Exhibit 10.4 KEY EXECUTIVE EMPLOYMENT AND SEVERANCE AGREEMENT THIS AGREEMENT, made and entered into as of the ______ day of _________, ____ by and between Interstate Energy Corporation (d/b/a Alliant Energy Corporation), a Wisconsin corporation (hereinafter referred to as the "Company"), and [Executive Name] (hereinafter referred to as "Executive"). W I T N E S S E T H WHEREAS, the Executive is employed by the Company and/or a subsidiary of the Company (hereinafter referred to collectively as the "Employer") in a key executive capacity and the Executive's services are valuable to the conduct of the business of the Company; WHEREAS, the Company desires to continue to attract and retain dedicated and skilled management employees in a period of industry consolidation, consistent with achieving the best possible value for its shareowners in any change in control of the Company; WHEREAS, the Company recognizes that circumstances may arise in which a change in control of the Company occurs, through acquisition or otherwise, thereby causing a potential conflict of interest between the Company's needs for the Executive to remain focused on the Company's business and for the necessary continuity in management prior to and following a change in control, and the Executive's reasonable personal concerns regarding future employment with the Employer and economic protection in the event of loss of employment as a consequence of a change in control; WHEREAS, the Company and the Executive are desirous that any proposal for a change in control or acquisition of the Company will be considered by the Executive objectively and with reference only to the best interests of the Company and its shareowners; WHEREAS, the Executive will be in a better position to consider the Company's best interests if the Executive is afforded reasonable economic security, as provided in this Agreement, against altered conditions of employment which could result from any such change in control or acquisition; WHEREAS, the Executive possesses intimate knowledge of the business and affairs of the Company and has acquired certain confidential information and data with respect to the Company; and WHEREAS, the Company desires to insure, insofar as possible, that it will continue to have the benefit of the Executive's services and to protect its confidential information and goodwill.

If the Executive so elects and it is thereafter determined that Good Reason did exist, the Termination Date shall be the earliest of (i) the date on which the dispute is finally determined, either (x) by mutual written agreement of the parties or (y) in accordance with Section 22 hereof, (ii) the date of the Executive's death or (iii) one day prior to the end of the Employment Period. If the Executive so elects and it is thereafter determined that Good Reason did not exist, then the employment of the Executive hereunder shall continue after such determination as if the Executive had not delivered the Notice of Termination asserting Good Reason and there shall be no Termination Date arising out of such Notice. In either case, this Agreement continues, until the Termination Date, if any, as if the Executive had not delivered the Notice of Termination except that, if it is finally determined that Good Reason did exist, the Executive shall in no case be denied the benefits described in Sections 8(b) and 9 hereof (including a Termination Payment) based on events occurring after the Executive delivered his Notice of Termination. -12- (3) If an opinion is required to be delivered pursuant to Subsection 9(b)(ii) hereof and such opinion shall not have been delivered, the Termination Date shall be the earlier of the date on which such opinion is delivered or one day prior to the end of the Employment Period. (4) Except as provided in Subsection 1(l)(2) above, if the party receiving the Notice of Termination notifies the other party that a dispute exists concerning the termination within the appropriate period following receipt thereof and it is finally determined that the reason asserted in such Notice of Termination did not exist, then (1) if such Notice was delivered by the Executive, the Executive will be deemed to have voluntarily terminated his employment and the Termination Date shall be the earlier of the date fifteen days after the Notice of Termination is given or one day prior to the end of the Employment Period and (2) if delivered by the Company, the Company will be deemed to have terminated the Executive other than by reason of death, disability or Cause. 2. Termination or Cancellation Prior to Change in Control. (a) Subject to Subsection 2(b) hereof, the Employer and the Executive shall each retain the right to terminate the employment of the Executive at any time prior to a Change in Control of the Company. Subject to Subsection 2(b) hereof, in the event the Executive's employment is terminated prior to a Change in Control of the Company, this Agreement shall be terminated and cancelled and of no further force and effect, and any and all rights and obligations of the parties hereunder shall cease. -13- (b) Anything in this Agreement to the contrary notwithstanding, if a Change in Control of the Company occurs and if the Executive's employment with the Employer is terminated (other than a termination due to the Executive's death or as a result of the Executive's disability) during the period of 180 days prior to the date on which the Change in Control of the Company occurs, and if it is reasonably demonstrated by the Executive that such termination of employment (i) was at the request of a third party who has taken steps reasonably calculated to effect a Change in Control of the Company or (ii) otherwise arose in connection with or in anticipation of a Change in Control of the Company, then for all purposes of this Agreement such termination of employment shall be deemed a "Covered Termination," "Notice of Termination" shall be deemed to have been given, and the "Employment Period" shall be deemed to have begun on the date of such termination which shall be deemed to be the "Termination Date" and the date of the Change of Control of the Company for purposes of this Agreement. 