Dear Shareholder:

         You are cordially invited to attend a Special Meeting of Shareholders
of Cargill Bancorp, Inc. ("Cargill"), which will be held at the Heritage Road
Cafe, 5 Heritage Road, Putnam, Connecticut, at 10:00 a.m., local time, on
Wednesday, December 16, 1998 (the "Special Meeting").

         At the Special Meeting, you will be asked to consider and vote on an
Affiliation and Merger Agreement (the "Merger Agreement") by and among Cargill,
Cargill Bank, Park West Bank and Trust Company and Westbank Corporation
("Westbank") pursuant to which Cargill will merge with and into Westbank and
Cargill Bank will become a subsidiary of Westbank (the "Merger"). Each
outstanding share of Cargill Common Stock (other than Dissenting Shares, if any)
will become and be converted into shares of Westbank Common Stock, in an amount
as determined under the Merger Agreement.

         The attached Proxy Statement - Prospectus is intended to provide you
with the information that you will need to make an informed decision regarding
how you should vote on the proposed Merger. It also serves as a Prospectus for
Westbank, describing the investment in Westbank that you will be making if the
Merger is approved, and the process for exchanging your Cargill Common Stock for
Westbank Common Stock. A copy of the Merger Agreement is attached to the Proxy
Statement - Prospectus as Appendix A. I urge you to read this information
carefully before voting on the proposed Merger.

         AFTER CAREFUL CONSIDERATION, THE BOARD OF DIRECTORS OF CARGILL BELIEVES
THAT THE MERGER IS FAIR AND IN THE BEST INTERESTS OF CARGILL AND ITS
SHAREHOLDERS AND UNANIMOUSLY RECOMMENDS THAT YOU VOTE IN FAVOR OF THE APPROVAL
AND ADOPTION OF THE MERGER AGREEMENT AT THE SPECIAL MEETING.

         Your vote is important regardless of the number of shares you own.
Approval of the Merger requires the affirmative vote of the holders of not less
than two-thirds of all issued and outstanding shares of Cargill Common Stock,
whether or not such shares are present at the Special Meeting. An abstention or
non-vote will have the effect of a vote against the Merger Agreement. Each
shareholder, even though he or she now plans to attend the Special Meeting, is
requested to sign, date and return the enclosed Proxy without delay in the
enclosed postage-paid return envelope. You may revoke your Proxy at any time
prior to its exercise. Any shareholder present at the Special Meeting or at any
adjournments or postponements thereof may revoke his or her Proxy and vote
personally on each matter brought before the Special Meeting. Because of the
required two-thirds vote, it is particularly important that all shareholders
vote at the Special Meeting. Your prompt cooperation is greatly appreciated.

                                        Sincerely,

                                        /s/ Raymond P. Faucher, Sr.

                                        Raymond P. Faucher, Sr.

         Cargill, Cargill Bank, Park West Bank and Trust Company and Westbank
         Corporation ("Westbank") and the transactions contemplated thereby,
         including the Merger of Cargill with and into Westbank (the "Merger")
         upon the terms and subject to the conditions set forth in the Merger
         Agreement as more fully described in the accompanying Proxy
         Statement-Prospectus. A copy of the Merger Agreement is attached as

         related documents are attached as exhibits thereto; and

         Such other matters as may properly come before the Special Meeting or

         NOTE:    The Cargill Board of Directors is not aware of any other
                  business to come before the Special Meeting.

         The Cargill Board of Directors has fixed the close of business on
November 5, 1998 as the record date (the "Record Date") for the determination of
shareholders entitled to notice of and to vote at the Special Meeting and any
adjournments or postponements thereof. Only shareholders of record at the close
of business on such date are entitled to notice of and to vote at the Special
Meeting and any adjournments or postponements. The presence, in person or by
proxy, of one-third of the aggregate number of shares of Cargill Common Stock
outstanding on the Record Date is necessary to constitute a quorum at the
Special Meeting.
   
    

                                        By Order of the Board of Directors,
                                        

                                        Secretary

                                 (413) 747-1400


                         PROXY STATEMENT AND PROSPECTUS

            565,096 shares of Common Stock, par value $2.00 per share
                             of Westbank Corporation

         The Boards of Directors of Westbank Corporation ("Westbank") and
Cargill Bancorp, Inc. ("Cargill") have agreed that Westbank will acquire Cargill
in a merger transaction (the "Merger"). Cargill's subsidiary, Cargill Bank, will
become a subsidiary of Westbank, but will remain a separate Connecticut
chartered stock savings and loan association and will stay headquartered in
Putnam, Connecticut. The Merger will enable Cargill Bank to offer more products
and services to customers and will enable Westbank to extend its operations into
the Connecticut market, and we believe it will benefit both companies and
shareholders.

         If you are a Cargill shareholder, you will receive shares of Westbank
common stock ("Westbank Common Stock") for each share of Cargill common stock
("Cargill Common Stock") you own on the date of the Merger, as described below.

         YOUR VOTE IS VERY IMPORTANT. The Merger cannot be completed unless the
shareholders of Cargill approve it. Cargill has scheduled a special meeting (the
"Special Meeting") for its shareholders to vote on the Merger. The Special
Meeting to vote on the Merger will take place on Wednesday, December 16, 1998,
at 10:00 a.m. at the Heritage Road Cafe, 5 Heritage Road, Putnam, Connecticut.

         Whether or not you plan to attend the Special Meeting, please take the
time to vote by completing and mailing the enclosed proxy card to us. If you
complete and return your card but don't indicate how you want to vote, your
proxy will be counted as a vote in favor of the Merger. If you don't return your
card or abstain from voting, the effect will be a vote against the Merger. If
you decide to attend the Special Meeting, you may vote in person even though you
have already submitted a proxy.

         This document serves as a Proxy Statement for the Special Meeting of
Cargill and as a Prospectus of Westbank with respect to shares of Westbank

Cargill Bank, is a Connecticut chartered stock savings and loan association that
provides a variety of deposit, loan and investment products and services to
small businesses and consumers. Cargill's principal executive offices are
located at 163 Providence Street, Putnam, Connecticut 06260. Its telephone

Cargill had total assets of $47,908,000, total deposits of $42,442,000, net
loans of $33,961,000 and shareholders' equity of $3,411,000.

   
WHAT CARGILL SHAREHOLDERS WILL RECEIVE (SEE PAGE 57)
    

         If you are a Cargill shareholder and the Merger is approved, you will
receive shares of Westbank Common Stock for each share of Cargill Common Stock
you own on the date of the Merger. To calculate the exact number of Westbank
shares you will receive, we will average the closing prices of Westbank Common
Stock for each of the 20 trading days that end five days before the date of the
Merger.

   
         For example, assume that the Merger was approved and had occurred on
July 15, 1998. The average closing price of Westbank Common Stock for the 20
days ending on July 10, 1998, five trading days prior to July 15, was $14.13. In
this example, you would have received $18.38 worth of Westbank Common Stock for
each share of Cargill Common Stock that you owned on July 15.
    




                                      -9-

   12



         In addition to Westbank Common Stock, you will also receive a check for
a small amount of cash instead of any fractional shares you might otherwise
receive. For instance, if you own 10 shares of Cargill Common Stock, they would
be converted into 13 shares of Westbank stock in the Merger, based on the
anticipated exchange ratio described in the Merger Agreement of 1.3008 X 10. If
the average closing price was $14.13, instead of receiving a .008 shares of
Westbank Common Stock, you would be paid $.11.


   
         Assuming that the actual average closing price was $10.625, the closing
price per share of Westbank Common Stock on October 30, 1998, the Exchange Ratio
would be 1.4167 and you would receive $15.05 worth of Westbank Common Stock for
each share of Cargill Common Stock that you own. In such event, if you own 10
shares of Cargill Common Stock, they would be converted into 14 shares of
Westbank Common Stock and $.18 in cash in the Merger based upon an exchange
ratio of 1.4167 x 10.      
    
   
         Cargill can terminate the Merger Agreement if the actual average
closing price of Westbank Common Stock is less than $12.00 per share, unless
Westbank agrees to issue more Westbank Common Stock so that you will receive at
least $17.00 value per share in Westbank Common Stock. However, Westbank is not
required to issue more shares, and it is possible under these circumstances that
the Cargill Board of Directors (the "Cargill Board") could conclude that
proceeding with the Merger at the lower price would still be in your best
interest and consistent with the Cargill Board's fiduciary duties and permit the
Merger to proceed without obtaining additional shareholder approval.
    
   
         Solely by way of example, if the $10.625 closing price of Westbank
Common Stock on October 30, 1998 were the actual average closing price and the
Cargill Board voted to terminate the Merger Agreement unless Westbank increased
the consideration, and if the Westbank Board chose to increase the consideration
to $17.00 worth of Westbank Common Stock (which it is not obligated to do), the
Exchange Ratio would be 1.6 and you would receive $17.00 worth of Westbank
Common Stock for each share of Cargill Common Stock that you own. In such event,
if you own 10 shares of Cargill Common Stock, they would be converted into 16
shares of Westbank Common Stock. 
    
         You should not send in your Cargill stock certificates until we notify
you to do so after the Merger takes place.

REASONS FOR THE MERGER

         After considering various alternatives that would allow it to improve
its overall performance and earnings potential, Cargill approached several
financial institutions, including Westbank, to discuss strategic alliances.
Cargill eventually focused on Westbank, believing that a combination of the two
companies could expand the resources of each and give both the opportunity to
enhance shareholder value and to offer a greater variety of products and
services. The ensuing negotiations resulted in the Merger Agreement.

                                      -10-
   13
         Both Westbank and Cargill recognize that the banking industry,
nationally and in New England, is undergoing substantial consolidation. Banking
laws and regulations now permit banks to offer new types of financial services
to businesses and consumers and have eliminated barriers to interstate
operations. Westbank and Cargill each offers various products and services not
currently provided by the other. By combining, we expect to become more
efficient and to be better positioned to expand beyond our current market areas.
Combining the companies should enable us to increase revenues, reduce costs and
improve services. We believe that our combined company will not only enable
Cargill to maximize long-term shareholder value while serving the interests of
its customers, suppliers, employees and community, but will also further the
interests of Westbank and its shareholders.

         In deciding to approve and recommend the Merger Agreement, our Cargill
Board considered a number of factors, including the financial strength, enhanced
prospects and opportunities for growth of the combined organization; the
potential benefits to our shareholders; the effects on our customers, suppliers,
employees and communities; the value of the stock Westbank offered and how it
compared with other preliminary, informal proposals made at the time; and the
opinions of our financial advisers that the stock being offered by Westbank is
fair from a financial point of view.

         You can find a more detailed discussion of the background to the Merger
Agreement and our reasons for the Merger in this Proxy Statement-Prospectus
under the heading entitled "THE MERGER," at page 41.

RECOMMENDATION TO SHAREHOLDERS

         The Cargill Board believes that the Merger is in your best interest and
unanimously recommends that you vote FOR the proposal to approve the Merger
Agreement.

   
REQUIRED VOTE; SHAREHOLDERS' AGREEMENTS (SEE PAGES 37 AND 69)
    

         The Merger Agreement must be approved by the holders of two-thirds of
all outstanding shares of the Common Stock of Cargill.

   
         The directors and executive officers of Cargill have agreed that they
will vote all 63,495 shares of Cargill stock owned or controlled by them in
favor of the Merger Agreement. This represents approximately 21.9% of the 
outstanding shares of Cargill.
    

   
OWNERSHIP OF WESTBANK FOLLOWING THE MERGER (SEE PAGE 70)
    

   
         Westbank expects to issue shares of its stock to Cargill shareholders
in connection with the Merger, which would constitute between 8% and 15% of the
outstanding stock of Westbank after the Merger. The shares will be listed for
trading on the Nasdaq National Market.

   14
   
MANAGEMENT AND OPERATIONS AFTER THE MERGER (SEE PAGE 70)
    

   
         After the Merger takes place, the management and Board of Directors of
Westbank and Cargill Bank will consist of those individuals who served
immediately prior to the Effective Time (as such term is defined below), except
that Donald R. Chase, the President and Chief Executive Officer and a director
of Westbank, will join the Board of Cargill Bank, and one of the current
directors of Cargill will join the Westbank Board of Directors (the "Westbank
Board"). In addition, such other individuals as may be designated by Westbank
will be asked to serve on the Cargill Bank Board to constitute a majority of the
Cargill Bank Board of Directors and a new President and Chief Executive Officer
for Cargill Bank will be appointed by Westbank to replace Robert G. Eggleston, 
Jr. who resigned in October 1998.
    

   
OPINIONS OF FINANCIAL ADVISERS (SEE PAGE 46)
    

   
         Cargill asked its financial adviser, Ostrowski & Company, Inc.
("O&Co.") for advice on the fairness of the amount that Westbank is offering to
Cargill shareholders in the Merger. O&Co. performed a number of analyses in
which it compared the companies' historical stock prices and other measures of
financial performance, compared the financial terms of the Merger to those of
other publicly announced transactions, and estimated the relative values of
Westbank and Cargill based on past and anticipated future performance and the
benefits that could be expected from the Merger. O&Co. delivered an opinion to
Cargill that the exchange ratio of Westbank stock for Cargill stock in the
Merger is fair to Cargill's shareholders from a financial point of view.
Northeast Capital & Advisors, Inc. ("NECA") also delivered an opinion to
Westbank stating that the exchange ratio of the Merger is fair from a financial
point of view to Westbank and its shareholders. These opinions are attached as
Appendix B and Appendix C to this Proxy Statement-Prospectus.
    

   
CONDITIONS TO THE MERGER (SEE PAGE 62)
    

         To complete the Merger, we must meet a number of conditions in addition
to obtaining the vote of our shareholders, including the following:

         - no law or injunction may effectively prohibit the Merger;

         - we must receive all necessary approvals of governmental authorities; 
           and

   
         - we must receive a legal opinion that the Merger will be treated as a
           tax-free reorganization under the Internal Revenue Code.
    

         In some instances, if we wish to waive a condition, we may be required
to resolicit the approval of the shareholders of Cargill.

   
TERMINATION OF THE MERGER AGREEMENT (SEE PAGE 64)
    

   
         In addition to terminating the Merger Agreement if Westbank's stock
price falls below $12.00 per share, unless Westbank increases the number of
shares of Westbank stock to be
    

                                      -12-

   15
 
   
exchanged for each share of Cargill stock, Cargill can decide to terminate the
Merger Agreement without completing the Merger, and either of Cargill or
Westbank can terminate the Merger Agreement, if any of the following occurs:
    

         - the Merger is not completed by March 31, 1999;

         - the Merger is not approved by Cargill shareholders;

         - a court or other governmental authority permanently prohibits the 
           Merger; or

         - the other party breaches or materially fails to comply with any of
           its representations, warranties or obligations under the Merger
           Agreement.

   
AMENDMENT, WAIVER AND EXTENSION OF THE MERGER AGREEMENT (SEE PAGE 64)
    

         We may amend the Merger Agreement at any time before the Merger
actually takes place, and may agree to extend the time within which any action
required by the Merger Agreement is to take place. Similarly, without
resoliciting and obtaining further approval from shareholders, Cargill can waive
the requirement that Cargill's shareholders must receive $17.00 per share if
Westbank's Common Stock price falls below $12.00 per share if the Cargill Board
concludes that proceeding with the Merger at the lower price would still be in
Cargill's Shareholders best interest and consistent with the Cargill Board's
fiduciary duties.

REGULATORY APPROVALS (SEE PAGE 64)

         The Merger must be approved by the Federal Reserve Board, the
Commissioner of the Connecticut Department of Banking and the Massachusetts
Board of Bank Incorporation, and Westbank has filed applications with those
agencies seeking the necessary approvals, which are still pending. Westbank must
notify the OTS after consummation of the Merger and request deregistration of
Cargill as a unitary savings and loan holding company. If the Federal Reserve
Board approves the Merger, the United States Department of Justice has up to 30
days in which to challenge such approval on antitrust grounds. It is possible
that some of these governmental authorities may impose conditions for granting
approval. We cannot predict with certainty whether we will obtain the required
regulatory approvals within the time frame contemplated by the Merger Agreement
or on conditions that would not be detrimental to either Westbank or Cargill or
the combined company.

   
CERTAIN FEDERAL INCOME TAX CONSEQUENCES (SEE PAGE 72)
    

         We have structured the Merger so that Westbank, Cargill and Cargill's
shareholders will not recognize any gain or loss for federal income tax purposes
in the Merger, except for taxes payable because of cash received by Cargill
shareholders instead of fractional Westbank shares or pursuant to the exercise
of dissenters' rights as described below.

STOCK OPTION AGREEMENT (SEE PAGE 66)

   
         In connection with the Merger Agreement, Cargill granted Westbank an
option to purchase up to 84,804 shares of Cargill Common Stock at an exercise
price of $12.00 per share. Westbank
    

                                      -13-

   16
   
may exercise this option only if certain events ordinarily associated with
another party attempting to "break up" the Merger and acquire Cargill occur. As
of this date, none of those events has occurred. Under the option agreement, if
any such event did occur and Westbank were entitled to exercise the option, it
would also be entitled to consequential damages, as well as a reimbursement of
its costs and fees of $150,000 from Cargill. The option and the fees were
granted as an incentive to Westbank to proceed with the Merger, and may
discourage other persons who might be interested in acquiring Cargill.

APPRAISAL RIGHTS AND DISSENTING SHAREHOLDERS (SEE PAGE 39)

         Holders of Cargill Common Stock who do not vote in favor of the Merger
and who follow certain procedures set forth in the law will be entitled to
dissenters' rights under Section 262 of Title 8 of the Delaware General
Corporation Law. The text of the pertinent statutory provisions is attached as
Appendix D. Holders of Westbank Common Stock will not vote and do not have
dissenters' rights in connection with the Merger.
    

CERTAIN DIFFERENCES IN THE RIGHTS OF SHAREHOLDERS

   
         Once the Merger occurs, Cargill's shareholders (other than dissenting
shareholders) will automatically become shareholders of Westbank, and their
rights will be governed by Massachusetts law rather than Delaware law and by
Westbank's corporate governing documents, including its articles of organization
and bylaws. You can find a detailed discussion of the differences between the
rights of Cargill and Westbank shareholders in this Proxy Statement-Prospectus
under the heading entitled "COMPARISON OF THE RIGHTS OF HOLDERS OF WESTBANK
COMMON STOCK AND CARGILL COMMON STOCK" at page 101.

         On July 1, 1998, 1998, Westbank announced a quarterly dividend of $.10
per share payable on July 20, 1998 to holders of record as of the close of
business on July 14, 1998. On October 1, 1998, Westbank announced a quarterly
dividend of $.10 per share payable on October 20, 1998 to holders of record as
of the close of business October 14, 1998.
    

   
         On July 14, 1998, the last business day before the Merger was
announced, the closing price for a share of Westbank stock was $14.13 and the
most recent sales price for a share of Cargill stock was $11.50. If $14.13 had
been the average of the closing bid prices under the Merger Agreement, a Cargill
shareholder receiving Westbank stock in exchange for a share of Cargill stock on
that day under the terms of the Merger Agreement would have received shares of
Westbank stock with a value of $18.38 ($14.13 X 1.3008). On October 30, 1998,
the closing price of the Westbank Common Stock was $10.625 per share. If that
was the actual average closing price, a Cargill shareholder would receive stock
with a value of $15.05 [$10.625 X 1.4167]. However, Cargill can terminate the
Merger Agreement if the actual average closing price of Westbank Common Stock is
less than $12.00 per share, unless Westbank agrees to issue more Westbank Common
Stock so that Cargill Shareholders will receive at least $17.00 value per share
in Westbank Common Stock. However, Westbank is not required to issue more
shares, and it is possible under these circumstances that the Cargill Board
could conclude that proceeding with the Merger at the lower price would still be
in your best interest and consistent with the Cargill Board's fiduciary duties
and permit the Merger to proceed without obtaining additional shareholder
approval.
    

   
         Assuming that the $10.625 closing price of Westbank Common Stock on 
October 30, 1998 was the actual average closing price and that the Cargill 
Board voted to terminate the Merger Agreement unless Westbank increased the 
consideration, and assuming that the Westbank Board chose to increase the 
consideration to $17.00 worth of Westbank Common Stock, the Exchange Ratio 
would be 1.6 and Cargill Shareholders would receive $17.00 worth of Westbank 
Common Stock for each of their shares of Cargill Common Stock. In such event, a 
Cargill shareholder owning 10 shares of Cargill Common Stock, would receive 16 
shares of Westbank Common Stock.

FUTURE WESTBANK ACQUISITION ACTIVITY

         Both nationally and in New England, the banking industry is undergoing
a period of consolidation marked by numerous mergers and acquisitions. Westbank
has no formal plan to acquire other banking or thrift institutions, but it may
occasionally be presented with opportunities before or after the Merger to
acquire existing institutions that could expand and strengthen Westbank's market
position. If such an opportunity arises, Westbank may engage in discussions or
negotiations about the target company, and may acquire or seek to acquire such
entity. If the purchase price for any such acquisition were to include a premium
over the target's book or market value, which is not unusual, Westbank's book
value might be diluted, at least in the short term.

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

         Each company makes forward-looking statements in this document that are
subject to risks and uncertainties. Forward-looking statements include the
information concerning possible or assumed future results of operations of our
companies set forth under "Recommendation of the Cargill Board and Reasons for
the Merger," "Recommendation of the Westbank Board and Reasons for the Merger"
and "Opinions of Financial Advisers" and statements preceded by, followed by or
including words such as "believes," "anticipates," "plans", "expects" and
similar expressions. For those statements, we claim the protection of the safe
harbor for forward-looking statements contained in the Private Securities
Litigation Reform Act of 1995. You should understand that the following
important factors, in addition to those discussed elsewhere in this document and
the documents we incorporate by reference, could affect the future results of
the companies and could cause those results to differ materially from those
expressed in our forward-looking statements:

         1.       our revenues after the Merger are lower than we expect, our
                  restructuring charges are higher than we expect, we lose more
                  deposits, customers or business than we expect, or our
                  operating costs after the Merger are greater than we expect;

                              RECENT DEVELOPMENTS
    
Westbank

   
         Westbank reported net income of $910,000 or $0.24 basic and diluted
earnings per share for the third quarter ended September 30, 1998, an 11%
increase compared to $818,000 or $0.23 basic and diluted earnings per share for
the quarter ended September 30, 1997.
    

     For the nine month period ended September 30, 1998, earnings totaled 
$2,600,000, a 20% increase compared to earnings of $2,200,000 for the nine 
months ended September 30, 1997. Basic earnings per share was $0.70 and $0.63 
for the nine months ended September 30, 1998 and 1997, respectively. Diluted 
earnings per share was $0.68 and $0.61 for the nine months ended September 30, 
1998 and 1997, respectively.

     As of September 30, 1998 assets totaled $357,000,000, an increase of 11% 
over the same period in 1997. Total loans grew by $14,900,000 or 6% while 
investments increased to $67,300,000, a growth of $14,700,000 or 28%.

   
     Westbank also showed a 7% or $22,200,000 increase in deposits compared to 
September 30, 1997. The growth in all deposit categories is attributable to 
Park West's new relationship account and expanded branch network.
    

     For the first nine months of 1998, Westbank's return on average assets was 
1.07% and the return on average equity totaled 13.72%.

Cargill

     Cargill reported net income of $121,000 for the year ended September 30, 
1998, a 21% decrease compared to $153,000 for the year ended September 30, 
1997. Basic earnings per share was $.44 for 1998 and $.58 for 1997. Diluted 
earnings per share was $.40 for 1998 and $.54 for 1997.

     As of September 30, 1998, assets totaled $48,241,000, an increase of 2% 
over the same period in 1997. Total loans decreased by $2,485,000 or 7% while 
investments increased to $10,529,000, a growth of $5,147,000 or 96%.

     Cargill also showed $42,995,000 in deposits at September 30, 1998 compared 
to $43,119,000 at September 30, 1997.

     For the year ended 1998, Cargill's return on average assets was .25% and 
the return on average equity totaled 3.7%.

   
     The institution that first expressed an interest in a possible transaction
with Cargill contacted Cargill after the Westbank Merger Agreement was executed
and announced to the public to express its dissatisfaction with the process that
had produced an agreement with Westbank while its offer was outstanding. Such
institution asserted that Cargill breached its obligations under the letter of
intent with that institution, and its attorneys sent a letter to Cargill
demanding to be reimbursed for
    

                                      -17-

   20
   
the costs and expenses it incurred in connection with such institution's
negotiations and attempted acquisition of Cargill. Cargill has retained counsel
and responded, refusing the demand. Cargill stated in its response that it had
fully satisfied its obligations under the letter of intent with the ultimately
unsuccessful institution and that Cargill believed such institution's factual
and legal claims to the contrary were without merit.
    

   
     On October 27, 1998, Cargill notified the Office of Thrift Supervision and 
the Commissioner of Banking for the State of Connecticut that Robert G. 
Eggleston, Jr. had resigned from his positions as President and Chief Executive 
Officer of Cargill Bank and Secretary of Cargill and from his seat as a 
director on both Boards, in order to pursue a professional opportunity 
elsewhere in Connecticut. Cargill has chosen its Senior Vice President-Chief 
Financial Officer, Howard Stanton III, to assume the duties of acting President 
to oversee the operations of Cargill Bank through the date of the Merger. 
Following consummation of the transaction, Westbank will select a new president 
and chief executive officer for Cargill Bank and Mr. Stanton is expected to 
return to his duties as Senior Vice President-Chief Financial Officer of 
Cargill Bank.

(1)      Reflects the assumed issuance of 360,080 shares of Westbank Common
         Stock in the merger based upon an exchange ratio of 1.3008 assuming the

(2)      The information above reflects Cargill's historic financial data at and
         for the six months ended March 31, 1998, and at and for the years ended
         September 30, 1997, 1996, and 1995.
    

   
(3)      Pro forma book value per share of Westbank Common Stock was calculated
         by dividing total pro forma combined shareholders' equity amounts as of
         the applicable date by the sum of (i) the total shares of Westbank
         Common Stock outstanding as of the applicable date and (ii) the total
         shares of Cargill Common Stock outstanding as of the applicable date,
         276,814 at March 31, 1998 and 257,227 at September 30, 1997, multiplied
         by the Exchange Ratio of 1.3008 shares of Westbank Common Stock for
         each share of Cargill Common Stock. Pro forma equivalent combined book
         value per share of Cargill Common Stock represents the pro forma
         combined book value per share of Westbank Common Stock multiplied by
         the Exchange Ratio of 1.3008, assuming that the actual average closing
         price was the $14.13 closing per share price of Westbank Common Stock
         on July 15, 1998. The Exchange Ratio is subject to adjustment based on
         the actual average closing price.
    

   
(4)      Westbank pro forma combined basic and diluted income per share
         represents historical net income available to common stockholders for
         Westbank and Cargill combined on the assumption that Westbank and
         Cargill had been combined for the periods presented on a
         pooling-of-interests basis, divided by the number of basic weighted
         average shares (for basic earnings per share) and diluted weighted
         average shares. Diluted weighted average shares includes the effect of
         potentially dilutive securities such as stock options, as applicable,
         of Westbank Common Stock which would have been issued and outstanding
         assuming the Merger had been completed at the beginning of the period
         based on an Exchange Ratio of 1.3008 shares of Westbank Common Stock
         for each share of Cargill Common Stock. Per common share amounts
         assuming dilution were computed assuming the exercise of stock options
         and repurchase of common stock with the proceeds resulting from such
         exercise using the average market price per share of Westbank Common
         Stock or Cargill Common Stock, as appropriate, for the applicable
         period. The pro forma combined income information does not reflect
         Merger costs, expense savings or revenue enhancements that may occur as
         a result of the Merger. See "Notes to Pro Forma Condensed Combined
         Financial Statements (unaudited)." Cargill equivalent pro forma
         earnings per common share amounts represent Pro Forma Combined
         Continuing Corporation amounts multiplied by an Exchange Ratio of
         1.3008 shares of Westbank Common Stock for each share of Cargill Common
         Stock, assuming that the actual average closing price was the $14.13
         closing per share price of Westbank Common Stock on July 15, 1998. The
         Exchange Ratio is subject to adjustment based on the actual average
         closing price.
    

   
(5)      Income per share and cash dividends declared per common share
         information reflects Westbank and Cargill for their years ended
         December 31 and September 30, respectively, and for the six months
         ended June 30, 1998 and March 31, 1998, respectively.
    

   
(6)      Westbank pro forma combined dividends declared per common share
         represent historical dividends paid by Westbank. Westbank, as the
         resulting corporation from the Merger will pay dividends at a rate to
         be determined by Westbank Board of Directors; it is anticipated that
         the initial dividend will be at the most recent rate paid by Westbank.
         Cargill pro forma equivalent dividends declared per common share
         represent Westbank pro forma dividends declared per common share
         multiplied by an Exchange Ratio of 1.3008, assuming that the actual
         average closing price was the $14.13 closing per share price of
         Westbank Common Stock on July 15, 1998. The Exchange Ratio is subject
         to adjustment based on the actual average closing price.
    

   
(7)      Assuming that the actual average closing price was $10.625 per share,
         the closing price per share of Westbank Common Stock on October 30,
         1998, the Exchange Ratio would be 1.4167 and the pro forma data set
         forth above would be reduced accordingly. Alternatively, if the actual
         average closing price of Westbank was less than $12.00 per share, the
         Board of Cargill could decide to terminate the Merger Agreement unless
         the Board of Westbank decided to increase the consideration to equal
         $17.00 per share in Westbank Common Stock for each share of Cargill
         Common Stock. The Exchange Ratio is subject to adjustment based on the
         actual average closing price.

                      SELECTED PRO FORMA CONDENSED COMBINED
                        FINANCIAL INFORMATION (UNAUDITED)

         The unaudited selected pro forma condensed combined financial
information set forth below gives effect to the Merger under the
pooling-of-interests accounting method. The selected pro forma condensed
combined operating data treats the Merger as if it had been consummated at the
beginning of the respective periods indicated, and the selected pro forma
condensed combined balance sheet data treats the Merger as if it had been
consummated at the dates indicated. The pro forma condensed combined per common
share data gives effect to the assumed issuance of 360,080 shares of Westbank
Common Stock based on an Exchange Ratio of 1.3008. The unaudited pro forma
historical condensed combined year-end statement of financial condition
information reflects Westbank and Cargill at their year-end reporting periods of
December 31 and September 30, respectively, and for the annual periods then
ended for the statement of operations information. Financial information for six
months ended June 30, 1998 and 1997 combine Westbank for such reporting periods
with Cargill interim results for the six months ended March 31, 1998 and 1997.
Following the Merger, the Continuing Corporation fiscal year, like that of
Westbank, will end on December 31. See "Pro Forma Condensed Combined Financial
Statements (Unaudited)."

         The selected pro forma condensed combined financial information set
forth below is presented for illustrative purposes only and is not necessarily
indicative of the operating results or financial position that would have
occurred if the Merger had been consummated at the dates assumed herein, nor is
it necessarily indicative of future operating results or financial position. The
selected pro forma condensed combined financial information does not give effect
to the anticipated merger costs, expense savings and revenue enhancement
opportunities that could result from the Merger or any other items or income or
expense which may result from the Merger. See "Pro Forma Condensed Combined
Financial Statements (Unaudited)." As a result, the pro forma combined financial
information of the continuing corporation at the Effective Time and thereafter
may be significantly different from the pro forma financial information
presented herein.

- --------------------

(1)   The information reflects Cargill's historical financial data as of or for
      the six months ended March 31, 1998 and 1997 and as of or for the years
      ended September 30, 1997, 1996, 1995.

(2)   Noninterest expense for the year ended December 31, 1996 included
      Cargill's share of a special assessment imposed on all financial
      institutions with deposits insured by SAIF of $272,000.

   
(3)   Westbank pro forma combined basic and diluted income per share represents
      historical net income available to common stockholders for Westbank and
      Cargill combined on the assumption that Westbank and Cargill had been
      combined for the periods presented on a pooling-of-interests basis,
      divided by the number of basic weighted average shares (for basic income
      per share) and diluted weighted average shares. Diluted income per share
      includes the effect of potentially dilutive securities such as stock
      options, as applicable, of Westbank Common Stock which would have been
      issued and outstanding assuming the Merger had been completed at the
      beginning of the period based on an Exchange ratio of 1.3008 shares of
      Westbank Common Stock for each share of Cargill Common Stock. Assuming 
      that the actual average closing price was $10.625 per share, the closing 
      price per share of Westbank Common Stock on October 30, 1998, the 
      Exchange Ratio would be 1.4167 and the pro forma data set forth above 
      would be reduced accordingly. Alternatively, if the actual average 
      closing price of Westbank was less than $12.00 per share, the Board of 
      Cargill could decide to terminate the Merger Agreement unless the Board 
      of Westbank decided to increase the consideration to equal $17.00 per 
      share in Westbank Common Stock for each share of Cargill Common Stock. 
      The Exchange Ratio is subject to adjustment based on the actual average 
      closing price.
    

(4)   Reflects the adoption in 1997 of SFAS No. 128, "Earnings Per Share." Prior
      periods have been restated.

(5)   With the exception of end-of-period ratios, all ratios are based on
      average daily balances. 

(6)   Selected financial ratios for the six months ended June 30, 1998 and 1997,
      are presented on an annual basis.

                     PRO FORMA CONDENSED COMBINED FINANCIAL
                             STATEMENTS (UNAUDITED)


         The pro forma condensed combined balance sheet as of June 30, 1998, and
the related pro forma condensed combined statements of income for the six months
ended June 30, 1998 and 1997, and for the years ended December 31, 1997, 1996
and 1995 give effect to the exchange of 100% of the outstanding Cargill Common
Stock for Westbank Common Stock. The pro forma information is based on the
historical consolidated financial statements, including the notes thereto, of
Westbank that are incorporated by reference into this Proxy
Statement-Prospectus. See "Information Incorporated by Reference" and "Westbank
Selected Consolidated Financial Information" and the historical consolidated
financial statements of Cargill, including the notes thereto, included elsewhere
herein. See "Index to Cargill Consolidated Financial Statements" and "Cargill
Selected Consolidated Financial Information". The unaudited pro forma historical
combined income statement information for the years presented reflects Westbank
for its year ended December 31, combined with Cargill income statement
information for its fiscal year ended September 30, immediately preceding the
applicable Westbank year end. Financial information for the six months ended
June 30, 1998 and 1997 combine Westbank for such reporting periods with Cargill
interim results for the six months ended March 31, 1998 and 1997, respectively.

         The pro forma information set forth below gives effect to the Merger
under the pooling-of-interests method of accounting. See "THE MERGER- Accounting
Treatment." The pro forma condensed combined statements of income give effect to
the Merger as if it had occurred at the beginning of each period presented. The
pro forma condensed combined balance sheets give effect to the Merger as if it
had occurred as of the balance sheet date. The pro forma combined per share data
gives effect to the assumed issuance of 360,080 shares of Westbank Common Stock,
based on an Exchange Ratio of 1.3008, which would result in 4,127,393 shares of
Westbank Common Stock outstanding following the Merger based upon June 30, 1998
pro forma information. See "Notes to Pro Forma Condensed Combined Financial
Statements (Unaudited)."

         This pro forma information may not necessarily be indicative of the
operating results or financial position that would have actually occurred if the
Merger had been consummated at the beginning of each period presented, nor is it
necessarily indicative of future operating results or financial position. The
pro forma information does not give effect to the anticipated merger costs or to
the anticipated expense savings and revenue enhancements that could result from
the Merger or any other items of income or expense which may result from the
Merger. See "Notes to Pro Forma Condensed Combined Financial Statements
(Unaudited)."

     NOTES TO PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS (UNAUDITED)

         (1) The unaudited pro forma condensed combined balance sheet was
prepared assuming that the Merger had been consummated as of June 30, 1998, and
the pooling-of-interests method had been applied in accounting for the Merger.
Pro forma condensed combined income statement information has been prepared
assuming that the Merger had been consummated as of the beginning of each period
presented. The unaudited pro forma historical combined income statement
information for the periods presented reflects Westbank's income statement
information for its fiscal year ended December 31, combined with Cargill's
income statement information for its fiscal year ended September 30, immediately
preceding the applicable Westbank year end. Financial information for the six
months ended June 30, 1998 and 1997 combine Westbank for such reporting periods
with Cargill interim results for the six months ended March 31, 1998 and 1997,
respectively.

         (2) Pro forma shares of common stock are based on the number of
Westbank shares outstanding plus 360,080 of additional shares assumed to be
issued in the Merger in exchange for outstanding Cargill Common Stock based on
an Exchange Ratio of 1.3008, assuming the Merger had been completed at the
beginning of the period.

         Westbank pro forma combined basic and diluted earnings per share
represents historical net income available to common stockholders for Westbank
and Cargill combined on the assumption that Westbank and Cargill had been
combined for the periods presented on a pooling-of-interests basis, divided by
the number of basic weighted average shares (for basic income per share) and
diluted weighted average shares. Diluted income per share includes the effect of
potentially dilutive securities such as stock options, as applicable, of
Westbank Common Stock which would have been issued and outstanding assuming the
Merger had been completed at the beginning of the period based on an Exchange
Ratio of 1.3008 shares of Westbank Common Stock for each share of Cargill Common
Stock. Per common share amounts assuming dilution were computed assuming the
exercise of stock options and repurchase by the respective companies of Common
Stock with the proceeds resulting from such exercise using the average market
price per share of Westbank Common Stock or Cargill Common Stock, as
appropriate, for the applicable period.

   
         Assuming that the actual average closing price was $10.625 per share, 
the closing price per share of the Westbank Common Stock on October 30, 1998, 
the Exchange Ratio would be 1.4167 and the pro forma earnings per share data 
set forth above would be reduced accordingly. Alternatively, if the actual 
average closing price of Westbank was less than $12.00 per share, the Board of 
Cargill could decide to terminate the Merger Agreement unless the Board of 
Westbank decided to increase the consideration to equal $17.00 per share in 
Westbank Common Stock for each share of Cargill Common Stock. The Exchange 
Ratio is subject to adjustment based upon the actual average closing price.
    
        
         To the extent cash is paid to Cargill shareholders in lieu of
fractional shares or due to dissenting shareholders, cash, common stock
outstanding and common shareholders' equity would be reduced. The respective
managements of the parties expect that the cash to be issued at the time of
surrender of certificates will not be considered significant. Accordingly, all
fractional shares of Westbank Common Stock have been included in the pro forma
share data.

         (3) The pro forma financial statements do not reflect payments for
anticipated merger costs (legal, accounting, tax, regulatory and severance) and
integration costs (conversion, promotional material, forms, etc), which are
estimated to be $375,000, net of taxes. The pro forma information also does not
reflect potential expense savings or revenue enhancements expected to be
realized subsequent to the consummation of the Merger.

         (4) The following are pro forma adjustments reflected in the "Pro Forma
Adjustments" column of the Pro Forma Condensed Combined Balance Sheet
(Unaudited). (Dollar amounts are in thousands.)

                                   THE MEETING

MATTERS TO BE DISCUSSED AT THE SPECIAL MEETING

         This Proxy Statement-Prospectus is being furnished to holders of shares
of Cargill Common Stock in connection with the solicitation of proxies from such
shareholders for use at the Special Meeting.

         At the Special Meeting or any adjournments or postponements thereof,
holders of shares of Cargill Common Stock will be asked to approve and adopt the
Merger Agreement and the consummation of the transactions contemplated thereby,
including the Merger.

         THE BOARD OF DIRECTORS OF CARGILL HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT AND RECOMMENDS THAT SHAREHOLDERS VOTE FOR APPROVAL AND ADOPTION OF THE
MERGER AGREEMENT AND THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED THEREBY,
INCLUDING THE MERGER.

RECORD DATE; STOCK ENTITLED TO VOTE; QUORUM

   
         The Cargill Board has fixed the close of business on November 5, 1998
as the record date (the "Record Date"). Only the holders of record of shares of
Cargill Common Stock at the close of business on the Record Date will be
entitled to notice of and to vote at the Special Meeting and any adjournments or
postponements thereof. On the Record Date, 289,690 shares of Cargill Common
Stock were outstanding and entitled to vote. The presence in person or by proxy
of the holders of one-third of the issued and outstanding shares of Cargill
Common Stock entitled to vote is required to constitute a quorum at the Special
Meeting. Shares of Cargill Common Stock for which proxies or ballots have been
received but with respect to which holders of shares have abstained with respect
to the approval and adoption of the Merger Agreement (whether as a broker
non-vote or otherwise) will be counted as present for purposes of determining
the presence or absence of a quorum for the transaction of business at the
Special Meeting.
    

SOLICITATION OF PROXIES

         Proxies in the form enclosed are being solicited by and on behalf of
the Cargill Board. Shareholders are requested to complete, date, sign and
promptly return the accompanying proxy card in the enclosed envelope. Shares
represented by a properly executed proxy received prior to the vote at the
Special Meeting and not revoked will be voted at the Special Meeting as directed
in the proxy. IF A PROXY IS SUBMITTED AND NO DIRECTIONS ARE GIVEN, THE PROXY
WILL BE VOTED FOR THE APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND THE
TRANSACTIONS CONTEMPLATED THEREBY.

         In addition to solicitation by use of the mails, Cargill may retain the
services of Chase Mellon Shareholder Services, a professional proxy solicitation
firm to solicit proxies at an anticipated cost of $3,500 plus reimbursement for
out-of-pocket expenses. Further, proxies may be solicited by



                                      -36-

   39



directors, officers and employees of Cargill in person or by telephone, telegram
or other means of communication. Such directors, officers and employees will not
be additionally compensated, but may be reimbursed for out-of-pocket expenses in
connection with such solicitation. Arrangements will be made with custodians,
nominees and fiduciaries for forwarding of proxy solicitation materials to
beneficial owners of Cargill Common Stock held of record by such persons, and
Cargill may reimburse such custodians, nominees and fiduciaries for reasonable
expenses incurred in connection therewith.

         The persons named as proxies by a Cargill shareholder may propose and
vote for one or more adjournments or postponements of the Special Meeting to
permit further solicitation of proxies in favor of the proposal to be considered
at the Special Meeting. A proxy voted against the Merger Agreement will not be
voted in favor of any adjournment or postponement of the Special Meeting.

         A holder of record of Cargill Common Stock may revoke a proxy by filing
an instrument of revocation with the Secretary of Cargill. Such shareholder may
also revoke a proxy by filing a duly executed proxy bearing a later date, or by
appearing at the Special Meeting in person and notifying the Secretary at the
Special Meeting. Any shareholder of record attending the Special Meeting may
vote in person whether or not a proxy has been previously given, but the mere
presence (without notifying the Secretary) of a shareholder at the Special
Meeting will not constitute revocation of a previously given proxy.

