                                  INTRODUCTION


This Proxy Statement is furnished to shareholders in connection with the
solicitation of proxies on behalf of the Board of Directors of Westbank
Corporation (the "Corporation") to be used at the 2005 Annual Meeting of
Shareholders of the Corporation (the "Annual Meeting") to be held at the
Storrowton Tavern, 1305 Memorial Avenue, West Springfield, Massachusetts, on
Wednesday, April 20, 2005 at 9:00 AM and at any adjournments thereof.

The close of business on February 28, 2005 has been fixed as the record date for
determination of shareholders of the Corporation entitled to notice of and to
vote at the Annual Meeting. The only class of issued and outstanding voting
securities of the Corporation is the $2.00 par value Common Stock (the "Common
Stock"). As of the record date, the number of shares of Common Stock outstanding
and entitled to vote at the Annual Meeting is 4,734,674. Each share of Common
Stock is entitled to one vote.

The affirmative vote of a plurality of the shares of Common Stock of the
Corporation represented at the Annual Meeting is required to elect Directors.

Execution of the enclosed proxy will not affect a shareholder's right to attend
the Annual Meeting and vote in person. A shareholder that has given a proxy has
the power to revoke it at any time before it is exercised by delivering notice
of revocation, or a duly executed proxy bearing a later date, to the Treasurer
of the Corporation.

ELECTION OF DIRECTORS

The Bylaws of the Corporation provide that the Board of Directors shall be
divided into three (3) classes as nearly equal in number as possible and that
the term of office of one class shall expire and a successor class shall be
elected at each Annual Meeting of the Shareholders. The Corporation's Board of
Directors presently consists of nine (9) members.

Five (5) Directors will continue to serve after the 2005 Annual Meeting of
Shareholders. In accordance with the Bylaws of the Corporation, the
Corporation's Board of Directors has nominated three (3) persons for election as
Directors at the Annual Meeting. If elected, they will serve a three (3)-year
term, until the 2008 Annual Meeting of Shareholders, or for such further time as
may be required for the election and qualification of their successors.

Unless returned proxies properly indicate that authority to vote for any of the
nominees named herein is withheld, all proxies received by the Corporation in
time for the 2005 Annual Meeting of Shareholders will be voted in favor of the
election of the nominees listed below. In the event any of the nominees named
herein becomes unable or unwilling to accept nomination for election, the
persons identified as proxies in the accompanying form of proxy will vote the
shares represented by executed proxies in favor of the nomination and election
of such substitute nominees as the Board of Directors of the Corporation may
select.

Corporation, with a class of securities registered pursuant to Section 12 of the

All members of the Board of Directors, with the exception of Mr. Chase, are
"independent" as that term is defined by the applicable listing standards of the
Nasdaq Stock Market as set forth in the National Association of Securities
Dealers (the "NASD Manual"), as those standards have been modified or amended.
Mr. Chase is considered an inside Director due to his employment as an executive
officer of the Corporation.


COMMITTEES

The Board of Directors each year appoints Directors to serve on standing
committees of the Board of Directors, including the Executive Committee, the
Compensation Committee, the Nominating Committee and the Audit Committee. The
members of the Executive Committee, the Compensation Committee, the Nominating
Committee and the Audit Committee of the Corporation also make up these same
committees for Westbank (the "Bank"), the wholly owned subsidiary of the
Corporation. All Directors attended at least 75% of the meetings of committees
of which they were a member during the period each was a Director.

                                        7


NOMINATING COMMITTEE

The Nominating Committee of the Board of Directors consists of three (3)
Directors. Current members of the Nominating Committee are Messrs. Chamberland,

Committee meets the definition of an "independent director" as defined in the
NASD Manual, as such standard has been modified or amended. The Nominating
Committee met one (1) time during 2004.