3. Employment Period. If a Change in Control of the Company occurs when the Executive is employed by the Employer, the Employer will continue thereafter to employ the Executive during the Employment Period, and the Executive will remain in the employ of the Employer in accordance with and subject to the terms and provisions of this Agreement. Any termination of the Executive's employment during the Employment Period, whether by the Company or the Employer, shall be deemed a termination by the Company for purposes of this Agreement. 4. Duties. During the Employment Period, the Executive shall, in the same capacities and positions held by the Executive at the time of the Change in Control of the Company or in such other capacities and positions as may be agreed to by the Employer and the Executive in writing, devote the Executive's best efforts and all of the Executive's business time, attention and -14- skill to the business and affairs of the Employer, as such business and affairs now exist and as they may hereafter be conducted. The services which are to be performed by the Executive hereunder are to be rendered in the same metropolitan area in which the Executive was employed at the date of such Change in Control of the Company, or in such other place or places as shall be mutually agreed upon in writing by the Executive and the Employer from time to time. Without the Executive's consent, the Executive shall not be required to be absent from such metropolitan area more than 45 days in any fiscal year of the Company. 5. Compensation. During the Employment Period, the Executive shall be compensated as follows: (a) The Executive shall receive, at reasonable intervals (but not less often than monthly) and in accordance with such standard policies as may be in effect immediately prior to the Change in Control of the Company, an annual base salary in cash equivalent of not less than twelve times the Executive's highest monthly base salary for the twelve-month period immediately preceding the month in which the Change in Control of the Company occurs or, if higher, annual base salary at the rate in effect immediately prior to the Change in Control of the Company (which base salary shall, unless otherwise agreed in writing by the Executive, include the current receipt by the Executive of any amounts which, prior to the Change in Control of the Company, the Executive had elected to defer, whether such compensation is deferred under Section 401(k) of the Code or otherwise), subject to adjustment as hereinafter provided in Section 6 (such salary amount as adjusted upward from time to time is hereafter referred to as the "Annual Base Salary"). (b) The Executive shall receive fringe benefits at least equal in value to the highest value of such benefits provided for the Executive at any time during the 180-day period -15- immediately prior to the Change in Control of the Company or, if more favorable to the Executive, those provided generally at any time during the Employment Period to any executives of the Employer of comparable status and position to the Executive; and shall be reimbursed, at such intervals and in accordance with such standard policies that are most favorable to the Executive that were in effect at any time during the 180-day period immediately prior to the Change in Control of the Company, for any and all monies advanced in connection with the Executive's employment for reasonable and necessary expenses incurred by the Executive on behalf of the Employer, including travel expenses. (c) The Executive and/or the Executive's family, as the case may be, shall be included, to the extent eligible thereunder (which eligibility shall not be conditioned on the Executive's salary grade or on any other requirement which excludes persons of comparable status to the Executive unless such exclusion was in effect for such plan or an equivalent plan at any time during the 180-day period immediately prior to the Change in Control of the Company), in any and all plans providing benefits for the Employer's salaried employees in general, including but not limited to group life insurance, hospitalization, medical, dental, profit sharing and stock bonus plans; provided, that, (i) in no event shall the aggregate level of benefits under such plans in which the Executive is included be less than the aggregate level of benefits under plans of the Employer of the type referred to in this Subsection 5(c) in which the Executive was participating at any time during the 180-day period immediately prior to the Change in Control of the Company and (ii) in no event shall the aggregate level of benefits under such plans be less than the aggregate