&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;These
amounts have been updated to reflect EME's financing activities
completed during the second and third quarters of 2009. In June
2009, EME completed through its subsidiary, Viento Funding
II,&amp;nbsp;Inc., a non-recourse financing of its interests in the
Wildorado, San Juan Mesa and Elkhorn Ridge wind projects. The
financing included a $189&amp;nbsp;million seven-year term loan and a
$13&amp;nbsp;million letter of credit facility which replaced project
letters of credit previously issued under the EME corporate credit
facility. Interest under the term loan accrues at LIBOR plus 3.875%
initially, with the rate increasing 0.25% on the third and sixth
anniversaries of the closing date. Viento Funding II entered into
interest rate swap agreements to hedge the majority of the variable
interest rate under the term loan. For further details regarding
the interest rate swap agreements, see Note&amp;nbsp;3&amp;#151;Derivative
Instruments.&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; In July
2009, Viento Funding II amended the credit agreement to add a
working capital facility. Availability under the working capital
facility is initially $3.8&amp;nbsp;million and steps up semi-annually
to $5.2&amp;nbsp;million by maturity. The agreement restricts the use
of proceeds from the working capital facility to operation and
maintenance expenditures at these three wind projects.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;In
September 2009, Midwest Generation and EME repaid $200&amp;nbsp;million
and $163&amp;nbsp;million, respectively, of borrowings under their
respective credit facilities. The outstanding balances under
Midwest Generation's working capital facility of $275&amp;nbsp;million
and EME's corporate credit facility of $188&amp;nbsp;million were
reported as current portion of long-term obligations on EME's
consolidated balance sheet and were repaid in October
2009.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Commitments&lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;i&gt;Capital
Improvements&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;At
September&amp;nbsp;30, 2009, EME's subsidiaries had firm commitments to
spend approximately $87&amp;nbsp;million during the remainder of 2009
and $31&amp;nbsp;million in 2010 on capital and construction
expenditures. The majority of these expenditures relate to
non-environmental improvements at both the Illinois Plants and the
Homer City facilities and the construction of wind projects. These
expenditures are planned to be financed by cash on hand and cash
generated from operations.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;i&gt;Turbine
Commitments&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;EME
has entered into various turbine supply agreements with vendors to
support its wind development efforts. As of September&amp;nbsp;30,
2009, EME has commitments to purchase 419 wind turbines
(785&amp;nbsp;MW) with obligations of $718&amp;nbsp;million due in 2010. In
October 2009, EME extended and reduced payment obligations through
two agreements. EME, through its subsidiary, Big Sky
Wind,&amp;nbsp;LLC, (Big Sky) entered into turbine financing
arrangements totaling approximately $206&amp;nbsp;million for the
purchase of 114 wind turbines (240&amp;nbsp;MW) for the Big Sky wind
project. In October 2009, EME also entered into an amendment to one
of its turbine supply agreements which no longer obligates EME to
purchase 22 wind turbines (46&amp;nbsp;MW). EME has deferred all
remaining 2009 payments to 2010. EME continues to actively
negotiate with its turbine suppliers to match turbine delivery and
payment dates to the deployment of turbines at individual wind
projects.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;As
of September&amp;nbsp;30, 2009, EME has recorded wind turbine deposits
of $395&amp;nbsp;million included in other long-term assets in its
consolidated balance sheet. EME has 67 wind turbines (163&amp;nbsp;MW)
in storage to be used for future wind projects with commitments on
these turbines of $6&amp;nbsp;million remaining in 2009 and
$8&amp;nbsp;million in 2010. EME has recorded $191&amp;nbsp;million in
other long-term assets on its consolidated balance sheet related to
wind turbines in storage.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;EME
can elect under one of its existing turbine supply agreements to
terminate the agreement for convenience which, if terminated in its
entirety, would further reduce turbine commitments by
$181&amp;nbsp;million during 2010. In the event of such termination by
EME, a write-off of approximately $45&amp;nbsp;million would be
recognized.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;i&gt;Fuel Supply
Contracts&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;At
September&amp;nbsp;30, 2009, Midwest Generation and EME Homer City had
fuel purchase commitments with various third-party suppliers for
the purchase of coal. Based on the contract provisions, which
consist of fixed prices subject to adjustment clauses, these
minimum commitments are currently estimated to aggregate
$1.0&amp;nbsp;billion, summarized as follows: remainder of
2009&amp;#151;$101&amp;nbsp;million, 2010&amp;#151;$461&amp;nbsp;million,
2011&amp;#151;$255&amp;nbsp;million, and 2012&amp;#151;$212&amp;nbsp;million.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;i&gt;Coal Transportation
Agreements&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;At
September&amp;nbsp;30, 2009, Midwest Generation and EME Homer City had
contractual agreements for the transport of coal to their
respective facilities. The commitments under these contracts are
based on either actual coal purchases or minimum quantities.
