Dear Stockholder:

We are pleased to enclose a check or Dividend  Reinvestment  Statement  for your
First  Quarter 2001 cash  dividend  payable at the rate of $0.17 per share.  The
dividend is being paid on March 15, 2001 to  stockholders  of record as of March
1, 2001. This is the 436th  consecutive cash dividend paid by NBT Bancorp or NBT
Bank over the past 145 years.

The year 2000 was a challenging and productive one for our  organization.  While
maintaining  our focus on core  earnings,  we  closed  mergers  with Lake  Ariel
Bancorp,  Inc.  and Pioneer  American  Holding  Company  Corp.  and  acquired M.
Griffith,  Inc., an investment and financial  advisory  firm.  During the fourth
quarter of 2000 we  integrated LA Bank,  Pioneer  American Bank and six branches
acquired from Sovereign Bank to form Pennstar Bank.  Total assets of NBT Bancorp
at year-end exceeded $2.6 billion,  and our banking  subsidiaries,  NBT Bank and
Pennstar Bank, now boast a total of 77 branches and over 120 ATMs.

Our core earnings for 2000, which exclude merger, acquisition and reorganization
costs  and other  nonrecurring  items,  remained  strong  at $25.8  million,  up
marginally  from the previous  year's core earnings of $25.6  million.  One-time
after-tax costs associated with merger and acquisition activity, reorganizations
and other nonrecurring items did impact our 2000 earnings significantly with net
income of $7.2 million  reported for the twelve months ended  December 31, 2000.
Despite the cost, our efforts in 2000 were  successful  and have  positioned NBT
Bancorp to build stockholder value in 2001 and beyond.  Our expanded market area
and  product  line have and will  continue to enhance our ability to develop and
maintain long-term customer  relationships through our community-based  approach
to the delivery of banking and financial services.

We will soon have the opportunity to discuss developments at NBT Bancorp and our
plans for the future at the Annual Meeting of Stockholders  on Thursday,  May 3,
2001.  The meeting will take place at 10:00 AM at the  Binghamton  Regency,  One
Sarbro  Square,  Binghamton,  New York.  We look  forward to seeing  many of you
there. Thank you for your support as we have worked to grow the Company and your
investment.

Sincerely,


/S/  Daryl R. Forsythe

Daryl R. Forsythe
President and
Chief Executive Officer

This letter to our  stockholders  may be deemed to be  solicitation  material in
respect of the NBT Bancorp Annual Meeting of  Stockholders  scheduled for May 3,
2001.  Filing of this letter to  stockholders  is being made in connection  with

the  aggregate  1,810,053  shares,  or  approximately  7.60%,  of NBT  Bancorp's
outstanding  common  stock.  Additional  information  about  our  directors  and
executive  officers is included in our preliminary  proxy statement for our 2001
Annual Meeting of Stockholders filed with the SEC on March 7, 2001.

preliminary proxy statement, and to read the definitive proxy statement after it
is filed, because these documents contain important information about our annual
meeting.  The  preliminary  proxy  statement  is  available  for  free,  and the

free,  both on the SEC's web site  (www.sec.gov)  and by  contacting  Michael J.
