and  expenditures  of the company are
being made only in accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding prevention or timely
detection of  unauthorized  acquisition,  use, or  disposition  of the company's
assets that could have a material effect on the financial statements.

Because of its inherent  limitations,  internal control over financial reporting
may not prevent or detect misstatements.  Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become
inadequate  because of changes in  conditions,  or that the degree of compliance
with the policies or procedures may deteriorate.

In our opinion,  management's  assessment  that Berkshire  Hills  Bancorp,  Inc.
maintained  effective  internal control over financial  reporting as of December
31,  2004,  is  fairly  stated,  in all  material  respects,  based on  criteria
established in INTERNAL CONTROL--INTEGRATED FRAMEWORK ISSUED BY THE COMMITTEE OF
SPONSORING ORGANIZATIONS OF THE TREADWAY COMMISSION (COSO). Also in our opinion,
Berkshire Hills Bancorp,  Inc. maintained,  in all material respects,  effective
internal  control over  financial  reporting  as of December 31, 2004,  based on
criteria  established in INTERNAL  CONTROL--INTEGRATED  FRAMEWORK  ISSUED BY THE
COMMITTEE OF SPONSORING ORGANIZATIONS OF THE TREADWAY COMMISSION (COSO).

We have also  audited,  in accordance  with the standards of the Public  Company
Accounting   Oversight  Board  (United  States),   the  consolidated   financial
statements of Berkshire  Hills Bancorp,  Inc. and our report dated March 9, 2005
expressed an unqualified opinion.
