                                       OF
                           HUDSON RIVER BANCORP, INC.
                                       FOR
                   SHARES OF TRUSTCO BANK CORP NY COMMON STOCK
                                       and
                        $10.20 Net to the Seller in Cash
                                     MADE BY
                              TRUSTCO BANK CORP NY

            TrustCo is offering, upon the terms and subject to the conditions
set forth herein and in the related letter of transmittal, to acquire each share
of Hudson River Bancorp, Inc. common stock held by you for a combination of
shares of TrustCo common stock and cash totaling $17.00. The stock component of
the exchange consideration will consist of shares of TrustCo stock that have an
aggregate value of $6.80, and the cash component will be $10.20. The purpose of
this offer is for TrustCo to acquire control of, and ultimately the entire
common equity interest in, Hudson. TrustCo intends, promptly after consummation
of this offer, to have Hudson consummate a merger with a wholly owned subsidiary
of TrustCo in which each outstanding share of common stock of Hudson, (except
for treasury shares and shares of Hudson stock beneficially owned directly or
indirectly by TrustCo for its own account, including those acquired pursuant to
this offer) would be converted into a number of shares of TrustCo common stock
that have an aggregate value of $6.80 plus cash in the amount of $10.20 for each
share of Hudson stock held by you.

            We expect that if you realize a gain on the exchange, you will be
taxed on such gain up to the amount of the $10.20 per share cash component of
the consideration that you receive in exchange for your shares of Hudson common
stock but will not recognize any loss realized. In addition, we expect that you
will be taxed on any gain realized on the cash received in lieu of fractional
shares of TrustCo common stock. See "The Offer--Material Federal Income Tax
Consequences."


            Our obligation to exchange TrustCo common stock for Hudson common
stock is subject to the conditions listed under "THE EXCHANGE OFFER--Certain
Conditions of the Exchange Offer."


            TrustCo has also offered to acquire control of, and ultimately the
entire common equity interest in, Cohoes Bancorp, Inc., by offering to exchange
$18.00 in TrustCo stock and cash for each outstanding share of Cohoes common
stock. The TrustCo common stock is listed on the Nasdaq National Market under
the symbol "TRST," the Hudson common stock is listed on the Nasdaq under the
symbol "HRBT," and the Cohoes common stock is listed on the Nasdaq under the
symbol "COHB."

              QUESTIONS AND ANSWERS ABOUT THE PROPOSED ACQUISITION

Q:          WHAT IS TRUSTCO PROPOSING?


A:          We are proposing to acquire control of, and ultimately the entire
            common equity interest in, Hudson by first offering to exchange all
            outstanding shares of Hudson stock for shares of TrustCo stock and
            cash. Second, we intend, promptly after completion of the offer, to
            merge Hudson with a wholly owned subsidiary of TrustCo. As a result
            of the TrustCo-Hudson merger, each share of Hudson stock which has
            not been exchanged or accepted for exchange would be converted into
            the same number of shares of TrustCo stock and the same amount of
            cash as is paid in the offer.


Q:          WHAT WILL I RECEIVE IN EXCHANGE FOR MY SHARES?


A:          For each share of Hudson stock validly tendered and not properly
            withdrawn by you, you will receive a combination of TrustCo stock
            and cash with an aggregate value of $17.00. The stock component of
            the exchange consideration will consist of a number of shares of
            TrustCo stock having an aggregate value of $6.80 (such number of
            shares to be determined by the average closing price of the TrustCo
            stock on the Nasdaq over a 20-day period ending 5 days before the
            closing on our offer), and the cash component will be $10.20 net.
            You will not receive any fractional shares of TrustCo stock.
            Instead, you will receive additional cash in an amount equal to the
            average closing price of one share of TrustCo stock on the Nasdaq
            over such 20-day period multiplied by the fractional share of
            TrustCo stock you are entitled to receive.

Q:          What is the status of Hudson's proposed merger with Cohoes?

A:          On August 18, 2000, Cohoes announced that its shareholders failed to
            approve the proposed merger between Cohoes and Hudson; and on
            September 28, Cohoes and Hudson announced that they had terminated
            their merger agreement.

Q:          Why should I participate in your offer?

            A: The TrustCo offer is $17.00 in TrustCo stock and cash for each
            share of Hudson stock. We believe that our proposed offer represents
            an opportunity to enhance value for Hudson stockholders by
            providing, among other things:


            o           a premium over the price levels at which we believe
                        Hudson stock would be trading in the absence of our
                        offer;

            o           better long-term growth prospects;

            o           improved cash dividends; and

            o           TrustCo stock, a stock which has exhibited superior
                        performance when compared in most respects to Hudson
                        stock (for example, TrustCo has realized a 23% average
                        annual total return for the three year period ended
                        December 31, 1999).

Q:          HOW DO I PARTICIPATE IN YOUR OFFER?

A:          To tender your shares of Hudson stock, you should do the following.

            o           If you hold shares in your own name, complete and sign
                        the enclosed letter of transmittal and return it with
                        your share certificate to ChaseMellon Shareholder
                        Services, the exchange agent for the offer, at the
                        address specified on the back cover page of this
                        Prospectus before the expiration date of the offer.


                                       2
<PAGE>

            o           If you hold your shares in "street name" through a
                        broker, instruct your broker to tender your shares
                        before the expiration date of the offer.

Q:          WILL I CONTINUE TO RECEIVE DIVIDENDS AND HAVE VOTING RIGHTS WITH
            RESPECT TO HUDSON SHARES THAT I TENDER TO YOU?

A:          Yes. Until we accept your shares of Hudson stock for exchange at the
            completion of our offer, you will be entitled to receive any
            dividends paid on your tendered shares of Hudson stock and you will
            continue to have the right to vote your tendered shares. Once we
            complete our offer and exchange all shares of Hudson stock tendered
            by you in the offer and not withdrawn, you will own TrustCo stock
            and will have all dividend and voting rights of a TrustCo
            stockholder.

Q:          WHEN AND HOW CAN I WITHDRAW TENDERED SHARES?

A:          Shares of Hudson stock tendered in the offer may be withdrawn by you
            at any time after _________, 2000 and prior to the exchange of your
            shares for TrustCo stock. Your withdrawal will only be effective if
            the exchange agent receives a written notice of withdrawal at the
            address on the back cover of this Prospectus, or by facsimile at
            (201) 296-4293. The written notice must contain your name, address,
            social security number, number of shares of Hudson stock to be
            withdrawn, the certificate number or numbers for such shares and the
            name of the registered holder of the shares, if different from the
            person who tendered the shares. All signatures on the notice of
            withdrawal must be guaranteed by a financial institution in
            accordance with the procedures set forth in this Prospectus under
            "THE EXCHANGE OFFER--Withdrawal Rights."

Q:          HOW WOULD YOU GO ABOUT COMPLETING YOUR PROPOSED ACQUISITION?

A:          We have taken several steps in furtherance of our offer, including
            the following.


            o           We have commenced our offer by mailing this Prospectus
                        and the related letter of transmittal to Hudson
                        stockholders.

            o           We expect to file within the next several days an
                        application with the Federal Reserve Board to obtain the
                        regulatory approvals necessary to complete the offer and
                        a TrustCo-Hudson merger.

            o           If required by the rules of the Nasdaq Stock Market due
                        to the number of shares of TrustCo stock to be issued in
                        our proposed acquisition of Cohoes, we will, we will
                        file with the SEC proxy materials to be used for
                        soliciting the approval by our stockholders of that
                        issuance of our shares .


Q:          HOW LONG WILL IT TAKE TO COMPLETE YOUR PROPOSED OFFER?


A:          We believe that the offer could close in the latter part of the
            first quarter of 2001. This schedule assumes that the Hudson board
            of directors promptly cooperates with us. However, the Hudson board
            may try to delay our offer. By tendering your shares, you will be
            sending a message to Hudson management and the Hudson board that you
            want Hudson to participate in a combination with us.


Q:          WHAT ARE THE CONDITIONS TO YOUR OFFER?

A:          Our offer is subject to several conditions, including:

            o           tender of enough shares of Hudson stock so that, after
                        completion of our offer, we own at least a majority of
                        the outstanding shares of Hudson stock (on a fully
                        diluted basis);


            o           the valid termination of the stock option agreement
                        between Hudson and Cohoes ;

                        TrustCo and Hudson and the approval thereof by Hudson's
                        board of directors and its shareholders;


            o           the receipt of all required regulatory approvals;


            o           the receipt of an opinion that a TrustCo-Hudson merger
                        would qualify as a tax-free transaction;

            o           the effectiveness of the Registration Statement of which

                        anti-takeover impediments found in Hudson's Certificate
                        of Incorporation do not apply to or otherwise restrict
                        our offer and the proposed TrustCo-Hudson merger; and

                        the approval by our stockholders of the issuance of
                        TrustCo stock in our offer for Hudson.

            These conditions and other conditions to our offer are discussed in
            this Prospectus under "THE EXCHANGE OFFER--Certain Conditions of the
            Exchange Offer." The conditions must be satisfied or waived on or

            component of the consideration that you receive in exchange for your
            shares of Hudson common stock but will not recognize any loss
            realized. In addition, we expect that you will be taxed on any gain
            realized on the cash received in lieu of fractional shares of
            TrustCo common stock.

Prospectus to the date that shares of Hudson stock are accepted for exchange
pursuant to our offer (or the date that our offer is terminated) shall also be
deemed to be incorporated herein by reference.

            DOCUMENTS INCORPORATED BY REFERENCE ARE AVAILABLE FROM US WITHOUT
CHARGE UPON REQUEST TO WILLIAM F. TERRY, CORPORATE SECRETARY, TRUSTCO BANK CORP
NY, 320 STATE STREET, SCHENECTADY, NEW YORK 12305, (518) 377-3311. IN ORDER TO
ENSURE TIMELY DELIVERY, ANY REQUEST SHOULD BE SUBMITTED NO LATER THAN

            Please note that, although TrustCo is incorporating by reference
certain financial statements of both Cohoes and Hudson, TrustCo is not
incorporating by reference the audit report on Hudson's financial statements.
TrustCo has used its best efforts to obtain Hudson's permission and cooperation
for the incorporation by reference of Hudson's financial statements and to
obtain the consent of Hudson's auditors for the inclusion of its report on the
financial statements. TrustCo has not, however, obtained such permission or
consent from Hudson or its auditors. Although an audit report was issued on both
Cohoes' and Hudson's annual financial statements which have been incorporated by
reference and is included in Cohoes' and Hudson's respective filings, Hudson's
auditor has not consented to the use of its report in this Registration
Statement. As a general matter, an auditor will not consent to the use in a
registration statement of its report with respect to a company if the auditor
has not reviewed the registration statement and performed certain accounting
procedures with respect to the company to determine whether the information
contained in the audit report remains true. The implication of not obtaining the
consent of Hudson's auditors is that Hudson's auditors will not have performed
procedures to ensure that no facts or changed circumstances were brought to the
attention of the auditors that would render the audit report inaccurate as of
the date it was rendered.

            This Prospectus contains certain forward-looking statements
concerning the financial condition, results of operations and business of
TrustCo following the consummation of its proposed acquisition of Hudson and
Cohoes, the anticipated financial and other benefits of such proposed
acquisitions and the plans and objectives of TrustCo's management following such
proposed acquisitions, including, without limitation, statements relating to the
cost savings expected to result from the proposed acquisitions, anticipated
results of operations of the combined company following the proposed
acquisitions and projected earnings per share of the combined company following
the proposed acquisitions. Generally, the words "will," "may," "should,"
"continue," "believes," "expects," "intends," "anticipates" or similar
expressions identify forward-looking statements. These forward-looking
statements involve certain risks and uncertainties. Factors that could cause
actual results to differ materially from those contemplated by the
forward-looking statements include, among others, the following factors: (i)
cost savings expected to result from the proposed acquisitions may not be fully
realized or realized within the expected time frame; (ii) operating results
following the proposed acquisitions may be lower than expected; (iii)
competitive pressure among financial services companies may increase
significantly; (iv) costs or difficulties related to the integration of the
businesses of TrustCo, Hudson and/or Cohoes may be greater than expected; (v)
adverse changes in the interest rate environment may reduce interest margins or
adversely affect asset values of the combined company; (vi) general economic
conditions, whether nationally or in the market areas in which TrustCo, Hudson
and Cohoes conduct business, may be less favorable than expected; (vii)
legislation or regulatory changes may adversely affect the businesses in which
TrustCo, Hudson and Cohoes are engaged; or (viii) adverse changes may occur in
the securities markets.

THE TRUSTCO EXCHANGE OFFER (PAGE 32)


            We are proposing a business combination of TrustCo and Hudson. For
each share of Hudson stock tendered and not withdrawn by you, we are offering to
exchange a combination of shares of TrustCo common stock and cash totaling
$17.00. More specifically, you would receive, for each of your Hudson shares,
TrustCo common stock having a market value of $6.80 (the number of shares to be
determined by the average closing price of TrustCo stock on the Nasdaq over a
20-day period ending 5 days before the closing on our offer) and $10.20 net in
cash. We intend, promptly after completion of the offer, to merge Hudson with a
wholly owned subsidiary of TrustCo. Each share of Hudson stock that has not been
exchanged or accepted for exchange in the offer would be converted into the same
number of shares of TrustCo stock as is paid in the offer.

REASONS FOR THE TRUSTCO EXCHANGE OFFER (PAGE 30)

            We believe that our acquisition of Hudson represents an opportunity
to enhance value for both Hudson and TrustCo stockholders. Among the benefits
that we believe Hudson stockholders would obtain from the combination of TrustCo
and Hudson are the following:

            o           PREMIUM TO CURRENT VALUE. Our offer represents a premium
                        over the market price of Hudson common. The following
                        table shows the amount of the premium our offer would
                        have represented over the closing price of Hudson common
                        on June 23, 2000 (the last trading day prior to our
                        announcement of our initial offer for Hudson), August
                        18, 2000 (the date Cohoes announced its shareholders had
                        failed to approve the Hudson-Cohoes merger) and October
                        ___, 2000 (the last trading day prior to the date of
                        this Prospectus).

            o           BETTER LONG-TERM GROWTH PROSPECTS. We believe that a
                        combination of TrustCo and Hudson has better long-term
                        growth prospects than Hudson individually, potentially
                        resulting in increased shareholder value over the
                        long-term.

            o           IMPROVED CASH DIVIDENDS. We anticipate that Hudson
                        shareholders' pro forma dividends will exceed the Hudson
                        current annual dividend rate. The following table shows
                        the pro forma dividend that we would anticipate paying
                        to Hudson shareholders and the amount of the increase in
                        that dividend over Hudson's current annual dividend rate
                        assuming an exchange ratio based upon the closing price
                        of TrustCo common on June 23, 2000, August 18, 2000 and
                        October ___, 2000. TrustCo's current annualized dividend
                        is $0.60 per share, and Hudson's current annualized
                        dividend is $0.20 per share. Because the actual number
                        of shares of TrustCo common stock that Hudson's
                        stockholders will receive is not yet fixed, the
                        estimated amount of cash dividends Hudson's stockholders
                        will receive will fluctuate with the value of TrustCo
                        common stock.

         October ___, 2000

</TABLE>

            o           SUPERIOR PERFORMANCE. Based on past performance of
                        TrustCo stock (for example, TrustCo has realized more
                        than a 23% average annual total return for each of the
                        three-year, five-year and seven-year periods ended
                        December 31, 1999), we believe that Hudson stockholders
                        will realize superior performance over Hudson's common
                        stock. It should be noted, however, that each specific
                        aspect of the performance of TrustCo's common stock may
                        not, in all cases, be superior to that of Hudson's
                        common stock.


COMPARATIVE MARKET PRICE INFORMATION

            TrustCo, Hudson and Cohoes common stock trade on the Nasdaq under
the symbols "TRST", "HRBT" and "COHB", respectively.


            The following table lists the closing prices on the Nasdaq of the
stock of TrustCo and Hudson, the value of the TrustCo offer per share of Hudson
stock, and the estimated number of shares of TrustCo stock to be exchanged for
each share of Hudson stock, on June 23, 2000, the last trading day before we
announced our initial offer to acquire Hudson, and on October ___, 2000, the
last trading day before the date of this Prospectus. Because the value of the
TrustCo stock you will receive per share of Hudson stock is fixed at $6.80, the
number of shares of TrustCo stock you will receive will fluctuate as the market
price of TrustCo stock changes. The prices set forth below do not reflect the
effect of the 15% stock split declared by TrustCo's board of directors on August

DIVIDEND POLICY OF TRUSTCO (PAGE 15)


            The holders of TrustCo stock receive dividends if and when declared
by the TrustCo board of directors out of legally available funds. Our past
practice has been to pay dividends at a rate of 65% to 85% of operating
earnings. For each of the past two fiscal quarters, we have paid a quarterly
cash dividend of $0.15 per share, and, on August 15, 2000, TrustCo's board of
directors declared a quarterly dividend of $0.15 per share, payable October 2,
2000 to shareholders of record on September 8, 2000. Also on August 15, 2000,
TrustCo's board approved a 15% stock split, with the additional shares of
TrustCo common stock to be payable on November 13, 2000 to shareholders of
record on October 20, 2000. Following completion of the offer and a
TrustCo-Hudson merger, we expect to continue paying quarterly cash dividends on
a basis consistent with our past practice. However, the declaration and payment
of dividends will depend upon business conditions, operating results, capital
and reserve requirements and consideration of other relevant factors. No
assurance can be given that we will continue to pay dividends on our stock in
the future.

THE OFFER (PAGE 32)


            WE ARE OFFERING TO EXCHANGE A COMBINATION OF SHARES OF TRUSTCO STOCK
AND CASH TOTALING $17.00 FOR EACH SHARE OF HUDSON STOCK

            We are offering, upon the terms and subject to the conditions set
forth in this Prospectus and in the letter of transmittal, to exchange a
combination of shares of TrustCo stock and cash totaling $17.00 for each
outstanding share of Hudson stock that is validly tendered on or before the
expiration date and not properly withdrawn. The stock component of the exchange
consideration will consist of TrustCo stock an aggregate value of $6.80, and the
cash component will be $10.20. The term "expiration date" means 12:00 midnight,
New York time, on __________, 2000, unless we extend the period of time for
which this offer is open, in which case the term "expiration date" means the
latest time and date on which the offer, as so extended, expires. We are not
making any assurance that we will exercise our right to extend our offer,
although we currently intend to do so until all conditions have been satisfied
or waived.

            The following table shows the number of shares of TrustCo stock we
will pay to Hudson stockholders in exchange for each share of Hudson stock
assuming various average closing prices of TrustCo stock. The actual number of
shares of TrustCo stock that Hudson stockholders will receive will be based upon
the average closing price of the TrustCo stock on the Nasdaq over a 20-day
period ending 5 days before the closing on our offer.

                        of the Delaware General Corporation Law and certain
                        anti-takeover provisions found in Hudson's Certificate
                        of Incorporation do not apply to or otherwise restrict
                        our offer and the proposed TrustCo-Hudson merger; and

            o           if required under the rules of the Nasdaq Stock Market,
                        the approval by our stockholders of the issuance of
                        TrustCo stock in our offer for Hudson.

            OUR OFFER IS CURRENTLY SCHEDULED TO EXPIRE ON _______, 2000

            Our offer is currently scheduled to expire on __________, 2000.
However, we currently intend to extend our offer from time to time as necessary
until all the conditions to the offer have been satisfied or waived. See "THE
EXCHANGE OFFER--Extension, Termination and Amendment."

            OUR OFFER MAY BE EXTENDED, TERMINATED OR AMENDED

            We expressly reserve the right, in our sole discretion, at any time
or from time to time, to extend the period of time during which our offer
remains open, and we can do so by giving oral or written notice of such
extension to the exchange agent. If we decide to extend our offer, we will make
an announcement to that effect no later than 9:00 A.M., New York time, on the
next business day after the previously scheduled expiration date. We are not
making any assurance that we will exercise our right to extend our offer,
although we currently intend to do so until all conditions have been satisfied
or waived. During any such extension, all shares of Hudson stock previously
tendered and not withdrawn will remain subject to the offer, subject to your
right to withdraw your Hudson shares.

