The nominees for election as selected by the Nominating and Governance Committee of the Company's Board of Directors are: Erroll B. Davis, Jr., Lee Liu, Milton E. Neshek, Robert W. Schlutz and Wayne H. Stoppelmoor. Each of the nominees is currently serving as a director of the Company. Each person elected as director will serve until the Annual Meeting of Shareowners of the Company in 2003 or until his successor has been duly elected and qualified. Directors will be elected by a plurality of the votes cast at the meeting (assuming a quorum is present). Consequently, any shares not voted at the meeting will have no effect on the election of directors. The proxies solicited may be voted for a substitute nominee or nominees in the event that any of the nominees shall be unable to serve, or for good reason will not serve, a contingency not now anticipated. Brief biographies of the director nominees and continuing directors follow. These biographies include their age (as of December 31, 1999), an account of their business experience and the names of publicly-held and certain other corporations of which they are also directors.

However, the Board has established standing Audit, Compensation and Personnel, and Nominating and Governance Committees, each of which is chaired by an outside director, so that certain important matters can be addressed in more depth than may be possible in a full Board meeting. The following is a description of each of these committees: Audit Committee The Audit Committee held two meetings in 1999. This Committee currently consists of J. L. Hanes (Chair), J. B. Evans, K. C. Lyall, M. E. Neshek and R. W. Schlutz. The Audit Committee recommends to the Board the appointment of independent auditors; reviews the reports and comments of the independent auditors; reviews the activities and reports of the Company's internal audit staff; and, in response to the reports and comments of both the independent auditors and internal auditors, recommends to the Board any action which the Committee considers appropriate. Compensation and Personnel Committee The Compensation and Personnel Committee held three meetings in 1999. This Committee currently consists of A. M. Nemirow (Chair), A. B. Arends, J. D. Pyle and A. R. Weiler. This Committee sets executive compensation policy; administers the Company's Long-Term Equity Incentive Plan; reviews the performance of and approves salaries for officers and certain other management personnel; reviews and recommends to the Board new or changed employee benefit plans; reviews major provisions of negotiated employment contracts; and reviews human resource development programs. Nominating and Governance Committee The Nominating and Governance Committee held three meetings in 1999. The Nominating and Governance Committee currently consists of R. G. Flowers (Chair), A. B. Arends, J. D. Pyle, R. D. Ray and A. R. Weiler. This Committee's responsibilities include recommending and nominating new members of the Board; recommending committee assignments and committee chairpersons; evaluating overall Board effectiveness; preparing an annual report on Chief Executive Officer effectiveness; and considering and developing recommendations to the Board of Directors on other corporate governance issues. In making recommendations of nominees for election to the Board, the Nominating and Governance Committee will consider nominees recommended by shareowners. Any shareowner wishing to make a recommendation should write to the Corporate Secretary of the Company, who will forward all recommendations to the Committee. The Company's Bylaws also provide for shareowner nominations of candidates for election as directors. These provisions require such nominations to be made pursuant to timely notice (as specified in the Bylaws) in writing to the Corporate Secretary of the Company. The Board of Directors held six meetings during 1999. All directors attended at least 78% of the aggregate number of meetings of the Board and Board committees on which he or she served. The Board and each committee conducts performance evaluations annually to determine its effectiveness and suggests improvements for consideration and implementation. In addition, Mr. Davis' performance as Chief Executive Officer is also evaluated by the full Board on an annual basis. -12- COMPENSATION OF DIRECTORS No retainer fees are paid to Messrs. Davis, Liu and Stoppelmoor for their service on the Company's Board of Directors. In 1999, all other directors (the "non-employee directors"), each of whom serve on the Boards of the Company, IES, IPC, WP&L and AER, received an annual retainer of $32,800 for service on all five Boards. Travel expenses are paid for each meeting day attended. All non-employee directors were also eligible to receive a 25 percent Company matching contribution in common stock for limited optional cash purchases, up to $10,000, of the Company's common stock through the Company's Shareowner Direct Plan. Matching contributions of $2,500 each for calendar year 1999 were made for the following directors: A. B. Arends, R. G. Flowers, J. L. Hanes, K. C. Lyall, A. M. Nemirow, M. E. Neshek, J. D. Pyle, R. D. Ray and R. W. Schlutz. Beginning in 2000, the annual retainer for each non-employee director has been increased to $45,000 for service on all five Boards. Of that amount, $25,000 will be paid in cash and $20,000 will be paid in the Company's common stock. The directors have the option to receive each amount outright (in cash and stock), to have each amount deposited to their Shareowner Direct Plan account or to a directors' Deferred Compensation Account or any combination thereof. Effective April 21, 2000, Mr. Liu will retire as an employee of the Company and will be eligible to receive this annual retainer. Director's Deferred Compensation Plan Under the Directors' Deferred Compensation Plan, directors may elect to defer all or part of their retainer fee. Amounts deposited to a Deferred Compensation Interest Account earn interest at a rate which is equal to the greater of the prime rate as reported in The Wall Street Journal, provided that in no event shall the rate of interest credited for any plan year be greater than 12% or less than 6%. The balance credited to a director's Deferred Compensation Interest Account as of any date will be the accumulated deferred cash compensation and interest that are credited to such account as of such date. Amounts deposited to a Company Stock Account, whether they be the cash portion or the stock portion of the directors' compensation, will earn dividends and those dividends will be reinvested. Annually, the director may elect that, upon retirement or resignation from the Board, the Deferred Compensation Account will be paid in a lump sum or in annual installments for up to 10 years. Director's Charitable Award Program The Company maintains a Director's Charitable Award Program for the members of its Board of Directors beginning after three