level of benefits under plans of the type referred to in this Subsection 5(c) provided at any time after the Change in Control of the Company to any executive of the Employer of comparable status and position to the Executive. -16- (d) The Executive shall annually be entitled to not less than the amount of paid vacation and not fewer than the highest number of paid holidays to which the Executive was entitled annually at any time during the 180-day period immediately prior to the Change in Control of the Company or such greater amount of paid vacation and number of paid holidays as may be made available annually to other executives of the Employer of comparable status and position to the Executive at any time during the Employment Period. (e) The Executive shall be included in all plans providing additional benefits to executives of the Employer of comparable status and position to the Executive, including but not limited to deferred compensation, split-dollar life insurance, supplemental retirement, stock option, stock appreciation, stock bonus and similar or comparable plans; provided, that, (i) in no event shall the aggregate level of benefits under such plans be less than the highest aggregate level of benefits under plans of the Employer of the type referred to in this Subsection 5(e) in which the Executive was participating at any time during the 180-day period immediately prior to the Change in Control of the Company; (ii) in no event shall the aggregate level of benefits under such plans be less than the aggregate levels of benefits under plans of the type referred to in this Subsection 5(e) provided at any time after the Change in Control of the Company to any executive of the Employer comparable in status and position to the Executive; and (iii) the Employer's obligation to include the Executive in bonus or incentive compensation plans shall be determined by Subsection 5(f) hereof. (f) To assure that the Executive will have an opportunity to earn incentive compensation after a Change in Control of the Company, the Executive shall be included in a bonus plan of the Employer which shall satisfy the standards described below (such plan, the "Bonus Plan"). Bonuses under the Bonus Plan shall be payable with respect to achieving such -17- financial or other goals reasonably related to the business of the Employer as the Employer shall establish (the "Goals"), all of which Goals shall be attainable, prior to the end of the Employment Period, with approximately the same degree of probability as the most attainable goals under the Employer's bonus plan or plans as in effect at any time during the 180-day period immediately prior to the Change in Control of the Company (whether one or more, the "Company Bonus Plan") and in view of the Employer's existing and projected financial and business circumstances applicable at the time. The amount of the bonus (the "Bonus Amount") that the Executive is eligible to earn under the Bonus Plan shall be no less than the amount of the Executive's maximum award provided in such Company Bonus Plan (such bonus amount herein referred to as the "Targeted Bonus"), and in the event the Goals are not achieved such that the entire Targeted Bonus is not payable, the Bonus Plan shall provide for a payment of a Bonus Amount equal to a portion of the Targeted Bonus reasonably related to that portion of the Goals which were achieved. Payment of the Bonus Amount shall not be affected by any circumstance occurring subsequent to the end of the Employment Period, including termination of the Executive's employment. 6. Annual Compensation Adjustments. During the Employment Period, the Board of Directors of the Company (or an appropriate committee thereof) will consider and appraise, at least annually, the contributions of the Executive to the Company, and in accordance with the Company's practice prior to the Change in Control of the Company, due consideration shall be given to the upward adjustment of the Executive's Annual Base Salary, at least annually, (i) commensurate with increases generally given to other executives of the Company of comparable status and position to the Executive, and (ii) as the scope of the Company's operations or the Executive's duties expand. -18- 7. Termination For Cause or Without Good Reason. If there is a Covered Termination for Cause or due to the Executive's voluntarily terminating his or her employment other than for Good Reason (any such terminations to be subject to the procedures set forth in Section 13 hereof), then the Executive shall be entitled to receive only Accrued Benefits pursuant to Subsection 9(a) hereof. 