EMPLOYMENT AGREEMENT OF JAMES J. HOWARD THIS AGREEMENT by and between Northern States Power Company, a Minnesota corporation (the "Company"), and James J. Howard (the "Executive"), dated as of the 24th day of March, 1999. WITNESSETH THAT WHEREAS, the Company and New Century Energies, Inc., a Delaware corporation ("NCE"), have entered into an Agreement and Plan of Merger dated as of March 24, 1999 (the "Merger Agreement"), whereby NCE will merge with and into the Company (the "Merger"); WHEREAS, the Board of Directors of the Company (the "Board") recognizes that the Executive would, absent the Merger, be expected to retire on or about July 1, 2000; and WHEREAS, the Board has determined that it is critical to the successful consummation of the Merger that the Executive remain employed by the Company through the first anniversary of the Merger, in order to ensure that the necessary regulatory approvals of the Merger be obtained, and to help implement a successful transition to combined operations of the Company and NCE; WHEREAS, the Company and NCE wish to provide for the orderly succession of management of the surviving company in the Merger (the "Company") following the Effective Time (as defined in the Merger Agreement); and WHEREAS, in light of the foregoing, the Company and NCE further wish to provide for the employment by the Company of the Executive, and the Executive wishes to serve the Company, in the capacities and on the terms and conditions set forth in this Agreement; NOW, THEREFORE, it is hereby agreed as follows: 1. EFFECT ON PRIOR AGREEMENTS; EMPLOYMENT PERIOD. (a) The Executive is currently employed as President and Chief Executive Officer of the Company and Chairman of the Board pursuant to a Summary of Terms and Conditions of Employment, amended and restated as of January 28, 1998 (the "Prior Agreement"). The Prior Agreement shall remain in effect without amendment until the Effective Time, except as specified herein. (b) From the Effective Time through the first anniversary thereof (the "Employment Period"), the Company shall employ the Executive, and the Executive shall serve the Company, on the terms and conditions set forth in this Agreement. (c) Notwithstanding any other provision of this Agreement, if the Merger Agreement is terminated without consummation of the Merger, the Executive shall retire upon the later of the date the Merger Agreement is so terminated and July 1, 2001, and this Agreement shall be null and void and of no further force or effect, except as specifically set forth in Section 3(c)(i) and Section 3(e) below. 2. POSITION AND DUTIES; LOCATION. (a) During the Employment Period, the Executive shall continue to serve as Chairman of the Board. In such capacity, the Executive shall be an employee of the Company and shall have such duties and responsibilities as are customarily assigned to such positions, and such other duties and responsibilities not inconsistent therewith as may from time to time be assigned to him by the Board. (b) During the Employment Period as is customary, the Executive shall report to the Board. (c) During the Employment Period, and excluding any periods of vacation and sick leave to which the Executive is entitled, the Executive shall devote reasonable attention and time during normal business hours to the business and affairs of the Company and, to the extent necessary to discharge the responsibilities assigned to the Executive under this Agreement, use the Executive's reasonable best efforts to carry out such responsibilities faithfully and efficiently. It shall not be considered a violation of the foregoing for the Executive to serve on corporation, industry, civic or charitable boards or committees, so long as such activities do not significantly interfere with the performance of the Executive's responsibilities as an employee of the Company in accordance with this Agreement. (d) The Executive's service shall be performed at the Company's headquarters in Minneapolis, Minnesota. 3. COMPENSATION. (a) BASE SALARY. The Executive's compensation during the Employment Period shall be determined by the Board upon the recommendation of the Compensation Committee of the Board, subject to the next sentence and Section 3(b). During the Employment Period, the Executive shall receive an annual base salary ("Annual Base Salary") at least equal to his annual base salary as in effect immediately before the Effective Time (and in any event not less than $730,000). The Annual Base Salary shall be payable in accordance with the Company's regular payroll practice for its senior executives, as in effect from time to time. Any increase in the Annual Base Salary shall not limit or reduce any other obligation of the Company under this Agreement. (b) INCENTIVE COMPENSATION. During the Employment Period, the Executive shall also be eligible for annual bonuses on the same terms and conditions as other senior executives of the Company; PROVIDED, that the Executive's target annual bonus (the "Target Bonus") shall equal 65 percent of the Annual Base Salary. -2- (c) OTHER BENEFITS. (i) SUPPLEMENTAL RETIREMENT BENEFIT. Upon the termination of the Executive's employment for