GENERAL

         CogenAmerica, formerly known as NRG Generating (U.S.) Inc. and O'Brien
Environmental Energy, Inc., is an independent power producer primarily in the
business of developing, owning and managing the operation of cogeneration
projects which produce electricity and thermal energy for sale under long-term
contracts with industrial and commercial users and public utilities. The Company
is currently focusing on natural gas-fired cogeneration projects with long-term
contracts for substantially all of the output of such projects including "inside
the fence" projects on the premises of the project's steam/energy hosts. The
Company's strategy is to develop, acquire and manage the operation of such
cogeneration projects and to provide U.S. industrial facilities and utilities
with reliable and competitively priced energy from the Company's power projects.

         CogenAmerica has substantial expertise in the development and
management of the operation of cogeneration power projects. The Company's
current project portfolio consists of: (i) the Parlin Project; (ii) the Newark
Project; (iii) the Morris Project; (iv) the Pryor Project; (v) an 83% interest
in the PWD Project; and (vi) a one-third interest in the Grays Ferry Project.
All of the Company's cogeneration projects commenced commercial operation in the
1990s.

         When still known as O'Brien, the Company emerged from bankruptcy on
April 30, 1996, under the Plan approved by the Bankruptcy Court. O'Brien had
filed a voluntary petition for reorganization under Chapter 11 of the United
States Bankruptcy Code on September 28, 1994. In connection with the
consummation of the Plan, all of the shares of O'Brien Class A and Class B
Common Stock were canceled and replaced by a new issue of common stock, par
value $.01 per share. At that time the Company changed its name to NRG
Generating (U.S.) Inc. In addition, NRG Energy advanced approximately $71,200
under loan agreements with the Company and purchased approximately 41.86% of the
Common Stock for aggregate consideration of approximately $21,200. NRG Energy
also purchased certain subsidiaries of the Company for $7,500 and funded a cash
distribution to the O'Brien stockholders aggregating $7,500. NRG Energy's
financial backing of the Plan enabled the Company to provide for full and
immediate payment of all undisputed pre-petition claims as well as a provision
for post-petition interest. In addition, pursuant to the Plan, NRG Energy and
the Company entered into a Co-Investment 



                                       5
<PAGE>


Agreement, pursuant to which NRG Energy has agreed to offer to the Company
ownership interests in certain power projects which are initially developed by
NRG Energy or with respect to which NRG Energy has entered into a binding
acquisition agreement with a third party. See "Business -- Project Development
- -- Co-Investment Agreement with NRG Energy."

         The Company was incorporated in Florida in 1981 and subsequently merged
with a Delaware corporation in 1984. Prior to the merger, the Company was part
of a group of several affiliated companies which had served the power generation
market since 1915.

         The following chart summarizes certain information concerning each of
the Company's projects. See "Business -- Products and Services -- Energy Segment
- -- Parlin Project," "-- Newark Project," "-- Morris Project," "--Pryor Project,"
"-- PWD Project" and "-- Grays Ferry Project."

PRODUCTS AND SERVICES

         During fiscal 1998, the Company operated principally in two industry
segments: (i) energy -- the development, ownership and operation of cogeneration
projects and standby/peak shaving projects through wholly-owned subsidiaries and
limited liability companies; and (ii) equipment sales, rental and service -- the
sale and rental of power generating, cogenerating and standby/peak shaving
equipment and associated services. The Company has determined and previously
announced that its equipment sales, rental and service business is no longer a
part of its strategic plan. On November 5, 1998 the Company sold OES, a
wholly-owned subsidiary of the Company, in a stock transaction to an unrelated
third party. The Company is currently pursuing alternatives for the disposition
of PUMA, which comprises the remaining operations of the equipment sales, rental
and service segment. See Note 18 of the Notes to the Consolidated Financial
Statements for financial information with respect to industry segments.

     ENERGY SEGMENT

         OVERVIEW. Cogeneration involves the sequential production of two or
more forms of usable energy (E.G., electricity and thermal energy) using a
single fuel source, thereby substantially increasing fuel efficiency. The key
elements to the successful development and operation of a cogeneration project
are permit applications, contracts for sales of electricity and thermal energy,
contracts or arrangements for fuel supply and project operation, and project
financing and construction. The Company attempts to design and develop its
projects so that they qualify for the benefits of PURPA, which exempts QFs from
rate, financial and similar utility regulation and requires public utilities to
purchase power generated by these projects. Electricity may be sold to utilities
and end users of electrical power, including large industrial facilities, and
possibly to power marketers. Thermal energy from cogeneration plants may be sold
to commercial enterprises and other institutions. Large industrial users of
thermal energy include plants in the chemical processing, petroleum refining,
food processing, pharmaceutical and paper industries. The Company owns equity
interests in five operating cogeneration projects discussed below -- the Parlin,
Newark, Morris, Pryor and Grays Ferry Projects. Revenues from these projects
collectively accounted for 65.0%, 60.2%, 49.1% and 63.9% of the Company's total
revenues for 1998, 1997, the 1996 transition period and 1996, respectively.


                                       7
<PAGE>

         The Company owns an 83% equity interest in one operating standby/peak
shaving generator project, the PWD Project. Revenues from this project accounted
for 5.6%, 6.5%, 5.2% and 4.2% of the Company's total revenues for 1998, 1997,
the 1996 transition period and 1996, respectively. Large electrical demand
customers use a standby/peak shaving project's power generation equipment as a
back-up source of electricity. The availability of an alternative energy source
allows these customers to benefit from discounted interruptible energy tariffs
from their primary electricity provider. Standby/peak shaving generators
typically are required to be available and be capable of providing a specified
amount of electricity during peak periods within a limited time.

         Each of these projects is currently producing revenues under long-term
contracts. Business interruption insurance and performance guarantees from the
third-party operators have been obtained for the cogeneration projects in
connection with the financing of such projects. These arrangements are
negotiated and closed prior to commencement of project operations. Taken as a
whole, these arrangements reduce the risks associated with any past and future
equipment problems or unscheduled plant shutdowns. For example, in the event of
an unscheduled outage, the Company and any other project owners generally are
entitled, pursuant to its business interruption insurance policy, to the net
profit which it is prevented from earning from the particular project, including
all charges and expenses which continue during the period of interruption, less
the applicable deductible amounts.

         NEWARK PROJECT. The Newark Project is a 58 MW gas-fired combined cycle
cogeneration project located in Newark, New Jersey that utilizes one General
Electric Frame 6B combustion turbine with an air inlet chiller system. The
Newark Project commenced operation in November 1990. CogenAmerica Newark, a
wholly-owned subsidiary of the Company, owns all of the Newark Project. As a QF,
the Newark Project sells up to 58 MW of electric power to JCP&L and provides up
to 75,000 pounds per hour of steam to Newark Boxboard. In September 1998 the
Company completed an upgrade of the electrical and steam production systems and
increased the electrical production capacity from 52 MW to 58 MW. The upgrade
added a mechanical chiller unit to cool inlet air to the combustion turbine
which increased the capacity to supply steam and electricity to Newark Boxboard.
The Newark Project accounted for approximately $17,541 and $17,319 in revenues,
representing approximately 23.7% and 26.7% of the Company's consolidated
revenues, during the years ended December 31, 1998 and 1997, respectively.

         PARLIN PROJECT. The Parlin Project is a 122 MW gas-fired combined cycle
cogeneration project located in Parlin, New Jersey that utilizes two General
Electric Frame 6B turbine generators. The Parlin Project commenced operation in
June 1991. CogenAmerica Parlin, a wholly-owned subsidiary of the Company, owns
all of the Parlin Project. As an EWG, the Parlin Project sells up to 114 MW of
electric power to JCP&L and provides up to 150,000 pounds per hour of steam to
DuPont. In addition, the Parlin Project sells up to 9 MW of power to NPI, a
wholly-owned subsidiary of NRG Energy, which power NPI resells to DuPont. The
Parlin Project accounted for approximately $21,527 and $21,685 in revenues,
representing approximately 29.1% and 33.5% of the Company's consolidated
revenues, during the years ended December 31, 1998 and 1997, respectively.

         MORRIS PROJECT. The Morris Project is a 117 MW gas-fired cogeneration
project located near Morris, Illinois that utilizes three General Electric Frame
6 combustion turbines and three heat recovery steam generators. The Morris
Project commenced operation in November 1998. CogenAmerica Morris LLC, a
wholly-owned subsidiary of CogenAmerica Funding, currently 


                                       8
<PAGE>

owns all of the Morris Project. The Morris Project sells as a QF up to an
average of 78 MW of electric power and up to 720,000 pounds per hour of steam to
Equistar. The Morris Project designed redundancy into the energy production
capability of the facility in order to meet Equistar's steam and electric
demand, and as a result the Morris Project expects that it will be able to make
periodic sales of energy to other customers on a merchant basis.

         In the Morris ESA, Equistar was granted an option to purchase up to 10%
of the Morris Project. In February 1998, Equistar gave notice of its intention
to purchase a 5% membership interest in the Morris Project.
The parties have not finalized an acquisition agreement.

         The Morris Project accounted for approximately $5,779 in
revenues, representing approximately 7.8% of the Company's consolidated
revenues, during the year ended December 31, 1998. The Morris Project commenced
commercial operations in November 1998. The Morris facility experienced two
unscheduled outages in January 1999 which resulted in service and business
interruptions to Equistar. CogenAmerica, Equistar and NRG Energy as provider of
construction management services and operation and maintenance services, are
currently investigating the matter and are examining their respective rights and
obligations with respect to each other and with respect to potentially
responsible third parties, including insurers. CogenAmerica's investigation and
discussions with Equistar are continuing. The company does not believe that
there will be a material adverse impact on the financial statements, however, no
assurance can be given as the ultimate outcome of this matter.

         GRAYS FERRY PROJECT. The Grays Ferry Project is a 150 MW dual-fueled
(natural gas and fuel oil) combined-cycle cogeneration plant located in
Philadelphia, Pennsylvania that commenced operation in January 1998. The Grays
Ferry Partnership owns 100% of the Grays Ferry Project. The Grays Ferry
Partnership is a general partnership that is one-third owned by each of
CogenAmerica Schuylkill, a wholly-owned subsidiary of the Company,
Trigen-Schuylkill Cogeneration Inc., an affiliate of Trigen, and Adwin
(Schuylkill) Cogeneration, Inc., an affiliate of PECO. As a QF, the Grays Ferry
Project sells all of its electric power to PECO and provides all of its steam to
TPEC.

         In March 1998, PECO declared that the Grays Ferry PPAs were ineffective
and ceased paying in full for electricity. The Grays Ferry Partnership
instituted a lawsuit against PECO and obtained a preliminary injunction
requiring PECO to make electricity payments in full while the litigation
proceeds. The Grays Ferry Partnership recorded revenue of approximately $78,126
from PECO in 1998. PECO claims it was not obligated to pay approximately $34,500
of such revenue. The Company has recorded $4,758 of equity in earnings of
affiliates representing its pro rata share of the Grays Ferry Partnership's net
income for the year ended December 31, 1998. On March 9, 1999 the court issued
an order for partial summary judgment in favor of the Grays Ferry Partnership,
ruling that PECO's attempted termination of the Grays Ferry PPA was improper.
See "Business - Risk Factors -- Grays Ferry Litigation/Default" and "Item 3. --
Legal Proceedings."

         PRYOR PROJECT. The Pryor Project is a 110 MW combined cycle facility
located in Pryor, Oklahoma. Oklahoma Loan Acquisition Corporation ("OLAC"), a
wholly-owned subsidiary of the Company, owns 100% of the Pryor Project. The
Company acquired all of the capital stock of OLAC on October 9, 1998 from MCPC,
which was 50% owned by NRG Energy and 50% owned by Decker Energy, International
and associated entities. The facility sells power to OG&E on a dispatchable
basis and steam to a number of industrial users including Georgia-Pacific. The
facility also sells electricity to PSO when not dispatched by OG&E. Subsequent
to the 


                                       9
<PAGE>


acquisition, the Pryor Project accounted for approximately $3,235 in revenues,
representing approximately 4.4% of the Company's consolidated revenues, during
the year ended December 31, 1998.

         PWD PROJECT. The PWD Project comprises two standby peak shaving 
facilities (each of which has a number of gas and diesel generator sets) 
located at the PWD's Northeast and Southwest waste water treatment plants in 
Philadelphia, Pennsylvania. Each facility has a capacity of approximately 11 
MW for an aggregate capacity of 22 MW. The PWD Project's Northeast unit 
commenced operation in May 1993, and its Southwest unit commenced operation 
in September 1993. OPCI sells the short-start-time capacity of the two units 
to the Authority, and the Authority has the right to demand energy from the 
PWD Project at any time on thirty minutes' notice. The biogas portion of each 
unit (approximately 1 MW in each case) operates as a QF, but the standby 
generators do not. The PWD Project accounted for approximately $4,134 and 
$4,206 in revenues, representing approximately 5.6% and 6.5% of the Company's 
consolidated revenues, during the years ended December 31, 1998 and 1997, 
respectively.

         The Company owns substantially all of the assets constituting the PWD
Project except for its principal project agreements, which are held by OPCI. All
of the common stock of OPCI is held by the Company and all of the preferred
stock of OPCI is held by an unrelated third party. The terms of the preferred
stock entitle the preferred stockholder to receive dividends equal to 17% of
OPCI's earnings (as determined in accordance with the terms of the preferred
stock).

     EQUIPMENT SALES, RENTAL AND SERVICE SEGMENT

         In 1998, the Company operated its equipment sales, rental and service
segment principally through two subsidiaries: OES, which, until it was sold in
November 1998, served the United States market; and NRG Generating Limited, a
holding company for a number of subsidiaries that operate in the United Kingdom
under the common name of PUMA. Revenues from this segment accounted for 29.4%,
33.3%, 41.8% and 28.2% of the Company's consolidated revenues for 1998, 1997,
the 1996 transition period and 1996, respectively.

         The Company has determined and previously announced that its equipment
sales, rental and services business is not a part of its strategic plan.
Accordingly, on November 5, 1998 the Company sold OES to an unrelated third
party for $2,000. The Company is currently pursuing several avenues for the
disposition of PUMA, which is not expected to have a material adverse effect on
the Company's financial position or results of operations.

         PUMA designs and assembles diesel and natural gas fueled power
generation systems ranging in size from 5 kilowatts to 5 MW. These products are
engineered and sold for use in prime power base load applications as well as for
standby or main failure emergency situations. Major markets for these products
include commercial buildings, governmental institutions such as schools,
hospitals and public facilities, industrial manufacturing or production plants,
shipyards, the entertainment industry and offshore drilling operations. PUMA
also designs and manufactures custom electrical control and distribution
subsystems. These include medium voltage cubicle switchboards, main distribution
systems, control instrumentation panels and packaged substations. This equipment
receives and distributes power through a building, ship or other self-contained
structure. PUMA exports many of its products primarily through established
distributors and dealers in local areas for delivery to markets such as Europe,
the Far East, including Hong Kong and mainland China, together with the Middle
East and South America. The revenues from the Company's operations in the U.K.
are attributable solely to the equipment sales and services segment of the
Company's business. The revenues from such operations accounted for 63% of 


                                       10
<PAGE>


that particular segment's revenue in 1998. See Note 18 of the Notes to the
audited Consolidated Financial Statements for financial information with respect
to the Company's domestic and foreign operations.

PROJECT DEVELOPMENT ACTIVITIES

   GENERAL

         The Company, its subsidiaries and affiliates develop, own and manage
the operation of power projects which produce electricity and/or thermal energy
for sale to industrial and commercial users and to public utilities. The Company
follows a disciplined and focused approach to its development efforts.
Specifically, the Company focuses its development activities on both the
acquisition of operating cogeneration and power generation facilities and the
development of greenfield inside-the-fence cogeneration projects.

         In pursuing new opportunities, the Company plans to adhere to the
following stringent selection criteria:

         PROFITABILITY. The Company does not plan to pursue new greenfield
projects or acquisitions merely for the sake of growth, but rather seeks to grow
with the addition of profitable projects.

         MID-SIZE PROJECTS. The Company plans to focus on middle market size
projects.

         DOMESTIC FOCUS. The Company intends to seek opportunities for the
foreseeable future exclusively in the U.S., thus avoiding any exposure to
foreign political and currency exchange rate risk.

         MANAGEMENT INPUT AND CONTROL. The Company seeks to have sole ownership
of future projects. However, to the extent that a potential partner offers
complementary skills and resources, the Company will consider partnering with
such a firm, provided that the Company has significant managerial and strategic
input. The Company does not plan to pursue purely passive minority stakes.

         LONG-TERM CONTRACTS. The Company seeks to develop projects that include
medium to long-term off-take contracts with creditworthy commercial or
industrial offtakers.

         FUEL RISK. The Company attempts to structure off-take contracts for
new projects to avoid the risk of fluctuations in fuel prices.

         In addition to its internal project development efforts, the Company is
party to the Co-Investment Agreement with NRG Energy. Pursuant to this
agreement, NRG Energy has agreed to offer to the Company the opportunity to
acquire ownership interests in certain power projects initially developed by NRG
Energy or with respect to which NRG Energy has entered into a binding
acquisition agreement with a third party. The Company continues to believe this
Agreement will not serve as the primary source of future project development
activities. However, NRG Energy continues to express its commitment to support
the business development activities of the Company. See "Business -- Project
Development Activities -- Co-Investment Agreement with NRG Energy."


                                       11
<PAGE>


    POTENTIAL PROJECTS

         The Company from time to time identifies and considers potential
opportunities to develop additional projects as well as to acquire projects in
operation or under development that are owned by third parties.

         As a project developer, the Company is responsible for the evaluation,
design, installation and operation of a project. The Company also assumes the
responsibility for evaluating project alternatives, obtaining financing,
insurance and all necessary licenses, permits and certifications, conducting
contract negotiations with offtakers, and arranging turnkey construction. In
connection with obtaining financing, the Company may negotiate for credit
support facilities with equipment suppliers, turnkey construction firms and
financial institutions.

         The Company anticipates that in the ordinary course of its business it
will investigate and/or pursue opportunities with respect to various potential
projects which will not be completed. Moreover, in certain instances the Company
may not generate any revenue from such projects and may not be able to recover
its investment in such projects, each of which could have a material adverse
effect on the Company.

    CO-INVESTMENT AGREEMENT WITH NRG ENERGY

         Pursuant to the Co-Investment Agreement, NRG Energy has agreed to offer
to the Company ownership interests in certain power projects which were
initially developed by NRG Energy or with respect to which NRG Energy has
entered into a binding acquisition agreement with a third party. If any eligible
project reaches certain contract milestones (which include the execution of a
binding PPA and fuel supply agreement and the completion of a feasibility and
engineering study) by April 30, 2003, NRG Energy has agreed to offer to sell to
the Company all of NRG Energy's ownership interest in such project. Eligible
projects include, with certain exceptions and exclusions, proposed or existing
electric power plants within the U.S. which NRG Energy initially develops or in
which NRG Energy proposes to acquire an ownership interest. NRG Energy is
obligated under the Co-Investment Agreement to offer to the Company, during the
three-year period ending on April 30, 1999, projects with an aggregate equity
value of at least $60,000 or a minimum of 150 net MW. As of the date hereof,
ownership interests in projects with an aggregate of more than 240 net MW have
been offered under the Co-Investment Agreement, including the 117 MW Morris
Project and the 110 MW Pryor Project.

         Among the exclusions from the Co-Investment Agreement are (i) any
ownership interest in a project which is below a level that would cause the
project (or its owners) to be in violation of the relevant PPA or applicable
state or federal law upon the generation of electricity for sale by such
project, (ii) any indirect ownership interest held by NRG Energy in an eligible
project arising from NRG Energy's direct or indirect ownership of equity
interests in the Company, (iii) any ownership interest in a facility below 25 MW
in capacity, and (iv) any ownership interest that is retained in order to later
be sold in an "exempt transaction." Exempt transactions include (i) any sale or
disposition of all or a portion of an ownership interest that is consummated as
a result of a foreclosure or conveyance in lieu of foreclosure of liens or
security interests (other than by NRG Energy) encumbering the eligible project
or such ownership interest, (ii) any sale or disposition of an ownership
interest to a third party that is or will become a participant in the eligible
project (such as a local or industry investor, a financial institution or a fuel
or equipment supplier), provided that the obligation to sell the interest is
incidental to the provision of services or the contribution of assets to the
eligible project and is created prior to the execution and 


                                       12
<PAGE>

delivery of a binding PPA and fuel supply agreement and the completion of an
engineering and feasibility study with respect to the project, and (iii) any
sale or disposition of an ownership interest to another person as part of a
larger transaction involving the sale of all or substantially all of the assets
of NRG Energy or the sale of an equity interest in NRG Energy, provided that the
person acquiring the ownership interest agrees to be bound by the Co-Investment
Agreement with respect to such ownership interest (if such ownership interest
has not previously been offered for sale to CogenAmerica pursuant to the
Co-Investment Agreement). In January 1998, the Company initiated an arbitration
proceeding pursuant to the terms of the Co-Investment Agreement to resolve a
dispute with NRG Energy concerning the rights and obligations of the Company and
NRG Energy with respect to the Pryor Project. The arbitration proceeding was
resolved in favor of the Company and the Company closed on its acquisition of
the project on October 9, 1998.

         NRG Energy has agreed to finance the Company's purchase of ownership
interests that may be offered pursuant to its Co-Investment Agreement at
commercially competitive terms to the extent funds are unavailable to the
Company on comparable terms from other sources. The Co-Investment Agreement
requires any such financing to be recourse to the Company and secured by a lien
on the ownership interest acquired. The Company is required to repay such
financing from the net proceeds of any offerings of equity or debt securities of
the Company (when market conditions permit such offerings to be made on
favorable terms) after taking into account the working capital and other cash
requirements of the Company, as determined by its Board of Directors.

REGULATION OF THE COMPANY'S PROJECTS

         In connection with the development and operation of its projects, the
Company is significantly affected by federal, state and local energy laws and
regulations.

   SIGNIFICANCE OF QF STATUS

         With the exception of the Parlin Project and part of the PWD Project,
all of the Company's existing electric generating facilities are QFs. Under
PURPA, QFs receive certain regulatory and economic benefits. Specifically, the
owners of QFs generally receive exemption from the application of PUHCA, rate
and other utility regulation under the Federal Power Act, and state laws
concerning the rates and the financial and organizational regulation of electric
utilities. In addition, PURPA obligates utilities to purchase power offered by
QFs at an individual utility's "incremental cost of alternative electric
energy," which is sometimes referred to as the "avoided cost standard" and which
is defined as the cost that the utility avoids by not generating the power
itself or purchasing it from another source.

         In order to maintain QF status, a generating project must meet certain
technological criteria. QFs are required to generate sequentially electricity
and thermal energy (generally in the form of steam) under standards prescribed
by the FERC. As part of this requirement, every QF is required under FERC
regulations to meet certain standards on a calendar year basis relating to the
facility's overall thermal efficiency (i.e., conversion of the energy content of
fuel into useful electricity and steam) and relative production of electricity
versus steam. These standards are referred to collectively as the "operating and
efficiency standards."

         QFs that are qualifying small power production facilities are required
to produce a certain amount of their electric power using biomass, waste,
renewable resources or geothermal resources as their primary energy source and
are generally subject to size restrictions.


                                       13
<PAGE>


         In addition to the technological requirements for QF status, under FERC
regulations no more than 50% of the attributable equity interest in a QF may be
owned by an electric utility.

         The failure of a QF to meet any of the requirements for QF status can
result in material adverse consequences to the owner of the facility. Under FERC
precedent, for any calendar year in which a QF fails to meet the applicable
requirements for QF status, the owner of the facility is required to refund to
any utility purchasing power from the facility the difference between the
contracted rate for sales of power and the utility's hourly incremental cost of
electric energy during the year in question. In addition, contracts for the
purchase of power from QFs (including some power purchase contracts for the
Company's facilities) frequently provide for termination of the contract or
other adverse consequences in the event that the facility is not continuously
maintained as a QF. Finally, in the event that a QF is permanently unable to
meet the criteria for QF status it risks the loss of all of its regulatory
exemptions, most notably the exemption from PUHCA. See "Business -- Risk Factors
- -- Loss of QF Status" and "-- Risks Associated with Becoming a Holding Company
under PUHCA."

   SIGNIFICANCE OF EWG STATUS

         One alternative to QF status is for the owner of a generating project
to become an EWG. PUHCA, as amended by the Energy Policy Act of 1992, defines an
EWG as a person determined by the FERC to be "engaged directly (or indirectly)
and exclusively in the business of ...selling electric energy at wholesale" and
meetinG certain other criteria. An EWG is completely exempt from PUHCA, and all
companies are free to acquire EWGs without restrictions. Moreover EWGs are
permitted to own QFs. The Company has elected to obtain EWG status for its
Parlin Project.

         Because the Parlin Project is not a QF, CogenAmerica Parlin is not
exempt from wholesale rate regulation and has therefore filed rates with the
FERC as a public utility under the Federal Power Act. In the event that
CogenAmerica Parlin lost EWG status, the Company would suffer material adverse
consequences under PUHCA. See "Business -- Risk Factors -- Risks Associated with
Becoming a Holding Company under PUHCA."

   SPECIAL STATUS OF PWD PROJECT

         The PWD Project consists of two identical generation facilities located
at separate but proximate sites, each facility consisting of approximately 1 MW
of biogas-fired generating equipment and 10 MW of natural gas-fired generating
equipment. The owner of the principal project agreements of the PWD Project,
OPCI, sells all power produced by the biogas-fired units to a retail customer,
the Authority. In addition, OPCI is obligated to provide the Authority with 20
MW of standby power from the natural gas fired generating units upon thirty
minutes' notice.

         The biogas-fired generating units collectively constitute a QF.
However, the standby natural gas-fired generation units included within the PWD
Project are not part of the PWD QF and therefore do not carry with them any of
the regulatory exemptions that otherwise accompany QF status. Nevertheless, the
Company believes that the ownership of the natural gas-fired generating units by
OPCI does not make it an "electric utility company" under PUHCA, by virtue of 17
CFR 250 of the SEC's regulations. See "Business -- Risk Factors -- Risks
Associated witH Becoming a Holding Company under PUHCA."

<PAGE>


ENVIRONMENTAL LAW AND REGULATIONS

         In addition to the regulations described above, the Company and its
projects are subject to a number of comprehensive environmental laws and
regulations, affecting both present and future operations. The laws and
regulations applicable to the Company primarily relate to the discharge of
emissions into the water and air, but can also include wetlands preservation,
waste disposal and noise abatement. Frequently, these laws and regulations
require a lengthy and complex process of obtaining licenses, permits and
approvals from federal, state and local agencies as well as ongoing reporting
and compliance obligations. Compliance may require modification of a project
which may increase its cost, extend its completion date or otherwise adversely
affect a project before or after its completion. Additional or modified
licenses, permits and approvals may be required for any physical or operational
changes to the Company's facilities. For some conditions, environmental laws
also may impose cleanup or other remediation obligations. In many instances,
state laws impose requirements on the Company that are similar to, and in some
cases more stringent than, the requirements under federal law. Noncompliance
with environmental laws and regulations can result in the imposition of civil or
criminal fines or penalties. The current environmental requirements under which
the Company's projects operate are subject to amendment, and the Company cannot
predict what effect compliance with such amendments may have on the Company's
business or operations.

         As discussed below, the Company believes its facilities are in
substantial compliance with applicable environmental requirements. To date,
compliance with these environmental regulations has not had a material effect on
the Company's earnings and has not required the Company to expend significant
capital.

         In the future, the environmental requirements likely to have the
greatest impact on the Company's business and operations are the air quality
emission limitations under the Clean Air Act. As originally enacted, the Clean
Air Act set guidelines for emission standards for major pollutants (e.g., sulfur
dioxide and NOx) from newly constructed stationary sources. The Clean Air Act
provides for the regulation, largely through state implementation of federal
requirements, of emissions of regulated substances from certain facilities and
operations, including an obligation to obtain preconstruction and operating
permits for sources of certain air emissions. Each state in which the Company's
plants are located implements the requirements of the Clean Air Act through its
own state air pollution control statute and implementing regulations. For
example, the requirements of the Clean Air Act are implemented in New Jersey
through the New Jersey State Air Pollution Act, in Pennsylvania through the
Pennsylvania Air Pollution Control Act, in Illinois through the Illinois
Environmental Protection Act, and in Oklahoma through the Oklahoma Clean Air
Act. Each of the states implements these requirements through regulations
promulgated by the EPA and the respective state agencies.

         In November 1990, significant amendments to the Clean Air Act were
adopted by Congress. The 1990 Amendments attempt to reduce emissions from
existing sources, particularly previously exempted older power plants. Although
the EPA is still implementing the requirements mandated by the 1990 Amendments,
the Company believes that air quality regulations in the U.S. will become even
more stringent. Currently, the Company believes that all of the Company's
operating plants are in compliance in all material respects with applicable
federal and state performance standards under the Clean Air Act, the 1990
Amendments and the state statutory and regulatory air quality requirements of
the states in which they are located.

         The 1990 Amendments require the EPA to establish technology-based
emission standards 


                                       15
<PAGE>

for hazardous air pollutants. "Electric utility steam generating units" greater
than 25 MW have been excluded from regulation pending completion of an EPA study
of hazardous air pollutant emissions from these units to determine whether such
regulation is "appropriate and necessary." The final report, issued in February
1998, concluded that regulation of hazardous air pollutant emissions from those
units is not necessary with a few possible exceptions. The EPA has decided to
conduct further studies of certain utility emissions and will determine at a
later date whether regulation of those emissions is appropriate. The EPA plans
to issue hazardous air pollutant regulations for combustion sources not included
within the scope of the EPA's electric utility study by November 2000. Depending
on whether they are finalized, these regulations may require the Company to
install additional emission control technology.

         With the exception of the Pryor Project in Oklahoma, each of the
Company's projects are located in an area which does not attain the National
Ambient Air Quality Standard for ozone. Accordingly, these projects will be
subject to stringent preconstruction review requirements if they undertake
"major modifications" to their facilities and they may face more stringent
emissions limitations on NOx, a precursor to ozone formation, than facilities
that are located in areas attaining the ozone standard. Other requirements apply
to "major modifications" to the Pryor Project, as this project is located in an
area which meets the National Ambient Air Quality Standards.

         Additionally, the EPA and several states are in the process of
developing more stringent emission limitations to control ground-level ozone
across the entire eastern U.S. that may ultimately affect all of the Company's
projects. In November 1997, the EPA proposed a rule that would require 22 states
in the eastern U.S., including Illinois, New Jersey and Pennsylvania, to make
substantial reductions in NOx emissions. If finalized as proposed, this rule
potentially could result in the adoption of new NOx emission standards by the
affected states. If more stringent NOx standards are adopted by states in which
the Company has facilities, the Company could be required to install additional
NOx emission control technology at such facilities. In addition, the EPA
recently lowered the current National Ambient Air Quality Standards for
ground-level ozone and particulate matter, and these new standards will be
implemented by the states over the next several years. To comply with the new
standards, additional control technology requirements may be required at the
Company's existing facilities. The Company does not believe that the effect of
any such additional requirements, if implemented, would have a material adverse
effect on its financial condition or operations.

         Section 112(r) of the Clean Air Act requires facilities in certain
industries, including electricity generation, to prepare and submit a Risk
Management Plan to the EPA which examines certain release scenarios and provides
for the public review of this information. The New Jersey Toxic Catastrophe
Prevention Act ("TCPA") requires owners of facilities that use an
"extraordinarily hazardous substance" to prepare a comprehensive risk management
plan covering their use of such substances. The Company's Parlin and Newark
Project facilities in New Jersey are subject to these requirements because
anhydrous ammonia is used in the air pollution control systems operating at the
facility. The TCPA requirements are more stringent than the federal
requirements. Although Illinois does not currently have a state program similar
to the TCPA applicable to the electricity generation industry, the state is
currently developing a program with similar requirements. Pennsylvania does not
currently have a similar state program requiring risk management plans for
electricity generating units. The Company believes that it is in material
compliance with the Clean Air Act and TCPA requirements concerning risk
management programs.


                                       16

         In addition to the regulations described above, the 1990 Amendments
established the North East Ozone Transport Region, which required northeastern
states, including New Jersey and Pennsylvania, to work together to determine
whether to adopt more stringent controls on the pollutants that contribute to
the formation of low-level ozone (i.e., volatile organic compounds and NOx).
Pursuant to a September 27, 1994 Memorandum of Understanding between the member
states of the North East Ozone Transport Region, New Jersey and Pennsylvania
have each proposed regulations to implement a region-wide budget for NOx
emissions. While some of the Company's operating plants will be subject to this
new rule (as presently drafted), and thus subject to stricter emission
limitations, the Company believes that the new rules will not have a material
impact on its ability to maintain its present level of operations.

         The Federal Clean Water Act (the "Clean Water Act"), the New Jersey
Water Pollution Control Act (the "Water Pollution Control Act"), the
Pennsylvania Clean Streams Law ("the Clean Streams Law"), the Illinois
Environmental Protection Act ("the Illinois Environmental Protection Act"), and
other water quality laws and regulations in other states establish rules
regulating the discharge of pollutants into surface and ground waters.
Typically, these water quality laws establish requirements for municipally-owned
sewage treatment plants, including pretreatment requirements for industrial
users of those plants. Each local municipal sewage authority has established
regulations governing connections to and discharges into its sewer system and
treatment plants. In accordance with these regulations, the Company is required
to obtain permits for the discharge of its wastewater and storm water runoff.
The Company believes that it is in substantial compliance with applicable
discharge requirements under the Clean Water Act, the Water Pollution Control
Act, the Clean Streams Law, the Illinois Environmental Protection Act, and other
State water quality regulations.

         The Resource Conservation and Recovery Act ("RCRA") regulates the
generation, treatment, storage, handling, transportation and disposal of solid
and hazardous wastes. The Company generates certain non-hazardous and hazardous
wastes that are subject to the requirements of RCRA and similar state statutes.
The Company believes that it is in substantial compliance with both the RCRA and
the similar state statutes.

         The Comprehensive Environmental Response, Compensation and Liability
Act of 1980, as amended ("CERCLA" or "Superfund"), requires cleanup of sites
from which there has been a release or threatened release of hazardous
substances. CERCLA authorizes the EPA and certain other parties to take any
necessary response action at Superfund sites, including ordering potentially
responsible parties ("PRPs") that are liable for the release to take or pay for
such actions. PRPs are broadly defined under CERCLA to include past and present
owners and operators of, as well as generators of wastes sent to, a site.

