Board   Committees  -  The  membersBoard  of  theDirectors  has  standing   Auditing,
Contributions, Executive, Human Resources and Nominating Committees, the members
of the  Boardwhich are identified in the biographies above.  The Auditing, Human Resources
and Nominating Committees are comprised entirely of outside directors.  Since  the  Ameren  Board  was  not  constituted  until
December 31, 1997, there were no committee meetings held during the
year.

     The general  functions of the Auditing  Committee  include:  (1) reviewing,
with management and the independent  accountants,  the adequacy of the Company's
system of internal accounting  controls;  (2) reviewing the scope and results of
the  annual   examination  and  other  services  performed  by  the  independent
accountants;  (3)  recommending  to the Board  the  appointment  of  independent
accountants and approving fees for the services they perform;  and (4) reviewing
the  scope  of  audits  and  annual  budget  of  the  Company's  internal  audit
department. The Auditing Committee held four meetings in 1998.

     The Contributions Committee makes policies and recommendations with respect
to charitable  and other  contributions.  The  Contributions  Committee held two
meetings in 1998.

     The Executive Committee has such duties as may be delegated to it from time
to time by the Board. The Executive Committee did not meet in 1998.

     The Human Resources  Committee  considers the  qualifications  of executive
personnel  and  recommends  changes  therein,  considers  or  recommends  salary
adjustments  for certain  employees and  considers and acts on important  policy
matters affecting  Company personnel.  The Human Resources Committee  held  four

     The  Nominating  Committee  considers  and  recommends  for Board  approval
candidates  for the Board of Directors,  as  recommended  by  management,  other
members of the Board,  shareholdersstockholders and other interested parties. Item  (2):   Long-Term   Incentive  Plan.  To  further  relate
compensation to performance, the Board of Directors has adopted the
Ameren Corporation  Long-Term  Incentive Plan of 1998 (the "Plan"),
which  shall  become  effective  upon  approval  by  the  Company's
stockholders.  The Plan is substantially the same as a similar plan
approved by Union Electric  shareholders  in 1995 and, absent early
termination,  will  terminate ten years after its  effective  date.
Awards  granted  under the Plan are  expected to be at or below the
median of awards granted by similarly-situated companies.

     Set forth below is a summary of Plan  provisions.  The summary
is  qualified  by  reference  to the full Plan  attached  hereto as
Appendix A.

     Purpose. The Plan is intended to enhance shareholder value by

                                 7





promoting an increased  interest in  the long-term  performance and
profitability of the Company.

     Administration.  The Plan  will be  administered  by the Human
ResourcesNominating
Committee of the Board of Directors  (the  "Committee").
The Committee shall determine the officers, employees and directors
eligible  to  receive  awards  and the  amount  of any  award.  The
Committee  shall  interpret  the Plan and can  adopt  rules  deemed
appropriate. No Plan awards may be made to Committee members unless
approved by the full Board of Directors.

     Shares.  A maximum of 4,000,000 shares of the Company's Common
Stock, $ .01 par value,  ("Common Stock") will be reserved for Plan
purposes,  subject to  appropriate  adjustment  by the Committee to
prevent dilution or enlargement of the rights of Plan participants.
The reserved shares constitute  approximately 2.9% of the Company's
outstanding Common Stock. The maximum number of shares which may be
granted  through  options  or  stock  appreciation  rights  to  any
participant in a calendar year is 200,000 shares.

Award Alternatives.

     A. Performance  Units - rights,  which may be payable in cash,
shares of Common Stock,  other awards, or other property,  which is
contingent  on the  achievement  of  performance  goals  set by the
Committee.

     B. Restricted Stock - rights to receive shares of Common Stock
awarded  as  determined  by the  Committee,  which  shares  will be
subject to transferability or other restrictions.

     C. Options - rights to purchase shares of the Company's Common
Stock,  or other awards or property,  at a specified price during a
prescribed  time period.  The exercise  price for Common Stock will
not be less than the fair market value at the date of the grant. No
option may provide for resetting the exercise price.

     D.  Stock  Appreciation  Rights - the right to  receive a cash
payment  equal  to the  excess  of the  fair  market  value  of the
Company's Common Stock on the date of exercise over the grant price
of the Stock Appreciation  Right. The grant price shall not be less
than the fair market value of the stock on the date of the grant.

     Tax Aspects of the Plan.  The federal tax  consequences  of an
award

                                 8





under the Plan  depend on the  nature of the award. The  grant of a
Restricted Stock or Performance Award  does not immediately  result
in taxable  income to a recipient or a tax deduction to the Company
unless  the  recipient  makes a special  election.  At the time the
shares  of  Common  Stock  are  awarded  and  become  free  of  any
restrictions, a recipient will recognize taxable ordinary income in
an amount equal to the fair market value of the Common  Stock,  and
the  Company  will  be  entitled  to  a  corresponding  income  tax
deduction.  Generally,  during a restriction  period, any dividends
received  with  respect  to an award  will be  taxed as  additional
compensation to the recipient,  and the Company will be entitled to
a corresponding income tax deduction.

     Generally,  an  incentive  stock  option  will not  result  in
taxable  income on the date of grant or  exercise,  and the Company
will not be  entitled  to an income  tax  deduction.  Provided  any
minimum holding periods are satisfied, any gain on a disposition of
stock so acquired will be taxable to a recipient as a capital gain,
and the Company  will not be entitled to any  corresponding  income
tax deduction.  If minimum  holding  periods are not  satisfied,  a
recipient will generally recognize ordinary income in the amount of
the excess of the fair market value of the Common Stock on the date
of the exercise  (or if less,  on the date of sale) over the option
price,  and the Company will be entitled to a corresponding  income
tax  deduction.   Also,   certain  recipients  may  be  subject  to
alternative  minimum tax on the excess of the fair market  value of
the shares over the option price when the incentive stock option is
exercised. The grant of a nonqualified stock option does not result
in  taxable  income  to a  recipient  or a tax  deduction  for  the
Company.  Upon  exercise,  a  recipient  will  generally  recognize
taxable  ordinary  income in an amount  equal to the  excess of the
fair market  value of the Common  Stock on the date of the exercise
over  the  cash  paid,  and  the  Company  will  be  entitled  to a
corresponding income tax deduction.

