| |  |  | our inability to access effectively the over-the-counter and exchange-based commodity markets or changes in commodity market liquidity or other commodity market
conditions, which may affect our ability to engage in asset management and proprietary trading activities as expected, or result in material extraordinary gains or losses from open positions in fuel oil or other commodities;

PART I



|Item 1. | Business
|------- | --------

Overview

We are a competitive energy company that produces and sells electricity. We own or lease 10,280 MW of electric generating capacity located in
markets in the Mid-Atlantic (5,244 MW) and Northeast regions (2,689 MW) and in California (2,347 MW). We also operate an integrated asset management and energy marketing organization based in Atlanta, Georgia. Our customers are ISOs, investor-owned
utilities, municipal systems, aggregators, electric cooperative utilities, producers, generators, marketers and large industrial customers. Our generating portfolio is diversified across fuel types, power markets and dispatch types and serves
customers located near many major metropolitan load centers. Our total net generating capacity is approximately 31% baseload, 57% intermediate and 12% peaking.

Mirant Americas Generation is a Delaware limited liability company and an indirect wholly-owned subsidiary of Mirant. Mirant Corporation was incorporated in Delaware on September 23, 2005. Pursuant to the Plan
for Mirant and certain of its subsidiaries, on January 3, 2006, New Mirant emerged from bankruptcy and acquired substantially all of the assets of Old Mirant, a corporation that was formed in Delaware on April 3, 1993, and that had been
named Mirant Corporation prior to January 3, 2006.

In the third quarter of 2006, Mirant commenced auction processes to sell six U.S.
natural gas-fired facilities including our indirectly owned Zeeland and Bosque facilities. On May 1, 2007, we completed the sale of the Zeeland and Bosque natural gas-fired facilities. In addition, on May 7, 2007, we completed the sale of
Mirant NY-Gen, an indirect wholly-owned subsidiary. In accordance with Mirant North Americas debt covenants, approximately $524 million of the proceeds from the sale of the Zeeland and Bosque facilities are being reinvested in the
business of Mirant North America. At December 31, 2007, $273 million of such proceeds have been reinvested in Mirant North America. See Note 10 to our consolidated and combined financial statements contained elsewhere in this report for
additional information regarding the accounting for these facilities as discontinued operations.

On April 9, 2007, Mirant announced
that its Board of Directors had decided to explore strategic alternatives to enhance stockholder value. In the exploration process, the Board of Directors considered whether the interests of stockholders would be best served by returning excess cash
from the sale proceeds to stockholders, with Mirant continuing to operate its retained businesses or, alternatively, whether greater stockholder value would be achieved by entering into a transaction with another company, including a sale of Mirant
in its entirety. On November 9, 2007, Mirant announced the conclusion of the strategic review process. Mirant plans to return a total of $4.6 billion of excess cash to its stockholders.

The accompanying consolidated financial statements include the accounts of Mirant Americas Generation and reflect the effects of the Plan as of
December 31, 2005, including:



| |  |  | The contribution by Mirant of its interest in Mirant Potomac River and Mirant Peaker to our indirect wholly-owned subsidiary, Mirant Mid-Atlantic, and its interest
in Mirant Zeeland and in Mirant Americas Energy Marketing, Mirant Americas Development, Inc., Mirant Americas Production Company, Mirant Americas Energy Capital, LLC, Mirant Americas Energy Capital Assets, LLC, Mirant Americas Development
Capital, LLC, Mirant Americas Retail Energy Marketing, LP, and Mirant Americas Gas Marketing I-XV, LLCs (collectively, the Trading Debtors) to Mirant North America. All of the contributed subsidiaries were under the common control of
Mirant and are collectively referred to as the Contributed Subsidiaries.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The transfer of the trading and marketing business of the Trading Debtors to Mirant Energy Trading, a wholly-owned subsidiary of Mirant North America. After these
transfers took place on January 31, 2006, the Trading Debtors were transferred to a trust created under the Plan that is not affiliated with us.

Eliminations are primarily related to intercompany sales of emissions allowances and interest on
intercompany notes receivable and notes payable. For selected financial information about our business segments, see Note 13 to our consolidated and combined financial statements contained elsewhere in this report. See Item 2. Properties for a
complete list of our operating plants.

Commercial Operations

Our commercial operations consist primarily of procuring fuel, dispatching electricity, hedging the production and sale of electricity by our generating facilities, managing fuel oil and providing logistical support
for the operation of our facilities (for example, by procuring transportation for coal). We typically sell the electricity we produce into the wholesale market at prices in effect at the time we produce it (the spot price).

##### Table of Contents

Spot prices for electricity are volatile, as are prices for fuel and emissions allowances, and in order to reduce the risk of that volatility and achieve
more predictable financial results, it is our strategy to enter into hedgesforward sales of electricity into the wholesale market and forward purchases of fuel and emissions allowances to allow us to produce and sell the electricityfor
various time periods. In addition, given the high correlation between natural gas prices and electricity prices, we enter into forward sales of natural gas to hedge our exposure to changes in the price of electricity. We procure our hedges in OTC
transactions or on exchanges where electricity, fuel and emissions allowances are broadly traded, or through specific transactions with buyers and sellers, using futures, forwards, swaps and options. We also sell capacity and ancillary services
where there are markets for such products and when it is economic to do so. In addition to selling the electricity we produce and buying the fuel and emissions allowances we need to produce electricity (asset management), we buy and sell
some electricity, fuel and emissions allowances as part of our proprietary trading and fuel oil management activities. Proprietary trading is a small part of our commercial operations. We engage in proprietary trading to gain information about the
markets to support our asset management and to take advantage of selected opportunities that we identify from time to time. All of our commercial activities are governed by a comprehensive Risk Management Policy, which requires that our hedging
activities with respect to our assets be risk-reducing and sets limits on the size of positions and VaR in our proprietary trading and fuel oil management activities.

We use dispatch models to assist us in making daily decisions regarding the quantity and price of the power our facilities will generate and sell into the markets. We bid the energy from our generating facilities into
the day-ahead energy market and sell ancillary services through the ISO markets. We sell capacity either bilaterally or through auction processes in each ISO in which we participate. We work with the ISOs and RTOs in real time to ensure that our
generating facilities are dispatched economically to meet the reliability needs of the market.

We economically hedge a substantial portion
of our Mid-Atlantic coal-fired baseload generation and certain of our Northeast coal, gas and oil-fired generation through OTC transactions. A significant portion of our hedges are financial swap transactions that are senior unsecured obligations of
Mirant Mid-Atlantic and do not require the posting of cash collateral either for initial margin or for securing exposure as a result of changes in power or natural gas prices. However, we generally do not hedge our intermediate and peaking units for
tenors greater than 12 months. At February 25, 2008, we were economically hedged as follows:



|        |  |                                                     |   |  |      |   |  |      |   |  |      |   |  |      |

Our commercial operations manage the acquisition and utilization of emissions allowances for our
generating facilities. Primarily as a result of the pollution control equipment we are installing to comply with the requirements of the Maryland Healthy Air Act, we anticipate that we will have significant excess emissions allowances in future
periods. We plan to continue to maintain some emissions allowances in excess of expected generation in case our actual generation exceeds our current forecasts for future periods and for possible future additions of generating capacity. During the
fourth quarter of 2007, we began a program to sell excess emissions allowances, dependent upon market conditions. We sold approximately $24 million of excess emissions allowances and recognized a gain of $22 million, which is included in gain on
sales of assets in the consolidated statement of operations for the year ended December 31, 2007. At December 31, 2007, the estimated fair value of our excess emissions allowances exceeded the carrying value recorded on our consolidated
balance sheet by approximately $200 million.

While OTC transactions make up a substantial portion of our economic hedge portfolio, at
times we sell non-standard, structured products to customers. Additionally, our California facilities operate under long-term contracted capacity and RMR contracts.

##### Table of Contents

We enter into contracts of varying terms to secure appropriate quantities of fuel to meet the varying
specifications of our generating facilities. For our coal-fired generating facilities, we purchase coal from a variety of suppliers under contracts with terms of varying lengths, some of which extend to 2012. Our hedged percentages for fuel include
transactions for which commercial terms have been negotiated but for which contracts have not yet been executed. Individual transactions may or may not be binding prior to execution of a contract. For our gas-fired units, we typically purchase fuel
under short-term contracts with a variety of suppliers on a day-ahead or monthly basis.

Our coal supply comes primarily from the Central
Appalachian and Northern Appalachian coal regions. All of our coal is delivered by rail; however, we are in the process of constructing a barge unloading facility at our Morgantown station that is expected to become operational in the third quarter
of 2008. The barge unloader will enable us to receive coal from international locations as well. We monitor coal supply and delivery logistics carefully and, despite occasional interruptions of scheduled deliveries, to date we have managed to avoid
any significant effects on our operations. We maintain an inventory of coal at our coal-fired facilities for this purpose. Interruptions of scheduled deliveries can result from a variety of disruptions, including strikes, rail system disruptions or
severe weather.

Mid-Atlantic Region

We own or lease four generating facilities in the Mid-Atlantic region with total net generating capacity of 5,244 MW. Our Mid-Atlantic region had a combined 2007 net capacity factor of 37%.

Power generated by our Mid-Atlantic facilities is sold into the PJM market. For a discussion of the PJM market, see Regulatory Environment
below. We have participated in standard offer service auctions in Maryland and Washington, D.C. Power sales, either directly through these auctions or indirectly through subsequent market transactions that are a result of the auction process, serve
as economic hedges for the Mid-Atlantic facilities.

The following table presents the details of our Mid-Atlantic generating facilities:

The Chalk Point facility is our largest generating facility. It consists of two coal-fired
baseload units, two dual-fueled (oil and gas) intermediate units and two oil-fired and five dual-fueled (oil and gas) peaking units. Our next largest facility is the Morgantown facility. It consists of two dual-fueled (coal and oil) baseload units
and six oil-fired peaking units. The Dickerson facility has three coal-fired baseload units, and one oil-fired and two dual-fueled (oil and gas) peaking units. The Potomac River station has three coal-fired baseload units and two coal-fired
intermediate units.

On May 23, 2007, the Virginia State Air Pollution Control Board directed the Virginia DEQ to issue a
state operating permit (the Permit) for the Potomac River facility that significantly restricted the facilitys operations by imposing stringent limits on its SO2 emissions and constraining unit operations so that no more than three
of the facilitys five units can operate at one time. We think these limits and constraints are unreasonable and arbitrary. The Virginia DEQ issued the Permit as directed on June 1, 2007. In June 2007, Mirant Potomac River filed a
petition for appeal in the Circuit Court of the City of Richmond, Virginia, seeking to set aside the Virginia State Air Pollution Control Boards directive of May 23, 2007, and the Permit issued by the Virginia DEQ on June 1, 2007.
The Virginia State Air Pollution Control Board stated that the Permit is intended to be supplanted by a more comprehensive permit that it expects to issue. On October 19, 2007, the Virginia DEQ published a draft of this more comprehensive
permit to solicit comments from the public. If adopted as proposed, this comprehensive permit would also impose stringent limits on SO2 emissions that would continue to limit Mirant Potomac River to operating no more than three of the five units of
the Potomac River generating facility at any one time. On November 30, 2007, the Virginia State Air Pollution Control Board directed the Virginia DEQ to develop an alternative state operating permit that would require completion of a proposed
project to merge the stacks of certain of the units at the Potomac River facility, set a single SO2 emissions limit for the facility and allow for greater operating flexibility. On December 21, 2007, the Virginia DEQ published a draft of this
alternative state operating permit for public comment. If approved as currently drafted with some minor modifications, this alternative state operating permit would enable Mirant Potomac River to operate all five units of the facility at one time.
We anticipate that the Virginia State Air Pollution Control Board will consider the proposed permit in March 2008.

Northeast Region

We own generating facilities in the Northeast region with total net generating capacity of 2,689 MW. Our Northeast region had a
combined 2007 net capacity factor of 22%. The Northeast region is comprised of our facilities located in New York and New England. Generation is sold from our Northeast facilities through a combination of bilateral contracts, spot market
transactions and structured transactions.

The following table presents the details of our facilities in the Northeast Region:

##### Table of Contents

The New York generating facilities consist of the Bowline and Lovett facilities. The Bowline facility is
a dual-fueled (natural gas and oil) facility comprised of two intermediate/peaking units. The Lovett facility consists of one baseload unit capable of burning coal and gas.

Significant developments related to these generating facilities in 2007 were as follows:



| |  |  | On January 26, 2007, Mirant New York, Mirant Bowline (which owns the Bowline facility) and Hudson Valley Gas (collectively the Emerging New York
Entities) filed their Supplemental Joint Chapter 11 Plan of Reorganization with the Bankruptcy Court and subsequently filed amendments to that plan (as subsequently amended, the Supplemental Plan). The Supplemental Plan was
confirmed by the Bankruptcy Court on March 23, 2007, and became effective on April 16, 2007.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In the second quarter of 2007, we shut down units 3 and 4 at the Lovett facility. On October 20, 2007, Mirant Lovett submitted notices of its intent to
discontinue operation of unit 5 at the Lovett generating facility as of midnight on April 19, 2008, to the New York Public Service Commission, the NYISO, Orange and Rockland and several other potentially affected transmission and distribution
companies in New York.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On July 13, 2007, Mirant Lovett (which owns the Lovett facility) filed a plan of reorganization (the Mirant Lovett Plan) with the Bankruptcy Court.
The Mirant Lovett Plan was confirmed by the Bankruptcy Court on September 19, 2007, and became effective on October 2, 2007. As a result of Mirant Lovetts emergence from bankruptcy, we do not have any subsidiaries remaining in
bankruptcy. See Note 11 to our consolidated and combined financial statements contained elsewhere in this report for additional information regarding the emergence from bankruptcy of Mirant Lovett and the Emerging New York Entities.

New England.The Canal facility consists of one oil-fired intermediate unit and one
dual-fueled (oil and gas) intermediate unit. The Kendall facility consists of one combined cycle dual-fueled (oil and gas) baseload unit, two 1,300 pound steam boilers and one simple cycle jet engine peaking unit. The Marthas Vineyard facility
consists of five diesel peaking units.

The capacity, energy and ancillary services from our New England generating units are sold into the
NEPOOL bilateral markets and into the markets administered by the ISO-NE. For a discussion of the NEPOOL and the ISO-NE, see Regulatory Environment below.

California

We own three generating facilities in California with total
net generating capacity of 2,347 MW. Our California facilities had a combined 2007 net capacity factor of 4%. The following table presents the details of our California facilities:

##### Table of Contents

The Pittsburg and Contra Costa facilities are located in Contra Costa County and the Potrero facility is
located in the City of San Francisco. Through the end of 2006, the majority of our California units were subject to RMR arrangements with the CAISO. These agreements are described further under Regulatory Environment below. Pittsburg
unit 7 and Contra Costa unit 6 were not subject to an RMR arrangement, and thus functioned solely as merchant facilities in the CAISO. In 2006, we either sold the output of Pittsburg unit 7 and Contra Costa unit 6 into the market through bilateral
transactions with utilities and other merchant generators, or dispatched the units in the CAISO clearing markets.

On July 28, 2006,
we signed two tolling agreements with PG&E to provide electricity from all our natural gas-fired units in service at Pittsburg and Contra Costa, including Pittsburg unit 7 and Contra Costa unit 6. The agreements are for 100% of the capacity from
these units. The contracts have varying tenors for each unit covering from one to five years, and include capacity of 1,985 MW for 2008 and 2009, 1,303 MW for 2010 and 674 MW for 2011. The contracted capacity for 2007 was 1,985 MW. We receive
monthly capacity payments with bonuses and/or penalties based on guaranteed heat rate and availability tolerances. As a result of these contracts, the Pittsburg and Contra Costa units are no longer subject to the RMR agreements. All of our Potrero
units continue to be subject to RMR arrangements that continue through 2008 and are then renewable annually.

Competitive Environment

The power generating industry is capital intensive and highly competitive. Our competitors include regulated utilities, merchant energy companies,
financial institutions and other companies, including companies owned by hedge funds and private equity funds. For a discussion of competitive factors and the effects of seasonality on our business see Item 1A. Risk Factors. Coal-fired
generation, natural gas-fired generation and nuclear generation currently account for approximately 48%, 22% and 19%, respectively, of the electricity produced in the United States. Hydroelectric and other energy sources account for the remaining
11% of electricity produced.

While the demand for electricity is increasing, supply has not appreciably increased. Given the substantial
time necessary to permit and construct new power plants, we think that the markets in which we operate need to begin the process now of adding generating capacity to meet growing demand. A number of ISOs, including those in markets in which we
operate, have implemented capacity markets as a way to encourage such construction of additional generation, but it is not clear whether and when independent power producers will be sufficiently incented to build this required new generation.

Falling reserve margins, as well as high electricity prices as a result of high natural gas prices, have led to renewed interest in new
coal-fired or nuclear plants. However, the costs to construct new generation facilities are rising and there is substantial environmental opposition to building either coal-fired or nuclear plants.

Regulatory Environment

The electricity industry is
subject to comprehensive regulation at the federal, state and local levels. At the federal level, the FERC has exclusive jurisdiction under the Federal Power Act over sales of electricity at wholesale and the transmission of electricity in
interstate commerce. Each of our subsidiaries that owns a generating facility selling at wholesale or that markets electricity at wholesale is a public utility subject to the FERCs jurisdiction under the Federal Power Act. These
subsidiaries must comply with certain FERC reporting requirements and FERC-approved market rules and are subject to FERC oversight of mergers and acquisitions, the disposition of FERC-jurisdictional facilities and the issuance of securities. In
addition, under the Natural Gas Act, the FERC has limited jurisdiction over certain resales of natural gas, but does not regulate the prices received by our subsidiary, Mirant Energy Trading, that markets natural gas.

The FERC has authorized our subsidiaries that constitute public utilities under the Federal Power Act to sell energy, capacity and certain ancillary
services at wholesale at market based rates. The majority of the output of the generating facilities owned by our subsidiaries is sold pursuant to this authorization, although certain of our



11

##### Table of Contents

facilities sell their output under cost based RMR agreements, as explained below. The FERC may revoke or limit our market based rate authority if it
determines that we possess undue market power in a regional electricity market. Under the Natural Gas Act, our subsidiary that sells natural gas for resale is deemed by the FERC to have blanket certificate authority to undertake these sales at
market based rates. The FERC requires that our public utility subsidiaries with market based rate authority, as well as the subsidiary deemed to have blanket certificate authority to sell natural gas, adhere to certain market behavior rules and
codes of conduct, respectively. If any of our subsidiaries violates the market behavior rules or codes of conduct, the FERC may require a disgorgement of profits or revoke its market based rate authority or blanket certificate authority. If the
FERC were to revoke market based rate authority, our affected public utility subsidiary would have to file a cost based rate schedule for all or some of its sales of electricity at wholesale. If the FERC revoked the blanket certificate authority of
any of our subsidiaries, certain sales of natural gas would be prohibited.

Our facilities operate in ISO/RTO markets. In areas where ISOs
or RTOs control the regional transmission systems, market participants have access to broader geographic markets compared to regions without ISOs and RTOs. ISOs operate real-time and day-ahead energy and ancillary services markets, typically
governed by FERC-approved tariffs and market rules. Some ISOs and RTOs also operate capacity markets. Changes to the applicable tariffs and market rules may be requested by market participants, state regulatory agencies and the system operator,
and such proposed changes, if approved by the FERC, could have a significant effect on our operations and business plan. While participation by transmission-owning public utilities in ISOs and RTOs has been and is expected to continue to be
voluntary, the majority of such public utilities in New England, New York, the Mid-Atlantic and California have joined the applicable ISO/RTO.

Our subsidiaries owning generating facilities were exempt wholesale generators under the PUHCA, as amended. With the repeal of the PUHCA and the adoption of the Public Utility Holding Company Act of 2005, the FERC adopted new regulations
effective February 8, 2006, that allow our subsidiaries owning generating facilities to retain their exempt wholesale generator status.

State and local regulatory authorities have historically overseen the distribution and sale of electricity at retail to the ultimate end user, as well as the siting, permitting and construction of generating and transmission facilities. Our
existing generating facilities are subject to a variety of state and local regulations, including regulations regarding the environment, health and safety, maintenance and expansion of the facilities.

Mid-Atlantic Region.    Our Mid-Atlantic facilities sell electricity into the markets operated by PJM, which the FERC approved
to operate as an ISO in 1997 and as an RTO in 2002. We have access to the PJM transmission system pursuant to PJMs Open Access Transmission Tariff. PJM operates the PJM Interchange Energy Market, which is the regions spot market for
wholesale electricity, provides ancillary services for its transmission customers, performs transmission planning for the region and economically dispatches generating facilities. PJM administers day-ahead and real-time single clearing price markets
and calculates electricity prices based on a locational marginal pricing model. A locational marginal pricing model determines a price for energy at each node in a particular zone taking into account the limitations on transmission of electricity
and losses involved in transmitting energy into the zone, resulting in a higher zonal price when less expensive energy cannot be imported from another zone. Generation owners in PJM are subject to mitigation, which limits the prices that they may
receive under certain specified conditions.

Load-serving entities within PJM are required to have adequate sources of generating capacity.
Our facilities located in the Mid-Atlantic region that sell electricity into the PJM market participate in the reliability pricing model (the RPM) forward capacity market. The RPM capacity auctions are designed to provide forward prices
for capacity that are intended to ensure that adequate resources are in place to meet the regions demand requirements. PJM has conducted four RPM capacity auctions and we began receiving payments in June 2007 as a result of the first auction.
The FERCs orders approving and implementing the PJM RPM capacity auctions are pending review with the United States Court of Appeals. We cannot predict what, if any, effect the appeal process will have on the RPM forward capacity market and
the capacity payments that we receive from that market.

The results of the PJM RPM capacity auctions for the delivery area where our facilities are located were
as follows:

Hereafter, annual auctions will be conducted to procure capacity three years prior to each
delivery period. The first such auction will take place in May 2008, for the provision of capacity from June 1, 2011 to May 31, 2012.

In addition, PJM and the MISO have been directed by the FERC to establish a common and seamless market. The development of a joint market is contingent on the approval of the internal costs to both entities to develop and operate the
infrastructure necessary for joint operations. It is unclear at this time if either the respective entities or the FERC will approve such costs to achieve a common and seamless market.

Northeast Region.    Our New York facilities participate in a market controlled by the NYISO, which replaced the New York
Power Pool. The NYISO provides statewide transmission service under a single tariff and interfaces with neighboring market control areas. To account for transmission congestion and losses, the NYISO calculates energy prices using a locational
marginal pricing model. The NYISO also administers a spot market for energy, as well as markets for installed capacity and services that are ancillary to transmission service, such as operating reserves and regulation service (which balances
resources with load). The NYISOs locational capacity market rules use a demand curve mechanism to determine for every month the required amount of installed capacity as well as installed capacity prices to be paid for three locational
zones: New York City, Long Island and Rest of State. Our facilities operate in the Rest of State locational zone. On April 21, 2005, the FERC issued an order accepting the NYISOs demand curves for 2005/2006, 2006/2007 and 2007/2008 with
minor modifications to the NYISOs proposal. On November 20, 2007, the NYISO filed demand curves for 2008/2009, 2009/2010 and 2010/2011. On January 29, 2008, the FERC issued an order accepting the NYISOs proposal without
modification. The demand curves approved by the FERC may result in increased prices within the NYISO for capacity in those years.

Our New
England facilities participate in a market administered by ISO-NE. Mirant Energy Trading is a member of NEPOOL, which is a voluntary association of electric utilities and other market participants in Connecticut, Maine, Massachusetts, New Hampshire,
Rhode Island and Vermont, and which functions as an advisory organization to ISO-NE. The FERC approved ISO-NE as the RTO for the New England region effective on February 1, 2005, making ISO-NE responsible for market rule filings at the
FERC, in addition to its responsibilities for the operation of transmission systems and administration and settlement of the wholesale electric energy, capacity and ancillary services markets. ISO-NE utilizes a locational marginal pricing model
similar to that used in PJM and NYISO.

On March 6, 2006, a settlement proposal was filed with the FERC among ISO-NE and multiple
market participants for a forward capacity market (the FCM) under which annual capacity auctions would be conducted for supply three years in advance of provision. The settlement provided for a four-year transition period during which
capacity suppliers receive a set price for their capacity commencing on December 1, 2006, and continuing with price escalators through May 31, 2010. The first auction took place in February 2008 for the period June 1, 2010 to
May 31, 2011. The clearing price was $4.50 per kW-month, which was the price floor established as part of the FCM settlement. Our generating facilities will receive $4.50 per kW-month based on our pro-rata amount of the generation that was sold
in the auction. The next auction for the period June 1, 2011 to May 31, 2012, will be held in December 2008. Beginning December 1, 2006, our generating facilities began

receiving capacity revenues under the FCM transition period. The FERCs orders approving and implementing the FCM are pending review with the United
States Court of Appeals. We cannot predict what, if any, effect the appeal process will have on the FCM and the capacity payments we receive under the FCM.

California.    Our California facilities are located inside the CAISOs control area. The CAISO schedules transmission transactions, arranges for necessary ancillary services and
administers a real-time balancing energy market. Most sales in California are pursuant to bilateral contracts, but a significant percentage of electrical energy is sold in the real-time market. The CAISO does not operate a forward market like those
described for PJM and other eastern ISO markets, nor does it currently operate a capacity market.

Mirant Potrero is party to a PPA with
PG&E that from 2006 through 2012 allows PG&E to dispatch and purchase the power output of our Potrero units that have been designated RMR units, which for 2008 includes all of the Potrero units. Under the PPA, through 2008, PG&E is
paying us charges equivalent to the rates we charged during 2004 when the units were designated RMR Contract Condition 2, reduced by $1.4 million for each year since 2004. For 2009 through 2012, the charges for the units that are then subject to the
PPA will be determined annually by the FERC pursuant to the cost based formula rates set forth in the RMR agreement.

The CAISO has
proposed changes to its market design to mirror more closely the eastern ISO markets, but not including a capacity market. Although the CAISO has delayed the market redesign several times, it now expects to fully implement it in 2008. The CPUC has
begun a proceeding to develop, together with the CAISO, a wholesale capacity market. FERC approval would be required for any such capacity market to become effective. We cannot at this time predict the outcome of the CPUC proceeding or the timing or
structure of a wholesale capacity market in California.

Environmental Regulation

Our business is subject to extensive environmental regulation by federal, state and local authorities. We must comply with applicable laws and
regulations, and obtain and comply with the terms of government issued permits. Our costs of complying with environmental laws, regulations and permits are substantial, including significant environmental capital expenditures.

The following table details our estimated environmental capital expenditures, excluding capitalized interest (in millions):

We expect that cash on hand and cash flows from operations will be sufficient to fund these
capital expenditures.

Air Emissions Regulations

Our most significant environmental requirements generally fall under the Clean Air Act and similar state laws. Under the Clean Air Act, we are required to comply with a broad range of mandates concerning air
emissions, operating practices and pollution control equipment. Most of our facilities are located in or near metropolitan areas, including New York City, Boston, San Francisco and Washington D.C., which are classified by the EPA as not achieving
certain NAAQS. As a result of the NAAQS classification of these areas, our operations are subject to more stringent air pollution requirements than applicable to plants located elsewhere.

##### Table of Contents

Various states where we have facilities also have other air quality laws and regulations with increasingly stringent limitations and requirements that will
become effective in future years for our facilities and operations. In the future, we expect increased regulation of our air emissions. Significant air regulatory programs to which we are subject are described below.

Clean Air Interstate Rule (CAIR).    In 2005, the EPA promulgated the CAIR, which established in the eastern United States an
SO2 and NOx cap-and-allowance trading program applicable directly to states and indirectly to generating facilities. These cap-and-trade programs will be implemented in two phases, with the first phase going into effect in 2009 for NOx and 2010 for
SO2 and more stringent caps going into effect in 2015. We are installing pollution control equipment at certain of our coal-fired facilities in Maryland to address the requirements under the Maryland Healthy Air Act, which will also enable us to
satisfy the requirements of the first phase of the CAIR without purchasing additional allowances. The costs of that equipment are included in our estimate of anticipated environmental capital expenditures from 2008 through 2010.