         In addition, the New Jersey Spill Act ("Spill Act"), the Pennsylvania
Hazardous Site Cleanup Act ("Site Cleanup Act"), and the Illinois Environmental
Protection Act, and other state laws and regulations, like many other state
superfund laws, impose similar liability under state law for discharges of
hazardous substances (including petroleum products) and, under certain
circumstances, authorizes the collection of treble damages from a responsible
party. Similar to CERCLA, PRPs are broadly defined to include owners and
operators of the facility where the discharge occurred, the owners of the
hazardous substance that is discharged, or anyone who has caused or allowed the
discharge to occur. As of the present time, the Company is not subject to
liability for any Superfund or other state superfund matters. However, the
Company generates certain wastes, including hazardous wastes, and sends certain
of its wastes to third-party waste 


                                       17
<PAGE>

disposal sites. As a result, there can be no assurance that the Company will not
incur liability under CERCLA, the Spill Act, the Site Cleanup Act, the Illinois
Environmental Protection Act, or other state statutes in the future.

         State laws and regulations also requires facilities that store
significant quantities of petroleum products or other hazardous substances to
prepare detailed discharge prevention containment and countermeasure plans and
discharge cleanup and removal plans. The Company believes that it is in
substantial compliance with these requirements with respect to its plants.

COMPETITION

         Many organizations, including equipment manufacturers and subsidiaries
of utilities and contractors, as well as other organizations similar to the
Company, have entered the cogeneration market. Many of these organizations have
substantially greater resources than the Company. In addition, obtaining power
contracts with utilities has become more competitive with the increased use of
competitive bidding procedures and the movement towards deregulation of the
electricity energy market. This increased competition may make it more difficult
for the Company to secure future projects, may increase project development
costs and may reduce the Company's operating margins. In addition, increased
competition is leading to the development of a market for merchant plants.
Merchant plants are power generation facilities that sell all or a portion of
their electricity into the competitive market rather than pursuant to long-term
power sales agreements. The operation of a merchant plant is essentially
participation in a commodity market, which creates certain risk exposures,
including, among other things, underlying price volatility, credit risk and
variation in cash flows. Even though many of its potential competitors have
substantially greater resources than the Company, management believes that its
experience, particularly if combined with a strategic alliance with a third
party with regard to larger projects, will enable it to compete effectively.

PRINCIPAL CUSTOMER

         The Company derived 50%, 57%, 46% and 62% of its revenues in 1998,
1997, the 1996 transition period and 1996, respectively, from JCP&L as a result
of the operation of the Newark and Parlin facilities.

         Approximately 53% and 60% of the Company's revenues during 1998 and
1997, respectively, were derived from the operations of the Parlin and Newark
Projects. JCP&L buys substantially all of the power from these projects. For at
least the near-term, the Company will continue to be substantially dependent on
the operations of these projects. A material decrease in the results of
operations for such projects would likely have a material adverse effect on the
Company's results of operations and financial condition. The success of the
Company will continue to depend in part on its ability to diversify its project
portfolio. There can be no assurance that the Company will be successful in its
diversification efforts.

EMPLOYEES

         As of December 31, 1998, the Company had approximately 90 full-time
employees, including 33 in the energy business and approximately 57 in its
equipment, sales and services business.


                                       18

BACKLOG

         Total production backlog relating to the Company's equipment sales and
services business was $4,054 and $3,900 at December 31, 1998 and 1997,
respectively.

INTELLECTUAL PROPERTY

         The Company and its subsidiaries do not own any patents or trademarks,
but the Company uses the trade name "CogenAmerica." It has applied for federal
trademark registration of its full name and its logo (which includes this trade
name).

RISK FACTORS

     INFLUENCE BY NRG ENERGY

         NRG Energy owns approximately 45.2% of the Company's outstanding Common
Stock. Five of the Company's eight directors are executive officers of NRG
Energy. NRG Energy is a major domestic and international developer of
independent power projects. As a result, persons who simultaneously serve as
directors or executive officers of the Company and as directors or executive
officers of NRG Energy may be subject to conflicts of interest with respect to
business opportunities or other investments which may be of interest to both NRG
Energy and the Company. While the Company's Amended and Restated Articles of
Incorporation impose supermajority requirements in certain circumstances, and
while the Independent Directors Committee of the Board of Directors (the
"Independent Directors' Committee") has exclusive jurisdiction over the
Company's contractual relations and other material transactions with NRG Energy
(including under the Co-Investment Agreement), NRG Energy's share ownership may
permit it effectively to substantially influence the outcome of matters which
may be submitted to a vote of the shareholders, including the election of
directors of the Company (other than the members of the Independent Directors
Committee, who are nominated by the Independent Directors' Committee rather than
by the Board of Directors). NRG Energy also may exert significant influence over
the Company's business and affairs through its representation on the Board of
Directors and its other relationships with the Company, including the
Co-Investment Agreement. See "Business -- Project Development Activities --
Co-Investment Agreement with NRG Energy." A subsidiary of NRG Energy also serves
as the operator of the Company's Parlin and Newark Projects, and another
subsidiary of NRG Energy is serving as the operator of the Company's Morris
Project. A subsidiary of NRG Energy also purchases power from the Parlin Project
and sells such power to DuPont. NRG Energy, in its business relationships with
the Company and in its role as a shareholder of the Company, may have interests
which conflict with those of the Company and the other stockholders of the
Company under certain circumstances.

     SUBSTANTIAL LEVERAGE

         As of December 31, 1998, the Company had approximately $285,096 of
long-term debt, including approximately $219,683 of subsidiary-level
indebtedness. The Company may also incur additional indebtedness in the future.
Accordingly, the Company has significant debt service obligations. The extent of
the Company's leverage may have important consequences for the Company and its
shareholders, including, but not limited to, the following: (i) the ability of
the Company to obtain additional financing for acquisitions, working capital,
capital expenditures or other purposes, if necessary, may be impaired or such
financing may not be available on terms acceptable to the Company; (ii) a
substantial portion of the Company's cash flow will be used to 


                                       19
<PAGE>

pay the Company's interest expense and under certain conditions to repay
indebtedness, which will reduce the funds that would otherwise be available to
the Company for its operations and future business opportunities; (iii) a
substantial decrease in net operating cash flows or an increase in expenses of
the Company could make it difficult for the Company to meet its debt service
obligations and force it to modify its operations; (iv) the Company may be more
highly leveraged than its competitors, which may place it at a competitive
disadvantage; and (v) the Company's high degree of leverage may limit its
flexibility to react to changes in its operating environment or economic
conditions, making it more vulnerable to a downturn in its business or the
economy generally.

     ENERGY PRICE FLUCTUATIONS AND FUEL SUPPLY COSTS

         The Company's PPAs with utilities have typically contained, and may in
the future contain, price provisions which in part are linked to the utilities'
cost of generating electricity. In addition, the Company's fuel supply prices,
with respect to future projects, may be fixed in some cases or may be linked to
fluctuations in energy prices. These circumstances can result, and have
resulted, in volatility in gross margins and reduced operating income, either of
which could have a material adverse effect on the Company's financial position
or results of operations. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Results of Operations -- Comparison of
the year ended December 31, 1998, 1997 the 1996 TransitioN Period and 1996 --
Costs and Expenses."

     SEASONALITY

         The Company's quarterly operating results have varied in the past and
may vary significantly in the future depending on many factors, including among
others: unusual weather conditions in the areas served by the Company's
projects, routine or unanticipated maintenance that may require an outage and
general economic conditions. Further, the Company's operating results have been,
and are expected to continue to be, highly sensitive to seasonal variations. The
Company's operations have historically been seasonal in nature with a
disproportionate percentage of revenues and earnings recorded in the Company's
first and third quarters, the winter and summer seasons. Based upon all of the
foregoing factors, the Company believes that its revenues, expenses and
operating results are likely to vary significantly from quarter to quarter in
the future, that period-to-period comparisons of its results of operations may
not be meaningful and that, in any event, such comparisons should not be relied
upon as indications of future performance.

     PROJECT DEVELOPMENT AND CONSTRUCTION RISKS

         The projects that the Company develops are generally large and complex
and require months or years to complete. Among the principal objectives involved
in developing projects are the selection of a site, obtaining commitments from
others to purchase electrical power and steam, negotiating fuel supply
arrangements, obtaining environmental and other governmental permits and
approvals, and arranging project financing and turnkey construction. These
objectives are subject to a host of uncertainties which in many instances cannot
be anticipated. Moreover, these objectives often are achieved independently of
one another, and success in achieving one objective does not necessarily
increase the likelihood of achieving others. There can be no assurance that the
Company will be able to obtain satisfactory projects from its own development
efforts, under the Co-Investment Agreement or from other sources, and
satisfactory project agreements, construction contracts, necessary licenses and
permits or satisfactory financing commitments in respect of such projects, or
that any projects will ultimately be completed. The Company may from time to
time 


                                       20
<PAGE>

devote substantial resources to the pursuit of competitively bid projects that
it is not awarded or projects that ultimately prove to be undesirable
investments. If its development efforts are not successful, the Company may
abandon a project under development. At the time of abandonment, the Company
would expense all capitalized development costs incurred in connection with the
project and could incur additional losses associated with any related contingent
liabilities. Such losses could have a material adverse effect on the Company's
results of operations and financial position.

         The construction, expansion or refurbishment of a cogeneration facility
also involves many risks, including supply interruptions, work stoppages, labor
disputes, weather interferences, unforeseen engineering, environmental and
geological problems and unanticipated cost overruns and start-up problems,
including the breakdown or failure of equipment or processes and performance
below expected levels of output or efficiency. Such risks may result in reduced
revenues or increased expenses and may cause the Company to incur other
unrecovered costs. Moreover, most PPAs permit the purchaser to terminate the
agreement or impose penalties if the commercial operation of the project is not
achieved by a specified date. As a result, any material unremedied delay in, or
unsatisfactory completion of, construction of the Company's projects could have
a material adverse effect on the Company's business or financial condition.
Insurance is maintained to protect against certain of these construction and
start-up risks, warranties are generally obtained for limited periods relating
to the construction of a new plant and its equipment to varying degrees, and
contracts and equipment suppliers are obligated to meet certain performance
levels. Such insurance, warranties or performance guarantees may not be adequate
to cover lost revenues or increased expenses and, as a result, a project may be
unable to fund principal and interest payments under its financing obligations
(if any) and may operate at a loss. A default under such a financing obligation
could result in the Company losing its interest in any such new cogeneration
facility and could have other material adverse effects on the Company's
financial condition or results of operations. This could occur if, for example,
any such default were to result in defaults under other material contracts or
financing obligations of the Company.

     GENERAL OPERATING UNCERTAINTIES

         The operation of a power plant involves many risks, including the
breakdown or failure of power generation equipment, pipelines, transmission
lines or other equipment or processes, fuel interruption, and performance below
expected levels of output or efficiency. Moreover, new plants have no operating
history and may employ recently developed and technologically complex equipment.
Each facility may depend on a single or limited number of entities to purchase
electricity or thermal energy, to supply water, to supply fuel, to transport
fuel, to dispose of wastes or to transport or "wheel" electricity. The failure
of any such power purchaser, steam host, water or fuel supplier, fuel
transporter, wheeling utility or other relevant project participant to fulfill
its contractual obligations, or the occurrence of other unforeseen construction,
start-up or operating difficulties, could have a material adverse effect on the
profitability of the project and on the Company. The foregoing operating risks
may result in lost revenues or increased expenses, including higher maintenance
costs and penalties. Ultimately, the foregoing operating uncertainties can cause
a facility to be unable to perform its obligations under its power and steam
purchase agreements, triggering default provisions in financing agreements which
could render the project insolvent and which could have a material adverse
effect on the ability of the Company to service its debt.


                                       21
<PAGE>


     RISKS INVOLVED IN MAKING MINORITY INVESTMENTS IN PROJECTS

         The Company currently conducts its business primarily through direct
and indirect wholly-owned or majority-owned subsidiaries. However, one of the
Company's current project investments, the Grays Ferry Project, consists of a
minority ownership interest in a project entity, which is operated by one of the
Company's partners. Moreover, future investments in projects may also take the
form of minority interests. The Company's ability to control the development,
construction, acquisition or operation of such projects may be limited. The
Company may be dependent on its co-investors to construct and/or to operate such
projects. There can be no assurance that such co-investors will have the same
level of experience, technical expertise, human resources management and other
attributes as the Company. Any such co-investor may have conflicts of interests,
including those relating to its status as a provider of goods or services to, or
a purchaser of power or other services from, the project. The approval of its
co-investors also may be required for distributions of funds from projects to
the Company.

     DEPENDENCE ON CERTAIN CUSTOMERS AND PROJECTS

         All of the Company's energy segment earnings are derived from six
projects. The Company's projects (including projects in which it may make
minority investments) typically rely on a single customer or a few customers to
purchase all or substantially all of a facility's output, in each case under
long-term agreements that provide the support for any project debt used to
finance such facilities. The failure of any one customer to fulfill its
contractual obligations to a facility could have a material adverse effect on
such facility's financial results and on the Company. As a result, the financial
performance of such facilities is dependent on continued performance by
customers of their obligations under such long-term agreements. Regulatory
developments, including deregulation and industry restructuring activity, may
cause major customers to attempt to renegotiate contracts or otherwise fail to
perform their contractual obligations. In addition, major customers may attempt
to renegotiate contracts or otherwise fail to perform their contractual
obligations if changes in current economic conditions make the terms of such
contracts less favorable to such customers. The occurrence of one or more of
these events could adversely affect the Company's results of operations and
financial condition.

     COMPETITION

         Many organizations, including equipment manufacturers and subsidiaries
of utilities and contractors, as well as other organizations similar to the
Company, have entered the market for the development, ownership and operation of
cogeneration projects. Many of these companies have substantially greater
resources and/or access to the capital required to fund such activities than the
Company. In addition, obtaining power contracts with utilities has become more
competitive with the increased use of competitive bidding procedures and
short-term electric purchases through power marketers and the acceleration of
deregulation in the electric utility market. This increased competition may
adversely affect the Company's ability to secure future projects and
project-level financing, increase project development costs and reduce the
Company's operating margins and returns on any future project investments. Any
such developments could have a material adverse effect on the Company's results
of operations and financial condition. See "Business -- Competition."

     LOSS OF QF STATUS

         With the exception of the Parlin Project and part of the PWD Project,
all of the Company's 


                                       22
<PAGE>

existing electric generating facilities are QFs. In order to maintain QF status,
a generating project must meet certain technological criteria. QFs that are
qualifying cogeneration facilities are required to generate sequentially
electricity and thermal energy (generally in the form of steam) under standards
prescribed by the FERC. As part of this requirement, every QF is required under
FERC regulations to meet certain standards on a calendar year basis relating to
the facility's overall thermal efficiency (i.e., conversion of the energy
content of fuel into useful electricity and steam) and relative production of
electricity versus steam. Accordingly, it is critical for QFs to have steam
sales contracts that require the purchaser to accept amounts of steam which
allow the facility to meet the requisite operating and efficiency standards.
Cessations or material reductions in steam purchases from a cogeneration
facility carry the risk that the facility will fail to meet the FERC's operating
and efficiency standards, resulting in a loss of QF status. Similarly, for QFs a
critical factor in maintaining QF status is the use of enough biomass, waste,
renewable resources or geothermal resources (rather than supplementary fossil
fuels) to meet the requirements of the FERC's regulations concerning primary
energy source.

         The failure of a QF to meet any of the requirements for QF status can
result in material adverse consequences to the owner of the facility. Under
FERC, for any calendar year in which a QF fails to meet the applicable
requirements for QF status, the owner of the facility is required to refund to
any utility purchasing power from the facility the difference between the
contracted rate for sales of power and the utility's hourly incremental cost of
electric energy during the year in question. In addition, contracts for the
purchase of power from QFs (including some power purchase contracts for the
Company's facilities) frequently provide for termination of the contract or
other adverse consequences in the event that the facility is not continuously
maintained as a QF. Finally, in the event that a QF is permanently unable to
meet the criteria for QF status it risks the loss of all of its regulatory
exemptions, most notably the exemption from PUHCA, as discussed below. See
"Business -- Regulation of the Company's Projects -- Significance of QF Status."

     RISKS ASSOCIATED WITH BECOMING A HOLDING COMPANY UNDER PUHCA

         In the event that the Company becomes a "holding company" under PUHCA,
the Company would suffer material adverse consequences. The following situations
would cause the Company to become a holding company under PUHCA: (i) the loss of
QF status for one of the Company's generating projects, which would cause the
subsidiary owning the project to become an "electric utility company" under
PUHCA; (ii) the loss of EWG status for CogenAmerica Parlin, which would also
cause such subsidiary to become an electric utility company under PUHCA; and
(iii) the loss of OPCI's exemption under 17 CFR ss. 250.7(a) of the SEC's
regulations, which would result in OPCI becoming aN electric utility company
under PUHCA. See "Business -- Regulation of the Company's Projects --
Significance of QF Status," "-- Significance of EWG Status" and "-- Special
Status of PWD Project."

         One of the requirements under the FERC's regulations for determining QF
status of a project is that utility ownership be limited to 50% of the equity
interest in the project. Thus, because all of the QFs in which the Company has
an ownership interest are either: (i) more than 50% owned by the Company, or
(ii) partially owned by a utility whose ownership interest together with the
Company's interest exceeds 50%, if the Company became a holding company under
PUHCA the QF status of all of the Company's QF projects could automatically be
lost, at least temporarily. The loss of QF status for these projects could
trigger refund obligations and power sales contract terminations, as described
above, and ultimately could require portions of 


                                       23
<PAGE>

the projects to be divested in order for QF status to be regained. Other
consequences of the Company becoming a holding company under PUHCA are difficult
to predict but could ultimately include a requirement that the Company divest
itself completely of certain of its generating projects and a requirement that
NRG Energy, the owner of 45.2% of the Company's stock, divest itself of its
interest in the Company.

     RESTRUCTURING OF THE ELECTRIC UTILITY INDUSTRY

         The U.S. Congress is considering legislation to repeal PURPA entirely,
or at least to repeal the obligation of utilities to purchase from QFs
thereunder. There is support for grandfathering QF contracts if such legislation
is enacted, and also support for requiring utilities to conduct competitive
bidding for new electric generation if the PURPA purchase obligation is
eliminated. Under PURPA, QFs receive the benefit of exemptions from the Federal
Power Act, PUHCA and certain aspects of state utility regulation. In addition,
PURPA obligates utilities to purchase power offered by QFs at an individual
utility's "incremental cost of alternative electric energy," which is sometimes
referred to as the "avoided cost" standard and which is defined as the cost that
the utility avoids by not generating the power itself or purchasing it
elsewhere. All of the Company's projects other than the Parlin Project and a
part of the PWD Project are QFs. Since the Company benefits from PURPA, the
Company's business could experience a material adverse effect in the event of
the repeal of, or a significant change in, PURPA.

         Various bills have also proposed repeal of PUHCA. Repeal of PUHCA would
allow both independent power producers and vertically integrated utilities to
acquire retail utilities in the U.S. that are geographically widespread, as
opposed to the current requirements of PUHCA which, as interpreted by the SEC,
tend to require that retail electric systems owned by the same entity be capable
of either electric integration or to be operated in geographic proximity. With
the repeal of PURPA and PUHCA, competition for independent power generators from
vertically integrated utilities would likely increase. Any such repeal could
have a material adverse effect on the Company's financial position or results of
operations.

         While the Company does not believe that ongoing federal and state
restructuring efforts necessarily will have a material adverse effect on its
financial position or results of operations, the long term effect of any such
restructuring on the Company cannot be predicted at this time. See "Business --
Regulation of the Company's Projects."

     GRAYS FERRY LITIGATION/DEFAULT

         PECO, the electric power purchaser from the Grays Ferry Project, has
asserted that its PPAs with the Grays Ferry Partnership are not effective based
on an alleged denial of cost recovery by the Pennsylvania Public Utility
Commission. PECO claims that it is not obligated to pay the rates set forth in
the agreements. PECO has further taken the position that, in any event, its
total liability under each of the two PPAs is limited to $25,000 ($50,000 in
aggregate) by the terms of such agreements. The Company and the Grays Ferry
Partnership are in litigation with PECO over its obligations under such
agreements. After initially refusing to pay the rates set forth in the PPAs and
making payments for the electricity purchased from the Grays Ferry Project at
substantially lower rates, PECO has been ordered by the court in which the
litigation is pending to comply with the PPAs pending the outcome of the
litigation. Following the court order, PECO has resumed paying under protest the
full contract rates and, as of December 31, 1998, has paid all amounts then due
under the applicable PPAs. Through December 31, 1998, the Grays Ferry
Partnership has recorded revenue of approximately $78,100 of which $34,500
represents the amount which PECO 


                                       24
<PAGE>


claims it was not obligated to pay. For the year ended December 31, 1998, the
Company has recorded $4,758 of equity in earnings of affiliates representing its
pro rata share of the Grays Ferry Partnership's net income for such period. In
addition, the Company's investment in the Grays Ferry Partnership totaled
$17,603 on December 31, 1998. On March 9, 1999 the court issued an order for
partial summary judgment in favor of the Grays Ferry Partnership, ruling that
PECO's attempted termination of the Grays Ferry PPAs was improper.

         Due to PECO's actions the Grays Ferry Partnership defaulted in the
payment of certain interest due under its principal credit agreement, which
default has since been cured, and the Grays Ferry Partnership continues to be in
default under other provisions of such credit agreement. As a result of such
continuing default, the lenders under the credit agreement have the ability
generally to prevent the Grays Ferry Partnership from distributing or otherwise
disbursing cash held or generated by the Grays Ferry Project. These rights, if
exercised by the lenders, could prevent the Grays Ferry Partnership from meeting
its obligations to suppliers and others and from disbursing or otherwise
distributing cash to its partners during the pendency of the litigation. Any of
these actions by the Grays Ferry Partnership's lenders could materially disrupt
the Grays Ferry Partnership's relations with its suppliers and could have other
potentially material adverse effects on its operations and profitability and,
ultimately, on the Company's earnings and financial position. While the Grays
Ferry Partnership's lenders have allowed the partnership to meet its obligations
to suppliers, the partnership received a notice of default from the lenders on
June 22, 1998, for the failure to timely convert the loan used for construction
purposes to a term loan. This failure occurred due to the event of default
created by the alleged termination of the PPAs by PECO and due to the inability
of the Grays Ferry Partnership to declare either provisional or final acceptance
of the Grays Ferry Project due to the existence of certain unresolved issues
between the Grays Ferry Partnership and Westinghouse Electric Corporation
("Westinghouse") regarding completion and testing of the Grays Ferry Project.
These issues between the partnership and Westinghouse are the subject of an
ongoing arbitration proceeding. Until there is a satisfactory resolution of the
litigation with PECO, the lenders will not allow distributions for the payment
of subordinated fees, payments to the subordinated debt lender or equity
distributions to the partners. In lieu of making these payments, Grays Ferry
Partnership will be required to apply such amounts to the repayment of the loan.
During 1998, $18,700 was applied to the repayment of the loan. The Company
further expects that at the time the litigation is resolved the loan will be
restructured.

         The Company believes that if PECO's position ultimately is sustained,
the Grays Ferry Partnership would cease to be economically viable as currently
structured and the Company's earnings and financial position could be materially
adversely affected in various respects. Such effects could include, without
limitation, a material adjustment to the value of the Company's investment in
the Grays Ferry Project, the loss of future income and cash flows from the
project and other material costs which would not be recovered. See "Item 3.
- --Legal Proceedings."

     ENVIRONMENTAL LAW AND REGULATION

         The Company and its projects are subject to a number of comprehensive
environmental laws and regulations, affecting many aspects of its present and
future operations. The laws and regulations applicable to the Company primarily
involve the discharge of emissions into the water and air, but can also include
wetlands preservation, waste disposal and noise abatement. Frequently, these
laws and regulations require a lengthy and complex process of obtaining
licenses, permits and approvals from federal, state and local agencies as well
as ongoing reporting and 


                                       25
<PAGE>

compliance obligations. Compliance may require modification of a project which
may increase its costs, extend its completion date or otherwise adversely affect
a project before or after its completion. Additional or modified licenses,
permits and approvals may be required for any physical or operational changes to
the Company's facilities. For some conditions, environmental laws also may
impose cleanup or other remediation obligations. In many instances, state laws
impose requirements on the Company that are similar to, and in some cases more
stringent than, the requirements under federal law. Noncompliance with
environmental laws and regulations can result in the imposition of civil or
criminal fines or penalties. The current environmental requirements under which
the Company's projects operate are subject to amendment, and the Company cannot
predict what effect compliance with such amendments may have on the Company's
business or operations.

         In the future, the environmental requirements likely to have the
greatest impact on the Company's business and operations are air quality
emission limitations under the Clean Air Act. As originally enacted, the Clean
Air Act set guidelines for emission standards for major pollutants (e.g., sulfur
dioxide and nitrogen oxide ("NOx")) from newly constructed stationary sources.
The Clean Air Act provides for the regulation, largely through state
implementation of federal requirements, of emissions of regulated substances
from certain facilities and operations, including an obligation to obtain
preconstruction and operating permits for sources of certain air emissions. Each
state in which the Company plants are located implements the requirements of the
Clean Air Act through its own state air pollution control statute and
implementing regulations. In New Jersey, for example, the requirements of the
Clean Air Act are implemented through the New Jersey State Air Pollution Act. In
Pennsylvania, the requirements are implemented through the Pennsylvania Air
Pollution Control Act, in Illinois through the Illinois Environmental Protection
Act, and in Oklahoma through the Oklahoma Clean Air Act. Each of the states
implement these requirements through regulations promulgated by the U.S.
Environmental Protection Agency (the "EPA") and the respective state agencies.

         In November 1990, significant amendments to the Clean Air Act were
adopted by Congress (the "1990 Amendments"). The 1990 Amendments attempt to
reduce emissions from existing sources, particularly previously exempted older
power plants. Although the EPA is still implementing the requirements mandated
by the 1990 Amendments, the Company believes that air quality regulations in the
U.S. may become even more stringent.

         The 1990 Amendments require the EPA to establish technology-based
emission standards for hazardous air pollutants. "Electric utility steam
generating units" greater than 25 MW have been excluded from regulation pending
completion of an EPA study of hazardous air pollutant emissions from these units
to determine whether such regulation is "appropriate and necessary." The final
report, issued in February 1998, concluded that regulation of hazardous air
pollutant emissions from those units is not necessary with a few possible
exceptions. The EPA has decided to conduct further studies of certain utility
emissions and will determine at a later date whether regulation of those
emissions is appropriate. The EPA plans to issue hazardous air pollutant
regulations for combustion sources not included within the scope of the EPA's
electric utility study by November 2000. Depending on whether they are
finalized, these regulations may require the Company to install additional
emission control technology.

         The EPA and several states are in the process of developing more
stringent emission limitations to control ground-level ozone. In November 1997,
the EPA proposed a rule that would require 22 states in the Eastern U.S.,
including Illinois, New Jersey and Pennsylvania, to make 


                                       26
<PAGE>

substantial reductions in NOx emissions. If finalized as proposed, this rule
potentially could result in the adoption of new NOx emission standards by the
affected states. If more stringent NOx standards are adopted by states in which
the Company has facilities, the Company could be required to install additional
NOx emission control technology at such facilities. In addition, the EPA
recently lowered the current National Ambient Air Quality Standards for
ground-level ozone and particulate matter, and these new standards will be
implemented by the states over the next several years. To comply with the new
standards, additional control technology requirements may be required at the
Company's existing facilities.

         In addition to the above, the 1990 Amendments established the North
East Ozone Transport Region which required northeastern states, including New
Jersey and Pennsylvania, to work together to determine whether to adopt more
stringent controls on the pollutants that contribute to the formation of
low-level ozone (i.e., volatile organic compounds and oxides of nitrogen).
Pursuant to a September 27, 1994 Memorandum of Understanding between the member
states of the North East Ozone Transport Region, New Jersey and Pennsylvania
have each proposed regulations to implement a region-wide budget for nitrogen
oxide emissions.

     CAPITAL REQUIREMENTS

         The Company's business is capital intensive. The long-term growth of
the Company, which involves the development and acquisition of additional power
generation projects, will require the Company to seek substantial funds through
various forms of financing. There can be no assurance that the Company will be
able to arrange the financing needed for additional projects. Also, limitations
in the Company's credit agreements may limit its ability to finance future
projects on a recourse basis, thereby requiring the Company to finance such
future projects on a substantially nonrecourse basis, which may either be
unavailable, or available on terms which may not be acceptable to the Company.
In order to access capital on a substantially nonrecourse basis in the future,
the Company may have to make larger equity investments in, or provide more
financial support for, its subsidiaries and other project entities. The
Company's ability to arrange financing of additional projects and the costs of
such capital are dependent on numerous factors, including general economic and
capital market conditions, credit availability from banks and other financial
institutions, investor confidence in the Company, its partners and in the
independent power market, the success of current projects, the perceived quality
of new projects and applicable tax and securities laws. If the Company is unable
to secure such financing, or if the terms of such financing are not satisfactory
to the Company, its business could be materially adversely affected. See
"Business -- Project Development Activities."

     RECENT HISTORY OF LOSSES

         The Company filed a voluntary petition for reorganization under Chapter
11 of the U.S. Bankruptcy Code on September 28, 1994. Formerly known as O'Brien,
the Company emerged from bankruptcy on April 30, 1996, under the Plan approved
by the Bankruptcy Court. The Company reported net income of approximately
$8,002, $23,352 and $6,423 for the fiscal years ended December 31, 1998,
December 31, 1997 and the six months ended December 31, 1996, respectively.
However, due in part to costs associated with its bankruptcy proceeding, the
Company incurred losses of approximately $17,713 and $40,919 for the fiscal
years ended June 30, 1996, and June 30, 1995, respectively. These losses and the
Company's bankruptcy had a material adverse effect on the Company's liquidity
and financial position and may continue to adversely affect the Company's
liquidity and results of operations in future periods by, among other things,


                                       27
<PAGE>

rendering it more difficult for the Company to raise capital or otherwise to
conduct project development activities.

     RISKS ASSOCIATED WITH FOREIGN OPERATIONS

         The Company does not generate power outside of the U.S. Its foreign
operations consist of its equipment sales and rental operations based in the
U.K. which sell in various international markets and which are subject to the
risks inherent in doing business in foreign countries, including changes in
currency exchange rates, currency restrictions, changes in duties and quotas,
introduction of tariff or non-tarriff barriers, and economic, political and
regulatory changes. The Company currently does not engage in hedging
transactions. There can be no assurance that any of the factors described above
will not have a material adverse effect on the Company's business, operating
results and financial condition. See "Business -- Products and Services 
- -- Equipment Sales, Rentals and Services Segment."

     YEAR 2000

         The Company has implemented a Year 2000 compliance program designed to
ensure that the Company's computer systems and applications will function
properly beyond 1999. The Company believes that it has allocated adequate
resources for this purpose and expects its Year 2000 conversions to be completed
on a timely basis. In light of its compliance efforts, the Company does not
believe that the Year 2000 issue will materially adversely affect operations or
results of operations, and does not expect implementation to have a material
impact on the Company's financial statements. However, there can be no assurance
that the Company's systems will be Year 2000 compliant prior to December 31,
1999, or that the failure of any such system will not have a material adverse
effect on the Company's business, operating results and financial condition. In
addition, to the extent the Year 2000 problem has a material adverse effect on
the business, operations or financial condition of third parties with whom the
Company has material relationships, such as venders, suppliers and customers,
the Year 2000 problem could have a material adverse effect on the Company's
business, results of operations and financial condition.

this Report on Form 10-K, whether as a result of new information, future events
or otherwise.


ITEM 2.  PROPERTIES.

         The Company's corporate headquarters are located in suburban
Minneapolis, Minnesota. On June 4, 1998, the Company entered into a lease with
respect to approximately 6,745 square feet of space for its corporate
headquarters which continues until July 17, 2003.

         The headquarters for PUMA's executive offices and its principal
manufacturing facility (each of which serve the Company's equipment sales,
rentals and services segment) are located in Ash, Canterbury, Kent, United
Kingdom.

         The Newark, PWD, Parlin, Grays Ferry, Pryor and Morris project entities
(each of which is in the Company's energy segment) lease property for the sites
of its facilities from the commercial user of electric or thermal energy for a
nominal fee. The lease terms equal or exceed that of each respective electric or
thermal supply agreement. Management believes that these leased premises are
suitable and adequate for the Company's projects.


ITEM 3.           LEGAL PROCEEDINGS.

         The Company or a subsidiary is party to the following legal
proceedings:

1.    STEVENS, ET AL. V. O'BRIEN ENVIRONMENTAL ENERGY, INC., ET AL., United
      States District Court for the Eastern District of Pennsylvania, Civil
      Action No. 94-cv-4577, filed July 27, 1994. This action was filed by
      certain purchasers of the Class A Common Stock of the Company's
      predecessor, O'Brien Environmental Energy, Inc. ("O'Brien"), during the
      class period of O'Brien's bankruptcy. The plaintiffs alleged various
      violations of the Federal securities laws, claiming that certain material
      misrepresentations and nondisclosures concerning the Company's financial
      conditions and prospects allegedly caused the price of the Common Stock to
      be artificially inflated during the class period. The parties in this
      action have agreed on a proposed settlement, which was filed with the
      District Court for its approval on March 18, 1999. Management does not
      expect the outcome of this litigation to have a material adverse effect on
      the Company.

2.    BLACKMAN AND FRANTZ V. O'BRIEN, United States District Court, Eastern
      District of Pennsylvania, Civil Action No. 94-cv-5686, filed October 25,
      1995. This action was filed by purchasers of O'Brien debentures during the
      class period. The Plaintiffs objected to treatment of the class under the
      Plan. This matter has been consolidated with the Stevens class action case
      described in paragraph number 1 above. The parties in this action have
      agreed on a proposed settlement, and on February 11, 1999, filed the
      proposed settlement with the District Court for its approval. Management
      does not expect the outcome of this litigation to have a material adverse
      effect on the Company.

