Any Retirement Income Benefit paid from the Plan in a form other than a life annuity shall be the actuarial equivalent of a life annuity, utilizing the actuarial equivalent factors set forth in the Basic Retirement Plan and applied to obtain the optional mode of payment thereunder. The Committee, in its sole discretion and consistent with the best interests of the Employer may distribute any Retirement Income Benefit and 401(k)/ESOP Benefit payable under the Plan to a Participant, beneficiary, joint or contingent annuitant, or eligible child, as a single lump sum benefit, using, in the case of a Retirement Income Benefit, the actuarial equivalent factors set forth in the Basic Retirement Plan for lump-sum cashouts. In exercising its discretion hereunder, the Committee shall not be bound by any request by a Participant, beneficiary, joint or contingent annuitant, or eligible child, to receive any Retirement Income Benefit and 401(k)/ESOP Benefit payable under the Plan as a single lump-sum benefit. 7.2 Except with respect to receipt of a lump sum benefit under Section 7.1, any elections for an optional mode of benefit payment made by a Participant under the Basic Retirement Plan and the Basic 401(k)/ESOP, shall also be effective with respect to any Retirement Income Benefit and 401(k)/ESOP Benefit, as the case may be, payable under the Plan to a Participant, beneficiary, joint or contingent annuitant, or eligible child. 7.3 Except with respect to receipt of a lump sum benefit under Section 7.1, payment of any Retirement Income Benefit and 401(k)/ESOP Benefit under the Plan shall commence on the same date as payment of a Basic Retirement Plan and 401(k)/ESOP Plan distribution payable to a Participant or beneficiary, and shall terminate on the date of last payment of Basic Retirement Plan and 401(k)/ESOP Plan distribution, as the case may be. 7.4 The Supplemental Retirement Benefit shall be paid: (a) except as provided in Section 7.4(b) (early retirement) and Section 8.6 (death), commencing on the first day of the month following the later of the Participant's retirement or his or her attainment of age 62; or (b) commencing on the first day of the month following the Participant's Determination Date in connection with early retirement after reaching age 60 and prior to the date of his or her 62nd birthday. 7.5 The Supplemental Retirement Benefit shall be paid in the form specified below: (a) The Supplemental Retirement Benefit shall be paid as a straight life annuity, payable in monthly installments, for the Participant's life; provided, however, that if the Participant has no surviving spouse and dies before having received 60 monthly payments, such monthly payments shall be continued to his or her Beneficiary until the total number of monthly payments to the Participant and his or her Beneficiary equal 60, whereupon all payments shall cease and the Company's obligation to pay the Supplemental Retirement Benefit under shall be deemed to have been fully discharged. If the Participant and his or her Beneficiary shall die before having received a total of 60 monthly payments, an amount equal to the Actuarial Equivalent of the balance of such monthly payments shall be paid in a single sum to the estate of the survivor of the Participant and his or her Beneficiary. If Supplemental Retirement Benefits are payable in the form described in this Section 7.5(a), the Participant shall designate in writing, as his or her Beneficiary, any person or persons, primarily, contingently or successively, to whom the Company shall pay benefits following the Participant's death if the Participant's death occurs before 60 monthly payments have been made. (b) Notwithstanding the form of payment described in Section 7.5(a), if the Participant is married on the date payment of the Supplemental Retirement Benefit commences, the benefit shall be paid as a 50% joint and survivor annuity with the Participant's spouse as the Beneficiary. The 50% joint and survivor annuity shall be the Actuarial Equivalent of the benefit described in Section 7.5(a). If the Supplemental Retirement Benefit is payable pursuant to this Section 7.5(a), but the Participant's spouse fails to survive him or her, no payments of the Supplement Retirement Benefit will be made following the Participant's death. (c) Notwithstanding the foregoing provisions of this Section 7.5, the Company, in its sole discretion, may accelerate the payment of all or any portion of the Supplemental Retirement Benefit or the reduced early Supplemental Retirement Benefit at any time. Any payment accelerated in accordance with this Section 7.5(c) shall be the Actuarial Equivalent of the payment being accelerated. 7.6 Subject to Section 12.4, each Participant shall have a 100 percent vested and non-forfeitable right to benefits under the Plan. ARTICLE 8 DEATH BENEFITS 8.1 Upon the death of: (i) a Participant who has not terminated from employment before Retirement Date as defined in Section 3.1, or (ii) a Participant who retires on a Retirement Date as defined in Section 3.1 and dies before the complete distribution of Basic Retirement Plan Benefit and Basic 401(k)/ESOP Benefit, as the case may be, benefits shall be payable as set forth in Sections 8.2, 8.3 and 8.4. 