     General.  Consistent with the goals of the Plan, the Committee
may also grant  other  awards  based or related to the value of the
Common Stock. The term of any option or a stock  appreciation right
granted in tandem therewith may not exceed ten years from the grant
date.  In the  event of a change in  control  of the  Company,  any
outstanding  options and stock  appreciation  rights  become  fully
exercisable, any restrictions on outstanding Restricted Stock shall
be deemed  satisfied,  and all  performance  units  shall be deemed
earned and  payable in full.  The Plan may be revised by the Board,
but any such  change  may not  impair  the  rights of  participants
without their consent.

     The closing  price of the  Company's  Common Stock on March 2,
1998, was $38 7/16.


     The Board  recommends a vote FOR Item 2.  Adoption of the Plan
requires the affirmative vote of a majority of the Common Stock.


     Stockholder  Proposal.  Proponents of the stockholder proposal
described  below  as Item  (3)  notified  Union  Electric  of their
intention to attend the 1998 Annual Meeting to present the proposal
for  consideration  and  action.  The  names and  addresses  of the
proponents  and the number of shares they hold will be furnished by
the  Secretary  of the Company  upon receipt of any oral or written
request therefor.


         Item (3):  Assessment of Decommissioning Costs.

     WHEREAS Union Electric is  responsible  for and liable for the
          ultimate  dismantling of the Callaway Nuclear Power Plant
          and  the  return  of the  plant  site  to  its  original,
          non-radioactive, greenfield condition;

     WHEREAS estimates  for  decommissioning  a reactor the size of
          Callaway  range  all  the way  from  $130  million  to $3
          billion,  according to a 1988 U. S. Government Accounting
          Office report;

     WHEREAS Callaway's Nuclear Regulatory Commission license would
          allow the plant to  operate  for 40 years  (until  2024),
          accidents and/or age-related  degradation of vital safety
          components  have  caused  reactors  to be shut down years
          before their licenses' expiration;

     WHEREAS the longer Callaway operates,  the greater will be the
          accumulation of radioactivity  there, and the higher will
          be the radiation fields within  which demolition  workers
          will  have  to  work  to  dismantle  the  plant,  thereby
          increasing costs, liability, and occupational hazards;

     WHEREAS the longer the plant operates, the greater will be the
          accumulation of irradiated fuel rods which must be stored
          at the  plant  in a fuel  pool  or  dry  casks  requiring
          surveillance  and maintenance  into the infinite  future.
          The fuel rods may someday

          be  transported  to  a federal  deep-geologic  repository  
          though  none has been  finally sited or  constructed, and
          may never be;

     WHEREAS   chelating   agents   are   used   in  the   chemical
          decontamination   of  nuclear   plants  --  to   dissolve
          radioactive  corrosion  products in the  reactor  vessel,
          coolant  systems,  piping  and other  components  -and we
          believe  the long term  effects of the  chelating  agents
          make  them  unacceptable;  they are  known  to cause  the
          accelerated migration of dissolved radioactive wastes out
          of burial trenches into the surrounding environment;

     WHEREAS we believe that no known safe technology exists as yet
          for  the   remote-controlled   segmenting  of  Callaway's
          330-ton,  40-foot- high reactor vessel  contaminated with
          some   substances   that  will  remain   radioactive  for
          thousands of years and longer;

     WHEREAS even if safe technologies were to be developed for the
          dismantling of the Callaway buildings and reactor vessel,
          no safe  disposal  site  may  ever  be  found  for  these
          radioactive    wastes,   and   no   railroad   or   other
          transportation  corridors may exist which would be deemed
          acceptable to the public.


     RESOLVED:  the  shareholders  request  that  the  Company  (1)
          provide for  shareholders  a financial  assessment of the
          comparative costs of decommissioning  Callaway before its
          40-year operating license expires versus operating it for
          the full licensed duration, including such costs as:

          --   the  stockpiling of high- and low-level  radioactive
               wastes for which the company may remain  morally and
               financially liable for an indefinite time;

          --   the need for a greater  number of workers to replace
               worn-out,  embrittled,  malfunctioning  or  obsolete
               components in locations within the plant that become
               increasingly radioactive as the plant ages; and/or

          --   potential accidents;

          (2)  provide a  summary  of this  assessment  in the next
          annual  report and provide a copy of the full  assessment
          to shareholders on request.

                                 11





                        SUPPORTING STATEMENT

     We  believe  an  assessment  of  these  comparative  costs  is
essential  for  realistic  and  responsible  economic  and  ethical
planning.


YOUR BOARD OF DIRECTORS RECOMMENDS A VOTE AGAINST ITEM
(3).

     In   light  of  the   extensive   information   on   estimated
decommissioning  costs  currently  available,  the  Board is of the
opinion  that  developing   additional   information  in  the  form
requested is  unnecessary  and would  increase  expenses  without a
commensurate increase in relevant information.

          o    Information  on  decommissioning  cost  estimates is
               included  in  the  Company's   published   financial
               statements.

          o    The  Missouri  Public  Service  Commission  requires
               updated  decommissioning  cost  studies  every three
               years,  and copies of the studies are  available  to
               the public.

          o    Nuclear Regulatory  Commission  regulations  require
               the  Company  to fund  decommissioning  of  Callaway
               Plant at prescribed  levels,  which are reviewed and
               updated periodically.

          o    Internal reviews are made annually.

