   DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

         This Annual Report includes historical information as well as
statements regarding our future expectations. The statements regarding the
future (referred to as "forward-looking statements") include among other things
statements about energy markets in 2000; cost reduction targets; return on
capital goals; development, production and acceptance of new products and
process technologies; ongoing and planned capacity additions and expansions and
joint ventures. Important factors that could cause actual results to differ
materially from those discussed in such forward-looking statements include:
supply/demand for our products, competitive pricing pressures, weather patterns,
changes in industry laws and regulations, competitive technology, failure to
achieve our cost reduction targets or complete construction projects on schedule
and Year 2000 computer related difficulties. We believe in good faith that the
forward-looking statements in this Annual Report have a reasonable basis,
including without limitation, management's examination of historical operating
trends, data contained in our records and other data available from third
parties, but such forward looking statements are not guarantees of future
performance and actual results may differ materially from any results expressed
or implied by such forward looking statements.

ITEM 1.  BUSINESS

GENERAL

         Trigen Energy Corporation was incorporated under the laws of Delaware
on November 21, 1986. In this Annual Report, the pronouns "Trigen", "we" and
"our" refer to Trigen Energy Corporation together with its wholly owned
subsidiaries and the Trigen-Cinergy joint venture subsidiaries ( See "Revenue
Growth/Acquisitions" below). We seek to produce and deliver the maximum economic
value of energy and minimum pollution from each unit of fuel burned. Our
approach is to use fuel to produce electricity or mechanical power, and in the
same process also produce thermal energy (heating and/or cooling). In some
locations our facilities are connected to pipeline networks which distribute our
thermal energy to multiple buildings (district energy), in others our facilities
are located adjacent to industrial plants and dedicated to the needs of those
plants (onsite energy).

         On January 19, 2000, Elyo, an energy subsidiary of the Suez Lyonnaise
des Eaux Group, T Acquisition Corp., an indirect wholly owned subsidiary of
Elyo, and the Company entered into a merger agreement, pursuant to which Elyo,
through T Acquisition Corp., would acquire all of the outstanding shares of
Trigen Common Stock it did not already own. On February 28, 2000, T Acquisition
Corp. commenced a tender offer to purchase any and all of the issued and
outstanding shares of Common Stock of Trigen at a price of $23.50 per share, net
to the seller in cash, without interest thereon. The tender offer is being made
pursuant to the terms of the merger agreement. On March 27, 2000, Elyo announced
the completion of the tender offer. As of that date, Elyo had beneficial
ownership of approximately 96% of Trigen's stock.

         On January 19, 2000, Richard E. Kessel, formerly executive vice
president, chief operating officer and a director of Trigen, was elected
president and chief executive officer. Mr. Kessel joined Trigen in 1993, when
the Company acquired United Thermal Corporation of which he was CEO. He also
serves as Chairman of the Board's executive committee. Mr. Kessel succeeds
Thomas R. Casten who resigned the position of President and Chief Executive
Officer to pursue other interests.

         We operate fourteen district energy systems serving urban customers and
seventeen single customer industrial/commercial energy projects. Our major
customers include industrial plants, electric utilities, commercial and office
buildings, government buildings, colleges and universities, hospitals,
residential complexes, hotels, sports arenas and convention centers. Our two
largest customers are Long Island Power Authority and Coors' Brewing Company
(See Note 2 to Consolidated Financial Statements Summary of Accounting Policies,
Revenue Recognition). A significant portion of our revenues and operating profit
from sales of thermal energy for non-industrial users is subject to seasonal
fluctuations (See Item 7 Management's Discussion and Analysis of Financial
Condition and Results of Operations).

         Our choice of fuels, technology, blend of heat, cooling, and power
produced, and distribution media are determined by local prices for fuel, prices
for conventionally generated energy products and the convertibility of existing
plant and equipment to more efficient cogeneration or trigeneration.
Cogeneration is the combined production of electricity and useful thermal energy
(heating OR cooling) by the sequential use of energy from one unit of fuel.
Trigeneration is the combined production of electricity and useful thermal
energy (heating AND cooling) from one unit of fuel. We develop, own, and operate
facilities that produce and deliver thermal energy to commercial, governmental,
and industrial customers in the form of steam, hot water, and/or chilled water.
Our plants use various technologies - gas turbines, diesel engines, boilers and
chillers - and various fuels, including natural gas, coal, oil, wood waste,
municipal solid waste, and industrial by-products or scrap.

         To complement our basic business and to enhance our ability to add
energy value, we have a separate technical product division that develops and
produces products that conserve energy or extract more value from steam or help
users


                                       2
<PAGE>

manage energy more efficiently. At present, this division offers steam pipeline
insulation products, which may be installed without removing pipe from the
ground and a low temperature thermal stratification fluid designed to lower the
freezing point of water thus increasing the efficiency of conventional chiller
plants. This division also produces back-pressure steam turbine generator sets
and power units. Our back-pressure turbines take the place of steam pressure
reducing valves and extract mechanical energy from the steam pressure reduction
process. We also provide total energy management services to building owners and
operators by providing operational services and management expertise with
respect to energy production, procurement and usage.

         Our cogeneration or trigeneration plants emit up to 95% less nitrous
oxides than the conventional electric generation they replace, and because of
greater energy efficiency, emit less than half as much carbon dioxide (an
ingredient in global warming) as would be produced by conventional production of
the same energy. When we burn bio-mass fuels in our plants we eliminate the need
to dispose of this waste in a landfill and we produce no more carbon dioxide
than if these wastes were allowed to decay in a landfill.

REVENUE GROWTH/ACQUISITIONS

         Our revenues have increased from approximately $1 million in 1987 (our
first full year of operation) to $280.4 million in 1999 through acquisitions and
internal growth. This Annual Report includes Consolidated Statements of
Operations, which report our revenues and operating income for the last three
fiscal years. Total assets at the end of 1999, 1998 and 1997 were $727.5
million, $618.2 million and $526.0 million respectively.

         We report the amount and percentage of our total revenue from thermal
energy sales and electric energy sales for the last three years in Item 7 of
this Annual Report ("Management's Discussion and Analysis of Financial Condition
and Results of Operations"). Our revenue from sales outside the United States
for the last three years was not material. We have not held a material amount of
assets outside the United States over the last three years.

         In 1995, we formed a limited partnership with a subsidiary of Tucson
Electric Power Company which purchased the energy systems of Coors' Brewing
Company and Coors Energy Company in Golden, Colorado. In September of 1998, we
purchased an additional 48% interest in that limited partnership from the
subsidiary of Tucson Electric and in June 1999 purchased the remaining 1%. We
now own 100% of those energy systems.

         In January 1998, we acquired Power Sources, Inc., which has been
renamed Trigen-BioPower, Inc. Trigen-BioPower operates seven biomass-to-energy
plants, producing steam for seven industrial customers from roughly 600,000 tons
per year of renewable biomass fuels, including wood residues, rice hulls, cotton
waste and paper mill sludge. As of December 1999, Trigen-BioPower has one
additional biomass plant under construction in St. Mary's, GA.

         We have an active joint venture with Cinergy Corp. to build, own and
operate cogeneration and trigeneration facilities in the United States, Canada,
the United Kingdom and Ireland. We own 51% of most of the Trigen-Cinergy joint
venture investments and 49% of others.

NEW ON SITE INDUSTRIAL/COMMERCIAL PROJECTS

         During 1999, we focused greater efforts on industrial customers. Since
the start of 1999, the Trigen-Cinergy joint venture began operating a district
cooling system Orlando, FL and took over large heating and cooling facilities in
Boca Raton, FL and College Park, MD. Trigen-Cinergy took over operations of
cogeneration facilities in Baltimore, MD and Ashtabula, OH. Trigen-Cinergy has
other projects currently under construction in Baltimore MD, St. Paul, MN,
Silver Grove, KY, and Rochester, NY. Trigen took over operations at a plant in
Decatur, AL and has a plant under construction in Denver, CO. We intend to
continue these efforts in the future and will selectively pursue electricity and
sales to the grid where that electricity is a by-product of efficient heat and
cooling production.

         Internationally, we are prepared to pursue selected opportunities in
Canada, Mexico and Central America or other countries where our customers have
facilities that favor a power project with high efficiency, reliability and
waste heat recovery. Trigen has one new plant under construction in Tampico,
Mexico.

BUSINESS STRATEGY

         We are a thermal sciences company. We seek ways to reduce fossil fuel
usage with cost effective efficiency. Our mission is to provide heating, cooling
and electricity with half the fossil fuel and half the pollution of conventional
generation. We use our expertise in thermodynamic engineering and proprietary
trigeneration processes to convert fuel to various forms of thermal energy and
electricity and achieve over 90% overall energy efficiency compared to the 33%
average efficiency of the U.S. electric utility industry in 1997.

         We believe industrial and institutional energy users will increasingly
turn to specialist energy companies, and will contract out all of their energy
and other utility needs in a process called outsourcing. We offer industrial
customers outsourcing options ranging from operating their systems to investing
our capital to provide new on site energy services and facilities. We specialize
in adding electric power generation sized to provide for the basic thermal
requirements of the


                                       3
<PAGE>

customer with normally wasted exhaust heat. We believe that our expertise in
developing and running cogeneration projects and projects which use biomass
fuels will be very attractive to these industrial customers.

         We see opportunities to expand our existing urban and industrial
systems to serve additional customers and the expanded needs of existing
customers. We will evaluate the acquisition of existing urban district energy or
industrial systems and the development of new systems to provide district energy
or independent power wherever our expertise provides a competitive advantage.

         Our strengths for the future include:

     -   STABLE CUSTOMER BASE. Our long term contracts (i.e. contracts with
         remaining terms in excess of 3 years) provide consolidated revenues of
         over $275 million per year for the five-year period 2000 through 2005
         and approximately $5.5 billion cumulatively for the period 2000 through
         2030 (before inflation, renewals and changes in consumption from 1999
         levels).

      -  TECHNICAL INNOVATION AND PLANT OPTIMIZATION. We have special expertise
         in the design and operation of energy systems which we use to optimize
         the efficiency of energy assets. Among other things, we have installed
         computerized, automated control systems, which place real-time
         production cost information in the hands of the plant operator, as well
         as back-pressure turbines, and thermal storage tanks that allow us to
         produce energy during off peak usage periods for use during peak
         periods.

     -   SERVICE RATE STRUCTURES ALIGN OUR INTERESTS WITH OUR CUSTOMERS. Our
         thermal service rate structures seek recovery of all fixed costs and a
         profit from fixed charges per month, which are adjusted with inflation,
         and then add a usage charge that is very close to our variable fuel and
         water cost. This lets us help customers to use less energy without
         reducing our gross margins and aligns our interests with customers.
         This feature has led to reductions of customer energy use per unit of
         product, or per square foot of building of as much as 20% in three
         years. Our price structures typically enable us to pass through to our
         customers fuel and most other commodity prices associated with
         providing energy services. For that reason, changes in such prices
         (which constitute approximately 49% of our costs) have little impact on
         our operating income.

     -   PROTECTING THE ENVIRONMENT. By extracting and delivering the maximum
         value of energy from fuel and by employing pollution control
         technology, we emit substantially less pollution than would result from
         conventional generation of the same heat, electricity, and cooling. The
         principal reasons for lower emissions are the fuel efficiency of
         cogeneration and trigeneration, the use of biomass, employment of
         refrigerants other than CFC's and wherever possible, thermal, chemical,
         and catalytic destruction of exhaust contaminants. Our modern
         cogeneration plants produce as little as 5% of the nitrogen oxide
         emissions associated with conventional generation.

     -   ENTREPRENEURIAL MISSION DRIVEN MANAGEMENT. Our senior management has
         extensive experience in developing and operating plants and processes
         that increase the value extracted from each unit of energy. These
         activities include the development and operation of district energy
         systems and cogeneration technologies.

OVERVIEW OF OUR PRODUCTS AND SERVICES

         The plants we operated at the end of 1999 have the total capacity to
produce 6,104 Megawatts of end use energy, of which approximately 86% is steam
or hot water, 7% is electricity and 7% is chilled water. These products are
distributed to customers through 156.4 miles (251.6 kilometers) of pipeline.
Separate pipelines are used for steam, hot water and chilled water.

         When we produce electricity with diesel or gas turbines, we recover the
exhaust heat to produce additional electricity, steam or hot water and/or
chilled water. Because demand for steam and hot water has daily and yearly
cycles, we cannot always use all the waste heat generated by our plants to
produce steam and hot water for immediate use. Trigeneration plants enable us to
recover and use waste heat to produce chilled water when heat demands are low.
We also store chilled water produced off-peak for sale during the peak usage
hours.

         By generating two or three energy products from a single fuel source,
cogeneration and trigeneration increase the value of useful energy output.
Average US electric-only generation converts 33% of fuel energy to high value
electricity, but exhausts 67% of the fuel energy as waste heat. Conventional
heat-only production converts 60% to 85% of the fuel energy to a much lower
value energy form -- typically steam, hot water, or hot air -- and fails to
extract the high value electric energy. Our approach is to combine the
generation of heat and power to maximize the value of energy produced from each
unit of fuel and minimize the resultant pollution.

         We balance the costs of producing and delivering these various energy
products, including the cost of capital, labor, line losses, and fuel with the
market value of the products to each user. The resulting plants seek to generate
profits after debt service by extracting more delivered value than conventional
single product generation.


                                       4
<PAGE>

         Reliability of service is a key. Most of our facilities have sufficient
heating capacity to generate peak loads with their largest production unit out
of service, and have the ability to use two or more different fuels.

         STEAM AND HOT WATER. We produce steam and/or hot water at substantially
all of our systems. Our customers use our steam and/or hot water for space
heating and hot water, for various industrial process uses, for cooling (by
powering on-site steam-driven chillers or absorption chillers), and for
humidification and sterilization.

         Currently, the States of Missouri and Pennsylvania regulate our
district steam energy business. Pennsylvania requires us to seek State
regulatory approval of our prices for steam service. Missouri requires us to
seek State regulatory approval of our prices for steam service from our Kansas
City facilities. Our other businesses are not subject to State utility price
regulation. In 1999, Maryland and New Jersey removed the requirement to seek
State regulatory approval of pricing for steam.