The Nominating Committee identifies candidates for the Board of Directors and
recommends individuals to be presented for shareholder approval at the Annual
Meeting and to fill any vacancies on the Board. Prospective nominees are
evaluated by the Nominating Committee on the basis of a subjective review of the
background of each prospective nominee and the current needs of the Corporation.
Factors considered by the Committee include:

     o    the candidate's background, including, but not limited to, education
          and employment experience;

     o    the candidate's standards of integrity, work ethic and commitment;

     o    the candidate's ability to devote sufficient time and effort to the
          duties of a Director, including, but not limited to, the candidate's
          service on other boards of directors; and

     o    The candidate's specific skills and experience in light of the needs
          of the corporation and the Board of Directors, including, but not
          limited to, the need for specific expertise to serve on committees of
          the Board.

The Committee may also consider other factors it deems appropriate. The
Committee may determine to interview candidates, either in person or by
telephone. Upon completion of the evaluation process, the Committee recommends
candidates for election to the Board of Directors.

The policy of the Nominating Committee is to consider any Director candidate
recommended by the shareholders on the same basis that the Committee considers
candidates identified by the Committee. Such recommendations must be made in
writing to Clerk, Westbank Corporation, 225 Park Avenue, Post Office Box 149,
West Springfield, Massachusetts 01090-0149, with whatever supporting material
the shareholders deems appropriate. All requests must be received at the above

responsibilities fall into three (3) broad categories:

     o    First, the Audit Committee is charged with monitoring the preparation
          of quarterly and annual financial reports by the Corporation's
          management, including discussions with management and the
          Corporation's outside auditors about the annual financial statements
          and key accounting and reporting matters.

     o    Second, the Audit Committee is responsible for matters concerning the
          relationship between the Corporation and its outside auditors,
          including recommending their appointment or removal; reviewing the
          scope of their audit services and related fees, as well as any other
          services being provided to the Corporation; and determining whether
          the outside auditors are independent (based in part on the annual
          letter provided to the Corporation by the outside auditors pursuant to
          INDEPENDENCE STANDARDS BOARD STANDARD NO. 1).

     o    Third, the Audit Committee oversees management's implementation of an
          effective system of internal controls, including review of policies
          relating to legal and regulatory compliance, ethics and conflicts of
          interest; and review of the activities and recommendations of the
          Corporation's internal and external auditing programs.

The Audit Committee has implemented procedures to ensure that during the course
of each fiscal year it devotes the attention it deems necessary or appropriate
to each of the matters assigned to it under the Committee's charter. To carry
out its responsibilities, the Audit Committee met seven (7) times during Fiscal
Year 2004.

MATERIAL AND SHOULD NOT BE DEEMED FILED OR INCORPORATED BY REFERENCE INTO ANY
OTHER CORPORATION FILING UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES
EXCHANGE ACT OF 1934, EXCEPT TO THE EXTENT THE CORPORATION SPECIFICALLY
INCORPORATES THIS REPORT BY REFERENCE THEREIN.

The Audit Committee met with both management and the Corporation's outside
auditors to review and discuss all financial statements prior to their issuance
and to discuss significant accounting issues. Management advised the Committee
that all financial statements were prepared in accordance with generally
accepted accounting principles. The Committee's review included discussion with
the outside auditors of matters required to be discussed pursuant to STATEMENT
ON AUDITING STANDARDS NO. 61 (COMMUNICATION WITH AUDIT COMMITTEES).

The Committee has received the written disclosures and the letter form the
independent auditors made to the Committee as required by the INDEPENDENCE
STANDARDS BOARD STANDARD NO. 1 (INDEPENDENCE DISCUSSIONS WITH AUDIT COMMITTEES).

Finally, the Committee continued to monitor the scope and adequacy of the
Corporation's internal auditing program, including proposals for adequate
staffing and to strengthen internal procedures and controls where appropriate.