          Contrary to assumptions  and  assertions  included in the
          proposal -

          o    Individual  and  collective  radiation  exposure  to
               workers at Callaway Plant is trending downward;

          o    The  range of  decommissioning  cost  estimates  for
               other   nuclear   plants   similar  to  Callaway  is
               consistent with our estimate;

          o    The  performance  of vital safety  components is not
               allowed to degrade and, with proper maintenance, age
               does not threaten continued plant operation;



                                 12





          o    As stated  in the  government's  General  Accounting
               Office   report   referred   to  in  the   proposal,
               "Technology  exists to  decommission  nuclear  power
               plants;"

          o    Through     use    of     advanced     technologies,
               decommissioning  after 40 or more years of operation
               will not  result in higher  occupational  hazards to
               workers.


     The Board  believes  that,  in the  absence of any  compelling
reasons  to make  additional  studies of  Callaway  decommissioning
costs,  additional  expenditures  for  such  information  would  be
imprudent, and therefore recommends voting AGAINST ITEM (3).

     Passage of the  proposal  requires the  affirmative  vote of a
majority of the votes cast.

     Item (4): Other Matters.  The Board of Directors does not know
of any  matters,  other  than the  election  of  directors  and the
proposals set forth above, which may be presented to the meeting.

     Security Ownership. Based on an Amendment No. 1 to Schedule 13
G,  dated  February  10,  1998 and filed  with the  Securities  and
Exchange  Commission  by The  Capital  Group  Companies,  Inc.  and
Capital  Research and Management  Company,  said companies had sole
dispositive  power  over 8,695,000 shares  of  the Company's Common
Stock and no voting power with respect to any such shares. Further,
pursuant  to  Rule  13d-4,  both  companies  disclaimed  beneficial
ownership of the reported  shares.  The reported  shares  represent
approximately 6.3% of the outstanding Common Stock of the Company.

The names and addresses of the proponents and the number of shares they hold will be furnished by the Secretary of the Company upon receipt of any oral or written request for such information. WHEREAS: Nuclear power plants, including Callaway, during routine operation, release into the air and water radioactive wastes which we believe increase the risk of life-shortening illnesses, genetic mutations, and environmental damage; Though the federal government's "permissible" concentration levels govern these releases, we believe "permissible" does not mean safe, but merely expedient; AmerenUE extracts Missouri River water for Callaway's cooling systems, and some of that water becomes radioactively contaminated; Some wastewater streams contaminated with concentrations of radioactivity that exceed permissible federal release standards are placed in storage tanks until some of the shorter-lived isotopes can decay; some wastewater streams are re-filtered before being recycled (within the plant) or are released to the river; some wastewater streams are merely pumped into other waste processing tanks to be diluted with cleaner water before discharge to the river. Instruments monitoring the flow of wastewater batches after discharge are set only to detect gamma-emitting isotopes; some beta emitters (including tritium and noble gases) and alpha emitters can be released without detection. Unfiltered, accidental leaks and releases can also occur through the established liquid effluent pathways; 7 Union ElectricOne contaminant - tritium, a radioactive isotope of hydrogen accumulates in the cooling water as a fission and activation product; Since no economically feasible technology exists to filter tritium from cooling water effluents, it is released in gaseous emissions to the atmosphere and in liquid releases into the Missouri River - 79 miles upstream from St. Louis County's drinking water intake; The medical profession typically decontaminates a lab table for spills of even 90 trillionths (per four-inch square) of one curie of radioactivity. During Callaway's operation in 1997, the Company reported releasing 684.8 curies of tritium in 231 batches of filtered radioactive wastewater into the Missouri River. The company also reported releasing tritium to the atmosphere; Tritium can be ingested or inhaled, potentially causing reproductive, cellular, and genetic damage. Its half-life is 12.3 years; Because tritium and the other radioactive isotopes routinely released from Callaway will continue emitting radiation particles and rays for at least ten half-lives, the impacts of the Callaway liquid wastes on the water, algae, fish and other creatures (including humans)living downstream can be persistent. RESOLVED: shareholders request that Ameren describe, in its next annual report, its efforts to reduce the release of radioactive materials to the air and water during Callaway's routine operation. SUPPORTING STATEMENT Radioactive releases occur during Callaway's routine operation. We believe that the impact of these planned radiation releases, no matter how small, is cumulative, irreversible, and potentially dangerous. In addition, the threat of disastrous accidental releases remains. Ameren should take responsibility for a more complete accounting of all radiation releases, so that the Company and its shareholders can more accurately assess the plant's impact on the biosphere. YOUR BOARD OF DIRECTORS RECOMMENDS A VOTE AGAINST ITEM (2). On-going measurements at Callaway consistently show that plant effluent releases are less than one percent of the levels allowed by current regulations. This low level of effluent releases clearly demonstrates the Company's successful commitment to reduce the level of radioactive material released from the Callaway Plant. Because effluent releases at Callaway are already a small fraction of allowable 8 standards, additional reporting or expenditures by the Company would have minimal impact, and the Board therefore recommends a vote AGAINST ITEM (2). Passage of the proposal requires the affirmative vote of a majority of the votes cast. Item (3): Other Matters The Board of Directors does not know of any matters, other than the election of directors and the proposal set forth above, which may be presented to the meeting. SECURITY OWNERSHIP Based on an Amendment to Schedule 13G filed with the Securities and Exchange Commission on February 11, 1999, Capital Research and Management Company, 333 South Hope Street, Los Angeles, California 90071, had sole dispositive power over 10,385,400 shares of the Company's Common Stock and no voting power with respect to any such shares. Pursuant to Rule 13d-4, such Company disclaimed beneficial ownership of the reported shares. The reported shares represent approximately 7.6% of the outstanding Common Stock of the Company. 9 SECURITY OWNERSHIP OF MANAGEMENT