3.    IN RE: O'BRIEN ENVIRONMENTAL ENERGY, Case No. 94-26723, U.S. Bankruptcy
      Court for the District of New Jersey, filed September 29, 1994. Calpine
      Corporation ("Calpine"), an unsuccessful bidder for the acquisition of
      O'Brien in the bankruptcy case, filed an application for allowance of an
      administrative claim for approximately $4,500 in break-up fees and
      expenses in the bankruptcy case. The Bankruptcy Court denied the
      application 


                                       29
<PAGE>

      in full, by order dated November 27, 1996. Calpine filed an appeal from
      the Bankruptcy Court's order denying its application. On May 29, 1998 the
      United States District Court for the District of New Jersey upheld the
      Bankruptcy Court's order. Calpine filed an appeal with the United States
      Third Circuit Court of Appeals on June 26, 1998. The appeal has been
      briefed, but oral arguments have not yet occurred. Management does not
      expect the outcome of its bankruptcy case to have a material adverse
      effect on the Company.

4.    GRAYS FERRY COGENERATION PARTNERSHIP, TRIGEN-SCHUYLKILL COGENERATION,
      INC., NRGG (SCHUYLKILL) COGENERATION INC. AND TRIGEN-PHILADELPHIA ENERGY
      CORP. V. PECO ENERGY COMPANY, ADWIN (SCHUYLKILL) COGENERATION, INC. AND
      THE PENNSYLVANIA PUBLIC UTILITY COMMISSION, Court of Common Pleas
      Philadelphia County, April Term 1998, No. 544, filed April 9, 1998. This
      action arose out of PECO's notification to the Grays Ferry Partnership
      that PECO believes its PPAs with the Grays Ferry Partnership relating to
      the Grays Ferry Project are no longer effective and PECO's refusal to pay
      the electricity rates set forth in the agreement based on its allegations
      that the Pennsylvania Public Utility Commission has denied cost recovery
      of the PPAs in retail electric rates. The Grays Ferry Partnership's
      complaint against PECO asserts claims which include breach of contract,
      fraud, breach of implied covenant of good faith, conversion, breach of
      fiduciary duties and tortious interference with contract. The Plaintiffs
      are seeking to enjoin PECO from terminating the PPAs and to compel PECO to
      pay the rates set forth therein. The Plaintiffs also are seeking actual
      and punitive damages and attorneys' fees and costs. On April 22, 1998, the
      court allowed the Grays Ferry Partnership to file an amended complaint to
      discontinue the suit against the Pennsylvania Public Utility Commission
      without prejudice. On May 5, 1998, the Grays Ferry Partnership obtained a
      preliminary injunction pending the outcome of the litigation enjoining
      PECO from terminating the PPAs and ordering PECO to comply with the terms
      of the PPAs. The Court of Common Pleas in Philadelphia also ordered PECO
      to abide by all of the terms and conditions of the PPAs and pay the rates
      set forth in the agreements. The Plaintiffs were required to post a bond
      in the amount of $50 in connection with the preliminary injunction. On May
      8, 1998, PECO filed a notice of appeal and a motion to stay the
      preliminary injunction order. On May 13, 1998, the Grays Ferry Partnership
      filed an emergency petition for contempt to compel PECO to pay the amounts
      due and owing under the PPAs. On May 20, 1998, the Court of Common Pleas
      granted the motion for civil contempt and ordered PECO to pay $50 for each
      day that PECO failed to comply with the court's order. The power
      purchaser, in response to the preliminary injunction, has made all past
      due payments and continues to make payments to the Grays Ferry Partnership
      according to the terms of the PPAs, in each case under protest. On August
      10, 1998, Chase filed an unopposed petition to intervene as a co-plaintiff
      in the litigation, which was entered on August 26, 1998. Chase's
      complaint, filed on September 4, 1998, asserted claims against PECO in
      connection with Chase's roles as lender and agent of other lenders under
      the Grays Ferry Project financing credit agreement. On March 9, 1999 the
      Court of Common Pleas issued an order for partial summary judgment in
      favor of the Grays Ferry Partnership, ruling that PECO's attempted
      termination of the Grays Ferry PPAs was improper. Trial is set for March
      29, 1999 to determine damages owed to the Grays Ferry Partnership, as well
      as to decide the remaining claims such as fraud, conversion, breach of the
      implied covenant of good faith and breach of fiduciary duties.


                                       30
<PAGE>


         The Company is subject from time to time to various other claims that
arise in the normal course of business, and management believes that the outcome
of any such matters as currently may be pending (either individually or in the
aggregate) will not have a material adverse effect on the business or financial
condition of the Company.


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

        As previously reported by the registrant, on September 14, 1998, NRG
Energy sent a letter to David H. Peterson, the Company's Chairman, requesting
that he call a special meeting of the Company's stockholders to consider the
removal of Robert T. Sherman, Jr. from the Company's Board of Directors. On such
date NRG Energy also filed preliminary solicitation materials with the SEC
pursuant to Section 14(a) of the Exchange Act, as amended, relating to a
proposed solicitation of proxies and consents from the Company's stockholders to
remove Mr. Sherman from the Company's Board (the "Proxy Solicitation"). On
October 8, 1998, NRG Energy filed definitive solicitation materials with the SEC
relating to the Proxy Solicitation.

         On October 26, 1998, NRG Energy delivered to the Company's registered
agent consents of the holders of more than 50% of the Company's outstanding
Common Stock in favor of Mr. Sherman's removal from the Company's Board of
Directors. The following persons continued to serve as directors of the Company
immediately following the delivery of the consents: David H. Peterson, Julie A.
Jorgensen, Lawrence I. Littman, Craig A. Mataczynski, Spyros S. Skouras, Jr.,
Charles J. Thayer and Ronald J. Will. At a Board of Directors meeting on October
27, 1998, by the affirmative vote of a majority of such directors, Michael
O'Sullivan was appointed to fill the vacancy created by the removal of Mr.
Sherman from the Board.

         At a Special Meeting of the Company's stockholders held on November 12,
1998, the stockholders approved the removal of Mr. Sherman as a director of
the Company, with the holders of 5,314,119 shares, or 77.73% of the outstanding
shares, voting in favor of such removal; the holders of 85,626 shares, or 1.25%
of the outstanding shares, voting against; and 9,139 abstentions. Continuing as
directors were Mr. Peterson, Ms. Jorgensen, Mr. Littman, Mr. Mataczynski, Mr.
Skouras, Mr. Thayer and Mr. Will. On the same day, the Company's Board of
Directors also confirmed the appointment of Michael O'Sullivan to fill the
vacancy on the Board of Directors created by the removal of Mr. Sherman.

         As of March 2, 1999, the Company had approximately 465 holders of
record of its Common Stock, not including beneficial owners whose shares are
held by banks, brokers and nominees.

         The Company did not pay any cash dividends during fiscal 1998 or 1997.
The Company presently intends to retain all earnings for the operation and
expansion of its business and does not anticipate paying cash dividends on its
Common Stock in the foreseeable future. Any future determination as to the
payment of dividends on the common stock will depend upon future earnings,
results of operations, capital requirements, the financial condition of the
Company and any other factors the Board of Directors of the Company may
consider. Moreover, as a holding company, the Company's ability to pay any
dividends in the future will depend largely on the ability of its operating
subsidiaries and project entities to pay cash dividends or other cash
distributions, which dividends or other cash distributions may be materially
limited by the terms of credit agreements or other material contracts to which
such operating subsidiaries or project entities may be parties.

         Two of the Company's principal operating subsidiaries, CogenAmerica
Newark and CogenAmerica Parlin, are parties to a Credit Agreement which
prohibits the payment of dividends by such subsidiaries to the Company, provided
that such dividend payments may be made out of funds available after the payment
of various costs and expenses set forth in the 


                                       32
<PAGE>


Credit Agreement (including, without limitation, operating costs, various debt
service payments and the funding of various accounts required to be maintained
pursuant to the Credit Agreement) if certain conditions set forth in the Credit
Agreement are satisfied, including, without limitation, the maintenance of a
debt service coverage ratio set forth in the Credit Agreement, the absence of
any default or event of default under the Credit Agreement, and the satisfaction
of certain conditions relating to the composition of the Board of Directors of
the Company.

         Morris LLC (the owner of the Morris Project) is party to a Construction
and Term Loan Agreement which prohibits the payment of distributions or the
return of capital to Morris LLC's members or the authorization to make any other
distribution, payment or delivery of property or cash to its members as such, or
redeem, retire, purchase or otherwise acquire any membership interests, units or
other equity interests of Morris LLC, or any options or rights thereto, or the
setting aside of funds for any of such purposes, except upon the satisfaction of
certain conditions which include (i) the acceptance and commercial operation of
the facility and conversion of the project's construction loan to term loans,
(ii) the absence of any default or event of default under various financing and
project documents, and the absence of the possibility that default will occur as
a result of such disbursement, (iii) the full prior funding of various accounts
required to be maintained by Morris LLC under the Construction and Term Loan
Agreement, and (iv) the maintenance of a required debt service coverage ratio.
The Company and CogenAmerica Funding also are parties to a Supplemental Loan
Agreement with NRG Energy which prohibits CogenAmerica Funding (which owns 100%
of the membership interests of Morris LLC) from paying any distributions or
dividends unless, among other things, the principal and interest then
outstanding does not exceed a prescribed maximum amount and is not projected to
exceed the maximum amount prescribed for the next two interest and principal
payment dates.

         The Company is the borrower under the MeesPierson Credit Agreement,
which prohibits the payment of dividends by the Company without prior written
consent unless the Company provides not less than 30 days prior to the proposed
date of payment of such dividend a letter of credit (in the form and upon the
terms provided in the MeesPierson Credit Agreement) and a certificate signed by
the chief financial officer of the Company that, after giving effect to such
dividend payment, no default or event of default (as defined in therein) would
occur or reasonably be anticipated to occur, and/or be continuing.

         The Grays Ferry Partnership (the owner of the Grays Ferry Project) is
party to a credit agreement, dated March 1, 1996 with Chase which prohibits the
Grays Ferry Partnership from making distributions unless i) the loan under the
agreement has converted to a term loan, ii) a specified debt service coverage
ratio is met, iii) no event of default has occurred and is continuing, and iv)
the distribution would not trigger an event of default. In addition, due to the
ongoing litigation between the Grays Ferry Partnership and PECO, Chase will not
allow any distributions to partners pursuant to Chase's rights under such credit
agreement. See Item 3. "Legal Proceedings."

         CogenAmerica and CogenAmerica Pryor are parties to a loan agreement,
dated October 9, 1998, with NRG Energy as lender, which prohibits the payment of
distributions unless i) CogenAmerica Pryor has sufficient unencumbered funds to
cover two payments of a specified interest payment obligation, ii) no event of
default has occurred and is continuing, and iii) after giving effect to the
proposed distribution, no event of default would occur or reasonably be
anticipated to occur and/or be continuing.

GENERAL

         CogenAmerica is an independent power producer pursuing
"inside-the-fence" cogeneration projects in the U.S. The Company is engaged
primarily in the business of developing, owning and managing the operation of
cogeneration projects which produce electricity and thermal energy for sale
under long-term contracts with industrial and commercial users and public
utilities. The Company is currently focusing on natural gas-fired cogeneration
projects with long-term contracts for substantially all of the output of such
projects. The Company's strategy is to develop, acquire and manage the operation
of such cogeneration projects and to provide U.S. industrial facilities and
utilities with reliable and competitively priced energy from its power projects.

         CogenAmerica has substantial expertise in the development and operation
of power projects. The Company's current project portfolio consists of:

(i)   a 122 MW cogeneration facility in Parlin, New Jersey, which began
      commercial operation in June 1991 and is owned through its wholly-owned
      subsidiary, CogenAmerica Parlin;

(ii)  a 58 MW cogeneration facility in Newark, New Jersey, which began
      commercial operation in November 1990 and is owned through its
      wholly-owned subsidiary, CogenAmerica Newark;

(iii) a 117 MW cogeneration facility in Morris, Illinois, which began commercial
      operation in November 1998 and is owned through its wholly-owned
      subsidiary, CogenAmerica Morris. See "Business --Products and Services --
      Energy Segment -- Morris Project";

(iv)  a 110 MW cogeneration facility in Pryor, Oklahoma, which had been in
      commercial operation prior to acquisition by the Company in October 1998,
      and is owned through the Company's wholly-owned subsidiary, Oklahoma Loan
      Acquisition Corporation;

(v)   two standby/peak shaving facilities with an aggregate capacity of 22 MW in
      Philadelphia, Pennsylvania, which began commercial operation in September
      1993, the principal project agreements of which are held by O'Brien
      (Philadelphia) Cogeneration, Inc., an 83%-owned subsidiary of the Company;
      and

(vi)  a one-third partnership interest in a 150 MW cogeneration facility located
      at Grays Ferry in Philadelphia, Pennsylvania, which began operation in
      January 1998.


                                       35
<PAGE>


         Each of the projects is currently producing revenues under long-term
power sales agreements that expire at various times. See the chart under
"Business -- General" which summarizes certain contractual arrangements and
other information concerning each of the Company's power projects.

         Energy and capacity payment rates are generally negotiated during the
development phase of a cogeneration project and are finalized prior to securing
project financing and the start of a plant's commercial operation. Pricing
provisions of each of the Company's project power sales agreements contain
unique features. As a result, different rates exist for each plant and customer
pursuant to the applicable power sales agreement.

         However, in general, revenues for each of the Company's cogeneration
projects consist of two components: energy payments and capacity payments.
Energy payments are based on the power plant's actual net electrical output,
expressed in kilowatt-hours of energy, purchased by the customer. Capacity
payments are based on the net electrical output the power plant is capable of
producing (or portion thereof) and which the customer has contracted to have
available for purchase. Energy payments are made for each kilowatt-hour of
energy delivered, while capacity payments, under certain circumstances, are made
whether or not any electricity is actually delivered.

         The projects' energy and capacity payments are generally based on
scheduled prices and/or base prices subject to periodic indexing mechanisms, as
specified in the power sales agreements. In general terms, energy and capacity
payments are intended to recover the variable and fixed costs of operating the
plant, respectively, plus a return.

         A power plant may be characterized as one or more of the following: a
"base-load" facility, a "dispatchable" facility, a combination
"base-load/dispatchable" facility or a "merchant" facility. Such
characterization depends upon the manner in which the plant will be used and the
requirements of the related power sales agreement(s). A "base-load" facility
generally means that the plant is operated continuously to produce a fixed
amount of energy and capacity for one or more customers. A "dispatchable"
facility generally means that the customer(s) purchased the right to a fixed
amount of available capacity, which must be produced if and when requested by
the customer(s). A combination "base-load/dispatchable" facility is a plant that
operates in both modes, with a portion of the plant's capacity designated as
base-load and the remainder available for dispatch. A "merchant" facility
generally refers to a plant that operates and sells its output to various
customers at prevailing market prices rather than pursuant to a long-term power
sales agreement.

         Under a power sales agreement with JCP&L extending into 2011,
CogenAmerica Parlin has committed 114 MW of the Parlin facility's generating
capacity to JCP&L, of which 41 MW are committed as base capacity and 73 MW as
dispatchable capacity. JCP&L must purchase energy from the base capacity
whenever such energy is available from the Parlin facility. Energy from the
dispatchable capacity is purchased by JCP&L only when requested (dispatched) by
JCP&L.

         The Parlin PPA provides for curtailment by JCP&L under such typical
conditions as emergencies, inspection and maintenance. In addition, JCP&L may
also reduce base capacity during periods of low load on the PJM by up to 600
hours in any calendar year, of which 400 may be during on-peak periods, but only
when all PJM member utilities are required to reduce generation to minimum
levels and PJM has requested JCP&L to reduce or interrupt external 


                                       36
<PAGE>


generation purchases. During 1998, JCP&L's curtailment was ten hours. The Parlin
PPA also provides for an annual average heat rate adjustment that will increase
or decrease JCP&L's payments to CogenAmerica Parlin, depending upon whether the
average heat rate of the Parlin Project is below or above average 9,500 Btu per
kWh (higher heating value). The actual adjustment is calculated by applying a
ratio based on this differential to a fuel cost calculation. For the year ended
December 31, 1998 this heat rate adjustment was $92.

         CogenAmerica Newark has a power sales agreement with JCP&L extending
through 2015 whereby it has committed to sell all of the Newark facility's
generating capacity to JCP&L, up to a maximum of 58 MW per hour. The Newark
Project is effectively a base-load unit and JCP&L must purchase the energy
whenever such energy is available from the Newark facility.

         Under the terms of the Newark PPA, JCP&L, in its sole discretion, is
allowed to curtail production at the facility for 700 hours per year provided
that the duration of each curtailment is a minimum of six hours and all
curtailments occur only during Saturdays, Sundays and Holidays. Since contract
inception in 1996, JCP&L has fully utilized this curtailment option annually and
the Company expects JCP&L will continue to do so in future years. JCP&L may also
disconnect from CogenAmerica Newark for emergencies, inspections and maintenance
for up to 400 hours per year if all PJM member utilities are required to reduce
generation to minimum levels and JCP&L has been requested by PJM to reduce or
interrupt external generation purchases. During 1998, JCP&L's curtailment for
these purposes was nine hours. The Newark PPA provides for an annual average
heat rate adjustment that will increase or decrease JCP&L's payments to
CogenAmerica Newark depending upon whether the average heat rate of the Newark
Project is above or below 9,750 Btu per kWh (higher heating value). The actual
adjustment is calculated by applying a ratio based upon this differential to a
fuel cost calculation. For the year ended December 31, 1998 this heat rate
adjustment reduced CogenAmerica Newark revenues by $684.

         Morris LLC has an ESA with Equistar through 2023 to provide base-load
power and steam. Equistar has agreed to purchase the entire requirements of
Equistar's plant (subject to certain exceptions) for electricity up to the full
electric output of two of the three combustion turbines at the Morris Project.
In addition, the Morris Project has an arrangement with the local utility to
provide standby power. Each combustion turbine at the Morris facility has a
nominal rating of 39 MW. The Morris Project designed redundancy into the energy
production capability of the facility in order to meet Equistar's demand. The
cost of installing and maintaining the reserve capacity was taken into account
when the energy services agreement was negotiated.

         CogenAmerica Morris is permitted to arrange for the sale to third
parties of interruptible capacity and/or energy from the third turbine and to
the extent available, any excess power from the two turbines required to supply
Equistar with its actual requirements. CogenAmerica Morris is in the process of
contracting with a third-party power marketer for the sale of this excess
capacity/energy.

         CogenAmerica Pryor has a power sales agreement with OG&E through 2008
to provide 110 MW of dispatchable capacity, with a maximum dispatch of 1,500
hours per year. The facility also sells electricity to PSO when not dispatched
by OG&E. The Pryor Project purchases natural gas from Dynegy and Aquila. Under
the terms of the agreement with PSO, the pricing of energy sales is indexed to a
market fuel rate. Under terms of the agreement with OG&E, energy sales are 
linked to the average cost of fuel.

         The power sales agreements for the Parlin, Newark, and Morris projects
are structured to avoid or minimize the impact on the Company's revenues from
fluctuations in fuel costs. Since the power sales agreements were amended in
April 1996, JCP&L is responsible for the supply and transportation of natural
gas required to operate the Parlin and Newark plants. Thus, revenues from the
Parlin and Newark plants exclude any amounts attributable to recovery of fuel
costs. Prior to the contract amendments, Parlin and Newark cost of revenues
included fuel and related costs and contract provisions for delayed recovery of
such costs in revenues caused variability in the projects' gross profit.

         Under the terms of the Morris ESA with Equistar, Equistar is the fuel
manager and all of the costs of supplying the fuel are effectively a
pass-through to Equistar. As a result, although fuel costs are included in the
Morris Project revenues and costs of revenues, the Company has minimized any
impact on gross profit from fluctuations in the price of natural gas purchases
and supply for the Morris Project.

         The Grays Ferry Project has a gas sales agreement with Aquila providing
for the purchase of natural gas to meet the power plant's requirements. For the
period from commercial operations in January 1998 until the end of the year
2000, the partnership has purchased a natural gas collar with a cap in order to
limit the volatility of natural gas purchases. Beginning in 2001, the price for
natural gas supplied by Aquila is indexed to a market electricity rate.

         During 1998, the Company also sold and rented power generation
equipment and provided related services in the U.S. and international markets
under the names OES and PUMA. As previously announced, the Company has
determined that its equipment sales, rental and service segment, which accounted
for $21,780, $21,594, $16,669 and $27,239 of revenues in 1998, 1997, the 1996
transition period and 1996, respectively, is no longer a part of its strategic
plan. Accordingly, on November 5, 1998 the Company sold OES, a wholly-owned
subsidiary of the Company, in a stock transaction to an unrelated third party
for $2,000. The Company is currently pursuing alternatives for the disposition
of its remaining equipment sales, rental and service business operated by PUMA.
The Company expects that the disposition of PUMA will not have a material
adverse effect on the Company's results of operations or financial condition.
Although OES was sold in 1998, the equipment sales, rental and service segment
has not been reported as a discontinued operation in the financial statements
because specific plans regarding the timing and manner of ultimate disposition
of PUMA are still under consideration.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

         REVENUES

         Energy revenues for 1998 of $52,216 increased from revenues of $43,210
for 1997. Energy revenues primarily reflect billings associated with the Parlin,
Newark, Morris and Pryor Projects and the Company's PWD Project. The increase in
energy revenues was primarily attributable to the acquisition of the Pryor
Project in October 1998, and commencement of Morris operations in November 1998.
Energy revenues in 1997 were negatively impacted by a routine, scheduled major
maintenance outage at the Newark Project in the second quarter of 1997.

</TABLE>


         Equipment sales and services revenues for 1998 of $19,342 decreased
from revenues of $19,415 for 1997. The decrease was attributable to the sale of
OES in November 1998. OES accounted for revenues of $5,625 and $6,115 in 1998
and 1997, respectively.

         Rental revenues for 1998 of $2,438 increased from revenues of $2,179
for 1997. The increases were due primarily to higher sales volume due to ice
storms in the northeastern U.S. and Canada. OES rental revenues were $2,391 and
$2,179 in 1998 and 1997, respectively.

         COSTS AND EXPENSES

         Cost of energy revenues for 1998 of $23,462 increased from $14,841 for
1997. The increase was primarily the result of commencement of Morris
operations, the Pryor acquisition and depreciation associated with equipment
capitalized at the Parlin and Newark facilities in 1998.

         Cost of equipment sales and services for 1998 of $16,929 decreased
from $17,037 for 1997. The decrease was primarily due to the sale of OES.

         Cost of rental revenues for 1998 of $1,954 increased from $1,817 for
1997. The increases were primarily due to increased sales volume due to ice
storms in the northeastern U.S. and Canada.

         Gross profit for 1998 of $31,651 increased from $31,109 for 1997. The
increase is primarily attributable to expansion of the Newark Project's rated
capacity from 52 MW to 58 MW and the addition of the Morris and Pryor
operations. The gross profit margin in 1998 was 42.8% as compared to 48.0% in
1997. This decrease was due primarily to the addition of the Morris and Pryor
Projects which have lower operating margins than the Newark and Parlin Projects.
It is expected that competition will continue to put pressure on these margins
in the future as new projects are added.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

         Selling, general and administrative expenses ("SG&A") for 1998 of
$9,415 decreased from $9,479 in 1997. The decrease is primarily due to lower
insurance costs, offset by higher legal expenses.


                                       39
<PAGE>


         INTEREST AND OTHER INCOME

         Interest and other income for 1998 of $1,715 increased from $1,205 for
1997. The increase is primarily attributable to a gain on the sale of OES.

         EQUITY IN EARNINGS OF AFFILIATES

         Equity in earnings of affiliates for 1998 was $4,784 compared to $105
for 1997. The increase was attributable to earnings from the Grays Ferry
Project, which commenced operations in January 1998. The earnings of the Grays
Ferry Project reflect the contract price of electricity under the terms of the
PPAs. The electric power purchaser has asserted that such PPAs are not effective
and that the power purchaser is not obligated to pay the rates set forth in the
agreements. The Company and the Grays Ferry Partnership are in litigation with
the power purchaser over that issue. For additional information see "Item 3. --
Legal Proceedings."

         INTEREST AND DEBT EXPENSE

         Interest and debt expense for 1998 of $15,855 increased from $14,768
for 1997. The increase is primarily attributable to debt issued to acquire the
Pryor Project, borrowings under the Supplemental Loan Agreement for the Morris
Project, and higher interest rates due to default rate interest.

         INCOME TAXES

         During the 1997 fourth quarter, the Company reduced the valuation
allowance established for tax benefits attributable to net operating loss
carryforwards and other deferred tax assets, resulting in recognition of most
remaining operating loss carryforwards in 1997 fourth quarter earnings.
Consequently, beginning with the 1998 first quarter, income taxes are generally
charged against pre-tax earnings without any reduction for operating loss
carryforwards that continue to be utilized in reducing income taxes currently
payable. Prior to the 1997 fourth quarter, net operating loss carryforwards were
recognized each period as a reduction of income tax expense based on pre-tax
income.

         The higher income tax expense in 1998 was due to the above-mentioned
reduction in the valuation allowance in 1997.

         NET INCOME AND EARNINGS PER SHARE

         Net income for 1998 was $8,002, or diluted earnings per share of $1.15,
compared to net income of $23,352 for 1997, or diluted earnings per share of
$3.48. Net income and earnings per share for 1998 were lower than the prior year
primarily due to the combined effects of the increase in income tax expense as a
result of the income tax benefit recognized in 1997, earnings from the Grays
Ferry Project which commenced operations in January 1998 and the one-time asset
impairment charge recorded in 1997.

 COMPARISON OF 1997, THE 1996 TRANSITION PERIOD AND 1996

         REVENUES

         Energy revenues for 1997, the 1996 transition period and 1996 were
$43,210, $21,669 and $66,623, respectively. Energy revenues primarily reflect
billings associated with the Parlin, Newark and PWD Projects.

         The revenues at the Parlin and Newark Projects have been affected by
the terms of their PPAs, which were renegotiated effective April 30, 1996 to
make JCP&L responsible for supplying the natural gas at no cost to the projects.
Previously, revenues from the Parlin and Newark Projects had reflected the
impact of unit fuel cost fluctuations on the energy rate calculation under the
Parlin and Newark PPAs. The increase in energy revenues for 1997 as compared to
the 1996 transition period was primarily due to only six months of revenues
reported in the 1996 transition period. The decrease in energy revenues for the
1996 transition period as compared to 1996 was primarily due to only six months
of revenues reported in the 1996 transition period and to the amended PPAs
affecting both the Parlin and Newark Projects.

         Parlin's 1996 revenues were negatively impacted by a voluntary
curtailment of electric output during the first and second quarters in order to
maintain the correct ratio of thermal to electric production after DuPont, the
steam host, significantly decreased its steam demand by moving a business
segment overseas. In addition, Parlin's 1996 revenues were affected by a
decrease in the energy rate under the previous PPA, which rate was adjusted
quarterly based on, in part, the average cost of fuel over the preceding year.

         Equipment sales and service revenues for 1997, the 1996 transition
period and 1996 were $19,415, $15,607 and $25,344, respectively, which
principally reflect the operations of OES, PUMA and American Hydrotherm
Corporation ("American Hydrotherm"). American Hydrotherm was sold in December
1996. Revenues increased for 1997 as compared to the 1996 transition period
primarily due to only six months of revenues reported in the 1996 transition
period and due to higher sales volumes. Revenues decreased for the 1996
transition period as compared to 1996 primarily due to only six months of
revenues reported in the 1996 transition period, offset in part by the inclusion
of nine months of revenues in the period from the operations of PUMA. PUMA
changed its fiscal year end from March 31 to a calendar year end effective on
December 31, 1996.

         OES equipment sales and service revenues for 1997, the 1996 transition
period and 1996 were $6,115, $1,575 and $5,232, respectively.

         Rental revenues for 1997, for the 1996 transition period and 1996 were
$2,179, $1,062 and $1,895, respectively. The fluctuations were primarily due to
only six months of revenues reported in the 1996 transition period.

         There were no development fees and other revenues for 1997. Development
fees and other revenues for the 1996 transition period and 1996 were $1,578 and
$2,685, respectively.

<PAGE>


Revenues decreased for the 1996 transition period as compared to 1996 primarily
due to only six months of revenues reported in the 1996 transition period.

         COSTS AND EXPENSES

         Cost of energy revenues for 1997, the 1996 transition period and 1996
were $14,841, $7,229 and $45,663, respectively. Cost of energy revenues
increased for 1997 primarily due to only six months of costs reported in the
1996 transition period. Cost of energy revenues decreased for the 1996
transition period as compared to 1996 primarily due to only six months of costs
reported in the 1996 transition period and the result of the amended PPAs in
which JCP&L began assuming the cost of fuel for the Parlin and Newark
facilities.

         Cost of equipment sales and service for 1997, for the 1996 transition
period and 1996 were $17,037, $12,365 and $22,153, respectively. The 1997
increase was primarily due to only six months of costs reported in the 1996
transition period, except for the operations of PUMA which included nine months
of costs for the 1996 transition period, and to the recording of $190 of
inventory write-downs in the fourth quarter. Cost of equipment sales and service
decreased for the 1996 transition period as compared to 1996 primarily due to
only six months of costs reported in the 1996 transition period.

         Cost of rental revenues for 1997, for the 1996 transition period and
1996 were $1,817, $834 and $1,406, respectively. The fluctuations were primarily
due to only six months of costs reported in the 1996 transition period.

         There were no development fee expenses and other costs for 1997. Cost
of development fees and other for the 1996 transition period and 1996 were
$1,559 and $2,531, respectively. These costs consist principally of costs
associated with the sale of various projects either under development or in
operation.

         The Company's gross profit was $31,109, $17,929, and $24,794 for 1997,
for the 1996 transition period and for 1996, respectively. The higher gross
margin for 1997 is due to only six months of operations included in the 1996
transition period. The gross margin for the 1996 transition period decreased
from 1996 due to only six months of operations included in the 1996 transition
period and to fluctuations in the recovery of fuel costs through energy revenues
under the Parlin and Newark Project PPAs in effect until April 30, 1996.

         PROVISION FOR IMPAIRED ASSETS

         During the 1997 fourth quarter, the Company recorded provisions for
impaired assets in the aggregate amount of $5,274 for various asset disposals,
write-offs and write-downs. The impairment charge reduced identifiable assets of
the energy segment and the equipment sales, rental and service segment by
approximately $697 and $2,161, respectively, and corporate assets by $2,416. The
components of the charge were as follows:

</TABLE>

To improve liquidity, in fiscal 1994 the Company initiated efforts to liquidate
specific power generation equipment that was not in use in an operating project,
rented to a customer or critical to the completion of projects in development.
These assets, consisting mainly of gas and steam turbines, were written down in
fiscal 1994 and 1995 to liquidation values determined by independent appraisal,
reclassified on the balance sheet as "equipment held for sale" and no longer
depreciated. The $3,228 carrying value of the equipment at June 30, 1995 was
reduced to $2,628 and $1,598 at December 31, 1996 and September 30, 1997,
respectively, through periodic sales. In the 1997 fourth quarter, due to lack of
interest by potential buyers, the remaining equipment was scrapped resulting in
an impairment charge of $1,553.

Impairment charges for property, plant and equipment disposals totaled $1,801,
comprised of losses of $779 from disposal of other power generating equipment,
and write-offs of $1,023 for equipment that was determined to be non-useable or
could not be located during asset counts and inspections performed at OES and
the PWD Project. The asset counts and inspections were undertaken as part of the
overall review performed to determine whether OES and PWD Project operations
should be continued. In addition, the PWD Project asset counts were required in
order to pledge the equipment as security for a new corporate revolving credit
facility which the Company entered into with Meespierson Capital Corp. Prior to
the 1997 fourth quarter, physical counts of the equipment were last performed in
fiscal 1995 during the period of bankruptcy reorganization.

The asset impairment charge also included $371 to write-off capitalized project
development costs related to certain development projects that were terminated.

During the 1997 fourth quarter, the Company completed a thorough review of its
business operations and market opportunities to determine whether operations of
the PWD Project and the equipment sales, rental and service businesses should be
continued. The board of directors determined that the PWD Project should be
retained and that the equipment sales, rental and service segment should be
exited.

The equipment sales, rental and service segment has not been reported as a
discontinued operation 


                                       43
<PAGE>

because of uncertainties about the expected timing and manner of disposal.
However, management performed an impairment review of the segment's long-lived
assets as required by SFAS No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of." Based on an analysis of
estimated future cash flows, the carrying value of OES' generator equipment was
determined to be impaired. Consequently, a provision of $976 was recorded to
write-down the assets to their estimated fair value as determined by management
based on sales values of similar equipment.

Management also evaluated the carrying value of its 50% investment in PoweRent.
Due to PoweRent's low earnings capacity, combined with the expectation of
exiting this business in the near term, the investment was determined to be
permanently impaired. The carrying value of the investment was written down by
$500 based on discussions with potential buyers and management's estimate of the
investment value.

During the year ended June 30, 1996, unrecoverable project development costs of
$180 were written off.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

         SG&A expenses for 1997, the 1996 transition period and 1996 were
$9,479, $6,149 and $12,612, respectively. SG&A increased for 1997 primarily due
to only six months of costs reported in the 1996 transition period, except for
the operations of PUMA which included nine months of costs for the 1996
transition period, and due to the recording of $914 in the fourth quarter for
various staffing and relocation costs and other reserves. SG&A decreased for the
1996 transition period as compared to 1996 primarily due to only six months of
costs reported in the 1996 transition period. 1996 includes a $3,100 cost
incurred to terminate an interest rate swap agreement in connection with the
Parlin nonrecourse project debt refinancing.

         INTEREST AND OTHER INCOME

         Interest and other income for 1997, the 1996 transition period and 1996
were $1,205, $251 and $508, respectively. Interest and other income increased
for 1997 primarily due to only six months of income reported in the 1996
transition period, the settlement of a legal suit, and the sale of a development
project in Pakistan, offset in part by fees paid to Wexford Management LLC under
a Liquidating Asset Management Agreement entered into in connection with its
emergence from bankruptcy and the sale of unused equipment. Interest and other
income for the 1996 transition period was positively impacted by interest income
earned on escrow account balances established in connection with the nonrecourse
financing on the Parlin and Newark facilities.

         REORGANIZATION COSTS

         Reorganization costs represent all costs incurred after filing
bankruptcy that relate to the Company's reorganization and restructuring
efforts. Reorganization costs for 1996 were $12,101 and consist primarily of
professional and administrative fees and expenses.

         INTEREST AND DEBT EXPENSE

         Interest and debt expense for 1997, the 1996 transition period and 1996
were $14,768, $7,681 and $18,646, respectively. Interest and debt expense
increased for 1997 as compared to 


                                       44
<PAGE>

the 1996 transition period primarily due to only six months of expense reported
in the 1996 transition period. Interest and debt expense decreased for the 1996
transition period as compared to 1996 primarily due to only six months of
expenses reported in the 1996 transition period and to the refinancing of the
Parlin and Newark Projects. 1996 interest and debt expense includes
post-petition interest on prepetition liabilities of $6,487. 1996 also includes
$1,098 in interest costs associated with loans provided by NRG Energy and $1,433
of deferred financing costs attributable to the nonrecourse debt relating to the
Parlin and Newark Projects which were refinanced during the year (see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources").