8.2 With respect to any Retirement Income Benefit, if a Basic Retirement Plan pre-retirement survivor annuity or post retirement survivor annuity, as the case may be, is payable to a Participant's surviving spouse or eligible children, if applicable, a supplemental pre-retirement survivor annuity or post retirement survivor annuity, as the case may be, shall be payable to the surviving spouse or eligible children, if applicable, under the Plan. The monthly amount of the Supplemental Surviving Spouse Benefit pre-retirement survivor annuity or post retirement survivor annuity, as the case may be, payable to a surviving spouse or eligible children, if applicable, shall be equal to the excess, if any, of the amount specified in (a) over the amount specified in (b), as stated below: (a) the monthly amount of Basic Retirement Plan pre-retirement survivor annuity or post retirement survivor annuity, as the case may be, to which the surviving spouse or eligible children, if applicable, would have been entitled under the Basic Retirement Plan, if such benefit were calculated under the Basic Retirement Plan without giving effect to the limitations and restrictions imposed by the Plan Limitation Provisions and any other provisions of the Basic Retirement Plan that are necessary to comply with Code Sections 401(a)(17) and 415, or any successor provisions thereto; (b) (i) the monthly amount of Basic Retirement Plan pre-retirement survivor annuity or post retirement survivor annuity, as the case may be, actually payable to the surviving spouse or eligible children, if applicable, under the Basic Retirement Plan, after the limitations imposed by the application of Plan Limitation Provisions and any other provisions of the Basic Retirement Plan that are necessary to comply with Code Sections 401(a)(17) and 415, or any successor provisions thereto plus (ii) the monthly amount that is the actuarial equivalent (determined in accordance with the Basic Retirement Plan) of any supplemental retirement benefit payable to the surviving spouse or eligible children, if applicable, by any Employer following the Participant's death pursuant to any Supplemental Retirement Agreement with the Participant. 8.3 The Retirement Income Benefit supplemental pre-retirement survivor annuity or post retirement survivor annuity shall be payable over the lifetime of the surviving spouse, or to eligible children to the extent provided in the Basic Retirement Plan, in monthly installments commencing on the same date as payment of the Basic Retirement Plan pre-retirement survivor annuity or post retirement survivor annuity, as the case may be, and shall terminate on the date of the last payment of the Basic Retirement Plan pre-retirement survivor annuity or post retirement survivor annuity, as the case may be. 8.4 With respect to any 401(k)/ESOP Benefit, all amounts credited to the Participant's Deferral Credit Account shall be payable in a single lump sum to the Participant's surviving spouse, if any, as a Supplemental Surviving Spouse Benefit, unless an optional mode has been elected pursuant to Article 7. 8.5 Upon the death of a Participant under the circumstances set forth in clauses (i) and (ii) of Section 8.1, if no Basic Retirement Plan Surviving Spouse Benefit, or Basic 401(k)/ESOP Surviving Spouse Benefit, as the case may be, is payable, (a) no further Retirement Income Benefit shall be payable, unless an optional mode has been elected pursuant to Article 7, and (b) all amounts credited to the Participant's Deferral Credit Account shall be payable to the Participant's designated beneficiary in a single lump sum, unless an optional mode has been elected pursuant to Article 7. 8.6 The following provisions shall apply with respect to payment of the Supplemental Retirement Benefit after the death of a Participant: (a) Except as provided in Section 8.6(b), if a Participant shall die before his or her 62nd birthday, no Supplemental Retirement Benefit shall be payable. (b) If a Participant shall die on or after his or her 60th birthday, after he or she has retired but before payment of any Supplemental Retirement Benefit has commenced, the Participant's surviving spouse, if any, shall be paid as a straight life annuity 50 percent of the Supplemental Retirement Benefit for her life commencing within 30 days following the Participant's death. Such payments shall be made in monthly installments, subject to the right of the Company to accelerate payment at any time in accordance with Section 7.5(c). However, if such Participant is not married at the time of his or her death, the Company shall pay to the Participant's Beneficiary a lump sum benefit equal to 50 percent of the Present Value of the Participant's Supplemental Retirement Benefit. (c) Except as provided in Section 8.6(b), no Supplemental Retirement Benefit shall be payable if the Participant dies before payment of any Supplement Retirement Benefit has begun without having a spouse who survives him or her. (d) If a Participant dies after payment of a Supplemental Retirement Benefit has commenced, the amount, if any, of the Supplemental Retirement Benefit payable to the Participant's surviving spouse or other Beneficiary shall be determined pursuant to the applicable provisions of Section 7.5. ARTICLE 9 UNFUNDED PLAN 9.1 The Plan shall be administered as an unfunded plan and is not intended to meet the qualification requirements of Sections 401(a) and 401(k) of the Code. No Participant or beneficiary shall be entitled to receive any payment or benefits under the Plan from the qualified trust maintained in connection with the Basic Retirement Plan and Basic 401(k)/ESOP. 9.2 The Employer shall have the right to establish a reserve, establish a grantor trust or make any investment for the purposes of satisfying its obligation hereunder for payment of benefits, including, but not limited to, investments in one or more registered investment companies under the Investment Company Act of 1940, as amended, to the extent permitted by applicable banking or other law; provided, however, that no Participant or beneficiary shall have any interest in such investment, trust, or reserve. 