On the basis of these reviews and discussions, the Committee recommended to the
Board of Directors that the Board approve the inclusion of the Corporation's
audited financial statements in the Corporation's Annual Report on Form 10-K for
the fiscal year ended December 31, 2004, for filing with the Securities and
Exchange Commission.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities and Exchange Act of 1934, as amended (the
"Exchange Act"), requires the Corporation's Directors, executive officers and
holders of more than ten percent (10%) of the Corporation's Common Stock to file
with the Securities and Exchange Commission initial reports of ownership and
reports of changes in ownership of Common Stock and other equity securities of
the Corporation. Based solely on its review of such forms received by it, or
written representatives from certain reporting process, the Corporation believes
that, during the fiscal year ended December 31, 2004, all such persons complied
with all Section 16(a) filing requirements.


TRANSACTIONS INVOLVING OFFICERS AND DIRECTORS

From time to time, the Corporation, through the Bank, enters into banking
transactions, in the ordinary course of business, with certain of the executive
officers and Directors of the Corporation, their immediate families or entities
in which such persons may have a ten percent (10%) beneficial interest or for
which such persons may serve as executive officers. All loans made to such
persons are on substantially the same terms as comparable transactions and do
not involve more than the normal risk of collection. The aggregate amount of
such loans at December 31, 2004 was $10,817,000. As of the date of this Proxy
Statement, all of the loans described herein are performing loans in accordance
with their original terms.

                        EXECUTIVE MANAGEMENT COMPENSATION

Compensation decisions for executive officers of the Corporation are made by the
Compensation Committee and approved by the full Board of Directors. Mr. Chase,
who is a member of the Board of Directors, as well as an Executive Officer of
the Corporation, is not a member of the Compensation Committee and neither
participated in the discussion or nor voted upon his compensation package as a
member of the Board of Directors.


REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE MANAGEMENT COMPENSATION

Set forth below is the report of the Compensation Committee of the Corporation
regarding executive management compensation, as required by applicable rules of
the Securities and Exchange Commission.

The executive compensation program of the Corporation consists of four (4)
primary components: base salary, cash incentive compensation, stock options and
restricted stock awards, all of which are administered by the Compensation
Committee.

Decisions by the Compensation Committee relating to the compensation of the
Corporation's executive officers are approved by the full Board of Directors,
except as otherwise set forth herein. In determining the proper amount of
compensation for each executive officer, the Compensation Committee considers
various factors, including, inter alia:

     o  the performance of the Corporation;
     o  the individual's performance as an executive officer of the Corporation;
     o  the amount of compensation paid to similarly situated executive officers
        in similar sized  corporations; and
     o  the length of service with the Corporation.

During 2001, the Corporation engaged the firm of Kaeding, Ernst & Company to
review the Bank's retirement plans for executive officers, including the 1995
Westbank Executive Supplemental Retirement Plan. As a result of this review, the
Compensation Committee adopted the 2001 Supplemental Retirement Plan. The
purpose of the supplemental plan is to provide executives with retirement
benefits that are comparable to those provided to its other employees.
Supplemental retirement benefits are provided to all of the executive officers
and certain other participants under various non-qualified plans. The 2001
Supplemental Retirement Plan is designed to provide a retirement benefit at
normal retirement (Age 65) equal to seventy-five percent (75%) of the
participant's compensation at retirement, less fifty percent (50%) of the Social
Security benefit and the simple life annuity value of the participant's account
balances derived from employer-provided contributions under all qualified and
non-qualified defined contribution plans maintained by the Corporation.
Supplemental retirement benefits are provided to certain employees, including
each executive officer, whose benefits under the Westbank Money Purchase Plan
are limited in amount under federal tax laws and regulations.

During 2001, the Compensation Committee engaged Thomas Warren & Associates,
Inc., to assist in establishing levels and an incentive compensation plan for
the Corporation's senior executives pursuant to the Corporation's Incentive
Compensation Plan, which is used by the Compensation Committee as a guide in
determining executive officer compensation.

The Corporation also maintains the 1996 Incentive Stock Option Plan (the "1996
Plan"). The 1996 Plan was established to promote the growth and profitability of
the Corporation and provide key employees with an incentive to achieve corporate
goals.