Accordingly, contractual obligations for transportation based on
actual coal purchases are derived from committed coal volumes set
forth in fuel supply contracts. These minimum commitments are
currently estimated to aggregate $507&amp;nbsp;million, summarized as
follows: remainder of 2009&amp;#151;$67&amp;nbsp;million,
2010&amp;#151;$276&amp;nbsp;million, and 2011&amp;#151;$164&amp;nbsp;million.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;i&gt;Standby Letters of
Credit&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;At
September&amp;nbsp;30, 2009, standby letters of credit under EME and
its subsidiaries' credit facilities aggregated $119&amp;nbsp;million
and were scheduled to expire as follows: $6&amp;nbsp;million in 2009
and $113&amp;nbsp;million in 2010.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Guarantees and
Indemnities&lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;EME
and certain of its subsidiaries have various financial and
performance guarantees and indemnifications which are issued in the
normal course of business. As discussed below, these contracts
include performance guarantees, guarantees of debt and
indemnifications.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;i&gt;Tax Indemnity
Agreements&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;In
connection with the sale-leaseback transactions related to the
Homer City facilities in Pennsylvania, the Powerton and Joliet
Stations in Illinois and, previously, the Collins Station in
Illinois, EME and several of its subsidiaries entered into tax
indemnity agreements. Although the Collins Station lease terminated
in April 2004, Midwest Generation's tax indemnity agreement with
the former lease equity investor is still in effect. Under these
tax indemnity agreements, these entities agreed to indemnify the
lessors in the sale-leaseback transactions for specified adverse
tax consequences that could result in certain situations set forth
in each tax indemnity agreement, including specified defaults under
the respective leases. The potential indemnity obligations under
these tax indemnity agreements could be significant. Due to the
nature of these potential obligations, EME cannot determine a
maximum potential liability which would be triggered by a valid
claim from the lessors. EME has not recorded a liability related to
these indemnities.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;i&gt;Indemnities
Provided as Part of the Acquisition of the Illinois
Plants&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;In
connection with the acquisition of the Illinois Plants, EME agreed
to indemnify Commonwealth Edison with respect to specified
environmental liabilities before and after December&amp;nbsp;15, 1999,
the date of sale. The indemnification claims are reduced by any
insurance proceeds and tax benefits related to such claims and are
subject to a requirement that Commonwealth Edison takes all
reasonable steps to mitigate losses related to any such
indemnification claim. Due to the nature of the obligation under
this indemnity, a maximum potential liability cannot be determined.
This indemnification for environmental liabilities is not limited
in term and would be triggered by a valid claim from Commonwealth
Edison. Commonwealth Edison has advised EME that Commonwealth
Edison believes it is entitled to indemnification for all
liabilities, costs, and expenses that it may be required to bear as
a result of the litigation discussed below under
"&amp;#151;Contingencies&amp;#151;Midwest Generation New Source Review Lawsuit."
Except as discussed below, EME has not recorded a liability related
to the environmental indemnity specified in the acquisition
agreement.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Midwest
Generation entered into a supplemental agreement with Commonwealth
Edison and Exelon Generation Company,&amp;nbsp;LLC on February&amp;nbsp;20,
2003 to resolve a dispute regarding interpretation of its
reimbursement obligation for asbestos claims under the
environmental indemnities set forth in the Asset Sale Agreement.
Under this supplemental agreement, Midwest Generation agreed to
reimburse Commonwealth Edison and Exelon Generation for 50% of
specific asbestos claims pending as of February 2003 and related
expenses less recovery of insurance costs, and agreed to a sharing
arrangement for liabilities and expenses associated with future
asbestos-related claims as specified in the agreement. As a general
matter, Commonwealth Edison and Midwest Generation apportion
responsibility for future asbestos-related claims based upon the
number of exposure sites that are Commonwealth Edison locations or
Midwest Generation locations. The obligations under this agreement
are not subject to a maximum liability. The supplemental agreement
had an initial five-year term with an automatic renewal provision
for subsequent one-year terms (subject to the right of either party
to terminate); pursuant to the automatic renewal provision, it has
been extended until February 2010. There were approximately 203
cases for which Midwest Generation was potentially liable and that
had not been settled and dismissed at September&amp;nbsp;30, 2009.
