Dear Cohoes Bancorp Shareholder:

     Following is a Proxy Statement  explaining why we are proposing  candidates
in opposition  to the slate  proposed by  management,  and have taken a position
against the  approval  of the  amendments  to the Cohoes  1999 Stock  Option and
Incentive Plan and the 1999 Recognition and Retention Plan.

     We believe  that our  positions  provide  the best  opportunity  for Cohoes
shareholders to maximize shareholder value.

     We urge you to vote soon, using the materials provided in this mailing.




Sincerely,


/s/Robert A. McCormick

Robert A. McCormick
President and Chief Executive Officer




                                 PROXY STATEMENT
                                       OF
                              TRUSTCO BANK CORP NY

                       IN OPPOSITION TO THE MANAGEMENT OF
                              COHOES BANCORP, INC.

            2000 Annual Meeting of Cohoes Bancorp, Inc. Stockholders

          *PLEASE SIGN, DATE AND RETURN THE ENCLOSED WHITE PROXY CARD*

     This  proxy  statement  and the  accompanying  white  proxy  card are being
furnished to  stockholders of Cohoes  Bancorp,  Inc.  ("Cohoes") by TrustCo Bank
Corp NY, a New York corporation ("TrustCo"), in connection with the solicitation
of proxies  from  Cohoes  stockholders  which are to be used at the 2000  Annual
Meeting  of  Stockholders  (the  "Annual  Meeting")  of  Cohoes,  including  any
adjournments, postponements or reschedulings thereof. The Cohoes' Annual Meeting
will be held at the Cohoes Community Center,  22-40 Remsen Street,  Cohoes,  New
York, on Thursday,  November 30, 2000, at 4:00 p.m.  Stockholders  as of October
19,  2000 (the  "Record  Date") will be entitled to notice of and to vote at the
Annual  Meeting.  Stockholders  of record at the close of business on the Record
Date will be entitled  to one vote for each share of Cohoes  common  stock,  par
value $.01 per share, held on the Record Date. TrustCo, together with all of the
participants in this  solicitation,  beneficially  owns 100,000 shares of Cohoes
common stock, representing 1.3% of the total Cohoes common stock outstanding and
entitled  to vote at the  Annual  Meeting.  As of the  Record  Date,  Cohoes had
7,912,705 shares of common stock outstanding.

     Based upon information contained in Cohoes' Annual Meeting proxy statement,
at the Annual  Meeting,  Cohoes  stockholders  will  consider  and vote upon the
following matters:

          1. The election of four directors, each to serve for a three-year term
             of office;

          2. To amend the Cohoes 1999 Stock  Option and  Incentive  Plan and the
             Cohoes  1999  Recognition  and  Retention  Plan to  revise  the
             provisions relating to the vesting of options and restricted stock
             awards; and

          3. The ratification of the appointment of Arthur Andersen LLP as
             Cohoes' independent public accountants.

     We believe that the actions of Cohoes'  current  Board of  Directors,  most
recently the unsuccessful attempt to merge with Hudson River Bancorp, Inc., call
into  question  whether the  current  Board of  Directors  is acting in the best
interests of all Cohoes  stockholders.  TrustCo is soliciting  proxies to obtain
representation   on  the   Cohoes   Board,   and  to   demonstrate   stockholder
dissatisfaction  with  recent  actions  of the  Cohoes  Board of  Directors  and
management,  including,  in  particular,  (i) the failure by the Cohoes Board of
Directors to consider  TrustCo's  proposal to acquire Cohoes at a  significantly
higher  price  than that  offered to Cohoes  stockholders  as part of the failed
Cohoes-Hudson  River  Bancorp  merger,  and (ii) the Cohoes  Board of  Directors
decision to seek to amend its Stock Option and  Incentive  Plan and  Recognition
and Retention Plan to provide for  accelerated  vesting of benefits in the event
of a change of control of Cohoes,  or if  otherwise  determined  by the Board of
Directors.  We are convinced  that a more thorough  review of Cohoes'  strategic
alternatives,  and a greater commitment to pursuing stockholders' interests, can
only be realized by having new directors on the Cohoes Board. Therefore, TrustCo
is  soliciting  your proxy in support of the  election  of M.  Norman  Brickman,
Thomas P. Collins,  Thomas O. Maggs, and Peter A. Pastore to the Cohoes Board of
Directors. Their backgrounds are described below. This proxy statement and White
Proxy Card are being  first  mailed or  furnished  to  stockholders  on or about
October 20, 2000.

      WE URGE YOU NOT TO RETURN THE BLUE PROXY CARD SENT TO YOU BY COHOES.


