BECK] April 13, 2001 Mirant Americas Generation, Inc. 1155 Perimeter Center West Atlanta, Georgia 30338 Subject: Independent Engineer's Report on the Mirant Americas Generation, Inc. Facilities INTRODUCTION Presented herein is the report (the "Report") of our review and analyses of 73 generating units owned by subsidiaries and affiliates of Mirant Americas Generation, Inc. ("Mirant Generation") and located in the states of Maryland, Virginia, California, New York, Massachusetts, Texas, Indiana, and Wisconsin, as described in more detail herein (the "Mirant Generation Facilities"). A map showing the locations of the Mirant Generation Facilities is presented in Figure A-1. Neither our review, nor the accompanying financial projections, has included the five units comprising the Martha's Vineyard Facility nor Mirant Generation's 9 megawatt ("MW") ownership interest in the Wyman Facility. The Report represents a summary of our review and analyses. Additional detail regarding the Mirant Generation Facilities is available in the Supplement to the Independent Engineer's Report (the "Supplement"). The Supplement is publicly available on the Securities and Exchange Commission's EDGAR system as an exhibit to a current report on Form 8-K furnished by Mirant Corporation ("Mirant") pursuant to Regulation FD. The EDGAR system may be accessed at www.sec.gov. Mirant Generation is an indirect wholly-owned subsidiary of Mirant, formerly known as Southern Energy, Inc. Mirant Generation is expected to issue $600,000,000 of __% Senior Notes, Series A due 2006 (the "Series A Notes") and $600,000,000 of __% Senior Notes, Series B due 2011 (the "Series B Notes" and, together with the Series A Notes, the "Notes"). The Mirant Generation Facilities consist of steam-driven, coal-fired, gas-fired and oil-fired electric generating units, as well as hydroelectric facilities, diesels and combustion turbine ("CT") units fired by either gas or oil. The Mirant Generation Facilities are presented in this report according to geographic location. The Mirant Generation Facilities consist of the following facilities: (1) the Mid-Atlantic generating facilities (the "Mirant Mid-Atlantic Facilities"), which consist of the Chalk Point, Dickerson, Morgantown and Potomac River generating facilities; (2) the Mirant California generating facilities (the "Mirant California Facilities"), which consist of the Contra Costa, Pittsburg and Potrero generating facilities; (3) the Mirant New York generating facilities (the "Mirant New York Facilities"), which consist of the Bowline and Lovett generating facilities as well as certain hydroelectric facilities (the "Hydroelectric Facilities") and certain combustion turbines (the "NY CTs"); (4) the Mirant New England generating facilities (the "Mirant New England Facilities"), which consist of the Canal, Martha's Vineyard and Kendall generating facilities and an ownership interest in the Wyman generating facility; (5) the Mirant Texas generating facility (the "Mirant Texas Facility"), which consists of the Bosque generating facility; (6) the State Line Energy generating facility (the "State Line Facility"); and (7) the Mirant Wisconsin generating facility (the "Mirant Wisconsin Facility"), which consists of the Neenah generating facility. Four of the Mirant Generation Facilities currently sell at least a portion of their generation under various types of power purchase agreements. Certain other power purchase agreements have been assigned to other A-1 Mirant entities such that they do not impact the payment of interest on the Notes. One business unit sells thermal energy under a steam sales agreement. Fuel for the Mirant Generation Facilities is generally purchased under short-term contract. A summary of the Mirant Generation Facilities is presented in Table 1. As shown in Table 1, the Mirant Generation Facilities have a combined summer generating capability of 12,480 MW, of which 46 percent is gas-fired, 30 percent is coal-fired, 24 percent is oil-fired, and less than 1 percent is hydroelectric. Eighty-two percent of the Mirant Generation Facilities' summer generating capability is steam turbine technology, 2 percent is combined-cycle technology, and 15 percent is CT technology, with the remaining 1 percent made up of diesel and hydroelectric technology. With respect to dispatch type, 31 percent of the summer generating capability is projected to be dispatched to serve base-load, 48 percent to serve intermediate load, and 21 percent to serve peaking load requirements.

A-2 Figure A-1 Mirant Generation Facilities Facility Locations [MAP OMITTED] A-3 During the course of our review, we visited and made general field observations of the Mirant Generation Facilities and the sites of the Mirant Generation Facilities. The general field observations were visual, above-ground examinations of selected areas which we deemed adequate to comment on the existing condition of the sites but which were not in the level of detail necessary to reveal conditions with respect to geological or environmental conditions, the internal physical condition of any equipment, or the conformance with agreements, codes, permits, rules, or regulation of any party having jurisdiction with respect to the sites. We did not visit the sites of the Bosque or Neenah Facilities. In addition, we have reviewed: (1) the status of permits and approvals and compliance with those permits; (2) environmental assessment reports; (3) the historic and projected levels of production of the Mirant Generation Facilities; (4) the historic and projected operating and maintenance expenses of the Mirant Generation Facilities; (5) the projected revenues of the Mirant Generation Facilities; (6) historical operating records of the Mirant Generation Facilities; and (7) operating programs and procedures. Based on our review, we have prepared a projection of revenues and expenses of the Mirant Generation Facilities and interest coverage ratios, which are attached as Exhibits A-1 through A-9 to this Report (the "Projected Operating Results"). In developing the Projected Operating Results, we have relied upon a report by PA Consulting Group ("PA Consulting") attached as Annex B to the Offering Circular, of which this Report is a part, for projections of the Mirant Generation Facilities' electricity sales, revenues, and fuel costs. We have not reviewed PA Consulting's methodology and approach in its development of these projections but instead have based our reliance upon their previous experience in developing similar projections. MIRANT MID-ATLANTIC FACILITIES Description of the Facilities The Mirant Mid-Atlantic Facilities consist of generating units located at four separate facility sites in Maryland and Virginia, as well as other ancillary facilities. The generating units consist of the Chalk Point power plant located in Prince George's County, Maryland (the "Chalk Point Facility"); the Dickerson power plant located in Montgomery County, Maryland (the "Dickerson Facility"); the Morgantown power plant located in Charles County, Maryland (the "Morgantown Facility"); and the Potomac River power plant located in Alexandria, Virginia (the "Potomac River Facility"). Mirant Mid-Atlantic, LLC, an indirect wholly-owned subsidiary of Mirant, and its subsidiaries and affiliates (collectively, "Mirant Mid-Atlantic") own the Chalk Point Facility (except for a CT owned by the Southern Maryland Electric Cooperative ("SMECO") and the Potomac River Facility. Mirant Mid-Atlantic also owns or leases the Dickerson Facility and the Morgantown Facility. In addition, Mirant Mid-Atlantic owns the following assets and related facilities: (1) the Production Service Center (the "PSC"), which is an engineering and maintenance service facility; (2) a fuel oil delivery pipeline and associated pumping and storage facilities for supplying fuel oil to the Chalk Point and Morgantown Facilities (the "Piney Point Pipeline"); and (3) the Faulkner ash storage facility ("Faulkner"), the Brandywine ash storage facility ("Brandywine"), and the Westland ash storage facility ("Westland", and together with Faulkner and Brandywine, the "Ash Storage Facilities"). The Mirant Mid-Atlantic Facilities, the PSC, the Piney Point Pipeline, and the Ash Storage Facilities were purchased from Potomac Electric Power Company ("Pepco") in December 2000. The Chalk Point Facility The Chalk Point Facility is located approximately 45 miles southeast of Washington, DC on a 1,160-acre site at the confluence of the Patuxent River and Swanson Creek in Prince George's County, Maryland. The Chalk Point Facility is comprised of four conventional steam turbine units and seven simple-cycle CTs, with a total net summer generating capacity of 2,423 MW as listed in Table 2. Included in this amount is Mirant Mid-Atlantic's entitlement to the output of one on-site 84 MW CT that is owned by SMECO. The Chalk Point Facility is the largest of the Mirant Mid-Atlantic Facilities and provides base-load, intermediate and peaking generation and is capable of utilizing a variety of fuels. A-4 Table 2 Unit Characteristics Chalk Point Facility Summer Full Load In-Service Capacity Heat Rate Dispatch Unit Fuel Date (MW) (Btu/kWh) Type ---- ---- ---- ---- --------- ---- Units 1 & 2 Coal/Gas 1964/1965 683 9,350 Base-load Units 3 & 4 No. 6 Oil/Gas 1975/1981 1,224 10,140 Intermediate CT 1 No. 2 Oil 1967 18 12,300 Peaking CT 2 No. 2 Oil 1974 30 12,300 Peaking CTs 3 & 4 Gas/No. 2 Oil 1991/1991 170 12,300 Peaking CTs 5 & 6 Gas/No. 2 Oil 1991/1991 214 11,700 Peaking SMECO CT Gas/No. 2 Oil 1990 84 12,500 Peaking ----- Total 2,423 In addition, the Chalk Point Facility has certain common facilities shared by all units such as river water pumping stations, fuels receiving, storage and handling systems, water treatment systems, warehouses, maintenance shops, a chemistry laboratory, administrative offices, groundwater monitoring wells, and an electrical switchyard. The design and construction of electric utility generating units using pulverized coal, No. 6 residual oil, or natural gas to fire steam boilers has been common for many years, as has the firing of natural gas or No. 2 distillate oil in CTs. The Chalk Point Facility was designed utilizing the standard technologies available at the time it was built. Where it has proven economically desirable, or where regulatory changes have required, new technologies have been "backfit" into the Chalk Point Facility to improve operations, environmental compliance, and efficiencies. Major examples of this include the conversion of Chalk Point Units 1 and 2 to balanced draft operation and installation of new, more efficient precipitators in the early 1980s, provision of gas firing capability for Chalk Point Units 1 and 2 in the 1990s, and replacement of the control systems of Chalk Point Units 1 and 2. In general, Chalk Point Units 1 and 2 have been normally base-loaded, which is common for large, coal-fired units which are generally designed for this type of operation. The Chalk Point Units 3 and 4 have been generally used in intermediate service. Many large steam units were originally designed for base-load service and later converted to peaking service. Some of these converted units experienced thermal cycling damage such as cracking of major steam generator and turbine components, accelerated erosion of turbine components, and operational difficulties with systems that were not designed to be cycled on and off frequently. However, Chalk Point Units 3 and 4 were intended for peaking service when originally proposed, and as such, the equipment was designed to take frequent start/stop cycles into account. Having had numerous opportunities to inspect the units during the 25- to 30-year period they have been in operation, the operators have reported that the equipment has performed well and does not exhibit to any great degree any of the problems usually associated with the cycling of large steam units. The Dickerson Facility The Dickerson Facility is located approximately 31 miles northwest of Washington, DC and 12 miles south of Frederick, Maryland on a 1,001-acre site less than a mile downstream from the confluence of the Potomac River and Monocacy River in northwestern Montgomery County, Maryland. The Dickerson Facility is comprised of three conventional steam turbine units and three simple-cycle CTs (CT D1, CT H1, and CT H2), with a total net summer generating capacity of 837 MW as listed in Table 3. The Dickerson Facility provides base-load and peaking generation and is capable of using both coal and No. 2 oil for fuel in the steam units, No. 2 oil in Dickerson CT D1 and both gas and No. 2 oil in Dickerson CTs H1 and H2.

The Dickerson Facility was designed utilizing the standard technologies available at the time it was built. Where it has proven economically desirable, or where regulatory changes have required, new technologies have been "backfit" into the Dickerson Facility to improve operations, environmental compliance, and efficiencies. Major examples of this include the installation of wet particulate scrubbers to Dickerson Unit 3 in 1972 and to Dickerson Units 1 and 2 in 1978, and replacement of the pneumatic control systems of Dickerson Units 1, 2 and 3 in 1999. In general, Dickerson Units 1, 2 and 3 have been normally base-loaded, which is common for medium sized coal-fired units located close to a metropolitan area. The Morgantown Facility The Morgantown Facility is located approximately 50 miles south of Washington, DC on a 620-acre site adjacent to the Potomac River near Newburg in Charles County, Maryland. The Morgantown Facility is comprised of two conventional steam turbine units and six simple-cycle CTs, with a total net summer generating capacity of 1,412 MW as listed in Table 4. The Morgantown Facility provides base-load and peaking generation and is capable of utilizing both coal and oil for fuel. Table 4 Unit Characteristics Morgantown Facility Summer Full Load In-Service Capacity Heat Rate Dispatch Unit Fuel Date (MW) (Btu/kWh) Type ---- ---- ---- ---- --------- ---- Units 1 & 2 Coal/No. 6 Oil 1970/1971 1,164 9,050 Base-load CTs 1 & 2 No. 2 Oil 1970/1971 32 14,650 Peaking CTs 3-6 No. 2 Oil 1973 216 12,600 Peaking ----- Total 1,412 In addition, the Morgantown Facility has certain common facilities shared by all units such as river water pumping stations, fuels receiving, storage and handling systems, water treatment systems, warehouses, maintenance shops, a chemistry laboratory, administrative offices, groundwater monitoring wells, and an electrical switchyard. The design and construction of electric utility generating units using pulverized coal or No. 6 residual oil to fire steam boilers has been common for many years, as has the firing of No. 2 distillate oil in CTs. The A-6 Morgantown Facility, although designed and constructed a few years earlier than the Chalk Point Facility, shares many of the same technologies with the Chalk Point Facility. In general, Morgantown Units 1 and 2 have been normally base-loaded, which is common for large, coal-fired units which are generally designed for this type of operation. The Potomac River Facility The Potomac River Facility is located on a 25-acre site along the Potomac River in Alexandria, Virginia. The Potomac River Facility is comprised of five conventional steam turbine units, with a total net summer generating capacity of 482 MW as listed in Table 5. The Potomac River Facility provides base-load and intermediate generation and is capable of utilizing both coal and oil for fuel. Table 5 Unit Characteristics Potomac River Facility Summer Full Load In-Service Capacity Heat Rate Dispatch Unit Fuel Date (MW) (Btu/kWh) Type ---- ---- ---- ---- --------- ---- Units 1 & 2 Coal/No. 2 Oil 1949/1950 176 12,150 Intermediate Units 3-5 Coal/No. 2 Oil 1954/56/57 306 9,870 Base-load --- Total 482 In addition, the Potomac River Facility has certain common facilities shared by all units such as river water pumping stations, fuels receiving, storage and handling systems, water treatment systems, warehouses, maintenance shops, a chemistry laboratory, administrative offices, groundwater monitoring wells, and an electrical switchyard. The design and construction of electric utility generating units using pulverized coal or No. 2 distillate oil to fire steam boilers has been common for many years. The Potomac River Facility was designed utilizing the standard technologies available at the time it was built. Where it has proven economically desirable, or where regulatory changes have required, new technologies have been "backfit" into the Potomac River Facility to improve operations, environmental compliance, and efficiencies. Major examples of this include the installation of new hot-side electrostatic precipitators ("ESPs") in 1979 and replacement of the control systems of Potomac River Units 1, 2, 3, 4 and 5. In general, Potomac River Units 1 and 2 have normally operated to serve intermediate load, which is common for smaller, coal-fired units of this vintage. The Potomac River Units 3, 4 and 5 have been normally base-loaded. Other Facilities The PSC, which is a 145,000-square foot engineering and maintenance facility serving the Mirant Mid-Atlantic Facilities; the Piney Point Pipeline, which supplies No. 6 residual fuel oil to the Chalk Point and Morgantown Facilities; and the Ash Storage Facilities, which receive and store the solid waste materials such as sludges, bottom ash and fly ash produced from the combustion of coal at the Mirant Mid-Atlantic Facilities, are described in more detail in the Supplement. Operation and Maintenance Operation of the Mirant Mid-Atlantic Facilities The Mirant Mid-Atlantic Facilities are operated with operations personnel from Mirant Mid-Atlantic Services, LLC ("Mirant Mid-Atlantic Services"), an indirect wholly-owned subsidiary of Mirant. The Mirant Mid-Atlantic Facilities have no employees of their own. In conjunction with the acquisition of the Mirant Mid-Atlantic A-7 Facilities from Pepco, Mirant Mid-Atlantic Services hired numerous Pepco personnel and currently provides all operations, maintenance and general management personnel to the Mirant Mid-Atlantic Facilities. Mirant Services, LLC ("Mirant Services"), a direct wholly-owned subsidiary of Mirant, provides executive personnel and administrative services to the Mirant Mid-Atlantic Facilities. As part of the purchase of the Mirant Mid-Atlantic Facilities, Mirant Mid-Atlantic Services was assigned the labor contracts for the non-exempt personnel at the Mirant Mid-Atlantic Facilities. Mirant Mid-Atlantic Services retained the services of most of the existing exempt personnel and completed the remaining staffing requirements via internal and external resources. Operating Programs and Procedures Mirant Mid-Atlantic Services adopted Pepco's operating practices and procedures, including its Generation Engineering and Maintenance Services department, and is in the process of coordinating, combining and improving these procedures to maximize the production capabilities of the Mirant Mid-Atlantic Facilities while minimizing the facilities' operating and maintenance costs. We have reviewed the general application of the various operating and maintenance ("O&M") programs and procedures within the Mirant Mid-Atlantic Facilities, including: preventive, corrective and predictive maintenance plans; operating procedures; and maintenance procedures originally put in place by Pepco. We did not review all aspects of these plans and procedures, but verified that all of the usual and necessary plans, procedures and documentation normally required to operate a facility of this type were in place. The PSC is the headquarters of the Mid-Atlantic Facilities and houses the offices of the PSC staff, training areas and a machine shop. The PSC staff provides numerous services to the Mid-Atlantic Facilities and has developed programs and procedures that have been implemented at all of the Mid-Atlantic Facilities. Additional discussion of the PSC is contained in the Supplement. Operating History Operating data for the past several years of operation of the Mirant Mid-Atlantic Facilities was provided by Mirant Mid-Atlantic. The historical averages and corresponding future averages are summarized in Table 6. The projected generation, average annual heat rate, capacity factor, and equivalent availability factor have been estimated by PA Consulting. A more detailed summary of the historical performance results is included in Exhibit A-10 and in the Supplement.