REQUIRED VOTE

   
         The affirmative vote of the holders of two-thirds (193,127 shares) of
the outstanding shares of Cargill Common Stock is required for approval of the
Merger Agreement and the transactions contemplated thereby. Abstentions and
broker non-votes will have the same effect as votes against the Merger
Agreement. Shareholders of Cargill are entitled to one vote at the Special
Meeting for each share of Cargill Common Stock held of record at the close of
business on the Record Date.
    

   
         At the close of business on the Record Date, 289,690 shares of Cargill
Common Stock were outstanding and entitled to vote. Cargill directors and
executive officers who beneficially own a total of 63,495 shares of Cargill
Common Stock, representing approximately 21.9% of the shares of Cargill Common
Stock issued and outstanding on the Record Date, have entered into agreements
(the "Cargill Shareholders' Agreements"), pursuant to which such shareholders
have agreed to certain restrictions on their respective shares of Cargill Common
Stock. Specifically, such shareholders have agreed, with respect to all
presently owned or after-acquired stock, (a) to vote such stock in favor of the
Merger and against any other acquisition transaction with a party other than
Westbank or its affiliates, and (b) generally not to sell, assign, transfer,
encumber or otherwise dispose of such stock. The Cargill Shareholders'
Agreements will remain in effect until the earlier of the consummation of the
Merger or the termination of the Merger Agreement in accordance with its terms.
Assuming that all of the shares subject to the Cargill Shareholders' Agreements
are in fact voted in favor of the Merger Agreement, the vote of holders of
approximately 129,632 additional shares of Cargill Common Stock, representing
approximately 44.7% of the shares of Cargill Common Stock issued and outstanding
on the Record Date, will be required to approve and adopt the Merger Agreement
and the transactions contemplated thereby.

SOLICITATION EXPENSES

Cargill will pay its own expenses in connection with the solicitation of
proxies.

                  BENEFICIAL OWNERSHIP OF CARGILL COMMON STOCK

         The following table sets forth certain information regarding beneficial

APPRAISAL RIGHTS AND DISSENTING SHAREHOLDERS

         Shareholders of Cargill who do not vote to approve and adopt the Merger
Agreement and who comply with the requirements of Section 262 of Title 8 of the
Delaware General Corporation Law (the "Dissenters' Rights Statute"), a copy of
which is attached to this Proxy Statement-Prospectus as Appendix D, will be
entitled to dissenters' rights. Shareholders of Westbank will not vote and have
no dissenters' rights in connection with the Merger.

         If the Merger is consummated, a shareholder of Cargill who does not
vote in favor of the approval and adoption of the Merger Agreement, and who
follows the statutory provisions of the Dissenters' Rights Statute summarized
herein, may require Cargill to pay the fair value of his or her shares of
Cargill Common Stock, determined as provided in the Dissenters' Rights Statute.

         A shareholder of Cargill who desires to pursue his or her dissenter'
rights must deliver to Cargill, BEFORE the taking of the vote on the Merger
Agreement, a written notice of intent to demand payment for his or her shares if
the Merger is effectuated. Notice of an intention to demand payment should be
addressed to the Secretary of Cargill. The shareholder must then not vote any
shares in favor of the approval and adoption of the Merger Agreement. A vote
against the approval and adoption of the Merger Agreement, whether by proxy or
in person at the Special Meeting, is not required to perfect a shareholder's
dissenters' rights, nor will a negative vote be considered a demand for payment
in and of itself without the prior delivery of the demand.

         Only a holder of shares of Cargill Common Stock on the date of making
such written demand for appraisal who continuously holds such shares throughout
the Effective Time is entitled to seek appraisal. Demand for appraisal must be
executed by or for the shareholder of record, fully and correctly, as such
shareholder's name appears on their Cargill Common Stock certificates. If
Cargill Common Stock is owned of record in a fiduciary capacity, such as by a
trustee, guardian or custodian, the demand should be made in that capacity, and
if Cargill Common Stock is owned by record by more than one person, as in a
joint tenancy or tenancy in common, the demand should be made by or for all
owners of record. An authorized agent, including one or more joint owners, may
execute the demand for appraisal for a holder of record; however, such agent
must identify the record owner or owners and expressly disclose in such demand
that the agent is acting as agent for the record owner or owners of such shares.



                                      -39-

   42
         A record holder, such as a broker who holds shares of Cargill Common
Stock as a nominee for beneficial owners, some of whom desire to demand
appraisal, must exercise appraisal rights on behalf of such beneficial owners
with respect to the shares of Cargill Common Stock held for such beneficial
owners. In such case, the written demand for appraisal should set forth the
number of shares of Cargill Common Stock covered by it. Unless a demand for
appraisal specifies a number of shares, such demand will be presumed to cover
all shares of Cargill Common Stock held in the name of such record owner.
BENEFICIAL OWNERS WHO ARE NOT RECORD OWNERS AND WHO INTEND TO EXERCISE APPRAISAL
RIGHTS SHOULD INSTRUCT THE RECORD OWNER TO COMPLY WITH THE STATUTORY
REQUIREMENTS WITH RESPECT TO THE EXERCISE OF APPRAISAL RIGHTS BEFORE THE DATE OF
THE SPECIAL MEETING.

         Within ten (10) days after the Effective Time, Westbank is required to
send notice of the effectiveness of the Merger to each shareholder of Cargill
who prior to the Effective Time complied with the requirements of Section 262.

         Within one hundred twenty (120) days after the Effective Time, Westbank
or any shareholder who has complied with the requirements of Section 262 may
file a petition in the Delaware Court of Chancery demanding a determination of
the fair value of the shares of Cargill Common Stock held by all shareholders
seeking appraisal. A dissenting shareholder must serve a copy of such a petition
on Westbank. If no petition is filed by either Westbank or a dissenting
shareholder within such one hundred twenty (120) day period, the rights of all
dissenting shareholders to appraisal shall cease. Cargill shareholders seeking
to exercise appraisal rights should not assume that Westbank will file a
petition with respect to the appraisal of the fair value of their shares or that
Westbank will initiate any negotiations with respect to the fair value of such
shares. Westbank is under no obligation to and has no present intention to take
any action in this regard. Accordingly, Westbank shareholders who wish to seek
appraisal of their shares should initiate all necessary action with respect to
the perfection of their appraisal rights within the time periods and in the
manner prescribed in Section 262. FAILURE TO FILE THE PETITION ON A TIMELY BASIS
WILL CAUSE THE SHAREHOLDER'S RIGHT TO AN APPRAISAL TO CEASE.

         Within one hundred twenty (120) days after the Effective Time, any
shareholder who has complied with the provisions of Section 262 is entitled,
upon written request, to receive from Westbank a statement setting forth the
aggregate number of shares of Cargill Common Stock with respect to which demands
for appraisal have been received by Cargill and the number of holders of such
shares. Such statement must be mailed within ten (10) days after the written
request therefor has been received by Westbank or within ten (10) days after
expiration of the time for delivery of demands for appraisal under Section 262,
whichever is later.

         The cost of the appraisal proceeding may be determined by the Delaware
Court of Chancery and assessed against the parties as the Court deems equitable
in the circumstances. Upon the application of a dissenting shareholder, the
court may order that all or a portion of the expenses incurred by any dissenting
shareholder in connection with the appraisal proceeding (including without
limitation reasonable attorneys' fees and the fees and expenses of experts) be
charged pro rata against the value of shares of Cargill Common Stock entitled to
appraisal. In the absence of such a determination or assessment, each party
bears its own expenses.


                                      -40-
   43
         Any shareholder who has fully demanded appraisal in compliance with
Section 262 will not, after the Effective Time, be entitled to receive payment
of dividends or other distributions on the Cargill Common Stock, except for
dividends or distributions payable to shareholders of record at a date prior to
the Effective Time.

         A Cargill shareholder may withdraw a demand for appraisal and accept
the terms of the Merger at any time within sixty (60) days after the Effective
Time, or thereafter may withdraw such demand with the written approval of
Westbank. In the event an appraisal proceeding is properly instituted, such
proceeding may not be dismissed as to any shareholder without the approval of
the Delaware Court of Chancery, and any such approval may be conditioned on the
terms the Delaware Court of Chancery deems just.

         IN VIEW OF THE COMPLEXITY OF THESE PROVISIONS OF DELAWARE GENERAL
CORPORATION LAW, ANY HOLDER OF THE CARGILL COMMON STOCK WHO IS CONSIDERING
EXERCISING APPRAISAL RIGHTS SHOULD CONSULT HIS OR HER LEGAL ADVISOR.

         A Cargill shareholder who exercises dissenters' rights and receives
cash will recognize gain for federal income tax purposes, the tax rate on which
will depend upon the holding period for his or her Cargill Common Stock. The
exchange of shares for cash upon the exercise of dissenters' rights could be
treated as substantially equivalent to a dividend and, therefore, taxed as
ordinary income if the recipient of cash owns or constructively owns other
shares of Westbank Common Stock. See "THE MERGER--Certain Federal Income Tax
Consequences."

                                   THE MERGER

GENERAL

         This section of the Proxy Statement-Prospectus describes the material
terms and provisions of the proposed Merger, including the principal provisions
of the Merger Agreement, and related transactions. A copy of the Merger
Agreement is attached to this Proxy Statement-Prospectus as Appendix A. All
shareholders are urged to read the Merger Agreement in its entirety.

         The Merger Agreement provides that, subject to the satisfaction or
waiver (where permissible) of certain conditions, which are described more fully
herein and therein, Cargill will be merged with and into Westbank. In connection
with the Merger, each outstanding share of Cargill Common Stock will be
converted into and become exchangeable for shares of Westbank Common Stock plus
cash in lieu of any fractional share of Westbank Common Stock (the "Exchange
Ratio"), as follows:


   
    

                                      -41-
   44
   
         1. If the Westbank Market Value is greater than or equal to $13.07,
then 1.3008 fully paid and nonassessable shares of Westbank Common Stock will be
exchanged for one (1) share of Cargill Common Stock;
    

         2. If the Westbank Market Value is less than $13.07 but greater than or
equal to $12.00, then the number of fully paid and nonassessable shares of
Westbank Common Stock (rounded to the nearest one ten-thousandth of a share) is
obtained by dividing (A) $17.00 per share by (B) the Westbank Market Value and
exchanging the resulting number with one (1) share of Cargill Common Stock; or

         3. If the Westbank Market Value is less than $12.00, then 1.4167 fully
paid and nonassessable shares of Westbank Common Stock will be exchanged for one
(1) share of Cargill Common Stock. However, if Westbank's Market Value is less
than $12.00, the Board of Directors of Cargill may elect to, but is not required
to, terminate the Merger Agreement unless Westbank increases the exchange ratio
to (A) $17.00 per share divided by (B) the Westbank Market Value.

         The Westbank Market Value is defined in the Merger Agreement as the
average of the closing prices of Westbank Common Stock on the NASDAQ National
Market System for each of the twenty (20) consecutive trading days ending on the
fifth trading day before the last required approval of a governmental entity is
obtained with respect to the transactions contemplated in the Merger Agreement,
without regard to any requisite waiting period in respect thereof, except if the
closing does not occur on or before the sixteenth day following the last
regulatory approval solely because of the non-expiration of waiting periods,
then it shall mean the date five (5) business days before the closing.

BACKGROUND OF THE MERGER

         Like many Connecticut financial institutions, Cargill monitored the
consolidation of the banking industry during the 1990s. During 1997 and the
first half of 1998, Cargill focused on improving shareholder value as an
independent institution. However, in considering long-term objectives, the
Cargill Board noted that increasing industry consolidation and changes in
government regulation of interstate banking had significantly increased
competition within Cargill's market area.

         In order to compete effectively in this environment, the Cargill Board
determined that it would be beneficial to expand the range of products and
services offered to Cargill's customers and to obtain the additional capital
resources that would enable it to do so. The Cargill Board discussed alternative
strategies to achieve these objectives, including the possibility of an
affiliation with another banking institution. The Board determined that an
affiliation, if properly structured, could not only enhance long-term
shareholder value by increasing the resources available to Cargill for expansion
of its franchise, but could also allow Cargill Bank to continue a form of
independent operation that would benefit its customers, suppliers, employees and
community. While its preference was for such a strategic alliance, the Cargill
Board recognized that it might also receive proposals, such as an offer to
acquire Cargill for cash, that would require the Board to determine whether the
interests of shareholders might be best served by a sale of Cargill.

   
    

                                      -42-
   45
         Cargill engaged O&Co. in August, 1997 for professional advice in
identifying, developing and assessing potential strategic alliances with other
organizations. With the assistance of O&Co., the Cargill Board analyzed these
alternatives. In the fall of 1997, a confidential information memorandum was
prepared by Cargill and O&Co., and a list of institutions that might be expected
to have some interest in a possible affiliation was developed. By early 1998,
O&Co. had contacted those institutions, several of whom requested a copy of the
confidential information memorandum. One such institution, first contacted in
October, 1997, requested additional information from Cargill and continued to
evaluate a possible transaction over the months that followed.

         In January, 1998, while discussions with the first institution
continued, Westbank and Cargill signed a confidentiality agreement. Cargill's
confidential information memorandum and certain additional information were
furnished to Westbank, and O&Co. discussed Cargill's price expectations with
Westbank. In February, 1998, Westbank indicated to Cargill that it was not
interested in pursuing a transaction.

         Later in February, the institution that first expressed interest sent
Cargill a non-binding letter of intent, suggesting a price per share for a
possible cash acquisition of Cargill and proposing to conduct a due diligence
review. At a meeting later that month, the Cargill Board considered that letter
of intent and rejected the price proposal as inadequate. Discussion with that
institution continued, however, and in early April, 1998 a revised letter of
intent was delivered to Cargill indicating interest in a cash acquisition at a
higher price per share than first proposed. This non-binding letter of intent
was subject to due diligence and negotiation, and it did not restrict Cargill's
consideration of other offers.

         Late in April, 1998, Westbank's financial advisor, NECA, contacted
O&Co. to determine whether Cargill would be interested in reopening discussions.
O&Co. advised Westbank that discussions with another party were underway, and
provided current Cargill financial information to Westbank's financial advisor.

         On May 1, 1998, O&Co. received a letter of intent from Westbank
indicating a proposed price for a stock transaction and requesting exclusivity
while Westbank conducted due diligence. At a May 8, 1998 meeting, the Cargill
Board decided to allow Westbank to conduct further due diligence as a means of
determining whether Westbank's interest was firm, but declined to enter into an
exclusivity agreement in light of the outstanding letter of intent with the
first institution. Following due diligence conducted in late May, Westbank
reaffirmed its interest in proceeding.

   
         At a meeting on June 1, 1998, the Cargill Board discussed and compared
the two proposals. With the assistance of its legal and financial advisers, the
Cargill Board reviewed the risks and benefits of stock versus cash acquisitions,
the difference in structure of the two proposals and an analysis of price
considerations. The Cargill Board directed O&Co. to advise the first institution
that a subsequent offer implying a significantly higher price for Cargill than
their letter of intent had been received and was under consideration, and that a
further meeting of the Cargill Board would shortly be held to consider and act
on the pending proposals, and that shareholder value was still the primary
consideration and the first institution was of course free to enhance its offer
before the Cargill Board
    

                                      -43-
   46
   
met again. The Cargill Board also authorized management and Cargill's advisors
to proceed to assess Westbank's proposal and make appropriate investigations and
analyses.
    

         The next meeting of the Cargill Board was June 12, 1998. A draft of a
Merger Agreement prepared by Westbank's counsel was distributed and the
structure and terms of the transaction proposed by Westbank were described to
the Cargill Board by Cargill's counsel. The Cargill Board also reviewed with
counsel at this meeting a letter from the first institution asserting that
Cargill's failure to complete the negotiation of the transaction proposed by
that institution would be a breach of obligations arising under the letter of
intent. Upon advice of its counsel, the Cargill Board authorized a response to
the first institution to the effect that nothing in the letter of intent
restricted the ability of the Cargill Board to receive and consider other
proposals or abrogated the duty of the Cargill Board to pursue the transaction
it believed was in the best interests of shareholders. At the direction of the
Cargill Board, this response also set a deadline for the delivery of any
enhanced offer to Cargill. No enhanced offer was subsequently received from the
first institution.

         As part of Westbank's ongoing review and consideration of strategic
alternatives, the Westbank Board regularly reviews the operational and
structural options available to Westbank to expand and strengthen its community
banking franchise and enhance long-term shareholder value, including
opportunities that may arise from time to time to acquire other banking and
thrift institutions. In response to O&Co.'s preliminary inquiry, Westbank
indicated that it would be interested in discussing further with Cargill the
prospects for a business combination involving the two companies. During May and
June 1998, Westbank and its advisers undertook further due diligence
investigations of Cargill, while Cargill and its advisers likewise undertook due
diligence investigations of Westbank. In addition, during this period,
Westbank's counsel distributed proposed forms of the Merger Agreement and
related documents, including the stock option agreement between Cargill and
Westbank (the "Stock Option Agreement"), to Cargill and its advisers, and
engaged in extensive discussions regarding the terms and provisions contained in
such documentation with Cargill's counsel.

         Separate special meetings were held of the Cargill Board on July 14,
1998 and of the Westbank Board on July 15, 1998 to consider the proposed
definitive form of the Merger Agreement and related documents. At the Cargill
Board meeting, the Cargill Board reviewed the chronology of events to date and
the results of the due diligence on Westbank, and again considered the risks and
benefits of the strategic transaction proposed by Westbank as compared to the
cash offer previously received. The Cargill Board also reviewed the final terms
of the Merger with counsel, and was advised by O&Co. that, in its opinion, and
based on facts known to O&Co. at that time, the consideration to be paid by
Westbank in the Merger was fair, from a financial point of view, to Cargill's
shareholders as of that date, and O&Co. agreed to update its opinion to that
effect immediately prior to the circulation of proxy materials for the Special
Meeting. After discussion and consideration of the best interests of Cargill's
shareholders and other constituencies, including the factors described below
under "Recommendation of the Cargill Board and Reasons for the Merger", the
Cargill Board unanimously approved the Merger Agreement and related agreements,
including the Stock Option Agreement, and authorized the signing of the Merger
Agreement and the Stock Option Agreement on behalf of Cargill.


                                      -44-
   47
         At the Westbank Board meeting, presentations were delivered by Westbank
senior management concerning the strategic rationale for the proposed
transaction and the results of Westbank's detailed due diligence investigation
of Cargill, as well as the course of the parties' negotiations on various
matters addressed by the Merger Agreement and related documents. In addition,
counsel viewed in detail with the Westbank Board the terms of the Merger
Agreement, Stock Option Agreement and related documentation. The Westbank Board
was also advised by NECA in writing that the consideration to be paid by
Westbank in the Merger was fair, from a financial point of view, to Westbank and
its shareholders. After discussion and consideration of the potential financial
and strategic benefits and risks of the proposed transaction, the Westbank Board
unanimously approved the Merger Agreement and related agreements, including the
Stock Option Agreement, and authorized Mr. Chase to sign the Merger Agreement,
the Stock Option Agreement, and the Cargill Shareholders' Agreement on behalf of
Westbank.

         On the morning of July 15, 1998, the Merger Agreement and the Stock
Option Agreement were executed on behalf of Westbank and Cargill, respectively.
The executive officers and directors of Cargill executed and delivered the
Cargill Shareholders' Agreements.

RECOMMENDATION OF THE CARGILL BOARD AND REASONS FOR THE MERGER: THE BOARD OF
DIRECTORS OF CARGILL BELIEVES THAT THE MERGER IS FAIR AND IN THE BEST INTERESTS
OF CARGILL AND ITS SHAREHOLDERS. THE BOARD OF DIRECTORS OF CARGILL UNANIMOUSLY
RECOMMENDS THAT THE CARGILL SHAREHOLDERS VOTE FOR THE APPROVAL AND ADOPTION OF
THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY.

         In reaching its determination that the Merger is in the best interests
of the Cargill shareholders, and recommending that the Cargill shareholders
approve the Merger, the Cargill Board consulted with Cargill management, as well
as its financial and legal advisers, and considered a number of factors. Without
assigning any relative or specific weights thereto, the following is a
discussion of the material factors considered by the Cargill Board in reaching
its determination:

         (a) the amount and form of the consideration offered by Westbank in
relation to the estimated value of Cargill Common Stock, the Cargill Board's
belief that, of the alternatives available, the Merger offered the greatest
opportunity for long-term value to the Cargill shareholders, and the expectation
that the Merger will be a tax-free transaction to Cargill and its shareholders
to the extent they receive Westbank Common Stock in exchange for their shares;

         (b) the market for the stock of financial institutions comparable to
Cargill and the reasonableness of the current value to Cargill shareholders of
the proposed Merger transaction relative to that market, including a comparison
of value computed as a multiple of earnings, a percentage of book value and a
premium on deposits;

         (c) the fact that the current value to Cargill shareholders of the
proposed Merger reflects a premium for Cargill's Common Stock over the prices at
which it has traded in the market during the previous year;

   
         (d) the market for Westbank Common Stock, including liquidity, the
reasonableness of current market pricing and potential price volatility;
    

                                      -45-
   48
   
    
         (e) the fact that upon consummation of the proposed Merger Cargill's
current shareholders would own approximately 10% of Westbank's common stock and
would be in a position to benefit from future growth in the value of the
combined franchises;

         (f) Westbank's business, results of operations, prospects and financial
condition and the historical and potential future value of the Westbank Common
Stock and dividends paid thereon;

         (g) the potential operating efficiencies and financial strength the
Merger would provide to the combined Cargill-Westbank organization, its
customers and the communities it serves, and the immediate and long-term effect
that it would have on such organization's ability to compete for new business;

         (h) the possible impact of the Merger on Cargill's customers and that,
following the Merger, the combined organization would be well situated to offer
Cargill's customers an expanded range of financial services;

         (i) the conditions to the Merger and the risks to Cargill if the Merger
were not consummated, including that the termination of the Merger Agreement
might result in a decline in the market price of Cargill Common Stock and might
have other adverse operational consequences for Cargill;

         (j) the fact that approval of the Merger Agreement requires the
affirmative vote of the holders of two-thirds of the shares of Cargill Common
Stock outstanding and entitled to vote and that the Cargill Board's decision to
approve the Merger Agreement would empower the shareholders as a group to decide
whether or not to accept Westbank's proposal to acquire Cargill; and

         (k) O&Co.'s opinion that, subject to certain stated assumptions, the
consideration to be paid to the Cargill shareholders in connection with the
Merger is fair, from a financial point of view, to Cargill shareholders, and
that O&Co. would be able to reconfirm its written opinion to such effect to
accompany the Proxy Statement-Prospectus.

OPINIONS OF FINANCIAL ADVISERS

OPINION OF OSTROWSKI & COMPANY, INC.

         O&Co. was retained by Cargill as its financial advisor to provide,
among other services, advice and assistance relating to the evaluation of
mergers and acquisitions pursuant to an engagement letter dated August 7, 1997
("O&Co. Engagement Letter"). Cargill selected O&Co. on the basis of its in-depth
knowledge of the bank and thrift industry, the qualifications, experience and
reputation of its personnel in the banking and investment communities, as well
as its experience in the valuation of bank and thrift institutions and their
securities in connection with mergers and acquisitions and other corporate
transactions.

         As part of the advisory services described above, the Board of
Directors of Cargill requested O&Co.'s opinion as to the fairness, from a
financial point of view, of the terms of the Merger Agreement to the holders of
Cargill Common Stock. In requesting O&Co.'s advice and opinion, Cargill's Board
of Directors did not give any special instructions to or impose any limitations
upon the scope of the investigation which O&Co. might wish to conduct to enable
it to give its opinion. On July 14, 1998, O&Co. delivered its opinion to the
Board of Directors of Cargill that, as of such date, the consideration to be
received by the holders of Cargill Common Stock was fair from a financial point
of view. On November 2, 1998, O&Co. delivered to the Board of Directors of
Cargill another written opinion confirming its opinion of July 14, 1998.
    

         THE FULL TEXT OF O&CO.'S FAIRNESS OPINION IS ATTACHED AS APPENDIX B TO
THIS PROXY STATEMENT-PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. THE
DESCRIPTION OF THE FAIRNESS OPINION SET FORTH HEREIN IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO APPENDIX B. HOLDERS OF CARGILL COMMON STOCK ARE URGED
TO READ THE OPINION IN ITS ENTIRETY FOR A DESCRIPTION OF THE PROCEDURES
FOLLOWED, ASSUMPTIONS MADE, MATTERS CONSIDERED AND QUALIFICATIONS OF THE REVIEW
UNDERTAKEN BY O&CO. IN CONNECTION THEREWITH. O&CO.'S OPINION IS DIRECTED SOLELY
TO THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE TERMS OF THE MERGER
AGREEMENT AND DOES NOT CONSTITUTE ANY RECOMMENDATION TO THE BOARD OF DIRECTORS
OF CARGILL OR TO THE HOLDERS OF CARGILL COMMON STOCK WITH RESPECT TO ANY VOTE AT
THE SPECIAL MEETING.

         In connection with providing its opinion, O&Co. examined and relied
upon, among other things: the Merger Agreement; annual reports to shareholders,
proxy statements and related audited financial statements for Cargill for each
of the three fiscal years ended September 30, 1995, 1996 and 1997; certain
unaudited interim financial reports for Cargill for the quarters ended December
31, 1997, March 31, 1998 and June 30, 1998; certain other financial information
for Cargill, including pro forma financial statements and management's estimates
relating to, among other things, earnings, asset quality, loan delinquencies and
capital; annual reports to shareholders, proxy statements and related audited
financial statements for Westbank for each of the three years ended December 31,
1995, 1996 and 1997; certain unaudited interim financial reports for Westbank
for the quarter ended March 31, 1998; certain other financial information for
Westbank, including pro forma financial statements and management's estimates
relating to, among other things, earnings, asset quality, loan delinquencies and
capital. O&Co. conducted discussions with executive management of Cargill and
Westbank concerning historical financial performance and conditions, market area
economic conditions, future business prospects and financial forecasts. O&Co.
also reviewed comparable financial, operating and market data for the banking
industry and selected peer groups; compared the terms of the Merger Agreement
with other bank and thrift merger and acquisition transactions; and considered
such additional financial and other information deemed relevant.

   50
   
         In preparing its opinion, O&Co. relied upon the accuracy, completeness
and fair presentation of all information supplied or otherwise made available to
it by, or on behalf of, Cargill and Westbank. O&Co. has not independently
verified such information or undertaken an independent evaluation or appraisal
of the assets or liabilities of Cargill or Westbank, nor was O&Co. furnished any
such evaluations or appraisals. With respect to forecasts of expected future
financial performance, O&Co. has been advised that they reflect the best
currently available estimates and judgement of executive management of Cargill
and Westbank. O&Co.'s opinion is necessarily based upon the information
available to it and the market, economic and other conditions, as they exist and
can be evaluated, as of the date of the opinion.
    

         In connection with providing its fairness opinion to the Board of
Directors of Cargill, O&Co. performed a variety of financial analyses. The
following is a summary of the material terms of such analyses but does not
purport to be a complete description of O&Co.'s analyses or presentations to the
Cargill Board of Directors. The preparation of a fairness opinion is a complex
process involving subjective judgments and does not necessarily lend itself to
partial analyses or summary description. O&Co. believes that its analyses must
be considered as a whole and that selecting portions of such analyses and the
factors considered therein, without considering all factors and analyses, could
create an incomplete view of the analyses and the processes underlying O&Co.'s
opinion.

         In performing its analyses, O&Co. made numerous assumptions with
respect to industry performance, business and economic conditions and various
other matters, many of which may be more or less favorable than actual results.
Estimates of values of companies do not purport to be appraisals or necessarily
reflect the prices at which companies or their securities may actually be sold.
No company or transaction utilized in O&Co.'s analyses was identical to Cargill
or Westbank or to the terms of the Merger Agreement. Because such estimates are
inherently subject to uncertainty, O&Co. assumes no responsibility for their
accuracy.

Stock Trading History

         O&Co. examined the average quarterly trading pricing trends for
community banks and thrifts headquartered in Connecticut, Maine, Massachusetts,
New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island and Vermont
(collectively, the "Northeast") from the first quarter 1997 through the second
quarter 1998. During that time period, the average quarterly price/earnings
ratio for Northeast community bank stocks was between 14.6 times and 20.7 times
last twelve months earnings ("LTM earnings"), with a low of 14.6 times LTM
earnings for the first quarter of 1997 and a high of 21.4 times LTM earnings for
the first quarter of 1998. The quarterly average price/earnings ratio for
Northeast community thrift stocks was between 16.8 times and 19.2 times LTM
earnings over the same time period . The lowest quarterly average multiple for
thrift stocks was 16.8 times LTM earnings for the first quarter of 1997 and the
highest was 21.7 times LTM earnings for the third quarter of 1997.

   
         The quarterly average of Northeast community bank stock prices measured
against book value for the same time period was between one hundred and seventy
eight percent (178%) and two hundred and forty nine percent (249%) of book
value, with a low of one hundred seventy eight percent (178%) for the first
quarter 1997 and a high of two hundred sixty four percent (264%) for
    


                                      -48-
   51
   
the first quarter of 1998. The quarterly average for Northeast community thrift
stocks over the same time period was between one hundred thirty four percent
(134%) and one hundred and eighty one percent (181%) of book value. The lowest
value was one hundred and thirty four percent (134%) for the first quarter of
1997; and the highest value of one hundred ninety five percent (195%) was for
the first quarter of 1998.
    

         During the same time period, Westbank Common Stock, which is listed on
the NASDAQ National Market System, generally traded in the $10.00 to $15.00
range, or 13.6 to 15.1 times LTM earnings and 161% to 206% of book value. In the
early part of the period through the second quarter 1997, Westbank's stock
traded at the low end of the range, at prices at or below $10.00. Through the
first quarter 1998 , Westbank Common Stock rose steadily from the $10.00 range
to a high of $16.75. From early April 1998, the stock declined, generally
trading between $16.00 and $14.13. On July 13, 1998 Westbank Common Stock closed
at $14.13.

         Cargill stock is relatively closely held, with the Board of Directors
holding approximately 32% of the outstanding shares of Cargill Common Stock.
Cargill Common Stock is not listed on any exchange and trades infrequently.
Therefore, meaningful trading market data for Cargill does not exist.

Contribution Analysis

         O&Co. prepared a contribution analysis showing the percentage
contributed by Cargill to the combined company on a pro forma basis of assets,
deposits and equity at March 31, 1998. This analysis showed that Cargill
Shareholders would contribute 12.9 % of pro forma consolidated assets, 13.4% of
pro forma consolidated deposits and 11.6% of pro forma equity. Net income
contributions were considered based upon quarter ended March 31, 1998 results
annualized for Westbank, and six months ended March 31, 1998 results for Cargill
on an annualized basis. Cargill contributed 6.4% to consolidated pro forma net
income. Cargill Shareholders will receive approximately 10.5% of the pro forma
ownership of the combined company assuming an exchange ratio of 1.3008.

Comparable Company Analysis

         O&Co. compared the financial condition and operating performance of
Cargill with a peer group of NASDAQ and exchange-listed financial institutions
headquartered in the Northeast with assets less than $105 million. Cargill
reported a return on average assets of 0.49%, and a return on average equity of
6.91%, based on six months ended March 31, 1998 results annualized, and an
equity to assets ratio of 7.06% as of March 31, 1998. Cargill's annualized
results for the six months ended March 31, 1998 were utilized because they were
considered to more appropriately reflect Cargill's recurring earnings potential.
Based on trailing twelve months earnings per share as of March 31, 1998, the
peer group's average return on average assets was 0 .65%; average return on
average equity was 5.91%, and its average equity to assets ratio was 12.24% as
of March 31, 1998. Cargill reported a somewhat lower return on assets than the
peer group and an above average return on equity as a result of its lower equity
to asset ratio.

   
    

                                      -49-
   52
   
         O&Co. compared the financial condition and operating performance of
Westbank with a peer group of NASDAQ and exchange-listed banks and thrifts
headquartered in the Northeast with assets between $250 million and $350
million. Westbank reported a return on average assets of 1.12% and a return on
average equity of 15.20%, based on March 31, 1998 trailing twelve months
earnings per share, and an equity to assets ratio of 8.00% as of March 31, 1998.
The peer group had an average return on average assets of 1.00%, an average
return on average equity of 10.16% and an average equity to assets ratio of
10.17%. Westbank reported operating performance above the peer group and a lower
equity to assets ratio.
    

         O&Co. also compared the trading performance of Westbank with this peer
group. At July 13, 1998, Westbank's Common Stock price closed at $14.13, or 15.2
times earnings for the twelve months ended March 31, 1998, and 208% of reported
March 31, 1998 book value, compared to the peer group averages for these same
measures at closing on July 13, 1998 of 20.1 times and 193%, respectively.
Westbank's trading performance was below its peers on an earnings multiple basis
but above its peer on a book value basis.

Analysis of Selected Merger Transactions

         O&Co. reviewed certain financial data, as of the date of the
announcement, for acquisitions of commercial banks and thrifts in the Northeast
announced between January 1997 and June 1998. O&Co. also reviewed acquisitions
of commercial banks and thrifts in Connecticut between January 1997 and June
1998. O&Co. calculated the average multiple of price to target's earnings for
trailing 12 months, the average percentage of price to book value and the
average premium (price in excess of reported equity) as a percentage of
deposits, on a quarterly basis beginning January 1, 1997 through June 30, 1998.
For transactions announced in the second quarter of 1998, the calculations
resulted in the following comparisons: (i) average price as a multiple to
earnings for Northeast banks of 22.9 times, Northeast thrifts of 27.5 times, and
Connecticut transactions of 25.1 times, compared with the value of the proposed
transaction of 27.0 times Cargill's 1998 earnings estimate; (ii) average price
as a percentage of book value for Northeast banks of 246%, Northeast thrifts of
260%, and Connecticut transactions of 257%, compared with the value of the
proposed transaction of 186% of Cargill's fully converted shareholders' equity;
(iii) average premium as a percentage of deposits for Northeast banks of 21.1%,
Northeast thrifts of 23.7%, and Connecticut transactions of 18.8%, compared with
the value of the proposed transaction of a premium of 6.7% of Cargill's
deposits.

Impact Analysis

         O&Co. analyzed the changes in the amount of earnings per share and book
value represented by the issuance of 1.3008 shares of Westbank Common Stock for
each share of Cargill Common Stock on a fully-converted per share equivalent
basis. The analysis was based upon reported March 31, 1998 balance sheet data
for Cargill and Westbank and three months ended March 31, 1998 operating results
annualized for Westbank and six months ended March 31, 1998 operating results
annualized for Cargill.

   
         O&Co. also analyzed certain per share values for Cargill Common Stock,
on a fully converted basis, on an independent basis as well as the equivalent
values based on the 1.3008 per share exchange ratio, as proposed in the Merger,
and the July 13, 1998 closing price for Westbank
    


                                      -50-
   53
   
Common Stock of $14.13. The estimated 1998 earnings per equivalent share of
Cargill Common Stock was $1.09, which was 60% greater than Cargill's estimated
1998 earnings per share on an independent basis. Book value per equivalent share
of Cargill Common Stock as of March 31, 1998, was $8.93, 9% less than Cargill's
book value per share as of the same date on an independent basis. The annual
cash dividends per equivalent share of Cargill Common Stock was $.52. Cargill
currently does not pay cash dividends. The market value per equivalent share of
Cargill Common Stock was $18.37 based upon the July 13, 1998 closing price of
$14.13 for Westbank Common Stock.
    

Discounted Cash Flow Analysis

         O&Co. performed an analysis which estimated the future cash flows to
Cargill shareholders over a two year period under various circumstances,
assuming Cargill performed in accordance with the earnings forecasts of its
management. To approximate the terminal value of Cargill Common Stock at the end
of the two-year period, O&Co. applied price to earnings multiples ranging from
20.0 times to 30.0 times, which resulted in values that equated to percentages
of book value ranging from 151% to 227%. The terminal values were then
discounted to present values using discount rates ranging from 10.0% to 17.5%,
chosen to reflect assumptions regarding rates of return and risk premiums
required by holders or prospective holders of Cargill Common Stock. This
analysis indicated a range of present values per share of $11.08 to $20.25.

Remaining Independent Scenario

         O&Co. discussed with Cargill's management and Board of Directors the
various expenses associated with remaining as an independent company while
achieving acceptable shareholder returns. In order to survive independently in a
highly competitive market, Cargill would have to broaden its product and service
offerings to attract and retain customers. This strategy would require a
near-term investment in Cargill through the attraction and retention of
additional qualified personnel and a substantial investment in technology.
Moreover, the potential benefit of new products and services is long-term with
no certainty as to the degree of success and Cargill's operating performance
would likely suffer in the short-term with adverse implications to shareholder
value.

         CARGILL HAS AGREED TO PAY O&CO. FOR ADVISORY SERVICES AND, IN
CONNECTION WITH THE MERGER, AN ADVISORY FEE EQUAL TO 1.5% OF THE AGGREGATE VALUE
OF THE CONSIDERATION TO BE RECEIVED BY CARGILL SHAREHOLDERS, OR APPROXIMATELY
$103,000. CARGILL HAS MADE PAYMENTS TO O&CO. TOTALING $60,000 AS OF THE MAILING
OF THE PROXY STATEMENT-PROSPECTUS. PURSUANT TO THE O&CO. ENGAGEMENT LETTER,
CARGILL HAS ALSO AGREED TO REIMBURSE O&CO. FOR ITS REASONABLE OUT-OF-POCKET
EXPENSES, INCLUDING LEGAL FEES, INCURRED IN CONNECTION WITH ITS ENGAGEMENT AND
TO INDEMNIFY O&CO. AND ITS AFFILIATES AND THEIR RESPECTIVE DIRECTORS, OFFICERS,
EMPLOYEES, AGENTS AND CONTROLLING PERSONS AGAINST CERTAIN EXPENSES AND
LIABILITIES.

OPINION OF NORTHEAST CAPITAL & ADVISORY, INC.
    

   
         The obligation of Westbank to complete the Merger is subject to the
condition that Westbank receive a written opinion from NECA on or before the
date of the Agreement and updated in writing as of a date within five days of
the mailing of this Proxy Statement-Prospectus. The November 2, 1998 fairness
opinion from NECA, which is attached hereto as Appendix C, states that as of the
date of such opinion, the consideration terms set forth in the Agreement are
fair to Westbank shareholders. The opinion does not address whether the Merger
will be fair to Westbank stockholders as of the Effective Time based on any
hypothetical Westbank Trading Price.
    

         NECA was selected by Westbank to act as its financial advisor in
connection with the Merger based upon NECA's qualifications, experience, and
reputation, as well as upon NECA's prior investment banking relationship and
general familiarity with Westbank. NECA, as part of its investment banking
business, is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements and valuations for estate, corporate and
other purposes.

   
         In connection with NECA's engagement, Westbank requested that NECA
evaluate the fairness, from a financial point of view, to the shareholders of
Westbank of the Exchange Ratio in the proposed Merger. At the July 15, 1998
meeting of the Westbank Board, NECA delivered a written opinion to the Westbank
Board that, as of such date, the proposed Exchange Ratio in the Merger was fair
from a financial point of view to the Westbank stockholders (other than Cargill
and its affiliates). On November 2, 1998, NECA delivered to the Westbank Board
another written opinion confirming its opinion of July 15, 1998.
    

         The full text of the opinion of NECA dated as of the date of this Proxy
Statement-Prospectus, which sets forth, among other things, assumptions made,
procedures followed, matters considered and limits on the review undertaken by
NECA, is attached as Appendix C to this Proxy Statement-Prospectus. Holders of
Westbank Common Stock are urged to read the opinion in its entirety. NECA's
opinion is addressed to the Westbank Board and does not constitute a
recommendation to any Westbank Shareholder. The summary set forth in this Proxy
Statement-Prospectus of the opinion of NECA is qualified in its entirety by
reference to the full text of the opinion attached as Appendix C to this Proxy
Statement-Prospectus.

   
         In connection with this opinion, NECA reviewed, among other things, the
Merger Agreement; the Annual Reports of Cargill for the three years ended
September 30, 1997; the Annual Report on Form 10-K of Westbank for the year
ending December 31, 1997; certain Quarterly Reports of Cargill and Westbank;
certain unaudited interim reports and certain press releases to the respective
shareholders of Westbank and Cargill; and financial information concerning the
business and operations of Westbank and Cargill furnished to NECA by their
respective managements. NECA also conducted discussions with members of the
senior managements of Westbank and Cargill regarding the past and current
business operations, regulatory relationships, financial condition and future
prospects of their respective companies. In addition, NECA reviewed the reported
price and trading activity of Cargill's and Westbank's
    

                                      -52-
   55
   
Common Stock; compared certain financial information for Westbank and Cargill
with certain financial and stock market information for certain other companies,
the securities of which are publicly traded; reviewed the financial terms of
certain recent business combinations in the commercial banking environment in
particular; and performed such other studies and analyses as NECA considered
appropriate.
    

   
         In conducting its review and arriving at its opinion, NECA assumed and
relied upon the accuracy and completeness of all financial and other information
supplied or otherwise made available to it and did not assume any responsibility
for any independent verification of such information. With respect to financial
forecasts (including projected cost savings, revenue enhancements, operating
synergies and other possible operating and financial benefits), NECA assumed and
relied upon the senior management of Westbank and Cargill as to the
reasonableness and achievability of the financial and operating forecasts and
that they were reasonably prepared on bases reflecting the best currently
available estimates and judgments of management of Westbank and Cargill as to
the future financial performance of Westbank and Cargill, respectively, and NECA
assumed that such forecasts and projections would be realized in the amounts and
at the times contemplated thereby. NECA assumes no responsibility for and
expresses no view as to such forecasts and projections or the assumptions on
which they are based. NECA also assumed the aggregate allowance for loan losses
for Cargill and Westbank were adequate to cover such losses. NECA did not make
or obtain any evaluations or appraisals of the property of Cargill or Westbank.
NECA did, however, examine certain individual credit files of Cargill and
independently produced projections and operating forecasts to assure themselves
that the assumptions generated by Cargill and Westbank senior management did not
materially and adversely alter the adequacy of the financial consideration
offered by Westbank from a financial point of view.
    