Midwest Generation had recorded a $50&amp;nbsp;million liability at
September&amp;nbsp;30, 2009 related to this matter.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;The
amounts recorded by Midwest Generation for the asbestos-related
liability are based upon a number of assumptions. Future events,
such as the number of new claims to be filed each year, the average
cost of disposing of claims, as well as the numerous uncertainties
surrounding asbestos litigation in the United States, could cause
the actual costs to be higher or lower than projected.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;i&gt;Indemnity Provided
as Part of the Acquisition of the Homer City
Facilities&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;In
connection with the acquisition of the Homer City facilities, EME
Homer City agreed to indemnify the sellers with respect to
specified environmental liabilities before and after the date of
sale. Payments would be triggered under this indemnity by a valid
claim from the sellers. EME guaranteed the obligations of EME Homer
City. Due to the nature of the obligation under this indemnity
provision, it is not subject to a maximum potential liability and
does not have an expiration date. For discussion of the NOV
received by EME Homer City and associated indemnity claims, see
"&amp;#151;Contingencies&amp;#151;EME Homer City New Source Review Notice of
Violation." EME has not recorded a liability related to this
indemnity.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;i&gt;Indemnities
Provided under Asset Sale Agreements&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;The
asset sale agreements for the sale of EME's international assets
contain indemnities from EME to the purchasers, including
indemnification for taxes imposed with respect to operations of the
assets prior to the sale and for pre-closing environmental
liabilities. Not all indemnities under the asset sale agreements
have specific expiration dates. Payments would be triggered under
these indemnities by valid claims from the sellers or purchasers,
as the case may be. At September&amp;nbsp;30, 2009, EME had recorded a
liability of $96&amp;nbsp;million (of which $49&amp;nbsp;million is
classified as a current liability) related to these
matters.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;In
connection with the sale of various domestic assets, EME has from
time to time provided indemnities to the purchasers for taxes
imposed with respect to operations of the asset prior to the sale.
EME has also provided indemnities to purchasers for items specified
in each agreement (for example, specific pre-existing litigation
matters and/or environmental conditions). Due to the nature of the
obligations under these indemnity agreements, a maximum potential
liability cannot be determined. Not all indemnities under the asset
sale agreements have specific expiration dates. Payments would be
triggered under these indemnities by valid claims from the sellers
or purchasers, as the case may be. At September&amp;nbsp;30, 2009, EME
had recorded a liability of $2&amp;nbsp;million related to these
matters.&lt;/font&gt;&lt;/p&gt;

&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;i&gt;Midwest Generation
New Source Review Lawsuit&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;On
August&amp;nbsp;3, 2007, Midwest Generation received an NOV from the US
EPA alleging that, beginning in the early 1990s and into 2003,
Midwest Generation or Commonwealth Edison performed repair or
replacement projects at six Illinois coal-fired electric generating
stations in violation of the PSD requirements and of the New Source
Performance Standards of the CAA, including alleged requirements to
obtain a construction permit and to install best available control
technology at the time of the projects. The US EPA also alleged
that Midwest Generation and Commonwealth Edison violated certain
operating permit requirements under Title V of the CAA. Finally,
the US EPA alleged violations of certain opacity and particulate
matter standards at the Illinois Plants. The NOV did not specify
the penalties or other relief that the US EPA sought for the
alleged violations. At approximately the same time, Commonwealth
Edison received an NOV substantially similar to the Midwest
Generation NOV. Midwest Generation, Commonwealth Edison, the US
EPA, and the DOJ, along with several Chicago-based environmental
action groups, had been in confidential talks designed to explore
the possibility of a settlement.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;On
August&amp;nbsp;27, 2009, the US EPA and the State of Illinois filed a
complaint in the Northern District of Illinois against Midwest
Generation, but not Commonwealth Edison, based in part on the
allegations in the NOV. In addition to seeking penalties ranging
from $25,000 to $37,500 per violation, per day, the complaint calls
for an injunction ordering Midwest Generation to install best
available control technology at all units subject to the complaint;
to obtain new PSD or New Source Review permits for those units; to
amend its applications under Title V of the CAA; to conduct audits
of its operations to determine whether any additional modifications
have occurred; and to offset and mitigate the harm to public health
and the environment caused by the alleged CAA violations. By motion
dated October&amp;nbsp;9, 2009, the environmental groups that had been
involved in previous settlement discussions asked the court to
allow them to intervene in the August&amp;nbsp;27 action. The parties
have been instructed to meet and confer on the proposed
intervention. Midwest Generation plans to vigorously defend against
the allegations in the complaint.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Midwest
Generation cannot predict the outcome of these matters or estimate
the impact on its facilities, its results of operations, financial
position or cash flows.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;i&gt;EME Homer City New

&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;On
June&amp;nbsp;12, 2008, EME Homer City received an NOV from the US EPA
alleging that, beginning in 1988, EME Homer City (or former owners
of the Homer City facilities) performed repair or replacement
projects at Homer City Units 1 and 2 without first obtaining
construction permits as required by the PSD requirements of the
CAA. The US EPA also alleges that EME Homer City has failed to file
timely and complete Title V permits. The NOV does not specify the
penalties or other relief that the US EPA seeks for the alleged
violations. On June&amp;nbsp;30, 2009, the US EPA issued a request for
information to EME Homer City under Section&amp;nbsp;114 of the CAA.