years of service. The purpose of the Program is to recognize the interest of the Company and its directors in supporting worthy institutions, and to enhance the Company's director benefit program so that the Company is able to continue to attract and retain directors of the highest caliber. Under the Program, when a director dies, the Company will donate a total of $500,000 to one qualified charitable organization, or divide that amount among a maximum of four qualified charitable organizations, selected by the individual director. The individual director derives no financial benefit from the Program. All deductions for charitable contributions are taken by the Company, and the donations are funded by the Company through life insurance policies on the directors. Over the life of the Program, all costs of donations and premiums on the life insurance policies, including a return of the Company's cost of funds, will be recovered through life insurance proceeds on the directors. The Program, over its life, will not result in any material cost to the Company. -13- Director's Life Insurance Program The Company maintains a split-dollar Director's Life Insurance Program for non-employee directors, beginning after three years of service, which provides a maximum death benefit of $500,000 to each eligible director. Under the split-dollar arrangement, directors are provided a death benefit only and do not have any interest in the cash value of the policies. The Life Insurance Program is structured to pay a portion of the total death benefit to the Company to reimburse the Company for all costs of the program, including a return on its funds. The Life Insurance Program, over its life, will not result in any material cost to the Company. The imputed income allocations reported for each director in 1999 under the Director's Life Insurance Program were as follows: A. B. Arends- $306, R. G. Flowers-$442, J. L. Hanes-$485, K. C. Lyall-$391, A. M. Nemirow-$56, M. E. Neshek-$989, J. R. Newman-$689, and J. D. Pyle-$91, R. D. Ray-$746 and A. R. Weiler- $159. Pension Arrangements Prior to the Merger, Mr. Liu participated in the IES Industries retirement plan, which plan was transferred to Alliant Energy Corporate Services, Inc., a subsidiary of the Company ("Alliant Energy Corporate Services") in connection with the Merger. Mr. Liu's benefits under the plan have been "grandfathered" to reflect the benefit plan formula in effect at the time of the Merger. See "Retirement and Employee Benefit Plans-IES Industries Pension Plan." Alliant Energy Corporate Services also maintains a non-qualified Supplemental Retirement Plan ("SRP") for eligible former officers of IES Industries who elected to remain under this plan following the Merger. Mr. Liu participates in the SRP. The SRP generally provides for payment of supplemental retirement benefits equal to 75% of the officer's base salary in effect at the date of retirement, reduced by benefits receivable under the qualified retirement plan, for a period not to exceed 15 years following the date of retirement. The SRP also provides for certain death benefits to be paid to the officer's designated beneficiary and benefits if an officer becomes disabled under the terms of the qualified retirement plan. Certain Agreements Mr. Liu has an employment agreement with the Company, pursuant to which Mr. Liu will serve as Chairman of the Board of the Company until April 21, 2000. Mr. Liu will thereafter retire as Chairman of the Board of the Company, although he will continue to serve as a director. Mr. Liu's employment agreement provides that he receive an annual base salary of not less than $400,000, and supplemental retirement benefits and the opportunity to earn short-term and long-term incentive compensation (including stock options, restricted stock and other long-term incentive compensation) in amounts no less than he was eligible to receive from IES Industries before the effective time of the Merger. If the employment of Mr. Liu is terminated without cause (as defined in the employment agreement) or if Mr. Liu terminates his employment for good reason (as defined in the employment agreement), then the Company or its affiliates will continue to provide the compensation and benefits called for by the employment agreement through the end of the term of such employment agreement (with incentive compensation based on the maximum potential awards and with any stock compensation paid in cash), and all unvested stock compensation will vest immediately. If Mr. Liu dies or becomes disabled, or terminates his employment without good -14- reason, during the term of his respective employment agreement, then the Company or its affiliates will pay to Mr. Liu or his beneficiaries or estate all compensation earned through the date of death, disability or such termination (including previously deferred compensation and pro rata incentive compensation based upon the maximum potential awards). If Mr. Liu is terminated for cause, then the Company or its affiliates will pay his base salary through the date of termination plus any previously deferred compensation. However, if any payments to Mr. Liu under his employment agreement or otherwise are subject to the excise tax on excess parachute payments under the Internal Revenue Code of 1986, as amended (the "Code"), then the total payments to be made under Mr. Liu's employment agreement will be reduced so that the value of these payments he is entitled to receive is $1 less than the amount that would subject Mr. Liu to the 20% excise tax imposed by the Code on certain excess payments, or which the Company may pay without loss of deduction under the Code. Mr. Stoppelmoor entered into a three-year consulting arrangement with the Company in connection with the Merger. Under the terms of his consulting arrangement, Mr. Stoppelmoor receives an annual fee of $324,500 during each of the first two years and a fee of $200,000 during the third year of the consulting period. Mr. Stoppelmoor is also entitled to participate in compensation plans equivalent to those provided the Company's Chairman of the Board and Chief Executive Officer during the consulting period, subject to approval by the Compensation and Personnel Committee of the Board. Although Mr. Stoppelmoor is eligible to participate in the Directors Charitable Award Program and the Directors Life Insurance Program as a result of his service as Vice Chairman of the Board of Directors, his consulting arrangement provides that he will not be eligible to receive any other compensation otherwise payable to directors of the Company. -15- OWNERSHIP OF VOTING SECURITIES Listed in the following table are the number of shares of the Company's common stock beneficially owned by the executive officers listed in the Summary Compensation Table and all nominees and directors of the Company, as well as the number of shares owned by directors and executive officers as a group as of December 31, 1999.