Maryland Healthy Air Act.    The Maryland Healthy Air Act was enacted in April 2006 and requires reductions in NOx, SO2 and
mercury emissions from large coal-fired power facilities. The state law also requires Maryland to join the Regional Greenhouse Gas Initiative (the RGGI), which is discussed below. On August 3, 2006, we announced a plan to
comply with the requirements of the Maryland Healthy Air Act by reducing SO2 emissions by as much as 95% at our Maryland power facilities. The Maryland Healthy Air Act prohibits power facilities from purchasing emissions allowances instead of
installing pollution control equipment. We are installing flue gas desulphurization (FGD) emissions controls at our Chalk Point, Dickerson and Morgantown coal-fired units. In addition, we are installing selective catalytic reduction
(SCR) systems at the Morgantown and Chalk Point coal-fired units, which will reduce NOx emissions by approximately 80%. Together, the FGDs and the SCRs will reduce the emissions of ionic mercury from the three Maryland power facilities.

The Maryland Healthy Air Act imposes tonnage limits for (i) emissions of NOx in 2009 with further reductions in 2012 (including
sublimits during the Ozone Season) and (ii) emissions of SO2 in 2010 with further reductions in 2013. The Maryland Healthy Air Act also imposes restrictions on emissions of mercury beginning in 2010 with further reductions in 2013. The control
equipment we plan to install to meet Maryland state standards will allow our Maryland facilities to comply with the first phase of the CAIR without having to purchase allowances.

We expect to incur total capital expenditures of $1.6 billion through the first quarter of 2010 to comply with the requirements for SO2 and NOx emissions
under the Maryland Healthy Air Act. On July 30, 2007, our indirect subsidiaries Mirant Mid-Atlantic and Mirant Chalk Point entered into an agreement with Stone & Webster, Inc. for engineering, procurement and construction services
relating to the installation of air quality control systems at the Morgantown, Dickerson and Chalk Point coal-fired units. The expected cost under the agreement is approximately $1.1 billion and is a part of the capital expenditures that we expect
to incur to comply with the Maryland Healthy Air Act. We will have extended planned outages during equipment installation. During those outages, we also will perform routine maintenance activities. As of December 31, 2007, we have paid
approximately $500 million for capital expenditures related to the Maryland Healthy Air Act.

Clean Air Mercury Rule
(CAMR).    In 2005, the EPA issued the CAMR, which would have limited total annual mercury emissions from coal-fired power plants across the United States through a two-phased cap-and-trade program. The first phase was to
have begun in 2010 and the second phase was to have begun in 2018. On February 8, 2008, The United States Court of Appeals for the District of Columbia Circuit (the DC Circuit) issued its opinion vacating and remanding two rules
regarding mercury emissions from Electric Generating Units (EGUs). First, the DC Circuits opinion vacated the rule by which the EPA removed EGUs from the list of sources with emissions of hazardous air pollutants subject to
regulation under section 112 of the Clean Air Act which requires maximum achievable control standards. Second, the DC Circuits opinion vacated the EPAs CAMR. At this time, we cannot predict the EPAs action on remand. We expect many
of our coal-fired facilities to emit less mercury as a result of the NOx and SO2 controls that are, or will soon be, installed.

NSR Enforcement Initiative.    In 2001, the EPA requested information
concerning some of our facilities in Maryland and Virginia covering a time period that pre-dates our acquisition or lease of those facilities in December 2000. We responded fully to this request. Under the APSA, Pepco is responsible for fines
and penalties arising from any violation associated with operations prior to our subsidiaries acquisition or lease of the facilities. If a violation is determined to have occurred at any of the facilities, our subsidiary owning or leasing the
facilities may be responsible for the cost of purchasing and installing emissions control equipment, the cost of which may be material. Our subsidiaries owning or leasing the Chalk Point, Dickerson and Morgantown facilities in Maryland are
installing a variety of emissions control equipment on those facilities to comply with the Maryland Healthy Air Act, but that equipment may not include all of the pollution control equipment that could be required if a violation of the EPAs
NSR regulations is determined to have occurred at one or more of those facilities. If such a violation is determined to have occurred after our subsidiaries acquired or leased the facilities or, if occurring prior to the acquisition or lease, is
determined to constitute a continuing violation, our subsidiary owning or leasing the facility at issue could also be subject to fines and penalties by the state or federal government for the period after its acquisition or lease of the facility,
the cost of which may be material, although applicable bankruptcy law may bar such liability for periods prior to January 3, 2006, when the Plan became effective for us and our subsidiaries that own or lease these facilities.

Massachusetts CAIR Implementation.The Commonwealth of Massachusetts Department of Environmental Protection
promulgated regulations to take effect in 2009 to implement the requirements under the federal CAIR to reduce NOx emissions from certain generating facilities. The Massachusetts regulations will require our Canal and Kendall generating facilities,
during the Ozone Season, to reduce their emissions of NOx or utilize emissions allowances greater than what are currently utilized.

New
York CAIR Implementation.    The New York State Department of Environmental Conservation promulgated regulations implementing the NOx and SO2 emissions reductions required by the federal CAIR. Beginning in 2009, the
regulations limit NOx emissions through both an annual cap-and-trade program and through a seasonal cap-and-trade program during the Ozone Season, which will require our Bowline generating facility to reduce its emissions of NOx by running less or
to increase its utilization of emissions allowances. The regulations also implement an SO2 emissions program beginning in 2010 that mandates increased utilization of federal SO2 allowances for every ton of SO2 emitted.

Virginia CAIR Implementation.    In April 2006, Virginia enacted legislation, which among other things granted the
Virginia State Air Pollution Control Board the discretion to prohibit electric generating facilities located in an area that is not in compliance with a particular NAAQS (non-attainment area), from purchasing SO2 and NOx allowances to
achieve compliance under the CAIR. In the fourth quarter of 2007, the Virginia State Air Pollution Control Board approved regulations that it interprets as prohibiting the trading of SO2 and NOx allowances by facilities in non-attainment areas to
satisfy the requirements of the CAIR as implemented by Virginia. The only generating facility in Virginia currently affected is our Potomac River facility which is located in a non-attainment area for ozone and PM2.5. Mirant Potomac River has
appealed these regulations in Virginia state court. We have also petitioned (a) the EPA to reconsider and (b) the United States Court of Appeals for the Fourth Circuit to review the EPAs final rule approving Virginias CAIR
program. Application of these regulations, if not modified or waived, will reduce our flexibility in complying with the CAIR in Virginia beginning in 2009 and could result in operating restrictions for our Potomac River generating facility.

Massachusetts Emissions Standards for Power Plants.    The Commonwealth of Massachusetts Department of
Environmental Protection promulgated regulations affecting certain generating facilities, including our Canal facility, that established emissions output limits beginning in 2006 for NOx and SO2 and beginning in 2008 for CO2 and an annual cap on CO2
emissions beginning in 2008. We are achieving compliance with the NOx and SO2 emissions limits by utilizing lower sulfur fuels and natural gas and by optimizing the operation of our unit with selective catalytic reduction capability. Under our
current operating profile, we are in compliance with the output limit on CO2, and we plan to comply with the annual CO2 cap by purchasing offsets or by making payments into a newly-established Greenhouse Gas Expendable Trust, which is expected to be
finalized during the first quarter of 2008.

New York Consent Decree.    In 2000, the State of New York issued an
NOV to the previous owner of our Lovett facility alleging NSR violations associated with the operation of that facility prior to its acquisition by us. On June 11, 2003, Mirant New York, Mirant Lovett and the State of New York entered into a
consent decree (the 2003 Consent Decree). The 2003 Consent Decree was approved by the Bankruptcy Court on October 15, 2003. Under the 2003 Consent Decree, Mirant Lovett has three options: (1) install emissions controls on
Lovetts two coal-fired units; (2) shut down unit 5 and convert unit 4 to natural gas; or (3) shut down both coal-fired units in 2007 and 2008. We have concluded that the installation of the required emissions controls is uneconomic.

On October 19, 2006, Mirant Lovett notified the New York Public Service Commission, the NYISO, Orange and Rockland and certain other
affected transmission and distribution companies in New York of its intent to discontinue operation of units 3 and 5 of the Lovett facility in April 2007. The 2003 Consent Decree imposed similar requirements with respect to unit 4 that had to
be met by April 30, 2008.

On May 10, 2007, Mirant Lovett entered into an amendment to the 2003 Consent Decree with the State of
New York that switched the deadlines for shutting down units 4 and 5 so that the deadline for compliance by unit 5 was extended until April 30, 2008, and the deadline for unit 4 was shortened. Unit 4 discontinued operation as of
May 7, 2007. In addition, unit 3 discontinued operation because it was uneconomic for the unit to continue to run.

On
October 20, 2007, Mirant Lovett submitted notices of its intent to discontinue operations of unit 5 of the Lovett generating facility as of midnight on April 19, 2008, to the New York Public Service Commission, the NYISO, Orange and
Rockland and several other potentially affected transmission and distribution companies in New York. Barring a new agreement with the State of New York, unit 5 will shut down as required under the amendment to the 2003 Consent Decree.

State Regulation of Greenhouse Gases, including the Regional Green House Gas Initiative (RGGI).    Concern over climate
change has led to significant legislative and regulatory efforts at the state level to limit greenhouse gas emissions. One such effort is the RGGI, a multi-state Northeast regional initiative outlining a cap-and-trade program to reduce CO2 emissions
from units of 25 MW or greater. The RGGI program calls for signatory states to stabilize CO2 emissions to current levels from 2009 to 2015, followed by a 2.5% reduction each year from 2015 to 2018. In August 2006, seven states including New
York signed the RGGI Memorandum of Understanding (MOU), which puts forth a model set of regulations to guide the states in structuring their individual programs. Both Massachusetts and Maryland joined the RGGI in 2007. Our generating
facilities in Maryland, Massachusetts and New York will be affected by the implementation of the RGGI. In August 2007, the Massachusetts Department of Environmental Protection and the Massachusetts Department of Energy Resources proposed
regulations to implement the RGGI. In October 2007, the NYSDEC and the New York State Energy Research and Development Authority issued proposed regulations to implement the RGGI. In January 2008, the MDE issued for public comment proposed
regulations to implement the RGGI. The proposed Maryland regulations include a mechanism such that in the event of carbon credit prices exceeding $7 per ton, we and other Maryland generators will have the option to purchase up to 50% of our needs at
$7 per ton regardless of auction clearing prices.

We expect to produce a total of approximately 15.8 million tons of CO2 at our
Maryland, Massachusetts and New York generating facilities in 2009. If adopted in their current form, the proposed and draft RGGI regulations would require those facilities to obtain allowances to emit CO2. No allowances would be granted to existing
sources of such emissions. Instead, allowances would be made available for such facilities only by purchase through an auction process conducted regionally or through subsequent purchase from a party that held the allowances that had been sold
through the auction. We and a number of other parties have submitted comments on the proposed regulations in Massachusetts and New York, and we expect to comment on the proposed rules to be issued in Maryland. The final form and timing of the
regulations in each state are uncertain. We are continuing to evaluate our options to comply with the RGGI, but its implementation in Maryland, Massachusetts and New York could have a material effect upon our operations and our operating costs,
depending upon the

##### Table of Contents

availability and cost of emissions allowances and the extent to which such costs may be offset by higher market prices to recover increases in operating
costs caused by the RGGI.

In California, emissions of greenhouse gases are governed by the Global Warming Solutions Act (AB
32), which requires that greenhouse gas emissions be reduced to 1990 levels by 2020. AB 32 also requires the California Air Resources Board to develop by January 2009, a greenhouse gas reduction plan for all industrial sectors. That plan could
have a material effect on how we operate our California facilities and the costs of operating the facilities.

Federal Regulation of
Greenhouse Gases.    At the federal level, various bills have been proposed to govern CO2 emissions from generating facilities. We do not know how any law, if ultimately enacted, would affect the state laws and regulations
described. We expect that any federal law governing CO2 emissions would significantly affect our generating facilities.

Water Regulations

We are required under the Clean Water Act to comply with intake and discharge requirements, requirements for technological controls
and operating practices. To discharge water, we must have permits under the Clean Water Act. Such permits typically are subject to review every five years. As with air quality regulations, federal and state water regulations are expected to impose
additional and more stringent requirements or limitations in the future. This is particularly the case for regulatory requirements governing cooling water intake structures, which are subject to regulation under section 316(b) of the Clean
Water Act. A 2007 decision by the United States Court of Appeals for the Second Circuit in Riverkeeper Inc. et al v. EPA, in which the court remanded to the EPA for reconsideration numerous provisions of the EPAs section
316(b) regulations for existing power plants, has created substantial uncertainty about exactly what technologies or other measures will be needed to satisfy section 316(b) requirements in the future and when any new requirements will be
imposed.

Endangered Species Acts.    Mirant Deltas use of water from the Sacramento-San Joaquin Delta at
its Contra Costa and Pittsburg generating facilities potentially affects certain fish species protected under the Federal Endangered Species Act and the California Endangered Species Act. Mirant Delta therefore must maintain authorization under both
statutes to engage in operations that could result in a take of (i.e., harm to) fish of the protected species. In January and February 2006, Mirant Delta received correspondence from the U.S. Fish and Wildlife Service and the Army Corps of Engineers
expressing the view that the Federal Endangered Species Act take authorization for the Contra Costa and Pittsburg facilities was no longer in effect due to changed circumstances. Mirant Delta disagreed with the agencies characterization of its
take authorization as no longer being in effect. In late October 2007, Mirant Delta received correspondence from the U.S. Fish and Wildlife Service, the National Marine Fisheries Service and the Army Corps of Engineers clarifying that Mirant Delta
continued to be authorized to take four species of fish protected under the federal Endangered Species Act. The agencies have initiated a process that will review the environmental effects of Mirant Deltas water usage, including effects on the
protected species of fish. That process could lead to changes in the manner in which Mirant Delta can use river water for the operation of the Pittsburg and Contra Costa generating facilities.

Mirant and Mirant Delta received two letters, one dated September 27, 2007, sent on behalf of the Coalition for a Sustainable Delta, four water
districts, and an individual, and the second dated October 16, 2007, sent on behalf of San Francisco Baykeeper (collectively with the parties sending the September 27, 2007, letter, the Noticing Parties), providing notice that
the Noticing Parties intend to file suit alleging that Mirant Delta has violated, and continues to violate, the federal Endangered Species Act through the operation of its Contra Costa and Pittsburg generating facilities. The Noticing Parties
contend that the facilities use of water drawn from the Sacramento-San Joaquin Delta for cooling purposes results in harm to four species of fish listed as endangered species. The Noticing Parties assert that the take authorizations, a biological
opinion and incidental take statement issued by the National Marine Fisheries Service on October 17, 2002, for three of the fish species and a biological opinion and incidental take statement issued by the U.S. Fish and Wildlife Service on
November 4, 2002, for the fourth fish species, have been violated by Mirant Delta and no longer apply to permit the effects on

##### Table of Contents

the four fish species caused by the operation of the Contra Costa and Pittsburg generating facilities. Following receipt of these letters, Mirant Delta
received the correspondence described above from the U.S. Fish and Wildlife Service, the National Marine Fisheries Service and the Army Corps of Engineers clarifying that Mirant Delta continues to be authorized to take the four species of fish
protected under the federal Endangered Species Act. In a subsequent letter, the Coalition for a Sustainable Delta also alleged violations of the National Environmental Policy Act and the California Endangered Species Act associated with the
operation of Mirant Deltas facilities. Mirant Delta disputes the allegations made by the Noticing Parties. No lawsuits have been filed to date, and San Francisco Baykeeper, on February 1, 2008, withdrew its notice of intent to sue.

Additionally, in September 2007, Mirant Delta signed an amendment to a Memorandum of Agreement with the California Department of Fish and
Game. The amendment requires Mirant Delta to initiate monitoring of the effects on fish of the operations of the Pittsburg and Contra Costa facilities, to prepare an environmental impact report, and to submit within 24 months an application for a
new permit authorizing Mirant Delta to take the protected fish species affected by the operation of its facilities. The amendment extends Mirant Deltas authorization for take of fish species protected under the California Endangered Species
Act until the California Department of Fish and Game completes its consideration of the application for the new permit.

National
Pollution Discharge Elimination System.    On June 8, 2006, Bayview-Hunters Point Community Advocates and Communities for a Better Environment filed a petition challenging the issuance of the National Pollution Discharge
Elimination System (NPDES) permit for our Potrero facility. On February 8, 2007, Bayview-Hunters Point Community Advocates and Communities for a Better Environment filed another petition with a request to amend their initial
petition. On March 21, 2007, the California State Water Resources Control Board notified the parties that petitioners requested that as of March 19, 2007, the two petitions be moved from active status to abeyance. Those petitions
currently remain in abeyance. Additionally, on June 15, 2007, Bayview-Hunters Point Community Advocates and Communities for a Better Environment and San Francisco Baykeeper filed a third petition requesting that the NPDES permits for Potrero
and Mirant Deltas Pittsburg facility be reopened. The State Water Resources Control Board denied that petition on November 27, 2007.

Kendall NPDES and Surface Water Discharge Permit.    On September 26, 2006, the Massachusetts Department of Environmental Protection and the EPA jointly issued to Mirant Kendall a Surface Water Discharge
Permit (SWDP), a water quality certificate and an NPDES permit for the Kendall generating facility. The new permits impose new temperature limits at various points in the Charles River, an extensive temperature, water quality and
biological monitoring program and a requirement to develop and install a barrier net system to reduce fish impingement and entrainment. The provisions regulating the thermal discharge could cause substantial curtailments of the operations of the
Kendall facility. Mirant Kendall has appealed the permits in three proceedings: (1) appeal of the NPDES permit to the Environmental Appeals Board; (2) appeal of the SWDP to the Massachusetts Department of Environmental Protection; and
(3) appeal of the Water Quality Certification to the Massachusetts Department of Environmental Protection. The effect of the permits has been stayed pending the outcome of these appeals. The two appeals to the Massachusetts Department of
Environmental Protection have been stayed pending the outcome of the appeal to the Environmental Appeals Board. On September 28, 2007, the Environmental Appeals Board stayed the appeal proceedings until April 18, 2008, in order for the EPA
to address the sections of the permit that are affected by the EPAs suspension of the 316(b) regulations as described above under Water Regulations. We are unable to predict the outcome of these proceedings.

Wastes, Hazardous Materials and Contamination

Our
facilities are subject to laws and regulations governing waste management. The federal Resource Conservation and Recovery Act of 1976 contains comprehensive requirements for the handling of solid and hazardous wastes. The generation of electricity
produces non-hazardous and hazardous materials, and we incur substantial costs to store and dispose of waste materials. The EPA and the states in which we operate coal-fired units may develop new regulations that impose additional requirements on
facilities that store or dispose of fossil fuel combustion materials, including types of coal ash. If so, we may be required to change the current waste



19

##### Table of Contents

management practices at some facilities and incur additional costs for increased waste management requirements. The MDE has proposed new regulations to
govern the disposal of coal ash and we expect these regulations to become final in 2008. We do not expect any significant effect on the operations of our coal ash disposal facilities as a result of these new regulations.

Additionally, CERCLA, also known as the Superfund law, establishes a federal framework for dealing with the cleanup of contaminated sites. Many states
have enacted similar state superfund statutes as well as other laws imposing obligations to investigate and clean up contamination. Our Pittsburg, Contra Costa and Potrero facilities have areas of soil and groundwater contamination subject to CERCLA
and the California Health and Safety Code. Prior to our acquisition of those facilities from PG&E in 1998, PG&E conducted soil and groundwater investigations at those facilities which revealed contamination. The consultants conducting the
investigation estimated the aggregate cleanup costs at those facilities could be as much as $60 million. Pursuant to the terms of the Purchase and Sale Agreement with PG&E, PG&E has responsibility for the containment or capping of all
soil and groundwater contamination and the disposition of up to 60,000 cubic yards of contaminated soil from the Potrero generating facility and the remediation of any groundwater or solid contamination identified at the Pittsburg and Contra Costa
generating facilities, in each case with respect to contamination existing at those facilities in 1999 when they were purchased by our subsidiaries. Pursuant to our requests, PG&E has disposed of 807 cubic yards of contaminated soil from the
Potrero generating facility. We are not aware of soil or groundwater conditions for which we expect remediation costs to be material that are not the responsibility of other parties.

|Item 1A. | Risk Factors
|-------- | ------------

The following
are factors that could affect our future performance:

Our revenues are unpredictable because most of our facilities operate without long-term power
sales agreements, and our revenues and results of operations depend on market and competitive forces that are beyond our control.

We sell capacity, energy and ancillary services from most of our generating facilities into competitive power markets on a short-term fixed price basis or through power sales agreements. Since mid-2007, our revenues from selling capacity
have become a significant part of our overall revenues. We are not guaranteed recovery of our costs or any return on our capital investments through mandated rates. The market for wholesale electric energy and energy services reflects various market
conditions beyond our control, including the balance of supply and demand, the marginal and long run costs incurred by our competitors and the effect of market regulation. Being concentrated in a few geographic markets results in concentrated
exposure to those markets, especially PJM. The price for which we can sell our output may fluctuate on a day-to-day basis. The markets in which we compete remain subject to one or more forms of regulation that limit our ability to raise prices
during periods of shortage to the degree that would occur in a fully deregulated market and may thereby limit our ability to recover costs and an adequate return on our investment. Our revenues and results of operations are influenced by factors
that are beyond our control, including:



| |  |  | the failure of market regulators to develop and maintain efficient mechanisms to compensate merchant generators for the value of providing capacity needed to meet
demand;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | actions by regulators, ISOs, RTOs and other bodies that may prevent capacity and energy prices from rising to the level necessary for recovery of our costs, our
investment and an adequate return on our investment;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | legal and political challenges to the rules used to calculate capacity payments in the markets in which we operate;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | the possibility that appellate courts considering the pending appeals of the FERCs rulings that approved the RPM and FCM tariffs do not affirm the FERCs
approval of those tariffs, resulting in modifications to the capacity payments made under those tariffs in the future and possibly refunds for past periods;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the ability of wholesale purchasers of power to make timely payment for energy or capacity, which may be adversely affected by factors such as retail rate caps,
refusals by regulators to allow utilities to recover fully their wholesale power costs and investments through rates, catastrophic losses and losses from investments by utilities in unregulated businesses;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the fact that increases in prevailing market prices for fuel oil, coal, natural gas and emissions allowances may not be reflected in prices we receive for sales of
energy;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | increases in supplies due to actions of our current competitors or new market entrants, including the development of new generating facilities or alternative energy
sources that may be able to produce electricity less expensively than our generating facilities and improvements in transmission that allow additional supply to reach our markets;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | decreases in energy consumption resulting from demand-side management programs such as automated demand response, which may alter the amount and timing of consumer
energy use;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the competitive advantages of certain competitors including continued operation of older power plants in strategic locations after recovery of historic capital
costs from ratepayers;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | existing or future regulation of our markets by the FERC, ISOs and RTOs, including any price limitations and other mechanisms to address some of the price
volatility or illiquidity in these markets or the physical stability of the system;

In addition, unlike most other commodities, electric energy can only be stored on a very limited basis and
generally must be produced at the time of use. As a result, the wholesale power markets are subject to substantial price fluctuations over relatively short periods of time and can be unpredictable.

Changes in commodity prices may negatively affect our financial results by increasing the cost of producing power or lowering the price at which we are able to
sell our power.

Our generating business is subject to changes in power prices and fuel costs, and these commodity prices are
influenced by many factors outside of our control, including weather, market liquidity, transmission and transportation inefficiencies, availability of competitively priced alternative energy sources, demand for energy commodities, production of
natural gas, crude oil and coal, natural disasters, wars, embargoes and other catastrophic events, and federal, state and environmental regulation and legislation. Significant fluctuations in commodity prices may affect our financial results and
financial position by increasing the cost of producing power and decreasing the amounts we receive from the sale of power.

Our use of derivative
contracts in our asset management activities will not fully protect us from fluctuations in commodity prices and our risk management policy cannot eliminate the risks associated with these activities.

We engage in asset management activities related to sales of electricity and purchases of fuel. The income and losses from these activities are recorded
as operating revenues and fuel costs. We may use forward contracts and other derivative financial instruments to manage market risk and exposure to volatility in prices of electricity, coal, natural gas, emissions and oil. We cannot provide
assurance that these strategies will be successful in managing our price risks, or that they will not result in net losses to us as a result of future volatility in electricity, fuel and emissions markets. Actual power prices and fuel costs may
differ from our expectations.

Our asset management activities include natural gas derivative instruments that we use to hedge power prices
for our baseload generation. The effectiveness of these hedges is dependent upon the correlation between power and natural gas prices in the markets where we operate. If those prices are not sufficiently correlated, our financial results and
financial position could be adversely affected.

Additionally, we expect to have an open position in the market, within our established
guidelines, resulting from the management of our portfolio. To the extent open positions exist, fluctuating commodity prices can affect our financial results and financial position, either favorably or unfavorably. Furthermore, the risk management
procedures we have in place may not always be followed or may not always work as planned. Unauthorized hedging and related activities by our employees could result in significant penalties and financial losses. As a result of these and other
factors, we cannot predict the outcome that risk management decisions may have on our businesses, operating results or financial position. Although management devotes a considerable amount of attention to these issues, their outcome is uncertain.

We are exposed to the risk of fuel and fuel transportation cost increases and volatility and interruption in fuel supply because our facilities
generally do not have long-term agreements for the supply of natural gas, coal and oil.

Although we attempt to purchase fuel based
on our expected fuel requirements, we still face the risks of supply interruptions and fuel price volatility. Our cost of fuel may not reflect changes in energy and fuel prices in part because we must pre-purchase inventories of coal and oil for
reliability and dispatch requirements, and thus



23

##### Table of Contents

the price of fuel may have been determined at an earlier date than the price of energy generated from it. The price we can obtain from the sale of energy may
not rise at the same rate, or may not rise at all, to match a rise in fuel costs. This may have a material adverse effect on our financial performance. The volatility of fuel prices could adversely affect our financial results and operations.

Our asset management and proprietary trading activities may increase the volatility of our quarterly and annual financial results.

We engage in asset management activities to hedge economically our exposure to market risk with respect to: (1) electricity
sales from our generating facilities; (2) fuel used by those facilities; and (3) emissions allowances. We generally attempt to balance our fixed-price purchases and sales commitments in terms of contract volumes and the timing of
performance and delivery obligations through the use of financial and physical derivative contracts. We also use derivative contracts with respect to our limited proprietary trading and fuel oil management activities, through which we attempt to
achieve incremental returns by transacting where we have specific market expertise. Derivatives from our asset management and proprietary trading activities are recorded on our balance sheet at fair value pursuant to SFAS 133. None of our
derivatives recorded at fair value are designated as hedges under SFAS 133 and changes in their fair values are therefore recognized currently in earnings as unrealized gains or losses. As a result, our financial resultsincluding gross margin,
operating income and balance sheet ratioswill, at times, be volatile and subject to fluctuations in value primarily due to changes in forward electricity and fuel prices. For a more detailed discussion of the accounting treatment of our asset
management and proprietary trading activities, see Note 4 to our consolidated and combined financial statements contained elsewhere in this report.

Operation of our generating facilities involves risks that may have a material adverse effect on our cash flows and results of operations.

The operation of our generating facilities involves various operating risks, including, but not limited to:



| |  |  | the output and efficiency levels at which those generating facilities perform;
| | - |  | ------------------------------------------------------------------------------



| |  |  | interruptions in fuel supply;
| | - |  | -----------------------------



| |  |  | disruptions in the delivery of electricity;
| | - |  | -------------------------------------------

A decrease in, or the elimination of, the revenues generated by our facilities or an increase in the
costs of operating such facilities could materially affect our cash flows and results of operations, including cash flows available to us to make payments on our debt or our other obligations.

Our operating results are subject to quarterly and seasonal fluctuations.

Our operating results have fluctuated in the past and may continue to do so in the future as a result of a number of factors, including seasonal variations in demand and fuel prices.

We compete to sell energy and capacity in the wholesale power markets against some competitors that enjoy competitive advantages, including the ability to recover
fixed costs through rate base mechanisms and a lower cost of capital.