         As a matter of policy, neither Westbank nor Cargill publicly disclose
internal management forecasts, projections or estimates of the type furnished to
NECA in connection with their analysis of the Merger, and such forecasts,
projections, and estimates were not prepared with a view towards public
disclosure. These forecasts, projections, and estimates were based on numerous
variables and assumptions which are inherently uncertain and which may not be
within the control of management, including without limitation, general
economic, regulatory and competitive positions. Accordingly, actual results
could vary materially from those set forth in such forecasts, projections, and
estimates.

         NECA's opinions are predicated on the Merger receiving the tax,
regulatory and accounting treatment contemplated by the Merger Agreement,
including that the Merger would be recorded as a "pooling of interests" in
accordance with generally accepted accounting principles ("GAAP"). NECA's
opinions were necessarily based upon economic, market and other conditions as in
effect on, and the information made available to it as of, the date of such
opinions. No limitations were imposed by Westbank on the scope of NECA's
investigation or on the procedures followed by NECA in rendering its opinion.

   
    

                                      -53-
   56
   
         In connection with rendering its opinion to the Westbank Board, NECA
performed a variety of financial analyses in support of its opinion which are
summarized below. The summary set forth below does not purport to be a complete
description of the analyses performed by NECA in this regard, although it
describes all material analyses performed by NECA. The preparation of a fairness
opinion involves various determinations as to the most appropriate and relevant
methods of financial analysis and the application of these methods to the
particular circumstances, and therefore such an opinion is not readily
susceptible to a partial analysis or summary description. Accordingly,
notwithstanding the separate factors summarized below, NECA believes that its
analyses must be considered in their entirety and that selecting portions of its
analyses and the factors considered by it, without consideration of all factors
and analyses, could create a misleading or incorrect view of the analyses and
the processes underlying NECA's opinions.
    

NECA arrived at its opinion based on the results of all the analyses it
undertook assessed as a whole, and it did not draw conclusions from or with
regard to any one method of analysis. The fact that any specific analysis has
been referred to in the summary below is not meant to indicate that such
analysis was given more weight than any other analysis. With respect to the
comparable company analysis, and bank merger and acquisition transaction
analyses summarized below, no public company utilized as a comparison is
identical to Westbank or Cargill, no transaction is identical in nature or
rationale to the contemplated transaction between Westbank and Cargill, and such
analyses necessarily involve complex considerations and judgments concerning the
differences in financial and operating characteristics of the companies and
other factors that could affect the acquisition or public trading values of the
companies concerned. Estimates of values of companies or assets do not purport
to be appraisals or necessarily reflect the prices at which companies or their
securities actually may be sold.

         NECA's opinions are directed to the Westbank Board and address only the
Exchange Ratio. They do not address the underlying business decision to proceed
with the Merger and do not constitute, nor should they be construed as, a
recommendation to any Westbank Stockholder on any other matter in connection
therewith.

         In performing its analyses, NECA made numerous assumptions with respect
to industry performance, general business and economic conditions and other
matters, all of which are beyond the control of NECA, Westbank and Cargill. The
analyses performed by NECA are not necessarily indicative of actual values or
actual future results, which may be significantly more or less favorable than
suggested by such analyses. In addition, the analyses do not purport to be
appraisals or to reflect the prices at which any securities of Westbank or
Cargill may trade at the present time or at any time in the future. Such
analyses were prepared solely as part of NECA's analysis of the fairness of the
Exchange Ratio to the Westbank Stockholders (other than Cargill and its
affiliates) and were provided to the Westbank Board in connection with the
delivery of NECA's opinions.

   
         The following is a summary of the material analyses presented by NECA
to the Westbank Board in connection with its July 15, 1998 opinion, which, as
indicated above, was confirmed as of November 2, 1998.
    

   
    

                                      -54-
   57
         (a) Offer Valuation. NECA reviewed the terms of the proposed
transaction, including the Exchange Ratio and the aggregate transaction value.
NECA reviewed the implied value of the consideration offered based upon the
closing share price of Westbank Common Stock on July 14, 1998 (the last trading
day prior to the announcement of the Merger), which indicated that the implied
value of the consideration offered in the Westbank proposal was approximately
$18.37 per share of Cargill Common Stock, representing a total transaction value
of approximately $5.9 million based upon 341,350 fully diluted shares of Cargill
Common Stock outstanding, 64,536 of which are options at an average exercise
price of $5.4657, and which options' value is considered net of this exercise
price to compute the total transaction value. Based on the aggregate
consideration offered using the $18.37 proposed transaction price for Cargill
Common Stock, NECA calculated the multiples of proposed offer value to tangible
book value per share, proposed offer value to implied core deposit premium and
proposed offer value to Cargill's trailing 12 month's earnings in the
contemplated transaction. This analysis resulted in the following multiples: a
proposed offer value to fully diluted tangible book value per share multiple of
1.57x; a proposed offer value to implied core deposit premium multiple of 7.18%;
and a proposed offer value to Cargill's trailing 12 months earnings of 31.99x.

         (b) Pro Forma Merger Analysis. Based on projections provided by
Westbank and Cargill, NECA analyzed certain pro forma effects resulting from the
Merger. This analysis indicated that the transaction would be dilutive to
current earnings per share ("EPS") of Westbank Common Stock at the time of the
Merger (before the one-time charge associated with the Merger), and neutral to
slightly accretive in the year following the Merger.

         (c) Contribution Analysis. NECA prepared a contribution analysis
showing the percentage contributed by Westbank to the combined company on a pro
forma basis of assets, deposits and equity at March 31, 1998. This analysis
showed that Westbank would contribute 87.1% of pro forma consolidated assets,
86.6% of pro forma consolidated deposits and 88.7% of pro forma consolidated
equity. Net income contributions were considered based upon quarter ended March
31, 1998 results. Westbank contributed 91.6% to consolidated pro forma net
income. Westbank Shareholders will receive approximately 89.6% of the pro forma
ownership of the combined company assuming an exchange ratio of 1.3008.

         (d) Discounted Dividend Stream Analysis. Using a discounted dividend
stream analysis, NECA estimated the present value of the future streams of
after-tax cash flows that Cargill could produce on a stand-alone basis from 1998
through 2002 and distribute to stockholders ("Dividendable Net Income"). In this
analysis, NECA assumed, among other things, that Cargill performed in accordance
with the earnings forecasts provided to NECA by Cargill's senior management and,
assuming a 5% annual growth rate on deposits and an 8% to 12% annual growth rate
on loans, projected the after-tax cash flows. NECA calculated the sum of (i) the
terminal values per share of Cargill Common Stock based on an assumed multiple
of Cargill's projected 2002 net income of 18.6x plus (ii) the projected
1998-2002 five-year after-tax cash flows per share, in each case, discounted to
present values at an assumed discount rate of 15.0%. This discounted dividend
stream analysis indicated a reference range of $18.23 to $23.63 per share of
Cargill Common Stock.

   
    

                                      -55-
   58
   
         (e) Analysis of Selected Acquisition Transactions. NECA reviewed
publicly available information regarding transactions involving the acquisition
of banks and thrifts in New England with total assets under $150 million which
had occurred since January 1, 1997. Based upon a review of these selected
acquisition transactions, NECA determined that the relevant range of tangible
book multiples were 170.7% to 182.1%, the relevant range of trailing 12 months
EPS multiples were 18.63x to 18.65x and the relevant range of tangible book
premium to core deposits multiple were 9.74% to 10.59%. NECA then calculated the
implied multiples for Cargill based on the proposed offer value, resulting in a
tangible book multiple of 157.2%, a trailing 12 months EPS multiple of 31.99x
(19.22x if compared to annualized March 1998 earnings) and a tangible book
premium to core deposits multiple of 7.18%. This analysis of selected
acquisition transactions indicated a reference range of $19.95 to $22.11 per
share of Cargill Common Stock.
    

         No company or transaction used in the above analysis as a comparison is
identical to Westbank, Cargill or the contemplated transaction. Accordingly, an
analysis of the results of the foregoing necessarily involves complex
considerations and judgments concerning differences in financial and operating
characteristics of the companies and other factors that could affect the value
of the companies to which they are being compared. Mathematical analysis (such
as determining the mean or median) is not, in itself, a meaningful method of
using comparable company data.

         (f) Comparable Companies Analysis. NECA reviewed and compared certain
financial information, ratios, and public market multiples relating to Westbank
to the publicly available corresponding data for a selected group of eleven
banks in New York and New England whose assets are $200 million to $500 million
with similar loan portfolio composition to Westbank which NECA deemed to be
relevant (collectively, the "Westbank Selected Companies").

         Based on a review of such information for the Westbank Selected
Companies, NECA determined: (i) the relevant median for trailing 12 months EPS
multiple for the Westbank Selected Companies to be 19.75x, compared to 16.05x
for Westbank; (ii) the median tangible book value multiple for the Westbank
Selected Companies to be 224.6%, compared to 208.3% for Westbank; (iii) the
median market capitalization to deposits multiple for Westbank Selected
Companies to be 25.14%, compared to 19.05% for Westbank. This analysis of
selected measures indicated that Westbank's market capitalization appeared at a
discount relative to its peer group.

         (g) Trading Activity. NECA analyzed the trading activity of Westbank
and Cargill Common Stock based on weekly data for the period between July 21,
1997 and July 14, 1998. Westbank Common Stock traded at a range of $9.38 to
$17.25 during this period, with an average volume of 27,241 shares per week.
Cargill Common Stock was extremely thinly traded. The last observable
transaction before announcement of the proposed Merger was on June 6, 1998 at a
price of $11.50 per share of Cargill Common Stock.

   
    

                                      -56-
   59
   
         In connection with its opinion dated November 2, 1998, NECA performed
procedures to update, as necessary, certain of the analyses described above and
reviewed the assumptions on which such analyses described above were based and
the factors considered in connection therewith. NECA did not perform any
analyses in addition to those described in updating its July 15, 1998 opinion.
NECA has been retained by the Westbank Board to act as financial advisor to
Westbank with respect to the Merger and will receive a fee for its services.
NECA has in the past six years provided financial advisory, investment banking
and other services to Westbank and has received customary fees for the rendering
of such services. In addition, in the ordinary course of its securities
business, NECA or any of its affiliates may trade debt and/or equity securities
of Westbank and Cargill for its own account and NECA, therefore, may from time
to time hold a long or short position in such securities.
    

         Westbank and NECA executed an engagement agreement dated May 22, 1998
providing for the retention by Westbank of NECA as its financial advisor. In
connection with the Cargill transaction, NECA is expected to receive a success
fee of $80,000 upon obtaining all necessary governmental and regulatory
approvals, which includes any fees due for a fairness opinion. Upon request by
Westbank, NECA rendered a fairness opinion to the Board of Directors of Westbank
for which NECA received a fee of $25,000, which is not subject to consummation
of the Merger. In addition, the engagement agreement provides that Westbank
reimburse NECA for all reasonable out-of-pocket expenses. Westbank has also
agreed to indemnify NECA and its officers, directors, agents and employees
against any losses, claims, damages, liabilities or expenses related to such
engagement.

EFFECTIVE TIME OF THE MERGER; CLOSING DATE

         If the Merger Agreement is approved and adopted by the requisite vote
of Cargill shareholders, and the other conditions to the Merger are satisfied or
(where permissible) waived, the Merger will be consummated and become effective
upon the date (or a subsequent date not later than the opening of business the
next business day) when the Merger becomes effective as set forth in the
Articles of Merger as filed with the Secretary of the Commonwealth of
Massachusetts (the "Effective Time").

CONVERSION OF SHARES OF CARGILL COMMON STOCK PURSUANT TO THE MERGER

   
          Each certificate which immediately prior to the Effective Time 
represented outstanding shares of Cargill Common Stock shall on and after the
Effective Time be deemed for all purposes to represent the Merger Consideration
into which the shares of Cargill Common Stock represented by such certificate
shall have been converted. The "Merger Consideration" is defined as the shares 
of Westbank Common Stock that holders of Cargill Common Stock are entitled to 
receive under the Merger Agreement. 
    

   
         At the Effective Time, automatically and without any action on the part
of the holder thereof, each share of Cargill Common Stock issued and outstanding
immediately prior to the Effective Time (other than (i) shares held by
dissenting shareholders ("Dissenting Shares"), (ii) shares held directly or
indirectly by Westbank, other than shares held in a fiduciary capacity, and
    


                                      -57-
   60
   
(iii) any shares held as treasury stock by Cargill) will become and be converted
into shares of Westbank Common Stock.
    

   
         The "Westbank Market Value" is defined as the average of the closing 
prices of shares of Westbank Common Stock as reported on the NASDAQ National 
Market System for the twenty consecutive trading days ending on the fifth 
business day prior to the Effective Date. If the Westbank Market Value is less 
than $12.00 per share, Cargill will have the right to terminate the Merger 
Agreement, unless Westbank elects, in its sole discretion, to increase the 
Merger Consideration to $17.00 worth of Westbank Common Stock for each share of 
Cargill Common Stock.

         Assuming the Merger is approved by the holders of Cargill Common 
Stock, the Cargill Board could elect to consummate the Merger without 
resoliciting Cargill shareholders if the Westbank Market Value were less than 
$12.00 and Westbank did not elect to increase the Merger Consideration to 
$17.00 worth of Westbank Common Stock, even though the calculated value of the 
shares of Westbank Common Stock (based on the Westbank Market Value) to be 
exchanged for each share of Cargill Common Stock would be less than $17.00. In 
such a situation, in considering whether to consummate the Merger without the 
resolicitation of Cargill shareholders, the Cargill Board would take into 
account, consistent with its fiduciary duties, all relevant facts and 
circumstances that exist at such time, including, without limitation, the 
advice of its financial advisers and legal counsel. The O&Co. fairness opinion 
included with this Proxy Statement-Prospectus has been delivered and speaks as 
of a date within five days of the date of this Proxy Statement-Prospectus. 
Shareholder approval of the Merger Agreement and each of the transactions 
contemplated thereby confers upon the Cargill Board the power, consistent with 
its fiduciary duties, to elect to consummate the Merger notwithstanding that 
the Westbank Market Value may be less than $12.00 and Westbank has not elected 
to increase the Merger Consideration to $17.00 worth of Westbank Common Stock. 
Under such circumstances, Cargill's shareholders would assume 100% of the 
market risk associated with the price of Westbank Common Stock. See "THE 
MERGER-Conditions to Consummation of the Merger" below.
    
       
         As of the Effective Time, each share of Cargill Common Stock held
directly or indirectly by Westbank, other than shares held in a fiduciary
capacity, and shares held by Cargill as treasury stock will be canceled, retired
and cease to exist, and no payment shall be made with respect thereto.

CERTIFICATE EXCHANGE PROCEDURES

         Certificates which represent shares of Cargill Common Stock that are
outstanding immediately prior to the Effective Time and are converted into the
Merger Consideration (the "Certificates"), shall, after the Effective Time, be
deemed to represent the Merger Consideration into which such shares have been
converted and shall be exchangeable by the holders thereof for new certificates
representing the shares of Westbank Common Stock into which such shares have
been converted.

   
    

                                      -58-
   61
   
         In lieu of the issuance of fractional shares of Westbank Common Stock,
a payment in cash, without interest, will be made to the holders of Cargill
Common Stock in respect of any fractional share that would otherwise be
issuable. The payment in cash shall be equal to the product of the fractional
share multiplied by the Westbank Market Value Price (rounded up to the nearest
cent).
    

   
         Upon surrender of a Certificate, together with a duly executed letter
of transmittal and any other required documents, the holder of such Certificate
shall be entitled to receive, in exchange therefor, as soon as practicable, a
certificate for the number of shares of Westbank Common Stock and/or a check for
the cash amount to which such holder is entitled, and such Certificate shall be
canceled.
    

         In the event any Certificate shall have been lost, stolen or destroyed,
upon receipt of appropriate evidence as to such loss, theft or destruction and
to the ownership of such Certificate by the person claiming such Certificate to
be lost, stolen or destroyed, and the receipt by Westbank of appropriate and
customary indemnification, Westbank will deliver in exchange for such lost,
stolen or destroyed Certificate the Merger Consideration and any fractional
share payment.

   
         If any Merger Consideration is to be issued in a name other than that
in which the Certificate surrendered in exchange therefor is registered, it
shall be a condition of the issuance thereof that the Certificate so surrendered
shall be properly endorsed (or accompanied by an appropriate instrument of
transfer) and otherwise in proper form for transfer and that the person
requesting such exchange shall pay to the exchange agent in advance any transfer
or other taxes required by reason of the delivery of the Merger Consideration.
    

NOTE:    HOLDERS OF CARGILL COMMON STOCK SHOULD NOT SURRENDER THEIR CERTIFICATES
         UNTIL THEY RECEIVE WRITTEN INSTRUCTIONS FROM THE EXCHANGE AGENT.

         Pursuant to the Merger Agreement, Cargill has agreed that, except with
the written consent of Westbank, prior to the Effective Time, it will conduct

convertible into shares of such stock; except that Cargill may issue shares of
Cargill Common Stock or permit treasury shares to become outstanding to satisfy
    

                                      -59-

presently outstanding options under and in accordance with the terms of the
Cargill Stock Option Plans;

                  (p) take any action that would result in the representations

         Cargill has also agreed that, except as may be specifically required or
permitted pursuant to the Merger Agreement or specifically described therein or
in the accompanying disclosure schedule, it shall during the period from the
date of the Merger Agreement to the Effective Time, except with the written
consent of Westbank, operate its business, and will cause its subsidiary,
Cargill Bank to operate the businesses, only in the usual, regular and ordinary
course of business; use reasonable efforts to preserve intact its business
organization and assets and maintain its rights and franchises; and take no
action which would:


   
    

                                      -61-
   64

   
                  (i) materially adversely affect the ability of Westbank or
         Cargill to obtain any necessary approvals of governmental authorities
         required for the transactions contemplated in the Merger Agreement or
         materially increase the period of time necessary to obtain such
         approvals, or
    

                  (ii) materially adversely affect its ability to perform its
         covenants and agreements under the Merger Agreement. Cargill will
         cooperate and take all reasonable actions within its control to cause
         the Merger to qualify for "pooling of interests" accounting treatment
         and as a reorganization within the meaning of Section 368(a) of the
         Internal Revenue Code and to contest any applications filed or to be
         filed by other entities to acquire control of or greater than 5%
         interest in Cargill.

         Cargill and Westbank have each also agreed that, except as may be
specifically required or permitted pursuant to the Merger Agreement or
specifically described therein or in the accompanying disclosure schedule, each
will:

                  (a) subject to any restrictions under applicable law or
regulation, promptly notify the other of any emergency or other change in the
normal course of its or its subsidiaries' businesses or in the operation of its
or its subsidiaries' properties and of any governmental complaints,
investigations or hearings (or communications indicating that the same may be
contemplated) if such emergency, change, complaint, investigation or hearing
would be material to its or its subsidiaries' assets, properties, liabilities,
business, results of operations, condition (financial or otherwise) or
prospects; and

                  (b) file all reports, applications and other documents
required to be filed by it with the Board of Governors of the Federal Reserve
System, the FDIC, the Massachusetts Board of Bank Incorporation (the "MBBI"),
the Connecticut Banking Commissioner and any other applicable governmental
agency or authority between the date of the Merger Agreement and the Effective
Time and shall furnish to the other copies of all such reports promptly after
the same are filed.

TERMINATION

   
         The Merger Agreement is subject to termination (i) by mutual agreement
of the parties, (ii) if the Merger has not been consummated on or before March
31, 1999, (iii) by either party if any required regulatory approval or the
approval of the shareholders of Cargill is not obtained or if consummation of
the transactions contemplated by the Merger Agreement is enjoined or otherwise
prohibited, (iv) by either party for a material breach of any representation,
warranty or covenant or other agreement contained in the Merger Agreement by the
other party, which breach is not cured after 30 days written notice thereof is
given to the party committing such breach, and (v) by Cargill if the Westbank
Market Value is less than $12.00 per share, subject to Westbank's right to elect
to increase the number of shares of Westbank Common Stock issuable in the Merger
to $17.00 worth of Westbank Common Stock for each share of Cargill Common Stock.
    

         If either party terminates the Merger Agreement for reasons other than
as a result of a nonwillful breach or gross negligence of the other party,
neither party shall have any further liability under the Merger Agreement.
However, in the event of a party's gross negligence or willful breach, the
breaching party will remain liable for any and all damages, costs and expenses
sustained or incurred by the non-breaching party and will be liable to the
non-breaching party for damages up to $150,000 of out of pocket costs and
expenses. The payment of the costs and expenses is not an exclusive remedy but
is in addition to the options granted pursuant to the Stock Option Agreement.

AMENDMENT, EXTENSION AND WAIVER

         At any time prior to the Effective Time, whether before or after the
approval of Cargill's shareholders, the parties may amend the Merger Agreement,
extend the time for the performance of any of the obligations or other acts of
any other party hereto, waive any inaccuracies in the representations and
warranties contained therein or in any document delivered pursuant thereto, or
waive compliance with any of the agreements or conditions with respect to
covenants of the parties or closing conditions of the Merger; provided, however,
that there may not be, without further approval of Cargill shareholders, to the
extent required by law, any amendment, extension or waiver of the Merger
Agreement which materially changes the amount or form of the consideration to be
delivered to the Cargill shareholders other than as may be expressly
contemplated by the Merger Agreement. The Merger Agreement may not be amended
except by an instrument in writing signed on behalf of each of the parties
thereto. Any agreement on the part of any party to any extension or waiver shall
be valid only if set forth in an instrument in writing signed on behalf of such
party, but such waiver or failure to insist on strict compliance with such
obligation, covenant, agreement or condition shall not operate as a waiver of,
or estoppel with respect to, any subsequent or other failure.

   
REGULATORY APPROVALS

         The Merger and resultant acquisition by Westbank of Cargill are subject
to the prior approval of the Federal Reserve Bank of Boston (the "Reserve
Bank"), acting on delegated authority from the Board of Governors of Federal
Reserve System, under the Bank Holding Company Act of 1956, as amended (the
"BHCA"), and applicable regulations. The required 
    

                                      -64-
   67

   
    
application to the Reserve Bank has been filed by Westbank. In reviewing the
application, the Reserve Bank must take into consideration, among other factors,
the financial and managerial resources and future prospects of the institutions
and the convenience and needs of the communities to be served. In addition,
under the BHCA, the Merger may not be consummated until the 30th day following
the date of Reserve Bank approval of the Merger, during which time the
Department of Justice may challenge the Merger on antitrust grounds. The
commencement of an antitrust action during the waiting period would stay the
effectiveness of such approval unless a court specifically orders otherwise.

         The acquisition of Cargill by Westbank is also subject to the prior
approval of the MBBI, which must determine in connection with the application
that has been filed by Westbank that the Merger does not unreasonably affect
competition and that it promotes public convenience and advantage.

   
         The Merger also is subject to the approval of the Commissioner of the
Connecticut Department of Banking (the "Banking Commissioner") pursuant to
Sections 36a-411, 36a-184 and 36a-34 of the Connecticut General Statutes. Under
applicable Connecticut law, in considering the proposed transaction, the Banking
Commissioner is required to determine whether (1) the laws of the home state of
such out-of-state holding company authorize under conditions no more restrictive
then those imposed by the State of Connecticut, as determined by the
Commissioner, a Connecticut holding company to acquire and retain direct or
indirect ownership or control of 10% or more of the voting stock of the
out-of-state holding company whose home state is such state; and (2) the
proposed transaction can reasonably be expected to produce benefits to the
public and whether such benefits clearly outweigh possible adverse effects,
including, but not limited to, an undue concentration of resources and decreased
or unfair competition. The Banking Commissioner shall not approve the
transaction, however, unless the Banking Commissioner considers whether: (i) the
investment and lending policies of the subsidiary bank to be acquired are
consistent with safe and sound banking practices and will benefit the economy of
the state; (ii) the services or proposed services of the subsidiary bank are
consistent with safe and sound banking practices and will benefit the economy of
the state; (iii) the out-of-state holding company has sufficient capital to
ensure, and agrees to ensure, that the subsidiary bank will comply with
applicable minimum capital requirements; (iv) the parent corporation has
sufficient managerial resources to operate the subsidiary bank in a safe and
sound manner; and (v) the proposed transaction will not substantially lessen
competition in the banking industry of the state. Any interstate transactions
shall be effected in accordance with laws applicable to activities conducted by
Connecticut holding companies. The Banking Commissioner shall not approve the
proposed transaction unless the Banking Commissioner finds, in accordance with
applicable regulations, that the out-of-state holding company's subsidiary bank
and the Connecticut subsidiary bank have a record of compliance with the
requirements of the Community Reinvestment Act of 1977, 12 U.S.C. Section 2901
et seq., as from time to time amended, Section 36a-34 of the General Statutes of
Connecticut, as amended, and applicable consumer protection laws; and the
Connecticut subsidiary bank will provide adequate services to meet the banking
needs of all community residents, including low income residents and moderate
income residents, in accordance with a plan submitted by Westbank and Cargill
Bank.
    


                                      -66-
   68

   
    
         Because the proposed transaction will be effected pursuant to a
transaction between a Connecticut holding company and an out-of-state holding
company, the Banking Commissioner in accordance with Section 36a-184 of the
Connecticut General Statutes must be informed of (1) the background and identity
of the acquiror; (2) the source and amount of funds or other consideration to be
used and any arrangements, agreements or understandings with the out-of-state
holding company; (3) full audited financial information for the preceding five
fiscal years, as well as, current (not later than 90 days prior to filing with
the Banking Commissioner) unaudited financial information; (4) any plans to
merge or consolidate or to make any material changes in the Connecticut holding
company's corporate structure or management; (5) the number of shares proposed
to be acquired, the terms of the offer and a statement as to the method by which
the fairness of the proposal was arrived at; (6) information with respect to any
contracts, arrangements or understandings with respect to the securities of the
Connecticut holding company; (7) information with respect to the purchase of
securities of the Connecticut holding company and out-of-state holding company
within the preceding twelve month period; (8) information regarding any
recommendations to purchase securities of either bank holding company within the
preceding twelve month period; (9) copies of all agreements regarding the
proposed transaction; and (10) any additional information the Banking
Commissioner may require for the protection of the depositors, security holders
of the Connecticut holding company or in the public interest. An application for
approval of the proposed transaction has been filed with the Banking
Commissioner.

         Although there can be no assurances given that all regulatory approvals
will be received for the Merger and resultant acquisition by Westbank of
ownership and control of Cargill, the parties believe that all required
regulatory approvals will be obtained.

         The parties are not aware of any other regulatory approvals or filings
that are required for consummation of the Merger, except as described above.
Should any other approvals or filings be required, it is presently contemplated
that such approvals or filings will be sought or made, as appropriate. There can
be no assurances given, however, that any other approvals, if required, will be
obtained.

         The Merger will not be consummated unless all of the regulatory
approvals or other filings pertaining to the transactions contemplated by the
Merger Agreement, are obtained or made, as appropriate. See "THE
MERGER-Conditions to Consummation of the Merger" above.

EXPENSES

         Each party will pay its own expenses in connection with the Merger,
subject to certain provisions to the contrary contained in the Merger Agreement.

STOCK OPTION AGREEMENT

   
         Simultaneously with the execution of the Merger Agreement, Westbank and
Cargill entered into the Stock Option Agreement. Pursuant to the Stock Option
Agreement, Cargill granted to Westbank an option (the "Option") to purchase,
subject to adjustment in certain events, up to 84,804 shares of Cargill Common
Stock at an exercise price of $12.00 per share, subject to adjustment if
additional shares of Cargill Common Stock are issued or become outstanding after
July 15, 1998 (the "Option Shares"). The Option becomes exercisable in whole or
in part, after the 
    


                                      -67-
   69
occurrence of both an Initial Triggering Event and a Subsequent Triggering Event
(each as defined below).

         The term "Initial Triggering Event" means the occurrence at any time
after July 15, 1998 of: (i) the agreement by Cargill or any subsidiary thereof
to enter into, or the approval or acceptance by the Cargill Board of or
recommendation by the Cargill Board to Cargill's shareholders of any transaction
involving a merger or consolidation, a purchase, lease or other acquisition of
all or substantially all of the assets of Cargill or any significant subsidiary
of Cargill (except as contemplated by the Merger Agreement), or a purchase or
other acquisition of securities representing 10% or more of the voting power of
Cargill or any significant subsidiary of Cargill (each of the foregoing an
"Acquisition Transaction") without Westbank's prior written consent; (ii) the
acquisition by any person (other than Westbank, its subsidiaries and any Cargill
subsidiary acting in a fiduciary capacity) owning beneficially less than 10% of
the outstanding shares of Cargill Common Stock on July 15, 1998 of beneficial
ownership or the right to acquire beneficial ownership of 10% or more of the
outstanding shares of Cargill Common Stock; (iii) the making by any person,
other than Westbank or any subsidiary of Westbank, of a bona-fide proposal to
Cargill or its shareholders to engage in an Acquisition Transaction by public
announcement or written communication that shall be or become the subject of
public disclosure; (iv) the breach by Cargill after a proposal as described in
the preceding clause (iii) of certain covenants in the Merger Agreement, unless
remedied within an applicable notice period; (v) the filing by any person other
than Westbank or any subsidiary of Westbank, other than in connection with a
transaction to which Westbank has given its prior written consent, of an
application or notice with the Federal Reserve Board or other federal or state
bank regulatory authority, which application or notice has been accepted for
processing, for approval to engage in an Acquisition Transaction; or (vi)
Cargill or any subsidiary of Cargill shall have authorized, recommended,
proposed or publicly announced, without Westbank's prior written consent, its
intention to authorize, recommend or propose to engage in an Acquisition
Transaction with any person other than Westbank or any subsidiary of Westbank or
the Cargill Board shall, or announce its intent to, publicly withdraw or modify
in any manner adverse to Westbank, its recommendation that Cargill Shareholders
approve the transactions contemplated by the Merger Agreement.

   
         The term "Subsequent Triggering Event" means either (i) the acquisition
after July 15, 1998 by any person of beneficial ownership of 15% or more of the
then outstanding Cargill Common Stock; or (ii) the occurrence of the Initial
Triggering Event described in subparagraph (i) of the foregoing paragraph,
except that, in respect of the purchase or other acquisition of securities of
Cargill or any significant subsidiary of Cargill, the percentage of voting power
represented by such securities shall be 10.01% rather than 10%.

         The Option will expire upon the earliest of:

         (i)      the Effective Time of the Merger;

         (ii)     termination of the Merger Agreement in accordance with the
                  provisions thereof if such termination occurs prior to the
                  occurrence of an Initial Triggering Event; or
    


                                      -68-
   70

   
    
         (iii)    Eighteen months after the termination of the Merger Agreement
                  in accordance with the provisions thereof after the occurrence
                  of an Initial Triggering Event.

         The Stock Option Agreement provides that Cargill shall promptly notify
Westbank in writing of the occurrence of any Initial Triggering Event or
Subsequent Triggering Event. If Westbank chooses to exercise the Option it shall
send Cargill written notice which shall include the total number of shares it
will purchase. Once Westbank tenders the applicable purchase price it shall be
deemed the holder of record of shares of Cargill Common Stock.

         Notwithstanding the termination of the Merger Agreement, Westbank will
be entitled to purchase those Option Shares with respect to which it has
exercised the Option, in whole or in part, prior to the termination of the
Option upon (i) the consummation of any merger, consolidation or similar
transaction involving Cargill or any purchase, lease or other acquisition of all
or a substantial portion of the assets of Cargill other than an Acquisition
Transaction or (ii) the acquisition by any person of beneficial ownership of 50%
or more of the outstanding shares of Cargill Common Stock. Westbank may also by
written notice require Cargill to repurchase the unexercised Option in whole or
in part (to the extent not otherwise prohibited by applicable law or
regulations), at a purchase price intended to provide Westbank with the same
economic benefit as it would realize if it exercised the Option and subsequently
sold the Option Shares. Westbank may also by written notice require Cargill to
repurchase any Option Shares that it has acquired upon exercise of the Option
(to the extent not otherwise prohibited by applicable law or regulations). The
potential liability of such a repurchase to Cargill would be equal to the amount
by which the "market offer price" exceeds $12.00 per share multiplied by the
number of shares represented by the Option. The term "market offer price" is
defined within the Stock Option Agreement as the highest of: (i) the price per
share at which a tender offer or exchange offer has been made; (ii) the price
per share to be paid by any third party agreement with Cargill; (iii) the
highest closing price per share within a six-month period preceding notice of a
repurchase, or (iv) should a sale of all or a substantial portion of Cargill's
assets occur, the sum of the price paid for such assets and the current market
value of the remaining assets of Cargill divided by the number of shares of
Cargill Common Stock outstanding at the time of sale. Cargill anticipates that
it would fund any such repurchase of the unexercised Option or Option Shares out
of working capital.

         The Stock Option Agreement additionally provides for substitute options
(the "Substitute Options") in an acquiring corporation or any controlling entity
of the acquiring corporation should Cargill enter into an agreement to (i)
consolidate or merge not leaving Cargill as the surviving corporation; (ii)
permit a merger with Cargill and exchange Cargill Common Stock for the stock or
cash of any other property or (iii) the sale or transfer of all or substantially
all of its assets.

         The Stock Option Agreement was required by Westbank as a condition to
its entering into the Merger Agreement, and is intended to increase the
likelihood that the Merger will be consummated in accordance with the terms of
the Merger Agreement. The Stock Option Agreement may have the effect of
discouraging persons who might now or prior to the Effective Time be interested
in acquiring all of or a significant interest in Cargill from considering or
proposing such an acquisition.

SHAREHOLDERS' AGREEMENTS

         Cargill directors and executive officers, who own a total of 21.9%
shares of Cargill Common Stock, representing approximately 63,495% of the shares
of Cargill Common Stock issued and outstanding on the Record Date, have executed
the Cargill Shareholders' Agreements, pursuant to which such shareholders have
agreed to certain restrictions on their respective shares of Cargill Common
Stock. Specifically, such shareholders agreed, with respect to all presently
owned or after-acquired stock, (a) to vote such stock in favor of the Merger and
against any other merger or acquisition transaction with a party other than
Westbank or its affiliates, and (b) generally not to sell, assign, transfer,
encumber or otherwise dispose of such stock.

         The Cargill Shareholders' Agreement shall remain in effect until the
earlier of the consummation of the Merger or the termination of the Merger
Agreement in accordance with its terms.

WESTBANK LETTER AGREEMENTS

         The directors and executive officers of Westbank have executed Westbank
Letter Agreements pursuant to which such individuals have agreed not to dispose
of their shares of Westbank Common Stock in order to preserve the ability to
account for the transaction as a "pooling of interests".

NO SOLICITATION

         Cargill and its officers, directors, employees, representatives and
agents will not, directly or indirectly, encourage, solicit, initiate or,
subject to the fiduciary obligations of the Cargill Board (as advised in writing
by outside counsel), participate in any discussions or negotiations with, or
provide any information to, any corporation, partnership, person or other entity
or group (other than Westbank and its affiliates or representatives) concerning
any merger, tender offer, sale of substantial assets, sale of shares of capital
stock or debt securities or similar transaction involving Cargill. However,
Cargill or the Cargill Board is not prohibited from taking and disclosing to
Cargill's shareholders a position with respect to a tender offer by a third
party pursuant to certain rules promulgated under the Securities Exchange Act of
1934, as amended or from making such disclosure to Cargill's shareholders which,
in the judgment of the Cargill Board with the written advice of outside counsel,
may be required under applicable law. Cargill will immediately communicate to
Westbank the terms of any proposal, discussion, negotiation or inquiry and the
identity of the party making such proposal or inquiry. Any such communication
shall be delivered no less promptly than by telephone within twenty-four hours
of Cargill's receipt of any such proposal or inquiry or its receipt of any
request for information from the Federal Reserve Board, Department of Justice or
any other governmental agency or authority with respect to any transaction
described in the first sentence above.

MANAGEMENT AND OPERATIONS AFTER THE MERGER

   
         Following the consummation of the Merger, Cargill Bank will maintain
its separate corporate existence, but will become a wholly-owned subsidiary of
Westbank. Cargill Bank's corporate headquarters will continue to be located in
Putnam, Connecticut. The management and boards of directors of Westbank is not
expected to change. Donald R. Chase, President and Chief Executive Officer and a
director of Westbank, will join the Cargill Bank Board, and a current director
of Cargill will join the Westbank Board. In addition, such other individuals as
may be designated by Westbank will be asked to serve on the Cargill Bank Board
to constitute a majority of the Cargill Bank Board of Directors and upon
consummation of the Merger, a new President and Chief Executive Officer for
Cargill Bank will be appointed by Westbank to replace Robert G. Eggleston, Jr.
who resigned in October 1998. Currently, Howard Stanton, III has been chosen to
serve as acting President of Cargill Bank throughout the date of the Merger.
    

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         The Merger Agreement provides that the provisions with respect to
indemnification existing in favor of, and all limitations on the personal
liability of, any director, officer or other employee of Cargill or Cargill Bank
contained in the Cargill's Certificate of Incorporation and Bylaws and Cargill
Bank's Charter and Bylaws on the date of the Merger Agreement with respect to
matters occurring prior to the Effective Time shall survive the Merger. Westbank
has agreed to use all reasonable efforts to cause to be maintained in effect for
a period of not less than three years from the Effective Time the current
policies of the directors' and officers' liability insurance of Cargill (or
substitute policies of at least the same coverage with terms and conditions that
are not less favorable than those presently maintained by Cargill), with respect
to matters occurring at or prior to the Effective Time.

EMPLOYMENT OBLIGATIONS

         Westbank will provide the employees of Cargill and its affiliates who
are so employed at the Effective Time with employee benefits, consistent with
industry practice, as Westbank in its sole discretion may determine. Following
the Effective Time, Westbank will honor in accordance with its terms the
deferred compensation plans, and the Cargill Employee Stock Ownership Plan which
was terminated in 1995 (collectively the "Cargill Benefit Plans") disclosed to
Westbank under the Merger Agreement, between Cargill and any director, officer
or employee thereof, and all provisions for benefits or other amounts earned or
accrued through the Effective Time under Cargill Benefit Plans.


   
CARGILL STOCK OPTIONS
    
   
         At the Effective Time, each then outstanding employee stock option to 
purchase Cargill Common Stock ("Cargill Stock Options") pursuant to the Cargill 
Stock option plans (collectively, the "Cargill Stock Option Plans") will be 
assumed by Westbank. Each Cargill Stock Option so assumed by Westbank shall 
continue to have and be subject to, the same terms and conditions set forth in 
the Cargill Stock Option Plans immediately prior to the Effective Time, except 
that (i) such 
    

                                      -70-
   73
   
Cargill Stock Options shall be exercisable for that number of whole shares of
Westbank Common Stock equal to the product of the number of shares of Cargill
Common Stock covered by the Cargill Stock Option multiplied by the Exchange
Ratio, provided that any fractional share of Westbank Common Stock resulting
from such multiplication shall be rounded up to the nearest share; and (ii) the
exercise price per share of Westbank Common Stock shall be equal to the exercise
price per share of Cargill Common Stock of such Cargill Stock Option, divided by
the Exchange Ratio, provided that such exercise price shall be rounded down to
the nearest cent.
    

RESALE OF WESTBANK COMMON STOCK

         The shares of Westbank Common Stock to be issued pursuant to the Merger
Agreement have been registered under the Securities Act of 1933, as amended by
means of the registration statement of which this Proxy Statement-Prospectus
forms a part. Accordingly, such shares should be freely transferable under the
Securities Act, except for shares issued to persons who are affiliates of
Cargill at the time of the Special Meeting and persons who are affiliates of
Westbank at the time of such proposed transfer. Such persons will generally be
able to resell such shares only pursuant to an effective registration statement
under the Securities Act or pursuant to a statutory or regulatory exemption or
"safe harbor" from the registration requirements of the Securities Act.
Affiliates of a person are other persons who control, are controlled by, or are
under common control with the person. The affiliates of a corporation are
generally thought to include its executive officers, directors and significant
(i.e., 10% or more) shareholders.

         Affiliates of Westbank who wish to dispose of shares of Westbank Common
Stock acquired in the Merger may utilize the "safe harbor" provided by Rule 144
promulgated under the Securities Act ("Rule 144"). Rule 144 permits, among other
things, the resale of such shares if certain conditions are met. These
conditions include the requirement that Westbank have filed all reports required
of it under the Exchange Act for the past 12 months, a limitation on the number
of shares sold by the affiliate in any three-month period, and a restriction on
the manner in which the sale is made. In most cases, a notice of proposed sale
must also be filed with the SEC.

   
         Persons who are affiliates of Cargill at the time of the Special
Meeting and are not affiliates of Westbank at the time of a proposed resale may
utilize the resale provisions of Rule 145 promulgated under the Securities Act
("Rule 145"). During the year following the Effective Time, such resale would be
subject to the satisfaction of the conditions imposed under Rule 144 which are
described above, other than the notice of proposed sale. After such one-year
period, only the condition relating to Westbank's Exchange Act reports is
applied and, after two years, Rule 145 would impose no restriction on
dispositions by persons who were not affiliates of Westbank for at least three
months preceding the proposed disposition.


         This Proxy Statement-Prospectus does not cover the resale of any shares
of Westbank Common Stock to be issued in the Merger. Westbank is not obligated
to file a registration statement under the Securities Act to facilitate resale
of any such shares.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         The following discussion summarizes the material U.S. federal income
tax consequences of the Merger, including certain consequences to shareholders
of Cargill who are citizens or residents of the United States and who hold their
shares as capital assets. It does not discuss all aspects of federal income
taxation that may be relevant to a particular Cargill shareholder in light of
his or her personal circumstances (for example, a Cargill shareholder who
acquired his or her shares of Cargill Common Stock pursuant to the exercise of
employee stock options or otherwise as compensation), or to Cargill shareholders
subject to special federal income tax treatment (such as insurance companies,
regulated investment companies, dealers in securities, certain retirement plans,
financial institutions, tax exempt organizations, persons subject to the
alternative minimum tax, persons who hold Cargill Common Stock as part of a
hedging or conversion transaction or foreign persons). In addition, this summary
does not address any aspects of state, local, foreign or other tax laws that may
be relevant to holders of Cargill Common Stock.