EME Homer City is working on a response to the request. EME Homer
City has met with the US EPA and has expressed its intent to
explore the possibility of a settlement. If no settlement is
reached and the DOJ files suit, litigation could take many years to
resolve the issues alleged in the NOV. EME Homer City cannot
predict the outcome of this matter or estimate the impact on its
facilities, its results of operations, financial position or cash
flows.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;EME
Homer City has sought indemnification for liability and defense
costs associated with the NOV from the sellers under the asset
purchase agreement pursuant to which EME Homer City acquired the
Homer City facilities. The sellers responded by denying the
indemnity obligation, but accepting a portion of defense costs
related to the claims.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;EME
Homer City notified the sale-leaseback owner participants of the
Homer City facilities of the NOV under the operative indemnity
provisions of the sale-leaseback documents. The owner participants
of the Homer City facilities, in turn, have sought indemnification
and defense from EME Homer City for costs and liability associated
with the EME Homer City NOV. EME Homer City responded by
undertaking the indemnity obligation and defense of the
claims.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Environmental
Matters and Regulations&lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;The
construction and operation of power plants are subject to federal,
state and local environmental laws and regulations, which typically
require a lengthy and complex process for obtaining licenses,
permits and approvals for construction, operation or modification
of a project or generating facility. EME believes that it is in
substantial compliance with existing environmental regulatory
requirements. However, possible developments, such as the
promulgation of more stringent environmental laws and regulations,
proceedings that may be initiated by environmental and other
regulatory authorities, cases in which new theories of liability
are recognized, and settlements agreed to by other companies that
establish precedent or expectations for the power industry, could
affect the costs and the manner in which EME and its subsidiaries
conduct their businesses and could require substantial additional
capital or operational expenditures or the ceasing of operations at
certain of their facilities. There is no assurance that EME's
financial position and results of operations would not be
materially adversely affected. EME is unable to predict the precise
extent to which additional laws and regulations may affect its
future operations and capital expenditure requirements. For a more
complete discussion of EME's environmental contingencies, refer to
"Note&amp;nbsp;12&amp;#151;Commitments and Contingencies&amp;#151;Environmental Matters
and Regulations" on page&amp;nbsp;156 of EME's annual report on
Form&amp;nbsp;10-K for the year ended December&amp;nbsp;31, 2008. For
further discussion of EME's environmental and regulatory risks,
refer to "Item&amp;nbsp;1A. Risk Factors&amp;#151;Regulatory and Environmental
Risks" on page&amp;nbsp;32 of EME's annual report on Form&amp;nbsp;10-K for
the year ended December&amp;nbsp;31, 2008.&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;
&lt;font size="2"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;With
respect to EME's potential liabilities arising under the
Comprehensive Environmental Response, Compensation and Liability
Act of 1980, commonly referred to as CERCLA, or similar laws for
the investigation and remediation of contaminated property, EME
accrues a liability to the extent the costs are probable and can be
reasonably estimated. Midwest Generation has accrued approximately
$5&amp;nbsp;million at September&amp;nbsp;30, 2009 for estimated
environmental investigation and remediation costs for the Illinois
Plants. This estimate is based upon the number of sites, the scope
of work and the estimated costs for investigation and/or
remediation where such expenditures could be reasonably estimated.
Future estimated costs may vary based on changes in regulations or
requirements of federal, state, or local governmental agencies,
changes in technology, and actual costs of disposal. In addition,
future remediation costs will be affected by the nature and extent
of contamination discovered at the sites that requires remediation.
Given the prior history of the operations at its facilities, EME
cannot be certain that the existence or extent of all contamination
at its sites has been fully identified. However, based on available
information, management believes that future costs in excess of the
amounts disclosed on all known and quantifiable environmental
contingencies will not be material to EME's financial
position.&lt;/font&gt;&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;