Regulated utilities in the wholesale markets generally enjoy
a lower cost of capital than we do and often are able to recover fixed costs through regulated retail rates including, in many cases, the costs of generation, allowing them to build, buy and upgrade generating facilities without relying exclusively
on market clearing prices to recover their investments. The competitive advantages of such participants could adversely affect our ability to compete effectively and could have an adverse impact on the revenues generated by our facilities.

Our business and activities are subject to extensive environmental requirements and could be adversely affected by such requirements, including
future changes to them.

Our business is subject to extensive environmental regulations promulgated by federal, state and local
authorities, which, among other things, restrict the discharge of pollutants into the air, water and soil, and also govern the use of water from adjacent waterways. Such laws and regulations frequently require us to obtain operating permits and
remain in continuous compliance with the conditions established by those operating permits. To comply with these legal requirements and the terms of our operating permits, we must spend significant sums on environmental monitoring, pollution control
equipment and emissions allowances. If we were to fail to comply with these requirements, we could be subject to civil or criminal liability and the imposition of liens or fines. We may be required to shut down facilities if we are unable to comply
with the requirements, or if we determine the expenditures required to comply are uneconomic.

From time to time we may not be able to
obtain necessary environmental regulatory approvals. Such approvals could be delayed or subject to onerous conditions. If there is a delay in obtaining environmental regulatory approval or if onerous conditions are imposed, the operation of our
generating facilities or the sale of electricity to third parties could be prevented or become subject to additional costs. Such delays or onerous conditions could have a material adverse effect on our financial performance and condition.

In addition, environmental laws, particularly with respect to air emissions, wastewater discharge and cooling water systems, are generally
becoming more stringent, which may require us to make expensive facility upgrades or restrict our operations. With the trend toward stricter standards, greater regulation and more extensive permitting requirements, we expect our environmental
expenditures to be substantial in the future. Although we have budgeted for significant expenditures to comply with these requirements, actual expenditures may be greater than budgeted amounts. We may have underestimated the cost of the
environmental work we are planning or the air emissions allowances we anticipate buying. In addition, new environmental laws may be enacted, new or revised regulations under those laws may be issued, the interpretation of such laws and regulations
by regulatory authorities or the courts may change, or additional information concerning the way in which such requirements apply to us may be identified. For example, in April 2006, Maryland enacted the Healthy Air Act, which requires more
significant reductions in emissions of NOx, SO2 and mercury than the CAIR. This legislation affects our coal-fired units at Chalk Point, Dickerson and Morgantown. We anticipate that the total capital expenditures to achieve compliance for SO2 and
NOx emissions at these facilities will be approximately $1.6 billion through the first quarter of 2010.

Increased public concern and growing political pressure related to global warming has resulted in
significant increases in the regulation of greenhouse gases, including CO2 at the state level. Future local, state and federal regulation of greenhouse gases are likely to create substantial environmental costs for us in the form of taxes or
purchases of emissions allowances. Many of the states where we own generating facilities, including California, Maryland, Massachusetts and New York, have recently committed to mandatory reductions in statewide CO2 emissions through a regional
cap-and-trade program. Some of these programs include proposals that would not allocate emissions allowances to existing sources of emissions and instead require all allowances to be purchased initially through an auction process. This could
decrease the amount of available allowances and substantially increase their prices. Because our generating facilities emit CO2, these regulations and similar future laws may significantly increase our operating costs.

Certain environmental laws, including CERCLA and comparable state laws, impose strict and, in many circumstances, joint and several liability for costs
of remediating contamination in soil, groundwater and elsewhere. Some of our facilities have areas with known soil and/or groundwater contamination. Releases of hazardous substances at our generating facilities, or at locations where we dispose of
(or in the past disposed of) hazardous substances and other waste, could require us to spend significant sums to remediate contamination, regardless of whether we caused such contamination. The discovery of significant contamination at our
generating facilities, at disposal sites we currently use or have used, or at other locations for which we may be liable, or the failure or inability of parties contractually responsible to us for contamination to respond when claims or obligations
regarding such contamination arise, could have a material adverse effect on our financial performance and condition.

Major environmental
construction projects planned by 2010 at our Mid-Atlantic coal facilities may not meet their anticipated schedule, which would restrict these units from running at their maximum economic levels. In the event that the operating constraints were
sufficiently severe, Mirant Mid-Atlantic may not have sufficient cash flow to permit it to make distributions or, if more severe, to meet its obligations.

Under the Maryland Healthy Air Act, we are required to reduce annual emissions below certain levels by January 2010. The levels established do not allow for the use of emissions allowances to meet the mandated
levels. To meet these requirements, we are installing pollution control equipment on all of our Maryland coal facilities. We may not meet this construction schedule by January 2010 due to a number of factors, including:



| |  |  | failure or delays in obtaining necessary permits and approvals;
| | - |  | ---------------------------------------------------------------



| |  |  | adverse weather conditions;
| | - |  | ---------------------------



| |  |  | unanticipated cost increases;
| | - |  | -----------------------------



| |  |  | engineering problems;
| | - |  | ---------------------



| |  |  | shortages of equipment, materials or skilled labor;
| | - |  | ---------------------------------------------------



| |  |  | unscheduled delays in delivery of materials and equipment; and
| | - |  | --------------------------------------------------------------



| |  |  | work stoppages.
| | - |  | ---------------

Any of these
factors may significantly increase the estimated costs of our environmental construction projects or result in a loss of cash flows from operations due to reduced unit operations.

The expected decommissioning and/or site remediation obligations of certain of our generating facilities may negatively affect our cash flows.

We expect that certain of our generating facilities and related properties will become subject to decommissioning and/or site remediation obligations
that may require material expenditures. For example, we may start decommissioning the Lovett facility if the final operating unit ceases operation on April 19, 2008. We expect the decommissioning of the Lovett facility to cost approximately $20
million. The exact amount and timing of such expenditures is not presently known. Furthermore, laws and regulations may change to impose



26

##### Table of Contents

material additional decommissioning and remediation obligations on us in the future. If we are required to make material expenditures to decommission or
remediate one or more of our facilities, such obligations will affect our cash flows and may adversely affect our ability to make payments on our obligations.

Our consolidated indebtedness could adversely affect our ability to raise additional capital to fund our operations, limit our ability to react to changes in the economy or our industry and prevent us from meeting or refinancing our
obligations.

As of December 31, 2007, our consolidated indebtedness was $3.093 billion. In addition, the present value of
lease payments under the Mirant Mid-Atlantic leveraged leases is approximately $1 billion (assuming a 10% discount rate) and the termination value of the Mirant Mid-Atlantic leveraged leases is $1.4 billion. Our leverage could have important
consequences, including the following: (1) it may limit our ability to obtain additional debt or equity financing for working capital, capital expenditures, debt service requirements, acquisitions and general corporate or other purposes;
(2) a substantial portion of our cash flows from operations must be dedicated to the payment of principal and interest on our indebtedness and will not be available for other purposes, including our operations, capital expenditures and future
business opportunities; (3) the debt service requirements of our indebtedness could make it more difficult for us to satisfy or refinance our financial obligations; (4) borrowings under Mirant North Americas senior secured credit
facilities are at variable rates of interest, exposing us to the risk of increased interest rates; (5) it may limit our ability to adjust to changing market conditions and place us at a competitive disadvantage compared with our competitors
that have less debt; and (6) we may be more vulnerable in a downturn in general economic conditions or in our business and we may be unable to carry out capital expenditures that are important to our long-term growth or necessary to comply with
environmental regulations.

The sale by our parent of the six U.S. natural gas-fired facilities and its Philippine and Caribbean
businesses, and its decision to return a total of $4.6 billion in excess cash to its stockholders, could adversely limit its ability to make capital contributions to or otherwise support us and our subsidiaries.

We and our subsidiary, Mirant North America, are holding companies and we may not have access to sufficient cash to meet our obligations if our subsidiaries, in
particular, Mirant Mid-Atlantic, are unable to make distributions.

We and our subsidiary, Mirant North America, are holding
companies and, as a result, we are dependent upon dividends, distributions and other payments from our operating subsidiaries to generate the funds necessary to meet our obligations. In particular, a significant portion of cash from our operations
is generated by the power generating facilities of Mirant Mid-Atlantic. Under the Mirant Mid-Atlantic leveraged leases, Mirant Mid-Atlantic is subject to a covenant that restricts its right to make distributions to its immediate parent, Mirant North
America. In turn, Mirant North America is subject to covenants that restrict its ability to make distributions to us. The ability of Mirant North America and Mirant Mid-Atlantic to satisfy the criteria set forth in their respective debt covenants in
the future could be impaired by factors which negatively affect the performance of the power generating facilities of Mirant Mid-Atlantic, including interruptions in operation or curtailment of operations to comply with environmental restrictions.

Our obligations and the obligations of Mirant North America, including our respective indebtedness, are effectively subordinated to the
obligations or indebtedness of our respective subsidiaries, including the Mirant Mid-Atlantic leveraged leases.

We may be unable to generate
sufficient liquidity to service our debt and to post required amounts of cash collateral necessary to hedge market risk effectively.

Our ability to pay principal and interest on our debt depends on our future operating performance. If our cash flows and capital resources are insufficient to allow us to make scheduled payments on our debt, we may have to reduce or delay
capital expenditures, sell assets, seek additional capital, restructure or refinance. There

can be no assurance that the terms of our debt will allow these alternative measures, that the financial markets will be available to us on acceptable terms
or that such measures would satisfy our scheduled debt service obligations.

We seek to manage the risks associated with the volatility in
the price at which we sell power produced by our generating facilities and in the prices of fuel, emissions allowances and other inputs required to produce such power by entering into hedging transactions. These asset management activities may
require us to post collateral either in the form of cash or letters of credit. As of December 31, 2007, we had approximately $108 million of posted cash collateral and $290 million of letters of credit outstanding primarily to support our asset
management activities, debt service reserve requirements and other commercial arrangements. See Note 9 to our consolidated and combined financial statements contained elsewhere in this report for further information on our posted cash collateral and
letters of credit. While we seek to structure transactions in a way that reduces our potential liquidity needs for collateral, we may be unable to execute our hedging strategy successfully if we are unable to post the amount of collateral required
to enter into and support hedging contracts.

We are an active participant in energy exchange and clearing markets. These markets require a
per contract initial margin to be posted, regardless of the credit quality of the participant. The initial margins are determined by the exchanges through the use of proprietary models that rely on a variety of inputs and factors, including market
conditions. We have limited notice of any changes to the margin rates. Consequently, we are exposed to changes in the per unit margin rates required by the exchanges and could be required to post additional collateral on short notice.

If our facilities experience unplanned outages, we may be required to procure replacement power in the open market to satisfy contractual commitments.
Without adequate liquidity to post margin and collateral requirements, we may be exposed to significant losses and may miss significant opportunities, and we may have increased exposure to the volatility of spot markets.

Our business is subject to complex government regulations. Changes in these regulations, or their administration, by legislatures, state and federal regulatory
agencies, or other bodies may affect the costs of operating our facilities or our ability to operate our facilities. Such cost impacts, in turn, may negatively affect our financial condition and results of operations.

We are subject to regulation by the FERC regarding the terms and conditions of wholesale service and rates, as well as by state agencies regarding
physical aspects of our generating facilities. The majority of our generation is sold at market prices under market based rate authority granted by the FERC. If certain conditions are not met, the FERC has the authority to withhold or rescind market
based rate authority and require sales to be made based on cost-of-service rates. A loss of our market based rate authority could have a materially negative impact on our generating business.

Even where market based rate authority has been granted, the FERC may impose various forms of market mitigation measures, including price caps and
operating restrictions, where it determines that potential market power might exist and that the public interest requires such potential market power to be mitigated. In addition to direct regulation by the FERC, most of our facilities are subject
to rules and terms of participation imposed and administered by various RTOs and ISOs. Although these entities are themselves ultimately regulated by the FERC, they can impose rules, restrictions and terms of service that are quasi-regulatory
in nature and can have a material adverse impact on our business. For example, ISOs and RTOs may impose bidding and scheduling rules, both to curb the potential exercise of market power and to ensure market functions. Such actions may materially
affect our ability to sell and the price we receive for our energy and capacity.

To conduct our business, we must obtain and periodically
renew licenses, permits and approvals for our facilities. These licenses, permits and approvals can be in addition to any required environmental permits. No assurance can be provided that we will be able to obtain and comply with all necessary
licenses, permits and



28

##### Table of Contents

approvals for these facilities. If we cannot comply with all applicable regulations, our business, results of operations and financial condition could be
adversely affected.

On August 8, 2005, the EPAct 2005 was enacted. Among other things, the EPAct 2005 provides incentives for various
forms of electric generating technologies, which will subsidize certain of our competitors. Regulations that could be issued pursuant to the EPAct 2005 may have an adverse impact on our business.

We cannot predict whether the federal or state legislatures will adopt legislation relating to the restructuring of the energy industry. There are
proposals in many jurisdictions both to advance and to roll back the movement toward competitive markets for the supply of electricity, at both the wholesale and retail levels. In addition, any future legislation favoring large, vertically
integrated utilities and a concentration of ownership of such utilities could affect our ability to compete successfully, and our business and results of operations could be adversely affected. We cannot provide assurance that the introductions of
new laws, or other future regulatory developments, will not have a material adverse impact on our business, operations or financial condition.

Changes in technology may significantly affect our generating business by making our generating facilities less competitive.

We generate electricity using fossil fuels at large central facilities. This method results in economies of scale and lower costs than newer technologies such as fuel cells, microturbines, windmills and photovoltaic solar cells. It is
possible that advances in those technologies will reduce their costs to levels that are equal to or below that of most central station electricity production, which could have a material adverse effect on our results of operations.

Terrorist attacks, future war or risk of war may adversely affect our results of operations, our ability to raise capital or our future growth.

As power generators, we face heightened risk of an act of terrorism, either a direct act against one of our generating facilities or an inability to
operate as a result of systemic damage resulting from an act against the transmission and distribution infrastructure that we use to transport our power. If such an attack were to occur, our business, financial condition and results of operations
could be materially adversely affected. In addition, such an attack could affect our ability to service our indebtedness, our ability to raise capital and our future growth opportunities.

Our operations are subject to hazards customary to the power generating industry. We may not have adequate insurance to cover all of these hazards.

Our operations are subject to many hazards associated with the power generating industry, which may expose us to significant
liabilities for which we may not have adequate insurance coverage. Power generation involves hazardous activities, including acquiring, transporting and unloading fuel, operating large pieces of rotating equipment and delivering electricity to
transmission and distribution systems. In addition to natural risks, such as earthquake, flood, lightning, hurricane and wind, hazards, such as fire, explosion, collapse and machinery failure, are inherent risks in our operations. These hazards can
cause significant injury to personnel or loss of life, severe damage to and destruction of property, plant and equipment, contamination of, or damage to, the environment and suspension of operations. The occurrence of any one of these events may
result in our being named as a defendant in lawsuits asserting claims for substantial damages, environmental cleanup costs, personal injury and fines and/or penalties. We maintain an amount of insurance protection that we consider adequate, but we
cannot assure that our insurance will be sufficient or effective under all circumstances and against all hazards or liabilities to which we may be subject. A successful claim for which we are not fully insured could have a material adverse effect on
our financial results and our financial condition.

|Item 7. | Managements Discussion and Analysis of Results of Operations and Financial Condition
|------- | -------------------------------------------------------------------------------------

This section is intended to provide the reader with information that will assist in understanding our financial statements, the changes in those
financial statements from year to year and the primary factors contributing to those changes. The following discussion should be read in conjunction with our consolidated and combined financial statements and the notes accompanying those financial
statements.

Overview

We are a
competitive energy company that produces and sells electricity. We are an indirect wholly-owned subsidiary of Mirant. We own or lease 10,280 MW of electric generating capacity located in markets in the Mid-Atlantic and Northeast regions and in
California. We also operate an integrated asset management and energy marketing organization based in Atlanta, Georgia.

Dispositions

In the third quarter of 2006, Mirant commenced auction processes to sell six U.S. natural gas-fired facilities including our
indirectly owned Zeeland and Bosque facilities. On May 1, 2007, we completed the sale of the Zeeland and Bosque natural gas-fired facilities. In addition, on May 7, 2007, we completed the sale of Mirant NY-Gen, an indirect wholly-owned
subsidiary. In accordance with Mirant North Americas debt covenants, approximately $524 million of the proceeds from the sale of the Zeeland and Bosque facilities are being reinvested in the business of Mirant North America. At
December 31, 2007, $273 million of such proceeds have been reinvested in Mirant North America. See Note 10 to our consolidated and combined financial statements contained elsewhere in this report for additional information regarding the
accounting for these facilities as discontinued operations.

Exploration of Strategic Alternatives and Share Repurchases

On April 9, 2007, Mirant announced that its Board of Directors had decided to explore strategic alternatives to enhance stockholder value. In the
exploration process, the Board of Directors considered whether the interests of stockholders would be best served by returning excess cash from the sale proceeds to stockholders, with Mirant continuing to operate its retained businesses or,
alternatively, whether greater stockholder value would be achieved by entering into a transaction with another company, including a sale of Mirant in its entirety. On November 9, 2007, Mirant announced the conclusion of the strategic review
process. Mirant plans to return a total of $4.6 billion of excess cash to its stockholders.

Hedging Activities

We economically hedge a substantial portion of our Mid-Atlantic coal-fired baseload generation and certain of our Northeast coal, gas
and oil-fired generation through OTC transactions. A significant portion of our hedges are financial swap transactions that are senior unsecured obligations of Mirant Mid-Atlantic and do not require the posting of cash collateral either for initial
margin or for securing exposure as a result of changes in power prices. However, we generally do not hedge our intermediate and peaking units for tenors greater than 12 months. At February 25, 2008, we were economically hedged as follows:

Through December 31, 2007, we paid approximately $500 million for capital expenditures

Results of Operations

The following discussion of our performance is organized by reportable operating segment, which is consistent with the way we manage our business. In 2007, we completed the sale of the Zeeland and Bosque facilities
and Mirant NY-Gen. The sales have resulted in the reclassification of the revenues and expenses of these facilities to discontinued operations and the reclassification of the related assets and liabilities to assets held for sale for all periods
presented through their respective dates of sale.

In the tables below, the Mid-Atlantic region includes our Chalk Point, Morgantown,
Dickerson and Potomac River facilities. The Northeast region includes our Bowline, Canal, Lovett, Kendall and Marthas Vineyard facilities. The California region includes our Pittsburg, Contra Costa and Potrero facilities. Other Operations

Back-to-Back Agreement) and the transition power agreement with Pepco that expired in January 2005. See Note 15 to our consolidated and combined financial statements contained elsewhere in this report for further discussion of the
Back-to-Back Agreement. Other Operations also includes interest on our and Mirant North Americas debt and interest income on our invested cash balances.

Energy represents gross margin from the generation of electricity, sales and purchases of emissions
allowances, fuel sales, purchases and handling of fuel, steam sales and our proprietary trading and fuel oil management activities.

Contracted and capacity represents gross margin received from capacity sold in ISO administered capacity markets, through RMR contracts and ancillary services.

Incremental realized value of hedges represents the actual margin upon the settlement of our power and fuel hedging contracts.

Unrealized gross margin represents the net unrealized gain or loss on our derivative contracts.

Our gross
margin for the year ended December 31, 2007, was $1.002 billion as compared to $1.949 billion for the same period in 2006. The decrease in gross margin, which includes net unrealized gains and losses from our hedging activities, was principally
a result of the following:

A decrease of $1.233 billion in unrealized gross margin was comprised of the following:



| |  |  | unrealized losses of $624 million in 2007, which include $442 million from the settlement of power and fuel contracts during the period for which net unrealized
gains had been recorded in prior periods and a $182 million net decrease in the value of hedge contracts for future periods primarily related to increases in forward power prices in 2007; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | unrealized gains of $609 million in 2006, which include a $440 million net increase in the value of hedge contracts for future periods primarily related to
decreases in forward power prices in 2006 and $169 million from the settlement of power and fuel contracts during the period for which net unrealized losses had been recorded in prior periods.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

An increase of $286 million in realized gross margin primarily attributable to: (1) an increase in contracted and capacity of $231 million
principally related to the PJM RPM and the FCM in New England; (2) an increase in energy of $173 million as a result of an increase in power prices, a decrease in emissions prices, slightly higher generation volumes and the settlement of
favorable fuel oil management positions; partially offset by (3) a decrease of $118 million in incremental realized value of hedges.

The increase of $250 million in realized gross margin was principally a result of the
following:



| |  |  | an increase of $154 million in energy, primarily because of an increase in power prices, a decrease in emissions prices and slightly higher generation volumes;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an increase of $157 million in contracted and capacity related to higher capacity revenues from the PJM RPM, which became effective in June 2007. See
Item 1. Regulatory Environment for further discussion of RPM; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a decrease of $61 million in incremental realized value of hedges of our generation output primarily as a result of a decrease in the amount by which the
settlement value of power contracts exceeded market prices.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The decrease of $963 million in unrealized gross margin
was comprised of the following:



| |  |  | unrealized losses of $479 million in 2007, which include $270 million from the settlement of power and fuel contracts during the period for which net
unrealized gains had been recorded in prior periods and a $209 million net decrease in the value of hedge contracts for future periods primarily related to increases in forward power prices in 2007; and

The decrease of $6 million in realized gross margin was principally a result of the
following:



| |  |  | a decrease of $60 million in incremental realized value of hedges of our generation output, primarily as a result of a decrease in the amount by which the
settlement value of power contracts exceeded market prices;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an increase of $43 million in contracted and capacity from the implementation of the new FCM in New England. See Item 1. Regulatory Environment for
further information on the implementation of the new FCM; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an increase of $11 million in energy, primarily because of an increase in power prices and higher generation volumes.
| | - |  | ---------------------------------------------------------------------------------------------------------------------

The decrease of $104 million in unrealized gross margin was comprised of the following:



| |  |  | unrealized losses of $43 million in 2007, which include $57 million from the settlement of power and fuel contracts during the period for which unrealized
gains had been recorded in prior periods, partially offset by a $14 million net increase in the value of hedge contracts for future periods primarily related to decreases in forward power prices in 2007; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | unrealized gains of $61 million in 2006, which include a $50 million net increase in the value of hedge contracts for future periods primarily related to
decreases in forward power prices in 2006 and $11 million from the settlement of power and fuel contracts during the year for which unrealized losses had been recorded in prior periods, particularly during the high energy prices of late 2005.

Operating Expenses

Operating expenses increased $117 million primarily as a result of the following:



| |  |  | an increase of $63 million in operations and maintenance which included:
| | - |  | ------------------------------------------------------------------------



| |  |  | an increase of $71 million in 2007, which represents that portion of the 2006 New York property tax settlement that reduced operating expenses for 2006, but which
related to prior periods. See Note 15 to our consolidated financial statements contained elsewhere in this report for further discussion; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a decrease of $6 million related to a decrease in maintenance costs primarily as a result of the shutdown of Lovett units 3 and 4 in 2007 and repairs on Lovett
unit 5 in 2006.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an increase of $57 million in impairment losses. In 2007, we recorded an impairment loss of $175 million on our Lovett facility. In 2006, we recorded an
impairment loss of $118 million on the Bowline unit 3 suspended construction project. See Note 5 to our consolidated financial statements contained elsewhere in this report for additional information related to these impairments; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an increase of $3 million in gain on sales of assets, net which includes a $14 million gain on the sale of certain ancillary equipment that was included in the sale
of the six U.S. natural gas-fired facilities in the second quarter of 2007. This amount was partially offset by a decrease of $11 million in sales of

| | emissions allowances. In 2007, gain on the sales of emissions allowances was $33 million and included a gain of $22 million on the sales of excess emissions
allowances to third parties and $11 million related to the sales of emissions allowances to affiliates. In 2006, gain on the sales of emissions allowances to affiliates was $44 million. The affiliate gains are eliminated in the consolidated and
combined statements of operations.

The increase in our contracted and capacity gross margin and decrease in our energy gross margin
were primarily a result of the commencement of a new tolling agreement in the first quarter of 2007 at our Contra Costa and Pittsburg facilities. See Item 1. Business Segments for additional information regarding the tolling
agreement.

Operating Expenses

The
increase of $9 million in operating expenses includes an increase of $11 million in operations and maintenance expense in 2007, resulting from higher maintenance costs related to outages and a $5 million property tax settlement in 2006.

Other Expense (Income), Net

The decrease of $29 million in other expense (income), net is primarily a result of a gain of $26 million in 2006 related to the transfer of Contra Costa unit 8 to PG&E. See California Settlement in
Note 15 to our consolidated and combined financial statements contained elsewhere in this report for further discussion.

The decrease of $163 million in unrealized gross margin was comprised of the following:



| |  |  | in 2007, unrealized losses on proprietary trading and fuel oil management activities of $102 million, which include $115 million from the settlement of
power and fuel contracts during the period for which unrealized gains had been recorded in prior periods and a $13 million net increase in value associated with contracts for future periods; and

| |  |  | unrealized gains on proprietary trading and fuel oil management activities of $61 million in 2006.
| | - |  | --------------------------------------------------------------------------------------------------

The increase of $39 million in realized gross margin was principally a result of an increase in energy related to our proprietary trading and fuel oil
management activities as favorable positions entered into prior to 2007 were settled in the current period.

##### Table of Contents

Energy represents gross margin from the generation of electricity, sales and purchases of emissions
allowances, fuel sales, purchases and handling of fuel, steam sales and our proprietary trading and fuel oil management activities.

Contracted and capacity represents gross margin received from capacity sold in ISO administered capacity markets, through RMR contracts, ancillary services and from the Back-to-Back Agreement, which was terminated on August 10, 2007.

Incremental realized value of hedges represents the actual margin upon the settlement of our power and fuel hedging contracts.

Unrealized gross margin represents the unrealized gain or loss on our derivative contracts.

The significant increase in the gross margin for our Mid-Atlantic operations is primarily due to the following:



| |  |  | an increase of $581 million related to unrealized gross margin from hedging activities. In 2006, unrealized gains of $484 million are primarily due to
$312 million from increased value associated with forward power contracts for future periods as a result of decreases in forward power prices in 2006 and $172 million due to the settlement of power and fuel contracts during the year for which net
unrealized losses had been recorded in prior periods, particularly during the high energy prices of late 2005. In 2005, unrealized losses of $97 million were primarily due to increases in power prices as a result of increases in gas prices;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an increase of $545 million in incremental realized value of hedges of our generation output. In 2006, the incremental realized value of our hedges contributed
$263 million to our gross margin as our power contracts settled at prices higher than market prices for the year. In 2005, our opportunity cost of hedging was $282 million primarily due to the impact of rising energy prices in the latter part of
2005 that resulted in the settlement of power contracts at prices lower than market prices for that year; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a decrease of $238 million in energy primarily related to lower power prices and lower generation volumes on our oil-fired units. Power prices were lower due
to significantly lower gas prices in 2006 compared to 2005. Our baseload coal units generation decreased slightly and our 9% total decrease in generation volumes was driven by significantly lower volumes generated by our oil-fired units. A
sharp decrease in power prices combined with average oil prices that were somewhat higher than in 2005 resulted in our oil-fired units not being able to dispatch economically for much of the year.

The increase in gross margin is primarily due to the following:



| |  |  | an increase of $72 million related to unrealized gross margin from hedging activities. In 2006, unrealized gains of $61 million are primarily due to $50
million from increased value associated with forward power and fuel contracts for future periods mainly as a result of decreases in forward power prices in 2006 and $11 million due to the settlement of power and fuel contracts during the year for
which unrealized losses had been recorded in prior periods, particularly during the high energy prices of late 2005. In 2005, unrealized losses of $11 million were primarily due to increases in power prices as a result of increased gas prices and
the settlement of contracts during the year for which unrealized losses had been recorded in prior periods, partially offset by an increase in the value of fuel hedges due to higher fuel prices;

| |  |  | an increase of $168 million in incremental realized value of hedges of our generation output. In 2006, the incremental realized value of our hedges contributed
$125 million to our gross margin as our power contracts settled at prices higher than market prices for the year, partially offset by hedged fuel costs

| | that were higher than the market. In 2005, our opportunity cost of hedging was $43 million primarily due to the impact of rising energy prices in the latter
part of 2005 that resulted in the settlement of power contracts at prices lower than market prices for that year, partially offset by the favorable impact of hedged fuel costs that were generally lower than the market as fuel prices increased in
2005; and

| |  |  | a decrease of $97 million in energy primarily related to lower generation volumes. Our decrease in generation volumes was driven by significantly lower volumes
generated by our oil-fired units. A decrease in power prices combined with average oil prices that were higher than in 2005 resulted in our oil-fired units not being able to dispatch economically for most of the period.