         It is the policy of the Internal Revenue Service ("IRS") not to rule
directly on the tax status of transactions such as the Merger, and no such
ruling will be sought. Each of Westbank's and Cargill's respective obligations
to effect the Merger is conditioned upon its receipt from legal counsel of an
opinion dated as of the Closing Date, in form and substance reasonably
satisfactory to it, substantially to the effect that for federal income tax
purposes the Merger constitutes a reorganization within the meaning of Section
368 of the Internal Revenue Code (noting, however, that the nontaxability of the
shareholders of Cargill resulting from such reorganization does not extend to
cash received in lieu of a fractional share interest in Westbank Common Stock or
cash received by dissenting shareholders, if any). Such opinions are not binding
on the IRS and would not, in any event, prevent the IRS from challenging the
tax-free nature of the Merger under the Internal Revenue Code.

         As noted above, Cargill's obligation to effect the Merger is
conditional on delivery of an opinion of legal counsel, or other tax advisor,
based upon certain customary representations and warranties set forth therein,
substantially to the effect that for federal income tax purposes the Merger
constitutes a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code. If the receipt of such opinion were waived and if the
material federal income tax consequences to Cargill shareholders were materially
different from those set forth below, Cargill would resolicit the approval of
its shareholders before it proceeded with the Merger. Based on such opinion, and
subject to the foregoing, the material federal income tax consequences to
holders of Cargill Common Stock would be as set forth below.

   
         No gain or loss will be recognized by Westbank, Park West Bank, Cargill
or Cargill Bank by reason of the Merger.
    

   
    


                                      -72-
   75
   
         No gain or loss will be recognized by Cargill shareholders upon receipt
of Westbank Common Stock in exchange for their Cargill Common Stock, except that
a holder of Cargill Common Stock who receives cash in lieu of a fractional share
of Westbank Common Stock will recognize gain or loss equal to the difference
between the amount of such cash and the tax basis allocated to such
shareholder's fractional share of Westbank Common Stock.
    
         The tax basis of the Westbank Common Stock received by a Cargill
shareholder will be the same as the aggregate tax basis of such shareholder's
Cargill Common Stock exchanged therefor, decreased by any cash received in lieu
of fractional shares.

         The holding period of the Westbank Common Stock in the hands of a
Cargill shareholder will include the holding period of such shareholder's
Cargill Common Stock exchanged therefor, provided that such Cargill Common Stock
is held as a capital asset at the Effective Time.

         A Cargill shareholder who exercises dissenters' rights and receives
cash will recognize gain for federal income tax purposes, the tax rate on which
will depend upon the holding period for his or her Cargill Common Stock. The
exchange of shares for cash upon the exercise of dissenters' rights could be
treated as substantially equivalent to a dividend and, therefore, taxed as
ordinary income if the recipient of cash owns or constructively owns other
shares of Westbank Common Stock. Shares owned by spouses, children,
grandchildren, parents and other relatives and by entities that are 50% owned by
a shareholder are generally treated as constructively owned by that shareholder.

         THE FOREGOING DISCUSSION IS BASED ON CURRENTLY EXISTING PROVISIONS OF
THE INTERNAL REVENUE CODE, EXISTING AND PROPOSED U.S. TREASURY REGULATIONS
THEREUNDER AND CURRENT ADMINISTRATIVE RULINGS AND COURT DECISIONS. ALL OF THE
FOREGOING ARE SUBJECT TO CHANGE AND ANY SUCH CHANGE COULD AFFECT THE CONTINUING
VALIDITY OF THIS DISCUSSION. CARGILL SHAREHOLDERS SHOULD CONSULT THEIR OWN TAX
ADVISERS WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER TO THEM,
INCLUDING THE APPLICATION AND EFFECT OF STATE, LOCAL AND FOREIGN TAX LAWS.

ACCOUNTING TREATMENT

         It is anticipated that the Merger will be accounted for as a "pooling
of interests" transaction under GAAP. Under the pooling of interests method of
accounting, the recorded assets and liabilities of the separate companies
generally become the recorded assets and liabilities of the combined
corporation. The assets of the constituent entities are recorded on the
resulting corporation's books at their historical cost.

                         INFORMATION REGARDING WESTBANK

     Westbank is a bank holding company established as a Massachusetts
corporation in 1983 and is registered under the Bank Holding Company Act of
1956, as amended, with its principal asset being the stock of Park West Bank.
Substantially all operating income and net income of Westbank are presently
accounted for by Park West Bank. Park West Bank is chartered as a state bank and
trust company by the Commonwealth of Massachusetts, is a member of the FDIC and
is subject to regulation by the Massachusetts Commissioner of Banks and the
FDIC. A full range of retail banking services is furnished to individuals,
businesses, and nonprofit organizations through twelve banking offices located
in Hampden County. Such services include a wide range of checking and savings
accounts, loans, safe deposit facilities, and automated teller machines at
selected branch locations. Park West Bank also provides lending, depository and
related financial services to commercial, industrial, financial, and
governmental customers. In the lending area, these include short and long term
loans and revolving credit arrangements, letters of credit, inventory and
accounts receivable financing, real estate construction lending, and mortgage
loans.
    
         Park West Bank also operates a Trust Department providing services
normally associated with holding property in a fiduciary or agency capacity. The
value of the property held by the Trust Department at June 30, 1998 amounted to
$115,895,000 and is not included in the accompanying financial statements
because such items are not assets of Park West Bank.

         As of June 30, 1998, Westbank and its subsidiaries had the equivalent
of 119 full time employees and staff.

         Westbank's banking, real estate activity and trust services are
competitive with other Massachusetts financial institutions. Its service area is
in Western Massachusetts, primarily Hampden County. Westbank's competitors
include other commercial banks, mutual savings banks, savings and loan
association, credit unions, consumer finance companies, loan offices, money
market funds, and other financial organizations.

         Competition for trust services by major commercial banks is high, with
continuing efforts by those banks to solicit new business. The Trust Department
prides itself as one of the few remaining corporate fiduciaries providing
personal services locally. Insurance companies, mutual savings banks, investment
counseling firms, and other business firms and individuals also offer active
competition for such business.

                          INFORMATION REGARDING CARGILL

         Cargill is a unitary savings and loan holding company established as a
Delaware Corporation in 1988 with its principal asset being the stock of Cargill
Bank. Cargill Bank of Connecticut (now known as Cargill Bank) was chartered as a
mutual savings and loan association in February 1916, and converted to a stock
form in February, 1988. Cargill was formed in September 1989 as a result of the
reorganization of Cargill Bank to a stock holding company form. Neither Cargill
nor Cargill Bank has never been involved in any mergers or acquisitions other
than the formation of the Cargill Bank.

         The business of Cargill Bank is to attract deposits from the general
public and to make loans secured by mortgages on residential and other real
estate, enabling borrowers to purchase, refinance, construct or improve
property. In addition, Cargill Bank makes consumer loans and holds investment
securities. Cargill Bank's market area is in the northeastern part of
Connecticut and is made up primarily of the towns of Putnam, Woodstock, Pomfret,
Thompson, Killingly and Eastford. Cargill Bank operates three offices, the main
office in Putnam and branch offices in Quinebaug, which is part of Thompson, and
Woodstock. Cargill Bank's market area, although predominantly rural in
character, is only 30 miles south of Worcester, Massachusetts. The region in
which Cargill Bank operates also is centrally located between Boston,
Massachusetts, Providence Rhode Island and Hartford, Connecticut. Over 95% of
Cargill Bank's mortgage loans are secured by real property located in
Connecticut. The principal executive offices of Cargill is located at 163
Providence Street, Putnam, Connecticut. Its telephone number is (860) 963-2265.
    

           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                      AND RESULTS OF OPERATIONS OF CARGILL

         CARGILL'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS IS DESIGNED TO PROVIDE A BETTER UNDERSTANDING OF THE
SIGNIFICANT CHANGES AND TRENDS RELATED TO CARGILL'S FINANCIAL CONDITION, RESULTS
OF OPERATIONS, LIQUIDITY AND CAPITAL RESOURCES. THE DISCUSSION SHOULD BE READ IN
CONJUNCTION WITH THE FINANCIAL STATEMENTS OF CARGILL ELSEWHERE IN THIS PROXY
STATEMENT-PROSPECTUS.
                                      -75-
   78
         The following financial review presents an analysis of Cargill's
results of operations for each of the periods presented. Cargill has not engaged
in any business apart from owning Cargill Bank. Accordingly, the following
discussion and analysis of the financial condition and results of operations
refers to Cargill Bank. The discussion and analysis of the financial condition
and health of operations is based on Cargill's consolidated statements of
financial condition, and the related consolidated statements of operations,
changes in stockholders' equity, cash flows and the notes to these consolidated
financial statements. These statements, including the Report of Independent
Auditors, should be read together with Management's Discussion and Analysis of
Financial Condition and Results of Operations.

         Cargill Bank's revenues are derived principally from interest earned on
loans and, to a lesser extent, from interest earned on interest-bearing deposits
and investments. The operations of the Cargill Bank, and the thrift industry in
general, are influenced significantly by general economic conditions and by
policies of financial institution regulatory agencies, including the Office of
the Comptroller of the Currency ("OCC"),OTS, FDIC and the Connecticut Department
of Banking. Cargill Bank's cost of funds is influenced by interest rates on
competing investments and general market interest rates. Lending activities are
affected by the demand for real estate and other types of loans, which in turn
is affected by the interest rates at which such financing may be offered.

         Cargill Bank's net income depends to a significant degree upon its net
interest income, which is the difference between the interest income earned on
its interest-earning assets and the interest expense paid on its
interest-bearing liabilities. Cargill Bank, like other thrift institutions, is
subject to interest rate risk to the degree that its interest-bearing
liabilities mature or reprice at different times, or on a different basis, than
its interest-earning assets.

YEAR ENDED SEPTEMBER 30, 1997 AND SEPTEMBER 30, 1996

         Cargill Bank's assets continue to be comprised primarily of mortgage
loans (mostly 1-4 family, owner occupied) with maturities of up to 30 years.
Such assets were historically fixed rate and funded with low-cost, stable
deposit accounts. Beginning in the late 1970s and continuing through this date,
interest rate volatility has made the market sensitive to this type of
fixed-rate loan product. In response to this market trend, Cargill Bank has
moved toward originating a greater percentage of adjustable rate mortgage loans.
As of September 30, 1997, the adjustable mortgage loans represented 75.5% of the
total loan portfolio.

         The 1997 fiscal year produced an increase in capital from $2,971,000 to
$3,167,000. The net increase in capital of $196,000 was a result of net income
for the fiscal year of $153,000, the net effect of a former director exercising
his stock options, and the net effect of Cargill Bank adjusting the value of
investments "Available-for-Sale". Assets also rose from $46,894,000 to
$47,302,000. There was a decrease in non-performing assets classification
attributable to the continued resolution of such assets throughout the year
ended September 30, 1997. Almost all of these loans are secured by 1 - 4 family
properties.

         The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") imposes significant regulatory restrictions and requirements on
banking institutions insured by the FDIC and their holding companies. FDICIA
established capital categories into which financial institutions are placed
based on capital level. Each capital category establishes different degrees of
regulatory restrictions which can apply to a financial institution. As of
September 30, 1997, Cargill Bank's capital was at a level that placed Cargill
Bank in the "well capitalized" category as defined by FDICIA.

         FDICIA imposes a variety of other restrictions and requirements on
insured banks. These include significant regulatory reporting requirements such
as insuring that a system of risk-based deposit insurance premiums and civil
money penalties for inaccurate deposit reporting exists. In addition, FDICIA
imposes a system of regulatory standards for financial institutions and holding
company operations, detailed truth in savings disclosure requirements, and
restrictions on activities authorized by state law but not authorized for
national financial institutions.

         The regulatory risk-based capital requirements take into account the
different risk categories of banking organizations by assigning risk weights to
assets and the credit equivalent amounts of off-balance sheet exposures. In
addition, capital is divided into two tiers. For Cargill Bank, Tier 1 includes
the common stockholders' equity. Total capital includes Tier 1 items as well as
Tier 2 or Supplementary Capital. Included in Cargill's Tier 2 capital is the
allowance for loan losses. Net unrealized gains (losses) on securities available
for sale are not included for regulatory capital purposes.

The following are the risk-based capital ratios for Cargill and Cargill Bank at
September 30:



                                                      1997       1996       1995

DISCUSSION OF MARKET RISK

         Market risk is the loss due to adverse changes in market prices and
rates. The management of this risk, coupled with directives to build shareholder
value and profitability, is an integral part of Cargill's overall operating
strategy. Cargill's approach to risk management, primarily interest rate risk
management, is quite basic and concentrates on fundamental strategies to
restructure the balance sheet and composition of assets and liabilities. Since
Cargill does not utilize interest rate futures, swaps or options transactions,
its asset/liability profile is not complex. It reflects a simple approach to
managing risk through the use of fixed and adjustable rate loans, rate
insensitive checking accounts as well as a combination of fixed and variable
rate deposit products. Bank policy includes required limits on the sensitivity
of net interest income under various interest rate scenarios.

         Cargill Bank seeks to control its interest rate risk exposure in a
manner that will allow for adequate levels of earnings and capital over a range
of possible interest rate environments. Cargill Bank has adopted formal policies
and practices to monitor and manage interest rate risk exposure. As part of this
effort Cargill Bank actively manages interest rate risk through the use of a
simulation model which measures the sensitivity of future net interest income to
changes in interest rates. In addition, Cargill Bank regularly monitors interest
rate sensitivity through gap analysis, which measures the terms to maturity or
next repricing date of interest-earning assets and interest-bearing liabilities.

         On a quarterly basis, an interest rate risk exposure compliance report
is prepared and presented to Cargill Bank's Board of Directors. This report
presents an analysis of the expected change in net interest income resulting
from an increase or decrease in the level of interest rates. All changes are
measured as percentage changes from the projected net interest income in the
flat rate scenario. The calculated estimates of change in net interest income
are compared to current limits established by management and approved by the
Board of Directors. The following is a summary of the interest rate exposure
report as of September 30, 1997:



Change in Interest Rates                                    Percentage Change in
   (in Basis Points)                                         Net Interest Income
                                                            
        +200                                                       12.72%
        Level                                                       0.00%
        -200                                                      (17.20)%


         The model utilized to create the report presented above makes various
estimates at each level of interest rate change regarding cash flows from
principal repayments on loans and mortgage-backed securities and/or call
activity on investment securities. Actual results could differ significantly
from these estimates which would result in significant differences in the
calculated projected change.

         In order to reduce the exposure to interest rate fluctuations, Cargill
Bank has developed strategies to manage its liquidity, shorten the effective
maturities of certain interest-earning assets and increase the effective
maturities of certain interest-bearing liabilities. Cargill Bank has focused its
residential lending on a combination of fixed and adjustable rate mortgages.
Commercial loans, commercial mortgages and consumer lending focus on adjustable
and short term loans. Cargill Bank also attempts to maintain and/or increase its
savings and transaction accounts which are considered relatively insensitive to
changes in interest rates.

         Cargill Bank also measures sensitivity to changes in interest rates
using interest rate sensitivity gap analysis which is the difference between the
cash flow amounts of interest-sensitive assets and liabilities that will be
refinanced (or repriced) during a given period. For example, if the asset amount
to be repriced exceeds the corresponding liability amount for a certain day,
month, year, or longer period, the institution is in an asset-sensitive gap
position. In this situation, net interest income would increase if market
interest rates rose or decrease if market interest rates fell. If,
alternatively, more liabilities than assets will reprice, the institution is in
a liability-sensitive position. Accordingly, net interest income would decline
when rates rose and increase when rates fell. Also, these examples assume that
interest-rate changes for assets and liabilities are of the same magnitude,
whereas actual interest-rate changes generally differ in magnitude for assets
and liabilities.

         The following table sets forth the distribution of the repricing of
Cargill Bank's earning assets and interest bearing liabilities as of September
30, 1997, the interest rate sensitivity gap, (i.e., interest rate sensitive
assets less interest rate sensitive liabilities), the cumulative interest rate
sensitivity gap, the interest rate sensitivity gap ratio and the cumulative
interest rate sensitivity gap ratio. The table also sets forth the time periods
in which earning assets and interest-bearing liabilities will mature or may
reprice in accordance with their contractual terms. However, the table does not
necessarily indicate the impact of general interest rate movements on the net
interest margin since the repricing of various categories of assets and
liabilities is subject to competitive pressures and the needs of Cargill Bank's
customers. In addition, various assets and liabilities indicated as repricing
within the same period may in fact reprice at different times within such period
and at different rates.

DISCUSSION OF MARKET RISK

         The presentation of a run off and repricing of savings accounts and NOW
accounts is based on Cargill Bank's historical experience with $1,075,000 and
$717,000, respectively, included in the three month to one year category and the
remainder placed in the one to five year category of the interest bearing
liabilities.

         Cargill seeks to manage the mix of asset and liability maturities to
control the effect of changes in the general level of interest rates on net
interest income. In periods of rising interest rates, Cargill's negative
interest rate sensitivity gap as to earning assets and interest-bearing
liabilities maturing in less than one year may cause a diminuation of Cargill's
income; correspondingly, in periods of declining interest rates, a negative
interest rate sensitivity gap may provide additional income. Except for its
effect on the general level of interest rates, inflation does not have a
material impact on Cargill's earnings due to the rate of variability and
short-term maturities of its earning assets.

     placed in non-accrual status, interest income is recorded to the extent
     actually received in cash or is applied to reduce principal.

Analysis further describes the change in yields.

RATE/VOLUME ANALYSIS OF INTEREST MARGIN ON EARNING ASSETS

     The dollar amounts of interest income and interest expense fluctuate
depending upon changes in interest rates and upon changes in amounts (volume) of
Cargill's interest-earning assets and interest-bearing liabilities. Changes
attributable to (i) changes in volume (changes in average outstanding balances
multiplied by the prior period's rate), (ii) changes in rate (changes in average
interest rate multiplied by the prior period's volume), and (iii) changes in
rate/volume (changes in rate times the change in volume that were allocated
proportionately to the changes in volume and the changes in rate) were as
follows:

LIQUIDITY

              Liquidity management requires close scrutiny of the mix and
maturity of deposits and borrowings and short-term investments. Cash and due
from banks, interest bearing deposits, investment securities and mortgage-backed
securities, as compared to deposits, are used by Cargill to compute its
liquidity on a daily basis as adjusted for regulatory purposes. Cargill is
subject to Regulation D of the Federal Reserve Bank


                                      -81-
   84
(FRB), which requires depository institutions to maintain reserve balances on
deposit with the FRB based on certain average depositor balances. Cargill is in
compliance with Regulation D. Management of Cargill believes that its current
liquidity is sufficient to meet current and anticipated funding needs.

              Cargill's loan portfolio is not concentrated within a single
industry nor a group of related industries, however, underlying collateral
values are dependent upon market fluctuations in the Northeastern Connecticut
area. The aggregate amount of loans to executive officers, directors and
organizations with which they are associated amounted to $343,000 or 10.8% of
stockholders' equity as of September 30, 1997 compared to $390,000 or 13.1% as
of September 30, 1996.

              The following table provides the maturity distribution and
sensitivity to changes in interest rates of commercial loans and commercial real
estate construction loans at September 30, 1997:

              All of the commercial loans which mature beyond one year have
fixed rates.

              In the normal course of business, various commitments and
contingent liabilities are outstanding, such as guarantees, standby letters of
credit, commitments to extend credit and various financial instruments with
off-balance-sheet risk that are not reflected in the financial statements. The
most significant of these are commitments to grant loans and commitments to
advance funds under existing loan agreements which were $76,000 and none,
respectively, at September 30, 1997 and $479,000 and $201,000, respectively, in
1996. See further discussion in Note 12 to the Consolidated Financial
Statements.

LOAN LOSS EXPERIENCE

              The provision for loan losses is an amount added to the allowance
against which loan losses are charged. The provision for loan losses is
dependent on actual net write-offs and an evaluation as to the collectibility of
the loan portfolio taking into consideration such factors as the financial
condition of individual borrowers, historical loss experience with respect to
various portfolio segments, current and near term economic conditions, and the
size of the portfolio. Based on these reviews, the allowance for loan losses at
September 30, 1997, is deemed to be adequate by management. In the determination
of the allowance for loan losses management obtains independent appraisals for a
significant number of properties.

              The following table sets forth the historical relationship among
the average amount of loans outstanding, the allowance for loan losses,
provision for loan losses charged to operating expenses, losses charged off,
recoveries and selected ratios:

              The approach Cargill uses in determining the adequacy of the
allowance for loan losses is the combination of a target reserve and general
reserve allocation. Quarterly, based on an internal review of the loan
portfolio, Cargill Bank identifies required reserve allocations targeted to
recognized problem loans that, in the opinion of management, have potential loss
exposure or questions relative to the adequacy of the collateral on these same
loans. The general reserve allocations are based on loss exposure and historical
results.

NON-PERFORMING ASSETS

LOANS

              Loans on which interest and principal payments are 90 days or more
past due are placed on a non-accrual basis (earlier if deemed appropriate) and
all interest accrued to that date is reversed. For the fiscal year ended
September 30, 1995 and earlier years, interest income on loans 90 days or more
past due continued to accrue when management determined that the collectibility
of principal and interest was not reasonably considered in doubt. When this
change was made in 1996, it did not have a material effect on the financial
statements . The following table sets forth information with regard to
non-performing loans as of the end of each year indicated:

              The gross amount of interest that would have been accrued at the
original contract rate on loans on a non-accrual basis (in thousands) was $20,
$62, $35, $9 and $2 for 1997, 1996, 1995, 1994 and 1993, respectively. The
decrease in non-accrual loans from 1996 is attributable to the continued
resolution of non-performing loans throughout 1997.

              Cargill Bank measures impairment of commercial loans by using the
present value of expected future cash flows discounted at the loan's effective
interest rate. Commercial real estate loans are generally measured based on the
fair value of the underlying collateral. Small balance homogenous loans,
including residential real estate and consumer loans, are collectively evaluated
for impairment based on the present value of expected future cash flows
discounted at the loan's effective interest rate or, as a practical expedient,
at the loan's observable market price or the fair value of the collateral if the
loan is collateral dependent.

              Cargill Bank evaluates each impaired loan to determine the
appropriate income recognition practice. Generally, income is recorded only on a
cash basis for impaired loans. Interest income recognized during 1997 and 1996
on impaired loans was not significant. At September 30, 1997 and 1996, the
recorded investment in impaired loans was $848,000 and $768,000 respectively,
for which no additional specific allowance for loan losses was recorded. For the
twelve months ended September 30, 1997, the average recorded investment in
impaired loans was $808,000 compared to $623,000 for year end 1996.

RESTRUCTURED LOANS

              A restructured loan is one for which Cargill Bank has modified the
contractual terms to provide a reduction in the rate of interest and, in most
instances, an extension of payments of principal or interest or both because of
a deterioration in the financial position of the borrower. Restructured loans
modified prior to October 1, 1995 which are performing in accordance with their
new terms are not included in non-accrual loans unless concern exists as to the
ultimate collection of principal or interest and are not considered to be
impaired. Those entered into after October 1, 1995 are considered to be impaired
as described in Note 1 to the financial statements. Restructured loans, which
are classified as accruing loans, amounted to $334,000 in 1995, $180,000 in
1994, and $100,000 in 1993. The following is an analysis of interest income
related to restructured loans which are classified as accruing loans:

              In the following sections of Management's Discussion and Analysis
of the Statements of Income, the comparative results of 1997, 1996 and 1995 will
be covered in greater detail. The principal earning assets of the holding
company consist of a savings and loan association, Cargill Bank. Noteworthy are
the effects of sources of income from earning assets and expense of
interest-bearing liabilities. Presented below is a comparative summary of
percentages of increases and decreases for each of the three years ended
September 30, 1997. The significant changes are discussed in the analysis that
follows the summary.

INTEREST INCOME

              Cargill's earning assets include a diverse portfolio of interest
earning instruments ranging from Cargill's core business of loan extensions to
interest-bearing securities and mortgage-backed securities. These earning assets
are financed through a combination of interest-bearing and interest-free
sources.

                                      -87-

              Total interest income for 1997 amounted to $3,568,000 as compared
to $3,459,000 for 1996 and $3,214,000 for 1995. For 1997 this represents an
increase of $109,000 or 3.1% over 1996, while interest income increased by
$245,000 or 7.6% in 1996 versus 1995. The increase in 1997 is the result of an
increase in average earning assets of $652,000 or 1.5% along with an increase of
13 basis points in average earning interest rate. The increase in 1996 over 1995
is the result of an increase in average earning assets of $245,000 combined with
a 36 basis point increase in average earning interest rate.

INTEREST EXPENSE

              Interest expense for 1997 on deposits and borrowings amounted to
$1,719,000 as compared to $1,766,000 in 1996 and $1,605,000 for 1995. Interest
expense decreased by $47,000 or 3% during 1997 compared to 1996 and 1996
interest expense increased by $161,000 or 10% versus 1995. The 1997 increase is
the result of an increase of average interest bearing liabilities of $454,000
and a 16 basis point decrease in the average rate of interest paid compared to
1996. The increase in interest expense during 1996 versus 1995 is the result of
an increase of average interest bearing liabilities of $1,833,000, combined with
a increase of 21 basis points on the average interest rate paid.

NET INTEREST INCOME

              Net interest income, the most significant component of earnings,
is the amount by which the interest generated by assets exceeds the interest
expense on liabilities.

              Cargill's management analyzes its performance by utilizing the
concepts of interest rate spread and net yield on earning assets. The interest
rate spread represents the difference between the yield on earning assets and
interest paid on interest-bearing liabilities. The net yield on earning assets
is the difference between the rate of interest on earning assets and the
effective rate paid on all funds, interest-bearing liabilities, as well as
interest-free sources (primarily demand deposits and stockholders' equity).

         The following table sets forth Cargill's net interest income on a
taxable equivalent basis:

and interest bearing liabilities which result in net interest income.

PROVISION FOR LOAN LOSSES

              The 1997 provision for loan losses totaled $116,000 compared with
$76,000 in 1996, a increase of 53%. During 1996, the provision decreased by
$141,000 versus 1995 representing a decrease of 65%. A full discussion appears
previously under the headings of Loan Loss Experience.

NON-INTEREST INCOME

              Income from sources other than interest was $268,000 in 1997, an
increase of $68,000 from the prior year and a increase of $81,000 versus 1995.
Non-interest income for 1997 reflects an increase in services on deposit
accounts and other non-interest income of $30,000 and increases from the gain on
sale of investments of $40,000 compared to 1996.

              Overall non-interest expense decreased during 1997 by $253,000
versus 1996 and increased $299,000 compared to 1995. During 1997, salaries and
benefits increased by $16,000 attributable to overall corporate growth during
1997. Occupancy remained level with 1996. Deposit insurance expense decreased
during 1997 due to the nonrecurrence of an additional deposit insurance expense
of $272,000 that Cargill Bank recorded for the year ended September 30, 1996 as
a result of legislation passed by Congress that imposed a one-time assessment.
Finally, other non-interest expense increased in 1997 by $29,000, also the
result of overall 1997 growth.

INCOME TAXES

              For the year ended September 30, 1997 Cargill recorded a tax
expense of $95,000 compared to 1996, when the Corporation recorded a tax benefit
of $78,000. The higher tax expense for 1997 was the result of higher pre-tax
earnings during 1997.

NET INCOME

              The net income for 1997 of $153,000 or $.58 per share basic and
$.54 per share diluted, is based on a weighted average of 262,569 basic and
285,680 diluted shares outstanding, compared with a net loss for 1996 or
$111,000 or $.42 per share basic and diluted based on a weighted average shares
of 262,305 basic and diluted. 1995 earnings was $73,000 or $.28 per share basic
and diluted and based on weighted average shares of 249,570 basic and diluted.

ACCOUNTING CHANGES

     In 1997, the Financing Accounting Standards Board issued a Statement of
Financial Accounting Standards SFAS No. 130, Reporting Comprehensive Income,
which establishes standards for reporting and displaying of comprehensive income
and SFAS No. 131, Disclosures about Segments of an Enterprise and Related
Information, which establishes standards for the way public companies report
information about operating segments in both interim and annual financial
statements and related disclosures. Cargill has not determined what, if any,
impact SFAS No. 131, will have on the operating segments reported nor the
related disclosures. SFAS No. 130 was adopted by Cargill on financial statements
that begin after December 15, 1997 and SFAS No. 131 will be effective for
Cargill's 1999 fiscal year.

YEAR 2000 COSTS

              Mindful of the need to sustain the integrity of its computer
system as the Year 2000 approaches, Cargill has taken steps to ensure that all
systems are ready to operate accurately on and beyond the Year 2000. Cargill
fully understands the need to prevent disruption of computer and technical
systems, and Cargill is committed to providing its customers with high quality
service.

              Cargill has designed its plan to address its Year 2000 concerns
based upon guidance from the Federal Financial Institutions Examining Council.
In addition, the OTS and the Connecticut State Banking Department monitors
Cargill's preparation for the Year 2000 on periodic basis.

              Cargill relies on an outside service bureau for almost all of its
data processing.


                                      -89-
   92
              Cargill's current state of readiness is that its equipment has
been tested and new equipment (data transmission equipment and teller machines)
has been ordered where necessary. Monitoring of the outside service bureau's
compliance continues on an ongoing basis and additional testing is scheduled for
early 1999 when Cargill's new equipment will be in place. At that time, Cargill
and the service bureau will advance the date on their equipment and run a series
of tests in insure both software and controlling hardware is functioning
properly.

              To date, Cargill has incurred approximately $2,000 in Year 2000
related expenses and has estimated that capital expenditures related to the Year
2000 issue will total approximately $210,000.

              Cargill's assessment of the risks of the Year 2000 compliance is
 forward looking information. As such, it is subject to risks and uncertainties
 that could cause actual results to differ materially from the
projected results discussed herein.

NINE MONTHS ENDED JUNE 30, 1998 AND JUNE 30, 1997

CHANGES IN FINANCIAL CONDITION

              Total consolidated assets amounted to $47,908,000 on June 30,
1998, compared to $47,302,000 on September 30, 1997. As of June 30, 1998 and
September 30, 1997, earning assets amounted to, respectively, $44,890,000 or 95%
of total assets, and $43,755,000 or 93% of total assets. Earning assets
increased slightly during the first nine months of 1998 as a result of Cargill
Bank's overall level of growth.

CHANGES IN RESULTS OF OPERATIONS

              For the nine months ended June 30, 1998, net income was $209,000
compared to $112,000 for the same period during 1997. Included in the results
for the nine months ended June 30, 1997 is a gain on the sale of securities
available for sale totaling $40,000.

              An overall increase in net interest income reflects a decrease in
volume and increase in interest rates on earning assets and a decrease in volume
and rates on interest-bearing deposits. Further analysis is provided in sections
on net interest revenue and supporting schedules.

ALLOWANCE FOR LOAN LOSSES AND NON-PERFORMING ASSETS

              Cargill recorded a provision for loan losses of $22,000 in the
nine months ended June 30, 1998 compared to $117,000 for the same period in
1997. Loans written off against the allowance for loan losses after recoveries
amounted to $7,000 of net recoveries for the nine months ended June 30, 1998.

              The allowance for loan losses at June 30, 1998 totaled $238,000 or
 .69% of total loans, as compared to $209,000 or .58% at September 30, 1997.

              Non-performing past due loans at June 30, 1998 aggregated $472,000
or 1.37% of total loans compared to $606,000 or 1.68% at September 30, 1997. The
percentage of non-performing and past due loans compared to total assets on
those same dates, respectively, amounted to 1.09% and 1.69%.

              Other real estate owned at June 30, 1998 totaled $44,000 and
stands at 0.09% to total assets at the end of the current period.

              Management has made every effort to recognize all circumstances
known at this time which could affect the collectibility of loans and has
reflected these in the provision for loan losses, the write down of other real
estate owned and impaired loans to fair value and other loans (watch list)
monitored by management, the charge-off of loans and the balance in the
allowance for loan losses. Management believes that the provision for the
current fiscal period and the balance in the allowance for loan losses are
adequate based on results provided by the loan grading system and circumstances
known at this time.

              Regulatory risk-based capital requirements take into account the
different risk categories of financial institutions by assigning risk weights to
assets and the credit equivalent amounts of off-balance sheet exposures.


              In addition, capital is divided into two tiers. For Cargill, Tier
1 includes the common stockholders' equity. Total capital includes Tier 1 items,
as well as Tier 2, or supplementary capital. Included in Cargill's Tier 2
capital is a portion of the allowance for loan losses. Net unrealized gains
(losses) on securities available for sale are not included for regulatory
capital purposes.

The following are risk-based capital ratios for Cargill and Cargill Bank at June
30, 1998:

     Tier 1 Risk Based Capital (minimum required 4.00%)
       - Cargill                                                       14.39 %

     Total Risk Based Capital (minimum required 8.00%)
       - Cargill                                                       15.40 %

              Management makes regular evaluations of the loan portfolio to
determine the adequacy of the level of the allowance for loan losses. Numerous
factors are considered in the evaluation, including a review of certain
borrowers' current financial status and credit standing, available collateral,
loss experience in relation to outstanding loans, the overall loan portfolio
quality, management's judgement regarding prevailing and anticipated economic
conditions, and other relevant factors.

                         REPORT OF INDEPENDENT AUDITORS


To the Board of Directors and Stockholders
Cargill Bancorp, Inc.


We have audited the consolidated statements of financial condition of Cargill
Bancorp, Inc. and subsidiary as of September 30, 1997 and 1996, and the related
consolidated statements of operations, changes in stockholders' equity and cash
flows for the years ended September 30, 1997, 1996 and 1995. These consolidated
financial statements are the responsibility of the Corporation's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. 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 consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Cargill Bancorp,
Inc. and subsidiary as of September 30, 1997 and 1996, and the results of its
operations and its cash flows for the years ended September 30, 1997, 1996 and
1995 in conformity with generally accepted accounting principles.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cargill Bancorp, Inc. (the "Corporation") is a savings and loan holding company
for Cargill Bank (the "Bank").

Business

Cargill Bank provides a full range of personal banking services to individual
and small business customers located primarily in Putnam, Connecticut and the
immediate surrounding vicinity. The Bank is subject to competition from other
financial institutions throughout the region. The Bank is also subject to the
regulations of certain state and federal agencies and undergoes periodic
examinations by those regulatory authorities.

Basis of presentation

The accounting and reporting policies of the Corporation and its subsidiary,
Cargill Bank conform to generally accepted accounting principles and to general
practices within the thrift industry.

In preparing the financial statements, management is required to make estimates
and assumptions that affect the reported amounts of assets and liabilities as of
the date of the balance sheet, and income and expenses for the period. Actual
results could differ from those estimates.

Material estimates that are particularly susceptible to significant change in
the near-term relate to the determination of the reserve for losses on loans and
the valuation of real estate acquired in connection with foreclosure or in
satisfaction of loans. While management uses available information to recognize
losses on loans and foreclosed real estate, future additions to the allowance
may be necessary based on changes in economic conditions, particularly in
Connecticut.

Principles of consolidation

The accompanying consolidated financial statements include the accounts of the
Corporation and its wholly-owned subsidiary, Cargill Bank. All significant
intercompany accounts and transactions have been eliminated in the
consolidation.

Cash and cash equivalents

For purposes of reporting cash flows, cash and cash equivalents include cash and
amounts due from depository institutions, and interest-bearing deposits.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Investment securities

Management determines the appropriate classification of a security at the time
of purchase. If management has the intent and the Bank has the ability at the
time of purchase to hold debt securities until maturity, they are classified as
held-to-maturity. These securities are carried at historical cost adjusted for
the amortization of premiums and accretion of discounts, which are recognized as
adjustments to interest income.

Securities to be held for indefinite periods of time are classified as
available-for-sale and are carried at fair value with unrealized gains and
losses reported as a separate component of stockholders' equity, net of
estimated income taxes.

Securities that are bought and held principally for the purpose of selling are
classified as trading and reported at fair value, with unrealized gains and
losses included in earnings. The Bank does not hold any investment securities
for the purpose of trading.

Gains or losses on the sales of securities are recognized at trade date
utilizing the specific identification method.

Loans receivable and allowance for loan losses

Loans receivable are stated at unpaid principal balance less loans in process,
deferred loan fees, and allowances for loan losses.

Uncollected interest on loans receivable is accrued as earned based on rates
applied to principal amounts outstanding. Recognition of income on the accrual
basis is discontinued when there is sufficient question as to the collectibility
of the interest. In these cases, the interest previously accrued to income is
reversed, and the loans are placed on the cash basis.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Loans receivable and allowance for loan losses

Loan origination fees and certain direct loan origination costs are being
deferred and the net amount amortized on a level-yield basis as an adjustment to
the related loan yield over its contractual life. Unamortized net fees are
recognized upon early repayment of the loans.

The allowance for loan losses is established by a provision charged to earnings
and is maintained at a level considered adequate to provide for potential loan
losses based on management's evaluation of known and inherent risks in the loan
portfolio. When a loan or portion of a loan is considered uncollectible, it is
charged against the allowance for loan losses. Recoveries of loans previously
charged-off are credited to the allowance when collected.

Management makes regular evaluations of the loan portfolio to determine the
adequacy of the level of the allowance for loan losses. Numerous factors are
considered in the evaluation, including a review of certain borrowers' current
financial status and credit standing, available collateral, loss experience in
relation to outstanding loans, the overall loan portfolio quality, management's
judgement regarding prevailing and anticipated economic conditions, and other
relevant factors.

In addition, various regulatory agencies, as an integral part of their
examination process, periodically review the Bank's allowance for loan losses.
Such agencies may require the Bank to recognize additions to the allowance based
on their judgements about information available to them at the time of their
examination.

The Bank implemented SFAS No. 114, "Accounting by Creditors for Impairment of a
Loan" as amended by SFAS No. 118 during 1996. These statements require some loan
impairments to be measured using a present value of expected cash flows. The
adoption of SFAS No. 114 and No. 118 did not have any material effects on the
Bank's financial position or results of operations.

Loans held-for-sale

Mortgage loans originated and intended for sale in the secondary market are
carried at the lower of cost or estimated fair value in the aggregate.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Foreclosed real estate

Real estate properties acquired through loan foreclosure and other partial or
total satisfaction of problem loans are carried at the lower of fair value or
the related loan balance at the date of foreclosure. Valuations are periodically
performed by management and an allowance for losses is established if the
carrying value of a property subsequently exceeds its fair value less estimated
disposal costs. Losses arising at the time of acquisition of such properties are
charged against the allowance for loan losses. Subsequent write-downs in the
carrying value and expenses incurred to maintain the properties are charged to
expense.

Premises and equipment

Premises and equipment are stated at cost less accumulated depreciation computed
on the straight-line method at rates based on estimated useful lives.

Expenditures for replacements or major improvements are capitalized.
Expenditures for normal maintenance and repairs are charged to expense as
incurred. Upon the sale or retirement of premises and equipment, the cost and
accumulated depreciation are removed from the respective accounts and any gain
or loss is included in income.

Computation of fair values

The calculation of fair value estimates of financial instruments is dependent
upon certain subjective assumptions and involves significant uncertainties.
Changes in assumptions could significantly affect the estimates. These estimates
do not reflect any possible tax ramifications, estimated transaction costs or
any premium or discount that could result from offering the Bank's entire
holdings of a particular financial instrument.

The following methods and assumptions were utilized by the Bank in estimating
the fair values of its on-balance sheet financial instruments at September 30,
1997 and 1996:

Cash and cash equivalents - The carrying amounts reported in the statement of
financial condition approximate these assets' fair value.

Investment securities - Fair values for investment securities are based on
quoted market prices where available. If quoted market prices are not available,
fair values are based on market prices for comparable instruments.

Stock in Federal Home Loan Bank of Boston - Fair value approximates the carrying
amount. If redeemed, the Bank will receive an amount equal to the par value of
the stock.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Computation of fair values - (Continued)

Loans receivable - For variable rate loans that reprice frequently and without
significant change in credit risk, fair values are based on carrying values. The
fair value of other loans are estimated using discounted cash flow analyses
using interest rates currently being offered for loans with similar terms to
borrowers of similar credit quality. The fair value of nonaccrual loans was
estimated using the estimated fair values of the underlying collateral.

Accrued income receivable - The carrying value of accrued income receivable
approximates fair value.

Deposits liabilities - The fair values of non-interest-bearing demand and
savings deposits are, by definition, equal to the amount payable on demand at
the reporting date, i.e., their carrying amounts. Fair values for time
certificates of deposit are estimated using a discounted cash flow technique
that applies interest rates currently being offered to a schedule of aggregated
expected monthly maturities on time deposits.

Advances from Federal Home Loan Bank of Boston - Fair values are estimated using
discounted cash flow analyses based on the Bank's current incremental borrowing
rates for similar types of borrowing arrangements.

Income taxes

The Bank accounts for certain income and expense items differently for financial
reporting purposes than for income tax purposes. Provisions for deferred taxes
are being made in recognition of these temporary differences.

Deferred income taxes reflect the impact of "temporary differences" between the
amount of assets and liabilities for financial reporting purposes and such
amounts as measured by tax laws and regulations. Deferred income taxes result
primarily from the Corporation's practice of preparing income tax returns on the
cash basis of accounting while the financial statements are prepared on the
accrual basis of accounting. Other items are loan fee recognition and
depreciation expense.

The Corporation's accounting policies require a valuation allowance against
deferred tax assets if, based on the weight of available evidence, it is more
likely than not, that some or all of the deferred tax assets will not be
realized. The Corporation believes that all deferred tax assets will be realized
in the future and that no valuation allowance is necessary.

8. STOCKHOLDERS' EQUITY

Cargill Bancorp has 750,000 shares of $.01 par value common stock authorized.
Additionally, 250,000 shares of no-par value preferred stock is authorized, of
which none is issued and outstanding at September 30, 1997.

Retained earnings at September 30, 1997 include $458,000 which is set aside in
accordance with existing provisions of the Internal Revenue Code to absorb
losses on loans. If in the future this amount were used for any other purposes,
a tax liability could be incurred. It is not anticipated that such amount will
be made available for dividends or that a tax thereon will be imposed.

8. STOCKHOLDERS' EQUITY

Prior to its acquisition by the Corporation, the Bank converted from a state
chartered mutual savings and loan association to a state chartered stock savings
and loan association. At the time of conversion, the Bank established a
liquidation account in an amount equal to the Bank's net worth. In the event of
a complete liquidation of the Bank (and only in such event) each eligible
account holder will be entitled to receive a liquidation distribution from the
liquidation account before any liquidation distribution may be made with respect
to capital stock. The balance in the liquidation account at September 30, 1997
was $107,000.

The Bank may not declare or pay a cash dividend on or purchase any of its stock
if the effect would be to reduce the net worth of the Bank below either the
amount of the liquidation account or the capital requirements of its regulators.