any reason after the date of this Agreement, the Executive shall receive a supplemental retirement benefit (the "SERP Benefit"), computed as follows. The amount of the SERP Benefit shall be such that the Executive's combined benefits from the Northern States Power Company Pension Plan (the "Pension Plan"), the Company's Deferred Compensation Plan (defined benefit portion) and Excess Benefit Plan (such plans, together, the "Nonqualified Pension Plans"), and the SERP Benefit shall equal the benefit the Executive would have received under the Pension Plan and the Nonqualified Pension Plans if he had completed 30 years of service; PROVIDED, however, that the SERP Benefit shall be reduced (but not below zero) by the excess, if any, of the annual retirement benefits of $151,296 he earned from Ameritech over the annual retirement benefit that the Pension Plan's actuaries reasonably estimate is equivalent to the accumulated value, at the time the Executive's pension benefit payments begin, of the monthly benefit payments he would have received under the Pension Plan and the Nonqualified Pension Plans prior to that time if monthly benefit payments had commenced at the end of the month following the month he attained age 60. The SERP Benefit shall be paid in a lump sum at retirement. The amount of the lump sum shall be determined using the interest rate for valuing immediate annuities used by the Pension Benefit Guaranty Corporation at January 1 of the year in which such payment is being made, or if no such rate has been established then the PBGC rate in effect for the previous December, and the mortality rates to be used shall be the mortality rates set forth in the Appendix to the Pension Plan in effect at the time the payment is made. Notwithstanding the foregoing, if the date of the Executive's termination of employment is after July 1, 2000, the amount of the lump sum shall be computed as if the Executive's termination employment had occurred on July 1, 2000, and the actual SERP Benefit paid shall equal such amount, plus interest thereon during the period from July 1, 2000 through the date of actual payment, at a rate equal to the interest rate on long-term Treasury obligations in effect during such period. The SERP Benefit as described herein is a restatement of, and shall replace, the benefit provided for in Section 13 of the Prior Agreement. (ii) During the Employment Period, the Company shall provide the Executive with life insurance coverage providing a death benefit to such beneficiary or beneficiaries as the Executive may designate of not less than five times his Annual Base Salary. (iii) In addition, and without limiting the generality of the foregoing, during the Employment Period and thereafter: (A) the Executive shall be entitled to participate in all applicable incentive, savings and retirement plans, practices, policies and programs of the Company and its subsidiaries to the same extent as other senior executives of the Company; and (B) the Executive and/or the Executive's family, as the case may be, shall be eligible for participation in, and shall receive all benefits under, all applicable welfare benefit plans, practices, policies and programs provided by the Company and its subsidiaries, other than severance plans, practices, policies and programs but including, without limitation, medical, prescription, dental, disability, sick leave, employee life insurance, group life insurance, accidental death and travel accident insurance plans and programs, to the same extent as other -3- senior executives of the Company (but excluding the Company's Senior Executive Severance Policy and 1999 Senior Executive Severance Policy (the "Severance Policies")). (d) FRINGE BENEFITS; VACATION. During the Employment Period, the Executive shall be entitled to receive fringe benefits on the same terms and conditions as the greater of (i) the fringe benefits received by, or available to, him from the Company immediately before the Effective Time, or (ii) the fringe benefits provided by the Company or its subsidiaries which are available to the Chief Executive Officer of the Company. Without limiting the generality of the foregoing, the Executive shall receive six weeks of vacation per year accrued on a pro rata basis, and the same paid holidays and sick leave as is made available to other full-time benefit non-union employees of the Company; payment of monthly dues at the Minneapolis Club as well as for a country club of his choice; a fully-equipped leased American car of his choice and a heated garage space at work; PROVIDED, that personal travel outside the Company territory will be subject to reimbursement at the rates periodically established by the Company; and an annual physical by a doctor of his choice and a reasonable allowance for financial planning expenses, including tax and asset management, as requested by the Executive. (e) SPECIAL RETENTION BONUS. In recognition of the Executive's remaining employed through the end of the Employment Period, and his special efforts to cause the Merger to take place and to implement a successful transition to combined operations of the Company and NCE, the Company shall