EXECUTIVE COMPENSATION Ameren Corporation Human Resources Committee Report on Executive Compensation: The Company'sCompensation Ameren Corporation and its subsidiaries' (collectively referred to as "Ameren") goal for executive salaries is to approximate the median of the range of salaries paid by similarly-situated companies. Accordingly, the Human Resources Committee of the Board of Directors of Ameren Corporation, which is comprised entirely of non-employee directors, makes annual reviews of the compensation paid to the Company's executive officers.officers of Ameren. The Committee's salary decisions with respect to the five 10 highest paid officers of Ameren Corporation and each principal subsidiary are subject to approval by thesuch company's Board of Directors. Following the annual reviews, the Committee authorizes appropriate changes as determined by the three basic components of the Company's executive compensation program, which are: o Base salary, o A performance-based incentive plan, and o Long-term stock-based awards. First, in evaluating and setting base salaries for the Company's executive officers, including the Chief Executive Officer,Officers of Ameren Corporation and its subsidiaries, the Committee considers: individual responsibilities, including changes which may have occurred since the prior review; individual performance in fulfilling responsibilities, including the degree of competence and initiative exhibited; relative contribution to the results of Company operations; the impact of conditions under which the Company operated;operating conditions; the effect of economic changes on the Company's salary structure; and comparisons with compensation paid by similarly-situated companies. Such considerations are subjective, and specific measures are not used in the review process. The "similarly-situated companies" used for salary comparisons are included in the EEI Index referred to in the Performance Graph herein. The second component of the Company's executive compensation program is a performance-based Executive Incentive Compensation Plan established by the Ameren Corporation Board, which provides specific, direct relationships between corporate results and Plan compensation. The Plan is designed to encourage achievement of goals and, for 1997, measurable stockholder and customer-related objectives -- specifically goals pertaining to return on equity and control of operating and maintenance expenses and wages --For 1998, Ameren consolidated year-end earnings per share (EPS) target levels were set by the Human Resources Committee. AtIf EPS reaches at least the end of each year the Committee compares results of operations with the targeted objectives. If the objectives are met,minimum target level, the Committee authorizes incentive payments within prescribed ranges based on individual performance and degree of responsibility. 17 If basic corporate objectives are not achieved,EPS fails to reach the minimum target level, no payments are made. Under the Incentive Plan, it is expected that payments to the Chief Executive OfficerOfficers of Ameren Corporation and its subsidiaries will range from zero to 37%0-37% of base salary, and during the past three yearssalary. For 1998, actual payments have averaged 35%ranged from 29% to 36% of base salary. The third component of the 19971998 executive compensation program is the Long-Term Incentive Plan of 1995,1998, which also ties compensation to performance. The Plan was approved by Ameren Corporation shareholders at the 1995its 1998 Annual Meeting and provides for the grant of options, performance dividendawards, stock appreciation rights and/orand other awards. The Human Resources Committee determines who participates in the Plan and the number and types of awards to be made. TheyIt also setsets the terms, conditions, performance requirements and limitations 11 applicable to each award under the Plan. Awards under the 19951998 Plan have been at levels that approximate the median of the range of awards granted by similarly-situated companies. In determining the reported 19971998 compensation of the Chief Executive Officer,Officers, as well as compensation for the other executive officers, the Human Resources Committee considered and applied the factors discussed above. Specific recognition was given to the generally favorable level of 1996 earnings per share, which was achieved despite a rate reduction, significant rate credits to Missouri customers, and continuing expenses related to the merger with CIPSCO Incorporated. Further, the reported compensation reflects an above-average level of achievement in meeting 1997 performance targets for return on equity and control of labor costs and other operating and maintenance expenses. The 1997 salary of the Chief Executive Officer also recognizes the additional experience he has gained in the position since his election as CEO of Union Electric on January 1, 1994.attaining 1998 EPS. Authorized salaries for the Company's executive officers fell within the ranges of those paid by similarly-situated companies. /s/ John Peters MacCarthy, Chairman Thomas A. Hays Robert H. Quenon CIPSGordon R. Lohman Compensation Committee Report on Executive CompensationTables The CIPS executivefollowing tables contain compensation program for 1997 consisted of a base salary and annual incentives which link compensation with corporate performance. Base salary is determined by individual performance relative to specific job responsibilities and by comparisons of salaries for similar jobs 18 in the utility industry. Emphasis is placed on salary data provided by the EEI 100 utility group shown on the Performance Graph herein. The salaryinformation, for the CIPS officer listed inperiods indicated, for (a) the Summary Compensation Table was increased in 1997 by the Compensation CommitteeChairman, President and Chief Executive Officer of the CIPS Board of Directors to track competitive base salaries inCompany and (b) the utility industry and to reflect performance, which is determined subjectively by the Committee based on individual evaluations. Incentive compensation can be earned based on achievementfour other most highly compensated executive officers of the objectives of the annual Management Incentive Plan ("MIP"). It is the Committee's responsibility to administer the MIP and in so doing the CIPS Compensation Committee (1) sets the overall corporate financial performance goal and unit or individual objectives, (2) determines the participants to be included in the plan, and (3) determines the amount of each participant's incentive pay to be based on attainment of the overall corporate goal and the amount to be based on achievement of individual objectives. The corporate goal for 1997 was based on a targeted return on average common stock equity of CIPSCO. Individual objectives related to such areasCompany who were serving as service reliability, public and employee safety, proper maintenance of corporate assets and quantifiable improvements in efficiency and productivity. The base 1997 salary shown in the Summary Compensation table for Mr. Greenwalt reflects the Compensation Committee's consideration of prevailing market levels for executive officers in other comparably-sized utilities, as well as advances toward a more competitive cost structure. Also, increased merger related savings were identified as a resultat the end of continuing focus on efficiencies to be achieved through the merger with Union Electric. With respect to competition and deregulation, it was the Committee's opinion that the company has successfully positioned itself and focused efforts toward promoting principles of reliability, safety and benefits for all parties. As shown in the table, no awards were made in 1997 under the MIP. /s/ G. R. Lohman, Chairman T. L. Shade J. W. Wogsland 191998. 12 SUMMARY COMPENSATION TABLE