Operating Expenses

The decrease of $20 million
in operating expenses is primarily due to a decrease of $94 million in operations and maintenance, which relates to the New York property tax settlement. Of this amount, $71 million relates to periods prior to 2006. The remaining decrease in
property tax expense represents the difference in the 2006 expense under the settlement compared to the 2005 expense that was accrued based on the property tax assessments. Gains on sales of assets increased $36 million due to an increase of
$37 million in gains on sales of emissions allowances to affiliates that are eliminated in the consolidated statement of operations. Impairment losses in 2006 represent the impairment of the Bowline unit 3 suspended construction project.

##### Table of Contents

The increase in our energy gross margin is primarily due to several days of extreme heat in
July 2006, which allowed us to earn incremental gross margin on units that were under a tolling agreement for the same period in 2005. The expiration of this tolling agreement is the primary reason for the decrease in our contracted and
capacity margin.

Other Expense (Income), net

The decrease of $35 million in other expense (income), net is primarily due to a gain of $26 million in 2006 related to the transfer of Contra Costa unit 8 to PG&E and an increase of $6 million in interest income. See California
Settlement in Note 15 to our consolidated and combined financial statements contained elsewhere in this report for further discussion.

Other
Operations

Other Operations includes proprietary trading, fuel oil management and for periods prior to 2006, gains and losses
related to the Back-to-Back Agreement and the transition power agreement with Pepco that expired in January 2005. See Pepco Litigation in Note 15 to our consolidated and combined financial statements contained elsewhere in this report
for further discussion of the Back-to-Back Agreement. The following table summarizes the operations of our Other Operations segment for the years ended December 31, 2006 and 2005 (in millions):

##### Table of Contents

The increase in gross margin is primarily due to the following:



| |  |  | an increase of $31 million in energy, primarily related to our proprietary trading and fuel oil management activities net of cost or market adjustments on our oil
inventory during the third and fourth quarters of 2006;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an increase of $78 million in contracted and capacity due to a decrease in realized losses on the Back-to-Back Agreement and the hedges related to this contract,

| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a decrease of $24 million in unrealized gross margin, which includes an increase of $73 million in unrealized gains on our proprietary trading and fuel oil
management activities, offset by a decrease of $97 million in unrealized gains on the Back-to-Back Agreement and the related hedges. In 2006, the Back-to-Back agreement was transferred to Mirant Power Purchase.

Estimated claims and losses on rejected and amended contracts relate primarily to rejected energy
contracts, such as tolling agreements, gas transportation contracts and electric transmission contracts.

Discontinued Operations

During the third quarter of 2006, Mirant commenced auction processes to sell six U.S. natural gas-fired facilities, including the Zeeland and Bosque
facilities. Accordingly, the results of operations related to the planned sales were reclassified to income (loss) from discontinued operations in our consolidated and combined statements of operations for all periods presented.

For the year ended December 31, 2006, we reported net income from discontinued operations of $3 million, which includes an impairment loss to
write-down the Zeeland and Bosque facilities to fair value. For the year ended December 31, 2005, we reported a net loss of $9 million. See Note 10 to our consolidated and combined financial statements contained elsewhere in this report
for additional information related to discontinued operations.

Liquidity and Capital Resources

Sources of Funds and Capital Structure

The principal sources of liquidity for our future
operations and capital expenditures are expected to be: (1) existing cash on hand and cash flows from the operations of our subsidiaries; (2) letters of credit issued or borrowings made under Mirant North Americas $800 million
senior secured revolving credit facility; (3) $200 million of letter of credit capacity available under the Mirant North America senior secured term loan; and (4) redemptions of preferred shares in Mirant Americas.

##### Table of Contents

We and our subsidiary, Mirant North America, are holding companies. Except for existing cash on hand and,
in the case of Mirant North America, letters of credit and borrowings under its senior credit facilities, the liquidity of Mirant Americas Generation and Mirant North America is dependent on the distributions and dividends of their subsidiaries and
their ability to refinance. The chart below is a summary representation of our capital structure and is not a complete organizational chart.

LOGO

A significant portion of cash from our operations is generated by the power generation facilities of Mirant
Mid-Atlantic. Under the Mirant Mid-Atlantic leveraged leases, Mirant Mid-Atlantic is subject to a covenant that restricts its right to make distributions to Mirant North America. Mirant Mid-Atlantics ability to satisfy the criteria set by that
covenant in the future could be impaired by factors which negatively affect the performance of its power generation facilities, including interruptions in operation or curtailment of operations to comply with environmental restrictions.

Our subsidiary Mirant North America is an intermediate holding company that is the parent of our operating subsidiaries, including Mirant
Mid-Atlantic. Mirant North America incurred certain indebtedness pursuant to its senior notes and senior secured credit facilities secured by the assets of Mirant North America and its subsidiaries (other than Mirant Mid-Atlantic and its
subsidiaries and Mirant Energy Trading). The indebtedness of Mirant North America includes certain covenants typical in such notes and credit facilities, including restrictions on dividends, distributions and other restricted payments. Further, the
notes and senior secured credit facilities include financial covenants that will exclude from the calculation the financial results of any subsidiary that is unable to make distributions or dividends at the time of such calculation. Thus, the
ability of Mirant Mid-Atlantic to make distributions to Mirant North America under the leveraged lease transaction could have a material effect on the calculation of the financial covenants under the senior notes and senior secured credit facilities
of Mirant North America and on its ability to make distributions to us.

At December 31, 2007, Mirant North America had distributed to
us all available cash that was permitted to be distributed under the terms of its debt agreements, leaving Mirant North America and its subsidiaries with $697 million. Of this amount, $242 million was held by Mirant Mid-Atlantic which, as
of December 31, 2007, met the ratio tests under the leveraged lease documents for distribution of the entire amount to Mirant North America. After taking into account the financial results of Mirant North America for the year ended
December 31, 2007, we expect Mirant North America will be able to distribute approximately $65 million to us in March 2008.

##### Table of Contents

Our ability to pay our obligations is dependent on the receipt of dividends from Mirant North America,
capital contributions from Mirant, redemptions under the Mirant Americas preferred shares and our ability to refinance all or a portion of those obligations as they become due.

Maintaining sufficient liquidity in our business is crucial in order to mitigate the risk of future financial distress to us. Accordingly, we plan on a
prospective basis for the expected liquidity requirements of our business considering the factors listed below:



| |  |  | expected expenditures with respect to maintenance activities and capital improvements, and related outages;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | expected collateral posted in support of our business;
| | - |  | ------------------------------------------------------



| |  |  | effects of market price volatility on the amount of collateral posted for economic hedge transactions and risk management transactions;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | effects of market price volatility on fuel pre-payment requirements;
| | - |  | --------------------------------------------------------------------



| |  |  | seasonal and intra-month working capital requirements; and
| | - |  | ----------------------------------------------------------



| |  |  | debt service obligations.
| | - |  | -------------------------

Our
operating cash flows may be affected by, among other things: (1) demand for electricity; (2) the difference between the cost of fuel used to generate electricity and the market value of the electricity generated; (3) commodity prices
(including prices for electricity, emissions allowances, natural gas, coal and oil); (4) the cost of ordinary course operations and maintenance expenses; (5) planned and unplanned outages; (6) terms with trade creditors; and
(7) cash requirements for capital expenditures relating to certain facilities (including those necessary to comply with environmental regulations).

Uses of Funds

Our requirements for liquidity and capital resources, other than for the day-to-day operation of our
generating facilities, are significantly influenced by the following activities: (1) capital expenditures required to keep our power generating facilities in operation; (2) debt service; (3) our asset management and proprietary
trading activities; and (4) the Mirant Mid-Atlantic operating leases.

Capital
Expenditures.Capital expenditures excluding capitalized interest for our continuing operations were $553 million, $127 million and $96 million for the years ended December 31, 2007, 2006 and
2005, respectively. Our capital expenditures for 2008, 2009 and 2010 are expected to be approximately $964 million, $516 million and $274 million, respectively. This forecast does not assume any construction of new generating units during the
forecast period. Instead, the current capital expenditure program, which is expected to be funded by cash on hand and operating cash flow, focuses on efficiency, safety, reliability and compliance with existing environmental laws and contract
obligations, including capital expenditures made to comply with the limitations for SO2 and NOx emissions under the Maryland Healthy Air Act. For a more detailed discussion of environmental expenditures we expect to incur in the future, see
Item 1. Business.

Debt Service.At December 31, 2007, we had $3.093 billion of
long-term debt with expected interest expense of approximately $237 million for 2008. In the fourth quarter of 2007, we purchased and retired $39 million of our senior notes due in 2011.

Under the terms of its senior secured term facility, Mirant North America is required to use 50% of its free cash flow for each fiscal year (less amounts
paid to us for the purpose of paying interest on our senior notes) to pay down its senior secured term loan, in addition to its scheduled amortization of $7 million per year. The percentage of free cash flow that Mirant North America is
required to use to pay down its senior secured term loan may be reduced to 25% upon the achievement by it of a net debt to EBITDA ratio of less than 2:1. At

##### Table of Contents

December 31, 2007, Mirant North Americas net debt to EBITDA was less than 2:1. As such, we were required to use 25% of our free cash flow to pay
down our senior secured term loan. We estimate this prepayment, which will be made during the first quarter of 2008, to be $132 million.

Mirant Mid-Atlantic Operating Leases.Mirant Mid-Atlantic leases the Morgantown and Dickerson baseload units and associated property through 2034 and 2029, respectively. Mirant Mid-Atlantic has an option
to extend the leases. Any extensions of the respective leases would be limited to 75% of the economic useful life of the facility, as measured from the beginning of the original lease term through the end of the proposed remaining lease term. We are
accounting for these leases as operating leases. While there is variability in the scheduled payment amounts over the lease term, we recognize rent expense for these leases on a straight-line basis. As of December 31, 2007, the total notional
minimum lease payments for the remaining term of the leases aggregated approximately $2.1 billion and the aggregate termination value for the leases was approximately $1.4 billion and generally decreases over time. Rent expense under the
Mirant Mid-Atlantic leases was $96 million for the years ended December 31, 2007 and 2006, and $99 million for the year ended December 31, 2005. In addition, Mirant Mid-Atlantic is required to post rent reserves in an aggregate amount
equal to the greater of the next six months rent, fifty percent of the next 12 months rent or $75 million.

Cash Collateral and Letters
of Credit.    In order to sell power and purchase fuel in the forward markets and perform other energy trading and marketing activities, we are often required to provide trade credit support to our counterparties or make
deposits with brokers. In addition, we are often required to provide cash collateral or letters of credit for access to the transmission grid, to participate in power pools, to fund debt service reserves and for other operating activities. Trade
credit support includes cash collateral, letters of credit and financial guarantees. In the event that we default, the counterparty can draw on a letter of credit or apply cash collateral held to satisfy the existing amounts outstanding under an
open contract. As of December 31, 2007, we had approximately $108 million of posted cash collateral and $290 million of letters of credit outstanding primarily to support our asset management activities, debt service and rent reserve
requirements and other commercial arrangements. Of the letters of credit outstanding at December 31, 2007, $199 million was posted by Mirant North America under its senior secured term loan and the remainder was issued under Mirant North
Americas $800 million senior secured revolving credit facility. Our liquidity requirements are highly dependent on the level of our hedging activity, forward prices for energy, emissions allowances and fuel, commodity market volatility and
credit terms with third parties. See Note 9 to our consolidated and combined financial statements contained elsewhere in this report for additional information.

The following table summarizes at December 31, 2007 and 2006, for our continuing operations, cash collateral posted with counterparties and brokers and letters of credit issued (in millions):

Operating leases are off-balance sheet arrangements. These amounts primarily relate to our minimum
lease payments associated with our lease of the Morgantown and Dickerson baseload units at our Mid-Atlantic facilities.

Fuel
commitments primarily relate to long-term coal agreements and other fuel purchase agreements. As of December 31, 2007, our total estimated fuel commitments were $506 million. In addition, we have transactions for which commercial terms have
been negotiated but for which contracts have not yet been executed. Individual transactions may or may not be binding prior to execution of a contract.

As of December 31, 2007, the total estimated commitments under LTSAs associated with turbines were approximately $31 million. These commitments are payable over the terms of the respective agreements, which
range from 10 to 20 years. These agreements have terms that allow for cancellation of the contracts by us upon the occurrence of certain events during the term of the contracts. Estimates for future commitments for the LTSAs are based on the stated
payment terms in the contracts at the time of execution. These payments are subject to an annual adjustment for inflation.

Other
represents open purchase orders less invoices received related to open purchase orders for general procurement of products and services purchased in the ordinary course of business. These include construction, maintenance and labor activities at our
generating facilities.

Maryland Healthy Air Act commitments are contracts and open purchase orders related to capital expenditures that we
will incur to comply with the limitations for SO2 and NOx emissions under the Maryland Healthy Air Act.

Long-term debt includes the
current portion of long-term debt and long-term debt on the consolidated balance sheets. Long-term debt also includes estimated interest on debt based on the U.S. Dollar LIBOR curve as of December 31, 2007.

2007 versus 2006

Continuing Operations

Operating Activities.    Our cash provided by operating activities is
affected by seasonality, changes in energy prices and fluctuations in our working capital requirements. Net cash provided by operating activities from continuing operations increased $304 million for the year ended December 31, 2007,
compared to 2006, primarily as a result of the following:



| |  |  | an increase in realized gross margin of $286 million for the year ended December 31, 2007, compared to 2006. See Results of Operations for
additional discussion of our performance in 2007 compared to 2006;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an increase of $745 million resulting from a reduction in bankruptcy related claims and expenses. In 2007, we paid $17 million in claims payable for the New
York entities and $3 million related to other Mirant Americas Generation claims. In 2006, we paid $1.755 billion of bankruptcy claims, of which $765 million was reflected in cash from operations;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an increase from the receipt in 2007 of a net refund of $48 million related to the New York property tax settlement, which is included in customer accounts
receivable, net in the consolidated statements of cash flows;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an increase of $18 million related to increases in net interest income as a result of higher cash balances resulting from the dispositions completed in 2007;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a decrease of $517 million as a result of changes in posted collateral levels which are included in funds on deposit in the consolidated statements of cash flows.
For the year ended December 31, 2007, we posted an additional $70 million of cash collateral primarily to support energy marketing activities. The change in collateral for the year ended December 31, 2006, provided a source of cash of $447
million primarily because of a decrease in cash collateral to support energy marketing activities of $592 million and a reduction of $56 million in cash collateral posted in connection with the Mirant Mid-Atlantic lease upon posting $75 million of
letters of credit. These amounts were partially offset by a use of cash as a result of the deposit of $200 million into a cash collateral account to support the issuance of letters of credit;

Critical Accounting Estimates

The accounting policies described below are considered critical to obtaining an understanding of our consolidated and combined financial statements because their application requires significant estimates and
judgments by management in preparing our consolidated and combined financial statements. Managements estimates and judgments are inherently uncertain and may differ significantly from actual results achieved. Management considers an accounting
estimate to be critical if the following conditions apply:



| |  |  | the estimate requires significant assumptions; and
| | - |  | --------------------------------------------------



| |  |  | changes in the estimate could have a material effect on our consolidated and combined results of operations or financial condition; or,
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if different estimates that could have been selected had been used, there could be a material effect on our consolidated and combined results of operations or
financial condition.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We have discussed the selection and application of these accounting estimates with the Board of
Managers and our independent auditors. It is managements view that the current assumptions and other considerations used to estimate amounts reflected in our consolidated and combined financial statements are appropriate. However, actual
results can differ significantly from those estimates under different assumptions and conditions. The sections below contain information about our most critical accounting estimates, as well as the effects of hypothetical changes in the material
assumptions used to develop the estimates.

Revenue Recognition and Accounting for Energy Trading and Marketing Activities

Nature of Estimates Required.We utilize two comprehensive accounting models in reporting our consolidated and
combined financial position and results of operations as required by GAAPan accrual model and a fair value model. We determine the appropriate model for our operations based on applicable accounting standards.



60



---

##### Table of Contents

The accrual model has historically been used to account for our revenues from the sale of energy,
capacity and ancillary services. We recognize revenue when earned and collection is probable as a result of electricity delivered to customers pursuant to contractual commitments that specify volume, price and delivery requirements. Sales of energy
are based on economic dispatch, or they may be as-ordered by an ISO, based on member participation agreements, but without an underlying contractual commitment. ISO revenues and revenues for sales of energy based on economic-dispatch are
recorded on the basis of MWh delivered, at the relevant day-ahead or real-time prices.

The fair value model has historically been used for
derivative energy contracts that economically hedge our electricity generating facilities or that are used in our proprietary trading activities. We use a variety of derivative contracts, such as futures, swaps and option contracts, in the
management of our business. Such derivative contracts have varying terms and durations, or tenors, which range from a few days to a number of years, depending on the instrument.

Pursuant to SFAS 133, derivative contracts are reflected in our financial statements at fair value, with changes in fair value recognized currently in
earnings unless they qualify for a scope exception. We deferred inception gains and losses in accordance with EITF 02-3 for the periods presented. Management considers fair value techniques, valuation adjustments related to credit and liquidity and
judgments related to the probability of completing forecasted transactions to be critical accounting estimates. These estimates are considered significant because they are highly susceptible to change from period to period and are dependent on many
subjective factors. The fair value of derivative contracts is included in price risk management assets and liabilities affiliate and nonaffiliate in our consolidated balance sheets. Transactions that do not qualify for accounting under
SFAS 133, either because they are not derivatives or because they qualify for a scope exception, are accounted for under accrual accounting as described above.

Key Assumptions and Approach Used.Determining the fair value of derivatives involves significant estimates based largely on the mid-point of quoted prices in active markets. The
mid-point may vary significantly from the bid or ask price for some delivery points. If no active market exists, we estimate the fair value of certain derivative contracts using quantitative pricing models. Fair value estimates involve uncertainties
and matters of significant judgment. Our modeling techniques for fair value estimation include assumptions for market prices, supply and demand market data, correlation and volatility. The degree of complexity of our pricing models increases for
longer duration contracts, contracts with multiple pricing features, option contracts and off-hub delivery points.

The fair value of price
risk management assets and liabilities affiliate and nonaffiliate in our consolidated balance sheets is also affected by our assumptions as to interest rate, counterparty credit risk and liquidity risk. The nominal value of the contracts is
discounted using a forward interest rate curve based on LIBOR. In addition, the fair value of our price risk management assets is reduced to reflect the estimated risk of default of counterparties on their contractual obligations to us.

Effect if Different Assumptions Used.The amounts recorded as revenue or cost of fuel, electricity and other
products change as estimates are revised to reflect actual results and changes in market conditions or other factors, many of which are beyond our control. Because we use derivative financial instruments and have not elected cash flow or fair value
hedge accounting under SFAS 133, certain components of our financial statements, including gross margin, operating income and balance sheet ratios, are at times volatile and subject to fluctuations in value primarily as a result of changes in energy
and fuel prices. As a result of the complexity of the models used to value some of the derivative instruments each period, a significant change in estimate could have a material effect on our results of operations and cash flows at the time
contracts are ultimately settled. Upon the adoption of SFAS 157 on January 1, 2008, we will no longer defer inception gains and losses. Additionally, we will incorporate our own credit standing in the fair value measurement of our liabilities.
Upon the adoption of FSP FIN 39-1 on January 1, 2008, we will net cash collateral in the measurement of the fair value of our derivative contracts under master netting arrangements. See Note 4 to our consolidated and combined

Long-Lived Assets

Estimated Useful Lives

Nature of Estimates Required.The estimated useful lives of
our long-lived assets are used to compute depreciation expense, determine the carrying value of asset retirement obligations, and estimate expected future cash flows attributable to an asset for the purposes of impairment testing. Estimated useful
lives are based, in part, on the assumption that we provide an appropriate level of capital expenditures while the assets are still in operation. Without these continued capital expenditures, the useful lives of these assets could decrease
significantly.

Key Assumptions and Approach Used.Estimated useful lives are the mechanism by which
we allocate the cost of long-lived assets over the assets service period. We perform depreciation studies periodically to update changes in estimated useful lives. The actual useful life of an asset could be affected by changes in estimated or
actual commodity prices, environmental regulations, various legal factors, competitive forces and our liquidity and ability to sustain required maintenance expenditures and satisfy asset retirement obligations. We use composite depreciation for
groups of similar assets and establish an average useful life for each group of related assets. In accordance with SFAS 144, we cease depreciation on long-lived assets classified as held for sale. Also, we may revise the remaining useful life of an
asset held and used subject to impairment testing. See Note 5 to our consolidated and combined financial statements contained elsewhere in this report for additional information related to our property, plant and equipment.

Effect if Different Assumptions Used.The determination of estimated useful lives is dependent on subjective factors
such as expected market conditions, commodity prices and anticipated capital expenditures. Since composite depreciation rates are used, the actual useful life of a particular asset may differ materially from the useful life estimated for the related
group of assets. In the event the useful lives of significant assets were found to be shorter than originally estimated, depreciation expense may increase, liabilities recognized for future asset retirement obligations may be insufficient and
impairments in the carrying value of tangible and intangible assets may result.

Asset Retirement Obligations

Nature of Estimates Required.We account for asset retirement obligations under SFAS 143 and under FIN 47. SFAS
143 and FIN 47 require an entity to recognize the fair value of a liability for conditional and unconditional asset retirement obligations in the period in which they are incurred. Retirement obligations associated with long-lived assets included
within the scope of SFAS 143 and FIN 47 are those obligations for which a requirement exists under enacted laws, statutes and written or oral contracts, including obligations arising under the doctrine of promissory estoppel. Asset retirement
obligations are estimated using the estimated current cost to satisfy the retirement obligation, increased for inflation through the expected period of retirement and discounted back to present value at our credit-adjusted risk free rate. We have
identified certain retirement obligations within our power generating operations and have a noncurrent liability of $44 million recorded as of December 31, 2007. These asset retirement obligations are primarily related to asbestos abatement at
some of our generating facilities, the removal of oil storage tanks, equipment on leased property and environmental obligations related to the closing of ash disposal sites.

##### Table of Contents

Key Assumptions and Approach Used.The fair value of liabilities
associated with the initial recognition of asset retirement obligations is estimated by applying a present value calculation to current engineering cost estimates of satisfying the obligations. Significant inputs to the present value calculation
include current cost estimates, estimated asset retirement dates and appropriate discount rates. Where appropriate, multiple cost and/or retirement scenarios have been probability weighted.

Effect if Different Assumptions Used.We update liabilities associated with asset retirement obligations as
significant assumptions change or as relevant new information becomes available. However, as a result of changes in inflation assumptions, interest rates and asset useful lives, actual future cash flows required to satisfy asset retirement
obligations could differ materially from the current recorded liabilities.

Asset Impairments

Nature of Estimates Required.We evaluate our long-lived assets, including intangible assets for impairment in
accordance with applicable accounting guidance. The amount of an impairment charge is calculated as the excess of the assets carrying value over its fair value, which generally represents the discounted expected future cash flows attributable
to the asset or in the case of assets we expect to sell, at fair value less costs to sell.

Property, Plant and Equipment and Definite-Lived
Intangibles

SFAS 144 requires management to recognize an impairment charge if the sum of the undiscounted expected future cash
flows from a long-lived asset or definite-lived intangible is less than the carrying value of that asset. We evaluate our long-lived assets (property, plant and equipment) and definite-lived intangibles for impairment whenever indicators of
impairment exist or when we commit to sell the asset. These evaluations of long-lived assets and definite-lived intangibles may result from significant decreases in the market price of an asset, a significant adverse change in the extent or manner
in which an asset is being used or in its physical condition, a significant adverse change in legal factors or in the business climate that could affect the value of an asset, as well as other economic or operations analyses. If the carrying amount
is not recoverable, an impairment charge is recorded.

Key Assumptions and Approach Used.    The fair value of
an asset is the amount at which the asset could be bought or sold in a current transaction between willing parties, that is, other than in a forced or liquidation sale. Quoted market prices in active markets are the best evidence of fair value and
are used as the basis for the measurement, when available. In the absence of quoted prices for identical or similar assets, fair value is estimated using various internal and external valuation methods. These methods include discounted cash flow
analyses and reviewing available information on comparable transactions. The determination of fair value requires management to apply judgment in estimating future energy prices, environmental and maintenance expenditures and other cash flows. Our
estimates of the fair value of the assets include significant assumptions about the timing of future cash flows, remaining useful lives and selecting a discount rate that reflects the risk inherent in future cash flows.

In 2006, our assessment of the Bowline unit 3 suspended construction project resulted in the conclusion that the Bowline 3 project as configured and
permitted was not economically viable. As a result of this conclusion, we determined the estimated value of the equipment and project termination liabilities. The carrying value of the development and construction costs for Bowline unit 3 exceeded
the estimated undiscounted cash flows from the abandonment of the project. We recorded an impairment of $120 million, which is reflected in impairment losses on the consolidated statements of operations for the year ended December 31, 2006.

As a result of entering into the amendment to the 2003 Consent Decree and the Tax Assessments Agreement, we tested the recoverability of
the Lovett facility under SFAS 144 in the second quarter of 2007. Our estimate of cash flows related to our impairment analysis of our Lovett generating facility involved considering



63

##### Table of Contents

scenarios for the future expected operation of the Lovett facility. The most likely scenario considered was the shutdown of unit 5 by April 30, 2008,
according to the amended 2003 Consent Decree. We also considered a scenario that assumes operations, utilizing coal as the primary fuel source, through 2012 to allow the Lovett facility to continue to contribute to the reliability of the electric
system of the State of New York. As a result of the analysis, we recorded an impairment of long-lived assets of $175 million in the second quarter of 2007 to reduce the carrying value of the Lovett facility to its estimated fair value. There
have been no significant changes to the assumptions used in the impairment analysis since the second quarter of 2007.

Effect if
Different Assumptions Used.    The estimates and assumptions used to determine whether an impairment exists are subject to a high degree of uncertainty. The estimated fair value of an asset would change if different estimates
and assumptions were used in our applied valuation techniques, including estimated undiscounted cash flows, discount rates and remaining useful lives for assets held and used. If actual results are not consistent with the assumptions used in
estimating future cash flows and asset fair values, we may be exposed to additional losses that could be material to our results of operations. See Note 5 to our consolidated and combined financial statements contained elsewhere in this report for
additional information on impairments.

Income Taxes

We are a limited liability company treated as a branch for income tax purposes. As a result, Mirant Americas and Mirant have direct liability for the majority of the federal and state income taxes relating to our
operations. Through December 31, 2005, we allocated current and deferred income taxes to each regarded corporate member entity of our consolidated group as if each regarded corporate entity member was a single taxpayer utilizing the asset and
liability method to account for income taxes except with respect to recognizing certain current period tax benefits. Specifically, we did not record current period tax benefits on each regarded corporate entitys ability to carry back its
separate company current year NOL as realization of such losses is dependent on reimbursements from Mirant, which were at Mirants discretion under the tax sharing agreement. Deferred tax assets and liabilities are recognized for future tax
consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and NOL and tax credit carryforwards. When necessary, deferred tax assets are reduced by a
valuation allowance to reflect the amount that is estimated to be recoverable. In assessing the recoverability of our deferred tax assets, we consider whether it is likely that some portion or all of the deferred tax assets will be realized.
Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities
of a change in tax rates is recognized in income in the period that includes the enacted change.