The 1999 bonuses were earned in 1999 and paid in 2000. (2) Other Annual Compensation for 1999 consists of income tax gross-ups for reverse split-dollar life insurance. (3) Prior to the Merger, IES Industries historically made awards of restricted stock. Certain of these awards vested automatically upon the consummation of the Merger. The number of shares of restricted stock reflected in this table that were subject to such automatic vesting consist of 1,006 shares awarded Mr. Hoffman for 1997. In addition, 3,984 restricted shares were awarded to Mr. Hoffman in 1997 which will vest on December 31, 2000. Dividends are paid to Mr. Hoffman on the shares of restricted stock granted in 1997. In 1999, restricted stock was awarded under the Alliant Energy Corporation Long-Term Equity Incentive Plan as follows: Mr. Harvey - 9,294 shares, Mr. Hoffman - 9,294 shares and Mr. Protsch - 9,294 shares. Dividends on shares of restricted stock granted under the Long-Term Equity Incentive Plan are held in escrow and reinvested in shares of common stock pending vesting of the underlying restricted stock. In the event that such restricted stock vests, the participant is then also entitled to receive the common stock into which the dividends on the restricted stock were reinvested. The amounts shown in the table above represent the market value of the restricted stock on the date of grant. The number of shares of restricted stock held by the officers identified in the table and the market value of such shares as of December 31, 1999 were as follows: Mr. Harvey - 9,294 shares ($255,585), Mr. Hoffman - 13,278 shares ($365,145) and Mr. Protsch - 9,294 shares ($255,585). -17- (4) Awards made in 1999 were in combination with performance share awards as described in the table entitled "Long-Term Incentive Awards in 1999".

Options were granted on June 1, 1999, and will fully vest on January 1, 2002. Upon a "change in control" of the Company as defined in the Plan or upon retirement, disability or death of the option holder, these options will become immediately exercisable. (2) The hypothetical potential appreciation shown for the named executives is required by rules of the Securities and Exchange Commission ("SEC"). The amounts shown do not represent the historical or expected future performance of the Company's common stock. In order for the named executives to realize the potential values set forth in the 5% and 10% columns in the table above, the price per share of the Company's common stock would be $48.67 and $77.50, respectively, as of the expiration date of the options. -19- The following table provides information for the executives named below regarding the number and value of exercisable and unexercised options. None of the executives exercised options in fiscal 1999.

Walker 2,870 1/1/02 1,435 2,870 5,740 (1) Consists of performance shares awarded under the Company's Long-Term Equity Incentive Plan. These performance shares will vest based on achievement of specified Total Shareholder Return (TSR) levels as compared with an investor-owned utility peer group over the period ending January 1, 2002. Payouts will be made on a one-for-one basis in shares of Company common stock or cash, subject to modification pursuant to a performance multiplier which ranges from 0 to 2.00. -20- CERTAIN AGREEMENTS AND TRANSACTIONS Mr. Davis has an employment agreement with the Company, pursuant to which Mr. Davis will serve as the Chief Executive Officer of the Company until April 21, 2003. Mr. Davis will also begin serving as the Chairman of the Company effective April 21, 2000. Following the expiration of the initial term of Mr. Davis' employment agreement, his agreement will automatically renew for successive one-year terms, unless either Mr. Davis or the Company gives prior written notice of his or its intent to terminate the agreement. Mr. Davis will also serve as Chief Executive Officer of each subsidiary of the Company until at least April 21, 2001 and as a director of such companies during the term of his employment agreement. Pursuant to Mr. Davis' employment agreement, he is paid an annual base salary of not less than $450,000. Mr. Davis also has the opportunity to earn short-term and long-term incentive compensation (including stock options, restricted stock and other long-term incentive compensation) in amounts no less than he was eligible to receive before the effective time of the Merger, as well as supplemental retirement benefits (including continued participation in the WP&L Executive Tenure Compensation Plan) in an amount no less than he was eligible to receive before the effective time of the Merger, and life insurance providing a death benefit of three times his annual salary. If the employment of Mr. Davis is terminated without cause (as defined in the employment agreement) or if Mr. Davis terminates his employment for good reason (as defined in the employment agreement), the Company or its affiliates will continue to provide the compensation and benefits called for by the employment agreement through the end of the term of such employment agreement (with incentive compensation based on the maximum potential awards and with any stock compensation paid in cash), and all unvested stock compensation will vest immediately. If Mr. Davis dies or becomes disabled, or terminates his employment without good reason, during the term of his respective employment agreement, the Company or its affiliates will pay to Mr. Davis or his beneficiaries or estate all compensation earned through the date of death, disability or such termination (including previously deferred compensation and pro rata incentive compensation based upon the maximum potential awards). If Mr. Davis is terminated for cause, the Company or its affiliates will pay his base salary through the date of termination plus any previously deferred compensation. Under Mr. Davis' employment agreement, if any payments thereunder constitute an excess parachute payment under the Code, the Company will pay to Mr. Davis the amount necessary to offset the excise tax and any applicable taxes on this additional payment. The Company currently has in effect key executive employment and severance agreements (the "KEESAs") with certain executive officers of the Company (including Messrs. Davis, Harvey, Hoffman, Protsch and Walker). The KEESAs provide that each executive officer who is a party thereto is entitled to benefits if, within five years after a change in control of the Company (as defined in the KEESAs), the officer's employment is ended