At the Corporation's 2004 Annual Meeting, shareholders approved the adoption of
the Westbank Corporation 2004 Recognition and Retention Plan, which functions as
a long-term incentive plan.

During 2004, the Chief Executive Officer, Donald R. Chase, received a salary
increase of $32,017, an increase of seven percent (7%) of his base salary. The
increase was recommended by the

                                       15


Compensation Committee following its evaluation of Mr. Chase's performance as
Chief Executive Officer and the overall performance of the Corporation for 2004.

The Compensation Committee believes that the 2004 compensation of executive
officers was reasonable, given the Corporation's performance and utilizing the
criteria listed above.

     value of aggregate restricted stock awards as of December 31, 2004 was
     $555,840, $185,288, and $185,288 for Messrs. Chase, Briggs and Lilly,
     respectively. Accelerated vesting occurs in the case of death or disability
     and upon retirement or a change of control.

(2)  The items included for 2004 consist of the following: annual contribution
     on behalf of the Money Purchase Pension Plan amounting to $21,025 for each
     executive; annual allocation under the Corporation's supplemental pension
     plans of $277,950, $49,161 and $83,797 for the accounts of Messrs. Chase,
     Briggs and Lilly respectively; annual contribution on behalf of the
     Corporation's 401K plan of $7,999, $7,875 and $7,063 for Messrs. Chase,
     Briggs and Lilly respectively.

EMPLOYMENT AGREEMENT

The Corporation has entered into an employment agreement with Mr. Donald R.
Chase to secure his services as President and Chief Executive Officer. This
employment agreement has a term of three (3) years, beginning on December 17,
2003, and may be renewed annually after a review of the executive's performance.
This agreement provides for an initial minimum annual salary of $429,235,
discretionary cash bonuses and participation on generally applicable terms and
conditions in other compensation and fringe benefit plans. It also guarantees
customary corporate indemnification, and errors and omissions insurance
coverage, throughout the employment term and for so long as the executive is
subject to suit for claims deriving from service to the Corporation and the Bank
after termination. The Corporation and the Bank may terminate the executive's
employment, and the executive may resign, at any time with or without cause.
However, in the event of termination during the term without cause, the
executive will be owed severance benefits generally equal to the value of the
cash compensation and fringe benefits (including the value of accruals under
both tax-qualified and non-qualified benefit plans in which he participates)
that the executive would have received if he had continued working for the
remaining unexpired term of the agreement. The same severance benefits would be
payable if the executive resigns during the term following: a loss of title,
office or membership on the Board of Directors; material reduction in duties,
functions or responsibilities; or other material breach of contract by the
Corporation or the Bank that is not cured within thirty (30) days. For ninety
(90) days after a change in control, the executive may resign for any reason and
collect severance benefits as if he had been discharged without cause,
calculated as if the remaining unexpired term of the agreement were three (3)
years. If the Corporation or the Bank experiences a change in ownership, a
change in effective ownership or control, or a change in the ownership of a
substantial portion of their assets as contemplated by Section 280G of the
Internal Revenue Code, a portion of any severance payments under the employment
agreement might constitute an "excess parachute payment" under current federal
tax laws. Federal tax laws impose a twenty percent (20%) excise tax, payable by
the executive, on excess parachute payments. Under the employment agreement, the
Corporation would reimburse the executive for the amount of this excise tax and
would make an additional gross-up payment so that, after payment of the excise
tax and all income and excise taxes imposed on the reimbursement and gross-up
payments, the executive will retain approximately the same net-after-tax amounts
under the employment agreement that he would have retained if there were no
twenty percent (20%) excise tax. The effect of this provision is that the
Corporation, rather than the executive, bears the financial cost of the excise
tax. Neither the Corporation nor the Bank could claim a federal income tax
deduction for an excess parachute payment, excise tax reimbursement payment or
gross-up payment.


