                                       OF
                              COHOES BANCORP, INC.
                                       FOR
                   SHARES OF TRUSTCO BANK CORP NY COMMON STOCK
                                       and
                        $10.80 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
Cohoes Bancorp, Inc. common stock held by you for a combination of shares of
TrustCo common stock and cash totaling $18.00. The stock component of the
exchange consideration will consist of shares of TrustCo stock that have an
aggregate value of $7.20, and the cash component will be $10.80. The purpose of
this offer is for TrustCo to acquire control of, and ultimately the entire
common equity interest in, Cohoes. TrustCo intends, promptly after consummation
of this offer, to have Cohoes consummate a merger with a wholly owned subsidiary
of TrustCo in which each outstanding share of common stock of Cohoes, (except
for treasury shares and shares of Cohoes 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 $7.20 plus cash in the amount of $10.80 for each
share of Cohoes stock.

      We expect that if you realize a gain on the exchange, you will be taxed on
such gain up to the amount of the $10.80 per share cash component of the
consideration that you receive in exchange for your shares of Cohoes 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 Cohoes 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, Hudson River Bancorp, Inc., by offering to exchange
$17.00 in TrustCo common stock and cash for each outstanding share of Hudson
common stock. The TrustCo common stock is listed on the Nasdaq National Market
under the symbol "TRST," the Cohoes common stock is listed on the Nasdaq under
the symbol "COHB" and the Hudson common stock is listed on the Nasdaq under the
symbol "HRBT".

      We have 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 have 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. This exchange offer is
not soliciting proxies from you. We will solicit your proxies pursuant to proxy
solicitation materials that we are mailing separately.

o     Our offer is subject to several conditions, including:

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

              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, Cohoes by first offering to exchange all outstanding
      shares of Cohoes stock for shares of TrustCo stock and cash. Second, we
      intend, promptly after completion of the offer, to merge Cohoes with a
      wholly owned subsidiary of TrustCo. As a result of the TrustCo-Cohoes
      merger, each share of Cohoes 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 Cohoes stock validly tendered and not properly withdrawn
      by you, you will receive a combination of TrustCo stock and cash with an
      aggregate value of $18.00. The stock component of the exchange
      consideration will consist of a number of shares of TrustCo stock having
      an aggregate value of $7.20 (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 $10.80 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 Cohoes' proposed merger with Hudson?

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

Q:    Why should I participate in your offer?

A:    The TrustCo offer is $18.00 in TrustCo stock and cash for each share of
      Cohoes stock. We believe that our proposed offer represents an opportunity
      to enhance value for Cohoes stockholders by providing, among other things:

      o     a premium over the price levels at which we believe Cohoes 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 Cohoes 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 Cohoes 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 COHOES SHARES THAT I TENDER TO YOU?

A:    Yes. Until we accept your shares of Cohoes stock for exchange at the
      completion of our offer, you will be entitled to receive any dividends
      paid on your tendered shares of Cohoes stock and you will continue to have
      the right to vote your tendered shares. Once we complete our offer and
      exchange all shares of Cohoes 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 Cohoes 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 Cohoes 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 Cohoes 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-Cohoes merger.

      o     If required under 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 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:    The timing of completion of this offer will depend on when the
      Hudson-Cohoes merger agreement is terminated. Both Hudson and Cohoes
      currently have the right to terminate the Hudson-Cohoes merger agreement
      because Cohoes' stockholders did not approve the Hudson-Cohoes merger. If
      either Cohoes or Hudson terminates the merger agreement promptly, the
      offer could close in the latter part of the first quarter of 2001. This
      schedule assumes that the Cohoes board of directors promptly cooperates
      with us following termination of the Hudson-Cohoes merger agreement.
      However, the Cohoes board may try to delay our offer. By tendering your
      shares, you will be sending a message to Cohoes management and the Cohoes
      board that you want Cohoes 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 Cohoes stock so that, after completion of
            our offer, we own at least a majority of the outstanding shares of
            Cohoes stock (on a fully diluted basis);

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

      o     the execution of a definitive merger agreement between TrustCo and

            its shareholders;

      o     the receipt of all required regulatory approvals;

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

      o     the effectiveness of the Registration Statement of which this
            Prospectus is a part;

      o     our being satisfied that the provisions of Section 203 of the
            Delaware General Corporation Law and certain anti-takeover
            impediments found in Cohoes' Certificate of Incorporation do not
            apply to or otherwise restrict our offer and the proposed
            TrustCo-Cohoes 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 Cohoes.

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

Q:    WILL I BE TAXED ON THE TRUSTCO SHARES or the cash THAT I RECEIVE?

A:    We expect that if you realize a gain on the exchange, you will be taxed on
      such gain up to the amount of the $10.80 per share cash component of the
      consideration that you receive in exchange for your shares of Cohoes
      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.

Q:    WHO CAN I CALL WITH QUESTIONS ABOUT THE OFFER?

A:    You can contact our information agent, Georgeson Shareholder
      Communications Inc. toll-free at 1-800-223-2064.

      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 Cohoes and Hudson, 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, Cohoes and/or Hudson 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, Cohoes
and Hudson conduct business, may be less favorable than expected; (vii)
legislation or regulatory changes may adversely affect the businesses in which
TrustCo, Cohoes and Hudson 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 Cohoes. For each
share of Cohoes stock tendered and not withdrawn by you, we are offering to
exchange a combination of shares of TrustCo common stock and cash totaling
$18.00. More specifically, you would receive, for each of your Cohoes shares,
TrustCo common stock having a market value of $7.20 (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 $10.80 net in
cash. We intend, promptly after completion of the offer, to merge Cohoes with a
wholly owned subsidiary of TrustCo. Each share of Cohoes 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 Cohoes represents an opportunity to
enhance value for both Cohoes and TrustCo stockholders. Among the benefits that
we believe Cohoes stockholders would obtain from the combination of TrustCo and
Cohoes are the following.

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

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

      o     IMPROVED CASH DIVIDENDS. We anticipate that Cohoes shareholders' pro
            forma dividends will exceed the Cohoes current annual dividend rate.
            The following table shows the pro forma dividend that we would
            anticipate paying to Cohoes shareholders and the amount of the
            increase in that dividend over Cohoes' 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
            Cohoes' current annualized dividend is $0.28 per share. Because the
            actual number of shares of TrustCo common stock that Cohoes'
            stockholders will receive is not yet fixed, the estimated amount of
            cash dividends Cohoes' stockholders will receive will fluctuate with
            the value of TrustCo common stock.