         ELECTRICITY. We produce electricity at seventeen of our plants. The
electricity produced is sold to the local utility company or used by our
customers or us. Our electric generating plants, which sell their power to the
local utility, are located in Kansas City, MO, London, Ontario (Canada), Nassau
County, NY, Philadelphia, PA and Trenton, NJ. The plants in Nassau County, NY,
Philadelphia, PA, Trenton, NJ and Kansas City, MO are qualified for an exemption
from regulation under the Public Utility Regulatory Policies Act of 1978.

         CHILLED WATER. At fifteen of our facilities, we produce chilled water,
which we provide to customers to cool commercial building space and for process
chilling.

         OTHER ENERGY SERVICES. We provide other utility services to our
customers such as compressed air and water treatment. We also provide operating
supervision, management and maintenance of facilities as well as advice and
assistance regarding initial design, construction and start-up, with respect to
energy use as well as energy audits.

FUEL AND RAW MATERIALS

         We are a significant purchaser of gas, coal, oil and biomass fuels, as
well as chillers, boilers, generators and other equipment used for heating,
cooling and electric generation. Most of our gas, coal, oil and biomass fuel
requirements, as well as most of our other supplies, are purchased from local
suppliers. We believe that we have adequate sources of fuel, supplies and
equipment.

COMPETITION

PROVISION OF DISTRICT HEATING, ELECTRICITY AND COOLING

         The sale of electricity at wholesale over the interstate electric power
grid is highly competitive. Where permitted by State law, the sale of electric
power to individual end-users is also highly competitive. Some States continue
to ban retail sales of electric power by non-utility companies as a means to
protect the local electric utility monopoly. Other States permit non-utility
generators to sell their electric power to only one user on the same site as
their power plant. The provision of heating and cooling services through a
multiple-user distribution system is highly competitive with on-site generation
of the heat and cooling. There are currently very few competing operators of
multiple-user district energy systems. Our principal thermal energy competition
is from potential customers who own and operate their own boiler and chilled
water plants. These customers are often provided financial incentives to install
and retain their own plants by the suppliers of raw energy (such as local oil,
natural gas and electricity companies) and by equipment suppliers that sell
products and services to users who self-generate thermal energy. In several
locations, local utilities are competing directly with us through unregulated
subsidiaries offering steam and/or cooling.

         We believe that competition in the district energy business turns on
the customers' evaluation of expected cost savings and reliability of service.
We compete to attract and retain customers, and also compete for contracts and
other awards to develop new facilities and systems. A significant additional
factor is the high capital cost involved in constructing a district energy
system. While this factor provides a competitive advantage once we are operating
a completed system, high initial capital costs typically require us to have a
significant number of customers, preferably under long-term contracts, prior to
undertaking construction of a new cooling or heating system. We will pursue
opportunities to expand our district energy systems and services wherever our
expertise provides a competitive advantage.

TECHNOLOGY

         Our research and development efforts have focused on improving the
value of the energy products we extract and deliver. Our principal focus has
been on finding ways to more efficiently convert fuel to energy and on improved
generating, monitoring, automation and storage technologies. These efforts have
resulted in the trigeneration machine, innovations in chilled water storage and
control systems, innovative applications of standard modular equipment, and
various incremental operational improvements. Expenditures for
customer-sponsored or Company-sponsored research and development are not
separately reflected in our financial statements, and the Company believes that
if such expenditures were so allocated, the amounts would not be material. We
have been granted patents for the trigeneration


                                       5
<PAGE>

machine, our freeze suppression chemical for stratified cold water storage and a
fuel blending system for emissions control. None of these patents are believed
to be material.

YEAR 2000 COMPUTER ISSUES

         We discuss our Year 2000 computer processing compliance status in Item
7 of this Annual Report ("Management's Discussion and Analysis of Financial
Condition and Results of Operations").

ENVIRONMENTAL

         Our operations are subject to extensive federal, state, provincial and
local environmental laws and regulations that govern, among other matters,
emissions into the air, the discharge of effluents, the use of water, fuel tank
management and the storage, handling and disposal of toxic waste material. We
believe that our facilities are in substantial compliance with applicable
environmental laws and regulations and seek to maintain such compliance through
appropriate management policies and procedures.

         We invest substantial funds to modify facilities to comply with
applicable environmental laws and plan additional capital expenditures for these
purposes in the future. We spent approximately $ 2.9 million and $ 3.9 million
in 1999 and 1998, respectively, to comply with these requirements and estimate
that the expenditures for environmental compliance in 2000 through 2002 will be
approximately $ 11.2 million in the aggregate. These expenditures may include
improvements at certain facilities for air emission control and monitoring
equipment, wastewater discharge control equipment, asbestos control and other
applicable environmental requirements. Additional amounts to be spent for
environmental compliance in future years will depend on new laws and regulations
and other changes in environmental concerns and legal requirements.

         Our United States facilities are subject to regulation by the U. S.
Environmental Protection Agency under the Clean Air Act, among other laws. In
May of 2003, regulations under the Clean Air Act are scheduled to create an
allocation and trading program with respect to the release of nitrogen oxides
into the atmosphere from facilities located in 12 States in the northeast United
States. We produce nitrogen oxides at substantially all of our facilities. Our
facilities in Philadelphia, PA and Nassau County, NY are currently expected to
be required to comply with a nitrogen oxides emissions budget. Based on the
current emissions budget allocated by the EPA to our facilities in Philadelphia,
PA and Nassau County, NY, we do not believe that our compliance with these
requirements will have a material impact on our results of operations. If the
EPA revises our current budget, that may have a material impact on our results
of operations. Our other facilities may become subject to nitrogen oxide
emissions reductions requirements in the future. We are not able to predict what
the impact of any new requirements would be at this time.

EMPLOYEES

         As of December 31, 1999, we had approximately 846 employees of which
110 were covered by union agreements.

ITEM 2.  PROPERTIES

         We operate 51 energy plants at 36 different locations. We own all or a
portion of the interests in most of our facilities, lease some facilities and
manage others. Note 13 of the Notes to Consolidated Financial Statements of the
Company (included later in this Annual Report) describes how our assets are
pledged as security under our financing agreements.

         We operate district energy systems in Boston, MA, Baltimore, MD,
Charlottetown, Prince Edward Island (Canada), Kansas City, MO, London, Ontario
(Canada), Oklahoma City, OK, Orlando, FL, Philadelphia, PA, St. Louis, MO,
Trenton, NJ and Tulsa, OK. In Philadelphia, PA, we have a one half interest in
the Grays Ferry Cogeneration Facility. We operate energy systems on the site of
our industrial and commercial customers in Nassau County, NY, Chicago, IL,
Golden, CO, Eden NC, Forest City, NC, Greenville, MS, Lenoir, NC, Loudon, TN,
Marion, NC, Tuscola, IL, Boca Raton, FL, Baltimore, MD, Decatur, AL, Champaign,
IL, Ashtabula, OH, College Park, MD, Rochester, NY and Syracuse, NY. Certain of
these facilities are subject to minority interests due to investments by our
Trigen-Cinergy joint venture, among other factors.

         The Company leases approximately 22,000 square feet in White Plains,
New York, which houses our executive offices, financial, engineering, marketing,
legal and data processing staffs. The term of the lease extends through March
31, 2005 and the annual rent due thereunder is approximately $.5 million. We
believe that these facilities are adequate to meet our needs for the foreseeable
future, and that suitable replacement space is readily available.

ITEM 3.  LEGAL PROCEEDINGS

OKLAHOMA LITIGATION

         In September 1996, our subsidiary, Trigen-Oklahoma City Energy
Corporation ("Trigen-Oklahoma City"), commenced an antitrust action in Federal
District Court in Oklahoma City seeking injunctions and actual, treble and
punitive damages from a local utility, Oklahoma Gas and Electric Company
("OG&E"), based on alleged anti-competitive actions against Trigen-Oklahoma City
Energy Corporation by OG&E. Trigen-Oklahoma City's antitrust action went to
trial in 1998 and on December 21, 1998, the jury returned a verdict in favor of
Trigen. On January 19, 1999, the Court entered a judgment in favor of Trigen in
the amount of $27.8 million. On January 25, 2000 the court decided post-trial
motions to vacate or modify the judgment reducing the judgment to $20.6 million.
OG&E has filed an appeal to the Tenth Circuit Court of Appeals and has posted a
bond in order to stay enforcement of the judgment pending appeal. Trigen has
filed a cross-appeal. Trigen's separate motion for attorney's fees (seeking
approximately $3 million) is pending but OG&E has requested that the court
postpone a hearing on that motion until the appeals are decided by the Circuit
Court. We have not recognized any gain with respect to this matter because we
cannot predict the final outcome.

KINETIC ENERGY LITIGATION

         On May 2, 1997, a judgment was entered against us in the amount of $4.3
million following a jury trial in a law suit by Kinetic Energy Development
Corporation against Trigen in the Circuit Court of Jackson County, Missouri, in
connection with our acquisition of the Kansas City steam system. Kinetic claimed
for compensation alleged to be owed to it by Trigen in connection with that
acquisition. On August 6, 1997, the Court set aside the jury verdict and granted
judgment for Trigen. Kinetic Energy Development Corporation appealed that order
and on December 8, 1998, the Missouri Court of Appeals set aside the lower court
decision and ordered a new trial. On December 22, 1998, we filed a motion for
rehearing with the Missouri Court of Appeals and/or a review by the Missouri
Supreme Court. The Court of Appeals granted our motion for rehearing. On
September 7, 1999, the Court of Appeals held that Kinetic had proven only
nominal damages at trial and returned the case to Circuit Court for retrial. The
retrial will allow Kinetic to attempt to establish that it is entitled to some
award for the reasonable value of its services, if any, in connection with the
Trigen acquisition of the Kansas City steam system. The case presently awaits
rescheduling for trial. We believe we have good defenses to these claims.
Accordingly, we have not recognized any loss or expense (other than defense
costs) with respect to this matter, although we cannot predict the final
outcome.

GRAYS FERRY LITIGATION

         On April 23, 1999, the Pennsylvania Court of Common Pleas of
Philadelphia County approved a settlement agreement which ended the lawsuit
brought by Grays Ferry Cogeneration Partnership (the "Partnership"),
Trigen-Schuylkill Cogeneration, Inc. and CogenAmerica Schuylkill Inc. against
PECO Energy Company and Adwin (Schuylkill) Cogeneration, Inc. The Partnership is
the owner of the Grays Ferry Cogeneration Facility located in Philadelphia,
Pennsylvania. The Partnership, Trigen-Schuylkill and CogenAmerica commenced this
lawsuit in reaction to the alleged


                                       7
<PAGE>

termination by PECO on March 3, 1998, of the electric power purchase agreements
between the Partnership and PECO (the "Power Purchase Agreements").

         Prior to the settlement, we owned a one-third interest in the
Partnership through our wholly owned subsidiary, Trigen-Schuylkill. CogenAmerica
and Adwin owned the other two-thirds interests in the Partnership. Adwin is an
indirect wholly owned subsidiary of PECO. Under the settlement agreement, PECO's
subsidiary, Adwin, surrendered its rights to its one-third partnership interest
in the Partnership to the two remaining partners, Trigen-Schuylkill and
CogenAmerica. As a result, we own one half of the Partnership and CogenAmerica
owns the other half.

         In the year 2001, the energy price under the Power Purchase Agreements
will be based upon a percentage of a market based index, which we expect to
produce substantially lower revenues from sales to PECO than the more favorable
rates of the early contract years. Under the settlement agreement the
Partnership gained the right to sell to third parties electric energy and
capacity from the facility in excess of the 150 megawatts which PECO is required
to purchase under the Power Purchase Agreements, subject to a right of first
refusal for PECO. We expect that the ability to sell to third parties electric
energy and capacity above the 150 megawatts under contract to PECO, will result
in an opportunity to improve the financial performance of the Partnership. The
Partnership will now have the ability to institute capital modifications to the
combustion turbine to increase electric capacity during the summer months when
the price of electric capacity and energy are historically the highest.

         Separately, The Chase Manhattan Bank, as agent for several commercial
banks (collectively "Chase"), and Westinghouse Power Generation, which
collectively financed the construction of the Gray's Ferry Cogeneration
Facility, agreed to dismiss their lawsuits against PECO. Chase and Westinghouse
also agreed that they will not charge the Partnership for any default interest
up to April 16, 1999, although they have reserved the right to do so with
respect to periods after April 16, 1999.

         The Partnership is in default under its separate credit agreements with
Westinghouse and Chase for the following reasons. The Partnership did not
convert on time its short-term construction loan from Chase to a longer term
loan. The Partnership could not complete that conversion because of a dispute
with the construction contractor, which has now been resolved. The Partnership
also did not make principal payments to Westinghouse because the Chase loan
agreement prohibits such payments to subordinate parties while the Partnership
is in default. Westinghouse is a subordinate party.

         The Partnership owes a total principal amount of approximately $79.4
million to Chase. Chase has not accelerated the debt owing under the Credit
Agreement. Chase has required to date, and may require in the future, the
Partnership to apply available cash held by Partnership (net of operating
expenses) toward repayment of the principal amount of the loans outstanding to
Chase. The Partnership owes a total principal amount of approximately $15
million to Westinghouse. On March 1, 2000, Westinghouse demanded full payment of
the amount owing to Westinghouse under its credit agreement. Only the
Partnership assets and the Partners' ownership interests in the Partnership
secure the Partnership's debt under the Chase and Westinghouse loans. The
Partnership has accrued $3.0 million in default interest since April 16, 1999.

         To resolve these matters we have negotiated an amendment to the credit
agreement with Chase and we are negotiating with Westinghouse and other
subordinate parties.