                                       1

                   THIS SOLICITATION IS BEING MADE BY TRUSTCO
        AND NOT ON BEHALF OF THE COHOES BOARD OF DIRECTORS OR MANAGEMENT

     Your vote is  important,  no matter how many or how few shares you own.  WE
URGE YOU TO MARK,  SIGN,  DATE AND RETURN THE  ENCLOSED  WHITE PROXY CARD IN THE
ENCLOSED  POSTAGE-PAID  ENVELOPE TO VOTE FOR THE ELECTION OF M. NORMAN BRICKMAN,
THOMAS  P.  COLLINS,  THOMAS O.  MAGGS,  AND  PETER A.  PASTORE  TO THE BOARD OF
DIRECTORS  AND  AGAINST  THE  AMENDMENTS  TO THE COHOES  1999  STOCK  OPTION AND
INCENTIVE  PLAN  AND 1999  RECOGNITION  AND  RETENTION  PLAN.  TRUSTCO  MAKES NO
RECOMMENDATION  WITH  RESPECT  TO THE  RATIFICATION  OF ARTHUR  ANDERSEN  LLP AS
COHOES' INDEPENDENT AUDITORS.

     When you return our proxy  card and  follow  our  recommendations,  you are
voting for  Messrs.  Brickman,  Collins,  Maggs,  and  Pastore,  and against the
amendments  to the  Cohoes  1999  Stock  Option  and  Incentive  Plan  and  1999
Recognition  and  Retention  Plan.  There  can be no  assurance  that all of our
nominees  will be elected to the Cohoes  Board of  Directors.  In the event that
less than all of our nominees are elected to the Cohoes Board of Directors there
is no assurance  that any of the other persons  nominated to the Cohoes Board by
either  Cohoes or Ambanc  Holding  Co.,  Inc.,  will serve as  Directors  if our
nominees are elected to the Board.  A plurality of the votes cast will determine
who will be elected to the Cohoes  Board of  Directors.  A majority of the votes
cast are  required  in order to approve  the  proposal  to amend the Cohoes 1999
Stock Option and Incentive Plan and 1999 Recognition and Retention Plan.

    WE BELIEVE THAT THE COHOES BOARD HAS FAILED TO MAXIMIZE STOCKHOLDER VALUE

         o     In October 1998, Cohoes terminated its merger agreement with SFS
               Bancorp, Inc.  The break-up fee that Cohoes had to pay SFS
               Bancorp, Inc. totaled $2.0 million, which increased Cohoes'
               non-interest expense for the fiscal year ended June 30, 1998.(1)
               Cohoes management has failed to advise its stockholders why
               terminating the SFS Bancorp, Inc. merger was more beneficial than
               completing the merger.

         o     In connection with the Cohoes-Hudson River Bancorp merger,
               Cohoes' President and Chief Executive Officer was to receive an
               employment agreement with a SIX-YEAR TERM(2), which we believe
               significantly exceeds industry norms.  We believe that an
               employment agreement with a six-year term does not protect the
               interests of stockholders but serves the interests of the
               President and Chief Executive Officer.

         o     Cohoes' Chief Executive Officer received a 27% increase in his
               salary for fiscal year 1999 as compared to 1998, NOTWITHSTANDING
               A 41% DECREASE IN COHOES' NET INCOME DURING THIS PERIOD.(1)(3)
               The average increase in salaries for chief executive officers of
               banks and thrifts with assets between $500 million and $1.0
               billion was 7.3% in 1999.(4)

         o     Cohoes' return-on-average equity was 4.62% for fiscal year 2000.
               THIS RATIO IS FAR BELOW COHOES' PEER institutions.(5)(6)

         o    For the fiscal year ended June 30, 2000, Cohoes' efficiency ratio
              (normally determined by dividing non-interest expense by net
              interest income plus non-interest income) was 63.18%.  The higher
              the efficiency ratio, the less efficiently the institution is
              operated.  The average efficiency ratio for New York-based thrifts
              was 48.03% as of March 31, 2000. (5)

         o    Cohoes' IPO price was $10 per share. On April 25, 2000, the last
              trading day before public announcement of the Cohoes-Hudson River
              Bancorp merger, the last reported price of the Cohoes common stock
              was $9.813(2) - NEGATIVE RETURN ON YOUR INVESTMENT(7).  We believe
              that the most recent increases in Cohoes' common stock price
              reflect takeover speculation.  WHAT WILL HAPPEN TO COHOES' STOCK
              PRICE IF THERE IS NO TAKEOVER OF COHOES?

         o    Cohoes has made significant restricted stock awards and stock
              option grants to management and the current Board of Directors.
              Cohoes Board of Directors now proposes to amend its 1999 Stock
              Option and Incentive Plan and 1999 Recognition and Retention Plan
              in a manner that would further dilute any merger value to
              stockholders by accelerating the vesting of such stock benefits.
              (8)  THIS PROPOSAL DOES NOT MAXIMIZE STOCKHOLDER VALUE.