through (i) termination by the Company, other than by reason of death or disability or for cause (as defined in the KEESAs), or (ii) termination by the officer due to a breach of the agreement by the Company or a significant change in the officer's responsibilities, or (iii) in the case of Mr. Davis' agreement, termination by Mr. Davis following the first anniversary of the change of control. The benefits provided are (i) a cash termination payment of two or -21- three times (depending on which executive is involved) the sum of the officer's annual salary and his or her average annual bonus during the three years before the termination and (ii) continuation for up to five years of equivalent hospital, medical, dental, accident, disability and life insurance coverage as in effect at the time of termination. Each KEESA for executive officers below the level of Executive Vice President provides that if any portion of the benefits under the KEESA or under any other agreement for the officer would constitute an excess parachute payment for purposes of the Code, benefits will be reduced so that the officer will be entitled to receive $1 less than the maximum amount which he or she could receive without becoming subject to the 20% excise tax imposed by the Code on certain excess parachute payments, or which the Company may pay without loss of deduction under the Code. The KEESAs for the Chief Executive Officer and the Executive Vice Presidents (including Messrs. Davis, Harvey, Hoffman, Protsch and Walker) provide that if any payments thereunder or otherwise constitute an excess parachute payment, the Company will pay to the appropriate officer the amount necessary to offset the excise tax and any additional taxes on this additional payment. Mr. Davis' employment agreement as described above limits benefits paid thereunder to the extent that duplicate payments would be provided to him under his KEESA. -22- RETIREMENT AND EMPLOYEE BENEFIT PLANS Alliant Energy Corporate Services Retirement Plans Salaried employees (including officers) of the Company are eligible to participate in a Retirement Plan maintained by Alliant Energy Corporate Services. In 1998, the Retirement Plan was amended to implement a cash balance format, thereby changing the benefit calculation formulas and adding a lump sum distribution option for eligible participants. The Alliant Energy Cash Balance Pension Plan (the "Plan") bases a participant's defined benefit pension on the value of a hypothetical account balance. For individuals participating in the Plan as of August l, 1998, a starting account balance was created equal to the present value of the benefit accrued as of December 31, 1997, under the Plan's benefit formula prior to the change to a cash balance approach. That formula provided a retirement income based on years of credited service and final average compensation for the 36 highest consecutive months, with a reduction for a Social Security offset. In addition, individuals participating in the Plan as of August 1, 1998 received a special one-time transition credit amount equal to a specified percentage varying with age multiplied by credited service and base pay. For 1998 and thereafter, a participant receives annual credits to the account equal to 5% of base pay (including certain incentive payments, pre-tax deferrals and other items), plus an interest credit on all prior accruals equal to 4% plus a share of the gain on the investment return on assets in the trust investment for the year. The life annuity payable under the Plan is determined by converting the hypothetical account balance credits into annuity form. Individuals who were participants in the Plan on August 1, 1998 are in no event to receive any less than what would have been provided under the prior formula, had it continued, if they terminate on or before August 1, 2008, and do not elect to commence benefits before the age of 55. All of the individuals listed in the Summary Compensation Table who participate in the Plan (Messrs. Davis, Protsch and Harvey) are "grandfathered" under the prior plans benefit formula. Since their estimated benefits under that formula are higher than under the Plan formula, utilizing current assumptions, their benefits would currently be determined by the prior plan benefit formula. Contributions to the "grandfathered" plan are determined actuarially, computed on a straight-life annuity basis, and cannot be readily calculated as applied to any individual participant or small group of participants. For purposes of the Plan, compensation means payment for services rendered, including vacation and sick pay, and is substantially equivalent to the salary amounts reported in the foregoing Summary Compensation Table. Plan benefits depend upon length of Plan service (up to a maximum of 30 years), age at retirement and amount of compensation (determined in accordance with the Plan) and are reduced by up to 50 percent of Social Security benefits. Credited years of service under the Plan for covered persons named in the foregoing Summary Compensation Table are as follows: Erroll B. Davis, Jr., 20 years; Eliot G. Protsch, 20 years; and William D. Harvey, 12 years. Assuming retirement at age 65, a Plan participant (in conjunction with the Unfunded Excess Plan described below) would be eligible at retirement for a maximum annual retirement benefit as follows: -23- Retirement Plan Table Average Annual Benefit After Specified Years in Plan* Annual Compensation 5 10 15 20 25 30 -------------- ------------------------------------------------------------------------------ $ 125,000 $ 10,085 $ 20,171 $ 30,256 $ 40,341 $ 50,427 $ 60,512 150,000 12,377 24,754 37,131 49,508 61,885 74,262 200,000 16,960 33,921 50,881 67,841 84,802 101,762 250,000 21,544 43,087 64,631 86,175 107,718 129,262 300,000 26,127 52,254 78,381 104,508 130,635 156,762 350,000 30,710 61,421 92,131 122,841 153,552 184,262 400,000 35,294 70,587 105,881 141,175 176,468 211,762 450,000 39,877 79,754 119,631 159,508 199,385 239,262 475,000 42,169 84,337 126,506 168,675 210,843 253,012 500,000 44,460 88,921 133,381 177,841 222,302 266,762 525,000 46,752 93,504 140,256 187,008 233,760 280,512 550,000 49,044 98,087 147,131 196,175 245,218 294,262 600,000 53,627 107,254 160,881 214,508 268,135 321,762 650,000 58,210 116,421 174,631 232,841 291,052 349,262 700,000 62,794 125,587 188,381 251,175 313,968 376,762 __________ * Average annual compensation is based upon the average of the highest 36 consecutive months of compensation. The Plan benefits shown above