                                              December 14, 2005


To Our Fellow Shareholders:

You have been presented with an excellent offer by TrustCo to purchase your
stock at $45.50 a share. Unfortunately, the management of Ballston Spa Bancorp,
Inc. has issued self-serving advice intended to further entrench themselves and
mislead you into declining such a great deal. We therefore urge you to consider
the following:

o    Consolidation of weakly performing banks is inevitable, and nothing in
     Ballston Spa's performance history suggests an ability to remain
     independent over the long term. TrustCo's offer will keep the bank locally
     based while maximizing your investment.

o    The December 7th response of Ballston Spa's board was not well deliberated
     as indicated by the inconsistencies contained therein. It was issued only
     48 hours after stating outside counsel was going to be hired to help them
     evaluate our December 5th offer.

o    TrustCo's $45.50 offer is an excellent offer by any measure.  It is
     44% above where the stock was trading at $31.50 on August 24th when we
     first contacted Ballston Spa.

o    Despite misleading statements by management, TrustCo's offer has every
     chance of succeeding and we are very serious about obtaining control of 
     the company. Management's extreme response to our proposal should 
     demonstrate this to you and enable you to see through their smokescreen.

o    TrustCo is one of the best performing banks in the country. We offer
     friendly branch service and superb deposit and loan products. Our success
     and enthusiastic support from both customers and investors alike have
     enabled TrustCo to grow and achieve results far beyond those of Ballston
     Spa.



                                       5



o    As customers of TrustCo, existing Ballston Spa customers would continue to
     have the service of a locally based bank plus access to over 60 Capital
     District branch offices. Offices we are opening in Florida, downstate New
     York, and New Jersey would also be at their disposal.

o    TrustCo proudly represents over 100 years of strong community support in
     the Capital District. We have 14 branches in Saratoga County, versus nine
     for Ballston Spa, and have donated hundreds of thousands of dollars to
     local charities and thousands of hours of community service by TrustCo
     employees.

o    As indicated by Bloomberg Financial Services, over the last five years
     Ballston Spa investors have suffered an annual compound loss of 2% on 
     their investment. TrustCo investors, meanwhile, have enjoyed a compounded
     annual gain of 11% over the same period.

o    The 70% earnings per share gains for Ballston Spa referenced by Mr. Dowd
     are quite misleading because they followed very depressed results for the
     company. So Ballston Spa management is saying to you they are proud of the
     fact they did much better than their prior poor performance. Not much
     comfort, especially since even based on the "improved" results the
     company's operating results remain anemic and well below industry 
     averages.

o    Neither Mr. Dowd, CEO nor Mr. Blow, CFO, currently lives in Saratoga 
     County.

o    Mr. Dowd, CEO did not personally own a single share of Ballston Spa 
     Bancorp stock until September 2005, which was subsequent to the initial
     discussions with TrustCo. This lack of investment in the company he leads
     should demonstrate to you his true commitment to the future of Ballston 
     Spa Bancorp. Mr. Blow, CFO continues to not own any shares of the company.
     Today's community banks distinguish themselves when their leadership takes
     on the same investment risk as their stockholders. This is not the case at
     Ballston Spa.

o    The current Federal capital gains tax rate of 15% is lower than it has
     been in many years. This rate is currently scheduled to return to the
     personal income tax rate in the future unless extended by the U.S.
     Congress.



                                       6




Do not let the personal agenda of a few individuals cause you to miss out on
this great opportunity! We are encouraged by the positive response we have
received to date from many Ballston Spa shareholders and urge you to also
respond.

By accepting this offer you can achieve a superb investment return immediately
far beyond what current management has shown an ability to achieve.
Additionally, you will also put the company into the hands of a strong local
bank with the performance ability and financial strength to remain independent.

We hope this letter has helped you better understand the issues at hand and
clarified some of the misleading statements by Ballston Spa management. We
appreciate your support.

Very truly yours,



Robert J. McCormick
President & Chief Executive Officer
TrustCo Bank Corp NY