9.3 To the extent that any Participant or beneficiary acquires a right to receive benefits under the Plan, such rights shall be no greater than those rights which guarantee to the Participant or beneficiary the strongest claim to such benefits, without resulting in the Participant's or beneficiary's constructive receipt of such benefits. 9.4 With respect to any 401(k)/ESOP Benefit, 100% of the Participant's Deferral Credit Account shall be deemed to be invested as provided in Section 5.4 above. A Participant's Deferral Credit Account may not be encumbered or assigned by a Participant or any beneficiary. 9.5 A Participant or beneficiary with a Retirement Income Benefit, the 401(k)/ESOP Benefit or both such Benefits under the Plan shall be an unsecured creditor of the Employer as to any benefit payable under the Plan. 9.6 Not later than the closing of any transaction that would constitute a Change of Control, the Employer shall transfer to an independent corporate trustee of a grantor trust within the meaning of section 671 of the Code that satisfies the applicable requirements of Revenue Procedure 92-64 or any successor thereto an amount sufficient to cover all potential liabilities under this Plan. ARTICLE 10 ADMINISTRATION 10.1 Except for the functions reserved to the Company or the Board, the administration of the Plan shall be the responsibility of the Committee. The Committee shall consist of three or more persons designated by the Company. Members of the Committee shall serve for such terms as the Company shall determine and until their successors are designated and qualified. Any member of the Committee may resign upon at least 60 days written notice to the Company, or may be removed from office by the Company at any time, with or without notice. 10.2 The Committee shall hold meetings upon notice at such times and places as it may determine. Notice shall not be required if waived in writing. Any action of the Committee shall be taken pursuant to a majority vote at a meeting, or pursuant to the written consent of a majority of its members without a meeting, and such action shall constitute the action of the Committee and shall be binding in the same manner as if all members of the Committee had joined therein. A majority of the members of the Committee shall constitute a quorum. No member of the Committee shall note or be counted for quorum purposes on any matter relating solely to himself or herself or his or her rights under the Plan. The Committee shall record minutes of any actions taken at its meetings or of any other official action of the Committee. Any person dealing with the Committee shall be fully protected in relying upon any written notice, instruction, direction or other communication signed by the Secretary of the Committee or by any of the members of the Committee or by a representative of the Committee authorized by the Committee to sign the same in its behalf. 10.3 The Committee shall have the power and the duty to take all actions and to make all decisions necessary or proper to carry out the Plan. The determination of the Committee as to any question involving the Plan shall be final, conclusive and binding. Any discretionary actions to be taken under the Plan by the Committee shall be uniform in their nature and applicable to all persons similarly situated. Without limiting the generality of the foregoing, the Committee shall have the following powers and duties: (a) the duty to furnish to all Participants, upon request, copies of the Plan; (b) the power to require any person to furnish such information as it may request for the purpose of the proper administration of the Plan as a condition to receiving any benefits under the Plan; (c) the power to make and enforce such rules and regulations and prescribe the use of such forms as it shall deem necessary for the efficient administration of the Plan; (d) the power to interpret the Plan, and to resolve ambiguities, inconsistencies and omissions, which findings shall be binding, final and conclusive; (e) the power to decide on questions concerning the Plan in accordance with the provisions of the Plan; (f) the power to determine the amount of benefits which shall be payable to any person in accordance with the provisions of the Plan and to provide a full and fair review to any Participant whose claim for benefits has been denied in whole or in part; (g) the power to designate a person who may or may not be a member of the Committee as Plan "Administrator" for purposes of the Employee Retirement Income Security Act of 1974 (ERISA); if the Committee does not so designate an Administrator, the Committee shall be the Plan Administrator; (h) the power to allocate any such powers and duties to or among individual members of the Committee; and (i) the power to designate persons other than Committee members to carry out any duty or power which would otherwise be a responsibility of the Committee or Administrator, under the terms of the Plan. 10.4 To the extent permitted by law, the Committee and any person to whom it may delegate any duty or power in connection with administering the Plan, the Company, any Employer, and the officers and directors thereof, shall be entitled to rely conclusively upon, and shall be fully protected in any action taken or suffered by them in good faith in the reliance upon, any actuary, counsel, accountant, other specialist, or other person selected by the Committee, or in reliance upon any tables, valuations, certificates, opinions or reports which shall be furnished by any of them. Further, to the extent permitted by law, no member of the Committee, nor the Company, any Employer, nor the officers or directors thereof, shall be liable for any neglect, omission or wrongdoing of any other members of the Committee, agent, officer or employee of the Company or any Employer. Any person claiming benefits under the Plan shall look solely to the Employer for redress. 