8. Termination Giving Rise to a Termination Payment. (a) If there is a Covered Termination by the Executive for Good Reason, or by the Company other than by reason of (i) death, (ii) disability pursuant to Section 12 hereof, or (iii) Cause (any such terminations to be subject to the procedures set forth in Section 13 hereof), then the Executive shall be entitled to receive, and the Company shall promptly pay, Accrued Benefits and, in lieu of further base salary for periods following the Termination Date, as liquidated damages and additional severance pay and in consideration of the covenant of the Executive set forth in Subsection 14(a) hereof, the Termination Payment pursuant to Subsection 9(b) hereof. (b) If there is a Covered Termination and the Executive is entitled to Accrued Benefits and the Termination Payment, then the Company shall provide to the Executive the following additional benefits: (i) The Executive shall receive, at the expense of the Company, outplacement services, on an individualized basis at a level of service commensurate with the Executive's status with the Company immediately prior to the date of the Change in Control of the Company (or, if higher, immediately prior to the termination of the Executive's employment), provided by a nationally recognized executive placement firm selected by the Company; provided that the cost to the Company of such services shall not exceed 10% of the Executive's Annual Base Salary. -19- (ii) Until the earlier of the end of the Employment Period or such time as the Executive has obtained new employment and is covered by benefits which in the aggregate are at least equal in value to the following benefits, the Executive shall continue to be covered, at the expense of the Company, by the same or equivalent life insurance, hospitalization, medical and dental coverage as was required hereunder with respect to the Executive immediately prior to the date the Notice of Termination is given. (iii) The Company shall cause the Executive to be fully and immediately vested in his accrued benefit under any supplemental executive retirement plan of the Employer providing benefits for the Executive (the "SERP") and in any defined contribution retirement plan of the Employer. In addition, the Company shall cause the Executive to be deemed to have satisfied any minimum years of service requirement under the SERP for subsidized early retirement benefits regardless of the Executive's age and service at the Termination Date; provided, however, that SERP benefits will be based on service to date with no additional credit for service or age beyond such Termination Date. (iv) The Company shall cause all restrictions on restricted stock awards made to the Executive to lapse such that the Executive is fully and immediately vested in his or her restricted stock. -20- (v) The Company shall cause all stock options granted to the Executive pursuant to the Company's stock option plan(s) to be fully vested. (vi) The Company shall cause all performance plan awards granted to the Executive pursuant to any long-term incentive plan maintained by the Company to be paid out at target, as if all performance requirements had been satisfied, on a pro rata basis based on the completed portion of each award cycle; provided, however, no payment of plan awards will occur from any award cycle that has been in effect less than six (6) months. 9. Payments Upon Termination. (a) Accrued Benefits. For purposes of this Agreement, the Executive's "Accrued Benefits" shall include the following amounts, payable as described herein: (i) all base salary for the time period ending with the Termination Date; (ii) reimbursement for any and all monies advanced in connection with the Executive's employment for reasonable and necessary expenses incurred by the Executive on behalf of the Employer for the time period ending with the Termination Date; (iii) any and all other cash earned through the Termination Date and deferred at the election of the Executive or pursuant to any deferred compensation plan then in effect; (iv) a lump sum payment of the bonus or incentive compensation otherwise payable to the Executive with respect to the year in which termination occurs under all bonus or incentive compensation plan or plans in which the Executive is a participant; and (v) all other payments and benefits to which the Executive (or in the event of the Executive's death, the Executive's surviving spouse or other beneficiary) may be entitled as compensatory fringe benefits or under the terms of any benefit plan -21- of the Employer, excluding severance payments under any Employer severance policy, practice or agreement in effect immediately prior to the Change in Control of the Company. Payment of Accrued Benefits shall be made promptly in accordance with the Company's prevailing practice with respect to Subsections (i) and (ii) or, with respect to Subsections (iii), (iv) and (v), pursuant to the terms of the benefit plan or practice establishing such benefits. (b) Termination Payment. (i) Subject to the limits set forth in Subsection 9(b)(ii) hereof, the Termination Payment shall be an amount equal to (A) the Executive's Annual Base Salary (determined as of the time of the Change in Control of the Company or, if higher, immediately prior to the date the Notice of Termination is given) plus (B) an amount equal to the greater of the Executive's target bonus for the year in which the Termination Date occurs or the bonus the Executive received in the year prior to the Change in Control of the Company (the aggregate amount set forth in (A) and (B) hereof shall hereafter be referred to as "Annual Cash Compensation"), times (C) the number of years or fractional portion thereof remaining in the Employment Period determined as of the Termination Date; provided, however, that such amount shall not be less than the greater of (i) the amount of the Executive's Annual Cash Compensation or (ii) the severance benefits to which the Executive would have been entitled under the Company's severance policies and practices in effect immediately prior to the Change in Control of the Company. The Termination Payment shall be paid to the Executive in cash equivalent ten (10) business days