            Subject to the SEC's applicable rules and regulations, we also
reserve the right, in our sole discretion:


            o           to delay our acceptance for exchange or our exchange of
                        any shares of Hudson stock pursuant to our offer, or to
                        terminate our offer and not accept for exchange or
                        exchange any shares of Hudson stock not previously
                        accepted for exchange or exchanged, upon the failure of
                        any of the conditions of the offer to be satisfied on or
                        prior to the expiration date, or upon the failure of the
                        condition relating to regulatory approvals to be
                        satisfied at any time after the expiration date
                        regardless of whether we previously accepted for
                        exchange or exchanged any shares of Hudson stock; and


            o           to waive any condition (other than the conditions
                        relating to the TrustCo stockholder approval, regulatory
                        approvals and the effectiveness of the Registration
                        Statement for the shares of TrustCo stock to be issued
                        in our offer) or otherwise to amend the offer in any
                        respect, by giving oral or written notice of such delay,
                        termination or amendment to the exchange agent and by
                        making a public announcement.

            We will follow any extension, termination, amendment or delay, as
promptly as practicable, with a public announcement. Subject to applicable law
(including rules 14d-4(c) and 14d-6(d) under the 1934 Act, which require that
any material change in the information published, sent or given to the
stockholders in connection with the offer be promptly sent to stockholders in a
manner reasonably designed to inform them of such change) and without limiting
the manner in which we may choose to make any public announcement, we assume no
obligation to publish, advertise or otherwise communicate any such public
announcement other than by making a release to the Dow Jones News Service.

            Upon the terms and subject to the conditions of our offer
(including, if the offer is extended or amended, the terms and conditions of any
such extension or amendment), we will accept for exchange, and will exchange,
shares of Hudson stock validly tendered and not properly withdrawn as promptly
as practicable after the expiration date, and promptly after they are tendered
during any subsequent offering period.

                        agent at such address, or those shares must be tendered

reference in this document, contains forward-looking statements with respect to

information relating to the exchange offer. Also, statements preceded by,

TrustCo intends to commence an exchange offer for Cohoes on October ___, 2000.
Neither this offer nor the proposed TrustCo-Hudson merger is conditioned on the

                SELECTED HISTORICAL AND PRO FORMA PER SHARE DATA
                                   (unaudited)


            The following tables show book value per share as of June 30, 2000
for each of TrustCo, Hudson, Cohoes, TrustCo/Hudson combined and
TrustCo/Hudson/Cohoes combined. The per share information for TrustCo does not
reflect the effect of the 15% stock split declared by TrustCo's board of
directors on August 15, 2000. Also shown is historical net income per share and
dividends per share information for each of TrustCo, Hudson and Cohoes for the
six months ended June 30, 2000 and the twelve months ended December 31, 1999 and
similar pro forma information for TrustCo/Hudson combined and
TrustCo/Hudson/Cohoes combined for the six months ended June 30, 2000. Also
shown, for comparative purposes, is historical net income per share information
for Hudson for the twelve months ended March 31, 2000 and Cohoes for the twelve
months ended June 30, 2000, their most recently reported fiscal year ends.


            The information concerning Hudson and Cohoes is derived from
previously filed Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and
previously released press releases. TrustCo does not make any representation
with respect to either Hudson or Cohoes amounts and has not performed any
procedures to ensure their accuracy or reasonableness.

            The information shown for TrustCo has been prepared from historical
financial information from previously filed Annual Reports on Form 10-K,
Quarterly Reports on Form 10-Q and previously released press releases.

            The information is for illustrative purposes only. The companies
would likely have performed differently had they always been combined. The
information should not be relied on as an indication of future results that the
combined company will experience after the transaction is completed. The pro
forma results are also not necessarily indicative of the future financial
position or future operating results of the combined company. In particular,
TrustCo expects to achieve operating cost savings as a result of the Hudson and
Cohoes transactions. See "BACKGROUND OF THE EXCHANGE OFFER--Benefits of the
transaction" No adjustments have been included in the combined pro forma
operating amounts for the anticipated operating cost savings.

(1) For the Fiscal Year-End amount, TrustCo has a fiscal year end of December
31, 1999, Cohoes has a fiscal year end of June 30, 2000 and Hudson has a fiscal
year end of March 31, 2000.

(2) Equivalent dividends per share are calculated for Hudson by multiplying the
historical TrustCo dividends per share by the estimated transaction exchange
rate of 0.56, which is calculated by dividing the Hudson acquisition price of
$6.80 by the $12.25 market value of TrustCo stock on September 28, 2000.

(3) Equivalent dividends per share are calculated for Cohoes by multiplying the
historical TrustCo dividends per share by the estimated transaction exchange
rate of 0.59, which is calculated by dividing the Cohoes acquisition price of
$7.20 by the $12.25 market value of TrustCo stock on September 28, 2000.

(4) Because the exact exchange ratio of TrustCo stock to Hudson stock has not
yet been determined, the pro forma estimated dividend rate is subject to
fluctuation.

                SELECTED PRO FORMA COMBINED FINANCIAL INFORMATION

            The following tables show selected pro forma financial data for
TrustCo/Hudson combined, TrustCo/Cohoes combined and TrustCo/Hudson/Cohoes
combined.

            The information concerning Hudson and Cohoes is derived from
previously filed Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and
previously released press releases. TrustCo does not make any representation
with respect to either Hudson or Cohoes amounts and has not performed any
procedures to ensure their accuracy or reasonableness.

            The information shown for TrustCo has been prepared from historical
financial information from previously filed Annual Reports on Form 10-K,
Quarterly Reports on Form 10-Q and previously released press releases.

            The information is for illustrative purposes only. The companies
would likely have performed differently had they always been combined. The
information should not be relied on as an indication of future results that the
combined company will experience after the transaction is completed. The pro
forma results are also not necessarily indicative of the future financial
position or future operating results of the combined company. In particular,
TrustCo expects to achieve operating cost savings as a result of the Hudson and
Cohoes transactions. See "BACKGROUND OF THE EXCHANGE OFFER--Benefits of the
transaction". No adjustments have been included in the combined pro forma
operating amounts for the anticipated operating cost savings.

                                  RISK FACTORS


            In deciding whether to tender your shares of Hudson stock pursuant
to our offer, you should read carefully this Prospectus and the documents to
which we refer you. You should also carefully consider the following factors.


IF WE DO NOT SUCCESSFULLY INTEGRATE TRUSTCO'S AND HUDSON'S OPERATIONS, THE
ANTICIPATED BENEFITS OF THE ACQUISITION OF HUDSON MAY NOT BE FULLY REALIZED

            If we complete the offer and our proposed merger, we will integrate
two companies that have previously operated independently. We have not
previously acquired an organization where there is the potential for management
to be uncooperative in the integration process. There can be no assurance that
we will not encounter difficulties in our efforts to integrate the operations of
Hudson with our operations. The diversion of the attention of management to the
integration effort and any difficulties encountered in combining our operations
could adversely affect the combined company's business and results of
operations. These risks could be increased if we complete our proposed
acquisition of Cohoes in that we will integrate three companies that have
previously operated independently.


THERE IS NO GUARANTEE THAT WE WILL ACHIEVE OUR PROJECTED COST SAVINGS OF
APPROXIMATELY $15 MILLION on a PRE-TAX basis


            We have estimated that, by combining TrustCo and Hudson, we could
realize cost savings of approximately $15 million. See "BACKGROUND OF THE
EXCHANGE OFFER--Benefits of the Transaction." Because we have been unable to
discuss any of our cost savings assumptions or analyses with management of
Hudson and because we have had no access to Hudson's internal information about
its operations, in connection with the preparation of our cost savings
estimates, we have relied on publicly available information concerning Hudson,
our general knowledge of the markets in which we and Hudson compete and our past
experience with respect to our own operations and our integration of acquired
financial institutions. If we were permitted access to Hudson's internal
information about its operations or if we were able to discuss our assumptions
or analyses with Hudson's management, our cost savings estimate might differ. No
assurance can be given that the estimated cost savings will be achieved or will
occur in the time period anticipated. Furthermore, there can be no assurance
that cost savings which are realized will not be offset by increases in other
expenses, other charges to earnings or losses of revenue, including losses due
to problems in integrating the Hudson operations into TrustCo.


            We expect to realize a significant portion of the cost savings
through integrating the operations of our subsidiary, Trustco Bank, National
Association, with Hudson's subsidiary, Hudson River Bank & Trust Company, which
may require additional regulatory approvals. These significant cost savings will
not be realized unless and until we are able to integrate these operations.
While we are not able to specifically quantify this portion of our estimated
cost savings, we believe that it would constitute a majority of our estimated
cost savings. Receipt of any required regulatory approvals for this integration
is not a condition to the offer or the merger of Hudson and TrustCo.


THERE IS NO GUARANTEE THAT WE WILL NOT SUFFER NET REVENUE RUN-OFF AS A RESULT OF
INTEGRATING HUDSON'S BUSINESSES INTO OURS

            In formulating our earnings estimates, we have not assumed any net
run-off of revenue attributable to our acquisition of Hudson. This assumption is
based on our prior acquisition experience where we have been able to grow net
interest income and non-interest income while achieving targeted cost savings.
In addition, we have not made any decisions with respect to branch closings
because we do not have access to internal information of Hudson from which we
would expect to make such decisions. Accordingly, our earnings estimates do not
assume the closure of any Hudson (or TrustCo) branches, although we would
anticipate that certain branches will be closed. We believe that any revenue
reduction


                                       26
<PAGE>

resulting from any branch closings would be offset by additional cost savings
associated with such branch closings. If we were permitted access to non-public
information regarding Hudson's business plans and operations, our assumption of
no net revenue run-off might differ. Although we intend generally to integrate
Hudson's operations and implement our cost savings measures in a manner that is
designed to minimize the loss of revenues, there can be no assurance that some
revenue will not be lost. Factors that could cause a loss of revenues include
unanticipated loss of customers due to a lack of customer acceptance of our
deposit, lending and investment products.

THERE CAN BE NO ASSURANCE THAT THE INTEGRATION PROCESS WILL NOT BE ADVERSELY
AFFECTED IF HUDSON'S SENIOR EXECUTIVE MANAGEMENT OR OTHER EMPLOYEES ARE
UNCOOPERATIVE IN THAT PROCESS

            As noted above, we have not previously engaged in an acquisition
where there is the potential for management and other employees to be
uncooperative with us in the integration process. Our proposal is not dependent
upon the retention of Hudson's senior executive management, and we have no
reason to believe that Hudson employees below the level of senior executive
management would be uncooperative in the integration process, either before the
completion of our proposed merger or thereafter. However, there can be no
assurance that there will not be some level of uncooperativeness on the part of
Hudson's senior executive management and/or its other employees which could
adversely affect the integration process.

YOUR BOARD OF DIRECTORS MAY DELAY SATISFACTION OF CERTAIN CONDITIONS TO OUR
OFFER

            Several of the conditions to our offer will require action by the
Hudson board of directors. See "THE EXCHANGE OFFER--Certain Conditions of the
Exchange Offer." There can be no assurance that the Hudson board will take
action to cause the satisfaction of these conditions to our offer.

THERE IS NO GUARANTEE THAT WE WILL BE SUCCESSFUL IN OUR ATTEMPT TO MERGE WITH
BOTH HUDSON AND COHOES


             TrustCo's separate exchange offers for each of Hudson and Cohoes
are not conditioned on the successful completion of the other. Accordingly, it
is possible that the exchange offers could result in: (i) a three-way
combination of TrustCo, Hudson and Cohoes; (ii) a combination of TrustCo and
Hudson; (iii) a combination of TrustCo and Cohoes; or (iv) neither exchange
offer could be successfully consummated. TrustCo does not anticipate, however,
that the nature of its business operations would vary materially as a
consequence of its combining with only one of, as opposed to both of, Hudson and
Cohoes. The businesses of Hudson and Cohoes are similar in that both are
community-oriented financial institutions with a primary focus on obtaining
deposit accounts from the general public and originating primarily residential
mortgage loans and, to a lesser extent, commercial and multi-family real estate
loans. The market areas of TrustCo, Hudson and Cohoes are adjacent and
complementary to one another, but, because the direct overlap of their branch
locations is not extensive, the costs savings and efficiencies that could be
anticipated to result from only a single acquisition would not be materially
different from those to be anticipated from that acquisition even if both
acquisitions were to be consummated. See the pro forma financial information on
pages 15 and 22, which reflects the alternative possibilities for the successful
completion of the respective exchange offers described above.

THE ACTUAL VALUE OF THE TRUSTCO COMMON STOCK RECEIVED BY HUDSON'S SECURITY
HOLDERS IN EXCHANGE FOR SHARES OF HUDSON COMMON STOCK MAY BE MORE THAN OR LESS
THAN $6.80 PER SHARE AT THE TIME OF EXCHANGE

            The actual value of the TrustCo common stock received by Hudson's
security holders in exchange for shares of Hudson common stock may be more than
or less than $6.80 per share at the time of exchange. This results from the fact
that the exact number of shares of TrustCo common stock that will comprise the
stock component of the consideration offered by TrustCo in exchange for



                                       27
<PAGE>

Hudson common stock will be determined based upon the average closing price of
the TrustCo stock on the Nasdaq over a twenty-day period, with the twenty-day
period ending five days prior to the closing of the offer. It is possible that,
in this five day interim period, the closing price of TrustCo common stock may
fluctuate such that it is more or less than the foregoing average price used to
calculate the exact exchange ratio.

IF TRUSTCO IS ABLE TO CONSUMMATE BOTH THE HUDSON MERGER AND THE COHOES MERGER,
THERE IS A RISK THAT TRUSTCO MAY ENCOUNTER DIFFICULTY IN MAINTAINING ITS CURRENT
DIVIDEND LEVEL


            Because the actual number of shares of TrustCo common stock that
Hudson stockholders will receive is not yet fixed, the estimated amount of cash
dividends Hudson stockholders will receive will fluctuate with the value of
TrustCo common stock. In the past five years, on a compounded basis, TrustCo has
achieved an 16% annual growth rate in its per share dividend. During the year
ended December 31, 1999, TrustCo paid out approximately 79% of its net income in
the form of cash dividends. Although TrustCo believes that, upon the completion
of its proposed acquisition of Hudson, it will have the resources to continue to
pay dividends consistent with its past practices, the declaration and payment of
dividends is within the discretion of TrustCo's board of directors and, to the
extent that TrustCo's board determines that the payment of such dividends may
have an adverse effect upon TrustCo's growth potential, level of customer
service or financial condition, the board may decide to reduce dividend payment
rates.

IF SUCCESSFUL, THE OFFER WILL RESULT IN  the creation of goodwill

            If TrustCo's offers to acquire Hudson and Cohoes are successful,
TrustCo will account for the acquisitions as a purchase business combination and
will record goodwill on its financial statements in an amount equal to the
difference between the fair market value of Hudson's and Cohoes assets and
liabilities and the purchase price paid by TrustCo for Hudson and Cohoes. If the
transactions had occurred on June 30, 2000, TrustCo estimates that its
acquisitions of Hudson and Cohoes would have resulted in the creation of
goodwill in the amounts of $57.0 million and $24.6 million, respectively, and
that the total amount of goodwill recorded on TrustCo's financial statements
(including the existing amounts of goodwill on Cohoes' and Hudson's financial
statements) would total $94.5 million. TrustCo will amortize the goodwill over a
period of 15 to 20 years. The amortization of the goodwill will result in
charges against TrustCo's future earnings and could result in TrustCo having
fewer resources for paying dividends to shareholders. The section of this
prospectus headed "Pro Forma Combined Financial Information" contains a more
detailed analysis of the effect of the proposed acquisitions on the operations
of the resulting company. The actual amount of goodwill created in the proposed
acquisitions will depend upon the fair market value of Hudson's and Cohoes'
assets and liabilities at the time the acquisitions are completed. There can be
no assurance that the goodwill created by the acquisitions will be greater or
less than that projected in the pro forma data.

If successful, the offer will result in a book value per share DILUTION

            If successful, TrustCo's offers to acquire Hudson and Cohoes would
result in dilution of the tangible book value per share of Hudson and Cohoes
stockholders. As of June 30, 2000, the tangible book value per share of TrustCo,
Hudson and Cohoes was $3.30, $12.33 and $15.13 respectively. Upon completion of
TrustCo's proposed acquisition of Cohoes and Hudson, TrustCo's pro forma
tangible book value would be $3.39 per share. If only the TrustCo-Hudson merger
occurs, TrustCo's pro forma tangible book value would be $3.42 per share.

                        BACKGROUND OF THE EXCHANGE OFFER

PAST CONTACTS

            From time to time, TrustCo is involved in due diligence
investigations, discussions and negotiations concerning possible business
combination transactions with other financial institutions. TrustCo generally
seeks to acquire financial institutions that would: (i) complement its overall
strategic focus; (ii) provide opportunities for growth in markets where the
target financial institution conducts business; and (iii) improve TrustCo's
retail banking franchise.


            On August 26, 1999, Robert A. McCormick, TrustCo's President and
Chief Executive Officer, and Robert T. Cushing, TrustCo's Vice President and
Chief Financial Officer, met with Carl A. Florio, Hudson's Chief Executive
Officer, to discuss TrustCo's plan of putting together approximately six local
banks under TrustCo management to produce a strong locally owned and managed
entity. At that meeting, McCormick proposed a price of $14 per share in TrustCo
stock for each share of Hudson, which was approximately 1.3 times the market
price of Hudson common stock at that time. At the August 26, 1999 meeting, Mr.
Florio indicated that Hudson had no present intention of engaging in such a
transaction with TrustCo and that he believed Hudson's board of directors
supported this view. Two days later, without further discussion or
investigation, Mr. Florio confirmed to TrustCo that Hudson had no interest in
such a merger. According to the proxy statement provided to shareholders by
Hudson in connection with its proposed merger with Cohoes, Mr. Florio had, prior
to the meeting with Mr. McCormick, already discussed a potential merger with
Harry L. Robinson, Cohoes' President and Chief Executive Officer, and the chief
financial officers of Hudson and Cohoes had also already met to discuss such a
merger.


            On April 25, 2000, Hudson and Cohoes announced that they had entered
into their merger agreement and the related option agreement. Following
announcement of the proposed Hudson-Cohoes merger, TrustCo reviewed its
strategic options, including the possibility of proceeding with one or more
offers for either or both of Hudson and Cohoes.


            On June 8, 2000, TrustCo sent a letter to Mr. Earl Schram, Jr., the
Chairman of the Board of Hudson, proposing a merger of TrustCo and Hudson.
Pursuant to the proposal, TrustCo would acquire Hudson in a merger (the
"TrustCo-Hudson Merger") in which each share of Hudson's common stock would be
exchanged for shares of TrustCo common stock valued at $14.00. On June 23, 2000,
Hudson informed TrustCo that Hudson's Board of Directors had unanimously
rejected the proposed TrustCo-Hudson Merger.

            On June 26, 2000, TrustCo publicly announced its intention to
commence a tender offer to exchange shares of TrustCo common stock valued at
$14.00 for each share of Hudson's common stock. Also on June 26, 2000, Hudson
publicly announced that it remained fully committed to the proposed merger with
Cohoes.


            On July 7, 2000, TrustCo filed a Form 425 with the SEC for the
purpose of disclosing that it had published a newspaper notice to shareholders
of Hudson and Cohoes, briefly describing that the boards of both Hudson and
Cohoes had rejected the TrustCo offer, and emphasizing that a Hudson/Cohoes
merger may not be in the best interests of the Hudson and Cohoes shareholders.


            On July 10, 2000, TrustCo sent a letter to Mr. Schram, requesting a
meeting to discuss the proposed TrustCo-Hudson combination. On July 21, 2000,
Hudson rejected TrustCo's request for such a meeting.

            On July 11, 2000, TrustCo filed proxy materials with the SEC for the
purpose of soliciting votes by Hudson and Cohoes stockholders against the
proposed Hudson-Cohoes merger .



                                       29
<PAGE>

            On July 14, 2000, TrustCo filed a Form 425 with the SEC for the
purpose of disclosing that it had published a newspaper notice to shareholders
of Hudson and Cohoes, briefly describing the parameters of the offer and asking
for the support of Hudson and Cohoes shareholders.

            On July 21, 2000, TrustCo filed a Form 425 with the SEC for the
purpose of disclosing that it had published a newspaper notice to shareholders
of Hudson and Cohoes, comparing the dividend yield and other financial
performance data of Hudson, Cohoes and TrustCo.


