updated to reflect EME's financing activities completed during the second
quarter of 2009. In June 2009, EME completed through its subsidiary, Viento
Funding II,&amp;nbsp;Inc., a non-recourse portfolio financing of its interests in
the Wildorado, San Juan Mesa and Elkhorn Ridge wind projects. The portfolio
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&amp;nbsp;II has 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. &lt;/FONT&gt;&lt;/P&gt;

size=2&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;At June&amp;nbsp;30, 2009,
EME's subsidiaries had firm commitments to spend approximately $110&amp;nbsp;million
during the remainder of 2009 and $14&amp;nbsp;million in 2010 on capital and
construction expenditures. The majority of these expenditures relate to the
construction of wind projects and non-environmental improvements at both the
Illinois Plants and the Homer City facilities. 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;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 had entered into
various turbine supply agreements with vendors to support its wind development
efforts. At June&amp;nbsp;30, 2009, EME had secured the rights to 484 wind turbines
(942 MW) for use in future projects for an aggregate purchase price of
$1.2&amp;nbsp;billion, with remaining commitments of $596&amp;nbsp;million in 2009 and
$242&amp;nbsp;million in 2010. At June&amp;nbsp;30, 2009, EME had recorded wind turbine
deposits of $410&amp;nbsp;million, included in other long-term assets on its
consolidated balance sheet. EME has executed non-binding letter agreements with
two of its vendors to provide vendor financing. EME and such vendors are in the
process of negotiating definitive agreements based on the non-binding letter
agreements, but there is no assurance that final binding agreements will be
executed or executed on terms that conform to the letter agreements. If
definitive agreements are executed substantially in accordance with the terms of
the letter agreements, turbine commitments would be reduced to approximately
$191&amp;nbsp;million in 2009, $229&amp;nbsp;million in 2010, and $210&amp;nbsp;million in
2011, and the remaining $206&amp;nbsp;million due based on specified conditions
(expected during the time period of 2011 and 2014). These commitments would be
further reduced during this period if a third turbine supplier agrees to provide
vendor financing. Furthermore, EME can elect under the existing turbine supply
agreement with this supplier to terminate the agreement for convenience which
would further reduce turbine commitments to $9&amp;nbsp;million in 2009 and
$49&amp;nbsp;million in 2010 (in such case, EME would write off approximately
$90&amp;nbsp;million in previously made non-refundable deposits). &lt;/FONT&gt;&lt;/P&gt;

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 $417&amp;nbsp;million,
summarized as follows: remainder of 2009&amp;#151;$230&amp;nbsp;million,
2010&amp;#151;$177&amp;nbsp;million, and 2011&amp;#151;$10&amp;nbsp;million. &lt;/FONT&gt;&lt;/P&gt;

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;&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 NOV discussed below under
"&amp;#151;Contingencies&amp;#151;Midwest Generation New Source Review Notice of Violation" and
potential litigation by private groups related to the NOV. 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;

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 &lt;!-- SEQ.=20,FOLIO='25',FILE='DISK114:[09ZCF1.09ZCF45001]XE45001B.;2',USER='CMATTI',CD=';5-AUG-2009;18:40' --&gt;&lt;A
name=page_xxx45001_1_26&gt;&lt;/A&gt;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 214 cases for which Midwest Generation was
potentially liable and that had not been settled and dismissed at June&amp;nbsp;30,
2009. Midwest Generation had recorded a $51&amp;nbsp;million liability at
June&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;&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;

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;

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

produced unjust and unreasonable capacity prices. On September&amp;nbsp;19, 2008,
the FERC dismissed the RPM Buyers' complaint, finding that the RPM Buyers had
failed to allege or prove that any party violated PJM's tariff and market rules,
and that the prices determined during the transition period were determined in
accordance with PJM's FERC-approved tariff. On October&amp;nbsp;20, 2008, the RPM
Buyers requested rehearing of the FERC's order dismissing their complaint. On
June&amp;nbsp;18, 2009, the FERC denied rehearing of the order. &lt;/FONT&gt;&lt;/P&gt;

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 Prevention of Significant Deterioration
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
alleges that Midwest Generation and Commonwealth Edison violated certain
operating permit requirements under Title V of the CAA. Finally, the US EPA
alleges violations of certain opacity and particulate matter standards at the
Illinois Plants. The NOV does not specify the penalties or other relief that the
US EPA seeks for the alleged violations. Midwest Generation, Commonwealth
Edison, the US EPA, and the DOJ are in talks designed to explore the possibility
of a settlement. If the settlement talks fail and the DOJ files suit, litigation
could take many years to resolve the issues alleged in the NOV. &lt;/FONT&gt;&lt;/P&gt;

Midwest Generation and Commonwealth Edison received a letter signed by several
Chicago-based environmental action groups stating that, in light of the NOV, the
groups are examining the possibility of filing a citizen suit against Midwest
Generation and Commonwealth Edison based presumably on the same or similar
theories advanced by the US EPA in the NOV. On July&amp;nbsp;28, 2009, Midwest
Generation received a sixty-day Notice of Intent to Sue signed by the same
groups, stating their intent to file&amp;nbsp;a citizen suit alleging exceedances of
CAA opacity limits and violations of permit requirements related to monitoring

believes it is entitled to indemnification for all liabilities, costs, and
expenses that it may be required to bear as a result of the NOV. By letter dated
August&amp;nbsp;16, 2007, Commonwealth Edison tendered a request for indemnification
to EME for all liabilities, costs, and expenses that Commonwealth Edison may be

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 Prevention of Significant Deterioration
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 &lt;!-- SEQ.=22,FOLIO='27',FILE='DISK114:[09ZCF1.09ZCF45001]XG45001A.;2',USER='CMATTI',CD=';5-AUG-2009;18:40' --&gt;&lt;A

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

&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 environmental regulation by federal,
state and local authorities. EME believes that it is in substantial compliance
with existing environmental regulatory requirements. However, possible future
developments, such as the promulgation of more stringent environmental laws and
regulations, future 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.

&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;Typically, environmental
laws and regulations require a lengthy and complex process for obtaining
licenses, permits and approvals prior to construction, operation or modification
of a project or generating facility. Meeting all the necessary requirements can
delay or sometimes prevent the completion of a proposed project, as well as
require extensive modifications to existing projects, which may involve
significant capital or operational expenditures. If EME fails to comply with
applicable environmental laws, it may be subject to injunctive relief or
penalties and fines imposed by federal and state regulatory authorities.
&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
June&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 &lt;!-- SEQ.=23,FOLIO='28',FILE='DISK114:[09ZCF1.09ZCF45001]XG45001A.;2',USER='CMATTI',CD=';5-AUG-2009;18:40' --&gt;&lt;A
name=page_xxx45001_1_29&gt;&lt;/A&gt;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.
