COHOES BANCORP TO EXPLORE STRATEGIC OPTIONS

COHOES, NEW YORK, September 28, 2000 - Cohoes Bancorp, Inc. (Nasdaq NMS: COHB)
announced today that its Board of Directors and management, together with the
Company's financial and legal advisors, will immediately begin a comprehensive
exploration of all strategic options, which could include the sale of the
Company to a larger financial institution.  The Company has engaged Keefe,
Bruyette & Woods, Inc. to assist in the evaluation of the Company's strategic
options.

Harry L. Robinson, President of Cohoes, said "Cohoes Bancorp has a record of
solid financial performance and a strong balance sheet.  With today's action,
the Board of Directors reaffirms its commitment to act in the best interests
of all stockholders, as it seeks to maximize the value of our franchise."

As part of its determination to explore strategic options, Cohoes' Board of
Directors once again considered the unsolicited tender offer from Ambanc
Holding Co. and the price publicly announced by TrustCo Bank Corp. in its
proposed unsolicited tender offer.  The Board continues to believe that these
prices are inadequate and not in the best interests of Cohoes stockholders.
"We are confident there are more valuable alternatives to Ambanc and TrustCo,
and we strongly recommend that Cohoes stockholders should not tender their
shares to either Ambanc or TrustCo," Mr. Robinson said.

"In light of the Board's decision to explore all strategic options, including
a sale of the Company, we urge Ambanc and TrustCo to abandon their tender
offers and to forego their intended fight for Board seats.  We believe that
continuation of these efforts by Ambanc and TrustCo will be disruptive,
expensive and could delay or impede our efforts to maximize value for all of
our stockholders.  The same is true with respect to the meritless lawsuit that
was previously filed," stated Mr. Robinson.

Cohoes and Hudson River Bancorp jointly announced earlier today the
termination of their April 25, 2000 merger agreement.  Cohoes and Hudson River
also agreed to cap the economic value of their reciprocal stock option
agreements in each other at $3.5 million.  As a result of the termination of
the merger agreement, Cohoes recognized $313,000 of pre-tax merger related
expenses in the June 30, 2000 quarter.  Cohoes' net income for the year ended
June 30, 2000 was restated from $6,077,000 to $5,879,000 and from $.76 to $.74
earnings per share.  Mr. Robinson said, "We have the greatest respect for
Hudson River as a company and for its directors and officers.  While we regret
that our merger of equals was not approved, we know that Hudson River will
continue to be a company dedicated to meeting the borrowing and savings needs
of its customers and the communities it serves."