(1) For the options shown above, an equal number of dividend rights ("rights") were granted. The rights, which were granted pursuant to the Long-Term Incentive Plan of 1995, provide the opportunity to earn an amount equal to a percentage of the dividends that would have been paid had the participant acquired the shares underlying the stock options. Awards based on the rights are paid, as determined by the Human Resources Committee, based on the Company's results measured over a three-year performance period. The performance period for these rights is from January 1, 1997 to December 31, 1999. The performance measure associated with the rights is the Company's total shareholder return compared to such return for a comparison group consisting of the "Edison Electric Institute Index of 100 Investor-Owned Electrics." Total shareholder return ("TSR") is defined as the sum of the percentage change in the price of the Company's Common Stock and dividends paid (assuming reinvestment) over the performance period. Award payouts, if any, will be determined at the end of the performance period, based upon the Company's three-year TSR ranking against the three-year TSR of the comparison group. Award payouts may range from 50% of dividends paid during the performance period (if the Company's TSR is equal to or greater than 50% of the companies in the comparison group) to 150% of such dividends (if the Company's TSR is equal to or greater than 90% of the companies in the comparison group). If the Company's TSR during the performance period is less than 50% of the companies in the comparison group no awards will be made. (2) Options vest 25% annually beginning February 10, 1999. (3) The Grant Date Present Values were determined using the binomial option pricing model, a derivative of the Black-Scholes option pricing model. Assumptions used for the model are as follows: an option term of ten years, stock volatility of 13.17%, dividend yield of 6.53%, risk-free interest rate of 5.70%, and a vesting restrictions discount rate of 3% per year over the five-year vesting period. 21 The Grant Date Present Value calculation is presented in accordance with SEC proxy requirements, and the Company has no way to determine whether the pricing model can properly determine the value of an option. There is no assurance that the value, if any, that may be realized will be at or near the value estimated by the model. No value will be realized by the optioneesC.W.

Restricted Stock. Restricted Stock shall confer upon the Participant the right to receive Shares subject to such restrictions on transferability and other restrictions as the Committee may impose (including, without limitation, forfeiture if such restrictions are not satisfied, limitations on the right to vote and limitations on the right to receive dividends), which restrictions may expire at such times and under such circumstances as the Committee shall determine. 6.04. Options. An Option shall confer upon the Participant the right to purchase Shares, other Awards or property, subject to the following terms and conditions: (a) Exercise Price. The exercise price per share purchasable under an Option shall not be less than the Fair Market Value of a Share on the date of grant of such Option. (b) Time and Method of Exercise. The Committee shall determine the time during which an Option may be exercised in whole or in part, the methods by which the exercise price may be paid and the methods by which Shares will be delivered to Participants. Options shall expire not later than ten years after the date of grant. (c) Terms Applicable to Incentive Stock Options. The terms of any Incentive Stock Option granted under the Plan shall comply in all respects with the provisions of Section 422 of the Code which, among other limitations, provides that the aggregate Fair Market Value (determined at the time the Option is granted) of Shares for which Incentive Stock Options are exercisable for the first time by a Participant during any calendar year shall A - 4 not exceed $100,000.