NASSAU LITIGATION

         On May 29, 1998, the County of Nassau, New York commenced an action
against Trigen Energy Corporation and Trigen-Nassau Energy Corporation in New
York State Supreme Court. Trigen-Nassau provides energy services to Nassau
County under various agreements. Nassau County alleges that Trigen-Nassau
breached those agreements by, among other means, charging the County for certain
real estate taxes that the County contends are Trigen-Nassau's responsibility.
On October 8, 1998, the Court dismissed the claims against Trigen Energy
Corporation. On November 9, 1998, Trigen-Nassau filed counterclaims against
Nassau County, seeking $1.6 million in damages. Trigen-Nassau alleges that
Nassau County breached the parties' agreements by, among other things, failing
to operate and maintain certain facilities and equipment. On January 21, 1999,
the County requested that the Court dismiss Trigen-Nassau's counterclaims. On
April 5, 1999, the Court dismissed some but not all of Trigen-Nassau's
counterclaims. The Court declined to dismiss Trigen-Nassau's counterclaims that
seek approximately $1.5 million in damages. The County is seeking approximately
$10 million in damages. We believe we have good defenses to the County's claims.
Accordingly, we have not recognized any loss or expense (other than defense
costs) with respect to this matter, although we cannot predict the final
outcome.

ESI LITIGATION

         In 1996, ESI, Inc. commenced an action against, among others, Coastal
Power Company, Latin American Energy Development, Inc. and La Casa Castro S.A.
de N.V. in the United States District Court for the Southern District of New
York. On September 17, 1998, ESI, Inc. amended its complaint naming Trigen as an
additional defendant. This action arises out of the development by Trigen, Latin
American Energy, La Casa Castro and others, of an independent power project in
El Salvador between 1993 and 1994. Trigen transferred its interest in the
project to Tenneco Gas International in May 1994. In July 1994, Tenneco
transferred its interest in the project to Coastal Power Company, which
currently owns and operates the project. ESI claimed that it was entitled to a
2.5% interest in the project and that Coastal had wrongfully withheld or denied
ESI's interest. ESI further claimed that Trigen had failed to disclose ESI's
interest to Tenneco and so was responsible, in whole or in part, for ESI's
failure to receive a 2.5% interest in the project from Coastal.

         On October 8, 1998, Latin American Energy asserted cross-claims against
Trigen, Coastal and Tenneco claiming that it too had been denied its carried
interest in the Project. On October 28, 1998, La Casa Castro asserted
cross-claims against Trigen and on November 6, 1998, Coastal asserted
cross-claims against Trigen for indemnification, each alleged that Trigen failed
to disclose ESI's claimed interest to Tenneco and that Trigen was responsible
for any damages that each may be required to pay to ESI and Latin American.

         On December 15, 1998, Trigen filed an amended answer denying liability
for these claims and cross-claimed against Latin American Energy, Tenneco,
Coastal and La Casa Castro, asserting that these parties were responsible for
any damages owed to ESI and Latin American. On December 23, 1998, ESI and Latin
American dismissed without prejudice their claims against Trigen.

         Coastal and La Casa Castro are continuing to assert their claims
against Trigen for any damages they may be required to pay to ESI or Latin
American. At this time, the case is in the early stages of discovery and as such
we are not able to estimate the amount of damages that ESI and Latin American
are seeking. We believe we have good defenses to Coastal's claims and La Casa
Castro's claims. Accordingly, we have not recognized any loss of expense (other
than defense costs) with respect to this matter, although we cannot predict the
final outcome.

SHAREHOLDER CLASS ACTIONS AGAINST TRIGEN

COMPLAINTS OF FOTHERGILL, CORTEZ, AND BERKOWITZ.

         On September 23, 1999, three complaints were filed in the Court of
Chancery of the State of Delaware against: Trigen Energy Corporation, Suez
Lyonnaise Des Eaux SA, Patrick Buffet, George F. Keane, Thomas R. Casten,
Philippe Brongniart, Olivier Degos, Patrick Desnos, Richard E. Kessel, Charles
E. Bayless, Michel Bleitrach, Dominique Mangin D'Ouince and Michel Cassou. The
individual defendants were sued in their capacity as Trigen directors and/or
former Trigen directors. The complaints were filed, respectively, by Michael
Fothergill, Rosa Cortez and Sarah Berkowitz. Each complaint was filed
purportedly as a class action on behalf of the Company's shareholders. The
complaints raised substantially identical allegations: that Trigen received a
proposal from Suez to take Trigen private for $22.00 per share in cash. The
plaintiffs alleged that this price does not represent the true value of Trigen
and is unfair to the minority shareholders. Plaintiffs further alleged that
because Suez owns approximately 52% of Trigen's outstanding shares, Suez has the
power to effectuate the transaction without regard to the minority shareholders.
Plaintiffs sought class certification, declaratory and injunctive relief (or
money damages if the transaction is consummated), and an accounting. By
agreement of the parties, an order has been entered consolidating all three
actions under the Fothergill caption.

         On February 22, 2000, counsel for ELYO and the plaintiffs reached an
agreement to settle this lawsuit, subject to court approval. The settlement does
not require any payment to the plaintiffs from the Company or its directors.
Accordingly, we have not recognized any loss or expense (other than defense
costs and certain costs of providing Notice of Settlement to Class members) with
respect to this matter, although we cannot predict the final outcome. The
parties are in the process of submitting this settlement to the Court of
Chancery of the State of Delaware for approval.

COMPLAINT OF RICE.

         On March 16, 2000, Adam Rice filed a complaint in the Supreme Court of
the State of New York, County of Westchester against Trigen Energy Corporation,
Suez Lyonnaise Des Eaux S.A., Elyo, S.A., T Acquisition Corporation, Christine
Morin-Postel, Richard E. Kessel, George Keane, Patrick Buffet, Olivier Degos,
Philippe Brongniart, Michel Bleitrach, Dominique Mangin D'Ouince and Charles
Bayless. The complaint was filed purportedly as a class action on behalf of the
Company's shareholders. The individual defendants were sued in their capacity as
Trigen directors. The plaintiff alleged that the defendants have breached their
fiduciary duties to plaintiff and our public shareholders by not renegotiating
and/or reformulating the terms of the tender offer by which T Acquisition
Corporation has offered to purchase all of our outstanding shares at a price of
$23.50 per share. Plaintiff seeks class certification and money damages as well
as other unspecified relief. We believe we have good defenses to these claims.
Accordingly, we have not recognized any loss or expense (other than defense
costs) with respect tot his matter, although we cannot predict the final
outcome.

OTHER LITIGATION

         We are subject from time to time to various other claims that arise in
the normal course of business, and we believe that the outcome of these matters
(either individually or in the aggregate) will not have a material adverse
effect on our business results of operation or financial condition.

</TABLE>

         Our preferred rate structure for thermal energy includes fixed and
variable components. These rate structures are intended to cause revenues to
match our costs of providing capacity, including projected debt service and
return on equity, thermal losses in the distribution network, taxes, labor and
scheduled maintenance and repair. The capacity component, which is independent
of usage in the period, generally includes cost escalation provisions. These
rate structures also contain a charge, which varies with usage during the
period, and which is intended to cover directly variable costs, so as to pass
through to customers our cost of fuel.

         A significant portion of our revenues and operating profit are subject
to seasonal fluctuation due to peak heating demand in the winter and peak
cooling demand in the summer. This seasonal fluctuation is accentuated in those
acquired steam systems where our preferred rate structures are not employed. Our
strategy of converting old contracts to our preferred rate structures, adding
cooling, electricity, energy services and industrial process loads has reduced
the concentration of revenues in cold months during 1999 and is expected to
continue in the future.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1999 COMPARED WITH YEAR ENDED DECEMBER 31, 1998

OVERVIEW

         For the year ended December 31, 1999, earnings before a cumulative
effect of a change in accounting principle amounted to $16.1 million, or $1.33
per diluted earnings per share. This compared to $6.6 million, or $.55 per
diluted earnings per share before extraordinary item reported in 1998. For the
year ended December 31, 1999, net earnings amounted to $11.2 million, or $.92
per diluted earnings per share after the effect of the adoption of a change in
accounting principle. Revenues of $280.4 million for 1999 increased $38.0
million, or 15.7% over 1998. Operating income was $39.6 million and the
operating margin was 14.1% in 1999 compared with operating income of $31.8
million and an operating


                                       13
<PAGE>

margin of 13.1% in 1998. Included in net earnings for 1999 was a non-recurring
after-tax gain of $8.5 million, or $.70 per diluted share, related to the PECO
lawsuit settlement. (See Note 23 of Notes to Consolidated Financial Statements,
Legal Proceedings)

REVENUES

         Revenues of $280.4 million in 1999 increased $38.0 million from
revenues of $242.4 million in 1998. Thermal energy revenue increased $30.1
million to $212.5 million. Units of thermal energy sold increased 19% over 1998
reflecting a somewhat colder winter and the full year contribution of our joint
venture in Tuscola, Illinois.

         Electric energy revenues increased $2.5 million to $45.2 million in
1999. The predominant reason for this increase is due to our Nassau facility,
which operated for the full year in 1999, but was taken off line in 1998 for 22
days for a scheduled five year major overhaul. In addition, our new cogeneration
plant in St. Louis began operations and contributed to electricity revenues in
1999.

         Equity in earnings (losses) of non-consolidated subsidiaries increased
$2.9 million in 1999. This is due essentially to the improvement in earnings of
the Grays Ferry Cogeneration Partnership and the increase in our ownership share
to 50% from 33 1/3% as a result of the PECO settlement. The increase in the
Partnership income reflects the reversal of 1998 default interest of $1.8
million (our share is $.9 million) which was waived through April 16, 1999 after
such settlement (See Note 23 of the Notes to Consolidated Financial Statements,
Legal Proceedings).

         Fees earned and other revenues increased by $2.5 million in 1999 as a
result of our new joint venture projects in Baltimore, MD and Ashtabula, OH.

OPERATING EXPENSES

         Fuel and consumables in 1999 increased $15.8 million to $117.3 million,
an increase of 15.6%. This increase reflects the increased level of energy
sales. Our rates typically enable us to pass changes in fuel and most commodity
costs to the customer. As a result, such changes have little impact on operating
income.

         Production and operating costs are those costs incurred to operate the
plants, other than fuel and consumables in 1999, and include labor and
supervisory personnel, repair and maintenance costs, and plant operating costs.
In 1999, production and operating costs totaled $55.0 million, a 13.9% increase
over 1998. This increase is primarily due to the inclusion of production and
operating costs associated with 1999 new industrial accounts.

         Depreciation and amortization expense was $27.8 million in 1999,
compared with $24.4 million in 1998. In 1999, we recognized an asset impairment
loss of $3.0 million. This loss represents the difference between the carrying
value of the long-lived assets of a division of our Canadian subsidiary and the
fair value of those assets based on estimated discounted future cash flows. The
loss is included in depreciation expense.

         General and administrative expenses of $40.8 million in 1999 increased
$4.4 million compared to 1998. Expenses in 1998 included special cost
adjustments of $2.0 million for insurance and employee related costs. Increased
costs in 1999 are primarily due to legal expenses incurred in pursuing the
Oklahoma City antitrust lawsuit against OG&E, overhead related to new industrial
accounts and to increased expenses required to pursue energy outsourcing
opportunities.

OTHER INCOME/(EXPENSE)

         Interest expense increased $2.3 million to $26.0 million in 1999
primarily due to higher debt levels required to finance new business.

         Other income, net was $17.4 million in 1999, an increase of $11.8
million over 1998. This is primarily due to recognizing the gain from our share
of the Adwin interest in the Grays Ferry Cogeneration Partnership which was
surrendered to us on April 23, 1999 as part of the PECO settlement (See Note 23
of Notes to Consolidated Financial Statements - Legal Proceedings). We recorded
a pre-tax gain of $14.5 million which represents the market value of the share
of Adwin's interest in the Partnership that was surrendered to us. Other income,
net for 1998 included the net results from gains of $2.1 million from the sale
of nitrogen oxide emission allowances and $1.7 million from an insurance
settlement.


                                       14
<PAGE>

INCOME TAXES

         Our effective tax rate is determined primarily by the federal statutory
rate of 35% and state and local income taxes. The effective tax rate was 41.4%
in 1999 and 41.1% in 1998.

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

OVERVIEW

         For the year ended December 31, 1998, net earnings were $6.3 million
compared with $5.0 million in 1997, and diluted earnings per common share were
$.52 in 1998 compared with $.41 per common share 1997. Included in net earnings
for 1998 was an extraordinary loss of $.3 million, or $.03 per common share, as
a result of the early extinguishment of debt. Revenues of $242.4 million in 1998
increased $1.7 million over revenues of $240.7 million in 1997. Operating income
was $31.8 million in 1998 and the operating margin was 13.1% in 1998 compared
with operating income of $28.7 million and an operating margin of 11.9% in 1997.
Offsetting the continuing mild weather and unfavorable results from our Canadian
operations were positive contributions from the Trigen-BioPower acquisition and
the Grays Ferry Cogeneration Partnership. Both were major contributors to the
higher levels of revenues and profits in 1998.

REVENUES

         Revenues of $242.4 million in 1998 increased $1.7 million from $240.7
million in 1997. Thermal energy revenue increased $2.9 million to $182.4
million. Units of thermal energy sold increased 19% over 1997 primarily
reflecting the contribution of Trigen-BioPower, which was acquired in January
1998. Partially offsetting this increase were lower thermal energy sales in
Philadelphia, Boston and Baltimore due to the effect of milder weather patterns.

         Electric energy revenues decreased $6.3 million to $42.7 million in
1998. The Nassau plant was taken off-line by the local utility, as permitted
under their contract, for a longer period of time in 1998 than in 1997. In
addition, in 1998, this facility was taken off-line for twenty-two days for a
scheduled five year major overhaul. The Grays Ferry Cogeneration Partnership, of
which we were a 33% partner, commenced operations in January 1998 and produced
$60.3 million in electrical revenues for the year. Grays Ferry replaced our
electric generation in Philadelphia and thus lowered reported revenues from
electricity compared to the prior year by approximately $3.2 million. Our 33%
share of the Grays Ferry Cogeneration Partnership's electric revenues are $20.1
million and the resulting profits are reflected in equity earnings of
non-consolidated subsidiaries.