      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 Cohoes'
            stockholders will realize superior performance over Cohoes' 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 Cohoes' common stock.

COMPARATIVE MARKET PRICE INFORMATION

      TrustCo, Cohoes and Hudson common stock trade on the Nasdaq under the

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-Cohoes merger, we expect
to continue paying quarterly cash dividends on a basis consistent with our past


                                       11
<PAGE>



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.

CASH TOTALING $18.00 FOR EACH SHARE OF COHOES 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 $18.00 for each outstanding share of
Cohoes 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 $7.20, and the cash component

pay to Cohoes stockholders in exchange for each share of Cohoes stock assuming

            apply to or otherwise restrict our offer and the proposed
            TrustCo-Cohoes merger; and

      o     if required under the rules of the Nasdaq Stock Market, the approval

            the expiration date, or upon the failure of the condition relating
            to regulatory approvals to be satisfied at any time after the

            exchange or exchanged any shares of Cohoes 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

            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

OFFER TO ACQUIRE HUDSON (PAGE 31)


      On June 8, 2000, TrustCo made an offer to acquire all of the issued and
outstanding shares of Hudson for TrustCo stock valued at $14.00 for each Hudson
share. TrustCo has increased its offer to purchase each Hudson share to $17.00,
consisting of a combination TrustCo stock valued at $6.80 and $10.20 in cash.
TrustCo intends to commence an exchange offer for Hudson on October _____, 2000.
Neither this offer nor the proposed TrustCo-Cohoes merger is conditioned on the
approval or consummation of TrustCo's offer to Hudson.

                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, Cohoes, Hudson, TrustCo/Cohoes combined and
TrustCo/Cohoes/Hudson 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, Cohoes and Hudson for the
six months ended June 30, 2000 and the twelve months ended December 31, 1999 and
similar pro forma information for TrustCo/Cohoes combined and
TrustCo/Cohoes/Hudson combined for the six months ended June 30, 2000. Also
shown, for comparative purposes, is historical net income per share information
for Cohoes for the twelve months ended June 30, 2000 and Hudson for the twelve
months ended March 31, 2000, their most recently reported fiscal year ends.

      The information concerning Cohoes and Hudson 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 Cohoes or Hudson 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 Cohoes and Hudson
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 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.

(3)   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.

(4)   Because the exact exchange ratio of TrustCo stock to Cohoes 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/Cohoes combined, TrustCo/Hudson combined and TrustCo/Cohoes/Hudson
combined.

      The information concerning Cohoes and Hudson 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 Cohoes or Hudson 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 Cohoes and Hudson
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.

NOTE:
The pro forma selected results of operations do not take into consideration any
potential cost savings or revenue enhancements that will likely be realized as a
result of these transactions. TrustCo currently estimates that approximately 50%
of the noninterest expense of Cohoes and Hudson can be eliminated.

                                  RISK FACTORS

      In deciding whether to tender your shares of Cohoes 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 COHOES' OPERATIONS, THE
ANTICIPATED BENEFITS OF THE ACQUISITION OF COHOES 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 Cohoes
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 Hudson 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 $9.0 MILLION on a PRE-TAX basis

      We have estimated that, by combining TrustCo and Cohoes, we could realize
cost savings of approximately $9.0 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 Cohoes and
because we have had no access to Cohoes' internal information about its
operations, in connection with the preparation of our cost savings estimates, we
have relied on publicly available information concerning Cohoes, our general
knowledge of the markets in which we and Cohoes compete and our past experience
with respect to our own operations and our integration of acquired financial
institutions. If we were permitted access to Cohoes' internal information about
its operations or if we were able to discuss our assumptions or analyses with
Cohoes' 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 Cohoes 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 Cohoes' subsidiary, Cohoes Savings Bank, 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 Cohoes and TrustCo.

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

      In formulating our earnings estimates, we have not assumed any net run-off
of revenue attributable to our acquisition of Cohoes. 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 Cohoes from which we would
expect to make such decisions. Accordingly, our earnings estimates do not assume
the closure of any Cohoes (or TrustCo) branches, although we would anticipate
that certain branches will be closed. We believe that any revenue reduction
resulting from any branch closings would be offset by additional cost savings
associated with such branch


                                       26
<PAGE>


closings. If we were permitted access to non-public information regarding
Cohoes' business plans and operations, our assumption of no net revenue run-off
might differ. Although we intend generally to integrate Cohoes' 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 COHOES' 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 Cohoes' senior executive management, and we have no reason to
believe that Cohoes 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 Cohoes' 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 Cohoes
board of directors. See "THE EXCHANGE OFFER--Certain Conditions of the Exchange
Offer." There can be no assurance that the Cohoes 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 Cohoes and HUDSON

      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 Cohoes' security
holders in exchange for shares of Cohoes common stock may be more than or less
than $7.20 per share at the time of exchange

      The actual value of the TrustCo common stock received by Cohoes' security
holders in exchange for shares of Cohoes common stock may be more than or less
than $7.20 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 Cohoes 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


                                       27
<PAGE>


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 COHOES MERGER AND THE HUDSON 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 Cohoes
stockholders will receive is not yet fixed, the estimated amount of cash
dividends Cohoes 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 Cohoes, 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 Cohoes and Hudson 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 Cohoes' and Hudson's assets and liabilities and
the purchase price paid by TrustCo for Cohoes and Hudson. If the transactions
had occurred on June 30, 2000, TrustCo estimates that its acquisitions of Cohoes
and Hudson would have resulted in the creation of goodwill in the amounts of
$24.6 million and $57.0 million, respectively, and that the total amount of
goodwill recorded on TrustCo's financial statements (including the existing
amounts of goodwill on Hudson's and Cohoes' 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 Cohoes' and Hudson's 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,
Cohoes and Hudson was $3.30, $15.13 and $12.33 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-Cohoes merger
occurs, TrustCo's pro forma tangible book value would be $3.56 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 April 25, 2000, Cohoes and Hudson 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 Cohoes and Hudson.

      On June 8, 2000, TrustCo sent a letter to Mr. Duncan MacAffer, the
Chairman of the Board of Cohoes, proposing a 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.