Several significant changes to our tax
posture occurred as a result of the Plan. Implementation of the Plan included the conversion of certain of our regarded corporate entities to limited liability companies coupled with the liquidation and/or merger of these regarded corporate entities
into other disregarded corporate entities for income tax purposes. As a result, certain subsidiaries previously treated as regarded corporate entities for income tax purposes have either been liquidated or converted into disregarded entities for
income tax purposes pursuant to the Plan. Additionally, certain partnerships owned by the regarded corporate entities were also liquidated, and now form part of these disregarded entities for income tax purposes. The result of the above Plan effects
was to eliminate our recording of tax expense and benefit prospectively with respect to the liquidated regarded corporate entities. Furthermore, with respect to those liquidated regarded corporate entities, all previously existing deferred tax
assets and liabilities were eliminated as of December 31, 2005. Certain of our other subsidiaries continue to exist as regarded corporate entities for income tax purposes, including Hudson Valley Gas, Mirant Kendall and Mirant Special
Procurement, Inc. In May 2007, Mirant New York was converted to a limited liability company, resulting in the elimination of any existing deferred tax assets and liabilities related to Mirant New York.

When it emerged from bankruptcy, Mirant terminated the tax sharing agreement with its direct and indirect wholly-owned regarded corporate entities. As a
result, Mirants direct and indirect wholly-owned regarded corporate entities are no longer responsible for reimbursing Mirant for their intercompany tax obligations

attributable to their operations. Accordingly, our income tax receivables and payables with Mirant or Mirant Americas were resolved pursuant to a global
settlement under the Plan whereby intercompany receivables and payables received no distribution. The income tax payables and receivables related to Mirant New York, which remained in bankruptcy at December 31, 2006, were resolved upon its
emergence from Bankruptcy, which became effective on April 16, 2007; however, for financial statement purposes, we recorded the effects of its plan of reorganization on March 31, 2007.

For those subsidiaries that continue to exist as corporate regarded entities, we allocate current and deferred income taxes to each corporate regarded
entity as if such entity were a single taxpayer utilizing the asset and liability method to account for income taxes. To the extent we provide tax expense or benefit, any related tax payable or receivable to Mirant is reclassified to equity in the
same period.

The determination of a valuation allowance requires significant judgment as to the generation of taxable income during future
periods for which temporary differences are expected to be deductible. In making this determination, management considers all available positive and negative evidence affecting specific deferred tax assets, including our past and anticipated future
performance, the reversal of deferred tax liabilities and the implementation of tax planning strategies.

Additionally, we have not
recognized any tax benefits relating to tax uncertainties arising in the ordinary course of business that are less than or subject to the measurement threshold of the more-likely-than-not standard prescribed under FIN 48. An unrecognized tax benefit
may be either a tax liability or an adjustment to our NOLs based on the specific facts of each tax uncertainty. We periodically assess our tax uncertainties based on the latest information available. The amount of any unrecognized tax benefit
requires management to make significant assumptions about the expected outcomes of certain tax positions included in Mirants filed or yet to be filed tax returns. See Note 2 to our consolidated and combined financial statements contained
elsewhere in this report for information about our January 1, 2007, adoption of FIN 48.

Loss Contingencies

Nature of Estimates Required.We record loss contingencies when it is probable that a liability has been incurred
and the amount can be reasonably estimated. We consider loss contingency estimates to be critical accounting estimates because they entail significant judgment regarding probabilities and ranges of exposure, and the ultimate outcome of the
proceedings is unknown and could have a material adverse effect on our results of operations, financial condition and cash flows. We currently have loss contingencies related to litigation, environmental matters, tax matters and others.

Key Assumptions and Approach Used.The determination of a loss contingency requires significant judgment as to
the expected outcome of each contingency in future periods. In making the determination as to potential losses and probability of loss, we consider all available positive and negative evidence including the expected outcome of potential litigation.
We record our best estimate of a loss, or the low end of our range if no estimate is better than another estimate within a range of estimates, when the loss is considered probable. As additional information becomes available, we reassess the
potential liability related to the contingency and revise our estimates. In our evaluation of legal matters, management holds discussions with applicable legal counsel and relies on analysis of case law and legal precedents.

Effect if Different Assumptions Used.Revisions in our estimates of potential liabilities could materially affect
our results of operations and the ultimate resolution may be materially different from the estimates that we make.

|Item 7A. | Quantitative and Qualitative Disclosures about Market Risk
|-------- | ----------------------------------------------------------

We are exposed to market risks associated with commodity prices, interest rates and credit risk.

Commodity Price Risk

In connection with our business of generating electricity, we are exposed to energy commodity price risk associated with the
acquisition of fuel needed to generate electricity, as well as the price of electricity produced and sold. A portion of our fuel requirements is purchased in the spot market and a portion of the electricity we produce is sold in the spot market. In
addition, the open positions in our proprietary trading activities expose us to risks associated with changes in energy commodity prices. As a result, our financial performance varies depending on changes in the prices of energy and energy-related
commodities. See Critical Accounting Estimates for a discussion of the accounting treatment for proprietary trading and asset management activities.

The financial performance of our business of generating electricity is influenced by the difference between the variable cost of converting a fuel, such as natural gas, oil or coal, into electricity, and the revenue
we receive from the sale of that electricity. The difference between the cost of a specific fuel used to generate one MWh of electricity and the market value of the electricity generated is commonly referred to as the conversion spread.
Absent the effects of our price risk management activities, the operating margins that we realize are equal to the difference between the aggregate conversion spread and the cost of operating the facilities that produce the electricity sold.

Conversion spreads are dependent on a variety of factors that influence the cost of fuel and the sales price of the electricity generated
over the longer term, including conversion spreads of other generating facilities in the regions in which we operate, facility outages, weather and general economic conditions. As a result of these influences, the cost of fuel and electricity prices
do not always change in the same magnitude or direction, which results in conversion spreads for a particular generating facility widening or narrowing (or becoming negative) over any given period.

Through our asset management activities, we enter into a variety of exchange-traded and OTC energy and energy-related derivative contracts, such as
forward contracts, futures contracts, option contracts and financial swap agreements to manage our exposure to commodity price risks and changes in conversion spreads. These contracts have varying terms and durations which range from a few days to
years, depending on the instrument. Our proprietary trading activities also utilize similar contracts in markets where we have a physical presence to attempt to generate incremental gross margin.

Derivative energy contracts that are required to be reflected at fair value are presented as price risk management assets and liabilitiesaffiliate
and nonaffiliate in the accompanying consolidated balance sheets. The net changes in their market values are recognized in income in the period of change. The determination of fair value considers various factors, including closing exchange or OTC
market price quotations, time value, credit quality, liquidity and volatility factors underlying options.

The volumetric weighted average
maturity, or weighted average tenor, of the price risk management portfolio at December 31, 2007, was approximately 12 months. The net notional amount, or net short position, of the price risk management assets and liabilitiesaffiliate
and nonaffiliate at December 31, 2007, was approximately 26 million equivalent MWh.

Value at Risk

Our Risk Management Policy prohibits the trading of certain products (e.g., natural gas liquids and pulp and paper) and contains limits and restrictions related to our asset management and proprietary trading
activities.

We manage the price risk associated with asset management activities through a variety of methods. Our Risk Management Policy
requires that asset management activities are restricted to only those activities that are risk-reducing. We ensure compliance with this restriction at the transactional level by testing each individual transaction executed relative to the overall
asset position.

We also use VaR to measure the market price risk of our energy asset portfolio as a result of potential
changes in market prices. VaR is a statistical model that provides an estimate of potential loss. We calculate VaR based on the parametric variance/covariance approach, utilizing a 95% confidence interval and a one-day holding period on a rolling
24-month forward looking period. Additionally, we estimate correlation based on historical commodity price changes. Volatilities are based on a combination of historical price changes and implied market rates.

VaR is calculated on an asset management portfolio comprised of mark-to-market and non mark-to-market energy assets and liabilities including generating
facilities and bilateral physical and financial transactions. We also calculate VaR on portfolios consisting of mark-to-market and non mark-to-market bilateral physical and financial transactions related to our proprietary trading activities and
fuel oil management operations. Asset management VaR levels are substantially reduced due to our decision to hedge actively in the forward markets the commodity price risk related to the expected generation and fuel usage of our generating
facilities. See Item 1. Commercial Operations for discussion of our hedging strategies and Item 7. Critical Accounting Estimates for the accounting treatment of asset management and proprietary trading activities.

The asset management VaR declined for the year ended December 31, 2007, as compared to the
year ended December 31, 2006, primarily as a result of increased hedging activity against our underlying generating facilities.

Because of inherent limitations of statistical measures such as VaR and the seasonality of changes in market prices, the VaR calculation may not reflect the full extent of our commodity price risk exposure. Additionally, actual changes in
the fair value of mark-to-market energy assets and liabilities could differ from the calculated VaR, and such changes could have a material effect on our financial results.

Interest Rate Risk

We have two loans that provide for a variable rate of interest. Interest expense
on such borrowings is sensitive to changes in the market rate of interest.

Our total debt from operations that is subject to variable
interest rates through either our senior secured term loan or our senior secured revolving credit facility, assuming they are fully drawn, is approximately $1.4 billion. A 1% per annum increase in the average market rate would result in an
increase in our annual interest expense of approximately $14 million.

Credit Risk

Credit risk represents the loss that we would incur if a counterparty failed to perform under its contractual obligations less the value of collateral held by us. We have established controls and procedures in our Risk Management Policy to
determine and monitor the creditworthiness of customers and counterparties. Our credit policies are established and monitored by the Risk Oversight Committee. The Risk Oversight Committee includes the Chief Financial Officer and managements
representatives from several functional areas. We use published ratings of customers, as well as our internal analysis, to guide us in the process of setting credit levels, risk limits and contractual arrangements, including master netting
agreements. Where external ratings are not available, we rely on our internal assessments of customers.

Collection Risk

Once we bill a customer for the commodity delivered or have financially settled the credit risk, we are subject to collection risk. Collection risk is
similar to credit risk and collection risk is accounted for when we establish our allowance for bad debts. We manage this risk using the same techniques and processes used in credit risk discussed above.

Report of Independent Registered Public Accounting Firm

The Member

Mirant Americas Generation, LLC:

We have audited the
accompanying consolidated balance sheets of Mirant Americas Generation, LLC (a wholly-owned indirect subsidiary of Mirant Corporation) and subsidiaries (the Company) as of December 31, 2007 and 2006, and the related consolidated
statements of operations, equity and comprehensive income (loss) and cash flows for each of the years in the two-year period ended December 31, 2007, and the related combined statements of operations, equity and comprehensive income (loss) and
cash flows for the year ended December 31, 2005. These consolidated and combined financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these consolidated and combined
financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated and combined
financial statements referred to above present fairly, in all material respects, the financial position of Mirant Americas Generation, LLC and subsidiaries as of December 31, 2007 and 2006, and the results of their operations and their cash
flows for each of the years in the three-year period ended December 31, 2007, in conformity with U.S. generally accepted accounting principles.

As discussed in Note 2 to the consolidated and combined financial statements, the Company adopted Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes,in
2007 and Financial Accounting Standards Board Interpretation No. 47,Accounting for Conditional Asset Retirement Obligations: an interpretation of FASB Statement No. 143, in 2005.

MIRANT AMERICAS GENERATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS

December 31,
2007, 2006 and 2005

1.    Description of Business and Organization

Mirant Americas Generation is a competitive energy company that produces and sells electricity. The Company owns or leases 10,280 MW of electric
generating capacity located in markets in the Mid-Atlantic and Northeast regions and in California. The Company also operates an integrated asset management and energy marketing organization based in Atlanta, Georgia.

Mirant Americas Generation is a Delaware limited liability company and an indirect wholly-owned subsidiary of Mirant. Mirant Corporation was incorporated
in Delaware on September 23, 2005. Pursuant to the Plan for Mirant and certain of its subsidiaries, on January 3, 2006, New Mirant emerged from bankruptcy and acquired substantially all of the assets of Old Mirant, a corporation that was
formed in Delaware on April 3, 1993, and that had been named Mirant Corporation prior to January 3, 2006.

In the third quarter
of 2006, Mirant commenced auction processes to sell six U.S. natural gas-fired facilities including the Companys indirectly owned Zeeland and Bosque facilities. On May 1, 2007, the Company completed the sale of the Zeeland and Bosque
natural gas-fired facilities. In addition, on May 7, 2007, the Company completed the sale of Mirant NY-Gen, an indirect wholly-owned subsidiary. In accordance with Mirant North Americas debt covenants, approximately $524 million of
the proceeds from the sale of the Zeeland and Bosque facilities are being reinvested in the business of Mirant North America. At December 31, 2007, $273 million of such proceeds have been reinvested in Mirant North America. See Note 10 for
additional information regarding the accounting for these facilities as discontinued operations.

On April 9, 2007, Mirant announced
that its Board of Directors had decided to explore strategic alternatives to enhance stockholder value. In the exploration process, the Board of Directors considered whether the interests of stockholders would be best served by returning excess cash
from the sale proceeds to stockholders, with Mirant continuing to operate its retained businesses or, alternatively, whether greater stockholder value would be achieved by entering into a transaction with another company, including a sale of Mirant
in its entirety. On November 9, 2007, Mirant announced the conclusion of the strategic review process. Mirant plans to return a total of $4.6 billion of excess cash to its stockholders.

The accompanying consolidated financial statements include the accounts of Mirant Americas Generation and reflect the effects of the Plan as of
December 31, 2005, including:



| |  |  | The contribution by Mirant of its interest in Mirant Potomac River and Mirant Peaker to the Companys indirect wholly-owned subsidiary, Mirant Mid-Atlantic,
and its interest in Mirant Zeeland and in Mirant Americas Energy Marketing, Mirant Americas Development, Inc., Mirant Americas Production Company, Mirant Americas Energy Capital, LLC, Mirant Americas Energy Capital Assets, LLC, Mirant Americas
Development Capital, LLC, Mirant Americas Retail Energy Marketing, LP, and Mirant Americas Gas Marketing I-XV, LLCs (collectively, the Trading Debtors) to Mirant North America. All of the contributed subsidiaries were under the common
control of Mirant and are collectively referred to as the Contributed Subsidiaries.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The transfer of the trading and marketing business of the Trading Debtors to Mirant Energy Trading, a wholly-owned subsidiary of Mirant North America. After these
transfers took place on January 31, 2006, the Trading Debtors were transferred to a trust created under the Plan that is not affiliated with the Company.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The accompanying 2005 combined financial statements present the results of operations and cash flows based on the assets, liabilities and operations of
the predecessor Contributed Subsidiaries.

2.    Accounting and Reporting Policies

Basis of Presentation

The accompanying
consolidated and combined financial statements of Mirant Americas Generation have been prepared in accordance with GAAP.

The accompanying
consolidated and combined financial statements include the accounts of Mirant Americas Generation and its wholly-owned subsidiaries and the Contributed Subsidiaries as discussed in Note 1 and have been prepared from the records maintained by Mirant
Americas Generation, its subsidiaries and the Contributed Subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

In preparing the Companys 2007 consolidated statement of cash flow, the Company discovered that capitalized interest expense for projects under construction had been included in cash flows from operating
activities, rather than cash flows from investing activities in 2006. The result of the misstatement was an understatement of cash provided by operating activities and an understatement of cash used in investing activities of approximately $6
million for the year ended December 31, 2006. The misstatement had no effect on cash, net income, or stockholders equity. The consolidated statement of cash flows for the year ended December 31, 2006, has been adjusted to reflect the
immaterial correction of this misstatement.

In accordance with SFAS 144, the results of operations of the Companys facilities that
have been disposed of and have met the criteria for such classification, have been reclassified to discontinued operations and the associated assets and liabilities have been reclassified to assets and liabilities held for sale for all periods
presented.

Certain prior period amounts have been reclassified to conform to the current year financial statement presentation.

Use of Estimates

The
preparation of consolidated and combined financial statements in conformity with GAAP requires management to make a number of estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets
and liabilities at the date of the consolidated and combined financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates. The Companys significant estimates
include:



| |  |  | determining the fair value of certain derivative contracts;
| | - |  | -----------------------------------------------------------



| |  |  | estimating future taxable income in determining its deferred tax asset valuation allowance;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | estimating the useful lives of the Companys long-lived assets;
| | - |  | ---------------------------------------------------------------



| |  |  | determining the value of the Companys asset retirement obligations;
| | - |  | --------------------------------------------------------------------



| |  |  | estimating future cash flows in determining impairments of long-lived assets and definite-lived intangible assets; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | estimating losses to be recorded for contingent liabilities.
| | - |  | ------------------------------------------------------------

Revenue Recognition

Mirant Americas Generation recognizes revenue from the sale of energy when earned and
collection is probable. Some sales of energy are based on economic dispatch or as-ordered by an ISO, based on member participation agreements, but without an underlying contractual commitment. ISO revenues and revenues from sales of
energy based on economic-dispatch are recorded on the basis of MWh delivered, at the relevant

day-ahead or real-time prices. When a long-term electric power agreement conveys to the buyer of the electric power the right to use the generating capacity
of Mirant Americas Generations facility, that agreement is evaluated to determine if it is a lease of the generating facility rather than a sale of electric power. Operating lease revenue for the Companys generating facilities is
normally recorded as capacity revenue and included in operating revenues in the consolidated and combined statements of operations.

Derivative
Financial Instruments

Derivative financial instruments are recorded in the accompanying consolidated balance sheets at fair value
as either price risk management assets or liabilities-affiliate or nonaffiliate, and changes in fair value are recognized currently in earnings, unless the Company elects to apply fair value or cash flow hedge accounting based on meeting specific
criteria in SFAS 133. For the years ended December 31, 2007, 2006 and 2005, the Company did not have any derivative instruments that it had designated as fair value or cash flow hedges for accounting purposes. Mirant Americas Generations
derivative financial instruments are categorized by the Company based on the business objective the instrument is expected to achieve: asset management or proprietary trading. All derivative contracts are recorded at fair value, except for a limited
number of transactions that qualify for the normal purchase or normal sale exclusion from SFAS 133 and therefore qualify for the use of accrual accounting.

As the Companys commodity derivative financial instruments have not been designated as hedges for accounting purposes, changes in such instruments fair values are recognized currently in earnings. For
asset management activities, changes in fair value of electricity derivative financial instruments are reflected in operating revenue-affiliate and nonaffiliate and changes in fair value of fuel derivative contracts are reflected in cost of fuel,
electricity and other products-affiliate and nonaffiliate in the accompanying consolidated and combined statements of operations. Changes in the fair value and settlements of contracts for proprietary trading activities are recorded on a net basis
as operating revenue-affiliate and nonaffiliate in the accompanying consolidated and combined statements of operations.

Concentration of Revenues

In 2007, 2006 and 2005, the Company earned a significant portion of its operating revenue and gross margin from the PJM energy
market, where its Mirant Mid-Atlantic generating facilities are located. Mirant Mid-Atlantics revenues and gross margin as a percentage of the Companys total revenues and gross margin from continuing operations are as follows:



|                   |  |                          |   |  |      |   |  |      |  
|------------------ |  | ------------------------ | - |  | ---- | - |  | ---- | -
|                   |  | Years Ended December 31, |  
|                   |  | 2007                     |   |  | 2006 |   |  | 2005 |  
|Operating revenues |  | 56                       | % |  | 58   | % |  | 41   | %
|Gross margin       |  | 60                       | % |  | 68   | % |  | 55   | %

Concentration of Labor Subject to Collective Bargaining Agreements

Under Mirant Americas Generations services agreement with Mirant Services, a direct subsidiary of Mirant, Mirant Services provides the
Companys personnel. At December 31, 2007, approximately 1,255 Mirant Services employees worked at the Companys facilities. At December 31, 2007, approximately 66% of the Companys total employees are subject to collective
bargaining agreements, of which 60% are subject to the collective bargaining agreement in the Mid-Atlantic region.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less to be cash equivalents. At
December 31, 2007, except for amounts held in bank accounts to cover current payables, all of the Companys cash and cash equivalents were invested in AAA-rated U.S. Treasury money market funds.

##### Table of Contents

Restricted Cash

Restricted cash is included in current and noncurrent assets as funds on deposit and other noncurrent assets in the accompanying consolidated balance sheets. At December 31, 2007, current and noncurrent funds on
deposit were $302 million and $7 million, respectively. At December 31, 2006, current and noncurrent funds on deposit were $233 million and $6 million, respectively. Restricted cash includes deposits with brokers and cash collateral posted with
third parties to support the Companys commodity positions as well as a $200 million deposit by Mirant North America posted under its senior secured term loan to support the issuance of letters of credit.

Inventory

Inventory consists primarily of
oil, coal, purchased emissions allowances and materials and supplies. Inventory, including commodity trading inventory, is generally stated at the lower of cost or market value. Fuel stock is removed from the inventory account as it is used in the
production of electricity. Materials and supplies are removed from the inventory account when they are used for repairs, maintenance or capital projects.

Purchased emissions allowances are recorded in inventory at the lower of cost or market. Cost is computed on an average cost basis. Purchased emissions allowances for SO2 and NOx are removed from inventory and charged
to cost of fuel, electricity and other products in the accompanying consolidated and combined statements of operations as they are utilized against emissions volumes that exceed the allowances granted to the Company by the EPA.

Inventory at December 31, 2007 and 2006, consisted of (in millions):

|                       |  |                 |     |      |   |    

Granted Emissions Allowances

Included in property, plant and equipment are emissions allowances granted by the EPA that were projected to be required to offset physical emissions
related to generating facilities owned by the Company. These emissions allowances were recorded at fair value at the date of the acquisition of the facility and are depreciated on a straight-line basis over the estimated useful life of the
respective generating facility and are charged to depreciation and amortization expense in the accompanying consolidated and combined statements of operations.

Included in other intangible assets are: (1) emissions allowances granted by the EPA related to generating facilities owned by the Company that are projected to be in excess of those required to offset physical
emissions; and (2) emissions allowances related to generating facilities leased by the Company. Emissions allowances related to leased generating facilities are recorded at fair value at the commencement of the lease. These emissions allowances
are amortized on a straight-line basis over a period up to 30 years for emissions allowances related to owned generating facilities or the term of the lease for emissions allowances related to leased generating facilities, and are charged to
depreciation and amortization expense in the accompanying consolidated and combined statements of operations.

As a result of the capital
expenditures Mirant North America is making to comply with the requirements of the Maryland Healthy Air Act, the Company anticipates that it will have significant excess emissions allowances in future periods. The Company plans to continue to
maintain some emissions allowances in excess of expected

generation in case its actual generation exceeds its current forecasts for future periods and for possible future additions of generating capacity. During
the fourth quarter of 2007, the Company began a program to sell excess emissions allowances dependent upon market conditions. The Company sold approximately $24 million of excess emissions allowances and recognized a gain of $22 million, which is
included in gain on sales of assets in the consolidated statement of operations for the year ended December 31, 2007. The Company has determined that certain exchanges of emissions allowances that the Company may periodically transact qualify
as nonmonetary exchanges under SFAS 153.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost, which includes materials, labor, and associated payroll-related and overhead costs and the cost of
financing construction. The cost of routine maintenance and repairs, such as inspections and corrosion removal, and the replacement of minor items of property are charged to expense as incurred. Certain expenditures incurred during a major
maintenance outage of a generating facility are capitalized, including the replacement of major component parts and labor and overhead incurred to install the parts. Depreciation of the recorded cost of depreciable property, plant and equipment is
determined using primarily composite rates. Leasehold improvements are depreciated over the shorter of the expected life of the related equipment or the lease term. Upon the retirement or sale of property, plant and equipment the cost of such assets
and the related accumulated depreciation are removed from the consolidated balance sheets. No gain or loss is recognized for ordinary retirements in the normal course of business since the composite depreciation rates used by the Company take into
account the effect of interim retirements.

Capitalization of Interest Cost

The Company capitalizes interest on projects during their construction period. The Company determines which debt instruments represent a reasonable
measure of the cost of financing construction assets in terms of interest cost incurred that otherwise could have been avoided. These debt instruments and associated interest costs are included in the calculation of the weighted average interest
rate used for determining the capitalization rate. Once placed in service, capitalized interest, as a component of the total cost of the plant, is amortized over the estimated useful life of the plant. For the years ended December 31, 2007,
2006 and 2005, the Company incurred the following interest costs on debt to nonaffiliates (in millions):



|                                                               |  |                          |     |   |      |   |     |      |  |   |

|Interest expensenonaffiliate                                  |  | $                        | 245 |   |      | $ | 289 |      |  | $ | 759

In the third quarter of 2005, the Company determined that it was probable that contractual
interest on liabilities subject to compromise from the Petition Date would be incurred for certain claims expected to be allowed under the Plan and, accordingly, recorded approximately $746 million of interest expense in 2005 on liabilities subject
to compromise.

Operating Leases

Mirant Americas Generation leases various assets under non-cancelable leasing arrangements, including generating facilities, office space and other equipment. The rent expense associated with leases that qualify as operating
leases is recognized on a straight-line basis over the lease term within operations and maintenance expensenonaffiliate in the consolidated and combined statement of operations. The Companys most significant operating leases
are Mirant Mid-Atlantics leases of the Morgantown and Dickerson baseload units, which expire in 2034 and 2029, respectively. The Company has an option to extend these leases. Any extensions

##### Table of Contents

of the respective leases would be limited to 75% of the economic useful life of the facility, as measured from the beginning of the original lease term
through the end of the proposed remaining lease term. As of December 31, 2007, the total notional minimum lease payments for the remaining terms of the leases of the Morgantown and Dickerson baseload units aggregated approximately
$2.1 billion.

Intangible Assets

Intangible assets with definite useful lives are amortized on a straight-line basis over their respective useful lives ranging up to 40 years to their estimated residual values.

Investments

For the years ended December 31, 2006 and 2005, the Company completed the
sales of investments described below. The related gains are recorded in gain on sales of investments, net in the consolidated and combined statements of operations.

Equity Investment in InterContinental Exchange.In 2005, the Company sold a portion of its investment in InterContinental Exchange for $48 million and realized a gain of $44
million. In 2006, the Company sold its remaining investment in InterContinental Exchange for $58 million and realized a gain of $54 million.

New York Mercantile Exchange Seats.In late 1998 and early 1999, the Company acquired two seats on the New York Mercantile Exchange. In 2006, the Company sold its investment for $20 million and
recognized a gain of $19 million, which is recorded in gain on sales of investments, net on the Companys consolidated statement of operations.

Environmental Remediation Costs

The Company accrues for costs associated with environmental remediation when such
costs are probable and can be reasonably estimated. Accruals for estimated losses from environmental remediation obligations generally are recognized no later than completion of the remediation feasibility study. Such accruals are adjusted as
further information develops or circumstances change. The cost of future expenditures for environmental remediation obligations are discounted to their present value.

Debt Issuance Costs

Debt issuance costs are capitalized and amortized as interest expense on
a basis that approximates the effective interest method over the term of the related debt.

Income Taxes

The Company is a limited liability company treated as a branch for income tax purposes. As a result, Mirant Americas and Mirant have direct liability for
the majority of the federal and state income taxes relating to the Companys operations. Through December 31, 2005, the Company has allocated current and deferred income taxes to each regarded corporate entity of its consolidated group as
if each regarded corporate entity were a single taxpayer utilizing the asset and liability method to account for income taxes except with respect to recognizing certain current period tax benefits. Specifically, the Company did not record current
period tax benefits on each regarded corporate entitys ability to carry back its separate company current year NOL as realization of such losses is dependent on reimbursements from Mirant, which were at Mirants discretion under the tax
sharing agreement. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and
operating loss and tax credit carryforwards. When necessary, deferred tax assets are reduced by a valuation allowance to reflect the amount that is estimated to be recoverable. In assessing the recoverability of its



F-11



---

##### Table of Contents

deferred tax assets, the Company considers whether it is likely that some portion or all of the deferred tax assets will be realized. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.