Anything in the Plan to the contrary notwithstanding, no term of the Plan relating to Incentive Stock Options, other than Section 9, shall be applied, interpreted, amended or altered, nor shall any discretion or authority granted under the Plan be exercised, so as to disqualify the Plan under Section 422 of the Code or, without the consent of the Participant affected, to disqualify any Incentive Stock Option under such Section 422. (d) Limitation on Re-Pricing and Replacement. No Option shall provide by its terms for the re-setting of its exercise price, or for its replacement, in whole or in part, upon its exercise or expiration; provided that the foregoing shall not limit the authority of the Committee to grant additional Options in any such event or circumstances. (e) Cash Out by Committee. Upon receipt of written notice of exercise, the Committee may elect to cash out all or part of the portion of the Shares for which an Option is being exercised by paying the optionee an amount, in cash or Shares, equal to the excess of the Fair Market Value of Shares over the option price times the number of Shares for which the Option is being exercised on the effective date of such cash-out. (f) Change in Control Cash-Out Right. Notwithstanding any other provision of the Plan, during the 60-day period from and after a Change in Control (the "Exercise Period"), unless the Committee shall determine otherwise at the time of grant, a holder of an Option to purchase Shares shall have the right, whether or not the Option is fully exercisable and in lieu of the payment of the exercise price for the Shares being purchased under the Option and by giving notice to the Corporation, to elect (within the Exercise Period) to surrender all or part of the Option to the Corporation and to receive cash, within 30 days of such notice, in an amount equal to the amount by which the Change in Control Price per Share on the date of such election shall exceed the exercise price per Share under the Option (the "Spread") multiplied by the number of Shares granted under the Option as to which the right granted under this Section 6.04(f) shall have been exercised. Notwithstanding the foregoing, if any right granted pursuant to this Section 6.04(f) would make a Change in Control transaction ineligible for pooling-of-interests accounting under APB No. 16 that but for the nature of such grant would otherwise be eligible for such accounting treatment, the Committee shall have the ability to substitute for the cash payable pursuant to such right Shares or other securities with a Fair Market Value equal to the cash that would otherwise be payable hereunder. 6.05. Stock Appreciation Rights. A Stock Appreciation Right shall confer upon the Participant a right to receive the excess of (a) the Fair A - 5 Market Value of one Share on the date of exercise (or, except in the case of a Stock Appreciation Right related to an Incentive Stock Option, the Fair Market Value of one Share at any time during a specified period before or after the date of exercise) over (b) the grant price of the Stock Appreciation Right, which shall be not less than the Fair Market Value of one Share on the date of grant. A Stock Appreciation Right may be granted as a Limited Stock Appreciation Right which may be exercised only upon the occurrence of a Change in Control. Stock Appreciation Rights shall expire not later than ten years after the date of grant. 6.06. Dividend Equivalents. A Dividend Equivalent shall confer upon the Participant a right to receive cash, Shares, other Awards or other property equal in value to dividends paid with respect to a specified number of Shares. 6.07. Other Stock-Based Awards. The Committee is authorized to grant to Participants such other Awards that are denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, Shares, as deemed by the Committee to be consistent with the purpose of the Plan. Section 7. Certain Provisions Applicable to Awards. 7.01. Qualified Performance-Based Awards. The Committee may, at or prior to the time of grant, designate Performance Units or Restricted Stock, or any other Award, as a Qualified Performance-Based Award, in which event it shall take such action with respect to such Award and the terms thereof (including the imposition of additional requirements not otherwise required by the terms of the Plan), and the provisions of the Plan or any Award Agreement shall be construed or deemed amended, as shall be necessary to cause such Award to qualify for the Section 162(m) Exemption. 7.02. Term of Awards. The term of each Award shall be for such period as shall be determined by the Committee subject to the requirements of the Plan. 7.03. Forms of Payment. Subject to the terms of the Plan and any applicable Award Agreement, (a) payments to be made by the Corporation, a Subsidiary or Affiliate with respect to Awards are to be made in such forms as the Committee shall determine; and (b) the timing, method, amount and nature of payments to be made by Participants with respect to Awards (including, if permitted by the Committee, by means of tendering Shares or Awards) shall be determined by the Committee. 7.04. Termination of Employment. If the employment of a Participant terminates, all unexercised, deferred and unpaid Awards shall be cancelled immediately, unless the Award Agreement provides otherwise or unless the A - 6 Committee shall provide otherwise in connection with such termination, including, without limitation, in the case of termination pursuant to retirement, resignation, death or disability of a Participant. Section 8. General Restrictions Applicable to Awards. 8.01. Restrictions Under Rule 16b-3. It is the intent of the Corporation that any Award granted to a person who is subject to Section 16 of the Exchange Act qualify for exemption under Rule 16b-3. Accordingly, if any provision of the Plan or any Award Agreement would cause such an Award to fail to qualify for such exemption, such provision shall be construed or deemed amended to the extent necessary to enable such Award to qualify for such exemption. 8.02. Limits on Transfer of Awards; Beneficiaries. No Award may be assigned or transferred by a Participant otherwise than by will or the laws of descent and distribution, or payable to or exercisable by anyone other than the Participant to whom it was granted, and no right or interest of a Participant in any Award may be pledged, encumbered or hypothecated to or in favor of any party, or shall be subject to any lien, obligation or liability of a Participant to any party; provided, however, that (a) a Participant may, in the manner established by the Committee, designate a beneficiary or beneficiaries to exercise the rights of the Participant, and to receive any distribution with respect to any Award, upon the death or disability of the Participant, (b) the Committee may provide in any Award or the related Award Agreement that an Award (other than an Incentive Stock Option) may be assigned, transferred, exercisable by another person or pledged, encumbered or hypothecated, subject to the applicable requirements of the Code, and (c) transfers of Awards may be made to the Corporation, a Subsidiary or an Affiliate to the extent permitted under the terms of the Plan. A beneficiary, guardian, legal representative or other person claiming any rights under the Plan from or through any Participant shall be subject to all terms and conditions applicable to such Participant, except to the extent the Plan and such Award Agreement otherwise provide with respect to such person, and to any additional restrictions deemed necessary or appropriate by the Committee. 