            On July 31, 2000, TrustCo began to solicit proxies from the
shareholders of both Hudson and Cohoes in opposition to the proxies solicited by
the management for the August 17, 2000 meetings of the shareholders of Hudson
and Cohoes to consider and vote upon the proposed merger of Hudson and Cohoes
(the "Hudson-Cohoes Merger").

            On August 18, 2000, Cohoes announced that its shareholders did not
approve the Hudson-Cohoes Merger, although Hudson announced that its
shareholders had approved the merger.

            On August 24, 2000, Mr. McCormick and Mr. Cushing met again with Mr.
Florio and Mr. Schram to discuss a potential business combination between
TrustCo and Hudson. Mr. Florio indicated that he would discuss TrustCo's
interest with Hudson's board of directors. On August 30, 2000, TrustCo sent a
letter to Mr. Schram and Mr. Florio that outlined the terms of a potential
transaction between TrustCo and Hudson. Mr. Florio subsequently advised TrustCo
that its proposal would be discussed at Hudson's board meeting on September 28,
2000. After that meeting, Hudson advised TrustCo that the Hudson board had
decided not to pursue a potential business combination with TrustCo.

            On September 28, 2000, Hudson and Cohoes publicly announced the
termination of the Hudson-Cohoes Merger agreement because it was not approved by
the requisite vote of the shareholders of Cohoes at the special meeting held on
August 17, 2000. Hudson and Cohoes also publicly announced the amendment of
their agreement granting each company an option to purchase up to 19.9% of the
issued and outstanding shares of the other should any third party pursue a
transaction with Hudson or Cohoes (the "Stock Option Agreements"). Hudson and
Cohoes publicly announced that the amendment capped the economic value of their
respective stock options in each other at $3.5 million.


PURPOSE OF THE EXCHANGE OFFER; THE TRUSTCO-HUDSON MERGER


            The purpose of our offer (the "Exchange Offer") is to acquire
control of, and ultimately the entire equity interest in, Hudson and to
consolidate the operations of Hudson and TrustCo to achieve operational
efficiencies and cost savings. TrustCo would not make the Exchange Offer if it
could not effect the TrustCo-Hudson Merger and, consequently, the Exchange Offer
is conditioned upon the removal of various impediments to consummation of the
TrustCo-Hudson Merger. As soon as practicable after consummation of the Exchange
Offer, TrustCo intends to cause to occur: (i) the merger of Hudson with a
subsidiary of TrustCo pursuant to which each outstanding share of Hudson common
stock ("Hudson Common Stock") (except for treasury shares and shares held by
TrustCo or any subsidiary of TrustCo other than in a fiduciary capacity) would
be converted into the right to receive shares of TrustCo common stock ("TrustCo
Common Stock") with an aggregate value equal to $6.80 and $10.20 in cash; and
(ii) the integration of the operations of Hudson River Bank & Trust Company with
Trustco Bank, National Association ("Trustco Bank") or another subsidiary of
TrustCo.


BENEFITS OF THE TRANSACTION

            Following the TrustCo-Hudson Merger, TrustCo intends to consolidate
all supervisory functions of Hudson into TrustCo, transfer all remaining assets
of Hudson to Trustco Bank and consolidate the


                                       30
<PAGE>


business and operations of Hudson River Bank & Trust Company with Trustco Bank,
resulting in operational efficiencies and cost savings.

            TrustCo believes that the integration of Trustco Bank and Hudson
River Bank & Trust Company will provide increased opportunities for growth and
diversification in and service to the market served by each organization and
added flexibility in responding to various factors currently influencing the
banking and financial services industries, including rapid technological and
regulatory changes, increased competition and the geographic expansion of
markets. The TrustCo-Hudson Merger will allow TrustCo to extend its natural
marketplace in New York and is expected to result in greater economies of scale
through coordination of intra-market operations and a stronger financial
position through an increased asset base. Although estimates of specific cost
savings resulting from the consolidation are inherently subjective, TrustCo
presently believes that, if the TrustCo-Hudson Merger and the integration of
Trustco Bank with Hudson River Bank & Trust Company are consummated, TrustCo
would be able to achieve pre-tax cost savings of approximately $8 million in the
first year, and an additional $7 million in the second year following the
TrustCo-Hudson Merger. See "SELECTED PRO FORMA COMBINED FINANCIAL INFORMATION."


OFFER TO ACQUIRE COHOES


            On June 8, 2000, TrustCo sent a letter to Mr. Duncan MacAffer, the
Chairman of the Board of Cohoes, proposing the merger of TrustCo and Cohoes.
Pursuant to the proposal, TrustCo would acquire Cohoes in a merger (the
"TrustCo-Cohoes Merger") in which each share of Cohoes common stock would be
exchanged for shares of TrustCo Common Stock valued at $16.00. On June 23, 2000
, Cohoes informed TrustCo that a merger with TrustCo was contrary to Cohoes'
strategic business plan and declined to have any discussions with TrustCo.

            On June 26, 2000, TrustCo publicly announced its intention to
commence a tender offer to exchange shares of TrustCo Common Stock valued at
$16.00 for each share of Cohoes' common stock. Also on June 26, 2000, Cohoes
publicly announced that it remained fully committed to the proposed merger with
Hudson.

            TrustCo actively solicited Cohoes stockholders to vote against the
Hudson-Cohoes Merger. Although Hudson's stockholders approved the Hudson-Cohoes
Merger at Hudson's annual meeting of stockholders on August 17, 2000, Cohoes'
stockholders, at a special meeting on the same date, failed to approve the
merger.

            TrustCo has nominated M. Norman Brickman, Thomas P. Collins, Thomas
O. Maggs and Peter A. Pastore as candidates for election to Cohoes' board of
directors at Cohoes' 2000 annual meeting of shareholders and has filed a
preliminary proxy statement with the Securities and Exchange Commission with
respect to its solicitation of proxies for use at Cohoes' annual meeting for the
purpose of electing Messrs. Brickman, Collins, Maggs and Pastore.

            TrustCo expects to commence its exchange offer for Cohoes on October
___, 2000 by mailing a prospectus and the related letter of transmittal to
Cohoes stockholders. In the exchange offer, TrustCo would exchange a combination
of shares of TrustCo Common Stock and cash totaling $18.00 for each outstanding
share of Cohoes common stock validly tendered and not withdrawn. The stock
component of the Cohoes exchange consideration will be comprised of TrustCo
Common Stock with an aggregate value equal to $7.20, and the cash component will
be $10.80 net. If TrustCo's exchange offer is successful, TrustCo intends to
follow the exchange offer with the TrustCo-Cohoes Merger. TrustCo expects to
file shortly an application with the Federal Reserve Board to obtain the
regulatory approvals necessary to complete that exchange offer and the
TrustCo-Cohoes Merger. Promptly after the SEC declares that registration
statement effective, TrustCo intends to file with



                                       31
<PAGE>

the SEC proxy materials to be used for soliciting the approval by TrustCo's
stockholders of the issuance of TrustCo Common Stock in the Cohoes exchange
offer and the TrustCo-Cohoes Merger.

            The consummation of the Cohoes exchange offer on the part of TrustCo
is subject to the same or similar conditions (or the waiver thereof) as this
Exchange Offer. However, neither the consummation of the Cohoes exchange offer
nor the TrustCo-Cohoes Merger is a condition precedent to this Exchange Offer.

MAXIMUM EXPECTED POST-MERGER DIVIDEND


            During the year ended December 31, 1999, TrustCo paid out
approximately 79% of its net income in the form of cash dividends. TrustCo
anticipates (assuming that it realizes the estimated cost savings from combining
with Hudson and continues to pay the same percentage of income in the form of
cash dividends) that the dividend rate for the year ended December 31, 1999
would have been $0.60 per share, which is the same as TrustCo's annualized
dividend rate of $0.60 per share for 2000.


                               THE EXCHANGE OFFER

            The following description contains, among other information, a
summary of the Exchange Offer and the related letter of transmittal (the "Letter
of Transmittal") and is qualified in its entirety by reference to the full text
of the Letter of Transmittal which is incorporated herein by reference and
attached hereto as Appendix A to this Prospectus. SHAREHOLDERS ARE URGED TO READ
CAREFULLY THE LETTER OF TRANSMITTAL.

GENERAL


            TrustCo hereby offers, upon the terms and subject to the conditions
of the Exchange Offer described in this Prospectus and the related Letter of
Transmittal, to exchange $17.00 in a combination of shares of TrustCo Common
Stock and cash (the "Exchange Consideration") for each outstanding share of
Hudson Common Stock validly tendered on or prior to the Expiration Date (as
defined herein) and not withdrawn. A tendering Hudson shareholder may, by
properly completing the Letter of Transmittal, elect to receive the Exchange
Consideration for his or her Hudson Common Stock.

            The number of shares of TrustCo Common Stock constituting a part of
the Exchange Consideration for purposes of the Exchange Offer will be calculated
with reference to the average closing price of the TrustCo Common Stock on the
Nasdaq for the 20-day period ending 5 days prior to the closing date under the
Exchange Offer. Since the value of the TrustCo Common Stock component of the
Exchange Consideration is fixed at $6.80 per share of Hudson Common Stock
exchanged, the number of shares of TrustCo Common Stock that a tendering Hudson
shareholder will receive under the Exchange Offer will fluctuate as the market
price of the TrustCo Common Stock fluctuates. Based on the closing sales price
of a share of TrustCo Common Stock as reported on Nasdaq on __________________,
2000, tendering holders of Hudson Common Stock would receive _____ shares of
TrustCo Common Stock as the Exchange Consideration. TRUSTCO RESERVES THE RIGHT
TO AMEND THE EXCHANGE OFFER, INCLUDING THE COMPOSITION OR AMOUNT OF THE EXCHANGE
CONSIDERATION, FOR ANY REASON. IF TRUSTCO SO AMENDS THE EXCHANGE OFFER, IT WILL
EXTEND THE EXCHANGE OFFER FOR A PERIOD OF TEN BUSINESS DAYS IF THE EXCHANGE
OFFER IS SCHEDULED TO EXPIRE PRIOR THERETO.

            The term "Expiration Date" means 12:00 midnight, New York City time,
on _______________, 2000, unless and until TrustCo extends the period of time
for which the Exchange Offer is open, in which event the term "Expiration Date"
means the latest time and date at which the Exchange Offer, as so extended by
TrustCo, expires. TrustCo presently anticipates electing to extend the Exchange
Offer from time to time until such time as all of the conditions to the Exchange
Offer have been satisfied or waived; however, TrustCo will not be obligated to
do so. See "THE EXCHANGE OFFER--Certain Legal Matters" and "-- Certain
Conditions of the Exchange Offer."



                                       32
<PAGE>

            Tendering shareholders will not be obligated to pay any charges or
expenses of ChaseMellon Shareholder Services, the exchange agent for this
Exchange Offer (the "Exchange Agent"), or any brokerage commissions. Except as
set forth in Instruction 6 of the Letter of Transmittal, transfer taxes on the
exchange of Hudson Common Stock pursuant to the Exchange Offer will be paid by
or on behalf of TrustCo.


            TrustCo's obligation to exchange shares of TrustCo Common Stock and
cash for Cohoes Common Stock pursuant to the Exchange Offer is subject to a
number of conditions referred to below under "THE EXCHANGE OFFER--Certain
Conditions of the Exchange Offer ," including a minimum tender condition, a
regulatory approval condition and the other conditions described below.

            If by 12:00 midnight, New York City time, on _________________,
2000, or any later time to which the Expiration Date and this Exchange Offer
have been extended, all of the above conditions have not been satisfied or
waived, TrustCo may elect either to: (i) extend the Expiration Date and this
Exchange Offer and retain all shares of Hudson Common Stock theretofore tendered
until the expiration of the Expiration Date and this Exchange Offer, as
extended, subject to the right of a tendering shareholder to withdraw his or her
Hudson Common Stock; (ii) waive the remaining conditions (other than the
Regulatory Approval Condition, the TrustCo Stockholder Approval Condition and
the effectiveness of this Registration Statement), extend the Exchange Offer for
a period of ten business days if the Exchange Offer is scheduled to expire prior
thereto and thereafter exchange all tendered shares of Hudson Common Stock; or
(iii) terminate the Exchange Offer and exchange none of the Hudson Common Stock
and return all tendered shares of Hudson Common Stock. TrustCo will not accept
for exchange any shares of Hudson Common Stock pursuant to the Exchange Offer
until such time as the Regulatory Approval Condition and the TrustCo Stockholder
Approval Condition have been satisfied and the Registration Statement has become
effective. See "THE EXCHANGE OFFER -- Certain Legal Matters" and "--Certain
Conditions of the Exchange Offer--REGULATORY APPROVAL CONDITION", "--TRUSTCO
STOCKHOLDER APPROVAL CONDITION" and "--EFFECTIVE REGISTRATION STATEMENT."


            A request is being made to Hudson for use of Hudson's shareholder
list and security position listing for the purpose of disseminating the Exchange
Offer to holders of Hudson Common Stock. The Prospectus and the related Letter
of Transmittal will be mailed to record holders of Hudson Common Stock and will
be furnished to brokers, banks and similar persons whose names or the names of
whose nominees appear on the shareholder list or, if applicable, who are listed
as participants in a clearing agency's security position listing for subsequent
transmittal to beneficial owners of Hudson Common Stock.

EXTENSION, TERMINATION AND AMENDMENT


            TrustCo expressly reserves the right, in its sole discretion, at any
time on or prior to the Expiration Date, to extend the period of time during
which the Exchange Offer is to remain open by giving oral or written notice of
such extension to the Exchange Agent. There can be no assurance that TrustCo
will exercise its right to extend the Expiration Date and this Exchange Offer,
although it is presently anticipated that the Expiration Date and this Exchange
Offer will be extended in order to permit the conditions to be satisfied. If
TrustCo amends the Exchange Offer, it will extend the Expiration Date and this
Exchange Offer for a period of ten business days if the Exchange Offer is
scheduled to expire prior thereto. During any such extension, all shares of
Hudson Common Stock previously tendered and not withdrawn will remain subject to
the Exchange Offer, subject to the right of a tendering shareholder to withdraw
his or her Hudson Common Stock. See "THE EXCHANGE OFFER -- Withdrawal Rights."
TrustCo also reserves the right to delay acceptance for exchange of, or exchange
of, any Hudson Common Stock pursuant to the Exchange Offer, regardless of
whether such shares of Hudson Common Stock were theretofore accepted for
exchange, and to amend or terminate the Exchange Offer



                                       33
<PAGE>


and not accept for exchange or exchange any Hudson Common Stock not theretofore
accepted for exchange, or exchanged, upon the failure of any of the conditions
of the Exchange Offer to be satisfied or waived on or before the Expiration
Date. Any such extension, termination, amendment or delay will be followed as
promptly as practicable by public announcement thereof, such announcement in the
case of an extension to be issued no later than 9:00 A.M., New York City time,
on the next business day after the previously scheduled Expiration Date. Without
limiting the manner in which TrustCo may choose to make such public
announcement, TrustCo will not, unless otherwise required by rules of the SEC,
have any obligation to make any such public announcement other than by making a
release to the Dow Jones News Service. If, prior to the Expiration Date, TrustCo
increases the consideration offered to holders of Hudson Common Stock, such
increase will be applicable to all holders whose shares of Hudson Common Stock
are accepted for exchange pursuant to the Exchange Offer and, if at the time
notice of such increase is first published, sent or given to holders of Hudson
Common Stock, the Exchange Offer is scheduled to expire at any time earlier than
the expiration of a period ending on the tenth business day from and including
the date that such notice is first so published, sent or given, the Exchange
Offer will be extended until the expiration of such period of ten business days.
For purposes of the Exchange Offer, a "business day" means any day other than a
Saturday, Sunday or federal holiday and consists of the time period from 12:01
A.M. through 12:00 midnight, New York City time.


EXCHANGE OF SHARES; EXCHANGE CONSIDERATION

            Upon the terms and subject to the conditions of the Exchange Offer,
the acceptance for exchange and the exchange of the outstanding shares of Hudson
Common Stock validly tendered and not withdrawn will be made as soon as
practicable after the Expiration Date. Subject to applicable rules of the SEC,
TrustCo expressly reserves the right to delay acceptance for exchange or the
exchange of Hudson Common Stock in order to comply with any applicable law.

            For purposes of the Exchange Offer, TrustCo will be deemed to have
accepted for exchange and thereby acquired tendered Hudson Common Stock as, if
and when TrustCo gives oral or written notice to the Exchange Agent of its
acceptance of the tenders of such shares of Hudson Common Stock. Delivery of the
Exchange Consideration in exchange for the Hudson Common Stock pursuant to the
Exchange Offer will be made by the Exchange Agent as soon as practicable after
receipt of such notice. The Exchange Agent will act as agent for tendering
shareholders for the purpose of receiving the Exchange Consideration from
TrustCo and transmitting such Exchange Consideration to tendering shareholders.
Under no circumstances will interest be paid by TrustCo by reason of any delay
in making such exchange.

            If any tendered shares of Hudson Common Stock are not acceptable for
exchange pursuant to the terms and conditions of the Exchange Offer for any
reason, or if certificates are submitted for more shares of Hudson Common Stock
than are tendered, certificates for such un-exchanged Hudson Common Stock will
be returned to the tendering Hudson shareholder by the Exchange Agent as soon as
practicable following consummation or termination of the Exchange Offer.

CASH IN LIEU OF FRACTIONAL SHARES OF TRUSTCO COMMON STOCK


            No certificates representing fractional shares of TrustCo Common
Stock will be issued by TrustCo pursuant to the Exchange Offer. In lieu thereof,
each tendering shareholder who would otherwise be entitled to a fractional share
of TrustCo Common Stock will receive additional cash in an amount equal to the
average closing price of one share of TrustCo Common Stock on Nasdaq over the
20-day period ending 5 days before the closing of the Exchange Offer multiplied
by the fractional share of TrustCo Common Stock that such tendering shareholder
was otherwise entitled to receive.

WITHDRAWAL RIGHTS

            Shares of Hudson Common Stock tendered pursuant to the Exchange
Offer may be withdrawn at any time after ___________, 2000 and prior to the
expiration of the Exchange Offer and the acceptance of Hudson Common Stock for
exchange pursuant to the Exchange Offer.

            For a withdrawal to be effective, a written, telegraphic, telex or
facsimile transmission notice of withdrawal must be timely received by the
Exchange Agent at its address set forth on the back cover of this Prospectus and
must specify the name of the person having tendered the shares of Hudson Common
Stock to be withdrawn, the number of shares of Hudson Common Stock to be
withdrawn and the name of the registered holder, if different from that of the
person who tendered such shares of Hudson Common Stock.

            The signature(s) on the notice of withdrawal must be guaranteed by a
firm which is a member of a registered national securities exchange or of the
National Association of Securities Dealers, Inc. (the "NASD") or by a commercial
bank or trust company having an office or correspondent in the United States
(collectively, "Eligible Institutions") unless such shares of Hudson Common
Stock have been tendered for the account of any Eligible Institution. If
certificates have been delivered or otherwise identified to the Exchange Agent,
the name of the registered holder and the serial numbers of the particular
certificates evidencing the shares of Hudson Common Stock withdrawn must also be
furnished to the Exchange Agent as aforesaid prior to the physical release of
such certificates. All questions as to the form and validity (including time of
receipt) of notices of withdrawal will be determined by TrustCo in its sole
discretion, whose determination will be final and binding. Neither TrustCo, the
Exchange Agent nor any other person will be under any duty to give notification
of any defects or irregularities in any notice of withdrawal or will incur any
liability for failure to give any such notification. Any shares of Hudson Common
Stock properly withdrawn will be deemed not to have been validly tendered for
purposes of the Exchange Offer. However, withdrawn shares of Hudson Common Stock
may be re-tendered by following one of the procedures described under "THE
EXCHANGE OFFER -- Procedure for Tendering Shares" at any time prior to the
Expiration Date.

PROCEDURE FOR TENDERING SHARES

            To tender shares of Hudson Common Stock pursuant to the Exchange
Offer, a properly completed and duly executed Letter of Transmittal (or
facsimile thereof), together with the certificates representing the tendered
Hudson Common Stock and any other required documents, must be transmitted to and
received by the Exchange Agent at its address set forth on the back cover of
this Prospectus. THE METHOD OF DELIVERY OF ALL REQUIRED DOCUMENTS IS AT THE
OPTION AND RISK OF THE TENDERING SHAREHOLDER. IF DELIVERY IS BY MAIL, REGISTERED
MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.

