        for the fiscal year ended December 31, 2005, for a discussion of the joint
        dispatch agreement. The joint dispatch agreement as last amended and restated
        effective January 10, 2006 (filed as Exhibit 10.1 to the Current Report on
        Form
        8-K of Ameren, UE, CIPS and Genco dated January 9, 2006) (&#8220;JDA&#8221;), under which UE
        and Genco jointly dispatch electric generation, provides each affiliate the
        option to serve its load requirements from its own generation first and then
        to
        allow access to any available remaining generation to its affiliate at
        incremental cost. Any excess generation not used by UE or Genco to serve
        load
        requirements is sold to third parties on a short-term basis. Under the
        provisions of the JDA, the margins from third party sales are allocated between
        UE and Genco based on generation output. CIPS is no longer an active participant
        under the JDA due to the transfer of its power plants to Genco in 2000. The
        JDA
        established no specific termination date for the agreement but provided any
        party the right to terminate it on one year&#8217;s notice. The JDA may be terminated
        earlier by mutual consent of the parties. </font></div>

          cost. Since UE was prepared to immediately provide Genco with one year
          notice of
          termination, Genco believes the potential benefit it could receive from
          being
          able to call upon UE&#8217;s generation through June 2007 is outweighed by, among
          other things, the negative consequences associated with the continued existence
          of the JDA past December 31, 2006. In particular, Genco believes that the
          JDA is
          no longer necessary or effective in dispatching Genco&#8217;s generation jointly with
          that of UE due to changes in the marketplace for the sale of electricity,
          including the MISO Day Two Energy Market, and the centralized dispatching
          of
          generation by MISO.&#160; Additionally, the JDA is based on a combined control
          area for the UE and CIPS transmission facilities located in Missouri and
          Illinois, respectively.&#160; This combined control area creates operational
          inefficiencies for Genco to effectively participate through Ameren Energy
          Marketing Company (&#8220;Marketing Company&#8221;) in the Illinois power procurement
          auction for power beginning January 1, 2007.&#160; In conjunction with
          terminating the JDA, Ameren&#8217;s transmission-owning entities intend to restructure
          their control areas so as to have one control area in Missouri for UE&#8217;s
          transmission facilities and one in Illinois for the transmission facilities
          of
          CIPS, CILCO and IP. </font></div>

          a
          result of the termination of the JDA on December 31, 2006, UE and Genco
          will no
          longer have the obligation to provide power to each other. In 2005, Genco
          received from UE under the JDA net transfers of 8.7 million megawatthours
          of
          power at an average price of $18 per megawatthour and generated 14.2 million
          megawatthours of power from its plants at an average cost of approximately
          $18
          per megawatthour. This power, along with 1.2 million megawatthours purchased
          from Electric Energy, Inc. (&#8220;EEI&#8221;), which is 40% owned by UE and 40% owned by
          Ameren Energy Development Company, was used in 2005 to supply CIPS&#8217; load and
          other wholesale and retail customers at an average selling price of $35
          per
          megawatthour. In 2005, Genco also sold 3.3 million net megawatthours of
          power in
          the interchange market at $47 per megawatthour. Upon termination of the
          JDA,
          Genco will no longer receive the margins on sales that were supplied with
          power
          from UE. However, Genco will still have access to its own generation and
          expects
          to be able to sell this power at higher average prices than this power
          was sold
          for in 2005 because of the expiration of its power supply contract with
          CIPS and
          the expiration of contracts to supply other wholesale and retail customers
          on or
          before December 31, 2006. Genco currently expects to generate approximately
          17.5
          million megawatthours of power in 2007. By 2007, only 5.2 million megawatthours
          of power covered by wholesale and retail electric power supply agreements
          that
          were in effect in 2005 will remain outstanding. These agreements have an
          average
          embedded selling price of $36 per megawatthour. All other power supply
          agreements in effect in 2005 will expire by the end of 2006 and any available
          generation will be sold at prevailing market prices. Genco and AmerenEnergy
          Resources Generating Company (&#8220;AERG&#8221;) (a subsidiary of CILCO) through their
          affiliate Marketing Company and UE will have the opportunity to participate
          in
          the Illinois power procurement auction for 2007. However, they would be
          subject
          to a limitation of 35% of CIPS&#8217;, CILCO&#8217;s and IP&#8217;s annual load, or about 13
          million megawatthours, which is an auction restriction imposed on any single
          supplier providing power to CIPS, CILCO and IP through the auction. Ameren
          affiliated companies will be considered one supplier for purposes of this
          limitation.</font></div>