      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 interest of the Hudson and Cohoes shareholders.

      On July 10, 2000, TrustCo sent a letter to Mr. MacAffer, requesting a
meeting to discuss the proposed TrustCo-Cohoes combination. On July 21, 2000,
Cohoes 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 Cohoes and Hudson stockholders against the
proposed Hudson-Cohoes merger .

       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 Cohoes and Hudson in opposition to the proxies solicited by the
management for the August 17, 2000 meetings of the shareholders of Cohoes and
Hudson 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.


                                       29
<PAGE>


      On August 30, 2000, TrustCo sent a letter to Mr. MacAffer and Mr. Harry L.
Robinson, the President and Chief Executive Officer of Cohoes, that outlined the
terms of a potential transaction between TrustCo and Cohoes in advance of a
September 6, 2000 meeting with Cohoes. TrustCo's proposal contemplated an
acquisition of Cohoes by TrustCo at a price of $18.00 per share of Cohoes Common
Stock. At the September 6, 2000 meeting, however, TrustCo declined to proceed
with discussions with Cohoes' representatives in light of the absence from the
meeting of Mr. MacAffer, whose presence TrustCo had requested.

      On September 7, 2000, TrustCo sent a letter to Mr. MacAffer outlining in
more detail the terms of a transaction between TrustCo and Cohoes (including the
$18.00 per share acquisition price) and requesting a response from Cohoes by
September 18, 2000.

      On September 15, 2000, Cohoes requested a meeting with TrustCo, which was
held on September 20, 2000. During this meeting, Cohoes' representatives did not
indicate whether they had any plans to pursue TrustCo's proposals for a
combination with Cohoes or any other similar transactions. Furthermore, Cohoes'
representatives did not provide TrustCo with any timetable for deciding if or
when they will consider the TrustCo proposals or any other proposals. Based upon
these facts, TrustCo determined that further attempts to achieve a negotiated
transaction with Cohoes were unlikely to be successful.

Proxy Solicitation

      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 is
not, with this prospectus, soliciting proxies from Cohoes stockholders. Such a
solicitation of proxies is being made pursuant to proxy solicitation materials
that TrustCo is mailing separately.

PURPOSE OF THE EXCHANGE OFFER; THE TRUSTCO-COHOES MERGER

      The purpose of our offer (the "Exchange Offer") is to acquire control of,
and ultimately the entire equity interest in, Cohoes and to consolidate the
operations of Cohoes and TrustCo to achieve operational efficiencies and cost
savings. TrustCo would not make the Exchange Offer if it could not effect the
TrustCo-Cohoes Merger and, consequently, the Exchange Offer is conditioned upon
the removal of various impediments to consummation of the TrustCo-Cohoes Merger.
As soon as practicable after consummation of the Exchange Offer, TrustCo intends
to cause to occur: (i) the merger of Cohoes with a subsidiary of TrustCo
pursuant to which each outstanding share of Cohoes common stock ("Cohoes 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 $7.20 and $10.80 in cash; and (ii) the integration of
the operations of Cohoes Savings Bank with Trustco Bank, National Association
("Trustco Bank") or another subsidiary of TrustCo.

BENEFITS OF THE TRANSACTION

      Following the TrustCo-Cohoes Merger, TrustCo intends to consolidate all
supervisory functions of Cohoes into TrustCo, transfer all remaining assets of
Cohoes to Trustco Bank and consolidate the business and operations of Cohoes
Savings Bank into Trustco Bank, resulting in operational efficiencies and cost
savings.

      TrustCo believes that the integration of Trustco Bank and Cohoes Savings
Bank will provide increased opportunities for growth and diversification in and
service to the market served by each


                                       30
<PAGE>


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-Cohoes 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-Cohoes Merger and
the integration of Trustco Bank with Cohoes Savings Bank are consummated,
TrustCo would be able to achieve pre-tax cost savings of approximately
$5,000,000 in the first year, and an additional $4,000,000 in the second year
following the TrustCo-Cohoes Merger. See "SELECTED PRO FORMA COMBINED FINANCIAL
INFORMATION."

OFFER TO ACQUIRE HUDSON

      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.

       TrustCo solicited Hudson 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 expects to commence its exchange offer for Hudson on October ___,
2000 by mailing a prospectus and the related letter of transmittal to Hudson
stockholders. In the exchange offer, TrustCo would exchange a combination of
shares of TrustCo Common Stock and cash totaling $17.00 for each outstanding
share of Hudson common stock validly tendered and not withdrawn. The stock
component of the Hudson exchange consideration will be comprised of TrustCo
Common Stock with an aggregate value equal to $6.80, and the cash component will
be $10.20 net. If TrustCo's exchange offer is successful, TrustCo intends to
follow the exchange offer with the TrustCo-Hudson 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-Hudson Merger. Promptly after the SEC declares that registration
statement effective, TrustCo intends to file with the SEC proxy materials to be
used for soliciting the approval by TrustCo's stockholders of the issuance of
TrustCo Common Stock in the Hudson exchange offer and the TrustCo-Hudson Merger.

      The consummation of the Hudson 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 Hudson exchange offer
nor the TrustCo-Hudson 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 Cohoes
and continues to pay the same percentage of income in the form of


                                       31
<PAGE>

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 foregoing dividend rates do not
reflect the potential impact of TrustCo's proposed acquisition of Hudson.)

                               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 a combination of shares of TrustCo Common Stock and
cash totaling $18.00 (the "Exchange Consideration") for each outstanding share
of Cohoes Common Stock validly tendered on or prior to the Expiration Date (as
defined herein) and not withdrawn. The stock component of the 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. A tendering Cohoes
shareholder may, by properly completing the Letter of Transmittal, elect to
receive the Exchange Consideration for his or her Cohoes 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 $7.20 per share of Cohoes Common Stock
exchanged, the number of shares of TrustCo Common Stock that a tendering Cohoes
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 Cohoes 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."