Several significant changes to the Companys tax
posture occurred as a result of the Plan. Implementation of the Plan included the conversion of certain of the Companys regarded corporate entities to limited liability companies coupled with the liquidation and/or merger of these regarded
corporate entities into other disregarded corporate entities for income tax purposes. As a result, certain subsidiaries previously treated as regarded corporate entities for income tax purposes have either been liquidated or converted into
disregarded entities for income tax purposes pursuant to the Plan. Additionally, certain partnerships owned by the regarded corporate entities were also liquidated, and now form part of these disregarded entities for income tax purposes. The result
of the above Plan effects was to eliminate the Companys recording of tax expense and benefit prospectively with respect to the liquidated regarded corporate entities. Furthermore, with respect to those liquidated regarded corporate entities,
all previously existing deferred tax assets and liabilities were eliminated as of December 31, 2005. Certain of the Companys other subsidiaries continue to exist as regarded corporate entities for income tax purposes, including Hudson
Valley Gas, Mirant Kendall and Mirant Special Procurement, Inc. In May 2007, Mirant New York was converted to a limited liability company, resulting in the elimination of any existing deferred tax assets and liabilities related to Mirant
New York.

When it emerged from bankruptcy, Mirant terminated the tax sharing agreement with its direct and indirect wholly owned regarded
corporate entities. As a result, Mirants direct and indirect wholly owned regarded corporate entities are no longer responsible for reimbursing Mirant for their intercompany tax obligations attributable to their operations. Accordingly, the
Companys income tax receivables and payables with Mirant or Mirant Americas were resolved pursuant to a global settlement under the Plan whereby intercompany receivables and payables received no distribution. The income tax payables and
receivables related to Mirant New York, which remained in bankruptcy at December 31, 2006, were resolved upon its emergence from Bankruptcy, which became effective on April 16, 2007; however, for financial statement purposes, Mirant
Americas Generation recorded the effects of the plan of reorganization on March 31, 2007.

For those subsidiaries that continue to
exist as corporate regarded entities, the Company continues to allocate current and deferred income taxes to each corporate regarded entity as if such entity were a single taxpayer utilizing the asset and liability method to account for income
taxes. To the extent the Company provides tax expense or benefit, any related tax payable or receivable to Mirant is reclassified to equity in the same period.

SFAS 109 requires that a valuation allowance be established when it is more-likely-than-not that all or a portion of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets is
dependent upon the generation of future taxable income during the periods in which those temporary differences are deductible. In making this determination, management considers all available positive and negative evidence affecting specific
deferred tax assets, including the Companys past and anticipated future performance, the reversal of deferred tax liabilities and the implementation of tax planning strategies.

Objective positive evidence is necessary to support a conclusion that a valuation allowance is not needed for all or a portion of deferred tax assets
when significant negative evidence exists.

Impairment of Long-Lived Assets

The Company evaluates long-lived assets, such as property, plant and equipment, and purchased intangible assets subject to amortization, for impairment
whenever events or changes in circumstances indicate that the

carrying amount of the asset may not be recoverable. Such evaluations are performed in accordance with SFAS 144. Recoverability of assets to be held and used
is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, an
impairment charge is recognized as the amount by which the carrying amount of the asset exceeds its fair value. Assets to be disposed of are separately presented in the accompanying consolidated balance sheets and are reported at the lower of the
carrying amount or fair value less costs to sell, and are not depreciated. The assets and liabilities of a disposal group classified as held for sale are presented separately in the appropriate asset and liability sections of the accompanying
consolidated balance sheets.

Cumulative Effect of Changes in Accounting Principles

The Company adopted FIN 47, effective December 31, 2005, related to the costs associated with conditional legal obligations to retire tangible,
long-lived assets. Conditional asset retirement obligations are recorded at the fair value in the period in which they are incurred by increasing the carrying amount of the related long-lived asset. In each subsequent period, the liability is
accreted to its fair value and the capitalized costs are depreciated over the useful life of the related asset. For the year ended December 31, 2005, the Company recorded a charge as a cumulative effect of changes in accounting principle of
approximately $15 million, net of tax, related to the adoption of this accounting standard.

Fair Value of Financial Instruments

SFAS No. 107 requires the disclosure of the fair value of all financial instruments that are not otherwise recorded at fair value in the financial
statements. At December 31, 2007 and 2006, financial instruments recorded at contractual amounts that approximate market or fair value include cash and cash equivalents, funds on deposit, receivables from affiliate and customer accounts receivable,
accounts payable and accrued liabilities, payable to affiliate and notes payable-affiliate. The market values of such items are not materially sensitive to shifts in market interest rates because of the short term to maturity of these instruments.
At December 31, 2007 and 2006, the fair value of the Companys long-term accounts receivable of $1 million is not readily determinable due to uncertainty regarding the amount and timing of collection from the Companys customers.

The fair value of the Companys long-term debt is estimated using quoted market prices when available. At December 31, 2007 and 2006,
the carrying value of the Companys long-term debt approximated fair value.

Recently Adopted Accounting Standards

In February 2006, the FASB issued SFAS 155, which allows fair value measurement for any hybrid financial instrument that contains an embedded
derivative that otherwise would require bifurcation. SFAS 155 is effective for all financial instruments acquired, issued or subject to a re-measurement event beginning in the first fiscal year after September 15, 2006. At the date of adoption,
any difference between the total carrying amount of the existing bifurcated hybrid financial instrument and the fair value of the combined hybrid financial instrument will be recognized as a cumulative effect adjustment to beginning retained
earnings. The Company adopted SFAS 155 on January 1, 2007. The adoption of SFAS 155 did not affect the Companys statements of operations, financial position or cash flows.

In March 2006, the FASB issued SFAS 156, which requires all separately recognized servicing assets and servicing liabilities to be measured
initially at fair value and permits, but does not require, an entity to measure subsequently those servicing assets or liabilities at fair value. The Company adopted SFAS 156 on January 1, 2007. All requirements for recognition and initial
measurement of servicing assets and servicing liabilities have been applied prospectively to transactions occurring after the adoption of this statement. The adoption of SFAS 156 did not have a material effect on the Companys statements of
operations, financial position or cash flows.

On June 28, 2006, the FASB ratified the EITFs consensus reached on EITF 06-3, which
relates to the income statement presentation of taxes collected from customers and remitted to government authorities. The Task Force affirmed as a consensus on this issue that the presentation of taxes on either a gross basis or a net basis within
the scope of EITF 06-3 is an accounting policy decision that should be disclosed pursuant to APB 22. A company should disclose the amount of those taxes that is recognized on a gross basis in interim and annual financial statements for each
period for which an income statement is presented if those amounts are significant. The Company adopted EITF 06-3 on January 1, 2007. While the amounts are not material, the Companys policy is to present such taxes on a net basis in
the consolidated statements of operations.

On July 13, 2006, the FASB issued FIN 48. FIN 48 clarifies the accounting for
uncertainty in income taxes recognized in an enterprises financial statements in accordance with SFAS 109. FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a
tax position taken or expected to be taken in a tax return. On January 1, 2007, the Company adopted the provisions of FIN 48. Only tax positions that meet the more-likely-than-not recognition threshold at the effective date were recognized or
continue to be recognized. The total effect of adopting FIN 48 was an increase in members interests of $51 million. See Note 7 for additional information on FIN 48.

On May 2, 2007, the FASB issued FSP FIN 48-1, which amended FIN 48 to provide guidance on how an enterprise should determine whether a tax position is effectively settled for the purpose of recognizing previously
unrecognized tax benefits. In determining whether a tax position is effectively settled, companies are required to make the assessment on a position-by-position basis; however, a company could conclude that all positions in a particular tax year are
effectively settled. The Companys initial adoption of FIN 48 on January 1, 2007, was consistent with the provisions of FSP FIN 48-1.

New
Accounting Standards Not Yet Adopted

On September 15, 2006, the FASB issued SFAS 157, which establishes a framework for
measuring fair value under GAAP and expands disclosure about fair value measurements. SFAS 157 requires companies to disclose the fair value of their financial instruments according to a fair value hierarchy (i.e., levels 1, 2 and 3 as defined).
Additionally, companies are required to provide enhanced disclosure regarding fair value measurements in the level 3 category, including a reconciliation of the beginning and ending balances separately for each major category of assets and
liabilities accounted for at fair value. The Company adopted the provisions of SFAS 157 on January 1, 2008, for financial instruments and nonfinancial assets and liabilities recognized or disclosed at fair value in the financial statements on a
recurring basis. The FASB deferred the effective date to January 1, 2009, for nonfinancial assets and liabilities that are not required or permitted to be measured at fair value on a recurring basis.

SFAS 157 nullifies a portion of the guidance in EITF 02-3. Under EITF 02-3, the transaction price presumption prohibited recognition of a day one gain or
loss at the inception of a derivative contract unless the fair value of that derivative was substantially based on quoted prices or a valuation process incorporating observable inputs. Day one gains or losses on transactions that had been deferred
under EITF 02-3 were recognized in the period that valuation inputs became observable or when the contract performed.

In addition, SFAS 157
also clarifies that an issuers credit standing should be considered when measuring liabilities at fair value, precludes the use of a block discount when measuring instruments traded in an actively quoted market at fair value and requires costs
relating to acquiring instruments carried at fair value to be recognized as expense when incurred. SFAS 157 requires that a fair value measurement reflect the assumptions market participants would use in pricing an asset or liability based on the
best available information.

SFAS 157 clarified that fair value should be measured at the exit price, which is the price to sell an asset
or transfer a liability. The exit price may or may not equal the transaction price and the exit price objective applies regardless of a companys intent or ability to sell the asset or transfer the liability at the measurement date. The Company
currently measures fair value using the approximate mid-point of the bid and ask prices. Upon adoption of SFAS 157, the Company will measure fair value based on the bid or ask price for its price risk management assets and liabilities in accordance
with the exit price objective.

##### Table of Contents

The provisions of SFAS 157 are to be applied prospectively, except for the initial effect on three
specific items: (1) changes in fair value measurements of existing derivative financial instruments measured initially using the transaction price presumption under EITF 02-3, (2) existing hybrid financial instruments measured initially at
fair value using the transaction price, and (3) blockage factor discounts. Adjustments to these items required under SFAS 157 are to be recorded as a transition adjustment to beginning retained earnings in the year of adoption.

Upon adoption, the Company recognized a gain of approximately $1 million as a cumulative-effect adjustment to accumulated deficit, net of income tax on
January 1, 2008. The cumulative-effect adjustment relates entirely to the recognition of inception gains and losses formerly deferred under EITF 02-3.

On February 15, 2007, the FASB issued SFAS 159, which permits an entity to measure many financial instruments and certain other items at fair value by electing a fair value option. Once elected, the fair value
option may be applied on an instrument by instrument basis, is irrevocable and is applied only to entire instruments. SFAS 159 also requires companies with trading and available-for-sale securities to report the unrealized gains and losses for which
the fair value option has been elected within earnings for the period presented. SFAS 159 is effective at the beginning of the first fiscal year after November 15, 2007. The Company adopted SFAS 159 on January 1, 2008. The adoption of
SFAS 159 did not have a material effect on the Companys statements of operations, financial position or cash flows as the Company did not elect the fair value option for any of its financial instruments.

On April 30, 2007, the FASB issued FSP FIN 39-1, which amended FIN 39, to indicate that the following fair value amounts could be offset
against each other if certain conditions of FIN 39 are otherwise met: (a) those recognized for derivative instruments executed with the same counterparty under a master netting arrangement and (b) those recognized for the right to
reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) arising from the same master netting arrangement as the derivative instruments. In addition, a reporting entity is not precluded from offsetting the
derivative instruments if it determines that the amount recognized upon payment or receipt of cash collateral is not a fair value amount. FSP FIN 39-1 is effective at the beginning of the first fiscal year after November 15, 2007. The
adoption of FSP FIN 39-1 requires retrospective application for all financial statements presented as a change in accounting principle. The Company adopted FSP FIN 39-1 on January 1, 2008, and elected to continue to net the price risk
management assets and liabilities subject to master netting agreements. The Company will reflect the adoption of FSP FIN 39-1 in its consolidated financial position at March 31, 2008, and reclassify amounts at December 31, 2007, to be
consistent with the March 31, 2008, presentation. The adoption of FSP FIN 39-1 has no effect on the Companys consolidated statements of operations or cash flows.

Services and Risk Management Agreements with Affiliates

Historically, the Company provided energy marketing and fuel procurement services through Mirant Energy Trading to the following affiliates: Mirant Las
Vegas, Mirant Sugar Creek, Shady Hills, West Georgia and Mirant Wichita Falls. Mirant Wichita Falls was sold by Mirant in the second quarter of 2006. On May 1, 2007, Mirant completed the sale of the other four affiliates. For the years ended
December 31, 2007, 2006 and 2005, the total energy marketing costs were $47 million, $45 million and $54 million, respectively. For the years ended December 31, 2007, 2006 and 2005, the Company recorded a reduction to operations and
maintenance of approximately $1 million, $6 million and $8 million, respectively, related to the allocation of costs to affiliates. Subsequent to the sale of these affiliates, the Company no longer recognizes a reduction to operations and
maintenance associated with providing services to these affiliates.

Administration Arrangements with Mirant Services

Substantially all of Mirants corporate overhead costs are allocated to Mirants operating subsidiaries. For the years ended December 31,
2007, 2006 and 2005, the Company incurred approximately $125 million, $132 million and $133 million, respectively, in costs under these arrangements, which are included in operations and maintenanceaffiliate in the accompanying
consolidated and combined statements of operations.

The Companys allocation of Mirants overhead costs has increased as a
result of the recent disposition of Mirants Philippine and Caribbean businesses and six U.S. natural gas-fired facilities.

Restructuring
Charges

For the years ended December 31, 2007 and 2006, the Company recorded restructuring charges of $1 million and for the
year ended December 31, 2005, the Company recorded $3 million of severance costs and other charges, which are included in operations and maintenanceaffiliate in the accompanying consolidated and combined statements of operations. The
severance costs and other employee termination-related charges associated with the restructuring at the Companys locations were paid by Mirant Services and billed to the Company and are included in the amounts disclosed above for management,
personnel and services.

Notes Payable to Affiliate

During the pendency of the Chapter 11 proceedings, the Company and certain of its subsidiaries and Mirant and certain of its subsidiaries (excluding the Company and its subsidiaries) participated in separate
intercompany cash management programs whereby cash balances at the respective participating subsidiaries were transferred to central concentration accounts to fund working capital and other needs of the respective participants. At December 31,
2007 and 2006, the Company had current notes payable to affiliate of $6 million and $13 million, respectively, arising out of the balances owed by Mirant Zeeland under Mirants pre-emergence cash management program and by Mirant NY-Gen
under its pre-emergence debtor in possession facility with Mirant Americas. The Company incurred interest expense-affiliate of $1 million for the year ended December 31, 2007, and $23 million for the year ended December 31, 2005. Interest
expense-affiliate for the year ended December 31, 2006, was less than $1 million.

Payable to Mirant Americas Pursuant to the Plan

Mirant North America, the Companys wholly-owned subsidiary, was required to pay $250 million to Mirant Americas within five
days of the effective date of the Plan in return for Mirants contribution of its interest in the following: Mirant Americas Energy Marketing, Mirant Americas Development, Inc., Mirant Americas Production Company, Mirant Americas Energy
Capital, LLC, Mirant Americas Energy Capital Assets, LLC, Mirant Americas Development Capital, LLC, Mirant Americas Retail Energy Marketing, LP, and Mirant Americas Gas Marketing, I-XV, LLCs. This amount was paid in
January 2006.

Mirant Letters of Credit

Mirant posted pre-petition letters of credit and a guarantee on behalf of Mirant Mid-Atlantic to provide for the rent payment reserve required in connection with Mirant Mid-Atlantics lease obligations in the
event that it was unable to pay its lease payment obligations. On January 3, 2006, as part of the settlement of disputes in respect of the Mirant Mid-Atlantic leveraged leases and the Companys emergence from bankruptcy, Mirant North
America posted a $75 million letter of credit for rent payment reserve obligations under the Mirant Mid-Atlantic leveraged leases. Upon the posting of the letter of credit, the trustee under the leveraged leases returned $56 million of cash
collateral to Mirant Mid-Atlantic.

Mirant posted a post-petition letter of credit in the amount of $5 million on behalf of Mirant Texas,
LP (Mirant Texas) as of December 31, 2004, related to a tolling agreement. This post-petition letter of credit was set to expire in January 2006. Upon emergence from bankruptcy, Mirant North America replaced this post-petition
letter of credit with a letter of credit issued under its senior secured credit facilities. The letter of credit expired in February 2007.

Prior to 2005, Mirant entered into pre-petition letters of credit to support the Companys asset management activities. In September 2005, several of these letters of credit were drawn in the amount of $39 million. In
January 2006, the remaining pre-petition letter of credit of $7 million was drawn in full. In addition, Mirant entered into post-petition letters of credit to support its asset management activities. In January 2006, letters of credit from
the Mirant North America senior secured credit facilities replaced the eleven post-petition letters of credit outstanding at December 31, 2005. See Liquidity and Capital Resources Cash Collateral and Letters of Credit for details on
letters of credit outstanding at December 31, 2007.

Series A Preferred Shares in Mirant Americas

Pursuant to the Plan, Mirant Americas was required to make capital contributions to Mirant Mid-Atlantic for the purpose of funding future environmental
capital expenditures. These capital contributions were made in the form of mandatorily redeemable Series A Preferred Shares, and are reflected as preferred stock in affiliate in the accompanying consolidated balance sheets at December 31,
2007 and 2006. On June 30, 2007, Mirant Americas was required to redeem $5 million in preferred stock held by Mirant Mid-Atlantic, which was completed on July 2, 2007.

The Series A Preferred Shares have a Scheduled Redemption Date at a Specified Redemption Amount as follows (in millions):



|     |  |   |

|     |  |   |    
|     |  | $ | 260
|     |  |   |    

The redemption of any of the Series A Preferred Shares on any Scheduled Redemption Date shall
be deferred to the extent that Mirant Mid-Atlantic has not incurred prior to the Scheduled Redemption Date, or does not reasonably expect to incur within 180 days of such Scheduled Redemption Date, expenditures with respect to the installation of
control technology related to environmental capital expenditures at facilities owned or leased by Mirant Mid-Atlantic. Any amounts so deferred shall be added to the amount of Series A Preferred Shares to be redeemed on the next Scheduled

Preferred Shares are recorded at a fair value of $126 million and $118 million as a component of equity in the Companys consolidated balance sheets at December 31, 2007 and 2006, respectively. The fair value was determined using a
discounted cash flow method based on the expected redemption date and the liquidation preference amount using a 6.21% discount rate. For years ended December 31, 2007 and 2006, the Company recorded $8 million and $7 million respectively,
in preferred stock in affiliate and members interest in the consolidated balance sheets related to the amortization of the discount on the preferred stock in Mirant Americas.

4.    Financial Instruments

Commodity Financial Instruments

The Company manages the risks around fuel supply and power to be generated from its physical asset positions. Mirant manages the price risk associated
with asset management activities through a variety of methods. Mirants Risk Management Policy requires that asset management activities are restricted to only those activities that are risk-reducing in nature. In addition, the Company, through
its proprietary trading and fuel oil management activities, attempts to achieve incremental returns by entering into energy contracts where it has specific market expertise or physical asset positions. Proprietary trading and fuel oil management
activities increase risk and expose the Company to risk of loss if prices move differently than expected.

Mirant Americas Generation
enters into a variety of derivative financial and physical instruments to manage its exposure to the prices of the fuel it acquires for generating electricity, as well as the electricity that it sells. These include contractual agreements, such as
forward purchase and sale agreements, futures, swaps and option contracts. Futures are traded on national exchanges and swaps are typically traded in OTC financial markets. Option contracts are traded on both a national exchange and in OTC financial
markets. These contractual agreements have varying terms, notional amounts and durations, or tenors, which range from a few days to a number of years, depending on the instrument. As part of its proprietary trading activities, the Company is exposed
to certain market risks in an effort to generate gains from changes in market prices by entering into derivative instruments, including exchange-traded and OTC contracts, as well as other contractual arrangements.

Derivative instruments are recorded at their estimated fair value in the Companys accompanying consolidated balance sheets as price risk management
assets and liabilities except for a limited number of transactions that qualify for the normal purchase or normal sale exception election that allows accrual accounting treatment. Changes in the fair value and settlements of electricity derivative
financial instruments are reflected in operating revenue and changes in the fair value and settlements of fuel derivative contracts are reflected in cost of fuel and other products in the accompanying consolidated and combined statements of
operations. As of December 31, 2007 and 2006, the Company does not have any derivative instruments for which hedge accounting has been elected.

##### Table of Contents

Trading rights are intangible assets recognized in connection with asset purchases that represent the
Companys ability to generate additional cash flows by incorporating the Companys trading activities with the acquired generating facilities.

Development rights represent the right to expand capacity at certain acquired generating facilities. The existing infrastructure, including storage facilities, transmission interconnections and fuel delivery systems
and contractual rights acquired by the Company provide the opportunity to expand or repower certain generating facilities.

Emissions
allowances recorded in intangible assets relate to emissions allowances granted for owned generating facilities that were projected at the time of acquisition to be in excess of those required to offset physical emissions and emissions allowances
granted for the leasehold baseload units at the Morgantown and Dickerson facilities.

Emissions allowances granted by the EPA that were
projected at the time of acquisition to be required to offset physical emissions for owned assets are recorded within property, plant and equipment, net on the consolidated balance sheets.

Amortization expense was approximately $8 million for the years ended December 31, 2007, 2006 and 2005. Assuming no future acquisitions,
dispositions or impairments of intangible assets, amortization expense is estimated to be approximately $9 million for each of the next five years.

Impairments on Assets Held and Used

In accordance with SFAS 144, an asset classified as held and used shall be
tested for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. An asset impairment charge must be recognized if the sum of the undiscounted expected future cash flows from
a long-lived asset is less than the carrying value of that asset. The amount of any impairment charge is calculated as the excess of the carrying value of the asset over its fair value. Fair value is estimated based on the discounted future cash
flows from that asset or determined by other valuation techniques.

Year Ended December 31, 2007

Background

Mirant Lovett has been in ongoing
discussions with the NYSDEC and the New York State Office of the Attorney General regarding environmental controls at the Lovett generating facility in New York. On June 11, 2003, Mirant New York, Mirant Lovett and the State of New York entered
into a consent decree (the 2003 Consent Decree). Under the terms of the 2003 Consent Decree, Mirant Lovett was required to install certain environmental controls on unit 5 of the Lovett facility, convert unit 5 to operate
exclusively on natural gas, or discontinue operation of unit 5 by April 30, 2007. The 2003 Consent Decree also required that certain environmental controls be installed on unit 4 by April 30, 2008, or operation of unit 4 had
to be discontinued.

On May 10, 2007, Mirant Lovett entered into an amendment to the 2003 Consent Decree with the State of New York
that switched the deadlines for shutting down units 4 and 5 so that the deadline for compliance by unit 5 was extended until April 30, 2008, and the deadline for unit 4 was shortened. Unit 4 discontinued operation as of May 7,
2007. In addition, unit 3 discontinued operation because it was uneconomic for the unit to continue to run.

On May 8, 2007,
Mirant New York, Mirant Lovett, Mirant Bowline and Hudson Valley Gas also entered into an agreement (the Tax Assessments Agreement) with the Town of Stony Point, the Town of Haverstraw and the Village of Haverstraw to set the assessed
values for the Lovett and Bowline facilities and the pipeline owned by Hudson Valley Gas for 2007 and 2008 for property tax purposes at the values established for 2006 under a settlement agreement entered into by the Mirant entities and those taxing
authorities in December 2006.

The Bankruptcy Court approved the amendment to the 2003 Consent Decree and the Tax Assessments Agreement
on May 10, 2007. The United States District Court for the Southern District of New York approved the amendment to the 2003 Consent Decree on May 11, 2007.

On October 20, 2007, Mirant Lovett submitted notices of its intent to discontinue operations of unit 5 of the Lovett generating facility as of midnight on April 19, 2008, to the New York Public Service
Commission, the NYISO, Orange and Rockland and several other potentially affected transmission and distribution companies in New York.

In
its impairment analysis of the Lovett generating facility in prior periods, the Company assumed multiple scenarios, including the operation of all units of the Lovett facility beyond April 2008. Entering into the amendment to the 2003 Consent
Decree and the Tax Assessments Agreement prompted management to test for recoverability of the Lovett facility under SFAS 144 in the second quarter of 2007.

Assumptions and Results

The Companys assessment of Lovett under SFAS 144 in the second quarter of 2007 involved
developing two scenarios for the future expected operation of the Lovett facility. The first scenario considered was the shutdown of unit 5 by April 30, 2008, in accordance with the amendment to the 2003 Consent Decree. The Company also
considered a second scenario that assumed operation of unit 5, utilizing coal as the primary fuel source, through 2012 to allow the Lovett facility to continue to contribute to the reliability of the electric system of the State of New York.
Property taxes under both scenarios were assumed at the assessed levels specified in the Tax Assessments Agreement for those periods. Additionally, both scenarios included an estimated cost for demolition of the facility to reduce future property
taxes, a value for the land on which the facility operates and the sale of previously granted emissions allowances for periods beyond the shutdown date. For purposes of measuring an impairment loss, a long-lived asset or assets must be grouped at
the lowest level of independent identifiable cash flows. All of the units at Mirant Lovett are viewed as one group. As required under SFAS 144, the assessment did not include the value of new generating capacity that could potentially be constructed
at the current Lovett facility site.

As a result of this assessment, in the second quarter of 2007, the Company recorded an impairment
loss of $175 million to reduce the carrying value of the Lovett facility to its estimated fair value. The carrying value of the Lovett facility prior to the impairment was approximately $185 million. The remaining depreciable life for the
Lovett facility was also adjusted to April 30, 2008, based on the high likelihood of a shutdown of unit 5 on that date.

Year Ended
December 31, 2006

In 2006, the Companys assessment of the Bowline unit 3 suspended construction project resulted in
the conclusion that the Bowline unit 3 project as configured and permitted was not economically viable. As a result of this conclusion, the Company determined the estimated value of the equipment and project termination liabilities. At
December 31, 2006, the carrying value of the development and construction costs for Bowline unit 3 exceeded the estimated undiscounted cash flows from the abandonment of the project. The Company recorded an impairment of $120 million,
which is reflected in impairment losses on the consolidated statement of operations for the year ended December 31, 2006.

Mirant Americas Generation Senior Notes

In 2006, Mirant Americas Generation reinstated $1.7 billion of senior notes maturing in 2011, 2021 and 2031. The reinstated senior notes are
senior unsecured obligations of Mirant Americas Generation and are not recourse to any subsidiary or affiliate of Mirant Americas Generation. In the fourth quarter of 2007, Mirant purchased and retired $39 million of Mirant Americas Generation
senior notes due in 2011.

Mirant North America Senior Secured Credit Facilities

Mirant North America, a wholly-owned subsidiary of the Company, entered into senior secured credit facilities in January 2006, which are comprised
of an $800 million senior secured revolving credit facility and a senior secured term loan with an initial principal balance of $700 million amortized to $555 million as of December 31, 2007. At the closing, $200 million drawn under
the senior secured term loan was deposited into a cash collateral account to support the issuance of up to $200 million of letters of credit. At December 31, 2007, there were approximately $199 million of letters of credit outstanding
under the senior secured term loan and approximately $91 million of letters of credit outstanding under the $800 million senior secured revolving credit facility. At December 31, 2007, a total of $710 million was available under the senior
secured revolving credit facility and the senior secured term loan for cash draws or for the issuance of letters of credit.

In addition to
the quarterly installments of $1.75 million, Mirant North America is required to prepay a portion of the outstanding senior secured term loan principal balance once a year. The prepayment is based on an adjusted EBITDA calculation that determines
excess free cash flows, as defined in the loan agreement. At December 31, 2007, the current estimate of the mandatory principal prepayment of the term loan in the first quarter of 2008 is approximately $132 million. This amount has been
reclassified from long-term debt to current portion of long-term debt at December 31, 2007.

The senior secured credit facilities are
senior secured obligations of Mirant North America. In addition, certain subsidiaries of Mirant North America (not including Mirant Mid-Atlantic and its respective subsidiaries and Mirant Energy Trading) have jointly and severally guaranteed, as
senior secured obligations, the senior secured credit facilities. The senior secured credit facilities are nonrecourse to any other Mirant entities, including Mirant Americas Generation.