          2007, Ameren&#8217;s earnings are also expected to be impacted by the expiration on
          December 31, 2006, of the contract for AERG to supply CILCO with power.
          AERG
          currently expects to generate approximately 7 million megawatthours of
          power in
          2007 compared to 5.9 million megawatthours of power that was generated
          in 2005
          at an average cost of approximately $15 per megawatthour. In 2005, this
          power
          was sold principally to CILCO at an average price of $32 per megawatthour.
          In
          addition, AERG sold 1 million net megawatthours of power in the interchange
          market at $38 per megawatthour in 2005. In 2007, all of AERG&#8217;s power will be
          sold at prevailing market prices. On December 31, 2005, a power supply
          agreement
          with EEI for UE, CIPS (whose entitlement was resold to Marketing Company)
          and IP
          expired. Power supplied under the agreement by EEI to UE, Marketing Company
          and
          IP was priced at EEI&#8217;s cost-based rates. Power previously supplied under this
          agreement to UE, Marketing Company and IP is being sold at market prices
          in
          2006, which are above EEI&#8217;s cost-based rates and will continue to be sold at
          market prices in 2007. However, in 2006, UE, Genco (which supplies Marketing
          Company) and IP are replacing power previously received from EEI either
          through
          the use of their own higher-cost generation or higher-cost power purchases.
          In
          2005, EEI generated 7.9 million megawatthours of power. UE, CIPS (which