                              OBJECTIVES OF TRUSTCO

     TrustCo is a bank holding company  headquartered in Schenectady,  New York,
that operates through its bank subsidiaries Trustco Bank, National  Association,
and Trustco Savings Bank,  which have 54 offices in upstate New York. As of June
30,  2000,   TrustCo  had  total  assets  of  approximately   $2.4  billion  and
stockholders' equity of $176.0 million.  TrustCo's  return-on-average equity was
24.30% (on an  annualized  basis)  and 22.52% for the six months  ended June 30,
2000, and the fiscal year ending December 31, 1999, respectively.

     After  careful  analysis  of  the  operations,  management,  and  financial
performance  of Cohoes,  we have  concluded  that the  strategic  decisions  and
ongoing  actions of the current Cohoes Board and management have not been in the
best interests of stockholders.

     On June 9, 2000,  TrustCo made an offer to acquire  Cohoes.  This offer was
extended in letters  delivered to the Board of Directors of Cohoes.  On June 23,
2000, Cohoes summarily rejected TrustCo's offer. Consequently, on June 26, 2000,
TrustCo  announced  its  intention to initiate a tender offer to acquire  Cohoes
common stock directly from Cohoes  stockholders in an exchange offer. Our tender
offer was originally for $16.00 in TrustCo stock, which  substantially  exceeded
the price offered by the failed Hudson River Bancorp merger.

     On August 17, 2000, Cohoes  stockholders  rejected the proposed merger with
Hudson River Bancorp,  Inc. We believe that the Cohoes Board of Directors should
respect that vote and begin discussions and negotiations with TrustCo,  with the
goal of  combining  our  companies.  We  believe  that  your  vote  against  the
Cohoes-Hudson River Bancorp merger sent a strong message to the Cohoes' Board of
Directors  that you want to preserve  your  opportunity  to accept the  superior
value represented by TrustCo's offer.

Since August 17, 2000, we have  attempted to have  meaningful  discussions  with
Cohoes'  management  and  Chairman  of the Board to discuss the  acquisition  of
Cohoes by TrustCo for a price of $18.00 per share.  TrustCo  delivered to Cohoes
written  proposals  dated August 30, 2000 and  September 7, 2000 that  expressed
TrustCo's  desire to acquire Cohoes at a price of $18.00 per share.  In spite of
our  efforts,  Cohoes'  management  and Board  have been  unwilling  to  discuss
TrustCo's offer with TrustCo's management.  Moreover, more than five weeks after
Cohoes  stockholders  failed to approve the Cohoes-Hudson  River Bancorp merger,
Cohoes  announced  the  termination  of its merger  agreement  with Hudson River
Bancorp.  On  September  28,  2000,  Cohoes  publicly  stated  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  include  the sale of Cohoes  to a larger  financial  institution.  COHOES
ANNOUNCEMENT  FAILED TO  INDICATE  WHETHER  THE COHOES  BOARD OF  DIRECTORS  HAD
CONSIDERED  TRUSTCO'S  $18.00 PER SHARE OFFER OR WHETHER THE BOARD OF  DIRECTORS
HAD DETERMINED TRUSTCO'S OFFER TO BE

                                       3


INADEQUATE.  Consequently,  TrustCo  has  decided to make its offer  directly to
Cohoes'  stockholders for $18.00 per share in a combination of TrustCo stock and
cash. We have filed a  registration  statement  with the Securities and Exchange
Commission relating to our offer. We believe that by electing TrustCo's nominees
to the  Cohoes  Board  you will  send the  message  that you are  interested  in
obtaining more value for your shares, and that you will reject transactions that
perpetuate or reward management at any cost to you as stockholders.

WE BELIEVE THAT OUR NOMINEES WILL PROTECT YOUR  INTERESTS BY INSISTING  THAT THE
COHOES  BOARD  CONSIDER  THE TRUSTCO  OFFER AND OFFERS FROM ANY OTHER  POTENTIAL
ACQUIRORS AND ACT IN THE BEST INTEREST OF ALL STOCKHOLDERS.

         o    BY VOTING FOR TRUSTCO'S NOMINEES, YOU CAN SEND A MESSAGE THAT
              COHOES START ENGAGING IN GOOD FAITH MERGER NEGOTIATIONS WITH
              TRUSTCO AND ANY OTHER INTERESTED ACQUIRORS.

     Since TrustCo's initial  expression of interest in acquiring Cohoes in June
2000, more than four months ago, Cohoes has refused to engage in any substantive
discussions  with TrustCo  regarding  TrustCo's  proposal to acquire Cohoes.  On
September 28, 2000,  Cohoes finally  terminated its merger agreement with Hudson
and announced that it will "immediately begin a comprehensive exploration of all
strategic options," which could, Cohoes admits,  include the sale of Cohoes to a
larger  financial  institution.  The proxy statement for Cohoes' August 17, 2000
meeting of stockholders stated that Cohoes has, on an ongoing basis,  considered
strategic options for increasing  stockholder  value.  TrustCo believes that the
September 28th  announcement  is merely another attempt to delay the inevitable.
It is time  for  Cohoes  to stop  delaying.  Your  vote for  TrustCo's  director
nominees will tell Cohoes clearly and  unequivocally  that it is time for Cohoes
to enter  into good faith  merger  negotiations  with  TrustCo  and anyone  else
interested in acquiring Cohoes.

         o    A VOTE FOR TRUSTCO'S NOMINEES WILL SEND A MESSAGE TO YOUR BOARD
              THAT IT IS TIME FOR THEM TO TAKE CONTROL OF COHOES AND DELIVER
              VALUE TO STOCKHOLDERS.