9. REGULATORY MATTERS

Regulatory Capital

The Bank is subject to various regulatory capital requirements administered by
the federal banking agencies. Failure to meet minimum capital requirements can
initiate certain mandatory--and possibly additional discretionary--actions by
regulators that, if undertaken, could have a direct material effect on the
Bank's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Bank must meet specific
capital guidelines that involve quantitative measures of the Bank's assets,
liabilities, certain off-balance-sheet items as calculated under regulatory
accounting practices. The Bank's capital amounts and classification are also
subject to qualitative judgments by the regulators about components, risk
weighting, and other factors.

Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier I capital (as defined in the regulations) to
risk-weighted assets (as defined), and of Tier I capital (as defined) to average
assets (as defined). Management believes, as of September 30, 1997, that the
Bank meets all capital adequacy requirements to which it is subject.

As of September 30, 1997, the most recent notification from the Office of Thrift
Supervision categorized the Bank as well capitalized under the regulatory
framework for prompt corrective action. To be categorized as well capitalized
the Bank must maintain minimum total risk-based, Tier I risk based, Tier I
leverage and tangible equity ratios as set forth in the table. There are no
conditions or events since that notification that management believes have
changed the institution's category.

9. REGULATORY MATTERS

Recapitalization of Deposit Insurance Fund

         The Bank is a member of the Savings Association Insurance Fund or
"SAIF". The SAIF was established by the Federal Deposit Insurance Corporation to
insure the depositors of member savings associations and to finance the
resolution of failed institutions. Prior to 1997, the SAIF was undercapitalized
and Congress passed legislation to recapitalize the SAIF through a special
one-time assessment on the assessable deposits of member institutions. As a
result on September 30, 1996, the date the legislation was enacted, the Bank
recorded additional expense of $272,000.


10. STOCK OPTIONS

         Cargill Bancorp, Inc. has stock option plans that provide for the
granting of options to officers, key employees and directors to purchase common
stock of the Corporation at a price not less than the fair market value of the
Corporation's stock on the date of grant. Options under the plans that have not
been issued totaled 7,104. Options that are fully vested and exercisable, were
as follows:

11. RETIREMENT PLANS

         The Bank participates in a multi-employer defined benefit pension plan
covering substantially all employees who qualify as to age and length of
service. Prior to 1995, the Bank had a defined benefit plan which has been
terminated. Total pension expense was $3,064 and $12,511 in the year ended
September 30, 1997 and 1995, respectively. There was no expense during 1996.

12. FINANCIAL INSTRUMENTS

Prior to 1996, the Holding Company provided an Employee Stock Ownership Plan
(ESOP) with 401(k) provisions. Contributions to the ESOP and the shares
purchased by the ESOP were allocated to the participants on the basis of
compensation. Participants become fully vested after completion of seven years
of service. The Bank made contributions to employee accounts by matching 25% of
the participant's elected salary deferral up to a maximum of 4% of salary.
Participating employees are fully vested in both their salary deferral and any
employer matching contributions. The ESOP portion of the 401(k) plan described
above was terminated as of September 30, 1995. The Bank is currently reviewing
the remaining plan.

The Bank is party to financial instruments with off-balance sheet risk in the
normal course of business to meet the financing needs of its customers. These
financial instruments include commitments to extend credit. These commitments
involve, to varying degrees, elements of credit and interest rate risk in excess
of the amount recognized in the balance sheet.

The contractual amounts of outstanding commitments as of September 30, 1997 and
1996 were as follows:



  (Dollars in thousands)                1997            1996
                                        ----            ----

Loan commitments                          76             479


The Bank's exposure to credit loss in the event of nonperformance by the other
party to the financial instrument for commitments to extend credit is
represented by the contractual amount of those instruments. The Bank uses the
same credit policies in making commitments and conditional obligations as it
does for on-balance sheet instruments.

Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract. Commitments
are principally collateralized by mortgages on real estate, generally have fixed
expiration dates or other termination clauses and may require payment of fees.
Since commitments may expire without being drawn upon, the total commitment
amounts do not necessarily represent future cash requirements.

The Bank evaluates each customer's creditworthiness on a case-by-case basis. The
amount of collateral obtained if deemed necessary by the Bank upon extension of
credit is based on management's credit evaluation of the counterparty.
Collateral held is primarily residential property.

Management does not anticipate any material losses as a result of these
commitments.

13.  INCOME PER SHARE

As discussed in Note 14, the Corporation adopted SFAS No. 128, "Earnings Per
Share" which was effective for financial statements issued for periods ending
after December 15, 1997 but requires the retroactive restatement of prior years'
earnings per share amounts. The statement establishes standards for the
computation and presentation of earnings per share (EPS). It simplifies the
computation of EPS by replacing the presentation of primary EPS with a
presentation of basic EPS. The statement also requires the dual presentation of
basic and diluted EPS on the face of the income statement. Diluted EPS is
computed similarly to fully diluted EPS pursuant to APB Opinion No. 15, the
prior practice.

14.  SUBSEQUENT EVENTS

The Corporation issued a 5% stock dividend on January 26, 1998. Accordingly, all
per share data and stock options outstanding are adjusted to reflect the effect
of the stock dividend.

Also, the Corporation adopted Statement of Financial Accounting Standards, SFAS
No. 128 which was effective for financial statements issued for periods ending
after December 15, 1997. The effect of this standard is discussed in Note 13.

NOTE A - GENERAL INFORMATION

      Cargill Bancorp, Inc. ("Cargill") is a savings and loan holding company
for Cargill Bank (the "Bank"). Substantially all operating income and net income
of Cargill are presently accounted for by the Bank.


NOTE B - CURRENT OPERATING ENVIRONMENT

      Cargill Bank operates three offices in Putnam, Thompson, and Woodstock,
Connecticut. A full range of personal banking services are furnished to
individuals, and small businesses. The Bank's primary source of revenue is
derived from providing loans to customers, predominately located in Northeastern
Connecticut.

The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
imposes significant regulatory restrictions and requirements on thrift
institutions insured by the FDIC and their holding companies. FDICIA established
capital categories into which financial institutions are placed based on capital
level. Each capital category establishes different degrees of regulatory
restrictions which can apply to a financial institution. As of June 30, 1998,
the Bank's capital was at a level that placed the Bank in the "well capitalized"
category as defined by FDICIA.


NOTE C - MERGER AGREEMENT WITH WESTBANK CORPORATION

      On July 15, 1998, Cargill entered into an agreement with Westbank
Corporation ("Westbank"), whereby Westbank will acquire the outstanding stock of
Cargill Bancorp, Inc.

Under the terms of the agreement, Cargill will be merged into Westbank. Each
share of Cargill Bancorp common stock will be exchanged for 1.3008 shares of
Westbank common stock, provided that the average closing price of Westbank's
common stock during the 20-day pricing period ending five days before the last
regulatory approval is obtained is greater than or equal to $13.07. If
Westbank's average closing price is less than $13.07 but greater than or equal
to $12.00, then Cargill Bancorp shareholders will received shares of Westbank
common stock having a value of $17.00 per share. Cargill Bancorp has certain
rights to terminate the agreement if Westbank's average closing price is below
$12.00 per share unless Westbank agrees to deliver shares of Westbank common
stock having a value of $17.00 in exchange for each share of Cargill Bancorp
common stock.

The merger is subject to approval of Cargill's shareholders and the receipt of
regulatory approval.

NOTE D - BASIS OF PRESENTATION

      The accompanying unaudited condensed consolidated financial statements for
the nine months ended June 30, 1998 and 1997 have been prepared in accordance
with generally accepted accounting principles for interim information and with
instructions for Form 10-Q. Accordingly, they do not include all of the
information and notes required by generally accepted accounting principles for
complete financial statements. In the opinion of management, all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
presentation have been included. Operating results for the nine month period
ended June 30, 1998, are not necessarily indicative of the results that may be
expected for the year ending September 30, 1998.

For further information, please refer to the Cargill Bancorp's Consolidated
Financial Statements and footnotes thereto for the year ended September 30,
1997.


NOTE E - COMMITMENTS AND CONTINGENT LIABILITIES

      In the normal course of business, there are outstanding commitments and
contingent liabilities, such as commitments to extend credit and undisbursed
balances of construction loans. As of June 30, 1998 loan commitments were
$700,000 and undisbursed balances of construction loans were $106,000.


NOTE F - STOCKHOLDERS' EQUITY

      The Bank is subject to leverage capital ratio requirements as established
by its Federal regulator, the Office of Thrift Supervision ("OTS"). The Bank's
leverage capital ratio as of June 30, 1998 and September 30, 1997 was 6.96% and
6.30%, respectively. In addition, the OTS has established risk-based capital
requirements for insured institutions of 4.00% Tier 1 risk-based capital and
8.00% total risk-based capital. The Bank's risk-based capital at June 30, 1998,
Tier 1 was 14.08% and total risk-based capital was 15.09%, which meets the OTS's
criteria for a well-capitalized financial institution.

                      DESCRIPTION OF WESTBANK CAPITAL STOCK

   
      As of October 30, 1998, the capital stock of Westbank consisted of
9,000,000 authorized shares, par value $2.00 per share, of which 3,797,774
shares of Westbank Common Stock were issued and outstanding (exclusive of
treasury shares), and 100,000 authorized shares, par value $5.00 per share of
Westbank preferred stock, none of which are outstanding. Westbank Common Stock
is traded on the NASDAQ National Market System under the trading symbol "WBKC."
Shares of Westbank Common Stock may be issued from time to time, in such amount
and proportions and for such consideration as may be fixed by the Westbank
Board. No holder of Westbank Common Stock has any preemptive or preferential
right to purchase or to subscribe for any shares of capital stock or other
securities which may be issued by Westbank. Westbank Common Stock has no
redemption or sinking fund provisions applicable thereto and has no conversion
rights.
    

      The outstanding shares of Westbank Common Stock are fully paid and
nonassessable.

      LIQUIDATION. In the event of any liquidation, dissolution or winding up of
Westbank, whether voluntary or involuntary, the holders of Westbank Common Stock
are entitled to receive, on a share-for-share basis, any assets or funds of
Westbank which are distributable to the holders of Westbank Common Stock upon
such events, subject to the prior rights of creditors of Westbank and the
holders of outstanding shares of Westbank preferred stock, if any.

      VOTING. The holders of Westbank Common Stock are entitled to one vote for
each share in all matters voted upon by the shareholders of Westbank. The shares
of Westbank Common Stock do not have cumulative voting rights; consequently, the
holders of a majority in interest of Westbank Common Stock can conceivably elect
all of the directors of Westbank and, in such event, the holders of the
remaining shares voting for election of directors would not be able to elect any
person or persons to the Westbank Board.

      DIVIDENDS. When and if dividends, payable as cash, stock or other
property, are declared by the Westbank Board out of funds legally available
therefor, the holders of Westbank Common Stock are entitled to share equally,
share for share, in such dividends.

      The Federal Reserve Board has authority to prohibit bank holding companies
from paying dividends if such payment would constitute an unsafe or unsound
practice. The Federal Reserve Board has indicated generally that it may be an
unsound practice for bank holding companies to pay dividends unless the bank
holding company's net income over the preceding year is sufficient to fund the
dividends and the expected rate of earnings retention is consistent with the
organization's capital needs, asset quality, and overall financial condition.
Westbank's ability to pay dividends is dependent upon the flow of dividend
income to it from its subsidiaries, which may be affected or limited by
regulatory restrictions imposed by federal or state bank regulatory agencies. At
June


                                      -97-
   136
30, 1998, Park West Bank had available approximately $4,000,000 for payment of
dividends to Westbank under applicable Massachusetts statutory limitations.

      PREFERRED STOCK PURCHASE RIGHTS. On November 19, 1997, the Board of
Directors of Westbank adopted an Amended and Restated Shareholder Rights
Agreement (the "Rights Agreement"). The following description of the terms of
the Rights Agreement does not purport to be complete and is qualified in its
entirety by reference to the Rights Agreement. See "WHERE YOU CAN FIND MORE
INFORMATION" and "INFORMATION INCORPORATED BY REFERENCE."

      Pursuant to the terms of the Rights Agreement, the Board of Directors
declared a dividend distribution of one Preferred Stock Purchase Right (a
"Right") for each outstanding share of Common Stock of Westbank to stockholders
of record as of the close of business on December 3, 1997 (the "December 3, 1997
Record Date"). In addition, one Right will automatically attach to each share
of Westbank Common Stock issued between the December 3, 1997 Record Date and the
Distribution Date (as hereinafter defined). Each Right entitles the registered
holder thereof to purchase from Westbank a unit consisting of one ten-thousandth
of a share (a Unit) of Series A Junior Participating Cumulative Preferred
Stock, par value $5.00 per share (the Preferred Stock), at a cash exercise
price of $60.00 per Unit (the Exercise Price), subject to adjustment.

      Initially, the Rights are not exercisable and are attached to and trade
with all outstanding shares of Westbank Common Stock outstanding as of, and
issued subsequent to, the December 3, 1997 Record Date. The Rights will separate
from the Westbank Common Stock and will become exercisable upon the earliest of
(i) the close of business on the tenth calendar day following the first public
announcement that a person or group of affiliated or associated persons has
acquired beneficial ownership of 15% or more of the outstanding shares of
Westbank Common Stock (an Acquiring Person) (the date of said announcement
being referred to as the Stock Acquisition Date), (ii) the close of business on
the tenth business day (or such other day as the Board of Directors may
determine) following the commencement of a tender offer or exchange offer that
would result upon its consummation in a person or group becoming the beneficial
owner of 15% or more of the outstanding shares of Westbank Common Stock or (iii)
the determination by the Board of Directors that any person is an Adverse Person
(the earliest of such dates being herein referred to as the Distribution Date).

   
      The Board of Directors may declare a person to be an Adverse Person after
a determination that such person, alone or together with its affiliates and
associates, has become the beneficial owner of 10% or more of the outstanding
shares of Westbank Common Stock and a determination by the Board of Directors,
after reasonable inquiry and investigation, including such consultation, if any,
with such persons as the directors shall deem appropriate, that (a) such
beneficial ownership by such person is intended to cause, is reasonably likely
to cause or will cause Westbank to repurchase the Westbank Common Stock
beneficially owned by such person or to cause pressure on Westbank to take
action or enter into a transaction or series of transactions which would provide
such person with short-term financial gain under circumstances where the Board
of Directors determines that the best long-term interests of Westbank and its
shareholders, but for the actions and possible actions of such person, would not
be served by taking such action or entering into such transaction or series of
transactions at that time or (b) such beneficial ownership is causing, or is
reasonably likely to cause, a material adverse impact (including, but not
limited to, impairment of relationships with customers or impairment of Westbank
ability to maintain its competitive position) on the business or prospects of
Westbank. No delay or failure by the Board of Directors
    


                                      -98-
   137
   
to declare a person to be an Adverse Person shall in any way waive or otherwise
affect the power of the Board of Directors subsequently to declare a person an
Adverse Person. In the event that the Board of Directors should at any time
determine, upon reasonable inquiry and investigation, including consultation
with such persons as the Board of Directors shall deem appropriate, that such
person has not met or complied with any condition specified by the Board of
Directors, the Board of Directors may at any time thereafter declare the person
to be an Adverse Person.
    

      Until the Distribution Date (or earlier redemption, exchange or expiration
of the Rights), (a) the Rights will be evidenced by the Westbank Common Stock
certificates and will be transferred with and only with such Westbank Common
Stock certificates, (b) new Westbank Common Stock certificates issued after the
December 3, 1997 Record Date will contain a notation incorporating the Rights
Agreement by reference, and (c) the surrender for transfer of any certificates
for common stock will also constitute the transfer of the Rights associated with
the Westbank Common Stock represented by such certificate.

      The Rights are not exercisable until the Distribution Date and will expire
at the close of business on November 19, 2007, unless previously redeemed or
exchanged by Westbank as described below.

      As soon as practicable after the Distribution Date, Right Certificates
will be mailed to holders of record of Westbank Common Stock as of the close of
business on the Distribution Date and, thereafter, the separate Right
Certificates alone will represent the Rights. Except as otherwise determined by
the Board of Directors, only shares of Westbank Common Stock issued prior to the
Distribution Date will be issued with Rights.

      In the event that a Stock Acquisition Date occurs or the Board of
Directors determines that a person is an Adverse Person, proper provision will
be made so that each holder of a Right (other than an Acquiring Person, an
Adverse Person or their associates or affiliates, whose Rights shall become null
and void) will thereafter have the right to receive upon exercise that number of
Units of Preferred Stock of Westbank having a market value of two times the
exercise price of the Right (such right being referred to as the Subscription
Right).

   
      In the event that, at any time following the Stock Acquisition Date, (i)
the Company consolidates with, or merges with and into, any other person, and
Westbank is not the continuing or surviving corporation, (ii) any person
consolidates with the Company, or merges with and into Westbank and Westbank is
the continuing or surviving corporation of such merger and, in connection with
such merger, all or part of the shares of Westbank Common Stock are changed into
or exchanged for stock or other securities of any other person or cash or any
other property, or (iii) 50% or more of Westbank's assets or earning power is
sold, mortgaged or otherwise transferred, each holder of a Right shall
thereafter have the right to receive, upon exercise, Westbank Common Stock of
the acquiring company having a market value equal to two times the exercise
price of the Right (such right being referred to as the Merger Right). The
holder of a Right will continue to have the Merger Right whether or not such
holder has exercised the Subscription Right. Rights that are or were
beneficially owned by an Acquiring Person or an Adverse Person may (under
certain circumstances specified in the Rights Agreement) become null and void.

      At any time after the Stock Acquisition Date occurs or the Board of
Directors determines that a person is an Adverse Person, the Board of Directors
may, at its option, exchange all or any part
    


                                      -99-
   138
   
of the then outstanding and exercisable Rights for shares of Westbank Common
Stock or Units of Preferred Stock at an exchange ratio of one share of Westbank
Common Stock or one Unit of Preferred Stock per Right.
    

      Notwithstanding the foregoing, the Board of Directors generally will not
be empowered to effect such exchange at any time after any person becomes the
beneficial owner of 50% or more of the Westbank Common Stock.

      The Exercise Price payable, and the number of Units of Preferred Stock or
other securities or property issuable, upon exercise of the Rights are subject
to adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Stock, (ii) if holders of the Preferred Stock are granted certain rights or
warrants to subscribe for Preferred Stock or convertible securities at less than
the current market price of the Preferred Stock, or (iii) upon the distribution
to holders of the Preferred Stock of evidences of indebtedness or assets
(excluding regular quarterly cash dividends) or of subscription rights or
warrants (other than those referred to above).

      With certain exceptions, no adjustment in the Exercise Price will be
required until cumulative adjustments amount to at least 1% of the Exercise
Price. The Company is not obligated to issue fractional Units. If Westbank
elects not to issue fractional Units, in lieu thereof an adjustment in cash will
be made based on the fair market value of the Preferred Stock on the last
trading date prior to the date of exercise. Any of the provisions of the Rights
Agreement may be amended by the Board of Directors of Westbank at any time prior
to the Distribution Date.

      The Rights may be redeemed in whole, but not in part, at a price of $0.001
per Right (payable in cash, Westbank Common Stock or other consideration deemed
appropriate by the Board of Directors) by the Board of Directors only until the
earliest of (i) the date on which a person is declared to be an Adverse Person,
(ii) the close of business on the tenth calendar day after the Stock Acquisition
Date, or (iii) the expiration date of the Rights Agreement. Immediately upon the
action of the Board of Directors ordering redemption of the Rights, the Rights
will terminate and thereafter the only right of the holders of Rights will be to
receive the redemption price.

      The Rights Agreement may be amended by the Board of Directors in its sole
discretion until the Distribution Date. After the Distribution Date, the Board
of Directors may, subject to certain limitations set forth in the Rights
Agreement, amend the Rights Agreement only to cure any ambiguity, defect or
inconsistency, to shorten or lengthen any time period, or to make changes that
do not adversely affect the interests of Rights holders (excluding the interests
of an Acquiring Person, an Adverse Person or their associates or affiliates). In
addition, the Board of Directors may at any time prior to such time as any
person becomes an Acquiring Person amend the Rights Agreement to lower the
threshold at which a person becomes an Acquiring Person to not less than the
greater of (i) the sum of .001% and the largest percentage of the outstanding
Westbank Common Stock then owned by any person and (ii) 10%.

      Until a Right is exercised, the holder will have no rights as a
stockholder of Westbank (beyond those as an existing shareholder), including the
right to vote or to receive dividends. While the distribution of the Rights will
not be taxable to shareholders or to Westbank, shareholders may, depending upon
the circumstances, recognize taxable income in the event that the Rights become


                                     -100-
   139
exercisable for Units, other securities of Westbank, other consideration or for
Westbank Common Stock of an acquiring company.

      PREFERRED STOCK. Under the Westbank Articles, the Westbank Board is
authorized, without further shareholder action, to provide for the issuance of
the Westbank Preferred Stock, in one or more series, with such designations,
dividend rates, special or relative rights in the event of liquidation,
distribution or sale of assets or dissolution or winding up of Westbank, sinking
fund provisions, redemption or purchase account provisions, conversion
provisions, and voting rights as shall be set forth as and when established by
the Westbank Board.

                 COMPARISON OF THE RIGHTS OF HOLDERS OF WESTBANK
   
                     COMMON STOCK AND CARGILL COMMON STOCK
    

      At the Effective Time, the shareholders of Cargill, except those
shareholders exercising dissenters' rights, will become shareholders of
Westbank. As shareholders of Cargill, their rights are presently governed by
Delaware law and the Cargill Certificate of Incorporation (the "Cargill
Certificate") and the Cargill Bylaws (the "Cargill Bylaws"). As shareholders of
Westbank, their rights will be governed by Massachusetts law, the Westbank
Articles and the Westbank Bylaws (the "Westbank Bylaws"). The following
discussion summarizes the material differences between the rights of holders of
Cargill Common Stock and holders of Westbank Common Stock and differences
between the charters and bylaws of Cargill and Westbank. This summary does not
purport to be complete and is qualified in its entirety by reference to the
Cargill Certificate, the Cargill Bylaws, the Westbank Articles and the Westbank
Bylaws and the relevant provisions of Delaware and Massachusetts law.

SPECIAL MEETINGS OF SHAREHOLDERS

      CARGILL. Delaware law provides that special meetings of shareholders may
be called by the board of directors or by such person or persons as may be
authorized by the corporation's certificate of incorporation or bylaws. The
Cargill Bylaws provide that special meetings may only be called by the President
of Cargill, or a majority of the Board of Directors of Cargill.

      WESTBANK. Massachusetts law provides that special meetings of shareholders
may be called by the president or the directors or upon written application to
the clerk of the corporation by the holders of at least 10% of all shares
entitled to vote at the meeting, provided that, unless otherwise provided in its
articles of organization or bylaws, a corporation with a class of voting stock
registered pursuant to the Exchange Act need not hold such meeting except upon
the demand of holders of not less than 40% of such shares.

      The Westbank Bylaws provide that Westbank's Board may call special
meetings of shareholders. Moreover, the Westbank Bylaws provide that special
meetings shall be called by the clerk of Westbank upon written application of
shareholders holding at least 662/3% in interest of the capital stock entitled
to vote at the meeting or such lesser percentage permitted at law.

INSPECTION RIGHTS

      CARGILL. Under Delaware law, shareholders have the right to inspect the
corporation's stock ledger, stockholder list and other books and records upon
the demonstration of a proper purpose. 

                                      -101-
   140
Directors have the right to examine the corporation's stock ledger, list of
stockholders, and other books and records for any purpose reasonably related to
their position.

      WESTBANK. Under Massachusetts law, shareholders have the right to inspect
a corporation's articles of organization, bylaws, records of incorporators' and
shareholders' meetings upon the demonstration of a proper purpose.

ACTION BY CONSENT OF SHAREHOLDERS

      CARGILL. Under Delaware law, unless the certificate of incorporation
provides otherwise, any action required or permitted at a meeting may be taken
without a meeting, without notice, or vote, if written consent is signed by the
holders of outstanding stock having not less than the minimum number of votes
that would be necessary to authorize such action at a meeting. The Cargill
Certificate does not contain a provision regarding action by consent of
shareholders.

      WESTBANK. Under Massachusetts law, unless the articles of organization
provide otherwise, any action to be taken by shareholders may be taken without a
meeting, without prior notice, and without a vote, if the shareholders consent
unanimously in writing to the action. The Westbank Bylaws provide that any
action required or permitted to be taken by shareholders may be effected by a
unanimous consent in writing.

PREEMPTIVE RIGHTS

      CARGILL. Under Delaware law, shareholders do not generally have a
preemptive right to acquire the corporation's unissued shares except to the
extent provided in its certificate of incorporation. The Cargill Certificate
provides that shareholders do not have preemptive rights.

      WESTBANK. Unless otherwise provided in the corporation's articles,
Massachusetts law does not grant any preemptive rights. The Westbank Articles
provide that shareholders do not have preemptive rights.

DIVIDENDS AND REPURCHASES OF STOCK

      CARGILL. Under Delaware law, a corporation may, unless otherwise
restricted by its certificate of incorporation, pay dividends in cash, property
or shares of capital stock out of surplus or, if no surplus exists, out of net
profits for the fiscal year in which declared or out of net profits for the
preceding fiscal year (provided that such payment will not reduce capital below
the amount of capital represented by classes of stock having a preference upon
distribution of assets).

      Under Delaware law, a corporation may repurchase or redeem its shares only
out of surplus and only if such purchase does not impair capital. However, a
corporation may redeem preferred stock out of capital if such shares will be
retired upon redemption and the stated capital of the corporation is thereupon
reduced in accordance with Delaware law.

      WESTBANK. Under Massachusetts law, the payment of dividends and the
redemption or repurchase of a corporation's stock are generally permissible, if
such actions do not violate the corporation's articles of organization, provided
that the corporation is not insolvent or rendered 

                                     -102-
   141
insolvent by the action.

CLASSIFICATION OF THE BOARD OF DIRECTORS

      CARGILL. Under Delaware law, a corporation's certificate of incorporation
may provide for staggering the terms of directors by dividing the total number
of directors into one, two or three groups, with each group containing
approximately the same percentage of the total, as near as may be. The Cargill
Certificate provides for such staggering and the Cargill Board is divided into
three classes.

      WESTBANK. Massachusetts law requires classification of the board of
directors of any Massachusetts corporation having a class of voting stock
registered under the Exchange Act, as does Westbank, into three classes, unless
the corporation has affirmatively elected in accordance with the applicable
statutory requirements to be exempt from such statutory director classification
requirement. Westbank has made no such election, and, to the contrary, the
Westbank Articles provide that the Westbank Board is to be divided into three
classes, with the directors in each class being elected for staggered three-year
terms.

REMOVAL OF DIRECTORS

      CARGILL. Under Delaware law, unless the certificate of incorporation
provides otherwise, in the case of a corporation whose board is classified,
shareholders may remove a director only for cause. The Cargill Certificate does
not address removal of directors. The Cargill Bylaws provide that directors may
be removed for cause and then only by an affirmative vote of a majority of the
total votes eligible to be cast by shareholders at a meeting called expressly
for that purpose.

      WESTBANK. Under Massachusetts law, unless the articles of organization or
bylaws provide otherwise, shareholders may by a majority vote generally remove
directors with or without cause and directors may by a majority vote generally
remove directors for cause. The Westbank Bylaws
provide that, any director may be removed from office with or without cause by
majority of directors in office.

VACANCIES ON THE BOARD OF DIRECTORS

      CARGILL. Under Delaware law, unless the certificate of incorporation
provides otherwise, vacancies on the board of directors, including a vacancy
resulting from an increase in the number of directors, may be filled by a
majority of the remaining directors. If the directors remaining in office
constitute less than a quorum of the board of directors, they may fill the
vacancy by the affirmative vote of a majority of the remaining directors. The
Cargill Bylaws provide that vacancies created by an increase in the number of
directors shall be filled, for the unexpired term, by the concurring vote of a
majority of directors then in office, whether or not a quorum, and any director
so chosen shall hold office for the remainder of the term until their successor
is elected or purified.

      WESTBANK. The Westbank Bylaws permit vacancies (other than a vacancy
caused by the death, resignation or removal of a director elected by preferred
stock shareholders) unless and until 

                                     -103-
   142
filled by the stockholders, may be filled by a majority of the directors present
at any meeting of directors at which a quorum is present.

EXCULPATION OF DIRECTORS

      CARGILL. Under Delaware law, the certificate of incorporation of a
corporation may contain a provision eliminating or limiting the personal
liability of a director to the corporation or its shareholders for monetary
damages for breaches of fiduciary duty except where such exculpation is
expressly prohibited. In Delaware, a director is not exculpated from liability
under provisions of Delaware law relating to unlawful stock purchases or
redemptions. In addition, this limitation cannot apply to liability of a
director (1) for any breach of the director's duty of loyalty to the corporation
or its shareholders; (2) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law; or (3) for any transaction
from which the director derived an improper personal benefit. The Cargill
Certificate does not contain such a provision.

      WESTBANK. Massachusetts law permits, and the Westbank Articles provide,
that no director shall be personally liable to Westbank or its shareholders for
monetary damages for breaches of fiduciary duty except where such exculpation is
expressly prohibited. In Massachusetts, a director is not exculpated from
liability under provisions of Massachusetts law relating to unlawful payments of
dividends and unlawful stock purchases or redemptions. In addition, the Westbank
Articles provide that the this limitation cannot apply to liability of a
director (i) for breach of the director's duty of loyalty to the corporation or
its shareholders, (ii) for acts and omissions not in good faith or which involve
intentional misconduct or knowing violation of law; or (iii) for any transaction
from which the director derived an improper personal benefit.

INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHERS

      Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of Westbank,
Westbank has been advised that in the opinion of the SEC such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by Westbank in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, Westbank will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

      CARGILL. Under Delaware law, a corporation may indemnify a director,
officer, employee or agent against liability if that person conducted himself in
good faith and with the reasonable belief that his conduct in his official
capacity with the corporation was in the best interests of the corporation or
that his conduct in any other case was not opposed to its best interests. The
Cargill Bylaws provide that each person made or threatened to be made a party in
any proceeding by reason of the fact that he or she was a director, officer,
employee or agent of Cargill shall be indemnified and held harmless by Cargill
against all expense, liability and loss reasonably incurred by such indemnitee
in connection with such proceeding, provided that such indemnitee shall have
acted in good faith in the reasonable belief that such action was in, or not
opposed to, the best interests of Cargill.


                                     -104-
   143
      WESTBANK. Massachusetts law generally permits indemnification of directors
and officers for expenses incurred by them by reason of their position with the
corporation, if the director or officer has acted in good faith and with the
reasonable belief that his conduct was in the best interests of the corporation.
The Westbank Bylaws provide that each person made a party in any proceeding by
reason of the fact that he or she was a director, officer, employee or agent of
Westbank shall be indemnified by Westbank against all expense and liability
reasonably incurred by such indemnitee in connection with such proceeding,
provided that such indemnitee shall undertake to repay such payment if he shall
be adjudicated to be not entitled to indemnification.

MERGERS, SHARE EXCHANGES OR ASSET SALES; ANTI-TAKEOVER PROVISIONS OF STATE LAW

      CARGILL. Delaware law generally requires that any merger, consolidation,
or sale of substantially all the assets of a corporation be approved by a vote
of the holders of a majority of all outstanding shares entitled to vote thereon.

      The Cargill Certificate provides that any Business Combination (as defined
below) involving Cargill and an Interested Shareholder (generally a person
owning 10% or more of Cargill's Common Stock) must be approved by the holders of
at least 75% of the outstanding shares of Cargill's voting stock and the holders
of at least a majority of the voting stock, voting together as a single class,
excluding the number of shares owned or controlled by the Interested Shareholder
(the "Voting Requirement"), at a duly constituted meeting of shareholders called
expressly for such purpose. Such affirmative vote shall be in addition to and
not in lieu of any other vote required under applicable law and is required
notwithstanding the fact that no vote may be required or that a lesser
percentage may be specified by law. The Voting Requirement does not apply and
the affirmative vote of only a majority of Cargill's voting stock is required,
if (i) the Business Combination is approved by an affirmative vote of a majority
of both the continuing directors then in office and (ii) certain "fair price"
and other criteria are met.

      As defined in the Cargill Certificate, a "Business Combination" includes,
among other things (i) any merger or consolidation of Cargill or any subsidiary
with an Interested Shareholder or affiliate thereof, (ii) the sale, lease,
exchange, mortgage, pledge, transfer or other disposition by Cargill of assets
having a fair market value of $1,000,000 or more to or with an Interested
Shareholder or an affiliate thereof, (iii) the issuance or transfer by Cargill
or any subsidiary (in one transaction or a series of transactions) of any
securities of Cargill or any subsidiary to an Interested Shareholder or any
affiliate thereof in exchange for cash, securities or other property (or a
combination thereof) having an aggregate fair market value of $1,000,000 or
more, (iv) the adoption of a plan or proposal for the liquidation or dissolution
of Cargill proposed by or on behalf of an Interested Shareholder or an affiliate
thereof, and (v) any transaction that has the effect, directly or indirectly, of
increasing the proportionate share of any class of equity or convertible
securities of Cargill or any subsidiary that is beneficially owned by an
Interested Shareholder or any affiliate thereof.

      WESTBANK. Massachusetts law requires the approval of the directors and the
vote of the holders of a majority of the outstanding stock entitled to vote
thereon for the merger of the corporation into any other corporation, although
the certificate of incorporation may require a higher shareholder vote.


                                     -105-
   144

      The Westbank Articles provide that any Subject Transaction (as defined
below) involving Westbank and a receiving entity must be approved by the holders
of at least 75% of the outstanding shares of Westbank's voting stock (the
"Voting Requirement") voting together as a single class at a duly constituted
meeting of shareholders called expressly for such purpose.

      As defined in the Westbank Articles, a "Subject Transaction" includes,
among other things (i) any merger or consolidation of Westbank or any subsidiary
with a Receiving Entity, (ii) the sale, lease, exchange, transfer or,
distribution of all or substantially all or a substantial portion of Westbank or
its subsidiaries with a Receiving Entity, (iii) the issuance by Westbank or any
subsidiary of any securities rights, warrants or options of Westbank or any
subsidiary to any stockholder other than by stock dividend declared and paid to
all stockholders established by Westbank, (iv) the adoption of a plan or
proposal for the liquidation or dissolution of Westbank or any subsidiary, and
(v) any transaction that has the effect, directly or indirectly, of increasing
the proportionate share of any class of stock of Westbank or any subsidiary.

      Massachusetts Anti-Takeover Laws. Chapter 110D of the Massachusetts
General Laws covers "control share acquisitions" affecting corporations
incorporated in Massachusetts that have at least 200 shareholders and possess
certain statutory indicia reflecting additional substantial ties to
Massachusetts (as is the case with Westbank). Chapter 110D limits the voting
rights of shares held by persons who have acquired 20% or more of the voting
power of the target corporation. Under this statute, shares acquired in a
control share acquisition retain the same voting rights as all other shares of
the same class or series only to the extent authorized by a vote of the majority
of all shares entitled to vote for the election of directors, excluding such
acquired shares. A corporation that is otherwise subject to Chapter 110D may
expressly provide in its articles of organization or bylaws that the statute
does not apply. Westbank has not included any such "opt out" provision in either
the Westbank Articles or Westbank Bylaws.

      Chapter 110F of the Massachusetts General Laws provides that if any
acquiror buys 5% or more of a target company's stock, where the target company
has at least 200 shareholders and possesses certain statutory indicia reflecting
substantial ties or nexus to Massachusetts (as is the case with Westbank),
without the prior approval of the target company's board of directors, such
acquiror generally may not, for a period of three years, (i) complete the
acquisition of the target company through a merger, (ii) pledge or sell any
assets of the target company or (iii) engage in other self-dealing transactions
with the target company. The prior board of directors approval requirement does
not apply if the acquirer buys at least 90% of the target company's outstanding
stock in the transaction in which it crosses the 5% threshold or if the
acquirer, after crossing the threshold, obtains the approval of the target
company's board of directors and two-thirds of the target company's stock held
by persons other than the acquirer. A corporation that would otherwise be
covered by Chapter 110F may expressly provide in its articles of organization
that the statute does not apply. The Westbank Articles do not contain any such
"opt out" provision.

AMENDMENTS TO CHARTER

      CARGILL. Under Delaware law, amendments to a certificate of incorporation
require the approval of the directors and the vote of the holders of a majority
of the outstanding stock and a majority of each class of stock outstanding and
entitled to vote thereon as a class, unless the 

                                     -106-
   145
certificate of incorporation requires a greater proportion. The Cargill
Certificate provides that no amendment, addition, alteration, change or repeal
of the Cargill Certificate shall be made unless the same is first proposed by
the board of directors and thereafter approved by a majority of shareholders
unless a higher vote is required by the Cargill Certificate or by law.

      WESTBANK. Massachusetts law requires a class vote when, among other
things, an amendment will adversely affect the powers, preferences or special
rights of a class of stock. Pursuant to the Westbank Articles, no amendment,
addition, alteration, change or repeal of the Westbank Articles shall be made,
unless the same is first adopted by the affirmative vote of a majority of the
board of directors of Westbank then in office, and thereafter approved by the
shareholders by not less than two-thirds of the total votes eligible to be cast
at a duly constituted meeting, or, in the case of certain provisions of Article
6 of the Westbank Articles, by not less than seventy five percent (75%) of the
total votes eligible to be cast at a duly constituted meeting.

AMENDMENTS TO BYLAWS

      CARGILL. Delaware law provides that shareholders may amend a corporation's
bylaws unless the certificate of incorporation reserves that power to the
directors of the corporation. The Cargill Bylaws permit the directors to amend
the Cargill Bylaws by a two-thirds vote of the directors in office. The Cargill
Bylaws also permit shareholders to amend the Cargill Bylaws by two-thirds of the
total votes eligible to be cast at a duly constituted meeting.

      WESTBANK. Under Massachusetts law, the power to adopt, amend or repeal
bylaws lies in shareholders entitled to vote; provided, however, that if
authorized by the corporation's articles of organization, the bylaws may confer
the power to adopt, amend or repeal bylaws upon the directors. The Westbank
Bylaws provide that its bylaws may be amended by the affirmative vote of a
majority of the directors unless a higher vote or shareholder vote is required
by law, the Westbank Articles or the Westbank Bylaws. In addition, the Westbank
Bylaws provide that they may be amended by shareholders by two-thirds of the
total votes eligible to be cast at a duly constituted meeting.

DISSENTERS' APPRAISAL RIGHTS

      CARGILL. Generally, Delaware law permits a shareholder to obtain fair
value for his shares in the event of, among others, consummation of a merger to
which the corporation is a party, that requires a shareholder vote, provided
that the shareholder follows the requirements of the Dissenters' Rights Statute.
A shareholder wishing to assert dissenters' rights must deliver to the
corporation, before the vote at the shareholders' meeting pursuant to which
corporate action creating dissenters' rights takes place, written notice of his
intent to demand payment for his shares if the proposed action is taken and such
shareholder must not vote his shares in favor of the proposed action. Failure to
follow both these steps prevents a shareholder from asserting dissenters'
rights. Cargill shareholders may exercise dissenters' rights in connection with
the Merger. See "THE MEETING-- Appraisal Rights and Dissenting Shareholders."

                                     -107-
   146

      WESTBANK. Under Massachusetts law, appraisal rights are available in
connection with certain statutory mergers or consolidations, but are not
available to holders of shares of stock of a corporation which is to be the
surviving corporation if no vote of its shareholders is required to approve the
merger. Because the number of shares to be issued by Westbank to Cargill
shareholders will not exceed fifteen percent (15%) of Westbank's total
outstanding Common Stock immediately prior to the Effective Time, holders of
Westbank Common Stock will not vote on the Merger and therefore do not have
appraisal rights with respect to the Merger.

SHAREHOLDERS RIGHTS PLAN

      CARGILL. Cargill has no shareholders rights plan.

      WESTBANK. Westbank has distributed to each holder of Westbank Common Stock
one Right for each outstanding share of Westbank Common Stock. The Rights
entitle the shareholder to certain rights in the event of certain transactions
involving Westbank. See "DESCRIPTION OF WESTBANK CAPITAL STOCK."

                                  LEGAL MATTERS

      The validity of the shares of Westbank Common Stock to be issued in the
Merger will be passed upon by Cranmore, FitzGerald & Meaney, of Hartford,
Connecticut. Certain legal matters relating to the Merger, including the
tax-free nature of the Merger, will be passed upon, for the parties, by
Cranmore, FitzGerald & Meaney of Hartford, Connecticut and certain legal matters
will be passed upon for Cargill by the law firm of Shipman & Goodwin LLP of
Hartford, CT.

Bank or the holders of any of the shares of Cargill Common Stock (shares of
Cargill Common Stock being hereinafter collectively referred to as "Shares"):

         3.1.1 Each Share issued and outstanding immediately prior to the
Effective Time (other than any Shares to be canceled pursuant to Section 3.1.2
and any Dissenting Shares (as hereinafter defined)) shall be canceled and shall
be converted automatically into and be exchangeable for shares of Westbank
Common Stock in accordance with the Exchange Ratio as set forth below (rounded
to the nearest ten thousandth of a share):

         3.1.1.A As used herein, the term "Westbank Market Value" shall mean the
average of the closing prices of Westbank Common Stock on the Nasdaq National
Market System for each of the twenty (20) consecutive trading days ending on the
fifth trading day before the Determination Date as defined in Section 11.1.7. As
used herein, the term "Exchange Ratio" shall mean the number of shares of
Westbank Common Stock to be received for each share of Cargill Common Stock and
the term "Merger Consideration" shall mean the number of shares of Westbank
Common Stock represented by the Exchange Ratio together with any cash for
fractional shares, as applicable.

         3.1.1.B

         (a)      For purposes of this Merger, the Exchange Ratio shall be:

                  (i) if the Westbank Market Value is greater than or equal to
$13.07, then 1.3008 fully paid and nonassessable shares of Westbank Common
Stock;

                  (ii) If the Westbank Market Value is less than $13.07 but
greater than or equal to $12.00, then the number of fully paid and nonassessable
shares of Westbank Common Stock (rounded to the nearest one ten-thousandth)
obtained by dividing (A) $17.00 per share by (B) the Westbank Market Value; and

                  (iii) if the Westbank Market Value is less than $12.00, then
1.4167 fully paid and non-assessable shares of Westbank Common Stock, subject to
adjustment as provided in Section 11.1.7 of this Agreement.