      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 Cohoes 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


                                       32
<PAGE>


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 Cohoes 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 Cohoes 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 Cohoes Common Stock; or (iii)
terminate the Exchange Offer and exchange none of the Cohoes Common Stock and
return all tendered shares of Cohoes Common Stock. TrustCo will not accept for
exchange any shares of Cohoes 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 Cohoes for use of Cohoes' shareholder list and
security position listing for the purpose of disseminating the Exchange Offer to
holders of Cohoes Common Stock. The Prospectus and the related Letter of
Transmittal will be mailed to record holders of Cohoes 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 Cohoes 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
Cohoes 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 Cohoes Common Stock. See "THE EXCHANGE OFFER -- Withdrawal Rights."
TrustCo also reserves the right to delay acceptance for exchange of, or exchange
of, any Cohoes Common Stock pursuant to the Exchange Offer, regardless of
whether such shares of Cohoes Common Stock were theretofore accepted for
exchange, and to amend or terminate the Exchange Offer and not accept for
exchange or exchange any Cohoes 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


                                       33
<PAGE>

Cohoes Common Stock, such increase will be applicable to all holders whose
shares of Cohoes 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 Cohoes 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 Cohoes
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 Cohoes 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 Cohoes 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 Cohoes Common Stock. Delivery of the
Exchange Consideration in exchange for the Cohoes 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 Cohoes 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 Cohoes Common Stock
than are tendered, certificates for such un-exchanged Cohoes Common Stock will
be returned to the tendering Cohoes shareholder by the Exchange Agent as soon as
practicable following consummation or termination of the Exchange Offer.



ADDITIONAL 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 Cohoes 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 Cohoes 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 Cohoes Common
Stock to be withdrawn, the number of shares of Cohoes Common Stock to be
withdrawn and the name of the registered holder, if different from that of the
person who tendered such shares of Cohoes Common Stock.


                                       34
<PAGE>

      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 Cohoes 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 Cohoes 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 Cohoes Common
Stock properly withdrawn will be deemed not to have been validly tendered for
purposes of the Exchange Offer. However, withdrawn shares of Cohoes 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 Cohoes 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 Cohoes 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 Cohoes Common Stock are tendered by a
registered holder of Cohoes 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 Cohoes 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 Cohoes Common Stock tendered
by such shareholder and accepted for exchange by TrustCo and with respect to any
and all other shares of Cohoes Common Stock and other securities issued or
issuable in respect of the Cohoes Common Stock on or after ____________________,
2000. Such appointment will be effective when, and only to the extent that,
TrustCo exchanges the Exchange Consideration for Cohoes 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 Cohoes Common Stock as they in their sole
discretion deem proper at any annual, special or adjourned meeting of Cohoes'
shareholders or otherwise. TrustCo reserves the right to require that, in order
for shares of Cohoes Common Stock to be deemed validly tendered, immediately
upon TrustCo's exchange of such Cohoes Common Stock TrustCo must be able to
exercise full voting rights with respect to such shares of Cohoes Common Stock.

      If a shareholder desires to tender shares of Cohoes 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:


                                       35
<PAGE>

(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 Cohoes 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 Cohoes 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 Cohoes 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 Cohoes Common Stock. No tender of
Cohoes 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 Cohoes Common
Stock or will incur any liability for failure to give any such notification.

      A tender of Cohoes 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 Cohoes Common Stock for TrustCo Common Stock pursuant to the
Exchange Offer and the TrustCo-Cohoes 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
Cohoes Common Stock, except as described below under "Tax Consequences to Cohoes
Shareholders if the Exchange Offer and the TrustCo-Cohoes 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-Cohoes Merger should be treated as
a single transaction and on certain assumptions and representations, including
that: (i) each Cohoes shareholder holds his or her shares of Cohoes 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


                                       36
<PAGE>

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 Cohoes Common Stock
prior to the consummation of the Exchange Offer) will be satisfied; (iii)
TrustCo will continue Cohoes' historic business or will use a significant
portion of Cohoes' historic business assets in a business; (iv) the Exchange
Offer and the TrustCo-Cohoes Merger will be consummated as contemplated by this
Prospectus; and (vi) there are valid business reasons for undertaking the
Exchange Offer and the TrustCo-Cohoes 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-Cohoes 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-Cohoes Merger; and (iii) the TrustCo-Cohoes Merger
will in fact be consummated promptly after the consummation of the Exchange
Offer. A significant delay in the consummation of the TrustCo-Cohoes 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-Cohoes 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-Cohoes 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 Cohoes. This summary
does not address all aspects of federal taxation that may be relevant to
particular Cohoes 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 Cohoes Common Stock
pursuant to an exercise of employee stock options or rights or otherwise as
compensation and persons who hold shares of Cohoes 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-Cohoes Merger. An opinion of
counsel is not binding on the IRS, and the IRS is not precluded from taking
contrary positions.

      COHOES 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.


                                       37
<PAGE>

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

      In order for the Exchange Offer and the TrustCo-Cohoes Merger to qualify
as a reorganization under the Code, it is necessary that Exchange Offer and the
TrustCo-Cohoes 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-Cohoes Merger and, consequently, has
conditioned its obligation to accept shares of Cohoes Common Stock under the
Exchange Offer by requiring the elimination of various impediments to
consummation of the TrustCo-Cohoes Merger. See "THE EXCHANGE OFFER--Certain
Conditions of the Exchange Offer--Removal of Impediments Condition." Thus,
TrustCo views the Exchange Offer and the TrustCo-Cohoes Merger as interdependent
parts of a single transaction. For federal income tax purposes, the IRS should
treat the Exchange Offer and the TrustCo-Cohoes 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-Cohoes Merger together
should qualify as a reorganization for federal income tax purposes and a Cohoes
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 Cohoes 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 Cohoes shareholder's holding
period for the Cohoes 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 Cohoes
shareholder, including for this purpose any fractional share of TrustCo Common
Stock for which cash is received, in exchange for Cohoes Common Stock pursuant
to the Exchange Offer and the TrustCo-Cohoes Merger generally will equal that
shareholder's aggregate tax basis of his Cohoes Common 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
Cohoes Common Stock surrendered in exchange therefor, provided that the such
shares of Cohoes Common Stock are held as capital assets at the time of the
Exchange Offer and TrustCo-Cohoes Merger.