         Equity earnings/(losses) of non-consolidated subsidiaries in 1998
exceeded 1997 by $5.9 million, primarily reflecting our share of earnings from
the Grays Ferry Cogeneration Partnership.

         Fees earned and other revenues declined slightly in 1998, reflecting
the absence of revenues associated with the sale of a natural gas pipeline in
1997. This was essentially offset by the inclusion of fees from the Grays Ferry
Cogeneration Partnership in 1998.

OPERATING EXPENSES

         Fuel and consumables were $101.5 million in 1998, a $12.7 million
decrease from 1997, in spite of a significant increase of 19% in thermal energy
units sold. This decrease reflects the lower level of energy sales due to warm
weather at systems primarily located in the Northeast and lower fuel prices at
our fossil fuel plants. Our rate structure typically enables us to pass changes
in fuel and most commodity costs to the customer. As a result, such changes have
little impact on operating income. Fuel and consumables' costs decreased from
47.4% of revenues in 1997 to 41.9% in 1998 largely due to the addition of seven
biomass fueled plants with relatively low fuel prices.

         Production and operating costs are those costs incurred to operate the
plants, other than fuel and consumables, and include labor and supervisory
personnel, repair and maintenance costs, and plant operating costs. In 1998,
production and operating costs totaled $48.3 million, a 2.5% increase over 1997.
This increase is primarily due to the inclusion of production and operating
costs associated with Trigen-BioPower, which was acquired in January 1998.


                                       15
<PAGE>

         Depreciation and amortization expense was $24.4 million in 1998,
compared with $18.2 million in 1997. The increase is primarily attributable to
the addition of Trigen-BioPower depreciation expense in 1998.

         General and administrative expenses increased $4.0 million to $36.4
million in 1998, a 12.3% increase over 1997. Contributing to the increase was
the inclusion of 1998 Trigen-BioPower general and administrative expenses and a
$2.0 million increase in insurance and employee-related costs, and the costs of
pursuing the Oklahoma City antitrust lawsuit against OG&E. All of the 1998 costs
of the lawsuit were expensed in 1998, and a gain, if any, will not be recognized
until a final judgment is affirmed on appeal or a final settlement is
consummated.

OTHER INCOME/(EXPENSE)

         Interest expense increased $4.8 million to $23.7 million in 1998
primarily due to financing the Trigen-BioPower acquisition and the purchase of
an additional 48% interest in the Trigen-Nations Energy Company Limited
Partnership.

         Other income, net was $5.6 million in 1998, an increase of $3.1 million
over 1997. The increase primarily results from gains during 1998 of $2.1 million
from the sale of nitrogen oxide emission allowances and $1.7 million from an
insurance settlement.

INCOME TAXES

         Our effective tax rate is determined primarily by the federal statutory
rate of 35% and state and local income taxes. The effective tax rate was 41.1%
in 1998 and 41.0% in 1997.

LIQUIDITY AND FINANCIAL POSITION

         We ended 1999 with total debt of $441.2 million compared with $375.1
million at year-end 1998. Stockholders' equity increased to $160.0 million in
1999 from $147.9 million in 1998. Our working capital deficit was $14.6 million
at year end 1999 compared with a working capital deficit of $9.5 million at
year-end 1998. At December 31, 1999 and 1998, cash and cash equivalents were
$20.0 million and $14.7 million, respectively, of which $13.6 million and $13.3
million, respectively, was restricted as to use. See Note 7 of the Notes to
Consolidated Financial Statements for information on the restrictions.

         Our principal sources of funds are proceeds from new borrowings and
cash from operations. In 1999, $38.6 million was generated from operating
activities compared with $36.4 million in 1998 and $23.3 million in 1997. During
1999 we invested $93.6 million in capital expenditures, $5.8 million for the
acquisition of energy facilities, and paid dividends of $1.7 million to
shareholders. These expenditures were financed by cash generated from operating
activities and by $65.1 million of net new borrowings.

         On April 4, 1997, we entered into a $160.0 million revolving credit
agreement with several banks. This facility was used to repay indebtedness
outstanding under a $62.5 million credit facility entered into in 1995. The
$160.0 million facility is for an initial period of three years and may be
extended by a total of two one-year periods. Borrowings under the facility bear
interest, at our option, at an annual rate equal to the base rate or the LIBOR
rate plus 3/4%. The base rate is the higher of the prime lending rate or the
Federal Reserve reported Federal funds rate plus 1/2%. On June 10, 1997, we
amended the $160.0 million credit agreement by reducing the facility to $125.0
million and entered into a $35.0 million revolving credit facility with the same
group of banks. The new facility is for an initial 364-day period and may be
extended annually at the option of the banks. The terms and conditions of both
facilities are the same. On September 23, 1998, the $125.0 million three year
facility was increased by $35.75 million and the initial period was increased by
one year. The base rate is the higher of the prime lending rate or the Federal
Reserve reported Federal funds rate. The average effective rate on the facility
was 6.0% in 1999 and the rate at December 31, 1999 was 7.2%. On December 30,
1998, we borrowed from an affiliate, Cofreth American Corporation, $50.0 million
for acquisitions and project development. The $50.0 million was initially used
to partially pay down the corporate facility. The $50.0 million is subordinate
and junior in right of payment to all other debt. The subordinated debt may be
redeemed in whole or in part at the option of Cofreth American Corporation with
the net proceeds of an equity sale by the Company. The debt matures on December
31, 2010 and the interest rate is 7.38%.

         At December 31, 1999, we had $2.8 million of borrowings available under
our credit facilities for working capital and general corporate purposes. Our
loan agreements contain various restrictions and conditions with which we are in
compliance (See Note 23 for default information related to Grays Ferry
Cogeneration Partnership). Certain loan


                                       16
<PAGE>

agreements restrict payments by subsidiaries to the Company, unless the payments
are for specified purposes or the subsidiary meets certain covenants. Management
believes that cash generated from operations, borrowings available under our
credit facilities, the ability to obtain financing from our affiliates, and
access to capital markets provide adequate resources to meet ongoing operating
needs and future capital expenditures related to the existing business and
development of new projects. See Note 13 of the Notes to Consolidated Financial
Statements for information on long-term debt.

         During 1999, stockholders' equity increased $12.1 million to $160.0
million. This increase reflects $11.2 million of net earnings, $1.5 million from
the issuance of common stock, $.5 million of amortization of unearned
compensation related to restricted shares and a $.8 million cumulative
translation adjustment, partially offset by $1.7 million of dividend payments to
shareholders and the purchase of 14,000 shares of common stock for the treasury
at a cost of $.2 million.

CAPITAL EXPENDITURES

         Capital expenditures were $93.6 million in 1999 compared with $42.9
million in 1998 and $39.4 million in 1997, as we continue to invest in capital
improvements to increase efficiency, reduce costs, pursue new opportunities,
expand production and improve facilities. Capital expenditures during 1999
included construction of facilities in St. Louis, MO, Baltimore, MD, Ashtabula,
OH, College Park, MD, Decatur, AL, Tampico, Mexico and St. Mary's, GA.

ENVIRONMENTAL EXPENDITURES

         Our facilities are subject to governmental requirements with respect to
the discharge of materials and otherwise relating to protection of the
environment. We spent approximately $2.9 million and $3.9 million in 1999 and
1998, respectively, to comply with these requirements and estimate that our
expenditures for environmental compliance in 2000 through 2002 will be
approximately $11.2 million in the aggregate. These expenditures include
improvements at certain facilities for air emission control equipment as
required by the United States Clean Air Act (the "Clean Air Act"), wastewater
discharge control equipment, asbestos control and replacement of CFC
refrigerants.

ACQUISITIONS

         On January 22, 1998, we acquired all of the capital stock of Power
Sources, Inc. (renamed Trigen-BioPower, Inc.), a biomass-to-energy power plant
developer and operator, for a cash price of $44.1 million. On September 23,
1998, we purchased an additional 48% interest in Trigen-Nations Energy Company
Limited Partnership from Nations Energy Corporation for $21.3 million. On June
22, 1999, we purchased the final 1% of the limited partnership for $.3 million.
The acquisitions were funded from our existing credit facilities. See Note 6 of
the Notes to Consolidated Financial Statements for information on the
acquisition.

IMPACT OF NEW ACCOUNTING STANDARDS

         In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities" ("SOP 98-5"). SOP 98-5 requires costs of start-up activities and
organizational costs to be expensed as incurred. SOP 98-5 is effective for
financial statements for fiscal years beginning after December 15, 1998. We
adopted SOP 98-5 effective January 1, 1999. The effect of the adoption was an
after-tax charge of $4.9 million which was reported as a cumulative effect of a
change in an accounting principle.

         Based on preliminary analyses, we do not expect that the future
adoption of Statement of Financial Accounting Standards No. 133, "Accounting for
Derivative Instruments and Hedging Activities," ("SFAS No. 133") will have a
material effect on the Company's results of operations or financial condition.
We will adopt SFAS No. 133 effective January 1, 2001.

YEAR 2000 DATE CONVERSION

         We experienced no material problems with our information systems or
with our customers or suppliers with which we deal, as a result of the date
change to the year 2000. We spent approximately $1.0 million for the years 1997
through 1999 to make the required modifications to our systems. There was no
material effect on our results of operations as a result of the Year 2000 issue.
No significant information technology projects or capital spending were deferred
as a result of our Year 2000 program.

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

         We do not engage in the trading of market risk sensitive instruments
in the normal course of business. Our short and long-term debt is subject to
fixed and variable interest rates including rates primarily based on LIBOR.
An analysis of debt is found in Notes 12 and 13 of the Notes to Consolidated
Financial Statements, Short-Term Debt and Long-Term Debt, included in this
Annual Report. Based upon the debt balances at December 31, 1999, a change in
the LIBOR rate of .25% would have a corresponding change in interest expense
of approximately $.8 million per year when three-month LIBOR is under 6.0%
ranging to approximately $.7 million per year when three-month LIBOR is over
7.5%. Three-month LIBOR at December 31, 1999 was 6.00125%.

         We use financial instruments to limit the financial risk of increases
in interest rates on our floating rate debt. The differential to be paid or
received under financial instruments is accrued and recognized in interest
expense as interest rates change. As of December 31, 1999, we had outstanding
interest rate swap, cap and collar agreements related to $39.4 million of debt
outstanding, with an average fixed interest rate of 6.2% and an average
remaining life of 5 years. The fair value of the swap, cap and collar was a
receivable of $1.5 million at December 31, 1999. We do not expect these
financial instruments to have a material effect on our earnings or cash flows or
on the fair value of these instruments.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

         The financial statements and financial statement schedules that are
filed as part of this Annual Report begin on page F-1 hereof.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
        FINANCIAL DISCLOSURE

         Our principal accountant for the fiscal years ending December 31, 1994,
December 31, 1995, December 31, 1996 and December 31, 1997 was KPMG Peat Marwick
LLP ("KPMG"). In 1998, we made a decision to change our principal accountant for
our fiscal year ending December 31, 1998, for the reason set forth below. In
1998, the Audit Committee and the Board of Directors of the Company approved
this determination.

         KPMG is also in the business of providing consulting services to
clients with respect to issues related to the energy business. In 1997, a
dispute arose between the Company and the consulting services division of KPMG
with respect to the conduct of consulting services provided to a third party.
That dispute was not resolved to our satisfaction. The change in principal
accountant was not due to any matter regarding KPMG's accounting services.
KPMG's report on our financial statements for 1996 and 1997 did not contain an
adverse opinion or a disclaimer of opinion, nor was it qualified or modified as
to uncertainty, audit scope or accounting principles. Neither were there, during
the 1996 and 1997 fiscal years or the period since December 31, 1997, any
disagreement with KPMG on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure, which
disagreement, if not resolved to the satisfaction of KPMG, would have caused it
to make reference to the subject matter of the disagreement in connection with
its report.

         In 1998, the Board of Directors selected Arthur Andersen LLP as our new
principal accountant. This selection was presented to our shareholders and
ratified at our annual meeting of shareholders, which took place on May 19,
1999.

Compensation of Directors

         Directors who are regularly employed officers of the Company receive no
fees for serving as directors of the Company. Each non-officer director receives
$20,000 (the Chairman receives $30,000) per year plus $1,000 per day of meetings
of the Board or Committee of the Board attended, and each may elect to receive
such compensation in shares of common stock. Upon his election to the Board in
1999, Olivier Degos received options to purchase 10,000 shares of common stock
exercisable at $15.938 per share (the price per share on the date of the grant).
Upon his election to the Board in 1998, Patrick Buffet received options to
purchase 10,000 shares of common stock exercisable at $10.625 per share (the
price per share on the date of the grant).Upon his election to the Board in
1997, Philippe Brongniart received options to purchase 10,000 shares of common
stock exercisable at $25.00 per share (the price per share on the date of the
grant). Upon their election to the Board in 1995, Messrs. Bleitrach and Mangin
d'Ouince each received options to purchase 10,000 shares of common stock
exercisable at $22.13 per share (the price per share on the date of the grant).
During 1994, each individual who was then a Director received options to
purchase 10,000 shares of common stock (20,000 for the Chairman) exercisable at
$15.75 per share (the price per share on the date of the grant). In July 1996
the Chairman received additional options to purchase 10,000 shares of Common
Stock exercisable at $18.75 per share. Each Director is reimbursed for the
out-of-pocket costs of attending meetings. Ms. Christine Morin-Postel did not
receive options upon her election to the Board when elected Chairman in January,
2000.

EMPLOYMENT AGREEMENTS

         The Company has entered into employment agreements (the "Employment
Agreements") with Thomas R. Casten, Richard E. Kessel and Eugene E. Murphy,
("Named Executive Officers"). Each of the Employment Agreements was initially
for a period of three years commencing as of August 12, 1994 and is renewable
for additional annual extensions unless terminated by either party. The base
salaries under the Employment Agreements are subject to review by the
Compensation Committee. The Employment Agreements also provide for the payment
of incentive compensation. An Employment Agreement for a particular Executive
Officer contains other specified benefits only if those benefits have been
approved by a member of the Board of Directors who has been authorized to review
and approve such provisions. Mr. Casten's employment terminated on January 19,
2000.