pay the Executive a special cash bonus (the "Special Retention Bonus"), as provided in this Section 3(e). If the Merger is consummated and the Executive remains employed through the end of the Employment Period, the Special Retention Bonus shall equal $7,600,000, and shall be paid on the last day of the Employment Period; and if the Merger Agreement is terminated without consummation of the Merger, or the Executive's employment is terminated because of the Executive's death or Disability before the last day of the Employment Period, the Special Retention Bonus shall equal $2,500,000 and shall be paid on the day that the Executive's employment terminates; PROVIDED, that if after receiving the Special Retention Bonus, the Executive commits any material breach of the covenants set forth in Section 8 below, he shall be obligated to return $2,500,000 of such Special Retention Bonus to the Company. 4. TERMINATION OF EMPLOYMENT. (a) DEATH OR DISABILITY. The Executive's employment shall terminate automatically upon the Executive's death during the Employment Period. The Company shall be entitled to terminate the Executive's employment because of the Executive's Disability during the Employment Period. "Disability" means that (i) the Executive has been unable, for a period of 180 consecutive business days, to perform the Executive's duties under this Agreement, as a result of physical or mental illness or injury, and (ii) a physician selected by the Company or its insurers, and acceptable to the Executive or the Executive's legal representative, has determined that the Executive's incapacity is total and permanent. A termination of the Executive's employment by the Company for Disability shall be communicated to the Executive by written notice, and shall be effective on the 30th day after receipt of such notice by -4- the Executive (the "Disability Effective Date") unless the Executive returns to full-time performance of the Executive's duties before the Disability Effective Date. (b) BY THE COMPANY. (i) The Company may terminate the Executive's employment during the Employment Period for Cause or without Cause. "Cause" means: A. the willful and continued failure of the Executive substantially to perform the Executive's duties under this Agreement (other than as a result of physical or mental illness or injury), after the Board of the Company delivers to the Executive a written demand for substantial performance that specifically identifies the manner in which the Board believes that the Executive has not substantially performed the Executive's duties; or B. illegal conduct or gross misconduct by the Executive, in either case that is willful and results in material and demonstrable damage to the business or reputation of the Company. No act or failure to act on the part of the Executive shall be considered "willful" unless it is done, or omitted to be done, by the Executive in bad faith or without reasonable belief that the Executive's action or omission was in the best interests of the Company. Any act or failure to act that is based upon authority given pursuant to a resolution duly adopted by the Board, or the advice of counsel for the Company, shall be conclusively presumed to be done, or omitted to be done, by the Executive in good faith and in the best interests of the Company. (ii) A termination of the Executive's employment for Cause shall be effected in accordance with the following procedures. The Company shall give the Executive written notice ("Notice of Termination for Cause") of its intention to terminate the Executive's employment for Cause, setting forth in reasonable detail the specific conduct of the Executive that it considers to constitute Cause and the specific provision(s) of this Agreement on which it relies, and stating the date, time and place of the Special Board Meeting for Cause. The "Special Board Meeting for Cause" means a meeting of the Board called and held specifically for the purpose of considering the Executive's termination for Cause, that takes place not less than ten and not more than twenty business days after the Executive receives the Notice of Termination for Case. The Executive shall be given an opportunity, together with counsel, to be heard at the Special Board Meeting for Cause. The Executive's termination for Cause shall be effective when and if a resolution is duly adopted at the Special Board Meeting for Cause by an affirmative vote of at least the greater of (A) two-thirds (2/3) of the entire membership of the Board (excluding the Executive who shall not vote on this matter) or (B) ten (10) members of the Board, stating that in the good faith opinion of the Board, the Executive is guilty of the conduct described in the Notice of Termination for Cause, and that conduct constitutes Cause under this Agreement. -5- (iii) A termination of the Executive's employment without Cause shall be effective in accordance with the following procedures. The Company shall give the Executive written notice ("Notice of Termination without Cause") of its intention to terminate the Executive's employment without Cause, stating the date, time and place of the Special Board Meeting without