(2) Annual average based on levels of full- and part-load operation as projected by PA Consulting. Projected decreases in annual average heat rates compared to historical heat rates result for some units due to an increase in hours at more efficient, full-load operation projected by PA Consulting. (3) Represents weighted average by generation for annual net heat rate, net capacity and equivalent availability factor. Environmental Assessment Environmental Site Assessment We have reviewed Phase I environmental site assessments ("ESAs") for each of the Mirant Mid-Atlantic Facilities, the Ash Storage Facilities, the PSC, and the pumping station (the "Ryceville Pumping Station") and oil terminal (the "Piney Point Oil Terminal") associated with the Piney Point Pipeline prepared by Pepco's environmental consultant to determine the consistency of their assessment with industry standards. The Phase I ESA reports, dated between December 13 and 16, 1999 consisted of site reconnaissance, interviews, review of facility files, and review of relevant government agency files, including files from the Maryland Department of the Environment ("MDE") and the Virginia Department of Environmental Quality ("VADEQ"). Additionally, we have reviewed comments from Pepco's environmental consultant regarding their follow-up site visits conducted between March 9 and 10, 2000 to the Mirant Mid-Atlantic Facilities, Ash Storage Facilities, the PSC, and the Ryceville Pumping Station. Pepco's environmental consultant stated that "no environmental conditions, other than those noted during the initial site reconnaissance conducted in June 1999, were observed." Additional discussion regarding the findings of Pepco's environmental consultant is included in the Supplement. We have also reviewed an updated report dated December 15, 2000 for the Mirant Mid-Atlantic Facilities prepared by Pepco's environmental consultant. Based on our review, we are of the opinion that the ESAs and updated report for the sites of the Mirant A-9 Mid-Atlantic Facilities were conducted in a manner consistent with industry standards, using comparable industry protocols for similar studies with which we are familiar. The total projected costs for environmental concerns relating to potential site contamination issues are estimated by Mirant Mid-Atlantic to be approximately $12,500,000, which includes a contingency for currently unknown site contamination issues, if any, that may potentially develop in the future. The estimated costs for potential environmental projects have been included as capital expenditures and operation and maintenance expenses in the Projected Operating Results presented later in this Report. Refer to the Supplement for additional information on previously conducted ESAs. Status of Permits and Approvals We have reviewed the key permits and approvals for the Mirant Mid-Atlantic Facilities. A listing of the key permits and approvals is shown in the Supplement. The major permits and approvals required to operate the Mirant Mid-Atlantic Facilities have been obtained and are currently valid or are in the process of being renewed, and we are not aware of any technical circumstances that would prevent the renewal of the major permits or approvals. Regulatory Compliance We have reviewed 1999 and 2000 excess air emissions reports, the Wastewater Discharge Monitoring Reports for 2000 and discussed the compliance status of the Mirant Mid-Atlantic Facilities with personnel working at the Mirant Mid-Atlantic Facilities and those working for Mirant Generation. The Mirant Mid-Atlantic Facilities appear to be in material compliance with the various conditions set forth in the key permits and approvals and consent orders as applicable. We note the following circumstances relative to compliance with permits and approvals that could have an impact on future operations. Additional discussion of certain such circumstances is presented in the Supplement: o The location of the Mirant Mid-Atlantic Facilities in designated ozone non-attainment areas triggered the requirement of Reasonably Available Control Technology ("RACT"). A consent agreement with VADEQ dated July 10, 1998 instituted an emission-averaging plan for oxides of nitrogen ("NO(X)"), where emissions can be over-controlled at certain units to cover the other generating unit requirements. o Title I of the Clean Air Act and subsequent regulations pursuant to the Act, including the United States Environmental Protection Agency ("USEPA") NO(X) State Implementation Plan ("SIP") Call and the Section 126 petitions, established a market based program for NO(X) allowances where units covered by the Act must possess NO(X) allowances to cover their emissions. Maryland has adapted regulations allocating allowances to individual units consistent with the Act beginning in 2000. The Virginia units will be subject to allowance requirements beginning in 2003 because Virginia did not sign the September 1994 Memorandum of Understanding ("MOU") among Eastern Regional Transport Commission states. The future cost of NO(X) allowances will be market dependent and could be lower or higher than the current values for such allowances. The exact number of allowances to be required in the future will depend on the utilization of the units in the future. The number of allowances allocated to the units and future price assumptions are presented in the Supplement. The allowance costs assumed in the Projected Operating Results are presented later in this Report. o The Mirant Mid-Atlantic Facilities are subject to Title IV of the Clean Air Act (Acid Rain Provisions) whereby each unit must possess sulfur dioxide ("SO(2)") allowances to cover its emissions beginning in 2000. The future cost of SO(2) allowances will be market dependent and could be lower or higher than the current values for such allowances. The exact number of allowances to be required in the future will depend on the utilization of the units. The number of allowances allocated to the units and future price assumptions are presented in the Supplement. The allowance costs assumed in the Projected Operating Results are presented later in this Report. o Title IV of the Clean Air Act also imposes specific NO(X) emission limits that must be met (presumptive limits) by all coal units subject to the Act. The Potomac units opted early election into the A-10 program thereby deferring lower emission limits until 2008. The remaining units applied for Alternative Emission Limits ("AELs") to allow more flexibility in operation at emission levels higher than the presumptive limits. The AELs for Morgantown Units 1 and 2 have been approved. Should the AELs for the remaining units not be approved, the retrofit schedule of control equipment may need to be revised in order to comply with more stringent limits than the applied for AELs. o Certain capital expenditures along with associated O&M costs have been identified by Mirant Mid-Atlantic to comply with future environmental requirements; however, Mirant Mid-Atlantic regularly reevaluates cost-effective alternatives to achieve compliance with future environmental regulations. At this point in time, we believe it is reasonable to assume such installations, costs and associated emission rates in the Projected Operating Results with the actual decision to install being made at a later date based on economic evaluations. For the purposes of the Projected Operating Results, based on discussions with Mirant Mid-Atlantic, we have assumed the installation of: (1) low-NO(X) burners at Chalk Point Units 1 and 2 in 2002; (2) selective catalytic reduction ("SCR") at Chalk Point Units 1 and 2 in 2006 and 2008, respectively; (3) separated overfired air ("SOFA") systems at Dickerson Units 1, 2, and 3 in 2002, 2003, and 2003, respectively; (4) SCR and selective non-catalytic reduction ("SNCR") at Morgantown Units 1 and 2 in 2006 and 2008, respectively; and (5) low-NO(X) burners and SOFA systems at Potomac River Units 3, 4, and 5 in 2007, 2007, and 2008, respectively. Specific emission rate assumptions are presented in the Supplement. o The Dickerson Facility is operating under a consent order for opacity. Presently, the Dickerson Facility is undertaking a testing program to verify the feasibility of converting the ESPs to wet ESPs. The capital expenditure for conversion is included in the Projected Operating Results. Should the testing prove to be unsuccessful, a more costly option of adding baghouses is available. o In November 1999, the USEPA issued Notices of Violations ("NOVs") to owners and operators of 32 coal-fired electric generating plants, charging that over many years these plants had been changed or modified in ways that resulted in increased emission of pollutants and that the plants did not obtain new source permits or prevention of significant deterioration permits applicable to new or modified sources. None of the assets included herein have been issued such NOVs. Mirant received a request for information dated January 10, 2001 from the USEPA, pursuant to its authority under the Clean Air Act, requiring Mirant to provide records and information relevant to the operation and maintenance history of the Potomac River, Chalk Point, Dickerson and Morgantown Facilities. Mirant and Mirant Mid-Atlantic are in the process of responding to the request for information. While we cannot predict future USEPA actions, should such notices of violations be issued to any of the assets, the cost to comply could be substantial. o There are a number of potential future regulations that, if promulgated, could increase capital expenditures and O&M costs at the Mirant Mid-Atlantic Facilities. Such potential regulations include mercury control, particulate matter of 2.5 microns or less ("PM(2.5)"), regional haze, regional visibility, water intake structure regulations, potential ratcheting of SO(2) allowances beyond 2009 and Subtitle D regulations pertaining to the disposal of fuel combustion wastes such as ash. The schedule and specific regulations to be promulgated are not presently known; therefore, the impact of such potential regulations has not been incorporated into the Projected Operating Results. MIRANT CALIFORNIA FACILITIES Description of the Facilities The Mirant California Facilities are owned by Mirant California, LLC ("Mirant California") through its direct wholly-owned subsidiaries Mirant Delta, LLC ("Mirant Delta") and Mirant Potrero, LLC ("Mirant Potrero"). Mirant California, Mirant Delta and Mirant Potrero are all indirect wholly-owned subsidiaries of Mirant Generation and are collectively referred to herein as "Mirant California". The Mirant California Facilities consist of the following three separate electric generating facilities: (1) the 680 MW (net) Contra Costa power plant (the "Contra Costa Facility") located approximately 2.5 miles east of Antioch, California; (2) the 1,932 MW (net) Pittsburg power plant (the "Pittsburg Facility") located near Pittsburg, California; and (3) the 350 MW (net) Potrero power plant (the "Potrero Facility") located in the southeast portion of the City and County of San Francisco on the western shore of San Francisco Bay. The Pittsburg and Contra Costa Facilities (the "Delta Facilities") are owned by Mirant Delta. The A-11 Portrero Facility is owned by Mirant Portrero. The Delta Facilities and the Potrero Facility are collectively referred to herein as the "Mirant California Facilities". The Mirant California Facilities were acquired from PG&E in April 16, 1999. Mirant California also maintains an administrative and business support office in Walnut Creek, California. The Contra Costa Facility The Contra Costa Facility consists of two operating units, Contra Costa Units 6 and 7, with a combined capacity of 680 MW. Contra Costa Units 1, 2 and 3 were decommissioned in 1994, but could run, if required, with capital expenditure and permit reinstatement. Contra Costa Units 4 and 5 are operated solely as synchronous condensers and their capability is not included in the stated capacity. The Contra Costa Facility is located on a single 168-acre parcel in the unincorporated area of Contra Costa County along the San Joaquin River Delta. The site is approximately 2.5 miles east of Antioch and 10 miles upstream from the Pittsburg Facility. PG&E retained approximately 20 acres of the parcel containing the switchyard, transmission lines and other transmission related equipment. PG&E also retained a portion of the gas pipeline and the necessary easements to service the gas pipeline and transmission equipment. Contra Costa Units 6 and 7 are each comprised of two steam turbine generators with a combined net generating capacity of 680 MW. The Contra Costa Units 6 and 7 were placed in service in 1964 as natural gas fired and oil fired units, however are no longer capable of firing oil without substantial changes to the boiler burners and permits. Contra Costa Units 4 and 5, which no longer operate as generating units, each operate as synchronous condensers. The units were originally commissioned as generating units but were converted to synchronous condensers in 1993 and 1997, respectively. Contra Costa Unit 4 is rated at 148 MVAR (net) while Contra Costa Unit 5 carries a rating of 104 MVAR (net).

The Suisun Bay is the source of cooling water and the effluent cooling water is returned to the Suisun Bay. PG&E retained approximately 33 acres of the total parcel where the PG&E-owned switchyard exists. The Pittsburg Facility consists of seven units with a total net summer generating capacity of 1,932 MW as listed in Table 8. The Pittsburg Facility boilers were originally designed to burn natural gas as a primary fuel with fuel oil as back up fuel, but are no longer capable of firing oil without changes to the boiler burners and permits.

The Potrero Facility is located on several parcels totaling approximately 36 acres. PG&E has retained approximately nine acres of the total parcel where the PG&E-owned switchyard exists. The Potrero Facility is comprised of a steam boiler plant and three CTs with a total net summer generating capacity of 350 MW as listed in Table 9. Potrero Units 4, 5, and 6 were placed in service in 1976 using No. 2 distillate fuel oil as a primary fuel.

