                  be eligible to receive awards under the 2006 Omnibus Incentive
                  Compensation Plan, Ameren&#8217;s Human Resources Committee, which will
                  administer this plan, currently expects that approximately 180

                  to
                  shareholder approval of the plan as discussed above. Each performance
                  share unit represents the right to receive a share of Ameren&#8217;s common
                  stock assuming certain performance criteria are achieved. The actual
                  number of performance share units earned will vary from 0 percent
                  to 200
                  percent of the target number of performance share units granted
                  to each
                  Named Executive Officer, based primarily on the Company&#8217;s three-year total

                  units continue to rise and fall in value with Ameren&#8217;s common stock price
                  for two years, at which time the performance share units are paid
                  in
                  Ameren&#8217;s common stock. Dividends on performance share units will accrue
                  and be reinvested into additional performance share units throughout
                  the
                  three-year performance share period. Dividends will be paid on
                  a current
                  basis during the two-year holdback period. Because these performance
                  share
                  units will be earned only if performance goals over performance
                  periods
                  are attained, the amounts, if any, that will be payable to the

                  copy of which was filed as Exhibit 10.2 to Ameren&#8217;s Annual Report on Form
                  10-K for the fiscal year ended December 31, 1998). The Amended
                  and

                  of
                  the predecessor plan but includes the following principal revisions:
                  (i)
                  revises the definition of &#8220;Cause&#8221; to expand the bases which permit the
                  termination of the Named Executive Officer&#8217;s employment after a &#8220;Change of
                  Control&#8221; without requiring Ameren to pay separation benefits under the
                  plan; (ii) revises the definition of &#8220;Good Reason&#8221; to clarify the bases
                  upon which, and impose limitations on, the ability of a Named Executive
                  Officer to terminate his or her employment after a &#8220;Change of Control&#8221; and
                  receive separation benefits under the plan; (iii) revises the definition
                  of &#8220;Change of Control&#8221; (A) to reduce from more than 80 percent to more
                  than 60 percent the minimum required percentage of continuing ownership
                  of
                  outstanding shares of Ameren&#8217;s common stock and outstanding Ameren voting
                  securities following certain business combinations in order not
                  to trigger
                  a &#8220;Change of Control&#8221; and (B) to provide that a &#8220;Change of Control&#8221; will
                  not occur solely because a person acquires more than the permitted
                  amount
                  of the then outstanding shares of Ameren&#8217;s common stock or outstanding
                  Ameren voting securities as a result of the acquisition of shares
                  of
                  common stock or voting securities by Ameren, which has the effect
                  of
                  increasing the proportional number of shares owned by such person;
                  (iv)
                  reduces from three years to two years the period after a &#8220;Change of
                  Control&#8221; during which period if a Named Executive Officer&#8217;s employment is
                  terminated without Cause or by the Named Executive Officer for
                  Good
                  Reason, the Named Executive Officer will be entitled to separation
                  benefits under the plan; (v) provides that if a Named Executive
                  Officer&#8217;s
                  employment is terminated by Ameren without Cause prior to the date
                  of a
                  &#8220;Change of Control&#8221; either (A) at the request of a third party who has
                  indicated an intention or taken steps to effect a &#8220;Change of Control&#8221; or
                  (B) otherwise in connection with or in anticipation of, a &#8220;Change of
                  Control&#8221; which has been threatened or proposed, such termination is deemed
                  to have occurred after a &#8220;Change of Control&#8221; for purposes of the plan,
                  provided a &#8220;Change of Control&#8221; occurs; and (vi) limits Ameren&#8217;s obligation
                  in certain circumstances to reimburse a Named Executive Officer
                  for
                  certain excise taxes on payments received under the
                  plan.</font></div>