Cause. The "Special Board Meeting without Cause" means a meeting of the Board called and held specifically for the purpose of considering the Executive's termination without Cause, that takes place not less than ten and not more than twenty business days after the Executive receives the Notice of Termination without Cause. The Executive shall be given an opportunity, together with counsel, to be heard at the Special Board Meeting without Cause. The Executive's termination without Cause shall be effective when and if a resolution is duly adopted at the Special Board Meeting without Cause by an affirmative vote of the greater of (A) at least two-thirds (2/3) of the entire membership of the Board (excluding the Executive who shall not vote on this matter) or (B) ten members of the Board stating that the Executive is terminated without Cause. (c) GOOD REASON. (i) The Executive may terminate employment for Good Reason or without Good Reason. "Good Reason" means: A. the assignment to the Executive of any duties inconsistent in any respect with paragraph (a) of Section 2 of this Agreement, or any other action by the Company that results in a diminution in the Executive's position, authority, duties or responsibilities, other than an isolated, insubstantial and inadvertent action that is not taken in bad faith and is remedied by the Company promptly after receipt of notice thereof from the Executive; B. any failure by the Company to comply with any provision of Section 3 of this Agreement, other than an isolated, insubstantial and inadvertent failure that is not taken in bad faith and is remedied by the Company promptly after receipt of notice thereof from the Executive; C. the assignment or reassignment by the Company of the Executive without the Executive's consent to another place of employment more than 50 miles from the Company's headquarters indicated in Section 2(d); D. any purported termination of the Executive's employment by the Company for a reason or in a manner not expressly permitted by this Agreement; E. any failure by the Company to comply with paragraph (c) of Section 11 of this Agreement; or -6- F. any other substantial breach of this Agreement by the Company that either is not taken in good faith or is not remedied by the Company promptly after receipt of notice thereof from the Executive. The Company and the Executive, upon mutual written Agreement, may waive any of the foregoing provisions which would otherwise constitute Good Reason. (ii) A termination of employment by the Executive for Good Reason shall be effectuated by giving the Company written notice ("Notice of Termination for Good Reason") of the termination, setting forth in reasonable detail the specific conduct of the Company that constitutes Good Reason and the specific provision(s) of this Agreement on which the Executive relies. A termination of employment by the Executive for Good Reason shall be effective on the fifth business day following the date when the Notice of Termination for Good Reason is given, unless the notice sets forth a later date (which date shall in no event be later than 30 days after the notice is given). For purposes of this Section 4(c), any good faith determination of "Good Reason" made by the Executive shall be conclusive. (iii) A termination of the Executive's employment by the Executive without Good Reason shall be effected by giving the Company written notice of the termination. (d) NO WAIVER. The failure to set forth any fact or circumstance in a Notice of Termination for Cause, a Notice of Termination without Cause or a Notice of Termination for Good Reason shall not constitute a waiver of the right to assert, and shall not preclude the party giving notice from asserting, such fact or circumstance in an attempt to enforce any right under or provision of this Agreement. (e) DATE OF TERMINATION. The "Date of Termination" means the date of the Executive's death, the Disability Effective Date, the date on which the termination of the Executive's employment by the Company for Cause or without Cause or by the Executive for Good Reason is effective, or the date on which the Executive gives the Company notice of a termination of employment without Good Reason, as the case may be. 5. OBLIGATIONS OF THE COMPANY UPON TERMINATION. (a) BY THE COMPANY OTHER THAN FOR CAUSE OR DISABILITY; BY THE EXECUTIVE FOR GOOD REASON. If, during the Employment Period, the Company terminates the Executive's employment other than for Cause or Disability, or the Executive terminates employment for Good Reason, the Company shall continue to provide the Executive with the compensation and benefits set forth in paragraphs (a), (b), (c) and (e) of Section 3, other than benefits under defined benefit pension plans, as if he had remained employed by the Company pursuant to this Agreement through the end of the Employment Period and retired at the end of the Employment Period (at which time he will be treated as eligible for all retiree welfare benefits and other benefits provided to retired senior executives, as set forth in Section 3(c)(ii) and (iii)); PROVIDED, that the annual bonus for such period shall be based upon the Target