   Merger, as amended (the "Merger Agreement"), dated November 10, 1995, by
   and among the Company, IES Industries Inc., an Iowa corporation ("IES"),
   Interstate Power Company, a Delaware corporation ("Interstate Power"),
   WPLH Acquisition Co., a Wisconsin corporation and a wholly-owned
   subsidiary of the Company, and Interstate Power Company, a Wisconsin
   corporation and a wholly-owned subsidiary of Interstate; and

             WHEREAS, the parties to the Merger Agreement wish to provide for
   the orderly succession of management of the Company following the
   Effective Time (as defined in the Merger Agreement); and

             WHEREAS, the parties to the Merger Agreement further wish to
   provide for the employment by the Company of the Executive, and the
   Executive wishes to serve the Company and its subsidiaries, in the
   capacities and on the terms and conditions set forth in this Agreement.

             NOW, THEREFORE, it is hereby agreed as follows:

             1.   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, for an initial period (the "Initial Period")
   commencing at the Effective Time and ending on the date immediately
   preceding the fifth anniversary of the Effective Time.  This Agreement
   thereafter will automatically renew for successive terms of one (1) year
   each, unless either party hereto has given sixty (60) days' advance
   written notice of its or his intent to allow the term of this Agreement to
   expire.  The term during which the Executive is employed by the Company
   hereunder (including without limitation the Initial Period) is hereafter
   referred to as the "Employment Period."  Upon the termination of the
   Employment Period the Executive will have the status of a retired senior
   executive officer of the Company and shall be entitled to all of the
   rights, privileges and benefits provided to such retired officers.

             2.   Position and Duties.

                  (a)  During the first two (2) years of the Initial Period,
             the Executive shall serve as President and Chief Executive
             Officer of the Company and thereafter, until the end of the
             Employment Period, the Executive shall serve as Chairman of the
             Board of Directors, President and Chief Executive Officer of the
             Company; in each case with 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 of Directors
             of the Company (the "Board").  The Executive also shall continue
             to serve as a member of the Board following the Effective Time,
             and the Board shall propose the Executive for re-election to the
             Board throughout the Employment Period.

                  (b)  In addition to the responsibilities designated in
             paragraph (a) of Section 2 above, during the three-year period
             following the Effective Time, the Executive shall be entitled to
             serve as the Chief Executive Officer of each entity which during
             such period is a subsidiary of the Company and the Company shall
             cause the Executive to be appointed or elected as the Chief
             Executive Officer of each such subsidiary.  In his capacity as
             the Chief Executive Officer of said subsidiaries, the Executive
             shall have such duties and responsibilities as are customarily
             assigned to such position, and such other duties and
             responsibilities not inconsistent therewith as may from time to
             time be assigned to him by the Board of Directors of each such
             subsidiary.  During the Employment Period, the Executive also
             shall serve as a member of the Board of Directors of each of the
             Company's subsidiaries and the Company shall cause the Executive
             to be appointed, elected or re-elected as such a director.

                  (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 its affiliates 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 corporate, 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 and its
             affiliates in accordance with this Agreement.

                  (d)  The Company's headquarters shall be located in
             Madison, Wisconsin and the Executive shall reside in the general
             area of Madison, Wisconsin.  During the Employment Period, the
             Company also will provide the Executive with a furnished
             apartment in the Cedar Rapids, Iowa area.

             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 and Personnel Committee (or
             other appropriate committee) of the Board, subject to the next
             sentence and paragraph (b) of Section 3.  During the Employment
             Period, the Executive shall receive an annual base salary
             ("Annual Base Salary") of not less than his aggregate annual
             base salary from the Company and its subsidiaries as in effect
             immediately before the Effective Time.  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.  During the Employment Period, the Annual Base
             Salary shall be reviewed for possible increase at least
             annually.  Any increase in the Annual Base Salary shall not
             limit or reduce any other obligation of the Company under this
             Agreement.  The Annual Base Salary shall not be reduced after
             any such increase, and the term "Annual Base Salary" shall
             thereafter refer to the Annual Base Salary as so increased.