      Entry into a Material Definitive Agreement.
On
      February
      10, 2006, the Human Resources Committee of the Board of Directors of Ameren
      Corporation ("Ameren") and the Board of Directors of Ameren took the following
      actions:
·
Authorized
                  the payment of cash bonus awards under the 2005 Ameren Executive
                  Incentive
                  Plan (a copy of which was filed as Exhibit 10.2 to Ameren's combined
                  Current Report on Form 8-K dated February 14, 2005) to the chief
                  executive officer and the four most highly compensated executive
                  officers
                  other than the chief executive officer (collectively, the "Named Executive
                  Officers") of Ameren and its subsidiaries, including Union Electric
                  Company, doing business as AmerenUE ("UE"), Central Illinois Public
                  Service Company, doing business as AmerenCIPS ("CIPS"), Ameren Energy
                  Generating Company ("Genco"), CILCORP Inc. ("CILCORP"), Central Illinois
                  Light Company, doing business as AmerenCILCO ("CILCO") and Illinois Power
                  Company, doing business as AmerenIP ("IP"), collectively referred to as
                  the "Registrants." A table setting forth the cash bonus awards to these
                  Named Executive Officers is attached as Exhibit 10.1 and is incorporated
                  herein by reference.
·
Established
                  the 2006 Ameren Executive Incentive Plan to provide for the payment
                  of
                  cash bonus awards to the Named Executive Officers in 2007 based
                  on 2006
                  corporate results and business line and individual performance.
                  The 2006
                  Ameren Executive Incentive Plan is attached as Exhibit 10.2 and
                  is
                  incorporated herein by reference.
·
Adopted
                    a new incentive compensation plan, called the 2006 Omnibus Incentive
                    Compensation Plan, subject
-
            2
            -
to
                  approval by Ameren's shareholders at its 2006 annual meeting scheduled to
                  be held on May 2, 2006. This plan was adopted to replace, on a
                  prospective basis, the Ameren Long-Term Incentive Plan of 1998
                  (a copy of
                  which was filed as Exhibit 10.1 to Ameren's Annual Report on
                  Form 10-K for the fiscal year ended December 31, 1998) which was
                  previously approved by Ameren shareholders and expires on April
                  1, 2008.
                  The 2006 Omnibus Incentive Compensation Plan, which will be fully
                  described in and appended to Ameren's definitive proxy statement for its
                  2006 annual meeting of shareholders to be filed with the Securities
                  and
                  Exchange Commission ("SEC") pursuant to SEC Regulation 14
A
,
                  retains many of the features of the Ameren Long-Term Incentive
                  Plan of
                  1998 plus provides new features that allow greater flexibility,
                  such as
                  performance units denominated in dollars, restricted stock units,
                  cash-based awards and other stock-based awards. While all employees
                  will
                  be eligible to receive awards under the 2006 Omnibus Incentive
                  Compensation Plan, Ameren's Human Resources Committee, which will
                  administer this plan, currently expects that approximately 180
                  employees,
                  including the Named Executive Officers, will initially participate
                  in the
                  plan. Ameren's Board of Directors currently expects that all
                  non-management directors will also initially participate in the
                  plan. The
                  2006 Omnibus Incentive Compensation Plan is attached as Exhibit
                  10.3 and
                  is incorporated herein by
                  reference.
·
Authorized
                  the issuance pursuant to the 2006 Omnibus Incentive Compensation
                  Plan of
                  performance share units to the Named Executive Officers, subject
                  to
                  shareholder approval of the plan as discussed above. Each performance
                  share unit represents the right to receive a share of Ameren's common
                  stock assuming certain performance criteria are achieved. The actual
                  number of performance share units earned will vary from 0 percent
                  to 200
                  percent of the target number of performance share units granted
                  to each
                  Named Executive Officer, based primarily on the Company's three-year total
                  shareholder return ("TSR") relative to a utility peer group and continued
                  employment during the three-year period. Once earned, performance
                  share
                  units continue to rise and fall in value with Ameren's common stock price
                  for two years, at which time the performance share units are paid
                  in
                  Ameren's common stock. Dividends on performance share units will accrue
                  and be reinvested into additional performance share units throughout
                  the
                  three-year performance share period. Dividends will be paid on
                  a current
                  basis during the two-year holdback period. Because these performance
                  share
                  units will be earned only if performance goals over performance
                  periods
                  are attained, the amounts, if any, that will be payable to the
                  Named
                  Executive Officers pursuant to the performance share unit awards
                  described
                  above are not determinable at this
                  time.
·
The
                  number of performance share units issued to each Named Executive
                  Officer
                  pursuant to the 2006 Omnibus Incentive Compensation Plan, subject
                  to
                  shareholder approval of the plan, is set forth in the table referred
                  to
                  above and attached as Exhibit 10.1. The form of performance share
                  unit
                  award is attached as Exhibit 10.4 and is incorporated herein by
                  reference.
                  The award agreements between Ameren and each of the Named Executive
                  Officers provide that upon the occurrence of a "Change of Control" as
                  defined in the Amended and Restated Ameren Change of Control Severance
                  Plan referred to below (i) if Ameren continues to exist and its
                  common
                  stock is traded on the New York Stock Exchange ("NYSE") or NASDAQ Stock
                  Market ("NASDAQ") (A) voluntary terminations of employment prior to the
                  end of the performance period or terminations for "Cause" (as defined in
                  the Plan referred to below) at any time prior to pay out of shares
                  result
                  in forfeiture of awards, (B) involuntary terminations of employment
                  or
                  terminations for "Good Reason" (as defined in the Plan referred to below)
                  during the performance period do not change the manner in which
                  awards are
                  earned and become vested and such awards will be paid in shares
                  of Ameren
                  common stock on January 1, 2009 or as soon as practicable thereafter
                  and
                  (C) involuntary terminations of employment or terminations for
"Good
                  Reason" after the performance period result in an immediate payment of
                  earned and vested shares of Ameren common stock and (ii) which
                  occurs on
                  or before December 31, 2008, if Ameren ceases to exist or its common
                  stock is no longer traded on the NYSE or NASDAQ, the 2006 Omnibus
                  Incentive Compensation Plan will be terminated and (A) the target
                  number
                  of performance share units together with accrued dividends thereon
                  will be
                  converted into nonqualified deferred compensation which will accrue
                  interest at the prime rate as provided in the award agreement and,
                  assuming continued employment, such amount will vest and be paid
                  out on
                  December 31, 2008, (B) voluntary terminations of employment or
                  terminations for "Cause" result in forfeiture of the amounts described
                  above in (ii)(A) and (C) involuntary terminations of employment
                  or
                  terminations for "Good Reason" result in an immediate payment of the
                  amounts described above in (ii)(A) (except as otherwise provided
                  in the
                  awards). The award agreements provide that if a "Change of Control" occurs
                  after December 31, 2008 and Ameren ceases to exist or its common
                  stock is
                  no longer traded on the NYSE or