      In general, the determination of whether the gain recognized by a Cohoes
shareholder will be treated as capital gain or a dividend distribution will
depend upon whether and to what extent the exchange reduced the Cohoes
shareholder's deemed percentage stock ownership interest in TrustCo. For
purposes of this determination, a Cohoes shareholder will be treated as if such
shareholder first exchanged all of such shareholder's Cohoes 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 Cohoes 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 Cohoes 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



                                       38
<PAGE>

TrustCo that such Cohoes 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 Cohoes 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 Cohoes 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 Cohoes 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 Cohoes 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
Cohoes 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 Cohoes shareholder's holding period in the Cohoes Common Stock exchanged
was greater than one year as of the date of the exchange.



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

      If the TrustCo-Cohoes Merger is not consummated or is consummated in a way
that causes the Exchange Offer and the TrustCo-Cohoes Merger not to be a
"reorganization," or if the TrustCo-Cohoes 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-Cohoes 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 Cohoes Common Stock
will recognize gain or loss for federal income tax purposes measured by the
difference between such shareholder's basis in the Cohoes 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 Cohoes Common Stock were held as a capital
asset and will be long-term gain or loss if such Cohoes Common Stock had been
held for more than one year at the time of the exchange.

      Exchanges pursuant to the TrustCo-Cohoes 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-Cohoes Merger itself might be considered a reorganization. In that
event, a shareholder of Cohoes 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-Cohoes Merger (but not with respect to any TrustCo Common Stock and
cash received by such shareholder in the Exchange Offer).

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

EFFECT OF EXCHANGE OFFER ON MARKET FOR SHARES

      As of September 1, 2000, according to Cohoes' Annual Report on Form 10-K
for the year ended June 30, 2000, there were 7,912,705 shares of Cohoes Common
Stock outstanding.



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

      Cohoes 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 Cohoes Common Stock, and the availability of price
quotations, will depend upon the number of holders, the aggregate market value
of the Cohoes Common Stock remaining, the interest of securities firms in
maintaining a market in the Cohoes 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 Cohoes
shareholder who may be deemed to be an "affiliate" of Cohoes 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 Cohoes. Persons who may be
deemed to be "affiliates" of Cohoes generally include individuals who, or
entities that, control, are controlled by or are under common control with
Cohoes, and may include certain officers and directors of Cohoes as well as
principal shareholders of Cohoes.

CERTAIN LEGAL MATTERS

      GENERAL

      Except as set forth below, based upon an examination of publicly available
information filed by Cohoes with the SEC and other publicly available
information with respect to Cohoes, TrustCo is not aware of any license or
regulatory permit which appears to be material to the business of Cohoes and
which is likely to be adversely affected by TrustCo's acquisition of Cohoes
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 Cohoes
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
Cohoes 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-Cohoes
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 Cohoes 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 Cohoes
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."

                                       40
<PAGE>

      FEDERAL REGULATORY MATTERS

      The acquisition of Cohoes Common Stock pursuant to the Exchange Offer (the
"Acquisition") and the consummation of the TrustCo-Cohoes 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-Cohoes
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 Cohoes; (iii) the convenience and needs of the
community served by TrustCo and Cohoes; 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-Cohoes 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
Cohoes 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.

      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 Cohoes 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 Cohoes 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 Cohoes received C.R.A. ratings of satisfactory, and
outstanding 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

                                       41
<PAGE>

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 Cohoes 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.

      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 Cohoes Common
Stock which, together with the shares of Cohoes Common Stock beneficially owned
by TrustCo and its affiliates for their own respective accounts, would represent
at least a majority of the Cohoes Common Stock outstanding on a fully diluted
basis (i.e., as though all options or other securities convertible into or
exercisable for shares of Cohoes Common Stock had been so converted, exercised
or exchanged) on the date shares of Cohoes Common Stock are accepted by TrustCo
pursuant to the Exchange Offer (the "Minimum Tender Condition"). According to
Cohoes' Annual Report on Form 10-K for the year ended June 30, 2000, there were
7,912,705 shares of Cohoes Common Stock outstanding on September 1, 2000 and,
according to Cohoes' proxy statement for its August 17, 2000 special meeting of
shareholders ("Cohoes Proxy Statement"), there were 1,334,931 shares of Cohoes
Common Stock in the aggregate reserved for issuance pursuant to the Cohoes Stock
Option and Incentive Plan and the Cohoes Recognition and Retention Plan as of
June 22, 2000. Based on the foregoing, TrustCo believes that the Minimum Tender
Condition would have been satisfied on June 22, 2000 if, in addition to the
100,000 shares of Cohoes Common Stock currently owned beneficially by TrustCo
and its affiliates for their own respective accounts, at least an aggregate of
3,856,353 shares of Cohoes Common Stock outstanding on September 1, 2000, in
addition to shares of Cohoes Common Stock in an amount at least equal to 50.1%
of any outstanding options to acquire Cohoes 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 the Minimum Tender Condition on or before the


                                       42
<PAGE>

Expiration Date and to purchase fewer than such number of shares of Cohoes
Common Stock as would satisfy the Minimum Tender Condition pursuant to the
Exchange Offer.

      REGULATORY APPROVAL CONDITION

      The Exchange Offer and the TrustCo-Cohoes 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

      Cohoes' Certificate of Incorporation (the "Cohoes 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 Cohoes entitled to vote in the election of
directors. Generally, an interested stockholder is any person, other than Cohoes
or any subsidiary of Cohoes, that is the beneficial owner, directly or
indirectly, of more than 10% of the voting power of the outstanding voting stock
of Cohoes. 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 Cohoes or any subsidiary of Cohoes
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 Cohoes entitled to
vote in the election of directors, if the business combination has been approved
by a majority of the disinterested directors of Cohoes, the fair market value of
the consideration received per share by the holders of Cohoes 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 Cohoes prior to consummation of the business
combination, and 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 Cohoes at least 30 days prior to the consummation
of such business combination. Cohoes' Certificate also provides that, with
certain exceptions, a beneficial owner of more than 10% of the voting stock of
Cohoes is prohibited from voting more than 10% of the stock of Cohoes (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 Cohoes (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 Cohoes' 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 Cohoes 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


                                       43
<PAGE>

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. Cohoes'
Certificate does not exempt Cohoes from the requirements of Section 203. A copy
of Section 203 is attached hereto as Appendix B.

