To Our Fellow Shareholders:

We would like to first thank the many shareholders of Ballston Spa who have
chosen to tender their shares to TrustCo.

The majority of the shareholders that have contacted us have commented that our
cash offer of $45.50 was tremendous. Unfortunately, they were unaware, since 
the stock is so closely traded, how poorly their investment in Ballston Spa 
National Bank has performed over the years.

If you have still not tendered your shares, please remember our cash offer of
$45.50 per share is:

o 49 times higher than Ballston Spa's $0.92, 2004 earnings per share. o 44%
above their August 24th stock price (when we first contacted Ballston Spa). o
Ballston Spa's efficiency ratio of 88% is 60% higher than the industry average
(lower is better). o Your investment in Ballston Spa has lost 2% per year over
the last five years.

We encourage you to not be swayed by the empty promises of the management of
Ballston Spa. Do what is best for you, your family and the community.

Thank you again and should you have any additional questions, please call our
information agent Regan and Associates, Inc. toll free at 800-737-3426.

Very truly yours,

/s/ Robert J. McCormick