Mirant North America Senior Notes

In December 2005, Mirant North America issued senior notes in an aggregate principal amount of $850 million that bear interest at 7.375% and
mature on December 31, 2013. The original senior notes were issued in a private placement and were not registered with the SEC. The proceeds of the original senior notes offering initially were placed in escrow pending the emergence of Mirant
North America from bankruptcy. The proceeds were released from escrow in connection with Mirant North Americas emergence from bankruptcy and the closing of the senior secured credit facilities.

In connection with the issuance of the original senior notes, Mirant North America entered into a registration rights agreement under which it agreed to
complete an exchange offer for the original senior notes. On June 29, 2006, Mirant North America completed its registration under the Securities Act of $850 million of the senior notes and initiated the exchange offer. The exchange offer was
completed on August 4, 2006, with $849.965 million of the outstanding original senior notes being tendered for the senior notes. The terms of the senior notes are identical in all material respects to the terms of the original senior notes,
except that the senior notes are registered under the Securities Act and generally are not subject to transfer restrictions or registration rights.

Interest on the notes is payable on each June 30 and December 31. The senior notes are senior unsecured obligations of Mirant North America. In addition, certain subsidiaries of Mirant North America (not including Mirant
Mid-Atlantic and its subsidiaries and Mirant Energy Trading) have jointly and severally guaranteed, as senior unsecured obligations, the senior notes. The senior notes are nonrecourse to any other Mirant entities, including Mirant Americas
Generation. The notes are redeemable at the option of Mirant North America, in whole or in part, at any time prior to December 31, 2009, at a price equal to 100% of the principal amount, plus accrued and unpaid interest, plus a make-whole
premium. At any time on or after December 31, 2009, Mirant North America may redeem the notes at specified redemption prices, together with accrued and unpaid interest, if any, to the date of redemption. At any time prior to December 31,
2008, Mirant North America may redeem up to 35% of the original principal amount of the notes with the proceeds of certain equity offerings at a redemption price of 107.375% of the principal amount of the notes, together with accrued and unpaid
interest, if any, to the date of redemption. Under the terms of the notes, the occurrence of a change of control will be a triggering event requiring Mirant North America to offer to purchase all or a portion of the notes at a price equal to 101% of
their principal amount, together with accrued and unpaid interest, if any, to the date of purchase. In addition, certain asset dispositions or casualty events will be triggering events which may require Mirant North America to use the proceeds from
those asset dispositions or casualty events to make an offer to purchase the notes at 100% of their principal amount, together with accrued and unpaid interest, if any, to the date of purchase if such proceeds are not otherwise used, or committed to
be used, within certain time periods, to repay senior secured indebtedness, to repay indebtedness under the senior secured credit facilities (with a corresponding reduction in commitments) or to invest in capital assets related to its business.

Debt Maturities

North Americas required payments of its senior secured term loan based on its EBITDA.

Capital Leases

Long-term debt includes a capital lease by Mirant Chalk Point. At December 31, 2007 and 2006, the current portion of the long-term debt under this
capital lease was $3 million. The amount outstanding under the capital lease, which matures in 2015, is $30 million with an 8.19% annual interest rate. This lease is of an 84 MW peaking electric power generating facility. Depreciation expense
related to this lease was approximately $2 million for each of the years ended December 31, 2007, 2006 and 2005. The principal payments under this lease are approximately $3 million in 2008 through 2010, $4 million in 2011 through 2012 and
$13 million thereafter. The gross amount of assets under the capital lease, recorded in property, plant and equipment, net as of December 31, 2007 and 2006, was $24 million. The related accumulated depreciation was $12 million and $10
million as of December 31, 2007 and 2006, respectively.

Sources of Funds and Capital Structure

The principal sources of liquidity for the Companys future operations and capital expenditures are expected to be: (1) existing cash on hand
and cash flows from the operations of the Companys subsidiaries; (2) letters of credit issued or borrowings made under Mirant North Americas $800 million senior secured revolving credit facility; (3) $200 million
letter of credit capacity available under Mirant North Americas senior secured term loan; and (4) proceeds from the redemption of preferred shares issued by Mirant Americas to Mirant Mid-Atlantic and the Company to fund capital
expenditures and support the refinancing of the Companys senior notes due in 2011.

The Company and its subsidiary Mirant North
America are holding companies and, as a result, they are dependent upon dividends, distributions and other payments from their respective subsidiaries to generate the funds necessary to meet their obligations. The ability of certain of the
Companys subsidiaries to pay dividends and make distributions is restricted under the terms of their debt or other agreements. In particular, a substantial portion of the cash from the Companys operations is generated by Mirant
Mid-Atlantic. The Mirant Mid-Atlantic leveraged leases contain a number of covenants, including limitations on dividends, distributions and other restricted payments. Under its leveraged leases, Mirant Mid-Atlantic is not permitted to make any
dividends, distributions and other restricted payments unless: (1) it satisfies the fixed charge coverage ratio on a historical basis for the last period of four fiscal quarters; (2) it is projected to satisfy the fixed charge coverage
ratio for the next two periods of four fiscal quarters; and (3) no significant lease default or event of default has occurred and is continuing. In the event of a default under the leveraged leases or if the restricted payments test is not
satisfied, Mirant Mid-Atlantic would not be able to distribute cash. Based on the Companys calculation of the fixed charge coverage ratios under the leveraged leases as of December 31, 2007, Mirant Mid-Atlantic meets the required 1.7 to
1.0 ratio for restricted payments, both on a historical and projected basis.

The Companys subsidiary Mirant North America is an
intermediate holding company and the parent of the Companys operating subsidiaries, including Mirant Mid-Atlantic. Mirant North America incurred certain indebtedness pursuant to its senior notes and senior secured credit facilities secured by
the assets of Mirant North America and its subsidiaries (other than Mirant Mid-Atlantic and its subsidiaries and Mirant Energy Trading). The indebtedness of Mirant North America includes certain covenants typical in such notes and credit facilities,
including restrictions on dividends, distributions and other restricted payments. Further, the notes and senior secured credit facilities include financial covenants that will exclude from the calculation the financial results of any subsidiary that
is unable to make distributions or pay dividends at the time of such calculation. Thus, the ability of Mirant Mid-Atlantic to make distributions to Mirant North America under the leveraged lease transaction could have a material effect on the
calculation of the financial covenants under the senior notes and senior secured credit facilities of Mirant North America and on its ability to make distributions to the Company.

The ability of the Company to pay its obligations is dependent on the receipt of dividends from Mirant
North America, capital contributions from Mirant and its ability to refinance all or a portion of those obligations as they become due.

7. Income Taxes

Several changes to the Companys tax posture occurred as a result of the Plan, including the conversion of certain of the
Companys regarded corporate entities to limited liability companies coupled with the liquidation and/or merger of these regarded corporate entities into other disregarded corporate entities for income tax purposes, and certain partnerships
owned by the regarded corporate entities were also liquidated and now form part of these disregarded entities for income tax purposes. The result of the plan effects eliminates the Companys recording of tax expense and benefit beginning
January 1, 2006, with respect to the liquidated regarded corporate entities. Furthermore, with respect to those liquidated regarded corporate entities, all previously existing deferred tax assets and liabilities were eliminated as of
December 31, 2005. In May 2007, Mirant New York, Inc. was converted to a limited liability company, resulting in the elimination of any existing deferred tax assets and liabilities related to Mirant New York.

Certain of the Companys other subsidiaries continue to exist as regarded corporate entities for income tax purposes including Hudson Valley Gas,
Mirant Kendall, and Mirant Special Procurement Inc. For those regarded corporate entities, the Company allocates current and deferred income taxes to each regarded corporate entity as if such entity were a single taxpayer utilizing the asset and
liability method to account for income taxes. To the extent the Company provides tax expense or benefit, any related tax payable or receivable to Mirant is reclassified to equity in the same period. As such $2 million was reclassified as a capital
contribution to members interest for the year ended December 31, 2006.

The amount and ultimate utilization of the Companys remaining NOLs will depend on several
factors, including the Companys future financial performance and certain Mirant tax elections. At December 31, 2006, Mirant considered it to be more likely than not that it would elect treatment under §382(l)(5). As a result of
further tax planning, Mirant made the decision to elect §382(l)(6) in its 2006 income tax return that was filed on September 15, 2007. As a result, the Companys deferred income tax items including pre-emergence NOLs are presented in
accordance with the §382(l)(6) treatment at December 31, 2007. This change had no net effect on the consolidated balance sheets or consolidated statements of operations because the increase in the deferred tax asset NOLs was equally offset
by an increase in the related deferred tax asset valuation allowance.

Under §382(l)(6), the Company will be subject to an annual
limitation on the use of the pre-emergence NOLs including the effect of net unrealized built-in gains. The NOLs under this election will not be subject to any previous adjustments for interest accrued on debt settled with stock as required under
§382(l)(5).

At December 31, 2007, the Company had $82 million of NOL carryforwards for federal income tax purposes expiring
from 2023 to 2027 and $82 million of NOL carryforwards for state income tax purposes with various expiration dates (based on the application of apportionment factors and other state limitations). These NOL carryforwards are available to offset
future federal and state income taxes.

SFAS No. 109 requires that a valuation allowance be established when it is more likely than
not that all or a portion of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences are deductible.
In making this determination, management considers all available positive and negative evidence affecting specific deferred tax assets, including the Companys past and anticipated future performance, the reversal of deferred tax liabilities,
the implementation of tax planning strategies and managements expectations of future reimbursements of NOL carryforwards from Mirant.

Objective positive evidence is necessary to support a conclusion that a valuation allowance is not needed for all or a portion of deferred tax assets when significant negative evidence exists. The Company continues to maintain its valuation
allowance against its deferred tax assets. As of December 31, 2007, the Companys deferred tax assets reduced by the valuation allowance are completely offset with its deferred tax liabilities. In 2007, 2006 and 2005, the Company
recognized changes in its valuation allowance of $(65) million, $(50) million and $(534) million, respectively, related to its net deferred tax assets.

Tax Uncertainties

The Company, through its parent Mirant, negotiated a settlement agreement with the Internal Revenue Service (IRS) for certain tax liabilities arising from their audit of the Companys federal income
tax returns for tax years the Company was a subsidiary of the Southern Company. This agreement resulted in an assessment of $14 million including interest. The Company has provided adequate tax provisions in prior years for the recognition of
this liability. As this liability represented an intercompany obligation to Mirant, the liability was resolved pursuant to the Plan of Reorganization with no distribution for such liability. Mirant has indemnified the Company with respect to this
obligation.

The Company adopted the provisions of FIN 48 on January 1, 2007. Prior to adoption of FIN 48, the Company
recognized contingent liabilities related to tax uncertainties when it was probable that a loss had occurred and the loss or range of loss could be reasonably estimated. The recognition of contingent losses for tax uncertainties required management
to make significant assumptions about the expected outcomes of certain tax contingencies. Upon adoption of FIN 48, the Company changed its method to recognize only liabilities for uncertain tax positions that are less than or subject to the
measurement threshold of the more-likely-than-not standard. As a result of the implementation of FIN 48, for continuing operations the Company recognized a decrease in accrued liabilities of $51 million. The additional tax benefit resulted
in an increase of the same amount to members interest. The unrecognized tax benefit as a result of adopting FIN 48 is an insignificant amount and would not materially affect the Companys effective tax rate if it were to be
recognized. The Company does not currently anticipate any significant changes to the amount of the unrecognized tax benefit absent changes in judgment about the realizability of its recognized or unrecognized tax benefits.

The unrecognized tax benefit included the review of tax positions relating to open tax years beginning in 1999 and continuing to the present. The
Companys major tax jurisdictions are U.S. federal and several state jurisdictions. For U.S. federal income taxes, all tax years prior to 2004 are closed and for state purposes the earliest open tax year is 1999. However, both the federal and
state NOL carryforwards from any closed year is subject to examination until the year that such NOL carryforwards are utilized and that year is closed for audit. The Companys tax provision continues to include an immaterial amount related to
the accrual for any penalties and interest subsequent to its adoption of FIN 48.

Pro Forma Income Tax Disclosures

The Company is not subject to income taxes except for those subsidiaries of the Company that are separate taxpayers. Mirant Americas and Mirant are
otherwise directly responsible for income taxes related to the Companys operations.

The following reflects a pro forma disclosure of
the income tax provision that would be reported if the Company was to be allocated income taxes related to its operations. Pro forma income tax provision attributable to income before tax would consist of the following (in millions):

Mirant elected in its 2006 tax return to reduce the income tax basis of its depreciable assets for
any cancellation of debt income that arises from Mirant making an Internal Revenue Code section § 382(l)(6) election. As a result, the Company has reduced the tax basis of its depreciable assets by recording a reduction to proforma property and
intangible assets of $49 million in 2007.

As a result of Mirants election of §382(l)(6) in its 2006 income tax return, the
Companys deferred income tax items including pre-emergence NOLs are presented in accordance with the §382(l)(6) treatment at December 31, 2007. Mirants election had no effect on the Companys pro forma net deferred tax
assets or pro forma income tax expense because the increase in the pro forma deferred tax asset NOLs was equally offset by an increase in the related pro forma deferred tax asset valuation allowance.

Under §382(l)(6), the Company will be subject to an annual limitation on the use of the
pre-emergence pro forma NOLs including the effect of net unrealized built-in gains. The pro forma NOLs under this election will not be subject to any previous adjustments for interest accrued on debt settled with Mirant stock as required under
§382(l)(5).

As of December 31, 2007, a portion of the Companys pro forma NOLs (approximately $78 million) is attributable
to excess tax deductions primarily related to bankruptcy transactions. The recognition of the pro forma tax benefit of these excess tax deductions, either through realization or reduction of the pro forma valuation allowance, would be an increase to
pro forma members interest. These pro forma NOLs will be the last utilized for financial reporting purposes.

The Company has not
provided a pro forma deferred tax liability with respect to the Companys investment in the Mirant Americas Preferred Stock discussed in Note 3, since the underlying transaction is disregarded for income tax purposes.

increase in tax benefits that would have been recognized upon adoption of FIN 48 is $86 million. The pro forma unrecognized tax benefit as a result of adopting FIN 48 is an insignificant amount and would not materially affect the
Companys pro forma effective tax rate if it were recognized. The Companys pro forma tax provision continues to include an immaterial amount related to the accrual for any pro forma penalties and interest subsequent to its adoption of
FIN 48.

8.    Asset Retirement Obligations

Effective January 1, 2003, the Company adopted SFAS 143, which requires an entity to recognize the fair value of a liability for an asset retirement obligation in the period in which it is incurred. Additionally,
effective December 31, 2005, the Company adopted FIN 47, which expands the scope of asset retirement obligations to be recognized to include asset retirement obligations that may be uncertain as to the nature or timing of settlement. Upon
initial recognition of a liability for an asset retirement obligation or a conditional asset retirement obligation, an entity shall capitalize an asset retirement cost by increasing the carrying amount of the related long-lived asset by the same
amount as the liability. Over time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the useful life of the related asset. Retirement obligations associated with long-lived assets included
within the scope of SFAS 143 and FIN 47 are those for which a legal obligation exists under enacted laws, statutes and written or oral contracts, including obligations arising under the doctrine of promissory estoppel.

The Company identified certain asset retirement obligations within its power generating facilities. These asset retirement obligations are primarily
related to asbestos abatement in facilities on owned or leased property and other environmental obligations related to fuel storage facilities, wastewater treatment facilities, ash disposal sites and pipelines.

Asbestos abatement is the most significant type of asset retirement obligation identified for recognition in the Companys adoption of FIN 47.
The EPA has regulations in place governing the removal of asbestos. Due to the nature of asbestos, it can be difficult to ascertain the extent of contamination in older facilities unless substantial renovation or demolition takes place. Therefore,
the Company incorporated certain assumptions based on the relative age and size of its facilities to estimate the current cost for asbestos abatement. The actual abatement cost could differ from the estimates used to measure the asset retirement
obligation. As a result, these amounts will be subject to revision when actual abatement activities are undertaken.

9.    Commitments and Contingencies

Mirant Americas Generation has made firm commitments to buy materials and services in connection with its ongoing operations and has made financial
guarantees relative to some of its investments.

Cash Collateral

In order to sell power and purchase fuel in the forward markets and perform other energy trading and marketing activities, the Company often is required
to provide trade credit support to its counterparties or make deposits with brokers. In addition, the Company often is required to provide cash collateral for access to the transmission grid to participate in power pools and for other operating
activities. In the event of default by the Company, the counterparty can apply cash collateral held to satisfy the existing amounts outstanding under an open contract.

The following is a summary of cash collateral posted with counterparties as of December 31, 2007 and 2006 (in millions):

Operating Leases

Mirant Mid-Atlantic leases the Morgantown and Dickerson baseload units and associated property through 2034 and 2029, respectively. Mirant Mid-Atlantic has an option to extend the leases. Any extensions of the
respective leases would be limited to 75% of the economic useful life of the facility, as measured from the beginning of the original lease term through the end of the proposed remaining lease term. The Company is accounting for these leases as
operating leases and recognizes rent expense on a straight-line basis. Rent expense totaled $96 million for the years ended December 31, 2007 and 2006, and $99 million for the year ended December 31, 2005, and is included in operations and
maintenance-nonaffiliate in the accompanying consolidated and combined statements of operations. As of December 31, 2007 and 2006, the Company has paid approximately $330 million and $314 million, respectively, of lease payments in excess of
rent expense recognized, which is recorded in prepaid rent on the consolidated balance sheets.

As of December 31, 2007, the total
notional minimum lease payments for the remaining terms of the leases aggregated approximately $2.1 billion and the aggregate termination value for the leases was approximately $1.4 billion and generally decreases over time. Mirant
Mid-Atlantic leases the Morgantown and the Dickerson baseload units from third party owner lessors. These owner lessors each own the undivided interests in these baseload generating facilities. The subsidiaries of the institutional investors who
hold the membership interests in the owner lessors are called owner participants. Equity funding by the owner participants plus transaction expenses paid by the owner participants totaled $299 million. The issuance and sale of pass through
certificates raised the remaining $1.2 billion needed for the owner lessors to acquire the undivided interests.

The pass through
certificates are not direct obligations of Mirant Mid-Atlantic. Each pass through certificate represents a fractional undivided interest in one of three pass through trusts formed pursuant to three separate pass through trust agreements between
Mirant Mid-Atlantic and U.S. Bank National Association (as successor in interest to State Street Bank and Trust Company of Connecticut, National Association), as pass through trustee. The property of the pass through trusts consists of lessor notes.
The lessor notes issued by an owner lessor are secured by that owner lessors undivided interest in the lease facilities and its rights under the related lease and other financing documents.

The Company has commitments under other operating leases with various terms and expiration dates. Minimum lease payments under non-cancelable operating
leases approximate $5 million in 2008, $4 million in each of 2009 and 2010, $3 million in 2011, $2 million in 2012 and $17 million thereafter.

Fuel Commitments

Fuel commitments primarily relate to long-term coal agreements and other fuel purchase agreements. As of December 31, 2007, the Companys total estimated fuel commitments were $506 million. In addition, the
Company has transactions for which commercial terms have been negotiated but for which contracts have not yet been executed. Individual transactions may or may not be binding prior to execution of a contract.

Long-Term Service Agreements

As of
December 31, 2007, the total estimated commitments under LTSAs associated with turbines were approximately $31 million. These commitments are payable over the terms of the respective agreements, which range from ten to twenty years. These
agreements have terms that allow for cancellation of the contracts by the Company upon the occurrence of certain events during the term of the contracts. Estimates for future commitments for the LTSAs are based on the stated payment terms in the
contracts at the time of execution. These payments are subject to an annual adjustment for inflation.

Other

Other represents the open purchase orders less invoices received related to open purchase orders for procurement of products and services purchased in
the ordinary course of business. These include construction, maintenance and labor activities at the Companys generating facilities.

Maryland
Healthy Air Act

Maryland Healthy Air Act commitments are contracts and open purchase orders related to capital expenditures that the
Company expects to incur to comply with the limitations for SO2 and NOx emissions under the Maryland Healthy Air Act.

Guarantees

Mirant generally conducts its business through various intermediate holding companies, including Mirant Americas Generation, and various operating
subsidiaries which enter into contracts as a routine part of their business activities. In certain instances, the contractual obligations of such subsidiaries are guaranteed by, or otherwise supported by, Mirant or another of its subsidiaries,
including expressed guarantees or letters of credit issued under the credit facilities of Mirant North America.

In addition, Mirant
Americas Generation and its subsidiaries enter into various contracts that include indemnification and guarantee provisions. Examples of these contracts include financing and lease arrangements, purchase and sale agreements, commodity purchase and
sale agreements, construction agreements, engagement agreements with vendors and other third parties. While the primary obligation of Mirant Americas Generation or a subsidiary under such contracts is to pay money or render performance, such
contracts may include obligations to indemnify the counterparty for damages arising from the breach thereof and, in certain instances, other existing or potential liabilities. In many cases, the maximum potential liability of the obligor cannot be
estimated, since some of the underlying agreements contain no limits on potential liability.

Upon issuance or modification of a guarantee,
the Company determines if the obligation is subject to initial recognition and measurement of a liability and/or disclosure of the nature and terms of the guarantee. Generally, guarantees of the performance of a third party are subject to the
recognition and measurement, as well as the disclosure provisions, of FIN 45. Such guarantees must initially be recorded at fair value, as determined in accordance with the interpretation. The Company did not have any guarantees that met the
recognition requirements under FIN 45 at December 31, 2007.

##### Table of Contents

Alternatively, guarantees between and on behalf of entities under common control are subject only to the
disclosure provisions of the interpretation. The Company must disclose information as to the term of the guarantee and the maximum potential amount of future gross payments (undiscounted) under the guarantee, even if the likelihood of a claim is
remote.

Letters of Credit

As of
December 31, 2007, Mirant North America and certain of its subsidiaries were contingently obligated for $290 million under letters of credit issued under its senior credit facilities, which includes $199 million letters of credit issued
pursuant to its senior secured term loan and $91 million letters of credit issued pursuant to its revolving credit facility. Most of these letters of credit are issued in support of the obligations of Mirant North America and its subsidiaries to
perform under commodity agreements, financing or lease agreements or other commercial arrangements. In the event of default by the contracting party, the counterparty can draw on a letter of credit to satisfy the existing amounts outstanding under
an open contract. A majority of these letters of credit expire within one year of issuance, and it is typical for them to be renewed on similar terms.

Following is a summary of letters of credit issued as of December 31, 2007 and 2006 (in millions):

Commercial Purchase and Sales Arrangements

In connection with the purchase and sale of fuel, emission allowances and energy to and from third parties with respect to the operation of its
subsidiaries generating facilities, Mirant North America may be required to guarantee a portion of the obligations of certain of its subsidiaries. These obligations may include liquidated damages payments or other unscheduled payments. The
majority of the guarantees are set to expire before the end of 2010, although the obligations of the issuer will remain in effect until all the liabilities created under the guarantee have been satisfied or no longer exist. As of December 31,
2007, Mirant North America and its subsidiaries were contingently obligated for a total of $93 million under such arrangements. The Company does not expect that Mirant North America will be required to make any material payments under these
guarantees.

Other Guarantees and Indemnifications

As of December 31, 2007, the Company has issued $62 million of guarantees of obligations that its subsidiaries may incur as a provision for construction agreements, equipment leases, and on-going litigation. The
Company does not expect that Mirant North America will be required to make any material payments under these guarantees.

The Company,
through its subsidiaries, participates in several power pools with RTOs. The rules of these RTOs require that each participant indemnify the pool for defaults by other members. Usually, the amount indemnified is based upon the activity of the
participant relative to the total activity of the pool and the amount of the default. Consequently, the amount of such indemnification by the Companys subsidiaries cannot be quantified.

On a routine basis in the ordinary course of business, Mirant North America and its subsidiaries indemnify financing parties and consultants or other
vendors who provide services. The Company does not expect that Mirant North America or any of the subsidiaries will be required to make any material payments under these indemnity provisions.

Because some of the guarantees and indemnities that the Companys subsidiary issues to third parties
do not limit the amount or duration of its obligations to perform under them, there exists a risk that Mirant North America may have obligations in excess of the amounts described above. For those guarantees and indemnities that do not limit the
liability exposure, the Company may not be able to estimate its potential liability until a claim is made for payment or performance, because of the contingent nature of these contracts.

Overview

The Company had no assets or liabilities held for sale at December 31, 2007. Assets and liabilities held for sale at December 31, 2006,
included discontinued operations and other assets that were disposed of in 2007. In the third quarter of 2006, Mirant commenced auction processes to sell six of its U.S. natural gas-fired facilities, including the Zeeland (903 MW) and
Bosque (546 MW) facilities.

The sale of the Zeeland and Bosque natural gas-fired facilities was completed on May 1, 2007.
In the third quarter of 2006, the Company recorded an impairment loss of $71 million to reduce the carrying value of the facilities held for sale to estimated fair value. In subsequent periods, the Company recorded reductions to the impairment
loss of approximately $63 million resulting from the sale process. As a result, the Company recognized a cumulative loss of $8 million related to the sale. The net proceeds to Mirant North America after transaction costs were
$524 million.

The Company completed the sale of Mirant NY-Gen on May 7, 2007, and recognized a gain of $8 million related
to the sale. The proceeds related to the sale were immaterial as a result of the transfer of the net liabilities of Mirant New York-Gen.

At December 31, 2006, assets and liabilities held for sale consisted of the facilities discussed above and certain ancillary equipment included in the sale of the Zeeland and Bosque natural gas-fired facilities.

The table below presents the components of the balance sheet accounts classified as assets and liabilities held for sale for the year ended

|14. | Litigation and Other Contingencies
|--- | ----------------------------------

The Company is
involved in a number of significant legal proceedings. In certain cases, plaintiffs seek to recover large and sometimes unspecified damages, and some matters may be unresolved for several years. The Company cannot currently determine the outcome of
the proceedings described below or the ultimate amount of potential losses and therefore has not made any provision for such matters unless specifically noted below. Pursuant to SFAS 5, management provides for estimated losses to the extent
information becomes available indicating that losses are probable and that the amounts are reasonably estimable. Additional losses could have a material adverse effect on the Companys consolidated and combined financial position, results of
operations or cash flows.

Environmental Matters

EPA Information Request. In January 2001, the EPA issued a request for information to Mirant concerning the implications under the EPAs NSR regulations promulgated under the Clean Air Act of past repair and
maintenance activities at the Potomac River facility in Virginia and the Chalk Point, Dickerson and Morgantown facilities in Maryland. The requested information concerned the period of operations that predates the Company subsidiaries
ownership and lease of those facilities. Mirant responded fully to this request. Under the APSA, Pepco is responsible for fines and penalties arising from any violation associated with operations prior to the acquisition or lease of the facilities
by subsidiaries of the Company. If a violation is determined to have occurred at any of the facilities, the Company subsidiary owning or leasing the facility may be responsible for the cost of purchasing and installing emissions control equipment,
the cost of which may be material. The Companys subsidiaries owning or leasing the Chalk Point, Dickerson and Morgantown facilities in Maryland are installing a variety of emissions control equipment on those facilities to comply with the
Maryland Healthy Air Act, but that equipment may not include all of the emissions control equipment that could be required if a violation of the EPAs NSR regulations is determined to have occurred at one or more of those facilities. If such a
violation is determined to have occurred after the Companys subsidiaries acquired or leased the facilities or, if occurring prior to the acquisition or lease, is determined to constitute a continuing violation, the Companys subsidiary
owning or leasing the facility at issue could also be subject to fines and penalties by the state or federal government for the period after its acquisition or lease of the facility, the cost of which may be material, although applicable bankruptcy
law may bar such liability for periods prior to January 3, 2006, when the Plan became effective for the Company and its subsidiaries that own or lease these facilities.

Morgantown Particulate Emissions NOV.    On March 3, 2006, Mirant Mid-Atlantic received a notice sent on behalf of the
MDE alleging that violations of particulate matter emissions limits applicable to unit 1 at the Morgantown facility occurred on nineteen days in June and July 2005. The notice advises that the potential civil penalty is up to $25,000 per day for
each day that unit 1 exceeded the applicable particulate matter limit. The letter further advises that the MDE has asked the Maryland Attorney General to file a civil suit under Maryland law based upon the alleged violations.