are net of estimated Social Security benefits and do not reflect any deductions for other amounts. The annual retirement benefits payable are subject to certain maximum limitations (in general, average annual compensation cannot exceed $160,000 for 1999) under the Code. Amounts that would not otherwise be payable under the Plan due to this limit are payable under the Unfunded Excess Plan described below. Under the Plan, if a Plan participant dies prior to retirement, the designated survivor of the participant is entitled to a monthly income benefit equal to approximately 50 percent of the monthly retirement benefit which would have been payable to the participant under the Plan. -24- IES Industries Pension Plan Prior to the Merger, Messrs. Hoffman and Walker participated in the IES Industries retirement plan (which plan was transferred to Alliant Energy Corporate Services in connection with the Merger). Plan benefits payable to Messrs. Hoffman and Walker have been "grandfathered" to reflect the benefit plan formula in effect at the time of the Merger. Mr. Hoffman has four years of credited service under this plan and Mr. Walker has three years of credited service. Maximum annual benefits payable at age 65 to participants who retire at age 65, calculated on the basis of straight life annuity, are illustrated in the following table.

The Unfunded Excess Plan provides an amount equal to the difference between the actual pension benefit payable under the pension plan and what such pension benefit would be if calculated without regard to any limitation imposed by the Code on pension benefits or covered compensation. Unfunded Executive Tenure Compensation Plan-Alliant Energy Corporate Services maintains an Unfunded Executive Tenure Compensation Plan to provide incentive for key executives to remain in the service of the Company by providing additional compensation which is payable only if the executive remains with the Company until retirement (or other termination if approved by the Board of Directors). In the case of the Chief Executive Officer only, in the event that the Chief Executive Officer (1) is terminated under his employment agreement with the Company as described above other than for cause, death or disability (as those terms are defined in the employment agreement), (2) terminates his employment under the employment agreement for good reason (as such term is defined in the employment agreement), or (3) is terminated as a result of a failure of the employment agreement to be renewed automatically pursuant to its terms (regardless of the reason for such non-renewal), then for purposes of the plan, the Chief Executive Officer shall be deemed to have retired at age 65 and shall be entitled to benefits under the plan. Participants in the plan must be designated by the Chief Executive Officer of the Company and approved by its Board of Directors. Mr. Davis was the only active participant in the plan as of -25- December 31, 1999. The plan provides for monthly payments to a participant after retirement (at or after age 65, or with Board approval, prior to age 65) for 120 months. The payments will be equal to 25 percent of the participant's highest average salary for any consecutive 36-month period. If a participant dies prior to retirement or before 120 payments have been made, the participant's beneficiary will receive monthly payments equal to 50 percent of such amount for 120 months in the case of death before retirement, or if the participant dies after retirement, 50 percent of such amount for the balance of the 120 months. Annual benefits of $145,000 would be payable to Mr. Davis upon retirement, assuming he continues in Alliant Energy Corporate Services' service until retirement at the same salary as was in effect on December 31, 1999. Alliant Energy Corporate Services Supplemental Executive Retirement Plan The Company maintains an unfunded Supplemental Executive Retirement Plan to provide incentive for key executives to remain in the service of the Company by providing additional compensation which is payable only if the executive remains with the Company until retirement, disability or death. Participants in the plan must be approved by the Compensation and Personnel Committee of the Board. The plan provides for payments of 60% of the participant's average annual earnings (base salary and bonus) for the highest paid three years out of the last ten years of the participant's employment reduced by the sum of benefits payable to the officer from the officer's defined benefit plan. The normal retirement date under the plan is age 62 with at least ten years of service and early retirement is at age 55 with at least ten years of service. If a participant retires prior to age 62, the 60% payment under the plan is reduced by 3% per year for each year the participant's retirement date precedes his/her normal retirement date. The actuarial reduction factor will be waived for senior officers who have attained age 55 and have a minimum of ten years of service in a senior executive position with the Company. Benefit payments under the plan will be made for the lifetime of the senior officer, with a minimum of 12 years of payments if the participant dies after retirement. A postretirement death benefit of one times the senior executive officer's final average earnings at the time of retirement will be paid to the designated beneficiary. Messrs. Davis, Harvey, Hoffman, Protsch and Walker are participants in this plan. The following table shows payments under the plan, assuming a minimum of 10 years of service at retirement age. -26- Supplemental Executive Retirement Plan Table Average Compensation <10 Years >10 Years* ------------- ------------- ------------- $ 125,000 $ 0 $ 75,000 150,000 0 90,000 200,000 0 120,000 250,000 0 150,000 300,000 0 180,000 350,000 0 210,000 400,000 0 240,000 450,000 0 270,000 500,000 0 300,000 550,000 0 330,000 600,000 0 360,000 650,000 0 390,000 700,000 0 420,000 750,000 0 450,000 __________ * Reduced by the sum of the benefit payable from the applicable defined benefit plan. Key Employee Deferred Compensation Plan-The Company maintains an unfunded Key Employee Deferred Compensation Plan under which participants may defer up to 100% of base salary or incentive compensation. The Company matches up to 50% of the employee deferral (plus 401(k) contributions up to 6% of pay, less 401(k) matching contributions). The deferrals and matching contributions received an annual return to the A-utility bond rate with a minimum return no less than the