10.5 All expenses incurred before the termination of the Plan that shall arise in connection with the administration of the Plan (including, but not limited to administrative expenses, proper charges and disbursements, compensation and other expenses and charges of any actuary, counsel, accountant, specialist, or other person who shall be employed by the Committee in connection with the administration of the Plan), shall be paid by the Employer. ARTICLE 11 AMENDMENT OR TERMINATION 11.1 The Board shall have the power to suspend or terminate the Plan in whole or in part at any time, and from time to time to extend, modify, amend or revise the Plan in such respects as the Board, by resolution, may deem advisable; provided, however, that no such extension, modification, amendment, revision, or termination shall deprive a Participant or any beneficiary of any benefit accrued under the Plan. 11.2 In the event of a termination or partial termination of the Plan, the rights of all affected parties, if any, to benefits accrued to the date of such termination or partial termination, shall become nonforfeitable to the same extent that such rights would be nonforfeitable if such benefits were provided under the Basic Retirement Plan or the Basic 401(k)/ESOP and such plans were terminated on such date. 11.3 No amendment of the Plan shall reduce the vested and accrued benefits, if any, of a Participant under this Plan, except to the extent that such a reduction would be permitted if such benefits were provided under the Basic Retirement Plan or the Basic 401(k)/ESOP. 11.4 In the event of the termination or partial termination of the Plan: (a) the Company shall pay in one lump sum to affected Participants or their beneficiaries the 401(k)/ESOP Benefit, if any, to which they are entitled, as if such Participants' termination of service had occurred on the date the Plan is terminated, and (b) the Retirement Income Benefit and Supplemental Retirement Benefit, if any, to which they are entitled shall continue to be payable. ARTICLE 12 GENERAL PROVISIONS 12.1 The Plan shall not be deemed to constitute an employment contract between the Employer and any Employee or other person, whether or not in the employ of the Employer, nor shall anything herein contained be deemed to give any Employee or other person, whether or not in the employ of the Employer, any right to be retained in the employ of the Employer, or to interfere with the right of the Employer to discharge any Employee at any time and to treat such Employee without any regard to the effect which such treatment might have upon such Employee as a Participant of the Plan. 12.2 Except as provided in Section 12.4, or as may otherwise be required by law, no distribution or payment under the Plan to any Participant or beneficiary shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge, whether voluntary or involuntary, and any attempt to so anticipate, alienate, sell, transfer, assign, pledge, encumber or charge the same shall be void; nor shall any such distribution or payment be in any way liable for or subject to the debts, contracts, liabilities, engagements or torts of any person entitled to such distribution or payment. If any Participant or beneficiary is adjudicated bankrupt or purports to anticipate, alienate, sell, transfer, assign, pledge, encumber or charge any such distribution or payment, voluntarily or involuntarily, the Committee, in its sole discretion, may cancel such distribution or payment or may hold or cause to be held or applied such distribution or payment, or any part thereof, to or for the benefit of such Participant or beneficiary, in such manner as the Committee shall direct. 12.3 If the Employer determines that any person entitled to payments under the Plan is incompetent by reason of physical or mental disability, it may cause all payments thereafter becoming due to such person to be made to any other person for his or her benefit, without responsibility to follow application of amounts so paid. Payments made pursuant to this provision shall completely discharge the Plan, the Employer and the Committee. 