CHANGE OF CONTROL AGREEMENTS

The Corporation and the Bank have jointly entered into thirty (30)-month change
of control agreements with each of Messrs. Briggs and Lilly. The term of these
agreements is perpetual until the Bank gives notice of non-extension, at which
time the term is fixed for thirty (30) months. Generally, the Bank may terminate
the employment of any officer covered by these agreements, with or without
cause, at any time prior to a change of control without obligation for severance
benefits.

However, if the Bank or the Corporation signs a merger or other business
combination agreement, or if a third party makes a tender offer or initiates a
proxy contest, it could not terminate an officer's employment without cause
without liability for severance benefits. The severance benefits would generally
be equal to the value of the cash compensation and fringe benefits that the
officer would have received if he or she had continued working for an additional
thirty months. The Bank would pay the same severance benefits if the officer
resigns after a change of control. If the Bank or the Corporation experiences a
change in ownership, a change in effective ownership or control, or a change in
the ownership of a substantial portion of their assets as contemplated by
Section 280G of the Internal Revenue Code, a portion of any severance payments
under the change of control agreements might constitute an "excess parachute
payment" under current federal tax laws. Federal taw laws impose a 20% excise
tax, payable by the officer, on excess parachute payments. Under the change of
control agreement, the Corporation would reimburse the officers for the amount
of this excise tax and would make an additional gross-up payment so that, after
payment of the excise tax and all income and excise taxes imposed on the
reimbursement and gross-up payments, the officers would retain approximately the
same net-after-tax amounts under the

                                       17


change of control agreement that they would have retained if there were no
twenty percent (20%) excise tax. Neither the Corporation nor the Bank would
claim a federal income tax deduction for an excess parachute payment, excise tax
reimbursement payment or gross-up payment.


1985 INCENTIVE STOCK OPTION PLAN FOR KEY EMPLOYEES

In February 1985, the Board of Directors of the Corporation unanimously adopted
the 1985 Incentive Stock Option Plan for Key Employees (the "1985 Stock Plan"),
which was approved by the shareholders at the Annual Meeting in April 1985.

The 1985 Stock Plan is administered by the Board of Directors. The Board of
Directors was authorized to grant stock options to the professional and
supervisory employees of the Corporation and its subsidiaries at any time until
February 19, 1995.

All options were granted at 100% of the fair market value of the Common Stock of
the Corporation on the date of the grant. Each stock option terminates not more
than ten (10) years after the date of the grant. Options are exercisable in such
installments as may be determined by the Board of Directors. Payment of stock
purchased on the exercise of a stock option must be made in full at the time the
stock is exercised. Options may not be assigned or transferred, other than by
will or the laws of descent or distribution.

As of February 19, 1995, the 1985 Stock Plan expired. No options were granted or
available for granting during 2004.

A total of 4,796 options were exercised in 2004. No options were terminated
during 2004 and all options granted under the 1985 Stock Plan have been
exercised.

1996 STOCK INCENTIVE PLAN

On February 21, 1996, the Board of Directors unanimously adopted the Corporation
1996 Stock Incentive plan (the "1996 Plan"), which was approved by the
shareholders at the Annual Meeting in April 1996. The 1996 Plan was amended at
the 2002 Annual Meeting of Shareholders to increase by 200,000 the number of
shares reserved for issuance thereunder.

The 1996 Plan is administered by the Compensation Committee. The Committee is
authorized to grant Employee Awards under the 1996 Plan to any employee. In
practice, Employee Awards are made to a group of management employees.

All options are granted at one hundred percent (100%) of the fair market value
of the Common Stock of the Corporation on the date of the grant. Each stock
option terminates not more than ten (10) years after the date of the grant.
Options are exercisable in such installments as may be determined by the
Committee. Payment for stock purchased on the exercise of a stock option must be
made in full at the time the stock option is exercised. Options may not be
assigned or transferred, other than by will or the laws of descent or
distribution.