8.03. Share Certificates. All certificates for Shares delivered under the Plan pursuant to an Award or the exercise thereof shall be subject to such stop-transfer orders and other restrictions as the Committee may deem advisable under applicable federal or state laws, rules and regulations and the rules of any national securities exchange on which Shares are listed. The Committee may cause a legend or legends to be placed on any such certificates to make appropriate reference to such restrictions or any other restrictions that may be applicable to Shares. In addition, during any period in which Awards or Shares are subject to restrictions, or during any period A - 7 during which delivery or receipt of an Award or Shares has been deferred by the Committee or a Participant, the Committee may require the Participant to enter into an agreement providing that certificates representing Shares issued or issuable pursuant to an Award shall remain in the physical custody of the Corporation or such other person as the Committee may designate. If certificates representing Restricted Stock are registered in the name of the Participant, such certificates shall bear an appropriate legend referring to the terms, conditions and restrictions applicable to such Restricted Stock, the Corporation shall retain physical possession of the certificates and the Participant shall deliver a stock power to the Corporation, endorsed in blank, relating to the Restricted Stock. Section 9. Change in Control. (a) Impact of Event. Notwithstanding any other provision of the Plan to the contrary, in the event of a Change in Control: (i) any Options and Stock Appreciation Rights outstanding as of the date such Change in Control is determined to have occurred, and which are not then exercisable and vested, shall become fully exercisable and vested to the full extent of the original grant; (ii) the restrictions and deferral limitations applicable to any Restricted Stock shall lapse, and such Restricted Stock shall become free of all restrictions and become fully vested and transferable to the full extent of the original grant; and (iii) all Performance Units shall be considered to be earned and payable in full, and any deferral or other restriction shall lapse and such Performance Units shall be settled in cash or other securities as promptly as is practicable. (b) Definition of Change in Control. For purposes of the Plan, a "Change in Control" shall mean the happening of any of the following events: (i) an acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a "Person") of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of either (1) the then outstanding shares of common stock of the Corporation (the "Outstanding Corporation Common Stock") or (2) the combined voting power of the then outstanding voting securities of the Corporation entitled to vote generally in the election of directors (the "Outstanding Corporation Voting Securities"); excluding, however, the following: (1) any acquisition directly from the Corporation, other than an acquisition by virtue of the exercise of a conversion privilege unless the security being so converted was itself acquired directly from the Corporation, (2) any acquisition by the Corporation, (3) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Corporation or any corporation controlled by the Corporation or (4) any A - 8 acquisition by any corporation pursuant to a transaction which complies with clauses (1), (2) and (3) of subsection (iii) of this Section 9(b); or (ii) a change in the composition of the Board such that the individuals who, as of the effective date of the Plan, constitute the Board (such Board shall be hereinafter referred to as the "Incumbent Board") cease for any reason to constitute at least a majority of the Board; provided, however, for purposes of this Section 9(b), that any individual who becomes a member of the Board subsequent to the effective date of the Plan, whose election, or nomination for election by the Corporation's shareholders, was approved by a vote of at least a majority of those individuals who are members of the Board and who are also members of the Incumbent Board (or deemed to be such pursuant to this proviso) shall be considered as though such individual were a member of the Incumbent Board; but, provided further, that any such individual whose initial assumption of office occurs as a result of either an actual or threatened election contest (as such terms are used in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act) or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board shall not be so considered as a member of the Incumbent Board; or (iii) the approval by the shareholders of the Corporation of a reorganization, merger or consolidation or sale or other disposition of all or substantially all of the assets of the Corporation ("Corporate Transaction") or, if consummation of such Corporate Transaction is subject, at the time of such approval by shareholders, to the consent of any government or governmental agency, obtaining of such consent (either explicitly or implicitly by consummation); excluding however, such a Corporate Transaction pursuant to which (1) all or substantially all of the individuals and entities who are the beneficial owners, respectively, of the Outstanding Corporation Common Stock and Outstanding Corporation Voting Securities immediately prior to such Corporate Transaction will beneficially own, directly or indirectly, more than 60% of, respectively, the outstanding shares of common stock, and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the corporation resulting from such Corporate Transaction (including, without limitation, a corporation which as a result of such transaction owns the Corporation or all or substantially all of the Corporation's assets either directly or through one or more subsidiaries) in substantially the same proportions as their ownership, immediately prior to such Corporate Transaction, of the Outstanding Corporation Common Stock and Outstanding Corporation Voting Securities, as the case may be, (2) no Person (other than the Corporation, any employee benefit plan (or related trust) of the Corporation or such corporation resulting from such Corporate A - 9 Transaction) will beneficially own, directly or indirectly, 20% or more of, respectively, the outstanding shares of common stock of the corporation resulting from such Corporate Transaction or the combined voting power of the outstanding voting securities of such corporation entitled to vote generally in the election of directors except to the extent that such ownership existed prior to the Corporate Transaction, and (3) individuals who were members of the Incumbent Board will constitute at least a majority of the members of the board of directors of the corporation resulting from such Corporate Transaction; or (iv) the approval by the stockholders of the Corporation of a complete liquidation or dissolution of the Corporation. (c) Change in Control Price. For purposes of the Plan, "Change in Control Price" means the higher of (i) the highest reported sales price, regular way, of a Share in any transaction reported on the New York Stock Exchange Composite Tape or other national exchange on which such Shares are listed or on NASDAQ during the 60-day period prior to and including the date of a Change in Control or (ii) if the Change in Control is the result of a tender or exchange offer or a Corporate Transaction, the highest price per Share paid in such tender or exchange offer or Corporate Transaction; provided, however, that in the case of Incentive Stock Options and Stock Appreciation Rights relating to Incentive Stock Options, the Change in Control Price shall be in all cases the Fair Market Value of the Shares on the date such Incentive Stock Option or Stock Appreciation Right (or related cash-out right under Section 6.04(f)) is exercised. To the extent that the consideration paid in any such transaction described above consists all or in part of securities or other noncash consideration, the value of such securities or other noncash consideration shall be determined in the sole discretion of the Board. Section 10. Adjustment Provisions. In the event that the Committee shall determine that any dividend or other distribution (whether in the form of cash, Shares or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, spin-off, combination, repurchase or share exchange, or other similar corporate transaction or event, affects the Shares such that an adjustment is determined by the Committee to be appropriate in order to prevent dilution or enlargement of the rights of Participants under the Plan, then the Committee shall, in such manner as it may deem equitable, make any adjustments it deems appropriate (including, without limitation, adjustments to the share limitations contained in Section 4 and to the terms of then-outstanding Awards). In addition, the Committee is authorized to make such adjustments as it deems appropriate in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events A - 10 (including, without limitation, events described in the preceding sentence) affecting the Corporation or any Subsidiary or Affiliate or the financial statements of the Corporation or any Subsidiary or Affiliate, or in response to changes in applicable laws, regulations or accounting principles. Section 11. Changes to the Plan and Awards. 