              and Outlook under Part I, Item 2. Management's Discussion and Analysis of
              Financial Condition and Results of Operations, all in the Form 10-Q
              for the
              quarterly period ended September 30, 2007, of registrant Ameren Corporation
              ("Ameren") and its registrant subsidiary, Union Electric Company, doing business
              as AmerenUE ("UE") (collectively, the "registrants"), for a discussion of the
              December 2005 breach of the upper reservoir at UE's Taum Sauk pumped-storage
              hydroelectric facility and related legal proceedings.
On
              November 28, 2007, UE announced that it had entered into a settlement
              agreement
              with the State of Missouri represented by the Missouri Attorney General,
              the
              Missouri Conservation Commission and the Missouri Department of Natural
              Resources resolving the state of Missouri's lawsuit and claims for damages and
              other relief related to the December 2005 breach of the upper reservoir
              at UE's
              Taum Sauk pumped-storage hydroelectric plant.  In addition, pursuant
              to the settlement agreement, UE is required to replace the breached
              upper
              reservoir at the Taum Sauk pumped-storage hydroelectric plant with
              a new upper
              reservoir, subject to authorization by the Federal Energy Regulatory
              Commission
              ("FERC").  UE's press release with respect to the settlement agreement
              is attached as Exhibit 99.1 and is incorporated herein.
UE
              believes that substantially all damages and liabilities (but not penalties
              such
              as those previously paid to the FERC) caused by the breach, including
              costs
              related to the settlement agreement, the cost of rebuilding the plant,
              and the
              cost of replacement power, up to $8 million annually, will be covered
              by
              insurance.  Under UE's insurance policies, all claims by or against UE
              are subject to review by its insurance carriers.  UE expects the total
              costs for clean-up, damages and liabilities associated with the Taum
              Sauk
              incident, including obligations related to the settlement agreement
              but
              excluding costs to rebuild the facility, to be within the range previously
              disclosed in the Form 10-Q for the quarterly period ended September
              30,
              2007.
As
              part
              of the settlement agreement, UE again agreed that it will not attempt
              to recover
              from ratepayers any in-kind or monetary payments required by the
              settlement.  In particular, UE acknowledged in the settlement
              agreement that it will not attempt to recover from ratepayers in any
              future rate
              increase any in-kind or monetary payments to the state parties required
              by the
              settlement agreement or costs incurred in the reconstruction of the
              new upper
              reservoir (expressly excluding, however, enhancements, costs incurred
              due to
              circumstances or conditions that are currently not reasonably foreseeable
              and
              costs that would have been incurred absent the December 2005 breach
              of the upper
              reservoir at UE's Taum Sauk pumped-storage hydroelectric plant).
The
              settlement agreement will be submitted for approval to the Circuit
              Court of
              Reynolds County, State of Missouri.  The settlement agreement will be
              subject to public review for a period of not less than 30 days and
              no more than
              45 days before it may be approved by the court, and UE's obligations
              pursuant to the settlement agreement are contingent upon the approval
              of the
              settlement agreement by the court.

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;
·
changes
                        in laws and other governmental actions, including monetary
                        and fiscal
                        policies;
·
costs
                        associated with UE's Taum Sauk pumped-storage hydroelectric plant
                        incident, including rebuilding
                        costs;
·
recoverability
                        through insurance of costs associated with the Taum Sauk
                        pumped-storage
                        hydroelectric plant incident; and
·
legal
                        and administrative proceedings, such as a decision by the
                        Circuit Court of
                        Reynolds County, State of Missouri to not approve the settlement
                        agreement.
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.
