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.

valid and enforceable and continue in full force and effect to the fullest

compliance with any provision of, or to assert any right under, this 
Agreement (including, without limitation, the right of the Executive to

right or of any other provision of or right under this Agreement.

may not be anticipated, assigned, alienated or subject to attachment, 
garnishment, levy, execution or other legal or equitable process except as 
required by law. Any attempt by the Executive to anticipate, alienate, 
assign, sell, transfer, pledge, encumber or charge the same shall be void.  
Payments hereunder shall not be considered assets of the Executive in the 
event of insolvency or bankruptcy.
