                                    AND TRUST


This is a summary of the annual report for THE BANK OF GREENE COUNTY  EMPLOYEES'
SAVINGS & PROFIT SHARING PLAN AND TRUST,  EIN 14-0553610,  Plan No. 002, for the

filed with the Employee Benefits  Security  Administration,  U.S.  Department of
Labor,  as required under the Employee  Retirement  Income  Security Act of 1974
(ERISA).

                            Basic Financial Statement

Benefits  under the plan are provided  through a trust fund.  Plan expenses were
$78,203.  These expenses  included  $61,685 in benefits paid to participants and
beneficiaries  and  $16,518  in  other  expenses.  A total of 113  persons  were
participants  in or  beneficiaries  of the  plan  at the end of the  plan  year,
although not all of these persons had yet earned the right to receive benefits.

The  value of plan  assets,  after  subtracting  liabilities  of the  plan,  was
$2,993,778  as of December 31,  2005,  compared to  $2,595,534  as of January 1,
2005. During the plan year the plan experienced an increase in its net assets of

value of plan assets;  that is, the  difference  between the value of the plan's
assets at the end of the year and the value of the  assets at the  beginning  of
the year or the cost of assets  acquired  during  the  year.  The plan had total