The operating and maintenance programs, including: (1) operating procedures and programs; (2) preventive, predictive and corrective maintenance programs and procedures; (3) work management process; (4) work order and high energy piping inspection procedures; (5) reporting and documentation requirements; and (6) plant performance monitoring programs were previously reviewed at the Mirant California Facilities. During the site visits, the material condition of the plants was observed and discussions were held with plant operations and maintenance management. The operating programs at the Mirant California Facilities include the management, engineering, maintenance, financial, administrative and support groups necessary to operate and maintain the station in accordance with accepted industry operating practices. During discussions at the plants, the plant managers reported that there has been minimal personnel turnover in plant operations and maintenance. The plant managers at the Mirant California Facilities plan to increase productivity and realize savings through a number of operational changes, including broadening job definitions for operations and increased participation in day-to-day decision making at all levels of the organization. The Mirant California Facilities have instituted program initiatives that, if successful, will improve station operating and maintenance practices and performance. Included are performance management programs for A-13 station personnel; a maintenance planning process that will improve both preventive and corrective maintenance performance; and a team-based concept that will provide operating and maintenance personnel additional responsibility and authority to operate and maintain the plants while maintaining the necessary management guidance and oversight. These programs are geared to reducing operating and maintenance costs and improving station performance indicators. In addition, financial incentives are being provided, beginning in 2001, for employee generated cost savings and other improvements in plant operation and administrative processes. Operating Programs and Procedures PG&E is contracted under an operating and maintenance agreement to operate the Mirant California Facilities for two years under the direction of Mirant California management. At the end of the two-year period ending April 16, 2001, most PG&E employees are expected to be hired by Mirant California. The Mirant California maintenance department utilizes Maximo, which is the maintenance management system that has been selected by Mirant Generation for use in all of its generating plants. Corrective and preventive maintenance activities are documented and recorded using work orders. Maximo is used to manage the maintenance activities. A predictive and preventive maintenance program is employed at the plants. Major maintenance is presently scheduled on a three-year cycle for the boilers and a 6-year interval for the steam turbine-generators. The overhaul duration is typically six to eight weeks, depending on the scope of the work to be performed. Virtually all of the Mirant California Facilities' major maintenance for the next few years will be performed during outages dictated by the installation of SCR systems or low-NO(X) burners, both to reduce NO(X) emissions. Major outages are scheduled for Contra Costa Units 6 and 7 in 2000-2001 to install systems to reduce stack emissions. Low-NO(X) burners were recently installed on Contra Costa Unit 6. Contra Costa Unit 7 is scheduled for installation of a SCR system from March to June of 2001 with Contra Costa Unit 6 SCR installation scheduled for 2003. Major outages are scheduled for Pittsburg Units 1 through 7 within the next three years to install systems to reduce stack emissions or correct equipment concerns that are affecting reliability. Pittsburg Units 1 through 4 will retube the condensers and perform boiler repair work in 2001. Pittsburg Units 5 and 6 just completed installation of low-NO(X) burners and are scheduled to install SCRs in 2001-2002. Pittsburg Unit 7 is scheduled to install an SCR in 2003. The SCR outages will be between 14 and 20 weeks long. Potrero Unit 3 will have two major outages in the next four years, 2001 to retube the condenser and make boiler repairs as necessary and 2004 to install an SCR. The scheduled duration of these outages is 10 and 20 weeks respectively. Operating History Operating data for the past several years of operation of the Mirant California Facilities was provided by Mirant California. The historical averages and corresponding future averages are summarized in Table 10. The projected generation, average annual heat rate, capacity factor, and equivalent availability factor have been estimated by PA Consulting. A more detailed summary of the historical performance results is included in Exhibit A-10 and in the Supplement.

Environmental Assessment Environmental Site Assessment In connection with the sale of the Mirant California Facilities, PG&E agreed to undertake any remediation (including during decommissioning) that relates to any pre-closing environmental condition or transmission environmental condition required by any governmental authority with jurisdiction over the Mirant California Facilities. If Mirant Delta or Mirant Potrero chooses to develop a plant other than a fossil-fueled power plant or a substantially similar industrial purpose, which development would make the costs of environmental remediation materially higher, PG&E's costs of remediation will be capped at the costs which would have been incurred if there had been no change in use. Long-term remediation activities and future remediation of residual contamination under structures on the plant sites are PG&E's responsibility. PG&E is not, however, responsible for other remediation work unless changes in environmental laws or in the environmental cleanup standards of a governmental authority require additional remediation. Due to the environmental indemnity in the Purchase and Sale Agreements which obligates PG&E to indemnify Mirant Potrero and Mirant Delta for pre-existing environmental conditions at the sites of the Mirant California Facilities, no funds for environmental remediation are included in the Projected Operating Results. In 1999, we reviewed Phase I and II ESA reports prepared in 1997 and 1998, respectively, for the Mirant California Facilities regarding investigations of known or potential site contamination issues in connection with the sites of the Mirant California Facilities. Because no updated ESAs of previous or recent environmental investigations regarding the potential for site contamination issues at the sites of the Mirant California Facilities have been provided for our review, we can offer no opinion with respect to potential site contamination issues at the sites of the Mirant California Facilities, if any, or potential future remediation costs should contamination be found. While we have not independently investigated site conditions, Mirant California reported that, to its knowledge, the conditions at A-15 the sites of the Mirant California Facilities are materially similar to those presented in the 1997 and 1998 ESAs. Refer to the Supplement for additional information on previously conducted ESAs. Status of Permits and Approvals We have reviewed the key permits and approvals for the Mirant California Facilities. A listing of the key permits and approvals is shown in the Supplement. The major permits and approvals required to operate the Mirant California Facilities have been obtained and are currently valid or are in the process of being renewed, and we are not aware of any technical circumstances that would prevent the renewal of the major permits or approvals. Regulatory Compliance We have reviewed 1999 and 2000 excess air emissions reports, the Wastewater Discharge Monitoring Reports for 2000 and discussed the compliance status of the Mirant California Facilities with Mirant California and Mirant Generation personnel. The Mirant California Facilities appear to be in material compliance with the various conditions set forth in the key permits and approvals. We note the following circumstances relative to compliance with permits and approvals that could have an impact on future operations. Additional discussion of certain such circumstances is presented in the Supplement: o During 1995, the Bay Area Air Quality Management District ("BAAQMD") amended Rule 9-11, which regulates the control of NO(X) and CO emissions from Utility Electric Power Generating Boilers. This Rule establishes specific "system-wide" emission limitations to be achieved by boilers greater than or equal to 250 MMBtu/hr. For purposes of this Report, "system-wide" emission limitations refers to all power generation owned and/or operated by Mirant California. This Rule will necessitate the installation of specific control equipment on certain of the existing units. Refer to the Supplement for additional information. o Certain capital expenditures along with associated O&M expenses have been identified by Mirant California to comply with future environmental requirements of Rule 9-11. At this point in time, we believe it is reasonable to assume such installations, costs and associated emission rates in the Projected Operating Results. For the purposes of the Projected Operating Results, based on discussions with Mirant California, we have assumed the installation of: (1) low-NO(X) burners on Contra Costa Unit 6 by February 2001 and a SCR System by May 2003; (2) SCR installation on Contra Costa Unit 7 by June 2001; (3) SCR installation on Pittsburg Unit 5 by July 2002; (4) SCR installation on Pittsburg Unit 6 by April 2002; (5) SCR installation on Pittsburg Unit 7 by May 2003; and (6) SCR installation on Potrero Unit 3 by May 2004. Specific emission rate assumptions used in the Projected Operating Results are given in the Supplement. o Pittsburg Units 1 through 4 will require SCR retrofits should they be kept operating so that compliance with Rule 9-11 can be achieved in the 2002-2004 timeframe. Capital expenditures and associated operating and maintenance expenses have been included in the Projected Operating Results. o The Mirant California Facilities are subject to Title IV of the Clean Air Act (Acid Rain Provisions) whereby each unit must possess SO(2) allowances to cover its emissions beginning in 2000. The future cost of SO(2) allowances will be market dependent and could be lower or higher than the current values for such allowances. The exact number of allowances to be required in the future will depend on the utilization of the units. Specific emission rate assumptions and the number of allowances allocated to each facility are presented in the Supplement. The allowance costs assumed in the Projected Operating Results are presented later in this Report. o There are a number of potential future regulations that, if promulgated, could increase capital expenditures and O&M costs at the Mirant California Facilities. Such potential regulations include mercury control, PM(2.5), regional haze, regional visibility, water intake structure regulations, potential ratcheting of SO(2) allowances beyond 2009 and Subtitle D regulations pertaining to the disposal of fuel combustion wastes. The schedule and specific regulations to be promulgated are not presently known; therefore, the impact of such potential regulations has not been incorporated into the Projected Operating Results. In addition, due to the A-16 fact that the Mirant California Facilities operate primarily on natural gas, the impact of these potential regulations is not likely to be significant. o The cooling water intakes for the Pittsburg and Contra Costa Facilities are located in a nursery area for striped bass, which is considered a valued fishery resource. The Pittsburg and Contra Costa Facilities are operating under a Resource Management Program required under the National Pollutant Discharge Elimination System ("NPDES") Permits that imposes certain restrictions on the thermal water outfall during the spawning period, considered to be between May and July of each year. The renewal of the NPDES Permit and the need to obtain a federal Take Permit for impacting endangered species will likely require additional capital expenditures and O&M expenses at the Mirant California Facilities. For the purposes of the Projected Operating Results, based on discussions with Mirant California, we have assumed the installation of Gunderbooms at the Contra Costa and Pittsburg Facilities. Gunderbooms are an aquatic filter barrier system that proposes to lessen the plant's cooling water system impact on the fish species by excluding them from entrainment and impingement as the full cooling water flow is drawn through a fabric barrier at low velocity. The actual decision to install the Gunderbooms will be made at a later date based on the outcome of the agency negotiations regarding the federal Take Permit. Refer to the Supplement for additional information. MIRANT NEW YORK FACILITIES Description of the Facilities The Mirant New York Facilities consist of generating units located at eight separate facility sites in New York. The thermal generating units consist of the Bowline power plant (the "Bowline Facility") owned by Mirant Bowline, LLC ("Mirant Bowline"); the Lovett power plant (the "Lovett Facility") owned by Mirant Lovett, LLC ("Mirant Lovett"); and the Hillburn power plant (the "Hillburn Facility"), all located in Rockland County, New York; and the Shoemaker power plant (the "Shoemaker Facility") located in Orange County, New York. The Hillburn and Shoemaker Facilities are referred to collectively as the "NY CT Facilities". The hydroelectric generating units (collectively, the "Hydroelectric Facilities") consist of the Mongaup power plant (the "Mongaup Facility"); the Swinging Bridge power plant (the "Swinging Bridge Facility"); the Rio power plant (the "Rio Facility"); and an operational interest in the Grahamsville power plant (the "Grahamsville Facility"). The NY CT Facilities and the Hydroelectric Facilities are owned by Mirant NY-Gen, LLC ("Mirant NY-Gen"). Each of Mirant Bowline, Mirant Lovett, and Mirant NY-Gen are indirect wholly-owned subsidiaries of Mirant Generation and are collectively referred to as "Mirant New York". All of these Facilities were acquired from Orange and Rockland Utilities, Inc. ("ORU") on July 1, 1999. There is an administrative and engineering office for the Mirant New York Facilities in Suffern, New York. The Bowline Facility The Bowline Facility is located approximately 35 miles north of New York City on a site of approximately 160 acres adjacent to the Hudson River in West Haverstraw, New York. In addition to the existing Bowline Facility property, an additional 98 acres of adjacent property is owned by Mirant Bowline, of which approximately 75 acres is in an upland area, and 23 acres are underwater acres in the Hudson River. The Bowline Facility is comprised of two conventional steam turbine units with a total net summer generating capacity of 1,212 MW as listed in Table 11. The Bowline Facility is the largest of the Mirant New York Facilities. It provides peaking and intermediate generation and is capable of utilizing both No. 6 fuel oil and natural gas. A-17 Table 11 Unit Characteristics Bowline Facility Summer Full Load In-Service Capacity Heat Rate Dispatch Unit Fuel Date (MW) (Btu/kWh) Type ---- ---- ---- ---- --------- ---- Units 1 & 2 Gas/No. 6 Oil 1972/74 1,212 9,843 Intermediate In addition, the Bowline Facility has certain common facilities shared by both units such as river water pumping stations, fuels receiving, storage and handling systems, water treatment systems, warehouses, maintenance shops, a chemistry laboratory, administrative offices and an electrical switchyard. The design and construction of electric utility generating units using natural gas or No. 6 fuel oil to fire steam boilers has been common for many years. The Bowline Facility was designed utilizing the standard technologies available at the time it was built. Where it has proven economically desirable, or where regulatory changes have been required, new technologies have been "backfit" into the Bowline Facility to improve operations, environmental compliance, and efficiencies. Examples of this include control system replacements, burner and combustion equipment upgrades, and the replacement of turbine components with improved designs. In general, Bowline Units 1 and 2 have been operated as intermediate units, although in recent years, due to equipment conditions, Bowline Unit 2 has been utilized more as a peaking unit. Planning is currently in progress for a third unit at the Bowline Facility. This unit would be a gas-fired combined cycle unit with a capacity of approximately 750 MW and would utilize natural gas from a new pipeline that is currently being developed. We have not included any of the costs or revenues associated with this planned new unit in the Projected Operating Results. The Lovett Facility The Lovett Facility is located approximately 40 miles north of New York City on a site of approximately 60 acres on the west bank of the Hudson River in Tompkins Cove, New York. The Lovett Facility is comprised of three conventional steam turbine units with a total net summer generating capacity of 432 MW, as listed in Table 12. The Lovett Facility provides both peaking and base-load generation and is capable of utilizing coal, No. 6 fuel oil and natural gas. Table 12 Unit Characteristics Lovett Facility Summer Full Load In-Service Capacity Heat Rate Dispatch Unit Fuel Date (MW) (Btu/kWh) Type ---- ---- ---- ---- --------- ---- Unit 3 Gas/No. 6 Oil 1955 67 11,000 Peaking Unit 4 Coal/Gas/No. 6 Oil 1966 172 10,774 Base-load Unit 5 Coal/Gas/No. 6 Oil 1968 193 10,833 Base-load --- Total 432 In addition, the Lovett Facility has certain common facilities shared by the three units such as river water pumping stations, fuels receiving, storage and handling systems, water treatment systems, warehouses, maintenance shops, a chemistry laboratory, administrative offices and an electrical switchyard. Lovett Units 1 and 2 were retired in 1995. A-18 The design and construction of electric utility generating units using coal, natural gas or No. 6 fuel oil to fire steam boilers has been common for many years. The Lovett Facility was designed utilizing the standard technologies available at the time it was built. Where it has proven economically desirable, or where regulatory changes were required, new technologies have been "backfit" into the Lovett Facility to improve operations, environmental compliance, and efficiencies. Examples of this include control system replacements, burner and combustion equipment upgrades, installation of new ESPs on Lovett Units 4 and 5, conversion of Lovett Unit 4 to balanced draft operation and the replacement of turbine components with improved designs. In general, Lovett Units 4 and 5 have normally been base-loaded, which is common for medium sized coal-fired units which have generally been designed for this type of operation. Lovett Unit 3, which is limited to firing either No. 6 fuel oil or natural gas, is normally operated as a peaking unit. The NY CT Facilities The Hillburn Facility is located in the Village of Hillburn, Town of Ramapo, New York, and the Shoemaker Facility is located in the Towns of Wawayanda and Wallkill, City of Middletown, New York. Each of the NY CT Facilities is comprised of a single simple cycle CT unit with a total net summer generating capacity of 76 MW in the aggregate, as listed in Table 13. The NY CT Facilities are generally operated in peaking service. Table 13 Unit Characteristics NY CT Facilities Summer Full Load In-Service Capacity Heat Rate Dispatch Unit Fuel Date (MW) (Btu/kWh) Type ---- ---- ---- ---- --------- ---- Hillburn Gas/Kerosene 1971 36 15,000 Peaking Shoemaker Gas/Kerosene 1971 40 15,000 Peaking -- Total 76 The Hydroelectric Facilities The Hydroelectric Facilities have a total net summer generating capacity of 44 MW in the aggregate, as listed in Table 14. The Mongaup Facility, Swinging Bridge Facility and Rio Facility are "Mongaup River Projects" under federal law and are licensed by the Federal Energy Regulatory Commission ("FERC") as projects number 10481, 10482 and 9690, respectively. The licenses are not due to expire until 2022. The Grahamsville Facility was constructed and is operated pursuant to an agreement with New York City which allows for the Grahamsville Facility to be operated at the end of the East Delaware Tunnel for a period of 50 years. Mirant NY-Gen is currently negotiating an extension of this agreement, which expires in 2006. For the purpose of the Projected Operating Results, we have assumed this agreement will be renewed at the same terms and conditions. With the exception of the Grahamsville Facility that is base-loaded, the Hydroelectric Facilities are generally operated in peaking service, depending on water availability.