after the -22- Termination Date. Such lump sum payment shall not be reduced by any present value or similar factor, and the Executive shall not be required to mitigate the amount of the Termination Payment by securing other employment or otherwise, nor will such Termination Payment be reduced by reason of the Executive securing other employment or for any other reason. The Termination Payment shall be in lieu of, and acceptance by the Executive of the Termination Payment shall constitute the Executive's release of any rights of Executive to, any other severance payments under any Company severance policy, practice or agreement. The Company shall bear up to $10,000 in the aggregate of fees and expenses of consultants and/or legal or accounting advisors engaged by the Executive to advise the Executive as to matters relating to the computation of benefits due and payable under this Subsection 9(b). (ii) Notwithstanding any other provision of this Agreement, if any portion of the Termination Payment or any other payment under this Agreement, or under any other agreement with or plan of the Employer (in the aggregate, "Total Payments"), would constitute an "excess parachute payment," then the Total Payments to be made to the Executive shall be reduced such that the value of the aggregate Total Payments that the Executive is entitled to receive shall be One Dollar ($1) less than the maximum amount which the Executive may receive without becoming subject to the tax imposed by Section 4999 of the Code (or any successor provision) or which the Company may pay without loss of deduction under -23- Section 280G(a) of the Code (or any successor provision). For purposes of this Agreement, the terms "excess parachute payment" and "parachute payments" shall have the meanings assigned to them in Section 280G of the Code (or any successor provision), and such "parachute payments" shall be valued as provided therein. Present value for purposes of this Agreement shall be calculated in accordance with Section 1274(b) (2) of the Code (or any successor provision). Within forty days following a Covered Termination or notice by the Company to the Executive of its belief that there is a payment or benefit due the Executive which will result in an excess parachute payment as defined in Section 280G of the Code (or any successor provision), the Executive and the Company, at the Company's expense, shall obtain the opinion (which need not be unqualified) of nationally recognized tax counsel ("National Tax Counsel") selected by the Company's independent auditors and reasonably acceptable to the Executive (which may be regular outside counsel to the Company), which opinion sets forth (A) the amount of the Base Period Income, (B) the amount and present value of Total Payments and (C) the amount and present value of any excess parachute payments determined without regard to the limitations of this Subsection 9(b)(ii). As used in this Subsection 9(b)(ii), the term "Base Period Income" means an amount equal to the Executive's "annualized includable compensation for the base period" as defined in Section 280G(d)(l) of the Code. For purposes of such opinion, the value of any noncash benefits or any deferred payment or benefit shall be determined -24- by the Company's independent auditors in accordance with the principles of Sections 280G(d)(3) and (4) of the Code (or any successor provisions), which determination shall be evidenced in a certificate of such auditors addressed to the Company and the Executive. The opinion of National Tax Counsel shall be addressed to the Company and the Executive and shall be binding upon the Company and the Executive. If such National Tax Counsel opinion determines that there would be an excess parachute payment, the Termination Payment hereunder or any other payment or benefit determined by such counsel to be includable in Total Payments shall be reduced or eliminated as specified by the Executive in writing delivered to the Company within thirty days of his receipt of such opinion or, if the Executive fails to so notify the Company, then as the Company shall reasonably determine, so that under the bases of calculations set forth in such opinion there will be no excess parachute payment. If such National Tax Counsel so requests in connection with the opinion required by this Section, the Executive and the Company shall obtain, at the Company's expense, and the National Tax Counsel may rely on, the advice of a firm of recognized executive compensation consultants as to the reasonableness of any item of compensation to be received by the Executive solely with respect to its status under Section 280G of the Code and the regulations thereunder. (iii) If, notwithstanding the provisions of Subsection (ii) of this Subsection 9(b) it is ultimately determined by a court or pursuant to a -25- final determination by the Internal Revenue Service that any portion of Total Payments is subject to the tax (the "Excise Tax") imposed by Section 4999 of the Code (or any successor provision), the Company shall pay to the Executive an additional amount (the "Gross-Up Payment") such that the net amount retained by the Executive after deduction of any Excise Tax and any interest charges or penalties in respect of the imposition of such Excise Tax (but not any federal, state or local income tax) on the Total Payments, and any federal, state and local income tax and Excise Tax upon the payment