     TrustCo  believes  that one  reason  for the  failure  of Cohoes to receive
stockholder  approval of its proposed deal with Hudson River was the  perception
that Cohoes'  management was enriching and entrenching  itself at the expense of
Cohoes stockholders. Unfortunately, management's attempts to enrich and entrench
itself appear to TrustCo to be  continuing.  When Cohoes  terminated  its merger
agreement with Hudson River on September 28, 2000, it only amended - but did not
terminate - the stock option  agreements it entered into with Hudson River. As a
result,  the cost to acquire  Cohoes  prior to the  expiration  of the option is
increased  by $3.5  million,  which will go to Hudson  River  rather than Cohoes
stockholders.  We  believe  this  amendment  is  designed  to  further  entrench
management and is diametrically opposed to increasing stockholder value. We also
believe that the  proposal to amend the Cohoes 1999 Stock  Option and  Incentive
Plan and 1999  Recognition  and Retention Plan is another  attempt at enrichment
and entrenchment by, once again,  proposing to increase management  compensation
at the  expense  of  stockholder  value.  TrustCo  believes  that the  continued
existence of the option and the proposed  amendments  to the benefit  plans make
Cohoes more expensive and consequently  less attractive to potential  acquirors.
We believe it is time for Cohoes'  Board of  Directors  to wrest  control of the
Company  away  from  Cohoes'   management,   which  TrustCo  believes  has  lost
credibility  in light of its failed merger  transaction  with Hudson  River.  By
voting for TrustCo's director nominees,  Cohoes  stockholders can send a wake-up
call to the  Cohoes  Board of  Directors  that it is time  for them to  pursue a
merger  transaction that will provide Cohoes  stockholders  with a premium above
the price  levels at which  TrustCo  believes  the Cohoes  common stock could be
expected to trade in the absence of the proposed  TrustCo offer and what TrustCo
believes is the  market's  expectation  that Cohoes will be acquired in the near
future.

     For these reasons, we have decided to initiate a proxy contest to gain four
seats on the Board of Directors. If our nominees, M. Norman Brickman,  Thomas P.
Collins,  Thomas O. Maggs,  and Peter A.  Pastore are elected and take office as
directors, each intends to simultaneously:

         (1)      consider a review of the outstanding proposals to acquire
                  Cohoes; and


                                       4

         (2)      ask the Board of Directors to contact representatives of
                  TrustCo and others regarding the possibility of entering
                  into a negotiated transaction.

     Because  Messrs.  Brickman,  Collins,  Maggs and Pastore would, if elected,
constitute  a  minority  of the Board of  Directors,  any action  authorizing  a
negotiated  transaction with TrustCo or another potential acquiror would require
the approval of other  directors of Cohoes.  There can be no guarantee  that the
other  members of the Cohoes  Board of  Directors  will  agree to  consider  the
TrustCo offer or any other offer presented. However, we believe that such action
will be more likely if there are persons  elected to the Board of Directors  who
are committed to achieving such results.

     OUR NOMINEES ARE  COMMITTED,  SUBJECT TO THEIR  FIDUCIARY  DUTIES TO COHOES
STOCKHOLDERS,  TO GIVING ALL COHOES  STOCKHOLDERS THE OPPORTUNITY TO RECEIVE THE
MAXIMUM  VALUE FOR THEIR SHARES BY ENTERING INTO  NEGOTIATIONS  WITH TRUSTCO AND
ANY OTHER INTERESTED ACQUIROR. A VOTE FOR M. NORMAN BRICKMAN, THOMAS P. COLLINS,
THOMAS O. MAGGS, AND PETER A. PASTORE WILL ENABLE YOU AS THE OWNERS OF COHOES TO
SEND A MESSAGE TO THE BOARD THAT YOU ARE COMMITTED TO ENTERING INTO A NEGOTIATED
TRANSACTION  WITH  TRUSTCO  AND ANY  OTHER  INTERESTED  ACQUIROR  AS A MEANS  OF
MAXIMIZING  THE VALUE OF YOUR SHARES.  A VOTE AGAINST  PROPOSAL NO. 2 WILL ALLOW
YOU TO EXPRESS YOUR  DISPLEASURE OVER THE DESIRE OF THE COHOES BOARD TO INCREASE
THEIR BENEFITS UNDER EXISTING BENEFIT PLANS.