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

      All of the above are impediments to the consummation of the TrustCo-Cohoes
Merger. The Exchange Offer is subject to the condition (the "Removal of
Impediments Condition") that TrustCo is not required to exchange shares of
Cohoes 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 Cohoes Board approves the
Exchange Offer and the Cohoes Board and Cohoes shareholders (by a majority vote
of the outstanding shares of Cohoes stock) approve the TrustCo-Cohoes Merger; or
(ii) TrustCo being satisfied, in its reasonable discretion, that Section 203 and
the anti-takeover provisions of Cohoes' Certificate of Incorporation and the
charter of Cohoes Savings Bank are invalid or are not applicable to the
transactions contemplated by the Exchange Offer and the TrustCo-Cohoes Merger.
The consideration offered pursuant to the Exchange Offer meets the fair price
requirements of the business combination provisions of Cohoes' Certificate and,
except for the required approval of Cohoes' directors and shareholders,
satisfaction of the other conditions would be within TrustCo's control.
Accordingly, the approval of the Exchange Offer and the TrustCo-Cohoes Merger by
the Cohoes Board (other than any director nominated by TrustCo and thereafter
elected to the Cohoes Board) would obviate the 80% vote requirement of Cohoes'
Certificate and also make Section 203 inapplicable to the transaction. As part
of its approval of the TrustCo-Cohoes Merger, the Cohoes Board would also have
to: (a) make appropriate arrangements for amendment to the charter of Cohoes
Savings Bank to eliminate the 10% or greater ownership prohibition contained
therein; and (b) call a meeting of shareholders of Cohoes to approve the
TrustCo-Cohoes Merger.

      The exact timing and details of the closing of the TrustCo-Cohoes Merger
between TrustCo and Cohoes following the Exchange Offer will necessarily depend
upon a variety of factors, including the means and methods employed by the
Cohoes Board in approving, and causing to be held a meeting of Cohoes
shareholders for the purpose of approving, the TrustCo-Cohoes Merger. Although
TrustCo intends to propose and to seek consummation of the TrustCo-Cohoes 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 Cohoes 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


                                       44
<PAGE>

Common Stock to be issued in the Exchange Offer and the TrustCo-Cohoes 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-Cohoes Merger will exceed 20% of
the currently outstanding number of shares, changes in the price of TrustCo
Common Stock or a determination that the TrustCo Common Stock 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 rules of the Nasdaq Stock Market
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-Cohoes 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 Cohoes. 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 in
      existence on or prior to June 30, 1999: (i) seeking to obtain any material
      damages from Cohoes; (ii) seeking to prohibit or restrict Cohoes'
      ownership or operation of any material portion of its business or assets,
      or to compel Cohoes to dispose of or hold separate all or any material
      portion of Cohoes' business or assets; (iii) which otherwise is reasonably
      likely to materially adversely affect Cohoes or the value of the Cohoes
      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 Cohoes Common Stock, including, without limitation, the
      right to vote the shares of Cohoes Common Stock acquired by it on all
      matters properly presented to the stockholders of Cohoes 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-Cohoes 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 Cohoes
      (including, without limitation, the disposition of assets) which, in the
      reasonable judgment of TrustCo, is or may be materially adverse to Cohoes
      or to the value of the Cohoes 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 Cohoes or any of its
      subsidiaries or to the value of the Cohoes Common Stock; and


                                       45
<PAGE>

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 Hudson to
Cohoes of the options granted to Hudson thereunder. The Hudson-Cohoes Option
Agreement was entered into in connection with the Hudson-Cohoes Merger
Agreement. Under the Hudson-Cohoes Option Agreement, Cohoes granted Hudson an
unconditional, irrevocable option to purchase up to 1,574,538 shares of Cohoes
Common Stock at a price per share of $9.8125.

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

      Hudson 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) Cohoes, without Hudson's prior consent, enters into an
agreement to be acquired (i.e., 10% or more of the voting power of the Cohoes
Common Stock), or the Cohoes Board recommends that the Cohoes shareholders
approve such an acquisition transaction with any person other than Hudson; (ii)
any person other than Hudson acquires beneficial ownership (or the right to
acquire beneficial ownership) of 10% or more of the outstanding shares of Cohoes
Common Stock; (iii) any person publicly announces that it has made or intends to
make a proposal to engage in an acquisition transaction with Cohoes; (iv) the
Cohoes Board (without having received Hudson's consent): (a) withdraws its
recommendation to the Cohoes 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 Hudson; or (c) provides
information to or engages in negotiations with a third party relating to a
possible acquisition transaction; (v) any person (other than Hudson) 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) Cohoes willfully breaches any covenant or obligation contained in the
Hudson-Cohoes Merger Agreement after an overture is made by a third party to
Cohoes or its shareholders to engage in a possible acquisition transaction and
such breach would entitle Hudson 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 Hudson and without Hudson's
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-Cohoes Merger, constitute an "Initial Triggering Event."

      A "Subsequent Triggering Event" means: (i) the acquisition by any person
(other than Hudson) of beneficial ownership of 25% or more of the outstanding
Cohoes 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-Cohoes Merger, will constitute a
"Subsequent Triggering Event."


                                       46
<PAGE>

      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-Cohoes Merger will constitute a Subsequent
Triggering Event, Cohoes and Hudson will need to mutually agree to terminate the
Hudson-Cohoes Option Agreement to satisfy this condition.

      DEFINITIVE TRUSTCO-COHOES MERGER AGREEMENT

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

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 Cohoes 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-Cohoes
Merger will be, included for quotation on the Nasdaq.

SOURCE OF FUNDS

      The cash portion of the Exchange Consideration, i.e. the $10.80 net in
cash and the amounts necessary for payments in lieu of fractional shares, will
be funded from TrustCo's existing cash assets and/or an advance from Trustco
Bank to TrustCo.

TREATMENT OF COHOES STOCK OPTIONS

      Cohoes 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-Cohoes Merger and the holder thereof will receive from TrustCo, in
payment for such option, cash equal to $18.00 less the exercise price of the
stock option. Any resulting fractional shares will also 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, Cohoes announced that its shareholders
failed to approve the Hudson-Cohoes Merger.

TERMINATION OF MERGER AGREEMENT AND AMENDMENT TO OPTION

      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 company should any third party pursue
a transaction with Hudson or Cohoes. Hudson and Cohoes publicly announced that
the amendment capped the economic value of their respective stock options in
each other at $3.5 million.

COHOES EXPLORATION OF STRATEGIC ALTERNATIVES

      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.

