          THIS AGREEMENT by and between Interstate Energy Corporation, a
   Wisconsin corporation (the "Company"), and Lee Liu (the "Executive"),
   dated as of the 21st day of April, 1998.

          WHEREAS, WPL Holdings, Inc., IES Industries Inc. ("IES
   Industries"), Interstate Power Company, a Delaware corporation, WPLH
   Acquisition Co. and Interstate Power Company, a Wisconsin corporation
   (collectively, the "Merger Parties"), have entered into an Agreement and
   Plan of Merger dated as of November 10, 1995, as amended (the "Merger
   Agreement"); and

          WHEREAS, the Merger Parties 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 Merger Parties 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.   Employment Period.  The Company shall employ the Executive,
   and the Executive shall serve the Company as an employee and officer of
   the Company, on the terms and conditions set forth in this Agreement, for
   the period commencing on the Effective Time and ending on the date
   immediately preceding the second anniversary of the Effective Time (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)  Title.  During the Employment Period, the Executive shall
   serve as Chairman of the Board of Directors (the "Board") of the Company
   ("Chairman").  Upon termination of the Employment Period, the Executive
   shall continue to be eligible to serve as a director of the Company.

          (b)  Duties.  During the Employment Period, the Executive shall
   perform the normal and ordinary duties of Chairman and shall serve,
   together with the Vice Chairman of the Board and the Chief Executive
   Officer, as a member of the senior executive team of the Company charged
   with responsibility for developing and implementing programs to achieve
   the corporate integration and restructuring of the Merger Parties
   following the Effective Time.  In addition, he will have involvement, as
   appropriate, in government regulatory initiatives, will be involved in
   major economic development initiatives of the Company and will serve in
   such other capacities and will perform such other functions consistent
   with his status as Chairman as may be reasonably assigned by the Board
   from time to time.  The Executive shall devote the necessary time and
   effort required to perform the above described duties.  

          (c)  Office.  The Executive's services hereunder shall be performed
   primarily at the existing executive offices of IES Industries located in
   Cedar Rapids, Iowa, subject to such business travel as shall be necessary
   and appropriate.  

          3.   Compensation.  

          (a)  Base Salary.  During the Employment Period, the Executive
   shall receive an annual base salary ("Annual Base Salary") of not less
   than Four Hundred Thousand Dollars ($400,000), 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 participate in such short-term incentive compensation
   plans and long-term incentive compensation plans as shall be decided upon
   in the discretion of the Compensation Committee of the Board (the
   "Compensation Committee") (the latter to consist of plans offering stock
   options, restricted stock and/or other long-term incentive compensation),
   providing him with the opportunity to earn, on an annualized basis, short-
   term and long-term incentive compensation (collectively, the "Incentive
   Compensation") not less than the aggregate amount of the incentive
   compensation that the Executive had an opportunity to earn under IES
   Industries' Management Incentive Compensation Plan (the "MICP") and Long-
   Term Incentive Plan (the "LTIP") in respect of the calendar year ended
   immediately prior to the Effective Time, and such Incentive 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 amounts that were payable to the
   Executive under each of the MICP and the LTIP in respect of the calendar
   year ended immediately prior to the Effective Time.

          (c)  Other 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, (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 pre-existing conditions), and shall receive all benefits
   under, all applicable welfare benefit plans, practices, policies and
   programs provided by the Company and its affiliates, including, without
   limitation, medical, prescription, dental, disability, salary continuance,
   accidental death and travel 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 IES
   Industries to its retired senior executive officers as of the date of this
   Agreement and (C) the Company shall maintain, at no cost to the Executive,
   life insurance on the life of the Executive payable to one or more
   beneficiaries designated by the Executive in an amount not less than the
   aggregate amount of the life insurance provided to the Executive by IES
   Industries immediately prior to the Effective Time.

          (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 least
   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.

          (f)  Supplemental Retirement Benefit.  The Executive and IES
   Industries have entered into that certain Amended and Restated
   Supplemental Retirement Agreement dated February 1, 1993, as amended (the
   "Supplemental Retirement Agreement").  The Company shall assume, honor and
   perform the obligations of IES Industries under the Supplemental
   Retirement Agreement (as amended as set forth below).  In addition, the
   Company and the Executive agree that as of the Effective Time the terms of
   the Supplemental Retirement Agreement shall be amended as provided below. 
   (Capitalized terms used below in this Section 3(f) which are not otherwise
   specifically defined in this Agreement shall have the meanings ascribed to
   such terms in the Supplemental Retirement Agreement as amended hereby). 
   The Supplemental Retirement Agreement shall be amended as follows:

               (i)  the term "Annual Salary" as defined in Section 2.1 of the
                    Supplemental Retirement Agreement for purposes of
                    calculating the benefit payable to the Executive and his
                    Designated Beneficiary under the Supplemental Retirement
                    Agreement shall be modified so that "Annual Salary" shall
                    be the sum of (A) the Executive's Annual Base Salary and
                    (B) an amount equal to the average of the annual
                    incentive awards payable to the Executive under the IES
                    Industries MICP in respect of each of the three (3)
                    consecutive annual performance periods ended immediately
                    prior to the Effective Time of the Merger;