            Signatures on all Letters of Transmittal must be guaranteed by an
Eligible Institution in cases where shares of Hudson Common Stock are tendered
by a registered holder of Hudson Common Stock who has completed either the box
entitled "Special Payment Instructions" or the box entitled "Special Delivery
Instructions" on the Letter of Transmittal. If the certificates are registered
in the name of a person other than the signer of the Letter of Transmittal, or
if certificates for un-exchanged shares of Hudson Common Stock are to be issued
to a person other than the registered holder(s), the certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name or names of the registered owner or owners appear on the
certificates, with the signature(s) on the certificates or stock powers
guaranteed as aforesaid.

            By executing a Letter of Transmittal as set forth above, the
tendering shareholder irrevocably appoints designees of TrustCo as such
shareholder's proxies, each with full power of substitution, to the full extent
of such shareholder's rights with respect to the shares of Hudson Common Stock
tendered by such shareholder and accepted for exchange by TrustCo and with
respect to any and all other shares of


                                       35
<PAGE>

Hudson Common Stock and other securities issued or issuable in respect of the
Hudson Common Stock on or after ____________________, 2000. Such appointment
will be effective when, and only to the extent that, TrustCo exchanges the
Exchange Consideration for Hudson Common Stock tendered by such shareholder. To
such extent, all prior proxies appointed by such shareholder will be revoked.
Such designees will be empowered, among other things, to vote such shares of
Hudson Common Stock as they in their sole discretion deem proper at any annual,
special or adjourned meeting of Hudson's shareholders or otherwise. TrustCo
reserves the right to require that, in order for shares of Hudson Common Stock
to be deemed validly tendered, immediately upon TrustCo's exchange of such
Hudson Common Stock TrustCo must be able to exercise full voting rights with
respect to such shares of Hudson Common Stock.

            If a shareholder desires to tender shares of Hudson Common Stock
pursuant to the Exchange Offer and such shareholder's certificates are not
immediately available or time will not permit his Letter of Transmittal, stock
certificates and any other required documents to reach the Exchange Agent prior
to the Expiration Date, his tender may nevertheless be effected if all the
following conditions are met: (i) such tender is made by or through an Eligible
Institution; (ii) a properly completed and duly executed Notice of Guaranteed
Delivery substantially in the form provided by TrustCo herewith is received by
the Exchange Agent as provided below on or prior to the Expiration Date; and
(iii) the certificates for all tendered shares of Hudson Common Stock, together
with a properly completed and duly executed Letter of Transmittal (or facsimile
thereof) and any other documents required by the Letter of Transmittal, are
received by the Exchange Agent within five business days after the date of
execution of such Notice of Guaranteed Delivery.

            The Notice of Guaranteed Delivery may be delivered by hand to the
Exchange Agent or transmitted by telegram, telex, facsimile transmission or mail
to the Exchange Agent and must include a signature guaranteed by an Eligible
Institution in the form set forth in such Notice.

            In any event, the exchange of Exchange Consideration for Hudson
Common Stock tendered and accepted for exchange pursuant to the Exchange Offer
will be made only after timely receipt by the Exchange Agent of certificates
therefor properly completed, duly executed Letter(s) of Transmittal and any
other required documents.

            To avoid backup federal income tax withholding with respect to the
Exchange Consideration received by a shareholder pursuant to the Exchange Offer,
the shareholder must provide the Exchange Agent with his correct taxpayer
identification number or certify that he or she is not subject to backup Federal
income tax withholding by completing the Substitute Form W-9 included in the
Letter of Transmittal.


            All questions as to the validity, form, eligibility (including time
of receipt) and acceptance of any tender of Hudson Common Stock will be
determined by TrustCo in its sole discretion, whose determination will be final
and binding. TrustCo reserves the absolute right to reject any or all tenders
determined by it not to be in proper form or the acceptance of or exchange for
which may, in the opinion of TrustCo's counsel, be unlawful. TrustCo also
reserves the absolute right to waive on or prior to the Expiration Date any of
the conditions of the Exchange Offer which it is legally permitted to waive
(other than the Regulatory Approval Condition, the TrustCo Stockholder Approval
Condition and the effectiveness of the Registration Statement) or any defect or
irregularity in the tender of any shares of Hudson Common Stock. No tender of
Hudson Common Stock will be deemed to have been validly made until all defects
and irregularities have been cured or waived. TrustCo's interpretation of the
terms and conditions of the Exchange Offer (including the Letter of Transmittal
and instructions thereto) will be final and binding. Neither TrustCo, the
Exchange Agent nor any other person will be under any duty to give notification
of any defects or irregularities in the tender of any shares of Hudson Common
Stock or will incur any liability for failure to give any such notification.



                                       36

            A tender of Hudson Common Stock pursuant to the procedures described
above will constitute a binding agreement between the tendering shareholder and
TrustCo upon the terms and subject to the conditions of the Exchange Offer.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES


            In the opinion of Lewis, Rice & Fingersh, L.C., counsel to TrustCo,
exchanges of Hudson Common Stock for TrustCo Common Stock pursuant to the
Exchange Offer and the TrustCo-Hudson Merger should be treated for federal
income tax purposes as a reorganization within the meaning of ss.368 of the
Code. In such event, no gain or loss will be recognized by holders of shares of
Hudson Common Stock, except as described below under "Tax Consequences to Hudson
Shareholders if the Exchange Offer and the TrustCo-Hudson Merger Qualify as a
Reorganization." This opinion is based on the view of Lewis, Rice & Fingersh,
L.C. that the Exchange Offer and the TrustCo-Hudson Merger should be treated as
a single transaction and on certain assumptions and representations, including
that: (i) each Hudson shareholder holds his or her shares of Hudson Common Stock
and will hold the TrustCo Common Stock to be received as a capital asset within
the meaning of ss.1221 of the Code; (ii) the continuity of shareholder interest
requirement applicable to corporate reorganizations (which requires the receipt
of an equity interest in TrustCo by holders owning a significant percentage of
the shares of Hudson Common Stock prior to the consummation of the Exchange
Offer) will be satisfied; (iii) TrustCo will continue Hudson's historic business
or will use a significant portion of Hudson's historic business assets in a
business; (iv) the Exchange Offer and the TrustCo-Hudson Merger will be
consummated as contemplated by this Prospectus; and (vi) there are valid
business reasons for undertaking the Exchange Offer and the TrustCo-Hudson
Merger.


            In rendering their opinion, Lewis, Rice & Fingersh, L.C. have
further assumed that: (i) upon consummation of the Exchange Offer, there will be
no significant contingencies preventing the prompt consummation of the
TrustCo-Hudson Merger; (ii) upon consummation of the Exchange Offer, TrustCo
will not have waived any of the conditions relating to its obligation to
consummate the Exchange Offer in a manner that could prevent a prompt
consummation of the TrustCo-Hudson Merger; and (iii) the TrustCo-Hudson Merger
will in fact be consummated promptly after the consummation of the Exchange
Offer. A significant delay in the consummation of the TrustCo-Hudson Merger
would substantially increase the risk that the Exchange Offer will not qualify
as part of a reorganization within the meaning of ss.368(a)(1)(A) of the Code.
The consequences of a failure to so qualify are discussed below under "Tax
Consequences if the Exchange Offer and the TrustCo-Hudson Merger Do Not Qualify
as a Reorganization."

            In deciding whether two steps are part of a single transaction
qualifying as a reorganization, courts have applied three tests: (i) the binding
commitment test, which requires a binding commitment at the time of the first
step to complete the second step; (ii) the interdependence test which requires
that two steps be so interdependent that the first step would have been
fruitless without the second; and (iii) the end result test which requires that
the steps be pre-arranged parts of a single transaction. Because there is a lack
of uniformity in applying these tests, it is difficult to predict with certainty
whether the Internal Revenue Service (the "IRS") or a court would amalgamate two
steps into a single transaction for federal income tax purposes. However, in the
opinion of Lewis, Rice & Fingersh, L.C., the Exchange Offer and the
TrustCo-Hudson Merger should be treated as part of a single transaction.

            The following discussion summarizes the material federal income tax
consequences of the Exchange Offer to the shareholders of Hudson. This summary
does not address all aspects of federal taxation that may be relevant to
particular Hudson shareholders, nor does this summary address the effect of any
applicable foreign, state, local or other tax laws. This discussion may not
apply to certain classes of taxpayers, including, without limitation, insurance
companies, tax-exempt organizations, financial institutions, dealers in
securities, foreign persons, persons who acquired shares of Hudson Common Stock


                                       37
<PAGE>

pursuant to an exercise of employee stock options or rights or otherwise as
compensation and persons who hold shares of Hudson Common Stock as part of a
straddle or conversion transaction.

            This discussion is based upon the opinion of Lewis, Rice & Fingersh,
L.C. and the existing provisions of the Code, currently applicable regulations
promulgated under the Code, current published administrative positions of the
IRS such as revenue rulings and revenue procedures, and existing judicial
decisions, all of which are subject to change either prospectively or
retroactively. Any change in such authorities may adversely affect the
discussion herein.

            The opinion of Lewis, Rice & Fingersh, L.C. is based, among other
things, on the assumptions listed above, which assumptions have been made with
the consent of TrustCo, and the written representations of TrustCo. TrustCo will
not request a ruling from the IRS with respect to the federal income tax
consequences of the Exchange Offer and the TrustCo-Hudson Merger. An opinion of
counsel is not binding on the IRS, and the IRS is not precluded from taking
contrary positions.

            HUDSON SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS
TO THE PRECISE FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES OF THE
EXCHANGE OFFER.

            TAX CONSEQUENCES TO HUDSON SHAREHOLDERS IF THE EXCHANGE OFFER AND
THE TRUSTCO-HUDSON MERGER QUALIFY AS A REORGANIZATION

            In order for the Exchange Offer and the TrustCo-Hudson Merger to
qualify as a reorganization under the Code, it is necessary that Exchange Offer
and the TrustCo-Hudson Merger be viewed as a single transaction.


            TrustCo has represented that it will not undertake the Exchange
Offer unless it can also effect the TrustCo-Hudson Merger and, consequently, has
conditioned its obligation to accept shares of Hudson Common Stock under the
Exchange Offer by requiring the elimination of various impediments to
consummation of the TrustCo-Hudson Merger. See "THE EXCHANGE OFFER--Certain
Conditions of the Exchange Offer--Removal of Impediments Condition." Thus,
TrustCo views the Exchange Offer and the TrustCo-Hudson Merger as interdependent
parts of a single transaction. For federal income tax purposes, the IRS should
treat the Exchange Offer and the TrustCo-Hudson Merger as interrelated steps
which do not have economic significance independent of each other. Accordingly,
it is anticipated that the Exchange Offer and the TrustCo-Hudson Merger together
should qualify as a reorganization for federal income tax purposes and a Hudson
shareholder who receives the Exchange Consideration generally will realize gain
equal to the excess, if any, of: (1) the fair market value of the TrustCo Common
Stock and the amount of cash received over (2) such shareholder's adjusted tax
basis in the Hudson Common Stock exchanged therefor, but will recognize gain
(but not loss) only up to the extent of cash received (excluding cash received
in lieu of fractional shares, which will be taxed as described below).

             Such recognized gain will constitute capital gain, unless as
discussed below, the receipt of the cash has the effect of a distribution of a
dividend for federal income tax purposes, in which case such recognized gain
will be treated as ordinary dividend income to the extent of such shareholder's
ratable share of TrustCo's accumulated earnings and profits. Any capital gain
recognized will constitute long-term capital gain if the Hudson shareholder's
holding period for the Hudson Common Stock exchanged is greater than one year as
of the date of the exchange.

            The aggregate tax basis of the TrustCo Common Stock received by a
Hudson shareholder, including for this purpose any fractional share of TrustCo
Common Stock for which cash is received, in exchange for Hudson Common Stock
pursuant to the Exchange Offer and the TrustCo-Hudson Merger generally will
equal that shareholder's aggregate tax basis of his Hudson Common



                                       38
<PAGE>


Stock surrendered in exchange therefor, decreased by the amount of the cash
portion of the Exchange Consideration received (excluding any cash received in
lieu of fractional shares) and increased by the amount of gain recognized. The
holding period of such shares of TrustCo Common Stock will include the holding
period of the Hudson Common Stock surrendered in exchange therefor, provided
that the such shares of Hudson Common Stock are held as capital assets at the
time of the Exchange Offer and TrustCo-Hudson Merger.

            In general, the determination of whether the gain recognized by a
Hudson shareholder will be treated as capital gain or a dividend distribution
will depend upon whether and to what extent the exchange reduced the Hudson
shareholder's deemed percentage stock ownership interest in TrustCo. For
purposes of this determination, a Hudson shareholder will be treated as if such
shareholder first exchanged all of such shareholder's Hudson Common Stock solely
for TrustCo Common Stock and TrustCo immediately thereafter redeemed a portion
of such TrustCo Common Stock in exchange for the cash portion of the Exchange
Consideration that the Hudson shareholder actually received. The gain recognized
in the exchange followed by a deemed redemption will be treated as capital gain
if, with respect to the Hudson shareholder, the deemed redemption is (i)
"substantially disproportionate" or (ii) "not essentially equivalent to a
dividend."

            In general, the determination of whether the deemed redemption will
be "substantially disproportionate" requires a comparison of (i) the percentage
of the outstanding voting stock of TrustCo that such Hudson shareholder is
deemed actually and constructively to have owned immediately before the deemed
redemption by TrustCo and (ii) the percentage of the outstanding voting stock of
TrustCo actually and constructively owned by such shareholder immediately after
the deemed redemption by TrustCo. Generally, the deemed redemption will be
substantially disproportionate with respect to a Hudson shareholder if the
percentage described in (ii) above is less than 80 percent of the percentage
described in (i) above. Whether the deemed redemption is "not essentially
equivalent to a dividend" with respect to a Hudson shareholder will depend on
the shareholder's particular circumstances. In order for the deemed redemption
to be "not essentially equivalent to a dividend," the deemed redemption must
result in a "meaningful reduction" in such Hudson shareholder's deemed
percentage stock ownership of TrustCo Common Stock. The IRS has ruled that a
minority shareholder in a publicly traded corporation whose relative stock
interest is minimal and that exercises no control with respect to corporate
affairs is considered to have a "meaningful reduction" generally if such
shareholder has some reduction in such shareholder's percentage stock ownership.

            In applying the foregoing tests, a shareholder may be deemed to own
stock that is owned by other persons, such as a family member, a trust, or other
entities, in addition to stock actually owned. Because the constructive
ownership rules are complex, each Hudson shareholder should consult its own tax
advisor as to the applicability of these rules.

            Cash received in lieu of a fractional shares of TrustCo Common Stock
will be treated as received in redemption of such fractional share interest, and
a Hudson shareholder will recognize gain or loss measured by the difference
between the amount of cash received and the portion of the basis of the TrustCo
Common Stock allocable to such fractional interest. Such gain or loss generally
will constitute capital gain or loss and will be long-term capital gain or loss
if the Hudson shareholder's holding period in the Hudson Common Stock exchanged
was greater than one year as of the date of the exchange.


            TAX CONSEQUENCES TO HUDSON SHAREHOLDERS IF THE EXCHANGE OFFER AND
THE TRUSTCO-HUDSON MERGER DO NOT QUALIFY AS A REORGANIZATION

            If the TrustCo-Hudson Merger is not consummated or is consummated in
a way that causes the Exchange Offer and the TrustCo-Hudson Merger not to be a
"reorganization," or if the TrustCo-Hudson


                                       39
<PAGE>

Merger is consummated but the Exchange Offer is treated for federal income tax
purposes as a separate transaction, or if the Exchange Offer and the
TrustCo-Hudson Merger together are determined not to qualify as a reorganization
as described above, exchanges pursuant to the Exchange Offer will be taxable
transactions for federal income tax purposes. In that event, each exchanging
shareholder of Hudson Common Stock will recognize gain or loss for federal
income tax purposes measured by the difference between such shareholder's basis
in the Hudson Common Stock exchanged and the amount of cash plus the fair market
value of the TrustCo Common Stock received by such shareholder in the Exchange
Offer. Such gain or loss will be capital gain or loss if the shares of Hudson
Common Stock were held as a capital asset and will be long-term gain or loss if
such Hudson Common Stock had been held for more than one year at the time of the
exchange.

            Exchanges pursuant to the TrustCo-Hudson Merger may likewise be
taxable transactions if the Exchange Offer is treated as a separate taxable
transaction. However, even if the Exchange Offer were a taxable transaction, the
TrustCo-Hudson Merger itself might be considered a reorganization. In that
event, a shareholder of Hudson Common Stock receiving TrustCo Common Stock and
cash would be subject to the federal income tax rules concerning reorganizations
discussed above with respect to the TrustCo Common Stock and cash received in
the TrustCo-Hudson Merger (but not with respect to any TrustCo Common Stock and
cash received by such shareholder in the Exchange Offer).

            If the TrustCo-Hudson Merger does not qualify as a reorganization
for tax purposes, the TrustCo-Hudson Merger might result in adverse tax
consequences to TrustCo.

EFFECT OF EXCHANGE OFFER ON MARKET FOR SHARES


            As of August 4, 2000, according to Hudson's Quarterly Report on Form
10-Q filed on August 10, 2000, there were 15,310,560 shares of Hudson Common
Stock outstanding.


            The exchange of Hudson Common Stock pursuant to the Exchange Offer
will reduce the number of shares of Hudson Common Stock that might otherwise
trade publicly and the number of holders of Hudson Common Stock and, pending
consummation of the TrustCo-Hudson Merger, could adversely affect the liquidity
and market value of the remaining Hudson Common Stock held by the public.

            Hudson Common Stock is quoted in the over-the-counter market on
Nasdaq. If the Exchange Offer is consummated, the extent of the public market
for the remaining shares of Hudson Common Stock, and the availability of price
quotations, will depend upon the number of holders, the aggregate market value
of the Hudson Common Stock remaining, the interest of securities firms in
maintaining a market in the Hudson Common Stock and other factors.

RESALE OF TRUSTCO COMMON STOCK

            The TrustCo Common Stock to be issued pursuant to the Exchange Offer
will be freely transferable under the 1933 Act except for shares issued to any
Hudson shareholder who may be deemed to be an "affiliate" of Hudson for purposes
of Rule 145 under the 1933 Act. Under Rule 145, such "affiliates" may not sell
their TrustCo Common Stock acquired in connection with the Exchange Offer except
pursuant to an effective registration statement under the 1933 Act covering such
shares or in compliance with Rule 145 promulgated under the 1933 Act or another
applicable exemption from the registration requirements of the 1933 Act. This
Prospectus does not cover resales of shares of TrustCo Common Stock received by
any person who may be deemed to be an "affiliate" of Hudson. Persons who may be
deemed to be "affiliates" of Hudson generally include individuals who, or
entities that, control, are controlled by or are under common control with
Hudson, and may include certain officers and directors of Hudson as well as
principal shareholders of Hudson.

CERTAIN LEGAL MATTERS

            GENERAL

            Except as set forth below, based upon an examination of publicly
available information filed by Hudson with the SEC and other publicly available
information with respect to Hudson, TrustCo is not aware of any license or
regulatory permit which appears to be material to the business of Hudson and
which is likely to be adversely affected by TrustCo's acquisition of Hudson
Common Stock pursuant to the Exchange Offer or, except as disclosed below, of
any approval or other action by any state, federal or foreign government or
governmental agency that would be required prior to the acquisition of Hudson
Common Stock pursuant to the Exchange Offer. TrustCo presently intends to take
such actions with respect to any approvals as will enable it to acquire the
Hudson Common Stock as expeditiously as possible. In this regard, TrustCo
expressly reserves the right to challenge the validity and applicability of any
state, foreign or other statutes or regulations purporting to require approval
of the commencement or consummation of the Exchange Offer and the TrustCo-Hudson
Merger.

            There can be no assurance that any license, permit, approval or
other action, if needed, would be obtained and, if obtained, there can be no
assurance as to the date of any such license, permit or approval or the absence
of any litigation challenging any such license, permit or approval. Similarly,
there can be no assurance that adverse consequences might not result to Hudson
or to its business in the event of adverse regulatory action or inaction.
TrustCo's obligation under the Exchange Offer to accept for exchange and
exchange Hudson Common Stock is subject to satisfaction of the Regulatory
Approval Condition as well as other conditions which could be triggered by an
adverse regulatory development. See "THE EXCHANGE OFFER -- General" and "--
Certain Conditions of the Exchange Offer."