While several management personnel, including the plant managers, were brought in from affiliates of Mirant New York, the majority of the operating staffs for the facilities were hired from ORU at the time the facilities were purchased. The Suffern office provides administrative support to the Facilities in the areas of accounting and payroll, human resources, marketing, environmental management, management of the Hydroelectric and NY CT Facilities, and engineering. In June of 2000, a new collective bargaining agreement was entered into with the International Brotherhood of Electrical Workers Union that represents the hourly personnel at the Facilities. This agreement provides Mirant New York with more flexibility in assigning work to different classifications of workers, and provides that competency testing be utilized in addition to seniority when employees are being considered for advancement. Operating Programs and Procedures The Maximo maintenance management system has been implemented at all of the Mirant New York Facilities. All maintenance work including corrective, preventive and predictive maintenance is scheduled and tracked utilizing this system. Working with a consultant, Mirant New York intends to optimize the use of the Maximo system over the next two years. This optimization may include the combining of certain resources between the Bowline and Lovett facilities, and will address both short-term and long-term maintenance needs. Currently, many of the former owners' maintenance and operations practices are still in place, and Mirant New York is continuing to work towards reducing the backlog of maintenance work that existed when the facilities were purchased. Changes implemented by Mirant New York to date include an increased emphasis on inspections and more in depth root cause analysis to identify problems rather than simply performing superficial repairs. In operations, increased emphasis has been placed on environmental compliance, especially for opacity, and additional environmental training has been scheduled for the operators. Operating History Operating data for the past several years of operation of the Mirant New York Facilities was provided by Mirant New York. The historical averages and corresponding future averages are summarized in Table 15. The projected generation, average annual heat rate, capacity factor, and equivalent availability factor have been estimated by PA Consulting. A more detailed summary of the historical performance results is included in Exhibit A-10 and in the Supplement.

Environmental Assessment Environmental Site Assessment Mirant New York has purchased liability insurance for potential pre-existing, but unknown, environmental contamination at the Mirant New York Facilities, with a 10-year term and $15 million in coverage for the Mirant New York Facilities other than the Hydroelectric Facilities. In 1999, we reviewed Phase I and II ESA reports prepared for the Mirant New York Facilities regarding investigations of known or potential site contamination issues and environmental liability issues for Bowline and Lovett Facilities, the Hydroelectric Facilities and NY CT Facilities. These assessments were prepared during August 1998, October 1998, and June 1999. Because no updated ESAs of previous or recent environmental investigations regarding the potential for site contamination issues at the sites of the Mirant New York Facilities have been provided for our review, we can offer no opinion with respect to potential site contamination issues at the sites of A-21 the Mirant New York Facilities, if any, or potential future remediation costs should contamination be found. While we have not independently investigated site conditions, Mirant New York reported to us that, to its knowledge, the conditions at the sites of the Mirant New York Facilities are materially similar to those presented in the 1998 and 1999 ESAs. For the purposes of the Projected Operating Results, Mirant New York has allocated $1,000,000 for the contingency environmental response work at the Mirant New York Facilities. Refer to the Supplement for additional information on previously conducted site assessments. Status of Permits and Approvals We have reviewed the key permits and approvals for the Mirant New York Facilities. A listing of the key permits and approvals is shown in the Supplement. The major permits and approvals required to operate the Mirant New York Facilities have been obtained and are currently valid or are in the process of being renewed, and we are not aware of any technical circumstances that would prevent the renewal of the major permits or approvals. Regulatory Compliance We have reviewed 1999 and 2000 excess air emissions reports, the Wastewater Discharge Monitoring Reports for 2000 and discussed the compliance status of the Mirant New York Facilities with Mirant New York and Mirant Generation personnel. The Mirant New York Facilities appear to be in material compliance with the various conditions set forth in the key permits and approvals and consent orders as applicable. We note the following circumstances relative to compliance with permits and approvals that could have an impact on future operations. Additional discussion of certain such circumstances is presented in the Supplement. o The location of the Mirant New York Facilities in designated ozone non-attainment areas triggered the requirement of RACT. The Mirant New York Facilities use low-NO(X) burners and combustion modifications in addition to a NO(X) averaging plan consistent with applicable regulations to comply with RACT limits. o Title I of the Clean Air Act and subsequent regulations pursuant to the Act, including the USEPA NO(X) SIP Call and Section 126 Petitions, established a market-based program for NO(X) allowances where units covered by the Act must possess NO(X) allowances to cover their emissions. New York promulgated regulations allocating allowances to the Mirant New York Facilities. The future cost of NO(X) allowances will be market dependent and could be lower or higher than the current values for such allowances. The exact number of allowances to be required in the future will depend on the utilization of the units in the future. Specific emission rate assumptions and the number of allowances allocated to each facility are presented in the Supplement. The allowance costs assumed in the Projected Operating Results are presented later in this Report. o The Mirant New York Facilities are subject to Title IV of the Clean Air Act (Acid Rain Provisions) whereby each unit must possess SO(2) allowances to cover its emissions beginning in 2000. The future cost of SO(2) allowances will be market dependent and could be lower or higher than the current values for such allowances. The exact number of allowances to be required in the future will depend on the utilization of the units. Specific emission rate assumptions and the number of allowances allocated to each facility are presented in the Supplement. The allowance costs assumed in the Projected Operating Results are presented later in this Report. o Title IV of the Clean Air Act also imposes specific NO(X) emission limits that must be met (presumptive limits) by all coal units subject to the Act. The existing New York NO(X) limits for the coal-fired Lovett Units 4 and 5 are more stringent than the Title IV Acid Rain NO(X) regulations. o For the purposes of the Projected Operating Results, based on discussions with Mirant New York, we have assumed that Mirant New York would not implement any further retrofits of the Lovett and Bowline Facilities with NO(X) and SO(2) reduction technologies. Mirant New York plans to purchase SO(2) and NO(X) allowances from the open market should the plants exceed their respective allowance allocations. A-22 o The Bowline and Lovett Facilities are operating under a New York State Department of Environmental Conservation Consent Order/Decree for compliance with New York State's opacity standard. The consent order was issued to ORU on July 28, 1998 and establishes a stipulated penalty schedule for future non-compliance episodes. During the fourth quarter 1999 to the third quarter 2000 total compliance penalties assessed to the Bowline and Lovett Facilities were $10,000 and $41,400, respectively. It is expected that the consent order will be incorporated into the Title V Permits once they are issued. o The Bowline Facility is one of a number of plants operating with once through cooling water to the Hudson River. Under the terms of the Hudson River Settlement Agreement ("HRSA"), the plant has the potential to be restricted in its operation during May 15 to July 31. In addition to this requirement, a credit-banking system was established to allow units to operate if credits are available. Mirant New York has reported that sufficient credits have been available in the past to operate the Bowline Facility at desired levels without curtailment. For additional description of the HRSA, refer to the Supplement. o In November 1999, the USEPA issued NOVs to owners and operators of 32 coal-fired electric generating plants, charging that over many years these plants had been changed or modified in ways that resulted in increased emission of pollutants and that the plants did not obtain new source permits or prevention of significant deterioration permits applicable to new or modified sources. None of the Mirant New York Facilities have been issued such NOVs. In October 1999, Mirant's parent corporation received an information request from the State of New York concerning air quality control implications of various repairs and maintenance at the Lovett Facility. While we cannot predict future USEPA and State of New York actions, should such NOVs be issued to any of the assets, the cost to comply could be substantial. o The Lovett Facility received an NOV May 25, 2000 from the New York Department of Environmental Conservation ("DEC") alleging violations of the New Source Review rules in that over the years the plant has been modified or changed in ways that resulted in increased emission of pollutants without proper authorization under the New Source Review rules. The NOV was issued to the previous owner, ORU. To date, Mirant New York has not received an NOV. Should the NOV issued result in any required plant modifications, the cost to comply could be substantial. o There are a number of potential future regulations that, if promulgated, could increase capital expenditures and O&M cost at the Mirant New York Facilities. Such potential regulations include mercury control, PM(2.5), regional haze, regional visibility, water intake structure regulations, potential ratcheting of SO(2) allowances beyond 2009, potential ratcheting of SO(2) and NO(X) emissions by New York, and Subtitle D regulations pertaining to the disposal of fuel combustion wastes. The schedule and specific regulations to be promulgated are not presently known; therefore, the impact of such potential regulations has not been incorporated into the Projected Operating Results. MIRANT NEW ENGLAND FACILITIES Description of the Facilities The Mirant New England Facilities consist of generating units located at four separate facility sites in New England. The thermal generating units consist of the Canal power plant (the "Canal Facility") located in Sandwich, Massachusetts; the Kendall power plant (the "Kendall Facility") located in Cambridge, Massachusetts; the power plant facilities located in two locations on Martha's Vineyard (the "Martha's Vineyard Facility"); and an ownership interest in the Wyman power plant located on Cousins Island in Yarmouth, Maine (the "Wyman Facility"). The Martha's Vineyard and Wyman Facilities have not been reviewed, nor have their revenues or expenses been included in the Projected Operating Results. Mirant Generation estimates that these units would have an immaterial impact on the overall revenue of the Mirant Generation Facilities. The Kendall Facility is owned by Mirant Kendall, LLC ("Mirant Kendall"), which is an indirect wholly-owned subsidiary of Mirant Generation. The Canal Facility is owned by Mirant Canal LLC ("Mirant Canal"), which is also an indirect wholly-owned subsidiary of Mirant Generation. Mirant Kendall and Mirant Canal are collectively referred to herein as "Mirant New England". All of the Mirant New England Facilities were acquired from subsidiaries of Commonwealth Energy System ("Commonwealth") and Eastern Utilities Associates ("EUA") in December 1998. There is an administrative and engineering office for the Mirant New England Facilities in Rockland, Massachusetts. Revenues from the Canal Facility Unit 1 are derived from A-23 Power Purchase Agreements with Cambridge Electric Light Company and Commonwealth Electric Company (jointly), Boston Edison Company, Montaup Electric Company, and an affiliate of Mirant Generation that expire on October 10, 2002. The Canal Facility The Canal Facility is located on the south side of Cape Cod Canal in Sandwich, Massachusetts. The plant is approximately one mile from the east end of the canal entrance to Cape Cod Bay. The Canal Facility is located on an approximately 132-acre site. The Canal Facility is comprised of two steam turbine generators with a total net summer generating capacity of 1,112 MW as listed in Table 16. The Canal Facility provides intermediate generation and is capable of utilizing No. 6 oil or natural gas. Table 16 Unit Characteristics Canal Facility Summer Full Load In-Service Capacity Heat Rate Dispatch Unit Fuel Date (MW) (Btu/kWh) Type ---- ---- ---- ---- --------- ---- Unit 1 No. 6 Oil 1968 559 9,287 Intermediate Unit 2 Gas/No. 6 Oil 1976 553 9,862 Intermediate ----- Total 1,112 The Kendall Facility The Kendall Facility is located on approximately six acres of land along the Charles River in Cambridge, Massachusetts. The plant is located at the junction of the Broad Canal and the Charles River. The Broad Canal is the source of cooling water and the effluent cooling water is returned to the Charles River. The Kendall Facility consists of three condensing steam turbines and two aeroderivative single-shaft gas turbines with a total net summer generating capacity of 97 MW, as listed in Table 17. The Kendall Facility delivers steam to a subsidiary of NSTAR for distribution to industrial users and a major health care facility located on the Boston side of the Charles River. The Kendall Facility also has two auxiliary boilers to supply supplemental heating steam for off-site distribution during periods of high demand. These boilers are owned by NSTAR and operated by Mirant Kendall. The present configuration of the Kendall Facility has been developed over the last 52 years. In 1949, the boilers for Kendall Units 1 and 2 and the steam turbine for Kendall Unit 1 were installed. In 1951, the steam turbine for Kendall Unit 2 was added, increasing the total output. In 1954, the boiler for Kendall Unit 3 was added and Kendall Unit 3 was commissioned in 1958. CTs 1 and 2 were installed and commissioned in 1970 and 1972, respectively. To increase reliability and support the increasing steam loads, two package boilers were installed in the 1970-1971 time frame. Natural gas is delivered to the Kendall Facility through an underground piping system. In addition to providing electric energy and industrial steam to the Cambridge and Boston distribution systems, the Kendall Facility supports the Cambridge electrical distribution by providing voltage support when requested by the New England Independent System Operator ("ISO-NE") during demand periods. Mirant Kendall is installing a CT, heat recovery steam generator cogeneration plant that will increase both the electric power and steam generation capabilities of the Kendall Facility. The design of the cogeneration plant has not been reviewed, nor has its potential benefit been considered in the preparation of the Projected Operating Results. The facilities also include three power boilers, a control room, fuel oil storage tanks, and a fuel oil transfer house.

