                                  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 2000 Annual Meeting of
Shareholders of the Corporation to be held at the Carriage House at Storrowton
Tavern, 1305 Memorial Avenue, West Springfield, Massachusetts 01089 on
Wednesday, April 19, 2000 at 9:00 AM and at any adjournments thereof.

The close of business on March 6, 2000 has been fixed as the record date for
determination of shareholders of the Corporation entitled to notice of and to
vote at the 2000 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 2000 Annual Meeting of
Shareholders is 4,273,119. 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 2000 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 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 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 ten members. Following
the election of Directors at the 2000 Annual Meeting of Shareholders, the
Corporation's Board of Directors shall consist of nine members.

Seven Directors will continue to serve after the 2000 Annual Meeting of
Shareholders. In accordance with the By-Laws of the Corporation, two nominees
shall be elected to serve a three-year term until the 2003 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 2000 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.

                        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 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 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:

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

During 1995, the Corporation engaged the firm of Deloitte & Touche LLP to review
the Bank's retirement plan for executive officers. As a result of this review,
the Compensation Committee adopted the Westbank Supplemental Executive
Retirement Plan (the "Supplemental Plan"). The purpose of the Supplemental Plan
is to provide executives with retirement benefits that are comparable to those
provided to its other employees.

In early 1997, 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 ("The Incentive Compensation Plan"). The
Incentive Compensation Plan was adopted by the Compensation Committee and is
used as a guide in determining executive officer compensation.

During 1999, the Chief Executive Officer, Donald R. Chase, received a salary
increase of $34,500, an increase of fifteen percent (15%) 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 1998. In addition, as a result of The
Incentive Compensation Plan, Mr. Chase received a cash bonus of $50,600. In
addition, the Corporation contributed $20,323 to the Supplemental Plan for the
benefit of Mr. Chase.

                                        8
   11
The other executive officers named in the Summary Compensation Table, Messrs.
Briggs and Lilly, were granted a salary increase of fifteen percent (15%) during
1999, based on the Corporation's and their individual performance.

The Compensation Committee believes that the 1999 compensation of executive
officers is reasonable, given the Corporation's performance and utilizing the
criteria listed above.

Respectfully submitted by:

         Ernest N. Laflamme, Jr.                Mark A. Beauregard
              Chairman                          Leroy F. Jarrett

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 was amended by shareholders at the Corporation's 1994 Annual
Meeting, which amendment increased the number of shares of Common Stock reserved
thereunder by 200,000 shares.

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 be 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 1999.

A total of 3,301 options were exercised in 1999. A total of 1,155 options were
terminated during 1999 and a total of 39,828 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 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 83,500 incentive stock options were granted during 1999, while no
options were exercised. A total of 312,000 options remain unexercised as of the
record date.

LONG-TERM INCENTIVE PLANS AND RETIREMENT PLANS

The Corporation does not maintain any "Long-Term Incentive Plans" for its
executive officers.

The corporation has no pension, profit sharing or similar plans for its
executive officers or employees. As set forth below, however, the executive
officers and employees are eligible to participate in the Park West Money
Purchase Pension Plan.

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

Contributions to the Plan may be made by Park West, Cargill and a participant.
Park West and Cargill's contributions will be made to the Plan whether or not a
participant chooses to contribute. The annual contribution by Park West to each
participant's account for 1999 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. During 1999, Park West Contributed $16,182
for the account of Donald R.
Chase and $16,182 each for the accounts of Messrs. Briggs and Lilly.

During 1999, Park West contributed in the aggregate $48,546 for the accounts of

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

Directors and to provide additional incentives to non-employee Directors to
promote the success of the Corporation.

Under the 1995 Plan, eligible Directors were granted options to purchase 1,000
shares at an exercise price of $12.00 per share during 1999. On each anniversary
of the effective date of the 1995 Plan, each eligible Director shall be granted
an option to purchase 1,000 shares of the Corporation's Common Stock. A total of
10,000 options were granted during 1999 at an option price of $12.00 per share
and a total of 9,000 options were granted during 2000 at an exercise price of
$8.75. A total of 39,000 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

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, Eligible Directors were granted options to purchase 1,000
shares at an exercise price of $10.50 per share during 1999. At the 2000 Annual
Meeting and each year thereafter until the Meeting in 2001, each Eligible
Director who was an Eligible Director immediately preceding such Annual Meeting
and who has been elected as a Director at such Annual Meeting shall
automatically be granted Director Stock Options for 1,000 shares of Westbank
Common Stock if, but only if, the return on common equity of Westbank as set
forth in Westbank's Annual Report to Shareholders for the immediately preceding
fiscal year is equal to or greater than 12%.

Based on the Corporation's 1999 financial results, each Eligible Director is
entitled to a grant of 1,000 shares of Westbank Common Stock for 2000 at an
exercise price that is equal to the fair market value of the stock on the date
of the grant.

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. No Director Stock Options
were exercised during 1999.


CARGILL BANK DIRECTORS AND OFFICERS STOCK OPTION PLAN

During 1992, Cargill Bancorp, Inc. adopted a Stock Option Plan for its Directors
and officers. All options expire fifteen (15) years after the date of the grant.
A total of 21,954 options were exercised during 1999 and 43,908 options remain
unexercised.
No options are available for future grants.


EMPLOYMENT AND TERMINATION AGREEMENTS

Donald R. Chase has entered into a Termination Agreement with Park West
regarding termination of employment subsequent to a "change in control" of Park
West 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 times his average annual compensation
for the previous five years.

MISCELLANEOUS

During 1999, certain of the Corporation's executive officers, Directors and
nominees for Director, beneficial owners of more than 5% of the outstanding
common stock of the Corporation and members of their immediate family and
associates have had, and expect to have in the future, transactions in the
ordinary course of business with Park West and/or Cargill, including borrowings,
on substantially the same terms, including interest rates and collateral, as
those prevailing at the time for comparable transactions with other persons, and
not involving more than normal risk of collectibility or presenting other
unfavorable features.

                          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. During 1999, 54,626 shares of the
Corporation's Common Stock were purchased through the Dividend Reinvestment and
Common Stock Purchase Plan.


                        RATIFICATION OF THE SELECTION OF
                          CERTIFIED PUBLIC ACCOUNTANTS

Deloitte & Touche LLP ("Deloitte"), certified public accountants, have served as
auditors for the Corporation since 1994 and, subject to ratification by the
shareholders, that firm has been chosen by the Board of Directors to act as the
Corporation's auditor for 2000. During 1999, Deloitte provided audit services in
connection with the examination of the financial statements of the Corporation,
Park West and Cargill, and other accounting matters. Neither Deloitte nor any of
its partners has any direct or indirect financial interest in, or connection
with (other than as independent auditor), the Corporation, Park West or Cargill.

A representative of Deloitte & Touche LLP is expected to be present at the
Corporation's 2000 Annual Meeting of Shareholders. He/she will have the
opportunity to make a statement if he/she desires to do so and will be available
to respond to appropriate questions.

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