     YOUR VOTE IS  IMPORTANT,  NO MATTER HOW MANY OR HOW FEW SHARES YOU OWN.  WE
URGE YOU TO SIGN,  DATE AND RETURN THE  ENCLOSED  WHITE PROXY CARD TODAY TO VOTE
FOR THE ELECTION OF M. NORMAN BRICKMAN,  THOMAS P. COLLINS, THOMAS O. MAGGS, AND
PETER A.  PASTORE,  AND AGAINST  AMENDMENTS  TO THE COHOES 1999 STOCK OPTION AND
INCENTIVE PLAN AND 1999 RECOGNITION AND RETENTION PLAN.

Further  information  regarding TrustCo is contained at Schedule I to this Proxy
Statement.

                              HOW TO VOTE BY PROXY

     To elect our  nominees to the Board,  and to vote  Against  Proposal No. 2,
promptly  complete,  sign,  date and mail the  enclosed  WHITE proxy card in the
enclosed postage-paid envelope. Whether you plan to attend the Annual Meeting or
not, we urge you to complete and return the enclosed WHITE proxy card. Any proxy
may be revoked at any time  prior to the time a vote is taken by  delivering  to
the  Secretary  of  Cohoes a notice  of  revocation  bearing  a later  date,  by
delivering a duly executed proxy bearing a later date or by attending the Annual
Meeting and voting in person (but  attendance at the Annual  Meeting will not by
itself constitute revocation of a previously delivered proxy).

     Properly  executed  proxies will be voted in accordance with the directions
indicated thereon. If you sign the WHITE proxy card but do not make any specific
choices, your proxy will vote your shares as follows:

PROPOSAL 1.

     - "FOR" the  election of our four  nominees to the Board of  Directors - M.
Norman Brickman, Thomas P. Collins, Thomas O. Maggs, and Peter A. Pastore.

PROPOSAL 2.

     - "AGAINST"  the  amendments  to the Cohoes 1999 Stock Option and Incentive
Plan and 1999  Recognition and Retention Plan to revise the provisions  relating

     If any other matter is presented at the Annual Meeting,  your proxy will be
voted in accordance  with the best judgment of the persons named on the attached
proxy card. At the time of mailing this Proxy  Statement,  we know of no matters
that need to be acted on at the Annual  Meeting  other than those  discussed  in
this Proxy Statement.

     If any of your shares are held in the name of a brokerage firm,  bank, bank

shares and only upon its  receipt of your  specific  instructions.  Accordingly,
please  contact  the person  responsible  for your  account  at such  entity and

You should  also sign,  date and mail the WHITE proxy card your broker or banker
sends you when you receive it.  Please do this for each  account you maintain to
ensure that all of your shares are voted.  Abstentions and broker non-votes will
be counted for purposes of determining that a quorum is present.

       SO RETURN THE WHITE CARD EVEN IF YOU PREVIOUSLY MAILED IN A PROXY.

     This  Proxy  Statement  relates  solely to the  solicitation  of proxies in
connection with the matters to be considered at the Cohoes Annual Meeting and is
neither an offer to sell any shares of TrustCo  common  stock nor a request  for
the  tender  of  Cohoes  common  stock.  The  TrustCo  exchange  offer  is being
registered under the Securities Act of 1933 and is being made only by means of a
Prospectus and related letter of transmittal, which will be mailed separately to
Cohoes stockholders.

     Please  refer  to  Cohoes'  proxy  statement  for  a  full  description  of
management's  proposals,  the  securities  ownership  of Cohoes'  directors  and
executive officers,  information about Cohoes' officers and directors, including
compensation,  information  about the  ratification of the appointment of Arthur
Andersen LLP as  independent  auditors and the date by which  stockholders  must
submit proposals for inclusion in the next Annual Meeting.

                   MATTERS TO BE DECIDED AT THE ANNUAL MEETING

PROPOSAL 1.  ELECTION OF FOUR DIRECTORS TO A THREE-YEAR TERM OF OFFICE

     Cohoes  currently  has  eleven  directors,  and the  terms of four of these
directors will expire at the Annual Meeting.  TrustCo proposes that stockholders
elect M. Norman  Brickman,  Thomas P.  Collins,  Thomas O.  Maggs,  and Peter A.
Pastore to fill the seats open for  election  at the Annual  Meeting.  Set forth
below is information  concerning Mr. Brickman's,  Mr. Collins',  Mr. Maggs', and
Mr. Pastore's  principal  occupation,  experience and certain other matters.  If
elected, Mr. Brickman, Mr. Collins, Mr. Maggs, and Mr. Pastore would hold office
until the 2003 annual meeting of  stockholders  and until their  successors have
been elected and qualified.  Although  TrustCo has no reason to believe that any
of TrustCo's  nominees would be unable to serve as a Cohoes director,  if any of
them is unable to serve or for good cause will not serve,  the persons  named as
proxies on the WHITE proxy card will vote for the election of another nominee or
nominees as may be proposed by TrustCo.