Bonus; PRO- -7- VIDED, further that, to the extent any benefits described in paragraph (c) of Section 3 cannot be provided pursuant to the plan or program maintained by the Company for its executives, the Company shall provide such benefits outside such plan or program at no additional cost (including without limitation tax cost) to the Executive and his family, and PROVIDED, further, that during any period when the Executive is eligible to receive benefits of the type described in clause (B) of Section 3(c)(iii) under another employer-provided plan, the benefits provided by the Company under Section 5(a) may be made secondary to those provided under another plan. In addition to the foregoing, any restricted stock outstanding on the Date of Termination shall be fully vested as of the Date of Termination and all options outstanding on the Date of Termination shall be fully vested and exercisable and shall remain in effect and exercisable through the end of their respective terms, without regard to the termination of the Executive's employment. The payments and benefits provided pursuant to this Section 5(a) are intended as liquidated damages for a termination for the Executive's employment by the Company other than for Cause or Disability or for the actions of the Company leading to a termination of the Executive's employment by the Executive for Good Reason, and shall be the sole and exclusive remedy therefor. (b) DEATH OR DISABILITY. If the Executive's employment is terminated by reason of the Executive's death or Disability during the Employment Period, the Company shall pay to the Executive, or in the cause of the Executive's death, to the Executive's designated beneficiaries (or, if there is no such beneficiary, to the Executive's estate or legal representative) in a lump sum in cash within 30 days after the Date of Termination, the sum of the following amounts (the "Accrued Obligations"): (1) any portion of the Executive's Annual Base Salary through the Date of Termination that has not yet been paid; (2) an amount equal to the Target Bonus times a fraction, the numerator of which is the number of days in such period through the Date of Termination, and the denominator of which is 365; and (3) any accrued but unpaid incentive compensation and vacation pay; and the Company shall have no further obligations under this Agreement, except as specified in Section 3(c)(i) and (e) above and Section 6 and Section 9 below. If the Executive's employment is terminated by reason of Disability, he shall be entitled to receive the maximum disability payments which can be provided under the disability plans described in Section 3(c)(iii), reduced, however, by actual disability benefits received under such plans. (c) BY THE COMPANY FOR CAUSE; BY THE EXECUTIVE OTHER THAN FOR GOOD REASON. If the Executive's employment is terminated by the Company for Cause during the Employment Period, the Company shall pay the Executive the Annual Base Salary through the Date of Termination and the amount of any compensation previously deferred by the Executive (together with any accrued interest or earnings thereon), in each case to the extent not yet paid, and the Company shall have no further obligations under this Agreement, except as specified in Section 3(c)(i) above and Section 6 and Section 9 below. If the Executive voluntarily terminates employment during the Employment Period, other than for Good Reason, the Company shall pay the Accrued Obligations to the Executive in a lump sum in cash within 30 days of the Date of Termination, and the Company shall have no further obligations under this Agreement, except as specified in Section 3(c)(i) above and Section 6 and Section 9 below. -8- 6. NON-EXCLUSIVITY OF RIGHTS. Nothing in this Agreement shall prevent or limit the Executive's continuing or future participation in any plan, program, policy or practice provided by the Company or any of its affiliated companies for which the Executive may qualify, nor, subject to paragraph (f) of Section 12, shall anything in this Agreement limit or otherwise affect such rights as the Executive may have under any contract or agreement with the Company or any of its affiliated companies. Vested benefits and other amounts that the Executive is otherwise entitled to receive under any plan, policy, practice or program of, or any contract or agreement with, the Company or any of its affiliated companies on or after the Date of Termination shall be payable in accordance with the terms of each such plan, policy, practice, program, contract or agreement, as the case may be, except as explicitly modified by this Agreement. 7. FULL SETTLEMENT. The Company's obligation to make the payments provided for in, and otherwise to perform its obligations under this Agreement shall not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action that the Company may have against the Executive or others. In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement and, except as specifically provided in Section 5(a) with respect to benefits described in clause (B) of Section 3(c)(iii), such amounts shall not be reduced, regardless of whether the Executive obtains other employment. 