         On January 19, 2000 Mr. Casten entered into an agreement with Elyo
pursuant to which Mr. Casten shall sell his shares of Stock in Trigen to Elyo,
and Elyo shall purchase such shares on the thirty-first (31st) calendar day
following the filing of Schedule TO by Elyo and certain of its affiliates in
connection with the offer by T Acquisition Corp., a Delaware corporation and an
indirect, wholly owned subsidiary of Elyo, to purchase any and all of the
outstanding shares of Trigen.

         Also on January 19, 2000, Mr. Casten entered into a Separation
Agreement and Release (the "Separation Agreement") with Trigen whereby Mr.
Casten resigned as a director and officer of Trigen effective January 19, 2000.
Pursuant to the Separation Agreement, Mr. Casten resigned from his positions as
President, Chief Executive Officer and a director of Trigen and is eligible for
salary and benefits continuation until the earlier of (a) January 19, 2002, or
(b) the date on which he breaches any of his obligations under the Separation
Agreement. Mr. Casten's obligations include non-disparagement, non-competition,
cooperation, non-solicitation and confidentiality covenants. If Mr. Casten
breaches any of these covenants, his right to payments under the terms of the
Separation Agreement will be extinguished. Restricted


                                       22
<PAGE>


stock and unvested options held by Mr. Casten will continue to vest in
accordance with their terms as if Mr. Casten remained employed by the Company
and to the extent not vested on January 19, 2002 will become fully vested on
that date to the extent not previously canceled by reason of a breach of the
Separation Agreement. Alternatively, immediately prior to the effective time of
the merger, if the merger occurs, (i) Mr. Casten's options will be canceled and
he will receive for each share subject thereto the excess of the merger
consideration over the exercise price, and (ii) Mr. Casten's shares of
restricted stock will be canceled and he will receive an amount per share equal
to the merger consideration in respect of one-fourth of such shares and will be
eligible to receive on January 19, 2002 an amount per share equal to the merger
consideration in respect of three-fourths of such shares. Mr. Casten is entitled
to remain a general partner of the Trenton District Energy Company ("TDEC"), but
may not interfere with or participate in the day-to-day operations of TDEC.
Trigen has agreed that if TDEC refinances, Trigen will, subject to certain
exceptions, use its good faith efforts so that Mr. Casten does not recognize
income as a result of such refinancing as long as such efforts do not adversely
impact TDEC, Trigen or its affiliates.

REPORT OF THE COMPENSATION COMMITTEE

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

         All decisions on compensation of the Company's executive officers,
including decisions about awards under certain of the Company's stock-based
compensation plans, are made by the members of the Compensation Committee, each
of whom is a non-employee director. This report addresses the Company's
compensation policies for 1999 as they affected Messrs. Casten, Kessel, Murphy,
Smith and Stone, the chief executive officer and the four highest paid executive
officers of the Company for 1999 (collectively, the "Named Executive Officers").

COMPENSATION POLICIES

         The Compensation Committee's executive compensation policies are
designed to (a) provide competitive compensation opportunities when financial
and operational performance attains pre-set ambitious levels, (b) reward
executives consistent with the Company's performance, (c) recognize individual
performance and responsibility, (d) underscore the importance of shareholder
value creation, and (e) assist the Company in attracting, retaining and
inspiring qualified executives. The overall focus of the compensation policy is
to balance the near-term goals and needs of management and other employees with
the long-term perspective to drive performance and results to provide a
consistent commitment to the growth of the Company and enhance the creation of
shareholder value.

         The principal elements of compensation employed by the Committee to
meet these objectives are base salaries, annual cash incentives, business
development incentives, and long term stock-based incentives. By design, the
variable or "at-risk" components of compensation are proportionately greater for
more senior executives, in recognition of their greater potential impact on the
Company's results.

         All compensation decisions are determined following a detailed review
of many factors that the Committee believes are relevant, including external
competitive data, the Company's achievements over the past year, the
individual's contributions to the Company's success, any significant changes in
role or responsibility, and the reasonableness of compensation in relation to
that of other employees.

         The competitiveness of the Company's total compensation program
(incorporating base salaries, annual cash bonuses, and long term stock-based
incentives) is assessed regularly with the assistance of an independent expert
compensation consultant. Comparisons are made with executives in similarly sized
firms with comparable responsibilities. Data for these comparisons is drawn from
two primary sources: (1) a national compensation survey of similar publicly
traded companies, and (2) the proxy statements of identified competitors,
including all companies within a selected group of peer industry organizations
(the "Compensation Peer Groups").

         One of the guiding principles is to pay at a level that allows the
Company to compensate key executives competitively compared with similarly
placed executives within the Compensation Peer Groups. This comparison is
performed while considering the Company's performance in relation to the
performance results of those companies. In general, the Committee intends to pay
base salary levels at the median or average levels of competitive compensation
for executives with comparable responsibilities in the Company's Compensation
Peer Groups. In addition to base salary, the Company's total compensation
program includes an annual cash incentive plan, a business development growth
incentive and a long-term stock-based incentive program. The targeted total
compensation levels for the Named Executive Officers


                                       23
<PAGE>


are intended to be consistent with competitive levels (as measured by the total
compensation levels of similar positions at the Compensation Peer Groups) when
the Company attains its targeted corporate performance objectives. Actual
payouts, if any, depend upon actual Company performance. Thus, the total
compensation levels and individual compensation components received in any
particular year could be demonstrably lesser or greater than the Compensation
Peer Groups' average.

         The Company compensation philosophy for senior management emphasizes
pay at risk, highlights a long-term performance results perspective, provides
executive commitment via stock ownership, and bolsters the creation of
shareholder value.

         BASE SALARY. Base salaries for all Named Executive Officers, including
the Chief Executive Officer, are reviewed by the Committee on an annual basis.
In determining appropriate base salaries, the Committee considers external
competitiveness, the roles and responsibilities of the individual, the
reasonableness of compensation in relation to that of other employees, and the
contributions of the individual.

         ANNUAL CASH INCENTIVES. The Company believes that its incentive
compensation plan should reward executives and other employees for their
contributions to the success and profitability of the business, as well as the
achievement of their personal goals and objectives which support the overall
growth of the Company. Incentives paid under the Incentive Compensation Plan
reflect the Committee's assessment of the degree to which the Company and
business units met predetermined earnings per share and profitability
objectives, and the executives and other participants achieved their individual
goals and objectives that were agreed to between the Company and the executive.
All Named Executive Officers, including the Chief Executive Officer, are
eligible to participate in this program.

         LONG TERM STOCK-BASED INCENTIVES. The Company also believes that it is
essential to link management and shareholder interests. To meet this objective,
the Company implemented the 1994 Stock Incentive Plan ("Stock Plan"), which
allows the Committee to grant stock options, restricted stock, performance
shares, and stock appreciation rights to help attract, retain, and inspire
executives and other employees by providing them with an opportunity to share in
the Company's success. In determining actual awards, the Committee considers the
externally competitive market, the contributions of the individual to the
success of the Company, and the need to retain the individual over time. All
Named Executive Officers, including the Chief Executive Officer, are eligible to
participate in this program. The Company implemented a long-term program in 1997
under the Stock Plan in which senior management, including all Named Executive
Officers, were granted a combination of incentive stock options and restricted
shares. A key component of this program is for management to meet share
ownership goals in order to participate fully in this program.

         By encouraging employees to obtain a stake in the Company's on-going
success, the Company believes this will focus employees' attention on managing
the Company as a shareholder with an equity position. The Company intends to
continue granting stock options on a periodic basis to its employees,
executives, and directors.

         The Committee has reviewed Internal Revenue Code Section 162(m) and has
determined that, at present, its limitations are not applicable to the Company.
Annually, the Committee will continue to consider the implications of this
statute.

         The Committee's policy regarding the compensation of other executive
officers of the firm is consistent with the approach outlined here.

1999 COMPENSATION

         As in prior years, the Company engaged the services of an outside,
independent compensation consulting firm to conduct and verify to the Committee
its findings concerning the compensation levels and practices of the
Compensation Peer Groups and its recommendations for compensation actions for
the Named Executive Officers. As outlined under "Compensation Policies", the
Committee is thoroughly committed to the Company's variable pay concept. Under
this philosophy, the Company is driven to leverage its compensation dollars and
reward high performance levels when the Company's shareholder value added levels
warrant.

         Base salaries paid in 1999 to the Named Executive Officers, including
the CEO, reflect the Committee's review of external competitiveness, the roles,
responsibilities and contributions of the individuals and the reasonableness of
compensation in relation to that of other employees.


                                       24
<PAGE>


         Incentive Compensation Plan incentives to be paid to all Named
Executive Officers for 1999 were determined in conjunction with the Committee's
assessment of the Company's performance with respect to predetermined earnings
per share and profitability objectives. Overall, the Company's performance as
measured by earnings per share was significantly above the target levels
established in 1999 for the Incentive Compensation Plan. Accordingly, the CEO
and the other Named Executive Officers received an incentive proportionately
greater than their individual target levels for 1999. In addition to the
Corporate earnings per share target, the business units in 1999 also were
measured by an operating income performance criteria. Most business units did
achieve their goals although two business units were below their threshold, and
the remaining business units were slightly below their assigned threshold
levels. Overall, the incentive levels are greater than the approved target
levels for those Named Executive Officers who did receive an incentive.

         The Company launched a long-term stock-based compensation program in
1997. The program's primary objective is to focus management on increasing
shareholder value. The program has three components: a) stock ownership goals,
b) a restricted share award, and c) an incentive stock option grant. The
restricted shares, which have a life cycle of eight years, will remain
restricted until the Company announces accumulated basic earnings per share over
four consecutive fiscal quarters of $2.08. This earnings target represents a
doubling of the Company's 1996 earnings per share figure. In addition to the
earnings target, the shares are also restricted from vesting unless the
participant achieves his/her prescribed stock ownership levels. Each
participant, including the Named Executive Officers, have been provided with a
stock ownership target. The stock ownership targets are stated as a percentage
of the participant's restricted share award and the percentages are progressive
based on the increase in role and responsibility.

TRENTON PARTNERSHIP

         Trigen-Trenton Company, L.P., a limited partnership ("Trigen-Trenton"),

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of
TRIGEN ENERGY CORPORATION:

We have audited the accompanying consolidated balance sheets of Trigen Energy
Corporation and subsidiaries as of December 31, 1999 and 1998 , and the related
consolidated statements of operations, cash flows and stockholders' equity for
the years then ended. These consolidated financial statements and financial
statement schedules 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 in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Trigen Energy
Corporation and subsidiaries as of December 31, 1999 and 1998, and the results
of its operations and its cash flows for the years then ended in conformity with
accounting principles generally accepted in the United States.

Our audit was made for the purpose of forming an opinion on the basic financial
statements taken as a whole. The schedules listed in the accompanying index are
presented for purposes of complying with the Securities and Exchange
Commission's rules and are not a required part of the basic financial
statements. These schedules, as of December 31, 1999 and 1998 and for the years
then ended, have been subjected to the auditing procedures applied in our audit
of the basic financial statements and, in our opinion, fairly state, in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION

         Trigen Energy Corporation (the "Parent Company", and together with its
subsidiaries, "We") develop, own and operate commercial and industrial energy
systems in the United States, Canada and Mexico. We use our expertise in thermal
engineering and proprietary cogeneration processes to convert fuel to various
forms of thermal energy and electricity. We combine heat and power generation,
producing electricity as a by-product, for use in our facilities and for sale to
customers.

         Suez Lyonnaise Des Eaux, a French corporation, through its energy
services affiliate Elyo, a French corporation, owns 52.8% of our common stock.
We have entered into a licensing agreement with Elyo to provide us with
technical assistance to construct, operate and maintain community energy systems
within North America, as well as the right to use patents and licenses of Elyo
in connection with the generation and distribution of electricity, chilled water
and waste incineration.

         Subsequent to year end, we have entered into an agreement with Elyo in
which Elyo will purchase all of the outstanding shares that it does not already
own (See Note 22 of Notes to Consolidated Financial Statements).

         We have established joint ventures with electric utilities to develop
and operate combined heat and power plants. Our equity share in the operating
results of these joint ventures is reported in equity in earnings/(losses) of
non-consolidated partnerships in the Consolidated Statements of Operations.

         A significant portion of our revenues and operating profit are subject
to seasonal fluctuation due to peak heating demand in the winter and peak
cooling demand in the summer.

2. SUMMARY OF ACCOUNTING POLICIES

RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS No. 133"). SFAS No. 133 establishes
accounting and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts, and for hedging activities.
In July 1999, SFAS No. 137 was issued, which deferred the effective date of SFAS
No. 133. We will adopt SFAS No. 133 effective January 1, 2001. Based on
preliminary analyses, we do not expect that the future adoption of SFAS No. 133
will have a material effect on results of operations and financial condition.

         In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities" ("SOP 98-5"). SOP 98-5 requires costs of start-up activities and
organizational costs to be expensed as incurred. SOP 98-5 is effective for
financial statements for fiscal years beginning after December 15, 1998. We
adopted SOP 98-5 effective January 1, 1999. The effect of the adoption was an
after-tax charge of $4.9 million net of a tax benefit of $3.5 million, to
expense deferred organizational and start-up costs as a cumulative effect of a
change in an accounting principle.

PRINCIPLES OF CONSOLIDATION

         The consolidated financial statements include the accounts of the
Parent Company and all wholly-and majority-owned subsidiaries. Intercompany
accounts and transactions are eliminated.

         Certain reclassifications have been made to the prior years' financial
statements to conform to the 1999 presentation.

                   TRIGEN ENERGY CORPORATION AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

USE OF ESTIMATES

         The preparation of financial statements in accordance with generally
accepted accounting principles 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 date of the financial
statements, and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.

REVENUE RECOGNITION

         Revenue for energy sold includes both fixed charges and amounts based
on energy delivered. Contract rates are either directly negotiated with the
customer or approved by the applicable regulatory authority. Sales not billed by
month-end are accrued based upon estimated usage. Fees earned are recognized as
services are performed.