     To date,  the incumbent  Cohoes Board of Directors  has resisted  TrustCo's
attempts to negotiate a merger of Cohoes with TrustCo.  If elected,  each of Mr.
Brickman,  Mr.  Collins,  Mr.  Maggs,  and Mr.  Pastore  will,  subject to their
fiduciary  duties,  seek the prompt review of TrustCo's  offer to acquire Cohoes
and any other potential  transaction that will maximize  stockholder value. Each
of TrustCo's  nominees will evaluate all offers on the basis of the value of the
consideration  offered,  the  ability of the  offeror to  finance  the bid,  the

                                       6

quality and  prospects  of any non-cash  consideration  offered  (including  the
financial condition of any offeror that is offering non-cash consideration), and
the timing and likelihood of receiving necessary regulatory approvals.

     Mr. Brickman,  Mr. Collins,  Mr. Maggs, and Mr. Pastore would comprise only
four  directors on Cohoes'  eleven  member board.  Consequently  there can be no
assurance that Cohoes' Board of Directors  will agree to enter into  discussions
with TrustCo even if all of TrustCo's nominees are elected.

     Each of Mr. Brickman,  Mr. Collins, Mr. Maggs, and Mr. Pastore disclaim any
beneficial interest in any shares of Cohoes common stock owned by TrustCo.

     M. NORMAN  BRICKMAN is 75 years old and his address is 35 Greyledge  Drive,
Albany,  New York.  Mr.  Brickman  was the  President  of D.  Brickman,  Inc., a
wholesale  fruit and produce  business for twenty years,  until 1998.  From 1998
until 1999,  Mr.  Brickman  was Vice  President  of D.  Brickman,  Inc.,  and he
currently serves as its Secretary. Mr. Brickman is a United States citizen.

     THOMAS P. COLLINS, CPA, is 64 years old and his address is 19 Red Oak Lane,
Rensselaer,  New York. For the past 10 years, Mr. Collins has been the President
and owner of The  Preferred  Group,  an Albany based  business  specializing  in
employee  benefits advisory  services.  Mr. Collins also serves as a director of
the following  organizations:  Capital District  Physicians'  Health Plan, Mason
Insurance  Co. and  Universal  Benefits,  Inc.  Mr.  Collins is a United  States
citizen.

     THOMAS  O.  MAGGS is 55 years old and his  address  is 18  Sunnyside  Road,
Scotia,  New York.  For the past 13 years,  Mr. Maggs has been the  President of
Maggs  & Zack,  business  insurance  brokers.  Mr.  Maggs  is a  trustee  of the
Rensselaerville  Institute  and a member  of the  Commission  of New York  State
Historic Sites and Parks. Mr. Maggs is a United States citizen.

     PETER A.  PASTORE is 44 years old and his  address is 75  Fairfield  Drive,
Voorheesville,  New York.  Mr.  Pastore is principal in the law firm of McNamee,
Lochner,  Titus & Williams,  P.C.,  an Albany based law firm.  Mr.  Pastore is a
United States citizen.

     During the last ten years: (i) none of TrustCo, Mr. Brickman,  Mr. Collins,
Mr. Maggs, or Mr. Pastore, to the best of their knowledge, has been convicted in
a criminal  proceeding  (excluding traffic violations or similar  misdemeanors);
and (ii) none of TrustCo, Mr. Brickman,  Mr. Collins, Mr. Maggs, or Mr. Pastore,
to the best of their  knowledge,  has  been a party to a civil  proceeding  of a
judicial or  administrative  body of competent  jurisdiction  and as a result of
such  proceeding  was or is  subject  to a  judgment,  decree,  or  final  order
enjoining future violations of, or prohibiting activities subject to, federal or
state securities laws, or finding any violation with respect to such laws.

     The  voting   power  over  Cohoes'   securities   is  not  subject  to  any
contingencies  beyond  standard  provisions  for entities of this nature  (i.e.,
limited   partnerships  and  limited  liability   companies)  which  govern  the
replacement of a manager or a general partner.

     Schedule II lists certain information regarding TrustCo, Mr. Brickman,  Mr.
Collins,  Mr. Maggs, and Mr. Pastore,  including their holdings of Cohoes common
stock and transactions in the common stock during the last two years.

     Except as set forth herein, neither TrustCo, Mr. Brickman, Mr. Collins, Mr.
Maggs,  nor Mr. Pastore is now, or within the past year has been, a party to any
contract,  arrangement  or  understanding  with any person  with  respect to any
securities of Cohoes  (including,  but not limited to, joint  ventures,  loan or
option  arrangements,  puts or calls,  guarantees  against loss or guarantees of
profit, division of losses or profits, or the giving or withholding of proxies).