8. NON-COMPETITION PROVISION AND CONFIDENTIAL INFORMATION. In consideration for $2,500,000 of the Special Retention Bonus provided for in Section 3(e) above, the Executive agrees to the following covenants. (a) Without prior written consent of the Company, for the greater of (i) the twenty-four (24) month period following the Date of Termination, or (ii) the remaining term of this Agreement, the Executive shall not, as a shareholder, officer, director, partner, consultant, or otherwise, engage directly or indirectly in any business or enterprise which is "in competition" with the Company or its successors or assigns; provided, however, that the Executive's ownership of less than five percent of the issued and outstanding voting securities of a publicly-traded company shall not be deemed to constitute such competition. A business or enterprise is deemed to be "in competition" if it is engaged in the business of generation, purchase, transmission, distribution, or sale of electricity, or in the purchase, transmission, distribution, sale or transportation of natural gas within the States of Colorado, Kansas, Minnesota, New Mexico, Oklahoma, North Dakota, South Dakota, Texas, Wisconsin or Wyoming. (b) The Executive shall hold in a fiduciary capacity for the benefit of the Company all secret or confidential information, knowledge or data relating to the Company or any of its affiliated companies and their respective businesses that the Executive obtains during the Executive's employment by the Company or any of its affiliated companies and that is not public knowledge (other than as a result of the Executive's violation of this Section 8) ("Confidential Information"). The Executive shall not communicate, divulge or disseminate Confidential Information at any time during or after the Executive's employment with the Company, except with the prior written consent of the Company or as otherwise required by -9- law or legal process. In no event shall any asserted violation of the provisions of this Section 8 constitute a basis for deferring or withholding any amounts otherwise payable to the Executive under this Agreement. 9. CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY. (a) Anything in this Agreement to the contrary notwithstanding, in the event it shall be determined that any payment or distribution by the Company to or for the benefit of the Executive (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, but determined with regard to any additional payments required under this Section 9) (a "Payment") would be subject to the excise tax imposed by Section 4999 of the Code, or any interest or penalties are incurred by the Executive with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the "Excise Tax"), then the Executive shall be entitled to receive an additional payment (a "Gross-Up Payment") in an amount such that after payment by the Executive of all taxes (including any interest or penalties imposed with respect to such taxes) including, without limitation, any income taxes (and any interest and penalties imposed with respect thereto) and Excise Tax imposed upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments. (b) Subject to the provisions of paragraph (c) of this Section 9, all determinations required to be made under this Section 9, including whether and when a Gross-Up Payment is required and the amount of such Gross-Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by a nationally recognized certified public accounting firm designated by the Executive (the "Accounting Firm"), which shall provide detailed supporting calculations both to the Company and the Executive within 15 business days of the receipt of notice from the Executive that there has been a Payment, or such earlier time as is requested by the Company. All fees and expenses of the Accounting Firm shall be borne solely by the Company. Any Gross-Up Payment, as determined pursuant to this Section 9, shall be paid by the Company to the Executive within five days of the receipt of the Accounting Firm's determination. Any determination by the Accounting Firm shall be binding upon the Company and the Executive. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments which will not have been made by the Company should have been made ("Underpayment") consistent with the calculations required to be made hereunder. In the event that the Company exhausts its remedies pursuant to paragraph (c) of this Section 9 and the Executive thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by the Company to or for the benefit of the Executive. (c) The Executive shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Company of the Gross-Up Payment. Such notification shall be given as soon as practicable but not later than ten business days after the Executive is informed in writing of such claim and shall apprise the -10- Company of the nature of such claim and the date on which such claim is requested to be paid. The Executive shall not pay such claim prior to the expiration of the 30-day period following the date on which it gives such notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies the Executive in writing