         There is one customer whose revenues were more than 10% of total
revenues in 1999. Revenues for the one customer were 11%, 12% and 13% of total
revenues in 1999, 1998 and 1997, respectively. Another customer accounted for
11% and 13% of total revenues in 1998 and 1997, respectively. The one customer
accounted for 6.9% of the total trade receivable balance at December 31, 1999.

CASH AND CASH EQUIVALENTS

         Cash and cash equivalents include demand deposits and temporary
investments in high-grade instruments with original maturities at date of
purchase of three months or less.

FUEL EXPENSE AND DEFERRED FUEL

         Certain of our subsidiaries, either as a result of regulation or
contractual agreements with their customers, are allowed to recover all or
substantially all of their fuel costs, which is our largest expense. Certain of
these subsidiaries estimate the future cost of fuel in current contract rates.
Differences between the estimated fuel costs and actual fuel costs are deferred
and subsequently charged to or rebated to the customer through future rate
adjustments.

INVENTORIES

         Inventories are comprised principally of fuel, operating supplies and
spare parts. Fuel inventories are stated at cost determined on a first-in,
first-out basis and materials and supplies and spare parts are stated at average
cost. The portion of spare parts inventories not expected to be used within one
year is classified as non-current.

PROPERTY, PLANT AND EQUIPMENT

         Property, plant and equipment are recorded at cost. Depreciation is
computed by the straight-line method over the estimated useful lives commencing
when assets, or major components thereof, are placed in service. Renewals or
betterments are capitalized, while maintenance and repair costs are expensed.

DEFERRED COSTS AND OTHER ASSETS

         Included in deferred costs and other assets are capitalized costs
associated with debt financing, deferred contract costs, development projects
and other non-current assets. Financing costs are capitalized and amortized over
the debt term using methods that approximate the interest method. Deferred
contract costs are costs incurred to complete certain energy contracts. These
costs are deferred and amortized over the contract period. Costs incurred in
developing energy generation facilities after the execution of a letter of
intent are accumulated by project and included in the acquisition cost or as
construction in process for that project.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

INTANGIBLE ASSETS

         Included in intangible assets are costs in excess of the net assets of
acquired companies, non-compete agreements with former majority owners of
acquired companies, a fuel management contract and organization costs. The costs
in excess of the net assets of acquired companies is being amortized over
periods not exceeding 32 years. The non-compete and fuel management agreements
are being amortized over the terms of the agreements, 15 and 19 years,
respectively. We continuously assess the recoverability of these intangible
assets by evaluating whether the amortization of the intangible assets over the
remaining lives can be recovered through expected future results. Expected
future results are based on projected undiscounted operating results before the
effects of intangible amortization. The amount of impairment, if any, is
measured based on projected discounted future results, using a discount rate
reflecting our average cost of funds.

FOREIGN CURRENCY TRANSLATION

         Income and expenses of Canadian subsidiaries are translated to U. S.
dollars at rates in effect during the year, and assets and liabilities at
year-end rates. Translation adjustments are included in stockholders' equity in
the Consolidated Balance Sheet. Foreign currency transaction gains and losses
are included in net earnings.

FINANCIAL INSTRUMENTS

         We use financial instruments to limit the financial risk of increases
in interest rates on its floating rate debt. The differential to be paid or
received under financial instruments is accrued and recognized in interest
expense as interest rates change.

INCOME TAXES

         We use the asset and liability method of accounting for income taxes
following the provisions of Statement of Financial Accounting Standards No. 109
"Accounting for Income Taxes." Under this method, deferred tax assets and
liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities, and their respective tax bases. Deferred income tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled.

ENVIRONMENTAL EXPENDITURES

         Expenditures that relate to an existing condition, which do not
contribute to current or future revenue generation and expenditures incurred for
environmental compliance with respect to pollution prevention and ongoing
monitoring programs, are expensed as incurred. Expenditures that increase the
value of the property are capitalized.

EARNINGS PER COMMON SHARE

         Following is a reconciliation of basic earnings per common share to
diluted earnings per common share for the three years ended December 31, 1999
(in thousands, except per share data).

3.   SUPPLEMENTARY INCOME INFORMATION

         Included in other income, net for the year ended December 31, 1999, is
a pre-tax gain of $14.5 million related to the Grays Ferry Cogeneration
Partnership litigation settlement agreement. The gain represents the market
value of the share of the Partnership that we received as part of this
settlement. (See Note 23 of Notes to Consolidated Financial Statements, Legal
Proceedings). In addition, included in other income, net for the year ended
December 31, 1999, is a pre-tax gain of $1.8 million associated with the sale of
marketable securities. Included in other income, net for the year ended December
31, 1998, were pre-tax gains of $2.1 million from the sale of nitrogen oxide
emission allowances and $1.7 million from an insurance settlement.

4.   CUMULATIVE EFFECT OF A CHANGE IN AN ACCOUNTING PRINCIPLE

         Effective January 1, 1999, we adopted the American Institute of
Certified Public Accountants Statement of Position No. 98-5, "Reporting on the
Costs of Start-Up Activities" ("SOP 98-5"). SOP 98-5 requires that costs
associated with start-up activities and organizational costs be expensed as
incurred. The effect of the adoption was an after-tax charge of $4.9 million,
net of a tax benefit of $3.5 million, to expense deferred organizational and
start-up costs as a cumulative effect of a change in an accounting principle.

5.   EXTRAORDINARY ITEM

         We incurred extraordinary charges of $.3 million during 1998, net of a
tax benefit of $.2 million, in connection with the early retirement of debt.

6.   ACQUISITIONS

         On January 22, 1998, we acquired all of the capital stock of Power
Sources, Inc. (renamed Trigen-BioPower, Inc.), a biomass-to-energy power plant
developer and operator, for a total cash investment of $44.1 million, funded
from our existing credit facility. Results for Trigen-BioPower have been
consolidated with our results since the date of acquisition.

         The acquisition was accounted for under the purchase method of
accounting. The purchase price has been allocated to the assets acquired and
liabilities assumed based on fair market value at the date of acquisition. The
excess of the purchase price over the net assets was $10.4 million and is being
amortized over a period of 30 years. The fair value of the assets acquired and
liabilities assumed is as follows (in thousands):

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


         The pro forma results included certain adjustments for depreciation
expense as a result of a step up in the basis of property, plant and equipment
and an increase in the remaining useful lives, amortization expense as a result
of goodwill and other intangible assets and interest expense on borrowings to
finance the acquisition. The pro forma results do not purport to be indicative
of the results of operations which actually would have resulted had the
acquisition been made at the beginning of the year presented, or of results
which may occur in the future.

         On September 23, 1998, we purchased an additional 48% interest in the
Trigen-Nations Energy Company Limited Partnership from Nations Energy
Corporation for $21.3 million. This limited partnership owns the energy
production assets in service to Coors Brewing Company in Golden, Colorado. On
June 22, 1999, we purchased an additional 1% of the limited partnership for $.3
million. The combined excess of purchase price over the net assets purchased was
$9.6 million and is being amortized over a period not exceeding 32 years. These
purchases increased our investment in Trigen-Nations Energy Company from 51% to
100%.

7.   RESTRICTED FUNDS

         Under the terms of our debt agreements, a portion of the cash of the
operating subsidiaries is restricted in use, first to paying the operating costs
of the respective subsidiary, then its debt service obligations, in the priority
stipulated in the respective debt agreements. Restricted funds at December 31,
1999 and 1998 were (in thousands):

         At December 31, 1999, we had purchase commitments for fuel at prices
discounted from the spot market and at fixed prices. The aggregate commitment
under these contracts is estimated to be $14.2 million based on current spot
prices. These contracts expire at varying dates from March 2000 through December
2000. We have fuel cost pass-through clauses in our rates with customers for all
of these commitments.

         Substantially all of our assets are pledged as collateral under our
debt agreements (See Note 13 of Notes to Consolidated Financial Statements). In
1999, we recognized an asset impairment loss of $3.0 million ($1.8 million net
of tax) in accordance with SFAS 121 "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be Disposed Of". This loss is the difference
between the carrying value of the long-lived assets of a division of our
Canadian subsidiary and the fair value of those assets based on discounted
estimated future cash flows. The loss is included in depreciation expense.

and, upon approval of the lender, for additional one year periods thereafter.
The UTC Revolver is secured pro rata with the UTC Term Loan (See Note 13 of the
Notes to Consolidated Financial Statements). UTC is required to have 60
consecutive days each year with no outstanding borrowings under the UTC
Revolver. UTC has several interest rate options under the UTC Revolver including
LIBOR. The balance outstanding under this facility at December 31, 1999 and 1998
was $15 million, and the average rate on this borrowing was 6.4% in 1999 and
6.5% in 1998. The effective rate at December 31, 1999 was 7.3%.

</TABLE>


(a)  On April 4, 1997, we entered into a $160.0 million revolving credit
     agreement with several banks. This facility was used to repay indebtedness
     outstanding under a $62.5 million credit facility entered into in 1995. The
     $160.0 million facility is for an initial period of three years and may be
     extended by a total of two one-year periods. Borrowings under the facility
     bear interest, at our option, at an annual rate equal to the base rate or
     the LIBOR rate plus3/4%. The base rate is the higher of the prime lending
     rate or the Federal Reserve reported Federal funds rate plus1/2%. On June
     10, 1997, we amended the $160.0 million credit agreement by reducing the
     facility to $125.0 million and entered into a $35.0 million revolving
     credit facility with the same group of banks. The new facility is for an
     initial 364-day period and may be extended annually at the option of the
     banks. The terms and conditions of both facilities are the same. On
     September 23, 1998, the $125.0 million three year facility was increased by
     $35.75 million and the initial period was increased by one year. The base
     rate is the higher of the prime lending rate or the Federal Reserve
     reported Federal funds rate. The average effective rate on the facility was
     6.0% in 1999 and the rate at December 31, 1999 was 7.2%.

(b)  The UTC term loan and the UTC Revolver (Note 12) (together the "UTC Debt")
     are secured by all the assets and revenues of UTC. The Parent Company has
     guaranteed the UTC Debt in an amount which is limited, except for
     liabilities of UTC arising from environmental matters, to the lesser of
     $31.7 million and one-third of the UTC Debt commitments.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     Interest on the UTC term loan is at variable rates based on LIBOR. The
     average effective rate was 7.3% in 1999, 7.8% in 1998 and 7.3% in 1997. The
     rate at December 31, 1999 was 8.1%. UTC has purchased interest rate
     protection agreements (See Note 14 of Notes to Consolidated Financial
     Statements). Principal repayments commenced in June 1994, with final
     maturity in September 2004.

(c)  Interest on the Nassau term loan is at variable rates based on LIBOR. The
     average effective rate was 6.4% in 1999, 6.8% in 1998 and 6.7% in 1997. At
     December 31, 1999, the effective rate was 7.2%. Principal repayments
     commenced in June 1992, with final maturity in December 2003.

     The Nassau bonds were issued by the Town of Hempstead Industrial
     Development Authority. In February 1998, the Nassau bonds were refinanced
     as variable rate demand tax-exempt industrial development bonds. A bank has
     issued a letter of credit in favor of the bondholders in the event of
     default. Interest is variable, and the average effective rate was 3.2% in
     1999.

     The Nassau term loan and the Nassau bonds are without recourse to the
     Parent Company. All the assets and revenues of Trigen-Nassau Energy
     Corporation ("Trigen-Nassau"), a wholly owned subsidiary of the Parent
     Company are pledged to secure the term loan and bonds. Upon certain events,
     Trigen-Nassau will be required to enter into interest rate protection
     agreements the effect of which is to fix the rate on 50% of the aggregate
     outstanding principal amounts of the term loan and bonds for a minimum of
     five years.

(d)  The Trenton bonds were issued by the New Jersey Economic Development
     Authority, and are payable solely from revenues and other funds pledged by
     Trigen-Trenton Energy Company, L.P., a majority-owned subsidiary of the
     Parent Company. The bonds require annual sinking fund payments that began
     December 1993 with final maturity in December 2010. The interest rates were
     fixed to maturity at 6.1%-6.2% on $34.6 million of the bonds (the
     tax-exempt portion).

(e)  Interest on the Oklahoma term loan is at variable rates based on LIBOR. The
     average effective rate was 6.6% in 1999, 7.0% in 1998 and 7.1% in 1997. The
     rate at December 31, 1999, was 7.0%. Principal repayments commenced in
     December 1994, with final maturity in September 2007.

     The Oklahoma bonds were issued by the Oklahoma City Industrial and Cultural
     Facilities Trust. Interest is 6.75% per year. Principal payments are due
     from 2008 through 2017. A bank has issued a letter of credit in favor of
     the bondholders in the event of default.

     The Oklahoma term loan and the Oklahoma bonds are without recourse to the
     Parent Company. All the assets of Trigen-Oklahoma Energy Corporation
     ("Trigen-Oklahoma"), a wholly owned subsidiary of the Parent Company, are
     pledged to secure the term loan and bonds. Upon certain events,
     Trigen-Oklahoma will be required to enter into interest rate protection
     agreements the effect of which is to fix the rate on 75% of the aggregate
     outstanding principal amounts of the term loan and bonds for an average
     life of seven years.

(f)  Interest on the term loan for Trigen Energy Canada Inc., a wholly owned
     subsidiary of the Parent Company, ("Trigen-Canada") was at variable rates
     during 1999 based on Canadian bankers' acceptances. The average effective
     rate was 6.3% in 1999, 5.39% in 1998 and 4.6% in 1997. At December 31,
     1997, Trigen-Canada entered into an interest rate swap agreement fixing the
     rate on the outstanding principal amount (See Note 14 of Notes to

     The term loan is secured by the assets of Trigen-Canada, with limited

(h)  Trigen-BioPower bonds were issued by the Development Authority of St.
     Mary's (Georgia) as variable rate demand tax-exempt pollution control
     revenue bonds. A bank has issued a letter of credit in favor of the
     bondholders in the event of default. Interest is variable, and the average
     effective rate was 3.68%. The Parent Company has guaranteed this debt.