         EXTRAORDINARY ITEM

         In the 1996 transition period, the Company negotiated a buyout of a
subsidiary's capital lease obligation. The lender agreed to accept a $1,100
payment in full satisfaction of the lease. The transaction resulted in an
extraordinary gain of $1,643 (net of $124 of state income taxes).

         INCOME TAXES

         For 1997, the 1996 transition period and 1996, the Company recorded an
income tax benefit of $20,454, $268 and $463, respectively. The benefit for 1997
was attributable to the reduction of a deferred tax asset valuation reserve
previously established for net operating losses incurred by the Company from
1992 to 1996. The income tax benefit for the 1996 transition period and for 1996
was attributable to the utilization of state net operating loss carryforwards.

         NET INCOME (LOSS) AND EARNINGS (LOSS) PER SHARE

         Net income for 1997 was $23,352 compared to net income for the 1996
transition period of $6,423 and a net loss for 1996 of $17,713. The basic
earnings per share for 1997 was $3.59 compared to basic earnings per share for
the 1996 transition period of $1.00 and basic losses per share for 1996 of
$4.24.

         The increase in 1997 net income and earnings per share was primarily
due to the income tax benefit recognized upon reduction of the deferred tax
asset valuation reserve, less the impairment provision to write-down and
write-off certain assets. Net income and earnings per share for the 1996
transition period increased from the net loss in 1996 primarily due to the
non-recurring bankruptcy reorganization costs incurred in 1996.

LIQUIDITY AND CAPITAL RESOURCES

         The development, construction and operation of cogeneration projects
and other power generation facilities requires significant capital.
Historically, the Company has employed substantial leverage at both the project
and parent company level to finance its capital requirements. Debt financing at
the project level is typically nonrecourse to the parent. Nonrecourse project
financing agreements usually require initial equity investments at the project
level. The Company has financed such equity investments through cash generated
from operations and other borrowings, including borrowings at the parent level.

         Almost all of the Company's operations are conducted through
subsidiaries and other affiliates. As a result, the Company depends almost
entirely upon their earnings and cash flow to service consolidated indebtedness,
including indebtedness of the parent, CogenAmerica. The 


                                       45
<PAGE>

nonrecourse project financing agreements of certain subsidiaries and other
affiliates generally restrict their ability to pay dividends, make distributions
or otherwise transfer funds to the parent prior to the payment of other
obligations, including operating expenses, debt service and reserves.

         At December 31, 1998, consolidated long-term indebtedness (including 
current maturities) totals $285,096, consisting of nonrecourse project 
borrowings in the aggregate amount of $197,908, project borrowings with 
recourse to the parent of $21,775, $25,000 outstanding under a revolving 
credit facility and borrowings from NRG Energy of $40,413. Of the total 
long-term indebtedness, borrowings with recourse to the parent totaled 
$87,188 at December 31, 1998, consisting of borrowings under the revolving 
credit facility and from NRG Energy, and a guarantee by the parent of $21,775 
of the Parlin and Newark project borrowings. NRG Energy also has provided a 
corporate guarantee of $3,000, of certain pre-existing liabilities of Parlin 
and Newark as of May 23, 1996.

         At December 31, 1998, cash and cash equivalents totaled $3,568 and 
restricted cash totaled $12,135. The restricted cash primarily represents 
escrow funds required by the terms of credit agreements for the Newark, 
Parlin and Morris projects.

         Cash provided by operating activities was $17,571, $16,989 and $1,056
for 1998, 1997 and the 1996 transition period, respectively. In 1996 cash used
by operating activities was $8,050. Cash provided by operations in 1998
increased from 1997 primarily due to higher depreciation and amortization
expense. Cash provided by operating activities in 1997 increased from the 1996
transition period due to only six months of operations included in the 1996
transition period and improved working capital cash management. Cash used by
operating activities in 1996 resulted from the net loss incurred during the
period the Company emerged from bankruptcy.

         Cash used by investing activities was $74,274, $14,484 and $776 in
1998, 1997 and the 1996 transition period, respectively. During 1996 cash
provided by investing activities was $1,604.

         Cash used by investing activities in 1998 primarily represents 
capital expenditures of $73,406 to complete construction of the Morris 
project and upgrade other facilities, and net deposits of $3,578 into 
restricted cash accounts as required by certain credit agreements. These uses 
of cash were offset by proceeds of $2,686 from the sale of OES and other 
assets.

         Cash used by investing activities in 1997 primarily represents 
capital expenditures of $5,858 for the Newark and Parlin Project improvements 
and an equity contribution of $10,000 to the Grays Ferry Partnership. These 
uses of cash were reduced by collection of notes receivable of $1,175 and 
proceeds of $552 from the sale of certain assets.

         Cash used by investing activities for the 1996 transition period 
primarily resulted from expenditures of $1,315 for capital improvements and 
project development activities, less net withdrawals from restricted cash 
accounts.

         Cash provided by investing activities in 1996 primarily reflected 
$7,500 proceeds from the sale of certain subsidiaries in connection with the 
Company's bankruptcy plan, less $1,783 for capital expenditures and project 
development activities and less $5,156 for net deposits into restricted cash 
accounts.

                                       46
<PAGE>


         Cash provided by (used in) financing activities was $56,827, $(2,248),
$(2,115) and $7,385 for 1998, 1997, the 1996 transition period and 1996.

         During 1998, proceeds from long-term debt totaled $67,771, consisting
of construction loan draws of $54,450, and $12,027 of loans from NRG Energy
related to the Morris project. Repayments of long-term debt totaled $10,142.

         1998 Non-cash investing and financing activities include $23,890 for
acquisition of the Pryor Project and $6,230 of capital expenditures for the 
Morris Project included in liabilities.

         The Company evaluates current and forecasted cash flow as a basis for
financing operating requirements and capital expenditures. Management believes
there is sufficient liquidity from cash flow from operations and working capital
to finance recurring capital expenditures and to fund working capital
requirements, including scheduled debt service, for the next twelve months.

         In May 1996, the Company's wholly-owned subsidiaries CogenAmerica 
Newark and CogenAmerica Parlin entered into a credit agreement (the "Newark 
and Parlin Credit Agreement") which established provisions for a $155,000 
fifteen-year loan and a $5,000 five-year debt service reserve line of credit. 
The loan is secured by all of CogenAmerica Newark's and CogenAmerica Parlin's 
assets and a pledge of the capital stock of such subsidiaries. The Company 
has guaranteed repayment of UP TO $21,775 of the amount outstanding under the 
Credit Agreement. The interest rate on the outstanding principal is variable 
based on, at the option of CogenAmerica Newark and CogenAmerica Parlin, LIBOR 
plus a 1.125% margin or a defined base rate plus a 0.375% margin, with 
nominal margin increases in the sixth and eleventh year. For any quarterly 
period where the debt service coverage ratio is in excess of 1.4:1, both 
margins are reduced by 0.125%. Concurrently with the Newark and Parlin Credit 
Agreement, CogenAmerica Newark and CogenAmerica Parlin entered into an 
interest rate swap agreement with respect to 50% of the principal amount 
outstanding under the Credit Agreement. This interest rate swap agreement 
fixes the interest rate on such principal amount ($77,500 at December 31, 
1998) at 6.9% plus the margin. At December 31, 1998, the principal amount 
outstanding under the credit agreement was $134,927.

         The Company used the proceeds of the loan under the Newark and Parlin
Credit Agreement to repay certain preexisting obligations of the Company
including $87,291 of indebtedness to NRG Energy. NRG Energy provided the Company
loans of which $40,413, $4,439, $14,388 and $101,679 was outstanding at December
31, 1998, 1997, 1996 and June 30, 1996, respectively.

         CogenAmerica Schuylkill, a wholly-owned subsidiary of the Company, owns
a one-third partnership interest in the Grays Ferry Project which commenced
operation in January 1998. In March 1996, the Grays Ferry Partnership entered
into a credit agreement with Chase to finance the project. The credit agreement
obligated each of the project's three partners to make a $10,000 capital
contribution prior to the commercial operation of the facility. The Company made
its required capital contribution in 1997. NRG Energy entered into a loan
commitment to provide CogenAmerica Schuylkill the funding, if needed, for the
CogenAmerica Schuylkill capital contribution obligation to the Grays Ferry
Partnership. Prior to December 31, 1997, CogenAmerica Schuylkill had borrowed
$10,000 from NRG Energy under this loan agreement, of which $1,900 remained
outstanding to NRG Energy at December 31, 1998.


                                       47
<PAGE>


         In connection with its acquisition of the Morris Project, 
CogenAmerica Funding, a wholly-owned subsidiary of the Company, assumed all 
of the obligations of NRG Energy to provide future equity contributions to 
the project, which obligations are limited to the lesser of 20% of the total 
project cost or $22,000. NRG Energy has guaranteed to the Morris Project's 
lenders that CogenAmerica Funding will make these future equity 
contributions, and the Company has guaranteed to NRG Energy the obligation of 
CogenAmerica Funding to make these future equity contributions (which 
guarantee is secured by a second priority lien on the Company's interest in 
the Morris Project). In addition, NRG Energy has committed in a Supplemental 
Loan Agreement between the Company, CogenAmerica Funding and NRG Energy to 
loan CogenAmerica Funding and the Company (as co-borrowers) the full amount 
of such equity contributions by CogenAmerica Funding, subject to certain 
conditions precedent, at CogenAmerica Funding's option. Any such loan will be 
secured by a second priority lien on all of the membership interests of the 
project and will be recourse to CogenAmerica Funding and the Company. 
Effective November 30, 1998 the Company and NRG Energy agreed to a First 
Amendment to the Supplemental Loan Agreement that allowed the Company to 
contribute the $22,000 of equity in installments to match the construction 
draw payments. At December 31, 1998, $12,027 had been drawn and contributed 
as equity. Subsequent to year end, additional draws and equity fundings have 
been made and as of March 26, 1999, the entire $22,000 had been drawn and 
contributed as equity. The Supplemental Loan Agreement calls for an interest 
rate of prime plus 1.5%. Effective with the First Amendment the interest rate 
was changed to prime plus 3.5% until the possible event of default related to 
the Grays Ferry Project has been eliminated. This additional interest rate 
resulted in an additional $35 of interest expense for the Morris Project in 
1998. On February 16, 1999 NRG Energy agreed to reduce the interest rate 
under the loan back to prime plus 1.5%. This adjustment was made effective 
January 1, 1999. At December 31, 1998, $12,027 was due NRG Energy under the 
Supplemental Loan Agreement.

         On December 17, 1997, the Company entered into the MeesPierson Credit
Agreement providing for a $30,000 reducing revolving credit facility. The
facility is secured by the assets and cash flows of the PWD Project as well as
the distributable cash flows of the Parlin and Newark Projects, and the Grays
Ferry Partnership. On December 19, 1997 the Company borrowed $25,000 under this
facility. The proceeds were used to repay $16,949 to NRG Energy, to repay $6,551
of obligations of the PWD Project and $1,500 for general corporate purposes. The
MeesPierson Credit Agreement includes cross default provisions that cause
defaults to occur in the event certain defaults or other adverse events occur
under certain other instruments or agreements (including financing and other
project documents) to which the Company or one or more of its subsidiaries or
other entities in which it owns an ownership interest is a party. The actions
taken by the power purchaser of the Grays Ferry Project have resulted in a cross
default under the MeesPierson Credit Agreement. Repayment of the MeesPierson
Credit Agreement has not been accelerated and the lender has waived such default
and the Company has agreed not to draw any additional amounts under the
MeesPierson Credit Agreement. On August 14, 1998 the lender agreed to continue
the waiver on the default until July 1, 1999 by imposing a 2.0% increase in the
interest rate effective October 1, 1998. This additional interest rate increased
interest expense by $126 for the year ended December 31, 1998. On February 12,
1999 the lender agreed to a permanent waiver of the Grays Ferry Project cross
default and eliminated the 2.0% increase in the interest rate effective January
1, 1999. The Company also reduced the size of the facility to $25,000. The
repayment of the $25,000 is due in full on December 17, 2000.

         The Company's principal credit agreements (including the Newark and
Parlin Credit Agreement) include cross-default provisions that generally permit
its lenders to accelerate the 


                                       48
<PAGE>

indebtedness owed thereunder, to decline to make available any additional
amounts for borrowing thereunder, and to exercise certain other remedies in
respect of any collateral securing such indebtedness in the event certain
defaults or other adverse events occur under certain other instruments or
agreements (including financing and other project documents) to which the
Company or one or more of its subsidiaries or other entities in which it owns an
ownership interest is a party. As a result, a default under one such other
instrument or agreement could have a material adverse effect on the Company by
causing one or more cross-defaults to occur under one or more of the Company's
principal credit agreements, potentially having one or more of the effects set
forth above and otherwise adversely affecting the Company's liquidity and
capital position.

         During 1998 the Company incurred approximately $1,001 of third-party
costs related to a capital markets financing transaction expected to be
completed during 1999. These costs have been deferred and are included in the
balance sheet as "Deferred financing costs, net." If the Company elects to
pursue an alternative financing, such as through the commercial bank market, or
if the financing currently contemplated for the capital markets is indefinitely
delayed or discontinued, it will have to expense the financing costs that have
been deferred.

         On October 9, 1998, CogenAmerica Pryor, a wholly-owned subsidiary of
CogenAmerica, acquired from MCPC the entire interest in a 110 MW cogeneration
project, the Pryor project, located in the Mid-America Industrial Park, in
Pryor, Oklahoma. CogenAmerica Pryor acquired the Pryor Project by purchasing
from MCPC all of the issued and outstanding stock of OLAC for a cash purchase
price of approximately $23,900.

         NRG Energy has loaned the Company and CogenAmerica Pryor 
approximately $23,900 to finance the acquisition. The loan is a six-year term 
facility calling for principal and interest payments on a quarterly basis, 
based on project cash flows. The interest rate on the note relating to such 
loan was initially set at prime rate plus 3.5% and such rate reduces by two 
percentage points upon the occurrence of certain events related to 
elimination of default risk under the loan. On February 16, 1999 NRG Energy 
agreed to reduce the interest rate under the loan to prime plus 1.5%. This 
adjustment was made effective January 1, 1999.

SALE OF OES

         On November 5, 1998 the Company sold OES, a wholly-owned subsidiary of
the Company, in a stock transaction to an unrelated third party. The sales price
was $2,000 and the Company recorded a gain on the sale. The Company recorded
revenue from OES of $8,343 for fiscal 1998. This transaction did not have a
material impact on the Company's results of operations or financial position.

YEAR 2000

         The Year 2000 issue refers generally to the data structure problem that
may prevent systems from properly recognizing dates after the year 1999. The
Year 2000 issue affects information technology ("IT") systems, such as computer
programs and various types of electronic equipment that process date information
by using only two digits rather than four digits to define the applicable year,
and thus may recognize a date using "00" as the year 1900 rather than the year
2000. The issue also affects some non-IT systems, such as devices which rely on
a microcontroller to process date information. The Year 2000 issue could result
in system failures or miscalculations, causing disruptions of a company's
operations. Moreover, even if a company's 


                                       49
<PAGE>

systems are Year 2000 compliant, a problem may exist to the extent that the data
that such systems process is not.

         The following discussion contains forward-looking statements reflecting
management's current assessment and estimates with respect to the Company's Year
2000 compliance efforts and the impact of Year 2000 issues on the Company's
business and operations. Various factors, many of which are beyond the control
of the Company, could cause actual plans and results to differ materially from
those contemplated by such assessments, estimates and forward-looking
statements. Some of these factors include, but are not limited to,
representations by the Company's vendors and counterparties, technological
advances, economic considerations and consumer perceptions. The Company's Year
2000 compliance program is an ongoing process involving continual evaluation and
may be subject to change in response to new developments.

         THE COMPANY'S STATE OF READINESS

         The Company has implemented a Year 2000 compliance program designed to
ensure that the Company's computer systems and applications will function
properly beyond 1999. The Company believes that it has allocated adequate
resources for this purpose and expects its Year 2000 conversions to be completed
on a timely basis. In light of its compliance efforts, the Company does not
believe that the Year 2000 issue will materially adversely affect operations or
results of operations, and does not expect implementation to have a material
impact on the Company's financial statements. However, there can be no assurance
that the Company's systems will be Year 2000 compliant prior to December 31,
1999, or that the failure of any such system will not have a material adverse
effect on the Company's business, operating results and financial condition. In
addition, to the extent the Year 2000 problem has a material adverse effect on
the business, operations or financial condition of third parties with whom the
Company has material relationships, such as vendors, suppliers and customers,
the Year 2000 problem could have a material adverse effect on the Company's
business, results of operations and financial condition.

         IT SYSTEMS. The Company has reviewed and continues to review all of its
IT systems as they relate to the Year 2000 issue. The Company's accounting
system has been upgraded to alleviate any potential Year 2000 issues. The
Company outsources its human resource and payroll systems and is in the process
of working with the outside vendor to identify and correct any potential Year
2000 issues. This process is expected to be complete and any changes implemented
by December 31, 1999. The Company's billing systems are either provided by the
customer or are performed internally on microcomputer systems. In these cases,
the collection of data is the most important feature and any impact from a Year
2000 issue is expected to be immaterial.

         NON-IT SYSTEMS. As indicated above, the Company is dependent upon some
of its customers for billing data related to the amount of electricity and steam
sold and delivered during the month. For the most part, the collection of this
data is done mechanically rather than electronically. Only data storage is
managed electronically. The collection of this data also occurs within the
control systems of the Company's various facilities. The Company has requested
that the control system vendors audit their software to identify any potential
Year 2000 issues and provide recommendations for alleviating any potential
problems. This process has been completed for all of the Company's facilities
and the various solutions have been implemented. The Company does not believe
that any further upgrades, if necessary, will be material to its financial
condition or results of operation.

         YEAR 2000 ISSUES RELATING TO THIRD PARTIES. As described above, the
Company, in some cases, is dependent upon certain customers to provide billing
data. However, the Company also captures and processes this data as a
redundancy. The Company's control systems have been upgraded as described above
and the Company does not believe that any loss of data will occur due to a Year
2000 issue. In addition, the Company's third parties are major utilities and
sophisticated industrial concerns who are participants in sophisticated Year
2000 readiness programs. The Company has participated in numerous vendor surveys
to determine the readiness of various Company systems for any potential Year
2000 issues. In addition, the Company has obtained written disclosure from a
number of vendors relating to their Year 2000 preparedness.

         COSTS TO ADDRESS THE COMPANY'S YEAR 2000 ISSUES

         The Company's costs to review and assess the Year 2000 issue have not
been material. The Company believes that its future costs to implement Year 2000
solutions will also be immaterial to the financial statements.

         THE RISKS OF THE COMPANY'S YEAR 2000 ISSUES

         The Company believes that its most likely Year 2000 worst case scenario
would be the loss of billing data to utilities and industrial companies which
purchase the Company's electricity and steam. This billing information, as
explained above, is also captured by the Company's control systems at its
various facilities.

         THE COMPANY'S CONTINGENCY PLANS

         As described above, the contingency plan for the loss of billing data
is to use the data provided by the Company's internal control systems which are
in the process of being upgraded to eliminate any Year 2000 issues.

NEW ACCOUNTING STANDARDS

         In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
Comprehensive Income." SFAS No. 130 establishes standards for reporting and
display of comprehensive income and its components. The Company adopted the
statement in 1998. The adoption had no affect on the Company's results of
operations, cash flows or financial position.

         In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related Information". SFAS No. 131 establishes standards
for the way that public companies report information about operating segments in
annual financial statements and requires reporting of selected information about
operating segments in interim financial statements issued to the public. It also
establishes standards for disclosures regarding products and services,
geographic area and major customers. As required, the Company adopted the
disclosure requirements for annual financial statements in 1998. The interim
reporting requirements will be adopted beginning with the Company's quarterly
report on Form 10-Q for the quarter ending March 31, 1999.

         In April 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") No. 98-5, "Reporting the Costs of
Start-Up Activities," which is effective for financial statements for fiscal
years beginning after December 15, 1998. For the 


                                       51
<PAGE>

purposes of this SOP, start-up activities are broadly defined as those one-time
activities related to opening a new facility, conducting business in a new
territory, conducting business with a new class of customer or beneficiary,
initiating a new process in an existing facility, or commencing some new
operation. Start-up activities are also defined to include activities related to
organizing a new entity. The Company assessed the impact and adopted SOP 98-5 as
of December 31, 1998, and determined it to be immaterial to the consolidated
financial statements.

         In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 is required to be adopted for
fiscal years beginning after June 15, 1999 (fiscal year 2000 for the Company).
SFAS 133 requires that all derivative instruments be recorded on the balance
sheet at their fair value. Changes in the fair value of derivatives are to be
recorded each period in current earnings or other comprehensive income,
depending on whether a derivative is designated as part of a hedge transaction
and, if it is the type of hedge transaction. Management has not yet determined
the impact that adoption of SFAS No. 133 will have on its earnings or financial
position, but it may increase earnings volatility.


ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

         The Company's market risk is primarily impacted by changes in interest
rates and changes in natural gas prices.

         The Company's strategy is to mitigate fuel supply price risk at the
facilities through the use of several methods. At the Newark and Parlin
Projects, the customer is responsible for natural gas supply and delivery. The
customer is the fuel manager at the Morris Project with all costs of supplying
gas treated as pass-through to the customer. The Pryor Project bases sales
prices of energy on the weighted average cost of fuel. The Gray's Ferry Project
has obtained fuel supply contracts to limit risk of fluctuating fuel prices. The
Company does not hold or issue derivative instruments to hedge future fuel price
fluctuations.

         The table below provides information about the Company's financial
instruments that are sensitive to changes in interest rates, including debt
obligations and interest rate swaps. For debt obligations the table presents
principal cash flows and related weighted average interest rates by expected
maturity dates. For interest rate swaps, the table presents notional amounts and
weighted average interest rates by contractual maturity dates. The information
is presented in U.S. dollar equivalents, which is the reporting currency. The
instrument's actual cash flows are denominated in both U.S. dollars ($US) and
British Sterling (L), as indicated in parentheses.

COGENERATION CORPORATION OF AMERICA
CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 1998


<PAGE>



            REPORT OF INDEPENDENT ACCOUNTANTS


            To the Stockholders and Board of Directors
            of Cogeneration Corporation of America

            In our opinion, the accompanying consolidated balance sheets and the
            related consolidated statements of operations, of stockholders'
            equity (deficit) and of cash flows present fairly, in all material
            respects, the financial position of Cogeneration Corporation of
            America and its subsidiaries at December 31, 1998 and 1997, and the
            results of their operations and their cash flows for the years ended
            December 31, 1998 and 1997, the six months ended December 31, 1996,
            and the year ended June 30, 1996, in conformity with generally
            accepted accounting principles. These financial statements are the
            responsibility of the Company's management; our responsibility is to
            express an opinion on these financial statements based on our
            audits. We conducted our audits of these statements in accordance
            with generally accepted auditing standards which require that we
            plan and perform the audits to obtain reasonable assurance about
            whether the financial statements are free of material misstatement.
            An audit includes examining, on a test basis, evidence supporting
            the amounts and disclosures in the financial statements, assessing
            the accounting principles used and significant estimates made by
            management, and evaluating the overall financial statement
            presentation. We believe that our audits provide a reasonable basis

PRECEDE ITEM 1.

1.   Business and Emergence from Bankruptcy

Cogeneration Corporation of America ("CogenAmerica" or the "Company"), formerly
known as NRG Generating (U.S.) Inc., is an independent power producer pursuing
"inside-the-fence" cogeneration projects in the U.S. The Company is engaged
primarily in the business of developing, owning and managing the operation of
cogeneration projects which produce electricity and thermal energy for sale
under long-term contracts with industrial and commercial users and public
utilities. The Company is currently focusing on natural gas-fired cogeneration
projects with long-term contracts for substantially all of the output of such
projects. In addition, the Company sells and rents power generation and
standby/peak shaving equipment and services.

On April 30, 1996, O'Brien Environmental Energy, Inc. ("O'Brien"), the formerly
named parent company, emerged from bankruptcy pursuant to the Plan submitted by
NRG Energy, Inc. ("NRG Energy"), the O'Brien Official Committee of Equity
Security Holders and Wexford Management Corporation ("Wexford") and approved by
the U.S. Bankruptcy Court for the District of New Jersey (the "Court"). The Plan
awarded NRG Energy the rights to acquire a 41.86% equity interest in the Company
and generally provided for full and immediate payment of all undisputed
prepetition liabilities and included a provision for post-petition interest.
O'Brien was renamed on the April 30, 1996 closing date to NRG Generating (U.S.)
Inc.

O'Brien filed a voluntary petition for reorganization under Chapter 11 of the
United States Bankruptcy Code with the Court on September 28, 1994 to pursue
financial restructuring efforts under the protection afforded by the U.S.
bankruptcy laws. The decision to seek Chapter 11 relief was based on the
conclusion that action had to be taken to preserve its business relationships,
restructure its debt and maintain the operational strength and assets of the
Company. The Company continued its normal operations as Debtor-in-Possession
during the bankruptcy period but could not engage in transactions outside the
ordinary course of business without approval of the Court.

On April 30, 1996, NRG Energy funded approximately $107,418 in accordance with
the Plan and O'Brien's existing Class A and Class B common stock was canceled
and became exchangeable for 3,764,457 (58.14%) shares of new common stock. The
NRG Energy funding was comprised of: $71,240 advanced under the terms of three
loan agreements; $21,178 to purchase 2,710,357 (41.86%) of new common stock;
$7,500 for the purchase of ten wholly-owned subsidiaries of O'Brien; and $7,500
deposited with the Company's stock transfer agent representing a cash
distribution of approximately $0.44 per share by NRG Energy to O'Brien's Class A
and Class B common stockholders.

On April 30, 1996 the Company also issued 49,574 shares of series A, 13.5%
cumulative preferred stock to Wexford in satisfaction of $4,957 of prepetition
unsecured claims allowed by the Court. The preferred shares were redeemed by the
Company in May 1996 for $4,957 plus $57 in dividends.

The funds received from NRG Energy were disbursed according to the Plan's terms
which generally provided for full payment (or cure/reinstatement) of all
undisputed prepetition liabilities including the payment of post-petition
interest on most prepetition obligations. Additionally, disbursements were made
to certain creditors of subsidiary companies whose obligations were not included
in prepetition liabilities and for professional fees incurred during the
bankruptcy proceedings. Certain other bankruptcy claims filed with the Court
remain in dispute and are classified on the balance sheet as 


                                      F-6
<PAGE>

"prepetition liabilities." An escrow fund has been established to fully reserve
the remaining disputed claims submitted to the Court. Any remaining escrow funds
resulting from the Court disallowing any disputed claims will be disbursed pro
rata to all reinstated creditor claimholders as additional post-petition
interest.

In accordance with the Plan, on April 30, 1996 the Company and Wexford entered
into a Liquidating Asset Management Agreement whereby Wexford agreed to assist
the Company with the possible liquidation of certain specified assets consisting
of (a) the Company's equipment sales, rental and services business operated by
its subsidiaries OES and PUMA, (b) the PWD Project, (c) certain unused
equipment, and (d) American Hydrotherm Corporation ("American Hydrotherm") and
two other related subsidiaries. During 1996 and 1997, the unused equipment,
American Hydrotherm and the two other related subsidiaries were sold or
otherwise disposed. In the fourth quarter of 1997, the board of directors
decided to retain the PWD Project and determined that the equipment sales,
rental and services business is not a part of the Company's strategic plan for
the future and would be disposed. Consistent with the board of directors'
determination to exit this business, OES was sold in November 1998 (see Note 6)
and possible alternatives for the disposition of PUMA continued to be pursued.
In accordance with the agreement and as approved by the Court, the Company paid
Wexford $1,219, and $281 in compensation for services during the year ended
December 31, 1997 and six months ended December 31, 1996.

2.   Summary of Significant Accounting Policies

BASIS OF PRESENTATION

The consolidated financial statements include the accounts of all majority-owned
subsidiaries and all significant intercompany balances and transactions have
been eliminated. Investments in companies, partnerships and projects that are
more than 20% but less than majority-owned are accounted for by the equity
method.

Effective July 1, 1996, the Company changed its year end from June 30 to
December 31. The Company filed a transition Report on Form 10-K for the period
July 1, to December 31, 1996. The periods presented in the Company's
consolidated statements of operations, stockholders' equity (deficit) and of
cash flows are for the twelve months ended December 31, 1998 and 1997, the six
months ended December 31, 1996 and the twelve months ended June 30, 1996. The
twelve months ended June 30, 1996 are sometimes referred to in these Notes to
Consolidated Financial Statements as fiscal 1996.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosures of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from these estimates.

REORGANIZATION COSTS AND PREPETITION LIABILITIES

Expenses incurred after filing bankruptcy related to the Company's
reorganization and restructuring efforts have been presented in the consolidated
statement of operations as reorganization costs. Liabilities which remain
subject to the bankruptcy proceeding are classified on the balance sheet as
prepetition liabilities and include provisions for post-petition interest.


                                      F-7
<PAGE>


REVENUE RECOGNITION

Energy revenues from cogeneration projects are recognized as electricity and
steam are delivered. Revenue from sales and rental of power generation equipment
are recognized upon shipment or over the term of the rental. Development fee
revenue is generally recognized on a cost recovery basis as cash is received
(without future lending provisions).

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with maturities of three
months or less at the time of purchase to be cash equivalents.

INVENTORIES

Inventories, consisting principally of power generation equipment and related
parts held for sale, are valued at the lower of cost (determined primarily by
the specific identification method) or market.

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment is stated at cost less accumulated depreciation.
When assets are disposed of, the cost and related accumulated depreciation are
removed from the accounts and the resulting gains or losses are included in
results of operations. The cost of property, plant and equipment, net of
estimated salvage value is depreciated using the straight-line method over the
useful lives of the assets which range from five to thirty years. It is
reasonably possible that the estimated useful lives or salvage values could
differ materially in the near term from the amounts assumed in arriving at
current depreciation expense. These estimates are affected by such factors as
the Company's overhaul, repair and maintenance activities, the ability of the
Company to continue selling electricity and steam to customers under existing
long-term contracts, changes in estimated prices of electricity and steam as
well as alternative sources of energy and changes in the regulatory environment.

Cost of maintenance and repairs is charged to expense as incurred. Betterments
and improvements are capitalized. During the years ended December 31, 1998 and
1997, the Company capitalized interest in connection with the construction of
power plants of $4,465 and $744, respectively. No interest was capitalized
during the six months ended December 31, 1996 or the year ended June 30, 1996.

PROJECT DEVELOPMENT COSTS

Project development costs consist of fees, licenses, permits, site testing, bids
and other charges, including employee costs, incurred incidental to specific
projects under development. Project development costs are expensed in any period
in which management determines the costs to be unrecoverable.

DEFERRED FINANCING COSTS

Financing costs are deferred and amortized on a straight-line basis over the
term of the related debt, which is comparable to results using the effective
interest method. Interest expense includes amortization of $516, $407, $199, and
$1,480 for the years ended December 31, 1998 and 1997, the six months ended
December 31, 1996 and the year ended June 30, 1996, respectively. Accumulated
amortization was $1,101 and $585 at December 31, 1998 and 1997, respectively.

OTHER ASSETS

Other assets include $16,470 (net of accumulated amortization of $110) at
December 31, 1998 for 


                                      F-8
<PAGE>


capitalized project development costs related to the Morris Project. The 
capitalized project development costs are amortized by the straight-line 
method over the 25-year life of the project.

NONRECOURSE LONG-TERM DEBT

Nonrecourse long-term debt consists of project financing for which the repayment
obligation is limited to specific project subsidiaries.

INCOME TAXES

The Company accounts for income taxes under Statement of Financial Accounting
Standards ("SFAS") No. 109. SFAS No. 109 is an asset and liability approach that
requires the recognition of deferred tax assets and liabilities for the expected
future tax consequences of temporary differences between the carrying amounts
and tax basis of other assets and liabilities. Valuation allowances are recorded
when it is more likely than not that a tax benefit will not be realized.

INTEREST RATE SWAP AGREEMENT

The Company has entered into an interest rate swap agreement to reduce the
impact of changes in interest rates on certain of its variable rate long-term
debt. The differentials paid or received under the swap agreement are accrued
and recorded as adjustments to interest expense.

FOREIGN CURRENCY TRANSLATION

The accounts of foreign subsidiaries have been translated in accordance with
SFAS No. 52, whereby assets and liabilities are translated at rates of exchange
existing at the balance sheet date and revenues and expenses are translated at
the average rates of exchange for the period.

CONCENTRATION OF CREDIT RISK

The Company primarily sells electricity and steam to industrial and commercial
users and public utilities under long-term agreements. The Company also sells,
rents and services power generation equipment to various entities worldwide. The
Company performs on-going credit evaluations of its customers and generally does
not require collateral. The Company maintains reserves for potential credit
losses and such losses have been within management's expectations.

RECLASSIFICATIONS

Certain reclassifications have been made to conform prior years' data to the
current presentation. These reclassifications had no impact on previously
reported net income or stockholders' equity (deficit).

3.   New Accounting Pronouncements

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standard ("SFAS") No. 130 "Reporting Comprehensive
Income," which establishes standards for reporting and display of comprehensive
income and its components. The Company adopted the statement in 1998 and
displays comprehensive income on its consolidated statement of stockholders'
equity (deficit). The Company's comprehensive income is comprised of net income
and foreign currency translation adjustments.

In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information." SFAS No. 131 establishes standards for the
way that public companies report 


                                      F-9
<PAGE>

information about operating segments in annual financial statements and requires
reporting of selected information about operating segments in interim financial
statements issued tot he public. It also establishes standards for disclosures
regarding products and services, geographic areas and major customers. The
Company adopted the disclosure requirements for annual financial statements in
1998. The interim reporting requirements will be adopted beginning with the
Company's quarterly report on Form 10-Q for the quarter ending March 31, 1999.

