EXHIBIT 10(b) AMENDMENT TO SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN --------------------------------------------------- Effective January 1, 2005 WHEREAS, ALLETE, Inc. (the "Company") maintains the ALLETE Supplemental Executive Retirement Plan (the "SERP" or "Plan"); and WHEREAS, the American Jobs Creation Act of 2004 added a new section 409A to the Internal Revenue Code establishing new rules regarding the taxation of non-qualified deferred compensation plans, effective for amounts deferred after December 31, 2004 (the "New Law"); and WHEREAS, under the new law, amounts deferred on and after January 1, 2005 under the SERP would be immediately taxable to participants; and WHEREAS, the Executive Compensation Committee of the Board of Directors of the Company has instructed management to prepare a new deferred compensation plan (a "New SERP") that will comply with the New Law to be adopted by the Company no later than December 31, 2005; and WHEREAS, recent guidance issued by the Internal Revenue Service specifies that bonuses earned by the SERP participants in 2004 that become payable in 2005 will, if subject to a deferral election, be treated as amounts deferred after December 31, 2004 for purposes of the New Law; and WHEREAS, such recent guidance also allows deferred compensation plans to be amended to give participants the opportunity to revoke, in whole or in part, certain outstanding elections to defer compensation; and WHEREAS, such recent guidance also allows participants to elect to defer certain performance-based compensation based on services performed over a period of at least 12 months no later than 6 months before the end of that period; and WHEREAS, it is desirable to preserve the deferral of taxes on 2004 bonuses, 2005 bonuses, and 2005 salary subject to deferral elections for SERP participants who do not revoke their elections to defer such compensation; and WHEREAS, it is therefore desirable to amend the SERP (1) to reflect the cessation of further deferrals thereunder after 2004; (2) to provide SERP participants with the opportunity to revoke their deferral elections for their 2004 bonuses and 2005 salary and make new deferral elections for their 2005 bonuses; and (3) to the extent that any such deferral elections are not so revoked, to redirect the deferral of 2004 deferred bonuses, 2005 deferred salary, and 2005 deferred bonuses to a new SERP. NOW, THEREFORE, effective as of January 1, 2005, the SERP is hereby amended as follows: 1. Article 4 of the SERP is hereby amended by adding the following new sections 4.16 and 4.17 to the end thereof: 4.16 CESSATION OF DEFERRALS. Notwithstanding any other Plan provision to the contrary, no amount of Annual Makeup Award, Salary Deferral, Bonus Deferral, Severance Deferral, Non-qualified Stock Option Gain Deferral, or Retirement Benefit (collectively "Deferral") earned for services performed in Plan years beginning after December 31, 2004 shall be deferred under this Plan. Accordingly, any election to make any Deferral under this plan shall terminate as to future Deferrals as of December 31, 2004 and shall no longer have any force or effect under this Plan. Subject to Section 4.17 hereof, Bonus Deferrals that were earned in 2004 and Deferrals earned in 2005, in each case, that are subject to Deferral elections made under the terms of this Plan shall not be credited under this Plan, but shall be credited under a new plan to be adopted in 2005 (a "New SERP") in accordance with the terms of the New SERP and shall be subject to the terms and conditions of such New SERP, including, without limitation, its distribution provisions. No new Deferral elections shall be made under this Article 4 with respect to amounts earned after December 31, 2004. Investment earnings (and losses) shall continue to be credited (or debited) to each participant's EDA account as provided in this Article 4. 4.17 OPPORTUNITY TO REVOKE ELECTION. Notwithstanding anything contained herein to the contrary, (i) any Participant who elected a 2004 Bonus Deferral may revoke his or her election in its entirety; (ii) any Participant who elected a 2005 Salary Deferral may revoke his or her election in part or in its entirety; and (iii) any Participant who elected a 2005 Bonus Deferral may file a new deferral election with respect to such 2005 Bonus Deferral, in each case as provided in this Section 4.17. Such revocation election with respect to 2004 Bonus Deferral and/or 2005 Salary Deferral or new deferral election with respect to 2005 Bonus Deferral must be in writing on a form provided by the administrator and must be filed with the administrator on or before January 28, 2005. Any participant who revokes his or her 2004 Bonus Deferral Election as provided herein shall receive such bonus in cash at or about the same time that such award is paid to other employees of the Company. Any Participant who revokes his or her 2005 Salary Deferral will be paid in accordance with the Company's standard payroll practices. IN WITNESS WHEREOF, ALLETE, Inc. has caused this instrument to be executed by its duly authorized officers. ALLETE, Inc. /s/ Donald J. Shippar ------------------------------------- Donald J.
