                                  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 2003 Annual Meeting of
Shareholders of the Corporation to be held at the Best Western Sovereign Hotel &
Conference Center, 1080 Riverdale Street, West Springfield, Massachusetts, on
Wednesday, April 16, 2003 at 9:00 AM and at any adjournments thereof.

The close of business on March 3, 2003 has been fixed as the record date for
determination of shareholders of the Corporation entitled to notice of and to
vote at the 2003 Annual Meeting of Shareholders. 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 2003 Annual Meeting of
Shareholders is 4,378,206. Each share of Common Stock is entitled to one vote.

The affirmative vote of a majority of the shares of Common Stock of the
Corporation represented at the 2003 Annual Meeting is required to appoint the
auditor of the Corporation. The affirmative vote of a plurality of the votes
cast by shareholders is required to elect Directors.

Execution of the enclosed proxy will not affect the shareholder's right to
attend the 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.







                                        2



ELECTION OF DIRECTORS


The By-Laws of the Corporation provide, in substance, that the Board of
Directors shall be divided into three 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 members.

Six Directors will continue to serve after the 2003 Annual Meeting of
Shareholders. In accordance with the By-Laws of the Corporation, three (3)
nominees shall be elected to serve a three(3)-year term, until the 2006 Annual
Meeting of Shareholders, and 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 2003 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.

The following tables name the individuals nominated for Director and those
Directors of the Corporation who will continue to serve after the Meeting, and
indicate their age, the period of time they have served as Director of the
Corporation or its predecessor, their position with the Corporation, and their
principal occupation or employment. No nominee or Director holds a directorship
in any corporation, other than the Corporation, with a class of securities
registered pursuant to Section 12 of the Securities and Exchange Act of 1934 or
subject to the requirements of Section 15(d) of such Act or any corporation
registered as an investment company under the Investment Company Act of 1940.

REPORT OF THE AUDIT COMMITTEE

THE FOLLOWING REPORT OF THE AUDIT COMMITTEE DOES NOT CONSTITUTE SOLICITING
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 of the Board of Directors has developed a charter for the
Committee, which was approved by the full Board on May 16, 2001. The complete
text of the charter, which reflects standards set forth in SEC regulations and
Nasdaq rules, was included in the 2001 Proxy Statement.

As set forth in more detail in the charter, the Audit Committee's primary
responsibilities fall into three (3) broad categories:

     o    first, the 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 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); and

     o    third, the 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
          interests; and review of the activities and recommendations of the
          Corporation's internal and external auditing programs.

The Committee has implemented procedures to ensure that during the course of
each fiscal year it devotes the attention that it deems necessary or appropriate
to each of the matters assigned to it under the Committee's charter. To carry
out its responsibilities, the Committee met five (5) times during Fiscal Year
2002.

In overseeing the preparation of the Corporation's financial statements, the
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, and the Committee discussed the statements with both
management and the outside auditors. 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).





                                        6


With respect to the Corporation's outside auditors, the Committee, among other
things, discussed with Deloitte & Touche, LLP matters relating to its
independence, including the disclosures made to the Committee as required by the
INDEPENDENCE STANDARDS BOARD STANDARD NO. 1 (INDEPENDENCE DISCUSSIONS WITH AUDIT
COMMITTEES). Listed below are aggregate fees billed to the Corporation for the
fiscal year ended December 31, 2002 by the Corporation's principal accounting
firm, Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmatsu and
their respective affiliates (collectively, "Deloitte"):


     ======================================================================
          Audit Fees                                  $146,000
          All Other Fees                              $ 21,095 (a)(b)


     (a)  Includes fees for tax, compliance, consulting and other non-audit
          services.
     (b)  The Audit Committee has considered whether the provision of these
          services is compatible with maintaining the principal
          accountant's independence.
     ======================================================================


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, 2002, for filing with the Securities and
Exchange Commission.

Section 16(a) of the Securities and Exchange Act of 1934, as amended (the

holders of more than 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. The Corporation believes that, during the fiscal year ended
December 31, 2002, all such persons complied with all Section 16(a) filing
requirements. In making this statement, the Corporation has relied upon the
written representations of its Directors and Executive Officers.

                        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 of 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 three (3)
primary components: base salary, cash incentive compensation and stock options,
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 plans 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 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.




                                       10



During 2001, the Compensation Committee engaged Thomas Warren & Associates, Inc.
to assist in establishing salary 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.

During 2002, the Chief Executive Officer, Donald R. Chase, received a salary
increase of $29,556, an increase of eight percent (8%) of his base salary. The
increase was recommended by the Compensation Committee following its evaluation
of Mr. Chase's performance as Chief Executive Officer and the overall
performance of the Corporation for 2001. In addition, as a result of The
Incentive Compensation Plan, Mr. Chase received a cash bonus, payable in 2003,
of $158,986 based on the Corporation's 2002 performance.

During 2002, the Compensation Committee, with ratification by the full Board of
Directors, granted stock option awards to Mr. Chase totaling 102,375 shares that
vest, at 34,125 shares each year, over a three(3)-year period beginning in 2002.

The Compensation Committee believes that the 2002 compensation of executive
officers was reasonable, given the Corporation's performance and utilizing the
criteria listed above.

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 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 option 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 2002.

A total of 19,715 options were exercised in 2002. A total of 2,215 options were
terminated during 2002 and a total of 10,998 options remain unexercised as of
the record date.