12.4 Notwithstanding any other provision of this Plan: (a) if the Employer determines that Cause exists for the termination of the Participant's employment, the Participant and his or her spouse and beneficiaries shall forfeit all rights to any payments under this Plan; (b) if a Participant separates from service before having completed five Years of Service with any Employer, no Supplemental Retirement Benefit shall be payable hereunder; (c) no amounts shall be payable hereunder to the Participant and his or her spouse and beneficiaries: (i) following any breach by the Participant of any provision of any employment or other written agreement with the Company, the Bank or any other Employer with respect to confidentiality, non-competition, non-interference with, or non-solicitation of, employees, customers, suppliers or agents or similar matters, provided that no Change in Control shall have occurred before such breach; (ii) if, without the prior written consent of the Company, the Participant discloses or divulges to any third party, except as may be required by his or her duties, by law, regulation, or order of a court or government authority, or as directed by the Company, or uses to the detriment of the Company or its affiliates or in any business or on behalf of any business competitive with or substantially similar to any business of the Company or the Bank or their affiliates, any Confidential Information obtained during the course of his or her employment by the Company, the Bank or any affiliate of any of either of them, provided that this Section 12.4(c)(ii) shall not be construed as restricting the Participant from disclosing such information to the employees of the Company or the Bank or their affiliates; (iii) if while the Participant is employed by the Company, the Bank, any Employer or any affiliate of any of them or within two years after any termination of such employment other than in anticipation of or following a Change in Control, the Participant (A) interferes with the relationship of the Company, the Bank or their affiliates with any of their employees, suppliers, agents, or representatives (including, without limitation, causing or helping another business to hire any employee of the Company, the Bank or their affiliates), or (B) directly or indirectly diverts or attempts to divert from the Company, the Bank or their affiliates any business in which any of them has been actively engaged during the period of such employment, or interferes with the relationship of the Company, the Bank or their affiliates with any of their customers or prospective customers, provided, that this Section 12.4(c)(iii) shall not, in and of itself, prohibit the Participant from engaging in the banking, trust, or financial services business in any capacity, including that of an owner or employee; and (d) if any particular provision of this section 12.4 shall be adjudicated to be invalid or unenforceable, such provision shall be deemed amended to delete from 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 12.4 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 the Company, the Bank and their affiliates, to the fullest extent permitted by applicable law, the benefits intended by this section 12.4. 12.5 The Employer shall be the sole source of benefits under the Plan, and each Employee, Participant, beneficiary, or any other person who shall claim the right to any payment or benefit under the Plan shall be entitled to look solely to the Employer for payment of benefits. 12.6 If the Employer is unable to make payment to any Participant, beneficiary, or any other person to whom a payment is due under the Plan, because it cannot ascertain the identity or whereabouts of such Participant, beneficiary, or other person after reasonable efforts have been made to identify or locate such person (including a notice of the payment so due mailed to the last known address of such Participant, beneficiary, or other person shown on the records of the Employer), such payment and all subsequent payments otherwise due to such Participant, beneficiary or other person shall be forfeited 24 months alter the date such payment first became due; provided, however, that such payment and any subsequent payments shall be reinstated, retroactively, no later than 60 days after the date on which the Participant, beneficiary, or other person shall make application therefor. Neither the Company, the Committee nor any other person shall have any duty or obligation under the Plan to make any effort to locate or identify any person entitled to benefits under the Plan, other than to mail a notice to such person's last known mailing address. 12.7 If upon the payment of any benefits under the Plan, the Employer shall be required to withhold any amounts with respect to such payment by reason of any federal, state or local tax laws, rules or regulations, then the Employer shall be entitled to deduct and withhold such amounts from any such payments. In any event, such person shall make available to the Employer, promptly when requested by the Employer, sufficient funds or other property to meet the requirements of such withholding. Furthermore, at any time the Employer shall be obligated to withhold taxes, the Employer shall be entitled to take and authorize such steps as it may deem advisable in order to have the amounts required to be withheld made available to the Employer out of any funds or property due to become due to such person, whether under the Plan or otherwise. 12.8 The Committee, in its discretion, may increase or decrease the amount of any benefit payable hereunder if and to the extent that it determines, in good faith, that an increase is necessary in order to avoid the omission of a benefit intended to be payable under this Plan or that a decrease is necessary in order to avoid a duplication of the benefits intended to be payable under this Plan. 12.9 The provisions of the Plan shall be construed, administered and governed under applicable federal laws and the laws of the State of New York. In applying the laws of the State of New York, no effect shall be given to conflict of laws principles that would cause the laws of another jurisdiction to apply. NBT BANCORP INC.