            FEDERAL REGULATORY MATTERS

            The acquisition of Hudson Common Stock pursuant to the Exchange
Offer (the "Acquisition") and the consummation of the TrustCo-Hudson Merger are
subject to the prior approval by the Federal Reserve Board pursuant to the Bank
Holding Company Act of 1956, as amended (the B.H.C.A.) and the New York State
Banking Department (the "NYBD").


            In determining whether to approve the Acquisition and the
TrustCo-Hudson Merger, the Federal Reserve Board and the NYBD will consider,
among other things: (i) competitive factors; (ii) the financial and managerial
resources and future prospects of TrustCo and Hudson; (iii) the convenience and
needs of the community served by TrustCo and Hudson; and (iv) supervisory
factors. These factors are discussed herein. It is anticipated that TrustCo's
applications to the Federal Reserve Board and the NYBD for approval of the
Exchange Offer and the TrustCo-Hudson Merger will be filed on or about
__________, 2000.


            Following approval by the Federal Reserve Board, the Acquisition may
not be consummated for 30 days after such approval, during which time the United
States Department of Justice (the "D.O.J.") may challenge the acquisition of
Hudson Common Stock pursuant to the Exchange Offer on antitrust grounds and seek
the divestiture of certain assets and liabilities. With the approval of the
Federal Reserve Board and the D.O.J., the waiting period may be reduced to no
less than 15 days.

            The Federal Reserve Board is prohibited from approving any
transaction under the applicable statutes which: (i) would result in a monopoly
or which would be in furtherance of any combination or conspiracy to monopolize
or to attempt to monopolize the business of banking in any part of the United
States; or (ii) may have the effect in any section of the United States of
substantially lessening competition, or tending to create a monopoly, or
resulting in a restraint of trade; unless in each case the Federal Reserve Board
finds that the anti-competitive effects of the transaction are clearly
outweighed in the public interest by the probable effect of the transaction in
meeting the convenience and needs of the communities to be served.


                                       41
<PAGE>

            In reviewing a transaction under the applicable statutes, the
Federal Reserve Board will also consider the financial and managerial resources
of the companies and their subsidiary banks and the convenience and needs of the
communities to be served. As part of, or in addition to, consideration of the
above factors, it is anticipated that the Federal Reserve Board will consider
the regulatory status of TrustCo and Hudson and the overall capital and safety
and soundness standards established by the Federal Deposit Insurance Corporation
Improvement Act of 1991 and the regulations promulgated thereunder.

            Under the Community Reinvestment Act of 1977, as amended (the
"C.R.A."), the Federal Reserve Board must also take into account the record of
performance of each of TrustCo and Hudson in meeting the credit needs of the
entire community, including low and moderate income neighborhoods, served by
each company. As of the date of this Prospectus, the depository institution
subsidiaries of TrustCo and Hudson received C.R.A. ratings of satisfactory, and
satisfactory in their most recent C.R.A. examinations.

            The B.H.C.A. and the Federal Reserve Board regulations also require
publication of notice of, and the opportunity for public comment on, the
application submitted by TrustCo for approval of the Acquisition and authorize
the Federal Reserve Board to hold a public hearing in connection therewith if
the Federal Reserve Board determines that such a hearing would be appropriate.
Any such hearing or comments provided by third parties could prolong the period
during which the application is subject to review by the Federal Reserve Board.

            As noted above, the Acquisition may not be consummated until 30 days
after Federal Reserve Board approval, during which time the D.O.J. may challenge
the Acquisition on antitrust grounds and seek the divestiture of certain assets
and liabilities. With the approval of the Federal Reserve Board and the D.O.J.,
the waiting period may be reduced to no less than 15 days. The commencement of
an antitrust action by the D.O.J. would stay the effectiveness of Federal
Reserve Board approval of the Acquisition unless a court specifically orders
otherwise. In reviewing the Acquisition, the D.O.J. could analyze the effect of
the Acquisition on competition differently than the Federal Reserve Board and,
thus, it is possible that the D.O.J. could reach a different conclusion than the
Federal Reserve Board regarding the competitive effects of the Acquisition.
Failure of the D.O.J. to object to the Acquisition may not prevent the filing of
antitrust actions by private persons or state attorneys general.

            In general, the Federal Reserve Board and the D.O.J. will examine
the impact of the Acquisition on competition in various product and geographic
markets, including competition for deposits and loans, especially loans to small
and middle market businesses.

            ANTICIPATED APPROVALS

            While TrustCo expects to receive the approvals from the Federal
Reserve Board and the NYBD and other relevant agencies required to consummate
the Acquisition, TrustCo cannot predict when, or give any assurance that, such
approvals will be received. It is anticipated that, in any event, the approval
process (including the mandatory waiting periods) could take four months from
the date the applications are filed. Any such approvals may be issued subject to
prior compliance with material conditions, which conditions might be
unacceptable to TrustCo and would entitle TrustCo to terminate the Exchange
Offer. In any event, the receipt of all such regulatory approvals and the
expiration of all waiting periods is a non-waivable condition to the Exchange
Offer.

CERTAIN CONDITIONS OF THE EXCHANGE OFFER

            TrustCo's obligation to accept Hudson Common Stock pursuant to the
Exchange Offer is subject to a number of conditions, which are described below.
TrustCo reserves the absolute right to waive on or before the Expiration Date
any of the conditions of the Exchange Offer other than the conditions regarding
regulatory approval, the TrustCo stockholder approval and the effectiveness of
the Registration Statement.


                                       42

            MINIMUM TENDER CONDITION


            The Exchange Offer is conditioned upon there being validly tendered
and not withdrawn prior to the Expiration Date a number of shares of Hudson
Common Stock which, together with the shares of Hudson Common Stock beneficially
owned by TrustCo and its affiliates for their own respective accounts, would
represent at least a majority of the Hudson Common Stock outstanding on a fully
diluted basis (i.e., as though all options or other securities convertible into
or exercisable for shares of Hudson Common Stock had been so converted,
exercised or exchanged) on the date shares of Hudson Common Stock are accepted
by TrustCo pursuant to the Exchange Offer (the "Minimum Tender Condition").
According to the Hudson Proxy Statement, there were 15,310,560 shares of Hudson
Common Stock outstanding on June 20, 2000 and 2,499,525 shares of Hudson Common
Stock in the aggregate reserved for issuance pursuant to Hudson's Stock Option
and Incentive Plan and Hudson's Recognition and Retention Plan. Based on the
foregoing, TrustCo believes that the Minimum Tender Condition would have been
satisfied on June 20, 2000 if, in addition to the 108,500 shares of Hudson
Common Stock currently owned beneficially by TrustCo and its affiliates for
their own respective accounts, at least an aggregate of 7,546,781 shares of
Hudson Common Stock outstanding on June 20, 2000, in addition to shares of
Hudson Common Stock in an amount at least equal to 50.1% of any outstanding
options to acquire Hudson Common Stock, had been validly tendered pursuant to
the Exchange Offer and not withdrawn. TrustCo reserves the right (but is not
obligated), subject to the rules and regulations of the SEC, to waive or amend
on or before the Expiration Date the Minimum Tender Condition and to purchase
fewer than such number of shares of Hudson Common Stock as would satisfy the
Minimum Tender Condition pursuant to the Exchange Offer.


            REGULATORY APPROVAL CONDITION


            The Exchange Offer and the TrustCo-Hudson Merger are subject to the
receipt of all regulatory approvals sought by TrustCo in connection with the
transactions contemplated by the Exchange Offer without the imposition of any
material condition unacceptable to TrustCo, the expiration of all required
waiting periods, and the compliance by TrustCo with any terms or conditions of
such approvals (the "Regulatory Approval Condition"). See "THE EXCHANGE
OFFER--Certain Legal Matters." While TrustCo expects to receive the requisite
governmental approvals, TrustCo cannot predict when, or give any assurance that,
such approvals will be received. In any event, the Regulatory Approval Condition
is a non-waivable condition to the Exchange Offer.


            REMOVAL OF IMPEDIMENTS CONDITION


            Hudson's Certificate of Incorporation (the "Hudson Certificate")
provides that certain business combinations with an interested stockholder
require the affirmative vote of the holders of at least 80% of the voting power
of the outstanding shares of stock of Hudson entitled to vote in the election of
directors. Generally, an interested stockholder is any person, other than Hudson
or any subsidiary of Hudson, that is the beneficial owner, directly or
indirectly, of more than 10% of the voting power of the outstanding voting stock
of Hudson. The business combination provisions relating to interested
stockholders also apply to affiliates of interested stockholders. Business
combinations subject to the 80% stockholder approval requirement include, among
other things, any merger or consolidation of Hudson or any subsidiary of Hudson
with the interested stockholder or an affiliate of the interested stockholder. A
business combination with an interested stockholder may avoid the 80%
stockholder approval requirement, needing only an affirmative vote of a majority
of the voting power of the outstanding shares of stock of Hudson entitled to
vote in the election of directors, if the business combination has been approved
by a majority of the disinterested directors of Hudson, the fair market value of
the consideration received per share by the holders of Hudson Common Stock
equals or exceeds the higher of certain fair price determinations, the
interested stockholder and its affiliates refrain from engaging in certain
self-dealing transactions with Hudson prior to consummation of the business
combination, and a proxy or information statement describing the proposed
business combination and complying with the



                                       43
<PAGE>

requirements of the 1934 Act has been mailed to stockholders of Hudson at least
30 days prior to the consummation of such business combination. Hudson's
Certificate also provides that, with certain exceptions, a beneficial owner of
more than 10% of the voting stock of Hudson is prohibited from voting more than
10% of the stock of Hudson (the "10% Limit").


            The Delaware General Corporation Law (the "DGCL") contains a statute
designed to provide Delaware corporations with protection against certain
takeover attempts. The statute, which is codified in Section 203 of the DGCL
("Section 203"), among other things, prohibits Hudson (a Delaware corporation)
from engaging in certain business combinations (including a merger) with a
person who is the beneficial owner of 15% or more of Hudson's outstanding voting
stock (an "Interested Stockholder") during the three-year period following the
date such person became an Interested Stockholder. This restriction does not
apply if: (i) before such person became an Interested Stockholder, the board of
directors approved the transaction in which the Interested Stockholder becomes
an Interested Stockholder or approved the business combination; or (ii) upon
consummation of the transaction which resulted in the stockholder becoming an
Interested Stockholder, the Interested Stockholder owned at least 85% of the
voting stock of Hudson outstanding at the time the transaction commenced,
excluding for purposes of determining the number of shares outstanding, those
shares owned by (a) persons who are directors and also officers and (b) employee
stock plans in which employee participants do not have the right to determine
confidentially whether shares held subject to the plan will be tendered in a
tender or exchange offer; or (iii) on or subsequent to such date, the business
combination is approved by the board of directors and authorized at an annual or
special meeting of stockholders, and not by written consent, by the affirmative
vote of at least two-thirds of the outstanding voting stock which is not owned
by the Interested Stockholder. Section 203 provides that a Delaware corporation
may exempt itself from the requirements of the statute by adopting an amendment
to the corporation's certificate of incorporation. Hudson's Certificate does not
exempt Hudson from the requirements of Section 203. A copy of Section 203 is
attached hereto as Appendix B.

            The New York charter of Hudson River Bank & Trust Company, the
thrift subsidiary of Hudson, contains a provision which currently prevents any
person from acquiring, directly or indirectly, more than ten percent of any
class of stock of Hudson River Bank & Trust Company. Because Hudson River Bank &
Trust Company is owned and controlled by Hudson, the acquisition of Hudson
Common Stock pursuant to the Exchange Offer may be deemed to be an indirect
acquisition of the equity securities of Hudson River Bank & Trust Company which,
accordingly, may result in a violation of the New York charter of Hudson River
Bank & Trust Company. This ownership limitation is being maintained on a
permissive basis by Hudson River Bank & Trust Company and may be lawfully
removed by amendment to its charter. The charter of Hudson River Bank & Trust
Company could be amended through the adoption of appropriate resolutions by the
board of directors of Hudson River Bank & Trust Company -- who are substantially
the same individuals as the directors of Hudson -- which resolutions would
thereafter be approved by the Hudson Board of Directors (the "Hudson Board")
acting on its behalf as the sole stockholder of Hudson River Bank & Trust
Company.

            All of the above are impediments to the consummation of the
TrustCo-Hudson Merger. The Exchange Offer is subject to the condition (the
"Removal of Impediments Condition") that TrustCo is not required to exchange
shares of Hudson Common Stock and may terminate, amend or extend the Exchange
Offer on or prior to the Expiration Date, unless the above impediments are
removed. This can be satisfied in one of two ways; either: (i) the Hudson Board
approves the Exchange Offer and the Hudson Board and Hudson shareholders (by a
majority vote of the outstanding shares of Hudson stock) approve the
TrustCo-Hudson Merger; or (ii) TrustCo being satisfied, in its reasonable
discretion, that Section 203 and the anti-takeover provisions of Hudson's
Certificate and the charter of Hudson River Bank & Trust Company are invalid or
are not applicable to the transactions contemplated by the Exchange Offer and
the TrustCo-Hudson Merger. The consideration offered pursuant to the Exchange
Offer meets the fair price requirements of the business combination provisions
of Hudson's Certificate and, except for the required approval of Hudson's
directors and



                                       44
<PAGE>


shareholders, satisfaction of the other conditions would be within TrustCo's
control. Accordingly, the approval of the Exchange Offer and the TrustCo-Hudson
Merger by the Hudson Board (other than any director nominated by TrustCo and
thereafter elected to the Hudson Board) would obviate the 80% vote requirement
of Hudson's Certificate and also make Section 203 inapplicable to the
transaction. As part of its approval of the TrustCo-Hudson Merger, the Hudson
Board would also have to: (a) make appropriate arrangements for amendment to the
charter of Hudson River Bank & Trust Company to eliminate the 10% or greater
ownership prohibition contained therein; and (b) call a meeting of shareholders
of Hudson to approve the TrustCo-Hudson Merger.


            The exact timing and details of the closing of the TrustCo-Hudson
Merger between TrustCo and Hudson following the Exchange Offer will necessarily
depend upon a variety of factors, including the means and methods employed by
the Hudson Board in approving, and causing to be held a meeting of Hudson
shareholders for the purpose of approving, the TrustCo-Hudson Merger. Although
TrustCo intends to propose and to seek consummation of the TrustCo-Hudson Merger
as soon as reasonably practicable following the Exchange Offer, no assurances
can be given that the consummation of the Exchange Offer may not be delayed due
to the timing of the Hudson Board and shareholder approvals.

            TRUSTCO STOCKHOLDER APPROVAL CONDITION


            The Exchange Offer is conditioned, among other things, upon the
approval of the issuance of shares of TrustCo Common Stock pursuant to the
Exchange Offer by the holders of a majority of the outstanding shares of TrustCo
Common Stock if required under the rules of the Nasdaq Stock Market. Pursuant to
the rules of the Nasdaq Stock Market, if the number of shares of TrustCo Common
Stock to be issued in the Exchange Offer and the TrustCo-Hudson Merger will
exceed 20% of the number of outstanding shares prior to such issuance, the
issuance must be approved by TrustCo's stockholders. While TrustCo does not
currently anticipate that the number of shares of TrustCo Common Stock to be
issued in the Exchange Offer and the TrustCo-Hudson Merger will exceed the 20%
of the currently outstanding numbers of shares, changes in the price of TrustCo
Common Stock or a determination that the TrustCo Common Stock is to be issued in
TrustCo's proposed acquisition of Cohoes should be aggregated with the shares of
TrustCo Common Stock to be issued in the Exchange Offer and the TrustCo-Hudson
Merger may result in a requirement under the Nasdaq Stock Market rules that
shareholder approval is required. This TrustCo Stockholder Approval Condition is
a non-waivable condition to the Exchange Offer if the rules of the Nasdaq Stock
Market require such an approval.


            TAX OPINION


            The Exchange Offer is conditioned, among other things, upon the
receipt of an opinion of counsel that the Exchange Offer and the TrustCo-Hudson
Merger qualify as a reorganization under ss.368(a)(1)(A) of the Internal Revenue
Code of 1986, as amended (the "Code"). The law firm of Lewis, Rice & Fingersh,
L.C. has indicated that it will issue such opinion based upon and subject to the
assumptions and other matters set forth in "THE EXCHANGE OFFER-- Material
Federal Income Tax Consequences."


            MATERIAL ADVERSE EFFECT CONDITION


            The Exchange Offer is subject to the condition (the "Material
Adverse Effect Condition") that, since June 30, 1999, there has been no material
adverse change, or any prospective material adverse change, in the financial
condition, business or assets of Hudson. This condition will be deemed satisfied
unless, after June 30, 1999 and prior to the close of business on the Expiration
Date any of the following events occur:


                        (a) there is threatened, instituted or pending any
            action or proceeding before any domestic or foreign court or
            governmental agency or other regulatory or administrative agency or
            commission, including but not limited to any such investigation,
            action or proceeding which was


                                       45
<PAGE>


            in existence on or prior to June 30, 1999: (i) seeking to obtain any
            material damages from Hudson; (ii) seeking to prohibit or restrict
            Hudson's ownership or operation of any material portion of its
            business or assets, or to compel Hudson to dispose of or hold
            separate all or any material portion of Hudson's business or assets;
            (iii) which otherwise is reasonably likely to materially adversely
            affect Hudson or the value of the Hudson Common Stock; (iv) which
            imposes material limitations on the ability of TrustCo effectively
            to acquire or hold or to exercise full rights of ownership of the
            Hudson Common Stock, including, without limitation, the right to
            vote the shares of Hudson Common Stock acquired by it on all matters
            properly presented to the stockholders of Hudson or any material
            condition unacceptable to TrustCo; or (v) which is reasonably likely
            to enjoin, restrain or prohibit, or result in material damages in
            respect of, or which is related to or arises out of, the Exchange
            Offer or the TrustCo-Hudson Merger or the consummation of the
            transactions contemplated hereby; or


                        (b) any change (or any condition, event or development
            involving a prospective change) has occurred or is threatened in the
            business, properties, assets, liabilities, capitalization,
            stockholders' equity, financial condition, results of operations or
            prospects of Hudson (including, without limitation, the disposition
            of assets) which, in the reasonable judgment of TrustCo, is or may
            be materially adverse to Hudson or to the value of the Hudson Common
            Stock, or TrustCo becomes aware of any fact (including, but not
            limited to, any such change, condition, event or development) which,
            in the reasonable judgment of TrustCo, has or may have materially
            adverse significance with respect to Hudson or any of its
            subsidiaries or to the value of the Hudson Common Stock; and

which, in the reasonable judgment of TrustCo, makes it inadvisable to proceed
with the Exchange Offer.


            The foregoing conditions are for the sole benefit of TrustCo and may
be asserted by TrustCo on or before the Expiration Date regardless of the
circumstances giving rise to any such conditions (including any action or
inaction by TrustCo) or may be waived on or before the Expiration Date by
TrustCo in whole or in part. The failure by TrustCo to exercise any of the
foregoing rights will not be deemed a waiver of any such right and each such
right will be deemed a continuing right which may be asserted at any time and
from time to time on or before the Expiration Date.


            TERMINATION OF THE HUDSON-COHOES OPTION AGREEMENT


            The Exchange Offer is conditioned, among other things, upon the
termination of the Stock Option Agreement, dated April 25, 2000, between Hudson
and Cohoes (the "Hudson-Cohoes Option Agreement") and the surrender by Cohoes to
Hudson of the options granted to Cohoes thereunder. The Hudson-Cohoes Option
Agreement was entered into in connection with the Hudson-Cohoes Merger
Agreement. Under the Hudson-Cohoes Option Agreement, Hudson granted Cohoes an
unconditional, irrevocable option to purchase up to $3.5 million of Hudson
Common Stock .

            On September 28, 2000, Hudson and Cohoes announced that they had
amended the Hudson-Cohoes Option Agreement to cap the economic value of the
option at $3.5 million.


            Cohoes may exercise the option if, but only if, both an "Initial
Triggering Event" and a "Subsequent Triggering Event" has occurred prior to the
occurrence of an "Exercise Termination Event."