provided for by this Subsection (iii), shall be equal to the Total Payments. For purposes of determining the amount of the Gross-Up Payment, the Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation in the calendar year in which the Gross-Up Payment is to be made and state and local income taxes at the highest marginal rates of taxation in the state and locality of the Executive's domicile for income tax purposes on the date the Gross-Up Payment is made, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes. (iv) The Company agrees to bear all costs associated with, and to indemnify and hold harmless, the National Tax Counsel of and from any and all claims, damages, and expenses resulting from or relating to its determinations pursuant to this Subsection 9(b), except for claims, damages or expenses resulting from the gross negligence or willful misconduct of such firm. -26- 10. Death. (a) Except as provided in Section 10(b) hereof, in the event of a Covered Termination due to the Executive's death, the Executive's estate, heirs and beneficiaries shall receive all the Executive's Accrued Benefits through the Termination Date. (b) In the event the Executive dies after a Notice of Termination is given (i) by the Company or (ii) by the Executive for Good Reason, the Executive's estate, heirs and beneficiaries shall be entitled to the benefits described in Subsection 10(a) hereof and, subject to the provisions of this Agreement, to such Termination Payment as the Executive would have been entitled to had the Executive lived. For purposes of this Subsection 10(b), the Termination Date shall be the earlier of thirty days following the giving of the Notice of Termination, subject to extension pursuant to Subsection 1(l) hereof, or one day prior to the end of the Employment Period. 11. Retirement. If, during the Employment Period, the Executive and the Employer shall execute an agreement providing for the early retirement of the Executive from the Employer, or the Executive shall otherwise give notice that he is voluntarily choosing to retire early from the Employer, the Executive shall receive Accrued Benefits through the Termination Date; provided, that if the Executive's employment is terminated by the Executive for Good Reason or by the Company other than by reason of death, disability or Cause and the Executive also, in connection with such termination, elects voluntary early retirement, the Executive shall also be entitled to receive a Termination Payment pursuant to Subsection 8(a) hereof. 12. Termination for Disability. If, during the Employment Period, as a result of the Executive's disability due to physical or mental illness or injury (regardless of whether such illness or injury is job-related), the Executive shall have been absent from the Executive's duties hereunder on a full-time basis for a period of six consecutive months and, within thirty days after -27- the Company notifies the Executive in writing that it intends to terminate the Executive's employment (which notice shall not constitute the Notice of Termination contemplated below), the Executive shall not have returned to the performance of the Executive's duties hereunder on a full-time basis, the Company may terminate the Executive's employment for purposes of this Agreement pursuant to a Notice of Termination given in accordance with Section 13 hereof. If the Executive's employment is terminated on account of the Executive's disability in accordance with this Section, the Executive shall receive Accrued Benefits in accordance with Subsection 9(a) hereof and shall remain eligible for all benefits provided by any long term disability programs of the Company in effect at the time of such termination. 13. Termination Notice and Procedure. Any Covered Termination by the Company or the Executive (other than a termination of the Executive's employment that is a Covered Termination by virtue of Subsection 2(b) hereof) shall be communicated by a written notice of termination ("Notice of Termination") to the Executive, if such Notice is given by the Company, and to the Company, if such Notice is given by the Executive, all in accordance with the following procedures and those set forth in Section 23 hereof: (a) If such termination is for disability, Cause or Good Reason, the Notice of Termination shall indicate in reasonable detail the facts and circumstances alleged to provide a basis for such termination. (b) Any Notice of Termination by the Company shall have been approved, prior to the giving thereof to the Executive, by a resolution duly adopted by a majority of the directors of the Company (or any successor corporation) then in office. (c) If the Notice is given by the Executive for Good Reason, the Executive may cease performing his duties hereunder on or after the date fifteen days after the -28- delivery of Notice of Termination and shall in any event cease employment on the Termination Date. If the Notice is given by the Company, then the Executive may cease performing his duties hereunder on the date of receipt of the Notice of Termination, subject to the Executive's rights hereunder. (d) The Executive shall have thirty days, or such longer period as the Company may determine to be appropriate, to cure any conduct or act, if curable, alleged to provide grounds for termination of the Executive's employment for Cause under this Agreement pursuant to Subsection 1(d) (iii) hereof. (e) The recipient of any Notice of Termination shall personally deliver or mail in accordance with Section 23 hereof written notice of any dispute relating to such Notice of Termination to the party giving such Notice within fifteen days after receipt thereof; provided, however, that if the Executive's conduct or act alleged to provide grounds for termination by the Company for Cause is curable, then such period shall be thirty days. After the expiration of such period, the contents of the Notice of Termination shall become final and not subject to dispute. 