     WHEREAS, Executive is the president and chief operating officer and a
director of NBT Bank, National Association, a national banking association which

     WHEREAS, NBTB desires to secure the continued employment of Executive,
subject to the provisions of this Agreement; and

     WHEREAS, Executive is desirous of entering into the Agreement for such
periods and upon the terms and conditions set forth herein;

     NOW, THEREFORE, in consideration of the premises and mutual covenants and
agreements hereinafter set forth, intending to be legally bound, the parties

organizations, (ii) manage his personal investments, and (iii) with the prior
permission of the chief executive officer of NBTB, hold such other directorships

                    (vii)  Executive's  resignation  for  "Good  Reason."

event:

                    (i)  any salary (as hereinafter defined) payable pursuant to
section 3(a)(i) hereof which shall have accrued as of the Termination Date; and

shall be entitled to receive:

                    (i)  any  salary  payable pursuant to section 3(a)(i) hereof
which shall have accrued as of the Termination Date, and, for the period
commencing on the date immediately following the Termination Date and ending
upon and including the latest of January 1, 2005, the date to which the Term of
Employment shall (as of the Termination Date) have automatically extended itself

                                      II-42

under section 2(a)(i) hereof, or the second anniversary of the Termination Date,
salary payable at the rate established pursuant to section 3(a)(i) hereof, in a
manner consistent with the normal payroll practices of NBTB with respect to

notwithstanding, in the event that the employment of Executive with NBTB is
terminated in any situation described in section 3 of the change-in-control
letter agreement dated July 23, 2001 between NBTB and Executive (the
"Change-in-Control Agreement") so as to entitle Executive to a severance payment
and other benefits described in section 3 of the Change-in-Control Agreement,
then Executive shall be entitled to receive the following, and no more, under
this section 2:

                    (i)  any  salary  payable pursuant to section 3(a)(i) hereof
which shall have accrued as of the Termination Date;

and

                    (iii)  the  severance payment and other benefits provided in

     3.     Compensation.  For the services to be performed by Executive for
            ------------

                    (i)  NBTB  shall  pay Executive a salary which, on an annual

time.

                    (ii) Executive  shall be entitled to annual salary increases
of 8 percent during the Term of Employment, beginning in 2003, and shall be
eligible to be considered for further salary increases, upon review, in
accordance with the compensation policies of NBTB with respect to executive
personnel as presently in effect or as they may be modified by NBTB from time to
time.

                    (iii)  Executive  shall  be  eligible  to  be considered for
performance bonuses commensurate with the Executive's title and salary grade, in
accordance with the compensation policies of NBTB with respect to executive
personnel as presently in effect or as they may be modified by NBTB from time to
time.

          (b)  Employee  Benefit  Plans  or  Arrangements.  During  the  Term of
               ------------------------------------------
Employment, Executive shall be entitled to participate in all employee benefit
plans of NBTB, as presently in effect or as they may be modified by NBTB from
time to time, under such terms as may be applicable to officers of Executive's
rank employed by NBTB or its affiliates, including, without limitation, plans
providing retirement benefits, stock options, medical insurance, life insurance,
disability insurance, and accidental death or dismemberment insurance, provided
that there be no duplication of such benefits as are provided under any other
provision of this Agreement.

          (c)  Stock  Options.  Each  January  or  February  annually during the
               --------------
Term of Employment, NBTB will cause Executive to be granted a non-statutory
("non-qualified") stock option (each an "Option") to purchase the number of
shares of the common stock of NBTB, $0.01 par value (the "NBTB Common Stock"),
pursuant to the NBT Bancorp Inc. 1993 Stock Option Plan, as amended, or any
appropriate successor plan (the "Stock Option Plan"), computed using a formula
approved by NBTB that is commensurate with the Executive's title and salary
grade.   The option exercise price per share of the shares subject to each
Option shall be such Fair Market Value, and the terms, conditions of exercise,
and vesting schedule of such Option shall be as set forth in section 8 of the
Stock Option Plan.