               (ii) the Executive shall be fully vested in and entitled to
                    receive, at Normal Retirement Age, the full amount of his
                    Normal Retirement Benefit under the Supplemental
                    Retirement Agreement, as amended hereby, and the
                    Executive shall be deemed to have attained Normal
                    Retirement Age for all purposes under the Supplemental
                    Retirement Agreement as of the date on which he ceases,
                    for any reason, to receive the compensation and benefits
                    set forth in paragraphs (a), (b) and (c) of Section 3 of
                    this Agreement; 

              (iii) Sections 3.2, 3.3 and 4.1 of the Supplemental
                    Retirement Agreement shall be amended to provide that
                    in the event of the Executive's death at any time on
                    or after the Effective Time, the Executive's
                    Designated Beneficiary shall receive monthly
                    Supplemental Benefit payments or Death Benefit
                    payments, as the case may be, for a period of months
                    that, when added to the number of months, if any,
                    during which the Executive received monthly benefits
                    under the Supplemental Retirement Agreement, will be
                    equal to one hundred eighty (180) months; and

               (iv) for purposes of Section 9.1 of the Supplemental
                    Retirement Agreement, in the event of the Executive's
                    death, the Executive shall be treated as receiving the
                    Supplemental Benefit portion of the Normal Retirement
                    Benefit at the time of death regardless of whether he was
                    actually receiving such Supplemental Benefit at such
                    time.  

          The foregoing modifications to the terms of the Supplemental
   Retirement Agreement shall take effect as of the Effective Time.  As soon
   as practicable following the Effective Time (but in no event later than 60
   days after the Effective Time), the Company and the Executive shall take
   all actions necessary to execute a formal amendment to the Supplemental
   Retirement Agreement incorporating the modifications set forth above. 
   Until the time that such a formal amendment is properly executed, the
   provisions of this Section 3(f) shall serve and be construed, for all
   intents and purposes, as an amendment to the terms of the Supplemental
   Retirement Agreement, and the obligations of the Company thereunder shall
   be governed by the terms of the Supplemental Retirement Agreement as so
   amended.

          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 one hundred and eighty (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 thirtieth (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 of Directors of the Company (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 Board Meeting for Cause.  The "Board Meeting for
   Cause" means a meeting of the Board at which the Executive's termination
   for Cause will be considered, 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 Board Meeting for
   Cause.  The Executive's termination for Cause shall be effective when and
   if a resolution is duly adopted at the 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 Board Meeting
   without Cause.  The "Board Meeting without Cause" means a meeting of the
   Board at which the Executive's termination without Cause will be
   considered, 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 Board Meeting without Cause. 
   The Executive's termination without Cause shall be effective when and if a
   resolution is duly adopted at the 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 (c) 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 12 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 (6) 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 (5th) 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 all retiree welfare benefits and other benefits
   provided to retired senior executives, as set forth in Sections 3(c) and
   (f)); PROVIDED, that the Incentive Compensation for such 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; PROVIDED,
   further, that to the extent any benefits described in paragraph (c) of
   Section 3 cannot be provided pursuant to a 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) 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 surviving spouse, or
   if the Executive is not survived by a spouse, 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 been earned but 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 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, the deferred compensation and other benefit
   programs listed in paragraph (c) of Section 3, 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) 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
   secret or confidential information, knowledge or data which becomes public
   knowledge 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.  Executive's Service on the Board.

          (a)  Appointment and Nomination.  The Company shall appoint the
   Executive as a member of the Board for an initial three (3) year term
   commencing on the Effective Date (the "Initial Board Term").  

          (b)  Board and Committee Compensation.  The Executive shall be
   compensated for his Board services in accordance with the general policies
   and practices of the Company as in effect from time to time relating to
   the compensation of employee and non-employee directors, as the case may
   be, and to the extent that such policies and practices provide for such
   compensation.

          (c)  Office and Secretarial Assistance.  Provided that the
   Executive remains in the employ of the Company as of the conclusion of the
   Employment Period and continues to serve as a member of the Board
   throughout his initial three-year term as a director, the Company shall
   provide to the Executive, for a period of one (1) year following the
   conclusion of the Employment Period, a furnished office and a full-time
   secretary at the Executive's disposal at the existing executive offices of
   IES Industries in Cedar Rapids, Iowa for the Executive's use in connection
   with any continuing business of the Company and any personal business of
   the Executive.

          11.  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.

          12.  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.

          13.  Miscellaneous.  (a)  This Agreement shall be governed by, and
   construed in accordance with, the laws of the State of Iowa, 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 or
   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.

          (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 facsimile, addressed as follows:

          (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.

          (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 the 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 the Employment Agreement between IES Industries and the

          (g)  The rights and benefits of the Executive under this Agreement
   may not be anticipated, 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.

          14.  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 the Board of Directors, the
   Company has caused this Agreement to be executed in its name on its
   behalf, all as of the day and year first above written.