            An "Initial Triggering Event" includes any of the following events
or transactions: (i) Hudson, without Cohoes' prior consent, enters into an
agreement to be acquired (i.e., 10% or more of the voting power of the Hudson
Common Stock), or the Hudson Board recommends that the Hudson shareholders
approve such an acquisition transaction with any person other than Cohoes; (ii)
any person other than Cohoes acquires beneficial ownership (or the right to
acquire beneficial ownership) of 10% or more of the outstanding shares of Hudson
Common Stock; (iii) any person publicly announces that it has



                                       46
<PAGE>


made or intends to make a proposal to engage in an acquisition transaction with
Hudson; (iv) the Hudson Board (without having received Cohoes' consent): (a)
withdraws its recommendation to the Hudson stockholders that they approve the
Hudson-Cohoes Merger; or (b) authorizes, recommends or proposes an agreement to
enter into an acquisition transaction with anyone other than Cohoes; or (c)
provides information to or engages in negotiations with a third party relating
to a possible acquisition transaction; (v) any person (other than Cohoes) files
with the SEC a registration statement or tender offer materials with respect to
a potential exchange offer than would constitute such an acquisition
transaction; (vi) Hudson willfully breaches any covenant or obligation contained
in the Hudson-Cohoes Merger Agreement after an overture is made by a third party
to Hudson or its shareholders to engage in a possible acquisition transaction
and such breach would entitle Cohoes to terminate the Hudson-Cohoes Merger
Agreement and has not been cured within the time period prescribed in the
Hudson-Cohoes Option Agreement or (vii) any person (other than Cohoes and
without Cohoes' consent) files an application or notice with any federal or
state thrift or bank regulatory or antitrust authority to engage in such an
acquisition transaction. The Exchange offer, and TrustCo's activities in
connection therewith and with the TrustCo-Hudson Merger, constitute an "Initial
Triggering Event."


            A "Subsequent Triggering Event" means: (i) the acquisition by any
person (other than Cohoes) of beneficial ownership of 25% or more of the
outstanding Hudson Common Stock; or (ii) the occurrence of an "Initial
Triggering Event" described in clause (i) of the immediately preceding paragraph
(but by substitution 25% for 10%). The Exchange Offer, and TrustCo's activities
in connection therewith and with the TrustCo-Hudson Merger, will constitute a
"Subsequent Triggering Event."


            An "Exercise Termination Event" means any of the following: (i) such
time as the Hudson-Cohoes Merger becomes effective; (ii) a termination of the
Hudson-Cohoes Merger Agreement in accordance with its term; or (iii) the passage
of certain prescribed times after termination of the Hudson-Cohoes Merger
Agreement if such termination follows the occurrence of an "Initial Triggering
Event." By its terms the Option Agreement is not expected to terminate prior to
August 17, 2001.

            Since there has been an Initial Triggering Event, and since the
closing of the Exchange Offer and the TrustCo-Hudson Merger will constitute a
Subsequent Triggering Event, Hudson and Cohoes will need to mutually agree to
terminate the Hudson-Cohoes Option Agreement to satisfy this condition.


            DEFINITIVE TRUSTCO-HUDSON MERGER AGREEMENT


            The Exchange Offer is conditioned, among other things, upon TrustCo
and Hudson entering into a definitive agreement with respect to the
TrustCo-Hudson Merger which is approved by the Hudson Board and Hudson's
shareholders. TrustCo considers the Exchange Offer and the TrustCo-Hudson Merger
to be related steps in one overall transaction whereby TrustCo acquires all of
the issued and outstanding shares of Hudson Common Stock. See "THE EXCHANGE
OFFER--Material Federal Income Taxes." Whether this condition can be satisfied
depends upon the willingness of the Hudson Board to enter into such a definitive
agreement.


            EFFECTIVE REGISTRATION STATEMENT


            The Exchange Offer is conditioned, among other things, upon the
Registration Statement of which this Prospectus is a part becoming effective.
This is a non-waivable condition to the Exchange Offer. This condition has been
satisfied.


WAIVER OF CONDITIONS


            With the exception of the Regulatory Approval Condition, the TrustCo
Stockholder Approval Condition (to the extent the approval of TrustCo's
stockholders is required) and the effectiveness of this Registration Statement
condition, each of the conditions to the offer discussed above must either be
satisfied or waived by TrustCo on or before the Expiration Date.



                                       47
<PAGE>

FEES AND EXPENSES

            TrustCo has engaged Georgeson Shareholder Communications Inc. to act
as TrustCo's information agent (the "Information Agent") with respect to the
Exchange Offer. TrustCo will pay the Information Agent a fee of $10,000 for its
services in connection with the Exchange Offer, plus reimbursement for
out-of-pocket expenses, and will indemnify the Information Agent against certain
liabilities and expenses in connection therewith, including liabilities under
the federal securities laws.

            TrustCo will pay the Exchange Agent reasonable and customary
compensation for its services in connection with the Exchange Offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Exchange Agent
against certain liabilities and expenses in connection therewith, including
liabilities under the federal securities laws.

            Brokers, dealers, commercials banks and trust companies will be
reimbursed by TrustCo for customary mailing and handling expenses incurred by
them in forwarding material to their customers.

ACCOUNTING TREATMENT


            Upon consummation of the Exchange Offer, TrustCo will account for
the acquisition of the Hudson Common Stock as a purchase business combination.
See "PRO FORMA COMBINED FINANCIAL INFORMATION--Summary of Purchase Accounting
Adjustments June 30, 2000."


NASDAQ LISTING

            The outstanding shares of TrustCo Common Stock are, and the shares
of TrustCo Common Stock to be issued in the Exchange Offer and the
TrustCo-Hudson Merger will be, included for quotation on the Nasdaq.

SOURCE OF FUNDS


            The cash portion of the Exchange Consideration, i.e. the $10.20 net
in cash and the amounts necessary for payments in lieu of fractional shares,
will be funded from TrustCo's federal funds sold and from sales of securities
that TrustCo holds as "available for sale."


TREATMENT OF HUDSON STOCK OPTIONS


            Hudson maintains an Employee Stock Ownership Plan ("ESOP") for its
employees and a Stock Option and Incentive Plan for directors, advisory
directors and key employees (collectively the "Option Plans"). Each outstanding
option under the Option Plans will be canceled prior to the consummation date of
the TrustCo-Hudson Merger and the holder thereof will receive from TrustCo, in
payment for such option, cash in the amount of $17.00 less the exercise price of
the stock option. Any resulting fractional shares will be paid in cash. It is
anticipated that the ESOP will be terminated and any remaining unallocated ESOP
shares would be allocated to participants after repayment of the ESOP loan.


                               RECENT DEVELOPMENTS


Cohoes and Hudson Stockholder Meetings

            On August 17, 2000, Cohoes and Hudson each held meetings of
shareholders at which the Hudson-Cohoes Merger Agreement was submitted to
shareholders for their approval. On August 18, 2000, although Hudson announced
that its shareholders had approved the Hudson-Cohoes Merger, Cohoes announced
that its shareholders did not approve the Hudson-Cohoes Merger.

Ambanc Tender Offer

            On July 27, 2000, Ambanc Holding Co., Inc. ("Ambanc") announced its
intent to commence a tender offer for all outstanding shares of Cohoes. The
announcement stated that Ambanc would offer Cohoes' shareholders $16.50 in cash
for each share of Cohoes Common Stock. Ambanc also solicited proxies from Cohoes
shareholders to vote against the Cohoes-Hudson Merger. On August 9, Ambanc
commenced its tender offer. Ambanc has also announced that it has nominated
three persons for election to the Cohoes board of directors at Cohoes' next
annual meeting of shareholders.

Termination of Hudson-Cohoes Merger Agreement

            On September 28, 2000, Hudson and Cohoes announced that they had
terminated the Hudson-Cohoes Merger Agreement. Also on September 28, 2000,
Cohoes announced that its board of directors and management, together with their
financial and legal advisors, would immediately begin a comprehensive
exploration of all strategic options, which could include the sale of Cohoes to
a larger financial institution, and that it had engaged Keefe, Bruyette & Woods,
Inc. to assist in the evaluation of Cohoes' strategic options. Cohoes also
indicated that its board continues to believe that Ambanc's unsolicited tender
offer and the price publicly announced by TrustCo were inadequate and not in the
best interests of Cohoes stockholders.

            The following unaudited pro forma condensed balance sheet and income
statements have been prepared based on the historical results of operations and
financial condition of TrustCo, Hudson and Cohoes. Pro forma adjustments and
assumptions on which they are based are described in the notes following such
balance sheet and income statements. The purchase accounting adjustments were
calculated as of the dates indicated in the notes (primarily June 30, 2000).


            TrustCo has not had access to the Hudson or Cohoes records as part
of its attempt to allocate the cost of its investment in the fair value of the
Hudson and Cohoes assets and liabilities. The allocation of the cost of the
investments reflected in the accompanying pro forma information has been made
based on available information in some instances and otherwise based on
assumptions TrustCo believes to be reasonable. In instances in which there was
no reliable basis to make a reasonable estimate, recorded values were considered
to approximate fair value. Accordingly, for purposes of these pro forma
financial statements, the fair value of loans, deposits and premises and
equipment were considered to be carrying value. The excess of the purchase price
over the fair value of the net assets has been treated as goodwill.


            The information concerning Hudson and Cohoes is derived from
previously filed Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and
previously released press releases. TrustCo does not make any representation
with respect to either Hudson or Cohoes amounts and has not performed any
procedures to ensure their accuracy or reasonableness. Certain Hudson and Cohoes
financial information has been reclassified to conform to TrustCo's financial
presentation.

            The information shown for TrustCo has been prepared from historical
financial information from previously filed Annual Reports on Form 10-K,
Quarterly Reports on Form 10-Q and previously released press releases. The
information is for illustrative purposes only. The companies would likely have
performed differently had they always been combined. The information should not
be relied on as an indication of future results that the combined company will
experience after the transactions are completed, because of a variety of
factors, including access to additional information and changes in value.

            TrustCo also expects to achieve operating cost savings as a result
of the Hudson and Cohoes transactions. See "BACKGROUND OF THE EXCHANGE
OFFER--Benefits of the transaction" No adjustments have been included in the
combined pro forma operating amounts for the anticipated operating cost savings.

                     DESCRIPTION OF TRUSTCO'S CAPITAL STOCK


GENERAL


            TrustCo is presently authorized to issue 100,000,000 shares of
common stock, par value $1.00 per share (referred to in this Prospectus as
"TrustCo Common Stock"), and 500,000 shares of preferred stock, par value $10.00
per share. At July 31, 2000, there were 53,548,191 shares of TrustCo Common

COMMON STOCK

            VOTING RIGHTS

            Holders of TrustCo Common Stock possess exclusive voting rights in
TrustCo, except to the extent that shares of preferred stock issued in the
future may have voting rights, if any. Each holder of shares of TrustCo Common
Stock is entitled to one vote for each share held of record on all matters
submitted to a vote of holders of the TrustCo Common Stock.

            DIVIDEND RIGHTS


            Holders of TrustCo Common Stock are entitled to receive dividends
when, as and if declared by TrustCo's Board of Directors (the "TrustCo Board")
out of funds legally available therefor, subject to any preferential dividend
rights which may attach to preferred stock which may be issued by TrustCo in the
future. Under the New York Business Corporation Law (the "New York Law"),
TrustCo may pay dividends on TrustCo Common Stock unless TrustCo is or would
thereby be made insolvent. Moreover, TrustCo may pay dividends out of surplus
only such that the net assets of TrustCo remaining thereafter is at least equal
to the amount of its stated capital. If any dividend is paid by TrustCo, in
whole or in part, from sources other than earned surplus, the stockholders of
TrustCo must be notified of that fact. The ability of TrustCo Bank to pay cash
dividends, which is expected to be TrustCo's principal source of income, is
restricted by applicable banking laws. Such dividends have previously been
TrustCo's principal source of income.


            LIQUIDATION RIGHTS

            In the event of a liquidation, dissolution or winding up of TrustCo,
each holder of TrustCo Common Stock would be entitled to receive, after payment
of all debts and liabilities of TrustCo, a pro rata portion of all assets of
TrustCo available for distribution to holders of the TrustCo Common Stock. If
any preferred stock is issued, the holders thereof may have a priority in
liquidation or dissolution over the holders of the TrustCo Common Stock.

            OTHER CHARACTERISTICS

            Holders of TrustCo Common Stock do not have preemptive rights with
respect to any additional shares of TrustCo which may be issued. The shares of
TrustCo Common Stock presently outstanding are, and the shares of TrustCo Common
Stock to be issued pursuant to the Exchange Offer will be, when issued and
delivered as described herein, duly authorized, validly issued, fully paid and
non-assessable. There are no redemption or sinking fund provisions applicable to
the shares of TrustCo Common Stock.

of such shares and the qualifications, limitations and restrictions thereof. The
preferred stock may rank prior to the common stock as to dividend rights or
liquidation preference, or both, and may have full or limited voting rights. The
TrustCo Board has no present intention to issue any of the preferred stock.

as amended, and other corporate documents of TrustCo. The rights of holders of
Hudson Common Stock, which are governed by the DGCL and Hudson's Certificate and
Bylaws, as amended, differ in certain respects from the rights which such
holders would have as stockholders of TrustCo. A summary of the material
differences between the respective rights of Hudson and TrustCo stockholders is
set forth below.

STOCKHOLDER VOTE REQUIRED FOR CERTAIN TRANSACTIONS

            BUSINESS COMBINATIONS

                        TRUSTCO

            The New York Law generally requires that mergers, consolidations and
sales, leases, exchanges, or other distributions of all of the assets of a
corporation be approved by a vote of not less than two-thirds of all outstanding
shares entitled to vote on such transactions. Moreover, generally, holders of
shares of any class or series have the right to vote, and to vote as a class, on
certain mergers and consolidations which contain provisions that exclude or
limit their right to vote, or adversely affect certain of their rights, or
authorize shares which have a preference over their shares. In such cases, in
addition to the vote of the holders of two-thirds of all outstanding shares
entitled to vote thereon, the merger or consolidation must be approved by the
holders of a majority of all outstanding shares of such class or series.

            TrustCo's Certificate includes a so-called "fair consideration"
provision, which provides that a "business combination" (including a merger,
consolidation or acquisition of substantially all assets) involving TrustCo, or
any subsidiary of TrustCo, with any person or entity beneficially owning
directly or indirectly more than 5% of TrustCo's outstanding voting stock (a
"TrustCo 5% stockholder") may not be consummated, even if the normal statutory
requirements are met, unless: (i) the transaction is approved by at least
two-thirds of the members of the TrustCo Board who are not affiliated with the
TrustCo 5% stockholder; or (ii) the transaction meets certain minimum price
requirements (in either of which cases only the normal stockholder and director
approval requirements of the New York Law would govern the transaction). The
primary purpose of TrustCo's "fair consideration" provision is to provide
additional safeguards for the remaining stockholders in the event that an
individual or entity becomes a majority stockholder of TrustCo. If TrustCo comes
under the control of a single person or entity, substantial inequities could
befall the minority stockholders. Accordingly, this "fair consideration"
provision was included in TrustCo's Certificate to make it more likely that any
acquisition of TrustCo will involve payment of a fair price to all stockholders
of TrustCo.

                        HUDSON

            Hudson's Certificate provides for a greater than majority
stockholder approval requirement for certain business combinations with
interested stockholders. Under Hudson's Certificate, certain business
combinations with an interested stockholder require the affirmative vote of the
holders of at least 80% of the voting power of the outstanding shares of stock
of Hudson entitled to vote in the election of directors. Generally, an
interested stockholder is any person, other than Hudson or any subsidiary of
Hudson, that is the beneficial owner, directly or indirectly, of more than 10%
of the voting power of the outstanding voting stock of Hudson. The business
combination provisions relating to interested stockholders also apply to
affiliates of interested stockholders. Business combinations subject to the 80%
stockholder approval requirement include: (i) any merger or consolidation of
Hudson or any subsidiary of Hudson with an interested stockholder or affiliate
thereof; (ii) any sale, lease, exchange, mortgage, pledge, transfer or other
disposition of assets of Hudson or any Hudson subsidiary to an interested
stockholder having an aggregate fair market value equaling or exceeding 25% or
more of the combined assets of Hudson and its subsidiaries; (iii) the issuance
or transfer by Hudson or any Hudson subsidiary of any stock of Hudson or any
Hudson subsidiary to an interested stockholder for any property equaling or
exceeding 25% of the combined assets of Hudson and any Hudson subsidiaries; (iv)
the adoption of any plan for the liquidation or dissolution of Hudson proposed
by or on behalf of an interested stockholder or affiliate thereof; and (v) any
reclassification of securities or recapitalization of Hudson, or any merger or
consolidation of Hudson with any of its subsidiaries or any other transaction
that has the effect of increasing the proportionate share of the outstanding
shares of any class of equity or convertible securities of Hudson or any
subsidiary of Hudson directly or indirectly owned by an interested stockholder
or affiliate thereof. A business combination with an interested stockholder may
avoid the 80% stockholder



                                       68
<PAGE>

approval requirement, needing only an affirmative vote of a majority of the
voting power of the outstanding shares of stock of Hudson entitled to vote in
the election of directors, if: (a) the business combination does not involve
cash or other consideration being received by the stockholders of Hudson solely
in their capacity as stockholders of Hudson and the business combination has
been approved by a majority of the disinterested directors of Hudson; or (b) the
business combination has been approved by a majority of the disinterested
directors of Hudson, or each of the following conditions are met: (1) the fair
market value of the consideration received per share by the holders of Hudson
Common Stock equals or exceeds the higher of certain fair price determinations;
(2) there has been no reduction of dividends or failure to pay dividends after
the time the interested stockholder became an interested stockholder, except as
approved by a majority of disinterested directors; (3) the interested
stockholder and its affiliates have not become the beneficial owners of any
additional shares of voting stock of Hudson after the interested stockholder
became an interested stockholder; (4) the interested stockholder has not
received the benefit, directly or indirectly, of any loans, advances,
guarantees, pledges or other financial assistance; and (5) a proxy or
information statement describing the proposed business combination and complying
with the requirements of the 1934 Act has been mailed to stockholders of Hudson
at least 30 days prior to the consummation of such business combination.

            REMOVAL OF DIRECTORS

                        TRUSTCO

            The New York Law provides that any or all of the directors of
TrustCo may be removed for cause by a vote of the stockholders. TrustCo's
Certificate specifies that an affirmative vote of at least a majority of its
outstanding stock is needed to approve any matter on which stockholders are
entitled to vote.

                        HUDSON

            Hudson's Certificate provides that any director or the entire Hudson
Board may be removed from office at any time, but only for cause and only by the
holders of at least 80% of the voting power of all of the outstanding shares of
capital stock of Hudson entitled to vote generally in the election of directors.
Hudson's 80% stockholder vote requirement for removal of directors precludes a
majority stockholder from circumventing Hudson's classified Hudson Board by
decreasing the size of the Hudson Board until its nominees have a numerical
majority or by removing directors not up for election, filling the resulting
vacancy with its nominees, and thereby gaining control of the Hudson Board.
Stockholders of Hudson may not remove directors without cause, making it more
difficult for a majority stockholder to control the Hudson Board. The
restriction on director removal found in Hudson's Certificate also makes it more
difficult for stockholders of Hudson to change the composition of the Hudson
Board even where the stockholders believe in good faith that such a change would
be beneficial to Hudson and to the stockholders of Hudson.

            AMENDMENTS TO CERTIFICATE OF INCORPORATION AND BYLAWS

                        TRUSTCO

            TrustCo's Certificate requires an affirmative vote of at least
two-thirds of TrustCo's voting stock to change, modify, or repeal any provision
of TrustCo's Certificate or Bylaws.

                        HUDSON

            The DGCL provides that the certificate of incorporation of a
Delaware corporation may be amended only if first approved by the corporation's
board of directors and thereafter by a majority of the outstanding stock
entitled to vote thereon. The DGCL also provides that, if a greater than
majority stockholder vote is required to effect an action under a certain
article of a Delaware corporation's


                                       69
<PAGE>

certificate of incorporation, then amending such an article likewise requires
such a greater than majority stockholder vote.