ITEM
        1.02
        Termination of a Material Definitive Agreement.
Reference
        is made to Note 2 - Rate and Regulatory Matters and Note 7 - Related Party
        Transactions to the financial statements under Part I, Item 1, Outlook under
        Part I, Item 2. Management's Discussion and Analysis of Financial Condition and
        Results of Operations, and Risk Factors under Part II, Item 1A in the Form
        10-Q
        for the quarterly period ended March 31, 2006, of registrant Ameren Corporation
        ("Ameren") and its registrant subsidiaries, 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., Central Illinois Light Company, doing business as AmerenCILCO
        ("CILCO") and Illinois Power Company, doing business as AmerenIP ("IP")
        (collectively, the "registrants"), for a discussion of the joint dispatch
        agreement among UE, CIPS and Genco and the Illinois power procurement auction.
        Reference is also made to Note 14 - Related Party Transactions to the financial
        statements under Part II, Item 8 in the registrants' Annual Report on Form 10-K
        for the fiscal year ended December 31, 2005, for a discussion of the joint
        dispatch agreement. The joint dispatch agreement as last amended and restated
        effective January 10, 2006 (filed as Exhibit 10.1 to the Current Report on
        Form
        8-K of Ameren, UE, CIPS and Genco dated January 9, 2006) ("JDA"), under which UE
        and Genco jointly dispatch electric generation, provides each affiliate the
        option to serve its load requirements from its own generation first and then
        to
        allow access to any available remaining generation to its affiliate at
        incremental cost. Any excess generation not used by UE or Genco to serve
        load
        requirements is sold to third parties on a short-term basis. Under the
        provisions of the JDA, the margins from third party sales are allocated between
        UE and Genco based on generation output. CIPS is no longer an active participant
        under the JDA due to the transfer of its power plants to Genco in 2000. The
        JDA
        established no specific termination date for the agreement but provided any
        party the right to terminate it on one year's notice. The JDA may be terminated
        earlier by mutual consent of the parties.
On
        July
        7, 2006, UE, CIPS and Genco mutually consented to waive the one year termination
        notice requirement and agreed to terminate the JDA on December 31, 2006.
        This
        action with respect to the JDA will require acceptance by the Federal Energy
        Regulatory Commission ("FERC").
The
        benefits of the JDA to UE and Genco have changed recently due to the emergence
        of transparent wholesale markets, the dispatching of generation being conducted
        by the Midwest Independent Transmission System Operator, Inc. ("MISO"), and
        changes to the Illinois regulatory framework, among other things. As a result,
        UE believes the benefit it will receive from retaining the power it was
        transferring under the JDA to Genco at incremental cost will exceed the benefit
        it would have received from being able to call upon Genco's generation under the
        JDA at
-2-
incremental
          cost. Since UE was prepared to immediately provide Genco with one year
          notice of
          termination, Genco believes the potential benefit it could receive from
          being
          able to call upon UE's generation through June 2007 is outweighed by, among
          other things, the negative consequences associated with the continued existence
          of the JDA past December 31, 2006. In particular, Genco believes that the
          JDA is
          no longer necessary or effective in dispatching Genco's generation jointly with
          that of UE due to changes in the marketplace for the sale of electricity,
          including the MISO Day Two Energy Market, and the centralized dispatching
          of
          generation by MISO.  Additionally, the JDA is based on a combined control
          area for the UE and CIPS transmission facilities located in Missouri and
          Illinois, respectively.  This combined control area creates operational
          inefficiencies for Genco to effectively participate through Ameren Energy
          Marketing Company ("Marketing Company") in the Illinois power procurement
          auction for power beginning January 1, 2007.  In conjunction with
          terminating the JDA, Ameren's transmission-owning entities intend to restructure
          their control areas so as to have one control area in Missouri for UE's
          transmission facilities and one in Illinois for the transmission facilities
          of
          CIPS, CILCO and IP.
As
          a
          result of the termination of the JDA on December 31, 2006, UE and Genco
          will no
          longer have the obligation to provide power to each other. In 2005, Genco
          received from UE under the JDA net transfers of 8.7 million megawatthours
          of
          power at an average price of $18 per megawatthour and generated 14.2 million
          megawatthours of power from its plants at an average cost of approximately
          $18
          per megawatthour. This power, along with 1.2 million megawatthours purchased
          from Electric Energy, Inc. ("EEI"), which is 40% owned by UE and 40% owned by
          Ameren Energy Development Company, was used in 2005 to supply CIPS' load and
          other wholesale and retail customers at an average selling price of $35
          per
          megawatthour. In 2005, Genco also sold 3.3 million net megawatthours of
          power in
          the interchange market at $47 per megawatthour. Upon termination of the
          JDA,
          Genco will no longer receive the margins on sales that were supplied with
          power
          from UE. However, Genco will still have access to its own generation and
          expects
          to be able to sell this power at higher average prices than this power
          was sold
          for in 2005 because of the expiration of its power supply contract with
          CIPS and
          the expiration of contracts to supply other wholesale and retail customers
          on or
          before December 31, 2006. Genco currently expects to generate approximately
          17.5
          million megawatthours of power in 2007. By 2007, only 5.2 million megawatthours
          of power covered by wholesale and retail electric power supply agreements
          that
          were in effect in 2005 will remain outstanding. These agreements have an
          average
          embedded selling price of $36 per megawatthour. All other power supply
          agreements in effect in 2005 will expire by the end of 2006 and any available
          generation will be sold at prevailing market prices. Genco and AmerenEnergy
          Resources Generating Company ("AERG") (a subsidiary of CILCO) through their
          affiliate Marketing Company and UE will have the opportunity to participate
          in
          the Illinois power procurement auction for 2007. However, they would be
          subject
          to a limitation of 35% of CIPS', CILCO's and IP's annual load, or about 13
          million megawatthours, which is an auction restriction imposed on any single
          supplier providing power to CIPS, CILCO and IP through the auction. Ameren
          affiliated companies will be considered one supplier for purposes of this
          limitation.
Ameren's
          earnings will be affected by the termination of the JDA when UE's rates are
          adjusted by the Missouri Public Service Commission (MoPSC). As noted in
          the
          press release (Exhibit 99.1 hereto) incorporated by reference under Item
          8.01
          below, UE announced on July 7, 2006, that it had filed a request with the
          MoPSC
          to increase its electric rates by $361 million. UE's requested increase is net
          of the decrease in its revenue requirement resulting from increased margins
          expected to result from the termination of the JDA. UE's proposed rate increase
          is subject to review and approval by the MoPSC.
In
          2007, Ameren's earnings are also expected to be impacted by the expiration on
          December 31, 2006, of the contract for AERG to supply CILCO with power.
          AERG
          currently expects to generate approximately 7 million megawatthours of
          power in
          2007 compared to 5.9 million megawatthours of power that was generated
          in 2005
          at an average cost of approximately $15 per megawatthour. In 2005, this
          power
          was sold principally to CILCO at an average price of $32 per megawatthour.
          In
          addition, AERG sold 1 million net megawatthours of power in the interchange
          market at $38 per megawatthour in 2005. In 2007, all of AERG's power will be
          sold at prevailing market prices. On December 31, 2005, a power supply
          agreement
          with EEI for UE, CIPS (whose entitlement was resold to Marketing Company)
          and IP
          expired. Power supplied under the agreement by EEI to UE, Marketing Company
          and
          IP was priced at EEI's cost-based rates. Power previously supplied under this
          agreement to UE, Marketing Company and IP is being sold at market prices
          in
          2006, which are above EEI's cost-based rates and will continue to be sold at
          market prices in 2007. However, in 2006, UE, Genco (which supplies Marketing
          Company) and IP are replacing power previously received from EEI either
          through
          the use of their own higher-cost generation or higher-cost power purchases.
          In
          2005, EEI generated 7.9 million megawatthours of power. UE, CIPS (which
-3-
resold
          the power to Marketing Company) and IP purchased 3.0 million, 2.0 million
          and
          1.2 million megawatthours, respectively, from EEI at an average price of
          $20 per
          megawatthour. The remaining generation was sold to EEI's minority owner. The
          expiration of this agreement and the resulting decrease in UE's margins and
          increase in its revenue requirement was also reflected in UE's July 7, 2006,
          request to the MoPSC to increase electric rates discussed
          above.
The
        ultimate impact of all of the matters mentioned above on the registrants'
results of operation, financial position, or liquidity cannot be predicted
        at
        this time.