     There are no material proceedings to which TrustCo or any of its associates
is a party  adverse  to  Cohoes  or any of its  subsidiaries  or has a  material
interest adverse to Cohoes or any of its subsidiaries. Except as

                                       7

described herein,  neither TrustCo,  Mr. Brickman,  Mr. Collins,  Mr. Maggs, Mr.
Pastore, nor any associate of such persons has any interest in the matters to be
voted  upon at the  Annual  Meeting,  other  than  an  interest,  if  any,  as a
stockholder of Cohoes.  Each of Mr.  Brickman,  Mr. Collins,  Mr. Maggs, and Mr.
Pastore has consented to being nominated to serve as a director of Cohoes, named
as a nominee in TrustCo's proxy statement and to serve, if elected.
     Except  as  described  herein  or in  Schedule  II,  neither  TrustCo,  Mr.
Brickman, Mr. Collins, Mr. Maggs, Mr. Pastore nor any associate of such persons:
(1) has engaged in or has a direct or indirect  interest in any  transaction  or
series of  transactions  since the  beginning of Cohoes' last fiscal year, or in
any currently proposed  transaction,  to which Cohoes or any of its subsidiaries
is a party  where the amount  involved  was in excess of  $60,000;  (2) has been
indebted to Cohoes or any of its  subsidiaries;  (3) has  borrowed any funds for
the purpose of acquiring or holding any  securities of Cohoes,  or is presently,
or has been  within  the past  year,  a party to any  contract,  arrangement  or
understanding  with any person with  respect to any  securities  of Cohoes,  any
future  employment by Cohoes or its  affiliates,  or any future  transaction  to
which  Cohoes  or any of its  affiliates  will or may be a party;  or (4) is the
beneficial  or  record  owner of any  securities  of  Cohoes  or any  parent  or
subsidiary thereof.

PROPOSAL 2.  AMENDMENTS TO THE COHOES 1999 STOCK OPTION AND  INCENTIVE  PLAN AND
1999  RECOGNITION  AND RETENTION PLAN TO REVISE THE  PROVISIONS  RELATING TO THE
VESTING OF OPTIONS AND RESTRICTED STOCK AWARDS.

     Cohoes'  Board of Directors is proposing to amend its 1999 Stock Option and
Incentive Plan and its 1999 Recognition and Retention Plan. The purpose of these
amendments would be to: (1) permit Cohoes to remove various  restrictions on the
acceleration of option grants and restricted stock awards;  (2) provide that new
awards  would vest at a rate  determined  by the Cohoes  Board of Directors or a
committee  administering  the plans; and (3) provide for accelerated  vesting of
option grants and restricted  stock awards upon a change of control of Cohoes or
the retirement of the employee.

     Based upon information  contained in Cohoes' proxy statement for its Annual
Meeting of  Stockholders,  each of the 10  non-employee  directors of Cohoes has
8,322 unvested shares of restricted stock and unvested options to acquire 20,804
shares  of  common  stock.  Harry L.  Robinson  has  90,000  unvested  shares of
restricted stock and unvested options to acquire 225,000 shares of common stock.
Richard A. Ahl has  45,000  unvested  shares of  restricted  stock and  unvested
options to acquire  112,500 shares of common stock.  Albert J. Picchi has 22,500
unvested  shares of  restricted  stock and  unvested  options to acquire  56,250
shares of common stock. Other officers and employees have 58,440 unvested shares
of restricted  stock and unvested  options to acquire  144,596  shares of common
stock.

We  believe  that  the  proposed  amendments  are not in the best  interests  of
stockholders for the following reasons:

         o    The Cohoes Board of Directors has stated that it is exploring all
              strategic options, including the sale of Cohoes.  The amendments
              to the stock benefit plans would result in the dilution of your
              stock ownership interest in Cohoes without any benefit in return.
              We believe that the amendments would result in your receiving less
              per share in the event of a sale of Cohoes because the total
              Cohoes shares to be acquired in a sale would increase by the
              299,160 restricted shares and the 746,386 shares that would be
              acquired upon the exercise of options.(1)  If the amendments were
              adopted, all of the options and restricted shares would be
              accelerated upon a change of control without any commensurate
              increase in the value of Cohoes.(2)  Although the Cohoes' Board of
              Directors says it is interested in maximizing value for current
              Cohoes stockholders, we believe the proposed amendments would
              produce the opposite result.
______________________
(1)  Value of each option would be determined as the difference between the
     sales price of the Cohoes' common stock less the option exercise price.
(2)  Under certain circumstances, the economic benefit of the restricted stock
     awards and stock option plans may be paid out to Messrs. Robinson, Ahl and
     Picchi pursuant to their employment agreements.

                                       8


         o    If Cohoes does not enter into an agreement to be sold and the
              restrictions on the restricted stock awards and stock option
              grants are modified or removed, Cohoes may have to recognize
              additional compensation expense which will adversely affect its
              net income.