            Hudson's Certificate provides that Hudson may amend or repeal any
provision contained in Hudson's Certificate in the manner prescribed described
above pursuant to the DGCL. Hudson's Certificate further provides that the
affirmative vote of at least 80% of the voting power of all of the outstanding
shares of the capital stock of Hudson entitled to vote generally in the election
of directors (after giving effect to the 10% Limit described herein under the
caption "COMPARISON OF SHAREHOLDER RIGHTS -- Anti-takeover Statutes and
Provisions -- HUDSON") is required to amend or repeal the provisions of: (i)
Article THIRTEENTH (relating to amending the Hudson's Certificate); (ii)
Sections B or C of Article FOURTH (relating to voting restrictions imposed on
stockholders owning in excess of 10% of the outstanding shares of Hudson Common
Stock); (iii) Sections C and D of Article FIFTH (relating to stockholder special
meetings and stockholder action by written consent); (iv) Article SIXTH
(relating to the number, classification, qualification, disqualification,
director nominations, filling of vacancies and removal of directors of Hudson);
(v) Article SEVENTH (relating to amending the Bylaws); (vi) Article EIGHTH
(relating to approval of business combinations with an interested stockholder or
its affiliates); (vii) Article TENTH (relating to Hudson's purchase of stock
from an interested person); and (viii) Article ELEVENTH (relating to
indemnification).

            Hudson's Bylaws provide that the Hudson Board may amend or repeal
the Bylaws upon the vote of a majority of the whole board thereof. The
stockholders of Hudson, upon the affirmative vote of the holder of at least 80%
of the voting power of the voting stock (after giving effect to the 10% Limit),
also have the power to amend or repeal the Bylaws of Hudson.

            VOTING RIGHTS

                        TRUSTCO

            Holders of TrustCo Common Stock are entitled to one vote per share
in the election of directors and in all other matters to be voted upon by the
stockholders generally. A stockholder of TrustCo may vote in person or by proxy.
Directors of TrustCo are elected by a plurality of the stockholder votes cast
and stockholders of TrustCo Common Stock are not entitled to cumulative voting
in the election of directors. All other matters voted on by stockholders are
determined by a majority of the stockholder votes cast, except those matters
specifically requiring a greater than majority vote pursuant to the New York Law
or TrustCo's Certificate.

                        HUDSON

            In accordance with the DGCL, and as provided in the Bylaws of
Hudson, each outstanding share of Hudson Common Stock is entitled to one vote on
each matter voted on at a stockholders' meeting. A stockholder of Hudson may
vote in person or by proxy. Directors of Hudson are elected by a plurality of
the stockholder votes cast, and stockholders of Hudson are not entitled to
cumulative voting in the election of directors. All other matters voted on by
stockholders are determined by a majority of the stockholder votes cast, except
those matters specifically requiring a greater than majority vote pursuant to
the DGCL or Hudson's Certificate. Notwithstanding the foregoing, Article FOURTH,
Section C, of Hudson's Certificate provides that no person who beneficially owns
more than 10% of the outstanding shares of Hudson Common Stock may vote shares
in excess of that limit. See "COMPARISON OF SHAREHOLDER RIGHTS -- Anti-Takeover
Statutes and Provisions -- HUDSON."


                                       70

SPECIAL MEETING OF STOCKHOLDERS; STOCKHOLDER ACTION BY WRITTEN CONSENT

            TRUSTCO

            The New York Law provides that special meetings of the stockholders
of a New York corporation may be called by the board of directors and by such
person or persons as may be so authorized by the certificate of incorporation or
the bylaws. TrustCo's Certificate provides that special meetings of stockholders
of TrustCo may be called at the request of at least two-thirds of the shares of
TrustCo Common issued and outstanding. In addition, the Bylaws provide that a
special meeting of the stockholders may be called at any time by the TrustCo
Board or by TrustCo's Chief Executive Officer.

            Pursuant to the New York Law, stockholders of TrustCo may take any
action without a meeting by written consent, which consent must set forth the
action so taken and be signed by the holders of all of the outstanding shares
entitled to vote thereon. Written consent given by the holders of all
outstanding shares entitled to vote has the same effect as a unanimous vote of
stockholders.

            HUDSON

            In accordance with the DGCL, Hudson's' Bylaws provides that special
meetings of stockholders of Hudson may be called only by the Hudson Board
pursuant to a resolution adopted by a majority of the total number of directors
which Hudson would have if there were no vacancies on the Hudson Board.
Hudson's' Bylaws also provides that any action required or permitted to be taken
by the stockholders of Hudson must be effected at a duly called annual or
special stockholders' meeting and may not be effected by any consent in writing
by such stockholders. The DGCL, in the absence of this provision, permits action
by written consent of stockholders signed by the holders of the number of shares
that would be required to effect the action at a meeting. Hudson's' restriction
against stockholders' ability to call a special stockholders' meeting and
against stockholder action by written consent is more restrictive than TrustCo's
2/3 stockholder vote required to call a special meeting and stockholders' act by
written consent of all of TrustCo's stockholders. Hudson's more restrictive
provisions preclude attempts by stockholders to disrupt the business of Hudson
between annual stockholders' meetings, and make it impossible for a stockholder
or stockholder group to take action where such action is opposed by a majority
of the Hudson Board and management of Hudson. Hudson's' more restrictive
provisions also preclude the removal of directors, even if cause exists or a
director becomes disqualified, until the next annual stockholders' meeting,
where such removal is opposed by a majority of the Hudson Board.

DISSENTERS' RIGHTS

            TRUSTCO

            The New York Law provides that dissenting stockholders are entitled
to receive payment of the "fair value" of their shares in connection with
certain mergers or consolidations of which the corporation is a party and sales
or exchanges of all or substantially all of the assets of a corporation. Under
the New York Law, dissenting stockholders: (i) may withdraw their notice of
election to dissent within certain specific time periods prior to their
acceptance of a corporation's offer to purchase their shares; (ii) are entitled
to an advance payment which accompanies a corporation's offer to purchase their
shares, if the corporate action has been consummated; and (iii) bear their own
costs and expenses as to any court proceeding for a determination of the fair
value of their shares.

            HUDSON

            The DGCL provides that, unless the certificate of incorporation of a
Delaware corporation provides otherwise, no dissenters' appraisal rights are
available to holders of shares that are listed on a national securities exchange
or designated as a national market system security on an interdealer quotation
system by NASD, or are held of record by more than 2,000 stockholders. As the
shares of


                                       71
<PAGE>

Hudson Common Stock are a national market system security traded on Nasdaq and
Hudson's Certificate does not provide for dissenters' appraisal rights, holders
of Hudson Common Stock have no dissenters' appraisal rights in any merger,
consolidation or disposition of assets. Stockholders of Hudson may not,
therefore, assert dissenters' appraisal rights in connection with the Exchange
Offer or the TrustCo-Hudson Merger.

ANTI-TAKEOVER STATUTES AND PROVISIONS

            TRUSTCO

            In general, the New York Law prohibits any business combination
(e.g. mergers, consolidations, and acquisitions of substantially all of the
assets) between a New York corporation and an "interested stockholder" (defined
as any owner of 20% or more of the voting stock of such corporation) unless the
corporation's board of directors has approved the business combination or the
stock acquisition by which the related party's interest reached 20% (the "Stock
Acquisition") prior to the date of the Stock Acquisition. This restriction
applies for five years after the date of the Stock Acquisition. Thereafter, the
corporation may enter into a business combination with the related party: (i) if
the combination is approved by a majority of the corporation's voting stock
beneficially owned by stockholders other than the related party; or (ii) if such
disinterested stockholders receive a price for their shares equal to or greater
than a price determined in accordance with a statutory formula intended to
assure that stockholders receive an equitable price in the business combination.
As a New York corporation, TrustCo and any potential acquiror of TrustCo would
be subject to this provision.

            TrustCo's Certificate and Bylaws contain several provisions which
may be deemed to be "anti-takeover" in nature. TrustCo's Certificate contains a
"fair consideration" provision which is discussed under "COMPARISON OF
SHAREHOLDER RIGHTS -- Stockholder Vote Required for Certain Transactions --
BUSINESS COMBINATIONS -- TRUSTCO." TrustCo's Certificate also provides for a
classified board of directors, under which one-third of the directors are
elected to three-year terms at each annual stockholders' meeting. In effect, the
classified board may increase the time required for any one or more persons
owning a majority or controlling block of stock to elect a majority of the
directors. Without a classified board, a change in control can be accomplished
at a single annual stockholders' meeting. In contrast, with a classified board,
at least two successive annual stockholders' meetings may be required to effect
a change in control. The TrustCo Board and management of TrustCo believe that a
classified board may help to moderate the pace of any change in control of the
TrustCo Board and, by increasing the stability of the TrustCo Board, may also
increase its effectiveness. Conversely, the additional time required to obtain
control of the TrustCo Board also tends to discourage a tender offer or takeover
bid, many of which are made at premium prices to stockholders.

            HUDSON

            The DGCL has a "freeze provision" that generally prohibits any
business combination, such as a merger or consolidation, between a Delaware
corporation and an interested stockholder (which is generally defined as any
owner of 15% or more of the outstanding voting stock of a corporation) for three
years after the date on which such stockholder becomes an interested
stockholder. The Delaware statute provides that if any of the following
conditions are met, Delaware's three-year freeze provision will not apply: (i)
prior to such date the board of directors of the corporation approved either the
business combination or the transaction by which the interested stockholder
became an interested stockholder; (ii) upon consummation of the transaction
which resulted in the stockholder becoming an interested stockholder, the
interested stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced (excluding shares held by
persons who are directors and also officers and by certain employee stock
ownership plans); or (iii) on or subsequent to such date the business
combination is approved by the board of directors of the corporation and
authorized at an

                                       72
<PAGE>

annual or special meeting of the stockholders by the affirmative vote of at
least two-thirds of the outstanding voting stock of the corporation which is not
owned by the interested stockholder.

            Under the terms of Hudson's Certificate, a record owner of Hudson
Common Stock who beneficially owns, directly or indirectly, in excess of 10% of
the outstanding shares of Hudson Common Stock is not entitled to vote the shares
held in excess of 10% of the outstanding shares of Hudson Common Stock. The
number of shares which may be voted by any record owner owning shares in excess
of the 10% Limit is equal to the total number of votes which a single record
owner of all Hudson Common Stock owned by such person would be entitled to cast,
multiplied by a fraction, the numerator of which is the number of shares
beneficially owned by such person and owned of record by such record owner and
the denominator of which is the total number of shares of Hudson Common Stock
beneficially owned by such person owning shares in excess of the 10% Limit.

            As with TrustCo, Hudson's Certificate provides that the Hudson Board
is divided into three classes, as nearly equal in number as possible, which are
elected for staggered three-year terms. For additional discussion of provisions
which may be deemed to have an anti-takeover effect, see "COMPARISON OF
SHAREHOLDER RIGHTS -- Special Meeting of Stockholders; Stockholder Action by
Written Consent -- HUDSON", and "-- Stockholder Vote Required for Certain
Transactions -- REMOVAL OF DIRECTORS -- HUDSON."

INDEMNIFICATION

            TRUSTCO

            The New York Law contains provisions permitting indemnification of
officers and directors so long as such persons acted in good faith, and in a
manner he or she reasonably believed to be in, or not opposed to, the best
interests of the corporation and, with respect to a criminal proceeding, if he
or she had no reason to believe his or her conduct was unlawful. TrustCo's
Bylaws generally permit indemnification, PROVIDED, HOWEVER, that no
indemnification will be made to any officer or director if a judgement or final
adjudication establishes that his or her acts were committed in bad faith or
were the result of an act of deliberate dishonesty, and were material to the
cause of action so adjudicated, or that he or she personally gained a financial
profit or other advantage to which he or she was not entitled.

            HUDSON

            The DGCL grants Delaware corporations broad indemnification powers,
including the authority to provide forms of indemnification in addition to the
types of indemnification specifically set forth within the DGCL. Hudson's
Certificate provides mandatory indemnification for each person who was or is
made a party or threatened to be made a party to or is otherwise involved in any
proceeding by reason of the fact that he or she is or was a director or officer
of Hudson or a subsidiary of Hudson or is or was serving at the request of
Hudson as a director, officer, employee or agent of another corporation. Such
mandatory indemnification covers the alleged action whether or not such person
was acting in their official capacity. Such indemnification covers all expense,
liability and loss, including attorneys' fees, judgments, fines, excise taxes or
penalties and amounts paid in settlement reasonably incurred by the indemnitee
in connection with the proceeding. Hudson's Certificate provides indemnification
to an indemnitee who initiates a proceeding only if the proceeding was
authorized by the Hudson Board or was initiated to enforce indemnification
rights. Hudson's Certificate provides for payment of indemnification expenses in
advance of a proceeding's final disposition provided the indemnitee first
delivers to Hudson an undertaking by or on behalf of such indemnitee to repay
all amounts so advanced if it is ultimately determined that the indemnitee is
not entitled to be indemnified for such expense. In addition to mandatory
indemnification, Hudson may in accordance with Hudson's Certificate, to the
extent authorized by the Hudson Board, grant rights to indemnification and to
the advancement of indemnification expenses to any employee or agent of Hudson
to the fullest extent that Hudson is


                                       73
<PAGE>

authorized to indemnify and advance expenses to the directors and officers of
Hudson. Hudson's Certificate also authorizes Hudson to maintain insurance to
protect Hudson and any director, officer, employee or agent of Hudson or another
corporation against any expense, liability or loss, whether or not Hudson would
have the power to indemnify such person against such expense, liability or loss
under the DGCL.

LIMITATION OF LIABILITY OF DIRECTORS

            TRUSTCO

            TrustCo's Certificate provides that, to the fullest extent that the
New York Law permits elimination or limitation of the liabilities of directors,
no director of TrustCo will be liable to the corporation or its stockholders for
any breach of duty in such capacity. The New York Law provides that a director
will not be liable if he or she performed his or her duties as a director,
including duties as a member of any committee thereof, in good faith and with
that degree of care which an ordinarily prudent person in a like position would
use under similar circumstances.

            HUDSON

            Hudson's Certificate provides that a director of Hudson will not be
personally liable to Hudson or the stockholders of Hudson for monetary damages
for breach of fiduciary duty as a director, except for liability resulting from:
(i) any breach of the director's duty of loyalty to Hudson or the stockholders
of Hudson; (ii) acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law; (iii) unlawful payment of dividend or
unlawful stock purchases or redemptions; or (iv) any transaction from which the
director derived an improper personal benefit. Stockholders of Hudson do not,
therefore, have a cause of action against a director based upon negligent
business decisions, including those relating to attempts to acquire control of
Hudson. Hudson's Certificate does not, however, preclude all equitable remedies
for breach of the duty of care, although such remedies might not be available as
a practical matter. Hudson's limitation of director liability may reduce the
likelihood of derivative litigation against directors and discourage or deter
stockholders or management from bringing a lawsuit against directors for breach
of their duty of care, even though such an action, if successful, might
otherwise have been beneficial to Hudson and its stockholders.

CONSIDERATION OF NON-STOCKHOLDER INTERESTS

            TRUSTCO

            The New York Law specifically authorizes directors, in considering
the best interests of a corporation, to consider the short-term and long-term
interests of the corporation and its stockholders as well as the short-term or
long-term effects of any action upon: (i) the corporation's prospects for
potential growth, development, productivity and profitability; (ii) the
corporation's current employees; (iii) the corporation's retired employees and
other beneficiaries receiving or entitled to receive retirement, welfare or
similar benefits from or pursuant to any plan sponsored, or agreement entered
into, by the corporation; (iv) the corporation's customers and creditors; and
(v) the ability of the corporation to provide, as a going concern, goods,
services, employment opportunities and employment benefits and otherwise to
contribute to the communities in which it does business. The New York Law does
not create any duties of any director to any person or entity to consider or
afford any particular weight to any of the foregoing criteria, nor does it
abrogate any duty of the directors, either statutory or recognized by common law
or court decisions.

            HUDSON

            The DGCL does not address a Delaware director's ability to consider
non-stockholder interests when discharging his or her duties. Delaware case law,
however, provides that in discharging his or her


                                       74
<PAGE>


responsibilities, a board of directors of a Delaware corporation must limit
consideration of non-stockholder interests, and that a board of directors of a
Delaware corporation may consider non-stockholder interests only if those
interests are rationally related to benefits accruing to the stockholders of the
Delaware corporation. REVLON, INC. V. MACANDREWS & FORBES HOLDINGS, INC., 506
A.2d 173 (Del. 1986). Delaware case law further provides that, when a board of
directors of a Delaware corporation decides to sell a Delaware corporation,
concern for non-stockholder interests is inappropriate. ID.

            Hudson's Certificate grants the Hudson Board broader discretion than
that authorized by Delaware case law. Specifically, Hudson's Certificate
provides that the Hudson Board may, when evaluating any tender or exchange
offer, any offer to merge or consolidate Hudson with another entity or any offer
to purchase all or substantially all of the assets of Hudson, give due
consideration to all relevant factors including, without limitation, the social
and economic effect of acceptance of any such offer on present and future
customers and employees of Hudson and subsidiaries of Hudson, the communities in
which Hudson and its subsidiaries operate or are located, and the ability of
Hudson and its subsidiaries to fulfill their respective corporate or banking
objectives.

                       TENDER, PROXY AND POWER OF ATTORNEY

            The undersigned, the registered holder of shares of common stock
(the "Shares") of the Company as described in the Exchange Offer referred to
above, or the legal representative of the registered holder, hereby accepts,
with respect to the Shares tendered, the offer of TrustCo Bank Corp NY
("Offeror"), receipt of which is hereby acknowledged, to acquire the Shares upon
the terms and subject to the conditions of the Exchange Offer.

            Accordingly, subject to and effective upon the acquisition by
Offeror (pursuant to the Exchange Offer) of the Shares tendered herewith, the
undersigned hereby assigns and transfers to or upon the order of Offeror such
Shares, including any and all declared but unpaid dividends and other
distributions on such Shares, and hereby constitutes and appoints ChaseMellon
Shareholder Services (the "Exchange Agent") the true and lawful agent and
attorney-in-fact of the undersigned with respect to such Shares with full power
of substitution (such power of attorney is deemed to be an irrevocable power
coupled with an interest) to: (i) deliver the Shares, together with any and all
evidences of transfer and authenticity which may be required by the Exchange
Agent, to or upon the order of Offeror upon receipt by the Exchange Agent, as
the undersigned's agent, of the shares of Offeror's common stock as set forth in
the Exchange Offer; (ii) do all things necessary and appropriate for the
transfer of such Shares on the Company's books; (iii) exercise all rights of
legal and beneficial ownership of such Shares to which the undersigned would be
entitled by virtue of the ownership of such Shares, in accordance with the terms
of the Exchange Offer; and (iv) receive all dividends and other distributions
due or rights issued in respect to the Shares to which the undersigned would be
entitled by virtue of the ownership of such Shares, all in accordance with the
terms of the Exchange Offer. Upon such acceptance for acquisition, all prior
proxies and powers of attorney given by the undersigned with respect to such
Shares will, without further action, be revoked and no subsequent proxies or
powers of attorney may be given and, if given, will not be deemed effective.

            The undersigned hereby represents and warrants that the undersigned
has full power and authority to tender, exchange, assign and transfer the Shares
and that Offeror will acquire good and unencumbered title thereto, free and
clear of all liens, restrictions, charges, voting agreements and encumbrances
and not subject to any adverse claim. The undersigned will, upon request,
execute and deliver any additional documents deemed by the Exchange Agent or
Offeror to be necessary or desirable to complete the exchange, assignment and
transfer of the Shares.

            All authority herein conferred or agreed to be conferred survives
the death or incapacity of the undersigned and any obligations of the
undersigned hereunder are binding upon the heirs, personal representatives,
successors and assigns of the undersigned. Except as stated in the Exchange
Offer, this tender is irrevocable.

            The undersigned understands that acceptance of the offer contained
in the Exchange Offer constitutes an agreement between the undersigned and
Offeror, in accordance with the terms and conditions precedent of the Exchange
Offer, only when a duly executed and properly completed copy of this Letter of
Transmittal, together with any other required documents (including, but not
limited to, the Shares), are received by the Exchange Agent. The undersigned
further acknowledges receipt and has read the contents of the Exchange Offer and
recognizes the various conditions to the offer that are set forth in the
Exchange Offer.

the Exchange Offer in the name of the undersigned. Similarly, please mail such
shares, unless otherwise indicated herein under "Special Delivery Instructions,"
and/or send any appropriate documents if a Share is not exchanged, to the
undersigned at the address shown below the undersigned's signature. The
undersigned recognizes that Offeror has no obligation to transfer any Shares
from the name of the registered holder thereof if Offeror does not acquire such
Shares pursuant to the Exchange Offer.