prime interest rate published in the Wall Street Journal. Payments from the plan may be made in lump sums or installments at the election of the participant. Participants are selected by the Chief Executive Officer of Alliant Energy Corporate Services. Messrs. Davis, Harvey, Protsch and Walker participate in the Plan. -27- REPORT OF THE COMPENSATION AND PERSONNEL COMMITTEE ON EXECUTIVE COMPENSATION To Our Shareowners: The Compensation and Personnel Committee (the "Committee") of the Board of Directors of the Company is currently comprised of four non-employee directors. The Committee assesses the effectiveness and competitiveness of, approves the design of, and administers executive compensation programs within a consistent total compensation framework for the Company. The Committee also reviews and approves all salary arrangements and other remuneration for executives, evaluates executive performance, and considers related matters. To support the Committee in carrying out its mission, an independent consultant is engaged to provide assistance to the Committee. The Committee is committed to implementing a total compensation program for executives that furthers the Company's mission. Therefore, the Committee adheres to the following compensation policies, which are intended to facilitate the achievement of the Company's business strategies. - - Total compensation should enhance the Company's ability to attract, retain and encourage the development of exceptionally knowledgeable and experienced executives, upon whom, in large part, the successful operation and management of the Company depends. - - Base salary levels should be targeted at a competitive market range paid to executives of comparable companies. Specifically, the Committee targets the median (50th percentile) of equally weighted data from utility and general industry companies. - - Incentive compensation programs should strengthen the relationship between pay and performance by emphasizing variable, at-risk compensation that is consistent with meeting predetermined Company, subsidiary, business unit and individual performance goals. In addition, incentive levels are targeted at the median (50th percentile) of equally weighted data from utility and general industry companies. Components of Compensation The major elements of the Company's executive compensation program are base salary, short-term (annual) incentives and long-term (equity) incentives. These elements are addressed separately below. In setting the level for each major component of compensation, the Committee considers all elements of an executive's total compensation package, including employee benefit and perquisite programs. The Committee's goal is to provide an overall compensation package for each executive officer that is competitive to the packages offered other executives. The Committee has determined that total executive compensation, including that for Mr. Davis, is in line with competitive salaries of the comparison groups of companies. Base Salaries The Committee annually reviews each executive's base salary. Base salaries are targeted at a competitive market range (i.e., at the median level) when comparing both utility and non-utility (general industry) data. Base salaries are adjusted annually by the Committee to recognize changes in the market, varying levels of responsibility, prior experience and breadth of knowledge. Increases to base salaries are driven primarily by market adjustments for a particular salary level, which generally limit across-the-board increases. Individual performance factors are not considered by the Committee in setting base salaries. In 1999, the Committee reviewed executive salaries for market comparability using utility and general industry data contained in compensation surveys published by Edison Electric Institute, American Gas Association and several compensation-consulting firms. The Committee decided to maintain Mr. Davis' 1999 base salary at the level established in May 1998. The Summary Compensation Table reflects an annual salary of $580,000 effective May 1, 1998 with compensation from January through April 1998 at the previous annual salary of $450,000 annually. -28- Short-Term Incentives The goal of the Company's short-term (annual) incentive programs is to promote the Committee's pay-for-performance philosophy by providing executives with direct financial incentives in the form of annual cash or stock based bonuses based on the achievement of corporate, subsidiary, business unit and individual performance goals. Annual bonus opportunities allow the Committee to communicate specific goals that are of primary importance during the coming year and motivate executives to achieve these goals. The Committee on an annual basis reviews and approves the program's performance goals and the relative weight assigned to each goal as well as targeted and maximum award levels. A description of the short-term incentive programs available during 1999 to executive officers follows. Alliant Energy Corporation Management Incentive Compensation Plan-In 1999, the Alliant Energy Corporation Management Incentive Compensation Plan (the "MICP") covered utility executives and was based on achieving annual targets in corporate performance that included an earnings per share ("EPS") target for the utility businesses, and business unit and individual performance goals. Target and maximum bonus awards under the MICP in 1999 were set at the median of the utility and general industry market levels. Targets were considered by the Committee to be achievable, but required above-average performance from each of the executives. Actual payment of bonuses, as a percentage of annual salary, is determined by the level of performance achieved in each category. Weighting factors are applied to the percentage achievement under each category to determine overall performance. If a pre-determined EPS target is not met, there is no bonus payment associated with the MICP. If the threshold performance for any other performance target is not reached, there is no bonus payment associated with that particular category. Once the designated maximum performance is reached, there is no additional payment for performance above the maximum level. The actual percentage of salary paid as a bonus, within the allowable range, is equal to the weighted average percent achievement for all the performance categories. Potential MICP awards for eligible executives range from 0 to 90 percent of annual salary. The amounts paid under the MICP to eligible