      Cohoes announcement did not indicate whether the Cohoes board had
considered the $18.00 per share price proposed by TrustCo in its August 30, 2000
and September 7, 2000 letters or whether the board had determined that the
$18.00 price was inadequate.

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.

               UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

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


                                       49

      TrustCo has not had access to the Cohoes or Hudson records as part of its
attempt to allocate the cost of its investment in the fair values of the Cohoes
and Hudson 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 Cohoes and Hudson 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 Cohoes or Hudson amounts and has not performed any procedures to
ensure their accuracy or reasonableness. Certain Cohoes and Hudson 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
Cohoes and Hudson 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 Stock
issued and outstanding, and no shares of the preferred stock are issued or
outstanding.



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.

      TRANSFER AGENT

      Trustco Bank is the transfer agent for shares of TrustCo Common Stock.

                                       66
<PAGE>


PREFERRED STOCK

      None of the 500,000 authorized shares of preferred stock of TrustCo are
issued. The TrustCo Board is authorized to issue the preferred stock and to fix
and state voting powers, designations, preferences or other special rights 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.

                       DESCRIPTION OF COHOES' CAPITAL STOCK

GENERAL

      The following description of Cohoes' capital stock is based on information
contained in the Annual Report on Form 10-K of Cohoes for the year ended June
30, 1999 and other public information available on Cohoes, including Cohoes'
Proxy Statement.

      Cohoes is authorized to issue 25,000,000 shares of common stock, par value
$.01 per share (referred to in this Prospectus as "Cohoes Common Stock"), and
5,000,000 shares of preferred stock, par value $.01 per share. At June 22, 2000,
there were 7,912,255 shares of Cohoes Common Stock issued and outstanding and no
shares of the preferred stock were issued and outstanding.

COMMON STOCK

      The holders of shares of Cohoes Common Stock are entitled to receive
dividends from funds legally available therefor when, as and if declared by the
Cohoes Board, and are entitled upon liquidation to receive pro rata the net
assets of Cohoes after satisfaction in full of the prior rights of creditors of
Cohoes and holders of any shares of preferred stock.

      The holders of shares of Cohoes Common Stock are generally entitled to one
vote for each share of Cohoes Common Stock held on all matters as to which
stockholders are entitled to vote, subject to the 10% Limit. The holders of
Cohoes Common Stock do not have cumulative voting rights.

      American Stock Transfer & Trust Company, 40 Wall Street, New York, NY
10005 is the transfer agent and registrar for the shares of Cohoes Common Stock.

PREFERRED STOCK

      None of the 5,000,000 authorized shares of preferred stock of Cohoes are
issued. The Cohoes Board is authorized to issue the preferred stock from time to
time in one or more series with such designation, powers, preferences and
rights, including voting rights, and any qualifications, limitations or
restrictions thereof, as may determined by the Cohoes Board. 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.

                         COMPARISON OF SHAREHOLDER RIGHTS

      The rights of holders of Cohoes Common Stock who receive TrustCo Common
Stock in the Exchange Offer will be governed by the New York Law, the state in
which TrustCo is incorporated, and by TrustCo's Amended and Restated Certificate
of Incorporation, as amended ("TrustCo's Certificate"), and Bylaws, as amended,
and other corporate documents of TrustCo. The rights of holders of Cohoes Common
Stock, which are governed by the DGCL and Cohoes' 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 Cohoes and TrustCo stockholders is set forth below.

                                       67

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.

            COHOES

      Cohoes' Certificate provides for a greater than majority stockholder
approval requirement for certain business combinations with interested
stockholders. Under Cohoes' 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 Cohoes entitled to
vote in the election of directors. Generally, an interested stockholder is any
person, other than Cohoes or any subsidiary of Cohoes, that is the beneficial
owner, directly or indirectly, of more than 10% of the voting power of the
outstanding voting stock of Cohoes. 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 Cohoes or any subsidiary of Cohoes
with an interested stockholder or affiliate thereof; (ii) any sale, lease,
exchange, mortgage, pledge, transfer or other disposition of assets of Cohoes or
any Cohoes subsidiary to an interested stockholder having an aggregate fair
market value equaling or exceeding 25% or more of the combined assets of Cohoes
and its subsidiaries; (iii) the purchase, exchange, lease or other acquisition
by Cohoes or any subsidiary of all or substantially all of the assets or
business of an interested stockholder or affiliate thereof; (iv) the issuance or
transfer by Cohoes or any subsidiary of Cohoes to an interested stockholder or
affiliate thereof of any securities of Cohoes or any subsidiary of Cohoes having
an aggregate fair market value equaling or exceeding 10% of the combined fair
market value of the outstanding common stock of Cohoes and its subsidiaries; (v)
the adoption of any plan for the liquidation or dissolution of Cohoes proposed
by or on behalf of an interested stockholder or affiliate thereof; and (vi) any
reclassification of securities or recapitalization of Cohoes, or any merger or
consolidation of Cohoes 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 Cohoes or any
subsidiary of

                                       68
<PAGE>


Cohoes directly or indirectly owned by an interested stockholder or affiliate
thereof. 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 Cohoes 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 Cohoes
solely in their capacity as stockholders of Cohoes and the business combination
has been approved by a majority of the disinterested directors of Cohoes; or (b)
the business combination has been approved by a majority of the disinterested
directors of Cohoes, or each of the following conditions are met: (1) the fair
market value of the consideration received per share by the holders of Cohoes
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 Cohoes 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 Cohoes
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.

            COHOES

      Cohoes' Certificate provides that any director or the entire Cohoes 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 Cohoes entitled to vote generally in the election of directors.
Cohoes' 80% stockholder vote requirement for removal of directors precludes a
majority stockholder from circumventing Cohoes' classified Cohoes Board by
decreasing the size of the Cohoes 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 Cohoes Board.
Stockholders of Cohoes may not remove directors without cause, making it more
difficult for a majority stockholder to control the Cohoes Board. The
restriction on director removal found in Cohoes' Certificate also makes it more
difficult for stockholders of Cohoes to change the composition of the Cohoes
Board even where the stockholders believe in good faith that such a change would
be beneficial to Cohoes and to the stockholders of Cohoes.

      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.