The Martha's Vineyard Facility consists of five 2.75 MW internal combustion, diesel generators located on the island of Martha's Vineyard. Two of the diesel generators were installed at the Oak Bluffs plant in 1969 and a third was installed in 1972. In 1975, the West Tisbury plant was placed in service with two diesel generators. Mirant Canal also owns an approximately 1.4 percent ownership interest, or 8.8 MW, in Wyman Unit 4. Wyman Unit 4 is a 618 MW unit firing No. 6 oil located on Cousins Island in Yarmouth, Maine. Wyman Unit 4 was placed in operation in 1978. We have not reviewed the Martha's Vineyard or Wyman Facilities, nor have we included any revenues or expenses from these facilities in the Projected Operating Results. Operation and Maintenance Operation of the Mirant New England Facilities We have visited both the Canal and Kendall Facilities. The operating and maintenance programs, including operating procedures and programs; preventive, predictive and corrective maintenance programs and procedures; planning and scheduling requirements and procedures; and reporting and documentation requirements were reviewed at both the Canal and Kendall Facilities. During the site visits, the material condition of the plants was observed, and discussions were held with plant operating and maintenance management. The operating programs at both the Canal and Kendall Facilities include the management, engineering, maintenance, financial, administrative and support groups necessary to operate and maintain the station in accordance with accepted industry operating practices. During discussions at the plant, both the Canal and Kendall Facility plant managers reported that there is minimal personnel turnover in the plant operating and maintenance staff. The plant managers at both the Canal and Kendall Facilities have indicated that planned and proposed changes in the operating organization and increased operator participation in the day-to-day decision making will reduce operating costs in the near term while maintaining the quality of the operations. Both the Canal and Kendall Facilities have instituted program initiatives that, if successful, will improve station O&M practices and performance. Included are performance management programs for station personnel; a maintenance planning process that will improve both preventive and corrective maintenance performance; and a team-based concept that will provide operating and maintenance personnel additional responsibility and authority to operate and maintain the plants while maintaining the necessary management guidance and oversight. These programs are geared to reducing operating and maintenance costs and improving station performance indicators. A-25 Operating Programs and Procedures The Mirant New England maintenance departments utilize the Maximo maintenance management system. The Canal Facility also utilizes a Plant Information ("PI") System. The PI system will display and trend most of the important power plant variable parameters. Canal Facility managers trend parameters that are indicative of degraded equipment and systems. At the Kendall Facility, Maximo is being used for inventory control. The Kendall Facility plant managers reported that additional Maximo functions are being activated. Major maintenance of the Canal Facility is presently scheduled on a two-year cycle for the steam generators and a six-year cycle for the steam turbines. Overhaul duration is typically six to eight weeks, depending on the scope of the work to be performed. If there is no major overhaul scheduled, a two- to six-week outage is performed on the steam generator and required auxiliaries. A major turbine overhaul is scheduled for Canal Unit 1 in 2001 to improve the turbine efficiency. Major maintenance at the Kendall Facility is planned to assure that the export steam supply is 100 percent reliable. The major equipment at the Kendall Facility has demonstrated good reliability. Boilers are alkaline cleaned on approximately a 10-year cycle. The Kendall Unit 3 boiler was cleaned in 1999. The steam turbines have a major inspection/overhaul every 8 to 10 years. The major overhaul for the Kendall Unit 2 turbine was delayed in 2000 and is scheduled for the fall of 2001. During this overhaul, improvements in turbine internals will improve overall efficiency. Overhaul schedules are dependent on total hours of operation and the number of start cycles. Operating History Operating data for the past five years of operation of the Mirant New England Facilities was provided by Mirant New England. The historical averages and corresponding future averages are summarized in Table 18. The projected generation, average annual heat rate, capacity factor, and equivalent availability factor have been estimated by PA Consulting. A more detailed summary of the historical performance results is included in Exhibit A-10 and in the Supplement.

Environmental Assessment Environmental Site Assessments Canal Electric Company and Cambridge Electric Light Company retained responsibility for environmental response work under the Massachusetts Contingency Plan for certain environmental conditions at the Canal and Kendall Facilities, which have been identified in the relevant Asset Sale Agreements. The environmental conditions at the Canal and Kendall Facilities that are being addressed under the Massachusetts Contingency Plan are identified in the Canal Electric Asset Sale Agreement and were reported in the Phase I and Phase II environmental studies by an environmental consultant engaged by the Commonwealth subsidiaries undertaken in connection with the divestiture process. In connection with the sale of the Mirant New England Facilities, Commonwealth and EUA have provided a $15 million pollution liability insurance policy to Mirant Canal and Mirant Kendall which is intended to mitigate the risk of any unknown contamination at the Canal Facility or the Kendall Facility that could trigger a legal requirement to perform an environmental cleanup or could give rise to third party claims within ten years after the closing. In 1999, we reviewed the various Phase I and II ESA reports regarding environmental investigations prepared for the Canal and Kendall Facilities, as well as a risk characterization report for the Kendall Facility, which was originally prepared in 1997 and updated in 1998 by a different environmental consultant. The Phase I and II environmental consultant encountered observable and historical evidence of potential site contamination that resulted in the environmental consultant conducting subsurface environmental investigations that consisted of soil and groundwater sampling during various phases at the Canal and Kendall Facilities. The environmental consultant conducting subsurface environmental investigations at the Canal and Kendall Facilities found historical releases of oil and hazardous materials had occurred at both facilities. Mirant Canal's potential future costs associated with the A-27 release at its facility are estimated to be less than $100,000 per year and have been included in the Projected Operating Results. The releases at the Kendall Facility are being remediated by Commonwealth. Because no updated ESAs of previous or recent environmental investigations regarding the potential for site contamination issues at the sites of the Mirant New England Facilities have been provided for our review, we can offer no opinion with respect to potential site contamination issues at the sites of the Mirant New England Facilities, if any, or potential future remediation costs should contamination be found. While we have not independently investigated site conditions, Mirant Canal and Mirant Kendall reported that, to their knowledge, the conditions at the site of the Mirant New England Facilities are materially similar to those presented in the 1997 and 1998 ESAs. Refer to the Supplement for additional information on previously conducted ESAs. Status of Permits and Approvals We have reviewed the key permits and approvals for the Mirant New England Facilities. A listing of the key permits and approvals is shown in the Supplement. The major permits and approvals required to operate the Mirant New England Facilities have been obtained and are currently valid or are in the process of being renewed, and we are not aware of any technical circumstances that would prevent the renewal of the major permits or approvals. Regulatory Compliance We have reviewed 1999 and 2000 excess air emissions reports, the Wastewater Discharge Monitoring Reports for 2000 and discussed the compliance status of the Mirant New England Facilities with Mirant New England and Mirant Generation personnel. The New England Facilities appear to be in material compliance with the various conditions set forth in the key permits and approvals. We note the following circumstances relative to compliance with permits and approvals that could have an impact on future operations. Additional discussion on certain of such circumstances is presented in the Supplement: o The location of the Mirant New England Facilities in designated ozone non-attainment areas triggered the requirement of RACT. The Mirant New England Facilities are operating with emission levels consistent with RACT regulations. o Title I of the Clean Air Act and subsequent regulations pursuant to the Act, including the USEPA NO(X) SIP Call, established a market based program for NO(X) allowances where units covered by the Act must possess NO(X) allowances to cover their emissions. Massachusetts has adapted regulations allocating allowances to individual units consistent with the Act beginning in 2000. The future cost of NO(X) allowances will be market dependent and could be lower or higher than the current values for such allowances. The exact number of allowances to be required in the future will depend on the utilization of the units in the future. Specific emission rate assumptions and the number of allowances allocated to each facility are presented in the Supplement. The allowance costs assumed in the Projected Operating Results are presented later in this Report. o The Mirant New England Facilities are subject to Title IV of the Clean Air Act (Acid Rain Provisions) whereby each unit must possess SO(2) allowances to cover its emissions beginning in 2000. The future cost of SO(2) allowances will be market dependent and could be lower or higher than the current values for such allowances. The exact number of allowances to be required in the future will depend on the utilization of the units. Specific emission rate assumptions and the number of allowances allocated to each facility are presented in the Supplement. The allowance costs assumed in the Projected Operating Results are presented later in this Report. o Mirant New England has retrofitted Canal Unit 1 with an SCR to reduce NO(X) emissions to levels that would generate NO(X) allowances to allow it to comply with allowance requirements. Plans to retrofit Canal Unit 2 with an SCR have been put on hold until the NO(X) market fully develops in order for Mirant New England to assess the economic viability of SCR installation on Canal Unit 2. o The Kendall Facility must comply with the terms of an Administrative Compliance Order for SO(2) emissions, which was issued by the Massachusetts Department of Environmental Protection ("MADEP") on A-28 March 15, 1995. This order requires the Kendall Facility to limit SO(2) emissions to a rate of 379.6 pounds per hour ("lb/hr") for any single 10-hour period commencing either at 6:00 a.m., 7:00 a.m., or 8:00 a.m. and further limit SO(2) emission for the next 14 hours (i.e., the balance of a 24-hour day) to a rate of 225.4 lb/hr. These restrictions limit the ability of the Kendall Facility to operate at full load. Historically, the Kendall Facility was not required to operate at load factors that would exceed the above limitations. o In November 1999, the USEPA issued NOVs to owners and operators of 32 coal-fired electric generating plants, charging that over many years these plants had been changed or modified in ways that resulted in increased emission of pollutants and that the plants did not obtain new source permits or prevention of significant deterioration permits applicable to new or modified sources. Since the Mirant New England Facilities are gas/oil-fueled facilities, they have not been issued such notices of violation. While we cannot predict future USEPA actions, should such notices of violations be issued to any of the assets, the cost to comply could be substantial. o There are a number of potential future regulations that, if promulgated, could increase capital expenditures and O&M cost at the Mirant New England Facilities. Such potential regulations include MADEP regulations for emission standards for power plants and federal regulations for mercury control, PM(2.5), regional haze, regional visibility, water intake structure regulations, potential ratcheting of SO(2) allowances beyond 2009 and Subtitle D regulations pertaining to the disposal of fuel combustion wastes. The schedule and specific regulations to be promulgated are not presently known; therefore, the impact of such potential regulations has not been incorporated into the Projected Operating Results. MIRANT TEXAS FACILITY Description of the Bosque Facility The Mirant Texas Facility consists of the Bosque generating facility (the "Bosque Facility"), which is owned by Mirant Texas, LP ("Mirant Texas"), an indirect wholly-owned subsidiary of Mirant Generation and is located southwest of Dallas in rural Bosque County, near Laguna Park, Texas, on an approximately 281-acre site. Mirant Texas maintains an administrative office at the Bosque Facility. The Bosque Facility consists of two combustion-turbine generators ("Bosque Units 1 and 2") and a combined-cycle unit under construction ("Bosque Unit 3") with a total net summer generating capacity of 544 MW, as listed in Table 19. Bosque Units 1 and 2 provide peaking generation, while Bosque Unit 3 is expected to provide base-load generation. All units at the Bosque Facility burn natural gas. For the purpose of the Projected Operating Results, we have assumed that the Bosque Unit 3 will begin commercial operation on June 1, 2001. Revenues from Bosque Units 1 and 2 will be derived from the Bosque PPA with Mirant Americas Energy Marketing LP ("MAEM") expiring no earlier than June 1, 2005. Revenues from Bosque Unit 3 will be derived from an additional agreement with MAEM expiring December 31, 2003.

The operating and maintenance programs, including operating procedures and programs; preventive, predictive and corrective maintenance programs and procedures; planning and scheduling requirements and procedures; and reporting and documentation requirements have not been reviewed. The description contained herein has been provided by Mirant Texas. Operating Programs and Procedures Mirant Texas and GE have signed a Long Term Parts and Long Term Service Agreement which includes the Bosque Facility. GE will provide all of the maintenance requirements, including labor and parts, for GE-manufactured turbines at Bosque Units 1, 2 and 3, and will provide heat rate, output, and availability guarantees. GE will also schedule and perform, partially through the Long Term Parts and Long Term Service Agreement, the annual outage maintenance required in accordance with the CT manufacturer's recommendations. The Bosque Facility utilizes Speedtronic Mark V control systems to operate and monitor the CTs. The systems will display and trend most of the important power plant variable parameters. The Bosque Facility operations staff monitors parameters that are indicative of degraded equipment and systems. No major maintenance is presently scheduled for Bosque Units 1 and 2. Major and minor maintenance schedules are dependent on total hours of operation and the number of start cycles. Operating History Operating data for the past six months of operation of the Bosque Facility was provided by Mirant Texas. The historical averages and corresponding future averages are summarized in Table 20. The generation, average annual heat rate, capacity factor, and equivalent availability factor have been estimated by PA Consulting. A more detailed summary of the historical performance results is included in Exhibit A-10 and in the Supplement.

Commercial operation of Bosque Units 1 and 2 began on May 31 and June 1, 2000, respectively. Therefore, less than six months of operating history is available for Bosque Units 1 and 2. Several minor outages and forced trips have occurred on both units during the first five months of operation, however no unusual or significant events have occurred. A-30 Construction Status of Bosque Unit 3 Bosque Unit 3 is currently under construction and is scheduled to commence operation in June 2001. The remaining construction cost is estimated by Mirant Texas to be approximately $47 million as of January 1, 2001. For the purposes of the Projected Operating Results, we believe it is reasonable to assume that Bosque Unit 3 will begin operation on June 1, 2001. We have included the estimated remaining construction of Bosque Unit 3 under the capital expenditures for the Bosque Facility. Environmental Assessment Environmental Site Assessments In 1999, we reviewed the "Hazardous Materials Environmental Assessment Summary Report" dated April 1999 and the Phase I ESA report dated July 1999, prepared for the Bosque Facility by an environmental consultant. As a result of its investigations, the environmental consultant determined that no further investigations were warranted. A more detailed account of the site assessment findings is presented in the Supplement. Because no updated ESAs of previous or recent environmental investigations regarding the potential for site contamination issues at the Bosque Facility site have been provided for our review, we can offer no opinion with respect to potential site contamination issues at the Bosque Facility site, if any, or potential future remediation costs should contamination be found. While we have not independently investigated site conditions, Mirant Texas reported that, to its knowledge, the conditions at the Bosque Facility are materially similar to those presented in the 1999 ESAs. Status of Permits and Approvals We have reviewed the key permits and approvals for the Bosque Facility. A listing of the key permits and approvals is shown in the Supplement. The major permits and approvals required to operate the Bosque Facility have been obtained and are currently valid or are in the process of being renewed, and we are not aware of any technical circumstances that would prevent the renewal of the major permits or approvals. Regulatory Compliance We have reviewed the year 2000 Excess Emissions Reports and wastewater disposal methods and discussed with Mirant Texas and Mirant Generation personnel the Mirant Texas compliance status. The Bosque Facility appears to be in material compliance with the various conditions set forth in the key permits and approvals and consent orders as applicable. We note the following circumstances relative to compliance with permits and approvals that could have an impact on future operations: o The Bosque Facility is subject to Title IV of the Clean Air Act (Acid Rain Provisions) whereby each unit must possess SO(2) allowances to cover its emissions beginning in 2000. However, since the Facility is fueled by natural gas the requirement for SO(2) allowances is not considered significant. STATE LINE FACILITY Description of the State Line Facility The State Line Facility is owned by State Line Energy, LLC ("State Line Energy"), an indirect wholly-owned subsidiary of Mirant Generation. During December 1997, State Line Energy acquired the State Line Facility from Commonwealth Edison Company ("ComEd"). Revenues from the State Line Facility are derived from the State Line Power Purchase Agreement (the "State Line PPA") with ComEd expiring December 30, 2012. The State Line Facility is located in the City of Hammond, Lake County, Indiana adjacent to Lake Michigan on an approximately 73-acre site. The State Line Facility provides base-load generation, utilizing coal for fuel and natural gas for start-up fuel and flame stabilization. Space is available on the site property for expansion, and A-31 the State Line Facility is currently considering the construction of additional units. We have not included any of the costs or revenues associated with these potential new units in the Projected Operating Results. The State Line Facility is comprised of two conventional steam turbine units with a total summer generating capacity of 515 MW as listed in Table 21. The State Line Facility provides base-load generation and utilizes Powder River Basin ("PRB") coal for fuel. Table 21 Unit Characteristics State Line Facility Summer Full Load In-Service Capacity Heat Rate Dispatch Unit Fuel Date (MW) (Btu/kWh) Type ---- ---- ---- ---- --------- ---- Unit 3 PRB-Coal 1955 197 9,933 Base-load Unit 4 PRB-Coal 1962 318 9,985 Base-load --- Total 515 In addition, the State Line Facility has certain common facilities shared by all units such as lake water pumping stations, fuel receiving, storage and handling systems, water treatment systems, warehouses, maintenance shops, a chemistry laboratory, administrative offices, and an electrical switchyard. Operation and Maintenance Operation of the State Line Facility The State Line Facility units range in age from 39 to 46 years. These units have been maintained in conformance with generally accepted industry practices. Components and systems have been replaced as necessary to maintain plant reliability. The technology, design practices and environmental compliance requirements under which these units were installed are significantly different from those existing today. This has required and will continue to require ongoing repair and maintenance of equipment to meet current performance standards. From 1995 to 1998, ComEd undertook certain maintenance activities at the State Line Facility, which included maintenance associated with conveyor belts replacements, coal handling equipment controls systems modifications, coal handling equipment repairs, coal feeder replacement, and partial retubing of the State Line Unit 3 surface condenser. State Line Energy completed the remaining portions of the deferred maintenance in February 1999 primarily through a series of subcontracts. On February 16, 1998, State Line Unit 3 was taken off-line due to a failure of the low-pressure ("LP") steam turbine. On July 28, 1998, during the outage to repair this LP turbine, but while State Line Unit 4 was operating, the State Line Facility suffered a fire. State Line Energy utilized the down time resulting from the fire to replace the State Line Unit 4 boiler floor, install the State Line Unit 3 baghouse and make improvements to the fuel conveying system. State Line Energy also implemented revised cleanliness procedures and made modifications to the conveying system to reduce coal dust generation. State Line Unit 4 was brought back on line on January 31, 1999. State Line Unit 3 was returned to service February 8, 1999. Operating Programs and Procedures State Line Energy utilizes a preventive and predictive maintenance policy at the State Line Facility. Part of this policy is the incorporation of a computerized maintenance management program. State Line Energy also employs a program of cross-training between operations personnel. This program is designed to merge the skills of boiler, turbine, and electrical operators. Vendor training is also included as part of the program. A-32 Operating History Operating data for the past five years of operation of the State Line Facility was provided by State Line Energy. The historical averages and corresponding future averages are summarized in Table 22. The projected generation, average annual heat rate, capacity factor, and equivalent availability factor have been estimated by PA Consulting. A more detailed summary of the historical performance results is included in Exhibit A-10 and in the Supplement.