                                      II-43

          (d)  Vacation  and  Sick  Leave.  During  the  Term  of  Employment,
               --------------------------
Executive shall be entitled to paid annual vacation periods and sick leave in
accordance with the policies of NBTB as in effect as of the Commencement Date or
as may be modified by NBTB from time to time as may be applicable to officers of
Executive's rank employed by NBTB or its affiliates, but in no event less than
four weeks of paid vacation per year.

          (e)  Automobile.  During  the  Term  of Employment, Executive shall be
               ----------
entitled to the use of an automobile owned by NBTB or an affiliate of NBTB, the
make, model, and year of which automobile shall be appropriate to an officer of
Executive's rank employed by NBTB or its affiliates and consistent with that
provided to others of Executive's rank employed by NBTB or its affiliates.
During the second year of the Term of Employment, the automobile used by
Executive will be replaced with a new automobile, whose value shall not exceed
$45,000 escalated by an amount calculated by the controller's division of NBT
Bank to adjust for the effect of inflation upon $45,000 between the Commencement
Date and the date of the replacement of the vehicle (an "Inflation Adjustment").
During the remaining term of the Term of Employment, should three years elapse
from the date of the automobile replacement described in the previous sentence
(or any subsequent automobile replacement that takes place under this section),
or, if earlier, should the replaced automobile (or any automobile provided under
such subsequent automobile replacement) have accumulated 50,000 miles, then it
will be replaced with a new automobile whose value shall not exceed the sum of
$45,000 and an Inflation Adjustment.  Executive shall be responsible for all
expenses of ownership and use of any such automobile, subject to reimbursement
of expenses for business use in accordance with section 3(h).

          (f)  Country  Club  Dues.  During  the  Term  of Employment, Executive
               -------------------

          (g)  Withholding.  All  compensation  to  be  paid  to  Executive
               -----------
hereunder shall be subject to required withholding and other taxes.

               --------
reimbursed for reasonable travel and other expenses incurred or paid by
Executive in connection with the performance of his services under this
Agreement, upon presentation of expense statements or vouchers or such other
supporting information as may from time to time be requested, in accordance with
such policies of NBTB as are in effect as of the Commencement Date and as may be
modified by NBTB from time to time, under such terms as may be applicable to
officers of Executive's rank employed by NBTB or its affiliates.
     4.     Confidential Business Information; Non-Competition.
            --------------------------------------------------

          (a)  Executive  acknowledges  that  certain business methods, creative
techniques, and technical data of NBTB and its affiliates and the like are
deemed by NBTB to be and are in fact confidential business information of NBTB
or its affiliates or are entrusted to third parties.  Such confidential
information includes but is not limited to procedures, methods, sales
relationships developed while in the service of NBTB or its affiliates,
knowledge of customers and their requirements, marketing plans, marketing
information, studies, forecasts, and surveys, competitive analyses, mailing and
marketing lists, new business proposals, lists of vendors, consultants, and
other persons who render service or provide material to NBTB or NBT Bank or
their affiliates, and compositions, ideas, plans, and methods belonging to or
related to the affairs of NBTB or NBT Bank or their affiliates.  In this regard,
NBTB asserts proprietary rights in all of its business information and that of
its affiliates except for such information as is clearly in the public domain.
Notwithstanding the foregoing, information that would be generally known or
available to persons skilled in Executive's fields shall be considered to be
"clearly in the public domain" for the purposes of the preceding sentence.
Executive agrees that he will not disclose or divulge to any third party, except
as may be required by his duties hereunder, by law, regulation, or order of a
court or government authority, or as directed by NBTB, nor shall he use to the
detriment of NBTB or its affiliates or use in any business or on behalf of any
business competitive with or substantially similar to any business of NBTB or
NBT Bank or their affiliates, any confidential business information obtained
during the course of his employment by NBTB.  The foregoing shall not be
construed as restricting Executive from disclosing such information to the
employees of NBTB or NBT Bank or their affiliates.  On or before the Termination
Date, Executive shall promptly deliver to NBTB any and all tangible,
confidential information in his position.