                  (b)  Incentive Compensation.  During the Employment Period,
             the Executive shall continue to participate in short-term
             incentive compensation plans and long-term incentive
             compensation plans (the latter to consist of plans offering
             stock options, restricted stock and other long-term incentive
             compensation) offered by the Company and its present or future
             affiliates which shall provide him with the opportunity to earn,
             on a year-by-year basis, short-term and long-term incentive
             compensation (the "Incentive Compensation") at least equal to
             the amounts that he had the opportunity to earn immediately
             before the Effective Time, and such compensation shall be
             payable in accordance with standards (i.e., performance
             criteria, performance levels, etc.) which are no less favorable
             to the Executive than those applicable with respect to the
             Incentive Compensation payable to the Executive immediately
             before the Effective Time.

                  (c)  Other Benefits.

                       (i)  Retirement Plan; Supplemental Retirement Plan. 
                  During the Employment Period, the Executive shall
                  participate in a retirement plan and/or supplemental
                  retirement plan (the "Defined Benefit Arrangement") such
                  that the aggregate value of the retirement benefits that he
                  and his spouse will receive at the end of the Employment
                  Period under all defined benefit plans of the Company and
                  its affiliates (whether qualified or not) will be not less
                  than the benefits he would have received (assuming his
                  employment through the end of the Employment Period) under
                  the Wisconsin Power and Light Company Retirement Plan and
                  the Supplemental Retirement Plan in which the Executive
                  participates, as in effect immediately prior to the
                  Effective Time.

                       (ii) Executive Tenure Compensation Plan.  During the
                  Employment Period, the Executive shall continue to
                  participate in the Wisconsin Power and Light Company
                  Executive Tenure Compensation Plan.

                       (iii)     Life Insurance.  During the Employment
                  Period, the Company shall provide the Executive with life
                  insurance coverage (the "Life Insurance Coverage")
                  providing a death benefit to such beneficiary or
                  beneficiaries as the Executive may designate of not less
                  than three times his Annual Base Salary.

                       (iv) Additional Benefits.  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 affiliates to the same
                  extent as other senior executives (or, where applicable,
                  retired senior executives) of the Company, and (B) the
                  Executive and/or the Executive's family, as the case may
                  be, shall be eligible for immediate participation in (and
                  without any limitation for preexisting conditions), and
                  shall receive all benefits under, all applicable welfare
                  benefit plans, practices, policies and programs provided by
                  the Company and its affiliates, other than severance plans,
                  practices, policies and programs but including, without
                  limitation, medical, prescription, dental, disability,
                  salary continuance, employee life insurance, group life
                  insurance, accidental death and travel accident insurance
                  plans and programs, to the same extent as other senior
                  executives (or, where applicable, retired senior
                  executives) of the Company, provided, however, that the
                  Executive's aggregate benefits as a retired senior
                  executive under the plans described in this clause (B)
                  shall not be less than the benefits provided by the Company
                  and its affiliates to its retired senior executive officers
                  as of the date of this Agreement.

                  (d)  Perquisites.  During the Employment Period, the
             Executive shall be entitled to receive such perquisites as the
             Company may establish from time to time which are commensurate
             with his position and at lease comparable to those received by
             other senior executives at the Company.

                  (e)  Expense Reimbursement.  The Company shall reimburse
             the Executive for all reasonable and documented expenses
             incurred by the Executive in the performance of the Executive's
             duties under this Agreement.

             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 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
                       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 (10) and not
                  more than twenty (20) business days after the Executive
                  receives the Notice of Termination for Cause.  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 a two-thirds vote of the
                  entire membership of the Board, excluding employee
                  directors, 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.