Environmental Assessment Environmental Site Assessment As part of the acquisition of the State Line Facility, ComEd agreed to indemnify State Line Energy and its affiliates with respect to environmental conditions attributable to the operation of the State Line Facility prior to or on the acquisition date, including the generation, transportation, storage and release of contaminants, discharges and emissions, and fines or penalties related to violations or obligations imposed by environmental law. State Line Energy agreed to indemnify ComEd and its affiliates from the same types of environmental matters that might arise after the closing date. The environmental indemnifications do not have a cap or time limitation. In 1999, we reviewed Phase I and II ESAs prepared by environmental consultants for the State Line Facility regarding environmental issues at the State Line Facility. Because no updated ESAs of previous or recent environmental investigations regarding the potential for site contamination issues at the State Line Facility site have been provided for our review, we can offer no opinion with respect to potential site contamination issues at the State Line Facility site, if any, or potential future remediation costs should contamination be found. While we have not independently investigated site conditions, State Line Energy reported that, to its knowledge, the conditions at the State Line Facility site are materially similar to those presented in the 1999 ESAs. Refer to the Supplement for additional information on previously conducted ESAs. Status of Permits and Approvals We have reviewed the key permits and approvals for the State Line Facility. A listing of the key permits and approvals is shown in the Supplement. The major permits and approvals required to operate the State Line Facility have been obtained and are currently valid or are in the process of being renewed, and we are not aware of any technical circumstances that would prevent the renewal of the major permits or approvals. A-33 Regulatory Compliance We have reviewed 1999 and 2000 excess air emissions reports, the Wastewater Discharge Monitoring Reports for 2000 and discussed with State Line Energy and Mirant Generation personnel the State Line Facility compliance status. The State Line Facility appears to be in material compliance with the various conditions set forth in the key permits and approvals. We note the following circumstances relative to compliance with permits and approvals that could have an impact on future operations. Additional discussion of certain such circumstances is presented in the Supplement. o The State Line Facility is located in an ozone non-attainment area; therefore, NO(X) RACT would generally apply. However, the Chicago area has received a waiver to the RACT requirements from the USEPA. This waiver was granted because it was demonstrated that NO(X) reductions in the Chicago area do not necessarily reduce ozone. This waiver is considered to be potentially contingent or temporary and subject to subsequent modeling or monitoring data, which may show attainment benefits from NO(X) reductions. o Title I of the Clean Air Act and subsequent regulations pursuant to the Act including the NO(X) SIP Call will result in the establishment of a market based program for NO(X) allowances, where units covered by the Act must possess NO(X) allowances to cover their emissions. The State of Indiana is currently developing a Final NO(X) Rule, which will allocate allowances to individual units consistent with the Act beginning in 2004. The State Line PPA with ComEd allows State Line Energy to pass throught the cost of NO(X) allowances for the term of the agreement. It will be necessary for State Line Energy to purchase NO(X) allowances after the expiration of the State Line PPA. The future cost of NO(X) allowances will be market dependent and could be lower or higher than the current values for such allowances. The exact number of allowances to be required in the future will depend on the utilization of the units in the future. The forecasted number of allowances to be allocated to the units and future price assumptions are presented in the Supplement. The allowance costs assumed in the Projected Operating Results are presented later in this Report. o The State Line Facility is subject to Title IV of the Clean Air Act (Acid Rain Provisions) whereby each unit must possess SO(2) allowances to cover its emissions beginning in 2000. The Asset Sale Agreement with ComEd excluded SO(2) allowances attributable to the State Line Facility from the transferred assets. As such, ComEd retained possession of these allowances. However, the State Line PPA with ComEd stipulates that ComEd is to provide the allowances necessary to cover the SO(2) emissions for the term of the agreement. It will be necessary for State Line Energy to purchase SO(2) allowances after the expiration of the State Line PPA. The future cost of SO(2) allowances will be market dependent and could be lower or higher than the current values for such allowances. The exact number of allowances to be required in the future will depend on the utilization of the units. Specific emission rate assumptions and the number of allowances allocated to each facility are presented in the Supplement. The allowance costs assumed in the Projected Operating Results are presented later in this Report. o Title IV of the Clean Air Act also imposes specific NO(X) emission limits that must be met (presumptive limits) by all coal units subject to the Act. The Phase II Acid Rain Permit also requires the State Line Facility to comply with new NO(X) limitations starting in the year 2000 in accordance with USEPA's acid rain regulations. Specific emission rates are presented in the Supplement. o At this point in time, State Line Energy is awaiting the outcome of specific environmental rule making with respect to NO(X) reductions before committing to a specific implementation plan. The decision to implement specific emissions control technology versus purchase of emission allowances is being evaluated based on economics. However, for the purpose of the Projected Operating Results, based on discussions with State Line Energy, we have assumed an installation of an SCR at State Line Unit 4 in 2013. Specific emission rate assumptions used in the Projected Operating Results are given in the Supplement. o In November 1999, the USEPA issued NOVs to owners and operators of 32 coal-fired electric generating plants, charging that over many years these plants had been changed or modified in ways that resulted in increased emission of pollutants and that the plants did not obtain new source permits or prevention of significant deterioration permits applicable to new or modified sources. None of the assets A-34 included herein have been issued such notices of violation. While we cannot predict future USEPA actions, should such notices of violations be issued to any of the assets, the cost to comply could be substantial. o There are a number of potential future regulations that, if promulgated, could increase capital expenditures and O&M cost at the State Line Facility. Such potential regulations include mercury control, PM(2.5), regional haze, regional visibility, water intake structure regulations, potential ratcheting of SO2 allowances beyond 2009 and Subtitle D regulations pertaining to the disposal of fuel combustion wastes. The schedule and specific regulations to be promulgated are not presently known; therefore, the impact of such potential regulations has not been incorporated into the Projected Operating Results. MIRANT WISCONSIN FACILITY Description of the Neenah Facility The Mirant Wisconsin Facility consists of the Neenah generating facility (the "Neenah Facility"), which is owned by Mirant Neenah, LLC ("Mirant Neenah"), an indirect wholly-owned subsidiary of Mirant Generation. The Neenah Facility is newly constructed and began commercial operation during 2000. Mirant Neenah maintains an administrative office at the plant. Revenues from the Neenah Facility are derived from a Power Purchase Agreement with Wisconsin Electric Power Company ("Wisconsin Electric") that expires July 1, 2008. The Neenah Facility is located just east of the city of Neenah, in semi-urban Winnebago County, Wisconsin, on an approximately 26-acre site. Mirant Neenah has considered converting one or both generating units from simple cycle to combined cycle operation. We have not included any of the costs or revenues associated with this potential conversion in the Projected Operating Results. The Neenah Facility is comprised of two simple-cycle combustion turbine generators with a total summer generating capacity of 309 MW as listed in Table 23. The Neenah Facility provides peaking generation and is capable of utilizing both natural gas and No. 2 oil for fuel. Table 23 Unit Characteristics Neenah Facility Summer Full Load In-Service Capacity Heat Rate Dispatch Unit Fuel Date (MW) (Btu/kWh) Type ---- ---- ---- ---- --------- ---- Unit 1 Gas/No. 2 Oil 2000 154.5 10,614 Peaking Unit 2 Gas/No. 2 Oil 2000 154.5 10,614 Peaking ----- Total 309.0 Operation and Maintenance Operation of the Neenah Facility We have not visited the Neenah Facility. The operations and maintenance programs, including operating procedures and programs; preventive, predictive and corrective maintenance programs and procedures; planning and scheduling requirements and procedures; and reporting and documentation requirements have not been reviewed. The description contained herein has been provided by Mirant Wisconsin. Operating Programs and Procedures Plant staffing presently consists of two operations and maintenance personnel, who report to the Facility Manager, Midwest CT Operations of Hammond, Indiana. The two units at the Neenah Facility are operated utilizing two operating shifts. Each shift consists of one operator each for two shifts during peak periods. During the off-peak season, one operator will be at the plant working one shift only unless the plant is dispatched. Plant supervision, technical support, and back-up support will be available from the State Line Facility. A-35 Mirant Neenah and General Electric Corporation ("GE") have signed a Long Term Parts and Long Term Service Agreement which includes the Neenah Facility. GE provides all of the maintenance requirements, including labor and parts, for Neenah Units 1 and 2, and provides heat rate, output, and availability guarantees. GE also schedules and performs, partially through the Long Term Parts and Long Term Service Agreement, the annual outage maintenance required in accordance with the combustion turbine manufacturer's recommendations. The Neenah Facility utilizes a Speedtronic Mark V control system to operate and monitor the combustion turbine generators. This system displays and monitors most of the important power plant variable parameters. Neenah Facility operations staff monitors parameters that are indicative of degraded equipment and systems. The Maximo maintenance management system ("Maximo") is used as the work order system, inventory management system and preventive maintenance system and the database is currently under development. Maximo is a purchased system and is used widely in the power industry. As major maintenance is dictated by the hours of operation and the Neenah Facility is a peaking plant, there is no major maintenance scheduled in the near future for Neenah Units 1 and 2. Major and minor maintenance schedules are dependent on total hours of operation and the number of start cycles. Operating History Initial commercial operation of the Neenah Facility began on May 8, 2000; therefore, less than seven months of operating history is available for Neenah Units 1 and 2. Normal minor outages and start-up trips have occurred on both units during the first six months of operation, however no unusual or significant events have occurred. Operating data for the past several months of operation of the Neenah Facility was provided by Mirant Neenah. The historical averages and corresponding future averages are summarized in Table 24. The projected generation, average annual heat rate, capacity factor, and equivalent availability factor have been estimated by PA Consulting. A more detailed summary of the historical performance results is included in Exhibit A-10 and in the Supplement. Table 24 Operating History Neenah Facility Historical Projected Average Average (2000) (2001-2020) ------ ----------- Net Capability Rating (MW)(1) 309 309 Net Generation (GWh)(2) 159.2 74.3 Annual Net Heat Rate (Btu/kWh)(3) 11,539 11,396 Net Capacity Factor (%)(3) 9.1 2.8 Equivalent Availability Factor (%)(3) 97.8 96.0 -------------------- (1) Summer rating based on performance test results, August 2000. (2) Represents six-month total from monthly reports. (3) Six-month average from monthly reports. Environmental Assessment Environmental Site Assessment In 1999, we reviewed the Phase I ESA dated April 1999, prepared by an environmental consultant for the Neenah Facility site. The environmental consultant's site visit identified no evidence of stained soils, hazardous substance storage, or hazardous waste disposal at the property. A more detailed account of the site assessment findings is presented in the Supplement. Because no updated ESAs of previous or recent environmental investigations regarding the potential for site contamination issues at the Neenah Facility site have been provided for our review, we A-36 can offer no opinion with respect to potential site contamination issues at the Neenah Facility site, if any, or potential future remediation costs should contamination be found. While we have not independently investigated site conditions, Mirant Neenah reported that the conditions at the Neenah Facility site are materially similar to those presented in the 1999 ESAs. Status of Permits and Approvals We have reviewed the key permits and approvals for the Neenah Facility. A listing of the key permits and approvals is shown in the Supplement. The major permits and approvals required to operate the Neenah Facility have been obtained and are currently valid or are in the process of being renewed, and we are not aware of any technical circumstances that would prevent the renewal of the major permits or approvals. Regulatory Compliance We have reviewed the 2000 Environmental Emissions Compliance Test for the Neenah Facility and the wastewater disposal methods and discussed with Mirant Neenah and Mirant Generation personnel the Mirant Neenah compliance status. The Neenah Facility appears to be in material compliance with the various conditions set forth in the key permits and approvals. We note the following circumstances relative to compliance with permits and approvals that could have an impact on future operations. Additional discussion of certain such circumstances is presented in the Supplement. o USEPA named Wisconsin as one of the states subject to the requirement under USEPA's SIP Call to establish a market based program for NO(X) allowances where electric generating units must possess NO(X) allowances to cover their emissions. Subsequently, a federal appeals court ruled that USEPA should drop Wisconsin from the SIP Call. However, Wisconsin must still comply with the National Ambient Air Quality Standards for ozone and in September of 2000 the state Department of Natural Resources ("DNR") recommended adopting a plan for eight counties in southeast Wisconsin to reduce NO(X) emissions and bring the counties into compliance with the 1-hour ozone standard by the year 2007. Winnebago County, where the Neenah Facility is located, is not included in the recommended plan. o The Neenah Facility is subject to Title IV of the Clean Air Act (Acid Rain Provisions) whereby each unit must possess SO(2) allowances to cover its emissions beginning in 2000. However, since the Facility is fueled by natural gas the requirement for SO(2) allowances is not considered significant. PROJECTED OPERATING RESULTS We have reviewed the historical operating information, estimates and projections of electrical generating capacity, fuel consumption, and capital and operating costs of the Mirant Generation Facilities made available to us by Mirant Generation. On the basis of such data, we have prepared the Projected Operating Results. A portion of the generation from the Mirant Generation Facilities is to be sold under contract, which we have reviewed and projected; however, the majority has been assumed to be sold directly to the market at market rates, which have been estimated by PA Consulting. Expenses for the plants consist primarily of the costs of fuel, including transportation, as estimated by PA Consulting, and operating and maintenance expenses, as estimated by Mirant Generation. The interest payments on the Notes, as well as other Mirant Generation debt, have been estimated by Representative of the Initial Purchasers. The Series A Notes have been assumed to mature on April 15, 2006 and the Series B Notes have been assumed to mature on April 15, 2011. Mirant Generation has assumed that the Notes will be refinanced upon maturity; therefore, the Projected Operating Results are presented for each calendar year beginning January 1, 2001 through December 31, 2020, a period approximately ten years beyond the term of the Notes. Projected revenues and expenses have been set forth in the Projected Operating Results presented in Exhibit A-1. The Projected Operating Results have been prepared using assumptions and considerations set forth in this Report and the footnotes to Exhibit A-1. A-37 Annual Operating Revenues Revenues from Contract Electricity Sales The following is a brief description of the revenues derived by Mirant Generation from contract electricity sales. Mirant California The Mirant California Facilities operate under Reliability Must Run ("RMR") contracts with the California Independent System Operator ("California ISO"). Under these contracts, the Mirant California Facilities receive a capacity payment ("RMR Payment"), which has been projected by PA Consulting. The terms of the RMR Payments are currently in dispute. PA Consulting has assumed that the Mirant California Facilities will receive a portion of the RMR Payments through 2008. For additional discussion regarding the RMR Payments, please refer to PA Consulting's report and the section of the Offering Circular entitled "Our Business - Legal Proceedings". Mirant New England All capacity, energy and ancillary services from Canal Unit 1, is made available and sold to four purchasers through October 10, 2002 under power contracts between Mirant Canal and Cambridge Electric Light Company and Commonwealth Electric Company (jointly), Boston Edison Company, Montaup Electric Company and Mirant New England, LLC, an affiliate of Mirant Generation. Each of the four power contracts calls for the sale of 25 percent of the capacity and energy from Canal Unit 1. The demand charge under the power contracts is a fixed schedule of charges. There is an additional schedule of fixed payments for the installation and operation of a SCR for Canal Unit 1. Canal Unit 1 is dispatched by ISO-New England. The energy charge is a pass-through of fuel costs for Canal Unit 1, which is borne equally by the four power purchasers. For the purposes of the Projected Operating Results, we have assumed capacity factors and fuel prices as estimated by PA Consulting. Mirant Kendall sells steam to a subsidiary of NSTAR pursuant to a Steam Supply Agreement dated October 1, 2000 (the "Kendall Steam Agreement"). The Kendall Steam Agreement contains a demand charge, consumption charge, and condensate return charge and expires after the term of the Projected Operating Results; however, either party may terminate the agreement with 24 months' prior notice. The consumption charge is indexed to a specified fuel price. For the purposes of the Projected Operating Results, we have assumed a steam demand and consumption consistent with historical usage as reported by Mirant Kendall. For the purpose of projecting the consumption charge under the Kendall Steam Agreement, we have assumed that the contract fuel index will increase according to the fuel price projection for the Kendall Facility as projected by PA Consulting. Mirant Texas Mirant Texas entered into two Tolling Agreements with MAEM dated October 8, 1999 and June 27, 2000 (collectively, the "Bosque PPA") for the purchase of the output of Bosque Units 1 and 2 and Bosque Unit 3, respectively. The Bosque PPA terminates with respect to Bosque Units 1 and 2 on June 1, 2005 and with respect to Bosque Unit 3 on December 31, 2003. We have assumed that MAEM will take all the power available from Bosque Units 1, 2 and 3 during the respective terms of the Bosque PPA. The Bosque PPA provides for a series of payments to be provided by MAEM to Mirant Texas in exchange for a pre-determined amount of power (at a selected heat rate) and the fuel necessary to provide that output. These payments include a capacity payment, an O&M charge, and a run charge for Bosque Units 1 and 2 and a capacity and O&M payment