                                      II-44

          (b)  Executive  hereby  agrees  that  from the Commencement Date until
the first anniversary of the Termination Date, Executive will not (i) interfere
with the relationship of NBTB or NBT Bank or its affiliates with any of their
employees, suppliers, agents, or representatives (including, without limitation,
causing or helping another business to hire any employee of NBTB or NBT Bank or
its affiliates), or (ii) directly or indirectly divert or attempt to divert from
NBTB or NBT Bank or its affiliates any business in which any of them has been
actively engaged during the Term of Employment, nor interfere with the
relationship of NBTB or NBT Bank or its affiliates with any of their customers
or prospective customers.  This paragraph 4(b) shall not, in and of itself,
prohibit Executive from engaging in the banking, trust, or financial services
business in any capacity, including that of an owner or employee.

          (c)  Executive  acknowledges  and  agrees that irreparable injury will
result to NBTB in the event of a breach of any of the provisions of this section
4 (the "Designated Provisions") and that NBTB will have no adequate remedy at
law with respect thereto.  Accordingly, in the event of a material breach of any
Designated Provision, and in addition to any other legal or equitable remedy
NBTB may have, NBTB shall be entitled to the entry of a preliminary and
permanent injunction (including, without limitation, specific performance) by a
court of competent jurisdiction in Chenango County, New York, or elsewhere, to
restrain the violation or breach thereof by Executive, and Executive submits to
the jurisdiction of such court in any such action.

          (d)  It  is  the  desire and intent of the parties that the provisions
of this section 4 shall be enforced to the fullest extent permissible under the
laws and public policies applied in each jurisdiction in which enforcement is
sought.  Accordingly, if any particular provision of this section 4 shall be
adjudicated to be invalid or unenforceable, such provision shall be deemed
amended to delete therefrom the portion thus adjudicated to be invalid or
unenforceable, such deletion to apply only with respect to the operation of such
provision in the particular jurisdiction in which such adjudication is made.  In
addition, should any court determine that the provisions of this section 4 shall
be unenforceable with respect to scope, duration, or geographic area, such court
shall be empowered to substitute, to the extent enforceable, provisions similar
hereto or other provisions so as to provide to NBTB, to the fullest extent
permitted by applicable law, the benefits intended by this section 4.


     5.     Life Insurance.  In light of the unusual abilities and experience of
            --------------
Executive, NBTB in its discretion may apply for and procure as owner and for its
own benefit insurance on the life of Executive, in such amount and in such form
as NBTB may choose.  NBTB shall make all payments for such insurance and shall
receive all benefits from it.  Executive shall have no interest whatsoever in
any such policy or policies but, at the request of NBTB, shall submit to medical
examinations and supply such information and execute such documents as may
reasonably be required by the insurance company or companies to which NBTB has
applied for insurance.

     6.     Representations and Warranties.
            ------------------------------

          (a)  Executive  represents  and  warrants  to NBTB that his execution,
delivery, and performance of this Agreement will not result in or constitute a
breach of or conflict with any term, covenant, condition, or provision of any
commitment, contract, or other agreement or instrument, including, without
limitation, any other employment agreement, to which Executive is or has been a
party.

          (b)  Executive  shall  indemnify,  defend, and hold harmless NBTB for,
from, and against any and all losses, claims, suits, damages, expenses, or
liabilities, including court costs and counsel fees, which NBTB has incurred or
to which NBTB may become subject, insofar as such losses, claims, suits,
damages, expenses, liabilities, costs, or fees arise out of or are based upon
any failure of any representation or warranty of Executive in section 6(a)
hereof to be true and correct when made.

     7.     Notices.  All notices, consents, waivers, or other communications
            -------
which are required or permitted hereunder shall be in writing and deemed to have
been duly given if delivered personally or by messenger, transmitted by telex or
telegram, by express courier, or sent by registered or certified mail, return
receipt requested, postage prepaid.  All communications shall be addressed to
the appropriate address of each party as follows:

     8.     Assignment.  Neither party may assign this Agreement or any rights
            ----------
or obligations hereunder without the consent of the other party.