11.01. Changes to the Plan. The Board may amend, alter, suspend, discontinue or terminate the Plan without the consent of shareholders or Participants, except as is required by any federal or state law or regulation or the rules of any stock exchange on which the Shares may be listed, or if the Board in its discretion determines that obtaining such shareholder approval is for any reason advisable; provided, however, that, without the consent of an affected Participant, no amendment, alteration, suspension, discontinuation or termination of the Plan may impair the rights of such Participant under any Award theretofore granted to such Participant. 11.02. Changes to Awards. The Committee may waive any conditions or rights under, or amend, alter, accelerate, suspend, discontinue or terminate, any Award theretofore granted and any Award Agreement relating thereto; provided, however, that, without the consent of an affected Participant, no such amendment, alteration, suspension, discontinuation or termination of any Award may impair the rights of such Participant under such Award; and provided, further, that no amendment or alteration may be effective with respect to a Qualified Performance-Based Award if and to the extent it would cause such Award to cease to qualify for the Section 162(m) Exemption. Section 12. General Provisions. 12.01. No Rights to Awards. No Participant, officer, employee or director shall have any claim to be granted any Award under the Plan, and there is no obligation for uniformity of treatment of Participants or any other persons. 12.02. No Shareholder Rights. No Award shall confer on any Participant any of the rights of a shareholder of the Corporation unless and until Shares are duly issued or transferred to the Participant in accordance with the terms of the Award. 12.03. Dividends. The recipient of any Award may, if so determined by the Committee, be entitled to receive on a current or deferred basis, dividends or Dividend Equivalents, with respect to the number of Shares covered by the Award. 12.04. Tax Withholding. The Corporation or any Subsidiary or Affiliate is authorized to withhold from any award granted, any payment relating to an Award under the Plan (including from a distribution of Shares) or any payroll or other payment to a Participant, amounts of withholding and A - 11 other taxes due with respect thereto, its xercise or any payment thereunder, and to take such other action as the Committee may deem necessary or advisable to enable the Corporation and Participants to satisfy obligations for the payment of withholding taxes and other tax liabilities relating to any Award. This authority shall include authority to withhold or receive Shares or other property and to make cash payments in respect thereof in satisfaction of a Participant's tax obligations. 12.05. No Right to Employment. Nothing contained in the Plan or any Award Agreement shall confer, and no grant of an Award shall be construed as conferring, upon any employee any right to continue in the employ of the Corporation or any Subsidiary or Affiliate or to interfere in any way with the right of the Corporation or any Subsidiary or Affiliate to terminate the employee's employment at any time or increase or decrease the employee's compensation from the rate in existence at the time of granting of an Award. 12.06. Unfunded Status of Awards. The Plan is intended to constitute an "unfunded" plan for incentive and deferred compensation. Nothing contained in the Plan, any Award Agreement or any Award shall give any such Participant any rights that are greater than those of an unsecured general creditor of the Corporation. 12.07. Other Compensatory Arrangements. The Corporation or any Subsidiary or Affiliate shall be permitted to adopt other or additional compensation arrangements (which may include arrangements which relate to Awards), and such arrangements may be either generally applicable or applicable only in specific cases. 12.08. Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan or any Award. The Committee shall determine whether cash, other Awards or other property shall be issued or paid in lieu of fractional Shares or whether such fractional Shares or any rights thereto shall be forfeited or otherwise eliminated. 12.09. Governing Law. The validity, construction and effect of the Plan, any rules and regulations relating to the Plan, any action taken pursuant to the Plan and any Award Agreement shall be governed by the laws of the State of Missouri, without giving effect to principles of conflicts of laws, and applicable federal law. 12.10. Tax Offset Bonuses. At the time an Award is made under the Plan or at any time thereafter, the Committee may grant to the Participant receiving such Award the right to receive a cash payment in an amount specified by the Committee, to be paid at such time or times (if ever) as the Award results in compensation income to the Participant, for the purpose of assisting the Participant to pay the resulting taxes, all as determined by the A - 12 Committee and on such other terms and conditions as the Committee shall determine. Section 13. Laws and Regulations. The Plan, the granting and exercising of Awards thereunder and the other obligations of the Corporation under the Plan shall be subject to all applicable federal and state laws, rules and regulations and to such approvals by any regulatory or governmental agency as may be required. The Corporation, in its discretion, may postpone the granting and exercising of Awards, the issuance or delivery of Shares under any Award or any other action permitted under the Plan to permit the Corporation, with reasonable diligence, to complete any stock exchange listing or registration or qualification of such Shares or other required action under any federal or state law, rule or regulation and may require any participant to make such representations and furnish such information as it may consider appropriate in connection with the issuance of delivery of Shares in compliance with applicable laws, rules and regulations. The Corporation shall not be obligated by virtue of any provision of the Plan to recognize the exercise of any Award or to otherwise sell or issue Shares in violation of any such laws, rules, or regulations; and any postponement of the exercise or settlement of any Award under this provision shall not extend the term of such Award, and neither the Corporation nor its directors or officers shall have any obligation or liability to any Participant with respect to any Award (or stock issuable thereunder) that shall lapse because of such postponement. Section 14. Effective Date. The Plan shall become effective on April 1, 1998; provided that the effectiveness of the Plan shall be subject to the approval of the Plan by the affirmative vote of the holders of a majority of the Shares present or represented and entitled to vote at the next following meeting of the Corporation's shareholders. The Committee shall have the authority to grant Awards prior to such approval; provided that the effectiveness of such Awards shall be subject to such shareholder approval of the Plan. The Plan shall terminate ten years after its effective date, subject to earlier termination by the Board pursuant to Section 11, after which no Awards may be made under the Plan, but any such termination shall not affect Awards then outstanding or the authority of the Committee to continue to administer the Plan.