In April 1998, the American Institute of Certified Public Accountants ("AICPA")
issued Statement of Position ("SOP") No. 98-5, "Reporting the Costs of Start-Up
Activities," which is effective for financial statements for fiscal years
beginning after December 15, 1998. For purposes of this SOP, start-up activities
are broadly defined as those one-time activities related to opening a new
facility, conducting business in a new territory, conducting business with a new
class of customer or beneficiary, initiating a new process in an existing
facility, or commencing some new operation. Start-up activities are also defined
to include activities related to organizing a new entity. The Company assessed
the impact and adopted SOP 98-5 as of December 31, 1998, and determined it to be
immaterial to the consolidated financial statements.

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 is required to be adopted for
fiscal years beginning after June 15, 1999 (fiscal year 2000 for the Company).
SFAS No. 133 requires that all derivative instruments be recorded on the balance
sheet at their fair value. Changes in the fair value of derivatives are to be
recorded each period in current earnings or other comprehensive income,
depending on whether a derivative is designated as part of a hedge transaction
and, if it is the type of hedge transaction. Management has not yet determined
the impact that adoption of SFAS No. 133 will have on its earnings or financial
position, but it may increase earnings volatility.

4.   Restricted Cash and Cash Equivalents

Cash and cash equivalents that are not fully available for use in operations are
classified as restricted. Restricted cash and cash equivalents relate primarily
to debt service reserve accounts required by the nonrecourse project debt
agreements for CogenAmerica Newark, CogenAmerica Parlin and CogenAmerica Morris
and to bankruptcy escrow accounts.

Restricted cash and cash equivalents consist of the following:

Depreciation expense was $8,581, $7,320, $3,626 and $7,858, for the years ended
December 31, 1998, 1997, the six months ended December 31, 1996, and the year
ended June 30, 1996, respectively.

Plant and equipment relates primarily to the Newark, Parlin, Morris and Pryor
cogeneration projects and the PWD Project standby facility.

The Newark Project consists of a 58 MW cogeneration power plant in Newark, New
Jersey which commenced operations in November 1990 and is supplying electricity
and steam pursuant to 25-year supply contracts. The Project is a qualifying
facility as defined in the Public Utility Regulatory Policies Act of 1978.

The Parlin Project consists of a 122 MW cogeneration power plant in Parlin, New
Jersey which commenced operations in June 1991 and is supplying up to 114 MW of
electricity pursuant to a 20-year electric supply contract and steam pursuant to
a 30-year supply contract. Parlin relinquished its claim to QF status and filed
rates as a public utility under the Federal Power Act. However, Parlin has been
determined to be an exempt wholesale generator (EWG). The Parlin project has
also changed from a full base load operation to a partial base load/partial
dispatchable project.

The Morris Project consists of a 117 MW cogeneration power plant in Morris,
Illinois which commenced operations in November 1998 and is supplying
electricity and steam pursuant to 25 year supply contracts. The Morris Project
is a qualifying facility as defined in the Public Utility Regulatory Policies
Act of 1978.

The Pryor Project was acquired in October 1998 and consists of a 110 MW
cogeneration power plant in Pryor, Oklahoma. The Pryor Project sells 110 MW of
capacity and varying amounts of energy to Oklahoma Gas and Electric Company
under a contract through 2007 and steam to a number of industrial users under
contracts with various termination dates ranging from 1998 and 2007. In
addition, the Pryor Project sells varying amounts of energy to the Public
Service of Oklahoma at its avoided cost. The Pryor Project is a qualifying
facility as defined in the Public Utility Regulatory Policies Act of 1978.

The PWD Project is a 22 MW standby/peak shaving facility in Philadelphia,
Pennsylvania which commenced operations in September 1993 and is supplying
electricity pursuant to 20-year supply contracts. The Company owns an 83%
interest in this project.

6.  Acquisitions and Divestitures

PRYOR PROJECT

On October 9, 1998, CogenAmerica Pryor, a wholly-owned subsidiary of
CogenAmerica, acquired from Mid Continent Power Company, L.L.C. ("MCPC") all of
the issued and outstanding stock of Oklahoma Loan Acquisition Corporation
("OLAC"), the owner of the Pryor Project. MCPC is owned 50% by NRG Energy and
50% by parties affiliated with Decker Energy International, Inc. The purchase
price was approximately $23,900, including related acquisition costs, and was
financed with borrowings from NRG Energy (See Note 10). The acquisition was
accounted for by the purchase method. Accordingly, the operating results of OLAC
have been included in the Company's consolidated financial statements since the
date of acquisition.

The following unaudited pro forma consolidated financial information assumes the
acquisition had occurred on January 1 of each year:

The pro forma consolidated results are not indicative of the actual results that
would have occurred had the acquisition been completed as of the beginning of
each period presented, nor are they necessarily indicative of results that will
be obtained in the future.

MORRIS PROJECT

On December 29, 1997, CogenAmerica Funding, a wholly-owned subsidiary of the
Company, acquired all of the issued and outstanding stock of Morris LLC from NRG
Energy for a purchase price of $5,000. At the date of acquisition, Morris LLC
had no operations, but was developing and constructing the 117 MW cogeneration
facility referred to as the Morris Project. As part of the acquisition, the
Company assumed all of the rights and obligations held by NRG Energy related to
the development, construction and financing of the Morris Project, including
those under the engineering, procurement and construction contract, the
construction and term loan agreement (see Note 10), the power purchase agreement
and various other project agreements and documents. The acquisition was
accounted for by the purchase method. The purchase price was capitalized and
included in "projects under development" on the balance sheet as of December 31,
1997. During 1998 the capitalized cost was reclassified to "other assets" and
are being amortized over the 25-year life of the Morris Project.

OES

In November 1998, the Company sold OES, a wholly-owned subsidiary of the
Company, in a stock transaction to an unrelated third party. The sales price was
$2,000 and the Company recorded a pre-tax gain of approximately $800 on the
sale.

GRAYS FERRY

CogenAmerica Schuylkill, a wholly-owned subsidiary of the Company, has a
one-third partnership interest in the Grays Ferry Partnership. The other
partners are affiliates of PECO Energy Company and Trigen Energy Corporation
("Trigen"). Grays Ferry has constructed a 150 MW cogeneration facility located
in Philadelphia which began commercial operations in January 1998. Grays Ferry
has a 25-year contract to supply all the steam produced by the project to an
affiliate of Trigen through 2022 and two 20-year contracts ("PPAs") to supply
all of the electricity produced by the project to PECO through 2017.

The Company accounts for its investment in the Grays Ferry Partnership by the
equity method. The Company's equity in earnings of the partnership was $4,758 in
1998. Grays Ferry commenced commercial operation in January 1998 and therefore
had no earnings prior to 1998. The Company and the Grays Ferry Partnership are
in litigation with PECO Energy Company over the validity of the PPAs (see Note
8).

Summarized financial information of Grays Ferry for 1998 is presented
below:

POWERENT LIMITED

PoweRent Limited ("PoweRent") is a 50% owned United Kingdom company that sells
and rents power generation equipment. The Company accounts for its investment by
the equity method. In 1997 the Company recorded a charge of $500 to reduce the
carrying value of its investment in PoweRent (see Note 14).

8.   Contingencies

In March 1998 PECO asserted that its PPAs with the Grays Ferry Partnership are
not effective based on an alleged denial of cost recovery by the Pennsylvania
Public Utility Commission. PECO claims that it is not obligated to pay the rates
set forth in the agreements. PECO has further taken the position that, in any
event, its total liability under each of the two PPAs is limited to $25,000
($50,000 in the aggregate) by the terms of such agreements. The Company and the
Grays Ferry Partnership are in litigation with PECO over its obligations under
such agreements. They are seeking actual and punitive damages plus attorneys'
fees and costs. After initially refusing to pay the rates set forth in the PPAs
and making payments for the electricity purchased from the Grays Ferry Project
at substantially lower rates, PECO was ordered by the court in which the
litigation is pending to comply with the PPAs pending the outcome 


                                      F-13
<PAGE>

of the litigation. Following the court order, PECO resumed paying under protest
the full contract rates and, as of December 31, 1998, has paid all amounts due
under the applicable PPAs. Through December 31, 1998, the Grays Ferry
Partnership has recorded revenue of approximately $34,500 from PECO, which PECO
claims it was not obligated to pay. On March 9, 1999 the court issued an order
for partial summary judgment in favor of the Grays Ferry Partnership, ruling
that PECO's attempted termination of the Grays Ferry PPAs was improper. A trial
date of March 29, 1999 has been established to determine damages owed to the
Grays Ferry Partnership and to decide the remaining litigated claims.

Due to PECO's actions, the Grays Ferry Partnership defaulted in the payment of
certain interest due under its principal credit agreement, which default has
since been cured, and the Grays Ferry Partnership continues to be in default
under other provisions of such credit agreement. As a result of such continuing
default, the lenders under the credit agreement have the ability generally to
prevent the Grays Ferry Partnership from distributing or otherwise disbursing
cash held or generated by the Grays Ferry Project. These rights, if exercised by
the lenders, could prevent the Grays Ferry Partnership from meeting its
obligations to suppliers and others and from disbursing or otherwise
distributing cash to its partners during the pendency of the litigation. Any of
these actions by the Grays Ferry Partnership's lenders could materially disrupt
the Grays Ferry Partnership's relations with its suppliers and could have other
potentially material adverse effects on its operations and profitability and,
ultimately, on the Company's earnings and financial position. While the Grays
Ferry Partnership's lenders have allowed the partnership to meet its obligations
to suppliers, the partnership received a notice of default from the lenders on
June 22, 1998, for the failure to timely convert the loan used for construction
purposes to a term loan. This failure occurred due to the event of default
created by the alleged termination of the PPAs by PECO and due to the inability
of the Grays Ferry Partnership to declare either provisional or final acceptance
of the Grays Ferry Project due to the existence of certain unresolved issues
between the Grays Ferry Partnership and Westinghouse Electric Corporation
("Westinghouse") regarding completion and testing of the Grays Ferry Project.
These issues between the partnership and Westinghouse are the subject of an
ongoing arbitration proceeding. Until there is a satisfactory resolution of the
litigation with PECO, the lenders will not allow distributions for the payment
of subordinated fees, payments to the subordinated debt lender or equity
distributions to the partners. In lieu of making these payments, the Grays Ferry
Partnership will be required to apply such amounts to the repayment of the loan.
The Company further expects that at the time the litigation is resolved the loan
will be restructured.

Although the Company does not believe it likely PECO's position ultimately will
be sustained, the Company believes that upon such event the Grays Ferry
Partnership would cease to be economically viable as currently structured and
the Company's earnings and financial position could be materially adversely
effected in various respects. Such effects could include, without limitation, a
material adjustment to the value of the Company's investment in the Grays Ferry
Project, the loss of future income and cash flows form the project and other
material costs which would not be recovered.

In January 1999 the Morris facility experienced two unscheduled outages which 
resulted in service and business interruptions to Equistar. The Company, 
Equistar and NRG Energy, as provider of construction management services and 
operation and maintenance services, are currently investigating the matter 
and are examining their respective rights and obligations with respect to 
each other and with respect to potentially responsible third parties, 
including insurers. The Company's investigation and discussions with Equistar 
are continuing. The Company does not believe that there will be a material 
adverse impact on the financial statements, however, no assurance can be 
given as to the ultimate outcome of this matter.

9.   Short-Term Borrowings

Short-term borrowings consist of amounts owed financial institutions under lines
of credit, primarily in 


                                      F-14
<PAGE>

the United Kingdom. The Company has aggregate lines of credit of approximately
$2,000 of which approximately $1,887, and $1,313 was outstanding at December 31,
1998 and 1997, respectively. The respective weighted average interest rates on
short-term borrowings as of December 31, 1998 and 1997, respectively, were
approximately 9.7% and 10.0%.

10. Long-Term Debt

Long-term debt consists of the following:

</TABLE>


Aggregate amounts of long-term debt maturing during each of the next five years
are $9,610, $33,603, $12,283, $13,689 and $12,406 in 1999, 2000, 2001, 2002 and
2003 respectively.

The credit agreements for the MeesPierson, Morris, and Newark / Parlin long-term
debt, include cross-default provisions. As a result, a default under one such
instrument or agreement could have a material adverse effect on the Company's
liquidity and capital position.

MEESPIERSON CREDIT AGREEMENT

On December 17, 1997, the Company and MeesPierson Capital Corp. entered into a
$30,000, three-year reducing, revolving credit facility (however, the Company
has agreed to not increase its borrowings above the $25,000 currently
outstanding). The $30,000 facility reduces by $2,500 on each of the first and
second anniversaries of the agreement and repayment of the outstanding balance
is due on December 17, 2000. Interest is variable based on, at the Company's
option, LIBOR plus a margin ranging from 1.50% to 1.875% or the prime rate plus
a margin ranging from 0.75% to 1.125%. The interest rate margin is dependent
upon the Company's debt service coverage ratio. The interest rate resets based
on the borrowing period selected, generally one to six months, and was 9.1875%
at December 31, 1998. The credit facility includes cross default provisions that
cause defaults to occur in the event certain defaults or other adverse events
occur under certain other instruments or agreements (including financing and
other project documents) to which the Company or one or more of its subsidiaries
or other entities in which it owns an interest is a party. The actions taken by
the power purchaser of the Grays Ferry Project have resulted in a cross default
under the MeesPierson Credit Agreement. Repayment of the MeesPierson Credit
Agreement has not been accelerated and the lender has waived such default and
the Company has agreed not to draw any additional amounts under the MeesPierson
Credit Agreement. On August 14, 1998 the lender agreed to continue the waiver on
the default until July 1, 1999 by imposing a 2.0% increase in the interest rate
effective October 1, 1998. On February 12, 1999 the lender agreed to a permanent
waiver of the Grays Ferry Project cross default and eliminated the 2.0% increase
in the interest rate effective January 1, 1999. The Company also reduced 


                                      F-15
<PAGE>

the size of the facility to $25,000. Commitment fees of 0.375% accrue on the
unused facility. Borrowings are secured by the assets, capital stock and cash
flows of the PWD Project as well as the distributable cash flows of the Newark
and Parlin Projects and the Grays Ferry Partnership, as permitted by primary
lenders of each project.

The MeesPierson Credit Agreement specifies that the Company maintain certain
covenants with which the Company is in compliance at December 31, 1998. The
Company may under certain circumstances be limited in its ability to make
restricted payments, as defined, which include dividends and certain purchases
and investments, incur additional indebtedness and engage in certain
transactions.

MORRIS PROJECT FINANCING

On September 15, 1997, Morris LLC (which was at that time an affiliate of NRG
Energy) entered into a $91,000 construction and term loan agreement (the
"Agreement") to provide nonrecourse project financing for a major portion of the
Morris Project. The Company assumed the Agreement in December 1997 upon
acquiring Morris LLC. The Agreement provides $85,600 of 20-month construction
loan commitments and $5,400 in letter of credit commitments (the "LOC
Commitment"). Upon satisfaction of all completion criteria as set forth in the
Agreement, the construction loan is due and payable or, if certain criteria are
satisfied, may be converted to a five year term loan based on a 25-year
amortization with a balloon payment at maturity. At December 31, 1998 and 1997,
$84,305 and $29,855, respectively were outstanding under the construction loan
and no amounts were pledged under the LOC Commitment. Interest on the
construction loan is variable based on, at the Company's option, either the base
rate, as defined in the Agreement, or LIBOR plus 0.75%. The interest rate resets
based on the Company's selection of the borrowing period ranging from one to six
months. The interest rate was 6.0% at December 31, 1998. Borrowings are secured
by CogenAmerica Funding's ownership interest in Morris LLC, its cash flows,
dividends and any other property that CogenAmerica Funding may be entitled to as
owner of Morris LLC.

The Agreement specifies that the Company maintain certain covenants with which
the Company is in compliance at December 31, 1998. The Company may under certain
circumstances be limited in its ability to make restricted payments, as defined,
which include dividends and certain purchases and investments, incur additional
indebtedness and engage in certain transactions. 

NEWARK AND PARLIN FINANCING

On May 17, 1996, CogenAmerica Newark and CogenAmerica Parlin entered into the
Newark and Parlin Credit Agreement with provisions for a $155,000 fifteen-year
nonrecourse term loan and a $5,000 five-year debt service reserve line of
credit. On May 23, 1996, CogenAmerica Newark borrowed $60,000 in the form of a
temporary term loan under the Newark and Parlin Credit Agreement. On July 11,
1996, an additional $95,000 was borrowed and the aggregate borrowings were
converted into a $155,000 fifteen-year nonrecourse term loan (the "Term Loan")
which is a joint and several liability of CogenAmerica Newark and CogenAmerica
Parlin. The Term Loan is amortized by quarterly principal payments ranging from
1.275% to 1.825% through the fourteenth year and 3.075% in the fifteenth year.

The interest rate on the outstanding principal is variable based on, at the
Company's option, LIBOR plus a 1.125% margin or a defined base rate plus a
0.375% margin. For any quarterly period where the debt service coverage ratio is
in excess of 1.4:1, both margins are reduced by 0.125%. The interest rate resets
based on the borrowing period selected, generally one to three months. The
interest rate was 6.3125% at December 31, 1998. Nominal margin increases for
both the LIBOR and the defined base rate will occur in year six and eleven of
the Newark and Parlin Credit Agreement. Upon entering into 


                                      F-16
<PAGE>

the Newark and Parlin Credit Agreement, CogenAmerica Newark and CogenAmerica
Parlin entered into an interest rate swap agreement with the lender which fixes
the interest rate on 50% of the principal amount outstanding under the Term Loan
at 6.9% plus the margin in effect as described above.

No amounts were outstanding on the debt service reserve line of credit at
December 31, 1998 and 1997. The line carries a commitment fee of 1.125% on the
undrawn amount. CogenAmerica Newark and CogenAmerica Parlin are required to
maintain debt service reserve accounts with the lender to provide for future
debt service, capital improvements and major maintenance. At December 31, 1998
and 1997 these balances totaled $11,249 and $7,757, respectively, and earned
interest at 3.25%. These balances are recorded as restricted cash and cash
equivalents in the accompanying financial statements.

The Term Loan is secured by all CogenAmerica Newark and CogenAmerica Parlin
assets and a pledge of CogenAmerica Newark's and CogenAmerica Parlin's capital
stock. CogenAmerica has guaranteed repayment of up to $25,000 of the Term Loan
based on the principal balance of the loan, and also guaranteed payment by
CogenAmerica Newark and CogenAmerica Parlin of all income and franchise taxes
when due. The Company's guarantee is reduced proportionate to the outstanding
principal as payments are made on the debt. The balance of this guarantee was
$21,775 as of December 31, 1998. As an inducement to obtain the $60,000
temporary term loan, effective May 23, 1996, NRG Energy guaranteed payment of
pre-existing liabilities of CogenAmerica Newark and CogenAmerica Parlin up to
$5,000. The maximum guarantee is reduced as certain defined milestones are
reached and eliminated no later than May 23, 2001. At December 31, 1998, the
guarantee amount was $3,000.

The Newark and Parlin Credit Agreement specifies that the Company maintain
certain covenants with which the Company is in compliance at December 31, 1998.
The Company may under certain circumstances be limited in its ability to make
restricted payments, as defined, which include dividends and certain purchases
and investments, incur additional indebtedness and engage in certain
transactions.

2001, 2002 and 2003, respectively. Interest expense related to loans due NRG
Energy was $1,249, $1,327, $648 and $1,098 for the years ended December 31, 1998

MORRIS NOTE

In connection with its acquisition of the Morris Project, CogenAmerica 
Funding, a wholly-owned subsidiary of the Company, assumed all of the 
obligations of NRG Energy to provide future equity contributions to the 
project, which obligations are limited ot the lesser of 20% of the total 
project cost or $22,000. NRG Energy has guaranteed to the Morris Project's 
lenders that CogenAmerica Funding will make these future equity 
contributions, and the Company has guaranteed to NRG Energy the obligation of 
CogenAmerica Funding to make these future equity contributions (which 
guarantee is secured by a second priority lien on the Company's interest in 
the Morris Project). In addition, NRG Energy has committed in a Supplemental 
Loan Agreement between the Company, CogenAmerica Funding and NRG Energy to 
loan CogenAmerica Funding and the Company (as co-borrowers) the full amount 
of such equity contributions by CogenAmerica Funding, subject to certain 
conditions precedent, at CogenAmerica Funding's option. Any such loan will be 
secured by a second priority lien on all of the membership interests of the 
project and will be recourse to CogenAmerica Funding and the Company. 
Effective November 30, 1998 the Company and NRG Energy agreed to a First 
Amendment to Supplemental Loan Agreement that allowed the Company to 
contribute the $22,000 of equity in installments to match the construction 
draw payments. At December 31, 1998, $12,027 had been drawn and contributed 
as equity. Subsequent to year end additional draws and equity fundings have 
been made and as of March 26, 1999, the entire $22,000 had been drawn and 
contributed as equity. The Supplemental Loan Agreement calls for an interest 
rate of prime plus 1.5%. Effective with the First Amendment the interest rate 
was increased to prime plus 3.5% pending elimination of the possible event of 
default under the MeesPierson Credit Agreement related to the Grays Ferry 
Project. On February 23, 1999 the Company reached agreement with NRG Energy 
that the possible event of default under the MeesPierson Credit Agreement had 
been eliminated. As a result, NRG Energy reduced the interest rate by 2% 
effective as of January 1, 1999.

PRYOR NOTE

On September 30, 1998, NRG Energy loaned the Company and CogenAmerica Pryor 
$23,947 to finance the acquisition of the Pryor Project. The loan is a 
six-year term facility calling for principal and interest payments on a 
quarterly basis, based on project cash flows. The interest rate on the note 
was set at prime plus 3.5%, reducing by 2% upon elimination of the possible 
event of default under the MeesPierson Credit Agreement related to the Grays 
Ferry Project. On February 23, 1999 the Company reached agreement with NRG 
Energy that the possible event of default under the 

                                      F-18
<PAGE>

MeesPierson Credit Agreement had been eliminated. As a result, NRG Energy
reduced the interest rate by 2% effective as of January 1, 1999.

12.  Stockholders' Equity

NRG ENERGY STOCK OPTION

During 1997 NRG Energy made loans aggregating $10,000 to CogenAmerica Schuylkill
to provide funding for CogenAmerica Schuylkill's equity contribution obligation
to Grays Ferry. Pursuant to a stock option right approved by the bankruptcy
court and included in the loan commitment agreement, in October 1997 NRG Energy
converted $3,000 of the borrowings into 396,255 shares of the Company's common
stock. Following exercise of the option, NRG Energy's ownership interest in the
Company increased to 45.21%.

EARNINGS PER SHARE

Basic earnings per share ("EPS") includes no dilution and is computed by
dividing net income (loss) by the weighted average shares of common stock
outstanding. Diluted EPS is computed by dividing net income (loss) by the
weighted average shares of common stock and dilutive common stock equivalents
outstanding. The Company's dilutive common stock equivalents result from stock
options and are computed using the treasury stock method. The following table
reconciles the numerators and denominators of the basic and diluted EPS
computations for the years ended December 31, 1998 and 1997, and the six months
ended December 31, 1996. The dilutive stock options became outstanding
subsequent to June 30, 1996. Accordingly, there was no difference in basic and
diluted EPS for the year ended June 30, 1996.

Options to purchase 147,000 shares of common stock at prices ranging from $11.58
- - $18.38 were outstanding at December 31, 1998 but were not included in the 1998
computation of diluted EPS because the options' exercise price was greater than
the average market price of the common shares.

STOCK OPTIONS

The Company has reserved 1,000,000 shares of common stock for issuance under its
1996, 1997 and 1998 stock option plans. The plans provide for nonqualified and
incentive stock options to be granted to directors, officers, key employees and
others who make a significant contribution to the Company as determined by the
Board at an exercise price not less than the fair market value of the common
stock at the date of grant. An option will generally expire ten years after the
date it is granted and will ordinarily become exercisable as to one third of the
shares subject to the option on each of the first three anniversaries of the
grant. Following a "change of control" all options granted under the stock
option plans may become immediately exercisable.

To improve liquidity, in fiscal 1994 the Company initiated efforts to liquidate
specific power generation equipment that was not in use in an operating project,
rented to a customer or critical to the completion of projects in development.
These assets, consisting mainly of gas and steam turbines, were written down in
fiscal 1994 and 1995 to liquidation values determined by independent appraisal,
reclassified on the balance sheet as "equipment held for sale" and no longer
depreciated. The $3,228 carrying value of the equipment at June 30, 1995 was
reduced to $2,628 and $1,598 at December 31, 1996 and September 30, 1997,
respectively, through periodic sales. In the 1997 fourth quarter, the remaining
equipment included in the balance sheet caption "equipment held for sale" was
scrapped due to lack of interest by potential buyers, resulting in an impairment
charge of $1,553.


                                      F-21
<PAGE>

Impairment charges for property, plant and equipment disposals totaled $1,801,
comprised of losses of $779 from disposal of other power generating equipment,
and write-offs of $1,023 for equipment that was determined to be non-useable or
could not be located during asset counts and inspections performed at OES and
the PWD Project.

The asset impairment charge also included $371 to write-off capitalized project
development costs related to certain development projects that were terminated.

During the 1997 fourth quarter, the Company completed a thorough review of its
business operations and market opportunities to determine whether operations of
the PWD Project and the equipment sales, rental and service businesses should be
continued. The board of directors determined that the PWD Project should be
retained and that the equipment sales, rental and service segment should be
exited.

The equipment sales, rental and service segment has not been reported as a
discontinued operation because of uncertainties about the expected timing and
manner of disposal. However, management performed an impairment review of the
segment's long-lived assets as required by SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of".
Based on an analysis of estimated future cash flows, the carrying value of OES'
generator equipment was determined to be impaired. Consequently, a provision of
$976 was recorded to write-down the assets to their estimated fair value as
determined by management based on sales values of similar equipment.

Management also evaluated the carrying value of its 50% investment in PoweRent.
Due to PoweRent's low earnings capacity, combined with the expectation of
exiting this business in the near term, the investment was determined to be
permanently impaired. The carrying value of the investment was written down by
$500 based on discussions with potential buyers and management's estimate of the
investment value.

During the year ended June 30, 1996 unrecoverable project development costs of
$180 were written off.

</TABLE>


The Company has $52,875 of state and local net operating loss carryforwards
available to offset future years' state and local taxable income. These
carryforwards will expire starting in 1999 and will continue to expire through
2012. The Company also has foreign net operating loss carryforwards of



                                      F-24
<PAGE>

approximately $2,051. The net operating loss carryforward for alternative
minimum tax purposes is approximately $23,621 at December 31, 1998.

A valuation allowance was recorded in prior years to reserve primarily for
deferred tax assets that were not expected to be recovered through future
reversal of existing temporary differences. In management's judgment,
realization of the reserved tax benefits did not meet the "more likely than not"
recognition criteria of SFAS No. 109 due to the Company's history of operating
losses and projections of future taxable income. At December 31, 1997, the
valuation allowance was reduced to $7,230 based on management's evaluation of
the weight of available evidence about the likelihood of realizing the deferred
tax assets. Positive factors contributing to the decision to reduce the
valuation allowance included the sustained period of profitability since
emergence from bankruptcy and improved outlooks for future earnings. The
remaining valuation allowance at December 31, 1998 reserves a portion of the
state operating loss carryforwards and certain other temporary differences and
all of the investment tax credit, capital loss, and foreign operating loss
carryforwards.

Under the Plan, NRG Energy acquired a 41.86% equity interest in the Company.
This acquisition, along with other shifts in shareholders' stock holdings,
amounted to a more than 50% change in ownership in the Company over a three year
period. Under the general net operating loss and tax credit carryover rules,
utilization of these losses and tax credits would be limited. However, the
Internal Revenue Code provides an exception to the general rules for loss
corporations that undergo an ownership change by reason of certain bankruptcy
proceedings. The Company believes it qualifies for the bankruptcy exception and
its net operating loss and tax credit carryforwards are not subject to the
change of ownership limitations. The bankruptcy exception rules also provide
that if a subsequent ownership change should occur within the two years
following the bankruptcy-protected change, the benefits of the bankruptcy
exception will be lost and the Company's net operating loss and tax credit
carryforwards will be effectively eliminated. During the year ended of December
31, 1998, the Company did not undergo a subsequent ownership change in the two
year period following the bankruptcy protected change.

Revenues from one energy customer accounted for 50%, 57%, 46% and 62% for the
years ended December 31, 1998 and 1997, the six months ended December 31, 1996,
and the year ended June 30, 1996, respectively.

19.  Minority Interest

OPCI, a subsidiary of the Company, is 17% owned by an unrelated private
investor. OPCI is required to make quarterly distributions to the minority owner
of 17% of its net earnings. These distributions totaled $247, $244, $125 and
$227 for the years ended December 31, 1998 and 1997, the six months ended
December 31, 1996, and fiscal 1996, respectively, and are recorded as interest
expense in the consolidated statement of operations. The 17% minority interest
is redeemable by the Company at its option for a price equal to 17% of the
present value of the projected income stream of OPCI. The Company is obligated
upon certain events of default to redeem the minority interest at 60% of the
Company's redemption price. The Company's redemption price at December 31, 1998
was approximately $2,400. There are currently no events of default.

    DECEMBER 31, 1998 AND 1997 AND
    INDEPENDENT AUDITORS' REPORT

INDEPENDENT AUDITORS' REPORT


To the Partners of Grays Ferry Cogeneration Partnership:

We have audited the accompanying balance sheets of Grays Ferry Cogeneration
Partnership (the "Partnership"), as of December 31, 1998 and 1997, and the
related statements of changes in partners' capital, and cash flows for the years
then ended, and the related statement of income for the period from January 9,
1998 (date of commercial operation) to December 31, 1998. These financial
statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Partnership as of December 31, 1998 and
1997, and its cash flows for the years then ended, and the results of its
operations for the period from January 9, 1998 (date of commercial operation) to
December 31, 1998 in conformity with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Partnership will continue as a going concern. As discussed in Note 2 to the
financial statements, PECO Energy has taken action to terminate its power
purchase agreements with the Partnership. As a consequence, the Project Lender
has determined that the Partnership is in default. These actions raise
substantial doubt about the Partnership's ability to continue as a going
concern. Management's plans concerning these matters are also discussed in Note
2. The financial statements do not include any adjustment that might result from
the outcome of these uncertainties, other than the classification of the Project
debt as current.

GRAYS FERRY COGENERATION PARTNERSHIP

NOTES TO FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1998 AND 1997
- --------------------------------------------------------------------------------


1.    ORGANIZATION OF PARTNERSHIP

      Grays Ferry Cogeneration Partnership, (the "Partnership") was organized on
      October 29, 1991 as a Pennsylvania general partnership for the sole
      purpose of developing, owning, constructing and operating a 150 megawatt
      gas and oil fired qualifying cogeneration facility (the "Project") at the
      Schuylkill Station of the Trigen-Philadelphia Energy Corporation ("TPEC")
      in Philadelphia, Pennsylvania. For the period from October 29, 1991 (date
      of inception) through January 8, 1998, the Partnership was considered a
      development stage entity as its sole activity was construction of the
      Facility. Pursuant to 20-year electricity and 25-year steam purchase
      agreements between the Partnership and its two customers, sales of
      electricity and steam began in January 9, 1998, the date of Commercial
      Operation.

      The Partnership's date of Commercial Operation of January 9, 1998 was
      chosen because it was the date its customers started paying it for
      electricity and steam sold to them under its 20-year electricity purchase
      agreements and its 25-year steam purchase agreements. The Partnership
      believes the date should have been December 30, 1997 and is litigating
      this issue as part of the litigation described in Note 2.

      The Partnership's original general partners are Adwin Equipment Company, a
      wholly owned subsidiary of Eastern Pennsylvania Development Company, which
      is a wholly owned subsidiary of PECO Energy Company ("PECO") and O'Brien
      (Schuylkill) Cogeneration, Inc., ("O'Brien"), a wholly owned subsidiary of
      O'Brien Environmental Energy, Inc. Subsequent to the original Partnership
      formation, Adwin (Schuylkill) Cogeneration, Inc. ("Adwin"), a wholly owned
      subsidiary of Adwin Equipment Company, was assigned all rights,
      responsibilities, and obligations of the Partnership previously held by
      Adwin Equipment Company.

      Trigen (Schuylkill) Cogeneration, Inc. ("Trigen"), a wholly owned
      subsidiary of Trigen Energy Corporation and an affiliate of TPEC,
      Philadelphia Thermal Development Corporation, ("PTDC"), and Philadelphia
      United Power Corporation, ("PUPCO"), joined the Partnership as an equal
      partner as of March 1, 1996.

      In a reorganization plan, approximately 40% of the capital stock of
      O'Brien Environmental Energy, Inc. was acquired by NRG Energy, Inc.,
      and the Company was renamed NRG Generating (U.S.) Inc. As a result of
      this reorganization, O'Brien became known as NRGG (Schuylkill)
      Cogeneration, Inc. ("NRGG"). During 1998, NRGG was renamed
      CogenAmerica Schuylkill, Inc. ("Cogen").

      The three general partners are equal partners, with net operating profits
      and losses and distributions to be allocated equally to the partners,
      subject to the terms and provisions as stated in the Amended and Restated
      Partnership Agreement.

2.    CONTINUATION OF BUSINESS

      The accompanying financial statements have been prepared assuming that the
      Partnership will continue as a going concern. As discussed below, PECO has
      taken action to terminate its power purchase agreements with the
      Partnership. As a consequence, the Project Lender has determined that the



                                       -6-

<PAGE>

      Partnership is in default. These actions raise substantial doubt about the
      Partnership's ability to continue as a going concern. The financial
      statements do not include any adjustment that might result from the
      outcome of these uncertainties, other than the classification of the
      Project debt as current.

      ENGINEERING, PROCUREMENT AND CONSTRUCTION CONTRACT - Although the
      Partnership began Commercial Operation on January 9, 1998, the Partnership
      has not yet accepted care, custody or control of the Project from
      Westinghouse Electric Corporation (the "Contractor") due to the
      Partnership's concerns over design and construction issues. This issue is
      in arbitration.

      PECO - In March 1998, the Partnership received notice from PECO that PECO
      believes its power purchase agreements with the Partnership are no longer
      effective. PECO has refused to pay the rates set forth in the agreements
      based on its allegations that the Pennsylvania Public Utilities Commission
      (the "PPUC") has denied cost recovery of the power purchase agreements in
      retail electric rates.

      On March 9, 1998, the Partnership, along with Trigen, NRGG and TPEC
      (collectively "Plaintiffs") filed suit against PECO, Adwin and the PPUC
      (collectively "Defendants") in United States District Court for the
      District of Pennsylvania. The suit sought to enjoin PECO from terminating
      the power purchase agreements and to compel PECO to pay the rates set
      forth in the agreements. In addition, the Plaintiffs sought actual
      damages, punitive damages, attorneys' fees and costs. On March 19, 1998,
      the federal district court dismissed the lawsuit for lack of subject
      matter jurisdiction.