officers included in the Summary Compensation Table are reflected in that table. In 1999, Mr. Davis was covered by the MICP. Awards for Mr. Davis under the MICP in 1999 were based on corporate and strategic goal achievement in relation to predetermined goals. For each plan year, the Committee determines the performance apportionment for Mr. Davis. In 1999, that apportionment was 70 percent for corporate performance and 30 percent for strategic goal performance. Corporate performance is measured based on a Company-wide EPS target established at the beginning of the year. Strategic goals are measured based on the achievement of certain specific goals, which included strategy development and implementation, established for Mr. Davis by the Committee. The 1999 MICP award range for Mr. Davis was from 0 to 120 percent of annual salary. Bonuses under the MICP are earned and calculated in a manner similar to that employed by the MICP. The award earned by Mr. Davis under the MICP for 1999 is set forth in the Summary Compensation Table. -29- Alliant Energy Resources Annual Incentive Plan-The Alliant Energy Resources Annual Incentive Plan for 1999 covered non-utility executives and was based on achieving annual targets in corporate performance (that included an EPS target for the non-utility businesses), business unit performance (that included the contribution to EPS by such business unit) and group, unit and individual performance goals. Target and maximum bonus awards were set at competitive market levels. Targets were considered by the Committee to be achievable, but required above-average performance from each of the executives. Actual payment of bonuses, as a percentage of annual salary, is determined by the level of performance achieved in each category. Weighting factors are applied to the percentage achievement under each category to determine overall performance. If the business unit's EPS contribution to corporate is below the threshold level, there is no bonus payment associated with the plan. If the threshold performance for any other performance target is not reached, there is no bonus payment associated with that particular category. Once the designated maximum performance is reached for any other performance target, there is no additional payment for performance above the maximum level. The actual percentage of salary paid as a bonus, within the allowable range, is equal to the weighted average percent achievement for all the performance categories. Potential Alliant Energy Resources Annual Incentive Plan awards for executives range from 0 to 60 percent of annual salary. The amounts paid under the Alliant Energy Resources Annual Incentive Plan to eligible officers included in the Summary Compensation Table are reflected in that table. Long-Term Incentives The Committee strongly believes compensation for executives should include long-term, at-risk pay to strengthen the alignment of the interests of the shareowners and management. In this regard, the Alliant Energy Corporation Long- Term Equity Incentive Plan permits grants of stock options, restricted stock and performance unit/shares with respect to the Company's common stock. The Committee believes the Long-Term Equity Incentive Plan balances the Company's existing compensation programs by emphasizing compensation based on the long- term successful performance of the Company from the perspective of the shareowners. A description of the long-term incentive programs available during 1999 to executive officers under the Long-Term Equity Incentive Plan is set forth below. Alliant Energy Corporation Long-Term Incentive Program-The Alliant Energy Corporation Long-Term Incentive Program covered utility executives and consisted of the following components: stock options and performance shares. Stock options provide a reward that is directly tied to the benefit shareowners receive from increases in the price of the Company's common stock. The payout from the performance shares is based on the Company's three-year total return to shareowners relative to an investor-owned utility peer group. Thus, the two components of the Long-Term Incentive Program (i.e. stock options and performance shares) provide incentives for management to produce superior shareowner returns on both an absolute and relative basis. During 1999, the Committee made a grant of stock options and performance shares to various executive officers, including Messrs. Davis, -30- Harvey, Hoffman, Protsch and Walker. All option grants had per share exercise prices equal to the fair market value of a share of Company common stock on the date the grants were approved. Options vest on a one-third basis at the beginning of each calendar year after grant and have a ten-year term from the date of the grant. Executives in the Alliant Energy Corporation Long-Term Equity Incentive Program were also granted performance shares. Performance shares will be paid out in shares of the Company's common stock or cash. The award will be modified by a performance multiplier which ranges from 0 to 2.00 based on the three-year average of the Company's total shareowner return relative to an investor-owned utility peer group. In determining actual award levels under the Alliant Energy Corporation Long-Term Equity Incentive Program, the Committee was primarily concerned with providing a competitive total compensation level to officers. As such, award levels (including awards made to Mr. Davis) were based on a competitive analysis of similarly sized utility companies that took into consideration the market level of long-term incentives, as well as the competitiveness of the total compensation package. Award ranges, as well as individual award levels, were then established based on responsibility level and market competitiveness. No corporate or individual performance measures were reviewed in connection with the awards of options and performance shares. Award levels were targeted to the median of the range of such awards paid by comparable companies. In addition, the Committee did not consider the amounts of options and performance shares already outstanding or previously granted when making awards for 1999. Mr. Davis' awards in 1999 under this program are shown in the Stock Options/SAR Grants in 1999 Table and the Long-Term Incentive Awards in 1999 Table. Alliant Energy Resources Long-Term Incentive Program-The Alliant Energy Resources Long-Term Incentive Program covered non-utility executives and consisted of the following components: stock options and performance shares. Stock options