for Bosque Unit 3. The capacity payments are adjusted to reflect the difference between actual performance and a guaranteed capacity, a guaranteed heat rate, and a guaranteed annual average equivalent availability. There are deadbands associated with the guaranteed output and heat rate. The annual capacity charges received by Mirant Texas are adjusted up or down for actual output and heat rate above the deadbands. The guaranteed equivalent availability is adjusted depending on the hours of operation in a year. The annual capacity charge received by Mirant Texas is adjusted based upon the difference between the annual equivalent availability and the guaranteed equivalent availability. A-38 MAEM will provide at no cost to the Mirant Texas all fuel required by the facility, including all fuel required for normal startup and testing, and will pay all associated transportation cost to the fuel delivery points. MAEM will pay Mirant Texas an annual O&M charge for Bosque Units 1 and 2 based on a predetermined schedule and the ratio of the cumulative hours of operation and cumulative number of times each unit is started. The O&M charge for Bosque Unit 3 is fixed through December 31, 2003. For the purposes of the Projected Operating Results, we have assumed that the number of starts will be as estimated by PA Consulting. MAEM will also pay Mirant Texas a run charge, which is based upon the total number of hours that each unit has operated since commercial operation, regardless if the unit was synchronized and producing electricity, but excluding hours operated during optional capacity or heat rate tests. For the Projected Operating Results, we have assumed that: (1) the demonstrated capacity will be greater than the guaranteed capacity by approximately 55 MW; (2) the projected annual average heat rates will be as estimated by PA Consulting; (3) an equivalent availability of 98 percent during June through September and 95 percent for the remainder of the year for Bosque Units 1 and 2 and an equivalent availability of 97 percent during June through September and 94 percent for the remainder of the year for Bosque Unit 3; and (4) the hours for which the run charge is applicable will be equal to the dispatched hours as projected by PA Consulting. State Line Energy The State Line PPA was entered into on April 17, 1996, and sets forth the terms and conditions under which ComEd schedules the operation of and purchases electricity from the State Line Facility for a term of 15 years ending December 30, 2012. The State Line PPA allows ComEd the sole and exclusive right to dispatch the delivery of electric energy from the State Line Facility at a rate up to the State Line Facility's net dependable capacity of 515 MW. In the event excess capacity would exist from time to time, ComEd has the first right of refusal for the purchase of the energy generated from such excess capacity. The State Line PPA was amended in February 2000 and again in September 2000, to increase the State Line Facility's net dependable capacity available for dispatch by ComEd from the original amount of not less than 490 MW to not less than 515 MW through the term of the State Line PPA. Under the State Line PPA, State Line Energy receives revenues from the sale of capacity and energy to ComEd, consisting of a capacity charge, a non-fuel energy charge and various miscellaneous charges. Components of the capacity charge and energy charge are escalated annually by an O&M adjustment factor. The capacity charge is further adjusted by a seasonal availability adjustment factor intended to measure performance of the State Line Facility relative to targeted equivalent availability factors. The specified equivalent availability factor is set by the State Line PPA after the first two Contract Years at 90 percent for summer months and 75 percent for non-summer months through the term of the State Line PPA. ComEd supplies all coal necessary for the operation of the State Line Facility during the term of the State Line PPA. In addition, ComEd is responsible for the transfer of sufficient SO(2) allowances from its system necessary for the emission of SO(2) from the State Line Facility resulting from the consumption of coal supplied by ComEd during the term of the State Line PPA. ComEd is not obligated to provide SO(2) allowances to the State Line Facility beyond the term of the State Line PPA. In the event additional NO(X) emissions requirements are imposed on the State Line Facility, State Line Energy shall be entitled to a monthly NO(X) compliance cost payment during the term of the State Line PPA intended to reimburse State Line Energy for the capital and/or incremental operational cost increases incurred by State Line Energy. If State Line Energy is required to install capital equipment to comply with NO(X) regulations, under the terms of the State Line PPA, ComEd will be required to pay State Line Energy a monthly payment based on the amortization of the capital costs. Such additional monthly payment would be payable during the term of the State Line PPA, which expires on December 30, 2012, but the amortization of the capital costs would be calculated from the in-service date of the capital addition until December 30, 2022. For the Projected Operating Results, we have assumed that: (1) the net dependable capacity will be equal to 515 MW; and (2) equivalent availability factors will be equal to the specified equivalent availability factors set forth in the State Line PPA. A-39 Mirant Neenah The Neenah Facility sells power to Wisconsin Electric under a Power Purchase Agreement between Mirant Neenah and Wisconsin Electric dated August 28, 1998 (the "Neenah PPA"). The Neenah PPA provides for provisions of fuel and the purchase of the output from the first and second units of the Neenah Facility. The term of the Neenah PPA ends on July 1, 2008. The Neenah PPA provides for a series of payments to be provided by Wisconsin Electric to Mirant Neenah in exchange for a pre-determined amount of power (at a selected heat rate) and the fuel necessary to provide that output. These payments include a start charge and a running charge. The capacity payment is adjusted to reflect the difference between actual performance and a guaranteed capacity, a guaranteed heat rate, and a guaranteed annual average equivalent availability. There are deadbands associated with the guaranteed output and heat rate. The annual capacity charge received by Mirant Neenah is adjusted up or down for actual output and heat rate above the deadbands. The guaranteed equivalent availability is adjusted depending on the hours of operation in a year. The annual capacity charge received by Mirant Neenah is adjusted based upon the difference between the annual equivalent availability and the guaranteed equivalent availability. Wisconsin Electric provides the fuel required by the Neenah Facility to meet the obligations of the Neenah PPA at no cost to Mirant Neenah, and will pay all associated transportation costs to the Neenah Facility. In addition to the capacity payment, Wisconsin Electric pays a start-up charge and a running charge. The start-up charge is dependent upon the cumulative number of successful normal start-ups and is limited to one successful start during any dispatch period. The running charge is assessed on each combustion turbine and is dependent on the fuel type utilized for each hour. Both the start-up charge and running charge are adjusted annually for inflation. For the purposes of the Projected Operating Results, we have assumed that the number of starts will be as estimated by PA Consulting. For the Projected Operating Results, we have assumed that: (1) the demonstrated capacity will be equal to the guaranteed capacity; (2) the annual average heat rates will be estimated by PA Consulting; (3) an equivalent availability of 96.0 percent per year; and (4) the number of starts and hours for which the running charge is applicable will be determined by PA Consulting. Revenues from Market Electricity Sales All non-contract energy generated by the Mirant Generation Facilities has been assumed to be sold to the market at market electricity rates. Market electricity rates were estimated by PA Consulting in 2000 dollars for each of the Mirant Generation Facilities and have been adjusted for inflation. For the purposes of the Projected Operating Results, the general inflation rate has been assumed to be 2.6 percent per year based on a March 10, 2001 projection prepared by Blue Chip Economic Indicators. Annual Operating Expenses Fuel Costs All of the Mirant Generation Facilities purchase fuel on a short-term basis at rates which are at or near market rates. PA Consulting has projected long-term fuel prices. For the purposes of the Projected Operating Results, we have assumed fuel prices equal to the projections prepared by PA Consulting in 2000 dollars and adjusted for inflation. Operating and Maintenance Costs For the purposes of developing the Projected Operating Results, operating and maintenance expenses for the Mirant Generation Facilities have been estimated by Mirant Generation. These estimates include annual costs for payroll, materials and supplies, outside services, including contractors, and variable operating and maintenance expenses. Mirant Generation's estimate of operating and maintenance expenses for the coal plants include the costs of ash disposal, net of ash sold. Mirant Generation has projected that the cost of operating and maintaining the Lovett, A-40 Kendall, Canal and Potrero Facilities will decrease over the next few years as efficiencies are implemented. All operation and maintenance expenses have been provided in 2001 dollars and have been assumed to escalate at the general rate of inflation. Although we have not reviewed each individual expense constituting Mirant Generation's estimate of operating and maintenance expenses and capital expenditures and the methodology used to develop the estimates, we have reviewed the combined projection of operating and maintenance expenses and capital expenditures in comparison to the costs of similar plants with which we are familiar. Based on our review, we are of the opinion that Mirant Generation's estimates of the costs of operating and maintaining the Mirant Generation Facilities, including provision for capital expenditures and major maintenance, are within the range of the costs of similar plants with which we are familiar. Emissions Allowances Mirant Generation has acquired or has been allocated the SO(2) and NO(X) allowances associated with the Mirant Generation Facilities. We have included the cost of allowances as an additional operating expense for the Mirant Generation Facilities. In the event that excess allowances are available for sale, we have assumed that Mirant Generation would sell the allowances at market prices. The deficit or excess of allowances has been estimated based on the assumed emission rates as estimated by Mirant Generation, the capacity factors projected by PA Consulting, and the allocated SO(2) and NO(X) allowances. The market SO(2) allowance price has been assumed to be $150 per ton in 2001 dollars and has been assumed to increase thereafter at the rate of inflation. Market NO(X) allowance prices have been assumed to be $1,000 per ton through 2002, $2,300 in 2003, $2,000 in 2004 and $1,700 in 2005 and assumed to increase thereafter at the rate of inflation. It should be noted that PA Consulting has assumed SO(2) and NO(X) allowance prices that are significantly higher than those assumed in the Projected Operating Results. In the event that the actual allowance prices are as assumed by PA Consulting, the projected minimum and average interest coverage ratios over the term of the Notes would decrease by approximately 0.07 and 0.05, respectively. General and Administrative and Other Expenses Mirant Generation has estimated certain general and administrative costs which have been included in the Projected Operating Results. These costs include, among other things, support services such as power marketing, computer systems and services, human resources, and accounting. These expenses have been assumed to increase at the general rate of inflation. In addition, Mirant Generation has estimated other expenses, which have also been included in the Projected Operating Results. Property taxes have been estimated by Mirant Generation for 2001 and have been assumed to escalate at the rate of inflation, with the exception of the Mirant New York Facilities, for which the property taxes have been assumed to remain flat based on Mirant Generation's expectation of its current negotiations with the local authorities. Mirant Generation's property tax estimates for the Chalk Point, Dickerson, and Morgantown Facilities reflect exemptions beginning in 2001 for machinery used to generate electricity. Capital Expenditures For the purposes of the Projected Operating Results, Mirant Generation has estimated the costs of capital improvements to the Mirant Generation Facilities. These capital expenditures include the cost of certain environmental control equipment assumed by Mirant Generation to be added at certain of the Mirant Generation Facilities; however, Mirant Generation and its affiliates regularly reevaluates cost-effective alternatives to achieve compliance with future environmental regulations. These improvements include the installation of: (1) low-NO(X) burners at Chalk Point Units 1 and 2 in 2002; (2) SCRs at Chalk Point Units 1 and 2 in 2006 and 2008, respectively; (3) SOFA systems at Dickerson Units 1, 2 and 3 in 2002, 2003, and 2003, respectively; (4) SCRs/SNCRs at Morgantown Units 1 and 2 in 2006 and 2008, respectively; (5) low-NO(X) burners and SOFA systems at Potomac River Units 3, 4 and 5 in 2007, 2007, and 2008, respectively; (6) an SCR at State Line Unit 4 in 2013; (7) Gunderbooms at the Lovett Facility in 2003; (8) Gunderbooms at the Contra Costa and Pittsburg Facilities in 2003; (9) SCRs at A-41 Pittsburg Units 1, 2, 3 and 4 in 2003; (10) low-NO(X) burners and an SCR at Pittsburg Unit 5 in 2001 and 2002, respectively; (11) SCRs at Pittsburg Unit 6 and 7 in 2002 and 2003, respectively; (12) an SCR at Potrero Unit 3 in 2004; (13) low-NO(X) burners and an SCR at Contra Costa Unit 6 in 2001 and 2003, respectively; and (14) an SCR at Contra Costa Unit 7 in 2001. Annual Interest We have included interest on all Mirant Generation debt. In addition to the Notes, Mirant Generation has previously incurred additional debt, a portion of which is assumed to be refinanced with additional debt by the end of 2001 and a portion of which is assumed to be refinanced with additional debt by the end of 2003. We have included interest payments on the principal amount of the Notes and the other Mirant Generation debt at interest rates estimated by Representative of the Initial Purchsers resulting in a weighted average interest rate ranging over the term of the Notes from approximately 7.1 to 8.2 percent per year. The scheduled amortization of the Series A and Series B Notes is assumed to consist of single payments due on April 15, 2006 and April 15, 2011, respectively. Mirant Generation has assumed that the Notes will be refinanced upon maturity at the same principal amount and interest rate. No additional costs of issuance have been included. We have also included interest on a revolving credit facility to be used to fund certain of the capital expenditures. Mirant Generation has identified certain capital expenditures to be funded through the revolving credit facility for the Base Case Projected Operating Results and the sensitivities. Interest on the revolving credit facility has been estimated by Representative of the Initial Purchsers. No principal amortization of any of the Mirant Generation debt has been assumed. Interest Coverage Interest coverage has been calculated as the cash available for debt service divided by interest on all Mirant Generation debt. On the basis of our studies and analyses of the Mirant Generation Facilities and the assumptions set forth in this Report, we are of the opinion that, for the Base Case Projected Operating Results, the projected revenues from the sale of electricity are adequate to pay annual operating and maintenance expenses (including capital expenditures and major maintenance), fuel expense, and other operating expenses. Such revenues provide an annual interest coverage on the Notes of at least 2.70 times the annual interest requirement in each year during the term of the Notes and a weighted average coverage of 3.21 times the annual interest requirement over the term of the Notes. There is insufficient cash available after the payment of interest in 2006 and 2011 to repay the entire principal due on the Notes. Mirant Generation has assumed that the Notes will be refinanced upon maturity. The weighted average interest coverage has been calculated as the total net operating revenues less capital expenditures over the term of the Notes divided by the total interest payments over the term of the Notes. Annual interest coverages through December 31, 2020 are presented in Exhibit A-1. Sensitivity Analyses Due to the uncertainties necessarily inherent in relying on assumptions and projections, it should be anticipated that certain circumstances and events may differ from those assumed and described herein and that such will affect the results of our Base Case Projected Operating Results for the Mirant Generation Facilities. In order to demonstrate the impact of certain circumstances on the Base Case Projected Operating Results, certain sensitivity analyses have been developed. It should be noted that other examples could have been considered and those presented are not intended to reflect the full extent of possible impacts on the Mirant Generation Facilities. The sensitivities are not presented in any particular order with regard to the likelihood of any case actually occurring. In addition, no assurance can be given that all relevant sensitivities have been presented, that the level of each sensitivity is the appropriate level for testing purposes, or that only one (rather than a combination of more than one) of such variations or sensitivities could impact the Mirant Generation Facilities in the future. These sensitivity analyses present the Projected Operating Results assuming, respectively, that: (a) the market electricity prices, energy sales, and fuel prices are equal to the "Low Fuel Price" scenario prepared by PA Consulting; (b) the market electricity prices, energy sales, and fuel prices are equal to the "High Fuel Price" scenario prepared by PA Consulting; (c) the market electricity prices, energy sales, and fuel prices are equal to the "Capacity Overbuild" case prepared by PA Consulting; (d) the market electricity prices, energy sales, and fuel prices are equal to the "High Hydro" case prepared by PA Consulting; (e) the market electricity prices are reduced, with A-42 corresponding decreases in fuel prices as projected by PA Consulting, such that the interest coverage on Mirant Generation debt is equal to 1.00 in all years; (f) the availability of the Mirant Generation Facilities is reduced by 5 percentage points; (g) the heat rates of the Mirant Generation Facilities are 5 percent higher than that assumed in the Base Case; and (h) the non-fuel related operating expenses of the Mirant Generation Facilities are 10 percent higher than that assumed in the Base Case. The sensitivity analyses are presented as Exhibits A-2 through A-9 to this Report. For the purposes of (a), (b), (c) and (d), PA Consulting has prepared additional projections of dispatch and market electricity prices. The assumptions used in the various market price scenarios are discussed in detail in the PA Consulting report attached as Annex B to the Offering Circular. In addition, for the purposes of (e), PA Consulting has estimated the reduction in fuel prices for each unit based upon the reduction in the market electricity price. Based on discussions with PA Consulting, market electricity prices, energy sales, and fuel prices have been assumed to be the same as the Base Case for the purposes of (f), (g), and (h). It should be noted that case (e), the breakeven market price case, has been prepared assuming corresponding decreases in fuel prices as projected by PA Consulting. This case results in a weighted average decrease in market electricity prices of approximately 26 percent to reduce interest coverage on Mirant Generation debt of 1.00 in each year during the term of the Notes. We have not included this fuel correlation in similar breakeven analyses in previous reports. We have included this case at Mirant Generation's request and have not determined whether the assumed level of correlation between the market electricity prices and fuel costs is reasonable. We have performed an additional breakeven analysis assuming no fuel correlation, which has resulted a weighted average decrease in market electricity prices of approximately 20 percent to reduce interest coverage on Mirant Generation debt of 1.00 in each year during the term of the Notes.