      On April 9, 1998, the Plaintiffs filed suit against the Defendants in the
      Court of Common Pleas (the "Court") for Philadelphia County in the State
      of Pennsylvania. Preliminary injunctive relief against PECO in the form of
      specific performance of the electric sale agreements, including payments
      according to the contract terms, was granted by the Court on May 6, 1998.
      A $50,000 bond required by the Court was posted by the Plaintiffs on May
      7, 1998. On May 8, 1998, PECO sought a stay of the May 6 Order which was
      denied on May 20, 1998. Also on May 20, 1998, the Court issued a separate
      order adjudging PECO to be in civil contempt of the May 6 Order. A
      coercive sanction of $50,000 per day, or portion thereof, for nonpayment
      of all sums owing by PECO in accordance to the contract terms was included
      in the May 20, 1998 Order. An emergency application of stay by PECO of the
      May 6 Order was denied on May 22, 1998. As a result, PECO complied with
      the May 6 Order on May 22, 1998.

      CONSTRUCTION LOAN DEFAULT - On March 17, 1998 the Partnership received a
      notice of default from the Project Lender stating that PECO's
      determination that the power purchase agreements are no longer in effect
      constitutes a Material Adverse Effect as defined under the credit
      agreement. In addition, the Subordinate Credit Commitment (the
      "Subordinate Debt") contains cross-default provisions; accordingly upon
      notice of default from the Project Lender, the Partnership was in default
      on its Subordinate Debt. As of the date of this report, the default has
      not been waived; accordingly, the Partnership's long-term debt has been
      reclassified as current in the Partnership's balance sheet (see Note 6).
      The Project Lender has also restricted the Partnership's ability to make
      distributions to related parties for certain transactions, along with
      distributions to the Partners of Partnership earnings. In addition, the
      interest rate charged under the credit agreement increased to prime plus
      2.00%, and the interest on the Subordinate Debt increased to prime plus
      3.5% (9.75% and 11.25%, respectively, at December 31, 1998), the penalty
      interest rates.

      Management intends to vigorously pursue enforcement of the power purchase
      agreements, which if successful, should result in a cure of the
      construction loan and Subordinate Debt default.

3.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     (a)  CAPITALIZED PROJECT COSTS - Construction of the Project was originally
          scheduled to be completed on or about December 8, 1997 (see Notes 1
          and 5), at an estimated cost of $158,000,000. $128,000,000 was
          provided from the proceeds of the credit agreements (see Note 6), and
          $30,000,000 was provided from partners' capital contributions (see
          Note 7). The remainder has been financed through accounts and
          retainage payable. Capitalized Project costs include costs incurred in
          the development and construction of the gas and oil fired 150-megawatt
          cogeneration facility. The majority of these costs represent
          expenditures made under the Engineering, Procurement, and Construction
          contract between the Partnership and the Contractor. Other costs
          represent expenditures for legal, consulting, engineering and
          financing activities relating to the Project. All costs related to the
          design and construction of the Project up to the date of Commercial
          Operation on January 9, 1998, have been capitalized as construction
          work-in-progress when incurred and now are classified as plant in
          service, except deferred financing fees which are included in other
          assets.

          Substantially all of the property, plant and equipment is being
          depreciated over 20 years, the life of the Project's electric and
          contingent capacity sales agreements (see Note 4).

     (b)  REVENUE RECOGNITION - The Partnership's primary source of revenues is
          from the sale of steam to TPEC and the sale of electricity generated
          by the Project to PECO. Pursuant to the Steam Sales Agreement, TPEC is
          obligated to purchase all of its steam requirements from the Project
          as defined in the agreement. Under the provisions of the Power
          Purchase Agreements, PECO has agreed to purchase, or accept delivery
          of, the net electric output from the Project, up to the lesser of 150
          megawatts or the amount of electric output for which the Federal
          Energy Regulatory Commission ("FERC") has certified the Project.

     (c)  SEGMENT REPORTING - The Partnership currently operates the Project,
          which produces two forms of salable energy from one generation
          process. Revenues from each of the two forms are disclosed on the
          statement of income.

     (d)  INVENTORY - Inventory, which is recorded on the first-in, first-out
          basis, consists of the following at December 31:

</TABLE>


     (e)  FAIR VALUE OF FINANCIAL INSTRUMENTS - The amounts reported in the
          balance sheets for accounts receivable, accounts payable and debt
          approximate fair value.

     (f)  ACCOUNTING FOR INCOME TAXES - The Partnership is not a taxpaying
          entity for income tax purposes. Taxable income or loss from the
          Partnership is reportable by the Partners on their respective income
          tax returns. Accordingly, there is no recognition of income taxes in
          the financial statements.

     (g)  INTEREST RATE HEDGING - The Partnership entered into interest rate
          swap agreements in order to hedge against future increases in interest
          rates. For swap contracts that effectively hedge interest 



                                       -8-

<PAGE>

            rate exposures, the net cash amounts paid or received on the
            contract are accrued and recognized as an adjustment to interest
            expense over the period of the contract.

      (h)   USE OF ESTIMATES - The preparation of the Partnership's financial
            statements in conformity with generally accepted accounting
            principles necessarily requires management to make estimates and
            assumptions that affect the reported amounts of assets and
            liabilities and disclosure of contingent assets and liabilities at
            the balance sheet dates and the amounts of expenses during the
            reporting periods. Actual results could differ from those estimates.

      (i)   RECLASSIFICATIONS - Certain amounts in the 1997 financial statements
            have been reclassified to conform to current year presentation.

      (j)   CASH AND CASH EQUIVALENTS - The Partnership classifies all
            investments with terms to maturity of less than three months upon
            purchase as cash and cash equivalents. Cash and cash equivalents at
            December 31, 1998 consist primarily of a money market investment
            account, which is carried at market, which approximates cost.

      (k)   DEFERRED FINANCING COSTS - Deferred financing costs of $6,544,596
            are amortized over the life of the credit agreements and are
            included in other assets.

      (l)   REAL ESTATE TAXES - The Partnership has accrued real estate taxes as
            required in the Facility Lease (see Note 4). The Partnership has
            made its best estimate of its anticipated real estate taxes, but has
            not yet been billed by its local taxing authority. However,
            management does not believe that actual taxes due will be materially
            different than the amounts currently accrued.

4.    RELATED PARTY AGREEMENTS AND TRANSACTIONS

      FACILITY LEASE - The Project is located at 2600 Christian Street,
      Philadelphia, Pennsylvania, on the site of TPEC's Schuylkill Station and
      PECO's Schuylkill Station, which is owned by PECO. The Partnership has
      leased a portion of the land which TPEC has leased from PECO. The lease
      agreement with TPEC commenced on the date construction began, March 8,
      1996, and will terminate 25 years from the date of Commercial Operation.
      The Partnership is obligated to pay TPEC $1 per year as rent. The
      Partnership is required to pay any increase in taxes, assessments and fees
      assessed against the site or the Facility during the lease term.

      DOCK FACILITY SERVICE AGREEMENT - The Partnership has an agreement with
      PTDC and TPEC, an affiliate of PTDC, for fuel oil transportation and
      storage services. The Partnership pays operating fees based on the number
      of barrels received at, or delivered to, the dock as well as a storage fee
      for barrels stored for use by the Project. These fees are adjusted
      annually based on the Consumer Price Index ("CPI"). During 1998 and 1997,
      the Partnership incurred costs associated with these services of $199,640
      and $100,923, respectively, of which $12,862 and $100,923 is included in
      accounts payable at December 31, 1998 and 1997, respectively. The entrance
      to the Schuylkill Station of TPEC, which is also the entrance to the
      Project, was upgraded in 1997. The Partnership had previously agreed to
      reimburse TPEC for its share of the cost which amounted to $250,000.

      OPERATIONS AND MAINTENANCE AGREEMENT - PUPCO, a Delaware corporation, an
      affiliate of TPEC, manages and performs all operation and maintenance of
      the Project subsequent to the Commercial Operation date in accordance with
      a 25-year agreement. Prior to Commercial Operation, PUPCO was reimbursed
      for certain costs incurred during mobilization and received a monthly fee
      of $25,000 limited to $150,000 in total monthly fees. After Commercial
      Operation begins, the Partnership is required to pay PUPCO an annual
      operating fee of $600,000 as detailed in the agreement. A portion of the


                                       -9-

<PAGE>

      operating fee, $400,000, is adjusted annually based on changes in the CPI.
      As an additional fee, PUPCO will receive 30% of all payments received by
      the Partnership pursuant to the Contingent Capacity Purchase Addendum
      (Phase 1). The Partnership was billed by PUPCO annual operating fees of
      $600,000 and a capacity fee of $757,416, and reimbursable expenses of
      $1,647,658 for 1998, of which $1,497,003 was included in accounts payable
      at December 31, 1998. Included in those billings were $29,192 and $32,851
      of fees and reimbursable expenses, respectively, which were capitalized as
      construction cost.

      STEAM SALE AGREEMENT - The Partnership has a 25-year agreement with TPEC
      in which the Partnership sells all of the steam produced by the plant to
      TPEC. The price for low- and high-pressure steam is determined based on a
      function of weighted average fuel price, CPI and the City of Philadelphia
      Tariff Water and Sewer Rates. The agreement requires TPEC to pay for a
      minimum of 3.3 Mlbs on an annual basis upon Commercial Operation. During
      1998 and 1997, $18,113,962 and $851,182, respectively, was billed by the
      Partnership to TPEC for steam produced and capacity charges. Of the
      amounts billed in 1998 and 1997, $296,199 and $851,182, respectively, were
      capitalized as a reduction of construction costs as such sales occurred as
      a result of plant testing. Accounts receivable as of December 31, 1998 and
      1997 include $3,985,346 and $851,182, respectively, due from TPEC for
      these billings.

      ELECTRIC AND CONTINGENT CAPACITY SALES AGREEMENTS - The Partnership has
      two 20-year electric sale agreements with PECO, commencing at the
      Commercial Operation date, whereby the Partnership supplies PECO with
      electric output at costs defined by the agreements. The terms of
      agreements require PECO to purchase or accept delivery of the net electric
      output from the power plant of the lesser of 150 megawatts or the amount
      of electric output for which the FERC has certified the power plant. The
      two parties also entered into a 20-year Contingent Capacity Purchase
      Addendum which requires PECO to purchase electric capacity from the
      Partnership. The addendum term commenced on the date of Commercial
      Operation. During 1998 and 1997, $61,932,981 and $1,778,911, respectively,
      was billed by the Partnership to PECO for electricity produced and
      capacity charges. Of the amounts billed in 1998 and 1997, $1,624,855 and
      $1,778,911, respectively, were applied as a reduction of construction
      costs as such sales occurred as a result of plant testing. Accounts
      receivable as of December 31, 1998 and 1997 include $6,693,424 and
      $1,778,911, respectively, due from PECO for these billings. As a result of
      the Project, PECO was required to construct an interconnection between its
      facility and the Partnership's facility. The costs associated with the
      interconnection, $2,355,426, were reimbursed to PECO by the Partnership
      during 1997. Other amounts paid to PECO during 1997 for reimbursement of
      expenses were $6,000 for the Partnership's portion of a joint thermal
      modeling study.

      STEAM VENTURE AGREEMENT - On September 17, 1993, TPEC, PUPCO and the
      Partnership entered into an Amended and Restated Steam Venture Agreement
      for the purpose of the Partnership designing, constructing, starting-up,
      and testing and owning a cogeneration facility, with the assistance of the
      other two participants. The agreement required the Partnership to pay
      PUPCO quarterly fees of $150,000 up to Commercial Operation. Amounts
      billed in 1997 were capitalized as construction costs; however, $252,635
      was in accounts payable at December 31, 1997. After Commercial Operation
      commenced, PUPCO receives annual fees of $1,200,000 payable in monthly
      installments. Two-thirds of the annual fee is subject to an escalation of
      3% per annum. During 1998 the Partnership was billed $1,200,000 by PUPCO
      under this agreement, of which $25,806 was capitalized as construction
      cost. Accounts payable at December 31, 1998, include $1,200,000 related to
      these billings. In addition, during 1997, the Partnership incurred PUPCO
      mobilization fees of $150,000.

      FUEL MANAGEMENT AGREEMENT - During 1998, the Partnership had an agreement
      with Exelon Corporation, a subsidiary of PECO, for fuel management
      services. Under the terms of the agreement, the Partnership was to pay
      Exelon a fee based on the amount of natural gas and liquid fuels delivered
      to 


                                       -10-

      the Project. During 1998, the Partnership incurred costs associated with
      these services of $176,480, of which $4,474 was capitalized as 
      construction costs and $176,480 was included in accounts payable at 
      December 31, 1998.

      CONSTRUCTION MANAGEMENT - NRGG received fees and reimbursed expenses for
      management services provided to the Project and for acting as the
      Partnership's representative to administer all third-party contracts
      during the construction phase. The arrangement commenced on March 8, 1996
      and ceased upon Commercial Operation. During 1998, NRGG billed the
      Partnership fees and reimbursed expenses of $56,250 and $214,795,
      respectively, all of which was capitalized as construction cost. Accounts
      payable at December 31, 1997 included $205,201 of such fees and expenses.

      MANAGEMENT SERVICES AND OTHER - In accordance with the Partnership
      agreement, the Partnership is required to pay it's Managing Partner
      $150,000 per year for providing management services to the Partnership.
      NRGG acted as Managing Partner through November 15, 1998 and billed the
      Partnership fees and reimbursable expenses of $131,250 and $36,719,
      respectively of which $118,750 was included in accounts payable at
      December 31, 1998. Of these fees, $3,387 was capitalized as construction
      cost. Effective November 15, 1998, Trigen became the Managing Partner and
      billed the Partnership fees of $18,750 for the year ended December 31,
      1998, all of which was included in accounts payable as of December 31,
      1998. In addition, the Partnership purchases demineralized water from
      Trigen. For the year ended December 31, 1998, the Partnership purchased
      $2,206,869 of demineralized water from Trigen of which $46,671 was
      capitalized as a construction cost prior to commercial operation and
      $498,322 was included in accounts payable as of December 31, 1998.

5.    OTHER SIGNIFICANT CONTRACTS

      GAS SUPPLY AGREEMENT - The Partnership has a Gas Sales Agreement with
      Aquila Energy Marketing Corporation ("Aquila"), a Delaware corporation,
      providing for the purchase of natural gas to meet the power plant's
      requirements. The purchase of gas as stated in the agreement is divided
      into two tiers based on quantity purchased. The price of the first tier,
      for daily purchases up to 32,000 million British Thermal units (MMBtu) is
      based on the gas spot market plus a premium. The second tier, for daily
      purchases above the initial 32,000 MMBtu, is also based on the gas spot
      market plus a premium. The premium on second tier gas purchases is subject
      to annual negotiations effective for years beginning January 1, 1999 and
      after. In addition, beginning in 2001 the price of both tiers is indexed
      based on the electricity rate received by the Project. The agreement also
      has a pricing provision for winter quantity gas delivered to certain
      redelivery points as defined in the agreement. The initial term of the Gas
      Sales Agreement is 192 months from the initial delivery and may be
      extended for one-year renewal periods unless terminated by either party.
      During 1998, the Partnership purchased $14,691,090 of gas under this
      agreement.

      GAS TRANSPORTATION ARRANGEMENTS - The Partnership and the Philadelphia
      Authority for Industrial Development ("PAID") entered into a Service
      Agreement dated January 28, 1996, whereby PAID agreed to deliver
      non-interruptible local gas service to the Project for up to 50,000
      Dekatherms ("Dth") per day from the date of Commercial Operation via an
      established agreement with Philadelphia Gas Works ("PGW"). The agreement
      between the Partnership and PAID is for a period of 25 years and may be
      extended at the mutual agreement of the two parties. The Partnership is
      committed to purchase transportation services for a minimum annual
      quantity based in part, on steam sales to Trigen. In addition, TPEC
      permanently released capacity of 15,000 Dth to the Partnership beginning
      November 1, 1997. TPEC retained first refusal privileges on this released
      capacity in the event that the Partnership does not require the additional
      capacity. During 1998, the Partnership purchased $3,187,640 of
      transportation services under these agreements.



                                       -11-

      ENGINEERING, PROCUREMENT AND CONSTRUCTION CONTRACT - The Partnership has a
      $116,300,000 engineering, procurement and construction contract (the
      "EPC") with the Contractor. The contract guaranteed that the Project would
      be provisionally completed by December 8, 1997, the projected date of
      Commercial Operation. Provisions of the contract included rebates to the
      Partnership of $70,000 a day should the Contractor fail to complete the
      Project on schedule as well as bonus payments to the Contractor should the
      Project be completed prior to schedule. The contract was not completed on
      time. As such, a rebate in the amount of $1,722,000 has been recorded in
      accounts receivable at December 31, 1998. The Partnership believes this
      accrual is based on a conservative estimate. Currently, the Partnership
      and the Contractor are in arbitration over the completion of the EPC
      contract (see Note 2). Provisional acceptance of the Project has not yet
      occurred.

      COMBUSTION TURBINE PARTS SUPPLY AND REPAIR AND SCHEDULED OUTAGE SERVICES
      AGREEMENT - The Partnership entered into a combustion turbine parts supply
      and repair and scheduled outage services agreement with Westinghouse
      Electric Corporation as of August 29, 1997. The agreement requires the
      Partnership to purchase from the Contractor parts and miscellaneous
      hardware for the gas turbine comprising a portion of the Project, repair
      of parts for the gas turbine comprising a portion of the Project, and
      scheduled outage services and technical field assistance for unscheduled
      outages as defined in the agreement.

6.    CREDIT AGREEMENTS

      On March 1, 1996 the Partnership entered into a $125,000,000 Credit
      Agreement (the "Agreement") to provide construction and term loan
      financing for the purpose of financing a major portion of the Project
      facility. The Agreement provides the Partnership with $113,000,000 of
      construction loan commitments (the "Construction Loan") which are
      convertible to term loan commitments (the "Term Loan") after completion of
      certain criteria as stated in the Agreement, $7,000,000 in letter of
      credit commitments (the "LOC Commitment"), and $5,000,000 in working
      capital loan commitments (the "WC Loan"). Upon completion of the Project,
      the Construction Loan is due and payable or may be converted to a 15-year
      Term Loan, payable in quarterly installments through the year 2013. The
      Term Loan is available only to repay the Construction Loan. Substantially
      all of the Partnership's assets have been pledged as collateral under the
      Agreement.

      The Partnership had $94,324,049 outstanding under the Construction Loan at
      December 31, 1998. The Partnership has pledged $5,000,000 under its LOC
      Commitment for outstanding letters of credit as of December 31, 1998.

      Interest on balances outstanding under the Construction Loan and the WC
      Loan prior to conversion of Construction Loan to Term Loan, is based on
      either the base rate, as defined in the Agreement, or LIBOR plus 1.1% as
      elected by the Partnership at the time of borrowing, and was 6.66% at
      December 31, 1998. Interest on balances outstanding under the Term Loan
      and the WC Loan, subsequent to conversion of Construction Loan to Term
      Loan, is based on the rates as noted during the Construction Loan period
      and is subject to an increase in the percentage as defined in the
      Agreement. Interest on letters of credit outstanding under the LOC
      Commitment is currently 1.1%, and is subject to periodic increases during
      the term of the Agreement. The LOC Commitment also is subject to a fee of
      0.125%, due quarterly.

      The Agreement provides for commitment fees of 0.375% on the unused
      Construction Loan, WC Loan and LOC Commitment.

      To protect the Project Lender from the uncertainty of interest rate
      changes during the term of the loan, the Partnership entered into an
      agreement (the "Swap Agreement") with Chase Manhattan Bank



                                      -12-

<PAGE>

      (the "Counterparty"), a participating bank in the Loan Agreement on
      March 1, 1996. Under the Swap Agreement, the Partnership agreed to
      swap interest payments with the Counterparty. Effective December 8,
      1997, the Partnership is obligated to make fixed interest payments at
      a rate of 7.18% from effective date of December 8, 1997 through
      termination date of December 8, 2012 on a balance of $56,500,000 at
      December 8, 1997 and decreasing in accordance with the Swap Agreement.
      The Counterparty is obligated to make variable interest payments based
      on a three-month LIBOR, which was 5.2% at December 31, 1998, on the
      same balance.

      The Partnership also has a Subordinate Credit Commitment with the
      Project's Contractor. The Contractor agreed to lend the Partnership
      $15,000,000 to provide additional funding for the construction of the
      Project. The funds are available after the Construction Loan commitments
      described above have been exhausted and the Partners have made their
      equity contribution of $30,000,000 to be used for the continuation of the
      Project's construction. The term of the Subordinate Debt is nine years and
      interest on the Subordinate Debt will be calculated using the prime rate
      for the first four years and prime rate plus 1.5% for the remaining years.
      During 1998, the Partnership borrowed the full $15,000,000 available under
      the Subordinate Debt.

      During 1998, the Partnership received a notice of default from the Project
      Lender. Such default resulted in a cross-default on the Partnership's
      Subordinate Debt. See Note 2.

7.    CAPITAL CONTRIBUTIONS

      During 1997, the Construction Loan (see Note 6) was fully utilized. Each
      of the Partners made an equity contribution of $10,000,000. The last
      contributions were made December 29, 1997.

8.    NEW ACCOUNTING PRONOUNCEMENTS

      In April 1998, the American Institute of Certified Public Accountants
      issued Statement of Position 98-5 (SOP 98-5), REPORTING ON THE COSTS OF
      START-UP ACTIVITIES. This statement, which requires that costs related to
      start-up activities generally be expensed as incurred, is effective for
      fiscal years beginning after December 25, 1998. At this time, the
      Partnership has not determined the impact the adoption of this standard
      will have on the Partnership's financial statements.

      In July 1998, the Financial Accounting Standards Board issued Statement of
      Financial Accounting Standard No. 133, ("SFAS No. 133") ACCOUNTING FOR
      DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. This statement, which
      establishes accounting and reporting standards for derivative instruments,
      including certain derivative instruments imbedded in other contracts, and
      for hedging activities, is effective for fiscal years beginning after June
      15, 1999. At this time, the Partnership has not determined the impact the
      adoption of this standard will have on the Partnership's financial
      statements.

9.    SUBSEQUENT EVENTS

      On February 28, 1999, the 20 year agreement with Exelon for fuel
      management services was terminated by mutual consent among the parties.

      On March 10, 1999, the Court of Common Pleas granted the Partnership's
      motion for partial summary judgement effectively deciding the issue of
      liability on the contract claim against PECO and in favor of the
      Partnership in the matter discussed in Note 2. The trial will now be
      limited to the amount of damages PECO must pay the Partnership and the
      counts of fraud, conversion, breach of the implied covenant of good faith
      and fair dealing and breach of fiduciary duties.
      The trial is scheduled to begin March 29, 1999.

     4.   BORROWER'S REPRESENTATIONS AND WARRANTIES.  Borrower represents

                                 OPINION OF COUNSEL
                                  TO THE BORROWERS


     The opinion of counsel to the Borrowers and to NRG Morris Inc. (the 
Borrowers and NRG Morris Inc. from time to time being referred to, 
collectively, as the  "Loan Parties") and which is called for by Article 3 of 
the Supplemental Loan Agreement, as amended by the First Amendment to Loan 
Agreement dated November 30, 1998 (as amended, the "Loan Agreement") shall be 
addressed to the Lender and dated the date upon which all other conditions to 
effectiveness of the First Amendment to Loan Agreement are satisfied. It 
shall be satisfactory in form and substance to the  Lender and shall cover 
the matters set forth below, subject to such assumptions, exceptions and 
qualifications as may be acceptable to the Lender and counsel to the Lender.  
For purposes of the opinion of counsel the term "Transaction Documents" shall 
mean the Loan Agreement, the Amended and Restated Note of the Borrowers dated 
November 30, 1998 in the principal amount of $22,000,000, the Pledge 
Agreement (as such term and other capitalized terms used herein and not 
otherwise defined herein are defined in the Loan Agreement), the Security 
Documents and all agreements, instruments and documents executed and 
delivered by the Borrowers or either of them in connection with the Loan 
Agreement, the Equity Commitment Guaranty dated as of December 10, 1997 made 
by NRGG in favor of the Lender and the Assignment and Assumption Agreement 
dated as of December 10, 1997 between the Lender and Funding.

     (i)    Each Loan Party is a corporation duly incorporated and validly 
existing and in good standing under the laws of the State of Delaware and has 
and had at the time of entry into the Transaction Documents all requisite 
corporate power and authority to carry on its business as now conducted, to 
enter into the Transaction Documents executed by it and to perform all of its 
obligations under each and all of the foregoing.  Each Loan Party is duly 
qualified and in good standing as a corporation in the State of Delaware and 
as a foreign corporation in all of the jurisdictions in which the character 
of the properties owned or leased by it or the business conducted by it makes 
such qualification necessary and the failure to so qualify would permanently 
preclude the Borrower from enforcing its rights with respect to any material 
asset or expose the Borrower to material liability.  

     (ii)   The execution, delivery and performance by each Loan Party of the 
Transaction Documents have been duly authorized by all necessary corporate 
action by such Loan Party.

     (iii)  The Transaction Documents constitute the legal, valid and binding 
obligations of each Loan Party executing the same, enforceable against such 
Loan Party in accordance with their respective terms.

     (iv)   The execution, delivery and performance by each Loan Party of the 
Transaction Documents executed by it did not and will not (i) violate any 
provision of any law, statute, rule or regulation or, to the best knowledge 
of such counsel, any order, writ judgment, injunction, decree, determination 
or award of any court, governmental agency or arbitrator presently in effect 
having applicability to such Loan Party, (ii) violate or contravene any 
provision of the 

<PAGE>


Certificate of Incorporation or bylaws of such Loan Party, or (iii) result in 
a breach of or constitute a default under any indenture, loan or credit 
agreement or any other agreement lease or instrument known to such counsel to 
which such Loan Party is a party or by which it or any of its properties may 
be bound or result in the creation of any Lien thereunder.

     (v)    No order, consent, approval, license, authorization or validation 
of, or filing, recording or registration with, or exemption by, any 
governmental or public body or authority was or is required on the part of 
any Loan Party to authorize, or was or is required in connection with the 
execution, delivery either performance of, or the legality, validity, binding 
effect or enforceability of, the Transaction Documents, except for any 
necessary filing or recordation of or with respect to any of the Security 
Documents.

     (vi)   The best knowledge of such counsel, there are no actions, suits 
or proceedings pending or threatened against or affecting any Loan Party or 
any of its properties before any court or arbitrator, or any governmental 
department, board, agency or other instrumentality which (i) challenge the 
legality, validity or enforceability of the Transaction Documents, or (ii) if 
determined adversely to a Loan Party, would have a material adverse effect on 
the business, operations, property or condition (financial or otherwise) of 
such Loan Party and its Subsidiaries as a consolidated enterprise or on the 
ability of such Loan Party to perform its obligations under the Transaction 
Documents.

     (vii)  The Pledge Agreement creates the lien it purports to create upon 
the properties and interests specifically described therein. The descriptions 
of properties and interests in the Security Documents and any related 
financing statements are adequate for the purpose of such instruments and for 
perfection of the liens of the Lender. The filing of the Uniform Commercial 
Code financing statements executed by Funding and by NRG Morris Inc. and 
filed in [describe filing office] on [state dates of filings] perfected the 
Liens created under the Pledge Agreement and such Liens continue to be 
perfected on the date hereof.

<PAGE>

     7.   Upon expiration of the rescission period described in paragraph I 8 
of this Agreement, Cogen shall pay Sherman the sum of Four Hundred and Six 
Thousand Dollars ($406,000.00) which shall include payment for Sherman's

In addition, upon expiration of the rescission period described in Paragraph 
18 of this Agreement, NRG shall pay Sherman the sum of One Hundred Thirty 
Thousand Dollars ($130,000.00). These two payments together constitute the 
"Settlement Payments." The Settlement Payments shall be allocated as follows:

     PAYABLE BY COGEN:

     a.   The sum of $82,500 as payment for Sherman's outstanding shares of 
          stock.  This sum is not subject to withholding or Form 1099 tax 
          reporting.

     b.   The sum of $70,000 as payment for emotional distress, general damages,
          and settlement of any and all other claims.  This sum is not subject
          to withholding but shall be reported on Form 1099.

     c.   The sum of $253,500 (prior to withholding) as settlement of severance
          and any and all claims under the Sherman Employment Agreement or
          arising out of the employment relationship.  This sum is subject to
          withholding and will be reported on Form W-2.

          TOTAL:              $406,000

<PAGE>

     PAYABLE BY NRG:
     
     The sum of $130,000 as payment for emotional distress, general damages, and
     settlement of any and all other claims.  This sum is not subject to
     withholding but will be reported on Form 1099.
     
     Sherman shall sign all tax withholding and other forms required by Cogen 
and NRG under applicable law.  Except for items (a) and (b) above, all 
amounts paid to Sherman by Cogen under this paragraph are payments on account 
of wages and are, therefore, subject to withholding obligations under state 
and federal law, and only the net amount after applicable withholdings shall 
be paid to Sherman.  If it is determined by any federal or state tax 
authority that any amount that may be paid to Sherman under this Settlement 
Agreement but is treated by Cogen and/or NRG as not subject to information 
reporting, or treated as a payment other than taxable wages, was in fact 
subject to such reporting and/or was taxable wages, and if as a consequence 
Cogen and/or NRG is held responsible for the employee's portion of any 
penalties, interest or taxes, Sherman shall immediately upon Cogen and/or 
NRG's demand therefor and reasonable proof of Cogen and/or NRG's actual 
payment of the same, indemnify and hold Cogen and/or NRG harmless for the 
employee's portion of all such penalties, interest and taxes.

     8.   Sherman represents and warrants that he is the record and 
beneficial owner of five thousand five hundred (5,500) shares of Cogen stock, 
that such stock has not been pledged or encumbered in any way, and that he 
can sell and convey such stock free and clear of any lien of encumbrance.  
Sherman further represents and warrants that he has no record or beneficial 
ownership or interest in any other Cogen stock with the sole exception of 
stock options granted to him pursuant to the Sherman Employment Agreement, 
pursuant to which his options to purchase thirty five thousand (35,000) 
shares, and only thirty five thousand (35,000) shares, have vested.  
Contemporaneously with the payment of the sum provided for in paragraph 7 


<PAGE>

herein, Sherman shall deliver and convey legal title to, and all beneficial 
interest in, free and clear of any lien or encumbrance, all of the Cogen 
stock he owns, that is five thousand five hundred (5,500) shares, to Cogen.  
In connection with his conveyance of this Cogen stock, Sherman shall execute 
all documents reasonably requested by Cogen to effect such conveyance, 
including stock powers.

     9.   While NRG owns 20% or more of the outstanding shares of Cogen or 
its successors, but in no event for a period of time in excess of 10 years, 
Sherman shall not acquire, directly or indirectly, or otherwise become the 
beneficial owner of any common stock of Cogen (or any successor to Cogen by 
merger or otherwise) or any security or other right which is convertible, 
exchangeable or exercisable, with or without consideration into common stock 
of Cogen (or any successor to Cogen by merger or otherwise), with the sole 
exception that he may exercise some or all of his vested options to purchase 
thirty five thousand (35,000) shares of Cogen stock, provided that he 
contemporaneously sells or conveys all legal and beneficial interest in such 
stock to Cogen for fair market value.  If Cogen does not purchase such stock 
within five (5) business days, Sherman may sell such shares to one or more 
third parties, provided that such sale is completed and such stock is sold 
within twenty (20) business days of Sherman's exercise of his option or 
options.  For purposes of this Agreement, "fair market value" shall mean the 
average, for the ten trading days prior to the date on which Sherman's 
exercise his options, of the closing sale price of the shares of Cogen stock 
(or in the event no sale takes place on any day, the average of the closing 
bid and asked quotations for the shares of Cogen stock on such day) on the 
National Association of Securities Dealers Automatic Quotation System 
("NASDAQ") or any comparable system.

<PAGE>

     The parties expressly acknowledge and agree that Sherman shall maintain 
the right to exercise his vested options to purchase up to thirty five 
thousand (35,000) shares of Cogen stock for ninety (90) calendar days after 
December 31, 1998.  The parties also expressly acknowledge and agree that 
Sherman's vested stock options total thirty five thousand (35,000) and that 
he will not acquire any further options to purchase Cogen stock pursuant to 
any agreement with Cogen, any Cogen stock option plan, or otherwise except as 
provided in this paragraph 9.

     10.  Sherman agrees to serve as an independent contractor consultant for 
Cogen during the period from January 1, 1999 through December 31, 2001.  In 
this capacity, Sherman will consult with Cogen, or its representatives, for 
up to ten (10) days per calendar year.  In consideration for Sherman serving

($20,000) upon expiration of the rescission period described in paragraph 18 
of this Agreement; Twenty Thousand Dollars ($20,000) on the date which is one 
year after the first Twenty Thousand Dollar ($20,000) payment; and Twenty 
Thousand Dollars ($20,000) on the date which is two years after the first 
Twenty Thousand Dollar ($20,000) payment.  If Cogen requires additional 
consulting services from Sherman during this period, Sherman shall provide 
such services as are mutually agreeable in consideration for payments in the 
amount of Two Thousand Five Hundred Dollars ($2,500) per day.  Sherman shall 
be reimbursed by Cogen for reasonable expenses which he incurs in performing 
consulting services under this paragraph.  Cogen shall report such payment to 
applicable state and federal tax agencies.  Sherman understands that he is 
not an employee of Cogen for purposes of providing services under this 
paragraph, and that, as such, he is not eligible to have benefits in any 
employee health or welfare benefit plan, or any other benefits from Cogen.

     11.  Cogen and Sherman will issue a joint statement, in the form 
attached hereto as Exhibit A, promptly after expiration of the rescission 
period described in paragraph 18 and completion of the filings required by

     12.  Sherman shall have the right, at his sole option, to purchase or 
transfer the lease of the Chevrolet Tahoe vehicle presently being used by 
Sherman pursuant to Cogen's lease of the vehicle.  If Sherman elects to 
purchase or transfer the lease of the vehicle, he shall advise Cogen in 
writing of his decision to do so by January 25,1999.  If Sherman has not 
advised Cogen in writing of his decision to purchase or transfer the lease of 
the vehicle by January 25, 1999, his right to do so shall expire, he shall 
have no further right to possess or use the vehicle, and he shall return the 
vehicle and keys to the vehicle to Cogen on or before January 25, 1999.