                       (iii)     A termination of the Executive's employment
                  without Cause shall be effected 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 (10) and not more than twenty (20) 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 a two-thirds vote of the entire membership
                  of the Board, excluding employee directors, 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 paragraphs (a)
                       and (b) 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.   any requirement by the Company that the
                       Executive's services be rendered primarily at a
                       location or locations other than that provided for in
                       paragraph (d) of Section 2 of this Agreement;

                            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

                            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.

                       (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 within six months of the event constituting
                  Good Reason, 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 thirty (30) days after the notice is given).

                       (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)  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, Death or
             Disability; by the Executive for Good Reason.  If, during the
             Employment Period, the Company terminates the Executive's
             employment, other than for Cause, Death, 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) and (c) of Section
             3 as if he had remained employed by the Company pursuant to this
             Agreement through the end of the Employment Period and then
             retired (at which time he will be treated as eligible for and
             will be entitled to receive all retiree welfare benefits and
             other benefits provided to retired senior executives, as set
             forth in Section 3(c), with such benefits being calculated for
             this purpose as though the Executive had retired at age 62 with
             earnings on an annual basis during the years between the Date of
             Termination and age 62 equal to the Executive's earnings for the
             year immediately preceding the Date of Termination); provided,
             that the Incentive Compensation for the period through the end
             of the Employment Period shall be equal to the maximum Incentive
             Compensation that the Executive would have been eligible to earn
             for such period; provided, further that in lieu of stock
             options, restricted stock and other stock-based awards, the
             Executive shall be paid cash equal to the fair market value
             (without regard to any restrictions) of the stock options,
             restricted stock and other stock-based awards that would
             otherwise have been granted; and provided, 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, finally, that during any period when the
             Executive is eligible to receive benefits of the type described
             in clause (B) of paragraph (c)(iv) of Section 3 under another
             employer-provided plan, the benefits provided by the Company
             under this paragraph (a) of Section 5 may be made secondary to
             those provided under such other 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 paragraph (a) of
             Section 5 are intended as liquidated damages for a termination
             of 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 and 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 case 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 thirty (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 representing the Incentive Compensation for
             the period that includes the Date of Termination, computed by
             assuming that the amount of all such Incentive Compensation
             would be equal to the maximum amount of such Incentive
             Compensation that the Executive would have been eligible to earn
             for such period, and multiplying that amount by 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 the
             total number of days in the relevant period; (3) any
             compensation previously deferred by the Executive (together with
             any accrued interest or earnings thereon) that has not yet been
             paid; and (4) any accrued but unpaid Incentive Compensation and
             vacation pay.  Any deferred compensation (together with any
             accrued interest or earnings thereon, if any) that has not yet
             been paid, will be paid in accordance with the terms and
             conditions applicable to such deferred compensation.

                  (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 6 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 thirty (30) days of the Date of Termination, and the
             Company shall have no further obligations under this Agreement,
             except as specified in Section 6 below.

             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
   affiliates for which the Executive may qualify, nor 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 affiliates
   relating to subject matter other than that specifically addressed herein. 
   Vested benefits and other amounts that the Executive is otherwise entitled
   to receive under the Incentive Compensation program, the Defined Benefit
   Arrangement, the Life Insurance Coverage, the Executive Tenure
   Compensation Plan, the Executive's Deferred Compensation Plan(s), or any
   other plan, policy, practice or program of, or any contract or agreement
   with, the Company or any of its affiliates 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.  The amounts payable by the Company under
   this Agreement shall not be offset or reduced by any amounts otherwise
   receivable or received by the Executive from any source, except as
   specifically provided in paragraph (a) of Section 5 with respect to
   benefits described in clause (B) of paragraph (c)(iv) of Section 3.

             8.   Confidential Information.  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 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.   Limitation on Payments.  

