FOR IMMEDIATE RELEASE:


                 TrustCo Announces Record Third Quarter Results

Glenville, New York - October 18, 2005 TrustCo Bank Corp NY (TrustCo, Nasdaq:
TRST) today announced record third quarter results for 2005. Net income for the
third quarter was $15.7 million, compared to $15.2 million for the third
quarter of 2004, an increase of 3.3%. Diluted earnings per share were $0.208
for the third quarter of 2005 compared to $0.203 for the third quarter of 2004.

Year to date results reflect increases in both net income and diluted earnings
per share between 2004 and 2005. For the nine months ended September 30, 2005
net income was $45.6 million and diluted earnings per share were $0.605
compared to net income of $43.7 million and diluted earnings per share of
$0.582 for the comparable nine-month period in 2004. The nine-month results
reflect an increase of 4.3% in net income and 4.0% in diluted earnings per
share for 2005 compared to the same nine-month period in 2004.

Commenting on the results, Robert J. McCormick, President and Chief Executive
Officer noted, "The current quarter and the year to date 2005 results are
strong and set the stage for continued growth for the remainder of the year."

continuing to open an additional six offices in late 2005 or early 2006. Five
of these branches are in the Orlando Florida region. Robert J. McCormick

provide us with continued increases in revenue into the future."