     13.  NRG shall contribute a total of Thirty Thousand Dollars ($30,000) 
to a bona fide Section 501(c)(3) qualified organization for environmental

Dollars ($10,000) beginning December 31, 1999.  Sherman shall have the right 
to determine whether such sum shall be paid as a lump sum or in annual 
increments.  This 501(c)(3) qualified organization shall be established by 
Sherman and if not, the contribution shall be made to a bona fide 501(c)(3) 
qualified organization or charitable organization as determined by the mutual 
agreement of the parties.

     14.  Cogen and NRG agree that their respective directors and officers 
will not make any statement to any third party disparaging Sherman and 
Sherman agrees that he will not make any statement to any third party 
disparaging Cogen or NRG, or any of their respective present or former 
directors or officers.

     15.  Cogen, NRG, and Sherman agree to maintain the terms of this

     20.  The parties agree that this Agreement will not be assignable by

                             [COGEN AMERICA LETTERHEAD]


     CogenAmerica and Robert T. Sherman, Jr., its Chief Executive Officer, 
announced today that they have agree upon terms under which Mr. Sherman will 
step down as President and CEO and provide consulting services to the 
Company. The Company and NRG Energy, Inc., owner of 45.4% of the Company's 
stock, had previously announced that Mr. Sherman's employment had been 
terminated for expenditures incurred in connection with the solicitation of 
proxies on behalf of the Company without authorization from the Company's 
Board of Directors. After an investigation by the Company's Board of 
Directors, it was determined that these expenditures were approved by the 
Independent Directors Committee and were within Mr. Sherman's authority as 
established by the Board of Directors. Further, the Company acknowledged that 
any media accounts accusing Mr. Sherman of mismanagement were inaccurate.

     Julie Jorgensen, interim President and CEO of the Company, said "Bob 
Sherman and CogenAmerica have reached an amicable resolution of all issues 
between them.  Mr. Sherman acted within the authority bestowed on him by the 
Company's Board of Directors.  Bob has agreed to remain a consultant to the 
Company in the transition to a new CEO, and we are glad to have his help."

     David Peterson, Chairman, CEO and President of NRG Energy also stated 
that: "We are pleased that our investigation has shown that Bob Sherman's 
actions were authorized, and that his matter has been resolved to the 
satisfaction of all concerned."

     In a joint statement, Mr. Sherman said "I am proud of my accomplishments at
CogenAmerica, and will continue to assist the Company in achieving a smooth
transition to new 

<PAGE>

leadership.  I am especially pleased that CogenAmerica, NRG Energy and I 
could rise above our differences and resolve our differences quickly and 
amicably."

RELEASE CONTAINS FORWARD-LOOKING STATEMENTS WITHIN THE MEANING OF SECTION 27A

                      REPRESENTATIONS AND WARRANTIES
     
     In order to induce the Lender to enter into this Agreement and to make the
Loan available, each Cogen Entity hereby represents and warrants to the Lender
(which representations and warranties shall survive the execution and delivery
of this Agreement and the Note and the drawdown of the Loan hereunder) that, as
of the Funding Date:
     
     (a)  DUE ORGANIZATION AND POWER.  Each Cogen Entity is duly organized,
validly existing and in good standing under the laws of its jurisdiction of
organization and is properly qualified to do business and in good standing in
every jurisdiction where the failure to maintain such qualification or good
standing could reasonably be expected to result in a Material Adverse Effect. 
Each Cogen Entity has full power to carry on its business as now being conducted
and has complied with all statutory, regulatory and other requirements relative
to such business and such agreements, except where non-compliance could not
reasonably be expected to result in a Material Adverse Effect.  Each Cogen
Entity has full power and authority to enter into and perform its obligations
under the Credit Documents to which it is a party.
     
     (b)  CAPITALIZATION.  The authorized capital stock or other equity
interests of OLAC and OLAC Holding are held as set forth on Schedule 5(b) and
except as set forth thereon, no other shares of the capital stock or other
equity interests of either OLAC or OLAC Holding are issued and outstanding.  All
of the issued and outstanding shares of capital stock of OLAC and OLAC Holding
are duly authorized and validly issued, fully paid, nonassessable, and free and
clear of all Liens (other than Permitted Liens), and such shares were issued in
compliance with all applicable state, federal and foreign laws concerning the
issuance of securities.  There are no preemptive or other outstanding rights,
options, warrants, conversion rights or similar agreements or understandings for
the purchase or acquisition of shares of capital stock or other securities or
equity interests of OLAC or OLAC Holding.  CogenAmerica is the sole owner of

                                   13
<PAGE>

100% of the outstanding equity interests of OLAC Holding, and OLAC Holding is
the owner of 100% of the outstanding equity interests of OLAC, each free and
clear of all Liens.
     
     (c)  AUTHORIZATION AND CONSENTS.  All necessary corporate action has been
taken to authorize, and all necessary consents and authorities have been
obtained and remain in full force and effect to permit, each Cogen Entity to
enter into and perform its respective obligations under the Credit Documents to
which it is a party and to borrow and repay the Loan.  No further consents or
authorities are necessary for the repayment of the Loan or any part thereof,
including, without limitation, any consent or approval of, or notice to, or
other action with or by, any Governmental Authority, regulatory body or any
other Person which has not been made or obtained and is in full force and
effect.
     
     (d)  BINDING OBLIGATIONS.  Each Credit Document constitutes or when
executed and delivered, will constitute the legal, valid and binding obligations
of each Cogen Entity to the extent it is a party, enforceable against such
parties in accordance with their respective terms, except to the extent that
such enforcement may be limited by equitable principles, principles of public
policy or applicable bankruptcy, insolvency, reorganization, moratorium or other
laws affecting generally the enforcement of creditors' rights.
     
     (e)  NO VIOLATION.  The execution and delivery of, and the performance of
the provisions of, each Credit Document to which it is or will be a party by
each Cogen Entity do not contravene any applicable law or regulation existing at
the date hereof, any Governmental Approval or any contractual restriction
binding on such party or the certificate of incorporation or by-laws (or
equivalent instruments) thereof.
     
     (f)  LITIGATION.  Except as set forth on Schedule 5(f), no action, suit or
proceeding is pending or, to any Cogen Entity's knowledge, threatened against
any Cogen Entity before any court, board of arbitration or administrative agency
which could reasonably be expected to result in any Material Adverse Effect. 
There is no injunction, writ, preliminary restraining order or any order of any
nature issued by an arbitrator or other Governmental Authority directing that
any material aspect of the transactions provided for in this Agreement not be
consummated as herein or therein provided.
     
     (g)  NO DEFAULT.  None of the Cogen Entities is in default under any
material agreement by which it is bound, or is in default in respect of any
financial commitment or obligation, in either case the default of which could
reasonably be expected to result in a Material Adverse Effect.
     
     (h)  PROJECT AGREEMENTS.  Upon the Funding Date:
          
          (i)    Each Material Governmental Approval required in connection
                 with the MCPC Facility has been obtained, is validly issued,
                 is in full force and effect, is not subject to appeal by any
                 Person, and, to the knowledge of the Cogen Entities, is free
                 from conditions or requirements compliance with which could
                 reasonably be expected to result in a Material Adverse Effect. 

                                   14
<PAGE>


                 There is no proceeding pending or, to the knowledge of Cogen
                 Entities, threatened which is reasonably likely to result in
                 the rescission, revocation, material modification, suspension,
                 determination of invalidity or limitation of effectiveness of
                 any Material Governmental Approval.  To the knowledge of the
                 Cogen Entities, the information set forth in each application
                 and other written material submitted by or on behalf of any of
                 the Cogen Entities to the applicable Governmental Authority in
                 connection with such Material Governmental Approval was
                 accurate and complete in all material respects at the time
                 such application or other written material was submitted. 
                 Each of the Cogen Entities complies in all material respects
                 with all covenants, conditions, restrictions and reservations
                 in the Material Governmental Approvals relating to the MCPC
                 Facility and the Project Agreements applicable thereto and all
                 laws applicable thereto, except to the extent any
                 noncompliance could not reasonably be expected to result in a
                 Material Adverse Effect;
          
          (ii)   Each Project Agreement is a legal, valid and binding agreement
                 enforceable in accordance with its terms, except to the extent
                 enforceability may be limited by applicable bankruptcy,
                 insolvency, moratorium, reorganization or other similar laws
                 affecting the enforcement of creditors' rights and subject to
                 general equitable principles;
          
          (iii)  All representations and warranties set forth in each Project
                 Agreement by OLAC or its predecessors which is a party thereto
                 are true and correct in all material respects (the
                 determination of such material truth and correctness to be
                 made by the Lender in good faith) as though made as of the
                 date hereof, except to the extent any such representation or
                 warranty relates to a prior date; and
          
          (iv)   The facilities of OLAC will be able to be operated on a safe
                 and commercially sound basis in compliance with all
                 Governmental Approvals and applicable Project Agreements and
                 laws, so that the performance and facility guarantees and
                 specifications provided for in the applicable Project
                 Agreements and Governmental Approvals can be substantially met
                 during the term of this Agreement and OLAC can duly and
                 punctually meet its obligations under the applicable Project
                 Agreements and Governmental Approvals in accordance with the
                 terms thereof, except to the extent any inadvertent
                 noncompliance with such Governmental Approvals and Project
                 Agreements could not reasonably be expected to have a Material
                 Adverse Effect; provided, however, that such inadvertent
                 noncompliance must be remedied or cured within 30 days of OLAC
                 obtaining knowledge thereof.  OLAC has adequate inventories
                 and spare parts to operate the MCPC Facility in accordance
                 with the Project Agreements, Governmental Approvals and
                 applicable law.

     (i)  INSURANCE.  Schedule 5(i) (which shall be updated by the Cogen
Entities and provided to the Lender not less often than annually) sets forth a
complete and accurate description of all material policies of insurance that
will be in effect as of the Funding Date with respect to the MCPC Facility.  To
the knowledge of the Cogen Entities, such policies are with companies rated "A-"
or better by Best's Insurance Guide and Key Rating or other insurance companies
of recognized responsibility satisfactory to the Lender and the coverages
provided by such policies are in amounts and cover such risks as are usually
carried by companies engaged in similar businesses and owning similar properties
in the same general areas in which OLAC operates.
     
     (j)  FINANCIAL INFORMATION.  Except as otherwise disclosed in writing to
the Lender on or prior to the date hereof, all financial statements, information
and other data furnished by any of the Cogen Entities to the Lender are complete
and correct, such financial statements have been prepared in accordance with
GAAP (except, in the case of interim financial statements, for the absence of
footnotes) and accurately and fairly present the financial condition of the
parties covered thereby as of the respective dates thereof and the results of
the operations thereof for the period or respective periods covered by such
financial statements and since such date or dates, there has been no Material
Adverse Effect as to any of such parties and none thereof has any contingent
obligations, liabilities for taxes or other outstanding financial obligations
which are material in the aggregate except as disclosed in such statements,
information and data.
     
     (k)  TAX RETURNS.  Each Cogen Entity has filed all material tax returns
required to be filed thereby and has paid all taxes payable thereby which have
become due, other than those not yet delinquent or the nonpayment of which would
not have a Material Adverse Effect on such Party and except for those taxes the
amount or validity of which is currently being contested in a Good Faith
Contest.
     
     (l)  ERISA.  The execution and delivery of the Credit Documents and the
consummation of the transactions hereunder will not involve any prohibited
transaction within the meaning of ERISA or Section 4975 of the Code and no
condition exists or event or transaction has occurred in connection with any
Plan maintained or contributed to by any Cogen Entity or any ERISA Affiliate
resulting from the failure of any thereof to comply with ERISA insofar as ERISA
applies hereto which is reasonably likely to result in such party or any ERISA
Affiliate incurring any liability, fine or penalty which individually or in the
aggregate would have a Material Adverse Effect.  Prior to the Funding Date, the
Cogen Entities have delivered to the Lender a list of all Plans to which any
Cogen Entity or any ERISA Affiliate is a "party in interest" (within the meaning
of Section 2(14) of ERISA) or a "disqualified person" (within the meaning of
Section 4975(e)(2) of the Code).
     
     (m)  MARGIN REGULATIONS.  None of the Cogen Entities is engaged in the
business of extending credit for the purpose of purchasing or carrying margin
stock (within the meaning of Regulation G, T, U, or X of the Board of Governors
of the Federal Reserve System) and no proceeds of any Loan will be used in a
manner which would violate or result in a violation of, such Regulation, G, T,
U, or X.

                                   16

     (n)  INVESTMENT COMPANY ACT.  None of the Cogen Entities is an "investment
company" nor a company "controlled" by an "investment company" within the
meaning of the Investment Company Act of 1940, as amended.
     
     (o)  SECURITY INTERESTS.  Except for the consents set forth on Schedule
5(o), no consents are required to create a first priority perfected Lien in any
of the Collateral under and as described in the Security Documents, and the
Liens created in favor of the Lender under the Security Documents are valid and
perfected, first priority Liens (subject only to Permitted Liens) superior and
prior to the rights of all Persons (except those rights of the holders of
Permitted Liens), whether the property subject to the security interests is now
owned by the party granting such security interest or is hereafter acquired. 
The Security Documents (including Uniform Commercial Code financing statements)
have been filed, recorded and/or registered in each office and in each
jurisdiction where required to create and perfect the lien and security interest
described above.  The chief executive office and chief place of business of each
of Cogen Entity and the office in which the records relating to the earnings and
other receivables of each such party are kept is located, as of the date hereof,
at the locations set forth on Schedule 5(o) for such party.  Such locations are
the sole offices or places of business maintained by each such party as of the
date hereof.  To the knowledge of the Cogen Entities, no such party has
transacted any business during the five year period prior to the date of this
Agreement under any name other than those set forth on Schedule 5(o).
     
     (p)  BUSINESS OF PROJECT ENTITIES.  Neither OLAC Holding nor OLAC has
engaged in any business other than the operation of the MCPC Facility nor is any
such party a party to any contract, operating lease, agreement or commitment
which, either individually, or in the aggregate is material to the operation of
the MCPC Facility other than the Project Agreements applicable thereto.
     
     (q)  QUALIFYING COGENERATION MCPC FACILITY STATUS.  All necessary filings
have been made to establish and maintain "qualifying facility" status under
PURPA for the MCPC Facility, provided that the Cogen Entities will promptly file
a recertification certificate with the Federal Energy Regulatory Commission. 
The MCPC Facility is owned and will be operated in the manner contemplated by
the certificate conferring upon it "qualifying facility" status.
     
     (r)  TITLE TO AND SUFFICIENCY OF ASSETS.  Except as set forth on Schedule
5(r), CogenAmerica had good, valid and sufficient title to the Pledged Stock of
OLAC Holding and each of OLAC Holding and OLAC has good, valid and sufficient
title to its assets and properties and as to each of such Cogen Entities, such
Pledged Stock, assets and properties are free and clear of all liens other than
Permitted Liens of OLAC Holding and OLAC.  Each Cogen Entity has good,
marketable, indefeasible and insurable title in fee simple (or its equivalent
under applicable law) to the real property owned by it.  None of the real
property owned or leased by any Cogen Entity is located within any federal,
state or municipal flood plain.  All leases necessary for the conduct of the
business of each Cogen Entity as presently conducted and as proposed to be
conducted are valid and subsisting and are in full force and effect.  Each Cogen
Entity enjoys peaceful and undisturbed possession under all material leases to
which they are parties.  The services to be performed, the materials to be
supplied and the easements, licenses

such party to obtain all services, materials or rights (including access) 
required for the operation and maintenance of the MCPC Facility, including 
such party's full and prompt performance of its obligations, and full and 
timely satisfaction of all conditions precedent to the performance by others 
of their obligations under such Project Agreements and Governmental Approvals.

or grievances, charges or complaints with respect to any employee or group of
employees pending or, to the knowledge of any Cogen Entity, threatened against
any Cogen Entity.
     
     (t)  TRANSACTIONS WITH AFFILIATES.  Set forth on Schedule 5(t) is a true,
accurate and complete description of all transactions between or among OLAC and
OLAC Holding and between or among each of them and any Affiliate of any such
party (other than the Lender) which required or which will require in the case
of OLAC or OLAC Holding the payment by such party of an aggregate amount equal
to or greater than $100,000 during any twelve-month period.

                 Environmental Approval, and in each case which could
                 reasonably be expected to have Material Adverse Effect

     (f)  A court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that:
     
          (i)    is for relief against any Cogen Entity or any Subsidiary of
                 any Cogen Entity in an involuntary case;
     
          (ii)   appoints a custodian of any Cogen Entity or any Subsidiary of
                 any Cogen Entity or for any substantial part of its property;

     (i)  Any "Event of Default" shall occur under the Existing NRG Loan
Agreement; or
     
     (j)  OLAC shall revoke, breach or anticipatorily repudiate the Guaranty or
any term or provision therein or assert or threaten any defense, right of set
off or counterclaim against the enforcement thereof., the Guaranty or any term
or provision therein.
     
     The foregoing will constitute Events of Default whatever the reason for any
such Event of Default and whether it is voluntary or involuntary or is effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any Administrative or governmental body.
     
     A Default under clause (c) is not an Event of Default until the Lender
notifies any Cogen Entity of the Default and the Cogen Entities do not cure such
Default within the time specified after receipt of such notice.  Such notice
must specify the Default, demand that it be remedied and state that such notice
is a "Notice of Default".
     
     SECTION 7.02.  ACCELERATION.  If an Event of Default (other than an Event
of Default specified in Section 7.01(e) or (f) with respect to any Cogen Entity
occurs and is continuing, the Lender by notice to any Cogen Entity may declare
the principal of and accrued interest on the Loan (together with all other
Obligations) to be due and payable.  Upon such a declaration, such Obligations
shall be due and payable immediately.  If an Event of Default specified in
Section 7.01 (e) or (f) with respect to any Cogen Entity occurs, the Obligations
shall IPSO FACTO become and be immediately due and payable without any
declaration or other act on the part of the Lender.  The Lender by notice to any
Cogen Entity may rescind an acceleration and its consequences.  No such
rescission shall affect any subsequent Default or impair any right consequent
thereto.
     
     SECTION 7.03.  DEFAULT AND REMEDIES.
     
     If, following the Funding Date, and so long as there shall remain
outstanding any Obligations hereunder, an Event of Default occurs and is
continuing, the Lender shall have all of the remedies of a secured party under
the Uniform Commercial Code, including, without limitation, the right to notify
OLAC and/or OLAC Holding to pay directly to the Lender any amount payable to any
Cogen Entity in respect of the Pledged Stock.  In addition to and not in
derogation of any or all of the rights and remedies granted hereunder to the
Lender or otherwise available to the Lender under applicable law, following the
Funding Date and such an Event of Default, so long as there shall remain any
outstanding Indebtedness hereunder, the Lender shall have the further right and
power, at its sole option, to sell, or otherwise dispose of, the Collateral
(other than Collateral consisting of cash), or any part thereof, at any one or
more public or private sales as permitted by applicable law, and for that
purpose the Lender may take immediate and exclusive possession of such
Collateral, or any part thereof, to the extent capable of possession.
     
     To the fullest extent permitted by law, each Cogen Entity irrevocably and
expressly waives any right to receive any notice of sale or notice of any other
disposition of all or any part of the Collateral that does not consist of cash,
except that to the extent may be entitled by 

                                 29
<PAGE>

applicable law to any notice of sale or other disposition of such Collateral, 
each Cogen Entity agrees that if such notice is mailed, postage prepaid, to 
any Cogen Entity at such party's address hereinafter specified not less than 
five (5) days before the time of the sale or other disposition contemplated 
therein, such notice shall conclusively be deemed commercially reasonable and 
shall fully satisfy any requirement for giving of said notice.  The Lender 
shall not be obligated to make any sale of Collateral regardless of notice of 
sale having been given.  The Lender may adjourn any public or private sale 
from time to time by announcement at the time and place fixed therefor, and 
such sale may, without further notice, be made at the time and place which it 
was so adjourned.
     
     The proceeds realized upon any such disposition, after deduction for the
expenses of retaking, holding, preparing for sale, selling or the like and
reasonable attorneys' fees, legal expenses and costs incurred by the Lender,
shall be applied in accordance with Section 7.06.
     
     The remedies of the Lender hereunder or under any Credit Documents are
Cumulative and the exercise of any one or more of the remedies provided herein,
or under the Uniform Commercial Code or other applicable law, shall not be
construed as a waiver of any other rights or remedies of the Lender so long as
any part of the Obligations remain unsatisfied or unperformed.  The making of
this Agreement shall not waive or impair any other security the Lender may have
or hereafter acquire for the payment or performance of the Obligations, nor
shall the making of any such additional security waive or impair this Agreement;
but the Lender may resort to any security it may have in the order it may be
deemed proper.
     
     SECTION 7.04.  OTHER REMEDIES.  If, following the Funding Date, and so long
as there shall remain outstanding Obligations, an Event of Default occurs and is
continuing, the Lender may pursue any available remedy to collect the payment of
all outstanding Obligations or to enforce the performance of any provision of
the Note, this Agreement, or any other Credit Document.  The Lender may maintain
a proceeding even if it does not possess the Note or does not produce it in the
proceeding.  A delay or omission by the Lender in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.  No remedy is
exclusive of any other remedy.  All available remedies are cumulative.
     
     SECTION 7.05.  WAIVER OF PAST DEFAULTS.  The Lender by notice to any Cogen
Entity may waive an existing Default and its consequences (subject to any
limitations expressly set forth in such waiver).  When a Default is waived, it
is deemed cured, but no such waiver shall extend to any subsequent or other
Default or impair any consequent right.
     
     SECTION 7.06.  PRIORITIES.  If the Lender collects any money or property
pursuant to this Article 7, it shall pay out the money or property in the
following order:
     
     FIRST: to itself in accordance with the priority set forth in Section 2.09
     until all Obligations have been indefeasibly satisfied in full; and
     
     SECOND: to the extent of any excess, to the Borrowers.

                                 30
<PAGE>

     
     SECTION 7.07.  UNDERTAKING FOR COSTS.  In any suit for the enforcement of
any right or remedy under this Agreement a court in its discretion may require
the filing by any party litigant in the suit of an undertaking to pay the costs
of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in the suit,
having due regard to the merits and good faith of the claims or defenses made by
the party litigant.
     
     SECTION 7.08.  WAIVER OF STAY OR EXTENSION Laws.  Each Cogen Entity (to the
extent permitted by applicable law) shall not at any time insist upon, or plead,
or in any manner whatsoever claim or take the benefit or advantage of, any stay
or extension law wherever enacted, now or at any time hereafter in force, which
may affect the covenants or the performance of this Agreement; and each Cogen
Entity (to the extent that it may lawfully do so) hereby expressly waives all
benefit or advantage of any such law, and shall not hinder, delay or impede the
execution of any power herein granted to the Lender, but shall suffer and permit
the execution of every such power as though no such law had been enacted.

                               SUBORDINATION; WAIVERS
     
     SECTION 8.01.  SUBORDINATION.  The Indebtedness evidenced by the Note is
subordinate in certain respects to the Indebtedness (the "MeesPierson
Obligations") under and as that term is defined in that certain Credit Agreement
dated December 17, 1997 (the "MeesPierson Credit Agreement") entered into by and
among CogenAmerica, MeesPierson Capital Corporation and the other Lenders party
thereto (collectively the "MeesPierson Lenders"), to the extent and in the
manner provided in that certain Subordination Agreement by and between those
parties and the Lender dated as of October 9, 1998.  Each Cogen Entity shall
cause all other Indebtedness incurred by it to be subordinated on terms and
conditions satisfactory to the Lender, to the prior payment in full of the Note
and that each such subordination is for the benefit of and enforceable by the
holders of the Note.  Each Cogen Entity acknowledges and agrees that the terms
of any subordination agreement contemplated in this paragraph define the
relative rights of its creditors between such creditors and in no way affect the
obligations of any Cogen Entity to the Lender.
     
     SECTION 8.02.  WAIVER OF CONTRIBUTION, SUBROGATION, OTHER RIGHTS.  Each
Cogen Entity hereby agrees that, from the date of this Agreement until the
Obligations and the MeesPierson Obligations have each been indefeasibly paid in
full, or this Agreement has been earlier terminated, it will not exercise any
rights which it may have or acquire, at law or in equity, by way of
contribution, subrogation, indemnity or similar principles as a result of
payments made by any Cogen Entity to the Lender hereunder.  Each Cogen Entity
expressly acknowledges that it will benefit directly from the Loan hereunder and
that each of the Obligations are intended to be direct obligations and not a
guarantee or in the nature of a guarantee.  If, notwithstanding the express
intention of the parties to the contrary, all or any portion of the Obligations
of any Cogen Entity are deemed a guarantee or in the nature of a guarantee, then
each Cogen Entity hereby agrees that, from the date of this Agreement until the
Obligations and the MeesPierson 

                                 31
<PAGE>

Obligations have each been indefeasibly paid in full, or this Agreement has 
been earlier terminated, it will not exercise any suretyship, accommodation 
party, guarantor and similar defenses and rights arising under any of the 
Credit Documents as a result of the Loan hereunder, and any such party shall 
be and remain liable for any deficiency remaining after foreclosure of any 
Lien under any of the Security Documents, whether or not the liability of the 
primary party obligated thereunder or any other obligor for such deficiency 
is discharged Pursuant to statute or judicial decision, nor shall the Lender 
be required to martial assets or remedies or first to resort for payment of 
the Obligations to the primary obligor therefor or other parties or first to 
enforce, realize upon or exhaust any Collateral for the Obligations, before 
seeking collection of the Obligations from or enforcing any other rights or 
remedies against such deemed surety, guarantor or accommodation party.  This 
Section 8.02 shall inure to the benefit of the Lender and to the benefit of 
the MeesPiersn Lenders.

           such action or proceeding was brought in an inconvenient court and
           agrees not to plead or claim the same;
     
     (iii) agrees that service of process in any such action or proceeding may
           be effected by mailing a copy thereof by registered or certified mail
           (or any substantially similar form of mail), postage prepaid, to such
           party at its address set forth in Section 9.02; and

     (iv)  agrees that nothing herein shall affect the right to effect service
           of process in any other manner permitted by law or shall limit the
           right to sue in any other jurisdiction.
     
     (b)  EACH PARTY HERETO UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL
ACTION OR PROCEEDING REFERRED TO IN PARAGRAPH (A) ABOVE AND ANY COUNTERCLAIM
THEREIN.
     
     SECTION 9.09.  INTEREST.  Each provision in this Agreement and each other
Credit Document is expressly limited so that in no event whatsoever shall the
amount paid, or otherwise agreed to be paid, by the Borrowers for the use,
forbearance or detention of the money to be loaned under this Agreement or any
other Credit Document or otherwise (including any sums paid as required by any
covenant or obligation contained herein or in any other Credit Document which is
for the use, forbearance or detention of such money), exceed that amount of
money which would cause the effective rate of interest to exceed the highest
lawful rate permitted by applicable law (the "Highest Lawful Rate"), and all
amounts owed under this Agreement and each other Credit Document shall be held
to be subject to reduction to the effect that such amounts so paid or agreed to
be paid which are for the use, forbearance or detention of money under this
Agreement or such Credit Document shall in no event exceed that amount of money
which would cause the effective rate of interest to exceed the Highest Lawful
Rate.  Notwithstanding any provision in this Agreement or any other Credit
Document to the contrary, if the maturity of the Loan or the obligations in
respect of the other Credit Documents are accelerated for any reason, or in the
event of any prepayment of all or any portion of the Loan or the obligations in
respect of the other Credit Documents by the Borrowers or in any other event,
earned interest on the Loan and such other obligations of the Borrowers may
never exceed the Highest Lawful Rate, and any unearned interests otherwise
payable on the Loan or the obligations in respect of the other Credit Documents
that is in excess of the Highest Lawful Rate shall be canceled automatically as
of the date of such acceleration or prepayment or other such event and (if
theretofore paid) shall, at the option of the holder of the Loan or such other
obligations, be either refunded to the Borrowers or credited on the Principal of
the Loan.  In determining whether or not the interest paid or payable, under any
specific contingency, exceeds the Highest Lawful Rate, the Borrowers and the
Lender shall, to the maximum extent permitted by applicable law, amortize,
prorate, allocate and spread, in equal parts during the period of the actual
term of this Agreement, all interest at any time contracted for, charged,
received or reserved in connection with this Agreement.
     
     SECTION 9.10.  JOINT AND SEVERAL LIABILITY.  Notwithstanding any term or
provision contained in this Agreement or any other Credit Document to the
contrary, each and every covenant, agreement and other obligation each Cogen
Entity under pursuant to any of the Credit Documents to the extent it is a party
thereto, shall constitute a joint and several duty, liability and obligation of
each Cogen Entity, as applicable.

                               1998 STOCK OPTION PLAN

                          GRANT OF INCENTIVE STOCK OPTION

DATE OF GRANT: ______________________

     THIS GRANT, dated as of the date of grant first stated above (the "Date of
Grant"), is delivered by NRG Generating (U.S.) Inc. (the "Company") to
_____________________ ("Grantee"), who is an Employee of the Company or a
Subsidiary.

     WHEREAS, the Board of Directors of the Company (the "Board") on April 20,
1998 adopted the NRG Generating (U.S.) Inc. 1998 Stock Option Plan (the "Plan")
to be effective as of that date, and the shareholders of the Company approved
the Plan on May 21, 1998.

     WHEREAS, the Plan provides for the granting of Incentive Stock Options by
the Committee to directors, officers and key employees of the Company (excluding
officers and directors who are not employees) to purchase shares of the Common
Stock of the Company (the "Stock"), in accordance with the terms and provisions
thereof; and

     WHEREAS, the Committee considers Grantee to be a person who is eligible for
a grant of Incentive Stock Options under the Plan, and has determined that it
would be in the best interest of the Company to grant the Incentive Stock
Options documented herein.

     NOW THEREFORE, the parties hereto, intending to be legally bound hereby,
agree as follows:

1.  GRANT OF OPTION.

    Subject to the terms and conditions hereinafter set forth, the Company, with
the approval and at the direction of the Committee, hereby grants to Grantee, as
of the Date of Grant, an option to purchase up to __________ shares of Stock at
a price of $___________ per share, its Fair Market Value as of the Date of
Grant. The shares of stock purchasable upon exercise of the Option are
hereinafter sometimes referred to as the "Option Shares."  The Option is
intended by the parties hereto to be, and shall be treated as, an Incentive
Stock Option under Code Section 422.

2.  INSTALLMENT EXERCISE.

    Subject to such further limitations as are provided herein, the Option shall
become exercisable in three (3) installments, Grantee having the right hereunder
to purchase from the Company the following number of Option Shares upon exercise
of the Option, on and after the following dates, in cumulative fashion:

    (i) on and after the first anniversary of the Date of Grant up to 
one-third (ignoring fractional shares) of the total number of Option Shares;

   (ii) on and after the second anniversary of the Date of Grant, up to an
additional one-third (ignoring fractional shares) of the total number of Option
Shares; and

  (iii) on and after the third anniversary of the Date of Grant, the remaining
Option Shares.


Exhibit 10.35.2
<PAGE>

3.  TERMINATION OF OPTION.

    (a)  The Option and all rights hereunder with respect thereto, to the extent
such rights shall not have been exercised, shall terminate and become null and
void after the expiration of ten (10) years from the Date of Grant (the "Option
Term").

    (b)  Upon the occurrence of Grantee's ceasing for any reason to be 
employed by the Company, the Option, to the extent not previously exercised, 
shall terminate and become null and void immediately upon the Separation 
Date, except in a case where the termination of Grantee's employment is by 
reason of retirement, Disability or death or otherwise as follows.  Upon a 
termination of Grantee's employment by reason of Disability or death, all 
unexercised portions of the Option shall become immediately exercisable and 
the Option may be exercised during the period beginning upon such termination 
and ending one year after such date. [In the event of any other termination,
the Option may be exercised within the three-month period following the date 
of retirement, but only to the extent that the Option was outstanding and 
exercisable upon the date of such retirement. In no event, however, shall any 
such period extend beyond the Option Term.]

    (c)  In the event of Grantee's death, the Option may be exercised by 
Grantee's legal representative(s) as and to the extent that the Option would 
otherwise have been exercisable by Grantee, subject to the provisions of 
Section 3(b) hereof.

    (d)  A transfer of Grantee's employment between the Company and its 
Parents or Subsidiaries shall not be deemed to be a termination of Grantee's 
employment.

    (e)  Notwithstanding any other provisions set forth herein or in the 
Plan, if Grantee shall: (i) commit any act of malfeasance or wrongdoing 
affecting the Company, its Parents or Subsidiaries, (ii) breach any covenant 
not to compete, or employment contract, with the Company, its Parents or 
Subsidiaries, or (iii) engage in conduct that would warrant Grantee's 
discharge for cause (excluding general dissatisfaction with the performance 
of Grantee's duties, but including any act of disloyalty or any conduct 
clearly tending to bring discredit upon the Company, its Parents or 
Subsidiaries), any unexercised portion of the Option shall immediately 
terminate and be void.

4.  EXERCISE OF OPTIONS.

    (a)  Grantee may exercise the Option with respect to all or any part of 
the number of Option Shares that are exercisable hereunder by giving the 
Secretary of the Company written notice of intent to exercise.  The notice of 
exercise shall specify the number of Option Shares as to which the Option is 
to be exercised and date of exercise thereof, which date shall be at least 
five (5) days after the signing of such notice unless an earlier time shall 
have been mutually agreed upon.

    (b)  Full payment (in U.S. dollars) by Grantee of the Option Price for 
Option Shares purchased shall be made on or before the exercise date 
specified in the notice of exercise in cash, or as the Company may otherwise 
permit as further set forth in the Plan.  On the exercise date specified in 
Grantee's notice or as soon thereafter as is practicable, the Company shall 
cause to be delivered to Grantee, a certificate or certificates for the 
Option Shares then being purchased (out of theretofore unissued Stock or 
reacquired Stock, as the Company may elect) upon full payment for such Option 
Shares.  The obligation of the Company to deliver Stock shall, however, be 
subject to the condition that if at any time the Committee shall determine in 
its discretion that the listing, registration or qualification of the Option 
or the Option Shares upon any securities exchange or under any state or 
federal law, or the consent or approval of any governmental regulatory body, 
is necessary or desirable as a condition of, or in connection with, the 
Option or the issuance or purchase of Stock thereunder, the Option may not be 
exercised in whole or in part unless such listing, registration, 
qualification, consent or approval shall have been effected or obtained free 
of any conditions not acceptable to the Committee. 