                  (a)  Notwithstanding any other provision of this Agreement,
             if any portion of any payment under this Agreement, or under any
             other agreement with or plan of the Company or its affiliates
             (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 (or any successor provision) of the
             Internal Revenue Code of 1986, as amended (the "Code") or which
             the Company may pay without loss of deduction under 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 fifteen (15) days following the
             Date of 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 selected by the Company's independent
             auditors and acceptable to the Executive in his sole discretion
             (which may be regular outside counsel to the Company), which
             opinion sets forth (i) the amount of the Base Period Income,
             (ii) the amount and present value of Total Payments and (iii)
             the amount and present value of any excess parachute payments
             determined without regard to the limitations of this paragraph
             (a) of Section 9.  As used in this Agreement, the term "Base
             Period Income" means an amount equal to the Executive's
             "annualized includible compensation for the base period" as
             defined in Section 280G(d)(1) of the Code (or any successor
             provision).  For purposes of such opinion, the value of any
             noncash benefits or any deferred payment or benefit shall be
             determined 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.  Such opinion shall be dated as of
             the Date of Termination and addressed to the Company and the
             Executive and shall be binding upon the Company and the
             Executive.  If such opinion determines that there would be an
             excess parachute payment, any payment or benefit determined by
             such counsel to be includible in Total Payments shall be reduced
             or eliminated as specified by the Executive in writing delivered
             to the Company within thirty (30) 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 legal counsel so
             requests in connection with the opinion required by this
             paragraph (a) of Section 9, the Executive and the Company shall
             obtain, at the Company's expense, and the legal counsel may rely
             on in providing the opinion, 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.  If
             the provisions of Sections 280G and 4999 of the Code (or any
             successor provisions) are repealed without succession, then this
             paragraph (a) of Section 9 shall be of no further force or
             effect.

                  (b)  If, notwithstanding the provisions of paragraph (a) of
             Section 9, it is ultimately determined by a court or pursuant to
             a 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
             paragraph (b) of Section 9, 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.

             10.  Attorneys' 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.  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 Wisconsin, without
             reference to principles of conflict of laws.  The captions of
             this Agreement are not part of the provisions hereof and shall

             hereto or their respective successors and legal representatives.

             this Agreement shall be held invalid or unenforceable in part,

                  (d)  Notwithstanding any other provisions 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.

                  (e)  The Executive's or the Company's failure to insist
             upon strict compliance with any provisions of, or to assert any
             right under, this Agreement (including, without limitation, the
             right of Executive to terminate employment for Good Reason
             pursuant to paragraph (c) of Section 4 of this Agreement) shall
             not be deemed to be a waiver of such provision or right or of
             any other provision of or right under this Agreement.

                  (f)  The Executive and the Company acknowledge that this
             Agreement supersedes any other agreement between them concerning
             the subject matter hereof, excluding the agreement between the
             Executive and the Company dated June 25, 1994, as in effect on
             the date hereof or as hereafter amended from time to time (the
             "Severance Agreement"); provided, however, that to the extent
             that a payment or benefit to be provided under this Agreement is
             similarly to be provided under the Severance Agreement, the
             Company agrees to pay or provide to the Executive that payment
             or benefit which provides the highest value to the Executive,
             and the Executive agrees, in order to avoid duplication of
             payments or benefits, that upon the receipt of any such highest
             value payment or benefit under either this Agreement or the
             Severance Agreement, as the case may be, he shall have no right
             to any similar payment or benefit of lesser value under the
             other agreement.

                  (g)  The rights and benefits of the Executive 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.

                  (h)  This Agreement may be executed in several
             counterparts, each of which shall be deemed an original, and
             said counterparts shall constitute but one and the same
             instrument.

             13.  Effectiveness of Agreement.  The effectiveness of this
   Agreement is subject to the consummation of the Merger (as defined in the
   Merger Agreement).  If for any reason the Merger is not consummated in
   accordance with the terms of the Merger Agreement, this Agreement shall be
   null and void, ab initio.

                  IN WITNESS WHEREOF, the Executive has hereunto set the
   Executive's hand and, pursuant to the authorization of its Board of
   Directors, the Company has caused this Agreement to be executed in its
   name and on its behalf, all as of the day and year first above written.
