               (iii)  if  the  Termination  Date occurs during the first year of
the Term of Employment, then in consideration of Executive's past services,
Executive's agreement to provide consulting services under section 4 hereof, and
Executive's covenants under sections 5 and 6 hereof, Executive shall be entitled
to a lump-sum cash payment equal to $525,000;


                                      II-80

               (v)  if  the  Termination  Date  occurs  after the second year of
the Term of Employment, then in consideration of Executive's past services and
his covenants under sections 5 and 6 hereof, Executive shall be entitled to
receive a lump sum cash payment equal to the undiscounted amount of Executive's

          (d)  In  the  event  that the employment of Executive with NBT Bank is
terminated in any situation described in section 3 of the change-in-control
letter agreement dated as of OCTOBER 18, 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 notwithstanding the provisions of section 2 (c) hereof, Executive shall be
entitled to the following, and no more, under this section 2:

               (i)  any  salary  payable  pursuant  to  section  3(a)(i)  hereof

               (iii)  the  severance  payment  and  other  benefits  provided in

Notwithstanding the foregoing provisions of this section 2(d), the Executive may
at any time prior to the payment of any severance or other benefits under
section 3 of the Change-In-Control Agreement elect in writing to waive his
rights under the Change-in-Control Agreement, in which case this Agreement shall
apply to Executive without regard to the foregoing provisions of this section
2(d).  In the event that Executive becomes entitled to the severance and other

unless otherwise directed by the Executive in writing, no severance payments or
other benefits under section 3 of the Change in Control Agreement shall be paid
to Executive until ten business days after the providing of written notice by
NBTB to Executive.  If Executive does not waive his rights under the
Change-in-Control Agreement and receives severance or other benefits under
section 3 of the Change-in-Control Agreement, sections 4 and 5 of this Agreement
shall cease to apply and Executive shall have no obligation thereunder.

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

     4.   Consulting  Services
          -------------------

     (a) In the event that Executive's employment terminates hereunder during
the first two years of the Term of Employment and Executive becomes entitled to
a payment under either section 2(c)(iii) or 2(c)(iv) hereof, Executive shall,
during the Consulting Period (as hereinafter defined), be available to render
such consulting services to NBTB or NBT Bank as they may reasonably request of
Executive from time-to-time relating to their business and operations. The
services requested of Executive by NBTB and NBT Bank during the Consulting
Period shall be scheduled in consultation with Executive and shall be of a scope
so as to not materially interfere with Executive's engaging in full-time
employment after the Employment Term. NBTB or NBT Bank shall promptly reimburse
Executive for all expenses incurred by Executive in the performance of
Executive's consulting duties, including travel and subsistence expenses,
recognizing that Executive's home may not be in the geographic area where NBTB
and NBT Bank conduct business. Executive shall perform his duties under this
section 4(a) as an independent contractor to NBTB and NBT Bank.

     (b) For purposes of this Agreement, the term "Consulting Period" shall mean
(i) if Executive's employment terminates hereunder during the first year of the
Employment Term and Executive becomes entitled to the payment described in
section 2(c)(iii) hereof, the period beginning on the date of Executive's
termination of employment with NBT Bank and ending on the second anniversary of
such termination of employment, and (ii) if Executive's employment terminates
hereunder during the second year of the Employment Term and Executive becomes
entitled to the payment described in section 2(c)(iv) hereof, the period
beginning on the date of Executive's termination of employment with NBT Bank and
ending on the second anniversary of the Merger.

     (c) In consideration for Executive's covenants under this section 4 and
under sections 5 and 6 hereof, NBTB or NBT Bank shall, in addition to any lump
sum payment provided for by Section 2(c)(iii) and 2(c)(iv), as applicable,
provide to Executive for a three year period following the date of Executive's
termination of employment with NBT Bank, at no cost to Executive, life insurance
and health insurance (collectively, "Welfare Benefits") that are not less
favorable in all respects to those that Executive was receiving immediately
prior to the Termination Date; provided, however, that the medical coverage
provided shall be family medical coverage that also covers Executive's spouse
and any dependents. Executive will be entitled to elect to change his level of
coverage and/or his choice of coverage options with respect to the Welfare
Benefits provided by NBTB or NBT Bank to Executive to the same extent that
actively employed senior executives of NBTB and NBT Bank are permitted to make
such changes.

     5.   Covenant  Not  to  Compete.
          --------------------------

          (a)  The  parties acknowledge: (i) that as a result of the Merger, NBT
Bank and NBTB will be engaged in the business of banking in those markets where
CNB currently conducts its banking business; (ii) that Executive has developed
special expertise and a recognized reputation in CNB's markets and business; and
(iii) that if Executive were to undertake efforts in competition with NBT Bank
and NBTB in CNB's current market areas or solicit for employment officers of CNB
the result would be substantial and irreparable damage to NBT Bank and NBTB.

     (b) During the Restricted Period, Executive shall not solicit any business
(other than business in an area outside of twenty miles in which NBTB or any of
its subsidiaries is competitively engaged), customers or prospective customers
of NBTB or any of its subsidiaries whom Executive has served or solicited during
the course of his employment by CNB.