         (b) In the event that before the Effective Time an announcement is made
with respect to a business combination involving the acquisition of Westbank or
a substantial portion of its assets (a "Westbank Acquisition") by another
company or person, Westbank covenants and agrees that such Westbank Acquisition
shall not be consummated prior to the Merger and the transactions contemplated
by this Agreement.

         3.1.2 Each Share held in the treasury of Cargill and each Share owned
beneficially by Westbank, Park West Bank or by any direct or indirect
consolidated subsidiary of any of them immediately prior to the Effective Time
(other than in a fiduciary capacity) shall be canceled without any conversion
thereof and no payment or distribution shall be made with respect thereto.


                                       -7-

   160



         3.1.3 Each share of Westbank Common Stock issued and outstanding
immediately prior to the Effective Time shall remain an issued and outstanding
share of Westbank Common Stock following the Effective Time

         3.1.4. If the holders of Westbank Common Stock shall have received or
shall have become entitled to receive, without payment therefor, during the
period commencing on the date hereof and ending with the Effective Date,
additional shares of common stock or other securities for their stock by way of
a stock split, stock dividend, reclassification, combination of shares of
similar corporate rearrangement ("Stock Adjustment"), then the amount of
Westbank Common Stock to be exchanged on the Effective Date for Cargill Common
Stock or kind of securities of Westbank shall be proportionately adjusted to
take into account such Stock Adjustment. In addition, the Westbank Market Value
shall be proportionately adjusted to compensate for any such Stock Adjustment.

         3.1.5. Notwithstanding any term or provision hereof, no fractional
shares of Westbank Common Stock, and no certificates or script therefor, or
other evidence of ownership thereof, will be issued in exchange for any shares
of Cargill Common Stock; no dividend or distribution with respect to Westbank
Common Stock shall be payable on or with respect to any fractional share
interests; and no such fractional share interest shall entitle the owner thereof
to vote or to any other rights of a shareholder of Westbank. In lieu of such
fractional share interest, any holder of Cargill Common Stock who would
otherwise be entitled to a fractional share of Westbank Common Stock will, upon
surrender of his certificate or certificates representing Cargill Common Stock
outstanding immediately prior to the Effective Date, be paid the applicable cash
value of such fractional share interest, which shall be equal to the product of
the fraction multiplied by the Westbank Market Value. For the purposes of
determining any such fractional share interests, all shares of Cargill Common
Stock owned by a Cargill shareholder shall be combined so as to calculate the
maximum number of whole shares of Westbank Common Stock issuable to such Cargill
shareholder.

         3.2 EMPLOYEE STOCK OPTIONS. On the Effective Date, each then
outstanding stock option to purchase Cargill Common Stock ("Cargill Stock
Options") pursuant to the stock option plans identified in Cargill Disclosure
Schedules to this Agreement (collectively, the "Cargill Stock Option Plans")
will be assumed by Westbank. Each Cargill Stock Option so assumed by Westbank
under this Agreement shall continue to have, and be subject to, the same terms
and conditions set forth in the Cargill Stock Option Plans immediately prior to
the Effective Date, except that (i) such Cargill Stock Options shall be
exercisable for that number of whole shares of Westbank Common Stock equal to
the product of the number of shares of Cargill Common Stock covered by the
Cargill Stock Option multiplied by the Exchange Ratio, provided that any
fractional share of Westbank Common Stock resulting from such multiplication
shall be rounded up to the nearest share; and (ii) the exercise price per share
of Westbank Common Stock shall be equal to the exercise price per share of
Cargill Common Stock of such Cargill Stock Option, divided by the Exchange
Ratio, provided that such exercise price shall be rounded down to the nearest
cent. It is the intention of the parties that the Cargill Stock Options assumed
by Westbank qualify following the Effective Date as incentive stock options as
defined in Section 422A of the Internal Revenue Code of 1989, as amended to the
extent that the Cargill Stock Options qualified as incentive stock options
immediately prior to the Effective Date. Promptly following the Effective Date,
Westbank shall reserve for issuance such number of shares of Westbank Common
Stock as shall be necessary to be issued pursuant to the exercise of the options
assumed by Westbank pursuant to this Section 3.2, and Westbank shall file a
registration statement on Form S-8 to register the shares of Westbank Common
Stock issuable in connection therewith. Cargill hereby represents and warrants
to Westbank that the maximum number of Shares subject to issuance pursuant to
the exercise of stock options issued and outstanding under the Cargill Stock
Option Plans is not and shall not be at or prior to the Effective Date more than
64,536.

         3.3 DISSENTING SHARES.

         3.3.1 Notwithstanding anything in this Agreement to the contrary and
unless otherwise provided by applicable law, Shares that are issued and
outstanding immediately prior to the Effective Time and that are owned by
stockholders who have properly perfected their rights of appraisal within the
meaning of Title 8 of Section 262 of Delaware General Corporation Law (the
"Dissenting Shares"), shall not be converted into the right to receive the
Merger Consideration, unless and until such stockholders shall have failed to
perfect or shall have effectively withdrawn or lost their right of payment under
applicable law, but, instead, the holders thereof shall be entitled to an
appraisal by the Court of Chancery of the fair value of such Dissenting Shares
in accordance with the provisions of Title 8 of Section 262 of Delaware General
Corporation Law. If any such holder shall have failed to perfect or shall have
effectively withdrawn or lost such right of appraisal, each Share held by such
stockholder shall thereupon be deemed to have been converted into the right to
receive and become exchangeable for, at the Effective Time, the Merger
Consideration in the manner provided in Section 3.1.1 hereof.

         3.3.2 Cargill shall give Westbank (i) prompt notice of any demands for
appraisal filed pursuant to Title 8 of Section 262 of Delaware General
Corporation Law, received by it, withdrawals of such demands, and any other
instruments served in connection with such demands pursuant to the Delaware
General Corporation Law and received by it and (ii) the opportunity to direct
all negotiations and proceedings with respect to demands under Delaware General
Corporation Law consistent with the obligations thereunder. Neither party shall,
except with the prior written consent of the other party, (x) make any payment
with respect to any such demand, (y) offer to settle or settle any such demand
or (z) waive any failure to timely deliver a written demand in accordance with
the Delaware General Corporation Law.

         3.4 SURRENDER OF SHARES; STOCK TRANSFER BOOKS.

         3.4.1 Prior to the Effective Time, Westbank shall designate an exchange
agent (the "Exchange Agent"), reasonably acceptable to Cargill, to act as agent
for the holders of Shares in connection with the Merger. After the Effective
Time, holders of certificates representing outstanding Shares, upon surrender of
such certificates to the Exchange Agent, shall be entitled to receive the shares
of Westbank and or funds to which holders of Shares shall become entitled
pursuant to Section 3.1. Immediately prior to the Effective Time, Westbank shall
deposit, or cause to be deposited, with the Exchange Agent, for the benefit of
the holders of certificates evidencing such Shares (the "Certificates"), for
exchange in accordance with this Article III, such amount of shares of Westbank
Common Stock and cash as is sufficient to pay the aggregate Merger Consideration
which holders of Shares are entitled to receive in exchange for outstanding
Shares.

         3.4.2 Promptly after the Effective Time (but in no event more than
three business days thereafter), Westbank shall cause to be mailed to each
person who was, at the Effective Time, a holder of record of Shares entitled to
receive the Merger Consideration a form of letter of transmittal (which shall
specify that delivery shall be effected, and risk of loss and title to the
Shares shall pass, only upon proper delivery of the Shares to the Exchange
Agent) and instructions for use in effecting the surrender of the Shares
pursuant to such letter of transmittal. Cargill shall have the right to review
the letter of transmittal, the instructions and any accompanying letter. Upon
surrender to the Exchange Agent of a Share, together with such letter of
transmittal, duly completed and validly executed in accordance with the
instructions thereto, and such other documents as may be required pursuant to
such instructions, the holder of such Share shall be entitled to receive in
exchange therefor the Merger Consideration for each Share formerly evidenced by
such Share, and such Share shall then be canceled. No interest shall accrue or
be paid for the period following the Effective Time on the Merger Consideration
payable upon the surrender of any

                                       -9-

   162



Share for the benefit of the holder of such Share. Until surrendered as provided
in this Section 3.4.2, each outstanding share which, before the Effective Date,
represented Shares will be deemed for all corporate purposes to represent the
number of whole shares of Westbank Common Stock into which the Shares were
converted and the right to receive cash in lieu of fractional shares. However,
until such outstanding shares formerly representing Cargill Shares are so
surrendered, no dividend or distribution payable to such holders of record of
Westbank Common Stock shall be paid to any such holder of such outstanding
shares, but upon surrender of such outstanding shares by such holder there shall
be paid to such holder the amount of any dividends or distribution, without
interest, theretofore paid with respect to such whole shares of Westbank Common
Stock, but not paid to such holder, and which dividends or distribution had a
record date occurring on or after the Effective Date and the amount of any cash,
without interest, payable to such holder in lieu of fractional shares pursuant
to Section 3.1 hereof. If payment of the Merger Consideration is to be made to a
person other than the person in whose name the surrendered Share is registered
on the stock transfer books of Cargill, it shall be a condition of payment that
the Share so surrendered shall be endorsed properly or otherwise be in proper
form for transfer and that the person requesting such payment shall have paid
all transfer and other taxes required by reason of the payment of the Merger
Consideration to a person other than the registered holder of the Share
surrendered or shall have established to the satisfaction of the Surviving
Corporation that such taxes either have been paid or are not applicable.

         3.4.3 At any time following the twelfth month after the Effective Time,
Westbank shall be entitled to require the Exchange Agent to deliver to it any
stock certificates representing shares of Westbank Common Stock or funds which
had been made available to the Exchange Agent and not disbursed to holders of
Shares (including, without limitation, all interest and other income received by
the Exchange Agent in respect of all funds made available to it), and thereafter
such holders shall be entitled to look to Westbank (subject to abandoned
property, escheat and other similar laws) with respect to any Merger
Consideration that may be payable upon due surrender of the Shares held by them.
Notwithstanding the foregoing, neither Westbank nor Park West Bank nor the
Exchange Agent shall be liable to any holder of a Share for any Merger
Consideration delivered in respect of such Share to a public official pursuant
to any abandoned property, escheat or other similar law.

         3.4.4 At the close of business on the Effective Date, the stock
transfer books of Cargill shall be closed and thereafter there shall be no
further registration of transfers of Shares on the records of Cargill. From and
after the Effective Time, the holders of Shares outstanding immediately prior to
the Effective Time shall cease to have any rights with respect to such Shares
except as otherwise provided herein or by applicable law.

         3.4.5 In the event any Share shall have been lost, stolen or destroyed,
upon the making of an affidavit of that fact by the person claiming such Share
to be lost, stolen or destroyed and, if required by Westbank, upon the posting
by such person of a bond in such amount as Westbank or Park West Bank may
reasonably direct as indemnity against any claim that may be made against it
with respect to such Certificate, the Exchange Agent will issue in exchange for
such lost, stolen or destroyed Certificate, the cash representing the Merger
Consideration deliverable in respect thereof pursuant to this Agreement.

         3.5   RESERVATION OF SHARES OF WESTBANK COMMON STOCK.  Westbank has
available and shall reserve for issuance a sufficient number of authorized but
unissued shares of its common stock for the purpose of issuing shares of
Westbank Common Stock to the Cargill shareholders in accordance with this
Article III.

all of its properties and assets and to carry on its business as now conducted
and is duly licensed or qualified to do business and is in good standing in each
jurisdiction in which its ownership or leasing of property or the conduct of its

holding company with the OTS. Cargill has heretofore delivered to Westbank true
and complete copies of the Certificate of Incorporation and Bylaws of Cargill as

jurisdiction in which its ownership or leasing of property or the conduct of its
business requires such qualification, except where the failure to be so
licensed, qualified or in good standing would not have a Material Adverse Effect
on Cargill. The deposit accounts of Cargill Bank are insured by the SAIF, to the
maximum extent permitted by the FDIA.

         Cargill Bank has paid all deposit insurance premiums and assessments
required by the FDIC including the payment in full of all special assessments to

into this Agreement, including the Stock Option Agreement attached as Exhibit C
hereto, and (subject to receipt of all necessary approvals of Governmental

Agreement and the consummation of the transactions contemplated hereby have been
duly and validly authorized by all necessary corporate action in respect thereof
on the part of Cargill, except for the approval of this Agreement by Cargill's
shareholders. This Agreement has been duly and validly executed and delivered by
Cargill and constitutes the legal, valid and binding obligations of Cargill,
enforceable against Cargill in accordance with its terms, subject, as to
enforceability, to bankruptcy, insolvency and other laws of general
applicability relating to or affecting creditors' rights and to general equity
principles.

         4.5.2 Except as Previously Disclosed, neither the execution and
delivery of this Agreement, nor consummation of the transactions contemplated
hereby, nor compliance by Cargill with any of the provisions hereof (i) does or
will conflict with or result in a breach of any provisions of the Articles of
Incorporation or Bylaws of Cargill or the equivalent documents of any Cargill
Subsidiary, (ii) violate, conflict with or result in a breach of any term,
condition or provision of, or constitute a default (or an event which, with
notice or lapse of time, or both, would constitute a default) under, or give
rise to any right of termination, cancellation or acceleration with respect to,
or result in the creation of any lien, charge or encumbrance upon any property
or asset of Cargill or any Cargill Subsidiary pursuant to, any material note,
bond, mortgage, indenture, deed of trust, license, lease, agreement or other
instrument or obligation to which Cargill or any Cargill Subsidiary is a party,
or by which any of their respective properties or assets may be bound or
affected, or (iii) subject to receipt of all required governmental and

   165




         4.5.4 As of the date hereof, neither Cargill nor Cargill Bank is aware
of any reasons relating to Cargill or Cargill Bank (including without limitation
Community Reinvestment Act compliance) (a) why all consents and approvals shall
not be procured from all regulatory agencies having jurisdiction over the
transactions contemplated by this Agreement as shall be necessary for (i)
consummation of the transactions contemplated by this Agreement, (ii) the
continuation by Westbank after the Effective Time of the business of each of
Westbank and Cargill as such business is carried on immediately prior to the
Effective Time, free of any conditions or requirements which, in the reasonable
opinion of Cargill, could have a Material Adverse Effect on Westbank or Cargill
or materially impair the value of Cargill and Cargill Bank to Westbank, or (b)
except as Previously Disclosed, which may prevent the transaction contemplated
hereby, including the Merger, from qualifying for pooling of interests
accounting treatment or as a reorganization within the meaning of Section 368(a)
of the Code.

all securities documents required by the Securities Laws and such documents
complied in all material respects with the Securities Laws and did not contain
any untrue statement of a material fact or omit to state any material fact

   166

         4.9.1 To the best of Cargill's knowledge, Cargill and its Subsidiaries
are in material compliance with all Environmental Laws. Neither Cargill nor any
Cargill Subsidiary has received any communication alleging that Cargill or any
Cargill Subsidiary is not in such compliance and, to the best knowledge of
Cargill, there are no present circumstances that would prevent or interfere with
the continuation of such compliance.

         4.9.2 To the best of Cargill's knowledge, none of the properties
presently or formerly owned, leased or operated by Cargill or a Cargill
Subsidiary, or in which Cargill or any Cargill Subsidiary has a lien or other
security interest, has been or is in material violation of or materially liable
under any Environmental Law.

         4.9.3 To the best of Cargill's knowledge, there are no past or present
actions, activities, circumstances, conditions, events or incidents that could
reasonably form the basis of any material Environmental Claim or other claim or
action or governmental investigation that could result in the imposition of any
material liability arising under any Environmental Law against Cargill or a
Cargill Subsidiary or against any person or entity whose liability for any
Environmental Claim Cargill or a Cargill Subsidiary has or may have retained or
assumed either contractually or by operation of law.

         4.9.4 Neither Cargill nor any Cargill Subsidiary have conducted any
environmental studies during the past five years with respect to any properties
owned by Cargill or a Cargill Subsidiary.

         4.10 TAX MATTERS

         4.10.1 Cargill and its Subsidiaries have timely filed all federal,
state and local (and, if applicable, foreign) income, franchise, bank, excise,
real property, personal property and other tax returns required by applicable
law to be filed by them (including, without limitation, estimated tax returns,
income tax returns, information returns and withholding and employment tax

change of accounting method) or (iii) has filed a consent pursuant to Section

cancellation of any of the same is threatened.

         4.12.2 Neither Cargill nor a Cargill Subsidiary is in violation of its

zoning, anti-discrimination, antitrust, and wage and hour laws, ordinances,
orders, rules and regulations), or in default with respect to any order, writ,

that Cargill or a Cargill Subsidiary is in violation of any of the foregoing
which could reasonably be expected to have a Material Adverse Effect on Cargill.

of understanding or written commitment (other than those of general
applicability to all banks and holding companies thereof), and neither of them
has received any written communication requesting that it enter into any of the
foregoing, except as disclosed in Schedule 4.12.2, which consists of Board
Resolutions, no regulatory agency has initiated any formal or informal
proceeding or, taken any formal or informal supervisory action to the best
knowledge of Cargill, investigation into the business or operations of Cargill
or any of the Cargill Subsidiaries since prior to September 30, 1992. Cargill

         4.14.1 Cargill has Previously Disclosed all stock option, employee
stock purchase and stock bonus plans, qualified pension or profit-sharing plans,
any deferred compensation, consultant, bonus or group insurance contract or any
other incentive, health and welfare or employee benefit plan or agreement
maintained for the benefit of employees or former employees of Cargill or any
Cargill Subsidiary (the "Cargill Employee Plans"), whether written or oral, and
Cargill has previously furnished or made available to Westbank accurate and
complete copies of the same together with (i) the most recent actuarial and
financial reports prepared with respect to any qualified plans, (ii) the most
recent annual reports filed with any governmental agency, and (iii) all rulings
and determination letters and any open requests for rulings or letters that
pertain to any qualified plan.

         4.14.2 None of Cargill, any Cargill Subsidiary, any pension plan
maintained by either of them and qualified under Section 401 of the Code or, to
the best of Cargill's knowledge, any fiduciary of such plan has incurred any
material liability to the PBGC or the Internal Revenue Service with respect to
such plan. To the best of Cargill's knowledge, no reportable event under Section
4043(b) of ERISA has occurred with respect to any such pension plan.

         4.14.3 Neither Cargill nor any Cargill Subsidiary participates in or
has incurred any liability under Section 4201 of ERISA for a complete or partial
withdrawal from a multi-employer plan (as such term is defined in ERISA).

         4.14.4 A favorable determination letter has been applied for from the
Internal Revenue Service with respect to the Financial Institutions Retirement
Fund as adopted by Cargill Bank, which is an "employee pension benefit plan" (as
defined in Section 3(2) of ERISA) (a "Cargill Pension Plan") which is intended
to qualify under Section 401 of the Code to the effect that such plan is
qualified under Section 401 of the Code and the trust associated with such
employee pension plan is tax exempt under Section 501 of the Code. No such
letter has yet been issued by the IRS, but there has been no indication from the
IRS that a favorable determination letter will be withheld or that Cargill
Bank's request will be denied.

have been operated in compliance in all material respects with the applicable
provisions of ERISA, the Code, all regulations, rulings and announcements
promulgated or issued thereunder and all other applicable governmental laws and

against any of the Cargill Employee Plans or any trust related thereto or any
fiduciary thereof.

of any reasons relating to Westbank or Park West Bank or any of its Subsidiaries
(including without limitation Community Reinvestment Act compliance) (a) why all
consents and approvals shall not be procured from all regulatory agencies having
jurisdiction over the transactions contemplated by this Agreement as shall be
necessary for (i) consummation of the transactions contemplated by this
Agreement and (ii) the continuation by Westbank and Park West Bank after the
Effective Time of the business of each of Westbank, Park West Bank or Cargill as
such business is carried on immediately prior to the Effective Time, free of any
conditions or requirements which, in the reasonable opinion of Westbank or Park
West Bank, could have a Material Adverse Effect on Westbank, Park West Bank,
Cargill or Cargill Bank or materially impair the value of Cargill and Cargill
Bank to Westbank or (b) which may prevent the transactions contemplated hereby,
including the Merger, from qualifying for pooling of interests accounting
treatment or as a reorganization within the meaning of Section 368(a) of the
Code.

         5.6 REGULATORY REPORTS

         5.6.1 Since January 1, 1993, Westbank has timely filed (as applicable)
all Securities Documents required by the Securities Laws and such Securities
Documents complied in all material respects with the Securities Laws and did not

Westbank believes has not been corrected or changed as required as of the date
hereof in all material respects.

Subsidiary (the "Westbank Employee Plans"), whether written or oral.

         5.14.2 None of Westbank, any Westbank Subsidiary, any pension plan
maintained by any of them and qualified under Section 401 of the Code or, to the
best of Westbank's knowledge, any fiduciary of such plan has incurred any

withdrawal from a multi-employer plan (as such term is defined in ERISA).

         5.14.4 A favorable determination letter has been issued by the Internal
Revenue Service with respect to each Westbank Employee Plan which is an
"employee pension benefit plan" (as defined in Section 3(2) of ERISA) (a
"Westbank Pension Plan") which is intended to qualify under Section 401 of the
Code to the effect that such plan is qualified under Section 401 of the Code and
the trust associated with such employee pension plan is tax exempt under Section
501 of the Code. No such letter has been revoked or, to the best of Westbank's
knowledge, is threatened to be revoked and Westbank does not know of any ground
on which such revocation may be based. Neither Westbank nor any Westbank
Subsidiary has any liability under any such plan that is not reflected on the
consolidated statement of financial condition of Westbank at December 31, 1997
included in the Westbank Financial Statements,

                                      -25-

(which shall mean any transaction prohibited by Section 406 of ERISA and not
exempt under Section 408 of ERISA or Section 4975 of the Code) has occurred with
respect to any Westbank Employee Plan which would result in the imposition,
directly or indirectly, of a material excise tax under Section 4975 of the Code
or otherwise have a Material Adverse Effect on Westbank.

         5.14.6 Full payment has been made (or proper accruals have been

date hereof, and full payment will be so made (or proper accruals will be so
established) of all contributions which are required for periods after the date
hereof and prior to the Effective Time, under the terms of each Westbank
Employee Plan or ERISA; to the best of Westbank's knowledge, no accumulated
funding deficiency (as defined in Section 302 of ERISA or Section 412 of the
Code), whether or not waived, exists with respect to any Westbank Pension Plan,
and there is no "unfunded current liability" (as defined in Section 412 of the
Code) with respect to any Westbank Pension Plan.

have been operated in compliance in all material respects with the applicable
provisions of ERISA, the Code, all regulations, rulings and announcements
promulgated or issued thereunder and all other applicable governmental laws and
regulations.

threatened claims (other than routine claims for benefits) by, on behalf of or
against any of the Westbank Employee Plans or any trust related thereto or any
fiduciary thereof.

commitment, arrangement, lease, insurance policy or other instrument to which it
is a party or by which its assets, business or operations may be bound or
affected, whether entered into in the ordinary course of business or otherwise
and whether written or oral, and there has not occurred any event that with the
lapse of time or the giving of notice, or both, would constitute such a default
or non-compliance.

Westbank nor any Westbank Subsidiary, nor any of their respective directors,
officers or employees, has employed any broker or finder or incurred any
liability for any broker or finder fees or commissions in connection with the
transactions contemplated hereby.

reasonable amounts with financially sound and reputable insurance companies
against such risks as companies engaged in a similar business would, in
accordance with good business practice, customarily be insured and has
maintained all insurance required by applicable laws and regulations.

         5.18 LOAN PORTFOLIO. Westbank has Previously Disclosed all of the loans
in original principal amount in excess of $100,000 of Westbank or any Westbank

which are valid and enforceable in accordance with their respective terms and no
such real property lease will terminate or lapse prior to the Effective Time.

         5.20 LABOR. No work stoppage involving Westbank or any Westbank
Subsidiary is pending or, to the best knowledge of Westbank, threatened. Neither
Westbank nor any Westbank Subsidiary is involved in, or threatened with or
affected by, any labor dispute, arbitration, lawsuit or administrative
proceeding involving its employees which could have a Material Adverse Effect on
Westbank. Employees of Westbank and the Westbank Subsidiaries are not
represented by any labor union nor are any collective bargaining agreements

nondeductible pursuant to Section 162(m) of the Code;

                  (p) take any action that would result in the representations
and warranties of Cargill contained in this Agreement not being true and correct
on the date of this Agreement or at any future date on or prior to the Effective
Date;

                  (q) incur in connection with this Agreement and the
transactions contemplated herein, expenses including, but not limited to,
advisory, investment banking, legal, accounting, tax advisory, or similar fees

                  (r) agree to do any of the foregoing.

         6.2 CURRENT INFORMATION. During the period from the date of this
Agreement to the Effective Time, Cargill will cause one or more of its
representatives to confer with representatives of Westbank and report the
general status of its ongoing operations at such times as Westbank may
reasonably request. Cargill will promptly notify Westbank of any material change
in the normal course of its business or in the operation of its properties and,
to the extent permitted by applicable law, of any governmental complaints,
investigations or hearings (or communications indicating that the same may be
contemplated), or the institution or the threat of material litigation involving
Cargill. Cargill will also provide Westbank such information with respect to
such events as Westbank may reasonably request from time to time. As soon as
reasonably available, but in no event more than 45 days after the end of each
calendar quarter ending after the date of this Agreement (other than the last
quarter of each fiscal year ending December 31), Cargill will deliver to
Westbank its quarterly report, and, as soon as reasonably available, but in no
event more than 90 days after the end of each fiscal year, Cargill will deliver
to Westbank its Annual Report. Within 25 days after the end of each month,
Cargill will deliver to Westbank a consolidated balance sheet and a consolidated
statement of operations, without related notes, for such month.

         6.3 ACCESS TO PROPERTIES AND RECORDS. Cargill shall permit Westbank
reasonable access upon reasonable notice to its properties and those of the

including, but not limited to, all books of account (including the general
ledger), tax records, minute books of directors' and stockholders' meetings,
organizational documents, by-laws, material contracts and agreements, filings
with any regulatory authority, litigation files, plans affecting employees, and
any other business activities or prospects in which Westbank may have a
reasonable interest; provided, however, that Cargill shall not be required to
take any action that would provide access to or to disclose information where
such access or disclosure would violate or prejudice the rights or business
interests or confidences of any customer or other person or would result in the
waiver by it of the privilege protecting communications between it and any of
its counsel. Cargill shall provide and shall request its auditors to provide
Westbank with such historical financial information regarding it (and related
audit reports and consents) as Westbank may reasonably request for securities
disclosure purposes.

Cargill Subsidiaries made by such accountants.

         6.4.2 As soon as practicable, Cargill will furnish to Westbank copies

with respect to the condition or activities of Cargill or any of the Cargill
Subsidiaries.

         6.4.4 With reasonable promptness, Cargill will furnish to Westbank such
additional financial data as Westbank may reasonably request, including without
limitation, detailed monthly financial statements and loan reports.

         6.5 DISCLOSURE SUPPLEMENTS. From time to time prior to the Effective
Time, Cargill will promptly supplement or amend the Disclosure Schedules
delivered in connection herewith pursuant to Article IV with respect to any
material matter hereafter arising which, if existing, occurring or known at the
date of this Agreement, would have been required to be set forth or described in
such Disclosure Schedule or which is necessary to correct any information in
such Schedules which has been rendered inaccurate thereby. No supplement or
amendment to such Schedules shall have any effect for the purpose of determining
satisfaction of the conditions set forth in Article IX.

         6.6 CONSENTS AND APPROVALS OF THIRD PARTIES. Cargill shall use all
reasonable efforts to obtain as soon as practicable all consents and approvals
of any other Persons necessary or desirable for the consummation of the
transactions contemplated by this Agreement. Without limiting the generality of
the foregoing, Cargill may, with the prior consent of Westbank, which shall not
be unreasonably withheld utilize the services of a professional proxy soliciting
firm to help obtain the shareholder vote required to be obtained by it
hereunder.

         6.7 ALL REASONABLE EFFORTS. Subject to the terms and conditions herein
provided, Cargill agrees to use all reasonable efforts to take, or cause to be
taken, all corporate or other action and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement.

         6.8 FAILURE TO FULFILL CONDITIONS. In the event that Cargill determines
that a condition to its obligation to complete the Merger cannot be fulfilled
and that it will not waive that condition, it will promptly notify Westbank.

         6.9 NO SOLICITATION. Unless and until this Agreement shall have been
properly terminated by either party pursuant to Section 11.1 hereof, neither
Cargill nor any of its subsidiaries shall (and Cargill and Cargill Bank shall
use all commercially reasonable efforts to cause its representatives, including,
but not limited to, investment bankers, attorneys and accountants, not to),
directly or indirectly, encourage, solicit, initiate or participate in any
discussions or negotiations with, or, provide any information to, any
corporation, partnership, person or other entity or group (other than Westbank
and

                                      -31-

   184



its affiliates or Representatives) concerning any merger, tender offer, sale of
substantial assets, sale of shares of capital stock or debt securities or
similar transaction involving Cargill or Cargill Bank (an "Acquisition
Transaction"); provided, however that Cargill and its representatives shall be
permitted to participate in discussions or negotiations with, or provide
information to, any other corporation, partnership, person or other entity or
group with respect to an Acquisition Transaction if the Board of Directors of
Cargill determines (in good faith upon the advice of outside counsel) that their
fiduciary duties require them to do so. Notwithstanding the foregoing, nothing
contained in this Section 6.9 shall prohibit Cargill or its Board of Directors
from taking and disclosing to Cargill's stockholders a position with respect to
a tender offer by a third party pursuant to Rules 14d-9 and 14e-2(a) promulgated
under the Exchange Act or from making such disclosure to Cargill's stockholders
which, in the judgment of the Board of Directors (upon the advice of counsel),
may be required under applicable law or is necessary in order to comply with its
fiduciary obligations. Cargill will immediately communicate to Westbank the
terms of any proposal, discussion, negotiation or inquiry relating to an
Acquisition Transaction and the identity of the party making such proposal or
inquiry which it may receive in respect of any such transaction (which shall
mean that any such communication shall be delivered no less promptly than by
telephone within 24 hours of Cargill's receipt of any such proposal or inquiry)
or its receipt of any request for information from the FRB, the DOJ, or any
other governmental agency or authority with respect to a proposed Acquisition
Transaction. Cargill shall continue to consult with Westbank after receipt of
such proposal or commencement of such discussion or negotiation relating to an
Acquisition Transaction, and will not take any action with respect to such
proposed Acquisition Transaction except after reasonable consultation with
Westbank.

         6.10 RESTRICTIONS ON SALE OF CARGILL COMMON STOCK. Cargill shall cause
each director, executive officer and other person who is an "affiliate" (for
purposes of Rule 145 under the Securities Act and for purposes of qualifying the
Merger for "pooling of interests" accounting treatment) of such party to deliver
to Westbank, effective on the date of this Agreement, written agreements in the
form attached hereto as Exhibit A, providing that such person will not sell,
pledge, transfer or otherwise dispose of any shares of Cargill Common Stock,
held by such "affiliate" and, in the case of the "affiliates" of Cargill, the
shares of Westbank Common Stock to be received by such "affiliate" in the
Merger: (1) otherwise than in compliance with the applicable provisions of the
Securities Act and the rules and regulations thereunder; and (2) unless the
Merger does not qualify for "pooling of interests" accounting treatment, during
the period commencing 30 days prior to consummation of the Merger and ending at
the time of the publication of financial results covering at least thirty days
of combined operations of Cargill and Westbank.

                                   ARTICLE VII
                              COVENANTS OF WESTBANK

         7.1 CONDUCT OF BUSINESS. During the period from the date of this
Agreement to the Effective Time, except with the written consent of Cargill and
except as provided below, Westbank will take no action which would (i)
materially adversely affect the ability of Westbank or Cargill to obtain any
necessary approvals of governmental authorities required for the transactions
contemplated hereby or materially increase the period of time necessary to
obtain such approvals, or (ii) materially adversely affect its ability to
perform its covenants and agreements under this Agreement, or (iii) result in
the representations and warranties of Westbank contained in this Agreement not
being true and correct on the date of this Agreement or at any future date on or
prior to the Closing Date; provided that nothing herein contained shall preclude
Westbank from taking any action Previously Disclosed. Westbank will cooperate
and take all reasonable actions within its control to cause the Merger to
qualify for "pooling of interests" accounting treatment and as a reorganization
within the meaning of Section 368(a) of the Code.

Agreement to the Effective Time, Westbank will cause one or more of its
representatives to confer with representatives of Cargill and report the general
status of its ongoing operations at such times as Cargill may reasonably
request. Westbank will promptly notify Cargill of any material change in the
normal course of its business or in the operation of its properties and, to the
extent permitted by applicable law, of any governmental complaints,
investigations or hearings (or communications indicating that the same may be
contemplated), or the institution or the threat of material litigation involving
Westbank. Westbank will also provide Cargill such information with respect to
such events as Cargill may reasonably request from time to time. As soon as
reasonably available, but in no event more than 45 days after the end of each
calendar quarter ending after the date of this Agreement (other than the last
quarter of each fiscal year ending December 31), the Westbank will deliver to
Cargill a consolidated balance sheet and a consolidated statement of operations,
without related notes, for such quarter prepared in accordance with generally
accepted accounting principles, and within 25 days after the end of each month,

but not limited to, all books of account (including the general ledger), tax
records, minute books of directors' and stockholders' meetings, organizational
documents, by-laws, material contracts and agreements, filings with any
regulatory authority, litigation files, plans affecting employees, and any other
business activities or prospects in which Cargill may have a reasonable
interest; provided, however, that Westbank shall not be required to take any
action that would provide access to or to disclose information where such access
or disclosure would violate or prejudice the rights or business interests or
confidences of any customer or other person or would result in the waiver by it
of the privilege protecting communications between it and any of its counsel.

         7.4 FINANCIAL AND OTHER STATEMENTS.

         7.4.1 Promptly upon receipt thereof, Westbank will furnish to Cargill
copies of each annual, interim or special audit of the books of Westbank and its
subsidiaries made by its independent accountants and copies of all internal
control reports submitted to Westbank by such accountants in connection with
each annual, interim or special audit of the books of Westbank and its
subsidiaries made by such accountants.

         7.4.2 As soon as practicable, Westbank will furnish to Cargill copies
of all such financial statements and reports as it or any Subsidiary shall send

Commissioner, the OTS or any other regulatory authority, except as legally
prohibited thereby.

         7.5 DISCLOSURE SUPPLEMENTS. From time to time prior to the Effective
Time, Westbank will promptly supplement or amend the Disclosure Schedules
delivered in connection herewith pursuant to Article V with respect to any
material matter hereafter arising which, if existing, occurring or known at the
date of this Agreement, would have been required to be set forth or described in
such Disclosure Schedules or which is necessary to correct any information in
such Schedules which has been rendered inaccurate thereby. No supplement or
amendment to such Schedules shall have any effect for the purpose of determining
satisfaction of the conditions set forth in Article IX.

         7.6 CONSENTS AND APPROVALS OF THIRD PARTIES. Westbank shall use all
reasonable efforts to obtain as soon as practicable all consents and approvals
of any other Persons necessary or desirable for the consummation of the
transactions contemplated by this Agreement.

         7.7 ALL REASONABLE EFFORTS. Subject to the terms and conditions herein
provided, Westbank agrees to use all reasonable efforts to take, or cause to be
taken, all action and to do, or cause to be done, all things necessary, proper
or advisable under applicable laws and regulations to consummate and make
effective the transactions contemplated by this Agreement.

         7.8 FAILURE TO FULFILL CONDITIONS. In the event that Westbank
determines that a condition to its obligation to complete the Merger cannot be
fulfilled and that it will not waive that condition, it will promptly notify
Cargill.

         7.9 EMPLOYEE BENEFITS

         7.9.1 While it is the intention of Westbank to offer employment to each
of the current employees of Cargill and its Subsidiaries, nothing in this
Agreement shall give any employee of Cargill or its Subsidiaries a right to
continuing employment with Westbank or any Subsidiary thereof after the
Effective Time.

         7.9.2 As soon as practicable after the Effective Time, Westbank shall
provide or cause to be provided to all employees of Cargill and any Cargill
Subsidiary who remain employed by Westbank or any Westbank Subsidiary after the
Effective Time with employee benefits which, in the aggregate, are no less
favorable than those generally afforded in the banking industry to other
employees, holding similar positions.

         7.9.3 Cargill has Previously Disclosed to Westbank certain employment
and change of control agreements, and deferred compensation plans as
Supplemental Retirement Plans (collectively, "Benefit Agreements") and the
Cargill Employee Stock Ownership Plan ("ESOP") which was terminated in 1995.
Following the Effective Time, Westbank shall honor or cause its Subsidiaries to
honor in accordance with their terms all such Previously Disclosed Benefit
Agreements and assume or cause its Subsidiaries to assume all duties,
liabilities and obligations under such agreements and arrangements. Westbank
agrees that (i) the consummation of the transactions contemplated hereby
constitutes a "Change in Control" as defined in the Benefit Agreements, and (ii)
Cargill's President who is the only employee who is a party to an employment
agreement with Cargill will be deemed to have suffered a material change in his
responsibilities and supervision as of the Effective Time, it being understood
that Westbank shall assume the employment agreement with the President of
Cargill and agrees to extend the term of such agreement until March 31, 2000.
Notwithstanding anything to the contrary contained in this Agreement, in no
event shall any party to this Agreement take any action or make any payments
that would result, either individually or in the aggregate, in the payment of an
"excess parachute payment" within the meaning of Section 280G of the Code or
that would result, either individually or in the aggregate, in payments that
would be nondeductible pursuant to Section 162(m) of the Code.

         7.10 DIRECTORS AND OFFICERS INDEMNIFICATION AND INSURANCE.

         7.10.1 With regard to the Cargill Directors who continue to serve on
the Cargill Bank Board of Directors as well as those directors who elect to
terminate their service as directors, Westbank shall maintain, in effect for
three years from the Effective Time, the current directors' and officers'
liability insurance policies maintained by Cargill (provided, that Westbank may
substitute therefor policies of at least the same coverage containing terms and
conditions which are not materially less favorable) with respect to matters
occurring prior to the Effective Time; provided, however, that in no event shall
Westbank be required to expend pursuant to this Section 7.10.1 more than $30,000
in the aggregate. In connection with the foregoing, Cargill agrees to provide
such insurer or substitute insurer with such representations as such insurer may
request with respect to the reporting of any prior claims.

         7.10.2 From and after the Effective Time, Westbank shall indemnify,
defend and hold harmless each person who is now, or who has been at any time
before the date hereof or who becomes before the Effective Time, an officer or
director of Cargill or the Cargill Subsidiaries or any of their respective
subsidiaries (the "Indemnified Parties") against all losses, claims, damages,
costs, expenses (including attorney's fees), liabilities or judgments or amounts
that are paid in settlement (which settlement shall require the prior written
consent of Westbank, which consent shall not be unreasonably withheld) of or in
connection with any claim, action, suit, proceeding or investigation, whether
civil, criminal, or administrative (each a "Claim"), in which an Indemnified
Party is, or is threatened to be made, a party or witness in whole or in part on
or arising in whole or in part out of the fact that such person is or was a
director, officer or employee of Cargill or any of its subsidiaries if such
Claim pertains to any matter of fact arising, existing or occurring before the
Effective Time (including, without limitation, the Merger and the other
transactions contemplated hereby), regardless of whether such Claim is asserted
or claimed before, or at or after, the Effective Time (the "Indemnified
Liabilities"), to the fullest extent permitted under applicable state or federal
law in effect as of the date hereof or as amended applicable to a time before
the Effective Time and under Cargill's and Cargill Bank's Articles of
Organization or Charter and By-Laws. Westbank shall pay expenses in advance of
the final disposition of any such action or proceeding to each Indemnified Party
to the full extent permitted by applicable state or federal law in effect as of
the date hereof or as amended applicable to a time before the Effective Time
upon receipt of an undertaking to repay such advance payments if he shall be
adjudicated or determined to be not entitled to indemnification in the manner
set forth below.

         Any Indemnified Party wishing to claim indemnification under this
Section 7.10.2 upon learning of any Claim, shall notify Westbank (but the
failure so to notify Westbank shall not relieve it from any liability which it
may have under this Section 7.10.2, except to the extent such failure materially
prejudices Westbank) and shall deliver to Westbank the undertaking referred to
in the previous sentence. In the event of any such Claim (whether arising before
or after the Effective Time) (1) Westbank shall have the right to assume the
defense thereof (in which event the Indemnified Parties will cooperate in the
defense of any such matter) and upon such assumption Westbank shall not be
liable to any Indemnified Party for any legal expenses of other counsel or any
other expenses subsequently incurred by any Indemnified Party in connection with
the defense thereof, except that if Westbank elects not to assume such defense,
or counsel for the Indemnified Parties reasonably advises the Indemnified
Parties that there are or may be (whether or not any have yet actually arisen)
issues which raise conflicts of interest between Westbank and the Indemnified
Parties, the Indemnified Parties may retain counsel reasonably satisfactory to
them, and Westbank shall pay the reasonable fees and expenses of such counsel
for the Indemnified Parties, (2) Westbank shall be obligated pursuant to this
paragraph to pay for only one firm of counsel for all Indemnified Parties whose
reasonable fees and expenses shall be paid promptly as statements are received,
(3) Westbank shall not be liable for any settlement effected without its prior
written consent (which consent shall not be unreasonably withheld) and (4) no
Indemnified Party shall be entitled to indemnification hereunder with respect to
a matter as to which (x) he shall have been adjudicated in any

                                      -35-

   188



proceeding not to have acted in good faith in the reasonable belief that his
action was in the best interests of Cargill or any Subsidiary, or (y) in the
event that a proceeding is compromised or settled so as to impose any liability
or obligation upon an Indemnified Party, if there is a determination that with
respect to said matter said Indemnified Party did not act in good faith in the
reasonable belief that his action was in the best interests of Cargill or any
Subsidiary. The determination shall be made by directors of Westbank who were
formerly directors of Cargill and who are not involved in such proceeding a
committee of three disinterested former Cargill Directors chosen by all of the
disinterested former Cargill Directors for the purpose of making such
determination or by independent legal counsel acceptable to both Westbank and a
majority of the disinterested former Cargill Directors.

         7.10.3 In the event that either Westbank or any of its successors or
assigns (i) consolidates with or merges into any other entity and shall not be
the continuing or surviving bank or entity of such consolidation or merger or
(ii) transfers all or substantially all of its properties and assets to any
person, then, and in each such case, proper provision shall be made so that the
successors and assigns of Westbank shall assume the obligations set forth in
this Section 7.10.