     The Cohoes Board has  indicated  that the 1999 Stock  Option and  Incentive
Plan and the 1999  Recognition  and  Retention  Plan were adopted to attract and
retain qualified personnel in key positions, retain directors,  provide officers
and employees with a proprietary  interest in Cohoes as a performance  incentive
and reward key employees for outstanding performance. We believe the best way to
ensure the goals stated by the Cohoes Board is to have the Cohoes  directors and
employees  EARN their awards over 5 years,  which was the original  intention of
the Board of Directors at the time the options were granted and restricted stock
was awarded. THIS IS THE BASIS UPON WHICH STOCKHOLDERS APPROVED THESE PLANS ONLY
ONE YEAR AGO. TrustCo believes that Cohoes'  management has not provided Cohoes'
stockholders with the financial  results that justify these increased  benefits.
As noted above, Cohoes  return-on-average  equity during its 2000 fiscal year is
far below its peer group.

     THE COHOES BOARD OF DIRECTORS HAS NOT DEMONSTRATED THAT THE ADOPTION OF THE
PROPOSED  AMENDMENTS WILL IN ANY WAY ENHANCE  STOCKHOLDER VALUE. We believe that
adoption of the amendments will  effectively  reduce the amount per share that a
stockholder of Cohoes will receive in the event of a sale of Cohoes, and if such
a sale does not occur,  the  amendment  may  negatively  impact the  earnings of
Cohoes.  FOR THESE REASONS,  TRUSTCO RECOMMENDS THAT STOCKHOLDERS VOTE "AGAINST"
APPROVAL OF THE  AMENDMENTS TO THE COHOES 1999 STOCK OPTION AND  INCENTIVE  PLAN
AND 1999 RECOGNITION AND RETENTION PLAN.

     The  amendments to the Cohoes 1999 Stock Option and Incentive Plan and 1999
Recognition and Retention Plan are set forth at Appendix A and Appendix B to the
Cohoes proxy statement,  are incorporated by reference into this proxy statement
and should be reviewed in their entirety.

PROPOSAL 3.  RATIFICATION OF ARTHUR ANDERSEN LLP AS COHOES'  INDEPENDENT  PUBLIC
ACCOUNTANTS

     In the past,  Cohoes has asked  stockholders to ratify the  solicitation of
Arthur Andersen LLP as Cohoes' independent public accountants.  We are providing
the means for stockholders to vote on the ratification of Arthur Andersen LLP as
Cohoes'  independent  public  accountants  for the year  ending  June 30,  2001.
TrustCo,   however,  does  not  make  a  recommendation  with  respect  to  such
ratification.

OTHER MATTERS

     The Cohoes proxy statement contains information  regarding:  (1) securities
ownership of 5% or more beneficial ownership and management;  (2) the committees
of Cohoes'  Board of  Directors;  (3) the meetings of the Board of Directors and
all committees  thereof;  (4) the  background of the management  nominees to the
Board of Directors;  (5) the compensation  and remuneration  paid and payable to
Cohoes'  directors  and  management;  (6) stock price  performance;  and (7) the
submission  of  stockholder  proposals  at the Annual  Meeting of  stockholders.
TrustCo has no  knowledge of the  accuracy of Cohoes'  disclosures  in its proxy
materials.

SOLICITATION OF PROXIES

     Proxies will be  solicited by mail,  telephone,  telecopy,  telegraph,  the
Internet,  newspapers  and other  publications  of general  distribution  and in
person.  Directors,  officers  and  certain  employees  of TrustCo and the other
participants  listed on  Schedule  II hereto may assist in the  solicitation  of
proxies  without any additional  remuneration  (except as otherwise set forth in
this proxy statement).  The expenses to conduct the solicitation are expected to
be  $67,000,  of  which  $21,000  has been  spent as of the date of this  proxy.
TrustCo will bear the costs of the solicitation and will not seek  reimbursement
of expenses from Cohoes.

     TrustCo   has   retained   Georgeson   Shareholder   Communications,   Inc.
("Georgeson")   for  solicitation  and  advisory  services  in  connection  with
solicitations  relating to the Annual Meeting, for which Georgeson is to receive
a  fee  of  $25,000.   TrustCo  has  also  agreed  to  reimburse  Georgeson  for
out-of-pocket  expenses and to indemnify  Georgeson against certain  liabilities
and expenses,  including reasonable legal fees and related charges in connection
with its solicitation activities.  Georgeson will solicit proxies for the Annual
Meeting from


                                       9

individuals,  brokers,  banks, bank nominees and other institutional holders. In
addition,  TrustCo  has  retained  Georgeson  to act  as  information  agent  in
connection with the TrustCo offer.  TrustCo has agreed that it will pay a fee of
$10,000 to Georgeson for services as information agent,  reimburse Georgeson for
out-of-pocket  expenses and to indemnify  Georgeson against certain  liabilities
and expenses,  including reasonable legal fees and related charges in connection
with its engagement as information agent.

     Directors,  officers  and  certain  employees  of TrustCo may assist in the
solicitation of proxies without any additional remuneration.  The entire expense
of soliciting proxies for the Annual Meeting by or on behalf of TrustCo is being
borne by TrustCo.