(i)  On December 30, 1998, we borrowed from an affiliate, Cofreth American
     Corporation, $50.0 million for acquisitions and project development. The
     $50.0 million was initially used to partially pay down the Corporate
     facility. The $50.0 million is subordinate and junior in right of payment
     to all other debt. The subordinated debt may be redeemed in whole or in
     part at the option of Cofreth American Corporation with the net proceeds of
     an equity sale by the Company. The debt matures on December 31, 2010 and
     the interest rate is 7.38%.

         Our debt agreements limit or restrict cash payments, the payment of
dividends, capital expenditures, incurrence of new debt and transactions with
affiliates. At December 31, 1999, we were in compliance with all covenants
contained in our debt agreements (See Note 23 of Notes to Consolidated Financial
Statements for default information related to Grays Ferry Cogeneration
Partnership).

       Maturities of long-term debt for the next five years are as follows (in
thousands):

         Based upon the debt balances at December 31, 1999, a change in the
LIBOR rate of .25% would have a corresponding change in interest expense of
approximately $.8 million per year when three-month LIBOR is under 6.0% ranging
to approximately $.7 million per year when three-month LIBOR is over 7.5%.

Three-month LIBOR at December 31, 1999 was 6.00125%.

         Cash paid for interest was $23.8 million, $21.0 million and $17.3
million in 1999, 1998 and 1997, respectively.

14.  FINANCIAL INSTRUMENTS

         The estimated fair value of long term debt approximates carrying value
at December 31, 1999. The fair value of receivables, payables and short-term
debt approximates carrying value at December 31, 1999 due to the short-term
maturity of these instruments.

         As of December 31, 1999, we had outstanding interest rate swap, cap and
collar agreements related to $39.4 million of debt outstanding, with an average
fixed interest rate of 6.2% and an average remaining life of 5 years. The fair
value of the swap, cap and collar agreements was a receivable of $1.5 million.

         In addition to the letters of credit issued with respect to the Nassau,
BioPower and Oklahoma bonds (See Note 13 of Notes to Consolidated Financial
Statements), we had outstanding a contingent liability for letters of credit of
$7.9 million at December 31, 1999.

15.  LEASES

         We have entered into various leasing arrangements for office space,
land and equipment. These arrangements are accounted for as operating leases.

</TABLE>


         Excluded from the above future minimum rental payments are two
operating leases, one for a term of 25 years and the other for 99 years. The
25-year lease is for land, facilities and equipment and the 99-year lease is for
land. The current annual rental payments for these leases are $1.0 million and
the total remaining commitments at December 31, 1999 are estimated to be $27.5
million.

         Rental expense was $4.4 million in 1999, $4.2 million in 1998 and $3.7
million in 1997.

16.  STOCK OPTIONS

         Our stock incentive plan provides for the granting of stock options,
stock appreciation rights, performance shares, restricted stock and other stock
awards to officers and key employees and stock options to non-employee
directors. In 1997, shareholders approved an increase in the number of shares of
common stock that may be issued under the stock incentive plan to 2,000,000
shares.

         Stock options outstanding under the stock incentive plan were granted
at a price equal to 100% of the market price on the date of grant. Stock options
granted to non-employee directors are exercisable six months from the date of
grant, and are exercisable until the earlier of the tenth anniversary of the
date of grant, or the first anniversary of leaving the Board of Directors. Stock
options granted to employees vest at the rate of 20% per year, starting on the
first anniversary of the grant date and are exercisable over a period of ten
years from the date of grant, with the exception of grants of stock options in
1995 for 18,800 shares, which vested immediately.

         During 1998, we reviewed the stock option program and approved an
option exchange program covering 291,100 outstanding stock options which were
granted under the 1997 stock-based compensation program with stock exercise
prices greater than $14.00 per share. This exchange program provided that all
eligible management had the right to exchange existing options with strike
prices greater than $14.00 for new options with a strike price of $14.00.

Information relating to stock options granted during 1999, 1998 and 1997 is
summarized as follows:

---------
(a)  Average contractual life remaining in years.

         We apply APB 25 in accounting for our stock option plan. Accordingly,
compensation expense would be recorded on the date of grant only if the current
market price of our common stock exceeded the exercise price. Had compensation
expense for the stock option plan been determined based on the fair value at the
grant dates for awards under the plan consistent with SFAS No. 123, net earnings
would have decreased by $.6 million ($.05 per common share) and $.6 million
($.05 per common share) in 1999 and 1998, respectively.

         The fair value of each option was estimated on the date of grant using
the Black Scholes option-pricing model with the following assumptions: risk free
interest rates of 5.7 % and 5.3% for 1999 and 1998, respectively; annual
dividend yields of 1.22% for 1999 and 1998; expected option life of 8.1 years
for 1999 and 8 years for 1998; and volatility of 41% and 37% for 1999 and 1998,
respectively. The weighted average fair value of an option granted during 1999
and 1998 was $8.15 and $6.33 per share, respectively.

         Pursuant to the terms of the Merger Agreement (See Note 22 of Notes to
Consolidated Financial Statements) all options to acquire Trigen's stock will be
cancelled. Each holder of an option will receive an amount in cash equal to the
excess, if any, of the merger consideration over the per share exercise price of
such option without interest.

         In connection with the employee stock purchase plan, we allocated
200,000 shares of common stock for purchases pursuant to such plan. On September
9, 1999, we amended the 1994 Stock Purchase Plan to increase the number of
shares of stock available thereunder from 200,000 to 400,000. The amendment is
subject to approval by our stockholders. Stock purchased in 1999, 1998 and 1997
pursuant to the employee stock purchase plan was 63,367, 46,050 and 32,028
shares, respectively. The acquisition price of the stock is 85% of the lower of
the closing market price on the first and last day of the six-month purchase
period.

RESTRICTED STOCK

         We launched a long-term restricted stock-based compensation program in
1997. The program's primary objective is to focus management on increasing
shareholder value. The program has two components: (a) stock ownership goals;
and (b) a restricted share award. The restricted shares, which have a life cycle
of eight years, will remain restricted until we announce accumulated basic
Earnings per Share over four consecutive fiscal quarters of $2.08. This earnings
target represents a doubling of our 1996 Earnings per Share figure. In addition
to the earnings target, the shares are also restricted from vesting unless the
participant achieves his/her prescribed stock ownership levels. Each participant
has been provided with a stock ownership target. The stock ownership targets are
stated as a percentage of the participant's restricted share award and the
percentages are progressive based on the increase in role and responsibility.

         During 1999, we granted 32,400 restricted shares to certain employees.
Deferred compensation based on the market price of the stock on the date of the
grants totaling $.7 million was recorded in 1999. 5,525 restricted shares were
canceled in 1999 due to employees leaving the Company, resulting in a reduction
in unearned compensation of $.1 million. We are amortizing unearned compensation
into earnings over the vesting period of eight years.

         Pursuant to the terms of the Merger Agreement (See Note 22 of Notes to
Consolidated Financial Statements), these shares of restricted stock will be
cancelled and each holder will, promptly after the effective time of the merger,
receive, for each share of restricted stock, an amount of cash equal to
one-fourth of the merger consideration.

17.  RETIREMENT PLANS

         We sponsor a 401(k) Plan which allows participants to make
contributions pursuant to Section 401(k) of the Internal Revenue Code. We match
employee contributions in varying percentages according to a schedule up to an
annual maximum employer contribution of approximately $1,290 per employee.
Employees vest immediately in both employee and employer contributions. Employer
contributions to the 401(k) Plan were $1.1 million (including the cost of 47,646
shares of our common stock), $1.0 million (including the cost of 21,576 shares
of our common stock), and $1.1 million (including the cost of 23,902 shares of
our common stock) in 1999, 1998 and 1997, respectively. Effective January 1,
1995, the 401(k) Plan was open to all of our employees excluding certain
employees covered by other retirement plans.

         Benefits payable under a defined benefit plan were frozen as of
December 31, 1994 pending vesting and distribution to participants. Benefits
under the plan are based primarily on salary during the term of employment and
length of service. Pension expense was $42,000, $39,000 and $316,000 in 1999,
1998 and 1997, respectively. Our net obligation under the plan at December 31,
1998 was not significant.

         Net current deferred income tax assets of $5.5 million and $3.4 million
at December 31, 1999 and 1998, respectively, are included in prepaid expenses
and other current assets, net in the Consolidated Balance Sheet.

         At December 31, 1999, a loss carryforward of $2.9 million was available
to offset Canadian taxable income expiring $.7 million in 2003, $.9 million in
2004, $.8 million in 2005 and $.6 million in 2006. At December 31, 1999, an
alternative minimum tax credit carryforward of $5.8 million was available to
offset future U.S. regular income taxes, if any, over an indefinite period.
Valuation allowances were primarily for tax loss carryforwards in state and
local jurisdictions that may expire before being used. We believe that it is
more likely than not that we will generate taxable income sufficient to realize
the loss carryforwards prior to their expiration. This belief is based upon
projected taxable income and available tax planning strategies.

19.  EQUITY INVESTMENT IN GRAYS FERRY COGENERATION PARTNERSHIP

         As of December 31, 1999, we had an investment of $39.3 million in the
Grays Ferry Cogeneration Partnership (the "Partnership"), representing a
one-half interest in the Partnership through our wholly owned subsidiary
Trigen-Schuylkill Cogeneration, which is accounted for under the equity method.
Cogen America Schuylkill Inc. owns the other one-half interest in the
Partnership. We derive a significant portion of our income from the Partnership.
Included in our revenues for the year ended December 31, 1999 was our pre-tax
share of the Partnership earnings of $8.1 million and fees earned from the
Partnership of $3.1 million. The summarized financial information presented
below as of December 31, 1999 represents an aggregation of 100% of the
Partnership (in thousands).

----------

(a)   As of January 1, 1998, we changed our accounting policy for interim
      reporting for certain operating costs from an average costing method to an
      actual costing method. We believe that use of an actual costing
      methodology better reflects the results of our operations and conforms
      internal and external reporting of such results. This change effects
      interim quarterly reporting only and has no effect on an annual basis for
      the years ended December 31, 1999, 1998 and 1997 or on any prior years.
      The amounts presented above for 1998 and 1997 have been restated to
      reflect this change in accounting policy.

(b)   Reflects an after-tax charge of $4.9 million related to the adoption of
      SOP 98-5 "Reporting on the costs of Start-Up Activities" which was
      recorded as a cumulative effect of a change in accounting principle. See
      Note 4 of Notes to Consolidated Financial Statements.

(c)   Represents extraordinary losses of $.3 million, net of a $.2 million tax
      benefit, incurred in 1998, in connection with the early retirement of
      debt.

21.  CONTINGENCIES

         We are subject from time to time to legal proceedings and other claims
that arise in the normal course of business, and we believe, except as set forth
in Note 23 of Notes to Consolidated Financial Statements, that the outcome of
these matters will not have a material adverse effect on our results of
operations or financial condition.

22.  SUBSEQUENT EVENT

         On January 19, 2000, Trigen and Elyo, an energy subsidiary of the Suez
Lyonnaise des Eaux Group, jointly announced that they have entered into a
definitive merger agreement for Elyo to purchase all of the outstanding shares
of Trigen it does not already own for $23.50 a share in cash. Elyo's
subsidiaries currently own approximately 53% of Trigen common stock. On March
27, 2000, Elyo announced the completion of the tender offer. As of that date,
Elyo had beneficial ownership of aproximately 96% of Trigen's common stock.

23.  LEGAL PROCEEDINGS

OKLAHOMA LITIGATION

         In September 1996, our subsidiary, Trigen-Oklahoma City Energy
Corporation ("Trigen-Oklahoma City"), commenced an antitrust action in Federal
District Court in Oklahoma City seeking injunctions and actual, treble and
punitive damages from a local utility, Oklahoma Gas and Electric Company
("OG&E"), based on alleged anti-competitive actions against Trigen-Oklahoma City
Energy Corporation by OG&E. Trigen-Oklahoma City's antitrust action went to
trial in 1998 and on December 21, 1998, the jury returned a verdict in favor of
Trigen. On January 19, 1999, the Court entered a judgment in favor of Trigen in
the amount of $27.8 million. On January 25, 2000 the court decided post-trial
motions to vacate or modify the judgment reducing the judgment to $20.6 million.
OG&E has filed an appeal to the Tenth Circuit Court of Appeals and has posted a
bond in order to stay enforcement of the judgment pending appeal. Trigen has
filed a cross-appeal. Trigen's separate motion for attorney's fees (seeking
approximately $3 million) is pending but OG&E has requested that the court
postpone a hearing on that motion until the appeals are decided by the Circuit
Court. We have not recognized any gain with respect to this matter because we
cannot predict the final outcome.

KINETIC ENERGY LITIGATION

         On May 2, 1997, a judgment was entered against us in the amount of $4.3
million following a jury trial in a law suit by Kinetic Energy Development
Corporation against Trigen in the Circuit Court of Jackson County, Missouri, in
connection with our acquisition of the Kansas City steam system. Kinetic claimed
for compensation alleged to be owed to it by Trigen in connection with that
acquisition. On August 6, 1997, the Court set aside the jury verdict and granted
judgment for Trigen. Kinetic Energy Development Corporation appealed that order
and on December 8, 1998, the Missouri Court of Appeals set aside the lower court
decision and ordered a new trial. On December 22, 1998, we filed a motion for
rehearing with the Missouri Court of Appeals and/or a review by the Missouri
Supreme Court. The Court of Appeals granted our motion for rehearing. On
September 7, 1999, the Court of Appeals held that Kinetic had proven only
nominal damages at trial and returned the case to Circuit Court for retrial. The
retrial will allow Kinetic to attempt to establish that it is entitled to some
award for the reasonable value of its services, if any, in connection with the
Trigen acquisition of the Kansas City steam system. The case presently awaits
rescheduling for trial. We believe we have good defenses to these claims.
Accordingly, we have not recognized any loss or expense (other than defense
costs) with respect to this matter, although we cannot predict the final
outcome.