1996 STOCK INCENTIVE PLAN

On February 21, 1996, the Board of Directors unanimously 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 was amended
at the 2002 Annual Meeting of Shareholders to increase the number of shares
reserved for issuance thereunder by 200,000.

The 1996 Plan is administered by the Compensation Committee (the "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 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 10 years after the date of the grant. Options are exercisable in such
installments as may be determined by the Committee. Payment of 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 Westbank 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.

A total of 199,900 stock options were granted during 2002, while 5,500 options
were exercised and 1,500 options were terminated. A total of 549,000 options
remain unexercised as of the record date and 19,100 options are available for
future grants.

DIRECTOR COMPENSATION

During 2002, Directors of the Corporation who are not salaried employees
received Directors' fees of $12,000. The Chairman of the Board of Directors
received annual remuneration of $17,500, while the Clerk of the Corporation
received an annual fee of $14,500. Directors who are also salaried employees
receive no additional compensation for their services as Directors of the
Corporation.

The Westbank Directors Supplemental Retirement Plan ("the Directors Retirement
Plan") was established during 2001. Under the Directors Retirement Plan, the
Bank provides post-retirement benefits for non-employee Directors who retire
from the Board after reaching age seventy-two (72). The retirement benefit is in
the amount of seventy-five percent (75%) of the Director's final compensation at
retirement and is payable for the life of the Director. Expenses recognized for
Directors under the Directors Retirement Plan were $134,411 in 2002.


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 of the effective date of the 1995 Plan, each eligible
Director is granted an option to purchase 1,000 shares of the Corporation's
Common Stock. A total of 8,000 options were granted on February 15, 2003 at an
option price of $13.92 per share. A total of 13,000 shares remain available for
future grants under the 1995 Plan.

Each stock option terminates not more than 10 years after the date of the grant.
Payment of 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 3,000 options were exercised during 2002.

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 nonqualified 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 Westbank'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 Westbank's shareholders. Under the 1996 Plan, no
Director stock options were granted in 2002.

No Director Stock Option may be exercisable later than twenty years and one 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 which are otherwise
exercisable shall terminate on the earlier of three years after such cessation
date or the expiration date, whichever first occurs. A total of 4,875 Director
Stock Options were exercised and 2,000 Options were terminated during 2002.


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 operate 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 20,965
options were exercised during 2002, while no options terminated and 11,966
options remain unexercised. No options are available for future grants.


EMPLOYMENT AND TERMINATION AGREEMENTS

Donald R. Chase has entered into a Termination Agreement with the Bank regarding
termination of employment subsequent to a "change in control" of the Bank as
defined in the Termination Agreement. Following the occurrence of a change in
control, if Mr. Chase's employment is terminated (except because of retirement,
death, disability or for "cause" as defined in the Termination Agreement) or is
voluntarily terminated by Mr. Chase for "good reason" as defined in the
Termination Agreement, then Mr. Chase shall be entitled to a lump sum payment
approximately equal to three (3) times his average annual compensation for the
previous five (5) years.

                          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.




                           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 2002, 42,310 shares of the Corporation's Treasury Stock
were reissued through the Dividend Reinvestment and Common Stock Purchase Plan.

                        RATIFICATION OF THE SELECTION OF
                          CERTIFIED PUBLIC ACCOUNTANTS


The Board of Directors has solicited proposals from various accounting firms to
act as the Corporation's certifying accountants for the fiscal year ending
December 31, 2003. After reviewing the proposals received, the Board of
Directors approved a recommendation of the Audit Committee that the Corporation
change its certifying accountants from the firm of Deloitte & Touche LLP
("Deloitte") to Grant Thornton LLP ("Grant"). If ratified by the shareholders,
the client/auditor relationship between the Corporation and Deloitte will be
terminated effective with the completion of the 2002 financial audit. Deloitte's
audit duties for the Corporation will conclude after the preparation of the 2002
Annual Report of the Corporation and the presentation of the 2002 Annual Report
of the Corporation to the 2003 Annual Meeting of Shareholders.

Deloitte's report on the Corporation's financial statements during the two most
recent fiscal years preceding the date hereof contain no adverse opinion or
disclaimer of opinions, and was not qualified as to audit scope or accounting
principles.

During the last two fiscal years and the subsequent interim periods preceding
the date hereof, there were no disagreements between the Corporation and
Deloitte on any matters of accounting principle or practices, financial
statements disclosure, or auditing scope or procedure, which disagreements, if
not resolved to the satisfaction of Deloitte, would have caused Deloitte to make
a reference to the subject matter of disagreements in connection with its
reports.

None of the "reportable events" described under Item 304(a)(1)(v) of Regulation
S-K promulgated under the Securities Exchange Act of 1934 ("Regulation S-K")
occurred within the Corporation's two most recent fiscal years and any
subsequent interim periods preceding the date hereof.

During the last two fiscal years and the subsequent interim periods preceding
the 2003 fiscal year, the Corporation did not consult Deloitte regarding any of
the matters or events set forth in Item 304(a)(2)(I) and (ii) of Regulation S-K.

Representatives of Deloitte and Grant are expected to attend the 2003 Annual
Meeting of Shareholders and will be available to respond to appropriate
questions.

The Board of Directors recommends a vote FOR ratification of the selection of
Grant Thornton LLP as the Corporation's auditors and, unless otherwise directed,
proxies will be voted in favor of this selection.