(2) Represents coverage on the interest payments on the Notes assuming the market electricity price is reduced, with corresponding decreases in fuel prices as estimated by PA Consulting, such that the total operating revenue results in an interest coverage of 1.00 in all years. (3) Represents minimum interest coverage during any year over the term of the Notes assuming no principal repayment. (4) Represents the weighted average interest coverage over the term of the Notes assuming no principal repayment. A-43 In addition to these sensitivity cases, Mirant Generation has requested that we calculate the interest coverages removing any contribution from: (1) Mirant Mid-Atlantic and (2) Mirant California. In the case where Mirant Mid-Atlantic makes no contribution to Mirant Generation, the projected minimum and average interest coverage ratios over the term of the Notes would decrease to 1.02 and 1.50, respectively. In the case where Mirant California makes no contribution to Mirant Generation, the projected minimum and average interest coverage ratios over the term of the Notes would decrease to 2.08 and 2.43, respectively. PRINCIPAL CONSIDERATIONS AND ASSUMPTIONS USED IN THE PROJECTION OF OPERATING RESULTS In the preparation of this Report and the opinions that follow, we have made certain assumptions with respect to conditions which may exist or events which may occur in the future. While we believe these assumptions to be reasonable for the purpose of this Report, they are dependent upon future events, and actual conditions may differ from those assumed. In addition, we have used and relied upon certain information provided to us by sources which we believe to be reliable. While we believe the use of such information and assumptions to be reasonable for the purposes of our Report, we offer no other assurances thereto and some assumptions may vary significantly due to unanticipated events and circumstances. To the extent that actual future conditions differ from those assumed herein or provided to us by others, the actual results will vary from those projected herein. This Report summarizes our work up to the date of the Report. Thus, changed conditions occurring or becoming known after such date could affect the material presented to the extent of such changes. The principal considerations and assumptions made by us in developing the Base Case Projected Operating Results and the principal information provided to us by others include the following: 1. As Independent Engineer, we have made no determination as to the validity and enforceability of any contract, agreement, rule, or regulation applicable to the Mirant Generation Facilities and its operations. However, for purposes of this Report, we have assumed that all such contracts, agreements, rules, and regulations will be fully enforceable in accordance with their terms and that all parties will comply with the provisions of their respective agreements. 2. Our review of the design of the Mirant Generation Facilities was based on information provided by Mirant Generation and its affiliates and subsidiaries. 3. Mirant Generation and its affiliates and subsidiaries will maintain the Mirant Generation Facilities in accordance with good engineering practice, will perform all required major maintenance in a timely manner, and will not operate the equipment to cause it to exceed the equipment manufacturers' recommended maximum ratings. 4. Mirant Generation and its affiliates and subsidiaries will employ or contract for qualified and competent operations, maintenance and general management personnel and will provide such personnel to Mirant Generation, which will generally operate the Mirant Generation Facilities in a sound and businesslike manner. 5. Inspections, overhauls, repairs and modifications are planned for and conducted in accordance with manufacturers' recommendations, and with special regard for the need to monitor certain operating parameters to identify early signs of potential problems. 6. All licenses, permits and approvals, and permit modifications necessary to operate the Mirant Generation Facilities have been, or will be, obtained on a timely basis and any changes in required licenses, or permits and approvals will not require reduced operation of, or increased costs to, the Mirant Generation Facilities. 7. The CPI-U, general inflation, and all related indices will increase at a rate of 2.6 percent per year based on a March 10, 2001 projection prepared by Blue Chip Economic Indicators. A-44 8. Mirant Generation and its affiliates and subsidiaries will operate the Mirant Generation Facilities at the load levels projected by PA Consulting, resulting in the annual average heat rates assumed in the Projected Operating Results. The quantities of market electricity sales, number of starts, market prices of electricity, and the cost of fuel for the Mirant Generation Facilities will be as projected by PA Consulting, including the receipt of RMR Payments for the Mirant California Facilities through 2008. 9. All revenue from the Mirant Generation Facilities beginning January 1, 2001 will be available to pay interest on the Notes. 10. For the purposes of estimating operating expenses, the price of SO(2) allowances will be $150 per ton in 2001 dollars and will increase thereafter at the rate of inflation. The price of NO(X) emissions allowances will be $1,000 per ton through 2002, $2,300 per ton in 2003, $2,000 per ton in 2004, and $1,700 per ton in 2005 and will increase thereafter at the rate of inflation. 11. The non-fuel operating and maintenance expenses, including the cost of major maintenance, will be consistent with the projection provided by Mirant Generation in 2000 dollars, and will increase at the assumed change in the general inflation rate, except for property taxes, which have been assumed to remain constant, and the lease payments for the Mirant Mid-Atlantic Facilities. 12. The capital improvements to the Mirant Generation Facilities assumed in the Projected Operating Results will be implemented at the estimated costs and in the time frames proposed by Mirant Generation. Certain of the capital expenditures, as identified by Mirant Generation, will be funded through a revolving credit facility. 13. The interest rates on Mirant Generation debt, including the Notes, will be as estimated by Representative of the Initial Purchasers, resulting in a weighted average interest rate ranging over the term of the Notes from approximately 7.1 to 8.2 percent per year. 14. The Series A and Series B Notes will be refinanced upon maturity in 2006 and 2011, respectively, as assumed by Mirant Generation, at the same interest rates as the Notes, as estimated by Representative of the Initial Purchasers. CONCLUSIONS Set forth below are the principal opinions we have reached after our review of the Mirant Generation Facilities. For a complete understanding of the estimates, assumptions, and calculations upon which these opinions are based, the Report and the Supplement should be read in their entirety. On the basis of our review and analyses of the Mirant Generation Facilities and the assumptions set forth in this Report, we are of the opinion that: 1. The sites for the Mirant Generation Facilities are suitable for the Mirant Generation Facilities' continued operation. 2. The Mirant Generation Facilities have been operated and maintained in accordance with generally accepted industry practices, and the technologies in use at the Mirant Generation Facilities are sound, proven conventional methods of electric generation. If operated and maintained as proposed by Mirant Generation and the project companies, the Mirant Generation Facilities should be capable of meeting the requirements of the respective power purchase agreements and currently applicable environmental permit requirements. Furthermore, all off-site requirements of the Mirant Generation Facilities have been adequately provided for, including fuel supply, water supply, ash and wastewater disposal, and electrical interconnection. 3. The Mirant Generation Facilities should be capable of achieving the projected annual average net capacities, annual equivalent availability factors, net generation, and net heat rates assumed in the Projected Operating Results. A-45 4. Provided that: (1) the units are operated and maintained by Mirant Generation in accordance with the policies and procedures as presented by Mirant Generation; (2) all required renewals and replacements are made on a timely basis as the units age; and (3) fuels burned by the units are within the expected ranges with respect to quantity and quality, the Mirant Generation Facilities should have useful lives of at least 20 years. 5. Through either the experience of the existing personnel or other Mirant operating subsidiaries, Mirant Generation has demonstrated the capability to operate the Mirant Generation Facilities. With the exception of the Neenah and Bosque Facilities, for which operating procedures have not been reviewed, the operating programs and procedures which are currently in place for the Mirant Generation Facilities are consistent with generally accepted practices in the industry, and Mirant Generation has incorporated organizational structures that are comparable to other facilities using similar technologies. 6. The ESAs and updated report for the sites of the Mirant Mid-Atlantic Facilities were conducted in a manner consistent with industry standards, using comparable industry protocols for similar studies with which we are familiar. With respect to the other Mirant Generation Facilities, because no updated ESAs of previous or recent environmental investigations regarding the potential for site contamination issues at the other sites have been provided for our review, we can offer no opinion with respect to potential site contamination issues at the sites of the other Mirant Generation Facilities, if any, or potential future remediation costs should contamination be found. 7. The major permits and approvals required to operate the Mirant Generation Facilities have been obtained and are currently valid or are in the process of being renewed, and we are not aware of any technical circumstances that would prevent the renewal of the major permits or approvals. 8. The Mirant Generation Facilities appear to be in material compliance with the various conditions set forth in the key permits and approvals and consent orders as applicable. 9. Mirant Generation's estimates of the costs of operating and maintaining the Mirant Generation Facilities, including provision for capital expenditures and major maintenance, are within the range of the costs of similar plants with which we are familiar. 10. For the Base Case Projected Operating Results, the projected revenues from the sale of electricity are adequate to pay annual operating and maintenance expenses (including capital expenditures and major maintenance), fuel expense, and other operating expenses. Such revenues provide an annual interest coverage on the Notes of at least 2.70 times the annual interest requirement in each year during the term of the Notes and a weighted average coverage of 3.21 times the annual interest requirement over the term of the Notes. There is insufficient cash available after the payment of interest in 2006 and 2011 to repay the entire principal due on the Notes. Mirant Generation has assumed that the Notes will be refinanced upon maturity. Respectfully submitted, R. W. BECK, INC.