prior to the expiration of such period that it desires to contest such claim, the Executive shall: (i) give the Company any information reasonably requested by the Company relating to such claim; (ii) take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company; (iii) cooperate with the Company in good faith in order effectively to contest such claim; and (iv) permit the Company to participate in any proceedings relating to such claim; PROVIDED, however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold the Executive harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties with respect thereto) imposed as a result of such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this paragraph (c) of Section 9, the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct the Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and the Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine, PROVIDED, however, that if the Company directs the Executive to pay such claim and sue for a refund, the Company shall advance the amount of such payment to the Executive, on an interest-free basis and shall indemnify and hold the Executive harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or penalties with respect thereto) imposed with respect to such advance or with respect to any imputed income with respect to such advance; and PROVIDED, further, that any extension of the statute of limitations relating to payment of taxes for the taxable year of the Executive with respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore, the Company's control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder and the Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority. -11- (d) If, after the receipt by the Executive of an amount advanced by the Company pursuant to paragraph (c) of this Section 9, the Executive becomes entitled to receive any refund with respect to such claim, the Executive shall (subject to the Company's complying with the requirements of paragraph (c) of this Section 9) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If after the receipt by the Executive of an amount advanced by the Company pursuant to paragraph (c) of this Section 9, a determination is made that the Executive shall not be entitled to any refund with respect to such claim and the Company does not notify the Executive in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid. 10. ATTORNEY'S FEES. The Company agrees to pay, as incurred, to the fullest extent permitted by law, all legal fees and expenses that the Executive may reasonably incur as a result of any contest regardless of the outcome by the Company, the Executive or others of the validity or enforceability of or liability under or otherwise involving, any provision of this Agreement, together with interest on any delayed payment at the applicable federal rate provided for in Section 7872(f)(2)(A) of the Code. 11. SUCCESSORS. (a) This Agreement is personal to the Executive and, without the prior written consent of the Company, shall not be assignable by the Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive's legal representatives. (b) This Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns. (c) The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would have been required to perform it if no such succession had taken place. As used in this Agreement, "Company" shall mean both the Company as defined above and any such successor that assumes and agrees to perform this Agreement, by operation of law or otherwise. 12. MISCELLANEOUS. (a) This Agreement shall be governed by, and construed in accordance with, the laws of the State of Minnesota, without reference to principles of conflict of laws. The captions of this Agreement are not part of the provisions hereof and shall have no force and effect. This Agreement may not be amended or modified except by a written agreement executed by the parties hereto or their respective successors and legal representatives. -12- (b) All notices and other communications under this Agreement shall be in writing and shall be given by hand delivery to the other party or by registered or certified mail, return receipt requested, postage prepaid, addressed as follows: If to the Executive: James J. Howard If to the Company: Northern States Power Company 414 Nicollet Mall Minneapolis, Minnesota 55401 Attention: General Counsel or to such other address as either party furnishes to the other in writing in accordance with this paragraph (b) of Section 12. Notices and communications shall be effective when actually received by the addressee. (c) The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement. If any provision of this Agreement shall be held invalid or unenforceable in part, the remaining portion of such provision, together with all other provisions of this Agreement, shall remain valid and enforceable and continue in full force and effect to the fullest extent consistent with law. (d) Notwithstanding any other provision of this Agreement, the Company may withhold from amounts payable under this Agreement all federal, state, local and foreign taxes that are required to be withheld by applicable laws or regulations.