Adopted
                  an Amended and Restated Ameren Change of Control Severance Plan
                  effective
                  February 10, 2006, to replace Ameren's Change of Control Severance Plan (a
                  copy of which was filed as Exhibit 10.2 to Ameren's Annual Report on Form
                  10-K for the fiscal year ended December 31, 1998). The Amended
                  and
                  Restated Change of Control Severance Plan retains many of the features
                  of
                  the predecessor plan but includes the following principal revisions:
                  (i)
                  revises the definition of "Cause" to expand the bases which permit the
                  termination of the Named Executive Officer's employment after a "Change of
                  Control" without requiring Ameren to pay separation benefits under the
                  plan; (ii) revises the definition of "Good Reason" to clarify the bases
                  upon which, and impose limitations on, the ability of a Named Executive
                  Officer to terminate his or her employment after a "Change of Control" and
                  receive separation benefits under the plan; (iii) revises the definition
                  of "Change of Control" (A) to reduce from more than 80 percent to more
                  than 60 percent the minimum required percentage of continuing ownership
                  of
                  outstanding shares of Ameren's common stock and outstanding Ameren voting
                  securities following certain business combinations in order not
                  to trigger
                  a "Change of Control" and (B) to provide that a "Change of Control" will
                  not occur solely because a person acquires more than the permitted
                  amount
                  of the then outstanding shares of Ameren's common stock or outstanding
                  Ameren voting securities as a result of the acquisition of shares
                  of
                  common stock or voting securities by Ameren, which has the effect
                  of
                  increasing the proportional number of shares owned by such person;
                  (iv)
                  reduces from three years to two years the period after a "Change of
                  Control" during which period if a Named Executive Officer's employment is
                  terminated without Cause or by the Named Executive Officer for
                  Good
                  Reason, the Named Executive Officer will be entitled to separation
                  benefits under the plan; (v) provides that if a Named Executive
                  Officer's
                  employment is terminated by Ameren without Cause prior to the date
                  of a
                  "Change of Control" either (A) at the request of a third party who has
                  indicated an intention or taken steps to effect a "Change of Control" or
                  (B) otherwise in connection with or in anticipation of, a "Change of
                  Control" which has been threatened or proposed, such termination is deemed
                  to have occurred after a "Change of Control" for purposes of the plan,
                  provided a "Change of Control" occurs; and (vi) limits Ameren's obligation
                  in certain circumstances to reimburse a Named Executive Officer
                  for
                  certain excise taxes on payments received under the
                  plan.
The
        Amended and Restated Ameren Change of Control Severance Plan, is attached
        as
        Exhibit 10.5 and is
incorporated
        herein by reference.

                  Long-Term
                  Incentive Plan of 1998 (referred to above) to reflect the definition
                  of
                  "Change in Control" established by the Amended and Restated Ameren Change
                  of Control Severance Plan (referred to above). The First Amendment
                  to the
                  Ameren Long-Term Incentive Plan of 1998 is attached as Exhibit
                  10.6 and is

                  purposes from age 65 to age 62 to facilitate the transition from
                  the
                  Long-Term Incentive Plan of 1998, as amended, to the 2006 Omnibus
                  Incentive Compensation Plan discussed