Exhibit 10.35.2                       2

<PAGE>

    (c)  If Grantee fails to pay for any of the Option Shares specified in 
such notice or fails to accept delivery thereof, Grantee's right to purchase 
such Option Shares may be terminated by the Company or the exercise of the 
Option may be ignored, as the Committee in its sole discretion may determine. 
The date specified in Grantee's notice as the date of exercise shall be 
deemed the date of exercise of the Option, provided that payment in full for 
the Option Shares to be purchased upon such exercise shall have been received 
by such date.

5.  ADJUSTMENT OF AND CHANGES IN STOCK.

    In the event of a reorganization, recapitalization, change of shares, 
stock split, spin-off, stock dividend, reclassification, subdivision, or 
combination of shares, merger, consolidation, rights offering, or any other 
change in the corporate structure of shares of capital stock of the Company, 
the Committee shall appropriately adjust the number and kind of shares of 
Stock subject to the Option and such option price; provided, however, that no 
such adjustment shall give Grantee any additional benefits under the Option.

    In the event of any Corporate Transaction or an event giving rise to a 
Change in Control, the Option shall be fully vested, nonforfeitable and 
become exercisable as of the date of the Change in Control or Corporate 
Transaction or as otherwise determined in accordance with Section 5.5(c) of 
the Plan.  However, in the case of a Corporate Transaction, the Committee may 
determine that the Option will not be so accelerated if and to the extent 
(i) such Option is either to be assumed by the successor or parent thereof or 
to be replaced with a comparable Option to purchase shares of the capital 
stock of the successor corporation or parent thereof, or (ii) such Option is 
to be replaced with a cash incentive program of the successor corporation 
that preserves the option spread existing at the time of the Corporate 
Transaction and provides for subsequent payment in accordance with the same 
vesting schedule applicable to such Option.

    In the event of a Corporate Transaction described in clauses (i) or (ii) of
Section 5.5(b) of the Plan, the Committee may, upon no less than 60 days notice
to the optionee (an "Acceleration Notice") determine that such optionee's
Options will terminate as of the effective date of such Corporate Transaction,
in which event such Options shall be fully vested, nonforfeitable and become
exercisable immediately as of the date of such Acceleration Notice.  In the
event of a Change in Control or Corporate Transaction described in clauses
(a)(i), (a)(ii) and (b)(iii) of Section 5.5 of the Plan or in the event the
Acceleration Notice is not timely given, the Option shall remain exercisable for
the remaining term of the Option notwithstanding the provisions of Article V of
the Plan, subject to any limitations thereto which may be applicable to
Incentive Stock Options.  In the event of a Corporate Transaction described in
clauses (a)(iii), (b)(i) or (b)(ii) of Section 5.5 of the Plan, which is
preceded by a timely Acceleration Notice, the Option shall terminate as of the
effective date of the Corporate Transaction described therein.  In no event
shall the Option be exercised after the expiration of the Option Term.

6.  FAIR MARKET VALUE.

    As used herein, the term "Fair Market Value" shall mean:

    (a)  If the Common Stock is listed on any established stock exchange or a
national market system, including, without limitation, the Nasdaq National
Market, its fair market value shall be the closing selling price for such stock
on the principal securities exchange or national market system on which the
Common Stock is at the time listed for trading.  If there are no sales of Common
Stock on that date, then the closing selling price for the Common Stock on the
next preceding day for which such closing selling price is quoted shall be
determinative of fair market value; or

    (b)  If the Common Stock is not traded on an exchange or a national 
market system, its fair market value shall be determined in good faith by the 
Committee, possibly based upon, but not limited to, a fair market value 
concept averaged over the twenty (20) trading days (or five (5) trading days 
if the Common Stock is traded on the Nasdaq 


Exhibit 10.35.2                       3
<PAGE>

SmallCap Market or a similar market system) preceding the Date of Grant or 
other relevant date, and such determination shall be conclusive and binding 
on all persons.

    In no event shall the Fair Market Value equal less than the par value of 
the Common Stock. 

7.  NO RIGHTS AS SHAREHOLDERS.

    Grantee shall have no rights as a shareholder with respect thereto unless 
and until certificates for shares of Common Stock are issued to him or her.

8.  NON-TRANSFERABILITY OF OPTION.

    During Grantee's lifetime, this Option shall be exercisable only by 
Grantee or his or her guardian or legal representative.  

9.  EMPLOYMENT NOT AFFECTED.

    The grant of the Option hereunder shall not be construed as conferring on 
Grantee any right to continued employment, and Grantee's employment may be 
terminated without regard to the effect which such action might have upon him 
as a holder of this Option.

10. AMENDMENT OF OPTION.

    The Option may be amended by the Committee at any time (i) if the 
Committee determines, in its sole discretion, that amendment is necessary or 
advisable in light of any addition to or change in the Code or in the 
regulations issued thereunder, or any federal or state securities law or 
other law of regulation, which change occurs after the Date of Grant and by 
its terms applies to the Option; or (ii) other than in the circumstances 
described in clause (i), with the consent of Grantee.

11. NOTICE.

    Any notice to the Company provided for in this instrument shall be 
addressed to it in care of its Secretary at its executive offices and any 
notice to Grantee shall be addressed to Grantee at the current address shown 
on the payroll records of the Employer.  Any notice shall be deemed to be 
duly given if and when properly addressed and posted by registered or 
certified mail, postage prepaid.  

12. INCORPORATION OF PLAN BY REFERENCE. 

    The Option is granted pursuant to the Plan, the terms and definitions of 
which are incorporated herein by reference, and the Option shall in all 
respects by interpreted in accordance with the Plan.

13. GOVERNING LAW.

    To the extent that federal law shall not be held to have preempted local 
law, this Option shall be governed by the laws of the State of Delaware.  If 
any provision of the Option shall be held invalid or unenforceable, the 
remaining provisions hereof shall continue in full force and effect.

    IN WITNESS WHEREOF, the Company has caused its duly authorized officer to 
execute this Grant of Incentive Stock Option, and Grantee has placed his or 
her signature hereon, effective as of the Date of Grant.

     THIS GRANT, dated as of the date of grant first stated above (the "Date 
of Grant"), is delivered by NRG Generating (U.S.) Inc. (the "Company") to 
_____________________ (the "Grantee"), who is an Employee of the Company or a

     WHEREAS, the Board of Directors of the Company (the "Board") on April 
20, 1998, adopted the NRG Generating (U.S.) Inc. 1998 Stock Option Plan (the 
"Plan") effective as of that date;

     WHEREAS, the Plan provides for the granting of Nonqualified Stock 
Options by the Committee to directors of the Company, officers and key 
employees of the Company and its Subsidiaries and certain other individuals 
who have the capability of making or who have made a substantial contribution 
to the Company to purchase shares of the Common Stock of the Company (the 
"Stock"), in accordance with the terms and provisions thereof; and

     WHEREAS, the Committee considers Grantee to be a person who is eligible 
for a grant of Nonqualified Stock Options under the Plan, and has determined 
that it would be in the best interest of the Company to grant the 
Nonqualified Stock Options documented herein.

     NOW THEREFORE, the parties hereto, intending to be legally bound hereby, 
agree as follows:

1.  GRANT OF OPTION.

    Subject to the terms and conditions hereinafter set forth, the Company, 
with the approval and at the direction of the Committee, hereby grants to 
Grantee, as of the Date of Grant, an option to purchase up to __________ 
shares of Stock at a price of $___________ per share.  The shares of stock 
purchasable upon exercise of the Option are hereinafter sometimes referred to 
as the "Option Shares."  The Option is intended by the parties hereto to be, 
and shall be treated as, a Nonqualified Stock Option which is not subject to 
the provisions of Code Section 422.

2.  INSTALLMENT EXERCISE.

    Subject to such further limitations as are provided herein, the Option 
shall become exercisable in three (3) installments, Grantee having the right

<PAGE>

3.  TERMINATION OF OPTION.

    (a)  The Option and all rights hereunder with respect thereto, to the 
extent such rights shall not have been exercised, shall terminate and become 
null and void after the expiration of ten (10) years from the Date of Grant 
(the "Option Term").

    (b)  Upon the occurrence of Grantee's ceasing for any reason to be 
employed by the Company, the Option, to the extent not previously exercised, 
shall terminate and become null and void, subject to the further provisions 
of this Section 3(b), which shall apply based upon the circumstances of such 
termination of employment.  Upon termination of Grantee's employment by 
reason of Disability or death, all unexercised portions of the Option shall 
become immediately exercisable and the Option may be exercised during the 
period beginning upon such termination and ending one year after such date. 
In the event of any other termination of Grantee's employment, the Option may 
be exercised during the three-month period following the date of termination, 
but only to the extent that the Option was outstanding and exercisable on the 
date of such termination. In no event, however, shall any such period extend 
beyond the Option Term.

    (c)  In the event of Grantee's death, the Option may be exercised by 
Grantee's legal representative(s) as and to the extent that the Option would 
otherwise have been exercisable by Grantee, subject to the provisions of  
Section 3(b) hereof.

    (d)  A transfer of Grantee's employment between the Company, its Parents, 
Subsidiaries or affiliates, shall not be deemed to be a termination of 
Grantee's employment.

    (e)  Notwithstanding any other provisions set forth herein or in the 
Plan, if Grantee shall: (i) commit any act of malfeasance or wrongdoing 
affecting the Company, its Parents or Subsidiaries, (ii) breach any covenant 
not to compete, or employment contract, with the Company, its Parents or 
Subsidiaries, or (iii) engage in conduct that would warrant Grantee's 
discharge for cause (excluding general dissatisfaction with the performance 
of Grantee's duties, but including any act of disloyalty or any conduct 
clearly tending to bring discredit upon the Company, its Parents or 
Subsidiaries), any unexercised portion of the Option shall immediately 
terminate and be void.

4.  EXERCISE OF OPTIONS.

    (a)  Grantee may exercise the Option with respect to all or any part of 
the number of Option Shares that are exercisable hereunder by giving the 
Secretary of the Company written notice of intent to exercise.  The notice of 
exercise shall specify the number of Option Shares as to which the Option is 
to be exercised and date of exercise thereof, which date shall be at least 
five (5) days after the signing of such notice unless an earlier time shall 
have been mutually agreed upon.

    (b)  Full payment (in U.S. dollars) by Grantee of the Option Price for 
Option Shares purchased shall be made on or before the exercise date 
specified in the notice of exercise in cash or as the Company may otherwise 
permit as further set forth in the Plan.  On the exercise date specified in 
Grantee's notice or as soon thereafter as is practicable, the Company shall 
cause to be delivered to Grantee, a certificate or certificates for the 
Option Shares then being purchased (out of theretofore unissued Stock or 
reacquired Stock, as the Company may elect) upon full payment for such Option 
Shares.  The obligation of the Company to deliver Stock shall, however, be 
subject to the condition that if at any time the Committee shall determine in 
its discretion that the listing, registration or qualification of the Option 
or the Option Shares upon any securities exchange or under any state or 
federal law, or the consent or approval of any governmental regulatory body, 
is necessary or desirable as a condition of, or in connection with, the 
Option or the issuance or purchase of Stock thereunder, the Option may not be 
exercised in whole or in part unless such listing, registration, 
qualification, consent or approval shall have been effected or obtained free 
of any conditions not acceptable to the Committee.


Exhibit 10.35.3                        2

<PAGE>

    (c)  If Grantee fails to pay for any of the Option Shares specified in 
such notice or fails to accept delivery thereof, Grantee's right to purchase 
such Option Shares may be terminated by the Company or the exercise of the 
Option may be ignored, as the Committee in its sole discretion may determine. 
The date specified in Grantee's notice as the date of exercise shall be 
deemed the date of exercise of the Option, provided that payment in full for 
the Option Shares to be purchased upon such exercise shall have been received 
by such date.

5.  ADJUSTMENT OF AND CHANGES IN STOCK.

    In the event of a reorganization, recapitalization, change of shares, 
stock split, spin-off, stock dividend, reclassification, subdivision, or 
combination of shares, merger, consolidation, rights offering, or any other 
change in the corporate structure of shares of capital stock of the Company, 
the Committee shall appropriately adjust the number and kind of shares of 
Stock subject to the Option and such option price; provided, however, that no 
such adjustment shall give Grantee any additional benefits under the Option.

    In the event of any Corporate Transaction or an event giving rise to a 
Change in Control, the Option shall be fully vested, nonforfeitable and 
become exercisable as of the date of the Change in Control or Corporate 
Transaction or as otherwise determined in accordance with Section 5.5(c) of 
the Plan.  However, in the case of a Corporate Transaction, the Committee may 
determine that the Option will not be so accelerated if and to the extent (i) 
such Option is either to be assumed by the successor or parent thereof or to 
be replaced with a comparable Option to purchase shares of the capital stock 
of the successor corporation or parent thereof, or (ii) such Option is to be 
replaced with a cash incentive program of the successor corporation that 
preserves the option spread existing at the time of the Corporate Transaction 
and provides for subsequent payment in accordance with the same vesting 
schedule applicable to such Option. In the event of a Corporate Transaction 
described in clauses (i) or (ii) of Section 5.5(b) of the Plan, the Committee 
may, upon no less than 60 days notice to the optionee (an "Acceleration 
Notice") determine that such optionee's Options will terminate as of the 
effective date of such Corporate Transaction, in which event such Options 
shall be fully vested, nonforfeitable and become exercisable immediately as 
of the date of such Acceleration Notice.  In the event of a Change in Control 
or Corporate Transaction described in clauses (a)(i), (a)(ii) and (b)(iii) of 
Section 5.5 of the Plan or in the event the Acceleration Notice is not timely 
given, the Option shall remain exercisable for the remaining term of the 
Option notwithstanding the provisions of Article V of the Plan, subject to 
any limitations thereto which may be applicable to Incentive Stock Options.  
In the event of a Corporate Transaction described in clauses (a)(iii), (b)(i) 
or (b)(ii) of Section 5.5 of the Plan, which is preceded by a timely 
Acceleration Notice, the Option shall terminate as of the effective date of 
the Corporate Transaction described therein.  In no event shall the Option be 
exercised after the expiration of the Option Term.

6.  NO RIGHTS AS SHAREHOLDERS.

    Grantee shall have no rights as a shareholder with respect thereto unless 
and until certificates for shares of Common Stock are issued to him or her.

7.  NON-TRANSFERABILITY OF OPTION.

    During Grantee's lifetime, this Option shall be exercisable only by 
Grantee or his or her guardian or legal representative.

8.  EMPLOYMENT NOT AFFECTED.

    The grant of the Option hereunder shall not be construed as conferring on 
Grantee any right to continued employment, and Grantee's employment may be 
terminated without regard to the effect which such action might have upon him 
as a holder of this Option.

9.  AMENDMENT OF OPTION.

    The Option may be amended by the Committee at any time (i) if the 
Committee determines, in its sole discretion, that amendment is necessary or 
advisable in light of any addition to or change in the Code or in the 
regulations issued thereunder, or any federal or state securities law or 
other law of regulation, which change occurs after the Date of Grant and by 


Exhibit 10.35.3                        3

<PAGE>

its terms applies to the Option; or (ii) other than in the circumstances 
described in clause (i), with the consent of Grantee.

10.  NOTICE.

     Any notice to the Company provided for in this instrument shall be 
addressed to it in care of its Secretary at its executive offices and any 
notice to Grantee shall be addressed to Grantee at the current address shown 
on the payroll records of the Employer.  Any notice shall be deemed to be 
duly given if and when properly addressed and posted by registered or 
certified mail, postage prepaid.  

11.  INCORPORATION OF PLAN BY REFERENCE.

     The Option is granted pursuant to the Plan, the terms and definitions of 
which are incorporated herein by reference, and the Option shall in all 
respects by interpreted in accordance with the Plan.

12.  GOVERNING LAW.

     To the extent that federal law shall not be held to have preempted local 
law, this Option shall be governed by the laws of the State of Delaware.  If 
any provision of the Option shall be held invalid or unenforceable, the 
remaining provisions hereof shall continue in full force and effect.

                           GRANT OF NONEMPLOYEE DIRECTOR
                             NONQUALIFIED STOCK OPTION


DATE OF GRANT: ______________________

     THIS GRANT, dated as of the date of grant first stated above (the "Date 
of Grant"), is delivered by NRG Generating (U.S.) Inc. (the "Company") to 
_____________________ (the "Grantee"), who is a director of the Company who 
is not an Employee of the Company or a Subsidiary.

     WHEREAS, the Board of Directors of the Company (the "Board") on April 
20, 1998 adopted the NRG Generating (U.S.) Inc. 1998 Stock Option Plan (the 
"Plan") effective as of that date;

     WHEREAS, the Plan provides for the granting of Nonqualified Stock 
Options by the Committee to directors of the Company to purchase shares of 
the Common Stock of the Company (the "Stock"), in accordance with the terms 
and provisions thereof; and

     WHEREAS, the Committee considers Grantee to be a person who is eligible 
for a grant of Nonqualified Stock Options under the Plan, and has determined 
that it would be in the best interest of the Company to grant the 
Nonqualified Stock Options documented herein.

     NOW THEREFORE, the parties hereto, intending to be legally bound hereby, 
agree as follows:

1.   GRANT OF OPTION.

     Subject to the terms and conditions hereinafter set forth, the Company, 
with the approval and at the direction of the Committee, hereby grants to 
Grantee, as of the Date of Grant, an option to purchase up to __________ 
shares of Stock at a price of $___________ per share.  The shares of stock 
purchasable upon exercise of the Option are hereinafter sometimes referred to 
as the "Option Shares."  The Option is intended by the parties hereto to be, 
and shall be treated as, a Nonqualified Stock Option which is not subject to 
the provisions of Code Section 422.

2.   INSTALLMENT EXERCISE.

     Subject to such further limitations as are provided herein, the Option 
shall become exercisable in three (3) installments, Grantee having the right 
hereunder to purchase from the Company the following number of Option Shares 
upon exercise of the Option, on and after the following dates, in cumulative 
fashion:

     (i)  on and after the first anniversary of the Date of Grant up to 
one-third (ignoring fractional shares) of the total number of Option Shares;

     (ii)  on and after the second anniversary of the Date of Grant, up to an 
additional one-third (ignoring fractional shares) of the total number of 
Option Shares; and


Exhibit 10.35.4

<PAGE>

     (iii)  on and after the third anniversary of the Date of Grant, the 
remaining Option Shares.

3.   TERMINATION OF OPTION.

     (a)  The Option and all rights hereunder with respect thereto, to the 
extent such rights shall not have been exercised, shall terminate and become 
null and void after the expiration of ten (10) years from the Date of Grant 
(the "Option Term").

     (b)  When the Grantee ceases to be a director of the Company, the 
Option, to the extent not previously exercised, shall terminate and become 
null and void immediately upon the Separation Date, except in a case where 
the Grantee's service as a director of the Company ceases by reason of 
Disability or death or otherwise as follows.  If the Grantee ceases to be a 
director of the Company by reason of Disability or death, all unexercised 
portions of the Option shall become immediately exercisable and the Option 
may be exercised during the period beginning upon such termination and ending 
one year after such date. In no event, however, shall any such period extend 
beyond the Option Term.  If the Participant's service as a director of the 
Company terminates for any other reason prior to the exercise of all portions 
of the Option, the Participant shall have the right within three (3) months 
of his Separation Date, but not beyond the expiration date of the Option, to 
exercise such unexercised portions of the Option.

     (c)  In the event of Grantee's death, the Option may be exercised by 
Grantee's legal representative(s) as and to the extent that the Option would 
otherwise have been exercisable by Grantee, subject to the provisions of  
Section 3(b) hereof.

     (d)  Notwithstanding any other provisions set forth herein or in the 
Plan, if Grantee shall: (i) commit any act of malfeasance or wrongdoing 
affecting the Company, its Parents or Subsidiaries, or (ii) engage in conduct 
that would warrant Grantee's removal for cause (excluding general 
dissatisfaction with the performance of Grantee's duties, but including any 
act of disloyalty or any conduct clearly tending to bring discredit upon the 
Company, its Parents or Subsidiaries), any unexercised portion of the Option 
shall immediately terminate and be void.

4.   EXERCISE OF OPTIONS.

     (a)  Grantee may exercise the Option with respect to all or any part of 
the number of Option Shares that are exercisable hereunder by giving the 
Secretary of the Company written notice of intent to exercise.  The notice of 
exercise shall specify the number of Option Shares as to which the Option is 
to be exercised and date of exercise thereof, which date shall be at least 
five (5) days after the signing of such notice unless an earlier time shall 
have been mutually agreed upon.

     (b)  Full payment (in U.S. dollars) by Grantee of the Option Price for 
Option Shares purchased shall be made on or before the exercise date 
specified in the notice of exercise in cash or as the Company may otherwise 
permit as further set forth in the Plan.  On the exercise date specified in 
Grantee's notice or as soon thereafter as is practicable, the Company shall 
cause to be delivered to Grantee, a certificate or certificates for the 
Option Shares then being purchased (out of theretofore unissued Stock or 
reacquired Stock, as the Company may elect) upon full payment for such Option 
Shares.  The obligation of the Company to deliver Stock shall, however, be 
subject to the condition that if at any time the Committee shall determine in 
its discretion that the listing, registration or qualification of the Option 
or the Option Shares upon any securities exchange or under any state or 
federal law, or the consent or approval of any governmental regulatory body, 
is necessary or desirable as a condition of, or in connection with, the 
Option or the issuance or purchase of Stock thereunder, the Option may not be 
exercised in whole or in part unless such listing, registration, 
qualification, consent or approval shall have been effected or obtained free 
of any conditions not acceptable to the Committee.

     (c)  If Grantee fails to pay for any of the Option Shares specified in 
such notice or fails to accept delivery thereof, Grantee's right to purchase 
such


Exhibit 10.35.4                        2

<PAGE>

Option Shares may be terminated by the Company or the exercise of the Option 
may be ignored, as the Committee in its sole discretion may determine. The 
date specified in Grantee's notice as the date of exercise shall be deemed 
the date of exercise of the Option, provided that payment in full for the 
Option Shares to be purchased upon such exercise shall have been received by 
such date.

5.   ADJUSTMENT OF AND CHANGES IN STOCK.

     In the event of a reorganization, recapitalization, change of shares, 
stock split, spin-off, stock dividend, reclassification, subdivision, or 
combination of shares, merger, consolidation, rights offering, or any other 
change in the corporate structure of shares of capital stock of the Company, 
the Committee shall appropriately adjust the number and kind of shares of 
Stock subject to the Option and such option price; provided, however, that no 
such adjustment shall give Grantee any additional benefits under the Option.

     In the event of any Corporate Transaction or an event giving rise to a 
Change in Control, the Option shall be fully vested, nonforfeitable and 
become exercisable as of the date of the Change in Control or Corporate 
Transaction or as otherwise determined in accordance with Section 5.5(c) of 
the Plan.  However, in the case of a Corporate Transaction, the Committee may 
determine that the Option will not be so accelerated if and to the extent (i) 
such Option is either to be assumed by the successor or parent thereof or to 
be replaced with a comparable Option to purchase shares of the capital stock 
of the successor corporation or parent thereof, or (ii) such Option is to be 
replaced with a cash incentive program of the successor corporation that 
preserves the option spread existing at the time of the Corporate Transaction 
and provides for subsequent payment in accordance with the same vesting 
schedule applicable to such Option.

     In the event of a Corporate Transaction described in clauses (i) or (ii) 
of Section 5.5(b) of the Plan, the Committee may, upon no less than 60 days 
notice to the optionee (an "Acceleration Notice") determine that such 
optionee's Options will terminate as of the effective date of such Corporate 
Transaction, in which event such Options shall be fully vested, 
nonforfeitable and become exercisable immediately as of the date of such 
Acceleration Notice.  In the event of a Change in Control or Corporate 
Transaction described in clauses (a)(i), (a)(ii) and (b)(iii) of Section 5.5 
of the Plan or in the event the Acceleration Notice is not timely given, the 
Option shall remain exercisable for the remaining term of the Option 
notwithstanding the provisions of Article V of the Plan, subject to any 
limitations thereto which may be applicable to Incentive Stock Options.  In 
the event of a Corporate Transaction described in clauses (a)(i)(iii), b(i) 
or (b)(ii) of Section 5.5 of the Plan, which is preceded by a timely 
Acceleration Notice, the Option shall terminate as of the effective date of 
the Corporate Transaction described therein.  In no event shall the Option be 
exercised after the expiration of the Option Term.

6.   NO RIGHTS AS SHAREHOLDERS.

     Grantee shall have no rights as a shareholder with respect thereto 
unless and until certificates for shares of Common Stock are issued to him or 
her.

7.   NON-TRANSFERABILITY OF OPTION.

     During Grantee's lifetime, this Option shall be exercisable only by 
Grantee or his or her guardian or legal representative.  

8.   AMENDMENT OF OPTION.

     The Option may be amended by the Committee at any time (i) if the Committee
determines, in its sole discretion, that amendment is necessary or advisable in
light of any addition to or change in the Code or in the regulations issued
thereunder, or any federal or state securities law or other law of regulation,
which change occurs after the Date of Grant and by its terms applies to the
Option; or (ii) other than in the circumstances described in clause (i), with
the consent of Grantee.

     WHEREAS, the Board of Directors of the Company (the "Board") on April 20,
1998, adopted the NRG Generating (U.S.) Inc. 1998 Stock Option Plan (the "Plan")
effective as of that date;

     WHEREAS, the Plan provides for the granting of Nonqualified Stock Options
by the Committee to directors of the Company, officers and key employees of the
Company and its Subsidiaries and certain other individuals who have the
capability of making or who have made a substantial contribution to the Company

     WHEREAS, the Committee considers Grantee to be a person who is eligible for
a grant of Nonqualified Stock Options under the Plan, and has determined that it
would be in the best interest of the Company to grant the Nonqualified Stock
Options documented herein.

      NOW THEREFORE, the parties hereto, intending to be legally bound 
hereby, agree as follows:

1.   GRANT OF OPTION.

     Subject to the terms and conditions hereinafter set forth, the Company, 
with the approval and at the direction of the Committee, hereby grants to 
Grantee, as of the Date of Grant, an option to purchase up to __________ 
shares of Stock at a price of $___________ per share.  The shares of stock 
purchasable upon exercise of the Option are hereinafter sometimes referred to

3.   TERMINATION OF OPTION.

     (a)  The Option and all rights hereunder with respect thereto, to the 
extent such rights shall not have been exercised, shall terminate and become 
null and void after the expiration of ten (10) years from the Date of Grant 
(the "Option Term").

[    (b)  Upon the occurrence of Grantee's ceasing for any reason to be 
providing service to the Company, its Parents, Subsidiaries or affiliates, 
the Option, to the extent not previously exercised, shall terminate and 
become null and void immediately upon the Separation Date, except in a case 
where the termination of Grantee's services is by reason of retirement,

during the period beginning upon such termination and ending one year after 
such date.  Upon termination of Grantee's services, the Option may be 
exercised during the three-month period following the date of retirement, but 
only to the extent that the Option was outstanding and exercisable on the 
date of such retirement. In no event, however, shall any such period extend 
beyond the Option Term.]

     (c)  In the event of Grantee's death, the Option may be exercised by 
Grantee's legal representative(s) as and to the extent that the Option would 
otherwise have been exercisable by Grantee, subject to the provisions of  
Section 3(b) hereof.

     (d)  Notwithstanding any other provisions set forth herein or in the 
Plan, if Grantee shall: (i) commit any act of malfeasance or wrongdoing 
affecting the Company, its Parents, its Subsidiaries, (ii) breach any 
covenant not to compete, or employment contract, with the Company, its 
Parents, Subsidiaries or affiliates, or (iii) engage in conduct that would 
warrant Grantee's discharge for cause if he were an employee of the Company 
(excluding general dissatisfaction with the performance of Grantee's duties, 
but including any act of disloyalty or any conduct clearly tending to bring 
discredit upon the Company, its Parents, Subsidiaries or affiliates), any 
unexercised portion of the Option shall immediately terminate and be void.

4.   EXERCISE OF OPTIONS.

     (a)  Grantee may exercise the Option with respect to all or any part of 
the number of Option Shares that are exercisable hereunder by giving the 
Secretary of the Company written notice of intent to exercise.  The notice of 
exercise shall specify the number of Option Shares as to which the Option is 
to be exercised and date of exercise thereof, which date shall be at least 
five (5) days after the signing of such notice unless an earlier time shall 
have been mutually agreed upon.

     (b)  Full payment (in U.S. dollars) by Grantee of the Option Price for 
Option Shares purchased shall be made on or before the exercise date 
specified in the notice of exercise in cash or as the Company may otherwise 
permit as further set forth in the Plan.  On the exercise date specified in 
Grantee's notice or as soon thereafter as is practicable, the Company shall 
cause to be delivered to Grantee, a certificate or certificates for the 
Option Shares then being purchased (out of theretofore unissued Stock or 
reacquired Stock, as the Company may elect) upon full payment for such Option 
Shares.  The obligation of the Company to deliver Stock shall, however, be 
subject to the condition that if at any time the Committee shall determine in 
its discretion that the listing, registration or qualification of the Option 
or the Option Shares upon any securities exchange or under any state or 
federal law, or the consent or approval of any governmental regulatory body, 
is necessary or desirable as a condition of, or in connection with, the 
Option or the issuance or purchase of Stock thereunder, the Option may not be 
exercised in whole or in part unless such listing, registration, 
qualification, consent or approval shall have been effected or obtained free 
of any conditions not acceptable to the Committee.

     (c)  If Grantee fails to pay for any of the Option Shares specified in 
such notice or fails to accept delivery thereof, Grantee's right to purchase 
such Option Shares may be terminated by the Company 


Exhibit 10.35.5                       2
<PAGE>

or the exercise of the Option may be ignored, as the Committee in its sole 
discretion may determine.  The date specified in Grantee's notice as the date 
of exercise shall be deemed the date of exercise of the Option, provided that 
payment in full for the Option Shares to be purchased upon such exercise 
shall have been received by such date.

5.   ADJUSTMENT OF AND CHANGES IN STOCK.

     In the event of a reorganization, recapitalization, change of shares, 
stock split, spin-off, stock dividend, reclassification, subdivision, or 
combination of shares, merger, consolidation, rights offering, or any other 
change in the corporate structure of shares of capital stock of the Company, 
the Committee shall appropriately adjust the number and kind of shares of 
Stock subject to the Option and such option price; provided, however, that no 
such adjustment shall give Grantee any additional benefits under the Option.

     [In the event of any Corporate Transaction or an event giving rise to a 
Change in Control, the Option shall be fully vested, nonforfeitable and 
become exercisable as of the date of the Change in Control or Corporate 
Transaction or as otherwise determined in accordance with Section 5.5(c) of 
the Plan.  However, in the case of a Corporate Transaction, the Committee may 
determine that the Option will not be so accelerated if and to the extent 
(i) such Option is either to be assumed by the successor or parent thereof or 
to be replaced with a comparable Option to purchase shares of the capital 
stock of the successor corporation or parent thereof, or (ii) such Option is 
to be replaced with a cash incentive program of the successor corporation 
that preserves the option spread existing at the time of the Corporate 
Transaction and provides for subsequent payment in accordance with the same 
vesting schedule applicable to such Option.

     In the event of a Corporate Transaction described in clauses (i) or (ii) 
of Section 5.5(b) of the Plan, the Committee may, upon no less than 60 days 
notice to the optionee (an "Acceleration Notice") determine that such 
optionee's Options will terminate as of the effective date of such Corporate 
Transaction, in which event such Options shall be fully vested, 
nonforfeitable and become exercisable immediately as of the date of such 
Acceleration Notice.  In the event of a Change in Control or Corporate 
Transaction described in clauses (a)(i), (a)(ii) and (b)(iii) of Section 5.5 
of the Plan or in the event the Acceleration Notice is not timely given, the 
Option shall remain exercisable for the remaining term of the Option 
notwithstanding the provisions of Article V of the Plan, subject to any 
limitations thereto which may be applicable to Incentive Stock Options.  In 
the event of a Corporate Transaction described in clauses (a)(iii), (b)(i) or 
(b)(ii) of Section 5.5 of the Plan, which is preceded by a timely 
Acceleration Notice, the Option shall terminate as of the effective date of 
the Corporate Transaction described therein.  In no event shall the Option be 
exercised after the expiration of the Option Term.]

6.   NO RIGHTS AS SHAREHOLDERS.

     Grantee shall have no rights as a shareholder with respect thereto 
unless and until certificates for shares of Common Stock are issued to him or 
her.

7.   NON-TRANSFERABILITY OF OPTION.

     During Grantee's lifetime, this Option shall be exercisable only by 
Grantee or his or her guardian or legal representative.

8.   EMPLOYMENT NOT AFFECTED.

     The grant of the Option hereunder shall not be construed as conferring 
on Grantee any right to continue providing services to the Company, and 
Grantee's provision of services to the Company may be terminated without 
regard to the effect which such action might have upon him as a holder of 
this Option.


Exhibit 10.35.5                       3
<PAGE>

9.   AMENDMENT OF OPTION.

     The Option may be amended by the Committee at any time (i) if the 
Committee determines, in its sole discretion, that amendment is necessary or 
advisable in light of any addition to or change in the Code or in the 
regulations issued thereunder, or any federal or state securities law or 
other law of regulation, which change occurs after the Date of Grant and by 
its terms applies to the Option; or (ii) other than in the circumstances 
described in clause (i), with the consent of Grantee.

10.  NOTICE.

     Any notice to the Company provided for in this instrument shall be 
addressed to it in care of its Secretary at its executive offices and any 
notice to Grantee shall be addressed to Grantee at the current address shown 
on the payroll records of the Employer.  Any notice shall be deemed to be 
duly given if and when properly addressed and posted by registered or 
certified mail, postage prepaid.  

11.  INCORPORATION OF PLAN BY REFERENCE.

     The Option is granted pursuant to the Plan, the terms and definitions of 
which are incorporated herein by reference, and the Option shall in all 
respects by interpreted in accordance with the Plan.

12.  GOVERNING LAW.

     To the extent that federal law shall not be held to have preempted local 
law, this Option shall be governed by the laws of the State of Delaware.  If 
any provision of the Option shall be held invalid or unenforceable, the 
remaining provisions hereof shall continue in full force and effect.

     IN WITNESS WHEREOF, the Company has caused its duly authorized officer 
to execute this Grant of Nonqualified Stock Option, and Grantee has placed 
his or her signature hereon, effective as of the Date of Grant.