14. Further Obligations of the Executive. (a) Competition. The Executive agrees that, in the event of any Covered Termination where the Executive is entitled to Accrued Benefits and the Termination Payment, the Executive shall not, for a period expiring one year after the Termination Date, without the prior written approval of the Company's Board of Directors, participate in the management of, be employed by or own any business enterprise at a location within the United States that engages in substantial competition with the Company or its subsidiaries, where such enterprise's revenues from any competitive activities amount to 10% or more of such enterprise's net revenues and sales for its most recently completed fiscal year; provided, however, that nothing -29- in this Subsection 14(a) shall prohibit the Executive from owning stock or other securities of a competitor amounting to less than five percent of the outstanding capital stock of such competitor. (b) Confidentiality. During the Executive's employment by the Company and for a period of five (5) years thereafter, the Executive shall hold in confidence and not directly or indirectly disclose or use or copy or make lists of any confidential information or proprietary data of the Company (including that of the Employer), except to the extent authorized in writing by the Board of Directors of the Company or required by any court or administrative agency, other than to an employee of the Company or a person to whom disclosure is reasonably necessary or appropriate in connection with the performance by the Executive of duties as an executive of the Company. Confidential information shall not include any information known generally to the public or any information of a type not otherwise considered confidential by persons engaged in the same business or a business similar to that of the Company. All records, files, documents and materials, or copies thereof, relating to the business of the Company which the Executive shall prepare, or use, or come into contact with, shall be and remain the sole property of the Company and shall be promptly returned to the Company upon termination of employment with the Company. 15. Expenses and Interest. If, after a Change in Control of the Company, (i) a dispute arises with respect to the enforcement of the Executive's rights under this Agreement or (ii) any legal or arbitration proceeding shall be brought to enforce or interpret any provision contained herein or to recover damages for breach hereof, in either case so long as, and to the extent that, the Executive prevails in such proceeding, the Executive shall recover from the Company the reasonable attorneys' fees and necessary costs and disbursements incurred as a result of the dispute, legal or arbitration proceeding as to which the Executive has prevailed -30- ("Expenses"), and prejudgment interest on any money judgment or arbitration award obtained by the Executive calculated at the rate of interest announced by Firstar Bank Milwaukee, N. A., Milwaukee, Wisconsin, from time to time at its prime or base lending rate from the date that payments to him or her should have been made under this Agreement. Any dispute as to the reasonableness of the Expenses incurred, or the extent to which the Executive has prevailed, shall be resolved by the presiding officer (arbitrator or judge) in the forum in which the substantive issues are finally resolved. 16. Payment Obligations Absolute. The Company's obligation during and after the Employment Period to pay the Executive the amounts and to make the benefit and other arrangements provided herein shall be absolute and unconditional and shall not be affected by any circumstances, including, without limitation, any setoff, counterclaim, recoupment, defense or other right which the Company may have against him or anyone else. Except as provided in Section 15 of this Agreement, all amounts payable by the Company hereunder shall be paid without notice or demand. Each and every payment made hereunder by the Company shall be final, and the Company will not seek to recover all or any part of such payment from the Executive, or from whomsoever may be entitled thereto, for any reason whatsoever. 