Morgantown SO2 Exceedances.    Mirant Mid-Atlantic received an NOV dated March 8, 2006, asserting that on three days in
June 2005 and January 2006, the Morgantown facility exceeded SO2 emissions limitations specified in its air permit. The NOV indicates that on two of those days the SO2 emissions limitation was exceeded by two different units of the
Morgantown facility each day. The NOV did not seek a specific penalty amount but noted that the violations identified could subject Mirant Mid-Atlantic to a civil penalty of up to $25,000 per day.

Morgantown Emissions Observation NOV.    On June 30, 2006, the MDE issued an NOV to Mirant Mid-Atlantic indicating that
it had failed to comply with the air permit for the Morgantown facility by operating the combustion turbines at the facility for more than 168 hours without performing an EPA Reference Method 9 observation of stack emissions for an 18-minute period.
The NOV did not seek a specific penalty amount but noted that the violation identified could subject Mirant Mid-Atlantic to a civil penalty of up to $25,000 per day.

Mirant Potomac River NAAQS Exceedance.    On March 23, 2007, the Virginia
DEQ issued an NOV to Mirant Potomac River alleging that it violated Virginias Air Pollution Control Law and regulations on February 23, 2007, by operating the Potomac River facility in a manner that resulted in a monitored exceedance in a
twenty-four hour period of the NAAQS for SO2. As noted in the NOV, Mirant Potomac River was operating on February 23, 2007, as directed by PJM in accordance with a DOE order during a scheduled outage of the Pepco transmission lines serving
Washington, D.C. The NOV asserts that plant operators did not implement appropriate actions to minimize SO2 emissions. The NOV did not seek a specific penalty amount but noted that the violations identified could subject Mirant Potomac River to
civil penalties of varying amounts under different provisions of the Virginia Code, including a potential civil fine of up to $100,000.

New York State Administrative Claim.    On January 24, 2006, the State of New York and the NYSDEC filed a notice of administrative claims in the Mirant Debtors Chapter 11 proceedings asserting a claim
seeking to require the Mirant Debtors to provide funding to the Companys subsidiaries owning generating facilities in New York to satisfy certain specified environmental compliance obligations. The State of New York cited various existing
outstanding matters between the State and the Companys subsidiaries owning generating facilities in New York related to compliance with environmental laws and regulations. The State of New York and the NYSDEC executed a stipulated order with
the Companys New York subsidiaries and the other Mirant Debtors to stay resolution of this administrative claim. That stipulated order was approved by the Bankruptcy Court on February 23, 2006. Although this administrative claim remains
stayed, the bulk of the existing outstanding matters upon which the claim was based have been separately resolved with the NYSDEC.

Riverkeeper Suit Against Mirant Lovett.    On March 11, 2005, Riverkeeper, Inc. filed suit against Mirant Lovett in the United States District Court for the Southern District of New York under the Clean
Water Act. The suit alleges that Mirant Lovett failed to implement a marine life exclusion system at its Lovett generating facility and to perform monitoring for the exclusion of certain aquatic organisms from the facilitys cooling water
intake structures in violation of Mirant Lovetts water discharge permit issued by the State of New York. The plaintiff requested the court to enjoin Mirant Lovett from continuing to operate the Lovett generating facility in a manner that
allegedly violates the Clean Water Act, to impose civil penalties of $32,500 per day of violation, and to award the plaintiff attorneys fees. Mirant Lovetts view is that it has complied with the terms of its water discharge permit, as
amended by a Consent Order entered June 29, 2004. On April 20, 2005, the district court approved a stipulation agreed to by the plaintiff and Mirant Lovett that stayed the suit until 60 days after the entry of the order by the
Bankruptcy Court confirming the plan of reorganization for Mirant Lovett became final and non-appealable, which stay expired in late 2007.

Lovett/Bowline SPDES Notices of Violation.    On March 8, 2007, Mirant Lovett and Mirant Bowline received NOVs from the NYSDEC alleging certain violations of their State Pollutant Discharge Elimination
System, (SPDES) permits. On April 6, 2007, the NYSDEC filed a complaint against Mirant Lovett and Mirant Bowline based on these allegations. The complaint seeks a penalty of $500,000. On December 31, 2007, Mirant Bowline
entered into a Consent Order with the NYSDEC that resolved the NOV issued to it. In the Consent Order, Mirant Bowline agreed to pay a fine of $50,000 and to fund an environmental benefit project in the amount of $250,000. Mirant Lovett is in
discussions with the NYSDEC to resolve the NOV issued to it and has not yet responded to the complaint filed by the NYSDEC.

Notices of
Intent to Sue for Alleged Violations of the Endangered Species Act.    Mirant and Mirant Delta have received two letters, one dated September 27, 2007, sent on behalf of the Coalition for a Sustainable Delta, four water
districts, and an individual and the second dated October 16, 2007, sent on behalf of San Francisco Baykeeper (collectively with the parties sending the September 27, 2007, letter, the Noticing Parties), providing notice that
the Noticing Parties intend to file suit alleging that Mirant Delta has violated, and continues to violate, the federal Endangered Species Act through the operation of its Contra Costa and Pittsburg generating facilities. The Noticing Parties
contend that the facilities use of water drawn from the Sacramento-San Joaquin Delta for cooling purposes results in harm to four species of fish listed as endangered species. The Noticing Parties assert that Mirant Deltas authorizations
to take (i.e., cause harm to) those species, a biological opinion

and incidental take statement issued by the National Marine Fisheries Service on October 17, 2002, for three of the fish species and a biological
opinion and incidental take statement issued by the United States Fish and Wildlife Service on November 4, 2002, for the fourth fish species, have not been complied with by Mirant Delta and no longer apply to permit the effects on the four fish
species caused by the operation of the Contra Costa and Pittsburg generating facilities. Following receipt of these letters, in late October 2007, Mirant Delta received correspondence from the U.S. Fish and Wildlife Service, the National Marine
Fisheries Service and the Army Corps of Engineers clarifying that Mirant Delta continued to be authorized to take the four species of fish protected under the federal Endangered Species Act. In a subsequent letter, the Coalition for a Sustainable
Delta also alleged violations of the National Environmental Policy Act and the California Endangered Species Act associated with the operation of Mirant Deltas facilities. Mirant Delta disputes the allegations made by the Noticing Parties. No
lawsuits have been filed to date, and San Francisco Baykeeper on February 1, 2008, withdrew its notice of intent to sue.

Chapter 11 Proceedings

On July 14, 2003, and various dates thereafter, Mirant Corporation and certain of its subsidiaries (collectively, the
Mirant Debtors), including the Company and its subsidiaries, filed voluntary petitions for relief under Chapter 11 of the Bankruptcy Code in the Bankruptcy Court. Mirant, the Company and most of the Mirant Debtors emerged from
bankruptcy on January 3, 2006, when the Plan became effective. The remaining Mirant Debtors, Mirant New York, Mirant Bowline, Mirant Lovett, Mirant NY-Gen and Hudson Valley Gas, emerged from bankruptcy on various dates in 2007. As of
December 31, 2007, approximately one million of the shares of Mirant common stock to be distributed under the Plan had not yet been distributed and have been reserved for distribution with respect to claims disputed by the Mirant Debtors that
have not been resolved. Under the terms of the Plan, to the extent unresolved claims are resolved now that the Company has emerged from bankruptcy, the claimants will receive the same pro rata distributions of Mirant common stock, cash, or both
common stock and cash as previously allowed claims.

To the extent the aggregate amount of the payouts determined to be due with respect to
disputed claims ultimately exceeds the amount of the funded claim reserve, Mirant would have to issue additional shares of common stock to address the shortfall, which would dilute existing Mirant stockholders, and Mirant and the Company would have
to pay additional cash amounts as necessary under the terms of the Plan to satisfy such pre-petition claims.

California and Western Power Markets

FERC Refund Proceedings Arising Out of California Energy Crisis.    High prices experienced in
California and western wholesale electricity markets in 2000 and 2001 caused various purchasers of electricity in those markets to initiate proceedings seeking refunds. Several of those proceedings remain pending either before the FERC or on appeal
to the United States Court of Appeals for the Ninth Circuit (the Ninth Circuit). The proceedings that remain pending include proceedings (1) ordered by FERC on July 25, 2001, (the FERC Refund Proceedings) to
determine the amount of any refunds and amounts owed for sales made by market participants, including Mirant Americas Energy Marketing, in the CAISO or the Cal PX markets from October 2, 2000, through June 20, 2001 (the Refund
Period), (2) ordered by FERC to determine whether there had been unjust and unreasonable charges for spot market bilateral sales in the Pacific Northwest from December 25, 2000, through June 20, 2001 (the Pacific Northwest
Proceeding), and (3) arising from a complaint filed in 2002 by the California Attorney General that sought refunds for transactions conducted in markets administered by the CAISO and the Cal PX outside the Refund Period set by the FERC
and for transactions between the DWR and various owners of generation and power marketers, including Mirant Americas Energy Marketing and subsidiaries of the Company. Various parties appealed FERC orders related to these proceedings to the Ninth
Circuit seeking review of a number of issues, including changing the Refund Period to include periods prior to October 2, 2000, and expanding the sales of electricity subject to potential refund to include bilateral sales made to the DWR and
other parties. While various of these appeals remain pending, the Ninth Circuit has ruled that the FERC should consider further whether to grant relief for sales of electricity made in the CAISO and Cal PX

markets prior to October 2, 2000, at rates found to be unjust, and, in the proceeding initiated by the California Attorney General, what remedies,
including potential refunds, are appropriate where entities, including Mirant Americas Energy Marketing, purportedly did not comply with certain filing requirements for transactions conducted under market based rate tariffs.

On January 14, 2005, Mirant and certain of its subsidiaries, including the Company (the Mirant Settling Parties), entered into a
Settlement and Release of Claims Agreement (the California Settlement) with PG&E, Southern California Edison Company, San Diego Gas and Electric Company, the CPUC, the DWR, the EOB and the Attorney General of the State of California
(collectively, the California Parties). The California Settlement was approved by the FERC on April 13, 2005, and became effective on April 15, 2005, upon its approval by the Bankruptcy Court. The California Settlement resulted
in the release of most of Mirant Americas Energy Marketings potential liability (1) in the FERC Refund Proceedings for sales made in the CAISO or the Cal PX markets, (2) in the Pacific Northwest Proceeding, and (3) in any
proceedings at the FERC resulting from the complaint filed in 2002 by the California Attorney General. Under the California Settlement, the California Parties and those other market participants who have opted into the settlement have released the
Mirant Settling Parties, including Mirant Americas Energy Marketing, from any liability for refunds related to sales of electricity and natural gas in the western markets from January 1, 1998, through July 14, 2003. Also, the California
Parties have assumed the obligation of Mirant Americas Energy Marketing to pay any refunds determined by the FERC to be owed by Mirant Americas Energy Marketing to other parties that do not opt into the settlement for transactions in the CAISO and
Cal PX markets during the Refund Period, with the liability of the California Parties for such refund obligation limited to the amount of certain receivables assigned by Mirant Americas Energy Marketing to the California Parties under the California
Settlement. The settlement did not relieve Mirant Americas Energy Marketing of liability for any refunds that the FERC determines it to owe (1) to participants in the Cal PX and CAISO markets that are not California Parties (or that did not
elect to opt into the settlement) for periods outside the Refund Period and (2) to participants in bilateral transactions with Mirant Americas Energy Marketing that are not California Parties (or that did not elect to opt into the settlement).

Resolution of the refund proceedings that remain pending before the FERC or that currently are on appeal to the Ninth Circuit could
ultimately result in the FERC concluding that the prices received by Mirant Americas Energy Marketing in some transactions occurring in 2000 and 2001 should be reduced. The Companys view is that the bulk of any obligations of Mirant Americas
Energy Marketing to make refunds as a result of sales completed prior to July 14, 2003, in the CAISO or Cal PX markets or in bilateral transactions either have been addressed by the California Settlement or have been resolved as part of Mirant
Americas Energy Marketings bankruptcy proceedings. To the extent that Mirant Americas Energy Marketings potential refund liability arises from contracts that were transferred to Mirant Energy Trading as part of the transfer of the
trading and marketing business under the Plan, Mirant Energy Trading may have exposure to any refund liability related to transactions under those contracts.

FERC Show Cause Proceeding Relating to Trading Practices.    On June 25, 2003, the FERC issued a show cause order (the Trading Practices Order) to more than 50 parties,
including Mirant Americas Energy Marketing and subsidiaries of the Company. The Trading Practices Order identified certain specific trading practices that the FERC indicated could constitute gaming or anomalous market behavior in violation of the
CAISO and Cal PX tariffs, and required sellers previously involved in transactions of those types to demonstrate why such transactions were not violations of the CAISO and Cal PX tariffs. On September 30, 2003, and December 19, 2003, the
Mirant entities filed with the FERC for approval of a settlement agreement (the Trading Settlement Agreement) entered into between certain Mirant entities and the FERC Trial Staff and an amendment to that agreement, under which Mirant
Americas Energy Marketing would pay $332,411 and the FERC would have an allowed unsecured claim in Mirant Americas Energy Marketings bankruptcy proceeding for $3.67 million to settle the show cause proceeding. The FERC approved the
Trading Settlement Agreement, as amended, on June 27, 2005, and the Bankruptcy Court approved it on August 24, 2005. Certain parties filed motions for rehearing with the FERC, which it denied on October 11, 2006. A party to the
proceeding has appealed the FERCs June 27, 2005, order to the Ninth Circuit.

Mirant Americas Energy Marketing Contract Dispute with Nevada Power.    On
December 5, 2001, Nevada Power Co. filed a complaint at the FERC seeking reformation of the purchase price of energy under a contract it had entered with Mirant Americas Energy Marketing, claiming that the prices under that contract were unjust
and unreasonable because, when it entered into the contract, western power markets were dysfunctional and non-competitive markets. On June 25, 2003, the FERC dismissed this complaint. Nevada Power appealed that dismissal to the United States
Court of Appeals for the Ninth Circuit, which on December 19, 2006, reversed the dismissal of the complaint and remanded the proceeding to the FERC. On September 25, 2007, the United States Supreme Court granted a petition for writ of
certiorari asking that it review that decision by the Ninth Circuit. The sales made under the contract with Nevada Power have been completed, and the Company expects that any refund claim related to that contract, if not now barred, will be
addressed in the Chapter 11 proceedings.

Mirant Americas Energy Marketing Contract Dispute with Southern California
Water.    On December 21, 2001, Southern California Water Company filed a complaint at the FERC seeking reformation of the purchase price of energy under a long-term contract it had entered with Mirant Americas Energy
Marketing, claiming that the prices under that contract were unjust and unreasonable because, when it entered the contract, western power markets were dysfunctional and non-competitive markets. The contract was for the purchase of 15 MWs during the
period April 1, 2001, through December 31, 2006. On June 25, 2003, the FERC dismissed this proceeding. Southern California Water appealed that dismissal to the United States Court of Appeals for the Ninth Circuit, which on
December 19, 2006, reversed the dismissal of the complaint and remanded the proceeding to the FERC. On September 25, 2007, the United States Supreme Court granted a petition for writ of certiorari asking that it review that decision by the
Ninth Circuit. Upon the transfer of the assets of the trading and marketing business to Mirant Energy Trading under the Plan, Mirant Energy Trading assumed Mirant Americas Energy Marketings contract obligations to Southern California Water
Company, including any potential refund obligations.

Maryland Public Service Commission Complaint to the FERC re PJM Offer Capping Rules

In certain market conditions, such as where congestion requires the dispatch of a generating facility that bid a higher price for
electricity than other available generating facilities, PJMs market rules (the Offer Capping Rules) limit the amount that the owner of a generating facility may bid to sell electricity from that facility to its incremental cost of
service to produce that electricity. As approved by the FERC, the Offer Capping Rules contain exemptions for generating facilities entering service during certain years (none of which are owned by the Company) and for generating facilities (some of
which are owned by the Company) that can relieve congestion arising at certain defined transmission interfaces. On January 15, 2008, the Maryland Public Service Commission (the MD PSC) filed a complaint with the FERC requesting that
the FERC remove all exemptions to the Offer Capping Rules during hours when the PJM market reflects potentially non-competitive conditions, as determined by the PJM Market Monitor. The complaint alleges that these exemptions to the Offer Capping
Rules likely result in higher market clearing prices for electricity in PJM, and higher revenues to the Company and the other owners of generation that are selling electricity, during the periods when the exemptions prevent the application of the
Offer Capping Rules to one or more generating facilities. The MD PSC requested that the FERC require a rerunning of the dispatch of the PJM energy markets without application of the exemptions to the Offer Capping Rules for each day from
January 15, 2008, through the date that the Commission grants the requested relief and that it require owners of generation to refund any revenues received in excess of the amounts that would have been received had the exemptions not been
applied.

In addition, the MD PSC alleged that PJM violated its tariff by not publicly disclosing since mid 2006 quarterly analyses
performed by the PJM Market Monitor of the potential for the exercise of market power by owners of generation during periods when market conditions caused the exemptions to the Offer Capping Rules to apply. The MD PSC requested the FERC to initiate
an investigation of whether owners of generation exercised market power during such periods, and, if so, to order refunds beginning as of September 8, 2006, or the first date that the FERC determines that PJM violated its tariff.

##### Table of Contents

The Company disputes the allegations made by the MD PSC in its complaint and intends to oppose the
complaint and the relief requested. If the FERC were to remove the exemptions to the Offer Capping Rules, and apply the removal retroactively from January 15, 2008, or an earlier date, PJM would have to rerun its day-ahead market from that date
forward to determine what prices would have resulted in the absence of the exemptions. Such a rerun of the PJM day-ahead market likely would result in refunds being owed by all sellers, including the Company, but the potential amount cannot be
quantified.

Other Legal Matters

The Company is involved in various other claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the
Companys financial position, results of operations or cash flows.



|15. | Settlements and Other Charges
|--- | -----------------------------

Pepco Litigation

In 2000, Mirant purchased power generating facilities and other assets from Pepco, including certain PPAs between Pepco and third parties.
Under the terms of the APSA, Mirant and Pepco entered into the Back-to-Back Agreement with respect to certain PPAs, including Pepcos long-term PPA with Panda-Brandywine, LP, under which (1) Pepco agreed to resell to Mirant all capacity,
energy, ancillary services and other benefits to which it is entitled under those agreements and (2) Mirant agreed to pay Pepco each month all amounts due from Pepco to the sellers under those agreements for the immediately preceding month
associated with such capacity, energy, ancillary services and other benefits. The Back-to-Back Agreement, which did not expire until 2021, obligated Mirant to purchase power from Pepco at prices that typically were higher than the market prices for
power.

Mirant assigned its rights and obligations under the Back-to-Back Agreement to Mirant Americas Energy Marketing. In the Chapter 11
cases of the Mirant Debtors, Pepco asserted that an Assignment and Assumption Agreement dated December 19, 2000, that included as parties Pepco and various of the Companys subsidiaries, caused the Companys subsidiaries that were
parties to the agreement to be jointly and severally liable to Pepco for various obligations, including the obligations under the Back-to-Back Agreement. The Mirant Debtors sought to reject the APSA, the Back-to-Back Agreement, and the Assignment
and Assumption Agreement. Under the Plan, the obligations of the Mirant Debtors under the APSA (including any other agreements executed pursuant to the terms of the APSA and found by a final court order to be part of the APSA), the Back-to-Back
Agreement, and the Assignment and Assumption Agreement were performed after January 3, 2006, by Mirant Power Purchase, whose performance was guaranteed by Mirant, pending resolution of the rejection motions.

On May 30, 2006, Mirant and various of its subsidiaries, including subsidiaries of the Company (collectively the Mirant Settling
Parties), entered into the Settlement Agreement with the Pepco Settling Parties. The Settlement Agreement could not become effective until it had been approved by the Bankruptcy Court and that approval order had become a final order no longer
subject to appeal. The Bankruptcy Court entered an order approving the Settlement Agreement on August 9, 2006. That order was appealed, but the appeal was dismissed by agreement of the parties in August 2007, and the Settlement Agreement
became effective August 10, 2007. The Settlement Agreement fully resolved the contract rejection motions that remained pending in the bankruptcy proceedings, as well as other matters disputed between Pepco and Mirant and its subsidiaries. The
Back-to-Back Agreement was rejected and terminated effective as of May 31, 2006, and the Assignment and Assumption Agreement was also rejected.

Under the Settlement Agreement, Mirant Power Purchase assumed the remaining obligations under the APSA, and Mirant has guaranteed its performance. With respect to the other agreements executed as part of the closing
of the APSA (the Ancillary Agreements) and other agreements between Pepco and subsidiaries of Mirant, including subsidiaries of the Company, the Mirant subsidiary that is a party to each agreement has assumed the agreement and Mirant has
guaranteed that subsidiarys performance. Mirant Power Purchases

obligations under the APSA do not include any obligations related to the Ancillary Agreements. The Settlement Agreement provides that a future breach of the
APSA or any Ancillary Agreement by a party to such agreement will not entitle the non-defaulting party to terminate, suspend performance under, or exercise any other right or remedy under or with respect to any of the remainder of such agreements.

The Settlement Agreement granted Pepco a claim against Old Mirant in Old Mirants bankruptcy proceedings that was to result in Pepco
receiving common stock of Mirant and cash having a value, after liquidation of the stock by Pepco, equal to $520 million. Shortly after the Settlement Agreement became effective, Mirant distributed approximately 14 million shares of Mirant
common stock from the shares reserved for disputed claims under the Plan to Pepco to satisfy its claim. The Mirant shares in the share reserve, including the shares distributed to Pepco, have been treated as issued and outstanding since Mirant
emerged from bankruptcy. Pepcos liquidation of those shares resulted in net proceeds of approximately $522 million and Pepco paid Mirant the amount in excess of $520 million.

New York Tax Proceedings

Mirant New York,
Mirant Bowline, Mirant Lovett, and Hudson Valley Gas (collectively with Mirant New York, Mirant Bowline and Mirant Lovett, the New York Companies) were the petitioners in various proceedings (the Tax Certiorari Proceedings)
initially brought in the New York state courts challenging the assessed values determined by local taxing authorities for the Bowline and Lovett generating facilities and a natural gas pipeline (the HVG Property) owned by Hudson Valley
Gas. Mirant Bowline had challenged the assessed value of the Bowline generating facility and the resulting local tax assessments for tax years 1995 through 2006. Mirant Bowline succeeded to rights held by Orange and Rockland for the tax years
prior to its acquisition of the Bowline facility in 1999 under its agreement with Orange and Rockland for the purchase of that facility. Mirant Lovett had challenged the assessed value of the Lovett facility for each of the years 2000 through
2006. Hudson Valley Gas had challenged the assessed value of the HVG Property for each of the years 2004 through 2006. As of December 31, 2006, Mirant Bowline and Mirant Lovett had not paid property taxes on the Bowline and Lovett generating
facilities that fell due in the period from September 30, 2003, through December 31, 2006, in order to preserve their respective rights to offset the overpayments of taxes made in earlier years against the sums payable on account of
current taxes. Hudson Valley Gas had not paid property taxes that fell due in the period from September 30, 2004, through December 31, 2006.

On December 13, 2006, Mirant and the New York Companies entered into a settlement agreement (the Tax Settlement Agreement) with the Town of Haverstraw (Haverstraw), the Town of Stony Point
(Stony Point), the Haverstraw-Stony Point Central School District (the School District), the County of Rockland (the County), the Village of Haverstraw (Haverstraw Village), and the Village of West
Haverstraw (West Haverstraw Village and collectively with Haverstraw, Stony Point, the School District, the County, and Haverstraw Village, the Tax Jurisdictions). The Tax Settlement Agreement was approved by the Bankruptcy
Court on December 14, 2006, and resolved all pending disputes regarding real property taxes between the New York Companies and the Tax Jurisdictions. Under the agreement, the New York Companies received total refunds of $163 million from the
Tax Jurisdictions and paid unpaid but accrued taxes to the Tax Jurisdictions of $115 million, resulting in the New York Companies receiving a net cash payment in the amount of $48 million. The refunds and unpaid taxes were paid in February 2007. The
$163 million of total refunds received by the New York Companies was recognized as a gain in the financial statements in the fourth quarter of 2006. In addition, the New York Companies had previously accrued a liability based upon the unpaid taxes
as billed by the Tax Jurisdictions. Due to the reductions of the unpaid taxes that occurred pursuant to the terms of the Tax Settlement Agreement, the New York Companies also recognized in the fourth quarter of 2006 a reduction of operating expenses
of approximately $23 million related to 2006 and a gain of approximately $71 million related to prior periods.

California Settlement

The California Settlement described in Note 14 in California and Western Power MarketsFERC Refund Proceedings Arising Out of California Energy Crisis included a provision that either (1) the
partially constructed Contra Costa 8 project, which was a planned 530 MW combined cycle generating facility, and related equipment (collectively, the CC8 Assets) were to be transferred to PG&E or (2) PG&E would receive
additional alternative consideration of $70 million (the CC8 Alternative Consideration). To fund the CC8 Alternative Consideration, PG&E received an allowed, unsecured claim in the bankruptcy proceedings against Mirant Delta that
resulted in a distribution to PG&E of cash and Mirant common stock with an aggregate value of approximately $70 million. PG&E was required to liquidate the common stock received as part of that distribution and place the net resulting amount
plus any cash received into an escrow account.

The California Settlement provided that if the transfer of the CC8 Assets to PG&E did
not occur on or before June 30, 2008, then the CC8 Alternative Consideration was to be paid to PG&E and the Mirant Settling Parties would retain the CC8 Assets. If PG&E closed on its acquisition of the CC8 Assets, the funds in the
escrow account were to be paid to Mirant Delta. The transfer of the CC8 Assets to PG&E was completed on November 28, 2006, and the $70 million escrow account was paid to Mirant Delta. The Company recognized in the fourth quarter of 2006 a
gain of $27 million for the amount by which the escrow account exceeded the carrying amount of the CC8 Assets. The gain was included in other income in the Companys consolidated and combined statements of operations.

|-------- | -----------------------

Inherent
Limitations in Control Systems

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute,
assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the
inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities
that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by
management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals
under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective
control system, misstatements resulting from error or fraud may occur and not be detected. As a result, our management, including the Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures,
or our internal control over financial reporting, will prevent all error and all fraud.

Effectiveness of Disclosure Controls and Procedures

As required by Exchange Act Rule 13a-15(b), our management, including our Chief Executive Officer and our Chief Financial
Officer, conducted an assessment of the effectiveness of the design and operation of our disclosure controls and procedures (as defined by Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of December 31, 2007. Based upon
this assessment, our management concluded that, as of December 31, 2007, the design and operation of these disclosure controls and procedures were effective.

Appearing as exhibits to this annual report are the certifications of the Chief Executive Officer and the Chief Financial Officer required in accordance with Section 302 of the Sarbanes-Oxley Act of 2002.

Managements Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined by
Rules 13a-15(f) under the Exchange Act). The Companys internal control framework and processes have been designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial
statements for external purposes in accordance with U.S. generally accepted accounting principles. Internal control over financial reporting includes those processes and procedures that:



| |  |  | pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | provide reasonable assurance that transactions are recorded properly to allow for the preparation of financial statements, in accordance with generally accepted
accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Companys assets that could have
a material effect on the consolidated and combined financial statements; and

Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we carried out an assessment of the effectiveness of our internal control over
financial reporting as of December 31, 2007. In conducting our assessment, management utilized the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal ControlIntegrated Framework.
Based on this assessment, management concluded that our internal control over financial reporting was effective as of December 31, 2007.

Changes
in Internal Controls

During the quarter ended December 31, 2007, there were no significant changes in Mirant Americas
Generations internal control over financial reporting or in other factors that could materially affect or is reasonably likely to affect such internal controls over financial reporting.

Audit Committee and Audit Committee Financial Expert

We do not have a separately designated
standing Audit Committee. Because Mirant Americas Generation is an indirect wholly-owned subsidiary of Mirant Corporation, the Board of Managers does not have independent members and therefore has not separately designated a member as a financial
expert.

Section 16(a) Beneficial Ownership Reporting Compliance

We do not have equity securities registered pursuant to Section 12 of the Exchange Act and therefore do not have officers with Section 16
reporting obligations.