GRAYS FERRY LITIGATION

         On April 23, 1999, the Pennsylvania Court of Common Pleas of
Philadelphia County approved a settlement agreement which ended the lawsuit
brought by Grays Ferry Cogeneration Partnership (the "Partnership"),
Trigen-Schuylkill Cogeneration, Inc. and CogenAmerica Schuylkill Inc. against
PECO Energy Company and Adwin (Schuylkill) Cogeneration, Inc. The Partnership is
the owner of the Grays Ferry Cogeneration Facility located in Philadelphia,
Pennsylvania. The Partnership, Trigen-Schuylkill and CogenAmerica commenced this
lawsuit in reaction to the alleged termination by PECO on March 3, 1998, of the
electric power purchase agreements between the Partnership and PECO (the "Power
Purchase Agreements").

         Prior to the settlement, we owned a one-third interest in the
Partnership through our wholly owned subsidiary, Trigen-Schuylkill. CogenAmerica
and Adwin owned the other two-thirds interests in the Partnership. Adwin is an
indirect wholly owned subsidiary of PECO. Under the settlement agreement PECO's
subsidiary, Adwin, surrendered its rights to its one-third partnership interest
in the Partnership to the two remaining partners, Trigen-Schuylkill and
CogenAmerica. As a result, we own one half of the Partnership and CogenAmerica
owns the other half. During 1999, we recognized an after tax gain of $8.5
million ($.70 per diluted share) which represents the market value of our share
of Adwin's interest.

         In the year 2001, the energy price under the Power Purchase Agreements
will be based upon a percentage of a market based index, which we expect to
produce substantially lower revenues from sales to PECO than the more favorable
rates of the early contract years. Under the Settlement the Partnership gained
the right to sell to third parties electric energy and capacity from the
facility in excess of the 150 megawatts which PECO is required to purchase under
the Power Purchase Agreements, subject to a right of first refusal for PECO. We
expect that the ability to sell to third parties electric energy and capacity
above the 150 megawatts under contract to PECO, will result in an opportunity to
improve the financial performance of the Partnership. The Partnership will now
have the ability to institute capital modifications to the combustion turbine to
increase electric capacity during the summer months when the price of electric
capacity and energy are historically the highest.

         Separately, The Chase Manhattan Bank, as agent for several commercial
banks (collectively "Chase"), and Westinghouse Power Generation, which
collectively financed the construction of the Gray's Ferry Cogeneration
Facility, agreed to dismiss their lawsuits against PECO. Chase and Westinghouse
also agreed that they will not charge the Partnership for any default interest
up to April 16, 1999, although they have reserved the right to do so with
respect to the period after April 16, 1999.

         The Partnership is in default under its separate credit agreements with
Westinghouse and Chase for the following reasons. The Partnership did not
convert on time its short-term construction loan from Chase to a longer term
loan. The Partnership could not complete that conversion because of a dispute
with the construction contractor, which has now been resolved. The Partnership
also did not make principal payments to Westinghouse because the Chase loan
agreement prohibits such payments to subordinate parties while the Partnership
is in default. Westinghouse is a subordinate party.

         The Partnership owes a total principal amount of approximately $79.4
million to Chase. Chase has not accelerated the debt owing under the Credit
Agreement. Chase has required to date, and may require in the future, the
Partnership to apply available cash held by Partnership (net of operating
expenses) toward repayment of the principal amount of the loans outstanding to
Chase. The Partnership owes a total principal amount of approximately $15
million to Westinghouse. On March 1, 2000, Westinghouse demanded full payment of
the amount owing to Westinghouse under its credit agreement. Only the
Partnership assets and the Partners' ownership interests in the Partnership
secure the Partnership's debt under the Chase and Westinghouse loans.

         To resolve these matters we have negotiated an amendment to the credit
agreement with Chase and we are negotiating with Westinghouse and other
subordinate parties. The Partnership has accrued $3.0 million in default
interest since April 16, 1999.

NASSAU LITIGATION

         On May 29, 1998, the County of Nassau, New York commenced an action
against Trigen Energy Corporation and Trigen-Nassau Energy Corporation in New
York State Supreme Court. Trigen-Nassau provides energy services to Nassau
County under various agreements. Nassau County alleges that Trigen-Nassau
breached those agreements by, among other means, charging the County for certain
real estate taxes that the County contends are Trigen-Nassau's responsibility.
On October 8, 1998, the Court dismissed the claims against Trigen Energy
Corporation. On November 9, 1998, Trigen-Nassau filed counterclaims against
Nassau County, seeking $1.6 million in damages. Trigen-Nassau alleges that
Nassau County breached the parties' agreements by, among other things, failing
to operate and maintain certain facilities and equipment. On January 21, 1999,
the County requested that the Court dismiss Trigen-Nassau's counterclaims. On
April 5, 1999, the Court dismissed some but not all of Trigen-Nassau's
counterclaims. The Court declined to dismiss Trigen-Nassau's counterclaims that
seek approximately $1.5 million in damages. The County is seeking approximately
$10 million in damages. We believe we have good defenses to the County's claims.
Accordingly, we have not recognized any loss or expense (other than defense
costs) with respect to this matter, although we cannot predict the final
outcome.

ESI LITIGATION

         In 1996 ESI, Inc. commenced an action against, among others, Coastal
Power Company, Latin American Energy Development, Inc. and La Casa Castro S.A.
de N.V. in the United States District Court for the Southern District of New
York. On September 17, 1998, ESI, Inc. amended its complaint naming Trigen as an
additional defendant. This action arises out of the development by Trigen, Latin
American Energy, La Casa Castro and others, of an independent power project in
El Salvador between 1993 and 1994. Trigen transferred its interest in the
project to Tenneco Gas International in May 1994. In July 1994, Tenneco
transferred its interest in the project to Coastal Power Company, which
currently owns and operates the project. ESI claimed that ESI was entitled to a
2.5% interest in the project and that Coastal had wrongfully withheld or denied
ESI's interest. ESI further claimed that Trigen had failed to disclose ESI's
interest to Tenneco and so was responsible, in whole or in part, for ESI's
failure to receive a 2.5% interest in the project from Coastal.

         On October 8, 1998, Latin American Energy asserted cross-claims against
Trigen, Coastal and Tenneco claiming that it too had been denied its carried
interest in the Project. On October 28, 1998, La Casa Castro asserted
cross-claims against Trigen and on November 6, 1998, Coastal asserted
cross-claims against Trigen for indemnification, each alleged that Trigen failed
to disclose ESI's claimed interest to Tenneco and that Trigen was responsible
for any damages that each may be required to pay to ESI and Latin American.

         On December 15, 1998, Trigen filed an amended answer denying liability
for these claims and cross-claimed against Latin American Energy, Tenneco,
Coastal and La Casa Castro, asserting that these parties were responsible for
any damages owed to ESI and Latin American. On December 23, 1998, ESI and Latin
American dismissed without prejudice their claims against Trigen.

         Coastal and La Casa Castro are continuing to assert their claims
against Trigen for any damages they may be required to pay to ESI or Latin
American. At this time, the case is in the early stages of discovery and as such
we are not able to estimate the amount of damages that ESI and Latin American
are seeking. We believe we have good defenses to Coastal's claims and La Casa
Castro's claims. Accordingly, we have not recognized any loss or expense (other
than defense costs) with respect to this matter, although we cannot predict the
final outcome.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

SHAREHOLDER CLASS ACTIONS AGAINST TRIGEN

COMPLAINTS OF FOTHERGILL, CORTEZ, AND BERKOWITZ.

         On September 23, 1999, three complaints were filed in the Court of
Chancery of the State of Delaware against: Trigen Energy Corporation, Suez
Lyonnaise Des Eaux SA, Patrick Buffet, George F. Keane, Thomas R. Casten,
Philippe Brongniart, Olivier Degos, Patrick Desnos, Richard E. Kessel, Charles
E. Bayless, Michel Bleitrach, Dominique Mangin D'Ouince and Michel Cassou. The
individual defendants were sued in their capacity as Trigen directors and/or
former Trigen directors. The complaints were filed, respectively, by Michael
Fothergill, Rosa Cortez and Sarah Berkowitz. Each complaint was filed
purportedly as a class action on behalf of the Company's shareholders. The
complaints raised substantially identical allegations: that Trigen received a
proposal from Suez to take Trigen private for $22.00 per share in cash. The
plaintiffs alleged that this price does not represent the true value of Trigen
and is unfair to the minority shareholders. Plaintiffs further alleged that
because Suez owns approximately 52% of Trigen's outstanding shares, Suez has the
power to effectuate the transaction without regard to the minority shareholders.
Plaintiffs sought class certification, declaratory and injunctive relief (or
money damages if the transaction is consummated), and an accounting. By
agreement of the parties, an order has been entered consolidating all three
actions under the Fothergill caption.

         On February 22, 2000, counsel for ELYO and the plaintiffs reached an
agreement to settle this lawsuit, subject to court approval. The settlement does
not require any payment to the plaintiffs from the Company or its directors.
Accordingly, we have not recognized any loss or expense (other than defense
costs and certain costs of providing Notice of settlement to the Class members)
with respect to this matter, although we cannot predict the final outcome. The
parties are in the process of submitting this settlement to the Court of
Chancery of the State of Delaware for approval.

COMPLAINT OF RICE.

         On March 16, 2000, Adam Rice filed a complaint in the Supreme Court of
the State of New York, County of Westchester against Trigen Energy Corporation,
Suez Lyonnaise Des Eaux S.A., Elyo, S.A., T Acquisition Corporation, Christine
Morin-Postel, Richard E. Kessel, George Keane, Patrick Buffet, Olivier Degos,
Philippe Brongniart, Michel Bleitrach, Dominique Mangin D'Ouince and Charles
Bayless. The complaint was filed purportedly as a class action on behalf of the
Company's shareholders. The individual defendants were sued in their capacity as
Trigen directors. The plaintiff alleged that the defendants have breached their
fiduciary duties to plaintiff and our public shareholders by not renegotiating
and/or reformulating the terms of the tender offer by which T Acquisition
Corporation has offered to purchase all of our outstanding shares at a price of
$23.50 per share. Plaintiff seeks class certification and money damages as well
as other unspecified relief. We believe we have good defenses to these claims.
Accordingly, we have not recognized any loss or expense (other than defense
costs) with respect to this matter, although we cannot predict the final
outcome.

OTHER LITIGATION

         We are subject from time to time to various other claims that arise in
the normal course of business, and we believe that the outcome of these matters
(either individually or in the aggregate) will not have a material adverse
effect on our business results of operation or financial condition.

                                                         SCHEDULE I--(CONTINUED)

                   TRIGEN ENERGY CORPORATION (PARENT COMPANY)

             NOTES TO CONDENSED FINANCIAL INFORMATION OF REGISTRANT

(1)  TRIGEN ENERGY CORPORATION (PARENT COMPANY) FINANCIAL STATEMENTS

         The accompanying condensed financial information has been prepared in
accordance with Regulation S-X of the Securities Act of 1933 and does not
include all information and notes necessary for a fair presentation of financial
position, results of operations and cash flows in conformity with generally
accepted accounting principles since the user of these statements is assumed to
read them in conjunction with Trigen Energy Corporation's consolidated financial
statements and the notes thereto for the year ended December 31, 1999 included
elsewhere in this document.

(2)  TRANSACTIONS WITH SUBSIDIARIES

         The Parent Company derives cash from management fees and costs
recovered from its subsidiaries, distributions by its subsidiaries and, at
times, repayment to the Parent Company from proceeds of long-term financing
obtained by the subsidiaries for funds previously advanced to subsidiaries for
construction in advance of obtaining permanent financing. Certain subsidiaries
have restrictive debt agreements which generally permit distributions to the
Parent Company only when certain ratios and other financial covenants are
satisfied. Cash available to the Parent Company without restrictions as to use,
including amounts distributable by subsidiaries was $6.5 million at December 31,
1999, and $1.4 million at December 31, 1998.

(3)  DEBT

         On April 4, 1997, the Parent Company entered into a $160.0 million
revolving credit agreement with several banks. This facility was used to repay
indebtedness outstanding under a $62.5 million credit facility entered into in
1995. The $160.0 million facility is for an initial period of three years and
may be extended by a total of two one-year periods. Borrowings under the
facility bear interest, at the Parent Company's option, at an annual rate equal
to the base rate or the LIBOR rate plus 3/4%. The base rate is the higher of the
prime lending rate or the Federal Reserve reported Federal funds rate plus 1/2%.
On June 10, 1997, the Parent Company amended the $160.0 million credit agreement
by reducing the facility to $125.0 million and entered into a new $35.0 million
revolving credit facility with the same group of banks. The new facility is for
an initial 364-day period and may be extended annually at the option of the
banks. The terms and conditions of both facilities are the same. On September
23, 1998, the $125.0 million three year facility was increased by $35.75 million
and the initial period was increased by one year. The base rate is the higher of
the prime lending rate or the Federal Reserve reported Federal funds rate. The
average effective rate on the facility was 6.0% in 1999 and the rate at December
31, 1999 was 7.2%.

         The Parent Company has issued certain guarantees relating to the debt
of UTC. The Parent Company has guaranteed the UTC debt in an amount which is
limited, except for liabilities of UTC arising from environmental matters, to
the lesser of $31.7 million and one-third of the UTC debt commitments.

         On December 30, 1998, the Company borrowed from an affiliate, Cofreth
American Corporation, $50.0 million for acquisitions and project development.
The $50.0 million was initially used to partially pay down the Corporate
facility. The $50.0 million is subordinate and junior in right of payment to all
other debt. The subordinated debt may be redeemed in whole or in part at the
option of Cofreth American Corporation with the net proceeds of an equity sale
by the Company. The debt matures on December 31, 2010 and the interest rate is
7.38%.

(4)  INCOME TAXES

         The Parent Company and its domestic subsidiaries file a consolidated
U.S. Federal income tax return. The Parent Company's state income taxes are
filed on a separate return basis. A valuation allowance for state tax loss
carryforwards has been provided because there are carryforwards which may expire
before being used.