17. Successors. (a) If the Company sells, assigns or transfers all or substantially all of its business and assets to any Person or if the Company merges into or consolidates or otherwise combines (where the Company does not survive such combination) with any Person (any such event, a "Sale of Business"), then the Company shall assign all of its right, title and interest in this Agreement as of the date of such event to such Person, and the Company shall cause such Person, by written agreement in form and substance reasonably satisfactory to the Executive, to expressly assume and agree to perform from and after the date of such assignment all -31- of the terms, conditions and provisions imposed by this Agreement upon the Company. Failure of the Company to obtain such agreement prior to the effective date of such Sale of Business shall be a breach of this Agreement constituting "Good Reason" hereunder, except that for purposes of implementing the foregoing the date upon which such Sale of Business becomes effective shall be deemed the Termination Date. In case of such assignment by the Company and of assumption and agreement by such Person, as used in this Agreement, "Company" shall thereafter mean such Person which executes and delivers the agreement provided for in this Section 17 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law, and this Agreement shall inure to the benefit of, and be enforceable by, such Person. The Executive shall, in his or her discretion, be entitled to proceed against any or all of such Persons, any Person which theretofore was such a successor to the Company and the Company (as so defined) in any action to enforce any rights of the Executive hereunder. Except as provided in this Subsection, this Agreement shall not be assignable by the Company. This Agreement shall not be terminated by the voluntary or involuntary dissolution of the Company. (b) This Agreement and all rights of the Executive shall inure to the benefit of and be enforceable by the Executive's personal or legal representatives, executors, administrators, heirs and beneficiaries. All amounts payable to the Executive under Sections 7, 8, 9, 10, 11, 12 and 15 hereof if the Executive had lived shall be paid, in the event of the Executive's death, to the Executive's estate, heirs and representatives; provided, however, that the foregoing shall not be construed to modify any terms of any benefit plan of the Employer, as such terms are in effect on the date of the Change in Control of the Company, that expressly govern benefits under such plan in the event of the Executive's death. -32- 18. Severability. The provisions of this Agreement shall be regarded as divisible, and if any of said provisions or any part hereof are declared invalid or unenforceable by a court of competent jurisdiction, the validity and enforceability of the remainder of such provisions or parts hereof and the applicability thereof shall not be affected thereby. 19. Contents of Agreement; Waiver of Rights; Amendment. This Agreement sets forth the entire understanding between the parties hereto with respect to the subject matter hereof and shall supersede in all respects, and the Executive hereby waives all rights under, any prior or other agreement or understanding between the parties with respect to such subject matter, including, but not limited to the [previous Key Executive Employment and Severance Agreement dated as of _______ between Company and the Executive.] This Agreement may not be amended or modified at any time except by written instrument executed by the Company and the Executive. 20. Withholding. The Company shall be entitled to withhold from amounts to be paid to the Executive hereunder any federal, state or local withholding or other taxes or charges which it is from time to time required to withhold; provided, that the amount so withheld shall not exceed the minimum amount required to be withheld by law. The Company shall be entitled to rely on an opinion of the National Tax Counsel if any question as to the amount or requirement of any such withholding shall arise. 21. Certain Rules of Construction. No party shall be considered as being responsible for the drafting of this Agreement for the purpose of applying any rule construing ambiguities against the drafter or otherwise. No draft of this Agreement shall be taken into account in construing this Agreement. Any provision of this Agreement which requires an agreement in -33- writing shall be deemed to require that the writing in question be signed by the Executive and an authorized representative of the Company. 22. Governing Law; Resolution of Disputes. This Agreement and the rights and obligations hereunder shall be governed by and construed in accordance with the laws of the State of Wisconsin. Any dispute arising out of this Agreement shall, at the Executive's election, be determined by arbitration under the rules of the American Arbitration Association then in effect (in which case both parties shall be bound by the arbitration award) or by litigation. Whether the dispute is to be settled by arbitration or litigation, the venue for the arbitration or litigation shall be Madison, Wisconsin or, at the Executive's election, if the Executive is not then residing or working in the Madison, Wisconsin metropolitan area, in the judicial district encompassing the city in which the Executive resides; provided, that, if the Executive is not then residing in the United States, the election of the Executive with respect to such venue shall be either Madison, Wisconsin or in the judicial district encompassing that city in the United States among the thirty cities having the largest population (as determined by the most recent United States Census data available at the Termination Date) which is closest to the Executive's residence. The parties consent to personal jurisdiction in each trial court in the selected venue having subject matter jurisdiction notwithstanding their residence or situs, and each party irrevocably consents to service of process in the manner provided hereunder for the giving of notices. 23.