            COHOES

      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

                                       69
<PAGE>


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

      Cohoes' Certificate provides that Cohoes may amend or repeal any provision
contained in Cohoes' Certificate in the manner prescribed described above
pursuant to the DGCL. Cohoes' 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 Cohoes 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 --
COHOES") is required to amend or repeal the provisions of: (i) Article TWELFTH
(relating to amending the Cohoes' Certificate); (ii) Section C of Article FOURTH
(relating to voting restrictions imposed on stockholders owning in excess of 10%
of the outstanding shares of Cohoes 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 Cohoes); (v) Article SEVENTH (relating to amending the
Bylaws); (vi) Article EIGHTH (relating to approval of business combinations with
an interested stockholder or its affiliates); and (vii) Article TENTH (relating
to indemnification).

      Cohoes' Bylaws provide that the Cohoes Board may amend or repeal the
Bylaws upon the vote of a majority of the whole board thereof. The stockholders
of Cohoes, 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 Cohoes.

      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 must be
approved by the affirmative vote of at least a majority of the outstanding
shares of TrustCo Common Stock, except those matters specifically requiring a
greater than majority vote pursuant to the New York Law or TrustCo's
Certificate.

            COHOES

      In accordance with the DGCL, and as provided in the Bylaws of Cohoes, each
outstanding share of Cohoes Common Stock is entitled to one vote on each matter
voted on at a stockholders' meeting. A stockholder of Cohoes may vote in person
or by proxy. Directors of Cohoes are elected by a plurality of the stockholder
votes cast, and stockholders of Cohoes 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
Cohoes' Certificate. Notwithstanding the foregoing, Article FOURTH, Section C,
of Cohoes' Certificate provides that no person who beneficially owns more than
10% of the outstanding shares of Cohoes Common Stock may vote shares in excess
of that limit. See "COMPARISON OF SHAREHOLDER RIGHTS -- Anti-Takeover Statutes
and Provisions -- COHOES."

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.

      COHOES

      In accordance with the DGCL, Cohoes' Certificate provides that special
meetings of stockholders of Cohoes may be called only by the Cohoes Board
pursuant to a resolution adopted by a majority of the total number of directors
which Cohoes would have if there were no vacancies on the Cohoes Board. Cohoes'
Certificate also provides that any action required or permitted to be taken by
the stockholders of Cohoes 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. Cohoes' 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. Cohoes' more restrictive
provisions preclude attempts by stockholders to disrupt the business of Cohoes
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 Cohoes Board and management of Cohoes. Cohoes' 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 Cohoes 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.

      COHOES

      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>


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

      COHOES

      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 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.

                                       72
<PAGE>

      Under the terms of Cohoes' Certificate, a record owner of Cohoes Common
Stock who beneficially owns, directly or indirectly, in excess of 10% of the
outstanding shares of Cohoes Common Stock is not entitled to vote the shares
held in excess of 10% of the outstanding shares of Cohoes 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 Cohoes 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 Cohoes Common Stock
beneficially owned by such person owning shares in excess of the 10% Limit.

      As with TrustCo, Cohoes' Certificate provides that the Cohoes 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 -- COHOES", and "-- Stockholder Vote Required for Certain
Transactions -- REMOVAL OF DIRECTORS -- COHOES."

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.

      COHOES

      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. Cohoes'
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 Cohoes or a subsidiary of Cohoes or is or was serving at the request of
Cohoes 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. Cohoes' Certificate provides indemnification
to an indemnitee who initiates a proceeding only if the proceeding was
authorized by the Cohoes Board or was initiated to enforce indemnification
rights. Cohoes' Certificate provides for payment of indemnification expenses in
advance of a proceeding's final disposition provided the indemnitee first
delivers to Cohoes 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, Cohoes may in accordance with Cohoes' Certificate, to the
extent authorized by the Cohoes Board, grant rights to indemnification and to
the advancement of indemnification expenses to any employee or agent of Cohoes
to the fullest extent that Cohoes is authorized to indemnify and advance
expenses to the directors and officers of Cohoes. Cohoes' Certificate also
authorizes Cohoes to maintain insurance to protect Cohoes and any director,
officer, employee or agent of Cohoes or another corporation against any expense,
liability or loss, whether or not Cohoes 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.

      COHOES

      Cohoes' Certificate provides that a director of Cohoes will not be
personally liable to Cohoes or the stockholders of Cohoes 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 Cohoes or the stockholders
of Cohoes; (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 Cohoes 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
Cohoes. Cohoes' 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. Cohoes' 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 Cohoes 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.

      COHOES

      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 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.

      Cohoes' Certificate grants the Cohoes Board broader discretion than that
authorized by Delaware case law. Specifically, Cohoes' Certificate provides that
the Cohoes Board may, when evaluating any tender or exchange offer, any offer to
merge or consolidate Cohoes with another entity or any offer to purchase all or
substantially all of the assets of Cohoes, 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
Cohoes and subsidiaries of Cohoes, the communities in which Cohoes and its
subsidiaries operate or are located, and the ability of Cohoes 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

Shares), are received by the Exchange Agent. The undersigned further

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.

                                   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 one or

      (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
interested stockholder, except (A) pursuant to the exercise, exchange or
conversion of securities exercisable for, exchangeable for or convertible into
stock of such corporation or any such subsidiary which securities were
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
dividend or distribution paid or made, or the exercise, exchange or conversion

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
any class or series, or securities convertible into the stock of any class or
series, of the corporation or of any such subsidiary which is owned by the
interested stockholder, except as a result of immaterial changes due to
fractional share adjustments or as a result of any purchase or redemption of any
shares of stock not caused, directly or indirectly, by the interested
stockholder; or

            (v) any receipt by the interested stockholder of the benefit,
directly or indirectly (except proportionately as a stockholder of such
corporation) of any loans, advances, guarantees, pledges, or other financial
benefits (other than those expressly permitted in subparagraphs (i)-(iv) above)
provided by or through the corporation or any direct or indirect majority owned
subsidiary.

person, whether through the ownership of voting stock, by contract, or
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

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%

                                      B-3
<PAGE>

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. (Last amended by
Ch. 79, L. `95, eff. 7-1-95.)

                      INFORMATION NOT REQUIRED IN PROSPECTUS

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.

      99          Section 203 of the DGCL (Appendix B to this Prospectus)


      *  Previously filed.

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) 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


                                      II-4
<PAGE>

            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.