The Board of Directors may, at any time, terminate and, from time to time, may
amend or modify the 1996 Plan, without approval of the Corporation's
shareholders, except to the extent that such shareholder approval is required by
applicable law or regulation. There is no set termination date for the 1996
Plan.

No stock options were granted during 2004, while 65,055 options were exercised
and no options were terminated. A total of 448,488 options remain unexercised as
of the record date and 20,948 options are available for future grants.

2004 RECOGNITION AND RETENTION PLAN

The 2004 Recognition and Retention Plan (the "RRP") was adopted by the Board of
Directors of the Corporation, approved by its shareholders and became effective
on April 21, 2004. The RRP functions as a long-term incentive plan and enables
certain members of the Compensation Committee of the Board of Directors of the
Corporation (the "RRP Committee") to grant awards of restricted Common Stock to
key officers, employees, Directors and affiliates of the Corporation and the
Bank. Each restricted stock award shall vest annually in equal installments over
an eight (8)-year period, commencing on the first anniversary of the grant,
unless a vesting schedule is otherwise determined by the RRP Committee, and may
be subject to other terms and conditions consistent with the RRP. A restricted
stock award shall become one hundred percent (100%) vested upon the award
recipient's death, disability, retirement or after a change of control of the
Corporation, as each term is defined in the RRP. Restricted stock awards are
non-transferable. Award recipients have the right to receive all dividend
payments on their restricted stock awards and may vote such shares, whether or
not vested. The RRP is not subject to the Employee Retirement Income Security
Act of 1974, as amended, and is not a tax-qualified plan under the Internal
Revenue Code.

As required by the terms of the RRP, the Corporation has established a trust and
contributed certain amounts of money or property as determined by the Board of
Directors at its discretion. No contributions by participants are permitted. The
trustee will invest the assets of the trust primarily in shares of the
Corporation's Common Stock that will be used to make the restricted stock
awards. The trust was originally authorized to purchase up to 88,100 shares of
Common Stock, which number increased to 92,505 due solely to a five percent (5%)
stock dividend paid on May 18, 2004, and cannot purchase more than this limit.
All of the authorized shares of Common Stock were granted as restricted stock
awards in 2004.

The Board of Directors has the authority to suspend or terminate the RRP in
whole or in part at any time, by giving written notice to the RRP Committee,
provided there are no outstanding restricted stock awards that have not yet
become vested. Upon termination of the RRP, the trustee will make distributions
from the trust as directed by the RRP Committee and will return any remaining
assets of the trust to the Corporation.

LONG-TERM INCENTIVE PLANS AND RETIREMENT PLANS

As set forth below, executive officers and employees are eligible to participate
in the Westbank Money Purchase Pension Plan.

The Bank maintains a Money Purchase Pension Plan (the "Plan") available to
employees of the Corporation and the Bank. Full-time employees become eligible
to participate in the Plan when they have both (i) reached the Age of 20-1/2
years and (ii) completed six (6) months of service (as defined in the Plan).

Contributions to the Plan may be made by both the Bank and a participant. The
Bank's contributions will be made to the Plan whether or not a participant
chooses to contribute. The Bank's annual contribution to each participant's
account for 2004 equals 7% of a participant's annual compensation, plus 5.7% of
a participant's annual compensation in excess of the participant's Social
Security Taxable Wage Base.


DIRECTOR COMPENSATION

During 2004, Directors of the Corporation who are not salaried employees
received Directors' fees of $14,000. The Chairman of the Board of Directors
received annual remuneration of $19,500, while the Clerk of the Corporation
received an annual fee of $16,500. Directors who are also salaried employees
receive no additional compensation for their services as Directors of the
Corporation.


1995 DIRECTORS STOCK OPTION PLAN

In February 1995, the Board of Directors of the Corporation unanimously adopted
the 1995 Directors Stock Option Plan (the "1995 Plan"), which was approved by
the shareholders at the Annual Meeting in April 1995.