provide a reward that is directly tied to the benefit shareowners receive from increases in the price of the Company's common stock. The payout from the performance shares is contingent upon achievement of specified AER earnings growth. Thus, the two components of the Alliant Energy Resources Long- Term Incentive Program, (i.e. stock options and performance shares) provide incentives for management to produce superior shareowner returns on both an absolute and relative basis. All option grants had a per share exercise price equal to the fair market value of a share of Company common stock on the date the grants were approved. Options vest on a one-third basis at the beginning of each calendar year and have a ten-year term from the date of the grant. Executives in the Alliant Energy Resources Long-Term Incentive Program were also granted performance shares. Performance shares will be paid out in shares of the Company's common stock. The payment will be modified by a performance multiplier which ranges from 0 to 2.00 based on the AER three-year average growth in EPS contribution to the Company's EPS. In determining actual award levels, the Committee was primarily concerned with providing a competitive total compensation level to officers. As such, award levels were based on a competitive analysis of similarly-sized general industry companies that took into consideration the market level of long-term incentives, as well as the competitiveness of the total compensation package. Award ranges, as well as individual award levels, were then established based on responsibility level and market competitiveness. No corporate or individual performance measures were reviewed in connection with the awards of options and performance shares. Award levels were targeted to the median of the range of such awards paid by comparable companies. In addition, the Committee did not consider the amounts of options and performance units already outstanding or previously granted when making awards for 1999. -31- Special Restricted Stock Awards in 1999 To provide selected executives of the Company with severance arrangements with generally comparable terms relating to any future change in control of the Company, the Company in 1999 offered new key executive employment and severance agreements (the "New KEESAs") to such executive officers of the Company (including Messrs. Davis, Harvey, Hoffman, Protsch and Walker). To receive a New KEESA, each executive officer (other than Mr. Davis) was required to cancel existing rights under his or her prior key executive employment and severance agreement in exchange for a grant of restricted stock. Mr. Davis did not receive a grant of restricted stock in connection with the cancellation of his prior key executive employment and severance agreement. Mr. Walker also did not receive a restricted stock grant because he did not have a prior key executive employment and severance agreement under which the existing rights were cancelled. The grants of restricted stock were valued at one times salary for Executive Vice Presidents of the Company (including Messrs. Harvey, Hoffman and Protsch) and one-half times salary for Vice Presidents of the Company. Subject to certain exceptions, the restricted stock will vest only if the executive remains with the Company for a period of at least three years. Stock Ownership Guidelines In January 1999, the Company established stock ownership guidelines for executive officers as a way to better align the financial interests of its officers with those of its shareowners. These officers are expected to make continuing progress towards compliance with these guidelines and to comply fully with the guidelines within five years of implementation. Officers are required to own stock with a value equal to a specified multiple of their base salaries. Under these guidelines, the requisite multiples are three for the Chief Executive Officer and Executive Vice Presidents and 1.5 for Vice Presidents. The Chief Executive Officer retains the right to grant special dispensation for hardship, promotions or new hires. Policy with Respect to the $1 Million Deduction Limit Section 162(m) of the Code generally limits the corporate deduction for compensation paid to executive officers named in the proxy statement to $1 million unless such compensation is based upon performance objectives meeting certain regulatory criteria or is otherwise excluded from the limitation. Based on the Committee's commitment to link compensation with performance as described in this report, the Committee currently intends to qualify future compensation paid to the Company's executive officers for deductibility by the Company under Section 162(m). Conclusion The Committee believes the existing executive compensation policies and programs provide the appropriate level of competitive compensation for the Company's executives. In addition, the Committee believes that the long and short term performance incentives effectively align the interests of executives and shareowners toward a successful future for the Company. COMPENSATION AND PERSONNEL COMMITTEE Arnold M. Nemirow (Chair) Alan B. Arends Judith D. Pyle Anthony R. Weiler -32- COMPARISON OF FIVE YEAR CUMULATIVE TOTAL RETURN Rules of the SEC require that the Company show a graphical comparison of the total return on its common stock for the last five fiscal years with the total returns of a broad market index and a more narrowly focused industry or group index. (Total return is defined as the return on common stock including dividends and stock price appreciation, assuming reinvestment of dividends.) The Company has selected the Standard & Poors (S&P) 500 Index for the broad market index and the S&P Utility Index as the industry index. These indices were selected because of their broad availability and recognition. The following chart compares the total return of an investment of $100 in Company common stock on December 31, 1994, with like returns for the S&P 500 and S&P Utilities indices. Pursuant to SEC rules, the table reflects only information regarding the common stock of the Company (formally known as WPL Holdings, Inc.).

One report covering one transaction was inadvertently filed late on behalf of William D. Harvey. To the best of the Company's knowledge, all required filings in 1999, with the exception of that filing, were properly made in a timely fashion. In making the above statements, the Company has relied on the representations of the persons involved and on copies of their reports filed with the SEC.
