        indicated that the downgrade of the registrants was prompted by the passage
        of
        legislation in the Illinois Senate on April 20, 2007 that would roll back
        electric rates to pre-January 2, 2007 levels and freeze rates at those levels
        for at least one year, as well as require the refunding of revenues collected
        since January 1, 2007 due to rate increases. S&amp;P noted that, if such
        legislation is signed into law, it would result in a significant revenue
        shortfall and materially affect the liquidity of the Ameren Illinois utilities.
        S&amp;P further stated that the investment grade ratings of Ameren, UE, and
        Genco assume that if the Ameren Illinois utilities experience &#8220;significant
        stand-alone stress,&#8221; Ameren will not provide material support to the Ameren
        Illinois utilities. S&amp;P indicated that while a complete rate rollback and
        freeze would be harmful to Ameren&#8217;s consolidated financial profile, it expects
        that in such event damage to Ameren, UE, and Genco would be contained and
        that
        S&amp;P would likely keep Ameren&#8217;s, UE&#8217;s, and Genco&#8217;s corporate credit ratings
        investment grade. </font></div>

        ratings. The downgrades may also increase the cost of borrowing and costs
        of
        fuel, power and gas supply, among other things, resulting in a negative impact
        on earnings. The registrants may also be required to post collateral or other

        April
        24, 2007, Moody's Investors Service, Inc. ("Moody's") stated&#160;its view that
        the passage of rate freeze legislation by the Illinois Senate&#160;was a
        negative development although it will not have an immediate impact on the
        credit
        ratings of Ameren or the Ameren Illinois utilities.&#160; Moody's also stated
        that any progress toward passage of the legislation by the Illinois House
        could
        result in a ratings downgrade of the Ameren Illinois utilities.&#160;
Further,&#160; Moody's said that enactment into law of such legislation could
        result in multi-notch downgrades of the ratings of the Ameren Illinois utilities
        well into speculative grade due to concerns about the impact on the financial
        performance of the Ameren Illinois utilities.</font></div>

A
                  credit rating is not a recommendation to buy, sell or hold securities.
                  It
                  should be evaluated independently of any other rating. Ratings
                  are subject
                  to revision or withdrawal at any time by the rating
                  organization.
S&P
        indicated that the ratings of all of the registrants remain under review
        for
        possible further downgrade.
S&P
        indicated that the downgrade of the registrants was prompted by the passage
        of
        legislation in the Illinois Senate on April 20, 2007 that would roll back
        electric rates to pre-January 2, 2007 levels and freeze rates at those levels
        for at least one year, as well as require the refunding of revenues collected
        since January 1, 2007 due to rate increases. S&P noted that, if such
        legislation is signed into law, it would result in a significant revenue
        shortfall and materially affect the liquidity of the Ameren Illinois utilities.
        S&P further stated that the investment grade ratings of Ameren, UE, and
        Genco assume that if the Ameren Illinois utilities experience "significant
        stand-alone stress," Ameren will not provide material support to the Ameren
        Illinois utilities. S&P indicated that while a complete rate rollback and
        freeze would be harmful to Ameren's consolidated financial profile, it expects
        that in such event damage to Ameren, UE, and Genco would be contained and
        that
        S&P would likely keep Ameren's, UE's, and Genco's corporate credit ratings
        investment grade.
The
        registrants expect that they may be faced with reduced access to capital
        as a
        result of the downgrades by S&P of the registrants' corporate credit
        ratings. The downgrades may also increase the cost of borrowing and costs
        of
        fuel, power and gas supply, among other things, resulting in a negative impact
        on earnings. The registrants may also be required to post collateral or other
        assurances for certain trade obligations. Suppliers may also request prepayment
        for products and services.
On
        April
        24, 2007, Moody's Investors Service, Inc. ("Moody's") stated its view that
        the passage of rate freeze legislation by the Illinois Senate was a
        negative development although it will not have an immediate impact on the
        credit
        ratings of Ameren or the Ameren Illinois utilities.  Moody's also stated
        that any progress toward passage of the legislation by the Illinois House
        could
        result in a ratings downgrade of the Ameren Illinois utilities. 
Further,  Moody's said that enactment into law of such legislation could
        result in multi-notch downgrades of the ratings of the Ameren Illinois utilities
        well into speculative grade due to concerns about the impact on the financial
        performance of the Ameren Illinois utilities.

This
        combined Form 8-K is being filed separately by Ameren, UE, CIPS, Genco, CILCORP,
        CILCO and IP. Information contained herein relating to any individual registrant

FORWARD-LOOKING
        STATEMENTS
Statements
        in this report not based on historical facts are considered "forward-looking"
and, accordingly, involve risks and uncertainties that could cause actual
        results to differ materially from those discussed. Although such forward-looking
        statements have been made in good faith and are based on reasonable assumptions,
        there is no
assurance
        that the expected results will be achieved. These statements include (without
        limitation) statements as to future expectations, beliefs, plans, strategies,
        objectives, events, conditions, and financial performance. In connection
        with
        the "safe harbor" provisions of the Private Securities Litigation Reform Act of
        1995, we 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 our other filings with the Securities and Exchange Commission, could cause
        actual results to differ materially from management expectations suggested
        in
        such forward-looking statements:
·
regulatory
                or legislative actions, including changes in regulatory policies
                and
                ratemaking determinations, such as the outcome of CIPS, CILCO and
                IP rate
                rehearing proceedings, or the enactment of legislation reducing electric
                rates to 2006 levels and freezing electric rates at such levels or
                similar
                actions that impair the full and timely recovery of costs in
                Illinois;
·
the
                success of any legal efforts or negotiations with
                stakeholders;
·
changes
                in laws and other governmental actions;
·
disruptions
                of the capital markets or other events that make 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;
·
the
                inability of our counterparties and affiliates to meet their obligations
                with respect to contracts and financial instruments;
                and
·
legal
                and administrative proceedings.
Given
        these uncertainties, undue reliance should not be placed on these
        forward-looking statements. Except to the extent required by the federal
        securities laws, we undertake no obligation to update or revise publicly
        any
        forward-looking statements to reflect new information or future
        events.