      beliefs, plans, strategies, objectives, events, conditions, and financial
      performance. In connection with the "safe harbor" provi-sions of the Private
      Securities Litigation Reform Act of 1995, the registrants are providing this
      cautionary statement to identify important factors that could cause actual
      results to differ materially from those anticipated. The following factors,
      in
      addition to those discussed elsewhere in this report and in the registrants'
other filings with the SEC, could cause actual results to differ materially
      from
      management expectations suggested in such forward-looking
      statements:
·
regulatory
                actions, including changes in regulatory policies and ratemaking
                determinations;
·
changes
                in laws and other governmental actions, including monetary and fiscal
                policies;
·
the
                effects of increased competition in the future due to, among other
                things,
                deregulation of certain aspects of the registrants' business at both the
                state and federal levels, and the implementation of deregulation,
                such as
                when the current electric rate freeze and current power supply contracts
                expire in Illinois at the end of
                2006;
·
the
                effects of participation in the
                MISO;
·
the
                availability of fuel such as coal, natural gas and enriched uranium
                used
                to produce electricity; the availability of purchased power and natural
                gas for distribution; and the level and volatility of future market
                prices
                for such commodities, including the ability to recover the costs
                for such
                commodities;

·
the
                effectiveness of the registrants' risk management strategies and the use
                of financial and derivative instruments;
·
prices
                for power in the Midwest;
·
business
                and economic conditions, including their impact on interest rates;
·
disruptions
                of the capital markets or other events that make the registrants
                access to
                necessary capital more difficult or
                costly;
·
the
                impact of the adoption of new accounting standards and the application
                of
                appropriate technical accounting rules and guidance;
·
actions
                of credit rating agencies and the effects of such actions;
·
weather
                conditions and other natural phenomena;

                plant construction, installation and performance, including costs
                associated with UE's Taum Sauk pumped-storage hydroelectric plant incident
                and its future operation;
·
operation
                of UE's nuclear power facility, including planned and unplanned outages,
                and decommissioning costs;
·
the
                effects of strategic initiatives, including acquisitions and divestitures;
·
the
                impact of current environmental regulations on utilities and power
                generating companies and the expectation that more stringent requirements
                will be introduced over time, which could have a negative financial
                effect;
·
labor
                disputes and future wage and employee benefits costs, including changes
                in
                returns on benefit plan assets;
·
the
                inability of the registrants' counterparties to meet their obligations
                with respect to contracts and financial instruments;
·
the
                cost and availability of transmission capacity for the energy generated
                by
                the registrants' facilities or required to satisfy energy sales made by
                the registrants;
·
legal
                and administrative proceedings; and
·
acts
                of sabotage, war, terrorism or intentionally disruptive acts.
Given
      these uncertainties, undue reliance should not be placed on these
      forward-looking statements. Except to the extent required by the federal
      securities laws, the registrants undertake no obligation to publicly update
      or
      revise any forward-looking statements to reflect new information or future
      events.