The 1995 Plan is administered by the non-employee Directors. The purpose of the
1995 Plan is to enhance the Corporation's ability to attract and retain highly
qualified individuals to serve as members of the Corporation's Board of
Directors and to provide additional incentives to non-employee Directors to
promote the success of the Corporation.

On each anniversary date of the 1995 Plan, each eligible Director is granted an
option to purchase one thousand (1,000) shares of the Corporation's Common
Stock. Each stock option terminates not more than ten (10) years after the date
of the grant. Payment for stock purchased on the exercise of an option must be
made in full at the time the stock option is exercised. Options may not be
assigned or transferred, other than by will or the laws of descent or
distribution. A total of 14,838 options were exercised during 2004.

The Plan expired as of February 15, 2005.

                                       21


1996 STOCK INCENTIVE PLAN

On February 21, 1996, the Board of Directors adopted the Westbank Corporation
1996 Stock Incentive Plan (the "1996 Plan"), which was approved by the
shareholders at the Annual Meeting in April 1996.

The 1996 Plan authorizes the automatic grant of non-qualified stock options
("Director Stock Options") to non-employee Directors ("Eligible Directors"),
upon the terms and conditions set forth in the 1996 Plan. The 1996 Plan is
intended to provide incentives and rewards for employees and Eligible Directors
(i) to support the Corporation's business and human resource strategies and the
achievement of its goals, and (ii) to associate the interests of employees and
Eligible Directors with those of the Corporation's shareholders.

No Director stock option may be exercisable later than twenty (20) years and one
(1) day from the date of its grant. However, if an Eligible Director ceases to
be an Eligible Director for any reason, all Director stock options that are
otherwise exercisable shall terminate on the earlier of three (3) years after
such cessation date or the expiration date, whichever comes first. A total of
5,520 Director stock options were exercised and 8,000 options were cancelled
during 2004.

The Directors' portion of the plan has expired.


CARGILL BANK DIRECTORS AND OFFICERS STOCK OPTION PLAN

On September 7, 2001, Cargill Bank, a wholly owned subsidiary of the
Corporation, merged with and into Park West Bank and Trust Company, a wholly
owned subsidiary of the Corporation, and presently operates under the name
Westbank.

During 1992, Cargill Bancorp, Inc. adopted a stock option plan for its Directors
and officers, which plan is now administered by the Corporation. All options
expire fifteen (15) years after the date of the grant. A total of 3,363 options
were exercised during 2004, while no options terminated and 6,091 options remain
unexercised. No options are available for future grants.


EMPLOYEE STOCK OWNERSHIP PLAN

On January 1, 1989, the Corporation's Employee Stock Ownership Plan (the "ESOP")
became effective. The ESOP is administered and otherwise governed by the
provisions of the ESOP and a related Trust Agreement. Pursuant to the terms of
the ESOP, the Trustee may invest the ESOP's trust assets in, among other
investments, shares of the Common Stock of the Corporation. As of the record
date, no shares of the Common Stock of the Corporation were owned by the ESOP
Trust.

                                       22


DIVIDEND REINVESTMENT PLAN

In 1989, the Corporation implemented a Dividend Reinvestment and Common Stock
Purchase Plan (the "Dividend Reinvestment Plan"), which was amended during 1995
and the amendment was approved by the shareholders at the 1995 Annual Meeting.
Pursuant to the amended Dividend Reinvestment Plan, shareholders of the
Corporation's Common Stock may invest all or a portion of that shareholder's
quarterly cash dividend, plus up to $10,000 per calendar quarter, in additional
shares of the Corporation's Common Stock. The Dividend Reinvestment Plan was
amended in 2002 to increase by 500,000 the number of shares reserved for
issuance thereunder. The 2002 amendment was approved by shareholders at the 2002
Annual Meeting. During 2004, 34,076 shares of the Corporation's Treasury Stock
were reissued through the Dividend Reinvestment and Common Stock Purchase Plan.
