For purposes of this calculation, Years of Credited Service and Years of Participation shall continue to accrue during the period of Disability and the Participant's Final Average Earnings will be calculated based on the Participant's earnings history as of the date of the disability. PAGE 10 - EXECUTIVE SURVIVOR AND SUPPLEMENTAL RETIREMENT PLAN 5.5 Payment of Benefits (a) FORM OF BENEFIT PAYMENT. The Supplemental Retirement Benefit shall be paid in the form of a monthly single life annuity with a fifteen (15) year certain period.

Participants may select, as an alternative form, a fifty percent (50%) Joint and Survivor benefit which shall be the Actuarial Equivalent to the monthly single-life annuity with a fifteen (15) year certain period. For the Beneficiaries of executive officers, the remaining benefit, if any, shall be paid in addition to the benefits provided in 4.4. For Beneficiaries of other key management employees, this shall be the only benefit payable, if any. (b) COMMENCEMENT OF BENEFIT PAYMENTS.

Such distribution shall completely discharge the Committee and the Employer from all liability with respect to such benefit. ARTICLE VI--BENEFICIARY DESIGNATION 6.1 Beneficiary Designation Each Participant shall have the right, at any time, to designate any person or persons as Beneficiary (both primary as well as secondary) to whom benefits under this Plan shall be paid as a result of the Participant's death prior to complete distribution to Participant of the benefits due under the Plan.

The Board may amend this Plan at any time or from time to time. Any amendment may provide different benefits or amounts of benefits from those herein set forth. However, no such termination, suspension or amendment shall adversely affect the benefits of Participants which have accrued prior to such action or the benefits of any Beneficiary of a Participant who has previously died. PAGE 14 - EXECUTIVE SURVIVOR AND SUPPLEMENTAL RETIREMENT PLAN ARTICLE X--MISCELLANEOUS 10.1 Unfunded Plan This Plan is intended to be an unfunded plan maintained primarily to provide deferred compensation benefits for a select group of management or highly compensated employees. 10.2 Unsecured General Creditor In the event of Employer's insolvency, Participants and their Beneficiaries, heirs, successors and assigns shall have no legal or equitable rights, interest or claims in any property or assets of Employer, nor shall they be Beneficiaries of, or have any rights, claims or interests in any life insurance policies, annuity contracts or the proceeds therefrom owned or which may be acquired by Employer. In that event, any and all of Employer's assets and policies shall be, and remain, the general, unpledged, unrestricted assets of Employer. Employer's obligation under the Plan shall be that of an unfunded and unsecured promise of Employer to pay money in the future. 10.3 Trust Fund Employer shall be responsible for the payment of all benefits provided under the Plan. At its discretion, Employer may establish one or more trusts, with such trustees as the Board may approve, for the purpose of providing for the payment of such benefits. Such trust or trusts may be irrevocable, but the assets thereof shall be subject to the claims of Employer's creditors. To the extent any benefits provided under the Plan are actually paid from any such trust, Employer shall have no further obligation with respect thereto, but to the extent not so paid, such benefits shall remain the obligation of, and shall be paid by, Employer. 10.4 Nonassignability Neither a Participant nor any other person shall have any right to commute, sell, assign, transfer, pledge, anticipate, mortgage or otherwise encumber, transfer, hypothecate or convey in advance of actual receipt the amounts, if any, payable hereunder, or any part thereof, which are, and all rights to which are, expressly declared to be unassignable and nontransferable. No part of the amounts payable shall, prior to actual payment, be subject to seizure or sequestration for the payment of any debts, judgments, alimony or separate maintenance owed by a Participant or any other person, nor be transferable by operation of law in the event of a Participant's or any other person's bankruptcy or insolvency. 10.5 Not a Contract of Employment The terms and conditions of this Plan shall not be deemed to constitute a contract of employment between Employer and the Participant, and the Participant (or the Participant's Beneficiary) shall have no rights against Employer except as may otherwise be specifically provided herein. Moreover, nothing in this Plan shall be deemed to give a Participant the right to be retained in the service of Employer or to interfere with the right of Employer to discipline or discharge the Participant at any time. PAGE 15 - EXECUTIVE SURVIVOR AND SUPPLEMENTAL RETIREMENT PLAN 10.6 Protective Provisions A Participant will cooperate with Employer by furnishing any and all information requested by Employer, in order to facilitate the payment of benefits hereunder, and by taking such physical examinations as Employer may deem necessary and taking such other action as may be requested by Employer. 10.7 Terms Wherever any words are used herein in the singular or in the plural, they shall be construed as though they were used in the plural or the singular, as the case may be, in all cases where they would so apply. 10.8 Captions The captions of the articles, sections and paragraphs of this Plan are for convenience only and shall not control or affect the meaning or construction of any of its provisions. 10.9 Governing Law The provisions of this Plan shall be construed and interpreted according to the laws of the State of Minnesota. 10.10 Validity In case any provision of this Plan shall be held illegal or invalid for any reason, said illegality or invalidity shall not affect the remaining parts hereof, but this Plan shall be construed and enforced as if such illegal and invalid provision had never been inserted herein. 10.11 Notice Any notice or filing required or permitted to be given to the Committee under the Plan shall be sufficient if in writing and hand delivered, or sent by registered or certified mail to any member of the Committee or the Secretary of the Employer. Such notice shall be deemed given as of the date of delivery or, if delivery is made by mail, as of the date shown on the postmark on the receipt for registration or certification. 10.12 Successors The provisions of this Plan shall bind and inure to the benefit of Otter Tail Corporation and its successors and assigns.