     9.     Governing Law.  This Agreement shall be governed by, construed, and
            -------------
enforced in accordance with the laws of the State of New York, without giving
effect to the principles of conflict of law thereof.  The parties hereby
designate Chenango County, New York to be the proper jurisdiction and venue for
any suit or action arising out of this Agreement.  Each of the parties consents
to personal jurisdiction in such venue for such a proceeding and agrees that it
may be served with process in any action with respect to this Agreement or the
transactions contemplated thereby by certified or registered mail, return
receipt requested, or to its registered agent for service of process in the
State of New York.  Each of the parties irrevocably and unconditionally waives
and agrees, to the fullest extent permitted by law, not to plead any objection
that it may now or hereafter have to the laying of venue or the convenience of
the forum of any action or claim with respect to this Agreement or the
transactions contemplated thereby brought in the courts aforesaid.

     10.     Entire Agreement.  This Agreement constitutes the entire
             ----------------
understanding among NBTB and Executive relating to the subject matter hereof.
Any previous agreements or understandings between the parties hereto or between
Executive and NBT Bank or any of its affiliates regarding the subject matter
hereof, including without limitation the terms and conditions of employment,
compensation, benefits, retirement, competition following employment, and the
like, are merged into and superseded by this Agreement.  Neither this Agreement
nor any provisions hereof can be modified, changed, discharged, or terminated
except by an instrument in writing signed by the party against whom any waiver,
change, discharge, or termination is sought.

     11.     Illegality; Severability.
             ------------------------

          (a)  Anything  in  this  Agreement  to  the  contrary notwithstanding,
this Agreement is not intended and shall not be construed to require any payment
to Executive which would violate any federal or state statute or regulation,
including without limitation the "golden parachute payment regulations" of the
Federal Deposit Insurance Corporation codified to Part 359 of title 12, Code of
Federal Regulations.

          (b)  If  any  provision  or provisions of this Agreement shall be held
to be invalid, illegal, or unenforceable for any reason whatsoever:

                    (i)  the  validity,  legality,  and  enforceability  of  the
remaining provisions of this Agreement (including, without limitation, each
portion of any section of this Agreement containing any such provision held to
be invalid, illegal, or unenforceable) shall not in any way be affected or
impaired thereby; and


                                      II-46

                    (ii) to  the fullest extent possible, the provisions of this
Agreement (including, without limitation, each portion of any section of this
Agreement containing any such provisions held to be invalid, illegal, or
unenforceable) shall be construed so as to give effect to the intent manifested
by the provision held invalid, illegal, or unenforceable.

     12.     Arbitration.  Subject to the right of each party to seek specific
             -----------
performance (which right shall not be subject to arbitration), if a dispute
arises out of or related to this Agreement, or the breach thereof, such dispute
shall be referred to arbitration in accordance with the Commercial Arbitration
Rules of the American Arbitration Association ("AAA").  A dispute subject to the
provisions of this section will exist if either party notifies the other party
in writing that a dispute subject to arbitration exists and states, with
reasonable specificity, the issue subject to arbitration (the "Arbitration
Notice").  The parties agree that, after the issuance of the Arbitration Notice,
the parties will try in good faith to resolve the dispute by mediation in
accordance with the Commercial Rules of Arbitration of AAA between the date of
the issuance of the Arbitration Notice and the date the dispute is set for
arbitration.  If the dispute is not settled by the date set for arbitration,
then any controversy or claim arising out of this Agreement or the breach hereof
shall be resolved by binding arbitration and judgment upon any award rendered by
arbitrator(s) may be entered in a court having jurisdiction.  Any person serving
as a mediator or arbitrator must have at least ten years' experience in
resolving commercial disputes through arbitration.  In the event any claim or
dispute involves an amount in excess of $100,000, either party may request that
the matter be heard by a panel of three arbitrators; otherwise all matters
subject to arbitration shall be heard and resolved by a single arbitrator.  The
arbitrator shall have the same power to compel the attendance of witnesses and
to order the production of documents or other materials and to enforce discovery
as could be exercised by a United States District Court judge sitting in the
Northern District of New York.  In the event of any arbitration, each party
shall have a reasonable right to conduct discovery to the same extent permitted
by the Federal Rules of Civil Procedure, provided that such discovery shall be
concluded within ninety days after the date the matter is set for arbitration.
In the event of any arbitration, the arbitrator or arbitrators shall have the
power to award reasonable attorney's fees to the prevailing party.  Any