                               FORMING PART OF THE
                   TERMS AND CONDITIONS OF THE EXCHANGE OFFER

1. SIGNATURE GUARANTEE. No signature guarantee is required if this Letter of
Transmittal is signed by the registered owner of the Shares tendered with this
Letter of Transmittal and delivery is to be made directly to such registered
owner. If such registered owner has completed either the box entitled "Special
Payment Instructions" or the box entitled "Special Delivery Instructions" on the
previous page, all signatures on this Letter of Transmittal must be guaranteed
by a firm which is a member of a registered national securities exchange or of
the National Association of Securities Dealers, Inc. or by a commercial bank or
trust company having an office or correspondent in the United States of America.

2. EXECUTION AND DELIVERY. This Letter of Transmittal or a facsimile thereof
must be properly filled in and signed by the registered owner or owners of the
Shares being tendered and should be mailed or delivered with the Shares to the
Exchange Agent at the appropriate address set forth herein. The method of
delivery of all documents is at the election and risk of the owners of the
Shares being tendered. However, it is suggested that all documents be delivered
to the Exchange Agent in person or, if sent by mail, be sent by registered mail,
return receipt requested, properly insured. No alternative, conditional or
contingent tenders will be accepted. All tendering owners of a Share, by
execution of this Letter of Transmittal, waive any right to receive any notice
of the acceptance of their tender.

3. DESCRIPTION OF SHARES. The Holder should complete the Description of Shares
on the preceding page. The name of the "registered holder" should be the name on
the certificate or a duly executed stock power or comparable document.

4. COMPLETION OF LETTER OF TRANSMITTAL. Signatures on all documents must
correspond with the name of the registered holder of the tendered Shares as set
forth on page 3 of this Letter of Transmittal (under the heading "Description of
Shares") without alteration, enlargement or any change whatsoever, unless an
authorized representative is signing on behalf of the registered owner. If the
Shares tendered hereby are owned of record by two or more joint owners, all such
owners must sign this Letter of Transmittal. If this Letter of Transmittal is
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and proper evidence
satisfactory to Offeror of their authority so to act must be submitted to the
Exchange Agent.

5. ADDITIONAL COPIES. Additional copies of the Exchange Offer and this Letter of
Transmittal may be obtained from the Exchange Agent at its address set forth on
the cover page of this Letter of Transmittal.

6. TRANSFER TAXES. Transfer taxes imposed as a result of the purchase pursuant
to the Exchange Offer, if any, will be paid by Offeror, except that applicable
transfer taxes will be deducted from a cash payment where such payment is to be
made to other than the registered holder, thus involving an additional transfer.


7. WAIVER OF CONDITIONS. The conditions set forth in this Letter of Transmittal
are for the sole benefit of Offeror and may be asserted on or before the
Expiration Date by Offeror regardless of the circumstances giving rise to any
such conditions or may be waived at any one time and from time to time on or
before the Expiration Date in Offeror's sole discretion.


8. TAXPAYER IDENTIFICATION NUMBER, SUBSTITUTE FORM W-9. The tendering holder of
a Share is required to provide the Exchange Agent with his correct Taxpayer
Identification Number ("TIN") on Substitute Form W-9 on the page following the
last page of these instructions. Failure to provide the information on the form
may subject the tendering holder to 31% withholding on the payment of the
exchange consideration. If such holder is an individual, the taxpayer
identification number is his social security number. The box in Part 3 of the
form may be checked if the tendering holder has not been issued a TIN and has
applied for a number or intends to apply for a number in the near future. If the
box in Part 3 is checked and the Exchange Agent is not provided with a TIN
within 60 days, the Exchange Agent will withhold 31% on all payments of the
exchange consideration thereafter until a TIN is provided to the Exchange Agent,
and the holder may be subject to a $500 penalty imposed by the Internal Revenue
Service. In addition, payments that are made to such holder with respect to an
exchanged Share pursuant to the Exchange Offer may be subject to backup
withholding. If the backup withholding applies, the Exchange Agent is required
to withhold 31% of any payments made to the holder of a Share. Backup
withholding is not an additional tax. Rather, the tax liability of persons
subject to backup withholding will be reduced by the amount of tax withheld. If
withholding results in an overpayment of taxes, a refund may be obtained.

     withholding.
CERTIFICATION INFORMATION - You must cross out Item (2) above if you have been
notified by the IRS that you are subject to backup withholding because of under

withholding, do not cross out Item (2). The certification requirement does not

                                  APPENDIX B

          SECTION 203 OF THE DELAWARE GENERAL BUSINESS CORPORATION LAW
203 BUSINESS COMBINATIONS WITH INTERESTED STOCKHOLDERS.

            (a) Notwithstanding any other provisions of this chapter, a
corporation shall not engage in any business combination with any interested
stockholder for a period of 3 years following the time that such stockholder
became an interested stockholder, unless:

            (1) prior to such time the board of directors of the corporation
approved either the business combination or the transaction which resulted in
the stockholder becoming an interested stockholder, or

            (2) upon consummation of the transaction which resulted in the
stockholder becoming an interested stockholder, the interested stockholder owned
at least 85% of the voting stock of the corporation outstanding at the time the
transaction commenced, excluding for purposes of determining the number of
shares outstanding those shares owned (i) by persons who are directors and also
officers and (ii) employee stock plans in which employee participants do not
have the right to determine confidentially whether shares held subject to the
plan will be tendered in a tender or exchange offer, or

            (3) at or subsequent to such time the business combination is
approved by the board of directors and authorized at an annual or special
meeting of stockholders, and not by written consent, by the affirmative vote of
at least 66-2/3% of the outstanding voting stock which is not owned by the
interested stockholder.

            (b) The restrictions contained in this section shall not apply if:

            (1) the corporation's original certificate of incorporation contains
a provision expressly electing not to be governed by this section;

            (2) the corporation, by action of its board of directors, adopts an
amendment to its bylaws within 90 days of the effective date of this section,
expressly electing not to be governed by this section, which amendment shall not
be further amended by the board of directors.

            (3) the corporation, by action of its stockholders, adopts an
amendment to its certificate of incorporation or bylaws expressly electing not
to be governed by this section, provided that, in addition to any other vote
required by law, such amendment to the certificate of incorporation or bylaws
must be approved by the affirmative vote of a majority of the shares entitled to
vote. An amendment adopted pursuant to this paragraph shall be effective
immediately in the case of a corporation that both (i) has never had a class of
voting stock that falls within any of the three categories set out in subsection
(b)(4) hereof, and (ii) has not elected by a provision in its original
certificate of incorporation or any amendment thereto to be governed by this
section. In all other cases, an amendment adopted pursuant to this paragraph
shall not be effective until 12 months after the adoption of such amendment and
shall not apply to any business combination between such corporation and any
person who became an interested stockholder of such corporation on or prior to
such adoption. A bylaw amendment adopted pursuant to this paragraph shall not be
further amended by the board of directors;

            (4) the corporation does not have a class of voting stock that is
(i) listed on a national securities exchange, (ii) authorized for quotation on
The Nasdaq Stock Market or (iii) held of record by more than 2,000 stockholders,
unless any of the foregoing results from action taken, directly or indirectly,
by an interested stockholder or from a transaction in which a person becomes an
interested stockholder;

            (5) a stockholder becomes an interested stockholder inadvertently
and (i) as soon as practicable divests itself of ownership of sufficient shares
so that the stockholder ceases to be an interested stockholder and (ii) would
not, at any time within the 3 year period immediately prior to a


                                      B-1
<PAGE>

business combination between the corporation and such stockholder, have been an
interested stockholder but for the inadvertent acquisition of ownership;

            (6) the business combination is proposed prior to the consummation
or abandonment of and subsequent to the earlier of the public announcement or
the notice required hereunder of a proposed transaction which (i) constitutes
one of the transactions described in the second sentence of this paragraph; (ii)
is with or by a person who either was not an interested stockholder during the
previous 3 years or who became an interested stockholder with the approval of
the corporation's board of directors or during the period described in paragraph
(7) of this subsection (b); and (iii) is approved or not opposed by a majority
of the members of the board of directors then in office (but not less than 1)
who were directors prior to any person becoming an interested stockholder during
the previous 3 years or were recommended for election or elected to succeed such
directors by a majority of such directors. The proposed transactions referred to
in the preceding sentence are limited to (x) a merger or consolidation of the
corporation (except for a merger in respect of which, pursuant to Section 251(f)
of the chapter, no vote of the stockholders of the corporation is required); (y)
a sale, lease, exchange, mortgage, pledge, transfer or other disposition (in one
transaction or a series of transactions), whether as part of a dissolution or
otherwise, of assets of the corporation or of any direct or indirect
majority-owned subsidiary of the corporation (other than to any direct or
indirect wholly-owned subsidiary or to the corporation) having an aggregate
market value equal to 50% or more of either that aggregate market value of all
of the assets of the corporation determined on a consolidated basis or the
aggregate market value of all the outstanding stock of the corporation; or (z) a
proposed tender or exchange offer for 50% or more of the outstanding voting
stock of the corporation. The corporation shall give not less then 20 days
notice to all interested stockholders prior to the consummation of any of the
transactions described in clauses (x) or (y) of the second sentence of this
paragraph; or

            (7) The business combination is with an interested stockholder who
became an interested stockholder at a time when the restrictions contained in
this section did not apply by reason of any paragraphs (1) through (4) of this
subsection (b), provided, however, that this paragraph (7) shall not apply if,
at the time such interested stockholder became an interested stockholder, the
corporation's certificate of incorporation contained a provision authorized by
the last sentence of this subsection (b).

            Notwithstanding paragraphs (1), (2), (3) and (4) of this subsection,
a corporation may elect by a provision of its original certificate of
incorporation or any amendment thereto to be governed by this section; provided
that any such amendment to the certificate of incorporation shall not apply to
restrict a business combination between the corporation and an interested
stockholder of the corporation if the interested stockholder became such prior
to the effective date of the amendment.

            (c) As used in this section only, the term:

            (1) "affiliate" means a person that directly, or indirectly through

fiduciary capacity, and (iii) any relative or spouse of such person, or any
relative of such spouse, who has the same residence as such person.

            (3) "business combination," when used in reference to any
corporation and any interested stockholder of such corporation, means:

               (i) any merger or consolidation of the corporation or any direct
or indirect majority -owned subsidiary of the corporation with (A) the
interested stockholder, or (B) with any other corporation, partnership,
unincorporated association or other entity if the merger or consolidation is


                                      B-2
<PAGE>

caused by the interested stockholder and as a result of such merger or
consolidation subsection (a) of this section is not applicable to the surviving
entity;

               (ii) any sale, lease, exchange, mortgage, pledge, transfer or
other disposition (in one transaction or a series of transactions), except
proportionately as a stockholder of such corporation, to or with the interested
stockholder, whether as part of a dissolution or otherwise, of assets of the
corporation or of any direct or indirect majority-owned subsidiary of the
corporation which assets have an aggregate market value equal to 10% or more of
either the aggregate market value of all the assets of the corporation
determined on a consolidated basis or the aggregate market value of all the
outstanding stock of the corporation;

               (iii) any transaction which results in the issuance or transfer
by the corporation or by any direct or indirect majority-owned subsidiary of the
corporation of any stock of the corporation or of such subsidiary to the

outstanding prior to the time that the interested stockholder became such, (B)
pursuant to a merger under Section 251(g) of this title; (C) pursuant to a

to all holders of a class or series of stock of such corporation subsequent to
the time the interested stockholder became such, (D) pursuant to an exchange
offer by the corporation to purchase stock made on the same terms to all holders
of said stock, or (E) any issuance or transfer of stock by the corporation,
provided however, that in no case under (C)-(E) above shall there be an increase
in the interested stockholder's proportionate share of the stock of any class or
series of the corporation or of the voting stock of the corporation;

               (iv) any transaction involving the corporation or any direct or
indirect majority-owned subsidiary of the corporation which has the effect,
directly or indirectly, of increasing the proportionate share of the stock of

otherwise. A person who is the owner of 20% or more of the outstanding voting
stock of any corporation, partnership, unincorporated association or other
entity shall be presumed to have control of such entity, in the absence of proof
by a preponderance of the evidence to the contrary. Notwithstanding the
foregoing, a presumption of control shall not apply where such person holds
voting stock, in good faith and not for the purpose of circumventing this
section, as an agent, bank, broker, nominee, custodian or trustee for one or
more owners who do not individually or as a group have control of such entity.

            (5) "interested stockholder" means any person (other than the
corporation and any direct or indirect majority-owned subsidiary of the
corporation) that (i) is the owner of 15% or more of the outstanding voting
stock of the corporation, or (ii) is an affiliate or associate of the
corporation and was the owner of 15% or more of the outstanding voting stock of
the corporation at any time within the 3-year period immediately prior to the
date on which it is sought to be determined whether such person is an interested
stockholder; and the affiliates and associates of such person; provided,
however, that the term "interested stockholder" shall not include (x) any person
who (A) owned shares in excess of the 15%

limitation set forth herein as of, or acquired such shares pursuant to a tender
offer commenced prior to, December 23, 1987, or pursuant to an exchange offer
announced prior to the aforesaid date and commenced within 90 days thereafter
and either (I) continued to own shares in excess of such 15% limitation or would
have but for action by the corporation or (II) is an affiliate or associate of
the corporation and so continued (or so would have continued but for action by
the corporation) to be the owner of 15% or more of the outstanding voting stock
of the corporation at any time within the 3-year period immediately prior to the
date on which it is sought to be determined whether such a person is an
interested stockholder or (B) acquired said shares from a person described in
(A) above by gift, inheritance or in a transaction in which no consideration was
exchanged; or (y) any person whose ownership of shares in excess of the 15%
limitation set forth herein is the result of action taken solely by the
corporation provided that such person shall be an interested stockholder if
thereafter such person acquires additional shares of voting stock of the
corporation, except as a result of further corporate action not caused, directly
or indirectly, by such person. For the purpose of determining whether a person
is an interested stockholder, the voting stock of the corporation deemed to be
outstanding shall include stock deemed to be owned by the person through
application of paragraph (8) of this subsection but shall not include any other
unissued stock of such corporation which may be issuable pursuant to any
agreement, arrangement or understanding, or upon exercise of conversion rights,
warrants or options, or otherwise.

            (6) "person" means any individual, corporation, partnership,
unincorporated association or other entity.

            (7) "Stock" means, with respect to any corporation, capital stock
and, with respect to any other entity, any equity interest.

            (8) "Voting stock" means, with respect to any corporation, stock of
any class or series entitled to vote generally in the election of directors and,
with respect to any entity that is not a corporation, any equity interest
entitled to vote generally in the election of the governing body of such entity.

            (9) "owner" including the terms "own" and "owned" when used with
respect to any stock means a person that individually or with or through any of
its affiliates or associates:

               (i) beneficially owns such stock, directly or indirectly; or

               (ii) has (A) the right to acquire such stock (whether such right
is exercisable immediately or only after the passage of time) pursuant to any
agreement, arrangement or understanding, or upon the exercise of conversion
rights, exchange rights, warrants or options, or otherwise; provided, however,
that a person shall not be deemed the owner of stock tendered pursuant to a
tender or exchange offer made by such person or any of such person's affiliates
or associates until such tendered stock is accepted for purchase or exchange; or
(B) the right to vote such stock pursuant to any agreement, arrangement or
understanding; provided, however, that a person shall not be deemed the owner of
any stock because of such person's right to vote such stock if the agreement,
arrangement or understanding to vote such stock arises solely from a revocable
proxy or consent given in response to a proxy or consent solicitation made to 10
or more persons; or

               (iii) has any agreement, arrangement or understanding for the
purpose of acquiring, holding, voting (except voting pursuant to a revocable
proxy or consent as described in item (B) of clause (ii) of this paragraph), or
disposing of such stock with any other person that beneficially owns, or whose
affiliates or associates beneficially own, directly or indirectly, such stock.

            (d) No provision of a certificate of incorporation or bylaw shall
require, for any vote of stockholders required by this section a greater vote of
stockholders than that specified in this section.

            (e) The Court of Chancery is hereby vested with exclusive
jurisdiction to hear and determine all matters with respect to this section.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

            Sections 721-725 of the New York Law provide for or permit the
indemnification of directors and officers of TrustCo under certain
circumstances. Generally, a corporation may indemnify a director or officer of
the corporation against any judgments, fines, amounts paid in settlement and
reasonable expenses if such director or officer acted, in good faith, for a
purpose which he reasonably believed to be in the best interests of the
corporation and, in criminal actions, had no reasonable cause to believe that
his conduct was unlawful.

            Article 11 of TrustCo's Certificate provides that, to the fullest
extent elimination or limitation of director liability is permitted by the New
York Law, no director of the corporation shall be liable to the corporation or
its stockholders for any breach of duty in such capacity.

            Article 13, Section 13.2, of the Registrant's Bylaws expressly
provides that no indemnification may be made to or on behalf of any director or
officer if a judgment or other final adjudication adverse to the director or
officer establishes that his acts were committed in bad faith or were the result
of an act of deliberate dishonesty and were material to the cause of action so
adjudicated, or that he personally gained in fact a financial profit or other
advantage to which he was not entitled.

            Pursuant to a policy of directors' and officers' insurance with
total annual limits of $5,000,000, the directors and officers of Registrant
are insured, subject to the limits, exceptions and other terms and conditions
of such policy, against liability for claims made against them for any actual
or alleged error or misstatement or misleading statement or act or omission
or neglect or breach of duty while acting in their individual or collective
capacities as directors or officers.

ITEM 22. UNDERTAKINGS.

            (1) The undersigned Registrant hereby undertakes as follows: 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) promulgated pursuant to the 1933 Act, the issuer undertakes that such
reoffering prospectus will contain the information called for by the applicable
registration form with 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.

            (2) The Registrant undertakes that every prospectus that (i) is
filed pursuant to paragraph (1) immediately preceding, or (ii) purports to meet
the requirements of Section 10(a)(3) of the 1933 Act, and is issued in
connection with an offering of securities subject to Rule 415 promulgated
pursuant to the 1933 Act, 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 1933 Act, each
such post-effective amendment will be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time will be deemed to be the initial bona fide offering thereof.

            (3) Insofar as indemnification for liabilities arising under the
1933 Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions (see Item 20 -- Indemnification
of Directors and Officers), or otherwise, the Registrant has been advised that
in the opinion of the SEC such indemnification is against public policy as
expressed in the 1933 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 of 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 question whether
such indemnification by it is against public policy as expressed in the 1933
Act, and will be governed by the final adjudication of such issue.

            (4) The undersigned Registrant hereby undertakes to deliver or cause
to be delivered with the Prospectus, to each person to whom the Prospectus is
sent or given, the latest annual report to security holders that is incorporated
by reference in the Prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the 1934 Act; and, where interim
financial information required to be presented by Article 3 of Regulation S-X is
not set forth in the Prospectus, to deliver, or cause to be delivered to each
person to whom the Prospectus is sent or given, the latest quarterly report that
is specifically incorporated by reference in the Prospectus to provide such
interim financial information.

            (5) The undersigned Registrant hereby undertakes:

               (a) 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 1933 Act;


                                      II-4
<PAGE>

                   (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;
               notwithstanding the foregoing, any increase or decrease in volume
               of securities offered (if the total dollar value of securities
               offered would not exceed that which was registered) and any
               deviation from the low or high end of the estimated maximum
               offering range may be reflected in the form of prospectus filed
               with the SEC pursuant to Rule 424(b) if, in the aggregate, the
               changes in volume and price represent no more than a 20 percent
               change in the maximum aggregate offering price set forth in the
               "Calculation of Registration Fee" table in the effective
               Registration Statement;

                   (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;

               (b) that, for the purpose of determining any liability under the
1933 Act, each such post-effective amendment 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; and

               (c) 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.

            (6) The undersigned Registrant hereby undertakes that, for purposes
of determining any liability under the 1933 Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or 15(d) of the 1934 Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the 1934 Act), 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.

            (7) 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.

            (8) 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.
