                  NBT BANCORP ANNOUNCES SECOND QUARTER EARNINGS
                           AND DECLARES CASH DIVIDEND

     NORWICH, NY (July 23, 2001) - NBT Bancorp Inc. (NBT) (NASDAQ: NBTB) today
reported net income of $4.7 million, or $.19 diluted earnings per share, for the
quarter ended June 30, 2001 compared to $4.1 million, or $.17 diluted earnings
per share, for the same period a year ago. Second quarter 2001 results included
a loan loss provision of $6.5 million compared to a loan loss provision of $2.3
million for the second quarter of 2000. Results for the quarter ended June 30,
2000 included $2.8 million of pre-tax merger and acquisition costs.

     Net income for the six months ended June 30, 2001 was $12.3 million, or
$.51 diluted earnings per share, compared to $9.3 million, or $.40 diluted
earnings per share, for the first six months of 2000. The loan loss provision
for the first six months of 2001 amounted to $7.5 million compared to $3.8
million for the same period in 2000. Results for the six months ended June 30,
2000 include $4.0 million in pre-tax merger and acquisition costs.

     In commenting on the results, NBT President and CEO Daryl R. Forsythe
stated, "In conjunction with the final stages of the integration of our new
Pennsylvania banking division and consistent with our conservative approach to
identifying and resolving troubled loans, we recorded net chargeoffs of $5.5
million, or 0.3% of average loans, this quarter. In addition, we have increased
the allowance for loan losses through a $6.5 million second quarter loan loss
provision. The credit administration function for the Pennstar Bank division of
NBT Bank, N.A., including workout and collections, has now been consolidated and
standardized using the NBT Bank model, and a new senior vice president of
commercial lending has been installed at the Pennstar Bank division to oversee
our business lending operations in Pennsylvania. We believe that our integration
process has been thorough and are pleased that delinquency trends have begun to
improve through the consolidation of our collection efforts."

                                      -1-


     Nonperforming loans at June 30, 2001 were $24.8 million compared to $22.5
million at March 31, 2001 and $12.5 million at June 30, 2000. The ratio of the
allowance for loan losses to total loans was 1.41% at June 30, 2001, 1.40% at
March 31, 2001 and 1.36% at June 30, 2000. The allowance for loan losses as a
percent of nonperforming loans was 103.57% at June 30, 2001 compared to 107.57%
at March 31, 2001 and 175.91% at June 30, 2000.

     "We remain focused on the effective integration of our acquisitions to
allow for the delivery of high quality financial services in an efficient and
streamlined manner," said Forsythe. "In doing so, we will not compromise our
commitment to strong asset quality and excellent customer service. We are
pleased with the growth and diversification we have been able to achieve in
recent years and are confident that we have laid a solid foundation on which to
leverage our performance."

     Net interest income was $25.5 million for the second quarter of 2001,
compared to $23.5 million for the second quarter of 2000. The increase in net
interest income was primarily attributable to the decline in the Company's cost
of funds year over year combined with growth in the loan portfolio. Net interest
income for the six months ended June 30 increased 6.6% from $46.8 million in
2000 to $49.9 million in 2001. The Company's net interest margin improved to
4.32% for the second quarter of 2001 compared to 4.16% for the same period a
year ago.

     Noninterest income increased 27.6% from $5.0 million for the second quarter
of 2000 to $6.3 million for the second quarter of 2001. Income from service
charges on deposit accounts increased 32.6%, or $659,000, due to increases in
both the number of deposit accounts and the related fees. Broker/dealer fees
increased 58.7%, or $333,000, due to a full three months of revenue in the
second quarter of 2001 from the Company's broker/dealer, M. Griffith, Inc.,
which was acquired on May 5, 2000. For the six months ended June 30, 2001,
noninterest income, excluding net securities gains and the gain on the sale of a
branch building, totaled $12.5 million compared to $9.2 million for the same
period in 2000, an increase of 36.2%. The increase was attributable primarily to
increased deposit service charges and broker/dealer fees.

     Noninterest expense, excluding nonrecurring items such as merger and
acquisition costs and certain deposit overdraft write-offs, increased
approximately 11% for both the three-month and six-month periods ended June 30,
2001 compared to the same periods a year ago. The Company's growth through
acquisition contributed to increased expenses for salaries and benefits,
supplies and postage, and data processing and communications. The Company's
efficiency ratio remained relatively constant at 57.75% for the six months ended
June 30, 2001 compared to 57.31% for the same period in 2000.

     Total assets were $2.7 billion at June 30, 2001 compared to $2.5 billion at
June 30, 2000. Loans increased 12.0% from $1.6 billion at June 30, 2000 to $1.8
billion at June 30, 2001. Total deposits increased 9.6% from $1.9 billion at
June 30, 2000 to $2.1 billion at June 30, 2001. Total borrowings declined $38.4
million from June 30, 2000 to June 30, 2001. Shareholders' equity was $229.3
million, representing a Tier 1 leverage ratio of 7.59%, at June 30, 2001,
compared to $200.6 million, or 8.26%, at June 30, 2000. The Company's tangible
book value per share increased from $7.79 at June 30, 2000 to $7.89 at June 30,
2001.

*historical NBT Bancorp Inc. only

**This price was reported on June 29, 2001, a day on which the Nasdaq Stock
Market experienced computerized trading disruptions which, among other things,
forced it to extend its regular trading session and cancel its late trading
session. Subsequently the Nasdaq Stock Market recalculated and republished
several closing stock prices (not including NBT Bancorp Inc., for which it had
reported a closing price of $19.30). Excluding trading on June 29, 2001, the
high sales price for the quarter ended June 30, 2001 was $16.75.


All common stock and per share data has been restated to give retroactive effect
to stock dividends and splits.