         7.10.4 The obligations of Westbank provided under this Section 7.10 are
intended to be enforceable against Westbank directly by the Indemnified Parties
and shall be binding on all respective successors and permitted assigns of
Westbank.

         7.11 RESTRICTIONS ON SALE OF WESTBANK COMMON STOCK. Westbank shall
cause each director, executive officer and other person who is an
"affiliate"(for purposes of qualifying the Merger for "pooling of interests"
accounting treatment) of such party to deliver, as soon as practicable after the
date of this Agreement, and prior to the date of the Cargill Shareholders
Meeting, written agreements in the form attached hereto as Exhibit D, providing
that such person will not sell, pledge, transfer or otherwise dispose of any
shares of Westbank Common Stock, held by such "affiliate" and, in the case of
the "affiliates" of Westbank, the shares of Westbank Common Stock to be received
by such "affiliate" in the Merger; unless the Merger does not qualify for
"pooling of interests" accounting treatment, during the period commencing 30
days prior to consummation of the Merger and ending at the time of the
publication of financial results covering at least thirty days of combined
operations of Westbank and Cargill.

         7.12 STOCK LISTING. Westbank Common Stock is listed on the Nasdaq
National Market System under the symbol "WBKC." Westbank agrees to use all
reasonable efforts to continue to qualify for listing on the Nasdaq National
Market System (or such other national securities exchange on which the shares of
Westbank Common Stock shall be listed as of the Effective Time), subject to
official notice of issuance, the shares of Westbank Common Stock to be issued in
the Merger.

         7.13 PUBLICATION OF COMBINED FINANCIAL RESULTS. Westbank, as the
Surviving Corporation shall publish no later than 30 days after the end of the
first month which includes at least 30 days of post-Merger combined operations,
combined sales and net income figures and any other financial information
necessary as contemplated by and in accordance with the terms of SEC Accounting
Series Release No. 135 and any related accounting rules.

concerning themselves and their Subsidiaries as is necessary in order to cause
the Prospectus and Proxy Statement, insofar as it relates to such corporations,

Westbank or Park West Bank and their Subsidiaries, to comply with Section 8.2.1.

         8.2.3 Cargill shall furnish Westbank or Park West Bank with such

         9.1 CONDITIONS TO EACH PARTY'S OBLIGATIONS UNDER THIS AGREEMENT. The
respective obligations of each party under this Agreement shall be subject to
the fulfillment at or prior to the Effective Time of the following conditions,
none of which may be waived:

         9.1.1 STOCKHOLDER APPROVAL. This Agreement and the transactions
contemplated hereby shall have been approved in accordance with applicable law,
Articles of Organization, By-laws and NASD policy by the requisite vote of the
stockholders of Cargill.

         9.1.2 INJUNCTIONS. None of the parties hereto shall be subject to any
order, decree or injunction of a court or agency of competent jurisdiction which
enjoins or prohibits the consummation of the transactions contemplated by this
Agreement.

         9.1.3 REGULATORY APPROVALS. All necessary approvals, authorizations and
consents of all governmental bodies required to consummate the transactions
contemplated by this Agreement shall have been obtained and shall remain in full
force and effect and all waiting periods relating to such approvals,
authorizations or consents shall have expired; and no such approval,
authorization or consent shall include any condition or requirement, not
reasonably foreseen as of the date of this Agreement or otherwise addressed on
or prior to the date hereof, that would, in the good faith reasonable judgment
of the Board of Directors of Westbank and Cargill, materially and adversely
affect the business, operations, financial condition, property or assets of the
combined enterprise or of Cargill or Cargill Bank or otherwise materially impair
the value of Cargill or Cargill Bank to Westbank.

         9.1.4 TAX OPINION. Receipt of an opinion of legal counsel, or other tax
advisor reasonably acceptable to the parties, or a private letter ruling from
the Internal Revenue Service, in the form and content reasonably satisfactory to
the parties hereto, and upon which Cargill shareholders may rely, subject to
standard representations and assumptions, to the effect that for federal income
tax purposes:

                           (i) The Merger will qualify as a "reorganization"
under Section 368(a) of the Code.

                           (ii) No gain or loss will be recognized by Westbank,
Park West Bank, Cargill or Cargill Bank by reason of the Merger.

   191



                           (iii) No gain or loss will be recognized by any
Cargill shareholder except those who elect to exercise dissenters' rights
(except in connection with the receipt of cash in lieu of a fractional share of
Westbank Common Stock) upon the exchange of Cargill Common Stock for Westbank
Common Stock in the Merger.

                           (iv) The basis of the Westbank Common Stock received
by a Cargill shareholder who exchanges Cargill Common Stock for Westbank Common
Stock will be the same as the basis of the Cargill Common Stock surrendered in
exchange therefor (subject to any adjustments required as the result of receipt
of cash in lieu of a fractional share of Westbank Common Stock).

                           (v) The holding period of the Westbank Common Stock
received by a Cargill shareholder receiving Westbank Common Stock will include
the period during which the Cargill Common Stock surrendered in exchange
therefore was held (provided that such Common Stock of such Cargill shareholder
was held as a capital asset at the Effective Time).

                           (vi) Cash received by a Cargill shareholder in lieu
of a fractional share interest of Westbank Common Stock will be treated as
having been received as a distribution in full payment in exchange for the
fractional share interest of Westbank Common Stock which he would otherwise be
entitled to receive and will qualify as capital gain or loss (assuming the
Cargill stock was a capital asset in his hands at the Effective Time).

         9.1.5 REGISTRATION STATEMENT. The Registration Statement shall have
been declared effective and shall not be subject to a stop order of the SEC and,
if the offer and sale of Westbank's Common Stock in the Merger pursuant to this

the Effective Time, whether before or after approval of the Merger by the
stockholders of Cargill:

         11.1.1 At any time by the mutual written agreement of Westbank and
Cargill;

         11.1.2 By either Cargill or Westbank (provided, that the terminating
party is not then in material breach of any representation, warranty, covenant
or other agreement contained herein) if there shall have been a material breach
of any of the representations or warranties set forth in this Agreement on the
part of the other party, which breach by its nature cannot be cured prior to the
Effective Time or within 30 business days after written notice by Westbank to
Cargill (or by Cargill to Westbank) of such breach (for purposes of this Section
11.1.2 a material breach shall be deemed to be a breach which has, either

party is not then in material breach of any representation, warranty, covenant
or other agreement contained herein) if there shall have been a material failure
to perform or comply with any of the covenants or agreements set forth in this

                                      -41-

   194



Agreement on the part of the other party, which failure shall not have been
cured within 30 business days after written notice by Westbank to Cargill (or by
Cargill to Westbank) of such failure (for purposes of this Section 11.1.3 a
material failure to perform or comply shall be deemed to be a failure which has,
either individually or in the aggregate, a Material Adverse Effect on the party
so failing or on the business, operations, financial condition, property or
assets of the combined enterprise or which materially adversely affects
consummation of the Merger and the other transactions contemplated hereby;

         11.1.4 At the election of either Westbank or Cargill, if the Closing
shall not have occurred on or before March 31, 1999 (the "Termination Date"), or
such later date as shall have been agreed to in writing by Westbank and Cargill;
provided, that no party may terminate this Agreement pursuant to this Section
11.1.4 if the failure of the Closing to have occurred on or before said date was
due to such party's breach of any of its obligations under this Agreement;

         11.1.5 By either Cargill or Westbank if the stockholders of Cargill
shall have voted at its stockholders meeting on the transactions contemplated by
this Agreement and such vote shall not have been sufficient to approve such
transactions;

         11.1.6 By either Cargill or Westbank (i) if final action has been taken
by a regulatory authority whose approval is required in connection with this
Agreement and the transactions contemplated hereby, which final action (x) has
become unappealable and (y) does not approve this Agreement or the transactions
contemplated hereby, or (ii) if any court of competent jurisdiction or other
governmental authority shall have issued an order, decree, ruling or taken any
other action restraining, enjoining or otherwise prohibiting the Merger and such
order, decree, ruling or other action shall have become final and nonappealable;

         11.1.7 By Cargill, if its Board of Directors so determines by a vote of
a majority of the members of its entire Board, on the Determination Date, if the
Westbank Market Value shall be less than $12.00 per share, subject, however, to
the following: If Cargill elects to exercise its termination right pursuant to
this Section 11.1.7, it shall give written notice to Westbank during the
three-day period commencing with its receipt of such notice, Westbank shall have
the option to increase the Merger Consideration by adjusting the Exchange Ratio
(calculated to the nearest one ten-thousandth) to equal the number obtained by
dividing (A) $17.00 per share by (B) the Westbank Market Value. If Westbank so
elects within such three-day period, it shall give prompt written notice to
Cargill of such election and the revised Exchange Ratio, whereupon no
termination shall have occurred pursuant to this Section 11.1.7 and this
Agreement shall remain in effect in accordance with its terms (except as the
Exchange Ratio shall have been so modified).

         For purposes of this Agreement, the following terms shall have the
meanings indicated:

                  "Westbank Market Value" shall mean the average of the closing
         prices of a share of Westbank Common Stock on the Nasdaq Stock Market's
         National Market during the period of 20 consecutive trading days ending
         on the fifth trading day prior to the Determination Date, rounded to
         the nearest whole cent.

                  "Determination Date" shall mean the date on which the last
         required approval of a governmental entity is obtained with respect to
         the Merger without regard to any requisite waiting period in respect
         thereof, except if the Effective Date does not occur on or before the
         sixteenth day following the last regulatory approval solely because of
         the non- expiration of waiting periods, then it shall mean the date
         five business days before the Effective Date.

                                      -42-

         11.2 EFFECT OF TERMINATION.

         11.2.1 In the event of termination of this Agreement pursuant to any
provision of Section 11.1, this Agreement shall forthwith become void and have
no further force, except that the provisions of any Section which, by its terms,
relates to post-termination rights or obligations, shall survive such
termination of this Agreement and remain in full force and effect.

         11.2.2 If this Agreement is terminated, expenses and damages of the
parties hereto shall be determined as follows:

                  (a) Termination of this Agreement pursuant to Section 11.1
(other than termination pursuant to Sections 11.1.2 and 11.1.3 as a result of a
willful breach or gross negligence by a party hereto) shall be without
liability, cost or expense on the part of any party to the other.

                  (b) In the event of a termination of this Agreement pursuant
to Section 11.1.2 or 11.1.3 hereof resulting from the willful conduct or gross
negligence of a party, such party shall be obligated to reimburse the other
party for up to $150,000 of out-of-pocket costs and expenses, including, without
limitation, reasonable legal, accounting and investment banking fees and
expenses, incurred by such other party in connection with the entering into of
this Agreement and the carrying out of any and all acts contemplated hereunder
(collectively referred to as "Costs"). The payment of Costs is not an exclusive
remedy, but is in addition to the Options to be granted pursuant to the Stock
Option Agreement attached as Exhibit C, any other rights or remedies available
to the parties hereto at law or in equity or as is contemplated herein.

         11.2.3 Except as provided in Sections 11.2.2, whether or not the Merger
is consummated, all Costs incurred in connection with this Agreement and the
transactions contemplated hereby shall be borne by the party incurring such
costs and expenses.

Cargill Subsidiary, Westbank or any Westbank Subsidiary, be personally liable
thereunder for any default by any party in any of its obligations hereunder
unless any such default was intentionally caused by such officer, agent or
director.

         11.3 NON-EXCLUSIVITY OF REMEDY. Notwithstanding anything to the
contrary set forth in this Agreement or in the Stock Option Agreement attached
as Exhibit C, the parties may pursue any remedy at law or in equity in the event
of termination for any reasons which involve wilful misconduct or gross
negligence.

(b) extend the time for the performance of any of the obligations or other acts
of any other party hereto, (c) waive any inaccuracies in the representations and
warranties contained herein or in any document delivered pursuant hereto, or (d)
waive compliance with any of the agreements or conditions contained herein;
provided, however, that after any approval of this Agreement and the
transactions contemplated hereby by the stockholders of Cargill, there may not
be, without further approval of such stockholders, any amendment of this
Agreement which reduces the amount or changes the form of consideration to be
delivered to Cargill's stockholders pursuant to this Agreement. This Agreement
may not be amended except by an instrument in writing signed on behalf of each
of the parties hereto. Any agreement on the part of a party hereto to any
extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such party, but such waiver or

                                      -43-

   196



failure to insist on strict compliance with such obligation, covenant, agreement

subsequent or other failure.

         The undersigned intend to be legally bound hereby.

         Sincerely,
   203
                                                                     Exhibit B-1

Members of the Board:

         You have requested our opinion as to the fairness, from a financial
point of view, of the terms of an Agreement and Plan of Merger dated July 14,
1998 (the "Merger Agreement"), by and among Westbank Corporation. ("Westbank")
and its principal subsidiary Parkwest Bank and Trust Company, and Cargill
Bancorp, Inc. ("Cargill") and its principal subsidiary Cargill Bank, to the
holders of Cargill Common Stock, $.01 par value, ("Cargill Common Stock").

         Pursuant to the terms of the Merger Agreement, Cargill will be acquired
by Westbank through the merger of Cargill with and into Westbank (the "Merger").
The Merger Agreement provides that each outstanding share of Cargill Common
Stock shall be converted automatically into and be exchangeable for shares of
Westbank common stock in accordance with the Exchange Ratio (rounded to the
nearest ten thousandth of a share). The Exchange Ratio shall be (i) if the
Westbank Market Value is greater than or equal to $13.07, then 1.3008 fully paid
and nonassessable shares of Westbank common stock; (ii) if the Westbank Market
Value is less than $13.07 but greater than or equal to $12.00, then the number
of fully paid and nonassessable shares of Westbank common stock obtained by
dividing (A) $17.00 per share by (B) the Westbank Market Value; and (iii) if
Westbank Market Value is less than $12.00, then 1.4167 fully paid and
nonassessable shares of Westbank common stock , subject to adjustment as
provided in the in Section 11.1.7 of the Agreement.

         In connection with executing the Merger Agreement, Cargill entered into
an Option Agreement dated July 14, 1998 ("the Option Agreement"), pursuant to
which Cargill has granted Westbank an option to acquire up to 84,804 fully paid
and nonassessable shares of Cargill Common Stock at a price of $12.00 per share;
provided further that in no event shall the number of shares of Cargill Common
Stock for which this Option is exercisable exceed 19.9% of the Cargill's issued
and outstanding shares of common stock after giving effect to any shares subject
to or issued pursuant to the Option Agreement. Westbank may exercise this option
upon the occurrence of certain events specified in the Option Agreement.

         Ostrowski & Company, Inc., as part of its bank and thrift advisory
business, is regularly engaged in the valuation of financial institutions and
their securities in connection with mergers and acquisitions and other corporate
purposes. We are familiar with Cargill and have received and will receive fees
from Cargill for issuing an opinion as to the fairness, from a financial point
of view, of the terms of the proposed transaction as set forth in the Merger
Agreement.

         In connection with providing this opinion, we have examined and relied
upon, among other things: the Merger Agreement; annual reports to shareholders,
proxy statements and related audited financial statements for Cargill for each
of the three fiscal years ended September 30, 1995, 1996 and 1997; certain
unaudited interim financial reports for Cargill for the quarters ended December
31, 1997 March 31, 1998 and June 30, 1998, certain other financial information
for Cargill, including proforma financial statements and management's estimates
relating to, among other things, earnings, asset quality, loan delinquencies and
capital; annual reports to shareholders, proxy statements and related audited
financial statements for Westbank for each of the three fiscal years ended
December 31, 1995, 1996 and 1997; certain unaudited interim financial reports
for Westbank for the quarter ended March 31, 1998, certain other financial
information for Westbank, including proforma financial statements and
management's estimates relating to, among other things, earnings, asset quality,
loan delinquencies and capital. We have conducted discussions with executive
management of Cargill and Westbank concerning historical financial performance
and condition, market area economic conditions, future business prospects and
financial forecasts. We have reviewed comparable financial, operating and market
data for the banking industry and selected peer groups; compared the terms of
the Merger Agreement with other bank and thrift merger and acquisition
transactions; and have considered such additional financial and other
information deemed relevant.

         In preparing our opinion, we have relied upon the accuracy,
completeness and fair presentation of all information supplied or otherwise made
available to us by, or on behalf of, Cargill and Westbank. We have not
independently verified such information or undertaken an independent evaluation
or appraisal of the assets or liabilities of Cargill or Westbank, nor have we
been furnished any such evaluations or appraisals. With respect to forecasts of
expected future financial performance, we have been advised that they reflect
the best currently available estimates and judgement of the executive
management. This opinion is necessarily based upon the information available to
us and the market, economic and other conditions, as they exist and can be
evaluated, as of the date of this letter.

         This opinion is directed solely to the fairness, from a financial point
of view, of the terms of the Merger Agreement to Cargill Shareholders and does
not constitute a recommendation to any Cargill Shareholder as to how such
Cargill Shareholder should vote with respect to the Merger Agreement.

         In reliance upon and subject to the foregoing, it is our opinion that
as of the date hereof, the terms of the Merger Agreement are fair, from a
financial point of view, to Cargill Shareholders.

                                                   Very truly yours,

The Board of Directors
Westbank Corporation
225 Park Avenue
West Springfield, MA 01089

Members of the Board:

         You have requested our opinion as to the fairness, from a financial
point of view, to the shareholders of Westbank Corporation ("Westbank") of the
Exchange Ratio (as defined below) in the proposed merger (the "Merger") of
Cargill Bancorp, Inc. ("Cargill"), with and into Westbank, pursuant to the
Affiliation and Merger Agreement (the "Merger Agreement") dated July 15, 1998.

         Under the terms of, and subject to certain conditions as defined in the
Merger Agreement, each issued and outstanding share of common stock, $0.01 par
value, of Cargill, except for any dissenting shares and except for any shares
held by Westbank will be entitled to receive Merger Consideration payable in
shares of common stock, $2.00 par value per share, of Westbank Corporation
("Westbank Common Stock"). The Merger Consideration will be based on the average
of the closing prices per share of Westbank Common Stock during the twenty
consecutive trading day period ending on the fifth trading day immediately
preceding the Determination Date (the "Westbank Market Value"). The exchange
ratio will be equal to 1.3008 shares of Westbank Common Stock, subject to the
adjustments described below (the "Exchange Ratio").

         If the Westbank Market Value is greater than $13.07, then Cargill
shareholders shall receive an Exchange Ratio of 1.3008 shares of Westbank Common
Stock for each share of Cargill stock. If the Westbank Market Value is less than
$13.07 but greater than or equal to $12.00, then Cargill shareholders shall
receive an Exchange Ratio equal to $17.00 divided by the Westbank Market Value.
If the Westbank Market Value is less than $12.00, then Cargill shall have the
right to terminate the Merger, provided however, that Westbank shall have the
option to increase the Exchange Ratio above 1.4167 as provided in the Merger
Agreement.

         Northeast Capital & Advisory, Inc., as part of its investment banking
business, is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated

negotiations leading to, the Merger Agreement. We also have provided investment
banking services to Westbank since 1989.

                                                         Fairness Opinion Letter
                                                                        Page - 2


         In connection with this opinion, we have reviewed, among other things,
the Merger Agreement; the Annual Reports of Cargill for the three years ended
September 30, 1997; the Annual Report to Shareholders on Form 10-K of Westbank
for the year ending December 31, 1997; certain Quarterly Reports of Cargill and
Westbank; certain unaudited interim reports and certain press releases to the
respective shareholders of Westbank and Cargill; and financial information
concerning the business and operations of Westbank and Cargill furnished to us
by their respective managements. We also have conducted discussions with members
of the senior managements of Westbank and Cargill regarding the past and current
business operations, regulatory relationships, financial condition and future
prospects of their respective companies. In addition, we have reviewed the
reported price and trading activity of Cargill's and Westbank's common stock;
compared certain financial information for Westbank and Cargill with certain
financial and stock market information for certain other companies, the
securities of which are publicly traded; reviewed the financial terms of certain
recent business combinations in the commercial banking environment in
particular; and performed such other studies and analyses as we considered
appropriate.

         In conducting our review and arriving at our opinion, we relied upon
and assumed the accuracy and completeness of all of the financial and other
information provided to us or publicly available and we have not attempted
independently to verify such information. We have generally relied upon the
management of Westbank and Cargill as to the reasonableness and achievability of
the financial and operating forecasts and projections (and the assumptions and
bases therefor) provided to us, and we have generally assumed that such
forecasts and projections reflect the best currently available estimates and
judgments of such managements and that such forecasts and projections will
generally be realized in the amounts and in the time periods currently estimated
by such managements. We have also assumed that the aggregate allowance for loan
losses for Westbank and Cargill is adequate to cover such losses. We have not
made nor obtained any evaluations or appraisals of the property of Westbank and
Cargill. We have, however, independently examined certain individual loan credit
files of Cargill and independently produced projections and operating forecasts
to assure ourselves that the assumptions generated by management of Westbank and
Cargill in their projections and forecasts do not materially and adversely alter
the adequacy of the financial consideration being exchanged by Westbank
shareholders, from a financial point of view. Finally, you have informed us
that, while not a condition to the transaction, the Merger is intended to be
accounted for as a pooling of interests transaction under generally accepted
accounting principles.

         In conducting our analysis and arriving at our opinion as expressed
herein, we have considered such financial and other factors as we have deemed
appropriate in the circumstances. We have also taken into account our assessment
of general economic, market and financial conditions, our experience in other
transactions, and our knowledge of the banking industry in general. In rendering
our opinion, we have assumed that in the course of obtaining the necessary
regulatory approvals for the Merger, no conditions will be imposed that will
have a material adverse effect on the contemplated benefits of the Merger to
Westbank. Our opinion is based upon information, conditions and projections as
they exist and can be evaluated on the date hereof.

         Based upon and subject to the foregoing, it is our opinion that the
Exchange Ratio of the Merger as provided and described in the Merger Agreement
is fair, from a financial point of view, to Westbank and its shareholders.

                             STOCK OPTION AGREEMENT

                  THE TRANSFER OF THIS AGREEMENT IS SUBJECT TO
                   CERTAIN PROVISIONS CONTAINED HEREIN AND TO
        RESALE RESTRICTIONS UNDER THE SECURITIES ACT OF 1933, AS AMENDED
              STOCK OPTION AGREEMENT, dated July 15, 1998, between
                      CARGILL BANCORP, INC. ("Issuer") and
                        WESTBANK CORPORATION ("Grantee").

                              W I T N E S S E T H:

         WHEREAS, Grantee and Issuer have entered into an Affiliation and Merger
Agreement of even date herewith (the "Merger Agreement"), which agreement has
been executed by the parties hereto immediately prior to this Agreement; and

         WHEREAS, as a condition to Grantee's entering into the Merger Agreement
and in consideration therefor, Issuer has agreed to grant Grantee the Option (as
hereinafter defined):

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements set forth herein and in the Merger Agreement, the
parties hereto agree as follows:

         1. (a) Issuer hereby grants to Grantee an unconditional, irrevocable
option (the "Option") to purchase, subject to the terms hereof, up to 84,804
fully paid and nonassessable shares of Issuer's Common Stock ("Common Stock"),
at a price of $12.00 per share (the "Option Price"); provided further that in no
event shall the number of shares of Common Stock for which this Option is
exercisable exceed 19.9% of the Issuer's issued and outstanding shares of Common
Stock after giving effect to any shares subject to or issued pursuant to the
Option or other employee stock options. The number of shares of Common Stock
that may be received upon the exercise of the Option and the Option Price are
subject to adjustment as herein set forth.

         (b) In the event that any additional shares of Common Stock are issued
or otherwise become outstanding after the date of this Agreement (other than
pursuant to this Agreement), the number of shares of Common Stock subject to the
Option shall be increased so that, after such issuance, it equals 19.9% of the
number of shares of Common Stock then issued and outstanding giving effect to
any shares subject or issued pursuant to the Option or other employee stock
options. Nothing contained in this Section 1(b) or elsewhere in this Agreement
shall be deemed to authorize Issuer or Grantee to breach any provision of the
Merger Agreement.

         2. (a) The Holder (as hereinafter defined) may exercise the Option, in
whole or part, and from time to time, if, but only if, both an Initial
Triggering Event (as hereinafter defined) and a Subsequent Triggering Event (as
hereinafter defined) shall have occurred prior to the occurrence of an Exercise
Termination Event (as hereinafter defined), provided that the Holder shall have
sent the written notice of such exercise (as provided in subsection (e) of this
Section 2) within 90 days following such Subsequent Triggering Event. Each of
the following shall be an Exercise Termination Event: (i) the Effective Time of
the Merger; (ii) termination of the Merger Agreement in accordance with the
provisions thereof if such termination occurs prior to the occurrence of an
Initial Triggering Event except a termination by Grantee pursuant to Section
11.1.2 or 11.1.3 of the Merger Agreement (unless the breach by Issuer giving
rise to such right of termination is non-volitional); or (iii) the passage of
eighteen months after termination of the Merger Agreement if such termination
follows the occurrence of an Initial Triggering Event or is a


                                      -1-
   210
termination by Grantee pursuant to Section 11.1.2 or 11.1.3 of the Merger
Agreement (unless the breach by Issuer giving rise to such right of termination
is non-volitional) (provided that if an Initial Triggering Event continues or
occurs beyond such termination and prior to the passage of such month period,
the Exercise Termination Event shall be eighteen months from the expiration of
the Last Triggering Event but in no event more than eighteen months after such
termination). The "Last Triggering Event" shall mean the last Initial Triggering
Event to expire. The term "Holder" shall mean the holder or holders of the
Option.

         (b) The term "Initial Triggering Event" shall mean any of the following
events or transactions occurring after the date hereof:

                  (i) Issuer or any of its Subsidiaries (each an "Issuer
         Subsidiary"), without having received Grantee's prior written consent,
         shall have entered into an agreement to engage in an Acquisition
         Transaction (as hereinafter defined) with any person (the term "person"
         for purposes of this Agreement having the meaning assigned thereto in
         Sections 3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934,
         as amended (the "1934 Act"),and the rules and regulations thereunder)
         other than Grantee or any of its Subsidiaries (each a "Grantee
         Subsidiary") or the Board of Directors of Issuer shall have recommended
         that the stockholders of Issuer approve or accept any Acquisition
         Transaction. For purposes of this Agreement,"Acquisition Transaction"
         shall mean (w) a merger or consolidation, or any similar transaction,
         involving Issuer or any Significant Subsidiary (as defined in Rule 1-02
         of Regulation S-X promulgated by the Securities and Exchange Commission
         (the "SEC")) of Issuer, (x) a purchase, lease or other acquisition of
         all or a substantial portion of the assets of Issuer or any Significant
         Subsidiary of Issuer, (y) a purchase or other acquisition (including by
         way of merger, consolidation, share exchange or otherwise) of
         securities representing 10% or more of the voting power of Issuer or
         any Significant Subsidiary of Issuer, or (z) any substantially similar
         transaction; provided, however, that in no event shall any (i) merger,
         consolidation or similar transaction involving Issuer or any
         Significant Subsidiary in which the voting securities of Issuer
         outstanding immediately prior thereto continue to represent (by either
         remaining outstanding or being converted into the voting securities of
         the surviving entity of any such transaction) at least 80% of the
         combined voting power of the voting securities of the Issuer or the
         surviving entity outstanding immediately after the consummation of such
         merger, consolidation, or similar transaction, or (ii) any merger,
         consolidation, purchase or similar transaction involving only the
         Issuer and one or more of its Subsidiaries or involving only any two or
         more of such Subsidiaries, be deemed to be an Acquisition Transaction,
         provided any such transaction is not entered into in violation of the
         terms of the Merger Agreement;

                  (ii) Issuer or any Issuer Subsidiary, without having received
         Grantee's prior written consent, shall have authorized, recommended,
         proposed or publicly announced its intention to authorize, recommend or
         propose, to engage in an Acquisition Transaction with any person other
         than Grantee or a Grantee Subsidiary, or the Board of Directors of
         Issuer shall have publicly withdrawn or modified, or publicly announced
         its intent to withdraw or modify, in any manner adverse to Grantee, its
         recommendation that the stockholders of Issuer approve the transactions
         contemplated by the Merger Agreement;

                  (iii) Any person other than Grantee, any Grantee Subsidiary or
         any Issuer Subsidiary acting in a fiduciary capacity in the ordinary
         course of its business shall have acquired beneficial ownership or the
         right to acquire beneficial ownership of 10% or more of the outstanding
         shares of Common Stock (the term "beneficial ownership" for purposes of
         this Option Agreement having the meaning assigned thereto in Section
         13(d) of the 1934 Act, and the rules and regulations thereunder);


                                      -2-
   211
                  (iv) Any person other than Grantee or any Grantee Subsidiary
         shall have made a bona fide proposal to Issuer or its stockholders by
         public announcement or written communication that is or becomes the
         subject of public disclosure to engage in an Acquisition Transaction;

                  (v) After an overture is made by a third party to Issuer or
         its stockholders to engage in an Acquisition Transaction, Issuer shall
         have breached any covenant or obligation contained in the Merger
         Agreement and such breach (x) would entitle Grantee to terminate the
         Merger Agreement and (y) shall not have been cured prior to the Notice
         Date (as defined below); or

                  (vi) Any person other than Grantee or any Grantee Subsidiary,
         other than in connection with a transaction to which Grantee has given
         its prior written consent, shall have filed (or in the case of an
         application which is filed prior to the execution of this Stock Option
         Agreement, the failure to have said application withdrawn or denied
         within thirty days) an application or notice with the Federal Reserve
         Board, or other federal or state bank regulatory authority, which
         application or notice has been accepted for processing, for approval to
         engage in an Acquisition Transaction.

         (c) The term "Subsequent Triggering Event" shall mean either of the
following events or transactions occurring after the date hereof:

                  (i) The acquisition by any person of beneficial ownership of
         15% or more of the then outstanding Common Stock; or

                  (ii) The occurrence of the Initial Triggering Event described
         in clause (i) of subsection (b) of this Section 2, except that the
         percentage referred to in clause (y) shall be 10.01%.

         (d) Issuer shall notify Grantee promptly in writing of the occurrence
of any Initial Triggering Event or Subsequent Triggering Event (together, a
"Triggering Event"), it being understood that the giving of such notice by
Issuer shall not be a condition to the right of the Holder to exercise the
Option.

         (e) In the event the Holder is entitled to and wishes to exercise the
Option, it shall send to Issuer a written notice (the date of which being herein
referred to as the "Notice Date") specifying (i) the total number of shares it
will purchase pursuant to such exercise and (ii) a place and date not earlier
than three business days nor later than 30 business days from the Notice Date
for the closing of such purchase (the "Closing Date"); provided that if prior
notification to or approval of the Federal Reserve Board or any other regulatory
agency is required in connection with such purchase, the Holder shall promptly
file the required notice or application for approval and shall expeditiously
process the same and the period of time that otherwise would run pursuant to
this sentence shall run instead from the date on which any required notification
periods have expired or been terminated or such approvals have been obtained and
any requisite waiting period or periods shall have passed. Any exercise of the
Option shall be deemed to occur on the Notice Date relating thereto.

         (f) At the closing referred to in subsection (e) of this Section 2, the
Holder shall pay to Issuer the aggregate purchase price for the shares of Common
Stock purchased pursuant to the exercise of the Option in immediately available
funds by wire transfer to a bank account designated by Issuer, provided that
failure or refusal of Issuer to designate such a bank account shall not preclude
the Holder from exercising the Option.


                                      -3-
   212
         (g) At such closing, simultaneously with the delivery of immediately
available funds as provided in subsection (f) of this Section 2, Issuer shall
deliver to the Holder a certificate or certificates representing the number of
shares of Common Stock purchased by the Holder and, if the Option should be
exercised in part only, a new Option evidencing the rights of the Holder thereof
to purchase the balance of the shares purchasable hereunder, and the Holder
shall deliver to Issuer a copy of this Agreement and a letter agreeing that the
Holder will not offer to sell or otherwise dispose of such shares in violation
of applicable law or the provisions of this Agreement.

         (h) Certificates for Common Stock delivered at a closing hereunder may
be endorsed with a restrictive legend that shall read substantially as follows:

         "The transfer of the shares represented by this certificate is subject
         to certain provisions of an agreement between the registered holder
         hereof and Issuer and to resale restrictions arising under the
         Securities Act of 1933, as amended. A copy of such agreement is on file
         at the principal office of Issuer and will be provided to the holder
         hereof without charge upon receipt by Issuer of a written request
         therefor."

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "1933 Act"), in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if the Holder shall have delivered to Issuer a copy of a letter from the staff
of the SEC, or an opinion of counsel, in form and substance reasonably
satisfactory to Issuer, to the effect that such legend is not required for
purposes of the 1933 Act; (ii) the reference to the provisions to this Agreement
in the above legend shall be removed by delivery of substitute certificate(s)
without such reference if the shares have been sold or transferred in compliance
with the provisions of this Agreement and under circumstances that do not
require the retention of such reference; and (iii) the legend shall be removed
in its entirety if the conditions in the preceding clauses (i) and (ii) are both
satisfied. In addition, such certificates shall bear any other legend as may be
required by law.

         (i) Upon the giving by the Holder to Issuer of the written notice of
exercise of the Option provided for under subsection (e) of this Section 2 and
the tender of the applicable purchase price in immediately available funds, the
Holder shall be deemed to be the holder of record of the shares of Common Stock
issuable upon such exercise, notwithstanding that the stock transfer books of
Issuer shall then be closed or that certificates representing such shares of
Common Stock shall not then be actually delivered to the Holder. Issuer shall
pay all expenses, and any and all United States federal, state and local taxes
and other charges that may be payable in connection with the preparation, issue
and delivery of stock certificates under this Section 2 in the name of the
Holder or its assignee, transferee or designee.

         3. Issuer agrees: (i) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued or treasury shares of
Common Stock so that the Option may be exercised without additional
authorization of Common Stock after giving effect to all other options,
warrants, convertible securities and other rights to purchase Common Stock; (ii)
that it will not, by charter amendment or through reorganization, consolidation,
merger, dissolution or sale of assets, or by any other voluntary act, avoid or
seek to avoid the observance or performance of any of the covenants,
stipulations or conditions to be observed or performed hereunder by Issuer;
(iii) promptly to take all action as may from time to time be required
(including (x) complying with all premerger notification, reporting and waiting
period requirements specified in 15 U.S.C. Section 18a and regulations
promulgated thereunder and (y) in the event, under the Bank Holding Company Act
of 1956, as amended (the "BHCA"), or the Change in Bank Control Act of 1978, as
amended, or any state banking law, prior approval of or notice to the Federal
Reserve Board or to any state regulatory authority is necessary before the
Option may be exercised, cooperating fully with the Holder in preparing such
applications or notices and providing such information to the Federal Reserve
Board or such state regulatory authority as they may require) in order to permit
the Holder to exercise the Option and Issuer duly and effectively to issue
shares of Common Stock pursuant hereto; and (iv) promptly to take all action
provided herein to protect the rights of the Holder against dilution.


                                      -4-
   213
         4. This Agreement (and the Option granted hereby) are exchangeable,
without expense, at the option of the Holder, upon presentation and surrender of
this Agreement at the principal office of Issuer, for other Agreements providing
for Options of different denominations entitling the holder thereof to purchase,
on the same terms and subject to the same conditions as are set forth herein, in
the aggregate the same number of shares of Common Stock purchasable hereunder.
The terms "Agreement" and "Option" as used herein include any Stock Option
Agreements and related Options for which this Agreement (and the Option granted
hereby) may be exchanged. Upon receipt by Issuer of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this
Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date. Any such new Agreement executed and delivered shall constitute
an additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed or mutilated shall at any time be
enforceable by anyone.

         5. In addition to the adjustment in the number of shares of Common
Stock that are purchasable upon exercise of the Option pursuant to Section 1 of
this Agreement, the number of shares of Common Stock purchasable upon the
exercise of the Option and the Option Price shall be subject to adjustment from
time to time as provided in this Section 5. In the event of any change in, or
distributions in respect of, the Common Stock by reason of stock dividends,
split-ups, mergers, recapitalization, combinations, subdivisions, conversions,
exchanges of shares, distributions on or in respect of the Common Stock that
would be prohibited under the terms of the Merger Agreement, or the like, the
type and number of shares of Common Stock purchasable upon exercise hereof and
the Option Price shall be appropriately adjusted in such manner as shall fully
preserve the economic benefits provided hereunder and proper provision shall be
made in any agreement governing any such transaction to provide for such proper
adjustment and the full satisfaction of the Issuer's obligations hereunder.

         6. Upon the occurrence of a Subsequent Triggering Event that occurs
prior to an Exercise Termination Event, Issuer shall, at the request of Grantee
deliver within 90 days of such Subsequent Triggering Event (whether on its own
behalf or on behalf of any subsequent holder of this Option (or part thereof) or
any of the shares of Common Stock issued pursuant hereto), promptly prepare,
file and keep current a shelf registration statement under the 1933 Act covering
this Option and any shares issued and issuable pursuant to this Option and shall
use its reasonable best efforts to cause such registration statement to become
effective and remain current in order to permit the sale or other disposition of
this Option and any shares of Common Stock issued upon total or partial exercise
of this Option ("Option Shares") in accordance with any plan of disposition
requested by Grantee. Issuer will use its reasonable best efforts to cause such
registration statement first to become effective and then to remain effective
for such period not in excess of 180 days from the day such registration
statement first becomes effective or such shorter time as may be reasonably
necessary to effect such sales or other dispositions. Grantee shall have the
right to demand only one such registration. The foregoing notwithstanding, if,
at the time of any request by Grantee for registration of the Option or Option
Shares as provided above, Issuer is in registration with respect to an
underwritten public offering of shares of Common Stock, and if in the good faith
judgment of the managing underwriter or managing underwriters, or, if none, the
sole underwriter or underwriters, of such offering the inclusion of the Holder's
Option or Option Shares would interfere with the successful marketing of the
shares of Common Stock offered by Issuer, the number of Option Shares otherwise
to be covered in the registration statement contemplated hereby may be reduced;
and provided, however, that after any such required reduction the number of
Option Shares to be included in such offering for the account of the Holder
shall constitute at least 25% of the total number of shares to be sold by the
Holder and Issuer in the aggregate; and provided further, however, that if such
reduction occurs, then the Issuer shall file a registration statement for the
balance as promptly as practical and no reduction shall thereafter occur. Each
such Holder shall provide all information reasonably requested by Issuer for
inclusion in any registration statement to be filed hereunder. If requested by
any such Holder in connection with such registration, Issuer shall become a
party to any underwriting agreement relating to the sale of such shares, but
only to the extent of obligating itself in respect of representations,


                                      -5-
   214
warranties, indemnities and other agreements customarily included in such
underwriting agreements for the Issuer. Upon receiving any request under this
Section 6 from any Holder, Issuer agrees to send a copy thereof to any other
person known to Issuer to be entitled to registration rights under this Section
6, in each case by promptly mailing the same, postage prepaid, to the address of
record of the persons entitled to receive such copies. Notwithstanding anything
to the contrary contained herein, in no event shall Issuer be obligated to
effect more than one registration pursuant to this Section 6 by reason of the
fact that there shall be more than one Grantee as a result of any assignment or
division of this Agreement.

         7. (a) Immediately prior to the occurrence of a Repurchase Event (as
defined below), (i) following a request of the Holder, delivered prior to an
Exercise Termination Event, Issuer (or any successor thereto) shall repurchase
the Option from the Holder at a price (the "Option Repurchase Price") equal to
the amount by which (A) the market/offer price (as defined below) exceeds (B)
the Option Price, multiplied by the number of shares for which this Option may
then be exercised and (ii) at the request of the owner of Option Shares from
time to time (the "Owner"), delivered within 90 days of such occurrence (or such
later period as provided in Section 10), Issuer shall repurchase such number of
the Option Shares from the Owner as the Owner shall designate at a price (the
"Option Share Repurchase Price") equal to the market/offer price multiplied by
the number of Option Shares so designated. The term "market/offer price" shall
mean the highest of (i) the price per share of Common Stock at which a tender
offer or exchange offer therefor has been made, (ii) the price per share of
Common Stock to be paid by any third party pursuant to an agreement with Issuer,
(iii) the highest closing price for shares of Common Stock within the six-month
period immediately preceding the date the Holder gives notice of the required
repurchase of this Option or the Owner gives notice of the required repurchase
of Option Shares, as the case may be, or (iv) in the event of a sale of all or a
substantial portion of Issuer's assets, the sum of the price paid in such sale
for such assets and the current market value of the remaining assets of Issuer
as determined by a nationally recognized investment banking firm selected by the
Holder or the Owner, as the case may be, divided by the number of shares of
Common Stock of Issuer outstanding at the time of such sale. In determining the
market/offer price, the value of consideration other than cash shall be
determined by a nationally recognized investment banking firm selected by the
Holder or Owner, as the case may be and reasonably acceptable to the Issuer.

         (b) The Holder and the Owner, as the case may be, may exercise its
right to require Issuer to repurchase the Option and any Option Shares pursuant
to this Section 7 by surrendering for such purpose to Issuer, at its principal
office, a copy of this Agreement or certificates for Option Shares, as
applicable, accompanied by a written notice or notices stating that the Holder
or the Owner, as the case may be, elects to require Issuer to repurchase this
Option and/or the Option Shares in accordance with the provisions of this
Section 7, with the latter to occur within (x) five business days after the
surrender of the Option and/or certificates representing Option Shares and the
receipt of such notice or notices relating thereto and (y) the time that is
immediately prior to the occurrence of a Repurchase Event, Issuer shall deliver
or cause to be delivered to the Holder the Option Repurchase Price and/or to the
Owner the Option Share Repurchase Price therefor or the portion thereof that
Issuer is not then prohibited under applicable law and regulation from so
delivering.