     (c) During the Restricted Period, Executive shall not, directly or
indirectly, either for Executive's own benefit or purpose or for the benefit or
purpose of any person or entity other than NBTB or any of its subsidiaries,
employ or offer to employ, call on, or actively interfere with NBTB's or any of
its subsidiaries' relationship with, or attempt to divert or entice away, any
officer of NBTB or any of its subsidiaries who was an officer of CNB or any of
its subsidiaries immediately prior to the Merger.

     (d) The term "Restricted Period shall mean (a) if there is a Consulting
Period, the period beginning on the first day of the Consulting Period and
ending on the first anniversary of the last day of the Consulting Period, and
(b) if there is no Consulting Period, the period beginning on Executive's
Termination Date and ending on the date that is six months after such
Termination Date.


                                      II-83

applicable, that is allocable to services or consideration provided by Executive
other than pursuant to Sections 4, 5 and 6 hereof is less than $135,000.

     6.   Confidential  Business  Information;  Non-Competition.
          -----------------------------------------------------

     (a) Executive acknowledges that certain business methods, creative
techniques, and technical data and the like of NBTB and its affiliates 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 CNB or their
affiliates, and compositions, ideas, plans, and methods belonging to or related
to the affairs of NBTB or CNB 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 CNB or their
affiliates, any confidential business information obtained during the course of
his employment by CNB or NBT Bank. The foregoing shall not be construed as
restricting Executive from disclosing such information to the employees of NBTB
or CNB or their affiliates. On or before the Termination Date, Executive shall
promptly deliver to NBTB any and all tangible, confidential information in his
possession.

     (b) Executive acknowledges and agrees that irreparable injury will result
to NBTB and its affiliates in the event of a breach of any of the provisions of
section 5 hereof or this section 6 (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, to restrain the violation or breach thereof by Executive, and
Executive submits to the jurisdiction of such court in any such action.

     (c) It is the desire and intent of the parties that the provisions of
section 5 hereof and this section 6 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 section
5 hereof or this section 6 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 section 5 hereof or this section 6 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 section 5 hereof and this section 6.

     7.   Life  Insurance.  In  light of the unusual abilities and experience of
          ---------------
Executive, NBTB or NBT Bank in their 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 or NBT Bank may choose.  NBTB or NBT Bank, as
applicable, 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 or NBT Bank, as applicable, 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 or NBT Bank, as applicable, has applied for insurance.

     8.   Representations  and  Warranties.
          --------------------------------

          (a)  Executive  represents  and  warrants  to NBTB that his execution,
delivery, and performance of the Agreement will not result in or constitute a
breach of 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 7(a) hereof to be true
and correct when made.

     10.  Assignment.  Neither  party  may  assign  this Agreement or any rights

or obligations hereunder without the consent of the other party.

     11.  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

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

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

transactions contemplated thereby brought in the courts aforesaid.

     12.  Entire  Agreement.  This  Agreement  constitutes  the  entire
          -----------------
understanding among NBTB, NBT Bank and Executive relating to the subject matter
hereof.  Any previous agreements or understandings between the parties hereto or
between Executive and CNB 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.

     13.  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) 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.

     14.  Arbitration.  Subject  to  the  right  of  each  party  hereto 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 provision in this Agreement to the contrary notwithstanding, this
section shall be governed by the Federal Arbitration Act and the parties have
entered into this Agreement pursuant to such Act.

     15.  Certain  Expenses.  NBTB  shall  pay  to  Executive all legal fees and
          -----------------
expenses (but not taxes, penalties or interest on taxes or penalties) incurred
by Executive (a) in seeking to obtain or enforce any provision of this Agreement
or (b) in connection with any tax audit or proceeding to the extent attributable
to the application of section 4999 of the Code to any payment or benefit
provided hereunder or under other plans and programs of CNB, NBTB or any of
their affiliates.  Such payments shall be made within five (5) business days
after delivery of Executive's written requests for payment accompanied with such
evidence of fees and expenses incurred as NBTB reasonably may require.



                                      II-86

     16.  Consent  to  Retirement  Annuity  Contribution.  NBTB hereby consents,
          ----------------------------------------------
for purposes of the Merger Agreement, to CNB taking all necessary and
appropriate actions prior to the Merger to (i) cause an aggregate of $25,000 to
be contributed to one or both of the annuity contracts (as specified by
Executive) held under the Supplemental Retirement Annuity Agreement (the "SRAA")
between Executive and CNB, dated May 15, 2000, (ii) cause the transfer of such
annuity contracts to a "rabbi trust," the terms of which shall provide for the
payment of benefits to Executive and his beneficiaries in accordance with the
terms of the SRAA, and (iii) amend the SRAA as necessary or appropriate to
reflect such actions.

     17.  Affiliation.  A  company  will  be deemed to be "affiliated" with NBTB
          -----------
or CNB according to the definition of "Affiliate" set forth in Rule 12b-2 of the
General Rules and Regulations under the Securities Exchange Act of 1934, as
amended.

     18.  Headings.  The  section  and  subsection  headings  herein  have  been
          --------
inserted for convenience of reference only and shall in no way modify or
restrict any of the terms or provisions hereof.

     19.  Termination.  This  Agreement  shall  terminate  in the event that the
          -----------
Merger Agreement terminates in accordance with Section 12 thereof.

     IN WITNESS WHEREOF, the parties hereto executed or caused this Agreement to
be executed as of the day and year first above written.