         (c) To the extent that Issuer is prohibited under applicable law or
regulation from repurchasing the Option and/or the Option Shares in full, Issuer
shall immediately so notify the Holder and/or the Owner and thereafter deliver
or cause to be delivered, from time to time, to the Holder and/or the Owner, as
appropriate, the portion of the Option Repurchase Price and the Option Share
Repurchase Price, respectively, that it is no longer prohibited from delivering,
within five business days after the date on which Issuer is no longer so
prohibited; provided, however, that if Issuer at any time after delivery of a
notice of repurchase pursuant to paragraph (b) of this Section 7 is prohibited
under applicable law or regulation from delivering to the Holder and/or the
Owner, as appropriate, the Option Repurchase Price and the Option Share
Repurchase Price, respectively, in full (and Issuer hereby undertakes to use its
best


                                      -6-
   215
efforts to obtain all required regulatory and legal approvals and to file any
required notices as promptly as practicable in order to accomplish such
repurchase), the Holder or Owner may revoke its notice of repurchase of the
Option or the Option Shares either in whole or to the extent of the prohibition,
whereupon, in the latter case, Issuer shall promptly (i) deliver to the Holder
and/or the Owner, as appropriate, that portion of the Option Repurchase Price or
the Option Share Repurchase Price that Issuer is not prohibited from delivering;
and (ii) deliver, as appropriate, either (A) to the Holder, a new Stock Option
Agreement evidencing the right of the Holder to purchase that number of shares
of Common Stock obtained by multiplying the number of shares of Common Stock for
which the surrendered Stock Option Agreement was exercisable at the time of
delivery of the notice of repurchase by a fraction, the numerator of which is
the Option Repurchase Price less the portion thereof theretofore delivered to
the Holder and the denominator of which is the Option Repurchase Price, or (B)
to the Owner, a certificate for the Option Shares it is then so prohibited from
repurchasing.

         (d) For purposes of this Section 7, a Repurchase Event shall be deemed
to have occurred (i) upon the consummation of any merger, consolidation or
similar transaction involving Issuer or any purchase, lease or other acquisition
of all or a substantial portion of the assets of Issuer, other than any such
transaction which would not constitute an Acquisition Transaction pursuant to
the proviso to Section 2(b)(i) hereof or (ii) upon the acquisition by any person
of beneficial ownership of 50% or more of the then outstanding shares of Common
Stock, provided that no such event shall constitute a Repurchase Event unless a
Subsequent Triggering Event shall have occurred prior to an Exercise Termination
Event. The parties hereto agree that Issuer's obligations to repurchase the
Option or Option Shares under this Section 7 shall not terminate upon the
occurrence of an Exercise Termination Event unless no Subsequent Triggering
Event shall have occurred prior to the occurrence of an Exercise Termination
Event.

         8. (a) In the event that prior to an Exercise Termination Event, Issuer
shall enter into an agreement (i) to consolidate with or merge into any person,
other than Grantee or one of its Subsidiaries, and shall not be the continuing
or surviving corporation of such consolidation or merger, (ii) to permit any
person, other than Grantee or one of its Subsidiaries, to merge into Issuer and
Issuer shall be the continuing or surviving corporation, but, in connection with
such merger, the then outstanding shares of Common Stock shall be changed into
or exchanged for stock or other securities of any other person or cash or any
other property or the then outstanding shares of Common Stock shall after such
merger represent less than 50% of the outstanding voting shares and voting share
equivalents of the merged company, or (iii) to sell or otherwise transfer all or
substantially all of its assets to any person, other than Grantee or one of its
Subsidiaries, then, and in each such case, the agreement governing such
transaction shall make proper provision so that the Option shall, upon the
consummation of any such transaction and upon the terms and conditions set forth
herein, be converted into, or exchanged for, an option (the "Substitute
Option"), at the election of the Holder, of either (x) the Acquiring Corporation
(as hereinafter defined) or (y) any person that controls the Acquiring
Corporation.

         (b) The following terms have the meanings indicated:

                  (1) "Acquiring Corporation" shall mean (i) the continuing or
         surviving corporation of a consolidation or merger with Issuer (if
         other than Issuer), (ii) Issuer in a merger in which Issuer is the
         continuing or surviving person, and (iii) the transferee of all or
         substantially all of Issuer's assets.

                  (2) "Substitute Common Stock" shall mean the common stock
         issued by the issuer of the Substitute Option upon exercise of the
         Substitute Option.

                  (3) "Assigned Value" shall mean the market/offer price, as
         defined in Section 7.


                                      -7-
   216
                  (4) "Average Price" shall mean the average closing price of a
         share of the Substitute Common Stock for the one year immediately
         preceding the consolidation, merger or sale in question, but in no
         event higher than the closing price of the shares of Substitute Common
         Stock on the day preceding such consolidation, merger or sale; provided
         that if Issuer is the issuer of the Substitute Option, the Average
         Price shall be computed with respect to a share of common stock issued
         by the person merging into Issuer or by any company which controls or
         is controlled by such person, as the Holder may elect.

         (c) The Substitute Option shall have the same terms as the Option,
provided, that if the terms of the Substitute Option cannot, for legal reasons,
be the same as the Option, such terms shall be as similar as possible and in no
event less advantageous to the Holder. The issuer of the Substitute Option shall
also enter into an agreement with the then Holder or Holders of the Substitute
Option in substantially the same form as this Agreement, which shall be
applicable to the Substitute Option.

         (d) The Substitute Option shall be exercisable for such number of
shares of Substitute Common Stock as is equal to the Assigned Value multiplied
by the number of shares of Common Stock for which the Option is then
exercisable, divided by the Average Price. The exercise price of the Substitute
Option per share of Substitute Common Stock shall then be equal to the Option
Price multiplied by a fraction, the numerator of which shall be the number of
shares of Common Stock for which the Option is then exercisable and the
denominator of which shall be the number of shares of Substitute Common Stock
for which the Substitute Option is exercisable.

         (e) In no event, pursuant to any of the foregoing paragraphs, shall the
Substitute Option be exercisable for more than 19.9% of the shares of Substitute
Common Stock outstanding prior to exercise of the Substitute Option. In the
event that the Substitute Option would be exercisable for more than 19.9% of the
shares of Substitute Common Stock outstanding prior to exercise but for this
clause (e), the issuer of the Substitute Option (the "Substitute Option Issuer")
shall make a cash payment to Holder equal to the excess of (i) the value of the
Substitute Option without giving effect to the limitation in this clause (e)
over (ii) the value of the Substitute Option after giving effect to the
limitation in this clause (e). This difference in value shall be determined by a
nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be, and reasonably acceptable to the Acquiring
Corporation.

         (f) Issuer shall not enter into any transaction described in subsection
(a) of this Section 8 unless the Acquiring Corporation and any person that
controls the Acquiring Corporation assume in writing all the obligations of
Issuer hereunder.

         9. (a) At the request of the holder of the Substitute Option (the
"Substitute Option Holder"), the issuer of the Substitute Option (the
"Substitute Option Issuer") shall repurchase the Substitute Option from the
Substitute Option Holder at a price (the "Substitute Option Repurchase Price")
equal to (x) the amount by which (i) the Highest Closing Price (as hereinafter
defined) exceeds (ii) the exercise price of the Substitute Option, multiplied by
the number of shares of Substitute Common Stock for which the Substitute Option
may then be exercised plus (y) Grantee's Out-of-Pocket Expenses (to the extent
not previously reimbursed), and at the request of the owner (the "Substitute
Share Owner") of shares of Substitute Common Stock (the "Substitute Shares"),
the Substitute Option Issuer shall repurchase the Substitute Shares at a price
(the "Substitute Share Repurchase Price") equal to (x) the Highest Closing Price
multiplied by the number of Substitute Shares so designated plus (y) Grantee's
Out-of-Pocket Expenses (to the extent not previously reimbursed). The term
"Highest Closing Price" shall mean the highest closing price for shares of
Substitute Common Stock within the six-month period immediately preceding the
date the Substitute Option Holder gives notice of the required repurchase of the
Substitute Option or the Substitute Share Owner gives notice of the required
repurchase of the Substitute Shares, as applicable.


                                      -8-
   217
         (b) The Substitute Option Holder and the Substitute Share Owner, as the
case may be, may exercise its respective right to require the Substitute Option
Issuer to repurchase the Substitute Option and the Substitute Shares pursuant to
this Section 9 by surrendering for such purpose to the Substitute Option Issuer,
at its principal office, the agreement for such Substitute Option (or, in the
absence of such an agreement, a copy of this Agreement) and certificates for
Substitute Shares accompanied by a written notice or notices stating that the
Substitute Option Holder or the Substitute Share Owner, as the case may be,
elects to require the Substitute Option Issuer to repurchase the Substitute
Option and/or the Substitute Shares in accordance with the provisions of this
Section 9. As promptly as practicable, and in any event within five business
days after the surrender of the Substitute Option and/or certificates
representing Substitute Shares and the receipt of such notice or notices
relating thereto, the Substitute Option Issuer shall deliver or cause to be
delivered to the Substitute Option Holder the Substitute Option Repurchase Price
and/or to the Substitute Share Owner the Substitute Share Repurchase Price
therefor or the portion thereof which the Substitute Option Issuer is not then
prohibited under applicable law and regulation from so delivering.

         (c) To the extent that the Substitute Option Issuer is prohibited under
applicable law or regulation from repurchasing the Substitute Option and/or the
Substitute Shares in part or in full, the Substitute Option Issuer shall
immediately so notify the Substitute Option Holder and/or the Substitute Share
Owner and thereafter deliver or cause to be delivered, from time to time, to the
Substitute Option Holder and/or the Substitute Share Owner, as appropriate, the
portion of the Substitute Share Repurchase Price, respectively, which it is no
longer prohibited from delivering, within five business days after the date on
which the Substitute Option Issuer is no longer so prohibited; provided,
however, that if the Substitute Option Issuer is at any time after delivery of a
notice of repurchase pursuant to subsection (b) of this Section 9 prohibited
under applicable law or regulation from delivering to the Substitute Option
Holder and/or the Substitute Share Owner, as appropriate, the Substitute Option
Repurchase Price and the Substitute Share Repurchase Price, respectively, in
full (and the Substitute Option Issuer shall use its best efforts to receive all
required regulatory and legal approvals as promptly as practicable in order to
accomplish such repurchase), the Substitute Option Holder or Substitute Share
Owner may revoke its notice of repurchase of the Substitute Option or the
Substitute Shares either in whole or to the extent of the prohibition,
whereupon, in the latter case, the Substitute Option Issuer shall promptly (i)
deliver to the Substitute Option Holder or Substitute Share Owner, as
appropriate, that portion of the Substitute Option Repurchase Price or the
Substitute Share Repurchase Price that the Substitute Option Issuer is not
prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the
Substitute Option Holder, a new Substitute Option evidencing the right of the
Substitute Option Holder to purchase that number of shares of the Substitute
Common Stock obtained by multiplying the number of shares of the Substitute
Common Stock for which the surrendered Substitute Option was exercisable at the
time of delivery of the notice of repurchase by a fraction, the numerator of
which is the Substitute Option Repurchase Price less the portion thereof
theretofore delivered to the Substitute Option Holder and the denominator of
which is the Substitute Option Repurchase Price, or (B) to the Substitute Share
Owner, a certificate for the Substitute Option Shares it is then so prohibited
from repurchasing.

         10. The 90-day period for exercise of certain rights under Sections 2,
6, 7 and 13 shall be extended: (i) to the extent necessary to obtain all
regulatory approvals for the exercise of such rights, and for the expiration of
all statutory waiting periods; and (ii) to the extent necessary to avoid
liability under Section 16(b) of the 1934 Act by reason of such exercise.

         11. Issuer hereby represents and warrants to Grantee as follows:

                  (a) Issuer has full corporate power and authority to execute
         and deliver this Agreement and to consummate the transactions
         contemplated hereby. The execution and delivery of this Agreement and
         the consummation of the transactions contemplated hereby have been duly
         and validly authorized by the Board of Directors of Issuer and no other
         corporate proceedings on the


                                      -9-
   218
         part of Issuer are necessary to authorize this Agreement or to
         consummate the transactions so contemplated. This Agreement has been
         duly and validly executed and delivered by Issuer.

                  (b) Issuer has taken all necessary corporate action to
         authorize and reserve and to permit it to issue, and at all times from
         the date hereof through the termination of this Agreement in accordance
         with its terms will have reserved for issuance upon the exercise of the
         Option, that number of shares of Common Stock equal to the maximum
         number of shares of Common Stock at any time and from time to time
         issuable hereunder, and all such shares, upon issuance pursuant hereto,
         will be duly authorized, validly issued, fully paid, nonassessable, and
         will be delivered free and clear of all claims, liens, encumbrance and
         security interests and not subject to any preemptive rights.

                  (c) Issuer has taken all action so that the entering into of
         this Option Agreement, the acquisition of shares of Common Stock
         hereunder and the other transactions contemplated hereby do not and
         will not result in the grant of any rights to any person.

         12. Grantee hereby represents and warrants to Issuer that:

                  (a) Grantee has all requisite corporate power and authority to
         enter into this Agreement and, subject to any approvals or consents
         referred to herein, to consummate the transactions contemplated hereby.
         The execution and delivery of this Agreement and the consummation of
         the transactions contemplated hereby have been duly authorized by all
         necessary corporate action on the part of Grantee. This Agreement has
         been duly executed and delivered by Grantee.

                  (b) The Option is not being, and any shares of Common Stock or
         other securities acquired by Grantee upon exercise of the Option will
         not be, acquired with a view to the public distribution thereof and
         will not be transferred or otherwise disposed of except in a
         transaction registered or exempt from registration under the Securities
         Act.

         13. Neither of the parties hereto may assign any of its rights or
obligations under this Option Agreement or the Option created hereunder to any
other person, without the express written consent of the other party, except
that in the event a Subsequent Triggering Event shall have occurred prior to an
Exercise Termination Event, Grantee, subject to the express provisions hereof,
may assign in whole or in part its rights and obligations hereunder within 90
days following such Subsequent Triggering Event (or such later period as
provided in Section 10); provided, however, that until the date 15 days
following the date on which the Federal Reserve Board approves an application by
Grantee under the BHCA to acquire the shares of Common Stock subject to the
Option, Grantee may not assign its rights under the Option except in (i) a
widely dispersed public distribution, (ii) a private placement in which no one
party acquires the right to purchase in excess of 2% of the voting shares of
Issuer, (iii) an assignment to a single party (e.g., a broker or investment
banker) for the purpose of conducting a widely dispersed public distribution on
Grantee's behalf, or (iv) any other manner approved by the Federal Reserve
Board.

         14. Each of Grantee and Issuer will use its best efforts to make all
filings with, and to obtain consents of, all third parties and governmental
authorities necessary to the consummation of the transactions contemplated by
this Agreement, including without limitation making application to list the
shares of Common Stock issuable hereunder on the American Stock Exchange or
Nasdaq on official notice of issuance and applying to the Federal Reserve Board
under the BHCA for approval to acquire the shares issuable hereunder, but
Grantee shall not be obligated to apply to state banking authorities for
approval to acquire the shares of Common Stock issuable hereunder until such
time, if ever, as it deems appropriate to do so.


                                      -10-
   219
         15. The parties hereto acknowledge that damages would be an inadequate
remedy for a breach of this Agreement by either party hereto and that the
obligations of the parties hereto shall be enforceable by either party hereto
through injunctive or other equitable relief.

         16. If any term, provision, covenant or restriction contained in this
Agreement is held by a court or a federal or state regulatory agency of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions and covenants and restrictions contained in this Agreement
shall remain in full force and effect, and shall in no way be affected, impaired
or invalidated. If for any reason such court or regulatory agency determines
that the Holder is not permitted to acquire, or Issuer is not permitted to
repurchase pursuant to Section 7, the full number of shares of Common Stock
provided in Section 1(a) hereof (as adjusted pursuant to Section 1(b) or 5
hereof), it is the express intention of Issuer to allow the Holder to acquire or
to require Issuer to repurchase such lesser number of shares as may be
permissible, without any amendment or modification hereof.

         17. All notices, requests, claims, demands and other communications
hereunder shall be deemed to have been duly given when delivered in person, by
cable, telegram, telecopy or telex, or by registered or certified mail (postage
prepaid, return receipt requested) at the respective addresses of the parties
set forth in the Merger Agreement.

         18. This Agreement shall be governed by and construed in accordance
with the laws of the State of Connecticut, regardless of the laws that might
otherwise govern under applicable principles of conflicts of laws thereof.

         19. This Agreement may be executed in two or more counterparts, each of
which shall be deemed to be an original, but all of which shall constitute one
and the same agreement.

         20. Except as otherwise expressly provided herein, each of the parties
hereto shall bear and pay all costs and expenses incurred by it or on its behalf
in connection with the transactions contemplated hereunder, including fees and
expenses of its own financial consultants, investment bankers, accountants and
counsel.

         21. Except as otherwise expressly provided herein or in the Merger
Agreement, this Agreement contains the entire agreement between the parties with
respect to the transactions contemplated hereunder and supersedes all prior
arrangements or understandings with respect thereof, written or oral. The terms
and conditions of this Agreement shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and permitted assigns.
Nothing in this Agreement, expressed or implied, is intended to confer upon any
party, other than the parties hereto, and their respective successors and
assigns, any rights, remedies, obligations or liabilities under or by reason of
this Agreement, except as expressly provided herein.

         22. Capitalized terms used in this Agreement and not defined herein
shall have the meanings assigned thereto in the Merger Agreement.


                                      -11-
   220
         IN WITNESS WHEREOF, each of the parties has caused this Agreement to be
executed on its behalf by its officers thereunto duly authorized, all as of the
date first above written.

                            Form of Letter Agreement

                                             July 24 1998

Westbank Corporation
225 Park Avenue
West Springfield, MA 01089-3326

Gentlemen:

         I have been advised that I might be considered to be an "affiliate" of
Westbank Corporation for purposes of generally accepted accounting principles as
such term relates to pooling of interests accounting treatment for certain
business combinations under generally accepted accounting principles and the
interpretations of the Securities and Exchange Commission (the "SEC") or its
staff, including, without limitation, Section 201.01 of the SEC's Codification
of Financial Reporting Policies and the SEC's Staff Accounting Bulletin No. 65.
Neither my entering into this letter agreement, nor anything contained herein,
shall be deemed an admission on my part that I am such an "affiliate".

         Westbank Corporation, a Massachusetts corporation ("Westbank"), and its
subsidiary Park West Bank and Trust Company, a Massachusetts chartered state
bank and trust company have entered into an Affiliation and Merger Agreement
with Cargill Bancorp, Inc., a Delaware corporation ("Cargill") and its
subsidiary Cargill Bank, a Connecticut chartered stock savings and loan
association dated on or about the date hereof (the "Merger Agreement"),
providing for among other things, the merger (the "Merger") of Cargill with and
into Westbank with Westbank being the surviving corporation in the Merger. Upon
consummation of the Merger, Shareholders of Cargill will receive shares of
common stock, par value $2.00 per share, in exchange for all of their shares of
common stock of Cargill. This agreement is hereinafter referred to as the
"Letter Agreement".

         I represent and warrant to, and agree with, Westbank as follows:

                  1. I have read this Letter Agreement and the Merger Agreement
and have discussed their requirements and other applicable limitations upon my
ability to sell, pledge, transfer or otherwise dispose of shares of Westbank
Common Stock, to the extent I felt necessary, with my counsel or counsel for
Westbank.

                  2. I hereby agree that (a) without the consent of Westbank if
prior to the Effective Date of the Merger, or (b) without the consent of
Westbank if subsequent to the Effective Date of the Merger, (i) I will not sell
or otherwise reduce my risk relative to any shares of Westbank Common Stock
during the period of thirty (30) days prior to the effective date of the Merger,
and (ii) I will not sell or otherwise reduce my risk relative to any shares of
Westbank
   223
Westbank Corporation
July 24, 1998

Common Stock until financial results covering at least thirty (30) days of
combined operations have been published following the effective date of the
Merger.

         I agree that, if I desire to dispose of any shares of Westbank Common
Stock owned by me after the date of this Letter Agreement and prior to the
release of financial results covering at least thirty (30) days of combined
operations have been published following the effective date of the Merger, I
will affirmatively inquire of Westbank through its counsel, Cranmore, FitzGerald
& Meaney, if prior to the effective date of the Merger, whether I may so dispose
of said shares of Westbank Common Stock, or counsel for Westbank following the
effective date of Merger whether I may so dispose of shares of Westbank Common
Stock, without violating the requirements of this Letter Agreement. I will
dispose of said shares only if such inquiry is answered in the affirmative by
the written response of said counsel.

         It is understood and agreed that this Letter Agreement shall terminate
and be of no further force and effect if the Merger Agreement is terminated. It
is also understood and agreed that this Letter Agreement shall terminate and be
of no further force and effect at such time as (i) financial results covering at
least thirty (30) days of combined operations following the effective date of
the Merger have been published, or (ii) delivery by the undersigned to Westbank
of a copy of a letter from the staff of the SEC, or an opinion of counsel in
form and substance reasonably satisfactory to Westbank, or other evidence
reasonably satisfactory to Westbank, to the effect that a transfer of my shares
of Westbank Common Stock will not violate or any of the rules and regulations of
the SEC.

         This Letter Agreement shall be binding on my heirs, legal
representatives and successors.

                                             Very truly yours,
   224
                                                                     Exhibit E-1

Members of the Board:

         You have requested an update of our opinion as to the fairness, from a
financial point of view, of the terms of an Agreement and Plan of Merger dated
July 14, 1998 (the "Merger Agreement"), by and among Westbank Corporation.
("Westbank") and its principal subsidiary Parkwest Bank and Trust Company, and
Cargill Bancorp, Inc. ("Cargill") and its principal subsidiary Cargill Bank, to
the holders of Cargill Common Stock, $.01 par value, ("Cargill Common Stock").

         Pursuant to the terms of the Merger Agreement, Cargill will be acquired
by Westbank through the merger of Cargill with and into Westbank (the "Merger").
The Merger Agreement provides that each outstanding share of Cargill Common
Stock shall be converted automatically into and be exchangeable for shares of
Westbank in accordance with the Exchange Ratio (rounded to the nearest ten
thousandth of a share). The Exchange Ratio shall be (i) if the Westbank Market
Value is greater than or equal to $13.07, then 1.3008 fully paid and
nonassessable shares of Westbank Common Stock; (ii) if the Westbank Market Value
is less than $13.07 but greater than or equal to $12.00, then the number of
fully paid and nonassessable shares of Westbank Common Stock obtained by
dividing (A)$17.00 per share by (B) the Westbank Market Value; and (iii) if
Westbank Market Value is less than $12.00, then 1.4167 fully paid and
nonassessable shares of Westbank Common Stock , subject to adjustment as
provided in Section 11.1.7 of the Agreement.

         In connection with executing the Agreement, Cargill entered into an
Option Agreement dated July 14, 1998 ("the Option Agreement"), pursuant to which
Cargill has granted Westbank an option to acquire up to 84,804 fully paid and
nonassessable shares of Cargill Common Stock at a price of $12.00 per share;
provided further that in no event shall the number of shares of Common Stock for
which this Option is exercisable exceed 19.9% of the Cargill's issued and
outstanding shares of common stock after giving effect to any shares subject to
or issued pursuant to the Option. Westbank may exercise this Option upon the
occurrence of certain events specified in the Option Agreement.

         Ostrowski & Company, Inc., as part of its bank and thrift advisory
business, is regularly engaged in the valuation of financial institutions and
their securities in connection with mergers and acquisitions and other corporate
purposes. We are familiar with Cargill and have received and will receive fees
from Cargill for issuing an opinion as to the fairness, from a financial point
of view, of the terms of the proposed transaction as set forth in the Merger
Agreement.

         In connection with providing this update of our opinion, we have
examined and relied upon, among other things: the Merger Agreement; the Westbank
Corporation Registration Statement on Form S-4 filed on September 30, 1998 with
the Securities and Exchange Commission and the draft thereto of Amendment Number
1 dated October 28, 1998; annual reports to shareholders, proxy statements and
related audited financial statements for Cargill for each of the three fiscal
years ended September 30, 1995, 1996 and 1997; certain unaudited interim
financial reports for Cargill for the quarters ended December 31, 1997, March
31, 1998 and June 30, 1998 and for the fiscal year ended September 30, 1998,
certain other financial information for Cargill, including proforma financial
statements and management's estimates relating to, among other things, earnings,
asset quality, loan delinquencies and capital ; annual reports to shareholders,
proxy statements and related audited financial statements for Westbank for each
of the three fiscal years ended December 31, 1995, 1996 and 1997; certain
unaudited interim financial reports for Westbank for the quarters ended March
31, 1998, June 30, 1998 and September 30, 1998 and certain other financial
information for Westbank, including proforma financial statements and
management's estimates relating to, among other things, earnings, asset quality,
loan delinquencies and capital. We have conducted discussions with executive
management of Cargill and Westbank concerning historical financial performance
and condition, market area economic conditions, future business prospects and
financial forecasts. We have reviewed comparable financial, operating and market
data for the banking industry and selected peer groups; compared the terms of
the Merger Agreement with other bank and thrift merger and acquisition
transactions; and have considered such additional financial and other
information deemed relevant.

         In preparing our opinion, we have relied upon the accuracy,
completeness and fair presentation of all information supplied or otherwise made
available to us by, or on behalf of, Cargill and Westbank. We have not
independently verified such information or undertaken an independent evaluation
or appraisal of the assets or liabilities of Cargill or Westbank, nor have we
been furnished any such evaluations or appraisals. With respect to forecasts of
expected future financial performance, we have been advised that they reflect
the best currently available estimates and judgement of the executive
management. This opinion is necessarily based upon the information available to
us and the market, economic and other conditions, as they exist and can be
evaluated, as of the date of this letter.

         This opinion is directed solely to the fairness, from a financial point
of view, of the terms of the Merger Agreement to Cargill Shareholders and does
not constitute a recommendation to any Cargill Shareholder as to how such
Cargill Shareholder should vote with respect to the Merger Agreement.

         In reliance upon and subject to the foregoing, it is our opinion that
as of the date hereof, the terms of the Merger Agreement are fair, from a
financial point of view, to Cargill Shareholders.

The Board of Directors
Westbank Corporation
225 Park Avenue
West Springfield, MA 01089

Members of the Board:

         You have requested our opinion as to the fairness, from a financial
point of view, to the shareholders of Westbank Corporation ("Westbank") of the
Exchange Ratio (as defined below) in the proposed merger (the "Merger") of
Cargill Bancorp, Inc. ("Cargill"), with and into Westbank, pursuant to the
Affiliation and Merger Agreement (the "Merger Agreement") dated July 15, 1998.

         Under the terms of, and subject to certain conditions as defined in the
Merger Agreement, each issued and outstanding share of common stock, $0.01 par
value, of Cargill, except for any dissenting shares and except for any shares
held by Westbank will be entitled to receive Merger Consideration payable in
shares of common stock, $2.00 par value per share, of Westbank Corporation
("Westbank Common Stock"). The Merger Consideration will be based on the average
of the closing prices per share of Westbank Common Stock during the twenty
consecutive trading day period ending on the fifth trading day immediately
preceding the Determination Date (the "Westbank Market Value"). The exchange
ratio will be equal to 1.3008 shares of Westbank Common Stock, subject to the
adjustments described below (the "Exchange Ratio").

         If the Westbank Market Value is greater than $13.07, then Cargill
shareholders shall receive an Exchange Ratio of 1.3008 shares of Westbank Common
Stock for each share of Cargill stock. If the Westbank Market Value is less than
$13.07 but greater than or equal to $12.00, then Cargill shareholders shall
receive an Exchange Ratio equal to $17.00 divided by the Westbank Market Value.
If the Westbank Market Value is less than $12.00, then Cargill shall have the
right to terminate the Merger, provided however, that Westbank shall have the
option to increase the Exchange Ratio above 1.4167 as provided in the Merger
Agreement.

         Northeast Capital & Advisory, Inc., as part of its investment banking
business, is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements and valuations for estate, corporate and
other purposes. We are familiar with Westbank, having acted as its financial
advisor in connection with, and having participated in certain areas of the
negotiations leading to, the Merger Agreement. We also have provided investment
banking services to Westbank since 1989.

                                                                        Page - 2


         In connection with this opinion, we have reviewed, among other things,
Registration Statement/Proxy, the Merger Agreement; the Annual Reports of
Cargill for the three years ended September 30, 1997; the Annual Report to
Shareholders on Form 10-K of Westbank for the year ending December 31, 1997;
certain Quarterly Reports of Cargill and Westbank; certain unaudited interim
reports and certain press releases to the respective shareholders of Westbank
and Cargill; and financial information concerning the business and operations of
Westbank and Cargill furnished to us by their respective managements. We also
have conducted discussions with members of the senior managements of Westbank
and Cargill regarding the past and current business operations, regulatory
relationships, financial condition and future prospects of their respective
companies. In addition, we have reviewed the reported price and trading activity
of Cargill's and Westbank's common stock; compared certain financial information
for Westbank and Cargill with certain financial and stock market information for
certain other companies, the securities of which are publicly traded; reviewed
the financial terms of certain recent business combinations in the commercial
banking environment in particular; and performed such other studies and analyses
as we considered appropriate.

         In conducting our review and arriving at our opinion, we relied upon
and assumed the accuracy and completeness of all of the financial and other
information provided to us or publicly available and we have not attempted
independently to verify such information. We have generally relied upon the
management of Westbank and Cargill as to the reasonableness and achievability of
the financial and operating forecasts and projections (and the assumptions and
bases therefor) provided to us, and we have generally assumed that such
forecasts and projections reflect the best currently available estimates and
judgments of such managements and that such forecasts and projections will
generally be realized in the amounts and in the time periods currently estimated
by such managements. We have also assumed that the aggregate allowance for loan
losses for Westbank and Cargill is adequate to cover such losses. We have not
made nor obtained any evaluations or appraisals of the property of Westbank and
Cargill. We have, however, independently examined certain individual loan credit
files of Cargill and independently produced projections and operating forecasts
to assure ourselves that the assumptions generated by management of Westbank and
Cargill in their projections and forecasts do not materially and adversely alter
the adequacy of the financial consideration being exchanged by Westbank
shareholders, from a financial point of view. Finally, you have informed us
that, while not a condition to the transaction, the Merger is intended to be
accounted for as a pooling of interests transaction under generally accepted
accounting principles.

         In conducting our analysis and arriving at our opinion as expressed
herein, we have considered such financial and other factors as we have deemed
appropriate in the circumstances. We have also taken into account our assessment
of general economic, market and financial conditions, our experience in other
transactions, and our knowledge of the banking industry in general. In rendering
our opinion, we have assumed that in the course of obtaining the necessary
regulatory approvals for the Merger, no conditions will be imposed that will
have a material adverse effect on the contemplated benefits of the Merger to
Westbank. Our opinion is based upon information, conditions and projections as
they exist and can be evaluated on the date hereof.

         Based upon and subject to the foregoing, it is our opinion that the
Exchange Ratio of the Merger as provided and described in the Merger Agreement
is fair, from a financial point of view, to Westbank and its shareholders.


                                        Very truly yours,

                        DELAWARE GENERAL CORPORATION LAW
                          SECTION 262. APPRAISAL RIGHTS.

         (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to the provisions of
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with the provisions of subsection (d) of this Section and
who has neither voted in favor of the merger or consolidation nor consented
thereto in writing pursuant to Section 228 of this Chapter shall be entitled to
an appraisal by the Court of Chancery of the fair value or his shares of stock
under the circumstances described in subsections (b) and (c) of this Section. As
used in this Section, the word "stockholder" means a holder of record of stock
in a stock corporation and also a member of record of a non-stock corporation;
the words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a non-stock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.

         (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to Sections 251, 252, 254, 257, 258, or 263 of this Chapter;

         (1) provided, however, that no appraisal rights under this Section
shall be available for the shares of any class or series of stock, which stock,
or depository receipts in respect thereof, at the record date fixed to determine
the stockholders entitled to receive notice of and to vote at the meeting of
stockholders to act upon the agreement of merger or consolidation, were either
(i) listed on a national securities exchange or (ii) held of record by more than
2,000 holders; and further provided that no appraisal rights shall be available
for any shares of stock of the constituent corporation surviving a merger if the
merger did not require for its approval the vote of the holders of the surviving
corporation as provided in subsection (f) of Section 251 of this Chapter.

         (2) Notwithstanding the provisions of subsection (b) (1) of this
Section, appraisal rights under this Section shall be available for the shares
of any class or series of stock of a constituent corporation if the holders
thereof are required by the terms of an agreement of merger or consolidation
pursuant to Sections 251, 252, 254, 257, 258, 263 and 264 of this Chapter to
accept for such stock anything except (i) shares of stock of the corporation
surviving or resulting from such merger or consolidation, or depository receipts
in respect thereof; (ii) shares of stock of any other corporation, or depository
receipts in respect thereof, which shares of stock or depository receipts at the
effective date of the merger or consolidation will be either listed on a
national securities exchange or held of record by more than 2,000 holders; (iii)
cash in lieu of fractional shares or fractional depository receipts described in
the foregoing clauses (i) and (ii); or (iv) any combination of the shares of
stock, depository receipts and cash in lieu of fractional shares or fractional
depository receipts described in the foregoing clauses (i), (ii) and (iii) of
this subsection.
   235
         (3) In the event all of the stock of a subsidiary Delaware corporation
party to a merger effected under Section 253 of this Chapter is not owned by
the parent corporation immediately prior to the merger, appraisal rights shall
be available for the shares of the subsidiary Delaware corporation.

         (c) Any corporation may provide in its certificate of incorporation
that appraisal rights under this Section shall be available for the shares of
any class or series of its stock as a result of an amendment to its certificate
of incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this Section, including those set forth in subsection (d) and
(e), shall apply as nearly as is practicable.

         (d) Appraisal rights shall be perfected as follows:

         (1) If a proposed merger or consolidation for which appraisal rights
are provided under this Section is to be submitted for approval at a meeting of
stockholders, the corporation, not less than 20 days prior to the meeting, shall
notify each of its stockholders who was such on the record date for such meeting
with respect to shares for which appraisal rights are available pursuant to
subsections (b) and (c) hereof that appraisal rights are available for any or
all of the shares of the constituent corporations, and shall include in such
notice a copy of this Section. Each stockholder electing to demand the appraisal
of his shares shall deliver to the corporation, before the taking of the vote on
the merger or consolidation, a written demand for appraisal of his shares. Such
demand will be sufficient if it reasonably informs the corporation of the
identity of the stockholder and that the stockholder intends thereby to demand
the appraisal of his shares. A proxy or vote against the merger or consolidation
shall not constitute such a demand. A stockholder electing to take such action
must do so by a separate written demand as herein provided. Within 10 days after
the effective date of such merger or consolidation, the surviving or resulting
corporation shall notify each stockholder of each constituent corporation who
has complied with the provisions of this subsection and has not voted in favor
of or consented to the merger or consolidation of the date that the merger or
consolidation has become effective; or

         (2) If the merger or consolidation was approved pursuant to Section 228
or Section 253 of this Chapter, the surviving or resulting corporation, either
before the effective date of the merger or consolidation or within 10 days
thereafter, shall notify each of the stockholders entitled to appraisal rights
or the effective date of the merger or consolidation and that appraisal rights
are available for any or all of the shares of the constituent corporation, and
shall include in such notice a copy of this Section. The notice shall be sent by
certified or registered mail, return receipt requested, addressed to the
stockholder at his address as it appears on the records of the corporation. Any
stockholder entitled to appraisal rights may, within 20 days after the date of
mailing of notice, demand in writing from the surviving or resulting corporation
the appraisal of his shares. Such demand will be sufficient if it reasonably
informs the corporation of the identity of the stockholder and that the
stockholder intends thereby to demand the appraisal of his shares.


                                      -2-
   236
         (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with the provisions of subsections (a) and (d) hereof and who is
otherwise entitled to appraisal rights, may file a petition in the Court of
Chancery demanding a determination of the value of the stock of all such
stockholders. Notwithstanding the foregoing, at any time within 60 days after
the effective date of the merger or consolidation, any stockholder shall have
the right to withdraw his demand for appraisal and to accept the terms offered
upon the merger or consolidation. Within 120 days after the effective date or
the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10 days
after his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.

         (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving, or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by one or more publications at
least one week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

         (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with the provisions of this Section and who have
become entitled to appraisal rights. The Court may require the stockholders who
have demanded an appraisal for their shares and who hold stock represented by
certificates to submit their certificates of stock to the Register in Chancery
for notation thereon of the pendency of the appraisal proceedings and if any
stockholder fails to comply with such direction, the Court may dismiss the
proceedings as to such stockholder.


                                      -3-
   237
         (h) After determining the stockholders entitled to an appraisal, the
Court shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determinating, the fair
rate of interest, the Court may consider all relevant factors, including the
rate of interest which the surviving or resulting corporation would have had to
pay to borrow money during the pendency of the proceeding. Upon application by
the surviving or resulting corporation or by any stockholder entitled to
participate in the appraisal proceeding, the Court may, in its discretion,
permit discovery or other pretrial proceedings and may proceed to trial upon the
appraisal prior to the final determination of the stockholder entitled to an
appraisal. Any stockholder whose name appears on the list filed by the surviving
or resulting corporation pursuant to subsection (f) of this Section and who has
submitted his certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that he is not entitled to appraisal rights under this Section.

         (i) The Court shall direct the payment of the fair value of the shares,
together with interest. if any, by the surviving or resulting, corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be made to each such stockholder, in the case of
holders of uncertified stock forthwith, and in the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any other state.

         (j) The costs of the proceeding may be determined by the Court and
taxed upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorneys' fees and the
fees and expenses of experts, to be charged pro rata against the value of all of
the shares entitled to an appraisal.

         (k) From and after the effective date of the merger or consolidation,
no stockholder who has demanded his appraisal rights as provided in subsection
(d) of this Section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this Section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this Section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.


                                      -4-
   238
         (1) The shares of the surviving or resulting corporation into which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

           Section 67 of Chapter 156B of the Massachusetts General Laws, the
Massachusetts Business Corporation Law (the "MBCL") provides, in effect, that a
corporation may indemnify any person made a party to any action by reason of the
fact that he is or was a director, officer, employee or agent of the corporation
against, in the case of a nonderivative action, judgments, fines, amounts paid
in settlement and reasonable expenses (including attorney's fees) incurred by
him as a result of such action, and in the case of a derivative action, against
expenses (including attorney's fees), if in either type of action he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation. This indemnification does not apply, in a
derivative action, to matters as to which it is adjudged that the director,
officer, employee or agent is liable to the corporation, unless upon court order
it is determined that, despite such adjudication of liability, but in view of
all the circumstances of the case, he is fairly and reasonable entitled to
indemnity for expenses, and, in a nonderivative action, to any criminal
proceeding in which such person had reasonable cause to believe his conduct was
unlawful.

         Article V, Section 9 of Westbank's Bylaws provides that Westbank shall
indemnify each person who is or was an officer, director, employee or agent of
Westbank against all liabilities and expenses reasonably incurred by such
indemnitee in connection with such proceeding, provided that such indemnitee
shall undertake to repay such payment if he shall be adjudicated to be not
entitled to indemnification.

ITEM 22.  UNDERTAKINGS

        (a) The undersigned Registrant hereby undertakes as follows:

(1)      To file, during any period in which offers or sales are being made, a
         post-effective amendment to this registration statement:

            (i)   To include any prospectus required by Section 10(a)(3) of the
                  Securities Act of 1933;

            (ii)  To reflect in the prospectus any facts or events arising after
                  the effective date of the registration statement (or the most
                  recent post-effective amendment thereof) which, individually
                  or in the aggregate, represent a fundamental change in the
                  information set forth in the registration statement; and

            (iii) To include any material information with respect to the plan
                  of distribution not previously disclosed in the registration
                  statement or any material change to such information in the
                  registration statement.

                  Provided, however, that paragraphs (a) (1) (i) and (a) (1)
(ii) do not apply if the registration statement is on Form S-3 or Form S-8, and
the information required to be included in post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the registration statement.

(2)      That, for purposes of determining any liability under the Securities
         Act of 1933, each filing of the registrant's annual report pursuant to
         section 13(a) or section 15(d) of the Securities Exchange Act of 1934
         (and, where applicable, each filing of an employee benefit plan's
         annual report pursuant to section 15(d) of the Securities Exchange Act
         of 1934) that is incorporated by reference in the registration
         statement shall be deemed to be a new registration statement relating
         to the securities offered therein, and the offering of such securities
         at that time shall be deemed to be the initial bona fide offering
         thereof.

(3)      That prior to any public reoffering of the securities registered
         hereunder through use of a prospectus which is a part of this
         registration statement, by any person or party who is deemed to be an
         underwriter within the meaning of Rule 145(c), the issuer undertakes
         that such reoffering prospectus will contain the information called for
         by the applicable registration form which respect to reofferings by
         persons who may be deemed underwriters, in addition to the information
         called for by the other Items of the applicable form.

(4)      That every prospectus (i) that is filed pursuant to paragraph (3)
         immediately preceding, or (ii) that purports to meet the requirements
         of Section 10(a)(3) of the Act and is used in connection with an
         offering of securities subject to Rule 415, will be filed as a part of
         an amendment to the registration statement and will not be used until
         such amendment is effective, and that, for purposes of determining any
         liability under the Securities Act of 1933, each such post-effective
         amendment shall be deemed to be a new registration statement
   242
         relating to the securities offered therein, and the offering of such
         securities at that time shall be deemed to be the initial bona fide
         offering thereof.

(5)      That, for the purpose of determining any liability under the Securities
         Act of 1933, each post-effective amendment that contains a form of
         prospectus shall be deemed to be a new registration statement relating
         to the securities offered therein, and the offering of such securities
         at that time shall be deemed to be the initial bona fide offering
         thereof.

(6)      To remove from registration by means of a post-effective amendment any
         of the securities being registered which remain unsold at the
         termination of the offering.

(7)      Insofar as indemnification for liabilities arising under the Securities
         Act of 1933 may be permitted to directors, officers and controlling
         persons of the registrant pursuant to the foregoing provisions, or
         otherwise, the registrant has been advised that in the opinion of the
         Securities and Exchange Commission such indemnification is against
         public policy as expressed in the Act and is, therefore, unenforceable.
         In the event that a claim for indemnification against such liabilities
         (other than the payment by the registrant of expenses incurred or paid
         by a director, officer or controlling person of the registrant in the
         successful defense of any action, suit or proceeding) is asserted by
         such director, officer or controlling person in connection with the
         securities being registered, the registrant will, unless in the opinion
         of its counsel the matter has been settled by controlling precedent,
         submit to a court of appropriate jurisdiction the questions whether
         such indemnification by it is against public policy as expressed in the
         Act and will be governed by the final adjudication of such issue.

         (b) The undersigned registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Items 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

         (c) The undersigned registrant hereby undertakes to supply by means of
a post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
   243

      Pursuant to the requirements of the Securities Exchange Act of 1933, the
Registrant has duly caused this Amendment to the Registration Statement to be
